Objective:
To explore the immune tolerance induction (ITI) in a case of severe hemophilia B patient with inhibitor.
Methods:
The F Ⅸ∶C was detected using a one-stage method and FIX inhibitor was assayed using Bethesda method. ITI was performed with prothrombin complex concentrates (PCC) in combination with rituximab.
Results:
His past exposure days (ED) with PCC were 20 ED and his peak FⅨ inhibitor titer was 56 BU/ml. When his FIX inhibitor titer decreased to 10.4 BU/ml in Nov. 2015 and after receiving the informed consent from his parents, ITI was started. PCC with low dose rituximab successfully eradicated the high titer inhibitor within 17 months. There was no anaphylaxis, thrombotic event and infection.
Conclusion
This is the first case report for successful immune tolerance induction therapy in Chinese hemophilia B patient. ITI using PCC combined with rituximab is an effective choice to induce immune tolerance of hemophilia B with inhibitor.

OBJECTIVETo deepen the understanding of clinical manifestations and treatment of patients with positive lupus anticoagulant (LAC).
METHODSThe clinical data of 2 patients were analyzed and related literature were reviewed.
RESULTSCase 1, a 31-year-old female, diagnosed as lupus anticoagulant positive, secondary to undifferentiated connective tissue disease, was presented with menorrhagia and thrombocytopenia. Anti-nuclear antibody (ANA) was positive 1:1000 (homogeneous type) with anti-double stranded DNA positive, and dRVVT LA1/LA2 was 3.4. Coagulation function was alleviated after treatment with glucocorticoid and total glucosides of paeony. Case 2, a 59-year-old female was presented with gingival bleeding, hematuria with the level of F II:C 13%. dRVVT LA1/LA2 was 2.0. Anti-nuclear antibody (ANA) was positive 1:1000 (type of cytoplasmic granule), anti-double stranded DNA was positive. The patient was diagnosed as hypoprothrombinemia-lupus anticoagulant syndrome (LAHS) and acquired coagulation factor deficiency. The signs of hemorrhage were alleviated after treatment with methylprednisolone 40 mg/day and cyclophosphamide, while the level of F II:C was below normal.
CONCLUSIONSymptoms of patients with positive LAC are variable. The diagnosis relies on history of disease and laboratory test. Currently, there is no standardized treatment. Cases of LAHS should be thoroughly investigated for any known causes and related disorder.

Objective:
To evaluate the efficacy and safety of a domestic human plasma derived coagulation Factor Ⅸ concentrate (pd-FⅨ) in patients with hemophilia B.
Methods:
The study was a multicenter, open-label and single-arm study. The efficacy of pd-F Ⅸ was evaluated by objective performance criteria. The doses of pd-FⅨ were calculated according to the bleeding symptom and disease severity. The infusion efficiency of pd-FⅨ and improvement of bleeding symptoms were measured at 30 minutes and (24±4) h after the first infusion, respectively. Adverse events were recorded. Viral infection and FⅨ inhibitor were detected 90 d after the first infusion.
Results:
All 36 subjects with hemophilia B were enrolled in the study. The median age of these patients was 31 years old and the median injection doses were 4 (1-17) times. The hemostatic effect of 27/36 (75.00%) and 9/36 (25.00%) acute bleeding events were rated as "excellent" and "better" , respectively. The recovery rate was 111.92% (65.55%-194.28%) at 30 minutes after infusion of FⅨ. There was no adverse event related to FⅨ. No reactivation of HBV, HCV or HIV and FⅨ inhibitor was detected at 90-104 d after the first FⅨ infusion.
Conclusion:
This domestically made human plasma derived FⅨ concentrate is safe and effective in the treatment of acute bleeding in patients with hemophilia B.
