Vasculitis is an inflammation of the small blood vessels in the body leading to a restriction of blood supply to organs and tissues. When the kidneys or lungs are affected, “plasma exchange” can be used as an effective treatment option. It quickly removes an antibody called ANCA (as well as other harmful substances) so that the disease can be controlled and kidneys and/or lungs can recover. The treatment method of plasma exchange combined with drugs (steriods and cyclophosphamide), is effective at controlling the disease but has toxic side effects, particularly infections. It is important to use the correct dose of these drugs in order to balance their benefit with their side effects but unfortunately it is unknown what the correct dose should be.
The PEXIVAS Trial is open to patients with ANCA Vasculitis where the kidneys and/or lungs are affected. They are randomised to either receive plasma exchange or no plasma exchange and a standard dose of steriods or a reduced dose of steriods. The study runs for seven years and the results will reveal the ideal dosage for controlling Vasculitis and in doing so, greatly improve the quality of life of those with Vasculitis.
