The aim was to examine rifaximin plus lactulose efficacy in patients with cirrhosis at a risk of developing overt HE who were stratified by important baseline characteristics such as comorbid ascites ...
Pooled post hoc subgroup analysis of adults receiving rifaximin 550 mg twice daily plus lactulose or lactulose alone for 6 months in a phase 3 randomized, double-blind trial and a phase 4 open-label t...
Rifaximin plus lactulose was more efficacious than lactulose alone for reducing the risk of overt HE recurrence and HE-related hospitalization in adults grouped by select baseline disease characterist...
The non-absorbable disaccharide lactulose is mostly used in the treatment of various gastrointestinal disorders such as chronic constipation and hepatic encephalopathy. The mechanism of action of lact...
Hepatic encephalopathy (HE) is a major cause of mortality and morbidity in patients with cirrhosis. Lactulose non-adherence is one of the most frequently reported precipitants of hospital admission fo...
We aimed to identify which factors contribute most to lactulose non-adherence and propose strategies to promote greater adherence and utilization of lactulose....
Participants in this study consisted of patients with cirrhosis who were taking lactulose for prevention of HE. Subjects were administered the Morisky Adherence Scale 8 (MAS-8) and a customized 16-que...
We enrolled 129 patients in our study, of whom 45 were categorized as "adherent and 72 were categorized as "non-adherent." Barriers to adherence included large volumes of lactulose, high frequency of ...
We identified several factors that contribute to lactulose non-adherence among patients treated for HE. Many of these factors are potentially modifiable. Patient and care-giver education are critical ...
HE is a complication of cirrhosis characterized by neuropsychiatric and motor dysfunction, and results in decreased quality of life and increased mortality. Lactulose is a synthetic disaccharide used ...
Alterations in intestinal permeability can lead to increased uptake of luminal antigens, which has been linked to several intestinal diseases, such as inflammatory bowel diseases, celiac disease, and ...
This study aimed to investigate the clinical effect of probiotics combined with lactulose for minimal hepatic encephalopathy (MHE) treatment....
A total of 88 patients with MHE were randomly divided into the control ( n = 44) and combined groups ( n = 44). The control group was treated with lactulose, while the combined group was treated with ...
The post-treatment in the control and combined groups shows decreased serum ammonia levels, ALT and AST levels, FABP2 and AGEs levels and NCT-A score and increased DST score compared with pre-treatmen...
Probiotics can promote lactulose in MHE treatment....
Lactulose is an isomer of lactose, formed under thermal processing of milk. Alkaline conditions favor the isomerization of lactose. As reducing sugar, lactose and lactulose could participate in the Ma...
Patients with hepatic encephalopathy (HE) suffer from significant symptoms and impaired quality of life. Improved understanding on the potential benefits of first-line HE therapies may aid patient-pro...
We searched MEDLINE, EMBASE, and Cochrane Library databases for randomized trials or prospective cohort studies using lactulose and/or rifaximin for the management of HE and assessing changes in PRO u...
We identified 16 studies representing 1,376 patients that met inclusion criteria. Most studies assessed treatment of covert HE. In patients with covert HE, lactulose significantly improved overall pat...
Patients with HE treated with lactulose or rifaximin reported improvements in important PROs. These results may inform provider-patient communication and help manage patient expectations regarding the...
Cassia fistula is widely used in traditional Persian Medicine as a mild laxative. The rate of chronic constipation increases above the age of 60....
This study aimed to investigate the effect of Cassia fistula syrup (CFS) on geriatric constipation....
This clinical trial study was performed on 70 aged patients who were referred to the clinic of gastroenterology of Rouhani Hospital, Babol, North of Iran. Patients were randomly divided into two group...
The frequency of defecation per week varied from 1.82 ± 1.16 to 8.36 ± 3.44 in the CFS group after 2 weeks of intervention that was significantly more than the Lactulose that changed from 2.16 ± 1.46 ...
CFS can be more effective than Lactulose on geriatric constipation....
Cellobiose 2-epimerase (CE) is ideally suited to synthesize lactulose from lactose, but the poor thermostability and catalytic efficiency restrict enzymatic application. Herein, a non-characterized CE...
