Summary
Insulin resistance is a key factor in type 2 diabetes and metabolic syndrome. This review analyzes various methods for measuring insulin sensitivity, from simple blood tests to complex clamp tests, to guide appropriate use.
Area of Science:
- Endocrinology
- Metabolic Research
- Public Health
Background:
- Insulin resistance is a significant public health concern.
- It is central to type 2 diabetes mellitus, cardiovascular risk, and metabolic syndrome.
- Accurate quantification of insulin sensitivity/resistance is crucial.
Purpose of the Study:
- To review and analyze commonly used methods for assessing insulin resistance.
- To guide the selection of appropriate methods based on required information and available resources.
- To determine the utility of different insulin resistance assays.
Main Methods:
- Analysis of various biological measurements for estimating insulin resistance.
- Comparison of simple indices (e.g., HOMA, QUICKI) using fasting blood samples.
- Evaluation of the gold-standard hyperinsulinaemic-euglycaemic clamp test in research settings.
Main Results:
- Multiple methods exist to estimate insulin resistance, varying in complexity and resource requirements.
- Simple indices offer basic assessment, while clamp tests provide precise measurements.
- Method selection depends on the specific research question and available resources.
Conclusions:
- Understanding the strengths and limitations of each method is essential for accurate assessment of insulin resistance.
- The choice of assay should align with the need for individual classification or group comparisons.
- This review provides insights into the appropriate application of different insulin resistance measurement techniques.

01:28Insulin: The Receptor and Signaling Pathways
Insulin action is mediated through a receptor tyrosine kinase, akin to the IGF-1 receptor. The number of receptors per cell varies significantly, from 40 on erythrocytes to 300,000 on adipocytes and hepatocytes. The insulin receptor consists of linked α/β subunit dimers, forming a heterotetramer glycoprotein with two extracellular α subunits and two β subunits spanning the membrane. The α subunits inhibit the inherent tyrosine kinase activity of the β subunits, but this inhibition is released...
01:16Insulin: Dosing Regimen and Adverse Effects
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

01:27Insulin Formulations: Types and Delivery
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.

01:25Insulin: Biosynthesis, Chemistry, and Preparation
The endoplasmic reticulum (ER) of pancreatic β-cells synthesizes preproinsulin, which consists of a signal peptide, A and B chains, and a C-peptide. Preproinsulin is then cleaved and folded into proinsulin, which translocates to the Golgi apparatus for sorting and packaging into secretory granules. In these granules, enzymatic clipping generates insulin and C-peptide.

01:26Oral Hypoglycemic Agents: Biguanides and Glitazones
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood glucose levels...
01:29Hyperglycemia
Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...
