The ambivalent action of the anti-cancer agent 5-Fluorouracil on myeloid derived suppressor cells under control of docosahexaenoic acid : Role of NLR…
2018
A limitation to 5-Fluorouracil (5-FU) anti-cancer efficacy relies on the secretion of IL-1β by myeloid-derived suppressor cells (MDSC) according to a previous pre-clinical report. The release of mature IL-1β originates from 5 FU mediated NLRP3 activation with increased caspase-1 activity in MDSC and sustains tumor growth recovery in 5 FU treated mice. Docosahexaenoic acid (DHA) belongs to omega-3 fatty acid family and harbors both anti cancer and anti inflammatory properties which might could improve 5 FU chemotherapy. Here, we demonstrate that DHA inhibits 5 FU induced IL 1β secretion produced by a MDSC cell line (MSC-2). In tumor-bearing mice treated with 5 FU, we showed that a DHA enrich…
A randomized multicenter study comparing seawater washes and carmellose artificial tears eyedrops in the treatment of dry eye syndrome.
2019
Purpose To investigate the safety and efficacy of sterile isotonic seawater washes vs standard treatment with carmellose artificial tears in dry eye syndrome (DES). Patients and methods This is a randomized multicenter prospective study with 12 weeks of follow-up. A group of patients with DES (N=60) were treated with seawater spray (Quinton®) five times daily, and another similar group (N=60) were treated with carmellose artificial tears eyedrops (Viscofresh® 0.5%) five times a day. The parameters studied and measured were as follows: Ocular Surface Disease Index questionnaire score, Schirmer I test (without anesthesia) score, tear osmolarity (TearLab®), tear breakup time, tear meniscus hei…
EVALUATION OF SERUM LEVELS OF ASC FOR THE DIAGNOSIS AND MONITORING OF CRYOPYRIN ASSOCIATED PERIODIC SYNDROMES (CAPS)
2019
Background: Dominantly gain-of-function mutations in the NLRP3 gene lead to Cryopyrin associated periodic syndromes (CAPS) characterized by constitutive activation of the inflammasome, increased secretion of interleukin (IL)-1beta and IL-18, and systemic inflammation. IL-1beta and active caspase-1 subunits are released in the serum together with the oligomeric particles of the adaptor ASC (apoptosis-associated Speck-like protein with a caspase-recruitment domain) after activation of the inflammosome complex and, as a consequence, patients with CAPS show an increased serum concentration of ASC+ particles. Objectives: Patients suffering from CAPS are characterized by clinical manifestation si…
