Follow-up evaluation and management of anemia in inflammatory bowel disease: A study by the Italian Group for Inflammatory Bowel Diseases (IG-IBD).

BACKGROUND: The RIDART I study found a 13.6% prevalence of anemia in Italian patients with inflammatory bowel disease (IBD); most cases were due to iron-deficiency anemia (IDA). AIMS: To evaluate changes in hemoglobin concentration during a 24-week follow-up of anemic patients with IBD. METHODS: Follow-up laboratory and clinical data were obtained from RIDART I study patients with anemia. Factors affecting hemoglobin concentration, the impact of anemia on fatigue and quality of life (QoL), and its relationship with treatment, disease activity and disease complications were investigated. RESULTS: Hemoglobin was 108 g/L at baseline, increased to 121 g/L at follow-up week 12 (p < 0.001) and then stabilized until week 24, but most patients remained anemic, with IDA, throughout the study. Hemoglobin improvement was greater in patients receiving either oral or parenteral iron supplementation. Following hemoglobin normalization, anemia relapse rate during follow-up was 30%. Oral iron did not cause disease reactivation. Lower follow-up hemoglobin was associated with a higher probability of having active disease, clinical complications, increased fatigue and reduced QoL. CONCLUSIONS: In anemic patients with IBD, anemia represents a long-lasting problem, in most cases persisting for up to 24 weeks, with high relapse rate and a negative impact on fatigue and QoL.

Something new in the management of acute pancreatitis: brief review of recent guidelines and practical tips.

Improvement in diagnostic and therapeutic techniques has led to revision of past guidelines on the management of acute pancreatitis (AP), still not uniformly applied on the territory, partly due to the different distribution of resources to the various centers, partly due to the lack of unequivocal conduct in the approach itself. We had tried to outline most important changes emerged from the revision of recent and authoritative guidelines, focusing on what we believe are still critical points and identifying attitudes more equally shared than others. Based also on the experience of our small center, which however manages numerous cases of AP and their complications, we finally proposed a simple decision algorithm, which does not claim to be a codified recommendation, but only a small and concrete suggestion.

Prevalence, Pathogenesis and Management of Anemia in Inflammatory Bowel Disease: An IG-IBD Multicenter, Prospective, and Observational Study.

BACKGROUND: Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD), with a 6% to 74% prevalence and a negative impact on patient survival and quality of life, although the prevalence is apparently declining due to improved disease treatment. We aimed to investigate the prevalence, pathogenesis, and clinical correlates of anemia in Italian patients with IBD. METHODS: A multicenter, prospective, observational study, involving 28 Italian gastroenterology centers, was conducted to investigate the epidemiology and consequences of IBD-associated anemia. Clinical and laboratory data of anemic patients were obtained at study enrolment. RESULTS: Anemia was diagnosed in 737 of 5416 adult IBD outpatients (prevalence 13.6%); females were more commonly affected than males (odds ratio, 1.5; 95% confidence interval [CI], 1.2-1.7) and had more severe anemia. In the majority of cases, anemia was due to iron deficiency (62.5% of cases; 95% CI, 58.3%-66.6%), either isolated or in association with inflammation and/or vitamin deficiencies; anemia of inflammation accounted for only 8.3% of cases. More severe anemia was associated with increasing fatigue and worse quality of life. Only 68.9% of anemic patients with iron deficiency (95% CI, 63.4%-73.8%) and 34.6% of those with vitamin deficiencies (95% CI, 26.2%-44.2%) were properly treated with supplementation therapy. CONCLUSIONS: In Italy, the prevalence of IBD-associated anemia is lower than previously reported. Anemia of IBD is most commonly due to iron deficiency and contributes to fatigue and poor quality of life, but remains untreated in a large proportion of patients with iron and/or vitamin deficiencies. This study is registered at clinicaltrials.gov as NCT02872376.

The prevalence of inflammatory bowel disease­associated anemia is 13.6%. The prevalence is higher among females younger than 50. Anemia is usually due to iron deficiency and adversely affects fatigue and quality of life. Many patients with iron or vitamin deficiency (31% and 65%, respectively) remain untreated.

Management of Helicobacter pylori in Piedmont, Italy.

Helicobacter pylori (H. pylori) is a Gram-negative bacterium, usually acquired during childhood, whose natural habitat is the gastric lumen. H. pylori is accepted as the most important cause of gastritis and peptic ulcer in humans. Nevertheless, its important role in the pathogenesis of gastric cancer as well as in several extra-gastroduodenal diseases has been confirmed. The aim of this work is to discuss, for the first time in a single article, all publications concerning H. pylori infection arising from Piedmont region, Italy, where in 1893 Giulio Bizzozero was the first who observed and described spiral organisms in the stomach of animal models. A systematic review of all publications on the management of H. pylori in adults in Piedmont, based on a PubMed and a Scopus research from 1965 to 2017 was performed. The discussed aspects are the epidemiology, the study on gastric and extragastric diseases related to H. pylori, the diagnostic methods, the treatment of H. pylori infection, and the possibility of reinfection. In conclusions, with almost 70 publications, Piedmont has proudly maintained the tradition of the father of the H. pylori.

Type III intestinal metaplasia, Helicobacter pylori infection and gastric carcinoma risk index in an Italian series of 1750 patients.

BACKGROUND/AIMS: To evaluate the utility of 2 biopsies of antrum and gastric body on routine endoscopy for the assessment of type III intestinal metaplasia (IM-3) and Helicobacter pylori (Hp), 1750 patients (pts) (895 males; 855 females) were considered from June'98 to June'00. METHODOLOGY: Specimens were graded 0 to 3 for atrophy, IM-3 and Hp. 610 pts treated previously with antibiotics or not eligible for biopsy were excluded from initial 2360 pts. RESULTS: IM-3 was found in 118 pts (6.7%), 100 pts (5.7%) only in the antrum. 10 of 355 pts (2.8%) with normal endoscopy and 47 of 702 (6.6%) with non-erosive endoscopic gastritis resulted IM-3 positive in the antrum. 709 pts (40.5%) were positive for Hp in antrum and/or corpus. The presence of Hp and IM-3 in the antrum was not correlated (p=0.99; Spearman test). A positive correlation (p=0.000) between duodenal ulcer and Hp was found when antral Hp positivity was taken into account. The gastric carcinoma risk index (GCRI) was found in 358 pts (20.4%); in this group 131 pts (36.6%) were Hp positive, 81 pts (22.65%) had IM-3 only in the antrum, 184 pts (51.4%) had atrophy. CONCLUSIONS: The incidence of IM-3 is low (6.7%) in routine endoscopy. Normal endoscopy doesn't exclude the presence of IM-3. Biopsy is necessary to discover IM-3 in the antrum in 5.3% of pts with normal or aspecific endoscopic gastritis. Application of the GCRI might be useful for identifying a group of patients carrying a higher risk for gastric carcinoma.

Effect of Helicobacter pylori eradication on bulbitis and duodenal gastric metaplasia.

BACKGROUND/AIMS: Duodenal gastric metaplasia seems to be linked to infection by Helicobacter pylori, to the extent of acid secretion and to bulbitis. An investigation was made of the relationship between bulbitis and duodenal gastric metaplasia, or whether bulbitis can arise along with duodenal gastric metaplasia after Helicobacter pylori eradication in an average of six years. METHODOLOGY: We compared 22 patients with duodenal ulcers [male/female 16/6; (mean age+/-SD) 55+/-12 years] Helicobacter pylori-negative after eradication, with 23 Helicobacter pylori-positive patients free from active duodenal ulcers [male/female 17/6; (mean age+/-SD) 59+/-12 years]. RESULTS: The bulbitis score was found to be lower in the Helicobacter pylori-negative than in the Helicobacter pylori-positive group (p=0.02). The duodenal gastric metaplasia score in the Helicobacter pylori-negative was higher than in the Helicobacter pylori-positive group (p=0.001). We failed to find any relationship between the presence of bulbitis and duodenal gastric metaplasia. We found a non-significant inverse correlation between the presence of duodenal gastric metaplasia and chronic body gastritis (p=0.07). CONCLUSIONS: Bulbitis and duodenal gastric metaplasia may depend on different causal factors not related to Helicobacter pylori infection. The extension of duodenal gastric metaplasia with time following recovery from peptic ulcer disease may represent a mucosal protection factor against acid.

Durability of the response to peginterferon-α2b and ribavirin in patients with chronic hepatitis C: a cohort study in the routine clinical setting.

OBJECTIVES: To evaluate whether, in chronic hepatitis C-positive naive patients recruited in the routine clinical setting and treated with pegylated-interferon-α2b (Peg-IFN) and ribavirin (RBV), the sustained virologic response (SVR) is durable over the long term and whether it is associated with a decrease in liver complications and incidence of glucose abnormalities. PATIENTS AND METHODS: This was a prospective long-term follow-up study of 182 naive patients enrolled in 2001-2002 and treated with Peg-IFN and RBV and followed up to December 2010, with clinical, biochemical, and virological evaluations every 6-12 months. RESULTS: None of the 115 (63.2%) sustained responders showed late viremic relapse during the follow-up. SVR was better defined at 24 weeks (16/16 relapsers, 100%) than at 12 weeks after the end of therapy (14/16 relapsers, 87.5%). On multivariable analysis, viral genotype (odds ratio 0.16, 95% confidence interval 0.07-0.36, P=0.0001) and a greater than 20% RBV reduction (odds ratio 5.21, 95% confidence interval 1.54-17.67, P=0.008) predicted long-term response (LTR) independently. The incidence of cirrhosis was significantly higher among nonresponders (21.3%) compared with long-term responders (0.9%, P≤0.0001), but the risk of developing glucose abnormalities was not significantly reduced in long-term responders (hazard ratio 1.36, P=0.363). Hepatocellular carcinoma occurred only in three cases. CONCLUSION: SVR achieved in patients treated in the routine clinical setting with Peg-IFN and RBV is durable over the long term and LTR significantly reduces the risk of progression to cirrhosis; however, in a population with mild liver fibrosis, the clinical impact of LTR on the risk of glucose abnormalities seems negligible.

Appropriateness of colonoscopy in a digestive endoscopy unit: a prospective study using ASGE guidelines.

RATIONALE, AIMS AND OBJECTIVES: Appropriate indications for colonoscopy (C) are essential for a rational use of resources. The aim of this study is to evaluate the appropriateness of indication for C according to the American Society for Gastrointestinal Endoscopy (ASGE) guidelines and to evaluate whether appropriate use was correlated with the diagnostic yield of C. METHODS: We analysed 677 consecutive C performed over an 11-month period in a digestive endoscopy unit with an open access system. RESULTS: The rate of 'generally indicated' C was 77% and 'generally not indicated' C was 18%. The rate of indication not listed in the ASGE guidelines was 5%. The percentage of generally not indicated C requested by gastroenterologists for outpatients was lower than that requested by primary care surgeons or doctors (9.5%, 29%, 25.3%, respectively). In 38 (7.3%) and in 111 (21.3%) of 520 patients with appropriate C, cancer and polyps larger than 5 mm were found, respectively. Twenty polyps greater than 5 mm were detected in 15 cases (12%) of 122 inappropriate C, with only one case of intramucosal carcinoma; four (12%) polyps measuring over 5 mm were found in C not listed in ASGE guidelines. No advanced stage cancer was detected in the inappropriate group and in C not listed in ASGE guidelines. CONCLUSIONS: Our results showed the high rate of inappropriate procedures, according to ASGE guidelines, requested by surgeons, internists and primary care doctors for both outpatients and inpatients. The proportion of not indicated endoscopic procedures requested by gastroenterologists must be reduced through more carefully application of ASGE guidelines. Endoscopic findings were more stringent in appropriate C.
