Diagnostic value of presepsin for bacterial infection in cirrhosis: a pilot study
Introduction: Presepsin (or sCD14) has been identified as a protein whose levels increase specifically in the blood of patients with bacterial infections. In this study, we evaluated the clinical performance of sCD14 and its usefulness in the early diagnosis of bacterial infection in decompensated cirrhotic patients. Materials: Seventy patients were enrolled in this study. The mean age of patients was 49.5 years, and 21 were women and 49 men. The heparinized whole blood for the PATHFAST test was used in the evaluation of bacterial infection (T0). The test was repeated after 48 hours (T1); at 96 hours (T2); at 144 hours (T3); then at 15 days (T4) to monitor the clinical responses to therapeutic interventions. Results: Forty-nine patients tested positive for sCD14. The mean sCD14 level was 1854 ± 1744 pg/mL. Microbiological findings confirmed the presence of bacterial infections within 84 ± 4.8 h from enrollment in all 49 positive patients. Thirty-eight patients were considered responders to empirical antibiotic therapy with a decrease of presepsin at the different time points, while an increased level of sCD14 was highlighted in 11 patients. When the test was performed, 45% of the patients showed no signs or symptoms of bacterial infection. At 30 days of follow-up 43 patients survived, and 6 patients died from septic shock. Conclusions: The PATHFAST test highlighted the presence of infection in a very short time (15 minutes), and the presepsin could be considered an early biomarker in patients with cirrhosis. A greater number of patients are necessary to confirm these data

[Pre-emptive renal transplantation from deceased donor]
Preemptive transplantation from deceased donors is an important issue due to its ethical and clinical implications. In this paper, two nephrologists discuss the problem from different angles, expressing their opinion on specific points and highlighting the limitations and advantages. The first point discussed relates to the advantages of preemptive renal transplant from a deceased donor versus dialysis. The second point considers the possibility that the former could reduce the already limited resources for patients on the transplant waiting list. The third point discusses whether preemptive transplant should be reserved for patients with particular background diseases. The last discussion point relates to the possibility that a preemptive program from deceased donors could hamper an already limited living donor program. The ethical aspects are examined separately by a bioethicist who critically evaluates all discussion points and lists some principles that should guide clinicians, before or after starting dialysis, in the proper use of renal transplant, an efficacious but scarce resource
The organizational model of the interregional transplant agency Organizzazione Centro-Sud Trapianti.
In Italy, all donation and transplant activities were officially disciplined in 1999 by the law 91 of April 1, 1999. This law enacted a coordinator-based model of transplantation, instituted the National Center for Transplantation (Centro Nazionale Trapianti-CNT), and endorsed the existing interregional transplant agencies (ITA), such as the Nord Italia Transplant program (NITp), the Associazione InterRegionale Trapianti (AIRT), and the Organizzazione Centro-Sud Trapianti (OCST). Within its borders each ITA has adopted its own organizational model; there is no overt centralized control exerted by the CNT according to the law 91/1999. The aim of the current work is to report on the organizational model adopted by OCST, the ITA gathering the Italian regions of Abruzzo, Basilicata, Calabria, Campania, Latium, Molise, Sardinia, Sicily, and Umbri
Organizzazione Centro-Sud Trapianti: Outcome analysis 1999 to 2002
Background. The Organizzazione Centro-Sud Trapianti (OCST), which was created in 1998, is organized into eight regional areas, each referring to a local Regional Transplant Coordinating Center. Organs are primarily allocated to meet the demands of transplant C, centers in each regional area. Urgencies, pediatric grafts, and paybacks are managed by an Interregional Transplant Coordinating Center. The aim of the current work is to report on the impact of introduction of OCST on organ donation and transplant activity over the period from 1999 to 2002. Materials and methods. A retrospective analysis of donor and transplant data charts over the period from 1999 to 2002 focused on outcome analysis based on donor epidemiological data, cause of death, reasons for discards and grafts performed at OCST local transplant centers. Results. From 1999 to 2002, we observed a remarkable increase in organ donation from 8.8 to 22.5 donors per million people. Donor epidemiology showed an increase in median a(ye and stroke incidence rates and a decrease in trauma cases. The nonharvested donor rate rose steadily over the study period, plateauing at 58%, which was compensated for by a threefold increase in donation. Family oppositions ranged as high as 35.5% on average, despite public efforts to support donation. Transplant activity rose by 76%. Conclusions. The institution of OCST and the efforts from central and regional authorities have yielded a significant increase in organ donation and transplant activity rates over the period from 1999 to 2002. Major areas of concern are the high opposition rate and the decreasing quality of harvested grafts. Long-term analysis is underway to assess the impact of OCST on the quality of transplants performed in the catchment area
