RATIO OF MAIN PHYLOTYPES OF GUT MICROBIOTA IN PATIENTS WITH NON-ALCOHOLIC FATTY LIVER DISEASE DEPENDING ON THE BODY MASS INDEX.

OBJECTIVE

The aim: To analyze the status of Gut microbiota (GM) at the level of the main phylotypes in patients with NAFLD, depending on the body mass index (BMI) and gender in comparison with a group of practically healthy individuals.

PATIENTS AND

METHODS

Materials and methods: The study involved 120 patients with NAFLD, who were divided into two groups depending on BMI and the control group containing 20 practically healthy individuals.

RESULTS

Results

In patients with NAFLD with comorbid obesity, a statistically significant increase in the relative amount of Firmicutes (52.12 [42.38; 67.39]%) and Firmicutes/Bacteroidetes ratio (3.75 [1.7; 9.5]) against the background of a significant decrease in the amount of Bacteroidetes (13.41 [7.45; 26.07]%); in NAFLD patients with overweight, the relative amount of Firmicutes was 49.39 [37.47; 62.73]%, Firmicutes / Bacteroidetes ratio was 1.98 [1.15; 5.92], and the relative amount of Bacteroidetes was 23.69 [12.11; 36.16]%. In the control group, the distribution of the basic GM phylotypes was significantly different; the relative amount of Bacteroidetes was almost the same as of Firmicutes - 34.65 [24.58; 43.53]% and 29.97 [22.52; 41.75]% respectively, and the Firmicutes/Bacteroidetes ratio was 0.64 [0.52; 1.47].

CONCLUSION

Conclusions

The most statistically significant changes in the composition of IM occur due to the increase in the relative amount of Firmicutes and the ratio of Firmicutes/ Bacteroidetes against the background of a decrease in the relative amount of Bacteroidetes. These changes were directly proportional to the increase in BMI, but had no gender features.
