Summary
Obstructive jaundice (OJ) patients show significantly lower phospholipids and altered cholesterol compared to chronic viral hepatitis B (CVHB). Cancer-related OJ may be identified by low sphingomyelin levels.
Area of Science:
- Biochemistry
- Hepatology
- Oncology
Background:
- Obstructive jaundice (OJ) and chronic viral hepatitis B (CVHB) are distinct liver conditions.
- Serum lipid profiles can offer insights into liver disease pathophysiology.
Purpose of the Study:
- To compare serum lipid profiles in patients with obstructive jaundice (OJ) versus chronic viral hepatitis B (CVHB).
- To investigate lipid profile differences based on the etiology of OJ (cancer vs. gallstones).
Main Methods:
- Serum lipid profiles were analyzed in 50 OJ patients (20 cancer, 30 gallstones) and 30 CVHB patients.
- Key lipid components including phospholipids, cholesterol, and sphingomyelin were quantified.
Main Results:
- Patients with OJ exhibited half the relative serum phospholipid content compared to CVHB patients.
- Hyperlipidemia in OJ was primarily driven by free cholesterol or cholesterol esters.
- Cancer-related OJ patients showed lower sphingomyelin levels than those with gallstones or CVHB.
Conclusions:
- Serum lipid profiles differ significantly between OJ and CVHB.
- Altered cholesterol metabolism is characteristic of OJ.
- Low sphingomyelin may serve as a biomarker for detecting cancer-related obstructive jaundice.

Jaundice
Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
Blood Studies for Cardiovascular System III: Serum Lipid Profile
Understanding serum lipids is crucial for maintaining cardiovascular health and preventing heart disease and stroke.
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...

Asymmetric Lipid Bilayer
Biological membranes show uneven distribution of different types of lipids in the inner and outer layers, resulting in transverse asymmetric membranes. The treatment of the erythrocyte membrane with the enzyme phospholipase confirmed the asymmetric nature of the lipid bilayer. The enzyme hydrolyzes lipids into fatty acids and hydrophilic groups. The phospholipase acts only on the outer layer of the membrane, while the inner layer remains intact. The phospholipase treatment resulted in 80%...
Diseases of the Liver and Gallbladder
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

Lipid Absorption
Dietary triglycerides from chyme in the duodenum are mixed with bile salts produced by the liver to emulsify fats. As a result, large droplets are broken down into smaller ones, increasing the surface area for enzymatic action. Once emulsified, pancreatic lipases hydrolyze the triglycerides into free fatty acids and monoglycerides.
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...

Lipid-derived Compounds in the Human Body
Fats and lipids are crucial components in the human body. Some lipid-derived compounds, such as fat-soluble vitamins, eicosanoids, lipoproteins, and glycolipids, also play unique roles to support various biological processes .
Fat-soluble Vitamins
Fat-soluble vitamins, including vitamins A, D, E, and K, are required in minimal quantities, but their deficiencies can lead to severely abnormal physiological conditions. For example, vitamin A deficiency can cause night blindness, dry skin, delayed...
