Adherence to combination antiretroviral treatment in children.

PURPOSE: To assess the level of nonadherence to combination antiretroviral therapy of HIV-infected children and to identify the main problems faced by caregivers when giving medicines to children. METHOD: A questionnaire was administered to the caregivers of HIV-infected children who were under combination antiretroviral treatment and were followed at our institution. RESULTS: We evaluated 44 children (mean age, 9.4 years); 13 were treated with a two-drug regimen, 30 with a three-drug regimen, and 1 with a four-drug regimen. Each child received a mean of 8.1 pills and/or syrup doses. In 54.5% of treatments, food restrictions were necessary. The mother was the main person giving medicines to the child (56.8%). A complete written schedule of the child's treatment was present in 50% of families. About 20.5% and 31.8% of children had missed at least one dose of antiretroviral drugs in the last 3 days before assessment and since last visit (1-2 months earlier), respectively. Main problems reported by caregivers were: (a) too many medicines/ pills (34%); (b) difficulty in swallowing pills (29.5%); (c) taking medicines at school or out of home (27.3%); (d) child resisting/refusing therapy/spitting out (25%); and (e) food interactions (22.7%). CONCLUSION: The observed high level of nonadherence was similar to what was reported by other pediatric studies. Specific interventions aimed at improving compliance in pediatric patients were identified: improvement of anti-HIV drug formulations, better counselling for children and their families, and tailoring of antiretroviral treatment. However, caution is necessary in generalizing our results due to the small sample size and to the heterogeneity of the cohort.

Comparison of an enzyme immunoassay and a latex agglutination system for the diagnosis of invasive aspergillosis in bone marrow transplant recipients.

The performance of two Aspergillus antigenemia systems, the sandwich enzyme-linked immunosorbent assay (ELISA), Platelia Aspergillus test, and the latex agglutination (LA), Pastorex Aspergillus test, in the diagnosis of invasive aspergillosis were compared by testing 364 serum samples from 22 bone marrow transplant (BMT) recipients. Sensitivity and specificity for the ELISA test were 60% and 82% respectively, vs 40% and 94% for the LA test. In the two patients found positive with both methods, the ELISA test became positive earlier than the LA test or remained positive after the LA test had become negative. These results encourage further evaluation of the Platelia Aspergillus test, to assess its role in the management of invasive aspergillosis in BMT patients.
