Neutropenia is usually detected shortly after birth, affecting 6% to 8% of all newborns in neonatal intensive care units (NICUs). Out of the approximately 600,000 neonates annually treated in NICUs in the United States, 48,000 may be diagnosed as neutropenic. The incidence of neutropenia is greater in premature infants. Six to fifty-eight percent of preterm neonates are diagnosed with this auto-immune disease. The incidence of neutropenia correlates with decreasing birth weight. The disorder is seen up to 38% in infants that weigh less than 1000g, 13% in infants weighing less than 2500g, and 3% of term infants weighing more than 2500 g. Neutropenia is often temporary, affecting most newborns in only first few days after birth. In others, it becomes more severe and chronic indicating a deficiency in innate immunity. Furthermore, the prevalence of chronic neutropenia in the general public is rare. In a study conducted in Denmark, over 370,000 people were assessed for the presence of neutropenia. Results published demonstrated only 1% of those evaluated were neutropenic, and were commonly seen in those suffering from HIV, viral infections, acute leukemias, and myelodysplastic syndromes. The study concluded the presence of neutropenia is an ominous sign that warrants further investigation and follow-up.
