Non-malignant WBC Disorders Flashcards
Neutrophilia
Increased neutrophils >7.0 x 10^9/L
Not pathogenic (usually)
Exercise, anesthesia, newborn
Pseudoneutrophilia
No increase in bands
Redistribution of MGP and CGP
Acute Neutrophilia
Bacterial infection/toxin
Bone marrow response (shift left)
10-20 K
Chronic Neutrophilia
Continuous stimulation
Bone marrow storage depletion
Toxic granulation with Dohle bodies
Bacterial infection
Leukemoid Reaction
Extreme reaction to severe infection
Necrotic tissue
Usually >25k
Many immature cells
Leukemoid Reaction Lab Results
Normal RBC
Normal Platelet
Toxic granulation
Dohle Bodies
LAP increased
Neutrophilia Other Causes
Tissue necrosis
Burns
Rheumatoid arthritis
Tumors
Steroids
Pregnancy
Neutropenia
<2.0 x 10^9/L of 1.5 x 10^9/L
Decreased Bone Marrow production
Stem cell disorders
Neutropenia Causes
Radiation
Chemotherapy
Myleophthisic anemia
Megaloblastic anemia
Inherited disorders
Increased WBC loss
Severe infection
Immune loss
Hypersplenism
Hemodialysis
Viral infection
Pseudoneutropenia
Increase in MGP
Transient
Agranulocytosis
<0.5 x 10^9/L
Possibility of severe infection
Chronic Granulomatous Disease
Inherited
Abnormal Oxidative metabolism
Recurrent infections
Nitroblue tetrazolium test (NBT)
Chediak Higashi Anomaly
Inherited
Fusion of primary and secondary granules
Abnormal lysosomes
Hypopigmentation
Death in infancy
May-Hegglin Anomaly
Inherited
Large basophilic inclusions in cytoplasm
+/- Thrombocytopenia
+/- Bleeding
Pelger-Huet Anomaly
Benign, Inherited
Hyposegmentation (bi-lobed segs and inc bands)
Pince nez cells (old spectacle look)
Normal Cell function
Alder Reilly Anomaly
Inherited
Large, purple granules in WBC cytoplasm
Enzyme deficiency
Cells appear as clusters and may have vacuoles
Normal cell function
