Objectives: Hepatitis delta virus infection poses a significant challenge in solid-organ transplant recipients due to its aggressive nature and limited therapeutic options. Bulevirtide is a novel antiviral agent approved by the European Medicines Agency in 2020 for the treatment of hepatitis delta virus infection, but limited data are available on its use in solid-organ transplant recipients.

Materials And Methods: We present a case report of a 42-year-old male kidney transplant patient with coinfection of hepatitis B virus and hepatitis delta virus who was treated with bulevirtide over a 6-month period.

Article Synopsis
  • Pre-exposure prophylaxis with Tixagevimab/Cilgavimab has effectively reduced COVID-19 risks in immunocompromised patients, but its efficacy is limited against the Kraken variant (XBB.1.5).
  • A study involving kidney transplant patients on this treatment showed only one asymptomatic infection during a six-month follow-up, with no hospitalizations or COVID-related deaths.
  • The results suggest Tixagevimab/Cilgavimab may still be a beneficial preventive option for immunocompromised individuals, underlining the need for further clinical research on this topic.

Identification of early signatures of immune rejection represents a key challenge in the clinical management of kidney transplant. To address such an issue, we enrolled 53 kidney transplant recipients without signs of graft rejection, no infectious episodes and no change in the immunosuppressive regimen in the last 6 months. An extensive immune profile revealed increased activation of the T cells, a decreased amount and growth ability of the Treg and a higher level of the T regulatory T cell subset, described by us as involved in the preferential control of cytotoxic T lymphocytes.

SARS-CoV-2 vaccination is the standard of care for the prevention of COVID-19 disease. Although vaccination triggers both humoral and cellular immune response, COVID-19 vaccination efficacy is currently evaluated by measuring antibodies only, whereas adaptative cellular immunity is unexplored. Our aim is to test humoral and cell-mediated response after three doses of BNT162b vaccine in two cohorts of fragile patients: Common Variable Immunodeficiency (CVID) patients and Kidney Transplant Recipients (KTR) patients compared to healthy donors.

Vaccination against SARS-CoV2 represents a key weapon to prevent COVID-19, but lower response rates to vaccination have frequently been reported in solid organ transplant recipients. The aim of our study was to evaluate the rate of seroconversion to SARS-CoV-2 mRNA vaccines in a cohort of kidney transplant recipients and the potential role of the different immunosuppressive regimens. We conducted an observational retrospective cohort study in kidney transplant patients vaccinated for COVID-19.

Introduction: In solid organ transplant recipients, COVID-19 is associated with a poor prognosis because of immunosuppression. Some studies suggest a potential therapeutic role of mammalian Target of Rapamycin (mTOR) inhibitors in SARS-CoV-2 infection. This study aimed to assess the impact of mTOR employment on the evolution and outcome of SARS-CoV-2 infection in solid organ transplant recipients.

Background: In kidney transplant recipients (KTR), the end-stage kidney disease (ESKD) risk dependent on the risk factors acting in native chronic kidney disease (CKD) remains undefined.

Methods: We compared risk and determinants of ESKD between 757 adult KTR and 1940 patients with native CKD before and after propensity-score (PS) analysis matched for unmodifiable risk factors [(age, sex, diabetes, cardiovascular disease and estimated glomerular filtration rate (eGFR)].

Results: In unmatched cohorts, eGFR was lower in CKD versus KTR (45.

Background: Rocuronium can be used in patients with severe renal failure (creatinine clearance <30 mL/min), but the duration of muscle relaxation is longer and results in an increased risk of postoperative residual neuromuscular block. Rocuronium can be antagonized by sugammadex, but the elimination of the complex they make (rocuronium-sugammadex complex) varies according to the renal function. Two case reports/series have reported the use of rocuronium-sugammadex complex during renal transplantation.

Background: Tacrolimus (TCR) is an immunosuppressive drug used by oral administration. Intravenous (IV) TCR administration is required under conditions of gastrointestinal diseases or abdominal surgery at the onset of paralytic ileus. The infusion formulation needs a large dilution and therefore a careful technical management during continuous infusion by 24 h and may determine anaphylaxis, cardiac arrhythmia, QT prolongation and torsades de pointes.

Purpose: The aim of this study was to determine the prevalence of nonadherence in a cohort of renal transplant recipients (RTRs) and to evaluate prospectively whether more intense clinical surveillance and reduced pill number enhanced adherence.

Patients And Methods: The study was carried out in 310 stable RTRs in whom adherence, life satisfaction, and transplant care were evaluated by specific questionnaires (time 0). The patients under tacrolimus (TAC; bis in die [BID]) were then shifted to once-daily TAC (D-TAC) to reduce their pill burden (Shift group) and were followed up for 6 months to reevaluate the same parameters.

Background And Objective: Bacterial infections are common complications after organ transplantation. Fluoroquinolones are frequently used for treatment because of their broad spectrum of activity; but some of them, such as ciprofloxacin and norfloxacin, are reported to increase blood concentration of ciclosporin because they are metabolised by the liver through the same enzymatic pathway, the cytochrome P450 system. This study was performed to establish whether levofloxacin, a more recent fluoroquinolone that undergoes limited hepatic metabolism, interferes with metabolism and excretion of either ciclosporin microemulsion or tacrolimus.
