Meta-analysis of the efficacy of proton pump inhibitors for the symptoms of laryngopharyngeal reflux.

The objective of this study was to perform a systematic review and meta-analysis to assess the effectiveness of proton pump inhibitors (PPI) for reflux disease in adult patients with laryngopharyngeal symptoms. A comprehensive search of Cochrane Library, EMBASE, Ovid EBM Reviews, and PubMed was performed for English-language literature about laryngopharyngeal reflux (LPR), in September 2014. The papers were filtered using pre-defined inclusion and exclusion criteria. Eight papers were identified and included in this meta-analysis. The sample comprised a pooled total of 370 patients, of which 210 and 160 patients took PPIs and placebo, respectively. The difference between PPIs and placebo groups in overall improvement of symptoms in adult patients with LPR was not statistically significant (RR=1.22; 95%CI=0.93-1.58; P=0.149). The difference in cough improvement was also not significant between PPIs and placebo groups (RR=0.65; 95%CI=0.30-1.41; P=0.279).

Randomised clinical trial: daily pantoprazole magnesium 40 mg vs. esomeprazole 40 mg for gastro-oesophageal reflux disease, assessed by endoscopy and symptoms.

BACKGROUND: Pantoprazole magnesium (pantoprazole-Mg) may display extended inhibition of the proton pump with the potential for improved clinical efficacy in gastro-oesophageal reflux disease (GERD). AIM: To compare the efficacy of pantoprazole-Mg and esomeprazole in GERD. METHODS: Gastro-oesophageal reflux disease (Los Angeles grades A-D) patients were randomised to 4 weeks of treatment with pantoprazole-Mg (n = 290) or esomeprazole (n = 288), both 40 mg once daily, in this multicentre (14 Brazilian sites in 9 cities), double-blind study, with an additional 4 weeks' treatment in nonresponding patients. Severity of oesophagitis (at endoscopy) and GERD-related symptoms (ReQuest-GI) were assessed. The primary end point was the proportion of patients in complete remission (ReQuest-GI score <1.73 plus endoscopic healing) at week 4. RESULTS: Complete remission occurred in 61% of patients in each treatment group at 4 weeks (primary endpoint) and in 81% and 79% of patients in the pantoprazole-Mg and esomeprazole groups at 8 weeks, with no significant differences. Mucosal healing rates were high and not significantly different. At 8 weeks, symptom relief with pantoprazole-Mg was significantly greater than that with esomeprazole (91.6% vs. 86.0%, P = 0.0370) because of continued improvement in symptoms with pantoprazole-Mg from week 4 to week 8 (P = 0.0206). CONCLUSIONS: Pantoprazole-Mg 40 mg was at least as effective as esomeprazole 40 mg for complete remission and the mucosal healing rate was high. Symptom relief with pantoprazole-Mg continued to improve from 4 to 8 weeks and was greater than that with esomeprazole at week 8, suggesting an extended period of treatment effect (ClinicalTrials.gov identifier: NCT01132638).

Association of CYP2C19 polymorphisms and lansoprazole-associated respiratory adverse effects in children.

OBJECTIVE: To determine whether cytochrome P450 (CYP)2C19 haplotype associates with lansoprazole-associated adverse event frequency. STUDY DESIGN: Respiratory adverse events from a clinical trial of lansoprazole in children with asthma were analyzed for associations with extensive or poor metabolizer (PM) phenotype based on CYP2C19 haplotypes. Carriers of CYP2C19*2, *3, *8, or *9 alleles were PMs; carriers of 2 wild-type alleles were extensive metabolizers (EMs). Plasma concentrations of lansoprazole were determined in PM and EM phenotypes. RESULTS: The frequency of upper respiratory infection among PMs (n = 45) was higher than that among EMs (n = 91), which in turn was higher than that in placebo subjects (n = 135; P = .0039). The frequency of sore throat (ST) was similarly distributed among EMs and PMs (P = .0015). The OR (95% CI) for upper respiratory infections in PMs was 2.46 (1.02-5.96) (P = .046); for EMs, the OR (95% CI) was 1.55 (0.86-2.79). The OR (95% CI) for ST in EMs and PMs was 2.94 (1.23-7.05, P = .016) vs 1.97 (1.09-3.55, P = .024), respectively. Mean ± SD plasma concentrations of lansoprazole were higher in PMs than in EMs: 207 ± 179 ng/mL vs 132 ± 141 ng/mL (P = .04). CONCLUSIONS: Lansoprazole-associated upper respiratory infections and ST in children are related in part to CYP2C19 haplotype. Our data suggest that lansoprazole-associated adverse events in children may be mitigated by adjusting the conventional dose in PMs. Additional studies are required to replicate our findings.

Association of a probiotic to a Helicobacter pylori eradication regimen does not increase efficacy or decreases the adverse effects of the treatment: a prospective, randomized, double-blind, placebo-controlled study.

BACKGROUND: The treatment for the eradication of Helicobacter pylori (H. pylori) is complex; full effectiveness is rarely achieved and it has many adverse effects. In developing countries, increased resistance to antibiotics and its cost make eradication more difficult. Probiotics can reduce adverse effects and improve the infection treatment efficacy.If the first-line therapy fails a second-line treatment using tetracycline, furazolidone and proton-pump inhibitors has been effective and low cost in Brazil; however it implies in a lot of adverse effects. The aim of this study was to minimize the adverse effects and increase the eradication rate applying the association of a probiotic compound to second-line therapy regimen. METHODS: Patients with peptic ulcer or functional dyspepsia infected by H. pylori were randomized to treatment with the furazolidone, tetracycline and lansoprazole regimen, twice a day for 7 days. In a double-blind study, patients received placebo or a probiotic compound (Lactobacillus acidophilus, Lactobacillus rhamnosus, Bifidobacterium bifidum and Streptococcus faecium) in capsules, twice a day for 30 days. A symptom questionnaire was administered in day zero, after completion of antibiotic therapy, after the probiotic use and eight weeks after the end of the treatment. Upper digestive endoscopy, histological assessment, rapid urease test and breath test were performed before and eight weeks after eradication treatment. RESULTS: One hundred and seven patients were enrolled: 21 men with active probiotic and 19 with placebo plus 34 women with active probiotic and 33 with placebo comprising a total of 55 patients with active probiotic and 52 with placebo. Fifty-one patients had peptic ulcer and 56 were diagnosed as functional dyspepsia. The per-protocol eradication rate with active probiotic was 89.8% and with placebo, 85.1% (p=0.49); per intention to treat, 81.8% and 79.6%, respectively (p=0.53). The rate of adverse effects at 7 days with the active probiotic was 59.3% and 71.2% with placebo (p=0.20). At 30 days, it was 44.9% and 60.4%, respectively (p=0.08). CONCLUSIONS: The use of this probiotic compound compared to placebo in the proposed regimen in Brazilian patients with peptic ulcer or functional dyspepsia showed no significant difference in efficacy or adverse effects.

Gastroprotective effect and cytotoxicity of abietane diterpenes from the Chilean Lamiaceae Sphacele chamaedryoides (Balbis) Briq.

OBJECTIVES: The aim of this report was to isolate, identify and assess the gastroprotective effect and cytotoxicity of abietane diterpenes from the Chilean medicinal plant Sphacele chamaedryoides (Balbis) Briq. (Lamiaceae). METHODS: The isolated compounds were identified by spectroscopic means. The gastroprotective effect of the compounds was studied on the HCl/EtOH-induced gastric lesions model in mice. The cytotoxicity of the compounds was assessed on human normal lung fibroblasts (MRC-5) and gastric adenocarcinoma cells (AGS). KEY FINDINGS: From the aerial parts of the plant, five phenolic and five p-quinone abietanes, the sesquiterpene spathulenol and two flavonoids were obtained. The main diterpene from the plant was carnosol (7:). Lansoprazole at 20 mg/kg reduced gastric lesions by 64.7% (P < 0.01), being statistically similar to carnosol at doses of 10 and 20 mg/kg; the percent lesion reduction with 7: at 5 mg/kg was 49.3%. At a single oral dose of 5 mg/kg, the diterpenes bearing a p-quinone moiety - 6,7-dehydroroyleanone (1), royleanone (2), 7,20-epoxyroyleanone (3), taxoquinone (5) and horminone (6) - presented a gastroprotective effect of 54.4, 70.8, 65.0, 35.8 and 52.7%, respectively. Of the C-7 hydroxy derivatives, the activity was much lower for the 7beta-OH isomer. The phenolic diterpenes 7 and 7-oxo-11,12,14-trihydroxy-8,11,13-abietatrien-20-al (8) inhibited gastric lesions by 49.3 and 53.0%, respectively. Royleanone (2), 7,20-epoxyroyleanone (3), horminone (6), 8 and spathulenol proved to be cytotoxic with IC50 values in the range of 11-67 microm. The selective cytotoxicity of compounds 1 (IC50: 61 and 366 microm) and 5 (IC50: 310 and 27 microm) against AGS cells and fibroblasts, respectively, merit additional studies. CONCLUSIONS: All the abietanes obtained from S. chamaedryoides present either one or two phenolic OH groups, a quinone system, or both. Several compounds present in the plant showed higher gastroprotective effect than lansoprazole. The cytotoxic effect of most compounds was found at fairly high concentrations and lacked cell specificity. Further studies are required using different tumour cell lines and viability/proliferation assays to assess the specificity of the isolated compounds. The selective cytotoxicity of compounds 1 and 5 against AGS cells and fibroblasts, respectively, merit additional studies.

Ranitidine is unable to maintain gastric pH levels above 4 in septic patients.

PURPOSE: The study aimed to evaluate whether ranitidine and pantoprazole are able to maintain gastric pH >or=4 in septic patients. MATERIALS AND METHODS: Twenty intensive care unit patients from a university teaching hospital with sepsis were included in this study. Ten patients received ranitidine (50 mg as an intermittent bolus 3 times a day) and 10 received pantoprazole (40 mg as an intermittent bolus twice a day). Gastric pH was measured continuously for 48 hours. Endoscopy of the upper digestive tract, gastric biopsy, and investigation for Helicobacter pylori were carried out before and at the end of the study. RESULTS: pH values >or=4 were maintained for 46.27% +/- 38.21% and 81.57% +/- 19.65% of study time in the ranitidine and pantoprazole groups, respectively (P = .04). CONCLUSIONS: Intravenous ranitidine was unable to maintain gastric pH above 4 in septic patients. All cases in the ranitidine group in whom pH remained above 4 had gastric hypotrophy or atrophy. Pantoprazole successfully maintained pH levels above 4.

Neither genotype nor the gastric colonization site of Helicobacter pylori are predictive factors for the development of erosive esophagitis in patients with peptic ulcer disease, 1 year after eradication.

CONTEXT: Whether Helicobacter pylori infection is a protective or predisposing factor for the development of gastroesophageal reflux disease remains controversial. The most virulent strains, such as those expressing the cytotoxin-associated gene A (CagA), and the site of gastric colonization have been correlated with the prevention or development of esophagitis. AIM: To determine the incidence of erosive esophagitis following eradication of H. pylori in patients with peptic ulcer disease and to evaluate the association of erosive esophagitis with virulent strains of H. pylori and the site of gastric colonization. METHODS: Triple therapy with lansoprazole, amoxicillin and clarithromycin was administered to 159 patients with peptic ulcer disease. Endoscopy, histopathology, urease and carbon-14 urea breath tests were performed prior to treatment, at 3 months and 1 year following treatment. Genotyping of H. pylori strains using polymerase chain reaction was performed separately on samples from the corpus and antrum. RESULTS: One year after treatment, 148 successfully treated patients were reevaluated. Twenty-eight patients (19%) had erosive esophagitis, classified as Los Angeles grade A in 24 and B in 4. The samples taken from the corpus were CagA-positive in 18 patients (64%), while the samples taken from the antrum were CagA-positive in 21 patients (75%). CONCLUSIONS: The incidence of erosive esophagitis in peptic ulcer patients who had their H. pylori eradicated was 19%. No correlation was found between the gastric site colonized by H. pylori or strains expressing CagA and the prevention or development of erosive esophagitis in patients with peptic ulcer disease, 1 year after infection eradication.

[Eosinophilic esophagitis: report of three cases]. / Esofagitis eosinofílica en niños: Características clínicas y endoscópicas.

Eosinophilic esophagitis in adults (EE) is a disease of unknown cause, characterized by symptoms such as reflux and dysphagia that traditionally do not respond to antacid treatment. It affects mostly young men with a strong personal or familial history of atopy asthma and allergies. We report three male patients aged 10, 14 and 15 years, all with symptoms of dysphagia, two of them with chest pain caused by spasm of the esophagus, with heterogeneous endoscopic findings which included from leucoplakia to stenosis that needed endoscopic dilatation. All of them had abnormal findings in immunity studies (prick test or IgE levels). They received treatment based on diet measures, acid suppression and leukotriene inhibitors, with satisfactory clinical, endoscopic and histological response. EE should be suspected in children and adults with esophageal symptoms and personal or family history of allergy and asthma.

Efficacy of a 7-day course of furazolidone, levofloxacin, and lansoprazole after failed Helicobacter pylori eradication.

BACKGROUND: Increasing resistance to clarithromycin and nitroimidazole is the main cause of failure in the Helicobacter pylori eradication. The ideal retreatment regimen remains unclear, especially in developing countries, where the infection presents high prevalence and resistance to antibiotics. The study aimed at determining the efficacy, compliance and adverse effects of a regimen that included furazolidone, levofloxacin and lansoprazole in patients with persistent Helicobacter pylori infection, who had failed to respond to at least one prior eradication treatment regimen. METHODS: This study included 48 patients with peptic ulcer disease. Helicobacter pylori infection was confirmed by a rapid urease test and histological examination of samples obtained from the antrum and corpus during endoscopy. The eradication therapy consisted of a 7-day twice daily oral administration of lansoprazole 30 mg, furazolidone 200 mg and levofloxacin 250 mg. Therapeutic success was confirmed by a negative rapid urease test, histological examination and 14C- urea breath test, performed 12 weeks after treatment completion. The Chi-square method was used for comparisons among eradication rates, previous treatments and previous furazolidone use. RESULTS: Only one of the 48 patients failed to take all medications, which was due to adverse effects (vomiting). Per-protocol and intention-to-treat eradication rates were 89% (95% CI- 89%-99%) and 88% (88-92%), respectively. Mild and moderate adverse effects were reported by 41 patients (85%). For patients with one previous treatment failure, the eradication rate was 100%. Compared to furazolidone-naïve patients, eradication rates were lower in those who had failed prior furazolidone-containing regimen(s) (74% vs. 100%, p = 0.002). CONCLUSION: An empiric salvage-regimen including levofloxacin, furazolidone and lansoprazole is very effective in the eradication of Helicobacter pylori, particularly in patients that have failed one prior eradication therapy.

Multicenter, double-blind, randomized, placebo-controlled trial assessing the efficacy and safety of proton pump inhibitor lansoprazole in infants with symptoms of gastroesophageal reflux disease.

OBJECTIVE: To assess the efficacy and safety of lansoprazole in treating infants with symptoms attributed to gastroesophageal reflux disease (GERD) that have persisted despite a >or= 1-week course of nonpharmacologic management. STUDY DESIGN: This multicenter, double-blind, parallel-group study randomized infants with persisting symptoms attributed to GERD to treatment with lansoprazole or placebo for 4 weeks. Symptoms were tracked through daily diaries and weekly visits. Efficacy was defined primarily by a >or= 50% reduction in measures of feeding-related crying and secondarily by changes in other symptoms and global assessments. Safety was assessed based on the occurrence of adverse events (AEs) and clinical/laboratory data. RESULTS: Of the 216 infants screened, 162 met the inclusion/exclusion criteria and were randomized. Of those, 44/81 infants (54%) in each group were responders--identical for lansoprazole and placebo. No significant lansoprazole-placebo differences were detected in any secondary measures or analyses of efficacy. During double-blind treatment, 62% of lansoprazole-treated subjects experienced 1 or more treatment-emergent AEs, versus 46% of placebo recipients (P= .058). Serious AEs (SAEs), particularly lower respiratory tract infections, occurred in 12 infants, significantly more frequently in the lansoprazole group compared with the placebo group (10 vs 2; P= .032). CONCLUSIONS: This study detected no difference in efficacy between lansoprazole and placebo for symptoms attributed to GERD in infants age 1 to 12 months. SAEs, particularly lower respiratory tract infections, occurred more frequently with lansoprazole than with placebo.

Failure of Helicobacter pylori treatment after regimes containing clarithromycin: new practical therapeutic options.

UNLABELLED: Failure of Helicobacter pylori treatment is a growing problem in daily practice. AIM: To evaluate the efficacy of two new regimes as second-line options in a randomized and prospective study. METHODS: Patients in whom a first eradication regime containing clarithromycin had failed were included. After performing gastroscopy and a 13C-urea breath test (UBT), the patients were randomized to receive a combination of 20 mg of rabeprazole, 500 mg of levofloxacin, and 200 mg (two tablets) of furazolidone administered once daily for 10 days (RLF) or the combination of 20 mg of rabeprazole, 120 mg (two tablets) of bismuth subcitrate, 100 mg of doxycycline, and 200 mg of furazolidone, administered twice daily for 10 days (RBDF). Clinical examinations and new UBT were performed 60 days after therapy. RESULTS: Sixty patients were included (mean age, 46 years, 57% females). Two patients were excluded: one because of adverse effects and another as a result of protocol violation. Compliance was similar in both groups (90% took all medications correctly). Side-effects (96% mild) were observed in 87% of the patients and were comparable between groups, except diarrhea, which was more frequent in group RLF (p= .025). Intention-to-treat cure rates were 77% (95% confidence interval (CI): 62-93%) in the RLF group and 83% (95% CI: 68-97%) in the RBDF group (p= .750). Per-protocol cure rates were 80% (95% CI: 65-95%) in the RLF group and 82% (95% CI: 67-96%) in the RBDF group (p= 1.0). CONCLUSIONS: Both once-daily triple (rabeprazole, levofloxacin, and furazolidone) and twice-daily quadruple therapy (rabeprazole, bismuth subcitrate, doxycycline, and furazolidone) for 10 days achieved encouraging results. Subsequent studies should be performed to evaluate antibiotic resistance, doses, dosing intervals, duration of treatment, and safety of these two regimes.

Evaluation of pantoprazol treatment response of patients with asthma and gastroesophageal reflux: a randomized prospective double-blind placebo-controlled study.

OBJECTIVES: To determine the effect that the treatment of GERD has on the clinical management, as well as the respiratory function, of patients with asthma and to evaluate the clinical characteristics of this group of patients. METHODS: Patients with asthma and concomitant GERD, documented using 24 h pH-metry, were evaluated by means of quality of life questionnaires, as well as questionnaires related to respiratory and digestive symptoms. In addition, esophageal manometry, spirometry and the determination of peak expiratory flow were also performed prior to and after the study. Forty-nine individuals who were diagnosed with GERD by means of 24 h esophageal pH-metry were selected and participated in a clinical randomized double-blind placebo-controlled study, involving the administration of 40 mg/day of pantoprazol for 12 consecutive weeks. RESULTS: Forty-four individuals completed the study (n = 22 per group). There was significant improvement in the scores for respiratory symptoms and quality of life only in the group that received pantoprazol (p = 0.01 and p = 0.001, respectively). No respiratory function parameters changed in either group. CONCLUSIONS: In this study, the effective treatment of GERD improved patient quality of life, and the symptoms of asthma significantly decreased in the group that received the medication. There were no changes in pulmonary function parameters.

Helicobacter pylori infection and thrombocytopenia: a single-institution experience in Mexico.

The association between gastrointestinal H. pylori infection and thrombocytopenia was studied in a single institution in Mexico, over a 5-year period. In 99 individuals with H. pylori infection, the prevalence of thrombocytopenia was 14%, whereas in 23 consecutive patients with chronic refractory thrombocytopenic purpura, the prevalence of H. pylori infection was 60%, this figure being similar to that informed in the general population of Mexico (66%); the association between thrombocytopenia and H. pylori infection was not significant. In 14 patients who were found to have both thrombocytopenia and H. pylori infection, eradication treatment was given and the platelet count recovered in three. It is not still clear if detection of H. pylori infection should be routinely included in the initial workup of chronic thrombocytopenia.

Characteristics of children receiving proton pump inhibitors continuously for up to 11 years duration.

OBJECTIVE: To characterize those pediatric patients who receive long-term proton pump inhibitors (PPIs) and to determine the safety of long-term use of PPIs in this population. STUDY DESIGN: Patient databases were screened for long-term PPI use, defined as more than 9 months of continuous prescription, between 1989 and 2004. RESULTS: The median duration of PPI use in the 166 patients in the study group was 3 years (range, 0.75 to 11.25 years). A total of 80 patients used PPIs for 3 to 11 years duration; 35 of these for more than 5 years, and 15 for more than 8 years. Mean age at initial prescription was 7.8 years. At least 1 gastroesophageal reflux disease (GERD)-predisposing disorder was present in 79% of the patients; the major disorders were neuromotor (in 66%) and esophageal atresia (in 14.5%). No GERD-predisposing disorder was present in 35 patients (21%). Endoscopic findings included hiatal hernia in 39% and histologically proven Barrett's esophagus in 4.8%. Omeprazole was used in 90% of the patients; lansoprazole, in 7%. Six adverse reactions seen in 4 patients were potentially related to PPI (nausea and diarrhea, skin rash, agitation, and irritability). CONCLUSIONS: Children with underlying GERD-predisposing disorders compose the majority of long-term PPI users. Few adverse reactions to these drugs occur, and discontinuation of the drug is seldom indicated. These preliminary data suggest that PPIs may be efficacious and safe for continuous use for up to 11 years' duration in children.

Treatment of gastroesophageal reflux disease.

OBJECTIVES: To review the literature on the treatment of gastroesophageal reflux disease (GERD) with emphasis on pharmacological aspects. To identify particularities of pharmacological treatment of esophageal and extraesophageal manifestations of the disease. SOURCES: Electronic search of the PubMed/MEDLINE and Cochrane Collaboration databases. Controlled and randomized studies published since 2000 and reviews representing consensus positions and directives published within the last 10 years were identified. SUMMARY OF THE FINDINGS: The drugs currently available for the treatment of GERD do not act in the primary mechanism of the disease, i.e. transitory relaxation of the lower esophageal sphincter. Pharmacological treatment of GERD with symptoms or with esophageal injury is based on the suppression of acid secretion, particularly with proton pump inhibitors. When the hyperreactivity of the lower airways coexists with esophageal GERD symptoms, suppression of acid secretions should be of benefit in managing the respiratory disease in the presence of a causal relationship; however, this is not usual. When esophageal symptoms are not present, esophageal 24-hour pH study should be carried out prior to starting pharmacological treatment for GERD. Improvement of respiratory symptoms may be delayed with relation to esophageal symptoms. It is common for GERD to recur and pharmacological treatment should be repeated or continued indefinitely, depending on clinical presentation of the disease. CONCLUSIONS: The strategies that have been proposed for the pharmacological treatment of GERD in children are primarily based on studies of case series or on studies with adults. There have been very few controlled and randomized studies in children. Undertaking a greater number of these studies might reinforce existing aspects or establish new aspects of management.

Evaluation of health-related quality of life in gastroesophageal reflux disease patients before and after treatment with pantoprazole.

Gastrooesophageal reflux disease (GERD) is highly prevalent in the Western world but its true population prevalence is difficult to estimate without a validated instrument to detect it. The evaluation of health-related quality of life (HRQoL) is an useful tool in this assessment. The aims of this study are to translate and validate a GERD specific HRQoL questionnaire and evaluate HRQoL in a Brazilian population before and after GERD treatment. GERD patients with typical symptoms and Los Angeles Classes A to C esophagitis were included in the study. Two HRQoL questionnaires and upper digestive endoscopy were performed before and after 6 weeks treatment with pantoprazole 40 mg/day followed by 80 mg/day for another 8 weeks if healing did not occur. A generic (SF-36) and one disease-specific questionnaire (GERD score) were used. The latter was translated and validated for Brazilian Portuguese. From January 2002 to December 2003, 100 patients were enrolled. Of these, 78 patients were evaluated in a per protocol analysis (35 men, mean age: 40 years). The translated questionnaire (Brazilian GERD Score, BGERDS) demonstrated adequate psychometric properties (validity, responsiveness and reliability). SF-36 and BGERDS domains significantly improved after treatment (P < 0.01 and P < 0.001 respectively). The BGERDS was shown to be valid and reliable. Patients with esophagitis showed an impaired HRQoL that improved or normalized after treatment with pantoprazole.
