Complications of Liver Failure: A Case Study
Clinical Situation 4: Liver Failure Case Study
77-Year-Old Male with Aggravated Liver Failure
Background:
- Liver failure from cirrhosis of enolic origin.
- Upper gastrointestinal bleeding from esophageal varices 2 months ago.
- Poorly controlled type 2 diabetes mellitus.
Evolution (Day 2 of Admission):
- Drowsiness and confusion, disorientation in space and time, not recognizing family members.
- Prostrate, remains in bed all day but moves independently within the bed.
- Increased waist circumference (2.5 cm from admission)
Lipids, Cell Biology, and Immunology Overview
Lipids
Properties and Classification
Lipids are organic molecules composed of carbon, hydrogen, and oxygen. Some complex lipids also contain nitrogen, phosphorus, or sulfur. Key properties include insolubility in water, solubility in organic solvents, and low density.
Lipids are classified into:
- Fatty acids
- Saponifiable lipids:
- Simple: Triacylglycerols and waxes
- Complex: Phosphoglycerides and sphingolipids
- Non-saponifiable lipids:
- Steroids
- Terpenes
- Icosanoids
Cholesterol
Cholesterol, a sterol, is present in

Peroxisomes: Structure, Function, and Associated Diseases
Peroxisomes. In 1954, Rhodin found small organelles in the proximal tubule of mouse kidneys, which he called “microbodies.” In 1962, Novikoff discovered microperoxisomes. These self-replicating organelles, bound by a single membrane, are present in all eukaryotic cells. They contain enzymes and are involved in:
- Control of lipid homeostasis by beta-oxidation
- Conversion of cholesterol into bile salts (liver only)
- Plasmalogen biosynthesis
- Cellular respiration
- In plants, seed peroxisomes convert fatty acids
Cell Biology: Structure, Types, and Organization
1. The Cell: The Building Block of Life
Organic and inorganic compounds group together to form cells. All living things are composed of one or more living cells. The cell is the smallest unit capable of performing three vital functions: nutrition, interaction, and reproduction.
Human cells are eukaryotic, meaning their genetic material (DNA) is housed within a double-membraned nucleus. The cytoplasm is compartmentalized into numerous organelles, each performing specialized functions. While human
