    Evaluation of arterial stiffness and serum endocan levels in patients with primary aldosteronism with new-onset hypertension and long-term hypertension
    (Springer, 2023) Can, M.; Kocabas, M.; Burgucu, H. C.; Yarar, Z.; Karadeniz, Y.; Karakose, M.; Yerlikaya, F. H.
    Purpose There is growing evidence that prolonged exposure to high serum aldosterone concentrations results in target organ damage to the heart, kidney, and arterial wall, and that primary aldosteronism (PA) is associated with increased cardiovascular risk. In this study, we aimed to evaluate cardiovascular disease (CVD) risk indicators such as arterial stiffness [with pulse wave velocity (PWV) measurement] in PA patients and endocan levels, which is a biomarker of endothelial dysfunction. Methods 28 patients with PA were included in our study. As the control group, 14 patients with essential hypertension (EHT) and 28 normotensive healthy volunteers were included. Height, weight, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), serum fasting glucose, insulin, hemoglobin A1c (HbA1c), C-reactive protein (CRP), lipids and endocan levels of all subjects in the PA, EHT and control groups were measured. PWV measurements were performed to assess arterial stiffness. Results In the PA group, PWV levels were similar to the EHT group, and endocan levels were lower than the EHT group. In the PA group, PWV levels were higher than the control group, and endocan levels were lower than the control group. When we compared the PA group with new-onset HT with the PA group with long-term HT, PWV levels were higher in the PA group with long-term HT. When we compared the long-term HT group with the EHT group, PWV levels were higher in the long-term HT PA group and endocan levels were higher in the EHT group. When we compared the PA group with long-term HT with the control group, PWV levels were higher in the PA group with long-term HT, and endocan levels were similar in both groups. Conclusions In our study, it was determined that arterial stiffness increased in PA cases with long-term HT compared to PA cases with new-onset HT, EHT cases and normotensive healthy cases. We found that endocan levels in PA patients were also lower than both EHT patients and healthy controls.

    NEW BIOMARKERS TO PREDICT CARDIOVASCULAR RISK IN PATIENTS WITH ADRENAL INCIDENTALOMA; IRISIN AND NESFATIN-1
    (Editura Acad Romane, 2022) Can, M.; Kocabas, M.; Karakose, M.; Alsancak, Y.; Yerlikaya, F. H.; Burgucu, H. Caliskan; Cordan, I
    Objective. In our study, we aimed to investigate the levels of irisin, nesfatin-1 and the relationship between levels of these relatively new molecules with cardiometabolic risk markers; carotid intima-media thickness (CIMT), epicardial adipose tissue (EAT) thickness in patients with nonfunctional adrenal incidentaloma (NFAI). Materials and Methods. Patients with NFAI (n=59) and age, sex and body mass index-matched healthy control subjects (n=59) were enrolled in this study. Serum glucose, insulin, C-reactive protein (CRP), lipid, irisin and nesfatin-1 levels and echocardiographic CIMT and EAT thickness measurements were performed in patients and controls. Results. The irisin level was 17.58 +/- 4.38 pg/mL in the NFAI group, significantly higher (p<0.001) than 14.03 +/- 4.03 pg/mL in the control group. Nesfatin-1 level was significantly lower in the NFAI group 194.98 +/- 119.15 pg/mL ((p < 0.001)) versus 303.48 +/- 200.78 pg/mL in the control group. A positive correlation was found between irisin and nesfatin-1 levels and CIMT and EAT thickness in the NFAI group. Conclusions. In our study, we found that irisin level was higher and nesfatin-1 level was lower in patients with NFAI, and both irisin and nesfatin-1 levels were associated with CIMT and EAT thickness in NFAI patients.

    THYROID DISORDERS PREVALENCE IN A COHORT OF KIDNEY TRANSPLANT RECIPIENTS
    (Editura Acad Romane, 2020) Karakose, S.; Cordan, I; Gonulalan, G.; Karakose, M.; Kurtgorz, P. O.; Baloglu, I; Turkmen, K.
    Context. As the life expectancy prolongs, malignancy has become an important issue in renal transplant recipients (RTRs). Thyroid cancer is the most common endocrine malignancy with ongoing increase in incidence all over the world. Objective and design. This is a cross-sectional study that investigates the thyroid disorders and the prevalence of thyroid nodule and cancer in RTRs. Subjects and methods. 204 RTRs were evaluated for the thyroid diseases with ultrasonography, serum thyroid stimulating hormone, free T4, free T3 levels, antithyroglobulin antibody and anti-thyroid peroxidase antibody levels; FNAB was carried if required. Results. 191 patients (94.1%) had normal thyroid function. Subclinical hypothyroidism was diagnosed in 11 patients, subclinical hyperthyroidism in 1 patient and low T3 syndrome in 4 patients. The FNAB was performed in 17 (27.9%) from 61 patients with thyroid nodule. The cytological examination of biopsy materials revealed that 2 (11.8%) nodules were suspicious for malignancy, 13 (76.5%) were benign, and 2 (11.8%) with non diagnostic cytology. Thyroid cancer prevalence was 0.2% in Turkey but we detected that 0.98% of RTRs had thyroid cancer. Conclusions. Screening the RTRs for thyroid disorders is necessary, so that early diagnosis and appropriate treatment of thyroid disease and cancer may improve the quality of life.
