Abstract:
Objective To analyze the differentiation status of CTL and to evaluate its clinical val-ue in patients with HIV/HCV coinfection .Methods Twenty-eight patients with HIV/HCV coinfection and twelve patients with single HCV infection were enrolled in this study .The technique of Fibro-Scan was used to evaluate liver fibrosis .The viral load of HCV was detected by real-time quantitative PCR .Flow cytometry analysis was performed to measure the differentiation status of CTL .Results Both of the levels of alanine transaminase ( ALT) and alkaline phosphatase ( ALP) in patients with HIV/HCV coinfection were signifi-cantly higher than those in patients with single HCV infection [(53.7464±48.1180) U/L vs (27.4750± 13.9850) U/L, P=0.012;(24.5071±8.1940) g/L vs (16.9667±7.1890) g/L, P=0.009].The liver stiffness of patients with HIV/HCV coinfection was higher than that of patients with single HIV infection [(5.9500, 5.8250) Kpa vs (5.1500, 1.0500) Kpa, P=0.117].Compared with the patients with single HCV infection, the patients with HIV/HCV coinfection showed higher viral loads of HCV [( 6.4768, 5.3434) lg copy/ml vs (2.6815, 1.6990) lg copy/ml, P=0.012], but lower clearance rate of HCV [32.14%vs 75%, P=0.032].Compared with the patients with single HCV infection , the patients with HIV/HCV coinfection showed lower percentages of CD 27+CD28+CTL [(28.265±15.095)%vs (18.068±10.263)%, P=0.017), but higher percentages of CD27+/-CD28+CTL [(62.449 ±14.561)% vs (71.111±12.681)%, P=0.066].A trend toward negative correlation was observed between the percent -age of CD27+CD28+CTL and the degree of liver stiffness (r=-0.310, P=0.058).Conclusion HIV in-fection could accelerate the progression of liver disease in patients with HIV /HCV coinfection by affecting the differentiation of CTL .
