Risk of depression, suicide and psychosis with hydroxychloroquine treatment for rheumatoid arthritis: a multinational network cohort study

Abstract: Objectives Concern has been raised in the rheumatology community regarding recent regulatory warnings that HCQ used in the coronavirus disease 2019 pandemic could cause acute psychiatric events. We aimed to study whether there is risk of incident depression, suicidal ideation or psychosis associated with HCQ as used for RA. Methods We performed a new-user cohort study using claims and electronic medical records from 10 sources and 3 countries (Germany, UK and USA). RA p… Show more

“…This risk was particularly signalized among patients in co-treatment with metformin or elderly (possibly due to diminished neuronal reserve and presence of mixed neurodegenerative and vascular brain injuries) [ 23 , 26 , 30 ]. However, these findings have not been corroborated in other studies [ 24 , 25 , 28 ]. Of interest to its neuropsychiatric AEs, CQ/HCQ exhibits neurotropism as CQ level in the CNS was shown to be 10–30 times higher than its serum concentration after dosing [ 31 ].…”

“…CQ/HCQ have been associated with several neuropsychiatric AEs in rheumatic diseases, infectious diseases, and COVID-19 [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. These AEs can range from relatively mild psychiatric symptoms, such as irritability, nervousness, and insomnia, to intermediate and severe clinical conditions including adjustment disorder, anxiety also with pervasive features, “personality change”, major depression, psychosis, confusion, psycho-motor agitation, delirium, and neurocognitive disorders [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ] ( Table 1 ). Notably, some evidence of increased risk of SI/SB has been described [ 21 , 22 , 27 , 28 ].…”

“…One example is the association of hydroxychloroquine with psychiatric conditions such as suicidal and self-injurious behaviors and hallucinations with hydroxychloroquine. This association has indeed been detected, in COVID-19 patients in the WHO spontaneous reporting system ( Garcia et al, 2020 ), although there is also contrary evidence pointing to the psychiatric safety of hydroxychloroquine in rheumatoid arthritis ( Lane et al, 2020 ).…”

“…In China, the Delta variant accounts for most of the new cases since the year of 2021. Previous research has implicated that the COVID-19 pandemic is likely to cause abnormality of emotion, cognition, behavior and quality of life, especially in population with chronic diseases such as systemic lupus erythematosus, rheumatoid arthritis and inflammatory bowel disease (IBD), in whom psychological distress and somatic diseases could influence mutually ( 14 16 ).…”
