Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Autoimmune hemolytic anemia (AIHA) is a rare and heterogeneous disorder characterized by the destruction of red blood cells through warm or cold antibodies. Glucocorticoid (combined with rituximab) is the first-line treatment. However, the recurrence rate is very high and some patients may not respond to steroids. Second-line therapies include cyclosporine A (CsA), cyclophosphamide, rituximab, azathioprine, and even splenectomy. Our previous study of sirolimus in refractory/relapsed AIHA and ES found an effective rate of 80%. Therefore, the investigators plan to explore the efficacy and safety of sirolimus in the treatment of refractory/relapsed wAIHA.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Based on the optimal autoantibody-RBC reactivity temperatures, AIHA is classified into warm type, cold type, and mixed type. AIHA can be further classified into primary or secondary in nature. Glucocorticoid (combined with rituximab) is the first-line treatment. However, the recurrence rate is very high and some patients may not respond to steroids. Second-line therapies include cyclosporine A (CsA), cyclophosphamide, rituximab, azathioprine, and even splenectomy. The refractory/relapsed wAIHA patients have increased cardiovascular events, increased opportunities for infections, decreased quality of life, and even death. A prospective multi-institutional trial in autoimmune cytopenia found that 8 of 10 patients with AIHA and Evans syndrome respond to sirolimus. Our previous study of sirolimus in refractory/relapsed AIHA and ES also found an effective rate of approximately 80%. Since sirolimus is cheap and accessible, our findings may reduce the economic burden of patients and be a guide on the selection of second-line treatment drugs in refractory/relapsed wAIHA and Evans syndrome.

Sirolimus on refractory/relapsed wAIHA

A prospective research of the sirolimus efficiency on refractory/relapsed primary wAIHA patients. Sirolimus dosage: 1-3 mg/d with plasma concentration 4-15ng/mL. Medication time should last at least 6 months. After reaching the optimal response, responders continue to use sirolimus for 1 year, and then gradually reduce the dosage.
