Diabetes and ischemic heart disease:double jeopardy with regard to depressive mood and reduced quality of life

The aim of this study was to test i) whether patients having diabetes and ischemic heart disease (IHD), i.e., patients suffering from two chronic diseases, demonstrate a higher degree of chronic stress when compared with patients suffering from IHD alone, and ii) whether suffering from the two chronic diseases results in an elevation in specific elements of the chronic stress concept. A total of 361 participants with IHD were included, of whom 47 suffered from concomitant diabetes. Stress was measured by pressure pain sensitivity (PPS) and by the following questionnaires: the Major Depression Inventory (MDI), the SF-36 Quality of Life questionnaire (SF-36 QOL), the WHO-5 Well-being Index, and the clinical stress signs (CSSs) scale. Participants with diabetes and IHD had a higher MDI score, a lower SF-36 physical component summary score, and a lower score of several sub-measurements of the SF-36 mental component score when compared with patients with IHD without diabetes. No significant differences were observed regarding stress measured by the PPS measure, the WHO-5 Well-being Index, or the number of CSSs. In conclusion, the combination of diabetes and IHD seems to be associated with increased depressive symptoms, lower overall physical QOL, and reduced mental QOL on several sub-elements of the questionnaire. This should be recognized in the management of patients with double diagnoses

Galectin-3 and fibulin-1 in systolic heart failure:relation to glucose metabolism and left ventricular contractile reserve

Abstract Background Heart failure (HF) patients with diabetes (DM) have an adverse prognosis and reduced functional capacity, which could be associated with cardiac fibrosis, increased chamber stiffness and reduced left ventricular (LV) contractile reserve. Galectin-3 (Gal-3) and fibulin-1 are circulating biomarkers potentially reflecting cardiac fibrosis. We hypothesize that plasma levels of Gal-3 and fibulin-1 are elevated in HF patients with DM and are associated with reduced LV contractile reserve in these patients. Methods A total of 155 patients with HF with reduced ejection fraction underwent a low-dose dobutamine echocardiography and blood sampling for biomarker measurements. Patients were classified according to history of DM and an oral glucose tolerance test (OGTT) as: normal glucose tolerance (NGT) ( n \u2009=\u200970), impaired glucose tolerance (IGT) ( n \u2009=\u200925) and DM ( n \u2009=\u200960). Results Galectin-3 levels were elevated in DM patients as compared to non-diabetic patients ( P \u2009=\u20090.02), while higher fibulin-1 levels were observed in HF patients with IGF and DM ( P \u2009=\u20090.07). Reduced LV contractile reserve was associated with increasing Gal-3 levels (\u3b2\u2009=\u2009\u22120.19, P \u2009=\u20090.03) although, this association was attenuated after adjustment for estimated glomerular filtration rate ( P \u2009=\u20090.66). Fibulin-1 was not associated with LV contractile reserve ( P \u2009=\u20090.71). Conclusions Galectin-3 and fibulin-1 levels were elevated in HF patients with impaired glucose metabolism. However, reduced LV contractile reserve among HF patients with DM does not to have an independent impact on plasma Gal-3 and fibulin-1 levels

Prevalence and severity of diabetic retinopathy in pregnant women with diabetes—time to individualize photo screening frequency

AIMS: To evaluate the prevalence and severity of diabetic retinopathy including macular oedema in pregnant women with diabetes and to identify women in whom the frequency of retinal screening can be reduced to minimize the burden of health care visits. METHODS: A cohort study of 348 women with pre‐existing diabetes were routinely screened with retinal photo in early (12 weeks) and late pregnancy (27 weeks). Diabetic retinopathy was classified in five stages in accordance with National Danish Guidelines based on the eye with the highest retinopathy level. Sight‐threatening retinopathy was defined as the presence of proliferative retinopathy and/or clinically significant macular oedema (CSMO). RESULTS: Retinopathy was present in 52% (116/223) vs. 14% (17/125), with sight‐threatening retinopathy in 16% (35/223) vs. 6% (7/125) of women with type 1 and type 2, respectively. Women without retinopathy in early and late pregnancy were characterized by shorter diabetes duration (p < 0.0001 and p = 0.008) and predominance of type 2 diabetes. Amongst the 50% (175/348) of the cohort having no retinopathy in early pregnancy and HbA1c<53 mmol/mol (7.0%), none developed sight‐threatening retinopathy and 94% (165/175) remained without any retinopathy during pregnancy. Development of sight‐threatening retinopathy was mainly observed in women with retinopathy in early pregnancy. Treatment for sight‐threatening retinopathy was given to a minority (2.7 and 2.4%, respectively). CONCLUSION: Good glycaemic control and no retinopathy was seen in a large proportion of women in early pregnancy and none of these women developed sight‐threatening retinopathy. The frequency of retinal screening can probably be safely reduced during pregnancy in these women

Limited Diagnostic Utility of Chromogranin A Measurements in Workup of Neuroendocrine Tumors

Background: Plasma chromogranin A (CgA) is related to tumor burden and recommended in the follow-up of patients diagnosed with neuroendocrine tumors (NETs). The use of CgA in the workup of a suspected NET is more questionable. Objective: To assess the positive predictive value (PPV) of CgA plasma concentrations above the upper reference limit (URL) in patients with suspected NET. Method: Patients referred to the NET Centre, Rigshospitalet, Copenhagen from 2015 to 2019 with clinically suspected NET were included if a CgA measurement was performed prior to referral. The utility of CgA was assessed by comparing pre-referral CgA concentrations to the outcome of a thorough workup. In 47 selected cases with continuously unexplained elevated CgA concentrations, a processing-independent analysis (PIA) for CgA was performed. Results: A total of 197 patients were included. NET was ultimately diagnosed in 25 patients. CgA plasma concentrations were above the URL (elevated) in 19/25 patients diagnosed with NET. In total, 167/197 had elevated CgA concentrations at referral. The positive predictive value (PPV) of elevated CgA concentration was 11% (19/167). Proton pump inhibitor (PPI) treatment was identified as the possible cause of CgA elevation in 55/148 patients with falsely elevated CgA. CgA concentration was normal in 28/47 patients when using PIA. Conclusion: Our data do not support using measurement of CgA for screening when NET is suspected since the PPV was rather low. PPI treatment is a common cause of increased CgA concentrations and should always be discontinued before CgA measurement. PIA of CgA could be a way of excluding NET when suspicion is based primarily on elevated CgA
