RESUMEN
El Haemophilus influenzae (Hi) causa enfermedad invasiva (EI). Se distinguen cepas capsuladas, como el serotipo b (Hib), y cepas no tipificables (HNT). Al año de declarada la pandemia por COVID-19, observamos un aumento de casos. Se describen las características clínico-epidemiológicas de niños con EI por Hi internados en el hospital (julio 2021-julio 2022). Hubo 14 casos; 12 previamente sanos. Aislamientos Hib (n = 6), Hi serotipo a (n = 2), HNT (n = 5), 1 no se tipificó. Mediana de edad 8,5 meses (RIC 4-21). Manifestaciones meningitis (n = 5), neumonía (n = 6), celulitis (n = 2), artritis (n = 1). Nueve presentaron vacunación incompleta para Hib. Observamos un incremento de EI por Hi de 2,5 veces respecto a años previos. Estos datos sugieren el resurgimiento de Hib por la caída de las coberturas de vacunación y porque otras cepas de Hi no b están en aumento.
ABSTRACT
Haemophilus influenzae (Hi) causes invasive disease. There are encapsulated strains, such as serotype b (Hib), and non-typeable strains (NTHi). One year after the outbreak of the COVID-19 pandemic, the number of cases increased. In this report we describe the clinical and epidemiological characteristics of children hospitalized with invasive Hi disease (July 2021-July 2022). There were 14 cases; 12 were previously healthy children. Isolations Hib (n = 6), Hi serotype a (n = 2), NTHi (n = 5); 1 case was not typified. Median age 8.5 months (IQR 421). Manifestations meningitis (n = 5), pneumonia (n = 6), cellulitis (n = 2), arthritis (n = 1). Incomplete Hib immunization was observed in 9 children. Invasive Hi disease increased 2.5 times from previous years. These data suggest the reemergence of Hib due to a decline in vaccination coverage and an increase in other non-b-type Hi serotypes.
