As available data on Helicobacter pylori infection in patients with diabetes are scattered and discordant, we evaluated the prevalence of H. pylori and its relationship to dyspeptic symptoms in adult patients with diabetes and subjects with dyspepsia. H. pylori infection (evaluated using the 13C urea breath test) and dyspeptic symptoms (nausea, bloating, and epigastric distress) were investigated in 71 consecutive diabetic outpatients; the presence of gross lesions, histologic gastritis, and Helicobacter was verified in the patients with a positive urea test who agreed to undergo upper gastrointestinal tract endoscopy. Seventy-one age- and gender-matched subjects with dyspepsia were used as controls. Helicobacter pylori infection was detected in 49 (69%) patients with diabetes and in 33 (46%) subject with dyspepsia (p = 0.007). Helicobacter pylori was present in 27 (77%) of 35 patients with diabetes with dyspeptic symptoms and in 22 (61%) of 36 patients without dyspeptic symptoms. Endoscopy revealed peptic ulcers in 13 of 23 patients; H. pylori infection was histologically confirmed in the gastric antrum of all patients with diabetes, and in the body of the stomach in 74%. The significantly higher prevalence of H. pylori infection in the patients with diabetes may partially explain their dyspeptic symptoms. The high prevalence of H. pylori infection, esophagitis, and peptic ulcers found in our patients with diabetes (with or without dyspepsia) suggests that this population should be considered "at risk" for H. pylori infection and suitable candidates for treatment.

Eosinophilic gastroenteritis is a rare entity that can be treated successfully with glucocorticoid therapy if the appropriate diagnosis is made. However, it may present with symptomatology mimicking acute surgical conditions. We present the case of a 26-year-old man who presented with diffuse epigastric pain, nausea, vomiting, and diarrhea. Extensive workup including upper endoscopy and imaging study revealed gastritis with ulcer and ascites. The patient developed right lower quadrant pain with localized peritonitis and leukocytosis. He underwent appendectomy and small bowel biopsy. Pathology revealed eosinophilic cellular infiltrate of both the appendiceal and small intestinal wall. The unique features of this condition are reviewed and surgical approaches are discussed.

Dyspepsia with or without nausea is common during pregnancy. Known ulcer disease, gastritis, and GERD may improve during pregnancy. Many women have a stoic and long-suffering posture during pregnancy owing to an unrealistic expectation concerning the teratogenicity of commonly used drugs. It is appropriate in medicine to alleviate pain and suffering when possible, and many drugs can be used safely and effectively to control upper gastrointestinal tract symptoms. When symptoms are persistent into the late second trimester, refractory to pharmacologic treatment, or severe, H. pylori infection, complications of ulcer disease, and underlying cancer should be suspected and sequentially ruled out. More timely treatment and work-up of nonobstetric disease during pregnancy is expected to lower perinatal complications.

Lansoprazole is an inhibitor of gastric acid secretion and also exhibits antibacterial activity against Helicobacter pylori in vitro. Current therapy for peptic ulcer disease focuses on the eradication of H. pylori infection with maintenance therapy indicated in those patients who are not cured of H. pylori and those with ulcers resistant to healing. Lansoprazole 30 mg combined with amoxicillin 1g, clarithromycin 250 or 500mg, or metronidazole 400 mg twice daily was associated with eradication rates ranging from 71 to 94%, and ulcer healing rates were generally >80% in well designed studies. In addition, it was as effective as omeprazole- or rabeprazole-based regimens which included these antimicrobial agents. Maintenance therapy with lansoprazole 30 mg/day was significantly more effective than either placebo or ranitidine in preventing ulcer relapse. Importantly, preliminary data suggest that lansoprazole-based eradication therapy is effective in children and the elderly. In the short-term treatment of patients with gastro-oesophageal reflux disease (GORD), lansoprazole 15, 30 or 60 mg/day was significantly more effective than placebo, ranitidine 300 mg/day or cisapride 40 mg/day and similar in efficacy to pantoprazole 40 mg/day in terms of healing of oesophagitis. Lansoprazole 30 mg/day, omeprazole 20 mg/day and pantoprazole 40 mg/day all provided similar symptom relief in these patients. In patients with healed oesophagitis. 12-month maintenance therapy with lansoprazole 15 or 30 mg/day prevented recurrence and was similar to or more effective than omeprazole 10 or 20 mg/day. Available data in patients with NSAID-related disorders or acid-related dyspepsia suggest that lansoprazole is effective in these patients in terms of the prevention of NSAID-related gastrointestinal complications, ulcer healing and symptom relief. Meta-analytic data and postmarketing surveillance in >30,000 patients indicate that lansoprazole is well tolerated both as monotherapy and in combination with antimicrobial agents. After lansoprazole monotherapy commonly reported adverse events included dose-dependent diarrhoea, nausea/vomiting, headache and abdominal pain. After short-term treatment in patients with peptic ulcer, GORD, dyspepsia and gastritis the incidence of adverse events associated with lansoprazole was generally < or = 5%. Similar adverse events were seen in long-term trials, although the incidence was generally higher (< or = 10%). When lansoprazole was administered in combination with amoxicillin, clarithromycin or metronidazole adverse events included diarrhoea, headache and taste disturbance. In conclusion, lansoprazole-based triple therapy is an effective treatment option for the eradication of H. pylori infection in patients with peptic ulcer disease. Preliminary data suggest it may have an important role in the management of this infection in children and the elderly. In the short-term management of GORD, lansoprazole monotherapy offers a more effective alternative to histamine H2-receptor antagonists and initial data indicate that it is an effective short-term treatment option in children and adolescents. In adults lansoprazole maintenance therapy is also an established treatment option for the long-term management of this chronic disease. Lansoprazole has a role in the treatment and prevention of NSAID-related ulcers and the treatment of acid-related dyspepsia; however, further studies are needed to confirm its place in these indications. Lansoprazole has emerged as a useful and well tolerated treatment option in the management of acid-related disorders.

We aimed to determine if changes in the patterns of upper gastrointestinal diseases at endoscopy have occurred over the past decade. Retrospectively, 917 consecutive patients were selected based on upper endoscopy between June 1 and August 31, in 1990 (n = 217), 1994 (n = 270), and 1998 (n = 430). Demographic, clinical, endoscopic, and histological information were extracted from the medical records on a standardized case record form. Over the eight-year period, follow-up of peptic ulcer (15%, 5%, and 5%, respectively, in 1990, 1994, and 1998, df = 2, P < 0.001), bleeding (22%, 14%, and 13%, P = 0.008), and nausea/vomiting (15%, 16%, and 10%, df = 2, P = 0.003) had become less frequent, but reflux (21%, 19%, and 34%, df = 2, P < 0.001) and dyspepsia (24%, 43%, and 32%, df = 2, P < 0.001) more frequent indications for upper endoscopy. The prevalence of peptic ulcer disease decreased (22%, 15%, and 13%, df = 2, P = 0.025), but the prevalence of reflux esophagitis increased significantly (29%, 30%, and 39%, df = 2, P = 0.010). The prevalence of both the use of nonsteroidal antiinflammatory drugs (NSAIDs) (18%, 20%, and 11%, respectively, in 1990, 1994, and 1998, df = 2, P = 0.004) and H. pylori infection (39% in 1994 and 30% in 1998, df = 1, P = 0.032) decreased. Overall, NSAID use was independently associated with gastric ulcers (OR = 2.39, 95% CI 1.21-4.73, chi2 = 6.31, df = 1, P = 0.012), but not esophagitis. H. pylori infection was independently associated with duodenal ulcers (OR = 4.74, 95% CI 2.30-9.77, chi2 = 17.8, df = 1, P < 0.001), histologically chronic (OR = 166.8, 95% CI 76.1-365.4, chi2 = 313.0, df = 1, P < 0.001) and active (OR = 30.1, 95% CI 17.0-53.5, chi2 = 189.7, df = 1, P < 0.001) gastritis and lymphoid aggregates (OR = 5.49, 95% CI 3.02-9.97, chi2 = 36.3, df = 1, P < 0.001). In conclusion, the prevalence of peptic ulcer disease appears to have been decreasing, whereas reflux esophagitis has been increasing over the past decade in Western Sydney. The decreased use of NSAIDs and decline of H. pylori infection have likely both contributed to the reduction of peptic ulcer disease, but the increase in reflux esophagitis remains to be fully explained.

The present study was designed to determine the maximum tolerated dose (MTD), toxicity profile, pharmacokinetics (PKs), and antitumor activity of the protein kinase C-alpha antisense oligonucleotide ISIS 3521 (ISIS Pharmaceuticals, Inc., Carlsbad, CA) when administered in combination with 5-fluorouracil (5-FU) and leucovorin (LV). Patients with refractory solid tumors received ISIS 3521 as a 21-day continuous infusion administered simultaneously with 5-FU and LV given daily for 5 days repeated every 4-5 weeks (one cycle). 5-FU and ISIS 3521 PK analysis were performed on samples taken during the first cycle in all patients. Fifteen patients received ISIS 3521 at one of three dose levels: (a) 1.0 (n = 3 patients); (b) 1.5 (n = 3 patients); and (c) 2.0 (n = 9 patients) mg/kg/day. All patients simultaneously received 5-FU (425 mg/m(2)/day) and LV (20 mg/m(2)/day) for 5 consecutive days. Grade 1-2 toxicities included alopecia, fatigue, mucositis, diarrhea, anorexia, nausea/vomiting, and tumor pain. One patient had grade 3 chest pain considered to be related to 5-FU therapy, another patient had dose-limiting grade 3 mucositis resolving in <7 days, and one patient with a history of gastritis had an acute upper gastrointestinal bleed thought to be 5-FU-induced toxicity. Five patients developed cycle 1 grade 4 neutropenia, which resolved without colony-stimulating factors before the next treatment cycle. There were no effects on prothrombin time and activated partial thromboplastin time. A clinically defined MTD was not reached. The character and severity of these toxicities do not seem to be dose related, and, as such, there was no classical dose-limiting toxicity defining the MTD. ISIS 3521 PKs in the presence of 5-FU was consistent with those reported previously. 5-FU PK parameters were also similar in the presence or absence of ISIS 3521. Six of 14 patients ( approximately 43%) across all dose cohorts had an improvement in measurable tumor response ranging from minor reduction in tumor size (4 patients) to objective partial response (>50% reduction in tumor size, 2 patients). ISIS 3521 is tolerable at its recommended single-agent dose when given with 5-FU and LV. There is no apparent PK interaction between ISIS 3521 and 5-FU and LV. Antitumor activity was observed with the combination; however, it is uncertain whether clinical activity is a result of enhanced drug interaction. Our study warrants further exploration of efficacy in a Phase II and/or Phase III clinical trial setting.

Duplication of the pylorus, an extremely rare congenital anomaly of the stomach, consists of two openings connecting the antrum of the stomach to the duodenal bulb. Approximately 70 cases of double pylorus have been described in the literature, most of which are associated with the presence of chronic peptic ulcers, thus indicating an acquired origin of the condition. We report a case of congenital double pylorus in a 64-year-old man who complained about mild postprandial epigastric discomfort and nausea of approximately 3 months' duration. Endoscopic examination of the stomach showed a double pyloric ostium connecting the stomach to the duodenum. No signs of acute or chronic peptic ulcer were noted. A biopsy was taken from the region between the two openings, which showed normal mucosa and a muscularis mucosae layer. Apart from a mild gastritis, no other pathology (chronic peptic ulcer, ulcerated malignancy) suggesting an acquired origin of the double pylorus was observed. Therefore, the case was considered to be congenital in origin. The patient was successfully treated conservatively with antacids and gastrokinetics.

A 69-year-old-woman presented with acute epigastric pain, nausea, vomiting and heartburn. Endoscopy disclosed acute gastric mucosal lesions including mucosal edema, erosions, and ulcers with blood crusts in the antrum. Touch cytology and histological assessment obtained from the affected mucosa revealed acute neutrophilic gastritis and single longer and more coiled organisms than Helicobacter pylori, suggesting Helicobacter heilmannii. Electron micropragh confirmed the characteristic morphology. Despite a positive rapid urease test, H. pylori was not isolated by culture or detected by histology and Gram smears. Based on these findings, a diagnosis of acute gastric mucosal lesions associated with H. heilmannii infection was established. This was successfully treated with a 2-week triple therapy consisting of lansoprazole, clarithromycin and metronidazole with persistent endoscopic and histological remission. This is a rare case of H. heilmannii-associated acute gastric mucosal lesions, diagnosed by morphology using touch cytology and histology. The patient might benefit from antimicrobial treatment employing the regimen effective for H. pylori.

The aim of our study was to evaluate and compare the therapeutic efficacy & safety profile of three different antituberculous regimens for pulmonary tuberculosis. The study sample size included 90 newly diagnosed, sputum positive patients of pulmonary. tuberculosis. 30 each from different groups. The parameters studied were, therapeutic efficacy included weight gain, cough, sputum examination and safety profile: nausea, vomiting, anorexia, gastritis, hepatitis, jaundice diarrhoea, rashes, dizziness, tingling & numbness, flu like symptoms & joint aches. Group-I showed statistically significant weight gain when compared to Group-II. Improvement in cough and conversion to smear negative were seen in 100% of patients in Group-I, 83.3% of patients in Group-II and 93.3% of patients in Group-III. Therapeutic efficacy was highest with Group I regimen, followed by Group III and Group II which was least efficacious. Group II also registered; the maximum cost and highest incidence of adverse effects.

Alendronate sodium is an aminobiphosphonate, an analog of inorganic pyrophosphate, indicated for the treatment of osteoporosis in post-menopausal women. We analyzed events reported in patients prescribed alendronate by general practitioners (GPs) in England. A non-interventional observational cohort study was conducted using the technique of prescription event monitoring (PEM). Exposure data were obtained from dispensed prescriptions issued between October 1995 and January 1997. Outcome data were obtained by sending questionnaires to prescribing GPs. The cohort comprised 11,916 patients. Events most frequently reported as suspected adverse drug reactions and reason for stopping alendronate were recognized gastrointestinal events listed in the Summary of Product Characteristics. These included nausea/vomiting, abdominal pain, dyspepsia, esophagitis and esophageal reflux. Events with the highest incidence density (ID(1) per 1000 patient months treatment) were dyspeptic conditions (32.2), nausea/vomiting (20.8) and abdominal pain (13.8). The term dyspeptic conditions included dyspepsia, esophagitis, esophageal reflux, duodenitis, gastritis and heartburn. Serious suspected adverse reactions possibly related to alendronate were single reports of angioedema, erythema multiforme, hypercalcemia and hypocalcemia. There were 540 deaths in this elderly cohort. This study suggests that alendronate appears to be well tolerated, though there may be risk of developing gastrointestinal side effects including esophagitis and esophageal ulcers.
