Abstract

This Cross-sectional observational study was conducted to determine the clinical profile of drug-resistant tuberculosis in children. Patients were classified as monoresistant TB, polyresistant TB, multidrug resistant (MDR)-TB and extensively drug resistant (XDR — TB). We coined a term called as Partial XDR-TB when isolates of Mycobacterium tuberculosis were confirmed to be resistant in vitro to be MDR along with either a fluoroquinolone or an aminoglycoside resistance (apart from streptomycin). Of 500 children analysed, 34 (6.8%) had drug resistant TB. Mean age of presentation was 6.8±3.2 years (Male: Female ratio 13:21). 18 (52.9%) children had been treated for tuberculosis in the past (1 defaulted), 7 patients had been in contact with an adult suffering from drug resistant TB and 3 patients (10.3%) were HIV co-infected. Fourteen children (41.2 %) had MDR TB, 11 (32.4 %) had Partial XDR, 1 each (2.9 %) had polyresistant TB and XDR TB. Clinical features of DR-TB are similar in all age groups. Past history of TB with treatment with antitubercular agents, and contact with adults suffering with drug-resistant TB are important risk factors in development of drug-resistant -TB in children.
