摘要

Objectives To find the common clinical features, pattern of visceral involvement, treatment received and outcome in patients diagnosed as having systemic lupus erythematosus (SLE) on American Rheumatological Association (ARA) criteria. Setting Clinic for patients referred or admitted to the University Medical Unit, National Hospital of Sri Lanka, Colombo, with diagnosed or suspected SLE. Design and methods A prospective descriptive study. Clinical features of patients collected at time of registration in the clinic were maintained in a database. Patients were followed up prospectively and changes recorded. Data were analysed after 3 years of follow up. Results Of the 111 patients registered during this period, 96 (86%) were clinically diagnosed as having SLE. Of these, 77 patients (80%) satisfied ARA criteria for diagnosis of SLE. 72 were females (93%). The mean age of patients who satisfied the ARA criteria was 32 years (range 11 to 58), and the mean duration of disease 7 years (range 1 to 15). The commonest presentation was with mucocutaneous features (98%) and alopecia in 87%. Systemic features were found in 92% of patients. 67 (87%) of patients had visceral involvement with 60 (78%) having it at time of diagnosis. 53 (69%) had renal, 42 (54%) haematological, 33 (42%) neurological, 12 (16%) cardiac and 8 patients pulmonary involvement. Five patients died during the 3-year follow up and 2 developed chronic renal failure. Three patients underwent successful pregnancy after diagnosis of SLE.Conclusions Our study confirmed the wide variability of clinical features seen in SLE. Alopecia and visceral involvement were common in Sri Lankan patients.?DOI: http://dx.doi.org/10.4038/cmj.v45i4.6589 Ceylon Medical Journal 2000; 45(4): 162-165
