Serum Brain-Derived Neurotrophic Factor is Related to Platelet Reactivity and Metformin Treatment in Adult Patients With Type 2 Diabetes Mellitus
Abstract
OBJECTIVES: The aim of this study was to investigate the association of serum brain-derived neurotrophic factor (BDNF) levels with platelet reactivity and antidiabetes treatment, as well as serum adipocytokine concentrations.
METHODS: This observational, open-label study enrolled 149 patients. Serum BDNF, hematologic, biochemical parameters and platelet reactivity were measured. Blood samples were taken after the last acetylsalicylic acid dose.
RESULTS: Patients with high BDNF levels were younger (65.60±8.956 vs. 68.59±8.516) and smoked cigarettes more frequently (14.6% vs. 4.1%); they were more commonly being treated by metformin (77.3% vs. 54%); had higher platelet counts (245.81±68.85 103/mm3 vs. 206.61±44.48 103/mm3); had shorter collagen-adenosine diphosphate closure time (CADP-CT) values (104.88±69.73 s vs. 140.93±86.63 s); had higher triglyceride concentrations (140.73±67.5 vs. 121.76±60.49) and had higher concentrations of serum thromboxane B2 (0.938±1.59 vs. 0.364±0.76). In univariate linear regression analyses, predictive factors for serum BDNF levels above the median were metformin treatment, current smoking, platelet count, triglyceride concentration, total cholesterol concentration and CADP-CT >74 s. In multivariate backward stepwise analysis CADP-CT >141 s; adiponectin concentration >4.22 µg/mL; total cholesterol and low-density lipoprotein levels were independently associated with serum BDNF levels above the median.
CONCLUSIONS: Our results suggest that BDNF…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 149 participants or records.
