Suicide Attempts in Patients With Systemic Lupus Erythematosus: A Single-Center Experience and Literature Review

BackgroundSuicide is a global health issue, and an increase in suicide risk has been found in patients with systemic lupus erythematosus (SLE) when compared with the general population. However, only a few studies have described suicide attempts in patients with SLE in detail.ObjectiveThe aim of this study is to describe the suicide attempts in patients with SLE in a tertiary hospital in Taiwan.MethodsA total of 8 patients with SLE, 7 women and 1 man, with 12 suicide attempts among them were identified among 2469 patients visiting a tertiary medical center in Taiwan, from March 1, 2003 to November 30, 2013. Their demographic data, lupus manifestations throughout their disease course, laboratory data, and details of their suicide attempts were retrospectively documented. We also searched the MEDLINE database and found 4 articles in English describing suicide attempts in 14 patients with SLE.ResultsThe median age of the 8 patients with SLE in our hospital who attempted suicide was 33 years (range: 19–77 years). Neuropsychiatric SLE developed in 5 (63%) of these patients before the attempts, and psychiatric disorders were diagnosed in 5 (63%) of them. We also observed a high prevalence of neuropsychiatric SLE (71%) and psychiatric disorders (86%) in patients with SLE in the literature who had attempted suicide.ConclusionWe demonstrated that previous neuropsychiatric SLE and comorbid psychiatric disorders are prevalent in patients with SLE who attempt suicide. If a rheumatologist suspects that a patient with SLE has a psychiatric disorder, he or she should refer the patient to a psychiatrist.
