Non-esophageal eosinophilic gastrointestinal disorder (non-EoE EGID) is a group of immune-mediated gastrointestinal diseases characterized by infiltration of eosinophils. Although most patients experience symptom relief after treatment, some still face the risk of persistent symptoms or relapse. Improving the prognosis for this subset of patients remains an urgent challenge. Identifying risk factors that affect the prognosis of non-EoE EGID and providing timely effective interventions are crucial for improving outcomes. This paper reviews the risk factors related to the prognosis of pediatric non-EoE EGID, including genetic factors, allergies, environmental factors, clinical characteristics, endoscopic findings, and pathological manifestations, with the aim of providing references for clinical decision-making.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare multi-system disease that presents significant diagnostic challenges due to its complexity and low incidence (White and Dubey, 2023). It affects males and females equally, though males may exhibit more active disease at diagnosis and often require more aggressive treatment (Liu et al., 2023). The hallmark features of EGPA include delayed-onset asthma, eosinophilia in tissues and blood, and vasculitis affecting small to medium-sized arteries (White and Dubey, 2023). EGPA falls under the category of antineutrophil cytoplasmic antibody (ANCA)‍-associated vasculitis (AAV), whereas only about half of EGPA patients test positive for ANCA (Khoury et al., 2023).

A boy, aged 17 years, was admitted again due to abdominal pain, diarrhea, and eosinophilia for 3 years, which worsened for 3 days. Three years ago, the boy suffered from abdominal pain and diarrhea after eating yogurt; color Doppler ultrasound showed a large amount of peritoneal effusion, and routine blood test, bone marrow cell morphology, and ascites histological examination showed a large number of eosinophils. Three days ago, he was admitted again due to abdominal pain and diarrhea. The gastrointestinal endoscopy showed eosinophil infiltration in the angle of stomach. The boy was diagnosed with eosinophilic gastrointestinal disease (eosinophilic gastroenteritis). He was improved after the treatment with glucocorticoids and dietary avoidance, and no recurrence was observed during the one-year follow-up. It is concluded that for children who attend the hospital due to gastrointestinal symptoms such as abdominal pain and diarrhea, if there is an increase in peripheral blood eosinophils, it is necessary to consider the possibility of eosinophilic gastrointestinal disease, and eosinophil infiltration and abnormal eosinophil count in gastrointestinal tissue based on endoscopic biopsy may be the key to diagnosis.

Peritoneal dialysis (PD)-related peritonitis is recognized as a common complication of peritoneal dialysis. Eosinophilic peritonitis is a rare type of non-infection PD-related peritonitis. Eosinophilic peritonitis in continuous ambulatory peritoneal dialysis (CAPD) patients was first reported in 1967. The cause of eosinophilic peritonitis is obscure, however it may be related to some etiologies: (1) hypersensitivity to PD materials, including catheter or dialysate; (2) bacteria, fungal or mycobacterium tuberculosis infection. Clinical investigations include asymptomatic cloudy PD effluent, fever, abdominal pain and eosinophil count elevate in PD effluent. Eosinophilic peritonitis is usually mild and self-limited. With the development of PD, more eosinophilic peritonitis cases and researches were reported. Here, we report a patient on CAPD with eosinophilic peritonitis. A 71-year-old female patient developed end-stage renal disease for 4 years and underwent CAPD (2 000 mL of 1.5% dialysis solution with four exchanges daily) for 5 months. With a history of unclean food, she was hospitalized for complaints of diarrhea, fever and cloudy peritoneal effluent for 10 days. Dialysis effluent showed an elevated white blood cell (WBC) count of 1 980 cell/mm³, with 60% polymorphonuclear cells. She was diagnosed as PD-related peritonitis, and therapy was initiated with intraperitoneal ceftazidime 1 g once a day and vancomycin 500 mg every other day. She was admitted to the hospital as the symptoms were not relieved. Her peripheral blood cell count showed a total WBC count of 6 940 cells/mm³, 36.8% eosinophil. Her PD effluent analysis showed turbidity, total WBC count of 1 480 cells/mm³, and 83% polymorphonuclear cells. Her dialysate bacteria culture, fungus culture, polymerase chain reaction for Mycobacterium tuberculosis (TB-PCR), acid-fast stain were all negative. On admission day 4, the treatments were changed to levofloxacin 200 mg once a day and vancomycin 500 mg every other day. After two weeks of antibiotics treatment, patient's symptoms were not completely improved and her dialysis effluent remained cloudy. Her blood eosinophil count elevated to 36.8%，eosinophil proportion in PD effluent>90% and PD effluent pathological findings showed eosinophil>90%. Eosinophilic peritonitis was diagnosed and a decision was made to give loratadine daily dose of 10 mg orally. The possible reasons might be the patient's allergy to some components of PD solution or connection systems in the beginning of PD, and this bacterial peritonitis episode, as well as the application of vancomycin, might lead to the fact that eosinophilic peritonitis acutely developed. For there was no improvement in clinical symptoms, loratadine was stopped, and the patient was discharged 18 days later, and received follow-up closely. Two months later, eosinophil count in blood and PD fluid decreased to normal range with no symptom. This case reminds us that in any PD-related peritonitis patient with prolonged symptoms after appropriate antibiotic therapy, and typical clinical symptoms, the diagnosis of eosinophilic peritonitis should be considered. For the count and percentage of eosinophils are not routinely reported in most laboratories, doctors need to contact the department of laboratory and the department of pathology, to confirm the cell count and proportion of eosinophils in dialysis effluent, so as to make the definite diagnosis, which can not only avoid antibiotics overuse, but also avoid antibiotics-induced eosinophilic peritonitis (such as vancomycin).

BACKGROUNDDrug reaction with eosinophilia and systemic symptoms (DRESS) is a severe, life-threatening disorder caused by drugs. In the present study, we tried to explore the types of DRESS-inducing drugs, incubation period, features of skin rashes, accompanying visceral damage, and effectiveness of glucocorticoid therapy so as to inform clinical practice.

METHODSPatients diagnosed with a drug-induced rash, dermatitis, and DRESS admitted to our hospital from January 2006 to December 2015 were included in the study. The diagnosis followed the criteria and scoring system set by the European Registry of Severe Cutaneous Adverse Reactions. Statistical analyses were carried out using SPSS version 17.0 (IBM, Armonk, NY, USA), and a value of P < 0.05 was considered statistically significant.

RESULTSAmong 104 patients, 38 were male and 66 female (aged 18-83 years). The latent period was 13 (interquartile range [IQR]: 10-17) days. The most common allergy-inducing drugs were antibiotics (n = 37, 35.6%), followed by antiepileptic drugs and traditional Chinese medicines (TCMs). Eighty-two cases (78.8%) had rash with area >50% body surface area (BSA). Liver damage occurred in 90% of cases. Patients were divided into oral antihistamine group and glucocorticoid/immunosuppressive agent/intravenous immunoglobulin (IVIG) group. Sex, age, incubation period, duration of hospital stay, and the number of patients with body temperature ≥38.5°C were not significantly different between the two groups. However, the number of patients meeting the criteria of "definite" and "probable" (χ2 = 5.852, P = 0.016), with an eosinophilic granulocyte count of ≥1.5 × 109/L (χ2 = 7.129, P = 0.008), and with rash area of >50% BSA (χ2 = 4.750, P = 0.029), was significantly different.

CONCLUSIONSAntibiotics were associated with allergic reactions, but TCMs also had an important role. Allergy resulting from repeat use of the same drug was more severe with a shorter incubation period. The most typical rash was widespread erythematous papules. Liver damage accounted for >90% of cases.

A 2-year-old boy was admitted into the hospital because of cough and fever. Lymph node tuberculosis was noted when he was 2 months old and he was subsequently hospitalized several times because of cough and fever. After hospitalization the laboratory examination showed an increased eosinophia level in blood. The immune function tests shows decreased levels of IgG, IgA, and IgM. The patient had no response to anti-tuberculosis, anti-bacterial, and anti-fungal treatment, resulting in recurrent fever and progressive enlargement of the liver and spleen. Jam-like stools were noted 35 days after admission. B ultrasonography showed suspected intussusception. Laparotomy, reduction of intussusception and ileocecum angioplasty, biopsies of intestinal wall nodules and lymphoglandulae mesentericae, and hepatic biopsy were then performed under general anesthesia. The patient eventually died because of postoperative severe liver damage, disseminated intravascular coagulation and electrolyte disorder. Both the blood culture and hepatic biopsy tests showed Penicillium marneffei infecton. Immunodeficiency gene test was performed on the patient, his bother and their parents. T→G base substitution mutation (IVS1-3 T→G) in the CD40L gene was found in the patient. X-linked hyper-IgM syndrome was thus diagnosed in the patient. His mother was a carrier of the mutated CD40L gene, but his father was normal in the gene test. Hemizygous mutation in the CD40L gene was found in both the patient and his bother.

Acute eosinophilic pneumonia (AEP) is an uncommon inflammatory lung disease, and limited data exist concerning the clinical characteristics and factors that influence its occurrence. We retrospectively reviewed the records of AEP patients treated at Korean military hospitals between January 2007 and December 2013. In total, 333 patients were identified; their median age was 22 years, and all were men. All patients presented with acute respiratory symptoms (cough, sputum, dyspnea, or fever) and had elevated levels of inflammatory markers including median values of 13,185/microL for white blood cell count and 9.51 mg/dL for C-reactive protein. All patients showed diffuse ground glass opacity/consolidation, and most had pleural effusion (n = 265; 80%) or interlobular septal thickening (n = 265; 85%) on chest computed tomography. Most patients had normal body mass index (n = 255; 77%), and only 30 (9%) patients had underlying diseases including rhinitis, asthma, or atopic dermatitis. Most patients had recently changed smoking habits (n = 288; 87%) and were Army personnel (n = 297; 89%).The AEP incidence was higher in the Army group compared to the Navy or Air Force group for every year (P = 0.002). Both the number of patients and patients with high illness severity (oxygen requirement, intensive care unit admission, and pneumonia severity score class > or = III) tended to increase as seasonal temperatures rose. We describe the clinical characteristics of AEP and demonstrate that AEP patients have recently changed smoking habits and work for the Army. There is an increasing tendency in the numbers of patients and those with higher AEP severity with rising seasonal temperatures.

Eosinophilic gastroenteritis (EGE) is a rare disease characterized by focal or diffuse eosinophilic infiltration of the gastrointestinal tract, especially the stomach and duodenum. EGE has vague, nonspecific symptoms, including nausea, vomiting, abdominal pain, diarrhea, weight loss, ascites, and malabsorption. Here, we report a patient with EGE presenting with concurrent acute pancreatitis and ascites. A 68-year-old woman was admitted with abdominal pain, nausea, vomiting, and watery diarrhea. Laboratory findings revealed elevated serum titers of amylase, lipase, and peripheral blood eosinophil count. An abdominopelvic computed tomography scan showed a normal pancreas, moderate amount of ascites, and duodenal thickening. A esophagogastroduodenoscopy showed patchy erythematous mucosal lesions in the 2nd portion of the duodenum. Biopsies from the duodenum indicated eosinophilic infiltration in the lamina propria. The patient was successfully treated with prednisolone and montelukast. Despite its unusual occurrence, EGE may be considered in the differential diagnosis of unexplained acute pancreatitis, especially in a patient with duodenal edema on imaging or peripheral eosinophilia.

Sparganosis is a rare parasitic disease caused by migrating plerocercoid tapeworm larva of the genus Spirometra. Infection in humans is mainly caused by the ingestion of raw or inadequately cooked flesh of infected frogs, snakes, and chickens. Here, we report a rare case of a 45-year-old man who was admitted to our hospital with left lower chest pain. The chest radiograph and computed tomography (CT) scan revealed localized pleural effusion in the left lower lobe; further, peripheral blood eosinophilia and eosinophilic pleural effusion were present. Percutaneous catheter drainage was performed, which revealed long worm-shaped material that was identified as a sparganum by DNA sequencing. The patient showed clinical improvement after drainage of the sparganum. This study demonstrates the importance of considering parasitic diseases in the differential diagnosis of eosinophilic pleural effusion.
