ReviewThe eicosapentaenoic acid:arachidonic acid ratio and its clinical utility in cardiovascular disease.
Eicosapentaenoic acid (EPA) is a key anti-inflammatory/anti-aggregatory long-chain polyunsaturated omega-3 fatty acid. Conversely, the omega-6 fatty acid, arachidonic acid (AA) is a precursor to a number of pro-inflammatory/pro-aggregatory mediators. EPA acts competitively with AA for the key cyclooxygenase and lipoxygenase enzymes to form less inflammatory products. ⋯ Increasing the EPA:AA ratio through treatment with purified EPA has been shown in clinical studies to be effective in primary and secondary prevention of coronary artery disease and reduces the risk of cardiovascular events following percutaneous coronary intervention. The EPA:AA ratio is a valuable predictor of cardiovascular risk. Results from ongoing clinical trials will help to define thresholds for EPA treatment associated with better clinical outcomes.

Do practical laboratory indices predict the outcomes of children with Henoch-Schönlein purpura?
Objectives: Henoch Schönlein Purpura (HSP) is the most common systemic vasculitis of childhood and often has a self-limiting course. We aimed to study whether practical laboratory parameters at the diagnosis predict disease course including recurrence and nephritis in addition to severe gastrointestinal involvement in children with HSP. Methods: This retrospective cohort study included 214 HSP patients, 43.5% (n = 93) female and 56.5% (n =121) male, who were diagnosed in our department. ⋯ Neutrophil count and NLR were found higher in HSP patients with severe gastrointestinal involvement and biopsy-proven nephritis. Additionally, only platelet count was lower and MPV was higher in patients with recurrent HSP. Conclusion: Elevated neutrophil count and NLR may be relevant markers for severe GI involvement and nephritis, whereas platelet count and MPV were the only laboratory parameters associated with disease recurrence.
