Detection of viral DNA/RNA in children with histological evidence of myocarditis. (A) PCR results from the heart tissue of 306 patients with histologically proven acute myocarditis. (B) PCR results from the heart tissue of 1060 patients with chronic myocarditis. (C) Comparison of viral copy numbers in the heart, buffy coat (BC), and plasma of all children with acute and chronic myocarditis. (D) Comparison of viral copy numbers in heart samples from two age groups (0–2 years and 3–16 years) with acute and chronic myocarditis. B19V viral load is presented as the number of copies per µg of DNA (heart or BC) and per ml of plasma. Data are presented as mean ± SEM; ns, not significant; * p < 0.05, ** p < 0.01, and **** p < 0.0001.
