Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Engraftment rate and transplant related mortality | 365 days | engraftment rate will be evaluated by leukocyte counts in peripheral blood . Definition of engraftment: \>500 neutrophiles/µl blood. Transplant related mortality will be evaluated at day 100 and day 365 post transplant |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Graft versus Host disease and speed of immune reconstitution | 365 days | Incidence of acute and chronic GvHD will be evaluated according to Glucksberg criteria. Immune recovery will be evaluated by flow cytometry. Percentages and numbers of T, B and NK cells will be measured weekly until day 100, afterwards on day 180 and 365. |
