Placebo-controlled trial of fluoxetine and phenelzine for obsessive-compulsive disorder.

OBJECTIVE: It is now well documented that fluoxetine is a viable treatment option for patients with obsessive-compulsive disorder (OCD), and there is a small body of evidence indicating that monoamine oxidase inhibitors may be effective in at least a subset of patients. The authors conducted a 10-week placebo-controlled trial of these two agents in patients who met DSM-III-R criteria for OCD. METHOD: Sixty-four subjects were randomly assigned to receive placebo, phenelzine (60 mg/day), or fluoxetine (80 mg/day). These doses were achieved by the end of week 3 of the active phase of the study. Outcomes were assessed with standardized instruments to measure OCD, mood, and anxiety. RESULTS: Fifty-four patients completed the study. There was a significant difference among the three treatments on one OCD scale, with fluoxetine-treated patients improving significantly more than those in the placebo or phenelzine group. A subgroup of OCD patients with symmetry obsessions did respond to phenelzine. CONCLUSIONS: This study provides no evidence to support the use of phenelzine in OCD except possibly for those patients with symmetry or other atypical obsessions. There was also no support for the hypothesis that patients with high levels of anxiety would respond preferentially to phenelzine.

The Massachusetts General Hospital (MGH) Hairpulling Scale: 2. reliability and validity.

Assessment of symptom severity and change in chronic hairpulling has been limited by the absence of a psychometrically validated clinical rating scale. The Massachusetts General Hospital Hairpulling Scale demonstrated test-retest reliability, convergent and divergent validity, and sensitivity to change in hairpulling symptoms.

Long-term follow-up of 85 patients with obsessive-compulsive disorder.

In this study, long-term outcome for patients with obsessive-compulsive disorder treated with serotonin reuptake inhibitor medications was examined. The records of 85 patients who had first been evaluated at least 1 year previously (the mean follow-up period was 773 days) were reviewed. Information was collected on age at onset of symptoms, time since first evaluation, and scores on several scales measuring symptom severity, including the Yale-Brown Obsessive Compulsive Scale. Comparison of these baseline data with Yale-Brown scale scores at the most recent follow-up visit showed that 74 (87%) of the patients had responded to treatment. No predictors of improvement were found.

Changes in DSM-III-R axis II diagnoses following treatment of obsessive-compulsive disorder.

Seventeen patients with obsessive-compulsive disorder and concomitant personality disorders were treated with pharmacologic and/or behavioral therapy and reassessed after 4 months. Nine of the 10 patients who responded to treatment for obsessive-compulsive disorder no longer met criteria for a personality disorder. Of the seven nonresponders, five continued to meet criteria for a personality disorder.

Dissociative symptoms in patients with obsessive-compulsive disorder.

To clarify the relationship between dissociative symptoms and obsessive-compulsive disorder (OCD), 100 patients with OCD were assessed with standardized instruments measuring symptoms of OCD, dissociation, and depression. Diagnoses of personality disorders and dissociative disorders were made using structured interviews. Compared with a previous study, OCD patients had dissociation scores slightly higher than normal controls and comparable to patients with other anxiety disorders. Patients with elevated dissociation scores had more severe OCD symptoms, were more depressed, and were more likely to have a personality disorder than patients with low dissociation scores. Although dissociative symptoms were frequently reported by OCD patients, symptoms of OCD may also mimic dissociation in some patients.

Cingulotomy for refractory obsessive-compulsive disorder. A long-term follow-up of 33 patients.

To evaluate the feasibility of cingulotomy as a treatment for patients with intractable obsessive-compulsive disorder, we evaluated the records of all 35 patients with this diagnosis who had undergone one or more such procedures at Massachusetts General Hospital, Boston, during the last 25 years. Retrospectively, all but two of these patients met DSM-III-R criteria for obsessive-compulsive disorder. Six patients were deceased; four by suicide. Questionnaires were sent to the remaining 27 patients with obsessive-compulsive disorder; 17 patients returned the questionnaire and another agreed to an interview without completing the forms. Sixteen of these 18 patients participated in a telephone interview, and patient reports were corroborated by an informant in 10 cases. Despite the presence of some side effects, such as easily controlled seizures (9%) and transient mania (6%), the results of this investigation support the use of cingulotomy as a potentially effective treatment for patients with severe and disabling obsessive-compulsive disorder. With the use of very conservative criteria, we estimated that at least 25% to 30% of the patients benefited substantially from this procedure. Similar results were found in a preliminary prospective study of four patients who recently underwent cingulotomy after state-of-the-art preoperative treatments had failed.

Standardized assessment of personality disorders in obsessive-compulsive disorder.

We assessed 96 patients with obsessive-compulsive disorder for DSM-III personality disorder diagnoses with a standardized interview instrument (Structured Interview for the DSM-III Personality Disorders). Fifty patients (52%) met criteria for at least one personality disorder, with mixed, dependent, and histrionic personality disorders most frequently diagnosed. Compulsive personality disorder was diagnosed in only 6 patients (6%), 5 of whom had had onset of obsessive-compulsive symptoms before the age of 10 years, indicating that DSM-III compulsive personality disorder is not invariably a premorbid condition for the development of obsessive-compulsive disorder. Schizotypal personality disorder, at 5%, was found to be less common than in past samples, reflecting differences in either assessment methods or sampling.

Symptomatic HIV infection of the CNS in a patient without clinical evidence of immune deficiency.

Major depression with psychotic features, dementia, and focal neurologic abnormalities appeared in a Haitian man without AIDS or other syndromes of immune compromise. Neurologic evaluation, including brain biopsy, was nondiagnostic, but CSF culture revealed human immunodeficiency virus (HIV).
