Objectives: The relationship between saddle nose deformity (SND) in Wegener`s granulomatosis (WG) and other clinical features, including retro-orbital mass formation (ROM), has been poor described. Therefore, this relationship was analyzed retrospectively from 2000 to 2010. Patients and Methods: Eighteen consecutive WG patients with SND diagnosed by computed tomography were matched to 36 WG patients without SND (control group) for gender, age at WG diagnosis and disease duration. Results: No difference was found between the two groups in relation to WG type (limited and systemic forms), ethnicity, laboratory features, constitutional symptoms or clinical manifestations, including upper respiratory tract, and treatment, except for ROM (33.3 vs. 2.8% in SND(+) and SND(-) groups, respectively; p=0.004) and subglottic stenosis (22.2 vs. 2.8%; p=0.038). However, on multivariate analysis, only ROM (OR 17.15; 95% CI 1.11-265.52) was statistically associated to SND. In addition, in more than half of the cases, SND manifested prior to ROM. Conclusions: Results of this prospective analysis showed that SND was strongly associated to ROM in WG. Since early diagnosis and aggressive treatment of orbital involvement could lead to better prognosis, the presence of SND warrants additional vigilance.

Objectives To validate the previously proposed classification criteria for Henoch-Schonlein purpura (HSP), childhood polyarteritis nodosa (c-PAN), c-Wegener granulomatosis (c-WG) and c-Takayasu arteritis (c-TA). Methods Step 1: retrospective/prospective webdata collection for children with HSP, c-PAN, c-WG and c-TA with age at diagnosis <= 18 years. Step 2: blinded classification by consensus panel of a representative sample of 280 cases. Step 3: statistical (sensitivity, specificity, area under the curve and.-agreement) and nominal group technique consensus evaluations. Results 827 patients with HSP, 150 with c-PAN, 60 with c-WG, 87 with c-TA and 52 with c-other were compared with each other. A patient was classified as HSP in the presence of purpura or petechiae (mandatory) with lower limb predominance plus one of four criteria: (1) abdominal pain; (2) histopathology (IgA); (3) arthritis or arthralgia; (4) renal involvement. Classification of c-PAN required a systemic inflammatory disease with evidence of necrotising vasculitis OR angiographic abnormalities of medium-/small-sized arteries (mandatory criterion) plus one of five criteria: (1) skin involvement; (2) myalgia/muscle tenderness; (3) hypertension; (4) peripheral neuropathy; (5) renal involvement. Classification of c-WG required three of six criteria: (1) histopathological evidence of granulomatous inflammation; (2) upper airway involvement; (3) laryngo-tracheo-bronchial involvement; (4) pulmonary involvement (x-ray/CT); (5) antineutrophilic cytoplasmic antibody positivity; (6) renal involvement. Classification of c-TA required typical angiographic abnormalities of the aorta or its main branches and pulmonary arteries (mandatory criterion) plus one of five criteria: (1) pulse deficit or claudication; (2) blood pressure discrepancy in any limb; (3) bruits; (4) hypertension; (5) elevated acute phase reactant. Conclusion European League Against Rheumatism/Paediatric Rheumatology International Trials Organisation/Paediatric Rheumatology European Society propose validated classification criteria for HSP, c-PAN, c-WG and c-TA with high sensitivity/specificity.

Most epidemiological studies with Wegener`s granulomatosis (WG) patients are based on populations from the Northern hemisphere, whereas very few studies have been conducted in Southern hemisphere populations, particularly from South America. The authors performed a large retrospective, demographic study including clinical and laboratory profiles of 134 consecutive WG patients seen at one Brazilian center from 1999 to 2009. Mean age at initial WG diagnosis was 43.4 +/- 15.5 years, and mean disease duration was 8.6 +/- 6.6 years. Sixty-four (47.8%) patients were male and a total of 113 (84.3%) subjects were white. Ear/nose/throat involvement occurred in 85.8%. The classic lung and renal involvement were observed in 77.6% and 75.4%, respectively, followed by ocular (35.8%), musculoskeletal (33.4%), cutaneous (29.1%), neurological (20.1%), cardiac (11.2%), and genitourinary involvement in 2.2% of cases. Cytoplasmic pattern-antineutrophil cytoplasmic antibody was detected in 83 (61.9%) cases. Ten (7.5%) individuals presented limited forms of WG. Classic therapy with corticosteroids and cyclophosphamide was used in 97 cases (72.4%). There were no cases of tuberculosis or Pneumocystis jiroveci pneumonia, but cutaneous herpes zoster occurred in eight (6.0%) individuals. There were 29 deaths (21.6%). Eighteen patients died of septic shock (mainly bacterial pneumonia), whereas four died of alveolar hemorrhage, four of myocardial infarction, and three of other causes. In summary, our data from a very large retrospective and descriptive study mirrored the main clinical features of WG described in other countries, demonstrating that they may serve as a reference for South American populations.

Descreve-se o caso de um paciente com Granulomatose de Wegener, em tratamento com esteróides e ciclofosfamida, que, apesar do tratamento, evoluiu com dispnéia progressiva e rouquidão. A investigação mostrou tratar-se de uma estenose subglótica, sendo a dispnéia prontamente aliviada com a traqueostomia. São discutidos diagnósticos diferenciais e modalidades de tratamentos de estenose subglótica em portadores de Wegener.

A Granulomatose de Wegener é uma doença sistémica de etiologia desconhecida, caracterizada pela tríade clínica: envolvimento da mucosa nasal e dos seios perinasais, infiltração e cavitação pulmonar e doença renal com hematúria. A Granulomatose de Wegener afecta normalmente adultos jovens e de meia idade e embora seja incomum nas crianças, pode surgir em qualquer estrato etário. Apresentamos o caso clínico de uma adolescente de 14 anos, com sintomas de epistaxis, cuja investigação posterior mostrou insuficiência renal e múltiplos nódulos pulmonares. O teste positivo para o anticorpo antineutrofílico citoplasmático suportou o diagnóstico de Granulomatose de Wegener, necessitando de terapêutica com hemodiálise e imunossupressão.

A granulomatose de Wegener, doença conhecida há aproximadamente 65 anos, continua sendo um dilema para a classe médica, talvez pelo seu polimorfismo clínico, talvez pela carência de métodos diagnósticos. Seu diagnóstico laboratorial repousa no binômio: dosagem do anticorpo anti-neutrófilo em sua fração citoplasmática (ANCA-c) e na obtenção de material para análise anatomopatológica. Descrevemos aqui, o caso de um paciente, em cuja evolução clínica pôde ser observada todo aspecto proteiforme desta doença, chamando atenção para o envolvimento cardíaco. Este último considerado por muitos como pouco usual, manifestou-se clinicamente sob a forma de miocardite, pericardite e de uma massa intracardíaca.

BACKGROUND: Optic perineuritis (OPN) is an inflammatory condition involving the optic nerve sheath because of a variety of causes. We describe three patients in whom OPN was secondary to Wegener's granulomatosis (WG) and compare the clinical findings in these cases with those of idiopathic OPN. METHODS: This is a retrospective small case series derived from patients with OPN seen in an outpatient neuro-ophthalmology clinic. Medical records and imaging studies of these patients were reviewed. RESULTS: These patients shared clinical similarities with idiopathic OPN including age, sex, symptoms, radiographic findings and steroid responsiveness. However, recurrence of symptoms on lowering the prednisone dose below 40 mg distinguished these patients from those with idiopathic OPN. CONCLUSIONS: Steroid dependency in idiopathic OPN should raise suspicion of WG. Patients with OPN should be specifically questioned regarding pre-existing upper respiratory tract disorders and rheumatic symptoms and laboratory testing should include acute phase reactants, anti-neutrophil cytoplasmic antibodies and tests of renal function.

La granulomatosi de Wegener i la síndrome de Churg-Strauss són vasculitis granulomatoses de petit i mitjà vas. Es diagnostiquen mitjançant clínica i biòpsia compatible, i s'associen amb anticossos anticitoplasma de neutròfils. S'ha realitzat un estudi retrospectiu (1984 - 2010) a l'Hospital Universitari Germans Trias i Pujol. Es presenten 15 pacients amb granulomatosi de Wegener. Les característiques clíniques de la present sèrie no difereixen de les descrites prèviament. Es va comparar la supervivència i el dany crònic acumulat en els pacients amb aquestes dues vasculitis. Tant la mortalitat com el dany crònic acumulat resultà superior en el grup de malalts amb granulomatosi de Wegener.

The purpose of this case-based review is to highlight cranial nerve involvement in granulomatosis with polyangiitis (Wegener's). In this disease, cranial nerve involvement may be less frequent than other neurological manifestations, but often goes unrecognized by physicians as a sign of the disease, and its prevalence and importance is likely underestimated. Awareness of this aspect of the disease is necessary to make the proper diagnosis rapidly, as it can be a major feature of a patient's presentation. We also briefly discuss the known pathogenic mechanisms, which could be important when selecting the best therapeutic option.

Objectives To report methodology and overall clinical, laboratory and radiographic characteristics for Henoch-Schonlein purpura (HSP), childhood polyarteritis nodosa (c-PAN), c-Wegener granulomatosis (c-WG) and c-Takayasu arteritis (c-TA) classification criteria.Methods The preliminary Vienna 2005 consensus conference, which proposed preliminary criteria for paediatric vasculitides, was followed by a EULAR/PRINTO/PRES-supported validation project divided into three main steps. Step 1: retrospective/prospective web-data collection for HSP, c-PAN, c-WG and c-TA, with age at diagnosis <= 18 years. Step 2: blinded classification by consensus panel of a subgroup of 280 cases (128 difficult cases, 152 randomly selected) enabling expert diagnostic verification. Step 3: Ankara 2008 Consensus Conference and statistical evaluation (sensitivity, specificity, area under the curve, kappa-agreement) using as 'gold standard' the final consensus classification or original treating physician diagnosis.Results A total of 1183/1398 (85%) samples collected were available for analysis: 827 HSP, 150 c-PAN, 60 c-WG, 87 c-TA and 59 c-other. Prevalence, signs/symptoms, laboratory, biopsy and imaging reports were consistent with the clinical picture of the four c-vasculitides. A representative subgroup of 280 patients was blinded to the treating physician diagnosis and classified by a consensus panel, with kappa-agreement of 0.96 for HSP (95% CI 0.84 to 1), 0.88 for c-WG (95% CI 0.76 to 0.99), 0.84 for c-TA (95% CI 0.73 to 0.96) and 0.73 for c-PAN (95% CI 0.62 to 0.84), with an overall. of 0.79 (95% CI 0.73 to 0.84).Conclusion EULAR/PRINTO/PRES propose validated classification criteria for HSP, c-PAN, c-WG and c-TA, with substantial/almost perfect agreement with the final consensus classification or original treating physician diagnosis.
