Hostels for the homeless contain many who are disabled by chronic mental illness but have little access to rehabilitation services. One approach to solving this problem might be to measure the needs of hostel residents in a standardized way and use this information as a basis for planning interventions. This study attempted to use the MRC Needs for Care Assessment Schedule to measure the needs of 46 mentally ill residents of Oxford hostels. It aimed to determine if a standardized assessment could be used in these difficult settings and if the needs it identified could form a useful basis for planning future interventions. Although it was possible to use the schedule, and although the pattern of need identified appeared broadly to reflect conditions in the hostels, it was not felt that the information produced was of sufficient quality to assist in planning services. The authors postulate that underlying this deficiency is the failure of the schedule to take sufficient account of the views of staff and residents.

A schedule is described for rating the symptoms of mental illness over a period of time which includes several episodes. The reliability was measured in a study involving six raters. The sources of information required were studied, in 20 patients, by comparing an interview with the patient, a similar interview with an informant and an analysis of the case records. A synopsis of interview and record data are necessary to obtain adequate information about longitudinal psychopathology and ‘lifetime’ diagnosis.

Cross-sectional studies have demonstrated that natural killer (NK) cell activity is reduced in depression. To extend these observations and examine further the association between severity of depressive symptoms and values of NK activity, this study used a longitudinal case control design and assessed NK cytotoxicity at intake and at follow-up 6 months after discharge from the hospital in depressed patients and control subjects. From acute hospitalization to follow-up, depression scores significantly (P < 0·01) decreased following treatment in the depressed patients but did not change in the control subjects. NK activity significantly (P < 0·05) increased from intake to follow-up in the depressives while lytic activity did not change in the controls. At intake NK activity was significantly (P < 0·01) reduced in the depressed patients as compared to values in the controls, while at follow-up cytotoxicity was similar between the two groups. These longitudinal data suggest that a reduction of NK cytotoxicity is temporally associated with the state of acute depression.

Neopterin is a validated marker of the activation of cell-mediated immunity in a variety of disease states. We measured neopterin and creatinine concentrations in the plasma and urine of 22 schizophrenic and 26 depressed patients admitted acutely to hospital, and compared results with those in a large group of normal controls. Neopterin/creatinine ratios were normal in the schizophrenic patients, but significantly elevated in the plasma of depressed patients. In each diagnostic group, the use of psychotropic drugs before admission had no effect on the neopterin ratios observed. Our findings indicate altered cell-mediated immunity in depression.

We report a non-significantly higher growth hormone (GH) response to intravenous clonidine administration (150 μg) in 10 male patients with panic disorder who had never received antidepressant therapy than in 10 matched controls. These results are consistent with data suggesting a normal or increased adrenergic receptor sensitivity in panic disorder patients.
