Summary
Strongyloides stercoralis infection can mimic systemic vasculitis and reactive arthritis. Early diagnosis through parasitologic analysis and prompt treatment with ivermectin are crucial for favorable outcomes.
Area of Science:
- Infectious Diseases
- Rheumatology
- Parasitology
Background:
- Parasitic infections exhibit diverse clinical presentations.
- Strongyloides stercoralis is a nematode parasite with a wide range of potential manifestations.
Observation:
- A 77-year-old woman presented with polyarthritis, myalgia, fever, abdominal pain, and eosinophilia, initially suspected as polyarteritis nodosa.
- Prior treatment with steroids for polymyalgia rheumatica did not resolve symptoms.
Findings:
- Diagnosis of Strongyloides stercoralis infection was confirmed via parasitologic analysis of stool and colonic biopsies.
- The patient experienced a favorable outcome following treatment with ivermectin and steroid withdrawal.
Implications:
- Strongyloides stercoralis can present with symptoms mimicking systemic vasculitis and reactive arthritis.
- This case highlights the importance of considering parasitic infections in patients with unexplained inflammatory conditions.
- Prompt diagnosis and appropriate antiparasitic treatment are essential for managing Strongyloides stercoralis infections.
