Scaling up antiretroviral therapy for HIV-infected children in Côte d'Ivoire: determinants of survival and loss to programme.

OBJECTIVE: To investigate deaths and losses to follow-up in a programme designed to scale up antiretroviral therapy (ART) for HIV-infected children in Côte d'Ivoire. METHODS: Between 2004 and 2007, HIV-exposed children at 19 centres were offered free HIV serum tests (polymerase chain reaction tests in those aged < 18 months) and ART. Computerized monitoring was used to determine: (i) the number of confirmed HIV infections, (ii) losses to the programme (i.e. death or loss to follow-up) before ART, (iii) mortality and loss-to-programme rates during 12 months of ART, and (iv) determinants of mortality and losses to the programme. FINDINGS: The analysis included 3876 ART-naïve children. Of the 1766 with HIV-1 infections (17% aged < 18 months), 124 (7.0%) died, 52 (2.9%) left the programme, 354 (20%) were lost to follow-up before ART, 259 (15%) remained in care without ART, and 977 (55%) started ART (median age: 63 months). The overall mortality rate during ART was significantly higher in the first 3 months than in months 4-12: 32.8 and 6.9 per 100 child-years of follow-up, respectively. Loss-to-programme rates were roughly double mortality rates and followed the same trend with duration of ART. Independent predictors of 12-month mortality on ART were pre-ART weight-for-age z-score < -2, percentage of CD4+ T lymphocytes < 10, World Health Organization HIV/AIDS clinical stage 3 or 4, and blood haemoglobin < 8 g/dl. CONCLUSION: The large-scale programme to scale up paediatric ART in Côte d'Ivoire was effective. However, ART was often given too late, and early mortality and losses to programme before and just after ART initiation were major problems.

Respiratory manifestations in HIV-infected children pre- and post-HAART in Abidjan, the Ivory Coast.

Among children infected with human immunodeficiency virus (HIV), respiratory diseases are a frequent cause of morbidity and mortality. This review describes respiratory manifestations of paediatric HIV infection before and after the beginning of HAART in Abidjan, Ivory Coast. In an observational cohort, HIV infected children had quarterly clinical visits and a day-clinic available all week for ill children. CD4 and viral load were measured at baseline and every 6 months thereafter. All children with a CD4 percentage below 25% were prescribed daily cotrimoxazole prophylaxis. Ninety-eight children (of a total of 282) were recruited before HAART and treated during the follow-up, there were 56 boys and 42 girls, with a mean age of 6.2 years at inclusion. The mean percentage of CD4 before HAART was 8.7%. Twelve children had a history of pulmonary tuberculosis and five were on antituberculosis treatment at inclusion. Fifty-one per cent presented with abnormalities on chest X-ray at inclusion. Before initiation of HAART, respiratory manifestations represented 32.4% of morbidity events and the incidence for 100 child/months was 9.29 for URTI, 15.2 for bronchitis, 6.07 for LRTI, 0.71 for tuberculosis and 0.36 for Pneumocystis carinii. After the initiation of HAART, respiratory manifestations represented 40.9% of all morbidity events and the incidence for 100 child/months was 5.35 for URTI, 9.48 for bronchitis, 2.17 for LRTI and 0.16 for tuberculosis. During HAART treatment, the incidence of respiratory infections decreased dramatically compared to before the antiretroviral treatment. However, respiratory events still represented 40% of all events occurring following the start of HAART therapy.
