Eosinophilic Granulomatosis

A case of eosinophilic granulomatosis with polyangiitis (EGPA) in which chronic rhinosinusitis (CRS) was improved with a reduction in the myeloperoxidase-antineutrophil cytoplasmic antibody (MPO-ANCA) titer after the addition of mepolizumab is reported. A 55-year-old woman with EGPA receiving prednisolone 5 mg/day developed CRS with increases in the eosinophil count and the MPO-ANCA titer. Although it improved with prednisolone 15 mg/day in addition to mizoribine 150 mg/day, because azathioprine could not be taken orally due to side effects, it relapsed after prednisolone was tapered to 5 mg/day. There was no exacerbation of other vasculitis symptoms such as mononeuropathy multiplex. The patient was treated with additional mepolizumab 300 mg every 4 weeks, which resulted in the improvement of CRS and marked reductions of the eosinophil count and MPO-ANCA titer, and the reduction of prednisolone to 2 mg/day. Furthermore, even after tapering mepolizumab to 200 mg every 4 weeks, her condition remained stable without relapse of EGPA and without increases in the eosinophil count and MPO-ANCA titer. The clinical course of mepolizumab treatment in this patient suggests that the IL5-dependent inflammatory cascade is one of the factors contributing to the increase in MPO-ANCA in EGPA.

Abstract Background Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic necrotizing vasculitis mainly affecting small-sized arteries. Involvement of medium-sized vessels is very rare in EGPA. Here we present the case of a patient with EGPA who showed multiple hepatic aneurysms and distal gangrene. Case presentation A known EGPA patient visited to the emergency room (ER) with abrupt squeezing abdominal pain. She had suffered from gangrene in the fingertips of both hands for 1 year because of arterial thrombosis associated with hypereosinophilia. However, her absolute eosinophil count in the ER was 1120 cells/µL. An abdomen-pelvis CT demonstrated subcapsular hematoma in the right hepatic lobe. A celiac angiogram demonstrated multiple sized aneurysms in both hepatic lobes and some aneurysms in S7 and S8 were huge, more than 1 cm in size. The shape of the small aneurysms resembled a string of beads, as in polyarteritis nodosa. Given the clinical situation, emergency embolization was performed. Before this patient visited to the ER, she had been treated with a high dose of systemic corticosteroid, azathioprine, and cyclophosphamide. After addition of mepolizumab, the eosinophil count remained stable state with a near zero percentage of total white blood cell count. Conclusions Aneurysm and gangrene resulting from the involvement of medium-sized vessels can occur in EGPA. Destruction of vessels might occur even if eosinophil count is below 1500 cells/µL. If involvement of medium-sized arteries is suspected, thorough investigation to identify the involved organs and prompt management are needed to prevent fatal complications.

Eosinophilic Granulomatosis

This chapter covers the connective tissue diseases including systemic lupus erythematosus, Sjögren’s syndrome, scleroderma, antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (including granulomatosis with polyangiitis (formerly known as Wegener’s granulomatosis), eosinophilic granulomatosis with polyangiitis (formerly known as Churg–Strauss syndrome), and microscopic polyangiitis), polyarteritis nodosa, and Behçet’s disease. For each example of a connective tissue disease it provides an overview of the condition and classification criteria, alongside the prognosis. Techniques and tricks for diagnosis, clinical features, assessment tools, and treatment are all covered. Key points of nursing care are described, including the nurse’s role in treatment with thalidomide and cyclophosphamide, and any particular organs that can be affected is detailed.

Common Manifestation

Vasculitis refers to inflammation of blood vessel walls that results in vascular wall destruction and ischemic injury to affected organs. Common vasculitides discussed herein include Takayasu arteritis (TAK), giant cell arteritis (GCA), antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides such as granulomatosis with polyangiitis (GPA) and eosinophilic granulomatosis with polyangiitis (EGPA), and anti-glomerular basement membrane (anti-GBM) disease or Goodpasture syndrome. Vasculitides are further subcategorized depending of the size of the predominantly affected vessels: large, medium and small vessel vasculitis. The affected vessel size strongly influences the clinical and imaging manifestations of the disease. Intrathoracic involvement is more common in small and large vessel vasculitides. Diffuse alveolar hemorrhage (DAH), a common manifestation of vasculitis, is considered a syndrome rather than a specific entity and will be discussed in this chapter. However, it should be noted that DAH may also result from non-vasculitic etiologies. The work up and diagnosis of patients with primary vasculitides is challenging and requires close collaboration between the clinician, the radiologist and the pathologist. Radiographic abnormalities are non specific or may be absent. CT and MRI are the imaging modalities of choice for the evaluation and follow up of these patients, and should be considered despite normal radiographics.

ObjectiveReported prevalence of vasculitic neuropathy (VN) in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is highly variable, and associations with other organ manifestations have not been studied systematically while accounting for diagnostic certainty of VN.MethodsData of all patients with AAV within the Diagnostic and Classification criteria for primary systemic VASculitis study were analyzed cross-sectionally. VN was categorized as definite (histology proven), probable (multiple mononeuropathy or nerve biopsy consistent with vasculitis), or possible (all others). Associations with other organ manifestations were compared in patients with and without VN.ResultsNine hundred fifty-five patients (mean age 57 years, range 18–91 years, 51% female) were identified. Of these, 572 had granulomatosis with polyangiitis (GPA), 218 microscopic polyangiitis (MPA), and 165 eosinophilic granulomatosis with polyangiitis (EGPA). The prevalence of VN was 65% in EGPA, 23% in MPA, and 19% in GPA. Nerve biopsy was performed in 32/269 (12%) patients, demonstrating definite vasculitis in 17/32 (53%) of patients. VN was associated with myeloperoxidase-ANCA positivity (p = 0.004) and skin (p < 0.001), musculoskeletal, (p < 0.001) and cardiovascular (p = 0.005) involvement. Patients with VN were less likely to have renal (p < 0.001), eye (p < 0.001), and gastrointestinal (p = 0.023) involvement.ConclusionsOur study provides comprehensive insights into the prevalence and organ associations of VN in a large, systematically collected AAV cohort. VN is most commonly associated with skin, musculoskeletal, and cardiovascular manifestations. In routine clinical practice, diagnosis of VN is infrequently confirmed by the gold standard of nerve biopsy but rather supported by the clinical setting of active systemic AAV.

Abstract Objectives: Mepolizumab (MPZ), an anti-interleukin-5 antibody, is effective for treating eosinophilic granulomatosis with polyangiitis (EGPA). However, its effectiveness has not been adequately evaluated in real-world clinical practice. In this study, we assessed the effectiveness and safety of 300 mg MPZ for relapsing/refractory EGPA resistant to corticosteroids (CS) for 1 year in real-world settings. Methods: We administered MPZ (300 mg) to 16 patients with relapsing/refractory EGPA resistant to CS (with-MPZ). We also retrospectively collected data from the same patients for 12 months before administering MPZ (without-MPZ). The primary endpoint was the 12-month remission rate after MPZ administration, and the secondary endpoints were the Birmingham vasculitis activity score (BVAS), vasculitis damage index (VDI), eosinophil count, changes in concomitant CS doses/concomitant immunosuppressant use, MPZ retention rate, and incidence of adverse events. The clinical course was compared between Without-MPZ and With MPZ.Results: The 12-month remission rate after initiating MPZ was 75%. No change was observed in BVAS, eosinophil count, or concomitant CS dose in the without-MPZ, whereas all these parameters were significantly decreased in the with-MPZ. The number of patients on concomitant immunosuppressants also decreased in the with-MPZ. VDI did not increase in both groups. The MPZ retention rate was 100%, and only three patients (18.8%) had infections.Conclusion: This study demonstrated that MPZ is effective and safe for EGPA, furthermore, compared to Without-MPZ, MPZ improves disease activity and possesses a higher remission rate and CS sparing effect.
