Treatment with PCSK9 inhibitors induces a more anti-atherogenic HDL lipid profile in patients at high cardiovascular risk.

Background: Proprotein Convertase Subtilisin/Kexin type 9 inhibitors (PCSK9-I) have been reported to cause a moderate increase in high-density lipoprotein (HDL) cholesterol in human studies. We thus evaluated the effect of two approved PCSK9-I on the concentration and lipid composition of HDL particle subclasses.

Subjects And Methods: 95 patients (62.

A reference measurement of circulating ATPase inhibitory factor 1 (IF1) in humans by LC-MS/MS: Comparison with conventional ELISA.

ATPase inhibitory factor 1 (IF1) is a 9.5 kDa protein that binds to mitochondrial and plasma membrane ATP synthase and selectively inhibits ATP hydrolysis. Recently, IF1 was identified in systemic circulation in humans.

Serum level of HDL particles are independently associated with long-term prognosis in patients with coronary artery disease: The GENES study.

HDL-Cholesterol (HDL-C) is not an accurate surrogate marker to measure the cardioprotective functions of HDL in coronary artery diseases (CAD) patients. Hence, measurement of other HDL-related parameters may have prognostic superiority over HDL-C. In this work, we examined the predictive value of HDL particles profile for long-term mortality in CAD patients and to compare its informative value to that of HDL-C and apoA-I.

Impact of micronutrient deficiency & malnutrition in systemic sclerosis: Cohort study and literature review.

Objectives: The purpose of our study was to determine the prevalence and risk factors associated with malnutrition, and selenium (Se) and vitamin C (vitC) deficiencies in systemic sclerosis (SSc) patients.

Methods: We included adult SSc patients fulfilling the 2013 ACR/EULAR criteria from the Toulouse University Hospital cohort who underwent a micronutrient workup (including vitC, Se or thiamine levels) between 2011 and 2016.

Results: 82 patients were included, mostly women (76%), with a median age of 60 years.
