ABSTRACT
The 4G/5G polymorphism of the plasminogen activator inhibitor type 1 (PAI-1) affects the plasmatic concentration of the protein. Besides, in vitro studies demonstrated that triglycerides, very low density lipoproteins-cholesterol (VLDL-c), insulin and glucose increase the gene expression.
Objective: To analyze the genetic and allele frequency of the 4G/5G polymorphism of the PAI-1 and its association with the lipid profile in patients with rheumatoid arthritis (RA), osteoarthritis (OA) and clinical healthy controls (HC).
Material and methods: Cross-sectional study. The 4G/5G polymorphism of PAI-1, was analyzed for PCR-RFLP’s (polymerase chain reaction- restriction fragment length polymorphisms) using the restriction enzyme Bsl I. The statistical analysis fulfilled with the SPSS 10.0 and Epi Info 2000.
Results: The population studied was in Hardy-Weinberg’s balance. The frequency of the genotypes 5G/5G, 4G/5G, 4G/4G in RA was: 44.1%, 52.9% and 2.9%; in OA: 32.2%, 54.8% and 12.9% and in HC: 35.1%, 51.4% and 13.5%, respectively. The HC with genotype 5G/5G presented increase levels of triglycerides, total cholesterol and VLDL-c (p ‹ 0.05).
Conclusions: The genotype 5G/5G is associated with increase of triglycerides, total cholesterol and VLDL-c in HC.
