【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.
【摘要】 目的 總結慢性阻塞性肺疾病（chronic obstructive pulmonary disease，COPD） 患者院外用藥情況，并分析其院外用藥情況、痰真菌檢出率以及激素不良反應發生率的變化。 方法 調查2011年1-6月住院的161 例COPD 患者院外用藥情況，將其分為遵醫囑使用糖皮質激素組（A組，包括口服和吸入激素）、使用非準字號藥物組（B組）和未使用以上兩種藥物組（C組），對各組的痰真菌檢出率進行統計學分析，并對A、B組激素不良反應的發生率進行分析。再將現階段的調查結果與2006年同樣研究結果進行比較。 結果 161例患者中使用口服糖皮質激素6例，使用吸入激素29例，使用非準字號藥物32例，未使用以上兩種藥物94例。痰真菌檢出率情況:B組檢出率為62.5%，明顯高于A組的17.14%、C組的27.66%；組間比較有統計學意義（Plt;0.001）。B組的藥物不良反應發生率為37.5%；A組中口服激素發生率為50%，而使用吸入激素發生率為0%。與2006年同樣研究結果比較，B組患者的比例明顯下降，A組患者明顯增多。 結論 使用非準字號藥物的患者，真菌感染的危險性及激素不良反應的發生率較高，健康教育對于減少這些不良現象的發生發揮了重要作用。【Abstract】 Objective To investigate the use of drugs in patients with chronic obstructive pulmonary disease (COPD) outside the hospital, and analyze the detection rate of fungus and the side effects of glucocorticosteroids (GCs), and their changes. Methods We investigated the drugs used outside the hospital in 161 patients with stable COPD between January and June 2011, who were divided into prescribed medication GCs group (group A, including oral GCs group and inhaled GCs group), drugs without authorization by SFDA (DWAS) group (group B) and other drugs group (group C). Then we made a statistical analysis on the detection rate of fungus, and the incidence rate of the side effects of GCs in the three groups. Finally we compared the present findings with the similar studies five years ago. Results Among the 161 patients, 6 took oral GCs, 29 used inhaled GCs, 32 used DWAS, and 94 used other drugs. The detection rate of fungus in group B was 62.5%, obviously higher than the other groups (17.14% in group A, and 27.66% in group B, Plt;0.05). The rate of side effects of GCs in group B was 37.5%, and 50% in oral GCs group, while no side effects of GCs was found in the inhaled GCs group. Compared with the similar study five years ago, the use of DWAS decreased, and the use of prescribed medication GCs among the patients increased significantly. Conclusions Patients taking DWAS have a high incidence rate of mycotic infection and side effects of GCs. Health education plays an important role in reducing the occurrences of these undesirable phenomena.
Objective
To explore the diagnosis value of the low dose multi-slice spiral computed tomography (MSCT) imaging in pulmonary fungal infection in order to improve its diagnosis level.
Methods
CT manifestations of 106 cases of pulmonary fungal infection confirmed by operation, pathology, mycetes cultivation and follow-ups of clinical therapy were retrospectively analyzed. All cases underwent low dose MSCT examinations including CARE dose 4D and sinogram affirmed iterative reconstruction technology, and 6 cases underwent contrast-enhanced CT scanning.
Results
Among the basic MSCT findings of pulmonary fungal infection, they showed patch-nodular type in 54 cases, solid variant in 38 cases, and tumor type in 14 cases. In all cases, 91 cases displayed as mulifocality, 83 cases as polymorphism and 78 cases as polytropy. Among the 106 cases with comparative distinctive MSCT manifestations, bud of branch sign were showed in 39 cases, halo sign in 32 cases, wedge shape consolidation in 19 cases, ice needle sign in 15 cases, crescentic sign in 11 cases, air ring sign in 6 cases, and contra-halo sign in 4 cases. The nodules in the cavities were not enhanced in enhanced scan in 5 cases.
Conclusions
There are some distinctive MSCT findings in patients with pulmonary fungal infection. Pulmonary fungal infection can be diagnosed with typical MSCT findings in close combination with the clinical information.
Objective To evaluate the predicted value of APACHEⅡ score at admission for deep fungal infection（DFI） in patients with severe acute pancreatitis （SAP）.Methods The clinical data of 132 patients with SAP from January 2006 to June 2011 in our hospital were analyzed retrospectively. The receiver operating characteristic curve （ROC） was used for evaluating the predicted value.Results Thirty-nine patients with SAP infected DFI （29.5%）,of which 36 patients （92.3%） infected with Candida albicans,2 patients （5.1%） with Candida tropicalis,1 patient （2.6%） with pearl bacteria.And,among these 39 patients,27 patients （69.2%） infected at single site,12 patients （30.8%） infected at multi-site. The APACHEⅡ score in 39 patients with DFI was higher than that of 93 patients without DFI （17.1±3.8 versus 9.7±2.1, t=14.316,P=0.000）.The ROC for APACHEⅡ score predicting DFI was 0.745（P=0.000）, 95%CI was 0.641－0.849.When the cut off point was 15,it showed the best forecast performance,with specificity 0.81, sensitivity 0.72,Youden index 0.53. Conclusions The APACHEⅡ score at admission can preferably predict DFI in patients with SAP； when the APACHEⅡ score is greater than 15,it prompts highly possible of DFI,so preventive anti-fungal treatment may be necessary.
Objective To summarize the clinical features, predisposing factors, diagnosis, therapeutic outcome, and prognosis of invasive pulmonary fungal infection( IPFI) . Methods 90 cases with pathologically proved IPFI, admitted in non-intensive care unit in Xiangya Hospital from January 2005 to February 2012, were retrospectively analyzed. Results The pathogenic examination revealed Aspergillosis in 56 cases( 62. 2% ) , Cryptococcus in 18 cases( 20. 0% ) , Mucormycosis in 6 cases( 6. 7% ) , and Histoplasma in 6 cases( 6. 7% ) , etc. The underlying diseases were reported in 87 cases, and mainly included COPD, pulmonary tuberculosis, and diabetes mellitus. Cough and expectoration were the common clinical symptoms. 49 patients ( 54. 4% ) received long-term and broad-spectrum antibiotic therapy. The CT results revealed masses type in 25 cases( 27. 8%) , nodule lesions type in 15 cases( 16. 7% ) , lung consolidation type in 22 cases( 24. 4% ) , cavity type in 22 cases( 24. 4% ) , aspergilloma type in 6 cases( 6. 7% ) . 47 patients were clinical diagnosed with IPFI before biopsy with preliminary diagnosis accordance rate of 52. 2% . 31 cases ( 34. 4% ) underwent surgical resection of pulmonary lesions, and no recurrence was detected over two-year follow up. 56 cases ( 62. 2% ) received systemic anti-fugal therapy, and 43 cases( 76. 8% ) were cured or significantly improved. 3 cases ( 3. 3% ) refused any therapy. Conclusions The most frequently isolated pathogen of IPFI is Aspergillosis. The mainly underlying diseases are COPD, pulmonary tuberculosis, and diabetes mellitus. Long-termand broad-spectrum antibiotic therapy may be the major risk factor. Pathological examination is needed for final diagnosis. Surgical procedure can achieve optimal prognosis.
Objective
To analyze the risk factors associated with fungal infections in adult recipients after living donor liver transplantation (LDLT).
Methods
Data of 189 recipients from January 2006 to December 2012 who received LDLT at our center were retrospectively analyzed. Cox regression analysis was used to analyze the risk factors for postoperative fungal infections.
Results
Postoperative fungal infection was found in 12 recipients. The most common infectious site was lung, whereas the most common fungal pathogen was Candida albicans. Multivariate analysis suggested preoperative low albumin level [HR=0.792, 95%CI (0.694, 0.903), P=0.001], massive intraoperative red blood cell transfusion [HR=4.322, 95%CI (1.308, 14.277), P=0.016] and longer postoperative intensive care unit (ICU) stay [HR=3.399, 95%CI (1.004, 11.506), P=0.049] were the independent risk factors for postoperative fungal infections.
Conclusions
Lung is the most common fungal infection site after LDLT. Preoperative low albumin level, massive intraoperative red blood cell transfusion and longer postoperative ICU contribute to fungal infections after LDLT.
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.
