The efficacy and safety of low-dose rituximab in the treatment of pemphigus vulgaris: a cohort study

BACKGROUND

Rituximab (RTX) is considered the first-line treatment for pemphigus vulgaris (PV), which is a B-cell-mediated acquired autoimmune disease. However, no consensus on the optimum dosage has been achieved.

OBJECTIVES

To investigate the efficacy and safety of low-dose RTX (a single infusion of 500 mg) for the treatment of PV, a cohort study was conducted for patients with PV, along with a 12-month follow-up following the administration of RTX.

METHODS

Patients with moderate or severe PV were divided into group A (low-dose RTX combined with corticosteroids) and group B (corticosteroids alone). Data on complete remission (CR) rates, doses of corticosteroids, cumulative doses of corticosteroids at the third, sixth, and twelfth months, pemphigus disease area index and adverse effects (AEs) were collected.

RESULTS

Forty-four patients with moderate or severe PV were enrolled in this study (19 in group A and 25 in group B). Patients treated with low-dose RTX had higher CR rates, lower doses of corticosteroids at the third, sixth, and twelfth months, lower cumulative doses of corticosteroids at the sixth and twelfth months, and fewer AEs than those who received corticosteroids alone.

CONCLUSIONS

This study indicated that low-dose RTX may be a beneficial and secure therapy option for patients with moderate to severe PV.

Key Articles and Guidelines in the Management of Pericardial Syndromes

Over the past two decades, emerging literature has shaped the management of pericardial syndromes and has evolved abundantly towards the creation of European guidelines for the diagnosis and management of pericardial diseases. However, since the publication of the European guidelines in 2015, more data surrounding the management of pericardial syndromes have been published. Comprehensive reference materials with the most updated literature are warranted and can be pivotal in helping pharmacists make evidence-based and clinical decisions for patients diagnosed with pericardial syndromes. This compilation of key articles and guidelines will serve as a resource for pharmacists who are responsible for the care of patients with pericardial syndromes.

Clinical efficacy of intense pulsed light combined with low-dose intralesional corticosteroids in treating noninfectious granulomas after mesotherapy: A case series analysis

BACKGROUND

Mesotherapy is a popular cosmetic procedure for localized delivery of substances. However, due to the lack of standardized processes, there are potential risks of adverse reactions. Granulomas formation is one of the chronic reactions which impose significant physical and mental burdens on patients.

OBJECTIVES

The aim of this analysis is to evaluate the safety and feasibility of combining intense pulsed light (IPL) with intralesional corticosteroids for treating noninfectious granulomas after mesotherapy.

METHODS

This retrospective observational case series included patients who suffer from noninfectious granulomas after mesotherapy and received combination of IPL and intralesional corticosteroids treatment between October 2021 and December 2022 at Peking University Shenzhen Hospital, Shenzhen, China. The process and effect were analyzed and summarized.

RESULTS

Among the seven patients, five expressed extreme satisfaction with the efficacy, while two was slightly satisfied. The physicians believed that all patients had shown significant improvement. No adverse reactions or recurrences were observed during follow-up.

CONCLUSION

Based on this analysis, the application of the combined treatment in patients suffering from noninfectious granuloma due to mesotherapy demonstrates good clinical efficacy and safety, making it worth considering as a treatment option.

Guidelines of care for the management of acne vulgaris

BACKGROUND

Acne vulgaris commonly affects adults, adolescents, and preadolescents aged 9 years or older.

OBJECTIVE

The objective of this study was to provide evidence-based recommendations for the management of acne.

METHODS

A work group conducted a systematic review and applied the Grading of Recommendations, Assessment, Development, and Evaluation approach for assessing the certainty of evidence and formulating and grading recommendations.

RESULTS

This guideline presents 18 evidence-based recommendations and 5 good practice statements. Strong recommendations are made for benzoyl peroxide, topical retinoids, topical antibiotics, and oral doxycycline. Oral isotretinoin is strongly recommended for acne that is severe, causing psychosocial burden or scarring, or failing standard oral or topical therapy. Conditional recommendations are made for topical clascoterone, salicylic acid, and azelaic acid, as well as for oral minocycline, sarecycline, combined oral contraceptive pills, and spironolactone. Combining topical therapies with multiple mechanisms of action, limiting systemic antibiotic use, combining systemic antibiotics with topical therapies, and adding intralesional corticosteroid injections for larger acne lesions are recommended as good practice statements.

LIMITATIONS

Analysis is based on the best available evidence at the time of the systematic review.

CONCLUSIONS

These guidelines provide evidence-based recommendations for the management of acne vulgaris.

A Randomized Controlled Trial of Betamethasone on Fatigue in Patients With Advanced Cancer

CONTEXT

Fatigue is one of the most uncomfortable physical symptoms seen in patients with advanced cancer. Previous studies have reported on the efficacy of corticosteroids from Western countries.

OBJECTIVES

To assess the effectiveness of 4mg betamethasone improving fatigue among Japanese patients with advanced cancer.

METHODS

A randomized, double-blind, placebo-controlled trial enrolled eligible patients with advanced cancer expected to survive 1-2 months, with an Eastern Cooperative Oncology Group Performance Status of 2-3, and experiencing fatigue according to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-15-palliative criteria. Participants received twice-daily oral administration of 2 mg betamethasone (4 mg/d) or placebo for seven days, with fatigue assessed using EORTC QLQ-C15-PAL subscale and numerical rating scale (NRS) score (at baseline and day seven). The trial was registered under the University Hospital Medical Information Network (UMIN)000011913.

RESULTS

Among the 267 screened patients, 81 were eligible, of which 70 were evaluable (betamethasone, 33; placebo, 37). The mean difference in the EORTC-QLQ-C15-PAL fatigue subscale was -8.2 (95% CIs: -22.3, 0.0; P = 0.178) and in a NRS for fatigue was -1.2 (95% CIs: -2.5, -0.01; P = 0.048), respectively. Emotional function, appetite loss, and global-health were slightly better in the betamethasone group than in the placebo group.

CONCLUSION

The impact of betamethasone 4 mg/d on alleviating fatigue in patients with advanced cancer in the last weeks of life did not reach statistical significance in the EORTC-QLQ-C15-PAL as the primary endpoint, however, it was significant in the NRS, the secondary endpoint.

Dexamethasone sodium phosphate loaded nanoparticles for prevention of nitrogen mustard induced corneal injury

Nitrogen mustard (NM) is a potent vesicating chemical warfare agent that is primarily absorbed through skin, inhalation, or ocular surface. Ocular exposure of NM can cause acute to chronic keratopathy which can eventually lead to blindness. There is a current lack of effective countermeasures against ocular exposure of NM despite their imperative need. Herein, we aim to explore the sustained effect of Dexamethasone sodium phosphate (DSP)-loaded polymeric nanoparticles (PLGA-DSP-NP) following a single subconjunctival injection in the management and prevention of corneal injury progression upon exposure to NM. DSP is an FDA approved corticosteroid with proven anti-inflammatory properties. We formulated PLGA-DSP-NP with zinc chelation ion bridging method using PLGA polymer, with particles of approximately 250 nm and a drug loading of 6.5 wt%. Under in vitro sink conditions, PLGA-DSP-NP exhibited a sustained drug release for two weeks. Notably, in NM injured cornea, a single subconjunctival (SCT) injection of PLGA-DSP-NP outperformed DSP eyedrops (0.1%), DSP solution, placebo NP, and saline, significantly mitigating corneal neovascularization, ulceration, and opacity for the two weeks study period. Through PLGA-DSP-NP injection, sustained DSP release hindered inflammatory cytokine recruitment, angiogenic factors, and endothelial cell proliferation in the cornea. This strategy presents a promising localized corticosteroid delivery system to effectively combat NM-induced corneal injury, offering insights into managing vesicant exposure.

A Roadmap for Using Causal Inference and Machine Learning to Personalize Asthma Medication Selection

Inhaled corticosteroid (ICS) is a mainstay treatment for controlling asthma and preventing exacerbations in patients with persistent asthma. Many types of ICS drugs are used, either alone or in combination with other controller medications. Despite the widespread use of ICSs, asthma control remains suboptimal in many people with asthma. Suboptimal control leads to recurrent exacerbations, causes frequent ER visits and inpatient stays, and is due to multiple factors. One such factor is the inappropriate ICS choice for the patient. While many interventions targeting other factors exist, less attention is given to inappropriate ICS choice. Asthma is a heterogeneous disease with variable underlying inflammations and biomarkers. Up to 50% of people with asthma exhibit some degree of resistance or insensitivity to certain ICSs due to genetic variations in ICS metabolizing enzymes, leading to variable responses to ICSs. Yet, ICS choice, especially in the primary care setting, is often not tailored to the patient's characteristics. Instead, ICS choice is largely by trial and error and often dictated by insurance reimbursement, organizational prescribing policies, or cost, leading to a one-size-fits-all approach with many patients not achieving optimal control. There is a pressing need for a decision support tool that can predict an effective ICS at the point of care and guide providers to select the ICS that will most likely and quickly ease patient symptoms and improve asthma control. To date, no such tool exists. Predicting which patient will respond well to which ICS is the first step toward developing such a tool. However, no study has predicted ICS response, forming a gap. While the biologic heterogeneity of asthma is vast, few, if any, biomarkers and genotypes can be used to systematically profile all patients with asthma and predict ICS response. As endotyping or genotyping all patients is infeasible, readily available electronic health record data collected during clinical care offer a low-cost, reliable, and more holistic way to profile all patients. In this paper, we point out the need for developing a decision support tool to guide ICS selection and the gap in fulfilling the need. Then we outline an approach to close this gap via creating a machine learning model and applying causal inference to predict a patient's ICS response in the next year based on the patient's characteristics. The model uses electronic health record data to characterize all patients and extract patterns that could mirror endotype or genotype. This paper supplies a roadmap for future research, with the eventual goal of shifting asthma care from one-size-fits-all to personalized care, improve outcomes, and save health care resources.

Roflumilast foam (Zoryve) for seborrheic dermatitis

The FDA has approved a 0.3% foam formulation of the phosphodiesterase-4 (PDE4) inhibitor roflumilast (Zoryve – Arcutis) for topical treatment of seborrheic dermatitis in patients ≥9 years old. Roflumilast is the first PDE4 inhibitor to be approved in the US for this indication.

Idiopathic intracranial hypertension as the initial presenting manifestation of systemic lupus erythematosus in a child

Idiopathic intracranial hypertension (IIH) is a diagnosis of exclusion characterized by features of raised intracranial pressure (ICP) in the absence of brain parenchymal lesion, vascular malformations, hydrocephalus, or central nervous system (CNS) infection. Commonly used other terms for this entity include benign intracranial hypertension (BIH) or pseudotumor cerebri. Few case reports of systemic lupus erythematosus (SLE) presenting as IIH are available in the literature. We report a 12-year-old girl presented with chronic holocranial headache and occasional episodes of projectile vomiting for the last 6 months and then developed blurring of vision for the last month. She fulfilled the criteria for IIH. Subsequent evaluation revealed a diagnosis of SLE. The occurrence of IIH in SLE is not coincidental and is reported in 1%-5.4% of patients with SLE. Though corticosteroids have not been widely used in IIH, underlying SLE warranted administering corticosteroids with subsequent complete resolution of IIH. Pediatricians, neurologists, intensivists, and ophthalmologists should consider SLE as a differential diagnosis in children presenting with IIH.

Dupilumab in adolescent eosinophilic esophagitis: Experience with fibrostenosis and EGID with esophageal involvement

We evaluated patients aged 12-20 on dupilumab 300 mg weekly for treatment of eosinophilic esophagitis (EoE) who had ≥1 follow-up endoscopy at a tertiary care pediatric hospital (n = 18). Fifty percent had inflammatory EoE (n = 9), 22% had fibrostenotic EoE (n = 4), and 28% had non-EoE eosinophilic gastrointestinal disease (EGID) with esophageal involvement (n = 5). Ninety-four percent discontinued topical corticosteroids (TCS) 2-4 weeks after starting dupilumab. Eighty-nine percent of inflammatory EoE patients had histological response (<15 eosinophils/high-powered field) after an average of 19.1 weeks. One hundred percent of patients with fibrostenotic disease exhibited histological response after 16.8 weeks. Of patients with non-EoE EGID, 60% achieved esophageal histological response after an average of 40.1 weeks. In a small cohort, dupilumab was very effective for adolescent inflammatory and fibrostenotic EoE despite rapid weaning of TCS. Dupilumab was also somewhat effective for non-EoE EGID with esophageal involvement; however, a longer duration of therapy was required.

Glucocorticoid treatment in SLE is associated with infections, comorbidities and mortality-a national cohort study

OBJECTIVES

Patients with SLE have an increased risk of comorbidities and impaired survival. We aimed to assess whether various thresholds of oral CS (OCS) can predict development of infections, comorbidities, malignancies and survival in SLE using data from national health registries in Sweden.

METHODS

All incident SLE cases, age >18 years, in Sweden (n = 5309) between 2005 and 2020 and matched population controls (n = 26 545) were included and followed until 2020, a total of 257 942 patient years. Data from national registers were retrieved including information from the National Prescribed Drug Register. Risk factors were analysed using time-dependent Cox regression models.

RESULTS

Compared with no OCS, >0 to <5.0 mg/day, 5.0-7.5 mg/day as well as >7.5 mg/day OCS predicted development of infections (pneumonia, influenza, herpes zoster and urinary tract infection), osteoporosis, osteonecrosis, gastroduodenal ulcers, cataracts, hypertension and mortality (all P < 0.05). OCS >0 to <5.0 mg/day was associated with lower hazard ratios for these comorbidities than higher doses of OCS. Fifteen years after diagnosis, 48% of patients were taking OCS at a median dose of 5.7 mg/day. A small reduction of OCS treatment 5 years after diagnosis in patients diagnosed with SLE 2006-10 compared with 2011-15 was observed, 49% vs 46% respectively (P = 0.039).

CONCLUSION

Results highlight the potential harm associated with even low OCS dose treatment in SLE and the need to judiciously use OCS at the lowest possible dose to maximize efficacy and minimize harm.

Do We Need to Administer Fludrocortisone in Addition to Hydrocortisone in Adult Patients With Septic Shock? An Updated Systematic Review With Bayesian Network Meta-Analysis of Randomized Controlled Trials and an Observational Study With Target Trial Emulation

OBJECTIVES

This systematic review and Bayesian network meta-analysis evaluated the efficacy and safety of hydrocortisone combined with fludrocortisone or hydrocortisone alone, compared with placebo in adult patients with septic shock.

DATA SOURCES

By extending a prior Cochrane review, databases, including PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov , along with other relevant websites, were searched until August 31, 2023.

STUDY SELECTION

Randomized controlled trials (RCTs) and observational studies using target trial emulation were included.

DATA EXTRACTION

The primary outcome was short-term mortality with an emphasis on 28- or 30-day mortality as the main measure and in-hospital or ICU mortality as the nearest surrogate of this measure. Three of the most common adverse events, namely, gastroduodenal bleeding, superinfection, and hyperglycemia, were also considered.

DATA SYNTHESIS

A total of 19 studies involving 95,841 patients were included. Hydrocortisone plus fludrocortisone showed the lowest short-term mortality versus placebo (odds ratio [OR]: 0.79; 95% credible interval [CrI], 0.64-0.99; number needed to treat [NNT]: 21, range: 12-500; low certainty of evidence) in terms of informative priors. The surface under the cumulative ranking curve values for hydrocortisone plus fludrocortisone, hydrocortisone alone, and placebo were 0.9469, 0.4542, and 0.0989, respectively. Consistent results were observed in RCTs alone and those using a daily 200-mg dose of hydrocortisone. Although gastroduodenal bleeding or superinfection showed no clear increase, hyperglycemia risk increased. The ORs were 0.53 for placebo versus hydrocortisone plus fludrocortisone and 0.64 for placebo versus hydrocortisone alone, with very low certainty of evidence.

CONCLUSIONS

In adults with septic shock, hydrocortisone plus fludrocortisone improved short-term survival with minimal adverse events compared with hydrocortisone alone or placebo. However, these findings are not definitive due to the limited certainty of evidence and wide NNT range. Additional large-scale, placebo-controlled RCTs are needed to provide conclusive evidence.

Measuring neurobehavioral side effects of corticosteroids in pediatric acute lymphoblastic leukemia: A scoping review

Corticosteroids are essential to curative acute lymphoblastic leukemia (ALL) treatment, yet have significant neuropsychiatric side effects that decrease quality of life for patients and families. We conducted a scoping review, following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, to describe the existing measurement tools used to evaluate neurobehavioral side effects of corticosteroids in pediatric ALL. From various databases and registers, 4047 studies were identified. Twenty-four articles met inclusion criteria. Clinical assessment was most used to evaluate these symptoms. Twelve validated measures were identified. Existing data about neuropsychiatric side effects of corticosteroids in pediatric ALL are extremely heterogeneous, creating challenges for standardized assessment and management.

Navigating the complexity of Churg-Strauss syndrome presenting as acute abdomen: a comprehensive review and case report

Introduction and importance

Churg-Strauss syndrome (CSS) is a rare multisystemic condition characterized by asthma, blood and tissue eosinophilia, and vasculitis. The purpose of this work is to present a detailed overview of CSS, focusing on its epidemiology, clinical symptoms, histological criteria, gastrointestinal involvement, and therapy.

Case presentation

The authors report a case of a 40-year-old woman with CSS who had peripheral eosinophilia, small vessel vasculitis, and bronchial asthma. Diagnosed with symmetric polyarthritis six months ago, experienced abdominal pain, vomiting, and loose faeces. Diagnostic tests revealed CSS with systemic involvement. In addition, we undertake a literature analysis to emphasize essential elements of CSS, such as its rarity and the difficulties in diagnosing and managing it.

Clinical discussion

CSS can cause gastrointestinal symptoms including stomach pain, diarrhoea, mucosal ulcers, rectal bleeding, and bowel perforations. Corticosteroids and immunosuppressives are routinely used in treatment, with caution due to the risks of long-term steroid use. The goal of treatment should be to induce remission while minimizing side effects.

Conclusion

CSS is a rare condition, with an annual incidence of 2.4 per million and a prevalence of 1.3 per 100 000. The illness typically presents with necrotizing vasculitis, extravascular granulomas, and eosinophilic tissue infiltration. CSS is a complex and rare condition that requires high clinical suspicion, especially when patients present with gastrointestinal symptoms in addition to asthma and eosinophilia. This case study adds to our understanding of CSS and emphasizes the significance of a holistic strategy for its management.

Risk of fractures and use of bisphosphonates in adult patients with immune thrombocytopenia-A nationwide population-based study

Corticosteroids remain the first-line treatment of immune thrombocytopenia (ITP), but increase the risk of osteoporosis and fractures. Bisphosphonates are used for the treatment of osteoporosis, but their usage among patients with ITP has not been systemically described. We investigated the risk of fractures and the use of bisphosphonates in adult patients with primary (pITP) and secondary ITP (sITP) compared with matched comparators in a nationwide registry-based cohort study. We identified 4030 patients with pITP (median age 60 years [IQR, 40-74]), 550 with sITP (median age 59 years [IQR, 43-74]) and 182 939 age-sex-matched general population comparators. All individuals were followed for incident fractures. Bisphosphonate use was estimated for calendar-years and in temporal relation to the ITP diagnosis. Adjusted cause-specific hazard ratio (csHR) for any fracture was 1.37 (95% confidence interval [CI] 1.23; 1.54) for pITP and 1.54 (1.17; 2.03) for sITP. The first-year csHR was 1.82 (1.39; 2.40) for pITP and 2.78 (1.58; 4.91) for sITP. Bisphosphonate use over calendar-years and in the early years following ITP diagnosis was higher among patients with ITP diagnosis compared with the general population. In conclusion, the risk of fractures and the use of bisphosphonates are higher in patients with ITP compared with the general population.

The role of budesonide intrapolyp injection in the management of type 2 chronic rhinosinusitis with nasal polyps: a randomised clinical trial

PROBLEM

To assess the efficacy of budesonide intrapolyp injection in chronic rhinosinusitis with nasal polyps.

METHOD

Ninety patients were divided into three groups; group A was given oral prednisolone, group B was given budesonide intrapolyp injection weekly for five consecutive weeks and group C was given budesonide as nasal irrigation for one month. Patients were assessed using Sino-Nasal Outcome Test 22 score, total nasal polyp score, serum immunoglobulin E, absolute eosinophilic count, and morning cortisol level before treatment, one week and three months after completing their treatment.

RESULTS

Total nasal polyp score decreased significantly in all groups compared to those at baseline. Reduction in the oral and injection groups was greater than the wash group (p2 = 0.004), (p3 < 0.001), and the same trend concerning Sino-Nasal Outcome Test 22 score (p2 < 0.001), (p3 < 0.001).

CONCLUSION

Budesonide is an effective agent used in intrapolyp injection with no documented systemic or visual side effects that has comparable results with oral steroids.

Therapeutic Efficacy of Nasal Corticosteroids in COVID-19-Related Olfactory Dysfunction: A Comprehensive Systematic Review and Meta-analysis

OBJECTIVE

Olfactory disturbance is one of the main symptoms of coronavirus disease-2019 (COVID-19). Various olfactory disorders caused by viral infections are treated with nasal corticosteroids. This study aimed to evaluate the safety and efficacy of nasal corticosteroids in the treatment of olfactory disorders caused by the severe acute respiratory syndrome coronavirus 2.

DATA SOURCES

We searched the Web of Science, Embase, PubMed, and Cochrane Library databases for clinical trials of nasal corticosteroids for treating COVID-19 olfactory dysfunction.

REVIEW METHODS

We assessed the effect of nasal corticosteroids on olfactory function in COVID-19-affected individuals using a Meta-analysis of published studies, considering the number of patients who fully recovered from olfactory dysfunction, olfactory scores following treatment, and olfactory recovery time.

RESULTS

Seven studies involving 930 patients were analyzed. The Meta-analysis results revealed that the olfactory score of the experimental group was 1.40 points higher than that of the control group (standardized mean difference [MD]: 1.40, 95% confidence interval [95% CI]: 0.34-2.47, P < .00001). However, the differences in the outcomes of cure rate (risk ratio: 1.18, 95% CI: 0.89-1.69, P = .21) and recovery time (MD: -1.78, 95% CI: -7.36 to 3.81, P = .53) were not statistically significant. Only 1 study reported adverse effects of nasal steroid treatment, namely tension, anger, and stomach irritation.

CONCLUSION

Although nasal steroid therapy does not result in significant adverse effects, it proves ineffective in the treatment of COVID-19 olfactory dysfunction.

Factors Associated with Inhaled Bronchodilator and Oral Corticosteroid Use in Young Children with First Lower Respiratory Tract Infection

OBJECTIVES

To examine factors associated with claims for and potential overuse of inhaled bronchodilators (IBs) and oral corticosteroids (OCSs) for children <2 years old at first lower respiratory tract infections (LRTIs).

STUDY DESIGN

Retrospective cohort study using Colorado All Payer Claims data from 2009 through 2019. Children with asthma were excluded. Primary outcomes were 1) IB and 2) OCS claims within 7 days of index LRTI. Primary predictors were previous IB or OCS claims for each outcome respectively. Covariates included demographics, atopy, family history of asthma, complex chronic conditions, prior inhaled corticosteroid claim, and location of index LRTI. Separate multivariable logistic regression models were used for each outcome.

RESULTS

Of 10 194 eligible children, 1468 (14.4%) had an IB and 741 (7.3%) an OCS claim at or within 7 days of index LRTI. Index LRTIs were most often at outpatient visits (64%). Adjusting for covariates, prior IB prescription was associated with the IB outcome (aOR 1.9; 95% CI 1.3, 2.8), and prior OCS prescription was associated with the OCS outcome (AOR 2.2; 95% CI 1.7, 2.9). Other variables associated with either outcome included age, sex, insurance, location, and atopy. Prior inhaled corticosteroid claim, asthma family history, and complex chronic conditions were not associated with either outcome.

CONCLUSIONS

This study identifies factors that might serve as opportunities for de-implementation strategies for IB and OCS overuse in young children with LRTI.

Adverse Effects Related to Corticosteroid Use in Sepsis, Acute Respiratory Distress Syndrome, and Community-Acquired Pneumonia: A Systematic Review and Meta-Analysis

OBJECTIVES

We postulate that corticosteroid-related side effects in critically ill patients are similar across sepsis, acute respiratory distress syndrome (ARDS), and community-acquired pneumonia (CAP). By pooling data across all trials that have examined corticosteroids in these three acute conditions, we aim to examine the side effects of corticosteroid use in critical illness.

DATA SOURCES

We performed a comprehensive search of MEDLINE, Embase, Centers for Disease Control and Prevention library of COVID research, CINAHL, and Cochrane center for trials.

STUDY SELECTION

We included randomized controlled trials (RCTs) that compared corticosteroids to no corticosteroids or placebo in patients with sepsis, ARDS, and CAP.

DATA EXTRACTION

We summarized data addressing the most described side effects of corticosteroid use in critical care: gastrointestinal bleeding, hyperglycemia, hypernatremia, superinfections/secondary infections, neuropsychiatric effects, and neuromuscular weakness.

DATA SYNTHESIS

We included 47 RCTs (n = 13,893 patients). Corticosteroids probably have no effect on gastrointestinal bleeding (relative risk [RR], 1.08; 95% CI, 0.87-1.34; absolute risk increase [ARI], 0.3%; moderate certainty) or secondary infections (RR, 0.97; 95% CI, 0.89-1.05; absolute risk reduction, 0.5%; moderate certainty) and may have no effect on neuromuscular weakness (RR, 1.22; 95% CI, 1.03-1.45; ARI, 1.4%; low certainty) or neuropsychiatric events (RR, 1.19; 95% CI, 0.82-1.74; ARI, 0.5%; low certainty). Conversely, they increase the risk of hyperglycemia (RR, 1.21; 95% CI, 1.11-1.31; ARI, 5.4%; high certainty) and probably increase the risk of hypernatremia (RR, 1.59; 95% CI, 1.29-1.96; ARI, 2.3%; moderate certainty).

CONCLUSIONS

In ARDS, sepsis, and CAP, corticosteroids are associated with hyperglycemia and probably with hypernatremia but likely have no effect on gastrointestinal bleeding or secondary infections. More data examining effects of corticosteroids, particularly on neuropsychiatric outcomes and neuromuscular weakness, would clarify the safety of this class of drugs in critical illness.

Approaches Towards Better Immunosuppressive Agents

Several classes of compounds are applied in clinics due to their immunosuppressive properties in transplantology and the treatment of autoimmune diseases. Derivatives of mycophenolic acid, corticosteroids and chemotherapeutics bearing heterocyclic moieties like methotrexate, azathioprine, mizoribine, and ruxolitinib are active substances with investigated mechanisms of action. However, improved synthetic approaches of known drugs and novel derivatives are still being reported to attempt better accessibility and therapeutic properties. In this review article, we present the synthesis of the designed chemical structures based on recent literature reports concerning novel compounds as promising immunosuppressive drugs. Moreover, some of the discussed derivers revealed also other types of activities with prospective medicinal potential.

Steroid versus placebo injections and wrist splints in patients with carpal tunnel syndrome: a systematic review and network meta-analysis

A network meta-analysis of randomized controlled trials compared the effectiveness of corticosteroid injections with placebo injections and wrist splints for carpal tunnel syndrome, focusing on symptom relief and median nerve conduction velocity. Within 3 months of the corticosteroid injection, there was a modest statistically significant difference in symptom relief compared to placebo injections and wrist splints, as measured by the Symptom Severity Subscore of the Boston Carpal Tunnel Questionnaire; however, this did not meet the minimum clinically important difference. Pain reduction with corticosteroids was slightly better than with wrist splints, but it also failed to reach clinical significance. Electrodiagnostic assessments showed transient changes in distal motor and sensory latencies in favour of corticosteroids at 3 months, but these changes were not evident at 6 months. The best current evidence suggests that corticosteroid injections provide minimal transient improvement in nerve conduction and symptomatology compared with placebo or wrist splints.

Mepolizumab and benralizumab in patients with severe asthma and a history of eosinophilic granulomatosis with polyangiitis

Introduction

Asthma associated with eosinophilic granulomatosis with polyangiitis (EGPA) is often severe and corticosteroid-dependent, leading to significant morbidity. Mepolizumab and benralizumab are humanized monoclonal antibodies targeting interleukin 5 (IL-5) and its receptor, respectively. They have been shown to be effective in steroid-sparing in patients with severe eosinophilic asthma.

Objective

Our aim was to evaluate the efficacy and safety of mepolizumab and benralizumab prescribed for severe asthma in patients with EGPA under "real-world" conditions.

Methods

This was a retrospective analysis of patients with EGPA and persistent asthma who received either mepolizumab 100 or 300 mg administered every 4 weeks, or benralizumab 30 mg administered every 4 weeks for the initial 3 injections and followed by an injection every 8 weeks thereafter, whilst combined with oral glucocorticoids. The follow-up every 6 ± 3 months included an assessment of clinical manifestations, pulmonary function tests and eosinophil cell count. The primary outcome was the proportion of patients at 12 months receiving a daily oral dose of prednisone or equivalent of 4 mg or less with a BVAS of 0.

Results

Twenty-six patients were included. After 12 months of treatment with mepolizumab or benralizumab, 32% of patients met the primary outcome and were receiving less than 4 mg of prednisone per day with a BVAS of 0. The median dose of prednisone was 10 mg per day at baseline, 9 mg at 6 months, and 5 mg at 12 months (p ≤ 0.01). At 12 months, 23% of patients were weaned off corticosteroids, while an increase or no change in dose was observed in 27% of patients. The median eosinophil count was significantly reduced from 365 cells/mm3 to 55 cells/mm3 at 6 months and 70 cells/mm3 at 12 months, respectively. No significant change was observed in FEV1. After 12 months of treatment, 14% of patients had had an average of 1 exacerbation of asthma, compared with 52% of patients before baseline. The tolerability profile was favorable.

Conclusion

In this real-world study in patients with severe asthma and a history of EGPA asthma, mepolizumab and benralizumab had a significant steroid-sparing effect and reduced asthma exacerbation, but no significant effect on lung function.

Adrenal insufficiency following cerebellar intracranial hemorrhage: a case report

This report presents a case of a previously healthy 58 years-old man who had suffered from persistent weakness and dizziness after a cerebellar intracranial hemorrhage (ICH). Endocrine function tests revealed low levels of plasma cortisol (3.05 μg/dL; normal range: 5-25 μg/dL) and adrenocorticotropic hormone (ACTH) (6.0 pg/mL; normal range: 10-60 pg/mL). The subsequent ACTH stimulation test suggested partial or recent hypopituitarism, resulting in adrenal gland atrophy and a subnormal cortisol response. Ultimately, the dizziness was found to be caused by undiagnosed adrenal insufficiency, which was detected when a hypotensive fainting incident occurred during rehabilitation. The symptoms improved significantly with oral prednisone supplementation. Notably, the duration of impaired hypothalamic-pituitary-adrenal axis may last as long as a year. This case highlights that adrenal insufficiency can easily be overlooked since its symptoms are similar to those commonly seen with cerebellar stroke alone. Physicians must be aware of the symptoms of adrenal insufficiency in patients with brain insults and conduct the appropriate endocrine tests to clarify the underlying comorbidity.

Chorioretinopathy Post COVID-19: A Systematic Review and Prevalence Assessment, Unveiling Insights into an Emerging Ocular Entity

PURPOSE

To investigate the occurrence of chorioretinopathy post-COVID-19, emphasizing demographic characteristics, medication history, clinical presentation, diagnostic evaluation, and treatment approaches, with a specific focus on the role of corticosteroid use.

METHODS

Our protocol was registered prospectively on PROSPERO (CRD42023457712). A systematic search of databases (PubMed, Cochrane, WOS, Scopus) from November 2020 to August 2023 were performed to identify any original research reporting chorioretinopathy in COVID-19 patients. Data extraction included patient demographics, COVID-19 timeline, medication history, symptoms, diagnostic tests, and treatment outcomes. We used Joanna Briggs Institute (JBI) critical appraisal tool to assess the quality of our included studies.

RESULTS

We identified seven case reports and two case series including 10 patients, six females and four males (mean age 36.5 years), who exhibited chorioretinopathy after COVID-19. Onset varied from 6 days to three months post-infection (average = 24.3 days). Seven patients (70%) had a history of corticosteroid use during COVID-19 treatment. Symptoms included visual loss, blurred vision, and deterioration. Diagnostic assessments revealed central serous chorioretinopathy in seven patients (70%) and punctate inner choroidopathy in two (20%). Treatment approaches varied, with corticosteroid discontinuation leading to symptom improvement, while two patients were treated with corticosteroids. Five patients who discontinued corticosteroids were reported to have improvement in visual acuity, two of them changed to 20/25 after being 20/40, two changed to 6/6, and one changed to 20/20, while the visual acuity in the sixth patient was not reported. Regarding the two patients who were treated with corticosteroids, visual acuity was reported in one case only and it improved to 20/20.

CONCLUSION

This systematic review states the prevalence and potential association between chorioretinopathy, and corticosteroid use in the context of COVID-19. This relation is still unclear because of the relief of symptoms in some cases after corticosteroid discontinuation, while two other cases were treated with corticosteroids and their symptoms improved.

MRI spectrum of avascular necrosis of femoral head in patients treated for COVID-19

BACKGROUND AND PURPOSE

This prospective observational study aimed to investigate the occurrence of avascular necrosis (AVN) of the femoral head in COVID-19 patients through MRI scans. The study examined the patterns of AVN in 110 individuals who had undergone conventional COVID-19 therapy and reported hip discomfort. This study highlights the importance of considering AVN as a potential complication of COVID-19 therapy, particularly in younger patients who experience hip discomfort.

METHODS

Individuals who had corticosteroid treatment for COVID-19 and experienced hip discomfort during 6 months between January 2022 and August 2022 were included in this study, and an MRI scan was done to observe changes in the hip joint.

RESULTS

The results were classified using the Ficat and Arlet classification system. The analysis revealed that AVN was not present in 91.81% of cases. However, Stage I AVN was detected in 4.54% of cases, Stage II AVN in 2.72% of cases, and Stage III AVN in 1.1% of cases. No cases of Stage IV AVN were observed.

CONCLUSIONS

The study concludes that AVN occurred in 6% of individuals who underwent conventional therapy for COVID-19 and experienced hip discomfort. In these settings (post COVID-19), normal MRI results were more typical, and mild AVN (Stage I) was a frequent finding in MRI scans that were positive.

ANGPTL7 and Its Role in IOP and Glaucoma

Purpose

Loss-of-function variants in the ANGPTL7 gene are associated with protection from glaucoma and reduced intraocular pressure (IOP). We investigated the role of ANGPTL7 in IOP homeostasis and its potential as a target for glaucoma therapeutics.

Methods

IOP, outflow facility, and outflow tissue morphology of Angptl7 knockout (KO) mice were assessed with and without dexamethasone (Dex). ANGPTL7 was quantified in conditioned media from human trabecular meshwork cells in response to Dex, in effluent from perfused human donor eyes, and in aqueous humor from human patients treated with steroids. Antibodies to ANGPTL7 were generated and tested in three-dimensional (3D) culture of outflow cells and perfused human donor eyes. Rabbits were injected intravitreally with a neutralizing antibody targeting ANGPTL7, and IOP was measured.

Results

IOP was significantly elevated, but outflow facility and outflow tissue morphology were not different between Angptl7 KO mice and littermates. When challenged with Dex, IOP increased in wild-type but not Angptl7 KO mice. In human samples, increased ANGPTL7 was seen in the aqueous humor of patients treated with steroids, regardless of glaucoma status. Using 3D culture, recombinant ANGPTL7 decreased, and ANGPTL7-blocking antibodies increased hydraulic conductivity. Significantly, outflow facility increased in human eyes treated ex vivo with ANGPTL7-blocking antibodies, and IOP decreased for 21 days in rabbits after a single injection of blocking antibodies.

Conclusions

Using multiple models, we have demonstrated that excess ANGPTL7 increases outflow resistance and IOP and that neutralizing ANGPTL7 has beneficial effects in both naïve and steroid-induced hypertensive eyes, thus motivating the development of ANGPTL7-targeting therapeutics for the treatment of glaucoma.

Ulcerative sarcoidosis: An atypical cause of leg ulcers

We present the case of an 83-year-old woman with leg ulcers who was diagnosed with sarcoidosis. This case highlights the importance for clinicians to consider ulcerative sarcoidosis when encountering patients with leg ulcers along with hilar adenopathy, uveitis, elevated serum angiotensin-converting enzyme, and histopathological findings of epithelioid cell granulomas.

Role of dexamethasone in controlling the proinflammatory cytokine cascade in the first episode of paediatric acute pyelonephritis

AIM

Febrile urinary tract infection is a common bacterial infection in childhood. The kidney damage after acute pyelonephritis (APN) could be related to the stimulation of the proinflammatory response. We aimed to investigate the role of inflammatory cytokines and the effect of dexamethasone after a first episode of APN.

METHODS

Subanalysis of the DEXCAR RCT in which children with confirmed APN (1 month-14 years) were randomly assigned to receive a 3 days course of either intravenous dexamethasone or placebo. Urinary cytokine levels at diagnosis and after 72 h of treatment were measured.

RESULTS

Ninety-two patients were recruited. Younger patients, males and those with abnormalities in the ultrasound study or vesicoureteral reflux showed higher values of urinary cytokines. Patients with severe APN had higher Tumour Necrosis Factor (TNF)α levels (81.0 ± 75.8 vs. 33.6 ± 48.5 pg/mg creatinine, p = 0.015). Both intervention groups showed similar basal clinical characteristics, including urinary cytokine levels. Treatment reduced urinary cytokine levels irrespective of dexamethasone administration. Neither the intervention group nor the urinary cytokine levels modulated the development of kidney scars.

CONCLUSION

Basal urinary cytokines were associated with age, abnormal ultrasound and vesicoureteral reflux. Patients with severe APN had higher TNFa urinary levels. Administration of dexamethasone in children with APN does not improve the control of the proinflammatory cytokine cascade.

A Comparative Review of Typical and Atypical Optic Neuritis: Advancements in Treatments, Diagnostics, and Prognosis

Optic neuritis (ON) is a debilitating condition that through various mechanisms, including inflammation or demyelination of the optic nerve, can result in partial or total permanent vision loss if left untreated. Accurate diagnosis and promptly initiated treatment are imperative related to the potential of permanent loss of vision if left untreated, which can lead to a significant reduction in the quality of life in affected patients. ON is subtyped as "typical" or "atypical" based on underlying causative etiology. The etiology of ON can be differentiated when appropriate diagnostic testing is performed. Using history taking, neuroimaging, and visual testing to localize the underlying pathology of ON in a time-sensitive manner is critical in mitigating these unsatisfactory outcomes. Herein, we examine the differences in presentation, pathophysiology, and treatments of typical ON causes, like multiple sclerosis (MS), and atypical causes such as neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein (MOG)-immunoglobulin G (IgG) ON. The present investigation places focus on both neuroimaging and visual imaging in the differentiation of ON. Additionally, this review presents physicians with a better understanding of different presentations, treatments, and prognoses of ON.

Investigational pharmacological agents for the treatment of ARDS

INTRODUCTION

Acute Respiratory Distress Syndrome (ARDS) is a heterogeneous form of lung injury with severe hypoxemia and bilateral infiltrates after an inciting event that results in diffuse lung inflammation with a high mortality rate. While research in COVID-related ARDS has resulted in several pharmacotherapeutic agents that have undergone successful investigation, non-COVID ARDS studies have not resulted in many widely accepted pharmacotherapeutic agents despite exhaustive research.

AREAS COVERED

The aim of this review is to discuss adjuvant pharmacotherapies targeting non-COVID Acute Lung Injury (ALI)/ARDS and novel therapeutics in COVID associated ALI/ARDS. In ARDS, variable data may support selective use of neuromuscular blocking agents, corticosteroids and neutrophil elastase inhibitors, but are not yet universally used. COVID-ALI/ARDS has data supporting the use of IL-6 monoclonal antibodies, corticosteroids, and JAK inhibitor therapy.

EXPERT OPINION

Although ALI/ARDS modifying pharmacological agents have been identified in COVID-related disease, the data in non-COVID ALI/ARDS has been less compelling. The increased use of more specific molecular phenotyping based on physiologic parameters and biomarkers, will ensure equipoise between groups, and will likely allow more precision in confirming pharmacological agent efficacy in future studies.

Does stress make males? An experiment on the role of glucocorticoids in anuran sex reversal

Environmentally sensitive sex determination may help organisms adapt to environmental change but also makes them vulnerable to anthropogenic stressors, with diverse consequences for population dynamics and evolution. The mechanisms translating environmental stimuli to sex are controversial: although several fish experiments supported the mediator role of glucocorticoid hormones, results on some reptiles challenged it. We tested this hypothesis in amphibians by investigating the effect of corticosterone on sex determination in agile frogs (Rana dalmatina). This species is liable to environmental sex reversal whereby genetic females develop into phenotypic males. After exposing tadpoles during sex determination to waterborne corticosterone, the proportion of genetic females with testes or ovotestes increased from 11% to up to 32% at 3 out of 4 concentrations. These differences were not statistically significant except for the group treated with 10 nM corticosterone, and there was no monotonous dose-effect relationship. These findings suggest that corticosterone is unlikely to mediate sex reversal in frogs. Unexpectedly, animals originating from urban habitats had higher sex-reversal and corticosterone-release rates, reduced body mass and development speed, and lower survival compared to individuals collected from woodland habitats. Thus, anthropogenic environments may affect both sex and fitness, and the underlying mechanisms may vary across ectothermic vertebrates.

Concurrent Tuberculous Optic Neuritis and Optic Perineuritis in a Patient With Human Immunodeficiency Virus (HIV)

Concurrent tuberculous optic neuritis (ON) and optic perineuritis (OPN) in a patient with human immunodeficiency virus (HIV) is extremely rare. HIV-induced progressive CD4 depletion is associated with an increased risk of tuberculosis (TB), disseminated TB, and death. Early detection and initiation of anti-TB therapy with corticosteroid commencement helps in achieving better visual outcomes. Interestingly, we report a case of concurrent ON and OPN in a patient with HIV-TB co-infection. A 29-year-old lady, a prisoner, with newly diagnosed treatment-naive HIV, presented with acute-onset reduced vision in the left eye for 10 days. It was associated with pain in eye movement and headache. The patient was known to be a drug abuser since the age of 19 years and was a sexual worker. Her CD4 count was 292 cells/mm3.Visual acuity of the right eye was 6/12 with a pinhole of 6/9, and there was no perception of light (NPL) in all four quadrants of the left eye. Relative afferent pupillary defect (RAPD) was positive in the left eye. Both anterior segments were unremarkable. The right eye fundoscopy showed a normal optic disc, while the left eye showed a hyperemic disc. During subsequent follow-up, the patient had reduced right eye vision, and the vision dropped to 6/30 with a pinhole of 6/15. Her erythrocyte sedimentation rate (ESR) was raised to 88 mm/h. The Mantoux test was positive. Chest radiography was normal. MRI of the brain and orbit showed significant enhancement of the right optic nerve and left optic nerve sheath suggesting the diagnosis of right eye ON and left eye OPN secondary to TB. The patient was co-managed with an infectious disease team. She was started on highly active antiretroviral therapy (HAART) treatment (oral Tenvir-EM and efavirenz) upon presentation. Anti-TB therapy was commenced two months later. She was started on the intensive phase of the anti-TB regime followed by the maintenance phase. Oral dexamethasone was given concurrently according to the central nervous system (CNS) TB regime for six weeks. During follow-up, her right eye visual acuity was 6/9, and her left eye visual acuity improved to 6/12. Fundoscopy showed bilateral pale discs. To date, no episodes of recurrence have been seen.

Esophageal Candidiasis-Associated Hospitalizations: Declining Rates and Changes in Underlying Conditions, United States, 2010-2020

In a nationally representative hospital discharge database, esophageal candidiasis-associated hospitalization rates per 100 000 population steadily declined from 17.0 (n = 52 698, 2010) to 12.9 (n = 42 355, 2020). During this period, a decreasing percentage of EC-associated hospitalizations involved HIV and an increasing percentage involved gastroesophageal reflux disease, diabetes, and long-term steroid use.

Non-Systemic Medication for the Treatment of Prurigo Nodularis: A Systematic Review

Prurigo nodularis (PN) is a skin disease characterized by firm, itchy, erythematous lesions. Treatment consists of systemic and non-systemic modes of therapy. Non-systemic forms of treatment are first-line and include topical corticosteroids, topical steroid-sparing agents, and phototherapy. The objective was to review the efficacy of non-systemic treatment used to treat PN. A systematic search was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered with PROSPERO (CRD42023412012). The search consisted of keywords and Medical Subject Heading (MeSH) terms and translated to Ovid MEDLINE, Embase, and Scopus. Google Scholar was also searched for the first 200 articles. Article quality of evidence was scored using GRADE criteria. The search yielded 1151 results; 37 met criteria for inclusion. There were 14 studies on phototherapy, and 11 studies on topical corticosteroids, most of which were also combined with topical antihistamines, antipruritics, and/or phototherapy. There were 2 studies each on topical antipruritics used in isolation, vitamin D analogues, and intralesional triamcinolone acetonide. There was 1 study each on topical pimecrolimus, tacrolimus, 2% dinitrochlorobenzene, cryotherapy, acupuncture, and the Paul Gerson Unna boot. Most were case reports and case series, although 2 randomized controlled trials on phototherapy and topical pimecrolimus were included. Corticosteroids had varying levels of positive response in patients and appeared more effective when used in combination or under occlusive dressing. Phototherapy is likely effective, but the risk of relapse is high. Cryotherapy may also be a lesion-directed agent to circumvent challenges to adherence and avoidance of systemic medication.

A rare clinical presentation of COVID 19: opsoclonus-myoclonus ataxia syndrome

INTRODUCTION

Coronavirus disease 2019 (COVID-19) can have symptoms like many neurological diseases, and one of the rare forms of these presentations is opsoclonus-myoclonus ataxia syndrome (OMAS). The pathogenesis of OMAS in adults has not been clearly elucidated and OMAS can be fatal.

CASE PRESENTATION

We present a 71-year-old male patient who was admitted to the emergency department with complaints of involuntary tremor-like movements in his hands, feet and mouth, and speech impediment for three days, and was followed up with COVID-19. The patient was diagnosed with OMAS and clonazepam treatment was started. He died three days later due to respiratory arrest. Our case is the first case diagnosed with COVID-19-associated OMAS in Turkey.

DISCUSSION

OMAS has no definitive treatment. Early diagnosis and initiation of corticosteroids and intravenous immunoglobulin (IVIG) therapy, if necessary, can be life-saving. In COVID-19 patients with unexplained clinical findings, awareness of different and rare diseases and a multidisciplinary approach has vital importance.

The Chitranjan S. Ranawat Award: Manipulation Under Anesthesia to Treat Postoperative Stiffness After Total Knee Arthroplasty: A Multicenter Randomized Clinical Trial

BACKGROUND

Manipulation under anesthesia (MUA) occurs in 4% of patients after total knee arthroplasty (TKA). Anti-inflammatory medications may target arthrofibrosis pathogenesis, but the data are limited. This multicenter randomized clinical trial investigated the effect of adjuvant anti-inflammatory medications with MUA and physical therapy on range of motion (ROM) and outcomes.

METHODS

There were 124 patients (124 TKAs) who developed stiffness after primary TKA for osteoarthritis enrolled across 15 institutions. All received MUA when ROM was < 90° at 4 to 12 weeks postoperatively. Randomization proceeded via a permuted block design. Controls received MUA and physical therapy, while the treatment group also received one dose of pre-MUA intravenous dexamethasone (8 mg) and 14 days of oral celecoxib (200 mg). The ROM and clinical outcomes were assessed at 6 weeks and 1 year. This trial was registered with ClinicalTrials.gov.

RESULTS

The ROM significantly improved a mean of 46° from a pre-MUA ROM of 72 to 118° immediately after MUA (P < .001). The ROM was similar between the treatment and control groups at 6 weeks following MUA (101 versus 99°, respectively; P = .35) and at one year following MUA (108 versus 108°, respectively; P = .98). Clinical outcomes were similar at both end points.

CONCLUSIONS

In this multicenter randomized clinical trial, the addition of intravenous dexamethasone and a short course of oral celecoxib after MUA did not improve ROM or outcomes. However, MUA provided a mean ROM improvement of 46° immediately, 28° at 6 weeks, and 37° at 1 year. Further investigation in regards to dosing, duration, and route of administration of anti-inflammatory medications remains warranted.

Chronic Inflammatory Demyelinating Polyradiculoneuropathy: Current Therapeutic Approaches and Future Outlooks

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a treatable autoimmune disorder, for which different treatment options are available. Current first-line evidence-based therapies for CIDP include intravenous and subcutaneous immunoglobulins, corticosteroids and plasma exchanges. Despite lack of evidence, cyclophosphamide, rituximab and mycophenolate mofetil are commonly used in circumstances of refractoriness and, more debatably, of perceived overdependence on first-line therapies. Rituximab is currently the object of a randomized controlled trial for CIDP. Based on case series, and although rarely considered, haematopoietic autologous stem cell transplants may be effective in refractory disease, with low mortality and high remission rates. A new therapeutic option has appeared with efgartigimod, a neonatal Fc receptor blocker, recently shown to significantly lower relapse rate versus placebo, after withdrawal from previous immunotherapy. Other neonatal Fc receptor blockers, nipocalimab and batoclimab, are under study. The C1 complement-inhibitor SAR445088, acting in the proximal portion of the classical complement system, is currently the subject of a new study in treatment-responsive, refractory and treatment-naïve subjects. Finally, Bruton Tyrosine Kinase inhibitors, which exert anti-B cell effects, may represent another future research avenue. The widening of the therapeutic armamentarium enhances the need for improved evaluation of treatment effects and reliable biomarkers in CIDP.

Development and Comparison of Treatment Decision Tools for Glucocorticoid-Induced Osteoporosis

Long-term Glucocorticoid (GC) use results in compromised bone strength and fractures, and several treatment recommendations have been developed to prevent fractures, but none have been validated in a real-world setting. This study aims to create a treatment decision tool and compares this tool to the treatment suggestions from the American College of Rheumatology (ACR), International Osteoporosis Foundation and European Calcified Tissue Society (IOF-ECTS), and GC-adjusted Fracture Risk Assessment Tool (GC-FRAX), above the intervention threshold. We utilized registry data gathered at Chang Gung Memorial Hospital at Kaohsiung, Taiwan, between September 2014 and April 2021. This research is a single-center, observational, and case-controlled study. We recruited participants using prednisone for at least 2.5 mg/day or the equivalent dose for over 3 months, excluding those younger than 40, those with malignancies, or those currently undergoing anti-osteoporosis therapy. The primary endpoint was new fragility fractures within 3 years, including morphometric vertebral fractures detected at baseline and with a follow-up thoracic-lumbar spine X-ray. Participants were randomly allocated into derivation and validation sets. We developed the Steroid-Associated Fracture Evaluation (SAFE) tool in the derivation cohort by assessing the weights of exploratory variables via logistic regression. Prediction performance was compared in the validation set by the receiver operating characteristic (ROC) curve, the area under the curve (AUC), and sensitivity and specificity. A total of 424 treatment-naïve subjects were enrolled, and 83 (19.6%) experienced new fractures within 3 years. The final formula of the SAFE tool includes osteoporosis (1 point), an accumulated GC dose ≥ 750 mg within 6 months (or equivalent prednisolone of ≥4.5 mg/day for 6 months) (1 point), a BMI ≥ 23.5 (1 point), previous fractures (1 point), and elderliness of ≥70 years (2 points). In the validation set, a treatment decision based on the SAFE ≥ 2 points demonstrated an AUC of 0.65, with a sensitivity/specificity/accuracy of 75.9/54.0/58.9, with an ACR of 0.56 (100.0/11.0/31.0), IOF-ECTS 0.61 (75.9/46.0/52.7), and GC-FRAX 0.62 (82.8/42.0/51.2). Among current GIOP recommendations, the SAFE score serves as an appropriate treatment decision tool with increased accuracy and specificity.

Lactoferrin in the Prevention of Recurrent Respiratory Infections in Preschool Children: A Prospective Randomized Study

Few studies have evaluated the effect of bovine lactoferrin (bLf) on reducing respiratory infections in preschool children. This randomized controlled trial evaluated the effect of bLf in preschool children with recurrent respiratory infections. Participants were randomly assigned bLf (n = 25) or control (n = 25). Outcomes included respiratory infection episodes (RIEs), symptom duration, school absence and medication. Fifty children aged 4.2 ± 0.1 years were included. During the active 4-month phase, median number of RIEs was reduced by 50% in the bLf group [1-episode, interquartile range (IQR): 0-2] vs. control (2, IQR: 1-3; p = 0.02). The proportion of participants with >3 RIEs was significantly lower in bLf (n = 1, 4%) vs. control (n = 7, 28%) with 80% lower odds of upper RIEs in the bLf arm (odds ratio: 0.20, 95% CI:0.06-0.74, p = 0.015). The duration of symptoms (3 vs. 6, p = 0.009) and days absent from school (3 vs. 6, p = 0.15) were lower in the active arm. Over the 2-month follow-up, no significant differences were observed between groups for infection episodes, symptom duration or school absence. However, bLf-treated children received significantly less corticosteroids over the entire 6-month study period (32% vs. 60%; p = 0.047). bLf supplementation significantly reduced the frequency and duration of RIEs in children with decreased corticosteroid use.

Unveiling Ocular Manifestations in Systemic Lupus Erythematosus

Systemic Lupus Erythematosus (SLE) is a complex autoimmune disorder characterized by immune dysregulation and multi-organ involvement. In this concise brief review, we highlight key insights into Ocular Systemic Lupus Erythematosus (SLE), an intricate autoimmune disorder with diverse organ involvement. Emphasizing the formation of autoantibodies and immune complex deposition, we delve into the inflammation and damage affecting ocular structures. Clinical presentations, ranging from mild dry eye syndrome to severe conditions like retinal vasculitis, necessitate a comprehensive diagnostic approach, including clinical exams, serological testing, and imaging studies. Differential diagnosis involves distinguishing SLE-related ocular manifestations from other autoimmune and non-inflammatory ocular conditions. The multidisciplinary management approach, involving rheumatologists, ophthalmologists, and immunologists, tailors treatment based on ocular involvement severity, encompassing corticosteroids, immunosuppressive agents, and biologics. Follow-up is crucial for monitoring disease progression and treatment response. Future perspectives revolve around advancing molecular understanding, refining diagnostic tools, and exploring targeted therapies. Novel research areas include genetic factors, microbiome composition, and biotechnology for tailored and effective SLE ocular treatments.

Emergency management and asthma risk in young Medicaid-enrolled children with recurrent wheeze

OBJECTIVES

To describe clinical characteristics of young children presenting to the emergency department (ED) for early recurrent wheeze, and determine factors associated with subsequent persistent wheeze and risk for early childhood asthma.

METHODS

Retrospective cohort study of Medicaid-enrolled children 0-3 years old with an index ED visit for wheeze (e.g. bronchiolitis, reactive airway disease) from 2009 to 2013, and at least one prior documented episode of wheeze at an ED or primary care visit. The primary outcome was persistent wheeze between 4 and 6 years of age. Demographics and clinical characteristics were collected from the index ED visit. Logistic regression was used to estimate the association between potential risk factors and subsequent persistent wheeze.

RESULTS

During the study period, 41,710 children presented to the ED for recurrent wheeze. Mean age was 1.3 years; 59% were male, 42% Black, and 6% Hispanic. At index ED visits, the most common diagnosis was acute bronchiolitis (40%); 77% of children received an oral corticosteroid prescription. Between 4 and 6 years of age, 11,708 (28%) children had persistent wheeze. A greater number of wheezing episodes was associated with an increased odds of ED treatment with asthma medications. Subsequent persistent wheeze was associated with male sex, Black race, atopy, prescription for bronchodilators or corticosteroids, and greater number of visits for wheeze.

CONCLUSIONS

Young children with persistent wheeze are at risk for childhood asthma. Thus, identification of risk factors associated with persistent wheeze in young children with recurrent wheeze might aid in early detection of asthma and initiation of preventative therapies.

Real-World Utilization of Corticosteroids in Severe Alcoholic Hepatitis: Eligibility, Response, and Outcomes

Background and Objectives: Alcoholic hepatitis (AH) poses a medical challenge, causing moderately severe to life-threatening episodes with high short- and long-term mortality. This study aimed to explore real-world corticosteroid utilization in severe AH, response predictors, and patient outcomes. Materials and Methods: We conducted a retrospective study on patients admitted for severe AH, defined as a Maddrey Discriminant Function score equal to or above 32, at a tertiary care center. We reviewed patients' medical observation charts to identify corticosteroid prescriptions, reasons for ineligibility, and response rates. Responders were defined based on the Lille score, and predictors of non-response were identified. Short-term (one-month) and long-term (one-year) mortality rates were calculated according to treatment and response. Results: Out of 310 patients enrolled with severe AH, 59% received corticosteroids, achieving a response rate of 75.4%. The reasons for not administering corticosteroids were as follows: uncontrolled infections (27.6%), renal dysfunction (20.4%), gastrointestinal bleeding (18.9%), acute pancreatitis (7.1%), uncontrolled diabetes (3.1%), and other or unknown causes (22.8%). The overall 1-month mortality rate was 12.2%, higher in non-responders (35.3%) and patients who did not receive corticosteroids (13.4%) compared to responders (3.6%). The overall 1-year mortality rate was 62.5%, similar between patients who did not receive corticosteroids (78.7%) and non-responders (77.7%) and higher compared to responders (42.8%). Predictive factors for non-response included older age (OR = 1.05, 95%CI: 1.01-1.08), concomitant cirrhosis (OR= 2.11, 95% CI: 1.064-4.20), MELD scores exceeding 30 (OR = 2.42, 95% CI: 1.21-4.80), severe hypoalbuminemia (OR = 2.46, 95%CI: 1.12-5.37), and increased serum creatinine (OR = 1.5, 95% CI: 1.1-2.03). Among the prognostic scores, MELD 3.0 score exhibited superior efficacy for short-term (AUC = 0.734, 95% CI 0.656-0.811) and long-term mortality (AUC = 0.777, 95% CI: 0.724-0.830) compared to alternative scoring systems. Conclusions: Low eligibility rate and poor prognosis underscore the need for effective therapies. Our findings contribute to refining risk stratification and early prediction of non-response, aiding clinicians in identifying more beneficial therapies.

Acute macular neuroretinopathy and COVID-19 or SARS-CoV-2 infection: case report and literature review

Purpose

To describe a case of acute macular neuroretinopathy (AMN) associated with COVID-19 infection and a related literature review.

Methods

A case from the First Affiliated Hospital of Chongqing Medical University was reported that could be linked to COVID-19 or SARS-CoV-2 infection. We performed a comprehensive search on PubMed, retrieving articles containing information on AMN after COVID-19 or SARS-CoV-2 infection. The key words used were 'COVID-19', 'SARS-CoV-2', 'ophthalmic manifestations', 'acute macular neuroretinopathy', and 'paracentral scotomas'. The relevant data were extracted, charted, consolidated, and evaluated. Moreover, manual exploration of the reference lists of pertinent articles was carried out.

Results

We describe the case of a 30-year-old young woman who developed bilateral AMN one day after being infected with COVID-19 or SARS-CoV-2. She had severe visual impairment (20/2000 OD and 20/32 OS), and her vision recovered after taking oral corticosteroids. After reviewing the literature, we summarized 16 relevant reports and found that symptoms of AMN tend to arise 1 day to 1 month after COVID-19 or SARS-CoV-2 infection. Contraceptive pills and other risk factors should be avoided to reduce the risk of adverse outcomes. Oral prednisone may be an effective treatment for those experiencing important vision loss.

Conclusion

Symptoms of AMN can arise 1 day to 1 month after COVID-19 or SARS-CoV-2 infection. Ophthalmologists should remain vigilant about this disease, notably because patient characteristics may deviate from the norm.

The Short-Term Outcome of Transforaminal Epidural Steroid Injection in Patients with Radicular Pain Due to Foraminal Stenosis from Lumbar Isthmic Spondylolisthesis

Purpose

In this study, we evaluated the therapeutic outcomes of transforaminal epidural steroid injection (TFESI) in managing chronic radicular pain due to foraminal stenosis. Furthermore, we evaluated its effectiveness according to isthmic spondylolisthesis (IS) severity.

Patients and Methods

We included 40 patients with radicular pain due to IS-derived foraminal stenosis in our study and treated them with TFESI. Two patients were lost during follow-up. Based on the lateral lumbar radiograph findings, we allocated the recruited patients with < 25% slippage by IS to Group 1 (n = 23) and those having 25-50% slippage to Group 2 (n = 15). The degree of pain was measured using a numeric rating scale (NRS) at pre-treatment and 1 and 2 months after TFESI.

Results

In 38 patients who completed the study, the NRS at pre-treatment was significantly reduced at the 1- and 2-month follow-ups. In the Group analysis, the NRS scores were significantly reduced after TFESI in both Groups 1 and 2, regardless of IS severity. However, the reduction in NRS scores 1 month after TFESI was significantly greater in Group 1 than in Group 2. Moreover, the rate of successful treatment outcomes was significantly higher (65.2%) in Group 1 than in Group 2 (26.7%).

Conclusion

After TFESI, chronic radicular pain was significantly reduced regardless of IS severity, and its effect persisted for at least 2 months. However, its effect was superior when the vertebra slippage by IS was less than 25% compared to patients with 25%-50%.
