AIDS: The Centers for Disease Control and Prevention issued new guidelines for preventing and treating tuberculosis (TB) in persons with HIV. The guidelines recommend that all people with HIV be tested for TB and be treated if necessary. Also, the drug Rifampin, which can be used to treat TB, should not be used with protease inhibitors or with non-nucleoside reverse transcriptase inhibitors, as it impairs the effectiveness of those drugs. However, Rifabutin can be used with antiretroviral treatments. The guidelines also mention that there is a 2-month preventive treatment, which may be an alternative to the traditional 1-year Isoniazid treatment regimen.
