Abstract

PURPOSE: There are many causes of hematochezia in neonates and during early infancy. Cow`s milk allergy is considered to be the most common cause of bloody stools in infants; however, cow`s milk allergy is diagnosed in relatively few patients. In a significant proportion of case investigations, the etiology of hematochezia is not determined. The objectives of this study were to evaluate the clinical course and prognosis of patients with hematochezia of unknown etiology.
METHODS
The patients were <4-month-old infants with hematochezia in whom infectious and surgical etiologies had been excluded. We investigate retrospectively the clinical course and laboratory finding. We also perform 2-years follow-up study and evaluate prognosis of the patients.
RESULTS
In all study patients, RAST milk was negative. All patients had self-limited hematochezia. In 2-years of follow-up, the prognosis of patients was good. There were no differences at 2-year regarding allergic tendencies of the patients, as determined by the increase in total eosinophil count.
CONCLUSION
Hematochezia in neonates and during early infancy is generally a benign and self-limiting symptom. Based on 2-years of follow-up, the prognosis of the patients is good.
