There is now firm evidence that major depression is accompanied by increased baseline activity of the hypothalamic-pituitary-adrenal (HPA) axis, as assessed by means of 24-h urinary cortisol (UC) excretion. Recently, there were some reports that fibromyalgia and post-traumatic stress disorder (PTSD), two disorders which show a significant amplitude of depressive symptoms, are associated with changes in the baseline activity of the HPA axis, such as low 24-h UC excretion. The aim of the present study was to examine 24-h UC excretion in fibromyalgia and PTSD patients compared to normal controls and patients with major depression. In the three patient groups, severity of depressive symptoms was measured by means of the Hamilton Depression Rating Scale (HDRS) score. Severity of fibromyalgia was measured using a dolorimetrically obtained myalgic score, and severity of PTSD was assessed by means of factor analytical scores computed on the items of the Composite International Diagnostic Interview (CIDI), PTSD Module. Patients with PTSD and major depression had significantly higher 24-h UC excretion than normal controls and fibromyalgia patients. At a threshold value of > or = 240 micrograms/24 h, 80% of PTSD patients and 80% of depressed patients had increased 24 h UC excretion with a specificity of 100%. There were no significant differences in 24-h UC excretion either between fibromyalgia patients and normal controls, or between patients with major depression and PTSD patients. In the three patient groups, no significant correlations were found between 24-h UC excretion and the HDRS score. In fibromyalgia, no significant correlations were found between 24-h UC excretion and the myalgic score. In PTSD, no significant correlations were found between 24-h UC excretion and severity of either depression-avoidance or anxiety-arousal symptoms. In conclusion, this study found increased 24-h UC excretion in patients with PTSD comparable to that in patients with major depression, whereas in fibromyalgia no significant changes in 24-h UC were found.

The authors conducted an investigation in four tertiary-care centers to determine if psychiatric comorbidity and psychological variables were predictive of functional impairment in patients with fibromyalgia syndrome (FMS). Seventy-three individuals were administered the Structured Clinical Interview for DSM-III-R, the Rand 36-item Health Survey (SF-36), and multiple self-report measures. The patients with FMS were found to have a high lifetime and current prevalence of major depression and panic disorder. The most common disorders were major depression (lifetime [L] = 68%, current [C] = 22%); dysthymia (10% [C only]); panic disorder (L = 16%, C = 7%); and simple phobia (L = 16%, C = 12%). The self-report scales revealed significant elevations in depression, anxiety, neuroticism, and hypochondriasis. Functional impairment on all measures of the SF-36 was severe (e.g., physical functioning = 45.5 and role limitations due to physical problems = 20.0). Stepwise multiple-regression analysis revealed that current anxiety was the only variable that predicted a significant proportion of the variance (29%) in SF-36 physical functioning. Thus, in this multicenter study, the persons with FMS exhibited marked functional impairment, high levels of some lifetime and current psychiatric disorders, and significant current psychological distress. Current anxiety level appears to be an important correlate of functional impairment in individuals with FMS.

Depression and fibromyalgia (FM) share common symptoms, indicating a close relationship between both disorders. FM patients frequently present symptoms of major depression. Genetic epidemiological studies show that genetic transmission is one important component. Molecular genetic studies are on the way; the serotonin transporter promoter gene seems to be associated with neurotic anxiety and FM. Biochemical studies related to the serotonin and norepinephrine neurotransmission are disturbed in both disorders. This view is supported by the response to treatment with antidepressants.

Psychosocial distress and psychological abnormality occurs frequently in fibromyalgia patients. Patterns of decreased levels of education, and increased rates of divorce, obesity, and smoking have been noted in clinical and epidemiological studies. Links to physical and sexual abuse have been noted as well. Major depression as well as increased rates of depression, anxiety, and somatization are also commonly found in fibromyalgia.

Venlafaxine is a medication available by prescription in the U.S. both in an immediate release and an extended release formulation. Preclinical studies indicate it has the effect of potently blocking the serotonin and norepinephrine transporters. Venlafaxine is approved by the FDA for the treatment of major depressive disorder and generalized anxiety disorder. Suggestive evidence, mostly from open label case series, indicates efficacy of venlafaxine in several other conditions including panic disorder, social anxiety disorder, obsessive compulsive disorder, trichotillomania, ADHD, chronic pain, and fibromyalgia. The limited evidence supporting efficacy in these conditions is reviewed. Additional randomized clinical trials with placebo controls are indicated.

The complex and intimate interactions between the sleep and immune systems have been the focus of study for several years. Immune factors, particularly the interleukins, regulate sleep and in turn are altered by sleep and sleep deprivation. The sleep-wake cycle likewise regulates normal functioning of the immune system. Although a large number of studies have focused on the relationship between the immune system and sleep, relatively few studies have examined the effects of sleep deprivation on immune parameters. Studies of sleep deprivation's effects are important for several reasons. First, in the 21st century, various societal pressures require humans to work longer and sleep less. Sleep deprivation is becoming an occupational hazard in many industries. Second, to garner a greater understanding of the regulatory effects of sleep on the immune system, one must understand the consequences of sleep deprivation on the immune system. Significant detrimental effects on immune functioning can be seen after a few days of total sleep deprivation or even several days of partial sleep deprivation. Interestingly, not all of the changes in immune physiology that occur as a result of sleep deprivation appear to be negative. Numerous medical disorders involving the immune system are associated with changes in the sleep-wake physiology--either being caused by sleep dysfunction or being exacerbated by sleep disruption. These disorders include infectious diseases, fibromyalgia, cancers, and major depressive disorder. In this article, we will describe the relationships between sleep physiology and the immune system, in states of health and disease. Interspersed will be proposals for future research that may illuminate the clinical relevance of the relationships between sleeping, sleep loss and immune function in humans.

The pineal hormone melatonin is the mediator of external light to physiologic adaptation to day and night rhythms, it regulates reproduction in animals but attempts to utilize melatonin in women for contraception have failed. Melatonin seems to be the natural hormone to facilitate sleep in insomniac patients and causes no hang over. When applied together with benzodiazepine it allows reduction of benzodiazepine without withdrawal effects. It should be applied 2 h before sleeping time in doses between 3 and 5 mg. Melatonin acts via the gamma-aminobutyric acid- and benzodiazepine receptor explaining its success in treatment of seizures in children and in adults. Constant application of benzodiazepine reduced the production of natural melatonin in rats, supporting the evidence that long-term application of benzodiazepine in humans does not restore sleeping habits but reduces natural sleeping habits even more. Low melatonin levels were seen in bulimia or neuralgia and in women with fibromyalgia; replacement reduced pain, sleeping disorders, and depression in fibromyalgia and bulimia. Melatonin profiles are a diagnostic tool to distinguish between several forms of depression, like major depression, winter depression (SAD), unipolar depression, delayed sleep phase syndrome (DSPS). In patients with a major depression success with antidepressants correlated with an increase in their melatonin profiles but only patients suffering from DSPS can be successfully treated with melatonin. In perimenopausal women melatonin administration did produce a change in LH, FSH and thyroid hormones. Some oncostatic properties are supported by cell culture work and studies in animals. In Nordic countries indigenous people suffer less from breast and prostate cancer, winter darkness seems to protect. The supposedly increased melatonin levels created the 'melatonin hypothesis'. Epidemiological studies did show that blind people indeed have half the rate of breast cancers, supporting the hypothesis. Controversial results concerning melatonin and insulin resistance and glucose tolerance have been published. In postmenopausal women application of melatonin reduced glucose tolerance and insulin sensitivity. Pregnant women should avoid melatonin, since its teratogenic effect is not known. Patients suffering from non-hormone dependent tumors, like leukemia, should avoid melanin, since tumor growth was promoted in animal experiments. It can be expected that melatonin will receive wide consideration for treatment of sleeping disturbances, jet lag, and fibromyalgia once an oral formulation becomes available in Europe.

The fibromyalgia syndrome (FMS) is the most frequent cause of chronic widespread pain. In this review, we summarize the state of the art on the syndrome and its pathophysiology, with an emphasis on identifying bases for the development of novel therapies. Toward this end, the anatomy and physiology of pain pathways are summarized, followed by a review of the altered biology of pain processing, neurotransmitter function, and neuroendocrine systems in FMS. The categories of drugs currently employed to treat the disorder are detailed, along with a critical review of the literature supporting such use. Throughout the article, FMS is compared with and related to both major depressive disorder and neuropathic pain, conditions that may share some common biological processes with FMS but for which new drug discovery efforts are significantly more active due to the more established nature of these diagnoses.

Major depressive disorder (MDD) and anxiety disorders such as generalized anxiety disorder (GAD) are often accompanied by chronic painful symptoms. Examples of such symptoms are backache, headache, gastrointestinal pain, and joint pain. In addition, pain generally not associated with major depression or an anxiety disorder, such as peripheral neuropathic pain (e.g., diabetic neuropathy and postherpetic neuralgia), cancer pain, and fibromyalgia, can be challenging for primary care providers to treat. Antidepressants that block reuptake of both serotonin and norepinephrine, such as the tricyclic antidepressants (e.g., amitriptyline), have been used to treat pain syndromes in patients with or without comorbid MDD or GAD. Venlafaxine, a serotonin and norepinephrine reuptake inhibitor, has been safe and effective in animal models, healthy human volunteers, and patients for treatment of various pain syndromes. The use of venlafaxine for treatment of pain associated with MDD or GAD, neuropathic pain, headache, fibromyalgia, and postmastectomy pain syndrome is reviewed. Currently, no antidepressants, including venlafaxine, are approved for the treatment of chronic pain syndromes. Additional randomized, controlled trials are necessary to fully elucidate the role of venlafaxine in the treatment of chronic pain.

The effect of electroconvulsive therapy (ECT) on depression and other symptoms of fibromyalgia was studied in a prospective 3-month trial in 13 patients with fibromyalgia and concomitant depression. All the patients met the DSM-IV diagnostic criteria for Major Depressive Disorder and fulfilled the American College of Rheumatology diagnostic criteria for fibromyalgia. The Montgomery and Asberg Depression Rating Scale (MADRS) and the clinical global impression scale (CGI) were used to assess the severity of depression and the clinical change of the patients. The fibromyalgia impact questionnaire (FIQ) was used to evaluate the severity of the fibromyalgia symptoms. The intensity of pain was evaluated using a 6-point scale (0=no pain, 5=very severe pain), and tender point palpation. All assessments were performed at baseline and at follow-up visits, which took place one week, one month and three months after ECT. There was a significant improvement in depression after ECT according to MADRS. Using CGI, six patients were much or very much improved, while four patients were minimally improved and three patients had no change. There was significant improvement in four out of ten FIQ item scores, "feel good", "fatigue", "anxiety" and "depression". No significant change was found in the FIQ item scores "physical function", "pain", "stiffness" and "morning tiredness" or number of tender points and self-reported pain. We conclude that ECT is a safe and effective treatment for depression in fibromyalgia patients, but has no effect on the pain or other physical symptoms of these patients.
