TDI is a more accurate and powerful method than PW or M-mode in determination of early cardiac involvement related to type 1 DM even in the subclinical phase as well as hereditary cardiomyopathies.

Intra-individual biological variation contributes to the variation in serial results and should therefore be included in the criteria for serum tumour marker assessment.

Tip 1 diyabetes mellituslu hastalarda karotis intima-media kalınlığı ve komplikasyonlarla ilişkisi ABS TRACT Objective: Atherosclerosis is the major cause of the morbidity and mortality in type 1 diabetes mellitus (DM). Carotid intima-media thickness (CIMT) is the early sign of atherosclerosis and thereby, also the sign of macrovascular diseases. In this study, we aimed to evaluate the CIMT in patients with type 1 DM, and its association with diabetic microvascular complications (nephropathy-retinopathy). Methods: One hundred and thirteen consecutive patients with type 1 DM without macrovascular disease were enrolled into this cross-sectional study. Age, gender, and body mass index matched 59 healthy subjects, were taken as the control group. Microvascular complications in diabetic patients were scanned. Ultrasonographic analysis of the carotid artery was performed with a high-resolution ultrasound scanner. Student's t, Mann Whitney U, Chi-square and Kruskal-Wallis tests, as well as multiple linear regression analysis were used for the statistical analysis. Results: Patients with type 1 DM had significantly higher CIMT compared to control group (p<0001). The CIMT of the patients with microvascular complications (nephropathy and/or retinopathy) was significantly increased (0.70±0.11 mm) compared with the patients without complications (0.63 ± 0.09 mm) (p=0.001). The increase in CIMT in type 1 DM in multiple regression analysis was dependent on the presence of proliferative retinopathy (beta=0.037, 95%CI 0.010-0.065, p=0.008), macroalbuminuria (beta=0.043, 95%CI 0.019-0.068, p=0.001), increased urinary albumin excretion (beta=0.00003, 95%CI 0.00001-0.00005, p=0.005) and duration of diabetes (beta=0.002, 95%CI 0.001-0.003, p=0.009). Conclusions: Increment of CIMT in type 1 diabetic patients was associated with microvascular complications, suggesting that diabetic microangiopathy is related with macroangiopathy. Therefore, there is a need for prospective studies to show the effect of increased CIMT on prognosis of type 1 DM.

AbstractThe aim of the study was to determine the frequency and titers of anti-thyroid peroxidase (Anti-TPO), anti-thyroglobulin (Anti-TG), and anti-glutamic acid decarboxylase (Anti-GAD) antibodies in Turkish patients with type 1 diabetes mellitus (DM), and to compare the frequency of anti-TPO and anti-TG titers in the presence or absence of anti-GAD. A total of 104 patients including 56 males and 48 females with type 1 DM and their age-, gender-, and body mass index-matched control group, including 31 males and 27 females, 58 cases in total with an age range of 15-50 years, were recruited into this study. In patients with type 1 DM, positive anti-GAD was detected in 30.8% (n=32). In patients with positive anti-GAD, rate of positive anti-TPO was 37.5%; however, in patients with negative anti-GAD, the rate of positive anti-TPO was 9.7% and the difference was statistically significant (p=0.001). In patients with positive anti-GAD, the rate of positive anti-TG was 18.8%. In patients with negative anti-GAD, the rate of positive anti-TG was 2.8%, and the difference between them was statistically significant (p=0.005). In patients with positive and negative anti-GAD, rates of both positive anti-TPO and anti-TG were 15.6% and 1.4%, respectively, with the difference showing statistical significance (p=0.004). Thyroid autoimmunity in type 1 DM patients with positive anti-GAD was apparently higher; therefore, these patients should be followed more frequently and carefully.
