摘要:

目的了解慢性阻塞性肺疾病(COPD)稳定期患者血清白细胞介素-8(IL-8)、高敏C反应蛋白(hsCRP)水平,探讨其影响因素及其临床意义。方法用酶联免疫吸附测定法(ELISA)同步检测54例中、重度COPD稳定期患者和20例健康对照者血清IL-8、hsCRP水平,分析其相关因素。结果COPD患者血清IL-8、hsCRP水平显著高于健康对照组(P均<0.01);其中COPD吸烟组血清IL-8、hsCRP水平显著高于COPD非吸烟组血清IL-8(P<0.01)、hsCRP(P<0.05)水平;重度COPD患者血清IL-8、hsCRP水平明显高于中度COPD患者(P均<0.01)。相关分析表明,血清IL-8、hsCRP与吸烟年包、SGRQ生活质量症状、社会影响及总评分呈显著正相关(P均<0.01),与FEV1呈负相关(P<0.05)。此外,COPD患者血清hsCRP还与生活质量活动能力评分正相关(P<0.01),与6分钟步行试验(6MWT)呈显著负相关(P<0.05),而且血清IL-8和hsCRP二者之间呈显著正相关(P<0.001)。结论中重度COPD稳定期患者血清IL-8、hsCRP水平均升高,吸烟可能是血清IL-8、hsCRP水平升高的一个影响因素。此外,气流受限越重,生活质量越差,血清IL-8、hsCRP水平越高,提示COPD稳定期患者不仅存在气道炎症也存在全身炎症反应,气流受限程度可以影响周身炎性反应及生活质量。

Abstract:

Objective To understand the serum interleukin-8 (IL-8),high
      sensitive C-reactive proteins (hsCRP)levels,their correlation factors and
      clinical significance in patients with stable chronic obstructive
      pulmonary disease (COPD). Methods The serum IL-8,hsCRP levels in 54 stable
      COPD patients and 20 healthy controls were measured by enzyme-linked
      immunosorbent assay(ELISA).Correlation factors of serum IL-8,hsCRP levels
      were analyzed. Results The serum IL-8,hsCRP levels in COPD patients were
      significantly higher than those in the healthy controls(P < 0.01). The
      serum IL-8,hsCRP levels in smoking COPD patients were significantly higher
      than that in the non- smoking controls(P < 0.01 and P < 0.05
      respectively). The serum IL-8,hsCRP levels in severe COPD patients were
      significantly higher than those in the moderate patients(P < 0.01);Linear
      correlation analysis showed that the levels of serum IL-8,hsCRP were
      significantly positive associated with smoking pack-years,symptom
      scores,impact scores and total scores of quality of life with St.
      George,S Questionnaire(SGRQ) (P < 0.01).There was a negative correlation
      between the serum IL-8,hsCRP levels and forced expiratory volume in one
      second(FEV1)(P < 0.05). Moreover,the serum hsCRP level was positive
      associated with activity scores of quality of life(P < 0.01)and negative
      associated with six-minutes walking distance(6MWD)(P < 0.05). There was a
      positive correlation between the serum IL-8 level and serum hsCRP leve(lP
      < 0.001). Conclusion The serum IL-8,hsCRP levels in stable COPD patients
      were higher. Smoking maybe is an factor which affects serum IL-8,hsCRP
      levels. The more severe is airflow limitation and the worst is quality of
      life,the higher the serum IL-8,hsCRP levels are. It showed that not only
      is airway inflammation but also systemic inflammation could coexist in
      stable COPD patients. Airflow limitation can af- fect systemic
      inflammation and quality of life.
