Abstract
UNLABELLED Recurrent proctitis and the symptoms associated therewith pose significant clinical problem in proctological patients. The objective of this study was to assess the impact of the probiotic Lactobacillus rhamnosus PL1 strain on the clinical presentation and composition of intestinal microbiota in patients with symptoms of proctitis in the course of hemorrhoidal disease and diverticulosis. Material consisted of 24 patients in whom no complete clinical improvement could be obtained after the treatment of the underlying disease. Subject to the assessment was the presence and the intensity of clinical symptoms as well as qualitative and quantitative changes in the composition of bacterial flora detected in the stool before, during and after a 9-week supplementation with the probiotic Lactobacillus rhamnosus PL1 strain. RESULTS In the entire study group, the intensity of pain after 12 weeks was significantly lower (p=0,.011) compared to baseline; the intensity of flatulence and abdominal discomfort was reduced significantly as early as after 3 weeks, with the difference reaching a highly significant level after 12 weeks (pP<0,.0001). No significant difference was observed in the frequency of the reported episodes of diarrhea, constipation, as well as itching and burning in the anal region. As early as after 3 weeks of supplementation with the probiotic L. rhamnosus PL1 strain, significant qualitative and quantitative changes were observed in the composition of intestinal microbiota; the changes differed depending on the underlying disease. An increase in the total counts of the bacteria of Lactobacillus genus, particularly L. rhamnosus PL1 strain was observed regardless of the underlying disease. CONCLUSION Tthe probiotic Lactobacillus rhamnosus PL1 strain appears to be useful in restoring appropriate ratios of bacterial populations in patients presenting with symptoms of proctitis in the course of the treatment of certain diseases of the lower gastrointestinal tract.

Abstract
BACKGROUND Changes within the gut microbiota contribute to the progression of chronic liver diseases. According to the results of several studies performed in animal models, gut dysbiosis plays an important role in hepatocarcinogenesis. The aim of this study was to explore the characteristics of gut microbiota associated with the presence of hepatocellular cancer (HCC) in patients with cirrhosis of the liver undergoing liver transplantation. METHODS A total of 15 patients with HCC and 15 non-HCC patients matched according to etiology of cirrhosis and Model for End-Stage Liver Disease (MELD) scores who underwent liver transplantations between 2012 and 2014 were included. Analysis of their gut microbial profile was based on prospectively collected stool samples from the pretransplant period. RESULTS Patients with and without HCC were similar with respect to age (P = .506), sex (P = .700), hepatitis C virus (P > .999) and hepatitis B virus (P = .715) infection status, alcoholic liver disease (P > .999), and MELD score (P = .337). Notably, the presence of HCC was associated with significantly increased fecal counts of Escherichia coli (P = .025). Prediction of HCC presence based on E coli counts was associated with the area under the receiver-operating curve of 0.742 (95% confidence interval, 0.564-0.920), with the optimal cutoff on the level of 17.728 (natural logarithm of colony-forming units per 1 g of feces). Sensitivity and specificity rates for the established cutoff were 66.7% and 73.3%, respectively. CONCLUSIONS The profile of gut microbiota associated with the presence of HCC in cirrhotic patients is characterized by increased fecal counts of E coli. Therefore, intestinal overgrowth of E coli may contribute to the process of hepatocarcinogenesis.

Abstract
BACKGROUND The gut microbial ecosystem plays an important role in the pathogenesis of liver diseases. However, the association of microbial community structure with the severity of liver dysfunction is not completely understood. METHODS Fecal microflora was assessed in 40 patients with liver cirrhosis listed for primary liver transplantation (LT). Independent associations between fecal microbial counts and serum bilirubin, serum creatinine, international normalized ratio (INR), and the Model for End-stage Liver Disease (MELD) score were established in multiple linear regression models. RESULTS Bifidobacterium (standardized regression coefficient [sβ] = -0.549; P < 0.001), Enterococcus (sβ = 0.369; P = 0.004), and yeast (sβ = 0.315; P = 0.018) numbers were independently associated with serum bilirubin, while Escherichia coli counts (sβ = 0.318; P = 0.046) correlated with INR, and Bifidobacterium counts (sβ = 0.410; P = 0.009) with serum creatinine. Only Bifidobacterium (sβ = -0.468; P = 0.003) and Enterococcus (sβ = 0.331; P = 0.029) counts were independent predictors of the MELD score. Bifidobacterium/Enterococcus ratio, proposed as a measure of pre-LT gut dysbiosis, was significantly related to the MELD score following the adjustment for the absolute Bifidobacterium (sβ = -0.333; P = 0.029) and Enterococcus (sβ = -0.966; P = 0.003) numbers. This pre-transplant dysbiosis ratio (PTDR) was significantly correlated with Enterococcus (R = -0.897; P < 0.001) but not with Bifidobacterium (R = 0.098; P = 0.546) counts. Among the other components of gut microflora, only hydrogen peroxide (H2 O2 )-producing Lactobacillus strains significantly influenced Enterococcus counts (sβ = 0.349; P = 0.028) and PTDR (sβ = -0.318; P = 0.046). CONCLUSION While the abundance of both Bifidobacterium and Enterococcus is related to liver dysfunction, the size of the Enterococcus population seems to be the most important determinant of pre-LT gut dysbiosis in cirrhotic patients. The H2 O2 -producing Lactobacillus strains potentially ameliorate this dysbiotic state.
