Preference for Clarinex Tablets vs. Allegra Tablets in Patients With Seasonal Allergies (Study P03177)...

Seasonal Allergic Rhinitis

This was a crossover study designed to see if patients with seasonal allergy symptoms preferred Clarinex® or Allegra®. Patients were randomized to take 7 days of Clarinex or Allegra treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Allegra, the patient prefers more.

Rhinitis, Cognition and Driving Performance

Seasonal Allergic RhinitisDriving Ability1 more

This study investigates the effects of Allergic Rhinitis (AR) on driving ability and memory functions. Our group has previously shown that patients suffering from AR symptoms perform less well on tasks requiring sustained attention compared to non symptomatic controls. Car driving is a typical behavior that is susceptible for changes in sustained attention and might therefore become worse under conditions when patients suffer from AR symptoms. We will compare the driving performance of untreated, symptomatic AR patients with the performance of symptomatic patients that have been treated with either a systemic AR medication (a pill) or a topical medication (nasal spray)

Comparison of the Influence of Different Skin Conditions on the Allergic Skin Reactivity to Epicutanous...

Birch Pollen Allergy

It is an open-label physiological investigation of the allergic skin reactivity to epicutaneous allergen exposition in 20 allergic patients in two different skin conditions. The focus of the study is on the skin preparation/condition and not on the specific allergen or allergy, but for reasons of homogeneity a single allergic disease, birch pollen allergy was chosen as the basis for the testing. In order to evaluate the effects of the two different skin preparation techniques an intraindividual comparison of the skin reactivity in terms of the immediate phase I reaction to serial dilutions of birch pollen extracts was chosen. The serial dilution approach allows a dose dependent effect evaluation and comparison of the sensitivity. The differences will be explained mainly by the two different skin preparations allowing a quantitative comparison of these techniques.

Seasonal Allergic RhinitisPerennial Allergic Rhinitis

This was a crossover study designed to see if patients with allergy symptoms preferred Clarinex® or Zyrtec®. Patients were randomized to take 7 days of Clarinex or Zyrtec treatment, followed by a 5 to 28-day washout period (days when no drug is given), followed by 7 days of the opposite treatment. At the end of each 7-day treatment, patients were asked questions to determine which drug, Clarinex or Zyrtec, the patient prefers more.

Effect of Veramyst and Olopatadine 0.2% Opthalmic Solution on Allergy Symptoms

Seasonal Allergic Rhinitis

People who have hayfever or allergic rhinitis often complain about eye symptoms associated with their nasal symptoms. How people with hayfever develop eye symptoms is not clear. The purpose of this study is to better understand the generation of eye symptoms in patients with allergic rhinitis. We have previously shown that placing the substance that subjects are allergic to in their nose causes both nose and eye symptoms. This can be explain by a parasympathetic neurogenic reflex from the nose to the eye. Such a reflex would readily explain the tearing and watery eye symptoms, but does not explain the itch. In this study, we are going to address one possible explanation for the itch; does an axonal neurogenic reflex stimulate mast cells in the eye to release histamine, which then causes the itch? We will do this by placing an antihistamine drop in the eye and challenge the nose with allergen. We will also attempt to demonstrate that mast activation isn't effected by blocking the initiating of the reflex with a nasal steroid, as done in our previous study, and showing that the addition of an antihistamine does not add to the reduction of symptoms.

Effect of a 10,000 EU Dose of Endotoxin in Allergic and Mildly Asthmatic Adults

RhinitisAllergic5 more

The purposes of this pilot safety study are to identify a dose of inhaled Clinical Center Reference Endotoxin (CCRE) that is well tolerated by allergic subjects that induces measurable increases in neutrophil content of induced sputum that can be employed to screen large populations for susceptibility to the inflammatory effect of inhaled endotoxin.

Effect of Intranasal Corticosteroids on Systemic Allergen Specific IgE

Seasonal Allergic Rhinitis

Evaluation of the effect of fluticasone propionate vs placebo applied as nasal spray on the increase of allergen-specific serum IgE levels following nasal exposure to recombinant allergens. Nasal sprays will be applied for four weeks starting two weeks before nasal provocation and serum IgE levels will be followed during eight weeks after nasal provocation.
