The current strategies for controlling tuberculosis (TB) are not sufficient. Improved prophylactic and diagnostic tools are imperative, being crucial for decreasing TB incidence and mortality and for preventing outbreaks. Furthermore, new and better drugs are badly needed, particularly considering the increase in cases with multidrug-resistant strains. The current TB vaccine-the Bacillus Calmette-Guérin vaccine-has a preventive impact on disseminated TB in children, but little effect on the most common form of TB, that is, lung TB in adults and young adults...

BACKGROUND: With approximately 3 billion people at risk of acquiring the infection, dengue fever is now considered the most important mosquito-borne viral disease in the world, with 390 million dengue infections occurring every year, of which 96 million manifest symptoms with any level of disease severity. Treatment of uncomplicated dengue cases is only supportive and severe dengue cases require hospital intensive care. A vaccine now licensed in several countries and developed by Sanofi Pasteur (CYD-TDV, named Dengvaxia), was able to protect, in the first 25 months of the two Phase III, 66% of a subset of 9-16 year old participants...

Chronic mucocutaneous candidiasis (CMC) is defined as recurrent or persistent infection of the skin, nails, and/or mucosae with commensal Candida species. The first genetic etiology of isolated CMC-autosomal recessive (AR) IL-17 receptor A (IL-17RA) deficiency-was reported in 2011, in a single patient. We report here 21 patients with complete AR IL-17RA deficiency, including this first patient. Each patient is homozygous for 1 of 12 different IL-17RA alleles, 8 of which create a premature stop codon upstream from the transmembrane domain and have been predicted and/or shown to prevent expression of the receptor on the surface of circulating leukocytes and dermal fibroblasts...

Human Respiratory syncytial virus (hRSV) and human metapneumovirus (hMPV) are the two major etiological viral agents of lower respiratory tract diseases, affecting mainly infants, young children and the elderly. Although the infection of both viruses trigger an antiviral immune response that mediate viral clearance and disease resolution in immunocompetent individuals, the promotion of long-term immunity appears to be deficient and reinfection are common throughout life. A possible explanation for this phenomenon is that hRSV and hMPV, can induce aberrant T cell responses, which leads to exacerbated lung inflammation and poor T and B cell memory immunity...

Atopic dermatitis (AD) is a common, chronic childhood skin disorder caused by complex genetic, immunological, and environmental interactions. It significantly impairs quality of life for both child and family. Treatment is complex and must be tailored to the individual taking into account personal, social, and emotional factors, as well as disease severity. This review covers the management of AD in children with topical treatments, focusing on: education and empowerment of patients and caregivers, avoidance of trigger factors, repair and maintenance of the skin barrier by correct use of emollients, control of inflammation with topical corticosteroids and calcineurin inhibitors, minimizing infection, and the use of bandages and body suits...

Around one third of the world's population may harbour latent tuberculosis infection (LTBI), an asymptomatic immunological state that confers a heightened risk of subsequently developing tuberculosis (TB). Effectively treating LTBI will be essential if the End TB Strategy is to be realized. This review evaluates the evidence in relation to the effectiveness of preventive antibiotic therapy to treat LTBI due to both drug-susceptible and drug-resistant bacteria. Current national and international preventive therapy guidelines are summarized, as well as ongoing randomized trials evaluating regimens to prevent drug-resistant TB...

Stanford T Shulman
From 1908 to 1929, Clemens von Pirquet was one of the world's most acclaimed pediatricians. Von Pirquet (1874-1929) trained at Vienna's Universitäts Kinderklinic under Theodor Escherich, the first Pediatric Infectious Diseases physician [ 1], and became the first Professor and Chair of Pediatrics at Johns Hopkins in 1909. He then succeeded his mentor Escherich as Professor and Chair of Pediatrics in Vienna, the most prestigious European pediatric position, when Escherich died unexpectedly in 1911. He held that position in Vienna until his shocking double suicide at age 54 with his wife in 1929...

Serious psychiatric disorders such as schizophrenia, bipolar disorder, and major depression are important causes of mortality and morbidity worldwide. While these are primarily diseases involving altered brain functioning, numerous studies have documented increased rates of gastrointestinal inflammation and dysfunction in many individuals with these disorders. Toxoplasma gondii is an apicomplexan protozoan intracellular parasite with a widespread distribution in both developed and developing countries. Toxoplasma organisms enter the ecosystem through the shedding of oocysts by Toxoplasma-infected felines...

In cross-sectional studies, chronic helminth infections have been associated with immunological hyporesponsiveness that can affect responses to unrelated antigens. To study the immunological effects of deworming, we conducted a cluster-randomized, double-blind, placebo-controlled trial in Indonesia and assigned 954 households to receive albendazole or placebo once every 3 mo for 2 y. Helminth-specific and nonspecific whole-blood cytokine responses were assessed in 1,059 subjects of all ages, whereas phenotyping of regulatory molecules was undertaken in 121 school-aged children...

Respiratory tract infections are among the most frequent infections in humans causing millions of deaths especially in children and the elderly. Antibiotics and vaccines are the main available tools of control, but resistant strains are continuously arising and available vaccines only account for few of many pathogens involved. Non-specific immunotherapies are an emerging alternative to induce protective immunity at the airways. Mucosally administered polyvalent bacterial lysates (PBLs) have been widely used for decades for prevention of respiratory diseases, but the bases of their proposed therapeutic effectiveness are still controversial...

Establishment of Helicobacter pylori infection as an etiologic agent of peptic ulcer disease and other gastric pathologies marked a revolution in gastroenterology which spurred an enormous interest in gastric physiology and immunology research. The association was soon also demonstrated in children as well. Application of antimicrobial therapies have proven remarkably efficacious in eradicating H. pylori and curing pediatric patients of duodenal ulcers as well as gastritis, negating a lifetime of ineffective therapy and life-threatening disease...

Disease-free infection in HIV-infected adults is associated with human leukocyte antigen-mediated suppression of viremia, whereas in the sooty mangabey and other healthy natural hosts of simian immunodeficiency virus (SIV), viral replication continues unabated. To better understand factors preventing HIV disease, we investigated pediatric infection, where AIDS typically develops more rapidly than in adults. Among 170 nonprogressing antiretroviral therapy-naïve children aged >5 years maintaining normal-for-age CD4 T cell counts, immune activation levels were low despite high viremia (median, 26,000 copies/ml)...
