title: Nineteen-years of pneumococcal invasive disease surveillance in a children's hospital in Mendoza, Argentina.
abstract: Five hundred and thirty-seven children admitted to Hospital Dr. Notti and diagnosed with invasive pneumococcal disease between 1993 and 2011 were studied. Their median age was 19 months (range= 0-192 months); 34.82% were <1 year old and 23.46%, >60 months old. Pneumonia with or without effusion (48.04%) and meningitis (29.05%) were the most predominant conditions, with a case fatality rate of 6.14%. Identified serotypes corresponded to 14, 5 and 1 in56.86% of cases. Sensitivity to penicillin was observed in99.74% of non-meningeal strains, while sensitivity to ceftriaxone was found in 98.08% ofmeningeal strains. Risk factors inpneumonia with effusionwere associated to age >60 months old, RR: 1.47 (1.06-2.04), p= 0.02, to serotype 5, RR: 2.57 (1.71-3.87), p= 0.0001, and to serotype 1, RR: 1.86 (1.17-2.96), p= 0.014; in the case of meningitis, risk factors were mainly associated to age <1 year old, RR: 2.35 (1.87-3.06), p= 0.0000, and to serotype 18C, RR: 2.19 (1.3-3.7), p= 0.024. Conclusion. Streptococcus pneumonia was a major problem in infants younger than one year old, who predominantly developed meningitis which caused half of deaths, and in children older than 60 months old, who had a prevalence of pneumonia with effusion. Most cases were sensitive to penicillin and ceftriaxone.
