TOPLINE:

A greater proportion of patients with active systemic lupus erythematosus (SLE) treated with belimumab plus standard therapy achieved the newest definitions for remission and low disease activity compared with those treated with placebo plus standard therapy, with benefits observed as early as week 28 for remission and week 8 for disease activity, according to pooled results from five clinical trials.

METHODOLOGY:

• Researchers conducted an integrated post hoc analysis of five randomized phase 3 clinical trials to evaluate the attainment of remission and low disease activity in adult patients with active, autoantibody-positive SLE.
• A total of 3086 patients (median age, 36 years; 94% women) were randomly assigned to receive standard therapy with intravenous belimumab 10 mg/kg monthly or subcutaneous belimumab 200 mg weekly (n = 1869) or placebo (n = 1217).
• The proportion of patients who achieved definitions of remission in SLE (DORIS) remission and lupus low disease activity state (LLDAS) by visit up to week 52 was assessed.
• The analysis also evaluated the time taken to achieve sustained (at least two consecutive visits) and maintained (up to week 52) DORIS remission and LLDAS.

TAKEAWAY:

• At week 52, a higher proportion of patients receiving belimumab vs placebo achieved DORIS remission (8% vs 6%; risk ratio [RR], 1.51; P = .0055) and LLDAS (17% vs 10%; RR, 1.74; P < .0001).
• The earliest observed significant benefit of belimumab over placebo in patients with a higher baseline disease activity was at week 20 for DORIS remission (RR, 2.09; P = .043) and at week 16 for LLDAS (RR, 1.46; P = .034), with both maintained through week 52.
• The proportion of patients who attained DORIS remission and LLDAS as early as week 28 and week 8, respectively, was higher in the belimumab group than in the placebo group, with both maintained through week 52.
• Patients on belimumab were more likely to have a sustained and maintained DORIS remission (hazard ratio [HR], 1.53; P = .013) and LLDAS (HR, 1.79; P < .0001) at any timepoint.

IN PRACTICE:

“The data clearly support that belimumab is a valuable addition toward accomplishing and maintaining remission or LLDAS,” George Bertsias, MD, PhD, University of Crete Medical School, Heraklion, Greece, and Jinoos Yazdany, MD, University of California San Francisco, wrote in a related comment.

SOURCE:

This study, led by Ioannis Parodis, MD, Karolinska Institutet and Karolinska University Hospital, Stockholm, Sweden, was published online on August 26, 2024, in The Lancet Rheumatology.

LIMITATIONS: 

Due to the post hoc nature of the analysis, the trials were not specifically designed to have adequate statistical power to demonstrate the difference between patients who did or did not achieve DORIS remission or LLDAS. The analysis was limited to patients who met the eligibility criteria, and the outcomes are not generalizable to populations outside a clinical trial setting. The study population had high disease activity, which made it challenging to attain the treatment targets.

DISCLOSURES:

The five trials included in this analysis were funded by GSK. The study was supported by the Swedish Rheumatism Association, King Gustaf V’s 80-year Foundation, the Swedish Society of Medicine, Nyckelfonden, Professor Nanna Svartz Foundation, Ulla and Roland Gustafsson Foundation, Region Stockholm, and Karolinska Institutet. Some authors reported receiving grants, speaker honoraria, or consulting fees from various pharmaceutical companies. Some authors reported being employees and owning stocks and shares of GSK.

TOPLINE:

An artificial intelligence (AI)-powered clinical documentation tool helped reduce time spent on electronic health records (EHR) at home for almost 48% physicians, and nearly 45% reported less weekly time spent on EHR tasks outside of normal work hours.

METHODOLOGY:

• Researchers recruited 112 clinicians from family medicine, internal medicine, and general pediatrics in North Carolina and Georgia.
• Patients were divided into an intervention group (n = 85) and control group (n = 55), with the intervention group receiving a 1-hour training program on a commercially available AI tool.
• A seven-question survey was administered to participants before and 5 weeks after the intervention to evaluate their experience.

TAKEAWAY:

• The researchers found 47.1% of clinicians in the intervention group reported spending less time on the EHR at home compared with 14.5% in the control group (P < .001); 44.7% reported decreased weekly time on the EHR outside normal work hours compared with 20% in the control group (P = .003).
• The study revealed 43.5% of physicians who used the AI instrument reported spending less time on documentation after visits compared with 18.2% in the control group (P = .002).
• Further, 44.7% reported less frustration when using the EHR compared with 14.5% in the control group (P < .001).

IN PRACTICE:

“Approximately half of clinicians using the AI-powered clinical documentation tool based on interest reported a positive outcome, potentially reducing burnout. However, a significant subset did not find time-saving benefits or improved EHR experience,” the authors of the study wrote.

SOURCE:

The study was led by Tsai-Ling Liu, PhD, Center for Health System Sciences, Atrium Health in Charlotte, North Carolina. It was published online in JAMA Network Open.

LIMITATIONS:

The researchers reported potential selection and recall bias in both groups. Additional research is needed to find areas of improvement and assess the effects on clinician groups and health systems, they said.

DISCLOSURES:

Andrew McWilliams, MD, MPH, reported receiving grants from the Agency for Healthcare Research Quality, the National Institutes of Health, and the Duke Endowment unrelated to this work. Ajay Dharod, MD, reported his role as an electronic health record consultant for the Association of American Medical College CORE program. Jeffrey Cleveland, MD, disclosed his participation on the Executive Client Council, a noncompensated advisory group, for Nuance/Microsoft.

TOPLINE:

Reports of blood and lymphatic disorders were higher in pediatric patients treated with Janus kinase (JAK) inhibitors than in adults in a review of US and Canadian adverse event (AE) data, which also found that acne was the most common skin-related AE in children, and serious AEs were less common.

METHODOLOGY:

• Researchers analyzed 399,649 AEs in 133,216 adult patients and 2883 AEs in 955 pediatric patients (age, < 18 years) from November 2011 to February 2023 using the US Food and Drug Administration Adverse Event Reporting System and the Canada Vigilance Adverse Reaction Online Database.
• AEs were categorized on the basis of the Medical Dictionary for Regulatory Activities system organ class.
• Five JAK inhibitors approved for use in children were included in the study: Baricitinib, upadacitinib, abrocitinib, ruxolitinib, and tofacitinib.

TAKEAWAY:

• The most frequently reported AEs in children were blood and lymphatic system disorders, including neutropenia, thrombocytopenia, and anemia (24%); viral, fungal, and bacterial infections, such as pneumonia and sepsis (17.2%); constitutional symptoms and administrative concerns, including pyrexia and fatigue (15.7%); gastrointestinal disorders, such as vomiting and abdominal pain (13.6%); and respiratory disorders, such as cough and respiratory distress (5.3%).
• In adults, the most common AEs were viral, fungal, and bacterial infections (16.8%); constitutional symptoms and administrative concerns (13.5%); musculoskeletal and connective tissue disorders (7.04%); and gastrointestinal (5.8%) and nervous system (5%) disorders.
• Acne (30.6%), atopic dermatitis (22.2%), and psoriasis (16.7%) were the most common skin and subcutaneous tissue AEs reported in children. Skin and subcutaneous AEs were more common with upadacitinib (21.1%), abrocitinib (9.1%), and tofacitinib (6.3%) in children.
• Serious AEs included in the boxed warning for JAK inhibitors — serious infection, mortality, malignancy, cardiovascular events, and thrombosis — were similar for baricitinib in children (4 of 49 patients, 8.2%) and adults (325 of 3707, 8.8%). For other JAK inhibitors, absolute numbers of these AEs in children were small and rates were lower in children than in adults.

IN PRACTICE:

“This information can support customized treatment and minimize the potential for undesired or intolerable AEs,” the authors wrote.

SOURCE:

This study was led by Sahithi Talasila, BS, Sidney Kimmel Medical College, Thomas Jefferson University, Philadelphia, and was published online in Pediatric Dermatology.

LIMITATIONS:

Pharmacovigilance registries did not fully capture the complete range of AEs because of potential reporting bias or recall bias. Additionally, events lacking sufficient objective evidence were underreported, while common AEs associated with JAK inhibitor therapy were overreported.

DISCLOSURES:

No specific funding sources for the study were reported. One author reported being a consultant, one reported serving as a principal investigator in clinical trials, and another reported serving on data and safety monitoring boards of various pharmaceutical companies.

The Food and Drug Administration (FDA) has approved atezolizumab and hyaluronidase-tqjs (Tecentriq Hybreza, Genentech) as a subcutaneous injection in adults, covering all approved indications of the intravenous (IV) formulation.

Approved indications include non–small cell lung cancer (NSCLC), SCLC, hepatocellular carcinoma, melanoma, and alveolar soft part sarcoma. Specific indications are available with the full prescribing information at Drugs@FDA.

This is the first programmed death–ligand 1 inhibitor to gain approval for subcutaneous administration.

“This approval represents a significant option to improve the patient experience,” Ann Fish-Steagall, RN, Senior Vice President of Patient Services at the LUNGevity Foundation stated in a Genentech press release.

Subcutaneous atezolizumab and hyaluronidase-tqjs was evaluated in the open-label, randomized IMscin001 trial of 371 adult patients with locally advanced or metastatic NSCLC who were not previously exposed to cancer immunotherapy and who had disease progression following treatment with platinum-based chemotherapy. Patients were randomized 2:1 to receive subcutaneous or IV administration until disease progression or unacceptable toxicity.

Atezolizumab exposure, the primary outcome measure of the study, met the lower limit of geometric mean ratio above the prespecified threshold of 0.8 (cycle 1C trough, 1.05; area under the curve for days 0-21, 0.87).

No notable differences were observed in overall response rate, progression-free survival, or overall survival between the two formulations, according to the FDA approval notice.

The confirmed overall response rate was 9% in the subcutaneous arm and 8% intravenous arm.

Adverse events of any grade occurring in at least 10% of patients were fatigue, musculoskeletal pain, cough, dyspnea, and decreased appetite.

The recommended dose for subcutaneous injection is one 15 mL injection, which contains 1875 mg of atezolizumab and 30,000 units of hyaluronidase.

Injections should be administered in the thigh over approximately 7 minutes every 3 weeks. By contrast, IV administration generally takes 30-60 minutes.

Approved indications include non–small cell lung cancer (NSCLC), SCLC, hepatocellular carcinoma, melanoma, and alveolar soft part sarcoma. Specific indications are available with the full prescribing information at Drugs@FDA.

This is the first programmed death–ligand 1 inhibitor to gain approval for subcutaneous administration.

“This approval represents a significant option to improve the patient experience,” Ann Fish-Steagall, RN, Senior Vice President of Patient Services at the LUNGevity Foundation stated in a Genentech press release.

Subcutaneous atezolizumab and hyaluronidase-tqjs was evaluated in the open-label, randomized IMscin001 trial of 371 adult patients with locally advanced or metastatic NSCLC who were not previously exposed to cancer immunotherapy and who had disease progression following treatment with platinum-based chemotherapy. Patients were randomized 2:1 to receive subcutaneous or IV administration until disease progression or unacceptable toxicity.

Atezolizumab exposure, the primary outcome measure of the study, met the lower limit of geometric mean ratio above the prespecified threshold of 0.8 (cycle 1C trough, 1.05; area under the curve for days 0-21, 0.87).

No notable differences were observed in overall response rate, progression-free survival, or overall survival between the two formulations, according to the FDA approval notice.

The confirmed overall response rate was 9% in the subcutaneous arm and 8% intravenous arm.

Adverse events of any grade occurring in at least 10% of patients were fatigue, musculoskeletal pain, cough, dyspnea, and decreased appetite.

The recommended dose for subcutaneous injection is one 15 mL injection, which contains 1875 mg of atezolizumab and 30,000 units of hyaluronidase.

Injections should be administered in the thigh over approximately 7 minutes every 3 weeks. By contrast, IV administration generally takes 30-60 minutes.

The Food and Drug Administration (FDA) has approved the targeted interleukin-13 inhibitor lebrikizumab (Ebglyss) for the treatment of adults and children age 12 years and older who have moderate to severe atopic dermatitis (AD) that is not well controlled, despite treatment with topical prescription therapies.

The recommended initial starting dose of lebrikizumab consists of 500 mg (two 250 mg injections) at baseline and week 2, followed by 250 mg every 2 weeks until week 16 or later when adequate clinical response is achieved. Then, maintenance dosing is recommended with one monthly injection (250 mg every 4 weeks). Children aged 12-17 years must weigh at least 88 pounds (40 kg) to be eligible for lebrikizumab treatment.

According to a press release from Lilly, which has been developing lebrikizumab, approval was based on results from the ADvocate 1, ADvocate 2, and ADhere studies, which included over 1000 adults and children aged 12 and older with moderate to severe AD. The primary endpoint for these studies was evaluated at 16 weeks and measured clear or almost clear skin (IGA score of 0 or 1).

According to Lilly, 38% of people in ADvocate 1 and 2 who took lebrikizumab achieved clear or almost-clear skin at 16 weeks, compared with 12% of those in the placebo arm, and 10% experienced these results as early as 4 weeks. Of those treated with lebrikizumab who experienced clear or almost-clear skin at week 16, 77% maintained those results at 1 year on the once-monthly dose. In addition, on average, 43% of those on lebrikizumab experienced relief of itch at 16 weeks, compared with 12% of those on placebo, according to the press release. 

The most common side effects of lebrikizumab observed in the clinical trials include eye and eyelid inflammation, such as redness, swelling, and itching; injection-site reactions; and herpes zoster (shingles).

Lebrikizumab was approved in Japan in January 2024, and by the European Commission in 2023.

Diagnosis: Subungual bony exostosis

X-ray showed findings were consistent with subungual bony exostosis

Rady Children’s Hospital San Diego

The patient was referred to orthopedics for further evaluation and ultimately underwent excisional surgery. At her most recent follow-up visit with orthopedic surgery, her new nail was observed to be growing well.

Rady Children’s Hospital San Diego

Subungual exostosis, also known as Dupuytren’s exostosis, is a benign osteocartilaginous tumor that classically presents as a bony growth at the dorsal aspect of the distal phalanx of the great toe, near the nail bed. The pathogenesis remains unclear, but suggested etiologies include prior trauma, infection, and hereditary abnormalities.¹

Clinically, lesions can be painful and may be associated with skin ulceration. The location at the dorsal distal great toe is a key distinguishing feature. Physical exam reveals a firm, fixed nodule with a hyperkeratotic smooth surface.²

MiLo Studios

Radiographic evaluation, particularly with a lateral view, is often diagnostic. The classic radiographic finding in subungual exostosis is an osseous structure connected to the distal phalanx, with a hazy periphery representing a fibrocartilage cap.

Treatment involves complete marginal excision. The complications from surgical excision are minimal, with the most common being recurrence.³ However, the recurrence rate is also generally low, around 4%.¹

TOPLINE:

Pharmacy closures in the United States are creating “pharmacy deserts,” disproportionately affecting socially vulnerable communities. High social vulnerability and low primary care practitioner (PCP) density are linked to increased pharmacy desert density.

METHODOLOGY:

• Data through 2020 on communities located 10 or more miles from the nearest retail pharmacy were sourced from TelePharm Map.
• Counties were stratified as having a high pharmacy desert density if the number of pharmacy deserts per 1000 inhabitants was in the 80th percentile or higher.
• Social vulnerability index and healthcare practitioner data were obtained from the Agency for Toxic Substances and Disease Registry and the Area Health Resources Files.
• PCP density was calculated as the number of PCPs per 10,000 inhabitants.
• A total of 3143 counties were analyzed, with 1447 (46%) having at least one pharmacy desert.

TAKEAWAY:

• Counties with a high pharmacy desert density had a higher social vulnerability index than those with a low pharmacy desert density (P = .006).
• Areas with a high pharmacy desert density had lower median PCP density than those with low or no pharmacy desert density (P < .001).
• High social vulnerability index (odds ratio [OR], 1.35; 95% CI, 1.07-1.70; P = .01) and low PCP density (OR, 2.27; 95% CI, 1.80-2.86; P < .001) were associated with a higher likelihood for a county to have a high pharmacy desert density.
• Pharmacy closures are leaving more individuals without easy access to medications, with disproportionate consequences for certain communities.

IN PRACTICE:

“As high pharmacy desert density counties also have a lower PCP density, patients residing in these regions face increased barriers to accessing primary healthcare needs,” wrote the authors of the study.

SOURCE:

The study was led by Giovanni Catalano, MD, Muhammad Muntazir Mehdi Khan, MBBS, and Timothy M. Pawlik, MD, PhD, MPH, MTS, MBA, Department of Surgery, The Ohio State University Wexner Medical Center in Columbus, Ohio. It was published online in JAMA Network Open.

LIMITATIONS:

The cross-sectional design of the study limited the ability to draw causal inferences. The study relied on public county-level data, which may not have captured all relevant variables. The use of the social vulnerability index and PCP density as proxies did not fully represent the complexity of pharmacy access issues. The study’s findings were not generalizable to regions outside the United States.

DISCLOSURES:

No relevant conflicts of interest were disclosed by the authors. Additional disclosures are noted in the original article.

The University of Virginia (UVA) is defending the CEO of its health system and its medical school dean in the wake of a very public call for their removal.

At least 128 members of the University of Virginia faculty who are employed by both the medical school and the UVA Physicians Group wrote to the UVA Board of Visitors and its peer-elected faculty leaders, expressing no confidence in K. Craig Kent, MD, CEO of UVA Health and executive vice president for health affairs, and Melina Kibbe, MD, dean of the medical school and chief health affairs officer.

Dr. Kibbe, a vascular surgeon and researcher, is also the editor in chief of JAMA Surgery.

“We call for the immediate removal of Craig Kent and Melina Kibbe,” wrote the physicians.

The letter alleged that patient safety was compromised because doctors, nurses, and other staff were pressured to abstain from reporting safety concerns and that physicians had been hired “despite concerns regarding integrity and quality.” Those who raised safety concerns faced “explicit and implicit threats and retaliation,” including delays and denials of promotion and tenure, said the letter.

The September 5 letter did not include signatures. The authors said that names were being protected, but that they would share the names with a limited audience.

UVA President Jim Ryan took issue with the notion that the signees were anonymous. He said in his own letter to medical school faculty that some of the accusations were about matters that had already been addressed or that were being worked on. As far as allegations that he was not previously aware of, “we will do our best to investigate,” he said.

The faculty who signed the letter “have besmirched the reputations of not just Melina and Craig,” wrote Mr. Ryan. “They have unfairly — and I trust unwittingly — cast a shadow over the great work of the entire health system and medical school.”

The authors claimed that reports about bullying and harassment of trainees had been “suppressed, minimized, and subsequently altered.”

And they said that spending on leadership was prioritized over addressing clinical and technical staff shortages. Whistleblowers who reported fraud were not protected, and clinicians were pressured to modify patient records to “obfuscate adverse outcomes and boost productivity metrics,” they wrote.

The 128 members of the UVA Physicians Group who signed the letter represent about 10% of the 1400 medical school faculty members.

It is not the first time that Dr. Kent has been given a vote of no confidence. In 2017, when he was the dean of the College of Medicine at the Ohio State University, Dr. Kent was accused in a “no confidence” letter from 25 physicians and faculty of helping to undermine the school’s mission and taking actions that led to resignations and early retirements of many staff, the Columbus Dispatch reported.

William G. Crutchfield Jr., a member of the UVA Health System Board, defended Dr. Kent and Dr. Kibbe in a lengthy statement shared with this news organization. He said that UVA Health’s four hospitals had received “A” ratings for safety, and that the system has a 5.1% turnover rate compared with a national average of 8.3%.

Dr. Kent and Dr. Kibbe have recruited faculty from top academic medical centers, Mr. Crutchfield wrote.

“If our work environment were so toxic, these people would not have joined our faculty,” he wrote.

Mr. Crutchfield credited Dr. Kent and Dr. Kibbe with crafting a new 10-year strategic plan and for hiring a chief strategy officer to lead the plan — a move that replaced “expensive outside consultants.”

Mr. Ryan said in his letter that his inbox “is overflowing with testimonials from some of the 1200-plus faculty who did not sign the letter, who attest that the health system today — under Melina and Craig’s leadership — is in the best shape it has ever been in, and that they have addressed changes that have needed to be made for more than two decades.”

A request to see some of these positive testimonials was not answered by press time.

Mr. Crutchfield, like Mr. Ryan, said that the letter writers were doing more harm than good.

“If a small cabal of people hiding behind anonymity can force outstanding leaders out of UVA, it will make it extremely difficult to recruit outstanding new physicians, nurses, technicians, and administrators,” he wrote.

The letter alleged that patient safety was compromised because doctors, nurses, and other staff were pressured to abstain from reporting safety concerns and that physicians had been hired “despite concerns regarding integrity and quality.” Those who raised safety concerns faced “explicit and implicit threats and retaliation,” including delays and denials of promotion and tenure, said the letter.

The September 5 letter did not include signatures. The authors said that names were being protected, but that they would share the names with a limited audience.

UVA President Jim Ryan took issue with the notion that the signees were anonymous. He said in his own letter to medical school faculty that some of the accusations were about matters that had already been addressed or that were being worked on. As far as allegations that he was not previously aware of, “we will do our best to investigate,” he said.

The faculty who signed the letter “have besmirched the reputations of not just Melina and Craig,” wrote Mr. Ryan. “They have unfairly — and I trust unwittingly — cast a shadow over the great work of the entire health system and medical school.”

The authors claimed that reports about bullying and harassment of trainees had been “suppressed, minimized, and subsequently altered.”

And they said that spending on leadership was prioritized over addressing clinical and technical staff shortages. Whistleblowers who reported fraud were not protected, and clinicians were pressured to modify patient records to “obfuscate adverse outcomes and boost productivity metrics,” they wrote.

The 128 members of the UVA Physicians Group who signed the letter represent about 10% of the 1400 medical school faculty members.

It is not the first time that Dr. Kent has been given a vote of no confidence. In 2017, when he was the dean of the College of Medicine at the Ohio State University, Dr. Kent was accused in a “no confidence” letter from 25 physicians and faculty of helping to undermine the school’s mission and taking actions that led to resignations and early retirements of many staff, the Columbus Dispatch reported.

William G. Crutchfield Jr., a member of the UVA Health System Board, defended Dr. Kent and Dr. Kibbe in a lengthy statement shared with this news organization. He said that UVA Health’s four hospitals had received “A” ratings for safety, and that the system has a 5.1% turnover rate compared with a national average of 8.3%.

Dr. Kent and Dr. Kibbe have recruited faculty from top academic medical centers, Mr. Crutchfield wrote.

“If our work environment were so toxic, these people would not have joined our faculty,” he wrote.

Mr. Crutchfield credited Dr. Kent and Dr. Kibbe with crafting a new 10-year strategic plan and for hiring a chief strategy officer to lead the plan — a move that replaced “expensive outside consultants.”

Mr. Ryan said in his letter that his inbox “is overflowing with testimonials from some of the 1200-plus faculty who did not sign the letter, who attest that the health system today — under Melina and Craig’s leadership — is in the best shape it has ever been in, and that they have addressed changes that have needed to be made for more than two decades.”

A request to see some of these positive testimonials was not answered by press time.

Mr. Crutchfield, like Mr. Ryan, said that the letter writers were doing more harm than good.

“If a small cabal of people hiding behind anonymity can force outstanding leaders out of UVA, it will make it extremely difficult to recruit outstanding new physicians, nurses, technicians, and administrators,” he wrote.

TOPLINE:

Current use of hydroxychloroquine is associated with a lower risk for myocardial infarction (MI), stroke, and other thromboembolic events in patients with systemic lupus erythematosus (SLE). This protective effect diminishes after discontinuation of hydroxychloroquine treatment.

METHODOLOGY:

• Researchers used a nested case-control design to evaluate the association between exposure to hydroxychloroquine and the risk for cardiovascular events in patients with SLE.
• They included 52,883 adults with SLE (mean age, 44.23 years; 86.6% women) identified from the National System of Health Databases, which includes 99% of the French population.
• Among these, 1981 individuals with composite cardiovascular conditions were matched with 16,892 control individuals without cardiovascular conditions.
• Patients were categorized on the basis of hydroxychloroquine exposure into current users (last exposure within 90 days before a cardiovascular event), remote users (91-365 days before), and nonusers (no exposure within 365 days).
• The study outcomes included a composite of cardiovascular events, including MI, stroke (including transient ischemic attack), and other thromboembolic events such as phlebitis, thrombophlebitis, venous thrombosis, venous thromboembolism, and pulmonary embolism.

TAKEAWAY:

• Current hydroxychloroquine users had lower odds of experiencing a composite cardiovascular outcome than nonusers (adjusted odds ratio [aOR], 0.63; 95% CI, 0.57-0.70).
• The odds of MI (aOR, 0.72; 95% CI, 0.60-0.87), stroke (aOR, 0.71; 95% CI, 0.61-0.83), and other thromboembolic events (aOR, 0.58; 95% CI, 0.48-0.69) were also lower among current users than among nonusers.
• No significant association was found for remote hydroxychloroquine exposure and the risk for composite cardiovascular events, MI, stroke, and other thromboembolic events.

IN PRACTICE:

“These findings support the protective association of hydroxychloroquine against CV [cardiovascular] events and underscore the importance of continuous hydroxychloroquine therapy for patients diagnosed with SLE,” the authors wrote.

SOURCE:

The study was led by Lamiae Grimaldi-Bensouda, PharmD, PhD, Department of Pharmacology, Hospital Group Paris-Saclay, Assistance Publique-Hôpitaux de Paris, France. It was published online on August 30, 2024, in JAMA Network Open.

LIMITATIONS:

The observational nature of the study may have introduced confounding. Current hydroxychloroquine users were younger than nonusers, with an average age difference of almost 5 years. Current hydroxychloroquine users had a twofold longer duration of onset of SLE and had a higher prevalence of chronic kidney disease compared with nonusers.

DISCLOSURES:

This study was funded by the Banque pour l’Investissement, Deeptech. Some authors declared having financial ties with various institutions and companies outside of the current study.

TOPLINE: 

Cannabis users aged 65 years or older undergoing general anesthesia for surgery required higher doses of inhalational anesthetics than nonusers. However, the clinical relevance of this difference remains unclear.

METHODOLOGY:

• To assess if cannabis use leads to higher doses of inhalational anesthesia during surgery, the researchers conducted a retrospective cohort study comparing the average intraoperative minimum alveolar concentrations of volatile anesthetics (isoflurane and sevoflurane) between older adults who used cannabis products and those who did not.
• The researchers reviewed electronic health records of 22,476 patients aged 65 years or older who underwent surgery at the University of Florida Health System between 2018 and 2020.
• Overall, 268 patients who reported using cannabis within 60 days of surgery (median age, 69 years; 35% women) were matched to 1072 nonusers.
• The median duration of anesthesia was 175 minutes.
• The primary outcome was the intraoperative time-weighted average of isoflurane or sevoflurane minimum alveolar concentration equivalents.

TAKEAWAY:

• Cannabis users had significantly higher average minimum alveolar concentrations of isoflurane or sevoflurane than nonusers (mean, 0.58 vs 0.54; mean difference, 0.04; P = .021).
• The findings were confirmed in a sensitivity analysis that revealed higher mean average minimum alveolar concentrations of anesthesia in cannabis users than in nonusers (0.57 vs 0.53; P = .029).
• Although the 0.04 difference in minimum alveolar concentration between cannabis users and nonusers was statistically significant, its clinical importance is unclear.

IN PRACTICE:

“While recent guidelines underscore the importance of universal screening for cannabinoids before surgery, caution is paramount to prevent clinical bias leading to the administration of unnecessary higher doses of inhalational anesthesia, especially as robust evidence supporting such practices remains lacking,” the authors of the study wrote.
 

SOURCE:

This study was led by Ruba Sajdeya, MD, PhD, of the Department of Epidemiology at the University of Florida, Gainesville, and was published online in August 2024 in Anesthesiology.

LIMITATIONS: 

This study lacked access to prescription or dispensed medications, including opioids, which may have introduced residual confounding. Potential underdocumentation of cannabis use in medical records could have led to exposure misclassification. The causality between cannabis usage and increased anesthetic dosing could not be established due to the observational nature of this study. 

DISCLOSURES:

This study was supported by the National Institute on Aging, the National Institutes of Health, and in part by the University of Florida Clinical and Translational Science Institute. Some authors declared receiving research support, consulting fees, and honoraria and having other ties with pharmaceutical companies and various other sources.
