The primary outcome was to assess, once remission was achieved, the time in remission up to the first flare after discontinuing treatment. Mann-Whitney U test, Wilcoxon's signed rank test for paired samples, chi-square tests, and Fisher's exact test were used to compare data. Pearson's and Spearman's correlation tests were used to determine correlation coefficients for different variables. To identify predictors of outcome, Cox regression model and Kaplan-Meier curves were constructed, each one at the mean of entered covariates.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS: &lt;/b&gt;The majority of enrolled patients flared after stopping treatment with biologics (102 of 135, 75.6%) after a median followup time in remission off therapy of 6 months (range 3-109 months). A higher probability of maintaining remission after discontinuing treatment was present in systemic-onset disease compared to the rest of the JIA patients (Mantel-Cox χ = 8.31, P &lt; 0.004). In analysis limited to children with JIA with polyarticular and oligoarticular disease, patients who received biologics &gt;2 years after achieving remission had a higher probability of maintaining such remission off therapy (mean ± SD 18.64 ± 3.3 months versus 11.51 ± 2.7 months [P &lt; 0.009]; Mantel-Cox χ = 9.06, P &lt; 0.002). No other clinical variable was significantly associated with a long-lasting remission.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSION: &lt;/b&gt;Children with oligoarticular and polyarticular JIA who stop treatment before 2 years from remission have a higher chance of relapsing after biologic withdrawal.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/28973842?dopt=Abstract</style></custom1></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Agostinis, Chiara</style></author><author><style face="normal" font="default" size="100%">Durigutto, Paolo</style></author><author><style face="normal" font="default" size="100%">Sblattero, Daniele</style></author><author><style face="normal" font="default" size="100%">Borghi, Maria O</style></author><author><style face="normal" font="default" size="100%">Grossi, Claudia</style></author><author><style face="normal" font="default" size="100%">Guida, Filomena</style></author><author><style face="normal" font="default" size="100%">Bulla, Roberta</style></author><author><style face="normal" font="default" size="100%">Macor, Paolo</style></author><author><style face="normal" font="default" size="100%">Pregnolato, Francesca</style></author><author><style face="normal" font="default" size="100%">Meroni, Pier Luigi</style></author><author><style face="normal" font="default" size="100%">Tedesco, Francesco</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A non-complement-fixing antibody to β2 glycoprotein I as a novel therapy for antiphospholipid syndrome.</style></title><secondary-title><style face="normal" font="default" size="100%">Blood</style></secondary-title><alt-title><style face="normal" font="default" size="100%">Blood</style></alt-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Abortion, Spontaneous</style></keyword><keyword><style  face="normal" font="default" size="100%">Animals</style></keyword><keyword><style  face="normal" font="default" size="100%">Antibodies, Monoclonal</style></keyword><keyword><style  face="normal" font="default" size="100%">Antiphospholipid Syndrome</style></keyword><keyword><style  face="normal" font="default" size="100%">Autoantigens</style></keyword><keyword><style  face="normal" font="default" size="100%">beta 2-Glycoprotein I</style></keyword><keyword><style  face="normal" font="default" size="100%">Complement Activation</style></keyword><keyword><style  face="normal" font="default" size="100%">Complement System Proteins</style></keyword><keyword><style  face="normal" font="default" size="100%">Human Umbilical Vein Endothelial Cells</style></keyword><keyword><style  face="normal" font="default" size="100%">Humans</style></keyword><keyword><style  face="normal" font="default" size="100%">Immunoglobulin G</style></keyword><keyword><style  face="normal" font="default" size="100%">Male</style></keyword><keyword><style  face="normal" font="default" size="100%">Mice</style></keyword><keyword><style  face="normal" font="default" size="100%">Protein Binding</style></keyword><keyword><style  face="normal" font="default" size="100%">Rats</style></keyword><keyword><style  face="normal" font="default" size="100%">Recombinant Proteins</style></keyword><keyword><style  face="normal" font="default" size="100%">Single-Chain Antibodies</style></keyword><keyword><style  face="normal" font="default" size="100%">Thrombosis</style></keyword><keyword><style  face="normal" font="default" size="100%">Trophoblasts</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2014</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2014 May 29</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">123</style></volume><pages><style face="normal" font="default" size="100%">3478-87</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;A single-chain fragment variable (scFv) recognizing β2-glycoprotein 1 (β2GPI) from humans and other species was isolated from a human phage display library and engineered to contain an IgG1 hinge-CH2-CH3 domain. The scFv-Fc directed against β2GPI domain I-induced thrombosis and fetal loss, thus mimicking the effect of antibodies from patients with antiphospholipid syndrome (APS). Complement is involved in the biological effect of anti-β2GPI scFv-Fc, as demonstrated by its ability to promote in vitro and in vivo complement deposition and the failure to induce vascular thrombosis in C6-deficient rats and fetal loss in C5-depleted mice. A critical role for complement was also supported by the inability of the CH2-deleted scFv-Fc to cause vessel occlusion and pregnancy failure. This antibody prevented the pathological effects of anti-β2GPI antibodies from APS patients and displaced β2GPI-bound patient antibodies. The CH2-deleted antibody represents an innovative approach potentially useful to treat APS patients refractory to standard therapy.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">22</style></issue><custom1><style face="normal" font="default" size="100%">http://www.ncbi.nlm.nih.gov/pubmed/24642748?dopt=Abstract</style></custom1></record></records></xml>
