GCA has just been given a slot on Radio 4. They talked to two patients and made the point that it can be very hard to diagnose. They also highlighted the fact that two-thirds of patients were likely to suffer from polymyalgia rheumatica. A rheumatologist that they talked to claimed that the difficulty of diagnosis meant that it could take two and a half months before treatment started. This seems very optimistic to me....most people seem to take much longer, whatever the specific type of vasculitis? The good thing was that he emphasised that correct diagnosis, and steroid treatment, was very important if patients were to retain their sight.
