Marked improvement in survival among adult Croatian AIDS patients after the introduction of highly active antiretroviral treatment.
We compared the survival of patients following the first AIDS event in Croatia from the period 1986-1996 to the period 1997-2000. A total of 72 (81.8%) out of 88 patients from 1986-1996 and 18 (32.1%) out of 56 from 1997-2000 died. Survival following the first AIDS-defining illness markedly improved in the period 1997-2000 compared to the period 1986-1996 (adjusted Hazard Ratio (HR) for patients surviving more than 6 months: 0.11, 95% confidence interval (95% CI) = 0.04-0.29). A CD4+ cell count of < 100 x 10(6)/L was an independent risk factor for patients surviving up to 2 years (adjusted HR = 1.96, 95% CI = 1.1-3.43, p = 0.02). Patients with tuberculosis or fungal infections had a longer survival when compared to other diagnosis (adjusted HR = 0.53, 95% CI = 0.32-0.90, p = 0.01). However, despite dramatic survival benefit of combination antiretroviral therapy, mortality at six months following the first AIDS event was similar in the two study periods and the one-year probability of death was still substantial (27.2%) in the period 1997-2000.
