Chronic renal failure (CRF) is a complex clinical entity caused by progressive destruction of functional renal parenchyma in the course of various pathological processes resulting in complete failure of renal function and subsequent metabolic, acid base and electrolyte as well as immune disorders. Renal transplantation (RT) is one of the renal replacement therapy options in the terminal stage of chronic renal failure. The replacement of the failing organ with one from a healthy donor may be complicated with immune host response. This study was designed to investigate the changes in serum concentration of integrins CD11a/CD18, CD11b/CD18, CD69 on the surface of human polymorphonuclear leukocytes (PMNL) after the RT within two six-month periods. The study included 25 RT patients (mean 5.4±2.7 yrs after the transplantation, 10 females and 15 males) treated with immune suppressive therapy including cyclosporine A, azathioprine and prednisolone. The expression was assessed with monoclonal antibodies by means of flow cytometry. Also, the expression of CD69 was determined before and after phytohemaglutinine (PHA) stimulation. There was no significant alternation in serum concentration of CD11a/CD18, CD11b/CD18 and CD69 at baseline, six months and twelve months later. The expression of integrins was not altered in renal transplantation patients in the current study setting.

The recent clinical data indicate that the initial and the early stages of chronic renal failure (CRF) may lead to increased incidence of cardiovascular complications and increased extent of coronary artery disease (CAD). This retrospective study was aimed to determine the effects of coexisting diabetes mellitus type 2 (DM-2) and the extent of atherosclerosis in coronary vessels in patients with mildly reduced kidney function (glomerular filtration rate GFR = 89–60 ml/min) and moderately reduced kidney function (GFR = 59–30 ml/min). The study patients included 53 subjects with creatinine concentration above 120 μmol/l as a cut-off level for the initial stage and compensated CRF. The distributions of coronary artery stenosis were also analysed with respect to DM-2 coexistence and levels of haemoglobin glikolised (HbA1c). The odds ratio of pathological changes in coronary arteries in patients with GFR = 44–30 ml/min, with respect to the number of affected vessels - only one, more than one or more than two - were 7.22, 4.90 and 3.55, respectively. In CRF patients with GFR = 60–89 ml/min the odds ratio of one, more than one and more than two vessels with stenosis and CAD was 1.93, 1.70 and 1.53, respectively. DM-2 was not related to the risk of significant coronary artery stenosis and did not enhance the pre-existing changes in the study setting. Our results demonstrate that the initial and the early stages of CRF were significant risk factors for coronary stenoses and for enhancing the pre-existing changes.

Cytokines regulate the immune reactions elicited by renal transplantation (RT). This study was designed to investigate the blood serum levels of IL-2, IL-6, IL-8 in 25 RT patients (10 female and 15 male, mean 5.4±2.7 yrs after RT) three times over a six-month period during standard immunosuppressive therapy with cyclosporine A, azathioprine and prednisolone. The levels of IL-2, IL-6 and IL-8 were tested with ELISA Quantikine Human Interleukin Immunoassay (R&D Systems, detection level 7,0.7 and 10 pg/cm3, respectively). There was no significant alternation of blood serum levels of IL-2, IL-6 and IL-8 in the study patients.
