Characteristics of adverse event reports among people living with human immunodeficiency virus (HIV) in Japan: Data mining of the Japanese Adverse Drug Event Report database

The development of new anti-HIV drugs and advances in antiretroviral therapy (ART) regimens have enabled longer and more effective treatments in people living with HIV (PLWH). However, the aging of PLWHs is another issue that needs to be addressed. In addition to ART, many PLWHs frequently receive medications for various comorbidities. However, real-world data on the occurrence of adverse events in PLWHs and their causative drugs are rare. Therefore, this study aimed to clarify the characteristics of adverse event reports among PLWHs in Japan. PLWH cases with adverse events were comprehensively searched and analyzed using the Japanese Adverse Drug Event Report database (JADER). Despite changes in guideline-recommended ART regimens, anti- HIV drugs were the main cause of adverse events in PLWHs throughout the study period. However, considerable variations have been observed in the reporting rate of anti-HIV drug classes registered as causative drugs in JADER, especially for anchor drugs. In other words, the reporting rate of integrase strand transfer inhibitors has increased in recent years, while that of protease inhibitors and non-nucleoside reverse transcriptase inhibitors has decreased. Immune reconstitution inflammatory syndrome was the most reported adverse event and was frequently noticed by healthcare providers managing patients with HIV infections. The trends in adverse event reports for female and older patients differed from those for the overall population. This study may provide insights that can help in the establishment of optimal management strategies for PLWHs.
