Immunosuppressants in women with repeated implantation failure in assisted reproductive techniques: a systematic review and meta-analysis.

Objective: To compare outcomes in patients with repeated implantation failure undergoing Intracytoplasmic Sperm Injection/In vitro fertilization (IVF/ICSI) plus immunosuppressants such as prednisolone, prednisone, or cyclosporine A versus the use of IVF/ICSI alone. Data source: Databases were systematically searched in PubMed, Cochrane, and Embase databases in September 2023. Study Selection: Randomized clinical trials and observational studies with the outcomes of interest were included. Data collect: We computed odds ratios (ORs) for binary endpoints, with 95% confidence intervals (CIs). Heterogeneity was assessed using I2 statistics. Data were analyzed using Review Manager 5.4.The main outcomes were live birth, miscarriage, implantation rate, clinical pregnancy, and biochemical pregnancy. Data synthesis: Seven studies with 2,829 patients were included. Immunosuppressive treatments were used in 1,312 (46.37%). Cyclosporine A improved implantation rate (OR 1.48; 95% CI 1.01-2.18) and clinical pregnancy (1.89, 95% CI 1.14-3.14). Compared to non-immunosuppressive treatment, prednisolone and prednisone did not improve live birth (OR 1.13, 95% CI 0.88-1.46) and miscarriage (OR 1.49, 95% CI 1.07-2.09). Prednisolone showed no significant effect in patients undergoing IVF/ICSI, clinical pregnancy (OR 1.34; 95% CI 0.76-2.36), or implantation rate (OR 1.36; 95% CI 0.76-2.42). Conclusion: Cyclosporine A may promote implantation and clinical pregnancy rates. However, given the limited sample size, it is important to approach these findings with caution. Our results indicate that prednisolone and prednisone do not have any beneficial effects on clinical outcomes of IVF/ICSI patients with repeated implantation failure. PROSPERO: CRD42023449655.

Linear IgA bullous dermatosis in a latin adolescent treated with cyclosporine and prednisone.

INTRODUCTION: Linear IgA bullous dermatosis (LABD) is a rare autoimmune disease. Although dapsone is the initial treatment, other immunomodulators are used in resistant cases or when dapsone is unavailable. CASE REPORT: A 12-year-old Mexican child, with no relevant medical history, developed in May 2023 a disseminated dermatosis affecting all body segments, including mucous membranes, characterized by erythematous patches and plaques evolving into the formation of serous and serosanguinous blisters and vesicles, distributed in a "string of pearls" pattern. LABD was suspected and confirmed by skin biopsy, which showed a subepidermal blister with neutrophilic infiltration and linear Immunoglobulin A deposits at the dermo-epidermal junction by direct immunofluorescence. Treatment with prednisone (2 mg/kg/day) and cyclosporine (5 mg/kg/day) resulted in improvement and lesion remission within 2 weeks. Both drugs needed to be discontinued for 3 months due to intermittent blistering. Cyclosporine was continued as maintenance therapy at a dose of 4 mg/kg/day for 8 months. CONCLUSIONS: The report highlights the use of cyclosporine as an alternative immunomodulator for DAAL, an immunosuppressive agent used in autoimmune disorders. Few cases, including this one, have described complete remission and control of the dermatosis with cyclosporine, accompanied by prednisone at the start of treatment.

INTRODUCCIÓN: La dermatosis ampollosa por IgA lineal es una enfermedad autoinmunitaria rara. Aunque la dapsona es el tratamiento inicial, se usan otros inmunomoduladores en casos resistentes o cuando la dapsona no está disponible. CASO CLÍNICO: Un niño mexicano de 12 años, sin antecedentes relevantes, desarrolló en mayo de 2023 una dermatosis diseminada a todos los segmentos corporales, incluyendo las mucosas, caracterizada por manchas y placas eritematosas que evolucionaron hacia la formación de ampollas y vesículas serosas y serohemáticas, distribuidas en forma de «cadena de perlas¼. Se sospechó dermatosis ampollosa por IgA lineal y se confirmó mediante biopsia cutánea, que mostró una ampolla subepidérmica con infiltrado neutrófilo y depósitos lineales de IgA en la unión dermoepidérmica mediante inmunofluorescencia directa. El tratamiento con prednisona (2 mg/kg al día) y ciclosporina (5 mg/kg al día) resultó en mejoría y la remisión de las lesiones a las 2 semanas. Fue necesario dejar ambos fármacos durante 3 meses debido a la aparición intermitente de ampollas. Se dejó ciclosporina como terapia de mantenimiento a dosis de 4 mg/kg al día por 8 meses. CONCLUSIONES: El reporte destaca el uso de ciclosporina como inmunomodulador alternativo para la dermatosis ampollosa por IgA lineal, un agente inmunosupresor utilizado en trastornos autoinmunitarios. Pocos casos, incluido este, han descrito la remisión completa y el control de la dermatosis con ciclosporina, acompañada de prednisona al inicio del tratamiento.

Intravenous methylprednisolone for nephrotic syndrome with minimal change lesions in adults: a randomized controlled trial.

BACKGROUND AND HYPOTHESIS: Patients with minimal change nephrotic syndrome (MCNS) usually experienced severe edema which can affect the absorption of oral corticosteroid during the first 2 weeks. We conducted a randomized controlled trial to compare the efficacy of intravenous isovalent methylprednisolone induction followed by oral prednisone therapy with conventional oral prednisone therapy in highly edematous MCNS patients, aiming to provide a better therapy for MCNS patients. METHODS: A single-center, open-label, parallel-arm randomized controlled trial was performed in the Nephrology Department of the Affiliated Hospital of Guangdong Medical University. Patients who met the inclusion were enrolled in our study from May 2015 to October 2020, and were randomized to receive conventional oral steroid or 2 weeks intravenous methylprednisolone followed by oral prednisone. RESULTS: 117 patients were enrolled and randomly assigned to either the sequential group (N = 57) or the oral group (N = 60). Total remission rate in the sequential group was higher than the oral group after treatment for 2 weeks and 4 weeks (P = 0.032, P = 0.027). Complete remission rate was higher in the sequential group than in the oral group (63.3% vs. 41.5%, P = 0.031) after treatment for 2 weeks. The time to achieve CR is shorter in the sequential group than the oral group, with a statistically significant difference (14.0 days, 95% CI [13.5 to 14.5] vs. 16.0 days, 95% CI [12.7 to 19.3], P = 0.024). There were no significant difference in relapse rate (24.5% vs 28.3%, P = 0.823) and time to relapse (155 ± 103 days vs 150.7 ± 103.7 days, P = 0.916) between two groups. CONCLUSION: This study suggested that highly edematous MCNS patients received intravenously isovalent methylprednisolone induction therapy follow by oral prednisone achieved earlier remission than the conventional oral prednisone regimen without differences in relapse rates or adverse effects. Short-term intravenous methylprednisolone followed by oral prednisone may be a better choice for MCNS patients with highly edema.

Steroid-Dependent Recurrent IgA Vasculitis in a 19-Year-Old Woman.

Background: Immunoglobulin A (IgA) vasculitis is common in children and typically resolves spontaneously. However, when presenting in adults, it is more likely to be severe and recurrent. Case Presentation: We present the case of a 19-year-old female patient with recurrent steroid-dependent IgA vasculitis. She had a history of a prolonged episode of IgA vasculitis in childhood. She presented to our hospital with proteinuria and a painful, palpable purpuric rash on her bilateral lower extremities. She was treated with high-dose intravenous steroids. When steroids were tapered, the patient had a recurrence of her painful rash. Over several months, she developed steroid-induced hyperglycemia and worsening proteinuria. Conclusion: Recent studies have shown that corticosteroids have limited effect on long-term outcomes in IgA vasculitis, but steroid-sparing agents have potential for the treatment of recurrent steroid-dependent IgA vasculitis.

Case report: A case of effective treatment of primary myelofibrosis with nodular panniculitis using ruxolitinib combined with corticosteroids.

We report the case of a 54-year-old healthy Han Chinese male presenting with fever, pallor, erythematous subcutaneous nodules on the limbs, and significant anemia as indicated by routine blood tests, with no response to antimicrobial therapy. Initial skin biopsy was inconclusive. The erythematous subcutaneous nodules on the limbs rapidly progressed to widespread subcutaneous nodules across the body, with worsening anemia. Bone marrow biopsy revealed multifocal fibroblastic proliferation with focal fibrosis, classified as MF-2, and positive for the JAK2V617F mutation alongside SRSF2 positivity. Whole-body PET-CT scans did not reveal any lymph nodes or suspect lesions with high SUV uptake. A subsequent skin biopsy identified the condition as nodular panniculitis (NP), leading to a final diagnosis of primary myelofibrosis(PMF)with NP. The patient initially received treatment with oral ruxolitinib and prednisone acetate, resulting in normalization of body temperature, resolution of erythematous nodules, and normalization of blood parameters.

Efficacy and safety of different doses of vamorolone in boys with Duchenne muscular dystrophy: a systematic review and network meta-analysis.

Background and objectives: Several recent clinical studies have indicated that vamorolone is comparable in effectiveness to glucocorticosteroids for treating Duchenne muscular dystrophy (DMD). However, there is a lack of extensive data regarding the efficacy and safety of various doses of vamorolone. We conducted a study to evaluate the efficacy of different doses of vamorolone in boys with DMD, and compare the safety of vamorolone vs. glucocorticosteroids, prednisone or deflazacort in boys with DMD. Methods: We performed systematic searches of the PubMed, Embase, and Cochrane Library databases for vamorolone, glucocorticosteroids, prednisone or deflazacort in boys with DMD. We assessed statistical heterogeneity across trials based on the Newcastle Ottawa scale (NOS) tool test and I2 values, and mean differences were pooled using the random-effects model. We used traditional meta-analysis to evaluate efficacy and safety of vamorolone 6.0 mg/kg/d vs. vamorolone 2.0 mg/kg/d and vamorolone vs. prednisone. A network meta-analysis was applied to estimated the safety of vamorolone in comparison to glucocorticosteroids, prednisone and deflazacort. Our meta-analysis were performed using Revman 5.4 software, and our network meta-analysis were performed using Stata/MP 18.0. Results: In the meta-analysis, a total of 193 patients were analyzed across four clinical trials (97 patients receiving vamorolone 2 mg/kg per day; 96 patients receiving vamorolone 2 mg/kg per day). We observed that there were statistically significant differences in boys with DMD between vamorolone 6.0 mg/kg/d and vamorolone 2.0 mg/kg/d in TTSTANDV (MD = 0.03, 95%CI = 0.00-0.06, p = 0.04), TTRWV (MD = 0.13, 95%CI = 0.08-0.19, p < 0.01), 6MWT (MD = 24.54, 95%CI = 4.46-44.82, p = 0.02), TTCLIMBV (MD = 0.04, 95%CI = 0.01-0.06, p = 0.009), no significant difference in BMI z score (MD = 0.09, 95%CI = -0.03-0.20, p = 0.13). Indirect comparisons derived from network meta-analysis did not show significant differences among vamorolone, glucocorticosteroids, prednisone and deflazacort in BMI z score. Conclusion: Our findings implied that boys with DMD who took vamorolone 6 mg/kg daily instead of 2 mg/kg daily may be safer and have superior motor function. However, more large sample randomized controlled trials are needed to confirm our results. Systematic Review Registration: This systematic review and meta-analysis has been registered in the International Prospective Register of Ongoing Systematic Reviews PROSPERO (registration number: CRD42024562916).

Eosinophilic ascites and enteritis: a neglected case report from Vietnam.

Eosinophilic gastroenteritis poses a significant diagnostic challenge, particularly in developing countries, where the awareness of this condition may be limited. Here, the case of a patient in her early 30s, who presented with recurrent episodes of abdominal pain and diarrhea, is reported. Initial standard laboratory investigations revealed normal complete blood counts and elevated total serum immunoglobulin E levels. Upper and lower endoscopic evaluations with systemic biopsies did not reveal any significant abnormalities. However, computed tomography revealed a thickened small intestine wall, halo signs, and mild ascites. Analysis of the ascitic fluid confirmed eosinophilia. These findings prompted a diagnosis of eosinophilic gastroenteritis. The patient responded well to a targeted elimination diet, corticosteroids, and antileukotriene medication. The present case emphasizes the importance of considering eosinophilic gastroenteritis in the differential diagnosis of patients who present with abdominal pain and eosinophilic ascites.

Patient-reported Outcomes for Patients with Metastatic Castration-resistant Prostate Cancer and BRCA1/2 Gene Alterations: Final Analysis from the Randomized Phase 3 MAGNITUDE Trial.

BACKGROUND AND OBJECTIVE: The phase 3 MAGNITUDE trial assessed the efficacy and safety of niraparib 200 mg and abiraterone acetate 1000 mg plus prednisone 10 mg (AAP) in patients with metastatic castration-resistant prostate cancer (mCRPC) and alterations in homologous recombination repair (HRR) genes. Here we report final analysis results for patient-reported outcomes (PROs) in the HRR+ cohort with a focus on BRCA1/2 alterations (BRCA+). METHODS: Protocol-specified endpoints evaluated patient-reported symptoms, health-related quality of life (HRQoL), and tolerability (side-effect bother) using the Brief Pain Inventory-Short Form (BPI-SF), Functional Assessment of Cancer Therapy-Prostate (FACT-P), and EQ-5D-5L questionnaires. Evaluations were completed on day 1 of designated treatment cycles and during follow-up. KEY FINDINGS AND LIMITATIONS: All patients with BRCA+ mCRPC (n = 225) were included in the PRO analyses with average on-treatment PRO compliance >80% when completed on-site. Time to deterioration in pain according to BPI-SF and FACT-P scores did not significantly differ between niraparib + AAP and placebo + AAP. During treatment, EQ-5D-5L revealed no clinically meaningful differences in overall HRQoL between treatment arms in the BRCA+ subgroup. Finally, tolerability was similar between arms; side effect bother rated as "not at all" or "a little bit" ranged from 79.8% to 95.9% during treatment. Limitations include a sample size that may not have been powered to detect a difference in PROs. CONCLUSIONS AND CLINICAL IMPLICATIONS: Treatment with niraparib + AAP maintained HRQoL with minimal side-effect bother reported by most patients with BRCA+ mCRPC. Differences between treatment groups in time to pain deterioration did not meet conventional levels of statistical significance. The MAGNITUDE trial is registered on ClinicalTrials.gov as NCT03748641.

Efficacy and safety of different oral prednisone tapering courses in adult anti-NMDAR encephalitis: A multicenter prospective cohort study.

OBJECTIVE: In adult anti-N-methyl-d-aspartate receptor (NMDAR) encephalitis, corticosteroids are commonly used as first-line treatment. However, the optimal oral prednisone tapering (OPT) following intravenous methylprednisolone pulse therapy remains unclear. We aim to compare the efficacy and safety of different OPT courses in anti-NMDAR encephalitis. METHODS: The CHASE study, a multicenter prospective observational cohort study, enrolled patients with autoimmune encephalitis from October 2011 to March 2023. Patients were grouped based on oral prednisone tapering course: ≤3 months (Group ≤3 month), 3-6 months (Group 3-6 months, including 3 months), and >6 months (Group > 6 months). Kaplan-Meier plots were used to analyze time to relapse and time to total recovery within 2 years. RESULTS: Among 666 screened patients, 171 (median [IQR] age 27 [21.0-36.5] years, 55.0% female) met selection criteria. Responders at 3 months were prevalent in Group ≤3 months (OR 7.251 [95% CI 2.252 to 23.344] and Group 3-6 months (OR, 3.857 [95% CI 1.107 to 13.440] than in Group >6 months. Clinical Assessment Scale for Autoimmune Encephalitis (CASE) scores at 12 months were higher in Group >6 months than in Group ≤3 months and Group 3-6 months (ß, -2.329 [95% CI -3.784 to -.875]; ß, -2.871 [95% CI -4.490, -1.253]). CASE seizures subscore was higher in Group >6 months than in Group 3-6 months (ß, -.452 [95% CI -.788 to -.116]). No significant difference in seizure freedom rates among the groups. Adverse events were higher in Group 3-6 months and Group >6 months than in Group ≤3 months (OR 6.045 [95% CI 2.352 to 15.538]; OR 6.782 [95% CI 1.911 to 24.073]). SIGNIFICANCE: Longer oral prednisone courses for adult patients with anti-NMDAR encephalitis did not show superior effects compared to shorter courses in improving modified Rankin Scale (mRS) scores and CASE scores, reducing the risk of relapse within 2 years, or achieving seizure freedom. Instead, extended prednisone courses may lead to more side effects- particularly weight gain. This outcome recommends evaluating the possibility of shortening the duration of oral prednisone after a thorough patient assessment.

Comparison of Adverse Events Following Immunosuppressant Administration for Pediatric Patients With Renal Transplants Categorized by Two-Year Age Increments Using the U.S. Food and Drug Administration Adverse Event Reporting System.

Background Immunosuppressants are frequently administered to prevent transplant rejection in patients with renal transplants but cause various adverse events. The incidence of each adverse event may differ between pediatric and adult patients with renal transplants. Because the development of organs and bodies in pediatric patients varies greatly annually, the incidence of each adverse event following immunosuppressant administration may vary by age. Consequently, the age-specific incidence of each adverse event in pediatric patients represents invaluable information for clinical settings. To clarify trends in the occurrence of adverse events by age, a large sample size for each age is required. However, it is difficult to conduct clinical trials in pediatric patients with renal transplants with a large sample size for each age. One method to address this difficulty is to use a database.  Objectives This study aimed to investigate the trends in the occurrence of each adverse event following immunosuppressant administration in pediatric patients with renal transplants, categorized by two-year age increments. Methods We extracted data on pediatric patients aged 0-17 years who received immunosuppressants after renal transplant between January 2004 and March 2024 from the U.S. Food and Drug Administration Adverse Event Reporting System. Because adverse events were greatly affected by age, the patients were divided into groups by two-year age increments. We analyzed the relationship between the groups and the reporting proportion of each adverse event by using the reporting regression coefficient (RRC) from univariate regression analysis and the adjusted RRC (aRRC), which controlled for differences in patient background. Results Renal tubular necrosis, renal impairment, chronic allograft nephropathy, and headache were the adverse events that required more attention with increasing age because RRC and aRRC were significantly > 0. By contrast, Epstein-Barr virus infection was the adverse event that required attention, especially in younger pediatric patients, because RRC and aRRC were significantly < 0. Additionally, there were various trends among other adverse events, including those that required careful monitoring across all ages 0-17 years. Conclusions This study demonstrated that the types of adverse events requiring attention in pediatric patients with renal transplants differ by age. These findings can help enhance treatment and care in pediatric clinical settings.

Use of Glucocorticoids in SLE: A Clinical Approach.

Glucocorticoids (GCs) are one of the most effective first-line treatments for systemic lupus erythematosus (SLE). However, GC burden is associated with damage. The initial GC dose and tapering schedule should be tailored to the severity of the clinical scenario. As lupus therapy should prompt remission while minimising damage, recent guidelines recommend a more accurate approach to the use of GCs, setting lower starting doses and rapid tapering schemes, and encouraging maintenance prednisolone doses <5 mg/day. Methylprednisolone pulses (MP) help to reduce the dose of oral GCs and improve the clinical response in both severe and non-severe manifestations, without significant side effects. Fixed-tapering GC scheme provides a useful strategy to reduce GCs exposure. Long-term antimalarial treatment and early initiation of immunosuppressive drugs improve clinical efficacy while reducing GC toxicity. Besides, withdrawal of GCs is an achievable goal in patients in prolonged remission on stable treatment, and recent studies have attempted to identify the most suitable candidates. In this article, we review the pharmacological basis, clinical evidence of efficacy, dose-related harms, and potential withdrawal of GCs. We also review guidelines recommendations and finally give a personal and practical approach to dealing with the use of GCs in SLE patients.

From pre-clinical efficacy to promising clinical trials that delay Type 1 diabetes.

Recent advancements in immunology and islet biology have unveiled remarkable prospects for the postponement of Type 1 diabetes (T1D) through the strategic modulation of the immune system. In this Perspective, we discuss the pharmaceutical strides achieved, traversing from pre-clinical validation to the execution of impactful clinical trials. We begin with the initial investigations involving cyclosporine and glucocorticoids in rodent models, such as the non-obese diabetic (NOD) mouse, which guided early clinical trials. We then discuss the pre-clinical studies using suitable mouse models that eventually led to contemporary clinical trials targeting immune cell functionality and cytokine signaling pathways. Collectively, these discoveries promote the exciting paradigm of immune system modulation to mitigate autoimmunity, which continues to broaden. Notably, the use of baricitinib, a potent JAK1/2 inhibitor, and teplizumab, an anti-CD3 monoclonal antibody, represent discrete methodologies converging upon a singular outcome: the preservation of islet beta-cell functionality. The latter interventional strategies build on the original idea that tempering specific facets of the immune system will generate therapeutic benefit. Enthusiasm from these discoveries stems from efficacy with reduced side effects when compared with past approaches. The success of therapeutic intervention(s) in pre-clinical studies, combined with knowledge about stages of progression to clinical T1D, have ultimately encouraged the design of more successful clinical trials targeting highly specific populations at risk. Collectively, these findings instill a profound sense of optimism, suggesting that the prevention and even reversal of T1D may soon be within reach.

Corticosteroids for the treatment of Duchenne muscular dystrophy: a safety review.

INTRODUCTION: Duchenne muscular dystrophy (DMD) is an X-linked genetic disorder characterized by progressive muscle degeneration and weakness, caused by mutations in the dystrophin gene. DMD has effects in early age with significantly shortened lifespan and deteriorated quality of life in the second decade, creating an urgent need to develop better therapeutic options. Corticosteroid medication therapy is an integral tool for the management of DMD and several therapeutic options have been recently approved for use. AREAS COVERED: A comprehensive literature search was completed to examine efficacy and safety profiles of the three corticosteroid medications available for use in DMD patients. The review presents information about the three agents through clinical trials, significant preclinical trials, and comparative studies. EXPERT OPINION: Managing DMD takes a multidisciplinary approach, although long-term corticosteroid therapy remains a significant therapeutic tool. Based on the available published studies, unequivocal comparison between the benefits of the three medications cannot yet be made. When selecting a medication for a patient, the decision-making process will most likely rely on the minor differences in the adverse effect profiles. Whichever medication is utilized will surely be a part of a larger regimen that includes other novel therapeutic agents.

Immune thrombocytopenia and pregnancy: challenges and opportunities in diagnosis and management.

INTRODUCTION: Immune thrombocytopenia (ITP) affecting pregnancy is a diagnostic and often a therapeutic challenge. AREAS COVERED: We review the current diagnostic criteria for ITP in pregnancy and the potential utility of laboratory tests. We discuss the impact of ITP on pregnancy outcomes and the effects of pregnancy on patients living with chronic ITP.  We describe the criteria for intervention, the evidence supporting first-line treatment approaches and the therapeutic decisions and challenges in cases refractory to steroids and IVIG. We review the evidence supporting the potential use of thrombopoietin receptor agonists for refractory thrombocytopenia. Finally, we describe the diagnostic, prognostic, and treatment approaches to neonatal ITP and considerations regarding breastfeeding. We searched the terms 'immune thrombocytopenia' and 'pregnancy' on PubMed to identify the relevant literature published before 31 December 2023, including within cited references. EXPERT OPINION: Decreased platelet production may play a role in pregnancy-related ITP exacerbation. Putative mechanisms include placental hormones, such as inhibin. Although IVIG and prednisone usually suffice to achieve hemostasis for delivery, second-line agents are sometimes required to allow for neuraxial anesthesia. There is growing evidence supporting the use of romiplostim during pregnancy; however, its risk of venous thromboembolism warrants further evaluation.

Adrenal suppression from vamorolone and prednisone in Duchenne muscular dystrophy: results from the phase 2b clinical trial.

CONTEXT: Vamorolone, a novel "dissociative" steroid, demonstrated similar efficacy in muscle function relative to prednisone 0.75 mg/kg/day but improved linear growth and bone turnover markers in a randomized trial of pediatric Duchenne muscular dystrophy (DMD). OBJECTIVES: To determine the frequency of adrenal suppression (AS) induced by vamorolone and prednisone in pediatric DMD, and to assess cortisol thresholds using a monoclonal antibody immunoassay. METHODS: Post-hoc analysis of cortisol levels was performed on data from a randomized, double-blind, placebo- and prednisone-controlled 24-week trial of vamorolone with a 24-week crossover extension. Morning and ACTH-stimulated cortisol levels were measured using the Elecsys II immunoassay, with AS defined as a stimulated cortisol of <500nmol/L ("historical threshold") and <400nmol/L ("revised threshold"). RESULTS: Mean age at enrolment was 5.41±0.86 years (N=118). At Week 24, proportion of participants with AS using the historical and revised cortisol thresholds, respectively, were as follows: prednisone 0.75 mg/kg/day=100% (25/25) and 92.0% (23/25); vamorolone 6 mg/kg/day=95.2% (20/21) and 90.5% (19/21); vamorolone 2 mg/kg/day=84.2% (16/19) and 47.5% (9/19); and placebo=20.0% (4/20) and 0% (0/20). Morning and peak ACTH-stimulated cortisol were strongly correlated in steroid-treated boys (Spearman correlation week 48=0.83). CONCLUSIONS: AS after vamorolone and prednisone was frequent and vamorolone-associated AS appeared dose-dependent. A lower stimulated cortisol threshold may be appropriate when using a monoclonal assay. We recommend hydrocortisone for glucocorticoid stress dosing in patients receiving vamorolone.

Diffuse Maculopapular Dermatitis Associated With Leuprorelin Acetate Androgen Deprivation Therapy.

Androgen deprivation therapy (ADT) is one of the effective treatment methods for prostate cancer, often used with radiation therapy. Among the key ADT agents is leuprolide, a synthetic gonadotropin-releasing hormone agonist, which effectively suppresses testosterone production which is a requisite for the growth and division of prostate cancer cells. However, leuprolide is associated with several well-known side effects and less common dermatological reactions. In this case, we present an 80-year-old male patient with stage IIB prostate cancer who developed diffuse maculopapular dermatitis following leuprolide acetate ADT. The patient first experienced mild dermatitis following the fifth monthly 7.5 mg leuprolide injection before it developed into a general body rash after six injections. The dermatitis manifested on the patient's arms, thighs, calves, dorsum, and back of hands but sparing the abdomen, face, and neck. The pruritic dermatitis was managed successfully with a three-week course of prednisone which led to complete resolution without long-term sequelae. This case highlights the importance of recognizing and managing dermatological side effects associated with ADT. Clinicians should maintain an index of suspicion and act promptly when these side effects manifest. Systematic reporting and further research are essential to enhance patient safety and understanding of drug-related dermatological manifestations.

Activation of the PGC-1α-mediated mitochondrial glutamine metabolism pathway attenuates female offspring osteoarthritis induced by prenatal excessive prednisone.

Osteoarthritis is a chronic, age-related joint disease. Previous studies have shown that osteoarthritis develops during intrauterine development. Prednisone is frequently used to treat pregnancies complicated by autoimmune diseases. However, limited research has been conducted on the enduring effects of prednisone use during pregnancy on the offspring. In this study, we investigated the effect of excessive prednisone exposure on cartilage development and susceptibility to osteoarthritis in the offspring. We found that prenatal prednisone exposure (PPE) impaired cartilage extracellular matrix (ECM) synthesis, resulting in poor cartilage pathology in female offspring during the adult period, which was further exacerbated after long-distance running stimulation. Additionally, PPE suppressed cartilage development during the intrauterine period. Tracing back to the intrauterine period, we found that Pred, rather than prednisone, decreased glutamine metabolic flux, which resulted in increased oxidative stress, and decreased histone acetylation, and expression of cartilage phenotypic genes. Further, PGC-1α-mediated mitochondrial biogenesis, while PPE caused hypermethylation in the promoter region of PGC-1α and decreased its expression in fetal cartilage by activating the glucocorticoid receptor, resulting in a reduction of glutamine flux controlled by mitochondrial biogenesis. Additionally, overexpression of PGC-1α (either pharmacological or through lentiviral transfection) reversed PPE- and Pred-induced cartilage ECM synthesis impairment. In summary, this study demonstrated that PPE causes chondrodysplasia in female offspring and increases their susceptibility to postnatal osteoarthritis. Hence, targeting PGC-1α early on could be a potential intervention strategy for PPE-induced osteoarthritis susceptibility.

Prevalence, Causes and Outcomes of Acute Gastrointestinal Bleeding in Rheumatoid Arthritis: A Systematic Review and Meta-Analysis.

Aim: The present study aims to investigate the prevalence, causes and outcomes of acute gastrointestinal (GI) bleeding in Rheumatoid arthritis (RA). Methods: A systemic search was conducted from electronic databases (PubMed/Medline, Cochrane Library, and Google Scholar) from inception to 14th November 2023. All statistical analyses were conducted in Review Manager 5.4.1. Studies meeting inclusion criteria were selected. A random-effect model was used when heterogeneity was seen to pool the studies, and the result was reported in prevalence and their corresponding 95% confidence interval (CI). Other outcomes were assessed using qualitative analysis. Results: A total of eight studies (six observational studies and 2 trials were used to conduct this systematic review and meta-analysis. A total population of 138,041 patients was used. Pooled analysis showed a statistically significant risk of GI bleeding in RA patients receiving NSAIDs (prevalence = 2% (1%, 3%); P < 0.00001; I2 = 98%). Qualitatively, causes and outcomes were discussed. Conclusion: Our study showed that 2% RA patients were subjected to GI bleeding, when they used NSAIDs. Other causes of GI bleeding were age-related factors, cardiovascular events, history of GI complications, and peptic ulcers. Outcome varied by the use of specific NSAIDs and the presence of comorbidities. Recent guidelines for the management of RA may mention GI bleeding as a potential complication, but the level of emphasis placed on this issue varies. Some guidelines provide comprehensive recommendations for its prevention and management, while others offer limited guidance.

Development of hyaluronic acid hydrogel containing prednisolone-encapsulated nonphospholipid liposomes for the treatment of rheumatoid arthritis.

Rheumatoid arthritis (RA) requires therapeutic approaches that alleviate symptoms and inhibit the progression of joint damage. Glucocorticoids (GCs) have been a cornerstone of RA treatment, yet their use is often limited by side effects. Recent advancements suggest that liposome-based delivery systems can improve GC biodistribution, minimizing toxicity. This study introduces an innovative tool for RA treatment using prednisone-encapsulated nonphospholipid liposomes (NPLs) in combination with a hyaluronic acid (HA) hydrogel. Our methodology involved incorporating prednisone (PR) with palmitic acid and cholesterol to formulate stable NPLs using a thin-film hydration technique. The synthesized PR-NPLs, characterized by a mean size of 150 nm, demonstrated uniform distribution and higher drug encapsulation in comparison with conventional phospholipid liposomes. In vitro assays revealed that PR-NPL markedly reduced inflammatory responses in macrophages. Additionally, we successfully incorporated PR-NPL into an HA hydrogel, employing a photoinitiated cross-linking process. This novel composite offered modulable PR release, governed by the degree of hydrogel cross-linking. The developed system presents a promising advancement in RA management, especially suited for intraarticular injections. It potentially enables targeted, controlled drug release with a reduced risk of side effects, signifying a significant improvement over existing RA therapies.
