Association of Apo(a)isoform size with dyslipoproteinemia in male venous thrombosis patients. | LitMetric

AI Article Synopsis

  • Lp(a) is a lipoprotein linked to the risk of venous thromboembolic disease (VTE), and the study investigates how different sizes of its component, apo(a), affect this risk.
  • Researchers analyzed apo(a) isoform sizes and Lp(a) concentrations in 46 VTE patients and 46 healthy controls, finding that VTE patients had a higher prevalence of medium-sized apo(a) isoforms.
  • The study suggests that higher Lp(a) concentrations in patients with larger apo(a) isoforms indicate a potential new marker for assessing VTE risk, highlighting the importance of understanding apo(a) characteristics.

Article Abstract

Background: Lp(a) is a proatherogenic lipoprotein that may also be prothrombotic. Apo(a) size isoforms have differential effects on fibrinolysis. Whereas Lp(a) concentrations have been linked to venous thromboembolic disease (VTE) risk, apo(a) polymorphisms in VTE have not been studied.

Methods: We used a standardized high resolution agarose gel electrophoresis technique to determine apo(a) isoform size, and a Lp(a) immunoassay insensitive to apo(a) size to measure Lp(a) concentration in 46 men with VTE and 46 age-matched healthy controls.

Results: Apo(a) isoform distribution in VTE cases and controls was bimodal and VTE patients tended to have more medium-sized isoforms K(4)-(19-27) (54.3% vs. 34.8%, p=0.06). Cases and controls had the same median predominant apo(a) size isoform (23.5 K(4) repeats) and comparable Lp(a) concentrations. However, subgroup analysis based on apo(a) isoform size (K(4)< or =23 or K(4)> or =24) revealed that cases in the K(4)> or =24 subgroup had higher Lp(a) concentrations than the controls in this isofrom subgroup (14.5 mmol vs. 6.6 mmol, p=0.029). Also, dyslipoproteinemia (smaller LDL and HDL particles, higher LDL and lower HDL parameters) was strongly associated with VTE only in this larger apo(a) isoform group.

Conclusions: These observations provide the first evidence that determination of apo(a) isoforms may provide useful novel insights into VTE risk.
