Study on the correlation between suicide in patients with bipolar disorder depressive episodes and IgA
Objective To analyze the association between suicidality and biological parameters in patients with bipolar depression episodes and to provide a basis for evaluation and monitoring.Methods A retrospective cross-sectional study was conducted on hospitalized patients with bipolar depression episodes at Beijing Anding Hospital,Capital Medical University,from January 2014 to December 2017.The patient data including demographic,clinical,and biological parameters were collected from the electronic medical records system and analyzed using R(version 4.2.2)statistical software.Results A total of 2 027 patients with bipolar depression episodes were included,with 417(20.6％)exhibiting suicidal ideation or behavior.Compared to the non-suicidal group,the suicidal group had a higher proportion of females and comorbid medical conditions.Additionally,serum IgA and testosterone(TES)levels were higher in the suicidal group(all P＜0.05).Multivariate Logistic regression analysis revealed significant positive associations between IgA,comorbid medical conditions,and suicidal ideation and behavior.Conclusion Elevated serum IgA levels and the presence of comorbid medical conditions are risk factors associated with suicidal ideation and behavior in patients with bipolar depression episodes.This finding contributes to more accurate risk identification and effective intervention strategies.
