BACKGROUND: The pathogenic mechanisms underlying the increased vascular permeability in dengue hemorrhagic fever (DHF) are not well understood. Enhanced cellular immune activation, especially activation of serotype-cross reactive T cells, has been implicated in plasma leakage in DHF. Changes in several biological markers and mediators including cytokines, chemokines, angiogenic factors and their receptors have been shown to correlate with disease severity. A decline in plasma levels of a soluble form of vascular endothelial growth factor receptor 2 (VEGFR2), a receptor of vascular endothelial growth factor (VEGF), has been associated with plasma leakage in dengue patients...

BACKGROUND: Psoriasis is the disease of abnormal keratinocyte differentiation and apoptosis. Alterations in DNA methylation leading to keratinocyte hyperproliferation is one of the proposed pathogenic mechanisms of psoriasis. B-cell receptor associated protein (BCAP31) has been reported to be involved in the proliferation and apoptosis of keratinocytes. Up-regulation and changing in BCAP31 promoter methylation has been reported to be associated with some cancers. To date, there has been no study of psoriasis...

BACKGROUND: IL-35 is a novel cytokine suppressing the immune response through the expansion of regulatory T cells and suppression of Th17 cell development. Few studies have been done on the effect of this cytokine in a different disease. Asthma is a complex disease that many inflammatory cells and cytokines play a role in. OBJECTIVE: We decide to determine the difference between serum level of IL-35 in childhood asthma & healthy children. METHODS: We obtained serum samples from 44 asthmatic children between 2 and 15 years as a case group and from healthy children as a control group...

Wiskott-Aldrich syndrome (WAS) is a primary immunodeficiency disorder caused by mutations of the gene encoding WAS protein (WASp). A scoring system has been used to grade severity of the disease. However, the phenotype of the disease may progress over time, especially in children younger than 2 years of age. Here, we report a male child who presented with X-linked thrombocytopenia (XLT). Mutation analysis revealed a novel hemizygous 13-bp deletion (c.181_193delGCTGAGCACTGGA) on exon 2 of the WAS gene. This frameshift mutation resulted in a premature terminating codon at position 71 (p...

Infections due to non-tuberculous mycobacteria species are problematic for people who have immundeficiency. Mendelian Susceptibility to Mycobacterial Diseases (MSMD) defines a group of genetic defects affecting cellular interactions and IFN-γ pathway. Patients with MSMD may present with disseminated infection due to Bacillus Calmette-Guerin vaccine strain, Mycobacterium tuberculosis complex, environmental NTM or Salmonella species. Atypical mycobacterial infections and deficient granuloma/giant-cell formation are important clues for MSMD especially in patients with the history of parental consanguineous marriage...

Both asthma and obstructive sleep apnea (OSA) are common conditions involving the adults and children population, and have significant impact on the healthcare system. For the last few decades a lot of data emerged in terms of the prevalence between asthma and OSA. The prevalence ranges from 38% up to as high as 70%. Based on the current concepts of bidirectional relationship of OSA and asthma, it is sensible to assume that treating one disorder will result in the other's better control and vice versa. This review will look into the pathogenesis of concomitant OSA and asthma and whether the first line OSA therapy will result in better control of asthma in patients with concomitant OSA...

Our health and probably also our behaviors and mood depend not only on what we eat or what we do (lifestyle behaviors), but also on what we host. It is well established for decades that all vertebrates including humans are colonized by a wide array of bacteria, fungi, eukaryotic parasites and viruses, and that, at steady state (homeostasis), this community of microbes establishes a friendly mutual relationship with the host. The term microbiota was originally meant to represent an ecological community of commensals and potentially pathogenic microbes that live within our bodies, but it is now used interchangeably with the term microbiome which was initially meant to represent a collective genome of the microbiota...

BACKGROUND: MF59, which is an adjuvant belonging to C₃₀ member of the terpene family, is a T helper type-2 (Th2)-biased immune enhancer. Our previous studies showed that pyriproxyfen, a member of the terpene family with fewer carbon atoms (C₂₀) than MF59, enhanced active T helper type-1 (Th1)-biased immune responses. OBJECTIVE: This study was performed to investigate the enhancement of antigen-specific immune responses by myrcene, a member of the terpene family with fewer carbon atoms (C₁₀) than pyriproxyfen...

BACKGROUND: Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME), and Multiple Sclerosis (MS) may share some similarities in relation to reduced NK cell activity. It is likely that other cells such as regulatory T (Tregs), invariant Natural Killer T (iNKT) and gamma delta T (γδ T) cells may also be dysregulated in CFS/ME and MS. OBJECTIVE: To evaluate and compare specific immune regulatory cells of patients with CFS/ME, patients with MS and healthy controls...
