Abstract
BACKGROUND
Delta-He the difference between hemoglobin content in reticulocytes and erytrocytes is a relatively new laboratory indicator that is easily measured in everyday practice. This parameter is directly related to iron bioavailability for hemoglobin synthesis and can reflect various conditions accompanied by cytokine expression including systemic inflammation.
OBJECTIVE
To analyze the prospects for practical application of hemoglobin delta in assessment of neurosurgical patients throughout in-hospital treatment.
MATERIAL AND METHODS
We analyzed complete blood counts (Sysmex XN-1000 analyzer) with optical determination of reticulocyte hemoglobin and automatic calculation of Delta-He in 82 neurosurgical patients. Exclusion criteria were severe decompensated comorbidities, exacerbation of chronic infectious processes, cancer of other organs. Blood sampling for analysis of delta-hemoglobin was carried out before all diagnostic and therapeutic measures. Reference interval is indicated by the analyzer manufacturer as 1.7-4.4 pg.
RESULTS
Delta-He values at admission ranged from -1.8 to 6.1 pg. There was a consistent decrease of these values throughout 3-4 postoperative days. Then, the values could increase or continued to decrease. Increment of the index was noted in 76 patients (92.7%). Such dynamics was observed in case of uncomplicated postoperative period. Further decrease of Delta-He was observed in 6 patients (7.3%). These ones were characterized by a longer recovery after surgery, and the events required additional medical or surgical correction were recorded. Negative dynamics of Delta-He values could precede clinical manifestations of certain complication. Clarification of diagnosis and correction of therapy were accompanied by gradual increase of Delta-He values.
CONCLUSION
Estimation of Delta-He values over time can be used for monitoring of patients and effectiveness of therapy. From a practical point of view, it is important that examination can be performed at any time of the day.
