Abstract Figures in the World Federation of Hemophilia (WFH) global annual survey indicate, by their absence, that there is under-recognition of bleeding disorders in women. The WFH and its national member organisations (NMOs) are working to raise awareness and improve the diagnosis of care of women with bleeding disorders globally, regionally and locally. WFH initiatives include a global programme focused on improving the diagnosis, care and treatment of women with von Willebrand disease (VWD), and programmes involving education and training in conjunction with NMOs in countries including Honduras and Malaysia. NMOs in Slovakia, Latvia and Sweden describe their local activities. The Slovak Hemophilia Society is in the process of establishing a Women’s Committee and considers peer support and network building as essential tools in addressing the issues faced by women with bleeding disorders. In Latvia, access to resources is difficult and von Willebrand factor is not available. There is concern in the Latvia Hemophilia Society that the fundamental human right of access to healthcare is not being met. It supports WFH initiatives through education and advocacy, and believes that the voices of women with bleeding disorders will be better heard through working together. The Swedish Hemophilia Society’s Women’s Project has worked since 2006 to promote better care for women with bleeding disorders and to raise public awareness. Despite resistance, their campaign to increase the identification of girls and women with VWD, improve diagnosis and care, and raise awareness has been well received by healthcare professionals and has had extensive media coverage.
世界血友病联合会(WFH)全球年度调查的数据表明,由于缺乏这些数据,人们对女性出血性疾病的认识不足。世界妇女联合会及其国家成员组织(NMOs)正在努力在全球、区域和地方提高对出血性疾病妇女的认识并改进诊断。世界妇女健康倡议包括一项全球方案,重点是改善患有血管性血友病的妇女的诊断、护理和治疗,以及在洪都拉斯和马来西亚等国与非政府组织合作开展的教育和培训方案。斯洛伐克、拉脱维亚和瑞典的非政府组织描述了它们在当地的活动。斯洛伐克血友病协会正在建立一个妇女委员会,并认为同伴支持和网络建设是解决出血性疾病妇女所面临问题的基本工具。在拉脱维亚,很难获得资源,而且没有冯维勒布兰特因素。拉脱维亚血友病协会关切的是,获得医疗保健的基本人权没有得到满足。它通过教育和宣传支持世界出血性疾病联合会的倡议,并相信通过共同努力,出血性疾病妇女的声音将得到更好的倾听。瑞典血友病协会的妇女项目自2006年以来一直致力于促进对出血性疾病妇女的更好护理,并提高公众认识。尽管存在阻力,但她们开展的运动提高了对女童和妇女感染埃博拉病毒的认识,改善了诊断和护理,提高了认识,受到卫生保健专业人员的欢迎,并得到了媒体的广泛报道。

Abstract Pain continues to be a significant issue for people with haemophilia (PWH), whether it is acute pain from a joint bleed, a needle stick when receiving clotting factor treatment, or chronic pain from chronic synovitis and arthritic changes. In the US, there has been controversy and uncertainty regarding the use of oral medications and opioids for the management of chronic pain, including haemophilia pain. Both PWH and their clinicians have started to explore nonpharmacologic options for managing pain, with many PWH trying to limit their use of oral pain medication and using alternative methods. There is little research around the use of complementary and alternative medicine (CAM) for pain management in the haemophilia community. This paper aims to provide a comprehensive literature review of current English language research on the use of therapies that fall into four distinctive domains of CAM in PWH. English language articles were obtained via searches in Medline, Embase and CINAHL using the target search words “haemophilia” or “bleeding disorders” in combination with other search terms relating to CAM. All references were considered regardless of year. Twenty-three CAM articles that included PWH or other bleeding disorders were identified; ten were evidence based while the remainder provided case reports and descriptions of CAM use in PWH. This indicates that there is limited current research in the area of CAM use for pain management in PWH. Evidence of the benefit of CAM is seen in studies of its use to treat pain in other conditions and health-related circumstances. Additional evidenced-based CAM research is needed so that alternative pain management therapies can be utilised in a safe and beneficial manner in PWH.
疼痛仍然是血友病(PWH)患者的一个重要问题,无论是关节出血、接受凝血因子治疗时针刺引起的急性疼痛,还是慢性滑膜炎和关节炎改变引起的慢性疼痛。在美国,使用口服药物和阿片类药物治疗慢性疼痛(包括血友病疼痛)一直存在争议和不确定性。PWH和他们的临床医生都开始探索非药物治疗疼痛的选择,许多PWH试图限制口服止痛药的使用,并使用其他方法。关于在血友病社区使用补充和替代医学(CAM)进行疼痛管理的研究很少。本文的目的是提供一个全面的文献综述,目前的英语语言研究中,治疗的使用属于四个不同领域的CAM在PWH。通过在Medline, Embase和CINAHL中使用目标搜索词“血友病”或“出血性疾病”以及与CAM相关的其他搜索词进行搜索获得英语文章。不论年份,所有参考文献均被考虑。23篇CAM文章包括PWH或其他出血性疾病;其中10份是基于证据的,其余的提供了病例报告和在PWH中使用CAM的描述。这表明,有有限的目前研究领域的CAM用于疼痛管理在PWH。辅助治疗在治疗其他疾病和健康相关情况下的疼痛方面的研究显示了辅助治疗的益处。需要更多基于证据的CAM研究,以便在PWH中以安全和有益的方式使用替代疼痛管理疗法。

Bleeding disorders in girls and women: setting the scene 女童和妇女出血性疾病:背景

Abstract The prevalence and impact of bleeding disorders in women is not sufficiently acknowledged, with the organisation of care traditionally biased towards boys and men with haemophilia. In 2017, the European Haemophilia Consortium surveyed women with bleeding disorders, national member organisations (NMOs) and treatment centres to assess the impact of bleeding disorders in women in four domains: physical activity, active life, romantic and social life, and reproductive life. Most women had von Willebrand disease (VWD) or described themselves as a carrier. All reported a negative impact on physical activity, active life and romantic and social life. Up to 70% of women in all groups reported that their bleeding disorder had a significant impact on their ability or willingness to have children, or prevented it. Heavy menstrual bleeding was reported as the having the most significant impact on daily life. Women face barriers to diagnosis and care, including difficulty obtaining a referral and lack of knowledge among general practitioners and gynaecologists. While bleeding disorders share many symptoms, including bleeding after minor injury and trauma, the link between heavy menstrual bleeding and a bleeding disorder often goes unrecognised and its severity is underestimated. Screening is not offered to all eligible women despite the availability of long-established management guidelines; clinical tools to estimate severity may be unreliable. Failure to recognise a bleeding disorder in a woman is a multifactorial problem that is partly due to cultural reluctance to discuss menstruation. Public awareness campaigns are seeking to correct this, and many NMOs involve women in their initiatives and provide women-centred activities. However, a transformation in diagnosis is needed to shift the focus of treatment centres beyond boys and men with haemophilia, and to acknowledge the prevalence and severity of bleeding disorders in women.
女性出血性疾病的患病率和影响尚未得到充分承认,传统上的护理组织偏向于患有血友病的男孩和男性。2017年,欧洲血友病联盟调查了出血性疾病妇女、国家成员组织(NMOs)和治疗中心,以评估出血性疾病在四个领域对妇女的影响:身体活动、积极生活、浪漫和社交生活以及生殖生活。大多数妇女患有血管性血友病(VWD)或自称为携带者。所有人都报告了对身体活动、积极生活、浪漫生活和社交生活的负面影响。所有组中高达70%的妇女报告说,她们的出血性疾病对她们生育的能力或意愿有重大影响,或者阻止了生育。据报道,大量月经出血对日常生活的影响最大。妇女在诊断和护理方面面临障碍,包括难以获得转诊以及全科医生和妇科医生缺乏知识。虽然出血性疾病有许多共同症状,包括轻微伤害和创伤后出血,但大量月经出血与出血性疾病之间的联系往往未被认识到,其严重程度也被低估。尽管有长期确立的管理指南,但并没有向所有符合条件的妇女提供筛查;估计严重程度的临床工具可能不可靠。不能识别出女性的出血性疾病是一个多因素的问题,部分原因是文化上不愿讨论月经。公众认识运动正在设法纠正这种情况,许多非政府组织让妇女参与其倡议并提供以妇女为中心的活动。然而,需要改变诊断,将治疗中心的重点转移到患有血友病的男孩和男性之外,并承认出血性疾病在妇女中的患病率和严重性。

The Ugandan Treatment Gap – Peter Nangalu 乌干达的治疗差距——Peter Nangalu
Pub Date : 2019-01-01 DOI: 10.17225/jhp00137
Luke Pembroke
Many people in the haemophilia community are aware of the disparity in access to healthcare and resources between developed and economically developing countries. In Uganda, for example, it is estimated that only four out of every 100 people with haemophilia are diagnosed. Access to effective treatments is severely limited, and care for people with haemophilia is available only from Mulago Hospital in the capital, Kampala. Prophylactic factor replacement is not an option, and humanitarian aid donations have allowed for on-demand factor treatment only in recent years. According to the World Federation of Hemophilia, per capita use of factor VIII in Uganda is around 350 times lower than in the UK . Speaking with Peter Nangalu reveals what that treatment gap means for people living with haemophilia. Peter is 23 years old. Despite having severe haemophilia, he is studying computer science at Kampala University. It is an impressive achievement to have got so far: many people born with haemophilia in Uganda do not survive into adulthood. The resilience and strength Peter has shown throughout his life is truly remarkable. Problems started for Peter at age two, when he suspects an attack of malaria marked the first manifestations of haemophilia.
血友病社区的许多人都意识到发达国家和经济发展中国家在获得医疗保健和资源方面的差距。例如,在乌干达,据估计每100名血友病患者中只有4人得到诊断。获得有效治疗的机会严重有限,只有首都坎帕拉的穆拉戈医院才能提供对血友病患者的护理。预防性因子替代不是一种选择,人道主义援助捐款仅在最近几年才允许按需因子治疗。根据世界血友病联合会的数据,乌干达人均第八因子使用量比英国低约350倍。与Peter Nangalu的谈话揭示了治疗差距对血友病患者意味着什么。彼得23岁。尽管患有严重的血友病,他仍在坎帕拉大学学习计算机科学。到目前为止,这是一个令人印象深刻的成就:在乌干达,许多患有血友病的人无法活到成年。彼得在他的一生中所表现出的韧性和力量是非常了不起的。彼得在两岁时就开始出现问题,当时他怀疑疟疾的发作标志着血友病的最初表现。

K in F Kam is an inventor and writer who has severe haemophilia A. Born in Hong Kong in 1967, at age ten he came to the UK with his mother and two brothers to join his father, who had established a successful fish and chip shop in Oldham, Greater Manchester. He went on to academic success at university, obtained a doctorate and followed a career in research before going on to develop and market his inventions. All this he recounts in his autobiography Blood, Dragons & Lions. So far, so impressive. But Kin lived with the challenges of having haemophilia and being an immigrant from a minority ethnic group – a double dose of difference that weighed heavily on a child growing up in the North West of England during the ‘70s and ‘80s. The experience of coping with haemophilia and the associated stigma was so traumatic that he couldn’t bring himself to use the word throughout most of his book, referring to his condition only as ‘H’.
他是一位发明家和作家,患有严重的血友病a。1967年出生于香港,10岁时随母亲和两个兄弟来到英国,与父亲一起在大曼彻斯特的奥尔德姆开了一家成功的炸鱼薯条店。他在大学里取得了学业上的成功,获得了博士学位,在继续开发和销售他的发明之前,他从事研究工作。他在自传《血、龙与狮》中详述了这一切。到目前为止,令人印象深刻。但是金的生活面临着血友病和少数民族移民的双重挑战——这对一个在70年代和80年代在英格兰西北部长大的孩子来说是沉重的负担。与血友病和相关的耻辱打交道的经历给他带来了巨大的创伤,以至于他在书的大部分时间里都无法让自己使用这个词,只把自己的病情称为“H”。

Opioid dependence among people with haemophilia in a low-resource tropical setting: prevalence and risk factors in northern Nigeria 资源匮乏的热带环境中血友病患者的阿片类药物依赖:尼日利亚北部的流行率和危险因素
Pub Date : 2019-01-01 DOI: 10.17225/jhp00132

Abstract Background In tropical countries such as Nigeria, where factor VIII (FVIII) is scarce, severe pain due to musculoskeletal bleeding complications, leading to frequent opioid prescription, is not uncommon in poorly managed people with haemophilia (PWH). The relationship between opioid use and dependence is intensively studied in other painful diseases, such as cancer and rheumatoid arthritis, but surprisingly little is known about opioid dependence in haemophilia. We hypothesise that the risk of opioid dependence among PWH in tropical countries like Nigeria is multi-factorial, encompassing demographic (age), clinical (haemophilia severity and chronic arthropathy) and biological (ABO blood groups and haemoglobin (Hb) phenotypes) factors that may directly or indirectly increase incidence of bleeding and/or pain. Aims To determine the prevalence of opioid dependence and relative risks (RR) associated with age, haemophilia severity, chronic arthropathy, ABO blood groups and Hb phenotypes, and to elucidate the pathophysiological roles of each risk factor in the development of opioid dependence among haemophilia-A patients in five hospitals in northern Nigeria. Methodology A retrospective review of the medical records of 88 PWH seen between 1996 and 2012 was used to collate data on age, sex, haemophilia severity, painful chronic haemophilic arthropathy, ABO blood group, haemoglobin phenotypes, presence or absence of opioid dependence, and the types of opioids on which the patients were dependent. The prevalence of opioid dependence among the cohort was expressed as a percentage. The frequency of each putative risk factor for opioid dependence in patients with and without opioid dependence were compared using Fisher’s exact test; RR associated with each risk factor was determined by regression analysis. P<0.05 was taken as significant. Results Of the 88 PWH studied,15 (17%) were shown to be opioid-dependent. Compared with PWH who were not opioid-dependent, this group had higher frequencies of severe haemophilia (86.7% vs. 49.3%: RR= 5.2, p=0.02), survival to adulthood (73.3% vs. 12.3%: RR= 9.5, p=0.0001), chronic arthropathy in one or more joints (86.7% vs. 21.9%: RR= 13.2, p=0.0004), blood group-O (80% vs. 49.3%: RR= 3.3, p=0.04), and HbAA phenotype (86.7% vs. 54.8%: RR= 4.3, p=0.04). Conclusion Prevalence of opioid dependence among PWH treated at five hospitals in northern Nigeria was 17% during the study period. Significant risk factors were directly or indirectly associated with increased rates of bleeding and/or pain, which can only be prevented or treated through optimal application of FVIII. There is a need for the Nigerian government to establish standard haemophilia care centres with adequate FVIII for optimal prophylaxis and treatment in order to minimise painful complications, thereby helping to prevent undue opioid use and dependence.
背景:在尼日利亚等缺乏因子VIII (FVIII)的热带国家,由于肌肉骨骼出血并发症引起的严重疼痛,导致频繁的阿片类药物处方,在管理不善的血友病(PWH)患者中并不罕见。阿片类药物使用与依赖之间的关系在其他疼痛疾病中得到了深入研究,如癌症和类风湿关节炎,但令人惊讶的是,对血友病中的阿片类药物依赖知之甚少。我们假设,在尼日利亚等热带国家的PWH中,阿片类药物依赖的风险是多因素的,包括人口统计学(年龄)、临床(血友病严重程度和慢性关节病)和生物学(ABO血型和血红蛋白(Hb)表型)因素,这些因素可能直接或间接增加出血和/或疼痛的发生率。目的了解尼日利亚北部5家医院血友病a- a患者阿片类药物依赖的患病率及与年龄、血友病严重程度、慢性关节病、ABO血型和Hb表型相关的相对危险度(RR),并阐明各危险因素在阿片类药物依赖发展中的病理生理作用。方法回顾性分析1996年至2012年间88例PWH患者的医疗记录,整理年龄、性别、血友病严重程度、疼痛性慢性血友病关节病、ABO血型、血红蛋白表型、是否存在阿片类药物依赖以及患者依赖的阿片类药物类型等数据。阿片类药物依赖在队列中的流行率以百分比表示。使用Fisher精确检验比较阿片类药物依赖患者和非阿片类药物依赖患者中每个假定危险因素的频率;通过回归分析确定各危险因素的相关RR。P<0.05为差异有统计学意义。结果88例PWH患者中,15例(17%)显示阿片类药物依赖。与非阿片类药物依赖的PWH相比,该组有更高的频率发生严重血友病(86.7% vs. 49.3%: RR= 5.2, p=0.02)、成年生存率(73.3% vs. 12.3%: RR= 9.5, p=0.0001)、一个或多个关节的慢性关节病变(86.7% vs. 21.9%: RR= 13.2, p=0.0004)、o型血(80% vs. 49.3%: RR= 3.3, p=0.04)和HbAA表型(86.7% vs. 54.8%: RR= 4.3, p=0.04)。结论在研究期间,尼日利亚北部五家医院接受治疗的PWH中阿片类药物依赖的患病率为17%。重要的危险因素与出血和/或疼痛发生率的增加直接或间接相关,这只能通过FVIII的最佳应用来预防或治疗。尼日利亚政府需要建立标准的血友病护理中心,提供充足的FVIII,以实现最佳预防和治疗,以尽量减少痛苦的并发症,从而帮助防止阿片类药物的过度使用和依赖。

The frequency of each putative risk factor for opioid dependence in patients with and without opioid dependence were compared using Fisher’s exact test; RR associated with each risk factor was determined by regression analysis. P<0.05 was taken as significant. Results Of the 88 PWH studied,15 (17%) were shown to be opioid-dependent. Compared with PWH who were not opioid-dependent, this group had higher frequencies of severe haemophilia (86.7% vs. 49.3%: RR= 5.2, p=0.02), survival to adulthood (73.3% vs. 12.3%: RR= 9.5, p=0.0001), chronic arthropathy in one or more joints (86.7% vs. 21.9%: RR= 13.2, p=0.0004), blood group-O (80% vs. 49.3%: RR= 3.3, p=0.04), and HbAA phenotype (86.7% vs. 54.8%: RR= 4.3, p=0.04). Conclusion Prevalence of opioid dependence among PWH treated at five hospitals in northern Nigeria was 17% during the study period. Significant risk factors were directly or indirectly associated with increased rates of bleeding and/or pain, which can only be prevented or treated through optimal application of FVIII. There is a need for the Nigerian government to establish standard haemophilia care centres with adequate FVIII for optimal prophylaxis and treatment in order to minimise painful complications, thereby helping to prevent undue opioid use and dependence.","PeriodicalId":372940,"journal":{"name":"The Journal of Haemophilia Practice","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127136387","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Men and women with bleeding disorders have similar symptoms but their experiences are different. It has been shown that women with a bleeding disorder rate their quality of life on a par with that of men with haemophilia who have HIV. Many factors determine quality of life, ranging from delay in diagnosis, to access to treatment and support from family and friends. Women should ask themselves what is important to them and recognise the barriers that determine whether they can achieve their aims in life. Quality of life instruments do not measure the impact of these disorders in a way that is specific to women. Psychosocial health – i.e. the mental, emotional, social, and spiritual aspects of what it means to be healthy – can have a major impact on quality of life. Women with bleeding disorders face a number of challenges to their psychosocial health. They struggle to be believed, they live with guilt, and they may have to fight for the best care for their children. They face obstacles to building relationships and their experiences can leave them isolated. Perhaps because of this, women with bleeding disorders are strong – but they also need to be encouraged to make time for themselves and look after their mental health.
出血性疾病的男性和女性具有相似的症状,但他们的经历不同。研究表明,患有出血性疾病的女性对生活质量的评价与患有血友病并感染艾滋病毒的男性相当。许多因素决定生活质量,从诊断延误到获得治疗和来自家人和朋友的支持。女性应该问问自己,什么对她们来说是重要的,并认识到决定她们能否实现人生目标的障碍。生活质量工具并没有以一种专门针对妇女的方式衡量这些疾病的影响。社会心理健康——即健康的心理、情感、社会和精神层面——可以对生活质量产生重大影响。患有出血性疾病的妇女在心理社会健康方面面临许多挑战。他们挣扎着让别人相信他们,他们生活在内疚中,他们可能不得不为孩子争取最好的照顾。他们在建立人际关系方面面临障碍,他们的经历会让他们孤立无援。也许正因为如此,患有出血性疾病的女性很坚强——但也需要鼓励她们为自己腾出时间,照顾好自己的精神健康。

Abstract Prolonged menstrual bleeding interferes with daily life and causes marked blood loss, resulting in anaemia and fatigue. Treatment centres should address the issue of heavy menstrual bleeding (HMB) with pre-pubertal girls in advance of their first period, in order to best prepare them. It is common for a bleeding disorder to be overlooked in primary care and in gynaecology clinics, and women sometimes struggle to get a correct diagnosis. There are cultural taboos that inhibit open discussion of menstruation, and women tend to minimise the severity of their symptoms. Health professionals should work to destigmatise the issue and seek an accurate account of bleeding severity, with diagnosis and treatment provided in a joint clinic combining gynaecology and haematology expertise. Treatment should be individualised, taking into account personal, social and medical factors, with the aim of improving quality of life. Great care is needed with regard to choice of language when talking about treatment, and treatment centres should consider offering open access to women who need support in dealing with adverse effects. National member organisations have an important role to play in educating people with bleeding disorders, health professionals and the wider public about the burden of HMB associated with bleeding disorders.
经期出血延长干扰日常生活,引起明显的失血,导致贫血和疲劳。治疗中心应该在青春期前的女孩第一次月经之前处理月经大量出血的问题,以便为她们做好最好的准备。出血性疾病在初级保健和妇科诊所被忽视是很常见的,妇女有时很难得到正确的诊断。有些文化禁忌禁止公开讨论月经问题,女性也倾向于将症状的严重程度降到最低。卫生专业人员应努力消除这一问题的污名化,并寻求出血严重程度的准确描述,在结合妇科和血液学专业知识的联合诊所提供诊断和治疗。治疗应个体化,考虑到个人、社会和医疗因素,以提高生活质量为目标。在谈论治疗时,在选择语言方面需要非常小心,治疗中心应考虑向在处理不良影响方面需要支持的妇女开放。国家成员组织在教育出血性疾病患者、卫生专业人员和广大公众关于与出血性疾病相关的HMB负担方面发挥着重要作用。

Abstract This article describes a case of wrongly managed haemophilic arthropathy in a 15-year-old boy in Uganda. Delayed diagnosis of haemophilia and misdiagnosis of haemophilic arthropathy resulted in unnecessary corrective surgery and potentially severe complications. After haemophilia was diagnosed, he was managed by haematologists using factor VIII and regular physiotherapy. The physiotherapy treatment approach focused in particular on functional activities, which was beneficial in achieving quicker results and made the patient’s rehabilitation more meaningful. This case indicates that there is a need for greater awareness of the presentation of haemophilia in developing countries.

Abstract Background Scarcity of FVIII concentrate compels caregivers in poor countries to use multiple transfusions of fresh whole blood (FWB), fresh frozen plasma and cryoprecipitate for managing haemophilia A. FWB is the most frequently transfused blood product due to ease of production and its ability to simultaneously stop active bleeding and treat anaemia. Iron deficiency anaemia is common among haemophiliacs in poor tropical countries such as Nigeria, due to the combined effects of bleeding, malnutrition, and haemorrhagic parasitic diseases. Multiple FWB transfusion is usually initiated at local sub-tertiary hospitals before eventual referral to tertiary hospitals. The Nigerian blood transfusion service is underdeveloped, donor screening is rudimentary and transfusion safety is poor. The prevalence of transfusion transmissible viral infections (TTVIs), including HIV, and hepatitis B and C viruses (HBV and HCV), is therefore predicted to be high among Nigerian haemophiliacs. Aims To determine prevalence and pattern of TTVIs (HIV, HBV, HCV infections) among paediatric haemophiliacs who have received multiple FWB transfusions in Nigeria. Materials and methods Retrospective analyses of demographic and clinical data, disease severity, number of previous transfusions of FWB, and prevalence and pattern of TTVIs (HIV, HBV and HCV infections) of newly referred haemophiliacs as seen in five tertiary hospitals in northern Nigeria. Prevalence rates of TTVIs were expressed as percentages. Comparisons of parameters (age, disease severity and number of previous transfusions) between patients with and without TTVIs were performed using Students t-test for mean values and Fisher’s exact test for percentages, with p-values of less than 0.05 taken as significant. Results Of 97haemophiliacs studied, 24 (24.7%) were infected with TTVIs. The pattern and frequencies of TTVIs among the infected patients revealed HBV infection in 10 (41.7%), HIV-1 infection in five (20.8%), HCV infection in four (16.7%), HBV and HIV co-infection in three (12.5%), and HBV and HCV co-infection in two (8.3%). In comparison with haemophiliacs without TTVIs, haemophiliacs with TTVIs had a significantly lower mean age (4.9 vs. 7.8; p=0.007); a higher proportion of severe disease (62.5% vs. 26%; p=0.009), and a higher mean number of transfusions per patient (27.5 vs. 15.3; p=0.006). Conclusions The prevalence of TTVIs among haemophiliacs in Nigeria is high, and the risk is correlated with disease severity and number of previous transfusions. There is need for the national transfusion service to be upgraded and for standard haemophilia care centres with an adequate supply of FVIII concentrates for optimal care to be set up. Haemophilia healthcare providers in Nigeria can minimise multiple transfusions by incorporating regular screening and treatment of haemorrhagic parasitic diseases, iron supplementation, and the use of pharmacological agents in the standard of care for haemophilia.
背景:FVIII浓缩物的缺乏迫使贫穷国家的护理人员使用新鲜全血(FWB)、新鲜冷冻血浆和冷冻沉淀多次输注来治疗a型血友病。FWB是最常用的输注血液制品,因为它易于生产,并且能够同时阻止活动性出血和治疗贫血。由于出血、营养不良和出血性寄生虫病的综合影响,缺铁性贫血在尼日利亚等贫穷热带国家的血友病患者中很常见。在最终转诊到三级医院之前,通常先在当地的二级三级医院进行多次FWB输血。尼日利亚输血服务不发达,献血者筛查不完善,输血安全性差。因此,预计尼日利亚血友病患者中输血传播病毒感染(TTVIs)的流行率很高,包括艾滋病毒以及乙型和丙型肝炎病毒(HBV和HCV)。目的确定尼日利亚接受过多次FWB输血的儿科血友病患者中TTVIs (HIV、HBV、HCV感染)的流行情况和模式。材料和方法回顾性分析尼日利亚北部五家三级医院新转诊血友病患者的人口统计学和临床数据、疾病严重程度、以前输注FWB的次数以及TTVIs(艾滋病毒、乙型肝炎病毒和丙型肝炎病毒感染)的患病率和模式。tti患病率以百分比表示。TTVIs患者和非TTVIs患者的参数(年龄、疾病严重程度和既往输血次数)比较采用student t检验表示平均值,Fisher精确检验表示百分比,p值小于0.05为显著性。结果97例血友病患者中,24例(24.7%)感染TTVIs。感染患者TTVIs的类型和频率显示HBV感染10例(41.7%),HIV-1感染5例(20.8%),HCV感染4例(16.7%),HBV和HIV合并感染3例(12.5%),HBV和HCV合并感染2例(8.3%)。与没有TTVIs的血友病患者相比,有TTVIs的血友病患者的平均年龄显著降低(4.9 vs. 7.8;p = 0.007);严重疾病的比例更高(62.5% vs. 26%;P =0.009),每位患者的平均输血次数更高(27.5次vs 15.3次;p = 0.006)。结论尼日利亚血友病患者TTVIs患病率较高,感染风险与疾病严重程度和既往输血次数有关。有必要升级国家输血服务,并建立标准的血友病护理中心,提供足够的FVIII浓缩物,以提供最佳护理。尼日利亚的血友病卫生保健提供者可以通过将定期筛查和治疗出血性寄生虫病、补充铁以及在血友病护理标准中使用药理学药物来最大限度地减少多次输血。
