Removing the FDA's Boxed Hepatotoxicity Warning and Liver Function Testing Requirement for Ambrisentan.

Importance: Endothelin receptor antagonists are first-line therapy for pulmonary arterial hypertension (PAH). The first 2 agents approved in the class, bosentan and ambrisentan, initially carried boxed warnings for hepatotoxicity and required monthly liver function tests (LFTs) as part of a risk evaluation and mitigation strategy (REMS); however, in 2011, as further safety data emerged on ambrisentan, the boxed hepatotoxicity warning and LFT requirements were removed. Objective: To analyze changes in the use of and LFT monitoring for ambrisentan and bosentan after changes to the ambrisentan labeling and REMS. Design, Setting, and Participants: This serial cross-sectional study used data from 3 longitudinal health care insurance claims databases-Medicaid, Optum's deidentified Clinformatics Data Mart, and Merative Marketscan-to perform an interrupted time series analysis of prescription fills and LFTs for patients taking ambrisentan and bosentan. Participants were patients filling prescriptions for ambrisentan and bosentan from July 1, 2007, to December 31, 2018. Data analysis was performed from April 2021 to August 2023. Exposure: Removal of the boxed warning for hepatotoxicity and the REMS LFT monitoring requirements on ambrisentan in March 2011. Main Outcomes and Measures: The primary outcomes were use of ambrisentan (ie, individuals with at least 1 dispensing per 1 000 000 individuals enrolled in the 3 datasets) vs bosentan and LFT monitoring (ie, proportion of initiators with at least 1 ordered test) before initiation and before the first refill. Results: A total of 10 261 patients received a prescription for ambrisentan during the study period (7442 women [72.5%]; mean [SD] age, 52.6 [17.6] years), and 11 159 patients received a prescription for bosentan (7931 women [71.1%]; mean [SD] age, 47.7 [23.7] years). Removal of the ambrisentan boxed hepatotoxicity warning and LFT monitoring requirement was associated with an immediate increase in the use of ambrisentan (1.50 patients per million enrollees; 95% CI, 1.08 to 1.92 patients per million enrollees) but no significant change in the use of bosentan. There were reductions in recorded LFTs before drug initiation (13.1% absolute decrease; 95% CI, -18.2% to -8.0%) and before the first refill (26.4% absolute decrease; 95% CI, -34.4% to -18.5%) of ambrisentan but not bosentan. Conclusions and Relevance: In this serial cross-sectional study of ambrisentan, labeling changes and removal of the REMS-related LFT requirement were associated with shifts in prescribing and testing behavior for ambrisentan but not bosentan. Further clinician education may be needed to maximize the benefits of REMS programs and labeling warnings designed to ensure the safe administration of high-risk medications.

The Clinical Utility of a 7-Gene Biosignature on Radiation Therapy Decision Making in Patients with Ductal Carcinoma In Situ Following Breast-Conserving Surgery: An Updated Analysis of the DCISionRT® PREDICT Study.

BACKGROUND: Breast-conserving surgery (BCS) followed by adjuvant radiotherapy (RT) is a standard treatment for ductal carcinoma in situ (DCIS). A low-risk patient subset that does not benefit from RT has not yet been clearly identified. The DCISionRT test provides a clinically validated decision score (DS), which is prognostic of 10-year in-breast recurrence rates (invasive and non-invasive) and is also predictive of RT benefit. This analysis presents final outcomes from the PREDICT prospective registry trial aiming to determine how often the DCISionRT test changes radiation treatment recommendations. METHODS: Overall, 2496 patients were enrolled from February 2018 to January 2022 at 63 academic and community practice sites and received DCISionRT as part of their care plan. Treating physicians reported their treatment recommendations pre- and post-test as well as the patient's preference. The primary endpoint was to identify the percentage of patients where testing led to a change in RT recommendation. The impact of the test on RT treatment recommendation was physician specialty, treatment settings, individual clinical/pathological features and RTOG 9804 like criteria. Multivariate logisitc regression analysis was used to estimate the odds ratio (ORs) for factors associated with the post-test RT recommendations. RESULTS: RT recommendation changed 38% of women, resulting in a 20% decrease in the overall recommendation of RT (p < 0.001). Of those women initially recommended no RT (n = 583), 31% were recommended RT post-test. The recommendation for RT post-test increased with increasing DS, from 29% to 66% to 91% for DS <2, DS 2-4, and DS >4, respectively. On multivariable analysis, DS had the strongest influence on final RT recommendation (odds ratio 22.2, 95% confidence interval 16.3-30.7), which was eightfold greater than clinicopathologic features. Furthermore, there was an overall change in the recommendation to receive RT in 42% of those patients meeting RTOG 9804-like low-risk criteria. CONCLUSIONS: The test results provided information that changes treatment recommendations both for and against RT use in large population of women with DCIS treated in a variety of clinical settings. Overall, clinicians changed their recommendations to include or omit RT for 38% of women based on the test results. Based on published clinical validations and the results from current study, DCISionRT may aid in preventing the over- and undertreatment of clinicopathological 'low-risk' and 'high-risk' DCIS patients.

Tramadol use in U.S. Adults With Commercial Health Insurance, 2005-2021.

INTRODUCTION: Tramadol has been associated with chronic opioid use and emergency room (ER) visits. However, little is known about trends in prescription tramadol use in the U.S. METHODS: Optum's de-identified Clinformatics® Data Mart Database was used to assess trends in monthly incident and prevalent tramadol use from 2005 to 2021, stratified by sex and age (18-64 vs. ≥65 years). State-specific trends following scheduling of tramadol as Class IV controlled substance in August 2014 were analyzed with random effects regression models. Demographics, comorbidities, initiation setting, dose, and co-dispensing with other opioids and central nervous system (CNS) agents were assessed in people initiating tramadol, stratified by age and initiation year (2005-2010, 2011-2015, 2016-2021). Analyses were performed in 2023 and 2024. RESULTS: During 2005-2021, the mean percentage using tramadol in a given month was 0.88% of younger females, 0.55% of younger males, 1.97% of older females, and 1.14% of older males; 5,729,652 initiations were identified. Since 2014, estimated relative yearly decrease was 4% (95% CI 3%; 5%) in use and 5% (95% CI 4%; 5%) in initiation, with variation across states. Primary care percentage of tramadol initiations declined from 49.2% in 2005-2010 to 37.2% in 2016-2021. During 2016-2021, co-dispensing with other CNS agents occurred in 37.8% of younger and 32.1% of older adults initiating tramadol. CONCLUSIONS: Tramadol use was higher in females and older adults, exhibited heterogeneous trends across states, and shifted from primary care to ER and specialist settings over time. Co-dispensing with other CNS agents was common and warrants further monitoring.

Medicare Should Cover Weight Loss Drugs as Long as the Prices are Affordable.

Glucagon-like peptide-1 receptor agonists are effective for treating obesity, but the high cost of these medications endangers the financial viability of our health care system. To ensure that these drugs are available to Medicare beneficiaries, pharmaceutical manufacturers must lower their prices.

Reactivation After Teprotumumab Treatment for Active Thyroid Eye Disease.

PURPOSE: To determine the recurrence and reactivation rates after teprotumumab therapy for active thyroid eye disease. DESIGN: Retrospective consecutive case series. METHODS: This was a study of all patients followed for active thyroid eye disease at the Cole Eye Institute, Cleveland Clinic, treated with teprotumumab between May 2020 and May 2021. Patients with less than 6 months follow-up after completion of infusions were excluded. The primary outcome measure was reactivation, defined as a regression in proptosis (increase of ≥2 mm in either eye and to within ≤2 mm of pre-treatment level and Clinical Activity Score [CAS] worsening of 2 points or greater). Secondary outcome was diplopia response. RESULTS: A total of 21 patients were included in the study. The average long-term improvement in proptosis in the eye with more proptosis after teprotumumab was 1.57mm (range, -3 to 4 mm). Of the 17 initial responders, there were 8 reactivations (47%) and 2 isolated proptosis regressions (12%); Overall, 7 of 21 patients (33%) responded throughout the study period. Average time to regression was 12.25 months (range, 2-22.5 months). There was no statistically significant change in diplopia at final visit in any subgroup (P = 0.68 to >.99). CONCLUSIONS: At most, 33% of patients demonstrate continued response 2 years after teprotumumab treatment. The proptosis and CAS regression occurs in the setting of disease reactivation in 80% of regressions. Teprotumumab treatment appears to offer minimal long-term improvement in diplopia.

Changes in Induced Medical and Procedural Abortion Rates in a Commercially Insured Population, 2018 to 2022 : An Interrupted Time-Series Analysis.

BACKGROUND: During the COVID-19 pandemic, access to in-person care was limited, and regulations requiring in-person dispensing of mifepristone for medical abortions were relaxed. The effect of the pandemic and accompanying regulatory changes on abortion use is unknown. OBJECTIVE: To estimate changes in the incidence rate of induced medical and procedural abortions. DESIGN: Serial cross-sectional study with interrupted time-series analyses. SETTING: Commercially insured persons in the United States. PARTICIPANTS: Reproductive-aged women. INTERVENTION: Onset of the COVID-19 pandemic in March 2020 and subsequent regulatory changes affecting the in-person dispensing requirement for mifepristone. MEASUREMENTS: Monthly age-adjusted incidence rates of medical and procedural abortions were measured among women aged 15 to 44 years from January 2018 to June 2022. Medical abortions were classified as in-person or telehealth. Linear segmented time-series regression was used to calculate changes in abortion rates after March 2020. RESULTS: In January 2018, the estimated age-adjusted monthly incidence rate of abortions was 151 per million women (95% CI, 142 to 161 per million women), with equal rates of medical and procedural abortions. After March 2020, there was an immediate 14% decrease in the monthly incidence rate of abortions (21 per million women [CI, 7 to 35 per million women]; P = 0.004), driven by a 31% decline in procedural abortions (22 per million women [CI, 16 to 28 per million women]; P < 0.001). Fewer than 4% of medical abortions each month were administered via telehealth. LIMITATION: Only abortions reimbursed by commercial insurance were measured. CONCLUSION: The incidence rate of procedural abortions declined during the COVID-19 pandemic, and this lower rate persisted after other elective procedures rebounded to prepandemic rates. Despite removal of the in-person dispensing requirement for mifepristone, the use of telehealth for insurance-covered medical abortions remained rare. Amid increasing state restrictions, commercial insurers have the opportunity to increase access to abortion care, particularly via telehealth.

An unusual presentation of Pseudomonas citronellolis bacteraemia and Campylobacter gastroenteritis infection in a human - a case report and literature review.

Introduction: Pseudomonas citronellolis is an unusual pathogen in humans and has not been extensively described in the scientific literature. Herein, we present a case of bacteremia and septic shock due to Pseudomonas citronellolis following Campylobacter species gastroenteritis in a patient with immunosuppression. Case Presentation: An 80-year-old man with myeloproliferative disorder on ruxolitinib presented with several days of worsening abdominal pain, which rapidly developed into septic shock with multi-organ failure and explosive diarrhea. Gram-negative bacilli observed on Gram staining of his blood culture broth were later identified as Pseudomonas citronellolis and Bacteroides thetaiotaomicron . Repeated abdominal imaging revealed no evidence of intestinal perforation or megacolon. In addition, stool PCR was positive for Campylobacter species. His clinical course improved after 14 days of meropenem with complete resolution of his symptoms and organ failure. Conclusion: P. citronellolis is a rare infection in humans. We postulate that Janus Associated Kinase (JAK) inhibition in myeloproliferative disorders heightened this patient's risk of bacterial translocation and severe illness in the setting of Campylobacter gastroenteritis. P. citronellolis may be identified more frequently as a pathogen in humans as more advanced diagnostic technologies become increasingly available in clinical microbiology.

Metastatic gastric carcinoma to the eyelids masquerading as a chalazion: A case report.

Purpose: To describe an unusual case of metastatic gastric adenocarcinoma involving the eyelids and anterior orbit. Observations: An 82-year-old female with prior diagnosis of locally metastatic gastric adenocarcinoma developed eyelid edema. Initial ophthalmic assessment suggested presence of a chalazion that did not resolve with medical management. A few weeks after initial evaluation, the eyelid and facial edema worsened. Eyelid skin biopsy showed only inflammatory changes, but inflammatory work up was unrevealing and there was poor response to steroid therapy. Orbitotomy with biopsy ultimately revealed involvement of eyelid skin by a signet ring cell metastatic gastric carcinoma. Conclusions and importance: Eyelid and orbital metastasis from gastric adenocarcinoma may present mainly with inflammatory signs and symptoms masquerading as a chalazion. This case highlights the spectrum of presentation of this rare periocular metastasis.

Conjunctival Müllerectomy With or Without Tarsectomy Using Absorbable Versus Nonabsorbable Suture.

PURPOSE: To compare the outcomes of blepharoptosis repair using conjunctival Müllerectomy with or without tarsectomy (CM±T) using absorbable suture versus nonabsorbable suture. METHODS: Retrospective case-series of all consecutive cases of CM±T ptosis repair between January 1, 2019, and August 31, 2021. Patients were placed in groups based on whether they had absorbable or nonabsorbable suture used during their procedure. Preoperative and postoperative measurements of MRD1 were gathered in both groups, and information on patient satisfaction, symmetry, complications, and reoperations. RESULTS: Ninety-two patients had surgery using nonabsorbable suture and 96 patients had surgery using absorbable suture, with average age of 72.0 and 70.9 years, respectively ( p = 0.488). When comparing nonabsorbable to absorbable suture, the groups did not differ on average preoperative MRD1 (1.11 mm [±0.96] vs. 0.96 mm [±0.86]; p = 0.161), average postoperative MRD1 (3.18 mm [±0.54] vs. 3.20 mm (±0.51); p = 0.736) or average MRD1 improvement (2.09 mm (±0.86) vs. 2.25 mm (±0.79); p = 0.089). Goal MRD1 was achieved in 85.3% of nonabsorbable cases and 82.8% of absorbable cases ( p = 0.562) and the rate of reoperation between groups was not significant ( p = 0.63). Good postoperative symmetry was noted in 91.6% of nonabsorbable and 91.0% absorbable suture cases ( p = 0.83). No difference in the number of complications was noted between groups ( p = 0.88), including need for contact lens placement (2.7% nonabsorbable, 1.3% absorbable; p = 0.37). CONCLUSIONS: The use of absorbable suture was found to have predictable and effective outcomes similar to cases using nonabsorbable suture for CM±T without an increase in complications or rate or reoperation.
