Herpes zoster in patients with glioma treated with temozolomide

BackgroundThe risk of herpes zoster in patients treated with temozolomide is poorly defined in the literature. We aimed to evaluate the incidence of and risk factors for herpes zoster in individuals receiving temozolomide for glioma. MethodsA retrospective observational study was conducted on a series of patients treated with temozolomide for glioma at a single centre between 1 October 2018 and 30 September 2023. Results131 patients were treated with temozolomide for glioma with a median age of 55 years. 4 out of 131 patients (3.1 %) developed herpes zoster during temozolomide treatment. All cases of herpes zoster occurred in patients who had lymphocyte nadirs of less than 0.7 x 109/L and were receiving corticosteroids concomitantly. The estimated herpes zoster incidence rates were 45.44 per 1000 person-years (95 % confidence interval (CI) 12.38–116.34 per 1000 person-years) in the overall study population and 224.97 per 1000 person-years (95 % CI 61.30–576.02 per 1000 person-years) in subjects who were treated with corticosteroids and had a lymphocyte nadir of less than 1.0 x 109/L. ConclusionUse of temozolomide, particularly in conjunction with lymphopaenia or corticosteroid use, poses a risk of herpes zoster. Further research into the benefits of prophylactic antiviral measures in this population is recommended.

Multidisciplinary Educational Program to Standardize Education and Management of Immune-related Adverse Events: Review and Outcomes of a Single-institution Initiative.

The use of immune checkpoint inhibitors (ICIs) as anticancer therapy across a variety of malignancies has led to durable efficacy in a subset of patients. However, associated side effects denoted immune-related adverse events (irAEs) have emerged and can result in substantial morbidity and mortality. Particularly early in the experience of using these agents, a lack of standardized education regarding irAEs among patients and clinical providers may have contributed to poor outcomes. Optimal management of these emerging toxicities depends on a coordinated institutional approach. We hypothesized that centralized educational programs and electronic health record (EHR)-based interventions, targeted both toward ICI-treated patients as well as patient-interfacing providers, would improve patient outcomes. We created a multidisciplinary team of clinicians and associated staff to direct a coordinated approach to the education and management of patients receiving ICIs across our institution. A 3-tiered approach was designed: patient-centered, internally centered, and externally centered. Multimedia educational products were produced for patients to improve knowledge and awareness of ICIs and associated irAEs. An EHR-based banner was deployed to improve identification of patients receiving ICIs across disciplines. Tailored educational seminars were provided to clinicians who interact with ICI-treated patients at all levels. Educational seminars were also offered to local physicians and institutions. We assessed patient uptake of educational products and surrogate patient outcomes to measure the potential impact of our interventions. Fox Chase Cancer Center (FCCC)-specific ICI identification cards were created and distributed to patients. By the end of the investigational period, 98.6% of ICI-treated patients reported receiving a card. An ICI-focused on-line portal was created accessible only to ICI-treated patients, with 9.4% of these patients accessing the portal in the first 6 months without marketing promotion. Deidentified surrogate clinical endpoints of corticosteroid use, direct referral unit (DRU) visits, and hospital admissions all improved during the study period. Institutionally directed educational initiatives are feasible at a free-standing academic cancer center and may lead to improved outcomes in patients developing irAEs from ICIs. More granular patient-specific data and studies at other types of institutions are necessary to determine the applicability of similar approaches on a broader scale.

Quero usar corticosteroides numa articulação. O que considerar?

The use of intra-articular corticosteroids is frequent in joint pathology, particularly in osteoarthritis. Although it offers a temporary relief of pain, inflammation and function, their long-term safety and efficacy remain controversial. Particulate corticosteroids have a sustained release, while non-particulate corticosteroids have a faster onset of action but a shorter duration of effect. This narrative review highlights the importance of informed IAC selection based on pharmacokinetics, potential benefits, and cartilage risks.

Actualización de la tricodinia, un reto para los dermatólogos

Trichodynia is the sensation of pain in the scalp, which, in most cases, is associated with certain types of alopecia. Despite being a term coined by Rebora back in 1996 to described patients with diffuse alopecia consistent with telogen effluvium, this symptom has currently been reported in other entities. Androgenic alopecia, scarring alopecia, alopecia areata, trichotillomania, and chemotherapy-induced alopecia are common causes of trichodynia. Similarly, its association with psychiatric comorbidities, including depression, anxiety, obsessive-compulsive disorder and somatoform disorders has been reported with a higher prevalence among women. Although its pathogenesis is still to be elucidate, some factors involved are substanceP, psychiatric comorbidities and perifollicular inflammation. Clinically it exhibits pain or discomfort of the scalp, almost always in association with hair los. The sensation of pain can occur throughout the scalp or locally in some specific areas. Diagnosis is clinical and one of exclusion. Regarding treatment, there are no specific therapies for trichodynia. However, the use of botulinum toxinA, antidepressants, neuromodulators, propranolol, topical corticosteroids, oral corticosteroids and topical cannabinoids are therapeutic alternatives that should be taken into consideration. Since treatment of trichodynia is still therapeutically challenging for dermatologists more prospective studies are needed to evaluate new therapies.

Dupilumab Versus Mepolizumab for Chronic Rhinosinusitis With Nasal Polyposis: An Indirect Treatment Comparison

BackgroundDupilumab and mepolizumab have shown efficacy and safety in treating chronic rhinosinusitis with nasal polyps (CRSwNP). ObjectiveWithout available results from head-to-head randomized control trials (RCTs) comparing dupilumab with other biologics, we conducted an indirect treatment comparison (ITC) with mepolizumab. MethodsA systematic literature review identified RCTs of biologics in CRSwNP. A Bucher ITC was performed, including nasal polyp score (NPS; range 0–8), nasal congestion (NC; 0–3), loss of smell (LOS; 0–3), University of Pennsylvania Smell Identification Test (UPSIT; 0–40), visual analog score (VAS; 0–10), Sino-Nasal Outcome Test (SNOT-22; 0–110), systemic corticosteroids (SCS) use or surgery for nasal polyps (NPs), and binary responder analyses for NPS and SNOT-22 improvement by ≥1/≥2 and ≥8.9, respectively. Matching-adjusted indirect comparisons (MAIC) were conducted as supporting analyses. ResultsSINUS-24/-52 (SYNAPSE-like subpopulation only) and SYNAPSE were identified for ITC. At 24 weeks, change from baseline in NPS and proportion of patients with a binary responder outcome of NPS improvement ≥1 were significantly (P<0.05) greater in patients receiving dupilumab versus mepolizumab. At 52 weeks, improvements in NPS, NC, LOS, UPSIT, and VAS were significantly (P<0.05) greater for dupilumab versus mepolizumab. Proportion of patients achieving binary responder outcomes of NPS and SNOT-22 improvement by ≥1/≥2 and ≥8.9, respectively, was significantly (P<0.05) higher, while SCS use was significantly (P<0.05) reduced, for dupilumab versus mepolizumab. Surgery rate was numerically reduced with dupilumab versus mepolizumab. The MAIC analyses confirmed these results. ConclusionsDupilumab was associated with greater improvements in CRSwNP-related outcomes versus mepolizumab.

Severe Fatigue in Uncontrolled Asthma: Contributing Factors and Impact of Rehabilitation

BackgroundFatigue is a major concern for patients with severe asthma. ObjectiveThis observational study aims to assess fatigue severity and associated factors, to explore the effect of pulmonary rehabilitation on fatigue, and to investigate which factors predict persistent severe fatigue. MethodsPatients with severe, uncontrolled asthma referred for alpine altitude climate treatment (AACT) between 2007 and 2018 were systematically assessed pre- and post-rehabilitation regarding clinical, inflammatory, functional, and psychological characteristics. Fatigue severity was assessed by Checklist Individual Strength (CIS-Fatigue). Multivariable regression analyses were used to identify factors associated with fatigue severity and persistence. Results420 patients were assessed of whom 91% reported severe fatigue (CIS-Fatigue ≥36). Stepwise multiple regression explained 35% of variance in initial fatigue severity. Significant contributing factors were higher ACQ (36%), sleeping problems (21%), female sex (19%), reflux (12%) and lower FENO (12%). AACT led to significant improvements in CIS-Fatigue (median(IQR) 50(11) to 27(21)) (p<0.001), ACQ (3.0(1.3) to 1.2(1.3)) (p<0.001), and other asthma outcomes. However, 27% of patients reported persistent severe fatigue, correlating with less improvement in asthma outcomes. Daily oral corticosteroid (OCS) use OR(95%CI) 2.4(1.4-4.1), sleeping problems OR(95%CI) 2.7(1.6-4.5), initial very severe fatigue OR(95%CI) 3.1(1.6-6.3), and older age OR(95%CI) 1.02 (1.0-1.04) were independent predictors of persistent severe fatigue. ConclusionSevere fatigue is highly prevalent in patients with severe, uncontrolled asthma. Alpine altitude climate treatment results in recovered fatigue and improved asthma control in most patients. Predicting factors of persistent fatigue suggest exploring the effect of targeted treatment strategies beyond the asthma domain.

Multiple Anterior Chamber Paracenteses May Be Needed to Identify Cytomegalovirus Anterior Uveitis

PURPOSETo demonstrate cases of anterior uveitis requiring more than one anterior chamber paracenesis to elucidate CMV as the causative etiology. DESIGNRetrospective chart review. METHODSPatients were seen at the Francis I. Proctor Foundation at the University of California, San Francisco between 2013 to 2024. Patients who required more than one anterior chamber paracentesis to detect CMV as the etiologic agent of their anterior uveitis were included. Number of anterior chamber paracenteses required to detect CMV, demographic and clinical features, viral load at time of positive anterior chamber paracentesis and association between topical corticosteroid use and viral load at time of positive anterior chamber paracentesis. RESULTSFourteen patients required a median of 2 (range 2-4) anterior chamber paracenteses to detect CMV. Mean age was 48.2 years, and 57.1% were male. Most patients (64.3%) were born in East and Southeast Asia. All affected eyes featured ocular hypertension. Five patients (35.7%) were initially treated with systemic immunosuppression before CMV was detected. Increasing frequency of topical corticosteroid use was significantly associated with higher CMV viral loads (p<0.001). Five patients (35.7%) required glaucoma surgery. In 13 patients with available data, uveitis was present for an average of 2776 days (range 23-7889 days) prior to CMV detection. Once diagnosed, most patients were treated with oral valganciclovir, with one patient transitioning to letermovir due to side effects. CONCLUSIONSCMV anterior uveitis may be more prevalent than previously recognized and often requires multiple anterior chamber paracenteses for diagnosis. Reliance on a signle negative test may lead to misdiagnosis and inappropriate treatment. Clinicians should maintain a high index of suspicion for CMV in cases of recurrent anterior uveitis, particularly in patients of East and Southeast Asian descent. This study highlights the importance of repeated testing and appropriate antiviral treatment to prevent complications such as glaucoma.

Characterization of flare-ups and impact of garetosmab in adults with fibrodysplasia ossificans progressiva: a post hoc analysis of the randomized, double-blind, placebo-controlled LUMINA-1 trial.

Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare disorder, characterized by progressive heterotopic ossification (HO) and painful soft-tissue inflammatory flare-ups. This was a post hoc analysis from a phase 2 (NCT03188666) trial in which adults with FOP received intravenous anti-activin A antibody garetosmab 10mg/kg or placebo every 4wk over 28wk (Period 1), followed by a 28-wk open-label treatment and extension (Periods 2 and 3). Here we describe flare-ups, their relationship to new HO lesions, and the impact of garetosmab on flare-ups. Volume of new HO lesions was measured by CT. Patient-reported flare-ups were defined by any 2 of the following: new onset of pain, swelling, joint stiffness, decrease in movement, or perceived presence of HO. Flare-ups were experienced by 71% (17/24) of placebo-treated patients, 59% (10/17) of whom developed a new HO lesion irrespective of flare-up location; 24% of flare-ups location-matched new HO lesions. Twenty-nine new HO lesions occurred in the placebo cohort by week 28, of which 12 (41%) occurred in the same location as new or ongoing flare-ups. A higher volume of newly formed heterotopic bone (week 28) occurred in placebo-treated patients who had experienced a prior flare-up vs those without (median [Q1:Q3] of 16.6 [12.0:31.1] vs 3.2cm3). Garetosmab was previously shown to decrease patient-reported flare-up frequency in Period 1; here, garetosmab reduced the median (Q1:Q3) duration of patient-reported flares (15.0 [6.0:82.0] vs 48.0 [15.0:1.00] d) and the severity of flare-ups vs placebo. Frequency of corticosteroid use was numerically reduced in those treated with garetosmab (40.0%) vs placebo (58.3%). In this analysis, 71% of placebo-treated adults with FOP experienced flare-ups over 28wk, which were associated with an increased volume of newly formed heterotopic bone. Garetosmab reduced the severity and duration of flare-ups, with effects sustained during the entire trial.

Real-World Effectiveness of Mepolizumab in Severe Asthma: Results from the Multi-country, Self-controlled Nucala Effectiveness Study (NEST).

The Nucala Effectiveness Study (NEST) assessed the effectiveness of mepolizumab in patients with severe asthma (SA) in countries previously underrepresented in real-world studies. A multi-country, bi-directional, self-controlled, observational cohort study conducted in Colombia, Chile, India, Türkiye, Saudi Arabia, United Arab Emirates, Kuwait, Oman, and Qatar. Historical and/or prospective data from patients with SA were assessed 12months pre- and post-mepolizumab initiation. incident rate ratio (IRR) of clinically significant exacerbations (CSEs). Key secondary endpoints: healthcare resource utilisation (HCRU), oral corticosteroid (OCS) use, lung function and symptom control (Asthma Control Test [ACT] scores). Overall, 525 patients with SA burden pre-initiation (geometric mean blood eosinophil count [BEC] 490.7 cells/µl; 31.4% prior biologic use; 37.3% obese) received at least one dose of mepolizumab 100mg subcutaneously. Post-initiation, a significant reduction in CSEs was observed (76% [p < 0.001]; IRR [95% confidence interval] 0.24 [0.19-0.30]); 72.0% of patients had no CSEs. Mepolizumab treatment led to a reduction in OCS use (52.8% pre-initiation vs. 16.6% post-initiation) and a mean (standard deviation [SD]) change in OCS dose of -18.1 (20.7) mg post-initiation; 36.1% of patients became OCS-free. Fewer patients were hospitalised post-initiation (22.5% pre-initiation vs. 6.9% post-initiation). Improvements in mean (SD) forced expiratory volume in 1s (62.8 [20.2]% pre-initiation vs. 73.0 [22.7]% post-initiation) and ACT scores (15.0% pre-initiation vs. 64.5% of patients post-initiation with well-controlled asthma) were observed. Proportion of patients with BEC ≥ 500 cells/µl decreased from 84.4% pre-initiation to 18.1% post-initiation. Mepolizumab was effective in reducing the burden of SA by significantly reducing CSEs, reducing OCS use and HCRU, and improving lung function and asthma control, which could translate to improvements in health-related quality of life in patients with SA and high OCS dependency in the countries studied. A graphical abstract is available with this article.

Prevalence of HLA-B27, clinical characteristics and treatment outcomes in children with enthesitis-related arthritis

BackgroundEnthesitis-related arthritis (ERA) is a subtype of juvenile idiopathic arthritis with high disease burden. The objectives of this study were to explore the prevalence of HLA-B27, clinical characteristics, and treatment outcomes in children with ERA and compare the differences between HLA-B27 positive and negative patients.MethodsA retrospective cohort study at a pediatric rheumatology clinic in a tertiary referral hospital in Bangkok, Thailand, including ERA patients with at least 6 months of follow-up (July 2011-April 2022) was performed. Data were collected from medical records from diagnosis to recent follow-up, assessing disease activity and treatment outcomes, with an analysis comparing HLA-B27 positive and negative patients. Descriptive statistics were used for data analysis.ResultsThere were 59 ERA patients with mean age ± SD at diagnosis 11.2 ± 2.5 years, 53 males (89.8%), and positive HLA-B27 in 38 patients (64.4%). The HLA-B27 positive group had significantly higher levels of inflammatory markers at initial diagnosis (p = 0.001), lower baseline hemoglobin (p = 0.001) and hematocrit (p = 0.002), higher disease activity assessed by the Juvenile Spondyloarthritis Disease Activity score at 6 and 12 months of follow-up (p = 0.028 and 0.040, respectively), increased utilization of bridging systemic corticosteroids (60.5% vs. 14.3%, p = 0.001) and anti-TNF (39.5% vs. 9.5%, p = 0.018), and longer duration of methotrexate (median[IQR] 1.7[1.1–3.1] vs. 1.3[0.6–1.9] years, p = 0.040). The HLA-B27 negative group had more prevalent hip arthritis than the positive group at initial diagnosis (66.7% vs. 28.9%, p = 0.005) and during the course of the disease (71.4% vs. 36.8%, p = 0.011).ConclusionMost of the ERA patients tested positive for HLA-B27. Throughout the follow-up period, these patients demonstrated greater disease activity, greater use of corticosteroids and anti-TNF, and longer duration of methotrexate to control the disease.

Machine learning prediction and explanatory models of serious infections in patients with rheumatoid arthritis treated with tofacitinib

BackgroundPatients with rheumatoid arthritis (RA) have an increased risk of developing serious infections (SIs) vs. individuals without RA; efforts to predict SIs in this patient group are ongoing. We assessed the ability of different machine learning modeling approaches to predict SIs using baseline data from the tofacitinib RA clinical trials program.MethodsThis analysis included data from 19 clinical trials (phase 2, n = 10; phase 3, n = 6; phase 3b/4, n = 3). Patients with RA receiving tofacitinib 5 or 10 mg twice daily (BID) were included in the analysis; patients receiving tofacitinib 11 mg once daily were considered as tofacitinib 5 mg BID. All available patient-level baseline variables were extracted. Statistical and machine learning methods (logistic regression, support vector machines with linear kernel, random forest, extreme gradient boosting trees, and boosted trees) were implemented to assess the association of baseline variables with SI (logistic regression only), and to predict SI using selected baseline variables using 5-fold cross-validation. Missing values were handled individually per prediction model.ResultsA total of 8404 patients with RA treated with tofacitinib were eligible for inclusion (15,310 patient-years of total follow-up) of which 473 patients reported SIs. Amongst other baseline factors, age, previous infection, and corticosteroid use were significantly associated with SI. When applying prediction modeling for SI across data from all studies, the area under the receiver operating characteristic (AUROC) curve ranged from 0.656 to 0.739. AUROC values ranged from 0.599 to 0.730 in data from phase 3 and 3b/4 studies, and from 0.563 to 0.643 in data from ORAL Surveillance only.ConclusionsBaseline factors associated with SIs in the tofacitinib RA clinical trial program were similar to established SI risk factors associated with advanced treatments for RA. Furthermore, while model performance in predicting SI was similar to other published models, this did not meet the threshold for accurate prediction (AUROC > 0.85). Thus, predicting the occurrence of SIs at baseline remains challenging and may be complicated by the changing disease course of RA over time. Inclusion of other patient-associated and healthcare delivery-related factors and harmonization of the duration of studies included in the models may be required to improve prediction.Trial registrationClinicalTrials.gov: NCT00147498; NCT00413660; NCT00550446; NCT00603512; NCT00687193; NCT01164579; NCT00976599; NCT01059864; NCT01359150; NCT02147587; NCT00960440; NCT00847613; NCT00814307; NCT00856544; NCT00853385; NCT01039688; NCT02187055; NCT02831855; NCT02092467.

Analysis of immune checkpoint inhibitors for advanced non-small cell lung cancer in patients receiving antacids

BackgroundProton pump inhibitors (PPIs) are reported to decrease the efficacy of immune checkpoint inhibitors (ICIs), but there are few reports on the association between ICI efficacy and antacids other than PPIs, and simultaneous examination of the effects of antacids, corticosteroids, and non-steroidal anti-inflammatory drugs (NSAIDs) on ICI therapy. MethodsWe conducted a retrospective study of 381 patients with non-small cell lung cancer who received ICI therapy from January 1, 2016 to December 31, 2022. The primary endpoint was overall survival (OS) and the secondary endpoint was progression-free survival (PFS). Antacids included histamine type 2 receptor antagonists (H2RAs), PPIs, and potassium-competitive acid blockers (P-CABs). ResultsAntacids were administered to 218 patients, including 168 with PPIs, 37 with P-CABs, and 13 with H2RAs. Patients with antacids had worse median PFS and OS than those without antacids (PFS, 2.9 vs. 6.2 months; OS, 12.3 vs. 24.0 months), and those with PPIs, P-CABs, or H2RAs had similar results. However, there were no significant differences between patients with and without antacids when stratified by corticosteroid and NSAID use. Multivariate analyses showed that corticosteroids and NSAIDs administered for cancer-associated symptoms were related to poor prognosis, but antacids including PPIs, P-CABs, or H2RAs were not related. ConclusionsAntacids were not related to ICI efficacy when NSAIDs or corticosteroids were taken into consideration. This may be because the most frequent reason for administering NSAIDs and corticosteroids was cancer-associated symptoms, which are a poor prognostic factor, and most of the patients treated with these medications also received antacids.

Effect of Omega-3 Polyunsaturated Fatty Acid Supplementation on Clinical Outcome of Atopic Dermatitis in Children.

The use of omega-3 fatty acids (omega-3 FA) in the treatment of atopic dermatitis (AD) is an area of ongoing research. Some studies suggest that dietary supplementation with omega-3 FA can help manage symptoms of AD by reducing lesion severity, skin inflammation, dryness and itching, while others show no significant beneficial effect. The aim of this study was to evaluate the effect of omega-3 FA from fish oil in combination with gamma-linolenic acid (GLA) from blackcurrant seed oil in children with AD. This is a longitudinal, prospective, randomized, triple blind, placebo-controlled parallel clinical trial. The study was conducted during the 2-year period throughout autumn, winter, and spring, avoiding the summer when AD usually improves. Children were randomized to receive the active study product (Mega Kid®) containing a specific blend of omega-3 and omega-6 fatty acids or placebo. The primary outcomes were changes in severity of AD measured using SCORing Atopic Dermatitis (SCORAD), patient-oriented SCORAD (PO-SCORAD) and the difference in topical corticosteroid (TCS) use. The secondary outcomes were changes in itch intensity, sleep quality and Family Dermatology Life Quality Index (FDLQI). Data were analyzed for 52 children (26 in the intervention group and 26 in the placebo group). In children receiving the active product, intention-to-treat analysis showed that after 4 months of treatment, there was a significant decrease in the SCORAD index (from median 42 to 25, p < 0.001) and the use of topical corticosteroids (from median 30 to 10 mg/month, p < 0.001), but also significant improvements in itch, sleep quality, and overall quality of life. Omega-3 fatty acids in combination with GLA and vitamin D may decrease symptoms and were associated with an improvement clinical picture of AD in children. Therefore, we can conclude that supplementation with this specific combination could be considered a safe and effective intervention that may significantly reduce the severity of AD in pediatric patients.

Peripheral Blood Eosinophilia at Diagnosis of Inflammatory Bowel Disease Is Associated with Severe Disease Course; A Nationwide Study From the epi-IIRN Cohort.

We conducted this nationwide study to evaluate the association between peripheral blood eosinophilia (PBE) and long-term outcomes in children and adults with inflammatory bowel diseases (IBD). Data from the epi-IIRN cohort, a validated population-based IBD database, included patients diagnosed between 2005-2020 who had an eosinophil count at diagnosis, and those of non-IBD controls. PBE was defined as an eosinophil count of >0.5 X109/L Severe disease course was defined as corticosteroid dependency, use of ≥2 biologics from different classes, or surgery. Time-to-outcomes, including severe disease course, was determined by Cox proportional hazard models. Included were 28,133 patients (15,943 Crohn's disease [CD] and 12,190 ulcerative colitis [UC]), and 28,724 non-IBD controls. The prevalence of PBE was 13% in the IBD group and 5% in controls (P < .001). PBE was more prevalent in UC (16.1%) compared to CD (10.6%, OR=1.52 (95%CI 1.42-1.63); P < .001) and in pediatric-onset (23.5%) compared to adult-onset (11%) IBD (OR=2.14 (1.97-2.31); P <.001). In a multivariate analysis, PBE was a predictor of severe disease course in IBD (hazard ratio [HR]=1.49, 95%CI 1.38-1.62, P < .001). PBE also predicted time-to-hospitalization (HR=1.24, 95%CI 1.19-1.30), use of corticosteroids (HR=1.32, 95%CI 1.28-1.36), corticosteroid dependency (HR=1.37, 95%CI 1.31-1.43), and need of biologics (HR=1.27, 95%CI 1.21-1.33). In this largest nationwide study, PBE predicted severe IBD course. These findings support the use of PBE as a marker of adverse outcome of IBD and as a potential target for future therapies.

Risk Factors of COVID-19 associated mucormycosis in Iranian patients: a multicenter study

BackgroundTo evaluate the demographic, clinical, and prognostic characteristics of patients diagnosed with COVID-19-associated mucormycosis (CAM) in Iranian patients.MethodsThis prospective observational study was conducted in 8 tertiary referral ophthalmology centers in different provinces of Iran during the fifth wave of the COVID-19 pandemic. All patients were subjected to complete history taking and comprehensive ophthalmological examination and underwent standard accepted treatment strategy based on the disease stage.ResultsTwo hundred seventy-four CAM patients (most were males (150, 54.7%)) with a mean age of 56.8 ± 12.44 years were enrolled. Patients with a history of cigarette smoking (Adjusted Odds Ratio (AOR) = 4.36), Intensive Care Unit admission (ICU) (AOR = 16.26), higher stage of CAM (AOR = 2.72), and receiving endoscopic debridement and transcutaneous retrobulbar amphotericin B (AOR = 3.30) had higher odds of mortality. History of taking systemic corticosteroids during COVID-19 was significantly associated with reduced odds of mortality (AOR = 0.16). Generalized Estimating Equations analysis showed that the visual acuity of deceased patients (LogMAR: 3.71, 95% CI: 3.04–4.38) was worse than that of patients who were discharged from the hospital (LogMAR: 2.42, 95% CI: 2.16–2.68) (P < 0.001).ConclusionsThis study highlights significant risk factors for mortality in patients with CAM, such as cigarette smoking, ICU admission, advanced CAM stages, receiving transcutaneous retrobulbar amphotericin B and worser visual acuity. Conversely, a history of systemic corticosteroid use during COVID-19 was linked to reduced mortality. These findings underscore the critical need for early identification and targeted interventions for high-risk CAM patients to improve clinical outcomes.

Factors That Influence Clinician Prescribing of Corticosteroids for Acute Idiopathic and Multiple Sclerosis-Associated Optic Neuritis: A Qualitative Study.

Treatment with corticosteroids is common for patients with idiopathic and multiple sclerosis-associated optic neuritis (I/MS-ON). Yet, the Optic Neuritis Treatment Trial and meta-analyses confirm that few patients benefit and that visual benefit is of questionable clinical significance, short-lived, and comes with potential harms. The purpose of this study was to uncover the breadth of factors that underlie clinicians' treatment decisions and determine how these factors may influence corticosteroid use for I/MS-ON. We performed semistructured, one-on-one, qualitative interviews with neurologists, neuro-ophthalmologists, and emergency department clinicians at 15 academic and private practices across the United States. The interview guide used the Theoretical Domain Framework and a vignette to explore numerous factors that might influence decision making for definite I/MS-ON. We analyzed transcripts using inductive thematic analysis to generate themes. A total of 22 clinicians were interviewed before thematic saturation was reached: 8 neuro-ophthalmologists, 8 neurologists, and 6 emergency medicine (EM) clinicians (2 physician assistants, 4 physicians). All neuro-ophthalmologists and nearly all neurologists (7 of 8) were aware of risks/benefits of corticosteroid treatment for I/MS-ON. However, neuro-ophthalmologists varied in their corticosteroid treatment recommendation (n = 3 recommended treatment, n = 2 recommended observation, n = 3 recommended shared decision making), whereas all neurologists recommended corticosteroids, indicating that knowledge of corticosteroid risk/benefit alone does not drive decision making. EM clinicians were not aware of risk/benefits of corticosteroid treatment for I/MS-ON and relied on the treatment recommendations of neurologists. Clinicians recommending corticosteroids held personal beliefs that corticosteroids benefit those with worse vision loss, relieve pain, allow earlier return to work, or have easily mitigated side effects. They also perceived that prescribing steroid was the principal method of "doing something," which fit a key provider role. Clinicians who did not recommend corticosteroids or were neutral perceived the risks as nontrivial, considered discussing treatment trade-offs as "doing something" and incorporated patient preferences. Knowledge of risk/benefits of corticosteroids are necessary but not sufficient for evidence-based I/MS-ON practice. Variation in how clinicians treat patients with acute I/MS-ON is influenced largely by psychosocial factors, such as beliefs about corticosteroid risk/benefit trade-offs and the role of the clinician to provide treatment. Interventions to support evidence-based decision making for I/MS-ON treatment will need to provide risk/benefit information to support clinicians with varying levels of expertise, incorporate patient preference, and normalize the option to observe.
