Outcome Measures

Primary Outcomes (1)

  • change in urticaria activity score (UAS7) from baseline to 8 weeks

    Change in 7-day urticaria activity score (UAS7) score from baseline to 8 weeks after treatment with either AWBT with fourfold antihistamines or fourfold of antihistamines alone in Chronic Idiopathic Urticaria (CIU) patients. urticaria activity score7 ranges from 0-42. A score of 0 means complete remission while score (28-42) means severe disease

    12 months

Secondary Outcomes (2)

  • correlation between ASST result and treatment response

    12 months

  • correlation between serum biomarkers and treatment response

    12 months

Study Arms (2)

AWBT plus antihistamines

EXPERIMENTAL

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.
