Active clinical trials for "Hypersensitivity"

Background There is limited evidence indicating that specific immunotherapy in elderly patients is safe and effective. This study was performed to evaluate the safety and efficacy of specific subcutaneous immunotherapy (SCIT) against grass pollen allergens in patients over 60 years of age with seasonal allergic rhinitis (SAR) and a confirmed allergy to grass pollen. Objective This study assessed the safety and efficacy of SCIT for grass pollen allergens in elderly patients with SAR. Methods This study included 62 60- to 75-year-old patients with SAR and grass pollen allergy confirmed using a skin prick test, nasal provocation, and serum IgE measurement. The patients were individually randomized to the active or placebo groups using a double-blinded method. There were 33 subjects in the SCIT group (Purethal, Grass pollen, HAL Allergy B.V, Leiden, Netherlands) and 29 subjects in the placebo group monitored for three years. The patients were required to record each use of anti-allergy medication in a diary and use a visual graphic scale. The main outcome measure was the area under the curve (AUC) for the combined symptom and medication score (SMS).

Pilot study to assess the effect of oral immunotherapy on specific Immunoglobulin E (IgE) levels and antigen consumption in two distinct food allergies.

The long-term goal of the investigators study is to develop a better and safer treatment for, and to potentially cure patients with single or multiple food allergies. The investigators hypothesize that the application of this protocol will allow patients with severe and single or multiple food allergies to be safely and rapidly desensitized.

The aim of this trial is to assess the effect of hydrolyzed egg orally administered on oral tolerance induction to egg in children allergic to egg as compared to a placebo.

Aim: To evaluate the effectiveness of a desensitizing gel for topical and home use in the treatment of dentin hypersensitivity (DH) through a randomized clinical trial, double-blind, with three parallel treatment. Methods: 126 subjects were divided into three groups: placebo gel (PG), test gel (TG) (5% sodium fluoride, potassium oxalate 5%, strontium chloride 10%) and sodium fluoride gel (2% FG ). The measurement of DH was performed by a single examiner blinded by the visual analog scale (VAS) after tactile, thermal and osmotic stimuli in the Baseline, 7, 15 and 30 days.

Food allergy occurs when the immune system reacts against foods. The immune system is the part of the body that protects us from illness and germs, but it can also cause allergies. Peanut allergy occurs in 1 - 2% of people in the United States and other Western countries. There is proof that allergy to peanut is increasing. Allergic reactions to peanut can be severe and life threatening. The only way that you can prevent an allergic reaction is to avoid exposure to peanuts. However, peanut proteins are found in a variety of foods and people can be accidently exposed to peanut proteins. Treatment for accidental exposure include antihistamines (medications like Benadryl), and injectable epinephrine (adrenalin) which must be carried at all times. DBV Technologies has developed an epicutaneous delivery system, a patch that puts the peanut protein on the skin.

To examine whether Ritalin has analgesic properties in healthy subjects. To examine if Ritalin analgesic effect is a pain specific phenomenon or a part of a broader, non-specific effect on high mental functions.

Induction of oral tolerance in children allergic to cow's milk proteins is not risk-free. The analysis of factors that may influence the outcome is of utmost importance. The aim of the study is to analyse the efficacy and safety of the induction phase of oral tolerance induction according to specific IgE level, as well as adverse events during the maintenance phase. Patients allergic to cow's milk are to be included in an oral tolerance induction protocol. Patients will be grouped according to specific IgE levels in serum (ImmunoCAP) into group I (sIgE<3.5 kU/L), II (sIgE 3.5-17 kU/L) and III (>17-50kU/L). Allergic children with similar characteristics will included as a control group. Visits are established at 1, 6 and 12 months after the induction phase. Serum specific IgE levels to cow's milk and its proteins will be determined at inclusion, and at 6 and 12 months visits after the induction phase.

The purpose of this study is to determine the efficacy and the safety of the association of carboplatine and liposomal doxorubicin in patient with ovarian cancer in relapse, sensitive to platin.

A study to investigate the efficacy of ONO-8539 on acid-induced oesophageal hypersensitivity in healthy male adult volunteers.
