Predictive biomarkers and preventive strategies for PTLD: a turning point in viro-immunologic precision medicine?
Review in Transplant international : official journal of the European Society for Organ Transplantation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Post-transplant lymphoproliferative disorders (PTLD) represent a heterogeneous group of complications with rising complexity, particularly as EBV-negative forms are increasingly recognized in adult recipients. While early EBV-driven PTLD was historically monitored by viral load, this approach fails to detect EBV-negative disease and lacks specificity even in EBV-positive cases. Recent advances in tumor immunology, virology, and liquid biopsy technologies have led to the emergence of novel biomarkers that offer improved diagnostic precision. These include plasma soluble ZEBRA antigen, reflecting lytic EBV activation; EBV DNA methylation status, which may distinguish latent from benign viral replication; and LMP1 sequence variants that influence immune evasion through the NKG2A/HLA-E axis. For EBV-negative PTLD, circulating tumor DNA profiling has shown promise for early, non-invasive detection. These innovations are complemented by preventive strategies such as anti-CD20 therapy in high-risk EBV-seronegative transplant recipients and ongoing trials of EBV-targeted vaccines. However, such approaches remain limited to EBV-naïve patients. Moving forward, integrating viral, immune, and tumor-derived markers-alongside host genetic factors-may enable more personalized surveillance and preemptive interventions. This review outlines the evolving paradigm of PTLD monitoring and highlights key areas where viro-immunologic precision medicine may reshape clinical practice.
