24
Q

What is severe/fulimant CD?

Study These Flashcards
A

Symptoms persist with corticosteroids OR
high fever, vomiting, reboound tenderness, cachexia, evidence of intestinal obstruction / abcess

25
Which IBD has a higher risk of cancer?
UC
26
The risk of cancer starts to increase how many years after IBD diagnosis?
8 years
27
What are fistulas?
Abnormal communication between 2 organs or organ and exterior (intestines and bladder) usually areas of worst inflammation
28
Which IBD are fistulas more common?
CD
29
What is toxic megacolon?
severe inflammation, no peristalsis, emergency
30
What drugs increase the risk of toxic megacolon?
anticholinergics antispasmodics opioids other drugs that decrease peristalsis
31
What agents are used for induction and maintenance of IBD?
Aminosalicylates Budesonide Remicade
32
What agents are used only for IBD maintenance?
Thiopurines
33
What agents are used only for IBD induction?
Corticosteroids
34
What is a CI to Aminosalicylates?
Aspirin, salicylate allergy
35
What Aminosalicylate should be avoided in patients with a sulfa allergy?
Sulfasalazine
36
What are dose related ADEs with Sulfasalazine?
GI disturbance, headache, arthalgia
37
What are ADEs that happen at any dose of Sulfasalazine?
rash, fever, hepatotoxicity, nephrotoxicity, bone marrow suppression, discoloration of skin, urine,and other secretions
38
What needs to be monitored while taking Aminosalicylates?
LFTs, renal function (CrCl, SCr, BUN), CBC with differential
39
What is the only Mesalamine dosage form that has effects on the small intestine and colon?
Pentasa ER capsules
40
Mesalamine should be used with caution in patients with what?
renal or liver insufficiency
41
Which Aminosalycilate does not require caution in patients with renal/ liver insufficiency?
Olsalazine
42
What oral corticosteroids are used for IBD?
Prednisone Budesonide
43
What are contraindications to corticosteroid use?
Systemic fungal infections LIVE vaccines
44
What corticosteroids are used IV?
Hydrocortisone Methylprednisolone
45
What corticosteroids are used topically?
Hydrocortisone Budesonide
46
What is the only corticosteroid that can be used up to 3 months?
Budesonide
47
What must be done if Budesonide is stopped after being used for >2 weeks?
Taper to avoid withdrawal
48
Why can Budesonide be used for a longer period of time?
extensive first-pass metabolism; decreased systemic exposure
49
What agents require genotype/ phenotype testing prior to initiation to properly dose and determine enzyme (TPMT) activity responsible for drug metabolism?
Thiopurines (Mercaptopurine and Azathioprine)
50
What agents should be used with caution when taking thiopurines?
5-ASAs can inhibit TPMT, the enzyme responsible for thiopurine drug metabolism
51
What ADEs are seen with thiopurines?
Bone marrow suppression Anemia Thrombocytopenia Hepatotoxicity Renal toxicity Pancreatitis N/V/D rash
52
When is cyclosporine used?
Severe UC flares not responding to IV corticosteroids
53
What BBWs are seen with thiopurines?
chronic immunosuppression; increased risk of malignancy and hematologic toxicities
54
What BBWs are seen with Janus Kinase (JAK) inhibitors?
Serious bacterial, fungal, viral, and opportunistic infections Higher rate of all-cause mortality including sudden CV death Higher rate of MACE Increased risk of thrombosis (PE, DVT, arterial thrombosis) Increased risk of lymphomas/ other malignancies
55
What can be given with TNF inhibitors to decrease infusion reactions?
APAP diphenhydramine corticosteroid
