ABSTRACT

Background: \r\n', u'In the antituberculosis chemotherapy, shortening treatment course, and applying new high effective methods are top prioritized. Of which,the immunotherapy with M vaccea an environmental saprophyte, combined with the antituberculosis medicines all over the world has been applied since 1985, aimed to enhance the host immune responses.\r\n', u'Objectives:\r\n', u'To evaluate the results after 6 months of shortened course anittuberculosis chemotherapy by combining the immunotherapy withM vaccae.\r\n', u'Subjects and method: \r\n', u'233 newly diagnosed pulmonary tuberculosis patients with AFB smear (+) selected from Centers for Tuberculosis Control in some districts of Ha Tay and Ha Noi.

There are 88.5% and 100% for group B, 85.6% and 98.8% for group A at the same time to achieve a negative sputum culture for M. tuberculosis. IgM responses against M. tuberculosis sonicated antigen before and after the follow-up time in Group A are not changed, whereas this level of the immunotherapy group had reduced significantly at the 6th moth (P<0.05). There is no responses in IgC to M. tuberculosis of both groups during the same follow-up period. The mean weight of patients in group B was higher than that of group A after 2 and 6 months of treatment.\r\n', u'Conclusion:\r\n', u'M. vaccae vaccine brings good benefits when be combined with the chemo-immunotherapy for newly diagnosed pulmonary tuberculosis patients with AFB smear (+). The negative sputum indicators and clinic improvements in the chemo- immunotherapy group of treatment are better than that of chemotherapy only. This study created more effective method for treating tuberculosis infection.\r\n', u'
