目的:探讨血清降钙素原(procalcitonin,PCT)水平对系统性红斑狼疮(systemic lupus erythematosus,SLE)患者病情活动和细菌性感染的鉴别诊断作用。方法前瞻性对2010年4月至2013年4月发热(体温≥38.3℃)或符合全身炎性反应综合征(或脓毒症)标准的 SLE 患者行 PCT、C-反应蛋白(C-reactive protein,CRP)、补体3(C3)及病原学等检测及比较;依据 SLE 疾病活动指数(SLE diease activity index,SLEDAI)及临床感染证据等,分为细菌性血流感染,细菌性局部感染、SLE 病情活动3组。另外纳入缓解期无发热 SLE 患者作为对照组。血流感染组在使用抗感染药物1周后再次测定血清 PCT、CRP 水平。结果血流感染组22例,局部感染组28例,SLE 活动组27例,对照组20例。血流感染组 PCT [11.00(8.80,16.84)μg/L]和 CRP [78.86(62.04,89.37)mg/L]明显高于局部感染组[2.22(1.65,2.56)μg/L 和23.48(20.20,27.55) mg/L]、活动组[0.19(0.16,0.22)μg/L 和19.34(15.98,19.78)mg/L]和对照组[0.11(0.07,0.12)μg/L 和4.30(3.83,4.98)mg/L],差异均有统计学意义(P =0.000);局部感染组 PCT 较活动组和对照组增高,差异有统计学意义(P =0.034, P =0.016);PCT 浓度在 SLE 对照组和活动组差异无显著性意义(P =0.950)。革兰阴性杆菌血流感染的 PCT 值[14.10(10.13,20.63)μg/L]明显高于革兰阳性菌[1.00(0.70,9.44)μg/L,Z =-2.900,P =0.004]。动态监测血流感染组发现,在抗菌药物治疗1周后血清 PCT 可快速下降,由11.00(8.80,16.84)μg/L 降至0.38(0.28,0.48)μg/L,P =0.000。结论 PCT 在 SLE 缓解期和病情活动时基本正常,在 SLE 合并细菌性血流感染时显著升高;革兰阴性杆菌血流感染的 PCT 值较革兰阳性菌更高;提示 PCT 有可能作为 SLE 细菌感染的一项快速鉴别指标,与 SLE 细菌感染的严重程度相关。
目的:探討血清降鈣素原(procalcitonin,PCT)水平對繫統性紅斑狼瘡(systemic lupus erythematosus,SLE)患者病情活動和細菌性感染的鑒彆診斷作用。方法前瞻性對2010年4月至2013年4月髮熱(體溫≥38.3℃)或符閤全身炎性反應綜閤徵(或膿毒癥)標準的 SLE 患者行 PCT、C-反應蛋白(C-reactive protein,CRP)、補體3(C3)及病原學等檢測及比較;依據 SLE 疾病活動指數(SLE diease activity index,SLEDAI)及臨床感染證據等,分為細菌性血流感染,細菌性跼部感染、SLE 病情活動3組。另外納入緩解期無髮熱 SLE 患者作為對照組。血流感染組在使用抗感染藥物1週後再次測定血清 PCT、CRP 水平。結果血流感染組22例,跼部感染組28例,SLE 活動組27例,對照組20例。血流感染組 PCT [11.00(8.80,16.84)μg/L]和 CRP [78.86(62.04,89.37)mg/L]明顯高于跼部感染組[2.22(1.65,2.56)μg/L 和23.48(20.20,27.55) mg/L]、活動組[0.19(0.16,0.22)μg/L 和19.34(15.98,19.78)mg/L]和對照組[0.11(0.07,0.12)μg/L 和4.30(3.83,4.98)mg/L],差異均有統計學意義(P =0.000);跼部感染組 PCT 較活動組和對照組增高,差異有統計學意義(P =0.034, P =0.016);PCT 濃度在 SLE 對照組和活動組差異無顯著性意義(P =0.950)。革蘭陰性桿菌血流感染的 PCT 值[14.10(10.13,20.63)μg/L]明顯高于革蘭暘性菌[1.00(0.70,9.44)μg/L,Z =-2.900,P =0.004]。動態鑑測血流感染組髮現,在抗菌藥物治療1週後血清 PCT 可快速下降,由11.00(8.80,16.84)μg/L 降至0.38(0.28,0.48)μg/L,P =0.000。結論 PCT 在 SLE 緩解期和病情活動時基本正常,在 SLE 閤併細菌性血流感染時顯著升高;革蘭陰性桿菌血流感染的 PCT 值較革蘭暘性菌更高;提示 PCT 有可能作為 SLE 細菌感染的一項快速鑒彆指標,與 SLE 細菌感染的嚴重程度相關。

Objective To evaluate whether the concentration of serum procalcitonin(PCT)will help to distinguish bacterial infection from disease activity in febrile systemic lupus erythematosus (SLE )patients. Methods Hospitalized SLE patients presented with fever (T ≥ 38.3℃),who were conformed to be systemic inflammatory response syndrome(SIRS)or sepsis,were prospectively enrolled into this study and were divided into three groups according to their SLE disease activity index(SLEDAI)and the etiology:bloodstream infection group(group I),local bacterial infection(group II)and active lupus(group III). Patients at remission who were referred to outpatient department were enrolled as controls.PCT and C-reactive protein (CRP)were measured before antibiotics usage and after treated for one week.These parameters were measured at the same time with erythrocyte sedimentation rate(ESR),white cell count (WBC)compliment 3(C3).Results There were 22 cases in group I,28 cases in group II,27 cases in group III,and 20 cases in control group.The serum PCT and CRP levels were significantly higher in group I [11.00(8.80,16.84)μg/L,78.86(62.04,89.37)mg/L]than that in group II [2.22(1.65,2.56)μg/L,23.48(20.20,27.55)mg /L,P =0.000],group III [0.19(0.16,0.22)μg/L,19.34(15.98, 19.78)mg/L,P =0.000]and control group [0.11(0.07,0.12)μg/L,4.30(3.83,4.98)mg/L,P =0.000].While there was no significant difference in serum PCT level between group III and control group (P =0.950).Serum PCT levels in Gram-Negative bacillus infections [14.10(10.13,20.63)μg/L ]were significantly higher than in Gram-Positive bacterium infections [1.00(0.70,9.44)μg/L,Z =-2.900, P =0.004;]in group I.After a week’s therapy of antibiotics,PCT level [0.38(0.28,0.48)μg/L]was significantly lower than that of the preceding level [11.00(8.80,16.84)μg/L]in group I(P =0.000). Conclusions PCT is generally at the normal range both in active and remission lupus patients,but it is significantly elevated in SLE patients with bloodstream infection,and it returns to normal after infections are under control.PCT levels in Gram-Negative bacillus infections are significantly higher than those in Gram-Positive bacterium infections patients.PCT may be a useful marker in differentiating the causes of fever in SLE patients.Furthermore,the PCT level is correlated with the severity of infection.
