Summary
Poncet disease, a rare joint inflammation linked to tuberculosis (TB), can occur even during TB treatment. This case shows joint symptoms resolving with continued anti-tuberculous therapy (ATT).
Area of Science:
- Rheumatology
- Infectious Diseases
- Pediatrics
Background:
- Poncet disease is an uncommon presentation of tuberculosis (TB), characterized by acute polyarthritis.
- It typically occurs without direct joint infection and resolves without lasting joint damage.
- Most cases are diagnosed when anti-tuberculous therapy (ATT) begins.
Observation:
- A 13-year-old female presented with Poncet disease affecting both knees.
- This occurred despite nearly six months of treatment for abdominal TB.
- A synovial biopsy of the affected joint yielded no microbial growth.
Findings:
- The patient's bilateral knee joint involvement resolved with the continuation of ATT.
- This case highlights a Poncet disease manifestation during ongoing TB treatment.
- Sterile synovial biopsy confirmed the non-septic nature of the joint inflammation.
Implications:
- Poncet disease can manifest or persist even during established anti-tuberculous therapy.
- Continuation of ATT is crucial for resolving joint symptoms in Poncet disease.
- This case underscores the importance of considering Poncet disease in pediatric patients with joint pain and concurrent TB.
