Methods According to the Cochrane reviewer’s handbook, all the clinical controlled trials involving mycosis fungoides being treated with interferon were retrieved. The Cochrane Collaboration’s software RevMan 5.0.24 was used for meta-analysis. Results Only six papers including 142 patients met the inclusion criteria. Meta-analyses indicated the results as follows: IFN-α monotherapy was more effective than placebo [OR=69.36,95% CI (3.71-1 296.64)] and a traditional Chinese medicine (Di-jing-dan) [OR=35.53,95% CI (1.78-710.56)], but no significant difference was found between INF-α and thymic peptide [OR=15.11, 95% CI (0.71-322.61)], and between IFN-α monotherapy and IFN-α combined with etretinate therapy [OR=3.10, 95% CI (0.79-12.12)]; and there was no significant difference between the efficacy of IFN-γ combined narrowband ultraviolet B (NB-UVB) therapy and that of single NB-UVB therapy [OR=15.00, 95% CI (0.46-485.32)]; Influenza-like side effects occurred to 90% of all the patients, which were usually slight and easy to release. Conclusion Although there are some mild side effects, interferon is safe to treat MF.
Objective To summarize the characteristics of disseminated Penicillium marneffei infection.Methods The clinical, imageological and bacteriological characteristics were summarized by reviewing one case of disseminated Penicillium marneffei infection in an immunocompetent patient diagnosed in our hospital and the related literatures. Results The patient was a 32-year-old Guangdong male, whose main clinical features were fever, cough, and the abscess of pulmonary, tracheomucosa and subcutaneous. Routine blood examination showed leukocytosis. Other laboratory examination revealed multiple lesions of heart, liver, and kidney. Multiple masses histopathology revealed inflammation, but the culture from the purulent exudates were negative and standard antibiotic therapy was useless. Bronchoscope revealed gray nodus on airway mucosa. Under the direction of bacteriologist, final diagnosis of Penicillium marneffei infection was obtained by the fungal culture from the purulent exudates and the deep sputum. Conclusions Penicillium marneffei can infect immunocompetent patients. Disseminated Penicillium marneffei infection should be considered when patients presented with multiple organ lesions and multiple subcutaneous pyogenic masses which can not explained by connective tissue disease or common pyogenic infection, and with epidemiology of southeast life history.
ObjectiveTo analyze the clinical characteristics, prognosis and predisposing factors of coronavirus disease 2019 (COVID-19) associated pulmonary mucormycosis (CAPM), so as to improve people's understanding of the disease.MethodsFrom from September 1, 2021 to July 31, 2024, 11 patients with CAPM who were hospitalized in Beijing Chaoyang Hospital affiliated to Capital Medical University were retrospectively collected, and 22 patients with non-CAPM were included after matching according to the ratio of 1:2. The clinical manifestations, laboratory examinations, imaging features, tracheoscopy, treatment and prognosis of the two groups were analyzed. ResultsThe average age of patients in CAPM group was 59.5 ± 10.6 years, with 81.8% of males; diabetes mellitus (90.9%) was the most common complication. In CAPM group, the median time after the occurrence of mucor after COVID-19 was 13.0 (10.0, 24.0) days. The utilization rate of glucocorticoids in the CAPM group was 63.6% (7/11), which was significantly higher than that in non-CAPM group [13.6% (3/22)], and the difference between the groups was statistically significant (P=0.006). The C-reactive protein level in CAPM group was significantly higher at 93.90 (75.00, 129.00) mg/L than that in non-CAPM group at 26.10 (4.83, 114.03) mg/L, with a statistically significant difference (P=0.040). The CD4+T lymphocyte counts and B lymphocyte counts in CAPM group were 223.00 (66.75, 336.75)/μL and 32.00 (21.75, 55.25)/μL, respectively, which were significantly lower than those in the non-CAPM group 394.00 (206.00, 610.00)/μL and 112.50 (56.00, 159.25)/μL, with statistical differences between the groups (P=0.040, P=0.040). In terms of imaging, the main imaging findings were the involvement of multiple lobes in both groups. 63.6% (7/11) of patients with pulmonary aspergillosis in CAPM group were significantly higher than those(4/22, 18.2%) in non-CAPM group (P=0.017). The incidence of dyspnea in CAPM group was significantly higher than that in non-CAPM group (90.9% vs. 50.0%, 0.027%).ConclusionThe proportion of glucocorticoid use and the proportion of pulmonary aspergillosis in CAPM group are significantly higher, and they are in a more serious state of immunosuppression. Once combined with pulmonary aspergillus , the mortality rate is higher.
Objective
To investigate the clinical manifestation and histopathologic changes of the fungal necrotizing retinochoroiditis.
Methods
Collecting 7 cases of fungal retinochoroiditis with severe immunodepression and loss of visual acuity.Seven removed eyeballs were stained with HE,PAS and silver methenamine,and observed by light microscopy,and in addition,2 of them examined by electron microscopy.Also fungal cultures of blood and affected tissues were performed.
Results
The chief clinical macnifestation included ciliary injection of conjunctiva,opaque aqueous fluid and vitreous and diffuse hemorrhage and greyt white opacity with retinal detachment in severe cases.Pathologic changes included hemorrhage in the retina,chorioretinal tissue necrosis,hyphae in the blood vessels,affected tissue and vitreous.Fungal culture of blood was positive in three cases.Culture of affected tissues was positive in all cases.
Conclusions
Eedogenous fungal infection of choroid and retina may be due to the severe immunodepression of the sufferers and usually causes chorioretinal tissue destruction and blind.

Objective To assess the quality of current domestic literature about enzyme-linked immunosorbent assay (ELISA) for invasive aspergillosis diagnosis by detecting Aspergillus galactomannan (GM) antigen, and to analyze the sources of bias and variability, as well as the diagnostic ability of different thresholds. Methods Both computer-based online search and manual retrieval were employed to identify relevant articles. The statistical information and quality of science were assessed and classified. The data were analyzed using Meta Disc 1.4 software. The best cutoff value for defining a positive test result was selected by summarizing the following statistical indicators as sensitivity, specificity, likelihood ratio (LR) and summary receiver operating characteristic curve (SROC curve), and by calculating the area under the curve (AUC) as well. Results A total of 20 studies among 2658 literatures were included in accordance with the inclusion criteria, and were divided into different groups based on different cutoff values. Though heterogeneity tests showed no threshold effect, and there were other reasons of heterogeneity. So the data were analyzed by random effects model. The results showed that, compared with other groups, the one with cutoff value set at 0.7 (AUC=0.9456, Q= 0.884 6) showed the best accuracy in diagnosing. Conclusion ELISA detection of Aspergillus GM antigen with cutoff value set at 0.7 has important significance in the early diagnosis of invasive aspergillosis, and it can be conducive to reduce mortality in patients at high risk for Aspergillus infection.
Objective To investigate diagnosis and treatment strategies of patients with pulmonary tuberculosis （TB） complicated by Aspergillus infection. Methods Clinical data of 38 patients with pulmonary TB complicated by Aspergillus infection who underwent surgical treatment from January 2008 to December 2010 in Chengdu Infectious Disease Hospital were retrospectively analyzed. There were 23 male patients and 15 female patients with their average age of 37.8 （23-59） years. Preoperatively，all the patients received regular anti-TB treatment for more than 2 weeks，and patients with definite Aspergillus infection received anti-Aspergillus therapy for more than 3 days with consultation of infectious disease physicians. After above treatment，26 patients underwent lobectomy，1 patient underwent right pneumonectomy，and 11 patients underwent left pneumonectomy. All the patients were followed up at the outpatient department after discharge. They were evaluated every 2 weeks in the first 3 months，every 1 month after 3 months，and every 6 months after 1 year. During follow-up，they received acid-fast bacillus smear and sputum culture to check Aspergillus，as well as CT chest scan. Results All the patients successfully received surgical resection of the pulmonary lesion without perioperative death or severe complication. Postoperative pathology examination confirmed pulmonary TB with Aspergillosis infection in all the 38 patients，whose basic diseases included TB cavity in 17 patients，TB-destroyed lung in 12 patients，and post-TB bronchiectasis in 9 patients. All the patients were followed up after discharge for 1.5-4.5 years. During follow-up，they received regular anti-TB therapy for adequate duration in addition to antifungal medications such as voriconazole. None of the 38 patients had recurrence of Aspergillus infection or pulmonary TB. One patient had hemoptysis which was controlled after proper treatment during follow-up. Conclusion Missed diagnosis rate of pulmonary TB complicated by Aspergillus infection is high. Surgical resection of the pulmonary lesion and postoperative medication treatment are the most effective treatment strategies for patients with pulmonary TB complicated by Aspergillus infection.
