The relationship among therapeutically induced affective arousal, depressive symptoms, pain and beta-endorphin levels were explored on 6 patients with chronic, active rheumatoid arthritis. An ABA, n of 1 study methodology was utilized, replicated 5 times. This procedure allowed the analysis of individualized changes across time in response to the therapeutic regimen. The results indicated that the treatment regimen activated the beta-endorphin system, particularly during the early and late phases of treatment. However, beta-endorphin response had little effect on reports of subjective pain. Depressive symptoms were affected positively by the treatment but were not strongly correlated to the beta-endorphin response. The results suggest that pain and depression represent independent systems and that beta-endorphin levels serve more as stress markers than analgesics in chronic, organic pain.

Non-suppression of the hypothalamic-pituitary-adrenocortical activity on the dexamethasone suppression test was found in 27/115 patients who were referred to consulting psychiatrists in the Psychiatric Outpatient Clinic of Turku University Central Hospital and in the Rehabilitation Research Centre because of unspecific chronic pain complaints. Depressive symptoms in the patients were identified by the Research Diagnostic Criteria for definite or probable endogenous and non-endogenous depressive disorders. The cortisol levels after dexamethasone suppression were significantly higher in endogenous than in non-endogenous patients and it uncovered masked depression in some complex patients. However, nonsuppression in the dexamethasone suppression test was not specifically associated with the pain-prone disorder, which was further characterized by the factor models of the Hamilton Depression Scale.

The effects of outpatient group cognitive therapy, relaxation training, and cognitive therapy in combination with relaxation training on chronic low back pain and associated physical and psychosocial disability were evaluated and compared. One-hundred and two mildly disabled chronic low back pain patients were assigned randomly to a waiting-list (WL) control condition and the 3 treatments. Patient self-report and observational measures were obtained pretreatment and post-treatment for all conditions, and at 6- and 12-month follow-ups for the treatment conditions. Pain intensity decreased significantly pre- to post-treatment for patients in all 3 treatment conditions, but not the WL condition. Depressive symptoms and disability improved significantly in all conditions (including the waiting list) from pretreatment to post-treatment, with no statistically significant differences among treatments. At both follow-ups, all 3 treatment groups remained significantly improved from pretreatment, with no statistically significant differences between treatments.

Four groups of women were compared in terms of their perimenstrual symptoms, reported menstrual blood loss and period pain, and neuroticism scores: three patient groups were referred to a Gynaecology Outpatient Clinic because of menorrhagia (N = 101), PMS (N = 104), dysmenorrhea (N = 56), and a control group (N = 105). The three patient groups showed considerable overlap in a number of symptoms. This has led us to postulate three factors contributing to perimenstrual complaints: a) a 'timing factor' linked to the ovarian cycle; b) a 'menstruation factor,' associated with the buildup of the endometrium and its shedding; and c) a 'vulnerability factor,' one aspect of which, 'neuroticism,' was measured in this study. Depressive symptoms, which were the most important in leading women to seek help for their PMS, were related to all three factors. Depressive mood changes seemed to be linked to the 'timing factor' but were noticeably worse and more prolonged in women with high neuroticism, heavy bleeding, or severe pain. One premenstrual symptom, food craving, was of considerable interest. This was weakly related to neuroticism, not apparently affected by the 'menstruation factor' and differed in severity between those in the PMS group and the other three groups. It is potentially relevant that both carbohydrate craving and depression are linked to serotonergic changes in the brain, which may prove to be particularly marked in the late luteal phase.

To evaluate the effect of cardiac rehabilitation and exercise training on depression after major cardiac events, we studied 338 consecutive patients in whom a major cardiac event had occurred 4 to 6 weeks previously and who were participating in phase II cardiac rehabilitation consisting of 36 sessions over a 3-month period. Depressive symptoms and other behavioral characteristics and quality-of-life parameters were analyzed by validated questionnaire. Depression was prevalent in patients with coronary heart disease, occurring in 20% of the patients evaluated. At baseline, depressed patients had lower exercise capacity, reduced high-density lipoprotein cholesterol level, and higher triglyceride levels; had lower scores for mental health, energy or fatigue, general health, pain, overall function, well-being, and total quality of life; and had greater scores for somatization, anxiety, and hostility than those of nondepressed patients. After cardiac rehabilitation, depressed patients had marked improvements in depression scores and other behavioral parameters (anxiety, somatization, and hostility) and quality of life. Depressed patients also showed improved exercise capacity, percentage of body fat, and levels of triglycerides and high-density lipoprotein cholesterol. Depressed patients exhibited statistically greater improvements in certain behavioral and quality-of-life parameters than did nondepressed patients. Two thirds of the patients who were initially depressed resolved their symptoms by study completion. In conclusion, depression is reduced in patients with symptomatic coronary heart disease patients enrolled in cardiac rehabilitation. Greater emphasis is needed to ensure that depressed patients are referred to and attend formal cardiac rehabilitation programs after major cardiac events.

Sleep disorders are common and well documented in patients with Parkinson's disease (PD). However, most data on sleep in patients with PD are derived from selected patient populations. This community-based survey evaluated the prevalence of and risk factors for sleep disturbances in an unselected group of 245 patients with PD and two control groups of similar age and sex distribution: 100 patients with another chronic disease (diabetes mellitus) and 100 healthy elderly persons. Nearly two thirds of the patients with PD reported sleep disorders, significantly more than among patients with diabetes (46%) and healthy control subjects (33%). About a third of the patients with PD rated their overall nighttime problem as moderate to severe. The most common sleep disorders reported by the patients with PD were frequent awakening (sleep fragmentation) and early awakening. Sleep initiation showed no significant difference compared with the control groups. Pain and cramps were not more prevalent among the patients with PD, but they were more likely to report sleep disturbed by myoclonic jerks. Use of sedatives was common in all three groups but significantly higher in the PD group than in the healthy elderly. Symptoms of depression and duration of levodopa treatment showed a significant correlation with sleep disorders in the PD group. This community-based study confirms that sleep disorders are common and distressing in patients with PD. The strong correlation between depression and sleep disorders in patients with PD underlines the importance of identifying and treating both conditions in these patients.

Systemic sclerosis (scleroderma) is a rare connective tissue disease that can affect multiple organ systems. Case reports and small treatment studies suggest that pain is significant in scleroderma, but few data speak of the frequency or impact of pain. This study sought to determine the frequency and impact of pain, symptoms of depression, and social network characteristics on physical functioning and social adjustment in patients with scleroderma. One hundred and forty-two scleroderma patients completed measures of pain, depressive symptoms, social network characteristics, physical functioning, and social adjustment. Sixty-three percent reported at least mild pain and 50% reported at least mild levels of depressive symptomatology. Hierarchical regression analyses revealed that pain, depressive symptoms, and employment status (disabled/unemployed vs. not) were significant, independent predictors of physical functioning, together accounting for 37% of the total variance. Pain was the single strongest predictor of physical function, accounting for 20% of the variance. Depressive symptoms, physical functioning, diversity of social network, and employment status were significant independent predictors of social adjustment, together accounting for 63% of the variance. Depressive symptoms were the single strongest predictor of social adjustment, accounting for 26% of the variance. The effects of pain and physical function on social adjustment became non-significant when depressive symptoms were entered into the model, suggesting that symptoms of depression mediate the effect of pain and physical function on social adjustment. These findings indicate that pain is common in scleroderma and that pain and depressive symptoms are significant determinants of physical functioning and social adjustment, two important components of health-related quality of life. Increased attention to effective management of pain and symptoms of depression in scleroderma will likely lead to improved functioning and quality of life.

This study examines and compares the effect of aerobic and resistance exercise on emotional and physical function among older persons with initially high or low depressive symptomatology. Data are from the Fitness, Arthritis and Seniors Trial, a trial among 439 persons 60 years or older with knee osteoarthritis randomized to health education (control), resistance exercise, or aerobic exercise groups. Depressive symptoms (assessed by the Center for Epidemiologic Studies--Depression scale) and physical function (disability, walking speed, and pain) were assessed at baseline and after 3, 9, and 18 months. Compared with results for the control group, aerobic exercise significantly lowered depressive symptoms over time. No such effect was observed for resistance exercise. The reduction in depressive symptoms with aerobic exercise was found both among the 98 participants with initially high depressive symptomatology and among the 340 participants with initially low depressive symptomatology and was the strongest for the most compliant persons. Aerobic and resistance exercise significantly reduced disability and pain and increased walking speed both, and to an equal extent, in persons with high depressive symptomatology and persons with low depressive symptomatology.

We have previously shown that the risk of major depression in patients with malignant melanoma undergoing interferon-alpha (IFN-alpha) therapy can be reduced by pretreatment with the antidepressant, paroxetine. Using dimensional analyses, the present study assessed the expression and treatment responsiveness of specific clusters of neuropsychiatric symptoms over the first three months of IFN-alpha therapy. Forty patients with malignant melanoma eligible for IFN-alpha treatment were randomly assigned to receive either paroxetine or placebo in a double-blind design. Neuropsychiatric assessments were conducted at regular intervals during the first twelve weeks of IFN-alpha therapy and included the 21-item Hamilton Depression Rating Scale, the 14-item Hamilton Anxiety Rating Scale and the Neurotoxicity Rating Scale. Neurovegetative and somatic symptoms including anorexia, fatigue and pain appeared within two weeks of IFN-alpha therapy in a large proportion of patients. In contrast, symptoms of depressed mood, anxiety and cognitive dysfunction appeared later during IFN-alpha treatment and more specifically in patients who met DSM-IV criteria for major depression. Symptoms of depression, anxiety, cognitive dysfunction and pain were more responsive, whereas symptoms of fatigue and anorexia were less responsive, to paroxetine treatment. These data demonstrate distinct phenomenology and treatment responsiveness of symptom dimensions induced by IFN-alpha, and suggest that different mechanisms mediate the various behavioral manifestations of cytokine-induced "sickness behavior."

A purported pathogenic mechanism for the development of fibromyalgia, a medically unexplained syndrome involving widespread pain, is stress and associated psychiatric disorder. The major stressor of recent World Trade Center terrorist attacks provides a natural experiment for evaluating this mechanism. This study sought to determine whether symptoms consistent with fibromyalgia increased post-September 11 and whether exposure to specific terrorism-related events or prior depression predicted symptom increase. In a large community sample of women in the New York/New Jersey metropolitan area (n=1,312), a cohort initially surveyed for pain and psychiatric symptoms before September 11th were recontacted approximately 6 months after the attacks to assess current symptoms and specific terrorism-related exposures. 'Fibromyalgia-like' (FM-L) four-quadrant pain reports consistent with a diagnosis of fibromyalgia were compared at baseline and follow-up. Result showed that FM-L rates did not increase significantly between baseline and post-attack follow-up. Event exposure did not relate to FM-L onset at follow-up, nor did depressive symptoms at baseline interact with event exposure. Depressive symptoms did not predict new onsets better than the extent of their comorbidity with FM-L at baseline. The failure to detect a significant increase in symptoms consistent with a diagnosis of fibromyalgia and the failure of new onsets of such symptoms to be accounted for by exposure to major stressors or prior depressive symptoms suggests that these hypothesized risk factors are unlikely to be of major importance in the pathogenesis of fibromyalgia.
