Brief Summary: This a double blind randomised controlled trial (RCT) to determine the effect of Curcuma Xanthorrhiza supplementation on vitamin D3 administration to disease activity (SLEDAI), IL-6 and TGF-β1 serum in SLE patients with hypovitamin D. SLE patients with hypovitamin D had milder disease activity, lower IL-6 and higher TGF-β1 serum level when supplemented with Curcuma Xanthorrhiza and vitamin D3 compared with vitamin D3 and placebo.

Detailed Summary:

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 othe

Current Primary Outcome: SLE disease activity [ Time Frame: 3 months ]

SLE disease activity was assessed using SLEDAI in the last 10 days


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • IL-6 [ Time Frame: 3 months ]
    IL-6 serum level (pg/ml)
  • TGF-β1 [ Time Frame: 3 months ]
    TGF-β1 serum level (pg/ml)


Original Secondary Outcome: Same as current
