Systemic Diseases

The Systemic Diseases group performs translational research based on at least 300 patients with systemic lupus erytomatosus (SLE), antiphospholipid syndrome (APS), systemic sclerosis, vasculitis, dermatomyitis, Sjörgen syndrome or autoinflammatory syndromes in order to better understand their pathogenesis (both at the immunological and genetic regulation level), study their clinical and biological expression (through the detection of new markers that help characterize each of the autoimmune diseases), study morbimortality (through epidemiological studies) and analyse patients' response to medications. With these goals in mind, we seek to improve the diagnosis, clinical monitoring, and prognosis of our patients.

Proinflammatory cytokines TNF and IL-6 in cellular senescence. A HUVEC aging model.

Cells that are chronically exposed to inflammatory signals are more prone to aging than those which are not exposed to such signals. Human vascular endothelial cell (HUVEC) primary cultures activated with TNF-alpha probably increase the expression of ICAM and VCAM, synthesize ROS, and express senescence markers. It is not known what the principal intracellular pathway is (although it is thought that STAT may play a role) and it is unknown if one or more proinflammatory cytokines are needed to activate NF-KB. We are trying to find out the role that IFN-alpha and/or IL-6 and IL-1B may have on the aging inflammatory phenomena and we aim at detecting the intracellular signal pathways (STAT). We are also working on the characterization of the genes involved in these abnormal biologic responses.

Protein expression of small collagenase 3 and leucine-rich proteoglycans in cutaneous tissue of patients with diffuse scleroderma.

This study, carried out along with researchers from the Hospital del Mar and from the "Institut Municipal d'Investigació Mèdica", aims at correlating the expression of SLRPs and MMP-13 with the severity of cutaneous involvement, hand dysfunctional capacity, capillaroscopy patterns, and cutaneous ultrasonography of patients affected with diffuse scleroderma in different evolutive stages of the disease.

RECORD study (RECOmbinant allergens in diagnosis resolution).

This study aims at detecting the prevalence of specific IgE in polisensitized patients towards pollen in Barcelona by means of the "component resolved diagnosis" technique from ISAC® (IgE specific microarray).

Risk factors for ischemic events in biopsy-proven Giant Cell Arteritis (GCA).

The study aims to investigate the risk factors for ischemic complications in patients with GCA, and the role that some endothelial growth factors may play in its development. This study is coordinated by Dr. Gonzalez Gay from University Hospital of Valdecilla, Santander.
