There is accumulating evidence from clinical trials and cohort studies that
highly active antiretroviral combination therapy is effective at halting i
mmunologic and clinical progression of human immunodeficiency virus (HIV).
Its impact at a population level is less well known because the regimes may
be difficult to tolerate and compliance poorer. The authors make use of po
pulation data for almost all of the HIV-infected people in Scotland in 1997
who were under clinical care and monitor their response to therapy during
the first year when these effective treatments became widely available. Mor
e than two thirds of the HIV-positive patients were on same form of antiret
roviral therapy during the year. The authors show that all treated groups,
even those who were on changing regimes, showed net improvement in immunolo
gic status during the year. For the group of patients on triple or quadrupl
e therapy, there was an average increase of more than 100 CD4 cells/mm(3) o
ver the year, with other treatment groups showing more modest, but signific
ant, increases.
