[Treatment of borderline personality disorder with opioid antagonists: buprenorphine, nalmefene, naloxone and naltrexone in the treatment of dissociative symptoms, self-mutilation and suicidal behavior].

OBJECTIVE

Recent theory has proposed that a dysfunction of the opioid system modulates mood, reward and pain; seems to be unstable in people with Borderline Personality Disorder. Our purpose is to analyze the evidence on the efficacy of the use of buprenorphine, nalmefene, naloxone and naltrexone, in the treatment of dissociative symptoms, self-mutilation and suicidal behavior of these patients.

METHOD

We conducted a systematic search of MEDLINE and LILACS databases, to retrieve relevant articles. Included studies were experimental and observational designs of borderline personality samples in which dissociative symptoms, self mutilation or suicidal behavior was reported as an outcome and evaluated with some impact measures.

RESULTS

A total of eight studies were reviewed. These provided interesting expectations about posible treatment lines in Borderline Personality Disorder using opioid antagonists. The subgroup most benefited was the one who has analgesia and highest number of diagnostic criteria.

CONCLUSIONS

Studies of higher methodological quality are needed, in larger population samples and using control of confounding variables that allow us to estimate a value power calculation, and thus be able to support firm conclusions.
