A positive lymphocyte transformation test to beta-lactams (beta-L) was found in 12 of 29 subjects with adverse drug reaction (ADR) to beta-L, irrespective of either the type of clinical manifestation or the presence of specific serum IgE. Short-term T cell lines specific for penicillin G, amoxicillin, and ampicillin could be generated only from subjects(More)
AIM A growing number of neuropsychological studies reported that chemotherapy may impair brain functions, inducing persistent cognitive changes in a subset of cancer survivors. The aim of this paper was to investigate the neural basis of the chemotherapy induced neurobehavioral changes by means of metabolic imaging and neuropsychological testing. METHODS(More)
The cost effectiveness of treatments that have changed the "natural history" of a chronic progressive disease needs to be evaluated over the long term. Disease-modifying antirheumatic drugs (DMARDs) are the standard treatment of rheumatoid arthritis (RA) and should be started as early as possible. A number of studies have shown that they are effective in(More)
BACKGROUND We analyzed the performance of a novel ENA screening chemiluminescent immunoassay (CIA) and the confirmation QUANTA Flash tests. METHODS Sera (n=1079) from patients referred to a rheumatology clinic were screened by QUANTA Flash ENA7 (INOVA Diagnostics). All positive (n=89) and a matched control group (n=90) were reflexed for autoantibodies to(More)
INTRODUCTION The objective of the present study was to compare QUANTA Flash dsDNA, a chemiluminescent immunoassay (CIA) on the BIO-FLASH, a rapid-response chemiluminescent analyzer, to three other anti-dsDNA antibody assays and to Crithidia luciliae indirect immunofluorescence test (CLIFT). METHODS In the first part of the study, 161 samples, 61 from(More)
ACPA (anti-citrullinated protein antibody) tests are today systematically added to clinical and radiological investigations when diagnosing rheumatoid arthritis (RA), and the inclusion of ACPA positivity in the new 2010 RA criteria underlines their importance. The aim of this study was to determine the sensitivity and specificity of different ACPA assays(More)
We evaluated the efficacy of clodronate for treating active erosive osteoarthritis of the hand and to compare it with hydroxychloroquine. Group A consisted of 24 patients treated for 24 months with clodronate 300 mg i.v. for 7 days, followed by clodronate i.m. 100 mg for 14 days every 3 months. Group B comprised 14 patients treated with hydroxychloroquine(More)
OBJECTIVE The polymorphism 158V/F of Fc fragment of IgG (FCGR) type 3A may influence the response to rituximab (RTX) in rheumatoid arthritis (RA). We investigated the FCG3A polymorphism in a large cohort of RA patients treated with RTX, also by considering the possible loss of response from month +4 to +6 after RTX and the presence of established predictors(More)
INTRODUCTION This multicenter study aimed to evaluate the diagnostic value of 2 cellular tests based on basophil reactivity--the basophil activation test (BAT, Flow-CAST) and the sulfidoleukotriene release assay (CAST-ELISA)--in immediate-type beta-lactam allergy, particularly in patients with a clinical history of allergy and a negative skin test result.(More)
