ABSTRACT
Background. Childhood tuberculosis (TB) has been neglected by TB programs in Sub-Saharan Africa. The aim of this study was to determine the incidence and predictors of poor outcome in children with TB in the North region of Cameroon. Methods.It was a retrospective cohort study based on hospital TB registers and treatment TB forms, in all of the 18 functional diagnosis and therapeutic centers (DTC) in the North region. All children aged 0-15years, on anti-TB treatment between 2010-2016 were enrolled. Logistic regression was used to find independent factors associated to poor outcome. Results. Of the 668 children included [321 (48.1%) boys], the median (25th-75thpercentile) age was 11(6-14) years, with 75.9% children aged >5 years. Pulmonary TB was the most common (62.9%) with 34.3% smear-negative pulmonary TB. Extrapulmonary TB (62.1%) was mostly found in children aged 0-5years. HIV/TB coinfection was 10.3%. Incidence (95%CI) of poor outcome was 4.0 %( 2.5-5.5%). Predictors [OR (95%CI)] of poor outcome were: HIV positivechildren [3.995(1.131-14.112), p=0.031], management in peripheral DTC [32.451(4.211-250.099), p=0.001], and transferred in patients from a peripheral zone toward a 3rdor 4thDTC category [4.602(1.092-19.386), p=0.037]. Conclusion.Incidence of poor outcome of childhood TB was quite low in the North region of Cameroon. HIV, peripheral TDC and transferred in patients were predictors of poor outcome. A better management of HIV, retraining DTC personnel and early reference from peripheral DTC would reduce poor outcome among childhood TB.
