[Malignant, rapidly progressing nephritis in Schönlein-Henoch disease].

Area of Science:

• Nephrology
• Rheumatology
• Pathology

Background:

• Henoch-Schönlein nephritis (HSN) is a systemic vasculitis often affecting children.
• While typically self-limiting, severe or rapidly progressive forms can occur.
• This case highlights a rare, aggressive presentation in an adult.

Observation:

• A patient presented with typical systemic vasculitis symptoms: joint pain, skin rash, and severe abdominal pain.
• Rapidly developing renal involvement manifested as acute renal insufficiency, azotemia, electrolyte imbalance, and anemia.
• Pathological examination revealed severe diffuse intra- and extracapillary proliferative glomerulonephritis.

Findings:

• The patient experienced a fulminant course of HSN, leading to death within 1.5 months of symptom onset.
• Standard treatments including antihistamines, heparin, and corticosteroids were ineffective.
• The rapid progression and severity of renal pathology were notable.

Implications:

• This case underscores the potential for aggressive and fatal outcomes in Henoch-Schönlein nephritis.
• It emphasizes the need for early recognition and potentially novel therapeutic strategies for severe HSN.
• Understanding the pathomorphology of rapidly progressive glomerulonephritis is crucial for diagnosis and prognosis.
