Hematological alteration among visceral leishmaniasis patients attending in Western Tigrai, Ethiopia, 2018/2019: A cross-sectional study

Abstract Background: Hematological abnormalities are common in visceral leishmaniasis patients, which is one of the main public health problems worldwide. The most common hematological abnormalities are anemia, leucopenia and thrombocytopenia. Therefore, this study aimed to assess the hematological alteration among visceral leishmaniasis patients attending Western Tigrai, Ethiopia, 2019. Method: Hospital based comparative cross sectional study was conducted from November 2018 to March 2019 in Western Tigrai, Ethiopia. A total of 100 Visceral Leishmaniasis patients and 100 control groups were included in this study. Blood was collected and analyzed by mindray BC-5800 hematology analyzer. Data was entered and analyzed using Statistical package for social science version 23. Student independent t-test was used for data analysis. P value <0.05 was considered as statistically significant at 95% confidence level. Result: From the total 100 visceral leishmaniasis patients the following abnormalities were reported: 96(96%) anemia, 95(95%) leucopenia, 92(92%) neutropenia, 73(73%) Lymphopenia, 45(45%) eosinopenia and 97(97%) had thrombocytopenia. Red blood cell, hemoglobin, hematocrit, red cell indices and platelet were significantly lower (p<0.05) in visceral leishmaniasis patients compared with the control groups. Similarly the total White blood cell, neutrophil, lymphocyte, eosinophil and basophil count were significantly lower (p<0.05) in visceral leishmaniasis patients compared with the control groups. Conclusion: The major changes in peripheral blood of patient with visceral leishmaniasis are reduced number of red blood cells, reduction in leukocytes and decreased platelet count. Visceral leishmaniasis patients presented with anemia, leucopenia and thrombocytopenia. So this finding indicates that visceral leishmaniasis causes alterations of hematological parameters.
