Cardiac troponin I in fulminant adenovirus myocarditis treated with a 24-hour infusion of high-dose intravenous immunoglobulin

We report a successful outcome on an acute adenovirus myocarditis treated w ith a 24-hour high-dose intravenous immunoglobulin (24-HDIVIG) in a 4.5-yea r-old girl. A postviral etiology of acute myocarditis was assessed on the b asis of the polymerase chain reaction technique. Among other early markers of cardiac injury, cardiac isoform of troponin-I (cTnI) was significantly c orrelated to the left ventricular ejection fraction (r = -0.86, p < 0.0001) , Follow-up of cTnI, which might also be correlated to the short-term outco me, allows fast, easy, and noninvasive estimation of response to the aggres sive treatment with 24-HDIVIG in acute adenovirus myocarditis in children.
