IBD; ulcerative colitis Flashcards
What is Ulcerative colitis
Mucosal inflammation in colon and rectum
Symptoms
Rotates between flare up and remission
1= bloody diarrhoea (can contain mucus or pus)
2) abdominal pain lower, urgent need to defecate
3) acute flare up - mouth ulcers sore skin, weight loss , fatigue, arthritis
Long term Complications
Colorectal cancer
Secondary osteoporosis (dietary change or long term steroid)
VTE
Toxic mega colon
C/I
Loperamide/ codeine I.e.
Anti motility or anti spasmodic Drug contraindicated risK of paralytic ileum= toxic megaColon
Treatment depends on location
Extensive colon oral
Left sided colitis (distal)= liquid enema
Proctosigmoiditis = Foam enema
Proctitis (rectum)= suppository
For proctosigmoid / proctitiss - foam and suppository easier retained than liquid
Treatment P/PS mild- mod uc
1st line = rectal aminosalicylate
2nd line= Rectal corticosteroid or oral prednisolone
Treatment LSC/extensive
1st = high dose oral aminosalicylate + rectal aminosalicylate or oral betametasone if necessary
Alt= oral pred only
Subacute moderate to severe UC
Give oral prednisolone
Alt= monoclonal antibody
Initial tx failure in Acute mild to mod UC - all extents
Give oral pred (if no improve with aminosalicylate after 4 weeks)
2nd line oral tacrolimus (if symptoms don’t improve 2-4 weeks)
Medical emergency severe acute UC
A= give if steroids +assess need surgery
Alternative - iv ciclosporin Or surgery
B = If symptoms worse/ don’t improve 72hrs
Give iv ciclosporin +iv steroid Or surgery
Alternative to ciclosporin = infliximab
Why aminosalicylates for maintenance tx over steroids
Steroids have too many s/e
Maintentance p/ ps
Rectal aminosalicylate +oral aminosalicylate (oral aminosalicylate can be used alone but less effective)
Maintenance tx of LSC/extensive
Low dose aminosalicylate oral (single daily dose over multiple dose, this has s/e)
If two or more flare ups requiring surgery in 12 months Requiring steroids, remission not treated ted by aminosalicylste ,or after severe flare (in extensive or LSC
Oral azathiprine or mercaptopurine
However, if in acute flare up monoclonal antibodies were effective this can be continued
