INTRODUCTION

A 23-year-old young female patient presenting with persistent diarrhea and eosinophilia, who had clinical improvement after administration of steroids.

A 23-year-old Filipino female, without comorbidities presented with abdominal pain, diarrhea and vomiting. Initial work-up showed peripheral eosinophilia. Computed tomography (CT) of the abdomen revealed massive ascites. An esophagogastroduodenoscopy (EGD) was done which revealed acute duodenitis. Gastric and duodenal biopsy revealed tissue eosinophilia. Total Immunoglobulin E (IgE) was elevated while work-up for intestinal parasitic infection was negative. On bone marrow biopsy, there was no eosinophilic infiltration. Oral prednisone was then started at 60mg/day and was subsequently tapered over 30 days resulting in resolution of symptoms.

This report illustrates a rare case of eosinophilic gastroenteritis (EGE). EGE may mimic a wide spectrum of gastrointestinal disorders, hence, prompt recognition of EGE and awareness of its clinical symptoms, diagnosis and treatment is important.

OBJECTIVE: To evaluate the clinical features, laboratory and imaging results, treatment and outcomes of eosinophilic fasciitis (EF) and assess the value of ultrasound in the diagnosis of EF. METHODS: We retrospectively analyzed the clinical data of 45 patients with EF treated in our center from January 1, 2006 to February 28, 2022. The consistency between the diagnoses of EF based on ultrasound and MRI findings was assessed. RESULTS: In the 45 EF patients (male/female ratio 3.5:1), the age of onset ranged from 16 to 64 years with a mean disease course of 22.6 months. The average time from symptom onset to diagnosis was 16 months. The most common possible trigger of the disease was vigorous exercise (10/45), causing symmetrical lesions in the limbs, most commonly in the forearms (86.7%) and lower legs (80%). Clinical features of EF included subcutaneous swelling and induration (95.6%), arthralgia and arthritis (55.6%), groove sign (42.2%), hand joint contractures (42.2%), skin pigmentation (37.8%), and peau d'orange appearance (13.3%). Eosinophilia was found in 31 patients (68.9%). Hypergammaglobulinemia was seen in 23/44 (52.3%) and positive antinuclear antibodies in 9 (20%) of the patients. Twentyone of the patients were treated with high-dose methylprednisolone (≥200 mg daily for 3 to 5 consecutive days), and compared with the patients who did not receive this treatment, these patients more frequently experienced relapse before admission, had more extensive involvement, and had a higher rate of hypergammaglobulinemia without fever, but these differences were not statistically significant. Of the 31 patients (68.9%) with follow-up data (for a median of 3.2 years [range 0.2-15.9]), complete remission was achieved in 12 (38.7%) patients, and the accumulative complete remission rate was 44.1% at 5.5 years. No specific baseline characteristics or immunosuppressants were found to correlate with the treatment response. A total of 26 patients underwent both ultrasound and MRI examination, and the Kappa value of the diagnostic results between ultrasound and MRI was 0.91. CONCLUSION EF is characterized by symmetrical subcutaneous swelling and induration in the limbs, accompanied by eosinophilia and hypergammaglobulinemia. Glucocorticoid is effective for treating EF. Ultrasound examination can identify thickening of subcutaneous fascia for an early diagnosis of EF.

Chronic rhinosinusitis（CRS） is an inflammatory disease involving the mucosa of the nasal and paranasal sinuses for more than 12 weeks and can be classified as CRS with nasal polyp（CRSwNP） and CRS without nasal polyp（CRSsNP） depending on the phenotype. Clinical treatments reveal significant differences in disease prognosis and improvement in quality of life in patients with the same clinical phenotype. Inflammatory cells infiltration and inflammatory mediators are important factors driving CRS endotypes. In particular, CRS with predominantly eosinophilic infiltration and type 2 CRS present severe clinical symptoms, comorbidities, and high recurrence rates. CRS endotype-oriented treatment methods may better contribute to improving patient prognosis and quality of life. This article summarizes the current progress of CRS endotype research and reviews the endotype-oriented treatment options.

Eosinophilic gastroenteritis (EGE) is a gastrointestinal disorder of unclear etiology that is characterized by eosinophilic infiltration of the stomach and small intestine, and consists of mucosal, muscular, and serosal subtypes. Eosinophilic infiltration of the gastrointestinal tract is a fundamental histopathological characteristic of EGE and is driven by several T-helper type 2 (Th2)-dependent cytokines and induced by food allergy. Due to the lack of a diagnostic gold standard, EGE has a high rate of delayed diagnosis or misdiagnosis. However, several new diagnostic strategies have been developed, such as novel genetic biomarkers and imaging tests. Although dietary therapy and corticosteroids remain the common choices for EGE treatment, recent decades have seen the emergence of novel treatment alternatives, such as biologics that target particular molecules involved in the pathogenic process. Preliminary investigations and clinical trials have demonstrated the efficacy of biologics and provided additional insights for the era of refractory or corticosteroid-dependent EGE biologics.

OBJECTIVE: To investigate the risk factors and prognosis of cardiovascular damage in hypereosinophilia (HE). METHODS: The clinical data of 62 patients with HE in Gansu Provincial Hospital from January 2015 to December 2020 were retrospectively analyzed, including clinical characteristics and laboratory indicators, and the influencing factors of survival and prognosis were also analyzed. RESULTS: In this study, there were 34 males and 28 females, with a median age of 53.5 (20-79) years, 35 patients without cardiovascular damage, 27 patients with cardiovascular damage, including 22 patients with abnormal electrocardiogram (ECG) (81.5%), 18 patients with abnormal echocardiography (ECHO) (66.7%), 9 patients with single ECG abnormality, 5 patients with single ECHO abnormality, and other 13 patients with multiple abnormalities. In cardiovascular damage group, peripheral white blood cell count, absolute value of eosinophils, troponin T (TNT), N-terminal pro-B-type natriuretic peptide (NT-proBNP), interleukin (IL)-4 and IL-5 levels at initial diagnosis were significantly higher than those in the non-cardiovascular damage group (P <0.01), while hemoglobin, IL-2 and interferon-γ levels were significantly lower (P <0.01). There were no significant differences in age, sex, course of disease, etiological classification, platelet count, serum creatine kinase, serum creatine kinase isoenzyme and lactate dehydrogenase between the two groups (P >0.05). The 5-year overal survival rate of patients with cardiovascular damage was 88.9%, and that of patients without cardiovascular damage was 100%, the difference was statistically significant (P =0.012). The 5-year event-free survival (EFS) rate of patients with cardiovascular damage was 59.3%, and the median time was 37 (21-52) months, while that of patients without cardiovascular damage was 80%, and the median time was 63 (51-74) months (P =0.002). Age (>60 years old), course of disease (>24 months), NT-proBNP (>3 000 pg/ml), TNT (>100 ng/L), elevated IL-4 and IL-5 were associated with EFS shortening in patients with cardiovascular damage, which were independent risk factors for EFS. CONCLUSION The EFS rate in HE patients without cardiovascular damage is significantly higher than patients with cardiovascular damage. Age, course of disease, NT-proBNP, TNT, IL-4 and IL-5 are independent risk factors affecting EFS of patients with cardiovascular damage.

OBJECTIVE: To investigate the impact of a history of atopy on the value of fractional exhaled nitric oxide (FENO) for predicting sputum eosinophils in patients with chronic cough. METHODS: A total of 868 patients with persistent cough lasting more than 3 weeks without pulmonary infection were enrolled, including 119 patients with subacute cough (defined as cough lasting 3-8 weeks) and 749 with chronic cough (longer than 8 weeks). The predictive value of FENO level for sputum eosinophilia was analyzed using receiver-operating characteristic (ROC) curve analysis, and the area under the curve (AUC) was calculated. The atopy status of the patients was determined by screening for history of allergy, hay fever, or animal or food allergies. RESULTS: Of the 868 patients enrolled, 173 patients (19.9%) had eosinophilic airway inflammation (EAI). In the overall patients, the median (Q1, Q3) FENO level was 18 (12, 35) ppb, ranging from 5 to 300 ppb. The patients with chronic cough and a positive history of atopy had a higher median FENO level than those without atopy (24 [13, 50] vs 18 [11, 34]; Z=2.25, P= 0.029), and FENO level was significantly correlated with EAI (r=0.281, P < 0.001). The AUCs of FENO for diagnosis of airway eosinophilia in patients with atopy and those without atopy were 0.677 (95% CI: 0.548-0.806) and 0.708 (95% CI: 0.660-0.756), respectively. The optimal cut-off value of FENO for diagnosing EAI was higher in patients with atopy than in those without atopy (72 vs 28.5 ppb). CONCLUSION A history of atopy reduces the predictive value of FENO level for EAI in patients with chronic cough, suggesting the importance of examining the atopic status when interpreting test results of FENO.
