DOI: 10.1191/096120398678920569 Mucocutaneous disease in Arabs with systemic lupus erythematosus: Clinical expression and relevance to autoantibodiesDepartment of Internal Medicine in Mafraq Hospital, PO Box 2951, Abu Dhabi, United Arab Emirates
Department of Internal Medicine in Mafraq Hospital, Abu Dhabi, United Arab Emirates Both criterial and non-criterial mucocutaneous manifestations of 42 Arabs with systemic lupus erythematosus are reviewed. Photosensitivity occurred in 40.5%, malar rash in 35.75% and oral ulcers in 26% of patients. Subcutaneous nodules and subcutaneous lupus erythematosus (SCLE) were not seen, and there were few cases of discoid rash (DLE), Raynaud's phenomenon, livedo reticularis and SLE-related sicca and anticardiolipin syndromes. In the clinical relevance of autoantibodies in these patients, there was a significant association between anti-Sm antibodies and oral ulcers (P = 0.033) and, interestingly, between anti-cardiolipin (aCL) antibodies and lack of photosensitivity (P = 0.014). The report also reviews previously presented data on mucocutaneous LE in Arab and non-Arab patients and emphasises the presence of intra-and inter-racial variations of SLE expression including the clinical relevance to autoantibodies.
