Abstract:
Objective To observe the expression and significance of helper T cells 9(Th9),helper T cells 22(Th22)and their ef-fector factors in peripheral blood of drug-induced liver injury(DILI).Methods Fifty-six patients with DILI were selected as DILI group and 15healthy volunteers as healthy control group.The DILI group was divided into four groups:mild liver injury group(15 cases),moderate liver injury group(15 cases),severe liver injury group(15 cases)and acute liver failure group(11 cases).Meanwhile,serum liver function,peripheral blood Th9 and Th22,serum interleukin-9(IL-9)and interleukin-22(IL-22)were detected before and after treatment.To observe and analyze the changes of Th9,Th22,IL-9 and IL-22 in DILI,as well as their relationship with the de-gree and type of liver injury.Results There were significant differences in total bilirubin(TBIL),alanine aminotransferase(ALT),as-partate aminotranferase(AST)and alkaline phosphatase(ALP)before and after treatment in the mild DILI group(t were 5.777,10.347,4.225,2.948;P＜0.05),but no significant differences in international normalized ratio(INR)(t=0.210,P＞0.05).There were significant differences in TBIL,ALT,AST,ALP and INR before and after treatment in moderate liver injury group(t were 7.642,5.842,5.747,3.924,5.206;P＜0.05).There were significant differences in TBIL,ALT,AST,ALP and INR before and after treat-ment in severe liver injury group(t were 6.410,5.369,4.726,3.893,6.487;P＜0.05).There were no significant differences in TBIL,ALP and INR before and after treatment in acute liver failure group(t were 0.669,0.072,0.521;P＞0.05),while there were significant differences in ALT and AST(t were 5.466,7.184;P＜0.05).The levels of Th9 and Th22 in peripheral blood and serum IL-9 and IL-22 of related cytokines in patients with DILI were higher than those in healthy control group,and the differences between the two groups were statistically significant(t were 2.269,2.481,6.014,4.987;P＜0.05).There were statistically significant differ-ences in Th9,Th22,IL-9 and IL-22 before and after treatment in mild and moderate liver injury groups(t were 3.556,-5.906,8.258,-2.219,5.906,-8.500,7.982,-5.403;P＜0.05).There were statistically significant differences in Th9 and IL-9 be-fore and after treatment in the severe liver injury group(t were 8.411,7.250;P＜0.05),but no significant differences in Th22 and IL-22(t were-1.463,-2.038;P＞0.05).There was no significant difference in Th9 and IL-9 before and after treatment in acute liver failure group(t were 1.614,0.504;P＞0.05),but there was significant difference in Th22 and IL-22 before and after treatment(t were-3.825,-2.482;P＜0.05).There were no significant differences in Th9,Th22,IL-9 and IL-22 among different types of liver injury(F were 0.636,0.330,0.051,0.376;P＞0.05).Th9 was positively correlated with ALT(r=0.547,P＜0.001).Th22 was negatively correlated with TBIL(r=-0.657,P＜0.001)and ALT(r=-0.301,P=0.024).Conclusion Peripheral blood Th9,Th22 and related cytokines IL-9 and IL-22 are involved in the pathogenesis of DILI.Th9may play a pro-inflammatory role,while Th22may play an anti-inflammatory role,which may have nothing to do with the type of liver injury.
