Area of Science:

  • Rheumatology
  • Neurology
  • Toxicology

Background:

  • Systemic lupus erythematosus (SLE) is an autoimmune disease.
  • Hydroxychloroquine and prednisolone are common SLE treatments.
  • Myopathy is a potential complication in SLE patients.

Observation:

  • A woman with SLE developed severe myopathy post-septicemia.
  • Her muscle biopsy showed no vasculitis, and creatine kinase levels were normal.
  • She was treated with hydroxychloroquine sulfate and prednisolone prior to admission.

Findings:

  • The patient's muscle strength improved with intensive physiotherapy and continued prednisolone.
  • The absence of vasculitis and normal creatine kinase levels suggested an alternative cause for myopathy.

  • Hydroxychloroquine was identified as a potential causative agent for the myopathy.

    • Implications:

    • This case highlights a potential adverse effect of hydroxychloroquine in SLE patients.
    • Early recognition and management of drug-induced myopathy are crucial.
    • Further research is needed to understand the link between hydroxychloroquine and myopathy in SLE.
