TREATING SOME TB

ANCHOR LEAD: A NEW REGIMEN FOR TB WON'T HELP WITH DRUG RESISTANT STRAINS, ELIZABETH TRACEY REPORTS

For the majority of people exposed to tuberculosis, a new regimen developed by Richard Chaisson and colleagues at Johns Hopkins is good news indeed, simplifying and shortening treatment. But for those with very virulent forms of the disease, more research is needed.

CHAISSON: This new regimen is only effective for people who have drug susceptible TB. For people who have drug resistant TB, MDR TB, or XDR TB, the highly resistant strains of TB, we need to find new regimens. We've evaluated some of them but we now need to get into people. The first priority is to develop drugs to treat people who are sick with these drug resistant forms of TB, then treating the people who are exposed to these resistant strains is also a high priority. :32

Chaisson feels confident that this new regimen points the way toward drugs and strategies that will also prove effective in more resistant TB strains. At Johns Hopkins, I'm Elizabeth Tracey.
