Abstract
Patients (33%) with psoriatic spondyloarthropathy referred to a rheumatic disease unit had radiological sacroiliitis. The majority of these patients had definite or probable spondylitis according to the New York criteria. Abnormal sacroiliac uptake of 99mTcPP on bone scan correlated well with the radiological finding of sacroiliitis. In addition, 8 patients with normal radiographs had an abnormal uptake of radionuclide over the sacroiliac joints, indicating sacroiliitis. Patients with sacroiliitis tended to have more severe psoriasis. Sacroiliitis occurred in association with all of the patterns of peripheral joint involvement which may occur in psoriatic arthritis. Although the HLA antigen B27 was present in only 21% of the total group and in 33% of those with sacroiliitis, 8 out of 10 with this antigen had sacroiliitis.
