Detailed Description:

Chronic idiopathic urticaria is thought to affect approximately 0.1% of the population. It can be very disabling and difficult to treat. Antihistamines are the only drugs licensed for treatment of urticaria, however there is a group of severely affected patients with chronic idiopathic urticaria who fail to respond. Previous trials have shown ciclosporin to be beneficial, and small studies support the use of intravenous immunoglobulins and plasmapheresis. However, not only are these options expensive, but since chronic idiopathic urticaria may persist for years, their prolonged use may be limited by adverse effects. We have previously published a report of 2 patients who responded to methotrexate, and wish to properly evaluate the efficacy of methotrexate in the treatment of CIU.

In the first part of the study patients will be given either placebo or methotrexate for 8 weeks and in the second part of the study, non-responders will be offered open labelled methotrexate for 8 weeks.
