2) Systemic steroid: Prednisone 40-60 mg +/- AZA
3) Biologic: Infliximab +/- AZA

Q

UC: fulminant

A

> 10 stools/day
CONTINUOUS blood
hgb < 8 (pt needs transfusion)
ELEVATED
- ESR/CRP/FP

24
Q

UC: fulminant treatment

A

Active
1) IV steroids x 3 days (hydrocortisone/methylprednisolone)
2) IV infliximab (UC only)
3) IV cyclosporine

Surgery - colectomy

Maintenance
- Steroid: AZA
- Biologic: same biologic +/- AZA
- Cyclosporine: AZA or vedolizumab

25
5-ASA drugs
Sulfasalazine - sulfa carrier Mesalamine Olsalazine Balsalazide - inert carrier
26
Mesalamine forms
Pentasa - wide GI coverage Rowasa and Canasa - Rectal Used more for ulcerative colitis (lower colonic)
27
Immunomodulator drugs
Maintain remission Azathioprine -workhorse 6-mercaptopurine Methotrexate - crohns only (IM/SQ =>PO) Cyclosporine - fulminant UC
28
Azathioprine (AZA)
prodrug m6p Takes 3 months to work Steroid sparing (use less steroid) Improve biologic efficacy (decrease ADA)
29
Azathioprine (AZA) monitoring
CBC Q 3 months LFT - hepatotoxicity Pancreatic enzymes - pancreatitis
30
Azathioprine (AZA) BBW
Lymphoma risk Increased risk w/ biologic therapy use
31
Corticosteroids
Induction therapy Predisone = PO Methylpred, HC = IV Budesonide = PO (CD maintenance) - Enterocort = CD; terminal ileum - Uceris = UC; colon
32
CD: enteric gram-negative/anaerobe abx
Metronidazole Ciprofloxacin 3rd gen cephalosporins
33
Infliximab
Remicade IV = infusion center
34
Adalimumab
Humira SQ, use at home, better QoL
35
Biologic drugs
Infliximab IV Adalimumab SQ Certolizumab Golimumab
36
Biologic drug BBW
Infections (TB, fungal, bacteria, viral, etc) PPD, chest X-ray, screen for HBV, HCV, HIV at baseline Malignancies - lymphoma
37
Integrin inhibitors
Natalizumab Vedolizumab
38
Natalizumab BBW
progressive multifocal leukoencephelopathy w/ reactivation of john cunningham virus REMS program
39
interleukin inhibitors
Ustekinumab (IL12, IL23) - stelara Risankizumab (IL23) - skyrizi
40
non- biologics
Tofacitinib PO (JAKi) Upadacitinib PO (JAKi) Ozanimod PO (S1P) Limited to TNFa failure
41
Jak inhibitor BBW
Cancer Cardiac (MACE) thrombosis infections death
42
Infusion-related reactions
IV products - Methylprednisolone, hydrocortisone - both - Infliximab - both - Cyclosporine - full UC
43
SQ better QoL
Adalimumab - Both Certolizumab - CD Golimumab - UC
44
Which 5ASA also used for CD, what kind?
Sulfasalazine for colonic involvement
45
Methotrexate and tacrolimus used in which IBD?
Crohns
46
What are metronidazole and Cipro for in IBD?
CD fissure/fistulas use with infliximab and surgery
47
How long for budesonide to work?
2-4 weeks
48
How long is budesonide therapy?
PO, 8 weeks
49
Jak stat inhibitors are used in which IBD?
Ulcerative colitis
50
Vedolizumab: what class and indication?
Integrin inhibitor, for ulcerative colitis maintenance after induction with cyclosporine
51
When do we not use AZA for active UC?
Active fulminant - use IV steroids x3 days, IV infliximab, IV cyclosporine or surgery
52
When do we not use AZA for active CD?
Mild-moderate cases Severe-fulminant cases - IV steroids, IV infliximab or surgery
53
5ASA MOA
acts topically to reduce inflammation (PG) locally Decreases PG, LT, lipoxygenase, NFkB
54
Pentsa (mesalamine)
