clin path 8 Flashcards
main causes of neutrophilia
stress-cortisol-mediated)
excitement or physiologic (epinephrine-mediated)
inflammation
stress neutrophilia
storage pool release
marginal to circulating
stress neutrophilia cbc and chem
hours to days to develop
mild neutrophilia (<2x URL)
no left shift
lymphopenia (best support)
hyperglycemia (related to cortisol effects on insulin, glycogen, lipolysis
increased ALP activity (dog
excitment/physiologic neutrophilia
marginal to circulating
splenic contraction
increase heart rate
increase stroke volume
increased cardia output
excitement/physiologic neutrophil cbc and chem
immediate to about 30 minutes
mild neutrophilia (< 2x URL)
no left shift
mild lymphocytosis (different)
erythrocytosis (splenic contraction)
thromobocytosis (splenic contraction)
hyperglycemia (related to epinephrine effects)
inflammatory neutrophilia
maturation and storage release
recruit marginal pool
hyperplasia
inflammatory neutrophilia cbc and chem findings
neutrophil count >2x URL
concurrent left shift (different)
neutrophil toxic change
neutrophilia <2x URL without another obvious cause
concurrent lymphocytosis suggests chronic inflammation
Monocytosis (especially if lymphocyte count is normal or increased)
hyperfibrinogenemia with decreased PP:fibrinogen (large animal)
hyperglobulinemia
hypoalbuminemia
glucose
leukemoid repsonse
neutrophil numbers > 50,000/ul
subtype of chronic inflammation
causes of leukemoid reponse
IMHA with resulting tissue necrosis
the 6 P’s
neoplasia with necrotic portions of the tumor
the 6 p’s
pyometra, pyothorax, peritonitis, pyelonephritis, pneumonia, paraneoplastic
inflammation without neutrophilia
normal neutrophil numbers and a left shift
normal neutrophil numbers and a neutrophil toxic change
inflammatory neutropenia pathogenesis
utilization>production
inflammatory neutropenia conditions
severe infection/sepsis
acute inflammation (ruminants)
inflammatory neutropenia hematologic support-CBC and chemistry
left shift
toxic neutrophils
other lineages (RBC platelets unaffected)
lymphopenia
hypogylcemia
Decreased production neutropenia
myelosppressive agents/toxin
virus
bacteria
drugs
toxins
idiopathic
myelophthisis
myelitis
leukemia
myelofibrosis
