RESUMO
INTRODUCTION: Granulomatosis with polyangiitis (GPA) is rare but debilitating autoimmune disease and commonly presents with sinonasal as well as other head and neck symptoms. AIMS: To summarize the ear, nose, and throat-specific symptomatology and management of GPA. METHODS AND RESULTS: We performed a literature review by using the PubMed search engine to provide a summary of recent and important literature that is pertinent to an otolaryngologist's clinical practice. We provide a guide on the pathophysiology, epidemiology, clinical features, investigation, and management (operative and nonoperative) of this important disease. CONCLUSIONS: This review illustrates the important role that an otolaryngologist can play in the work up and symptom management of patients with GPA. Knowledge of the common presenting symptoms as well as more rare presentations of GPA is extremely important for otolaryngologists as prompt diagnosis and management is extremely important to avoid significant morbidity and mortality.

Proteinase 3 (PR3)-specific antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is one of two major ANCA-associated vasculitis variants and is pathogenically linked to granulomatosis with polyangiitis (GPA). GPA is characterised by necrotising granulomatous inflammation that preferentially affects the respiratory tract. The small vessel vasculitis features of GPA are shared with microscopic polyangiitis. Necrotising granulomatous inflammation of GPA can lead to PR3-ANCA and small vessel vasculitis via activation of neutrophils and monocytes. B cells are central to the pathogenesis of PR3-ANCA-associated vasculitis. They are targeted successfully by remission induction and maintenance therapy with rituximab. Relapses of PR3-ANCA-associated vasculitis and toxicities associated with current standard therapy contribute substantially to remaining mortality and damage-associated morbidity. More effective and less toxic treatments are sought to address this unmet need. Advances with cellular and novel antigen-specific immunotherapies hold promise for application in autoimmune disease, including PR3-ANCA-associated vasculitis. This Series paper describes the inter-related histopathological and clinical features, pathophysiology, as well as current and future targeted treatments for PR3-ANCA-associated vasculitis.

OBJECTIVES: Prospective long-term observational data on the disease course of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) were missing in Germany to date. Therefore, the Joint Vasculitis Registry in German-speaking countries (GeVas) has been established to follow the course of patients with AAV. The aim of this study is to present baseline data of patients with newly diagnosed and relapsing AAV enrolled in the GeVas registry. METHODS: GeVas is a prospective, web-based, multicentre, clinician-driven registry for the documentation of organ manifestations, damage, long-term outcomes, and therapy regimens in various types of vasculitis. Recruitment started in June 2019. RESULTS: Between June 2019 and October 2022, 266 patients with AAV were included in the GeVas registry: 173 (65%) with new-onset and 93 (35%) with relapsing AAV. One hundred and sixty-two (61%) patients were classified as granulomatosis with polyangiitis (GPA), 66 (25%) as microscopic polyangiitis (MPA), 36 (13%) as eosinophilic granulomatosis with polyangiitis (EGPA), and 2 (1%) as renal limited AAV. The median age was 59 years (51-70 years, IQR), 130 (51%) patients were female. Most patients were ANCA positive (177; 67%) and affected by general symptoms, pulmonary, ear nose throat (ENT), renal and neurological involvement. For induction of remission, the majority of patients received glucocorticoids (247, 93%) in combination with either rituximab (118, 45%) or cyclophosphamide (112, 42%). CONCLUSIONS: Demographic characteristics are comparable to those in other European countries. Differences were found regarding ANCA status, frequencies of organ manifestations, and therapeutic regimens. The GeVas registry will allow longitudinal observations and prospective outcome measures in AAV.

OBJECTIVES: To investigate the epidemiological features of granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA) in South Korea. METHODS: We identified the index cases of GPA and MPA using the 2010-2018 Korean National Health Insurance Service database and the Rare Intractable Disease registry for the entire Korean population. Each disease's incidence and prevalence rates and trends over time were analysed. To assess the impact of disease on morbidity and mortality, a comparator group comprising the general population was established using nearest-neighbour matching by age, sex, income, and comorbidity index, at a 5:1 ratio. Morbidity outcomes included the initiation of renal replacement therapy and admission to the intensive care unit. RESULTS: We identified 546 and 795 patients with GPA and MPA, respectively. The incidence rates of both diseases increased with age, with peak incidence rates observed among patients aged ≥70 years. The incidence of MPA increased continuously over time, whereas that of GPA showed no significant changes. During the observation period, 132 (28.7%) and 277 (41.1%) patients in the GPA and MPA groups, respectively, died, which were significantly higher than that in the general population (standardised mortality ratio: 3.53 and 5.58, respectively) and comparator group (hazard ratio: 4.02 and 5.64, respectively). Higher mortality and morbidity rates were observed among patients with MPA than among those with GPA. CONCLUSIONS: In South Korea, the incidence of MPA has increased over time. Although both GPA and MPA had high rates of mortality and morbidity, MPA has a poorer prognosis than GPA.

RESUMO A granulomatose com poliangiíte é um raro distúrbio inflamatório sistêmico que se caracteriza por vasculite de pequenas artérias, arteríolas e capilares, associada a lesões granulomatosas necrotizantes. Este artigo relata o caso de uma paciente com diagnóstico prévio de granulomatose com poliangiíte, admitida à unidade de terapia intensiva com quadro de crises convulsivas e instabilidade hemodinâmica em razão de bloqueio atrioventricular completo. Estas manifestações se associaram a múltiplos episódios de taquicardia ventricular sustentada; não havia alterações estruturais cardíacas, nem se detectaram distúrbios hidroeletrolíticos. Na unidade de terapia intensiva, a paciente foi submetida à implantação de marca-passo provisório, imunossupressão com uso de corticosteroides e terapia imunobiológica, resultando em melhora hemodinâmica completa. Distúrbios graves da condução cardíaca em pacientes com granulomatose com poliangiíte são raros, mas associam-se à grande morbidade. O reconhecimento precoce e o uso de intervenções específicas são capazes de prevenir a ocorrência de desfechos desfavoráveis, especialmente na unidade de terapia intensiva.
ABSTRACT Granulomatosis with polyangiitis is a rare systemic inflammatory disorder characterized by vasculitis of the small arteries, the arterioles and the capillaries together with necrotizing granulomatous lesions. This case reports on a young female patient, previously diagnosed with granulomatosis with polyangiitis, who was admitted to the intensive care unit with seizures and hemodynamic instability due to a complete atrioventricular heart block. The event was associated with multiple episodes of sustained ventricular tachycardia without any structural heart changes or electrolyte disturbances. In the intensive care unit, the patient was fitted with a provisory pacemaker, followed by immunosuppression with corticosteroids and immunobiological therapy, resulting in a total hemodynamic improvement. Severe conduction disorders in patients presenting granulomatosis with polyangiitis are rare but can contribute to increased morbidity. Early detection and specific intervention can prevent unfavorable outcomes, specifically in the intensive care unit.

Introducción. La granulomatosis con poliangeítis (GP) es una vasculitis necrosante de causa desconocida, que afecta a vasos de mediano y pequeño calibre. Se asocia a anticuerpos anticitoplasma de neutrófilo (ANCA). Afecta con más frecuencia a los aparatos respiratorio y renal, y la característica anatomopatológica más relevante es la presencia de granulomas necrosantes. Objetivos. Detallar las características de una serie de 15 pacientes con GP diagnosticados en un centro universitario de referencia. Pacientes y métodos. Diseño retrospectivo: entre 1984 y 2009 se diagnosticaron 15 pacientes con GP en nuestro centro. De todos ellos se obtuvieron de forma retrospectiva datos epidemiológicos, clínicos, analíticos, estudios anatomopatológicos y tratamiento recibido. Se consideró criterio de inclusión la biopsia diagnóstica de GP. Resultados. Se diagnosticaron de GP 15 pacientes: 12 varones y 3 mujeres. Edad media en el momento del diagnóstico: 52,2 años (14-78). Antecedente de tabaquismo: 12 pacientes. Se practicó una biopsia que fue diagnóstica en todos los pacientes. Los ANCA resultaron positivos en 11 casos, y de éstos 6 correspondían a un patrón citoplasmático c-ANCA. Todos los pacientes tuvieron afectación pulmonar y siete (46%) tuvieron afectación renal. Todos los pacientes recibieron como tratamiento de inducción glucocorticoides endovenosos y ciclofosfamida. Cinco han fallecido. Conclusiones. Las características clínicas de la presente serie no difieren de las descritas por otros autores. El antecedente de tabaquismo fue más frecuente de lo esperado. Los fármacos más utilizados fueron los glucocorticoides y la ciclofosfamida (oral y en emboladas). La evolución generalmente fue desfavorable, con brotes o complicaciones debidas al estado de inmunosupresión, con excepción de las formas localizadas. Es preciso mantener el tratamiento inmunosupresor de forma indefinida en la mayoría de los casos (AU)
Background. Granulomatosis with polyangiitis (GP) is a necrotizing vasculitis of unknown etiology that involves small and medium caliber vessels. It is associated with anti neutrophil cytoplasm antibodies (ANCA). It most often affects the respiratory tract and the kidneys and its most important pathologic feature is the presence of necrotizing granulomas. Objectives. To detail the features of 15 patients with GP diagnosed in a university referral center. Patients and methods. Retrospective study: between 1984 and 2009, 15 patients with GP were diagnosed in our center. Epidemiological, clinical, laboratory test as well as pathologic studies and treatment were retrospectively analyzed. Biopsy diagnosis of GP was considered as an inclusion criterion. Results. Fifteen patients were diagnosed: 12 men and 3 women. Mean age at diagnosis: 52.2 years (14-78). 12 patients had a history of smoking. A biopsy was diagnostic in all patients. ANCA were positive in 11 cases, 6 had a cytoplasmic c-ANCA pattern. All patients had pulmonary involvement and seven (40%) had renal involvement. All patients received intravenous glucocorticoids and cyclophosphamide as induction therapy. During the disease progression 5 patients died. Conclusions. The clinical features of this series do not differ from those described by other authors. However, a history of smoking is more common than expected. Frequently used drugs were glucocorticoids and cyclophosphamide (oral and pulse therapy). The course was usually unfavorable, with outbreaks or complications due to immunosuppression, except for those with limited forms. Immunosuppressive therapy should be maintained indefinitely in most cases (AU)

Las primeras manifestaciones de algunas vasculitis ocurren en órganos de la cabeza y el cuello; sin embargo, pocos especialistas las diagnostican en forma temprana ya que las infecciones y la alergia son más comunes. Entre ellas, signos y síntomas como epistaxis, obstrucción nasal, rinorrea serosanguinolenta, dolor ardoroso en región nasosinusal, cefalea, pólipos e incluso costras nasales, pueden encontrarse en personas que viven en ciudades con altos índices de contaminación y baja humedad, en pacientes con infecciones como el escleroma respiratorio, en aquellos sometidos a radioterapia y como consecuencia de otras condiciones; sin embargo, bajo las costras pueden crecer microorganismos como Staphylococcus aureus y también pueden hallarse señales que se pueden relacionar con vasculitis activa. El otorrinolaringólogo es uno de los primeros médicos a los que acuden pacientes con estos signos y síntomas, por lo que reconocer estas manifestaciones e integrar diagnósticos más oportunos en colaboración con otros especialistas es importante. Debido a la frecuencia con la que presentan como primeros signos y síntomas los otorrinolaringológicos, seleccionamos tres enfermedades vasculíticas para este artículo: granulomatosis con poliangitis (Wegener), el síndrome de Churg Strauss y la policondritis recurrente (AU)
First manifestations of vasculitis can appear on the head and neck, still few physicians are aware of these diseases, as they are unspecific and because other conditions like infections and allergies are more frequent. Among them, signs and symptoms like epistaxis, nasal obstruction, discharge, burning pain of sinonasal region, headache, sinus polyps and crusts, the latter found in people who live in highly polluted cities with low humidity, in patients with respiratory scleroma, atrophy, those receiving local radiotherapy, and due to other conditions. Under the crusts, many infectious agents, like Staphylococcus aureus may grow and, in addition, other signs related to active vasculitis may be found. The ENT specialist is one of the first physicians visited by patients with these signs and symptoms. Their recognition is important to readily diagnose these diseases. We have selected three vasculitidies for discussion in this paper: granulomatosis with polyangiitis (Wegener), Chrug-Strauss syndrome and relapsing polychondritis, since these three diseases present initial ENT problems with high frequency (AU)
