Atypical anti-glomerular basement membrane disease: two case reports

Area of Science:

• Nephrology
• Autoimmunology
• Rare Diseases

Background:

• Atypical anti-glomerular basement membrane (anti-GBM) disease is a rare autoimmune disorder.
• It presents diagnostic and management challenges, differing from classic Goodpasture's disease.

Observation:

• Two cases of atypical anti-GBM disease were identified.
• These cases showed negative anti-GBM antibodies, minimal kidney biopsy findings, and no lung involvement.

Findings:

• The study highlights the diverse clinical spectrum of anti-GBM related conditions.
• High-dose steroid therapy led to favorable outcomes in both atypical cases.

Implications:

• This underscores the need for individualized treatment approaches in rare renal diseases.
• Further research is crucial to understand the pathophysiology and optimize management for atypical anti-GBM disease.
