Alternaria is the most important fungal species belonging to the class Deuteromycetes which causes allergic respiratory diseases. The fungus pattern often shows a pronounced seasonal periodicity and with fluctuations related to meteorological conditions. In this study, we aimed to investigate the effect of outdoor Alternaria spore concentrations on monthly lung function tests, symptoms, and medication scores in children sensitised only to Alternaria. Additionally, we planned to determine the Alternaria spores of the outdoor environment in Adana, with special respect to their relationships with meteorological conditions and their seasonal changes. Twenty-five patients with a clinical diagnosis of asthma and/or rhinitis sensitised only to Alternaria were enrolled in the prospective study. Meteorological data and outdoor samples of airborne fungi were obtained between November 2006 and October 2007. The outdoor Alternaria spore concentrations were significantly correlated with the monthly average temperature (r=0.626, p=0.03) and monthly average barometric pressure (r=-0.613, p=0.03). Similarly, the outdoor Alternaria spore concentrations were significantly correlated with mean monthly asthma medication score (r=0.599, p=0.04), value monthly PEF (r=-0.737, p=0.006), value monthly FEF25-75% (r=-0.914, p=0.0001) and, variation in PEF (r=0.901, p=0.0001). The atmospheric concentration of Alternaria spores are markedly affected by meteorological factors such as air temperatures and barometric pressures. In hypersensitive patients, Alternaria spores can induce decreases in respiratory functions and development of allergic symptoms between May and September, being especially more influential in August.

Background: The association between vitamin D receptor (VDR) polymorphisms and the risk of asthma remains unclear. This study aimed to investigate the effect of VDR gene polymorphisms and VDR mRNA expression levels on respiratory function, nitric oxide levels in expiratory air, and serum vitamin D levels in children with asthma. Materials and Methods: The study included 80 healthy children (control group) and 100 asthmatic children (asthma group) between the age of 5 and 18 years. The VDR genotypes ( Apa I, Taq I, and Fok I) and VDR mRNA levels were determined in all groups. Results: There was no statistically significant difference in vitamin D levels between the asthma group and the control group ( P > 0.05). A significant association was found between both genotype (CC) of the Taq I polymorphism [odds ratio (OR) = 0.2, 95% confidence interval (CI) (0.07–0.5), P = 0.003] and genotype (CA) of Apa I polymorphisms [OR = 0.2, 95% CI (0.07–0.8), P = 0.02], and asthma risk. In addition, when single-nucleotide polymorphism allelic frequencies between asthma and control groups were compared there is no significant association ( P > 0.05). When compared to control group, VDR mRNA expression in asthma group decreased in genotypes CC and CA of Apa I and in genotypes TT and TC of Taq I ( P < 0.05). Conclusion: The results provide supporting evidence for an association between Taq I and Apa I polymorphisms and asthma susceptibility.

Background: The purpose of the present research was to evaluate the quality of life of patients with atopic dermatitis (AD), and that of their mothers. We compared the anxiety and depression scores and caregiving burden of mothers of patients with AD with the same scores of mothers of healthy children. Materials and Methods: A total of 153 patients between the ages of 2 months and 16 years with AD in our clinic, and their mothers, were contained in the patient group. An additional 141 healthy cases between the ages of 2 months and 16 years, and their mothers, were included as the control group. The Children’s Dermatology Life Quality Index (CDLQI) was completed according to the children’s opinions, and the Infant’s Dermatitis Quality of Life Index (IDLQI), Family Dermatology Life Quality Index (FDLQI), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire, and Zarit Caregiver Burden (ZCB) scale were completed based on the mothers’ opinions. Results: We detected a positive relationship between the SCORAD index and the IDLQI, CDLQI, and FDLQI scores of children with AD. We found that anxiety, depression, and caregiving burden in mothers of AD cases increased when mothers of AD cases were compared with mothers of healthy children (p < 0.0001, p < 0.0001, and p < 0.002, respectively). Also, based on the mothers’ responses, we noted a positive correlation among the BDI, BAI, ZCB, and SCORAD index scores. Conclusions: Our study found that the quality of life of patients with AD, and that of their mothers, was negatively affected by the disease. We also found that anxiety, depression levels (not at the clinical diagnosis level, and the caregiving burden in mothers of AD cases increased when mothers of AD cases were compared with mothers of healthy children.

Background: Inclusion of baked-milk products to the diet appears to markedly accelerate tolerance to unheated milk compared to a strict avoidance diet.Objective: The present study aims to investigate the predictors of baked-milk tolerance in children with Immunoglobulin E (IgE)-mediated cow’s milk (CM) allergy.Methods: The study included 80 patients diagnosed with IgE-mediated CM allergy upon oral food challenge (OFC) testing at our clinic. Patients who developed and did not develop reactions during OFC with baked milk were compared considering clinical and laboratory parameters.Results: Eighty patients with CM allergy comprised 48 male and 32 female infants with an average age of 7.25 ± 2.45 (3–13) months. We found that 62.5% of them showed tolerance to baked milk in the OFC test performed with cakes containing 2.6-g milk protein. When the patients who tolerated and could not tolerate baked-milk products were compared for test results, we detected a statistically significant intergroup difference regarding diameter of wheal in skin prick test (SPT) performed with muffin slurry, levels of specific Immunoglobulin E (sIgE) in CM, sheep’s milk (SM), goat’s milk (GM), casein, and the amount of unheated milk consumed until a reaction developed in the OFC test performed with unheated milk (P < 0.05).Conclusion: We defined novel decision points based on CM, SM, GM, casein sIgE levels, wheal diameter in SPT with muffin slurry, and the amount of milk ingested during OFC performed with unheated milk that may be useful in predicting outcomes of baked-milk ingestion.
