【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 investigate whether de-escalation antibacterial therapy would be helpful to antifungal treatment in patients with invasive pulmonary fungal infection( IPFI) .Methods A prospective study was conducted in 174 IPFI patients( male 106, female 68) in the Second Hospital of Hebei Medical University from January 2008 to July 2010. The clinical data was collected including symptoms, physical signs,microbiological results, treatment and prognosis, etc. The therapeutic results were compared between the patients who received or did not receive de-escalation antibacterial therapy. Results The predominant pathogenic fungus was Candida albicans, which accounted for 59. 7% of IPFI. The effect of antifungal therapy showed statistically significant difference between the patients who received de-escalation antibacterial therapy and the patients who did not ( 60. 0% vs. 34. 5% , P =0. 001) . Conclusion The deescalation use of antibacterial therapy would be helpful to antifungal efficacy.
【摘要】 目的 探討老年慢性阻塞性肺疾病(COPD)患者院內肺部真菌感染的可能易患因素、感染時間、臨床特征、感染常見真菌與預后。 方法 回顧性分析36例65歲以上COPD 院內肺部真菌感染患者與同期40例65歲以上COPD院內肺部非真菌感染患者的臨床資料。 結果 老年COPD患者院內肺部真菌感染的可能易患因素與長期使用廣譜抗生素、糖皮質激素,低蛋白血癥、粒細胞減少相關;吸煙時間較長及每年住院次數增多也是老年COPD患者發生院內肺部真菌感染的可能易感因素;約1/3患者肺部真菌發生在入院1~2周,臨床特征無特異性;病原菌主要為白色念珠菌(8055%),胸部X線表現以支氣管肺炎及團塊影改變為主,預后較差。 結論 老年COPD患者若長期使用廣譜抗生素和(或)糖皮質激素,有低蛋白血癥或粒細胞減少,可能會并發院內肺部真菌感染,預后較差,長期吸煙及多次住院患者也應提高警惕,重視可能易患因素并盡早采取預防與治療措施,減少死亡的發生。【Abstract】 Objective To investigate the possible risk factors of nosocomial pulmonary fungal infection, infection time, the clinical features, common infection fungal and prognosis of elderly patients with chronic obstructive pulmonary disease (COPD). Methods The clinical data of 36 patient of COPD complicated with nosocomial pulmonary fungal infection over 65 years old and 40 patients without nosocomial pulmonary fungal infection were retrospectively analyzed. Results Longterm use of broadspectrum antibiotics and (or) glucocorticoid, hypoalbuminemia, neutropenia, smoking for a long time, and hospitalizations were risk factors for nosocomial pulmonary fungal infection in elderly COPD patients. In about 1/3 of patients, nosocomial pulmonary fungal infection occurred within one to two weeks of hospitalization. The clinical features were nonspecific. Pathogens were mainly Candida albicans (8055%). Bronchial pneumonia and group block were the main findings in Chest Xray. The prognosis was poor. Conclusion Elderly patients with COPD are prone to nosocomial pulmonary fungal infection if they have hypoproteinemia, neutropenia or use longterm broadspectrum antibiotics and (or) glucocorticoids.
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 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 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 morbility，risk factors，etiology，treatment and outcome of nosocomial pulmonary fungal infections in respiratory intensive care unit（RICU）.Methods Forty-seven respiratory RICU patients with nosocomial pulmonary fungal infections between July 2000 and June 2005 were retrospectively analyzed.Results All of the 47 cases were clinically diagnosed as probable nosocomial pulmonary fungal infections，with the morbidity of 10.8% significantly higher than general wards（1.8%，Plt;0.005）.COPD and bacterial pneumonia were the major underlying diseases of respiratory system with a percent of 38.30% and 36.17%，respectively.Forty-one patients (87.2%) had risk factors for fungal infections.Compared with general wards，the proportion of Aspergillosis was higher in RICU without significant difference (Pgt;0.1)；the proportions of Candida glabrata and Candida tropicalis were higher too，but that of Candida krusei was relatively low.The effective rate of antifungal treatment was 79.1% and fluconazol was the most common used antifungal agents.The mortality of fungal infection in RICU was higher than that of general wards but without significant difference（Pgt;0.1）.Conclusion The morbidity of nosocomial pulmonary fungal infection in respiratory RICU is higher than that in general wards.The proportions of infection caused by Aspergilli and some Candida resistant to fluconazol is relatively high.Early and effective treatment is needed in these patients considering the poor prognosis.
