To study specific features of lipid plasm profile in patients with metabolic syndrome (MS) and manifest disorder of carbohydrate metabolism (CM) as well as their relationships with clinical symptoms of MS.Contents of lipids and apolipoproteins of plasm was measured on an empty stomach in 30 patients (18 females and 12 males) with MS and manifest disorder of CM (diabetes mellitus type 2 at the stage of good and satisfactory compensation of CM without terminal complications).The patients were found to have a subnormal level of HDLP cholesterol, high levels of total cholesterol, LDLP cholesterol and LP alpha. Hypertriglyceridemia occurred only in 31.4% patients (TG200 mg/dl). Mean TG level was 173.69 +/- 21.52 mg/dl. TG and diastolic arterial pressure, fasting glycemia and waist circumference significantly correlated. If the WC/TC was 1.0 and higher, the antiatherogenic plasm factor--HDLP cholesterol--significantly lowered. Positive correlation existed between TG and total cholesterol, LDLP cholesterol, apoB, LDLP cholesterol/HDLP cholesterol, apoB/apoA1, while negative correlation was seen between TG and HDLP cholesterol levels. Patients with hypertriglyceridemia had significantly higher levels of total cholesterol, LDLP cholesterol, apoB, apoB/apoA1.Plasm levels of TG most significantly reflect severity of basic clinical manifestations of MS: abdominal obesity, arterial hypertension, CM compensation. The presence of hypertriglyceridemia in MS patients can be considered as an indicator of high atherogenic potential of plasm.
