RESUMEN
Objective To review the pathogenesis and research prospects in AA.[Methods] In this paper, we summarize the imbalance mechanism of Th1/Th2, and the relationship of fol icular helper T cells(Tfh),Thl7, Th9 ,Th22 with aplastic anemia. [Results]The imbalance of Th1/Th2 cells leads to bone marrow failure. Immunosuppressive therapy can inhibit Th1 cell, restore the balance. The pathogenesis of Tfh, Thl7, Th9 and Th22 is closely correlated with AA. [Conclusion] AA pathogenesis is complex, CD4+cellsubsets is related to the occurrence and development of AA. Detect the levels of immune cells in the serum of patients is beneficial for diagnosis and treatment of AA.
RESUMEN
Hematologic disorders are very common in Systmic lupus erythematosus [SLE].First presentation of SLE with severe aplastic anemia [SAA] is extremely rare. We report a patient with the diagnosis of secondary SAA associated with SLE. Conventional therapy was not effective. She received Rituximab [RTX] and Antithymocyte globulin [ATG] therapy, her response was satisfactory finally. Her hematologic parameters were within normal ranges until last follow-up, eight months and six months after therapy was initiated with RTX and ATG, respectively. This is the first time RTX and ATG were successfully used in the treatment of SAA secondary to SLE
