Effect of Non-Statin Lipid Lowering and Anti-Obesity Drugs on LDL Subfractions in Patients with Mixed Dyslipidaemia
Bibliographic record
Abstract
Small, dense low density lipoprotein (sdLDL) particles are considered an emerging cardiovascular risk factor. Obese patients with mixed dyslipidaemia frequently have elevated sdLDL cholesterol (sdLDL-C) levels. Therefore, agents that favourably modulate the LDL phenotype may be of clinical value in these patients. We review the efficacy of anti-obesity and lipid lowering drugs other than statins on LDL subfractions in patients with mixed dyslipidaemia primarily focusing on those who are overweight/obese. The literature search was based on PubMed listings up to 26 November 2009. In most studies ezetimibe decreases the large and medium LDL subclasses and, to a lesser extent, the sdLDL particles, while it does not substantially influence LDL size. Fibrates and niacin reduce sdLDL particles and shift LDL size towards large, buoyant LDL particles. More studies are needed to elucidate the effects of fish oils and resins on LDL phenotype. Orlistat and rimonabant have been associated with reductions in sdLDL-C levels along with an increase in LDL particle size. We did not find any literature describing the effect of sibutramine on sdLDL profile. Treatment with fibrates and niacin seems to be beneficial in patients with mixed dyslipidaemia. The addition of orlistat may further improve LDL phenotype in overweight/obese patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
