Assessment of the use of immunosuppressants combined with cord blood for severe aplastic anemia.

Background: The objective of this study was two-fold: 1) to investigate the changes of cytokines concentration in relation to severe aplastic anemia (SAA) when treated with immunosuppressants combined with cord blood (IS + CBI). and 2) to assess the curative effect of umbilical cord blood chimerism engraftment.

Methods: We selected 43 patients with SAA all treated with IS + CBI (newly diagnosed group).

Mechanism of immunosuppressants combined with cord blood for severe aplastic anemia.

This study aims to explore the mechanism of immunosuppressants combined with cord blood (IS + CBI) for severe aplastic anemia. Selecting 30 patients with SAA and all treated with IS + CBI (newly diagnosed group). 23 patients who were treated effectively (effective group) while 7 cases were treated invalidly (invalid group).

[Preliminary study of multivariable model in predicting response to immunosuppressive therapy in patients with aplastic anemia].

Objective: To evaluate the potential usefulness of a multivariable model in predicting the response to immunosuppressive therapy (IST) in patients with aplastic anemia (AA), and its application to the clinical practice.

Methods: PB T cells subpopulation and BM T cells intracellular IFN-gamma and IL-4 were serially analyzed by flow cytometry (FCM) before and during treatment. HLA-DRB1 * 1501 phenotype was analyzed by PCR-SSP.

[Clinical implications of combined measurement bone marrow T cells intracellular IFNgamma and HLA-DRB1*1501 measurement in predicting the response to immunosuppressive therapy for aplastic anemia].

Objective: To evaluate the clinical implication of combined measurement of bone marrow (BM) T lymphocyte intracellular IFNgamma with HLA-DRB1*1501 in predicting the response to immunosuppressive therapy (IST) in patients with aplastic anemia (AA).

Methods: Enrolled into the present study were 51 idiopathic AA patients treated with cyclosporine A (CsA) based IST. BM CD(8)(+) T lymphocyte intracellular IFNgamma was determined with flow cytometry and HLA-DRB1*1501 detected with PCR-sequence specific primer before treatment.
