Growth differentiation factor-15 predicts all-cause death and major adverse cardiovascular events in patients with coronary heart disease: a prospective cohort study.

The prognostic value of growth differentiation factor-15 (GDF-15) in predicting long-term adverse outcomes in coronary heart disease (CHD) patients remains limited. Our study examines the association between GDF-15 and adverse outcomes over an extended period in CHD patients and firstly assesses the incremental prognostic effect of incorporating GDF-15 into the Framingham risk score (FRS)-based model. This single-center prospective cohort study included 3,321 patients with CHD categorized into 2,479 acute coronary syndrome (ACS) (74.6%) and 842 non-ACS (25.4%) groups. The median age was 61.0 years (range: 53.0-70.0), and 917 (27.6%) were females. Mortality and major adverse cardiovascular events (MACEs) included cardiovascular mortality, myocardial infarction (MI), stroke, and heart failure (HF) (inclusive of HF episodes requiring outpatient treatment and/or hospital admission). Cox regression models assessed the associations between GDF-15 and the incidence of all-cause mortality and MACEs. Patients were stratified into three groups based on GDF-15 levels: the first tertile group (< 1,370 ng/L), the second tertile group (1,370-2,556 ng/L), and the third tertile group (> 2,556 ng/L). The C-index, integrated discrimination improvement (IDI), net reclassification improvement (NRI), and decision curve analysis (DCA) were used to assess incremental value. Over a median 9.4-year follow-up, 759 patients (22.9%) died, and 1,291 (38.9%) experienced MACEs. The multivariate Cox model indicated that GDF-15 was significantly associated with all-cause mortality (per ln unit increase, HR = 1.49, 95% CI: 1.36-1.64) and MACEs (per ln unit increase, HR = 1.29, 95% CI: 1.20-1.38). These associations persisted when GDF-15 was analyzed as an ordinal variable (p for trend < 0.05). Subgroup analysis of ACS and non-ACS for the components of MACEs separately showed a significant association between GDF-15 and both cardiovascular mortality and HF, but no association was observed between GDF-15 and MI /stroke in both ACS and non-ACS patients. The addition of GDF-15 to the FRS-based model enhanced the discrimination for both all-cause mortality (∆ C-index = 0.009, 95% CI: 0.005-0.014; IDI = 0.030, 95% CI: 0.015-0.047; continuous NRI = 0.631, 95% CI: 0.569-0.652) and MACEs (∆ C-index = 0.009, 95% CI: 0.006-0.012; IDI = 0.026, 95% CI: 0.009-0.042; continuous NRI = 0.593, 95% CI: 0.478-0.682). DCA suggested that incorporating GDF-15 into the FRS-based model demonstrated higher net benefits compared to FRS-based models alone (All-cause mortality: FRS-based model: area under the curve of DCA (AUDC) = 0.0903, FRS-based model + GDF-15: AUDC = 0.0908; MACEs: FRS-based model: AUDC = 0.1806, FRS-based model + GDF-15: AUDC = 0.1833). GDF-15 significantly associates with the long-term prognosis of all-cause mortality and MACEs in CHD patients and significantly improves the prognostic accuracy of the FRS-based model for both outcomes.

Incidence and predictors of adverse outcomes in patients with rheumatic mitral stenosis following percutaneous balloon mitral valvuloplasty: a study from a tertiary center in Thailand.

BACKGROUND: Rheumatic mitral stenosis (MS) remains a common and concerning health problem in Asia. Percutaneous balloon mitral valvuloplasty (PBMV) is the standard treatment for patients with symptomatic severe MS and favorable valve morphology. However, studies on the incidence and predictors of adverse cardiac outcomes following PBMV in Asia have been limited. This study aims to evaluate the incidence and predictors of adverse outcomes in patients with rheumatic MS following PBMV. METHODS: A retrospective cohort study was conducted on patients with symptomatic severe MS who underwent successful PBMV between 2002 and 2020 at a tertiary academic institute in Thailand. Patients were followed up to assess adverse outcomes, defined as a composite of cardiac death, heart failure hospitalization, repeat PBMV, or mitral valve surgery. Univariable and multivariable analyses were performed to identify predictors of adverse outcomes. A p-value of < 0.05 was considered statistically significant. RESULTS: A total of 379 patients were included in the study (mean age 43 ± 11 years, 80% female). During a median follow-up of 5.9 years (IQR 1.7-11.7), 74 patients (19.5%) experienced adverse outcomes, with an annualized event rate of 2.7%. Multivariable analysis showed that age (hazard ratio [HR] 1.03, 95% confidence interval [CI] 1.008-1.05, p = 0.006), significant tricuspid regurgitation (HR 2.17, 95% CI 1.33-3.56, p = 0.002), immediate post-PBMV mitral valve area (HR 0.39, 95% CI 0.25-0.64, p = 0.01), and immediate post-PBMV mitral regurgitation (HR 1.91, 95% CI 1.18-3.07, p = 0.008) were independent predictors of adverse outcomes. CONCLUSIONS: In patients with symptomatic severe rheumatic MS, the incidence of adverse outcomes following PBMV was 2.7% per year. Age, significant tricuspid regurgitation, immediate post-PBMV mitral valve area, and immediate post-PBMV mitral regurgitation were identified as independent predictors of these adverse outcomes.

A Pharmacovigilance Study on Clozapine in the Food and Drug Administration Adverse Event Reporting System: A Regional Comparative Analysis.

Objective: This pharmacovigilance study evaluated the profile of clozapine-related adverse events by region using the Food and Drug Administration Adverse Event Reporting System (FAERS). Methods: We categorized each case into five regions (America, Europe/West Asia, Oceania, Asia, and Africa) based on the reporting country information in the FAERS database. The number of clozapine-related adverse events reported in each region was aggregated according to the preferred term (PT) and the Standardized Medical Dictionary for Regulatory Activities (MedDRA) Query (SMQ). Results: A total of 101,872 clozapine-related adverse events were registered in the FAERS database. In America and Europe, leukocyte or neutrophil count abnormalities accounted for half of the top 10 PTs by relative reporting rate. However, Asia had higher relative reporting rates of pyrexia and salivary hypersecretion (13.91% and 10.85%, respectively). Regarding the SMQ, the relative reporting rates of infective pneumonia, convulsions, extrapyramidal syndrome, gastrointestinal obstruction, and hyperglycaemia/new onset diabetes mellitus were higher in Asia than in other regions (5.26%, 9.72%, 12.65%, 5.13%, and 8.26%, respectively), with significant differences even after adjusting for confounding factors using multivariate logistic regression analysis. Conclusion: Spontaneous reports of adverse events associated with clozapine show regional disparities, particularly in Asia, where concentration-dependent adverse events are more frequently reported. However, the spontaneous reporting system has several limitations, requiring further research for validation.

A Case Report of Ketamine-induced Hypoglycemia in Treatment Resistance Depression.

Ketamine therapy can reduce the risk of suicide and depression in the treatment resistant patient. Adverse effects of ketamine infusion include blurred vision, nausea and vomiting, hepatotoxicity, headache, and cystitis. However, the effect of ketamine infusion on blood glucose remains unclear. This report describes several episodes of hypoglycemia in a 36-year-old man with type 1 diabetes mellitus after ketamine infusion for treatment-resistance depression. He has been receiving subcutaneous insulin injection and denied any severe hypoglycemia events in the prior 20 years. He had unsuccessful treatment for depression. His depressive conditions were subsequently improved due to ketamine therapy, however, he had recurrent hypoglycemia episodes. Clinicians should be aware of this potential adverse effect on initiating ketamine infusion with patients who had type 1 diabetes.

A Rare Phenomenon, Recurrent Acute Dystonia after Withdrawal of 'Methylphenidate-immediate Release Form': A Pediatric Case with ADHD.

Drug-induced acute dystonia is usually associated with combination therapies of neuroleptics, but rarely with the withdrawal or rebound effect of various psychotrops. Very sparse reports have described acute dystonia as a methylphenidate withdrawal (rebound effect), particularly in combination modalities. However, there is no case report or research regarding acute dystonia related to the withdrawal of the short-acting methylphenidate-immediate release form (MPH-IR) in the case of monotherapy of MPH-IR or a combination with guanfacine. Herein, a pediatric case of recurrent acute dystonia with two separate phenomena, locating orolingual and oromandibular/lower extremities, is presented as a withdrawal adverse reaction occurring after abrupt discontinuation of MPH-IR when under a combination therapy with guanfacine. Various options such as anticholinergic agents, re-administrating MPH, or turning to monotherapy from combination modalities, can be suggested in treatment, as well as only hydration may also have the benefit of resolving the symptoms, as in the current case. Practitioners should be aware of all possible adverse effects of MPH, even the rebound effect of short-acting forms.

Two Cases of Cytomegalovirus Colitis During the Treatment of Immune Checkpoint Inhibitor-Associated Colitis.

Herein, we outlined two case reports of patients who developed cytomegalovirus colitis following the initiation of corticosteroid therapy for colitis as a result of immune-related adverse events (irAEs). For both patients, endoscopic findings were similar to those observed for patients with irAE colitis but were devoid of the characteristic features associated with cytomegalovirus colitis, including punched-out ulcers. Given the therapeutic disparities between these two conditions, it is imperative to distinguish between these conditions in clinical practice. When addressing exacerbations or refractory manifestations of irAE-associated colitis, clinicians should remain vigilant with regard to the potential for cytomegalovirus infection, even in the absence of punched-out ulcers in the colorectum.

Comparison of Transient and Persistent Adverse Events After COVID-19 Vaccination: A Retrospective Analysis.

OBJECTIVE: Most reported adverse events following COVID-19 vaccination have been transient. However, persistent adverse events may occur with some frequency. This study aimed to analyze patient background characteristics and trends, with a focus on whether adverse events following COVID-19 vaccination were transient or persistent. METHODS: A retrospective study was performed at a single institution in Japan. PATIENTS: The study cohort included 47 patients who presented with symptoms after COVID-19 vaccination between May 2021 and September 2023. The patients were classified into two groups based on the duration of symptoms: transient group, less than four weeks; persistent group, greater than or equal to four weeks. Data on age, sex, body mass index, smoking history, underlying conditions, type of COVID-19 vaccination, number of doses, onset, symptoms, and treatments were collected retrospectively. RESULTS: The median age was 51.0 years and 74.5% were females, with a particularly high proportion of women in their 40s. The use of the bivalent omicron-containing booster vaccine (BA.1) was significantly more common in the persistent group than in the transient group (p = 0.0267). Onset in the transient group was more common after the first vaccination, whereas onset in the persistent group was more common after the second and subsequent vaccinations (p = 0.003). Regarding symptoms, pain was more frequent in the persistent group than in the transient group (60% vs. 13.6%; p = 0.001). CONCLUSIONS: This study investigated the presence of persistent symptoms, especially pain, after COVID-19 vaccination. Persistent symptoms were frequently reported after the second vaccination. It should be noted that the study does not negate the usefulness of COVID-19 vaccines.

Gemcitabine-Induced Thrombotic Microangiopathy in a Patient With Cholangiocarcinoma: An Atypical Case.

Gemcitabine-induced thrombotic microangiopathy (GITMA) is a rare but severe complication seen in cancer patients on gemcitabine therapy. This case report describes a 45-year-old female with metastatic cholangiocarcinoma on gemcitabine-capecitabine who developed acute kidney injury and hypertension without typical hematologic signs of thrombotic microangiopathy (TMA). Despite initial management targeting hypertensive urgency and acute kidney injury, renal function continued to decline and progressed to end-stage renal disease requiring hemodialysis. Laboratory tests revealed TMA features such as elevated lactate dehydrogenase (LDH), decreased haptoglobin, and schistocytes. Renal biopsy confirmed TMA with chronic features. This case highlights the challenge of diagnosing drug-induced TMA without typical hematologic findings.

Adverse Drug Reactions Related with Antibiotic Medicines in Malawi: A Retrospective Analysis of Prevalence and Associated Factors.

Objective: We aimed to assess the occurrence and characteristics of antibiotic-associated adverse drug reactions (ADRs) in Malawi. Methods: We retrospectively reviewed 304 patient records from medical wards in three hospitals in Southern Malawi. A global trigger tool was applied for the detection of suspected ADRs, and we used the Naranjo scale, the World Health Organization classification and the Schumock and Thornton scale for causality, seriousness and preventability assessment respectively. ADRs were also further characterized according to anatomical systems. Statistical analysis was done in STATA 14.1. The Chi-square test was used to determine the association between categorical variables and logistic regression analysis was used to measure the strength of the association between various independent variables and the occurrence of ADRs. Results: Suspected ADRs were detected in 24% (73/304) of patients, of which 1.4% were definite, 15.1% were probable and 83.6% were possible ADRs. Most of the sADRs were gastrointestinal events (42.5%), followed by: musculoskeletal (26.3%); cardiovascular (16.3%); central nervous system (13.8%; and urinary events (1.3%). About 27% of the sADRs were serious events such as convulsions. The geriatric age group (≥65 years) was more likely to experience sADRs as compared to the younger age group, with an adjusted odds ratio (aOR) of 4.53, 95% CI (2.21-9.28), P<0.001. Patients taking more than one antibiotic medicine had a higher risk of developing sADRs as compared to patients who were administered one type of antibiotic medicine, aOR 2.14, 95% CI (1.18-3.90), p < 0.012. A long hospital stay of >3days was associated with a higher risk of sADRs with aOR of 5.11, 95% CI (2.47-10.55), p < 0.001 than those who stayed ≤ 3 days in the hospital. Conclusion: We found a higher prevalence of serious sADRs associated with antibiotic medicines than reported elsewhere. This may, among others, contribute to high patient mortality, poor treatment adherence, antibiotic resistance and increased cost of care.

What is already known and why we did the study? Most health care workers and patients are less likely to voluntarily report suspected adverse drug reactions in low- and middle-income countries such as Malawi.Studies have revealed a high usage of antibiotic medicines in Malawi, but there is limited data on the associated adverse drug reactions. What did we do? We assessed the occurrence and characteristics of ADRs associated with antibiotics. What are the new findings? We found a higher prevalence (24%) of adverse drug reactions associated with antibiotic therapy than reported elsewhere using the global trigger tool.About 27.4% of the events were serious ADRs such as convulsions, arrhythmia and hypotension.We observed a higher rate of convulsions which could be a potential safety signal. What do the new findings imply? The high prevalence of serious ADRs leads to complicated treatment strategies and contribute to patient mortality, poor treatment adherence and antibiotic resistance.ADR risk factors need to be considered when prescribing and monitoring patients on antibiotic therapy.

Comparing the adverse effects of ketamine and esketamine between genders using FAERS data.

Background: Ketamine was developed as an anesthetic. Esketamine is the isolated S-enantiomer of racemic ketamine. They provide new avenues for the treatment of depression, especially treatment-resistant depression. Considering differences in the pharmacokinetics and hormonal status of ketamine in patients of different genders, sex-based differences in esketamine adverse drug events (ADE) may also be observed. This study presents data mining and safety analysis of adverse events of ketamine and esketamine between genders, promoting the individualization of clinical practice. Methods: Adverse drug reactions to ketamine and esketamine reported between the first quarter of 2004 and the second quarter of 2023 in the U.S. Food and Drug Administration on Adverse Event Reporting System (FAERS) were extracted. Thereafter, the reporting odds ratio (ROR) with 95% confidence interval (CI) was calculated. Results: A total of 2907 female reports and 1634 male reports on esketamine were included in the analysis. ROR mining showed that completed suicide, decreased therapeutic product effects, urinary retention, and hypertension were common in men. Additionally, 552 female and 653 male ketamine reports were recorded. ROR mining revealed that toxicity to various agents, bradycardia, cystitis and agitation, were more likely to occur in men, whereas women were more likely to develop suicidal ideation, increased transaminase levels, sclerosing cholangitis, and sterile pyuria. Conclusion: The adverse events of esketamine and ketamine differ across genders, which should be considered in clinical practice to provide individualized treatment.

Efficacy and safety of over-the-scope-clips in the therapy of acute nonvariceal upper gastrointestinal bleeding: Meta-analysis.

BACKGROUND: Acute nonvariceal upper gastrointestinal bleeding (ANVUGIB) is a frequent life-threatening acute condition in gastroenterology associated with high morbidity and mortality. Over-the-scope-clip (OTSC) is a new endoscopic hemostasis technique, which is being used in ANVUGIB and is more effective. AIM: To summarize and analyze the effects of the OTSC in prevention of recurrent bleeding, clinical success rate, procedure time, hospital stay, and adverse events in the treatment of ANVUGIB, to evaluate whether OTSC can replace standard endoscopic therapy as a new generation of treatment for ANVUGIB. METHODS: The literature related to OTSC and standard therapy for ANVUGIB published before January 2023 was searched in PubMed, Web of Science, EMBASE, Cochrane, Google, and CNKI databases. Changes in recurrent bleeding (7 or 30 days), clinical results (clinical success rate, conversion rate to surgery, mortality), therapy time (procedure time, hospital stay), and adverse events in the OTSC intervention group were summarized and analyzed, and the MD or OR of 95%CI is calculated by Review Manager 5.3. RESULTS: This meta-analysis involved 11 studies with 1266 patients. Total risk of bias was moderate-to-high. For patients in the OTSC group, 7- and 30-days recurrent bleeding rates, as well as procedure time, hospital stay, and intensive care unit stay, were greatly inhibited. OTSC could significantly improve the clinical success rate of ANVUGIB. OTSC therapy did not cause serious adverse and was effective in reducing patient mortality. CONCLUSION: OTSC may provide more rapid and sustained hemostasis, and thus, promote recovery and reduce mortality in patients with ANVUGIB. In addition, the safety of OTSC is assured.

Adverse childhood experiences and risky behaviors in Oman: A cross-sectional study.

Objective: Adverse childhood experiences (ACEs), which refer to potentially traumatic events occurring during childhood, have been consistently linked to detrimental effects on high-risk behaviors through various studies. Nonetheless, such an association has rarely been examined in the context of Arab culture. This study aimed to investigate the association between ACE levels and high-risk behaviors (e.g., smoking, alcohol consumption, drug use, high-risk sexual behavior, and physical inactivity) among Omani adults. Methods: This was a cross-sectional study with convenience sampling. The participants were recruited from a university-affiliated medical facility in Oman. Data were collected in 2022. They were asked to complete the Adverse Childhood Experience International Questionnaire (ACE-IQ). Results: The study included 1648 Omani adults. Analyses revealed that the adjusted odds ratios (ORs) for engaging in some of the identified high-risk behaviors increased as the level of ACEs increased. Specifically, individuals with an ACE level of 4 exhibited higher odds of smoking (OR: 2.6), alcohol consumption (OR: 2.9), and risky sexual behavior (OR: 32) than those without ACEs. Conclusion: The findings of this study underscore a notable association between ACEs and high-risk behaviors among Omani adults. Consequently, there is a pressing need for intensified efforts to prevent ACEs when possible and to alleviate their adverse effects, emphasizing the importance of public health initiatives and interventions in Oman.

Characterizing immune checkpoint inhibitor-related cutaneous adverse reactions: A comprehensive analysis of FDA adverse event reporting system (FAERS) database.

Background: The increasing adoption of immune checkpoint inhibitors (ICIs) in clinical settings highlights their efficacy in treating diverse conditions, while also emphasizing the potential for common cutaneous adverse reactions to arise. The aim of this study is to investigate a multitude of impacting factors and determinants among patients presenting with ICI-associated cutaneous adverse reactions. Methods: We conducted a comprehensive analysis of ICI-associated cutaneous adverse reactions using data from the FAERS. Our study spans from January 1, 2015, to March 31, 2023, focusing on ICIs, including anti-PD-1, anti-PD-L1, and anti-CTLA-4 agents. Findings: Among the 334,293 reported irAR, 17,431 were identified as cutaneous adverse reactions (ARs). Predominant cutaneous ARs included rash (21.01 %), pruritus (11.22 %), and pemphigoid (3.90 %). Stevens-Johnson syndrome emerged as the most reported severe cutaneous adverse reaction (SCAR) (2.08 %). Anti-CTLA-4 agents exhibited higher cutaneous toxicity compared to anti-PD-1 and anti-PD-L1 agents. Anti-PD-1 agents demonstrated an elevated mortality rate. The combined use of ICIs with chemotherapy amplified the risk of SCAR and mortality. Targeted therapy was a risk factor for cutaneous ARs but was associated with reduced mortality. The median onset day for cutaneous toxicity was 21 days, while for SCAR, it was 23 days. Weight and age were identified as predictors of SCAR, cutaneous toxicity, and mortality. Skin cancer increased skin toxicity, while lung cancer heightened SCAR formation. The number of administered ICIs positively correlated with SCAR, skin toxicity, and mortality. Interpretation: This study highlights the significance of early identification and effective management of cutaneous toxicities, along with personalized follow-up care, as essential strategies for minimizing risks and preventing treatment disruptions.

Cardiac arrest and cardiogenic shock complicating ST-segment elevation myocardial infarction in China: A retrospective multicenter study.

Background: Data on the effect of cardiac arrest (CA), cardiogenic shock (CS), and their combination on the prognosis of Chinese patients with ST-segment elevation myocardial infarction (STEMI) are limited. The present study sought to evaluate the clinical outcomes of STEMI complicated by CA and CS, and to identify the risk factors for CA or CS. Methods: This study included 7468 consecutive patients with STEMI in China. The patients were divided into 4 groups (CA + CS, CA only, CS only, and No CA or CS). The endpoints were 30-day all-cause death and major adverse cardiovascular events. A Cox proportional hazards regression analysis was performed. Results: CA, CS, and their combination were noted in 332 (4.4 %), 377 (5.0 %), and 117 (1.6 %) among all patients. During the 30-day follow-up, 817 (10.9 %) all-cause deaths and 964 (12.9 %) major adverse cardiovascular events occurred, and the incidence of all-cause mortality (3.6 %, 62.3 %, 74.1 %, 83.3 %) and major adverse cardiovascular events (5.4 %, 67.1 %, 75.0 %, and 87.2 %) significantly increased in the No CA or CS, CS only, CA only, and CA + CS groups, respectively. In the multivariate Cox regression models, compared with the No CA or CS group, the CA + CS, CA, and CS-only groups were associated with an increased risk of all-cause death and major adverse cardiovascular events. Patients with CA + CS had the highest risk of all-cause death (hazard ratio [HR], 25.259 [95 % confidence interval (CI) 19.221-33.195]) and major adverse cardiovascular events (HR 19.098, 95%CI 14.797-24.648). Conclusions: CA, CS, and their combination were observed in approximately 11 % of Chinese patients with STEMI, and were associated with increased risk for 30-day mortality and major adverse cardiovascular events in Chinese patients with STEMI.

Predicting Intraindividual Change in Satisfaction with Life During COVID-19: A Prospective Study of Swiss Older Adults with Differing Levels of Childhood Adversity.

Objectives This study examined intraindividual change in satisfaction with life (SWL) in Swiss older adults before, during, and after COVID-19. It assessed whether predictors of adaptation influenced SWL stability, and whether this differed depending on adverse childhood experiences (ACE). Methods SWL was assessed eight times over a 21-month period. ACE, emotion regulation, meaning in life, and subjective socio-economic status (SES) were assessed as predictors. Data were analyzed using growth curve modeling. Results The sample consisted of two groups: A risk group (RG: n = 111, M age = 69.4 years) comprised of individuals with a high risk of having been exposed to ACE, and a (low-risk) control group (CG: n = 120, M age = 70.3 years). Intraindividual change in SWL was predicted by (presence of) meaning in life only in the RG, and by subjective SES only in the CG. Conclusion Results identified predictors of stable SWL trajectories and the potential for positive psychological functioning into later life, despite past and current prolonged adversity.

Exploring predictive molecules of acute adverse events in response to volumetric­modulated arc therapy for prostate cancer using urinary metabolites.

Volumetric-modulated arc therapy (VMAT) is a radiotherapy technique used to treat patients with localized prostate cancer, which is frequently associated with acute adverse events (AEs) that can affect subsequent treatment. Notably, the radiation dose of VMAT can be tailored to each patient. In the present study, a retrospective analysis was performed to predict acute AEs in response to a therapeutic high radiation dose rate based on urinary metabolomic molecules, which are easily collected as noninvasive biosamples. Urine samples from 11 patients with prostate cancer who were treated with VMAT (76 Gy/38 fractions) were collected. The study found that seven patients (~64%) exhibited genitourinary toxicity (Grade 1) and four patients had no AEs. A total of 630 urinary metabolites were then analyzed using a mass spectrometer (QTRAP6500+; AB SCIEX), and 234 relevant molecules for biological and clinical applications were extracted from the absolute quantified metabolite values using the MetaboINDICATOR tool. In the Grade 1 acute AE group, there was a significant negative correlation (rs=-0.297, P<0.05) between the number of VMAT fractions and total phospholipase A2 activity in the urine. Additionally, patients with Grade 1 AEs exhibited a decrease in PC aa C40:1, a phospholipid. These findings suggested that specific lipids found in urinary metabolites may serve as predictive biomarkers for acute AEs in response to external radiotherapy.

A rare adverse effect in inebilizumab therapy for neuromyelitis optica spectrum disorder: a case report.

Inebilizumab is one of the monoclonal antibodies approved as maintenance therapy for aquaporin-4 immunoglobulin G-seropositive neuromyelitis optica spectrum disorder (NMOSD). It is a humanized monoclonal antibody targeting cluster of differentiation 19 (CD19). Common adverse reactions include urinary tract infections, nasopharyngitis, arthralgia, infusion reactions, headaches and a decrease in immunoglobulin levels. Here, we present a case of an NMOSD patient who experienced transient hyperCKaemia after the use of inebilizumab. The adverse reactions of this very rare monoclonal antibody drug improved after discontinuation.

Stevens-Johnson syndrome and toxic epidermal necrolysis associated with immune checkpoint inhibitors: a systematic review.

Introduction: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare yet life-threatening adverse events associated with immune checkpoint inhibitors (ICIs). This systematic review synthesizes the current literature to elucidate the clinical characteristics and outcomes of patients with ICI-related SJS/TEN. Methods: We conducted a thorough search across databases including Embase, Web of Science, Cochrane, MEDLINE, Scopus, and PubMed. Selection criteria focused on reports of SJS/TEN among cancer patients treated with ICIs, analyzing clinical manifestations, therapeutic interventions, and outcomes. Results: Our analysis included 47 articles involving 50 patients with ICI-related SJS/TEN. The cohort had a mean age of 63 years, with a slight male predominance (54%). Most patients had melanoma or non-small cell lung cancer. SJS/TEN typically occurred early, with a median onset of 23 days post-ICI initiation. Treatment primarily involved systemic corticosteroids and intravenous immunoglobulins. The overall mortality rate was 20%, higher for TEN at 32%, with infections and tumor progression as leading causes. Median time from onset to death was 28 days. Survivors experienced a median re-epithelization time of 30 days, positively correlated with the extent of epidermal detachment (rs = 0.639, p = 0.009). Deceased patients exhibited a significantly higher proportion of TEN (90% vs. 48%, p = 0.029) and a larger epidermal detachment area (90% vs. 30% of the body surface area [BSA], p = 0.005) compared to survivors. The combination therapy group showed a higher proportion of TEN compared to corticosteroid monotherapy or non-corticosteroid therapy groups (72% vs. 29% and 50%, p = 0.01), with no significant differences in mortality or re-epithelization time. Dual ICI therapy resulted in a higher TEN rate than single therapy (100% vs. 50%, p = 0.028). Among single ICI therapies, the sintilimab-treated group trended towards a higher TEN rate (75% vs. 40-50%, p = 0.417), a larger detachment area (90% vs. 30-48% of BSA, p = 0.172), and a longer re-epithelization time (44 vs. 14-28 days, p = 0.036) compared to other ICI groups, while mortality rates remained similar. Conclusion: ICI-related SJS/TEN substantially impacts patient outcomes. Prospective clinical trials are critically needed to further clarify the pathogenesis and optimize therapeutic regimens.
