Allorecognition Unveiled: Integrating Recent Breakthroughs Into the Current Paradigm.

Transpl Int

November 2024

Centre International de Recherche en Infectiologie, INSERM U1111, Université Claude Bernard Lyon I, CNRS UMR5308, Ecole Normale Supérieure de Lyon, University Lyon, Lyon, France.

In transplantation, genetic differences between donor and recipient trigger immune responses that cause graft rejection. Allorecognition, the process by which the immune system discriminates allogeneic grafts, targets major histocompatibility complex (MHC) and minor histocompatibility antigens. Historically, it was believed that allorecognition was solely mediated by the recipient's adaptive immune system recognizing donor-specific alloantigens.

Kidney transplant recipients (KTRs) are highly vulnerable to COVID-19. An intensified scheme of vaccination offers short-term protection to the 50%-75% of KTRs able to develop a germinal center reaction, required for the generation of neutralizing titers of antibodies (NAbs). However, the duration of this vaccinal protection is unknown.

Carotid web: Pathophysiology, diagnostic, and therapeutic options. A narrative review.

Vasc Med

October 2024

Service de Chirurgie Vasculaire et Endovasculaire, Hôpital Louis Pradel, Hospices Civils de Lyon, Bron, France.

Article Synopsis
  • A carotid web (CaWeb) is a rare fibrous tissue growth in the carotid bulb, often leading to ischemic strokes in younger individuals, especially young women.
  • Recent reviews reveal that traditional diagnostic criteria may miss CaWebs since many patients show less than 50% stenosis on ultrasound, complicating their detection and management.
  • Current treatment approaches for symptomatic CaWebs focus on procedures like endarterectomy or stenting, but there are still no standardized guidelines for handling asymptomatic cases, making ongoing research crucial.

Article Synopsis
  • The study explored how increased oxygen extraction fraction (OEF) affects the recovery of diffusion-weighted imaging (DWI) lesions in stroke patients who underwent thrombectomy after acute ischemic events.
  • It analyzed data from the HIBISCUS-STROKE cohort, focusing on DWI and perfusion magnetic resonance imaging results to understand the relationship between OEF levels and changes in ischemic lesion volume.
  • Results showed that patients with increased OEF within their DWI lesions experienced a significant reduction in lesion volume compared to those without increased OEF, suggesting that higher OEF may be a positive indicator for recovery post-thrombectomy.

Article Synopsis
  • The study investigates mineral bone disorder in patients with chronic kidney disease after kidney transplantation, focusing on bone biomarkers and microarchitecture changes before and 6 months after the surgery.
  • A subgroup of patients aged 10 to 18 who underwent their first kidney transplant was compared to healthy controls, revealing initially higher bone densities but notable declines in trabecular microarchitecture at the radius six months post-transplant.
  • Despite some improvements in bone health, many patients persisted with metabolic issues like acidosis and elevated parathyroid hormone levels after the transplant, indicating ongoing bone metabolism concerns.

Article Synopsis
  • A study called IMADGIST assessed whether extending adjuvant imatinib treatment for an additional three years (totaling six years) improved disease-free survival in patients with high-risk localized gastrointestinal stromal tumors (GIST) who had already received three years of treatment after surgery.
  • Conducted across 14 centers, the trial included 136 patients with varied risks of tumor recurrence, finding that those treated for six years had significantly better disease-free survival compared to those who stopped after three years.
  • Although there was no significant difference in overall survival, time to imatinib resistance, or quality of life between the two groups, the results suggest that extending treatment can effectively lower relapse rates with
