Minimal-change Nephrotic Syndrome Associated with Isoniazid in Anti-tuberculosis Chemoprophylaxis for a Patient with Rheumatoid Arthritis

摘要

A 66-year-old woman with seropositive rheumatoid arthritis (RA) and latent tuberculosis infection developed minimal-change nephrotic syndrome following the initiation of anti-tuberculosis chemoprophylaxis with isoniazid. This is the first reported case of an isoniazid-induced nephrotic syndrome. Isoniazid as a single-drug intervention is widely accepted as a safe and effective means of anti-tuberculosis chemoprophylaxis, particularly for RA patients with latent tuberculosis infection; the present case, however, demonstrates that isoniazid has the potential to induce minimal-change nephrotic syndrome, even when used as a single-drug intervention.
