Insights

Chronic unexplained hypertransaminasemia, elevated liver enzymes, is more common in celiac disease (CD) than tropical sprue (TS) or irritable bowel syndrome (IBS). Gluten and tissue transglutaminase (tTG) may uniquely cause liver issues in CD.

Area of Science:

  • Gastroenterology
  • Hepatology
  • Immunology

Background:

  • Unexplained hypertransaminasemia is a recognized manifestation of celiac disease (CD).
  • Similarities in intestinal injury patterns exist between CD, tropical sprue (TS), and irritable bowel syndrome (IBS).
  • Existing knowledge does not fully explain liver involvement in CD solely based on intestinal damage.

Purpose of the Study:

  • To investigate the underlying mechanisms of hypertransaminasemia in celiac disease.
  • To explore factors contributing to liver involvement in CD beyond intestinal mucosal damage.
  • To differentiate the causes of hypertransaminasemia in CD compared to TS and IBS-D.

Main Methods:

  • Comparative analysis of hypertransaminasemia frequency in CD, TS, and IBS-D patients.
  • Review of existing literature on intestinal injury, permeability, and inflammation in these conditions.
  • Hypothesis formulation based on unique factors in CD, including gluten toxicity and tissue transglutaminase (tTG).

Main Results:

  • Hypertransaminasemia occurs significantly more frequently in CD than in TS and IBS-D.
  • Intestinal mucosal damage, permeability, and inflammation alone do not fully account for liver damage in CD.
  • Gluten toxicity and tTG are proposed as unique contributing factors to hypertransaminasemia in CD.

Conclusions:

  • Factors beyond intestinal damage, specifically gluten toxicity and tissue transglutaminase (tTG), are hypothesized to cause hypertransaminasemia in celiac disease.
  • Further research is needed to elucidate the hepatic toxicity mechanisms of gluten and tTG.
  • Understanding the role of pro-inflammatory cytokines in the entero-hepatic circulation is crucial for explaining liver involvement in CD.

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Acute Pancreatitis II: Pathophysiology01:21

Acute Pancreatitis II: Pathophysiology

The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
Chronic Pancreatitis I: Introduction01:25

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...

Chronic Pancreatitis II: Pathophysiology

Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...
