BACKGROUND: Dimercaptosuccinic acid (DMSA) therapy is a kind of chelation therapy for patients with Wilson 's disease (WD). While there have been reports of side effects associated with DMSA, the development of membranous nephropathy as a result of this therapy is uncommon.
CASE PRESENTATION: We present a case of a 19-year-old male patient with Wilson's disease who experienced proteinuria while receiving long-term DMSA treatment. Further evaluation revealed abnormally low levels of serum ceruloplasmin and serum albumin, as well as a 24-hour urinary protein excretion of 4599.98 mg/24 h. A renal biopsy confirmed the presence of membranous nephropathy. After ruling out other potential causes, we determined that the patient's membranous nephropathy was likely caused by DMSA. Following treatment with glucocorticoids, there was a significant reduction in proteinuria.
CONCLUSION: This case highlights the possibility of DMSA-induced membranous nephropathy and the importance of considering this diagnosis in patients receiving DMSA treatment. Given the widespread use of DMSA in the treatment of Wilson's disease, further research is needed to fully understand the potential role of this drug in the development of membranous nephropathy.
