Naïve sea bass juveniles (38.4 + or - 4.5 g) were intramuscularly infected with a sublethal dose of betanodavirus isolate 378/I03, followed after 43 days by a similar boosting. This infection resulted in an overall mortality of 7.6%. At various intervals, sampling of fish tissues was performed to investigate: i) B and T lymphocyte content in organs and(More)
Viral encephalopathy and retinopathy, otherwise known as fish encephalitis or viral nervous necrosis (VNN), is an emerging problem in several farmed marine fish species in various geographic areas all over the world. Since summer 1995, heavy losses affecting mainly juvenile and adult sea bass (Dicentrarchus labrax) have been observed in several on-growing(More)
PURPOSE To measure markers of leukocyte activation in patients with an exclusively ocular inflammatory or bacterial disease. METHODS Neutrophil myeloperoxidase, eosinophil cationic protein, eosinophil neurotoxin, and soluble interleukin-2 receptor were measured in serum and tears of 17 patients with allergic vernal keratoconjunctivitis, seven with atopic(More)
The objectives of this study were to determine: 1) levels of tear eosinophil cationic protein (ECP) in patients with vernal keratoconjunctivitis (VKC); 2) the effect of pharmacologic therapy on ECP release; and 3) the correlation of this mediator with the severity of the disease. Tears were collected from 10 controls and 20 VKC patients before and after(More)
The effects of short-term thymic hormone administration on age-associated immune function were evaluated. Two groups of individuals greater than 65 years of age were treated for 30 days with thymic extracts (TP1) or placebo; before and after this treatment a panel of in vitro and in vivo parameters was determined according to a very rigorous experimental(More)
AIM To validate the use of tear eosinophil cationic protein (ECP) as a marker for eosinophil activation, and its pharmacological modulation, in addition to evaluating the efficacy of lodoxamide and sodium cromoglycate in the treatment of vernal keratoconjunctivitis (VKC). METHODS Tears were collected from 30 patients affected by active mild to moderate(More)
In order to establish the most efficient thresholds for serum allergen-specific IgE measured by the Pharmacia CAP System, a "second-generation" in vitro method, we evaluated results from 89 subjects with suspected inhalant allergies, using receiver-operating characteristic (ROC) curve analysis. Sera samples were analyzed by the Pharmacia CAP System for(More)
To quantify the presence of inflammatory/fibrogenic cytokines and procollagens type I (PICP) and III (PIIIP) in active and non-active tarsal and limbal forms of vernal keratoconjunctivitis (VKC), tear and blood samples were collected from 27 VKC patients (20 active and 7 non-active) and 15 normal subjects. Upper tarsal conjunctival biopses were obtained(More)
Recently introduced "second-generation" techniques for specific IgE measurement have produced some analytical improvement, offering better clinical sensitivity than previous techniques. The aims of our study were to compare the analytical and clinical performances of four second-generation techniques for allergen-specific IgE measurement in serum and to(More)
We studied the analytical and clinical efficiency of a "second generation" technique for the in vitro determination of specific IgE, the so-called CARLA system (Capture Assay Radim Liquid Allergen). Reproducibility studies demonstrated satisfactory intra- and inter-assay analytical imprecision. The linearity test gave good results, and no significant(More)
