Filter by:This study is a preliminary investigation, with a single-group design, not randomized and transparent, focusing on treatment. Its purpose is to identify the highest dose of BH002 injection (CD19-BCMA CAR-T cells) that patients suffering from resistant systemic lupus erythematosus can tolerate.
The goal of this clinical trial is to verify whether CHIP is correlated with the clinical, instrumental, and histological characteristics of GCA, and to characterize the pathogenetic effects of clonal hemopoiesis on vasculitis. The main objective of this study is to verify if clonal hematopoiesis of indeterminate potential (CHIP) affects GCA manifestations, course/response to therapies, and pathogenesis. Patients who are going to be diagnosed with GCA and for which a fast track is available for a rapid diagnostic work-up including pre-treatment temporal artery biopsy. Patients with CHIP will be identified and characterized by using whole exome sequencing from the peripheral blood samples. The presence and characteristics of CHIP will be correlated with baseline clinical, instrumental, and histologic GCA features.
This is a case-control observational study on blood samples. The primary goal of this study is to identify the epigenetic marks that can distinguish patients suffering from Eosinophilic Granulomatosis with Polyangiitis (EGPA) from healthy individuals. The secondary goal is to identify epigenetic or transcriptional marks that can predict if a patient with EGPA will benefit from therapy with Mepolizumab. This study is observational, meaning there will be no alterations of patients' routine clinical care. A blood sample will be drawn for each patient. If the patient will undergo treatment with Mepolizumab (based on routine clinical care), then the blood sample will be drawn before Mepolizumab initiation. The blood samples will be used for genome-wide DNA methylation profiling and for transcriptomic profiling. Healthy individuals as controls for the association study will not be recruited. In fact, the epigenetic and transcriptomic data obtained from EGPA patient blood will be compared against already available genome-wide DNA methylation and transcriptomic profiles of the blood of healthy individuals from previous studies. A total of 300 patients with EGPA will be recruited for the study. The first part of the study, corresponding to the primary goal, will involve all of the 300 patients. The second part of the study, corresponding to the secondary goal, will involve a study population subset consisting of 50 patients.
The purpose of this study is to identify the most promising therapeutic strategy for patients with granulomatosis with polyangiitis and inadequate response to standard of care therapy. It will evaluate the efficacy to induce remission of three different salvage strategies including: a combination of rituximab with addition of a conventional disease-modifying antirheumatic drugs (either methotrexate, azathioprine or mycophenolate mofetil, but preferentially methotrexate); tocilizumab; or abatacept.
This study will address the following hypothesis: Rituximab therapy leads to an acquired immune deficiency, as demonstrated by impaired vaccine responses, in AAV patients. Aims: 1. To investigate whether rituximab leads to immune deficiency in patients with AAV when compared to both disease and healthy controls. 2. To investigate whether the degree of immune deficiency is associated with the degree of B cell depletion. 3. To investigate whether T-independent vaccine responses are more severely affected than T-dependent vaccine responses after rituximab and whether a conjugated vaccine will overcome this postulated deficit in T independent vaccine responses.
The purpose of this study is to observe the clinical manifestation, Lab findings including chest CT scans, pathological findings and outcomes in chinese patients with pulminary vasculitis.
