High triglycerides and low high-density lipoprotein cholesterol lipid profile in rheumatoid arthritis: A potential link among inflammation, oxidative status, and dysfunctional high-density lipoprotein.

Background: The interactions between inflammation and lipid profile in rheumatoid arthritis (RA) are poorly understood. The lipid profile study in RA has been biased toward lipoprotein levels, whereas those of triglycerides (TGs) and lipoprotein functionality have been underestimated.

Objectives: Since recent findings suggest a role for TG and TG-rich lipoproteins (TRL) on inflammation, we aimed to evaluate a combined lipid profile characterized by high TG and low high-density lipoprotein cholesterol levels (TGHDL) in RA.

Antibodies to paraoxonase 1 are associated with oxidant status and endothelial activation in rheumatoid arthritis.

Traditional and non-traditional cardiovascular (CV) risk factors underlie CV disease occurrence in rheumatoid arthritis (RA). Recently, a functional impairment of high-density lipoprotein (HDL) has been observed. Although the actual players are unknown, anti-HDLs were associated with altered lipid profile, decreased paraoxonase 1 (PON1) activity and CV disease in RA.

Antibodies to high-density lipoproteins are associated with inflammation and cardiovascular disease in rheumatoid arthritis patients.

Several lines of evidence suggest that chronic inflammation and immune dysregulation are related to altered lipid profiles in rheumatoid arthritis (RA), but the actual mechanisms are still unclear. We wondered whether the development of antibodies against high-density lipoprotein (HDL) can be found in RA patients linked to clinical and cardiovascular (CV) risk factors. To this end, immunoglobulin G (IgG) anti-HDL antibodies and total IgG serum levels were quantified in 212 RA patients, 131 sex- and age-matched healthy controls (HC), and 52 subjects with traditional CV risk factors (tCVRs).

Auditing secondary prevention of ischaemic heart disease in rural areas of Spain: an opportunity for improvement.

Aim: To describe the standard of secondary prevention received by individuals with a history of ischaemic heart disease (IHD) in Spanish rural areas, and the factors associated with low standards of quality.

Methods: Medical audit of patients with a history of IHD, whose data were provided by 72 rural physicians in 12 autonomous regions (1030 cases). Quality criteria were used based on international guidelines.
