Insulin: Dosing Regimen and Adverse Effects

Insulin: 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...

Oral Hypoglycemic Agents: Biguanides and Glitazones

Oral 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...

Dipeptidyl Peptidase 4 Inhibitors

Dipeptidyl Peptidase 4 Inhibitors

Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a significant...

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

Glucose Homeostasis: Pancreatic Islets and Insulin Secretion

The pancreatic islets comprising only 1%-2% of the volume are highly vascularized and innervated mini-organs. They contain five endocrine cell types, including β cells that secrete insulin, which is synthesized as a single polypeptide chain, preproinsulin, processed to proinsulin, and finally to insulin and C-peptide. This process is complex and regulated, involving the Golgi complex, the endoplasmic reticulum, and the secretory granules of the β cell.
Insulin and C-peptide are co-secreted in...

Glucagon-like Receptor Agonists

Glucagon-like Receptor Agonists

Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...

Oral Hypoglycemic Agents: Glinides

Oral Hypoglycemic Agents: Glinides

Repaglinide (Prandin) and Nateglinide (Starlix), known as glinides, are oral insulin secretagogues that stimulate insulin release from pancreatic β cells by closing the ATP-sensitive potassium channels (KATP channel). Repaglinide controls insulin release from pancreatic β cells by managing potassium efflux. It shares two binding sites with sulfonylureas and also has a unique site, indicating overlapping mechanisms of action. With a rapid onset and a 4-7 hour duration, it effectively manages...

Background:

Aging is associated with physiological degeneration, impacting carbohydrate metabolism and increasing insulin resistance.
Respiratory training is a potential intervention to mitigate age-related decline in cardiorespiratory, metabolic, and cognitive functions.
Insulin resistance is a significant metabolic challenge in the elderly population, affecting overall health and quality of life.

Purpose of the Study:

To investigate the effects of inspiratory muscular training using Threshold devices on insulin resistance in elderly individuals.
To assess the impact of targeted inspiratory muscle strengthening on metabolic markers related to carbohydrate metabolism.
To evaluate the potential of respiratory interventions in managing age-related metabolic dysfunction.

Main Methods:

A 12-week study involving 14 insulin-resistant elderly volunteers (aged 61-82).
Participants were divided into experimental and control groups, with the experimental group undertaking daily 30-minute inspiratory muscle training.
Insulin resistance was assessed using the homeostatic model assessment (HOMA).

Main Results:

The experimental group demonstrated significant improvements in insulin resistance.
Key findings included decreased glycemia (blood sugar) and reduced insulin requirements.
Enhanced respiratory force and performance were observed alongside a lower HOMA of insulin resistance.

Conclusions:

Inspiratory muscular training may improve insulin sensitivity in elderly patients diagnosed with insulin resistance.
While preliminary due to small sample size, findings suggest a beneficial role for respiratory exercise in metabolic health.
Further research is warranted to confirm these effects in larger cohorts.
