Gold standard of malaria diagnosis is </p><p> demonstration of parasite in the peripheral blood smear . However there </p><p> seems to be a co-relation between platelet count , the WBC counts , Hb , </p><p>PCV and morphology of RBC in malaria . The aim of this study is therefore </p><p> to make a thorough inventory of the haematological indices in peripheral </p><p> blood detected positive for malarial parasites in a group of 100 cases.</p><p>6.2 Review of Literature</p><p>There seems to be monocytosis and anaemia in chronic malaria . Anaemia</p><p> progressively becomes moderate to severe . Thrombocytopenia also seems to</p><p> be a feature during malaria . ‘ Vivax’ associated thrombocytopenia is</p><p> common [1] , with multiple mechanisms resulting in peripheral destruction</p><p> and splenic sequestration [2] , the role of platelet activation , microvascular</p><p>3 aggregation and microthrombotic processes in platelet destruction in severe vivax are not understood clearly [3]. Previous studies demonstrated an increase of neutrophil count during the first two days of fever due to falciparum malaria and subsequent decrease [4] . However , other reports showed lymphopenia in some cases of acute malaria [5],[6]. PCV</p><p>(hematocrit) is usually normal during the first 24 hrs after onset of fever , the PCV continues to fall for some days after antimalarial therapy [7]. A community based study of malaria prevention in Tanzania [8] has confirmed that falciparum malaria was an important cause of childhood anaemia with</p><p>PCV falls. Severe anaemia is common among pregnant women infected with falciparum [9]. Two possible causes of this anemia are increased hemolysis or a decreased rate of erythrocyte production [10],[11].Finally , infected erythrocytes may adhere to platelets , and clumps of infected erythrocytes and platelets have been associated with severe disease [12].</p><p>Since there are clues that monocytosis, thrombocytopenia are associated with malaria and little is known about RBC morphology and PCV in malaria , the aim is to study and make a complete inventory of the various Haematological indices in malaria patients.</p><p>4 6.3 Objectives of the study</p><p>1. To study the Hb , PCV and morphology of RBCs in smears detected</p><p> positive with malaria.</p><p>2. To make a Total count and Differencial count of WBCs in the peripheral</p><p> smears of malaria patients.</p><p>3. To establish a relationship of thrombocytopenia with malaria.</p><p>7. Material and methods:</p><p>7.1 Source of data.</p><p>All peripheral smear slides subjected for malarial parasite detection</p><p> tested positive in Central Diagnostic Lab (CDL) of AJIMS, Mangalore. 100</p><p> cases will be included in this study.</p><p>7.2 Method of collection of data ( including sampling procedure, if any)</p><p>4 ml of blood is collected from the patient using sterile aseptic methods in</p><p> an EDTA vacutainer. The blood drawn is fed into the automated cell counter</p><p> where the Hb , PCV and Total counts of the WBCs are collected, with the</p><p> remaining blood peripheral smears are made which are subjected to</p><p>5 leishman’s staining. The smears are evaluated and the RBC morphology ,</p><p> differencial count of WBCs and platelet counts are done. Informed consent</p><p> of the patient for the present study is required and is duly enclosed.</p><p>Inclusion criteria: All slides of malarial parasites tested positive after</p><p> peripheral smear examination.</p><p>Exclusion criteria: Slides not having malarial parasites.</p><p>Plan for data analysis:</p><p>Statistical analysis will be done .</p><p>7.3 Does the study require any investigations or interventions to be</p><p> conducted on patients or other humans or animals? If so, please describe</p><p> briefly? – No, once the blood is drawn no more interventions are required.</p><p>7.4 Has ethical clearance been obtained from your institution: </p><p>Yes 8 LIST OF REFERENCES </p><p>1.
