Abstract:
Protein loss enteropathy (PLE) is a complex disease process that can result in potentially fatal protein losses. Gastrointestinal protein losses usually arise from damage to the gastrointestinal mucosa or from lymphatic obstruction. The goal of management is to identify and treat the underlying causes and maintain normal serum protein levels. Here, we present a patient with diarrhea and generalized edema, with decreased serum albumin and gamma-globulin levels, concerning for protein loss enteropathy. He was ultimately found to be positive for HIV infection, and his stool alpha-1 antitrypsin levels were diagnostic of protein loss enteropathy. His endoscopic and histologic evaluation revealed gastric Epstein-Barr virus-encoded small RNA- (EBER-) positive lymphoma. Though gastrointestinal lymphomas are known to cause PLE, this will be the first documented case of EBER-positive gastric lymphoma presenting with PLE. We hope to bring awareness to this unique presentation to aid in expedient diagnosis and treatment to avoid delays in treatment and potentially fatal outcomes.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
