Study Notes
Clinical Enzymology Overview
- Biochemical investigations are essential for diagnosing and monitoring disease progression.
- Enzymes act as catalysts, accelerating chemical reactions without being consumed.
- Enzymes are classified based on the reactions they catalyze, with the suffix "-ase".
- Isoenzymes are different molecular forms of an enzyme that catalyze the same reaction, often with different tissue distribution.
- Measuring enzyme levels in blood can indicate tissue damage and disease processes.
Enzyme Measurement Principles
- Enzyme activity is measured by monitoring the rate of conversion of a substrate to a product.
- Coupled reactions are often used to amplify signal detection and enhance sensitivity.
- Isoenzymes can be separated using electrophoresis, differential activity, or other properties like heat stability.
Myocardial Infarction Biomarkers
- Creatine Kinase (CK) is a key enzyme in energy production found in skeletal and cardiac muscle.
- CK levels rise in the blood following myocardial infarction (MI) due to damage to heart muscle.
- CK-MB isoenzyme is specific to heart muscle and its elevation confirms MI.
Liver Disease Investigations
- Liver function tests assess damage, synthetic function, conjugation capacity, and cholestasis.
- Aspartate transaminase (AST) and alanine transaminase (ALT) are enzymes released into the blood from damaged liver cells.
- ALT is more specific for liver damage than AST.
- Alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) levels are elevated in cholestasis, indicating a blockage in bile flow.
Common Clinical Chemistry Techniques
- Spectrophotometry is a widely used technique that measures light absorption by analytes.
- Immunoassays utilize antibodies to detect and quantify specific analytes in biological samples.
- Chromatography separates and analyzes different components in a sample based on their affinity for a stationary phase.
Techniques: Spectrophotometry, Immunoassays and Chromatography
- Spectrophotometry relies on the Beer-Lambert Law, relating light absorption to analyte concentration, which is essential for quantitative analysis.
- Immunoassays offer high sensitivity and specificity by leveraging the binding affinity of antibodies to target molecules.
- Chromatography, particularly High Performance Liquid Chromatography (HPLC), enables separation and quantification of different compounds in complex mixtures.
Patient Management and Clinical Biochemistry
- Diagnosis, treatment, and monitoring of disease are all essential aspects of patient management.
- Clinical biochemistry plays a crucial role in all these areas with the help of biochemical investigations.
Use of Clinical Chemistry
- Clinical chemistry is used for screening, diagnosis, monitoring, and prognosis of diseases.
Principle Uses of Biochemical Tests
- Screening: Detecting sub-clinical disease before symptoms appear (e.g., Phenylketonuria (PKU)).
- Diagnosis: Confirming or rejecting clinical diagnoses (e.g., cardiac troponin T and I (cTnT and cTnI) for myocardial infarction).
- Monitoring: Tracking the natural history of a disease or response to treatment (e.g., therapeutic drug monitoring (TDM) or glucose levels in diabetes).
- Prognosis: Providing information about the likely outcome of the disease (e.g., serum cholesterol levels in coronary artery disease (CAD)).
Cellular Damage
- When cells are damaged, their contents, including enzymes, leak out into the bloodstream.
- Measuring enzyme levels in blood can be a sensitive indicator of tissue damage.
Duchenne Muscular Dystrophy (DMD)
- DMD involves progressive muscle degeneration due to the breakdown of myocytes.
- The leakage of myocyte contents, including creatine kinase (CK), into the blood results in elevated plasma CK activity, often 10 times higher than normal.
Creatine Kinase (CK)
- CK is an enzyme involved in energy production, found in high concentrations in skeletal and cardiac muscle.
- CK activity is usually present in blood due to normal skeletal muscle turnover.
CK and DMD
- Elevated CK levels are a hallmark of DMD and can be used for diagnosis.
- Carrier females of the DMD gene often have elevated CK levels.
Other Causes of Muscle Damage
- Besides DMD, several other factors can cause muscle damage, leading to elevated CK levels:
- Excessive exercise (marathon runners, army recruits)
- Surgery
- Skeletal muscle trauma
- Drug-induced damage (e.g., cocaine)
General Principles of Enzyme Measurement
- Enzymes act as catalysts, increasing the rate of chemical reactions without being consumed.
- Measuring enzyme activity can be achieved through coupled reactions that involve a sequence of reactions, where the product of one reaction serves as the substrate for the next.
- The enzyme's activity can be measured by monitoring a change in absorbance, fluorescence, or other detectable properties.
Creatine Kinase Assay
- The total CK assay measures all CK activity present in a sample.
- The coupled reaction involves a series of steps:
- CK converts creatine phosphate to creatine, releasing ADP.
- ADP is used in the phosphorylation of glucose by hexokinase.
- The production of NADPH is monitored by the absorbance change at 340 nm.
Myocardial Infarction (MI)
- MI is the death of heart tissue due to blockage of a coronary artery caused by a blood clot.
- The resulting infarct is an area of dead tissue.
Plasma Enzyme Activity Following MI
- Enzyme levels in plasma change following MI.
- CK activity rises rapidly and peaks within 12-24 hours after infarction.
- CK activity can remain elevated for 2-3 days.
Total Creatine Kinase and Isoenzymes
- Total CK activity reflects the overall CK activity in a sample, including all CK isoenzymes.
- Isoenzymes are different molecular forms of the same enzyme with similar functionality but differ in their structure and tissue specificity.
CK Isoenzymes
- CK isoenzymes are classified based on their tissue distribution.
- CK-MM is primarily found in skeletal muscle.
- CK-MB is predominantly found in heart muscle.
Electrophoresis of CK Isoenzymes
- Electrophoresis can separate CK isoenzymes based on their charge and size.
- Immunological methods can detect both active and inactive CK forms.
CK Isoenzyme Changes Following MI
- Following MI, an increase in CK-MB levels indicates heart muscle damage.
- CK-MM levels are mainly elevated after skeletal muscle damage.
Commonly Used Biochemical Techniques
- Spectrophotometry is a widely used technique to measure the absorbance of solutions at specific wavelengths.
- Other photometric techniques like turbidimetry, fluorometry, and chemiluminescence are also employed.
- Immunoassays use antibodies to detect and quantify specific analytes.
- Chromatographic techniques, like thin-layer chromatography (TLC) and liquid chromatography (LC), separate and identify different analytes based on their physical and chemical properties.
Reduction in NAD
- NADH production during an enzyme-catalyzed reaction can be monitored by measuring the absorbance change at 340 nm.
Immunoassays
- Immunoassays are widely used in clinical chemistry due to their high sensitivity and specificity, particularly with modern technologies.
Chromatography
- Chromatography methods, especially TLC and HPLC, separate and identify analytes based on their different affinities for the stationary and mobile phases.
- They are versatile for separating and quantifying various compounds, including metabolites, drugs, and proteins.
Patient Management and Clinical Biochemistry
- Biochemical investigations can be used for diagnosis, monitoring disease progression and treatment
- Clinical biochemistry plays a vital role in patient management
Clinical Chemistry
- Biochemical tests are used for screening, diagnosis, monitoring and prognosis
- Most analytes (proteins, enzymes or other molecules) used in diagnosis depend on the high concentration of that substance within the cell relative to that in plasma.
Myocardial Infarction
- Infarction is death of part or the whole of an organ that occurs when the artery carrying its blood supply is obstructed by a blood clot.
- Infarct: small localised area of dead tissue thus produced.
- Creatine kinase (CK) levels are measured in plasma following a suspected myocardial infarction.
- Measuring the total CK activity in a plasma specimen allows for assessment of skeletal muscle damage and cardiac damage
Enzymes and Isoenzymes
- Isoenzymes are different molecules that catalyze the same reaction
- Isoenzymes have tissue-specific expression
- Isoenzymes have cellular localization within specific organelles
- Different isoenzymes can be formed from different combinations of subunits
- Isoenzymes display different electrophoretic mobility
- Isoenzymes have varying activity under different reaction conditions
Creatine Kinase (CK)
- CK is a dimer
- CK isoenzymes have tissue-specific expression
- CK-MB isoenzyme is a good indicator of cardiac damage
- CK-MM isoenzyme is a good indicator of skeletal muscle damage
Plasma Enzyme Activities
- Plasma enzyme levels depend on the:
- rate of release from damaged cells
- rate of damage to cells
- extent of cell damage
- rate of cell proliferation (malignancy)
- degree of induction of enzyme synthesis
- rate of clearance from circulation
