It provides prognostic information on cardiovascular events, as reported in the literature. The aim of the present study was to evaluate sP-selectin as a biomarker for cardiovascular mortality in an elderly primary healthcare population, with a focus on possible sex differences. Methods The study included 437 elderly healthy participants from an epidemiological project living in a rural municipality. Clinical examination, echocardiography, and biomarker measurements were performed. All participants were followed for 5.2 years and all mortality was registered. Results sP-selectin was shown to provide significant prognostic information also when including NT-proBNP in a multivariate setting over 5 years with a hazard ratio of 3.12 (95% confidence interval 1.57–6.18) for cardiovascular mortality and a hazard ratio of 2.46 (95% confidence interval 1.39–4.34) for all-cause mortality. The addition of D-dimer to the model did not weaken the results. The sex-specific analyses showed that sP-selectin could be used in both sexes with equally good results; however, there are signs indicating possibly a worse prognosis for women with high-serum levels of sP-selectin. Conclusion sP-selectin is a prognostic biomarker for mortality in an elderly primary healthcare population. Compared with NT-proBNP, sP-selectin is at least as effective. We therefore suggest sP-selectin as an additional biomarker to be used in assessing the elderly to identify those at risk of cardiovascular events. The results presented should be considered hypothesis-generating, and warrant more research.","PeriodicalId":72529,"journal":{"name":"Cardiovascular endocrinology","volume":"36 1","pages":"22–27"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74506927","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In parallel, unanticipated new aspects of an old drug – metformin – have been described. Metformin is a well-established first-line T2DM drug, and increasing number of studies support a role for metformin in preventing T2DM in patients with impaired glucose tolerance and/or impaired fasting glucose. Nonglycemic benefits have also been ascribed to metformin, such as vascular protection, improved lipid profiles, and reduced levels of antifibrinolytic factors. An amelioration in inflammation or endothelial dysfunction has also been shown. In addition, metformin has been used in the treatment of metabolic syndrome, nonalcoholic fatty liver disease, and polycystic ovarian syndrome in insulin-resistant women. There is also a growing body of evidence, mostly in the form of retrospective clinical data and experimental studies, that suggests that metformin may be associated with a decreased risk of developing certain forms of cancer and with a reduction in cancer volume.

A 50-year-old man was referred for resistant and severe hypertension. Laboratory tests showed low serum potassium, primary hyperaldosteronism, and an increase in urinary norepinephrine and metanephrine. An adrenal scan indicated a nodule of the right gland of 35×30 mm with a spontaneous density of 12 HU. The initial diagnosis was that of a Conn’s adenoma. A right adrenalectomy was performed. The tissue removed was a pheochromocytoma. The postoperative course was marked by persistence of high blood pressure. On laboratory tests, levels of urinary metanephrines were normalized, but primary hyperaldosteronism was still present. Thus, the case was finally diagnosed as a bilateral adrenal hyperplasia and unilateral pheochromocytoma. Five cases of involvement of both the adrenal cortex and the medulla have been reported. The scarcity of the cases published favors a fortuitous association. However, other possibilities could be envisaged. A close relation between the cortical and medullary cells has been shown that may play an important role in the regulation of the endocrinal function. Another possibility could be stimulation by adrenaline of the release of adrenocorticotropic hormone and renin, inducing cortical hyperplasia and stimulating the secretion of aldosterone, which could become self-perpetuating. Finally, there may be a genetic predisposition to the endocrine dysplasias involving a double hormonal secretion by the adrenal gland. In conclusion, the association of pheochromocytoma and primary hyperaldosteronism can present in the same patient and needs to be considered on the basis of the clinical and biochemical findings.","PeriodicalId":72529,"journal":{"name":"Cardiovascular endocrinology","volume":"27 1","pages":"39–42"},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82657384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hypothesis was that IL-12 is positively associated with inflammatory markers and risk factors of atherosclerosis. Materials and methodsClinical data were collected from 51 IHD patients by a questionnaire and from basic laboratory blood tests. The association of IL-12 with the biochemical, personal, health status and lifestyle determinants was investigated by regression analysis and analysis of variance. ResultsPlasma IL-12 concentration was associated inversely with the plasma concentration of triglycerides (P=0.001) and homocysteine (P=0.04). However, IL-12 was associated directly with the concentration of high-density lipoprotein cholesterol (P=0.03). IL-12 concentration was not strongly associated with other biochemical parameters nor with the health status, medication or lifestyle determinants. ConclusionThe results suggest that, contrary to the hypothesis, IL-12 was associated inversely with plasma levels of two known risk factors of coronary atherosclerosis (triglycerides, homocysteine) in stable, statin-medicated IHD patients. The lack of association of IL-12 with high-sensitivity C-reactive protein, erythrocyte sedimentation rate and the number of inflammatory cells in blood suggests that moderately elevated IL-12 did not imply ongoing systemic inflammation in these patients. Although increased IL-12 production is a sign of proinflammatory activity, it was associated directly with the plasma high-density lipoprotein cholesterol concentration. Overall, moderately elevated plasma IL-12 concentration may even be a good sign in stable IHD patients.","PeriodicalId":72529,"journal":{"name":"Cardiovascular endocrinology","volume":"122 1","pages":"123–128"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80223747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To confirm the role of insulin resistance and hyperinsulinemia in the pathogenesis of essential hypertension, many studies have been conducted. As no data in this regard are available from our part of the world, our study focuses onestablishing the role of insulin resistance and compensatory hyperinsulinemia in the hypertensive Kashmiri population. Materials and methodsThe study was carried out at a tertiary care hospital from December 2010 to October 2012. A total of 100 individuals aged above 18 years were recruited; 50 were newly detected cases of essential hypertension and 50 were age-matched and sex-matched normal healthy individuals. Serum insulin concentration was measured using an insulin electrochemiluminescence immunoassay. Insulin resistance was determined by HOMA-IR (homeostasis model assessment of insulin resistance). A comparison and contrast analysis of data was carried out using standard statistical methods. ResultsStatistically, the difference in mean fasting blood glucose between the two study groups was significant (P=0.0001). The mean fasting serum insulin level was 15.32±13.76 µU/ml in cases and 8.01±4.08 µU/ml in controls (reference range 2.6–24.9 µU/ml); the difference was statistically significant (P=0.001). The mean value of HOMA-IR in cases was 3.81±3.42 as compared with controls with a mean HOMA-IR value of 1.76±0.93. This difference was statistically significant (P=0.0001). ConclusionEssential hypertension is significantly associated with higher mean fasting insulin levels and insulin resistance. Hyperinsulinemia has a possible role in the pathophysiology of essential hypertension with insulin resistance being the likely predominant mechanism.","PeriodicalId":72529,"journal":{"name":"Cardiovascular endocrinology","volume":"63 1","pages":"129–133"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84734647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The more potent androgen 5&agr;-dihydrotestosterone (DHT) can be formed through conversion of testosterone by the enzyme 5&agr;-reductase. We hypothesized that, because of the presence of DHT in coronary and myocardial tissues, a sexually dimorphic effect can be observed if differences exist in genetics or mRNA expression in androgen-metabolizing enzymes. Materials and methodsmRNA levels of steroidogenic enzymes and the androgen receptor (AR) were investigated in human myocardial tissue samples. Subsequently, all participants in the baseline cohort of the Rotterdam Study (RSI) with successful genotyping and without prevalent myocardial infarction (MI, N=5199) were recruited to study the association between single nucleotide polymorphisms (SNPs) within SRD5A1, SRD5A2, and AKR1C3 and incident MI using Cox regression models. Significant results were replicated within the Atherosclerosis Risk in Communities cohort and the second cohort of the RSII. ResultsThe expression of SRD5A1, AKR1C3, and AR was found in all myocardial samples, whereas HSD17B3 and SRD5A2 expression levels were low and undetectable, respectively. Myocardial SRD5A1 expression was higher in women than in men. Within SRD5A1, SNP rs248805G>A was significantly associated with incident MI in western European women (hazard ratio 1.49; 95% confidence interval 1.19–1.87). This SNP is tightly linked to the HinfI polymorphism in SRD5A1 (rs248793G>C), of which the minor allele has been associated with a higher DHT/T ratio. ConclusionGenetic variation in SRD5A1 is associated with an increased risk of MI in western European women, possibly because of the sex-specific potential of local androgen conversion and effect.","PeriodicalId":72529,"journal":{"name":"Cardiovascular endocrinology","volume":"2 3 1","pages":"134–141"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89325781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
