Myelodysplastic Syndromes Clinical Trial
Official title:
TCR Vbeta Repertoire and PNH Clones in Children With Refractory Cytopenia (RC). An Open Nonrandomised Multi-Center Prospective Study
RATIONALE: Studying biopsy, bone marrow, and blood samples from patients with cytopenia that
did not respond to treatment may help doctors learn more about the disease and plan the best
treatment.
PURPOSE: This laboratory study is assessing immune function in young patients with cytopenia
that did not respond to treatment.
OBJECTIVES:
Primary
- To evaluate the value of TCR V beta repertoire analysis for the determination of
autoimmunity in refractory cytopenia (RC).
- To evaluate which immunophenotypic hematopoietic subclones are associated with
oligoclonal T-cell expansion in RC.
- To evaluate the presence of paroxysmal nocturnal hemoglobinuria (PNH) clones in RC.
Secondary
- To compare the molecular response with the hematologic response in patients with RC
after treatment with immunosuppressive therapy (IST).
- To compare the molecular response with human leukocyte histocompatability antigen (HLA)
expression in patients with RC after treatment with IST.
OUTLINE: This is an open-label, multicenter, nonrandomized, prospective study.
Patients undergo biopsy, bone marrow, and blood sample collection periodically for
immunological studies. Samples are analyzed for TCR V beta repertoire and paroxysmal
nocturnal hemoglobinuria (PNH) clone analysis via PCR heteroduplex analysis and
immunophenotyping of CD14, CD16 , CD55, CD59, and CD24 expression via flow cytometry.
