Abstract:
Objective To study the drug resistance situation of Mycobacterium tuberculosis strains isolated from the patients with HIV/AIDS complicating tuberculosis (TB).Methods One hundred and ninety-six inpatients with AIDS complicating TB in our hospital from January 2012 to December 2015 were collected.The drug resistance situation of Mycobacterium tuberculosis strains cultured from sputum/tissue fluid/fiber liquid and pathological tissue submitted samples in the patients with AIDS complicating active TB was analyzed.The BACTEC MGIT960 systems was adopted to perform the bacterial identification.The drug sensitivity test was conducted by using 960 culture testing system.Results One hundred and ninety-six strains of Mycobacterium tuberculosis were cultured,the total drug resistance rate of Mycobacterium tuberculosis was 26.02％.These cases were divided into the ＞100/μL and ≤100/μL groups according to different CD4+ T cells count.The drug resistance situation of Mycobacterium tuberculosis to 4 kinds of first line anti-TB drugs were compared between these two groups.The comparison results found that the resistance rate of Mycobacterium tuberculosis strains to the first line anti-TB drugs had no statistical difference between the two groups (P＞0.05).The resistance rates of first line anti-TB drugs from high to low were isoniazid,rifampicin,streptomycin and ethambutol.The drug resistance rate of Mycobacterium tuberculosis strains to 5 types of drug resistant TB had no statistical difference(P＞0.05).Conclusion The drug resistance rate in the initial patients with HIV complicating TB is consistent with the average initial drugresistance level of TB patients in our country.The TB drug resistance rate in the patients with HIV complicating TB has no correlation with CD4+ T cells count.
