Objective: Lactulose is effective in the treatment and prevention of overt hepatic encephalopathy (OHE), but there are limited data on its use on microbiota in relations to minimal hepatic encephalopathy (MHE) recovery. The present study aimed to assess the efficacy of lactulose in recovery of MHE in aspects of cognitive function, quality of life, and impact on intestinal microbiota. Methods: This multicenter, open‐label randomized controlled trial was conducted in 11 teaching hospitals in China. Participants were randomly allocated on a 2:1 basis to receive lactulose (Gp‐L) or no therapy as control (Gp‐NL) for 60 days. The primary endpoint was the MHE reversal rate. Gut microbiota were compared between MHE patients and healthy volunteers, as well as lactulose‐responders and non‐responders. Results: A total of 98 cirrhotic patients were included in the study, with 31 patients in the Gp‐NL group and 67 patients in the Gp‐L group. At day 60, the MHE reversal rate in Gp‐L (64.18%) was significantly higher than that in Gp‐NL (22.58%) (P =.0002) with a relative risk of 0.46 (95% confidence interval 0.32‐0.67). Number needed to treat was 2.4. Further, there was significantly more improvement in physical functioning in Gp‐L (4.62 ± 6.16) than in Gp‐NL (1.50 ± 5.34) (P =.0212). Proteobacteria was significantly higher in MHE patients compared with healthy volunteers (12.27% vs 4.65%, P < .05). Significant differences were found between lactulose responders and non‐responders in Actinobacteria, Bacteroidetes, Firmicutes, and Proteobacteria. Conclusions: Treatment with lactulose significantly improves MHE recovery rate, and gut microbiota change in MHE patients can modulate the effectiveness of this therapy.

Background and Aims Upper gastrointestinal endoscopy remains the gold standard for diagnosis of esophageal varices. Trans-abdominal ultrasound, as a noninvasive routine examination for the follow-up of cirrhosis patient, is safe, cheap, easy to perform, and plays an important role. In this study, we attempt to design a practical classification analysis model to predict esophageal varices via ultrasound. Methods Compared with endoscopy, the ultrasound qualitative signs (lower esophageal Doppler signals, left gastric vein hepatofugal flow, and paraumbilical vein recanalization) and quantitative parameters (spleen diameter, spleen vein diameter, portal vein diameter, and portal vein velocity) have been evaluated in 286 cirrhosis patients. Results The classification analysis model is designed as that: the patients are defined with esophageal varices high risk, who with any ultrasound qualitative signs or who with spleen diameter greater than 162 mm without qualitative parameters. The sensitivity for detecting esophageal varices is 97.5% and the specificity is 82.6%, while the positive predictive value is 96.7%, negative predictive value is 83.4%, and the omission diagnostic rate is 2.5%. Conclusions This classification analysis model design includes ultrasound qualitative signs and spleen diameter, which can be detected easily via routine ultrasound without other auxiliary. The classification analysis model is useful in detecting esophageal varices, which may be a supplement for predicting of esophageal varices, and reducing the frequency of endoscopy in the follow-up of cirrhosis patients.

Aim: We conducted this study to evaluate the role of multidetector computed tomography (MDCT) in diagnosing and differential diagnosis hepatic veno-occlusive disease (HVOD), and as well as assessing the clinical therapeutic effects. Methods: From 2007 to 2010, 10 inpatients with weight increasing, liver pains, ascites, jaundice and history of taking gynura rhizome before hospitalization were scanned with a 64-MDCT. The data were reconstructed every 0.625 mm and reviewed using multiplanar reconstruction (MPR) and liver CT angiography (CTA) on a GE AW4.2 workstation. Patients were re-scanned with MDCT after medication so that the clinical therapeutic effect could be evaluated before the patients discharging from hospital. Results: In 10 HVOD patients, the diagnoses of MDCT were coincident with clinical results. All patients had ascites and pleural fluid, hepatomegaly except the caudate lobe in MDCT. Failure to view hepatic veins in hepatic 3 phase scans, but portal veins and inferior vena cava were unobstructed. In portal-phase, hepatic enhancements were non-uniform. Three patients were incorrectly diagnosed before hospital admission. All patients improved significantly after hepato-protection and supporting therapy. No ascites, hydrothorax, hepatomegaly and obstruction of hepatic veins were observed by MDCT before patients were discharged from hospital. Conclusion: Multidetector computed tomography combined with MPR and liver CTA images are helpful in the diagnosis and differential diagnosis of HVOD and in the evaluation of clinical therapeutic effects.
