ABSTRACT

BACKGROUND: Intensified tuberculosis (TB) case finding and isoniazid preventive therapy (IPT) are strongly recommended for children who are HIV infected. Data are needed to assess the feasibility of the WHO 2011 intensified tuberculosis case finding/IPT clinical algorithm. METHODS: Children who are HIV infected and attending Nsambya Home Care at Nsambya Hospital, Uganda, were screened for TB following WHO recommendations. IPT was given for 6 months after excluding TB. Factors associated with time to IPT initiation were investigated by multivariate Cox proportional hazard regression. Health care workers were interviewed on reasons for delay in IPT initiation. RESULTS: Among the 899 (49% male) children with HIV, 529 (58.8%) were screened for TB from January 2011 to February 2013. Children with active TB were 36/529 (6.8%), 24 (4.5%) were lost to follow-ups and 280 (52.9%) started IPT, 86/280 (30.7%) within 3 months of TB screening and 194/280 (69.3%) thereafter. Among the 529 children screened for TB, longer time to IPT initiation was independently associated with cough at TB screening (hazard ratio 0.62, P = 0.02, 95% confidence interval: 0.41 to 0.94). Four children (1% of those starting treatments) interrupted IPT because of a 5-fold increase in liver function measurements. In the survey, Health care workers reported poor adherence to antiretroviral therapy, poor attendance to periodic HIV follow-ups, and pill burden as the 3 main reasons to delay IPT. CONCLUSION: In resource-constrained settings, considerable delays in IPT initiation may occur, particularly in children with HIV who are presenting with cough at TB screening. The good safety profile of isoniazid in antiretroviral-therapy-experienced children provides further support to IPT implementation in this population.

ABSTRACT

Correlations between clinical/immunological treatment failure and viral load (VL) detected by dried blood spot (DBS) sampling were explored in HIV-1-infected children in Uganda. Of 104 children on combined antiretroviral treatment (cART), 12.5% experienced clinical and/or immunological failure, while 28.8%, 44.2%, and 26.9% had VLs of <1,000, 1,000 to 5,000, and >5,000 copies/ml, respectively. Clinical/immunological failure poorly predicted virological failure.
