ABSTRACT

BACKGROUND: Mercaptopurine is an important component of acute lymphoblastic leukemia (ALL) and lymphoma (LLy) maintenance therapy. The 6-thioguanine nucleosides (6-TGN) are believed to be the primary contributor to myelosuppression and immunosuppressive effects, while 6-methylmercaptopurine (6-MMPN) is believed to be responsible for several toxicities including hepatotoxicity, pancreatitis, and hypoglycemia. Previous reports suggest the addition of allopurinol may reduce these toxicities.

AIMS: To assess the use of allopurinol to improve both safety and efficacy of mercaptopurine in pediatric patients with ALL and LLy during maintenance therapy. Secondary objectives included evaluating patient tolerability and skewed metabolism. In addition, we also analyzed mercaptopurine daily dose reduction upon allopurinol initiation.

METHODS AND RESULTS: The primary endpoint was time within goal ANC prior to and after initiation of allopurinol. Secondary endpoints included; improvement in selective toxicities (hepatotoxicity, pancreatitis, and hypoglycemia) and 6-MMPN to 6-TGN ratio prior to and after allopurinol initiation. In addition, an exploratory endpoint assessing mercaptopurine daily dose reduction prior to and after allopurinol initiation was included. Sixteen patients met inclusion criteria and 15 (94%) of which were included in this study. Median percent of maintenance days within goal ANC prior to and after initiation of allopurinol was 27.8 (IQR 22.6-44.9) and 41.6 (IQR 20.2-58.2) respectively. All patients experienced selective toxicities; 15 (100%) hepatotoxicity, 1 (7%) pancreatitis, and 3 (20%) hypoglycemia. Improvement of toxicities was seen in 13/15 (87%), 1/1 (100%), and 2/3 (67%) respectively. Average 6-MMPN:6-TGN ratio prior to allopurinol initiation was 304:1 and after, allopurinol initiation improved to 15:1, resulting in a 95% reduction. Average mercaptopurine dose prior to and after allopurinol initiation decreased by about 56% (63 to 28 mg/m2 /day).

CONCLUSION: Results suggest that the use of allopurinol in pediatric patients with ALL and LLy receiving mercaptopurine during maintenance therapy is both safe and effective.

ABSTRACT

INTRODUCTION: The role of curcuminoids, a striking antioxidant, in prevention of contrast-induced acute kidney injury (CI-AKI) remains unknown. We aim to evaluate the efficacy and safety of curcuminoids in preventing CI-AKI in patients undergoing elective coronary angiography (CAG) and/or percutaneous coronary intervention (PCI).

METHODS: We randomized 114 patients who were undergoing elective CAG and/or PCI to receive curcuminoids, 4 grams/day (1 day before, and 1 day after the procedure, n=56) or placebo (n=58). Serum creatinine was assessed at baseline, 12, 24 and 48 hours after contrast exposure. The primary endpoint was development of CI-AKI defined as serum creatinine increase ≥0.3 mg/dL within 48 hours after contrast exposure. The secondary endpoint was the occurrence of kidney injury defined by >30% increase in urine neutrophil gelatinase-associated lipocalin (NGAL).

RESULTS: Baseline characteristics were comparable between the two groups. Seven (12.7%) in curcuminoids group and eight (14.0%) in placebo group developed CI-AKI (p=0.84). The incidence of increased urine NGAL was comparable in the placebo and curcuminoids groups (39.6% vs. 50%, respectively; p=0.34). None in both groups had drug-related adverse events.

CONCLUSION: This is a pilot study to demonstrate the safety and tolerability of curcuminoids in patients undergoing elective CAG and/or PCI. Curcuminoids have no protective effects against kidney injury after elective CAG and/or PCI.

ABSTRACT

OBJECTIVE: To evaluate the efficacy and safety of 96 weeks of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) treatment in participants switching from dolutegravir (DTG)-based therapy.

DESIGN: Studies 1489 (NCT02607930) and 1490 (NCT02607956) were phase 3 randomized, double-blind, active-controlled, first-line therapy trials in people with HIV-1. After 144 weeks of DTG-based or B/F/TAF treatment, participants could enter a 96-week open-label extension (OLE) of B/F/TAF.

METHODS: A pooled analysis evaluated viral suppression (HIV-1 RNA <50 copies/mL) and changes in CD4+ cell count at OLE Weeks 48 and 96, treatment-emergent resistance, safety and tolerability after switch from a DTG-based regimen to B/F/TAF. Outcomes by prior treatment were summarized using descriptive statistics and compared by two-sided Wilcoxon rank sum test.

RESULTS: At OLE Week 96, participants who switched to B/F/TAF (N=519) maintained high levels of virologic suppression (99.5% and 99.1% in those switching from DTG/abacavir/lamivudine and DTG+F/TAF, respectively) and CD4+ cell count, with no treatment-emergent resistance to B/F/TAF. Twenty-one participants experienced drug-related adverse events (AEs) after switching, with diarrhea, weight gain and headache occurring most commonly. There were no cases of proximal renal tubulopathy, drug-related Grade 4 AEs or serious AEs. Two participants discontinued B/F/TAF due to treatment-related AEs. Participants who switched from DTG/abacavir/lamivudine experienced statistically significant greater weight gain than those who switched from DTG+F/TAF; however, median weight change from the blinded phase baseline to OLE Week 96 was numerically similar across treatment groups.

CONCLUSIONS: This medium-term analysis demonstrates the safety and efficacy of switching to B/F/TAF from a DTG-containing regimen in people with HIV-1.

ABSTRACT

BACKGROUND: People with gender dysphoria are treated with hormone therapy for gender reassignment. The indication of this therapy was initially for the opposite sex, and information on potential adverse drug reaction (ADR) is lacking.

OBJECTIVE: To describe ADR associated with gender transition medication in transgender individuals reported to the US Food and Drug Administration Adverse Event Reporting System (FAERS) database.

METHODS: Data from the FAERS database up to June 2023 were examined, focusing on reports of gender transition medication use in the context of gender dysphoria. The ADRs were categorized using the Medical Dictionary for Regulatory Activities at both Preferred Term and System Organ Class (SOC) levels. Descriptive statistics summarized report counts, medication types, indications, and ADR severity.

RESULTS: For individuals assigned female at birth undergoing gender transition to male (transgender men), 82 reports (230 ADRs) were analyzed, with an average age of 29.5 years. Transgender hormonal therapy was cited in 72% of reports, predominantly from the United States (67.1%). A striking 88% were categorized as serious ADRs, primarily SOC injury, poisoning, and procedural complications (26.5%), followed by psychiatric disorders (14.8%) and nervous system disorders (12.2%). Among those assigned sex male at birth transitioning to female (transgender women) (81 reports, 237 ADRs), mean age was 33.3 years, with 58% indicating use for gender dysphoria. A significant proportion (53.6%) were serious ADRs, primarily SOC: injury, poisoning, and procedural complications (26.6%).

CONCLUSIONS AND RELEVANCE: The FAERS data reveal significant ADRs in transgender individuals using hormone therapy, sometimes unintended for their recipient gender. Population-level studies are crucial to enhance transgender health care. Spontaneous surveillance databases like FAERS illuminate off-label ADRs, urging health care providers to approach hormone therapies with informed caution.

ABSTRACT

BACKGROUND: Recent advances in the management of pancreatic neuroendocrine tumors (pNETs) highlight the potential benefits of temozolomide, an alkylating agent, for these patients. In this meta-analysis, we aimed to assess the outcome of temozolomide, alone or in combination with other anticancer medications in patients with advanced pNET.

METHODS: Online databases of PubMed, Web of Science, Embase, the Cochrane Library, and ClinicalTrials.gov were searched systematically for clinical trials that reported the efficacy and safety of temozolomide in patients with advanced pNET. Random-effect model was utilized to estimate pooled rates of outcomes based on Response Evaluation Criteria in Solid Tumors criteria, biochemical response, and adverse events (AEs).

RESULTS: A total of 14 studies, providing details of 441 individuals with advanced pNET, were included. The quantitative analyses showed a pooled objective response rate (ORR) of 41.2% (95% confidence interval, CI, of 32.4%-50.6%), disease control rate (DCR) of 85.3% (95% CI of 74.9%-91.9%), and a more than 50% decrease from baseline chromogranin A levels of 44.9% (95% CI of 31.6%-49.0%). Regarding safety, the results showed that the pooled rates of nonserious AEs and serious AEs were 93.8% (95% CI of 88.3%-96.8%) and 23.7% (95% CI of 12.0%-41.5%), respectively. The main severe AEs encompassed hematological toxicities.

CONCLUSIONS: In conclusion, our meta-analysis suggests that treatment with temozolomide, either as a monotherapy or in combination with other anticancer treatments might be an effective and relatively safe option for patients with advanced locally unresectable and metastatic pNET. However, additional clinical trials are required to further strengthen these findings. This study has been registered in PROSPERO (CRD42023409280).

ABSTRACT

In Thailand, resource limitations lead many multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) patients to use off-label immunosuppressants. This study assesses the efficacy and safety of rituximab (RTX) with a CD19-based reinfusion regimen among Thai MS and NMOSD patients. A retrospective review of patients at the Faculty of Medicine Siriraj Hospital from January 1994 to April 2023 was conducted. The primary outcome assessed was the change in annualized relapse rate (ARR) for patients using RTX for over a year. Secondary outcomes included changes in the Expanded Disability Status Scale (EDSS) scores, time to the first relapse after RTX initiation for patients using RTX for over a year, and an evaluation of the safety of RTX. The study encompassed 36 MS and 39 NMOSD patients. A majority of patients (91.7% of MS and 79.5% of NMOSD) experienced no relapses during a median follow-up of 30 months (Interquartile range [IQR] 20-46) and 31 months (IQR 23-41), respectively. The median ARR significantly decreased in both MS (from 0.77 [IQR 0.42-1.83] to 0 [IQR 0-0], p < 0.001) and NMOSD (from 0.92 [IQR 0.68-1.78] to 0 [IQR 0-0.17], p < 0.001) patients after switching to RTX, with no difference between those following a fixed 6-month time point regimen and a CD19-based reinfusion regimen. Median EDSS scores improved significantly at the last follow-up visit in both groups. The mean time to the first subsequent relapse was 8.3 ± 3.0 months in MS and 6.8 ± 1.7 months in NMOSD. Mild adverse drug reactions occurred in 44% of patients. RTX effectively prevents relapses in Thai MS and NMOSD patients, with no observed serious adverse drug reactions.

ABSTRACT

CONTEXT: Potentially inappropriate prescribing of medications in older adults, particular those with dementia, can lead to adverse drug events including falls and fractures, worsening cognitive impairment, emergency department visits, and hospitalizations. Educational mailings from health plans to patients and their providers to encourage deprescribing conversations may represent an effective, low-cost, "light touch", approach to reducing the burden of potentially inappropriate prescription use in older adults with dementia.

OBJECTIVES: The objective of the Developing a PRogram to Educate and Sensitize Caregivers to Reduce the Inappropriate Prescription Burden in Elderly with Alzheimer's Disease (D-PRESCRIBE-AD) trial is to evaluate the effect of a health plan based multi-faceted educational outreach intervention to community dwelling patients with dementia who are currently prescribed sedative/hypnotics, antipsychotics, or strong anticholinergics.

METHODS: The D-PRESCRIBE-AD is an open-label pragmatic, prospective randomized controlled trial (RCT) comparing three arms: 1) educational mailing to both the health plan patient and their prescribing physician (patient plus physician arm, n = 4814); 2) educational mailing to prescribing physician only (physician only arm, n = 4814); and 3) usual care (n = 4814) among patients with dementia enrolled in two large United States based health plans. The primary outcome is the absence of any dispensing of the targeted potentially inappropriate prescription during the 6-month study observation period after a 3-month black out period following the mailing. Secondary outcomes include dose-reduction, polypharmacy, healthcare utilization, mortality and therapeutic switching within targeted drug classes.

CONCLUSION: This large pragmatic RCT will contribute to the evidence base on promoting deprescribing of potentially inappropriate medications among older adults with dementia. If successful, such light touch, inexpensive and highly scalable interventions have the potential to reduce the burden of potentially inappropriate prescribing for patients with dementia.

ABSTRACT

Electronic health records (EHRs) provide meaningful knowledge of drug-related adverse events (AEs) that are not captured in standard drug development and postmarketing surveillance. Using variables obtained from EHR data in the University of California San Francisco de-identified Clinical Data Warehouse, we aimed to evaluate the potential of machine learning to predict two hematological AEs, thrombocytopenia and anemia, in a cohort of patients treated with linezolid for 3 or more days. Features for model input were extracted at linezolid initiation (index), and outcomes were characterized from index to 14 days post-treatment. Random forest classification (RFC) was used for AE prediction, and reduced feature models were evaluated using cumulative importance (cImp) for feature selection. Grade 3+ thrombocytopenia and anemia occurred in 31% of 2,171 and 56% of 2,170 evaluable patients, respectively. Of the total 53 features, as few as 7 contributed at least 50% cImp, resulting in prediction accuracies of 70% or higher and area under the receiver operating characteristic curves of 0.886 for grade 3+ thrombocytopenia and 0.759 for grade 3+ anemia. Sensitivity analyses in strictly defined patient subgroups revealed similarly high predictive performance in full and reduced feature models. A logistic regression model with the same 50% cImp features showed similar predictive performance as RFC and good concordance with RFC probability predictions after isotonic calibration, adding interpretability. Collectively, this work demonstrates potential for machine learning prediction of AE risk in real-world patients using few variables regularly available in EHRs, which may aid in clinical decision making and/or monitoring.

ABSTRACT

BACKGROUND: Medication adherence is a prerequisite to achieving beneficial treatment outcomes. In major depressive disorder, many patients fail to complete medication regimens, raising concern for poor treatment outcomes. It is usual to experience adverse drug reactions (ADRs) while taking antidepressants, and relative discomfort is reported by patients.

AIMS: The present review focuses on the presence of antidepressant-related side effects and the subsequent relationship with medication non-adherence.

METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. Following the preliminary research, the research question and eligibility criteria were created based on the PICO framework. All articles retrieved from the selected databases were exported to Covidence, a Systematic Review managing software tool. Two reviewers assessed the papers to identify the risk of bias using the Joanna Briggs Institute critical appraisal tool for cross-sectional studies. Seven studies with a low-moderate risk of bias fulfilled the eligibility criteria and were conducted from 2013 to 2020 in Europe, Africa and Asia.

RESULTS: The results demonstrated high levels of suboptimal adherence ranging from 46% to 83% amongst the studied population. A variety of side effects were reported by a significant number of participants predominantly with moderate severity. A correlation between the presence of ADRs and suboptimal rates of adherence to antidepressants was found. Somnolence and headaches among other unspecified ADRs were found to increase the dropout rates for selective serotonin reuptake inhibitors.

CONCLUSIONS: The present study elucidates the need for effective interventions to facilitate antidepressant adherence and enhance doctor-patient communication, benefiting both the individuals and the healthcare system and leading to better clinical outcomes and reduction of relapse-related costs.

ABSTRACT

Ocrelizumab is an anti-CD20 monoclonal antibody used to treat primary progressive and relapsing-remitting multiple sclerosis. Several prior case reports have demonstrated colitis in association with ocrelizumab infusion, and one case report has shown ocrelizumab-associated diverticulitis. We report on two cases in which ocrelizumab treatment of multiple sclerosis was complicated by acute diverticulitis. A 50-year-old woman and a 41-year-old man, both with relapsing-remitting multiple sclerosis, presented with acute abdominal pain. One patient had no known gastrointestinal history while the other had a history of laparoscopic sleeve gastrectomy. Both patients had received an ocrelizumab infusion one month prior to presentation. The woman underwent exploratory laparotomy, which revealed perforated sigmoid diverticulitis. The man was initially suspected of appendicitis and was treated with appendectomy, but a pathology review demonstrated diverticular disease in the appendix. In patients with multiple sclerosis on ocrelizumab, presentation with diverticulitis should include ocrelizumab-induced diverticulitis in the differential diagnosis.

ABSTRACT

BACKGROUND: Pain is a common and very distressing symptom for adults and children with cancer. Compared with other routes of delivery, infusing pain medication directly into the intrathecal space around the spinal cord may reduce the incidence of systemic side effects and allow for more rapid and effective pain relief. We conducted a health technology assessment of intrathecal drug delivery systems (IDDSs) for adults and children with cancer pain, which included an evaluation of effectiveness, safety, cost-effectiveness, the budget impact of publicly funding IDDSs, patient preferences and values, and ethical considerations.

METHODS: We performed a systematic literature search of the clinical evidence to retrieve systematic reviews, and we selected and reported results from 2 recent reviews that were relevant to our research questions. We complemented the chosen systematic reviews with a literature search to identify primary studies published after December 2020. We used the Risk of Bias in Systematic Reviews (ROBIS) tool to assess the risk of bias of each included systematic review. We assessed the quality of the body of evidence according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group criteria. We performed a systematic economic literature search and conducted a cost-effectiveness analysis comparing IDDSs with standard care (i.e., non-IDDS methods of pain management) from a public payer perspective. We also analyzed the budget impact of publicly funding IDDSs in Ontario. To contextualize the potential value of IDDSs, we spoke with patients with cancer pain and with caregivers of patients with cancer pain. We explored ethical considerations from a review of published literature on the use of IDDSs for the management of cancer pain in adults and children as well as a review of the other components of this health technology assessment to identify ethical considerations relevant to the Ontario context.

RESULTS: We included 2 systematic reviews (1 on adults and 1 on children) in the clinical evidence review. In adults with cancer pain who have a life expectancy greater than 6 months, intrathecal drug delivery was associated with a significant reduction in pain intensity compared with before implantation up to a 1-year follow-up (GRADE: Moderate to Low). Improved pain management appeared to be maintained beyond a 4-week follow-up. IDDSs likely decrease the use of systemic opioids (GRADE: Moderate to Low). They may also improve health-related quality of life (GRADE: Low), functional outcomes (GRADE: Low), and survival (GRADE: Low to Very low). In children with cancer pain, IDDSs may reduce pain intensity, improve functional outcomes, and improve survival, but the evidence is very uncertain (all GRADEs: Very low). IDDS implantation carries certain rare risks related to mechanical errors, drug-related side effects, and surgical complications. There are inherent limitations in conducting research in patients with refractory cancer pain; therefore, it is unlikely that higher-quality evidence will emerge in the next few years. Our primary economic evaluation found that IDDSs are more effective and more costly than standard care. The incremental cost-effectiveness ratio of IDDSs compared with standard care is $57,314 per quality-adjusted life-year (QALY) gained. The probability of IDDSs being cost-effective versus standard care is 43.46% at a willingness-to-pay of $50,000 per QALY gained and 72.54% at a willingness-to-pay of $100,000 per QALY gained. Publicly funding IDDSs in Ontario would cost an additional $0.27 million per year, for a total of $1.34 million over the next 5 years. The patients with cancer pain and caregivers with whom we spoke described the debilitating nature of cancer pain and the difficulty of finding effective pain management options. Patients with experience of an IDDS spoke of its effectiveness and its positive impact on their quality of life and mental health. Implementing IDDSs for patients with cancer pain raises several ethical and equity considerations related to the experiences and management of cancer pain, how limitations in evidence may entail uncertainties in clinical and health system decision-making, as well as clinical, geographic, and health system access barriers.

CONCLUSIONS: Intrathecal drug delivery likely reduces pain intensity and decreases the use of systemic opioids in adults with cancer pain who have a life expectancy greater than 6 months. It may also improve health-related quality of life, functional outcomes, and survival, although the evidence for survival is very uncertain. The clinical evidence in children with cancer pain is very uncertain. IDDS implantation is reasonably safe. Intrathecal drug delivery is more effective and more costly than standard care. We estimate that funding IDDSs in Ontario will result in additional costs of $0.27 million per year, for a total of $1.34 million over the next 5 years. Considerations related to funding and implementing IDDSs for patients with cancer pain in Ontario will require explicit and focused attention to considerations of equity and access in the diagnosis and management of cancer pain and in the use, clinical uptake, and delivery of IDDS pain management.

ABSTRACT

Jaktinib, a novel JAK and ACVR1 inhibitor, has exhibited promising results in treating patients with myelofibrosis (MF). ZGJAK002 is a Phase 2 trial aimed to assess the efficacy and safety of jaktinib 100 mg BID (N = 66) and 200 mg QD (N = 52) in JAK inhibitor-naive patients with intermediate- or high-risk MF. We herein present the long-term data with a median follow-up of 30.7 months. At data cutoff, 30.3% of patients in 100 mg BID and 28.8% in 200 mg QD were still continuing their treatment. The 100 mg BID group displayed a numerically higher best spleen response compared with the 200 mg QD group (69.7% vs. 46.2%), with 50.4% from the BID and 51.2% from the QD group maintaining spleen responses over 120 weeks. The 36-month survival rates were 78.2% in BID and 73.6% in QD group. The tolerability of jaktinib remained well, and common grade ≥3 adverse drug reactions included anemia (15.2% vs. 21.2%), thrombocytopenia (15.2% vs. 11.5%), and infectious pneumonia (10.6% vs. 1.9%) in BID and QD groups, respectively. By comparing the two groups, the incidence of adverse events (AEs) were similar, except for drug-related serious AEs (24.2% vs. 9.6%) and AEs leading to treatment discontinuation (15.2% vs. 7.7%), which were higher in BID group. The percentages of AEs resulting in death were comparable, with 6.1% in BID and 5.8% in QD group. These analyses further support the long-term durable efficacy and acceptable safety of jaktinib at 100 mg BID and 200 mg QD doses for treating MF.

ABSTRACT

OBJECTIVE: To determine the frequency of parenteral Acyclovir-induced Acute Kidney Injury (AKI) in patients with viral encephalitis.

STUDY DESIGN: Descriptive study. Place and Duration of the Study: Department of Neurology, Liaquat National Hospital, Karachi, from January to December 2021.

METHODOLOGY: A total of 89 suspected and proven cases of encephalitis receiving IV Acyclovir were collated. All had extensive medical histories and underwent CSF studies with +/- brain imaging. CSF routine and viral PCR were done. Acyclovir-induced AKI was defined as a rise in serum creatinine of >0.3 mg/dl in 48 h or by ≥1.5 times the baseline value, and its severity was staged into 1 (risk), 2 (injury), and 3 (failure) according to the KDIGO guidelines (Kidney Disease: Improving Global Outcomes (KDIGO) Acute Kidney Injury Work Group, 2012). Patients' variables, including age, gender, presenting features, comorbid conditions, and CSF findings, were divided into two groups, i.e. with and without AKI.

RESULTS: This research included 89 patients with a mean age of 48 years. AKI occurred in 34 patients (38.2%). The frequency of AKI with Stage 1 was 24%, Stage 2 was 44%, and Stage 3 was 32%; approximately two-thirds of cases were in Stage 2 and 3 (p >0.05). Five patients (5.6%) from Stage 3, required dialysis.

CONCLUSION: AKI is an important adverse effect of parenteral acyclovir, which necessitates its early identification and timely management. Renal function monitoring is essential for patients on Acyclovir treatment as they are at risk for AKI.

ABSTRACT

OBJECTIVE: To investigate the clinical potential and safety of Moluodan to reverse gastric precancerous lesions.

METHODS: Patients aged 18-70 years diagnosed with moderate-to-severe atrophy and/or moderate-to-severe intestinal metaplasia, with or without low-grade dysplasia, and negative for Helicobacter pylori were recruited in this randomized, double-blind, parallel-controlled trial. The primary outcome was the improvement of global histological diagnosis at 1-year follow-up endoscopy using the operative link for gastritis assessment, the operative link for gastric intestinal metaplasia assessment, and the disappearance rate of dysplasia.

RESULTS: Between November 3, 2017 and January 27, 2021, 166 subjects were randomly assigned to the Moluodan group, 168 to the folic acid group, 84 to the combination group, and 84 to the high-dose Moluodan group. The improvement in global histological diagnosis was achieved in 60 (39.5%) subjects receiving Moluodan, 59 (37.8%) receiving folic acid, 26 (32.1%) receiving the combined drugs, and 36 (47.4%) receiving high-dose Moluodan. Moluodan was non-inferior to folic acid (95% confidence interval: -9.2 to 12.5; P = 0.02). High-dose Moluodan had a trend for better protective efficacy, though there was no statistical significance. The disappearance rate of dysplasia was 82.8% in the Moluodan group, which was superior to folic acid (53.9%; P = 0.006). No drug-related serious adverse events were observed.

CONCLUSIONS: One pack of Moluodan three times daily for 1 year was safe and effective in reversing gastric precancerous lesions, especially dysplasia. Doubling its dose showed a better efficacy trend.

ABSTRACT

BACKGROUND: The androgen receptor is a tumour suppressor in oestrogen receptor-positive breast cancer. The activity and safety of enobosarm, an oral selective androgen receptor modulator, was evaluated in women with oestrogen receptor (ER)-positive, HER2-negative, and androgen receptor (AR)-positive disease.

METHODS: Women who were postmenopausal (aged ≥18 years) with previously treated ER-positive, HER2-negative, locally advanced or metastatic breast cancer with an Eastern Cooperative Oncology Group performance status of 0-2 were enrolled in a randomised, open-label, multicentre, multinational, parallel design, phase 2 trial done at 35 cancer treatment centres in nine countries. Participants were stratified on the setting of immediately preceding endocrine therapy and the presence of bone-only metastasis and randomly assigned (1:1) to 9 mg or 18 mg oral enobosarm daily using an interactive web response system. The primary endpoint was clinical benefit rate at 24 weeks in those with centrally confirmed AR-positive disease (ie, the evaluable population). This trial is registered with ClinicalTrials.gov (NCT02463032).

FINDINGS: Between Sept 10, 2015, and Nov 28, 2017, 136 (79%) of 172 patients deemed eligible were randomly assigned to 9 mg (n=72) or 18 mg (n=64) oral enobosarm daily. Of these 136 patients, 102 (75%) patients formed the evaluable population (9 mg, n=50; 18 mg, n=52). The median age was 60·5 years (IQR 52·3-69·3) in the 9 mg group and 62·5 years (54·0-69·3) in the 18 mg group. The median follow-up was 7·5 months (IQR 2·9-14·1). At 24 weeks, 16 (32%, 95% CI 20-47) of 50 in the 9 mg group and 15 (29%, 17-43) of 52 in the 18 mg group had clinical benefit. Six (8%) of 75 patients who received 9 mg and ten (16%) of 61 patients who received 18 mg had grade 3 or grade 4 drug-related adverse events, most frequently increased hepatic transaminases (three [4%] of 75 in the 9 mg group and two [3%] of 61 in the 18 mg group), hypercalcaemia (two [3%] and two [3%]), and fatigue (one [1%] and two [3%]). Four deaths (one in the 9 mg group and three in the 18 mg group) were deemed unrelated to the study drug.

INTERPRETATION: Enobosarm has anti-tumour activity in patients with ER-positive, HER2-negative advanced breast cancer, showing that AR activation can result in clinical benefit, supporting further clinical investigation of selective AR activation strategies for the treatment of AR-positive, ER-positive, HER2-negative advanced breast cancer.

ABSTRACT

Three-dimensional (3D) bioprinting is one of the most promising methodologies that are currently in development for the replacement of animal experiments. Bioprinting and most alternative technologies rely on animal-derived materials, which compromises the intent of animal welfare and results in the generation of chimeric systems of limited value. The current study therefore presents the first bioprinted liver model that is entirely void of animal-derived constituents. Initially, HuH-7 cells underwent adaptation to a chemically defined medium (CDM). The adapted cells exhibited high survival rates (85-92%) after cryopreservation in chemically defined freezing media, comparable to those preserved in standard medium (86-92%). Xeno-free bioink for 3D bioprinting yielded liver models with high relative cell viability (97-101%), akin to a Matrigel-based liver model (83-102%) after 15 days of culture. The established xeno-free model was used for toxicity testing of a marine biotoxin, okadaic acid (OA). In 2D culture, OA toxicity was virtually identical for cells cultured under standard conditions and in CDM. In the xeno-free bioprinted liver model, 3-fold higher concentrations of OA than in the respective monolayer culture were needed to induce cytotoxicity. In conclusion, this study describes for the first time the development of a xeno-free 3D bioprinted liver model and its applicability for research purposes.

ABSTRACT

Apart from the inequality in vaccination, war zones and areas where communication is disrupted are affected by myths and misconceptions about COVID-19 vaccines, heightening vaccine hesitancy. Local data on adverse events of the vaccines and their mildness can increase confidence and acceptance of the vaccines in the respective population. In areas of conflict and communication blackouts, the perception of the vaccines by health workers is of paramount importance as public health recommendations may not reach the public. Therefore, the scientific evaluation of adverse events following COVID-19 vaccination in such areas is invaluable. This cross-sectional, facility-based study was conducted using a structured, interviewer-administered questionnaire to assess the adverse events experienced by healthcare workers who received the Janssen COVID-19 vaccine. The sample was divided proportionally to the number of vaccinated healthcare workers for the different healthcare professions, and participants were then randomly selected from each profession. Prior to data collection, a pilot test was conducted with 5% of the sample size outside the selected hospital. The study was conducted using a structured questionnaire completed by an interviewer to assess adverse events in 442 healthcare workers who had received the Janssen COVID-19 vaccine between July 11 and 25, 2022. The study period was from August 15 to September 15, 2022. A significant number of healthcare workers [366 (83.3%); 95% CI 79.5%, 86.5%] experienced at least one adverse event. Nearly 90% of participants reported that the adverse events were mild to moderate. Pain at the injection site [307 (69.5%); 95% CI 65.0%, 73.6%] and headache [247 (55.9%); 95% CI 51.2%, 60.4%] were the most common local and systemic adverse events, respectively. Two HCWs experienced anaphylactic reaction. Younger age was significantly associated with the occurrence of adverse events. We deciphered that the adverse events reported by the study participants were not different from the typically occurring vaccine-related adverse reactions, and therefore concluded that post-vaccination reactions in healthcare workers were minor. Although vaccination in Tigray is currently stalled due to the siege, responsible stakeholders should develop a mechanism to track population-wide adverse events once the vaccines start to rollout.

ABSTRACT

OBJECTIVE: Acute pancreatitis (AP) is a process of acute inflammation and cell damage of the pancreas. Gallstones and alcohol abuse are the most common cause for AP. Drug-induced pancreatitis (DIP), accounting for less than 3% of the AP, has become increasingly recognized as an additional and vitally important etiology of acute pancreatitis. Sertraline is an antidepressant of the selective serotonin reuptake inhibitor (SSRI)class that has a range of side effects even when used at the recommended dose. A recognized but rare association in teenagers is acute pancreatitis. The report is of a 15-year-old male teenager with a history of depression who developed acute pancreatitis following self-overdose of his sertraline prescription.

CASE REPORT: A 15-year-old teenager with an overdose of sertraline, which was the only medication he took, presented abdominal pain, nausea, and vomiting. The common causes of alcohol consumption, gallstones, biliary duct obstruction, malignancy, trauma, hypertriglyceridemia, and hypercalcemia were eliminated. The increased level of amylase and parenchymal edema of the pancreas revealed in computed tomography supported the diagnosis of acute pancreatitis. After discontinuation of the drug and conventional acute pancreatitis treatment, he recovered evenly.

CONCLUSION: With the increasing use of antidepressant medications in patients of teenagers, this report is a reminder that clinicians should be aware of the association between SSRIs such as sertraline, particularly in cases of overdose, and the development of acute pancreatitis.

ABSTRACT

Restless leg syndrome (RLS) is a chronic disorder characterized by a compulsive urge to move the legs, accompanied by various subjective symptoms and a distinctive nyctimeral pattern. A negligent entity is drug-induced RLS, which may be challenging to recognize by practitioners due to its rarity. Among various drugs that can induce or exacerbate RLS, metoclopramide is notable; however, the literature primarily describes cases related to its intravenous forms. In this case presentation, a 33-year-old male experienced drug-related gastrointestinal (GI) symptoms after starting semaglutide for weight loss. Semaglutide was discontinued, and oral metoclopramide was administered to manage the GI symptoms. Subsequently, he developed RLS-like symptoms, which resolved within 48 hours of stopping metoclopramide. His family history included chronic RLS. Laboratory tests were normal. The case highlights a potential link between drug administration and transient RLS symptoms. This case suggests that RLS can be a rare, reversible side effect of oral metoclopramide. It emphasizes the need for careful monitoring of RLS symptoms in patients using this drug and highlights the variability of side effects depending on the method of drug administration. The case serves as a reminder of the unpredictable nature of drug reactions and the importance of vigilance in pharmacotherapy.
