    ABSTRACT: Quality control procedures in donation and transplantation of organ and tissue, which were started in 2001, are aspects of the activity of Regional Centre for Transplantation. Over the years there has been a significant increase in the number of diagnosed brain deaths that is close to the figure reported in the international literature of 50/60 per million inhabitants (p.m.i). Misidentification of brain death is still the most important cause of loss of organs for transplantation; in fact in Italy, there are some regions that overcome this value, but there are other regions in which the number of brain death identified is still low. Abruzzo and Molise in 2003 achieved the highest registered brain deaths (61 p.m.i.); in 2004, 51; in 2005, 43; and the projection for 2006 is about around 50. For this study we collected data from five hospitals with a neurosurgical unit, which were representative of procurement activity in two regions, because they had identified the most brain deaths, 53/65 in 2005. The data were compared among hospitals and with the Spanish country data (1999-2003), which was avant-garde for the processing of organ donation and transplantation in Europe. Some useful indices to define the theoretical capacity of donation for each hospital (ability to identify brain death, the cause of donor loss) were evaluated for determining the efficacy of the procedure in organ procurement.

    ABSTRACT: Abruzzo is a region in central Italy with a population of 1,262,392. Within this region there are 13 hospitals with intensive care units, four of which have neurosurgical units. The Regional Centre for Transplants in L'Aquila is notified of encephalic deaths in hospitals in Abruzzo and Molise and coordinates organ retrieval and transplantation. Organ donation is a process that involves a whole series of professionals who, operating in a sequential manner in each hospital, make possible the use of a cadaveric organ to give life to a person or improve the quality of life of a patient on a waiting list. Quality control procedures were introduced in 2001 and involve all of the hospitals in the region with intensive care units. The system for quality control was computerized in 2004 and is used in the four hospitals with neurosurgical units (type A hospitals) and in the 13 hospitals without (type B hospitals); the different types of deaths (cause of death, age, etc) are also analyzed with this system. One of the aims of this system is to discover the theoretical donation capacity, taking as benchmark values those resulting from the regional average and those published in international literature, and noting any shortcomings. It has emerged that donor identification is well organized and efficient and this is thanks to a concerted effort that has been made to overcome technical and organizational problems connected to donor detection and donor maintenance during the 6 hours of legal observation. The high percentage of opposition to organ removal, despite the fall registered in the first half of this year (2005), is still above the national average and still remains a critical point in the organ donation process.

    ABSTRACT: The survival and function of a kidney transplant are influenced by numerous immunological and nonimmunological factors. The aim of this study was to evaluate the role of a number of cadaveric donor parameters on transplanted kidney function, and in particular on the occurrence of delayed graft function (DGF) since DGF is one of the most important factors in long-term organ survival. This study looked at 143 patients who underwent kidney transplant of whom 32 displayed DGF. The creatinine levels in organ recipients, which were evaluated during a follow-up that ranged between 6 months and 4 years, were significantly higher among recipients who developed DGF after transplant (1.8 +/- 0.7 vs 1.4 +/- 0.4; P = .02). The following donor parameters were taken into consideration: history of diabetes and hypertension; creatinine levels; inotropie therapy; problems relating to hemodynamics (hypotension and/or cardiac arrest); and cold ischemia time. We observed that a donor history of hypertension (46.8% DGF vs 23.27% no DGF; P = .01) and high levels of donor creatinine prior to organ removal (1.9 +/- 1.2 mg/dL DGF vs 1.2 +/- 0.9 mg/dL no DGF; P = .007) were significant risk factors for DGF among kidney recipients. No significant differences were found for others factors between recipients with versus without DGF.

    ABSTRACT: Medical and technological progress have made kidney transplants an effective, alternative therapy to dialysis for patients suffering from chronic kidney failure. Transplantation improves the quality of life of these patients significantly; however, waiting lists are long and this is because of the attitude of the general public to organ donation, not a lack of medical expertise. In fact, the only limiting factor in kidney transplant is the opposition to donation expressed by the deceased or family members. Herein we outline the distribution of patients on the kidney transplant waiting list in the Regional Transplant Centre for Abruzzo and Molise in L'Aquila, Italy, and highlight the reasons why patients are withdrawn from the list, the main reason being a deterioration in patient condition after long periods of dialysis.

    ABSTRACT: Anti-human leukocyte antibodies (HLA) play a central role in graft survival, particularly in kidney transplantation. The presence of preformed donor specific anti-HLA antibodies is always excluded before transplantation by performing crossmatches using current and historic recipient serum samples. Several recent studies have observed a correlation between HLA antibodies and graft rejection. It has been suggested that these antibodies should be monitored routinely after kidney transplant to predict graft failure. Here in report the results of a study of on serum samples from 111 kidney transplant recipients that were monitored for anti-HLA antibodies using flow cytometry. Anti-HLA antibodies were only detected in four pre-immunized patients and showed the same HLA specificity that was present before the transplantation (in two cases against previous graft antigens). Furthermore, only two patients with functioning grafts developed anti-HLA antibodies, at 1 month and 1 year after the transplantation. However, they were not donor specific, but probably related to posttransplant transfusions. In our study, none of the patients who suffered an adverse event during the first year (including two with histologically documented acute rejection) developed anti-HLA antibodies. These results are probably related to the use of mycophenolate mofetil, which may reduce the incidence of HLA antibodies. We cannot exclude the possibility that antibodies produced by some patients may not be detectable because they are attached to the graft.
