(40 cards)
Which part of the colon does Ulcerative collitis affect
Rectum (proctits 50%)
or extend and invlve part of the colon (left-sided colitis 30%)
or the entire colon (pancolitis 20%)
Never spreads proximal to the illoceacal valve.
Causes of UC
Idiopathic
genetic
Which gene is associated with UC
HLADR103
Risk factors of UC
most present aged 15-30
More in non/ex smokers
Appendectomy protects
Risk factors for Crohn’s
More common in smokers
Presentation of UC
Episodic or chronic diarrohoea (+- blood or mucus)
Crampy abdominal discomfort
urgency/tenesmus - rectal UC
systemic symptoms in attacks: fever, malaise, anorexia, weight loss
higher stool frequency compared to Crohns
A 35 year old male presents with weight loss, diarrohoea, and abdominal pain. On examination he has apthous ulcers in the mouth and a palpable mass in the right illiac fossa.
Crohn’s disease
Extraintestinal signs of IBD in the mouth
Apthous ulcers in the mouth
Extraintestinal signs of IBDin the eyes
conjuctivitis
Iritis
Episcliritis
Extraintestinal signs of IBD in the liver
Abscess, fatty change, hepatitis, sclerosing cholangitis
vascular Extraintestinal signs of IBD
Mesenteric, portal or deep vein thrombosis
Extraintestinal signs of IBD in the skin
Erythema nodosum, pyoderma gangrenosum
Extraintestinal signs of IBD in the boins/joints
Metabolic bone disease, sacroiliitis
Mild UC characteristics
<4 motions/day
small rectal bleeding
HR <70
Moderate UC characteristics
4-6 motions/day
medium rectal bleeding
HR 70-90
Severe UC characteristics
> 6 motions/day
severe rectal bleeding
HR >90
Symptoms of crohn’s disease
Diarrhoea/urgency “I get up at 4am and go 5-6 times in the next 45 mins”
Abdominal pain, weight loss, fever, malaise, anorexia.
“I can be fine one minute and deathly the other”
Signs of Crohn’s
Apthous ulcers
Abdominal tenderness/mass
Fistulae
perianal abscess
skin tags
Anal strictures
Investigations for inflammatory bowel disease
FBC - Anaemia
ESR
CRP
Faecal Calprotectin
Stool sample
Blood cultures
Sigmoidoscopy
Endoscopy/ Colonoscopy for biopsy
Radiology
When is ESR elevated
In exacebrations or because of abscess in IBD
What can we benefit from CRP
Helpful in monitoring Crohn’s disease activity
Why would you want a stool sample in IBD?
Help to exclude superimposed infections in exacebrations
What is sigmoidoscopy
Looks at rectum and sigmoid colon.
What can sigmoidoscopy show in UC
Loss of vascular pattern
granularity
Friability
Ulceration
