ABSTRACT
INTRODUCTION AND AIM:
Ulcerative colitis (UC) is characterized by chronic, uncontrolled inflammation of the intestinal mucosa. Gut microbiota dysbiosis was reported to be a factor in intestinal inflammation. The aim of the present study was to study changes in the gut microbiome in Egyptian patients with active UC. MATERIALS ANDMETHODS:
In this cross-sectional study, the gut bacterial microbiome of 21 UC patients and 20 control subjects was analyzed using the quantitative SYBR Green real-time PCR technique, targeting the 16S rRNA gene of selected bacterial phyla/genera and/or species.RESULTS:
UC patients showed marked dysbiosis evidenced by a significant decrease in the Firmicutes and F. prausnitzii anti-inflammatory bacteria. The Firmicutes/Bacteroidetes ratio was also lower in the UC cases (1.65), compared with the healthy controls (2.93). In addition, the UC cases showed a statistically significant decrease in Ruminococcus, compared with the control group. However, there were no statistically significant differences between UC patients and the controls, regarding A. muciniphila, Bifidobacterium, Lactobacillus, Bacteroides, and Prevotella. One UC case was positive for the pathogenic bacterium, Clostridioides difficile, with low relative abundance.CONCLUSION:
The current study showed differences in the gut microbiome of UC patients, compared with healthy controls. This may help in identifying the gut microbiome and specific bacterial changes that can be targeted for treatment of UC.
