Objectives: Hypovitaminosis D is common in the general population. Many studies that have been conducted to show the association between vitamin D deficiency and systemic lupus erythematosus (SLE) reveal that deficiencies in vitamin D are common in this group of patients.

Methods: Retrospective cohort study of patients with SLE who were followed up at King Abdulaziz University Hospital, Jeddah, from January 2007 to November 2010. Demographic and clinical data were recorded and the 25(OH)D levels of the patients were measured. Chi square tests, Student’s t-test, ANOVA and Pearson tests were used for data analysis. ANOVA test was followed by Bonferroni correction. A p-value 120 mmol/L or estimated glomerular filtration rate 801 IU/mL. Complement components 3 and 4 (C3 and C4) were measured by nephelometry, and hypocomplementemia was defined as a level below the lower normal value (C3
