title: [Bartonella henselae in children with regional adenitis treated in a Peruvian national hospital, 2012].
abstract: In order to determine the frequency of seropositive cases of Bartonella henselae in children with regional adenitis treated in a national hospital in Peru, a cross-sectional study was conducted in 106 children with regional adenitis greater than 1 cm in diameter. The sample was selected from patients aged 5-11 years seen at the National Institute of Child Health for acute onset of regional adentitis, with more than five days of symptoms. B. henselae seropositivity was defined by indirect immunofluorescence test. We found that 86 children (81.1%) were positive for B.henselae. The median age of the patients was 7 years. In the bivariate analysis, the following associated factors were found: aged 5 years, history of fever, lymphadenopathy greater than 4 cm and reported contact with cat. In conclusion, children with regional adenitis treated in this national referral hospital showed a high frequency of positive serology for B. henselae.
