Nodular purpura in infancy

Abstract

Summary: Seventeen infants with nodular purpura are reported. All these infants suffered from a coagulation abnormality due to vitamin K deficiency. Contributing factors were breast-feeding, the use of milk substitutes, diarrhoea and antimicrobial therapy. The patients responded rapidly and completely to parenteral vitamin K. In the management of infantile diarrhoea use of antibiotics should be restricted to specific bacteriologically proven cases.Vitamin K administration is suggested in infants with prolonged gastroenteritis and limited milk intake and particularly those receiving antibiotics.
