Cholecalciferol 1200 IU supplementation for 3 months in hypovitamin D SLE patients, decrease SLEDAI, however, it has not reached the mild activity and remission yet. Curcumin contained in Curcuma Xanthorrhiza; is an immunomodulator that has similar biological effect with vitamin D. Combination of curcumin and vitamin D are expected to work synergistically.
The subjects who fulfilled inclusion criteria, willing to participate in the research and signed the informed consent were 40 patients. Research subjects were randomized using simple randomization. The subjects were divided into 2 groups: the group receiving 3×400 IU cholecalciferol and 3×1 tablet placebo (group I, n=20), and the group receiving 3×400 IU and curcumin (Curcuma Xanthorrhiza) 3x20 mg for 3 months (group II, n=20).
Fifteen cc of venous blood samples were taken for complete blood tests, liver function (SGOT/SGPT), renal function (ureum/creatinine), vitamin D (25(OH)D), calcium, anti-dsDNA, C3, C4, IL-6 and serum TGF-β1. Examination of vitamin D levels using Enzyme Immuno Assay method (Diasorin Inc, Stillwater, MN USA), anti-dsDNA levels using ELISA (Bioluminescenassay), C3, C4, IL-6 and serum TGF-β1 using ELISA (Biolegend). Proteinuria was examined using a urine spot sample while with enzymatic-turbidimetric methods. SLE disease activity was assessed using SLEDAI score. Laboratory and SLEDAI examination were performed at the beginning of the study and the end of the study; except for the serum calcium levels examined each month to determine the side effects of the drug.
Patients continue to receive the usual immunosuppressive drugs (corticosteroids, chloroquine, cyclophosphamide, mycophenolate mofetil, azathioprine, and cyclosporine), as well as calcium, antihypertensive drugs and other routine medications. Regular drugs, cholecalciferol, Curcuma Xanthorrhiza and placebo, are administered by a physician in the Rheumatology Outpatient Clinic who is not a member of the research team in different examination rooms.
The results are presented in mean ± standard deviation, median (IQR 25-75%) and n (%). The homogeneity test of variance using Levene. The Saphiro-Wilk test is used to determine the normality of the data, assuming the normality of the data is fulfilled if p> 0.05. Different tests after treatment in both study groups used a non-paired/Mann-Whitney test. The influence between variables was tested using Spearman/Pearson correlation test. Data analysis uses Statistical Package for the Social Sciences Software version 22 (SPSS Inc, Chicago IL). Differences and correlations are said to be significant when the value of p <0.05.
