RESUMO

Objective To analyze the drug resistance status of mycobacterium tuberculosis in patients with double immunization of human immunodeficiency virus (HIV) and tuberculosis (TB) by phage bioassay (PhaB),and to optimize the control strategy.Methods One hundred and twelve cases of HIV/TB infected patients.in Chongqing Ninth People's Hospital were treated with PhaB method,and the drug susceptibility testing results were compared with 208 cases of simple pulmonary tuberculosis patients.Results The anti-tuberculosis drug resistance rate of HIV/TB patients was lower than that of simple pulmonary tuberculosis patients.The resistance rates of 5 common anti-tuberculosis drugs in HIV/TB patients were 7.14% of isoniazid (INH),7.14% of pyrazinamide (PZA),5.36 % of rifampicin(RFP) streptomycin(SM),and 4.46 % of ethambutol (EMB),compared with simple pulmonary tuberculosis(resistance rates of RFP were 17.31%,IN H 13.46 %,PZA 11.54 %,EMB 10.58 %,SM 9.62 %),RFP resistance rate of HIV/TB infected patients was lower(P<0.05).There was no significant difference between two groups in the other four anti-tuberculosis drug(P>0.05).The coincidence rate with the absolute concentration method were INH 96.4%,RFP 98.2%,PZA 96.4%,EMB 93.8% and SM 96.4%,respectively.Conclusion The resistance rate of mycobacterium tuberculosis to RFP in patients with HIV/TB infection in this region is lower than that in patients with common pulmonary tuberculosis,which is related to the good medication compliance of these patients.PhaB has the characteristic of fast,simple,without special equipment,it can be used as a rapid screening of mycobacterium tuberculosis drug resistance method.

RESUMO

Objective To analyze the relationship between hepatitis B virus gene mutation at site 1896 in precore region and genotypes as well as liver function parameters. Methods The fluorescent quantitative PCR and sequencing method were applied to measuring the relevant indicators in 50 patients with chronic hepatitis B. Results There was significant difference in ALT level between hepatitis B patients with site 1896 mutation and ones with wild-type; and HBV mutation at site 1896 in precore region was unrelated to the genotypes. Conclusion HBV mutation at site 1896 in precore region may be associated with continous viral invasion invasion into hepatocytes.
