Insights

The novel coronavirus disease 2019 (COVID-19) may trigger polymyalgia rheumatica (PMR), an autoimmune condition. Prompt treatment with prednisolone effectively managed the patient's symptoms, suggesting a link between SARS-CoV-2 infection and PMR onset.

Area of Science:

  • Rheumatology
  • Infectious Diseases
  • Immunology

Background:

  • Polymyalgia rheumatica (PMR) is an inflammatory condition typically affecting individuals over 50.
  • The etiology of PMR is often idiopathic, but viral triggers have been suspected.
  • The emergence of SARS-CoV-2 has raised questions about its potential to trigger autoimmune responses.

Observation:

  • An 81-year-old male with diabetes and hypertension developed bilateral shoulder and hip pain 3 days after COVID-19 diagnosis.
  • Symptoms consistent with PMR appeared one month after initial SARS-CoV-2 infection onset.
  • The patient presented to an outpatient clinic for evaluation of persistent pain.

Findings:

  • Diagnostic criteria for polymyalgia rheumatica were met.
  • Treatment with 15 mg of prednisolone daily resulted in immediate symptom improvement.
  • The clinical presentation strongly suggests SARS-CoV-2 infection as a trigger for PMR.

Implications:

  • This case highlights a potential novel association between SARS-CoV-2 infection and the development of polymyalgia rheumatica.
  • Understanding post-COVID-19 autoimmune manifestations is crucial for patient management.
  • Further research is warranted to explore the immunopathogenesis linking SARS-CoV-2 to PMR.
