Livadas Sarantis , Bothou Christina , Paparodis Rodis , Androulakis Ioannis , Angelopoulos Nicholas , Boniakos Anastasios , Anagnostis Panagiotis , Duntas Leonidas

Background: Levothyroxine (LT4-Rx) is one of the most prescribed drugs worldwide and the vast majority of patients receive long-term treatment. However, in a recent study of 291 subjects we found that 60% of this cohort were euthyroid two months after LT4-Rx discontinuation1.Aim of the study: A prospective clinical cohort follow-up study was carried out. In 688 subjects (82% females) aged 48.01±15.96 (range 17-84years) with 8.59±6.98...

Levothyroxine replacement therapy: once treatment is started, should it last indefinitely?

Livadas Sarantis , Bothou Christina , Androulakis Ioannis , Boniakos Anastasios , Angelopoulos Nicholas , Duntas Leonidas

Background: Levothyroxine (LT4) is one of the most prescribed drugs worldwide. Once started, about 90% of patients continue LT4 treatment long-term.Aim of the study: To evaluate the necessity of long-term thyroxine supplementation and to determine the prognostic factors that could identify which patients may discontinue LT4 treatment.Design and methods: LT4 replacement therapy was paused for at least six weeks in all patients conse...

Young lean women with evidence of both premature adrenarche and pubarche display a metabolic, hormonal and psychologic profile that is similar to that of their peers with polycystic ovary syndrome

Livadas Sarantis , Bothou Christina , Kanaka-Gantenbein Christina , Chiotis Dimitrios , Angelopoulos Nicholas , Macut Djuro , Chrousos George P.

Context: The early activation of adrenal zona reticularis, denoted by increased circulating levels of adrenal androgens before the age of eight years in girls is called premature adrenarche (PA), while the concomitant appearance of pubic hair is termed premature pubarche (PP). Girls with PA-PP display an unfavorable metabolic, hormonal and psychologic profile, compared to their normal peers and are also at an increased risk of developing polycystic ovary syndrome (PCO...

Introduction: Use of supplements (VDS) and vitamin-D measurements have been rising in the recent past globally. Despite increasing intake, our observations reveal that a large percentage of the population remains deficient (VDD). We designed the present real-world study, to address this controversy.Methods: We collected data from patients attending our clinics between March 2014 and December 2022. We recorded our subjects’ gender, age, history of VD...

Rising preoperative TPO titers decrease the risk for differentiated thyroid cancer in a linear fashion: a retrospective analysis of 1620 consecutive thyroid surgeries

Bantouna Dimitra , Zoupas Ioannis , C Jaume Juan , Imam Shanawaz , Livadas Sarantis , Angelopoulos Nicholas , Karvounis Evaggelos , Paparodis Rodis

Introduction: Chronic lymphocytic thyroiditis is an important risk factor for differentiated thyroid cancer (DTC) in surgical series, but the role of thyroid peroxidase antibodies (TPO) seems less clear in that regard. We designed the present study to evaluate that effect in our large patient population. Methods: We recruited subjects operated with total thyroidectomy in 4 sites (USA: 1, Greece: 3) during a period of 14 consecutive years. We gathered dat...

The role of preexisting diabetes mellitus on the risk for aggressive thyroid cancers

Paparodis Rodis , Bantouna Dimitra , Livadas Sarantis , Angelopoulos Nicholas , Androulakis Ioannis , Simeakis George , Zianni Dimitra , Perogamvros Ilias , Boniakos Anastasios , Rizoulis Andreas , Jaume Juan Carlos , Karvounis Evaggelos , Kapezanou Aikaterini , Askitis Dimitrios

Introduction: Multiple cancers have been described more commonly in patients with diabetes, and some exhibit increased aggressiveness of the tumor as well. This association has been debated with regard to thyroid cancer. With this work, we aim to clarify whether type 2 diabetes (DM2) or autoimmunity-related diabetes (type 1 diabetes+LADA=DM1) could coexist with thyroid cancers more aggressive as compared to those found in unaffected (non-DM) individuals....

Low TPO-antibody titers appear to promote aggressive thyroid cancers tumorigenesis: analysis of a large multinational dataset

Paparodis Rodis , Karvounis Evaggelos , Kapezanou Aikaterini , Bantouna Dimitra , Livadas Sarantis , Simeakis George , Askitis Dimitrios , Androulakis Ioannis , Angelopoulos Nicholas , Zianni Dimitra , Perogamvros Ilias , Boniakos Anastasios , Rizoulis Andreas , Imam Shanawaz , Carlos Jaume Juan

Introduction: In the thyroid gland, humoral immunity manifests with thyroid peroxidase (TPO) antibodies. In our studies, when TPO concentrations increased, thyroid cancers of follicular origin (TCFO) tended to develop less frequently.1 Other studies, though, reported an opposite trend in less aggressive cancers. The present work was designed to characterize the differential role of TPO antibodies in aggressive forms of TCFO (AGG) as compared to non-aggressive (NAG) ...
