The aim of this 16-week trial was to determine the safety and efficacy of a step-care regimen of ramipril, an angiotensin converting enzyme inhibitor, from the minimal active dose (2.5 mg) in patients treated for mild to moderate hypertension. The trial was conducted by 102 general practitioners in 770 patients with mild to moderate hypertension. After a response rate to a 4-week placebo therapy of 9.1%, 57.0% of patients given active treatment with ramipril responded to daily doses of 2.5 mg. Ramipril 5 mg daily was effective in 55.6% of the remaining patients. There was no apparent statistically significant difference between the treatments with ramipril 10 mg or a combination of ramipril 5 mg + Lasix 20 mg daily (44.7% and 47.4% response respectively) in a 6-week double-blind arm of the study. In total, more than 90% of patients responded to treatment with ramipril by the end of the study. The incidence of adverse events was generally low, such as headache, cough, dizziness, asthenia, cramps and nausea. The incidence of cough appeared to be related both to the dosage of ramipril given and to outbreaks of influenza syndrome. Thirty-eight patients discontinued active treatment as a result of minor events such as cough, dizziness or diarrhoea, and one case each of myalgia and papular rash. There were no significant variations in laboratory parameters during the study, especially fasting blood glucose and apolipoprotein A1 and B. The results of this study provide evidence of the safety and efficacy.(ABSTRACT TRUNCATED AT 250 WORDS)

Fusidic acid is an antibiotic with T-cell specific immunosuppressive effects similar to those of cyclosporin. Because of the need for the development of new treatments for Crohn's disease, a pilot study was undertaken to estimate the pharmacodynamics and tolerability of fusidic acid treatment in chronic active, therapy-resistant patients. Eight Crohn's disease patients were included. Fusidic acid was administered orally in a dose of 500 mg t.d.s. and the treatment was planned to last 8 weeks. The disease activity was primarily measured by a modified individual grading score. Five of 8 patients (63%) improved during fusidic acid treatment: 3 at two weeks and 2 after four weeks. There were no serious clinical side effects, but dose reduction was required in two patients because of nausea. Biochemically, an increase in alkaline phosphatases was noted in 5 of 8 cases (63%), and the greatest increases were seen in those who had elevated levels prior to treatment. All reversed to pre-treatment levels after cessation of treatment. The results of this pilot study suggest that fusidic acid may be of benefit in selected chronic active Crohn's disease patients in whom conventional treatment is ineffective. Because there seems to exist a scientific rationale for the use of fusidic acid at the cytokine level in inflammatory bowel disease, we suggest that the role of this treatment should be further investigated.

The newly recognized class of 5-hydroxytryptamine receptors (5HT3) may be involved in the induction of nausea, since their pharmacological antagonists are effective against emesis induced by chemotherapy. 5HT3 receptors are present on enteric neurons, and 5HT3 blockers may produce mild constipation; we thus hypothesized that 5HT3 receptors would modulate colonic motility. To determine if GR 38032F, a selective 5HT3 antagonist known to have antiemetic effects, influences colonic transit in health, a randomized, double-blind, placebo-controlled crossover study was performed. Using a radiopaque marker technique, colonic transit was quantified in 39 healthy volunteers (19 men, 20 nonpregnant women) 18-70 years of age. On a standard 25-g fiber diet, 16 mg of GR 38032F was given orally thrice daily. Gastrointestinal peptides (peptide YY, human pancreatic polypeptide, neurotensin, motilin, gastrin-cholecystokinin, substance P) were also measured in plasma fasting and postprandially. Mean total colonic transit time on placebo was 27.8 hr, while on GR 38032F it was 39.1 hr (P less than 0.0005). Transit times through the left colon (P less than 0.0005) and rectosigmoid (P less than 0.05) were prolonged by the drug, but right colonic transit was not significantly altered. Transit times did not correlate with age or gender, but subjects with shorter transit times were significantly more affected than were those with longer transit times. The peak release of peptide YY was minimally decreased following GR 38032F (P less than 0.01), but the peak and integrated postprandial responses of human pancreatic polypeptide, neurotensin, motilin, gastrin-cholecystokinin, and substance P were not significantly altered by the drug.(ABSTRACT TRUNCATED AT 250 WORDS)

Fusidic acid has previously been noted to prevent syncytial formation by human immunodeficiency virus (HIV) in vitro. Since this drug is a cheap, usually well-tolerated substance with known toxicity profile, an open, uncontrolled trial was undertaken to evaluate its possible efficacy in HIV disease. Twenty HIV antibody positive patients (10 with AIDS and 10 with ARC) were treated with sodium fusidate 500 mg every 8 h for up to 3 months. One patient died during therapy and six ceased treatment due to adverse events. Rash, nausea, diarrhea, and/or abdominal pain caused difficulties in all patients. There was no significant improvement in clinical state or T-helper cell levels, and no observed decrease in HIV p24 antigen during treatment. We conclude that in this open trial, sodium fusidate had no observable beneficial clinical, virological, or immunological effects.

16 patients with recurrent or metastatic carcinomas of the upper respiratory and digestive tract underwent a total of 55 courses of chemotherapy with Cisplatin and Bleomycin. The cytostatic treatment was performed under outpatient conditions. 0.75 mg./kg. Cisplatin was administered at intervals of 5-8 weeks. In addition, 15 mg. Bleomycin was administered weekly. Hydratation and diuresis were forced by 1000 ml. 0,9% NaCl solution and 1000 ml. levulose 5% with potassium substitution and 250 ml. mannitol 10% after an initial injection of 2 ml. Furosemid. The treatment was generally well tolerated. A nausea lasting 1-3 days was observed after Cisplatin application. Remission of tumours, stopping of tumour progression and a reduction of pain was achieved. The "performance status" was maintained. In 6 cases there was no effect.

We described a case of systemic lupus erythematosus (SLE) complicated with multiple intracerebral hemorrhage. A 52-year-old female with no history of hypertension had been treated with steroid hormone therapy for more than 15 years. Four days before admission, she experienced acute onset of headache and nausea. On the day of admission, the patient suffered from headache and nausea again followed by a deteriorated level of consciousness. The computed tomographic scan revealed two subcortical hematomas in the right frontal and left temporo-occipital area with atypical findings compared to those of the usual intracerebral hemorrhage. Cerebral angiography demonstrated that cortical arteries around the hematomas were markedly stretched and displaced. Multiple segmental stenosis and irregular lumen of the internal carotid artery and bilateral cortical arteries were possibly representative of vasculopathy. Transit time of blood flow was severely delayed with no apparent obstruction of the cerebral arteries, veins and dural sinuses. These findings suggested the existence of severely increased intracranial pressure. Emergent surgical evacuation of the hematomas was successfully performed with a favorable outcome for the patient. Intraoperatively, the brain was congested even after the evacuation of the hematomas. Surgical manipulation was able easily to cause bleeding from the cavity of the hematomas, which was hard to control. It is supposed that vasculopathy including fibrinoid degeneration and vasculitis may have affected the susceptibility of small arteries and veins to rupture in the present case. Subsequent increase of intracranial pressure might cause another hematomas by adding of hemodynamic stress to small vessels apart from those at the site of the first hemorrhage.

Swelling tablets administered in the fed state have been shown to provide therapeutic advantages in two marketed products, with the duration of delivery characterised with respect to food and tablet size. Metformin extended-release tablets are a diffusion-based swelling tablet demonstrating once-daily efficacy with good gastrointestinal solubility. Ciprofloxacin extended-release tablets are based on an erosional matrix that delivers the drug to the upper gastrointestinal tract over 6 h to provide once-daily efficacy with reduced incidences of nausea and diarrhoea. Furosemide extended-release tablets are another example of an erosional matrix designed to deliver furosemide to the duodenum and upper jejunum over 6 h to provide a more gradual diuresis and naturesis compared with the immediate-release product.

Cannabinoid (CB1) receptor activation acts neuronally, reducing GI motility, diarrhoea, pain, transient lower oesophageal sphincter relaxations (TLESRs) and emesis, and promoting eating. CB2 receptor activation acts mostly via immune cells to reduce inflammation. What are the key questions which now need answering to further understand endocannabinoid pathophysiology? GPR55. Does this receptor have a GI role? Satiety, Nausea, Vomiting, Gastro-Oesophageal Reflux, Gastric Emptying. Endocannabinoids acting at CB1 receptors can increase food intake and body weight, exert anti-emetic activity, reduce gastric acid secretion and TLESRs; CB2 receptors may have a small role in emesis. Question 1: CB1 receptor activation reduces emesis and gastric emptying but the latter is associated with nausea. How is the paradox explained? Q2: Do non-CB receptor actions of endocannabinoids (for example TRPV1) also modulate emesis? Q3: Is pathology necessary (gastritis, gastro-oesophageal reflux) to observe CB2 receptor function? Intestinal Transit and Secretion. Reduced by endocannabinoids at CB1 receptors, but not by CB2 receptor agonists. Q1: Do the effects of endocannabinoids rapidly diminish with repeat-dosing? Q2: Do CB2 receptors need to be pathologically upregulated before they are active? Inflammation. CB1, CB2 and TRPV1 receptors may mediate an ability of endocannabinoids to reduce GI inflammation or its consequences. Q1: Are CB2 receptors upregulated by inflammatory or other pathology? Pain. Colonic bacterial flora may upregulate CB2 receptor expression and thereby increase intestinal sensitivity to noxious stimuli. Q1: Are CB2 receptors the interface between colonic bacteria and enteric- or extrinsic nerve sensitivity? Relevance of endocannabinoids to humans. Perhaps apart from appetite, this is largely unknown.

Healthy donors (HDs) who were mobilized using lenograstim (LENO) and who were undergoing peripheral haematopoietic progenitor cell collection with apheresis (HPC-A) were enrolled in a surveillance protocol. In all, 184 HDs have been assessed with a median follow-up of 62 months (range 2-155). HDs received LENO at a median dose of 10 microg/kg (range 5-15). Bone pain was reported as the most frequent short-term adverse event (71.2%). Other commonly observed short-term symptoms included fatigue (19.0%), fever (5.4%), headache (27.7%), nausea (12.0%) and insomnia (22.3%). Spleen size increased in 4.3% of the donors. No vascular disorders or cardiac disease occurred. Long-term follow-up included monitoring of adverse events, neoplastic disease or other pathologies. Transit ischaemic attack occurred in one donor (39 months post-donation). One autoimmune event was reported at 28 months post-recombinant human granulocyte (rhG)-CSF (ankylosing spondylitis); one donor with a history of chronic obstructive pulmonary disease developed secondary polyglobulia (50 months post-rhG-CSF). One donor was diagnosed with lung cancer at 19 months post-donation. No haematological disease was observed. In conclusion, the short-term safety appears to be verified, whereas, although the study identified no increased risks of malignancy among HDs who received rhG-CSF, long-term safety requires more complete data sets, especially a longer follow-up and a larger number of HDs.

Thyroid disease is common, and its effects on the gastrointestinal system are protean, affecting most hollow organs. Hashimoto disease, the most common cause of hypothyroidism, may be associated with an esophageal motility disorder presenting as dysphagia or heartburn. Dyspepsia, nausea, or vomiting may be due to delayed gastric emptying. Abdominal discomfort, flatulence, and bloating occur in those with bacterial overgrowth and improve with antibiotics. Reduced acid production may be due to autoimmune gastritis or low gastrin levels. Constipation may result from diminished motility, leading to an ileus, megacolon, or rarely pseudoobstruction. Ascites in myxedema is characterized by a high protein concentration. Graves' disease accounts for 60% to 80% of thyrotoxicosis. Hyperthyroidism is accompanied by normal gastric emptying with low acid production, partly due to an autoimmune gastritis with hypergastrinemia. Transit time from mouth to cecum is accelerated, resulting in diarrhea. Steatorrhea is due to hyperphagia and stimulation of the adrenergic system. Diarrhea in medullary carcinoma of the thyroid (MCT) may be due to elevated calcitonin, prostaglandins, or 5-hydroxyindoleacetic acid. Ileal or colonic function may be abnormal. The esophagus may be compressed by benign processes, but more often by malignancies. MRI and CT scans are the best diagnostic modalities. The gastrointestinal manifestations of thyroid disease are generally due to reduced motility in hypothyroidism, increased motility in hyperthyroidism, autoimmune gastritis, or esophageal compression by a thyroid process. Symptoms usually resolve with treatment of the thyroid disease.
