Summary
Granulomatosis with polyangiitis (GPA), a type of ANCA-associated vasculitis (AAV), can relapse rarely. Rituximab effectively treated a patient with relapsing GPA, demonstrating its utility in managing this rare condition.
Area of Science:
- Immunology
- Rheumatology
- Nephrology
Background:
- Granulomatosis with polyangiitis (GPA) is the most common antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).
- GPA presents with diverse clinical manifestations, primarily affecting the respiratory tract and kidneys.
- Relapse is a significant concern in GPA management.
Purpose of the Study:
- To describe a rare case of relapsing GPA in a 38-year-old woman.
- To highlight the diagnostic challenges in distinguishing GPA relapse from immunosuppression side effects.
- To evaluate the efficacy of rituximab in treating refractory GPA.
Main Methods:
- Case report of a 38-year-old woman with relapsing GPA.
- Treatment with azathioprine followed by rituximab.
- Monitoring of clinical symptoms and ANCA titres.
Main Results:
- The patient presented with intracranial hypertension and cavitated lung nodules despite azathioprine.
- Rituximab treatment led to clinical improvement and reduction in ANCA titres.
- The case illustrates difficulties in differentiating GPA relapse from immunosuppression consequences.
Conclusions:
- ANCA-associated vasculitis (AAV) is a rare inflammatory condition affecting small to medium vessels.
- Granulomatosis with polyangiitis (GPA), often associated with PR3-ANCA, has a risk of relapse.
- Monitoring ANCA titres is crucial for early diagnosis of GPA recurrence and distinguishing it from immunosuppression effects.

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...
