Brief Summary:
Many studies have been conducted to identify therapeutic strategies to modulate inflammation and oxidative stress, complications that contribute to the increased morbidity and cardiovascular mortality in patients with chronic kidney disease (CKD). Among several non-pharmacological strategies, the use of bioactive compounds has emerged as a potential approach to reduce these complications in CKD patients. In this context, turmeric/curcumin may have positive consequences in terms of cardiovascular and nephroprotection because of its antibacterial, antiviral, anti-inflammatory and anti-oxidative effects. The aim of this study is the role of curcumin as a nutritional strategy to reduce cardiovascular risk factors as inflammation and oxidative stress in CKD patients.

Detailed Description:

This is a longitudinal study of the type randomized crossover, double-blind, placebo-controlled, washout period. We selected 30 patients with CKD in hemodialysis at Clínica Renalcor / RJ (second sample calculation, considering p = 0.05 and test power of 80%). Eligible patients of both genders, previously evaluated and authorized by the medical staff of the clinic, were invited to participate in the research.

The research was carried out after signing the free and informed consent form, according to the standards of the local Research Ethics Committees and required by Resolution 466 of December 12, 2012 (Conselho Nacional de Saúde), based on the guidelines of the Declaration of Helsinki and of the World Medical Association on human research. This project was approved by the Ethics Committee of the Faculty of Medicine / UFF, number: 2.346.933. It is registered with ClinicalTrials.gov under the number NCT 03475017.

Inclusion and exclusion criteria:

Patients with stage 5 CKD (GFR <15 mL / min) on hemodialysis for more than 6 months, aged at least 18 years, and who had arteriovenous fistula (AVF) as vascular access were included in the study. Patients who were pregnant, smokers, antibiotics in the last 3 months, antioxidant supplements and habitual turmeric and / or turmeric intake, besides those with autoimmune and infectious diseases, cancer, hepatic diseases and AIDS were not included in the study.

Experimental Design

Patients who accepted to participate in the study and who were included in the inclusion and exclusion criteria were randomized into two groups:

  1. Turmeric Group: patients will receive juice containing 100 ml of orange juice, 12 grams of carrot and 2.5 grams of turmeric 95% curcumin 3 times a week for 12 weeks.
  2. Placebo group: patients will receive the same juice, however, without the addition of curcumin turmeric 95%, for the same period of time as the turmeric group.

The juices were prepared by the team responsible for the research project, and delivered to the patients after the end of the dialysis procedure. After the supplementation period, the 12-weeks washout was performed for subsequent crossover of the patients.
