H elicobacter pylori is a spiral-shaped,gram-negative bacterium that re-sides between the mucous layer and sur-face epithelial cells in the stomach or in-testines.1 It colonizes the gastrointestinallining when the mucosal integrity has beencompromised by environmental factorssuch as increased acid production, phar-maceutical agents (nonsteroidal antiin-flammatory drugs, aspirin, selective sero-tonin reuptake inhibitors), dietary toxins,or stress.2,3 H. pylori infects 30-40% of thepopulation in developed countries like theUS.3 H. pylori infection is more commonin lower socioeconomic conditions and isprevalent in about 80-90% of the popula-tion in developing countries.4 This colo-nization leads to ulcerations in the mucos-al lining and causes peptic ulcer disease inup to 20% of infected individuals.5 Symp-toms of peptic ulcer disease include ab-dominal pain, nausea, reflux symptoms,and vomiting; it is the most commoncause of upper gastrointestinal bleedingand perforation.2 Symptoms and compli-cations associated with peptic ulcer disease lead to job absen-teeism, reduced work productivity, and lower health-relatedquality of life. Direct costs related to outpatient and inpatientvisits and medication costs are a burden to the health-caresystem and to patients.2
One of the main treatment goals for peptic ulcer diseaseis H. pylori eradication.6 Treatment of H. pylori consists oftriple or quadruple therapy that includes antimicrobials andacid suppressive therapy with a proton pump inhibitor, his-
tamine receptor antagonist, and bismuth.3 Table 1 includesthe first-line recommendations for H. pylori eradicationrecommended by the American College of Gastroenterolo-gy.3 Treatment will fail in approximately 10-35% of pa-tients, and H. pylori will remain resulting from several fac-tors, including nonadherence related to adverse effects orcomplicated dosing regimens, high prescription costs, andantibiotic resistance.7,8

OBJECTIVE: To review the literature on the role of probiotics as adjunctive therapyin the treatment of Helicobacter pylori infections.DATA SOURCES: Literature was accessed through MEDLINE (1966-March 2011)using the terms H. pylori, probiotic, Lactobacillus, Bifidobacterium, Saccharomyces,Bacillus clausii, and Propionibacterium. Article references were hand-searched foradditional relevant articles and abstracts.STUDY SELECTION AND DATA EXTRACTION: All English-language articles publishedin full were evaluated. Randomized, double-blind, placebo-controlled trialsassessing the use of probiotics combined with standard eradication therapy of H.pylori infection in adults were included in the review.DATA SYNTHESIS: Various probiotics, including Lactobacillus spp., Saccharomycesspp., Bifidobacterium spp., and B. clausii, reduce adverse effects such as nausea,taste disturbance, diarrhea, and epigastric pain, and increase tolerability of H.pylori eradication therapy. Based on the studies reviewed, probiotics do not affectH. pylori eradication rates. CONCLUSIONS: Probiotics may be beneficial in reducing adverse effects andincreasing tolerability of H. pylori eradication regimens. They may especially behelpful in patients with recurrent H. pylori infection and a history of gastrointestinaladverse effects with antibiotics. Pharmacists can play an important role ineducating patients regarding probiotic use during H. pylori eradication therapy.

Data Sources and Selection
This review examines the role of probiotics in the treat-ment of H. pylori infection. A literature search usingMEDLINE (1966-March 2011) was completed to identifyrandomized, double-blind, placebo-controlled trials pub-lished in full in English assessing the use of probioticscombined with standard eradication therapy of H. pyloriinfection. The search included some of the most commonand familiar strains of probiotics used in gastrointestinaldisorders: Helicobacter pylori, probiotic, Lactobacillus, Bi-fidobacterium, Saccharomyces, Bacillus clausii, and Propi-onibacterium. The search was further limited to adults.Bibliographies of recent review articles and systematic re-views were hand-searched for relevant trials.
Clinical Studies
Four randomized, double-blind, placebo-controlled tri-als assessing the use of probiotics combined with standarderadication therapy of H. pylori infection were identified(Table 2).12-15 In all 4 trials, participants were healthy and,although they were asymptomatic, the results of H. pyloricultures were positive. All trials assessed antibiotic-associ-ated adverse effects and treatment tolerability as the prima-ry outcome. H. pylori eradication rate was the secondaryoutcome in each of the trials.
In the first trial, 60 participants were treated with tripleantibiotic therapy on days 1-7 and Lactobacillus GG on
days 1-14.12 Probiotics significantly improved symptoms,including nausea (10% vs 36.6%; RR 0.3; 95% CI 0.1 to0.9), taste disturbance (23.3% vs 50%; RR 0.5; 95% CI 0.2to 0.9), and diarrhea (3.3% vs 26.6%; RR 0.1; 95% CI 0.1to 0.9); however, epigastric pain (33.3% vs 30%; RR 1.1;95% CI 0.5 to 2.3) did not significantly improve duringeradication treatment. These effects were not seen duringthe week following the completion of antibiotic therapy.Eradication rates did not differ significantly between thegroups (83.3% vs 80%).
In the second trial, 97 individuals were randomized toreceive Lactobacillus GG, Saccharomyces boulardii, Lac-tobacillus acidophilus, Bifidobacterium lactis, or placeboon days 1-14, with H. pylori treatment on days 1-7.13 Probi-otics significantly improved symptoms, including taste dis-turbance (RR 0.15; 95% CI 0.05 to 0.46; p = 0.0027) anddiarrhea (RR 0.16; 95% CI 0.04 to 0.56; p = 0.018); how-ever, nausea (p = 0.75) and epigastric pain (p = 0.7) did notsignificantly improve during H. pylori treatment. These ef-fects were seen during the treatment week and were notmaintained following the completion of antibiotic therapy.All of the differences were noted between the probioticsand placebo. None of the probiotics was superior to anoth-er. Eradication rates were not significantly different amongthe 4 groups receiving probiotics.
In the third trial 47 patients were studied using a milk-based fruit drink containing Lactobacillus GG, Propioni-bacterium, Bifidobacterium, or placebo on days 1-28 andtriple antibiotic therapy days 1-7.14 Probiotics did not sig-nificantly improve symptoms, including nausea (13% vs21%; mean difference 8%; 95% CI 32 to 16), taste dis-turbance (70% vs 67%; mean difference 3%; 95% CI 24to 30), diarrhea (17% vs 8%; mean difference 9%; 95% CI12 to 32), and epigastric pain (17% vs 29%; mean differ-ence 12%; 95% CI 36 to 14).

significantly differ between the groups (91% vs 79%; p =0.42).
In an intention-to-treat analysis in the fourth trial, 114patients were administered B. clausii or placebo on days 1-14 and triple antibiotic therapy on days 1-7.15 The probioticimproved nausea (25.9% vs 50%; RR 0.519; 95% CI 0.31to 0.88), diarrhea (9.3% vs 30.8%; RR 0.301; 95% CI 0.12to 0.76), and epigastric pain (44.4% vs 65.4%; RR 0.68;95% CI 0.48 to 0.97); however, it had no effect on tastedisturbance (53.7% vs 59.6%; RR 0.901; 95% CI 0.65 to1.26) during the first week while patients were receivingantibiotic therapy. The probiotic continued to improve nau-sea during week 2 (14.8% vs 32.7%; RR 0.453; 95% CI0.21 to 0.96). However, this probiotic did not improveeradication rates (72.2% vs 71.15%; p = NS).
Discussion
The majority of the studies on probiotic therapy during H.pylori eradication did not have strong designs. To evaluatethe most robust data, only randomized, double-blind, place-bo-controlled trials of probiotics and H. pylori eradicationtherapy were included in this review. In 3 of the 4 trials, pro-biotics increased tolerability and reduced adverse effects, par-ticularly nausea, taste disturbance, diarrhea, and epigastricpain, of H. pylori eradication therapy.12,13,15 This was true of avariety of probiotic strains such as Lactobacillus spp., Sac-chromyces spp., Bifidobacterium spp., and B. clausii. One tri-al did not find a reduction in adverse effects; however, it wasthe smallest of the 4 trials and the only one to use a milk-based probiotic supplement.14 Probiotics did not appear tohave an effect on the eradication rates in any of the 4 trials.
Strengths of the 4 trials consist of the use of objectivedata such as the urea breath test and serologic assays suchas the enzyme-linked immunosorbent assay to diagnose H.pylori in healthy, asymptomatic study subjects. The ureabreath test has an excellent positive and negative predictivevalue, regardless of H. pylori prevalence. Although quanti-tative antibody testing has very good negative predictivevalue, the positive predictive value depends on H. pyloriprevalence, and is not recommended for use after therapy.The urea breath test and serology were used to confirmeradication between 4 and 7 weeks after eradication thera-py, which adds a limitation to the trials with the use ofserologic assays after treatment, but are still consideredvalid objective measurements in clinical trials. The first tri-al used specific and detailed questionnaires to assess symp-toms, and patients were also provided verbal and printedinstructions on filling in the questionnaires.12 This mostlikely led to increased questionnaire adherence and relia-bility of the adverse effect data. The second trial includedasymptomatic subjects and used a mandatory run-in periodto prevent a confounding factor of previous gastrointestinalsymptoms.13 Myllyluoma and colleagues used fecal recov-
ery of Lactobacillus and Propionibacterium to show ad-herence in the treatment group and probiotic abstinence inthe placebo group.14 The first and fourth trials analyzedsymptoms individually, and categorized them weekly.12,15This provided specific information regarding adverseevents and effective timing of probiotics.
Even though these are well-designed trials, they do havelimitations. They used differing eradication regimens. Twoof the trials12,13 used a tinidazole-based regimen, which isnot considered first-line therapy in the US.3 All 4 trialsused a 7-day eradication regimen, which is shorter than therecommended 10- to 14-day regimens3; this may have hadan effect on eradication rates and tolerability. Small samplesizes further limited the studies. In addition, subjects com-pleted questionnaires and symptom diaries to report ad-verse effects and treatment tolerability, which may haveskewed the results because of the subjective nature of ad-verse effect reporting, and the inevitable variability in pa-tient response to adverse effects. While all 4 trials assessedadherence, rates were not reported. This may be an issuebecause of the high pill burden of H. pylori eradicationtherapy with additional probiotic doses. One trial includedparticipants from a group of educated health-careproviders, which does not necessarily represent the popula-tion most affected by H. pylori disease.12 Adverse effectsmight be tolerated differently in this population, and the di-ets of the participants may be more rich in fruits, vegeta-bles, and dairy compared to subjects in other trials. Noneof the studies controlled for subjects intake of dietary pro-biotics such as yogurt or other probiotic supplements. It isunclear whether any geographic differences existed, sincethe 3 trials that showed improvement in tolerability wereconducted in Italy,12,13,15 whereas the fourth trial was con-ducted in Finland.14 Finally, all trials used different probi-otics.
Conflicting evidence exists regarding the efficacy ofprobiotics for the reduction of adverse effects and increasein tolerability of H. pylori eradication therapies. Some tri-als indicate that probiotics are effective for reducing ad-verse effects and increasing eradication rates of H. pyloritherapy.16,17 Other trials showed increased eradication rates,with increases or no change in adverse effects.18,19 Whilesome trials report probiotics have no effect on adverse ef-fects or eradication rates,20,21 others report that probioticsreduce adverse effects without affecting eradication rates.22
Probiotics may have a role as adjunctive therapy for H.pylori eradication. They have been shown to improve gas-trointestinal adverse effects such as nausea, taste distur-bance, diarrhea, and epigastric discomfort. By reducing theadverse effects, patients may adhere to H. pylori eradica-tion therapy, thereby increasing eradication rates. This issupported by a study that showed the use of a yogurt probi-otic preparation resulted in a higher completion rate thaneradication therapy alone.17 An increase in the eradication

rate of H. pylori during antibiotic therapy may decrease thechance of recurrence and may result in reduced bacterialresistance.
Probiotics are not often used as adjunctive therapy forpatients with H. pylori infections. This provides the phar-macist with an important role in discussing the option ofprobiotic use in combination with H. pylori eradicationtherapy. A pharmacist should, however, take into accountthe economic burden of these products before recommend-ing them. A typical regimen of probiotics would begin inconjunction with the H. pylori eradication therapy and maybe continued for a week following completion of the eradi-cation therapy. Many probiotics are readily available in thecommunity, and choosing an appropriate product could bean important factor in treating the patient. Unfortunately,the products used in these studies are not typically sold inthe US, which makes selecting a probiotic supported byevidence difficult. Even though a specific strain of Lacto-bacillus supported by evidence may not be available in theUS, it may be reasonable to extrapolate the effects of thatstrain to other types of Lactobacillus when product selec-tions are limited. Table 3 contains a noninclusive list ofprobiotic preparations available in the US.
Probiotics are most commonly recommended for use onan outpatient basis to healthy patients without many co-morbid conditions. This population represents most of thepatients in the clinical trials that were reviewed. Probioticsare freely used because of their dietary supplement status,which limits the amount of safety data reported, and also be-cause of their perceived lack of serious complications. How-ever, there have been case reports of fungemias caused bySaccharomyces cerevisiae and S. boulardii with and withoutprobiotic supplementation.23 Patients who acquire invasiveSaccharomyces infections have at least one risk factor, in-cluding intravenous catheter use, intensive care unit hospital-
ization, and immunocompromised status. There have beenother case reports linking Lactobacillus spp. and Bacillussubtilis to invasive bacterial infections in patients taking pro-biotic supplements.24-26 This is contradictory to clinical trialsshowing Lactobacillus to be safe for use in immunocompro-mised populations, but is still an alarming finding. This maybe important to consider when recommending probiotics topatients who might be at a higher risk of acquiring blood-borne infections, especially the immunocompromised or pa-tients with central catheters.
Summary
Probiotics may be beneficial in reducing adverse effectsand increasing tolerability of H. pylori eradication regi-mens. They may especially be helpful in patients with re-current H. pylori and history of gastrointestinal adverse ef-fects with antibiotics. Pharmacists can play an importantrole in educating their patients regarding probiotic use dur-ing H. pylori eradication therapy.

EXTRACTO
OBJETIVO: Revisar la literatura concerniente al rol de los agentesprobiticos en el tratamiento de infecciones con Helicobacter pylori(HP).FUENTE DE DATOS: Se realiz una bsqueda de la literatura en la base dedatos MEDLINE (1966marzo 2011) utilizando los trminosHelicobacter pylori, probitico, Lactobacillus, Bifidobacterium,Saccharomyces, Bacillus clausii, y Propionibacterium. Se revisaron lasreferencias para identificar artculos y extractos relevantes adicionales.SELECCIN DE ESTUDIOS Y EXTRACCIN DE DATOS: Se evaluaron todos losartculos publicados en el idioma ingls. En la revisin se incluyestudios aleatorios, doble ciegos, controlados con placebo que evaluaronel uso de probiticos combinados con tratamientos estandarizados paraerradicacin de HP.SNTESIS DE DATOS: Este artculo repasa la evidencia relacionada con eluso de probiticos como terapia adyuvante para HP. Varios probiticos,incluyendo Lactobacillus spp, Saccharomyces spp., Bifidobacteriumspp., y Bacillus clausii reducen efectos adversos tales como nusea,alteracin del sentido del gusto, diarrea y dolor epigstrico y aumenta latolerancia a los tratamientos para erradicar HP. Segn los estudiosrevisados, los probiticos no alteran la tasa de erradicacin de HP.CONCLUSIONES: Los probiticos pueden ser de beneficio en el tratamientopara erradicar HP al reducir los efectos adversos y aumentar la toleranciaal tratamiento. Los probiticos pueden ser considerados para pacientesque estn recibiendo tratamiento para erradicar HP y para pacientes conHP recurrente e historial de efectos adversos relacionados al tratamientocon antibiticos. Los farmacuticos pueden jugar un papel importante enla educacin de pacientes en el uso de probiticos durante la terapia deerradicacin de HP.

Les articles derfrences ont t revus afin de dceler dautres articles et rsumspertinents.SLECTION DES TUDES ET EXTRACTION DES DONNES: Tous les articlespublis de langue anglaise ont t valus. Les tudes randomises, double insu avec un contrle placebo valuant lutilisation deprobiotiques combins un traitement standard pour lradication delinfection HP chez les adultes ont t inclues dans la revue.SYNTHSE DES DONNES: Cette article revoit les donnes concernantlutilisation des probiotiques pour le traitement adjuvant du HP. Unevarit de probiotiques incluant Lactobacillus spp., Saccharomyces ssp., etBacillus clausii reduisent les effets indsirables tels que les nauses,laltration du got, les diarrhes et la douleur gastrique et amliore la
tolrance au traitement pour lradication du HP. Selon les tudes rvises,les probiotiques ne compromettent pas les taux dradication du HP.CONCLUSIONS: Lutilisation des probiotiques pourrait tre bnfique pourrduire les effets indsirables et augmenter la tolrance au traitement lorsde lutilisation de traitements pour radiquer le HP. Les probiotiquespourraient tre considrs pour lemploi lorsque les patients utilisent untraitement pour radiquer le HP. Les probiotiques pourraient tre utilesspcialement chez les patients qui ont une histoire de rcurrencedinfection HP et des effets indsirables documents avec lesantibiotiques. Les pharmaciens pourraient jouer un rle important danslducation de ces patients concernant lutilisation de probiotiquesdurant leur traitement pour liminer le HP.
