Turner syndrome results from the entire or partial loss of the second X chromosome, and is associated with a number of medical problems. Affected women require long-term medical follow-up. This study investigated the status of medical follow-up focusing on the transition for young adult women with Turner syndrome (TS). The clinical profiles of 63 women with TS over the age of 16 were retrospectively examined. Thirty-three women are continuously followed by pediatric endocrinologists at our pediatric division...

Type 2 diabetes, which is characterized by a combination of decreased insulin secretion and decreased insulin sensitivity, can be delayed or prevented by healthy lifestyle behaviors. Therefore, it is important that the population in general understands their personal risk at an early age to reduce their chances of ever developing the disease. A family history of hypertension is known to be associated with insulin resistance, but the effect of a family history of hypertension on the onset of type 2 diabetes has not well been examined...

Primary aldosteronism (PA) is caused by excess secretion of aldosterone and is an independent risk factor for cardio-cerebro-vascular (CCV) events. The goal of treatment of PA should include prevention of CCV events. A definitive diagnosis of PA is established by confirmatory tests [saline infusion test (SIT), furosemide upright test (FUT) and captopril challenge test (CCT)]. However, there is no information on whether the hormone levels measured by these confirmatory tests are associated with CCV events. The aim of this retrospective study was to elucidate the relationship between the results of the above confirmatory tests and prevalence of CCV disease in patients with PA...

Obesity can be associated with systemic low-grade inflammation that leads to obesity-related metabolic disorders. Recent studies raise the possibility that the inflammation in hypothalamus, liver and white adipose tissue (WAT) contributes to the pathogenesis of diet-induced obesity. We focus on the role of interleukin (IL)-10, an anti-inflammatory cytokine produced from spleen in obesity because it is indicated that obesity decreases the expression of pro-inflammatory cytokines in spleen. Obesity results in decrease of IL-10 synthesis from spleen, probably due to reduction of B-cells expression by promoting oxidative stress and apoptosis in spleen...

Prenatal undernutrition and postnatal overnutrition increase the risk of some peripheral and central metabolic disorders in adulthood. We speculated that disturbances of appetite/metabolic regulatory factors might already have been established in the early stages of life and contribute to obesity later in life. The effects of a high-fat diet on the levels of peripheral and central appetite/metabolic regulatory factors were compared between the offspring of normally nourished dams and those of undernourished dams in the peri-pubertal period...

We aim to explore effects of Ketotifen on metabolic profiles, inflammation and oxidative stress. Sprague Dawley (SD) male rats were randomly divided into normal control group (NC) and experimental groups, and experimental group rats were fed with high-sugar and fat diet for 6 weeks. Then, experimental group rats were divided into diabetes group (DM) and ketotifen treatment group (KT). KT group was given ketotifen via Intragastric for 8 weeks with the dosage of 0.09 mg/kg•d. Fasting plasma glucose (FPG) was measured using glucose oxidase-phenol amino phenazone method...

This study aimed to assess the relationship between the metabolic effect after laparoscopic sleeve gastrectomy (LSG) in morbidly obese Japanese patients, with or without type 2 diabetes mellitus (T2DM), and improved pancreatic steatosis (PS). The study enrolled 27 morbidly obese Japanese patients who were undergoing LSG. Their clinical and metabolic effects were evaluated at baseline and six months after LSG. Pancreas volume (PV), pancreatic attenuation (PA), and splenic attenuation (SA) were measured using a 64-row computed tomography (CT)...

Subclinical hypothyroidism (SCH) has a high global prevalence. Most SCH patients have mild cases (thyrotropin ≤10 mIU/L). Treatment recommendations for mild SCH are controversial, which raises concerns about the natural history of mild SCH. We aimed to clarify the natural history of mild SCH. This is a prospective population-based study. We measured thyroid function in 11,000 participants in the REACTION study and followed 505 newly diagnosed mild SCH patients aged 40-years or older between 2011 and 2014...

Asymmetric dimethylarginine (ADMA) is a nonselective nitric oxide (NO) synthase inhibitor associated with cardiovascular and metabolic disorders. NO regulates placental blood flow, which plays an important role in fetal growth. Many epidemiological studies have disclosed that restricted fetal growth is associated with an increased risk of insulin resistance in adult life. We studied the relationship between ADMA in cord blood and birth size. Nine small for gestational age (SGA) and 32 appropriate for gestational age (AGA) infants were studied...

Recent studies imply that euthyroid Hashimoto's thyroiditis (HT) might be related with impaired HRQoL, depression and anxiety. Ninety three patients with euthyroid HT and 31 age- and gender-matched euthyroid control subjects were enrolled into this study. SF-36 questionnaire, Beck Depression Inventory and Beck Anxiety Inventory tests were used for evaluating HRQoL, depression and anxiety. Beck Depression Inventory scores were higher in patients with HT compared to control subjects (7.5 (4.0-14.75) vs. 5.0 (2...

To date, several clinical trials have compared differences in glucose fluctuation observed with dipeptidyl peptidase-4 inhibitor treatment in patients with type 2 diabetes mellitus. However, most patients were assessed for limited periods or during hospitalization. The aim of the present study was to evaluate the effects of switching from sitagliptin to vildagliptin, or vice versa, on 12-week glucose fluctuations using self-monitoring of blood glucose in the standard care setting. We conducted a multicenter, prospective, open-label controlled trial in Japanese patients with type 2 diabetes...

We attempted to identify the predictors of an inadequate hypoglycemia in insulin tolerance test (ITT), defined as a blood glucose level higher than 2.8 mmol/L after insulin injection, in Japanese patients with suspected or proven hypopituitarism. A total of 78 patients who had undergone ITT were divided into adequate and inadequate hypoglycemia groups. The relationships between the subjects' clinical parameters and inadequate hypoglycemia in ITT were analyzed. Stepwise logistic regression analysis identified high systolic blood pressure (SBP) and high homeostasis model assessment of insulin resistance (HOMA-IR) as being independent factors associated with inadequate hypoglycemia in ITT...

Pancreatic islets express high levels of the orphan G-protein coupled receptor C5C (GPRC5C), the function of which remains to be established. Here we have examined the role of GPRC5C in the regulation of insulin secretion and β-cell survival and proliferation using human and mouse pancreatic islets. The expression of GPRC5C was analysed by RNA-sequencing, qPCR, western blotting and confocal microscopy. Insulin secretion and cell viability were determined by RIA and MTS assays, respectively. GPRC5C mRNA expression and protein level were reduced in the islets from type-2 diabetic donors...

Evidence has shown that endoplasmic reticulum (ER) stress was involved in the progression to type 2 diabetes mellitus (T2DM) and development of insulin resistance. Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a novel secreted protein upregulated by ER stress. This study aimed to assess serum level of MANF in normal glucose tolerance (NGT) participants and newly diagnosed prediabetic and T2DM patients. A total of 257 participants with NGT, newly diagnosed prediabetes or T2DM were recruited from Yinchao and Hangtian communities of Chengdu, Sichuan, China...

Gestational diabetes (GDM) and type 2 diabetes (T2DM) share part of pathomechanism and several T2DM susceptibility genes are demonstrated to be associated with GDM. No information on the genetics of GDM, however, was available in Japanese women. In this study, T2DM risk variants (45 single nucleotide polymorphisms [SNPs] from 36 genes) identified in previous studies were genotyped using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry in a cohort of 171 Japanese women with GDM and 128 normal glucose tolerance (NGT) diagnosed by the new International Association of Diabetes in Pregnancy Study Group criteria...

Ad4-binding protein/steroidogenic factor 1 (Ad4BP/SF-1), a member of the nuclear receptor superfamily, is expressed in steroidogenic cells and regulates all steroidogenic gene expression. We recently employed mRNA and chromatin immunoprecipitation sequence (ChIP-seq) to demonstrate that Ad4BP/SF-1 directly regulates the expression of nearly all glycolytic genes. The pentose phosphate pathway (PPP) contributes to the production of nicotinamide adenine dinucleotide phosphate (NADPH). Although the expression of PPP genes and intracellular NADPH were decreased by Ad4BP/SF-1 knockdown, these genes were not the direct targets of Ad4BP/SF-1...

Leptin and visfatin are implicated in breast cancer risk but studies accounting for bioavailability of leptin are sparse. Reports on the association of leptin gene (LEP) and leptin receptor gene (LEPR) polymorphisms with breast cancer are also inconsistent. Only a very few studies have examined biochemical and genetic variables concomitantly in the same cohort. A matched pairs study was carried out to ascertain whether plasma leptin, soluble leptin receptor, free leptin index (leptin/soluble leptin receptor), serum visfatin and selected LEP and LEPR polymorphisms are risk factors for sporadic breast cancer...

Human cytochrome P450 11B2 (CYP11B2) is an essential enzyme in the steroid hormone biosynthesis, which catalyzes the last three reaction steps of the aldosterone synthesis. These reactions comprise a hydroxylation at position C11 of the steroid intermediate deoxycorticosterone yielding corticosterone, followed by a hydroxylation at position C18 yielding 18-hydroxy-corticosterone and a subsequent oxidation of the hydroxyl group at C18, which results in the formation of aldosterone. Alterations in the amino acid sequence of CYP11B2 often cause severe disease patterns...
