Although the introduction of highly active antiretroviral therapy (HAART) has improved the survival of people living with HIV in Western countries, neurological disorders remain a significant burden for HIV-positive people. The study aims to determine the incidence and factors associated with neurological disorders in a large Taiwanese cohort of HIV-infected persons with free access to HAART.
Methods: We conducted a population-based cohort study using the Taiwan National Health Insurance Research Database and identified 13,316 HIV-positive persons from 2000 through 2010. We used direct standardization to calculate age- and sex-adjusted incidence rates based on the 2000 World Health Organization world standard population. Factors associated with neurological disorders were analyzed using a Cox proportional hazards model.
Results: The standardized incidence of neurological disorders among HIV-infected persons increased from 22.16 per 1,000 person-years in 2000 to 25.23 per 1,000 person-years in 2010.
Cognitive disorders increased significantly from 0.36 per 1,000 person-years in 2001 to 7.44 per 1,000 person-years in 2010 (trend test P < .001).
The rate of neurological disorders increased with age (adjusted hazard ratios [AHR] for age 35-44 years: 1.31, 95% CI 1.08- 1.59, 45-54 years: 1.34, 95% CI 1.04- 1.74, 55-64 years: 2.36, 95% CI 1.67- 3.33, ≥ 65 years: 2.68, 95% CI: 1.75-4.12, compared with age ≤ 24 years), hypertension (AHR 1.60, 95% CI 1.27- 2.00), substance abuse (AHR 1.72, 95% CI: 1.41- 2.10), opportunistic infection (AHR 1.99, 95% CI: 1.66- 2.39), and syphilis (AHR 1.53, 95% CI: 1.32- 1.77). The incidence of neurological disorders was negatively associated with adherence to HAART (adherence ≥ 90%: AHR 0.19, 95% CI: 0.15- 0.23).
Conclusions: The rising incidence of cognitive disorders among HIV-positive persons highlights the need to identify the causal factors of these co-infections. Receiving HAART with adherence ≥ 90% contributes to a reduced risk of neurological disorders.
