Q

Which diagnostic tests are implimented when investigating a case of CAD?

A

Serum IgE

Intradermal skin tests

Clinical signs - seasonal/ non-seasonal pruritis

Young dogs

17
Q

What are Favrots criteria for CAD?

A
  1. Under 3y/o
  2. Living mostly indoors
  3. Steroid responsive pruritis
  4. Front feet and ear pinnae affected (non-marginal)
  5. Dorso-lumbar area not affected
18
Q

Outline a potential management program for a dog suffering from cAD.

A
  1. Improve barrier function - nutritional and topical treatments
  2. Decrease flare factors - ectoparasite treatment, antiseptics (bacterial infection)
  3. Allergen vaccines - 60-70% success
  4. Anti-inflammatory drugs - eg steroids, apoquel
19
Q

How can barrier function be improved in cAD?

A
  • EFA diets - decreased water loss and improves coat
  • Topical emollients - transient decrease in pruritis
    • Allermyl - antimicrovial (piroctone, monosacc), anti-inflamm and anti-ox (vit E, linoleic acid)
20
Q

What is the MOA of Oclacitinib?

Where is its use contraindicated?

A

JAK inhibitor - decreases interleukins (JAK1), decreased haematopoiesis (JAK2)

Contraindicated - <12mo, <3kg BW, breeding, neoplasia, immunosupressed

4-8 weeks

Adverse effects - Increase hair (anagen), increased tear production, gum hyperplasia

22
Q

Name three drugs which interfere with ciclosporins mechanism of action.

A
  • Inhibit metabolism - azole, steroids
  • Increased metabolism - rifampin, phenobarb
  • Other - omeprazole, tramadol, ivermectin
