Aplastic Anemia Life-Course Cohort Study (TRACE-AA)
A Longitudinal Cohort Study of Aplastic Anemia Across the Disease Course
To establish a longitudinal cohort spanning the entire care continuum of acquired aplastic anemia (AA), from diagnosis and treatment through long-term follow-up, integrating routinely collected clinical data with biospecimens obtained in accordance with applicable ethical and regulatory requirements. The cohort will support observational studies of the natural history of AA; treatment effectiveness and safety; the evolution of clonal hematopoiesis and clonal T-cell populations; immune reconstitution following immunosuppressive therapy (IST); the incidence of platelet transfusion refractoriness and its association with response to IST; and hematopoietic and immune reconstitution after transplantation. Ultimately, the cohort aims to generate real-world evidence to inform clinical practice and reduce the burden of AA.

Hematologic response
Tidsramme: Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.
|
Hematologic response contains improvements in hemoglobin level, platelet count and neutrophil count. |
Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.

|
Clonal evolution
Tidsramme: Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.
|
Progression to paroxysmal nocturnal hemoglobinuria, myelodysplastic syndrome, or acute myeloid leukemia. |
Assessments will be conducted at baseline, 6 months, 12 months, and 24 months after treatment, as well as at study completion, with an average interval of approximately 1 year.
|
|
Treatment related adverse events
Tidsramme: Within 10 years after allo-HSCT; within 6 months after IST
|
The main treatment modalities include allogeneic hematopoietic stem cell transplantation (allo-HSCT) and intensive immunosuppressive therapy (IST). Use Common Terminology Criteria for Adverse Events (CTCAE) Version 6 to assess the adverse event |
Within 10 years after allo-HSCT; within 6 months after IST
