Detailed Description:

Mycobacterium tuberculosis causing tuberculosis (TB) is a major global public health problem. Because of increasing multi drug resistance and the long treatment period of at least six months, new therapeutic options are urgently needed. In countries like Ethiopia where TB is endemic, chronic worm infection is also highly prevalent. Recent data support that helminth infection might limit the host response against TB by inhibition of the TH1-response that is crucial in controlling the disease. In this study we want to test the hypothesis that Albendazole treatment of patients coinfected with helminths and TB could improve clinical outcome in addition to chemotherapy against TB. Additionally we will investigate the immunological interactions between TB and chronic helminths infection.
