The 24-h sleep-wake pattern of plasma LH was studied in 18 patients with severe weight loss. Sixteen patients had anorexia nervosa, one suffered from schizophrenia and one had a gastric ulcer. The age of the patients ranged from 13 to 31 years. Seventeen women and one boy participated in the study. Their weight ranged from 51 to 73% of the ideal body weight (IBW) at the first 24-h study which was at one week after admission to the hospital. Blood was taken through an indwelling venous catheter every 30 min. The patients' weight increased under behavioural therapy and they were re-studied when they had gained approximately 10% IBW and again prior to release from the psychiatric ward. The LH patterns were classified as infantile, pubertal or adult. All patients except for two had an infantile pattern at the first study. Except for the two patients who had no anorexia nervosa, all developed a pubertal and/or an adult pattern. All patients whose weight was below 69% IBW had an infantile LH pattern. All patients whose weight was below 69% IBW had an infantile LH pattern. Adult patterns were only seen when the body weight was greater than 80% IBW. The increase of the average 24-h LH values was slower the older the patients were and the longer they had been anorectic.

We had already made a report on outcome of schizophrenia (1986). The patients, 129 typical schizophrenia, were continuously observed over 30 years in the Kawagoe Dojinkai Hospital. Recently, we again evaluated their prognoses according to the same criteria as adopted in the first report, and divided them into the following five groups. [symbol: see text]: completely remitted group (21 persons, 16.3%), [symbol: see text]: almost remitted cases now holding jobs (23 persons, 17.8%), [symbol: see text]: Slightly remitted group showing good adjustment at home or hospital (41 persons, 31.8%), [symbol: see text]: maladjusted cases always showing an unfavorable condition (25 persons, 19.4%), x : incurable cases (19 persons, 14.7%). 1) In the last 8 years, there were 30 persons (23.3% of the whole patients) who showed prognostic changes (10 persons improved, 20 persons worsen). While the second group ([symbol: see text]) has seen fewer persons (12 persons down) than previous study, the third group ([symbol: see text]) has seen more persons (9 persons up). Each three groups, that is, the first two groups ([symbol: see text] + [symbol: see text], 44 persons, 34.1%), the third group ([symbol: see text], 41 persons, 31.8%), and the forth and fifth groups ([symbol: see text] + x, 44 persons, 34.1%) accounted for a third of the whole patients. It is after 32 years on the average (extending from 21 to 50 years) from the onset of illness that they showed prognostic changes. 2) Generally speaking, catatonic patients had favorable prognoses, hebephrenic patients unfavorable ones, and paranoid patients medium ones. But 4 improved persons in the forth and fifth groups were all hebephrenic type. 3) 17 among the 30 persons who showed prognostic changes were unstable type. They took a wave-like course. 4) 27 of all the 129 patients were dead. 25 were dead from disease mentioned below. Malignancy (8 persons), Cerebral vascular disease, Pneumonia and Diabetes (3 persons), Heart-failure (2 persons), Ileus, Myocardial infarction, Hepato-cirrhosis, Gastric ulcer, Tuberculosis and Natural death (1 person). 2 persons committed suicide. 5) Outcome of 45 patients who discontinued our medical therapy became clear as follows. [symbol: see text] + [symbol: see text]: 18 persons (40.0%), [symbol: see text]: 9 persons (20.0%), [symbol: see text] + x : 18 persons (40.0%). A smaller percentage of the patients belongs to the third group ([symbol: see text]) than that of our patients who were continuously followed by us.

Between January 1985 and September 1994, 21 patients with psychiatric disorders underwent various forms of surgery at our hospital. There were 12 men and 9 women with an average age of 57.6 years. The coexisting psychiatric disorders were schizophrenia in 15 patients, depression in 2, dementia in 2, mental retardation with epilepsy in 1, and Parkinson's disease in 1. All the patients had been receiving neuroleptic medications for a long period. The indications for surgery were: cholelithiasis in 6 patients, acute appendicitis in 4, perforation of the small intestine in 3, incarceration of an inguinal hernia in 2, and esophageal cancer, stomach cancer, bleeding from a gastric ulcer, perforation of a duodenal ulcer, strangulating ileus, and burns in 1 patient each, respectively. All of the patients who underwent elective surgery were given epidural anesthesia with or without general anesthesia. Antipsychotic medications were given until just prior to surgery and recommenced concurrent with the first meal. Abnormal behavior was observed in 11 patients (52.4%) postoperatively, but all the patients were discharged in accordance with recovery from their surgical disorder. Intra- and postoperative hypotension resistant to intravenous catecholamine administration was recognized in 9 patients (42.9%), and this peculiar complication should be borne in mind when patients with psychiatric disorders require surgical management.

Using clinical and pathologicoanatomic data, particular features of gastric ulcer accompanying schizophrenia have been studied. It was determined that the disease is characterized by the specific ulcer localization of the concomitant Helicobacter pylori-associated gastritis and motor disorders of upper gastro-intestinal tract in combination with psychiatric pathology unlike the somatic group. The propagation of the nosology under examination at schizophrenia is inverse to the severity index of psychosis development.

Using clinical and pathologoanatomic data, particular features of gastric ulcer at schizophrenia were studied. It was determined that in combination with psychiatric pathology the disease (unlike the somatic group) is characterized by specific localization of ulcer, Helicobacter pylori-associated gastritis and motor disorders of the upper gastrointestinal tract. The spreading of the nosology under study is inverse to the index of severity of the psychosis course.

The lifetime prevalence of duodenal ulcer in the United States is 8 to 10%, whereas another 1% of the population is affected by gastric ulcer. Both central and peripheral dopamine pathways may influence ulcer pathogenesis. Dopamine agonists prevent whereas antagonists augment stress- and chemically induced gastrointestinal ulcers in preclinical models. The dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,36-tetrahydropyridine (MPTP) depletes central dopamine and induces lesions in the substantia nigra, and, if given in high doses, MPTP induces a Parkinson disease-like syndrome and gastric ulcers. Because schizophrenia is attributed, in part, to an overactive dopaminergic system, persons with schizophrenia may display a reduced susceptibility toward gastrointestinal ulcers. A case-control study was conducted in patients represented in the 2002 National Inpatient Sample, the largest all-payer inpatient care database in the United States, consisting of 5 to 8 million inpatient hospital stays per year, which approximates a 20% sample of community hospitals. A significant association was observed between schizophrenia and diminished risk for duodenal (odds ratio [OR] 0.55; 95% confidence interval [CI] 0.45-0.67) and gastric (OR 0.54; 95% CI 0.46-0.63) (p < .01) ulcers but not for gastrojejunal ulcers (OR 0.44; 95% CI 0.16-1.20) (p = .11). Potential confounders such as age, gender, race, tobacco or alcohol dependence, and Helicobacter pylori infection were controlled in multivariate analyses. This observational study in a large sample of patients in community hospitals suggests that schizophrenia and attendant neurobiologic mechanisms (eg, variability in dopamine pathways) may act in concert to modify the composite risk for gastrointestinal ulcers. Dopamine pathways warrant further prospective research as new potential drug targets in ulcer disease.

Histamine plays an important role as neurotransmitter and chemical mediator in multiple physiological and pathophysiological processes in central and peripheral tissues. In the last century the extensive study of its actions in the human body, resulted in the identification of four G protein-coupled receptor (GPCR) subtypes (H1R-H4R), mediating numerous effects. The successful application of H1R and H2R antagonists/inverse agonists in the treatment of allergic conditions and gastric ulcer proved that these two receptors are excellent drug targets. Ligands for H3R are currently in advanced stages of clinical development for a broad spectrum of mainly central diseases (e.g. narcolepsy, Alzheimer's disease, epilepsy and schizophrenia). Meanwhile, preclinical research in the H4R field, focused on inflammatory and immunological processes, led to the evaluation of the first H4R-targeting clinical candidates. Drug development for each histamine receptor subtype will be discussed with a special focus on H3R and H4R ligands.
