再生障碍性贫血到底有多严重？
“车祸、失忆、白血病”被网友们戏称为“日韩剧三宝”，以至于有些人将再生障碍性贫血等血液疾病误认为是白血病，而意志消沉贻误治疗。那么――再生障碍性贫血到底有多严重？
“医生，你多取点骨髓，别让我儿子不够用。”在进入手术室前，江刘平多次向医生表达自己的意愿。由于患有极重型再生障碍性贫血的儿子江雨航迟迟没找到合适的捐献者，江刘平决定捐献自己的造血干细胞和骨髓。
资料显示，再生障碍性贫血在欧美为罕见疾病，发病率为2个／百万人口，亚洲国家再障发病率明显高于西方国家。我国发病率约为8个／百万人口，可见于各种年龄和性别人群。由于我国庞大的人口基数，再障的实际发病人数较多。
重型再障致死率高
“其实血液病中有很多类型是良性疾病，包括再生障碍性贫血。”北京协和医院血液内科主任医师韩冰教授解释说，再障与白血病是两回事，用通俗的语言来说，再障是骨髓不造血了，而白血病则是骨髓造出了坏血，发病机理是完全不一样的。因此，两者的治疗效果和长期生存率也相差很大。
根据韩冰的观察，患者和亲友对再障的认识容易走两个极端――要么认为再障就是白血病，没治了，要么认为再障就是一般“贫血”，不治、慢慢治也无所谓。
“再障确实不是肿瘤，但是也不等于可以置之不理。”韩冰解释说，再障，是一种骨髓造血功能衰竭症，常常表现为面色苍白、头晕气短、鼻孔和牙龈出血、感染发热等。根据疾病严重程度，再障分为重再障、极重型再障和非重型再障。“重型再障一旦发病可能命悬一线。”韩冰透露，有些再障起病就是重型，重型再障病人起病急，病情危重，需要得到有效的大剂量的联合免疫抑制治疗甚至是骨髓移植治疗才能治愈。
韩冰表示，重型再障就如同一位出手迅速的冷面杀手，虽然并非是不可治愈的恶性血液疾病，但是起病急的重型，假如得不到非常及时而且有效的治疗，一旦治疗拖延就会导致严重的感染、出血等并发症，绝大多数在3至6个月内会死亡。一般而言起病后的40天内治疗是重型再障治疗的最佳时机。
治疗技术日趋成熟
“目前患者和家属对再障认识的误区，往往就在于对不同类型再障的认识错位。”韩冰说，目前再障的诊断和治疗技术日趋成熟，困难不大。主要困难首先是患者及其家属对再障认识的不足，未能及时到有经验的医疗中心采取正规的治疗，贻误治疗时机；再就是高额的医药费用限制了正规或及时的治疗，重型再障治疗费用可以从几万元到几十万元甚至更高，而且大多是一些昂贵药品，属于自费范畴。
韩冰介绍说，再障治疗方案的制定需要针对再障的不同类型和每个患者的个体情况而异。重型再障和非重型再障的治疗方案更是完全不同：对于慢性的非重型再障，一般采取单用环孢霉素、雄激素、中医中药或以上几种联合治疗，往往起效较慢，常两三个月才开始起效，治疗上必须要有耐心。值得注意的是，即使是慢性的非重型再障，也有部分最终会转化为重型再障；但是对于起病急骤的重型再障患者，尤其是小部分极重型再障患者来说，其病情凶险，危害甚至超过急性白血病，必须抓紧时间进行骨髓移植或是大剂量联合免疫抑制治疗，否则很快死亡。“重型再障规范性治疗后疗效显著，部分患者生活质量和工作能力可以恢复到健康人的水平。”
“免疫抑制治疗近年来得到充分肯定，并取得显著疗效的重型再障治疗方案。”韩冰透露，国际上，大量临床数据肯定了以兔抗胸腺细胞免疫球蛋白（r-ATG），即复宁为代表的免疫抑制治疗的价值。迄今为止，抗胸腺细胞免疫球蛋白（r-ATG）即复宁是唯一在中国获准用于治疗重型再生障碍性贫血的进口ATG产品，目前已普遍用于治疗重型再障。
规范治疗重型再障
“重型再障通过规范化的治疗，即造血干细胞移植和强化免疫治疗，能使患者有很大机会获得治愈。”韩冰指出，“尽管造血干细胞移植的治疗价值备受瞩目，但众多患者不得不面对缺乏相合干细胞供体的残酷现实，很多患者因为没有等到合适的供体而遗憾离世。此外，年龄也是骨髓移植手术的一道障碍。”
韩冰透露，目前，专家的共识是，40岁以下的重型再障患者如能进行同胞配型相合的骨髓移植能取得非常好的治疗效果。通常来说，患者年龄大于40岁HLA相合同胞供者骨髓移植效果就会显著下降。“因此，对于没有合适配型供者的重型再障患者，免疫抑制治疗有时可能是成为患者唯一的生存希望。”
韩冰表示，重型再障疾病在采取造血干细胞移植治疗或强化免疫治疗的规范化治疗期间，患者负担药物治疗所需要的一次性费用较高，但后续治疗费用相对较少。而一部分经济困难的患者由于难以支付前期的治疗费用，造成延误病情影响治疗效果，或者由于没有及时得到规范治疗而出现严重感染或死亡。“其实，规范的治疗可以大大提高患者生存率，例如，以即复宁为基础的免疫抑制治疗有效率达70―80%，5年总生存率80―90%，疗效与同胞相合骨髓移植相似。”
“再生障碍性贫血的治疗是一个长期的过程，无论临床医生还是患者家属都应注意赋予患者更多的支持。”韩冰再三强调。

【medical-news】再生障碍性贫血：不再是不治之症
Aplastic Anemia: A Rare Disease With a Better PrognosisAdvances are prolonging the lives of people with this once-fatal illness HealthDaySunday, February 4, 2007 SUNDAY, Feb. 4 (HealthDay News) -- Aplastic anemia, a disease of the bone marrow, is a rare disorder in the United States. Only three of every 1 million Americans will be diagnosed with the condition this year, the National Marrow Donor Program reports.Despite that rarity, this once-fatal disease has become far more treatable as physicians have honed in on practices that can prolong life and ease suffering.And the effects of that research extend far beyond sufferers of aplastic anemia or other related bone marrow diseases. Insights gained from these diseases are also helping scientists learn about more prevalent health problems, such as heart disease or leukemia, researchers say.Aplastic anemia occurs when bone marrow stops producing enough blood cells, said Katherine Baer, a patient information specialist for the Aplastic Anemia and MDS International Foundation Inc. Only about 1,000 new cases appear each year in the United States.A related blood disorder, myelodysplastic syndromes, or MDS, occurs when the bone marrow begins producing poorly functioning or immature blood cells. About 20,000 to 30,000 new cases occur each year.Doctors still aren't certain exactly what causes the diseases' onset, Baer said."They do th there are some toxins that may cause it, like benzene," Baer said. "But at least half the cases are of unknown cause." She added that radiation treatments for other diseases are another suspected cause.The effects of aplastic anemia and MDS vary, depending on the type of blood cells lacking in the body, Baer said.Red blood cells carry oxygen, and a shortage of those will cause fatigue and shortness of breath. White blood cells fight infection, so when the body lacks those cells, it is more likely to catch infectious diseases. Platelets cause clotting, and without those, people experience nosebleeds, bleeding gums and extended bleeding from cuts.These diseases used to be killers, fatal within a year, said Dr. Richard Stone, clinical director of the Adult Leukemia Program at Harvard University's Dana-Farber Cancer Institute and an associate professor at Harvard Medical School."Now, people can be expected to live a long time in many cases," Stone said. "It's devastating if untreated but quite approachable if treated."Baer and Stone said that while no breakthrough treatments have been developed, the available therapies are at the point where people can live with the disorders.Most people with aplastic anemia will require multiple blood transfusions, which relieve symptoms by providing blood cells that the bone marrow isn't producing, Baer said. Symptoms also can be managed with immunosuppressive drugs similar to those used in AIDS treatment. The drugs suppress the activity of immune cells that are damaging bone marrow, helping the marrow recover and generate new blood cells, she said.Antibiotics can be used to effectively fight off infections that take advantage of the disorder. And for a longer-term therapy -- or for people with severe aplastic anemia -- bone marrow transplantation is an option, but a limited one due to the difficulty involved in finding a matching donor.Experimental treatments now being tested include growth factor drugs that may help stimulate the bone marrow to pro male hormones that also might boost b and peripheral stem cell transplants. In that procedure, stem cells are taken from the blood of a donor, rather than from their own bone marrow, and transplanted into the patient, according to the Mayo Clinic."Twenty, 30 years ago, it [aplastic anemia] was fatal," Baer said. "Now, between the different treatments, 70 to 90 percent can live a long life. You have to continue to monitor your blood counts, and you are on some medication long-term."Since these diseases involve damage to stem cells, research in this area could provide much insight into the potential of stem cells for treating other types of diseases. Stem cells have attracted much research focus due to their potential regenerative powers and ability to transform themselves into a host of different cells.Bone marrow stem cells are the most primitive cells in the marrow, and from them, all the various types of blood cells are descended. Research also has shown that stem cells from bone marrow can give rise to non-marrow cells, which has led to federal funding to look into their usefulness in treating heart disease."It's very important to understand as much as possible about the bone marrow stem cell," Stone said. "What keeps it going, what causes it to become malignant? The more we understand about those things, the more we'll know about potential uses of stem cells.">再生障碍性贫血：不再是不治之症。患有曾一度被视为不治之症的人，寿命正在不断延长。《每日健康》日，星期日据《每日健康》日新闻报道---再生障碍性贫血（再障），是一种骨髓造血功能紊乱的疾病，在美国非常罕见，据全国骨髓捐献者计划报道，其发病率仅百万分之三。尽管再障极少见，但却是致命的，不过当今医疗技术已大大提高，这种疾病的治疗情况已大为改善，患者生存时间明显延长，症状亦可明显缓解。有学者指出，深入的研究不仅有助于再障及其它骨髓疾病的治疗，对于这种疾病的理解还有助于提高科学家对心脏疾病及白血病等常见病的认识。再障是指骨髓不能产生足够的血细胞，再生障碍性贫血患者情报及MDS国际基金的专家Katherine Baer说，目前在全美国新发病倒仅1000例/年。骨髓增生异常综合征（MDS），是与再障相关的另一种血液病，是指骨髓几乎不能产生成熟的血细胞，甚至幼稚细胞，这种疾病年发病约例。Baer说这两种疾病的病因目前尚未完全明确。“只有部分情况下病因是明确的，像苯这类有毒性的化学物质就可以诱发血液病，”Baer说，“但至少一半以上的病人的发病病因是未知的。”她还指出，医疗性放射线也是一个不容忽视的因素。再障及MDS的临床症状个人差异极大，很大程度上取决于到底是哪一系的血细胞形成障碍。红细胞有携带氧气的功能，缺乏红细胞会出现乏力、呼吸短促的症状；白细胞的功能主要是抗感染，白细胞缺乏临床上就表现为易感染；而血小板的功能是凝血、止血，血小板低的病人常会有鼻衄、消化道出血及伤口出血不止等症状。在以往，确诊再障及MDS的病人的生存时间不足1年，Richard Stone医生说，他是Harvard大学Dana-Farbe肿瘤研究院成人白血病临床治疗负责人，也Harvard大学医学院的一名副教授。“现在，许多病人的期望生存时间都明显延长了，”Stone医生说，“（再障及MDS）如果不予治疗，后果是不堪设想的；但只要给予积极治疗，预后是良好的。”Baer和 Stone都认为，虽然（再障及MDS）临床治疗上没有大的突破，但目前的治疗措施足以保证患者达到无病生存的状态。再障患者的骨髓不能产生血细胞，但通过输血可以必需的血细胞，从而可以缓解症状，Baer解析。治疗艾滋病的一些免疫抑制剂也可用于治疗再障，这些药物可抑制对骨髓细胞有杀伤力的免疫细胞的活性，从而有助于骨髓造血功能的恢复，进而达到治疗目的。抗生素抗感染的疗效是明确的，一旦出现疾病（再障及MDS）本身继发的感染应及时使用抗生素。对于重型再障，可考虑采用根治性的治疗方案―骨髓移植，但因其要求必须找到相匹配的供者，故其应用受到严重限制。现正在进行试验的新治疗方法有：用生长因子刺激骨髓产生血细胞；用雄激素刺激骨髓产生血细胞；外周血干细胞移植。Mayo Clinic说，外周血造血干细胞移植所用的造血干细胞是从供者外周血采得，而不是从骨髓采得。“二三十年前，再障是一种非常致命的疾病，”Baer说，“现在，由于各种治疗方案的使用，有70-90%的病人可以获得长期存活，而病人需要做的仅是持续监测自己的血细胞计数及长期服药。”由于疾病（再障及MDS）的发生涉及造血干细胞的损伤，因此相关领域的研究将会为干细胞治疗在其它疾病的应用提供思路。因干细胞可以自我复制及分化为各种不同的细胞，干细胞相关研究吸引了越来越多科学家的关注。骨髓干细胞是骨髓里最原始的细胞，各系血细胞都由其分化而来。研究还发现，骨髓干细胞还可能产生非骨髓细胞，联邦基金会正计划资助相关研究，以探讨其在心脏病治疗的应用。“全面地认识骨髓干细胞意义重大，”Stone说，“是什么因素使造血干细胞能够维持正常的自身复制，又是什么原因使之恶变，对其中的机制认识得越透彻，干细胞潜能的开发就越全面。”[/color][color=Red]最后这一句还要请教各位战友:"What keeps it going, what causes it to become malignant? The more we understand about those things, the more we'll know about potential uses of stem cells."谢谢啦,多多提供自己的意见!!Good！a patient information specialist for the Aplastic Anemia and MDS International Foundation Inc 再生障碍性贫血患者情报及MDS国际基金的专家a patient information specialist for the International Foundation for Aplastic Anemia and MDS bleeding gums

A method of replacing blood-forming cells destroyed by cancer treatment. Immature blood cells (stem cells) in the circulating blood that are similar to those in the bone marrow are given to the patient after treatment. This helps the bone marrow recover and continue producing healthy blood cells. Transplantation may be autologous (an individual's own blood cells saved earlier), allogeneic (blood cells donated by someone else), or syngeneic (blood cells donated by an identical twin). Also called peripheral stem cell support. How are PBSCs obtained for transplantation? The stem cells used in PBSCT come from the bloodstream. A process called apheresis or leukapheresis is used to obtain PBSCs for transplantation. For 4 or 5 days before apheresis, the donor may be given a medication to increase the number of stem cells released into the bloodstream. In apheresis, blood is removed through a large vein in the arm or a central venous catheter (a flexible tube that is placed in a large vein in the neck, chest, or groin area). The blood goes through a machine that removes the stem cells. The blood is then returned to the donor and the collected cells are stored. Apheresis typically takes 4 to 6 hours. The stem cells are then frozen until they are given to the recipient.apheresis：A procedure in which blood is collected, part of the blood such as platelets or white blood cells is taken out, and the rest of the blood is returned to the donor. Also called pheresis.leukapheresis：Removal of the blood to collect
the remaining blood is returned to the body.Are any risks associated with donating PBSCs?Apheresis usually causes minimal discomfort. During apheresis, the person may feel lightheadedness, chills, numbness around the lips, and cramping in the hands. Unlike bone marrow donation, PBSC donation does not require anesthesia. The medication that is given to stimulate the release of stem cells from the marrow into the bloodstream may cause bone and muscle aches, headaches, fatigue, nausea, vomiting, and/or difficulty sleeping. These side effects generally stop within 2 to 3 days of the last dose of the medication.翻译得很专业，语句也很通顺。以下为小小建议，仅供参考。1.

Only about 1,000 new cases appear each year in the United States.为再生障碍性贫血和MDS国际基金会工作的病人信息方面的专家Katherine Baer说，再障是由于骨髓不能产生足够的血细胞。美国每年仅有1000例新发病例。A related blood disorder, myelodysplastic syndromes, or MDS, occurs when the bone marrow begins producing poorly functioning or immature blood cells. About 20,000 to 30,000 new cases occur each year.骨髓增生异常综合症（MDS）也是一种血液相关的疾病，是由于骨髓产生非成熟或无功能的血细胞。美国每年新发病例大约为。Doctors still aren't certain exactly what causes the diseases' onset, Baer said."They do th there are some toxins that may cause it, like benzene," Baer said. "But at least half the cases are of unknown cause." She added that radiation treatments for other diseases are another suspected cause.Baer说，医生一直不能确切的断定本病的病因。她说：“医生可以确定本病病因为某些毒性化合物如苯，但是有一半的病例病因未明”她补充道，放射治疗其他疾病是另一种可能的病因。The effects of aplastic anemia and MDS vary, depending on the type of blood cells lacking in the body, Baer said.Baer说，再生障碍性贫血和MDS的对身体的影响取决于体内缺乏的血细胞种类。Red blood cells carry oxygen, and a shortage of those will cause fatigue and shortness of breath. White blood cells fight infection, so when the body lacks those cells, it is more likely to catch infectious diseases. Platelets cause clotting, and without those, people experience nosebleeds, bleeding gums and extended bleeding from cuts.红细胞具有携氧功能，红细胞缺乏会引起呼吸急促和疲乏。白细胞具有抗感染功能，所以当体内缺乏白细胞时，机体更易感染。血小板具有凝血功能，缺乏血小板会引起鼻出血，牙龈出血和伤口出血不止。These diseases used to be killers, fatal within a year, said Dr. Richard Stone, clinical director of the Adult Leukemia Program at Harvard University's Dana-Farber Cancer Institute and an associate professor at Harvard Medical School.哈佛大学Dana-Farbe癌症机构成人白血病规划组临床主任兼哈佛医学院教授Richard Stone博士 说，这些疾病一年内常会导致病人死亡"Now, people can be expected to live a long time in many cases," Stone said. "It's devastating if untreated but quite approachable if treated."Stone说：“现在，许多病人都渴望能够生存的更久，但是通过治疗的确可以生存的更久，而不治疗病情将很快恶化。Baer and Stone said that while no breakthrough treatments have been developed, the available therapies are at the point where people can live with the disorders.Baer and Stone说，目前还没有根治的突破性进展，有效地治疗也就是病人带病生存Most people with aplastic anemia will require multiple blood transfusions, which relieve symptoms by providing blood cells that the bone marrow isn't producing, Baer said. Symptoms also can be managed with immunosuppressive drugs similar to those used in AIDS treatment. The drugs suppress the activity of immune cells that are damaging bone marrow, helping the marrow recover and generate new blood cells, she said.Baer说，大部分再障病人需要多次输血来提供骨髓不能产生的血细胞来缓解症状。也能够用治疗AIDS相似的免疫抑制药物来控制症状，这些免疫抑制剂能够抑制免疫细胞对骨髓的损害，帮助骨髓恢复和产生新的血细胞。Antibiotics can be used to effectively fight off infections that take advantage of the disorder. And for a longer-term therapy -- or for people with severe aplastic anemia -- bone marrow transplantation is an option, but a limited one due to the difficulty involved in finding a matching donor.抗生素能够有效地控制感染，骨髓移植对于需要长期治疗和重型再障的病人是一个很好的选择，但是由于很难找到合适的配型供体而限制了其应用。Experimental treatments now being tested include growth factor drugs that may help stimulate the bone marrow to pro male hormones that also might boost b and peripheral stem cell transplants.

Stem cells have attracted much research focus due to their potential regenerative powers and ability to transform themselves into a host of different cells.由于本病损害干细胞，在这个领域的研究能提供更多用干细胞治疗其他疾病的可能。由于干细胞的自我增殖和多向分化的能力已经引起了更多的研究在这个领域。Bone marrow stem cells are the most primitive cells in the marrow, and from them, all the various types of blood cells are descended. Research also has shown that stem cells from bone marrow can give rise to non-marrow cells, which has led to federal funding to look into their usefulness in treating heart disease.骨髓干细胞是骨髓中最多的原始细胞，能够转化为各种血细胞，研究表明骨髓干细胞能产生非髓系细胞，联邦基金已经开始用于其对心脏病的研究。"It's very important to understand as much as possible about the bone marrow stem cell," Stone said. "What keeps it going, what causes it to become malignant? The more we understand about those things, the more we'll know about potential uses of stem cells."Stone博士说：“尽可能的了解骨髓干细胞很重要，是什么使它自我增殖和分化，是什么又使它转化恶性？我们对这些明白的越多，我们越能够知道如何去更好的利用干细胞。The effects of aplastic anemia and MDS vary, depending on the type of blood cells lacking in the body, Baer said.再障及MDS的临床症状个人差异极大，很大程度上取决于到底是哪一系的血细胞形成障碍。个体差异These diseases used to be killers, fatal within a year在以往，确诊再障及MDS的病人的生存时间不足1年，再障和MDS在过去常被认为是“杀手”，患者的生存时间不到1年。Baer and Stone said that while no breakthrough treatments have been developed, the available therapies are at the point where people can live with the disorders.Baer和 Stone都认为，虽然（再障及MDS）临床治疗上没有大的突破，但目前的治疗措施足以保证患者达到无病生存的状态。试译：Baer和 Stone都认为，虽然再障及MDS的治疗没有突破性进展，但目前的治疗措施足以延长患者的生存时间。And for a longer-term therapy -- or for people with severe aplastic anemia -- bone marrow transplantation is an option, but a limited one due to the difficulty involved in finding a matching donor.对于重型再障，可考虑采用根治性的治疗方案―骨髓移植，但因其要求必须找到相匹配的供者，故其应用受到严重限制。but a limited one due to the difficulty involved in finding a matching donor.但由于难以找到相匹配的供体，故其应用受到限制。radiation treatments for other diseases are another suspected cause.医疗性放射线也是一个不容忽视的因素。针对其他疾病的放射治疗是另一个可能原因。papertigerhu老师的翻译更加忠于原文,但又不拘泥于原文,语句更加流畅,又简洁!!我把几个人的翻译都放在一起比较,方便战友学习.谢谢papertigerhu及蓝色幻想老师的点评!!1、is a rare disorder in the United States.
