Comparison of hematological findings in H1N1 infections with hematological findings in other viral agents

Özet

Introduction: In this study, the hematologic findings of patients who were diagnosed with H1N1 virus infection and their effects on the course of the disease were reviewed. Method: Twenty-one children who received diagnosis of H1N1 infection were included in the study. Blood count results on days 1, 3 and 7 were examined. The frequency of the 1st day hematolo-gic findings of the patients was compared with those of 3 groups in the same age and the same number of patients. Time of onset of hematologic findings and prognostic effects were evaluated. Results: Seven of the 21 patients (33.3%) were female, and 14 (66.7%) were male. The mean age was 5.1 years. Seven patients (33.3%) had leukopenia, 3 (14.3%) had leukocytosis, and 4 (19%) had anemia. Nine patients (42.9%) had thrombocytopenia, and 1 patient (4.8%) had thrombocytosis. Lymphopenia was detected in 9 patients (42.9%), neutropenia in 3 (14.3%), and monocytosis in 8 patients (38.1%). Three patients who had underlying chronic disease or respiratory distress died during the follow-up period. Conclusion: In conclusion, more frequent and severe cytopenias seen in H1N1 infections are thought to cause the clinical presen-tation to be more severe.
