Filter by:Depression and other unhealthy behaviors, such as not taking medication as prescribed and not attending doctor visits have been suggested to increase the worsening of allergic diseases (e.g. asthma, urticaria). We intend to determine whether a one-session behavioral intervention is effective in helping with depression and controlling disease symptoms. We will measure this using pre- and post-intervention surveys.
To compare CSU disease activity at the end of the follow up phase between patients that had been treated daily continuously vs. on-demand in the treatment phase
Histamine is a biologically active component that can be found in many foods and beverages. Intake of excessive histamine from foods or beverages, can trigger symptoms including urticaria. A low histamine diet has been recommended as one of the possible treatments for patients with chronic urticaria. There are very few studies to confirm the effectiveness of such diets and, to the investigators' knowledge, none from Asia where high histamine containing meals are often eaten (personal observations). The objective of the present study is to investigate the therapeutic effect of low histamine diet in relieving symptoms in patients with chronic urticaria with or without angioedema, and / or pruritus (U/A/P). The investigators hypothesize that following a low histamine diet for 4 weeks, the symptoms of patients with chronic U/A/P should improve.
Randomised, double-blind, placebo-controlled study evaluating the effects of miltefosine on skin lesions in patients with treatment resistant chronic urticaria. Treatment resistance is defined by insufficient treatment response after a minimum of 1 week therapy with the maximum labelled dose of a non-sedating antihistamine. Eligible subjects will be enrolled at baseline 8 (+/- 1) days after screening. 75 Patients will be randomised in a 2:1 ratio to one of the following treatment groups as add-on to the ongoing therapy with a non-sedating antihistamine for treatment period of 4 weeks: 25 placebo and 50 active drug Efficacy and safety evaluations are done at baseline day 7, 14, 21 safety, only) and 28 (or end of treatment) and at day 56 (28 days after end of treatment).
Levocetirizine (Xyzal®), the active levorotatory enantiomer of cetirizine (Zyrtec®), is a FDA-approved drug used in the treatment of symptoms associated with seasonal and perennial allergic rhinitis and chronic idiopathic urticaria. The parent compound, cetirizine was shown to be effective against experimental dermatographism, however no study has been conducted so far on the effect of levocetirizine on the inhibition of dermatographism. It is known that cetirizine is a mast-cell stabilizer and decreases histamine levels and the number of tryptase positive mast cells. Cetirizine inhibits the production of interleukin 8 (IL8) and leukotriene B4 (LTB4) by immune cells - two potent chemoattractants - and induces the release from monocytes of prostaglandin E2 (PGE2), a suppressor of antigen presentation and MHC class II expression. However, the effects of the most active enantiomer levocetirizine on these inflammatory mediators have not been evaluated so far. Therefore, we aim to conduct a study in humans with dermatographism and chronic idiopathic urticaria to evaluate the effect of levocetirizine on the above-mentioned mediators. The study will involve the use of skin microdialysis, a minimally invasive technique to measure inflammatory mediators in the extracellular space in dermis.
This was a randomized, double-blind, parallel-group, multicenter study that used both an active control (cetirizine) and a placebo control to evaluate desloratadine 5 mg once daily during a 28-day treatment period. The active treatments and placebo were allocated in a 2:2:1 ratio.
This study is being done to find out if a drug called Rituxan (Rituximab) is safe and effective in treating people with chronic urticaria (hives) with persistent symptoms in spite of taking antihistamines.
· To evaluate the efficacy of rupatadine 10 and 20 mg for the treatment of CIU symptoms over four-week treatment period in comparison with placebo.
The objective of this study is to evaluate the efficacy and safety of rupatadine for the treatment of CIU symptoms.To assess the clinical efficacy of a dose ranging of rupatadine fumarate (5mg, 10mg, and 20 mg) compared with placebo for relief of CIU symptoms.
The purpose of this study is to determine whether methotrexate produces significant improvement in chronic idiopathic urticaria, compared with placebo
