ABSTRACT

OBJETIVO: Relatar um caso de meningoencefalite, provavelmente causada pelo vírus vacinal da febre amarela transmitido pelo leite materno. DESCRIÇÃO: Paciente de 38 dias de idade, internado em 23/05/09 para investigação de febre. No dia 25/05/09 iniciaram-se as crises convulsivas. O exame do líquido cefalorraquidiano (LCR) foi sugestivo de meningoencefalite. A mãe havia recebido dose da vacina contra febre amarela e o bebê estava em aleitamento materno exclusivo. Recebeu alta com controle das crises convulsivas. Foi detectado anticorpo IgM específico para febre amarela no soro e no LCR. COMENTÁRIOS: Em 2009, ocorreu o primeiro caso confirmado de meningoencefalite pelo vírus vacinal da febre amarela transmitido pelo leite materno. Descrevemos o segundo caso, em que, possivelmente, o vírus vacinal tenha sido o agente etiológico da meningoencefalite. O Ministério da Saúde do Brasil recomenda adiar a vacinação de nutrizes até a criança completar 6 meses ou orientar alternativas para evitar o risco de transmissão do vírus vacinal pelo leite materno.


OBJECTIVES: To describe a case of infant meningoencephalitis that was probably caused by yellow fever vaccine virus transmitted via breastmilk. DESCRIPTIONS: A 38-day old patient was admitted to hospital on May 23, 2009, with fever. On May 25, 2009, convulsive crises began. Cerebrospinal fluid (CSF) test results were suggestive of meningoencephalitis. The mother had been given a dose of yellow fever vaccine and the baby was on exclusive breastfeeding. The baby was discharged after the convulsive crises were controlled. Tests identified IgM antibodies specific for yellow fever in both serum and CSF. COMMENTS: In 2009, the first case was confirmed of meningoencephalitis caused by the yellow fever vaccine virus transmitted via breastmilk. We describe a second case in which the vaccine virus was possibly the etiologic agent of meningoencephalitis. The Brazilian Ministry of Health now recommends delaying vaccination of nursing mothers until their children reach 6 months or providing them with guidance on alternative options to avoid the risk of transmission of the vaccine virus via breastmilk.
