Protein-losing enteropathy (PLE) is a rare syndrome of gastrointestinal protein loss that may complicate a variety of diseases. The primary causes can be divided into erosive gastrointestinal disorders, nonerosive gastrointestinal disorders, and disorders involving increased central venous pressure or mesenteric lymphatic obstruction. Herein, we report on a 65-year-old man with PLE caused by in...
Protein-losing enteropathy (PLE) is a rare complication of intestinal diseases. Its main manifestation is hypoproteinemic edema. The diagnosis of PLE is based on the verification of protein loss into the intestinal lumen, by determining fecal α1-antitrypsin concentration and clearance. The localization of the affected colonic segment is clarified using radiologic and endoscopic techniques. The ...
After speculation in the literature about the nature of Personal Learning Environments, research in the design and development of PLEs is now in progress. This paper will report on the first phase of research in a PLE, the identification process, of what potential users would find important components, applications and tools on a PLE. The methodology includes surveying “super-users” on their us...
Protein-losing enteropathy (PLE) is a debilitating potential complication of ulcerative colitis (UC). We report a case of PLE in a 26-year-old male patient with UC. The patient lost 50 pounds in the setting of a UC flare and was found to have an albumin level of 1.2 g/dl. Although the patient's UC was clinically controlled with steroids, the weight loss and hypoalbuminemia persisted with the pa...
This report describes two patients with sporadic lymphangioleiomyomatosis complicated by protein-losing enteropathy (PLE). Imaging studies indicated retroperitoneal lymphangioleiomyomas and abnormalities of the adjacent digestive tract. Endoscopic mucosal biopsy revealed colonic lymphangiectasia in one patient; whereas the site in the other patient was intestinal. Treatment with sirolimus led t...
Protein losing enteropathy (PLE), defined as severe loss of serum protein into the intestine, occurs in 4-13% of patients after the Fontan procedure and carries a dismal prognosis with a five year survival between 46% and 59%. Chronically raised systemic venous pressure is thought to be responsible for the development of PLE in these patients, with perhaps superimposed immunological or inflamma...
In the present study, we examined the influence of preload augmentation via passive leg elevation (PLE) on synthesized aortic blood pressure, aortic augmentation index (AIx), and aortic capacitance (a reflection of aortic reservoir function). Central and peripheral hemodynamics were measured via tonometry with a generalized transfer function in 14 young, healthy men (age = 24 yr). Aortic blood ...
