Medical records of 138 patients with psoriatic arthritis and 138 with rheumatoid arthritis were reviewed for the occurrence of an environmental factor triggering arthritis. Twelve (9%) of the patients with psoriatic arthritis had had an acute disorder immediately preceding onset of arthritis (an operation in four cases, articular trauma in three, abortion in two, myocardial infarction, thrombophlebitis, and phosphoric ester intoxication in one case each). Peripheral arthritis occurred in all these patients. Among the rheumatoid patients, an acute event immediately preceding the onset of the disease was recorded in two cases (1%) only (chi 2 = 7.52; p = 0.006). No significant association was found in the arthritic patients between the incidence of acute events preceding arthritis onset and positivity of the HLA-B27 phenotype.

Rheumatol Int. 1992;12(1):7-11

Authors: Jurik AG

Material from a 10-year retrospective study of 268 patients with seronegative arthritis was analyzed with regard to the frequency of radiographic anterior chest wall (ACW) joint or bone lesions. Changes of the sternoclavicular joint were found in 17% of patients with ankylosing spondylitis (AS), in 6-9% of patients with reactive and psoriatic arthritis, and in 48% of patients with arthritis associated with palmoplantar pustular (PPP) lesions. The manubriosternal joint (MSJ) was involved in 51-57% of patients with AS and PPP lesions as well as in 18-24% of patients with reactive and psoriatic arthritis. The presence of ACW involvement was significantly related in AS, reactive and PPP associated arthritis to the duration of the disease; in AS to advanced sacroilitis, and involvement of the spine and root joints; in psoriatic and reactive arthritis to the presence of peripheral erosive polyarthritis; in reactive arthritis to sacroiliitis and spondylitis; and in psoriatic arthritis to root joint involvement.
