83 burn patients with the syndrome of bacterial infection and intoxication associated with leucopenia were divided in to 2 groups, the one of 32 patients without transfusion of white blood granulocyte, the other 51 patients with a transfusion rich with neutrophile leucocyte. Results: In the group of the syndrome of severe bacterial infection and intoxication associated with leucopenia, 39.2% have had complication, less than no transfusion group (68.7%). Mortality of the transfusion group: 82.4%, is higher than no transfusion group: 40.6%

We found an unusual morphology of eosinophil nucleus having longer chromatin filament in addition to a single narrow chromatin bridge. The nucleus having two chromatin filament bridge looked like two legged eosinophil, instead of usual glasses shape. As the physiologic function of the nucleus of granulocyte segmentation and the mechanism by which the lobes are formed during differention is still unknown, we could not know the definite nature and significance of these double chromatin filament. However we could suggest that they may be a reactive change of eosinophilia. This not uncommon morphology has not been described as yet. Here we report three cases of unusual morphology of eosinophil nucleus presenting double chromatin filament bridge, one case with a band form nucleus looked like ring shape, with brief review of literatures.

Agranulocytosis as a side effect of clozapine has been reported to be associated with initial phases of treatment, i.e., first six months. Agranulocytosis with clozapine during the initial phases of treatment has been linked to genetic vulnerability in the form of variations in the human leukocyte-antigen haplotypes. However, there is limited literature on late onset agranulocytosis with clozapine and this has very rarely been linked to human leukocyte-antigen haplotypes vulnerability. In this report we review the existing data on late onset agranulocytosis with clozapine and describe the case of a young man, who developed agranulocytosis with clozapine after 35 months of treatment and was found to have genetic vulnerability in form of being positive for HLA DR4. This case highlights underlying autoimmune immune mechanism in clozapine-induced agranulocytosis and the need for frequent blood count monitoring on clozapine even after the initial 6 months of starting treatment especially in patients with genetic vulnerability to develop this condition.

INTRODUCTION: The ABX Pentra DX 120 (Pentra DX 120, ABX Diagnostics, Montpellier, France) adopted new technologies to perform differential leukocyte and erythroblast counts. The double matrix can discriminate Large Immature Cell (LIC), Immature Granulocyte (IMG), Immature Monocyte (IMM), Immature Lymphocyte (IML), and Atypical lymphocyte (ALY) in addition to a routine 5-differential count. For erythroblast (ERB), a fluorescence method is employed. In this study, we evaluated the performance of the Pentra DX 120 in the performance of differential leukocyte and erythroblast counts. METHODS: Precision was evaluated using 3-level control materials. Comparison analysis was performed on 200 samples: 100 normal and 100 abnormal samples. We evaluated the 5 part differential count, LIC, IMG, IMM, IML, ALY, and ERB. These parameters were analyzed in comparison with the results from the reference method, manual differential count. RESULTS: The coefficients of variation (CVs) of precision were <5% for neutrophils and lymphocytes, <15% for eosinophils and basophils and <7% for erythroblasts. The correlation coefficients (r) were >0.9 except monocytes and basophils. IMG, ALY and erythroblasts were also well correlated with manual count (r=0.8315, 0.5602, 0.8144, respectively). The efficiency of flagging system was 84% for LIC, 80% for ALY, and 78.0% for increased ERB (>2/100WBCs). CONCLUSIONS: The Pentra DX 120 performed reliable differential leukocyte and IMG, ALY, and ERB results demonstrated comparable performance to manual count. And, the flagging system was efficient for detecting each abnormal cell population. We expect the Pentra DX 120 double matrix and erythroblast count can reduce microscopic review rate in routine laboratory and promote laboratory efficiency.
