Lymphocyte subsets in schizophrenic disorders. Relationship with clinical, neuromorphological and treatment variables.

Peripheral blood lymphocyte subsets and serum immunoglobulin levels were assessed in 42 patients and 37 healthy controls. 24 patients were free from neuroleptic medication and 15 had never been treated with neuroleptics. 31 patients had a diagnosis of schizophrenia (DSM-III criteria) and 11 a diagnosis of a disorder of the schizophrenic spectrum. As compared to healthy subjects, the drug naive schizophrenic patient group showed an increase of T suppressor lymphocytes, while the drug-treated schizophrenic group showed an increase of T helper lymphocytes. The drug-treated schizophrenic group differed from the drug naive one relative to a decrease of T suppressor lymphocytes. As compared to healthy subjects, the drug naive spectrum disorder patients showed an increase of absolute number of lymphocytes, while the drug treated spectrum group showed an increase of B lymphocytes. These findings did not correlate with any clinical or neuromorphological variables taken into account.

After a brief reminder of the dual therapeutic aspect (biological and psychological) of spa treatment, the results are presented of a series of psychological reaction tests (McFarland's Psychosomatic Inventory, the Middlesex Hospital Questionnaire, the Rorschach test) given to a randomized sample of 106 patients together with semistructured interviews conducted by two different psychiatrists. The results show substantial agreement between the motivations volunteered verbally and those revealed by the tests and may be summed up as affective rigidity, impoverished emotional life and difficulty in handling body-related anxieties. It is therefore suggested that it would be useful to create a psychosocial spa centre able to provide global treatment adapted to the specific needs of individual users.

Plasma adrenaline and noradrenaline in essential hypertension and after long-term treatment with beta-adrenoreceptor-blocking agents.

1. Plasma adrenaline and noradrenaline were measured in supine and upright positions in 27 essential hypertensive patients and in 12 age-matched control subjects. 2. Plasma adrenaline was markedly increased in a large proportion of patients, compared with control subjects, either in supine or in upright positions, whereas no significant differences were found in plasma noradrenaline. 3. Six hypertensive patients were chronically treated with beta-adrenoreceptor-blocking agents (five with propranolol and one with pindolol). Plasma noradrenaline was not significantly changed in the supine position but was markedly increased on standing in four out of six patients. Plasma adrenaline was decreased in five out of six patients either in suprine or upright positions. 4. These findings support the view that the adrenergic system participates in the mechanism of essential hypertension.

Increased plasma adrenaline concentrations in benign essential hypertension.

Plasma adrenaline, noradrenaline, and dopamine concentrations and plasma renin activity were measured in the supine position and after standing for 10 minutes in 14 patients with sustained benign essential hypertension and in five patients with labile hypertension. Results were compared with values obtained in 11 normotensive control subjects. In controls plasma noradrenaline concentrations increased with age, while plasma adrenaline values tended to decrease with age. No significant difference in mean plasma noradrenaline was found between hypertensive and control subjects, but plasma noradrenaline seemed slightly increased in a proportion of hypertensive patients aged less than 50. Plasma adrenaline was considerably raised in both supine and standing positions in eight patients with sustained hypertension and in two with labile hypertension. Dopamine concentrations and plasma renin activity were similar in all groups studied. The finding of significantly raised plasma adrenaline concentrations in a large proportion of hypertensive patients supports the hypothesis that the activity of the sympathetic nervous system is increased in essential hypertension. Measurement of plasma adrenaline seems to be a more sensitive index of this activity than that of plasma noradrenaline.
