Insights

Sodium-glucose cotransporter-2 (SGLT2) inhibitors significantly reduced end-stage renal disease risk in type 2 diabetes patients with advanced chronic kidney disease (CKD5). SGLT2 inhibitors did not increase risks for major adverse cardiovascular events or mortality in this population.

Area of Science:

  • Nephrology
  • Endocrinology
  • Pharmacology

Background:

  • Sodium-glucose cotransporter-2 (SGLT2) inhibitors are recognized for their benefits in diabetes and chronic kidney disease (CKD).
  • The specific impact of SGLT2 inhibitors on patients with type 2 diabetes (T2DM) and advanced CKD (CKD stage 5) requires further investigation.

Purpose of the Study:

  • To evaluate the efficacy and safety of SGLT2 inhibitors in T2DM patients diagnosed with CKD stage 5.
  • To assess the effect of SGLT2 inhibitors on the risk of end-stage renal disease (ESRD) and other adverse outcomes.

Main Methods:

  • An observational cohort study utilizing Taiwan's National Health Insurance Research Database (NHIRD).
  • T2DM patients newly identified with CKD5 were propensity score matched (1:4) into SGLT2 inhibitor users and non-users.
  • Outcomes including new-onset ESRD, major adverse cardiovascular events (MACCEs), infection-related hospitalizations, and mortality were compared.

Main Results:

  • SGLT2 inhibitor use was associated with a significantly lower risk of new-onset ESRD (HR 0.59, 95% CI: 0.59-0.74).
  • No significant differences were found in the risks of MACCEs, infection-related hospitalizations, infection-associated mortality, or all-cause mortality between the groups.

Conclusions:

  • SGLT2 inhibitors demonstrate renal protective effects in T2DM patients with CKD stage 5.
  • SGLT2 inhibitors appear safe for use in this population, without an increased risk of cardiovascular events or infections.

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...

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...

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...

Oral Hypoglycemic Agents: Sulfonylureas

Sulfonylureas are oral hypoglycemic agents utilized in treating type 2 diabetes. They are characterized by their unique sulfonylurea chemical structure. The family of sulfonylureas is divided into generations. First-generation sulfonylureas, including tolbutamide (Orinase), chlorpropamide (Diabinese), and tolazamide (Tolinase), trigger insulin release from pancreatic β cells and enhance peripheral tissues' insulin sensitivity. The second-generation members, such as glipizide...

Renal Failure: Dose Adjustments

In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors01:19

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are...
