Eosinophilic Granulomatosis With Polyangiitis Following COVID-19 Vaccination: A Case Report

The current emergence of the coronavirus disease 2019 (COVID-19) pandemic and the possible side effects of COVID-19 mRNA vaccination remain worrisome. Few cases of vaccination-related side effects, such as vasculitis, have been reported. Eosinophilic granulomatosis with polyangiitis (EGPA), also known as Churg-Strauss syndrome, is a type of vasculitis characterized by the histological richness of eosinophils, asthma, polyneuropathy, sinusitis, and skin or lung involvement. Here, we report the first case of new onset EGPA following COVID-19 vaccination in Korea. A 71-year old woman developed a skin rash and presented with progressive weakness of the upper and lower extremities after the BNT162b2 vaccination (Pfizer-BioNTech). She was diagnosed with EGPA and her symptoms improved after systemic steroid and immunosuppressant therapy. Although it is very rare, clinicians should be aware that EGPA may occur after COVID-19 vaccination.

Eosinophilic granulomatosis with polyangiitis complicated with rapidly progressive glomerulonephritis in a young man who is a healthy cyclist

Eosinophilic granulomatosis with polyangiitis (EGPA), formerly known as Churg-Strauss syndrome, is a rare systemic vasculitis. Rapidly progressive glomerulonephritis (RPGN) is a rare complication of EGPA. We report a case of a 60-year-old man, who is also a skilled cyclist, who was hospitalized to investigate a symptomatology that had arisen over the previous months and worsened in the last few weeks, to the point of limiting normal everyday activities. The physical examination revealed the presence of livedo reticularis of the four limbs, purpura of the lower limbs, arthritis of the ankles, and low-grade fever; the patient showed intense asthenia, loss of appetite, retrosternal heartburn, and a scarcely pharmacologically controlled asthma. He also reported weight loss (about 5 kg in the last 6 months). Rapidly progressing renal failure was observed with hyper-eosinophilia (4.7 thousand/μL eosinophils, 44% of total leukocytes), pulmonary opacities on chest computed tomography (CT), and sinusitis on CT of the facial massif. The search for antibodies directed against neutrophil cytoplasm (ANCA) revealed a high level of pANCA (pANCA ++, ELISA anti-MPO 666 UI/ml), associated with an increment of inflammation indicators. The induction therapy was high-dosage intravenous glucorticoids and cyclophosphamide, to improve the short and long-term prognosis. After 7 months of treatment, the patient reported a considerable improvement of the symptoms, which at that point did not necessitate pharmacological interventions. The eosinophils value was 0 cells/mm³, the inflammation indexes were back to the norm, and the renal function appeared significantly improved.

A Case of Eosinophilic Granulomatosis with polyangiitis Presenting with Mononeuritis Multiplex

BACKGROUND

Eosinophilic Granulomatosis with Polyangiitis (EGPA), also known as Churg Strauss Syndrome, is an uncommon vasculitis associated with antineutrophil cytoplasmic antibody (ANCA). The hallmarks of the disease are asthma, eosinophilia and systemic vasculitis with varying degrees of neurological, cutaneous, cardiac, gastrointestinal and renal involvement. Diagnosisis often difficult since the symptoms are diverse,and a number of differentials need to be excluded.

CASE PRESENTATION

In this report,we describe a 60-year-old patient who presented with mononeuritis multiplex and painful skin rash. A history of late-onset asthma which was poorly controlled led us to suspect EGPA. Laboratory data showed, leukocytosis, eosinophilia(>10%), elevated ESR, CRP and IgE, normal chest Xray, positive Rheumatoid factor (RA) and perinuclear anti-neutrophil cytoplasmic antibody (p-ANCA) and evidence of extravascular eosinophils in histopathology report of skin biopsy.She was treated with Methylprednisolone and cyclophosphamide pulse therapy with a satisfactory response.

CONCLUSION

Diagnosis of EGPA requires a combination of clinical and histopathological findings to meet the diagnostic criteria. A history of poorly controlled or late-onset asthma may guide us to the diagnosis that is frequently overlooked. Due to the wide heterogeneity of EGPA patients' phenotypes, sharp professional judgment is needed for early disease detection and treatment in order to avoid irreversible changes and poor outcomes.

Churg-Strauss Syndrome Along with Cardiac Complications

Churg-Strauss syndrome (CCS) or eosinophilic granulomatosis with polyangiitis is a rare condition, which is a challenge for both diagnosis and treatment in clinical work. Occurrences of cardiac complications represent a negative predictor of treatment outcome for these patients. The aim of this article is to present the diagnostic and therapeutic modality of a 33-year-old male diagnosed with? CCS. Treatment of these patients should be multidisciplinary, with a comprehensive therapeutic modality, while early diagnosis is imperative.

Heart disease in a mutant mouse model of spontaneous eosinophilic myocarditis maps to three loci

Background

Heart disease (HD) is the major cause of morbidity and mortality in patients with hypereosinophilic diseases. Due to a lack of adequate animal models, our understanding of the pathophysiology of eosinophil-mediated diseases with heart complications is limited. We have discovered a mouse mutant, now maintained on an A/J inbred background, that spontaneously develops hypereosinophilia in multiple organs. Cellular infiltration into the heart causes an eosinophilic myocarditis, with affected mice of the mutant line (i.e., A/J^HD) demonstrating extensive myocardial damage and remodeling that leads to HD and premature death, usually by 15-weeks old.

Results

Maintaining the A/J^HD line for many generations established that the HD trait was heritable and implied the mode of inheritance was not too complex. Backcross and intercross populations generated from mating A/J^HD males with females from four different inbred strains produced recombinant populations with highly variable rates of affected offspring, ranging from none in C57BL/6 J intercrosses, to a few mice with HD using 129S1/SvImJ intercrosses and C57BL/6 J backcrosses, but nearly 8% of intercrosses and > 17% of backcrosses from SJL/J related populations developed HD. Linkage analyses of these SJL/J derived recombinants identified three highly significant loci: a recessive locus mapping to distal chromosome 5 (LOD = 4.88; named Emhd1 for eosinophilic myocarditis to heart disease-1); and two dominant variants mapping to chromosome 17, one (Emhd2; LOD = 7.51) proximal to the major histocompatibility complex, and a second (Emhd3; LOD = 6.89) that includes the major histocompatibility region. Haplotype analysis identified the specific crossovers that defined the Emhd1 (2.65 Mb), Emhd2 (8.46 Mb) and Emhd3 (14.59 Mb) intervals.

Conclusions

These results indicate the HD trait in this mutant mouse model of eosinophilic myocarditis is oligogenic with variable penetrance, due to multiple segregating variants and possibly additional genetic or nongenetic factors. The A/J^HD mouse model represents a unique and valuable resource to understand the interplay of causal factors that underlie the pathology of this newly discovered eosinophil-associated disease with cardiac complications.

Cutaneous Vasculitis as Early Presentation of Eosinophilic Granulomatosis with Polyangiitis without Systemic Symptoms

Eosinophilic granulomatosis with polyangiitis (formerly known as Churg-Strauss syndrome) is a rare vasculitis in children. It commonly presents with respiratory symptoms, especially asthma, allergic rhinitis, and peripheral eosinophilia. Involvement of other systems, such as renal and cardiac, may carry a poor prognosis. Anti-neutrophil cytoplasmic antibodies have been found less frequently in children with this condition. We report a case of a 15-year-old male who presented with indurated and pruritic papules on both legs and peripheral eosinophilia without other system involvement. Histopathological findings from a skin biopsy were suggestive of eosinophilic granulomatosis with polyangiitis. Anti-neutrophil cytoplasmic antibodies were negative.

Eosinophilic granulomatosis with polyangiitis and laryngeal involvement: review of the literature and a cross-sectional prospective experience

BACKGROUND

Eosinophilic granulomatosis with polyangiitis and granulomatosis with polyangiitis show variable otorhinolaryngological involvement. Up to 14 per cent of granulomatosis with polyangiitis patients have subglottis involvement; little is known about the laryngeal involvement in eosinophilic granulomatosis with polyangiitis.

METHOD

A literature review was conducted, together with a prospective cross-sectional analysis of 43 eosinophilic granulomatosis with polyangiitis patients. All patients underwent fibre-optic laryngoscopy with narrow-band imaging, and completed health-related questionnaires.

RESULTS

The literature review showed only two cases of laryngeal involvement in eosinophilic granulomatosis with polyangiitis; in our cohort, no cases of subglottis stenosis were found, but local signs of laryngeal inflammation were present in 72 per cent of cases. Of the patients, 16.2 per cent had a pathological Reflux Finding Score (of 7 or higher).

CONCLUSION

Laryngeal inflammation in eosinophilic granulomatosis with polyangiitis is frequent. It is possibly due more to local factors than to eosinophilic granulomatosis with polyangiitis itself. However, ENT evaluation is needed to rule out possible subglottis inflammation. These findings are in line with current literature and worthy of confirmation in larger cohorts.

ANCA Glomerulonephritis and Vasculitis

ANCA vasculitis has an associated autoimmune response that produces ANCAs that induce distinct pathologic lesions. Pauci-immune necrotizing and crescentic GN is a frequent component of ANCA vasculitis. ANCA vasculitis is associated with ANCA specific for myeloperoxidase (MPO-ANCA) or proteinase 3 (PR3-ANCA). A diagnosis of ANCA vasculitis should always specify the serotype as MPO-ANCA positive, PR3-ANCA positive, or ANCA-negative. To fully characterize a patient, the serotype also should be accompanied by the clinicopathologic variant if this can be determined: microscopic polyangiitis, granulomatosis with polyangiitis (Wegener), eosinophilic granulomatosis with polyangiitis (Churg-Strauss), or renal-limited vasculitis. ANCA vasculitis is most prevalent in individuals >50 years old. There are racial/ethnic and geographic influences on the prevalence, serotype frequencies, and clinicopathologic phenotypes. There is clinical, in vitro, and animal model evidence that ANCAs cause disease by activating neutrophils to attack small vessels. Immunomodulatory and immunosuppressive therapies are used to induce remission, maintain remission, and treat relapses. Over recent years, there have been major advances in optimizing treatment by minimizing toxic therapy and utilizing more targeted therapy.

A Rare Right Ventricular Involvement of Eosinophilic Granulomatosis Demonstrated by Cardiac MRI

BACKGROUND

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis with a prevalence rate of seven per million. Cardiac involvement was reported in 20-50%, yet with improved diagnostic methods, the frequency of cardiac involvement is expected to be even higher. It can result in significant morbidity and mortality, accounting for about 50% of death. Cardiac magnetic resonance (CMR) imaging is used to evaluate the myocardium, valves, coronary arteries, pericardium, also to assess cardiac structure and function. Perfusion study allows tissue characterisation with a suggestive pattern of late gadolinium enhancement.

CASE REPORT

We report a rare case of EGPA in a 54-year-old male patient who presented with fever, sore throat and dizziness. Echocardiography showed a filling defect at the apex of the right ventricle (RV). CMR findings suggested the diagnosis of EGPA by demonstrating an impressive lesion at RV apex with the typical 3-layer appearance and thrombus formation. Post-gadolinium subendocardial hyperenhancement suggested focal involvement at the inferolateral wall of the left ventricle. Computed Tomography (CT) was done to rule out calcific or soft plaques of the coronary arteries, small vessel vasculitis and small aneurysm. CT scan showed a low-attenuation lesion at the inner wall of the right ventricle. In the lungs, bilateral interstitial changes and bilateral cystic bronchiectases were found. Under appropriate treatment, the patient improved clinically.

CONCLUSIONS

It is of crucial importance to perform full cardiac imaging that includes CMR even in asymptomatic patients with suspected EGPA, since early identification of cardiac involvement may allow to apply appropriate therapy and full recovery of the patient.

Small bowel involvement documented by capsule endoscopy in Churg-Strauss syndrome

Churg-Strauss syndrome is a small and medium vessel vasculitis and is also known as allergic granulomatous angiitis. Gastrointestinal involvement is common in patients with Churg-Strauss syndrome (20-50%). The most common symptoms are abdominal pain, diarrhoea and occasionally gastrointestinal bleeding and perforation. We present a case of Churg-Strauss syndrome with small bowel lesions documented by video capsule endoscopy.

[Cardiac tamponade and myocarditis in Churg-Strauss syndrome]

INTRODUCTION

The successive occurrence of pericardial tamponade and myocarditis during a Churg-Strauss syndrome is exceptionally described. We report a patient in whom pericardial tamponade and myocarditis were the presenting manifestation of a Churg-Strauss syndrome.

CASE REPORT

A 58-year-old woman was admitted because of alteration of the clinical status with eosinophilia. One month ago, she was hospitalized for a pericardial tamponade treated by pericardial drainage. Acute myocarditis was diagnosed on chest pain during the second hospitalization. The etiologic inquiry ended in the diagnosis of Churg-Strauss complicated with a double cardiac involvement. A good response of clinical and biological anomalies was obtained after corticosteroid and immunosuppressive treatment.

CONCLUSION

Isolated or multiple involvements of cardiac tunics should lead to make diagnosis of systemic vasculitis. A complete initial assessment and a close observation of the patients followed for Churg-Strauss syndrome is imperative to detect a cardiac achievement and set up an early treatment.

Juvenile churg-strauss syndrome as an etiology of myocarditis and ischemic stroke in adolescents; a case report

BACKGROUND

Churg-Strauss syndrome (CSS), a systemic vasculitis accompanied by asthma and eosinophilia, almost invariably affects the lung and is frequently associated with cutaneous involvement. It rarely has cardiac involvement. We report an unusual case of CSS with myocardial involvement and stroke.

CASE PRESENTATION

A 16-year old female suffered of allergic asthma for 4 years. She was under treatment with oral prednisolone and seretide inhalation. After CSS diagnosis, she developed paroxysmal atrial tachycardia. Serum levels of Troponin I and Troponin T were increased indicating massive myocardial damage probably due to myocarditis. After 5 months she developed acute hemiparesis without any evidence of ischemic or hemorrhagic event. She was treated with IVIg, intravenous pulses of methylprednisone and cyclophosphamide for each complication.

CONCLUSION

Myocarditis and stroke may also complicate CSS which should be taken in consideration for better management.

Churg-strauss syndrome without respiratory symptoms in a child

Churg-Strauss Syndrome (CSS) is rare in children. It consists of a small- and medium-sized vessel vasculitis, with skin and peripheral nerve involvement. It is characterized by eosinophilia, extravascular necrotizing granuloma, and eosinophilic infiltration of multiple organs particularly the lungs, but may also involve the gastrointestinal tract, the heart, and the kidneys. The condition is usually associated with a preceding history of asthma or allergic sinusitis. It has rarely been reported in children, where most of the cases had pre-existing asthma, allergic rhinitis, or atopic disease. We report a 10-year-old Arab girl proven to have CSS, with no history of asthma or allergic rhinitis, who presented with tender cutaneous nodules of lower extremities, foot drop, and peripheral eosinophilia, without any clinical respiratory symptoms or signs.
