Brief Summary

Pure red cell aplasia (PRCA) is a kind of anemia characterized by severe reticulocytopenia and obvious bone marrow erythroblastic cells decreased. Cyclosporine A and /or steroids are the first line therapy but some patients were refractory or intolerance to the treatment. The effects of the second line therapy are also not satisfactory and sometimes not available. The investigators aim to explore the efficacy and side-effect of sirolimus for newly diagnosed primary acquired PRCA.

Drug: Sirolimus

Cyclosporine A on newly diagnosed primary acquired PRCA

ACTIVE COMPARATOR

Cyclosporine A (CsA) efficiency on newly diagnosed primary acquired PRCA patients. CsA dosage: 4mg/kg QD. Medication time should last at least 6 months

Drug: Cyclosporine A

Interventions

Sirolimus treats in experimental group

Also known as: Sirolimus Tablets
