ABSTRACT

INTRODUCTION: Phyllanthus niruri, a traditional herbal medicine, was found to be hepatoprotective as evidenced by several preclinical and clinical studies. However, to the best of our knowledge, there are no clinical trials available to date to evaluate its efficacy in alcoholic hepatitis. MATERIALS AND METHODS: The present study is a block randomized, double-blind, parallel-arm placebo-controlled trial that was designed to assess the efficacy of P. niruri on the liver and renal function parameters, total oxidant and antioxidant levels in alcoholic hepatitis patients in comparison to placebo over a 4-week period. Patients were screened by CAGE questionnaire, and those with a confirmed diagnosis of mild-moderate alcoholic hepatitis based on laboratory findings and Maddrey's discriminant function score were randomly allocated to treatment and placebo arms. Clinical assessments were done at baseline, 2 weeks, and 4 weeks. A total of 454 patients were screened and 100 eligible patients were recruited for the study, and 71 were analyzed using the modified intention-to-treat approach. RESULTS: Serum levels of liver and renal function parameters failed to demonstrate significant improvement with P. niruri. However, there was a statistically significant increase in the level of total antioxidants with P. niruri (P = 0.034) with an additional appetite stimulant activity (P = 0.03) in 4 weeks. CONCLUSION: A 4-week administration of P. niruri in mild-moderate alcoholic hepatitis patients showed an improvement in the total antioxidant levels with an appetite stimulant activity compared to a placebo.

ABSTRACT

Diabetes mellitus is characterized by increased central arterial stiffness and endothelial dysfunction leading to increased risk of cardiovascular complications. The aim of this study is to evaluate the effect of Curcuma longa on arterial stiffness and endothelial dysfunction in patients with type 2 diabetes mellitus. This randomized controlled trial was conducted in 136 patients of type 2 diabetes. Among them, 114 completed at least one follow-up visit and included for data analysis. Arterial stiffness parameters were measured at baseline and every month for 3 months and endothelial dysfunction markers at baseline and after 3 months of treatment with C. longa or placebo. These parameters were compared between the two groups. Both C. longa and placebo groups were comparable at baseline. After 3 months of treatment, C. longa produced significant reduction from baseline in carotid-femoral pulse wave velocity (p = .002), left brachial-ankle pulse wave velocity (p = .001), aortic augmentation pressure (p = .007), aortic augmentation index (p = .007), and aortic augmentation index at heart rate 75 (p = .018) as compared with the placebo group. Three months treatment with C. longa significantly decreases arterial stiffness as compared with placebo in type 2 diabetes mellitus patients.
