Growth failure due to protein loss in dermatitis.

A 10-month-old infant is described who suffered from extensive atopic dermatitis, failure to thrive, hypoalbuminaemia and oedema. Large amounts of sticky exudate were lost through the skin and were shown to be rich in albumin. As renal and intestinal loss of protein was excluded, the patient's condition was ascribed to the loss of albumin through the skin at a rate that out-stripped the synthesis of this protein. Treatment with steroids resulted in dramatic clearing of his dermatitis, and subsequent rapid correction of his hypoalbuminaemia, oedema and anaemia.
