Organ and Tissue Procurement From Non-residents Deceased in Poland: Guidelines for Transplant Coordinators.

Due to increasing global mobility, the number of non-residents who are potential deceased organ donors is likely to increase as well. Since 2014, 14 deceased foreigners have been referred as potential organ donors in Poland. There are, however, no precise international agreements between Poland and other countries regulating this issue. The aim of this paper is to provide guidelines on this subject for transplant coordinators. While there are no differences in the algorithms of potential donor identification, death diagnosis, donor management, organ procurement and preservation, allocation, transportation and transplantation, and the medical evaluation of a foreigner as a potential organ donor may differ. In certain cases, the risk of tropical or endemic infections should be evaluated. The authorization of the procurement may differ as well-foreigners who are not listed in the Polish Electronic System for Registration of Population cannot be registered in Polish Central Registry of Objection. They may have also not expressed refusal or consent for donation due to different legal solutions in their home countries. The donor's family and the proper diplomatic representative must be involved in donation process in order to obtain authorization for organ donation, to acquire essential medical information about the donor, and to ensure the transparency of the process. The procurement of organs, tissues and cells from foreigners deceased in Poland may be performed provided that a proper donor qualification process is conducted, the deceased had not objected to donation, there is no objection on the part of the donor's family or the prosecutor (if required), and the donation and procurement are properly described in medical documentation.

Paired Analysis of Outcomes After Kidney Transplantation in Peritoneal and Hemodialysis Patients.

BACKGROUND: The impact of dialysis modality before kidney transplantation (hemodialysis or peritoneal dialysis) on outcomes is not clear. In this study we retrospectively analyzed the impact of dialysis modality on posttransplant follow-up. METHODS: To minimize donor bias, a paired kidney analysis was applied. One hundred thirty-three pairs of peritoneal dialysis (PD) and hemodialysis (HD) patients were transplanted at our center between 1994 and 2016. Those who received kidneys from the same donor were included in the study. HD patients were significantly older (44 vs 48 years), but the Charlson Comorbidity Index was similar (3.12 vs 3.46) in both groups. The groups did not differ significantly with respect to immunosuppressive protocols and number of mismatches (2.96 vs 2.95). RESULTS: One-year patient (98% vs 96%) and graft (90% vs 93%) survival was similar in the PD and HD patient groups. The Kaplan-Meier curves of the patients and graft survival did not differ significantly. Delayed graft function (DGF) and acute rejection (AR) occurred significantly more often in the HD recipients. Graft vessel thrombosis resulting in graft loss occurred in 9 PD (6.7%) and 4 HD (3%) patients (P > .05). Serum creatinine concentration and estimated glomerular filtration rate (using the Modification of Diet in Renal Disease guidelines) showed no difference at 1 month, 1 year, and at final visit. On multivariate analysis, factors significantly associated with graft loss were graft vessel thrombosis, DGF, and graft function 1 month after transplantation. On univariate analysis, age, coronary heart disease, and graft loss were associated with death. Among these factors, only coronary heart disease (model 1) and graft loss were significant predictors of death on multivariate analysis. CONCLUSION: The long-term outcome for renal transplantation is similar in patients with PD and HD. These groups differ in some aspects, however, such as susceptibility to vascular thrombosis in PD patients, and to DGF and AR in HD patients.

System of Monitoring Potential Deceased Organ Donations in Over 200 Hospitals in Poland Using a Web Tool: Implementation and Structure.

BACKGROUND: In 2010 the formation of the Polish Hospitals Network of Organ Donation Coordinators, originated by Poltransplant, began. One of the goals of this project is to report all deaths in hospital ICUs in which a coordinator is posted. The aim of this strategy is to monitor donation potential, following the recruitment process of potential donors and indicating stages of that process that may be improved to increase effective recruitment. Until the end of 2014 all data were forwarded to Poltransplant as Excel files, but since January 1, 2015, reporting and data collection have been are performed using web tool www.koordynator.net. AIMS: The aim of the paper is to present the essentials in functioning principles, structure, and usage of the www.koordynator.net system, its technical construction, and to display good practices (know-how) tested by 1 country, for countries such as Poland, that contend with organ insufficiency. METHODS: The application www.koordynator.net allows for remote addition of individual records with information about deceased patients in hospital ICUs, the forwarding of data about potential and actual organ donors, the generation of complete reports about deceased patients in each hospital monthly, and the introduction of historical data. SUMMARY: Introduction of a potential donation monitoring system in 209 hospitals with transplant coordinators increases the number of identified potential and effective actual donors due to self-assessment analysis. Eventually, the www.koordynator.net reporting system allowed for external evaluation by coordinators from other hospitals, regional coordinators, and Poltransplant. The system is a modern tool that improves and increases the quality system in the organ donation field (quality assurance program).

Evolution of Organ Transplantation in Poland 1966 to 2014: Dates and Numbers.

BACKGROUND: Several events inspired us to collect data on organ transplantation in Poland (2016: the 50th anniversary of the first transplantation and the 20th anniversary of Polish Transplant Coordinating Center Poltransplant). The paper aims at presenting comprehensive data on all organ transplants, beginning with the first in 1966 (deceased kidney) until the end of 2014. METHODS: Source documents were reports published in Poltransplant Bulletin, a website registry managed by Poltransplant, reports by the Transplantation Council and by the Transplantation Institute of Warsaw. A source data enabled us to establish a preliminary report, presented for verification during the 12th Congress of the Polish Transplantation Society. RESULTS: By the end of 2014, the total number of organ transplants was 26,691. Kidney transplantation is the most common (total number = 19,812). The number of living kidney transplants is low, about 50 per year. The number of liver part transplants from living donors is relatively high, 20 to 30 annually. The program of deceased liver transplantation results in more than 300 transplants yearly. The first heart transplantation was in 1985, but the number of these procedures has been decreasing. No significant increase in the number of lung transplantations was noted. CONCLUSIONS: The number of organ transplantations from deceased donors places Poland in the middle among European countries. The number of living donor kidney transplants is lower than in other countries; therefore a living donor liver transplantation program belongs to leading programs. Progress of lung transplantation has been slow. The development is highlighted by vascularized composite tissue transplantations of the hands and face. The strength of the report lies in its reliability and completeness. Numbers are the unique source of information to be used and referred to in the literature.

Candida arteritis in kidney transplant recipients: case report and review of the literature.

Multi-organ procurement is a risk factor for contamination of preservation fluid with intestinal flora including fungi (e.g., Candida). Transmission of fungal species to the graft vessel can cause mycotic arteritis. This is a very rare but life-threatening complication of renal transplantation. We present 2 cases of renal transplant recipients from the same multi-organ donor. Both recipients suffered from severe hemorrhages from renal graft anastomosis and renal artery pseudoaneurysm due to Candida albicans arteritis (CAA). The culture of the preservation fluid revealed growth of Escherichia coli, but neither preservation fluid nor multiple routine blood cultures performed before hemorrhagic complications revealed fungal growth (media non-selective for fungal growth were applied). The first recipient suffered from sudden severe hemorrhage in the area of graft anastomosis on day 10 post surgery (without any preceding clinical or radiological symptoms). This led to urgent surgery and graftectomy, which was complicated by cardio-respiratory arrest with resuscitation in the operating room; despite resuscitation, irreversible brain damage, and subsequent death occurred in the intensive care unit (ICU) 2 weeks later (on day 24 after transplantation). The second patient underwent urgent vascular surgery on day 22 (after transplantation), because of hemorrhage from a pseudoaneurysm of the graft artery. She required repeated vascular operations, extended antimicrobial and antifungal therapy, and ICU monitoring and, despite these interventions, she died on day 80 after transplantation as a result of Pseudomonas aeruginosa sepsis. Arteritis of the renal artery in both patients was caused by C. albicans. This was confirmed by histopathology: infiltration of renal artery with budding yeast forming pseudohyphae (Case 1), and the presence of C. albicans in the culture of the renal artery and surrounding tissue (Case 2). We conclude that organ preservation solution should be cultured with use of media selective for fungal growth. As soon as the positive culture is detected, appropriate measures protecting patients against CAA should be undertaken.

Preemptive kidney transplantation: analysis of kidney grafts from the same donor.

BACKGROUND: From November 2003 to December 2012, in the Gdansk Center, 64 patients received preemptive transplantation (PET). PET comprised 8% of 794 kidney transplantations performed during this time. The benefits for individual patients and for the health care system are discussed. METHODS: This study compares the outcomes of these PET patients who had their kidney pairs transplanted after a variable duration of dialysis (PTD), a total of 51 pairs. RESULTS: The mean Charlson comorbidity index was 2.57 vs 3.04 (P > .05) for the PET and PTD groups, respectively. Both groups did not differ significantly with respect to 1-year patient and graft survivals, and incidences of acute rejection. Five (9.8%) PET patients and 20 (39%) PTD patients experienced delayed graft function (P < .05). The graft function (serum creatinine/4p MDRD) 1 year after transplantation was similar in both groups (1.42/53.7 vs 1.43/57.4; mg/dL/mL/min/1.73 m(2)). More PET patients continued normal professional activities or education before and after transplantation (P < .05). CONCLUSIONS: Our single-center results confirmed that for both medical and socioeconomic reasons, PET is an optimal mode of renal replacement therapy.

Educational system for transplant coordinators in Poland: postgraduate studies at Warsaw Medical University; 2 years of experience.

Donor hospital transplant coordinators play crucial roles in the donation process. There are only a few coordinators in Poland, while there are about 400 hospitals with intensive care units (ICU). Coordinators must be professionals in medical sciences, clinical psychology, law, organization, management, and statistics. Coordinators acquire these skills during the Transplant Coordinators Postgraduate Studies at Warsaw Medical University which began in 2007. Lectures, seminars and exercises (99 hours, 6 weekends) are run by experts. The studies end with an examination and a diploma. The main criterion for acceptance of a candidate is employment in a key department in the donation process. The aim of studies is to educate coordinators for each hospital in the country. Until now 4 editions of the course have been completed. Among 123 graduates, 71 (60%) are employed in strategic departments of 48 hospitals. Preliminary results of graduates' activities in donor detection were compared in the periods before (2005-2006) and after the course (2007-2008). The background was the overall activity in Poland, where in 2007-2008 the activity fell to 79% of 2005-2006. This fall for hospitals with the graduates of this program was 82% versus hospitals without them (76%). Of the 48 hospitals that employed the graduates: 14 improved donation 5 were the same, in 12 in both periods showed no donations; whereas in 11 it was much lower (>20%), and in 6 lower but consistent with the national trend.

Renal transplantation in dialysis patients with the history of coronary artery bypass grafting and cardiac valve replacement.

Death with a functioning kidney is the most frequent cause of graft failure. Cardiovascular disease is the most frequent cause of death after renal transplantation. Therefore, prior to grafting, it is mandatory to diagnose and treat coronary artery disease and heart valve impairment. Transplantation is the best option for renal replacement therapy as far as the quality of life and life expectancy are concerned, although patients with such comorbidities may experience a higher short-term mortality risk. The objective for this study was to analyze both short- and long-term results of patients after coronary artery bypass grafting (CABG) or cardiac valve replacement (CVR). The cardiac surgery recipient group (CSR) included 16 patients (15 men, 1 woman) aged from 44 to 73 (mean 54.9 +/- 7.8) years. CABG was performed in 13/16 patients, and CVR in 3/16. The rest of our patients were treated as a comparative noncardiac surgery recipient (non-CSR) group. It consisted of 422 patients (264 men, 158 women) aged from 14 to 68 years (mean 43.2 +/- 12.9). The comparison revealed that graft function estimated at 1 year after transplantation was not different: serum creatinine concentrations of 1.7 +/- 0.2 and 1.6 +/- 0.5 mg/dL in CSR and non-CSR, respectively. One-year patient survival in the CVR group of 93.8% was slightly worse than that in the non-CSR group (97.9%), but death-censored 1-year graft survivals were comparable in both groups (93.8% vs 92%). Urinary tract and cytomegalovirus infections were the most common complications in the CSR group. One patient lost his graft in month 3(rd) due to many serious infectious complications. One patient died at the end of 12 months as a result of a cardiovascular event (1/16). Our single-center results confirm that transplantation in patients after CABG or CVR is a safe procedure; therefore, such patients should be referred into the waiting list.

A single center experience in preemptive kidney transplantation.

Transplantation is recognized as preemptive if it takes place before the initiation of chronic dialysis. This maneuver has the potential to avoid the morbidity and burden of chronic dialysis. From November 2003 to April 2005, 15 (7 male, 8 female) end-stage renal failure patients of mean age 40 +/- 14.8 years received preemptive grafts from 2 living-related and 13 cadaveric donors, constituting 11.5% of all kidney transplantations performed in our center at that time. The period on the waiting list for preemptive recipients, namely, 2 weeks to 6 months (mean, 2.4 months), was significantly shorter than that of other patients (mean, 13.8 months). The mean creatinine clearance calculated from the Cockroft Gault formula and the mean plasma creatinine level in preemptive recipients before transplantation were 12.7 +/- 3.1 mL/min and 6.6 +/- 0.8 mg/dL, respectively. The donors for preemptive and non-preemptive groups of recipients did not differ significantly in respect to age, gender, and renal function. The mean number of mismatches of 3.73 and 3.25 and the mean total ischemic times of 9.53 +/- 5 and 11.2 +/- 5 hours, in preemptive and non-preemptive groups of recipients, respectively. The incidence of delayed graft function (dialysis in the first week after transplantation) was significantly lower among preemptive recipients (20% versus 42%, respectively). The groups did not differ either in respect to the occurrence of acute rejection episodes or graft and patient survivals. In preemptive patients the mean plasma creatinine levels at 3 and 12 months were 1.37 +/- 0.3 and 1.09 +/- 0.3 mg/dL, and in non-preemptive patients 1.7 +/- 0.5 and 1.4 +/- 0.4 mg/dL. In conclusion, these results are promising, confirming the notion that preemptive kidney transplantation is the optimal treatment for end-stage renal disease patients.
