Abstract

Insights

Certain medications can lower or raise the risk of developing type 2 diabetes mellitus (T2DM). Further research is needed to confirm if these effects are lasting and clinically significant for patients.

Area of Science:

  • Pharmacology
  • Endocrinology
  • Clinical Trials

Background:

  • The impact of pharmacological interventions on type 2 diabetes mellitus (T2DM) risk in susceptible individuals is not fully understood.
  • Clarifying drug effects on T2DM conversion is crucial for preventative strategies.

Purpose of the Study:

  • To systematically review randomized controlled trials (RCTs) assessing drug effects on biochemical conversion to T2DM.
  • To identify medications that may alter T2DM risk in at-risk populations.

Main Methods:

  • Comprehensive literature search of major databases (MEDLINE, Embase, Cochrane, Scopus) up to August 2017.
  • Inclusion of 43 RCTs involving 192,156 participants.
  • Analysis of drugs suspected to modify T2DM conversion risk.

Main Results:

  • Alpha-glucosidase inhibitors, ACE inhibitors, ARBs, metformin, orlistat, phentermine/topiramate, and pioglitazone significantly reduced T2DM risk.
  • Statins and nateglinide were associated with an increased risk of T2DM conversion.
  • Limited evidence exists for sulfonylureas, GLP-1 RAs, DPP-4 inhibitors, and SGLT-2 inhibitors; most trials lacked withdrawal periods.

Conclusions:

  • Several drug classes influence the risk of biochemical conversion to T2DM.
  • The persistence and clinical relevance of these drug-induced risk modifications require further investigation.
  • Future research should prioritize patient-important outcomes, mortality, and cardiovascular disease prevention over solely biochemical T2DM conversion.

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...

meta-Directing Deactivators: –NO2, –CN, –CHO, –⁠CO2R, –COR, –CO2H

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

Diabetes Mellitus: Overview and Type I Subtype

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Gene Conversion

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.
Percentiles are a type of fractile that partition data into...
