RESUMEN
BACKGROUND: The national protocol for the handling of high-urgency (HU) liver organ procurement for transplant is administered by the Italian National Transplant Center. In recent years, we have witnessed a change in requests to access the program. We have therefore evaluated their temporal trend, the need to change the access criteria, the percentage of transplants performed, the time of request satisfaction, and the follow-up. METHODS: We analyzed all the liver requests for the HU program received during the 4-year period of 2014 to 2017 for adult recipients (≥18 years of age): all the variables linked to the recipient or to the donor and the organ transplants are registered in the Informative Transplant System as established by the law 91/99. In addition, intention to treat (ITT) survival rates were compared among 4 different groups: (1) patients on standard waiting lists vs (2) patients on urgency waiting lists, and (3) patients with a history of transplant in urgency vs (4) patients with a history of transplant not in urgency. RESULTS: Out of the 370 requests included in the study, 291 (78.7%) were satisfied with liver transplantation. Seventy-nine requests (21.3%) have not been processed, but if we consider only the real failures, this percentage falls to 13.1% and the percentage of satisfied requests rises to 86.9%. The average waiting period for liver transplantation (LT) is 1.7 days and most requests (74%) are met in less than 24 hours, if we consider the hours between the registration of the request and the donor reporting . The percentage of late retransplantations is 2.1%. The clinical indication for HU-LT that appears to improve over time is hepatic artery thrombosis (82.5%). The overall 1-year patient survival is 68.3%. The overall 1-year graft survival, performed on all the patients, is 89% and all the indications for HU-LT appear to go well over time with an average survival rate greater than 85%. CONCLUSIONS: The indications for HU-LT are changing according to the changes in the hepatologic field in recent years. The centralized management of requests has proven to be successful in optimizing responses. Urgent LT is confirmed to be lifesaving in its timeliness.

The Italian Gate to Europe (IGE) was established in April 2005 to supply a single national coordinating center for the exchange of organs and patients with the rest of Europe. When an organ is offered from Italy, the IGE ascribes it to the first foreign organization that accepts it on a first-come, first-served basis. In the case of offers from abroad, the IGE allocates the organ to one of the three Italian Interregional Centres in rotation. On the basis of international agreements, the IGE also manages the transfer of foreign patients to Italian transplant centers. The first 15 months of activity have been compared with the previous period of the same length. The IGE managed 353 contacts. 53 organs were transplanted in Italy versus 19 in the previous period. Seven foreign patients received liver transplantations in Italy. The increase in imported organs could be a function of IGE creation, since it allowed a reduced response time to offers and guaranteed the participation of all Italian centers in the program of international exchanges with a subsequent increase in the pool of recipients and equitable distribution of transplanted organs. The drop in the number of exported organs was a probable a consequence of increased acceptance criteria of Italian centers. The mentioned international agreements have allowed us to better meet the health care needs of foreign citizens who live in countries with low per-million-population donation rates with no detriment to the probability of Italian citizens being transplanted.

The aim of this study is to evaluate the incidence of malignant tumors in cadaver donors and the possibility of neoplastic disease transmission to the recipients in the Organizzazione Centro Sud Trapianti (OCST) area. Among 1744 potential donors identified from 2003 to 2005, 125 (7.1%) showed an elevated malignant neoplastic risk. In 2003 a malignant tumor was diagnosed in 60 donors of mean age 59.6 +/- 19.9 years (median 62.5, M:36 F:24); in 2004, 33 donors of mean age, 61.4 +/- 15.9 years (median 63, M:19 F:14); in 2005, 32 donors of mean age of 62.8 +/- 15.5 years (median 65.5, M:20 F:12). Prostatic cancer was the most common tumor (23.2%). In 101 of 125 cases (80.8%) the tumor was diagnosed before organ retrieval, in 23 (18.4%) cases, during the donor operation but before the transplant, and in one case (0.8%) after transplantation. Each tumor was evaluated according to the histologic types and grades. From 12 of those donors with neoplasia, 24 organs were retrieved (10 livers, 11 kidneys, 3 hearts) transplanted in 23 recipients (one liver-kidney combined transplant). Three recipients died during the perisurgical period due to causes unrelated to the tumor and therefore were not considered in the follow-up evaluation. Among the remaining nine recipients who had a mean follow-up of 38.83 months (range 9-42), no donor-transmitted disease has become apparent by imaging control. A careful donor evaluation including histologic grading and strict application of Centro Nazionale Trapianti guidelines allowed us to use donors with malignant tumors in selected cases with an apparently reduced risk of transmitted neoplastic disease.

INTRODUCTION: The outcome of transplantation activities depends on a variety of unpredictable factors. Up-to-date criteria on organ allocation foresee an efficient transport chain along with compliant performance parameters. METHODS AND OBJECTIVES: The Centro Nazionale Trapianti and the Department of Civil, Chemical, Environmental, and Materials Engineering of the University of Bologna (respectively, CNT and DICAM) have been updating a national database of organ transplantation activities to investigate performance parameters and the main causes of disruption. RESULTS: Between June 2015 and July 2016, 617 of 1061 organs have been shipped by air (making for 486 flight events), of which 407 were accompanied by medical equipment. Origin/destination and distance matrixes have been drawn for both road and air transport. Each airport node is ranked based on the n° of organs ingoing/outgoing and each route link on its frequency. Performance parameters such as average speed, distance covered, and time have been computed and compared with each organ's cold ischemia time (CIT). Average distance frontiers are rather homogeneous, but much effort is necessary to reduce the number of events performed with approximately 90% or more of CIT spent. CONCLUSIONS: The monitoring of organ transplantation activities' performance is a standalone action within Europe to support strategic policies to optimize the system. Thus, a clearer awareness on performances and issues related to organ transport has been made possible: analyses show that the higher uncertainty associated with total time of displacement by air is due to the steps which take place by road (length and paths must be optimized) and lung transports generally perform weaker than heart transports due to longer average distances travelled and smaller average speeds, often resulting in a total displacement time greater than 90% of CIT.

INTRODUCTION: Antivirals direct acting (DAA) for hepatitis C virus (HCV) have brought a revolution in the field of transplantation. It is likely to think that in the future patients on the waiting list for liver transplantation (LT) will no longer be registered for HCV-related cirrhosis but for liver disease from other causes. On the eve of this change, we show a snapshot of the Italian waiting list for LT. METHODS: From October 1, 2012 to September 30, 2013, we estimated the total number of patients on the liver waiting list as intention to treat (ITT), the number of incident cases, and the delistings, particularly in the HCV positive (HCV+) population. Gender, median age, etiology and prognosis of liver disease, presence of hepatocellular carcinoma (HCC), reason for delisting, mean waiting time for LT, and rate of death on waiting list were evaluated. RESULTS: In the time period, there were 517 new patients who were HCV+ (median age, 53 years): 255 (49.3%) mono-infected with HCV, 236 (45.7%) co-infected with HCV and hepatitis B virus (HBV), 11 (2.1%) co-infected with HCV and human immunodeficiency virus (HIV), and 15 (2.9%) co-infected with HCV, HBV, and HIV. The median model for end-stage liver disease (MELD) score at listing was 17 and HCC was present in 206 (39.8%) cases. HCV+ patients delisted were 442 (61.9%), 355 (80.3%) for LT. The mean waiting time to transplantation was 1.9 months; the percentage of death was 7.6%. CONCLUSIONS: This snapshot of the waiting list for LT in the year before the advent of DAA drugs will allow us to assess whether and how they will change the waiting list for LT when we start to look at the impact of new therapies on the waiting list.

BACKGROUND: Organ transplantation, the treatment of choice in organ failure, is penalized by the lack of organs. Because the increase in the number of donors is not proportional throughout the different age groups, there is no increase in lung transplantations. The aim of this work was to analyze the use of available lungs and evaluate strategies that may help increase transplantations. METHODS: We analyzed the activity of lung transplantation in 2015, divided into various allocation programs. We also examined the surplus organs, in particular, their origin, their destination, their offer's outcome, the characteristics of the donor and the proposed organ, and the reasons for rejection. RESULTS: In 2015, 112 lung transplantations were performed: 66 (68.9%) with regional organs, 46 (41.1%) with extraregional organs; 21 (45.6%) of these were allocated as emergencies/return, and 25 (54.4%) as surplus (19 in the North macroarea, 6 in the South macroarea). The number of surplus lungs was 148: 67 from the North macroarea, 71 from the South macroarea, and 10 from abroad. No organ procured in the North macroarea was transplanted in the South macroarea, whereas 6 lungs coming from the South macroarea were transplanted in the North. CONCLUSIONS: The acceptance criteria are not the same in different transplant centers and they include not only clinical parameters, but also ischemia time and composition of the waiting list at the time of the offer, quality and accessibility of the intensive care units where the donor is located, and organizational reasons. Offering organs which can not be transplanted within the region to other centers, without clinical foreclosures is a system that increases transplant activities by maximizing the available resources.

INTRODUCTION: From 2011 a program was developed for liver transplant recipients with Model for End-Stage Liver Disease (MELD) score ≥30. We examined its effectiveness and impact on the other subjects on the waiting list. MATERIALS AND METHODS: We analyzed requests received between January 2011 and May 2012 for the primary pathology, the outcome, the average waiting time, and the origin of the organ. We examined the ordinary waiting list for mortality rates and numbers of transplantations over this period (group A) versus a comparable preceding period (group B). RESULTS: There were 38 requests for 33 patients. Their primary pathologies were cirrhosis associated with viral infection (n = 15), delayed graft failure (DGF; n = 5), biliary cirrhosis (n = 4), hepatocellular carcinoma (HCC; n = 3 including 2 with cirrhosis), cryptogenic cirrhosis (n = 3), postalcoholic cirrhosis (n = 2), metabolic disease (n = 2), and iatrogenic disease (n = 1). Of the requests, 25 were successfully dealt with, whereas 5 requests were temporarily suspended and 2 were permanently suspended because of better or worse patient conditions. There were 6 deceased patients. Transplanted organs came from the inter-regional area in 64% of cases. The average waiting time was 5.9 days. Within group A were a 311 transplantations among 723 waiting list patients on with a 13.7% mortality rate. Within group B were 305 transplantations among 871 wait-listed patients with a 14% mortality rate. DISCUSSION: The liver transplantation program for recipients with MELD scores ≥ 30 allowed recipients in critical condition to receive grafts without altering substantially the opportunities for recipients on the elective waiting list.

Law number 91, dated April 1, 1999, established an organizational model for the activities of donation, retrieval, and transplantation of organs consisting of 4 levels: national, interregional, regional, and local. After 12 years this organizational project, called the "National Transplant Network," has reached an excellent level of effectiveness and efficiency. Since 2001 regional administrative districts have been entrusted increasingly with responsibilities concerning health. In 2008 health federalism was approved and in 2010 the federal health fiscal system entered in force. In a country with a federal organization, where regional districts are completely autonomous, is there a reason to still have a national transplant center and 3 interregional transplantation centers? We have developed a hypothesis on the function of Interregional Transplant Centers (CIR). The risk of federalism is the fragmentation of the National Healthcare System. To adequately meet the needs of citizens, smaller regions should sign agreements with larger regions regarding transplantation programs that require a large pool of donors whereas they could retain management of patients during the presurgery and postsurgery phases. The CIR should be committed to increase organ donation, to establish shared protocols and procedures, to disseminate knowledge, and to ensure equal access to health care. In conclusion, the adoption of health and fiscal federalism provides an opportunity to build healthcare systems to optimize resources. The network model should be kept but it is necessary to overcome localism and create positive federalism.

The 21 heart transplantations in Centre-Sud Transplant Organization (OCST) is a stable number despite increasing donations, especially among subjects aged 50 to 60 years. The aim of the present study was to evaluate the possibility to increase the usage of marginal hearts through dipyridamole ecostress. From 2008 to 2010 we analyzed OCST donors at 74 donation sites for echocardiography (31 yes versus 43 no) and heart utilization: (1) principal sites (n > 13) versus (2) minor sites (n < 13). Among 2145 signaled donors, there were 900 (42%) effective donors, including 816 (38%) utilized organs from 387 subjects of age <50 years; 189, 50 to 60 years and 240, >60 years with 217 (90%); 24 (10%), and 3 (1%) utilized hearts respectively to the analyzed sites, the utilized donors with echocardiography were 373: 259 (69.4%) versus 114 (30.5%) from those without such a service. Utilized donors between 50 and 60 years came from principal sites (n = 50), minor sites (n = 7) or those without an echocardiagram (n = 16). Utilized heart donors in each type of site were eight, one, and six, respectively. We believe that it may be possible to increase the total number of heart transplantations using dipyridamole stress-test echocardiography at the sites with major retrieval activity to increase heart transplantation among donors in the age range of 50 to 60 years.

INTRODUCTION: In 2005 the Italian National Transplant Centre (CNT) signed a cooperation agreement with the Hellenic Transplant Organization (HTO) fostering the transfer and transplantation of urgent Greek liver patients at Italian transplantation centers. So as to not reduce access to transplantation for Italian patients, the agreement provided compensation for organs allocated to Greek transplant recipients. The aim of this study was to analyze the flow of patients from Greece to Italy and the number of received livers to consider the possibility to extend this kind of agreement to other countries, so that this should not penalize Italian recipients. MATERIALS AND METHODS: The agreement provides the possibility for Greek patients affected by acute disease to be transferred to Italian transplantation centers participating in the agreement. Until 2008 livers transplanted into Greek recipients were returned through a preferential offer of surplus Greek organs, whereas from 2009 an obligation of payback was introduced. RESULTS: During the reviewed period requests for transfer, transferred patients, and number of patients who later underwent transplantation in Italy were 56, 26, and 23, respectively. Livers offered by the Greek organization that were accepted, transferred, and transplanted in Italy have been 82, 50, and 44, respectively. DISCUSSION AND CONCLUSIONS: According to our analysis, the cooperation has had as positive impact for both Greece, which has difficulties transplanting urgent recipient because of the low number of donors, and for Italy, which is not penalized by the use of an organ in a Greek recipients, but is also rewarded for helpfulness.

The aim of the study was to evaluate the experience of the Centre-Sud Transplant Organization (OCST) area using cadaveric donor with neoplastic diseases to evaluate the possibility of transmission to recipients. From January 1, 2003, to December 31, 2010, the neoplastic risk has been reported to be 5.4% (377/4654 referred donors). In 2003, the number of donors with a tumor and their mean age were respectively: 60 (10.3%) and 59.6 ± 19.9; 2004: 33 (5.2%) and 61.4 ± 15.9; 2005: 32 (6%) and 62.8 ± 15.5; 2006: 46 (7%) and 60.7 ± 19.1; 2007: 51 (7%) and 58.9 ± 16; in 2008: 58 (7%) and 59.7 ± 19.6; 2009: 47 (7%) and 57 ± 26; 2010: 49 (7%) and 64 ± 16. The organ most affected by tumor has been the central nervous system (18%). The tumor was diagnosed before in 325 (86%) cases, versus during organ retrieval in 48 (12.7%) donor operations but before, which four cases (1%) occured after transplantation. According to the histological types and grades, 28 evaluated donors (8.2%) were suitable for transplantation. The histological types were: thyroid carcinoma (n = 3); prostate carcinoma (n = 8), renal clear cell carcinoma (n = 7), oncocytoma (n = 1), meningiomas (n = 2), dermofibrosarcoma (n = 1); verrucous carcinoma of the vulva (n = 1), colon adenocarcinoma (n = 1), grade II astrocytoma (n = 1), adrenal gland tumor (n = 1), gastric GIST (n = 1), oligodendroglioma (n = 1). Forty-five organs were retrieved (22 livers, 19 kidneys, 3 hearts, and 1 pancreas) and transplanted into 44 recipients with 1 liver-kidney combined transplantation. Four recipients died due to causes not related to the tumor. No donor-transmitted tumor was detected among the recipients. Donation is absolutely not indicated in cases of tumors with high metastatic potential and high grades. Performing an accurate evaluation of the donor, taking into account the histological grade, currently can allow, organ retrieval and transplantation with an acceptable risk.

Validity of living donor kidney transplantation is universally accepted. In contrast, after enthusiastic adoption in the 1990s, living donor liver transplantation has decreased in recent years. The aim of the present study was to evaluate retrospectively the current use of this form of donation in Italy by comparing liver and kidney cadaveric and living donations from 2002 to 2010. The number of liver transplantations from living donors has decreased from 34 in 2002 (3.9% of total) to 13 in 2010 (1.3% of total). In contrast, kidney transplantation from living donors increased from 126 (7.9% of total) to 186 (11% of total). We observed that living donations for kidney transplantation are still underused, especially with unrelated donors. Living donor liver transplantation has decreased in recent years; this procedure should be reserved to centers with particular expertise. It would be appropriate to implement programs to increase the attention of health professionals and the general population and to integrate living donations into programs of deceased organ donation.

UNLABELLED: Starting from the report on medical errors published in 1999 by the US Institute of Medicine, a number of different approaches to risk management have been developed for maximum risk reduction in health care activities. The health care authorities in many countries have focused attention on patient safety, employing action research programs that are based on quite different principles. MATERIALS AND METHODS: We performed a systematic Medline research of the literature since 1999. The following key words were used, also combining boolean operators and medical subheading terms: "adverse event," "risk management," "error," and "governance." Studies published in the last 5 years were particularly classified in various groups: risk management in health care systems; safety in specific hospital activities; and health care institutions' official documents. Methods of action researches have been analysed and their characteristics compared. Their suitability for safety development in donation, retrieval, and transplantation processes were discussed in the reality of the Italian transplant network. DISCUSSION: Some action researches and studies were dedicated to entire national healthcare systems, whereas others focused on specific risks. Many research programs have undergone critical review in the literature. Retrospective analysis has centered on so-called sentinel events to particularly analyze only a minor portion of the organizational phenomena, which can be the origin of an adverse event, an incident, or an error. Sentinel events give useful information if they are studied in highly engineered and standardized organizations like laboratories or tissue establishments, but they show several limits in the analysis of organ donation, retrieval, and transplantation processes, which are characterized by prevailing human factors, with high intrinsic risk and variability. Thus, they are poorly effective to deliver sure elements to base safety management improvement programs, especially regarding multidisciplinary systems with high complexity. CONCLUSION: In organ transplantation, the possibility to increase safety seems greater using proactive research, mainly centred on organizational processes together with retrospective analyses but not limited to sentinel event reports.

We describe a case of type II mixed cryoglobulinemia, with monoclonal IgMkappa rheumatoid factor, associated with visceral leishmaniasis caused by Leishmania infantum. Involvement of Leishmania antigen(s) in the formation of cryoprecipitable immune complexes was suggested by the fact that cryoglobulinemic vasculitis subsided after antiparasite therapy and that anti-Leishmania antibodies, as well as rheumatoid factor, were enriched in the cryoprecipitate. We observed 2 additional patients with visceral leishmaniasis and cryoglobulinemic vasculitis. All 3 patients had seemingly contracted leishmaniasis in Italy, were hepatitis C virus negative, and were initially diagnosed as having autoimmune disorders. These findings indicate that Leishmania can be an etiologic agent of type II mixed cryoglobulinemia. This parasitosis should be taken into consideration in the differential diagnosis of vasculitides in endemic areas.
