WOLFF R, Marcelo et al. Evolution of mortality and current status of an HIV-infected population cared for at a comprehensive HIV/AIDS center in Chile. Rev. méd. Chile [online]. 2006, vol.134, n.5, pp.581-588. ISSN 0034-9887.

Background: Chile, a middle-income country with an HIV epidemic of moderate proportions (global infection rate 0.2%) began a government sponsored, free, highly active antiretroviral therapy (HAART) for patients from the public health system in 2001 reaching in 2004 a 100% coverage. Arriaran Foundation (AF) is the largest public AIDS care center for adults in the country. Aim: To show the present status of the AF population and the evolution of mortality. Material and Methods: Review of AF database from 1991-2004 that at 12/31/2004 had a total cumulative population of 2,259 adult patients; an active census of 1,065 patients and admitting rate 160-190 patients per years. Results: The global mortality registered was 33.4%, with decreasing annual mortality from 15.7% of its active population in 1995 to 1.9% in 2004. As of 12/31/2004, 817 patients (76.7%) were receiving antiretroviral therapy (ART); and 19.3% either did not require nor accept it. Thirty one percent received Combivir® and nevirapine, with undetectable viral load (<400 copies per ml) in 78%. Thirty percent received Combivir® and efavirenz with undetectable viral load in 80% at last count. Both regimens were used mainly as first therapy. Lopinavir/ritonavir was received by 6.3% of patients, mainly for post failure therapy and 58% had undetectable viral load. A baseline CD4 count <200 x mm3 was present in 70% of patients, 45.3% had a count below 100 and 47.8% had clinical AIDS. At the last follow up assessment, CD4 count was <200 in 36.8%, <100 in 10.6% and 200-350 in 44.9%. Conclusion: The expanded access program to ART in a public, comprehensive AIDS care center in Chile has been highly successful in reaching high undetectability (75%), reducing mortality and improving immune status despite very advanced baseline disease
