Abstract:
Objective To investigate the risk factors of hypersensitivity induced by compound sulfamethoxazole (Co-SMZ)in patients with human immunodeficiency virus (HIV)infection.Methods A retrospective study was performed in 111 patients with HIV infection receiving prophylactic Co-SMZ at the Department of Infectious Diseases,the Third People′s Hospital of Nantong City,Jiangsu Province from January 2014 to December 2014.Data including age,gender,interval time from diagnosis of HIV infection to hospitalization,history of drug allergy,and the counts of CD3 + T cell,CD4 + T cell,CD8 + T cell and natural killer (NK)cell on the day when the medicine was administrated for the first time were recorded. All the patients were followed up for two months.Student t test was used in data with normal distribution or approximate normal distribution.Rank sum test was used in data with skew distribution.The count materials were examined byχ2 test.Results Among the 111 patients with HIV infection,there were 107 males and 4 females with average age of (45 .7±11 .1)years old.The interval time from taking Co-SMZ to hypersensitivity was (14.0±7.6)d.There were differences in the counts of CD4 + T cell and NK cell between patients with hypersensitivity and without hypersensitivity (both P <0.05).Multivariate analysis showed that NK cell was a risk factor for inducing hypersensitivity (OR=1 .010,95 %CI :1 .005 -1 .017, P =0.001).The area under of receiver operating characteristic curve predicting hypersensitivity induced by Co-SMZ was 0.748 (95 %CI :0.647-0.850,Z =4.701 ,P =0.001).The best predictor was 109.80/μL with sensitivity of 63.2% and specificity of 84.7%.Conclusion In patients with HIV infection,NK cell might be associated with hypersensitivity induced by Co-SMZ.
