[Dyslipidemia in diabetes mellitus: significance, diagnosis and treatment].
Dyslipidemias are frequent in diabetic subjects: they increase the risk for atherosclerosis, in addition to the risk of diabetes mellitus per se. The pathogenesis of dyslipidemias differs between type I and type II diabetes: untreated type I diabetic subjects demonstrate frequently increased triglyceride concentrations due to diminished removal of triglyceride-containing particles, as a result of diminished activity of lipoprotein lipase. In addition, more triglycerides are produced due to increased lipolysis and increased free fatty acid supply to the liver. Type II diabetic subjects demonstrate very low density lipoprotein (VLDL) over-production due to obesity, insulin resistance and caloric overconsumption. In addition, triglyceride removal may be diminished due to diminished lipoprotein lipase activity when diabetes mellitus is poorly controlled. In addition, high density lipoprotein (HDL) is frequently lowered. During decompensation low density lipoprotein (LDL) concentrations may also increase. LDL particle composition is frequently abnormal. A severe dyslipidemia in diabetes mellitus is frequently a combined effect of diabetes mellitus and a congenital lipoprotein abnormality. The evaluation and treatment of dyslipidemias in diabetic subjects should be performed similarly to non-diabetics according to the guidelines published recently by the Working Group 'Lipids' of the Swiss Foundation of Cardiology. Additional accents in diabetic subjects are necessary. It is recommended that serum cholesterol, triglycerides and HDL are determined in every patient when diabetes mellitus is diagnosed. If serum cholesterol is greater than 6.5 mmol/l and the cholesterol/HDL-ratio is greater 6.5, dietary treatment should be reinforced; if its effect is insufficient, drug therapy should be considered.(ABSTRACT TRUNCATED AT 250 WORDS)
