Biologics against interleukin-5 were administered to five patients with eosinophilic gastroenteritis (EGE) and bronchial asthma (BA). BA and abdominal symptoms as well as changes in steroid dose and the blood eosinophil count were examined. The man-to-woman ratio was 1:4. The average age of onset was 63 years old. The duration of the disease was three to nine years. Four patients showed improved BA symptoms with mepolizumab or benralizumab, and three successfully discontinued steroids. Regarding abdominal symptoms, mepolizumab was effective in one of three cases, while benralizumab improved symptoms in three of four cases. Biologics targeting interleukin-5 are effective in some patients with EGE accompanied by BA.
