Treatment of a patient with clinical features of both eosinophilic gastroenteritis and polyarteritis nodosa with oral sodium cromoglycate.

A young patient who suffered from allergic respiratory disease presented with an illness characterized by abdominal pain, diarrhea, and weight loss. Investigations revealed radiological and pathological features consistent with a diagnosis of eosinophilic gastroenteritis. Because of extensive gastric ulceration, treatment with corticosteroids was withheld and in its place oral sodium cromoglycate therapy given. The patient's intestinal symptoms rapidly responded to this treatment and remained controlled for a period of five months. The patient subsequently developed a systemic illness with features of polyarteritis nodosa.
