This study shows that the problem of congenital syphilis is far from being solved in Brazil. It is necessary to provide adolescents with family planning services as well as guidance on sexual issues, to improve prenatal follow-up, and to research the history of sexually transmitted diseases in both the pregnant woman and her sexual partner.
Missed opportunities for congenital syphilis and HIV perinatal transmission preventionOportunidades perdidas na prevenção da sífi lis congênita e da transmissão vertical do HIV ABSTRACT OBJECTIVE: To estimate the prevalence of missed opportunities for congenital syphilis and HIV prevention in pregnant women who had access to prenatal care and to assess factors associated to non-testing of these infections. METHODS:Cross-sectional study comprising a randomly selected sample of 2,145 puerperal women who were admitted in maternity hospitals for delivery or curettage and had attended at least one prenatal care visit, in Brazil between 1999 and 2000. No syphilis and/or anti-HIV testing during pregnancy was a marker for missed prevention opportunity. Women who were not tested for either or both were compared to those who had at least one syphilis and one anti-HIV testing performed during pregnancy (reference category). The prevalence of missed prevention opportunity was estimated for each category with 95% confi dence intervals. Factors independently associated with missed prevention opportunity were assessed through multinomial logistic regression. RESULTS:The prevalence of missed prevention opportunity for syphilis or anti-HIV was 41.2% and 56.0%, respectively. The multivariate analysis showed that race/skin color (non-white), schooling (<8 years), marital status (single), income (<3 monthly minimum wages), having sex during pregnancy, history of syphilis prior to the current pregnancy, number of prenatal care visits (<6), and last prenatal visit before the third trimester of gestation were associated with an increased risk of missed prevention opportunity. A negative association with missed prevention opportunity was found between marital status (single), prenatal care site (hospital) and fi rst prenatal visit in the third trimester of gestation. CONCLUSIONS:High rates of non-tested women indicate failures in preventive and control actions for HIV infection and congenital syphilis. Pregnant women have been discontinuing prenatal care at an early stage and are failing to undergo prenatal screening for HIV and syphilis.
OBJETIVO: Determinar os fatores associados à interrupção do acompanhamento clínico ambulatorial de pacientes com infecção pelo HIV. MÉTODOS: Foi realizado um estudo do tipo prospectivo não-concorrente (coorte histórica) no município de Belo Horizonte, MG, em um ambulatório público de referência para atendimento de pacientes com infecção pelo HIV/Aids. Foram revisados registros médicos para se avaliar os fatores associados à interrupção do acompanhamento clínico por pacientes soropositivos para o HIV admitidos no serviço entre 1993 e 1995. Os pacientes deveriam ter comparecido a pelo menos uma consulta de retorno no prazo de sete meses. A análise estatística incluiu chi2 e Relative Hazard - RH com intervalo de 95% de confiança (IC) estimado pelo Modelo de Regressão de Cox. RESULTADOS: A incidência acumulada da interrupção do acompanhamento clínico foi de 54,3% entre os 517 pacientes incluídos no estudo (tempo médio de acompanhamento =24,6 meses; incidência pessoa tempo =26,5/100 pessoas-ano). A análise multivariada mostrou que realizar menos que duas contagens de linfócitos T CD4+ (RH =1.94; IC 95% =1.32-2.84) não realizar medida de carga viral (RH =14.94; IC 95% =5.44-41.04), comparecer a seis retornos ou menos (RH =2.80; IC 95% =1.89-4.14), não mudar de categoria clínica (RH =1.40; IC 95% =1.00-1.93) e não usar anti-retroviral, (RH =1.43; IC 95% =1.06-1.93) estava associado a um maior risco de interromper o acompanhamento clínico no serviço estudado. CONCLUSÕES: Foi alta a taxa de interrupção do acompanhamento clínico aos pacientes estudados, sugerindo que a interrupção do acompanhamento pode ser uma função que vise a priorizar os pacientes com pior situação clínica, podendo ser um marcador de futura aderência ao uso de anti-retroviral.
