The Effects of Blood Glucose Regulation and Treatment Regime on Mean Platelet Volume in Type 2 Diabetic Patients
(Wolters Kluwer Medknow Publications, 2021) Alay, M.; Atmaca, M.; Ucler, R.; Aslan, M.; Seven, I; Dirik, Y.; Sonmez, M. G.
Background: Mean platelet volume (MPV) is associated with cardiovascular morbidity and mortality in type 2 diabetic patients. However, the effects of blood glucose regulation and treatment regime on MPV has not been adequately studied in type 2 diabetic patients. Aims: We studied the effects of blood glucose regulation and treatment regimen on mean platelet volume in Type 2 diabetic patients. Subjects and Methods: A total of 232 diabetic patients who were admitted to the hospital in short intervals of 3 months in the last 2 years were included in the study. When the second admission HbA(1c) was greater than the first admission HbA(1c), they were classified as being in the deteriorated blood glucose regulation group, otherwise they were classified in the improved blood glucose regulation group. Also, the deteriorated and improved blood glucose regulation groups were classified based on therapy modalities as the sulfonylurea + metformin group and the insulin + metformin group. Paired t-test was used for comparison of the groups. Results: Of the 232 patients, 98 (42.2%) were male and 134 (57.8%) were female. There were 126 (55.2%) patients using sulfonylurea + metformin, while 106 (44.8%) patients were using insulin + metformin. MPV levels were significantly increased in patients with deteriorating glucose regulation (p = 0.003). This increase in MPV was only seen in the oral hypoglycemic treatment group (p = 0.003). Conclusions: Our results suggested a close relationship between poor glycemic control and increased platelet activity in type 2 diabetic patients with oral antidiabetic therapy when compared to the insulin and metformin therapy modality.
Evaluation of Blood Neutrophil To Lymphocyte and Platelet To Lymphocyte Ratios According To Plasma Glucose Status and Serum Insulin-Like Growth Factor 1 Levels in Patients With Acromegaly

Introduction: Cardiovascular, respiratory, and cerebrovascular diseases and malignancies are responsible for morbidity and mortality in acromegaly. Also these diseases are associated with chronic inflammation. The neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are currently gaining interest as new markers of inflammation. Moreover, increased morbidity and mortality are positively correlated with the presence of diabetes and levels of insulin-like growth factor 1 (IGF-1) in acromegaly. The objective of the present study was to investigate the relationship between these markers and acromegaly according to plasma glucose status and serum IGF-1 levels. Materials and Methods: We retrospectively analyzed data from 61 acromegaly patients who were in a newly diagnosed period (35 male, 26 female; mean age 38.13 +/- 13.98). Patients with normal plasma glucose (n = 27), impaired fasting glucose (n = 18), and diabetes mellitus (n = 16) were categorized into three different groups. NLR and PLR were compared between the study groups and were evaluated according to IGF-1 levels. Results: There were no statistically significant differences inNLR and PLR measurements among the study groups (p > 0.05). However, there were significant positive correlations between NLR and IGF-1 levels and between PLR and IGF-1 levels when all patients were evaluated (r = 0.334, p = 0.011 and r = 0.277, p = 0.035, respectively). Conclusions: This is the first report studying the relationship of NLR and PLR with glucose status and IGF-1 levels in acromegaly patients. Our study results suggest that subclinical inflammation may play a role in increased incidence of mortality and morbidity, which depends on uncontrolled IGF-1 levels in patients with acromegaly.
The Relationship Between 25 Hydroxy Vitamin D3 and Thyroid Antibodies With Thyroid Benign-Malign Neoplasms
(Wolters Kluwer Medknow Publications, 2019) Yildiz, S.; Ekinci, O.; Ucler, R.
Objective: To study the relationship between vitamin D and thyroid antibodies with thyroid benign-malign neoplasms. Materials and Methods: The vitamin D vitamin and thyroid antibodies of 179 patients who underwent thyroidectomy for thyroid nodule were retrospectively reviewed. Results: The mean age of the patients was 44.97 +/- 14.139. Vitamin D levels were 14.473 +/- 4.9999 ng/ml in women and 19.584 +/- 6.1981 ng/ml in men and the mean was 15.016 +/- 5.3579 ng/ml. There was a significant relationship between sex and vitamin D level (P < 0, 05). Antithyroglobulin antibody (anti-TGB) had been detected in 95 patients and Antithyroid peroxidase antibody (anti TPO) in 58 patients. There was no significant relationship between vitamin D levels (P: 0, 65), anti-TPO positivity (P: 0, 86), and anti-TGB (P: 0, 12) with benign-malignant neoplasm of thyroid. There was no relationship between vitamin D and metastatic disease (P: 0, 30) as well. In addition, no association was found between malignancy and metastasis (P = 0.068, P = 0.14, P: 0, P = 0, respectively) with thyroid antibody positivity (anti TPO and/or anti TGB) in severe deficiency (<10 ng/ml) and deficiency (< 20 ng/ml) of vitamin D. Conclusion: Vitamin D deficiency or thyroid autoantibodies did not have any significant effect on thyroid malignancies or metastatic disease separately or together.
