Abstract
Eosinophil-associated diseases are characterized by a common pathogenetic background, represented by eosinophil-led inflammation and overexpression of interleukin (IL)-5. IL-5 and its receptor are excellent therapeutic targets for eosinophil-associated diseases. Three monoclonal antibodies targeting IL-5 currently are available: mepolizumab and reslizumab block circulating IL-5 preventing the binding to its receptor, whereas benralizumab binds to IL-5 receptor α. They have a steroid-sparing effect in eosinophil disorders, such as eosinophilic granulomatosis with polyangiitis, hypereosinophilic syndrome, allergic bronchopulmonary aspergillosis, eosinophilic esophagitis, and chronic eosinophilic pneumonia. The biotechnological drugs targeting IL-5 are promising therapies; however, further studies are needed.

Abstract
Treatment of eosinophilic dermatosis of hematologic malignancy (EDHM) has been challenging with a minimal response to several modalities. Only systemic corticosteroids have consistently proven successful in suppressing the rash; however, the response is often only partial, and symptoms tend to recur as the dosage is tapered. This demonstrates the need for effective maintenance therapy. Herein, we present a case of EDHM that, following a 1 month prednisone taper and brief trial of narrow-band ultraviolet B phototherapy, has remained well-controlled with omalizumab. This suggests that omalizumab may represent an effective therapeutic alternative in EDHM management with low long-term toxicity.

Abstract
Eosinophilic disorders and related syndromes represent a heterogeneous group of neoplastic and nonneoplastic conditions, characterized by more eosinophils in the peripheral blood, and may involve eosinophil-induced organ damage. In the WHO classification of myeloid and lymphoid neoplasms, eosinophilic disorders characterized by dysregulated tyrosine kinase (TK) fusion genes are recognized as a new category termed, myeloid/lymphoid neoplasms with eosinophilia and rearrangement of PDGFRA, PDGFRB or FGFR1 or with PCM1-JAK2. In addition to these aforementioned TK fusion genes, rearrangements involving FLT3 and ABL1 genes have also been described. These new NCCN Guidelines include recommendations for the diagnosis, staging, and treatment of any one of the myeloid/lymphoid neoplasms with eosinophilia (MLN-Eo) and a TK fusion gene included in the 2017 WHO Classification, as well as MLN-Eo and a FLT3 or ABL1 rearrangement.

Eosinophilia Associated With CD3 -CD4 + T Cells: Characterization and Outcome of a Single-Center Cohort of 26 Patients. Front Immunol 2020; 11:1765. [PMID: 32849632 PMCID: PMC7432433 DOI: 10.3389/fimmu.2020.01765] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 07/01/2020] [Indexed: 12/21/2022] Open
Abstract
Background: Lymphocytic variant hypereosinophilic syndrome is characterized by marked over-production of eosinophilopoietic factor(s) by dysregulated T cells leading to eosinophil expansion. In most cases, these T cells are clonal and express a CD3-CD4+ phenotype. As this is a rare disorder, presenting manifestations, disease course, treatment responses, and outcome are not well-characterized. Materials and Methods: In this retrospective single-center observational study, we reviewed medical files of all patients with persistent hypereosinophilia seen between 1994 and 2019 in whom CD3-CD4+ T cells were detected. Data collection included clinical and biological findings at presentation, treatment responses, disease course, and serial CD3-CD4+ T cell counts. Results: Our cohort comprises 26 patients, including 2 with hypereosinophilia of undetermined significance. All 24 symptomatic patients had cutaneous lesions and/or angioedema, and fasciitis was present in several cases. The aberrant T cell subset represented 2% or less total lymphocytes in 11 subjects. TCR gene rearrangement patterns on whole blood were polyclonal in these cases, while they all had serum CCL17/TARC levels above 1,500 pg/ml. Disease manifestations were mild and did not require maintenance therapy in roughly one third of the cohort, while two thirds required long-term oral corticosteroids and/or second-line agents. Among these, interferon-alpha was the most effective treatment option with a response observed in 8/8 patients, one of whom was cured of disease. Treatment had to be interrupted in most cases however due to poor tolerance and/or development of secondary resistance. Anti-interleukin-5 antibodies reduced blood eosinophilia in 5/5 patients, but clinical responses were disappointing. A sub-group of 5 patients had severe treatment-refractory disease, and experienced significant disease- and treatment-related morbidity and mortality, including progression to T cell lymphoma in three. Conclusions: This retrospective longitudinal analysis of the largest monocentric cohort of CD3-CD4+ T cell associated lymphocytic variant hypereosinophilic syndrome published so far provides clinicians confronted with this rare disorder with relevant new data on patient presentation and outcome that should help tailor therapy and follow-up to different levels of disease severity. It highlights the need for novel therapeutic options, especially for the subset of patients with severe treatment-refractory disease. Future research efforts should be made toward understanding CD3-CD4+ T cell biology in order to develop new treatments that target primary pathogenic mechanisms.

Abstract
OBJECTIVES To provide an in-depth review of the classification and diagnostic evaluation of hypereosinophilia (HE), with a focus on eosinophilic neoplasms. METHODS A review of published literature was performed, and exemplary HE cases were identified. RESULTS Causes of HE are diverse and can be grouped under three categories: primary (neoplastic), secondary (reactive), and idiopathic. Advances in cytogenetics and molecular diagnostics have led to elucidation of the genetic basis for many neoplastic hypereosinophilic disorders. One common molecular feature is formation of a fusion gene, resulting in the expression of an aberrantly activated tyrosine kinase (TK). The World Health Organization endorsed a biologically oriented classification scheme and created a new major disease category, namely, "myeloid/lymphoid neoplasms with eosinophilia and rearrangement of PDGFRA, PDGFRB or FGFR1, or with PCM1-JAK2." Rearrangement of other TK genes and activating somatic mutation(s) in TK genes have also been reported in eosinophilic neoplasms. Diagnostic evaluation of HE involves a combination of clinical, histopathologic, and immunophenotypic analyses, as well as molecular genetic testing, including next-generation sequencing-based mutation panels. The management of primary HE is largely guided by the underlying molecular genetic abnormalities. CONCLUSIONS A good knowledge of recent advances in HE is necessary to ensure prompt and accurate diagnosis, as well as to help optimize patient care.

Abstract
Aim: To investigate eosinophilia as a potential on-treatment biomarker for patients receiving cancer immunotherapy. Materials & methods: We evaluated the association between eosinophilia and treatment response and toxicity in a retrospective cohort of patients receiving cancer immunotherapy. Results: The study involved 146 patients. Eosinophilia developed in 22%. Patients who developed eosinophilia were more likely to achieve disease control (p = 0.009), with every 0.1 × 109/l rise in eosinophil count, while receiving treatment was associated with a 28% relative increased chance achieving disease control. Although there was a trend toward improved survival, there was no significant association between eosinophilia and improved overall survival (p = 0.136). Patients with eosinophilia were more likely to develop toxicity (p = 0.042). Conclusion: Eosinophilia is a potentially useful biomarker warranting further prospective clinical investigation. Immunotherapy has revolutionized the way we treat many cancers. However, we do not have good predictors for which patients are going to respond to treatment or experience side effects. ‘Eosinophilia’ is when a particular type of white blood cell is present at high levels in the blood. This can occur in patients on immunotherapy. This paper reports a possible link between eosinophilia and the likelihood of responding well to immunotherapy but also the possibility of developing side effects.

Abstract
Hypereosinophilic syndrome (HES) is a rare but life-threatening multi-organ disease which can be complicated by stroke, with devastating outcomes. Eosinophils can accumulate in multiple organs, most commonly involving the heart, skin, lungs, spleen, and liver. Neurological end-organ complications in hypereosinophilic syndrome are unusual and have been established to be of three types: brain infarction, encephalopathy and sensory polyneuropathy. We present a case where acute ischaemic stroke and encephalopathy are early manifestations of Idiopathic HES. It is important to consider HES as an aetiology for stroke and a high eosinophil count is an initial diagnostic clue. Early initiation of steroid therapy can potentially prevent disease progression.

Abstract
Background Hypereosinophilia (HE) is defined by the presence of >1.5 × 109/L eosinophils in the peripheral blood. Paraneoplastic HE has been reported in a number of solid and hematologic malignancies including ovarian cancer. We present a case with paraneoplastic HE in the setting of underlying endometrioid ovarian carcinoma. Case presentation An 88-year-old woman presented with cough, dyspnea and 20-pound unintentional weight loss of one month duration. Evaluation revealed peripheral hypereosinophilia (HE) with absolute eosinophil count of 15.38 × 109/L (53.8%) and an elevated exhaled nitric oxide at 172 parts per billion (normal < 39 PPB). Given the HE and unintentional weight loss, computed tomography (CT) scan was obtained and showed a pelvic mass. The patient underwent bilateral salpingo-ophorectomy with pathology consistent with endometrioid ovarian carcinoma. The patient experienced complete resolution of her cough, dyspnea, and peripheral eosinophilia following surgical resection. Conclusion This case highlights that solid malignancy should be considered in patients with marked HE.

Abstract
Immunocheckpoint inhibitor (ICI) therapy has provided significant clinical improvements in the treatment of several malignancies. The purpose of this report is to increase awareness of hypereosinophilia associated with checkpoint inhibitors, a topic that has been rarely reported. Hypereosinophilia may need to be addressed especially if eosinophil counts increase to levels where hypereosinophilic visceral complications can occur. We are presenting a case of a 57-year-old male with hypereosinophilia that was seen in the setting of progression of metastatic non-small-cell lung cancer during and after nivolumab treatment.

Abstract
Hypereosinophilic syndrome (HES) is an uncommon syndrome characterized by peripheral blood eosinophils count of more than 1,500/mm3 with associated tissue damage. It can be either primary or secondary, for example, due to parasitic infections or inflammation. We present a case of a 49-year-old Asian female with recurrent hospital admissions for cholecystitis, gastritis, urinary cystitis, and pancreatitis. Her peripheral blood count showed excessive eosinophils 15,600-19,000/mm3 on different occasions. Pathology of her gallbladder and her gastric biopsies showed eosinophilic infiltration. Her bone marrow biopsy showed a normocellular marrow with active trilineage hematopoiesis, eosinophilia, mild megakaryocytic hyperplasia with a few atypical forms, and mild T-cell lymphocytosis. Flow cytometry showed no evidence of acute leukemia, or T-cell or B-cell lymphoproliferative disorder. On fluorescent in-situ hybridization (FISH), myeloproliferative neoplasms (MPN) testing was negative for platelet-derived growth factor receptor-alpha (PDGFRA), platelet-derived growth factor receptor-beta (PDGFRB), and fibroblast growth factor receptor-1 (FGFR1) rearrangement. Despite not having the FIP1L1‐PDGFRA (factor interacting with PAPOLA and CPSF1-platelet-derived growth factor receptor, alpha polypeptide) gene fusion, our patient responded to the treatment with a significant decrease in her absolute eosinophils count and resolution of her symptoms.

Abstract
Rearrangements of PDGFRB are defining cytogenetic abnormalities seen in "Myeloid/lymphoid neoplasms with eosinophilia and rearrangement of PDGFRB" and are generally evident by common cytogenetic methods. Here we present an unique case in which karyotyping and fluorescence in situ hybridization (FISH) analysis were negative, and the PDGFRB rearrangement was detected by next-generation sequencing (NGS) analysis. The patient presented with approximately one-year history of leukocytosis including neutrophilia, eosinophilia, basophilia and granulocytic left shift. Bone marrow biopsy revealed a hypercellular marrow with panmyelosis, eosinophilia and mast cell hyperplasia. Blasts were not increased. Ancillary studies revealed a normal karyotype and absence of BCR-ABL1 fusion gene. NGS identified AFAP1L1-PDGFRB fusion, which was confirmed by polymerase chain reaction amplification followed by direct Sanger sequencing. The patient was treated with imatinib and showed normalization of peripheral blood leukocytosis, which lasted for at least six months. This case highlights that cytogenetics/FISH study alone may be insufficient to detect all PDGFRB rearrangement, which is critical for the patient's management. We suggest that molecular analysis capable of detecting fusion genes should be performed in all similar cases.

FIP1L1-PDGFRA-Positive Hypereosinophilia Presenting with Bilateral Extracranial Carotid Artery Aneurysms. World Neurosurg 2020; 139:419-422. [PMID: 32360918 DOI: 10.1016/j.wneu.2020.04.119] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2020] [Revised: 04/13/2020] [Accepted: 04/15/2020] [Indexed: 11/17/2022]
Abstract
OBJECTIVE To describe a case of an adult female Filipino with hypereosinophilia and bilateral carotid artery aneurysms who subsequently developed bilateral cerebral hemisphere strokes following aneurysm stenting. CASE DESCRIPTION A 57-year-old female patient with persistent hypereosinophilia presented with progressively enlarging bilateral neck masses, revealed to be carotid artery aneurysms on computed tomography angiography. Following surgical exploration, she later developed right-sided hemiplegia, aphasia, and right hemianopia. Cranial computed tomography revealed infarcts on both middle cerebral artery territories. Bone marrow biopsy and fluorescent in situ hybridization revealed findings suggestive of hypereosinophilic syndrome. She was started on standard aspirin and statin therapy and was discharged sixteen days after the procedure. Partial improvement of neurologic deficits was noted two months later on follow up. Chemotherapy with imatinib was initiated. CONCLUSIONS This patient's prothrombotic state from FIP1L1-PDGFRA-positive hypereosinophilia may have led to large carotid artery aneurysm formation and intramural thrombosis. This case demonstrates a possible and heretofore undocumented neurovascular sequela of hypereosinophilic syndrome.

Abstract
Primary systemic vasculitides are rare diseases affecting blood vessel walls. The type and patterns of distribution of the organs affected usually reflect the size of the vessels predominantly involved, and the patterns of clinical manifestations are generally useful to reach a specific diagnosis. However, presenting symptoms may lack adequate specificity for a prompt diagnosis, leading to a diagnostic (and therapeutic) delay, often causing irreversible damage to the affected organs. Due to their rarity and variable clinical presentation, the diagnosis of primary vasculitides could be challenging for physicians. Vasculitis mimickers, i.e. the clinical conditions that could be likely mistaken for vasculitides, need to be carefully ruled out, especially before starting the immunosuppressive therapy. We present here a practical approach to the diagnosis of primary systemic vasculitides involving large, medium and small size vessels, and reviewed most of the conditions that could mimic primary systemic vasculitides.

Abstract
BACKGROUND Episodic angioedema with eosinophilia (EAE, Gleich syndrome) is a rare disease, consisting of recurrent angioedema with hypereosinophilia and frequent increased serum immunoglobulin M levels. Less than 100 patients have been reported, mainly adults, sometimes with underlying lymphocytic variant of hypereosinophilic syndrome (HESL ). The aim of this study was to identify and describe pediatric cases. METHODS We performed a retrospective study of all pediatric cases of EAE referred within the French National Referral Center for Hypereosinophilic Syndrome (CEREO). Next, the PRISMA guidelines were applied in order to perform a systematic review (data sources: PubMed, Web of Science). RESULTS Among the two reported and 15 previously published cases of EAE occurring in children, the main clinical findings mimicked those of adults, including recurrent angioedema, hives, and weight gain. The median time between the first angioedema flare and the diagnosis of EAE was 5 years in published cases. Hypereosinophilia was constant, usually worsening with each attack, but seldom disappeared between flares. Total IgM serum levels were elevated in 16 patients. Four children had evidence of abnormal CD3- CD4+ T cells. First-line therapy relied on oral corticosteroids in all patients, and further lines (used in five patients) included interferon-α, methotrexate, and cyclosporin. Two children developed eosinophilic myocarditis during follow-up. CONCLUSION Pediatricians should be aware that EAE is a diagnosis to consider in children. T-cell immunophenotyping is warranted in this setting. Prognosis seems fair, yet eosinophil-related organ damage may occur in patients with persistent eosinophilia.

Abstract
BACKGROUND The increasing incidence of life-threatening Pneumocystis pneumonia (PCP) in non-HIV immunocompromised patients is a global concern. Yet, no reports have examined the prognostic significance of pre-existing interstitial lung disease (ILD) in non-HIV PCP. METHODS We retrospectively reviewed the medical records of non-HIV PCP patients with (ILD group) or without (non-ILD group) pre-existing ILD. The clinical features and outcomes of the ILD group were compared with those of the non-ILD group. Cox regression models were constructed to identify prognostic factors. RESULTS 74 patients were enrolled in this study. The 90-day mortality was significantly higher in the ILD group than in the non-ILD group (62.5% versus 19.0%, p<0.001). In the ILD group, patients with a higher percentage of bronchoalveolar lavage fluid neutrophils had worse outcomes compared to those having a lower percentage (p=0.026). Multivariate analyses revealed that pre-existing ILD (p=0.002) and low levels of serum albumin (p=0.009) were independent risk factors for 90-day mortality. Serum levels of β-d-glucan were significantly reduced after treatment of PCP in both groups, whereas levels of Krebs von den Lungen-6 (KL-6) significantly increased in the ILD group. In the ILD group, the 90-day mortality of patients with increasing KL-6 levels after treatment was significantly higher than those with decreasing levels (78.9% versus 0%, p=0.019). CONCLUSION In non-HIV PCP patients, pre-existing ILD is associated with a poorer prognosis. Prophylaxis for PCP is needed in patients with pre-existing ILD under immunosuppression.

Abstract
INTRODUCTION Clinical presentation of cholesterol crystal embolism (CCE) can be dermatologic when cholesterol crystals become lodged in small cutaneous arteries resulting in ischemia. We report a case of CCE with erythroderma misleading to a diagnostic of drug reaction with eosinophilia and systemic symptoms (DRESS). CASE REPORT A 66 year-old woman presented with erythroderma few months after initiation of allopurinol. Acute renal failure was present with elevation in plasma creatinine concentration (523μmol/L) and hypereosinophilia (HE) (5666/mm3). Finally, the REGISCAR score helped to rule out DRESS diagnostic. Past blood-count tests were analyzed revealing chronic HE present before allopurinol initiation. Renal biopsy identified CCE. CONCLUSION This case is the first to report a DRESS like presentation of CCE. Clinical findings are secondary to HE and not to occlusion of cutaneous arteries.

Abstract
Immune checkpoint inhibitors have changed the treatment paradigm for patients with cancer. Though a majority of patients tolerate treatment, some develop hematologic toxicities, including eosinophilia. Eosinophilia has been associated with better responses in some patients with melanoma, but this has not been investigated in non-small-cell lung cancer. We present a case of a woman with metastatic lung adenocarcinoma who developed asymptomatic hypereosinophilia after initiation of nivolumab. Her eosinophil count temporarily decreased after transiently stopping the medication, but increased again after re-initiation. She had a favorable tumor response to therapy. This exemplifies the potential role of eosinophilia as a peripheral, readily available biomarker of favorable response to immunotherapy in patients with lung cancer. Awareness of this manifestation is important.

Abstract
BACKGROUND Lymphocytic variant of hypereosinophilic syndrome (L-HES) is a subtype of HES driven by cytokines produced by clonal T-cells. Due to the rarity of its occurrence and challenges in diagnosis, this subtype of HES is under recognized. METHODS AND RESULTS We report seven patients with L-HES, diagnosed from a group of 136 patients who were referred to our institution for the work-up of hypereosinophilia. The clinical presentation, symptoms and signs were heterogeneous and uncharacteristic; indistinguishable from idiopathic HES. Flow cytometry immunophenotypic analysis revealed aberrant T-cells in all patients, with a Th2 immunophenotype, CD2 + CD3-CD4 + CD5 + CD7dim+/-CD8- in six of seven (86%) cases. CD10 was partially expressed in one of seven (14%) cases, and clonal TCR gene rearrangement was detected by PCR in five of seven (71%) patients. All patients were treated with corticosteroids and two of seven (29%) patients received anti-IL5 antibody therapy. With a median follow-up time of 7.5 years (2.3-14.1 years), one (11%) patient developed peripheral T-cell lymphoma 6.1 years after the initial diagnosis of L-HES and responded well to chemotherapy. All patients were alive at the last follow-up. CONCLUSION In conclusion, a combination of flow cytometry immunophenotyping and molecular analysis allows the identification of aberrant T-cells, facilitating a diagnosis of L-HES in patients with eosinophilia. A correct diagnosis is essential for the proper management of these patients.

Abstract
Primary systemic vasculitides are rare diseases that may manifest similarly to more commonly encountered conditions. Depending on the size of the vessel affected (large vessel, medium vessel, or small vessel), different vasculitis mimics must be considered. Establishing the right diagnosis of a vasculitis mimic will prevent unnecessary immunosuppressive therapy.

Abstract
Hypereosinophilic syndrome (HES) is a rare multisystem disease that predominantly includes skin with severe and persistent itching. A lack of understanding about the pathological condition and mechanism of dermatosis caused by HES hinders its treatment. In the present study, we applied a quantitative proteomics approach to characterize the cellular responses of skin tissue to idiopathic HES (IHES) at the proteome level. We identified hundreds of skin tissue proteins that were differentially expressed between IHES patients and healthy individuals. IHES patients display severely damaged microenvironment, including extracellular matrix (ECM) organization and disassembly, immune disorders, decreased metabolic capacity, and susceptibility to microbial infection. Moreover, there was abnormal proliferation of basal epidermal stem cells, which was closely related to high expression of the epigenetic regulator, histone deacetylase 2, providing mechanistic insight into the abnormal epidermal thickening of IHES skin tissues. Overall, our study provides a comprehensive framework for a system-level understanding of IHES-induced dermatosis (IHESiD) tissues at the protein and cell pathway levels. Our findings may facilitate a new approach to diagnosis and treatment to alleviate skin clinical symptoms, monitor the activity of IHES, and determine therapeutic effects.

Abstract
Endomyocardial fibrosis (EMF) affects approximately 12 million persons worldwide and is an important cause of restrictive cardiomyopathy in the developing world, with the highest prevalence reported in sub-Saharan Africa, South Asia, and South America. EMF is characterized by apical filling with fibrotic tissue of one or both ventricles, often associated with thrombus, calcification, and atrioventricular valve regurgitation, leading to typical symptoms of restrictive heart failure. Transthoracic echocardiography (TTE) is the first-line modality for assessment of EMF, basically owing to its widespread availability. However, in recent years cardiac MRI has emerged as a powerful tool for assessment of cardiac morphology and function, with higher accuracy than TTE, along with the unique advantage of being able to provide comprehensive noninvasive tissue characterization. Delayed enhancement (DE) imaging is the cornerstone of cardiac MRI tissue characterization and allows accurate identification of myocardial fibrosis, conveying valuable additional diagnostic and prognostic information. The typical DE pattern in EMF, described as the "double V" sign, consists of a three-layered pattern of normal myocardium, thickened enhanced endomyocardium, and overlying thrombus at the apex of the affected ventricle; it has excellent correlation with histopathologic findings and plays an important role in differentiating EMF from other cardiomyopathies. Conversely, fibrous tissue deposition quantified using DE imaging, when indexed to body surface area, has been shown to be a strong independent predictor of mortality. The aim of this review is to summarize state-of-the-art applications of cardiac MRI for diagnostic and prognostic assessment of patients with suspected or confirmed EMF. Online supplemental material is available for this article. ©RSNA, 2020.

Abstract
The human eosinophil has long been thought to favorably influence innate mucosal immunity but at times has also been incriminated in disease pathophysiology. Research into eosinophil biology has uncovered a number of interesting contributions by eosinophils to health and disease. However, it appears that not all eosinophils from all species are created equal. It remains unclear, for example, exactly how having eosinophils benefits the human host when helminth infections in the developed world have become scarce. This review focuses on our current state of knowledge as it relates to human eosinophils. When information is lacking, we discuss lessons learned from mouse studies that may or may not directly apply to human biology and disease. It is an exciting time to be an "eosinophilosopher" because the use of biologic agents that selectively target eosinophils provides an unprecedented opportunity to define the contribution of this cell to eosinophil-associated human diseases.

Abstract
Introduction: Eosinophilic granulomatosis with polyangiitis (EGPA) usually occurs in patients with late-onset asthma and sustained peripheral blood eosinophilia and classically presents with a clinical multifaceted spectrum of manifestations, which may vary at the different stages of the natural history of the disease.Areas covered: We reviewed EGPA clinical presentation, focusing on clinical manifestations at three different phases of the disease: 1/before the development of overt vasculitis, 2/at vasculitis diagnosis and 3/during the long-term follow-up. An update on current classification criteria and recent therapeutic advances has been provided as well.Expert opinion: Asthma, chronic rhinosinusitis and blood eosinophilia could anticipate the overt vasculitis for years. An atopic background may be present in a subset of patients (25-30%), while ANCA presence varies between 10 and 40%. Systemic vasculitis rapidly occurs and clinical features demonstrating vasculitis processes (neuropathy, purpura, scleritis, alveolar hemorrhage and glomerulonephritis) develop along with systemic symptoms (50%). After vasculitis resolution, asthma remains severe in up to 50% of patients and incidence of isolated-asthma and rhinosinus exacerbations remains constantly high. Different sets of classification criteria have been published so far, and DCVAS diagnostic criteria will be presented soon. Interleukin-5 blockers seem to be promising to control the disease and to spare corticosteroids.

Abstract
The genetic basis of myocarditis remains an intriguing concept, at least as long as the definition of myocarditis constitutes the definitive presence of myocardial inflammation sufficient to cause the observed ventricular dysfunction in the setting of cardiotropic infections. Autoimmune or immune-mediated myocardial inflammation constitutes a complex area of clinical interest, wherein numerous and not yet fully understood role of hereditary auto-inflammatory diseases can result in inflammation of the pericardium and myocardium. Finally, myocardial involvement in hereditary immunodeficiency diseases, cellular and humoral, is a possible trigger for infections which may complicate the diseases themselves. Whether the role of constitutional genetics can make the patient susceptible to myocardial inflammation remains yet to be explored.

Abstract
Physicians may encounter blood or tissue eosinophilia through a routine complete blood count with differential or a tissue pathology report. In this article, the basic biology of eosinophils is reviewed and definitions of blood eosinophilia, as well as the challenges of defining tissue eosinophilia, are discussed. Conditions associated with eosinophilia are briefly discussed as well as a general approach to evaluating eosinophilia. Future challenges include determining which eosinophil-associated diseases benefit from eosinophil-targeted therapy and identifying biomarkers for disease activity and diagnosis.

Abstract
Eosinophilia is not a rare finding in clinical practice, and often poses problems in terms of etiologic research and differential diagnosis. Peripheral eosinophilia is defined by a blood eosinophil count > 500 cells/μL. It is classified into mild (500-1500 cells/μl), moderate (1500-5000 cells/μl) and severe for an eosinophil count > 5000 cells /μl. The term "hypereosinophilia" defines a condition characterized by a blood eosinophil count >1500 cells/μl in at least two consecutive tests made with a minimum of a 4-week interval. The causes of eosinophilia are various, and can be summarized by the acronym "APLV" which refers to Allergic disorders, Parasitic infections, Leukemia/ Lymphomas (and solid tumors) and Vasculitis-Immunodeficiency diseases, with allergic disorders and parasitic infections representing the most commonly identified causes. Allergic disorders are usually associated with mild eosinophilia, whereas values >20.000 cell/μl are highly suggestive for myeloproliferative disorders. Eosinophils may also be directly responsible for organ damage, mainly at cardiac, pulmonary and cutaneous level, deriving from the release of the granule products, of lipidic mediators and cytokines. Therefore, in the physician's approach to a patient with persistent hypereosinophilia, it is also important to investigate the presence of organ involvement. In this review, we propose a diagnostic algorithm for children presenting with either blood eosinophilia or hypereosinophilia. This algorithm focuses on the patient's history and clinical manifestations as the first step and the level and persistence of blood eosinophilia as the second, and this can help the physician to identify patients presenting with an elevated blood eosinophil count that need further laboratory or instrumental investigations.

Abstract
BACKGROUND The absence of asthma may rule out a diagnosis of eosinophilic granulomatosis with polyangiitis in patients with hypereosinophilic syndrome (HES) and features of vasculitis. OBJECTIVE To describe eosinophilic vasculitis (EoV) as a possible manifestation of HES in asthma-free patients. METHODS We screened our hospital database and the literature for patients with HES who met the following 4 criteria: (1) histopathological or clinical features of EoV (biopsy-proven vasculitis with predominant eosinophilic infiltration of the vessel wall and/or features of vasculitis with tissue and/or blood hypereosinophilia [absolute eosinophil count >1.5 G/L]); (2) no other obvious causes of reactive eosinophilia, organ damage, and vasculitis; (3) the absence of antineutrophil cytoplasmic antibodies; and (4) the absence of current asthma. RESULTS Ten of our 83 (12%) asthma-free patients with HES and 107 additional cases in the literature met the criteria for EoV. After a critical analysis of the patients' clinical and laboratory characteristics and outcomes, we identified 41 cases of single-organ EoV (coronary arteritis, n = 29; temporal arteritis, n = 8; cerebral vasculitis, n = 4). Of the remaining 76 patients with EoV, the most frequent manifestations (>10%) were cutaneous vasculitis (56%), peripheral neuropathy (24%), thromboangiitis obliterans-like disease (16%), fever (13%), central nervous system involvement (13%), deep venous thrombosis (12%), and nonasthma lung manifestations (12%). Blood hypereosinophilia more than 1.5 G/L was observed in 79% of patients, and necrotizing vasculitis was observed in 44%. CONCLUSIONS Our results suggest that idiopathic EoV (HES-associated vasculitis) can be classified as an eosinophilic-rich, necrotizing, systemic form of vasculitis that affects vessels of various sizes in asthma-free patients.

Abstract
Systemic mastocytosis (SM) is frequently associated with eosinophilia. To examine its prevalence and clinical impact in all WHO classification-based subcategories, we analyzed eosinophil counts in 2350 mastocytosis patients using the dataset of the European Competence Network on Mastocytosis. Ninety percent of patients had normal eosinophil counts, 6.8% mild eosinophilia (0.5-1.5 × 109/l), and 3.1% hypereosinophilia (HE; >1.5 × 109/l). Eosinophilia/HE were mainly present in patients with advanced SM (17%/19%), and only rarely recorded in patients with indolent and smoldering SM (5%/1%), and some patients with cutaneous mastocytosis. The eosinophil count correlated with organomegaly, dysmyelopoiesis, and the WHO classification, but not with mediator-related symptoms or allergy. Eosinophilia at diagnosis had a strong prognostic impact (p < 0.0001) on overall survival (OS) and progression-free survival (PFS), with a 10-year OS of 19% for patients with HE, 70% for those with mild eosinophilia, and 88% for patients with normal eosinophil counts. In 89% of patients with follow-up data (n = 1430, censored at start of cytoreductive therapy), eosinophils remained stable. In those with changing eosinophil counts (increase/decrease or mixed pattern), OS and PFS were inferior compared with patients with stable eosinophil counts. In conclusion, eosinophilia and HE are more prevalent in advanced SM and are predictors of a worse outcome.

Abstract
A 46-year-old woman consulted our hospital with diffuse alopecia and blood eosinophilia. Histological examination of the scalp revealed dense eosinophilic infiltration around the hair follicles and in the surrounding subcutis. Oral corticosteroid was effective to reduce hair loss and blood eosinophilia, but these conditions immediately relapsed after ending treatment. In addition to alopecia, she had diarrhea and colitis showing histological findings of dense eosinophilic infiltrations in the submucosa. We diagnosed hypereosinophilic syndrome based on hypereosinophilia of blood and tissue with clinical symptoms of alopecia and diarrhea. We suppose diffuse alopecia showing massive eosinophilic infiltration around the hair follicle is a rare symptom of hypereosinophilic syndrome.

Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA) (formerly Churg-Strauss syndrome) is a small vessel vasculitis associated with asthma and eosinophilia. Despite its rarity, continuous gains are being made in understanding the disease with knowledge advancements regarding its epidemiology, heterogeneous clinical manifestations, management, and outcomes. Large knowledge gaps remain, however, particularly surrounding pathophysiologic and diagnostic uncertainties. There is still an incomplete understanding of the interplay between the eosinophilic and vasculitic processes that are features of disease pathogenesis. EGPA is also a conceptually difficult disorder given its dual categorization with hypereosinophilic syndromes and systemic vasculitides and the absence of a biomarker that can reliably distinguish between the two. In addition, recent evidence points to distinct, but partly overlapping, disease phenotypes, yet there is insufficient understanding to inform phenotype-tailored therapies. EGPA also remains a diagnostic challenge in part because asthma may be the primary or predominant manifestation for years, and the chronic corticosteroid requirement may mask other disease features. Efforts are ongoing to better elucidate pathophysiologic mechanisms, resolve classification issues, better characterize disease manifestations, and further clarify disease subcategorization, all of which will translate into better diagnosis and treatment with the possibility of specifically adapted therapies.

Abstract
Background Loiasis is mostly considered a relatively benign infection when compared with other filarial and parasitic diseases, with Calabar swellings and eyeworm being the most common signs. Yet, there are numerous reports in the literature of more serious sequelae. Establishing the relationship between infection and disease is a crucial first step toward estimating the burden of loiasis. Methods We conducted a systematic review of case reports containing 329 individuals and detailing clinical manifestations of loiasis with a focus on nonclassical, atypical presentations. Results Results indicate a high proportion (47%) of atypical presentations in the case reports identified, encompassing a wide range of cardiac, respiratory, gastrointestinal, renal, neurological, ophthalmological, and dermatological pathologies. Individuals with high microfilarial densities and residing in an endemic country were at greater risk of suffering from atypical manifestations. Conclusions Our findings have important implications for understanding the clinical spectrum of conditions associated with Loa loa infection, which extends well beyond the classical eyeworm and Calabar swellings. As case reports may overestimate the true rate of atypical manifestations in endemic populations, large-scale, longitudinal clinico-epidemiological studies will be required to refine our estimates and demonstrate causality between loiasis and the breadth of clinical manifestations reported. Even if the rates of atypical presentations were found to be lower, given that residents of loiasis-endemic areas are both numerous and the group most at risk of severe atypical manifestations, our conclusions support the recognition of loiasis as a significant public health burden across Central Africa.

Abstract
Eosinophilic myocarditis is a rare form of myocarditis that may manifest from cancer-mediated inflammation. A case of eosinophilic myocarditis secondary to metastatic melanoma is described; metastatic melanoma can cause a T helper type 2 lymphocyte-mediated increase in circulating levels of interleukin-5, which is known to stimulate eosinophil proliferation resulting in myocardial inflammation and fibrosis. Cardiac imaging with transesophageal echocardiography revealed a large immobile left ventricular apical thrombus. Cardiac MRI was then performed and revealed enhancing fibrosis along the endocardial surface. © RSNA, 2019 Supplemental material is available for this article.

Abstract
Eosinophilic myocarditis is a rare form of myocarditis that may manifest from cancer-mediated inflammation. A case of eosinophilic myocarditis secondary to metastatic melanoma is described; metastatic melanoma can cause a T helper type 2 lymphocyte-mediated increase in circulating levels of interleukin-5, which is known to stimulate eosinophil proliferation resulting in myocardial inflammation and fibrosis. Cardiac imaging with transesophageal echocardiography revealed a large immobile left ventricular apical thrombus. Cardiac MRI was then performed and revealed enhancing fibrosis along the endocardial surface. © RSNA, 2019 Supplemental material is available for this article.

Budd-Chiari Syndrome Associated With Hypereosinophilic Syndrome Treated by Deceased-Donor Liver Transplantation: A Case Report. Transplant Proc 2019; 51:3140-3146.

Abstract
INTRODUCTION Budd-Chiari syndrome (BCS) associated with hypereosinophilic syndrome (HES) is very rare, and only a few reports have described its treatment. Furthermore, no report to date has described the performance of liver transplantation for the treatment of BCS associated with HES. We herein describe a 54-year-old man who underwent deceased-donor liver transplantation (DDLT) for treatment of BCS associated with HES. CASE A 54-year-old man was found to have an increased eosinophil count during a medical check-up. After exclusion of hematopoietic neoplastic diseases and secondary eosinophilia, idiopathic hypereosinophilia was diagnosed. Oral prednisolone was administered to the patient, and his eosinophil count immediately decreased to a normal level. He had an uneventful course without complications for 11 months but then presented with bloating and malaise. Imaging studies including ultrasonography, enhanced computed tomography, and angiography revealed BCS associated with HES. Transjugular intrahepatic portosystemic shunt failed because of complete obstruction of the hepatic veins. Therefore, the patient was introduced to our hospital for liver transplantation. DDLT was performed with venovenous bypass 1 month after the patient was placed on the DDLT waiting list. The explanted hepatic veins were completely occluded and organized. The patient's eosinophil count was maintained at a normal level with prednisolone treatment after DDLT. CONCLUSIONS Liver transplantation can be a treatment option for BCS associated with HES if neoplastic diseases and secondary eosinophilia have been excluded. Life-long oral steroid therapy is required to control HES even after liver transplantation.

Abstract
Introduction: Hypereosinophilic syndromes are a heterogeneous group of disorders that may be associated with life-threatening organ injury as a result of tissues infiltration by eosinophils. The main goal of therapy is to mitigate eosinophil-mediated organ damage. When possible, therapy should be directed at the underlying etiology. However, even in the absence of any known cause, when organ damage is present, hypereosinophilia must be treated promptly and aggressively to reduce potential morbidity and mortality.Areas covered: Conventional therapies, including corticosteroids, hydroxyurea (hydroxycarbamide) and interferon-alpha, have shown variable efficacy and a non-negligible toxicity emphasizing the need of new therapeutic strategies based on drugs with different mechanisms of action.Expert opinion: Tyrosine kinase inhibitors have a central role among targeted therapies of hypereosinophilic syndromes. Imatinib, initially empirically used based on its activity in chronic myeloid leukemia, achieved preliminary excellent results further confirmed in large series of patients. Third-generation tyrosine kinase inhibitors such as ponatinib, while active in vitro and in vivo in animals, still deserve confirmation in properly designed clinical trials. In addition, clinical investigation on monoclonal antibodies against interleukin-5, interleukin-5Rα, IgE, and CD52 represents a promising area of research.

An Intriguing Case of Eosinophilia with FIP1L1/PDGFRA Rearrangement Who Presented as Thrombotic Thrombocytopenic Purpura. Case Rep Hematol 2019; 2019:2820954. [PMID: 31737382 PMCID: PMC6815613 DOI: 10.1155/2019/2820954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 08/25/2019] [Accepted: 09/07/2019] [Indexed: 11/17/2022] Open
Abstract
Myeloid neoplasm with eosinophilia and FIP1-like-1-platelet-derived growth factor receptor-alpha (FIP1L1-PDGFRA) rearrangement is a multi-organ disease with diverse clinical presentation. Thrombotic thrombocytopenic purpura (TTP) is characterized by the concomitant occurrence of often severe thrombocytopenia, microangiopathic hemolytic anemia, and a variable degree of ischemic organ damage. To our knowledge, only one case of eosinophilia with FIP1L1-PDGFRA rearrangement presented as a case of thrombotic thrombocytopenic purpura reported in the literature. We herein report a case of a young male patient with hypereosinophilic syndrome and FIP1L1-PDGFRA rearrangement who presented with asthma, transient ischemic attacks (TIA), and confusion. He had an acquired TTP that was successfully treated with plasma exchanges (PLEX), corticosteroids, rituximab, and later with the addition of imatinib mesylate (Gleevec, Novartis). He remains in complete remission on imatinib 100 mg daily for more than 28 months of follow-up.
