A Specialist in Nephrology Has Become an Associate Professor at MU - Varna

On 2nd July, the academic title of "Associate Professor" of Nephrology Science Specialty was awarded to Dr. Rositsa Yordanova Zorcheva-Vateva, MD, PhD by the Academic Council of MU- Varna.

Assoc. Prof. Dr. Rositsa  Zorcheva-Vateva , MD, PhD presented her monograph "Peritoneal Dialysis in Renal Replacement Therapy - Modern Clinical Strategy" - the first comprehensive and systematic publication on this treatment method in the Bulgarian nephrological literature.
An essential part of the research of Assoc. Prof. Vateva is related to Peritoneal Dialysis, the significance of residual renal function in this kidney substitution method, as well as the length of life of patients with this type of dialysis. Based on recommendations by the International Society of Peritoneal Dialysis (ISPD), Assoc. Prof. Vateva has developed her own strategy for prevention of peritonitis, suggesting an algorithm for prevention and therapeutic approach in these common complications of Peritoneal Dialysis. Moreover, she has provided recommendations for Peritoneal Dialysis in particularly vulnerable patient groups, such as the elderly and diabetics. Furthermore, she has proved the need for including assisted dialysis as a therapeutic strategy also as a form of medico-social support, which can be carried out at home by nurses.
Another part of the contributions of the scientific works of Assoc. Prof. Dr. Positsa Zorcheva, MD, PhD is related to the plasma thrombocytopoietic activity in patients with chronic renal failure (CRF), whereas the experimental part on animals is included, as well. Moreover, she has made a comprehensive analysis of the thrombocytopenia and its regulation in a CRF. In addition, she has analyzed large amounts of data from the world literature regarding the concepts of thrombocytopenia and the presence of dialysable substances in the plasma of patients with uraemia, which is inhibited. Besides she has analyzed data related to calcium - phosphorus disorders in patients with CRF, the importance of bone loss, renal osteodystrophy and osteoporosis, the onset of calcification in CRF, with an analysis of valvular calcification and calcification in the mammary glands.
She has conducted several studies related to Gerontonephrology, as well as research on the oxidative status and some options for influencing it in patients on hemodialysis. For the first time in the country she has reported data for the importance of on-line hemodiafiltration and its connection to the removal of phosphate and beta-2 microglobulin, acute phase proteins.
She has developed several issues on terminal renal insufficiency, such as histamine levels in uraemic pruritus, glycation end products in CRF, Peritoneal Dialysis and pregnancy.


* Peritoneal Dialysis (PD) is a method of treatment of terminal chronic renal failure (CRF), in which sterile, mostly glucose-saline solutions are infused into the peritoneal cavity through previously placed indwelling catheter. Through the vessel walls of the richly supplied with blood peritoneum, by diffusion and ultrafiltration the toxins from the blood of the patients pass into the infused dialysis solution and by removing it they are completely eliminated from the body.
