Ceftazidime-avibactam was noninferior to meropenem for nosocomial pneumonia including ventilator-associated pneumonia from gram-negative organisms, results from the REPROVE trial demonstrated.

Nosocomial or hospital-acquired pneumonia is a common hospital-acquired infection associated with increased cost and mortality. Further, nosocomial pneumonia is associated with gram-negative pathogens such as Pseudomonas aeruginosa and Enterobacteriaceae that may carry extended-spectrum beta-lactamases and carbapenemase, thereby limiting the treatment options. However, ceftazidime-avibactam has both antipseudomonal and extended beta-lactamase coverage for multidrug-resistant gram-negative infections, and may provide an alternative to meropenem.

Antoni Torres, MD, of the University of Barcelona and his colleagues sought to compare the safety and efficacy of ceftazidime-avibactam to meropenem in patients with nosocomial and ventilator-associated pneumonia. The REPROVE study was a phase 3, double-blind, noninferiority trial performed at 136 centers in 23 countries. Patients were randomly assigned 1:1 to receive either ceftazidime-avibactam (500-2,000 mg every 8 hours) or meropenem (1,000 mg every 8 hours) with adjustment as needed for renal function.

Participants included in the study were 18-90 years of age with nosocomial pneumonia as evidenced by pneumonia 48 hours or more after admission or within 7 days after discharge from an inpatient facility. Patients with ventilator-associated pneumonia had lung infection within 48 hours of intubation and mechanical ventilation. Sputum culture and gram stains were obtained within 48 hours before randomization, and patients were excluded for evidence of gram-positive–only pathogens or those not expected to respond to meropenem or ceftazidime-avibactam.

The study involved a safety population (808 patients), a clinically modified intention-to-treat population (726), and a clinically evaluable population (527). The intention-to-treat population demonstrated a predominance of Klebsiella pneumoniae (37%), and Pseudomonas aeruginosa (30%); 28% of the intention-to-treat population were identified as not susceptible to ceftazidime.

Overall, the clinically modified intention-to-treat group demonstrated a clinical cure rate of 68.8% (245/356) in the ceftazidime-avibactam and 73.0% (270/370) for the meropenem group (difference, –4.2%; 95% confidence interval, –10.8 to 2.5). The evaluable population demonstrated a clinical cure rate of 77.4% (199/257) in the ceftazidime-avibactam group and 78.1% (211/270) in the meropenem group (–0.7%; 95% CI, –7.9 to 6.4).

The all-cause mortality rate was similar between groups at the test-of-cure date and at day 28. The clinically modified intention-to-treat population demonstrated a mortality of 8.1% vs. 6.8% at the test-of-cure date and 8.4% vs. 7.3% at day 28 for ceftazidime-avibactam and meropenem, respectively.

Adverse events were noted in 75% vs. 74% of patients in the ceftazidime-avibactam groups and meropenem groups, respectively. Most adverse events were rated as mild to moderate and deemed likely unrelated to the treatment.

However, serious adverse events occurred in 19% (n = 75) in the ceftazidime-avibactam group and 13% (n = 54) in the meropenem group. Four serious adverse events were thought to be possibly related to the study drug ceftazidime-avibactam and included diarrhea, acute coronary syndrome, subacute hepatic failure, and abnormal liver function test results. The authors noted the adverse events in the trial were consistent and detected no new safety concerns for ceftazidime-avibactam.

Limitations of the study included an inability to establish the optimal duration of treatment for nosocomial pneumonia treated with meropenem or ceftazidime-avibactam.

“Our results show noninferiority for the treatment of nosocomial pneumonia caused by ceftazidime-nonsusceptible or ceftazidime-susceptible gram-negative aerobic pathogens,” the authors concluded.

The study was initially funded by AstraZeneca until the rights to ceftazidime-avibactam were acquired by Pfizer. Multiple authors reported financial relationships with AstraZeneca including grant funding, employment, and shareholding.

New multi-analyte blood test shows promise in screening for several common solid tumors

What are the clinically relevant questions answered by this test?

Imagine a single blood test that would cost less than $500 and could screen for at least eight cancer types.

It’s early days for the technology, called CancerSEEK, but the test had a sensitivity of 69%-98%, depending on the cancer type, and a specificity of 99% in a cohort of 1,005 patients with stage I-III cancers and 850 healthy controls, wrote Joshua D. Cohen of the Ludwig Center for Cancer Genetics and Therapeutics at Johns Hopkins University, Baltimore, and his colleagues. The report was published in Science.

CancerSEEK tests for mutations in 2,001 genomic positions and eight proteins. The researchers examined a 61-amplicon panel with each amplicon analyzing an average of 33 base pairs within a gene. They theorized the test could detect between 41% and 95% of the cancers in the Catalog of Somatic Mutations in Cancer dataset. They next used multiplex-PCR techniques to minimize errors associated with large sequencing and identified protein biomarkers for early stage cancers that may not release detectable ctDNA.

The researchers used the technology to examine blood samples from 1,005 patients with stage I (20%), stage II (49%), or stage III (31%) cancers of the ovary, liver, stomach, pancreas, esophagus, colorectum, lung, or breast prior to undergoing neoadjuvant chemotherapy. Participants had a median age of 64 years (range of 22-93 years). The healthy controls did not have a history of cancer, chronic kidney disease, autoimmune disease, or high-grade dysplasia.

 

 


The sensitivity of the test ranged from 98% in ovarian cancer to 33% in breast cancer, but the specificity was greater than 99% with only 7 of 812 control participants having a positive result. “We could not be certain that the few ‘false positive’ individuals identified among the healthy cohort did not actually have an as-yet undetected cancer, but classifying them as false positives provided the most conservative approach to classification and interpretation of the data,” the authors wrote.

Based on cancer stage, sensitivity for stage I cancers was 43%, for stage II 73%, and for stage III 78%. Again, sensitivity varied depending on cancer type, with 100% sensitivity for stage I liver cancer and 20% sensitivity for stage I esophageal cancer.

When tumor tissue samples from 153 patients with statistically significant ctDNA levels were analyzed, identical mutations were found in the plasma and tumor in 90% (138) of all cases.

The protein markers in the CancerSEEK test might also be able to anatomically locate malignancies. Using machine learning to analyze patients testing positive with CancerSEEK, the results narrowed the source of the cancer to two possible anatomical sites in approximately 83% of patients and to one anatomical site in approximately 63% of patients. Accuracy was highest for colorectal cancer and lowest for lung cancer.
 

 


As the study included otherwise healthy patients with known malignancies, the results need to be confirmed with prospective studies of incidence cancer types in a large population. Patients in the screening setting may have less advanced disease and other comorbidities that could impact the sensitivity and specificity of the CancerSEEK test, the researchers wrote.

The study was funded by multiple sources including grants from the National Institutes of Health. The authors reported various disclosures involving diagnostics and pharmaceutical companies.

Molecular panels are here to stay – and the GI community will in some shape or form be impacted, be it in performing diagnostic procedures on test-positive patients, or risk-stratifying patients prior to testing.

The conceptual challenge is that it is not about what any given test measures – various panels use separate combination of markers from epigenetics to DNA mutations as well as whole or truncated proteins – but how well a specific test with its somewhat arbitrarily chosen components and cutoffs performs. And, more importantly, what the clinical implications of positive or negative test results are. And no one knows that. At least for now.

A recent report in Science from a group from the Ludwig Center for Cancer Genetics at Johns Hopkins proposes a new cancer blood test based on a very systematic and thoughtful approach to include select mutations in cell-free DNA and circulating proteins associated with various solid organ tumors. For validation, they used healthy and advanced but nonmetastatic cancer cohorts. Through stringent controls and a series of validations, the authors present a range of sensitivities for the various cancer types with an impressive specificity. This is a technically very strong approach with many nifty and thoughtful additions to give this test a very promising first foray – did anybody watch CNN?

While not ready for prime time, which is a tall order for a first report, the authors dutifully point out the need for a prospective real life cohort validation. In the meantime, regardless of the outcome of this particular test, it is a repeated reminder that we need to stay abreast of the advances and the details of each molecular test, especially with a likely very diverse and distinct group of tests to choose from.

Many of us will be part of interpreting results and determining further management. Just as with hereditary cancer genetic panel testing, our technical ability may have stretched beyond our ability to fully understand the implications. Many questions will arise: What about true false positives? False negatives? Intervals? Can such tests replace other screening? How to choose any given test over the other? Should tests be combined or alternated? The tests will be technically refined and are here to stay – we need to get to work on finding answers to the clinically relevant questions.

Home respiratory polygraphy had similar efficacy with substantially lower per-patient cost, compared with traditional polysomnography for diagnosing obstructive sleep apnea, a study showed.
Obstructive sleep apnea (OSA) is a common chronic disease associated with higher risk of cardiovascular disease and traffic accidents and a lower quality of life. Although expensive and time intensive, the polysomnography (PSG) has been the preferred test for diagnosing OSA. Home respiratory polygraphy (HRP) uses portable devices that are less complex than polysomnography and has been shown to have similar effectiveness in diagnosing OSA, compared with PSG, in patients with a high clinical suspicion of OSA. However, there is limited evidence for the cost effectiveness of HRP, compared with PSG (Am J Respir Crit Care Med. 2017 Nov 1;196[9]:1181-90).

Jaime Corral-Peñafiel, MD, of San Pedro de Alcántara Hospital, Cáceres, Spain, and his colleagues sought to compare the long-term effectiveness of HRP to PSG in patients with an intermediate or high suspicion for sleep apnea.

The investigators conducted a multicenter, randomized controlled, noninferiority trial and cost-effectiveness analysis comparing PSG with HRP. Inclusion criteria included snoring or observed sleep apnea, Epworth Sleepiness Scale (ESS)of 10 or higher, and no suspicion of alternative causes for daytime sleepiness. Patients with a suspicion for OSA were randomized to polysomnography or respiratory polygraphy protocols. Both arms received counseling on proper sleep hygiene; counseling on weight loss, if overweight; and auto-CPAP titration if continuous positive airway pressure (CPAP) was clinically indicated.

Assessment of CPAP compliance or dietary and sleep hygiene compliance was assessed at months 1 and 3. ESS, quality of life measures, well-being measures, 24-hour blood pressure monitoring, auto accidents, and cardiovascular events were assessed at baseline and at month 6.

CPAP treatment was indicated in 68% of the PSG arm, compared with 53% of the HRP arm. After intention-to-treat analysis, there was no statistically significant difference between the two groups for ESS improvement (HRP mean, –4.2, vs. PSG mean, –4.9; P = .14). The groups demonstrated similar results for quality of life, blood pressure, polysomnographic assessment at 6 months, CPAP compliance, and rates of cardiovascular events and accidents at follow-up.

The cost-effective analysis demonstrated respiratory polygraphy was less expensive, saving more than 400 euros/patient. “Because the effectiveness (ESS and QALYs [quality-adjusted life-years]) was similar between arms, the HRP protocol is preferable due to its lower cost,” the authors wrote.

In all, 430 patients were randomized to HRP or PSG and consisted mostly of men (70.5%) with a mean body mass index of 30.7 kg/m2. The groups had similar rates of alcohol consumption and hypertension.

Limitations of the study included unblinded randomization to the participants and researchers and the possibility of variability in therapeutic decisions. However, the authors noted that intraobserver variability was minimized by using the Spanish Sleep Network guidelines and centralized assessment.

“[The] HRP management protocol is not inferior to PSG and presents substantially lower costs. Therefore, PSG is not necessary for most patients with suspicion of OSA. This finding could change established clinical practice, with a clear economic benefit,” the authors concluded.

Home respiratory polygraphy continues to impress

This study adds strong evidence to support the use of home respiratory polygraphy for the diagnosis of obstructive sleep apnea in patients without major comorbidities such as severe chronic restrictive or obstructive lung disease, heart failure or unstable cardiovascular disease, major psychiatric diagnoses, and neuromuscular conditions, noted Ching Li Chai-Coetzer, MBBS, PhD, and R.

Doug McEvoy, MBBS, MD, in an accompanying editorial (Am J Respir Crit Care Med. 2017 Nov 1;196[9]:1096-8). However, lower-cost methods to diagnose OSA would still not address unmet needs such as the cost of continuous positive airway pressure and scarcity of sleep physicians to assess patients with OSA, and still may be too expensive for underresourced populations, they said.

Dr. Chai-Coetzer and Dr. McEvoy are affiliated with the Adelaide Institute for Sleep Health at Flinders University and the Sleep Health Service, Southern Adelaide Local Health Network, both in South Australia.

The study was supported by Sociedad Española de Neumología, Air Liquide (Spain), Asociacion de Neumologos del Sur, and Sociedad Extremeña de Neumología. The investigators report no disclosures.

Home sleep apnea testing technology has expanded tremendously in the last decade given the need for expedient diagnosis of obstructive sleep apnea. Despite the American Academy of Sleep Medicine's guidelines for using unattended portable monitoring in the diagnosis of obstructive sleep apnea (OSA) in adults with intermediate to high clinical probability of OSA (Collop et al. J Clin Sleep Med 2007) and widespread usage of a multitude of home sleep testing technologies, questions about its effectiveness in comparison to polysomnography (PSG) and overall cost-benefit benefit remain. This study establishes that home respiratory polygraphy (HRP) was non-inferior to PSG for diagnosis and subsequent OSA treatment using 6-month quality of life and sleepiness measures, but HRP achieved this at substantially lower costs. This was despite higher continuous positive airway pressure prescription rates in the PSG arm as compared to the HRP arm (68% vs. 53%) that was attributed to Apnea-Hypopnea Index underestimations from HRP. While a slightly higher improvement in deep sleep in the PSG arm was seen at 6 months, a number of other key measures such as 24-hour ambulatory blood pressures did not show a difference. Besides demonstration of comparable CPAP usages in the PSG and HRP arms (5.3 hr/d vs. 5.1 hr/d), this study highlights the increasing reliance on quality of life and blood pressure measures as relevant endpoints in cost analyses assessing OSA diagnosis and care-process outcomes.

Varenicline, bupropion not tied to significant increase in neuropsychiatric events in smokers

Neuropsychiatric adverse events do not increase significantly in smokers treated with either varenicline or bupropion, a large cohort study shows.

Both bupropion and varenicline have been tied to long-term smoking cessation in observational studies and randomized trials. However, concerns about adverse neuropsychiatric events, including aggression and suicidality, have been raised. Furthermore, data are limited on the safety of the medications in smokers with known psychiatric conditions.

At the request of the Food and Drug Administration, Dr. Robert M. Anthenelli and his colleagues conducted a randomized, double-blind, triple-dummy, placebo- and active-controlled trial to assess bupropion and varenicline in motivated smokers with and without psychiatric diagnoses for 12 weeks. The efficacy endpoint in the multinational trial, called the Evaluating Adverse Events in a Global Smoking Cessation Study (EAGLES), was abstinence for 9-12 weeks. The primary endpoint was adverse neuropsychiatric events, reported Dr. Anthenelli of the psychiatry department at the University of California, San Diego.

In total, 8,144 participants were randomized to either a nonpsychiatric (n = 4,028) or a psychiatric (n = 4,116) cohort. Men made up 44% of the study population, and the average age was 46.5 years. Most participants were white (82%) and American (52%). The psychiatric cohort included participants with diagnoses of primary mood disorders, anxiety and psychotic disorders, and borderline personality disorders, and 49% reported treatment with a psychotropic medication (Lancet. 2016 Apr 22. doi: 10.1016/S0140-6736).

Overall, the incidence of neuropsychiatric adverse events was similar in the bupropion (4.5%), varenicline (4.0%), nicotine patch (3.9%), and the placebo (3.7%) groups. However, more neuropsychiatric events were reported in the psychiatric cohort than the nonpsychiatric cohort (5.8% versus 2.1%, P less than .0001). Likewise, the psychiatric cohort reported moderate and severe neuropsychiatric adverse events more often in the bupropion group (6.7% versus 2.2%), varenicline (6.5% versus 1.3%), nicotine patch (5.2% versus 2.5%), and placebo groups (4.9% versus 2.4%) than the nonpsychiatric cohort.

In the nonpsychiatric cohort, the risk differences for moderate and severe neuropsychiatric adverse events were –1.28 (95% confidence interval, –2.40 to –0.15) for varenicline vs. placebo and –0.08 (95% CI, –1.37 to 1.21) for bupropion vs. placebo. In the psychiatric cohort, the risk differences for moderate and severe neuropsychiatric adverse events were 1.59 (95% CI, -0.42 to 3.59) for varenicline-placebo and 1.78 (95% CI, -0.24 to 3.81) for bupropion-placebo.

Rates of abstinence were higher in the participants who received varenicline, compared with placebo (OR, 3.61; 95% CI, 3.07-4.24), bupropion (OR, 1.75; 95% CI, 1.52-2.01), and the nicotine patch (OR, 1.68; 95% CI, 1.46-1.93).

The most common adverse events reported included abnormal dreams, headache, insomnia, and nausea.

Dr. Anthenelli and his associates noted several limitations. For example, participants in the psychiatric cohort were stable or in remission; they were restricted to particular psychiatric diagnoses; and participants with current substance abuse or risk for suicide were excluded.

However, they said the EAGLES trial results provide “further evidence that varenicline and bupropion can be used safely by psychiatrically stable smokers,” they wrote. “Although varenicline appears to be the most effective single pharmacotherapy available, all of the first-line medications – varenicline, bupropion, and nicotine patch – are efficacious, compared with placebo.”

The authors report relationships with several pharmaceutical companies, including Pfizer and GlaxoSmithKline. The study was funded by Pfizer and GlaxoSmithKline.

Study of LGBQ Youth Highlights Behavioral Health Differences in Each Group

Mental health symptoms and severity differed across a cohort of lesbian, gay, bisexual, and questioning (LGBQ) adolescents, highlighting the need to consider behavioral health separately for each group.

Lesbian, gay, or bisexual youth demonstrate higher rates of depression, anxiety, self-harm, and suicidal ideation than do youth who identify as heterosexual, several studies have reported. Youth who identify as “unsure” or “questioning” are at an even higher risk of suicidality, depression, and victimization than their LGB counterparts.

With a lack of research focusing on the subgroup of youth identifying as questioning or bisexual, Annie Shearer and her colleagues at Drexel University in Philadelphia sought to assess the behavioral health of heterosexual and LGBQ youth in a large primary care sample (J Adolesc Health. 2016. doi: 10.1016/j.jadohealth.2016.02.005).

The cohort included 2,513 youth aged 14-24 years, with 61% female. Same sex attraction was reported in 2%, attraction to both sexes was reported in 4%, attraction to the opposite sex was reported by 92%, and unsure sexuality preferences were reported in 2%.

The study was conducted using a Web-based screening tool, the Behavioral Health Screen owned by the Children’s Hospital of Philadelphia, in 10 primary care offices in semiurban and rural communities. Deidentified data were collected on demographics, social factors, medical history, and psychiatric factors including depression, anxiety, substance use, suicidality, and trauma.

An analysis of the data demonstrated females identifying as questioning or bisexual had higher scores for traumatic distress, anxiety, and depression than did their heterosexual peers; there were no differences among lesbian, bisexual, or questioning females in these areas. Female youth in those three sexual minority groups had significantly higher lifetime suicide scores. Bisexual females reported higher scores for current suicide as well as substance abuse.

Male participants identifying as bisexual or gay reported significantly higher scores for traumatic distress and depression, with gay participants reporting higher anxiety scores. Bisexual male youth had significantly higher lifetime suicide scores. There did not appear to be a higher risk for questioning males. There were no differences between the groups in terms of current suicide or substance use scores.

Study limitations included the complex nature of sexuality and the self-reported nature of the data, the investigators noted.

“Our findings underscore the willingness of sexual minority youth to disclose the same-sex attractions in PC [primary care] settings,” the authors concluded. “Medical providers should in turn be receptive to this information and engage youth in conversations about these issues, particularly in contexts where the same-sex or bisexual attractions are stigmatized.”

“Although sexual orientation does not cause mental illness,” clinicians should be aware of the association between LGBQ status and mental health, Ms. Shearer and her colleagues said.

The study was funded by a grant from the Substance Abuse and Mental Health Services Administration. Coauthor Guy Diamond, Ph.D., reported potential royalty payments if the Behavioral Health Screen is made public.

‘Shark tank’ panel probes GI innovations at AGA Tech Summit

BOSTON – Several innovators had the opportunity to present their novel technologies to a five-person “shark tank” panel – two entrepreneurs, a practicing physician, a venture capitalist, and a businessman – at the 2016 AGA Tech Summit.

After the innovators explained why they expected their products to fill an unmet need, the “sharks” probed for weaknesses and offered advice on what data were needed to confirm a viable advantage over existing options.

“These presentations offer a glimpse into what innovators are working on to improve the practice of gastroenterology,” said Michael L. Kochman, M.D., AGAF, one of the “sharks,” who is chair of the AGA Center for GI Innovation and Technology, which sponsored the summit.

“This ‘shark tank’ is a perfect illustration of what the AGA Center for GI Innovation and Technology is all about – we’re here to help move the field forward and discuss what’s next for the care of patients with digestive disorders.”

In addition to Dr. Kochman, the panel comprised Jay Pasricha, M.D., professor of medicine at Johns Hopkins University, who has been involved in several start-ups; Thomas Shehab, MD, a trained gastroenterologist who is now a principal at Arboretum Ventures; Mr. Brian Tinkham, a founder of Beacon Endoscopic and now vice president, New Technologies, GI Solutions, at Medtronic; and Mr. David Pierce, senior vice president at Boston Scientific.

Amenity Health – MedCline™

Amenity Health developed MedCline™ based on the work of Dr. Carl Melcher, as a positional therapy for nocturnal acid reflux in patients with GERD refractory to pharmacologic treatment. As a component of the GERD treatment plan, MedCline™ is a sleeping device designed to raise the torso and facilitate left-side positioning, both of which have been shown to reduce the risk of nocturnal gastroesophageal reflux disease (GERD). Currently, there are five published studies assessing MedCline™ for nocturnal reflux.

“With so many patients still having nighttime reflux even on daily PPIs and growing concerns of long-term side effects of these medications, it’s a perfect time to bring an effective, nonpharmacological treatment to market like MedCline,™” noted Aaron Clark, COO and co-inventor, at Amenity Health.

“We are happy to be offering both patients and physicians a much-needed treatment alternative for nocturnal GERD and are grateful to our research partners for their studies showing that MedCline™ is far more effective at treating nocturnal GERD than bed wedges or propping up the head of the bed,” Mr. Clark said. “We now hope to garner the support of the professional societies and payers to help make MedCline™ more accessible to patients who are in desperate need of nighttime relief.”

All of the sharks agreed that the team at Amenity Health should focus on marketing this device to patients, rather than physicians. Expressing some skepticism about the prospects for third-party reimbursement, all agreed that a direct-to-consumer marketing strategy is needed even if the company can generate more data showing value, such as decreased use of pharmacologic therapy. When told by Mr. Clark that the plan was to market to both physicians and patients, Dr. Pasricha cautioned, “I would require a higher level of evidence [than what was so far presented] before I would recommend it to patients.”

BioInnovate Ireland – Microwave ablation of varices

According to Jonathan Bouchier-Hayes, BSc, MBA, at BioInnovate, current strategies for the treatment of gastroesophageal varices have several limitations. Endoscopic banding, in particular, which is commonly used, requires two to four treatments over several weeks and is associated with a high risk of recurrence. BioInnovate proposes a microwave energy solution integrated into a standard endoscope. By inducing coagulation, the aim of microwave energy is to treat gastroesophageal varices in a single procedure. The advantage of microwave therapy is that it appears to preserve the mucosal layer, reducing the risk of complications associated with endoscopic banding and providing a reduced risk of recurrence. In the experimental studies conducted so far, the fibrosis produced by microwave energy also proved to be a barrier for recurrence. Mr. Bouchier-Hayes believes that the reduction in rebleeding and recurrence will make this approach cost effective. Clinical trials have not yet been initiated.

Several sharks implied that the disadvantages of endoscopic banding, which is widely performed and associated with a relatively low rate of complications, might be less of a concern than was in Mr. Bouchier-Hayes’ analysis of the unmet need, but they were intrigued with this concept if clinical development includes studies that show a cost advantage over current options. To invest, Dr. Shehab reported that he would require a detailed understanding of the specific clinical trials that were planned from which a “go or no-go” decision would be made for further development. Others agreed that it is not just efficacy but economic viability that will be important as development proceeds.

 

 

GI-Logic – AbStats™ system

In collaboration with the UCLA gastroenterology department and the UCLA Wireless Health Institute, GI-Logic developed the AbStats™ system to provide continuous telemetry monitoring of the gastrointestinal tract function. With sensors placed on the patient’s abdomen, telemetry is employed to record and analyze vibrations of the digestive tract. Although there is a wide number of applications being considered, one focus has been on the ability of the AbStats™ system to evaluate postoperative ileus. Clinical studies suggest that this tool can signal when patients can resume eating, including distinguishing between suitability for solid foods relative to a liquid diet.

“The AbStats™ system is being studied in a number of chronic GI conditions and will allow clinic physicians a tool to monitor patient conditions and therapeutic impact of both drugs and interventional therapies. The AbStats™ system was recently cleared by the Food and Drug Administration and will be launching in selective centers in May of 2016,” noted Ken Beres, vice president of marketing and business development at GI Logic.

“The system will allow for care teams to for the first time use objective data to guide the feeding and pharmacological management of patients to both improve outcomes and reduce health care expenses.”

The sharks agreed that this tool has potential clinical utility, but there was also general consensus that more data are needed to confirm that it has value from an economic perspective. They suggested that studies are needed to show how the tool alters clinical decisions in a way that saves money or improves outcomes. Dr. Pasricha suggested, “You have to prove that you are not just another layer of diagnosis,” but are providing information that leads to improved patient care.

GI Therapies – TAGS™

David Fisher
David Fischer

The transabdominal gastrointestinal stimulation (TAGS™) device was developed by GI Therapies as a noninvasive tool for the treatment of chronic constipation. The TAGS™ device, which sends small electric pulses to promote peristaltic contractions, was tested in a small pilot study of six women with gastroparesis and chronic constipation. All five patients who required nutritional support (total parenteral nutrition or enteral feedings) at the start of the study were no longer requiring nutritional support after 3-4 months.

GI Therapies is looking to conduct a larger, sham-controlled trial to investigate the use of TAGS™ for the treatment of symptoms of gastroparesis, according to Dr. David Fischer, a principal at GI Therapies, who noted that current therapeutic options for the treatment of gastroparesis, which is a relatively common problem, are “very limited.” He indicated that interest in alternatives to the current array of pharmacologic therapies “is substantial.”

The sharks agreed that gastroparesis is a common and challenging clinical complaint, and they also encouraged the plans to conduct a well-controlled trial using a sham device. However, there was also consensus that patient selection will be critical to efforts to demonstrate a positive outcome, as placebo responses are substantial and not all forms of gastroparesis may respond to this form of electrical stimulation. Several sharks, including Mr. Tinkham, suggested that the developers should already be considering what type of company might be most interested in acquiring this device if clinical studies confirm benefit.

Wake Forest Institute for Regenerative Medicine – BioSphincter™

Using autologous enteric neural progenitor and smooth muscle cells, Khalil N Bitar, Ph.D., AGAF, was able to bioengineer innervated internal anal sphincters, which have been successfully implanted into rabbits after a sphincterectomy. In these experimental studies, sustained continence was restored over a follow-up of 12 months.

“Fecal incontinence, the inability to control bowel movements allowing stool to leak unexpectedly from the rectum, afflicts 6.6 million people in the United States. The true prevalence is thought to be much higher, but is underreported due to social factors. Fecal incontinence represents the second leading cause of institutionalization in the elderly,” Dr. Bitar noted.

“Using autologous cell sources, bioengineered internal anal sphincter, BioSphincter™ is a unique regenerative medicine solution to reinstate function in the anorectum, restoring both smooth muscle and intrinsic neural components, resulting in continence. This regenerative medicine approach to reinstate physiological function to treat fecal incontinence using BioSphincter is promising for translation into clinical practice,” Dr. Bitar added.

The sharks were enthusiastic. Although Dr. Bitar was faced with a barrage of questions about the logistics of harvesting muscle and neuroendocrine cells to create an effective implantable sphincter, they suggested that this could provide a major advance in a condition for which there are now very few options. However, they noted that enthusiasm must be tempered by the relatively early clinical development and the likelihood of many potential hurdles to overcome. Of those intrigued, Mr. Pierce initially questioned whether this approach could be adequately protected as intellectual property from competitors but was reassured by Dr. Bitar’s description of the patentable aspects of the bioengineering.

 

 

Dark Canyon Labs – DCL-101 colonoscopy preparation

In an effort to make the colonoscopy preparation process more tolerable, Dark Canyon Labs has developed a novel preparation designed to avoid the bad taste of current options while preserving efficacy. Currently, bowel preps combine polyethylene glycol (PEG) solutions with salts to achieve the cathartic effect. The PEG is tasteless but the salts are not. The concept of the novel prep is to administer the PEG in the usual liquid form but deliver the salts by capsule, avoiding the bad taste. Once the PEG and capsules reach the stomach, they mix and reform the same concentration of a standard prep.

The product as currently formulated reproduces the electrolyte composition of GoLYTELY®. Rather than 4 liters of the typical preps, the patient takes 2 liters of solution along with 48 capsules, according to Dr. Dale Bachwich, cofounder and chief medical officer of Dark Canyon Laboratories and a practicing gastroenterologist.

“A better colonoscopy prep benefits everyone – patients, physicians, endoscopy centers, payers, and society,” said Dr. Bachwich, who presented several sets of data demonstrating that patients far preferred the tasteless prep despite the 48-capsule requirement. Like standard bowel preps, the new formulation can be taken in single or split doses.

The sharks, who were given a taste test in which they compared the liquid portion of the new bowel prep to a conventional prep, agreed that the new prep was relatively tasteless and could provide a large advantage over current formulations despite the large pill burden. However, there was unanimous agreement that the purported advantages, including greater compliance and fewer canceled colonoscopies due to inadequate prep, need to be demonstrated in a well-controlled trial, particularly if the novel bowel preparation has a higher price. Mr. Pierce said that there is a potential value proposition for the advantages Dr. Bachwich outlined, but objective supportive evidence is needed.

When told by Mr. Clark that the plan was to market to both physicians and patients, Dr. Pasricha cautioned, “I would require a higher level of evidence [than what was so far presented] before I would recommend it to patients.”

BioInnovate Ireland – Microwave ablation of varices

According to Jonathan Bouchier-Hayes, BSc, MBA, at BioInnovate, current strategies for the treatment of gastroesophageal varices have several limitations. Endoscopic banding, in particular, which is commonly used, requires two to four treatments over several weeks and is associated with a high risk of recurrence. BioInnovate proposes a microwave energy solution integrated into a standard endoscope. By inducing coagulation, the aim of microwave energy is to treat gastroesophageal varices in a single procedure. The advantage of microwave therapy is that it appears to preserve the mucosal layer, reducing the risk of complications associated with endoscopic banding and providing a reduced risk of recurrence. In the experimental studies conducted so far, the fibrosis produced by microwave energy also proved to be a barrier for recurrence. Mr. Bouchier-Hayes believes that the reduction in rebleeding and recurrence will make this approach cost effective. Clinical trials have not yet been initiated.

Several sharks implied that the disadvantages of endoscopic banding, which is widely performed and associated with a relatively low rate of complications, might be less of a concern than was in Mr. Bouchier-Hayes’ analysis of the unmet need, but they were intrigued with this concept if clinical development includes studies that show a cost advantage over current options. To invest, Dr. Shehab reported that he would require a detailed understanding of the specific clinical trials that were planned from which a “go or no-go” decision would be made for further development. Others agreed that it is not just efficacy but economic viability that will be important as development proceeds.

 

 

GI-Logic – AbStats™ system

In collaboration with the UCLA gastroenterology department and the UCLA Wireless Health Institute, GI-Logic developed the AbStats™ system to provide continuous telemetry monitoring of the gastrointestinal tract function. With sensors placed on the patient’s abdomen, telemetry is employed to record and analyze vibrations of the digestive tract. Although there is a wide number of applications being considered, one focus has been on the ability of the AbStats™ system to evaluate postoperative ileus. Clinical studies suggest that this tool can signal when patients can resume eating, including distinguishing between suitability for solid foods relative to a liquid diet.

“The AbStats™ system is being studied in a number of chronic GI conditions and will allow clinic physicians a tool to monitor patient conditions and therapeutic impact of both drugs and interventional therapies. The AbStats™ system was recently cleared by the Food and Drug Administration and will be launching in selective centers in May of 2016,” noted Ken Beres, vice president of marketing and business development at GI Logic.

“The system will allow for care teams to for the first time use objective data to guide the feeding and pharmacological management of patients to both improve outcomes and reduce health care expenses.”

The sharks agreed that this tool has potential clinical utility, but there was also general consensus that more data are needed to confirm that it has value from an economic perspective. They suggested that studies are needed to show how the tool alters clinical decisions in a way that saves money or improves outcomes. Dr. Pasricha suggested, “You have to prove that you are not just another layer of diagnosis,” but are providing information that leads to improved patient care.

GI Therapies – TAGS™

The transabdominal gastrointestinal stimulation (TAGS™) device was developed by GI Therapies as a noninvasive tool for the treatment of chronic constipation. The TAGS™ device, which sends small electric pulses to promote peristaltic contractions, was tested in a small pilot study of six women with gastroparesis and chronic constipation. All five patients who required nutritional support (total parenteral nutrition or enteral feedings) at the start of the study were no longer requiring nutritional support after 3-4 months.

GI Therapies is looking to conduct a larger, sham-controlled trial to investigate the use of TAGS™ for the treatment of symptoms of gastroparesis, according to Dr. David Fischer, a principal at GI Therapies, who noted that current therapeutic options for the treatment of gastroparesis, which is a relatively common problem, are “very limited.” He indicated that interest in alternatives to the current array of pharmacologic therapies “is substantial.”

The sharks agreed that gastroparesis is a common and challenging clinical complaint, and they also encouraged the plans to conduct a well-controlled trial using a sham device. However, there was also consensus that patient selection will be critical to efforts to demonstrate a positive outcome, as placebo responses are substantial and not all forms of gastroparesis may respond to this form of electrical stimulation. Several sharks, including Mr. Tinkham, suggested that the developers should already be considering what type of company might be most interested in acquiring this device if clinical studies confirm benefit.

Wake Forest Institute for Regenerative Medicine – BioSphincter™

Using autologous enteric neural progenitor and smooth muscle cells, Khalil N Bitar, Ph.D., AGAF, was able to bioengineer innervated internal anal sphincters, which have been successfully implanted into rabbits after a sphincterectomy. In these experimental studies, sustained continence was restored over a follow-up of 12 months.

“Fecal incontinence, the inability to control bowel movements allowing stool to leak unexpectedly from the rectum, afflicts 6.6 million people in the United States. The true prevalence is thought to be much higher, but is underreported due to social factors. Fecal incontinence represents the second leading cause of institutionalization in the elderly,” Dr. Bitar noted.

“Using autologous cell sources, bioengineered internal anal sphincter, BioSphincter™ is a unique regenerative medicine solution to reinstate function in the anorectum, restoring both smooth muscle and intrinsic neural components, resulting in continence. This regenerative medicine approach to reinstate physiological function to treat fecal incontinence using BioSphincter is promising for translation into clinical practice,” Dr. Bitar added.

The sharks were enthusiastic. Although Dr. Bitar was faced with a barrage of questions about the logistics of harvesting muscle and neuroendocrine cells to create an effective implantable sphincter, they suggested that this could provide a major advance in a condition for which there are now very few options. However, they noted that enthusiasm must be tempered by the relatively early clinical development and the likelihood of many potential hurdles to overcome. Of those intrigued, Mr. Pierce initially questioned whether this approach could be adequately protected as intellectual property from competitors but was reassured by Dr. Bitar’s description of the patentable aspects of the bioengineering.

 

 

Dark Canyon Labs – DCL-101 colonoscopy preparation

In an effort to make the colonoscopy preparation process more tolerable, Dark Canyon Labs has developed a novel preparation designed to avoid the bad taste of current options while preserving efficacy. Currently, bowel preps combine polyethylene glycol (PEG) solutions with salts to achieve the cathartic effect. The PEG is tasteless but the salts are not. The concept of the novel prep is to administer the PEG in the usual liquid form but deliver the salts by capsule, avoiding the bad taste. Once the PEG and capsules reach the stomach, they mix and reform the same concentration of a standard prep.

The product as currently formulated reproduces the electrolyte composition of GoLYTELY®. Rather than 4 liters of the typical preps, the patient takes 2 liters of solution along with 48 capsules, according to Dr. Dale Bachwich, cofounder and chief medical officer of Dark Canyon Laboratories and a practicing gastroenterologist.

“A better colonoscopy prep benefits everyone – patients, physicians, endoscopy centers, payers, and society,” said Dr. Bachwich, who presented several sets of data demonstrating that patients far preferred the tasteless prep despite the 48-capsule requirement. Like standard bowel preps, the new formulation can be taken in single or split doses.

The sharks, who were given a taste test in which they compared the liquid portion of the new bowel prep to a conventional prep, agreed that the new prep was relatively tasteless and could provide a large advantage over current formulations despite the large pill burden. However, there was unanimous agreement that the purported advantages, including greater compliance and fewer canceled colonoscopies due to inadequate prep, need to be demonstrated in a well-controlled trial, particularly if the novel bowel preparation has a higher price. Mr. Pierce said that there is a potential value proposition for the advantages Dr. Bachwich outlined, but objective supportive evidence is needed.

BOSTON – Several innovators had the opportunity to present their novel technologies to a five-person “shark tank” panel – two entrepreneurs, a practicing physician, a venture capitalist, and a businessman – at the 2016 AGA Tech Summit.

After the innovators explained why they expected their products to fill an unmet need, the “sharks” probed for weaknesses and offered advice on what data were needed to confirm a viable advantage over existing options.

“These presentations offer a glimpse into what innovators are working on to improve the practice of gastroenterology,” said Michael L. Kochman, M.D., AGAF, one of the “sharks,” who is chair of the AGA Center for GI Innovation and Technology, which sponsored the summit.

“This ‘shark tank’ is a perfect illustration of what the AGA Center for GI Innovation and Technology is all about – we’re here to help move the field forward and discuss what’s next for the care of patients with digestive disorders.”

In addition to Dr. Kochman, the panel comprised Jay Pasricha, M.D., professor of medicine at Johns Hopkins University, who has been involved in several start-ups; Thomas Shehab, MD, a trained gastroenterologist who is now a principal at Arboretum Ventures; Mr. Brian Tinkham, a founder of Beacon Endoscopic and now vice president, New Technologies, GI Solutions, at Medtronic; and Mr. David Pierce, senior vice president at Boston Scientific.

Amenity Health – MedCline™

Amenity Health developed MedCline™ based on the work of Dr. Carl Melcher, as a positional therapy for nocturnal acid reflux in patients with GERD refractory to pharmacologic treatment. As a component of the GERD treatment plan, MedCline™ is a sleeping device designed to raise the torso and facilitate left-side positioning, both of which have been shown to reduce the risk of nocturnal gastroesophageal reflux disease (GERD). Currently, there are five published studies assessing MedCline™ for nocturnal reflux.

“With so many patients still having nighttime reflux even on daily PPIs and growing concerns of long-term side effects of these medications, it’s a perfect time to bring an effective, nonpharmacological treatment to market like MedCline,™” noted Aaron Clark, COO and co-inventor, at Amenity Health.

“We are happy to be offering both patients and physicians a much-needed treatment alternative for nocturnal GERD and are grateful to our research partners for their studies showing that MedCline™ is far more effective at treating nocturnal GERD than bed wedges or propping up the head of the bed,” Mr. Clark said. “We now hope to garner the support of the professional societies and payers to help make MedCline™ more accessible to patients who are in desperate need of nighttime relief.”

All of the sharks agreed that the team at Amenity Health should focus on marketing this device to patients, rather than physicians.

Gait speed hones risk stratification of elderly heart failure patients

Gait speed was independently associated with hospitalization and death and aided in risk stratification of elderly patients with heart failure in a study reported online March 9 in JACC Heart Failure.

Optimal clinical management of heart failure is dependent on accurate prognostic stratification, Dr. Giovanni Pulignano and his coinvestigators wrote. Geriatric conditions such as frailty, cognitive impairment, and disability impact prognosis along with comorbidities and cardiac disease. Further, gait speed is a marker of frailty and is predictive of adverse health events in older patients, including mortality. However, there is limited research on the impact of geriatric conditions in heart failure studies.

Dr. Pulignano of San Camillo Hospital in Rome and colleagues sought to examine the relationship between gait speed in older patients with heart failure and the risk of hospitalization and death.

The investigators calculated the predicted all-cause mortality using the Cardiac and Comorbid Conditions Heart Failure (3C-HF) score. Variables included in the 3C-HF score are left ventricular ejection fraction of less than 20%, New York Heart Association class III-IV heart failure, no renin-angiotensin inhibitor treatment, no beta-blocker treatment, severe valvular heart disease, diabetes with macro- or microangiopathy, atrial fibrillation, hypertension, anemia, renal dysfunction, and older age.

Participants were at least 70 years old, with clinically stable heart failure with normal or reduced left ventricular ejection fraction and a previous hospitalization necessitating intravenous inotropes, diuretics, and/or vasodilators for heart failure.

Exclusion criteria included a condition that would decrease their walking speed, valvular heart disease with surgery planned, long-term intravenous inotrope treatment, or living in a nursing home.

Gait speed was assessed over 4 meters and grouped into groups of slow walkers (up to 0.65 m/s), intermediate walkers (0.66-0.99 m/s), and fast walkers (at least 1.0 m/s). Participants were allowed to use a walker or cane as a walking aid.

Data were analyzed on 331 patients (mean age 78 years, 43% women) with clinically stable and optimized chronic heart failure (mean NYHA class 2.7, mean left ventricular ejection fraction 35%). The mean 3C-HF score was 19.7 points.

The mean gait speed was 0.74 m/s, with 35% (115 patients) demonstrating severely reduced (less than or equal to 0.65 m/s) gait speed.

After 1 year of follow-up, they found a significant association between the measured gait speed and 1-year mortality, with 9.1%, 21.9%, and 38.3% for the high, intermediate, and low tertiles, respectively (P less than .001). A similar relationship was found for gait speed and heart failure–related hospitalization (26.6%, 58.6%, and 71.3%, respectively; P = .002) and all-cause hospitalization (26.6%, 58.6%, and 71.3%, respectively; P = .002).

Multivariate analysis revealed an independent association between gait speed and lower risk of all-cause death (hazard ratio, 0.62; P = .008). Gait speed was also associated with a lower risk for all-cause hospitalizations (HR, 0.74; P = .002) and heart failure–related hospitalizations (HR, 0.69; P = .004).

Finally, when gait speed was included in the 3C-HF risk score, accuracy of risk stratification for all-cause death (net reclassification improvement, 0.49; P less than .001) and heart failure admissions (NRI, 0.37; P less than .001) was improved (JCHF. 2016 Mar 9. doi:10.1016/j.jchf.2015.12.017).

“Gait speed, in combination with a validated clinical risk score, improves prognosis prediction in older HF patients,” the investigators concluded. “Frailty assessment using gait speed is simple and inexpensive and suggests new strategies for intervention. Its measurement should be incorporated in the routine clinical evaluation of older patients with HF.”

The study was supported by the ADRIANO-Italian Association for Research on Cardiac Disease in Older Patients. The authors had no disclosures.

Among hospitalized patients with diabetes, 25% have undiagnosed diabetic retinopathy

The prevalence of undiagnosed diabetic retinopathy was 25% and that of sight-threatening diabetic retinopathy was 19% of an inpatient population of patients with diabetes, compared with the general population; researchers identified several barriers to ophthalmic care.

Diabetic retinopathy and sight-threatening diabetic retinopathy are estimated at a prevalence of 28.5% and 4.4%, respectively. In contrast, there is little research in to the prevalence of undiagnosed diabetic retinopathy or sight-threatening diabetic retinopathy in higher risk inpatients.

Dr. Jessica Kovarik, who at the time of this research was with the UPMC Eye Center at the University of Pittsburgh, and her associates sought to identify the prevalence of undiagnosed diabetic retinopathy among inpatients with established diabetes as well as barriers to diabetic retinopathy examinations and treatment.

They conducted a cross-sectional analysis of diabetic patients admitted to an urban teaching hospital in Pittsburgh. Digital funduscopic images were obtained to determine the presence and severity of diabetic retinopathy and macular edema. Questionnaires assessed barriers to ophthalmic examinations and demographics (BMJ Open Diab Res Care. 2016;4:e000164 [doi: 10.1136/bmjdrc-2015-000164]).

In total, 113 patients were eligible and 5 were excluded from analysis of diabetic retinopathy prevalence due to an inability to take images or poor-quality images.

Among the patients, 61 were women, 83 were white, and 34 were aged 50-60 years. Most had health insurance (89%) and an ophthalmologist (64%), and most understood that diabetic retinopathy affects vision (91%). Further, patients reported a history of type 2 diabetes (96%), hypertension (85%), hyperlipidemia (68%), renal disease (25%), peripheral vascular disease (55%), and coronary artery disease (52%).

Among those who had not had a dilated funduscopic examination within a year, barriers to screening examination included transportation issues, physical disability, too many appointments or being too sick, cost, lack of time or priority, or no visual impairment. Forty percent reported having an eye examination within the year and 5% reported never having an eye examination.

The investigators identified 7 patients with clinically significant macular edema (6%), 13 with proliferative diabetic retinopathy (12%), and 1 with severe (1%), 14 with moderate (13%), and 16 with mild nonproliferative diabetic retinopathy (15%). Overall, 44% of the patients had diabetic retinopathy, with 25% previously undiagnosed. Further, sight-threatening diabetic retinopathy was found in 19%, with 3.7% previously undiagnosed.

Finally, after multivariable analysis, a longer duration of diabetes (odds ratio, 1.08 per year; 95% confidence interval, 1.014-1.147; P =.017) and renal disease (OR, 3.86; 95% CI, 1.22-12.27; P =.022) was associated with diabetic retinopathy. Further, of the 17 patients admitted with osteomyelitis or a nonhealing diabetic ulcer, 15 (88.2%) had diabetic retinopathy.

“Curiously, most inpatients in our population (91%) are aware of the ocular complications of diabetes, and many (64%) do have ophthalmologists (more than any other subspecialty listed), yet only a minority (40%) of patients are getting the recommended standard of care screening examinations. Barriers that are unique to this high-risk population may explain this disparity,” the authors wrote.

The study was funded by the National Institutes of Health, Eye and Ear Foundation of Pittsburgh, Clinical and Translational Science Institute, the University of Pittsburgh, and a grant from Research to Prevent Blindness. One of the researchers, Dr. Jann Johnston, reported speaking for Medtronic, Lilly, and Sanofi.

Key clinical point: Among hospitalized patients with diabetes, 25% had undiagnosed diabetic retinopathy and 19% had undiagnosed sight-threatening diabetic retinopathy; it was most common in patients with a nonhealing ulcer and/or a history of renal disease at admission.

Major finding: While many patients knew they were at risk for retinopathy, they faced significant barriers to receiving ophthalmic care, including lack of transportation and physical disability.

Data source: A cross-sectional analysis of 113 consecutive patients with diabetes who were admitted to an urban teaching hospital with digital funduscopic images to determine the presence and severity of diabetic retinopathy and questionnaires to assess barriers to care.

Disclosures: The study was funded by the National Institutes of Health, Eye and Ear Foundation of Pittsburgh, Clinical and Translational Science Institute, the University of Pittsburgh, and a grant from Research to Prevent Blindness.

Contraceptive ring, implant, and DMPA tied to lower sexual interest

Compared with women using copper IUDs, women using depot medroxyprogesterone acetate, the contraceptive ring, and the implant were more likely to report a lack of interest in sex in a survey.

Women reporting side effects are twice as likely to discontinue their oral contraceptive pills and subsequently are at risk for unintended pregnancy. Further, sexual side effects have been reported by one in five women taking oral contraceptives, despite research indicating little impact on sex drive in most women taking the drugs. In this study, Dr. Jeffrey Peipert of Washington University, St. Louis, and his colleagues sought to clarify whether there is any association between other forms of hormonal contraception and effects on sexual desire.

The researchers performed a cross-sectional analysis of data from the Contraceptive CHOICE Project 6-month survey. The Contraceptive CHOICE Project was a prospective cohort study of 9,256 women that aimed to promote reversible, long-acting contraceptive methods and lessen barriers to all forms of contraception.

Complete data were available on 1,938 participants who had a mean age of 25 years. Half of the participants were black, 51% were nulliparous, and 59% had never married or were single. The contraception methods used included the levonorgestrel IUD (43%), the subdermal contraceptive implant (23%), the copper IUD (14%), oral contraceptive pills (7%), depot medroxyprogesterone acetate (DMPA) (6%), the contraceptive vaginal ring (5%), and the contraceptive patch (2%).

Overall, 23.9% of the study participants reported lacking interest in sex for several months or more. Women reporting a lack of sexual interest were more likely to be black (odds ratio, 2.23), and living with a partner or married (OR, 1.51). Women who had more children, reported depression or poor health, and had a low socioeconomic status were also more likely to report a lack of interest in sex (Obstet Gynecol. 2016;127:563-72).

When compared with women using the copper IUD, women using DMPA were more likely to report lack of interest in sex at 6 months (adjusted OR, 2.61; 95% confidence interval, 1.47-4.61). Similar trends were seen for the vaginal ring (aOR, 2.53; 95% CI, 1.37-4.69), and the contraceptive implant (aOR, 1.60; 95% CI, 1.03-2.49). Likewise, more women using DMPA reported not finding sex pleasurable than women using the copper IUD (20% versus 11.9%, P = .04).

The researchers found no association between lack of libido and the hormonal IUD, oral contraceptive pill, and contraceptive patch.

“Lack of interest in sex in implant and DMPA users may be related to the hormonal composition of these methods,” the researchers wrote. “The implant and DMPA injection are the only two contraceptive methods included in this study that release progestins systemically. Although there is conflicting evidence concerning a link between progestins and libido, there is some evidence to suggest that estrogens play an essential role in female sexuality.”

The researchers stressed that confirmation of the findings is warranted.

The Contraceptive CHOICE Project was funded by the Susan T. Buffett Foundation and this study was supported by an award from the National Institutes of Health. Dr. Peipert reported research funding from Bayer, Teva, and Merck, and serving on the advisory boards for Teva and Perrigo.
