Congenital rubella syndrome after rubella vaccination in 1-4 weeks periconceptional period.

OBJECTIVE: To examine weather exposure to rubella vaccine during 1-4 wk periconceptional period can cause congenital rubella syndrome (CRS). METHODS: This prospective study was performed in 60 pregnant women who received rubella vaccine inadvertently 1-4 wk pre or post conception. Time of conception was determined by last menstrual period (LMP) and first trimester sonography. In addition to gathering mother's obstetric and demographic information, all neonates were evaluated for CRS signs by systemic physical examination and anti rubella IgG and IgM antibody titers in cord blood samples. RESULTS: A total of 60 pregnant women with the median gestational age of 38 weeks were studied. The mean maternal age was 22 years and 58.3% of pregnancies were unintended. In 90% of mothers there were no post vaccination side effects (fever, lymphadenopathy, arthritis, arthralgia). None of the mothers had a history of drug abuse, smoking or teratogenic exposures. Mean neonatal weight was 3100grs and 6.7% of them were premature. No signs of CRS were found in the neonates based on systemic physical exam at birth and one month later. Mean value of cord blood anti rubella IgG titere was 148/28+/-67/26 lu/ml. cord blood anti rubella IgM was negative in all of the neonates. CONCLUSION: In this study inadvertent rubella vaccination 1-4 wk before and after conception did not cause CRS in neonates and according to all reasearches pregnancy termination is not indicated in these cases.

O conhecimento das gestantes sobre a síndrome da rubéola congênita / The knowledge of pregnant patients about the congenital rubella syndrome

A rubéola congênita é uma doença viral preocupante, principalmente quando acomete a gestante no primeiro trimestre gestacional. Vários estudos descrevem que a rubéola, ocorrendo precocemente na gravidez, geralmente leva a malformações congênitas variadas. A chamada Tétrade de Gregg, com alterações visuais, auditivas, cardíacas e mentais, é a mais conhecida, porém outras alterações podem ocorrer. Este trabalho mostra o grau de conhecimento das gestantes quanto aos riscos da rubéola durante a gestação e as orientações sobre o assunto recebidas do médico durante o pré-natal.

Congenital rubella syndrome in infants of women vaccinated during or just before pregnancy with measles-rubella vaccine.

BACKGROUND & OBJECTIVE: Measles and Rubella Control Campaign was conducted in Iran in December 2003 targeting both males and females 5 to 25 yr old using measles-rubella vaccine. During the campaign, some pregnant women received vaccine during the first trimester of pregnancy or some others became pregnant shortly thereafter. The goal of this study was to evaluate the risk of congenital rubella syndrome (CRS) among the infants born to the vaccinated mothers. METHODS: A total of 106 pregnant women, who had received vaccine during the first trimester of pregnancy or become pregnant less than three months after vaccination were included in the study for comparison 40 pregnant women without rubella vaccine were also included. The mothers' blood samples at the time of delivery, infants' cord blood and blood samples at the end of the second month of birth of sixty children whose parents agreed about blood sampling, were tested for rubella IgM and IgG antibodies using ELISA method. RESULTS: There were 107 live births in the exposed group and 42 in the control group. Serological study showed no IgM rubella antibody in the maternal and infant cord blood; it was not found in the second blood specimens of 60 infants tested at 8 wk of age. IgG rubella antibody was positive in all infants' cord blood but it decreased in the second blood specimens of the infants. None of the children exhibited signs of congenital rubella syndrome. INTERPRETATION & CONCLUSION: Finding of our study showed that none of the infants born to mothers vaccinated by MR vaccine during the first trimester of pregnancy or had become pregnant within three months after vaccination, had CRS.

Congenital rubella syndrome

Rubella is a major public health problem which is usually a mild rash illness in children and adults. However, its seriousness and putt health importance stems from the ability of Rubella virus to cross the placental barrier and infect fetal tissue, which may result in congenital rubella syndrome. The mechanism by which Rubella virus causes fetal damage is not well understood. Congenital rubella syndrome is an under-recognized public health problem in Pakistan and can be reduced by vaccinating all seronegative women

Síndrome de rubéola congénita en lactantes atendidos en un hospital pediátrico / Congenital rubella syndrome in infants at a pediatric hospital

Los casos de rubéola congénita en México se consideran un problema esporádico.Objetivo: Analizar y describir los hallazgos clínicos asociados a rubéola congénita (RC) en lactantes atendidos en un hospital pediátrico durante un período de ocho años (1991-1998). Material y métodos: Estudio retrospectivo. Se inclu-yeron pacientes menores de 18 meses con resultado positivo de anticuerpos IgG o lgM contra virus de rubéola, medidos por técnica de ensayo inmunoenzi-mático de micropartículas.Resultados: Se identificaron 56 casos, analizándose 42 expedientes completos; 23 fueron del sexo femenino (54.7 por ciento) y 19 del masculino (45.3 por ciento), con mediana para la edad de cinco meses (intervalo 1-14 meses). En 9/42 madres (21.4 por ciento) hubo el antecedente de exantema durante el primer trimestre del embarazo. En 15 lactantes la serología fue positiva para IgM (todos menores de cuatro meses de edad) y en 27 para IgG. Las principales alteraciones fueron oculares (74 por ciento), neurológicas (66 por ciento) y cardiopatías congénitas (67 por ciento). En 69 por ciento se detectó catarata congénita, hepatomegalia en 52 por ciento, ictericia en 43 por ciento, anemia en 40 por ciento, trombocitopenia en 48 por ciento e hipoacusia en 19 por ciento. Las alteraciones poco comunes fueron hernia umbilical, criptorquidia, hidrocele, sinostosis y neumonitis
