A dor abdominal no paciente com lúpus eritematoso sistêmico tem amplo espectro clínico, variando desde condições inespecí- ficas, como diarreia e vômitos, até eventos de importante morbi- mortalidade, como o abdome agudo inflamatório e/ou perfura- tivo. A seguir, descreve-se um caso de paciente do sexo feminino, de 23 anos, internada por dor abdominal associada a vômitos e à diarreia crônica e progressiva. Foi diagnosticada com lúpus eritematoso sistêmico há 2 anos. Durante a internação, evoluiu com quadro de abdome agudo, e foi realizada tomografia compu- tadorizada de abdome, revelando importante edema de parede intestinal difuso. Isso, somado a alterações clínico-laboratoriais, permitiu o diagnóstico de enterite lúpica. Foi realizado tratamen- to conservador, com corticoterapia e terapia de suporte com correção de distúrbios eletrolíticos severos, sendo iniciado ciclo- fosfamida, com resolução dos sintomas gastrintestinais.
Abdominal pain in patients with systemic lupus erythematosus has a broad clinical spectrum, ranging from nonspecific symp- toms, such as diarrhea and vomiting, to events of significant morbidity and mortality, such as acute inflammatory and/or per- forating abdomen. This article describes a case of a 23-year-old female patient hospitalized for abdominal pain, associated with vomiting and progressive chronic diarrhea. She was diagnosed with systemic lupus erythematosus 2 years ago. During hospita- lization, the patient progressed with acute abdomen, and an ab- dominal computed tomography scan was performed, revealing major diffuse intestinal wall edema. This, added to clinical and laboratories alterations, allowed the diagnosis of lupus enteritis. A conservative treatment with corticotherapy and supportive therapy with correction of severe electrolyte disturbances were initiated, as well as the prescription of cyclophosphamide, with resolution of gastrointestinal symptoms.

RESUMEN La enteritis eosinofílica consiste en la presencia de infiltrados eosinofílicos en el tracto digestivo. Constituye en la actualidad una entidad rara que puede localizarse en cualquier región del tubo digestivo. Su etiopatogenia se desconoce y en muchas ocasiones se relaciona con antecedentes de atopia. Las manifestaciones clínicas varían en función de las capas afectadas. Se presentó el caso de un paciente de 26 años de edad, con antecedentes de haber sido operado de apendicitis aguda, en el año 2011. Llegó al Cuerpo de Guardia refiriendo dolor intenso, fijo; en fosa iliaca derecha, acompañado de fiebre de 39°C, con escalofríos y síntomas dispéptico. Se orientó ingreso y se le realizó una videoendoscopia, se observó gastritis antral eritematosa exudativa con test para Helicobacter pylori positivo. Además, una videolaparoscopia arrojando presencia de asas delgadas apelotonadas y adherencias no recientes en fosa iliaca derecha. A pesar del tratamiento empleado el paciente continuó con dolor y fiebre, por lo que se decidió indicarle una enteroscopia de doble balón con biopsia de íleon. Se informó que a nivel del colon presentaba una colitis crónica inespecífica y en el íleon una hiperplasia linfoide. El estudio histopatológico confirmó la colitis inespecífica y una eosinofilia moderada en íleon. Se indicó tratamiento con prednisona y mesalazina con mejoría notable del cuadro clínico, fue dado de alta con el diagnóstico de una enteritis eosinofílica, con seguimiento por consulta externa de gastroenterología. En la actualidad se mantiene asintomático (AU).
ABSTRACT Eosinophilic enteritis is the presence of eosinophilic infiltrates in the digestive tract. Currently it is a rare entity than could be located in any region of the digestive tract. Its etiopathogenesis is unknown and is related, in many cases, to antecedents of atopy, Clinical manifestations may vary according to the affected layer. The authors present the case of a patient aged 26 years, with antecedents of having undergone an acute appendicitis surgery in 2011. He arrived to Emergency referring intense, steady pain in the right iliac fossa, accompanied by a 39o C fever, chills and dyspeptic symptoms. He was admitted and a video endoscopy was carried out. An exudative erythematous antral gastritis was observed with a positive test for Helicobacter pylori. In addition, video laparoscopy also showed the presence of thin, lumped loops and no-recent adherences in the right iliac fossa. In spite of the applied treatment, the patient continued with pain and fever, so the doctors indicated a double-balloon enteroscopy with ileum biopsy. It was informed an unspecific chronic colitis at the colon level and a lymphoid hyperplasia in the ileum. The histopathologic study confirmed the unspecific colitis and a moderate eosinophilia in the ileum. A prednisone and mesalazine treatment was indicated with a notable improvement of the clinical characteristics. The patient was discharged diagnosed with a eosinophilic enteritis and follow-up in out-patient consultation of Gastroenterology. Currently he keeps on asymptomatic (AU).

RESUMEN La gastroenteritis eosinofílica (EG) es una entidad poco frecuente. Presentamos un varón de 55 años sin antecedentes de atopía ni alergia, que presentó dolor abdominal y vómitos. La tomografía computarizada abdominal y la ecoendoscopia demostraron engrosamiento de la pared gástrica con engrosamiento de la pared del duodeno superior, sin masa definida ni colección de líquido. La endoscopia gastrointestinal confirmó engrosamiento de pliegues prepilóricos y duodeno superior con estenosis luminal. Se realizó gastrectomía parcial por ausencia de diagnóstico definitivo y sospecha de posible malignidad y diagnóstico de obstrucción de la salida gástrica. La histopatología fue compatible con EG, tratada con un tratamiento con corticoides de 8 semanas de duración, mostró mejoría clínica, aumento de peso y normalización del recuento de eosinófilos en sangre periférica.
ABSTRACT Eosinophilic gastroenteritis (EG) is a rare entity. We report a 55-year-old man had no previous atopy or allergic history, who presented abdominal pain and vomiting. Abdominal computed tomography and endoscopy ultrasonography demostrated gastric wall thickening with wall thickening of the superior duodenum, without defined mass or fluid collection. Gastrointestinal endoscopy confirmed thickening of prepyloric folds and superior duodenum with luminal stenosis. Parcial gastrectomy was performed due to absence of definitive diagnosis and suspicion of possible malignancy and diagnosis of gastric outlet obstruction. Histopathology was compatible with EG, treated with an 8-week long corticosteroid therapy, showed clinical improvement, weight gain and normalization of eosinophil count on peripheral blood.

In lupus enteritis, circulating pathological immune complexes and thrombosis of intestinal vessels may occur, resulting in acute abdominal pain. We report a 24-year-old woman without a history of systemic lupus erythematosus (SLE), admitted for abdominal pain. An exploratory laparotomy found an appendicitis along with ascites. An appendectomy was performed, and the patient was discharged from the hospital two days later. Three days after discharge, the patient was admitted to another hospital due to the persistence of abdominal pain. An abdominal computed tomography scan showed diffuse mesenteric congestion, concentric bowel loops (double halo or target sign) and the presence of free fluid in the peritoneal cavity. Suspecting a rheumatic disorder, the diagnosis of SLE was confirmed by immunological studies. The patient was treated with pulses of methylprednisolone with good results.

Although gastrointestinal symptoms are not rare in Systemic lupus erythematosus, enteritis is an atypical manifestation of the disease. We report a 54 year-old woman who presented acute symptoms of diarrhea, fever and abdominal pain, receiving empiric antibiotic therapy for bacterial enteritis with no response. Computed tomography showed diffuse small intestine inflammation and serositis. Antinuclear antibodies, anti-Ro and anti-La were positive on blood tests. A lupic enteropathy was diagnosed and steroid treatment was initiated, with subsequent clinical improvement.

La gastroenteritis eosinofílica es una enfermedad primaria rara caracterizada por abundante infiltrado eosinofílico en la mucosa intestinal. Se presenta con síntomas gastrointestinales diversos e inespecíficos de acuerdo a la profundidad de la afección de la mucosa, llegando a complicaciones severas. Se reporta el caso de una paciente de 52 años sin antecedentes previos con 8 meses de diarrea, dolor abdominal, ascitis y pérdida de peso. Tras realizarse los exámenes de rutina y descartarse todas las patologías más frecuentes, se llega al diagnóstico. La gastroenteritis eosinofílica requiere una alta sospecha diagnóstica y los síntomas crónicos generan gran impacto en el estado nutricional y calidad de vida del paciente, por lo cual instamos a los médicos a revisar el tema y considerarlo dentro del diagnóstico diferencial de diarrea y dolor abdominal crónicos no específicos.
Eosinophilic gastroenteritis is a rare primary disease distinguished by abundant eosinophilic infiltration of the intestinal mucosa. It concerns variable and nonspecific gastrointestinal symptoms according to the depth of infiltration and may cause severe complications. We reported a case of a 52-year-old woman without prior diseases with 8-month history of diarrhea, abdominal pain, ascites and weight loss. After having performed routine tests and rolled out most common diseases, we get to the diagnosis. Eosinophilic gastroenteritis requires a high suspicion for the diagnosis; because of chronic symptoms, it shows a burden on the nutritional status and quality of life of patients. Therefore, it is imperative that physicians should review this topic and consider it within differential diagnosis of chronic diarrhea and abdominal pain

La cápsula endoscópica es un método, que ha modificado el enfoque diagnóstico de numerosos procesos patológicos en el intestino delgado, sin embargo presenta complicaciones como la retención de la misma. Se estima en la literatura mundial que esta suele ocurrir en menos del 2% de los casos. Femenino de 40 años de edad, con antecedente de cáncer de cuello uterino (2011) en tratamiento con quimioterapia, radioterapia convencional y braquiterapia, que presenta cuadro clínico caracterizado por dolor urente en mesogastrio, y emesis de aspecto biliosos. Ruidos hidroaéreos presentes, dolor a la palpación de mesogastrio sin irritación peritoneal. Radiografía de abdomen y ecosonograma abdominal normales. TAC abdomino pélvica con contraste oral con adecuada progresión de contraste hasta el recto. Se practica gastroscopia y colonoscopia sin evidencia de alteraciones. En vista de persistencia de sintomatología se indica realización de cápsula endoscópica observando en íleon distal, a los 246 minutos del paso duodenal, área muy congestiva, con una úlcera circunferencial friable, que no permite el avance de la misma. Se indica tratamiento médico con laxantes por 72 horas, el cual es infructuoso, por lo cual es llevada a mesa operatoria por presentar signos francos de obstrucción intestinal. Los hallazgos fueron: adherencias en flanco y fosa ilíaca derecha, las cuales fueron liberadas, y segmento de íleon a 10 cm de la válvula ileocecal con inflamación franca, practicándose resección y anastomosis termino-lateral. El estudio histopatológico reportó enteritis crónica activa exulcerada, necrosis fibrinoide de pequeños vasos, y fibrosis en la submucosa. Paciente con post-operatorio exitoso decidiéndose el egreso de la institución. Excelente correlación entre los hallazgos de la cápsula endoscópica y la intervención quirúrgica. Los hallazgos de la cirugía se encuentran relacionados al uso de radioterapia convencional, por lo cual recomendamos la realización de pexia...
Capsule endoscopy is a method that has changed the diagnostic approach to many pathological processes in the small intestine, but it has complications such as retention of the same, is estimated in the literature that this usually occurs in less than 2% cases. Women 40 years of age, with a history of cervical cancer (2011) undergoing chemotherapy, conventional radiation therapy, and brachytherapy, presenting clinical picture characterized by burning pain in midgut, and bilious emesis aspect. Present bowel sounds, tenderness of mesogastrium without peritoneal irritation. Abdominal radiography and abdominal ultrasonography normal. Pelvic CT with oral contrast Abdomino with progression adequate contrast to the rectum. Gastroscopy and colonoscopy was performed without evidence of tampering. In view of the persistence of symptoms embodiment shown in watching endoscopic capsule distal ileum, to 246 minutes of step duodenal study, very congestive area with a circumferential friable ulcer which does not allow the advance thereof. Indicated medical treatment with laxatives for 72 hours being fruitless, operating table being carried by presenting overt signs of intestinal obstruction. The findings were: adhesions flank and right lower quadrant, which were released and ileal segment 10 cm from the ileocecal valve with frank inflammation resection and end-side anastomosis. Histopathological study reported chronic active enteritis exulcerada, fibrinoid necrosis of small vessels, and fibrosis in the submucosa. Postoperative patient deciding successful graduation from the institution. Excellent correlation between the findings of capsule endoscopy and surgery. The findings at surgery are related to the use of conventional radiotherapy, so we recommend an pexia of the organs that are in the radiation field, prior to it, and intestinal transit before indicating capsule endoscopy

A molecular study of intestinal samples from 21 broiler flocks with a history of enteritis revealed that 23.8% and 14.3% were positive for chicken astrovirus (CAstV) and avian rotavirus (ARV), respectively. CAstV and group A ARV were simultaneously detected in only one broiler flock. Birds in this group developed the significant intestinal lesions characterized by frothy contents, paleness, and thin intestinal walls. In this report we present an unusual case of runting stunting syndrome (RSS) with a history of high mortality and growth retardation in broiler chickens. We also make the first identification of CAstV and group A ARV in broiler chickens in Korea.

Cytomegalovirus (CMV) infections are usually diagnosed in immunocompromised patients. A 74-year-old male without any significant medical history visited our center because of abdominal pain and diarrhea which began about a month ago. Abdominal computed tomography revealed segmental enhanced bowel wall thickening on jejunum and single-balloon enteroscopy showed multiple geographic shaped ulcerations covered with exudates on proximal jejunum. Biopsy samples taken during endoscopic examination demonstrated necrotic fibrinopurulent tissue debris and benign ulcer. Nested-PCR analysis of CMV DNA from jejunal tissue was positive. The patient was finally diagnosed with CMV jejunitis and was treated by intravenous ganciclovir for 14 days after which, abdominal pain and diarrhea improved. Our case shows that CMV jejunitis can occur in an immunocompetent adult as multiple jejunal ulcers which can be diagnosed using a single-balloon enteroscope.

There are various etiologies of duodenojejunitis such as Henoch-Schonlein purpura (H-S purpura), vasculitis, Crohn's disease, celiac sprue, ischemia, lymphoma, Zollinger-Ellison syndrome, bacteria or parasite infection, radiation, drug induced jejunitis, eosinophilic jejunitis, and toxins. A 31-year-old man presented with left upper quadrant pain. He did not have febrile sense, hematochezia, melena, diarrhea, arthralgia and hematuria. He had neither drug history nor traveling history. Esophagogastroduodenoscopy showed diffuse mucosal erythema and segmental hemorrhagic erosions on the distal area to the descending portion of the duodenum and proximal jejunum, which were commonly observed in the gastrointestinal involvement of H-S purpura. However, he showed no skin lesions, joint and urologic problems until the discharge. Autoimmune markers such as antinuclear antibody and antineutrophil cytoplasmic antibody were negative. Celiac and mesenteric angiogram showed no vascular abnormality. After the administration of oral prednisolone 40 mg daily for therapeutic trial, abdominal pain and endoscopic lesions were improved. He experienced relapses of same episode without skin lesions 16 times during follow-up of 8 years, which were also treated with prednisolone. The abdominal computed tomography during the follow-up also showed no significant finding. We report a case of primary recurrent duodenojejunitis similar to the gastrointestinal involvement of H-S purpura without purpura.

Cryptogenic multifocal ulcerous stenosing enteritis (CMUSE) is a rare pathology with no more than 30 reported cases worldwide. The diagnosis requires a combination of clinical elements, imagenological and histological, and to rule out other pathologies. This is the case of a 36 year-old patient presenting anemia, abdominal pain and diarrhea related to immune manifestations with a CMUSE diagnosis. Double balloon enteroscopy was a critical tool for the diagnosis. The patient showed a good response to steroidal treatment with symptomatic remission.
La enteritis estenosante y ulcerativa multifocal idiopática (CMUSE) es una entidad poco frecuente con no más de 30 casos reportados a nivel mundial. El diagnóstico requiere una combinación de elementos clínicos, imagenológicos e histológicos, y descartar otras patologías. Presentamos el caso de una paciente de 36 años que se presenta con anemia, dolor abdominal y diarrea asociado a manifestaciones inmunológicas con diagnóstico de CMUSE. La enteroscopia Doble Balón fue una herramienta fundamental para el diagnóstico. Evolucionó con buena respuesta a tratamiento esteroidal con remisión sintomática mantenida.

We describe an elderly male who had a two day history of fever, abdominal pain and watery loose motions. Clinical examination was positive for abdominal right lower quadrant tenderness and moderate dehydration. Stool examination revealed inflammatory diarrhea. Considering the high prevalence of extended spectrum β-lactamases (ESBL) producing Gram-negative infections, he was treated with Piperacillin/Tazobactam. Surprisingly, his blood culture which was taken on admission returned positive for Streptococcus pneumoniae after two days, which was coincident with resolution of fever and diarrhea. This patient had no other clinically apparent source of Pneumococcal infection and we believe that he had Pneumococcal enteritis with bacteremia. There are very few reported cases of isolated Pneumococcal enteritis in the literature. Therefore, we report this unusual form of Streptococcus pneumoniae infection both because of its rarity and its potentially life-threatening but still curable nature. ©

Cochlosoma sp. infection was identified in a single case among 60 stunted diarrheic native turkey poults, Meleagris galopavo. A large number of the flagellated parasites was found free or within the intervillous spaces of the jejunum, ileum and cecum. Moderate enteritis was associated with the parasites. In TEM studies of the parasagittal sections of the parasite, a prominent ventral sucker like disc and flagella emerging from an opening on the ventrodorsal surface of the pyriform uninuclear parasite were found. The morphological characteristics of this protozoan match with those described for Cochlosoma anatis. The parasite could be considered as an intestinal pathogenic protozoan causing stunting and diarrhea in turkeys in Iran.

Sapovirus of the Caliciviridae family is an important agent of acute gastroenteritis in children and piglets. The Sapovirus genus is divided into seven genogroups (G), and strains from the GIII, GVI and GVII are associated with infections in swine. Despite the high prevalence in some countries, there are no studies related to the presence of porcine enteric sapovirus infections in piglets in Brazil. In the present study, 18 fecal specimens from piglets up to 28 days were examined to determine the presence of sapovirus genome by RT-PCR assay, using primers designed to amplify a 331 bp segment of the RNA polymerase gene. In 44.4 percent (8/18) of fecal samples, an amplified DNA fragment was obtained. One of these fragments was sequenced and submitted to molecular and phylogenetic analysis. This analysis revealed high similarity, with nucleotides (87 percent) and amino acids (97.8 percent), to the Cowden strain, the GIII prototype of porcine enteric calicivirus. This is the first description of sapovirus in Brazilian swine herds.
O sapovírus classificado na família Caliciviridae é um importante causador de gastroenterite aguda em crianças e leitões. O gênero Sapovirus é dividido em sete genogrupos (G), sendo que as estirpes dos GIII, GVI e GVII estão associadas com infecção em suínos. Apesar da alta prevalência da infecção em alguns países, ainda não existem estudos referentes à presença do calicivírus entérico suíno nos rebanhos brasileiros. No presente estudo 18 amostras de fezes de leitões com até 28 dias foram avaliadas pela RT-PCR para a presença do genoma do sapovírus, utilizando os primers desenvolvidos para amplificar um segmento de 331 pb do gene da RNA polimerase viral. Em 44,4 por cento (8/18) das amostras foi amplificado um fragmento de DNA. Um desses amplicons foi seqüenciado e pela análise molecular e filogenética foi verificada similaridade de 87 por cento em nucleotídeos e 97,8 por cento em aminoácidos com a estirpe Cowden, protótipo do GIII. Esta é a primeira descrição do sapovírus em rebanhos suínos brasileiros.

Oito amostras de Escherichia coli isoladas de papagaios com colibacilose aviária foram sorogrupadas e investigadas para a presença dos fatores de virulência: pili associado a pielonefrite (pap), fímbria S (sfa), adesina afimbrial (afa), cápsula K1 (neu), curli (crl, csgA), hemaglutinina termosensível(tsh), enterotoxinas termo-lábil (LT) e termo-estável (STa eSTb), Shiga-like toxinas (Stx1 e Stx2), Fator citotóxico necrotizante(cnf1), hemolisina (hly), aerobactina (iuc) e resistência sérica (iss). Os resultados mostraram que os isolados pertenciam a seis sorogrupos:O23; O54; O64; O76; O128 e O152. Os genes de virulência detectados foram: crl+ em todos os isolados; pap+; iss+ e iuc+ em três isolados, tsh+em dois isolados. Todas as amostras foram negativas para os genes neu, csgA, sfa, afa, hly, cnf e para as toxinas LT, STa, STb, Stx1 e Stx2.Estes resultados sugerem que amostras de E. coli isoladas de papagaios apresentam alguns fatores de virulência das amostras do patotipo de E. coli patogênica para aves (APEC).
A total of eight Escherichia. coli isolates from psittacine birds were serogrouping and investigated for the virulence factors: pili associated with pyelonephritis (pap), S fimbriae (sfa), afimbrial adhesin (afa), capsule K1 (neu), curli fibers (crl, csgA), temperature-sensitive hemagglutinin (tsh), heat labile (LT) and heat stable (STa and STb)enterotoxins, Shiga-like toxins (Stx1 and Stx2), Cytotoxic necrotizing factor (cnf1), haemolysin (hly), aerobactin production (iuc) and serum resistance (iss). The results showed that the isolates belonged to six serogroups: O23; O54; O64; O76; O128 and O152. The found virulence genes were: crl+ in all isolates, pap+, iuc+ and iss+ in three isolates; tsh+ in two isolates. All strains were negative for genes neu,csgA, sfa, afa, hly, cnf and LT, STa, STb, Stx1, Stx2 toxins. Our findings suggested that some E. coli isolated from psittacine birds present some virulence factors of avian pathogenic E. coli (APEC) pathotype.

This paper relates the clinical and epidemiological aspects of canine parvovirus infection (CPV) in the State of Rio de Janeiro from April 1995 to March 2004. A total of 341 fecal samples were collected from up to 6-months-old puppies with gastroenteritis. The diagnosis of CPV infection was confirmed by hemagglutination/ hemagglutination inhibition tests, enzyme immunoassay, virus isolation in cell culture or polymerase chain reaction. One hundred and fifty-seven samples (46 percent) were positive for CPV. No correlation among sex, breed or age and the occurrence of CPV infection was observed. The classical signs of parvoviral enteritis (anorexia, lethargy, vomiting and hemorrhagic fluid diarrhea) were observed in 70 percent of CPV-positive and in 60 percent of CPV-negative puppies. Although CPV could be detected throughout the studied period, its occurrence was significantly higher from June to September and November to December. These results show that CPV is still circulating in the State of Rio de Janeiro.
Este trabalho relata os aspectos clínicos e epidemiológicos da infecção pelo CPV no Estado do Rio de Janeiro, no período de abril de 1995 a março de 2004. Coletaram-se 341 amostras fecais de cães com até seis meses de idade que apresentavam gastrenterite. O diagnóstico da infecção pelo CPV foi confirmado através dos testes de hemaglutinação/inibição da hemaglutinação, ensaio imunoenzimático, isolamento viral em cultura de células ou reação em cadeia pela polimerase. Cento e cinqüenta e sete amostras (46 por cento) foram consideradas positivas para CPV. Não foi observada correlação entre sexo, raça ou idade e a ocorrência da infecção por CPV. Os sinais clínicos clássicos de parvovirose (vômito, anorexia, apatia e diarréia líquida hemorrágica) foram observados em 70 por cento dos animais positivos e 60 por cento dos animais negativos para CPV. O CPV foi detectado ao longo do período estudado, entretanto observou-se um aumento do número de casos positivos nos períodos de junho a setembro e novembro a dezembro. Estes resultados mostram que o CPV ainda circula no Estado do Rio de Janeiro.

The anatomic variations of the appendix along with a wide spectrum of appendiceal affections frustrate the accurate diagnosis of appendicitis. Isolated endometriosis of the appendix is rare and its presentation as acute appendicitis is even uncommon[1] Endometriosis affects the intestinal tract in 15-30% of patients with pelvic endometriosis[2]. The correct diagnosis is often delayed because intestinal endometriosis may masquerade clinically as regional enteritis, ischemic enteritis or colitis, diverticulitis or neoplasm[3,4]. The incidence of endometriosis of the appendix is reported to be just under 1% of the total endometriosis cases[5,6] but because of its propensity to manifest with a wide spectrum of sitespecific presentations, appendiceal endometriosis should be a diagnostic consideration in the evaluation of pre menopausal women with gastrointestinal complaints[7]. This case report presents a lady with vague abdominal pain and ultimately was found to have endometriosis of the appendix at King Khalid University Hospital Riyadh, Kingdom of Saudi Arabia [K.S.A]
