Paper Abstract

The development of robust non-invasive laboratory screening methods for early diagnosis on the out-patient basis seems quite relevant for practical medicine. It is known, that platelet is an original biosensor, a detector of early changes in hemostasis condition. The aim of this study was to assess a potential of the quantitative phase imaging (QPI) technique for real time evaluation the influence of low-molecular weight and unfractionated heparin on platelets in patients with the end-stage of chronic renal failure, who were treated with program hemodialysis (PHD).

The main group consisted of 21 patients who were administered a low-molecular weight heparin for hypocoagulation during the procedure of hemodialysis. The control group (15 patients) received unfractionated heparin. Morphodensitometric state of living platelets we evaluated by QPI using computer phase-interference microscope MIM (Moscow, Russia). We analyzed the optical–geometrical parameters and the morphological features of living platelets which reflected the degree of their activation at the beginning of PHD (before administration of heparin), in 15 minutes after it and at the end of the procedure. The results allow us to conclude that the use of low-molecular weight heparin provides better ratio of efficacy/safety and causes a reduction of the platelet activation during the hemodialysis procedure. Practical implementation of QPI for clinical monitoring of platelets makes it possible to obtain important information on hemostasis cell. It opens new opportunities to assess the efficacy of treatment, as well as for early diagnosis of complications for disease.
