Complications of Transplantation of Kidneys From Expanded-Criteria Donors

BACKGROUND Organ shortage is the primary barrier to kidney transplantation. To maximize organ use, organs from expanded-criteria donors (ECDs) have been used increasingly. Expanded-criteria donors are defined as individuals older than 60 years or older than 50 years with at least 2 of the following risk factors: hypertension, stroke as the cause of death, or serum creatinine concentration greater than 1.5 mg/dL. OBJECTIVE To assess the incidence of complications posttransplantation in ECD kidneys compared with kidneys from standard-criteria cadaveric donors (SCDs). PATIENTS AND METHODS One hundred seventy-two patients received cadaveric renal transplants between January 1, 2006, and August 31, 2008. Donor and recipient data were collected, as well as patient and graft survival and immediate, delayed, or slow graft function. Complication rates for lymphocele, urinary leak, thrombosis, hematoma, urinary tract infection, and cytomegalovirus infection were recorded. Follow-up was for 3 to 35 months, ending on November 30, 2008. RESULTS Overall, mean 1-year graft survival was 86.9%, and mean creatinine concentration was 1.58 mg/dL. One incidence of primary nonfunction (0.6%) was observed. More than 25% of transplanted kidneys were from ECDs. No significant differences were noted in postoperative complications between recipients of ECD or SCD organs. CONCLUSION The rate of complications in recipients of ECD and SCD kidneys is comparable.

Surgical complications observed in simultaneous pancreas-kidney transplantation : Thirteen years of experience of one center

SIMULTANEOUS pancreas and kidney transplantation (SPKTx) is the procedure of choice for a majority of transplant candidates with end-stage renal disease and diabetes mellitus. Recent evidence supports its benefits on the maintenance of normoglycemia and the arrest or even possibily of reversal of diabetic complications, such as vasculopathy, nephropathy, and neuropathy. However, pancreas transplant has been associated with the highest surgical complication rate of all the routinely performed organ transplant procedures. A significant number of pancreas grafts are lost early post-transplant secondary to surgical complications. Over the last decade, the operative procedure has been refined and immunosuppressive regiments have improved such that 1-year graft survival routinely exceeds 75%. The purpose of this study was to assess our improved results and to determine other risk factors that may help us decrease the complication rate further.

Partnership for Transplantation: A New Initiative to Increase Deceased Organ Donation in Poland

Despite the long-standing history of transplantation, the shortage of organs has remained its most restrictive factor. In 2010, the number of actual deceased organ donors in Poland was 13.5/million population (pmp). However, a huge difference in organ recovery rates is evident between various regions, eg, 32 pmp, in western Pomerania compared with 1-3 pmp in southern districts. A substantial number of patients who die while awaiting organ transplantations could be saved were effective programs able to overcome barriers in deceased organ donation. Such programs, eg, the European Donor Hospital Education Program, Donor Action, European Training Program on Organ Donation, United States Collaborative in Donation were introduced several years ago, but after transient improvements there has not been real progress. A new comprehensive program-Regional Partnership for Transplantation-was initiated a year ago in 4 districts of southern Poland by the Polish Union for Transplantation Medicine. The letter of intent to activate the donation program was signed by the local administration, the president of the local medical school, president of the Physicians Chamber, transplant centers, the Polish Union for Transplantation, and the Polish Transplant Coordinating Center. The plan of action included training of in-hospital coordinators, visits to all regional hospitals in company of a representative of the hospital founding body, examination of the real donation pool and the need for participation in a donation program training and education of the hospital staff in legal and organizational aspects of donation, brain death recognition, and various aspects of donor care. In addition, the program included communication skills workshops for intensive care unit physicians (with participation of 2 actors, an experienced anesthesiologist, and a psychologist), lectures for high school and university students and for hospital chaplains as well as alumni of higher seminaries. The preliminary results (after the first year) showed 40%-70% increases in activity of the local hospitals in the organ donation process.

Surgical site infections in the early posttransplant period after simultaneous pancreas-kidney transplantation.

OBJECTIVE Urinary tract infection (UTI) is among the common infection in simultaneous pancreas-kidney transplantation (SPKT). PATIENTS AND METHODS The study included 26 adult patients undergoing SPKT between September 2001 and December 2006. All the patients were followed prospectively for UTI during the first 4 weeks after surgery. Urine samples were investigated for bacteriologic cultures. The micro-organisms were identified in accordance with standard bacteriologic procedures. Susceptibility testing was carried out using Clinical and Laboratory Standards Institute (CLSI) procedures. RESULTS Among 77 urine specimens obtained from all recipients during the first month, there were 30 isolated bacterial strains. The most common were Gram-positive bacteria (53.3%) with predominance of enterococci (75%) associated with high levels of aminoglycoside resistant strains (HLAR; 58.3%) and vancomycin-resistant strains (VRE; 25%). Gram-negative bacteria were detected in 46.7% of positive cultures. CONCLUSIONS In our study, enterococci predominated as 75% of Gram-positive isolates. The increased proportion of multi-drug-resistant bacteria, which can caused severe UTI in patients after SPKT, may be due to the frequent use of prophylaxis of bacterial infections in patients.

Etiologic agents of bacteremia in the early period after simultaneous pancreas-kidney transplantation.

BACKGROUND Bacteremia is among the known complications in simultaneous pancreas-kidney transplantation (SPKT). This study evaluated the frequency of microbial isolates and their susceptibility profiles among cultures of clinical samples obtained from blood and from the tips of blood vessel catheters of 26 SPKT recipients suspected of bacteremia in the early posttransplant period. PATIENTS AND METHODS Data on microbiologic blood cultures of 26 adult patients undergoing SPKT were collected prospectively from 2001 to the end of 2006. The isolation and identification of cultured microorganisms were performed according to standard microbiological procedures and commercially available tests. The susceptibility of the strains to antibacterial agents was established by the Clinical and Laboratory Standards Institute guidelines. RESULTS All patients were followed prospectively for the first 4 weeks after surgery. Among 66 clinical samples, there were 23 microbial isolates from blood samples of 17 recipients and catheter tips of 12 recipients. The most common isolates were Gram-positive bacteria (73.9%) with domination of staphylococci (64.7%) and MRCNS strains (81.8%). Gram-negative bacteria comprised 17.4% of positive cultures, whereas yeast-like fungi, 8.7% with a predominance of Candida glabrata. CONCLUSION Our study showed predominately Gram-positive bacteria in 73.9% of isolates. The increased proportion of multi-drug-resistant bacteria and fungi to antimicrobial agents may be due to the frequent use of these agents for prophylaxis of bacterial infections in patients.

Simultaneous pancreas-kidney transplantation: analysis of donor factors

There are no urgent indications for simultaneous pancreas-kidney transplantation. So our policy is to harvest only a pancreas in good biologic condition. The criteria for acceptance of a pancreas donor are: age 15 to 40 years, ICU stay < 7 days, no clinical signs of infection, negative virologic status, no history of hypotension or cardiac arrest, serum amylase elevation below three times normal values, controllable hyperglycemia, no history of pancreatic disease, no history of abdominal trauma damaging the organ, no history of alcohol addiction, BMI < 25, no functional or anatomical lesions of the kidneys, and expected ischemia time less than 12 hours. The proper selection of a pancreas donor allows one to achieve good insulin secretion immediately after transplantation. In 2000 to 2002 all 20 pancreases transplanted at transplant center displayed immediate secretory function after transplantation.

Attitude of Healthcare Professionals: A Major Limiting Factor in Organ Donation from Brain-Dead Donors

Public attitude toward deceased donor organ recovery in Poland is quite positive, with only 15% opposing to donation of their own organs, yet actual donation rate is only 16/pmp. Moreover, donation rate varies greatly (from 5 to 28 pmp) in different regions of the country. To identify the barriers of organ donation, we surveyed 587 physicians involved in brain death diagnosis from regions with low (LDR) and high donation rates (HDR). Physicians from LDR were twice more reluctant to start diagnostic procedure when clinical signs of brain death were present (14% versus 5.5% physicians from HDR who would not diagnose death, resp.). Twenty-five percent of LDR physicians (as opposed to 12% of physicians from HDR) would either continue with intensive therapy or confirm brain death and limit to the so-called minimal therapy. Only 32% of LDR physicians would proceed with brain death diagnosis regardless of organ donation, compared to 67% in HDR. When donation was not an option, mechanical ventilation would be continued more often in LDR regions (43% versus 26.7%; P < 0.01). In conclusion, low donation activity seems to be mostly due to medical staff attitude.

Implementation and Sustainability of European Training Program on Organ Donation in Poland: Results and the Impact on Donation Indicators.

BACKGROUND Hospital training called ETPOD-Essentials in Organ Donation-was introduced in Poland in 31 hospitals with under-utilized potential of donation. The aim of this study was to assess the effect in hospitals included and not included in program, before and after trainings. METHODS The number of potential and effective donors, organs used, and number (%) of family refusals were compared at 10 and in 20 months after the training and in equal periods before. RESULTS In trained hospitals, the number of potential donors increased (17% in 10 months, 10% in 20 months); in remaining hospitals, donors increased in 5% in both periods. In hospitals included in ETPOD, the number of effective donors increased (2% and 4.5%); in the whole country, donors also increased (5.6% and 2.7%). In ETPOD hospitals, the number of utilized organs increased (14.5% and 8.5%); in the rest, the increase was 3% and 7%. In trained hospitals, family refusals increased from 6.9% to 16.2% and from 8.9% to 10.7%; in the whole country, family refusals decreased from 11.7% to 11% in the short term and increased from 9.6% to 12.1% in the long term. CONCLUSIONS In hospitals involved in the ETPOD program, the increase in organ donation is greater than in the rest of hospitals. Distinct benefit was observed in consent to organ donation.

Survey on Attitudes and Knowledge on the Organ Recovery From Deceased Donors in Roman Catholic Nuns and Priests

UNLABELLED Deceased donors (DD) organ recovery rate in Poland has never been satisfactory but over the years kidney transplantation from deceased donors has reached the level of 26 transplants/pmp. In 2007 due to a number of reasons, a dramatic fall of organ recovery rate from deceased donors (DD) occurred. The survey on public attitude toward organ transplantation carried out in the same year showed a large reduction of the public trust toward medical profession. Since then, the number of kidney transplantations has never come back to its level from 2006, regardless of a positive attitude toward organ transplantation. The attitude and knowledge survey was recently carried out in 100 physicians and 100 nurses employed in one large district hospital. The results of the attitude survey among the hospital staff showed that the level of knowledge among nurses corresponded to their age and the time since graduation. Younger nurses showed much more appreciation and knowledge toward recovery of organs from the deceased donors. Survey among physicians indicated some hesitation toward recognition of the brain death. In the present paper results of the survey on attitude and knowledge toward organ transplantation among nuns (98 nuns), priests (100 priests) and students (98 students) of the Theological School living in the same area are presented. Despite quite high (>60%) acceptance of the deceased donation, one third of questioned population showed lack of knowledge not only on existing legal regulations, but also of important documents issued by the Catholic Church. CONCLUSIONS Improvement of transplantation program in Poland requires extensive educational program among various parts of the society: most importantly among physicians, nurses and priests. The Partnership for Transplantation program has been directed to achieve these goals.

Activity of Hospital Transplant Coordinators in Malopolskie Province (Poland)

BACKGROUND In Poland as well as in other European countries, the number of organs from deceased donors is too small to meet the needs of transplantation therapy. METHODS This situation can be improved by increasing the number of hospital transplant coordinators in hospitals with potential of donation. Since 2010, 200 Polish hospitals have employed coordinators whose role is to recruit deceased organ donors, to monitor the potential of donation (quality assurance program), and to run the training courses. In Malopolskie Province, there are 26 hospitals in which organ procurement from brain-dead donors is possible. In 13 hospitals, donor transplant coordinators have been employed. The objective of this study was to evaluate the activity of hospitals in Malopolskie Province in the field of donor recruitment before and after employment of coordinators (19 months before and after). For the purpose of the study, the number of hospitals with positive effects and with no effects of coordinator employment was calculated, and several donation rates were compared in the period before and after employment of the coordinator. We also compared the number of deceased organ donors in 13 hospitals employing a coordinator and in 13 hospitals without a coordinator. RESULTS The desired impact of employment of coordinators in Malopolskie Province measured by improvement of organ donation rates was observed in half of the hospitals (7 of 13; 54%) with a transplant donor coordinator. The number of potential organ donors increased by 100% (from 24 to 48), and the number of actual organ donors increased by 113% (from 16 to 34). The percentage of family objections to organ donation decreased (from 17% to 8%). The best result of employing coordinators was observed at university hospitals and multidisciplinary hospitals and at hospitals in which the coordinator was a physician. The worst effect was recorded at county hospitals. CONCLUSIONS The employment of hospital transplant coordinators in Malopolskie Province has a global impact on the increase of the number of actual organ donors in that region and improvement of organ donation rates, but it is effective only in half of the hospitals with coordinators. It indicates that other measurements should also be undertaken to run donation programs.
