Mean ratios of serum Hp-specific IgG1 (A), IgG2 (B), IgG3 (C) and IgG4 (D) from Hp-positive children and adults from Tumaco and Pasto/Tuquerres were stratified by seronegative (−) or positive (+) status for Al and Tg and compared by the two-tailed Student’s t-test. IgG titers to Al were associated with enhanced anti-inflammatory Th2-asssociated IgG1 responses to Hp in both Tg seronegative (** p<0.01) and Tg seropositive individuals (* p<0.05). Tg seropositivity was linked to higher pro-inflammatory Th1-IgG2 (*** p<0.0001), as well as IgG3 (*** p<0.001) and IgG4 responses to Hp (** p<0.01) in Al negative sera. Sample numbers were as follows Al−Tg− n=80; Al+Tg− n= 36; Al−Tg+ n= 30, Al+Tg+ n= 70. Bars represent standard error of the mean.
