Eosinophilic ascites: an unusual manifestation of eosinophilic gastroenteritis

Successful Introduction of Benralizumab for Eosinophilic Ascites

Eosinophilic ascites is a rare disorder, reported in both adult and pediatric patients, characterized by high eosinophil counts in the peritoneal fluid. Eosinophilic ascites appears as a manifestation of various diseases such as parasitic and fungal infections, malignancy, and hypereosinophilic syndrome. It also represents an uncommon manifestation of eosinophilic gastroenteritis, usually treated with corticosteroids. We present the case of a 16-year-old woman with abdominal distention related to abundant ascites. Further work-up concluded that it was eosinophilic gastroenteritis complicated with eosinophilic ascites. The patient was on oral steroids for three weeks, but various abdominal relapses were observed, leading to the introduction of benralizumab, as a steroid-sparing therapy with a favorable outcome.

Plasma membrane lesion type total intestinal eosinophilic enteritis: A case report

BACKGROUND

Eosinophilic gastroenteritis is a rare gastrointestinal disease that is characterized by diffuse or localized eosinophil infiltration in the gastrointestinal tract, and is accompanied by increased peripheral blood eosinophils. Herein, a case of plasma membrane lesion-type total intestinal eosinophil enteritis is reported.

CASE PRESENTATION

We report on a 20-year-old male patient who was admitted to the hospital with "abdominal distension for 15 days". The infiltration of a large number of eosinophils was found by conducting an intestinal biopsy, routine ascites examination, blood routine, smear test, and a bone marrow puncture. A special feature of this patient was that a large number of eosinophils were found in the duodenum, small intestine, and colon. The final diagnosis was plasma membrane lesion type total intestinal eosinophilic enteritis. After four weeks of prednisone treatment, the symptoms disappeared completely and the entire intestinal mucosa was endoscopically observed as smooth.

CONCLUSION

Clinical practitioners must pay attention to gastrointestinal endoscopy and biopsy pathology results for patients presenting with abdominal distention and ascites. Combined with an abnormal increase of eosinophils in ascites, bone marrow, and peripheral blood, clinical practitioners must be highly vigilant against plasma membrane lesion type total intestinal eosinophilic enteritis.

Eosinophilic ascites as an uncommon presentation of eosinophilic gastroenteritis: A case report

BACKGROUND

Eosinophilic gastroenteritis (EGE) is defined by the presence of gastrointestinal symptoms, with an abnormal eosinophilic infiltrate of the intestine wall and exclusion of other causes of secondary eosinophilia. EGE has three clinical presentations, depending on the depth of eosinophilic infiltration of the bowel wall. It individualizes into three types, namely mucosal, muscular, and subserosal. Eosinophilic ascites, which is caused by edema and eosinophilic inflammation of the serosal layer of the small bowel wall, is the most uncommon presentation of EGE.

CASE SUMMARY

A 30-year-old Egyptian woman presented with pain in the epigastrium and diffuse abdominal distension. Past medical history comprised allergy to iron injections (for iron deficiency anemia). Clinical examination showed moderate abdominal distention (palpation) and shifting dullness (percussion) suggestive of moderate ascites; mild right pleural effusion was also suspected, but findings were otherwise unremarkable. Abdominal and pelvic examinations by ultrasound and contrast-enhanced computed tomography showed moderate ascites, mild right pleural effusion, and diffuse thickening of the antrum and small bowel loops. Endoscopy of the upper gastrointestinal tract revealed mild diffuse hyperemia of the esophagus, stomach and duodenum, with no relevant findings in the histopathology of biopsy specimens taken from these sites. Laboratory results showed eosinophilia in the peripheral blood and marked increase of eosinophils in the ascitic fluid. Treatment with corticosteroids resulted in normalization of the laboratory test results, and the ascites resolved within a week of initiation of therapy.

CONCLUSION

Eosinophilic ascites, characterized by increased eosinophils in peripheral blood and ascitic fluid, showed dramatic response to steroid therapy.
