View clinical trials related to Lactose Malabsorption.
Filter by:Irritable bowel syndrome (IBS) is a functional gastrointestinal disease. There is no well-defined pharmacological treatment. This clinical trial is a prospective, double-blind, two-armed randomized controlled, single-center trial. It is created to examine the role of IBS in patients with lactose intolerance. IBS patients undergo lactose H2 breath test (LHBT) and lactose tolerance test (LTT). Those with positive LTT and LHBT will be randomized into two groups: alverine-citrate + simethicone and lactase group (1) or alverin-citrate + simethicone with the placebo group (2). The goal of this study is to compare the lactase enzyme with placebo in IBS patients with lactose intolerance.
Milk is the source of high-quality protein, calcium, and other vitamins and minerals. Epidemiologic studies have linked high consumption of milk with risk of metabolic syndrome, T2DM, hypertension and obesity, which are independent risk factors of cardiovascular disease. However, milk contains disaccharide lactose, which may cause gastrointestinal problems in those adults with poor digestion. Recent studies have shown that subjects with intolerance to lactose tend to reduce their consumption of milk. Actually, consumption of 12g lactose (240ml milk) per day produces negligible symptoms in lactose intolerant. Furthermore, a dairy-rich diet could improve lactose intolerance because of colonic adaption to it. Lactose maldigestion would not be a restricting factor in milk intake. In general, the undigested lactose will be fermented by colonic bacteria into hydrogen, carbon dioxide, and short-chain fatty acids (SCFA: acetate, propionate, and butyrate). The SCFAs may have beneficial effects on human glucose and lipid metabolism, and the lactose fermentation may change the intestinal flora profile. But there are few studies evaluating effect of milk intake on health of people with lactose malabsorption or intolerance.This trial intend to study the effect of whole milk on cardio-metabolic risk factors of healthy person with or without lactose maldigestion.
Fermented dairy products, especially real Yoghurt, are often tolerated better by lactose malabsorbers than unfermented dairy products. The intake of dietary supplements containing acid Lactase derived from Aspergillus oryzae with lactose containing foodstuffs is known to reduce/alleviate symptoms of lactose intolerance in lactose malabsorbers. The study aims to compare the effect of the intake of a combination of yoghurt bacteria and acid lactase to the effect of yogurt bacteria or acid lactase alone on the lactose digestion in lactose malabsorbers. It is hypothized that the combination preparation will be more effective and/or will show a more reliable effect than the two mono-preparations.
