        • Analysis of risk factors for end-stage liver disease complicated with fungal esophagitis

          Objective To investigate the risk factors for end-stage liver disease (ESLD) complicated with fungal esophagitis (FE). Methods The clinical data of ESLD patients who underwent gastroscopy during their hospitalization in the Second Affiliated Hospital of Chongqing Medical University between January 1, 2017 and December 31, 2023 were retrospectively analyzed. The ESLD patients with FE were selected as the study group, and the ESLD patients without FE during the same period were included as the control group by 1∶2 propensity score matching method. Multivariate logistic regression model was used to analyze the risk factors of ESLD complicated with FE. Results A total of 75 ESLD patients with FE and 150 ESLD patients without FE were enrolled. There was no significant difference in age, gender, decompensated cirrhosis, liver cancer, diabetes mellitus, or etiology of ESLD between the two groups (P>0.05). Multivariate logistic regression analysis showed that longer hospital stay [odds ratio (OR)=1.115, 95% confidence interval (CI) (1.069, 1.164)], with invasive procedures [OR=10.820, 95%CI (4.393, 26.647)], and higher total bilirubin [OR=1.015, 95%CI (1.005, 1.024)] were risk factors for ESLD complicated with FE (P<0.05). In the study group, 41 patients were treated with antifungal drugs, and 4 of them developed invasive fungal infection. Among the 34 patients who did not receive antifungal drugs, 10 developed invasive fungal infection. Conclusions ESLD patients with longer hospital stay, worse liver function, and invasive procedures are more likely to develop FE, and regular gastroscopy should be performed. Once FE is found, active antifungal treatment should be taken to reduce the occurrence of invasive fungal infection and improve the prognosis of patients.

        • Traditional laboratory detection methods and metagenomic next-generation sequencing in pulmonary fungal infection diagnosis

          In recent years, due to the extensive usage of immunosuppressant and the rise of patients with cancers and organ transplantation, the incidence rate of invasive fungal infection, especially invasive pulmonary fungal infection, has increased. Besides the clinical manifestations, medical history and imaging, the diagnosis of pulmonary mycosis mainly depends on pathogen detection methods in clinical microbiology laboratory. However, due to the difficulty in fungi culturing and the low sensitivity of smear microscopy, better molecular biology methods are needed. To date, the emergence of metagenomic next-generation sequencing (mNGS) has improved the identification rate of pulmonary fungal infections. mNGS is significantly superior to traditional detection methods in rapid, accurate, and comprehensive determination of fungi from various clinical specimens, especially atypical fungi. However, some problems in mNGS method have to be addressed including sample collection, report interpretation, and its combination with traditional microbiology methods. With the in-depth discussion and solution of the above problems, mNGS will be indispensable to the etiological diagnosis of pulmonary invasive fungal infection.

        • The clinical features and prognostic analysis of visual function damage caused by fungal sphenoid sinusitis

          ObjectiveTo observe the clinical characteristics of patients with visual impairment caused by fungal sphenoid sinusitis and analyze the influencing factors related to visual prognosis. Methods A retrospective clinical study. From January 2006 to December 2020, 44 patients (55 eyes) with visual impairment caused by fungal sphenoid sinusitis confirmed by imaging and pathological examination in the Department of Ophthalmology of Beijing Tongren Hospital were included in the study. Patients was first diagnosed in the Department of Ophthalmology due to monocular or binocular vision loss, or binocular diplopia, limited eye movement and ptosis. All patients underwent visual acuity examination and fundus color photography. CT examination of paranasal sinus or orbit was performed in 37 cases; magnetic resonance imaging (MRI) of paranasal sinus, brain or orbit was performed in 34 cases. All patients underwent endoscopic sinus opening combined with intrasinus lesion clearance; 14 cases were treated with antifungal drugs after operation. The average follow-up time was 59.61±37.70 months. Comparison of clinical characteristics between invasive and non-invasive fungal sphenoid sinusitis were by χ2 test or Fisher exact test. The influencing factors with P<0.2 in univariate analysis were selected for multivariate regression analysis. ResultsAmong the 44 patients, there were 19 males and 25 females; the ratio of male to female was 1:1.3; the average age of visual symptoms was 61.48 ± 12.17 years; 23 cases (52.3%, 23/44) suffered from immune dysfunction, including 21 cases of diabetes mellitus. The visual acuity decreased in 33 cases (44 eyes) (75.0%, 33/44). There were 15 cases of binocular diplopia with eye movement disorder (34.0%, 15/44), including 6 cases with visual impairment. The visual acuity of the affected eye was no light perception-0.8. There were 35 cases with headache (79.5%, 35/44). Nasal symptoms were found in 14 cases (31.8%, 14/44). There were 40 and 4 cases of Aspergillus and Mucor infection in sphenoid sinus, respectively. Among the 37 cases who underwent CT examination of paranasal sinus or orbit, there were soft tissue filling in the sinus cavity, including 19 cases of high-density calcification in the sinus cavity (51.4%, 19/37); bone defect of sinus wall were in 24 cases (64.9%, 24/37). There were 26 cases (70.3%, 26/37) of sinus wall osteosclerosis. MRI of paranasal sinus, brain or orbit was performed in 34 cases. T1WI of sphenoid sinus lesions showed low signal, high signal and equal signal in 14, 10 and 9 cases, respectively; T2WI showed high signal, low signal and equal signal in 13, 16 and 2 cases respectively. After enhancement, the lesions were strengthened in 11 cases, no obvious enhancement in 23 cases, and the surrounding mucosa was thickened and strengthened. The lesions involved the orbital apex and cavernous sinus in 18 and 16 cases, respectively; orbital apex and cavernous sinus were involved in 12 cases. Six months after operation, visual acuity was significantly improved in 27 eyes (65.9%, 27/41); visual acuity did not improve in 14 eyes (34.1%, 14/41). Multivariate regression analysis showed that the change of sinus wall osteosclerosis was associated with higher visual acuity improvement rate (odds ratio= 0.089, 95% confidence interval 0.015-0.529, P=0.008). ConclusionsFungal sphenoid sinusitis related visual impairment is relatively common in elderly female patients with low immune function; monocular vision loss with persistent headache is the most common clinical symptom; imaging findings of sphenoid sinus lesions are an important basis for diagnosis. Sphenoid sinus opening combined with sinus lesion clearance is an effective treatment. After operation, the visual acuity of most patients can be improved. The prognosis of visual acuity was relatively good in patients with hyperplasia and sclerosis of sphenoid sinus wall bone.

        • Discussion on the construction of fungal disease prevention and control system in China from the epidemic of Candida auris

          Candida auris is an emerging multidrug-resistant fungus that has become a significant global public health threat due to its strong resistance to antifungal agents and its ability to spread within healthcare facilities. This paper reviews the global epidemiological trends of Candida auris and the current status of existing prevention and control systems, focusing specifically on pathogen epidemiological characteristics, domestic and international epidemic situations, current prevention and control frameworks, and the construction of prevention networks. In response to the challenges posed by the international spread of Candida auris , China’s fungal disease prevention system should advance towards a more systematic and scientific direction. By integrating resources from medical institutions, disease control agencies, and research institutes, and combining multidisciplinary knowledge and technologies, China should establish a multi-level coordinated prevention and control mechanism to improve its monitoring, prevention, and treatment systems. In the future, China’s fungal disease prevention and control system needs to further strengthen talent cultivation, improve surveillance networks, promote technological innovation, and build a comprehensive, multi-level modern prevention and control system.

        • The value of 1,3-beta-D-glucan assay for diagnosis of invasive fungal disease with automimmune disease

          ObjectiveTo evaluate the diagnostic value of monitoring 1,3-beta-D-glucan (G test) in patients with autoimmune disease complicated with invasive fungal disease (IFD). MethodsA retrospective study was performed in hospitalized patients in the First Affiliated Hospital of Zhengzhou Universisty who were diagnosed as autoimmune disease with lung infection during the immunosuppressive therapy between January 2014 and January 2016. A total of 372 patients were enrolled in this study. All subjects were classified according to the 2006 diagnostic criteria and treatment of invasive pulmonaary fungal infection, with serum 1,3-β-D-glucan results not included in the diagnosis. There were 18 cases with proven IFD, 35 cases with probable IFD, and 70 ceses with possible IFD. Fifty-three patients with proven IFD or probable IFD were as a case group, and another 249 patients with no evidence for IFD were as a control group. The value of the G test for diagnosis of automimmune disease with IFD was analyzed by ROC curve. ResultsThe serum 1,3-β-D-glucan level was significantly higher in the case group when compared with the control group [median (interquartile range): 135.0 (63.1 to 319.0) pg/ml vs. 75.9 (41.2 to 88.1) pg/ml, P<0.05]. When the cut-off value of serum 1,3-β-D-glucan level was set at 93.8 pg/ml, the sensitivity, specificity, positive predictive value, and negative predictive value for diagnosis of autoimmune disease with IFD were 0.65 (95% CI 0.56 to 0.73), 0.87 (95% CI 0.83 to 0.92), 0.70 (95% CI 0.64 to 0.81), and 0.83 (95% CI 0.79 to 0.88), respectively. ConclusionThe 1,3-beta-D-glucan test is a valuable method for diagnosis of IFD in patients with autoimmune disease.
