Serum cholesterol concentration and structured individual psychoanalytic psychotherapy in suicidal and non-suicidal male patients suffering from borderline personality disorder.

Findings from numerous studies suggest an association between low cholesterol levels and suicidal behavior in patients with different psychiatric diagnoses. The aims of this case-control study were to test whether cholesterol levels in male suicidal patients (N=20) with borderline personality disorder (BPD) are lower than in male non-suicidal patients (N=20) with BPD and male healthy control group (N=20), and to evaluate the influence of structured individual psychoanalytic psychotherapy on suicidal behavior. The groups were matched for age and body mass index (BMI). Results showed that serum cholesterol levels did not differ significantly between suicidal and non-suicidal BPD patients and healthy controls. The level of psychopathology (measured by Brief Psychiatric Rating Scale and Hamilton Depression Rating Scale) was significantly higher in the group of suicidal patients, which indicates the importance of evaluating particular clinical symptoms in BPD, in order to prevent suicidal behavior. Non-suicidal male patients suffering from BPD received more frequently structured individual psychoanalytic psychotherapy prior to the hospitalization than suicidal group. These results emphasized the role of this type of psychotherapy in preventing suicidal behavior in BPD patients.
