ABSTRACT

Antecedentes: Las recomendaciones de esquemas para erradicar Helicobacter pylori se encuentran ampliamente dis- ponibles. Este es un patógeno de alta prioridad para búsqueda y desarrollo de nuevos y efectivos tratamientos. Objetivo: Descri- bir la respuesta terapéutica con terapia de rescate para infección por H. pylori, Hospital Escuela, Tegucigalpa, diciembre 2016-abril 2017. Métodos: Estudio descriptivo longitudinal retrospectivo en pacientes consecutivos con sintomatología gastrointestinal e in- fección conirmada por H. pylori. Mediante el registro del Servi- cio de Gastroenterología, Departamento de Medicina Interna, se identiicaron pacientes positivos por H. pylori. Se registraron datos sociodemográicos, clínicos y diagnósticos. El tratamiento de res- cate brindado fue, vía oral por 10 días: levoloxacina 500 mg/día, esomeprazol 40 mg dos veces/día, amoxicilina 1 gr dos veces/ día. La conirmación de la erradicación fue realizada 4-8 semanas postratamiento. Se registró información sobre la adherencia al tra- tamiento y los efectos secundarios. Resultados: Se analizaron 30 casos; 56.7% (17) pacientes nuevos y 43.3% (13) pacientes con al menos un fracaso. En el 16.0% (5) no hubo conirmación de erra- dicación; se obtuvo una tasa de erradicación del 72.0% (18/25), IC95% 50.6-87.9; siendo 78.5% (11/14) en pacientes nuevos ver- sus 63.6% (7/11) en fracasos previos, IC95% -9.6-54.0, p=0.318. Discusión: La tasa de erradicación en este grupo de pacientes no fue satisfactoria. Actualmente el tratamiento con levoloxacina es recomendado como terapia de segunda línea o de rescate en regiones con baja o alta resistencia a la claritromicina, aunque la resistencia a quinolonas ha aumentado en los últimos años en va- rios países...(AU)

ABSTRACT

La resistencia bacteriana a ciertos antibióticos condiciona el éxito del tratamiento erradicador de la infección gástrica por Helicobacter pylori y es motivo de creciente preocupación a nivel mundial. Dada la escasa evidencia publicada en Argentina sobre este tema, nuestro objetivo fue investigar factores asociados a la persistencia de H. pylori post-tratamiento antibiótico. Se determinó la frecuencia de fracaso terapéutico en 81 pacientes con gastritis por H. pylori tratados en nuestro Servicio y sometidos al estudio de urea en aire espirado para confirmar la erradicación de la infección. La edad promedio fue 58±12 y 43.2% eran hombres. La frecuencia de fracaso terapéutico fue 17.3%. De los dos esquemas más utilizados, la frecuencia de fracaso fue mayor con claritromicina + amoxicilina que con levofloxacina + amoxicilina (25% vs. 6.6%, p=0.04). Como factores de riesgo investigamos las siguientes variables: edad, género, síntomas, tabaquismo, consumo de anti-inflamatorios, diabetes, obesidad, tipo y duración de tratamiento. En el análisis univariado, el uso de esquemas con claritromicina y el género masculino se asociaron significativamente a persistencia de la infección [OR 4.2 (1.1-15.6) y 5.2 (1.1-26.4)]. En el análisis multivariado, el uso de esquema con claritromicina permaneció asociado al fracaso terapéutico [OR 5.38 (1.1-29.5)]. Concluimos que la inclusión de claritromicina en el esquema terapéutico para la gastritis por H. pylori se asoció a mayor fracaso terapéutico. Este fracaso es atribuible a alta prevalencia de resistencia de H. pylori a ese antibiótico en la población atendida en nuestro hospital y cuestiona las prácticas habituales de tratamiento en nuestro medio.


Antibiotic resistance may hinder the efficacy of eradication therapy against Helicobacter pylori infection and it has become a major concern worldwide. Due to the relatively scarce evidence published in Argentina on this topic, our aim was to describe factors associated with H. pylori persistence after antibiotic treatment. The therapeutic failure rate was described among 81 patients with H. pylori gastritis treated in our Hospital with a post-treatment urea breath test to determine successful eradication. Mean age was 58 ± 12 and 43.2% were male subjects. H. pylori persistence was observed in 17.3% of subjects. Therapeutic failure was more common among patients receiving clarithromycin + amoxicillin therapy that among those receiving levofloxacin + amoxicillin (25% vs. 6.6%, p = 0.04). The following variables were assessed: age, gender, referral symptoms, smoking, anti-inflammatory use, diabetes, obesity, treatment type and duration. Clarithromycin-based therapy and male gender were associated with infection persistence on univariate analysis [OR 4.2 (1.1-15.6) and 5.2 (1.1-26.4)]. On multivariate analysis, clarithromycin-based was associated with infection persistence [5.38 (1.1-29.5)]. We conclude that clarithromycin-based therapy is significantly associated with treatment failure. This failure may be due to an elevated prevalence of H. pylori resistance to clarithromycin in the population under study and raises the question on the utility of such therapeutic alternative.

ABSTRACT

Abstract The aim of this study was to evaluate the effects of adjunct systemic antibiotic treatment with metronidazole (MTZ) and amoxicillin (AMX) in patients receiving non-surgical subgingival debridement (NSD) for peri-implantitis. Forty subjects presenting with at least one implant with severe peri-implantitis were randomized into an experimental group [treated with NSD plus MTZ (400 mg) and AMX (500 mg) three times a day for 14 days] and a control group treated with NSD plus placebo. Clinical parameters and submucosal biofilm profiles were evaluated up to 1 year post-treatment. Overall, both treatments improved clinical parameters over time. At 1 year, mean probing depth (PD), mean clinical attachment (CA) level and proportions of red complex pathogens did not differ significantly between the two groups. In addition, mean PD and CA changes to 1-year posttreatment did not differ significantly between the two groups between baseline and 1-year post-treatment. These results suggest that the addition of MTZ and AMX to the treatment protocol of patients undergoing NSD for with severe peri-implantitis does not improve the clinical and microbiological outcomes of NSD. The fact that half of the implants in both groups did not achieve clinical success (PD < 5 mm, no BoP, no bone loss) suggest that neither of the tested protocols were effective for treating severe peri-implantitis.

ABSTRACT

ABSTRACT Aim To analyze the influence of the -31 C/T polymorphism of the interleukin-1β gene on Helicobacter pylori eradication therapy success in patients with functional dyspepsia. Methods Functional dyspepsia was diagnosed according to the Rome III criteria. All patients underwent upper gastrointestinal endoscopy, and gastric biopsies were obtained at screening and 12 months after randomization (last follow-up visit). Urease test and histological examination were performed to define the H. pylori status. Patients received twice-daily amoxicillin, clarithromycin and omeprazole for 10 days. Genotyping of the interleukin-1beta -31 C/T polymorphism (rs1143627) was performed using polymerase chain reaction-restriction fragment length polymorphism. Results One hundred forty-nine patients received treatment with triple therapy for H. pylori eradication. Only one patient was lost to follow-up, and adherence to study medication was 94.6%. A total of 148 patients (mean age 46.08 ± 12.24 years; 81.8% women) were evaluated for the influence of the interleukin-1beta -31 C/T polymorphism on the outcome of H. pylori eradication therapy. After treatment, bacteria were eradicated in 87% of patients (129/148). Genotype frequencies of the polymorphism were as follows: CC, 38/148 (25.7%); CT, 71/148 (47.9%); and TT, 39/148 (26.4%). Successful eradication rate was 78.9%, 94.4% and 82.1% for the CC, CT and TT genotypes, respectively. The CT genotype was significantly associated with successful H. pylori eradication (p= 0.039). Conclusion This study suggests that the CT genotype of the interleukin-1beta -31 C/T polymorphism plays a role in the successful eradication of H. pylori among patients with functional dyspepsia.

ABSTRACT

Objetivo: avaliar o conhecimento de implantodontistas sobre profilaxia antibiótica para a prevenção de infecções após a cirurgia para instalação de implantes dentários e sua relação com o surgimento de resistência microbiana. Material e métodos: neste estudo transversal, 33 profissionais devidamente registrados no Conselho Regional de Odontologia e atuantes no Estado, os quais responderam a um questionário. Resultados: a maioria dos entrevistados prescreveu antibacterianos em todos os casos, independentemente do estado geral de saúde do paciente, sendo que alguns profissionais ainda insistem em prorrogar a administração no período pós-operatório. Quando questionados sobre essa conduta, afirmaram que prescrevem de forma racional e baseada em evidências. Conclusão: é indispensável a constante atualização dos implantodontistas, prevenindo uma seleção de bactérias resistentes e exposição dos pacientes a efeitos adversos.


Objectives: to evaluate the knowledge regarding antibiotic use to prevent dental infections after implant placement and its relationship with microbial resistance. Material and methods: in the cross-sectional study, 33 practitioners registered in the Regional Council received a survey with questions on this subject. Results: most professionals indicated antibiotics in all cases, regardless of the patient general health condition, being that the medicamentous threrapy was extended after the postoperative period. Interestingly, some stated that this is made on rational basis and evidence-supported manner. Conclusion: it is fundamental to update professionals regarding the use of these drugs since patients can have bacterial resistance and adverse effects.

ABSTRACT

Objective: To analyze the efficacy of therapeutic endoscopy in combination with quadruple therapy in treating bleeding caused by gastric ulcer and investigate the factors inducing rebleeding


Methods: Two hundred and twelve patients with bleeding caused by gastric ulcer who were admitted to Binzhou People's Hospital, Shandong, China between April 2015 and April 2016 were selected as research subjects. The patients were randomly divided into a control group and an experimental group. Patients in the control group were treated by quadruple therapy, while patients in the observation group received therapeutic endoscopy treatment in addition to the same treatment as the control group. The treatment efficacy, adverse reaction, H pylori [Hp] clearance rate and rebleeding were compared between the two groups


Results: The effective rate of the observation group was 98.1%, which was significantly higher than that of the control group [80.2%], and the difference had statistical significance [P<0.05]. The incidence of adverse reactions in the observation group was lower than that in the control group. The Hp clearance rate of the observation group was higher than that of the control group, and the difference had statistical significance [P<0.05]. The multi-factor analysis on rebleeding suggested that whether therapeutic endoscopy was performed or not, hemoglobin level and presence of peptic ulcer stage A1 were independent risk factors


Conclusion: Endoscopic treatment in combination with quadruple therapy is better in the treatment of bleeding caused by gastric ulcer as compared to medical treatment alone. Patients with high-risk factors such as low content of hemoglobin and ulcer at stage A1 should be monitored more carefully to prevent the occurrence of rebleeding

ABSTRACT

La infección por Helicobacter pylori es una de las infecciones crónicas más comunes a nivel mundial y causa importante de enfermedad péptica y cáncer gástrico. Infecta al 50% de la población adulta con mayor prevalencia en América Central/Sur y Asia y al menos dos veces mayor en poblaciones con alta incidencia de cáncer gástrico. Los objetivos de esta investigación fueron identificar la tasa de erradicación de H. pylori con terapia triple estándar y las posibles características asociadas a su erradicación. Se estudió a 119 pacientes con diagnóstico de infección por H. pylori, seleccionados en forma consecutiva de la consulta externa de Gastroenterología del Hospital General San Juan de Dios. Se realizó endoscopia diagnóstica y toma de biopsia gástrica. Se dio terapia triple estándar con lansoprazol, amoxicilina y claritromicina durante 10 días, seguido de 30 días con lansoprazol. Seis semanas después de completado el tratamiento se evaluó el antígeno de H. pylori en heces para determinar si hubo erradicación. La edad promedio de los participantes fue 49.0 años, 81.5% mujeres, 85.7% de área urbana, el síntoma más común fue dispepsia en 86.6%. En el examen post tratamiento el 89.9%, IC 95% [83.0, 94.7] presentó antígeno en heces negativo. No se encontró asociación entre las características de los pacientes con la respuesta al tratamiento. En conclusión, la respuesta a la terapia triple de primera línea se encuentra dentro del rango aceptable para continuar con ese esquema, pero debe mantenerse una evaluación constante por la presencia de posible resistencia.


Infection by Helicobacter pylori is one of the most common chronic infections worldwide and an important cause of peptic disease and gastric cancer. It infects 50% of the adult population with the highest prevalence in Central / South America and Asia and at least twice as high in populations with a high incidence of gastric cancer. The objectives of this research were to identify the eradication rate of H. pylori after first line standard triple therapy and the possible characteristics associated with its eradication. It was studied 119 patients with a diagnosis of H. pylori infection, selected consecutively from the outpatient department of Gastroenterology of the San Juan de Dios General Hospital. Diagnostic endoscopy and gastric biopsy was performed. Standard triple therapy was given with lansoprazole, amoxicillin and clarithromycin for 10 days, followed by 30 days with lansoprazole. Six weeks after the treatment was completed, the H. pylori antigen in feces was evaluated to determine if there was eradication. The average age of the participants was 49.0 years, 81.5% women, 85.7% of urban area, the most common symptom was dyspepsia in 86.6%. In the post-treatment examination 89.9%, 95% CI [83.0, 94.7] presented negative antigen in feces. No association was found between the characteristics of the patients with the response to treatment. In conclusion, the response to first line triple therapy is within the acceptable range to continue with this scheme, but a constant evaluation must be maintained due to the presence of possible resistance.

ABSTRACT

Antecedentes: El píloro doble constituye un hallazgo endoscópico extremadamente raro, siendo más frecuente en pacientes que padecen enfermedad ulcerosa péptica. Corresponde a una comunicación anormal entre el antro gástrico y el bulbo duodenal, que puede llegar a requerir tratamiento quirúrgico. Caso clínico: Mujer de 86 años de edad con antecedentes de diabetes mellitus tipo 2, hipertensión arterial, así como ingesta crónica de AINE, portadora de enfermedad ácido-péptica de larga evolución con poca respuesta al manejo médico con bloqueadores H2, la cual presenta sangrado de tubo digestivo durante 5 días caracterizado por hematemesis y melena, así como pirosis, náuseas, sin pérdida ponderal; por este motivo se realiza endoscopia digestiva alta la cual reporta como hallazgos: gastritis erosiva crónica activa secundaria a AINE y asociada a Helicobacter pylori, así como píloro doble adquirido secundario a enfermedad ácido-péptica, sin evidencia de tumores u otras lesiones asociadas. Se inicia esquema de erradicación para H. pylori con amoxicilina y claritromicina durante 14 días, asociados a inhibidor de bomba de protones durante 6-8 semanas con buena respuesta al manejo médico. Discusión: El píloro doble adquirido es una rara complicación de úlcera péptica que puede ser asociada a otras enfermedades, AINE y a la colonización por H. pylori, por lo tanto el adecuado tratamiento consistirá en la corrección de esos factores.


Background: The double pylorus is an extremely rare endoscopic finding, being more frequent in patients suffering from peptic ulcer disease. It corresponds to an abnormal communication between the gastric antrum and the duodenal bulb, which may require surgical treatment. Clinical case: A 86-year-old woman with a history of type 2 diabetes mellitus, hypertension and chronic NSAID intake, a carrier of long-term peptic acid disease with poor response to medical management with H2 blockers. This presents digestive tube bleeding for 5 days characterized by hematemesis and melena, as well as heartburn, nausea, without weight loss, reason why high digestive endoscopy is performed, which reports as findings: active chronic erosive gastritis secondary to NSAIDs and associated with Helicobacter pylori, as well as acquired double pylorus secondary to peptic acid disease, without evidence of tumors or other associated lesions. Eradication scheme begins for H. pylori with amoxicillin and clarithromycin for 14 days, associated with a proton pump inhibitor for 6-8 weeks with good response to medical management. Discussion: The acquired double pylorus is a rare complication of peptic ulcer disease that can be associated with other diseases, NSAIDs and colonization by H. pylori, therefore the appropriate treatment will consist in the correction of these factors.

ABSTRACT

Background and study aims: Standard sequential treatment for Helicobacter pylori [H. pylori] eradication has less success because of increasing clarithromycin resistance. Extended treatment and bismuth containing regimens were, therefore, investigated


Patients and methods: Consecutive H. pylori-positive patients with dyspepsia were randomly allocated to one of the three sequential regimens: The first group was given lansoprazole 30 mg b.i.d. plus amoxicillin 1 g b.i.d. for the first 5 days, followed by lansoprazole 30 mg b.i.d., clarithromycin 500 mg b.i.d., and metronidazole 500 mg t.i.d. for the second 5 days [standard sequential, SS]. The second group was given the same regimen but for 7 + 7 days instead of 5 + 5 days [extended sequential, ES]. In the third group, colloidal bismuth 600 mg b.i.d. was added to the second regimen for 14 days [extended sequential + bismuth subcitrate, ES + B]. Urea breath test or histology was performed before enrolment and 6 weeks after the end of treatment to detect H. pylori


Results: A total of 280 patients were included in the study. Per-protocol eradication rates were 62% [56/90], 72% [56/78], and 75% [54/72] in patients who received SS, ES, and ES + B regimens, respectively. Moreover, intention-to-treat eradication rates were 53% [56/104], 62% [56/90] and 62% [54/86], respectively. The differences in eradication rates between the groups were not statistically significant


Conclusion: Although prolonging of the sequential treatment to 14 days may be considered, addition of bismuth to the regimen is of no avail

ABSTRACT

Background and study aims: The success rate of Helicobacter pylori [H. pylori] eradication with the classical triple therapy is gradually declining. In this study, we aimed to compare and assess the efficacies of six different eradication regimens including sequential protocols


Patients and methods: Endoscopically confirmed nonulcer dyspepsia patients were enrolled. H. pylori presence was determined either histologically or by a rapid urease test. Treatment-naive patients were randomly assigned to an either one of three 10-day [OAC, OTMB, and OACB] or one of three sequential protocols [OA + OCM, OA + OCMB, and OA + OMDB] [O = omeprazole, A = amoxicillin, C = clarithromycin, T = tetracycline, M = metronidazole, B = bismuth, D = doxycycline]. The eradication was assessed 6-8 weeks after the completion of the treatment by a 14C-urea breath test


Results: In total, 301 patients were included. Fifty-two percent of the participants [n = 157] were female, and the mean age was 44.9 years [range = 18-70]. The intention to treat [ITT] and per protocol [PP] eradication rate for each regimen is as follows: OAC [ITT = 61.2%, PP = 75%], OTMB [83.3%, 87%], OACB [76.5%, 79.6%], OA + OCM [72.3%, 73.9%], OA + OCMB [82.7%, 89.6%], and OA + OMDB [59.3%, 65.3%]. Smoking significantly affected the eradication rate [P = 0.04]


Conclusion: In this study, OTMB and OA + OCMB were significantly superior to the triple therapy and succeeded to reach the eradication rate proposed by the Maastricht consensus [over 80%]. These two bismuth-containing regimens could be considered for first-line therapy in the regions with high clarithromycin resistance

ABSTRACT

Standard triple therapy (TT), used massively as first-line empirical therapy for Helicobacter pylori (H. pylori) eradication, has shown a progressive decrease in its effectiveness, probably due to increasing resistance to clarithromycin. Recent studies in Chile show eradication under 90%, a limit suggested as adequate efficacy. The so-called concomitant therapy (CT) comprising a proton pump inhibitor, amoxicillin, clarithromycin and metronidazole is the non-bismuth first-line therapy most recommended in current guidelines. However, we have no local data to assess the effectiveness of this regimen. The aim of this study was to prospectively evaluate the effectiveness of CT in a group of patients controlled at a private health center in Santiago, Chile. Patients received 40 mg esomeprazole, 1 g amoxicillin, 500 mg clarithromycin and 500 mg metronidazole, every 12 hours, for 14 days. Sixty-six patients were included, of these patients, 36 returned to control. CT was successful in 33/36 patients, corresponding to 92% (95% CI: 82.5-100%, per protocol analysis). The frequency of significant side effects was 25% (mainly diarrhea and abdominal pain) and only one patient discontinued the treatment. In conclusion, 14-days CT therapy is effective to eradicate H. pylori and could be recommended as first-line empirical regimen, at least in the studied population segment and geographical area. Additional studies are necessary to confirm its efficacy in other socioeconomic and/or geographical settings.


La terapia triple estándar (TT), utilizada masivamente como terapia de primera línea empírica para erradicación de Helicobacter pylori (H. pylori) ha mostrado una progresiva disminución de su efectividad, probablemente por resistencia creciente a claritromicina. Los últimos estudios en Chile muestran erradicación bajo 90%, límite sugerido como eficacia adecuada. Esto ha motivado la búsqueda de esquemas alternativos más eficaces, siendo la así llamada terapia concomitante (TC), que consiste en un inhibidor de la bomba de protones, amoxicilina, claritromicina y metronidazol, el esquema sin bismuto más recomendado en guías clínicas recientes. Sin embargo, no contamos con datos locales que evalúen su efectividad. El objetivo del presente estudio fue evaluar prospectivamente la efectividad de TC en un grupo de pacientes controlados en un centro de salud privado de Santiago de Chile. Los pacientes recibieron esomeprazol 40 mg, amoxicilina 1 g, claritromicina 500 mg y metronidazol 500 mg cada 12 h, por 14 días. Se incluyeron 66 pacientes, de los cuales 36 volvieron a control. La TC fue exitosa en 33/36 pacientes, correspondientes al 92% (IC 95%: 82,5-100%; análisis por protocolo). La frecuencia de efectos colaterales significativos fue 25% (principalmente diarrea y dolor abdominal) y sólo un paciente suspendió el tratamiento por esta causa. En conclusión, la TC por 14 días es efectiva para erradicar H. pylori, al menos en el segmento poblacional y área geográfica estudiados y es un esquema empírico que pudiera recomendarse como primera línea en nuestro medio, aunque se requiere confirmar su eficacia en otros grupos poblacionales.

ABSTRACT

Introducción: los antibióticos son medicamentos empleados tanto en pacientes hospitalizados como ambulatorios, sin embargo, son estos últimos los que mayor riesgo de un uso irracional poseen. Objetivo: determinar el consumo total y de un grupo de antibióticos por comunas en Santiago de Cali, durante los años 2010 a 2013.,Métodos: se calculó el tamaño de muestra y se recogió la información de ventas de un grupo de droguerías. Luego se empleó la metodología de la Dosis Diaria Definida por mil habitantes-día, estimando el consumo total y de cada antibiótico para cada comuna y en diferentes unidades de tiempo. De esta forma se calculó: consumo mes a mes de 2010 a 2013, consumo anual ponderado de 2010 a 2013, consumo ponderado de cada mes del año y consumo ponderado por cada comuna. Resultados: el consumo total de antibióticos fue de 4,3 Dosis Diaria Definida por mil habitantes-días, el antibiótico más consumido fue la amoxicilina, para el total el mes de mayor consumo fue marzo de 2011, el año de mayor consumo fue 2011, el mes del año de mayor consumo total de los tres años fue diciembre y la comuna de mayor consumo fue la 22. Conclusión: se identificó el consumo total y por antibióticos, los meses del año y las comunas de mayor consumo(AU)


Introduction: antibiotics are drugs used in inpatient and outpatient care: however, the latter type of patients is the one more likely to irrationally use these drugs. Objective: to determine the total consumption of a group of antibiotics by communes in Santiago de Cali from 2010 to 2013. Methods: the sample size was calculated and sales information was collected from a group of drugstores. The Defined Daily Dose per 1000 inhabitant-days was used, estimating the total consumption and the consumption of each antibiotic for each commune and in various time units. In this way, monthly consumption from 2010 to 2013, weighted annual consumption from 2010 to 2013, weighted consumption of each month of the year and weighed consumption per commune. Results: the total consumption of antibiotics was 4.3 Defined Daily Dose per 1000 inhabitant-days; the most consumed antibiotic was amoxicillin; the month with highest consumption rate was March 2011; the year of highest consumption was 2011, the month of the year with the highest consumption in the three studied years was December and the commune with the highest consumption was the no. 22. Conclusions: this study identified the total consumption and the consumption per antibiotics, the months of the year and the communes of highest consumption of antibiotics(AU)

ABSTRACT

Neisseria meningitidis, a leading cause of bacterial meningitis and other serious infections, is responsible for approximately one-third of cases of bacterial meningitis in the Children's Hospital of Tunis. The serogroup distribution, antibiotic susceptibility and antigenic and molecular characteristics of N. meningitidis isolates were determined in patients aged 3 days-13 years between February 1998 and June 2013. In all 107 invasive strains of N. meningitidis were isolated. Reduced susceptibility to penicillin G was seen in 55.7% of isolates, with a low level of resistance in all cases; 28.4% showed a low level of resistance to amoxicillin. Serogroup B isolates were the most frequent [80.4%], followed by serogroups C [12.2%] and A [5.6%]. Isolates of serogroup A had the same antigenic formula [A:4:P1.9], the same variable regions VR1, VR2 and VR3, and belonged to the same clonal complex [CC5]. Isolates of serogroups B and C were more heterogeneous with several antigenic formulae. The most frequent clonal complex in these isolates was CC35. Serogroup B accounted for a large percentage of our isolates with marked diversity

ABSTRACT

We aimed to evaluate the effectiveness and safety of bismuth-containing quadruple therapy plus postural change after dosing for Helicobacter pylori eradication in gastrectomized patients. We compared 76 gastric stump patients with H. pylori infection (GS group) with 50 non-gastrectomized H. pylori-positive patients who met the treatment indication (controls). The GS group was divided into GS group 1 and GS group 2. All groups were administered bismuth potassium citrate (220 mg), esomeprazole (20 mg), amoxicillin (1.0 g), and furazolidone (100 mg) twice daily for 14 days. GS group 1 maintained a left lateral horizontal position for 30 min after dosing. H. pylori was detected using rapid urease testing and histologic examination of gastric mucosa before and 3 months after therapy. Mucosal histologic manifestations were evaluated using visual analog scales of the updated Sydney System. GS group 1 had a higher prevalence of eradication than the GS group 2 (intention-to-treat [ITT]: P=0.025; per-protocol [PP]: P=0.030), and the control group had a similar prevalence. GS group 2 had a lower prevalence of eradication than controls (ITT: P=0.006; PP: P=0.626). Scores for chronic inflammation and activity declined significantly (P<0.001) 3 months after treatment, whereas those for atrophy and intestinal metaplasia showed no significant change. Prevalence of adverse reactions was similar among groups during therapy (P=0.939). A bismuth-containing quadruple therapy regimen plus postural change after dosing appears to be a relatively safe, effective, economical, and practical method for H. pylori eradication in gastrectomized patients.
