Cytomegalovirus (CMV) is a beta-herpesvirus that latently infects most adult humans worldwide and is a major cause of morbidity and mortality in immunocompromised hosts. Latent human CMV (HCMV) is believed to reside in precursors of myeloid-lineage, leukocytes and monocytes, which give raise to macrophages and dendritic cells. We report here that human monocyte derived DCs (mo-DC) suppress HCMV infection in coculture with infected fibroblasts target cells in an effector-to-target-ratio dependent manner. Intriguingly, optimal activation of mo-DC was achieved in coculture conditions, not by their direct infection with HCMV, implying that mo-DC may recognize unique molecular patterns on, or within, infected fibroblasts...

Despite robust vaccination schedules and high vaccination rates, many countries, including the U.S., have seen large pertussis outbreaks with a shift in recent years in the distribution of disease burden towards adolescents and young adults. Areas covered: This perspective covers problems related to the increased incidence of pertussis among adolescents. Because the Tdap vaccine only protects against pertussis for 1 to 2 years after vaccination, we propose a new strategy which aims to optimize the benefit of Tdap in adolescents...

Henoch-Schonlein purpura (HSP) is an immune-mediated vasculitis. HSP presents with purple spots on the skin (purpura), arthralgia, digestive problems, and kidney injury. HSP is most commonly seen in children, and rarely presents in adults. The pathogenesis involves the deposition of immune complexes in small to medium size blood vessels which leads to necrosis and inflammation. Most patients recover after symptomatic treatment, while more severe cases are treated with steroids. We report a 28-year-old female patient who presented with two episodes of hematemesis, worsening abdominal pain, and bloody diarrhea...

Globally the most commonly utilised immunisation against influenza is the trivalent inactivated influenza vaccine (TIV) derived from an A/H1N1, an A/H3N2 and aB type influenza virus. Vaccine effectiveness of TIV varies year to year, depending on how well antigenically matched the strains in the vaccine are compared to circulating strains [1,2]. Moreover, vaccine effectiveness can vary within certain subpopulations such as HIV-positive, young children and the elderly. Decreased vaccine effectiveness in the elderly is associated with impaired Ab production, as measured by standard hemagglutination inhibition (HAI) assays...

BACKGROUND: Atopic dermatitis (AD) is a chronic relapsing allergic inflammatory skin disease that currently affects millions of children and adults worldwide. Drugs used to treat these inflammatory diseases include anti-histamines, corticosteroids and calcineurin inhibitors but these drugs have their limitations such as adverse effects with their long-term usage. Thus, researcher's interest in several alternative and complementary therapies are continually growing and balneotherapy is one of these approaches...

BACKGROUND: Mexico introduced inactivated polio vaccine (IPV) into its routine immunization (RI) schedule in 2007 but continued to give trivalent oral polio vaccine (tOPV) twice a year during national health weeks (NHW) through 2015. OBJECTIVES: To evaluate individual variables associated with poliovirus (PV) shedding among children with IPV-induced immunity after vaccination with tOPV and their household contacts. MATERIALS AND METHODS: We recruited 72 children (both genders, ≤30 months, vaccinated with at least two doses of IPV) and 144 household contacts (both genders, 2 per household, children and adults) between 08/2010 and 09/2010 in Orizaba, Veracruz...

Atopic dermatitis (AD) is the most common inflammatory skin condition in adults and children. AD is a chronic disease that has a considerable negative impact on the quality of life of patients and their families. Most cases of AD may be effectively treated with topical therapies that are directed at decreasing cutaneous inflammation and alleviating pruritus. These therapies include emollients, antihistamines, topical corticosteroids, topical calcineurin inhibitors and antimicrobial and antiseptic measures; more refractory cases may require additional oral immunosuppression (eg, cyclosporine, azathioprine, methotrexate and mycophenolate)...

BACKGROUND: Invariant natural killer T (iNKT) cells play an important role in tumor immunity, enhancing both innate and acquired immunity. We have previously shown the enhancement of antibody-dependent cellular cytotoxicity against neuroblastoma by activated iNKT cells. As a first step towards clinical application, we studied the frequency and proliferative response of circulating iNKT cells in children with and without cancer. METHODS: Blood samples were collected from 10 patients with pediatric malignant solid tumors and 11 patients with non-neoplastic diseases (control)...

BACKGROUND: Systemic inflammatory response syndrome (SIRS) is a well-recognized phenomenon in adult trauma populations. The "initial hit" of the traumatic event is often coupled with a systemic immune response characterized by changes in vital signs and laboratory indicators. A "second hit" from surgery during this time frame often results in acute lung injury, along with deterioration of the patient's clinical condition. We hypothesized that children and adolescents would experience SIRS physiology, but would not experience adult respiratory distress syndrome (ARDS) or "second hit" related death to the extent seen in the adult populations...

Both sex (i.e., biological differences) and gender (i.e., social or cultural influences) impact vaccine acceptance, responses, and outcomes. Clinical data illustrate that among children, young adults, and aged individuals, males and females differ in vaccine-induced immune responses, adverse events, and protection. Although males are more likely to receive vaccines, following vaccination, females typically develop higher antibody responses and report more adverse effects of vaccination than do males. Human, nonhuman animal, and in vitro studies reveal numerous immunological, genetic, hormonal, and environmental factors that differ between males and females and contribute to sex- and gender-specific vaccine responses and outcomes...

C-reactive protein (CRP) and myxovirus resistance protein A (MxA) are associated with bacterial and viral infections, respectively. We conducted a prospective, multicenter, cross-sectional study of adults and children with febrile upper respiratory tract infections (URIs) to evaluate the diagnostic accuracy of a rapid CRP/MxA immunoassay to identify clinically significant bacterial infection with host response and acute pathogenic viral infection. The reference standard for classifying URI etiology was an algorithm that included throat bacterial culture, upper respiratory PCR for viral and atypical pathogens, procalcitonin, white blood cell count, and bandemia...

Occurring in at least 1 in 3,000 live births, chromosome 22q11.2 deletion syndrome (22q11DS) produces a complex phenotype that includes a constellation of medical complications such as congenital cardiac defects, immune deficiency, velopharyngeal dysfunction, and characteristic facial dysmorphic features. There is also an increased incidence of psychiatric diagnosis, especially intellectual disability and ADHD in childhood, lifelong anxiety, and a strikingly high rate of schizophrenia spectrum disorders, which occur in around 30% of adults with 22q11DS...

From the beginning of the twentieth century interest in tick-borne borreliosis continues to be an important diagnostic and therapeutic problem. In 1977, in Lyme and Old Lyme, Cunnecticut, in the United States, arthritis and skin lesions were described in 12 children, which were associated with tick bites. The name of the place was called a syndrome of Lyme disease. Dr Willy Burgdorfer observed microaerophilic Gram-negative bacteria (Spirochetes) with a diameter of 0.3-0.5 µm and a length of about 20-30 µm, which were isolated from the tick colon...

BACKGROUND: The epidemiology of the pandemic A(H1N1) virus has been changing as population immunity continues to co-evolve with the virus. The impact of genetic changes in the virus on human's susceptibility is an outstanding important question in vaccine design. In a community-based study, we aim to (1) determine the genetic characteristics of 2009-2015 pandemic H1N1 viruses, (2) assess antibody response following natural infections and (3) assess the correlation of A/California/07/09 antibody titers to protection in the 2013 and 2015 epidemics...

PURPOSE OF REVIEW: A new autoinflammatory disease, deficiency of adenosine deaminase 2 (DADA2), caused by mutations in the CECR1 gene, was first reported in 2014. This review aims to update progress in defining, treating, and understanding this multi-faceted disorder. RECENT FINDINGS: DADA2 was first described in patients with systemic inflammation, mild immune deficiency, and vasculopathy manifested as recurrent stroke or polyarteritis nodosa (PAN). More than 125 patients have now been reported, and the phenotype has expanded to include children and adults presenting primarily with pure red cell aplasia (PRCA), or with antibody deficiency...

Recent studies have suggested greater HIV cure potential among infected children than adults. A major obstacle to HIV eradication in adults is that the viral reservoir is largely comprised of HIV-specific cytotoxic T lymphocyte (CTL) escape variants. We here evaluate the potential for CTL in HIV-infected slow-progressor children to play an effective role in "shock-and-kill" cure strategies. Two distinct subgroups of children were identified on the basis of viral load. Unexpectedly, in both groups, as in adults, HIV-specific CTL drove the selection of escape variants across a range of epitopes within the first weeks of infection...

BACKGROUND: Airway epithelial cells (AEC) are quite difficult to access in newborns and infants. It is critically important to develop robust life-extended models to conduct translational studies in this age group. We propose the use of a recently described cell-culture technology (conditionally reprogrammed cells - CRC) to generate continuous primary cell cultures from nasal and bronchial AEC of young children. METHODS: We collected nasal and/or bronchial AEC from a total of 23 subjects of different ages including newborns/infants/toddlers (0-2 years; N=9), school age children (4-11 years; N=6), and a group of adolescent/adult donors (N=8)...
