and 1 had methylmalonic aciduria). Average duration of neutropenia was 6,43 months while average age at diagnosis was 19,6 months. During this study 227 (78,82%) examinees were cured, 34 (11,81%) were still being followed up and for 27 (9,38%) of them we didn't know outcome. 39,24% neutropenias were acute and 56,25% were chronic. According to the severity of neutropenia the distribution was 60,42% -26,39% -12,85% (severe, moderate, mild). Average duration of neutropenia in cases of severe neutropenia (ANC < 0,5 x 10 9 /l) was 9,14 months, in moderate neutropenia (ANC = 0,5-1,0 x 10 9 /l) 4,09 months and in mild neutropenia (ANC > 1,0 x 10 9 /l) 1,64 months. We recorded infection during neutropenia in 232 (80,56%) examinees while 88 (30,56%) had noted infections before the onset of neutropenia. Conclusion This study showed that 97,57% children had benign neutropenia and 78,82% were spontaneously cured during the research which are encouraging results. We noted that children with mild neutropenias and those who had no recorded infections during neutropenia had shorter average duration of neutropenia. In conclusion, most neutropenias of the early childhood are benign and have favorable outcome.
