Brief Psychotic Episodes and Depressed Mood in a Patient With Borderline Personality Disorder and Antiphospholipid Syndrome.

Psychiatric disorders are reported to be associated with systemic inflammatory conditions and autoimmune diseases. Antiphospholipid syndrome (APS) is a rare condition with poorly understood prevalence and incidence in the general population. Case reports have described co-occurrences of psychiatric conditions and APS. Previous case reports have indicated that patients with APS can have comorbid psychosis, anxiety, depression, and other psychiatric conditions. The association between APS and psychiatric illness, however, remains under-investigated in longitudinal studies. In this report, we present the case of a woman in her 40s who was voluntarily admitted to the psychiatric inpatient unit for treatment of auditory hallucinations within the context of borderline personality disorder. She reported a rather extensive medical and psychiatric history of several previous illnesses, musculoskeletal injuries, and hospitalizations. Due to the significant social stress and multiple comorbidities, she may be at increased vulnerability to acute exacerbations of both APS and brief psychotic episodes. In this case report, the patient had a history of three hypercoagulability incidents that were shortly followed by psychiatric admissions. This report highlights the importance of considering systemic conditions such as APS in patients presenting with psychiatric illness. Patients with APS and concomitant psychosis may benefit from screening for APS flares in the case of a psychotic break.
