Available online We report a case of limb-threatening Lomentospora prolificans elbow infection in a 3-year-old immunocompetent boy following a closed fracture. Resolution of infection was achieved following combined aggressive debridement, combined antifungal therapy, voriconazole-loaded bone cement, and antiseptic joint irrigation. This highlights the need for early diagnosis and multi-modal surgical, medical and other novel adjunctive therapies in managing these difficult-to-treat infections. Increased research and improved access to novel antifungal drugs are essential to enhance treatment options for intrinsically multidrug-resistant fungal infections.
我们报告一例危及肢体的增殖性Lomentospora肘感染在一个3岁的免疫功能正常的男孩后闭合性骨折。通过联合积极清创、联合抗真菌治疗、伏立康唑骨水泥和消毒关节冲洗,感染得以解决。这突出了早期诊断和多模式手术、医疗和其他新型辅助治疗来管理这些难以治疗的感染的必要性。加强研究和改善新型抗真菌药物的可及性对于加强对多重耐药真菌感染的治疗选择至关重要。

Cryptococcal endophthalmitis is a rare manifestation of cryptococcal infection, typically occurring in immunocompromised patients. In this case report, we present a 50-year-old female with advanced-stage lung cancer with multiple metastases presenting with blurred vision for 10 days. A diagnostic pars plana vitrectomy revealed Cryptococcus neoformans in the vitreous. She was treated with systemic amphotericin B and flucytosine, followed by fluconazole for consolidation and maintenance, along with intravitreal amphotericin B and voriconazole injections. Her visual acuity improved from counting fingers at 2 feet to 3/60, with a pinhole correction of 6/18 after 10 months of treatment.
隐球菌性眼内炎是一种罕见的隐球菌感染的表现,通常发生在免疫功能低下的患者。在这个病例报告中,我们报告了一位50岁的晚期肺癌女性,伴有多发转移,表现为视力模糊10天。诊断性玻璃体切除发现玻璃体内有新型隐球菌。患者全身性给予两性霉素B和氟胞嘧啶治疗,随后给予氟康唑巩固和维持,同时玻璃体内注射两性霉素B和伏立康唑。经过10个月的治疗,她的视力从2英尺数到3/60,针孔矫正到6/18。

Donor-derived invasive fungal infections among solid organ transplant recipients are rare but sometimes devastating events associated with notable morbidity and mortality. Here we describe two donor-derived fungal infections – one Candida parapsilosis complex infection and one Aspergillus fumigatus infection – that occurred among heart transplant recipients at a quaternary care center. Both recipients survived their infections, though with substantial morbidity despite aggressive surgical intervention and antifungal therapy.
在实体器官移植受者中,供体来源的侵袭性真菌感染是罕见的,但有时是毁灭性的事件,与显著的发病率和死亡率相关。在这里,我们描述了两个供体来源的真菌感染-一个假丝酵母菌复合感染和一个烟曲霉感染-发生在心脏移植受者在第四护理中心。两名受者都存活了下来,尽管有大量的发病率,尽管积极的手术干预和抗真菌治疗。

Cryptococcosis is an opportunistic mycosis caused by Cryptococcus, mainly affecting the immunocompromised. We report a case of pulmonary cryptococcosis within a 31-year-old immunocompetent patient admitted for painful chest swelling evolving for 4 months prior to admission. The chest X-Ray showed a rounded pulmonary opacity. The chest ultrasound revealed a pulmonary abscess diffusing under the skin. Direct examination using the Indian ink and the May-Grunwald Giemsa staining revealed encapsulated yeasts in the pus. The Culture of the pus on the Sabouraud medium with chloramphenicol confirmed the presence of Cryptococcus neoformans. Cryptococcal antigen was positive. This case reminds us that cryptococcosis should be considered even without immunosuppression.
隐球菌病是一种由隐球菌引起的机会性真菌病,主要影响免疫功能低下者。我们报告一例肺隐球菌病在一个31岁的免疫功能正常的病人入院前4个月的胸痛发展。胸部x线显示圆形肺影。胸部超声显示皮下有一个弥漫性肺脓肿。用印度墨水和梅-格伦沃尔德吉姆萨染色法直接检查发现脓液中有包封的酵母。脓液在含氯霉素的Sabouraud培养基上培养证实了新生隐球菌的存在。隐球菌抗原阳性。本病例提醒我们,即使没有免疫抑制,也应考虑隐球菌病。

Cryptococcal meningitis is one of the major causes of death in sub-Saharan Africa among individuals with advanced HIV, and it is typically diagnosed through lumbar puncture (LP). However, LP may be contraindicated in some cases, causing a clinical dilemma and potential delay in treatment. We present the case of a 60-year-old female, newly diagnosed with HIV, who presented with a reduced level of consciousness and a positive serum cryptococcal antigen (CrAg) test (high titer = 1:320). Computerized tomographic (CT) brain imaging showed multiple nodular lesions, peri-lesional edema and a midline shift. Despite the contraindication for LP, a low volume lumbar puncture (1–2 mL) was performed in view of the elevated serum CrAg titers and patient's clinical symptoms, in order to rule in a definitive diagnosis of cryptococcal meningitis or exclude tuberculous meningitis. The patient was treated for cryptococcal meningitis and responded well. In patients with a positive serum CrAg test and contraindications to LP, an elevated titer (>1:160) and neurological symptoms may guide the initiation of definitive treatment for cryptococcal meningitis, however further evaluation is needed.
隐球菌脑膜炎是撒哈拉以南非洲晚期艾滋病毒感染者死亡的主要原因之一,通常通过腰椎穿刺(LP)诊断。然而,LP在某些情况下可能是禁忌,导致临床困境和潜在的治疗延误。我们报告一例60岁女性,新诊断为HIV,表现为意识水平降低,血清隐球菌抗原(CrAg)检测阳性(高滴度= 1:20 20)。计算机断层扫描(CT)显示多发结节性病变,病灶周围水肿和中线移位。尽管LP有禁忌症,但考虑到血清CrAg滴度升高和患者的临床症状,为了明确诊断隐球菌性脑膜炎或排除结核性脑膜炎,我们进行了低容量腰椎穿刺(1-2 mL)。患者接受隐球菌性脑膜炎治疗,反应良好。在血清CrAg试验阳性和LP禁忌症的患者中,滴度升高(1:160)和神经系统症状可能指导隐球菌性脑膜炎开始最终治疗,但需要进一步评估。

Fungal peritonitis in peritoneal dialysis (PD) patients is rare but is associated with high morbidity and mortality. Candida species are the most common causative agents, but infections caused by unusual, often “nonpathogenic,” fungi are being increasingly reported. Hyphopichia burtonii is typically associated with food spoilage and has rarely been reported in human infections.
We describe the case of a 44-year-old female with end-stage renal disease on continuous ambulatory peritoneal dialysis (CAPD) who developed peritonitis caused by Hyphopichia burtonii. Following the identification of the fungus, the patient was put on hemodialysis, the peritoneal dialysis catheter was removed, and he was given fluconazole for two weeks having favorable clinical development.

This report aims to highlight rarity of disseminated histoplasmosis (DH) presenting as adrenal insufficiency and the need for considering it in the differential diagnosis, even in non-endemic areas. A case is presented of a 69-year-old male patient with a background of hypertension and diabetes mellitus, with a persistent fever, significant loss of weight, and general weakness. Imaging studies showed adrenal masses in both adrenal glands, and laboratory tests showed hyperkalemia and hyponatremia. Hormonal tests confirmed the diagnosis of adrenal insufficiency. CT-guided adrenal biopsy confirmed the diagnosis of histoplasmosis. The patient received a 14-day course of Amphotericin B, followed by oral Itraconazole and glucocorticoid substitution therapy, with improvement in adrenal function over a period of time.
本报告旨在强调以肾上腺功能不全为表现的弥散性组织浆菌病(DH)的罕见性,以及在鉴别诊断中考虑其必要性,即使在非流行地区也是如此。本文报告一例69岁男性患者,有高血压和糖尿病背景,持续发热,体重明显减轻,全身无力。影像学检查显示双侧肾上腺肿块,实验室检查显示高钾血症和低钠血症。激素检查证实肾上腺功能不全。ct引导肾上腺活检确诊为组织浆菌病。患者给予两性霉素B 14天疗程,随后口服伊曲康唑和糖皮质激素替代治疗,一段时间内肾上腺功能有所改善。

Fungal peritonitis in peritoneal dialysis (PD) presents significant challenges. We report the second Quambalaria cyanescens-related PD peritonitis in a 53-year-old male. Negative bacterial cultures and a positive galactomannan (GM) index in both PD effluent (PDE) (0.65) and serum (0.98) prompted early PD catheter removal on day 5. Molecular sequencing confirmed Q. cyanescens, with antifungal susceptibility testing revealing resistance to azoles and echinocandins but susceptibility to amphotericin B and isavuconazonium. Treatment with amphotericin B and voriconazole resolved symptoms, with no relapses during a two-year follow-up. This case highlights GM testing's critical role in guiding catheter removal and adherence to the 2022 ISPD Peritonitis Guidelines, ensuring favorable outcomes for rare fungal PD infections.
真菌性腹膜炎在腹膜透析(PD)提出了重大挑战。我们报告一名53岁男性的第二例黄斑线虫相关的PD腹膜炎。PD排出液(PDE)和血清中半乳甘露聚糖(GM)指数均呈阳性(0.65)和阴性(0.98),提示PD导管在第5天早期拔除。分子测序证实了Q. cyanescens,其抗真菌药敏试验显示对唑类和棘白菌素耐药,但对两性霉素B和异唑康唑敏感。两性霉素B和伏立康唑治疗可缓解症状,在两年随访期间无复发。该病例强调了GM检测在指导导管移除和遵守2022 ISPD腹膜炎指南方面的关键作用,确保罕见的真菌性PD感染的良好预后。

This report documents the first human case of Eidernor doerrieniae colonization in a peritoneal dialysis catheter, identified through DNA sequencing after a 52-year-old man observed brownish particles within his catheter. Despite the absence of peritonitis symptoms, prompt catheter removal and antifungal therapy successfully resolved the infection. Fungal cultures revealed cerebriform (brain-like) colonies, confirmed as E. doerrieniae using multi-targeted molecular diagnostics. A wet contamination event three weeks earlier was identified as the likely source. This case underscores the importance of recognizing intraluminal particles as an indicator of fungal colonization and highlights the critical role of timely intervention and advanced diagnostics in preventing fungal peritonitis.
本报告记录了第一例人腹膜透析导管中大肠杆菌定植的病例,该病例是在一名52岁男子在其导管内观察到棕色颗粒后通过DNA测序确定的。尽管没有腹膜炎症状,但及时拔除导管和抗真菌治疗成功地解决了感染。真菌培养显示脑状(脑样)菌落,经多靶点分子诊断证实为大肠杆菌。三周前的一次湿污染事件被确定为可能的源头。该病例强调了识别腔内颗粒作为真菌定植指标的重要性,并强调了及时干预和先进诊断在预防真菌腹膜炎中的关键作用。

Hormonal fluctuations during pregnancy increase susceptibility to Candida infections, typically presenting as vulvovaginal candidiasis, but rarely as oropharyngeal candidiasis. We report a rare case of a woman being pregnant for 27 + 1 weeks with twins with oropharyngeal candidiasis, likely attributed to nutritional anemia and adverse reactions of amoxicillin. Following a thorough literature review and evaluation of medication safety during pregnancy regarding route, dosage, and gestational stage, we treated the patient with fluconazole and piperacillin-tazobactam. The patient fully recovered and successfully delivered two infants via cesarean section at term, with no adverse reactions noted during a six-month follow-up.
怀孕期间的激素波动增加了对念珠菌感染的易感性,通常表现为外阴阴道念珠菌病,但很少表现为口咽念珠菌病。我们报告一例罕见的妇女怀孕27 + 1周双胞胎口咽念珠菌病,可能是由于营养性贫血和阿莫西林不良反应。经过全面的文献回顾和对妊娠期间药物安全性的评估,包括用药途径、剂量和妊娠期,我们给患者使用氟康唑和哌拉西林-他唑巴坦。患者完全康复,并在足月通过剖宫产成功分娩了两个婴儿,在六个月的随访中没有发现不良反应。
