  • 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,建立了制定真菌优先病原体名单的过程。本系统综述旨在评估eumycetoma的流行病学和影响。搜索了PubMed和WebofScience,以确定2011年1月1日至2021年2月19日之间发表的研究。报告死亡率的研究,住院护理,并发症和后遗症,抗真菌药敏,危险因素,可预防性,年发病率,全球分销,选择研究时间范围内的出现率。总的来说,14项研究符合纳入条件。发病率频繁,中度至重度生活质量损害占60.3%,截肢率高达38.5%,31.8%-73.5%的患者复发或长期疾病。潜在危险因素包括男性(56.6%-79.6%)。年龄较小(11-30岁;64%),和农业职业(62.1%-69.7%)。Mycetoma主要在苏丹报告,特别是在苏丹中部(37%-76.6%的病例)。据报告,菲律宾和乌干达的年发病率为0.1/100000人和0.32/100000人/十年,分别。在乌干达,在连续两个10年期间(2000-2009年和2010-2019年),发现发病率从3.37下降至0.32/100000人.以社区为基础,多管齐下的预防计划使截肢率从62.8%降至11.9%。使用预先指定的标准,没有抗真菌药物敏感性的研究,死亡率,并确定了住院时间。未来的研究应该包括更大的队列研究,更大的药敏试验,和全球监测,以制定循证治疗指南,并更准确地确定发病率和随时间推移的趋势。
    The World Health Organization, in response to the growing burden of fungal disease, established a process to develop a fungal priority pathogens list. This systematic review aimed to evaluate the epidemiology and impact of eumycetoma. PubMed and Web of Science were searched to identify studies published between 1 January 2011 and 19 February 2021. Studies reporting on mortality, inpatient care, complications and sequelae, antifungal susceptibility, risk factors, preventability, annual incidence, global distribution, and emergence during the study time frames were selected. Overall, 14 studies were eligible for inclusion. Morbidity was frequent with moderate to severe impairment of quality of life in 60.3%, amputation in up to 38.5%, and recurrent or long-term disease in 31.8%-73.5% of patients. Potential risk factors included male gender (56.6%-79.6%), younger age (11-30 years; 64%), and farming occupation (62.1%-69.7%). Mycetoma was predominantly reported in Sudan, particularly in central Sudan (37%-76.6% of cases). An annual incidence of 0.1/100 000 persons and 0.32/100  000 persons/decade was reported in the Philippines and Uganda, respectively. In Uganda, a decline in incidence from 3.37 to 0.32/100  000 persons between two consecutive 10-year periods (2000-2009 and 2010-2019) was detected. A community-based, multi-pronged prevention programme was associated with a reduction in amputation rates from 62.8% to 11.9%. With the pre-specified criteria, no studies of antifungal drug susceptibility, mortality, and hospital lengths of stay were identified. Future research should include larger cohort studies, greater drug susceptibility testing, and global surveillance to develop evidence-based treatment guidelines and to determine more accurately the incidence and trends over time.

    目的:描述澳大利亚犬和猫鼻隐球菌病12年的CT表现。
    方法:从2008年到2020年,诊断为鼻隐球菌病的12只狗和9只猫。
    方法:比较了澳大利亚兽医转诊中心登记病例的CT表现。比较了一组进行隐球菌物种形成的患者(n=6只狗;n=3只猫)和地理住所的疾病严重程度。
    结果:狗表现出弥漫性疾病,影响许多鼻腔区域和鼻窦。猫表现出更多的局灶性鼻和鼻咽疾病。狗更有可能有鼻腔肿块,而猫更可能有鼻咽肿块。Cribriform平板溶解在狗中很常见,但在猫中没有观察到。鼻窦骨溶解是两个物种的共同特征。下颌淋巴结在狗中常见肿大,而在猫中,咽后淋巴结肿大的可能性更大。与隐球菌的致病种有关的疾病严重程度或病变分布没有明显差异,尽管为了确定这一发现是否可靠,有必要进行适当的前瞻性研究.
    结论:有许多研究描述了临床特征,治疗,以及猫和狗的隐球菌病的结果。据我们所知,以前只有一项研究描述了鼻隐球菌病的CT特征,在北美的一部分进行。我们的研究描述了澳大利亚犬科动物和猫科动物的鼻隐球菌的CT特征,增加新的相关观察,同时加强报告的放射学观察。
    OBJECTIVE: To describe the CT findings of Australian dogs and cats with nasal cryptococcosis over a 12-year period.
    METHODS: 12 dogs and 9 cats diagnosed with nasal cryptococcosis from 2008 through 2020.
    METHODS: CT findings were compared among enrolled cases from Australian veterinary referral centers. Disease severity was compared between a subset of patients with cryptococcal speciation performed (n = 6 dogs; n = 3 cats) and geographic domicile.
    RESULTS: Dogs demonstrated diffuse disease affecting numerous nasal regions and sinuses. Cats displayed more focal nasal and nasopharyngeal disease. Dogs were more likely to have a nasal mass, whereas cats were more likely to have a nasopharyngeal mass. Cribriform plate lysis was common in dogs but not observed in cats. Sinonasal osteolysis was a common feature in both species. Mandibular lymph nodes were commonly enlarged in dogs, whereas in cats, the retropharyngeal lymph nodes were more likely enlarged. There was no obvious difference in disease severity or lesion distribution in relation to the causal species of Cryptococcus, although to determine if this finding is robust, an appropriately powered prospective study is warranted.
    CONCLUSIONS: There are numerous studies describing the clinical features, treatment, and outcomes of dogs and cats with cryptococcosis. To the best of our knowledge, there is only 1 previous study describing the CT features of nasal cryptococcosis, undertaken in one part of North America. Our study describes the CT features of nasal Cryptococcus sp in an Australian canine and feline cohort, adding new pertinent observations while reinforcing reported radiological observations.

    副孢子菌病(PCM)是拉丁美洲国家的全身性真菌病,是人类发病率和死亡率最重要的真菌疾病之一。PCM也在一些动物物种如狗中被描述。在这项研究中,我们描述了狗的PCM疾病的新病例,该病例与文献中先前的记录不同,其中包括真菌皮炎的进行性演变,导致鼻子变形病变。就像在人类病人身上发现的,和针对gp70而不是gp43的体液反应,gp70是人类PCM的主要诊断抗原。通过ITS和部分gp43基因系统发育分析的临床分离株被分组在巴西副球菌复合体中。该病例描述了一些可能有助于提高对犬副球藻病的诊断和理解的特征。
    Paracoccidioidomycosis (PCM) is a systemic mycosis endemic in Latin American countries and one of the most important fungal diseases regarding incidence and mortality in humans. PCM has also been described in some animal species such as dogs. In this study we describe a new case of PCM disease in a dog that differed from previous records in the literature which includes a progressive evolution of fungal dermatitis causing a deforming lesion in the nose, like those found in human patients, and humoral response against gp70 instead of gp43, the major diagnostic antigen for human PCM. The clinical isolate through the ITS and partial gp43 gene phylogenetic analysis was grouped in the Paracoccidioides brasiliensis complex. This case describes several features which may contribute to improving diagnosis and understanding of canine paracoccidioidomycosis.

    F-MF是MF的罕见非经典变体。在脱发的情况下,这应该是一个诊断性的考虑。诊断F-MF的本质是仔细的病史,体检,以及免疫组织学和分子分析的组合(Cureus。2022年;14:e21231,安·沙特医学。2012;32:283,阿曼医学杂志,2012;27:134,国际皮肤素。2016年;55:1396,沙特医学博士,2018年;39:994和案例代表Oncol。2018年;11:436)。
    真菌病(MF)是一种原发性皮肤T细胞淋巴瘤,具有多种亚型。毛囊MF(F-MF)是MF的非经典变体。组织学特征导致毛囊的毛囊化和上皮衬里的损伤,有或没有粘蛋白沉积。一名52岁的男性患者抱怨头皮上的皮肤损伤超过8个月。病变突然出现,随着时间的推移而扩大,变得很痒。进行皮肤穿刺活检。组织学特征包括毛囊上皮中的粘蛋白沉积和致密,主要是滤泡周围非典型淋巴细胞浸润滤泡上皮。淋巴样细胞由CD3阳性T细胞(CD4/CD8阳性T细胞)组成,向前者倾斜。该病例在免疫组织学基础上被诊断为F-MF。F-MF的诊断对于皮肤科医生和皮肤病理学家通常是困难的。不仅需要临床病理相关性,还需要免疫组织化学和分子分析。
    UNASSIGNED: F-MF is a rare non-classic variant of MF. In the case of hair loss, this should be a diagnostic consideration. The essence of the diagnosis of F-MF is a careful medical history, physical examination, and a combination of immunohistological and molecular analyses (Cureus. 2022; 14:e21231, Ann Saudi Med. 2012; 32:283, Oman Med J. 2012; 27:134, Int J Dermatol. 2016; 55:1396, Saudi Med J. 2018; 39:994 and Case Rep Oncol. 2018; 11:436).
    UNASSIGNED: Mycosis fungoides (MF) is a primary cutaneous T-cell lymphoma with multiple subtypes. Follicular MF (F-MF) is a non-classic variant of MF. Histological features entail folliculotropism and damage of the epithelium lining of the hair follicles with or without mucin deposition. A 52-year-old male patient complained of recurrent skin lesions on the scalp over 8 months. The lesions appeared suddenly, enlarged over time, and became itchy. A skin punch biopsy was performed. Histological features included mucin deposits in the epithelium of the hair follicles and dense, predominantly perifollicular atypical lymphocytes infiltrating the follicular epithelium. The lymphoid cells were composed of CD3-positive T cells (CD4/CD8-positive T cells) with a shift in favor of the former. The case was diagnosed as F-MF on an immunohistological basis. The diagnosis of F-MF is often difficult for dermatologists and dermatopathologists alike. Not only clinicopathological correlations but also immunohistochemical and molecular analysis are required.

    在加纳,由于血清学的可用性不足,大多数严重真菌病的实验室诊断是基于组织病理学发现,文化,和分子测试。这项研究的目的是评估加纳诊断的真菌病谱。我们回顾性审查了2012年至2021年加纳三个主要病理实验室的报告,以确定表明存在真菌元素和诊断真菌病的报告。然后提取人口统计,临床病史,感染部位,染色使用和诊断的真菌病细节。在这10年期间,发现107例。没有观察到每年或一段时间内病例数的明显上升和下降趋势。受影响患者的年龄范围为4至86岁。仅在107例病例中的22例(20.6%)中使用了真菌的特殊染色剂。受影响最频繁的部位是鼻音区(34%)。58例(54.2%)确定真菌病类型,包括曲霉病(21),念珠菌病(14),皮肤癣菌病(6),毛霉菌病(3),嗜色真菌病各2例,组织胞浆菌病,Eumycetoma,虫卵真菌病,孢子丝菌病和马拉色菌感染以及隐球菌病和深甲真菌病各一例。在有推定诊断数据的53例(49.5%)中,只有7人(13.2%)在活检前怀疑有真菌病.加纳有广泛的真菌病,包括以前没有报道的地方性真菌病。改进特殊真菌染色剂的使用可以提高产量和真菌病鉴定。实验室诊断能力需要增强,以补充血清学的组织病理学调查,文化,和分子方法。
    在加纳,真菌病的诊断主要基于组织病理学发现。为了欣赏诊断出的各种真菌病,我们回顾了2012年至2021年主要实验室的报告,发现107例病例,包括地方性,罕见,和以前未报告的真菌染色病例异常使用。
    In Ghana, most laboratory diagnoses of severe mycoses are based on histopathology findings due to inadequate availability of serology, culture, and molecular tests. The aim of this study was to evaluate the spectrum of mycoses diagnosed in Ghana. We retrospectively reviewed reports from 2012 to 2021 from three major pathology laboratories in Ghana to identify reports indicating the presence of fungal elements and diagnosis of a mycosis, then extracted demographic, clinical history, site of infection, stain(s), used and diagnosed mycosis details. Over the 10-year period, 107 cases were found. No apparent increasing and decreasing trend in the number of cases per year or in a period was observed. The age range of affected patients was from 4 to 86 years. Special stains for fungi were only used in 22 of 107 (20.6%) of cases. The most frequently affected site was the sino-nasal area (34%). Mycosis type was determined for 58 (54.2%) cases, comprising aspergillosis (21), candidiasis (14), dermatophytosis (6), mucormycosis (3), two cases each of chromoblastomycosis, histoplasmosis, eumycetoma, entomophthoromycosis, sporotrichosis, and Malassezia infection and a single case each of cryptococcosis and deep onychomycosis. Of the 53 (49.5%) cases with presumptive diagnosis data, only seven (13.2%) had a pre-biopsy suspicion of mycosis. There is a wide spectrum of mycoses in Ghana, including endemic mycoses not previously reported. Improving the use of special fungal stains could increase yield and mycoses identification. Laboratory diagnostic capacity needs enhancement to complement histopathology investigations with serology, culture, and molecular methods.
    In Ghana, diagnosis of mycoses is mainly based on histopathology findings. To appreciate the varied mycoses diagnosed, we reviewed the reports of major laboratories from 2012 to 2021 and found 107 cases including endemic, rare, and previously unreported cases with fungal stains unusually used.

    背景:Elastmobranchs目前是全球许多水族馆动物收藏的重要组成部分。它们在人类护理下的维护使我们能够描述和识别新的病原体和影响它们的疾病,以及确定这些疾病的不同治疗方法。松枝畜牧业已经取得了长足的进步。
    方法:在PubMed和其他专业来源(IAAAM档案)的科学数据库上进行搜索。
    结果:该分类组中关于药物治疗的信息很少,治疗缺乏科学基础,而是经常依赖于经验知识。药代动力学研究是确定安全有效的治疗方案的第一步。现有的参考书目表明,在软骨鱼中记录的大多数真菌病是严重的,加剧了抗真菌治疗的事实,遵循硬骨鱼物种的指导方针,在弹枝中无效。唑类似乎是一类有前途的抗真菌药,可用于治疗鲨鱼和射线的全身性真菌病。
    结论:根据本综述的结果,研究这些物种中不同抗真菌药的药代动力学是必要的,以便为软骨鱼的真菌感染提供治疗选择。
    BACKGROUND: Elasmobranchs currently constitute an important part of the animal collection of many aquariums worldwide. Their maintenance under human care has allowed us to describe and identify new pathogens and diseases affecting them, as well as to determine different treatments for these diseases. Great advances in elasmobranch husbandry have been developed.
    METHODS: A search was performed on scientific databases as PubMed and other specialized sources (IAAAM archive).
    RESULTS: Little information on pharmacotherapeutics is available in this taxonomic group, and treatments lack a scientific base and instead are frequently dependent on empirical knowledge. Pharmacokinetic studies are the first step to determining therapeutic protocols that are safe and effective. The available bibliography shows that a majority of the mycoses recorded in cartilaginous fish are severe, aggravated by the fact that the antifungal treatments administered, following the guidelines used for teleost species, are ineffective in elasmobranchs. Azoles appear to be a promising group of antifungals for use in treating systemic mycoses in sharks and rays.
    CONCLUSIONS: Based on the findings of this review, it is essential to investigate the pharmacokinetics of the different antifungals in these species in order to provide therapeutic options for fungal infections in cartilaginous fish.

    犀牛-内脏-脑真菌病不仅由曲霉属引起。和孢子菌属。但也可能与其他稀有物种有关,例如神经孢菌属。,枝孢菌属。和镰刀菌。毛霉菌病与免疫受损状态相关,例如患有糖尿病等合并症的患者。冠状病毒病(COVID)和毛霉菌病的临床症状是严重且无情的,经常没有救命的治疗。
    我们报告了三名COVID-19感染患者,在治疗过程中,他患上了犀牛-眶-脑真菌病,包括口腔受累。在所有三例病例中,通过放射学检查和初步筛查真菌感染(KOHmount)诊断为鼻脑真菌病和口腔受累。开始经验性治疗,但患者对治疗无反应。所有患者甚至在清创和上颌骨切除术后死亡。关于文化,在所有三种情况下都分离出了罕见的真菌,在参考实验室的帮助下,被鉴定为神经孢子菌,枝孢霉和镰刀菌。神经孢菌被认为对人类无致病性。枝孢菌是在所有气候条件下的土壤中发现的一种脱毛真菌,与播散或大脑感染有关;镰刀菌,尽管与其他细菌一起被认为是皮肤和呼吸道粘膜的腐生定植剂,是全球真菌性角膜炎的常见原因。
    在有/没有其他危险因素的情况下,由于COVID-19引起的免疫系统改变会导致真菌共感染,这对患者来说是致命的。重要的是要意识到COVID-19患者,特别是那些病危的人,可能会继发真菌感染,早期检测至关重要。
    UNASSIGNED: Rhino-Orbito-cerebral mycoses are not only caused by Aspergillus spp. and Zygomycetes spp. but also can be associated with other rare species such as Neurospora spp., Cladosporium spp. and Fusarium spp. Mucormycosis is associated causatively with immunocompromised states, for example patients with comorbidities such as diabetes mellitus. Clinical symptoms of coronavirus disease (COVID) and mucormycosis in tandem are critical and relentless, frequently with no life-saving treatment.
    UNASSIGNED: We report three patients with COVID-19 infection, who during the course of treatment developed rhino-orbital-cerebral mycosis including oral cavity involvement. Rhinocerebral mycosis along with oral cavity involvement was diagnosed by radiological investigations and preliminary screening for fungal infection (KOH mount) in all three cases. Empirical treatment was started but patients did not respond to treatment. All patients died even after debridement and maxillectomy. On culture, rare species of fungi were isolated in all three cases which, with the help of a reference laboratory, were identified as Neurospora, Cladosporium and Fusarium. Neurospora is considered nonpathogenic to humans. Cladosporium is a dematiaceous fungus found in soil in all climates, associated with disseminated or cerebral infections; and Fusarium, though considered a saprophytic colonizer of skin and respiratory mucosa along with other bacteria, is a common cause of mycotic keratitis worldwide.
    UNASSIGNED: Immune system modifications due to COVID-19 with/without other risk factors can result in fungal co-infections that prove to be fatal for the patients. It is vital to be aware that COVID-19 patients, particularly those who are critically ill, may acquire secondary fungal infections and early detection is critical.

    伏立康唑相关的肝毒性是一种常见病,通常表现为肝酶升高,并可导致药物停药。需要仔细监测伏立康唑相关的肝毒性,但没有针对这种情况的特定血浆生物标志物。代谢组学已成为研究与药物诱导毒性相关的生物标志物的有前途的技术。这项研究的目的是使用靶向代谢组学来评估七种内源性代谢物作为伏立康唑相关肝毒性的潜在生物标志物。接受伏立康唑治疗药物监测的患者分为肝毒性组(18例)或对照组(153例)。使用超高效液相色谱和质谱联用分析血浆样品。比较两组的代谢物浓度。由逻辑回归产生的受试者工作特征(AUROC)曲线下的面积用于将这7种代谢物的浓度与伏立康唑谷浓度和常规肝脏生物化学测试相关联。与对照组相比,肝毒性组的胆酸和α-酮戊二酸水平显着升高(假发现率校正P<0.001和P=0.024)。代谢产物糖胆酸(AUROC=0.795)和α-酮戊二酸(AUROC=0.696)优于伏立康唑谷浓度(AUROC=0.555),并接近碱性磷酸酶(AUROC=0.876)和总胆红素(AUROC=0.815)的表现。一组糖胆酸盐联合伏立康唑谷浓度(AUROC=0.827)显着提高了伏立康唑谷浓度单独预测肝毒性的性能。总之,整合甘氨胆酸盐和伏立康唑谷浓度的小组在鉴定伏立康唑相关肝毒性方面具有巨大潜力.
    Voriconazole-associated hepatotoxicity is a common condition that generally manifests as elevated liver enzymes and can lead to drug discontinuation. Careful monitoring of voriconazole-associated hepatotoxicity is needed but there are no specific plasma biomarkers for this condition. Metabolomics has emerged as a promising technique for investigating biomarkers associated with drug-induced toxicity. The aim of this study was to use targeted metabolomics to evaluate seven endogenous metabolites as potential biomarkers of voriconazole-associated hepatotoxicity. Patients undergoing therapeutic drug monitoring of voriconazole were classified into a hepatotoxicity group (18 patients) or a control group (153 patients). Plasma samples were analysed using ultra-high-performance liquid chromatography coupled to mass spectrometry. Metabolite concentrations in the two groups were compared. Areas under the receiver operating characteristic (AUROC) curves generated from logistic regressions were used to correlate the concentrations of these seven metabolites with voriconazole trough concentrations and conventional liver biochemistry tests. Glycocholate and α-ketoglutarate levels were significantly higher in the hepatotoxicity group compared with the control group (false discovery rate-corrected P < 0.001 and P = 0.024, respectively). The metabolites glycocholate (AUROC = 0.795) and α-ketoglutarate (AUROC = 0.696) outperformed voriconazole trough concentrations (AUROC = 0.555) and approached the performance of alkaline phosphatase (AUROC = 0.876) and total bilirubin (AUROC = 0.815). A panel of glycocholate combined with voriconazole trough concentrations (AUROC = 0.827) substantially improved the performance of voriconazole trough concentrations alone in predicting hepatotoxicity. In conclusion, the panel integrating glycocholate with voriconazole trough concentrations has great potential for identifying voriconazole-associated hepatotoxicity.

    作为当前医生工具的趋势,ChatGPT可以筛选大量信息,并通过易于理解的对话解决问题,最终提高效率。真菌病目前面临着巨大的挑战,包括高真菌负担,高死亡率,抗真菌药物的选择有限,耐药性增加。为了应对这些挑战,我们向ChatGPT询问了基于真菌感染情景的问题,并评估了其适当性,一致性,和潜在的陷阱。我们得出结论,ChatGPT可以为大多数提示提供令人信服的响应,包括诊断,检查建议,治疗和合理用药。此外,我们总结了在真菌病中令人兴奋的未来应用,比如临床工作,科学研究,教育和医疗保健。然而,实施的最大障碍是个人建议的不足,及时的文学更新,一致性,准确性和数据安全性。为了充分把握机会,我们需要解决这些障碍并管理风险。我们期望ChatGPT将成为真菌病战场上的新武器。
    As current trend for physician tools, ChatGPT can sift through massive amounts of information and solve problems through easy-to-understand conversations, ultimately improving efficiency. Mycosis is currently facing great challenges, including high fungal burdens, high mortality, limited choice of antifungal drugs and increasing drug resistance. To address these challenges, We asked ChatGPT for fungal infection scenario-based questions and assessed its appropriateness, consistency, and potential pitfalls. We concluded ChatGPT can provide compelling responses to most prompts, including diagnosis, recommendations for examination, treatment and rational drug use. Moreover, we summarized exciting future applications in mycosis, such as clinical work, scientific research, education and healthcare. However, the largest barriers to implementation are deficits in indiviudal advice, timely literature updates, consistency, accuracy and data safety. To fully embrace the opportunity, we need to address these barriers and manage the risks. We expect that ChatGPT will become a new weapon in in the battlefield of mycosis.
