Avalie o efeito dos simbióticos no MAFLD (MAFLD-RCT)
Um estudo duplo-cego randomizado controlado por placebo para avaliar o efeito dos simbióticos SLP07 na doença hepática gordurosa associada à disfunção metabólica (MAFLD-RCT)
Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide. Available data indicates that probiotics may regulate the gut microbiota, while Vitamin E and omega 3 are safe and effective at treating NAFLD patients. In this study, investigators aim to investigate if the enhanced synbiotic preparation of SLP07 is efficacious in liver function improvement in subjects with MAFLD.

Descrição detalhada
Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide.(1) The prevalence of NAFLD is estimated to be about 20%-30% in the Western world (2) and increasing in Asia. The prevalence of NAFLD across Asia varies from 5% to 40%.(3,4) The population prevalence of NAFLD in Hong Kong Chinese was 27.3%.(1) NAFLD may progress to non-alcoholic steatohepatitis (NASH), cirrhosis, liver failure and liver cancer, and is believed to be the leading etiology for cryptogenic cirrhosis.(5,6) NAFLD is also strongly associated with obesity and metabolic syndrome and is shown to be an independent cardiovascular risk factor.(7,8) Recently, a consensus by an international panel of experts recommended a change in name for NAFLD to metabolic dysfunction associated with fatty liver disease (MAFLD).(9) Patients who fulfil the MAFLD criteria have more severe metabolic and liver disease than those who fulfil the NAFLD criteria alone. At present, there is no standard pharmacologic therapy available for NAFLD or MAFLD currently.
Recently, it has been reported that NAFLD might be linked to small intestinal bacterial overgrowth (SIBO), which induces liver injury by gut-derived lipopolysaccharides (LPS) and TNF- α production. (10) Probiotics have several anti-inflammatory effects that can contribute to their clinical benefits in NAFLD.(11) Gut microbiota also plays a role in the development of insulin resistance, hepatic steatosis, necroinflammation and fibrosis. (12) The use of probiotics, prebiotics and synbiotics has been considered a potential and promising strategy to regulate the gut microbiota.(13,14) In the meantime, Vitamin E has been recommended for use in NAFLD treatmentand prevents liver injury. Moreover, many clinical trials and meta-analyses have evaluated the efficacy of omega 3 (C20-22 ω3 polyunsaturated fatty acids (PUFA)) in reducing existing NAFLD in adults and children, and the results indicate that omega 3 is safe and effective at lowering liver fat in NAFLD patients. (15,16)
In this study, investigators aim to investigate if the SLP07, which is an investigational product that contains a blend of naturally occurring food-grade Bifidobacterium and Lactobacillus strains, omega-3 and vitamin E, is efficacious in liver function improvement in subjects with MAFLD.

Descrição da medida |
Prazo |
|---|---|---|
|
Percentage of participants with a reduction of at least 1 grade of steatosis AND/OR >10% reduction in CAP scores at 3 months
Prazo: 3 months
|
The change of CAP score measured by fibroscan. CAP score is a measurement of fat accumulation in the liver to further determine the steatosis grade. The CAP score ranges from 100 to 400 decibels per meter (dB/m). The higher the score, the more the steatosis is. |
