目的了解H IV感染者CD4细胞计数、结核菌素(PPD)反应及两者的相互影响情况。方法抽取2032例H IV感染者进行CD4细胞计数和5U的PPD试验。结果CD4细胞计数随患者年龄的增加而明显下降,CD4计数小于等于200个/mm3者占25%,大于等于500个/mm3者21.4%,位于两者之间者53.6%;PPD反应阳性率14.7%,随年龄的增加而呈上升趋势;CD4细胞计数与PPD反应呈负相关,但无统计学意义(P>0.05)。结论H IV感染者中PPD反应阳性率较低;PPD反应与CD4细胞计数呈负相关但无统计学意义(P>0.05)。
Objective To understand the CD4 count, tuberculin (PPD) response and the interaction between them in patients with H IV infection. Methods Totally 2032 H IV infected patients were enrolled in CD4 cell count and 5U PPD test. Results The CD4 cell count decreased significantly with the increase of the patient’s age. The CD4 count of less than 200 / mm3 accounted for 25%, more than 500 / mm3 21.4%, 53.6% between the two; PPD positive rate 14.7 %, Rising with age; CD4 cell count was negatively correlated with PPD but not statistically significant (P> 0.05). Conclusions The positive rate of PPD in patients with H IV infection is low, while the PPD reaction is negatively correlated with CD4 count (P> 0.05).
