In 74 patients (23 male, 51 female) with irritable bowel syndrome (IBS) and in 15 matched control persons, an assessment of depression by means of the Zung Depression Self-Rating Scale (ZDS) and a determination of the number of total lymphocytes and T lymphocytes were carried out. In patients with IBS, the depression score was significantly higher than in controls. Among patients with IBS, the intensity of depressive symptoms did not relate to age, gender or to the type of the illness. IBS patients with a depression score on ZDS of 50 or more (31% of subjects) had a significantly lower number of total lymphocytes and T lymphocytes than the rest of IBS patients. The results may suggest a possible association between depression and indices of cellular immunity in IBS patients.

Patients with chronic pelvic pain attending a tertiary referral centre show certain social, developmental and psychological characteristics. Specifically, they appear to have fewer children and to report more paternal overprotection, and a trend towards low maternal care compared to normals. They also show more depression, free-floating anxiety and somatic anxiety than such populations. The levels are similar to those found in other outpatient populations presenting with migraine or irritable bowel syndrome. Hostility levels are greater than those in normal subjects. Overall the present patient population reports the same degree of childhood sexual abuse as do many other female clinic and community sample populations. Sexual abuse is unlikely to be a specific aetiological factor in the development of chronic pelvic pain though it may yet be found to be important in subsets of the population.

A study was undertaken to assess the evaluation and treatment of chronic intractable rectal pain. Sixty consecutive patients, 23 males and 37 females with a mean age of 69 (range, 29-87) years and a mean length of symptoms of 4.5 years, were evaluated by questionnaire, office examination, anal manometry, electromyography, cinedefecography, and pudendal nerve study. In all cases, organic abdominopelvic and anorectal etiologies for the pain were excluded by extensive radiologic and endoscopic evaluation. All patients had failed conservative and medical therapy. Ninety-five percent of patients had one or more associated factors: constipation or dyschezia (57 percent), prior pelvic surgery (43 percent), prior anal surgery (32 percent), prior spinal surgery (8 percent), irritable bowel syndrome (10 percent), or psychiatric disorders (depression or anxiety; 25 percent). Possible etiologies for the pain included levator spasm or anismus in 62 percent, coccygodynia in 8 percent, and pudendal neuropathy in 24 percent of patients. Therapy for pain control included electrogalvanic stimulation (EGS) in 29, biofeedback (BF) in 14, and steroid caudal block (SCB) in 11 patients. Pain control was assessed by an independent observer at a mean of 15 (range, 2-36) months after completion of therapy. Continued successful pain relief was classified by patients as good or excellent after EGS in 38 percent, after BF in 43 percent, and after SCB in 18 percent; overall success was reported by 47 percent of patients. The presence of levator spasm, coccygodynia, or pudendal neuropathy did not influence outcome. The routine use of physiologic investigation of rectal pain may not be justifiable. Moreover, more than half of the patients were refractory to all three therapeutic options used in this study.

Variable blood pressure responses, manifesting either as a "white-coat" phenomenon or lability between office visits, confound hypertension management decisions. An attempt was made to determine whether these phenomena are associated with concurrent diagnoses of psychosocial dysfunction, therefore mitigating against antihypertensive medical therapy. Forty-seven patients with such variable blood pressure responses were identified in a rural family practice over a three-year period and compared to randomly selected age- and sex-matched controls for the following concurrent diagnoses: generalized anxiety, psychogenic spastic bladder, panic disorder, depression, alcohol use, chronic headache, fibromyalgia, temporomandibular joint syndrome, irritable bowel syndrome, and premenstrual syndrome. No statistical associations between white-coat hypertension and these diagnoses were demonstrated although a small sample size tempers conclusions. However, chi-square analysis (P < 0.01) of the phenomenon characterized by lability of blood pressure between different office visits demonstrated a statistical association with alcoholic hepatitis in men. White-coat hypertension is a diagnosis that may warrant disassociation from other psychosocial disorders, although further study is indicated. Physicians should remain attuned to the presence of lability of blood pressure in males and consider possible associations with alcoholism.

This multicenter, double-blind, placebo-controlled, parallel-group, randomized study assessed the efficacy, safety, and tolerability of a novel CCK-B antagonist CI-988 in the treatment of generalized anxiety disorder (GAD). Patients received placebo or CI-988 (300 mg/day, thrice daily) for 4 weeks. Patients with a primary diagnosis of GAD according to DSM-III-R criteria were randomized. The study design included a 1- to 2-week single-blind placebo baseline phase, followed by a 4-week double-blind treatment phase. Efficacy was measured weekly by Hamilton Rating Scale for Anxiety (HAM-A), Clinical Global Impressions of Severity and Change, UCLA-Multi Dimensional Anxiety Scale, and Hamilton Rating Scale for Depression. Patients were also evaluated to determine whether they met criteria for irritable bowel syndrome (IBS) at screening and were evaluated with a gastrointestinal visual analog scale at each visit. Eighty-eight patients were randomized to CI-988 (N = 45) and placebo (N = 43) at three centers. CI-988 did not demonstrate an anxiolytic effect superior to placebo in this clinical trial. There was no significant difference in mean change in HAM-A total between placebo (-7.73) and CI-988 (-8.64). However, a significant treatment-by-center interaction and a highly variable placebo response rate among the three centers limit the interpretation of the results. CI-988 did not have an effect on symptoms of IBS other than diarrhea, which worsened in patients with IBS. Other than a higher incidence of some gastrointestinal symptoms (diarrhea, dyspepsia, flatulence, and nausea), CI-988 was well tolerated. Results suggest that testing higher oral doses of CI-988 may be warranted.

Tachykinins belong to an evolutionarily conserved family of peptide neurotransmitters. The mammalian tachykinins include substance P, neurokinin A and neurokinin B, which exert their effects by binding to specific receptors. These tachykinin receptors are divided into three types, designated NK1, NK2 and NK3, respectively. Tachykinin receptors have been cloned and contain seven segments spanning the cell membrane, indicating their inclusion in the G-protein-linked receptor family. The continued development of selective agonists and antagonists for each receptor has helped elucidate roles for these mediators, ranging from effects in the central nervous system to the perpetuation of the inflammatory response in the periphery. Various selective ligands have shown both inter- and intraspecies differences in binding potencies, indicating distinct binding sites in the tachykinin receptor. The interaction of tachykinin with its receptor activates Gq, which in turn activates phospholipase C to break down phosphatidyl inositol bisphosphate into inositol trisphosphate (IP3) and diacylglycerol (DAG). IP3 acts on specific receptors in the sarcoplasmic reticulum to release intracellular stores of Ca2+, while DAG acts via protein kinase C to open L-type calcium channels in the plasma membrane. The rise in intracellular [Ca2+] induces the tissue response. With an array of actions as diverse as that seen with tachykinins, there is scope for numerous therapeutic possibilities. With the development of potent, selective non-peptide antagonists, there could be potential benefits in the treatment of a variety of clinical conditions, including chronic pain, Parkinson's disease, Alzheimer's disease, depression, rheumatoid arthritis, irritable bowel syndrome and asthma.

Functional disorders like functional dyspepsia, irritable bowel syndrome and non-cardiac chest pain are common diseases. No organic lesion can be found to explain the often disabling symptoms. Typical features of functional dyspepsia are anxiety, depression, neuroticism, visceral hypersensitivity, abnormal autonomic nerve activity with a weak vagal and an higher sympathetic tone, and impairment of gastric accommodation. This last abnormality may be due to weak vagal tone and poor adaptive relaxation of the proximal stomach. The degree of dysfunction of the variables is sometimes correlated, suggesting that the pathogenetic factors may be interacting in a viscious circle. Medical therapy is often unsuccessful, but extensive research in the field has given better insight into the pathophysiological mechanisms, giving hope for new therapeutic modalities, including visceral analgesics. It may still be difficult, however, to distinguish organic from functional disorders. Reliable tests of visceral hypersensitivity would be helpful in this respect.

Characteristics of personality and emotional condition were studied in 160 patients from Moscow (Russia) and Chardzhou (Turkmenistan) with various gastroenterological diseases: duodenal ulcer, chronic gastritis, chronic cholecystitis, irritable colon syndrome. Actual psychogenia occurred frequently in all the patients, children's psychogenia was more frequent in Moscow patients with duodenal ulcer. In patients with duodenal ulcer and chronic gastritis both from Moscow and Chardzhou the incidence of stress in everyday life was rather high. All the examinees suffered from mild or moderate depression found more frequently in Moscow patients with chronic gastritis.

Although researchers have studied irritable bowel syndrome (IBS), including its physiological and psychological characteristics and treatments' effectiveness, basic descriptive information about IBS has been limited to lists of symptoms and explanations of what IBS is not. The purpose of the present study is to describe how core IBS symptoms vary over time. Twenty-five subjects (17 females, 8 males), who were not receiving treatment for IBS, rated the severity of their IBS symptoms daily for 8 weeks. Four symptoms' (abdominal pain, abdominal tenderness, constipation and diarrhea) ratings were slimmed to create a primary IBS symptom score. The data were detrended, then a time-series analysis was performed. Many subjects' IBS severity was predictable over more than one day, and symptoms tended to occur in clusters rather than randomly. Anxiety and depression were slightly to moderately correlated with IBS variables, but virtually all of these correlations were nonsignificant.

Latent variable models of functional somatic symptoms were estimated for a sample of 686 family medicine patients. Symptom items from the NIMH Diagnostic Interview Schedule were selected to approximate diagnoses of fibromyalgia syndrome (FMS), chronic fatigue syndrome (CFS), and irritable bowel syndrome (IBS). Confirmatory factor analysis demonstrated that hypothesized latent variables of somatic depression, somatic anxiety, FM-like, CF-like, and IB-like syndromes fit the observed covariations better than models hypothesizing fewer latent variables. Results offer tentative confirmation of functional somatic syndromes as discrete entities and suggest that relaxing the diagnostic criteria for somatization may identify individuals with distress limited to a single functional system.
