Transplant-Related Disorder

This study aims to evaluate the efficacy of prophylactic ruxolitinib in adult patients at intermediate-to-high risk of severe acute GvHD, as predicted by the daGOAT model.

The goal of this observational study is to establish risk factors for post-transplant in adult individuals with cirrhosis without diabetes undergoing liver transplant evaluation. The question being addressed is: can laboratory work, anthropometric tests, functional tests, imaging, and advanced measurements such as wrist actigraphy, continuous glucose monitoring, or oral glucose tolerance testing predict the development of diabetes after liver transplant? Participants will be asked to periodically participate in wearing a continuous glucose monitor and wrist actigraph and obtain an oral glucose tolerance test both before and after liver transplant.

This is a prospective observational study. The investigators plan to utilize this model as a tool for early classification and interrogate ANS function of transplant recipients.

The protocol is designed to provide access to patients to the Clinimacs® CD34 TCRαβ system to prepare cells for an unlabeled indication using an HLA-compatible related or unrelated donor for allogenic transplant.

This is a multicenter, open-label study in people aged 18 and older with relapsed or refractory acute myeloid leukemia. It has two parts. In Phase 2, we are testing three radiation dose levels of 131I-apamistamab combined with fludarabine and low-dose whole-body radiation before stem cell transplant to find the safest and most effective dose. In Phase 3, patients will be randomly assigned to receive either this treatment combination or a standard of care regimen before transplant. The main goal is to see if the new approach helps people live longer. Phase 2 will enroll about 60 people, and Phase 3 will enroll about 246 people.

Human cytomegalovirus (CMV) is a globally prevalent, human-specific herpesvirus characterised by a lifelong latency after primary infection, an often asymptomatic reactivation and affecting up to 100% of adults based on region and age. CMV reactivation has serious risks for immunocompromised patients, especially those undergoing allogeneic hematopoietic stem cell transplantation (HSCT). In these patients, CMV can lead to graft failure, multiorgan disease, increased risk of other infections, GVHD, post-transplant lymphoproliferative disorders, and higher transplant-related mortality (TRM). Although antiviral prophylaxis, CMV infection occurs in 38-80% of HSCT recipients, but current antiviral drugs are insufficiently effective and they are associated with adverse effects. Furthermore, treatment failure is due to the high genetic variability of CMV. The protective role of virus-specific antibodies remains under debate. Some studies suggest that high neutralizing antibody titers protect transplant recipients from CMV, while others highlight the importance of T-cell responses. However, recent animal studies showed that humoral immunity alone can prevent CMV reactivation, even without T or NK cells. In solid-organ transplant patients, antibody titers ≥480 have been linked to reduced infection, shorter treatment, and full protection from CMV disease. Although the use of anti-CMV immunoglobulin remains controversial, the IRCCS Burlo Garofolo has used it as post-transplant prophylaxis and second-line treatment for over a decade. The main objective of their study was to assess whether CMV-specific immunoglobulin prophylaxis reduces CMV incidence and severity in pediatric HSCT patients. Secondary goals included evaluating its effect on transplant outcomes and its efficacy across different ethnic groups. A population pharmacokinetic (POP/PK) study was also conducted to better understand the drug's distribution and elimination and to identify factors influencing its pharmacokinetics in patients.

The investigators aim to perform a randomized clinical trial to determine the optimal timing of hepatitis B vaccination after hematopoietic cell transplantation (HCT) through evaluating the immunity effect of two different vaccination schedules (initiated at 3 or 6 months after transplantation) in patients with different immune reconstitution status.

To assess the effectiveness of interventions including health monitoring and regular return follow-up reminders for patients with a high Composite Immune Risk Score.
