TH1 and TH2 Cytokine Profiles as Predictors of Severity in Acute Pancreatitis
Objectives:
Acute pancreatitis (AP) is severe in up to 20% of patients, with a high mortality rate. Quantification of serum TH1 and TH2 cytokines may provide objective evidence to assess the severity of AP and predict its course.
Methods:
One hundred seventeen patients were studied, measuring serum concentrations of interleukin (IL)1β, IL2, IL4, IL5, IL6, IL10, IL12p70, IL13, IL18, granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon (IFN) γ, and tumor necrosis factor (TNF) α.
Results:
Significant differences were found between patients with severe AP and those with mild or moderately severe AP in IFN-γ (P < 0.001), IL6 (P < 0.001), TNF-α (P = 0.002), GM-CSF (P < 0.001), IL4 (P = 0.002), IL1b (P = 0.017), and IL13 (P < 0.001) concentrations. Interferon-γ, IL6, and TNF-α were associated with severe AP, whereas GM-CSF, IL4, IL1b, and IL13 were associated with mild or moderately severe AP. The IL13/IFNγ ratio was significantly higher in patients with mild AP (P = 7.36 × 10).
Conclusions:
A TH1 profile was associated with severe AP and a TH2 profile with mild or moderately severe AP. We report an IL13/IFNγ ratio of potential value to predict the prognosis in AP.

01:27Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:30Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
01:26Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
01:24Chronic Pancreatitis I: Introduction
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...
