HTLV-I Infections

HTLV - I 感染
  • 文章类型: Case Reports
    在免疫抑制患者中同时出现副角菌病和圆线虫病,特别是那些感染人类嗜T淋巴细胞病毒1/2型,是罕见的。我们描述了来自中部丛林中的秘鲁农民患有人类T淋巴细胞病毒1/2型感染的情况,患有2个月的疾病,其特征是与发烧相关的呼吸道和胃肠道症状,减肥,淋巴结肿大.在痰液和支气管肺泡灌洗液样品中分离出赤圆圆线虫和巴西副球菌,分别。患者接受伊维菌素和两性霉素B后,临床进展良好。我们假设,在人类1/2型嗜T淋巴细胞病毒感染的患者中,胸骨链球菌的自身侵染可能有助于副球菌的传播。了解流行病学背景对于怀疑机会性区域感染至关重要,特别是那些可能共存于免疫抑制患者中的患者。
    Co-occurrence of paracoccidioidomycosis and strongyloidiasis in immunosuppressed patients, particularly those infected with human T-lymphotropic virus type 1/2, is infrequent. We describe the case of a Peruvian farmer from the central jungle with human T-lymphotropic virus type 1/2 infection, with 2 months of illness characterized by respiratory and gastrointestinal symptoms associated with fever, weight loss, and enlarged lymph nodes. Strongyloides stercoralis and Paracoccidioides brasiliensis were isolated in sputum and bronchoalveolar lavage samples, respectively. The clinical evolution was favorable after the patient received ivermectin and amphotericin B. We hypothesize that autoinfestation by S. stercoralis in human T-lymphotropic virus type 1/2-infected patients may contribute to the disseminated presentation of Paracoccidioides spp. Understanding epidemiological context is crucial for suspecting opportunistic regional infections, particularly those that may coexist in immunosuppressed patients.

    HTLV-1是感染CD4+T细胞的逆转录病毒。大多数患有HTLV-1感染的人仍然无症状,但有些人可能会发展为HTLV-1相关的脊髓病/热带痉挛性轻瘫(HAM/TSP)或成人T细胞白血病/淋巴瘤。HAM/TSP的特征是进行性痉挛和下肢无力,以及失去膀胱控制和感觉障碍。发生HAM/TSP的风险与感染持续时间和前病毒负荷有关。目前尚无治愈该疾病的方法,但药物可以帮助控制症状并减缓疾病的进展。这是一名66岁的女性,她在康涅狄格州的一家医院表现出虚弱和痉挛的非特异性症状,随后被诊断为HAM/TSP。患者的诊断强调了在全球化世界中考虑以前仅限于特定流行地区的疾病的重要性,在全球化世界中,移民和人口混合可能会增加。此类病例的早期识别和管理对于优化患者预后和生活质量至关重要。
    HTLV-1 is a retrovirus virus that infects CD4+ T cells. Most people with HTLV-1 infection remain asymptomatic but some may develop conditions such as HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) or adult T-cell leukemia/lymphoma. HAM/TSP is characterized by progressive spasticity and weakness of the lower extremities, as well as loss of bladder control and sensory disturbances. The risk of developing HAM/TSP is associated with the duration of infection and the proviral load. There is currently no cure for the disease but medications can help manage symptoms and slow the progression of the disease. This is the case of a 66-year-old female who presented with nonspecific symptoms of weakness and spasticity in a hospital in Connecticut and was subsequently diagnosed with HAM/TSP. The patient\'s diagnosis highlights the importance of considering diseases previously confined to specific endemic regions in a globalized world where increased emigration and population mixing can occur. Early identification and management of such cases is essential for optimizing patient outcomes and quality of life.

  • 人类T细胞淋巴病毒1型(HTLV-1)相关的细支气管肺泡疾病(HABA)是一种肺部疾病,其特征是HTLV-1携带者和成人T细胞白血病/淋巴瘤(ATLL)。我们在此报告了一名85岁的女性,该女性携带HTLV-1并伴有HABA,在高分辨率计算机断层扫描中,两肺中都出现了小结节,而在病理学上出现了淋巴细胞浸润并伴有非坏死性肉芽肿。这种罕见的HABA病例应与结节病区分开来,过敏性肺炎,或者粟粒性肺结核.
    Human T-cell lymphotropic virus type-1 (HTLV-1)-associated bronchioloalveolar disorder (HABA) is a pulmonary disorder characterized by lymphocytic infiltration of the peribronchiolar space and interstitium in HTLV-1 carriers and in adult T-cell leukemia/lymphoma (ATLL). We herein report an 85-year-old woman carrying HTLV-1 with HABA who presented with a miliary pattern of micronodules in both lungs on high-resolution computed tomography and a lymphocytic infiltrate with non-necrotizing granulomas on pathology. This rare case of HABA should be differentiated from sarcoidosis, hypersensitivity pneumonitis, or miliary tuberculosis.

    未经证实:人类1型T细胞淋巴病毒是一种逆转录病毒,可能导致严重的疾病,例如与HTLV-1(IDH)和成人T细胞白血病/淋巴瘤(ATL)相关的感染性皮炎。IDH是一种儿童慢性复发性感染湿疹,ATL是一种独特的外周T细胞白血病/淋巴瘤,它分为以下类型:阴燃,原发性皮肤肿瘤,慢性,淋巴瘤和急性。在IDH的过程中,IDH向ATL的进展先前已在3名年轻患者中报道,其中两人来自巴伊亚州(巴西)。我们介绍了一名22岁男子的病例,他从小就患有IDH,并在18个月前发展为ATL。淋巴瘤病变叠加在先前存在的IDH病变上(前额,腋窝,脐带区,和颈部)或通常受IDH(外生殖器,胃下,腹股沟,和眼睑)。ATL的皮肤病变非常常见,但是在这个病人身上,除了浸润的斑块和丘疹在组织学上与扩张的Pautrier脓肿相对应的皮肤上出现囊泡。囊泡ATL是一种罕见的疾病。这种情况构成了IDH和ATL之间密切相关的一个非常明显的例子。
    UNASSIGNED: The human T-cell lymphotropic virus type 1 is a retrovirus that may cause severe diseases such as infective dermatitis associated with HTLV-1 (IDH) and adult T-cell leukemia/lymphoma (ATL). IDH is a chronic relapsing infected eczema of childhood, and ATL is a distinct type of peripheral T-cell leukemia/lymphoma, which is classified into the following types: smoldering, primary cutaneous tumoral, chronic, lymphoma, and acute. Progression of IDH to ATL during the course of IDH has been previously reported in 3 young patients, two of them from Bahia (Brazil). We present the case of a 22-year-old man who had IDH since childhood and developed ATL 18 months ago. The lymphoma lesions were superimposed on previously existing IDH lesions (forehead, axillae, umbilical area, and neck) or in areas generally affected by IDH (external genitalia, hypogastrium, groin, and eyelid). Cutaneous lesions in ATL are very frequent, but in this patient, besides infiltrated plaques and papules presented vesicles on the skin corresponding histologically to dilated Pautrier abscesses. Vesicular ATL is a rare condition. This case constitutes a very demonstrative example of the close correlation between IDH and ATL.

    背景:恶性浸润占急性肝衰竭病例的0.5%,非霍奇金淋巴瘤是主要原因。成人T细胞淋巴瘤/白血病(ATLL)是急性肝炎的罕见来源,仅报告了3例病例,所有病例都立即恶化并死亡。ATLL从人类T淋巴细胞病毒1(HTLV-1)上升,常见于日本(南部和北部岛屿),加勒比海,中美洲和南美洲,热带非洲,罗马尼亚,伊朗北部。在密克罗尼西亚,本地出生的HTLV-1感染不存在或极为罕见。
    方法:一名77岁的马绍尔人出现在急诊科,有1周的全身无力史,疲劳,和恶心。体格检查显示宫颈丘疹样结节和巩膜黄疸。
    方法:对于230IU/L的天冬氨酸转氨酶(参考范围[RR]:0-40),丙氨酸转氨酶227IU/L(RR:0-41),133IU/L的碱性磷酸酶(RR:35-129),总胆红素为4.7mg/dL(RR:0-1.2),支持急性肝损伤。血小板计数为11.6x104/μL(RR:15.1-42.4×104),血红蛋白为13.8g/dL(RR:13.7-17.5),白细胞计数为7570/μL(RR:3800-10,800),中性粒细胞占81.8%(RR:34.0-72.0),淋巴细胞占10.4%(RR:12.0-44.0)。外周血涂片显示淋巴细胞异常,偶有花细胞形态。HTLV-1/2抗体检测呈阳性。皮肤和肝脏活检证实非典型T细胞浸润。确定了ATLL的诊断。
    方法:选择环磷酰胺姑息化疗的患者,长春新碱,和泼尼松(CVP)。他开始无限期地使用齐多夫定250mgbisindie(BID)进行抗病毒治疗。Ursodiol和胆甾胺用于治疗他的高胆红素血症。
    结果:入院四周,患者恢复到接近基线的功能状态并出院回家.
    结论:该病例突出表明,ATLL最初可以表现为孤立的急性肝炎,以及仔细的外周血涂片检查如何阐明肝炎的病因。我们还提供了使用熊儿二醇和胆甾胺治疗高胆红素血症的支持。此外,与以前关于ATLL表现为肝功能障碍的报道不同,在这种情况下,联合抗病毒和CVP化疗是有效的。最后,密克罗尼西亚地区很少有HTLV-1感染的人口统计报告,我们的病例代表了马绍尔患者中出现急性肝衰竭的首例HTLV-1相关ATLL的索引病例。
    BACKGROUND: Malignant infiltration accounts for 0.5% of acute liver failure cases, with non-Hodgkin\'s lymphoma the predominant cause. Adult T-cell lymphoma/leukemia (ATLL) is a rarer source of acute hepatitis, with only 3 cases reported and all resulting in immediate deterioration with death. ATLL rises from human T-lymphocytic virus-1 (HTLV-1), commonly found in Japan (southern and northern islands), the Caribbean, Central and South America, intertropical Africa, Romania, and northern Iran. In Micronesia, HTLV-1 infection amongst native-born is absent or exceedingly rare.
    METHODS: A 77-year-old Marshallese man presented to the emergency department with a 1-week history of generalized weakness, fatigue, and nausea. The physical exam revealed a cervical papulonodular exanthem and scleral icterus.
    METHODS: Laboratory studies were remarkable for aspartate-aminotransferase of 230 IU/L (reference range [RR]: 0-40), alanine-aminotransferase of 227 IU/L (RR: 0-41), alkaline phosphatase of 133 IU/L (RR: 35-129), and total bilirubin of 4.7 mg/dL (RR: 0-1.2), supporting acute liver injury. Platelet count was 11.6x104/μL (RR: 15.1-42.4 × 104), hemoglobin was 13.8 g/dL (RR: 13.7-17.5), and white blood cell count was 7570/μL (RR: 3800-10,800) with 81.8% neutrophils (RR: 34.0-72.0) and 10.4% lymphocytes (RR: 12.0-44.0). The peripheral blood smear demonstrated abnormal lymphocytes with occasional flower cell morphology. HTLV-1/2 antibody tested positive. The skin and liver biopsies confirmed atypical T-cell infiltrate. The diagnosis of ATLL was established.
    METHODS: The patient elected for palliative chemotherapy with cyclophosphamide, vincristine, and prednisone (CVP). He began antiviral treatment with zidovudine 250 mg bis in die (BID) indefinitely. Ursodiol and cholestyramine were added for his hyperbilirubinemia.
    RESULTS: Four weeks from admission, the patient returned to near baseline functional status and was discharged home.
    CONCLUSIONS: This case highlights that ATLL can initially present as isolated acute hepatitis, and how careful examination of peripheral blood-smear may elucidate hepatitis etiology. We also present support for utilizing ursodiol with cholestyramine for treating a hyperbilirubinemia. Moreover, unlike prior reports of ATLL presenting as liver dysfunction, combined antiviral and CVP chemotherapy was effective in this case. Lastly, there are seldom demographic reports of HTLV-1 infection from the Micronesian area, and our case represents the first indexed case of HTLV-1-associated-ATLL presenting as acute liver failure in a Marshallese patient.

    背景:掌plant角化过度是一种皮肤表现,与人类T细胞淋巴细胞病毒感染没有明显联系,这是一种逆转录病毒,在大多数情况下不会发展为临床病理,其症状可能未被发现。皮肤是受影响最大的器官之一,然而直到现在只有脂溢性皮炎,与HTLV-1相关的干燥病/鱼鳞病和感染性皮炎已被描述为该疾病的皮肤临床表现。
    方法:我们介绍了一名36岁的男性患者,其血清学记录为HTLV-1感染,出现腹泻症状的人,由于类圆圆线虫的吸收不良,体格检查显示与皮肤活检证实的广泛性干燥和掌plant角化病有关。排除了其他感染性病因和恶性肿瘤。这种临床表现通过皮肤水化来管理,和皮肤护理,改善了增厚的皮肤,使其不那么明显。
    结论:根据我们的经验,这是首例报道的与人类淋巴细胞病毒感染相关的掌plant角化病。这是之前尚未与HTLV-I结合确认的皮肤表现。这意味着掌plant角化症是这种感染的新临床表现,在具有这些皮肤病学特征的流行地区的患者的初始方法中应考虑这一点。
    BACKGROUND: Palmoplantar hyperkeratosis is a cutaneous manifestation that had not been clearly associated with infection by the human T-cell lymphotropic virus, which is a retrovirus that in most cases does not develop clinical pathologies and its symptoms may be undetected. The skin is one of the most affected organs, however until now only seborrheic dermatitis, xerosis/ichthyosis and infective dermatitis associated with HTLV-1 have been described as cutaneous clinical manifestations of this disease.
    METHODS: We present the case of a 36-year-old male patient with serologically documented HTLV-1 infection, who presented symptoms of diarrhea, malabsorption due to Strongyloides stercoralis, and in whom a physical examination revealed an association with generalized xerosis and palmoplantar keratoderma confirmed by skin biopsy. Other infectious etiologies and malignancy were ruled out. This clinical manifestation was managed with dermal hydration, and skin care which improved the thickened skin and make it less noticeable.
    CONCLUSIONS: According to our experience, this is the first reported case of palmoplantar keratoderma associated with a human lymphotropic virus infection. This is a skin manifestation that has not been confirmed in conjunction with HTLV-I before. This implies that palmoplantar keratoderma is a new clinical manifestation of this infection, that should be considered in the initial approach of patients in endemic areas with these dermatological characteristics.

    人类嗜T淋巴细胞病毒I型(HTLV-I)是与成人T细胞淋巴瘤(ATL)和HTLV-I相关的脊髓病/热带痉挛性轻瘫(HAM/TSP)相关的逆转录病毒。除了HAM/TSP和ATL,已经报道了HTLV-I相关的脑病和小脑受累。我们报告了一例87岁的日本妇女,患有进行性构音障碍和步态障碍。神经系统检查显示单词查找困难,扫描语音,扫视眼球运动,视力障碍,凝视诱发的眼球震颤和双侧异常。没有运动无力或痉挛。在她的血清和脑脊液中均检测到HTLV-I抗体。脑脊液新蝶呤(57pg/mL)和IgG指数(3.27)显着升高。MRI显示小脑肿胀。她最终被诊断为HTLV-I相关的小脑炎。两个疗程的大剂量静脉注射甲基泼尼松治疗可减轻小脑共济失调和小脑肿胀。提示HTLV-I感染可导致小骨炎,无论是否存在ATL或HAM/TSP。
    Human T-lymphotropic virus type I (HTLV-I) is a retrovirus associated with adult T-cell lymphoma (ATL) and HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). In addition to HAM/TSP and ATL, HTLV-I-associated encephalopathy and cerebellar involvement have been reported. We report a case of an 87-year-old Japanese woman presenting with progressive dysarthria and gait disturbance. Neurological examination showed word-finding difficulty, scanning speech, saccadic eye movements, ocular dysmetria, gaze-evoked nystagmus and bilateral dysmetria. There was no motor weakness or spasticity. HTLV-I antibody was detected in both her serum and cerebrospinal fluid. Cerebrospinal fluid neopterin (57 pg/mL) and IgG index (3.27) were significantly elevated. MRI showed cerebellar swelling. She was finally diagnosed with HTLV-I associated cerebellitis. Two courses of high-dose intravenous methylpredonine therapy attenuated cerebellar ataxia and cerebellar swelling. It suggests that cerebellitis can result from HTLV-I infection, regardless of the existence of ATL or HAM/TSP.

    The human T cell lymphotropic virus type 1 (HTLV-1) is the first human retrovirus discovered. Since then, it has spread worldwide and is mainly associated with adult T cell leukemia/lymphoma (ATLL) and HTLV1-associated myelopathy (HAM). Its relationship, however, with other types of cancer is controversial. We describe the case of a patient presenting with small cells lung epidermoid carcinoma who had recently developed HAM, and a review of the literature related to these conditions. This is the first case of this type of lung cancer, the same of the first description in the literature, associated with HAM outside Japan.

    Human T-cell leukemia virus type 2 (HTLV-2) is non-endemic in Japan unlike the related HTLV type 1. Previously, although HTLV-2-seropositivity was identified via western blotting in one male blood donor in Japan, there have been no reports of HTLV-2 provirus detection by nucleic acid testing. In this report, one Japanese pregnant woman was clinically diagnosed as being HTLV-2-infected with a line immunoassay for specific antibodies after primary testing through prenatal screening in Japan. In genomic DNA of her peripheral blood mononuclear cells, HTLV-2 proviral genome was detected by nucleic acid testing (three methods) with quantitative polymerase chain reaction. The full-genome sequence of this strain was successfully determined. The identified virus was interestingly characterized as a presumed progenitor of subtypes a and c by recombination region and phylogenetic tree analyses. In conclusion, the present infection is, to our knowledge, the first case of molecularly identified and genetically characterized HTLV-2 infection found via prenatal screening in non-endemic Japan.
