The association between anti-inflammatory effects of long-term lithium treatment and illness course in Bipolar Disorder.
Journal of Affective Disorders(2021)
摘要
Introduction: : Altered levels of acute-phase proteins are often described in different conditions in BD. Nevertheless, data on the association between lithium treatment and inflammatory markers in the long-term course of BD are still missing. The aim of the study was to examine the long-term course of BD concerning long-term lithium treatment, chronic inflammatory processes and symptom progression. Furthermore, the association between duration of lithium treatment and levels of hsCRP was explored. Methods: : 267 individuals (males= 139, females= 128) with BD were included. Duration of lithium treatment as well as symptom progression, defined as the increase in severity of symptoms, number of episodes a year and duration of episodes within a period of 1.5 years in the past and hsCRP were evaluated. Results: : Male individuals with symptom progression over time had significantly lower duration of lithium treatment compared to individuals without symptoms progression (U= 47.4, p=.037). There were significantly higher levels of hsCRP in male individuals with symptom progression compared to males without symptom progression (U= 47.5, p=.027). Further, there was a significant negative correlation between the duration of lithium treatment and hsCRP levels in the whole sample (r=-.276, p<.05). Conclusion: : Our results show that an altered inflammatory state may be associated with a more severe illness course in BD. Further, a longer duration of lithium treatment may be associated with lower symptom progression. The shown association between hsCRP-levels and lithium treatment duration suggests a potential antiinflammatory effect of lithium as a mediator of its significant positive outcome effect in BD.
