    We measured IgA and IgG antibodies to pertussis toxin (PT) and filamentous hemagglutinin (FHA) in sera from 203 1-year-old children who had received one to three doses of a monocomponent PT toxoid vaccine. Ten children (5%) had IgA antibody to PT indicating recent infection; seven of these children had received three doses of vaccine. PT IgA responders did not have significantly longer coughing episodes than PT IgA non-responders. Since an IgA antibody response occurs in only ∼50% of infected children, the actual infection rate in our cohort is estimated to ∼10%. The apparent high Bordetella pertussis infection rate in Danish infants suggests that the monocomponent PT toxoid vaccine used in Denmark has limited efficacy against B. pertussis infection. A prospective immunization study comparing a multi-component vaccine with the present monocomponent PT toxoid vaccine should be undertaken

    Neonatal Hepatitis as First Manifestation of Hyperimmunoglobulinemia D Syndrome

    Hyper IgD syndrome (HIDS) is a rare metabolic autoinflammatory syndrome characterised by recurrent febrile episodes, accompanied by various inflammatory symptoms. We present a case of severe HIDS in a young girl, whose symptoms started in the neonatal period with hepatomegaly, hepatitis, thrombocytopenia, and conjugated hyperbilirubinemia. From the age of five months, the child had recurrent febrile episodes, stomatitis, adenitis, and persistent hepatomegaly. The diagnosis of HIDS was established when she was three years and eight months old. This case report suggests that HIDS should be included in the differential diagnosis of neonatal hepatitis and conjugated hyperbilirubinemia

    Antimicrobial Susceptibility among Gram-Negative Isolates in Pediatric Patients in Europe from 2013-2018 Compared to 2004-2012: Results from the ATLAS Surveillance Study

    Aims: Data on antimicrobial resistance (AMR) in the paediatric patient population are scarce. This study assessed the AMR rates and phenotype distribution of Gram-negative isolates in paediatric patients in Europe from 2004-2012 and 2013-2018. Methods: Isolates that were collected were stratified by age groups ( < 1, 1-5, 6-12, and 13-17 years) and regions (North-Western, Eastern and Southern Europe). Minimal inhibitory concentrations (broth microdilution) were interpreted according to European Committee on Antimicrobial Susceptibility Testing guidelines. Resistance rates and phenotype prevalence were identified for Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, Acinetobacter baumannii, Pseudomonas aeruginosa , and Haemophilus influenzae . Results: In the overall paediatric patient population (0-17 years), extended-spectrum beta-lactamase (ESBL) production significantly decreased (from 20.7% to 15.4%, P < 0.0 0 01) in Escherichia coli , whereas it increased for Klebsiella pneumoniae (from 35.0% to 39.2%, P = 0.015). Carbapenem resistance was highest for Acinetobacter baumannii (32.3%) compared with Klebsiella pneumoniae (4.7%) and Pseudomonas aeruginosa (12.4%) in 2013-2018, and rates were significantly increased relative to 2004-2012. There was no change in resistance to beta-lactam antimicrobials for Haemophilus influenzae. The lowest resistance rates for most organism groups were observed in North-Western Europe. Conclusions: The results revealed a significant increase in Klebsiella pneumoniae isolates with an ESBL and carbapenem-resistance phenotype as well as in carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa from 2004-2012 to 2013-2018. Conversely, a decrease in ESBL E. coli was observed. Continued surveillance and awareness of resistance in these bacteria causing serious infections is crucial for improving treatment quality in paediatric patients.

    Barriers for vaccination of healthcare workers

    No full text
    Outbreaks of vaccine preventable diseases (VPDs) in hospital settings remain a challenge even in countries with established (childhood-) vaccination programs. Healthcare workers (HCWs) with an updated vaccination card play an important role in reducing the risk of nosocomial spread of VPDs. Yet, in many places, HCWs report their immunization status to be unknown or not updated. In times of a global pandemic, the debate on vaccination of HCWs is as hot as ever; do HCWs have an increased responsibility to get vaccinated against VPDs? If so, how do we increase vaccination uptake rates among HCWs? Mandatory vaccination against VPDs for HCWs has been introduced in some countries, but it may cause ethical dilemmas and not be culturally acceptable everywhere. We looked at vaccination policies and HCWs’ attitudes toward immunization against VPDs. We found that missing vaccine policies and lack of knowledge of VPDs, vaccination benefits, as well as inadequate organization around HCWs’ immunizations were important barriers to have a complete vaccination record. A systematic approach to employees providing information of VPDs and vaccinations, going through their vaccination cards and offering antibody testing where appropriate or a shot of a missing vaccine could support staff to adhere to vaccination schemes
