[Ocular manifestations in patients with human immunodeficiency virus infection before and after the introduction of highly active antiretroviral therapy].
The aim of this study was to determine and compare the incidence of various ophthalmlogic changes before anfd after the initiation of highly active antiretroviral therapy (HAART) in HIV-infected patients treated at the University Hospital for Infectious Diseases "Dr. Fran Mihaljević" in Zagreb. This retrospective longitudinal analysis included all adult patients with confirmed HIV-1 infection divided into two groups: period before HAART (1995-1997) and period after HAART (1998-2000). Only those patients who underwent at least two ophthalmologic examinations in any of the two or in both periods were considered eligible. In total, 85 patients were enrolled in the study, 50 during the 1995-1997 period and 47 in the period 1998-2000 (12 patients were monitored in both periods). The mortality rate was significantly lower in patients treated during the HAART era, with an average decrease in mortality rates of 59.3%. During the period of ophthalmologic monitoing from 1995 to 1997, only 9 (18%) patients received HAART, and 33 (70.2%) in the period 1998-2000. In total, 208 ophthalmic abnormalities were recorded, 132 (63.5%) in the first and 76 (36.5%) in the second period. Vascular changes were most frequently diagnosed (113/208 or 54.3% cases) of which cotton-wool exudates in 55 and microaneurysms in 54 cases. Cytomegalovirus (CMV) retinitis was most commonly diagnosed among infectious ocular complications (altogether 39 episodes). Changes in the anterior segment were observed in only 11/208 (5.3%) cases, while neuro-ophthalmic manifestations were sees in 39/208 patients (18.7%). The incidence of CMV-retinitis episodes in the first monitored period was 57.2 (95% CI, 38.5-86.6) per 100 years of follow-up and in the HAART era 7.6 (95% CI, 1.6-22.4; p<0.0001) per 100 years of follow-up. The visual acuity in patients from the HAART era was significantly more frequently preserved than in patients from the pre HAART era on follow-up examinations (p<0.001). Our study showed that the incidence of CMV-retinitis declined significantly in the period 1998-2000, while the decrease in the incidence rates of other ocular manifestations was less profound. In contrast to the pre HAART era, there was no worsening of visual acuity in the HAART era.
