Assessment Of Erythrocyte Morphology In Patients With Type 2 Diabetes Mellitus: A Pilotstudy Of Electron Microscopy-Based Analysis In Relation To Healthy Controls, Tülay Mortaş, Şenay Arikan Durmaz, Şaban Cem Sezen, Yasemi̇n Savranlar
Turkish Journal of Medical Sciences
Background/aim: The present study aimed to assess erythrocyte morphology in newly diagnosed type 2 diabetes mellitus patients using scanning electron microscopy. Materials and methods: In total, 30 patients admitted to endocrine outpatient clinics were included in the study. The patients were divided into two groups according to their fasting blood glucose levels: type 2 diabetes mellitus (n = 15, fasting blood glucose levels ≥ 126 mg/dL) and control (n = 15, fasting blood glucose levels < 99 mg/dL). The patient's demographic characteristics, haemoglobin A1c levels, and scanning electron microscopy findings regarding erythrocyte morphology were recorded. Results: There was no significant difference between the control and type 2 diabetes mellitus group in terms of the participants' age (51.13 ± 8.53 vs. 50.33 ± 8.72 years, p = 0.8) and the male/female ratio (9/6 vs. 9/6). In the control group, discocytes were abundant, echinocytes were rare, and spherocytes were absent. On the other hand, discocytes were less common and echinocyte-shaped erythrocytes were more common in the type 2 diabetes mellitus group than in the control group. In addition, spherocytes were detected in the type 2 diabetes mellitus group. Moreover, the diameter of discocytes was significantly lower (p = 0.014), and blood glucose and haemoglobin A1c levels were significantly higher (p < 0.05 for both) in the type 2 diabetes mellitus group than in the control group. Conclusion: Our findings indicate that high glucose levels in type 2 diabetes mellitus patients lead to significant alterations in erythrocyte morphology, including decreased erythrocyte deformability and the formation of echinocytes and spherocytes due to eryptosis. The possibility of decreased erythrocyte deformability due to excessive eryptosis may disturb microcirculation in newly diagnosed, treatment-naïve type 2 diabetes mellitus patients who do not have any complications.

To evaluate the effects of diabetes on nitric oxide synthase (NOS) activity and on gene expressions of B-cell lymphoma protein 2 (Bcl-2) and caspase-3 in the renal tissues of streptozotocin (STZ)-induced rats. Materials and methods: Twenty rats were analyzed in 2 equally distributed groups of healthy controls and STZ-induced diabetic rats. Rats with blood glucose levels of >=250 mg/dL were considered diabetic. Renal tissue sections were analyzed histomorphologically and immunohistochemically. Gene expressions of caspase-3 and Bcl-2 were evaluated by real-time quantitative polymerase chain reaction. Results: Bcl-2 expression significantly decreased in the diabetic group, both at the gene and protein level. …

To determine the plasma prevalence and characteristics of diabetic retinopathy (DR) among Pakistani diabetic patients in the Faisalabad region. Diabetes mellitus (DM) is a major cause of avoidable blindness worldwide. People with DR are 25 times more likely to become blind than nondiabetics. Materials and methods: The incidence of retinopathy was determined in 1524 people with diabetes during April 2008 and January 2009. Physician-diagnosed diabetic patients underwent an eye examination by ophthalmoscopy and fundus photography. Participants were also interviewed and examined in order to determine demographic characteristics and medical history. Results: Of the 1524 patients screened, 183 (12%) had DR. …

Aims: It is known that there is a relationship between diabetic complications and chronic inflammation characterized by alterations in circulating acute phase proteins. It has been emphasized that inflammation contributes to diabetic complications and that gliclazide -an antidiabetic sulfonylurea - decreases the development of such complications. In this study, we aimed to investigate whether gliclazide or diet treatment has an effect on serum levels of acute phase reactants, markers of inflammation. Materials and Methods: Fifty-six newly diagnosed patients with type 2 diabetes and 30 clinically healthy subjects were evaluated prospectively. Twenty-six patients were treated with proper diet and daily gliclazide …
