Filter by:The goal of this clinical trial is to test whether a new combination of lactase and bacterial strain (L. Salivarius DSM 34078) can provide longer lasting beneficial effects on lactose digestion and gastrointestinal symptoms compared to lactase alone in people with lactose intolerance.
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.
Lactase is high in the newborn intestine, allowing him to digest the high amounts of lactose present in breastmilk. From weaning, lactase is genetically programmed to decrease, reaching residual levels in the adult. This situation occurs in 75% of the world population and is known as "adult primary hypolactasia" while the remaining 25% is "lactase persistent" i.e. maintains in adulthood lactase values similar to these of newborns. In subjects with hypolactasia, the intake of milk products can produce digestive symptoms, making that the affected individuals spontaneously reduce the consumption of these products and, therefore, their intake of calcium and proteins. In addition to lactose-free milk and exogenous lactase, a strategy for the intolerant subjects to continue consuming dairy products is, for example, to consume yogurt, due to the fact that the lactase of the yogurt bacteria continues to function in the intestine of the consumer, hydrolyzing lactose and decreasing the development of digestive symptoms. Similarly, many probiotic strains, such as L. acidophilus NCFM, L. casei CRL431, B. longum 401 and B. bifidum Orla Jensen 1424, express β-galactosidases that hydrolyze lactose, preventing its fermentation and the production of gases. The acute administration of these strains improves lactose tolerance. In addition, a recent study reported that dietary supplementation of intolerant subjects for 4 weeks with L. casei Shirota and B. breve Yakult reduced digestive symptoms and breath hydrogen excretion not only at the end of the period of administration of the probiotics but also 3 months after having discontinued the use of probiotics. Based on this background, the aim of this study is to determine whether the regular consumption of an ice cream with the strain B. bifidum 900791 improves lactose intolerance in hypolactasic subjects, even after the suspension of the consumption of the product. To determine if this effect is due to the adaptation of the microbiota, the investigators will also evaluate changes in the composition of the microbiota and the generation of volatile fatty acids.
Ritter Pharmaceuticals, Inc. is developing RP G28 as a treatment for Lactose Intolerance. Lactose intolerance is a syndrome of gastrointestinal symptoms resulting from a deficiency in intestinal lactase relative to the amount of lactose consumed. Efficacy of RP-G28 will be evaluated by the reduction of lactose intolerance-associated symptoms. The primary objective of this study is to assess the efficacy of RP G28 compared to placebo on symptom reduction related to lactose intolerance.
