RESUMEN
BACKGROUND: Mental disorders are frequent in hemodialysis (HD) patients. Depression and anxiety along with physical co-morbidity affect quality of life (QOL). Uremia is associated with inflammation and release of cytokines by lymphomonocytes. Inflammatory cytokines are relevant in depression. The aim of this study was to assess the psychological alterations and QOL in HD patients, and to correlate them with pattern of cytokine production. PATIENTS: 30 HD patients and 20 subjects with CKD Stage I-II K-DOQI. Psychometric tests were administered: 1) Hospital Anxiety and Depression Scale (HADS) composed of an anxiety subscale (HADS-A) and a depression subscale (HADS-D); 2) Kidney Disease Quality of Life (KDQOL) modified, including a cognitive function subscale (KDQOL-CF). Whole blood samples collected at beginning of HD session were diluted with RPMI/heparin and incubated for 24 h in presence of lipopolysaccharide (LPS). IL-1Gamma, IL-6, TNF-alpha and IL-10 were assayed on supernatants and results were normalized per number of lymphomonocytes (ng/106 cells). RESULTS: A depressive mood was more frequent in HD patients (50%) than controls (20%, p < 0.0001). No difference for anxiety (HD = 43%, controls = 45%) was observed. QOL score was significantly lower in HD than controls (p = 0.006) and correlated inversely with HADS total, HADS-A and HADS-D (p < 0.0001). Albumin, Kt/V and phosphate were comparable in patients with or without anxiety or depression. Cytokine production was significantly higher in HD patients than controls (IL-1beta p = 0.05; IL-6 p = 0.010; TNF-alpha p < 0.0001; IL-10, p = 0.0019). HD patients with the HADS-A positive for anxiety showed higher IL-6 production (p = 0.026), while IL-1beta levels were not associated with symptoms of depression. KDQOL-CF correlated inversely with levels of IL-6, TNF-alpha and IL-10. CONCLUSIONS: HD patients have symptoms of depression and anxiety that negatively affect QOL. These symptoms are independent of the efficiency of dialysis and nutritional status. On the contrary, IL-6 is linked to the presence of psychological discomfort in these patients.

OBJECTIVE: To evaluate the influence of hormonal status on somatic, psychopathological and mood symptoms in climacteric women. METHOD: 122 postmenopausal women have been evaluated by the PISA-system and P.O.M.S. (Profile of Mood States) to evaluate somatic, psychopathological and mood symptoms in a 3-intervention trial (perimenopausal women, postmenopausal women on replacement therapy, and postmenopausal women without any therapy). RESULT: We found no statistically significant difference among the three groups. A clear trend has however resulted: sex hormones seem to decrease the depressive mood, aggressiveness/anger and sexual dissatisfaction. CONCLUSION: Our results are inconclusive but they suggest that hormones influence some psychological and mood symptoms during the climacterium.

AIMS: It has been previously hypothesized that the adverse outcome observed in depressed patients after myocardial infarction might be due to an imbalance in autonomic nervous system activity. The aim of this study was to define the role of depressive and anxious symptoms in influencing autonomic control of heart rate after myocardial infarction. METHODS AND RESULTS: The SD of RR intervals, baroreflex sensitivity, and depression and anxiety (Zung's scales) were assessed before discharge in 103 patients with acute myocardial infarction; 32 were found to be depressed. Among the patients who were not taking beta-blockers, those with depression had significantly lower SDs of RR intervals and baroreflex sensitivity than did those without depression (96.3 +/- 22.2 ms vs 119.5 +/- 37.7 ms, P =.016; 8.6 +/- 6.2 ms vs 11.8 +/- 6.5 ms/mm Hg, P =.01, respectively). No differences were found when anxiety was considered or when beta-blockers were given. Among the patients not taking beta-blockers, there was a significant correlation between depression levels and both the SD of RR intervals (r = -0.47) and baroreflex sensitivity (r = -0.40). CONCLUSIONS: In patients with myocardial infarction, depression but not anxiety negatively influences autonomic control of heart rate. Beta-blockers modify these influences.

BACKGROUND: In a previous study [Psychother Psychosom 1994;61:199-204] we investigated the relationship between alexithymia, carcinogenesis and immunity in a group of women who were unconscious sufferers from precancerous lesions of the cervix (CIN). The results of this study showed a high level of association between alexithymia and CIN and, an even more interesting fact, between alexithymia and reduced levels of immunity. METHODS: The aim of the present study is to check the results of the previous one by testing a larger group (43 women affected by cervical dysplasia and 67 healthy women) and by the use of a self-administered test for detection of alexithymia, the well-validated Twenty-Item Toronto Alexithymia Scale (TAS-20). RESULTS: The results confirm that women suffering from CIN have higher average TAS-20 ratings (55) than normal women (47.32) and that the level of alexithymia detected in the group of women suffering from dysplasia (42.5%) is higher than that of normal women (12.85%). Moreover, the present study confirms that alexithymic women have lower rates of a number of lymphocyte subsets than non-alexithymic women. CONCLUSIONS: This study fully confirms the results of our previous work and those of a number of other studies: (1) personality might be one of the factors jointly responsible for the outbreak of cancer; (2) the immune system appears to play an important part as a mediator between personality and cancer.

The 20-item Toronto Alexithymia Scale (TAS-20) has been shown in previous research to measure a general dimension of alexithymia with three intercorrelated factors. This study evaluated the reliability and factorial validity of an Italian translation of the TAS-20 in a group of normal adults (N = 206) and in a mixed group of medical and psychiatric outpatients (N = 642). Using confirmatory factor analyses, the previously established three-factor model of the TAS-20 was found to be replicable in both groups. In addition, the Italian TAS-20 demonstrated adequate estimates of internal reliability and test-retest reliability. Although evaluation of the convergent, discriminant, and concurrent validity of the TAS-20 is required in Italian populations, the present results support the use of the Italian translation of the scale for clinical and research purposes.

The purported association between alexithymia and essential hypertension was investigated in a sample of 114 hypertensive patients using the well-validated twenty-item Toronto Alexithymia Scale. Alexithymia was also assessed in a group of 113 general psychiatric outpatients and in a group of 130 normal adults. A rate of 55.3% of alexithymia was found in the hypertensive group compared with significantly lower rates of 32.7% in the psychiatric group and 16.3% in the normal controls. The results support the view that a high prevalence of alexithymia may be found among patients with disorders that were categorized in the past as "classical" psychosomatic diseases. It is hypothesized that a deficit in the cognitive processing and modulation of emotions may leave alexithymic individuals prone to states of heightened sympathetic arousal that are conducive to the development of essential hypertension.

Alexithymia and circulating lymphocyte subsets were studied in 62 women [36 healthy women and 26 women affected by cervical intraepithelial neoplasia (CIN I, II, III) who were not aware of their status] in order to assess a possible relationship between alexithymia, CIN and immunological lymphocytic functions. Alexithymia was estimated by the 20-item Schalling-Sifneos Personality Scale and then correlated with peripheral blood lymphocyte subsets. The results of our study report an association between alexithymia and CIN. Alexithymic women show lower rates of almost all lymphocytic subsets compared to nonalexithymic ones. The difference was also found between alexithymic women affected by CIN and alexithymic women with an unsuspicious Pap smear. On the whole, these preliminary results seem to confirm data reported by other authors who hypothesized that a certain personality trait characterized by emotional inhibition is related to a greater cancer vulnerability. Such relationships might be mediated by certain lymphocytic functions as the result of the alexithymic status. Results reported here need more extensive surveys, in order to control potentially confounding factors related to the personality assessment of the subjects in this study.

The Schalling Sifneos Personality Scale (SSPS) and the Middlesex Hospital Questionnaire (MHQ) have been used in 381 women just before mammography at the Breast Center of the Radiology Institute, University of Bari (Italy). Of the 200 women who accepted to complete the questionnaires 13 were found positive for cancer. Student's t test comparison of the mean SSPS and MHQ scores of the positive for cancer with the negative showed that women with breast cancer have more pronounced alexithymic but not neurotic traits. Our findings suggest that patients with cancer may have something in common with those suffering from so-called psychosomatic pathologies who have a constrained imagination and fantasy and difficulty in verbalizing their emotions. Thus, this study indicates a relationship between alexithymia and cancer.

Polygraphic recordings of nocturnal sleep and hormonal behavior were studied in three male and two female transexual subjects, aged 17 to 26 years, who had required a surgical sex reassignment. The transexual state was assayed by psychological investigations according to the law. All subjects appeared healthy at physical examination and no abnormalities were revealed by basal laboratory data. Chromosomal picture was in accordance with sexual characteristics. Pituitary sella enlargements were excluded by radiographic examination. In each patient two adjustment days were followed by polygraphic recording (EEG,EOG,EMG of chin muscles) of nocturnal sleep and blood drawing for cortisol assay. Blood samples were drawn at 30 minutes intervals for 24 hours, starting from the bedding-time. Hormonal blood concentration were determined by radioimmunoassay. Cosinor method was employed in the analysis of circadian rhythm. In transexual subjects the percentage of sleep intermediate phase, or ambiguous sleep, with reference to total sleep time, was significantly higher than in matched controls.(ABSTRACT TRUNCATED AT 250 WORDS)
