Early manifestations of cystic fibrosis in a premature patient with complex meconium ileus at birth / Manifestações precoces da fibrose cística em paciente prematuro com íleo meconial complexo ao nascimento

OBJECTIVE: To report a case of a preterm infant with complex meconium ileus at birth and cystic fibrosis. CASE DESCRIPTION: A male infant was born by vaginal delivery at 33 weeks and 5 days of gestational age with respiratory distress and severe abdominal distension. The exploratory laparotomy in the first day of life identified meconium ileus and secondary peritonitis. Ileal resection and ileostomy were performed, followed by reconstruction of the bowel transit at 20 days of life. At 11 days of life, the first immunoreactive trypsinogen (IRT) was 154 ng/mL (reference value = 70), and oral pancreatic enzymes replacement therapy was started. After 23 days, the second IRT was 172ng/mL (reference value = 70). At 35 days of age he was discharged with referrals to primary care and to a special clinic for CF for the determination of sweat chloride. He was received in the outpatient clinic for neonatal screening for CF at 65 days of life presenting malnutrition and respiratory distress. The sweat chloride test was performed, with a positive result (126mEq/L). COMMENTS: This case illustrates the rapid evolution of CF in a premature patient with complex meconium ileus as the first clinical manifestation.

OBJETIVO: Relatar o caso de um recém-nascido prematuro com íleo meconial complexo e fibrose cística. DESCRIÇÃO DO CASO: Recém-nascido do sexo masculino nasceu de parto vaginal com 33 semanas e cinco dias de idade gestacional e apresentou desconforto respiratório e distensão abdominal grave. Foi submetido à laparotomia exploratória no primeiro dia de vida e identificado íleo meconial com peritonite secundária. Foram feitas ressecção ileal e ileostomia, com reconstrução do trânsito intestinal aos 20 dias de vida. Com 11 dias de idade, a primeira dosagem sérica de tripsina imunorreativa (TIR) foi 154ng/mL (valor de referência = 70) e optou-se pelo início da terapia de reposição oral de enzimas pancreáticas. Após 23 dias, a segunda TIR foi 172ng/mL (valor de referência = 70). Recebeu alta com 35 dias de vida com encaminhamentos à rede básica de saúde e ao serviço de referência para a detecção de fibrose cística. Foi atendido no ambulatório de triagem neonatal para fibrose cística aos 65 dias de vida e apresentava desnutrição e desconforto respiratório. O resultado do teste do cloro no suor foi positivo (126 mEq/L). COMENTÁRIOS: O caso ilustra a rápida evolução da fibrose cística em um paciente prematuro com íleo meconial complexo como primeira manifestação clínica.

Burden of group A streptococcal meningitis in Salvador, Brazil: report of 11 years of population-based surveillance.

BACKGROUND: Over recent decades, a resurgence of invasive group A streptococcal (GAS) infections has been observed; GAS remains a rare cause of pyogenic meningitis. We report herein population-based findings of long-term surveillance for GAS meningitis in Salvador, Brazil, and estimate the overall burden of invasive GAS infections. METHODS: From February 1996 to February 2007 we conducted active surveillance for GAS meningitis in the state reference hospital for infectious diseases in Salvador, Brazil. Data on clinical presentation, laboratory records, and outcome were collected through interviews and chart review. GAS isolates were evaluated for antimicrobial susceptibility and emm type. RESULTS: We identified 20 cases of GAS meningitis, which accounted for 0.9% of all culture-proven bacterial meningitis in the study period. The mean annual incidence of GAS meningitis was 0.03 cases per 100,000 population in metropolitan Salvador and peaked in children <1 year of age (0.67 cases per 100,000 population). Among 17 cases with clinical information available, 41% required intensive care unit support and 25% died. Tested isolates were susceptible to penicillin and exhibited large emm type diversity. Based on the incidence of GAS meningitis, we estimate that the annual incidence of GAS infection is 3 cases per 100,000 population in metropolitan Salvador. CONCLUSIONS: Although rare, GAS is a life-threatening cause of bacterial meningitis. Knowledge of the incidence and emm type variability of the disease is necessary for planning immunization strategies.
