DEAE-Dextran in the treatment of primary hypercholesterolemia and/or hypercholesterolemia combined with hypertriglyceridemia. A multicentric randomized study on the efficacy of DEAE-Dextran compared with Cholestyramine.

This study was carried out to verify the therapeutic homogeneity between DEAE-Dextran and Cholestyramine. Blood levels of total cholesterol, HDL, LDL and triglycerides were evaluated in 202 patients affected by dyslipidemia and treated with DEAD-D at 2.5 g/day or with Cholestyramine at 12 g/day for 30 days. At the end of treatment both drugs caused significant reduction of total cholesterol, LDL and triglycerides blood levels; DEAD-D was generally more effective than Cholestyramine, in particular on triglycerides values (30.6% and 13.7% of reduction respectively), and produced also a significant increase in HDL cholesterol, differently from Cholestyramine that was ineffective on this parameter.

[Effect of short-term use of omega-3-type polyunsaturated fatty acids in subjects with hypertriglyceridemia].

OBJECTIVE: To study the effect of omega-3 polyunsaturated fatty acid supplementation on lipid profile in hypertriglyceridaemic patients. SETTING: General practice. DESIGN: Prospective, double blind study of 12 weeks' duration. PATIENTS AND METHODS: Eight patients received fish oil (1800 mg C20: 5 omega-3 eicosapentaenoic acid (EPA) and 1200 mg C22:6 omega-3 docosahexaenoic acid (DHA). Nine patients received corn oil (3000 mg C18: 2 omega-6 linoleic acid daily). RESULTS: Lipid profile analysis showed a decrease in triglyceride levels after fish oil supplementation. An unexpected and unexplained finding was the rise in total cholesterol and LDH cholesterol with corn oil supplementation. CONCLUSION: Fish oil causes a decrease in triglyceride levels in hypertriglyceridaemic patients.

[Severe hypertriglyceridemia and acute pancreatitis in pregnancy. A case report].

We report the case of a 32-year old woman who developed major hypertriglyceridaemia complicated by acute pancreatitis at 35 weeks of pregnancy. Caesarean section was performed within 24 hours of admission. After delivery, hypocaloric parenteral feeding without lipid emulsion was initiated. The outcome was favourable, and the patient could resume oral feeding after 5 weeks. The incidence of pancreatitis during pregnancy is 1 in 1,000 to 3,000 pregnancies. In the identification of the metabolic abnormality in our patient the differential diagnosis was between type III and type IV hyperlipaemia, according to Fredrickson's classification.

Increased affinity of LDL for their receptors after acipimox treatment in hypertriglyceridemia.

The regulation of cellular LDL metabolism by hypertriglyceridemic LDL was tested before and after treatment with acipimox, a nicotinic acid derivative, in 11 type IV hyperlipidemic patients. Large, less dense LDL particles were found in plasma after acipimox treatment. HDL subfractions were only slightly modified, with an increase of dense, cholesteryl ester-enriched and triglyceride-poor HDL3 particles. The LDL (B, E) receptor activity in human skin fibroblasts of LDL isolated before and after treatment was also evaluated. Hypertriglyceridemic LDL proved rather inefficient in regulating receptor activity, with a close to 30% lower capacity than normal LDL to inhibit receptor-mediated uptake and degradation of 125I-LDL. This abnormality was fully corrected after acipimox. The reported findings indicate that acipimox treatment in type IV patients can normalize the defective interaction of hypertriglyceridemic LDL with the LDL (B, E) receptor.
