BACKGROUND Recently, polyethylene glycol (PEG 3350) has been suggested as a good alternative laxative to lactulose as a treatment option in paediatric constipation. However, no large randomised controlled trials exist evaluating the efficacy of either laxative. AIMS To compare PEG 3350 (Transipeg: polyethylene glycol with electrolytes) with lactulose in paediatric constipation and evaluate cl...

About 5% of normal subjects fail to produce increased hydrogen breath concentration after ingestion of the non-digestible carbohydrate lactulose (low hydrogen producers). The existence of low hydrogen producers limits the diagnostic use of hydrogen (H2) breath tests. We studied the effects of lactulose and of magnesium sulphate (MgSO4) pretreatment on stool-pH and on hydrogen exhalation after o...

BACKGROUND Hepatic encephalopathy (HE) is associated with poor prognosis and treatment of HE is primarily directed at the reduction of the blood ammonia levels. The study evaluated the efficacy and safety of albumin plus lactulose versus lactulose alone for treatment of overt HE. METHODS In prospective randomized controlled trial, 120 patients with overt HE were randomized in two groups: grou...

Lactulose, which cannot be digested and absorbed by body, is clinically widely used to treat constipation and hepatic encephalopathy. Fermented by gastrointestinal tract bacteria, lactulose can produce considerable amount of hydrogen, which is protective for DSS-induced colitis as a unique antioxidant. We propose that lactulose is an indirect antioxidant that mobilizes endogenous hydrogen produ...

BACKGROUND Gut microbiota may be altered in patients with cirrhosis, and may further change after administration of lactulose. We studied the composition of gut microbiota in patients with cirrhosis and assessed the effect on it of lactulose administration. METHODS Stool specimens were collected from 35 patients with cirrhosis (male 26; median [range] age: 42 [29-65] years) and 18 healthy con...

Lactulose is a non-digestible disaccharide formed from fructose and galactose. The objective of this study was to assess the effect of lactulose on gastrointestinal function after cesarean section. One hundred patients who underwent cesarean section at the Japanese Red Cross Katsushika Maternity Hospital were enrolled in this study. They were divided into 2 groups by randomization: (1) an L gro...

Intestinal barrier function in pigs after weaning is almost exclusively determined in terminal experiments with Ussing chambers. Alternatively, the recovery in urine of orally administered lactulose can be used to assess intestinal permeability in living animals. This experiment was designed to study the barrier function of the small intestine of pigs over time after weaning. The aim was to rel...

Milk concentration permeate (MCP), a low-value by-product of ultrafiltration plants and calcium carbonate-based catalysts were used for lactulose production. The results obtained show the effectiveness of oyster shell powder and limestone for lactose isomerisation as a replacement for egg shell powder. With the reaction conditions of 12mg/ml catalyst loading, reflux time of 120min at 96°C, a ma...

For some time now prebiotics have been proposed to improve health by stimulation of beneficial bacteria in the intestine of humans and animals. The current study is aiming to show effects of feeding of either 2% inulin or 2% lactulose in milk replacer on performance and intestinal morphology of male Holstein-Friesian calves. After 20 weeks of feeding inulin led to significantly higher daily wei...

INTRODUCTION Lactulose is a prebiotic with bifidogenic and urea reduction effects. It can improve Bifidobacteria and Lactobacilli counts in healthy humans and it may possibly have similar effects in chronic kidney disease (CKD) patients. OBJECTIVES To investigate the effect of lactulose on fecal microflora of patients with CKD. PATIENTS AND METHODS Thirty-two patients with stages 3 and 4 of...
