Psychotic symptoms in patients with borderline personality disorder and concurrent axis I disorder.

OBJECTIVE: Whether psychotic symptoms are part of the fundamental psychopathology of borderline personality disorder remains in dispute. The goal of the study was to examine the incidence and nature of psychotic symptoms in a sample of patients with the disorder. METHODS: The inpatient psychiatric records of 92 patients with a discharge diagnosis of borderline personality disorder, some of whom had comorbid affective disorder or substance abuse disorder, were examined to obtain data on the presence of psychotic symptoms (narrowly defined as delusions and auditory and visual hallucinations), the duration of psychotic episodes, and the clinical characteristics of the patients. RESULTS: Twenty-seven percent of the patients had psychotic episodes, typically lasting many weeks. Comorbid affective or substance abuse disorders did not predict psychotic symptoms. CONCLUSIONS: Psychotic episodes are common but not universal among patients with borderline personality disorder, regardless of whether a concurrent axis I disorder is present. Those episodes are not necessarily brief or transient, and borderline patients who experience psychotic episodes are likely to have repeated hospitalizations.

Substance abuse in borderline personality disorder.

The impact of substance abuse on patients with borderline personality disorder was investigated. Substance abuse was common. Female patients preferred alcohol and sedatives. Male patients preferred stimulants. Substance abuse was associated with poor school performance, unemployment, and promiscuity. Depersonalization-derealization was common in nonsubstance using and alcohol-sedative using patients, but was rarely found in stimulant users. Substance abuse appears to be a devastating complication in the patient with borderline personality disorder.

Provocation of panic with carbon dioxide inhalation in patients with premenstrual dysphoria.

The effects of double breath inhalation of a 35% CO2 mixture in oxygen and placebo air inhalation were compared in 14 women seeking treatment for marked premenstrual dysphoric changes who did not have panic disorder and 12 control women. The first exposure to CO2 inhalation induced a panic attack reaction (severe subjective anxiety with autonomic symptoms) in 9 of 14 women with premenstrual dysphoria but none of the controls. Neither patients nor controls panicked in response to the air inhalation. Control subjects experienced mild anxiety and/or somatic symptoms after CO2 inhalation, but these did not resemble panic attacks and were clearly different from the response of the patient group.

Effects of clonidine on alprazolam discontinuation in panic patients: a pilot study.

Effects of adjunctive clonidine (0.15 to 0.7 mg/day) on symptoms experienced during and for 4 weeks after gradual alprazolam discontinuation were observed in panic disorder patients after 6 weeks of successful treatment. Twelve of 14 entered patients were considered to have had a sufficient period of discontinuation (2 weeks) and clonidine administration (1 week) for effects to be assessed adequately. Nine of these 12 patients reached zero dose of alprazolam in 3 to 4 weeks. However, 10 of 12 patients experienced new withdrawal symptoms and 11 of 12 experienced recurrent panic attacks during tapering. Although a greater proportion of patients were successfully discontinued in a shorter time than in a previous nonclonidine trial, clonidine did not appear to have a specific effect on relapse or withdrawal. A placebo-controlled trial is needed to discriminate between possible contributions of clonidine and other factors (e.g., physician attitude, placebo effect of pill taking) to this improved outcome.

The mitral valve prolapse--panic disorder connection.

Whether mitral valve prolapse (MVP) is more common in patients with panic disorder (PD) and agoraphobia with panic attacks (AgP) than in the normal population is controversial. A related issue is whether the presence of MVP in such patients has any clinical or biological significance. Echocardiograms were performed on 36 patients with PD/AgP and 22 normal controls. MVP was found to be more common in PD/AgP patients than in normal controls. However, MVP in the patients was mild and not associated with thickened mitral leaflets or small left ventricular size. Moderate or severe prolapse was uncommon in both groups. Patients with MVP had trends to higher heart rate and prolonged QTc interval on EKG, and reported more respiratory difficulty during panic attacks compared to patients without MVP. Lactate infusion did not affect patients with MVP differently than patients without MVP. The authors conclude that MVP is more common in patients with PD or AgP than in normal controls, but is of doubtful clinical significance.
