| Question | Answer |
| IBD common sx | Diarrhea (often bloody); Fatigue (poss rel to anemia, not nec); wt loss; anorexia; N/V; crampy abdominal pain (d/t obstructive sx?) |
| Features of CD | Any part of GI tract (most commonly terminal ileum); skip lesions; transmural |
| Features of UC | Limited to colon; starts in rectum; usually continuous; superficial; resulting in erosions, friability, bleeding |
| Specific clinical features of UC | Proctitis: tenesmus; bloody diarrhea more common; high risk of CRC |
| Specific clinical features of CD | fistula: abscesses; more common at anus; strictures of the intestine; CRC risk increased if > 1/3 colon involved; smoking & CD: bad |
| Extra intestinal manifestations of IBD: | may involve any area; usu eye, skin, liver, and joints (arthralgias, AS) |
| EIM: arthralgia Type 1: | self limited, short lived, affecting 6 or fewer joints. Associated with disease flares |
| EIM: arthralgia Type 2: | multiple joints, can be migratory, can be more chronic; NOT associated with disease flares. |
| Primary sclerosing cholangitis (PSC) | UC>CD; stricture of biliary ducts; Dx high alk phos; LFT, anti-mito Ab; ERCP/MRCP; risk for CRC; refer to hepatologist |
| Raised tender red-purplish nodules, on extensor surfaces of extremities, are called ____ and can be a sign of: | erythema nodosum; sx of Crohn dz. May require steroids |
| Pyoderma gangrenosum | wide spectrum of necrotic inflam; IBD tx, topical tx, or poss colectomy; DO NOT BX |
| IBD eye complications | episcleritis; uveitis: refer to Ophtho (blindness risk) |
| IBD: DDx includes: | infxs diarrhea; ischemia (elderly, PVD, thrombosis); meds (PCN, NSAID, CellCept); diverticular dz; perianal fistula |
| IBD dx/ eval: | Combo of endoscopy, histology, radiography, labs & clinical data; Colonoscopy with ileal intubation & bx (should see chronic colitis/enteritis); Small bowel follow-through, enteroclysis (+/- CT), MR enterography |
| IBD labs | often anemic (Fe def & chronic dz), leukocytosis, elevated CRP (CD); DO NOT ORDER serologies (ASCA, Cbir, OmpC & Crohns; p-ANCA & UC) |
| Genl principles of tx of IBD | Tx affected area (enema/supp: mild-mod proctitis; budesonide: ileal CD); use as little steroid as poss; not everyone needs tx or responds to same tx |
| Defn Mild UC: | ≤5 BM/day; no sx systemic toxicity; normal ESR |
| Defn Moderate UC: | >5 BM/day and <10lb wt loss; no sx systemic toxicity |
| IBD tx options | 5-ASA; corticosteroids; 6MP/AZA; anti-TNF Ab |
| 6MP/AZA MOA: | impair T cell fn; slow onset of action; AE pancreatitis, liver tox, cytopenia; |
| IBD colon ca risk/surveillance | CD/UC colitis >1/3 colon: colonoscopies starting 8 yrs from sx onset; q1-3 years; if comorbid PSC: immed start annual colonoscopy; FH also inc CRC risk |
| Dysplasia, cancer, or toxic colitis may: | necessitate colectomy. |
| Fibrotic strictures, obstruction, fistulae may: | necessitate segmental resection in CD (try to avoid surg if poss in CD) |
| IBD: Worrisome signs | frequent UTIs/pneumaturia (fistula to bladder); High fever/abd mass (abscess, liver abscess); severe abd pain (perf); N/V (obstruction); severe rectal pain (perirectal abscess) |
| Managing IBD flares | Similar to previous flares? Worrisome features; R/O infxn; labs (WBC, H/H); 5ASA (UC) or budesonide (ileal CD) |
| Granulomas on bx are highly suggestive of: | CD |
| CT scan for CD may show: | thickened, matted bowel loops, intra-abdominal abscess |
| Defn Severe UC: | Hourly BMs; toxic appearance, fever, tachy, Hct <25; 10-20lb wt loss |
| Test of choice for UC | sigmoidoscopy |
| Contraindicated in eval of acute UC: | Barium enema: may -> toxic megacolon |
| UC treatment | Distal: topical mesalamine; systemic steroids if tx failure. Acute dz above sigmoid: PO sulfasalazine & mesalamine |
| UC tx if intractable: | C-steroid enema trial; cyclosporine IV 4mg/kg/day; inflixamab |
| IBD and smoking | smoking decreases UC sxs; increases Crohn dz sxs |
| Crohn Dz findings | fistula: abscesses; more common at anus; strictures of the intestine; CRC risk increased if >1/3 colon involved; macro anemia |
| Pyoderma gangrenosum = | wide spectrum of necrotic inflam; IBD tx, topical tx, or poss colectomy; DO NOT Bx |
| IBD eye complications | episcleritis; uveitis: refer to Ophtho (blindness risk) |
| IBD colon ca risk/surveillance | CD/UC colitis >1/3 colon: colonoscopies starting 8 yrs from sx onset; q1-3 years; if comorbid PSC: immed start annual colonoscopy; FH also inc CRC risk |
| Pseudopolyps in CD: | Chronic damage & ulceration can lead to excess granulation tissues that protrudes into the intestinal lumen |
| Koilonychia = | spoon nails, may be sx of iron deficiency |
