Congenital chloride diarrhea (CLD) is characterized by watery stools with high chloride content beginning prenatally and is inherited as an autosomal recessive trait. Perfusion studies have established a basic defect in ileal and colonic Cl-/HCO3- transport, resulting in defective chloride
Metabolic alkalosis is uncommon in infancy. Cystic fibrosis (CF) patients can develop dehydration because of sweat salt or gastrointestinal losses; with the correct salt supplementation, the electrolyte alterations can be reversed. Here, we present a CF patient with recurrent metabolic alkalosis,
A 3-year-old girl had severe intractable diarrhea with trichorrhexis nodosa and cirrhosis. This patient was referred to the pediatric dermatology clinic for lifelong brittle hair. The brittle hair microscopically demonstrated trichorrhexis nodosa. The girl also had facial dysmorphism, with a
Diarrhea is one of the most common adverse side effects observed in ∼7% of individuals consuming Food and Drug Administration (FDA)-approved drugs. The mechanism of how these drugs alter fluid secretion in the gut and induce diarrhea is not clearly understood. Several drugs are either substrates or
A 58-year-old woman with an 18-year history of primary biliary cirrhosis was admitted because of pneumococcal pneumonia. She was treated with antibiotics and mechanical ventilation. After the pneumonia improved, she developed severe watery diarrhea. Although vancomycin was administered enterally,
Four infants had noninfectious intractable diarrhea, vomiting, anasarca, hepatomegaly, hypoglycemia, and malnutrition within the first 3 months of life. Their parents originated from the same Northeastern part of Quebec, and consanguinity was found in two kindreds. Diarrhea was secretory in three
Nintedanib is an important drug for the treatment of idiopathic pulmonary fibrosis (IPF). However, the drug is discontinued in some patients who present with diarrhea. In this study, we aimed to assess the drug continuation rate in patients who developed diarrhea during nintedanib The cystic fibrosis transmembrane conductance regulator (CFTR) is a cAMP-regulated chloride channel localized primarily at the apical surfaces of epithelial cells lining airway, gut and exocrine glands, where it is responsible for transepithelial salt and water transport. Several human diseases are
A 52 year-old male patient with idiopathic hepatic cirrhosis complaining of diarrhea and weakness was accepted to the gastroenterology clinic. In order to find out the causative etiologic agent of diarrhea, stool samples were examined by different methods and stained using modified Kinyoun's
Heat-stable enterotoxin, produced by Escherichia coli, binds to particulate guanylate cyclase to increase cyclic GMP in intestinal cells. This in turn stimulates the cyclic-GMP- or cyclic-AMP-dependent protein kinase, activating the same chloride channel that is defective in cystic fibrosis. It is
SLC51A encodes the alpha subunit of the heteromeric organic solute transporter alpha-beta (OSTα-OSTβ), an important contributor to intestinal bile acid (BA) reabsorption in the enterohepatic circulation(1,2). Here, we identified the first case of OSTα deficiency in a child with unexplained elevated
