Abstract

We determined mycobacterial drug resistance and HIV prevalence among children with bacteriologically confirmed tuberculosis (TB) from March 2013 to February 2017. Results were compared with 5 previous 2-year surveillance studies (2003-2013). Prospective surveillance of all bacteriologically confirmed TB in children (0-13 years) completed at Tygerberg Hospital, Cape Town, South Africa. Drug susceptibility testing was done by GenoType MTBDRplus for isoniazid and rifampicin; ofloxacin and amikacin drug susceptibility testing was completed if rifampicin resistance was detected. Xpert MTB/RIF was routinely introduced during this period. Six hundred sixty-two children, median age 34 months (interquartile range 14-79) had bacteriologically confirmed TB; 587 (88.7%) were culture-confirmed and 75 (11.3%) confirmed by Xpert MTB/RIF only. Of culture-confirmed cases, 509 (86.7%) were pan-susceptible, 47 (8.0%) were multidrug-resistant, 13 (2.2%) were RIF-resistant/INH-susceptible and 18 (3.1%) were INH-resistant/RIF-susceptible. Of Xpert-positive cases, 3/75 (4%), 68/75 (92%) and 4/75 (5%) were RIF-resistant, RIF-susceptible and RIF-indeterminate, respectively. Of 573 (97.6%) children tested, 74 (12.9%) were HIV positive. Compared with pre...Continue Reading
