Regular-dose versus high-dose omeprazole in peptic ulcer bleeding: a prospective randomized double-blind study.

BACKGROUND: It has been suggested that profound acid inhibition along with endoscopic therapy might prevent rebleeding and reduce mortality in patients with peptic ulcer bleeding. The aim of the study was to test the possible equivalence of a high dose and the regular dose of omeprazole in peptic ulcer bleeding. METHODS: We performed a prospective randomized double-blind study involving 142 patients with acute peptic ulcer bleeding (Forrest classification I-II: spurting or oozing bleeding, non-bleeding visible vessel, clot and black base). One-hundred-and-two (71.8%) patients received endoscopic treatment (adrenaline injection and/or heater probe) in pre-entry. Patients were randomly assigned to receive the regular dose of omeprazole intravenously (20 mg once a day for 3 days, i.e. 60 mg/72 h) or a high dose of omeprazole (80 mg bolus + 8 mg/h for 3 days, i.e. 652 mg/72 h). Rebleeding, surgery and death were the outcome measures. RESULTS: Six (8.2%) of the 73 patients receiving the regular dose of omeprazole and 8 (11.6%) of the 69 patients receiving the high dose of omeprazole rebled (P = 0.002 for equivalence, equivalence limit 0.15). Three (4.1%) of the former patients and 5 (7.2%) of the latter group underwent surgery. Four (5.5%) patients in the regular-dose and 2 (2.9%) in the high-dose group died within 30 days. CONCLUSION: Under the defined tolerance limits, the regular dose of omeprazole is as successful as a high dose in preventing peptic ulcer rebleeding.

All well at work? Evaluation of workplace-based early rehabilitation in the Finnish State administration.

A comprehensive system for the early rehabilitation of personnel has been developed and practised within the Finnish State administration since 1989. The rehabilitation process can be initiated as soon as the working capacity of a person or work community is threatened but is not yet seriously impaired. Rehabilitation is principally carried out on an outpatient basis alongside ordinary work. The aim of the study was to evaluate the outcomes and processes of early rehabilitation. The research data comprised several thousands of cases and consisted of a cross-sectional and a follow-up survey and a register-based follow-up. The surveys showed that during the rehabilitation period the average performance of the participants began to match that of the better-off non-participants, especially with respect to their general working capacity, mental well-being and occurrence of musculoskeletal problems. The sense of coherence rose in both groups, which can be partly attributed to positive changes in the workplace. In the group process, there also proved to be many factors contributing to achievement of the participants' rehabilitation objectives. The register-based follow-up showed that rehabilitation had a positive effect on average longer-term morbidity. In the cases of early retirement, the average retirement age of early rehabilitation participants was considerably higher than the average for the State sector as a whole. A system of outpatient early rehabilitation, where the rehabilitation programme and the development of working circumstances progress side by side, proved to give encouraging results at very moderate cost.

The effects of gender and age on the colonoscopic examination.

The data concerning the influence of gender and age on a patient's toleration of and the technical difficulty of colonoscopy are conflicting. One hundred eighty patients (108 women and 72 men) undergoing colonoscopy were categorized into three age groups: the young (aged 2040 years), the middle-aged (aged 41-60 years), and the old (aged 61-75 years). The endoscopists assessed the examination immediately after the procedure. The patients completed a questionnaire before leaving the endoscopy unit and again 2 weeks later. The women rated colonoscopy after the procedure more painful (p < 0.01) and in the repeat questionnaire more painful (p < 0.05) and more difficult (p < 0.05) than men. Also, the endoscopists judged colonoscopy to be more difficult (p < 0.001) and the time taken to reach cecum longer (p < 0.01) for women. The young experienced more discomfort than the middle-aged or the old, as evaluated after the procedure (p < 0.05). In the repeat questionnaire, the young reported more discomfort and pain than the middle-aged (p < 0.05). The endoscopists also judged the examination to be more difficult and the time taken to intubate cecum longer for the old than for the middle-aged (p < 0.05) or the young (p < 0.01). Correspondingly, the examination time was shorter among the young when compared with the middle-aged (p < 0.05) or the old (p < 0.001). The young were least willing to repeat the examination (p < 0.05). Colonoscopy is less tolerable and more difficult for women. Although colonoscopy among the old patients was technically more difficult, they tolerated the procedure better than the young.

Bone histomorphometry in celiac disease.

BACKGROUND AND AIMS: Bone metabolism in celiac patients is not well understood and there are no previous histomorphometric studies on bone of patients with celiac disease. The aim of the study was to investigate bone metabolism in celiac patients using bone histomorphometry, measurement of bone mineral density (BMD) and biochemical parameters. MATERIAL AND METHODS: The patient groups included 19 men and 23 women with previously diagnosed celiac disease in remission (group I), 7 women not in remission (group II) and 19 women and 9 men with newly diagnosed celiac disease (group III). Static and dynamic parameters of bone structure, formation and resorption were measured using undecalcified sections. The following parameters were obtained: bone volume (BV/TV; %), osteoid volume (OV/BV; %), osteoid surface (OS/BS; %), resoprtion surface (ES/BS; %), osteoid thickness(Oth; microm), mineral apposition rate (MAR; microm/day), and mineralization lag time (MinLag; day). BMD was measured at the spine (L2-4) and left femoral neck, trochanter and Ward's triangle. Serum calcium (S-Ca; mmol/L), alkaline phosphatase (AP; U/L), intact parathyroid hormone (S-PTH; ng/L), 25-hydroxyvitamin D (S-25(OH)D; nmol/L), cross-linked carboxyterminal telopeptide of human type I collagen (S-ICTP; microg/L) and C-terminal extension peptide of type I procollagen (S-PICP; microg/L) were analysed. RESULTS: In the histomorphometric analysis there were no significant differences in static or dynamic parameters between the groups. Very low bone mass (< 10%) was found in one patient in every group. OV/BV was increased (> 3.5%) in all groups (31% in group I, 13% in group II and 29% in group III). OS/BS was increased (> 36.5%) in groups I and III (17% and 29% respectively). In group II OS/BS was normal in all patients. Mineralization defect was found in four patients in group I and in two patients in group III with otherwise normal histomorphometric results. ES/BS was increased in three patients in group I and III and in one patient in group II. One female patient in group III had increased osteoid parameters, resorption surface, S-PTH and low concentration of vitamin D reflecting hyperparathyroid changes in bone. S-PTH was increased (66-87 ng/L) in four patients in group III and one of these patients had hyperparathyroid histological changes in bone. CONCLUSIONS: Static and dynamic histomorphometry of iliac crest bone biopsy are useful tools to evaluate bone metabolism in celiac disease especially if hyperparathyroidism or mineralization defect are suspected. Hyperparathyroidism may be a problem in the patients before introducing gluten-free diet. Mineralization defect and osteomalacic changes are common later on irrespective of whether the patients are in remission or not.

Conscious sedation and cardiorespiratory safety during colonoscopy.

BACKGROUND: Cardiorespiratory events during colonoscopy are common. The effect of sedative premedication on cardiorespiratory parameters during colonoscopy has not been studied in controlled, prospective trials. METHODS: One hundred eighty patients undergoing colonoscopy were divided into 3 groups: (1) sedation with intravenous midazolam (midazolam group); (2) sedation with intravenous saline (placebo group); and (3) no intravenous cannula (control group). Arterial oxygen saturation (SaO(2)), systolic and diastolic blood pressure and continuous electrocardiogram were recorded prior to, during and after the endoscopic procedure. RESULTS: Midazolam produced lower SaO(2) values during colonoscopy compared with placebo or control groups (p < 0.001, repeated measures analysis of variance). Systolic and diastolic blood pressure during colonoscopy were lower in the midazolam group than in the placebo group (p < 0.01 and p < 0.05, respectively), but no difference was found between the midazolam and the control groups. Hypotension (systolic blood pressure less than 100 mm Hg) occurred more frequently in the midazolam group (19%) than in the placebo (3%; p < 0.01) or control groups (7%; p < 0.05). ST-segment depression developed in 7% of patients during the recording with no difference between the groups. In 75% of cases ST-depression appeared prior to the endoscopic procedure. CONCLUSIONS: Premedication with midazolam induced a statistically significant decrease in arterial oxygen saturation and increased the risk for hypotension. However, colonoscopy proved to be a safe procedure both with and without sedation.

Effect of conscious sedation on cardiac autonomic regulation during colonoscopy.

BACKGROUND: Colonoscopy is associated with cardiovascular events including hypotension, hypertension, and myocardial ischemia. The pathogenetic mechanisms of these cardiovascular events are unknown, but there is evidence that the autonomic nervous system may play a role. Conscious sedation is often used to relieve the inconvenience caused by the procedure. In this study, we evaluated the effects of sedation on cardiac autonomic regulation during colonoscopy. METHODS: One hundred and eighty patients undergoing elective colonoscopy were prospectively randomized into three groups: (i) sedation with intravenous midazolam (midazolam group); (ii) sedation with intravenous saline (placebo group); and (iii) no intravenous cannula (control group). Continuous electrocardiogram was recorded prior to, during, and after the colonoscopic procedure. Heart rate variability (HRV) was assessed by means of the power spectral analysis; the powers of low-frequency (LF 0.04-0.15 Hz) and high-frequency (HF 0.15-0.40 Hz) components were calculated. RESULTS: Intubation of the colonoscope increased the LF component of HRV and decreased HF power in all study groups compared to baseline recording. Furthermore, compared to baseline, the LF/HF ratio--a marker of cardiac sympathetic regulation--increased during intubation in the midazolam (P < 0.001) and placebo (P < 0.05) groups, with no change in the control group. During intubation the midazolam group presented with higher LF and lower HF power than placebo (P < 0.001) and control groups (P < 0.01). Accordingly, the LF/HF ratio was higher in the midazolam group than in the placebo (P < 0.05) or control groups (P < 0.05). CONCLUSIONS: Midazolam potentiates the dominance of the sympathetic nervous system induced by colonoscopy. Therefore, conscious sedation with midazolam may contribute to the occurrence of cardiovascular events during colonoscopy.

Long-term management of gastro-oesophageal reflux disease with omeprazole or open antireflux surgery: results of a prospective, randomized clinical trial. The Nordic GORD Study Group.

BACKGROUND AND AIM: The efficacy of antireflux surgery (ARS) and omeprazole treatment in the control of gastrooesophageal reflux disease (GORD) are well established. We have compared these two therapeutic options in a randomized, clinical trial. PATIENTS AND METHODS: Three hundred and ten patients with erosive oesophagitis were enrolled into the trial. After a run-in period when all patients had < or = 40 mg of omeprazole daily to heal the oesophagitis and relieve symptoms, 155 patients were randomized to continuous omeprazole therapy and 155 to open antireflux surgery, of whom 144 later had an operation. One hundred and thirty-nine and 129 in the omeprazole and antireflux surgery groups, respectively, completed the 3-year follow-up. Symptoms, 24-h pH monitoring and endoscopy were used to document the outcome. Quality of life was evaluated by the psychological general well-being (PGWB) index and the gastrointestinal symptom rating scale (GSRS). RESULTS: Analysis of time to treatment failure (defined as moderate to severe GORD symptoms for > or = 3 days during the last 7 days, oesophagitis or changed therapy) revealed a significant difference in favour of antireflux surgery (P = 0.0016). Seventeen patients originally submitted to antireflux surgery experienced symptom relapse alone, 14 had oesophagitis at endoscopy and another six had omeprazole for different reasons, leaving 97 patients in clinical remission after 3 years. The corresponding figures in the omeprazole arm were 50 relapses, 18 with oesophagitis, two had surgery, leaving 77 patients in remission. Allowing a dose adjustment in the case of relapse in those on omeprazole therapy to either 40 or 60 mg, the curves describing the failure rates were not significantly different from each other. Quality of life assessment showed a comparable outcome in the two study groups. CONCLUSION: In this randomized multicentre trial we found antireflux surgery to be very efficacious in controlling GORD, a level of control which could also be achieved by omeprazole provided that advantage was taken of the opportunity of adjusting the dose.

Is routinely given conscious sedation of benefit during colonoscopy?

BACKGROUND: Sedative drugs are generally given to patients undergoing colonoscopy. However, the benefit of routinely administered conscious sedation for colonoscopy has not been studied in adequately controlled trials. METHODS: We randomly assigned 180 patients scheduled for diagnostic colonoscopy into 3 groups: (1) sedation with intravenous midazolam (midazolam group); (2) sedation with intravenous saline (placebo group); and (3) no intravenous cannula (control group). The endoscopist assessed the procedure immediately after the examination. The patients completed a questionnaire before leaving the endoscopy unit. Another questionnaire was sent to the patients 2 weeks after the examination. Answers were mainly given on a 100 mm visual analog scale. RESULTS: Shortly after the procedure, the patients in the midazolam group rated the examination less difficult than those in the placebo group (30 vs. 40 mm; p < 0.05; visual analog scale, 0 to 100 mm: 0 = not at all, 100 = extremely). However, no significant difference was found between midazolam and control groups (30 vs. 36 mm, respectively). Otherwise, there were no differences between the three groups with respect to the patients' or endoscopists' assessments or the examination time. CONCLUSIONS: Routinely administered sedation does not markedly increase patient tolerance or make colonoscopy technically easier.

Osteoporosis in adult patients with celiac disease.

We investigated the bone mineral density (BMD) and prevalence of osteopenia and osteoporosis in adult celiac patients with varying disease states. In this cross-sectional study the data on the severity of celiac disease and BMD were collected from 77 celiac patients (28 newly diagnosed and 49 previously diagnosed celiac patients), and BMD results were compared with those of 157 control subjects matched for age, gender, and menopausal status. The celiac patients had significantly lower BMD than the control subjects at the lumbar spine (-6%) and femoral neck (-5%). The mean BMD did not differ significantly among celiac patients classified by severity of disease. Based on Z scores, 35% of the celiac patients and 17% of the control subjects had low BMDs for age at the lumbar spine (p = 0.005), whereas 31% of celiac patients and 16% of control subjects had Z scores of < or =-1 at the femoral neck (p = 0.01). Altogether, 26% of all celiac patients, but only 5% of control subjects, were classified as having osteoporosis (T score < or =-2.5 SD) at the lumbar spine (p = 0.03), whereas osteoporosis was rare at the femoral neck in both groups (3% vs. 1%, p = 1.00). Prevalence of osteopenia and osteoporosis was highest in newly diagnosed celiac patients and in patients with disease not in remission. A low 25-(OH)D vitamin concentration was a typical biochemical abnormality in our patients (64% of men and 71% of women). The main associated variables of low BMD were age (men), low serum vitamin D level, low body weight, and postmenopausal status (women). The present study suggests that celiac disease constitutes a risk factor for osteoporosis. This finding applies particularly to untreated and poorly treated patients.

Bone recovery after a gluten-free diet: a 5-year follow-up study.

The purpose of our study was to investigate the recovery of bone disease in celiac patients during 5 years of a gluten-free diet. The study group consisted of 28 newly diagnosed celiac patients (9 men, 19 women) recruited between 1990 and 1991. Six patients withdrew from the 5-year follow-up. Compliance with the gluten-free diet was good: 96% at 1 year and 82% at 5 years. During the follow-up period, the body mass index increased significantly (8%). Both in men and women, bone mineral density (BMD) values determined by dual X-ray absorptiometry (DXA) increased at the lumbar spine (2%), the femoral neck (1%), the trochanter (6%), and the Wards' area (3%) during the follow-up. The increase in BMD was found already during the first year of follow-up. After 1 year, BMD increased or remained the same in 69% of the patients at the lumbar spine and in 67% of the patients at the femoral neck, 89% of patients at the throchanter, and 67% of patients at the Wards' area. During the 5-year follow-up, these figures were 52%, 46%, 68%, and 59%, respectively. At the baseline, 19 out of 28 patients, after 1 year, 14 out of 26 patients, and after 5 years, 2 out of 26 patients had low serum 25(OH)D vitamin values (p = 0.0001). A high serum parathormone value was noticed in 6 out of 25 patients at the baseline, but after 1 year, 5 of them showed normalized values (p = 0.03). According to our results, bone disease in celiac patients is cured in most patients during 5 years on a gluten-free diet. The improvement in BMD mostly occurred already within the first year after the establishment of a gluten-free diet.

Lack of effect of acid suppression therapy on gastric atrophy. Nordic Gerd Study Group.

BACKGROUND & AIMS: A hypothesis suggesting that profound acid inhibition therapy facilitates and hastens the development of gastric glandular atrophy in patients infected with Helicobacter pylori was investigated in this randomized study comparing omeprazole therapy with antireflux surgery (ARS) for chronic gastroesophageal reflux disease (GERD). METHODS: Patients with esophagitis and/or chronic GERD were enrolled; 155 patients were randomized to ARS and 155 to long-term omeprazole therapy. Baseline data were obtained and repeated after 3 years in 131 ARS patients and in 139 omeprazole-treated patients. Histopathologic status of the oxyntic mucosa was assessed according to the Sydney system. RESULTS: Forty omeprazole-treated patients were infected with H. pylori compared with 53 in the ARS group. Basal gastrin levels were significantly higher in H. pylori-infected patients, particularly in the omeprazole group. No further increases in serum gastrin levels were observed during 3 years. Despite 3 years of therapy, only slight changes were found in the prevalence of inflammation in the corpus mucosa of H. pylori-infected subjects. A slow progression of gastric glandular atrophy was observed in these patients irrespective of therapy with no obvious difference between treatment regimens. Intestinal metaplasia (all of type I) was only exceptionally observed with no difference between the treatment arms. CONCLUSIONS: Acid-suppressive therapy in the form of omeprazole maintained for 3 years facilitates neither the development of gastric glandular atrophy of the corpus mucosa nor the occurrence of intestinal metaplasia in H. pylori-infected GERD patients.

Comprehensive 1-year cost analysis of open antireflux surgery in Nordic countries. Nordic GORD Study Group. Gastro-oesophageal reflux disease.

BACKGROUND: Antireflux surgery is a highly effective treatment option in patients with severe gastro-oesophageal reflux disease. However, because of the increasing pressure of cost containment within health care, cost aspects must also be added to the decision-making process. METHODS: The aim of this analysis was to assess the total cost of open antireflux surgery during the first year after operation in 178 patients with chronic reflux, who were recruited into a controlled, prospective clinical trial. The study was carried out in 17 hospitals in the Nordic countries. RESULTS: The cost of the operation represented more than 90 per cent of the direct medical costs which amounted to approximately US $5700. For a patient in the work force the indirect cost, i.e. loss of production, represented 47 per cent of the total cost, which was about US $10800. CONCLUSION: The total cost profile of open antireflux surgery has now been established prospectively and can form a basis for future comparisons.

Outcome of open antireflux surgery as assessed in a Nordic multicentre prospective clinical trial. Nordic GORD-Study Group.

OBJECTIVE: To evaluate the outcome of antireflux surgery in various hospitals in Scandinavian countries. DESIGN: Partly randomised controlled study, and partly open study. SETTING: Hospitals throughout Norway, Sweden, Denmark and Finland. SUBJECTS: 310 patients with chronic reflux disease and oesophagitis who were initially entered into a randomised controlled study of omeprazole and antireflux surgery. INTERVENTIONS: Total fundic wrap, partial fundoplication, or omeprazole. MAIN OUTCOME MEASURES: Control of symptoms at one year. RESULTS: 154 patients who had their symptoms of reflux completely controlled with omeprazole were initially randomised to have an open operation but 10 refused, leaving 144 for analysis. 34 patients who had only a partial response were also offered operation; 120/178 (68%) had a total fundic wrap, and 53 (30%) partial fundoplication. 6 patients had postoperative complications that required reoperation and 123 made a completely uneventful recovery. Reflux was controlled in most patients, and only 10 (6%) required further treatment with omeprazole. The outcome in those patients who only responded partially to omeprazole was similar to that in patients who had a complete response. CONCLUSION: The outcome of antireflux surgery throughout Norway, Sweden, Denmark, and Finland is good.

Sonographic detection of intragastric blood clot.

An intragastric blood clot suggested by sonography and later confirmed at upper gastrointestinal series and at gastroscopy is reported. Sonographic findings were a moveable mass within stomach presenting as an arc-like hyperechoic surface with a strong posterior resonance artifact. Compression of the mass with a transducer induced the mass to move from antrum to corpus within stomach. We think that the demonstration of a blood clot within stomach can be suggested on the basis of typical sonographic findings as a secondary sign of a bleeded gastric or duodenal ulcer.

Usefulness of anti-Helicobacter pylori and anti-CagA antibodies in the selection of patients for gastroscopy.

OBJECTIVES: Screening of dyspeptic patients with serological tests for Helicobacter pylori before open-access gastroscopy has been suggested to be worthwhile. CagA-positive H. pylori strains may be associated with major pathology more often than CagA-negative strains. The usefulness of anti-H. pylori and anti-CagA antibodies in screening for gastroscopy was evaluated in unselected dyspeptic patients. METHODS: Four hundred consecutive, unselected dyspeptic patients (mean age, 56.8 yr) in primary care were investigated with gastroscopy, ultrasonography of the upper abdomen, laboratory tests (including serological tests for H. pylori and CagA), and other examinations if needed. The patients were followed for 1 yr. RESULTS: Results of serological tests were positive for H. pylori in 56.2% of patients, of whom 64.4% also had results positive for CagA. Use of H. pylori and CagA serology-based screening combined with a history of nonsteroidal anti-inflammatory drug use would have detected only 80 and 70% of the major pathologies (peptic ulcer, moderate or severe esophagitis, celiac disease, or malignancy), respectively, in these patients. Gastroscopy would have been avoided in 30 and 41%, respectively, if only patients who had positive results on serological tests or who were nonsteroidal anti-inflammatory drug users would have been referred. In patients younger than 45 yr of age (n = 87), 60-74% of gastroscopies would have been avoided, but 50-60% of major pathologies would have been missed, by using the screening strategy studied. One of the nine malignancies (all in patients >45 yr of age) was H. pylori-negative, and two were CagA-negative. CONCLUSIONS: Anti-CagA antibodies do not offer advantages compared with anti-H. pylori antibodies in screening patients for gastroscopy. A remarkable share of major pathologies are missed by both of these screening methods. Therefore, the results of these screening tests are not recommended as selective criteria for gastroscopy.

Development of a rapid PCR method for identification of Helicobacter pylori in dental plaque and gastric biopsy specimens.

A rapid and simple polymerase chain reaction (PCR) method was developed to detect Helicobacter pylori in gastric biopsy specimens and dental plaque samples. The primers were targeted to the 16S rRNA sequence of Helicobacter pylori strain ATCC 43504. The system was found to have a theoretical detection level of 0.5 to 5 Helicobacter pylori cells in a 5 microliters sample of dental plaque. In the absence of plaque, the detection level was even better: theoretically, 0.05 to 0.5 Helicobacter pylori cells were detected in water suspension. However, this appeared to be due to the presence of free bacterial DNA in the culture used for the sensitivity determination. Thus, the actual sensitivity of the system was found to be fewer than five Helicobacter pylori cells, irrespective of the type of sample used. The method was then used to analyse 29 dental plaque and gastric biopsy specimens collected from patients with a history of recurrent peptic ulcer disease. Fourteen stomach specimens were positive for Helicobacter pylori when tested with the PCR method, while the respective figures with culture, histological examination and the urease test were 11, 12 and 9. No positive dental plaque samples were observed.

Tumour-associated trypsin inhibitor (TATI) in patients with colorectal cancer: a comparison with CEA, CA 50 and CA 242.

A prospective study of 62 patients with colorectal cancer was carried out to evaluate the value of tumour-associated trypsin inhibitor (TATI) in the diagnosis and staging of this disease. The reference group consisted of 97 patients with benign gastrointestinal disease. Increased serum TATI levels were detected in 46 patients with colorectal cancer (sensitivity 74%), and the highest mean values were measured in the patients with stage II cancer. The frequency of elevated values was not affected by the stage of the disease, however. There were altogether 64 false positives (specificity 34%). In comparison to CEA and CA 242, TATI showed higher sensitivity at low (< 40%) specificity levels, but it was less sensitive at high (70-95%) specificity levels. The performance of the CA 50 test was poorest both at high and low specificity levels. The various combinations of TATI and other markers (two tests positive) did not offer any further advantage as compared to CEA alone. A marginally significant positive correlation (p = 0.07) was found between serum TATI and CEA values in colorectal cancer patients. The results suggest that TATI is a very sensitive marker in colorectal cancer, but its utility is limited because of its low specificity in symptomatic patients. Concomitant measurement of TATI and other markers does not seem to give any further benefit, and nor does TATI seem to have any significant value in staging of the disease. Our results also indicate that CEA is probably the best current test in colorectal cancer.
