retortaeformis and the persistence GDC-0449 of G. strigosum. A very special thanks to Fabienne Audebert for having enthusiastically inspired and guided IMC to the understanding of T. retortaeformis and G. strigosum parasitology. Special thanks to James McGoldrick and Brian Boag for their patience in embarking on long-term discussions on the biology of helminths and parasitological techniques with IMC and LM. Also but not last IMC is grateful to Peter J. Hudson for discussing the theory of this study while commuting to work. The authors thank A. Pathak for critical comments on the early manuscript. This study and LM were funded by a HFSP and a Royal Society grant. Figure S1. Mean absorbance (OD index ± standard

“Severe pneumonia and leukocytosis are characteristic, frequently observed, clinical findings in pediatric patients with pandemic A/H1N1/2009 influenza virus infection. The aim of this study was to elucidate the role of cytokines and chemokines in complicating pneumonia and leukocytosis in patients with pandemic A/H1N1/2009 influenza virus infection. Forty-seven patients with pandemic A/H1N1/2009 influenza virus infection were enrolled in this study. Expression of interleukin (IL)-10 (P = 0.027) and IL-5 (P = 0.014) was significantly greater in patients with pneumonia than in those without

Sclareol pneumonia. Additionally, serum concentrations of interferon-γ (P = 0.009), tumor necrosis factor-α (P = 0.01), IL-4 (P = 0.024), and IL-2 (P = 0.012) were significantly lower in pneumonia patients with neutrophilic leukocytosis than in those without neutrophilic leukocytosis. Of the five serum chemokine concentrations assessed, only IL-8 was significantly lower in pneumonia patients with neutrophilic leukocytosis than in those without leukocytosis (P = 0.001). These cytokines and chemokines may play important roles in the pathogenesis of childhood pneumonia associated with A/H1N1/2009 influenza virus infection. A/H1N1/2009 influenza virus infection was first reported from Mexico in early March 2009 (1). Soon after discovery of this virus, pandemic infection with it occurred worldwide, including Japan.
