Slide 2

Introduction Leukocytes capacity to ensure the body against remote life forms or antigens. In doing as such, they experience unmistakable changes that can be identified and assessed large scale and infinitesimally. The progressions fall into two classifications: Quantitative or large scale changes adjustments in quantities of cells Absolute Relative Qualitative or miniaturized scale changes modifications in cell morphology Nucleus Cytoplasm Graphic got to http://home13.inet.tele.dk/gloerud/yellow_l.gif , 2008.

Quantitative WBC Disorders

Slide 4

Definitions White Cell Numbers Leuko cytosis: increment in the quantities of flowing white cells >12,000/uL Leukopenia: diminish in the quantities of coursing white cells < 4,000/uL Left Shift – expanded circling quantities of juvenile neutrophils Leukoerythroblastic Reaction – leukocytosis with a left move joined by nucleated red cells: found in threat . Leukemoid Reaction – kindhearted unnecessary leukocytosis joined by a misrepresented neutrophilia and a left move in light of a disease ; the WBC > 50 x 10 9/L Leukocyte Alkaline Phosphatase – stain used to separate a leukemoid from a leukoerythroblastic response Graphics got to URL http://atlasgeneticsoncology.org/Anomalies/t0422q12q11ID1153.html & http://www.med-ed.virginia.edu/courses/way/innes/wcd/leukocytosis.cfm , 2010. http://www.med-ed.virginia.edu/courses/way/innes/pictures/wcdjpeg/wcd%20leuko%20Eblastic%20x50.jpeg

Pathophysiology

Slide 8

Eosinophilia Absolute check >0.5 x 10 9/L Causes: parasites Helminths drug medicines hypersensitivities diseases neoplasms CML immune system issue

Basophilia Absolute tally >0.15 x 10 9/L Causes: CML sensitivities incendiary issue illumination viral contaminations Graphic got to URL http://healthsystem.virginia.edu/web/hematology/HessImages/Mature-basophils-100x-site arrow.jpg , 2006.

Slide 10

Monocytosis Absolute check > 0.8 x 10 9/L Most generally found in conditions with expanded cell harm - Chronic disease [TB, syphilis, protozoal contaminations, rickettsial infections] Recovery from agranulocytosis Post-splenectomy Strenuous activity Subacute bacterial endocarditis

Slide 11

Definition: not exactly the ordinary outright number; extraordinarily impacted by patient age and race. African and Middle Eastern populaces Subclasses incorporate mellow, direct and extreme Causes Reactions to Drugs BM ablative treatment Infections HIV/Hepatitis Typhoid/miliary TB Malaria Immune Disorders SLE Neoplasm BM Failure Megaloblastic Anemia Aplastic Anemia Hypersplenism Idiopathic Neutropenia < 2.5 x 10 9/L

Slide 12

Neutropenia Pathophysiology Defects inside or outside the Bone Marrow Decreased multiplication [failure of cells - aplasia] Decreased development [insufficient number of forerunners experiencing irregular maturation] Decreased survival [increased decimation and/or quick expulsion of cells] Distribution [total body pools are ordinary, flowing numbers are reduced]

Slide 13

Normally: 60-80% coursing lymphs are T-cells [2:1 CD4/CD8] 10-20% are B-lymphs 5-10% are common executioner or NK cells Causes Infections Viral Infectious mononucleosis Bacterial Pertussis Thyrotoxicosis Recovery from intense diseases Neoplasm Leukemias Lymphomas Lymphocytosis Absolute check > 5.5 x 10 9/L

Slide 14

Infectious Mononucleosis Acute, self-restricting, febrile contamination of B-cells Circulating receptive lymphocytes are essential CD8 T-cells Typically happens in those age 10-25 years Fever Sore throat Lymphadenopathy Lethargy Positive serology – Heterophile antibodies Graphic got to URL http://www.md.huji.ac.il/mirror/webpath/HEME013.jpg , 2005.

Slide 15

Lymphopenia Absolute lymphocyte check <0.6 x 10 9/L There are three sorts of irregularities: Decreased creation Increased pulverization Changes in dispersion

Slide 16

Decreased generation SCID = extreme consolidated immunodeficiency Protein-calorie ailing health Zinc lack Increased annihilation HIV disease Radiation treatment Neoplastic chemotherapy SLE Redistribution Glucocorticoid treatment Anesthesia TB Influenza Burns Other Hodgkin\'s Myasthenia gravis Lym pho pen ia

Altered Cell Morphology Nuclear Pelger-Huet Hypersegmentation Cytoplasmic Alder-Reilly Chediak-Higashi May-Hegglin Gaucher Niemann-Pick Mucopolysacchridoses Toxic Granulation Vacuolization Dohle Bodies Necrobiosis Think Neutrophilia because of Severe Bacterial Infection Peripheral Blood, Wright\'s, 100x.

Slide 19

Pelger Huet – an acquired condition bringing about hyposegmentation of granulocyte cores with expanded thickness and coarseness of the chromatin. . Try not to mistake this inconsistency for a neutrophilic left move! May-Hegglin - an uncommon disorder described by leukopenia, variable thrombocytopenia, GIANT PLATELETS , and dim blue cytoplasmic considerations in the neutrophils and monocytes [dohle-like bodies] Definitions

Slide 20

Alder-Reilly - an acquired characteristic portrayed by the nearness of anomalous extensive azurophilic and basophilic granules looking like neutrophilic harmful granulation. Chediak-Higashi - is a hereditary issue that has a comparable disorder in mink, dairy cattle, mice, felines, & executioner whales. Influenced people show fractional albinism, are exceptionally defenseless to regular irresistible operators, and have white cells exhibiting goliath cytoplasmic granules. Definitions

Slide 21

Gaucher & Niemann-Pick are portrayed by the absence of or inadequate action of chemicals. In Gaucher infection, there is an absence of beta-glucocerebrosidase and macrophages get to be loaded down with glucocerebrosides. In Niemann-Pick, there is lacking action of lysosomal hydrolase and sphingomyelinase bringing about the gathering of cholesterol and sphingomyelin in mononuclear phagocytes. Mucopolysaccharidoses are a gathering of hereditarily decided inadequacies of particular proteins required in the corruption of mucopolysaccharides .

Dohle Bodies and Necrobiosis Single or numerous blue cytoplasmic incorporations. They speak to leftovers of harsh endoplasmic reticulum from prior maturational stages. They are connected with myeloid "left shifts" and are found in conjunction with dangerous granulation. Necrobiotic WBC shows atomic debasement or karyorrhexis. Demonstrates cell demise in chemotherapy or an ineffectively safeguarded example. (From Carr JH, Rodak BF: Clinical Hematology Atlas, second ed. Philadelphia: Saunders, 2004.)
