Disaccharidase Enzyme Deficiency in Adult Patients with Gas and Bloating.

Introduction: Disaccharidases produced by the small intestinal brush border facilitate digestion of dietary carbohydrates. If deficient, they can cause carbohydrate malabsorption resulting in several abdominal symptoms. Our aim was to examine the prevalence of disaccharidase deficiency and correlate this with abdominal symptoms in adult patients with chronic abdominal symptoms.

Intestinal Disaccharidase Deficiency in Adults: Evaluation and Treatment.

Purpose Of Review: Disaccharidase deficiency in adults causes carbohydrate malabsorption, resulting in symptoms which significantly overlap with irritable bowel syndrome (IBS). This article discusses the diagnosis and treatment of disaccharidase deficiency within the context of recent literature.

Recent Findings: Disaccharidase deficiency in adults is more common than previously thought, which includes lactase, sucrase, maltase and isomaltase enzymes.

Profile of plecanatide in the treatment of chronic idiopathic constipation: design, development, and place in therapy.

Constipation is a multifactorial disorder that can cause significant psychological distress to patients and economic burden on the health care system. Many patients are not satisfied with their current established treatment, highlighting the need for new and improved therapeutic options. Guanylate cyclase-C (GC-C)/cyclic guanosine monophosphate agonists have emerged as a safe and efficacious class of drugs for the treatment of chronic idiopathic constipation (CIC).

Rome IV Diagnostic Questionnaires and Tables for Investigators and Clinicians.

The Rome IV Diagnostic Questionnaires were developed to screen for functional gastrointestinal disorders (FGIDs), serve as inclusion criteria in clinical trials, and support epidemiological surveys. Separate questionnaires were developed for adults, children/adolescents, and infants/toddlers. For the adult questionnaire, we first surveyed 1,162 adults without gastrointestinal disorders, and recommended the 90 percentile symptom frequency as the threshold for defining what is abnormal.
