Insights
Highly active antiretroviral therapy (HAART) significantly reduced cytomegalovirus retinitis (CMVR) and other fundus lesions in Chinese AIDS patients. Low CD4+ cell counts and HAART-naive status remain major risk factors for these conditions.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Public Health
Background:
- Acquired immunodeficiency syndrome (AIDS) can lead to various ocular complications, including cytomegalovirus retinitis (CMVR).
- The introduction of highly active antiretroviral therapy (HAART) has transformed HIV/AIDS management globally.
- Understanding the impact of HAART on fundus lesions in Chinese populations is crucial for clinical practice.
Purpose of the Study:
- To investigate the prevalence of CMVR and other fundus lesions in Chinese patients with AIDS.
- To compare these prevalence rates before and after the widespread adoption of HAART in China.
Main Methods:
- A retrospective study was conducted at a referral center in Beijing.
- Data from 173 HAART-naive and 267 HAART-treated individuals with AIDS were analyzed.
- Ophthalmic examinations, including fundus photography and CD4+ T-cell counts, were performed.
Main Results:
- Prevalence of CMVR, microvascular retinopathy, and optic neuropathy was significantly lower in the HAART group compared to the HAART-naive group.
- Microvascular retinopathy was associated with HAART-naive status and older age.
- CMVR was strongly associated with low CD4+ cell counts (<50 cells/μL) and HAART-naive status.
Conclusions:
- HAART significantly decreases the prevalence of CMVR and microvascular retinopathy in Chinese patients with AIDS.
- Low CD4+ cell count and lack of HAART are identified as the primary risk factors for these ocular conditions.
- Findings are consistent with observations in Western countries, highlighting the global impact of HAART on AIDS-related eye diseases.
Purpose:
To determine the prevalence of cytomegalovirus retinitis (CMVR) and other fundus lesions in subjects with acquired immunodeficiency syndrome (AIDS) before and after the introduction of highly active antiretroviral therapy (HAART) in China.
Methods:
The retrospective study included subjects with AIDS who consecutively attended a third referral center in Beijing before and after HAART was introduced. Comprehensive systemic and ophthalmic examinations, including CD4+ T-cell count, ophthalmoscopy, and fundus photography, were carried out.
Results:
A total of 173 HIV-infected, HAART-naive individuals and 267 people undergoing HAART were included in the study. The HAART-naive group as compared with the HAART group was significantly older (39.5 ± 11.5 years versus 36.7 ± 11.2 years; p = 0.02) and included significantly more men (p = 0.045). Prevalence of CMVR, microvascular retinopathy, and optic neuropathy in the HAART group (9.0 ± 1.8%, 7.9 ± 1.7%, and 4.9 ± 1.3%, respectively) were significantly (all p≤0.001) lower than in the HAART-naive group (20.2 ± 3.1%, 31.2 ± 3.5%, and 13.9 ± 2.6%, respectively). Microvascular retinopathy was significantly associated with HAART-naive status (p<0.001; odds ratio [OR] 0.20; 95% confidence interval [CI] 0.12, 0.36) and higher age (p = 0.002; OR 1.04; 95% CI 1.10, 1.06). Cytomegalovirus retinitis was significantly associated with CD4+ cell count <50 cells/μL (p = 0.001; OR 5.50; 95% CI 1.95, 15.5), HAART-naive status (p = 0.02; OR 0.23; 95% CI 0.07, 0.79), and lower best-corrected visual acuity (p<0.001; OR 5.44; 95% CI 2.11, 14.0).
Conclusions:
As in Western countries, prevalence of CMVR and microvascular retinopathy in Chinese subjects with AIDS were significantly associated with a low CD4+ cell count and a HAART-naive status as the 2 major risk factors.
