BACKGROUND: GSK has modified the licensed monovalent bulk manufacturing process for its split-virion inactivated quadrivalent influenza vaccine (IIV4) to harmonize the process among different strains, resulting in an increased number of finished vaccine doses, while compensating for the change from inactivated trivalent influenza vaccine (IIV3) to IIV4. To confirm the manufacturing changes do not alter the profile of the vaccine, a clinical trial was conducted to compare IIV4 made by the currently licensed process with a vaccine made by the new (investigational) process (IIV4-I)...

BACKGROUND: Initial symptoms of dengue fever are non-specific, and thus definite diagnosis requires laboratory confirmation. Detection of IgM against dengue virus (DENV) has become widely used for dengue diagnosis. Understanding the persistence of anti-DENV IgM in subjects after acute infection is essential in order to interpret test results correctly. Although the longevity of anti-DENV IgM has been vehemently investigated in symptomatic children, anti-DENV IgM persistence in adults and in asymptomatically infected people have seldom been reported...

BACKGROUND: Respiratory syncytial virus (RSV) is the most common cause of lower respiratory tract infections (LRTI) during the first year of life. Antibiotic treatment is recommended in cases suspected of bacterial co-infection. The aim of this prospective study is to estimate the incidence of bacterial co-infections, and the amount of antibiotic overuse in children infected with RSV using expert panel diagnosis. METHODS: Children one month of age and over with LRTI or fever without source were prospectively recruited in hospitals in the Netherlands and Israel...

BACKGROUND: The typical manifestations of Penicillium marneffei (nowadays Talaromyces marneffei) infection in children without human immunodeficiency virus (HIV) remain unclear. The current work presents the case of a child without an underlying disease who was infected with P. marneffei comorbid with eosinophilia. CASE PRESENTATION: A 2-year-old male was infected with P. marneffei. A physical examination revealed a high-grade fever, ulcerated lesions in the oral mucosa, anemia, pruritic erythematous papules on the sac and thigh and watery diarrhea...

Here, we report the findings from the first 2 years of an arbovirus surveillance study conducted in Machala, Ecuador, a dengue-endemic region (2014-2015). Patients with suspected dengue virus (DENV) infections (index cases, N = 324) were referred from five Ministry of Health clinical sites. A subset of DENV-positive index cases ( N = 44) were selected, and individuals from the index household and four neighboring homes within 200 m were recruited ( N = 400). Individuals who entered the study, other than the index cases, are referred to as associates...

Background: Live respiratory syncytial virus (RSV) candidate vaccine LIDΔM2-2 is attenuated by deletion of the RSV RNA regulatory protein M2-2, resulting in upregulated viral gene transcription and antigen expression but reduced RNA replication. Methods: RSV-seronegative children ages 6-24 months received a single intranasal dose of 105 plaque forming units (PFU) of LIDΔM2-2 (n = 20) or placebo (n = 9) (NCT02237209, NCT02040831). RSV serum antibodies, vaccine infectivity, and reactogenicity were assessed...

During the last decades, the world has witnessed a dramatic increase in allergy prevalence. Epidemiological evidence shows that growing up on a farm is a protective factor, which is partly explained by the consumption of raw cow's milk. Indeed, recent studies show inverse associations between raw cow's milk consumption in early life and asthma, hay fever, and rhinitis. A similar association of raw cow's milk consumption with respiratory tract infections is recently found. In line with these findings, controlled studies in infants with milk components such as lactoferrin, milk fat globule membrane, and colostrum IgG have shown to reduce respiratory infections...

A tetravalent live-attenuated 3-dose vaccine composed of chimeras of yellow fever 17D and the four dengue viruses (CYD, also called Dengvaxia) completed phase 3 clinical testing in over 35,000 children leading to a recommendation that vaccine be administered to >/ = 9 year-olds residing in highly dengue- endemic countries. When clinical trial results were assessed 2 years after the first dose, vaccine efficacy among seropositives was high, but among seronegatives efficacy was marginal. Breakthrough dengue hospitalizations of vaccinated children occurred continuously over a period of 4-5 years post 3rd dose in an age distribution suggesting these children had been vaccinated when seronegative...

BACKGROUND: Rhinovirus (RV) is an established trigger of asthma attacks, whereas such a link is less consistent for influenza virus (IFV). OBJECTIVE: In the context of precision medicine, we hypothesized that IFV infection may cause a condition essentially different from RV, and we investigated this by evaluating clinical characteristics of RV/IFV-positive and -negative children with respiratory symptoms and/or fever. METHODS: 1207 children, 6-months to 13-years old, hospitalized for flu-like illness were recruited in this cross-sectional study...

BACKGROUND: Comparing post-vaccination fever rates in pediatric influenza vaccine clinical trials is difficult due to variability in how fever is reported. The impact of vaccine-related fever and antipyretic use on trivalent influenza vaccine (TIV) immunogenicity in children is also unclear. METHODS: In this pilot study, we obtained individual-level data provided by GlaxoSmithKline (GSK) from three pediatric clinical trials of GSK versus comparator TIV. We explored a primary study (NCT00764790), the largest trial involving young children (6-35 months, n=3317), and further explored key findings in the two other trials (3-17 years, NCT00980005; 6m-17y NCT00383123)...

Background: Pneumonia is a major cause of child mortality among children under 5 years, worldwide. Pneumonia infection may be caused by bacteria, viruses, or fungi in single or in both lungs. According to recent criteria developed by the World Health Organization(WHO) in September (2013), pneumonia can be classified into severe pneumonia, pneumonia and no pneumonia. Most of the deaths occur from severe pneumonia. Methods: Disease management of severe childhood pneumonia requires early identification,prompt referral and the availability of intensive quality care...

Haemophagocytic lymphohistiocytosis (HLH) is a possibly life-threatening syndrome of immune dysregulation and can be divided into primary (hereditary) and secondary forms (including malignancy-associated HLH (M-HLH)). We retrospectively analysed epidemiological, clinical, virological and laboratory data from patients with M-HLH treated at our department between 1995 and 2014. Out of 1.706 haemato-/oncologic patients treated at our department between 1995 and 2014, we identified 22 (1.29%) patients with secondary HLH (1...

Hepatitis A virus (HAV) causes an acute infection and is usually asymptomatic in children. When clinical manifestations appear, these include choluria, jaundice, and abdominal pain. Although infrequent, extra-hepatic manifestations related to HAV have been described, affecting the heart, bone marrow, blood vessels, and other tissues.A 10-year-old boy from a rural area presented with a 15-day history of malaise, fever, and jaundice; laboratory examinations were compatible with HAV infection. The patient turned encephalopathic and was remitted to our center, where laboratory examinations showed a medullary aplasia and fulminant hepatitis requiring a liver transplant that was performed 72 hours after admission...
