Meta-analysis and trial sequential analysis of Tanreqing Injection in treatment of severe pneumonia in elderly
This study aimed to systematically evaluate the effectiveness and safety of Tanreqing Injection in the treatment of severe pneumonia in the elderly.Eighteen randomized controlled trials(RCTs)involving 1 457 elderly patients with severe pneumonia were included in the study after conducting searches in both Chinese and English databases as well as clinical trial registration platforms.The quality of the included studies was assessed using the Cochrane risk of bias assessment tool.Meta-analysis were conducted using RevMan 5.4 and Stata 17 software,and trial sequential analysis(TSA)was performed using TSA 0.9.5.10 beta software.Meta-analysis results showed that compared with conventional western medicine treatment,Tanreqing Injection+conventional western medical significantly improved the clinical effectiveness in elderly patients with severe pneumonia(RR=1.26,95％CI[1.20,1.32],P＜0.000 01),arterial oxygen partial pressure(SMD=6.23,95％CI[3.29,9.18],P＜0.000 1),oxygenation index(SMD=11.72,95％CI[4.41,19.04],P=0.002),reduce procalcitonin(SMD=-6.16,95％CI[-8.10,-4.21],P＜0.000 01),C-reactive protein(SMD=-8.50,95％CI[-11.05,-5.96],P＜0.000 01),white blood cell count(SMD=-4.56,95％CI[-5.73,-3.39],P＜0.000 01),and shortened the duration of fever(SMD=-3.12,95％CI[-4.61,-1.63],P＜0.000 1),cough(SMD=-4.84,95％CI[-6.90,-2.79],P＜0.000 01),lung rales(SMD=-0.99,95％CI[-1.54,-0.44],P=0.000 4),and mechanical ventilation time(SMD=-3.26,95％CI[-5.03,-1.50],P=0.000 3),increase CD4+T-cell levels(SMD=6.73,95％CI[5.23,8.23],P＜0.000 01)and CD8+T-cell levels(SMD=7.47,95％CI[5.32,9.61],P＜0.000 01)with no significant adverse reactions.TSA confirmed the stability and reliability of the results related to clinical effectiveness.This study suggests that Tanreqing Injection,as a Chinese medicinal preparation,has a significant therapeutic effect and good safety profile in the treatment of severe pneumonia in elderly patients.Due to the limited quality of the included studies,high-quality RCT is still needed to provide evidence support for the above conclusions.
