(MTB) is an under-recognised cause of genitourinary disease. IgA nephropathy (IgAN), a leading cause of glomerulonephritis worldwide, has been described as a rare consequence of disseminated MTB infection. In this case report, we present the first case of MTB associated IgAN in Africa. Finding IgAN on kidney biopsy in an MTB endemic area should prompt a thorough investigation for MTB to increase the chance of remission of IgAN and prevent inappropriate use of immunosuppression.

Immunoglobulin A nephropathy (IgAN), the most prevalent primary glomerulonephritis globally, is characterized by mesangial IgA deposition and heterogeneous clinical trajectories. Historically, management relied on renin-angiotensin system inhibition and empirical immunosuppression, yet high lifetime kidney failure risk persists despite optimized care. This review synthesizes advances in molecular pathogenesis, highlighting how the traditional multi-hit hypothesis-while foundational for targeted therapy development-fails to capture IgAN's recurrent, self-amplifying nature.

Background: This study aimed to evaluate the efficacy and safety of telitacicept versus mycophenolate mofetil (MMF) in high-risk progressive immunoglobulin A nephropathy (IgAN).
Methods: This retrospective, multicentre cohort study included patients with high-risk progressive IgAN who received telitacicept or MMF therapy, both combined with low-dose steroids. Clinical data were collected from treatment initiation to 12 months.

Introduction: Severe community-acquired pneumonia (SCAP) in immunocompromised patients is often caused by rare atypical pathogens, which are difficult to detect using conventional microbiological tests (CMTs) and can progress to sepsis in severe cases. Metagenomic next-generation sequencing (mNGS), an emerging pathogen detection technique, enables rapid identification of mixed infections and provides valuable guidance for clinical treatment decisions. SCAP-induced sepsis caused by a six-pathogen co-infection has not been previously reported, but interpretation remains a challenge.

Sodium-glucose cotransporter 2 inhibitors reduced proteinuria in patients with IgA nephropathy; however, their efficacy in patients at high risk of progression receiving immunosuppressive agents and renin angiotensin-aldosterone system inhibitors remains unclear. After 3 months of low-dose steroid alone or combined with mycophenolate mofetil, as well as renin angiotensin-aldosterone system inhibitors treatment, 105 biopsy-proven IgA nephropathy patients with proteinuria greater than 0.5 g/d were included in this study.

Background: The Therapeutic Effects of Steroids in IgA Nephropathy Global (TESTING) trial demonstrated that glucocorticoid therapy reduced proteinuria and improved kidney outcomes in patients with Immunoglobulin A Nephropathy (IgAN). Galactose-deficient IgA1 (Gd-IgA1) plays a central role in IgAN pathogenesis by promoting immune complex formation. However, the effects of glucocorticoid on pathogenic IgA levels remain unclear.
