S100A8 and asthma: The other survey of 7,663 adults (NHANES 1999–2000) with asthma, allergic rhinitis, and atopic disorder by the same group (Chen and Blaser, 2007) also revealed that antibody to the H. pylori cytotoxin-associated gene product (CagA), a marker of more inflammatory type of H. pylori infection, was inversely correlated with asthma (OR 0.79; 95% CI 0.63–0.99) and allergic rhinitis (OR 0.77; 95% CI 0.62–0.94), especially among those who developed these conditions in childhood (Table 1; Study No. 10).
