Assessment of gastro-oesophageal reflux symptoms in Italian physicians -- a survey by Reflux Disease Questionnaire.

BACKGROUND: The prevalence of gastro-oesophageal reflux disease symptoms in physicians, as compared to that of the general population, is not known. METHODS: We submitted a validated Italian version of a simple questionnaire (Reflux Disease Questionnaire) to 490 physicians and 430 controls to assess: (i) the presence, frequency and severity of gastro-oesophageal reflux disease symptoms in the two populations; (ii) how the self-assessment of troublesome gastro-oesophageal reflux disease symptoms by physicians correlate with a pathological Reflux Disease Questionnaire, judged on the basis of a total Reflux Disease Questionnaire score >or=8. RESULTS: A valid and complete questionnaire was obtained in 456/490 (93.1%) physicians and 367/430 (85.3%) controls. Between the two groups there were no differences in terms of total Reflux Disease Questionnaire score or individual items, with the only exception of "severity of burning feeling behind breastbone" which was significantly higher in the physician group. An excellent correlation was found between the self-assessment by physician and the total Reflux Disease Questionnaire score. CONCLUSIONS: The prevalence of gastro-oesophageal reflux disease symptoms among Italian doctors is not different from that reported by a matched control group, and that their ability in self-assessing a troublesome gastro-oesophageal reflux disease is optimal.

Systematic review: maintenance treatment of gastro-oesophageal reflux disease with proton pump inhibitors taken 'on-demand'.

BACKGROUND: Proton pump inhibitors (PPI) therapy 'on-demand' is often used as an alternative to continuous maintenance therapy in gastro-oesophageal reflux disease (GERD). AIM: We conducted a systematic review with the specific objectives to ascertain whether on-demand PPI therapy was effective in preventing symptomatic relapse and to assess the relative efficacy of on-demand vs. continuous PPI maintenance strategy. METHODS: Randomized-controlled clinical trials comparing on-demand PPI vs. placebo or on-demand vs. continuous PPI therapy in GERD patients were identified by searching the Medline database and the Cochrane Controlled Trials Register. RESULTS: Seventeen studies were found which met inclusion criteria. Out of the 17 studies: five investigated exclusively patients with non-erosive reflux disease (NERD), four patients with NERD and mild oesophagitis, two patients with erosive oesophagitis only, and two patients with uninvestigated GERD symptoms, respectively. Four further studies were not investigating the effectiveness of the therapies but primarily pharmacoeconomic or quality of life parameters. CONCLUSIONS: On the basis of the analysis of 17 studies, we can conclude that on-demand therapy with currently available PPI appears to be effective in the long-term management of patients with NERD or mild and uninvestigated forms of GERD, but not in patients with (severe) erosive oesophagitis.

Natural history of gastro-oesophageal reflux disease without oesophagitis (NERD)--a reappraisal 10 years on.

BACKGROUND AND AIM: Ten years ago we published a study describing the 6-month outcome of 33 outpatients with typical gastro-oesophageal reflux disease symptoms and pH-metry proven excess gastro-oesophageal reflux but without endoscopical evidence of oesophagitis, currently referred to as patients with gastro-oesophageal reflux disease without oesophagitis. We now present an update of that report concerning morbidity, drug consumption and quality of life of the original patients 10 years after the initial diagnosis. METHODS: The study consisted of the retrieval and revision of all clinical and instrumental records concerning the cohort of 33 above-mentioned patients. Data are available regarding annual intervals within the first 5 years from original diagnosis and, subsequently, with a follow-up ranging from 7 to 14 years (median 10 years). The records of these 33 patients were reviewed, including the results of clinical visits at the outpatients department, of oesophagogastroduodenoscopies and pH- metries. Finally, a telephonic interview was conducted by means of a structured questionnaire, aiming at evaluating present symptoms, actual therapy if any, health-related quality of life and other information regarding any gastro-oesophageal reflux disease symptoms. RESULTS: Of the original 33 patients, 31 are still alive and 2 were lost to follow-up. Of the 29 remaining, only 1 is definitively not complaining of any gastro-oesophageal reflux disease-related symptoms. Within 5 years of the first diagnosis, oesophagitis was found in all but one of the 18 subjects who underwent repeated endoscopy. At the latest follow-up check, after a median of 10 years, out of the 28 still complaining of gastro-oesophageal reflux disease symptoms, 21 (75%) were presently taking antisecretory drugs (proton pump inhibitors and H-2 receptor antagonists) because of gastro-oesophageal reflux disease symptoms/lesions, 12 of whom intermittently or on demand and the remaining 9 continuously. Two patients (2/28) underwent antireflux surgery, but despite this were still taking antisecretory drugs (in one case H2-RA; in the other proton pump inhibitor). The health-related quality of life, self-evaluated by the patient by means of a VAS scoring from 0 (worst possible) to 10 (best possible) increased significantly from 3.2 to 6.5 from baseline (before therapy) to present time, possibly due to the positive effect of present therapy. CONCLUSIONS: Our study conducted on a cohort of endoscopy-negative patients with pH-metry-confirmed reflux disease has shown that after a median time of 10 years following the original diagnosis, the majority of patients have, in fact, developed reflux oesophagitis and are on prolonged antisecretory therapy because of recurrent gastro-oesophageal reflux disease symptoms/lesions. The study confirms that gastro-oesophageal reflux disease without oesophagitis, as well as gastro-oesophageal reflux disease at large, is a chronic disease characterised by increasing severity with time, which requires protracted medical therapy in a vast proportion of patients. Absence of endoscopic oesophagitis at presentation does not represent a positive prognostic factor.

Inflammatory bowel disease versus irritable bowel syndrome: a hospital-based, case-control study of disease impact on quality of life.

BACKGROUND: Inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS) are intestinal diseases perceived differently by patients and doctors: the former is considered essentially as an 'organic' disease (i.e. an illness in which the role of stress or psychological factors is at best secondary to the disease itself), whereas the latter is acknowledged as a 'functional' disorder (i.e. illness thought to be more in the 'mind' than in the body of the patient). Accordingly, the respective impact of the two diseases on patients' health-related quality of life (HRQOL) is perceived to be very different. We aimed to compare the relative impact of the disease on HRQOL, psychological profile and perceived burden of stressful life events in two groups of outpatients suffering from IBS and IBD and attending our outpatient department at an Italian university hospital. Eighty patients with IBD (26 with ulcerative colitis and 54 with Crohn disease) and 85 controls with IBS formed the patient samples of the study. METHODS: Three questionnaires were given to the patients while they were attending the outpatient department because of their previously diagnosed disease, namely the SF-36 (a generic well-validated tool for measuring HRQOL), the SCL-90 (for assessing the psychological profile of patients), and the Holmes & Rahe schedule (for the assessment of stressful life experiences). The results were then compared by means of analysis of variance (ANOVA) and Bonferroni-adjusted t test, when appropriate. RESULTS: HRQOL appeared to be similarly reduced in both disease groups (SF-36 overall mean value: 58.2 +/- 16.1 in IBS patients versus 56.4 +/- 22.3 in IBD patients: P > 0.05) in comparison with normative Italian data. Furthermore, the overall severity of psychological symptoms was not statistically different between patients suffering from IBD versus IBS, as shown by SCL-90 mean scores of 0.89 + 0.45 versus 0.83 +/- 0.48, respectively (P > 0.05). On the contrary, the severity of recent stressful life experiences was perceived to be higher by IBS than by IBD patients (mean SRE score: 110.8 = 110.2 versus 61.6 +/- 78.8; P < 0.05). CONCLUSION: Our study supports the notion that, at least in referral centres, patients with IBS show health-related quality of life, psychological distress and recent occurrence of stressful life events of severity at least comparable with age-matched IBD patients.

Altered bone metabolism in inflammatory bowel disease: there is a difference between Crohn's disease and ulcerative colitis.

OBJECTIVES: The aims of this study were to assess bone metabolism in inflammatory bowel disease (IBD) patients and to evaluate potential differences between Crohn's disease (CD) and ulcerative colitis (UC) with respect to the mechanisms underlying bone loss in this group of diseases. DESIGN AND SETTING: This was a cross-sectional study which started in 1992. Patients were randomly selected for invitation to participate and were examined during the years 1992-95 in one research clinic in Milan. SUBJECTS AND METHODS: Fifty-one patients suffering from CD (30 women and 21 men, mean age 38.7 +/- 13.2 years) and 40 with UC (15 women and 25 men, mean age 34.4. +/- 12.5 years) entered the study. Thirty healthy subjects were selected as sex- and age-matched controls (C). Spine and femoral neck bone mineral density (expressed as T score), calciotropic hormones (parathyroid hormone, PTH; 25-hydroxycholecalciferol, 25(OH)D3; 1,25-hydroxycholecalciferol, 1, 25(OH)D3) and biochemical markers of bone turnover (ostecalcin, OC; total alkaline phosphatase, ALP; type I collagen C-terminal telopeptide, ICTP) were evaluated. RESULTS: Spine and femur T scores were similar in the two groups (spine: CD = -1.49 +/- 1.46; UC = -1. 67 +/- 1.13; femur: CD = -1.80 +/- 1.36; UC = -1.60 +/- 1.03). Based upon the WHO guidelines, only 8% of CD patients and 15% of UC patients had a normal bone mineral density (BMD), 55% (CD) and 67% (UC) were osteopenic, and 37% (CD) and 18% (UC) were osteoporotic. The distribution amongst the three different diagnostic groups was not significantly different between CD and UC groups (P = 0.11). PTH and 25(OH)D3 concentrations were not significantly different between CD and UC patients and controls, whilst 1,25(OH)D3 concentrations were significantly lower in both CD and UC patients compared with controls (P < 0.05). Bone turnover was increased in UC but not in CD patients, as shown by significantly increased concentrations in UC patients of both OC (CD = 7.77 +/- 5.06, UC = 10.03 +/- 6.24, C = 6. 58 +/- 2.87, P < 0.05 vs. C) and ICTP (CD = 5.74 +/- 3.94, UC = 10.2 +/- 8.47, C = 3.48 +/- 0.95, P < 0.05 vs. CD and C). In a stepwise regression that included age, sex, disease duration and cumulative prednisolone dose as independent variables, the femur T score was significantly inversely related to disease duration (r2 = 0.125, F = 6.06) in CD patients. In UC patients, the spine T score was inversely related to age (r2 = 0.107, F = 5.49) and significantly related to sex (more negative in males: r2 = 0.3, F = 16.1); the femur T score was significantly related to sex (more negative in males) and inversely related to the cumulative prednisolone dose (r2 = 0.283, F = 7.3). CONCLUSIONS: These data show that IBD patients have a diffuse osteopenia, the degree of which is not different in CD and UC; however, bone turnover is significantly higher in UC. Finally, osteopenia is related to disease duration in CD, whilst it is related to the male sex and glucocorticoid treatment in UC.

Ultrasonographic features of long-standing primary intestinal lymphangiectasia.

This article describes a case of primary intestinal lymphangiectasia associated with protein-losing enteropathy and lower right leg lympoedema in a 20-year-old woman. Echographic findings showed dilation of the intestinal loops, regular and diffuse thickening of the walls, plical hypertrophy and impressive mesenteric oedema. Although diagnosis of the disease is substantially histological, the ultrasonographic characteristics of the lesions are fairly indicative and of certain diagnosis usefulness in patients with protein-losing enteropathy.

Prevalence of Helicobacter pylori infection and related upper gastrointestinal lesions in patients with inflammatory bowel diseases. A cross-sectional study with matching.

BACKGROUND: Although a reduced prevalence of Helicobacter pylori infection has been observed in inflammatory bowel disease (IBD) patients, the clinical significance of H. pylori infection in this setting remains unknown. The aim of this study was, therefore, to evaluate the prevalence of H. pylori infection in a large series of IBD patients and the frequency of gastroduodenal lesions in those who agreed to undergo upper GI endoscopy. METHODS: Two hundred and sixteen consecutive IBD patients (123 with Crohn's disease (CD) and 93 with ulcerative colitis (UC)) had their anti-H. pylori IgG titres measured. Two hundred and sixteen blood donors matched for age, sex, place of birth in Italy, and socioeconomic status served as controls. All patients were offered the possibility of undergoing endoscopy with antral and corpus biopsies regardless of their H. pylori status. RESULTS: The overall seroprevalence of H. pylori infection was 48% in IBD patients versus 59% in the control group (P < 0.05), with a significantly lower frequency in CD versus UC patients (41% versus 56%). After adjustment for age, education, and socioeconomic status CD remained associated with a significantly lower risk of H. pylori infection. Previous therapy with sulphasalazine but not with 5-aminosalicylic acid or with steroids/immunosuppressants was associated with a reduced risk of H. pylori infection both in CD and UC patients. One hundred and eighty-nine patients (110 with CD and 79 with UC) underwent endoscopy; the prevalence of peptic ulcer was similar in both groups (5.5% in CD and 5.1% in UC patients); however, 11 more CD patients had gastroduodenal ulcers that were interpreted as CD-related; 7 of these patients had never had foregut symptoms. Two CD patients had granulomatous gastritis at histology, and another 16 patients with CD had H. pylori-negative gastritis. CONCLUSIONS: IBD patients have a reduced prevalence of H. pylori infection as compared with matched healthy controls; this appears mostly attributable to a reduced frequency of H. pylori colonization in CD patients. Previous use of sulphasalazine is associated with a reduced risk of infection both in CD and UC patients. Of CD patients 10% have a gastroduodenal localization of their disease, which is often asymptomatic. Of CD patients 15% also have H. pylori-negative gastritis at histology.

Guidelines for the treatment of ulcerative colitis in remission.

The role is reviewed of sulphasalazine, 5-aminosalicylic acid (5-ASA), immunosuppressive agents and corticosteroids in the maintenance treatment of ulcerative colitis in remission. Sulphasalazine and oral 5-ASA are the drugs of first choice in preventing relapses for patients suffering from intermittent chronic ulcerative colitis. Rectally administered 5-ASA may be a valid alternative for treating patients with proctitis and left-sided ulcerative colitis. The optimal dosage of oral 5-ASA in the maintenance therapy of ulcerative colitis in remission is not clear. However, there is evidence that a higher dose of 5-ASA is more effective than low dosage in preventing relapses in patients in remission. For patients with chronically active or steroid-dependent ulcerative colitis who have achieved remission while taking immunosuppressants, continuing azathioprine or 6-mercaptopurine is indicated. Existing data cast doubts as to whether or not continuous maintenance is still necessary in patients suffering from intermittent chronic ulcerative colitis with prolonged endoscopic, clinical and histological remission.

Azathioprine in steroid-resistant and steroid-dependent ulcerative colitis.

We evaluated, retrospectively, the outcome of 56 patients (39 male, 17 female; mean age, 34 years; age range, 14-65 years) who received azathioprine for either steroid-resistant (group A, n = 10) or steroid-dependent (group B, n = 46) ulcerative colitis. The patients were followed for a mean of 29 +/- 17 months (median, 27 months). Twenty-four had left-sided colitis, 5 had subtotal colitis, and 27 had total colitis. The mean duration of the disease was 51 months (range, 2-192 months). At the beginning of azathioprine treatment (time 0), all patients had clinically severe disease and were taking 40 mg prednisolone per day. Azathioprine was used in addition to steroid therapy at a dosage of 2 mg/kg. The need for steroids, expressed as the median cumulative steroid dose (mg/year), and the number of clinical relapses (requiring steroid therapy) in the 2 years before azathioprine treatment, were compared with those of the 3-year follow-up with azathioprine treatment. A positive response to azathioprine was defined as (a) avoidance of colectomy, (b) a significant decrease in the median cumulative steroid dose, and (c) a significant decrease in the number of clinical relapses (expressed as number/patient/year). One patient in group A withdrew due to painful dyspepsia, and two patients in group B were lost to follow-up. Remission with complete elimination of steroids was achieved in 36 of 53 (64%), 23 of 35 (66%), and 18 of 26 (69%) patients in the first, second, and third years, respectively, of azathioprine treatment. Compared with the 2 years before azathioprine treatment, a significant decrease was observed of about 75% both in steroid consumption and in the number of clinical relapses during the 3 years of azathioprine therapy. Two of nine patients in group A and 2 of 44 patients in group B had colectomy after mean periods of 15 months and 24 months, respectively. Azathioprine is effective and safe in avoiding colectomy in patients with steroid-resistant and steroid-dependent ulcerative colitis; its use decreases both steroid requirements and clinical relapses.

Coated oral 5-aminosalicylic acid (Claversal) is equivalent to sulfasalazine for remission maintenance in ulcerative colitis. A double-blind study.

In a double-blind, single-center, 1-year prospective trial, we compared a pH-dependent Eudragit L-coated formulation of oral 5-aminosalicylic acid (5-ASA) (Claversal), 0.5 g b.i.d., and sulfasalazine (SASP), 1 g b.i.d., in the prophylactic treatment of quiescent ulcerative colitis. Forty-four patients received 5-ASA and 44 received SASP. Clinical, sigmoidoscopic, and histologic findings were assessed at 6 and 12 months. The two groups were comparable in all pretrial characteristics. No significant difference was observed in the relapse rate in the two groups either after 6 months [5-ASA 20.5%, SASP 27.5%, p = 0.32, 95% confidence interval (CI) 0.28 +/- 0.13] or after 12 months (5-ASA 38.4%, SASP 51%, p = 0.18, 95% CI 0.38 +/- 0.1). We conclude that (a) 5-ASA was as effective as SASP in maintaining remission of ulcerative colitis; (b) the relapse rate was, however, higher than expected in both groups; (c) the incidence of side effects was similar with both treatments.

Low Pentasa dosage versus hydrocortisone in the topical treatment of active ulcerative colitis: a randomized, double-blind study.

OBJECTIVES: To compare a low dosage (1 g/day) rectal preparation of 5-aminosalicylic acid in slightly acidic, buffered suspension (Pentasa) with a hydrocortisone 100 mg/day enema (Cortenema). METHODS: Fifty-two patients with mild to moderate distal ulcerative colitis were randomized under double-blind conditions to receive a rectal preparation of either Pentasa (1 g/day) or Cortenema (100 mg/day) for 3 wk. RESULTS: After 3 wk, both types of treatment resulted in statistically significant improvements in clinical and endoscopic activity. No significant difference was observed between the two drugs in any of the parameters considered, although a statistical trend in favor of Pentasa was evident when analysis was limited to clinical activity (p = 0.07). No side effects were reported in either group. CONCLUSIONS: Our experience confirms that short term topical treatment with a low dosage 5-aminosalicylic acid is at least as effective as 100-mg hydrocortisone enemas in treating mild to moderate distal ulcerative colitis and is generally well tolerated.

Meta-analysis of the effect of placebo on the outcome of medically treated reflux esophagitis.

BACKGROUND: To ascertain the placebo-induced effect in the treatment of reflux esophagitis, we reviewed all the English-language literature concerning the results of placebo-controlled trials of erosive/ulcerative esophagitis from 1976 to 1990. Twenty-two studies fulfilled our meta-analytic criteria. RESULTS: After 4 to 8 weeks of treatment, active drugs (cimetidine, ranitidine, nizatidine, omeprazole, metoclopramide, sucralfate) were significantly more effective than placebo in the healing of esophagitis, with a pooled rate difference (PRD) of 0.22 in favor of the active drug, an odds ratio (OR) of 2.57 (confidence interval (CI) = 2.0-3.3). Pooled mean healing rate (+/- SD) with the active drug was 47.3 +/- 24.0%, as compared with 26.8 +/- 18.0% obtained with placebo after 4 to 8 weeks of treatment. With regard to symptomatic response, complete disappearance of symptoms was observed in an average of 31.6% active-treated patients and in 11.8% of placebo-treated patients, respectively. The PRD was 0.20, and the OR 2.25 (CI = 1.65-3.06). The incidence of side effects was not statistically different for the two treatment groups. CONCLUSION: Placebo is a relatively inactive drug in the short-term treatment of erosive ulcerative reflux and does not appear to change the natural history of the disease.

Severe abdominal pain in patients with AIDS: frequency, clinical aspects, causes, and outcome.

BACKGROUND: The exact prevalence of abdominal pain in AIDS patients, as well as the entire spectrum of causative disorders, has not yet been well defined. In addition, the existing data derive almost exclusively from surgical series describing only those patients who have undergone emergency surgical procedures. METHODS: We reviewed our experience with patients presenting with severe abdominal pain from a large series of non-selected consecutive AIDS patients seen at our institution over a period of 4 years. RESULTS: Of 458 patients, 71 (15%) had severe abdominal pain, and its occurrence was associated with a reduced patient survival. Specific diagnoses were made premortem in 42 patients (59%), potential causes of pain were identified at postmortem examination in 23 patients (33%), whereas no specific causes were found in 6 patients (8%). Most of the causative disorders (65%) were AIDS-related, whereas HIV-independent pathologic conditions were found in only 18% of the patients. The predominant site of pain, combined with a few key symptoms, had a high predictive diagnostic value in nearly half of the patients. The indications for emergency laparotomy were limited and substantially similar to those of the non-HIV population. CONCLUSIONS: Severe abdominal pain frequently complicates the course of AIDS, and its occurrence is associated with reduced survival. In most patients it is due to disorders closely associated with the HIV infection. Specific causes of pain may be identified in most of the cases by an appropriate diagnostic evaluation.

Gonadotropin releasing hormone agonist treatment for severe menorrhagia in patients with contraindications to surgery.

Four patients with heavy menorrhagia, severe iron-deficiency anemia and contraindications to surgery were treated with a gonadotropin-releasing hormone agonist in a depot formulation. At 2 months of therapy they were all amenorrheic, and at 6 months the hematologic values had improved markedly. Gonadotropin-releasing hormone agonists may obviate emergency surgery in patients at high surgical risk or could constitute the first line of sequential therapeutic regimens, once general health conditions have improved.

Laparoscopy in the diagnosis of gynecologic chronic pelvic pain.

Laparoscopy was performed on 126 women with undiagnosed chronic pelvic pain. Abnormalities were demonstrated in 62.7% of the cases. Endometriosis was present in 32.5% of the women. Laparoscopy is useful in the differential diagnosis of chronic pelvic pain and is indicated when symptoms persist for over 6 months.
