Autoimmune ear disease: clinical and diagnostic relevance in Cogan’s sydrome
2017
The autoimmune inner ear disease is a clinical syndrome with uncertain pathogenesis that is often associated to rapidly progressive hearing loss that, especially at the early stages of disease, may be at monoaural localization, although more often it is at binaural localization. It usually occurs as a sudden deafness, or a rapidly progressive sensorineural hearing loss. In this study a particular form of autoimmune inner ear disease is described, Cogan’s syndrome. Cogan’s syndrome is a chronic inflammatory disorder that most commonly affects young adults. Clinical hallmarks are interstitial keratitis, vestibular and auditory dysfunction. Associations between Cogan’s syndrome and systemic va…
Is TNF-α really involved in giant cell arteritis pathogenesis?
2013
Giant cell arteritis (GCA) is the most frequent vasculitis in people >50 years, and glucocorticoids (GC) remain the cornerstone of the treatment. However, this long-term treatment is responsible for numerous GC-related complications.1 Thus, reliable GC-sparing drugs need to be explored. Seror et al 2 have recently reported the inefficacy of adalimumab, a humanised anti-TNF-α therapy, as a GC-sparing drug in the treatment of GCA. These clinical results contrast with previous studies reporting a production of TNF-α by giant cells and macrophages in GCA lesions.3 However, recent advance in the knowledge of GCA pathogenesis have shown that macrophages and giant cells are not involved in the fir…
Atrial natriuretic factor, but not oxytocin, is present in atherosclerotic plaques of human common carotid arteries
2010
We performed a study on 25 common carotid arteries (CCA) affected by atherosclerotic plaques, comparing them to 25 normal CCA. We researched the presence and localisation of atrial natriuretic factor (ANF) and oxytocin (OX) by immunohistochemistry. We found ANF abundantly expressed in plaques, mainly localising in intima and subintima layers; by contrast normal vessels were scarcely positive or negative; finally, OX resulted negative or weakly positive in both atherosclerotic and normal vessels. Our results show for the first time ANF presence in atherosclerotic plaques of CCA and are in agreement with other studies, mainly performed in vitro, that hypothesise the involvement of this molecu…
Associated arterial and venous cerebral manifestations in Behçet's disease
2018
Behcet's disease is a rare multisystemic vasculitis with an etiology that is still unknown. Neurological manifestations may be seen in approximately 5-15% of patients, and both parenchymal and extraparenchymal neurological involvement has been described. When cerebral venous thrombosis (CVT) is the main extraparenchymal manifestation of Behcet's disease, the condition is then dubbed "angio-Behcet's syndrome". However, arterial involvement is extremely rare, with only one reported case of vasculo-neuro-Behcet's disease, characterized by both venous and intracranial arterial involvement - until now. This report is of two patients diagnosed with Behcet's disease characterized by the concomitan…
EULAR/PRINTO/PRES criteria for Henoch-Schonlein purpura, childhood polyarteritis nodosa, childhood Wegener granulomatosis and childhood Takayasu arte…
2010
EULAR/PRINTO/PRES 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 compar…
18F-FDG PET/TC en infección e inflamación cardiovascular
2021
espanolEn cardiologia nuclear, el diagnostico de infeccion e inflamacion cardiovascular mediante PET/TC con [18F]FDG es de interes creciente, ya que esta tecnica ha mejorado la certeza diagnostica en pacientes con endocarditis infecciosa en protesis valvulares respecto a la ecocardiografia, en pacientes con dispositivos intracardiacos, cuya frecuencia de implantacion va en aumento debido al progresivo envejecimiento de la poblacion, asi como en aquellos con sospecha de vasculitis de grandes vasos. Son situaciones clinicas graves, en las que es necesario establecer lo antes posible el diagnostico correcto y el tratamiento adecuado, pues pueden producir complicaciones severas, alta mortalidad…
HCV-associated cryoglobulinaemia presenting with vasculitis, hepatitis, and glomerulonephritis—a therapeutic dilemma
1996
treated by diet. One year prior to presentation the patient suffered a transitory ischaemic brain attack concomitant with the onset of arterial hypertension, which was subsequently treated with calcium antagonists and beta blockers. Purpura-like skin lesions were noted which were reported to have occurred intermittently over a period of 5 years on both legs and occasionally on the arms. Proteinuria and haematuria were noted during periods with skin lesions.
Microbiome Changes in Connective Tissue Diseases and Vasculitis: Focus on Metabolism and Inflammation
2022
The microbial community acts as an active player in maintaining homeostasis and immune functions through a continuous and changeable cross-talk with the host immune system. Emerging evidence suggests that altered microbial composition, known as dysbiosis, might perturb the delicate balance between the microbiota and the immune system, triggering inflammation and potentially contributing to the pathogenesis and development of chronic inflammatory diseases. This review will summarize the current evidence about the microbiome-immunity cross-talk, especially focusing on the microbiota alterations described in patients with rheumatic diseases and on the recent findings concerning the interaction…
BRAINSTEM AUDITORY EVOKED POTENTIALS AND VISUAL POTENTIALS IN KAWASAKI DISEASE: EXPRESSION OF CNS VASCULITIS?
2015
Kawasaki disease (KD) is an acute, self-limited vasculitis of infants and children that is nowadays the most common cause of acquired heart disease in children. Transient sensorineural hearing loss (20 to 35 dB) is a possible complication of acute phase KD and may be related to salicylate toxicity in some patients.
