The aim of the study was to identify the relationship of acquired neutropenias with infections in childhood and to assess their course, complications, short and long-term outcome.


During a two-year period, all children admitted to the pediatric ward with neutropenia were investigated for underlying infections with indices of infection, cultures of body fluids and serological tests.


Sixty-seven previously healthy children, aged (median, 25-75%) 0.7 years (0.2-1.5), were identified with neutropenia (frequency: 2.0%). An infectious agent was identified in 34/67 cases (50.7%) (viral infection: n=24, bacterial: n=10). In 50/67 (74.6%) children, neutropenia recovered within 2 months (transient neutropenia, TN), while in 17/67 (25.4%) of them it persisted for more than two months. Two years after diagnosis 50/67 children (74.6%) accepted to be reassessed. Of these children, 8/50 (16%) remained neutropenic (neutropenic children, NC), while 42/50 had recovered completely.


Neutropenia during childhood is usually transient, often following viral and common bacterial infections, does not present serious complications and in the majority, it resolves spontaneously. However, in a significant percentage of patients, neutropenia is discovered during the course of an infection, on a ground of a preceding chronic neutropenic status.
