Variation in Post-Transplant Cancer Incidence among Italian Kidney Transplant Recipients over a 25-Year Period.

This cohort study examined 25-year variations in cancer incidence among 11,418 Italian recipients of kidney transplantation (KT) from 17 Italian centers. Cancer incidence was examined over three periods (1997-2004; 2005-2012; and 2013-2021) by internal (Incidence rate ratio-IRR) and external (standardized incidence ratios-SIR) comparisons. Poisson regression was used to assess trends.

SARS-CoV-2 infection in dialysis and kidney transplant patients: immunological and serological response.

Background: Dialysis and kidney transplant patients with moderate-severe COVID-19 have a high mortality rate, around 30%, that is similar in the two populations, despite differences in their baseline characteristics. In these groups, the immunology of the disease has been poorly explored.

Methods: Thirty-two patients on dialysis or with kidney transplant and SARS-CoV-2 infection requiring hospitalization (COV group) were included in our study.

The impact of cancer on the risk of death with a functioning graft of Italian kidney transplant recipients.

This study assessed the impact of cancer on the risk of death with a functioning graft of kidney transplant (KT) recipients, as compared to corresponding recipients without cancer. A matched cohort study was conducted using data from a cohort of 13 245 individuals who had undergone KT in 17 Italian centers (1997-2017). Cases were defined as subjects diagnosed with any cancer after KT.

Mycophenolate mofetil versus azathioprine in kidney transplant recipients on steroid-free, low-dose cyclosporine immunosuppression (ATHENA): A pragmatic randomized trial.

Background: We compared protection of mycophenolate mofetil (MMF) and azathioprine (AZA) against acute cellular rejection (ACR) and chronic allograft nephropathy (CAN) in kidney transplant recipients on steroid-free, low-dose cyclosporine (CsA) microemulsion maintenance immunosuppression.

Methods And Findings: ATHENA, a pragmatic, prospective, multicenter trial conducted by 6 Italian transplant centers, compared the outcomes of 233 consenting recipients of a first deceased donor kidney transplant induced with low-dose thymoglobulin and basiliximab and randomized to MMF (750 mg twice/day, n = 119) or AZA (75 to 125 mg/day, n = 114) added-on maintenance low-dose CsA microemulsion and 1-week steroid. In patients without acute clinical or subclinical rejections, CsA dose was progressively halved.

and SARS-CoV-2 Co-Infection: A Common Feature in Transplant Recipients?

COVID-19 might potentially give rise to a more severe infection in solid organ transplant recipients due to their chronic immunosuppression. These patients are at a higher risk of developing concurrent or secondary bacterial and fungal infections. Co-infections can increase systemic inflammation influencing the prognosis and the severity of the disease, and can in turn lead to an increased need of mechanical ventilation, antibiotic therapy and to a higher mortality.

Kidney transplant patients with SARS-CoV-2 infection: The Brescia Renal COVID task force experience.

The outcome of kidney transplant patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is still unclear. Here we describe the clinical characteristics, disease outcome, and risk factors for acute respiratory distress syndrome (ARDS) and death of a cohort of 53 kidney transplant patients with coronavirus disease 2019 (COVID-19). Eight of 53 have been handled as outpatients because of mild disease, on average with immunosuppression reduction and the addition of hydroxychloroquine and azithromycin; no patients required admission, developed ARDS, or died.

A report from the Brescia Renal COVID Task Force on the clinical characteristics and short-term outcome of hemodialysis patients with SARS-CoV-2 infection.

The SARS-CoV-2 epidemic is pressuring healthcare systems worldwide. Disease outcomes in certain subgroups of patients are still scarce, and data are needed. Therefore, we describe here the experience of four dialysis centers of the Brescia Renal COVID Task Force.

Tocilizumab for the treatment of severe COVID-19 pneumonia with hyperinflammatory syndrome and acute respiratory failure: A single center study of 100 patients in Brescia, Italy.

A hyperinflammatory syndrome (HIS) may cause a life-threatening acute respiratory distress syndrome (ARDS) in patients with COVID-19 pneumonia. A prospective series of 100 consecutive patients admitted to the Spedali Civili University Hospital in Brescia (Italy) between March 9th and March 20th with confirmed COVID-19 pneumonia and ARDS requiring ventilatory support was analyzed to determine whether intravenous administration of tocilizumab (TCZ), a monoclonal antibody that targets the interleukin 6 (IL-6) receptor, was associated with improved outcome. Tocilizumab was administered at a dosage of 8 mg/kg by two consecutive intravenous infusions 12 h apart.

A single center observational study of the clinical characteristics and short-term outcome of 20 kidney transplant patients admitted for SARS-CoV2 pneumonia.

The outcome of SARS-CoV2 infection in patients who have received a kidney allograft and are being treated with immunosuppression is unclear. We describe 20 kidney transplant recipients (median age 59 years [inter quartile range 51-64 years], median age of transplant 13 years [9-20 years], baseline eGFR 36.5 [23-47.

Management of Patients on Dialysis and With Kidney Transplantation During the SARS-CoV-2 (COVID-19) Pandemic in Brescia, Italy.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also known as coronavirus disease (COVID-19), is a major pandemic challenging health care systems around the world. The optimal management of patients infected with COVID-19 is still unclear, although the consensus is moving toward the need of a biphasic approach. During the first phase of the disease (from onset of the symptoms up to 7-10 days) viral-induced effects are prominent, with the opportunity to institute antiviral therapy.

[Managing patients in dialysis and with kidney transplant infected with Covid-19].

We are in the midst of a health emergency that is totally new for us all and that requires a concerted effort, especially when it comes to safeguarding patients on hemodialysis, and kidney transplant recipients. Brescia is currently a very active cluster of infections (2918 cases on the 17/03/2020), second only to Bergamo. The way our structure is organised has allowed us to treat nephropathic patients directly within the Nephrology Unit, following of course a great deal of reshuffling; at the moment, we are treating 21 transplanted patients and 17 on hemodialysis.

Effectiveness of kidney transplantation in HIV-infected recipients under combination antiretroviral therapy: a single-cohort experience (Brescia, Northern Italy).

Purpose: Kidney transplantation was recently introduced for the treatment of end stage renal disease (ESRD) in HIV-infected patients. We report the results of the first 28 procedures at our centre.

Methods: A retrospective study was conducted on HIV-infected patients evaluated for kidney transplantation between January 2005 and October 2016.

West Nile virus outbreak in the Lombardy region, northern Italy, summer 2013.

In the summer of 2013, an outbreak of West Nile virus (WNV) infection occurred in the Lombardy, a region of northern Italy to the west of districts affected by WNV in previous years. Eighteen cases of human WNV infection were diagnosed--10 cases of acute WNV neuroinvasive disease and eight of WNV fever. In the same period, WNV was detected in birds (one crow) in horses (11 cases) and from mosquitoes (six pools).

Kidney transplantation in HIV-positive patients treated with a steroid-free immunosuppressive regimen.

One of the main concerns associated with renal transplantation in HIV-infected patients is the high risk of acute rejection, which makes physicians reluctant to use steroid-free immunosuppressive therapy in this subset of patients. However, steroid therapy increases cardiovascular morbidity and mortality. The aim of this study was to define the efficacy of a steroid-sparing regimen in HIV-infected renal transplant recipients.

[Kidney transplant in HBsAg+, HCV+ or HIV+ patients].

Hepatitis B and C virus infections are relatively common among patients with end-stage kidney disease on dialysis and kidney transplant recipients. These conditions are associated with increased morbidity and mortality after kidney transplant. Careful management of the transplant candidate by viral replication assessment and liver biopsy allows to achieve excellent kidney transplant results in these patients, also thanks to the antiviral therapies available today including pretransplant interferon for hepatitis C and nucleoside analogue reverse transcriptase inhibitors for hepatitis B.

[Kidney transplant in patients with HIV infection].

Until recently, human immunodeficiency virus (HIV) infection was an absolute contraindication to solid organ transplantation because it was feared that the anti-rejection therapy could result in accelerated HIV disease. At the end of the 1990s it became clear that HIV infection, once deemed a fatal disease, could be effectively turned into a chronic condition by the use of highly active antiretroviral therapy. Since then, the mortality rate from opportunistic infections has decreased dramatically, while liver and renal insufficiency have become the major causes of morbidity and mortality in these patients in the long term.

Tacrolimus versus cyclosporine for early steroid withdrawal after renal transplantation.

Introduction: This study compares cyclosporine (CsA) with tacrolimus (Tac) in preventing acute rejection (AR) after steroid withdrawal (SW) 5 days after renal transplantation (Tx).

Methods: The data were collected from 2 prospective sequential studies carried out from February 2002 to May 2006. Forty-nine patients received CsA, 56 patients Tac.

The number of circulating recent thymic emigrants is severely reduced 1 year after a single dose of alemtuzumab in renal transplant recipients.

To better understand the kinetics of the delayed reconstitution of peripheral CD4+ T-cells after depletion with a single administration of alemtuzumab (AL) for renal transplantation, we evaluated in these patients the percentage and absolute number of recent thymic emigrants (RTEs) CD4+ T cells, together with naive and memory subsets, defined by the analysis of CD31, CD45RA and CCR7 expression, and compared with patients treated with a nondepleting protocol based on basiliximab, and with healthy controls. In AL-treated patients, the number of circulating CD4+ T cells was greatly reduced 1 year after the infusion (P < 0.01), but the proportions of central memory, effector memory and terminally differentiated effector memory subsets among CD4+ cells were significantly increased.

Early (fifth day) vs. late (sixth month) steroid withdrawal in renal transplant recipients treated with Neoral(®) plus Rapamune(®): four-yr results of a randomized monocenter study.

The most advisable timing for steroid withdrawal (CSWD) after renal transplantation (Tx) is still an open issue. This randomized study has compared early CSWD (at day 5) with late (at month 6) in patients under Neoral + Sirolimus. The primary end point was the percentage of success in CSWD at month 48.

Steroid withdrawal five days after renal transplantation allows for the prevention of wound-healing complications associated with sirolimus therapy.

Background: Sirolimus (SRL) can increase the risk of wound complications. In this study, we investigated the impact of steroids when added to SRL, in this side effect.

Methods: One hundred and forty-eight patients entered prospective studies comparing early (fifth day) with late (sixth month) steroid withdrawal.

Patient mortality after graft failure reduces kidney transplant patient survival only in the long term: an "intention to treat" analysis.

The benefits of kidney transplantation over dialysis on patient survival have been demonstrated without considering the outcomes of patients with graft loss. To determine whether mortality after graft failure reduced the transplantation advantage in patient survival, we retrospectively reviewed the outcomes of 918 first-deceased renal transplant recipients from May 1979 to August 2005. Patient survivals were 88% and 72% at 10 and 20 years; cancer (26%) and cardiovascular disease (25%) were the major causes of death.

Transplantation outcome in patients on PD and HD.

In the past, peritoneal dialysis (PD) has been considered a second choice dialysis modality for many aspects and that negative attitude has been extended also to possible negative effects on renal transplantation. In the last years, many papers have faced the question whether PD could attain similar results in renal transplantation as hemodialysis and there is sufficient evidence to answer that question. On the short time after transplantation, patients coming PD have lower prevalence of delayed graft function than hemodialysis patients, but higher prevalence of renal vascular thrombosis, above all in children.
