Streptococcus pneumoniae (pneumococcus) is responsible for serious pediatric respiratory infections, and kills close to one million children under the age of five each year. Unfortunately, the Prevnar-13 vaccine (PCV-13) that is used to protect children from the serious consequences of pneumococcus infections is not always successful. Given that vitamin A deficiency (VAD) is known to affect children in both developed and developing countries, we asked if VAD could be responsible, at least in part, for PCV-13 vaccine failures...

INTRODUCTION: Pertussis causes the highest complication rates and deaths in the infant group. Our study explored risk factors for ICU/high dependency (HD) admissions and intubation/non-invasive ventilation (NIV). METHODS: A retrospective review of pertussis admissions over 10 years from 2007 to 2016 was done at KK Women's and Children's Hospital, Singapore. To understand risk factors for severe pertussis infection, we compared cases requiring ICU/HD care with controls admitted to the general ward...

Background: Influenza causes substantial morbidity in children worldwide, although influenza vaccine is seldom used in low-resource settings. More information on the clinical presentation of influenza and the efficacy of vaccine is needed to inform policy. Methods: In 2013 we conducted a randomized, placebo-controlled clinical trial of live attenuated influenza vaccine (LAIV) in children aged 24-59 months in Bangladesh (N = 1761). If participants met prespecified specimen collection criteria, we collected nasopharyngeal washes for testing by singleplex reverse-transcription polymerase chain reaction (RT-PCR) for laboratory-confirmed influenza virus infection (LCI)...

BACKGROUND: Community-acquired pneumonia (CAP) is a major cause of childhood morbidity and mortality worldwide. The angiotensin-converting enzyme (ACE) gene is a potential candidate gene for CAP risk. OBJECTIVES: In this study, we aimed to investigate whether the ACE insertion/deletion (I/D) polymorphism (rs4340) could be a genetic marker for CAP susceptibility in Egyptian children, and we also measured the serum ACE level to assess its relation to such polymorphism...

The measurement of antibody levels is a common test for the diagnosis of Streptococcus pneumoniae infection in research. However, the quality of antibody response, reflected by avidity, has not been adequately evaluated. We aimed to evaluate the role of avidity of IgG against eight pneumococcal proteins in etiologic diagnosis. Eight pneumococcal proteins (Ply, CbpA, PspA1 and 2, PcpA, PhtD, StkP-C, and PcsB-N) were used to develop a multiplex bead-based avidity immunoassay. The assay was tested for effects of the chaotropic agent, multiplexing, and repeatability...

Question Among young children suffering from pneumonia, zinc deficiency has been documented in many countries. Is supplementation with zinc effective in the treatment and prevention of childhood pneumonia? Answer Several studies reported that zinc supplementation for more than 3 months was effective for preventing pneumonia in children younger than 5 years of age; however, the evidence is not sufficient to confirm its prophylactic properties if it is given for shorter periods of time. Adjunctive zinc supplementation for treatment of pneumonia has failed to show a benefit...

In the last years, there has been a tremendous increase in the incidence of bacterial infections due to resistant strains, especially multi-drug resistant Gram-negative bacilli. In Europe, a north to south and a west to east gradient was noticed, with more than one third of the K. pneumonia isolates being resistant to carbapenems in few countries. New antibiotics are lacking and, as a consequence, pharmacokinetic/pharmacodynamic parameters, normalized to pathogen minimal inhibitory concentration, are used with increased frequency to treat infections due to difficult-to-treat pathogens...

Early distinction between severe Mycoplasma pneumoniae pneumonia (MPP) and mild MPP is still difficult. The aim of this study was to analyze cytokines in bronchoalveolar lavage fluid (BALF) and explore predicting factors of severe MPP in children. Retrospective analysis was performed on 150 children with MPP or bronchial foreign body (FB) admitted in our hospital. The mRNA levels of IL17A were found significantly lower in severe MPP group comparing with mild MPP group or FB group. However, no significant difference was found in the levels of IL4, IL10 or interferon beta1 (IFNβ1) between the two groups...

Zohra S Lassi, Aamer Imdad, Zulfiqar A Bhutta
BACKGROUND: Pneumonia is a leading cause of childhood mortality from infectious disease, responsible for an estimated 1.3 million deaths annually in children under five years of age, many of which are in low-income countries. The World Health Organization recommends intravenous antibiotics for five days as first-line treatment for children with severe pneumonia. Although controversy exists regarding the specific clinical features used to diagnose pneumonia, the criteria for diagnosis of severe pneumonia are better defined and are widely used to triage children for referral and second-line therapy...
