En el análisis de los datos de laboratorio paralelamente destaca la presencia de hipereosinofilia. Las imágenes obtenidas en el estudio de la video cápsula muestran varios geoparásitos de tipo helmintos. Posterior al tratamiento antiparasitario mejora la anemia y se normaliza el recuento absoluto de eosinófilos.

Risk Factors and Prognosis of Cardiovascular Damage in Hypereosinophilia / 中国实验血液学杂志

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.

Research progress on the relationship between hypereosinophilia and ischemic stroke / 中华神经科杂志

Hypereosinophilia (HE) is a kind of hematology disorder affecting multiple organs. Multiple studies demonstrated that HE was correlated with ischemic stroke, and it could be a rare and reversible cause for ischemic stroke. Therefore, more and more concerns have been concentrated by neurologists in recent years. Based on the research data, the definition, typical characteristics, possible mechanism, diagnosis and treatment principles of HE related ischemic stroke were summarized systematically, in order to provide possible personalized treatment strategies for this disease.

Síndrome de larva migrans visceral y absceso hepático: Reporte de un caso / Visceral larva migrans syndrome and hepatic abscess: A case report

La infección por T oxocara canis o catis es una zoonosis diseminada en el ser humano. La toxocariasis puede coexistir con otras parasitosis endémicas. El hombre actúa como huésped no natural y adquiere la infección a través de la ingesta de huevos del geohelminto. Estos pueden localizarse en la tierra, los patios y los juegos de los niños, y son eliminados, principalmente, por perros o gatos. Existen distintos espectros en la presentación clínica; algunos de ellos son toxocariasis ocular, larva migrans visceral, toxocariasis encubierta y neurotoxocariasis. Se presenta el caso de un paciente de 2 años y 3 meses de edad, con antecedente de síntomas respiratorios, fiebre prolongada y hepatomegalia, con resultados de laboratorio que informa hipereosinofilia, hipergammaglobulinemia y serología positiva para toxocariasis (ensayo por inmunoabsorción ligado a enzimas). Se plantea el diagnóstico de síndrome de larva migrans visceral.

Toxocariasis canis or catis is a zoonotic infection disseminated in humans. Human beings can act as non-natural hosts in which the parasite can survive for long periods of time and they become infected by the ingestion of geohelminth eggs. These can be located on the ground, playgrounds and children's games, and are mostly eliminated by dogs or cats. There are different spectra in the clinical presentation of this infection, which can vary from an asymptomatic host to the production of serious organic lesions; some of them are ocular toxocariasis, visceral larva migrans, covert toxocariasis and neurotoxocariasis. In this case report a patient who presents with a history of respiratory problems, prolonged fever, and hepatomegaly. Laboratory analyses show hypereosinophilia, hypergammaglobulinemia and serodiagnosis is positive for toxocariasis. Preliminary diagnosis: Visceral Larva Migrans Syndrome.

Anaplastic Large Cell Lymphoma with Massive Eosinophilia and Complex Karyotype Initially Misdiagnosed as Chronic Eosinophilic Leukemia

We report a patient with massive eosinophilia and a complex karyotype that was initially misdiagnosed as chronic eosinophilic leukemia (CEL), but later diagnosed as anaplastic large cell lymphoma (ALCL) masked by massive eosinophilia. The complex karyotype observed at initial diagnosis remained unchanged later, after the evidence of bone marrow involvement of ALCL was obtained. At diagnosis, genetic aberrations corresponding to metaphase cytogenetics were not identified by interphase fluorescence in situ hybridization, although abnormal results were noted at follow-up. Together, these observations indicate that the complex karyotype at initial work-up has been derived from a low proportion of lymphoma cells with high mitotic ability that were not identified by microscopy, rather than from massive eosinophils. These findings suggest that our patient had ALCL with secondary eosinophilia rather than CEL since initial diagnosis.

Bullous Pemphigoid Associated with Cerebral Infarction: Hypereosinophilia as a Possible Mechanism

Bullous pemphigoid (BP) is an autoimmune skin disease, which manifests as subepidermal blisters with severe itching. BP has been reported to be associated with a higher prevalence of cerebrovascular diseases in population-based studies. However, the mechanism of cerebral infarction from BP has not been elucidated yet. We hereby suggest that the missing link between BP and cerebral infarction may be eosinophil, through a case of a woman with multifocal embolic infarction.

Sulfasalazine Induced DRESS Syndrome: A Review of Case Reports.

Introduction: Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) is designated as a lethal adverse drug effect with characteristic sign and symptoms such as skin rashes, fever, leukocytosis with eosinophilia or atypical lymphocytes, lymph node enlargement, and liver or renal dysfunction. Incidences of the DRESS range from 1/1000-1/10,000 drug exposures and are associated with a mortality rate of 10%. Pathogenesis of DRESS relates to an abnormal immune response in a genetically vulnerable individual, i.e. presence of human leukocyte antigen (HLA)*5801 and HLA-B* 5701 genotype and slow acetylation metabolic pathways. Methods: 48 cases were associated with the “Sulfasalazine-induced DRESS syndrome” reported between January 1990- March 2015 in PubMed-MEDLINE and HighWire Press. The “RegiSCAR” scoring system was used to analyze the case reports. Using this system, cases were classified into 4 categories as “no”, “possible, “probable” and “definite”. Results: The vast majority of cases were classified as “probable/definite” DRESS cases (83%). Hypereosinophilia, atypical lymphocytes and fever were significantly associated with “probable/ definite” DRESS cases. Liver involvement and skin rash was described in almost all of the cases, including “possible cases”. DRESS was found fatal in two cases. Conclusion: Awareness of DRESS is essential for diagnosis with the presence of skin rash, liver involvement, fever, hyper eosinophilia and lymphadenopathy. Early identification, followed by a prompt withdrawal of the culprit drug is the most essential measure to avoid disease evolution and to restore wellness.

A Case of Toxocariasis in a Patient with Cecal Cancer Mimicking Hepatic Metastasis / 대한내과학회지

Toxocariasis is a common helminth infection and the most common cause of peripheral blood eosinophilia. The clinical presentation of liver toxocariasis is often confused with primary or metastatic hepatic tumors. Here, we report on a 52-year-old man admitted with cecal cancer and eosinophilia. Computerized tomography (CT) scans revealed multiple lesions with peripheral enhancement in the liver, and T1- and T2-weighted images revealed isointensity. The patient underwent right hemicolectomy and an exploratory laparotomy with a liver biopsy. Resection of the cecal specimen revealed an adenocarcinoma, while the liver biopsy revealed an eosinophilic abscess with no evidence of malignancy. A serologic test showed a marked increase in specific immunoglobulin G antibody concentrations against Toxocara canis and daily antiparasitic treatment with albendazole (800 mg per day for 7 days) was initiated. Follow-up CT scans indicated that all liver masses and eosinophilia were resolved.

A Case of Hypereosinophilic Syndrome with Bladder Involvement in a 7-Year-Old Boy

Hypereosinophilic syndrome (HES) is characterized by the presense of hypereosinophilia with evidence of target organ damage. We report a patient diagnosed with eosinophilic cystitis and HES. A 7 year old boy had hematuria, dysuria, and increased urinary frequency for 1 day. Laboratory examinations revealed hypereosinophilia (eosinophils, 2,058/microL), hematuria, and proteinuria. Abdominal sonography revealed diffuse and severe wall thickening of the bladder. The patient was treated initially with antibiotics. However, his symptoms did not improve after 7 days. A computed tomography scan demonstrated severe wall thickening of the bladder and the hypereosinophilia persisted (eosinophils, 2,985/microL). The patient complained of chest discomfort, dyspnea, epigastric pain, and vomiting on hospital day 10. Parasitic, allergic, malignancy, rheumatologic, and immune workups revealed no abnormal findings. Chest X-rays, electrocardiography, and a pulmonary function test were normal; however, the hypereosinophilia was aggravated (eosinophils, 3,934/microL). Oral deflazacort was administered. A cystoscopic biopsy showed chronic inflammation with eosinophilic infiltration. The patient's respiratory, gastrointestinal, and urinary symptoms improved after 6 days of steroids, and he was discharged. The eosinophil count decreased dramatically (182/microL). The hypereosinophilia waxed and waned for 7 months, and the oral steroids were tapered and stopped. This case describes a patient diagnosed with eosinophilic cystitis and HES.

Infarto agudo do miocárdio como apresentação inicial de granulomatose eosinofílica com poliangiite (anteriormente, síndrome de Churg Strauss) / Acute myocardial infarction as Eosinophilic granulomatosis with polyangiitis (formerly Churg Strauss syndrome) initial presentation

A granulomatose eosinofílica com poliangiite é uma vasculite primária rara, caracterizada por hipereosinofilia, asma de surgimento tardio e granulomas eosinofílicos extravasculares. Relatamos um caso apresentado inicialmente com infarto do miocárdio e que, ulteriormente, teve prosseguimento apenas com asma, manifestações cutâneas e neuropatia periférica. Os parâmetros laboratoriais revelaram hipereosinofilia com um padrão perinuclear negativo de autoanticorpos citoplásmicos antineutrófilos (p-ANCA). A biópsia de pele demonstrou vasculite leucocitoclástica com infiltração eosinofílica, diante de uma angiografia coronária normal. Os sintomas do paciente melhoraram com metilprednisolona IV, pulsoterapia com ciclofosfamida e azatioprina.

Eosinophilic granulomatosis with polyangiitis is a rare primary vasculitic disease characterized by hypereosinophilia, late onset asthma and extravascular eosinophil granulomas. We report a case presented initially with acute myocardial infarction which later only proceed with asthma, skin manifestations and peripheral neuropathy. Laboratory parameters showed hypereosinohpilia with negative perinuclear pattern of antineutrophil cytoplasmic autoantibodies (p-ANCA). Skin biopsy showed leucocytoclastic vasculitis with eosinophilic infiltration while coronary angiography was normal. The patient's symptoms improved with IV methylprednisolone, pulse cyclophosphamide and azathioprine.

A Rare Cause of Peripheral Vascular Thrombosis: Hypereosinophilia Caused by Toxocara canis Infection / 대한내과학회지

Hypereosinophilia is often associated with eosinphilic infiltration of tissue, which can lead to severe and irreversible organ damage. One of the most characteristic and critical complications is development of thrombosis in cardiac ventricles, and occasionally in deep veins. We report a rare case of hypereosinophilia, with peripheral vascular thrombosis, caused by Toxocara canis infection.

Reversible Encephalopathy Caused by Reactive Hypereosinophilia due to Toxocariasis

A 69-year-old male admitted to the psychological department due to delusion. One week later, he developed pneumonia and deep drowsy mental status. Despite improvement of pneumonia, his mental status got worse and he was referred to neurological department. The complete blood count tests showed repeated hypereosinophilia. The serologic tests revealed toxocariasis. He was treated with steroid and albendazole and his mental state rapidly improved. Toxocariasis is a common cause of reactive hypereosinophilia, which may be an underestimated etiology of reversible encephalopathy.

Cause and incidence of eosinophilia in children: a single center study in one year

PURPOSE: Eosinophilia may be associated with various primary and reactive conditions. However, studies on the cause and incidence of eosinophilia in Korean children are rare. This study aimed to evaluate the cause and incidence of eosinophilia in patients at a single university hospital. METHODS: We studied 8,285 pediatric patients under the age of 18 years who had eosinophilia at Pusan National University Hospital. Premature and newborn infants were excluded. Eosinophilia was defined as an absolute eosinophil count greater than 450/microL. Eosinophilia was categorized as mild (450-1,500/microL), moderate (1,500-5,000/microL), and severe (>5,000/microL). The underlying conditions of eosinophilia were retrospectively investigated. RESULTS: Of 8,285 patients who had a hematology profile, 497 (5.9%) were found to have eosinophilia. Of patients with eosinophilia, 333 patients (67.0%) had identifiable and possible causes. The major causes of eosinophilia were allergic diseases (61.3%), infectious diseases (19.8%), immunologic diseases (9.0%) and hemato-oncologic disease (5.1%). Immunological disease such as Idiopathic hypereosinophilic syndrome, drug induced hypersensitivity syndrome and Graft-versus-host disease was the common condition with moderate to severe eosinophilia in which eosinophil count in peripheral blood was more than 1,500/microL. CONCLUSION: The most common cause of eosinophilia was allergic disease. Immunological disease was the common condition with moderate to severe eosinophilia.

Different Lesion Patterns in Cerebral Infarction Associated with Hypereosinophilic Syndrome

Hypereosinophilic syndrome is a rare disorder that can cause ischemic stroke. We report two patients with cerebral infarction due to hypereosinophilic syndrome. Brain MRI of each patient revealed different lesion patterns of cerebral infarcts, which included multiple border-zone infarcts and a small perforating-artery infarct. The mechanism underlying the small infarct in one of the patients was presumed to be vascular endothelial toxicity by eosinophilic cells and local thrombus formation, and the distinguishing lesion pattern of this patient has not been reported previously.

Chronic eosinophilic leukemia with a unique translocation.

We report a case of chronic eosinophilic leukemia in a 9 year old girl who presented with anemia, thrombocytopenia, leucocytosis (mostly dysplastic eosinophils), lymphadenopathy and hepatosplenomegaly. There was no increase in blasts but myelofibrosis was seen in the bone marrow. A previously unreported translocation 46,XX,t(1;4)(q24;q35), was found on cytogenetic analysis and involvement of the myocardium was also present. Shortly after commencing steroids, the family abandoned therapy.

Incidence and Causes of Hypereosinophilia in the Patients of a University Hospital / 대한진단검사의학회지

BACKGROUND: Eosinophilia may be associated with various primary and reactive conditions. The incidence and the causes of eosinophilia might have been changed according to the changes in the incidence of diseases such as cancer, chronic degenerative diseases, etc. We have conducted a retrospective study to investigate the incidence and causes of eosinophilia. METHODS: Eosinophilia and hypereosinophilia were defined when absolute eosinophil count was greater than 500/microL and 1,500/microL, respectively. Patient's clinical records were reviewed to find out the underlying clinical conditions responsible for causes of hypereosinophilia. Conventional chromosomal analysis, reverse transcriptase PCR and FISH for gene rearrangement were performed to check the presence of clonal eosinophilia. RESULTS: Out of 41,137 patients who had a hematology profile performed, 5,019 (12.2%) and 373 patients (0.9%) were found to have eosinophilia and hypereosinophilia, respectively. Among patients with hypereosinophilia, 227 patients (60.9%) had identifiable and/or possible causes. The major causes of hypereosinophilia were malignancy (35.2%), allergy and skin diseases (18.1%), infectious diseases (15.4%), hepatobiliary diseases (7.5%), bone marrow clonal diseases (6.6%) and parasite infections (6.6%). We also found a rare case of FIP1L1-PDGFRalpha positive chronic eosinophilic leukemia combined with light chain multiple myeloma. CONCLUSIONS: We found a difference in the distribution of causes of hypereosinophilia in comparison with previous Korean studies, and the most common cause of hypereosinophilia in the current study was malignancy. A rare case of clonal eosinophilia (chronic eosinophilic leukemia) associated with multiple myeloma was confirmed using molecular studies.

Acute Lymphoblastic Leukemia with Chromosomal Translocation t (5; 14) (q31; q32) and Hypereosinophilia in a Child / 대한소아혈액종양학회지

Hypereosinophilia has been associated with a variety of underlying disorders such as parasitic, fungal and mycobacterial infections, allergic disorders, collagen vascular diseases, or hypereosinophilic syndrome (HES). The association of acute lymphoblastic leukemia (ALL) and symptomatic eosinophilia is rare and only a few cases have been reported. HES probably occurs in less than 1% of all patients with ALL. The chromosomal translocation t (5; 14) (q31; q32) was cloned at the molecular level in ALL with eosinophilia. This translocation joined the immunoglobulin heavy chain region to the promoter region of the interleukin-3 (IL-3) gene in opposite transcriptional orientation. The IL-3 gene translocated with the immunoglobulin heavy chain gene may play a central role in the pathogenesis of this leukemia and the associated eosinophilia. We describe a 8-year-old boy who presented with hypereosinophilia and concurrent ALL with t (5; 14).

A clinical analysis of 53 cases of hypereosinophilia / 中国实用内科杂志

Objective To comprehend the etiology and the clinical characteristics of hypereosinophilia.Methods The clinical data of 53 patients with hypereosinophilia admitted to Peking Union Medical College Hospital from November 1992 to February 2005 were analyzed.Results The causes of reactive hypereosinophilia included allergic diseases,infections,connective tissue diseases,malignant diseases,lung diseases,eosinophilic gastroenteritis.idiopathic hypereosinophilic syndrome had longer course of disease;more organ involved than reactive causes.The incidence of lymph node enlargement,spleen enlargement and thrombus was higher than the reactive.IHES had higher level of white blood cell count,absolute eosinophilic count,IgG and CRP.Conclusion The etiology and clinical characteristics of hypereosinophilia are various,so the differential diagnosis of hypereosinophilia is very important.
