Objective: To evaluate HAART-associated changes in growth and hospitalization rates over time in a cohort of HIV-infected children. Methods:Children starting HAART were assessed during the first 3 years of therapy. Clinical response was assessed every 24 weeks by z scores of weight-for-age and height-for-age. Linear regression models were used to detect predictors of clinical response. Pertinent information on hospitalizations was obtained retrospectively through review of medical records.Results: A total of 196 children were assessed. Mean weight z score increased from -1.62 (±1.32) at baseline to -1.14 (±1.12) by week 24. Mean height z score increased from -1.88 (±1.45) at baseline to -1.66 (±1.18). Better z scores at baseline were associated with greater increases in weight z scores over time. Lower viral load and higher height z scores at baseline were also associated with improved height catch-up. Eighty-five children (43.3%) were hospitalized. Most hospitalizations were prompted by infectious disease, with only two due to opportunistic infections. Conclusion:HAART was associated with significant increases in weight and height z scores. Younger age, the use of protease inhibitors and advanced clinical disease were associated with better outcomes. The present study demonstrated the effectiveness of HAART in significantly reducing hospitalization, death, and incidence of opportunistic infections among HIV-infected children.J Pediatr (Rio J). 2011;87(2):131-137: HIV, child, body weight, height, HAART. ResumoObjetivo: Avaliar mudanças em parâmetros de crescimento e hospitalização em crianças infectadas pelo vírus da imunodeficiência humana (human immunodeficiency virus, HIV) em uso de terapia antirretroviral combinada. Métodos:As crianças foram avaliadas durante os primeiros 3 anos de terapia. A resposta clínica foi avaliada a cada 24 semanas com base em escores z de peso/idade e altura/idade. Modelos de regressão linear foram utilizados para identificar preditores de resposta clínica. Dados relevantes relativos à hospitalização dos pacientes foram obtidos retrospectivamente mediante revisão dos prontuários clínicos.Resultados: Um total de 196 crianças foram avaliadas. A média do escore z aumentou de -1,62 (±1,32) no início do estudo para -1,14 (±1,12) na semana 24. A média do escore z de altura/idade aumentou de -1,88 (±1,45) para -1,66 (±1,18). Foi observada associação entre maiores escores z no início do estudo e maiores aumentos nos escores z de peso/idade ao longo do tempo. Cargas virais mais baixas e escores de altura/idade mais altos também estiveram associados com maior recuperação do crescimento. Oitenta e cinco crianças (43,3%) foram hospitalizadas. A maioria das internações esteve associada a causas infecciosas, sendo apenas dois casos de infecções oportunistas. Conclusão:A terapia combinada resultou em aumentos significativos nos escores z de peso/idade e altura/idade. A menor idade, o uso de inibidores de protease e a classificação clínica em estágios avançados estiveram associados a uma ma...
