Transmissão vertical do HIV em população atendida no serviço de referência / Vertical transmission of HIV in the population treated at a reference center

RESUMO

OBJETIVO: Identificar a taxa de transmissão vertical do HIV e avaliar os fatores envolvidos em partes materna e fetal. MÉTODOS: Estudo transversal realizado no Serviço de Atendimento Especializado. Foram investigados 102 prontuários de mulheres com HIV que deram à luz a recém-nascidos vivos. RESULTADOS: A prevalência de 6,6% de transmissão vertical. Entre as crianças infectadas 40,0% de mães sem pré-natal e 75% sem a profilaxia com anti-retrovirais durante o pré-natal, 50,0% sem profilaxia com AZT com oral e amamentado. Entre as crianças não infectadas 91,5% iniciaram a profilaxia com AZT oral ao nascimento e 84,1% das mães receberam ARV. CONCLUSÃO: A ocorrência de transmissão vertical do HIV no serviço de referência correspondeu a 6,6%, o que indica uma alta prevalência.

ABSTRACT

OBJECTIVE: To identify the rate of vertical transmission of HIV and assess the factors involved in maternal and fetal share. METHODS: Cross-sectional study conducted in the Specialized Care Service. We investigated 102 clinical records of HIV positive women who had given birth to live newborns. The primary variable was the occurrence of vertical transmission of HIV and the secondary variables were the factors associated with vertical transmission of HIV. RESULTS: Prevalence of 6.6% of vertical transmission. Among the infected children 40.0% of mothers with out prenatal care and 75% without prophylaxis with antiretroviral drugs during the prenatal, 50.0% without AZT prophylaxis with oral and breast-fed. Among the uninfected children 91.5% were started on prophylaxis with oral AZT at birth and 84.1% of mothers received ARV delivery. CONCLUSION: The occurrence of vertical transmission of HIV in the reference service corresponded to 6.6%, indicating a high prevalence.
