Purpose: To explore the effect of glucocorticoid on immune globulin A (IgA) nephropathy by meta-analysis.

Method: Search the data and literature libraries of ScienceDirect, EBSCO, Wiley, PubMed, CBMdisc, and CNKI and collect the literature on the treatment of IgA nephropathy with glucocorticoids as randomized controlled trials published at home and abroad from 1995 to 2021. The standardized mean difference (SMD) and 95% confidence interval () were calculated by fixed-effects model. RevMan 5.0 software was used for meta-analysis of the subgroups of overall curative effect, different degree of proteinuria, different course of treatment, different creatinine level, and combined ACEI.

Result: ① The overall efficacy of glucocorticoid in the treatment of IgA nephropathy was better than that in the control group ( = 0.00001). ② The efficacy of glucocorticoid treatment in patients with IgA nephropathy with proteinuria greater than 1.50 g/d and less than 1.50 g/d was better than that in the control group ( < 0.01). ③ For IgA nephropathy patients with serum creatinine less than 1.50 mg/dl, the curative effect of glucocorticoid treatment was better than that of the control group ( < 0.01). ④ The effects of short-term treatment (<1 year) and long-term treatment (≥1 year) with glucocorticoid were better than those in the control group ( < 0.01). ⑤ The effect of hormone combined with ACEI drugs on IgA nephropathy was more significant ( < 0.01).

Conclusion: The overall efficacy of glucocorticoid in the treatment of IgA nephropathy is accurate. Hormone treatment is effective for different degrees of IgA nephropathy. Considering that there is no significant effect on the efficacy of different courses of treatment, it is suggested that the course of hormone treatment can be appropriately shortened. Hormone combined with angiotensin-converting enzyme inhibitors (ACEI) can reduce proteinuria more effectively than ACEI drugs alone.

IgA nephropathy (IgAN) is a common primary glomerulonephritis characterized by the deposition of IgA immune complexes within the glomerular mesangium. IgAN can present with a wide range of clinical manifestations, ranging from asymptomatic hematuria to severe renal disease. This case describes a 67-year-old woman with a history of diabetes mellitus, hypertension, and obesity who presented with acute kidney injury and clinical manifestations of nephrotic syndrome.

Department of Traditional Chinese Medicine, Shengli Clinical Medical College of Fujian Medical University, Fujian Provincial Hospital, Fuzhou, China.

Background: Dense deposit disease (DDD) is a rare renal disorder major affecting adolescents and children, characterized by an absence of distinctive clinical symptoms. Its coexistence with other renal conditions complicates both diagnosis and treatment in clinical practice.

Case Presentation: We described a 15-year-old male adolescent presenting with nephrotic syndrome as the initial manifestation, with urinalysis indicating significantly elevated protein and erythrocytes.

Background: IgA nephropathy (IgAN) exhibits an unpredictable trajectory, creating difficulties in prognostication, monitoring, treatment, and research planning. This study provides a comprehensive depiction of the progression of kidney function throughout the disease course, from diagnosis to a span of 36 years post-diagnosis.

Methods: We utilized a cohort of 400 Norwegian IgAN patients, from diagnosis to the occurrence of death, initiation of kidney replacement therapy (KRT), or the latest follow-up.

Purpose: This study seeks to investigate the fundamental molecular processes through which histone deacetylase 9 (HDAC9) governs the proliferation of glomerular mesangial cells in the context of immunoglobulin A nephropathy (IgAN) and to identify novel targets for clinical research on IgAN.

Methods: Data from high-throughput RNA sequencing for IgAN were procured from the Gene Expression Omnibus database to assess the expression profiles and clinical diagnostic significance of histone deacetylase family proteins (HDACs). Blood samples from 20 IgAN patients were employed in RT-qPCR analysis, and the spearman linear regression method was utilized to analyze the clinical correlation.

Objectives: To study the significance of serum 25-hydroxyvitamin D [25-(OH)D] level in the clinicopathological characteristics and prognosis of children with immunoglobulin A vasculitis nephritis (IgAVN).

Methods: A retrospective analysis was conducted on the clinical data of children with IgAVN who underwent renal biopsy at Suzhou Hospital Affiliated to Anhui Medical University and Jinling Hospital of the Medical School of Nanjing University from June 2015 to June 2020. Based on serum 25-(OH)D level, the patients were divided into a normal group and a lower group.
