Conditions
Summary
Hematological diseases are disorders of the blood and hematopoietic organs. The current hematological cohorts are mostly based on single-center or multi-center cases, or cohorts with limited sample size in China. There is a lack of comprehensive and large-scale prospective cohort studies in hematology. The objectives of this study are to investigate the incidence and risk factors of autoimmune hemolytic anemia (AIHA) and to analyze the treatment effectiveness, patient prognosis and healthcare costs in China. 1. Analyze the demographic and clinical characteristics of patients with AIHA, including sex, age, disease severity, and other relevant factors. 2. Examine disease features of AIHA patients, such as biochemical and hematological indicators 3. Assess treatment patterns and real-world effectiveness in AIHA patients. 4. Evaluate clinical outcomes, including hematologic response, relapse, and mortality 5. Investigate long-term prognosis, including post-discontinuation outcomes and health-related quality of life.
