Evaluation of smell and taste in patients with Wegener's granulomatosis

Although a reduced olfactory/gustatory function affects patients in all parts of life, this problem has not received much attention in Wegener's granulomatosis (WG). The aim of this study was to assess the smell/taste function of WG patients. Demographic data of 16 WG patients (9 males, 7 females) were obtained. They all subjectively assessed their taste/smell function on visual analogue scale. Olfactory/gustatory functions of the patients were tested with 'Sniffin' Sticks and 'Taste' strips, respectively. The results were then compared with those from sex and age-matched control group (n = 16) and normative data. WG patients subjectively assessed their olfactory (p = 0.03) and gustatory (p = 0.02) function to be lower than control group. All the olfactory scores (odour identification, odour discrimination and threshold) in both genders were significantly below the scores in the control group. WG patients were hyposmic. For taste (total taste score, as well as scores for the qualities sweet, sour, salty and bitter), WG patients did not significantly differ from controls and were normogeusic. However, the gustatory scores showed the tendency of reduction as compared to the control group. In conclusion, WG patients truly suffer from olfactory/taste dysfunction, but this is worse with olfaction. It is, therefore, imperative that physicians should make their patients to be aware of these sensory dysfunctions and educate them on methods to cope with it for better quality of life.

Comprometimento da árvore respiratória na granulomatose de Wegener

INTRODUÇÃO: A granulomatose de Wegener (GW) é uma forma de vasculite sistêmica que envolve primariamente as vias aéreas superiores e inferiores e os rins. As manifestações mais frequentes nas vias aéreas são estenose subglótica e inflamações, estenoses da traqueia e dos brônquios. A visualização endoscópica das vias aéreas é a melhor ferramenta para avaliação, diagnóstico e manejo dessas alterações. OBJETIVOS: Descrever as alterações endoscópicas encontradas na mucosa das vias aéreas de um grupo de pacientes com GW submetido à broncoscopia no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP) e relatar as intervenções terapêuticas broncoscópicas utilizadas em alguns casos. MÉTODOS: Foram estudados 15 pacientes com diagnóstico de GW provenientes do Ambulatório de Vasculites da Disciplina de Pneumologia do HC-FMUSP, encaminhados para a realização de broncoscopia no serviço de Endoscopia Respiratória do HC-FMUSP no período de 2003 a 2007. RESULTADOS: Dos 15 pacientes avaliados, 11 eram mulheres (73,33%) com idade média de 34 ± 11,5 anos. Foram encontradas alterações das vias aéreas em 80% dos pacientes, e o achado endoscópico mais frequente foi estenose subglótica (n = 6). Realizou-se broncoscopia terapêutica em três pacientes com estenose subglótica e em outros três com estenose brônquica, todos apresentando bons resultados. CONCLUSÃO: A broncoscopia permite diagnóstico, acompanhamento e tratamento das lesões de vias aéreas na GW, constituindo-se um recurso terapêutico pouco invasivo em casos selecionados.

Antineutrophil cytoplasmic antibodies in myelodysplasia

Antibodies to neutrophil cytoplasmic antigens (ANCA) are good serological markers for patients with mainly vasculitic conditions. Two main types of ANCAs have been detected, the first termed cytoplasmic antineutrophil cytoplasmic antibody (cANCA) are mainly associated with patients with Wegener's granulomatosis, the other termed perinuclear antineutrophil cytoplasmic antibody (pANCA) are mainly associated with patients with renal vasculitis, rheumatic and collagen disorders. These antibodies are against various constituents of neutrophil granules. In patients with myelodysplasia, defects in normal granulocyte development are seen. We report a series of twelve patients with myelodysplasia of whom at least four showed a low titre and one a high titre of pANCA. Two of these patients also had demonstrable activity against myeloperoxidase (MPO). None of these patients had any evidence of systemic or cutaneous vasculitis or of any autoimmune disorder. There was no pANCA positivity in an age matched control group.

A curious case of hiccoughs - unusual presentation of eosinophilic granulomatosis with polyangiitis

We report a case of eosinophilic GPA (EGPA) presenting with persistent hiccoughs. The diagnosis was based on clinical and histological findings. Induction treatment with corticosteroids led to clinical improvement and rapid resolution of hiccoughs. Hiccoughing has never before been associated with acute EGPA and may reflect involvement of the phrenic and/or vagus nerves.

THE ARTIFICIAL URINARY SPHINCTER - A NEW SOLUTION FOR INCONTINENT PATIENTS

Treatment of urinary incontinence with the artificial urinary sphincter has been available in centres such as London and Liverpool for a number of years. This service is now available in the department of urology of the Belfast City Hospital. Twelve patients have had successful implantation of an artificial urinary sphincter for urinary incontinence, and ten are now fully continent. One patient with Wegener's granulomatosis developed active disease in his urethra which has precluded activation of the device. One patient has had the device removed because of erosion into the urethra.

Primary diffuse large B-cell lymphoma or lymphomatoid granulomatosis grade 3: a still-puzzling diagnosis in autopsy

Primary lung lymphoma is a rare entity accounting for approximately 0.3% of all primary neoplasia of the lung and includes diffuse large B-cell lymphoma (DLBL) and lymphomatoid granulomatosis (LYG). Considering that clinical features may be similar, whereas epidemiology, morphology, and radiological features are different, the authors report a case of a middle-aged man who presented multiple pulmonary nodules in the lower lobes and groundglass opacities scattered bilaterally on computed tomography. Clinically, he presented a consumptive syndrome with respiratory failure and pleurisy, which progressed until death. The autopsy findings were consistent with lymphomatoid granulomatosis (LYG) grade 3/ diffuse large B-cell lymphoma (DLBL). The authors call attention to the difficulty of establishing an accurate diagnosis, mainly when the demonstration of EBV-infected atypical B-cells fails.

Utilizzo del Rituximab nel trattamento della vasculiti ANCA associate.

Introduzione. Recenti studi hanno dimostrato che il Rituximab (RTX) è un’alternativa sicura ed efficace alla ciclofosfamide nell’indurre la remissione in pazienti con severa vasculite ANCA-associata (AAV) di nuova diagnosi o recidiva. Scopo dello studio era valutare l’efficacia e la sicurezza del RTX nei nostri pazienti con AAV. Metodi. Studio retrospettivo delle caratteristiche cliniche, dei risultati e della tolleranza al RTX dei pazienti con AAV trattati presso il nostro centro da Gennaio 2006 a Dicembre 2011. Inizialmente veniva utilizzato lo schema convenzionale delle 4 somministrazioni settimanali da 375 mg/m2. Dal 2011 sulla base dell’esperienza maturata e dei nuovi dati della letteratura si decideva di non adottare uno schema fisso per le recidive, ma di somministrare una o due dosi secondo la severità della recidiva ed il rischio infettivo. Risultati. Venivano trattati 51 pazienti con AAV, 15/51 (29%) di nuova diagnosi e 36/51 (71%) ad una recidiva. La maggior parte dei pazienti con nuova diagnosi presentavano una micropoliangioite con severo interessamento renale, 5/15 (33%) erano in dialisi dall’esordio. 32/36 (89%) pazienti trattati ad una recidiva presentavano una recidiva granulomatosa di Granulomatosi di Wegener (WG). Tutti ottenevano una remissione, più rapidamente per le manifestazioni vasculitiche. 2/5 pazienti in dialisi dall’esordio recuperavano la funzione renale. Si osservavano 11 recidive in 9 pazienti con GW mediamente dopo 23.1 mesi, tutti ottenevano nuovamente la remissione. Ad un follow-up medio di 20.1 mesi si registravano 4 decessi, 3 (3/15, 20%) nel gruppo di pazienti con nuova diagnosi, uno (1/36, 3%) nel gruppo trattato ad una recidiva. Quattro pazienti sospendevano il RTX per infezioni. Conclusioni. Nella nostra casistica il RTX si è dimostrato efficace e sicuro nell’indurre la remissione in pazienti con severa AAV, sia all’esordio che alla recidiva. I pazienti con WG presentano maggior rischio di recidiva e dovrebbero pertanto essere mantenuti in terapia immunosoppressiva dopo RTX.

[Systemic ANCA-associated vasculitis--diagnosis and therapy]

ANCA-associated vasculitis represents a group of small-vessel vasculitides, including Wegener's granulomatosis, microscopic polyangiitis and the Churg-Strauss-syndrome. These diseases affect mainly small arteries, venules and capillaries, showing a lack of immunocomplex formation on immunohistology, the so-called "pauci-immune" vasculitis. Nevertheless, Anti-Neutrophil Cytoplasmatic Autoantibodies (ANCA's) are pathogenic for this type of disease. In spite of important advances in technical diagnostic tools, careful medical history and clinical examinations often give the clues for the correct diagnosis. Recent collaborative therapeutic studies have lead to therapeutic schemas that are much more adapted to the individual disease state. Besides the acute and sometimes life-threatening form of ANCA-vasculitis, chronic disease and relapses become more important in clinical practice. Thus, therapeutic efficacy must be outweighed against long-term toxicity to make the right choice for therapeutic intervention in ANCA-associated vasculitis.
