Excerpt
At the time that the THELEP programme began, the two major concerns of the scientists working in the area of chemotherapy were the phenomena of microbial persistence and drug-resistance. It appeared certain that relapse caused by the emergence of drug-resistant Mycobacterium leprae could be prevented by employing combined (multidrug) therapy, particularly combinations including rifampicin, which was known to exert a powerfully bactericidal action against the organism. It was also clear that control of leprosy by chemotherapy would be possible only if chemotherapy of finite duration were curative; long experience with dapsone as monotherapy had demonstrated that neither patients nor the treatment services could be expected to comply with treatment of indefinitely long duration. However, rifampicin as monotherapy had recently been shown to be incapable of eradicating M leprae. And it was feared that persistence of viable organisms in the lepromatous patient, whose immune response to the organism was known to be deficient, would lead inevitably to relapse after cessation of the chemotherapy. Workers hoped that a multidrug regimen could be discovered that was curative -- i.e., capable of eradicating persisting A4 Eeprae, thereby preventing relapse.
