Italy was the first Western country to face the COVID-19 pandemic. Here we report the results of a national survey on kidney transplantation activity in February and March 2020, and the results of a three-round Delphi consensus promoted by four scientific societies: the Italian Society of Organ Transplantation, the Italian Society of Nephrology, the Italian Society of Anesthesia and Intensive Care, and the Italian Group on Antimicrobial Stewardship. All 41 Italian transplant centers were invited to express their opinion in the Delphi rounds along with a group of seven experts. The survey revealed that, starting from March 2020, there was a decline in kidney transplantation activity in Italy, especially for living-related transplants. Overall, 60 recipients tested positive for SARS-CoV2 infection, 57 required hospitalization, 17 were admitted to the ICU, and 11 died. The online consensus had high response rates at each round (95.8%, 95.8%, and 89.5%, respectively). Eventually, 27 of 31 proposed statements were approved (87.1%), 12 at the first or second round (38.7%), and 3 at the third (9.7%). Based on the Italian experience, we discuss the reasons for the changes in kidney transplantation activity during the COVID-19 pandemic in Western countries. We also provide working recommendations for the organization and management of kidney transplantation under these conditions.

As reported in the literature, the mortality rates for patients with Acute Hepatic Failure (AHF) approaches 80% in cases in which liver transplantation is not possible. Post-transplant mortality mostly depends on the severity of the neurological condition at the time of the operation (20% in I-II degree coma patients and 44% in III degree coma patients). The primary indications for liver transplantation in AHF are Fulminant Hepatitis (FH)(93%), Subfulminant Hepatitis (5%) and other indications (2%). Other causes of AHF are Primary Non-Function (PNF) and Delayed Function (DF), which occur in 7-10%. Therefore it becomes necessary to monitor the patients with a Liver Support Device to be able to improve the clinical condition of the patients before liver transplantation (LT). In our experience we used the Molecular Adsorbent Recirculating System (MARS) (MARS Monitor; Teraklin AG, Rostock Germany), which enables the selective removal of albumin-bound substances accumulating in liver failure by the use of albumin-enriched dialysate. The system is used as a bridging device to orthotopic liver transplantation (OLT) of patients with FHF. We studied 34 patients, including 16 males and 18 females: 9 were affected by Primary-Non-Function (PNF), nine by Fulminant Hepatitis (FH), six by Delayed-Non-Function (DNF), and ten by Acute on Chronic Hepatic Failure (AOCHF). The average age of the patients was 41.8 years and the average number of applications was 6.4; the median length of application was about eight hours. The parameters that we monitored, before and after each treatment, were neurological status (EEG, cerebral CT, Glasgow Coma Score), haemodynamic parameters, acid base equilibrium, and blood gas analysis. We also monitored hepatic and renal function. In addition, the clinical conditions of the patients were monitored using kidney and liver ultrasound/ultrasonography (US). Inclusion criteria were bilirubin > 15 mg/dL, ammonia > 160 micro g/dL and a Glasgow Coma Score between 6 and 11. The reduction of bilirubin and ammonia were very significant (P < 0.01), whereas the changes of International Normalized Ratio (INR) were not significant. Also the modifications of albumin, total protein, sodium, potassium and calcium were not significant. In conclusion, four out of nine patients with PNF are alive without a second transplantation and were discharged after about 48 days; four out of nine underwent OLT, while one out of nine died; five out of six patients with DF are alive without a second transplantation, and they were discharged after an average time of 55.5 days, one out of six died; six out of nine patients with fulminant hepatitis underwent OLT and four of these are alive, while two died due to sepsis; three patients are alive without OLT. Four patients with AOCHF underwent OLT and are alive, three patients are alive and on a waiting list, two died while on a waiting list and one patient who experienced reactivation of HBV infection during chemotherapy for non-Hodgkin's lymphoma is alive. In spite of the limited numb...

Solid organ transplant patients are at a higher risk for poor CoronaVirus Disease‐2019 (COVID‐19)‐related outcomes and have been included as a priority group in the vaccination strategy worldwide. We assessed the safety and efficacy of a two‐dose vaccination cycle with mRNA‐based COVID‐19 vaccine (BNT162b2) among 82 kidney transplant outpatients followed in our center in Rome, Italy. After a median of 43 post‐vaccine days, a SARS‐CoV‐2 anti‐Spike seroprevalence of 52.4% (n = 43/82) was observed. No impact of the vaccination on antibody‐mediated rejection or graft function was observed, and no significant safety concerns were reported. Moreover, no de novo HLA‐donor‐specific antibodies (DSA) were detected during the follow‐up period. Only one patient with pre‐vaccination HLA‐DSA did not experience an increased intensity of the existing HLA‐DSA. During the follow‐up, only one infection (mild COVID‐19) was observed in a patient after receiving the first vaccine dose. According to the multivariable logistic regression analysis, lack of seroconversion after two‐dose vaccination independently associated with patient age ≥60 years (OR = 4.50; P = .02) and use of anti‐metabolite as an immunosuppressant drug (OR = 5.26; P = .004). Among younger patients not taking anti‐metabolites, the seroconversion rate was high (92.9%). Further larger studies are needed to assess the best COVID‐19 vaccination strategy in transplanted patients.

Pretransplant sCD30 is a more accurate predictor of AR when compared with PRA. These results support its use in the pretransplant work-up of kidney-graft recipients.
