Brief summary

wAIHA or EVANS syndrome: Linpriril 40mg, oral, once daily. The therapeutic effect will be evaluated after 4 weeks. If the therapeutic effect does not reach the PR, the dose will be increased to 60mg once a day. After continuing to take it for 4 weeks, the therapeutic effect will be evaluated again. If the PR is not reached, it can be increased to 80mg. If the PR is still not reached after continuing to take it for 4 weeks, it will be discontinued (for a total of 12 weeks). The initial dose is 40mg, taken orally once a day. If the therapeutic effect reaches PR or above after 4 weeks, continue taking this dose. The evaluation is the same as before every 4 weeks. The research period was 12 weeks. The duration of continuous treatment for effective patients is determined by the researchers, and the dosage of the drug can be reduced or increased. cAIHA: Linpriril 80mg, oral administration, once daily. The therapeutic effect was evaluated every 4 weeks. The research period was 12 weeks. The treatment was discontinued if the therapeutic effect did not reach the PR within 12 weeks. The duration of continuous treatment for effective patients is determined by the researchers, and the dosage of the drug can be reduced or increased.

Inclusion criteria

(1)Age ≥18 years old (2) Clearly diagnosed wAIHA or EVANS syndrome, cAIHA, primary or secondary connective tissue diseases. If it is secondary, there are no indications for the treatment of connective tissue diseases involving other systems. (3) Patients who relapse or are refractory after at least two lines of treatment (previous treatments include glucocorticoids, CD20 monoclonal antibodies or at least two other immunosuppressants). Refractory is defined as the failure to achieve partial remission after 3 months of stable dose treatment with immunosuppressants. (4) hb≤100 g / L (5) Those with complete clinical data, high treatment compliance, and those who have signed the informed consent form; (6) If glucocorticoids are being taken, they should be discontinued or the minimum maintenance dose has been taken for at least two weeks, and the minimum maintenance dose (≤15mg/day) should be continued subsequently (7) The infusion of CD20 monoclonal antibody should be at least 3 months or more. If the stable dose of immunosuppressants such as cyclosporine and sirolimus has been taken for at least 3 months, they should be discontinued upon enrollment.

Exclusion criteria

1. Those with incomplete functions of organs such as the heart, liver and lungs; Patients with acute renal insufficiency 2.
