Among infections associated with HIV, tuberculosis (TB) is unique in that i
t may be transmitted to immunocompetent persons via the respiratory route,
is easily treatable once identified, may occur in early-stage HIV disease,
and is preventable with drug therapy. However, multidrug resistance is a po
tentially serious problem, even though its incidence has declined because o
f the use of directly observed therapy and other improved practices. In thi
s article, the authors describe special considerations in diagnosis and tre
atment of TB in these immunocompromised patients, including approaches reco
mmended by the US Centers for Disease Control and Prevention.
