ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the value of mean corpuscular volume/RBC distribution width (MCV/RDW) combined with reticulocyte parameters in differential diagnosis of aplastic anemia (AA), myelodysplastic syndrome (MDS), megaloblastic anemia (MA) and hemolytic anemia (HA) in order to provide some laboratorial evidence for clinical doctors in first diagnosis of these diseases.</p><p><b>METHODS</b>The data of MCV/RDW and reticulocyte parameters of AA, MDS, MA and HA patients from January 1 of 2011 to August 31 of 2014 were retrospectively collected in West China Hospital of Sichuan University. And 158 healthy unrelated individuals with age-, sex-matched were collected as controls. The value of MCV/RDW and reticulocyte parameters in differentiating diagnosis of above mentioned 4 kinds of anemia diseases was assessed. ROC analysis was used to determine the cutoff value of MCV/RDW and the reticulocyte parameters were performed in differentiating diagnosis of AA and MDS.</p><p><b>RESULTS</b>The average values of MCV/RDW of 158 AA patients (79 acute AA patients and 79 chronic AA patients), 107 MDS patients, 13 MA patients and 81 HA patients increased in variable degrees as compared with the controls, and there was statistical difference between them, the MCV/RDW value of acute AA patients was obviously less than that of other patients. In the 4 kinds of anemia diseases, the reticulocyte absolute count in acute AA patients was the lowest, that of chronic AA, MA and MDS patients was higher, and that of HA patients was highest. The ratio of low fluorescent reticulocyte decreased, and the ratio of moderate and high fluorescent reticulocytes increased in the 4 kinds of anemia diseases, as compared to controls. The difference was statistically significant. The analysis of differential diagnosis of chronic AA and MDS showed that RDW-SD could differentiate the chronic AA from MDS. The area under the curve (AUC) of RDW-SD was 0.76 (P < 0.01). The cutoff value of RDW-SD was 22.75fl. The sensitivity and specificity of RDW-SD for differential of chronic AA and MDS was 49.5% and 98.7%, respectively.</p><p><b>CONCLUSION</b>MCV/RDW and reticulocyte parameters can be used as the laboratorial differential diagnostic indicators for AA, MDS, MA and HA diseases.</p>
