SAT0513 Brainstem Auditory Evoked Potentials and Visual Potentials in Kawasaki Disease: Expression of CNS Vasculitis?
2015
Background 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. Objectives Brainstem Auditory Evoked Potentials (BAEPs) , and Visual Evoked Potentials (VEPs) were examined in 43 children (age: 0,8-7,5 years) affected by KD. No risk factors for hearing loss and/or neurological impairment of CNS were identified in all the patients. BAEPs showed altered waves II to V, in 18 patients (42%). Among these, in 4 patients (20%) VEPs showed …
THU0260 IL-25 Axis Is Activated and Associated with An ILC2 and M2 Inflammatory State in Patients with Primary Sjogren's Syndrome
2016
Background Type 2 innate lymphoid cells (ILC2) and M2 polarized macrophages are activated and produce cytokines in response to IL-25/IL-17RB, although the relevance of this axis to immune responses in primary Sjoren9s syndrome (pSS) is unknown. Objectives We sought to investigate the role of the IL-25/IL-17RB axis and ILC2 and M2 macrophages in patients with pSS. Methods Expression analysis of IL-17B, IL-25, IL-33 and IL-17RB was performed by TaqMan real-time PCR and immunohistochemistry on salivary glands from 50 patients and 20 controls. Analysis of IL-17RB expression and the frequencies of natural type 2 innate lymphoid cells (nILC2), inflammatory ILC2 (iILC2), and M2-polarized macrophag…
OP0081 Tissue Deficiency of The Atypical Chemokine Receptor D6 Is Associated with The Selective Increase of Gut-Derived Pro-Inflammatory CXCR1HIGHLY6…
2016
Background Gut derived innate lymphoid cells of type 3 (ILC)3 are increased in number in the circulation and inflamed tissues of AS patients. Factors influencing the maintainace of ILC3 in an activated status are not clear. The atypical chemokine receptor D6 is a decoy and scavenger receptor for most inflammatory CC chemokines and acts preventing exacerbated inflammatory reactions. Mice lacking D6 expression in the non-hematopoietic compartment display a significant increase of pro-inflammatory monocytes in the peripheral blood and in secondary lymphoid tissues. The role of D6 in human inflammatory disorders has not been inverstigated. Objectives To evaluate whether modulation of D6 express…
AB0069 Conditioned media from adipose-derived mesenchymal stem cells decreases senescence and enhances collagen ii expression in osteoarthritic chond…
2013
Background Adipose-derived mesenchymal stem cells (ASC) might act as a cellular source of soluble factors exerting anti-inflammatory or trophic effects on cells. Osteoarthritis (OA) is characterized by the progressive loss of structure and functionality of articular cartilage. Objectives In the present study we explored the effect of conditioned medium from adipose-derived mesenchymal stem cells (ASC-CM) on the metabolism of OA chondrocytes in primary culture. Methods ADC were isolated from adipose tissue of patients subjected to abdominal lipectomy surgery, by collagenase treatment. Cells were incubated in DMEM/F12 + 15% human serum. Cell phenotype was analysed by flow cytometry with speci…
Re: ?Splenic marginal zone B-cell lymphoma associated with primary Sj�gren?s syndrome?
2003
We describe a 67-year-old woman with primary Sjögren's syndrome who developed a splenic marginal zone B-cell lymphoma, and complained of a dry mouth and Raynaud's phenomenon. She had splenomegaly, swollen lymph nodes and monoclonal IgM-kappa cryoglobulin. After splenectomy, Raynaud's phenomenon had improved with the decrease of cryoglobulin. This is the first case of primary Sjögren's syndrome with splenic marginal zone B-cell lymphoma to be reported.
PO-0096 Clinical Effectiveness Of Idursulfase In Boys Aged 0–5 Years With Hunter Syndrome: 3-year Data From The Hunter Outcome Survey
2014
Background and aims Symptoms of Hunter syndrome typically become apparent at 2–4 years of age. Previous analyses have demonstrated improvements in certain clinical measures in young patients receiving idursulfase (Shire); however, data on long-term idursulfase use in these patients remain limited. This analysis used data available in the Hunter Outcome Survey (HOS), a global, observational registry sponsored by Shire, to investigate long-term effectiveness of idursulfase in boys with Hunter syndrome aged 0–5 years. Methods As of January 2014, 260/564 males followed prospectively in HOS had received ≥1 idursulfase infusion (excluding those who had received a bone marrow transplant or were en…
PRINTO/PRES international website for families of children with rheumatic diseases: www.pediatric-rheumatology.printo.it
2005
To prepare a website for families and health professionals containing up to date information about paediatric rheumatic diseases (PRD).Firstly, paediatric rheumatology centres and family self help associations were surveyed to characterise current clinical practice of physicians providing care for children with PRD, research activities, and training facilities of each centre. Secondly, international consensus was reached on the content of the website. Finally, the website was developed and the texts translated.The web page contains three main sections: (a) description for families of the characteristics of 15 PRD; (b) list of paediatric rheumatology centres; (c) contact information for fami…
Severe tuberculous meningoencephalitis in a 30-year old woman with active systemic lupus erythematosus.
1997
Tuberculosis is a significant cause of morbidity and mortality in immunocompromising diseases such as systemic lupus erythematosus (SLE). It often is difficult to distinguish between central nervous system (CNS) involvement and infectious complications in SLE. We report the case of a 30-year-old woman with active SLE and severe tuberculous meningoencephalitis. The diagnosis of tuberculous meningoencephalitis was confirmed by cerebrospinal fluid culture examination, which revealed mycobacterium tuberculosis and typical findings for tuberculous meningoencephalitis on magnetic resonance imaging. Despite treatment with isoniazid, rifampicin, ethambutol, streptomycin, and prednisone, the patient…
Trouble always comes in threes: three mutations for three auto inflammatory genes in a child and in his father
2014
The coexistence of mutations in more than one gene, linked to Autoinflammatory Diesases, can confuse and make difficult the diagnosis and management of these patients, especially in childhood, when the clinical history is still brief.
Increased percentages of calprotectin and TNF-Α double-positive monocytes in the acute phase of Kawasaki disease
2011
Background The acute phase of KD is characterized by a deficiency of suppressor T cells, marked activation of the immune system and increased secretion of cytokines by immune effector cells. Moreover, it has been shown that myeloid-related protein (MRP-8 and MRP-14) and S100proteins, the major calcium-binding proteins secreted by activated neutrophils and monocytes, contribute to cause inflammation in acute lesions of KD, and indeed one of the more common hematological alteration in KD is the increase of peripheral blood monocytes. Calprotectin, one of the major calcium-binding proteins, can lead to direct and indirect effects that result not only in inflammation but also in modification of…
