BK-polyomavirus infection in patients after simultaneous pancreas and kidney transplantation
Mindlová, Martina ; Saudek, František (advisor) ; Forstová, Jitka (referee) ; Reischig, Tomáš (referee)
Introduction. The aim of the study was to introduce a new BKV PCR protocol in our centre and to verify its accuracy as well as to assess the prevalence, risk factors of BK virus replication, course of BKV infection and therapeutic approaches in simultaneous pancreas and kidney (SPK) recipients in order to design a screening protocol. Methods. The results analysed by both Affigene® and Transplantation Virology, Basel PCR protocols were compared. Thereafter 183 SPK patients were examined to assess the prevalence of BK viremia, viruria and BKVN and to identify the risk factors of BKV replication. The cases of retransplantation after a graft loss due to BKVN were retrospectively described. Results. 100 of results were analysed according to the Affigene ® and Transplantation Virology, Basel PCR protocols with the accordance of 95%, Rho = 0,946, 95% CI: 0.920 - 0.963, P<0,0001, Bland-Altman plot analyses: bias Basel PCR protocol/Affigene® BKV trender: -0,1 (mean) *±1.96 SD: -1,6 - 1,3] for both methods. Point-prevalence was assessed in 183 patients; Viruria found in 17,3 %, viremia in 3.8% of patients. High-level viruria >107 copies/mL detected in 3,7% of patiets, high-level virémia >104 in 1,6% of patients simultaneously with high-level viruria. BKVN was found in 0,5% of patients.

Analysis of BK virus life cycle
Bakardjieva - Mihaylova, Violeta ; Drda Morávková, Alena (advisor) ; Mindlová, Martina (referee)
Polyomaviruses are small unenvelope DNA viruses, whose replication take place in cell nucleus. Despite its small genome size, these viruses can cause significant changes in the host cell, one of the most significant is cell transformation. Most studies of human pathogens from this family is the focus of clinical research, but do not provide enough information about the individual events of the life cycle of viruses. This thesis mainly aims to determining the exact time when the creation of the individual viral products and generate a timeline of events during natural infection in cells that are targets for BKV in the human body. It was found that the time course of the life cycle of BKV is very similar to those for model polyomaviruses MPyV and SV40 and in permissive cells takes about 40 - 50 hours.
