Omeprazole prescriptions for older adults in health care units in Curitiba, Brazil: an analysis based on Beers Criteria / Prescrições de omeprazol para idosos em unidades de saúde de Curitiba: análise segundo os Critérios de Beers

OBJECTIVE: To evaluate omeprazole prescriptions for older adults based on the Beers Criteria, with an analysis of indications and duration of use longer than eight weeks. METHODS: In this retrospective cross-sectional study, data were collected from the electronic medical records of older adults with an omeprazole prescription seen at two health care units in Curitiba, Brazil, between June and August 2019. Data were subjected to descriptive statistical analysis, Student t and χ2 tests. RESULTS: Medical records of 386 patients were analyzed, and 69.95% were female. The mean age was 71 (SD, 8.15) years. Most patients had incomplete primary education (50.52%) and income level ranging from one to two Brazilian minimum monthly wages (39.90%). No indication for omeprazole prescription was found in 23.83% of medical records. Use longer than eight weeks was predominant for all indications in 96.60% of medical records. Duration of use more extended than the Beers Criteria recommendation was independent of sex (p = 0.327), education (p = 0.805), and income level (p = 0.629). A relationship between polypharmacy and long-term drug use was demonstrated (p < 0.001). CONCLUSION: The results of this study suggest the need for periodic review of omeprazole prescriptions considering deprescribing when they appropriate.

OBJETIVO: Avaliar as prescrições de omeprazol para idosos de acordo com os Critérios de Beers, por meio das indicações e do tempo de uso do medicamento por período superior a oito semanas. METODOLOGIA: Estudo transversal, retrospectivo, no qual foram coletados dados dos prontuários eletrônicos de idosos com prescrição de omeprazol atendidos entre junho e agosto de 2019 em duas unidades de saúde em Curitiba. Os dados foram submetidos à análise estatística descritiva e aos testes t de Student e do χ2 . RESULTADOS: Foram analisados prontuários de 386 usuários, sendo 69,95% do sexo feminino. A média de idade foi de 71 anos (DP, 8,15). A maioria dos usuários tem ensino fundamental incompleto (50,52%) e faixa de renda de um a dois salários mínimos (39,90%). Não foi encontrada a indicação para a prescrição de omeprazol em 23,83% dos prontuários. O uso por período superior a oito semanas foi predominante, para todas as indicações, em 96,60% dos prontuários. Demonstrou-se que o tempo de uso superior ao recomendado nos Critérios de Beers independe do sexo (p = 0,327), da escolaridade (p = 0,805) e da faixa de renda (p = 0,629). Evidenciou-se a relação entre polifarmácia e uso do medicamento por períodos prolongados (p < 0,001). CONCLUSÃO: Os resultados deste estudo apontam para a necessidade de revisão periódica das prescrições de omeprazol, considerando-se a desprescrição quando apropriado.

Pharmaceutical intervention in the rational use of intravenous omeprazole / Intervenção farmacêutica no uso racional de omeprazol intravenoso

ABSTRACT Objective: To describe the pharmaceutical interventions of a vertical clinical pharmacy service to promote the rational use of intravenous omeprazole. Methods: A prospective and descriptive study carried out at a university hospital in the Midwestern Region of Brazil, from November 2014 to May 2015. The service consisted of the analysis of adequacy of the route of administration of omeprazole in relation to the clinical conditions of the patient, as well as the use of the appropriate diluent. Interventions were recorded in medical records and subsequently evaluated for acceptance. Results: A total of 770 prescriptions were evaluated. Interventions related to diluent replacement were more accepted (p<0.001), and surgeons were the specialty that used the intravenous route inappropriately (p<0.001). Conclusion: Although partially accepted, pharmaceutical interventions could contribute to improve patient safety, since they allowed the use of a safer route of administration.

RESUMO Objetivo: Descrever as intervenções farmacêuticas de um serviço farmacêutico clínico vertical, para a promoção do uso racional do omeprazol intravenoso. Métodos: Estudo prospectivo e descritivo realizado em um hospital universitário da região Centro-Oeste do Brasil, no período de novembro de 2014 a maio de 2015. O serviço consistia na análise da adequabilidade da via de administração do omeprazol em relação às condições clínicas do paciente, bem como a utilização do diluente adequado. As intervenções eram registradas em prontuário e, posteriormente, avaliadas quanto à aceitação. Resultados: Foram avaliadas 770 prescrições. As intervenções relacionadas à substituição do diluente foram mais aceitas (p<0,001), e os cirurgiões foram a especialidade que utilizou a via intravenosa de maneira inadequada (p<0,001). Conclusão: Embora parcialmente aceitas, as intervenções farmacêuticas puderam contribuir com a melhoria da segurança dos pacientes, uma vez que permitiram a utilização de uma via de administração mais segura.

Sintomas persistentes ao tratamento com inibidor da bomba de prótons são devidos à doença do refluxo gastroesofágico refratária ou decorrentes de outras afecções? / Are the persistent symptoms to proton pump inhibitor therapy due to refractory gastroesophageal reflux disease or to other disorders?

ABSTRACT BACKGROUND: Gastroesophageal reflux disease (GERD) is a clinical condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Transient lower esophageal sphincter relaxation is the main pathophysiological mechanism of GERD. Symptoms and complications can be related to the reflux of gastric contents into the esophagus, oral cavity, larynx and/or the lung. Symptoms and other possible manifestations of GERD are heartburn, regurgitation, dysphagia, non-cardiac chest pain, chronic cough, chronic laryngitis, asthma and dental erosions. The proton pump inhibitor (PPI) is the first-choice drug and the most commonly medication used for the treatment of GERD. The most widespread definition of Refractory GERD is the clinical condition that presents symptoms with partial or absent response to twice-daily PPI therapy. Persistence of symptoms occurs in 25% to 42% of patients who use PPI once-daily and in 10% to 20% who use PPI twice-daily. OBJECTIVE: The objective is to describe a review of the current literature, highlighting the causes, diagnostic aspects and therapeutic approach of the cases with suspected reflux symptoms and unresponsive to PPI. CONCLUSION: Initially, the management of PPI refractoriness consists in correcting low adherence to PPI therapy, adjusting the PPI dosage and emphasizing the recommendations on lifestyle modification change, avoiding food and activities that trigger symptoms. PPI decreases the number of episodes of acid reflux; however, the number of "non-acid" reflux increases and the patient continues to have reflux despite PPI. In this way, it is possible to greatly reduce greatly the occurrence of symptoms, especially those dependent on the acidity of the refluxed material. Response to PPI therapy can be evaluated through clinical, endoscopic, and reflux monitoring parameters. In the persistence of the symptoms and/or complications, other causes of Refractory GERD should be suspected. Then, diagnostic investigation must be initiated, which is supported by clinical parameters and complementary exams such as upper digestive endoscopy, esophageal manometry and ambulatory reflux monitoring (esophageal pH monitoring or esophageal impedance-pH monitoring). Causes of refractoriness to PPI therapy may be due to the true Refractory GERD, or even to other non-reflux diseases, which can generate symptoms similar to GERD. There are several causes contributing to PPI refractoriness, such as inappropriate use of the drug (lack of patient adherence to PPI therapy, inadequate dosage of PPI), residual acid reflux due to inadequate acid suppression, nocturnal acid escape, "non-acid" reflux, rapid metabolism of PPI, slow gastric emptying, and misdiagnosis of GERD. This is a common cause of failure of the clinical treatment and, in this case, the problem is not the treatment but the diagnosis. Causes of misdiagnosis of GERD are functional heartburn, achalasia, megaesophagus, eosinophilic esophagitis, other types of esophagitis, and other causes. The diagnosis and treatment are specific to each of these causes of refractoriness to clinical therapy with PPI.

RESUMO CONTEXTO: A doença do refluxo gastroesofágico (DRGE) é a condição clínica que se desenvolve quando o refluxo do conteúdo gástrico provoca sintomas incômodos e/ou complicações. O relaxamento transitório do esfíncter inferior do esôfago é o principal mecanismo fisiopatológico da DRGE. Os sintomas e complicações podem estar relacionados ao refluxo do conteúdo gástrico para o esôfago, cavidade oral, laringe e/ou pulmão. Os sintomas e outras possíveis manifestações da DRGE são pirose, regurgitação, disfagia, dor torácica não-cardíaca, tosse crônica, laringite crônica, asma e erosões dentárias. O inibidor da bomba de prótons (IBP) é o medicamento de primeira escolha e o mais comumente utilizado para o tratamento da DRGE. A definição mais difundida de DRGE Refratária é a condição clínica que apresenta sintomas com resposta parcial ou ausente ao tratamento com IBP duas vezes ao dia. A persistência dos sintomas ocorre em 25% a 42% dos pacientes que utilizam IBP uma vez ao dia e em 10% a 20% dos que utilizam IBP duas vezes ao dia. OBJETIVO: O objetivo é apresentar uma revisão da literatura atual, salientando as causas, aspectos diagnósticos e abordagem terapêutica dos casos com sintomas suspeitos de refluxo e não responsivos ao IBP. CONCLUSÃO - Inicialmente, o manejo da refratariedade ao IBP consiste em corrigir a baixa aderência à terapia com IBP, ajustar a dosagem do IBP e reforçar as recomendações sobre modificação do estilo de vida, evitando alimentos e atividades que desencadeiem os sintomas. O IBP diminui o número de episódios de refluxo ácido, no entanto o número de refluxos "não-ácidos" aumenta e o paciente continua apresentando refluxo apesar do IBP. Desta forma, é possível reduzir consideravelmente a ocorrência de sintomas, especialmente aqueles dependentes da acidez do material refluído. A resposta à terapia com IBP pode ser avaliada através de parâmetros clínicos, endoscópicos e de monitorização do refluxo. Na persistência dos sintomas, outras causas de DRGE Refratária devem ser suspeitadas. Em seguida, deve ser iniciada a investigação diagnóstica, que é apoiada por parâmetros clínicos e exames complementares, como endoscopia digestiva alta, manometria esofágica e monitorização ambulatorial do refluxo (pHmetria esofágica ou impedancio-pHmetria esofágica). As causas de refratariedade à terapia com IBP podem ser devidas à DRGE Refratária verdadeira ou mesmo a outras doenças não relacionadas ao refluxo, que podem gerar sintomas semelhantes à DRGE. Existem várias causas de refratariedade ao IBP, como uso inadequado da droga (falta de aderência do paciente à terapia com IBP, dosagem inadequada de IBP), refluxo ácido residual devido à supressão ácida inadequada, escape ácido noturno, refluxo "não-ácido", metabolismo rápido do IBP, esvaziamento gástrico lento e diagnóstico equivocado de DRGE. Este representa uma causa frequente de insucesso do tratamento clínico e neste caso, o problema não é o tratamento, mas sim o diagnóstico. As causas de diagnóstico equivocado da DRGE são pirose funcional, acalásia, megaesôfago, esofagite eosinofílica, outros tipos de esofagite e outras causas. O diagnóstico e o tratamento são específicos para cada uma dessas causas de refratariedade ao tratamento clínico com IBP.

Eficacia del tratamiento con omeprazol y bicarbonato de sodio en la enfermedad por reflujo gastroesofágico: revisión sistemática / Efficacy of omeprazole/sodium bicarbonate treatment in gastroesophageal reflux disease: a systematic review

INTRODUCCIÓN: Los inhibidores de la bomba de protones son la terapia médica más efectiva para la enfermedad de reflujo gastroesofágico, pero su inicio de acción puede ser lento. OBJETIVO: Evaluar la literatura referida a la eficacia del omeprazol y bicarbonato de sodio en la enfermedad por reflujo gastroesofágico. MÉTODOS: Revisión sistemática de la literatura desde el año 2000. Se revisaron los manuscritos relativos a la efectividad del tratamiento de la enfermedad por reflujo gastroesofágico. Se extrajo la información relevante, la cual fue subsecuentemente analizada con estadística descriptiva. RESULTADOS: Se incluyó información de cuatro estudios. Dos estudios compararon la eficacia de omeprazol y bicarbonato de sodio versus omeprazol, y un estudio comparó la eficacia de la dosis diaria matutina con la nocturna. El otro estudio comparó omeprazol más bicarbonato de sodio y alginato versus omeprazol. No hubo diferencia entre omeprazol con bicarbonato de sodio y omeprazol. Sin embargo, hubo una tendencia hacia una respuesta más sostenida y una mayor proporción de alivio total sostenido por 30 minutos con omeprazol y bicarbonato de sodio. CONCLUSIÓN: La terapia con omeprazol y bicarbonato de sodio no es más efectiva que el omeprazol en el tratamiento de la enfermedad por reflujo gastroesofágico. Sin embargo, la información sugiere que puede tener una respuesta más sostenida y un alivio total de mayor duración.

BACKGROUND: Proton pump inhibitors are the most effective medical therapy for gastroesophageal reflux disease, but their onset of action may be slow. OBJECTIVES: To assess the available literature regarding the efficacy of omeprazole/sodium bicarbonate in gastroesophageal reflux patients. METHODS: A systematic review was conducted. A systematic literature search starting from 2000. Reviewed manuscripts concerning the effectiveness of omeprazole/sodium bicarbonate treatment in gastroesophageal reflux disease were reviewed and the data were extracted. Data were subsequently analyzed with descriptive statistics. RESULTS: This review included information of four studies. Two trials compared the efficacy of omeprazole/sodium bicarbonate versus omeprazole. One study compared the efficacy of once-daily morning or nighttime dosing. And another study compared omeprazole/sodium bicarbonate/alginate versus omeprazole. In total, there was no difference between omeprazole/sodium bicarbonate and omeprazole. However, there is a trend towards more sustained response and a greater proportion of patients with sustained total relief by 30 minutes with omeprazole/sodium bicarbonate. CONCLUSION: Omeprazole/sodium bicarbonate therapy is not more effective than omeprazole in the treatment of gastroesophageal reflux disease. However, data obtained suggest that it can have a more sustained response and sustained total relief.

Prescripción de los inhibidores de la bomba de protones en pacientes hospitalizados / Prescription of proton pump inhibitors in hospitalized patient

Desde el comienzo del uso de los inhibidores de la bomba de protones (IBP), la indicación de los mismos ha crecido exponencialmente. Aquí documentamos la prescripción exagerada en pacientes hospitalizados. Métodos: estudio observacional descriptivo para determinar la frecuencia del uso inadecuado de estos fármacos en servicios médicos y quirúrgicos del Hospital Universitario de Caracas. Resultados: Se evaluaron 500 pacientes hospitalizados. Se prescribió IBP en 367 (73,4%) ellos, pero sólo 47 (12,8%) tenían una indicación formal. El 87% no tenía indicación justificada según normas de los entes reguladores a nivel mundial. La prevención de úlcera péptica inducida por AINES en pacientes de riesgo correspondió a la principal indicación de IBP; sin embargo, la dosis prescrita en el 82% de los pacientes no era la correcta. Conclusión: hay una alta prevalencia de prescripción de IBP, acompañada de alta frecuencia de prescripción inadecuada. Se debe educar a consumidores y prescriptores que, al igual que todos los fármacos, también los IBP tienen efectos adversos e interacciones medicamentosas, por lo que sólo se deberían usar cuando sea estrictamente necesario, con una indicación clara, a la menor dosis y durante el menor tiempo posible(AU)

Since the introduction of Proton Pump Inhibitors (PPIs), the indication of these has grown exponentially, evidencing a high prevalence of overprescription in hospitalized patients Method: a descriptive and observational study was carried out in order to determine the frequency of inappropriate use of these drugs in medical and surgical services of the Hospital Universitario de Caracas, Venezuela. Results: 500 hospitalized patients admitted to medical and surgical services were evaluated. The PPI was prescribed in 367 (73.4%) of them and only 47 (12.8%) had a formal indication for it, while 87% were not indicated, according to regulators worldwide. The prevention of peptic ulcer induced by non-steroidal antiinflammatory drugs in patients at risk was the major indication; however, the prescribed dose in 82% of patients was incorrect. Conclusion: there is a high prevalence of prescribing proton pump inhibitors, evidencing a high frequency of inadequate prescription. Consumers and prescribers should be made aware that, as all drugs, also PPIs have adverse effects, drug interactions, and should be used only when strictly necessary at the lowest dose and for the shortest time possible.(AU)

Estudio Transversal: Prescripción, Consumo y Automedicación de Inhibidores de Bomba de Protones en Pacientes de Atención Primaria del Azuay, 2016 / Cross-Sectional Research: Prescription, Consumption and Self-Medication of Proton Pump Inhibitors in Primary Care Patients from Azuay, 2016

OBJETIVO: El objetivo del presente estudio fue determinar la frecuencia de prescripción, consumo y prevalencia de automedicación de los inhibidores de la bomba de protones en pacientes atendidos en los Centros de Salud de Ludo y Cuchil, pertenecientes al cantón Sigsig ­ Azuay ­ Ecuador, durante el año 2016. MÉTODO: Estudio descriptivo transversal realizado con todos los pacientes quienes a la fecha de la consulta médica se encontraban consumiendo o tuvieron prescripción de inhibidores de la bomba de protones (IBPs). Se estudiaron las características socio-demográficas de la población, fármaco utilizado, indicaciones para su prescripción, prevalencia de automedicación y su relación con el género, edad, escolaridad y auto identificación étnica. RESULTADOS: Se revisaron 4758 pacientes, 228 pacientes ingresaron al estudio (4.79 %). La edad media fue de 48 ±20 años, las mujeres representaron el 73.25 %. El Omeprazol fue utilizado en el 96 % de los casos. La prevención de lesiones por AINES fue la principal indicación para el uso del medicamento. La prevalencia de automedicación fue de 31.58 %, existiendo relación con la edad mayor a 60 años (RP: 4.13; IC-95 %: 2.68-6.38) y la escolaridad primaria o inferior (RP: 4.87; IC-95 %: 2.22-10.68). CONCLUSIÓN: La frecuencia de prescripción y consumo de inhibidores de la bomba de protones fue de alrededor del 5 % de los pacientes estudiados. El Omeprazol fue el IPB de uso más frecuente. Existe una relación de riesgo y asociación entre la edad superior a 60 años y el nivel de escolaridad (primario o inferior) con la frecuencia de automedicación.(au)

OBJECTIVE: To determine the frequency of prescription, consumption and prevalence of self-medication of proton pump inhibitors in patients who attended to Ludo and Cuchil Health Centers during 2016. METHOD: A cross-sectional descriptive study performed with all the patients who were consuming or had a proton pump inhibitors (PPIs) prescription at the time of the medical attention. Socio-demographic characteristics of the population, used drug, prescription indications, self-medication prevalence and its relation with gender, age, schooling and ethnic self-identification were studied. RESULTS: Were reviewed 4758 patients, and 228 patients entered in this study (4.79 %). Average age was 48 ±20 years, 73.25 % of patients were female. Omeprazole was used in 96 % of the cases. Prevention of NSAID lesions was the main indication to use the drug. Self-medication prevalence reached 31.58 % and had a relation with age over 60 years (PR: 4.13; 95 %-CI: 2.68-6.38) and primary or lower scholarship (RP: 4.87; 95 %-CI: 2.22-10.68). CONCLUSION: Frequency of prescription and consumption of PPIs was around 5 % of students patients. Omeprazole was the most used PPI. There is an association and a risk relation between self-medication frequency and age over 60 years and lower scholarship level.(au)

Efficacy of 7-Day and 14-Day Bismuth-Containing Quadruple Therapy and 7-Day and 14-Day Moxifloxacin-Based Triple Therapy as Second-Line Eradication for Helicobacter pylori Infection

BACKGROUND/AIMS: Bismuth-containing quadruple and moxifloxacin-based triple regimens are recommended as second-line therapy for Helicobacter pylori infection. The aim of this study was to compare the efficacy of each regimen. METHODS: From August 2004 to October 2012, a total of 949 patients (mean age, 54.32+/-12.08 years; male, 49.4%) who failed H. pylori eradication with a standard triple regimen were included. Patients treated with a bismuth-containing quadruple regimen for 7 and 14 days were designated as 7-BMT and 14-BMT, respectively, and those treated with a moxifloxacin-based triple regimen for 7 and 14 days were designated as 7-MA and 14-MA, respectively. H. pylori eradication was confirmed using the 13C-urea breath test, rapid urease test or histology. RESULTS: The eradication rates by 7-BMT, 14-BMT, 7-MA, and 14-MA were 66.4% (290/437), 71.1% (113/159), 53.1% (51/96), and 73.5% (189/257), respectively, by intention-to-treat analysis (ITT) and 76.5% (284/371), 83.8% (109/130), 55.6% (50/90), and 80.6% (187/232), respectively, by per-protocol analysis (PP). The eradication rates were higher in 14-BMT than 7-BMT by the ITT and PP analyses (p=0.277 and p=0.082, respectively). The 14-BMT and 14-MA treatments showed similar efficacies by ITT and PP (p=0.583 and p=0.443, respectively). CONCLUSIONS: The 7-BMT, 14-BMT, and 14-MA treatments showed similar and suboptimal efficacies. In both regimens, extending the duration of treatment may be reasonable considering the high level of antibiotic resistance in Korea.

Laryngopharyngeal Reflux and Proton Pump Inhibitors.

Laryngopharyngeal reflux (LPR) refers to the backflow of stomach contents into the throat that is into the hypopharynx.LPR is different from classical GERD. Although PPIs appear to be effective, higher doses for a longer duration are necessary as compared with esophageal GERD disease. In this study we focused on clinical characteristics and role of proton pump inhibitors in Laryngopharyngeal Reflux. Material and Methods: The prospective observational study was done in LPR patients in the Department of ENT and HNS of SKIMS Medical College and Government Medical College Srinagar for a period of 2 years from 2010 to 2012 .Sixty cases were enrolled in the study. LPR was diagnosed on the basis of RFS and RSI. Role of PPI was assessed by the changes of RSI and RFS with Proton pump inhibitors. Results: Total number of patients included in the study were 60, 42 (70%) cases were females, 18 (30%) were males. Frequent clearing of throat was the most common symptom. Mean RSI of all patients was 25.25 before treatment. Significant change in RSI occurred after first 10 weeks of therapy and no further significant change occurred in the next 10 weeks. Most common laryngeal finding was erythema/hyperaemia; Mean RFS of the patients was 13 before treatment with proton pump inhibitors. There was slight response after 10 weeks of therapy in physical findings and significant response after 20 weeks. Conclusion: LPR is a common condition presenting in ENT settings, the symptoms and signs may be complex. PPI are treatment of choice and should be continued for about 5 months because clinical symptoms take about two month to resolve while signs take about 5 months to resolve.

Evolución de la respuesta al tratamiento de primera línea de la infección por Helicobacter pylori en Uruguay / [Evolution of the response to the first-line therapy for Helicobacter pylori infection in Uruguay].

INTRODUCTION: The eradication rate of the Helicobacter pylori (H pylori) infection using standard triple therapy has dropped globally in recent years, primarily due to the occurrence of antibiotic resistance. METHODS: Several therapy regimens were assessed in 823 patients treated the first time for H pylori infection in Uruguay, during the 1997 to 2011 period, divided into five-year groups. All patients underwent 13C isotope-urea breath testing, between the 8th and 24th weeks after therapy. The standard triple plan (amoxicillin, clarithromycin and proton pump inhibitors) was the most commonly used (86.8

(548 patients). With the standard triple plan, the reported eradication rates were 75

for the first 5-year term and 70.1

for the second 5-year term. The difference between these two periods was not statistically significant (P = 0.201). However, in the last term the eradication rate further declined to 62.4

, with a statistically significant difference (P = 0.014). No significant correlations were found between the response to therapy in this population and either the use of alcohol and/or yerba mate or the smoking habits. CONCLUSIONS: In Uruguay, the eradication rate of H pylori infection has dropped in the last five years and is below the internationally accepted levels. This feature demands searching for more effective alternative therapies, adapting the management to the national reality based on local antibiotic resistance patterns and drug availability.

Um ensaio randomizado duplo-cego e controlado por placebo com probióticos em casos de supercrescimento bacteriano no intestino delgado em crianças tratadas com omeprazol / A double-blind placebo-controlled randomized trial on probiotics in small bowel bacterial overgrowth in children treated with omeprazole

OBJETIVO: Avaliar a incidência de SBID em crianças tratadas com omeprazol e testar se os probióticos influenciam essa incidência. MÉTODOS: Um ensaio duplo-cego controlado por placebo foi realizado em 70 crianças tratadas oralmente, durante 4 semanas, com 20 mg de omeprazol por dia. Desses, 36 indivíduos receberam diária e simultaneamente Lactobacillus rhamnosus R0011 (1,9 x 10(9) cfu) e Lactobacillus acidophillus R0052 (0,1 x 10(9) cfu) (grupo probiótico), enquanto 34 receberam placebo (grupo placebo). O diagnóstico de SBID teve como base o desenvolvimento de sintomas sugestivos em combinação com um teste respiratório com glicose positivo. RESULTADOS: Após um mês de tratamento com IBP, 30% (21/70) apresentaram um teste respiratório positivo sugerindo SBID; desses, 62% foram sintomáticos. Cinco crianças desenvolveram sintomas parecidos com os de SBID, mas apresentaram um teste respiratório negativo; 44 (63%) não apresentavam sintomas e tiveram teste respiratório negativo. Não houve diferença na incidência de testes respiratórios positivos no grupo probiótico em comparação ao grupo placebo (33% em comparação a 26,5%; p: 0,13). CONCLUSÕES: Como houve sintomas sugestivos de SBID em 26% das crianças tratadas com IBP e o teste respiratório com glicose deu resultados anormais em 72% delas, esse efeito colateral deve ser levado em consideração com mais frequência. O probiótico testado não reduziu o risco de desenvolver SBID.

OBJECTIVE:To evaluate the incidence of small bowel bacterial overgrowth (SBBO) in children treated with omeprazole, and to test whether probiotics influence the incidence. METHODS: A double-blinded, placebo-controlled trial was performed in 70 children treated orally during four weeks with 20 mg omeprazole per day. Lactobacillus rhamnosus R0011 (1.9 x 10(9) cfu) and Lactobacillus acidophillus R0052 (0.1 x 10(9) cfu) were simultaneously given daily to 36 subjects (probiotic group), while 34 subjects received placebo (placebo group). The diagnosis of SBBO was based on the development of suggestive symptoms, in combination with a positive glucose breath test. RESULTS: After one month of proton pump inhibitor (PPI) treatment, 30% (21/70) had a positive breath test suggesting SBBO; of these 62% were symptomatic. Five children developed SBBO-like symptoms, but had a negative breath test; and 44 (63%) were symptom free and had a negative breath test. There was no difference in the incidence of positive breath tests in the probiotic versus the placebo group (33% vs 26.5%; p = 0.13). CONCLUSIONS: Since symptoms suggesting SBBO developed in 26% of PPI-treated children, and since the glucose breath test was abnormal in 72% of these, this side-effect should be more frequently considered. The probiotic tested did not decrease the risk to develop SBBO.

Comparison of oral and intravenous proton pump inhibitor in patients with high risk bleeding peptic ulcers

To compare the efficacy of oral omeprazole vs intravenous omeprazole in decreasing risk of re-bleeding in peptic ulcer patients. This prospective, randomized, controlled clinical trial was conducted at Ghulam Mohammad Mahar Medical College Hospital, Sukkur, Pakistan from January 2010 to December 2011. One hindered and six patients with high risk peptic ulcer were randomized to receive either oral omeprazole [80mg BID for 3 days] or IV omeprazole [80mg bolus and 8mg/hour infusion for 3 days] followed by omeprazole [20mg each day for 30 days]. All patients underwent upper endoscopy and endoscopic therapy within 24 hours. Seventeen patients were excluded from the study. Forty four patients were randomly allocated into oral omeprazole group and 41 to IV omeprazole group. Both groups were similar for factors affecting the outcome. Bleeding reoccurred in five patients of oral omeprazole group and four patients in IV omeprazole group [11.4% vs 9.8%]. The mean hospital stay and blood transfusion were not different in both groups. Oral omeprazole and IV omeprazole had equal effects on prevention of re-bleeding after endoscopic therapy in patients with high risk bleeding peptic ulcers

Infección por Helicobacter pylori / Helicobacter pylori infection

La infección por H. pylori afecta aproximadamente al 50 por ciento de la población mundial. Presenta una baja frecuencia relativa (20-40 por ciento) en países desarrollados y una alta frecuencia (70-90 por ciento) en países en desarrollo. En Chile, su frecuencia se estima entre 73-78 por ciento. Su presencia se asocia invariablemente a una gastritis histológica de intensidad variable, generalmente asintomática. Menos del 10 por ciento desarrollará una úlcera péptica (UP) gástrica o duodenal y menos del 1 por ciento un cáncer gástrico (CG) adenocarcinoma o linfoma MALT. Se ha sugerido también, aunque débilmente, su asociación con patologías extra-digestivas (anemia ferropriva, púrpura trombocitopénico idiopático y rosácea, entre otras). Basados en varios consensos y guías internacionales podemos establecer que existen indicaciones establecidas de diagnóstico y tratamiento, y otras controvertidas. Las indicaciones establecidas son: 1) UP, gástrica o duodenal, activa o no, complicada o no, con o sin antiinflamatorios no esteroidales (AINE) intercurrentes; 2) linfoma MALT y 3) adenocarcinoma gástrico posterior a gastrectomía parcial o resección endoscópica. Un meta-análisis de estudios clínicos controlados realizados en países con alta incidencia de CG, concluye que la erradicación de H. pylori disminuye el riesgo de CG, incluso en pacientes con lesiones pre-neoplásicas (atrofia gástrica y/o metaplasia intestinal) establecidas. La terapia de primera línea más recomendada es la triple terapia basada en inhibidores de bomba de protones con amoxicilina/metronidazol y claritromicina por 7-14 días. Las terapias de segunda línea consisten en: 1) terapia estándar triple no usada previamente; 2) terapia secuencial; 3) terapia cuádruple basada en bismuto; 4) terapia triple basada en levofloxacino o furazolidona.

Helicobacter pylori infection Infection with H. pylori affects around 50 percent of the world population. It has a low relative frequency (20 40 percent) in developed countries and a high frequency (70-90 percent) in developing countries. Chile has an estimated frequency of 73-78 percent. Its presence is invariably associated with histologic gastritis of varying severity, usually asymptomatic. Less than 10 percent will develop a peptic ulcer (PU), gastric or duodenal and less than 1 percent of gastric cancer (GC) adenocarcinoma or MALT lymphoma. It is also suggested, although weakly supported, its association with extra-digestive diseases (iron deficiency anemia, idiopathic thrombocytopenic purpura and rosacea, etc.). Based on several international consensus and guidance we can determine that there are established indications for diagnosis and treatment, and others that are controversial. The established indications are 1) PU, gastric or duodenal, active or not, complicated or not, with or without intercurrent use of NSAIDs 2) MALT lymphoma and 3) gastric adenocarcinoma after endoscopic resection or partial gastrectomy. A meta-analysis of controlled clinical trials developed in countries with high incidence of CG, concluded that eradication of H. pylori reduces the risk of CG, even in patients with pre-neoplastic lesions (gastric atrophy or intestinal metaplasia) established. The first-line therapy most recommended is triple therapy based on proton pump inhibitors with amoxicillin/metronidazole and clarithromycin for 7-14 days. The second-line therapies include: 1) standard triple therapy not previously used, 2) sequential therapy 3) bismuth-based quadruple therapy, 4) levofloxacin or furazolidone based triple therapy.
