This article provides new insights on FPIES in Italy by describing its largest series, and shows how a significant increase in the FPIES diagnosis has been observed in the last few years. We also discussed selected management aspects of this syndrome where different phenotypes can be found.
Results: 13 of the 403 children had acquired hepatitis C virus infection at the end of follow up. All these children were born to women positive for hepatitis C virus RNA; none of the 128 RNA negative mothers passed on the infection (difference 5%, 95% confidence interval 2% to 7%). 6 children had viral RNA immediately after birth. 111 women had used intravenous drugs and 20 had received blood transfusions. 11 of the infected children were born to these women compared with 2 to the 144 with no known risk factor (difference 7%, 2% to 12%).
Conclusions:This study suggests that in women not infected with HIV only those with hepatitis C virus RNA are at risk of infecting their babies. Transmission does seem to occur in utero, and the rate of transmission is higher in women who have had blood transfusions or used intravenous drugs than in women with no known risk factor for infection.
In our area, foods, particularly seafood and milk, seem to be the most important etiologic factors triggering anaphylaxis. Food-induced anaphylaxis often occurs in younger children with a severe food allergy, whereas exercise-induced anaphylaxis occurs more often in older children with a history of urticaria-angioedema. The venom-induced variant usually presents itself in nonatopic subjects. Given the fact that most of the children had only one anaphylactic reaction, prevention is almost impossible. Epinephrine, although it is the first-choice treatment of anaphylaxis, often goes unused, even in hospitals and doctors' offices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
