    Anamorelin(ANAM)是一种新型的ghrelin受体激动剂,用于治疗癌症恶病质。在ANAM的临床试验中,葡萄糖代谢紊乱作为不良反应相对频繁,然而,它们何时以及如何发生尚不清楚。此外,胰腺癌和/或糖尿病患者的安全性尚未得到澄清,因为之前的大多数研究都集中在非小细胞肺癌患者,并排除了糖尿病控制不佳的患者.在这里,一名患有晚期胰腺癌和糖尿病的66岁男子接受了ANAM治疗,并发展为急性高血糖,可以通过自我血糖监测(SMBG)进行监测。增加胰岛素剂量未能充分控制高血糖,但ANAM停药后高血糖迅速改善.连续葡萄糖监测(CGM)显示,尽管使用了1.5倍以上的胰岛素,但在ANAM给药期间,传感器葡萄糖水平全天仍保持在较高的范围内。我们的报告是描述ANAM诱导的高血糖的细节的少数报告之一,并为安全有效地使用ANAM提供了重要信息。
    Anamorelin (ANAM) is a novel ghrelin receptor agonist for the treatment of cancer cachexia. In clinical trials of ANAM, glucose metabolism disorders as adverse effects were relatively frequent, however, when and how they occur remains unclear. Moreover, the safety in patients with pancreatic cancer and/or diabetes has not been clarified because most previous studies focused on patients with non-small cell lung cancer and had excluded patients with poorly controlled diabetes. Herein, a 66-year-old man with advanced pancreatic cancer and diabetes was administered ANAM, and acute hyperglycemia was developed and could be monitored by the self-monitoring of blood glucose (SMBG). Increasing the insulin dose failed to control hyperglycemia adequately, but the hyperglycemia ameliorated quickly after ANAM discontinuation. The continuous glucose monitoring (CGM) revealed that the sensor glucose levels had remained in the high range throughout the day during ANAM administration despite using 1.5 times more insulin. Our report is one of the few that describe the details of ANAM-induced hyperglycemia and provides important information for the safe and effective use of ANAM.

    血小板减少是造血干细胞移植(HSCT)后可发生的常见且严重的并发症。它有助于增加发病率和死亡率。HSCT后血小板减少症的机制是多因素和复杂的。对于HSCT后血小板减少症的管理没有明确的共识和指南。最近,血小板生成素受体激动剂(TPO-RA)的应用前景广阔,特别是埃特罗波帕格和romiplostim,作为HSCT后血小板减少症的治疗。值得注意的是,这个指示被认为是标签外的,和数据在此使用是有限的。根据现有的证据,对于HSCT后输血依赖性血小板减少症患者,romiplostim是一种安全有效的选择。在这种情况下,我们总结了我们在一个中心的经验,其中romiplostim用于治疗由于移植物功能不良而导致的HSCT后血小板减少症。值得注意的是,所有四例对romiplostim治疗反应积极,并且没有观察到显著的不良事件。
    Thrombocytopenia is a common and serious complication that can occur following hematopoietic stem cell transplantation (HSCT), and it contributes to increased morbidity and mortality. The mechanisms of post-HSCT thrombocytopenia are multifactorial and complex. There are no clear consensus and guidelines for managing thrombocytopenia post-HSCT. Recently, there has been promising use of thrombopoietin receptor agonists (TPO-RAs), particularly eltrombopag and romiplostim, as treatments for post-HSCT thrombocytopenia. Notably, that this indication is considered off-label, and data in this use are limited. Based on the existing body of evidence, romiplostim emerges as a safe and effective option for individuals with transfusion-dependent thrombocytopenia after HSCT. In this context, we present a summary of our experience at a single center, where romiplostim was used in the management of post-HSCT thrombocytopenia due to poor graft function. Notably, all four cases responded positively to romiplostim treatment, and no significant adverse events were observed.

    背景:Eltrombopag,血小板生成素受体(TPO-R)激动剂,被认为是难治性免疫性血小板减少症(ITP)患者的二线治疗。系统性红斑狼疮(SLE)通常与ITP相关。在某些情况下,SLE患者的血小板减少症归因于并发抗磷脂抗体(APLA)。目前,关于SLE或APLA患者使用TPO-R激动剂治疗ITP的数据有限.在使用TPO-R激动剂时,SLE发作或抗磷脂综合征的发生率尚未得到充分研究。
    方法:我们报告2例女性SLE患者并发三阳性APLA,在他们的病史中没有血栓性事件,在我们的风湿病诊所,用艾曲波帕治疗难治性ITP。在开始使用eltrombopag治疗几周后,两者都出现了灾难性的抗磷脂综合征。他们被送进重症监护室接受solumedrol治疗,血浆置换,抗凝和利妥昔单抗。
    结论:我们描述了艾曲波帕的严重可能的副作用作为灾难性抗磷脂综合征的触发因素,一种罕见的抗磷脂综合征的初始表现,在患有APLA的SLE患者中。我们建议在SLE相关ITP患者开始使用eltrombopag之前测试APLA。在这些情况下,应考虑这种治疗的安全性。
    BACKGROUND: Eltrombopag, a thrombopoietin receptor (TPO-R) agonist, is considered a second-line treatment for patients with refractory immune thrombocytopenia (ITP). Systemic lupus erythematosus (SLE) is frequently associated with ITP. In some cases, thrombocytopenia in SLE patients is attributed to concurrent antiphospholipid antibodies (APLA). Currently, data regarding treatment with TPO-R agonists for ITP in SLE or APLA patients are limited. The incidence of SLE flare or antiphospholipid syndrome while on TPO-R agonists has not been well-studied.
    METHODS: We report 2 cases of female patients with SLE and concurrent triple positive APLA, without thrombotic events in their medical history, in our rheumatology clinic, who were treated for refractory ITP with eltrombopag. Both developed catastrophic antiphospholipid syndrome a few weeks after beginning treatment with eltrombopag. They were admitted to the intensive care unit and treated with solumedrol, plasmapheresis, anticoagulation and rituximab.
    CONCLUSIONS: We describe a severe possible side-effect of eltrombopag as a trigger of catastrophic antiphospholipid syndrome, a rare initial manifestation of antiphospholipid syndrome, in SLE patients with APLA. We suggest that APLA should be tested before initiating eltrombopag in patients with SLE-associated ITP. The safety of this treatment should be considered in these cases.

    背景技术许多治疗选择可用于患有多发性骨髓瘤(MM)的患者。由于疾病的进程,大多数患者将经历连续复发或MM将变得难以治疗这些治疗,随着时间的推移,患者几乎没有或没有治疗选择。Selinexor,具有新作用机制的治疗方法,是一种口服选择性核出口抑制剂(SINE)化合物,可阻断肿瘤抑制蛋白的主要核出口国出口蛋白1。案例报告在这个案例系列中,我们报道了来自阿根廷的3例患者每周口服selinexor联合硼替佐米和地塞米松(XVd)的治疗,这些患者接受了多次治疗(5~7例既往治疗),这些患者先前每次治疗均复发或难治.两名患者有高风险的细胞遗传学异常del(17p)。所有3名患者均具有XVd达到部分反应或非常好的部分反应的最佳反应的功效。这些反应与BOSTON研究中接受XVd治疗的患者一致,但预处理较少(1-3次先前治疗),并且自诊断为MM以来的中位时间较短(7年vs3.7年)。3例患者出现不良事件(AE),包括恶心,血小板减少症,虚弱,和疲劳,与最常见的与selinexor治疗相关的AE相似。结论口服给药,新的作用机制,以及严重预处理的患者的反应,selinexor可能有助于解决复发/难治性MM患者治疗的重要临床需求。
    BACKGROUND Numerous treatment options are available for patients with multiple myeloma (MM). Because of the course of the disease, most patients will experience serial relapse or the MM will become refractory to most of these treatments, leaving patients with few or no treatment options over time. Selinexor, a treatment with a novel mechanism of action, is an oral selective inhibitor of nuclear export (SINE) compound that blocks exportin 1, the major nuclear exporter of tumor suppressor proteins. CASE REPORT In this case series, we report on treatment with the weekly oral administration of selinexor combined with bortezomib and dexamethasone (XVd) in 3 patients from Argentina who were heavily treated (5-7 prior therapies) for MM that relapsed or was refractory to each previous treatment. Two patients had the high-risk cytogenetic abnormality del(17p). All 3 patients experienced efficacy with XVd reaching a best response of partial response or very good partial response. These responses were consistent with those of patients from the BOSTON study who were treated with XVd but were less heavily pretreated (1-3 prior therapies) and had a shorter median time since diagnosis of MM (7 years vs 3.7 years). The 3 patients experienced adverse events (AEs) that included nausea, thrombocytopenia, asthenia, and fatigue, which were similar to the most commonly reported AEs associated with selinexor treatment. CONCLUSIONS With its oral administration, novel mechanism of action, and responses in heavily pretreated patients, selinexor may help to address an important clinical need in the treatment of patients with relapsed/refractory MM.

    这项研究的目的是研究和评估植物疗法对常规治疗失败的严重和复杂的免疫性血小板减少症(ITP)患者的有效性。一名男性患者出现ITP的临床症状,并接受了皮质类固醇治疗,硫唑嘌呤,Eltrombopag,和血小板输注超过三年。患者最初有反应,但后来出现严重并发症,包括胸腔积液,胃痛,血尿,消化道出血,对治疗没有进一步的反应。然后,患者接受了17个月的植物治疗,显着改善了临床症状,血小板计数,和实验室测试。尽管他的生活方式很活跃,患者无症状,血小板计数范围为109至132×109/L。
    The purpose of this study was to investigate and evaluate the effectiveness of phytotherapy on a severe and complicated Immune Thrombocytopenia (ITP) patient who had failed with conventional treatments. A male patient presented with clinical symptoms of ITP and had been treated with Corticosteroids, Azathioprine, Eltrombopag, and platelet transfusions for over three years. The patient had an initial response but later developed severe complications, including hydrothorax, gastric pain, hematuria, and digestive hemorrhage, and no further response to treatment. The patient then received Phytotherapy for 17 months which significantly improved the clinical symptoms, platelet counts, and laboratory tests. Despite his active lifestyle, the patient was symptom-free with platelet counts ranging from 109 to 132×109/L.

    背景技术大约10%至15%的多发性骨髓瘤(MM)患者被诊断患有高风险疾病并且具有不良预后。临床试验数据支持联合使用selinexor,硼替佐米,和地塞米松(XVd)用于治疗已接受至少1次先前治疗的MM患者。有关XVd和随后的异基因干细胞移植(SCT)在高度预处理的高危MM患者中的疗效的信息有限。案例报告我们介绍了一名58岁的女性,患有高危MM(修订的国际分期系统III期;血清β2-微球蛋白;8.0mg/L;并且存在del[17p]),该女性接受了8个先前的治疗行,他的病是艾沙唑米难治的,硼替佐米,和所有的免疫调节剂.在开始XVd之前(每周一次,1.3mg/m²硼替佐米皮下,每个操作系统80毫克硒,和40毫克地塞米松/口),患者骨髓严重发育不良,并依赖输血.在XVd的1个循环之后,她得到了部分回应,在4个周期后,一个非常好的部分反应(VGPR)。没有观察到selinexor的不良反应。因为VGPR,计划进行单倍体移植。在移植后第4周,患者变得不依赖输血。她在开始XVd后13个月保持无复发。开始使用来那度胺进行维持治疗,并且由于供体嵌合状态的丧失而接受供体淋巴细胞输注后,患者的轻链水平得到改善。结论本报告介绍了接受SVd随后接受SCT治疗的高危MM患者的细胞遗传学和管理。
    BACKGROUND Approximately 10% to 15% of patients with multiple myeloma (MM) are diagnosed with high-risk disease and have poor prognosis. Clinical trial data supports the combined use of selinexor, bortezomib, and dexamethasone (XVd) for treatment of patients with MM who have received at least 1 prior therapy. Information on the efficacy of XVd and of subsequent allogeneic stem cell transplantation (SCT) in heavily pretreated patients with high-risk MM is limited. CASE REPORT We present a case of a 58-year-old woman with high-risk MM (revised International Staging System Stage III; serum ß₂-microglobulin; 8.0 mg/L; and presence of del[17p]) who had received 8 prior treatment lines, and whose disease was refractory to ixazomib, bortezomib, and all immunomodulatory agents. Before initiating XVd (once weekly 1.3 mg/m² bortezomib subcutaneously, 80 mg selinexor per os, and 40 mg dexamethasone per os), the patient had severely hypoplastic bone marrow and was transfusion dependent. After 1 cycle of XVd, she achieved a partial response, and after 4 cycles, a very good partial response (VGPR). No adverse reactions to selinexor were observed. Because of the VGPR, a haploidentical transplant was planned. At posttransplant week 4, the patient had become transfusion independent. She remained relapse-free for 13 months after initiating XVd. Maintenance treatment with lenalidomide was initiated, and following receipt of donor lymphocyte infusions due to loss of donor chimerism, the patient\'s light chain levels improved. CONCLUSIONS This report presents the cytogenetics and management of a heavily pretreated patient with high-risk MM treated with SVd followed by SCT.

    背景:继发性免疫性血小板减少性紫癜(ITP)也称为获得性血小板减少性紫癜,自身免疫性疾病通常是其重要病因之一。关于类风湿关节炎(RA)难治性血小板减少性紫癜的治疗报道很少。我们报告了一例难治性ITP,其中血小板相关标志物与治疗剂的变化值得临床医生关注。
    方法:一名69岁女性因颈部和手臂瘀斑入院15天。她5年前被诊断为RA。
    方法:诊断符合美国风湿病学会/欧洲抗风湿病联盟2010分类标准。疾病活动性评分28(DAS-28)为4.6,表明疾病活动性中等。
    方法:一线治疗和二线治疗——艾曲波帕(EPAG)治疗无效。因此,我们进行了利妥昔单抗联合低剂量EPAG治疗.
    结果:患者接受2个周期的利妥昔单抗联合EPAG,在随访期间,她的颊粘膜和四肢没有新的瘀斑。
    结论:本病例提示利妥昔单抗联合EPAG早期治疗对RA难治性ITP患者有益。在疾病动态监测方面,未成熟血小板分数(IPF)可能是预测疗效的辅助指标,但其意义有待进一步研究。
    BACKGROUND: Secondary immune thrombocytopenic purpura (ITP) is also known as acquired thrombocytopenic purpura, autoimmune disease is usually one of the important causes. There are few reports about treatment of refractory thrombocytopenic purpura in rheumatoid arthritis (RA). We report a case of refractory ITP in which changes in platelet-related markers with therapeutic agents are worthy of the attention of clinicians.
    METHODS: A 69-year-old woman admitted for ecchymosis on the neck and arms for 15 days presented to our hospital. She was diagnosed with RA 5 years ago.
    METHODS: The diagnosis met the American College of Rheumatology/European League Against Rheumatism 2010 classification criteria. The disease activity score 28 (DAS-28) was 4.6, indicating that the disease activity was moderate.
    METHODS: Treatment with first-line therapies and second-line treatment--eltrombopag (EPAG) were ineffective. Therefore, we performed rituximab combined with a low dose of EPAG.
    RESULTS: The patient received 2 cycles of rituximab combined with EPAG, and reported no new petechiae on her buccal mucosa and limbs during follow-up.
    CONCLUSIONS: This case suggests that early treatment of rituximab combined with EPAG is beneficial to patients with refractory ITP in RA. In terms of disease dynamic monitoring, immature platelet fraction (IPF) may be an auxiliary indicator for predicting efficacy, but its significance needs further study.

    背景:免疫性血小板减少性紫癜(ITP)是一种自身免疫性疾病,随着血小板的加速破坏,据估计,在欧盟,每年在100,000名成年人中影响1.6-3.9人。糖皮质激素和静脉内免疫球蛋白是常见的药物疗法。在难治性病例中,可以使用增强血小板生成的药物。Eltrombopag是一种血小板生成素受体激动剂,已知增加难治性ITP患者的血小板计数。已经描述了与Eltrombopag给药相关的血栓不良事件。
    方法:一名埃塞俄比亚血统的系统性红斑狼疮年轻女性患者,三联抗磷脂(APLA)阳性血清学和难治性ITP谁接受Eltrombopag和2周后发展为灾难性的APLA综合征与严重的Libman-Sacks二尖瓣和主动脉瓣心内膜炎,多个脑内侵犯和左上肢动脉血栓形成。
    结论:Eltrombopag是一种救助药物,用于难治性ITP。血栓不良事件,其中一些可能危及生命,是一种可能的并发症,尤其是高危患者。
    BACKGROUND: Immune thrombocytopenic purpura (ITP) is an autoimmune disease, with accelerated destruction of platelets, estimated to affect 1.6-3.9 in 100,000 adults every year in the European Union. Glucocorticoids and intravenous immunoglobulins are common drug therapies. In refractory cases, drugs that enhance thrombopoiesis may be used. Eltrombopag is a thrombopoietin receptor agonist, known to increase platelet count in patients with refractory ITP. Thrombotic adverse events have been described in association with Eltrombopag administration.
    METHODS: A young female patient of Ethiopian ancestry with systemic lupus erythematosus, triple Antiphospholipid (APLA) positive serology and refractory ITP who received Eltrombopag and 2 weeks later developed catastrophic APLA syndrome with severe Libman-Sacks endocarditis of the mitral and aortic valves, multiple intracerebral infracts and arterial thrombosis of the left upper limb.
    CONCLUSIONS: Eltrombopag is a salvage drug, used in refractory ITP. Thrombotic adverse events, some of which may be life-threatening, are a possible complication, especially in high-risk patients.

    原发性免疫性血小板减少症(ITP)是一种自身免疫性疾病,其特征是在没有其他原因或相关疾病的情况下,孤立的血小板减少症(血小板计数<100×109/l)。妊娠期ITP的发病率为每1000个妊娠1至2例。ITP可以在怀孕前或怀孕期间诊断;有时可以发生先前诊断的ITP的复发。静脉内免疫球蛋白(IVIg)和皮质类固醇是标准的一线治疗,因为它们对母亲或新生儿具有众所周知的安全性。难治性患者的治疗受到潜在胎儿风险的限制。我们报告了一名怀孕期间患有ITP的患者,皮质类固醇和IVIg难治性,成功治疗,血小板生成素受体激动剂(TPO-RA)艾曲波帕。患者几乎在整个怀孕期间接受了这种化合物,特别是在整个孕早期,对母亲和新生儿没有任何并发症。尽管TPO-RA在怀孕期间的短暂给药似乎具有良好的耐受性,它们在整个妊娠期间的使用仍然存在争议;这就是描述这种情况的原因,没有任何并发症,因此,它可以在这个领域添加有用的信息。
    Primary immune thrombocytopenia (ITP) is an autoimmune disorder characterized by isolated thrombocytopenia (platelet count <100 × 109/l) in the absence of other causes or disorders associated. The incidence of ITP in pregnancy is one to two cases per 1000 gestations. ITP could be diagnosed before or during pregnancy; sometimes a relapse of a previously diagnosed ITP can occur. Intravenous immune globulins (IVIg) and corticosteroids are the standard frontline therapy because of their well known safety profile either for the mother or for the neonate. Treatments for refractory patients are limited by potential fetal risk. We report the case of a patient with ITP along pregnancy, refractory to corticosteroids and IVIg, successfully treated with, the thrombopoietin receptor agonist (TPO-RA) eltrombopag. Patient received this compound for almost the whole pregnancy and in particular for the whole first trimester, without any complication for the mother and the neonate. Although transient administration of TPO-RAs in pregnancy seems to be well tolerated, their use during the whole gestation is still controversial; this is the reason of the description of this case, which did not show any complications, and thus it could add useful information on this field.
