Wnt signaling through low-density lipoprotein receptor-related protein 5 (LRP5) is an important determinant of bone mass regulation. Polymorphisms in the LRP5 gene have been associated with either osteoporotic phenotypes or normal bone mineral density (BMD) variation.Objective: To explore the influence of two LRP5 single nucleotide polymorphisms (SNPs) A1330V and V667M on BMD and serum levels of osteoprotegerin (OPG), receptor activator of nuclear factor...

Introduction and aims: Diabetic neuropathy may trigger the development of anemia in patients even before the onset of advanced renal failure. Autonomic neuropathy with subsequent renal denervation, combined with damaged erythropoetin producing fibroblasts in renal cortex, may have contributed to the early development of anemia in the patients with diabetes. Proliferative retonopathy, autonomic neuropathy, microalbuminuria, and moderate renal failure, suggesting that, factors o...

Background of study: Twin studies have shown that age at menarche may be subject to hereditary influences but the specific determinants are unknown. Estrogens are known to have an important role in menarche. Since aromatase is responsible enzyme for the conversion of androgens to estrogens, the aromatase (CYP19) gene could be a candidate gene for the regulation of menarche. The aim of this study was to investigate the possible association of the CYP19(TTTA)n poly...

Background of study: Experimental research supports the hypothesis that fetal exposure to androgen excess may programme in utero the development of PCOS in adult life. Potential mechanisms for prenatal androgenization could be a reduced binding capacity of androgens by SHBG or reduced aromatization of androgens by aromatase. The aim of this study was to examine whether the SHBG(TAAAA)n polymorphism, known to be associated with SHBG levels and the CYP19(TTTA)n<...

Objective: Androgen may be detrimental in the development of coronary artery disease (CAD) in women. We investigated possible associations between the (TAAAA)n polymorphism of sex hormone binding globulin (SHBG) gene promoter, which influences transcriptional efficiency of the SHBG gene and the severity of CAD in women.Methods: One hundred and twenty women (37–82 yrs), undergoing coronary angiography. CAD severity, history of angina, myocardial infa...

Introduction: The vascular protective effects of estrogens are known to be mediated by their binding to specific estrogen receptors (ER). However, the significance of genetic variations of the ER in vascular diseases has not been reported. We have examined the association between stroke and PvuII and XbaI polymorphisms of the estrogen receptor-alpha gene in patients with metabolic syndrome.Methods and subjects: The study population consisted by 84 male a...

Impaired estrogen (E2) action is important for cardiovascular disease (CAD) in both men and women. Associations of CAD with estrogen receptor polymorphisms, which may influence sensitivity to E2 have been reported for men but have not been confirmed for women. The aim of the present study was to investigate the association of estrogen receptor common polymorphisms with the severity of coronary disease in women undergoing coronary angiography.Estrogen rec...

Thyroid cancer in patients with hyperthyroidism is considered to be a rare event and its course seems to be more aggressive in patients with Graves’ disease. The coexistence of medullary thyroid cancer and hyperthyroidism is very rare and there are only 14 cases reported in the literature.The aim of this retrospective study is to assess the clinical and histological characteristics and the evolution of thyroid cancer in patients with different types...

Ectopic thyroid tissue, defined as thyroid tissue not located anterolaterally to the second and fourth tracheal cartages, is rare. In the majority of the cases it is located in the midline, between the foramen caecum and the proper location of the thyroid gland and most often it is found in the base of the tongue. We present a case of ectopic thyroid in the lower cervical area in a patient with a multinodular goiter. A 27-yr-old asymptomatic woman presented with a recent histo...

Background: With the increasing use of cancer immunotherapies in advanced solid organ and hematologic malignancies, endocrinologists are beckoned to manage endocrine complications with unique presentations and natural history in the already challenged oncology patient. We describe four patients illustrating the multifarious endocrine adversities of checkpoint inhibitors.Cases: Patient 1 is a 35-year old male with refractory Hodgkin’s lymphoma, previ...
