入选标准
- •Patients with PNH aged 18 years or older who started eculizumab treatment in accordance with drug label between 2012 and January 31st,
- •(However, patients who have received eculizumab as part of a clinical trial or an expanded access program/compassionate use program prior to 2012 are also eligible.)
- •Patients who are vaccinated against Neisseria meningitidis at least 2 weeks prior to starting eculizumab treatment. Patients who have been treated with appropriate prophylactic antibiotic therapy for 2 weeks after vaccination if they received eculizumab within 2 weeks after the vaccination.
排除标准
- •Pediatric patients with PNH aged under 18 years
- •Patients with hypersensitivity to the active ingredients of eculizumab, murine protein, or other components
- •Patients with untreated severe meningococcal (Neisseria meningitidis) infection
- •Patients who received other complement inhibitors for PNH before or during eculizumab treatment
结局指标
主要结局
Severity of anemia
时间窗: Before the administration, at 6, 12, 24 months after the start of the treatment and every and 12 months thereafter
Hb levels will be compared to identify the severity of anemia.
The Improvement/occurrence of complications and related clinical symptoms before and after eculizumab treatment
时间窗: 6 months before eculizumab administration to the end of the administration (It is up to subject's treatment period. Through study completion, an average of 51months)
The major complications due to PNH include thromboembolism, pulmonary hypertension, renal failure, and smooth muscle spasm, and their occurrence will be determined by the investigator. In addition, PNH-related symptoms (fatigue, anemia, dysphagia, shortness of breath/dyspnea, chest pain, abdominal pain, erectile dysfunction, hemoglobinuria, others) before and after eculizumab administration will be compared.
Effectiveness Evaluation at Last Follow-Up
时间窗: At the last follow-up (At the time of data collection retrospectively)
The investigator will perform the final evaluation of the efficacy for entire observation period based on the collected data. The investigator will comprehensively judge and evaluate the decrease of hemolysis occurrence, the improvement and occurrence of complications, and the severity of anemia, etc.
Decrease of hemolysis after eculizumab treatment
时间窗: The results of LDH tests performed before eculizumab treatment, at 6, 12, 24 months after the start of eculizumab treatment, and every 12 months thereafter will be collected.
The change in LDH levels before and after eculizumab treatment will be compared to determine whether hemolysis decreased after the treatment.
The required Unit of pRBC transfusion before and after eculizumab treatment
时间窗: From 1 year before the treatment to the end of the administration (It is up to subject's treatment period. Through study completion, an average of 51months)
