This study tested whether a daily probiotic capsule containing two bacterial strains could reduce gastrointestinal symptoms like bloating, gas, and cramps in adults with lactose intolerance and methanogenic intestinal overgrowth. Twenty-two adults took either the probiotic or a p…

This study looked at whether cutting out certain carbs (FODMAPs) can help people with celiac disease who still have stomach issues even after following a gluten-free diet. Researchers surveyed and then ran a controlled trial with 80 adults who had celiac disease and irritable bow…

This study tested whether a low-immunogenic oat variety called Saul is well-tolerated by adults with celiac disease who are in remission. Forty participants ate 50 grams of gluten-free Saul oat flakes daily for 14 days. Researchers tracked symptoms and blood markers to see if the…

This study tested whether adding lactase enzyme to milk feedings helps preterm babies (born before 34 weeks) digest better and gain weight. 124 infants received either lactase-supplemented or standard feedings for two weeks. Researchers tracked feeding tolerance, weight gain, and…

This study tested a drug called PRV-015 in 388 adults with celiac disease who still had symptoms like belly pain and bloating even after following a strict gluten-free diet. The goal was to see if the drug could reduce these symptoms better than a placebo. Participants took the d…

This study is collecting blood, urine, and stool samples from 500 children with autoimmune diseases and healthy controls. Researchers will analyze these samples to find molecular patterns that could help diagnose these conditions and guide treatment decisions. The goal is to crea…

This study collects tissue and blood samples from 300 people with autoimmune diseases like Crohn's, multiple sclerosis, and celiac disease. Researchers aim to identify the specific targets of immune cells (T cells) that cause inflammation. The goal is to discover new targets for …

Researchers are testing whether two types of bariatric surgery, Roux-en-Y gastric bypass and sleeve gastrectomy, reduce how much dietary protein older adults digest. The study compares adults aged 65 and older who had surgery 1 to 10 years ago with younger adults and with people …
