Protocol summary

Study aim
The effect of curcumin-piperine supplementation on inflammatory factors and clinical signs in patients with rheumatoid arthritis
Design
This study is a clinical trial with a control and randomized parallel double-blind group, in which 50 patients with rheumatoid arthritis will be divided into two groups receiving curcumin-piperine supplement (n = 25) and placebo (n = 25).
Settings and conduct
In this study, people with rheumatoid arthritis will be admitted to Al-Zahra Hospital. Random allocation will be done using a random number table. Entry of individuals and assignment of each person to one of the two groups will be done by the relevant specialist. Curcumin-piperine supplement and placebo will be packaged in similar boxes and the researcher and patients will not be informed of the contents of the packages until the end of the study.

Randomization (investigator's opinion)
Randomized
Randomization description
Participants will be divided into intervention and control groups using block classified randomization. The following authoritative site will be used to allocate the intervention in the above-mentioned manner. https://www.sealedenvelope.com/simple-randomiser/v1/lists In this way, people are randomly divided into two groups of intervention and control using quadruple blocks based on age and sex. It is noteworthy that participants and outcome assessors will not be aware of patient grouping and will be blind to it.
Blinding (investigator's opinion)
Double blinded
Blinding description
In order to conduct this research in a double-blind manner, before starting the study, the total capsules are coded in A and B by a person other than the researcher, so that both groups do not know the type of capsules received by both groups. To keep track of people in the study groups using the capsules, they will be contacted weekly by phone or text message and will be reminded of the capsule use. To check patients' compliance, curcumin and placebo capsules are given to them on a monthly basis and they are asked to deliver the previous capsule pack so that we can give them the new pack. Capsule use is also reminded and evaluated by weekly phone calls and text messages.
