Quality System of Kidney Donation for Transplantation From Living Donors in Poland.

OBJECTIVE: The program aims to build and develop a high-quality donation system at the hospital and national level. Thirty coordinator posts for the transplantation of kidneys from living donors (LDs) were created. The coordinators' tasks were identified as determining or excluding the possibility of LD donation for kidney transplantation for every potential kidney recipient referred to the waiting list, qualifying potential LDs, supervising health monitoring for LDs and kidney recipients, and education and promotion of transplantation from LDs. METHODS: The coordinators' reports and verification of data in the national transplant register from June 1, 2018 to November 30, 2019 were analyzed. ETHICS: The study was conducted according to principles of the Declaration of Helsinki, and the Declaration of Istanbul participation was on a voluntary basis. RESULTS: Information on possible LDs was obtained from 707 (43%) of the 1630 potential recipients entered on the waiting list. In 373 cases there was no potential LD; 16 recipients did not give consent for kidney transplantation from a LD; for 318 recipients, 340 potential LDs were identified; 90 potential LDs were rejected at the initial stage for medical reasons; 60 potential donors were rejected at further stages of the qualification process; 3 persons resigned from donation; and 23 recipients were transplanted from deceased donors. Kidneys from 73 LDs were qualified and transplanted. On November 30, 2019, 91 potential donors were awaiting further qualification. As part of the program, 27 potential pairs for paired kidney exchange were reported to Poltransplant (17 pairs with positive HLA crossmatch, 10 with incompatible blood groups). CONCLUSIONS: The creation of posts for coordinators for LD kidney transplantation in centers that qualify for LD kidney transplantation enabled systematic monitoring of donation potential, which led to an increase in the number of LD kidney transplants in 2019. Making full use of donation potential should significantly increase these numbers in the coming years.

Transplant Coordinators' Opinions Regarding the Decreasing Indicator of Organ Donation From Deceased Donors in Poland.

Despite the good overall condition of Polish transplantation medicine there is a shortage of organs for transplantation. Health care is also in a stage of development with problems including insufficient funding and lack of personnel. In 2015 the number of deceased organ donors in Poland was 526, which was distinctly lower than in 2014 when it reached 594. The aim of this paper was to collect, elaborate on, and summarize the opinions of transplant coordinators regarding the decrease of donation indicators in Poland. MATERIALS AND METHODS: The opinions of the transplant coordinators were collected during training meetings and questionnaires performed in 2016. The questionnaires targeted coordinators of active hospitals (above 5 retrievals a year) and less active donor hospitals. RESULTS AND DISCUSSION: Transplant coordinators indicated a number of factors that influence donor hospital activity, such as changing roles of intensive care units, changes in hospital flow of patients in critical condition, lack of nurses and anesthesiologists resulting in work overload, changes in forms of doctors' employment, low basic income of health professionals, difficulties in determination of brain death, decrease in engagement of transplant centers in cooperation with donors' hospitals, inadequate in-hospital training meetings, undermining of authority of doctors and medical personnel, change of attitude towards transplantation medicine (treated as profitable, regular specialty), insufficient funding of hospitals and personnel for deceased donor recruitment, and disobeying the rules of personnel remuneration for their engagement in donation and retrieval. CONCLUSIONS: Analyzing the opinions of the coordinators, we can state the following: 1. support of the hospital or hospital unit management is crucial for effective donation programs, 2. there is a need to build and implement a hospital quality systems covering each stage of donor recruitment as well as hospital trainings, 3. there should be a transplant coordination team rather than a single coordinator, 4. transplantation centers should maintain good cooperation with donor hospitals, and 5. intensive care unit personnel identification with their own hospital, which is less likely in the case of "locum" employment, is one of the major factors supporting donation programs.

Relationships Between Social Attitudes Toward Deceased Organ Donation and the Donation Rates in Poland, a Country With an Opting-out System.

BACKGROUND: Monitoring of attitudes toward deceased donation gives the general view of the acceptance of this treatment but does not allow for precise prediction of single person's behavior. Consistency of actions and attitudes has many determinants, personal and situational. The idea of this study was to assess and compare relationships between behaviors and attitudes toward postmortem organ donation in single districts and between larger regions of the country (west and east). METHODS: Indicators calculated for the years 1996-2014 included the number of potential deceased donors (per million population [pmp]/y), the number of objections registered in the refusal registry (pmp), and the number and percentage of family refusals to donation. To assess relationships between variables, statistical and descriptive analyses were used. RESULTS: There were 10,731 potential donor referrals: 10 times more in the most active than in the least active province. Potential donor referrals from the western region were almost twice as high (18.3 pmp/y) as from the east (10.1). In 1,045 cases (9.7%), organs were not used owing to objections of the relatives; this index differed in each province up to 7-fold, but was almost the same in western and eastern regions. Total number of objections listed in the Refusal Registry was 28,725 (748 pmp). This index was different in each district up to 4-fold, but was not distinctly different in west and east regions. No distinct correlation (Pearson test) was found among the 3 assessed variables. CONCLUSIONS: Donation in Poland has much geographic differences. There is no common pattern of behavior and attitude toward donation and no correlation between these variables.

Central Register of Objections for Deceased Donation in Poland 1996 to 2014: The Country With an Opting-Out System.

BACKGROUND: Organ, tissue, and cell procurement from deceased donors for transplantation requires consent and authorization, documented donor's positive acceptance, or lack of objection to donation expressed while alive (consent). It also requires the fulfillment of other legal conditions required by law, such as person's legal abilities to act in this field or to obtain approval for donation (authorization). Consent to and authorization of donation from deceased donors requires regulations at the national level. Poland developed an opting-out policy with the Transplantation Act in 1996. The Central Register of Objections (CRO) was introduced on November 1, 1996. The purpose of this article is a formal analysis of all submitted objections and objection withdrawals managed by the CRO since the introduction of the registry in 1996 until the end of 2014. MATERIALS AND METHODS: All data collected by the CRO during 18 years of service was subject to analysis. The objections and withdrawals of objections are summarized in the tables, along with the age, sex, and place of residence of the registered residents. RESULTS: By December 31, 2014, a total of 29,288 records were registered, including 29,013 registered objections and 275 registered withdrawals of objections; this means that 0.075% of the country's population expressed objection to posthumous tissue and organ donation for transplantation. Legal representatives submitted 4208 declarations (15.6% of all declarations). The largest inflow of objections took place in 1997, the first full year of CRO activity. CONCLUSION: CRO is an indispensable option in a country with opt-out system as a part of organ donation authorization protocol. Number of registered objections is extremely low, in practice, this leads to a situation where the will of the deceased most often is obtained from his family.

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.

National Hematopoietic Stem Cells Transplant Registry in Poland: Nationwide Internet Reporting System and Results.

History of hematopoietic stem cell transplantations in Poland begins in early 1980s; the 1st bone marrow allotransplantation was performed in 1983 in the Central Clinical Hospital of the Military Medical Academy in Warsaw. Following years brought the 1st autologous stem cell transplantations. Ten years later, unrelated bone marrow transplantation was performed for the 1st time by the team of the Hematology and Blood and Marrow Transplantation Unit in Katowice. Since then, hematopoietic stem cell transplantation developed to be standard procedure and one of the most important therapies applied in leukemia treatment. The number of allotransplantations in Poland has grown significantly in the past 2 decades, which generated new needs and problems. In 2005, based on a new Transplant Law, a National Transplants Registry was created. Its main role is to collect data (registration of procedures and follow-up data) related to every transplantation case for stem cells and tissues as well as for organs. We present statistics concerning stem cell transplantations performed in Poland, as collected in the National Transplants Registry in the years 2006-2014. There are 18 centers transplanting hematopoietic stem cells in Poland. The total number of hematopoietic stem cell transplantations performed in 2006-2014 was 3,537, with allotransplantations from relatives accounted for 1,491 and from unrelated donors for 2,046. The main indication for allotransplantation in past years was acute leukemia.

Present data on organ donation and transplantation in Poland.

At present, organ transplantation activity in Poland is located in the middle among European Union countries. There are appropriate law regulations, well-organized legal structures, well-educated transplant teams, good transplantation results, and case registries. There are 24 organ transplant teams in 20 centers, including 46 programs. Since 1966, over 18,000 organs have been transplanted 14,300 kidneys; 1800 livers; 1700 hearts; 250 kidney/pancreases and 30 lungs. Every year almost 1500 organs are procured from about 500 cadaveric heart-beating donors (9-14 per million people [pmp]) with 50 from living donors: 800 to 1000 kidneys (21-28 pmp); over 200 livers (5-6 pmp); and 60 to 100 hearts (1.6-2.7 pmp). National transplant registries are maintained in Poltransplant including a central registry of refusals (the policy of presumed consent with registered objection on donation after death is implemented), waiting lists, a cadaveric and living donor registry, and a transplant registry. There are still some actions that should be undertaken to strengthen the transplantation system in Poland, to increase organ availability, to enhance the efficiency and accessibility of transplantation systems, and to improve quality and safety: namely, increasing deceased donations to their full potential, appointing transplant coordinators in every hospital where there is the potential for organ donation, promoting quality improvement programs, and promoting living donation.

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.

Viral hepatitis B and C markers in the population of deceased donors in Poland.

In the years 2001 to 2005 in Poland, 3146 potential deceased donors were referred with 2583 (82%) organs procured and 57 (2%) donors not used due to positive viral markers. According to Polish rules, in every case of possible organ harvest from a deceased donor we test viral markers of anti-HIV I/II, HBsAg, and anti-HCV. Organs from HBsAg-positive donors (the rule accepted in Poland a few years ago) are not transplanted; kidneys from anti-HCV(+) donors are transplanted into matched recipients. According to donor hospital capabilities, other viral tests are performed: anti-HBs, anti-HBc, HBeAg, and anti-HBe. We calculate the frequency of positive serological tests for viral markers among the population of deceased donors, for HBsAg it was 1.1% (from these donors 10 kidneys and 1 liver were transplanted); and for anti-HCV it was 2.6% (from these donors 78 kidneys were used). Anti-HBc-positive deceased donors, particularly liver donors (due to the high risk of viral transmission and de novo infection), are a major problem in transplantation, which reduced the number of used organs. Only 17 of 86 (20%) of the HBc-positive donors became liver donors compared with 257 of 524 (49%) donors from the HBc-negative group. But anti-HBc was checked only in 24% of potential donors (positive in 16.6% of cases), which means that 506 of 780 transplanted livers (65%) were obtained from donors of unknown anti-HBc status, 257 (33%) from anti-HBc-negative subjects and 17 (2%) from anti-HBc-positive subjects.

Organ donation in Poland 2006.

Organ transplantation program has been slowly developing over last 30 years. The number of DD (deceased donors) stabilized on the level of approximately 13/million of population. Multiorgan donation has been 45%, due to some problems with donor management. Polish Transplant Coordinating Center POLTRANSPLANT which is responsible for organization of procurement, organ allocation and providing several registries (registry of objections, registry of transplantation, waiting lists of potential organ recipients etc). National data on organ donation and transplantation are each year submitted to the Ministry of Health and the National Transplantation Council which is the Advisory Committee to the Minister.

Biliary complications following liver transplantation: single-center experience.

Biliary complications (BC) following orthotopic liver transplantation (OLT) remain one of the major causes of postoperative complications and treatment failures. The list of common BC consists of biliary stricture, fistula, ischemic type biliary lesions (ITBL), cholangitis, and bile leakage following T-drain removal. Between July 2000 and December 2004, 101 consecutive cadaveric OLTs were performed in our institution. All but three were first full-size grafts. Seventeen patients were transplanted from the urgent list, the remaining 84 (83.16%) from the elective list. All but three patients had a choledochocholedochostomy over a straight drain. Bile cultures were taken routinely. The bile drain was removed following cholangiography 6 weeks after OLT. All patients received antibiotic prophylaxis. Ursodeoxycholic acid was used in selected cases. During the first 6 weeks positive bile cultures in absence of clinical and biochemical symptoms of cholangitis were found in 61 (60.4%) cases. Symptomatic cholangitis requiring antibiotic treatment was observed in 19 (18.8%) patients during the first 6 weeks. Two patients required endoscopic sphincterotomy and temporary stenting due to anastomotic stricture (1) or papilla of Vater fibrosis (1). Bile leakage following drain removal was observed in 8 (7.9%) patients. Five of them were treated conservatively, the remaining 3 (2.9%) required surgery (lavage) and stenting. In one case extrahepatic bile duct necrosis was diagnosed requiring reconstruction of the biliary anastomosis. No case of ITBL, bile leak at the anastomostic site, or stricture requiring surgical repair was noted. Despite the high incidence of positive bile cultures most likely related to use of a drain, the overall number of BC was low.

Extracellular matrix proteins, proteolytic enzymes, and TGF-beta1 in the renal arterial wall of chronically rejected renal allografts.

Chronic rejection (CR) is the leading cause of long-term failure of transplanted kidneys. The vascular hallmark is intimal hyperplasia, accompanied by macrophage, foam cell, and T-cell infiltration. Intimal thickening results from the migration and proliferation of smooth muscle cells and increased deposits of extracellular matrix (ECM) proteins, due to release of growth factors and cytokines as well as altered ECM protein turnover. We assessed the content of fibronectin (FN) and transforming growth factor-beta1 (TGF-beta1) as well as the activities of collagenase and cathepsin B and L in renal artery walls of chronically rejected human renal allografts. We investigated renal artery samples from 8 patients with CR undergoing graftectomy, 12 patients undergoing nephrectomy, and 7 organ donors. The results were related to the DNA content of homogenates. Cathepsin B and L activities were significantly higher among those with compared with donors (P =.022). There was a trend toward higher collagenase activity in CR compared with donors and the nephrectomy group. TGF-beta1 was significantly enhanced in CR compared with donors (P =.010), and showed a trend toward higher concentrations in CR compared with the nephrectomy group. The trend was toward lower FN concentrations in CR compared with the nephrectomy group and toward higher concentrations compared with donors. Summarizing, renal CR is accompanied by enhanced proteinase activity, alterations of ECM proteins, and increased TGF-beta1 in the renal artery wall. We conclude that ECM turnover and cytokines play an important role in neointimal formation and CR pathogenesis.
