Vigilance Needed in Treating a Child with Disseminated TB: A Case Report

Background Tuberculosis is still one of the biggest causes of infection-related death around the world. Disseminated tuberculosis is a potentially fatal disease caused by the haematogenous spread of Mycobacterium tuberculosis . First-line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide, and ethambutol. The first three drugs are known to cause hepatotoxicity. Case presentation We have, herein, reported a case of Drug-induced Liver Injury (DILI) due to anti-tuberculosis therapy in a one-year-old male child with disseminated tuberculosis. He was started on a fixed-dose combination of Anti-tuberculosis Therapy (ATT; isoniazid 50 mg, rifampicin 75 mg, and pyrazinamide 150 mg) and pyridoxine 10 mg orally. Initially, liver parameters were normal, but later on with the course of the treatment, there was a rapid rise in liver enzymes, suggesting liver injury. Discussion The association between liver injury and anti-tuberculosis therapy has been confirmed by applying various causality association scales. It is obvious that proper treatment of disseminated tuberculosis can avoid the development of drug-resistant strains that can be harmful, worsening the prognosis as there are fewer therapeutic alternatives available. At the same time, there is a need to monitor the patient with ATT-induced DILI. Conclusion The diagnosis of tuberculosis in children is difficult because of the mild, nonspecific clinical presentation, which usually reflects the implicated underlying organ. In addition to prompt diagnosis and treatment of disseminated TB, careful monitoring is equally important.
