Granulomatosis with polyangiitis with rapidly progressive glomerulonephritis treated with a multipronged approach-a case based review.

Granulomatosis with polyangiitis is an ANCA-associated vasculitis that involves small to medium-sized vessels. The extent of renal involvement varies, which is also associated with disease prognosis, with aggressive renal involvement having worse outcomes. Rapidly progressive glomerulonephritis with severe inflammatory features and extensive crescent formation can be challenging to treat.

SUrvey of renal Biopsy registry database and Anticancer dRUg therapy in Japan (SUBARU-J study).

Background: Kidney complications associated with anticancer drug therapy have greatly increased recently. We aimed to investigate the real-world clinical outcomes of anticancer drug therapy-associated renal complications in Japan using the national kidney biopsy database, Japan Renal Biopsy Registry (J-RBR).

Methods: From 2018 to 2021, 449 cases from 49 facilities identified as 'drug-induced' histopathology in the J-RBR were screened, of which a total of 135 were confirmed as anticancer drug-related cases and included in the analysis.

Microscopic polyangiitis in pediatric systemic lupus erythematosus: a unique presentation of pulmonary-renal syndrome and case report of an overlap syndrome.

Secondary vasculitis is encountered in about one-third of all cases of systemic lupus erythematosus (SLE). Skin is most commonly involved in lupus-related small vasculitis. Although antineutrophil cytoplasmic autoantibodies (ANCA) associated vasculitis (AAV) is relatively uncommon, it can be the most dangerous manifestation associated with high mortality.

Crescentic Glomerulonephritis in Human Immunodeficiency Virus Infection.

The spectrum of kidney disease among human immunodeficiency virus (HIV) infected patients is extensive. We describe a young male who was recently detected with HIV infection and antineutrophil cytoplasmic antibody (ANCA) negative pauci-immune crescentic glomerulonephritis. The patient had no extrarenal vasculitis involvement.

Rapidly Progressive Glomerulonephritis.

Rapidly progressive glomerulonephritis (RPGN) is a syndrome characterized by a swift decline in kidney function, often over a few months, accompanied by features of nephritic syndrome. It can result in decreased urine output and commonly involves the presence of extensive crescents in kidney biopsies. RPGN is classified into 3 main types based on immune deposit distribution and visualization through immunofluorescence and electron microscopy: antiglomerular basement membrane disease, immune complex glomerulonephritis, and pauci-immune glomerulonephritis.

Atypical anti-GBM disease in pregnancy.

A woman in her 20s presented with nephrotic syndrome and hyperemesis in early pregnancy. Pertinent initial investigations revealed a severe acute kidney injury, a serum albumin of 19 g/L, a random protein creatinine ratio of 800 g/mol and microscopic haematuria. All immunological and infection serology testing including anti-glomerular basement membrane (anti-GBM; ELISA) were negative.

Rapidly Progressive Glomerulonephritis Associated With IgA Nephropathy and C3 Deposits in a Patient With Chronic Hepatitis B.

Hepatitis B-associated glomerulonephritis (GN) has been recognized for decades. However, only a few cases of IgA nephropathy (IgAN) in a setting of rapidly progressive glomerulonephritis (RPGN) associated with chronic hepatitis B virus (HBV) have been described. Herein, we report the case of a 42-year-old Asian female with a past medical history significant for chronic HBV on entecavir, hypertension, chronic kidney disease, and newly diagnosed breast cancer, who underwent elective bilateral mastectomy and breast augmentation.

Relationship of body mass index and kidney outcomes in patients with primary glomerulonephritis: A systematic review and meta-analysis.

Background: Primary glomerulonephritis, is a major contributor to the development of chronic kidney disease and end-stage renal disease. Previous studies on the relationship between overweight/obesity with primary glomerulonephritis in the chronic kidney disease was inconsistent. This study aimed to systematically review and meta-analyze the relationship between body mass index and adverse kidney outcomes in patients with primary glomerulonephritis.

Crescentic Glomerulonephritis and Portal Hypertension with Chronic Q Fever: A Case Report and Comprehensive Literature Review.

Q fever, an infectious zoonotic disease caused by , remains prevalent in China. Systemic infections can result in renal or hepatic complications; however, it is rare for both the kidneys and liver to be simultaneously affected. We present a case of a patient who exhibited fever, rapid deterioration in renal function, thrombocytopenia, and severe ascites.

Dual blockade of endothelin A and angiotensin II type 1 receptors with sparsentan as a novel treatment strategy to alleviate IgA nephropathy.

Introduction: Although immunoglobulin A nephropathy (IgAN) had been discovered more than 50 years ago, 30-40% of IgAN patients still have primary glomerular disease that progresses to end-stage renal disease. However, various treatment strategies for IgAN have rapidly expanded in recent years to include endothelin (ET) receptor antagonists.

Areas Covered: In this review, we discuss the role of the ET-1/ET receptor axis in the development of IgAN, especially focusing on the potential of sparsentan, a dual ET and angiotensin receptor antagonist as a novel therapy for IgAN.

Complete renal response of IgA vasculitis with steroid and mycophenolate mofetil in an adult HIV patient.

IgA vasculitis in adult HIV patients is rare and not well understood. Data on treatment of IgA vasculitis associated with HIV is sparse and limited to case reports. Highly active antiretroviral therapy (HAART) is the mainstay therapy for inducing remission.

The uncertain correlation of ANCAs in patients with lupus nephritis and crescents, an experience from Chinese centers.

Background: The precise role of anti-neutrophil cytoplasmic antibodies (ANCAs) in the pathologic course of crescentic lupus nephritis (LN) remains unclear. Our study aimed to assess whether ANCA-positive serology in patients with LN and crescents is associated with different clinicopathologic features and outcomes.

Methods: We reviewed the records of 658 patients diagnosed with LN between 2010 and 2022.

MEST C Score and Treatment Response in IgA Nephropathy in a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

Introduction: IgA nephropathy is the leading cause of primary glomerulonephritis worldwide. The Oxford classification can predict IgA nephropathy prognosis through renal biopsy however its applicability to the Nepalese population remains unexplored. This study aimed to evaluate the MEST-C score and treatment response in patients with IgA nephropathy.
