Based on review and practice of literature search of clinical economic evaluation, We have discussed the source and search strategy of literatures of clinical economic evaluation. A sample on antibiotics in the treatment of community-acquired pneumonia was shown concurrently.
Objective To detect the levels and study the significance of serum soluble intercellular adhension molecule-1(sVCAM-1),soluble vascular cell adhension molecule-1 (sVCAM-1) in patients with community-acquired pneumonia(CAP).Methods sICAM-1 and sVCAM-1 were detected by enzymelinked immunosorbent assy（ELISA）in 25 patients with CAP before and after treatment as well as in 10 healthy controls.Results Before treatment, the levels of serum sICAM-1 and sVCAM-1 in the patients with CAP[（2.658 4±0.259 7）ng/mL,(2.680 9±0.255 4）ng/mL)] were significantly higher than those in controls[(2.472 8±0.077 6)ng/mL,（2.426 3±0.307 2)ng/mL](Plt;0.01,Plt;0.05). After treatment, the levels of serum sICAM-1, sVCAM-1 significantly decreased [(2.518 3±0.205 2)ng/mL,(2.523 0±0.279 4)ng/mL](Plt;0.01,Plt;0.01) and were not different from those in controls（Pgt;0.05）.The levels of sICAM-1 were positively associated with neutrophil counts（r=0.602，Plt;0.001）rather than the levels of sVCAM-1（r＝0.036，Pgt;0.05）.Conclusion The changes of sICAM-1 and sVCAM-1 before and after treatment are predictive to the prognosis in patients with CAP.
社区获得性肺炎( CAP) 是严重威胁人类健康的常见疾病之一, 但在其诊断和治疗仍存在相当大的差异。临床路径( clinical pathway, CP) 是一种新的临床诊疗规范管理方式,近年来开始应用于CAP 的临床诊治, 陆续有协会组织开始制定关于CAP 的临床路径, 并应用于临床。
Objective To observe the gamma-glutamyltransferase ( GGT) activity and total antioxidant capacity ( T-AOC) in serum and platelet during the course of community-acquired pneumonia ( CAP) . Methods Ninety cases of hospitalized CAP were recruited from the respiratory wards in the Affiliated Hospital of XuzhouMedical College fromSeptember 2010 to September 2011, and 30 healthy cases who underwent physical examination in the same hospital were enrolled as control. GGT activity and T-AOC were compared between the CAP patients and the control subjects, and also between the CAP patients who developed reactive thrombocytosis ( platelet count gt;300 ×109 /L) and those without thrombocytosis ( platelet count ≤300 ×109 /L) . Results Compared with the control subjects, serumand platelet GGT activity of the CAP patients were significantly higher [ ( 45. 6 ±25. 4) U/L vs. ( 17. 9 ±3. 7 ) U/L, ( 179. 9 ±41. 3) mU/109plt vs. ( 49. 5 ±8. 0) mU/109plt, P lt; 0. 05] , serum T-AOC at admission was significantly lower [ ( 12. 6 ±1. 6) U/mL vs. ( 17. 7 ±2. 1) U/mL, P lt; 0. 05] , and platelet T-AOC at admission was significantly higher [ ( 61. 6 ±18. 3) mU/109plt vs. ( 48. 6 ±9. 9) mU/109 plt, P lt; 0. 05] . Platelet T-AOC of the CAP patients at discharge was significantly lower than that of the CAP patients at admission and the control subjects. Compared with the CAP patients without thrombocytosis, serum T-AOC and serum GGT activity of the CAP patients who developed reactive thrombocytosis were significantly higher( P lt;0. 05) , and platelet T-AOC and platelet GGT activity were both significantly lower ( P lt; 0. 05) . There were negative correlations of the platelet count with platelet T-AOC and GGT activity in the CAP patietns( r = - 0. 316,P =0.003; r = - 0. 318, P =0. 002) . Conclusions There is a correlation between the oxidative stress and the platelet function in the inflammatory process of CAP. There might be an indicative role of platelets in resolving the inflammatory process and in maintaining the oxidative-antioxidative balance.
Objective To evaluate and select essential medicine for community-acquired pneumonia (CAP) using evidence-based methods based on the burden of disease. Methods By means of the approaches, criteria, and workflow set up in the second article of this series, we referred to the recommendations of evidence-based or authority guidelines from inside and outside China, collected relevant evidence from domestic clinical studies, and recommended essential medicine based on evidence-based evaluation. Data were analyzed by Review Manager (RevMan) 5.1 and GRADE profiler 3.6 to evaluate quality of evidence. Results (1) Eleven guidelines were included (nine foreign guidelines, two domestic guidelines; nine based on evidence, two based on expert consensus). For CAP, amoxicillin amp; clavulanate potassium had efficiencies of 77.1% and an incidence of 18.8% as to adverse reaction that mainly included gastrointestinal reaction, skin rashes, etc. Piperacillin/tazobactam had an efficiency of 92.1% and a bacterial clearance rate of 88.9%. Cefuroxime had an efficiency of 89% and a bacterial clearance rate of 85.5%. There was no statistical significance between azithromycin and cefuroxime for CAP (RR=0.98, 95%CI 0.9 to 1.06); however, azithromycin was superior to cefuroxime in shortening fever-relief time (MD=–0.98, 95%CI –1.24 to –0.55) and cough-relief time (MD=–1.36, 95%CI –1.94 to –0.78). Efficiencies of ceftriaxone, cefotaxime, moxifloxacin and lavofloxacin were all more than 80% and among the three, moxifloxacin was the most efficient (RR=1.08, 95%CI 1.02 to 1.13, P=0.004). Meropenem had an efficiency of 90%, a bacterial clearance rate of 83.3% and an incidence of 3.33% as to adverse reaction that mainly included diarrhea. Conclusion (1) We offer a b recommendation for antibiotics such as amoxicillin, amoxicillin amp; clavulanate potassium, ampicillin/sulbactam, piperacillin/tazobactam, doxycycline, azithromycin, clarithromycin, cefuroxim, ceftriaxone, cefotaxime, lavofloxacin, moxifloxacin, ertapenem, meropenem, imipenem and vancocin. (2) We offer a weak recommendation for penicillin G, ciprofloxacin and erythromycin. (3) We propose that doctor should choose optimal antibiotics based on commonly-seen pathogenic bacteria that cause CAP, local criteria of antibiotic susceptibility, severity of CAP, and risk factors of patients.
