Chronic Graft-Versus-Host Disease
Conditions
Brief summary
This study is a single-center observational clinical study. Participants were enrolled as two cohorts of patients including discovery cohort and validation cohort. A total of consecutive 1000 patients receiving allo-HSCT in our center from 2021.01 to 2023.06 were retrospectively included as discovery cohort. A total of consecutive 500 recipients from 2023.06 to 2024.06 were retrospectively enrolled as validation cohort. Heparinized blood samples were collected prospectively at day +90 after HSCT and the onset of manifestations in patients with cGVHD or at matched time points in controls. Patients in the validation cohort also had samples drawn at approximately day +90. We used multiplex mass spectrometry with pooled plasma for biomarker discovery in comparing proteomic profiles between patients with and without chronic GVHD.
Interventions
OTHERDetection of Inflammatory Cytokine Levels in Peripheral Blood Serum
This study is expected to develop a comprehensive predictive model based on plasma mass spectrometry data and clinical information, significantly improving the accuracy of early cGVHD prediction. By conducting in-depth analysis of plasma samples from cGVHD patients using mass spectrometry (MS) technology and integrating clinical data, the goal is to identify a set of biomarkers that can accurately diagnose, predict disease progression, and assess prognosis. This approach aims to develop a clinically actionable tool for cGVHD diagnosis and prediction, enabling early detection and precise intervention. The model will provide clinicians with more precise diagnostic tools and treatment decision support, facilitating early detection and targeted treatment of cGVHD. Additionally, the findings of this study will offer new data to support further biological research on cGVHD mechanisms and provide a theoretical basis for future personalized medicine approaches.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To construct a diagnostic and predictive model for cGVHD | day +90 after HSCT | By analyzing plasma samples from cGVHD patients using mass spectrometry (MS) technology, the aim is to identify biomarkers associated with cGVHD. Additionally, the model will integrate clinical information (such as transplant type, HLA matching, aGVHD history, etc.) to develop a comprehensive predictive model that can accurately diagnose cGVHD and predict disease -severity. This model will help improve early-stage recognition of cGVHD, especially in cases where symptoms are non-specific or difficult to detect and provide clinical decision support. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To identify biomarkers associated with the prognosis of cGVHD | day +90 after HSCT | Through mass spectrometry analysis, this study will explore the relationship between biomarkers in plasma samples and the treatment response, and severity of cGVHD patients. The goal is to identify biomarkers closely linked to cGVHD prognosis, providing more accurate risk assessment and long-term prognostic prediction tools for patients. |
