Eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome)

SUMMARY Churg-Strauss syndrome, Eosinophilic granulomatosis with polyangiitis (EGPA), is a systemic vasculitis that affects small- to medium-sized vessels. It is rare and part of the Anti-neutrophil cytoplasm antibody-associated vasculitis (ANCA) group. We present a 37-year-old man, with a previous history of asthma, that was sent to the ED due to 2 weeks of productive cough, occasional dyspnea on exertion, fever (one week), asthenia, and anorexia. Upon physical examination, he was subfebrile and tachycardic. He had leukocytosis (17.00 x10^9/L) and eosinophilia of 20.0 % (3.4 X10^9/L), creatinine level of 1.5 mg/dL, subtle elevation on liver function tests and CRP of 10.82mg/dL. On Chest X-Ray, there was infiltrate on the right pulmonary base. Due to a strong suspicion of EGPA, he was started on 80mg of prednisolone from admission. ANCA MPO was positive, with the remaining auto-immune study negative. He underwent Thorax CT (under corticotherapy) without relevant changes, as well as bronchoalveolar lavage, without macroscopic signs of alveolar hemorrhage. Because of active urinary sediment, nephrotic proteinuria (6.5g/24h), and acute renal failure he underwent a renal biopsy, which revealed pauci-immune crescentic glomerulonephritis, with predominantly acute findings (in the context of ANCA-MPO Vasculitis - EGPA). After the biopsy, he received three 1g methylprednisolone pulses and was started on Cyclophosphamide. He remained asymptomatic and renal function was restored. This case highlights the importance of integrating all findings in one clinical scenario to prevent a more complex disease diagnosis, with a specific treatment, from being missed.

RESUMO A vasculite de Churg-Strauss, granulomatose eosinofílica com poliangeíte (EGPA), é uma vasculite sistêmica que afeta vasos de pequeno e médio calibre. É rara e pertence ao grupo de vasculites associadas a anticorpos anticitoplasma de neutrófilos (Anca). Apresenta-se um homem de 37 anos, com antecedentes de asma, que recorre ao SU por tosse produtiva com dois meses de evolução, dispneia ocasional em esforço, febre (uma semana de evolução), astenia e anorexia. Ao exame objetivo apresentava-se subfebril e taquicárdico. Analiticamente com leucocitose (17,00 x10^9/L) e eosinofilia de 20,0% (3,4 X10^9/L), creatinina de 1,5 mg/dL, discreta alteração das provas de função hepática e PCR de 10,82 mg/dL. Na radiografia de tórax objetivava-se infiltrado na base pulmonar direita. Por elevada suspeita de EGPA, iniciou prednisolona 80 mg desde a admissão. Anca MPO+, com restante estudo de autoimunidade negativo. Realizou TC tórax (sob corticoterapia) sem alterações de relevo, bem como lavado bronco-alveolar, sem sinais macroscópicos de hemorragia alveolar. Por sedimento urinário ativo, proteinúria na faixa nefrótica (6,56 g/24h) e lesão renal aguda, realizou biópsia renal que revelou glomerulonefrite crescêntica pauci-imune, com achados predominantemente agudos (no contexto de Vasculite Anca-MPO - EGPA). Após biópsia, realizou três pulsos de 1 g de metilprednisolona e iniciou ainda ciclofosfamida. Ficou assintomático e com recuperação da função renal. Este caso realça a importância de integração de todos os achados num só cenário a fim de evitar que escape o diagnóstico de uma doença mais complexa e com um tratamento específico.

Se exponen las características clínicas y resultados de los exámenes complementarios realizados a un paciente del sexo masculino, de 24 años de edad, con rinitis, hemorragia pulmonar, insuficiencia renal aguda y anticuerpos anticitoplasmas de neutrófilos positivos (AU).

ABSTRACT Wegener´s disease or granulomatosis with polyangiitis is a rare disease, characterized for presenting a primary granulomatous systemic vasculitis, with affectation of the upper and lower airways and the kidneys. The authors expose clinical characteristics and the results of the complementary exams performed to a male patient, aged 24 years, with rhinitis, pulmonary hemorrhage, acute renal insufficiency, and anti-cytoplasmic antibodies of positive neutrophils (AU).

Serum 25-hydroxyvitamin D levels in patients with Granulomatosis with Polyangiitis: association with respiratory infection

OBJECTIVES: To determine the possible association of serum 25-hydroxyvitamin D (25OHD) levels with disease activity and respiratory infection in granulomatosis with polyangiitis patients during two different periods: winter/spring and summer/autumn. METHODS: Thirty-two granulomatosis with polyangiitis patients were evaluated in the winter/spring, and the same patients (except 5) were evaluated in summer/autumn (n=27). The 25OHD levels were measured by radioimmunoassay. Disease activity was assessed by the Birmingham Vasculitis Activity Score Modified for Wegener's Granulomatosis (BVAS/WG) and antineutrophil cytoplasmic antibody (ANCA) positivity. Respiratory infection was defined according the Centers for Disease Control and Prevention criteria. RESULTS: 25OHD levels were lower among patients in winter/spring than in summer/autumn (32.31±13.10 vs. 38.98±10.97 ng/mL, p=0.04). Seven patients met the criteria for respiratory infection: 5 in winter/spring and 2 in summer/autumn. Patients with respiratory infection presented lower 25OHD levels than those without infection (25.15±11.70 vs. 36.73±12.08 ng/mL, p=0.02). A higher frequency of low vitamin D levels (25OHD<20 ng/mL) was observed in patients with respiratory infection (37.5% vs. 7.8, p=0.04). Serum 25OHD levels were comparable between patients with (BVAS/WG≥1 plus positive ANCA) and without disease activity (BVAS/WG=0 plus negative ANCA) (35.40±11.48 vs. 35.34±13.13 ng/mL, p=0.98). CONCLUSIONS: Lower 25OHD levels were associated with respiratory infection but not disease activity in granulomatosis with polyangiitis patients. Our data suggest that hypovitaminosis D could be an important risk factor for respiratory infection in granulomatosis with polyangiitis patients.

Association between Wegener´s granulomatosis and severe lumbar pain

Introducción: La granulomatosis de Wegener (GW) es una enfermedad autoinmune sistémica caracterizada por vasculitis granulomatosa necrotizante que afecta principalmente a las vías respiratorias superiores, pulmones y riñones. Sin embargo, con menos frecuencia puede afectar a los músculos, las articulaciones, la piel, los ojos, el sistema cardiovascular y el sistema nervioso. La presencia de dolor lumbar consiste en una manifestación clínica inusual debido a la afectación del sistema nervioso. Objetivo: El objetivo de este estudio es alertar a los profesionales de la salud acerca de la posibilidad de cortar el dolor lumbar estar relacionado con la granulomatosis de Wegener, su impacto en la vida diaria del paciente, así como los signos clínicos y las formas de diagnóstico.

Introduction: Wegener’s granulomatosis (WG) is a systemic autoimmune disease characterized by necrotizing granulomatousvasculitis which primarily affects upper respiratory tract, lungs and kidneys. However, less frequently can affect muscles,joints, skin, eyes, cardiovascular system and nervous system. The presence of lumbar pain consists in an unusual clinicalmanifestation due to the involvement of the nervous system. Objective: The objective of this study is to alert health professionalsabout the possibility that severe lumbar pain be related to Wegener’s granulomatosis, it’s impact on the patient’s dailylife as well as clinical signs and diagnosis forms. Materials and Methods: Literature review using PubMed, MEDLINE, GoogleScholar, SciELO, EBSCO. Selected works from 1995 to 2013 totaling 48 works of which 21 were selected according to theirreports of neurological involvement, diagnosis and treatment. Discussion: Neurological symptoms may occur in 22-50 percent of patients during the course of WG. Central nervous system (CNS) involvement is uncommon (only 2-8 percent of patients).Severelumbar pain is a rare clinic manifestation and it can be associated with the involvement of central and peripheral nervous system.CNS due to compression of the spinal cord at the lumbar level. Peripheral nervous system due to compression of nerveroots. Conclusion: Wegener’s granulomatosis for being a systemic disease can present different clinical manifestations accordingto the involved site. It’s associations with lumbar pain is rare and reflects it’s neurological involvement. Therefore, inpatients with severe lumbar pain without confirmed diagnosis, Wegener’s granulomatosis should be considered.

Granulomatosis con poliangeítis de presentación atípica: revisión de la literatura a propósito de un caso de localización ginecológica / Cervicovaginal granuloma as the first manifestation of granulomatosis with polyangiitis

La granulomatosis con poliangeitis (GPA) es una vasculitis sistémica, granulomatosa, con compromiso de pequeños vasos y presencia de anticuerpos c-ANCA. Ocasionalmente es localizada y es rara su manifestación genitourinaria. Se presenta el caso de una mujer de 68 años con sangrado genital causado por una lesión cervicovaginal verrucosa ulcerada, cuya histopatología descartó malignidad, hongos y TBC, con mala respuesta a antibióticos, ácido tricloro acético y crioterapia. Por recidiva al año se practica histerectomía total y colpectomía parcial, pero reincide al mes acompañada de epistaxis, cuyo estudio pornasofibroscopía e imágenes concluye en una lesión de tipo granulomatosa, agregándose anticuerpo anti PR-3 positivo. Se diagnostica GPA y se trata con ciclofosfamida con buena respuesta. La revisión de la literatura permite concluir que la GPA con localización cervicovaginal es muy poco frecuente, especialmente como manifestación inicial, y se debe considerar en el diagnóstico diferencial con cáncer y otras lesiones granulomatosas localizadas.

Granulomatosis with polyangiitis (GPA) is a systemic vasculitis, granulomatous, with commitment of small vessels and the presence of c-ANCA antibodies. Occasionally it is located and its genitourinary manifestation is rare. Presented the case of a 68 year old woman with genital bleeding caused by a lesion cervicovaginal ulcerated verrucosa, whose histopathology ruled out fungal, malignancy and TBC, with poor response to antibiotics, acid trichloro acetic and cryotherapy. By relapse a year is practiced total hysterectomy and partial colpectomia, but repeated a month accompanied by epistaxis, whose study by nasofibroscopia and images concludes in a type granulomatous lesion, adding antibody anti PR-3 positive. GPA is diagnosed and treated with cyclophosphamide with good response. Review of the literature leads to th conclusion that the GPA with cervico-vaginal location is very rare, especially as an initial manifestation, and should be considered in the diagnosis diferenttial with cancer and other localized granulomatous lesions.

Granulomatosis with polyangiitis, a new nomenclature for Wegener's Granulomatosis - Case report

The granulomatosis with polyangiitis, initially known as Wegener's granulomatosis, is a small and medium vessels vasculitis. It's classic form presents a triad: necrotizing granuloma of respiratory tract, necrotizing cutaneous vasculitis and glomerulonephritis. This vasculitis has cytoplasmic antineutrophil antibodies as signal. This work illustrates a case, of multisystemic rare disease, in which the segment and treatment were considered satisfactory for symptoms remission.

Nodular scleritis and granulomatous polyangiitis (Wegener) mimicking tuberculosis / Esclerite nodular e poliangiite granulomatosa (Wegener) mimetizando tuberculose

Granulomatous polyangiitis is a systemic disease that may affect any organ, with a predilection for the upper respiratory tract, lungs and kidneys. This article aims to report a case of a patient with atypical nodular scleritis as the initial manifestation of granulomatous polyangiitis (Wegener), mimicking a case of tuberculosis. The patient presented ocular hyperemia and lower progressive visual acuity for 1.5 years, followed by eye pain for two months. The patient had subpleural nodules with soft tissue density, increased pulmonary lymph nodes and discrete bilateral pleural thickening, with negative alcohol-resistant acid bacilli (BAAR). The histological diagnosis revealed a granulomatous vasculitis suggestive of non-infectious vasculitis (granulomatous polyangiitis). Cyclophosphamide pulse therapy was initiated.

Poliangiite granulomatosa é uma doença sistêmica que afeta qualquer órgão, com predileção pelo trato respiratório superior, pulmões e rins. Este artigo tem como objetivo relatar um caso atípico de uma paciente com esclerite nodular como manifestação inicial da poliangiite granulomatosa (Wegener), mimetizando um quadro de tuberculose. A paciente apresentou hiperemia ocular e baixa acuidade visual progressiva por 1,5 anos, seguido por dor ocular por dois meses. A paciente possuía nódulos subpleurais com densidade de partes moles, linfonodomegalia em janela aorto-pulmonar e espessamento pleural bilateral discreto, negativo para bacilos álcool-ácido resistentes (BAAR). O diagnóstico histológico revelou uma vasculite granulomatosa sugestiva de vasculite não infecciosa (poliangiite granulomatosa). Foi iniciada pulsoterapia com ciclofosfamida.

Granulomatosis eosinofílica con poliangeítis: reporte de caso yrevisión de la literatura / Eosinophilic granulomatosis with polyangiitis: case report and review of the literature

La granulomatosis eosinofílica con poliangeítis (Síndrome de Churg-Strauss) es una enfermedad vasculítica primaria poco frecuente. El diagnóstico actualmente se define a partir de la presencia de al menos cuatro de seis criterios propuestos por la Sociedad Americana de Reumatología, los cuales incluyen: asma bronquial, eosinofilia mayor que 10 por ciento, sinusitis paranasal, infiltración pulmonar, evidencia histológica de vasculitis y compromiso neurológico ya sea mono o polineuropático. En el presente artículo se reporta el caso de un paciente de 56 años con antecedentes de asma bronquial, rinitis alérgica y poliposis nasal operada, derivado a nuestro centro por cuadro de aumento de volumen doloroso en ambas extremidades inferiores, baja de peso, parestesias y debilidad muscular. Asociado a esto desarrolló lesiones purpúricas palpables cuya biopsia resultó compatible con granulomatosis eosinofílica con poliangeítis. El paciente posteriormente recibió tratamiento inmunosupresor con prednisona y un pulso de ciclofosfamida con buena respuesta clínica. Se presenta una revisión bibliográfica a propósito del caso.

Eosinophilic granulomatosis with polyangiitis (Churg-Strauss Syndrome) is an uncommon primary vasculitis. The diagnosis is currently defined by the presence of at least four of six criteria proposed by the American College of Rheumatology, which include: asthma, eosinophilia less than 10 percent, paranasal sinusitis, pulmonary infiltration, histologic evidence of vasculitis and neurologic compromise as mono or polyneuropathy. In the present article, we report the case of a 56 year-old man with history of asthma, allergic rhinitis and operated nasal polyposis, referred to our center with painful bulking in both lower extremities, weight loss, paresthesias and muscle weakness. It also developed palpable purpura. Biopsy of skin lesions was compatible with eosinophilic granulomatosis with polyangiitis. The patient subsequently received immunosuppressive therapy with prednisone and a cyclophosphamide bolus with good clinical response. A review on the subject is also presented.

Vasculitis asociadas a anticuerpos anti-citoplasma de neutrófilos: Clínica y tratamiento / Anti-neutrophil cytoplasmic antibody-associated vasculitis: Clinical aspects and treatment

Las vasculitis asociadas a anticuerpos anti-citoplasma de neutrófilos (ANCA) comprenden a un grupo de enfermedades caracterizadas por la inflamación de la pared de pequeños vasos. Analizamos las características epidemiológicas y clínicas en una serie de 47 pacientes: 23 (49%) granulomatosis de Wegener (GW), 15 (32%) poliangeítis microscópica (PAM) y nueve (19%) vasculitis limitada al riñón (VLR). La edad media al inicio de los síntomas fue de 50.7 ± 14.9 años. La manifestación clínica más frecuente fue el compromiso renal en 41 (87%) pacientes, seguido por el pulmonar en 26 (55%) y el otorrinolaringológico en 17 (36%). En 26 (55%) se asoció compromiso renal y pulmonar. La forma clínica más frecuente fue la generalizada en 23 (49%), seguida por la grave en 18 (38%). El 89% presentaron determinaciones de ANCA positivas. Cuatro (8%) no recibieron tratamiento inmunosupresor de inicio. De los 43 que recibieron tratamiento de inicio, 29 (67%) tuvieron remisión completa, con un tiempo de remisión promedio de 35.3 meses. Once (26%) presentaron recaídas, diez (91%) recaídas mayores y uno (9%) menor. Doce (28%) fallecieron, siete en forma temprana y cinco durante la evolución de la enfermedad. Quince (31%) evolucionaron a insuficiencia renal crónica. Los 26 pacientes en seguimiento tuvieron respuesta al tratamiento y 20 (77%) de ellos estaban en remisión al finalizar el estudio. Las vasculitis asociadas a ANCA continúan siendo enfermedades de alta morbilidad y mortalidad, a pesar de las mejorías logradas con los tratamientos inmunosupresores.

Anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis, comprise a group of diseases characterized by inflammation of the wall of small vessels. We analyzed epidemiological and clinical characteristics in a series of 47 patients, 23 (49%) with Wegener granulomatosis (WG), 15 (32%) with microscopic polyangiitis (MPA) and nine (19%) with renal limited vasculitis (RLV). The mean age at onset of symptoms was 50.7 ± 14.9 years. The most frequent clinical manifestation was renal involvement in 41 (87%), followed by pulmonary manifestations in 26 (55%) and ENT involvement in 17 (36%). In 26 (55%) it presented with simultaneous pulmonary and renal involvement. The most frequent clinical category was the generalized form in 23 (49%), followed by the severe form in 18 (38%). Eighty nine percent of patients had positive ANCA test. Four (8%) received no immunosuppressive treatment. Of the 43 patients who were treated, 29 (67%) achieved complete remission with an average length of remission of 35.3 months. Eleven (26%) had a relapse, ten (91%) had a major relapse and one had a minor relapse. Twelve (28%) patients died, seven died early and five late during the course of the disease. Fifteen (31%) progressed to chronic renal failure. All 26 patients in follow-up had response to treatment and 20 (77%) were in remission at the end of the study. Despite the improvements achieved with immunosuppressive treatments, morbidity and mortality rates in ANCA-associated vasculitis remain high.

Atualização do tratamento das vasculites associadas a anticorpo anticitoplasma de neutrófilos / Treatment of antineutrophil cytoplasmic antibody-associated vasculitis: update

As vasculites antineutrophil cytoplasmic antibody (ANCA, anticorpo anticitoplasma de neutrófilos) associadas (VAAs) são caracterizadas por uma inflamação sistêmica das artérias de pequeno e médio calibre (especialmente no trato respiratório superior e inferior, e nos rins). As VAAs compreendem a granulomatose de Wegener (agora chamada de granulomatose com poliangeíte), poliangeíte microscópica, VAA limitada ao rim e a síndrome de Churg-Strauss. Neste artigo, discutiremos as fases de tratamento dessas vasculites, como fase de indução (com ciclofosfamida ou rituximab) e fase de manutenção (com azatioprina, metotrexato ou rituximab). Além disso, discutiremos como manusear os casos refratários à ciclofosfamida.

In its various forms, antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is characterized by a systemic inflammation of the small and medium-sized arteries (especially in the upper and lower respiratory tracts, as well as in the kidneys). The forms of AAV comprise Wegener's granulomatosis (now called granulomatosis with polyangiitis), microscopic polyangiitis, renal AAV, and Churg-Strauss syndrome. In this paper, we discuss the phases of AAV treatment, including the induction phase (with cyclophosphamide or rituximab) and the maintenance phase (with azathioprine, methotrexate, or rituximab). We also discuss how to handle patients who are refractory to cyclophosphamide.

Granulomatosis de Wegener, abordaje diagnóstico y terapéutico / Wegener's granulomatosis: diagnosis and treatment

La granulomatosis de Wegener es una vasculitis sistémica, necrosante y granulomatosa que afecta el tracto respiratorio superior e inferior y el riñón; es la vasculitis anticuerpos anticitoplasma del neutrófilo (ANCA) positiva más frecuente. El diagnóstico se basa en las manifestaciones clínicas, la biopsia de los órganos afectados y la presencia de ANCA en el suero. Los criterios de clasificación según el Colegio Americano de Reumatología son inflamación oral o nasal, alteraciones en la radiografía de tórax (nódulos, infiltrado pulmonar fijo, cavitaciones), anormalidades urinarias (hematuria), biopsia con infiltrado granulomatoso. El tratamiento se divide en dos fases: de inducción a la remisión y de mantenimiento. En la primera es necesario el uso de terapia inmunosupresora intensiva: ciclofosfamida más esteroides para controlar la actividad de la enfermedad (tres a seis meses). En la fase de mantenimiento, menos intensa, se emplean inmunosupresores como azatioprina, metotrexate, micofenolato de mofetilo, entre otros; su objetivo es mantener la remisión y disminuir los efectos adversos asociados a la ciclofosfamida. El etanercept no ha sido útil para la fase de mantenimiento. El rituximab y la 15-desoxipergualina son terapias alternativas en casos refractarios.

Wegener's granulomatosis (WG) is a systemic, necrotizing and granulomatous vasculitis that affects the upper and lower respiratory tract and the kidney. It is the most common antineutrophil cytoplasmic antibodies (ANCA) vasculitis. The diagnosis of WG is based on clinical manifestations, histological findings and the presence of ANCA in serum. The American College of Rheumatology criteria includes: oral and nasal inflammation, abnormal chest radiography (nodules, fixed infiltrates, or cavities, urinary sediment (hematuria), and granulomatous inflammation on biopsy. Treatment of WG is divided into 2 phases, induction of remission (IR), followed by a maintenance phase (MP). In the IR it is necessary to use immunosuppressive intensive therapy (cyclophosphamide plus steroids) and the MP is a less intensive therapy in which immunosuppressors (IS) such as azathioprine, methotrexate, mycophenolate of mofetil, among others, may be employed. Their purpose is to keep remission and lower the adverse effects associated with IS. Etanercept has not been proven successfully for the MP. Rituximab and 15-dexopergualin constitute promising the rapies for refractory WG.

Wegener granulomatosis; diagnosis and management

To highlight the different clinical features, parameters of diagnosis and to see the effect of chemotherapy and steroids on this disease. Department of Otolaryngology Head and Neck Surgery Jinnah Hospital Lahore. From Dec 1998 to July 2001. Five cases of Wegener Granulomatosis were studied during the study period. Three patients had limited disease while two patients had generalized disease with renal involvement. All patients were started on azathiopurine [2mg/Kg/day] orcyclophoshamide [1-2mg/kg/day] along with steroids. After a months time the dose of steroid was reduced to alternate day. Weekly monitoring of white blood cell count with urine examination for RBCs or protein casts was done. Any patient with haematuria or TLC reduced to less than 3500 were immediately taken off from cyclophosphamide and azathiopurine was started. Patients having classic disease, dose of cyclophoshamide had to be increased from two to four milligram / per Kilogram per day to achieve a good response. The response to treatment was measured by noticing the resolution of pulmonary infiltrates reduced ESR and negative C-ANCA. We found nasal symptoms like nasal obstruction and epistaxis to be the most common symptom followed by fever, cough and deafness. Crusting, granulations and occasional perforation were usually found on nasal examination. Conductive deafness was most common ear finding. History, clinical examination, ESR, C-ANCA and a representative biopsy were all essential in diagnosing this condition. Azathiopurine and cyclophosphamide were the main chemotherapeutic agents used with prednisone to cause remission in all our patients except one who died two weeks after having been admitted in our institution. Surprisingly in contrast to the normal cause of high mortality reported in international literature in this disease to be renal failure, our patient died due to respiratory failure. Four out of five patients went into remission a year after regular treatment with this regime. The major complications occurring during hospital stay and their treatment were nausea, vomiting, sudden fall of TLC, and oral thrush. The common presentation of patient with Wegner's Granulomatosis is of upper respiratory tract symptoms like nasal obstruction and epistaxis followed by lower respiratory symptoms like cough, fever and Haemoptysis. A representative biopsy with positive C-ANCA and high ESR are hallmarks of diagnosing this condition. The most effective medical regime till today is cyclophosphamide and azathiopurine with alternate day prednisone for inducing remission

Diagnóstico de granulomatosis de Wegener en pacientes con enfermedades oculares inflamatorias / Diagnosis of Wegener's granulomatosis in patients with ocular inflamatory disease

Objetivo. Informar las manifestaciones oftalmológicas en pacientes con granulomatosis de Wegener (GW). Método. Se revisó la base de datos del Instituto de Oftalmología Conde de Valenciana. Se recolectó la exploración oftalmológica completa, los exámenes de laboratorio y de gabinete, el tratamiento y la evolución. Resultados. Se incluyeron 11 pacientes con GW (18 ojos). Siete pacientes masculinos y 4 femeninos con edad promedio de 43.7 años (28-55). Tres habían tenido diagnóstico previo de GW y los 8 restantes se diagnosticaron en nuestro departamento. Siete presentaron cuadros bilaterales y 4 unilaterales. Las formas de presentación clínica fueron escleritis necrosante con queratitis ulcerativa periférica (QUP) (7/18), escleritis difusa (3/18), escleritis nodular (1/18), uveítis anterior no granulomatosa (1/18), neuropatía óptica isquémica (1/18), neuropatía óptica retrobulbar (1/18), desprendimiento de retina seroso (2/18) y dacriocistitis (2/18). De los 18 ojos, la capacidad visual final fue mejor o igual a 20/40 en 13, 20/400 en 3, cuenta dedos a 30cm o no-percepción de luz en 1. Actualmente 7 pacientes se encuentran en fase inactiva. Conclusiones. Las manifestaciones oftalmológicas más frecuentes en pacientes con GW fueron: escleritis necrosante y QUP. En la mayoría, la GW se diagnosticó después de las manifestaciones oftalmológicas, sin embargo, todos presentaron síntomas sistémicos u oftalmológicos previos.

OBJECTIVE: Report the ophthalmologic manifestations among patients with Wegener 's Granulomatosis (WG). METHOD: We reviewed the database of the Instituto de Oftalmologia Fundación Conde de Valenciana in order to collect information regarding complete ophthalmic examination, laboratory and cabinet tests, treatment, and disease progression. RESULTS: We included 11 patients with WG (18 eyes). Seven men and four women, mean age 43.7 years (range = 28-55). Three patients had a prior diagnosis of WG and the remaining eight patients were diagnosed by our study team. Seven subjects developed a bilateral affection and four had unilateral involvement. The clinical presentation was necrotizing scleritis with peripheral ulcerative keratitis (PUK) (7/18), diffuse scleritis (3/18), nodular scleritis (1/18), non-granulomatous uveitis (1/18), optic ischemic neuropathy (1/18), retrobulbar neuritis (1/18), serous retinal detachment (2/18), and dacryocystitis (2/18). Final visual acuity was better or equal to 20/40 (13/18), 20/400 (3/18), finger-counting or no-perception of light in 1/18. Currently, seven patients are symptom free. CONCLUSIONS: The most frequent ophthalmic manifestations among our patients with WG were: necrotizing scleritis and PUK. In most cases, WG was diagnosed after ophthalmic manifestations; however, all patients displayed prior systemic or ocular symptoms.

Wegener's granulomatosis: a case reports

Wegener's Granulomatosis is a rare disorder, presenting with granulomatous vasculitic lesions, mainly involving the respiratory tract [including the lungs] and associated with glomerulonephritis. We present the case of a 33-year old male patient who was admitted with complaints of cough and hemoptysis associated with vasculitic skin lesions. He had high levels of serum cytoplasmica ntineutrophil cytoplasmic antibody [C-ANCA]. The chest X-ray revealed extensive infiltrates in both lung fields. As the patient was too ill on account of severe hypoxia, lung biopsy could not be carried out, but skin biopsy revealed leukocytoclastic vasculitis. Based on these findings, a clinical diagnosis of We gener' s granulomatosis was made and combined therapy of steroids and cyclophosphamide started. The patient showed dramatic improvement and recovered fully from this life threatening condition

Clinicopathologic study of Wegener's granulomatosis with special emphasis on early lesions in 10 Korean patients

We reviewed ten cases of Wegener's granulomatosis with special emphasis on the characteristics of the early stage of Wegener's granulomatosis. All patients presented with nonspecific symptoms and signs, so that Wegener's granulomatosis was not initially considered. However, half of the patients had clinical or radiologic disease in the nose/or paranasal sinuses as the primary presenting problems and showed neutrophil microabscess surrounded by palisading epithelioid cells and irregularly arranged giant cells in the nasal biopsy as the most characteristic feature. Five of ten patients were believed to have a protracted superficial phenomenon before involvement of other organs, specifically the lung or kidney. Four of ten patients showed nonreactivity to ANCA test at the time of presentation. Although the number of cases reviewed in this study was small, the rate of nonreactivity to ANCA was higher than those of the larger series. The importance of early diagnosis of Wegener's granulomatosis can not be overemphasized in view of the fact that cases unrecognized clinicopathologically finally progress to full-blown systemic form of Wegener's granulomatosis with poor prognosis. The diagnosis of Wegener's granulomatosis should be based on a thorough and meticulous examination of its characteristic histologic changes in biopsied tissue particularly extravascular foci.
