Guar gum is a food additive that acts as a thickening agent. Although the relationship between guar gum and occupational rhinitis/asthma has already been established, only very few cases of anaphylaxis were associated with guar gum ingestion. We present two examples of anaphylaxis induced by guar gum. Both cases were successfully treated with adrenaline. Moreover, serum-specific immunoglobulin E (IgE) with the culprit agent was detected in blood samples. To the best of our knowledge, here we present the first case of class 6 guar gum-specific IgE-positive anaphylaxis. This report aims to raise awareness of rare food additive allergies such as guar gum.
Chronic hepatitis B and hepatitis C infections are major health problems in the world. Therefore, prevention of the transmission of the viral infections gets higher priority. Development of hepatitis B vaccines by recombinant technology provide higher prevention rates. However, this success could not be achieved with hepatitis C vaccine. The present review discusses recent developments for hepatitis B and C vaccines.

ÖZKronik Hepatit B ve C enfeksiyonları tüm dünyada major bir sağlık sorunudur. Bu nedenle enfeksiyonun geçişinin önlenmesi büyük önem kazanmaktadır. Rekombinant yol ile geliştirilen Hepatit B aşısı ile çok başarılı koruyuculuk sağlanırken, aynı başarı Hepatit C enfeksiyonu için geliştirilen aşı çalışmalarında gerçekleştirilememiştir. Bu derlemede hepatit B ve C enfeksiyonları için geliştirilen aşı çalışmaları hakkında son gelişmeleri tartışılmıştır.
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.
