IntroductionSchizophrenia (SCZ) is frequently associated with metabolic symptoms including dyslipidaemia, hyperinsulinemia, type 2 diabetes and obesity. In fact, SCZ patients have been reported to present higher prevalence of these conditions than general population, commonly associated to second generation antipsychotic therapy. Recent studies, however, have demonstrated that peripheral metabolic disturbances can appear at disease onset or drug-naïve patients.Objectives/aimsTo assess metabolic disturbances in first episode and/or drug-naïve SCZ patients.MethodsWe conducted a literature review through Pubmed search for MeSH: schizophrenia, metabolism, glucose, insulin. Controlled studies on first episode and/or drug-naïve SCZ patients were included.ResultsSeveral studies showed no change in SCZ patients’ fasting blood glucose, while others found increased glucose levels and impaired glucose tolerance in SCZ patients compared to healthy controls in several recent studies. Hyperinsulinemia and insulin resistance have also been identified in antipsychotic-naïve SCZ patients and it has been suggested that early onset patients are more likely to present insulin resistance. In addition, there's evidence of increased circulating levels of chromogranin A, pancreatic polypeptide, prolactin, cortisol, progesterone, thus emphasising that multiple components of the hypothalamic-pituitary-adrenal-gonadal axis may be affected in SCZ. These elevations were associated to normal glycaemia suggesting there may be insulin intolerance during early stages of SCZ, requiring an increased secretion from pancreatic Bcells to maintain normal glucose levels.ConclusionsRecent studies of first onset and/or drug-free schizophrenia patients have shown impaired fasting glucose tolerance, hyperinsulinemia and insulin intolerance, suggesting that metabolic abnormalities may play a role in SCZ onset and pathophysiology.Disclosure of interestThe authors have not supplied their declaration of competing interest.

BackgroundSchizophrenia patients have a higher prevalence of type 2 diabetes mellitus with impaired glucose tolerance (IGT) than normals. We examined the relationship between IGT and clinical phenotypes or cognitive deficits in first-episode, drug-naïve (FEDN) Han Chinese patients with schizophrenia.MethodA total of 175 in-patients were compared with 31 healthy controls on anthropometric measures and fasting plasma levels of glucose, insulin and lipids. They were also compared using a 75 g oral glucose tolerance test and the homeostasis model assessment of insulin resistance (HOMA-IR). Neurocognitive functioning was assessed using the MATRICS Consensus Cognitive Battery (MCCB). Patient psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS).ResultsOf the patients, 24.5% had IGT compared with none of the controls, and they also had significantly higher levels of fasting blood glucose and 2-h glucose after an oral glucose load, and were more insulin resistant. Compared with those patients with normal glucose tolerance, the IGT patients were older, had a later age of onset, higher waist or hip circumference and body mass index, higher levels of low-density lipoprotein and triglycerides and higher insulin resistance. Furthermore, IGT patients had higher PANSS total and negative symptom subscale scores, but no greater cognitive impairment except on the emotional intelligence index of the MCCB.ConclusionsIGT occurs with greater frequency in FEDN schizophrenia, and shows association with demographic and anthropometric parameters, as well as with clinical symptoms but minimally with cognitive impairment during the early course of the disorder.

ABSTRACTProbiotic supplements have demonstrated efficacy in improving metabolic abnormalities and may prevent antipsychotic-induced metabolic disturbance and weight gain. A few studies in rodents have found that antipsychotic-induced metabolic dysfunctions are associated with the altered composition of gut microbiota. Here, we conducted a randomized-controlled clinical trial to determine the effectiveness and safety of probiotic supplements on antipsychotic-induced metabolic disturbance and weight gain. Patients with drug-naïve first-episode schizophrenia were randomized to receive either olanzapine plus probiotics or olanzapine monotherapy and scheduled to evaluate with follow-ups for clinical and metabolic profiles. After a treatment of 12 weeks with addition of probiotics, the increase of mean fasting insulin was significantly lower than olanzapine monotherapy. Insulin resistance increased considerably in the olanzapine plus probiotics, but also significantly lower than olanzapine monotherapy. We noted a difference in the increase in body mass index and body weight between treatments at a nominal level of significance, but it became non-significant after adjusting for appetite increase. Probiotics concurrently used with olanzapine is effective and safe in attenuating antipsychotic-induced elevation of fasting insulin and insulin resistance, but not the weight gain in drug-naïve first-episode schizophrenia. Further study is warranted to assess the longer-term maintenance of efficacy and safety.

ABSTRACT Six cases of congenital generalized lipodystrophy have been studied at different ages from infancy to adolescence with regard to glucose tolerance, insulin secretion, and insulin sensitivity. During the first few years of life there is normal glucose tolerance. The fasting immuno-reactive insulin (IRI) levels are either slightly elevated or normal. The IRI response to glucose is exaggerated and prolonged, at least from the third year of life. Some degree of insulin resistance is already present in infancy. From the age of 8–10 years glucose tolerance decreases rapidly. The fasting IRI levels are usually grossly elevated, while fasting plasma glucose levels are only moderately elevated or normal. The IRI responses to oral and iv administered glucose, and to tolbutamide are exaggerated; the insulinogenic indices are high. Cortisone primed glucose tolerance tests become abnormal. Insulin resistance is marked, and increases with age. After cessation of growth at approximately 12 years of age, frank diabetes with fasting hyperglycaemia and diabetic glucose tolerance curves developed in the one patient followed beyond this age. Her fasting IRI was increased, but there was a poor IRI response to glucose stimulation, suggesting a partial exhaustion of the β-cells. Her initial IRI response to tolbutamide was still good, but not as brisk as in the younger patients. This type of diabetes is quite different from the juvenile form, and also from the diabetes of older age. It may be causally related to the lack of an adequate adipose organ necessary for the disposal of excesses of glucose, or possibly related to another anti-insulin mechanism.

Abstract Objectives Chronic metabolic disturbances related to cancer treatment are well reported among survivors of pediatric acute lymphoblastic leukemia (ALL). However, few studies have investigated the incidence of these complications during the phase of chemotherapy. We evaluated the incidence of acute metabolic complications occurring during therapy in our cohort of patients diagnosed with ALL. Methods A prospective study involving 50 ALL pediatric patients diagnosed and treated between 2012 and 2016 in our oncology unit. We collected weight, blood pressure, fasting plasma glucose and hemoglobin A1C (HBA1c) levels during the two years of therapy. Results Obesity and overweight occurred in 43 and 25%, respectively among patients and have been reached at 12 months of chemotherapy. About 26% of the patients developed high blood pressure and 14% experienced hyperglycemias without meeting diabetes criteria. There was a significant decrease of HBA1c levels between the beginning and the end of therapy (p<0.0001). Conclusions Increase of body mass index in our ALL pediatric patients occurred during the first months of therapy and plateaued after a year of treatment. We should target this population for early obesity prevention. HbA1c levels measured during therapy did not reveal diabetes criteria. Hence, fasting blood glucose levels are sufficient to monitor ALL pediatric patients’ glycemia.

Objective: This study was aimed to determine the correlation between vitamin D and insulin resistance in women with PCOS. Method: This study was correlational analytic with cross-sectional approach to 34 women diagnosed with PCOS based on ultrasonography. Waist circumference and fasting blood glucose (FBG) represented insulin resistance. Women with hormonal therapy and vitamin D supplementation were not included to this study. This study used consecutive sampling method. Result: The average of age was 25.6±6.1 years old. Waist circumference and fasting blood glucose (FBG) represented insulin resistance. The average of waist circumference and FBG were 87.6±12.4 cm and 86.2±27.9 mg/dl, respectively. The mean of vitamin D levels was 11,5±3,6 ng/ml. According to Spearman’s correlation, vitamin D levels were weak negative correlated with waist circumference (r=-0.2; p>0.05) and FBG (r= -0,1; p>0,05), it statistically was not significant. Conclusion: There is weak negative correlation between vitamin D and metabolic syndrome in PCOS patients.

Compound Danshen dripping pills (CDDP) is widely used for the treatment of coronary arteriosclerosis and ischemic heart diseases for decades of years. In our study, we interestingly discovered the effects and mechanism of CDDP on insulin resistance that increase the risk factor of cardiovascular diseases. Effects of CDDP on fasting blood glucose, the insulin tolerance test (ITT), the oral glucose tolerance test (OGTT), hepatic function, and underlying mechanism were analyzed in ob/ob mice. CDDP was found improving the impaired insulin signal sensitivity of ob/ob mice by ameliorating insulin and glucose tolerance, improving hepatic phosphorylation of the insulin receptor substrate-1 on Ser 307 (pIRS1) of ob/ob mice, and restoring hepatic function by decreasing serum ALT and AST, which increased in ob/ob mice serum. Decreasing hepatic phosphorylation of pancreatic ER kinase (PERK) and inositol-requiring enzyme-1 (IRE1) regulating hepatic ER stress in the liver of ob/ob mice were increased by CDDP. Furthermore, CDDP was also found stimulating ob/ob mice hepatic autophagy by increasing the expression of Beclin1 and LC3B, while decreasing P62 expression. Our study discovered an important role of CDDP on improving ob/ob mice insulin resistance and liver function probably through relieving hepatic ER stress and stimulating hepatic autophagy, which would broaden the application value and provide more benefits for treating cardiovascular patients. This trial is registered with NCT01659580.

Background. Previous studies have suggested that Fetuin-B seems to be a secreted adipokine related to metabolic diseases. However, the results have been inconsistent. Here, our objective is to investigate the changes in circulating Fetuin-B levels in women with polycystic ovary syndrome (PCOS) and analyze the association of Fetuin-B and insulin resistance (IR). Methods. The current study is comprised of a cross-sectional study and a series of interventional studies. Oral glucose tolerance test (OGTT) and euglycemic-hyperinsulinemic clamp (EHC) were engaged to assess glucose tolerance and insulin sensitivity. Serum Fetuin-B levels were determined by ELISA. Results. Serum Fetuin-B and TNF-α levels were markedly increased in women with PCOS compared to healthy women. Circulating Fetuin-B was positively associated with body mass index, waist-to-hip ratio, the percentage of body fat (FAT%), systolic blood pressure, triglyceride, low-density lipoprotein cholesterol, fasting blood glucose, 2 h blood glucose after glucose overload, fasting insulin, 2 h insulin after glucose overload, HOMA-insulin resistance index (HOMA-IR), the area under the curve for insulin (AUCi), AUCg, and TNF-α, while negatively associated with M value and follicular stimulating hormone (FSH). During the EHC, Fetuin-B levels were found to be significantly increased in PCOS women. After a glucose challenge, serum Fetuin-B levels in healthy women were significantly increased. Lipid infusion reduced serum Fetuin-B levels in 30 healthy subjects. After six months of glucagon-like peptide-1 receptor agonist (GLP-1RA) intervention, serum Fetuin-B concentrations in PCOS women markedly decreased following ameliorated IR. Conclusion. Our results indicate that Fetuin-B may be a biomarker of IR in individuals with PCOS. This trial is registered with ChiCTR-IIR-16007901.

BackgroundSchizophrenia shortens life, e.g. through suicide and obesity-related diseases such as type 2 diabetes mellitus. It is assumed that medications play a major role, but most of the evidence for this comes from studies poorly controlled for variables such as lifestyle and medication status.AimsTo determine whether schizophrenia is associated (independently of medication) with the development of certain metabolic disturbances and whether these might be explained by stress axis dysfunction.MethodLiterature review.ResultsMost studies did not control for confounding factors such as previous usage of medication, lifestyle, age and ethnicity. A few conducted in drug-naive patients with first-episode schizophrenia appear to indicate that these patients have higher than expected rates of visceral obesity and impaired fasting glucose concentrations, which may be related to a subtle disturbance of the hypothalamic–pituitary–adrenal axis.ConclusionsSchizophrenia is independently associated with physical illnesses that have a metabolic signature. Therefore, patients need to have a thorough physical assessment at diagnosis and at regular intervals thereafter. Metabolic disturbances have been found in drug-naïve patients with first-episode illness and may be an inherent part of the illness.

Estrogen is an important regulator of metabolic syndrome, a collection of abnormalities including obesity, insulin resistance/glucose intolerance, hypertension, dyslipidemia, and inflammation, which together lead to increased risk of cardiovascular disease and diabetes. The role of the G protein-coupled estrogen receptor (GPER/GPR30), particularly in males, in these pathologies remains unclear. We therefore sought to determine whether loss of GPER contributes to aspects of metabolic syndrome in male mice. Although 6-month-old male and female GPER knockout (KO) mice displayed increased body weight compared with wild-type littermates, only female GPER KO mice exhibited glucose intolerance at this age. Weight gain in male GPER KO mice was associated with increases in both visceral and sc fat. GPER KO mice, however, exhibited no differences in food intake or locomotor activity. One-year-old male GPER KO mice displayed an abnormal lipid profile with higher cholesterol and triglyceride levels. Fasting blood glucose levels remained normal, whereas insulin levels were elevated. Although insulin resistance was evident in GPER KO male mice from 6 months onward, glucose intolerance was pronounced only at 18 months of age. Furthermore, by 2 years of age, a proinflammatory phenotype was evident, with increases in the proinflammatory and immunomodulatory cytokines IL-1β, IL-6, IL-12, TNFα, monocyte chemotactic protein-1, interferon γ-induced protein 10, and monokine induced by interferon gamma and a concomitant decrease in the adipose-specific cytokine adiponectin. In conclusion, our study demonstrates for the first time that in male mice, GPER regulates metabolic parameters associated with obesity and diabetes.
