ABSTRACT
Background: Malaria is a numero-uno infectious, killer disease in the developing world including India. This disease is caused by Plasmodium parasitic species with mosquitoes acting as vectors of transmission. Hematological tests include RBC, WBC and platelet parameters, peripheral blood examination which change based on parasitaemia need to be evaluated in various malaria affected regions to get prompt malarial diagnosis. Prompt diagnosis leads to prompt treatment avoiding troublesome malarial complications. Objectives: The present observational cross-sectional study was undertaken to estimate the Hematological profile in malaria cases diagnosed in a tertiary care hospital of Konkan region, Maharashtra. Methods: All the patients referred to Hematology section, Department of Pathology with malaria were evaluated with clinical details. The data was collected from 1st January 2017 to 31st December 2020 for three years’ duration. Total malarial cases studied were 50 cases. CBC/ PBS examination was done on EDTA blood sample. The RBC parameters, WBC parameters and platelet counts were studied with respect to malarial parasitaemia. Parasite index was found on smear and malarial diagnostic confirmation was also done using rapid kit test. All the findings were filled in MS-Xcel sheet 2010 and data was analyzed manually. Results: Malaria caused by P.vivax was predominant in present study. Patients in age range of 15-30 years were more affected in present study, that is, younger people were affected. Male predominance was seen. Fever was most common presenting symptoms followed by chills and rigor in present study. Hb, RBC count, PCV – showed that anemia was more common hematological change in present study, as these values were lower than normal level. Red cell indices like MCV, MCH, MCHC, RDW and peripheral blood smear revealed all the values in a normal range showing normocytic normochromic RBCs in the present study. Patients with malaria having normal TLC followed by leucopenia were more common in present study. Thrombocytopenia was most common hematological change seen in present study. Conclusion: Hematological parameters are measurable indices of blood that serve as a marker for malarial diagnosis.
ABSTRACT
The objective of this study was to measure the effects of glucose and salt level on white blood cells, red blood cells and platelets (PLTs) in the blood of a leukemic patient by using a white light microscope. Different concentrations of glucose and salt in the range of 0 mM to 500 mM were admixed in the blood sample to prepare blood smear. We revealed that shape of erythrocytes, leukocytes and platelets changes and form aggregates. Increasing concentrations of glucose cause to increases aggregation process of white blood cells, red blood cells and platelets. And the increasing concentration of sodium chloride causes to increase rouleaux formation and aggregation of platelets but dehydration due to increased sodium chloride concentration causes to break the aggregation of white blood cells. Comparison of CBC reports of these samples with and without analytes shows that total leukocyte count (TLC) decreases gradually towards normal ranges of leukocytes which is favorable in the treatment of leukemia but at the same time decreasing level of hemoglobin HGB, mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and increasing level of red blood cell (RBCs) causes to reduce oxygen supply which is in favor of cancer growth and anemia. This work provides us the base for translation this in vitro study towards the in vivo case of blood microvasculature as a non-invasive methodology.
O objetivo deste estudo foi medir os efeitos da glicose e do nível de sal nos glóbulos brancos, glóbulos vermelhos e plaquetas (PLTs) no sangue de um paciente leucêmico usando um microscópio de luz branca. Foram misturadas diferentes concentrações de glicose e sal na gama de 0 mM a 500 mM na amostra de sangue para preparar esfregaço de sangue. Descrevemos que a forma dos eritrócitos, leucócitos e plaquetas muda e forma agregados. O aumento das concentrações de glicose aumenta o processo de agregação de glóbulos brancos, glóbulos vermelhos e plaquetas. E a crescente concentração de cloreto de sódio causa o aumento da formação de rouleaux e a agregação de plaquetas, mas a desidratação devido ao aumento da concentração de cloreto de sódio causa a quebra da agregação de glóbulos brancos. A comparação dos relatórios de CBC dessas amostras com e sem analitos mostra que a contagem total de leucócitos (TLC) diminui gradualmente para os intervalos normais de leucócitos, o que é favorável no tratamento da leucemia, mas ao mesmo tempo diminui o nível de hemoglobina HGB, hemoglobina corpuscular média (MCH ), a concentração média de hemoglobina corpuscular (MCHC) e o aumento do nível de glóbulos vermelhos (RBCs) reduz o suprimento de oxigênio, o que é a favor do crescimento do câncer e da anemia. Este trabalho fornece a base para a tradução deste estudo in vitro para o caso in vivo de microvasculatura de sangue como uma metodologia não-invasiva.
