In the present multicentre double blind study of 428 patients with the irritable bowel syndrome a significant beneficial effect was found on abdominal pain, nausea, sleeplessness and depression by using 50 mg of the antidepressive drug, trimipramine, in the evening, as well as 10 mg three times daily. A significant effect was also recorded for the total score of wellbeing during the treatment period of 6 weeks. No side effects were recorded except tiredness in the morning in some patients during the first two weeks.

Pain is perceived, transmitted, processed and modulated within an extensive network of neurotransmitters and hormones. Despite increasing knowledge about the biologic principles, even on the molecular level, the more we learn about the precise mechanisms of their interactions the more questions arise. It is also pertinent to remember that clinical scientists studying pain modulating pharmacologic agents always have to consider possible placebo effects [57-61]. Most of our knowledge regarding the function of neurotransmitter systems in the CNS has been provided by animal studies. Thus we cannot be sure that they have exactly parallel counterparts in humans. For instance, animal studies suggest an inverse relationship between brain and spinal cord concentrations of substance P. If these observations are converted to an interpretation of human fibromyalgia, low brain-tissue levels of both serotonin and substance P should be expected, while spinal cord serotonin concentrations would be low and spinal cord substance P would be high [1]. There is good evidence that 5-HT, its receptors, and their interactions with other neurotransmitters are essential for nociception and antinociception. The activities of 5-HT receptors can be studied by agonist and in humans especially by antagonist use. But even with a direct spinal application of selective agonists and antagonists, observations may still be confounded by (1) dose, as there can be a dose-dependent activation of different receptor subtypes; (2) type of nociceptive tests (e.g., thermal versus pressure versus chemical models), which may have differences in the way they are regulated; and (3) influences due to effects on temperature, blood flow or motor function. With this potential for variability, it is perhaps not surprising that there is some variability in the results of studies reporting on the effects of various 5-HT agonists and antagonists on nociceptive transmission within the spinal cord [62]. For instance, different 5-HT3 receptor densities could exist in various neuronal systems, one density type being completely inhibited at low concentrations, and the others only at higher concentrations of 5-HT3 receptor antagonists, thus resulting in contrary effects. Finally, the "endogeneous 5-HT tone" may greatly influence agonist and antagonist action. Considering this complexity of serotonin-mediated reactions, it is not surprising that treatment of pain by 5-HT3 receptor antagonists appears to yield inconsistent results. As fibromyalgia is now regarded as a pain amplification syndrome with a broad variety of additional nonpain symptoms, the interrelations are complicated even more. Fibromyalgia associated symptoms (e.g., fatigue, insomnia, and irritable bowel syndrome) can be modulated by 5-HT3 receptor antagonists. From the data evaluated so far, there is evidence that 5-HT3 receptor antagonists provide significant benefit in some fibromyalgia patients. In our practice, the data justify a careful application in clinical use according to the study results. The dosage, route of application, long term adverse reactions and duration of therapy still need to be studied in greater detail. Recently reported adverse events from therapy of irritable bowel syndrome with alosetron [63-67] provide a note for caution before hastily using 5-HT3 receptor antagonists without more studies. One can surmise that, much as the biochemistry of depression has been elucidated by the development of the SSRIs, a greater understanding of the role of 5-HT3 receptor antagonists in treating fibromyalgia patients may provide some insights into disease mechanisms of this enigmatic disorder.

BACKGROUND: There is a need for additional studies of the quality of life (QOL) of elderly depressed subjects with medical comorbidity. METHOD: We conducted an 8-week, open trial of bupropion sustained release (SR) in 18 elderly (60-81 years) subjects with DSM-IV major depressive disorder and one or more serious medical illnesses (e.g., congestive heart failure, type 1 diabetes mellitus, irritable bowel syndrome) with a week-12 follow-up interview. The intent-to-treat method with the last observation carried forward was used to analyze depression and QOL measures. Dosing was initiated at 100 mg once daily and increased at weekly intervals to a maximum of 150 mg twice daily as clinically indicated. RESULTS: Bupropion SR treatment was associated with reductions in Clinical Global Impressions-Severity of Illness scale (p <.0001) score and in the 17-item Hamilton Rating Scale for Depression (HAM-D) total score (p <.0001). QOL as measured by the Medical Outcomes Study Short Form-36 (SF-36) also tended to improve with treatment. The SF-36 "mental health" (p <.01) and "social functioning" (p <.0006) domains improved significantly by week 4. "Vitality" (p <.03) improved significantly by week 12. On the HAM-D, statistically significant improvement was noted on "depressed mood" (p <.0001), "feelings of guilt" (p <.01), "work and activities" (p <.001), "hypochondriasis" (p <.02), and "insomnia" (p <.01) at week 8. The mean dose of bupropion SR at endpoint was 222 mg/day, and the drug was relatively well tolerated. Two subjects dropped out owing to adverse events and 2 owing to other reasons. No drug-drug interactions occurred. CONCLUSION: These data suggest that bupropion SR is well tolerated and may improve depression, insomnia, somatic symptoms, work functioning, and certain quality-of-life measures in elderly depressed subjects with medical disorders. A randomized, placebo-controlled study is warranted to confirm these promising findings.

Koso-san (Xiang-Su-San in Chinese), a Kampo (Japanese herbal) medicine, is used clinically in East Asia for the treatment of depression-like symptoms associated with the initial stage of the common cold, allergic urticaria due to food ingestion, irritable bowel syndrome, chronic fatigue syndrome, insomnia, and autonomic imbalance. However, the antidepressant-like activity of Koso-san has never been evaluated scientifically. In this study, ddY mice subjected to a combination of forced swimming and chronic mild stresses were termed depression-like model mice. The degree of the depression-like state was measured by the animal's duration of immobility using the forced swimming test (FST). Oral administration of Koso-san (1.0 g/kg/body wt./day, 9 days) significantly shortened the duration of immobility of the depression-like model mice in the FST; however, locomotor activity was not affected. Hyperactivity of the hypothalamic-pituitary-adrenal (HPA) axis plays an important role in the pathophysiology of depression. Levels of corticotropin-releasing hormone mRNA expression in the hypothalamus and proopiomelanocortin mRNA expression in the pituitary were significantly increased, and glucocorticoid receptor protein expression in the hypothalamus paraventricular nucleus was downregulated in the depression-like model mice. However, Koso-san ameliorated these alterations to the normal conditions. The results of this study suggest that Koso-san shows the antidepressant-like effect through suppressing the hyperactivity of the HPA axis in depression-like model mice.

There is convincing evidence that acupuncture (AP) is effective for the treatment of postoperative and chemotherapy-induced nausea/vomiting, as well as postoperative dental pain. Less convincing data support AP's efficacy for chronic pain conditions, including headache, fibromyalgia and low back pain. There is no evidence that AP is effective in treating addiction, insomnia, obesity, asthma or stroke deficits. AP seems to be efficacious for alleviating experimental pain by increasing pain thresholds in human subjects and it appears to activate analgesic brain mechanisms through the release of neurohumoral factors, some of which can be inhibited by the opioid antagonist naloxone. In contrast to placebo analgesia, AP-related pain relief takes some time to develop and to resolve. Furthermore, repetitive use of AP analgesia can result in tolerance that demonstrates cross-tolerance with morphine. However, it appears that not all forms of AP are equally effective for providing analgesia. In particular, electro-AP seems to best deliver stimuli that activate powerful opioid and nonopioid analgesic mechanisms. Thus, future carefully controlled clinical trials using adequate electro-AP may be able to provide the necessary evidence for relevant analgesia in chronic pain conditions, such as headache, fibromyalgia, irritable bowel syndrome and low back pain.

Irritable bowel syndrome (IBS) is a functional disease with good prognosis, which is diagnosed by exclusion of possible causative organic diseases. However, since the patients tend to have strong psychotic symptoms including anxiety, tension, depression, irritation and insomnia, this syndrome has to be elucidated as a psychosomatic disease. Although the symptoms are usually limited to gastrointestinal symptoms such as abdominal pain and abnormal bowel movements, many patients also manifest some kinds of psychiatric abnormalities such as hypochondria, depression, hysteria, panic disorder and posttraumatic stress disorder. Especially, the prevalence of depression is high. Therefore, use of psychotropic drugs is efficient in treating IBS. Antidepressant agents including tricyclic agents such as amitriptyline, trimipramine, imipramine, clomipramine, amoxapine and nortriptyline; tetracyclic antidepressant; antidepressants such as SSRI and SNRI; sulpiride; benzodiazepine class anxiolytic agents; tandospirone; and Chinese herbal medicine are being used. IBS is a stress-related disease. Therefore, in spite of the importance of pharmacotherapy, patients should also be instructed to avoid the stress that aggravates the symptoms in all aspects of daily life.

Asian irritable bowel syndrome (IBS) studies not only confirm the truth of this functional disorder but also describe the current disease situation of this continent, with its variable socioeconomic backgrounds. Most Asian community IBS prevalence is within 5-10%, regardless of gender or ethnic character. As well as meeting the main Rome II criteria, Asian IBS subjects also have many minor symptoms. Thus this recommendation remains useful to diagnose Asian IBS. Also, female patients commonly express constipation-predominant (C-) symptoms. Extra-colonic symptoms are common in Asia, for example dyspepsia, insomnia and irritable urinary bladder. Asian IBS subjects do experience psychological disturbances including anxiety, depression, agoraphobia and neuroticism. Accordingly, their quality of life is poor and there is absenteeism leading to excessive physician visits. Abnormal gut motor and sensory functions have been indicated among the Asian IBS subjects. Now, there is evidence of altered colonic neuroimmune function leading to gut hypersensitivity and dysmotility. An Asia-Pacific trial also confirmed tegaserod efficacy on female C-IBS subjects. More than 90% of nurses have very limited IBS knowledge, and are unable even to explain it clearly. In conclusion, Western recommended criteria clearly diagnose Asian IBS and many factors are mutual leading to IBS. Current IBS treatments remain useful but additional reeducation for medical professionals appears to be needed.

Bupropion hydrochloride is currently available in three formulations: immediate-release, sustained-release, and extended-release (ER). Several published reports exist concerning bupropion's history of inducing seizures in both the immediate- and sustained-release formulations. Although the potential of the ER formulation for causing seizures is noted in the drug's prescribing information, there is no previously published report of bupropion ER inducing seizures. In the case reported, a 27-year-old woman who was prescribed bupropion ER as well as clonazepam and lamotrigine (anticonvulsants), hydrocodone bitartrate (for irritable bowel syndrome), and zolipidem tartrate (for depression and associated anxiety and insomnia) experienced a grand mal seizure 6 months after beginning bupropion ER therapy. The patient was taken to the emergency department, where she had a second grand mal seizure 8 hours after the first one. Extended-release bupropion was discontinued, and the patient had not had additional seizures at 8 months follow-up.

One of the most widespread aspects of psychosomatic pathology of gastrointestinal tract is irritable bowel syndrome (IBS). Over 70% of functional pathology of large intestine falls at IBS. The aim of the investigation was the assessment of depression rate in patients with IBS. Taking into consideration the age of individuals, 100 patients 50 men and 50 women aged 21 to 75 years were examined by using clinical, psychological and statistic (correlation) analysis to determine whether there were relations between clinical manifestations of the irritable bowel syndrome and personality. Diarrhea variant of IBS syndrome was detected in 17 (34%) men and in 21 (42%) females. Diarrhea and pain variant of IBS syndrome was detected in 12 (24%) men and 17 (34%) female. Pain variant of IBS syndrome was detected in 5 (10%) men and 12 (24%) females. Constipation variant was detected in 16 (32%) men and 3 (6%) female. In 84% of patients with IBS was found dysphoria; weight loss and bed appetite - in 44%, insomnia - in 40%, general lethargy and adynamia - in 80%; loss of interest - in 38%; asthenia - in 70%, devoured by guilt - 43%, uncertainty - 80%. Depression in patients with IBS was treated with serotonin selective antidepressants. Investigation revealed that the best result is achieved with serotonin-selective antidepressant therapy.

Mechanisms underlying chronic pain differ from those underlying acute pain. In chronic pain states, central nervous system (CNS) factors appear to play particularly prominent roles. In the absence of anatomical causes of persistent pain, medical sub-specialities have historically applied wide-ranging labels (e.g., fibromyalgia (FM), irritable bowel syndrome, interstitial cystitis and somatisation) for what now is emerging as a single common set of CNS processes. The hallmark of these 'centrally driven' pain conditions is a diffuse hyperalgesic state identifiable using experimental sensory testing, and corroborated by functional neuroimaging. The characteristic symptoms of these central pain conditions include multifocal pain, fatigue, insomnia, memory difficulties and a higher rate of co-morbid mood disorders. In contrast to acute and peripheral pain states that are responsive to non-steroidal anti-inflammatory drugs (NSAIDs) and opioids, central pain conditions respond best to CNS neuromodulating agents, such as serotonin-norepinephrine reuptake inhibitors (SNRIs) and anticonvulsants.
