Background Aims: In HLA-identical hematopoietic stem cell transplantation (HSCT), HLA-C1 group killer cell immunoglobulin-like receptor (KIR) ligands have been linked to graft-versus-host disease, whereas C2 homozygosity was associated with increased relapses. The differential impact of the recipients versus the donor's HLA-C KIR ligands cannot be determined in HLA-identical HSCT but may be elucidated in the haploidentical setting, in which HLA-C (including the HLA-C KIR ligand group) mismatching is frequently present.
Methods: We retrospectively investigated the effect of recipient versus donor C1 ligand content on survival and complications in post-transplant cyclophosphamide (PTCy)-based haploidentical HSCT (n = 170).
BK Polyomavirus and acute kidney injury in transplant recipients: signaling pathways and molecular mechanisms.

Acute kidney injury (AKI) is a condition that can result in changes in both urine production and creatinine levels in the bloodstream, complicating the treatment process and worsening outcomes for many hospitalized patients. BK polyomavirus (BKPyV), a member of the Polyomaviridae family, is prevalent in the population and remains latent in the body. It can reactivate in individuals with a compromised immune system, particularly post-kidney transplant, and can activate various transcription factors and immune mediators.

Introduction: Preclinical studies have shown that oxygen therapy can improve ischaemic brain tissue oxygen tension, reduce reperfusion injury after revascularisation, promote neuroregeneration and inhibit inflammatory responses potentially exerting a beneficial effect after endovascular treatment (EVT) in patients with acute ischaemic stroke (AIS). However, the optimal fraction of inspired oxygen (FiO) during EVT under general anaesthesia is currently unknown. Therefore, we are conducting a randomised controlled trial (RCT) to evaluate the impact of high-concentration oxygen vs low-concentration normobaric oxygen on early neurological function after EVT.

Cerebral venous sinus thrombosis is an uncommon sequela of low intracranial pressure, which may result from a lumbar puncture (LP). We describe a case of a patient in their 40s presenting with 48 hours of persistent headache following intrathecal administration of nusinersen for spinal muscular atrophy (SMA) type 3. There were no focal neurological signs or symptoms apart from baseline symmetrical proximal limb weakness attributed to SMA.

Background: Patients with non-functioning renal grafts constitute approximately 4% of patients with incident dialysis. Complete withdrawal of immunosuppression has been associated with a higher risk of HLA sensitization and renal graft intolerance syndrome (GIS).
Methods: We conducted a retrospective observational study of 63 patients with renal graft failure (from January 2012 to December 2022).
