Protocol summary

Study aim
Evaluation of the effect of curcuminoids supplementation on markers of insulin metabolism, biomarkers of inflammation and genes expression of TNF-α and IL-1 in patients with diabetic nephropathy
Design
In this research, 60 patients with diabetic nephropathy who are eligible will be selected. Participants are randomly divided into two groups of intervention and control by computer software. The design of the study is parallel blind randomized clinical trial
Settings and conduct
Sixty patients with diabetic hemodialysis who are eligible and are referred to dialysis center of Akhavan clinic affiliated to Kashan University of Medical Sciences, Kashan, Iran will be selected. Fasting blood samples will be taken at baseline and after 12 week intervention

Intervention groups
Patients will be assigned to receive either curcuminoids (intervention group: n=30) or placebo (control group: n=30).
Main outcome variables
Markers of insulin metabolism (primary outcomes) and inflammatory factors, oxidative stress biomarkers and gene expression related to inflammation (secondary outcomes) will be quantified at study baseline and end-of-trial.
