berberine and non-alcoholic fatty liver disease (nafld)

Conditions: Non-Alcoholic Fatty Liver Disease

Summary: non-alcoholic fatty liver disease (nafld), one of the most common liver dysfunctions, affects about one-fourth of the global adult population and has a significant mortality rate between 6.3% and 33%.nafld can lead to other serious illnesses. the disease is associated with a group of metabolic comorbid conditions, including type 2 diabetes mellitus (t2dm), obesity, hypertension, and hyper-cholesterolemia, which are potential risk factors for progressive liver disease.this study sought to evaluate the therapeutic effect of berberine on the liver function and metabolic profiles of patients with nafld. in this context,a six week, open-label randomized controlled trial was conducted in a single medical center at takestan hospital, iran. a total of 281 patients with nafld were enrolled and randomly assigned to treatment arm with (n=24) or without (n=24) berberine. all patients had received pre-randomization lifestyle training including recommendations on low-fat diet. blood examinations were performed to evaluate glucose, lipid profile, and liver enzymes both at the beginning of the study and upon the completion of the trial (day 45). to assess tolerability of the study intervention and any possible adverse events, patients in both groups were required to attend weekly follow-up visits.

a seven-week (45-day), open-label, randomized controlled trial was conducted in a medical center affiliated with the ministry of welfare and social security in iran to study the impact of berberine on liver function and metabolic profiles of patients with nafld. hospital employees who met the enrollment criteria were identified through electronic health records (ehrs) available in a human resource database of employee routine annual examinations. using a computer-generated random-allocation sequence, eligible employees were equally assigned (1:1) to berberine 6.25 g per day (arm a) or no intervention (arm b). berberine was administered orally (100 g dried berberine in 5 liter water boiled at 167°f until 4liter).). to control the potential impact of confounders on outcome measures, and to balance the daily dietary and physical activity among the study groups, all participants were trained by skilled experts on lifestyle and behavior improvement.
