Resumen La enfermedad de Whipple es una enfermedad multisistémica crónica, causada por la bacteria Tropherima whipplei. Se han descripto aproximadamente 1200 casos en la literatura. La incidencia mundial se estima en 9.8 casos por millón de personas. Los datos provenientes de Sudamérica y Europa muestran que afecta a varones de mediana edad. Se cree que los factores inmunológicos del huésped son los que influyen en el curso de la infección y no el genotipo del agente. Dado que las características clínicas no suelen ser específicas y el espectro de manifestaciones en órganos individuales puede ser subestimado, el diagnóstico sigue siendo muy difícil. Presentamos un caso confirmado por histopatología con compromiso multisistémico. Consideramos importante su difusión dados los escasos casos documentados en Sudamérica y la relevancia de tener presente la sospecha diagnóstica para el abordaje terapéutico precoz que mejora el pronóstico de esta rara enfermedad.
Abstract Whipple's disease is a chronic mutisystem disease caused by the bacteria Tropherima whipplei. Approximately 1200 cases have been described in the literature. The worldwide incidence is estimated at 9.8 cases per million people. Data from South America and Europe show that it affects middle-aged males. It is believed that host immunological factors rather than agent genotypic traits influence the course of the infection. Since the clinical characteristics are usually nonspecific and the wide spectrum of manifestations in individual organs may be underestimated, the diagnosis remains challenging. We present a case with multisystem compromise confirmed by histopathology. We consider its publication important given the few cases documented in South America and the relevance of bearing in mind the importance of an early diagnosis for a prompt treatment that improves the prognosis of this rare disease.

Resumen La resección transmural endoscópica es una técnica que permite la resección en bloque de lesiones colónicas en pacientes en los cuales han fracasado los métodos endoscópicos convencionales como la resección mucosa endoscópica o la disección submucosa endoscópica. Presentamos el caso de un hombre de 75 años con antecedentes de adenoma de colon con fibrosis debido a dos intentos previos fallidos de resección endoscópica en otra institución. Realizamos con éxito el procedimiento de resección transmural endoscópica evitando así una cirugía.
Abstract Endoscopic full-thickness resection is a technique that allows in block resection of colonic lesions in patients in whom conventional endoscopic methods such as endoscopic mucosal resection or endoscopic submucosal dissection have failed. We present a case of a 75-year-old man with history of a difficult-to-resect colon adenoma. He had undergone two previous failed attempts of endoscopic mucosal resection due to non-lifting sign in another center. We successfully performed an endoscopic full-thickness resection procedure, avoiding unnecessary surgery.

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.

RESUMEN La colangiopancreatografía retrógrada endoscópica (CPRE) representa el tratamiento de primera línea para el drenaje biliar en pacientes con obstrucción biliar maligna avanzada. Sin embargo, este procedimiento representa un desafío en pacientes con anatomía alterada quirúrgicamente. El ultrasonido endoscópico (USE) permite la toma de muestras de tejido mediante punción aspiración con aguja fina y también representa una alternativa de drenaje biliar al abordaje percutáneo o quirúrgico. Nuestro objetivo es comunicar un caso en el que la ecoendoscopia permitió el diagnóstico definitivo de la recurrencia de la enfermedad oncológica de base y el alivio de la obstrucción biliar en un paciente con anatomía alterada quirúrgicamente.
ABSTRACT Endoscopic retrograde cholangiography with biliary stenting is the generally recognized optimal treatment of malignant biliary obstruction. This procedure, though, is challenging in patients with surgically altered anatomy. Endoscopic ultrasound (EUS) enables tissue sampling by means of fine-needle aspiration and also represents an alternative recourse for biliary drainage in preference to a percutaneous approach. We aimed to report a case in which EUS enabled a definitive diagnosis of the recurrence of oncologic disease and the relief of biliary obstruction in a patient with a surgically altered anatomy.

ABSTRACT Inflammatory bowel disease comprises two distinct conditions - Crohn's disease and ulcerative colitis - which can be treated with immunomodulators. A non-neglectable proportion of these patients will need biologic therapy, and many patients under biologic treatment will experience either primary or secondary failure. As a consequence, clinical trials evaluating new therapeutic alternatives are being developed. These trials share common features, such as being controlled with placebo. Placebo use in clinical trials is a matter of intense debate. Those who support placebo use highlight the methodologic advantages placebo-controlled trials have. Those against placebo use argue that it would be against ethical principles in clinical research to expose a patient to placebo when a valid therapeutic alternative exists. In this review, we summarize the existing arguments for and against the use of placebo in the context of inflammatory bowel disease research. We finally suggest that it is very likely that in the near future inflammatory bowel disease trials will no longer be controlled with a placebo arm, but instead they will be non-inferiority trials with an active comparator.
RESUMO A doença inflamatória intestinal compreende duas condições distintas: a doença de Crohn e a retocolite ulcerativa, que podem ser tratadas com imunomoduladores. Uma proporção não negligenciável desses pacientes necessitará de terapia biológica e, muitos destes em tratamento biológico, experimentarão falha primária ou secundária. Como consequência, ensaios clínicos avaliando novas alternativas terapêuticas estão sendo desenvolvidos. Estes ensaios partilham características comuns, tais como ser controlado com placebo. O uso de placebo em ensaios clínicos é uma questão de intenso debate. Aqueles que apoiam o uso do placebo destacam as vantagens metodológicas que os ensaios controlados com placebo têm. Aqueles contra o uso de placebo argumentam que seria contra os princípios éticos na investigação clínica expor um paciente ao placebo quando uma alternativa terapêutica válida existe. Nesta revisão, resumimos os argumentos existentes a favor e contra o uso de placebo no contexto da pesquisa de doença inflamatória intestinal. Finalmente, sugerimos que é muito provável que em um futuro próximo os ensaios de doença inflamatória intestinal não serão mais controlados com um braço placebo; em vez disso, serão feitos ensaios de não-inferioridade com um comparador ativo.

ABSTRACT BACKGROUND: Endoscopic mucosal resection is one of the most frequent therapeutic alternatives for large colorectal lateral spreading tumors. There are few data on the prevalence of synchronous lesions on these patients. OBJECTIVE: To describe the prevalence of synchronous colorectal lesions in patients referred for endoscopic mucosal resection of lateral spreading tumors >20 mm. METHODS: We reviewed the endoscopic database of our Department and identified adult patients who were referred for the resection of a colorectal lateral spreading tumor >20 mm and had a diagnostic colonoscopy performed up to six months before. The proportion of patients with at least one synchronous lesion was estimated. The following features were compared between patients with and without synchronous lesions: age, gender, bowel preparation quality and cecal intubation on index colonoscopy and therapeutic colonoscopy, serrated adenoma as index lesion. RESULTS: From December 2016 to November 2017, we identified 70 patients who fulfilled inclusion criteria. Median size of lesions was 25 mm (20-45). Eighty percent were located in the right colon and 35.71% were serrated adenomas. Synchronous lesion rate was 38.57%. Bowel preparation quality was similar in both groups when comparing both index and therapeutic colonoscopies. Patients with synchronous lesions had a higher proportion of serrated adenoma as index lesion than patients without synchronous lesions [51.85% vs 25.58%, OR 3.13 (1.13-8.68), P=0.03]. CONCLUSION: We found a high prevalence of synchronous lesions among patients with a large colorectal lateral spreading tumor. This risk seems to be increased if index lesions are serrated adenomas.
DESCRITORES CONTEXTO: A ressecção endoscópica de mucosa é uma das alternativas terapêuticas frequentes para grandes tumores colorretais de propagação lateral. Há poucos dados sobre a prevalência de lesões síncronas nesses pacientes. OBJETIVO: Descrever a prevalência de lesões colorretais síncronas em pacientes encaminhados para ressecção endoscópica da mucosa de tumores de disseminação lateral >20 mm. MÉTODOS: Realizou-se a revisão de banco de dados endoscópicos de nosso departamento e foram identificados pacientes adultos encaminhados para a ressecção de um tumor colorretal com propagação lateral >20 mm e que tiveram colonoscopia diagnóstica realizada até seis meses antes. Estimou-se a proporção de pacientes com pelo menos uma lesão síncrona. As seguintes características foram comparadas entre pacientes com e sem lesões síncronas: idade, sexo, qualidade da preparação intestinal e intubação cecal pelo índice de colonoscopia e adenoma serrilhado como lesão índice. RESULTADOS: De dezembro de 2016 a novembro de 2017, identificamos 70 pacientes que preencheram os critérios de inclusão. O tamanho mediano das lesões foi de 25 mm (20-45). Foram 80% situados no cólon direito e 35,71% eram adenomas serrilhados. A taxa de lesão síncrona foi de 38,57%. A qualidade da preparação intestinal foi semelhante em ambos os grupos comparando-se os índices e colonoscopia terapêutica. Pacientes com lesões síncronas apresentaram maior proporção de adenoma serrilhado como lesão índice do que pacientes sem lesões síncronas [51,85% vs 25,58%, or 3,13 (1,13-8,68), P=0,03]. CONCLUSÃO: Encontramos alta prevalência de lesões síncronas entre pacientes com grande tumor de propagação lateral colorretal. Este risco parece ser aumentado se as lesões índice forem adenomas serrilhados.

La diarrea por Clostridium difficile es reconocida de manera creciente en pacientes hospitalizados y se asocia con alta mortalidad. La vancomicina por vía enteral es el tratamiento antibiótico recomendado para las diferentes formas, incluso las más graves. Sin embargo, un grupo pequeño de pacientes desarrolla formas refractarias a ese tratamiento y no existen esquemas antibióticos alternativos recomendados para estos casos. El trasplante de microbiota fecal ha demostrado ser exitoso en una serie de casos de diarrea grave asociada a este microorganismo. Presentamos un caso de diarrea refractaria por C. difficile que fue tratada con éxito con una infusión de microbiota fecal.
Clostridium difficile infection is an increasingly recognized cause of diarrhea in inpatients, frequently associated to high mortality. Vancomycin is the treatment of choice for all Clostridium difficile- associated diarrheas, with different degrees of severity. However, some patients develop refractory forms to that treatment and there are no alternative antibiotic schemes recommended for these cases. Fecal microbiota transplantation has been shown to be successful in a series of cases of severe diarrhea associated with this organism. We present a case of refractory C. difficile infection successfully treated with fecal microbiota transplantation.

ABSTRACT BACKGROUND: Intestinal secretagogues have been tested for the treatment of chronic constipation and constipation-predominant irritable bowel syndrome. The class-effect of these type of drugs has not been studied. OBJECTIVE: To determine the efficacy and safety of intestinal secretagogues for the treatment of chronic constipation and constipation-predominant irritable bowel syndrome. METHODS: A computer-based search of papers from 1966 to September 2017 was performed. Search strategy consisted of the following MESH terms: intestinal secretagogues OR linaclotide OR lubiprostone OR plecanatide OR tenapanor OR chloride channel AND chronic constipation OR irritable bowel syndrome. Data were extracted as intention-to-treat analyses. A random-effects model was used to give a more conservative estimate of the effect of individual therapies, allowing for any heterogeneity among studies. Outcome measures were described as Relative Risk of achieving an improvement in the symptom under consideration. RESULTS: Database Search yielded 520 bibliographic citations: 16 trials were included for analysis, which enrolled 7658 patients. Twelve trials assessed the efficacy of intestinal secretagogues for chronic constipation. These were better than placebo at achieving an increase in the number of complete spontaneous bowel movements per week [RR 1.87 (1.24-2.83)], at achieving three or more spontaneous bowel movements per week [RR 1.56 (1.31-1.85)] and at inducing spontaneous bowel movement after medication intake [RR 1.49 (1.07-2.06)]. Similar results were observed when assessing the efficacy of intestinal secretagogues on constipation-predominant irritable bowel syndrome based on the results of six trials. CONCLUSION: Intestinal secretagogues are useful and safe therapeutic alternatives for the treatment of constipation-related syndromes.
RESUMO CONTEXTO: Os secretagogos intestinais têm sido testados para o tratamento da constipação crônica e síndrome do intestino irritável com constipação predominante. O efeito classe desses tipos de drogas ainda não foi estudado. OBJETIVO: Determinar a eficácia e a segurança de secretagogos intestinais para o tratamento da constipação crônica e síndrome do intestino irritável de constipação predominante. MÉTODOS: Realizada pesquisa baseada em banco de dados de trabalhos publicados entre 1966 e setembro de 2017. A estratégia de pesquisa consistia dos seguintes termos MeSH: secretagogos intestinais OU linaclotide OU lubiprostona OU plecanatide OU tenapanor OU canal de cloro E constipação crônica OU síndrome do intestino irritável. Os dados foram extraídos como análises de intenção de tratar. Um modelo de efeitos aleatórios foi usado para dar uma estimativa mais conservadora do efeito das terapias individuais, permitindo a qualquer heterogeneidade entre os estudos. Os desfechos foram descritos como risco relativo de alcançar uma melhoria no sintoma em consideração. RESULTADOS: A busca no banco de dados rendeu 520 citações bibliográficas: 16 ensaios foram incluídos para análise, que incluiu 7658 pacientes. Doze trabalhos avaliaram a eficácia de secretagogos intestinais para constipação crônica. Estes foram melhores do que placebo, alcançando um aumento no número de evacuações completas espontâneas por semana [RR 1,87 (1,24-2,83)], para a aquisição de três ou mais evacuações espontâneas por semana [RR 1,56 (1,31-1,85)] e na indução espontânea do movimento intestinal após a ingestão de medicação [RR 1,49 (1,07-2,06)]. Resultados semelhantes foram observados ao avaliar a eficácia de secretagogos intestinais na síndrome do intestino irritável de constipação predominante com base em resultados de seis ensaios. CONCLUSÃO: Os secretagogos intestinais são alternativas terapêuticas úteis e seguras para o tratamento de síndromes relacionadas à constipação.

ABSTRACT BACKGROUND: An association has been established between low serum values of vitamin D and inflammatory bowel disease. There is a lack of evidence on whether this association is still observed in regions where sun exposure throughout the year is higher. OBJECTIVE: To compare the prevalence of vitamin D deficiency between inflammatory bowel disease patients and healthy controls. METHODS: Inflammatory bowel disease patients were consecutively enrolled as cases. Age and gender-matched healthy subjects who agreed to undertake a determination of serum vitamin D were enrolled as controls. Demographic features, medical treatment, need for hospital admission at diagnosis, steroid treatment, smoking, need for surgical treatment were evaluated as factors associated with vitamin D deficiency. RESULTS: Overall, 59 patients with a diagnosis of either Crohn's disease or ulcerative colitis were enrolled, as well as 56 controls. Median age was 41 years (19-79) and 56% were male. Vitamin D deficiency was observed in 66.1% of inflammatory bowel disease patients versus 21.42% of healthy controls (OR 7.15 (3.1-16.48), P=0.001). Among inflammatory bowel disease patients, male gender, disease duration, moderate-to-severe disease and hospital admission at the moment of diagnosis were found to be associated with vitamin D deficiency. On multivariate analysis, only longer disease duration [(OR 1.01 (1-1.06)] and hospital admission at diagnosis [(OR 5.63 (1.01-31.61)] were found to be significantly associated with the latter. CONCLUSION: Vitamin D deficiency was more frequent among inflammatory bowel disease patients. Longer disease duration and need for hospital admission at diagnosis were associated to vitamin D deficiency among these patients.
RESUMO CONTEXTO: Uma associação foi estabelecida entre os baixos valores séricos de vitamina D e doença inflamatória intestinal. Falta evidência se esta associação ainda é observada em regiões onde a exposição ao sol durante todo o ano é maior. OBJETIVO: Comparar a prevalência de deficiência de vitamina D entre pacientes com doença inflamatória intestinal e indivíduos controles saudáveis. MÉTODOS: Pacientes com doença inflamatória intestinal foram consecutivamente selecionados. Indivíduos saudáveis combinados da mesma idade e gênero que concordaram em fornecer uma determinação da vitamina D do soro foram considerados como controles. Características demográficas, tratamento médico, necessidade de admissão hospitalar no diagnóstico, tratamento de esteroides, tabagismo, necessidade de tratamento cirúrgico foram avaliados como fatores associados à deficiência de vitamina D. RESULTADOS: No geral, 59 pacientes com diagnóstico de doença de Crohn ou colite ulcerosa foram observados, bem como 56 controles. A idade mediana era de 41 anos (19-79) e 56% eram do sexo masculino. A deficiência de vitamina D foi observada em 66,1% dos pacientes com doença inflamatória intestinal versus 21,42% dos controles saudáveis (OR 7,15 (3.1-16.48), P=0,001). Entre os pacientes com doença inflamatória intestinal, sexo masculino, duração da doença, doença de moderada a severa e admissão hospitalar no momento do diagnóstico foram associados com a deficiência de vitamina D. Na análise multivariada, apenas a duração da doença [(OR 1; 1 (1-1,06)] e a admissão hospitalar no diagnóstico [(OR 5,63 (1,01-31,61)] foram encontradas significativamente associadas ao último. CONCLUSÃO: A deficiência de vitamina D foi mais frequente entre os pacientes com doença inflamatória intestinal. Maior duração da doença e necessidade de admissão hospitalar no diagnóstico foram associadas à deficiência de vitamina D entre esses pacientes.

Background Some previously published studies have suggested an inverse relationship between celiac disease and Helicobacter pylori, raising the possibility of the protective role Helicobacter pylori could have against celiac disease development. Nevertheless, this association is inconclusive. Objectives To determine the prevalence of Helicobacter pylori infection in celiac subjects. Methods Between January 2013 and June 2014, patients over 18 years old undergoing upper endoscopy who required both gastric and duodenal biopsies were included for analysis. Enrolled subjects were divided in two groups: those with a diagnosis of celiac disease and those without a celiac disease diagnosis. Helicobacter pylori infection prevalence was compared between groups. Among celiac patients, endoscopic markers of villous atrophy as well as histological damage severity were compared between those with and without Helicobacter pylori infection. Results Overall, 312 patients were enrolled. Seventy two of them had a diagnosis of celiac disease. Helicobacter pylori infection prevalence among celiac disease patients was 12.5%, compared to 30% in non-celiac patients [OR=0.33 (0.15-0.71)]. There was not a significant difference in terms of the severity of villous atrophy in patients with Helicobacter pylori infection compared to those without it. There was a slight increase in the prevalence of endoscopic markers in those Helicobacter pylori-negative celiac subjects. Conclusion Helicobacter pylori infection seems to be less frequent in celiac patients; among those celiac subjects with concomitant Helicobacter pylori infection, histological damage degree and presence of endoscopic markers suggesting villous atrophy seem to be similar to those without Helicobacter pylori infection. .
Contexto Alguns estudos publicados anteriormente sugerem uma relação inversa entre a doença celíaca e Helicobacter pylori, levantando a possibilidade do papel protetor que o Helicobacter pylori poderia ter contra o desenvolvimento de doença celíaca. No entanto, esta associação é inconclusiva. Objetivos Determinar a prevalência da infecção por Helicobacter pylori em indivíduos celíacos. Métodos Entre janeiro de 2013 e de 2014 junho, foram incluídos para análise pacientes com mais de 18 anos de idade submetidos a endoscopia para necessárias biópsias gástricas e duodenais. Os pacientes foram divididos em dois grupos: aqueles com diagnóstico de doença celíaca e aqueles sem um diagnóstico de doença celíaca. A prevalência da infecção por Helicobacter pylori foi comparada entre os grupos. Entre os pacientes celíacos, os marcadores endoscópicos de atrofia das vilosidades, bem como a gravidade do dano histológico foram comparados entre aqueles com e sem infecção pelo Helicobacter pylori. Resultados De um total de 312 pacientes, 72 deles tiveram diagnóstico da doença celíaca. A prevalência de infecção pelo Helicobacter pylori entre pacientes com doença celíaca foi de 12,5%, em comparação com 30% em pacientes não-celíacos [OR=0,33 (0,15-0,71)]. Não houve diferença significativa em termos da gravidade da atrofia das vilosidades em pacientes com infecção pelo Helicobacter pylori em comparação com aqueles sem ele. Houve um ligeiro aumento na prevalência de marcadores endoscópicos nos indivíduos celíacos com Helicobacter pylori-negativo. Conclusão A infecção pelo Helicobacter pylori parece ser menos frequente em pacientes celíacos; entre esses indivíduos celíacos com concomitante infecção por Helicobacter pylori, o grau de dano histológico e a presença de marcadores endoscópicos sugerindo atrofia vilosa, parecem ser semelhantes com os sem infecção. .

Context Celiac disease is an autoimmune disorder of the small intestine associated with several extra-intestinal features, such as reproductive disorders. The relationship between celiac disease and infertility has been previously assessed, with conflicting results. Objectives We seek to determine the relationship between celiac disease and infertility. Methods Data was extracted from case-control or cohort design studies from 1966 to December 2013 using the MEDLINE-Pubmed, EMBASE, LILACS and Cochrane Library databases. We analyzed two kinds of trials: those assessing the risk of infertility in subjects with already diagnosed celiac disease, and those evaluating the prevalence of undiagnosed celiac disease in subjects with a diagnosis of infertility. Results The search yielded 413 potentially relevant studies for revision, 12 of which were finally included for analysis. A significant association was found between women with a diagnosis of infertility and undiagnosed celiac disease [OR 3.09 (95% CI 1.74-5.49)]. When considering those studies assessing the occurrence of infertility in subjects with already-diagnosed celiac disease, no difference was found between celiac disease patients and control subjects [OR 0.99 (0.86-1.13)]. Conclusions Undiagnosed celiac disease is a risk factor for infertility. Women seeking medical advice for this particular condition should be screened for celiac disease. Adoption of a gluten-free diet could have a positive impact on fertility in this group of patients. .
Contexto A doença celíaca é uma doença auto imune do intestino delgado associada a manifestações extra-intestinais, tais como distúrbios reprodutivos. A relação entre a doença celíaca e a infertilidade foi previamente avaliada, com resultados conflitantes. Objetivos Procuramos determinar a relação entre a doença celíaca e a infertilidade. Métodos Utilizou-se dados extraídos de estudos de projeto de caso-controle ou coorte de 1966 à dezembro de 2013 utilizando o MEDLINE-Pubmed, EMBASE, LILACS e Cochrane Library. Foram analisados dois tipos de ensaios: os que avaliam o risco de infertilidade em pacientes com doença celíaca já diagnosticados e, os que avaliam a prevalência da doença celíaca não diagnosticada em indivíduos com diagnóstico de infertilidade. Resultados A busca resultou em 413 estudos potencialmente relevantes para a revisão, 12 dos quais foram finalmente incluídos para análise. Foi encontrada uma associação significativa entre as mulheres com diagnóstico de infertilidade e doença celíaca não diagnosticada [TR 3,09 (IC 95% 1,74-5,49)]. Ao considerar esses estudos avaliando a ocorrência de infertilidade em pacientes com doença celíaca já diagnosticada, não foi encontrada diferença entre os pacientes com doença celíaca e controles [TR 0,99 (0,86-1,13)]. Conclusões A falta de diagnóstico para a doença celíaca é um fator de risco para a infertilidade. As mulheres que procuram o conselho médico para esta condição particular, devem ser examinados para a doença celíaca. A adoção de uma dieta sem glúten pode ter um impacto positivo sobre a fertilidade neste grupo de pacientes. .

La pancreatitis aguda (PA) es una patología con múltiples etiologías y de curso clínico diverso. En nuestro medio son escasas las comunicaciones acerca de esta entidad y en general abordan temas puntuales dentro del amplio espectro del cuadro. El objetivo de este trabajo es determinar las características clínicas, la etiología, el manejo y la evolución de los pacientes internados en nuestra institución con diagnóstico de PA. Se analizaron retrospectivamente los registros clínicos de los pacientes con diagnóstico de PA entre abril de 2004 y abril de 2007. Se evaluaron los datos poblacionales, etiología, tratamiento instaurado, gravedad y morbimortalidad. En el período analizado, 97 pacientes fueron internados con diagnóstico de PA. Cuarenta y nueve fueron de sexo masculino (50.5%). La edad promedio fue de 58.5 ± 1.6 años (rango 21-93). Noventa y dos pacientes presentaron un solo episodio de PA, y 5 pacientes dos o más episodios (pancreatitis recurrente). Según su etiología, 48 fueron de origen biliar, 23 idiopáticas, 11 post-procedimientos en la vía biliar, 2 de origen alcohólico y 13 de otras causas. La mediana de estadía hospitalaria fue 7 días. El 25% requirió internación en Unidad de Terapia Intensiva. Según la escala de Ranson la mayoría de los pacientes (n: 66; 72%) presentaron cuadros leves. La mediana de inicio de alimentación oral fue de 3 días. Con respecto a las complicaciones, 13% presentaron falla multiorgánica, 8% necrosis pancreática (4 infectadas), sólo un paciente desarrolló un seudoquiste y otro un absceso pancreático. La mortalidad fue 7.2% (7 casos, todos con Ranson ≥ 3). La PA de origen biliar resultó ser la más común y si bien la presente es una serie pequeña, llama la atención el bajo número de PA de origen alcohólico. Aunque el número de complicaciones locales fue menor, la mortalidad fue similar a la descripta en la literatura. Nuestros datos también son coincidentes en cuanto al manejo y pronóstico de la PA. El presente trabajo actualiza la casuística en Argentina.
Acute pancreatitis (AP) is a disease with several causes and diverse clinical course. In our environment there are not many papers on this entity and they approach punctual features inside the broad spectrum picture. The aim of this study is to determinate clinical features, etiology, handling and evolution of patients diagnosed with AP admitted in our Hospital during a three years period. The clinical records of patients with AP admitted at the British Hospital of Buenos Aires between April 2004 and April 2007 were retrospectively analyzed. Demographic data, etiology, treatment, severity of the illness, morbidity and mortality were evaluated. Ninety seven patients were diagnosed with AP during the analyzed period. Forty nine were male (50.5%). The average age was 58.5 ± 1.6 years (range 21-93). Ninety two patients presented only one episode of AP and five patients suffered two or more (recurrent pancreatitis). According to the etiology, 48 had a biliary origin, 23 were idiopathic, 11 post biliary tract procedures, 2 recognized an alcoholic origin and 13 other causes. The median hospital stay was 7 days. Twenty five percent required admission in Intensive Care Unit. Most of the patients (n: 66; 72%) presented mild episodes according to the Ranson Score.
