Background: Patients with nephrotic syndrome (NS) are at a higher risk of developing invasive pneumococcal disease (IPD). Pneumococcal carriage studies are helpful tools for detecting potentially infectious serotypes and guiding immunization efforts. Pneumococcal nasopharyngeal colonization is common, and IPD can easily occur in an immunosuppressed state.

Respiratory tract infections are among the most important causes of mortality and morbidity in children worldwide. The COVID-19 pandemic has affected the distribution of seasonal respiratory viruses as in all areas of life. In this study, we have aimed to evaluate the changes in the rates of seasonal respiratory viruses with the onset of the pandemic.

Article Synopsis
  • Pregnant women in countries without pertussis vaccination during pregnancy need to assess their antibody levels to inform immunization strategies.
  • In a study of 396 pregnant women, various levels of pertussis antibodies were measured in both maternal and cord blood, revealing a high prevalence of low antibody levels.
  • Despite the serious risks pertussis poses to infants, the study highlights a significant gap in vaccination rates and subsequent antibody presence in pregnant women.

Introduction: Lower respiratory tract infections are the leading cause of morbidity and mortality in children worldwide. It is crucial to promptly conduct diagnostic investigations in order to determine the microbiological cause of pneumonia, since this is necessary to ensure the appropriate delivery of antibiotic therapy to each individual patient. We evaluated the results of a rapid molecular diagnostic pneumonia panel in children with LRTI in a pediatric intensive care unit (PICU).

Article Synopsis
  • The study investigates multisystem inflammatory syndrome in children (MISC) related to COVID-19, focusing on comparing clinical and laboratory characteristics of children hospitalized in ICU versus those who were not.
  • Conducted from June 2021 to January 2022, the observational study included 601 patients, with 157 requiring ICU care, revealing significant differences in demographics, lab results, and disease features.
  • Key findings showed that older age groups and higher levels of certain inflammatory markers increased the likelihood of ICU admission, highlighting the severe impact of MISC on children's health.

This multi-center point prevalence study evaluated children who were diagnosed as having coronavirus disease 2019 (COVID-19). On February 2nd, 2022, inpatients and outpatients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were included in the study from 12 cities and 24 centers in Turkey. Of 8605 patients on February 2nd, 2022, in participating centers, 706 (8.

Introduction: Acute gastroenteritis is one of the most common causes of hospital admission in children. Treatment regimens differ depending on the pathogen. In our study, we aimed to evaluate the epidemiological and clinical features of pediatric patients whose gastrointestinal agents were detected by multiplex PCR.

Background: The aim was to evaluate the epidemiological, clinical, laboratory, and radiologic data of children with SARS-CoV-2 positivity by polymerase chain reaction (PCR) together with treatment strategies and clinical outcomes and to evaluate cases of multisystem inflammatory syndrome in children (MIS-C) in this population.

Methods: This was a multicenter retrospective observational cohort study performed in the pediatric emergency departments of 19 tertiary hospitals. From March 11, 2020, to May 31, 2021, children who were diagnosed with confirmed nasopharyngeal/tracheal specimen SARS-CoV-2 PCR positivity or positivity for serum-specific antibodies against SARS-CoV-2 were included.

Unlabelled: Microbiota composition may play a role in the development, prognosis, or post-infection of COVID-19. There are studies evaluating the microbiota composition at the time of diagnosis and during the course of COVID-19, especially in adults, while studies in children are limited and no study available in children with multisystem inflammatory syndrome in children (MIS-C). This study was planned to compare intestinal microbiota composition in children diagnosed with MIS-C and acute COVID-19 infection with healthy children.

Meningococcal carriage studies and transmission modeling can predict IMD epidemiology and used to define invasive meningococcal disease (IMD) control strategies. In this multicenter study, we aimed to evaluate the prevalence of nasopharyngeal ( carriage, serogroup distribution, and related risk factors in Turkey. Nasopharyngeal samples were collected from a total of 1267 children and adolescents and were tested with rt-PCR.
