    一名46岁的女性患有特纳综合征(TS)(45,X/46,X,idic(X)(p11.4)马赛克)出现发烧,反应迟钝,多汗症,在混乱和自杀未遂事件发生大约一个月后,提示精神分裂症的诊断。脑脊液(CSF)显示轻度细胞过多,具有寡克隆带。脑和腹部磁共振成像未见异常。阿昔洛韦的试验给药后出现了奇怪的上肢运动和痉挛,怀疑是自身免疫性脑炎。开始强化免疫疗法,症状有所改善。抗N-甲基-D-天冬氨酸受体(抗NMDAR)脑炎是根据脊髓液中存在抗NMDAR抗体来诊断的。该病例代表了TS中抗NMDAR脑炎的罕见表现,易受自身免疫性疾病并发症的影响。
    A 46-year-old woman with Turner syndrome (TS) (45,X/46,X,idic (X) (p11.4) mosaic) presented with a fever, unresponsiveness, hyperhidrosis, and rigidity approximately one month after episodes of confusion and suicide attempts, prompting a diagnosis of schizophrenia. Cerebrospinal fluid (CSF) showed mild hypercellularity with oligoclonal bands. Brain and abdominal magnetic resonance imaging showed no abnormalities. Bizarre upper-extremity movements and spasms followed the trial administration of acyclovir, and autoimmune encephalitis was suspected. Intensive immunotherapy was initiated, and the symptoms improved. Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis was diagnosed based on the presence of anti-NMDAR antibodies in her spinal fluid. This case represents a rare presentation of anti-NMDAR encephalitis in TS, which is susceptible to autoimmune disease complications.

    乳糜泻(CD)是一种全身性自身免疫性疾病,由遗传易感个体的麸质摄入引发,其特征是临床表现多样。尽管流行,由于其异质性症状和意识不足,CD通常仍未被诊断。这里,我们介绍一例42岁男性胃炎患者,表现为上腹部不适和全血细胞减少症。初步调查显示血红蛋白水平为3.7g/dL,平均红细胞体积(MCV)为84fL,白细胞计数(WBC)为2420个细胞/μL,中性粒细胞计数(NEU)为1400个细胞/μL,和140,000个细胞/μL的血小板计数(PLT)。诊断检查显示了CD的证据,之后,诊断通过胃结肠镜检查得到证实.患者随后坚持无麸质饮食导致显著的临床改善。值得注意的是,在后续预约期间,观察到患者头发颜色的显著变化,促使进一步调查。患者报告说,在他三十多岁的时候,头发过早变白,在诊断为CD和开始无麸质饮食之前一直保持不变。这种独特的表现突出了CD和头发过早变白之间的潜在联系,保证进一步调查。虽然确切的机制尚不清楚,CD引起的吸收不良和营养缺乏可能导致这种变化。因此,我们主张提高认识和国际合作,以增进对这一现象及其对裁谈会管理的影响的理解。该病例强调了早期诊断和治疗CD的重要性,以及饮食干预减轻相关症状和并发症的潜力。
    Celiac disease (CD) is a systemic autoimmune disorder triggered by gluten ingestion in genetically predisposed individuals and characterized by diverse clinical presentations. Despite its prevalence, CD often remains undiagnosed due to its heterogeneous symptoms and inadequate awareness. Here, we present a case of a 42-year-old male with gastritis who presented with epigastric discomfort and pancytopenia. Initial investigations revealed a hemoglobin level of 3.7 g/dL, a mean corpuscular volume (MCV) of 84 fL, a white blood cell count (WBC) of 2420 cells/μL, a neutrophil count (NEU) of 1400 cells/μL, and a platelet count (PLT) of 140,000 cells/μL. A diagnostic workup revealed evidence of CD, and after that, the diagnosis was confirmed by gastro-colonoscopy. The patient\'s subsequent adherence to a gluten-free diet resulted in significant clinical improvement. Notably, during follow-up appointments, a notable change in the patient\'s hair color was observed, prompting further inquiry. The patient reported experiencing premature graying of hair during his late thirties, which remained unchanged until the diagnosis of CD and the initiation of a gluten-free diet. This unique manifestation highlights the potential association between CD and premature graying of the hair, warranting further investigation. While the precise mechanism remains unclear, it is plausible that CD-induced malabsorption and nutritional deficiencies may contribute to such changes. Therefore, we advocate for increased awareness and international collaboration to enhance understanding of this phenomenon and its implications for CD management. This case underscores the importance of early diagnosis and management of CD, as well as the potential for dietary interventions to alleviate associated symptoms and complications.

    我们研究了在高度上皮性卵巢癌诊断后发展自身免疫性疾病(AID)是否可以改善总体生存率。这项回顾性研究包括了接受高级别浆液性治疗的女性的数据,子宫内膜样,或移行细胞卵巢,输卵管,或瑞士州妇科癌症中心的腹膜癌FIGOIII或IV期(2008-2023年)。我们使用Kaplan-Meier估计和Cox比例风险模型,使用时变协变量进行生存函数估计。总之,128名患者中有9名在癌症诊断后发展为AID。从癌症诊断到AID的中位时间为2年(IQR2-5)。这些妇女的中位存活时间为3031天(IQR1765-3963),而未发生AID的妇女的中位存活时间为972天(IQR568-1819)(p=0.001)。9名预先存在AID的女性的中位总生存期为1093天(IQR716-1705),类似于那些从未获得援助的人。多变量分析显示年龄较大(p=0.003,HR1.04,95%CI1.013-1.064)与预后较差相关,并且在癌症诊断后发生AID与更长的生存期相关(p=0.033,HR0.113,95%CI0.015-0.837)。卵巢癌诊断后自身免疫性疾病的临床表现与更好的总生存期(8年对2.7年)相关。表明过度活跃的免疫反应可能会改善癌症控制。
    We investigated whether developing an autoimmune disorder (AID) following a high-grade epithelial ovarian cancer diagnosis improves overall survival. This retrospective study included data from women treated for high-grade serous, endometrioid, or transitional cell ovarian, fallopian tube, or peritoneal cancer FIGO stage III or IV at a Swiss cantonal gynecological cancer center (2008-2023). We used Kaplan-Meier estimates and the Cox proportional hazards model using time-varying covariates for the survival function estimation. In all, 9 of 128 patients developed an AID following a cancer diagnosis. The median time from cancer diagnosis to AID was 2 years (IQR 2-5). These women survived for a median of 3031 days (IQR 1765-3963) versus 972 days (IQR 568-1819) for those who did not develop an AID (p = 0.001). The median overall survival of nine women with a pre-existing AID was 1093 days (IQR 716-1705), similar to those who never had an AID. The multivariate analyses showed older age (p = 0.003, HR 1.04, 95% CI 1.013-1.064) was associated with a poorer prognosis, and developing an AID after a cancer diagnosis was associated with longer survival (p = 0.033, HR 0.113, 95% CI 0.015-0.837). Clinical manifestations of autoimmune disorders following ovarian cancer diagnoses were associated with better overall survival (8 versus 2.7 years), indicating an overactive immune response may improve cancer control.

    背景:乳糜泻(CeD)是一种由遗传易感个体对谷蛋白的免疫反应引发的自身免疫性疾病。最近的研究揭示了发生特定恶性肿瘤(MN)和各种恶性肿瘤的风险增加,包括胃肠,淋巴瘤,皮肤,和其他人,在与CeD的个人。
    目的:调查美国住院CeD患者中MN的患病率。
    方法:使用来自全国住院患者样本的数据,从2000年1月到2019年12月,我们确定了529842例CeD患者,其中78128人(14.75%)患有MN。倾向得分匹配,根据年龄,性别,种族,和日历年,以1:1的比例比较CeD患者和一般非CeD人群。
    结果:观察到一些恶性肿瘤呈正相关,包括小肠,淋巴瘤非黑色素瘤皮肤,肝脏,黑色素瘤皮肤,胰腺骨髓增生异常综合征,胆道,胃,和其他神经内分泌肿瘤(不包括小肠和大肠恶性类癌),白血病,子宫,和睾丸。相反,CeD患者出现呼吸道和继发性恶性肿瘤的风险降低。此外,某些恶性肿瘤与CeD无关联,包括头部和颈部,神经系统,食道,结直肠,肛门,乳房,恶性类癌,骨骼和结缔组织,骨髓瘤,子宫颈,和卵巢癌。
    结论:我们的研究是独一无二的,负,不同血液学和实体恶性肿瘤与CeD之间的关联或无效。此外,它提供了对CeD医院结果演变趋势的见解,揭示了过去二十年来其管理方面的进步。这些发现有助于理解CeD对健康和医疗保健利用的影响。
    BACKGROUND: Celiac disease (CeD) is an autoimmune disorder triggered by the immune response to gluten in genetically predisposed individuals. Recent research has unveiled a heightened risk of developing specific malignant neoplasms (MN) and various malignancies, including gastrointestinal, lymphomas, skin, and others, in individuals with CeD.
    OBJECTIVE: To investigate the prevalence of MN in hospitalized CeD patients in the United States.
    METHODS: Using data from the National Inpatient Sample spanning two decades, from January 2000 to December 2019, we identified 529842 CeD patients, of which 78128 (14.75%) had MN. Propensity score matching, based on age, sex, race, and calendar year, was employed to compare CeD patients with the general non-CeD population at a 1:1 ratio.
    RESULTS: Positive associations were observed for several malignancies, including small intestine, lymphoma, nonmelanoma skin, liver, melanoma skin, pancreas myelodysplastic syndrome, biliary, stomach, and other neuroendocrine tumors (excluding small and large intestine malignant carcinoid), leukemia, uterus, and testis. Conversely, CeD patients exhibited a reduced risk of respiratory and secondary malignancies. Moreover, certain malignancies showed null associations with CeD, including head and neck, nervous system, esophagus, colorectal, anus, breast, malignant carcinoids, bone and connective tissues, myeloma, cervix, and ovary cancers.
    CONCLUSIONS: Our study is unique in highlighting the detailed results of positive, negative, or null associations between different hematologic and solid malignancies and CeD. Furthermore, it offers insights into evolving trends in CeD hospital outcomes, shedding light on advancements in its management over the past two decades. These findings contribute valuable information to the understanding of CeD\'s impact on health and healthcare utilization.

    特发性血小板减少性紫癜(ITP)的特征是持续的低血小板计数,这可能导致严重出血,如胃炎和出血性中风。ITP中自身抗体的形成导致血小板破坏增加,然后阻碍造血。皮质类固醇和静脉注射免疫球蛋白是用于ITP的常见治疗方法,但是它们有明显的副作用。这是一例27岁女性ITP患者贫血的病例报告,血小板减少性,初次接受romiplostim治疗后卵巢囊肿破裂。病人从液体复苏中受益,输血,和皮质类固醇治疗;然后,病人的病情好转了。这个案例突出了与管理ITP相关的并发症,强调通过定期监测个性化治疗方案的重要性,以改善获益和风险的平衡,从而为患有ITP的慢性患者提供了综合治疗。
    Idiopathic thrombocytopenic purpura (ITP) is characterized by a persistently low platelet count, which can lead to serious bleeding such as gastritis and hemorrhagic stroke. The formation of auto-antibodies in ITP leads to increased destruction of platelets and then hampers hematopoiesis. Corticosteroids and intravenous immunoglobulin are among the common treatments used for ITP, but they have significant side effects. This is a case report of a 27-year-old woman with ITP who was found to be anemic, thrombocytopenic, and had a ruptured ovarian cyst after the initial romiplostim therapy. The patient benefited from fluid resuscitation, blood transfusion, and corticosteroid therapy; then, the patient\'s condition improved. This case highlights the complications associated with managing ITP, emphasizing the importance of personalizing therapy regimens through regular monitoring to improve the balance of benefits and risk, resulting in a comprehensive treatment for chronic patients suffering from ITP.

    未分化结缔组织病(UCTD)由于其广泛的临床表现和缺乏特定的诊断标准而提出了重大的诊断挑战。我们介绍了一名22岁的女性,她最初表现出类似普通流感的症状,包括反复发烧,头痛,和体质症状。尽管最初的测试显示没有异常和自身免疫血清学阴性,她的症状持续存在,促使进一步调查。尽管随后的影像学研究没有得到明确的诊断,最初阴性结果后,她的炎症标志物升高和抗核抗体(ANA)测试逐渐阳性,提示潜在的自身免疫过程。经过六个月的持续症状,由风湿病学家开始的羟氯喹治疗使她的症状得到了显着缓解。这个案例凸显了诊断UCTD的挑战,特别是在年轻人中,症状可能在生命早期出现,没有明显的实验室异常,有时初始ANA为阴性,使其成为一个学习点,重新检查ANA水平,即使他们最初是负的。它强调了在症状不明和实验室检查结果不确定的患者中考虑UCTD的重要性。因为早期开始适当的治疗可以显着缓解症状并改善患者预后。
    Undifferentiated connective tissue disease (UCTD) poses a significant diagnostic challenge due to its wide array of clinical presentations and the absence of specific diagnostic criteria. We present the case of a 22-year-old female who initially exhibited symptoms resembling the common flu, including recurrent fever, headaches, and constitutional symptoms. Despite initial tests showing no abnormalities and negative autoimmune serology, her symptoms persisted, prompting further investigation. Although subsequent imaging studies yielded no definitive diagnosis, her elevated inflammatory markers and progressively positive antinuclear antibody (ANA) test after the initial negative result suggested an underlying autoimmune process. After six months of persistent symptoms, treatment with hydroxychloroquine initiated by a rheumatologist led to a remarkable resolution of her symptoms. This case highlights the challenge of diagnosing UCTD, particularly in young individuals, where symptoms may manifest early in life without clear laboratory abnormalities, sometimes with initial negative ANA, making it a learning point to recheck ANA levels even if they were initially negative. It underscores the importance of considering UCTD in patients with unexplained symptoms and inconclusive laboratory findings, as early initiation of appropriate treatment can significantly alleviate symptoms and improve patient outcomes.

    Tolosa-Hunt综合征(THS),也被称为疼痛性眼肌麻痹,复发性眼肌麻痹,或眼肌麻痹综合征,被描述为与疼痛和受限的眼球运动相关的严重和单侧眶周头痛。由于海绵窦的肉芽肿性炎症,THS是一种罕见的疾病。虽然THS主要是特发性的,很少有与系统性红斑狼疮(SLE)相关的报道.本病例报告描述了作为SLE最初表现的THS的独特病例,多系统自身免疫性疾病.我们提供了一个54岁的女性患者的详细病例报告,该患者患有THS,具有THS的经典症状,包括单侧头痛,双重视觉,和眼眶疼痛。颅神经检查显示右动眼神经麻痹,无法加合物,提高,或者压抑她的右眼.详细的临床检查显示,她的右耳垂有斑秃和红斑性黄斑病变。除了红细胞沉降率(ESR)增加外,实验室检查均无明显变化。诊断性调查,包括MRI和血清学检查,进行了探索根本原因和系统参与。患者的MRI显示与THS一致的特征性发现,而血清学检测显示抗核抗体阳性,抗ds-DNA抗体,以及抗Smith抗体和低补体水平导致SLE的并发诊断。在出现时没有其他系统性狼疮表现。用大剂量皮质类固醇治疗导致眼部症状和头痛的快速改善。开始维持免疫抑制治疗以治疗SLE。患者在随访中没有复发。该病例报告强调THS是SLE的潜在初始表现。它强调了对非典型颅神经病变患者进行全面诊断评估的必要性,以考虑系统性自身免疫性疾病如SLE。早期诊断和管理对于改善这种交织的病理的结果至关重要。这种情况强调临床医生需要意识到THS作为SLE的最初表现的可能性。这个扩展的摘要提供了文章的全面概述,阐述了该病例在扩大对局部炎症综合征和系统性自身免疫性疾病如SLE之间重叠的临床理解方面的意义。
    Tolosa-Hunt syndrome (THS), also known as painful ophthalmoplegia, recurrent ophthalmoplegia, or ophthalmoplegia syndrome, is described as severe and unilateral peri-orbital headaches associated with painful and restricted eye movements. THS is an uncommon disorder due to granulomatous inflammation of the cavernous sinus. Although THS is primarily idiopathic, it has rarely been reported in association with systemic lupus erythematosus (SLE). This case report describes a unique case of THS presenting as the initial manifestation of SLE, a multi-system autoimmune disease. We present a detailed case report of a 54-year-old female patient who presented with THS with the classical symptoms of THS including unilateral headache, double vision, and orbital pain. A cranial nerve examination revealed right oculomotor nerve palsy with the inability to adduct, raise, or depress her right eye. A detailed clinical examination revealed alopecia areata and erythematous macular lesions on her right earlobe. Laboratory investigations were unremarkable except for an increased erythrocyte sedimentation rate (ESR). Diagnostic investigations, including MRI and serological tests, were conducted to explore the underlying causes and systemic involvement. The patient\'s MRI showed characteristic findings consistent with THS, while serological tests revealed positive antinuclear antibodies, anti-ds-DNA antibodies, and anti-Smith antibodies and low complement levels leading to a concurrent diagnosis of SLE. There were no other systemic manifestations of lupus at the time of presentation.  Treatment with high-dose corticosteroids led to rapid improvement in ocular symptoms and headaches. Maintenance immunosuppressive therapy was initiated for the management of SLE. The patient had no relapses on follow-up. This case report underscores THS as a potential initial manifestation of SLE. It highlights the need for comprehensive diagnostic evaluation in patients presenting with atypical cranial neuropathy to consider systemic autoimmune disorders like SLE. Early diagnosis and management are crucial for improving outcomes in such intertwined pathologies. This case emphasizes the need for clinicians to be aware of the possibility of THS as the initial manifestation of SLE. This extended abstract provides a comprehensive overview of the article, laying out the significance of the case in broadening the clinical understanding of the overlap between localized inflammatory syndromes and systemic autoimmune conditions like SLE.

    类风湿性关节炎(RA)是一种慢性,以疼痛为特征的对称性炎症性自身免疫性疾病,肿胀的滑膜炎和关节糜烂,这可能会导致骨骼和软骨的损伤,并与进行性残疾有关。尽管扩大了治疗选择,一些患者仍然出现反应不足或无法忍受的不良反应。因此,RA的治疗选择仍然相当有限.AKT1酶对于设计各种人类疾病的药物至关重要,支持细胞功能,如增殖,生存,新陈代谢,正常和恶性细胞的血管生成。因此,AKT丝氨酸/苏氨酸激酶1被认为对于靶向旨在缓解RA机制的治疗策略至关重要。在这种情况下,针对AKT1的努力代表了开发新的抗关节炎药物的创新方法.这项研究的主要目的是使用诸如分子建模和动力学模拟(MDS)和基于形状的虚拟筛选(SBVS)等计算技术对AKT1抑制剂进行优先级排序。通过筛选源自ChemDiv和IMPPAT数据库的化合物库,采用组合的SBVS方法来预测针对AKT1的有效抑制剂。从SBVS结果来看,只有前三个化合物,ChemDiv_7266、ChemDiv_2796和ChemDiv_9468基于它们的高结合亲和力和有利的ADME/Tox性质进行稳定性分析。SBVS的研究结果表明,关键残基,包括Glu17,Gly37,Glu85和Arg273,显着有助于在AKT1的活性位点成功结合最高等级的前导化合物。这种见解有助于理解这些导线在抑制RA中的特定结合机制,促进更有效治疗剂的合理设计。
    Rheumatoid Arthritis (RA) is a chronic, symmetrical inflammatory autoimmune disorder characterized by painful, swollen synovitis and joint erosions, which can cause damage to bone and cartilage and be associated with progressive disability. Despite expanded treatment options, some patients still experience inadequate response or intolerable adverse effects. Consequently, the treatment options for RA remain quite limited. The enzyme AKT1 is crucial in designing drugs for various human diseases, supporting cellular functions like proliferation, survival, metabolism, and angiogenesis in both normal and malignant cells. Therefore, AKT serine/threonine kinase 1 is considered crucial for targeting therapeutic strategies aimed at mitigating RA mechanisms. In this context, directing efforts toward AKT1 represents an innovative approach to developing new anti-arthritis medications. The primary objective of this research is to prioritize AKT1 inhibitors using computational techniques such as molecular modeling and dynamics simulation (MDS) and shape-based virtual screening (SBVS). A combined SBVS approach was employed to predict potent inhibitors against AKT1 by screening a pool of compounds sourced from the ChemDiv and IMPPAT databases. From the SBVS results, only the top three compounds, ChemDiv_7266, ChemDiv_2796, and ChemDiv_9468, were subjected to stability analysis based on their high binding affinity and favorable ADME/Tox properties. The SBVS findings have revealed that critical residues, including Glu17, Gly37, Glu85, and Arg273, significantly contribute to the successful binding of the highest-ranked lead compounds at the active site of AKT1. This insight helps to understand the specific binding mechanism of these leads in inhibiting RA, facilitating the rational design of more effective therapeutic agents.
