【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.
ObjectiveTo investigate the role of Aspergillus in the severe refractory exacerbations of chronic obstructive pulmonary disease (COPD).MethodsThe clinical data of two COPD patients suffering from refractory acute exacerbations were analyzed and the relevant literature were reviewed.ResultsTwo patients were male, aging 72 and 64 years respectively. Both of them had a history of frequent acute exacerbations with severe COPD recently. Meanwhile, they received intravenous use of antibiotics repeatedly, one of them took oral corticosteroids to control wheezing, but failed. Their serum Aspergillus-specific IgG antibody was weakly positive. Besides traditional treatment, they received additional antifungal therapy, and the symptoms alleviated. There was no acute exacerbation in the half a year follow-up period after appropriate therapy.ConclusionsAspergillus colonization, sensitization, infection should be considered in patients with severe COPD. When Aspergillus-associated evidence are acquired, antifungal therapy will be unexpected helpful.
ObjectiveTo explore the diagnostic value of endobronchial ultrasonography with a guide sheath (EBUS-GS) for pulmonary fungal disease.MethodsAll patients were collected from January 2015 to December 2018. They were diagnosed with pulmonary fungal disease by tissue biopsy, body fluid or blood test, and without other diseases such as pneumonia, lung cancer, lung abscess, tuberculosis, or organizing pneumonia, etc. After clinical anti-fungal treatment, clinical symptoms were relieved, chest CT lesions were absorbed, laboratory-related checks were turned negative in these patients. All patients underwent bronchoscopy, bronchoalveolar lavage fluid/brush examination, and blood galactomannan antigen test/latex agglutination test. They were divided into an EBUS-GS group and a non-EBUS-GS group according to whether EBUS-GS check was performed. Non-parametric test was used to analyze the diagnostic value of EBUS-GS in pulmonary fungal diseases.ResultsFifty-one patients were included and 20 patients in the EBUS-GS group and 31 patients in the non-EBUS-GS group. The EBUS-GS group had a higher positive rate of pulmonary fungal disease. The diagnostic rates of the EBUS-GS group and the non-EBUS-GS group were statistically different (90.0% vs. 48.4%, P<0.05).ConclusionEBUS-GS can improve the diagnosis rate of pulmonary fungal disease and provides further evidence for a clear diagnosis.
