RESUMO
The authors conducted a double-blind prospective study of 39 patients with unipolar endogenous depression who recovered after ECT. Thyrotropin (TSH)-releasing hormone (TRH) tests were performed before and after ECT. Patients were divided into three groups on the basis of their altered TSH response: Persistent remission was predicted for patients in group 1 (N = 15) and relapse was predicted for groups 2A (N = 13) and 2B (N = 11). Patients in groups 1 and 2A received placebo and those in group 2B received amitriptyline for 6 months. Fewer relapses occurred in groups 1 and 2B than in group 2A (p less than .05), showing that relapse can be predicted by the TRH test and prevented by amitriptyline.

Patients with endogenous depression whose depressive episodes were clinically resolved after electroconvulsive therapy were divided into two groups: one in which patients remained well (n = 16) and another in which patients relapsed within 6 months (n = 11). Treatment with amitriptyline for 3 weeks did not affect the median thyrotropin (thyroid-stimulating hormone; TSH) response to thyrotropin-releasing hormone (TRH) in recovered patients, whereas that in relapsed patients was significantly enhanced. The data suggest that amitriptyline affects the TSH response to TRH differently in stably recovered and relapsed patients. If this effect is maintained beyond the 3-week period studied, treatment with amitriptyline will invalidate the predictive value of the TRH test.

The circadian variation of serum thyrotropin (thyroid-stimulating hormone; TSH) was studied in nine patients with endogenous depression before and after recovery. Depressed state did not appear to influence the pattern of TSH. When 2 mg of dexamethasone was administered, serum TSH was significantly reduced for 18 hours, whereafter the effect leveled off. The TSH response to thyrotropin-releasing hormone (TRH) was evaluated 25 hours after the administration of dexamethasone and the response was found to be unchanged.

In 1983 a total of 405 patients received psychiatric supervision in somatic departments in the general hospital. At this supervision, these patients were registered by means of a five-axial diagnostic coding according to the DMS III principle, and this was combined with a quantitative global assessment of the severity of the condition. Reliability testing was undertaken by five supervising physicians with a total of 15 patients. The total number of supervisions constituted one supervision per somatic bed per annum. Women were overrepresented, and medical departments made the greatest use of psychiatric supervision. Reactive conditions dominated parallel with a high relative incidence of alcohol-related conditions. In patients with diagnoses of psychoses, only slight to moderate psychiatric symptoms were encountered. This held true also for personality deviations. 50% of the patients had experienced significant psychosocial stress, but 10% of these were diagnosed as having non-reactive psychoses, 52% of the patients had moderate to pronounced disturbances of social function. Half of the patients supervised in this manner could be investigated or treated in the referring departments. Approximately half of the patients in whom referral to private psychiatric specialists was made did not keep these appointments. Reliability testing in the material shows the employability of the diagnostic armamentarium. All in all, the investigation suggests that extension of the liaison psychiatric service in somatic departments would result in a relative increase in the number of patients who could be treated in the referring department and an increase in the number of psychiatric conditions diagnosed. Establishment of a psychiatric outpatient clinic in the somatic environment appears to be indicated.

Dexamethasone suppression test (DST) and thyrotropin releasing hormone (TRH) stimulation test were performed in 34 patients with endogenous depression. Compared with 33 psychiatric controls (limit of discrimination for serum cortisol of 275 nmol/l = 10 micrograms/100 ml) the specificity of the DST was 91% and the sensitivity was 65%. Compared with 24 healthy subjects the sensitivity of the TRH test was 24%, and the combined sensitivity for the DST and the TRH test was 76%. In contrast to the TRH test the DST showed a significant relationship (r = 0.54, P less than 0.01) to the Hamilton Rating Score. Repeating the tests after clinical recovery parallel changes of the two tests were found in 14 of 19 patients with abnormal DST in the depressed phase. In the remaining five patients the DST normalized, while the TRH test remained unchanged. It is suggested that both the apparent higher diagnostic sensitivity and the higher rate of normalization after clinical recovery of the DST is due to the dependency of the severity of depression.
