Bright dawn simulation compared with bright morning light in the treatment of winter depression.

In a randomized cross-over design, 7 patients with winter depression were treated with a week of a bright (1700 lx) dawn simulation (0400 to 0600) and a week of standard bright (1700 lx) morning (0600 to 0800) light therapy. The Hamilton Rating Scale for Depression scores decreased significantly for the standard light therapy (18.9 to 6.6) but not for the bright dawn therapy (18.0 to 11.3). Early morning awakening was a frequent side effect with the bright dawn simulation. Although dawn simulation at a lower illuminance may be an effective treatment, the bright dawn used in this study showed only a nonsignificant trend to lower depression ratings. The illuminance of dawn simulation should be adjusted to minimize side effects.

Adinazolam--a new antidepressant: findings of a placebo-controlled, double-blind study in outpatients with major depression.

Adinazolam mesylate, a new triazolobenzodiazepine with antidepressant properties, was significantly superior to placebo based on the following efficacy measures: number of subjects who completed the study; number of subjects whose total score on the 21-item Hamilton Rating Scale for Depression (HAM-D) decreased by 50% or more; and number of subjects who reported that the drug helped them. Mean scores on three HAM-D clusters (anxiety/somatization, sleep disturbance, and an endogenomorphic cluster) also showed significant differences in favor of adinazolam. Side effects were generally mild and transient; however, a seizure of moderate intensity occurred during rapid tapering of adinazolam from 90 to 40 mg/day. There were no significant anticholinergic effects, and no mania or hypomania was reported in any subject. No consistently significant differences were observed between subjects whose primary diagnosis was major depression and those with a diagnosis of bipolar II depression.

Induction of immunotoxicity in mice by polyhalogenated biphenyls.

Acute administration of Aroclor-1254 (500 mg/kg) or 3,4,5,3',4',5'-hexabromobiphenyl (HBB) (2-6 mg/kg) IP, profoundly inhibited the plaque forming response to subsequent challenge with sheep erythrocytes in Ah locus positive (C57Bl/6N or B6C3F1N) mice. These studies showed: the immunotoxicity results paralleled enzyme induction results insofar as HBB was approximately 100 times more potent than Aroclor 1254; neither Aroclor nor HBB treatment caused significant induction in the Ah locus negative DBA/2N mice; when B6C3F1 mice were challenged with sheep red blood cells (SRBC) 6 or 16 weeks post Aroclor 1254 treatment, substantial recovery of a PFC response was observed; when these compounds were administered to older (76-week-old) (B6C3F1 mice, severe depression of a PFC response was observed. In contrast to its profound depression of a PFC response, Aroclor-1254 (up to 1250 mg/kg) caused slight increases in lymphocyte proliferation induced by either T or B cell mitogens. A single 500 mg/kg dose of Aroclor-1254 also suppressed the ability of recipient B6C3F1 animals to reject a challenge with either the syngenic fibrosarcoma (PYB6) or the gram negative pathogen (Listeria monocytogenes).

Psychomotor retardation and agitation in depression. Relationship to age, sex, and response to treatment.

Patients with primary affective disorder who had either psychomotor agitation alone or psychomotor retardation alone were studied. Compared to psychomotor retardation, psychomotor agitation appears to be seen more frequently in women, older patients, and individuals who have a late onset to their illness. In addition, those with agitation alone appeared to have a better and faster response to electroconvulsive therapy.

Depression treated with imipramine and ECT: the DeCarolis study reconsidered.

The authors reevaluate a large prospective Italian study (437 patients) that compared high-dose imipramine with ECT treatment in the treatment of depression. The superiority of ECT was evident among patients with endogenous depression, and especially evident among those with delusional depression (83% improved with ECT versus 40% with imipramine) and depressions defined as severe (83% versus 35%).

Suicide, attempted suicide, and relapse rates in depression.

Suicide, attempted suicide, and relapse rates in 519 depressives were examined, comparing the effects of different treatments. After six months, suicide attempts were seen significantly less frequently in the ECT groups (0.8%) than in the antidepressant group (4.2%) or the "adequate" antidepressant subgroup (7.0%) Fewer suicide attempts occurred in the ECT group compared to the antidepressant group among both in those who had attempted suicide prior to admission (0% vs 10%) and in those who had not (1.1% vs 3.6%). A history of attempted suicide showed a greater risk of both suicide (2.9%) in the following year and subsequent suicide attempt (5.9%). A depressive diagnosis may be as good a predictor of suicidal behavior as a history of attempted suicide. Relapse rates did not differ between treatment groups.

The efficacy of electroconvulsive therapy and antidepressants in depression.

Electroconvulsive therapy (ECT), antidepressants, and neither treatment were compared by reviewing 609 hospitalizations for depression from 1959 to 1969. The groups receiving ECT had a significantly (p less than 0.001) greater percentage of patient who had marked improvement or a complete response (49%) than either adequate or inadequate antidepressant therapy groups (27%) or the group which received neither ECT nor antidepressants (25%). If antidepressant failures who require ECT are included in the evaluation, the percentage total improvement with ECT (90%) is significantly (p less than 0.001) greater than the adequate (74%) or inadequate (60%) antidepressant groups, or neither treatment (60%). At the end of 7 weeks of hospitalization, 74% of the ECT group had been discharged, significantly more (p less than 0.001) than the adequate antidepressant group, 54%. Delusional depressed patients responded much mor frequently to ECT.

Mortality in depressed patients treated with electroconvulsive therapy and antidepressants.

The treatments of 519 depressed patients hospitalized from 1959 to 1969 were compared in a three-year follow-up study with particular reference to mortality. The electroconvulsive therapy (ECT) group had a significantly lower mortality than the inadequate antidepressant treatment group (P less than .05) and the group that received neither ECT nor antidepressants (P less than .025). Although the adequate antidepressant treatment group had a low mortality, statistically significant differences between this and other treatment groups could not be documented. Nonsuicidal deaths (P less than .005), and particularly myocardial infarctions (P less than .01), were significantly more frequent in the inadequately treated group compared to the adequately treated group. The superiority of adequate treatment is especially striking among men and among the older age groups. The results underscore the importance of adequate treatment of depression, especially in the older man.
