IBS with constipation (IBS-C) accounts for approximately one-third of IBS cases and is associated with substantial burden of illness and decreased quality of life. This narrative review provides an overview of the current and upcoming treatment options and disease management for IBS-C from a US perspective and discusses the importance of the relationship between patient and health care provider in diagnosis and treatment. A positive diagnostic strategy for IBS-C is recommended, based on clinical history, physical examination, and minimal laboratory tests. An effective communication strategy between patients and health care professionals is essential to ensure early diagnosis and reduce both health care costs and overall disease burden. Treatment typically begins with lifestyle interventions and nonpharmacologic options, such as dietary interventions, fiber supplements, and osmotic laxatives. In patients with inadequate response to these therapies, 4 currently available therapies (lubiprostone, linaclotide, plecanatide, and tenapanor) approved by the US Food and Drug Administration may relieve IBS-C symptoms.

The presented case report is focused a 28-year-old male patient of Indian origin, temporarily living in Poland, who was diagnosed with an amoebic liver abscess. The patient presented with a range of non-specific symptoms including shortness of breath, chest pain, and fever. The differential diagnosis included cardio-pulmonary diseases, a range of tropical diseases such as malaria or typhoid fever, bacterial abscesses, and malignancies, necessitating a comprehensive, multi-modal diagnostic approach. This approach included an extensive review of patient history, physical examination, and various laboratory and imaging investigations. A further challenge in this case was the unavailability of standard cysticidal treatments in Poland, which required individualized therapeutic strategy. Despite these obstacles, the patient was successfully treated using an alternative regimen of intravenous metronidazole, ceftriaxone, doxycycline, chloroquine, and finally, trimethoprim/sulfamethoxazole (treatment with metronidazole was used as a base drug, due to the lack of typical cysticidal treatment, an alternative treatment was added: chloroquine is a recommended drug used in the treatment of pregnant patients, in addition, doxycycline showed in vitro activity against Entamoeba histolytica). This therapeutic journey underscored the value of adaptability in treatment protocols, particularly in regions where certain resources may not be readily available. This case report underlines the importance of broadening the differential diagnosis in non-endemic regions to include tropical diseases, particularly in the context of increasing global travel and migration. It also highlights the significance of employing comprehensive diagnostic strategies and adaptable treatment protocols in such scenarios. In addition, the report reiterates the need for global collaboration and education among healthcare providers to effectively manage tropical diseases, especially in non-endemic regions.

The layer of epithelial cells that lines the intestine is permeable to a limited degree, and the amount of paracellular permeability is tightly controlled to enable the absorption of ions, nutrients, and water from the lumen. Increased intestinal permeability to macromolecules can be triggered by a variety of insults, including infections, toxins from food poisoning, or allergens, which in turn cause an inflammatory response and are associated with abdominal pain in patients with IBS. This review article discusses increased intestinal permeability in IBS, focusing on IBS with constipation (IBS-C) through the lens of a patient case with a reported prior diagnosis of \"leaky gut syndrome\" upon initial contact with a gastrointestinal specialist. We review advantages and disadvantages of several methods of measuring intestinal permeability in patients and discuss when measuring intestinal permeability is appropriate in the therapeutic journey of patients with IBS-C. Furthermore, we discuss a possible mechanism of restoring the intestinal barrier to its healthy state through altering intracellular pH by inhibiting sodium-hydrogen exchanger isoform 3 (NHE3). Tenapanor is a minimally absorbed, small-molecule inhibitor of NHE3 that has been approved by the US Food and Drug Administration for the treatment of IBS-C in adults. Preclinical studies showed that tenapanor may restore the intestinal barrier in IBS-C by affecting the conformation of tight junction proteins via NHE3 inhibition to block the paracellular transport of macromolecules from the intestinal lumen. Testing for increased permeability in patients with IBS-C who experience abdominal pain may help inform the choice of therapeutics and alter patients' misconceptions about \"leaky gut syndrome\".</p>","PeriodicalId":10208,"journal":{"name":"Clinical and Experimental Gastroenterology","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11164200/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141300166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
