Diabetes may induce neurophysiological and structural changes in the central nervous system (i.e., diabetic encephalopathy). We here explored whether the levels of neuroactive steroids (i.e., neuroprotective agents) in the hippocampus may be altered by short-term diabetes (i.e., one month). To this aim, by liquid chromatography-tandem mass spectrometry we observed that in the experimental model of the rat raised diabetic by streptozotocin injection, one month of pathology induced changes in the levels of several neuroactive steroids, such as pregnenolone, progesterone and its metabolites (i...

The effects of chronic Dioscorea esculenta administration and exercise training on muscle sex steroid hormone levels and insulin resistance in type 2 diabetes rats was assessed. Twenty-wk-old male Otsuka Long Evans Tokushima Fatty (OLETF) rats were assigned randomly to the control, D. esculenta treatment, D. esculenta with 5α-reductase inhibitor treatment, or the exercise training groups (running at 25 m/min for 1 h, 5 d/wk; n = 10 each group). Eight weeks of D. esculenta treatment or exercise training significantly attenuated the increase in plasma insulin and fasting glucose levels...

Glucocorticoids (GCs) are well known to induce insulin resistance. However, the effect of GCs on insulin secretion has not been well characterized under physiological conditions in human. We here evaluated the effect of GCs on insulin secretion/ß-cell function precisely in a physiological condition. A population-based study of 1,071 Japanese individuals enrolled in the 2014 Iwaki study (390 men, 681 women; aged 54.1 ± 15.1 years), those excluded individuals taking medication for diabetes or steroid treatment, were enrolled in the present study...

Regular resistance exercise induces skeletal muscle hypertrophy and improvement of glycemic control in type 2 diabetes patients. Administration of dehydroepiandrosterone (DHEA), a sex steroid hormone precursor, increases 5α-dihydrotestosterone (DHT) synthesis and is associated with improvements in fasting blood glucose level and skeletal muscle hypertrophy. Therefore, the aim of this study was to investigate whether increase in muscle DHT levels, induced by chronic resistance exercise, can contribute to skeletal muscle hypertrophy and concomitant improvement of muscular glucose metabolism in type 2 diabetic rats...

Characterization of mice with cell-specific deletion or overexpression of the mineralocorticoid receptor (MR) shed a new light on its role in health and disease. Pathophysiological MR activation contributes to a plethora of deleterious molecular mechanisms in the development of cardiorenal diseases like chronic kidney disease (CKD) and heart failure (HF). Accordingly, the available steroidal MR antagonists (MRAs) spironolactone (first generation MRA) and eplerenone (second generation MRA) have been shown to be effective in reducing cardiovascular (CV) mortality and morbidity in patients with chronic HF and a reduced left ventricular ejection fraction (HFrEF)...

Elevated levels of glucocorticoid, a steroid hormone released in response to stress, have been implicated in the pathophysiology of diabetes, which is now known to extend its effect on brain functions. Hence, we aimed to investigate the status of brain insulin signaling in response to dexamethasone (a synthetic glucocorticoid) treatment in female Charles Foster rat. This model exhibited pronounced hyperinsulinemia and glucose intolerance with loss in appetite and body weight. Immunoblotting of insulin receptor (INSR)-PI3kinase-AKT demonstrated reduced insulin signaling in hypothalamus but no change in hippocampus, cortex, and cerebellum in dexamethasone-treated rats as compared to vehicle-treated rats, signifying the diversity of distribution and function of insulin in different brain regions...

Steroid-induced hyperglycaemia is a common problem faced by endocrinologists in hospital wards. In this issue of Diabetologia, Popovic and colleagues (DOI 10.1007/s00125-016-4091-4 ) have conducted a subanalysis within a randomised controlled trial of prednisone therapy for community-acquired pneumonia. The authors found that the presence of diabetes or hyperglycaemia related to steroid therapy did not attenuate the clinical benefits of steroid therapy. The relevance and possible implications of these findings are discussed...

Corticosteroids are key medications to treat pulmonary diseases. A variety of medications, doses, administration route, and duration of corticosteroids were chosen for each of pulmonary diseases. Although corticosteroids are potent medications, they often cause serious adverse effects such as osteoporosis, diabetes, and immunosuppression. Thus, physicians have to properly assess the risk of adverse effects to prevent them. In this review, we discuss the risk of osteoporosis by corticosteroids that are prescribed for pulmonary diseases...

Steroid-induced diabetes mellitus (SIDM) poses a unique challenge for the physician and ophthalmologist when faced with chronic recurrent uveitis controlled only with systemic steroids. We report a unique case where SIDM improved significantly following administration of intravitreal dexamethasone. A 53-year-old female had a history of recurrent idiopathic anterior uveitis that required oral steroids for control despite orbital floor steroids and systemic immunosuppression. After 9 years of oral steroid treatment she was diagnosed with SIDM necessitating insulin therapy...

Glucocorticoids (GCs) are steroid hormones that exert important physiological actions on metabolism. Given that GCs also exert potent immunosuppressive and anti-inflammatory actions, synthetic GCs such as prednisolone and dexamethasone were developed for the treatment of autoimmune- and inflammatory-related diseases. The synthetic GCs are undoubtedly efficient in terms of their therapeutic effects, but are accompanied by significant adverse effects on metabolism, specifically glucose metabolism. Glucose intolerance and reductions in insulin sensitivity are among the major concerns related to GC metabolic side effects, which may ultimately progress to type 2 diabetes mellitus...

We present a case of Aspergillus fumigatus endophthalmitis complicated by necrotizing scleritis in a 68-year-old man with diet-controlled diabetes, after retinal detachment repair. He was initially treated with systemic steroids for surgically induced necrotizing scleritis following routine pars plana vitrectomy. An additional diagnosis of endophthalmitis was made when the patient developed a hypopyon. Repeat vitreous culture isolated Aspergillus fumigatus. Symptoms improved following antifungal treatment leaving the patient with scleromalacia and an advanced postoperative cataract...

Obesity is characterized by a disruption in energy balance regulation that results in an excess accumulation of body fat. Its increasing prevalence poses a major public health concern because it is a risk factor for a host of additional chronic conditions, including type 2 diabetes, hypertension, and cardiovascular disease. Obesity is increasingly recognized as a growing cause of cancer risk. In particular excessive adipose expansion during obesity causes adipose dysfunction and inflammation that can regulate tumor growth...
