  • 文章类型: Review
    塔拉真菌病是由马尔尼菲塔拉真菌病引起的一种严重的机会性传染病,主要发生在免疫功能低下的患者。该病主要流行于东南亚和南亚的热带国家和地区,但非流行地区也有塔拉真菌病患者。本病无特征性临床表现,诊断困难。延迟诊断通常会导致死亡。
    两名患者均有细胞免疫缺陷。病例1有获得性免疫缺陷综合征病史,病例2有肾移植史和葡萄糖-6-磷酸脱氢酶缺乏症。他们都发烧了,贫血,疲劳,和皮肤损伤。病例1有消化道出血,淋巴结肿大,和肝脾肿大.病例2有咳嗽和呼吸困难。两名患者均有血小板减少症和低白蛋白血症;中性粒细胞比率增加,降钙素原,和C反应蛋白;肝功能异常和凝血功能障碍。病例1痰培养,血培养,支气管肺泡灌洗液为马尔尼菲氏杆菌阳性。在病例2的血液培养中检测到马尔尼菲T.Marneffei,并感染了近叶念珠菌和肺孢子虫。胸部CT扫描主要表现为肺渗出性病变。尽管这两名患者得到了积极的治疗,他们死于疗效不佳。
    塔拉真菌病发病隐匿,漫长的课程,不典型的临床症状,成像性能和实验室结果,诊断困难,和高死亡率。因此,重要的是要及时考虑和治疗感染后免疫功能低下患者的塔拉真菌病,以降低死亡率。
    UNASSIGNED: Talaromycosis is a serious opportunistic infectious disease caused by Talaromyces marneffei, which mostly occurs in immunocompromised patients. The disease is mainly prevalent in tropical countries and regions of Southeast Asia and South Asia, but non-endemic areas also have patients with Talaromycosis. The disease has no characteristic clinical manifestations and is difficult to diagnose. Delayed diagnosis often leads to death.
    UNASSIGNED: Both patients had cellular immunodeficiency. Case 1 had a history of acquired immune deficiency syndrome, and case 2 had a history of renal transplantation and glucose-6-phosphate dehydrogenase deficiency. They all had fever, anemia, fatigue, and skin lesions. Case 1 had gastrointestinal bleeding, enlarged lymph nodes, and hepatosplenomegaly. Case 2 had cough and dyspnea. Both patients had thrombocytopenia and hypoalbuminemia; an increased neutrophil ratio, procalcitonin, and C-reactive protein; and abnormal liver function and coagulation dysfunction. Case 1 sputum culture, blood culture, and bronchoalveolar lavage fluid were positive for T. marneffei. T. marneffei was detected in the blood culture of case 2, with infection of Candida parapsilosis and Pneumocystis jirovecii. Chest computed tomography scan mainly showed pulmonary exudative lesions. Although these two patients were actively treated, they died of poor efficacy.
    UNASSIGNED: Talaromycosis has an insidious onset, long course, atypical clinical symptoms, imaging performance and laboratory results, difficult diagnosis, and high mortality. Therefore, it is important to promptly consider and treat Talaromycosis in immunocompromised patients upon infection in order to reduce mortality.

    HIV患者的软疣样皮肤病变可能是各种疾病的表现特征。因此,实验室调查在做出准确的病因诊断中起着至关重要的作用。讨论HIV患者软体动物样病变中通常进行的实验室测试结果的研究非常稀疏。因此,我们进行了一项研究来弥合这一文献空白。这项研究是在四名患有软体动物样皮肤病变的HIV患者中进行的。对所有患者进行shave活检,并将标本送去氢氧化钾(KOH)安装/克染色,真菌培养和组织病理学检查。来自病例1、2、3和4的组织样本被称为样本A,B,C和D,分别。KOH安装在样品A和B中显示出大小约6μm的酵母样圆形体。样品C和D中的KOH安装显示出分隔的分支菌丝。样品C中的KOH安装也显示出大约35μm的大圆形体,其被鉴定为软体动物体。样品A和B的组织病理学显示出提示真菌病的特征,而样品C和D的组织病理学显示出传染性软体动物的特征。Sabouraud葡萄糖琼脂中的培养在样品A中生长了马内菲B和C。通常可用的实验室测试极大地帮助建立软体动物样皮肤病变的诊断。然而,需要清楚地理解实验室测试中的某些细微差别。需要进行更大样本量的研究,以确定痘病毒和马尔尼菲T.如样品C所示。
    Molluscum-like skin lesions in HIV patients can be the presenting feature of the vast array of diseases. Hence, laboratory investigations play a crucial role in making an accurate etiological diagnosis. The studies that discuss the outcomes of commonly performed laboratory tests in molluscum-like lesions in HIV patients are very sparse. Hence, we conducted a study to bridge this literature gap. This study was conducted among four patients with HIV who had molluscum-like skin lesions. Shave biopsy was performed on all the patients and the specimens were sent for potassium hydroxide (KOH) mount/gram stain, fungal culture and histopathological examination. The tissue samples from cases 1, 2, 3 and 4 are mentioned as samples A, B, C and D, respectively. KOH mount showed yeast-like rounded bodies around 6 μm in size in samples A and B. The KOH mount in samples C and D showed septate branching hyphae. KOH mount in sample C also showed large rounded bodies around 35 μm which were identified as molluscum bodies. The histopathology of samples A and B showed features suggestive of talaromycosis whereas the histopathology of samples C and D showed features of molluscum contagiosum. Culture in Sabouraud Dextrose Agar grew T. marneffei in samples A, B and C. The commonly available laboratory tests immensely help in establishing the diagnosis of molluscum-like skin lesions. However, certain nuances in laboratory tests need to be understood lucidly. Studies with larger sample sizes need to be conducted to determine the possible co-infection of poxvirus and T. marneffei, as witnessed in sample C.

    马尔尼菲塔拉酵母是一种热双态真菌,会影响多个器官并经常侵入免疫功能低下的个体。然而,只有少数研究报告了与马尔尼菲有关的肠道感染的存在。在这里,我们报道了一例男性肠道马尔尼菲感染病例,他有1个月的间歇性发热病史,腹痛,和腹泻。人类免疫缺陷病毒抗体检测结果为阳性。肠道活检组织的周期性酸性希夫和蛾摩拉甲胺银染显示马尔尼菲感染。幸运的是,及时抗真菌治疗后,患者症状迅速缓解。此外,我们总结并描述了临床特征,管理,以及肠道马尔尼菲梭菌感染患者的预后。共确定了29名患者,其中大多数(65.52%)患有获得性免疫缺陷综合征。主要临床特征包括贫血,发烧,腹痛,腹泻,减肥,和淋巴结病。横结肠和降结肠,回盲肠,和升结肠是最常见的病变部位。相当一部分患者(31.03%)出现肠梗阻,肠穿孔,和消化道出血.在29名患者中,六人接受了手术,23例抗真菌治疗成功存活,5人死于马尔尼菲感染,其中一人死于不明原因.当流行地区的免疫缺陷患者出现非特异性症状时,应考虑马尔尼菲肠道感染。比如发烧,腹痛,和腹泻。适当和及时的内窥镜检查避免了诊断的延误。早期积极抗真菌治疗可改善患者的临床预后。
    Talaromyces marneffei is a thermally dimorphic fungus that affects multiple organs and frequently invades immunocompromised individuals. However, only a few studies have reported the presence of intestinal infection associated with T. marneffei. Herein, we reported a case of intestinal T. marneffei infection in a man who complained of a 1-month history of intermittent fever, abdominal pain, and diarrhea. The result of the human immunodeficiency virus antibody test was positive. Periodic acid-Schiff and Gomorrah\'s methylamine silver staining of the intestinal biopsy tissue revealed T. marneffei infection. Fortunately, the patient\'s symptoms rapidly resolved with prompt antifungal treatment. In addition, we summarized and described the clinical characteristics, management, and outcomes of patients with intestinal T. marneffei infection. A total of 29 patients were identified, the majority of whom (65.52%) were comorbid with acquired immunodeficiency syndrome. The main clinical features included anemia, fever, abdominal pain, diarrhea, weight loss, and lymphadenopathy. The transverse and descending colon, ileocecum, and ascending colon were the most common sites of lesions. A considerable number of patients (31.03%) developed intestinal obstruction, intestinal perforation, and gastrointestinal bleeding. Of the 29 patients, six underwent surgery, 23 survived successfully with antifungal treatment, five died of T. marneffei infection, and one died of unknown causes. T. marneffei intestinal infection should be considered when immunodeficient patients in endemic areas present with non-specific symptoms, such as fever, abdominal pain, and diarrhea. Appropriate and timely endoscopy avoids delays in diagnosis. Early aggressive antifungal therapy improves the clinical outcomes of patients.

    Talaromycosis is a fatal opportunistic infection prevalent in human immunodeficiency virus (HIV)-infected patients, previous studies suggest environmental humidity is associated with monthly talaromycosis hospitalizations of HIV-infected patients, but the acute risk factor remains uncertain. In this study, we evaluated the associations between talaromycosis hospitalizations of HIV-infected patients (n = 919) and environmental factors including meteorological variables and air pollutants at the event day (assumed \"lag 0\" since the exact infection date is hard to ascertain) and 1-7 days prior to event day (lag 1-lag 7) in conditional logistics regression models based on a case crossover design. We found that an interquartile range (IQR) increase in temperature at lag 0-lag 7 (odds ratio [OR] [95% CI] ranged from 1.748 [1.345-2.273] to 2.184 [1.672-2.854]), and an IQR increase in humidity at lag 0 (OR [95% CI] = 1.192 [1.052-1.350]), and lag 1 (OR [95% CI] = 1.199 [1.056-1.361]) were significantly associated with talaromycosis hospitalizations of HIV-infected patients. Besides, temperature was also a common predictor for talaromycosis in patients with co-infections including candidiasis (n = 386), Pneumocystis pneumonia (n = 183), pulmonary tuberculosis (n = 141), and chronic hepatitis (n = 158), while humidity was a specific risk factor for talaromycosis in patients with candidiasis, and an air pollutant, SO2, was a specific risk factor for talaromycosis in patients with Pneumocystis pneumonia. In an age stratified evaluation (cutoff = 50 years old), temperature was the only variable positively associated with talaromycosis in both younger and older patients. These findings broaden our understanding of the epidemiology and pathogenesis of talaromycosis in HIV-infected patients.

    BACKGROUND: Talaromyces marneffei (TM) primarily infects patients with co-morbidities that cause immunodeficiency, but non-secretory myeloma (NSMM) is rare. TSM and NSMM are associated with fever, osteolysis, and swollen lymph nodes, thereby making it difficult for clinicians to make differential diagnosis. In this case, we describe TM infection coexisting with NSMM.
    METHODS: We retrospectively reviewed the case of a male (without human immunodeficiency virus infection) with fever, thoracalgia, swollen lymph nodes, and subcutaneous nodules who presented to the First Affiliated Hospital of Guangxi Medical University in February 2014. Chest computed tomography revealed patchy infiltration and positron emission tomography/computed tomography showed increased metabolic activity in the lower-right lung, lymph nodes, left ninth rib, and right ilium. Pathological examination of the lung, lymph nodes, subcutaneous nodules, and bone marrow showed no malignancy, he was diagnosed with community-acquired pneumonia. His clinical symptoms did not improve after anti-bacterial, anti-Mycobacterium tuberculosis, and anti-non-M. tuberculosis treatment. Later, etiological culture and pathological examination of the subcutaneous nodule proved TM infection, and the patient was re-diagnosed with disseminated TSM, which involved the lungs, lymph nodes, skin, bone, and subcutaneous tissue. After antifungal treatment, the patient showed significant improvement, except for the pain in his bones. Imaging showed aggravated osteolysis, and bone marrow biopsy and immunohistochemistry indicated NSMM. Thus, we conclusively diagnosed the case as NSMM with TSM (involving the lungs, lymph nodes, skin, and subcutaneous tissue). His condition improved after chemotherapy, and he was symptom-free for 7 years.
    CONCLUSIONS: TM infection is rare in individual with NSMM. Since they have clinical manifestation in common, easily causing misdiagnosis and missed diagnosis, multiple pathological examinations and tissue cultures are essential to provide a differential diagnosis.

    Concurrence of talaromycosis, an infection caused by the opportunistic fungal pathogen Talaromyces marneffei and Kaposi sarcoma, a common vascular tumor, is a rare but severe medical condition in patients infected with the human immunodeficiency virus (HIV). Despite poor outcomes, the clinical characteristics and management strategies for HIV-infected patients with comorbid Kaposi sarcoma and talaromycosis have not been well documented.
    A 33-year-old HIV-positive male patient presented to the Department of Infectious Diseases at Wenzhou Central Hospital with cough, sputum expectoration, hemoptysis, rashes on the feet and violaceous plaques in the oral cavity. Chest computed tomography (CT) showed bilateral nodules, patchy shadows and lymphadenectasis. Skin biopsy and histopathological examination indicated Kaposi sarcoma. T. marneffei was isolated from blood cultures and suggested talaromycosis. The patient\'s overall conditions significantly improved following initiation of combination antiretroviral therapy (cART) and chemotherapy for Kaposi sarcoma and antifungal treatment for talaromycosis.
    Severe medical conditions such as Kaposi sarcoma and talaromycosis may coexist in HIV-infected patients and pose an increased risk of mortality. Etiological diagnosis and treatment are the keys to the successful management of HIV-infected patients with these concurrent conditions.

    Emergent fungal infections are rare conditions that frequently cause death. Talaromycosis is a fungal infection caused by Talaromyces sp. that is predominantly prevalent in patients with acquired immunodeficiency syndrome caused by human immunodeficiency virus infection, but in recent years we have noticed increasing reports of cases in people with other underlying conditions. We report a case of talaromycosis in a Stage IV non-small cell lung cancer female patient undergoing whole brain radiation therapy who presented to us with increasing dyspnea, cough and fever. The diagnosis was based on sputum and blood cultures, and even though our patient received anti-fungal treatment, the outcome was fatal. This case shows that a high index of suspicion could be essential for such a highly lethal but potentially treatable fungal infection.

    塔拉真菌病是由马尔尼菲塔拉酵母引起的一种罕见的深部真菌感染。目前,甲基苯丙胺已成为仅次于大麻的世界第二大药物滥用类别,并已成为严重的公共卫生问题。甲基苯丙胺可以抑制人体免疫系统,增加病原微生物感染的概率。2016年10月8日,一名20岁有2个月发热史的男子入院。住院期间出现血便和腹痛。体检无明显异常。因为误诊,他接受了不当的治疗。周期性酸性希夫染色(PAS)染色显示回肠远端黏膜,升结肠,横结肠,乙状结肠被大量的组织细胞浸润,其中含有大量的蓝紫色颗粒。此外,回肠粘膜固有层可见大量组织细胞和多核巨细胞,在组织细胞中可以看到真菌孢子。最后,他被诊断为塔拉真菌病,每天服用伊曲康唑0.2g。5天后,温度下降到正常,炎症消失了,他继续服用伊曲康唑6个月。由于对吸毒史的忽视和隐瞒,与药物相关的talar真菌病经常被误诊。诊断足真菌病需要病理检查。这种情况需要长期的抗真菌治疗。
    Talaromycosis is a rare deep fungal infection caused by Talaromyces marneffei. Currently, methamphetamine has become the second-largest drug abuse category in the world after cannabis and has become a serious public health problem. Methamphetamine can inhibit human immune system and increase the probability of pathogenic microorganism infection. On 8 October 2016, a 20-year-old man with a fever history of 2 months was admitted to our hospital. He had bloody stools and abdominal pain during hospitalization. There was no significant abnormality in physical examination. Because of the misdiagnosis, he underwent improper treatment. Periodic acid-Schiff stain (PAS) staining showed that the mucosa of distal ileum, ascending colon, transverse colon, and sigmoid colon were infiltrated by a large number of tissue cells, which contained a large number of blue purple particles. In addition, a large number of histiocytes and multinucleated giant cells can be seen in the lamina propria of ileum mucosa, and fungal spores can be seen in histiocytes. Finally, he was diagnosed as talaromycosis and took itraconazole 0.2 g twice a day. After 5 days, the temperature dropped to normal and the inflammation disappeared, and he continued to take itraconazole for 6 months. Due to the neglect of the history of drug abuse and the concealment, drug-related talaromycosis is often misdiagnosed. Pathological examination is warranted for diagnosis talaromycosis. This condition requires a long-term anti-fungal therapy.

    BACKGROUND: The incidence of Taralomyces marneffei infection in HIV-infected individuals has been decreasing, whereas its rate is rising among non-HIV immunodeficient persons, particularly patients with anti-interferon-gamma autoantibodies. T. marneffei usually causes invasive and disseminated infections, including fungemia. T. marneffei oro-pharyngo-laryngitis is an unusual manifestation of talaromycosis.
    METHODS: A 52-year-old Thai woman had been diagnosed anti-IFNɣ autoantibodies for 4 years. She had a sore throat, odynophagia, and hoarseness for 3 weeks. She also had febrile symptoms and lost 5 kg in weight. Physical examination revealed marked swelling and hyperemia of both sides of the tonsils, the uvula and palatal arches including a swelling of the epiglottis, and arytenoid. The right tonsillar biopsy exhibited a few intracellular oval and elongated yeast-like organisms with some central transverse septum seen, which subsequently grew a few colonies of T. marneffei on fungal cultures. The patient received amphotericin B deoxycholate 45 mg/dayfor 1 weeks, followed by oral itraconazole 400 mg/day for several months. Her symptoms completely resolved without complication.
    CONCLUSIONS: In patients with anti-IFN-ɣ autoantibodies, T. marneffei can rarely cause a local infection involving oropharynx and larynx. Fungal culture and pathological examination are warranted for diagnosis T. marneffei oro-pharyngo-laryngitis. This condition requires a long term antifungal therapy.
