What Does Lipase Do In The Pancreas – Pancreatitis review of causes, symptoms, location of pain, diagnosis, treatment, diet and pathophysiology. Great for nurses, students, medical students, USMLE and NCLEX!

But what exactly is pancreatitis? What cause? What are the symptoms? How is it diagnosed and treated? Can dietary changes help?

What Does Lipase Do In The Pancreas

In this post, we will go through the characteristics of pancreatitis including definition, types, causes, symptoms, diagnosis and treatment.

Pancreatic Panniculitis And Elevated Serum Lipase In Metastasized Acinar Cell Carcinoma Of The Pancreas: A Case Report And Review Of Literature

The pancreas is an organ located in the upper abdomen behind the stomach, and extends into the left upper quadrant (LUQ).

The image below shows the pancreas highlighted in red and moved to the front of the stomach for better visualization.

Pancreatic digestive enzymes are released in the duodenum, the first part of the small intestine, to aid in the digestion of fats (lipases), carbohydrates/starches (amylases) and proteins (proteases).

Note: Gastrin is mainly produced in the stomach, but can also be produced in the duodenum and pancreas.

Significant Elevations Of Serum Lipase Not Caused By Pancreatitis: A Systematic Review.

Pancreatic hormones are released into the blood to help control glucose (insulin, glucagon, somatostatin and amylin) and digestion (gastrin).

Pancreatitis: The pancreas (star) is located in the upper abdomen behind the stomach (moved to the front of the stomach for visualization), and extends into the LUQ.

Pancreatitis occurs when the aforementioned digestive enzymes are activated prematurely in the pancreas compared to the small intestine.

There are many different causes for premature activation of pancreatic enzymes including obstruction, gallstones, alcohol, etc. – more on this soon!

Pancreatitis: The pancreas (star) is located in the upper abdomen and extends into the LUQ. Premature activation of pancreatic digestive enzymes in the pancreas causes inflammation. There are 2 main types of pancreatitis – Acute vs Chronic.

While the onset of acute pancreatitis is often sudden and severe, it is short-lived with a duration of days to weeks before resolving.

Pancreatic enzymes are usually elevated since active inflammation is present, and this can be measured with a blood test – more on that soon!

In most cases of acute pancreatitis there is no long-term damage to the pancreas, especially if the episode is mild and uncomplicated.

Chronic pancreatitis can lead to fibrosis or calcification of the pancreas, and this can negatively affect its function in digestion and glucose control.

While the symptoms of acute pancreatitis are often sudden and severe, the presence and severity of symptoms in chronic pancreatitis can fluctuate.

Compared to acute pancreatitis (days-weeks), chronic pancreatitis is long-lasting and can persist for several months to years.

Chronic pancreatitis can be caused by recurrent episodes of acute pancreatitis, continued alcohol abuse, and hereditary conditions and diseases such as cystic fibrosis.

If you are a medical student, these 3 causes are commonly tested on the medical board and license exams.

Questions related to pancreatitis often have a patient with a history of gallstones, alcohol abuse, or high triglyceride levels.

If you are a medical student, the description “epigastric or left upper quadrant abdominal pain radiating to the back” is a buzzword phrase for pancreatitis in exams.

Question stems for pancreatitis will often have a patient with a history of gallstones, alcohol use, or hypertriglyceridemia that present epigastric abdominal pain radiating to the back.

Pancreatitis Nursing Care And Management: Study Guide

Pancreatitis symptoms: Abdominal pain is usually located in the epigastric / LUQ region, radiates to the back, is worse after eating and lying supine, and can improve with leaning forward. Nausea, vomiting, and decreased appetite may also be present.

Abdominal tenderness or guarding is often present on physical examination, especially in the epigastric regions or the left upper quadrant.

Jaundice, a yellowing of the skin and the sclera of the eyes, can indicate the presence of a biliary obstruction.

Vital signs may also be abnormal, including elevated temperature, tachycardia or fast heart rate, and hypotension or low blood pressure.

Human Pancreatic Exocrine Response To Nutrients In Health And Disease

Inflammation of the pancreas can cause increased levels of lipase in the blood, which can be measured on blood tests.

However, lipase and amylase levels may be normal in chronic pancreatitis due to chronic damage and fibrosis to the pancreas.

If lipase is elevated and there is abdominal pain consistent with pancreatitis, pancreatitis is a likely diagnosis.

Remember that the pain is often strong and severe, located in the epigastric region or upper left quadrant, and radiates to the back.

It is important to note that abdominal imaging is not necessary to make the diagnosis of pancreatitis in most cases, especially in moderate uncomplicated cases.

If there is a concern for underlying pathology or complications that would require imaging, then imaging should be considered.

Diagnosis of Pancreatitis: At least 2 of the 3 is indicative of pancreatitis. 1. Elevated serum lipase. 2. Abdominal pain consistent with pancreatitis. 3. Abdominal imaging showing findings consistent with pancreatitis.

An AST to ALT ratio >2 is indicative of alcoholic liver disease, and could suggest alcohol abuse as an underlying cause of pancreatitis.

This may include a right upper quadrant ultrasound for gallstones, asking about alcohol use, or obtaining a serum triglyceride or ethanol level.

Other labs may include a metabolic panel, lactate, complete blood count, CRP, and stool studies especially with chronic pancreatitis.

Patients with pancreatitis cannot tolerate oral foods initially because of the pain, and may need to be NPO (nothing by mouth).

The diet usually begins as a clear, bland liquid diet with progression to a normal diet as the pancreatitis resolves.

Lipases: It’s Not Just Pancreatic Lipase! In: American Journal Of Veterinary Research Volume 83 Issue 8 (2022)

Biliary pancreatitis may require an intervention such as an ERCP (endoscopic retrograde cholangiopancreatography) to remove a gallstone that is obstructing the bile ducts.

If gallstones were the cause of pancreatitis, then a cholecystectomy may be recommended (removal of the gallbladder).

Education, treatment, and counseling may be needed to help with smoking and/or alcohol cessation, lifestyle modifications, changes to a low-fat diet, or changes to medications.

Remember a question about pancreatitis on medical examinations usually have a patient with a history of gallstones, alcohol use, or high levels of triglycerides presenting epigastric abdominal pain radiating to the back.

Lipases are enzymes responsible for the conversion of triglycerides and other esterified substrates, they are involved in the basic metabolism of a large number of organisms, from a simple microorganism to mammals. They also have wide applicability in many fields of which industrial biotechnology, the production of cleaning agents and pharmacy are the most important. The use of lipase in analytical chemistry where it can serve as a part of biosensors or bioassays is an application of growing interest and has become another important use. This review is focused on the description of lipase chemistry, its current applications and methods for its analysis measurement. Examples of bioassays and biosensors, including their physical and chemical principles, performances for specific substrates, and discussion of their relevance, are given in this work.

While standard analytical methods and devices for various assays are common in laboratories and specialized workplaces, a single reliable portable analysis device is not able to cover the entire spectrum of analytes that are measured for diagnostic purposes, environmental, technological and others. Therefore, manual devices for the most relevant analytes are required. Most biosensors
