The comparison of results obtained for the investigated suture materials after suturing oral mucosa revealed that certain advantage could be given to synthetic monofilament suture materials.

In regard to physical health of transplantation patients (TP) it was established that work capacity and activities were less damaged, whereas physical activity was highest in pts on CT. Social activity was limited in a higher percentage in TP (40%) than in hemodialysis patients (HD) (19%), while family relationships were most damaged in pts on HD (28.57%). Discomforts were most common in pts on HD. The highest percentage of pts estimated their health status as good or average, but their health status improved after transplantation in 82.86% that is in 57.14% after HD. It was similar with the quality of life: 28.57% of kidney transplant patients rated their quality of life as very good, and 54.28% rated it as good: 38.09% of HD patients rated their quality of life as very good, whereas only 5% of CT patients rated it as very good, and 20% as good.

Peritoneal dialysis is the method of treatment of terminal-stage chronic kidney failure. Nowadays, this method is complementary to haemodialysis. It is based on the principles of the diffusion of solutes and ultrafiltration of fluids across the peritoneal membrane, which acts as a filter. The dialysate is introduced into the peritoneum via the previously positioned peritoneal catheter. The peritoneal dialysis is carried out on daily basis, at home by the patient, and the "exchange" is repeated 4-5 times during the 24 hours. The first steps in peritoneal dialysis at the Department for Haemodialysis of the Clinical Centre of Vojvodina date back to 1973. Until 1992, the patients were subjected to this program only sporadically. Since 1998 the peritoneal dialysis method has been performed at the Clinic for Nephrology and Clinical Immunology. In the period 1998-2008 ninety nine peritoneal catheters were placed. Chronic glomerulonephritis, nephroangiosclerosis and diabetes were identified as the most common causes of chronic renal failure. Two methods of catheter placement were applied: the standard open surgery method (majority of patients) and laparoscopy. Most of the patients were subjected to continuous ambulatory peritoneal dialysis, whereas four patients received automatic dialysis. Transplantation was performed in 10 patients, i.e. cadaveric transplantation and living-related donor transplantation, each in 5 patients. Peritoneal dialysis was available as a service outside our institution as well. A ten-year experience in peritoneal dialysis gained at our Centre has proved the advantages and qualities of this method, strongly supporting its wider application in the treatment of terminal-stage chronic kidney failure.

In this study we found severe histopathological changes in the group with already impaired renal function and these changes correlated with laboratory findings, clinical features and prognosis. Normal renal function at the moment of renal biopsy pointed to risk for further damage. Changes in the tubulointerstitium and mesangium, heavy proteinuria and hypertension affect the disease prognosis. Evolution to the higher stage of renal failure was 1.24% per year and this requires long-term follow-up of patients with IgAN.

Mycophenolate mofetil has satisfactory results in the treatment of proliferative forms of lupus nephritis with minimal side effects.
