Summary
Granulomatosis with polyangiitis (GPA) can relapse decades after initial diagnosis. This case highlights the importance of complete immunological recovery to prevent severe organ damage, particularly kidney failure, in ANCA-associated vasculitis patients.
Area of Science:
- Nephrology
- Rheumatology
- Immunology
Background:
- Granulomatosis with polyangiitis (GPA) is a rare ANCA-associated vasculitis with significant mortality risk due to multiorgan involvement.
- Key features include respiratory tract granulomas, small/medium vessel vasculitis, and glomerulonephritis, necessitating early treatment to prevent end-stage kidney disease.
Observation:
- A unique case of GPA relapse occurred 38 years after initial pulmonary presentation.
- The patient, previously with isolated lung disease and normal renal function, presented with acute kidney injury, uremia, and constitutional symptoms.
Findings:
- Treatment involved corticosteroids, intermittent hemodialysis, and immunosuppressants.
- The patient achieved eventual renal recovery, underscoring the effectiveness of comprehensive treatment.
Implications:
- This case emphasizes the critical need for complete immunological recovery in GPA management to prevent relapses.
- Preventing further renal function loss is paramount, especially in ANCA-associated vasculitis, to avoid irreversible organ damage like end-stage kidney disease.

01:27Acute Pyelonephritis I: Introduction
1.5K
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

01:28Acute Pyelonephritis II: Diagnostic Studies and Management
842
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...

01:24Nephrotic Syndrome I : Introduction
1.2K
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...

409
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

01:12Chronic Inflammation: Introduction
41
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
