Síndrome urémico hemolítico: reporte de dos casos pediátricos con nexo epidemiológico / Hemolytic uremic syndrome: report of two pediatric clinical cases with epidemiologic link / Síndrome urémico hemolítico: reporte de casos pediátricos con nexo epidemiológico

Introducción: el síndrome hemolítico urémico (SHU) es en muchos países, de las causas más frecuentes de insuficiencia renal aguda. La mayoría de los casos ocurre luego de un episodio de gastroenteritis aguda (GEA) por Escherichia coli productora de toxina Shiga (STEC). En Uruguay a pesar de ser una enfermedad de notificación obligatoria, existe subregistro. Objetivo: describir dos casos clínicos de SHU asociados a GEA con nexo epidemiológico. Casos clínicos: se trata de dos varones de 4 y 5 años, sanos. En los días previos, ingesta de carne en el mismo local comercial. Consultaron por dolor abdominal, deposiciones líquidas y vómitos reiterados. El niño de 4 años presentaba fiebre y deposiciones líquidas con sangre. El niño de 5 años dolor abdominal. El estado de hidratación y las constantes vitales eran normales en ambos. Fueron admitidos a cuidados moderados. A las 48 horas y a los 5 días, respectivamente, agregan palidez cutáneo-mucosa intensa, edemas y oliguria. Estudios complementarios: anemia, plaquetopenia e insuficiencia renal. Ingresaron a cuidados intensivos y se realizó diálisis peritoneal. La investigación de STEC fue negativa y la evolución favorable. Conclusiones: en menores de 5 años el SHU asociado a GEA es la forma de enfermedad más frecuente. En Uruguay predominan las cepas STEC no-O157. En estos casos no se pudo identificar el agente. La existencia de un nexo epidemiológico alerta sobre la necesidad de extremar los cuidados en la preparación y cocción de la carne. Debido a la asociación con una enfermedad prevalente, es necesario tener presente esta complicación para poder sospecharla e iniciar el tratamiento en forma precoz y oportuna.

Introduction: hemolytic uremic syndrome (HUS) is one of the most frequent causes of acute renal failure in many countries. Most cases occur after an episode of acute gastroenteritis (GEA) due to the Shiga toxin producing Escherichia Soli (STEC). In Uruguay, despite being a disease that requires mandatory notification, it is under reported. Objective: to describe two clinical cases of HUS associated with GEA with an epidemiological link. Clinical cases: these are two healthy boys aged 4 and 5 years. In the previous days, they reported meat intake in the same commercial premises. They consulted for abdominal pain, liquid stools and repeated vomiting. The 4 year old boy had a fever and bloody stools. The 5 year old boy had abdominal pain. They both showed normal hydration levels and vital signs. They were admitted to moderate care. At 48 hours and 5 days, respectively, they showed intense skin and mucosal paleness, edema and oliguria. Complementary studies: anemia, thrombocytopenia and renal failure. They were admitted to intensive care and peritoneal dialysis was performed. The STEC's investigation was negative and the evolution favorable. Conclusions: in children under 5 years of age, HUS associated with GEA is the most frequent form of the disease. In Uruguay, non-O157 STEC strains predominate. In these cases, the agent could not be identified. The existence of an epidemiological link warns us about the need for extreme care in the preparation and cooking of meat. Due to the association with a prevalent disease, it is necessary to keep this complication in mind in order to suspect it and initiate early and timely treatment.

Introdução: a síndrome hemolítico urêmica (SHU) é uma das causas mais frequentes de insuficiência renal aguda em muitos países. A maioria dos casos ocorre após um episódio de gastroenterite aguda (GEA) devido à Escherichia Coli, a toxina produtora de Shiga (STEC). No Uruguai, apesar de ser uma doença de notificação compulsória, há subnotificação. Objetivo: descrever dois casos clínicos de SHU associada à AGE com vínculo epidemiológico. Casos clínicos: dois meninos saudáveis com idades entre 4 e 5 anos. Nos dias anteriores, eles reportaram consumo de carne nos mesmos estabe- lecimentos comerciais. Eles consultaram para dor abdominal, fezes líquidas e vômitos repetidos. O menino de 4 anos teve febre e fezes com sangue. O menino de 5 anos teve dores abdominais. O estado de hidratação e os sinais vitais foram normais em ambos meninos. Foram internados em cuidados moderados. Às 48 horas e 5 dias, respectivamente, apresentaram aliás palidez intensa da pele e mucosas, edema e oligúria. Realizaramse estudos complementares: anemia, trombocitopenia e insuficiência renal. Eles foram internados em terapia intensiva e realizouse diálise peritoneal. A investigação do STEC foi negativa e a evolução favorável. Conclusões: em crianças menores de 5 anos, a SHU associada à GEA é a forma mais frequente da doença. No Uruguai, predominam cepas STEC não-O157. Nesses casos, o agente não pôde ser identificado. A existência de um nexo epidemiológico alerta para a necessidade de extremo cuidado no preparo e cozimento da carne. Devido à associação com doença prevalente, é necessário considerar essa complicação para suspeitar e iniciar o tratamento precoce e oportunamente.

Patologías funcionales post-infecciosas: epidemiología, factores de riesgo y tratamiento / Post-infectious functional gastrointestinal disorders: epidemiology, risk factors and treatment

Infectious gastroenteritis is a risk factor for developing post-infectious functional gastrointestinal disorders (PI-FGDs), mainly irritable bowel syndrome (IBS) and functional dyspepsia (FD). It is a significant subgroup of patients due to frequent episodes of gastrointestinal infections. Symptoms in PI-FGD patients can prevail for more than twelve months, especially if infective agents are bacteria or parasites. Symptoms are indistinguishable from their non-infective equivalents (IBS and FD). Risk factors for developing PI-FGD are: female gender, type and severity of the gastrointestinal infection, high anxiety levels and younger age. Main pathogenic mechanisms are alteration of permeability and immunity. Mucosa inflammation prevails only at early stage; however, with follow-up it can be reduced or normalized. Nevertheless, certain alterations prevail, such as hypersensitivity. These events are treated in the same way as IBS or FD.

La gastroenteritis infecciosa es un factor de riesgo para desarrollar un trastorno digestivo funcional postinfeccioso (TDF-PI), principalmente síndrome de intestino irritable (SII) y dispepsia funcional (DF). Es un subgrupo de pacientes relevante debido a lo frecuente que son las infecciones gastrointestinales. Los síntomas en los pacientes con TDF-PI se pueden prolongar por más de un año, especialmente cuando los agentes infecciosos son bacterias o parásitos. Los síntomas son indistinguibles con respecto a los de sus equivalentes no infecciosos (SII y DF). Los factores de riesgo para desarrollar TDF-PI son el sexo femenino, el tipo y la severidad de la infección gastrointestinal, los niveles altos de ansiedad, y la menor edad. Los principales mecanismos patogénicos son la alteración de la permeabilidad y de inmunidad. La inflamación de la mucosa predomina solo al principio pero con el seguimiento esta disminuye o se normaliza, a pesar de lo cual ciertas alteraciones como la hiperensibilidad permanecen. Estos cuadros se tratan de la misma manera que un SII o DF.

Identification of Human Bocavirus type 4 in a child asymptomatic for respiratory tract infection and acute gastroenteritis - Goiânia, Goiás, Brazil

Abstract Human Bocavirus (HBoV) has been identified from feces and respiratory samples from cases of both acute gastroenteritis and respiratory illness as well as in asymptomatic individuals. The aim of this study was to detect and characterize HBoV from fecal samples collected from hospitalized children aged less than five years old with no symptoms of respiratory tract infection (RTI) or acute gastroenteritis (AGE). The study involved 119 children and one fecal sample was collected from each participant between 2014 and 2015. HBoV was detected using Nested-PCR, and the viral type identified by genomic sequencing. HBoV-4 was identified from one sample obtained from a hospitalized child with soft tissue tumor of the submandibular region. This is the first report of HBoV-4 identification in Brazil, but we consider that this type may be circulating in the country similar to the other types and new investigations are necessary.

Semiquantitative fecal calprotectin test in postinfectious and non-postinfectious irritable bowel syndrome: cross-sectional study / Teste calprotectina fecal semiquantitativa na síndrome do intestino irritável pós-infecciosa e não pós-infecciosa: estudo transversal

CONTEXT AND OBJECTIVE:The presence of a certain degree of inflammation in the gut wall is now accepted in irritable bowel syndrome (IBS). Fecal calprotectin is considered to be a reliable test for detecting intestinal inflammation. Our aim was to assess the presence of inflammation in postinfectious IBS (PI-IBS), compared with non-postinfectious IBS (NPI-IBS). A secondary objective was to determine the usefulness of a rapid fecal calprotectin test in inflammatory bowel diseases (IBD).DESIGN AND SETTING:This was a cross-sectional study. Patients with IBS and IBD at a single tertiary gastroenterology center were prospectively included in this study.METHODS:116 patients with Rome III IBS score (76 females; 48 ± 12 years) were investigated; 24 patients (15 females) had PI-IBS. Intestinal inflammation was assessed using the semiquantitative fecal calprotectin test. The results were expressed as T1, T2 or T3 according to the severity of inflammation (< 15 μg/g; 15-60 μg/g; > 60 μg/g). Using the same test, we evaluated 20 patients with IBD (12 males; 47 ± 13 years).RESULTS:None of the patients with IBS had a T2 or T3 positive test. Among PI-IBS patients, 33% had a T1 positive test. Among NPI-IBS patients, 9.8% had a T1 positive test, which was significantly different to PI-IBS. The calprotectin test was positive in all IBD patients: 80% with T3, 10% with T2 and 10% with T1.CONCLUSIONS:Using a semiquantitative test for fecal calprotectin, positive tests were more frequent in PI-IBS patients than in NPI-IBS patients.

CONTEXTO E OBJETIVO:A presença de certo grau de inflamação na parede do intestino é agora aceita na síndrome do intestino irritável (SII). A calprotectina fecal é considerada teste confiável para detectar inflamação intestinal. Nosso objetivo foi avaliar a presença de inflamação na SII pós-infecciosa (SII-PI), em comparação com a SII não pós-infecciosa (SII-NPI). Um objetivo secundário foi determinar a utilidade de um teste rápido fecal da calprotectina em doenças inflamatórias intestinais (DII).TIPO DE ESTUDO E LOCAL:Este foi um estudo transversal. Pacientes com SII e DII em um único centro terciário de gastroenterologia foram prospectivamente incluídos neste estudo.MÉTODOS:116 pacientes com escore Roma III de SII (76 mulheres, 48 ± 12 anos) foram investigados; 24 pacientes (15 mulheres) tinham SII-PI. Inflamação intestinal foi avaliada pelo teste semi-quantitativo de calprotectina fecal. Os resultados foram expressos como T1, T2 ou T3 de acordo com a gravidade da inflamação (< 15 μg/g; 15-60 mg/g; > 60 mg/g). Usando o mesmo teste, foram avaliados 20 pacientes com DII (12 homens, 47 ± 13 anos).RESULTADOS:Nenhum dos pacientes com SII teve um teste positivo T2 ou T3. Na PI-IBS, 33% tiveram um teste positivo T1. Entre os pacientes SII-NPI, teste T1 positivo estava presente em 9,8%, taxa significativamente diferente quando comparada com SII-PI. O teste de calprotectina foi positivo em todos os pacientes com DII: 80% com T3, 10% com T2 e 10% com T1.CONCLUSÕES:Usando teste semi-quantitativo para calprotectina fecal, relatamos positividade em pacientes SII-PI com mais frequência que em pacientes SII-NPI.

Data analysis: absolute and relative frequencies for qualitative variables; measures of central tendency and dispersion for quantitative. Excel 2011 and Epi-info program. Results: There were 826 children hospitalized for acute gastroenteritis, hospitalization was rate 122 / thousand. Income from gastroenteritis represents 12.3% of total annual revenue. Average age: 3 months. Enteric pathogens were isolated in 20% of the samples studied: Rotavirus 7.9%, Campylobacter 5.9% and Norovirus 1.6%. Dehydration was the most frequent reason for 59% income. There were no deaths. Conclusions: This ongoing pathology is a frequent reason for hospitalization. Rotavirus was mostly isolated germ. First National description of Norovirus causative agent of gastroenteritis in children. There were significant clinical associations with enteropathogens such as rotavirus, norovirus and campylobacter.

Exantema macular en un niño con gastroenteritis por rotavirus: informe de caso / Macular exanthema in a child with rotavirus gastroenteritis: a case report

Aparte de la gastroenteritis, raramente se ha implicado al rotavirus en otros trastornos cutáneos como el exantema maculopapular generalizado, el edema hemorrágico agudo del lactante y el síndrome de Gianotti-Crosti. Comunicamos el caso de un niño de 30 meses de edad que presentó erupciones cutáneas maculares eritematosas mientras cursaba una gastroenteritis por rotavirus. En nuestro conocimiento, este es el primer caso en la bibliografía en el que se informan lesiones maculares eritematosas asociadas a rotavirus en un paciente pediátrico. En consecuencia, deseamos compartir nuestra experiencia para que se considere la infección por rotavirus dentro del diagnóstico diferencial de los niños que presenten gastroenteritis y erupción eritematosa.

Apart from gastroenteritis, rotavirus has been rarely implicated with some cutaneous disorders such as generalized maculo-papular exanthema, infantile acute hemorrhagic edema and Gianotti-Crosti syndrome. We report a 30-month old toddler boy who developed erythematous macular skin eruptions during the course of rotavirus gastroenteritis. To our knowledge, this is the first case in the literature reporting rotavirus-related macular erythematous lesions in a pediatric patient. We therefore would like to share our experience, to keep ro-tavirus infection in the differential diagnosis of children with gastroenteritis and erythematous eruption.

Prevalence of Human Astrovirus in Patients with Acute Gastroenteritis

The prevalence of human astroviruses was tested in patients with acute gastroenteritis by using conventional duplex reverse transcription (RT)-PCR and electrophoresis. Diarrheal fecal samples were collected from 9,597 patients at local hospitals in Seoul. The prevalence of astroviruses was 1.0% (94/9,597 patients; mostly infants), and that of sapoviruses was 0.1% (14/9,597 patients). Age- and gender-wise analyses were carried out on 29 astrovirus-positive patients having complete information on file regarding their age, gender, and other particulars. The results were higher in patients of ages 0 to 14 yr, and 69.0% of the astrovirus-positive patients were females, of which 69.2% were infants (0 to 12 months), and 61.5% were 1-4 yr old. Notably, in the case of 5 to 78-yr-old acute gastroenteritis patients, 100% were females.

Una causa infrecuente de convulsión afebril: gastroenteritis por rotavirus / A rare cause of afebrile convulsion: rotavirus gastroenteritis

La gastroenteritis por rotavirus es la más frecuente de las diarreas infecciosas y ocasiona una importante morbimortalidad en los niños pequeños, además de deshidratación grave y desequilibrios electrolíticos; los signos extraintestinales son infrecuentes. Recientemente se han comunicado convulsiones afebriles asociadas con gastroenteritis por rotavirus, sin encefalopatía, deshidratación, desequilibrio electrolítico o hipoglucemia. Comunicamos el caso de un paciente con convulsiones durante una gastroenteritis por rotavirus, una infección habitual en nuestro país (Turquía), con diversas manifestaciones clínicas, entre ellas, las convulsiones, que pueden verse no sólo en los niños con enfermedades neurológicas o sistémicas sino también en los niños sanos.

Rotavirus is the most common infectious diarrhea that causes important mortality and morbidities in small children, severe dehydration and electrolyte imbalance. Extraintestinal signs are rare in rotavirus infections. Recently, afebrile seizures associated with rotavirus gastroenteritis but without encephalopathy, dehydration, electrolyte imbalance or hypoglycemia have being reported. In this article, the fact that rotavirus, which is seen commonly in our country, can be confronted with various clinical manifestations was emphasized by reminding that it can be seen not only in infants with neurologic and systemic disease but also in healthy infants.

Boerhaave's syndrome: a differential diagnosis of acute chest pain following a vomiting illness / Síndrome de Boerhaave: un diagnóstico diferencial de dolor torácico, agudo tras enfermedad acompañada de vómitos

Spontaneous oesophageal rupture (Boerhaave's syndrome) is extremely rare in children. Presentation is usually in middle aged men as a result of vomiting following heavy food or alcohol consumption. We describe an unusual case of a 12-year old boy without significant past medical history presenting with acute chest pain following gastroenteritis.

La ruptura esofágica espontánea (síndrome de Boerhaave) es extremadamente rara en niños. Por lo general se presenta en hombres de mediana edad como resultado vómitos tras la ingestión de alcohol o alimentos pesados. Describimos un caso inusual de un niño de 12 años de edad sin antecedentes clínicos significativos, que acudió con dolor torácico agudo tras una gastroenteritis.

Síndrome do intestino irritável pós-infecção intestinal / Irritable bowel syndrome after intestinal infection

A síndrome do intestino irritável (SII) é um distúrbio funcional do trato gastrointestinal, caracterizado por dor abdominal e alterações do hábito intestinal, não explicadas por anormalidades bioquímicas ou orgânicas. Embora a maioria dos pacientes relate início insidioso dos sintomas, em um subgrupo eles aparecem após episódio de gastroenterite aguda, denominada SII pós-infecciosa (SII-PI). Os agentes infecciosos envolvidos incluem vírus, parasitas e bactérias patogênicas. O tratamento da SII-PI é semelhante ao da SII idiopática. Antibióticos e probióticos são terapias promissoras

Irritable bowel syndrome (IBS) is a funcional gastrointestinal disorder characterized by abdominal pain and changes in bowel habits, not explained by any organic or biochemical abnormalities. Although most patients describe an insidious onset of symptoms, a subgroup of individuals describes the onset of IBS symptoms following an episode of acute gastroenteritis, know as post-infectious IBS (PI-IBS). The infectious agents involved in the development of PI-IBS include pathogenic bacteria, parasites and viruses. Treatment of PI-IBS is similar to that idiopathic IBS. Antibiotics and probiotics appear to represent promising therapies in PI-IBS

[A new clinical entity: Post-infectious irritable bowel syndrome]

Post-infectious irritable bowel syndrome [PI-IBS] is a disorder wherein symptoms of IBS begin after an episode of acute gastroenteritis. To determine epidemiology, clinical features and prognosis of PI-IBS and to precise its physiopathology and treatment. Literature review. Published studies have reported an incidence of PI-IBS ranging from 4 to 32% with a mean of 10%. Bacterial infections are the most responsible agents. Risk factors for PI-IBS include patient's demographics, psychological disorders and the severity of enteric illness. The most common symptoms are those of diarrheapredominant IBS. The mechanisms underlying PI-IBS include especially changes in intestinal permeability and persistent mucosal inflammatory process. In fact, there is increase in lymphocytic, mast and enterochromaffin cells in the gut mucosa. Furthermore, increased inflammatory cytokines have been demonstrated. Treatment of PIIBS is similar to that idiopathic IBS. PI-IBS is a novel clinic entity that suggests a novel approaches to IBS

Incidence and Risk Factors of Irritable Bowel Syndrome in Community Subjects with Culture-proven Bacterial Gastroenteritis / 대한소화기학회지

BACKGROUND/AIMS: The aim of this study was to investigate the incidence and risk factors of irritable bowel syndrome (IBS) in community subjects with culture-proven bacterial gastroenteritis. METHODS: This was a prospective, community-based, cohort study, which followed patients with a recent history of culture-proven bacterial gastroenteritis. IBS was diagnosed with the use of the Rome II criteria at 3 and 6 months after bacterial dysentery. RESULTS: Sixty five cases were included and completed the 6 month follow-up. Thirty four cases (52.3%) were female. Salmonella was the pathogen most frequently identified and seen in 41 patients (63.1%). The cumulative incidence of IBS among patients with microbiologically proven bacterial gastroenteritis within a community was 9.2% and 12.3% at 3 and 6 months of follow-up, respectively. The duration of initial diarrhea (> or =7 days) was associated with an increased risk for the development of IBS (aOR, 14.50 [95% CI, 1.38-152.72]; p=0.022). CONCLUSIONS: Our study suggests that the incidence of IBS among patients with culture-proven bacterial gastroenteritis within a community is similar to that reported among Western populations. A large, prospective study is encouraged to confirm our results and to evaluate the influence of the microbial species on the epidemiology of IBS in Asian populations.

Bacteremia Caused by Laribacter hongkongensis Misidentified as Acinetobacter lwoffii: Report of the First Case in Korea

Laribacter hongkongensis is an emerging pathogen in patients with community-acquired gastroenteritis and traveler's diarrhea. We herein report a case of L. hongkongensis infection in a 24-yr-old male with liver cirrhosis complicated by Wilson's disease. He was admitted to a hospital with only abdominal distension. On day 6 following admission, he complained of abdominal pain and his body temperature reached 38.6degrees C. The results of peritoneal fluid evaluation revealed a leukocyte count of 1,180/microL (polymorphonuclear leukocyte 74%). Growth on blood culture was identified as a gram-negative bacillus. The isolate was initially identified as Acinetobacter lwoffii by conventional identification methods in the clinical microbiology laboratory, but was later identified as L. hongkongensis on the basis of molecular identification. The patient was successfully treated with cefotaxime. To the best of our knowledge, this case is the first report of hospital-acquired L. hongkongensis bacteremia with neutrophilic ascites.

A Case of Limited Wegener's Granulomatosis with Gastroenteritis and Mesenteric Lymphadenopathy / 대한소화기학회지

Wegener's granulomatosis (WG) is a disease characterized by a granulomatous necrotizing vasculitis of small vessels. Although any organ systems can be involved, gastrointestinal involvement in WG is notably uncommon. We present a case of 67-year-old man who was admitted with abdominal pain and diarrhea lasting for 3 weeks. Colonoscopy and abdominal CT scan revealed vasculitis and multiple mesenteric lymphadenopathy. Jejunum and mesenteric lymph nodes biopsies confirmed limited form of WG. The present case indicates that WG might involve only gastrointestinal tract and the histological confirmation is important for diagnosis.

Non-rotavirus infection causing apnea in a neonate.

Apnea in a premature infant is not always due to immaturity and caffeine is not always the answer. We report a case of apnea in a preterm infant who presented at two weeks of life with increase in frequency of apnea that did not respond to caffeine. Family history was significant for diarrhea in a sibling. Stool PCR was positive for Norovirus Genogroup II. Enteric isolation was instituted and the apnea resolved spontaneously with conservative management. Re-emergence of apnea or persistent apnea necessitates further investigation to elucidate the etiology.

A study of abdominal pain in children.

Pain abdomen is a common pediatric complaint that brings patient to the hospital in Nepal. Knowledge about its etiology and frequency helps in its evaluation and management. The present study was undertaken to find out the causes and their frequency of pain abdomen in Nepali children. Children with pain abdomen presenting at the emergency room and pediatric outpatient department of Kathmandu Medical College, Kathmandu from January, 2006 to December 2007 were clinically evaluated and investigated to find out the causes and frequency of their pain abdomen. The outcomes were tabulated and analyzed for interpretation. Of 444 patients attended, 356 completed investigations and came for follow up. Cause of pain abdomen was apparent in 117 (32.9%) only. 91.5% were medical causes, comprising predominantly of diarrheal diseases (28.3%), infantile colic (9.4%), urinary tract infection (7.7%) and acid peptic disease (6.8%). 8.5% causes were related to surgical conditions, which needed operative management. Secondary or extra-abdominal causes were found in 20 cases (17.1%). Pneumonia (2), functional (5), vulvovaginitis (2) and infantile colic (11) were predominant causes. Our study showed that the causes of pain abdomen in children were predominantly medical. Gastroenteritis was the most frequent cause. Secondary causes, including functional and emotional causes were infrequent. Small percentage needing surgical management formed a diagnostic challenge.

Enterobiliary Fistula as a Complication of Eosinophilic Gastroenteritis: a Case Report

Eosinophilic gasteroenteritis is an uncommon disease with variable clinical features characterized by eosinophilic infiltration. Clinical manifestations range from non-specific gastrointestinal complaints such as nausea, vomiting, crampy abdominal pain, and diarrhea to specific findings such as malabsorption, protein loosing enteropathy, luminal obstruction, eosinophilic ascites and effusion. We report here on a case of eosinophilic gastroenteritis causing enterobiliary fistula which is an extremely unusual complication.
