Background: Pertussis causes severe disease in young unvaccinated infants, with preterms potentially at highest risk. We studied pertussis in hospitalized infants as related to gestational age (GA) and vaccination history.
Methods: Medical record data of 0-2y old patients hospitalized for pertussis during 2005-2014 were linked to vaccination data.
Background: Maternal tetanus, diphtheria, and acellular pertussis (Tdap) vaccination offers protection for neonates against clinical pertussis until primary vaccinations, but maternal antibodies also interfere with infants' immune responses to primary vaccinations. We investigated the effect of maternal Tdap vaccination on the pertussis antibody responses of infants starting primary vaccinations at age 3 months.
Methods: In an open-label, parallel, randomised, controlled trial, pregnant women aged 18-40 years with a low risk of pregnancy complications were recruited through independent midwives at 36 midwife clinics in the Netherlands and received Tdap vaccination either at 30-32 weeks of pregnancy (maternal Tdap group) or within 48 h after delivery (control group).
Background: The aim of this study is to establish asthma knowledge of parents of children (0-18 years) with asthma at the outpatient clinic.
Methods: A translated and adapted a 21 item Likert type 5 point scale questionnaire (Cronbach's α-coefficient 0.73) was completed by 291 parents of children with asthma.
Background: The relation between viral load and disease severity in childhood acute respiratory tract infections (ARI) is not fully understood.
Objectives: To assess the clinical relevance of the relation between viral load, determined by cycle threshold (CT) value of real-time reverse transcription-polymerase chain reaction assays and disease severity in children with single- and multiple viral ARI.
Study Design: 582 children with ARI were prospectively followed and tested for 15 viruses.
