A 78-year-old woman presented herself at emergency for the appearance of severe dyspnea. An electrocardiogram showed signs of inferior and anterior necrosis, and laboratory tests showed a small increase of myocardial cytonecrosis enzymes. An echocardiogram detected a reduction of global systolic function (ejection fraction [EF] approximately 40%) as well as akinesia of the apex, interventricular septum middle segments, and anterior and anterolateral walls, with basal segments showing compensatory hyperkinesia. The coronarography showed a coronary tree substantially free from significant lesions. The patient was transferred to the cardiology unit of our hospital. Based on the contained increase of the cardiac enzymes, the absence of coronary lesions, and the presence of typical echocardiography alterations, we suspected a Tako-tsubo-like syndrome. On deeper anamnestic investigation, an event of strong emotional stress emerged preceding the hospital admission that confirmed the pathology, even though it is atypical to see clinical presentation a long time after a stressful event.

  Objective  The key goal of diabetes management is to prevent complications. While the patho-physiological mechanisms responsible for diabetes complications have been extensively studied, at present it is impossible to predict which patient with diabetes could develop complications. In recent years, the role of leukocyte telomere length in the pathogenesis of cardiovascular disease and Type 2 diabetes has been investigated. However, studies aiming to investigate the role of telomeres in the development and progression of Type 2 diabetes, as well as diabetic complications, are still lacking. As a consequence, this study aimed to verify whether leukocyte telomere length is associated with the presence and the number of diabetic complications in a sample of patients with Type 2 diabetes.

Methods  This is a cross-sectional study. Nine hundred and one subjects were enrolled, including 501 patients with Type 2 diabetes, of whom 284 had at least one complication and 217 were without complications, and 400 control subjects. Leukocyte telomere length was measured by quantitative real-time PCR.

Results  Patients with diabetes complications had significantly shorter leukocyte telomere length than both patients without diabetes complications and healthy control subjects. Moreover, among patients with diabetes complications, leukocyte telomere length became significantly and gradually shorter with the increasing number of diabetes complications. The magnitude of the effect of the decrease of the abundance of telomeric template vs. a single-copy gene length (T/S ratio) on complications is described by the estimated odds ratio OR = 5.44 (95% CI 3.52-8.42).

Conclusions  The results of the study support the hypothesis that telomere attrition may be a marker associated with the presence and the number of diabetic complications.
