Myopericarditis as a presentation of eosinophilic granulomatosus with polyangiitis (EGPA).

A 60-year-old woman was admitted to the hospital with worsening dyspnoea, cough and chest pain. This was on a background of weight loss, decreased appetite, mononeuritis multiplex, chronic eosinophilia and a single episode of a non-blanching rash. Investigations demonstrated a raised troponin and ischaemic changes on ECG, and she was therefore initially treated for a presumed myocardial infarction. However, her symptoms failed to improve with treatment for the acute coronary syndrome. A coronary angiogram revealed no significant flow-limiting disease, and further investigations yielded confirmation of raised eosinophils and a positive perinuclear antineutrophil cytoplasmic antibody test. An echocardiogram demonstrated a pericardial effusion, and subsequent cardiac magnetic resonance features were compatible with myopericarditis. In light of these findings, the patient was diagnosed with eosinophilic granulomatous with polyangiitis and commenced on high-dose intravenous methylprednisolone and cyclophosphamide. She made an excellent recovery and remains in remission on azathioprine and a tapering dose of corticosteroids.

Clinicopathological Features, Risk Factors and Predispositions, and Response to Treatment of Eosinophilic Oral Disease in 24 Dogs (2000-2016).

The objectives of this study were to retrospectively describe clinicopathological features of eosinophilic oral disease in dogs, to identify possible risk factors or predispositions to the condition, and to report overall treatment response. Canine medical records from a veterinary teaching hospital and private referral practice over a 17-year period were reviewed for a diagnosis of eosinophilic oral disease. Twenty-four dogs with 26 lesions met the inclusion criteria. Patient mean age and body weight were 6.8 (3.8) years and 13.4 kg, respectively. Fifteen breeds were represented including Cavalier King Charles spaniel (16.7%), Labrador retriever (12.5%), and West Highland white terrier (12.5%). Eosinophilic lesions were found in the palate (65.4%), tongue (26.9%), and other oral locations (7.7%). Median follow-up time was 5 months. Analysis revealed statistically significant associations between lesion location and body weight (palatal and tongue lesions were more likely in smaller dogs, whereas lesions in the other category [lip or mucosa] were more likely in larger dogs). There was a correlation in lesion location and resolution (all dogs with palatal lesions became asymptomatic at their last recheck), and resolution and the use of antibiotics plus prednisone (greater likelihood of resolution without the use of this combination). Seventy percent of asymptomatic dogs resolved without medication or with allergen therapy alone, suggesting that asymptomatic dogs may respond well to conservative management. No associations were found between lesion location and breed, signalment and response to therapy, lesion resolution and the use of glucocorticoids, or significance of peripheral eosinophilia.

Evaluation of clinical benefit from treatment with mepolizumab for patients with eosinophilic granulomatosis with polyangiitis.

BACKGROUND: In a recent phase III trial (NCT02020889) 53% of mepolizumab-treated versus 19% of placebo-treated patients with eosinophilic granulomatosis with polyangiitis (EGPA) achieved protocol-defined remission. OBJECTIVE: We sought to investigate post hoc the clinical benefit of mepolizumab in patients with EGPA using a comprehensive definition of benefit encompassing remission, oral glucocorticoid (OGC) dose reduction, and EGPA relapses. METHODS: The randomized, placebo-controlled, double-blind, parallel-group trial recruited patients with relapsing/refractory EGPA receiving stable OGCs (prednisolone/prednisone, ≥7.5-50 mg/d) for 4 or more weeks. Patients received 300 mg of subcutaneous mepolizumab or placebo every 4 weeks for 52 weeks. Clinical benefit was defined post hoc as follows: remission at any time (2 definitions used), 50% or greater OGC dose reduction during weeks 48 to 52, or no EGPA relapses. The 2 remission definitions were Birmingham Vasculitis Activity Score of 0 plus OGC dose of 4 mg/d or less (remission 1/clinical benefit 1) or 7.5 mg/d or less (remission 2/clinical benefit 2). Clinical benefit was assessed in all patients and among subgroups with a baseline blood eosinophil count of less than 150 cells/µL, baseline OGC dosage of greater than 20 mg/d, or weight of greater than 85 kg. RESULTS: With mepolizumab versus placebo, 78% versus 32% of patients experienced clinical benefit 1, and 87% versus 53% of patients experienced clinical benefit 2 (both P < .001). Significantly more patients experienced clinical benefit 1 with mepolizumab versus placebo in the blood eosinophil count less than 150 cells/µL subgroup (72% vs 43%, P = .033) and weight greater than 85 kg subgroup (68% vs 23%, P = .005); in the OGC greater than 20 mg/d subgroup, results were not significant but favored mepolizumab (60% vs 36%, P = .395). CONCLUSION: When a comprehensive definition of clinical benefit was applied to data from a randomized controlled trial, 78% to 87% of patients with EGPA experienced benefit with mepolizumab.

Canine eosinophilic granuloma of the digits treated with prednisolone and chlorambucil.

BACKGROUND: Canine eosinophilic granuloma (CEG) is an uncommon disease. Lesions are typically located in the oral cavity and other cutaneous sites, but are rarely reported to affect the digits. The majority of cases are treated with prednisolone as a monotherapy; alternative treatment options include corticosteroids administered in combination with azathioprine, antihistamines, electrochemotherapy with bleomycin, and surgical resection. Neither chlorambucil nor laser previously have been reported as treatments. OBJECTIVES: To describe an alternative therapy for treatment of CEG; using chlorambucil in combination with prednisolone for those cases that fail to respond to prednisolone alone. The new treatment was chosen according to good clinical practice and after owner consent. ANIMALS: Two client owned dogs. METHODS: One case was initially treated with carbon dioxide laser to debulk the lesions. Both cases were treated with a combination of oral prednisolone and chlorambucil. RESULTS: Both dogs experienced rapid resolution of lesions with prednisolone and chlorambucil therapy. Case 1 remained in remission three months after withdrawing medication. Case 2 experienced relapse 10 weeks after discontinuing therapy but was well controlled on maintenance prednisolone with chlorambucil at low, well tolerated doses. CONCLUSIONS AND CLINICAL IMPORTANCE: Although CEG appears to be an uncommon disease, it should be included as a differential diagnosis for dermal, nodular lesions affecting the digits. Chlorambucil appears to be an effective and well tolerated prednisolone sparing agent for treatment of CEG. Carbon dioxide laser ablation appears to be an effective method of debulking CEGs.

Eosinophilic granulomatosis with polyangiitis in childhood: retrospective experience from a tertiary referral centre in the UK.

OBJECTIVE: To describe the presenting clinical features, treatment and outcome in children with eosinophilic granulomatosis with polyangiitis (EGPA) and to define factors that predicted mortality. METHODS: A retrospective case notes review of patients fulfilling the Chapel Hill Consensus Conference definition and/or ACR criteria for EGPA seen at Great Ormond Street Hospital, London. Demographics, clinical features, histopathology, treatment and outcomes were recorded. Descriptive statistics were expressed as median and range. Fisher's exact test was used for group comparisons. The Paediatric Vasculitis Activity Score and Paediatric Vasculitis Damage Index (PVDI) were calculated. RESULTS: Thirteen children (38% female) aged at diagnosis 14.1 (4-15.6) years were identified. The median time to diagnosis was 2 (0-7.3) years. History of asthma was documented in 76%. The most common presenting features were pulmonary (69%), skin (61%), gastrointestinal (46%), cardiac involvement (46%), paranasal sinus abnormality (38%), arthritis/arthralgia (38%) and neurological involvement (15%). Paediatric Vasculitis Activity Score at presentation was 8/63 (2-25/63); ANCA was negative in all 10/13 patients tested. Treatment included corticosteroids in all, combined with CYC in 38% or AZA in 23%. PVDI at 12 (3-48) months follow-up was 3/72 (0-13/72). Relapses were recorded in 46%. Mortality was 15%; cardiomyopathy and PVDI scores ⩾5 significantly associated with mortality risk (P = 0.012). CONCLUSION: EGPA in the paediatric population is a rare and potentially life-threatening vasculitis. Increased awareness is essential to secure a timely diagnosis and to promptly initiate treatment since our data emphasize a high mortality, particularly in those with cardiac involvement and significant accrued damage.

New Finding in Vernal Keratoconjunctivitis: Splendore-Hoeppli Phenomenon.

PURPOSE: To report 2 cases of Splendore-Hoeppli phenomenon, a rare histopathologic observation, as a late clinical finding in vernal keratoconjunctivitis (VKC). METHODS: We report the cases of 2 young women with subconjunctival nodules as a manifestation of Splendore-Hoeppli phenomenon with a history of severe VKC. RESULTS: After eliminating other conditions causing such a reaction, both patients were treated using frequent topical corticosteroid, plus topical cyclosporine 2% in one of patient. Complete resolution was observed in both patients. CONCLUSIONS: The Splendore-Hoeppli phenomenon could be a part of VKC manifestations.

Intralesional Injection of Interferon-α2b in Orbital Eosinophilic Granuloma.

Considering the immune system dysfunction in unifocal orbital eosinophilic granuloma; possible complications of surgery, intralesional steroid, and radiotherapy; immunomodulatory and cytoreductive effects of interferon-α2b; and its safety profile in treatment of ocular surface neoplasia, intralesional interferon-α2b was first commenced in treatment of 3 cases (8-, 25-, and 43-year-old men) with biopsy proven orbital eosinophilic granuloma (2007-2014). Three intralesional injections of interferon-α2b (1.5 million units/0.5 ml) were given every other day. Cases 1 and 3 showed a rapid response with no recurrence in 86 and 29 months follow up. Case 2, however, required a second course of injection 2 months after the first one due to a partial response to the first injections with no recurrence at last follow up (57 months). Transient flulike symptom was the only side effect that was observed in Cases 2 and 3.

Granuloma faciale: a good therapeutic response with the use of topical tacrolimus.

Granuloma faciale is a rare dermatosis of chronic course, benign, usually asymptomatic, first described in 1945 by Wingley. It is characterized by the appearance of well-defined, single or multiple papules, plaques and nodules, predominantly located in sun-exposed areas, especially the face. In this work we report the case of a female patient, 58 years old, evolving for ten years with multiple erythematous-brownish and asymptomatic papules on the face, whose histological examination confirmed the diagnosis of granuloma faciale. The patient was treated with topical tacrolimus, evolving with regression of lesions.

Rituximab en el tratamiento de la granulomatosis eosinofílica con poliangitis / Rituximab in the treatment of eosinophilic granulomatosis with polyangiitis

Antecedentes: Algunos pacientes con granulomatosis eosinofílica con poliangitis (EGPA) y factores de mal pronóstico son refractarios o presentan efectos adversos al tratamiento de inducción (glucocorticoides [GC] y ciclofosfamida [CF]), o recaen durante el mantenimiento (GC y azatioprina), haciendo necesaria la búsqueda de alternativas terapéuticas. En ensayos clínicos, el rituximab (RTX) demostró ser eficaz para el tratamiento de las vasculitis asociadas al ANCA; sin embargo, los pacientes con EGPA no fueron incluidos. Objetivo: Revisar y analizar la bibliografía sobre la uso de RTX para el tratamiento de la EGPA. Métodos: La búsqueda se realizó en MEDLINE y LILACS (1965 y 1986, respectivamente, hasta febrero del 2014). Resultados: Se incluyó a 27 pacientes. La indicación de RTX fue por enfermedad refractaria (n = 20), recaída (n = 5) y nuevo diagnóstico (n = 2). Los órganos afectados fueron los pulmones, el sistema nervioso periférico, el riñón y los ojos. Se observó remisión en 16 y respuesta en 8 pacientes. Conclusiones: El RTX fue eficaz y bien tolerado para el tratamiento de la EGPA (AU)

Background: The general consensus is that for patients with EGPA with poor prognosis, intensive therapy with both GC and CF is indicated. The maintenance of remission is made with GC and AZA. A considerable number of patients with EGPA are refractory to first line therapy, experience dose-limiting side effects or relapse. In clinical trials, RTX was effective for the treatment of ANCA-associated vasculitis. However, patients with a diagnosis of EGPA were not included. Objective: to review and analyze the published literature regarding the use of RTX in the treatment of EGPA. Methods: The literature search was performed in MEDLINE and LILACS from 1965 and 1986 respectively until february 2014. Results: 27 patients were included. RTX treatment was due to refractory disease (n = 20), relapse (n = 5) and with newly diagnosed (n = 2). The affected organs were the lungs, peripheral nervous system, kidney and the eyes. Sixteen patients had clinical remission and 8 patients had clinical response. Conclusions: RTX was effective and well tolerated for the treatment of EGPA (AU)

Pneumonia associated with Salmonella spp. infection in a cat receiving cyclosporine.

Salmonellosis is uncommon in cats, usually affects the gastrointestinal tract or skin, and can be fatal. This report describes a domestic shorthair cat with severe pneumonia caused by Salmonella spp. without accompanying gastrointestinal or skin manifestations, in which previous administration of cyclosporine may have played a permissive role in its development. Clinical and laboratory findings as well as follow-up are described from diagnosis until complete recovery. This unusual presentation serves to alert practitioners to consider Salmonella spp. as a possible cause of lung disease in cats, especially if immunocompromised.

[Surgical treatment combined with oral administration of indomethacin for eosinophilic granuloma of the skull: report of a pediatric case].

A 13-year-old girl presented headache for 5 d upon admission to hospital. An initial CT revealed 3 lesions located in her skull, the sizes of which were 2.5 cm×3.2 cm,1.2 cm×1.0 cm,0.3 cm×0.3 cm, respectively. The largest lesion was resected by surgery and confirmed as eosinophilic granuloma by pathology. After surgery, she took oral indomethacin 25 mg b·i·d for 3 months and tolerated it well. CT scan was performed 3 months and 1 year later, and the results showed that the unresected lesions shrank progressively and the defected bones were regenerated and healed one year later after operation.

Primary atlantoaxial bone tumors in children: management strategies and long-term follow-up.

OBJECT: Atlantoaxial tumors account for a substantial proportion of primary bone tumors in children. Before resection, surgeons must consider the complex regional anatomy, the potential for neurological compromise, craniocervical instability, and the question of tumor resectability in a growing spine. Using current technology, the authors analyzed surgical cases in this light and present outcomes and treatment recommendations after long-term patient follow-up. METHODS: The authors reviewed clinical records for 23 children whose primary atlantoaxial bone tumors were treated from 1996 through 2010. RESULTS: Pathological lesions among the 23 patients were 4 aneurysmal bone cysts, 2 osteochondromas, 5 chordomas, 4 osteoblastomas, 3 fibrous dysplasias, 4 eosinophilic granulomas, and 1 Ewing's sarcoma. Clinical presentation consisted of neck pain (n = 23), headaches and occipital pain (n = 16), myelopathy (n = 8), and torticollis (n = 4). Selective angiography and coil embolization were undertaken for all patients with aneurysmal bone cysts and osteoblastomas, 2 patients with chordomas, 1 patient with fibrous dysplasia, and 1 patient with Ewing's sarcoma. Primary embolization treatment of radiation-induced aneurysmal bone cyst of the atlas showed complete reossification. Results of CT-guided needle biopsy were diagnostic for 1 patient with eosinophilic granuloma and 1 with Ewing's sarcoma. Needle biopsies performed before referral were associated with extreme blood loss for 1 patient and misdiagnosis for 2 patients. Surgery involved lateral extrapharyngeal, transoral, posterior, and posterolateral approaches with vertebral artery rerouting. Complete resection was possible for 9 patients (2 with osteochondroma, 3 with fibrous dysplasia, 2 with chordoma, and 2 with osteoblastoma). Decompression and internal fusion were performed for 3 patients with aneurysmal bone cysts. Of the 23 patients, 7 underwent dorsal fusion and 4 underwent ventral fusion of the axis body. Chemotherapy was necessary for the patients with eosinophilic granuloma with multifocal disease and for the patient with Ewing's sarcoma. There was no morbidity, and there were no deaths. All patients with benign lesions were free of disease at the time of the follow-up visit (mean ± SD follow-up 8.8 ± 1.1 years; range 2-18 years). Chordomas received proton or LINAC irradiation, and as of 4-15 years of follow-up, no recurrence has been noted. CONCLUSIONS: Because most atlantoaxial tumors in children are benign, an intralesional procedure could suffice. Vascular control and staged resection are critical. Ventral transoral fusion or lateral extrapharyngeal fusion has been successful. Resection with ventral fusion and reconstruction are essential for vertebral body collapse. Management of eosinophilic granulomas must be individualized and might require diagnosis through needle biopsy.

Topical ophthalmic use of cyclosporin A for Splendore-Hoeppli phenomenon.

The Splendore-Hoeppli reaction is a rare phenomenon characterised by the formation of eosinophilic material around infectious or non-infectious agents. A 33-year-old patient with persistent Splendore-Hoeppli phenomenon was previously treated with topical steroids but this resulted in a rise in intraocular pressure. The patient was treated with topical cyclosporin A one per cent twice daily as an alternative immunosuppression. After three weeks of treatment the patient had complete resolution of her conjunctival granuloma. This case report introduces cyclosporin A as a treatment option for the Splendore-Hoeppli phenomenon. This is a safe drug for long-term topical use in this condition.

Granuloma faciale: a rare disease from a dermoscopy perspective.

The granuloma faciale is a rare and benign skin disease of unknown etiology, characterized by chronic leukocitoclastic vasculitis. It is characterized by skin lesions predominantly facial whose course is chronic and slowly progressive. The diagnosis is based on clinical features, histopathology and, more recently, in dermoscopy. We describe the case of a male patient, 40 years old, with a sarcoid lesion on the malar site, whose histopathological examination revealed a mixed inflammatory infiltrate with presence of Grenz zone. Dermoscopy revealed a pink background with white striations. The definitive diagnosis is made by histopathologic evaluation, and dermatoscopy can be helpful. It is known to be resistant to therapy, oral medications, intralesional and surgical procedures are options.
