Objective To study the early diagnostic value of C-reactive protein(CRP) and procalcitonin(PCT) in urinary tract infection(UTI) in patients with benign prostatic hyperplasia (BPH).Methods A prospective study was performed on 77 patients with suspected UTI with BPH in our hospital.According to the urine bacterial culture results,77 cases were divided into infection group(n=49) and control group(n=28).The sensitivity and specificity of CRP and PCT in the diagnosis of UTI patients with BPH,and their correlation were evaluated.Results There was significant difference in CRP and PCT levels between two groups(P0.05),具有可比性。本研究经医院医学伦理委员会批准,患者及家属知情同意,符合医学伦理学要求。排除标准:近7 d使用过抗生素患者;有泌尿系统外感染性疾病仍处于治疗中的患者。 1.2方法
所有入选患者在未用抗生素前立即送检血常规、CRP和PCT,并在24 h内完成尿液细菌培养。记录患者一般资料,随访半个月,补充尿培养结果等。CRP检测采用TBA120全自动生化分析仪;PCT采用化学发光免疫夹心法,在迈格鲁米化学发光测定仪上检测。
1.3统计学方法
采用IBM SPSS 22.0统计软件,计量资料以均数±标准差(x±s)表示,采用t检验;计数资料以率表示,采用χ2检验,相关性分析采用Pearson相关分析;ROC曲线分析敏感度及特异度,以P0.05)
2.2两组患者CRP与PCT的相关性分析
感染组患者CRP与PCT具有相关性(r=0.509,P0.05),提示血清CRP和PCT在BPH合并UTI的早期诊断中具有重要临床意义,可为该类疾病的临床早期诊断提供相关的判定依据,有利于该疾病的及时治疗,改善患者预后。
ROC曲线分析CRP、PCT诊断BPH合并UTI,在各自最优界点时,AUC值分别为0.805和0.859,敏感度分别为89.7%、87.6%,特异度分别为60.7%、71.4%。PCT的特异度较CRP有显著提高,两者敏感度相近。若将两者综合分析,可提高早期诊断BPH合并UTI的准确性,为临床治疗决策提供参考。
