Acute interstitial nephritis with bone marrow granulomas and uveitis

Area of Science:

• Nephrology
• Rheumatology
• Immunology

Background:

• Rheumatoid arthritis (RA) is a chronic autoimmune disease.
• Interstitial nephritis is kidney inflammation.
• Uveitis is inflammation of the eye's middle layer.

Observation:

• A 53-year-old woman with RA presented with uremia.
• Renal biopsy showed acute interstitial nephritis with eosinophilic infiltration.
• The patient also exhibited bone marrow granulomas and uveitis.

Findings:

• The patient's presentation aligns with Dobrin et al. syndrome.
• Etiology and pathogenesis of this syndrome are currently unknown.
• Elevated erythrocyte sedimentation rate, high serum immunoglobulins, immune complexes, and decreased T-cells suggest immune system involvement.

Implications:

• This case highlights a rare syndrome potentially linked to autoimmune disorders.
• Further research is needed to understand the etiology and pathogenesis.
• Early recognition and investigation of immunological factors are crucial for patient management.
