Primary Care-Based Investigation of the Effect of Sitagliptin on Blood Pressure in Hypertensive Patients With Type 2 Diabetes
Bibliographic record
Abstract
BACKGROUND: The influence of long-term sitagliptin therapy on office blood pressure (BP) and home BP has been unclear. METHODS: In a retrospective cohort study of 454 patients with type 2 diabetes, the following variables were analyzed before and at 3, 6, 9, and 12 months after initiation of sitagliptin therapy: office systolic blood pressure (SBP), office diastolic blood pressure (DBP), office pulse rate, morning home SBP, morning home DBP, morning home pulse rate, evening home SBP, evening home DBP, evening home pulse rate, hemoglobin A1c (HbA1c), plasma glucose, lipid profile, and renal function parameters. RESULTS: The office SBP showed a significant decrease after 6 and 12 months of sitagliptin therapy (P < 0.01 and P < 0.01, respectively), while office DBP was decreased significantly at all time points of evaluation (3, 6, 9, and 12 months: P < 0.05, P < 0.001, P < 0.001, and P < 0.05, respectively). Analysis of covariance revealed a significant decrease in office SBP after 6 and 12 months, as well as significant reduction of office DBP after 6 and 9 months. Morning home SBP and DBP were significantly reduced after 6 months, as was evening home DBP after 6 and 12 months, but there was no significant decrease in evening home SBP. HbA1c and plasma glucose levels were significantly reduced at all time points of evaluation. Examination of the lipid profile revealed that total cholesterol, low-density lipoprotein cholesterol, and triglycerides were also decreased at all time points of evaluation, while high-density lipoprotein cholesterol was significantly reduced after 3, 9, and 12 months. Significant reduction of the estimated glomerular filtration rate was observed after 6, 9, and 12 months, and the urinary albumin/creatinine ratio was significantly lower at 9 and 12 months. Serum creatinine was increased significantly at all time points of evaluation. CONCLUSIONS: BP was slightly but significantly reduced from 6 months after initiation of sitagliptin therapy, indicating that this antidiabetic drug has pleiotropic effects, including an antihypertensive effect.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
