【摘要】 目的探讨慢性丙型肝炎患者血清白介素-8(IL-8)水平与丙型肝炎病毒(HCV)感染、基因型及抗病毒治疗的关系。方法对74例慢性丙型肝炎患者应用基因芯片法进行基因型检测,应用双抗体夹心ABC-ELISA法检测患者血清IL-8。比较不同基因型患者之间IL-8水平的差别,观察了抗病毒治疗12周后IL-8水平的变化。结果慢性丙型肝炎患者及健康对照组血清IL-8水平分别为(42.95±50.00)pg/mL及(11.06±1.39)pg/mL(P<0.01);基因1b型慢丙肝患者(46例)及基因2a型患者(28例)IL-8水平分别为(52.72±60.67)pg/mL及(26.93±13.97)pg/mL(P<0.05)。抗病毒治疗后HCV RNA转阴者,其IL-8水平由(41.20±25.89)pg/mL降至(23.89±10.59)pg/mL(P<0.01)。结论慢丙肝患者血清IL-8水平较健康对照组明显升高,且以感染HCV基因1b型者更明显。抗病毒治疗HCV RNA阴转后,其IL-8水平明显回降。更多还原

【Abstract】 Objective To study the relationship of expression level of serum interleukin-8(IL-8) and HCV genotypes in patients with chronic hepatitis C and observe the change of serum IL-8 level after antivirus treatment.Methods HCV genotypes were determined using DNA chip assay in 74 chronic hepatitis C patients.Serum IL-8 of these patients was determined using bi-antibody sandwich ABC-ELISA assay.Levels of IL-8 in chronic hepatitis C patients with different genotypes were compared.The change of IL-8 level after 12 weeks of antivirus treatment was observed.Results Levels of serum IL-8 in chronic hepatitis C patients and healthy controls were(42.95±50.00)pg/mL and(11.06±1.39)pg/mL,respectively(P<0.01),and in patients infected with genotype 1b and genotype 2a were(52.72±60.67)pg/mL and(26.93±13.97)pg/mL,respectively(P<0.05).After 12 weeks of antivirus treatment,the serum IL-8 level in patients with undetectable HCV RNA decreased from(41.20±25.89)pg/mL to(23.89±10.59)pg/mL(P<0.01).Conclusions The serum level of IL-8 in patients with chronic hepatitis C significantly increases compared with that in healthy controls.The IL-8 level in patients with genotype 1b is higher than that in patients with genotype 2a.The IL-8 level in patients with undetectable HCV RNA significantly decreases after antivirus treatment.更多还原
