Inducible lectins with galectin properties and human IL1alpha epitopes opsonize yeast during the inflammatory response of the ascidian Ciona intestin…

2007

Studies on inducible ascidian lectins may shed light on the evolutionary emergence of cytokine functions. Here, we show that the levels of opsonins, with IL1alpha-epitopes, increase in Ciona intestinalis hemolymph as a response to an inflammatory stimulus and, in particular, to intratunic injection of lipopolysaccharide (LPS). The inflammatory agent promptly (within 4 h) enhances Ca(2+)-independent serum hemagglutinating and opsonizing activities, which are both inhibited by D-galactose and D-galactosides (alpha-lactose, N-acetyl-D-lactosamine, thio-digalactoside), suggesting that anti-rabbit erythrocyte lectins with galectin properties are involved as opsonins. Inducible galectin molecules…

TNFα Primes Polymorphonuclear Leukocytes for an Enhanced Respiratory Burst to a Similar Extent As Bacterial Lipopolysaccharide

1990

We examined whether preincubating polymorphonuclear leukocytes (PMN) with TNF alpha would result in an enhanced respiratory burst upon subsequent stimulation by various agents. Bacterial lipopolysaccharide (LPS), a known primer of PMN, was used as control. We found that both LPS (0.01 to 10.0 microgram/ml) and recombinant TNF alpha (0.001 to 1.0 microgram/ml) act as direct stimulants of PMN as measured by chemiluminescence. Sixty minutes of preincubation of PMN with 1 microgram/ml TNF alpha or 10 micrograms/ml LPS resulted in similar priming for the respiratory burst elicited by opsonized zymosan, phorbol myristate acetate, zymosan, zymosan-activated serum, aggregated immunoglobulin, and f-…

Combination therapy of recalcitrant severe psoriasis with psoriatic arthritis, diabetes nephropathy, and liver cirrhosis

2021

Objective Treatment of recalcitrant moderate-to-severe psoriasis can be challenging. Combination therapy of biologics and immunosuppressive agents can be a new strategy for treating therapy-resistant cases with comorbidities, where many systemic medications are contraindicated. Case presentation We report a case of a 62-year-old diabetic man with a 30-year history of severe plaque psoriasis and psoriatic arthritis with cirrhosis and diabetic nephropathy that was treated successfully in combination with apremilast and etanercept after multiple previous unsuccessful treatment attempts. Conclusion There are no data supporting the combination of apremilast and etanercept in the management of re…

Geostatistical 3-dimensional integration of measurements of soil magnetic susceptibility.

2010

In soil magnetometry, two types of measurements are usually performed. The first type is measurements performed on the soil surface, frequently using an MS2D sensor. The second type includes measurements of magnetic susceptibility carried out in the soil profile, usually to a depth of about 30 cm. Up to now, such measurement results were analyzed separately. However, it is possible and advantageous to integrate these two types of measurements. The goal of the study was to integrate measurements of magnetic susceptibility performed on the soil surface and in the soil profile. More specifically, the goal was to obtain 3-dimensional spatial distributions of magnetic susceptibility of the topso…

Interleukin-17 Inhibition in Spondyloarthritis Is Associated With Subclinical Gut Microbiome Perturbations and a Distinctive Interleukin-25-Driven In…

2020

Objective To characterize the ecological effects of biologic therapies on the gut bacterial and fungal microbiome in psoriatic arthritis (PsA)/spondyloarthritis (SpA) patients. Methods Fecal samples from PsA/SpA patients pre- and posttreatment with tumor necrosis factor inhibitors (TNFi; n = 15) or an anti-interleukin-17A monoclonal antibody inhibitor (IL-17i; n = 14) underwent sequencing (16S ribosomal RNA, internal transcribed spacer and shotgun metagenomics) and computational microbiome analysis. Fecal levels of fatty acid metabolites and cytokines/proteins implicated in PsA/SpA pathogenesis or intestinal inflammation were correlated with sequence data. Additionally, ileal biopsies obtai…

Patient-reported impact of spondyloarthritis on work disability and working life: the ATLANTIS survey

2016

Background The aim was to establish how patients experience the impact of spondyloarthritis (SpA) on work disability and working life. Methods The survey was performed in 17/20 regions in Italy (1 January to 31 March 2013). A multiple-choice questionnaire was published on the official website of the sponsor - the National Association of Rheumatic Patients (ANMAR) - and hard-copies were distributed at outpatient clinics for rheumatic patients. Results Respondents (n = 770) were of both sexes (56 % men), educated (62 % at high school or more), of working age (75 % aged ≤60 years), and affected by SpA. The most common types diagnosed were ankylosing spondylitis (AS) (39 %) and psoriatic arthri…

Incidence, Clinical Characteristics, and Management of Psoriasis Induced by Anti-TNF Therapy in Patients with Inflammatory Bowel Disease: A Nationwid…

2016

Background: Psoriasis induced by anti-tumor necrosis factor-alpha (TNF) therapy has been described as a paradoxical side effect. Aim: To determine the incidence, clinical characteristics, and management of psoriasis induced by anti-TNF therapy in a large nationwide cohort of inflammatory bowel disease patients. Methods: Patients with inflammatory bowel disease were identified from the Spanish prospectively maintained Estudio Nacional en Enfermedad Inflamatoria Intestinal sobre Determinantes geneticos y Ambientales registry of Grupo Espanol de Trabajo en Enfermedad de Croh y Colitis Ulcerosa. Patients who developed psoriasis by anti-TNF drugs were the cases, whereas patients treated with ant…

Real-life effectiveness of ustekinumab in inflammatory bowel disease patients with concomitant psoriasis or psoriatic arthritis: An IG-IBD study

2019

Abstract Background Few data exist regarding the effectiveness of ustekinumab in inflammatory bowel disease (IBD) patients treated for concomitant psoriasis or psoriatic arthritis. Aims to describe the outcomes of IBD patients who received subcutaneous ustekinumab through a dermatological or rheumatological prescription. Methods This multicenter, retrospective study included all IBD patients who were started on ustekinumab for concomitant active psoriasis/ psoriatic arthritis, irrespective of IBD activity. The primary endpoint was overall ustekinumab persistence, defined as the maintenance of therapy because of sustained clinical benefit for IBD. Results Seventy patients (64 Crohn’s disease…

Pruritus characteristics in a large Italian cohort of psoriatic patients

2019

Background: Psoriasis (Ps) is a chronic systemic autoimmune disease associated with pruritus in 64–98% of patients. However, few modestly sized studies assess factors associated with psoriatic pruritus. Objective: To investigate factors associated with Ps pruritus intensity. Methods: Psoriasis patients 18 years or older seen in one of 155 centres in Italy between September 2005 and 2009 were identified from the Italian PsoCare registry. Patients without cutaneous psoriasis and those with missed information on pruritus were excluded. Results: We identified 10 802 patients, with a mean age 48.8 ± 14.3 years. Mild itch was present in 33.2% of patients, moderate in 34.4%, severe in 18.7% and ve…
