OBJECTIVE: The aim of the research was to investigate the spectrum of food sensitization, followed by the determination of the main clinical criteria and immunological markers of food allergy in children with gastroduodenal pathology and atopic dermatitis. PATIENTS AND METHODS: Materials and methods: We conducted a comprehensive clinical and immunological examination of 120 children aged from 6 to 15 years with gastroduodenal pathology (group 1; n = 64) and atopic dermatitis (group 2; n = 56), who had a history of adverse allergic reactions to food...

Several studies suggest that probiotics might be useful in the management of atopic dermatitis (AD). However, the efficacy and comparison between both the administration of viable and non-viable probiotics on alleviation of AD is not well studied. Therefore, the purpose of this study was to evaluate the effect of L. sakei proBio65 live and dead cells when administered (1 × 1010 cells/day) for 12 weeks to children and adolescents (aged 3 to 18) with atopic dermatitis. In this randomized double-blind, placebo-controlled study, ninety patients were recruited and randomly allocated to either the L...

Prostaglandin D2 (PGD2 ) plays an important role in atopic dermatitis (AD), and 11,15-dioxo-9α-hydroxy-2,3,4,5-tetranorprostan-1,20-dioicacid (PGDM) is a major metabolite of PGD2 . We investigated the relationship between urinary PGDM levels and severity of paediatric AD. In total, 31 patients with AD and 21 healthy controls (HCs) without AD were recruited, and urinary PGDM levels were measured. Of the 31 patients with AD, 14 were reassessed for urinary PGDM after topical steroid therapy. There was no difference in urinary PGDM levels between patients with AD and HCs...

Alterations in the composition and reduced diversity of the infant microbiome are associated with allergic disease in children. Further, an altered microbiota is linked to immune dysregulation, including skewing of different T helper (Th) subsets, which is also seen in atopic individuals. The aim of this study was, therefore, to investigate the associations between gut lactobacilli and Th-related plasma factors in allergy development during childhood. A total of 194 children with known allergy status at 1 year of age were followed to 10 years of age...

Mental disorders have for the majority of cases an unknown etiology, but several studies indicate that neurodevelopmental changes happen in utero or early after birth. We performed a nested case-control study of the relation between blood levels of neuro-developmental (S100B, BDNF, and VEGF-A) and inflammatory (MCP-1, TARC, IL-8, IL-18, CRP, and IgA) biomarkers in newborns, and later development of autism spectrum disorders (ASD, N = 751), attention deficit hyperactivity disorders (ADHD, N = 801), schizophrenia (N = 1969), affective (N = 641) or bipolar disorders (N = 641)...

BACKGROUND: We sometimes encounter difficulties in assessing the severity of pediatric atopic dermatitis (AD) using currently available biomarkers such as thymus and activation-regulated chemokine (TARC) due to the higher baseline values in non-AD children. Recent case control studies have indicated the usefulness of squamous cell carcinoma antigens (SCCAs) in pediatric and adult AD. Notably, SCCAs are induced by IL-4 and IL-13, vital Th2 cytokines that play important roles in AD etiology...

Individuals with autism spectrum disorder (ASD) suffer from developmental disabilities that impact communication, behavior, and social interaction. Immune dysregulation and inflammation have been linked to children with ASD, the latter manifesting in serum levels of macrophage-derived chemokine (MDC) and thymus, and activation-regulated chemokine (TARC). Mesenchymal stem cells derived from umbilical cord tissue (UC-MSCs) have immune-modulatory and anti-inflammatory properties, and have been safely used to treat a variety of conditions...

BACKGROUND: Treatment of atopic dermatitis (AD) is focused on topical anti-inflammatory therapy, epidermal barrier repair and trigger avoidance. Multidisciplinary treatment in both moderate maritime and alpine climates can successfully reduce disease activity in children with AD. However, it remains unclear whether abnormalities in B cell and T cell memory normalize and whether this differs between treatment strategies. OBJECTIVE: To determine whether successful treatment in maritime and alpine climates normalizes B- and T lymphocytes in children with moderate to severe AD...

BACKGROUND: An altered immune response against Staphylococcus aureus might contribute to inflammation and barrier damage in atopic dermatitis (AD). OBJECTIVES: To profile IgG antibodies against 55 S. aureus antigens in sera of children with mild-to-severe AD and to evaluate the association between IgG levels and disease severity. METHODS: In this cross-sectional study, we included children with AD from two interventional study cohorts, the Shared Medical Appointment (SMA) cohort (n = 131) and the older DAVOS cohort (n = 76)...

BACKGROUND: The aim of the study is to evaluate the relationship between serum periostin (POSTN), thymus and activation-regulated chemokine (TARC), and thymic stromal lymphopoietin (TSLP) levels and disease severity and atopy in children with atopic dermatitis. METHODS: Sixty children with atopic dermatitis and 31 healthy controls were included in the study. The disease severity was measured by SCORAD scores. Serum POSTN, TARC, and TSLP levels were measured in all participants...

BACKGROUND: Thymus and activation-regulated chemokine (TARC), a member of the CC chemokine family, plays a crucial role in Th2-specific inflammation. We aimed to determine the concentration of sputum TARC in children with asthma and eosinophilic bronchitis (EB) and its relation with eosinophilic inflammation, pulmonary function, and bronchial hyper-responsiveness. METHODS: In total, 90 children with asthma, 38 with EB, and 45 control subjects were enrolled. TARC levels were measured in sputum supernatants using an ELISA...

Atopic dermatitis (AD) is a multifactorial T-helper (Th)2-mediated skin disease frequently associated with elevated serum immunoglobulin (Ig)E and food allergy is also a Th2- and IgE-mediated adverse immunological reaction. Our previous study indicated the relation of egg allergy history and disease severity of AD. Thus, the purpose of the study was to investigate the levels of IgE specific to major food allergens (egg, milk, wheat) and Th2 chemokines (chemokine [C-C motif] ligand [CCL]17/thymus and activation regulated chemokine [TARC] and CCL22/macrophage-derived chemokine [MDC]) and the relationship between them...

BACKGROUND: Monokines induced by interferon-gamma/Chemokine (C-X-C motif) ligand 9 (MIG/CXCL9), thymus and activation-regulated chemokine/Chemokine (C-C motif) ligand 17 (TARC/CCL17) are chemotactic factors that specifically collect and activate leukocytes, which are considered as chemoattractants of T helper cells. In the present study, we have investigated the effects of T helper type-1 (Th1) cells and T helper type-2 (Th2) cells in Kawasaki disease (KD) by determining plasma levels of MIG/CXCL9 and TARC/CCL17 and exploring the relationship between MIG/CXCL9, TARC/CCL17 levels and coronary artery lesions (CAL)...

OBJECTIVE: To study the association of single nucleotide polymorphisms (SNPs, rs223895 and rs223899) in TARC/CCL17 gene with Kawasaki disease (KD) and its clinical characteristics in Han children from Central China. METHODS: A case-control study was performed on 218 children with KD and 248 normal control children. The genotypes of SNPs (rs223895 and rs223899) in TARC/CCL17 gene were determined by polymerase chain reaction-restriction fragment length polymorphism...

BACKGROUND: Many infants with atopic dermatitis (AD) are sensitized against food or airborne allergens. The severity of AD, using the SCORAD, seems to correlate with elevated serum levels of TARC/CCL17. Other chemokines, such as CCL20 or CCL25, have been described in the context of allergic inflammation. The aim of this study was to analyze whether chemokine serum levels differ within a cohort of infants suffering from varying severities of AD with or without allergic sensitization. METHODS: Chemokine serum levels (CCL8, CCL17, CCL20, CCL25) as well as food and airborne allergen-specific IgE were analyzed in infants with AD...

Chemokine and antibody response profiles were investigated in children and adults with severe or uncomplicated Plasmodium falciparum malaria; the aim was to reveal which profiles are associated with severe disease, as often seen in nonimmune children, or with mild and uncomplicated disease, as seen in semi-immune adults. Blood samples were obtained from children under 5 years of age as well as adults with falciparum malaria. Classification of malaria was performed according to parasite densities and hemoglobin concentrations...

BACKGROUND: Thymic stromal lymphoproetin (TSLP) is a cytokine secreted by the airway epithelium in response to respiratory viruses and it is known to promote allergic Th2 responses in asthma. This study investigated whether virally-induced secretion of TSLP is directional in nature (apical vs. basolateral) and/or if there are TSLP-mediated effects occurring at both sides of the bronchial epithelial barrier in the asthmatic state. METHODS: Primary human bronchial epithelial cells (HBEC) from control (n = 3) and asthmatic (n = 3) donors were differentiated into polarized respiratory tract epithelium under air-liquid interface (ALI) conditions and treated apically with dsRNA (viral surrogate) or TSLP...

Asthma and atopic dermatitis are common allergic diseases, and their prevalence has increased in urban children. Recently, it is becoming understood that forest environment has favorable health effects in patients with chronic diseases. To investigate favorable clinical and immunologic effects of forest, we examined changes in clinical symptoms, indirect airway inflammatory marker, and serum chemokines before and after a short-term forest trip. The forest trips were performed with 21 children with asthma and 27 children with atopic dermatitis...

Population cohort studies are important for understanding the current status of the target disease and its relation to comorbidity, gender, age, or environmental factors. To better understand atopic dermatitis (AD) and its related diseases, we initiated in 2001 a population cohort study of nursery school children from Ishigaki Island, Okinawa, Japan. The cohort study comprised a dermatologist-based physical examination, questionnaire administration, and blood sample analysis. The mean prevalence of AD was 6...
