Effect of intravenous immunoglobulin for neonates with severe enteroviral infections with emphasis on the timing of administration
Date of Original Version
Background: The benefits of intravenous immunoglobulin (IVIG) therapy for severe neonatal enterovirus infections are still controversial. Object: To evaluate whether timing of IVIG administration might affect clinical outcomes of neonates with severe enteroviral infections. Study designs: We retrospectively analyzed 67 neonates with culture-confirmed severe enteroviral infection, defined as hepatitis with coagulopathy and thrombocytopenia. Clinical features, outcomes and the usage of IVIG therapy were collected and analyzed. IVIG administered within 3 days of illness onset was classified as early IVIG therapy. Results: Of the 67 cases, 38 (57%) were male, 27 (40%) were premature, 57 (85%) had disease onset within 7 days of life and all but 2 cases were caused by coxsackievirus B group. Ten infants (15%) had clinically evident myocarditis. 41 infants (61%) received IVIG therapy and 29 were early IVIG therapy. Fifteen infants (22%) eventually died, without IVIG therapy for 7 infants. The deceased had a significantly higher peak serum aspartate aminotransferase (AST) level than the survivors (3539 vs. 866. IU/L, p<. 0.01). The timing of IVIG therapy was highly correlated with the timing of peak AST level in patients with early IVIG therapy. Multiple logistic regression analysis showed that a higher nadir hemoglobin level (adjusted odds ratio 2.8, 95% confidence interval: 1.4-5.4), no concurrent myocarditis (42.6 [3.4-5289]) and early IVIG therapy (14.7 [1.3-163]) were independently associated with a favorable prognosis. Conclusions: In defined severe neonatal enterovirus infections, serum AST level correlated with the disease severity. Early IVIG therapy, if needed, may be beneficial for survival.
