Primary aldosteronism (PA) is the most common cause of secondary hypertension. Although decline in renal function especially that experienced after adrenalectomy (ADX) has been demonstrated, details of the mechanism remain to be elucidated. Aim of the study was to investigate the factors predicting renal outcome after ADX in PA. Twenty patients with PA and four patients with non-functioning adrenal tumor (NFT) as control were studied. eGFR, serum potassium, plasma aldosterone ...

The renin–angiotensin system is known to enhance erythropoiesis. (Pro)renin receptor ((P)RR), a specific receptor for renin and prorenin, has recently been identified. We have recently shown expression of (P)RR in a human erythroid cell line, YN-1. It is known that triiodothyronine (T3) and angiotensin-II (A-II) stimulate proliferation of erythroid cells. The aim of the present study is to clarify effects of T3 and A-II on expression of (P)RR in the ...

Aim: To clarify what arises from the decease of visceral adiposity in Japanese diabetic patients with visceral fat accumulation.Patients: Diabetic patients (n=30) whose visceral fat areas (V), determined with abdominal CT, were larger than 100 cm2.Methods: V was followed at every 6 month, and clinical profiles and course were compared of eight patients (group D), whose changes of V(ΔV=(<i...

Aims: To compare the pharmacokinetic and pharmacodynamic profiles of insulin aspart, biphasic insulin aspart 70 (BIAsp70), biphasic insulin aspart 50 (BIAsp50) and soluble human insulin under experimental conditions.Methods: In this randomised, four-period crossover study, 19 type 1 diabetic patients received subcutaneous injections of identical doses (0.2 U/kg) of either insulin aspart, BIAsp70, or BIAsp50 immediately before a standardized meal, or huma...

Purpose: Disorders of sex development (DSD) are defined as having, ‘A chromosome, germinal gland, or anatomical structure that is atypical in the native state’. There are two types of patients with DSD who consult a gynecologist: patients diagnosed in childhood (group A), and patients diagnosed based on unusual secondary sex characteristics in adolescence (group B). In group A, gynecologists are required as a member of a multidisciplinary medical team for DSD. On the...

Androgen is an important factor for determining body composition in males. Abdominal obesity is inversely correlated with serum androgen levels in men. Androgen receptor (AR) null male mice revealed late-onset visceral obesity, accompanying energy balance abnormality. We previously reported a novel synthetic steroid, S42 as a promising candidate of a selective androgen receptor modulator (SARM). When orchiectomized Sprague-Dawley rats were administered with S42 for 3 weeks, th...

Background: Nicotinamide phosphoribosyltransferase (NAMPT)/PBEF/visfatin is a widely expressed cytokine with various effects on glucose and lipid metabolism, cell survival, and inflammation. Despite a favorable body composition profile, acromegalic patients present insulin resistance, increased cardiovascular risk, and higher incidence of secondary tumors.Aim: Based on its relation to glucose and lipid metabolism and inflammation we hypothesized that NAM...

More than half of patients with multiple endocrine neoplasia type 1 (MEN1) develop gastroenteropancreatic neuroendocrine tumors (GEPNETs). Among GEPNETs in MEN1, insulinoma is the second common functioning tumor and often diagnosed by its pathognomonic clinical feature, i.e. hypoglycemia. Compared to other functioning and nonfunctioning GEPNETs in MEN1, insulinoma is known to develop in younger age. We have recently constructed a database of Japanese patients with MEN1 and her...

Background: Diabetes mellitus (DM) prevalence in patients with severe acute respiratory coronavirus virus (SARS-CoV-2) infection differs among studies, although pre-existing DM seems to double the risk of critical infection and mortality.Objectives: To evaluate incidence and mortality risk of SARS-CoV-2 infection in a large diabetic population in Northern Italy in pre-vaccine era.Methods: Retrospective, observational, big data stud...

Background & objectives: Vibration perception threshold (VPT) is the gold standard for diagnosis of diabetic peripheral neuropathy. The relationship between symptom severity and VPT remains to be determined. This study evaluated the diagnostic utility of symptoms using the NTSS-6 symptom score vis a vis Bio-thesiometry.Methods: diabetic patients with symptoms suggestive of peripheral neuropathy and 40 apparently healthy controls were studied. Detaile...
