The intestinal permeability refers to the property of the membranes of the intestinal tract to allow the traffic of different macromolecules. Increased intestinal permeability is present in individuals with: allergy and/or food intolerance, celiac disease, intestinal diseases (e.g. Crohn’s disease), and systemic diseases (such as rheumatoid arthritis, ankylosing spondylitis, type 1 diabetes, IgA nephropathy, multiple sclerosis, chronic dermatological pathologies, asthma and various types of cancers). Decreased intestinal permeability can cause malabsorption and lead to malnutrition, even with a normal diet (whether in terms of quality or quantity). The identification of a change in intestinal permeability (whether in excess or lack) allows the therapeutic action in a specific way, with consequent improvement of the symptoms in a high percentage of patients.
The PI Exam is a noninvasive method that evaluates the integrity and functionality of the intestinal mucosa, which provides assistance in the diagnosis of the causes of a wide variety of intestinal and systemic symptoms, as well as providing information on the therapeutic response and clinical follow-up (activity and prognosis markers). The analysis consists of the administration of non-metabolizable substances of different molecular weights, such as lactulose and mannitol, by oral overload. The quantification by gas chromatography of the percentage of elimination of both substances in the urine informs its absorption.
