Abstract
Hemophilia B (HB) is a rare, hereditary disease caused by a defect in the gene encoding factor IX (FIX) and leads to varying degrees of coagulation deficiency. The prevailing treatment for people with HB (PWHB) is FIX replacement product. The advent of recombinant coagulation products ushered in a new era of safety, efficacy, and improved availability compared with plasma-derived products. For people with severe HB, lifelong prophylaxis with a FIX replacement product is standard of care. Development of extended half-life FIX replacement products has allowed for advancements in the care of these PWHB. Nonetheless, lifelong need for periodic dosing and complex surveillance protocols pose substantive challenges in terms of access, adherence, and healthcare resource utilization. Further, some PWHB on prophylactic regimens continue to experience breakthrough bleeds and joint damage, and subpopulations of PWHB, including women, those with mild-to-moderate HB, and those with inhibitors to FIX, experience additional unique difficulties. This review summarizes the current challenges faced by PWHB, including the unique subpopulations; identifying the need for improved awareness, personalized care strategies, and new therapeutic options for severe HB, which may provide future solutions for some of the remaining unmet needs of PWHB.

Abstract
Neuraxial anesthesia is the preferred technique for total joint arthroplasties. However, the absolute safety of neuraxial anesthesia in hemophilia patients has not been established. We describe a case of an adult male with severe hemophilia A, who presented for primary hip replacement due to severe hemophilic arthropathy and was managed with ultrasound-facilitated neuraxial anesthesia. Due to bleeding risks, additional considerations were necessary to minimize development of postoperative spinal hematoma. There were no perioperative adverse events. Careful preoperative multidisciplinary planning, perioperative management of neuraxial anesthesia (including the use of spinal ultrasound), and hemostasis were instrumental to successfully accomplish this. Following these principles, we demonstrate that neuraxial techniques may be a safe option for managing patients with severe hemophilia A.

Women and girls with haemophilia: A retrospective cohort study in China. Haemophilia 2023; 29:578-590. [PMID: 36595620 DOI: 10.1111/hae.14740] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 11/14/2022] [Accepted: 12/18/2022] [Indexed: 01/05/2023]
Abstract
INTRODUCTION Women and girls with haemophilia (WGH) may have spontaneous/traumatic bleeding similar to that in males with haemophilia, and in addition excessive bleeding during menstruation and delivery. AIM To characterize WGH in China and provide guidance for better management. METHODS We retrospectively analysed the characteristics of WGH registered in the Haemophilia Treatment Center Collaborative Network of China (HTCCNC) Registry, including demographics, diagnosis and treatment, bleeding characteristics, obstetrical and gynaecological experiences, and surgical history. RESULTS A total of 61 females had confirmed haemophilia. Diagnosis and treatment were typically delayed, longer in mild haemophilia than in severe and moderate. The most frequently reported bleeding manifestations were haemarthrosis in severe and moderate patients, and cutaneous bleeding in mild patients. Among 45 postmenarcheal WGH, 21 (46.7%) had history of heavy menstrual bleeding, but only three received treatments. Prenatal diagnosis and management of perinatal haemorrhage were inadequate. Of 34 deliveries in 30 women, nine deliveries were complicated by postpartum haemorrhage, and 22 offspring carried mutations causing haemophilia. Forty-four surgical procedures were performed in 29 patients. Those procedures receiving preoperative coagulation factors coverage were significantly less likely to have excessive bleeding than those who did not (P = .003). CONCLUSION This is the first and largest study describing WGH in China. There are currently deficiencies in the identification, diagnosis, and management of these patients. Improving health insurance policies, establishing haemophilia centres, and multidisciplinary teams for bleeding and perinatal or perioperative management will help reduce morbidity and mortality.

Abstract
BACKGROUND Pregnancy, peripartum management, and outcomes of mild hemophiliacs and hemophilia carriers in the United States are not well established. AIM To describe the management and outcomes of mild hemophiliacs and hemophilia carriers during assisted conception, pregnancy, peripartum and post-partum period at our hemophilia treatment center (HTC). METHODS Retrospective review of electronic medical records of pregnant women with mild hemophilia A or B (Factor VIII [FVIII] or Factor IX [FIX] level <0.4 IU/mL) and hemophilia A and B carriers followed at our HTC from January 2008 to October 2020. Demographics, the reason for diagnosis, FVIII and FIX levels at baseline and third trimester, bleeding phenotype and genotype were obtained. Method of conception, factor replacement, iron supplementation, mode of delivery, type of anesthesia, peripartum complications, and offspring outcomes was recorded. RESULTS There was a total of 18 pregnancies in 12 women (2 with mild hemophilia A, 2 mild hemophilia B, 6 hemophilia A carriers, and 2 hemophilia B carriers). Eleven pregnancies (61%) were conceived naturally and 7 (39%) via in-vitro fertilization (IVF). Eight (44.4%) and 10 (55.6%) pregnancies were vaginal and C-section deliveries, respectively. Neuraxial anesthesia was administered in 17 (94.4%) deliveries without complications. Four pregnancies (22.2%) had bleeding complications, 2 of which were post-partum hemorrhages not requiring transfusion. CONCLUSION In our case series of pregnant hemophilia carriers and mild hemophiliacs, successful outcomes were achieved with a carefully detailed multidisciplinary-driven approach.
