Psoriatic Arthritis: An Assessment of Clinical; Biochemical and Radiological Features in a Single-Centre South African Cohort

BACKGROUND:Although psoriatic arthritis (PsA) is a well-documented clinical entity; epidemiological; clinical and radiological studies of South African (SA) patients are scarce.OBJECTIVES:To assess clinical; biochemical and radiological features in a single-centre SA cohort.METHODS: We conducted a prospective assessment of the clinical; biochemical and radiological features of 384 consecutive patients with PsA seen at the rheumatology clinic at Prince Mshiyeni Memorial Hospital; Durban; SA; between January 2007 and December 2013. Patients were assessed at enrolment and 6 months after enrolment. They were classified into five groups as described by Moll and Wright; being entered into the group that best described the clinical manifestations. Clinicopathological characteristics recorded at enrolment were age at the time of examination; racial background; personal and family medical history; age and symptoms at the onset of PsA; pattern of joint involvement; joint pain; and the relationship between joint pain and the onset of PsA.RESULTS:Of the patients; 59.1% had a polyarticular presentation indistinguishable from rheumatoid arthritis; 19.0% had distal interphalangeal involvement; 9.1% had spondyloarthropathy; 11.9% had oligoarthritis and 0.9% had arthritis mutilans. The epidemiological trends (male/female ratio 1.45:1; mean age at onset of arthritis 50.2 (standard deviation 11.8) years; female preponderance in the polyarticular group and male preponderance in the spondyloarthropathy and oligoarticular groups) were similar to trends published elsewhere. A notable characteristic of our cohort was the complete absence of black South Africans with PsA.CONCLUSIONS:The complete absence of black South Africans with PsA is interesting. We anticipate that our findings will prompt genetic studies to isolate both protective and susceptibility genes for further elucidating PsA

Health status of the elderly in the Marigot Health District, Dominica

The health status and the prevalence of hypertension, diabetes mellitus, glaucoma and visual disorders of 123 elderly people (56 men, 67 women) in the Marigot Health District, Dominica, were assessed by means of four questionnaires; collection of data from their medical records; physical examination, measurement of blood pressure, visual acuity and intra-ocular pressure (IOP); and testing for glucosuria. The overall health status was good, but 20were dependent on care. 74were independent in the activities in daily life, with only moderate limitations in activities. The health status decreased considerably in those over 75 years of age. There were slight perceived differences in health status between men and women. About 40of the study population were known to be hypertensive, and another 13had an elevated blood pressure on examination. Diabetes mellitus was present in 15. 20had a visual acuity of 0.1 or below, and 10had an elevated IOP. During the study, a considerable number of new cases of hypertension, diabetes mellitus and elevated IOP were diagnosed. 50of the study population who were on medication used this more than as prescribed. This study indicates a high prevalence of the secondary complications of hypertension, diabetes mellitus, cataract, glaucoma and osteo-arthritis that cause disability and dependency in the elderly population. Education, diagnosis at an early stage and appropriate treatment of these disorders may prevent or delay their development. We sugggest the development of a programme oriented approach of primary health care for the elderly to support this.
