title: [Plasma fibrinopeptide A, fibrinopeptide B beta 15-42 and 4 other coagulation factors levels in patients with diabetic retinopathy].
abstract: Fibrinopeptide A (FPA), fibrinopeptide B beta 15-42 (FPB beta 15-42) and other coagulation factors (anti-thrombin III, thrombin-antithrombin complex, alpha 2-macroglobulin, plasmin inhibitor complex) were measured in the plasma of 101 patients with diabetes mellitus (DM). The levels in 80 healthy adults were also measured for comparative purposes. The mean levels of FPA, FPB beta 15-42 and the other 4 coagulation factors in the DM patients were significantly higher than in the controls (p < 0.05). The mean levels of FPA and FPB beta 15-42 in patients with diabetic retinopathy (DR) were higher than in those without DR, that is in those with proliferative diabetic retinopathy (PDR) higher than in those with simple diabetic retinopathy (SDR). In patients after panretinal photocoagulation (PRP), the mean level of FPA was higher and that of FPB beta 15-42 was lower than in patients before PRP. In the SDR group, the level of FPB beta 15-42 was significantly correlated with the progression of diabetic retinopathy. We suggest that there was a close correlation between plasma FPA and FPB beta 15-42 levels and activity or progression of disease, and that the investigation of these levels may be useful for the judging of prognosis or effect of therapies of diabetic retinopathy.
