The clinical effects of acute and recurrent severe hypoglycaemia are associated with significant morbidity including reversible, and permanent, abnormalities of cardiovascular, neurological and cognitive function, in addition to trauma and road traffic accidents.

{"title":"Medical hypothesis: cardiovascular complications of diabetes mellitus-from glucose to insulin and back.","authors":"D Giugliano,&nbsp;R Acampora,&nbsp;F D'Onofrio","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Vascular complications such as atheroma, hypertension and macroangiopathy are the leading causes of morbidity and mortality in diabetic patients. Epidemiological and clinical data linking hyperinsulinaemia to both hypertension and atherosclerosis are inconsistent. Hyperglycaemia is the distinguishing feature of diabetes and it seems a likely candidate for the poor cardiovascular outlook of diabetic patients. High blood glucose levels cause selective impairment of endothelium-dependent relaxation and delay cell replication time of cultured human endothelial cells. These effects of hyperglycaemia are reversed by a number of antioxidants, including superoxide dismutase, catalase and glutathione. Impaired endothelium-dependent vasodilation has been reported both in Type 1 and Type 2 diabetic patient. The evidence for a role of oxygen-derived free radicals in the pathogenesis of vascular diabetic complications can be summarized as follows: 1) glucose can auto-oxidize generating oxygen derived free radicals; 2) elevated levels of oxygen derived free radicals are found in red blood cells, plasma and retina of diabetic animals and patients, and correlate with metabolic control; 3) endogenous antioxidants are all decreased in diabetic tissues and blood; and 4) treatment with different antioxidants may improve many of the metabolic abnormalities reported to occur in diabetic patients. The use of antioxidants to reduce the risk of coronary heart disease in diabetes should await the results of randomized trials with these drugs in the primary and secondary prevention of coronary disease.</p>","PeriodicalId":11111,"journal":{"name":"Diabete & metabolisme","volume":"20 5","pages":"445-53"},"PeriodicalIF":0.0,"publicationDate":"1994-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18857892","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}

Forty-one Type 1 diabetic subjects (DS, age 34.8 +/- 12 yr, DM duration: 10.7 +/- 11.1 yr) were compared to 40 age-matched control subject (CS, age 34.2 +/- 9.1 yr). H (measured by ion-exchange chromatography, units: mumol/l) and several parameters (creatininemia; triglycerides; total, HDL, LDL cholesterol; Lp(a); HbA1c; vitamins B9 and B12) were determined after an overnight fast. H were significantly (p = 0.0001) lower in DS (6.8 +/- 2.2) than in CS (9.5 +/- 2.9). This difference was still apparent in male and female subgroups compared to matched CS (p = 0.003 for each). No correlation was found between H and: lipids, vitamins, renal or retinal status. But H seemed to increase with age, especially in women (p = 0.03; r = 0.32). While there is, at this time, no explanation for the lower H observed in DS, it appears that H cannot directly account for accelerated atherosclerosis in DM. Nevertheless, it remains to be established if high, or even normal, H could identify a subgroup of DS at higher risk of precocious and severe atherosclerosis.</p>","PeriodicalId":11111,"journal":{"name":"Diabete & metabolisme","volume":"20 5","pages":"494-6"},"PeriodicalIF":0.0,"publicationDate":"1994-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18861235","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}
