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.
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.
Fungal infection is an important clinical problem for patients with immune deficiency or immunosuppression. With deadly fungus infection case increasing, the development of antifungal vaccine attracts the attention of researchers. Dendritic cell (DC) is the unique antigen presenting cell (APC) to trigger the antifungal immune reaction, and recent studies indicate that the targeted vaccination strategy based on DC have prospective antifungal potentials. In this paper, we review the antifungal immunity mechanism and recent development of the targeted DC antifungal strategy.
Objective To explore the pathogens and clinical features of immunocompromised hosts with septicaemia.Methods The data including underlying diseases, peripheral blood granulocyte count, temperature at blood sampling, management and prognosis)of 160 immunocompromised hosts with septicaemia were analyzed retrospectively．Results 8 patients had twice septicaemia in hospital stay and 3 patients had plural pathogenic septicaemia.171 strains of microorganisms were isolated from blood cultured of 160 septic immuno- compromised hosts in which 156 strains (91.2%) were bacteria, 37 strains(21.6%) were gram positive cocci, 6 strains(3.5%) were gram positive bacilli, 113 strains (66.1%) were gram negative bacilli and 15 strains (8.8%) were fungi. Staphylococcus spp (17 strains) and Streptococcus spp (14 strains) were the predominant pathogens among gram positive cocci and Corynebacteria (5 strains ) were the main pathogen in gram positive bacilli while Escherichia coli (60 strains), Klebsiella pneumoniae (20 strains) and Pseudomonas aeruginosa (15 strains) were the most common bacteria in gram negative bacilli. There were 12 strains of Staphylococcus aureus among the 17 strains of Staphylococcus spp, all of them were methicillin sensitive (MSSA). 17 strains of Escherichia coli, 2 strains of Klebsiella pneumoniae and 1 strain of Klebsiella oxytoca produced ESBLs. Candida was the only pathogens of fungemia in this study in which 4 strains of Candida albicans and 11 strains of non-albicans Candida were detected. There were 120 patients(75%) with granulocytopeniain which 103 patients were agranulocytosis. 70% of the 160 paitents had hyperpyrexia. All patients received broad spectrum antibiotics therapy in the study while 58.8% received antifungal drugs at the same time. 20 patients died of septicaemia and 19 patients gave up therapy because of their conditions deteriorated.The overall improvement rate were 75.6%. Conclusions Bacteria are the main pathogens in septicaemia of immunocom- promised host and fungemia is increasing in recent years.Agranulocytosis is a risk factor of septicaemia in immunocompromised hosts. Hyperpyrexia is one of characteristic signs of these patients.
【Abstract】ObjectiveTo investigate the relevant factors for fungal infection following pancreatoduodenectomy and offer the theoretical foundation for preventing the emergence of complications after operation． MethodsMedical records from 562 consecutive patients who underwent pancreatoduodenectomy in this hospital from 1995 to 2005 were retrospectively reviewed by using single factor and noncondition Logistic regression analyse. Results①Seventyeight patients (13.9%) developed invasive fungal infection. The most frequently isolated fungal were Candida albicans accounted for 67.0%， and followed by Candida glabrata, Candida papasilosis and Candida tropicalis and gastrointestinal tract was the most common infection site, followed by respiratory tract, abdominal cavity. ②Fungal infection occurred significantly more often in patients with the length of time in parenteral nutrition, antibiotic use or abdominal cavity complications. Conclusion The most common infection site and isolated fungal associated with pancreatoduodenectomy were gastrointestinal tract and Candida albicans. Abdominal cavity complications such as pancreatic fistula， biliary fistula and abdominal infection and extended use parenteral nutrition and antibiotic are the most important factors leading to invasive fungal infection after pancreatoduodenctomy. Eliminating the various risk factors will decrease the incidence of fungal infection.
Objective To explore the risk factors of invasive fungal infection ( IFI) in respiratory ward. Methods A multi-center, retrospective, case-control study was carried out. Patients from five general hospitals in Chongqing city, diagnosed as fungal infection, or whose respiratory specimens were fungal positive, were retrospectively screened for IFI. Patients with respiratory infection and colonization of nonfungal cases in the same period of hospitalization were enrolled as control. Results Thirty-four patients diagnosed with IFI and 50 patients diagnosed with bacterial infection were analyzed for the risk factors of IFI. The demographic characteristics of patients including age and gender were not different( P gt; 0. 05) , but hospitalization days, carbapenem antibiotic use, chemotherapy, deep venous catheterization, total parenteralnutrition( TPN) , neutropenia, and renal disfunction were different significantly between the IFI group and the control group. Multiple logistic regression analysis showed that carbapenem antibiotic use ( OR = 6. 753) ,central venous catheterization ( OR = 5. 021) and TPN ( OR = 3. 199) were main risk factors of invasive fungal infection. Conclusion The carbapenem antibiotic use, central venous catheterization and TPN are risk factors for IFI in respiratory ward.
Objective To investigate the clinical characteristics and pathogen distribution of community-acquired pneumonia (CAP) combined with type 2 diabetes mellitus (T2DM), based on bronchoalveolar lavage fluid (BALF) metagenomic next-generation sequencing (mNGS) test. Methods In this cross-sectional study, CAP patients with BALF mNGS test were screened from April 2023 to April 2024. The patients were divided into a single CAP group (CAP group) and a CAP combine with T2DM group (CAP+T2DM group). The data of demographics, underlying diseases, complications, and laboratory tests including blood routine, inflammatory parameters, liver and renal functions, random blood glucose (RGB), hemoglobin A1C (HbA1c), and BALF mNGS tests were collected and compared between the two groups. Results Ultimately, 86 patients were included, with 45 in the CAP group and 41 in the CAP+T2DM group. Compared with the CAP group, the CAP+T2DM group had higher platelet count [(272.44±128.57)×109/L vs. (215.00±100.06)×109/L], erythrocyte sedimentation rate [(75.63±35.19) vs. (59.69±34.47) mm/h], RGB [10.8 (9.1, 13.5) vs. 6.5 (5.8, 7.8) mmol/L], HbA1c [8.2% (7.3%, 8.5%) vs. 5.7% (5.5%, 6.1%)], and fungi infection rate (65.9% vs. 40.0%), and the differences were statistically significant between the two groups (P<0.05). Conclusion CAP patients with T2DM have increased levels of platelet and erythrocyte sedimentation rate, and are at higher risk for fungi infection, which potentially leads to worse outcome.
