Filter by:Wheat allergy is increasing in Thailand. Some studies show that cutaneous exposure of allergen may cause allergy and there are many wheat containing skin care products that are over-the-counter. So the purpose of our study is to determine level of specific immunoglobulin E antibodies to wheat and omega-5 gliadin in wheat allergy patients after stop using wheat containing skin care products.
This study will evaluate the effect of treatment of obstructive sleep apnea on insulin sensitivity in pregnant women. Women in their third trimester of pregnancy will be randomized to receive treatment or no treatment for one month.
Metabolic syndrome (MetS) is a group of important cardiovascular risk factors: abdominal obesity, dyslipidemia, hyperglycemia, and high blood pressure. Treatment requires lifestyle changes and pharmacological therapy with different medications for each component. Ellagic acid (EA) is a polyphenol that has shown health benefits in multiple experimental studies. Patients consume EA without prescription; considering there aren't studies that demonstrate its effectiveness on MetS, it is important to evaluate the possible effects of AE on this pathology. METHODOLOGY: Current study is a double-blind, placebo-controlled clinical trial. The aim of this study is to evaluate the effect of AE on the components of metabolic syndrome, insulin sensitivity, and insulin secretion.
Recently, an index based on the oral insulin sensitivity index with glucose (OGIS) has been proposed in combination with anthropometric variables, called PREDIcted M (PREDIM), however, there is no evidence of the correlation of this with respect to the various indices (McAuley, Belfiore, Cederholm, Avignon, Matsuda, Gutt, Stumvoll, HOMA-IR (Homeostatic Model Assessment for Insulin Resistance), ISI (Insulin Sensitivity Index), Raynaud, QUICKI (The quantitative insulin sensitivity check index), FIRI (Fasting Insulin Resistance Index), Bennett, TyG (triglycerides and glucose index)) in healthy patients.
Perioperative Acute Hypersensitivity (PAH) is a systemic reaction that occurs rapidly following injection of a drug during anesthesia.The HSA-PA reaction must occur within a maximum of one hour after the induction of anesthesia or a new product by the anesthetist. The main mechanism evoked is an immune response of immediate systemic hypersensitivity or anaphylaxis. Anaphylactic reactions are classically described as IgE-dependent and triggered by the injection of allergen which by bridging specific IgE present on the surface of mast cells, induces a massive release of histamine responsible for the observed symptoms. The diagnosis of this mechanism (IgE endotype) requires the determination of associated circulating mediators (histamine and mast cell tryptase) as well as skin tests performed during an allergologic evaluation. However, our previous work on patients with PAH (NASA study, ClinicalTrials.gov: NCT01637220) demonstrated that classical markers of IgE endotype are present in only 42% of patients. This finding has three consequences: - a diagnostic inaccuracy with deleterious consequences for the patient, - the existence of undocumented endotypes explaining the observed clinical manifestations, - a lack of formal identification of culprit drug, with uncertainty about the eviction recommendations leading to consequences for the safety of the patient. The investigators hypothesize that symptoms associated with PAH are caused by several distinct endotypes involving different cellular effectors and molecular mediators. These endotypes may be related to the immune system but independent of IgE, or independent of the immune system. To assess these endotypes, The investigators will be measuring the activation status of blood cells and a wide range of secreted mediators in blood drawn as soon as possible after PAH onset, and at steady state during a subsequent allergology visit. These data will be analyzed along with clinical data in multivariate analysis and clustering to define coherent profiles among patients. Definition of previously unexplored endotypes will allow to explain more PAH reactions and to design new diagnostic and therapeutic strategies. During the ENDOPHEN protocol, the measurement of a large number of biological parameters will be correlated with the clinical phenotype in patients who have presented a PAH. However, the procedures of general anesthesia themselves lead to a certain number of physiological modifications likely to modify the parameters measured in the ENDOPHEN protocol. This is why it was decided to carry out an ancillary study, the PHENZERO study, the objective of which is to measure the reference values of the parameters provided for in ENDOPHEN in an anesthetized population without any hypersensitivity phenotype ("zero" phenotype).
The aim of this 11 study analysis was to compare the effect of bioavailable stannous fluoride (SnF2) on dentine hypersensitivity versus a positive or negative control dentifrice.
Two-stage, prospective, observational, real-world study of HDM-SLIT-naïve children (aged 5-11) and adolescents (aged 12-17) consulting allergists or other specialist physicians in France for an HDM-induced allergy. Physician- and/or patient-reported data on clinical symptoms, sensitization, patient profiles, symptom burdens, patient-physician dialogue, HDM SLIT regimens, and effectiveness were recorded on inclusion, and then again 6 to 12 months after the prescription of an HDM SLIT solution. The study's primary objective was to describe treatment modalities in children (aged from 5 to 11) and adolescents (aged from 12 to 17) with suspected HDM-induced AR or allergic asthma consulting an allergist or another specialist physician in France.
This study investigates the effect of exercise on pain sensitivity in ongoing neck pain patients compared to a healthy control group.
Modern life is characterized by a 24-hour lifestyle in which food intake is no longer restricted to daytime. As a result, people nowadays tend to eat throughout the day. When food is being consumed the energy is both used and stored for later use. Eating for a prolonged period of time makes it unnecessary for the body to use its energy storage. It is hypothesized that the decreased use of energy stores has detrimental effects on our sugar balance, mainly on insulin sensitivity. Conversely, eating within a limited period during the day could improve insulin sensitivity in people with type 2 diabetes by an increased use of energy reserves, specifically liver sugar stores. Therefore, this study examines the effect of eating within a limited time frame during the day on insulin sensitivity and liver sugar stores of people with type 2 diabetes.
Objective 1. To investigate the status of food allergy among children aged 3 to 6 in Wenzhou and Taizhou urban areas. 2. To obtain the self-reported rate of parents or guardians of food allergy among children aged 3 to 6 in Wenzhou and Taizhou urban areas. 3. To obtain the prevalence of food allergy among children aged 3 to 6 in Wenzhou and Taizhou urban areas by conducting skin prick test (SPT), blood eosinophil (EOS) count, total immunoglobulin E (tIgE) measurement and serum specific IgE (sIgE) determination in children who self-reported food allergy, and conducting the open food challenge (OFC) if it is needed for further diagnosis. Methods The preschool children aged 3 to 6 from kindergartens in Wenzhou and Taizhou urban areas were selected by cluster sampling and random sampling to conduct a preliminary screening questionnaire. Then telephone interviewe the children who had diseases or problems caused by certain food or certain types of food. Make them finish further food allergy questionnaires, SPT, EOS, tIgE detection, sIgE detection. SPT has 17 kinds of food allergens including milk, egg white, egg yolk, shrimp, crab, wheat, mackerel, perch, cod, peanut, cashew nut, soybean, peach, pineapple, mango, orange and kiwifruit. sIgE has 10 kinds of food allergens including milk, egg white, shrimp, crab, soybean, peanut, wheat, nut mixed group and food mixed group. Children whose results of SPT and/or sIgE didn't meet the diagnostic criteria and children whose results of SPT and sIgE were negative but its history strongly supported food allergy need to conduct OFC. Descriptive analysis and risk factor analysis were carried out on the results, and SPSS 18.0 statistical software was used in statistics analyzation.
