| English abstract | Chlamydia trachomatis infection is adquired by the newborn infant during the delivery, 25 to 50 % of them may develop conjunctivitis and 10 to 20 % pneumonia. BACKGROUND: To verify the incidence of ocular infection by C. trachomatis in the newborn infants with conjunctivitis. To observe the association between ocular infection and intersticial pneumonia.-Study the epidemiological aspects and laboratorial methods of criterial diagnosis. CASUISTICS AND METHODS: We studied the newborn infants admitted in the intensive neonatal care with diagnostic of conjunctivitis and/or interstitial pneumonia during the period of ten years. The diagnostic methods were direct exam of etiologic agent in conjunctival material, X ray chest and serologic test by imunofluorescence method for IgG and IgM antibodies. RESULTS: We studied the clinical characteristics of 20 newborns infants with chlamydial trachomatis infection: 15 (75%) were terms newborns and 5 (25%) pre-terms. We observed the predominance of infection in females (60%); pneumonia was observed in 15/20 (75%) and 12 of them had both: conjunctivitis and pneumonia. we did not observe significant association among type of delivery, age of the mother, number of partner and infection. Leukorrhea was present em 50% of the mothers The serologic test was positive in 100% of the newborn with pneumonia and none with conjunctivitis alone,and the direct exam in conjuntival material was positive in newborns with conjunctivitis. The incidence of C. trachomatis in the newborns admitted in this period with conjunctivitis were 17/100 (17%). CONCLUSION: Chlamydia trachomatis is an important pathogenical agent and the research of it is essential in newborn infants with conjunctivitis and/or interstitial pneumonia even there were not risk factors for sexually transmitted diseases. The direct exam of conjunctival material and serologic test are very important to diagnosis |
| Portuguese abstract | A infecção por C. trachomatis é adquirida pelo recém-nascido (RN) principalmente durante sua passagem pelo canal do parto; 25% a 50% destes deverão desenvolver conjuntivite e 10% a 20% pneumonia. OBJETIVOS: Verificar a incidência de infecção ocular por C. trachomatis nos RN internados com diagnóstico de conjuntivite, num período de 10 anos. - Observar a associação entre infecção ocular é pneumonia intersticial - Estudar os aspectos epidemiológicos e os métodos utilizados para o diagnóstico laboratorial. CASUÍSTICA E METODOLOGIA: Foram analisados os RN internados com diagnóstico de conjuntivite e/ou pneumonia intersticial internados na UCINE no período de 1987-1998. Os métodos de diagnóstico utilizados foram: a pesquisa direta do agente etiológico em raspado de conjuntiva, radiografia de tórax, sorologia para C. trachomatis no sangue pelo método de imunofluorescência para anticorpos IgG e IgM. RESULTADOS: Estudamos as características de 20 RN que apresentaram infecção por C. trachomatis : 15 eram de termo (75%) e cinco, pré-termos (25%); houve predominância da infecção no sexo feminino (60%); a pneumonia esteve presente em 15 dos 20 RN (75%) e 12 apresentaram associação de conjuntivite e pneumonia. Não houve relação significante entre tipo de parto, idade materna, número de parceiros e a infecção, sendo que o antecedente materno de leucorreia esteve presente em 50% dos casos. O diagnóstico sorológico esteve relacionado com a presença de pneumonia e a pesquisa direta com a conjuntivite. A incidência de conjuntivite por C. trachomatis |
