[Lipoprotein and plasminogen serum levels in patients with diabetes mellitus type 2: risk factors for macroangiopathy? Preliminary study].
Lipoprotein(a) [Lp(a)] is the specific lipoprotein which physiological role has not been explained. Similarity between apolipoprotein(a) and plasminogen structure suggests, that Lp(a) can be the bridge connecting the lipid metabolism and the coagulation system. The aim of the study was to evaluate if there is any correlation between Lp(a) and plasminogen serum concentrations in patients with diabetes t.2. 20 males and females with diabetes t.2 in the age 19-75 years (mean: 54.9 years). The control group consisted of 15 healthy men and woman in the age of 23 years (medical students). Lp(a) was estimated by ELISA, plasminogen by turbidimetric methods. Lp(a) serum level in the examined group was: 40.06 + 59.45 mg%. In 7 patients it was over 30 mg%. In the control group: Lp(a) concentration was: 13.23 + 10.5 mg%, no one was above 30 mg%. The different was significant. Plasminogen concentration was: in patients: 94.08 + 53.08%, in the control group: 89.08 + 40.7%. There was no significant difference. Correlation index between Lp(a) and plasminogen concentrations was in the patient's group: 0.3, in the control group: 0.2. In patients with diabetes we can find increased Lp(a) commentation in serum and normal plasminogen concentration. Concentration of Lp(a) didn't demonstrate significant correlation with plasminogen serum level.
