Six-year outcome for cognitive behavioral treatment of residual symptoms in major depression.

OBJECTIVE: The authors' goal was to determine whether cognitive behavioral treatment of residual symptoms of depression might have a significant effect on relapse rate. METHOD: A 6-year follow-up assessment was conducted of 40 patients with primary major depressive disorder who had been successfully treated with antidepressants and were randomly assigned to either cognitive behavioral treatment of residual symptoms or standard clinical management. RESULTS: Ten of the patients (50%) in the cognitive behavioral treatment group and 15 (75%) in the standard clinical management group relapsed. The difference did not attain statistical significance. When multiple relapses were considered, patients in the cognitive behavioral treatment group had a significantly lower number of depressive episodes than those in the standard clinical management group. Patients responded to the same antidepressant drug used in the index episode; in two cases (4%), resistance occurred. CONCLUSIONS: The protective effects of cognitive behavioral treatment that were evident at 4-year follow-up faded afterward. Cognitive behavioral treatment of residual symptoms, however, improved the long-term outcome of major depression in terms of total number of episodes during the follow-up period.

Cognitive behavioral treatment of residual symptoms in primary major depressive disorder.

OBJECTIVE: Cognitive behavioral treatment has been used extensively in the acute phase of depression. The purpose of this study was to determine the applicability and effectiveness of this treatment modality in addressing the residual symptoms of primary major depressive illness. METHOD: The subjects were 40 patients with major depressive disorder who were successfully treated with antidepressant drugs. They were then randomly assigned to either cognitive behavioral treatment or clinical management of residual symptoms. In both subgroups, antidepressant drugs were tapered and discontinued. RESULTS: The group that received cognitive behavioral treatment had a significantly lower level of residual symptoms after drug discontinuation in comparison with the clinical management group. Cognitive behavioral treatment also resulted in a lower rate of relapse (15%) at a 2-year follow-up than did clinical management (35%), although this difference did not reach statistical significance. Most of the residual symptoms were found to have occurred also in the prodromal phase of illness. CONCLUSIONS: This preliminary study points to the potential clinical advantages of cognitive behavioral treatment targeted to the residual symptoms of depression.

Psychosomatic view of endocrine disorders.

This review is concerned with the clinical and research implications of psychosomatic research in endocrinology. A possible role of life events in the pathogenesis of endocrine disease, the psychological distress associated with acute illness, and the issue of quality of life in clinical endocrinology are surveyed. In particular, the psychosomatic aspects of Cushing's syndrome, Addison's disease, hyperthyroidism, hypothyroidism, hyperprolactinemia, acromegaly, growth hormone deficiency, and hirsutism are considered.

Beta-endorphin responses to metyrapone and dexamethasone in depressed patients.

Controversy continues over the characteristics of beta-endorphin secretion in depression. Beta-endorphin plasma levels were measured in 30 drug-free male patients with a DSM-III-R major depressive disorder and 21 healthy controls. Depressed patients displayed significantly lower beta-endorphin plasma levels in baseline conditions, after the single dose metyrapone test, and after the dexamethasone suppression test. The activation of hypothalamic-pituitary-adrenal (HPA) axis in depression might be due, at least in part, to low levels of beta-endorphin. These results suggest that HPA axis dysregulation in depression may involve peptides other than ACTH.

Effects of metyrapone and dexamethasone upon pro-gamma-MSH plasma levels in depressed patients and healthy controls.

There is current controversy over the mechanisms underlying hypothalamic-pituitary-adrenal (HPA) axis hyperactivity in depression. Pro-gamma-melanocyte-stimulating hormone (MSH), a portion of the N-terminal region of pro-opiomelanocortin, has been shown to act synergistically with adrenocorticotropic hormone (ACTH) in stimulating corticosteroid secretion both in vitro and in vivo. Pro-gamma-MSH and ACTH plasma levels were measured in 30 drug-free male patients with a DSM-IIIR major depressive disorder and 21 healthy controls. The baseline levels were similar in the two groups. After single-dose metyrapone stimulation, both hormones increased, but pro-gamma-MSH was significantly higher in control subjects than in depressives. After overnight 1-mg dexamethasone, ACTH was significantly less suppressed in depressives than controls. These results suggest that HPA axis dysregulation in depression may involve peptides other than ACTH and be more complex than previously reported.

Effects of metyrapone and dexamethasone on pro-gamma-MSH and ACTH levels in depressed patients.

There is current controversy over the mechanisms underlying hypothalamic-pituitary-adrenal (HPA) axis hyperactivity in depression. Pro-gamma-MSH, a portion of the N-terminal region of POMC, has been shown to act synergistically with ACTH in stimulating corticosteroid secretion in vitro and in vivo. Pro-gamma-MSH and ACTH plasma levels were measured in 30 drug-free male patients with a DSM-III-R major depressive disorder and 21 healthy controls. The baseline levels were similar in the two groups. After single-dose metyrapone stimulation, both hormones increased, but pro-gamma-MSH was significantly higher in control subjects than in depressives. After overnight 1 mg dexamethasone, ACTH was significantly less suppressed in depressives than controls. These results suggest that HPA axis dysregulation in depression may involve peptides other than ACTH and be more complex than previously reported.

Hallervorden-Spatz disease in a psychiatric setting.

Neurodegenerative disorders of sufficient severity to be lethal are also likely to generate psychiatric symptomatology. At times, behavioral changes may predate neurologic manifestations, whereas at other times disturbances in mental status and physical functioning may coexist. In either situation, accurate assessment and appropriate treatment may prove challenging. The case of Hallervorden-Spatz disease reported here illustrates this difficulty; the authors present it to highlight the general issues that often arise in this group of illnesses. In this patient, as well as in three of his relatives, initially subtle neurologic signs were preceded by and then intermingled with significant and sometimes severe symptoms of depression. The authors emphasize the importance of attending to the neurologic symptom picture and family history in order to more appropriately assess the psychiatric manifestations of the disorder. Knowledge of neurodegenerative illnesses, even those as admittedly rare as Hallervorden-Spatz disease, can facilitate accurate and prompt diagnostic assessment, guide treatment strategies (including avoidance of inappropriate interventions), and help to more realistically define outcome expectations.

Nocturnal prolactin and cortisol secretion and recovery from melancholia.

Spontaneous prolactin and cortisol patterns were determined at 20 min intervals over 3 hr during the night in eight patients with melancholia, both during illness and after treatment with amitriptyline. Mean plasma prolactin levels were greater after recovery in the seven patients who responded to treatment. Mean cortisol secretion decreased upon recovery from melancholia, and such changes in two patients paralleled normalization of dexamethasone suppression test responses. The influence of assumptions of lack of interaction on the statistical significance of the analysis of variance with repeated measures for prolactin and cortisol values was evaluated.

Major depression associated with endocrine disease.

The discovery of specific behavioral effects of several neuropeptides and the expanded appreciation of a wide range of endocrine disturbances in depressive illness have recently renewed interest in the nature of the relationship between mood and endocrine changes. Major depressive disorders are a major and life-threatening complication of Cushing's syndrome, Addison's disease, hyperthyroidism, hypothyroidism and hyperprolactinemic amenorrhea. A treatment primarily directed to the physical condition may be more effective than antidepressant drugs in such organic affective syndromes. The influence of hormonal disturbances in the development of depression in Conn's disease, pheochromocytoma, parathyroid disturbances, SIADH, acromegaly, hirsutism and other endocrine diseases should be individually evaluated. Antidepressant drugs remain the most specific and readily available treatment of major depressive disorders in the setting of endocrine illness.

The dexamethasone suppression and metyrapone tests in depression.

The dexamethasone suppression test (DST) and the metyrapone test (MT), a useful and reliable procedure for assessing the integrity of the hypothalamic-pituitary-adrenal (HPA) axis, were performed in 28 patients suffering from major depressive illness with melancholia. The relationship between the DST and MT appeared to be complex. Patients who failed to suppress cortisol secretion after dexamethasone administration had higher postmetyrapone cortexolone levels and cortexolone/cortisol ratios than suppressors. However, there was a wide range of metyrapone responses in patients exhibiting abnormal DST results. This suggests that failure of adequate suppression after 1 mg of dexamethasone in depressed patients does not necessarily reflect homogeneity in the HPA axis disturbances of such patients.

The metyrapone test in depressed males.

Hyperactivity of the hypothalamic-pituitary-adrenocortical (HPA) axis in depression has received considerable attention, particularly in the now numerous studies utilizing the dexamethasone suppression test. The possibility of HPA axis hypoactivity in this population however has not been similarly explored. To examine this latter possibility, the metyrapone test, a well-established neuro-endocrine assay for determining pituitary reserve, was administered to ten endogenously depressed males and ten matched controls. Consistent with the findings of an earlier study on ten female depressives, one of the depressed males but none of the controls showed clear evidence of HPA axis hypoactivity. This suggests that HPA axis dysfunction in depressives may be more complex than originally anticipated. This finding also has implications for the psychiatric symptomatology classically associated with such illnesses as Addison's disease.

Case report of prolactin and bipolar illness: a longitudinal study.

A longitudinal and naturalistic study of nine bipolar patients attending a lithium clinic during a six-month period was undertaken. Prolactin plasma levels and psychiatric symptoms were evaluated bi-weekly. Wide interindividual and intraindividual fluctuations were observed both in prolactin levels and psychiatric symptoms. The relationship between prolactin and affective episodes was found to be complex. In a few instances, sharp prolactin changes preceded behavioral modifications. Bipolar disorders, even if treated, appeared to be unstable conditions, from both the phenomenological and neuroendocrinological viewpoints.

The metyrapone test in schizophrenic patients and healthy subjects.

The metyrapone test, a useful and reliable procedure for assessing hypothalamic-pituitary-adrenocortical (HPA) axis function, was applied to schizophrenic patients and healthy controls. 4 out of 18 patients had subnormal responses to metyrapone whereas there were no such cases in the 22 control subjects. 1 schizophrenic patient and 3 control subjects had high normal responses to metyrapone. The relationship with the dexamethasone suppression test was found to be complex. These preliminary results suggest that the HPA axis activity patterns in psychiatric illness may be more complicated than previously reported.

The metyrapone test in affective disorders and schizophrenia II. Changes upon treatment.

The metyrapone test was applied to groups of patients suffering from major depressive illness with melancholia, mania or schizophrenia, before and after treatment. There were interesting individual correlations between post-metyrapone cortexolone values, cortexolone/cortisol ratios and clinical improvement in depressives. Two patients who had exhibited abnormal metyrapone responses displayed a normalization of post-metyrapone cortexolone values upon clinical improvement, whereas the opposite trend was observed in a patient who did not improve and in another who became manic. These preliminary results may indicate that abnormal metyrapone responses in depression are state dependent.

The metyrapone test in affective disorders and schizophrenia.

The metyrapone test was applied to patients suffering from major depressive illness with melancholia, from mania, and from schizophrenia. Hypoactivity of the HPA axis as assessed by the test appears to occur infrequently in affective disorders and schizophrenia. High normal or exaggerated responses to metyrapone, as observed in Cushing's disease, appear to be correlated to DST non-suppression in melancholia.

The metyrapone test in manic patients and healthy subjects.

The metyrapone (Metopiron) test (MT), a useful and reliable procedure for assessing hypothalamic-pituitary-adrenal (HPA) axis function, was applied to manic patients and healthy subjects. Three out of 11 patients had high normal responses to metyrapone, as observed in patients with Cushing's disease. One patient exhibited a subnormal response to metyrapone, as occurs in patients with adrenal insufficiency. No such abnormalities were detected in 11 matched healthy control subjects. These preliminary results suggest that the HPA axis activity patterns in mania may be more complex than previously reported.
