Context:
The extent to which some pharmacological interventions reduce or increase the risk of biochemical conversion to type 2 diabetes mellitus (T2DM) in at-risk individuals is unclear.
Methods:
We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Scopus through 24 August 2017 for randomized controlled trials evaluating the effect of drugs suspected to modify the risk of biochemical conversion to T2DM.
Results:
We included 43 trials with 192,156 subjects (mean age, 60 years; 56% men; mean body mass index, 30.4 kg/m2). α-Glucosidase inhibitors, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, metformin, orlistat, phentermine/topiramate, and pioglitazone significantly reduced the risk of biochemical conversion to T2DM, whereas statins and nateglinide increased the risk. There was insufficient direct evidence regarding the effects of sulfonylureas, glucagon-like peptide-1 receptor agonists, dipeptidyl peptidase-4 inhibitors, and sodium-glucose cotransporter-2 inhibitors. Most trials were brief and evaluated this outcome during treatment without a withdrawal or washout period.
Conclusions:
Several drugs modify the risk of biochemical conversation to T2DM, although whether this effect is persistent and clinically relevant is unclear. Future studies need to focus on cardiovascular disease prevention, mortality, and patient-important outcomes instead of biochemical conversion to T2DM.
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.
