ABSTRACT

OBJECTIVES: We aimed to investigate serum neudesin levels that has neural, metabolic functions in patients with polycystic ovary syndrome (PCOS). MATERIAL AND METHODS: The study included 180 women (age range, 18-44 years) with a diagnosis of PCOS and a control group that included 100 healthy females (age range, 18-46 years). Body mass index (BMI), waist circumference, Ferriman-Gallwey score, was evaluated and plasma glucose, lipid profile, estradiol, progesterone, total testosterone, prolactin, insulin, dehydroepiandrosterone sulfate (DHEA-S), FSH, LH, free T3, free T4, thyroid stymulating hormone (TSH), anti-thyroperoxidase (anti-TPO) antibody and neudesin levels were evaluated in all participants. RESULTS: BMI and waist circumference were similar between two groups. Ferriman-Gallwey score was significantly higher in the patient group. Fasting blood glucose, HbA1C, lipid parameters except triglyceride levels, free T3, free T4, TSH, anti-TPO were similar between the two groups. Triglyceride, insulin and HOMA values were significantly higher in PCOS patients. While follicle-stimulating hormone (FSH), estradiol, progesterone, prolactin and DHEAS levels were similar, LH was significantly higher in patients with PCOS. Serum neudesin level was significantly lower in PCOS patients with respect to controls (p = 0.015). Neudesin was positively correlated with insulin (r = 0.224, p = 0.037), and progesterone (r = 0.716, p = 0.001). Multiple regression analysis revealed that neudesin correlated with only progesterone (beta = 0.308, p = 0.001). CONCLUSIONS: Due to the association of decreased levels of neudesin with PCOS and correlation of neudesin with progesterone, neudesin may be related with one of patophysiologic pathways of PCOS. Still, it is not certain that decreased neudesin is involved in the pathogenesis of PCOS or is the result of the disorder.

ABSTRACT

OBJECTIVE: In this study, we aimed to evaluate serum irisin and apelin levels in patients with subclinical hypothyroidism (SCH) when they were subclinical hypothyroid and become euthyroid after levothyroxine therapy and association of these adipokines with markers of atherosclerosis such as serum homocysteine levels and carotid intima-media thickness (IMT). SUBJECTS AND METHODS: The study included 160 patients with newly diagnosed subclinical hypothyroidism due to Hashimoto's thyroiditis and 86 euthyroid healty subjects. Serum glucose and lipid profile, insulin, HOMA, TSH, free T3, free T4, anti-thyroperoxidase and anti-thyroglobulin antibodies, homocysteine, apelin and irisin levels were measured in all study subjects. Thyroid and carotid ultrasound examinations were performed. The subclinical hypothyroid group was reevaluated after 12-weeks of levothyroxine therapy when they became euthyroid. RESULTS: Clinical characteristics of the patient and control group were similar. Glucose, insulin and HOMA levels, lipid parameters and free T3 were similar between the two groups.. Serum homocystein was higher and apelin was lower in patients with SCH, but irisin levels were similar between the two groups. While thyroid volume was lower, carotid IMT was significantly greater in patients with SCH (pCarotidIMT:0,01). After 12-weeks of levothyroxine therapy, all the studied parameters remained unchanged except, serum freeT4, TSH, homocystein and apelin. While homocystein decreased (p: 0,001), apelin increased significantly (p = 0,049). In multivariate analysis, low apelin levels significantly contributed to carotid IMT (p = 0,041). CONCLUSIONS: Apelin-APJ system may play a role in vascular and cardiac dysfunction in patients with SCH and treatment of this condition may improve the risk of cardiovascular disease.

ABSTRACT

BACKGROUND: In order to apply the right treatment for hemostatic disorders in pediatric patients, laboratory data should be interpreted with age-appropriate reference ranges. OBJECTIVES: The purpose of this study was to determining age-dependent reference range values for prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen tests, and D-dimer tests. MATERIALS AND METHODS: A total of 320 volunteers were included in the study with the following ages: 1 month - 1 year (n = 52), 2 - 5 years (n = 50), 6 - 10 years (n = 48), 11 - 17 years (n = 38), and 18 - 65 years (n = 132). Each volunteer completed a survey to exclude hemostatic system disorder. Using a nonparametric method, the lower and upper limits, including 95% distribution and 90% confidence intervals, were calculated. RESULTS: No statistically significant differences were found between PT and aPTT values in the groups consisting of children. Thus, the reference ranges were separated into child and adult age groups. PT and aPTT values were significantly higher in the children than in the adults. Fibrinogen values in the 6 - 10 age group and the adult age group were significantly higher than in the other groups. D-dimer levels were significantly lower in those aged 2 - 17; thus, a separate reference range was established. CONCLUSIONS: These results support other findings related to developmental hemostasis, confirming that adult and pediatric age groups should be evaluated using different reference ranges.
