IgA vasculitis with severe renal manifestation

Area of Science:

• Nephrology
• Rheumatology
• Immunology

Background:

• IgA vasculitis (IgAV) is a rare systemic vasculitis.
• Adult IgAV often presents with more severe manifestations than in pediatric cases.
• IgAV commonly involves the skin, joints, gastrointestinal tract, and kidneys.

Observation:

• A man in his 40s presented with IgA vasculitis affecting multiple organ systems.
• The patient exhibited significant proteinuria and renal biopsy confirmed crescentic glomerulonephritis.
• This indicated severe renal impairment secondary to IgA vasculitis.

Findings:

• Early immunosuppressive therapy, including corticosteroids and cyclophosphamide, was initiated.
• Renal biopsy findings post-treatment demonstrated a positive response to immunosuppression.
• The patient experienced a favorable outcome despite the initial severity of renal involvement.

Implications:

• This case highlights the potential for severe renal impairment in adult IgA vasculitis.
• Prompt diagnosis and aggressive immunosuppressive therapy can lead to good renal outcomes.
• The findings support the efficacy of combined corticosteroid and cyclophosphamide treatment in severe IgAV-related glomerulonephritis.
