Introduction: The endocrine system is often affected in the course of HIV infection. However, hypopituitarism and diabetes insipidus are uncommon disorders in these patients and have been related to drugs, infections of the central nervous system and neoplastic infiltration, in extremely rare cases.Case report: We present a case of a 42-year-old man with HIV infection known since 2005, but undergoing antiretroviral therapy only since 2010 (emtricitabine/...

Background: TSH seems to be positively related to the degree of obesity and weight loss seems to induce a reduction in the TSH levels and T3Total. TSH is the first regulatory mechanism of total energy expenditure and T3 regulates energy metabolism and thermogenesis (1)Objective: The aim of this study was to investigate the association between thyroid function and body mass index (BMI) in obese population. And evaluate the influence of weight reduction af...

Introduction: The renin-angiotensin system (RAS) become upregulated very early on in pregnancy and is crucial in maintaining blood pressure. In addition to the peripheral RAS there is a uteroplacental RAS, which is also important in regulating placental function and development. Recent work has shown extra-renal sodium storage in the skin; it is suggested that the placenta may also function as a salt sensing organ and is important in regulating maternal blood pressure.<p c...

Both metabolism and cardiac function fluctuate over the course of the day according to energy supply and demand. The triiodothyronine (T3) regulates several genes related to metabolism and function in cardiomyocytes. Our previous data have suggested that there is a potential interrelationship between the regulation of cardiac function by T3 and the intrinsic circadian clock in the heart. Considering that: i) the hypothyroidism is associated to a reduction...

Introduction: The incidence of glucose metabolism alterations during the follow-up of surgically treated insulinomas is largely unknown. Our aim was to evaluate the incidence, and the clinical characteristics, of diabetes and prediabetes in this population.Methods: We retrospectively analyzed the cases diagnosed as insulinomas in a Central Hospital in Portugal in the period between January 1980 and December 2015.Results: We identif...

Objective: To assess clinical outcome after pituitary surgery in patients nonfunctioning pituitary adenomas (NFPA) surgically treated in the past 3 decades in three tertiary referral hospitals.Methods: A multicenter retrospective study on clinical and pathological characteristics, treatment patterns, and outcome in patients with NFPA periodically followed up in specialized neuroendocrinology units who underwent surgery in the period 1982–2015 was pe...

Introduction: Adult nesidioblastosis is a rare entity that has motivated the publication of several case reports, but long-term outcomes are rarely described. Distal or sub-total pancreatectomy is indicated in cases of severe symptoms or lack of response to medical treatment. We report the case of a patient with persistent nesidioblastosis after pancreatectomy keeping under medical treatment for 24 years.Clinical case: Woman currently with 81-years old, ...

Introduction: Insulinomas are pancreatic endocrine tumors originating in the beta cells, characterized by hypoglycemia resulting from insulin hypersecretion.Objectives: To characterize the demography, the clinical features, imagiological findings and pathological evaluation of the cases of insulinomas identified in the previous 35 years at São João Hospital.Methods: We retrospectively analyzed the cases diagnosed as insul...

The anterior pituitary gland occupies a central position in the hypothalamus–pituitary glands axes and secretes hormones involved in reproduction, growth, and metabolism. The plasma concentrations of pituitary hormones present fluctuations during the 24 h and are markedly altered during the hypothyroidism. The presence of an intra-pituitary circadian oscillator might be related to these oscillations; however, the molecular mechanism and the consequences of the hypothyroid...

Introduction: HIV infection and combined antiretroviral therapy (cART) have been associated with lipodistrophy and changes in body composition. However, there are few studies on body composition evolution of HIV-infected patients, under cART.Aims: To evaluate the evolution of body composition in HIV-1 infected patients under cART over 5 years.Methods: Retrospective, observational study in a cohort of HIV-infected patients on cART. ...
