ABSTRACT

Resumen La peritonitis por neumococo comprende un pequeno subconjunto de pacientes con enfermedad invasiva (ENI). Durante 15 años (2005-2020) de vigilancia de ENI en un hospital de pediatría, se detectaron 5 casos de peritonitis primaria. Los pacientes, 3 ninas y 2ninos con una media de edad de 5 anos, experimentaron signos y síntomas peritoneales; 3 de ellos presentaban síndrome nefrótico. En coincidencia con los perfiles locales, todos los aislamientos fueron sensibles a betalactámicos, una cepa expresó resistencia a tetraciclina y cotrimoxazol y otra solo a cotrimoxazol. Los serotipos encontrados en 4/5 cepas (una resultó no viable) fueron 1, 19F, 15C y 23A. Los ninos fueron tratados con cefalosporinas de tercera generación o con ampicilina, gentamicina y metronidazol; todos evolucionaron favorablemente. Se destaca la importancia del hallazgo de Streptococcus pneumoniae en peritonitis primarias en niños. Este trabajo contribuye al conocimiento de esta enfermedad en particular y al de la epidemiología local de la ENI.


Abstract Pneumococcal peritonitis represents a small subset of patients suffering from inva-sive pneumococcal disease (IPD). We describe 5 cases of primary peritonitis documented in the pediatric hospital over 15 years (2005-2020) of IPD surveillance. The patients, 3girls and 2boys with a mean age of 5 years, experienced peritoneal signs and symptoms; 3of them suffered from nephrotic syndrome. Based on the local resistance profiles, all isolates were sensitive to beta-lactams, one strain showed resistance to cotrimoxazole and tetracycline while another strain, to cotrimoxazole only. Serotypes found in 4/5 strains (one was non-viable) were: 1, 19F, 15C and 23A. Children were treated with third-generation cephalosporins or ampicillin, gentamicin and metronidazole and all of them evolved favorably. Pneumococcal etiology should be included in the differential diagnosis of acute abdominal pain in children. Our study aims to contribute to the knowledge of this condition and to the local epidemiology of IPD.
