Changes in survival and causes of death among people living with HIV: Three decades of surveys from Tokyo, one of the Asian metropolitan cities

Introduction: Survival among people living with HIV (PLWH) has dramatically improved in the antire-troviral therapy (ART) era. This is the first study in Asia to describe three decades of surveys on survival and causes of death among PLWH. Methods: We included 1121 HIV-infected patients, categorized into three period groups according to date of first visit: 1986-1996 (Pre-ART); 1997-2007 (Early-ART); and 2008-2018 (Late-ART). Results: Ten-year all-cause mortality has reduced from Pre-ART (49.6/1000 person-years) to Late-ART (6.3/1000 person-years). Mortality for AIDS-defining illnesses (ADIs) has also reduced from Pre-ART (34.4/1000 person-years) to Late-ART (2.9/1000 person-years), and mortality for non-ADIs has reduced from Pre-ART (11.7/1000 person-years) to Late-ART (2.9/1000 person-years). In the ART-era, deaths from non-AIDS-defining malignancies and unnatural events including suicide represented the majority of non-ADI-related deaths and mortality rates of non-AIDS defining malignancies and unnatural cause event were not different between each group (3.4, 1.9 and 2.5/1000 person-years). Crude cumu-lative survival improved over the study period, and 10-year survival ratios of HIV-infected patients to the general Japanese population approached 1.00, from Pre-ART (0.66) to Late-ART (0.99). Even in the Late -ART period, survival remained lower in patients with a history of ADIs than in those without, but the difference in 5-year mortality between these groups has shrunk in the Late-ART compared to the Pre -ART. Conclusions: Mortality for ADIs and non-ADIs in PLWH has reduced in the Early-ART and Late-ART. To improve survival for PLWH further, early HIV detection and treatment and good management of non-AIDS-defining malignancies and mental disorders are needed. (248/250).
