Other treatments
If neither the initial round of corticosteroids nor a splenectomy has helped you achieve remission and your symptoms are severe, your doctor may recommend another course of corticosteroids, usually at the lowest effective dose.
Other possible treatments include:
• Immunosuppressant drugs. Medications that suppress the immune system, such as rituximab (Rituxan) — the most commonly used of this group — cyclophosphamide (Cytoxan) and azathioprine (Imuran, Azasan), have been used to treat ITP, but they can cause significant side effects, and their effectiveness has yet to be proved.
• Experimental drugs. New medications that increase platelet production, especially eltrombopag and AMG 531, are being studied in clinical trials. Although they appear to be well tolerated, questions about long-term side effects remain, and relapse is possible when the drugs are stopped.
• H. pylori treatment. Some people with ITP are also infected with Helicobacter pylori, the same bacteria that cause most peptic ulcers. Eliminating the bacteria has helped increase platelet count in some people, but the results for this therapy are inconsistent and need to be studied further.
Because of the potential complications of both the disease and its treatment, it's important for you and your doctor to carefully weigh the benefits and risks of treatment. For example, some people find that the side effects of treatment are more burdensome than the effects of the disease itself. Treatment decisions are usually based on:
• Severity of signs and symptoms (active bleeding is usually an indication for treatment)
• Platelet count — even relatively low counts (less than 30,000 platelets per microliter of blood) may not merit treatment, especially if you have no active bleeding and have a fairly sedentary lifestyle
• Your age and willingness to undergo treatment
• Risk of bleeding relative to lifestyle, such as participation in sports or other vigorous physical activities that may predispose you to injury
• Risk of bleeding based on other medical conditions (high blood pressure, infections, alcoholism, chronic liver disease, peptic ulcer) or needed medications, such as aspirin
• Potential side effects of ITP therapies
其它的治疗方案
如果经过最初一轮激素治疗跟脾切除术之后,并没有帮你减轻症状,并且你的症状仍然非常严重的话,你的医生可能会推荐你其它的一些激素治疗方案,而且通常是小剂量的。
其它可能的治疗方案包括:
• 免疫抑制药物 这些药物通常会抑制免疫系统,比如美罗华---在这组药物中最常用的---环磷酰胺和咪唑硫嘌呤,也已经被用来治疗ITP。但是它们会导致很明显的副作用,而且它们的疗效还有待验证。
• 实验药物 新的药物会增加血小板的产生,特别是伊屈泼帕和AMG531已经在临床实验中被研究。虽然它们看起来似乎是可以接受的,但存在的问题是长期服用的副作用和停药后复发的可能性。
• 幽门螺杆菌治疗 有些ITP患者也会同时感染幽门螺杆菌,同样的细菌可能会导致大多数的胃溃疡。消除这种细菌在某些特定人群中能帮助提高血小板的数量,但是这种疗法的结果是前后矛盾的,需要进一步的研究。
由于这种疾病和其治疗方案存在着潜在的并发症,你和你的医生权衡治疗方案的利与弊是非常重要的。例如有些人会发现治疗带来的副作用会比疾病本身更烦人。
治疗方案的决定通常依据于:
• 严重的迹象和症状(活动性出血往往是需要治疗的一个迹象)
• 血小板计数----即使相对比较少的计数(少于3万血小板每微升血液)可能都不值得治疗,尤其是如果你没有活动性出血并且有一种相当久坐不动的生活方式。(此处应该是说如果血小板比较少但是平时不怎么剧烈运动的话)
• 你的年龄和意愿能够承受治疗
• 出血的风险跟生活方式有关,比如参加一些运动或者其它一些可能会导致你受伤的剧烈的体育活动
• 出血的风险还基于其它的一些健康状况(高血压,传染病,酗酒,慢性肝病,消化性溃疡)或者服用的药物,比如阿司匹林
• ITP疗法潜在的副作用
