Study Notes
Overview of Acute Pancreatitis
- Acute pancreatitis is the inflammation of the pancreas.
- The pancreas is a heterochronic gland functioning as both an endocrine and exocrine gland, focusing mainly on its exocrine role in digestion.
Pancreatic Structure and Function
- The ductal system consists of main and accessory pancreatic ducts that transport digestive enzymes to the duodenum.
- Two major components of pancreatic secretions include digestive enzymes and a bicarbonate-rich fluid.
- Acinar cells produce digestive enzymes, while ductal cells secrete bicarbonate-rich fluid.
Enzyme Production
- Enzymes produced by acinar cells are stored as zymogens (inactive form) to prevent auto-digestion of the pancreas.
- Types of digestive enzymes:
- Lipases: Break down lipids.
- Amylases: Break down carbohydrates.
- Proteases: Break down proteins, kept inactive by protease inhibitors within granules.
Mechanism of Pancreatitis Development
- Pancreatitis develops when digestive enzyme secretion is altered, leading to autodigestion of pancreatic tissue.
- Two primary mechanisms:
- Obstruction of pancreatic ducts: Increases pressure, causing lysosomes to fuse with granules, activating proteases prematurely.
- Direct damage to acinar cells: Can release zymogens that activate inappropriately, causing tissue destruction.
Key Causes of Acute Pancreatitis
- Gallstones: Most common cause, obstructs the flow of digestive juices leading to activation of proteases.
-
Ethanol (Alcohol Abuse): Stimulates acinar cells and increases viscosity of secretions, leading to obstructions and autodigestion.
- Activates neutrophils that produce reactive oxygen species, destroying acinar cells.
- Trauma: Penetrating injuries directly damage acinar cells, leading to the release of zymogens.
- Hypertriglyceridemia: Elevated triglycerides can clog pancreatic capillaries, reducing oxygen supply and causing ischemic damage.
- Corticosteroids: Cause thick secretions from ductal cells, increasing the chance of duct obstruction.
- Mumps Virus: Directly affects both ductal and acinar cells, leading to cell destruction and enzyme activation.
- Autoimmune Conditions: Antibodies can damage ductal and acinar cells, facilitating activation of zymogens.
- Scorpion Stings: Rarely, toxins can destroy epithelial cells, leading to similar harmful effects as described above.
Summary
-
Acute pancreatitis is a serious inflammatory condition characterized by autodigestion of the pancreas due to various obstructions or cellular damage.
-
Understanding the anatomy and functions of pancreatic structures is critical for comprehending the pathophysiology of this condition.### Causes of Acute Pancreatitis
-
Drugs: Certain medications can lead to pancreatitis. Key drugs include:
- Sulfa Drugs: Examples like Bactrim and sulfasalazine.
- HIV Medications: Particularly NRTIs and protease inhibitors.
- Diabetic Medications: GLP-1 receptor agonists.
-
Endoscopic Retrograde Cholangiopancreatography (ERCP): A procedure used to diagnose and remove gallstones, which can lead to pancreatic tissue damage if complications arise during the process.
-
Hypercalcemia: Elevated calcium levels can stimulate pancreatic enzymes, leading to inadvertent activation and damage to pancreatic tissue.
Pathophysiology of Acute Pancreatitis
- Inflammation Process: Damage to the pancreas triggers an inflammatory response, which exacerbates tissue destruction and enzymatic activation.
- Digestive Enzyme Activation: Normally inactive enzymes in the pancreas should only activate in the duodenum, but certain conditions can lead to premature activation within the pancreas itself.
Symptoms of Acute Pancreatitis
-
Epigastric Abdominal Pain: The hallmark symptom, characterized by:
- Constant pain that radiates to the back.
- Worsens when lying supine and improves when leaning forward.
-
Nausea and Vomiting: Resulting from inflammation and potential obstruction of the digestive tract.
-
Jaundice: May occur if a gallstone obstructs the bile duct, leading to an accumulation of bilirubin in the bloodstream.
Complications of Acute Pancreatitis
-
Systemic Effects: Extensive inflammation can cause systemic complications, including:
- Hypotension: Due to vasodilation and fluid loss.
- Tachycardia: Reflex response to low blood pressure.
-
Disseminated Intravascular Coagulation (DIC): Characterized by widespread clotting within blood vessels leading to bleeding due to consumption of clotting factors.
-
Effects on Nearby Structures: Inflammation can compress adjacent structures like the duodenum, potentially causing:
- Abdominal Distension: Due to food blockage.
- Decreased Bowel Sounds: Reflecting reduced gastrointestinal motility.
Mnemonic for Causes of Acute Pancreatitis
-
"I GET SMASHED":
- I: Idiopathic
- G: Gallstones (most common cause)
- E: Ethanol (alcohol)
- T: Trauma
- S: Steroids
- M: Mumps virus
- A: Autoimmune conditions (e.g., SLE, rheumatoid arthritis)
- S: Scorpion bites (rare)
- H: Hypertriglyceridemia and hypercalcemia
- D: Drugs (sulfa, HIV medications) and ERCP.
Body Response to Inflammation
-
Vasodilation and Permeability Changes: Inflammatory mediators lead to:
- Widening blood vessels, causing lower systemic vascular resistance and blood pressure.
- Increased vessel permeability causing fluid leakage into tissues, resulting in edema.
-
Sympathetic Nervous System Activation: Reduced blood volume and pressure stimulate sympathetic responses, leading to increased heart rate.
-
Cytokine Release: Inflammatory mediators like IL-1, IL-6, and TNF-alpha can have systemic effects, including inducing fever and further affecting coagulation.### Complications of Pancreatitis
-
Body temperature increase can inhibit bacteria survival, leading to hypothalamus stimulation and fever.
-
Common clinical manifestations include hypotension and tachycardia.
-
Increased cytokine levels cause leukocytosis due to enhanced white blood cell production from bone marrow.
-
Liver responds to inflammation by producing acute phase reactant proteins; key proteins include C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR).
-
Elevated CRP and ESR indicate generalized inflammation.
-
Cytokines can lead to systemic vasodilation and increased capillary permeability, resulting in pulmonary edema, a serious complication from pancreatitis.
-
Severe pulmonary edema may lead to acute respiratory distress syndrome (ARDS), the leading cause of pancreatitis-related mortality.
-
In extreme cases, pancreatic necrosis can lead to fistula formation through the diaphragm, potentially causing pleural effusion.
Abdominal Complications
- Fluid accumulation in the abdomen from increased permeability results in ascites, leading to abdominal distension.
- Reduced effective arterial blood volume from hypotension can impair kidney perfusion, potentially causing pre-renal acute kidney injury (AKI).
Inflammatory Responses and Necrosis
- Damage to pancreas releases enzymes (proteases and lipases) that can cause liquefactive necrosis, breaking down peripancreatic fat.
- Free fatty acids released from fat breakdown can bind calcium, causing hypocalcemia through a saponification reaction.
- Inflammation can lead to fluid collections, forming encapsulated collections known as pancreatic pseudocysts.
- Pseudocysts can become infected, leading to pancreatic abscesses, characterized by fever, severe pain, and leukocytosis.
Vascular Complications
- Proteases from inflammation can damage blood vessels, possibly leading to hemorrhagic necrosis and significant bleeding.
- Retroperitoneal hemorrhage may present as Cullen's sign (bruising around the belly button) or Grey Turner’s sign (flank bruising), indicating serious vascular complications.
Diagnosis of Pancreatitis
- Classic symptoms include epigastric pain radiating to the back, worsening in supine position, along with nausea and vomiting.
- Risk factors include gallstones, alcohol use, and hypertriglyceridemia.
- Diagnosis confirmed through elevated lipase levels (> three times the upper limit of normal); amylase levels can also be elevated but are less specific.
- Imaging studies assist in assessing severity and identifying complications.
- Complete blood count (CBC) may show hemoconcentration due to plasma leakage, reflected as an elevated hematocrit.
- Signs of retroperitoneal bleeding may appear as low hemoglobin alongside elevated hematocrit.
Key Takeaways
- Monitoring for symptoms and laboratory changes is crucial in managing patients with pancreatitis.
- Awareness of potential complications can guide proper intervention and treatment strategies.
- Laboratory diagnostics, primarily lipase levels and imaging, play a critical role in confirming diagnosis and assessing severity.

- Nausea and Vomiting: Related to inflammation and possible digestive tract obstruction.
- Jaundice: Possible if a gallstone blocks the bile duct.
Complications of Acute Pancreatitis
-
Systemic Effects:
- Hypotension: Due to vasodilation and fluid loss.
- Tachycardia: Reflexive response to low blood pressure.
- Disseminated Intravascular Coagulation (DIC): Clotting disorder leading to bleeding.

Body Response to Inflammation
-
Vasodilation and Permeability Changes:
- Lowers systemic vascular resistance and blood pressure.
- Increases vessel permeability, causing tissue edema.
- Sympathetic Nervous System Activation: Increased heart rate due to reduced blood volume.
- Cytokine Release: Inflammatory mediators inducing systemic effects like fever.
Abdominal Complications
- Ascites leading to abdominal distension from fluid accumulation.
Inflammatory Responses and Necrosis
- Damage releases proteases and lipases, causing necrosis and fat breakdown.
- Free fatty acids bind calcium, resulting in hypocalcemia from saponification.
- Formation of pancreatic pseudocysts is possible, which can become infected.
Vascular Complications
- Inflammation-related protease damage may cause hemorrhagic necrosis and bleeding.
- Retroperitoneal hemorrhage may present as Cullen's sign or Grey Turner's sign.
Diagnosis of Pancreatitis
- Classic symptoms include epigastric pain radiating to the back, nausea, and vomiting.
- Risk factors: gallstones, alcohol, hypertriglyceridemia.
- Diagnosis confirmed with elevated lipase levels; amylase can also be elevated.
- Imaging and CBC can assess the severity and identify complications.
Key Takeaways
- Close monitoring for symptoms and laboratory changes is essential in managing pancreatitis.

Overview of Acute Pancreatitis
- Acute pancreatitis is an inflammatory condition affecting the pancreas, mainly its exocrine function.
- The pancreas functions as both an endocrine and exocrine gland but predominantly focuses on digestion through enzyme secretion.
Pancreatic Structure and Function
- The ductal system includes main and accessory pancreatic ducts that deliver digestive enzymes to the duodenum.
- Key components of pancreatic secretions:
- Digestive enzymes produced by acinar cells.
- Bicarbonate-rich fluid secreted by ductal cells.
Enzyme Production
- Digestive enzymes are stored as zymogens to avoid the autodigestion of pancreatic tissue.
- Types of digestive enzymes include:
- Lipases for lipid breakdown.
- Amylases for carbohydrate breakdown.
- Proteases for protein breakdown, controlled by protease inhibitors.
Mechanism of Pancreatitis Development
- Development occurs when enzyme secretion is altered, leading to autodigestion of pancreatic tissue.
- Mechanisms include:
- Obstruction of pancreatic ducts, causing pressure buildup and premature enzyme activation.
- Direct damage to acinar cells, allowing inappropriate zymogen activation.
Key Causes of Acute Pancreatitis
- Gallstones: Primary cause, obstructing digestive juice flow.
- Ethanol (Alcohol Abuse): Increases enzyme output and secretion viscosity.
- Trauma: Physical injury damages acinar cells.
- Hypertriglyceridemia: Clogs capillaries, leading to ischemic damage.
- Corticosteroids: Thickens secretions, raising duct obstruction risk.
- Mumps Virus: Harms both ductal and acinar cells.
- Autoimmune Conditions: Antibodies can lead to zymogen activation.
- Scorpion Stings: Rare cases leading to cell destruction.
Summary of Acute Pancreatitis
- Characterized by autodigestion of the pancreas due to obstructions or cellular damage.
- Knowledge of pancreatic anatomy and functions is vital for understanding the pathophysiology.
Causes of Acute Pancreatitis
- Certain drugs can induce pancreatitis, including:
- Sulfa Drugs: E.g., Bactrim.
- HIV Medications: NRTIs and protease inhibitors.
- Diabetic Medications: GLP-1 receptor agonists.
- ERCP: Can cause tissue damage during gallstone removal.
- Hypercalcemia: Elevated calcium stimulates enzyme activation.
Pathophysiology of Acute Pancreatitis
- Damage invokes an inflammatory response, exacerbating tissue destruction.
- Normally inactive enzymes may activate within the pancreas, leading to complications.
Symptoms of Acute Pancreatitis
- Epigastric Abdominal Pain: Constant, radiates to the back; worsens supine, improves leaning forward.
- Nausea and Vomiting: Related to inflammation and possible digestive tract obstruction.
