Autologous Whole Blood Therapy in Autologous Serum Skin Test (ASST) Positive and Negative Chronic Idiopathic Urticaria Patients, a Clinical and Biochemical Randomized Controlled Trial.
To evaluate the efficacy of Autologous Whole Blood Therapy versus conventional treatment using fourfold dose of antihistamines in Autologus serum skin test (ASST) positive and negative Chronic Idiopathic Urticaria (CIU) patients and suggest its possible mechanism of action.
To evaluate the efficacy of Autologous Whole Blood Therapy (AWBT) versus conventional treatment using fourfold dose of antihistamines in ASST positive and negative Chronic Idiopathic Urticaria (CIU) patients and suggest its possible mechanism of action. Also, assessment of serum levels of D-dimer, IFN-γ, IL-6, anti-IgE IgG before and after treatment.
All patients will take desloratadine 10 mg at four-fold dose daily The AWBT test group patients will receive 8 doses of autologous whole blood therapy (AWBT) once weekly. The first dose will be 2.5ml and subsequent doses will be 5ml of venous blood, which will be drawn from any accessible vein under aseptic precautions. The blood will be re-injected immediately by deep intramuscular injection (IM) on alternate gluteal regions.
Patients will be advised to record the 7-day urticaria activity score (UAS 7) based on a simple questionnaire, on day 0, 4th week and 8th week of the treatment (End of Therapy (EOT)), and in the follow up period after 4 weeks following EOT (End of Study (EOS)). Dermatology life quality index (DLQI) will be assessed before treatment and at the end of therapy (8 weeks).
