Abstract

Insights

Sodium glucose cotransporter2 (SGLT2) inhibitors effectively reduce insulin dosage and improve glycemic control in type 1 diabetes mellitus (T1DM). This analysis confirms their safety, showing no increased risk of hypoglycemia or diabetic ketoacidosis.

Area of Science:

  • Endocrinology
  • Metabolic Diseases
  • Pharmacology

Background:

  • Sodium glucose cotransporter2 (SGLT2) inhibitors are under investigation for type 1 diabetes mellitus (T1DM) treatment, with ongoing debate regarding their safety and efficacy.
  • This systematic evaluation addresses the controversial use of SGLT2 inhibitors in T1DM by analyzing existing randomized controlled trials (RCTs).

Approach:

  • A comprehensive literature search was conducted across six databases up to September 2022 to identify relevant RCTs.
  • 16 RCTs involving 7192 patients were included, with data extracted and analyzed using Cochrane risk bias assessment, Revman 5.4, and Stata 17.1.

Key Points:

  • SGLT2 inhibitors significantly reduced HbA1c, fasting plasma glucose, mean amplitude of glucose excursions, body weight, and total insulin dosage.
  • Crucially, SGLT2 inhibitors did not increase the risk of hypoglycemia, urinary tract infections, or diarrhea.
  • The observed benefits were achieved without compromising patient safety in the context of T1DM management.

Conclusions:

  • This meta-analysis demonstrates that SGLT2 inhibitors can reduce insulin requirements in T1DM patients.
  • The findings support the cautious use of SGLT2 inhibitors in T1DM, as they do not appear to elevate risks of hypoglycemia or diabetic ketoacidosis within a one-month period.

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 Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

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...

Secondary Active Transport01:55

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Diabetes: Management and Pharmacotherapy

The therapy for diabetes aims to alleviate hyperglycemia-related symptoms, prevent acute metabolic decompensation, and reduce chronic end-organ complications. Glycemic control is evaluated through short-term (self-monitoring, continuous glucose monitoring) and long-term (A1c, fructosamine) metrics, enabling near real-time tracking of blood glucose levels and reflecting glycemic control over specific time frames.
Insulin remains the cornerstone of treatment for most patients with type 1 and many...
