Introduction: Patients with systemic lupus erythematosus, particularly with lupus nephritis (LN), are at risk of premature cardiovascular (CV) disease. Objective: To determine the association between immunosuppressive medications, traditional CV risk factors and carotid intima media thickness (CIMT) among patients with LN. Methodology: This was a cross-sectional study in which consecutive LN patients attending the Nephrology/SLE Clinic were evaluated for traditional CV risk factors. Detailed information on their treatment was obtained from their medical records. CIMT, an excellent marker of subclinical atherosclerosis, was measured by B Mode carotid ultrasound. Results: A total of 82 patients with LN with a mean age of 33.9 +/- 9.8 years were recruited. More than half had hypertension (n = 55, 67.1%) and dyslipidemia (n = 43, 52.4%) as traditional CV risks. Longer history and higher cumulative dose of corticosteroids were associated with hypertension, but use of intravenous methylprednisolone was associated with lower systolic and diastolic blood pressure and lower serum total cholesterol and triglyceride levels (p < 0.05 each). Hydroxychloroquine use was associated with lower total serum cholesterol and serum low-density lipoprotein levels (p < 0.05). Although the use of cyclosporine A (CyA) was associated with hypertension (p < 0.05), those who received a lower cumulative dose of CyA had thicker CIMT (r(s) = -0.33, p = 0.01) and CyA use remained an independent predictor of CIMT during linear regression analysis. There were no associations between CIMT and cumulative dose and duration of steroids, hydroxychloroquine, azathioprine, mycophenolic acid and cyclophosphamide. Conclusion: Aggressive treatment of severe LN and the use of CyA as a steroid-sparing agent may have protective effects against premature atherosclerosis. Lupus (2011) 20, 1260-1266.

Aim: The objectives of this study were to investigate the frequency of thickened carotid intima media thickness (CIMT) and atherosclerosis among lupus nephritis (LN) patients and to study their associated risk factors. Method: In this cross-sectional study, carotid ultrasonography was performed on consecutive LN patients to determine CIMT and presence of carotid plaques. CIMT was considered to be abnormally thickened if it was more than the 75th percentile matched for age and sex from the 'Carotid Atherosclerosis Progression Study'. The association between thickened CIMT with traditional cardiovascular risk factors and lupus characteristics were examined. A total of 83 patients with the mean age of 33.6 +/- 10 years were recruited. Results: Fourteen patients (16.9%) had thickened CIMT and three (3.6%) had carotid plaques. On univariate analysis, traditional risk factors significantly associated with thickened CIMT (P < 0.05) were patient's current age, diabetes mellitus and waist circumference. Meanwhile, a lower serum C4 levels and higher serum C-reactive protein levels were the lupus-specific factors associated with thickened CIMT (P < 0.05, P < 0.05 and P < 0.01, respectively). In logistic regression analysis, the independent predictors of thickened CIMT were age of diagnosis, lower serum C4 levels and waist circumference (P < 0.05). Conclusion: More lupus specific factors were independently associated with thickened CIMT, suggesting that a multi-targeted approach of treatment addressing both the lupus and traditional cardiovascular risks are very important. Larger prospective studies of these special risk factors are indicated.

Myasthenia gravis (MG) is an immune mediated neuromuscular disease causing fatiguability, which can influence quality of life (QOL). MG disease status can be established with Myasthenia Gravis Quality of Life (MGQOL) 15 and Myasthenia Gravis Activities of Daily Living (MGADL) questionnaires to measure patients' perception of MG-related dysfunction. This study aims to validate the translated Malay versions of the MGQOL15 and MGADL for use in Malay-speaking MG patients. By using the cross cultural adaptation process, both questionnaires were translated into Malay language. Two sets of MGQOL15 Malay version and MGADL Malay version were distributed to MG patients during their routine follow-up to be filled up one week apart. A total of 38 patients were recruited during this study comprising predominantly females compared to males (71% vs 29%) and Malays compared to non-Malays (60% vs 40%). The mean age was 52.5 years; with most of the patients in the 60-69 years old category (37%). The Spearman's correlation coefficient was 0.987 for MGQOL-15 Malay version and 0.976 for MGADL Malay version, while the internal consistency for MGQOL15 Malay version was 0.952-0.957, and 0.677-0.694 for MGADL Malay version. The MGQOL15 Malay version and MGADL Malay version are reliable and valid instruments for the measurement of quality of life in MG patients in the local setting.
