Síndrome Edematoso Generalizado por citomegalovirus

El síndrome edematoso generalizado o anasarca está presente secundario a un desequilibrio de la homeostasis hídrica, electrolítica y osmolar del organismo, En el adulto el estado de anasarca es más frecuente secundario a insuficiencia cardiaca, en pediatría, el edema que se generaliza está asociado con más frecuencia a bajo aporte proteico, baja síntesis de proteínas o debido a perdida de proteínas de origen gastrointestinal o renal. La disminución de la presión oncótica plasmática genera fuga de líquidos a compartimientos intersticiales de forma generalizada y produce edema. Existen múltiples patologías y mecanismos para la producción del edema generalizado; el conocimiento de la fisiopatología de su desarrollo permite un análisis clínico, de laboratorio y de gabinete que orientan al diagnostico. La infección por citomegalovirus es una causa poco frecuente de edema generalizado, reconocer esta entidad y llegar a un adecuado diagnóstico diferencial es el objetivo de esta revisión.

The generalized edematous syndrome or anasarca is present secondary to an imbalance in the body's water, electrolyte and osmolar homeostasis. In adults, the state of anasarca is more frequent secondary to heart failure; in pediatrics, generalized edema is associated with more frequency due to low protein intake, low protein synthesis or due to protein loss of gastrointestinal or renal origin. The decrease in plasma oncotic pressure generates generalized fluid leakage into interstitial compartments and produces edema. There are multiple pathologies and mechanisms for the production of generalized edema; knowledge of the pathophysiology of its development allows a clinical, laboratory and office analysis that guides the diagnosis. Cytomegalovirus infection is a rare cause of generalized edema; recognizing this entity and reaching an appropriate differential diagnosis is the objective of this review.

Menetrier's disease. A diagnostic and therapeutic challenge / Enfermedad de Menetrier. Un desafío diagnóstico y terapéutico

Abstract We present a rare case of hypertrophic gastropathy associated with protein loss. A 35-year-old man was hospitalized for bowel habit changes, abdominal pain, generalized edema and symptomatic anemia. Pertinent laboratory findings included iron deficiency anemia (Hb 6.7g/dl, ferritin 5 ng/ml) and marked hypoalbuminemia (albumin 2.5 g/dl). Endoscopic biopsy samples of giant gastric folds observed along the greater gastric curvature revealed foveolar hyperplasia and significant parietal cell loss. Endoscopic ultrasonography showed gastric parietal thickening with preserved architecture and normal gastric wall layers. Menetrier disease was diagnosed and the patient treated with cetuximab, a monoclonal antibody that inhibits ligand binding of trans forming growth factor alpha (TGFa), preventing gastric mucosa cell proliferation. After twelve months of treatment, the patient referred symptoms improvement, and gastric biopsy levels of the proliferation marker protein Ki-67 had decreased.

Resumen Presentamos un caso infrecuente de gastropatía hipertrófica asociada a pérdida de proteínas. Un hombre de 35 años fue hos pitalizado por cambios en los hábitos intestinales, dolor abdominal, edema generalizado y anemia sintomática. Los hallazgos de laboratorio pertinentes incluyeron anemia ferropénica (Hb 6.7 g/dl, ferritina 5 ng/ml) e hipoal buminemia marcada (albúmina 2.5 g/dl). Las muestras de biopsia endoscópica de pliegues gástricos gigantes observados a lo largo de la curvatura mayor gástrica revelaron hiperplasia foveolar y pérdida significativa de células parietales. La ecografía endoscópica mostró engrosamiento parietal gástrico con arquitectura conservada y capas de pared gástrica normales. Se diagnosticó enfermedad de Menetrier y se trató al paciente con cetuximab, un anticuerpo monoclonal que inhibe la unión del ligando del factor de crecimiento transformante alfa (TGFa), evitando la proliferación de células de la mucosa gástrica. Después de doce meses de tratamiento, el paciente refirió mejoría de los síntomas y los niveles de la proteína marcadora de proliferación Ki-67 en biopsia gástrica habían disminuido.

Infección por citomegalovirus y Helicobacter pylori, en un niño con enfermedad de Ménétrier / Citomegalovirus and Helicobacter pylori infection in a child with Ménétrier´s disease

Resumen La enfermedad de Ménétrier es una entidad clínica rara, de etiología no clara, caracterizada por hiperplasia foveolar gástrica asociada con pérdida secundaria de proteínas. En niños se presenta con edema, que puede ser generalizado, sin compromiso renal ni hepático y difiere de la forma adulta por la persistencia del edema y la remisión espontánea. En la mayoría de casos publicados, se relaciona con infecciones, usualmente por cytomegalovirus y Helicobacter pylori. Aquí se presenta el caso de un niño de 9 años, que consulta por un mes de evolución de edema y dolor abdominal. Al examen físico se documenta anasarca, y estudios de laboratorio revelaron hipoalbuminemia sin proteinuria.

Abstract Ménétrier disease is a rare disorder characterized by gastric foveolar hyperplasia associated with secondary protein loss. In children, this condition presents as an edematous syndrome without renal or hepatic impairment and differs from the adult form by the constant presence of edema and spontaneous remission. It has been related to infections in most published cases, especially to cytomegalovirus and Helicobacter pylori. Here we analyze the case of a 9 year old boy, complaining of one month of edema and abdominal pain. Physical exam revealed a patient with anasarca and laboratory results documented hypoalbumenemia without proteinuria.

Enfermedad de Ménétrier en pacientes pediátricos secundaria a una infección por citomegalovirus: Presentación de dos casos clínicos en un centro de alta complejidad / Ménétrier's disease in pediatric patients secondary to cytomegalovirus infection: Presentation of two clinical cases in a high complexity center

La enfermedad de Ménétrier es una gastroenteropatía perdedora de proteínas. Definida como una entidad rara y de causa desconocida, la mayoría de los casos reportados la han asociado a infecciones virales. En los pacientes pediátricos, presenta un comienzo agudo con un curso benigno y autolimitado. Se caracteriza por tener pliegues gástricos engrosados que, generalmente, involucran el cuerpo y el fundus gástrico, asociados a hipoalbuminemia, debido a la pérdida de proteína sérica a través de la mucosa. A continuación, se exponen dos casos clínicos de síndrome de Ménétrier infantil asociado a infección por citomegalovirus.

Ménétrier's disease is a protein losing gastroenteropathy. Defined as a rare entity with an unknown cause, most of the reported cases have been associated with viral infections. In pediatric patients, it is characterized by an acute onset with a benign and self-limiting course. It is characterized by thickened gastric folds that generally involve the body and the gastric fundus, associated with hypoalbuminemia due to the loss of serum protein through the mucosa. The following are two clinical cases of infant Ménétrier syndrome associated with cytomegalovirus infection.

Enfermedad de Ménétrier en niños: reporte de dos casos / Two cases of Menétrier's disease in children

Ménétrier’s Disease as a Gastrointestinal Manifestation of Active Cytomegalovirus Infection in a 22-Month-Old Boy: A Case Report with a Review of the Literature of Korean Pediatric Cases

Ménétrier’s disease (MD), which is characterized by hypertrophic gastric folds and foveolar cell hyperplasia, is the most common gastrointestinal (GI) cause of protein-losing enteropathy (PLE). The clinical course of MD in childhood differs from that in adults and has often been reported to be associated with cytomegalovirus (CMV) infection. We present a case of a previously healthy 22-month-old boy presenting with PLE, who was initially suspected to have an eosinophilic GI disorder. However, he was eventually confirmed, by detection of CMV DNA using polymerase chain reaction (PCR) with gastric tissue, to have MD associated with an active CMV infection. We suggest that endoscopic and pathological evaluation is necessary for the differential diagnosis of MD. In addition, CMV DNA detection using PCR analysis of biopsy tissue is recommended to confirm the etiologic agent of MD regardless of the patient’s age or immune status.

Severe hypoproteinemia as a harbinger of Ménétrier's disease in autoimmune pancreatitis / Hipoproteinemia grave como indicador de doença de Ménétrier na pancreatite autoimune

Summary Ménétrier's disease is an extremely rare disease of unknown etiology causing gastric mucosal hypertrophy and protein-losing gastropathy. Rare cases of this condition have been reported in patients with autoimmune diseases. However, to the best of our knowledge, Ménétrier's disease associated with autoimmune pancreatitis (AIP) has never been reported. We described a case of severe hypoproteinemia as a harbinger of Ménétrier's disease associated with AIP. The patient was successfully treated with octreotide and high-protein diet, which led to symptomatic remission and significant improvement in serum levels of albumin and recovery of the nutritional status. Thus, in AIP patients presenting with severe and persistent hypoproteinemia without apparent cause, clinicians need to consider Ménétrier's disease in the differential diagnosis. In this setting, endoscopic evaluation with histological examination of gastric biopsy material, including a full-thickness mucosal biopsy of involved mucosa, may be helpful in promptly establishing the diagnosis and allowing appropriate and timely therapy.

Resumo A doença de Ménétrier é uma condição extremamente rara, de etiologia desconhecida, caracterizada por hipertrofia da mucosa gástrica e gastropatia perdedora de proteína. Casos raros dessa patologia têm sido relatados em pacientes com doenças autoimunes. Até o momento, desconhecemos qualquer relato dessa doença associada à pancreatite autoimune (PAI). Descrevemos um caso de hipoproteinemia grave como indicador de doença de Ménétrier associada à PAI. O paciente foi tratado de forma satisfatória com octreotide e dieta hiperproteica, alcançando remissão sintomática, melhora significativa das concentrações de albumina e recuperação do estado nutricional. Portanto, em pacientes com PAI e hipoproteinemia grave e persistente, deve-se considerar a doença de Ménétrier como um diagnóstico diferencial. Nesses casos, a avaliação endoscópica com biópsia gástrica, incluindo biópsia de toda a espessura da mucosa, pode ser útil no estabelecimento do diagnóstico e do pronto início da terapêutica.

Menetrier's Disease: Its Mimickers and Pathogenesis

Menetrier's disease is a rare protein-losing hypertrophic gastropathy. Histologically, it can be mistaken for other disorders showing hypertrophic gastropathy. The pathogenesis of Menetrier's disease is not fully understood; however, it appears that the epidermal growth factor receptor (EGFR) ligand, transforming growth factor alpha, contributes to the pathogenesis of this disorder. In this review, we will discuss disease entities that can mimic Menetrier's disease and the role of EGFR signaling in Menetrier's disease.

Gastropatía hipertrófica perdedora de proteínas: enfermedad de Ménétrier: caso clínico / Hypertrophic protein-losing gastropathy: Ménétrier disease: a clinical case

Introduction: Ménétrier disease is a rare disorder characterized by gastric foveolar hyperplasia associated with secondary protein loss. In children, this condition is presented as an edematous syndrome without renal or hepatic impairment and differs from the adult form by the constant presence of edema and spontaneous remission. It has been related to infections in most published cases, especially to Cytomegalovirus (CMV) and Helicobacter pylori (H. pylori). Objective: To present a pediatric case of Ménétrier disease and endoscopic imaging obtained during the evolution of the patient. Case report: A five year old preschooler who presented a generalized edema, abdominal pain and malaise. After ruling out renal and hepatic pathologies, an upper endoscopy revealed a severe compromise of the gastric mucosa. Urease test for H. pylori and IgG test for CMV resulted positive. Albumin and H2 receptor antagonists were administered. The evolution was favorable and the patient was discharged after 14 days; 8 month follow-up endoscopy showed no abnormalities. Conclusion: The medical profile and endoscopy are enough evidence to suggest the diagnosis of hypertrophic protein-losing gastropathy. Further studies need to be developed that include a considerable number of patients to assess their association with CMV or H. pylori infections, as these viruses are very common in our population.

Introducción: La enfermedad de Ménétrier es una entidad clínica rara, de etiología desconocida, que se caracteriza por hiperplasia foveolar gástrica asociada a pérdida secundaria de proteínas. En niños, se presenta como un síndrome edematoso sin compromiso renal ni hepático y difiere de la forma adulta por la presencia constante de edema y la remisión espontánea En la mayoría de los casos publicados se la relaciona a infecciones, en especial a Cytomegalovirus (CMV) y Helicobacter pylori (Hp). Objetivo: Presentar un caso pediátrico de Enfermedad de Ménétrier y las imágenes endoscópicas que se obtuvieron durante su evolución. Caso clínico: Preescolar de 5 años que consultó por edema generalizado, dolor abdominal y compromiso del estado general. Habiéndose descartado patología renal y hepática se solicitó una endoscopía digestiva alta que reveló un severo compromiso de la mucosa gástrica. Test de ureasa para Hp e IgG para CMV positivos. Se administró albúmina y antagonistas de receptores H2. La evolución fue favorable con alta al día 14 y endoscopía normal a los 8 meses de seguimiento. Conclusión: El cuadro clínico y la endoscopía son suficientes para plantear el diagnóstico de "Gastropatía hipertrófica perdedora de proteínas". Es necesario desarrollar estudios con un número considerable de pacientes para evaluar su asociación con infección por CMV o Hp, considerando además que estas infecciones son muy frecuentes en nuestra población.

A Case of Pediatric Menetrier's Disease Associated with Helicobacter pylori Infection

Menetrier's disease in childhood is a rare form of gastropathy characterized by hypoalbuminemia, endoscopic and/or radiologic findings of hypertrophic gastric folds, and histologic findings of foveolar hyperplasia in the stomach. It tends to have a self-limited course compared to the chronic and complicated course in adult Menetrier's disease. A 7-year-old boy was referred to Incheon St. Mary's Hospital for facial edema. Physical examination on admission showed periorbital swelling, pitting edema in both legs, and epigastric tenderness. Laboratory tests on admission indicated hypoproteinemia (3.0 g/dL) with hypoalbuminemia (2.1 g/dL) and hypogammaglobulinemia. Urinalysis showed no abnormalities. The test results for anti-cytomegalovirus immunoglobulin M and cytomegalovirus PCR were negative. Stool Helicobacter pylori antigen was positive and fecal alpha1-antitrypsin clearance was 40.1 mL/day, consistent with protein-losing gastroenteropathy. Gastroduodenoscopy showed hypertrophic edematous gastric folds, erythema, and superficial erosion in the body of the stomach. The duodenum was normal. Histologic findings showed foveolar hyperplasia. His symptoms improved with conservative treatment including proton pump inhibitor from day 9 of hospitalization and resolved completely. Here we reported a case of pediatric protein-losing hypertrophic gastropathy associated with Helicobacter pylori infection.

Gastroenteropatía perdedora de proteínas y posible relación con una infección por citomegalovirus: Presentación de un caso de enfermedad de Ménétrier infantil / Protein losing gastroenteropathy and possible relationship to cytomegalovirus infection: Ménétrier disease in a child

La enfermedad de Ménétrier infantil es una gastroenteropatía perdedora de proteínas caracterizada por hipertrofa de la mucosa gástrica, de causa desconocida, aunque la mayoría de los casos informados se han asociado a infecciones virales. Se manifesta clínicamente por edema y bioquímicamente por hipoproteinemia e hipoalbuminemia. Es poco común en los niños, en quienes tiene un carácter benigno y autolimitado, a diferencia de los adultos, en los que tiende a cronifcarse y, en ocasiones, a malignizarse. Se presenta un caso de enfermedad de Ménétrier infantil con síndrome ascítico edematoso posiblemente asociado a una infección por citomegalovirus.

Ménétrier's disease is a childhood protein-losing gastroenteropathy characterized by hypertrophy of the gastric mucosa, of unknown etiology, although most of reported cases have been associated with viral infections. Clinical manifestation is edema and biochemically there are hypoproteinemia and hypoalbuminemia. This disease is very rare in children and they have a benign and self-limiting course in contrast to adults where tend to be chronic and occasionally to become malignant. We present a child with Ménétrier disease with edema and ascites possibly associated with a cytomegalovirus infection.

Co-Infection with Cytomegalovirus and Helicobacter pylori in a Child with Menetrier's Disease / 대한소아소화기영양학회지

Menetrier's disease is a rare protein-losing gastropathy characterized by hypertrophic gastric fold, foveolar hyperplasia, and hypoproteinemia with resulting peripheral edema. It is clinically evident as nonspecific gastrointestinal symptoms, including abdominal discomfort, nausea and vomiting, abdominal pain, weight loss, diarrhea, and edema. Pediatric Menetrier's disease usually has an insidious onset and progressive, chronic clinical course and it spontaneously resolves in weeks or months. The pathogenesis of Menetrier's disease is not clearly understood. Menetrier's disease is thought to be associated with some gastric infections. But the cause of Menetrier's disease is unknown, an association with cytomegalovirus (CMV) and Helicobacter pylori has been suggested. In Korea, We present the first a case of pediatric Menetrier's disease with positive evidence of CMV and H. pylori.

Enfermedad de Ménétrier con compromiso gástrico difuso y duodenal: Caso clínico / Ménétrier disease: Report of one case

Background: Ménétrier disease is a rare disorder of the stomach, characterized by giant hypertrophic folds that usually involve the gastric body and fundus, associated to hypoalbuminemia due to serum protein loss across the gastric mucosa. We report a 55-years-old male presenting with abdominal pain, vomiting, weight loss and hypoalbuminemia. Diffuse hypertrophic gastric folds, elevated ulcerated sessile lesions and focal duodenal involvement were seen at endoscopy. Biopsies showed foveolar hyperplasia and glandular atrophy with cystic dilatation. A total gastrectomy was performed with a good outcome.

A case of cytomegalovirus-negative Menetrier's disease with eosinophilia in a child / 소아과

Menetrier's disease is a rare form of acquired gastropathy characterized by giant rugal folds in the stomach and protein-losing gastropathy. Children with Menetrier's disease tend to follow a benign self-limited course with symptoms typically completely resolving within 2 to 10 weeks in contrast to the chronic course in adults. A 9-year-old girl presented with a history of gradually worsening abdominal distension, increasing body weight, and abdominal pain for 2 weeks. Physical examination on admission indicated periorbital swelling, pitting edema in both the legs, and abdominal distension with mild diffuse tenderness and shifting dullness. Laboratory tests on admission showed hypoalbuminemia, hypoproteinemia, and peripheral eosinophilia. The test result for anticytomegalovirus immunoglobulin M was negative. Increased fecal alpha 1 anti-trypsin excretion was observed. Radiological findings showed massive ascites and pleural effusion in both the lungs. On gastroscopy, large gastric folds, erythema, erosion, and exudation were noted in the body and fundus of the stomach. Microscopic findings showed infiltration of eosinophils and neutrophils in the gastric mucosa. Her symptoms improved with conservative treatment from day 7 of hospitalization and resolved completely.

A Case of Menetrier's Disease Showing Mucus Bridge Observed during Endoscopy / 대한소화기학회지

Menetrier's disease is a rare entity characterized by large, tortuous gastric mucosal folds. The mucosal folds in Menetrier's disease are often most prominent in the body and fundus. Histologically, massive foveolar hyperplasia (hyperplasia of surface and glandular mucous cells) is noted, which replaces most of the chief and parietal cells. Profuse mucus is usually observed during the endoscopy but there have been few cases that show interesting endoscopic findings such as mucus bridge or water pearl. Herein, we report a case of Menetrier's disease showing mucus bridge by excessive mucus observed during the endoscopy.

A case of improved Menetrier's disease after the eradication of Helicobacter pylori and treatment with a proton pump inhibitor / 대한내과학회지

Menetrier's disease is a protein-losing hypertrophic gastropathy characterized by diffuse tremendous thickening of the gastric wall caused by excessive proliferation of the mucosa. Although the cause of Menetrier's disease is unknown, an association with Helicobacter pylori has been reported. A 42-year-old man was hospitalized for the evaluation of progressive body weight loss and indigestion for 6 months, with recently aggravated epigastric discomfort. Gastroscopy revealed prominent mucosal folds in the body and fundus. The histological findings revealed gastritis with erosions and foveolar hyperplasia. After eradicating the Helicobacter pylori and treatment with a proton pump inhibitor, clinical and endoscopic resolution ensued.
