Filter by:This study will explore safety and efficacy of allogeneic mesenchymal stem cells transplantation (MSCT) to treat patients with diagnosis of primary Sjögren's Syndrome (pSS) who have been resistant to multiple standard treatments. The underlying hypothesis is that the pSS condition is caused by an abnormal immune homeostasis that can be restored by MSCT.
Traditional methodological clinical and instrumental diagnostics of the lacrimal gland for the study of glandular architecture and functions are limited and include analysis of tear constituents, evaluation of apparent diffusion coefficients in magnetic resonance imaging and histopathological evaluation of lacrimal gland biopsy specimens. Confocal microscopy is a new emerging technology which is useful as a supplementary diagnostic tool for in vivo assessment of anterior-segment disorders.The use of in vivo confocal microscopy in a comparative study of the microscopic morphology of the salivary/lacrimal glands have not been reported up to date. In this study, we employ laser scanning confocal microscopy to evaluate the morphological changes of the salivary/lacrimal glands in patients with primary Sjögren's syndrome and compare the results with those of healthy control subjects.
Chronic inflammation that comprises the exocrine glands' function leads to xerophthalmia and xerostomia in Sjögren's syndrome. The oral consequences range widely and they are related to decreased salivary output. Hydroxychloroquine may inhibit cholinesterase activity in salivary glands via interference with antigen processing mechanism, and thus, the investigators' hypothesis was that salivary gland function may be improved if treated with hydroxychloroquine. The effects of hydroxychloroquine on the salivary flow rate, subjective and objective parameters of the patients were also assessed.
This clinical study is to determine whether daily administration of a formulation of 552-02 improves the dry mouth condition in subjects with primary Sjögren's syndrome.
This project will examine the similarities and differences of the ocular surface and tear film in patients with Sjogren's syndrome related to dry eye, severe dry eye and those who do not have dry eye. This knowledge will help clinicians understand the processes that create these dry eye conditions and will strengthen the treatment and management strategies that will be used. The subjects will participate in a series of dry eye tests that they have already experienced in clinic, along with the gathering of tear samples and surface cells. These tissues will then be analyzed at a distant site.
The investigators questioned whether patients with dry mouth complaints display any reduction in residual saliva coating the gingiva and other selected mucosal surfaces. We further intended to test the hypothesis that Gingival Crevicular Fluid volume in patients with dry mouth could be different from that of control subjects. Correlations between gingival/mucosal wetness; and unstimulated whole salivary flow rate or minor salivary gland secretion rates and the correlations between clinical periodontal status and salivary measures were also attempted.
CLINICAL PHASE II INDICATION Sjogren's syndrome RATIONALE Sjögren's syndrome (SS) is an autoimmune disorder affecting 0.2% to 3% of the general population. Pharmacological treatment can improve the sicca symptoms, often transiently, but they are unable to modify the course of the disease.Open label studies suggested that low-dose rituximab produced acute and complete CD20 depletion in blood and tissue; was well tolerated without corticosteroid use; and significantly improved glandular and extra-glandular manifestations of pSS. Larger controlled studies are now warranted. Our hypothesis is that two infusions of 1000 mg of Rituximab may be better than placebo to treat patients suffering from pSS. To test this hypothesis, we propose to compare patients with recent and/or severe pSS treated with either Rituximab or placebo. OBJECTIVES Primary objective : Evaluation of the efficacy defined as a 30% improvement between Day 1 and Week 24 in the values on 2 of the 4 VAS measuring global scores of the disease (activity of the disease including extra glandular manifestations), joint pain, fatigue, and the most disturbing dryness.Secondary objectives : Variations from baseline to week 24 of: The 0-100-mm VAS scores for dry mouth, dry eyes, dry trachea, dry vagina, and dry skin; fatigue; pain; Tender and swollen joint counts; Tender points; Other systemic manifestation; Unstimulated salivary flow rate; Schirmer and van Bijsterveld scores (2-3); C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR); rheumatoid factor (RF); ANA; serum IgG, IgA, and IgM; complement; cryoglobulinemia; and counts of B and T cells; Evaluation of the safety of Rituximab during the study Evaluation of the improvement evaluated on VAS by the physician Evaluation of the disease activity scores as suggested by Bowman and Vitali Evaluation of Chisholm score, B cells characteristics and DNA microarray on labial accessory salivary gland (SG) biopsy samples, and salivary gland echography at inclusion and at week 24. TRIAL DESIGN Multicenter, randomized, double-blind, placebo-controlled trial NUMBER OF SUBJECTS : 120
Fatigue is a prevalent phenomenon in Primary Sjøgrens syndrome (PSS). Observations indicate that the cytokine IL-1 is of importance for this phenomenon. In this study the investigators block IL-1 by giving Anakinra (an IL-1 receptor antagonist) to patients with PSS.
The purpose of this study is to evaluate the effectiveness of NGX267 in the improvement of decreased salivary flow associated with primary or secondary Sjögren's syndrome. For each patient, the study includes four periods of treatment separated by a washout period that may range from 4 - 8 days according to patient and site discretion. Each treatment period includes two overnight stays in the clinic. One dose of study drug is taken during each treatment period
Primary Sjögren's syndrome (SJp) affects 0.1% of the population. This systemic autoimmune disease systemic is characterized by disabling dryness, fatigue and pain, and systemic complications in 30% of patients. No treatment has proven effective in this disease. In open studies, some efficacy was observed with hydroxychloroquine but no RCT versus placebo has ever been done. Thus, the primary purpose of this study is to evaluate the efficacy and safety of hydroxychloroquine (400mg/ day) on dryness, pain, and fatigue, assessed by the patient using visual analogical scales.
