effect of sinbiotic with multispecies probiotics on liver parameters liver enzymes, ultrasound, elastography and adipokines in same cases) in patients with metabolic associated steatotic liver disease.

Conditions: MASLD/MASH (Metabolic Dysfunction-Associated Steatotic Liver Disease / Metabolic Dysfunction-Associated Steatohepatitis); Diabetes Mellitus; Hypertension; Hyperlipidaemia

Summary: scientific hypothesis: the use of a synbiotic preparation with a multi-strain probiotic in patients with masld can lead to a decrease in non-invasive elastographic parameters of hepatic steatosis and fibrosis and an improvement in liver function. the main objective of this study is to examine whether the test product affects the improvement of liver function measured by elastographic parameters or at least the prevention of further disease progression. the goal of this clinical trial is to learn if sinbiotics works to improve liver function in adult patients with masld the main questions it aims to answer are: does sinbiotic lowers elastographic parameters od steatosis and fibrosis? does it change liver function by lowering liver enzymes, blood lipids and sugar? can sinbiotics lower cv risks and improve quality of life? researchers will compare sinbiotic to a placebo (a look-alike substance that contains no drug) to see if sinbiotic works in masld patients. participants will: take sinbiotic or a placebo every day (td) for 9 months visit the clinic once every 3 months for checkups, and at the begining and after 9 months for blood tests and us with elastography keep a diary of their symptoms, diet, activity

this is a randomized, multicenter, double-blind 1:1 clinical study lasting 3 years, which is planned to begin on january 2, 2025. the study will include 114 patients of both sexes over the age of 18, who suffer from masld and are monitored in the gastroenterology and/or endocrinology outpatient department of the šibenik-knin county general hospital and cooperating institutions (sestara milosrdnica clinical hospital, split clinical hospital, dubrava clinical hospital, merkur clinical hospital, požega general and county hospital, zadar general hospital, rijeka clinical hospital). patients will take the prepared preparation (synbiotic or placebo) for 36 weeks at a dose of 2x1 capsule per day. during the study, they will keep a diary of consumption and possible side effects, and every three months they will pick up coded packages of the preparation at the gastroenterology clinic of their institution. cooperation will be checked by telephone calls and by reviewing the diary at monthly intervals, and more often if necessary. patients will regularly take their usual chronic therapy, especially antihypertensives, antidiabetics, and hypolipidemics, they will be recommended appropriate physical activity during the week and a diet in accordance with the recommendations of professional societies, and the use of herbal preparations and other dietary supplements is prohibited. serum samples will be taken from the patients at the beginning of the study and at the end of the intervention for routine biochemical tests, and for the elisa test of human lrg1 and adiponectin in some centers (after 9 months of using the test preparation or placebo). in addition to the above, an ultrasound of the liver, fibrocan, and in some centers elastography on an aloka arietta ultrasound system will be performed in the same interval. all patients will have their bmi, waist circumference, and arterial pressure values measured using a standard method, and they will complete a questionnaire on quality of life and the score2 cv risk table.
