BACKGROUND Inflammatory bowel diseases are managed by different methods, which may not be well tolerated because of their side effects. Recently, pro-prebiotics are considered as a supplementary treatment in gastrointestinal diseases. In this study, the effect of Lactocare® (ZistTakhmir Company) was investigated on the disease severity in mild to moderate ulcerative colitis. METHODS In this randomized, double-blind clinical trial (Iranian Registry of Clinical Trials number: IRCT201407271264N5), 60 patients with mild to moderate ulcerative colitis were included. An 8-week trial was carried out comparing Lactocare® as a supplement with standard therapy against placebo. Simple Clinical Colitis Activity Index (SCCAI) was measured at baseline and after 8 weeks. Statistical analysis was performed using paired ttest to assess the temporal changes (before and after the treatment) in the mean of SCCAI in each group. Chi-square test was used to compare the response rates. Odds ratios (OR) and the 95% confidence intervals (95%CI) were also calculated. p values of less than 0.05 were considered significant. RESULTS A significant decreased mean SCCAI was seen in the intervention group (4.56 ± 2.56) vs. placebo group (6.54 ± 2.47) (p < 0.05). Response to treatment was seen in 64.3% of the treatment group vs. 47% in the placebo group (p = 0.18). Response to treatment was observed in 90.9% of patients with ulcerative colitis for more than 5 years compared with 44.4% of the control group (p = 0.01). CONCLUSION Regarding the effectiveness of pre-probiotics in mitigating symptoms in patients with ulcerative colitis, it could be suggested to try pre-probiotics in the standard treatment particularly in those with more than five years ofthe disease.
Background: Cirrhosis could lead to a long corrected QT (QTc) interval in a subgroup of patients, but there are spare data on its diurnal variation. Objectives: The present study aimed to determine the diurnal variation of QTc interval and its relationship to heart rate and blood pressure variation during 24-hour Holter-monitoring in non-alcoholic cirrhosis in comparison with the healthy controls. Methods: The study population comprised 15 patients with non-alcoholic cirrhosis and 15 healthy subjects, undergoing 24-hour electrocardiogram (ECG), heart rate, and blood pressure monitoring. The mean QT interval, mean QTc, maximum and minimum QT, QT dispersion (QT disp), heart rate, and mean arterial blood pressure were measured for each person for 24 hours. Liver stiffness measurement (LSM) was performed by FibroScan® 502 machine (EchoSense, Paris, France, 5 MHz). The results were demonstrated as percentages and mean ± SD. P value ≤ 0.05 was considered significant. Results: Mean QTc was significantly higher in cirrhosis (438 ms) than healthy controls (401.7 ms) (P = 0.03). The mean heart rate was significantly different in cirrhotic patients (79.6 ± 2.9/bpm) compared to healthy controls (72.47 ± 2.0/bpm) (P = 0.05). Conclusions: In this study, QTc was prolonged and increased with the severity of cirrhosis, and its diurnal variation in cirrhosis was different from healthy subjects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
