The effectiveness of therapies that raise high-density lipoprotein cholesterol (HDL-C) to lower cardiovascular disease risk is currently under debate, and further research into the relationship between HDL-C and function is required.
o investigate whether 2 established HDL-C-raising therapies had differential effects on parameters of high-density lipoprotein (HDL) quality and function, such as HDL particle profile and cholesterol efflux capacity (CEC), in patients with dyslipidemia.
METHODS AND RESULTS:
Sixty-six patients with dyslipidemia, 24 with low HDL-C levels (
Fenofibrate and ER niacin increased plasma HDL-C level similarly, but modulated HDL particle size distribution differently; however, these changes did not result in differential effects on serum CECs.

Severe high-density lipoprotein deficiency associated with autoantibodies against lecithin:cholesterol acyltransferase in non-Hodgkin lymphoma.
Arch Intern Med2012 Jan;172(2):179-81. doi: 10.1001/archinternmed.2011.661.

An antibody against the lecithin:cholesterol acyltransferase (LCAT) enzyme, which negates cholesterol esterification in plasma, causing severe high-density lipoprotein deficiency (HD), was identified in a woman with a large-cell non-Hodgkin lymphoma. Successful treatment of the lymphoma resulted in clearance of the antibody and complete correction of the defective cholesterol esterification and HD. To our knowledge, an acquired LCAT deficiency leading to severe HD has not been reported previously in association with a malignant disease, and this patient represents the first such documented case.

Hypocholesterolaemic effects of lupin protein and pea protein/fibre combinations in moderately hypercholesterolaemic individuals.
Br J Nutr2012 Apr;107(8):1176-83. doi: 10.1017/S0007114511004120.

The present study was aimed to evaluate the effect of plant proteins (lupin protein or pea protein) and their combinations with soluble fibres (oat fibre or apple pectin) on plasma total and LDL-cholesterol levels. A randomised, double-blind, parallel group design was followed: after a 4-week run-in period, participants were randomised into seven treatment groups, each consisting of twenty-five participants. Each group consumed two bars containing specific protein/fibre combinations: the reference group consumed casein+cellulose; the second and third groups consumed bars containing lupin or pea proteins+cellulose; the fourth and fifth groups consumed bars containing casein and oat fibre or apple pectin; the sixth group and seventh group received bars containing combinations of pea protein and oat fibre or apple pectin, respectively. Bars containing lupin protein+cellulose ( - 116 mg/l, - 4·2%), casein+apple pectin ( - 152 mg/l, - 5·3%), pea protein+oat fibre ( - 135 mg/l, - 4·7%) or pea protein+apple pectin ( - 168 mg/l, - 6·4%) resulted in significant reductions of total cholesterol levels (P

Paradoxical decrease in high-density lipoprotein cholesterol with fenofibrate: a quite rare phenomenon indeed.

Some recent clinical reports have suggested that paradoxical decreases in high-density lipoprotein cholesterol (HDL-C) levels after fenofibrate treatment may be quite common. These appear to occur mainly in patients with combined fibrate/statin therapy and possibly in those with low baseline HDL-C. Reports on HDL-C reductions after fenofibrate are possibly supported by the disappointing results in terms of HDL-C responses from the recent FIELD study. A survey on 581 patients treated for 1 year or longer was carried out in our Clinical Center. This indicated that paradoxical HDL-C reductions are a relatively uncommon phenomenon. Not more than 15.3% of the present series showed an HDL-C reduction, mostly of a modest degree. Further, reductions of HDL-C appear to occur mainly in individuals with significant HDL-C elevations (>50 mg/dL), almost never in patients with low HDL-C. Otherwise, there seems to be no impact of a previous diagnosis of diabetes or hypertension on the HDL-C changes. From a very recent pharmacogenomic study on the apo A1/C3/A4/A5 gene cluster, genetic influences appear only to reduce the positive impact of fenofibrate on HDL-C, but do not indicate any risk of occurrence of HDL-C reductions. Also based on our very long experience with this drug, it appears that fenofibrate raises HDL-C levels in the vast majority of treated patients, with a particularly dramatic effect in individuals with low HDL-C and hypertriglyceridemia.

A new noninvasive method for the accurate and precise assessment of varicose vein diameters.

The feasibility and reproducibility of a new ultrasonic method for the direct assessment of maximal varicose vein diameter (VVD) were evaluated. A study was also performed to demonstrate the capacity of the method to detect changes in venous diameter induced by a pharmacologic treatment. Patients with varicose vein disease were recruited. A method that allows the precise positioning of patient and transducer and performance of scans in a gel-bath was developed. Maximal VVD was recorded both in the standing and supine positions. The intraassay reproducibility was determined by replicate scans made within 15 minutes in both positions. The interobserver variability was assessed by comparing VVDs measured during the first phase baseline examination with those obtained during baseline examinations in the second phase of the study. The error in reproducibility of VVD determinations was 5.3% when diameters were evaluated in the standing position and 6.4% when assessed in the supine position. The intramethod agreement was high, with a bias between readings of 0.06 +/- 0.18 mm and of -0.02 +/- 0.19 mm, respectively, in standing and supine positions. Correlation coefficients were better than 0.99 in both positions. The method appears to be sensitive enough to detect small changes in VVDs induced by treatments. The proposed technique provides a tool of potential valid use in the detection and in vivo monitoring of VVD changes in patients with varicose vein disease. The method offers an innovative approach to obtain a quantitative assessment of varicose vein progression and of treatment effects, thus providing a basis for epidemiologic surveys.

Soy milk with a high glycitein content does not reduce low-density lipoprotein cholesterolemia in type II hypercholesterolemic patients.
Ann Nutr Metab2002 ;46(2):88-92.

In order to evaluate acceptability and effectiveness of a partial addition of soy protein to the daily diet in well-established type II hypercholesterolemic individuals, a double-blind study was carried out with a soy milk providing 25 g/day of protein versus an identically formulated cow's milk. Twenty patients with type II hypercholesterolemia, 4 males and 16 females, age range 38-76 years, all with cholesterol levels >7 mmol/l and low-density lipoprotein cholesterol
