[The pathogenesis of abdominal aortic aneurysm and polymorphism of haptoglobin and inflammatory factor].

52 patients were operated on for abdominal aortic aneurysm and 38 for aortic occlusion disease. Haptoglobin (Hp) phenotypes were determined in all these patients. Hp and C-reactive protein (CRP) concentrations were determined in each phenotype. On the basis of the statistical analysis the highest percentage of elevated CRP concentrations was found in patients with abdominal aortic aneurysm and phenotype Hp 2-1.

[How quickly does an abdominal aortic aneurysm grow?].

86 patients with Abdominal Aortic Aneurysm was assessed by abdominal ultrasound with respect to growth rate. For aneurysms with diameter 3-4 cm, mean growth rate was 0.215 mm per month, for aneurysms 4-5 cm was 0.33 mm per month and for aneurysms with AP diameter bigger than 50 mm the mean growth rate was 0.78 mm per month.

Abdominal aortic aneurysm: association between haptoglobin phenotypes, elastase activity, and neutrophil count in the peripheral blood.

To investigate the role of genetic factors on susceptibility to atherosclerotic arterial disease, the influence of haptoglobin phenotypes (Hp) on serum elastase activity, neutrophil count, and elastin concentration in the aorta was measured in patients with abdominal aortic aneurysm (AAA; n=52) and aortoiliac atherosclerotic occlusive disease (AOD; n=37). Findings (serum elastase activity, peripheral blood neutrophil count) were compared to a control group (CG) of 37 subjects without atherosclerosis. Hp phenotyping performed by starch-gel electrophoresis produced a haptoglobin-hemoglobin complex of three phenotypes: Hp1-1, Hp2-2, and Hp2-1. Distribution of Hp phenotypes was similar in the three study groups (AAA, AOD, CG). Significant increases in serum elastase activity and neutrophil count was measured in Hp2-1 phenotype of AAA patients. Although the aorta wall of aneurysm patients contained less (p<0.001) elastin than that of AOD patients, no significant difference of aorta elastin concentration between the three Hp phenotypes, including Hp2-1, was measured. The postulated association of AAA susceptibility with Hp2-1 phenotype was supported by the study data that demonstrated an increase in serum elastase activity in patients undergoing AAA repair.
