Objective. Patients with an HLA-B*58:01 allele have increased risk of developing severe cutaneous adverse drug reactions (SCAR) when treated allopurinol. Although one-off pharmacogenetic testing may prevent life-threatening reactions, prior to allopurinol initiation incurs additional costs. The study objective was evaluate the cost-effectiveness screening compared using other available urate-lowering agents (ULA). Methods. A decision-analytical model used compare direct medical costs and...

Behçet's disease (BD) is a recurrent, multisystemic, inflammatory disorder that mainly affects blood vessels. Because recurrent inflammation of vessels in the brain plays crucial role development ischemic stroke, we hypothesized patients with BD might have an elevated risk stroke. This potential association has been suggested few case reports, but not epidemiological studies. Hence, present study aimed to examine relation between and subsequent stroke Taiwan using nationwide,...
