RESUMO
OBJETIVO: Descrever taxas de hospitalização, carga de doença e fatores de risco associados a infecções agudas respiratórias (IRAs), especialmente aquelas causadas pelo vírus sincicial respiratório (VSR) e as causadas por outros vírus, em uma coorte de pacientes menores de 2 anos com doença cardíaca congênita (DCC). MÉTODOS: Um estudo de coorte observacional e prospectivo foi realizado com pacientes com DCC que receberam alta da unidade neonatal e foram acompanhados em um centro de referência. Foram registradas variáveis demográficas, tipo de DCC e necessidades médicas. O desfecho primário foi a internação por IRA (em valores totais e referentes apenas à infecção pelo VSR e por outras causas), e o secundário a carga da doença em pacientes hospitalizados. As taxas de internação foram calculadas considerando os valores totais de IRA e também os referentes apenas à IRA pelo VSR. Também foi calculada a densidade de incidência. RESULTADOS: Foram incluídos 71 pacientes com peso de nascimento de 3.043±720 g (média ± DP); 74% necessitaram de cirurgia e 8,4% faleceram em decorrência da DCC. No total, 22/71 pacientes foram hospitalizados por IRA (31%; IC95% 20-43), 15 deles pelo VSR (21%; IC95% 12-32), e ocorreram 1,35 episódios de internação por IRA/1.000 dias de seguimento (0,92 episódios de internação por IRA causada pelo VRS/1.000 dias). Quarenta por cento dos pacientes com IRA causada pelo VSR necessitaram de admissão em UTI pediátrica, e 30% necessitaram de VM versus nenhum nos casos de IRA por outros vírus. CONCLUSÕES: Na população estudada, a internação por IRA era comum, sendo o VSR a causa mais frequente. A carga da doença associada à IRA pelo VSR foi considerável, embora nenhum paciente tivesse falecido em decorrência da IRA. Com exceção da pouca idade, nenhum outro fator de risco biológico ou social esteve associado à internação por IRA causada pelo VSR.
ABSTRACT
OBJECTIVE: To describe hospitalization rates, burden of disease, and associated risk factors of acute respiratory infections (ARI), particularly those caused by respiratory syncytial virus (RSV) and non-RSV-ARI, in a cohort of patients under 2 years of age with congenital heart disease (CHD). METHODS: A prospective, observational cohort study was conducted with CHD patients discharged from the neonatal unit and followed up at a referral center. Demographic variables, type of CHD, and medical needs were recorded. Study primary outcome was hospitalization for ARI (overall, due to RSV, and due to other causes). Secondary outcome was burden of disease in hospitalized patients. Incidence rates of hospitalization were calculated for overall ARI and RSV-ARI. Incidence densities were additionally calculated. RESULTS: Seventy-one patients with birth weight 3,043±720 g (mean ± SD) were included; 74% required surgery and 8.4% died of CHD during the study. Overall, 22/71 patients were hospitalized due to ARI (31%; 95%CI 20-43), 15 of them RSV-associated (21%; 95% CI 12-32), and there were 1.35 episodes of hospitalization for ARI/1,000 days of follow-up (0.92 episodes of hospitalization for RSV-ARI/1,000 days). Forty per cent of patients with ARI due to RSV needed admission to pediatric ICU and 30% required mechanical ventilation vs. none in non-RSV-ARI. CONCLUSIONS: In the studied population, ARI hospitalization was common, and RSV was its most frequent cause. Disease burden associated with RSV-ARI was considerable, although no patient died from ARI. Except younger age, no other biological or social risk factors were found associated with RSV-ARI hospitalization.
