    念珠菌,人类皮肤的共生居民,被认为是各种身体表面皮肤念珠菌病的原因。免疫系统较弱的人,特别是那些有免疫抑制症状的人,更容易受到这种感染。糖尿病,一种主要的代谢紊乱,已经成为诱导免疫抑制的关键因素,从而促进念珠菌定植和随后的皮肤感染。这篇全面的综述研究了糖尿病患者中不同类型的白色念珠菌引起的皮肤念珠菌病的患病率。它探讨了致病性的潜在机制,并提供了建议的预防措施和治疗策略的见解。糖尿病显著增加口腔和食道念珠菌病的易感性。此外,它可以导致女性外阴阴道念珠菌病,男性念珠菌龟头炎,糖尿病患儿的尿布念珠菌病。糖尿病个体也可能在他们的指甲上经历念珠菌感染,手和脚。值得注意的是,糖尿病似乎是肥胖者中的intertrigo综合征和义齿佩戴者中的牙周病的危险因素。总之,糖尿病和皮肤念珠菌病之间错综复杂的关系需要全面了解以制定有效的管理计划。进一步的调查和跨学科的合作努力对于解决这一多方面的挑战和发现新的治疗方法至关重要。管理和预防两种健康状况,包括开发更安全、更有效的抗真菌药物。
    Candida species, commensal residents of human skin, are recognized as the cause of cutaneous candidiasis across various body surfaces. Individuals with weakened immune systems, particularly those with immunosuppressive conditions, are significantly more susceptible to this infection. Diabetes mellitus, a major metabolic disorder, has emerged as a critical factor inducing immunosuppression, thereby facilitating Candida colonization and subsequent skin infections. This comprehensive review examines the prevalence of different types of Candida albicans-induced cutaneous candidiasis in diabetic patients. It explores the underlying mechanisms of pathogenicity and offers insights into recommended preventive measures and treatment strategies. Diabetes notably increases vulnerability to oral and oesophageal candidiasis. Additionally, it can precipitate vulvovaginal candidiasis in females, Candida balanitis in males, and diaper candidiasis in young children with diabetes. Diabetic individuals may also experience candidal infections on their nails, hands and feet. Notably, diabetes appears to be a risk factor for intertrigo syndrome in obese individuals and periodontal disorders in denture wearers. In conclusion, the intricate relationship between diabetes and cutaneous candidiasis necessitates a comprehensive understanding to strategize effective management planning. Further investigation and interdisciplinary collaborative efforts are crucial to address this multifaceted challenge and uncover novel approaches for the treatment, management and prevention of both health conditions, including the development of safer and more effective antifungal agents.

    在免疫功能正常的个体中,血液播散的曲霉脊柱炎很少见。临床,成像,这种情况的病理表现并不具体。因此,这种疾病容易误诊和漏诊。全身抗真菌治疗是曲霉菌脊柱炎的主要治疗方法。我们报告了一例免疫功能正常的患者的血液播散性杂色曲霉脊柱炎。第一次抗真菌治疗持续了4个月,但是曲霉性脊柱炎几个月后又复发了。开始第二个抗真菌治疗疗程至少1年,后续行动一直在进行。目前,没有复发。
    Blood-disseminated Aspergillus spondylitis in immunocompetent individuals is rare. The clinical, imaging, and pathological manifestations of this condition are not specific. Therefore, this disease is prone to misdiagnosis and a missed diagnosis. Systemic antifungal therapy is the main treatment for Aspergillus spondylitis. We report a case of blood-disseminated Aspergillus versicolor spondylitis in a patient with normal immune function. The first antifungal treatment lasted for 4 months, but Aspergillus spondylitis recurred a few months later. A second antifungal treatment course was initiated for at least 1 year, and follow-up has been ongoing. Currently, there has been no recurrence.

    该报告描述了子宫胚真菌病的罕见发生,在北美流行的皮肤芽胞杆菌感染的非典型全身表现。专注于一名51岁的有免疫能力的女性,表现出腹痛和不规则的阴道出血,它强调了反映常见妇科疾病的症状所带来的复杂诊断障碍。尽管记录的病例不到10例,子宫受累的稀有性凸显了增加临床怀疑的必要性。多方面的诊断策略综合了风险因素,旅行史,成像,和组织病理学检查。强调由妇科医生主持的多学科治疗,病理学家,和传染病专家,抗真菌药物的利用,尤其是伊曲康唑,是关键的。解决文献的稀缺性和这种疾病与普遍疾病的临床相似性,进一步的研究对于设计定制的子宫胚菌病诊断和治疗方案至关重要。这项研究通过提供对几乎没有记载的疾病的批判性见解,丰富了现有的文献。贡献了对临床理解和管理策略至关重要的新观点。
    The report delineates the rare occurrence of uterine blastomycosis, an atypical systemic presentation of Blastomyces dermatitidis infection prevalent in North America. Focused on a 51-year-old immunocompetent female displaying abdominal pain and irregular vaginal bleeding, it underscores the intricate diagnostic hurdles posed by symptoms mirroring common gynecological conditions. Despite fewer than 10 recorded cases, the rarity of uterine involvement highlights the imperative for heightened clinical suspicion. The multifaceted diagnostic strategy integrates risk factors, travel history, imaging, and histopathological examinations. Emphasizing a multidisciplinary treatment helmed by gynecologists, pathologists, and infectious disease specialists, the utilization of antifungal agents, notably itraconazole, is pivotal. Addressing the scarcity of literature and the condition\'s clinical resemblance to prevalent ailments, further research becomes paramount in devising tailored diagnostic and treatment protocols for uterine blastomycosis. This study enriches the existing literature by providing critical insights into a scarcely documented condition, contributing novel perspectives essential for clinical understanding and management strategies.

    目的:扁豆是一种常见的导致脑脓肿的黑色素化真菌。过去,许多病例来自亚洲,尤其是来自印度。迟到了,在亚洲以外的地方,案件有所增加,因此有必要对案件进行审查。
    方法:我们介绍了一例由C.bantiana引起的致命性脑性真菌病,并对2015年至2022年报告的由C.bantiana引起的培养证实的脑脓肿进行了系统评价。
    结果:在发现的39例中,大多数(68%)免疫功能低下。各种临床表现为头痛(53%),偏瘫(34%),视觉障碍(25%),感官改变(18%),失语/构音障碍(12%)和癫痫发作(9%)。在18例(60%)患者中观察到孤立的病变。在发生的顺序中,病变位于额叶(30%),颞叶(27%)和顶叶(20%)区域。共感染5例,如同时检出诺卡氏菌肺炎2例,脑脓肿中的弓形虫DNA,在脑脓肿病例中,共存的新型肺隐球菌感染和共存的念珠菌各1例。84%的病例进行了手术干预。抗真菌治疗包括伏立康唑(80%),两性霉素B脂质体(76%),5-氟胞嘧啶(30%),泊沙康唑(10%),和两性霉素B脱氧胆酸盐(6%)。总死亡率为50%,与亚洲(63.6%)相比,亚洲以外地区的死亡率较低(42%),尽管没有统计学意义。
    结论:C.bantiana脑脓肿是一种全球新兴的感染。下一代测序是即将到来的有希望的诊断测试。早期完全切除病灶并使用有效的抗真菌药物可以改善预后。
    OBJECTIVE: Cladophialophora bantiana is a wonted melanized fungus causing brain abscess. In past many cases were reported from Asia, particularly from India. Of late, there is a rise in cases in places besides Asia and hence a review of the cases is warranted.
    METHODS: We present a case of fatal cerebral phaeohyphomycosis caused by C. bantiana and conduct a systematic review of culture confirmed brain abscess due to C. bantiana reported between 2015 and 2022.
    RESULTS: Of the 39 cases found, majority (68%) were immunocompromised. The various clinical presentations were headache (53%), hemiparesis (34%), visual disturbance (25%), altered sensorium (18%), aphasia/dysarthria (12%) and seizures (9%). Isolated lesion was observed in 18 (60%) patients. In the sequence of occurrence, the lesions were in frontal (30%), temporal (27%) and parietal (20%) region. There were five cases with coinfections such as concurrent detection of Nocardia pneumonia in two cases, toxoplasma DNA in brain abscess, coexisting pulmonary Cryptococcus neoformans infection and coexisting Candida in a case of brain abscess in one case each. Surgical intervention was performed in 84% cases. Antifungal therapy included voriconazole (80%), liposomal amphotericin B (76%), 5-fluorocytosine (30%), posaconazole (10%), and amphotericin B deoxycholate (6%). The overall mortality was 50% with lower mortality (42%) in regions outside Asia compared to Asia (63.6%) though not statistically significant.
    CONCLUSIONS: C. bantiana brain abscess is an emerging infection worldwide. Next generation sequencing is an upcoming promising diagnostic test. Early complete excision of the lesion with effective antifungals may improve the outcome.

    曲霉菌骨折相关性感染(FRI)是一种罕见的,而是创伤手术的严重并发症.曲霉菌骨髓炎的最佳抗真菌治疗方法,包括FRI,尚未建立,因为只有病例被记录,关于抗真菌药物骨渗透的数据很少。我们描述了一名患有胫骨烟曲霉FRI的患者,该患者在伏立康唑治疗期间出现肝功能紊乱后接受了伊沙康康唑治疗。伊沙武康唑,通过血浆酯酶水解前药isavuconazonsulate后形成的活性部分,以200毫克q24小时的维持剂量给药,然后是150mgq24h。患者完成了为期六个月的抗真菌治疗过程。尽管在停止治疗后的6个月随访期间未实现骨折愈合,未观察到FRI的确证征象.此外,本研究进行了两次文献检索,目的是回顾有关曲霉菌骨髓炎的抗真菌治疗和抗真菌药物的骨渗透的现有数据.108例曲霉骨髓炎,包括六例(5.6%)FRI病例,已确定。伏立康唑和两性霉素B(脂质制剂)是最常用的抗真菌药。在3例(2.8%)中,以阿武康唑被规定为挽救疗法。报告了伊曲康唑抗真菌骨渗透的数据,伏立康唑,两性霉素B,anidulafungin和5-氟胞嘧啶。伊沙武康唑可能是治疗曲霉骨髓炎的有希望的替代药物。然而,需要标准化的病例文件来评估伊沙武康唑和其他抗真菌药物治疗曲霉骨髓炎的疗效,包括FRI。
    Aspergillus fracture-related infection (FRI) is a rare, but severe complication in trauma surgery. The optimal antifungal treatment for Aspergillus osteomyelitis, including FRI, has not been established yet, as only cases have been documented and data on bone penetration of antifungal drugs are scarce. We describe a patient with Aspergillus fumigatus FRI of the tibia who was treated with isavuconazole after developing liver function disturbances during voriconazole therapy. Isavuconazole, the active moiety formed after hydrolysis of the prodrug isavuconazonium sulfate by plasma esterases, was administered in a maintenance dose of 200 mg q24 h, followed by 150 mg q24 h. The patient completed a six-month antifungal treatment course. Although fracture union was not achieved during six months of follow-up after therapy cessation, no confirmatory signs of FRI were observed. Additionally, two literature searches were conducted to review available data on antifungal treatment of Aspergillus osteomyelitis and bone penetration of antifungals. One hundred and eight cases of Aspergillus osteomyelitis, including six (5.6%) FRI cases, were identified. Voriconazole and (lipid formulations of) amphotericin B were the most commonly used antifungals. In three (2.8%) cases isavuconazole was prescribed as salvage therapy. Data on antifungal bone penetration were reported for itraconazole, voriconazole, amphotericin B, anidulafungin and 5-fluorocytosin. Isavuconazole might be a promising alternative for the treatment of Aspergillus osteomyelitis. However, standardized case documentation is needed to evaluate the efficacy of isavuconazole and other antifungals in the treatment of Aspergillus osteomyelitis, including FRI.

    背景:虽然由两种或两种以上不同种类的酵母引起的真菌血症(混合真菌血症,MF)不常见,这可能被低估了。
    目的:本研究旨在确定MF的发病率,患者的临床特征,和抗真菌药敏谱的分离与文献的系统回顾。
    方法:数据来源为PubMed和Scopus。
    方法:研究报告了10次或更多次混合真菌血症发作。
    背景:研究包括2000年1月至2018年8月在Hacettepe大学医院的成人MF发作,土耳其。隔离,分离株的鉴定和抗真菌药敏试验(AST)采用标准真菌学方法.回顾性获得患者数据。根据PRISMA系统评价指南使用相关关键词进行文献检索。确定了总共32例患者的33例MF发作。在所有的真菌血症发作中,MF发生率为3.7%(33/883)。所有患者都有一种或多种基础疾病,其中实体器官癌(50.0%,16/32)是最常见的。总死亡率为51.5%(17/33)。初始治疗最优选的抗真菌药物是氟康唑(48.5%,16/33)和棘白菌素(39.4%,13/33).在15次发作中检测到氟康唑敏感剂量依赖性(S-DD)或耐药的念珠菌。一种近平滑梭菌的分离株被AFST分类为S-DD。所有念珠菌分离物均对棘白菌素类敏感。在两次发作中检测到具有固有抗性/对棘白菌素和氟康唑敏感性降低的非念珠菌酵母。对文献的系统回顾显示,有24项研究报告了十多次MF发作。方法是可变的。据报道,当使用显色琼脂时,检出率有所提高。大多数研究强调检测具有降低的敏感性的分离株。
    结论:虽然罕见,MF率受到检测方法的影响,近年来有所改善。氟康唑和棘白菌素根据目前的指南建议用于初始治疗;然而,检测到对两者都不敏感的分离株。混合感染的检测提供了最佳治疗的机会。
    BACKGROUND: While fungaemia caused by two or more different species of yeasts (mixed fungaemia, MF) is infrequent, it might be underestimated.
    OBJECTIVE: This study aimed to determine the incidence of MF, clinical characteristics of the patients, and antifungal susceptibility profiles of the isolates with a systematic review of the literature.
    METHODS: Data sources were PubMed and Scopus.
    METHODS: Studies reporting ten or more mixed fungaemia episodes.
    BACKGROUND: Study included MF episodes in adults between January 2000 and August 2018 in Hacettepe University Hospitals, Turkey. The isolation, identification and antifungal susceptibility testing (AFST) of the isolates were by standard mycological methods. Patient data were obtained retrospectively. Literature search was performed using relevant keywords according to PRISMA systematic review guidelines. A total of 32 patients with 33 MF episodes were identified. Among all fungaemia episodes, MF incidence was 3.7% (33/883). All patients had one or more underlying disorders among which solid-organ cancer (50.0%, 16/32) was the most common. Overall mortality was 51.5% (17/33). The most preferred antifungal agents for initial treatment were fluconazole (48.5%, 16/33) and echinocandins (39.4%, 13/33). Fluconazole susceptible-dose-dependent (S-DD) or -resistant Candida species were detected in 15 episodes, and an isolate of C. parapsilosis was classified as S-DD by AFST. All Candida isolates were susceptible to echinocandins. Non-candida yeasts with intrinsic resistance/reduced susceptibility to both echinocandins and fluconazole were detected in two episodes. Systematic review of the literature revealed 24 studies that reported more than ten MF episodes. Methodology was variable. Improvement of detection rates was reported when chromogenic agars were used. Most studies underlined detection of isolates with reduced susceptibility.
    CONCLUSIONS: Although rare, the MF rate is affected by the detection methods, which have improved in recent years. Fluconazole and echinocandins were used for initial treatment in accordance with the current guideline recommendations; however, isolates non-susceptible to both were detected. Detection of a mixed infection offers an opportunity for optimum treatment.

    BACKGROUND: Non-albicans Candida prosthetic joint infections (PJIs) are rare. Optimal treatment involves a two-stage revision surgery in combination with an antifungal agent. However, no clear guidelines have been developed regarding the agent or treatment duration. Hence, a broad range of antifungal and surgical treatments have been reported so far.
    OBJECTIVE: To clarify treatment of non-albicans Candida PJIs.
    METHODS: A literature review of all existing non-albicans Candida PJIs cases through April 2018 was conducted. Information was extracted about demographics, comorbidities, responsible species, duration and type of antifungal treatment, type of surgical treatment, time between initial arthroplasty and symptom onset, time between symptom onset and definite diagnosis, outcome of the infection and follow-up.
    RESULTS: A total of 83 cases, with a mean age of 66.3 years, were located. The causative yeast isolated in most cases was C. parapsilosis (45 cases; 54.2%), followed by C. glabrata (18 cases; 21.7%). The mean Charlson comorbidity index was 4.4 ± 1.5. The mean time from arthropalsty to symptom onset was 27.2 ± 43 mo, while the mean time from symptom onset to culture-confirmed diagnosis was 7.5 ± 12.5 mo. A two stage revision arthroplasty (TSRA), when compared to one stage revision arthroplasty, had a higher success rate (96% vs 73%, P = 0.023). Fluconazole was the preferred antifungal agent (59; 71%), followed by amphotericin B (41; 49.4%).
    CONCLUSIONS: The combination of TSRA and administration of prolonged antifungal therapy after initial resection arthroplasty is suggested on the basis of limited data.

    目的:真菌性腹膜炎(FP)是腹膜透析(PD)中一种罕见但破坏性的并发症,考虑到高的技术故障率,发病率和死亡率。这项研究是为了调查FPs关于腹膜炎率,微生物学测试,患者特征,临床特征,抗真菌治疗,和PD患者的临床结果。
    方法:这项单中心研究回顾性分析了2012年6月1日至6月诊断的所有FP发作,2017.所有FP与诊断为细菌性腹膜炎的PD患者以1:5的比例匹配。临床,记录生化特征和腹膜炎发作的详细数据.
    结果:确定了11次真菌性腹膜炎发作(每个患者透析年的发生率为0.0067次)。所有FPs均由念珠菌属引起(使用VITEK2®紧凑型系统进行鉴定和抗真菌药敏试验),包括白色念珠菌(6/11),C.近平滑(4/11)和C.krusei(1/11)。除了C.Krusei,未检测到念珠菌对氟康唑耐药。与细菌性腹膜炎相比(匹配病例,n=55),FP组以前使用抗生素的比率更高(p=0.002),较高的总流出物细胞计数(p=0.007),和较低的血清白蛋白(p=0.01),感染相关手术的发生率较高(p<0.001),高清传输(p=0.001),全因死亡(p=0.006)。女性高患病率(≥50%),无尿症,CCI≥4,低蛋白血症,贫血,在FP患者中也观察到低钾血症。超过一半的FP患者出现胃肠道症状(7/11)和腹膜外感染(6/11)。8例(72.7%)患者手术切除导管,平均滞后5.5天,4例(36.4%)患者在3个月内死亡,6例(54.5%)导致技术失败.
    结论:FP在3个月的随访中导致导管丢失和全因死亡率高,念珠菌是我们中心最常见的病原体。观察到临床特征和易感性模式的变化。胃肠道疾病可能是FP的潜在危险因素。
    OBJECTIVE: Fungal peritonitis (FP) is a rare but devastating complication in peritoneal dialysis (PD), accounting for high rates of technique failure, morbidity and mortality. This study was conducted to investigate FPs with regard to peritonitis rate, microbiology testing, patient characteristics, clinical features, antifungal treatments, and clinical outcomes in patients on PD.
    METHODS: This single-center study retrospectively reviewed all FP episodes diagnosed from June 1, 2012 to June, 2017. All FPs were matched in a 1:5 ratio with PD patients diagnosed with bacterial peritonitis. Clinical, biochemical characteristics and detailed data on peritonitis episodes were recorded.
    RESULTS: Eleven fungal peritonitis episodes (rate of 0.0067 episodes per patient-year on dialysis) were identified. All FPs were caused by Candida species (identification and antifungal susceptibility testing were performed with VITEK 2® compact system), including C. albicans (6/11), C. parapsilosis (4/11) and C. krusei (1/11). Except C. krusei, no Candida resistance to fluconazole was detected. Compared to bacterial peritonitis (matched cases, n = 55), FP group showed higher rate of previous antibiotic use (p = 0.002), higher total effluent cell count (p = 0.007), and lower serum albumin (p = 0.01), higher rate of infection-related surgery (p < 0.001), HD transfer (p = 0.001), and all-cause death (p = 0.006). High prevalence (≥ 50%) of female gender, anuria, CCI ≥ 4, hypoalbuminemia, anemia, and hypokalemia were also observed in FP patients. More than half of the FP patients presented gastrointestinal symptoms (7/11) and extraperitoneal infection (6/11). Eight (72.7%) patients had catheter surgically removed with a median 5.5 lag days, four (36.4%) patients died within 3 months and six (54.5%) cases led to technique failure.
    CONCLUSIONS: FP results in high rates of catheter loss and all-cause mortality in 3 months of follow-up, candida species were the commonest pathogens in our center. Variations of clinical features and susceptibility patterns were observed. Gastrointestinal disorders maybe a potential risk factor for FP.

    紫罗兰脑脓肿很少见,但在移植患者中经常和迅速致命。我们报告了一名63岁的男子,该男子因慢性阻塞性肺疾病接受了肺移植,并出现头痛和神经功能缺损。磁共振成像显示多发性脑脓肿。通过直接对手术活检获得的脑组织进行DNA测序来鉴定C.bantiana。经过6个月的抗真菌治疗,脑脓肿被缺血性后遗症所取代。患者在2个月后突然死于肺部细菌感染。这是在肺移植受者中报道的第二例C.bantiana脑脓肿,根据我们的知识,仅通过医学抗真菌治疗就经历了很长的生存期。我们回顾了文献并讨论了我们的治疗方法。
    Cladophialophora bantiana brain abscesses are rare, but are frequently and quickly lethal in transplanted patients. We report the case of a 63-year-old man who had undergone lung transplantation for chronic obstructive pulmonary disease and presented with headaches and a neurological deficit. Magnetic resonance imaging revealed multiple brain abscesses. C. bantiana was identified by DNA sequencing performed directly on cerebral tissue obtained by surgical biopsy. After 6 months of antifungal treatment, the brain abscesses were replaced by ischemic sequelae. The patient died suddenly 2 months later from a pulmonary bacterial infection. This is the second reported case of C. bantiana brain abscesses in a lung transplant recipient, to our knowledge, who experienced a long survival period with medical antifungal treatment alone. We review the literature and discuss our treatment.

    The introduction of novel antifungal agents for the treatment of invasive fungal disease in hematological malignancies and also changing treatment strategies have had a great impact in managing affected patients. The medical literature includes some important clinical studies that are being used as evidence for guidelines. The problem with these studies and the guidelines is that they are not very easy to interpret, they include controversial issues, and they are not easy to apply to every patient or country. This paper was designed to critically show the main problems associated with these approaches and provide important information that will help Turkish doctors to adopt them in daily clinical practice.
    Hematolojik malignitelerde yeni antifungal ajanların invazif fungal infeksiyonların tedavisine sunulması ve tedavi stratejilerindeki değişmeler, bu hastaların tedavisini önemli şekilde etkilemiştir. Tıp literatüründe halen kılavuzlara kaynak olan bazı önemli klinik çalışmalar vardır. Ancak gerek bu çalışmalar gerekse kılavuzların en önemli sorunları günlük tıp pratiğine uyarlamadaki güçlükler, tartışmalı konular içermeleri ve her hasta ya da ülkeye uyarlama güçlüğü olmasıdır. Bu yazıda bu yaklaşımlarla ilgili önemli sorunlar eleştirel bir bakış açısı ile gözden geçirilmiş ve Türkiyede doktorların günlük tıp pratiklerine uyarlamaları konusunda bilgiler verilmiştir.
