The aim of this study was to evaluate the prevalence of nasopharyngeal (NP) carriage and the serotype distribution and antimicrobial resistance of Streptococcus pneumoniae in children with chronic diseases, which predisposes them to invasive pneumococcal disease in comparison with that in healthy children. A cross-sectional prevalence study was performed between February 2015 and February 2016 in Istanbul, Turkey. We enrolled 1,024 children with chronic diseases and 394 healthy children aged 0-18 years. The overall prevalence of S. pneumoniae NP (SPNP) carriage was 9.8%, with 8.4% in healthy children and 10.3% in children with chronic diseases. The prevalence rates of SPNP carriage were 17.5%, 13.5%, 10.5%, 9.3%, 8.6%, 8.6%, 8%, 6.7%, and 4%, respectively, in each of the following risk groups: primary immunodeficiency, asthma, chronic renal failure, congenital heart disease, chronic lung disease, leukemia, nephrotic syndrome, solid organ tumors, and type 1 diabetes mellitus. In the multivariate analysis, a history of otitis media within the last year, a history of pneumonia within the last year, and more than one sibling under 8 years of age were found to be independent risk factors for SPNP carriage.
