Does [ Functional Dyspepsia and infection by Helicobacter pylori : a causal relation exist ]?
1) There would be an overestimation of UGE value in presumable dyspeptic patients, 2) Prevalence of infection agrees with the published values in equivalent populations in our country, 3) Pinfection prevalence was greater in men. 4) It could exist significative differences between age of symptoms onset in infected group (earlier symptoms) and means of age (younger infected people at the moment of this study), but there were very wide data dispersion), 5) Association between age and positiveness would be explained because it would be an accumulative phenomenon noted by us in a previous study 6) There wouldn't be enough evidence to consider Hp infection to be the cause of NUD.
Recipient cytokine release induced by blood transfusion seems to be dependent on storage time. This may have implications in transfusion-induced immune modulation.
