Quiz
Which of the following statements regarding IMHA is FALSE?
(Required)
It is characterized by the destruction of erythrocytes that have been coated with immunoglobulins
Immunoglobulins may be directed either against the normal erythrocyte or an antigenically modified erythrocyte
A genetic predisposition is evident in cats
Immunoglobulins are directed against the normal components of the erythrocyte membrane
Female dogs appeared to be predisposed
Which of the following has NOT YET been associated with IMHA?
(Required)
Hyperadrenocortism
Intestinal helminths
Cephalosporin antibiotics
Babesiosis
Beestings
Which of the following statements regarding the pathophysiology of IMHA is INCORRECT?
(Required)
The degree of erythrocyte lysis depends on the type and amount of immunoglobulin that binds to the erythrocyte membrane
The neutrophil is mainly responsible for phagocytosis of the erythrocyte
Erythrophagocytosis occurs in the liver
Complement activation causes an immediate intravascular lysis
Partial erythrophagocytosis results in the formation of spherocytes
Which of the following regarding spherocytes is INCORRECT?
(Required)
They are spherical erythrocytes that appear microcytic with no central pallor
They can occur with hypophosphatemia and zinc intoxication
They are commonly seen in dogs with splenic hemangiosarcoma
They can be hereditary
They are easily identifiable on a blood smear examination in both the dog and cat
Which of the following test/procedures would NOT be appropriate in the initial assessment of a dog that has been diagnosed with IMHA?
(Required)
Faecal analysis
Survey thoracic radiographs
Abdominal ultrasonography
ANA titre
Urine culture
Which of the following tests would lead to a definitive diagnosis of IMHA?
(Required)
Presence of spherocytosis
Positive Coombs’ test
Low haematocrit
Presence of haemoglobinaemia
Which of the following is not a TYPICAL serum biochemical abnormality associated with IMHA?
(Required)
Hemoglobinemia
Hypercholesterolemia
Hyperbilirubinemia
Elevated serum urea
Elevated liver enzyme activity
Which of the following is NOT regarded as poor prognostic indicator in a dog with IMHA?
(Required)
Elevated serum bilirubin concentration
Presence of non-regenerative anemia
Persistent auto-agglutination
High spherocyte percentage
Development of thromboembolic complications
Which of the following should NOT be used in the routine supportive therapy of dog with primary IMHA?
(Required)
Anticoagulant therapy
Gastric protectants
Fluid therapy
Blood transfusion
Antibiotics
In a dog with IMHA that is not responding to prednisolone therapy, the MOST appropriate add-on drug would be:
