[The modification of method of erythrograms in patients under chronic hemodyalisis using hardware-controlled administration of laser low-angle light scattering].

The detailed analysis of structural characteristics of erythrocytes can be implemented with method of erythrograms. However its practical application in conditions of medical laboratory is a long and labor-intensive process of little avail for express-diagnostic. To register alterations of morphologic functional characteristics of erythrocytes in patients under chronic dialysis as compared with patients without renal pathology the new technique of low-angle light scattering never applied before for this purpose. Therefore, the purpose of this study is to resolve issue concerning validity of application of this technique for registration of alterations of functional status of erythrocytes in patients of department of chronic dialysis as compared with patients without renal pathology. The experiments concerning the identification of resistance of erythrocytes established significant differences for acid and ammonium models of lysis between patients without renal pathology and patients under chronic dialysis and also in patients in the course of dialysis session. In case of ammonium lysis, the differences were statistically significant between patients without renal pathology and patients under chronic hemodyalisis. In case of acid model, the differences were statistically significant in patients in course of dialysis session. Therefore, the application of low-angle light scattering technique is valid and informative for evaluation of functional status of erythrocytes in patients with terminal stage of chronic renal disease receiving treatment of regular hemodyalisis. The technique itself is low-cost, simple in application and easily reproduced. Therefore, the technique of low-angle light scattering can be applied both in research studies and clinical practice to identify characteristics of stability of membrane systems.

[Clinical and laboratory evaluation of the efficiency of chronic hemodialysis treatment using acidosuccinate in patients with terminal renal failure].

AIM: To evaluate the efficiency of using a succinate-containing dialysis solution (SCDS) in terminal renal failure patients treated with chronic hemodialysis (CHD). SUBJECTS AND METHODS: Ninety patients from two hemodialysis units took part in the crossover study and were allocated to 2 groups. For 6 months, study group patients received CHD using SCDS and control group patients had CHD with a standard bicarbonate dialysis solution after 3-month washout period followed by decussation. The time course of changes in blood biochemical parameters, 24-hour ECG monitoring data, and quality of life indicators were estimated in the patients. RESULTS: After using acidosuccinate during hemodialysis, there was a significant reduction in the predialysis serum level of inorganic phosphate, a calcium phosphate product, gamma-glutamyl transpeptidase, urea, and aldosterone as compared to the control group. The blood concentration of total protein was also increased. After 6-month administration of acidosuccinate, the patients showed reductions in systolic blood pressure, heart rate, and the frequency and duration of ST-segment depression episodes. There were positive changes in the quality of life of patients according to the KDQOL-SF questionnaire. CONCLUSION: The use of SCDS in patients with CHD causes positive changes in a number of laboratory parameters and improves the physical and general status, and quality of life of patients.
