Abstract:
Pegylated (PEG)-asparaginase is used during the induction and intensification phases of treatment for B-cell acute lymphoblastic leukemia (B-ALL). It works by depleting the external sources of asparagine, causing the death of lymphoblasts. It has several adverse effects, including pancreatitis and hypertriglyceridemia; however, the simultaneous occurrence of both is uncommon. We present the case of an 18-year-old man with B-ALL who developed acute epigastric pain radiating to the back and non-bloody, non-bilious emesis following treatment with PEG-asparaginase. He was diagnosed with acute interstitial pancreatitis and severe hypertriglyceridemia. Conservative management was used for the pancreatitis, while hypertriglyceridemia was treated with an insulin infusion. Pancreatic toxicity and hypertriglyceridemia can necessitate the discontinuation of PEG-asparaginase, limiting treatment options and potentially increasing the risk of relapse. Therefore, further studies are needed to identify the factors contributing to hypertriglyceridemia and pancreatitis, aiding clinicians in monitoring and prevention.

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:

01:24Chronic 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...

01:17Gastritis-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...
