ObjectiveTo explore the efficacy of community-acquired pneumonia (CAP) by tracheoscopy intervention altimeter and analyze and compare its financial burden.MethodsRetrospective analysis of 419 hospitalized patients with CAP was carried in respiratory medicine department of four hospitals from July 1, 2017 to August 31, 2018 (Changhai Hospital, Shanghai First People’s Hospital, Baoshan Branch of Shanghai First People’s Hospital, and Baoshan Integrated Traditional Chinese and Western Medicine Hospital). According to the time of tracheoscopy intervention treatment, they were divided into 3 groups: 127 patients treated with tracheoscopy intervention during the initial treatment period (within 72 h after obtaining imaging diagnosis) were included in an early intervention group, 158 patients treated with tracheoscopy intervention 72 h after obtaining imaging diagnosis were included in a medium-term intervention group, and 134 patients treated without tracheoscopy intervention were included in a non-intervention group. The total efficiency of treatment, improvement of clinical symptoms, imaging absorption, serum inflammation index level, sputum culture positive rate, change rate, efficiency after drug change, hospital stay and hospitalization cost were compared among three groups.ResultsThe total efficiency of treatment in the early intervention group was higher than that of the medium-term intervention group and the non-intervention group, with statistically significant difference (P<0.05), and the time of normality of body temperature, the time of disappearance of strong sputum and cough in the early intervention group, the absorption time of chest X-rays were shorter than that of the medium-term intervention group and the non-intervention group, and the difference was statistically significant (P<0.05); peripheral blood hemoglobin, serum calcitonin and hypersensitive C reactive protein levels were lower than those in the medium-term intervention group and the non-intervention group, with statistically significant differences (P<0.05), and the sputum-positive and drug-change rates in the early intervention group and the medium-term intervention group were higher than those in the non-intervention group, and the difference was statistically significant (P<0.05); the duration of hospital stay in the early intervention group was shorter than that of the medium-term intervention group and the non-intervention group, and the cost of hospitalization was less than that of the medium-term intervention group and the non-intervention group, and the difference was statistically significant (P<0.05).ConclusionTracheoscopy intervention treatment in the initial period of CAP not only significantly improves the efficacy, but also significantly reduces treatment costs and length of hospitalization, hence it is worth clinical promotion.
ObjectiveTo analyze the clinical features of Legionella-associated cavitary pneumonia, and to explore the diagnosis, treatment planning, and clinical management of patients.MethodsThe data of a patient with severe Legionella-associated cavitary pneumonia were collected and analyzed. Databases including PubMed, Ovid, Wanfang, VIP and Chinese National Knowledge Infrastructure were searched for pertinent literatures, using the keyword "Legionella, lung abscess or cavitary pneumonia" in Chinese and English from Jan. 1990 to Jun. 2019. The related literature was reviewed.ResultsA 60-year-old male patient was admitted to hospital because of fever, cough, and expectoration for five days. On presentation, his temperature was 38.3 °C, and pulmonary auscultation revealed rales on the left side of the lungs. Culture of lower airway secretions obtained by bronchoscopy revealed Legionella pneumophila infection, and serotype 6. Chest computerized tomography showed a consolidation in the left lung and an abscess in the left upper lobe. The patient was discharged from the hospital after three months of anti-Legionella treatment (Mosfloxacin, Azithromycin, etc.). Fifteen manuscripts, including 18 cases, were retrieved from databases. With the addition of our case, a total of 19 cases were analyzed in detail. There were 15 males and four females, aged from 4 months to 73 years old. Most of them (14/19, 73.7%) were accompanied by multiple underlying diseases. Initial empiric antimicrobial therapy failed in 15 (78.9%) cases, and 7 (36.8%) patients required combination therapy. The courses of antimicrobial treatment were from 3 to 49 weeks. All except one patient were fully recovered and discharged from hospital.ConclusionsLegionella pneumonia with pulmonary abscess or cavity is rare and often presents with fever. Pulmonary imaging shows infiltration in the initial, but can be free of cavities or abscesses. Most patients have basic diseases. Severe patients often need to be treated in combination with antibiotics for long periods of time.
Objective To investigate the therapeutic effect of dexamethasone on children with severe community acquired pneumonia ( CAP) . Methods 120 children with severe CAP admitted from January 2009 to June 2011 were recruited in the study. The patients were randomly divided into a dexamethasone group ( n = 62) and a control group ( n = 58) . The patients in the dexamethasone group received additional dexamethasone intravenous injection for 3 days ( 0. 2-0. 4 mg· kg- 1 · d- 1 , qd) on the basic treatment of the control group. Length of hospital stay, serum C reactive protein ( CRP) concentration on 4th day after admission, overall efficacy, mortality, incidence of adverse events during treatment were compared between the two groups. Results Median length hospital stay was 8 days in the dexamethasone group compared with 9 days in the control group without significant difference ( P gt;0. 05) . The serumCRP concentration on 4th day was lower in the dexamethasone group than that in the control group [ ( 23. 4 ±5. 6) mmol /L vs. ( 41. 3 ±6. 2) mmol /L, P lt;0. 05] . The overall efficacy was higher in the dexamethasone group than that in the control group ( 88. 7% vs. 74. 1% , P lt; 0. 05) . The in-hospital mortality and incidence of severe adverse events were not significantly different between the two groups ( P gt; 0. 05) . Conclusions Dexamethasone treatment is associated with a significant attenuation in systematic inflammatory response, but does not decrease mortality in hospitalized children with severe CAP.
ObjectiveTo investigate the role of dynamic monitoring procalcitonin (PCT) in the comprehensive evaluation during the diagnosis and treatment of community acquired pneumonia (CAP). MethodsFour hundred and sixty-eight patients with CAP were randomly assigned to a PCT-guided group (the research group) and a standard guideline group (the control group). The clinical symptoms,CURB-65 grade,blood leucocyte count and classification,and C-reactive protein (CRP)were compared between two groups. The PCT-guided application time of antibiotics,the hospitalization time,chest CT examination rate,the cure or the improvement rate were also estimated and commpared. ResultsThe hospitalization time [(9.6±1.7)days vs. (10.9±1.6)days],hospitalization cost [(6 957.11±1 009.46) yuan vs. (8 011.35±1 049.77) yuan],chest CT examination rate (56.96% vs. 89.40%),the application time of antibiotics [(16.5±2.3)days vs. (20.0±1.2)days],and the rate of required antibiotics upgrade (6.96% vs. 11.06%) in the research group were all significantly lower than the control group (P<0.05). There was no significant difference between two groups in the ratio of the adverse reaction of antibiotics (14.78% vs. 15.20%),the rate of transfer into ICU (2.61% vs. 3.69%) or the mortality (1.74% vs. 2.30%)(P>0.05). ConclusionOn the basis of CAP guidelines,the dynamic monitoring of PCT may shorten the time of antibiotic use and the hospitalization,reduce the cost of hospitalization and the rate of chest CT scan in patients with CAP.
ObjiectiveTo obtain reliable evidence of diagnosis and treatment through evaluating the validity of pneumonia severity index (PSI), CURB-65 and acute physiology and chronic health evaluationⅡ(APACHEⅡ) scores in predicting risk stratification, severity evaluation and prognosis in elderly community-acquired pneumonia (CAP) patients.MethodsClinical and demographic data were collected and retrospectively analyzed in 125 in-hospital patients with CAP admitted in Shanghai Dahua Hospital from January 2012 to April 2015. The severity of pneumonia was calculated with PSI, CURB-65 and APACHEⅡgroups during 1 to 3 days after admission. Mortality and intensive care unit (ICU) admission rates were evaluated among patients in each scores and was categorized into three classes, namely mild, moderate and severe groups during 1 to 3 days after admission. Mortality and ICU admission rates were evaluated among patients in each severity level. Through evaluating the sensitivity, specificity, the predicting values and the area under receiver operating characteristic (ROC) curve (AUC) among PSI, CURB-65 and APACHEⅡ, the validity and consistency of these three scoring systems were assessed.ResultsUsing PSI, CURB-65 and APACHEⅡ scoring systems, the patients were categorized into mild severity (48.8%, 64.0% and 52.8%, respectively), moderate severity (37.6%, 23.2% and 32.0%, respectively) and severe severity (13.6%, 12.8% and 15.2%, respectively). In PSI, CURB-65 and APACHEⅡ systems, the mortality in high risk groups was 41.3%, 62.5% and 47.4%, respectively; The ICU-admission rate in high risk groups was 88.3%, 100.0% and 94.7%, respectively. The sensitivity of PSI, CURB-65 and APACHEⅡ was 50.0%, 71.4% and 64.3% in predicting mortality, and was 46.8%, 50.0% and 59.3% in predicting ICU-admission, respectively. PSI, CURB-65 and APACHEⅡ showed similar specificity (approximately 90%) in predicting mortality and ICU admission. ROC was conducted to evaluate the sensitivity of PSI, APACHEⅡ and CURB-65 in predicting mortality and ICU admission. The AUC had no significant difference among these three scoring systems. The AUC of PSI, CURB-65 and APACHEⅡwas 0.893, 0.871, 0.880, respectively for predicting mortality, and was 0.949, 0.837, 0.949, respectively for predicting ICU admission. There was no significant difference among these three scoring in predicting mortality and ICU admission (all P>0.05).ConclusionsPSI, CURB-65 and APACHEⅡ performed similarly and achieved high predictive values in elderly patients with CAP. The three scoring systems are consistent in predicting mortality risk in elderly CAP patients. The CURB-65 is more sensitive in predicting the risk of death, and more early in identifing patients with high risk of death. The APACHEⅡ is more sensitive in predicting the risk of ICU admission, and has good value in identifying severe patients and choosing the right treatment sites.
ObjectiveTo explore the correlation of serum neutrophil gelatinase-associated lipocalin (sNGAL) with inflammatory response in patients with community-acquired pneumonia (CAP) and assess the diagnostic value of sNGAL for severe CAP (SCAP).MethodsFrom January 2018 to June 2019, a total of 85 patients with CAP were enrolled in this study. Age, length of hospital stay, the levels of serum creatinine, blood urea nitrogen, white blood cell count,C-reactive protein (CRP), interleukin-6 (IL-6), and procalcitonin, and CURB-65 score were compared between patients with SCAP (n=34) and patients without SCAP (n=51). The correlations of sNGAL with serum creatinine, blood urea nitrogen, white blood cell count, CRP, IL-6, procalcitonin, and CURB-65 score were assessed with Spearman’s correlation analysis. The area under the receiver operating characteristic (ROC) curve for sNGAL diagnosing SCAP was examined. ResultsCompared with patients without SCAP, SCAP patients demonstrated older age, longer hospital stay, higher serum CRP and IL-6 concentritions, and higher CURB-65 score (P<0.05). The Spearman’s correlation test showed that sNGAL was positively correlated with serum CRP, IL-6, PCT and CURB-65 score (rs=0.472, 0.504, 0.388, and 0.405, respectively; P<0.01). According to ROC analysis, the area under curve of sNGAL for diagnosing SCAP were 0.816, with a sensitivity of 76.56% and a specificity of 74.4% when the cut-off value was 171.0 ng/mL.ConclusionssNGAL concentration is positively correlated with the serverity of CAP. It can be regarded as a reliable indicator for diagnosis of SCAP in patients with CAP.
ObjectivesTo explore the clinical characteristics and risk factors for 30-day mortality of community-acquired pneumonia (CAP) patients with chronic obstructive pulmonary disease (COPD).MethodsThis was a multicentre, retrospective study. Data of patients hospitalized with CAP from four tertiary hospitals in Beijing, Shandong and Yunnan from January 1, 2013 to December 31, 2015 were reviewed. Patients with (COPD-CAP) and without (non COPD-CAP) COPD were compared, including demographic and clinical features, treatment and outcomes. Univariate analysis and multivariate Logistic regression analysis were performed to identify risk factors for 30-day mortality in COPD-CAP patients.ResultsThree thousand three hundred and sixty-six CAP patients were entered into final analysis, COPD-CAP accounted for 12.9% (435/3 366). Compared to non COPD-CAP patients, COPD-CAP patients were more male and more frequent with CURB-65 score 2 and pneumonia severity index (PSI) risk class Ⅲ to Ⅴ. Pseudomonas aeruginosa was the most common etiology and more common in COPD-CAP patients than non COPD-CAP patients. Though the proportion of respiratory failure and heart failure were higher in COPD-CAP patients, there was no significant difference in the 30-day mortality. The 30-day mortality of COPD-CAP patients was 5.7% (25/435). Logistic regression analysis confirmed aspiration (OR 9.505, 95%CI 1.483 - 60.983, P=0.018), blood procalcitonin ≥2.0 ng/mL (OR 5.934, 95%CI 1.162 - 30.304, P=0.032) and PSI risk class (OR 2.533, 95%CI 1.156 - 5.547, P=0.020) were independent risk factors for 30-day mortality in COPD-CAP patients.ConclusionsCOPD-CAP patients present specific characteristics. Besides PSI risk class, clinicians should pay high attention to the aspiration and blood procalcitonin, which could increase the 30-day mortality in COPD-CAP patients.
