Association between non-HDL-C/HDL-C ratio and carotid atherosclerosis in postmenopausal middle-aged women.

Background: A novel lipid relation, the non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol (non-HDL-C/HDL-C) ratio gathers information on all atherogenic and antiatherogenic particles on a single date. The relationship between this lipid marker and the presence of carotid atherosclerotic plaque (CAP) in postmenopausal women is unknown. Methods: Postmenopausal women in primary prevention up to 70 years of age were recruited. Association between the non-HDL-C/HDL-C ratio and presence of CAP, assessed by ultrasonography, was analyzed. Receiver operating characteristic (ROC) curve analysis was performed. Results: A total of 440 females with a mean age of 58.1 ± 5.3 years were recruited. The mean non-HDL-C/HDL ratio was 3.1 ± 1.2 and 28.2% of woman had CAP. A positive relationship was seen between quintiles of the non-HDL-C/HDL-C ratio and prevalence of CAP (p < 0.001). Regardless of other risk factors, women with higher non-HDL-C/HDL-C ratios had a greater chance of having CAP (odds ratio 1.30, 95% confidence interval: 1.07-1.58, p = 0.009). In the ROC curve analysis, the area under the curve of the non-HDL-C/HDL ratio for detecting CAP was 0.703 (95% confidence interval: 0.640-0.765) and the optimal cut-off point was 3.0 (Youden index 0.395). Conclusion: The present study suggests that the non-HDL-C/HDL-C ratio might be a strong marker for predicting the risk of CAP in postmenopausal women.

Inhibidores de la proproteína convertasa plasmática subtilisina kexina tipo 9 y riesgo de cataratas: revisión sistemática y metaanálisis / Plasma proprotein convertase subtilisin/kexin type 9 inhibitors and cataract risk: A systematic review and meta-analysis

Antecedentes: El marcado descenso en los niveles de C-LDL producidos por los inhibidores de la proproteína convertasa plasmática subtilisina kexina tipo 9 (iPCSK9) podría asociarse con un mayor riesgo de cataratas. Métodos: Realizamos un metaanálisis que incluyó ensayos clínicos aleatorizados y controlados con iPCSK9, solos o combinados con otros fármacos hipolipidemiantes, que reportaron nuevos casos de cataratas, buscando en PubMed/Medline, bases de datos de EMBASE y Cochrane Clinical Trials. Se utilizó un modelo de efectos fijos y se realizó una metarregresión evaluando la relación entre el C-LDL intratratamiento y el riesgo de desarrollar cataratas. Resultados: Se tomaron en cuenta 5 estudios elegibles con iPCSK9 que incluyeron 83.492 pacientes para el análisis, refiriendo 531 nuevos casos de cataratas en el grupo con iPCSK9 frente a 532 en el grupo placebo. La terapia con iPCSK9 no se asoció con un mayor riesgo de presentar cataratas (OR: 0,96; IC 95%: 0,85-1,08; p = 0,86, I2: 0%]. Asimismo, no se encontró una asociación significativa entre la diferencia de C-LDL intratratamiento entre las ramas de los estudios y el riesgo de cataratas. Conclusión. En nuestro análisis, la utilización de iPCSK9 no se asoció con un mayor riesgo de cataratas

Background: The marked decrease in LDL-C levels produced by the inhibitors of the plasma proprotein convertase subtilisin/kexin type 9 (iPCSK9) could be associated with an increased risk of cataracts. Methods: A meta-analysis was performed that included randomised clinical trials controlled with iPCSK9, alone, or in combination with other lipid-lowering drugs, which reported new cases of cataracts, by searching PubMed/Medline, databases of EMBASE and Cochrane Clinical Trials. A fixed-effect model was used, and a meta-regression was carried out evaluating the relationship between intra-treatment LDL-C and the risk of developing cataracts. Results: Five eligible studies of iPCSK9 including 83,492 patients were taken into account for the analysis, and 531 new cases of cataracts in iPCSK9 group vs. 532 in placebo group were diagnosed. The iPCSK9 therapy was not associated with an increased risk of cataracts [OR: 0.96, 95% CI: 0.85-1.08; P = .86, I2: 0%]. Likewise, no significant association was found between on-treatment LDL-C levels, differences between study arms, and new cases of cataracts. Conclusion: In this analysis, the use of iPCSK9 was not associated with an increased risk of cataracts

CONCLUSION: In this analysis, the use of iPCSK9 was not associated with an increased risk of cataracts.

Therapy with cholesteryl ester transfer protein (CETP) inhibitors and diabetes risk.

BACKGROUND: Cholesteryl ester transfer protein (CETP) inhibitors are a class of drugs that targets the CETP enzyme to significantly increase serum high-density lipoprotein cholesterol (HDL-C) and decrease low-density lipoprotein cholesterol (LDL-C) levels. As HDL-C has potential antidiabetic properties, and the beneficial effects of CETP drugs on glucose homoeostasis have not been sufficiently studied, the aims of this study were: (1) to evaluate the effect of CETP inhibitors on the incidence of diabetes; and (2) to assess the association between CETP inhibitor-induced changes in HDL-C levels and incidence of diabetes. METHODS: A meta-analysis was performed of randomized controlled clinical trials of CETP inhibitor therapy, either alone or combined with other lipid-lowering drugs, reporting data from new cases of diabetes with a minimum of 6 months of follow-up, after searching the PubMed/MEDLINE, Embase and Cochrane Controlled Trials databases. A fixed-effects meta-regression model was then applied. RESULTS: Four eligible trials of CETP inhibitors, involving a total of 73,479 patients, were considered for the analyses, including 960 newly diagnosed cases of diabetes in the CTEP inhibitor group vs 1086 in the placebo group. CETP inhibitor therapy was associated with a significant 12% reduction in incidence of diabetes (OR: 0.88, 95% CI: 0.81-0.96; P=0.005). Assessment of the relationship between on-treatment HDL-C and the effect of CETP inhibitors showed a statistically non-significant trend (Z=-1.13, P=0.26). CONCLUSION: CETP inhibitors reduced the incidence of diabetes. The improvement in glucose metabolism may have been related, at least in part, to the increase in HDL-C concentration.
