Association between polymorphisms in the fibrinogen α- and β-genes on the post-trauma fibrinogen increase
article
Fibrinogen is an acute phase reactant, and there, fore its plasma levels increase after severe injury. Polymorphisms in the fibrinogen α and β genes have been found to be associated with plasma levels of fibrinogen, and it has also been suggested that they are associated with the fibrinogen increase in acute phase situations. In forty-five consecutive patients admitted to the Intensive Care Unit after acute cranial or thoracic trauma, we investigated the influence of four polymorphisms at the fibrinogen loci (-455G/A and BclI (β gene), TaqI and T/A312 (α gene)) on the post-trauma increase of the fibrinogen levels. At admission, fibrinogen levels were comparable in the patients with the different genotypes for the four polymorphisms studied. However, patients carrying the -455A allele of the -455G/A polymorphism had a significantly wider variation and higher peak levels of fibrinogen, during their stay at the intensive care unit, than did the -455GA homozygotes (5.1 g/I (SD 1.3) and 5.9 g/1 (SD 1.0), respectively, p<0.05). Such difference was not found for the other studied polymorphisms. The present study suggests that the increase of fibrinogen level in acute phase situations like severe trauma is associated with the β-gene -455G/A polymorphism.
