  ABSTRACT: Augmentation with TSH-suppressive L-thyroxine (T4) has been shown to improve the course of illness in otherwise refractory affective disorders. This collaborative study investigates whether T4 augmentation for a minimum of 12 months decreases bone mineral density (BMD) in 26 pre- and post-menopausal women with affective disorder. We measured BMD at the femoral neck, Ward's triangle, trochanter and lumbar vertebrae (L1-L4) in 13 premenopausal and 13 postmenopausal women with affective disorder using dual energy X-ray absorptiometry. BMD was expressed as g/cm(2) and as a Z-score, calculated using bone density data from the international reference population standard. The Z-scores for the pre- and post-menopausal women were within the reference range of the age and sex matched population standard. BMD for the composite group also did not differ either from the population standard. BMD in the lumbar spine and hip did not differ significantly between the pre- and post-menopausal groups. However, there were a relatively high number of postmenopausal patients with BMDs one S.D. lower than the population standard. This is a cross-sectional study with a relatively small sample size. The study demonstrates that T4 augmentation treatment does not reduce BMD to a clinically significant degree in many women with affective disorder. However, the resilience of bone structure to T4 treatment may vary with site and menopausal status. This study underscores the need for regular assessment of BMD during adjunctive thyroid treatments for affective disorder, especially in postmenopausal women.

  ABSTRACT: Recent reports of sustained hypertension in some patients receiving venlafaxine have rekindled concerns about antidepressant-induced hypertension. This study examined sitting and standing systolic and diastolic blood pressure, pulse rate, and rate of sustained hypertension in 796 depressed patients (mean +/- SD age, 40 +/- 11 years) taking fluoxetine 20 mg daily for up to 12 weeks. A modest reduction in sitting and standing systolic (p < 0.001) and diastolic (p < 0.001) blood pressure measures were observed in the entire patient sample. Patients with pretreatment diastolic blood pressure < 60 mmHg (N = 32) showed a modest increase in mean diastolic blood pressure (p < 0.001), whereas patients with pretreatment diastolic blood pressure > or = 90 mmHg and < or = 95 mmHg (N = 57) had a modest reduction in mean diastolic blood pressure (p < 0.001). Patients with preexisting, stable cardiovascular disease (including hypertension) (N = 35) showed no significant blood pressure change (p = not significant). Of the patients receiving fluoxetine, 1.7% had sustained hypertension for > or = 3 consecutive clinic visits-a rate significantly lower than that previously reported with venlafaxine (4.8%) (chi2 = 13.3, p < 0.001) and similar to that previously seen with placebo (2.1%). In conclusion, these data demonstrate a low rate of sustained hypertension (1.7%) during short-term fluoxetine treatment.

  ABSTRACT: Since recent research has suggested that the major metabolites of progesterone are barbiturate-like modulators of GABAergic function, we undertook a pilot study of the efficacy of micronized progesterone in attenuating withdrawal and facilitating discontinuation in benzodiazepine-dependent patients with a minimum of 1 year of continuous daily use. Forty-three patients taking a mean daily dose of 16.2 mg of diazepam (or its equivalent) were assigned, doubleblind, to treatment with either placebo (n = 13) or progesterone (n = 30). Progesterone was titrated to a mean daily dose of 1983 mg, and was co-administered for 3 weeks, after which the benzodiazepine was tapered by 25% per week. Progesterone (or placebo) was then continued for 4 weeks before being discontinued. There was no progesterone versus placebo difference in the severity of taper withdrawal. Withdrawal checklist change scores were 17.3 for progesterone and 16.5 for placebo (F 0.63; df 2.31; n.s.), and the Hamilton rating scale for anxiety change scores were 7.8 for progesterone and 6.3 for placebo (F 0.22; df 2.30; n.s.). There was no difference in ability to remain drug-free at 12 weeks post-taper, with 57% of progesterone-treated patients, and 58% of placebo-treated patients having a successful outcome.

  ABSTRACT: Patients with generalized anxiety disorder (N=107) who had been long-term benzodiazepine users (average duration of use=8.5 years) were enrolled in a benzodiazepine discontinuation program that assessed the effectiveness of concomitant imipramine (180 mg/day) and buspirone (38 mg/day) compared to placebo in facilitating benzodiazepine discontinuation. After a benzodiazepine stabilization period taking either diazepam, lorazepam, or alprazolam, patients were treated for 4 weeks with imipramine, buspirone, or placebo under double-blind conditions while benzodiazepine intake was kept stable (treatment phase). Patients then entered a 4-6 week benzodiazepine taper and a 5-week posttaper phase with imipramine, buspirone, and placebo treatment being continued until 3 weeks into the posttaper phase, at which time all patients were switched to placebo for 2 weeks. Benzodiazepine plasma levels were assayed weekly. Benzodiazepine-free status was assessed 3 and 12 months posttaper. Study subjects were long-term benzodiazepine users with an average of three unsuccessful prior taper attempts. The success rate of the taper in this study was significantly higher for patients who received imipramine (82.6%), and nonsignificantly higher for patients who received buspirone (67.9%), than for patients who received placebo (37.5%). The imipramine effect remained highly significant even after the analysis adjusted for three other independent predictors of taper success: benzodiazepine dose, level of anxious symptoms at baseline, and duration of benzodiazepine therapy. Management of benzodiazepine discontinuation can be facilitated significantly by co-prescribing imipramine before and during the benzodiazepine taper. Daily benzodiazepine dose, severity of baseline symptoms of anxiety and depression, and duration of benzodiazepine use were additional significant predictors of successful taper outcome.

• Article: The effect of personality on withdrawal severity and taper outcome in benzodiazepine dependent patients.

  ABSTRACT: Personality psychopathology exerts a significant and independent effect on the course of benzodiazepine (BZ) discontinuation, worsening the subjective severity of withdrawal symptoms and significantly increasing the occurrence of early taper failures. One hundred and seventy-one patients participating in a BZ discontinuation programme were administered several personality measures prior to taper. Patients were stabilized for 3 weeks at their baseline BZ dosage and then tapered off 25% per week over 4 weeks, with the option to extend up to 6 weeks if necessary. High levels of passivity and dependency as assessed by the MMPI Dependence subcluster, and at a trend level high Eysenck Neuroticism and high TPQ Harm Avoidance contributed significantly to the prediction of benzodiazepine withdrawal severity. Though there was a high correlation between personality measures, psychopathology and adjusted BZ dose, the effects of personality on withdrawal severity was significant, particularly in the initial phases of BZ taper, when taper severity was still relatively mild. These findings indicate that clinical decisions on how to manage BZ tapering should be guided by personality assessments, in addition to the usual considerations of BZ dosage, residual psychopathology, duration of treatment, etc. The potential for difficulty with discontinuation related to personality traits should be one of the factors weighted in the risk-benefit assessment made in the planning of benzodiazepine treatment for patients with anxious symptomatology.
