Plain-language summary
Thrombotic Microangiopathy (TMA) Associated with Allogeneic Hematopoietic Stem Cell Transplantation (HSCT) is a serious complication that is associated with increased morbidity, related to multiple organ failure, with increased mortality in transplant patients. The incidence and evolution of TMA, especially in the adult population, is unclear due to the lack of early systematic screening and clear criteria for its diagnosis. For this reason, we designed this protocol to study the incidence and evolution of TMA Associated with allogeneic HSCT in adult patients from Argentina.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult patients (≥ 18 years) undergoing allogeneic HSCT in specialized centers that, as part of their usual follow-up protocol, carry out basic screening (laboratory/clinical) for TMA and in which patients consent (within the general transplant consent), to have their data used in observational studies.
* Patients with ≥ 3/laboratory/clinical diagnostic markers of TMA in two consecutive assessments within 14 days, namely: 1-Elevated Schistocytes in peripheral blood; 2-LDH above the upper normal limit; 3-De novo thrombocytopenia or requirement for platelet transfusion; 4-De novo anemia or requirement for red blood cell transfusion; 5-High blood pressure (≥140/90); 6-Protein/creatinine ratio \> 1mg/mg or proteinuria ≥ 30mg/dl in a random sample).
* Patients with suspected/diagnosed TMA who have signed the specific consent for the study.
Exclusion Criteria:
* Participation in an interventional treatment study of any therapy for TMA.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
