Identification of Plasma Biomarkers for Early Diagnosis of Transplant-associated Thrombotic Microangiopathy

Recruiting now

Conditions studied: Thrombotic Microangiopathies, Hematopoietic Stem Cell Transplantation

In brief

The goal of this clinical trial is to learn about plasma biomarkers of diagnosed transplant-associated thrombotic microangiopathy (TA-TMA) in patients undergoing transplantation. The main questions it aims to answer are: whether there are molecules that can accurately diagnose and predict TA-TMA; whether the current biomarkers related to TA-TMA can well predict the occurrence and survival of TA-TMA in adult patients with malignant hematopoietic diseases, for example, acute leukemia. Participants will receive laboratory tests of peripheral blood and urine specimens related to TA-TMA at regular times after transplantation.

Who can join

Age: 14 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

1. Diagnosis of a hematologic disease (e.g., leukemia, myelodysplastic syndromes,lymphoma) confirmed by histology or other appropriate diagnostic methods.
2. undergoing allo-HSCT
3. Age 14 years or older
4.Informed consent must be signed before the start of the study. For participants aged 18 and above, the informed consent should be signed by the patient or their immediate family member. Considering the patient's condition, if it is not favorable for the patient to sign, the informed consent may be signed by a legal guardian or immediate family member of the patient.

You may not qualify if…

1. Missing or lost follow-up of key clinical data
2. failure to collect plasma samples at specific time points after transplantation
3. Plasma sample collection time later than the onset date of TMA
4. TMA occurrence time later than 180 days after transplantation
