[Risk factors for sporadic cases of Campylobacter infection in children]. / Factores de riesgo de casos esporádicos de gastroenteritis por Campylobacter en niños.

OBJECTIVES: To identify risk factors for sporadic cases of Campylobacter infection in children aged 14 years. METHODS: We performed an age-matched, case-control study. Cases were residents of Lleida Health Region aged 6 months to 14 years old with diarrhea and positive stool isolation for Campylobacter. Information was gathered by telephone using a structured questionnaire on individual susceptibility and food and non-food exposures. A multivariate conditional logistic regression model was used to estimate adjusted odds ratios (ORa) and their 95% confidence intervals (95%CI). RESULTS: Forty-five cases and 45 controls were included in the analysis. The median age of cases was 1.6 years. Factors independently associated with disease were consumption of cooked deli meat 2 times (ORa:4.2, 95%CI:1.2-14.7), chicken 3 times (ORa:3.6, 95%CI:1.1-11.1) in the week before symptom onset, and previous antibiotic intake (ORa:4.7, 95%CI:1.1-19.6). CONCLUSIONS: Chicken meat was a risk factor for sporadic cases of campylobacteriosis in children, whether through consumption or through cross-contamination with other <> foods such as cooked deli meat.

ObjetivosIdentificar factores de riesgo en casos esporádicos de gastroenteritis por Campylobacter en niños <14 años de edad.MétodosEstudio de casos y controles emparejados por edad. Los casos eran residentes de la región sanitaria de Lleida de 6 meses-14 años con diarrea y aislamiento de Campylobacter. Se recogió información telefónicamente mediante cuestionario estructurado sobre predisposición individual, exposiciones alimentarias y no alimentarias. Mediante multivariado de regresión logística condicional se estimó la odds ratio ajustada (ORa) y el intervalo de confianza del 95% (IC95%).ResultadosSe incluyeron 45 casos y 45 controles. La edad mediana de los casos fue de 1,6 años. El consumo de fiambre ⩾2 veces (ORa:4,2; IC95%:1,2–14,7), pollo ⩾3 veces (ORa:3,6; IC95%:1,1–11,1) y toma previa de antibióticos (ORa:4,7; IC95%:1,1–19,6) se asociaron independientemente con la enfermedad.ConclusionesSe identificó la carne de pollo como factor de riesgo de campilobacteriosis, bien por consumo o por manipulación inadecuada que podría ocasionar contaminación cruzada de otros alimentos «listos para comer», como los fiambres(AU)
