Risk of expulsion low after early postpartum IUD placement
Intrauterine device (IUD) placement at 2-4 weeks postpartum was noninferior to placement at 6-8 weeks postpartum for complete expulsion, and carried only a slightly higher risk of partial expulsion. A randomized study of expulsion rates reports the risk of expulsion at these points may help patients and clinicians make informed choices about the timing of IUD insertion, wrote the study authors, led by Sarah H. Averbach, MD, MAS, an obstetrician-gynecologist at the University of California, San Diego. “We found that the risk of complete IUD expulsion was low at 2% after early IUD placement 2-4 weeks after delivery, and was noninferior to interval placement 6-8 weeks after delivery at 0%,” Dr. Averbach said in an interview.
Although the risks of partial expulsion and malposition were modestly greater after early placement, “the possibility of a small increase in the risk of IUD expulsion or malposition with early IUD placement should be weighed against the risk of undesired pregnancy and short-interval pregnancy by delaying placement.”
The timing of IUD placement in the postpartum period should be guided by patients’ goals and preferences, she added. The early postpartum period 2-4 weeks after birth has the advantage of convenience since it coincides with early-postpartum or well-baby visits. The absolute risk differences observed between early and interval placement were small for both complete or partial expulsion at 3.8%, and the rate for complete expulsion after early placement was much lower than historical expulsion rates for immediate postpartum placement within in few days of delivery.
Last year, a large study showed an increase in expulsion risk with IUD insertion within 3 days of delivery. Current guidelines, however, support immediate insertion as a safe practice.
The study
Enrolling 404 participants from diverse settings during the period of 2018 to July 2021, researchers for the noninferiority trial randomly assigned 203 to early IUD placement 14-28 days postpartum and 201 to standard-interval placement at 42-56 days. Patients had a mean age of 29.9 years, 11.4% were Black, 56.4% were White, and 43.3% were Hispanic (some Hispanic participants self-identified as White and some as Black). By 6 months postpartum, 73% of the cohort had received an IUD and completed 6-months of follow-up, while 13% had never received an IUD and 14% were lost to follow-up. Complete expulsion rates were 3 of 149, or 2.0% (95% confidence interval [CI], 0.4-5.8) in the early group and 0 of 145, or 0% (95% CI, 0.0-2.5) in the standard group, for a between-group difference of 2.0 percentage points (95% CI, −0.5 to 5.7, P = .04). Two women chose to replace their IUDs.
Partial expulsion occurred in 14, or 9.4% (95% CI, 5.2-15.3) of patients in the early group and 11, or 7.6% (95% CI, 3.9-13.2) in the standard-interval group, for a between-group difference of 1.8 (95% CI, −4.8 to 8.6) percentage points (P = .22).
The small absolute increase in risk of partial expulsion in the early arm did not meet the prespecified criterion for noninferiority of 6%. Three pelvic infections occurred in the early placement arm.
There were 42 IUD removals: 25 in the early placement group and 17 in the standard interval group. Thirteen participants had their IUDs removed for symptoms such as cramping and bothersome vaginal bleeding.
No perforations were identified in either group at 6 months, suggesting that the rate of uterine perforations is low when IUDs are placed in the early and standard-interval postpartum periods. IUD use at 6 months remained comparable between arms: 69.5% in the early group vs. 67.2% in the standard-interval group.
Commenting on the trial but not involved in it, Maureen K. Baldwin, MD, MPH, associate professor of obstetrics and gynecology at Oregon Health & Science University in Portland, said it provides further data on the prevalence of expulsion and malposition after placements using ultrasonography as needed. While two failures occurred with asymptomatic malposition, she added, “It should be noted that IUD position can change as a result of pregnancy, so it was not determined that malposition occurred prior to contraceptive failure.”
According to Dr. Baldwin, one strategy to reduce concerns is to use transvaginal ultrasonography at a later time or in the presence of unusual symptoms.
Overall, the study establishes that postpartum placement is an option equivalent to standard timing and it should be incorporated into patient preferences, she said. “Pain may be lowest at early placement compared to other timings, particularly for those who had vaginal birth.”
The study was supported by the Society of Family Planning research fund and the National Institutes of Health - National Institute of Child Health and Human Development. Dr. Averbach reported personal fees from Bayer Pharmaceuticals for advice on postpartum IUD placement as well as grants from the NIH outside of the submitted work. Dr. Baldwin disclosed no potential conflicts of interest with regard to her comments.

Ectopic pregnancy risk and levonorgestrel-releasing IUDs
Researchers report that use of any levonorgestrel-releasing intrauterine system was associated with a significantly increased risk of ectopic pregnancy, compared with other hormonal contraceptives, in a study published in JAMA.
A national health database analysis headed by Amani Meaidi, MD, PhD, of the Danish Cancer Society Research Center, Cancer Surveillance and Pharmacoepidemiology, in Copenhagen, compared the 13.5-mg with the 19.5-mg and 52-mg dosages of levonorgestrel-releasing intrauterine systems (IUSs).
The hormone content in levonorgestrel-releasing IUSs must be high enough to maintain optimal contraceptive effect but sufficiently low to minimize progestin-related adverse events, Dr. Meaidi and colleagues noted; they advised using the middle dosage of 19.5 mg. All dosages are recommended for contraception, with the highest dosage also recommended for heavy menstrual bleeding.
“If 10,000 women using the hormonal IUD for 1 year were given the 19.5-mg hormonal IUD instead of the 13.5-mg hormonal IUD, around nine ectopic pregnancies would be avoided,” Dr. Meaidi said in an interview.
“Ectopic pregnancy is an acknowledged adverse event of hormonal IUD use. Although a rare event, it is a serious one, and a difference in ectopic pregnancy safety between the two low-dose hormonal IUDs would impact my recommendations to women.”
The study
Dr. Meaidi’s group followed 963,964 women for 7.8 million person-years. For users of levonorgestrel IUS dosages 52 mg, 19.5 mg, and 13.5 mg, and other hormonal contraceptives, the median ages were 24, 22, 22, and 21 years, respectively.
Eligible women were nulliparous with no previous ectopic pregnancy, abdominal or pelvic surgery, infertility treatment, endometriosis, or use of a levonorgestrel IUS. They were followed from Jan. 1, 2001, or their 15th birthday, until July 1, 2021, age 35, pregnancy, death, emigration, or the occurrence of any exclusion criterion.
During the study period, the cohort registered 2,925 ectopic pregnancies, including 35 at 52 mg, 32 at 19.5 mg, and 80 at 13.5 mg of levonorgestrel. For all other types of hormonal contraception, there were 763 ectopic pregnancies.
In terms of adjusted absolute rates of ectopic pregnancy per 10,000 person-years, compared with other hormonal contraceptives (rate = 2.4), these were 7.7 with 52 mg levonorgestrel IUS, 7.1 with 19.5 mg, and 15.7 with 13.5 mg. They translated to comparative differences of 5.3 (95% confidence interval, 1.9-8.7), 4.8 (95% CI, 1.5-8.0), and 13.4 (95% CI, 8.8-18.1), respectively.
Corresponding adjusted relative rate ratios were 3.4, 4.1, and 7.9. For each levonorgestrel IUS dosage; the ectopic pregnancy rate increased with duration of use.
The adjusted ectopic pregnancy rate difference per 10,000 person-years between the 19.5-mg and 52-mg levonorgestrel dosages was −0.6 , and between the 13.5-mg and 52-mg doses, 8.0, with a rate ratio of 2.3. The rate difference between the 13.5-mg and 19.5-mg levonorgestrel IUS was 8.6, with a rate ratio of 1.9.
An outsider’s perspective
Offering an outsider’s perspective on the study, Eran Bornstein, MD, vice-chair of obstetrics and gynecology at Lenox Hill Hospital in New York, said these data should spark further evaluation of risk of ectopic pregnancy with levonorgestrel-releasing IUDs. “The best advice for clinicians is to individualize the choice of which contraceptive to use, and when levonorgestrel IUD is selected, to individualize the appropriate dose and timing of placement,” he said in an interview.
Several additional factors may determine the best choice, Dr. Bornstein added, including medical conditions that contraindicate other contraceptives and those conditions that justify avoidance of pregnancy, as well as uterine myomas or malformation, the ability of the patient to comply with other options, and informed patient choice. “It is important to remember the potential risk for expulsion and ectopic pregnancy, maintain alertness, and use ultrasound to exclude these potential complications if suspected,” he said.
Dr. Meaidi said the mechanism of ectopic pregnancy with hormonal IUDs is unclear, but in vitro and animal studies have observed that levonorgestrel reduces the ciliary beat frequency in the fallopian tubes. “Thus, it could be hypothesized that if a woman was unfortunate enough to become pregnant using a hormonal IUD, the hormone could inhibit or slow down the movement of the zygote into the uterus for rightful intrauterine implantation and thereby increase the risk of ectopic pregnancy.”
Two coauthors of the study reported financial support from private-sector companies. Dr. Meaidi had no conflicts of interest. Dr. Bornstein disclosed no competing interests.

Neonatal bilirubin meters need better accuracy
Despite their convenience and low cost, , a systematic review and meta-analysis reports in JAMA Pediatrics. Lauren E.H. Westenberg, MD, of the division of neonatology at Erasmus MC Sophia Children’s Hospital in Rotterdam, the Netherlands, and colleagues reported that POC meters tended to underestimate neonatal bilirubin levels, compared with conventional laboratory-based quantification.
Furthermore, pooled estimates from 10 studies found these devices to be too imprecise overall, with substantial outer-confidence bounds. On the plus side, Dr. Westenberg’s group said POC bilirubin testing was as much as 60 times faster than lab measurement, and used 40-60 times less blood. “Conventional laboratory-based bilirubin quantification usually requires up to 500 mcL, but sometimes even 1,500 mcL, while POC tests require up to 50 mcL, which means less stress for the baby,” Dr. Westenberg said in an interview. “Especially when infants are cared for at home, it usually takes a few hours between deciding to quantify bilirubin and obtaining the test result. Meanwhile, bilirubin levels may rise unnoticed.”
On the positive side, POC devices are useful where laboratories in low-resource areas may be remote, poorly equipped, and not always able to provide an accurate bilirubin level. “As a result, the diagnosis of jaundice relies mainly on visual inspection, which is known to be unreliable,” she said. POC devices, however, need near-perfect conditions for optimal use, and results can be affected by humidity, preanalytic conditions such as test strip saturation, and hematocrit.
Yet results from these devices have recently proven to have acceptable accuracy, resulting, for example, in the same clinical decisions as the reference standard in 90.7% of times according to a 2022 study in a hospital in Malawi.
Nevertheless, the authors concluded that the devices’ imprecision limits their widespread use in neonatal jaundice management, especially when accurate lab-based bilirubin quantification is available. Results from these POC tests should be interpreted with caution, Dr. Westenberg said. In terms of clinical decision-making, POC devices entail a risk of missing neonates with jaundice who need phototherapy or, in the case of overestimation, of starting phototherapy too early.
The study
The meta-analysis included nine cross-sectional and one prospective cohort study representing 3,122 neonates in Europe, Africa, and East and Southeast Asia. Two tests with 30-minute turnaround times were evaluated in neonates 0-28 days old. The Bilistick device was evaluated in eight studies and the BiliSpec (now called BiliDX) in just two studies. Three of the studies had a high risk of bias.
A total of 3,122 measurements paired with lab quantification showed a pooled mean difference in total bilirubin levels for the POC devices of –14 micromol/L, with pooled 95% confidence bounds (CBs) of –106 to 78 micromol/L. For the Bilistick, the pooled mean difference was –17 micromol/L (95% CBs, –114 to 80 micromol/L). Of the two devices, the Bilistick was more likely to have a failed quantification against the reference standard.
Context for POC devices
Commenting on the meta-analysis but not involved in it, Rebecca Richards-Kortum, PhD, a professor of biomedical engineering at Rice University in Houston, noted that both devices were developed specifically to address needs in low-resource settings. “I don’t think the meta-analysis acknowledges this rationale sufficiently,” she said. “It feels like this paper is comparing apples to oranges and then criticizing the apples for not being oranges,” said Dr. Richards-Kortum, who helped develop the BiliSpec test.
Similarly, Anne S. Lee, MD, MPH, an associate professor of pediatrics at Brigham and Women’s Hospital in Boston, and not a participant in the meta-analysis, also stressed that POC devices are designed for scenarios where lab-based results are not widely available. “In a broad sense, the devices fill an important gap, both in low- and middle-income countries, as well as in the U.S. when laboratory capacity is not readily available,” said Dr. Lee. She was involved the development of the Bili-ruler icterometer, which proved to be diagnostically accurate in Bangladeshi newborns.
“Access to this technology is a critical way to address health disparities even in the U.S.,” Dr. Lee continued. “We have heard of the need for this technology from the Indian health services and Alaskan health services, where decisions are made to airlift a child based on a visual inspection alone.”
More broadly, however, cautioned Dr. Westenberg, the total allowable error and the permissible limits of uncertainty in neonatal bilirubin quantification need to be defined – irrespective of the method used. “Accurate measurement of bilirubin is difficult as has been demonstrated in so-called external quality assessment (EQA) programs that exist for laboratory-based bilirubin methods,” she said. “EQA programs for POC bilirubin devices that include a reference method as a gold standard may contribute to adaptation of the device and improving POC test imprecision.”
This work was supported by the Netherlands Organization for Health Research and Development. The authors had no conflicts of interest to disclose. Dr. Richards-Kortum and Dr. Lee have both been involved in the development of POC devices for assessing neonatal bilirubin levels.
Despite their convenience and low cost, , a systematic review and meta-analysis reports in JAMA Pediatrics. Lauren E.H. Westenberg, MD, of the division of neonatology at Erasmus MC Sophia Children’s Hospital in Rotterdam, the Netherlands, and colleagues reported that POC meters tended to underestimate neonatal bilirubin levels, compared with conventional laboratory-based quantification.
Furthermore, pooled estimates from 10 studies found these devices to be too imprecise overall, with substantial outer-confidence bounds. On the plus side, Dr. Westenberg’s group said POC bilirubin testing was as much as 60 times faster than lab measurement, and used 40-60 times less blood. “Conventional laboratory-based bilirubin quantification usually requires up to 500 mcL, but sometimes even 1,500 mcL, while POC tests require up to 50 mcL, which means less stress for the baby,” Dr. Westenberg said in an interview. “Especially when infants are cared for at home, it usually takes a few hours between deciding to quantify bilirubin and obtaining the test result. Meanwhile, bilirubin levels may rise unnoticed.”
On the positive side, POC devices are useful where laboratories in low-resource areas may be remote, poorly equipped, and not always able to provide an accurate bilirubin level. “As a result, the diagnosis of jaundice relies mainly on visual inspection, which is known to be unreliable,” she said. POC devices, however, need near-perfect conditions for optimal use, and results can be affected by humidity, preanalytic conditions such as test strip saturation, and hematocrit.
Yet results from these devices have recently proven to have acceptable accuracy, resulting, for example, in the same clinical decisions as the reference standard in 90.7% of times according to a 2022 study in a hospital in Malawi.
Nevertheless, the authors concluded that the devices’ imprecision limits their widespread use in neonatal jaundice management, especially when accurate lab-based bilirubin quantification is available. Results from these POC tests should be interpreted with caution, Dr. Westenberg said. In terms of clinical decision-making, POC devices entail a risk of missing neonates with jaundice who need phototherapy or, in the case of overestimation, of starting phototherapy too early.
The study
The meta-analysis included nine cross-sectional and one prospective cohort study representing 3,122 neonates in Europe, Africa, and East and Southeast Asia. Two tests with 30-minute turnaround times were evaluated in neonates 0-28 days old. The Bilistick device was evaluated in eight studies and the BiliSpec (now called BiliDX) in just two studies. Three of the studies had a high risk of bias.

JAMA PEDIATRICS
Human and nonhuman milk products have similar effect on preemies’ gut microbiota
No significant differences emerged in gut microbial diversity in preterm infants who exclusively received human milk products, compared with those receiving bovine milk formula or fortifiers, a randomized controlled trial found. Nor were any differences noted in the secondary endpoint of clinical outcomes in the U.K. study, published online in JAMA Network Open.
The finding was unanticipated, according to lead author Nicholas D. Embleton, MBBS, MD, a professor of neonatal medicine at Newcastle University in England. “Over the last 10 years we’ve focused particularly on the role of the microbiome to better understand causal mechanisms of necrotizing enterocolitis, or NEC,” he said in an interview. “We anticipated that an exclusive human milk diet would have measurable impacts on microbiome diversity as a potential mechanism [in] disease modulation as part of the mechanism by which exclusive human milk diets benefit preterm infants.”
Shortfalls in a mother’s own milk supply often necessitate the use of bovine formula or pasteurized human milk from donor milk banks or commercial suppliers.
The effect of an exclusive human milk diet versus one containing bovine products on vulnerable preterm infants is unclear, but some studies have shown lower rates of key neonatal morbidities, possibly mediated by the gut microbiome. In two randomized controlled trials, for example, one showed a lower rate of NEC with donated human milk while the other showed no difference.
Neither, however, was powered to detect a clinically important difference in surgical NEC.
Milk and the microbiome
The current study’s primary endpoint was the effect of an exclusive human milk diet on gut bacterial richness and diversity, as well as the proportions of specific microbial taxa in preterm infants from enrollment to 34 weeks’ postmenstrual age.
Conducted at four neonatal intensive care units in the United Kingdom from 2017 to 2020, the study recruited 126 infants born at less than 30 weeks’ gestation and fed exclusively with their own mother’s milk before 72 hours of age. With a median gestational age of 27 weeks and a median birth weight of just over 900 grams, the babies were randomized 1:1 either to their own mother’s milk plus a pasteurized ready-to-feed human milk product or to their mother’s milk plus a standard preterm formula (controls). Stool samples were collected to analyze intestinal microbiota.
In terms of clinical outcomes, four infants died in the standard-care control group and eight in the intervention group at a median postnatal age of 25 days and 15 days, respectively, but none died primarily of NEC. Formula and ready-to-feed human milk both represented less than 1% of all fluid intake, respectively.
Although there were no effects on overall measures of gut bacterial diversity, there were some insignificant effects on specific bacterial taxa previously associated with human milk feeding. “These findings suggest that the clinical impact of human milk-derived products is not modulated via microbiomic mechanisms,” the authors wrote.
Human milk could benefit, however, via components such as specific oligosaccharides, which act largely by modulating the growth of friendly Bifidobacteria and other species, Dr. Embleton said. “However, it’s possible these oligosaccharides might also directly interact via the gut epithelium as a signaling molecule. And, of course, there are many other components that might also act directly on the gut without changing the microbiome.”
*Commenting on the study but not involved in it, Brenda L. Poindexter, MD, MS, chief of the division of neonatology at Children’s Healthcare of Atlanta and Emory University, called it “incredibly important,” especially in the context of the claims of superiority made by the manufacturers of human-milk-based fortifiers. “These findings convincingly debunk the notion that the use of bovine-derived fortifiers increases risk of morbidities such as NEC through the mechanism of alterations in the microbiome, Dr. Poindexter said.
“They refute that claim as there was no difference in NEC between the groups and, interestingly, no impact on the microbiome. One of the hypothesized mechanisms for those who purport that bovine fortifiers are ‘bad’ is that they alter the microbiome, which increases risk of NEC,” she said. “The only limitation is that the study was not powered to detect a difference in NEC, but it is incredibly important nonetheless.”
The current findings differ somewhat from those of a similar trial from 2022 showing lower microbial diversity and higher relative abundances of Enterobacteriaceae and lower abundances of Clostridium sensu stricto in preterm infants receiving an exclusive human milk diet. “These results highlight how nutrient fortifiers impact the microbiota of very-low-birth-weight infants during a critical developmental window,” the authors wrote.
Dr. Embleton conceded that his group’s study set the bar deliberately high to avoid finding too many differences purely due to chance, and it therefore might have missed bacterial changes present in low proportions. “Also, the technique we used, 16s rRNA, doesn’t explore the microbiome at the strain level, so there may have been changes we didn’t detect.”
He added that the study populations also had a relatively high usage of mother’s own milk and findings may differ in other populations and settings where the use of mother’s own milk is much lower. Furthermore, the differences reported by individual hospitals in the babies’ gut microbiomes were more significant than most feeding interventions.
So can mothers needing to use nonhuman supplements be reassured by the results? “It is difficult to know how parents may interpret our findings. We need more studies powered to detect differences in functional outcomes before we can draw conclusions and share those findings in a way parents can understand,” Dr. Embleton said. “At present, there is perhaps a too simplistic message that cow milk formula is ‘harmful.’ ”
Most babies exposed to cow’s milk fortifier or formula do not develop NEC, and many with NEC have only ever received their own mother’s milk or donor milk, he added. “It could be that with advances in pasteurization or other similar techniques the quality and therefore the functional benefits of human milk can be better preserved.”
More research is needed on the mechanisms of preterm feeding interventions, including donor human milk, fortifiers, and probiotics, Dr. Embleton said. “The gut microbiome in preterm infants is complex and very different from that in term infants.”
The study was sponsored by Newcastle Hospitals NHS Foundation Trust and funded by Prolacta Biosciences, which provided human milk formula and fortifier. Dr. Embleton reported financial ties to Danone Early Life Nutrition, Nestlé Nutrition Institute Lecture, Astarte Lecture, and NeoKare outside of the submitted work. Several coauthors reported similar ties to multiple private companies and various research funding bodies. Dr. Poindexter has no conflicts of interest.

FROM JAMA NETWORK OPEN
AAP approves 2023 child and adolescent immunization schedule
The American Academy of Pediatrics said it supports the Recommended Childhood and Adolescent Immunization Schedule: United States, 2023.
In a policy statement published online in the journal Pediatrics, the AAP said the updated recommendations do not include major changes from those released in 2022 by the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention.
In one small shift, COVID-19 is now addressed in the main text instead of being relegated to the notes section.
“And a new vaccine – Priorix [GlaxoSmithKline] – has been added for MMR [measles, mumps, rubella], so now there are two available,” Sean T. O’Leary, MD, MPH, chair of the AAP’s Committee on Infectious Diseases, told this news organization. “There’s also a second pneumococcal conjugate vaccine listed, PCV15, and this and PCV13 can essentially be used interchangeably.”
Minor updates to the schedule, reflected on the cover page, relate to vaccines for COVID-19, dengue fever, and pneumococcal disease, added Dr. O’Leary, a professor of pediatrics at the University of Colorado Anschutz Medical Campus and Children’s Hospital Colorado, Aurora.
The committee also changed layouts to improve the usability of the schedule. Updated annually, the guidance provides a table on recommended pediatric immunizations from birth to age 18 years, and catch-up recommendations for children aged 4 months to 18 years who start their vaccinations late or are more than 1 month behind the recommended age for vaccine administration.
“We hope this annual update will encourage clinicians to make sure all their patients are up to date on their routine vaccinations,” Dr. O’Leary said. “It’s an opportunity to develop strategies to improve vaccination rates.”
The 2023 schedule follows news from the CDC that kindergarten vaccination rates declined during the 2021-2022 school year. Only 93% of kindergarteners obtained full vaccinations, representing a drop of 1 percentage point from the year before and 2 percentage points from the 2019-2020 school year.
The dip in coverage has been attributed to disruptions caused by the COVID-19 pandemic. AAP advises health care professionals to urge families to make sure their child’s vaccines are current.
Among other additions:
In Table 1
- MMR: Second vaccine added (Priorix, GlaxoSmithKline Biologicals)
- Pneumococcal disease: second conjugate vaccine, PCV15, added (Vaxneuvance, Merck Sharp & Dohme).
- COVID-19: New row added.
- Dengue: Text changed from “Seropositive in endemic areas only” to “Seropositive in endemic dengue areas.”
- Inactivated polio vaccine: “See Notes” added to the column for children aged 18 years.
In Table 2
- PCV: Dose 3 to dose 4 interval revised to align with ACIP’s recommendation for dose 4. This dose is necessary only for children ages 12-59 months regardless of risk, or age 60-71 months with any risk who received three doses before age 12 months.
A parent-friendly vaccine schedule for children and adolescents is available on the CDC’s website.
“Vaccines are essential for the health of our whole society, including children and adolescents,” Dr. O’Leary said in a press release from AAP. “These schedules provide a road map [that] parents and pediatricians can follow to help children get the vaccines they need so their immune systems will be ready to recognize and resist diseases.”
As previously, the 2023 schedule was adjusted to ensure consistency between the formats of the childhood/adolescent and adult immunization guidance. A meeting of stakeholder organizations in October 2022 harmonized the two formats.

The American Academy of Pediatrics said it supports the Recommended Childhood and Adolescent Immunization Schedule: United States, 2023.
In a policy statement published online in the journal Pediatrics, the AAP said the updated recommendations do not include major changes from those released in 2022 by the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention.
In one small shift, COVID-19 is now addressed in the main text instead of being relegated to the notes section.
“And a new vaccine – Priorix [GlaxoSmithKline] – has been added for MMR [measles, mumps, rubella], so now there are two available,” Sean T. O’Leary, MD, MPH, chair of the AAP’s Committee on Infectious Diseases, told this news organization. “There’s also a second pneumococcal conjugate vaccine listed, PCV15, and this and PCV13 can essentially be used interchangeably.”
Minor updates to the schedule, reflected on the cover page, relate to vaccines for COVID-19, dengue fever, and pneumococcal disease, added Dr. O’Leary, a professor of pediatrics at the University of Colorado Anschutz Medical Campus and Children’s Hospital Colorado, Aurora.
The committee also changed layouts to improve the usability of the schedule. Updated annually, the guidance provides a table on recommended pediatric immunizations from birth to age 18 years, and catch-up recommendations for children aged 4 months to 18 years who start their vaccinations late or are more than 1 month behind the recommended age for vaccine administration.
“We hope this annual update will encourage clinicians to make sure all their patients are up to date on their routine vaccinations,” Dr. O’Leary said. “It’s an opportunity to develop strategies to improve vaccination rates.”
The 2023 schedule follows news from the CDC that kindergarten vaccination rates declined during the 2021-2022 school year. Only 93% of kindergarteners obtained full vaccinations, representing a drop of 1 percentage point from the year before and 2 percentage points from the 2019-2020 school year.
The dip in coverage has been attributed to disruptions caused by the COVID-19 pandemic. AAP advises health care professionals to urge families to make sure their child’s vaccines are current.
Among other additions:

FROM PEDIATRICS
Children with autism but no intellectual disability may be falling through the cracks
Approximately two out of three children with autism spectrum disorder (ASD) do not have concurrent intellectual disability, according to a population study of ASD trends.
Intellectual functioning remains the best predictor of functional outcomes in kids with ASD, and missing those with no cognitive impairment (ASD-N) can prevent intervention and affect future achievement.
Furthermore, while the study found that ASD-N increased among all demographic subgroups from 2000 to 2016, it also observed widespread health disparities in identifying ASD-N, especially in Black, Hispanic, and underprivileged children.
“ASD is a major public health concern and prevalence estimates are likely to continue to rise as disparities are reduced and ASD identification is improved,” wrote researchers led by Josephine Shenouda, DrPH, MS, of Rutgers School of Public Health in Piscataway, N.J., in Pediatrics .
The study period saw a surprising 500% increase in the prevalence of ASD-N and a 200% increase in the prevalence of cognitive impairment–associated ASD-I , with higher rates across all sex, race, ethnicity, and socioeconomic subgroups. The five- and twofold respective increases are consistent with previous research.
“To a large degree, the rise in autism estimates has been driven by individuals without intellectual disability,” Dr. Shenouda said in an interview. “The best way to address increasing autism and to affect disparities in autism identification is through universal autism screening during the toddler period. And different metrics of functional outcomes need to be developed to understand the expression of autism better.”
Her group had previously seen autism estimates of approximately 1% in 2000 rise to 3% by 2016 but had noted variations, with some communities exceeding 5% for autism estimates. “That led to the question of why, and we saw that in areas with high estimates, we are identifying more children with autism without intellectual disability,” she said. “We wanted to know if the increase over time was equally distributed among children with autism with and without intellectual disability.”
A study in disparities
The cross-sectional study examined data from active ASD surveillance by the CDC’s Autism and Developmental Disabilities Monitoring Network in 8-year-olds residing in the New York/New Jersey Metropolitan Area. Overall, 4,661 children were identified with ASD, with ASD-I affecting 1,505 (32.3%), and ASD-N affecting 2,764 (59.3%). Non-Hispanic Black children who were affected numbered 946 (20.3%), while 1,230 (26.4%) were Hispanic, and 2,114 (45.4%) were non-Hispanic White.
Notably, Black children were 30% less likely to be identified with ASD-N compared with White children, and children residing in affluent areas were 80% more likely to be identified with ASD-N versus those in underserved areas. Furthermore, a greater proportion of children with ASD-I resided in vulnerable areas compared with their counterparts with ASD-N.
While males had a higher prevalence compared with females regardless of intellectual disability status, male-to-female ratios were slightly lower among ASD-I compared with ASD-N cases.
Commenting on the study but not involved in it, Barbara J. Howard, MD, an assistant professor of medicine at Johns Hopkins University, Baltimore, said the increasing gap in identifying ASD-N according to race, ethnicity, and socioeconomic status measures probably reflects greater parental awareness of ASD and access to diagnostic services in White families and those of higher socioeconomic status. “There were no racial, ethnicity, or socioeconomic status differences in the prevalence of the more obvious and impairing ASD-I in the sample, but its prevalence was also increasing over this period,” she said.
Although the greater recognition of the less impairing ASD-N is important for optimal outcomes through intervention, the increasing discrepancies mean that more children generally and more marginalized children specifically are not being diagnosed or served. “There should be no differences in prevalence by these characteristics,” Dr. Howard said. “The striking inequity for non-White children and those of lower socioeconomic status in being diagnosed with ASD-N and thus qualifying for intervention that could improve their long-term functioning is likely also compounded by service, educational, and social disadvantages they may experience.”
In light of these disparities, an accompanying editorial by Emily Hotez, PhD, of the University of California, Los Angeles, and Lindsay Shea, DrPH, of the A.J. Drexel Autism Institute at Drexel University, Philadelphia, argues that social determinants of health (SDOH) should be prioritized in the public health surveillance of autism since these factors potentially contribute to the general underdiagnosis of autism in minority groups and merit more attention from pediatricians. While SDOH affects many nonautistic conditions, it may be even more important for families dealing with the stressors and isolation associated with autism, the commentators said. “Our commentary speaks to the utility of increasing SDOH surveillance in improving our understanding of autistic individuals’ needs, experiences, and priorities on a population level,” Dr. Hotez said in an interview. She added that integrating SDOH surveillance into pediatricians’ workflows will lead to improvements in clinical practice and patient care in the long term.
“Specifically, increased uptake of universal SDOH screening and referral practices will allow pediatricians to more proactively link autistic children and families, particularly those from marginalized groups, with much-needed health-promoting services and supports.” She cautioned, however, that while most providers believe universal SDOH screening is important, fewer report that screening is feasible or feel prepared to address families’ social needs when they are identified.
This study was supported by the Centers for Disease Control and Prevention and the National Institutes of Health/National Institute of Environmental Health Sciences. The authors had no conflicts of interest to disclose. The commentators had no potential conflicts of interest to disclose. Dr. Howard disclosed no competing interests relevant to her comments.

FROM PEDIATRICS
Surgeon gender not associated with maternal morbidity and hemorrhage after C-section
Surgeon gender was not associated with maternal morbidity or severe blood loss after cesarean delivery, a large prospective cohort study from France reports. The results have important implications for the promotion of gender equality among surgeons, obstetricians in particular, wrote a team led by Hanane Bouchghoul, MD, PhD, of the department of obstetrics and gynecology at Bordeaux (France) University Hospital. The report is in JAMA Surgery.
“Our findings are significant in that they add substantially to the string of studies contradicting the age-old dogma that men are better surgeons than women,” the authors wrote. Previous research has suggested slightly better outcomes with female surgeons or higher complication rates with male surgeons.
The results support those of a recent Canadian retrospective analysis suggesting that patients treated by male or female surgeons for various elective indications experience similar surgical outcomes but with a slight, statistically significant decrease in 30-day mortality when treated by female surgeons.
“Policy makers need to combat prejudice against women in surgical careers, particularly in obstetrics and gynecology, so that women no longer experience conscious or unconscious barriers or difficulties in their professional choices, training, and relationships with colleagues or patients,” study corresponding author Loïc Sentilhes, MD, PhD, of Bordeaux University Hospital, said in an interview.
Facing such barriers, women may doubt their ability to be surgeons, their legitimacy as surgeons, and may not consider this type of career, he continued. “Moreover a teacher may not be as involved in teaching young female surgeons as young male surgeons, or the doctor-patient relationship may be more complicated in the event of complications if the patient thinks that a female surgeon has less competence than a male surgeon.”
The analysis drew on data from the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery 2 trial, a multicenter, randomized, placebo-controlled study conducted from March 2018 through January 2020 in mothers from 27 French maternity hospitals.
Eligible participants had a cesarean delivery before or during labor at or after 34 weeks’ gestation. The primary endpoint was the incidence of a composite maternal morbidity variable, and the secondary endpoint was the incidence of postpartum hemorrhage, defined by a calculated estimated blood loss exceeding 1,000 mL or transfusion by day 2.
Among the 4,244 women included, male surgeons performed 943 cesarean deliveries (22.2%) and female surgeons performed 3,301 (77.8%). The percentage who were attending obstetricians was higher for men at 441 of 929 (47.5%) than women at 687 of 3,239 (21.2%).
The observed risk of maternal morbidity did not differ between male and female surgeons: 119 of 837 (14.2%) vs. 476 of 2,928 (16.3%), for an adjusted risk ratio (aRR) of 0.92 (95% confidence interval [CI], 0.77-1.13). Interaction between surgeon gender and level of experience with the risk of maternal morbidity was not statistically significant; nor did the groups differ specifically by risk for postpartum hemorrhage: aRR, 0.98 (95% CI, 0.85-1.13).
Despite the longstanding stereotype that men perform surgery better than women, and the traditional preponderance of male surgeons, the authors noted, postoperative morbidity and mortality may be lower after various surgeries performed by women.
The TRAAP2 trial
In an accompanying editorial, Amanda Fader, MD, of the department of obstetrics and gynecology at Johns Hopkins School of Medicine in Baltimore, and colleagues caution that the French study’s methodology may not fully account for the complex intersection of surgeon volume, experience, gender, clinical decision-making skills, and patient-level and clinical factors affecting outcomes.
That said, appraising surgical outcomes based on gender may be an essential step toward reducing implicit bias and dispelling engendered perceptions regarding gender and technical proficiency, the commentators stated. “To definitively dispel archaic, gender-based notions about performance in clinical or surgical settings, efforts must go beyond peer-reviewed research,” Dr. Fader said in an interview. “Medical institutions and leaders of clinical departments must make concerted efforts to recruit, mentor, support, and promote women and persons of all genders in medicine – as well as confront any discriminatory perceptions and experiences concerning sex, race and ethnicity, sexual orientation, or economic class.”
This study was supported by the French Ministry of Health under its Clinical Research Hospital Program. Dr. Sentilhes reported financial relationships with Dilafor, Bayer, GlaxoSmithKline, Sigvaris, and Ferring Pharmaceuticals. The editorial commentators disclosed no funding for their commentary or conflicts of interest.

Facing such barriers, women may doubt their ability to be surgeons, their legitimacy as surgeons, and may not consider this type of career, he continued. “Moreover a teacher may not be as involved in teaching young female surgeons as young male surgeons, or the doctor-patient relationship may be more complicated in the event of complications if the patient thinks that a female surgeon has less competence than a male surgeon.”
The analysis drew on data from the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery 2 trial, a multicenter, randomized, placebo-controlled study conducted from March 2018 through January 2020 in mothers from 27 French maternity hospitals.
Eligible participants had a cesarean delivery before or during labor at or after 34 weeks’ gestation. The primary endpoint was the incidence of a composite maternal morbidity variable, and the secondary endpoint was the incidence of postpartum hemorrhage, defined by a calculated estimated blood loss exceeding 1,000 mL or transfusion by day 2.
Among the 4,244 women included, male surgeons performed 943 cesarean deliveries (22.2%) and female surgeons performed 3,301 (77.8%). The percentage who were attending obstetricians was higher for men at 441 of 929 (47.5%) than women at 687 of 3,239 (21.2%).
The observed risk of maternal morbidity did not differ between male and female surgeons: 119 of 837 (14.2%) vs. 476 of 2,928 (16.3%), for an adjusted risk ratio (aRR) of 0.92 (95% confidence interval [CI], 0.77-1.13). Interaction between surgeon gender and level of experience with the risk of maternal morbidity was not statistically significant; nor did the groups differ specifically by risk for postpartum hemorrhage: aRR, 0.98 (95% CI, 0.85-1.13).
Despite the longstanding stereotype that men perform surgery better than women, and the traditional preponderance of male surgeons, the authors noted, postoperative morbidity and mortality may be lower after various surgeries performed by women.
The TRAAP2 trial
In an accompanying editorial, Amanda Fader, MD, of the department of obstetrics and gynecology at Johns Hopkins School of Medicine in Baltimore, and colleagues caution that the French study’s methodology may not fully account for the complex intersection of surgeon volume, experience, gender, clinical decision-making skills, and patient-level and clinical factors affecting outcomes.
That said, appraising surgical outcomes based on gender may be an essential step toward reducing implicit bias and dispelling engendered perceptions regarding gender and technical proficiency, the commentators stated. “To definitively dispel archaic, gender-based notions about performance in clinical or surgical settings, efforts must go beyond peer-reviewed research,” Dr. Fader said in an interview. “Medical institutions and leaders of clinical departments must make concerted efforts to recruit, mentor, support, and promote women and persons of all genders in medicine – as well as confront any discriminatory perceptions and experiences concerning sex, race and ethnicity, sexual orientation, or economic class.”
This study was supported by the French Ministry of Health under its Clinical Research Hospital Program. Dr. Sentilhes reported financial relationships with Dilafor, Bayer, GlaxoSmithKline, Sigvaris, and Ferring Pharmaceuticals. The editorial commentators disclosed no funding for their commentary or conflicts of interest.

Ospemifene and HT boost vaginal microbiome in vulvovaginal atrophy
The selective estrogen receptor modulator ospemifene appears to improve the vaginal microbiome of postmenopausal women with vulvovaginal atrophy (VVA), according to results from a small Italian case-control study in the journal Menopause.
The study sheds microbiological light on the mechanisms of ospemifene and low-dose systemic hormone therapy, which are widely used to treat genitourinary symptoms. Both had a positive effect on vaginal well-being, likely by reducing potentially harmful bacteria and increasing health-promoting acid-friendly microorganisms, writes a group led by M. Cristina Meriggiola, MD, PhD, of the gynecology and physiopathology of human reproduction unit at the University of Bologna, Italy.
VVA occurs in about 50% of postmenopausal women and produces a less favorable, less acidic vaginal microbiome profile than that of unaffected women. “The loss of estrogen leads to lower concentrations of Lactobacilli, bacteria that lower the pH. As a result, other bacterial species fill in the void,” explained Stephanie S. Faubion, MD, MBA, director of the Mayo Clinic Center for Women’s Health in Jacksonville, Fla., and medical director of the North American Menopause Society.
Added Tina Murphy, APN, a NAMS-certified menopause practitioner at Northwestern Medicine Orland Park in Illinois, “When this protective flora declines, then pathogenic bacteria can predominate the microbiome, which can contribute to vaginal irritation, infection, UTI’s, dyspareunia, and discomfort. Balancing and restoring the microbiome can mitigate the effects of estrogen depletion on the vaginal tissue and prevent the untoward effects of the hypoestrogenic state.” While ospemifene and hormone therapy are common therapies for the genitourinary symptoms of menopause, the focus has been on their treatment efficacy, not their effect on the microbiome profile, added Dr. Faubion. Only about 9% of women with menopause-related genitourinary symptoms receive prescription treatment, she added.
The study
Of 67 eligible postmenopausal participants in their mid-50s enrolled at a gynecology clinic from April 2019 to February 2020, 39 were diagnosed with VVA and 28 were considered healthy controls. In the atrophic group, 20 were prescribed ospemifene and 19 received hormone treatment.
Only those women with VVA but no menopausal vasomotor symptoms received ospemifene (60 mg/day); symptomatic women received hormone therapy according to guidelines.
The researchers calculated the women’s vaginal health index (VHI) based on elasticity, secretions, pH level, epithelial mucosa, and hydration. They used swabs to assess vaginal maturation index (VMI) by percentages of superficial, intermediate, and parabasal cells. Evaluation of the vaginal microbiome was done with 16S rRNA gene sequencing, and clinical and microbiological analyses were repeated after 3 months.
The vaginal microbiome of atrophic women was characterized by a significant reduction of benign Lactobacillus bacteria (P = .002) and an increase of potentially pathogenic Streptococcus (P = .008) and Sneathia (P = .02) bacteria.
The vaginal microbiome of women with VVA was depleted, within the Lactobacillus genus, in the L. crispatus species, a hallmark of vaginal health that has significant antimicrobial activity against endogenous and exogenous pathogens.
Furthermore, there was a positive correlation between the VHI/VMI and Lactobacillus abundance (P = .002 and P = 0.035, respectively).
While the lactic acid–producing Lactobacillus and Bifidobacterium genera were strongly associated with healthy controls, the characteristics of VVA patients were strongly associated with Streptococcus, Prevotella, Alloscardovia, and Staphylococcus.
Both therapeutic approaches effectively improved vaginal indices but by different routes. Systemic hormone treatment induced changes in minority bacterial groups in the vaginal microbiome, whereas ospemifene eliminated specific harmful bacterial taxa, such as Staphylococcus (P = .04) and Clostridium (P = .01). Both treatments induced a trend in the increase of beneficial Bifidobacteria.
A 2022 study reported that vaginal estradiol tablets significantly changed the vaginal microbiota in postmenopausal women compared with vaginal moisturizer or placebo, but the reductions in bothersome symptoms were similar.
The future
“Areas for future study include the assessment of changes in the vaginal microbiome, proteomic profiles, and immunologic markers with various treatments and the associations between these changes and genitourinary symptoms,” Dr. Faubion said. She added that, while there may be a role at some point for oral or topical probiotics, “Thus far, probiotics have not demonstrated significant benefits.”
Meanwhile, said Ms. Murphy, “There are many options available that may benefit our patients. As a provider, meeting with your patient, discussing her concerns and individual risk factors is the most important part of choosing the correct treatment plan.”
The authors call for further studies to confirm the observed modifications of the vaginal ecosystem. In the meantime, Dr. Meriggiola said in an interview, “My best advice to physicians is to ask women if they have this problem. Do not ignore it; be proactive and treat. There are many options on the market for genitourinary symptoms – not just for postmenopausal women but breast cancer survivors as well.”
Dr. Meriggiola’s group is planning to study ospemifene in cancer patients, whose quality of life is severely affected by VVA.
This study received no financial support. Dr. Meriggiola reported past financial relationships with Shionogi Limited, Teramex, Organon, Italfarmaco, MDS Italia, and Bayer. Coauthor Dr. Baldassarre disclosed past financial relationships with Shionogi. Ms. Murphy disclosed no relevant conflicts of interest with respect to her comments.

State quality initiative can reduce postpartum hemorrhage and maternal morbidity
A statewide quality initiative can improve severe maternal morbidity (SMM) and reduce the incidence of maternal morbidity and mortality from postpartum hemorrhage (PPH), a modeling analysis found. Such measures could potentially provide savings to birthing hospitals, according to the California cost-effectiveness study, published in Obstetrics & Gynecology.
A team led by Eric C. Wiesehan, MHA, MBA, a PhD candidate in health policy at Stanford (Calif.) University, examined the effects of the safety initiative of the California Maternal Quality Care Collaborative (CMQCC) in a theoretical cohort of 480,000 births across a mix of hospital settings and sizes. The CMQCC developed a PPH toolkit and quality-improvement protocol to increase recognition, measurement, and timely response to PPH.
Drawing retrospectively on a large 2017 California implementation study, the simulation estimated that collaborative implementation of the CMQCC added 182 quality-adjusted life-years (0.000379 per birth) by averting 913 cases of SMM, 28 emergency hysterectomies, and one maternal mortality. Additionally, it saved $9 million ($17.78 per birth) owing to avoided SMM costs.
According to the Centers for Disease Control and Prevention, pregnancy-related maternal deaths in the United States have increased from 7.2 per 100,000 live births to 16.9 per 100,000 live births over the past 20 years, making it the only country in the Organization for Economic Cooperation and Development with rising rates of maternal mortality. PPH accounts for 11% of maternal deaths.
As to the study’s broader applicability, Dr. Wiesehan said in an interview, “findings of effectiveness in terms of reducing PPH-related SMM are well known outside of California. In terms of costs, however, it is more of an unknown how much is generalizable. It would go a long way if another state quality care collaborative implementing such a project recorded costs prospectively. Prospective costing, particularly microcosting, would be optimal to precisely place where the most, or least, value of this quality improvement project is achieved.”
Studies of PPH safety programs in other U.S. jurisdictions showing reductions in blood transfusions and maternal morbidities suggest the current findings are relevant to a range of hospital settings and regions. “With state perinatal collaboratives already in 47 states, examination of implementation of the PPH-SMM reduction initiative within additional collaboratives would add further robustness to our findings,” the authors wrote.
In 2022, a New York City hospital study reported that learning collaboratives that optimize practice and raise staff awareness could be important tools for improving maternal outcomes.
Still to be answered, said Dr. Wiesehan, are questions about the long-term effectiveness and sustainability of the quality initiative project beyond the early pre/post periods.
The authors indicated no specific funding for the study and had no conflicts of interest to disclose.

Abnormal bleeding common among youth with joint hypermobility
A small cohort study of pediatric rheumatology patients with generalized joint hypermobility (GJH) who presented to a specialized rheumatology* clinic suggests that many such patients have abnormal bleeding symptoms, in comparison with health control patients.
The study of 81 patients with GJH found that about three quarters had significantly elevated median bleeding scores, but only 12% had been assessed by hematology for bleeding.
“We propose that screening for bleeding symptoms should be integrated into the routine care for all patients with GJH, with hematology referrals for patients with increased bleeding concerns,” wrote a research team led by Nicole E. Kendel, MD, a pediatric hematologist-oncologist at Akron Children’s Hospital in Ohio, in a study published online in Arthritis Care and Research.
“Further studies are needed to understand the mechanism of bleeding, evaluate comorbidities associated with these bleeding symptoms, and potentially allow for tailored pharmacologic therapy,” the authors stated.
Background
Dr. Kendel’s team had reported moderate menstruation-associated limitations in school, social, and physical activities among female adolescents with GJH. “This cohort also experienced nonreproductive bleeding symptoms and demonstrated minimal hemostatic laboratory abnormalities, indicating that this population may be underdiagnosed and subsequently poorly managed,” she said in an interview. “As excessive bleeding symptoms could have a significant impact on overall health and quality of life, we thought it was important to define the incidence and natural course of bleeding symptoms in a more generalized subset of this population.”
Although the investigators hypothesized that there would be a statistically significant increase in bleeding scores, “we were still impressed by the frequency of abnormal scores, particularly when looking at the low percentage of patients [12%] who had previously been referred to hematology,” she said.
Study results
The median age of the study cohort was 13 years (interquartile range, 10-16 years), and 72.8% were female. The mean Beighton score, which measures joint flexibility, was 6.2 (range, 4-9). All participants were seen by rheumatologists and were diagnosed for conditions on the hypermobility spectrum. Those conditions ranged from GJH to hypermobile Ehlers-Danlos syndrome (hEDS).
Abnormal bleeding, as measured by the International Society on Thrombosis and Haemostasis Bleeding Assessment Tool, was found in 75% (95% confidence interval [CI], 64%-84%). Overall mean and median bleeding scores were 5.2 and 4, respectively; scores ranged from 0 to 16. Abnormal scores of ≥ 3 were observed for patients < 8 years of age, ≥ 4 for men ≥ 18 years of age, and ≥ 6 for women ≥ 18 years of age. These measures were significantly elevated compared with those reported for historical healthy pediatric control persons (P < .001).
The most common hemorrhagic symptom was oral bleeding (74.1%) that occurred with tooth brushing, flossing, tooth loss, or eruption. Others reported easy bruising (59.3%) and bleeding from minor wounds (42%). In terms of procedures, tooth extraction requiring additional packing was reported by 25.9%, and 22.2% reported significant bleeding after otolaryngologic procedures, such as tonsillectomy/adenoidectomy, septoplasty, and nasal turbinate reduction.
Prolonged or heavy menstrual periods were reported by 37.3% of female patients.
Bleeding scores did not differ by biological sex or NSAID use, nor did any correlation emerge between patients’ bleeding and Beighton scores. However, there was a positive correlation with increasing age, a phenomenon observed with other bleeding disorders and in the healthy population, the authors noted.
Of the 10 study participants who had previously undergone hematologic assessment, one had been diagnosed with acquired, heart disease–related von Willebrand disease, and another with mild bleeding disorder.
Severe connective tissue disorders are associated with increased bleeding symptoms in the adult population, Dr. Kendel said, but few studies have assessed bleeding across the GJH spectrum, particularly in children.
Bleeding is thought to be due to modifications of collagen in the blood vessels. “These modifications create mechanical weakness of the vessel wall, as well as defective subendothelial connective tissue supporting those blood vessels,” Dr. Kendel explained. She noted that altered collagen creates defective interactions between collagen and other coagulation factors.
“Even in the presence of a normal laboratory evaluation, GJH can lead to symptoms consistent with a mild bleeding disorder,” she continued. “These symptoms are both preventable and treatable. I’m hopeful more centers will start routinely evaluating for increased bleeding symptoms, with referral to hematology for those with increased bleeding concerns.”
Commenting on the study’s recommendation, Beth S. Gottlieb, MD, chief of the division of pediatric rheumatology at Northwell Health in New Hyde Park, N.Y., who was not involved in the investigation, said a brief questionnaire on bleeding risk is a reasonable addition to a rheumatology office visit.
“Joint hypermobility is very common, but not all affected children meet the criteria for the hypermobile form of hEDS,” she told this news organization. “Screening for bleeding tendency is often done as routine medical history questions. Once a child is identified as hypermobile, these screening questions are usually asked, but utilizing one of the formal bleeding risk questionnaires is not currently routine.”
According to Dr. Gottlieb, it remains unclear whether screening would have a significant impact on children who have been diagnosed with hypermobility. “Most of these children are young and may not yet have a significant history for bleeding tendency,” she said. “Education of families is always important, and it will be essential to educate without adding unnecessary stress. Screening guidelines may be an important tool that is easy to incorporate into routine clinical practice.”
Limitation
The study was limited by selection bias, as patients had all been referred to a specialized rheumatology clinic.
The study was supported by the Clinical and Translational Intramural Funding Program of the Abigail Wexner Research Institute. The authors and Dr. Gottlieb have disclosed no relevant financial relationships.

A small cohort study of pediatric rheumatology patients with generalized joint hypermobility (GJH) who presented to a specialized rheumatology* clinic suggests that many such patients have abnormal bleeding symptoms, in comparison with health control patients.
The study of 81 patients with GJH found that about three quarters had significantly elevated median bleeding scores, but only 12% had been assessed by hematology for bleeding.
“We propose that screening for bleeding symptoms should be integrated into the routine care for all patients with GJH, with hematology referrals for patients with increased bleeding concerns,” wrote a research team led by Nicole E. Kendel, MD, a pediatric hematologist-oncologist at Akron Children’s Hospital in Ohio, in a study published online in Arthritis Care and Research.
“Further studies are needed to understand the mechanism of bleeding, evaluate comorbidities associated with these bleeding symptoms, and potentially allow for tailored pharmacologic therapy,” the authors stated.
Background
Dr. Kendel’s team had reported moderate menstruation-associated limitations in school, social, and physical activities among female adolescents with GJH. “This cohort also experienced nonreproductive bleeding symptoms and demonstrated minimal hemostatic laboratory abnormalities, indicating that this population may be underdiagnosed and subsequently poorly managed,” she said in an interview. “As excessive bleeding symptoms could have a significant impact on overall health and quality of life, we thought it was important to define the incidence and natural course of bleeding symptoms in a more generalized subset of this population.”
Although the investigators hypothesized that there would be a statistically significant increase in bleeding scores, “we were still impressed by the frequency of abnormal scores, particularly when looking at the low percentage of patients [12%] who had previously been referred to hematology,” she said.
Study results
The median age of the study cohort was 13 years (interquartile range, 10-16 years), and 72.8% were female. The mean Beighton score, which measures joint flexibility, was 6.2 (range, 4-9). All participants were seen by rheumatologists and were diagnosed for conditions on the hypermobility spectrum. Those conditions ranged from GJH to hypermobile Ehlers-Danlos syndrome (hEDS).
Abnormal bleeding, as measured by the International Society on Thrombosis and Haemostasis Bleeding Assessment Tool, was found in 75% (95% confidence interval [CI], 64%-84%). Overall mean and median bleeding scores were 5.2 and 4, respectively; scores ranged from 0 to 16. Abnormal scores of ≥ 3 were observed for patients < 8 years of age, ≥ 4 for men ≥ 18 years of age, and ≥ 6 for women ≥ 18 years of age. These measures were significantly elevated compared with those reported for historical healthy pediatric control persons (P < .001).
The most common hemorrhagic symptom was oral bleeding (74.1%) that occurred with tooth brushing, flossing, tooth loss, or eruption. Others reported easy bruising (59.3%) and bleeding from minor wounds (42%). In terms of procedures, tooth extraction requiring additional packing was reported by 25.9%, and 22.2% reported significant bleeding after otolaryngologic procedures, such as tonsillectomy/adenoidectomy, septoplasty, and nasal turbinate reduction.
Prolonged or heavy menstrual periods were reported by 37.3% of female patients.
Bleeding scores did not differ by biological sex or NSAID use, nor did any correlation emerge between patients’ bleeding and Beighton scores. However, there was a positive correlation with increasing age, a phenomenon observed with other bleeding disorders and in the healthy population, the authors noted.
Of the 10 study participants who had previously undergone hematologic assessment, one had been diagnosed with acquired, heart disease–related von Willebrand disease, and another with mild bleeding disorder.
Severe connective tissue disorders are associated with increased bleeding symptoms in the adult population, Dr. Kendel said, but few studies have assessed bleeding across the GJH spectrum, particularly in children.
Bleeding is thought to be due to modifications of collagen in the blood vessels. “These modifications create mechanical weakness of the vessel wall, as well as defective subendothelial connective tissue supporting those blood vessels,” Dr. Kendel explained. She noted that altered collagen creates defective interactions between collagen and other coagulation factors.
“Even in the presence of a normal laboratory evaluation, GJH can lead to symptoms consistent with a mild bleeding disorder,” she continued. “These symptoms are both preventable and treatable. I’m hopeful more centers will start routinely evaluating for increased bleeding symptoms, with referral to hematology for those with increased bleeding concerns.”
Commenting on the study’s recommendation, Beth S. Gottlieb, MD, chief of the division of pediatric rheumatology at Northwell Health in New Hyde Park, N.Y., who was not involved in the investigation, said a brief questionnaire on bleeding risk is a reasonable addition to a rheumatology office visit.
“Joint hypermobility is very common, but not all affected children meet the criteria for the hypermobile form of hEDS,” she told this news organization. “Screening for bleeding tendency is often done as routine medical history questions. Once a child is identified as hypermobile, these screening questions are usually asked, but utilizing one of the formal bleeding risk questionnaires is not currently routine.”
According to Dr. Gottlieb, it remains unclear whether screening would have a significant impact on children who have been diagnosed with hypermobility. “Most of these children are young and may not yet have a significant history for bleeding tendency,” she said. “Education of families is always important, and it will be essential to educate without adding unnecessary stress. Screening guidelines may be an important tool that is easy to incorporate into routine clinical practice.”
Limitation
The study was limited by selection bias, as patients had all been referred to a specialized rheumatology clinic.
The study was supported by the Clinical and Translational Intramural Funding Program of the Abigail Wexner Research Institute. The authors and Dr. Gottlieb have disclosed no relevant financial relationships.
