Abstract
- Background
Domestic data on antiretroviral drug (ARV) resistance are limited, while alterations in ARV resistance are expected as the incidence of human immunodeficiency virus (HIV) infection increases. We evaluated the ten-year change in ARV resistance in people with HIV (PWH) in Korea.
Materials and Methods
Adults aged ≥19 years and diagnosed with HIV infection between January 2010 and December 2020 at a 750-bed municipal hospital were retrospectively reviewed. Data on clinical characteristics and resistance mutation test results were collected. The study population was divided into three-year intervals according to diagnosed year and their clinical characteristics were compared.
Results
A total of 248 PWH were analyzed, and ARV resistance was detected in 30 of them (12.1%). Resistance was detected most frequently in PWH aged ≤29 years (16, 6.5%), and the median percentage of resistance detection per year was 14.3% (interquartile range, 12.7 - 16.1). The trend of the overall prevalence of ARV resistance mutations slightly decreased and then increased over time (15.3% in 2012 - 2014, 9.6% in 2015 - 2017, and 12.9% in 2018 -2020). The prevalence of the non-nucleoside reverse transcriptase inhibitor (NNRTI) resistance markedly decreased over time (15.3% in 2012 - 2014, 8.7% in 2015 - 2017, and 2.4% in 2018-2020), while that of protease inhibitor (PI) and integrase strand transfer inhibitor (INSTI) increased from 0 until 2018 to 3.5% and 8.2% in 2018 - 2020, respectively.
Conclusion
The trend of NNRTI resistance has decreased over time, and resistance to PIs and INSTIs increased from 2018. Therefore, continuous monitoring of ARV resistance pattern is necessary.
