The neuroendocrine response to L-5-hydroxytryptophan was compared in 37 prepubertal children who met the Research Diagnostic Criteria for major depressive disorder with that in 23 normal children with no lifetime history of any psychiatric disorder and very low rates of depression in both first- and second-degree relatives. Intravenous L-5-hydroxytryptophan (0.8 mg/kg) was given over a 1-hour interval after preloading with oral carbidopa, an inhibitor of peripheral but not central L-5-hydroxytryptophan metabolism. L-5-Hydroxytryptophan, a precursor of serotonin, increases serotonin turnover in the central nervous system when given after carbidopa. Seven (19%) of the 37 children with major depressive disorder and two (9%) of the 23 normal children had nausea or vomiting and therefore did not complete the full infusion. They were subsequently excluded from data analysis. After this stimulation, prolactin, cortisol, and growth hormone secretion were compared between diagnostic groups. The depressed children secreted significantly less cortisol (effect size, 0.70) and significantly more prolactin (effect size, 0.83). There was a sex-by-diagnosis interaction in prolactin response to L-5-hydroxytryptophan and, on examination, the prolactin hypersecretion was seen in depressed girls but not in depressed boys compared with same-sex controls. There was no significant stimulation of growth hormone in either group. These findings are consistent with dysregulation of central serotonergic systems in childhood major depression.

Considerable research shows that serotonin dysfunction is implicated in major depression. Paroxetine is an investigational antidepressant that appears to act by selectively blocking neuronal serotonin uptake. Seventy-two outpatients with moderate-to-severe major depression entered this 6-week, double-blind comparison of paroxetine and placebo. The results showed clear and significant superiority of paroxetine on all of the major outcome variables. These included physician-rated measures such as the Hamilton Rating Scale for Depression and its four factor scores, the Clinical Global Impressions scale, the Montgomery and Asberg Depression Rating Scale, and the Raskin Depression Scale. Results on these agreed well with patient-rated measures like the Hopkins Symptom Checklist and Patient Global Evaluation Scale. Paroxetine was also very well tolerated. Nausea and constipation occurred significantly more often with paroxetine, but only 9% of paroxetine patients dropped out of the study due either in whole or in part to an adverse effect. This compares to 8% of the placebo patients who were discontinued for the same reason. This study suggests that paroxetine is a safe and effective medication for the treatment of major depression.

Depressive illness among the elderly is an important public health concern. However, treatment of the elderly may be complicated by age-related changes in physiology, general medical status, and susceptibility to side effects. There is therefore a need for improved treatment modalities for depressed elderly patients. Paroxetine is an antidepressant that acts through selective inhibition of serotonin reuptake. It lacks the anticholinergic and cardiovascular side effects of most first- and second-generation antidepressants. The authors present the combined data from two similarly designed comparisons of paroxetine and doxepin in outpatients over 60 years of age with major depression. The results show that paroxetine was an effective as doxepin in alleviating depression as measured on the Hamilton Rating Scale for Depression (HAM-D) total score, the Montgomery and Asberg Depression Rating Scale (MADRS), and the Hopkins Symptom Checklist (SCL) depression factor score. Paroxetine was significantly superior to doxepin on the Clinical Global Impressions (CGI) scale for severity of illness, the HAM-D retardation factor, and the HAM-D depressed mood item. Doxepin produced significantly more anticholinergic effects, sedation, and confusion. Paroxetine was associated with more reports of nausea and headache. These results suggest that paroxetine may be a valuable tool for the treatment of major depression in the elderly.

In a six-week double-blind randomized trial, preceded by a one-week period of single-blind placebo treatment, the efficacy and the side-effects of fluvoxamine (100-300 mg/d) (n = 24) and maprotiline (50-150 mg/d) (n = 24) were compared in moderately depressed outpatients with DSM-III Major Depression (n = 22) or Dysthymic Disorder (n = 26). Efficacy was measured by means of the Hamilton Depression Rating Scale, the Zung Depression Selfrating Scale, and a Clinical Global Impression of Severity Scale. Side-effects were evaluated by an Adverse Event Inventory and a Psychosomatic Symptom Scale. A statistically significant improvement was achieved in both treatment groups but success rates were modest: in both groups, 29% of the patients achieved a clinically significant improvement after six weeks of treatment. After six weeks of treatment, no difference in efficacy was found between fluvoxamine and maprotiline. Nausea was the most common complaint in the fluvoxamine group, while in the maprotiline group, it was dry mouth and constipation. One maprotiline-treated patient developed a convulsive attack.

Results are presented of the first double-blind, placebo-controlled trial of a novel antidepressant venlafaxine, which preclinically has demonstrated serotonin, norepinephrine, and dopamine reuptake inhibiting effects. Sixty outpatients meeting DSM-III-R criteria for major depression were randomized to receive 6 weeks of treatment with one of three fixed doses of venlafaxine--25 mg three times a day, 75 mg three times a day, or 125 mg three times a day--or placebo. Significant improvement was observed in depression scores at all doses, with the high dose resulting in earlier improvement, by week 2. For the combined venlafaxine treatment groups, 68% achieved a moderate or marked improvement on the Clinical Global Impression scale, compared with only 31% for the placebo group. Venlafaxine was well tolerated, and nervousness, sweating, and nausea were the only adverse effects observed more frequently with drug compared with placebo.

The safety and efficacy of nortriptyline and fluoxetine were compared in a double-blind, randomized, multicenter 5-week trial involving 205 outpatients with acute major depression of moderate severity. Seventy-two nortriptyline and 84 fluoxetine patients completed at least 2 weeks of medication and were included in the efficacy analysis; all patients were evaluated for side effects. Average total scores on the Hamilton Rating Scale for Depression (HAM-D) for both treatment groups declined from 22-23 at baseline to 11.5 at the conclusion of the 5-week period. At Week, 5, 71% of nortriptyline patients and 65% of fluoxetine patients were much or very much improved. Fluoxetine was associated more frequently with nausea (p less than .05), while nortriptyline was associated more frequently with dry mouth (p less than .05). These results are discussed in the context of selecting between nortriptyline and fluoxetine for a particular depressed patient.

The antidepressant efficacy and adverse-effects of rolipram (a dialkoxyphenyl-2-pyrrolidone) were compared to those of amitriptyline in the treatment of depressive illness requiring hospital admission in a double-blind study. Fifty patients meeting DSM-III criteria for Major Depression whose scores on the Hamilton Rating Scale for Depression (HRSD) remained above 17 after 5 to 7 days on placebo were randomly allocated to either treatment. The rate of recovery in those patients treated by amitriptyline was substantially greater than in those patients treated by rolipram. Twice as many patients dropped out of treatment by rolipram because of lack of efficacy or adverse-effects compared with patients treated by amitriptyline. Rolipram produced fewer adverse-effects attributable to cholinergic blockade, but more nausea. We conclude that amitriptyline is more effective than rolipram in the treatment of depressed hospital in-patients.

The authors employed a double-blind, placebo-controlled design to investigate the effectiveness of fluvoxamine versus imipramine in 54 outpatients with moderate major depression. Fluvoxamine proved superior to placebo but not to imipramine on the Hamilton Rating Scale for Depression and the Montgomery and Asberg Depression Rating Scale. Nausea and hyperarousal were the most common side effects in the fluvoxamine-treated patients.

One hundred forty outpatients with major depression were admitted to an 8-week, placebo-controlled, double-blind study of buspirone. Entry criteria included a Hamilton Rating Scale for Depression (25-item [HAM-D]) score of greater than or equal to 18 and a Hamilton Rating Scale for Anxiety (HAM-A), score of greater than or equal to 18. A flexible dose schedule ranging from 5-90 mg/day was employed. The mean dose of buspirone was 41-54 mg/day from Week 2 to the end of the study. Sixty-four percent of buspirone patients and 50% of placebo patients were melancholic; 64% of buspirone patients and 74% of placebo patients discontinued treatment before the end of the study. Extender data analysis showed that buspirone patients had significant (p less than .05) HAM-D score reductions compared with the placebo group at Weeks 2, 3, 4, and 6. The HAM-D retardation factor trended toward significance over placebo at Weeks 3, 4, and 6. HAM-D change scores for the subgroup of melancholic patients taking buspirone were significantly (p less than .02) better than those of the placebo-treated melancholic subjects at Weeks 2, 3, 4, and 6. Most other efficacy parameters also favored the buspirone-treated group over the placebo-treated group. The most common adverse experiences for the buspirone group were CNS effects (74% in the buspirone group vs. 21% in the placebo group) and gastrointestinal effects (55% in the buspirone group vs. 37% in the placebo group). Side effects consisted of dizziness, light-headedness, nausea, and headache. No serious or unexpected adverse effects occurred.(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty nine patients admitted with a diagnosis of psychogenic vomiting were classified into five patterns of vomiting: continuous, habitual postprandial, irregular vomiting, nausea, and self induced. The psychiatric disorders related to the onset of vomiting were either a major depression or a conversion disorder. Continuous vomiting was usually due to a conversion disorder, while in many cases of habitual postprandial and irregular vomiting, major depression was observed. The patients' psychiatric disorders and vomiting patterns often changed during the clinical course. Assessing the psychiatric problems and vomiting patterns is important in the diagnosis and treatment of psychogenic vomiting.
