Answer

USpA appears to carry a good-to-excellent prognosis, although some patients have chronic symptoms associated with functional disability. Erosive arthritis is very uncommon. Uveitis occasionally occurs and may be recurrent or chronic. Patients who develop sacroiliitis and spondylitis, by definition, have AS. [66, 54]
