[Autonomic neuropathy in somatization disorders]

AIM: We conducted a study to investigate whether patients with somatization disorder show abnormal values in autonomic testing, especially in the central baroreceptor sensitivity. PATIENTS AND METHODS: Seventy-one patients were included. All had a diagnosis of somatization disorder (ICD-10, F45.0). Psychometric testing was performed by means of validated questionnaires (STAI, STAXI, FPI, GBB, ADS, SOMS, SCL-90-R). Autonomic regulation was analyzed by international standards using frequency spectral calculation by fast Fourier transformation. Thereby 3 different groups were detected: 12 patients with a baroreceptor sensitivity (BRS) of less than 3.0 ms/mm Hg, 20 patients with normal BRS (> 9.0 ms/mm Hg), and an in-between group (n = 39) with intermediate BRS. Controlling for age, a covariance analysis was calculated. RESULTS: The two extreme groups showed no difference in psychometric testing. However, significant differences were discernible in spectral values of mid-frequency-band (p < 0.05) in a covariance analysis with age as covariate. Equally the 24 h blood pressure determination showed significantly higher values for the group with BRS < 3.0 ms/mm Hg (p < 0.05 to 0.001). CONCLUSIONS: In a high percentage (17 %) of patients diagnosed to have somatization disorder autonomic dysregulation becomes apparent and is accompanied by increased blood pressure. Therefore it doesn't seem accurate to overlook concomitant organic lesions in somatization disorders despite patients lacking overtly clinical signs but suffering from various unspecific symptoms.

Systemsklerose

Die Systemsklerose ist charakterisiert durch autoimmune Phänomene und eine progressive Fibrose. Klinische Charakteristika sind neben der Sklerodermie ein ausgeprägtes Raynaud-Phänomen und Abnormitäten der Nagelfalzkapillaren, ferner pulmonale, renale, kardiale und intestinale Veränderungen. In der Regel wird eine diffuse von einer limitierten Form unterschieden. Die diffuse Form führt zu einer Sklerose des gesamten Integumentes, ist assoziiert mit dem Auto-antikörper Scl-70 und zeichnet sich durch eine rasche Krankheitsprogression aus. Die limitierte Form betrifft die distalen Extremitäten und das Gesicht, ist assoziiert mit dem centromer Autoantikörper und führt schleichend, über mehrere Jahre zu viszeralen Problemen. Neue therapeutische Möglichkeiten können zu einer besseren Lebensqualität verhelfen und verpflichten zu einem systematischen Krankheitsmonitoring.

Naturalistic study on the effectiveness of psycho-oncological interventions in cancer patients and their partners

BACKGROUND There is evidence for the efficacy of psycho-oncological interventions (POI) in randomized controlled trials for cancer patients. Our objective was to explore, under naturalistic conditions (using propensity score matching), whether POI are effective to decrease anxiety, depression, distress and overall psychopathological symptoms within cancer patients and their partners. METHODS This study was conducted in the Oncology and Hematology Center of a University clinic in Switzerland with a group of 186 patients and 117 partners. Outcome measures of mental health were the Hospital Anxiety and Depression Scale and the Symptom Checklist (SCL-9-K). Repeated-measures ANOVAs were used to analyze change over time and group effects between individuals with POI vs. without POI. RESULTS Highly distressed patients and their partners participating in POI reported better mental health over time. Among moderately distressed patients, a decrease over time emerged in depression and distress independent of POI. No effectiveness of POI could be demonstrated in moderately distressed patients and partners. CONCLUSION Most of the highly distressed patients receive additional POI and therefore conclusions about the efficacy of POI are difficult. For moderately distressed individuals, POI as implemented in Switzerland does not improve mental health in such patients and their partners, which may be caused by very time limited POI treatments. Studies with more intense POI treatments are needed.
