    Sagittal Abdominal Diameter as an Anthropometric Measure of Cardiovascular and Graft Loss Risk in Renal Transplant Recipients
    (2015) Bal, Z.; Uyar, M. E.; Tutal, E.; Guliyev, O.; Colak, T.; Sezer, S.; Haberal, M.; 0000-0002-3462-7632; 0000-0002-8372-7840; 26036544; IAO-2608-2023; AAJ-8097-2021; AAZ-5795-2021; AAJ-8554-2021
    Background. Sagittal abdominal diameter (SAD) has been presented as a stronger prognostic factor for all-cause and cardiovascular mortality in the general population. The aim of this study was to evaluate the relationship between SAD and its associated parameters in renal transplant recipients. Methods. One hundred eighty-one renal transplant recipients were enrolled in the study. All patients were evaluated according to standard clinical and biochemical parameters. Anthropometric measurements were performed for all patients. Pulse-wave velocity (PWV) was determined from pressure tracing over carotid and femoral arteries with the use of the Sphygmocor system. Results. Patients were divided into 2 groups according to SAD measurements. Group 1 (n = 127) was defined as SAD <24.3 cm, and group 2 (n = 54) was defined as SAD > 24.3 cm. Patients in group 2 had significantly higher triglycerides, C-reactive protein (CRP), uric acid, systolic blood pressure, PWV, and body mass index measurements compared with group 1 (P < .05 for all). In group 2, estimated glomerular filtration rate (eGFR) was significantly lower than group 1 (P = .022). SAD had positive correlation with PWV, systolic and diastolic blood pressure, body mass index, triglycerides, fasting glucose, CRP, and uric acid (P < .05 for all). On stepwise linear regression analyses, proteinuria (P = .005), SAD (P = .001), and CRP (P = .015) independently predicted the degree of percentage change of eGFR. Conclusions. Considering the significant association of visceral fat with inflammation and cardiovascular disease, estimating visceral fat by means of SAD could be a useful tool to stratify cardiovascular risk as well as graft function in renal transplant recipients.

    New-Onset Diabetes and Glucose Regulation Are Significant Determinants of Left Ventricular Hypertrophy in Renal Transplant Recipients
    (2015) Sezer, Siren; Uyar, Mehtap Erkmen; Tutal, Emre; Bal, Zeynep; Guliyev, Orhan; Colak, Turan; Hasdemir, Efe; Haberal, Mehmet; 25945353
    Background. New-onset diabetes after transplantation (NODAT) is associated with decreased graft survival and an increased risk for cardiovascular disease. The objective of this study was to evaluate the risk factors for development of NODAT and its' relationship with arterial stiffness and left ventricular mass index (LVMI) in kidney transplant recipients. Methods. 159 kidney transplant recipients were selected from our transplantation center who underwent renal transplantation between years 2007 and 2010. Results. Among 159 patients, 57 (32.2%) patients were with NODAT who were significantly older than patients without diabetes (P: 0.0001). Patients with NODAT had significantly higher pulse wave velocity (PWv) (P: 0.033) and left ventricular mass index LVMI (P: 0.001) compared to patients without NODAT. Further analysis was done according to LVMI as follows: LVMI > 130 g/m(2) (n: 57) and LVMI <= 130 g/m(2) (n: 102). We observed higher office systolic and diastolic BP, serum trygliceride, glucose, creatinine, age, and HbA1c (P: 0.0001) levels in patients with LVMI > 130 g/m(2). Linear regression analysis revealed that HbA1c was the major determinant of LVMI (P: 0.026, beta: 0.361). Conclusions. HbA1c is the major determinant of LVMI, so strict control of serum glucose levels is essential for preventing cardiovascular disease in patients with NODAT.
