Bismuth quadruple regimen with tetracycline or doxycycline versus three-in-one single capsule as third-line rescue therapy for Helicobacter pylori infection: Spanish data of the European Helicobacter pylori Registry (Hp-EuReg).

BACKGROUND: Different bismuth quadruple therapies containing proton-pump inhibitors, bismuth salts, metronidazole, and a tetracycline have been recommended as third-line Helicobacter pylori eradication treatment after failure with clarithromycin and levofloxacin. AIM: To evaluate the efficacy and safety of third-line treatments with bismuth, metronidazole, and either tetracycline or doxycycline. METHODS: Sub-study with Spanish data of the "European Registry on H pylori Management" (Hp-EuReg), international multicenter prospective non-interventional Registry of the routine clinical practice of gastroenterologists. After previous failure with clarithromycin- and levofloxacin-containing therapies, patients receiving a third-line regimen with 10/14-day bismuth salts, metronidazole, and either tetracycline (BQT-Tet) or doxycycline (BQT-Dox), or single capsule (BQT-three-in-one) were included. Data were registered at AEG-REDCap database. Univariate and multivariate analyses were performed. RESULTS: Four-hundred and fifty-four patients have been treated so far: 85 with BQT-Tet, 94 with BQT-Dox, and 275 with BQT-three-in-one. Average age was 53 years, 68% were women. Overall modified intention-to-treat and per-protocol eradication rates were 81% (BQT-Dox: 65%, BQT-Tet: 76%, BQT-three-in-one: 88%) and 82% (BQT-Dox: 66%, BQT-Tet: 77%, BQT-three-in-one: 88%), respectively. By logistic regression, higher eradication rates were associated with compliance (OR = 2.96; 95% CI = 1.01-8.84) and no prior metronidazole use (OR = 1.96; 95% CI = 1.15-3.33); BQT-three-in-one was superior to BQT-Dox (OR = 4.46; 95% CI = 2.51-8.27), and BQT-Tet was marginally superior to BQT-Dox (OR = 1.67; 95% CI = 0.85-3.29). CONCLUSION: Third-line H pylori eradication with bismuth quadruple treatment (after failure with clarithromycin and levofloxacin) offers acceptable efficacy and safety. Highest efficacy was found in compliant patients and those taking 10-day BQT-three-in-one or 14-day BQT-Tet. Doxycycline seems to be less effective and therefore should not be recommended.

Prospective, study comparing the accuracy of two different stool antigen tests (Premier Platinum HpSA and novel ImmunoCard STAT! rapid test) for the diagnosis of Helicobacter pylori infection.

BACKGROUND: At present only monoclonal EIA (enzyme-immunoassay) stool antigen-tests have obtained optimal accuracy in the diagnosis of Helicobacter pylori. Our aim was to evaluate the accuracy of two stool antigen-tests, the validated Premier Platinum HpSA PLUS (EIA test) and the newly available ImmunoCard STAT! HpSA HD (rapid test) for the initial diagnosis and the confirmation of eradication of H. pylori infection. PATIENTS AND METHODS: Patients with indication of H. pylori diagnosis, or confirmation after treatment were included. Data were coded to protect personal data and ensure blindness between tests. Accuracy was considered as coincident diagnosis with the gold standard (13C-urea breath test, UBT). The EIA was used as a bench standard. All stool tests were performed in duplicate. RESULTS: 264 patients completed the protocol (100 naïve, 164 post-eradication). Average age was 52 years, 61% women, 11% ulcer. Positive diagnoses by UBT were 41% for naïve and 17% for post-eradication. Overall ImmunoCard and EIA accuracies were respectively 91% (95%C.I.=88-94%) and 89% (86-93%), sensitivities 72% (67-78%) and 72% (67-78%), and specificities 98% (96-100%), and 95% (92-97%). Concordance between ImmunoCard and EIA was 95% (93-98%). DISCUSSION: Our results indicate that the newly available ImmunoCard rapid stool antigen-test achieves 90% accuracy, with high specificity but suboptimal sensitivity. The ImmunoCard attained equivalent accuracies as the EIA bench standard, with 95% concordance.

[Use of intravenous iron infusion in a gastroenterology day hospital: Indications, dosage and adverse effects]. / Uso del hierro intravenoso en un hospital de día de aparato digestivo: indicaciones, dosificación y efectos adversos.

UNLABELLED: There are no data in the literature on the use of intravenous iron infusion in gastroenterology day hospitals. OBJECTIVE: To determine the indications, dosage and tolerance of intravenous iron infusion in outpatients attending a gastroenterology day hospital. MATERIAL AND METHODS: We retrospectively reviewed the medical records of patients who received intravenous iron infusion between August 2007 and July 2008. The indications, dosage, transfusion requirements, adverse effects and patients' clinical and laboratory data were recorded. RESULTS: During the study period, 111 patients (41% women, with a mean age of 63.8 ± 18 years) received intravenous iron infusions. The main causes of anemia indicating iron administration were portal hypertensive gastropathy (n=55), inflammatory bowel disease (n=22) and intestinal angiodysplasia (n=12). The patients received a total of 557 iron infusions with a mean dose of 1033 mg iron per patient. There were no adverse effects. Despite the treatment, 46 patients required transfusion. Iron and transfusion requirements and mortality were significantly higher in patients with liver cirrhosis than in the remainder of the study group. CONCLUSION: Intravenous iron therapy is frequently used in the gastroenterology day hospital. Most infusions were administered in patients with chronic iron loss. Patients with liver cirrhosis had the most severe anemia and underlying disease and the highest mortality.

A Prospective Pilot Randomized Study: Electroacupuncture vs. Sham Procedure for the Treatment of Fatigue in Patients With Quiescent Inflammatory Bowel Disease.

BACKGROUND: Fatigue is a common symptom in patients with inflammatory bowel disease (IBD), and it often persists despite clinical remission. Acupuncture has been shown to be effective for treating fatigue in patients with many chronic diseases. The main objective of the study was to assess the efficacy of electroacupuncture (EAc), compared with sham EAc (ShEAc) or being on a waitlist (WL), for treating fatigue in patients with quiescent IBD in a single-blind randomized trial. METHODS: Fifty-two patients with IBD in clinical remission and fatigue were randomly assigned to 1 of 3 groups: EAc, ShEAc, or WL. Patients in the EAc and ShEAc groups received 9 sessions over 8 weeks. Fatigue was evaluated with the IBD-validated Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-FS). RESULTS: Baseline characteristics were similar in the 3 groups. Both EAc and ShEAc presented improved Functional Assessment of Chronic Illness Therapy-Fatigue Scale scores compared with baseline: the respective improvements were 9.53 (95% confidence intervals, 6.75-12.3, P < 0.001) and 5.46 points (95% confidence intervals, 2.7-9.7, P = 0.015), respectively. No significant changes were observed in the WL group. In the comparison of treatment groups, EAc was nonsignificantly better than ShEAc (EAc, 33.27 and ShEAc, 28.13, P = 0.168); both EAc and ShEAc improved fatigue scores significantly compared to WL (24.5; P = 0.01 and 0.04, respectively). CONCLUSIONS: Both EAc and ShEAc reduced fatigue scores in IBD patients when compared to WL. No differences were observed between EAc and ShEAc, although the study was not powered to rule out a difference. Acupuncture may offer improvements to patients with few other treatment alternatives.

Fatigue in out-patients with inflammatory bowel disease: Prevalence and predictive factors.

BACKGROUND AND AIM: Fatigue is a common and bothersome symptom in inflammatory bowel disease (IBD) patients. The study was aimed to determine the relationship of biological and psychological factors with IBD-related fatigue. METHODS: Consecutive clinically inactive IBD outpatients receiving immunosuppressants or biological drugs were enrolled between January and December 2013. Patients completed a Fatigue score (FACIT-F), various psychological, quality of life (IBDQ-9), and IBD activity scores. Biological parameters were assessed, including levels of interleukins (IL-5, IL-8 and IL-12) and micronutrients. RESULTS: We prospectively recruited 202 patients (28% ulcerative colitis and 72% Crohn's disease) for the study. Fatigue measured by FACIT-F score was prevalent in the studied population (54%, 96/177) and higher than in the general population. In the univariate analysis no relation was found between IL levels or micronutrient deficiencies and fatigue. Fatigue was significantly related to female sex, Crohn's disease, joint disorders, body mass index (BMI), psychological tests, thiopurine use, and anti-TNF treatment. All these variables were included in the multivariate analysis. Female sex (OR: 4.8), high BMI (OR:1.2) and higher depression rates (OR:1.2) were predictors of increased fatigue. High IBDQ-9 score (OR: 0.82) was significantly related to lower degrees of fatigue. CONCLUSION: Fatigue was prevalent in quiescent IBD patients with moderate-to-severe disease. It was associated with high levels of depression, low quality of life, and female sex. No association was found with the other biological and psychological factors evaluated.

Prevalence of Malnutrition and Nutritional Characteristics of Patients With Inflammatory Bowel Disease.

BACKGROUND AND AIMS: This study sought to determine the prevalence of malnutrition in patients with inflammatory bowel disease, to analyse the dietary beliefs and behaviours of these patients, to study their body composition, to evaluate their muscular strength and to identify the factors associated with malnutrition in these patients. METHODS: This was a prospective, multicentre study. Crohn's disease and ulcerative colitis patients from 30 Spanish centres, from the outpatient clinics, were included. A questionnaire of 11 items was applied to obtain data from patients' dietary behaviour and beliefs. Patients who accepted were evaluated to assess their nutritional status using Subjective Global Assessment and body mass index. Body composition was evaluated through bioelectrical impedance. RESULTS: A total of 1271 patients were included [51% women, median age 45 years, 60% Crohn's disease]. Of these, 333 patients underwent the nutritional evaluation. A total of 77% of patients declared that they avoided some foods to prevent disease relapse. Eighty-six per cent of patients avoided some foods when they had disease activity because of fear of worsening the flare. Sixty-seven per cent of patients modified their dietary habits after disease diagnosis. The prevalence of malnutrition was 16% [95% confidence interval = 12-20%]. In the multivariate analysis, history of abdominal surgery, active disease and avoidance of some foods during flares were associated with higher risk of malnutrition. CONCLUSIONS: The prevalence of malnutrition in inflammatory bowel disease patients was high. We identified some predictive factors of malnutrition. Most of the patients had self-imposed food restrictions, based on their beliefs.

Cost-minimization analysis favours intravenous ferric carboxymaltose over ferric sucrose or oral iron as preoperative treatment in patients with colon cancer and iron deficiency anaemia.

BACKGROUND: Ferric Carboxymaltose (FCM), Iron Sucrose (IS) and Oral Iron (OI) are alternative treatments for preoperative anaemia. OBJECTIVE: To compare the cost implications, using a cost-minimization analysis, of three alternatives: FCM vs. IS vs. OI for treating iron-deficient anaemia before surgery in patients with colon cancer. METHODS: Data from 282 patients with colorectal cancer and anaemia were obtained from a previous study. One hundred and eleven received FCS, 16 IS and 155 OI. Costs of intravenous iron drugs were obtained from the Spanish Regulatory Agency. Direct and indirect costs were obtained from the analytical accounting unit of the Hospital. In the base case mean costs per patient were calculated. Sensitivity analysis and probabilistic Monte Carlo simulation were performed. RESULTS: Total costs per patient were 1827® in the FCM group, 2312® in the IS group and 2101® in the OI group. Cost savings per patient for FCM treatment were 485® compared to IS and 274® compared to OI. A Monte Carlo simulation favoured the use of FCM in 84.7% and 84.4% of simulations when compared to IS and OI, respectively. CONCLUSIONS: FCM infusion before surgery reduced costs in patients with colon cancer and iron-deficiency anaemia when compared with OI and IS.

IBD-related work disability in the community: Prevalence, severity and predictive factors. A cross-sectional study.

BACKGROUND AND AIMS: Data on the prevalence of work disability in patients with inflammatory bowel disease (IBD) are heterogeneous. As most studies have been performed in selected, often severe, IBD patients, the true prevalence of disability in the community remains controversial. The aim of this cross-sectional study was to evaluate the prevalence and severity of disability and its predictive factors in a community-based IBD population. PATIENTS AND METHODS: Patients recorded in the community-based IBD register at the Hospital Universitario de Burgos were contacted. After informed consent they completed a set of questionnaires including demographic, clinical, disability and quality of life data. The statistical study was performed using SPSS 21. RESULTS: A total of 293 patients were included - 151 Crohn's disease (CD), 142 ulcerative colitis (UC), 137 female, mean age: 45 ± 11 years, mean time since diagnosis: 10.6 ± 11 years. Twelve patients (4.1%) had a work-disability pension. In addition, 93 (32%) of all patients had an officially recognized disability degree, which was generally moderate (n = 73, 25%) or severe (N = 16, 5%). Age, time since IBD diagnosis, CD, perianal disease, incontinence, active disease, the need for anti-TNF or psychological treatment, previous surgeries and the number of diagnostic tests and medical visits in the previous year were predictors of disability. Major predictors of qualifying for a disability pension were age, IBD activity, incontinence, need for biological drugs and ostomy. CONCLUSION: Mild to moderate work disability is frequent in IBD. However, only a minority of patients develop severe disability qualifying them for a pension.

The effects of infliximab or adalimumab on vascular endothelial growth factor and angiopoietin 1 angiogenic factor levels in inflammatory bowel disease: serial observations in 37 patients.

BACKGROUND: Infliximab and adalimumab effectiveness might be related with changes in angiogenic factors. The aim of the study was to compare the concentrations of angiogenic proteins in patients with inflammatory bowel disease (IBD) and healthy controls and to analyze changes in the levels during infliximab and adalimumab treatment. METHODS: A prospective case-control study was conducted in 37 patients with IBD starting treatment with infliximab (16 with Crohn's disease and 6 with ulcerative colitis) or adalimumab (15 with Crohn's disease) and 40 control subjects. Four samples were taken from IBD patients, one before each of the first 3 doses of infliximab/adalimumab and one at week 14. Serum levels of vascular endothelial growth factor (VEGF), placental growth factor, angiopoietin 1 (Ang1), angiopoietin 2, and Tie2 were measured using enzyme-linked immunosorbent assay. RESULTS: Patients with IBD had higher VEGF levels than control subjects (511.5 ± 255.6 versus 395.5 ± 256.4; P = 0.05). Patients who achieved remission at the third dose of anti-TNF-alpha had lower VEGF levels at baseline (453.5 ± 250.7 versus 667.5 ± 153.9 pg/mL) and before the second (409.7 ± 217 versus 681.3 ± 350.6 pg/mL) and third (400.5 ± 222.8 versus 630.4 ± 243.1 pg/mL) doses compared with those with no remission (P < 0.05). Ang1 levels decreased before each treatment dose in patients who achieved remission (P < 0.05). High baseline VEGF levels predicted for a poor response to anti-TNF-alpha therapy (area under the receiver operating characteristics curve = 0.8), whereas high Ang1 levels were associated with disease remission (area under the receiver operating characteristics curve = 0.7). Concentrations of angiogenic proteins did not correlate with clinical activity scores. CONCLUSIONS: Circulating VEGF and Ang1 levels decrease after anti-TNF-alpha therapy and may predict response to treatment. Whether these changes are a direct effect of anti-TNF-alpha therapy or a sign of disease improvement remains to be elucidated.

Cost-minimization analysis favours intravenous ferric carboxymaltose over ferric sucrose for the ambulatory treatment of severe iron deficiency.

OBJECTIVE: Intravenous iron is widely used to treat iron deficiency in day-care units. Ferric carboxymaltose (FCM) allows administration of larger iron doses than iron sucrose (IS) in each infusion (1000 mg vs. 200 mg). As FCM reduces the number of infusions required but is more expensive, we performed a cost-minimization analysis to compare the cost impact of the two drugs. MATERIALS AND METHODS: The number of infusions and the iron dose of 111 consecutive patients who received intravenous iron at a gastrointestinal diseases day-care unit from 8/2007 to 7/2008 were retrospectively obtained. Costs of intravenous iron drugs were obtained from the Spanish regulatory agencies. The accounting department of the Hospital determined hospital direct and indirect costs for outpatient iron infusion. Non-hospital direct costs were calculated on the basis of patient interviews. In the pharmacoeconomic model, base case mean costs per patient were calculated for administering 1000 mg of iron per infusion using FCM or 200 mg using IS. Sensitivity analysis and Monte Carlo simulation were performed. RESULTS: Under baseline assumptions, the estimated cost of iron infusion per patient and year was €304 for IS and €274 for FCM, a difference of €30 in favour of FCM. Adding non-hospital direct costs to the model increased the difference to €67 (€354 for IS vs. €287 for FCM). A Monte Carlo simulation taking into account non-hospital direct costs favoured the use of FCM in 97% of simulations. CONCLUSION: In this pharmacoeconomic analysis, FCM infusion reduced the costs of iron infusion at a gastrointestinal day-care unit.
