  • 文章类型: Systematic Review
    世界卫生组织,为了应对日益增长的真菌疾病负担,建立了制定真菌病原体优先级列表的过程。本系统评价旨在评估马尔尼菲塔拉菌感染的流行病学和影响。球虫物种,和副球菌物种。搜索PubMed和WebofSciences数据库,以确定2011年1月1日至2021年2月23日期间发表的报告死亡率的研究。并发症和后遗症,抗真菌药敏,可预防性,年发病率,和趋势。总的来说,包括25、17和6篇文章,球虫属。和副球菌属。,分别。侵袭性距真菌病和副角菌病的死亡率很高(高达21%和22.7%,分别)。球孢子菌病患者住院频繁(高达84%),虽然持续时间短(平均/中位数3-7天),再入院很常见(38%)。观察到马尔尼菲和球藻对氟康唑和棘白菌素的敏感性降低。,而>88%的马尔尼菲分离株对伊曲康唑的最小抑制浓度值≤0.015μg/ml,泊沙康唑,和伏立康唑.塔拉真菌病患者死亡的危险因素包括CD4计数低(当CD4计数<200个细胞/μ1时,比值比为2.90,而当CD4计数<50个细胞/μ1时,比值比为24.26)。球孢子菌病和副球孢子菌病的爆发与建筑工作有关(相对风险增加4.4-210.6和5.7倍,分别)。在美利坚合众国,2014年至2017年期间球孢子菌病病例有所增加(从8232例至14364例/年).国家和全球监测以及更详细的研究,以更好地定义后遗症,危险因素,结果,全球分销,趋势是必需的。
    The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal pathogen priority list. This systematic review aimed to evaluate the epidemiology and impact of infections caused by Talaromyces marneffei, Coccidioides species, and Paracoccidioides species. PubMed and Web of Sciences databases were searched to identify studies published between 1 January 2011 and 23 February 2021 reporting on mortality, complications and sequelae, antifungal susceptibility, preventability, annual incidence, and trends. Overall, 25, 17, and 6 articles were included for T. marneffei, Coccidioides spp. and Paracoccidioides spp., respectively. Mortality rates were high in those with invasive talaromycosis and paracoccidioidomycosis (up to 21% and 22.7%, respectively). Hospitalization was frequent in those with coccidioidomycosis (up to 84%), and while the duration was short (mean/median 3-7 days), readmission was common (38%). Reduced susceptibility to fluconazole and echinocandins was observed for T. marneffei and Coccidioides spp., whereas >88% of T. marneffei isolates had minimum inhibitory concentration values ≤0.015 μg/ml for itraconazole, posaconazole, and voriconazole. Risk factors for mortality in those with talaromycosis included low CD4 counts (odds ratio 2.90 when CD4 count <200 cells/μl compared with 24.26 when CD4 count <50 cells/μl). Outbreaks of coccidioidomycosis and paracoccidioidomycosis were associated with construction work (relative risk 4.4-210.6 and 5.7-times increase, respectively). In the United States of America, cases of coccidioidomycosis increased between 2014 and 2017 (from 8232 to 14 364/year). National and global surveillance as well as more detailed studies to better define sequelae, risk factors, outcomes, global distribution, and trends are required.

    背景:副孢子菌病是一种被忽视的热带病,由副孢子菌属真菌引起。广泛的症状与疾病有关;然而,肺和皮肤是主要受影响的部位。这种疾病主要见于生活在拉丁美洲农村地区的人们。
    方法:我们介绍了一例对抗真菌治疗反应缓慢的严重播散性副病菌的儿科病例。三个月内,症状演变成肝脾肿大,坏死的颈部和腹部淋巴结,和脾脓肿。两性霉素B脱氧胆酸盐和伊曲康唑的临床反应缓慢,导致胸膜和腹膜腔积液,心力衰竭和休克。两性霉素B脱氧胆酸被脂质体制剂取代,没有回应。随后,治疗中加入了泼尼松,这导致了临床反应的改善。血清学副球菌抗体滴度不典型,在关键阶段滴度非常低,在恢复期显着增加。最终用两性霉素B脱氧胆酸盐清除了感染,脂质体两性霉素B和皮质类固醇的使用。副孢子菌病血清学在出院后两年无反应性。
    结论:由于副球菌细胞引发的强烈炎症反应,短时间给予小剂量泼尼松可调节炎症反应并支持抗真菌治疗.
    BACKGROUND: Paracoccidioidomycosis is a neglected tropical disease caused by fungi of the genus Paracoccidioides. A wide range of symptoms is related to the disease; however, lungs and skin are the sites predominantly affected. The disease is mostly seen in people living in rural areas in Latin America.
    METHODS: We present a pediatric case of severe disseminated paracoccidioidomycosis that slowly responded to the antifungal treatment. Within three months, symptoms evolved into hepatosplenomegaly, necrotic cervical and abdominal lymph nodes, and splenic abscess. Clinical response to amphotericin B deoxycholate and itraconazole was slow, resulting in pleural and peritoneal cavity effusions, heart failure and shock. Amphotericin B deoxycholate was replaced by the liposomal formulation, with no response. Subsequently, prednisone was added to the treatment, which led to improvement in the clinical response. Serological Paracoccidioides antibody titers were atypical, with very low titers in the critical phase and significant increase during the convalescence phase. The infection was finally cleared up with amphotericin B deoxycholate, liposomal amphotericin B and the use of corticosteroids. Paracoccidioidomycosis serology was non-reactive two years post-discharge.
    CONCLUSIONS: Due to the intense inflammatory response triggered by Paracoccidioides cells, giving low-dose prednisone for a short period of time modulated the inflammatory response and supported antifungal treatment.

    在由两部分组成的继续医学教育系列的第一部分中,流行病学,临床特征,和真菌皮肤被忽视热带病(NTDs)的诊断方法,其中包括Eumycetoma,成色真菌病,副角菌病,孢子丝菌病,真菌病,塔拉真菌病,和大孢子菌病,被审查。这些感染,其中一些被世界卫生组织(世卫组织)正式指定为NTD,在全球范围内引起大量发病率和污名,并且由于与气候变化相关的地理扩展的潜力而受到越来越多的关注。在全球旅行和免疫抑制的背景下,国内发病率可能会增加。美国皮肤科医生可能在早期发现和开始适当治疗方面发挥核心作用,导致发病率和死亡率下降。
    In this part 1 of a 2-part continuing medical education series, the epidemiology, clinical features, and diagnostic methods for fungal skin neglected tropical diseases (NTDs), which include eumycetoma, chromoblastomycosis, paracoccidioidomycosis, sporotrichosis, emergomycosis, talaromycosis, and lobomycosis, are reviewed. These infections, several of which are officially designated as NTDs by the World Health Organization (WHO), cause substantial morbidity and stigma worldwide and are receiving increased attention due to the potential for climate change-related geographic expansion. Domestic incidence may be increasing in the setting of global travel and immunosuppression. United States dermatologists may play a central role in early detection and initiation of appropriate treatment, leading to decreased morbidity and mortality.

    在由两部分组成的继续医学教育系列的第二部分中,管理层,结果,和真菌皮肤被忽视的热带病(NTDs)的发病率,包括Eumycetoma,成色真菌病,副角菌病,孢子丝菌病,真菌病,塔拉真菌病,对叶真菌病进行了综述。虽然在资源有限的环境中,真菌皮肤NTD与贫困有关,在美国,它们更经常与免疫抑制和全球移民有关。这些感染有很高的发病率负担,包括毁容,身体残疾,共感染,恶性转化,心理健康问题,和财务影响。对于大多数真菌皮肤NTDs,管理困难,治愈率低。皮肤科医生在疾病早期启动适当治疗以改善患者预后方面发挥着核心作用。
    In this part 2 of a 2-part continuing medical education series, the management, outcomes, and morbidities for fungal skin neglected tropical diseases (NTDs), including eumycetoma, chromoblastomycosis, paracoccidioidomycosis, sporotrichosis, emergomycosis, talaromycosis, and lobomycosis are reviewed. While fungal skin NTDs are associated with poverty in resource-limited settings, they are more often associated with immunosuppression and global migration in the United States. These infections have a high morbidity burden, including disfigurement, physical disability, coinfection, malignant transformation, mental health issues, and financial impact. For most fungal skin NTDs, management is difficult and associated with low cure rates. Dermatologists play a central role in initiating appropriate treatment early in disease course in order to improve patient outcomes.

    我们报告了一名48岁的先前健康的女性的轻度单发慢性肺副球孢子菌病的本土病例,在地方性农村地区没有可能的环境暴露史,据推测是由于使用甲氨蝶呤控制基孔肯雅关节病继发的潜在肺灶重新激活所致。实验室检查排除了其他免疫抑制。她唯一的症状是干咳和胸痛。经穿刺肺活检确诊。体格检查没有异常,也没有中枢神经系统受累的证据。全腹部MRI显示其他器官未受累。计算机断层扫描显示,在使用伊曲康唑(200mg/天)的情况下,进展良好。在治疗前后进行时,会突出显示不同的断层摄影表现。结论:即使在没有持续环境暴露史和非地方性地理区域的女性中,也应考虑PCM。
    We report an autochthonous case of mild unifocal chronic pulmonary paracoccidioidomycosis in a 48-year-old previously healthy woman with no history of possible environmental exposures in endemic rural areas, supposedly resulting from reactivation of a latent pulmonary focus secondary to the use of methotrexate for the control of Chikungunya arthropathy. Laboratory investigation ruled out other immunosuppression. Her only symptoms were a dry cough and chest pain. Diagnosis confirmed by needle lung biopsy. There were no abnormalities on physical examination nor evidence of central nervous system involvement. MRI of the total abdomen showed no involvement of other organs. Computed chest tomography showed a favorable evolution under the use of itraconazole (200 mg/day). Different tomographic presentations findings are highlighted when performed before and after treatment. CONCLUSIONS: PCM should be considered even in a woman without a history of consistent environmental exposure and in a non-endemic geographic area.

    背景:准确的诊断对改善患者预后至关重要。通过双免疫扩散(DID)检测副球菌抗体是一种方便的诊断工具,但测试性能可能因某些因素而异。
    方法:我们使用商业制备的Paracoccidioides试剂(IMMY,美国),涉及40份血清标本,其中20例来自经证实的副宫颈真菌病患者和20例非该病患者。DID测试显示90%的灵敏度(95%CI=68%-99%)和100%的特异性(95%CI=83%-100%)。
    结论:我们的发现表明,使用商业试剂的DID可能为抗副孢子虫抗体检测提供了一种具有令人满意的测试性能的可行工具。
    BACKGROUND: Accurate diagnosis of paracoccidioidomycosis is crucial for improving patient outcomes. Paracoccidioides antibody detection by double immunodiffusion (DID) is a convenient diagnostic tool, but testing performance can vary based on certain factors.
    METHODS: We assessed DID performance using a commercially prepared Paracoccidioides reagents (IMMY, USA), involving 40 serum specimens, including 20 from patients with proven paracoccidioidomycosis and 20 from patients without the disease. The DID test demonstrated a sensitivity of 90% (95% CI=68%-99%) and a specificity of 100% (95% CI=83%-100%).
    CONCLUSIONS: Our findings suggest that DID using commercial reagents may provide a feasible tool with satisfactory testing performance for anti-Paracoccidioides antibody detection.

    血细胞计数对于评估感染期间骨髓细胞的产生和分化至关重要,测量疾病的严重程度,并监测治疗反应。慢性形式的副角菌病(PCM)的血细胞计数特征尚未得到充分探索。为了更好地了解PCM慢性形式的不同阶段的血液细胞的变化,我们评估了血细胞计数,包括自动化设备中未成熟的血细胞,对62例慢性PCM患者进行治疗前和治疗期间的随访。主要为男性(96.8%),平均年龄为54.3(标准差为6.9)岁,参与者表现出治疗前的状况,如贫血(45.2%),单核细胞增多症(38.7%),和白细胞增多(17.7%),临床治愈后变得不那么频繁。贫血在严重病例中更为普遍。值得注意的是,血红蛋白和网织红细胞血红蛋白含量增加,而白细胞,单核细胞,中性粒细胞,未成熟粒细胞,血小板减少。慢性PCM引起可管理的血液学异常,主要是红血丝系列。单核细胞增多症,指示单核细胞在PCM的免疫反应中的作用,是频繁的。后处理,尤其是在达到临床治愈后,在各种血液学指标中观察到显着改善,包括未成熟粒细胞和网织红细胞血红蛋白含量,强调感染对这些参数的影响。
    Blood count is crucial for assessing bone marrow\'s cell production and differentiation during infections, gaging disease severity, and monitoring therapeutic responses. The profile of blood count in chronic forms of paracoccidioidomycosis (PCM) has been insufficiently explored. To better understand the changes in hematological cells in different stages of the PCM chronic form, we evaluated the blood count, including immature blood cells in automated equipment, before and during the treatment follow-up of 62 chronic PCM patients. Predominantly male (96.8%) with an average age of 54.3 (standard deviation SD 6.9) years, participants exhibited pre-treatment conditions such as anemia (45.2%), monocytosis (38.7%), and leukocytosis (17.7%), which became less frequent after clinical cure. Anemia was more prevalent in severe cases. Notably, hemoglobin and reticulocyte hemoglobin content increased, while leukocytes, monocytes, neutrophils, immature granulocytes, and platelets decreased. Chronic PCM induced manageable hematological abnormalities, mainly in the red blood series. Monocytosis, indicating monocytes\' role in PCM\'s immune response, was frequent. Post-treatment, especially after achieving clinical cure, significant improvements were observed in various hematological indices, including immature granulocytes and reticulocyte hemoglobin content, underscoring the impact of infection on these parameters.
