Effect of pulsed intravenous methylprednisolone with alternative low-dose prednisone on high-risk IgA nephropathy: a 18-month prospective clinical trial

Full-dose prednisone (FP) regimen in the treatment of high-risk immunoglobulin A nephropathy (IgAN) patients, is still controversial. The pulsed intravenous methylprednisolone combined with alternative low-dose prednisone (MCALP) might have a more favorable safety profile, which has not been fully investigated. Eighty-seven biopsy-proven IgAN adult patients and proteinuria between 1 and 3.5 g/24 h after ACEI/ARB for at least 90 days were randomly assigned to 6-month therapy: (1) MCALP group: 0.5 g of methylprednisolone intravenously for three consecutive days at the beginning of the course and 3rd month respectively, oral prednisone at a dose of 15 mg every other day for 6 months. (2) FP group: 0.8–1.0 mg/kg/days of prednisone (maximum 70 mg/day) for 2 months, then tapered by 5 mg every 10 days for the next 4 months. All patients were followed up for another 12 months. The primary outcome was complete remission (CR) of proteinuria at 12 months. The percentage of CR at 12th and 18th month were similar in the MCALP and FP groups (51% vs 58%, P = 0.490, at 12th month; 60% vs 56%, P = 0.714, at 18th month). The cumulative dosages of glucocorticoid were less in the MCALP group than FP group (4.31 ± 0.26 g vs 7.34 ± 1.21 g, P < 0.001). The analysis of the correlation between kidney biopsy Oxford MEST-C scores with clinical outcomes indicated the percentages of total remission was similar between two groups with or without M1, E1, S1, T1/T2, and C1/C2. More patients in the FP group presented infections (8% in MCALP vs 21% in FP), weight gain (4% in MCALP vs 19% in FP) and Cushing syndrome (3% in MCALP vs 18% in FP). These data indicated that MCALP maybe one of the choices for IgAN patients with a high risk for progression into ESKD.Trial registration: The study approved by the Chinese Clinical Trial Registry (registration date 13/01/2018, approval number ChiCTR1800014442, https://www.chictr.org.cn/).

A case of immune-complex mediated glomerulonephritis associated with pembrolizumab

Introduction: Immune checkpoint inhibitors (ICI) are changing the way we treat cancer. However, these novel agents have various systemic adverse events that may preclude its use and cause poor patient outcomes. ICI-associated acute kidney injury is an emerging complication of this treatment. While tubulointerstitial disease is the most common pathologic finding of patients with ICI-associated AKI, there is sparse data in medical literature describing its association with glomerular disease. Case report: Here, we present a patient with metastatic lung adenocarcinoma who developed acute kidney injury and significant proteinuria after receiving pembrolizumab. The kidney biopsy revealed a membranoproliferative and diffuse segmental endocapillary proliferative pattern of glomerular injury. Management and outcome: Pembrolizumab was then held and high-dose prednisone was initiated, resulting in a rapid and dramatic improvement in kidney function and proteinuria. Discussion: We highlight a report of a patient diagnosed with immune-complex mediated glomerulonephritis associated with the use of pembrolizumab, who was successfully treated with drug withdrawal and corticosteroids.

Nivolumab-Induced Exocrine Pancreatic Insufficiency

Immunotherapy is increasingly gaining applicability for several malignancies. While the survival of several malignancies has dramatically improved, immune-related adverse events (irAEs) can occur and can cause severe damage to patients. Side effects such as colitis are well known nowadays; however, with increased use of immunotherapy, less common side effects should also be addressed. In this article, 2 patients that received nivolumab developed exocrine dysfunction of the pancreas. Endocrine dysfunction has been well known, but exocrine dysfunction is less often described. It is important to be aware of this side effect because it is possibly underdiagnosed. Symptoms often mimic symptoms of malignancy, chemotherapy side effects, or immune-related colitis. Although the exact mechanism is yet to be elaborated, dormant CD8+ T cells are likely to be involved. No known therapy is yet been proven to be effective. More knowledge and research about irAEs will lead to possible therapies that will be effective. Currently, high-dose prednisone is recommended based on expert opinion.

95 Baseline body-mass-index and risk for obesity in children with rheumatic disease starting high-dose prednisone therapy

Primary Subject area Rheumatology Background Prednisone is a glucocorticoid (GC) medication commonly used in moderate (&gt;7.5 mg/day) to high doses (≥ 1 mg/kg/day to maximum 60 mg/day) for children with moderate to severe presentations of rheumatic disease, including systemic lupus erythematosus (SLE), juvenile idiopathic arthritis (JIA), and juvenile dermatomyositis (JDM). Adverse effects (AE) to GCs impose a significant burden on health and quality of life including frequent development of weight gain, mood changes, sleep difficulties, osteoporosis, and Cushingoid features, amongst others. Objectives We sought to evaluate a possible relationship between baseline patient body-mass-index (BMI) measure and development of select GC-mediated toxicity within the first 12 months of starting moderate or high-dose prednisone therapy using conventional weight-based dosing of prednisone. Secondary outcomes were to examine rates of GC-mediated hypertension, osteopenia, and osteoporosis. Design/Methods We performed a retrospective chart review on children with rheumatic disease aged ≤ 17 years treated with moderate and high-dose prednisone therapy at a single Canadian academic hospital between January 1, 2010 and December 31, 2019. Demographic variables collected included diagnosis, age, sex, ethnicity. Clinical variables collected include weight, height, and body-mass-index (BMI), hepatitis (AST&gt;41 U/L, ALT&gt;40 U/L, or GGT&gt;60 U/L), proteinuria (&gt;0.1 g/L), and presence of hypoalbuminemia (&lt;38g/L) at baseline. We collected weight, height, and body-mass-index (BMI), at 6 and 12 months, the maximum BMI, and transformed them to z-scores according to the World Health Organization's Child Growth standards. Cumulative prednisone dose (mg/kg/12 months), total days on prednisone in the first 12 months of therapy were also obtained, in addition to bone-mineral-density cores after 12 months of prednisone therapy. Baseline characteristics, which were significant for the subsequent development of obesity during the first 12 months at the bivariate level (p &lt; 0 .05), were included as predictors of obesity in separate logistic regression analyses. In each regression analysis, we also adjusted for baseline BMI, and for confounding variables of hepatitis, hypoalbuminemia (albumin less than 38 grams per litre), proteinuria and prednisone dose. We conducted a complete case analysis, and all analyses were performed using SPSS v.26 (IBM Corp., Armonk, NY, USA), and p-values &lt; 0 .05 were considered statistically significant. Results Seventy-four charts were reviewed, and 72 patients met criteria for analysis. The median prednisone dose was 35 mg per day (IQR 20 to 60 mg), and median duration of therapy was 302 days (IQR 126.75 to 581.25). Thirty-five (48.6%) patients developed obesity, 33 (45.8%) hypertension, five (7.0%) osteopenia, and three (4.2%) osteoporosis. Greater BMI at baseline was associated with greater total weight gain (OR 4.04, 95% CI = [1.98-8.33], p &lt; 0 .001). Conclusion Greater baseline patient BMI may be a predictor of weight gain on high-dose prednisone therapy in children with rheumatic disease requiring high-dose therapy. Further work is required to determine methods for individualized prednisone dosing and counseling and behavioral interventions to mitigate risk for weight gain.

Case Report: ISPD Gene Mutation Leads to Dystroglycanopathies: Genotypic Phenotype Analysis and Treatment Exploration

ISPD gene mutation-related diseases have high clinical and genetic heterogeneity, and no studies have yet reported any effective treatments. We describe six patients with dystroglycanopathies caused by ISPD gene mutations and analyze their genotypes and phenotypes to explore possible effective treatments. Our results confirm that the phenotype of limb-girdle muscular dystrophies can be easily misdiagnosed as Duchenne muscular dystrophy and that exon deletions of ISPD gene are relatively common. Moreover, low-dose prednisone therapy can improve patients' exercise ability and prolong survival and may be a promising new avenue for ISPD therapy.

The efficacy of low dose short-term prednisone therapy for remission induction in newly diagnosed rheumatoid arthritis patients

Background The ACR/EULAR recommendations endorse the use of glucocorticoids (GCs) for rheumatoid arthritis (RA) patients’ flares and as a bridge to a DMARD. However, the recommendation of low dose short-term monotherapy with (GCs) remains open to the discretion of the clinician. The aim of this study was to assess whether a short-term use of low dose prednisone monotherapy was effective in inducing remission in newly diagnosed RA patients. Methods A retrospective analysis of patients newly diagnosed with RA at a Community Health Center in North Dakota was performed based on the ACR/EULAR RA classification criteria. Demographic and clinical data were abstracted from patients’ medical charts. Patients treated with (< 10 mg/day) of prednisone up to 6 months were included. Response to prednisone was analyzed according to pre- and post-treatment DAS28-ESR score and EULAR response criteria. Results Data on 201 patients were analyzed. The mean prednisone dose was 8 mg/day (range: 5–10; SD = 1.2) and the mean treatment duration was 42.2 days (12–177; 16.9). Disease severity significantly improved from baseline to follow-up for: tender joint count (8.6 ± 4.8 vs. 1.5 ± 3.3; P < 0.001), swollen joint count (6.2 ± 5.0 vs. 1.4 ± 3.0; P < 0.001), and visual analog pain score (4.8 ± 2.6 vs. 2.1 ± 2.5; P < 0.001). DAS28-ESR disease severity significantly improved from baseline to follow-up: (5.1 ± 1.2 vs. 2.7 ± 1.3; P < 0.001). Per EULAR response criteria, 69.7% of patients showed good response to treatment and 20.4% showed moderate response. 54.2% of patients reached remission. Conclusion Short-term use of low dose prednisone monotherapy induced disease remission and improved clinical severity of RA in the majority of newly diagnosed patients.

Myelodysplastic Syndrome with Excess of Blasts - Long Term Partial Remission with Low Dose Prednisone, G-CSF and Epoetin Alfa

We have used low-dose prednisone, in conjunction with granulocyte, colony-stimulating factor (G-CSF) and erythropoietin, to treat an elderly patient with myelodysplastic syndrome (MDS) with an excess of blasts. Our findings indicate that such treatment is safe and may be effective in the long term survival of patients with high-risk MDS.
