ABSTRACT

OBJECTIVE: To evaluate the role of docosahexaenoic acid (DHA) administered during the acute phase of pneumonia in infants, on appetite, cytokines and leptin concentrations. METHODS: Seventeen children between three months and 12 years of age were followed from hospitalization to discharge. Children were randomly assigned to receive DHA or placebo. The effect of treatment was evaluated on energy intake, cytokines, and leptin concentrations. RESULTS: Cytokine concentrations tended to decrease earlier in DHA children. By day 4, concentrations of IL-1beta and TNFalpha had decreased by 12%, while such concentrations increased by 12% and 250% in placebo children. Energy intake recovered in DHA children at discharge, but placebo children were still consuming only 60% of their requirements. CONCLUSIONS: Our results suggest that DHA administered in the acute phase of infection could modulate IL-1 and TNF production, and secondarily, decrease the effect of infection on appetite.

ABSTRACT

La infección urinaria es frecuente durante el embarazo; la Escherichia coli es el patógeno más común, seguido por Klebsiella pneumoniae, diferentes tipos de Enterobacter, estreptococos y estafilococos. La ampicilina ha sido ampliamente usada como primera elección, sin embargo, la resistencia bacteriana a este antibiótico es alta. Objetivo: determinar el perfil de resistencia microbiana para los gérmenes más frecuentemente implicados en la infección de vías urinarias durante el embarazo. Metodología: se estudiaron los resultados de urocultivo y antibiograma realizados a mujeres embarazadas, en un periodo de 15 meses desde enero de 2004 hasta abril de 2005. Resultados: un total de 45 pacientes tuvieron urocultivo positivo. El germen más frecuentemente aislado fue Escherichia Coli eun un 64 por ciento, seguido de Klebsiella pneumoniae, con un porcentaje de resistencia de Escherichia Coli a la ampicilina del 82 por ciento y a la gentamicina del 3 por ciento.
