Is antidiuretic hormone elevated in psychosis? A pilot study.

Plasma antidiuretic hormone (ADH) measured by radioimmunoassay was higher in acutely psychotic subjects than in acutely anxious nonpsychotic subjects or normal subjects. ADH was not elevated in acutely anxious nonpsychotic subjects. ADH was positively correlated with degree of psychosis. Normal osmolar and volume regulatory mechanisms did not seem responsible for the ADH elevations in the psychotic subjects. Because ADH is both produced in the hypothalamus and can be accurately measured in blood, this substance may prove particularly valuable in the study of psychiatric disorders.

Acute psychosis, increased water ingestion, and inappropriate antidiuretic hormone secretion.

The authors describe three postmenopausal women with agitated psychotic depression, increased water ingestion, and electrolyte values consistent with the syndrome of inappropriate antidiuretic hormone (ADH) secretion. They hypothesize that this clinical triad represents a syndrome reflecting underlying dysfunction of the hypothalamus and limbic system of the brain. The diagnosis of inappropriate ADH in one of the patients was directly confirmed by a recently developed serum radioimmunoassay.

Survey of carnitine content of human semen using a semiquantitative auxanographic method: decreased semen total carnitine concentration in patients with azoospermia or severe oligozoospermia.

A microbiological method, using the carnitine-requiring yeast, Torulopsis bovina ATCC 26014, was developed to identify samples of human semen which contained low levels (less than 250 micron M) of total carnitine. Of 399 semen samples from a male infertility clinic which were tested, 30 (7.5%) were low in carnitine. Of these, 14 were azoospermic and 16 were severely oligozoospermic. Some azoospermic samples (19 = 58%) and severely oligozoospermic samples (51 = 79%) did not give evidence of low carnitine concentrations. These results indicate that decreased total carnitine concentration in semen occurs in certain classes of azoospermic and severely oligozoospermic patients.
