A Predicting Tool for Kidney Function Recovery after Drug-Induced Acute Interstitial Nephritis.

Background: Drug-induced acute interstitial nephritis (DI-AIN) represents a common cause of acute kidney injury. Early withdrawal of the culprit drug and corticosteroid therapy remains the mainstay of treatment.This study aimed to develop and validate a predictive nomogram to assess the probability of recovery of kidney function at 6 months after treatment.

Indications for genetic testing in adults with focal segmental glomerulosclerosis.

Focal segmental glomerulosclerosis (FSGS) is a histological pattern of injury that derives from various pathological processes that affect podocytes, resulting in loss of selectivity of the glomerular filtration membrane, proteinuria and the development of renal failure that progresses to end-stage kidney disease in a significant number of patients. The classification proposed by the 2021 KDIGO guidelines divides FSGS into four categories: primary, secondary, genetic, and FSGS of undetermined cause, thus facilitating its diagnosis and management. Genetic causes of FSGS present significant clinical variability, complicating their identification.

Recommendations for the diagnosis and treatment of anti-neutrophil cytoplasmic autoantibody associated vasculitis.

Anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis is characterised by small vessel necrotising inflammatory vasculitis. Prior to immunosupressant therapy availability it usually led to a fatal outcome. Current treatment has changed ANCA-associated vasculitis into a condition with a significant response rate, although with a not negligible relapse occurrence and cumulative organ lesions, mostly due to drug-related toxicities.

Tailored management strategies for IgA nephropathy based on clinical presentations.

The treatment landscape for IgA nephropathy (IgAN) is rapidly evolving with the introduction of novel therapies targeting diverse disease pathways. Some have already been approved in different countries, while others are under investigation in randomized controlled trials (RCTs) with encouraging results. However, almost all performed RCTs have included only patients with refractory non-nephrotic proteinuria and preserved renal function.

Prognostic and therapeutic monitoring value of plasma and urinary cytokine profile in primary membranous nephropathy: the STARMEN trial cohort.

Background: Primary membranous nephropathy (PMN) is usually caused by anti-phospholipase A2 receptor (PLA2R) autoantibodies. There are different therapeutic options according to baseline risk. Novel biomarkers are needed to optimize risk stratification and predict and monitor the response to therapy, as proteinuria responses may be delayed.
