The use of an anti-inflammatory supplement in patients with chronic kidney disease

Area of Science:

• Nephrology
• Immunology
• Nutraceuticals

Background:

• Chronic kidney disease (CKD) is marked by declining kidney function, heightened inflammation, and reduced antioxidant defenses.
• CKD patients often exhibit elevated systemic inflammation and impaired antioxidant status, potentially exacerbated by comorbidities.
• Understanding these metabolic disturbances is crucial for developing supportive therapies.

Purpose of the Study:

• To evaluate the impact of a herbal supplement on systemic inflammation and antioxidant capacity in non-dialysis CKD patients.
• To investigate the effects of Curcuma longa and Boswellia serrata on key inflammatory and oxidative stress biomarkers.
• To assess the safety and tolerability of the herbal supplement in this patient population.

Main Methods:

• A randomized, placebo-controlled study involving 16 non-dialysis CKD patients.
• Participants received either a herbal supplement (Curcuma longa and Boswellia serrata) or a placebo for 8 weeks.
• Plasma levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), glutathione peroxidase (GPx), and serum C-reactive protein (CRP) were measured.

Main Results:

• Baseline measurements confirmed elevated inflammation and reduced antioxidant levels in CKD patients.
• A significant time effect was observed for interleukin-6 (IL-6) levels (p=0.03).
• The herbal supplement was found to be safe and well-tolerated, with a trend towards improved inflammatory cytokine levels.

Conclusions:

• Mild and moderate CKD is associated with chronic inflammation and diminished antioxidant activity.
• The herbal supplement containing Curcuma longa and Boswellia serrata appears safe and tolerable for CKD patients.
• Further research is warranted to confirm the efficacy of these herbs in managing inflammation and oxidative stress in CKD.
