Abstract
Background: There are unique challenges in the diagnosis and management of multi drug resistant tuberculosis (MDR-TB) in children. It is difficult to obtain confirmatory microbiological diagnosis in TB pericarditis. It is essential to differentiate between drug sensitive and drug resistant forms of TB as it has a major bearing on the regimen used, and inappropriate TB treatment combined with steroid use for pericarditis can lead to deterioration. With lack of samples, the treatment decision relies on the drug resistance pattern of the close contact if available. Therapeutic challenges of MDR-TB management in a child involve use of toxic drugs that need to be judiciously handled. We report a 2 years 4 months old male child who was diagnosed with TB pericarditis and treated based on the resistance pattern of his mother who was on treatment for pulmonary MDR-TB.
Case presentation: This 2 years 4 months old male child was diagnosed with TB involving his pericardium. Getting him started on an appropriate regimen was delayed due to the difficulty in establishing microbiological confirmation and drug susceptibility. He was commenced on a regimen based on his mother’s drug resistance pattern and required surgery due to cardiac failure during the course of his treatment. He successfully completed 2 years of therapy.
Conclusions: This child’s case demonstrates that despite unique challenges in diagnosis and management of drug resistant extra pulmonary tuberculosis in children, treatment of even complex forms can be successful. The need for high suspicion of MDR-TB, especially when there is close contact with pulmonary TB, careful design of an effective regimen that is tolerated by the child, indications for invasive surgical management of pericarditis, appropriate follow-up and management of adverse effects are emphasised.
