Psychosomatic aspects of hyperprolactinemia.

A review of some recent studies on the psychosomatic aspects of hyperprolactinemia is presented. Women seem to be more prone to suffer from the behavioral effects of prolactin than males. Women with hyperprolactinemic amenorrhea rated themselves significantly more hostile, more depressed and more anxious than women with amenorrhea only and other control groups. Hyperprolactinemic males did not rate themselves more hostile and depressed than matched controls. Psychological distress and hostility appear to remit upon treatment with bromocriptine. Postpartum patients matched for prolactin levels with hyperprolactinemic women showed significantly less depression and anxiety but about the same levels of hostility. Hostility, depression and loss of libido may coexist in the same hyperprolactinemic patient but they may be also present independently.

Italian validation of the Symptom Rating Test (SRT) and Symptom Questionnaire (SQ).

Two self-rating scales of psychological distress, the Symptom Rating Test (SRT) and the Symptom Questionnaire (SQ), have been validated in translations in Italy. They were administered in several studies to psychiatric patients (neurotics and depressives), matched controls, and patients suffering from various organic illnesses (dermatologic disorders, hypertension, secondary amenorrhea and patients undergoing amniocentesis). The SRT and the SQ sensitively discriminated between psychiatric patients and normals, between different levels of psychological distress in several of the somatic illnesses, and detected significant changes in the psychological status of patients participating in medical procedures such as amniocentesis. The scales were found to be useful in research in psychiatry and psychosomatic medicine. The findings suggest that the Italian translations are valid and sensitive scales of distress and can apparently be used as effectively in research as the original. They are likely to be of value in cross-cultural research in Canada. Both scales may be helpful in the psychological assessment of Italian immigrants in North America and Australia, especially in those whose English is poor.

The enzyme-linked immunosorbent assay for detection of the antispermatozoal antibodies.

An immune-enzymatic method was developed for the determination of antispermatozoal antibodies. Sera of 94 infertile patients were studied with the enzyme-linked immunosorbent assay (ELISA). Twelve patients were positive for antispermatozoal antibodies. Forty-six of these patients were studied also with the gelatin agglutination test (GAT). Eight sera were positive in the ELISA and nine in the GAT. With ELISA, immunoglobulin classes can be demonstrated; in fact, nine of our patients were positive for IgG and three for IgM. In all patients the IgA titer was less than 1:16. In addition, 61 seminal fluid specimens were studied by ELISA, and 7 were positive. The serum and seminal fluid of 12 patients were simultaneously studied. Seminal fluid was positive in only three patients, serum was positive in four, whereas serum and seminal fluid were both negative in five. This study illustrates that ELISA is apparently less sensitive than GAT; however, it is certainly more practical and an easier method for antibody research in sera and in seminal fluid.

Depression and hostility in hyperprolactinemia.

1. Patients with hyperprolactinemia offer a unique opportunity to investigate the effects of prolactin on psychological states. Women with hyperprolactinemic amenorrhea rated themselves significantly more hostile, more depressed and more anxious than women with amenorrhea only and normal women. 2. The hyperprolactinemic patients were compared with a group of post-partum (7th day) women, matched for sociodemographic variables and prolactin levels. The post-partum women showed significantly less depression and anxiety than those with hyperprolactinemic amenorrhea but about the same levels of hostility. 3. Hyperprolactinemic males did not rate themselves more hostile and depressed than matched controls.

Psychological correlates of hyperprolactinemia in males.

In a previous study with hyperprolactinemic female patients, self-rated hostility, depression and anxiety were significantly higher than in other female patients. The study was repeated in hyperprolactinemic males, using the same psychological assessments. Hyperprolactinemic males were significantly more anxious but did not differ significantly in hostility and depression from other male patients. The findings support the view that the psychological effects of high serum prolactin levels depend in part on interactions with gonadal hormones.

Andropause: incidence and pathogenesis.

One hundred forty-five male volunteers, 60 to 91 years old, without any hepatic, renal, or metabolic pathology, and not under any steroid therapy for at least 1 year were studied. Plasma luteinizing hormone (LH), Follicle Stimulating hormone (FSH), Testosterone (T), 17-beta-Estradiol (E2), Androstenedione (A), Maximal increase (MI) of LH and FSH after luteinizing hormone releasing hormone (LHRH) (50 gamma iv), and pulsations (P) of LH and FSH over a 3 hr period were measured by radioimmunoassay (RIA). The patients were divided in four groups according to LH and T levels. Group I: (46% of our subjects) showed no signs of hypogonadism with normal LH, T, E2, A, MI of LH and FSH, and normal P-LH, P-FSH. Group II: (15%) with high LH but normal T, showed high FSH, MI-LH, MI-FSH, P-LH, and P-FSH, but normal A and E2. Group III: (22%) with classical signs of hypergonadotropic hypogonadism (high LH and low T) showed high FSH, MI-LH, MI-FSH, and P-FSH, normal P-LH and E2, but low A. Group IV: (16.5%) with signs of hypogonadotropic hypogonadism (low LH and low T) had also low MI-LH, MI-FSH and A, but normal FSH, P-LH, P-FSH, and E2. Contrarily to menopause in women, andropause is not an obligatory event in men, and when it does occur, its pathogenesis and hormonal aspects are very variable.

Male hypogonadism in aorto-iliac arteriopathies.

In 43 patients affected by aorto-iliac arteriopathies, gonadotropins, testosterone, androstenedione serum levels were measured to verify the presence of a testicular alteration secondary to ischemia. Important signs of testiculopathies (increased gonadotropins and decreased testosterone serum levels) were observed in patients with flow alteration of the internal spermatic artery and in patients with obstructions of the common iliac. Plasma androstenedione levels were not decreased while the A/T ratio was increased in hypotestosteronemic patients. Ischemia might determine a functional block of 17 beta reductase enzyme, necessary to convert androstenedione to testosterone. The impotentia coeundi, which affected about 50% of our patients is not related to testosteronemia.

Depression hostility and anxiety in hyperprolactinemic amenorrhea.

In order to evaluate the relationship of psychological distress to hyperprolactinemia, 20 patients with secondary amenorrhea were evaluated by a semi-structured research interview and administered the Kellner Symptom Questionnaire. Group A (10 patients with amenorrhea and hyperprolactinemia) reported significantly more symptoms of depression, hostility and anxiety than group B (10 patients with amenorrhea and normal basal levels of plasma prolactin). Both groups were significantly more anxious, depressed and reported more somatic symptoms than a normal control group (n = 10). 6 of the 10 patients in group A reported decrease in libido, while this was found only in 1 of the 10 patients of group B. The findings suggest that the syndrome of depression, hostility and anxiety in a woman complaining of amenorrhea, especially if associated with decreased libido and galactorrhea, can be a manifestation of hyperprolactinemia.

Immunological and clinical study of patients after spermatic cord torsion.

We studied 25 patients with spermatic cord torsion occurring after puberty. The elapsed time between the onset of symptoms and observation varied from 6 months to 7 years. We evaluated the semen of these patients and found that the number of spermatozoa was lower in patients with an atrophic testis (13 patients) than in those with a normal testis or, in those with torsion treated by orchidectomy. Moreover, the number of spermatozoa was lower in patients who had torsion for more than 2 years before being checked (12 patients) than in patients who had a more recent torsion (13 patients). Agglutinating antibodies were present in 20% of the patients but, they are not correlated fertility or sterility. Immunofluorescent antibodies also were not correlated with the changes found by semen analysis. They are not present in patients with a normal testis at the time of observation. On the other hand, immobilizing antibodies were significantly correlated with sterility and, particularly with changes of motility. These data suggest that sterility after spermatic cord torsion is correlated with an autoimmune mechanism. It may occur particularly in those patients with atrophic testes and has a slow onset taking more than 2 years to evolve completely.

Histological study of the removed testes of patients after acute monolateral spermatic cord torsion.

Infertility is frequent in patients after spermatic cord torsion usually when the twisted testis is not removed and becomes atrophic. The mechanism seems to be autoimmune. To see if the atrophic testis may be the source of antigens we carefully examined the histology of atrophic testis of 6 patients. The two patients that had spermatic cord torsion more than 3 years before surgical removal did not show recognizable testicular structures while the other patients that had spermatic cord torsion less than 1 year still showed some spermatogonia in the tubules and some spermatozoa in the epididymis. We think that the surgical removal of the atrophic testis after more than 1 year from the acute episode is of doubtful utility for preventing or blocking the autoimmune phenomenon because testicular antigens are absent and the autoimmune mechanism is able to maintain itself.
