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

Clinical Manifestation of Cytomegalovirus-Associated Protein-Losing Enteropathy in Children

In children, CMV-associated protein-losing enteropathy (PLE) is characterised by a benign course and spontaneous healing but can lead to generalised oedema. Poorly defined, it is diagnosed after unnecessary invasive tests. Children with CMV-associated PLE between 2009 and 2019 in two French hospitals are retrospectively described. Clinical and biological signs, CMV identification, endoscopy and histological findings, disease management and course are analysed. CMV-associated PLE is proven in 21 immunocompetent and 22 immunosuppressed patients, with ages consistent with primo-infection and reactivation, respectively. The digestive symptoms prevail in immunocompetent children, mainly with vomiting (85.7% versus 50%, CI [1.2; 39.2], p = 0.02). Immunocompetent patients show more oedema (61.9% versus 4.5%, CI [3.6; 1502.4], p < 0.001), linked to more severe hypoalbuminemia (21.2 g/L [17.6-25.7] versus 29.6 g/L [24.9-33.9], p = 0.01). A severe course is observed in 23.8% of the immunocompetent patients and 54.5% of the immunosuppressed ones (p = 0.06). Evidence of CMV infection based on non-invasive methods is found on 88.9% of immunocompetent and 95.5% of immunosuppressed patients (p = 0.58), while endoscopy was performed on 95.2% and 100% of them, respectively (p = 0.48), without any therapeutic change. Thus, CMV-associated PLE should be suspected in children with generalised oedema. Not as benign as previously described, it can be confirmed using non-invasive tests.

Ménétrier's disease in a patient with refractory ulcerative colitis: a clinical challenge and review of the literature

Ménétrier's disease (MD) is a rare disease of the stomach, characterised by hypertrophic gastric folds leading to protein loss. The association with ulcerative colitis (UC) is rare but has been reported in the literature. We report a case of a 29-year-old male affected by UC with an additional diagnosis of MD 3 years after UC diagnosis. UC was refractory to several treatment lines (thiopurines, infliximab, vedolizumab and ustekinumab), and the patient underwent colectomy. Octreotide was administered for MD normalising blood biochemistry, but it was not effective in inducing endoscopic remission of the stomach. Treatment options in patients with MD and UC are discussed.

Menetrier’s disease and differential diagnosis: A case report

BACKGROUND

Gastric mucosal hypertrophy, also known as Menetrier's disease (MD), is more common in men over 50 years of age, and the cause is unknown. The symptoms of the disease are atypical, mostly accompanied by hypoproteinemia and edema, and sometimes accompanied by symptoms such as epigastric pain, weight loss, and diarrhea. Most experts believe that the site of the disease is mainly located in the fundus of the stomach and the body of the stomach. We found that the site of the disease in this patient involved the antrum of the stomach.

CASE SUMMARY

We introduced the case of a 24-year-old woman who had repeated vomiting for 5 d and was admitted to our hospital. After various examinations such as computed tomography and pathology in our hospital, the final diagnosis of the presented case is MD. The salient feature is that the mucosal folds in the fundus and body of the stomach are huge and present in the shape of gyrus. The greater curvature is more prominent, and there are multiple erosions or ulcers on the folds. The patient did not undergo gastric surgery and did not undergo re-examination. She is drinking Chinese medicine for treatment, and her vomiting and abdominal pain symptoms have improved. This disease is relatively rare in clinical practice, and it is easy to be misdiagnosed as gastric cancer, chronic gastritis and gastric lymphoma, etc.

CONCLUSION

MD can occur in the antrum, it is necessary to raise awareness of the disease and reduce misdiagnosis.

Menetrier disease and Cytomegalovirus infection in paediatric age: report of three cases and a review of the literature

Paediatric Menetrier disease (PMD) is a protein-losing gastropathy, presenting with generalized oedema and abdominal symptoms. PMD commonly has an acute course and may be associated with Cytomegalovirus (CMV) infection. The aim of this retrospective study is to assess the epidemiological and clinical data, diagnostic procedures, treatment and outcome of CMV-associated PMD. The medical charts of the patients with PMD and CMV infection diagnosed at our hospital have been reviewed. Then, a systematic literature's review of all the cases of PMD and a selection of those associated with CMV infection have been performed. Three previously healthy boys were admitted for vomiting and oedema. Endoscopy showed hypertrophic gastric folds and CMV infection was diagnosed. Albumin was administered in all cases, with clinical resolution within few weeks. In literature, PMD has been described in 150 children and the association between CMV and PMD was found in 89 cases. Clinical and laboratory data, radiological and histological exams, therapy and outcome were reviewed.Conclusions: Basing on the present experience and on the current knowledge, PMD has a benign course without long-term sequelae. Although PMD is rare in children, we recommend paediatricians to consider CMV-related PMD when facing children with vomiting and diffuse oedema. What is Known: • Paediatricians should consider Menetrier disease (MD) when facing oedematous child complaining of abdominal symptoms with hypoalbuminemia, without proteinuria and liver dysfunction. • Typical ultrasound features (hypertrophic gastric folds) suggest such condition which requires endoscopy and biopsy for definitive diagnosis. What is New: • A familial susceptibility to CMV gastric infection has been recently suggested; thus when suspecting MD, the family history of gastric diseases should be investigated. • Menetrier disease has been found associated with other unusual conditions either benign (such as gastric bezoar) or malign as neoplasms (acute lymphatic leukaemia and adenocarcinoma) even in children.

Diagnosis and Management of Ménétrier Disease in Children: A Case Series Review

PURPOSE

Ménétrier disease (MD) was first described in 1888, and 50 cases have been reported until now. We aimed to discuss the etiology, diagnostics, and management of MD in children.

METHODS

We searched for case reports published from 2014 till 2019 in English using PubMed. Articles were selected using subject headings and key words of interest to the topic. Interesting references of the included articles were also included.

RESULTS

The pathophysiology of MD is still uncertain. However, overexpression of transforming growth factor alpha with transformation of the gastric mucosa has been observed, which may be mediated by genetics and provoked by an infectious trigger. Clinically, MD is diagnosed by abdominal pain, vomiting, anorexia, and edema secondary to hypoalbuminemia. A gastroscopy with biopsy is the gold standard for the diagnosis of MD. In children, the disease is self-limiting and only requires supportive treatment. In general, children have a good prognosis and recover spontaneously within a few weeks.

CONCLUSION

Few pediatric cases of MD have been described in recent years, and with all different etiology. Endoscopy with biopsy remains the golden standard for the diagnosis of MD, and in children, the disease is self-limiting.
