CHIEF COMPLAINT(S)
“Persistent diarrhea and pruned skin”
![Page 4: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/4.jpg)

HISTORY OF PRESENTING ILLNESS – 1/2 Ms. J is a pleasant 77 year-old female who presents with persistent diarrhea for 3 weeks, at 4-5 times/day. It is of watery consistency, brown color, foul smell, with traces of blood – though the patient reports of internal hemorrhoids as a possible reason – no mucus, and of undigested food.
The patient reports increased urge to void after consuming a meal and a coinciding BM with micturition, in addition, she reports of a progressively worsening frequency. She does not report of any active pain, but of slight lower abdominal discomfort for 15-20mins after a BM.

HISTORY OF PRESENTING ILLNESS – 2/2 Ms. J reports of having a previous episode (2010) with
similar symptoms which was diagnosed as pseudomembranous colitis; she reports of no nausea, vomiting, sick contact or recent travel. Ms. J also reports of acute stress due to a sickness in the family.
She was prescribed Flagyl (metronidazole) for 10 days, for which she is on her 10th day. She was advised by her PCP to consume bananas and cheese to help with the diarrhea but had no improvement.
Ms. J reports having a dental procedure one month ago in which amoxicillin (4 tabs) was used.
She also stopped taking her monthly Simponi (Golimumab) injections for her RA because she believed it was the cause.

DIFFERENTIAL DIAGNOSIS – 1/3 Pseudomembranous colitis (C. difficile) 2o to
antibiotic use Gram-positive obligate rod. Toxins bind brush border, destroy
cytoskeletal structure of enterocytes. 2o to clindamycin/ampicillin. Watery diarrhea, abdominal pain, anorexia, malaise, fever.
Irritable Bowel Syndrome Recurrent abdominal pain with 2 or more: pain improves with
defecation, changing stool frequency, changing stool appearance. Middle-aged women, chronic, may have diarrhea/constipation.
Inflammatory Bowel Disease Crohn’s disease: rectal sparing, transmural, “string sign” on Ba
swallow, Th1 mediated. Ulcerative colitis: continuous until rectal, bloody diarrhea, “lead
pipe” appearance on imagining, Th2 mediated.

20
DIFFERENTIAL DIAGNOSIS – 2/3 Infections (watery diarrhea):
Vibrio cholera: cAMP, Gs
C. perfringens: gas gangrene, lecithinase α toxin Protozoa: Giardia (foul-smelling, campers/hikers, fatty diarrhea,
trophozoites/cysts in stool), Cryptosporidium (AIDS pts) Strongyloids stercoralis: larvae in soil penetrate through skin Enterotoxigenic E.coli: traveler’s diarrhea, ST & LT toxins Viruses: Rotavirus (dsRNA), norovirus (ssRNA)
Endocrine disorders: hyperthyroidism, diabetic gastroparesis, niacin deficiency
![Page 21: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/21.jpg)
21
DIFFERENTIAL DIAGNOSIS – 3/3 Malabsorption syndromes:
Whipple’s: Tropheryma whipplei (gram+), PAS+, foamy macrophages, [CVS, arthralgias, neuro.] symptoms, older men.
Celiac spruce (autoantibodies to gluten): distal duodemum, proximal jejunum, loss of villi.
Disaccharidase deficiency (lactase): normal villi, lactase located at tips of villi, can occur following injury (e.g., viral diarrhea).
Pancreatic insufficiency: cystic fibrosis, cancer, chronic pancreatitis, fat in stool.
![Page 22: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/22.jpg)

PATHOPHYSIOLOGY
Bacterial flora of colon disturbed C. difficile colonize toxins released mucosal inflammation and damage
Antibiotics: ampicillin/amoxicillin, clindamycin, cephalosporins (esp. 2nd & 3rd gen.), and fluoroquinolones
ToxA (enterotoxin) or ToxB (cytotoxin) bind cell surface receptor endocytosis of toxin-receptor complex low endosome pH leads to pore-formation glucosyltransferase (GTF) & protease translocation into cytosol
cysteine protease domain activated by inositol hexakisphosphate (InsP6) cofactor, cleaves toxin, releases GTF domain into cytosol RHO-family gets glycosylated RHO GTPase inactivated
RHO proteins: assist in actin polymerization, cytoskeletal architecture, and cell movement Inflammation & damage
![Page 23: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/23.jpg)
FOUR DOMAINS OF TOXA / TOXB (C. DIFFICILE)1. Domain B (green): carboxy-
terminal 'binding' domain binds to a cell surface receptor
2. Domain D (yellow): the 'delivery‘ domain is involved in translocation of the toxin into the cytosol
3. Domain C (blue): cysteine protease 'cutting' domain
4. Domain A (red): biologically active glucosyltransferase domain

![Page 24: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/24.jpg)
24
FINDINGS TO SUPPORT DIAGNOSIS – 1/3 Leukocytosis (15,000 μL)
Acute kidney injury: Elevated WBC and Creatinine (1.5x pre-morbid level)
Electrolyte imbalances, dehydration, hypoalbuminemia, anasarca
Stool Examination & Stool Assay’s: 1. Culture (gold-standard)2. Glutamate dehydrogenase (GDH) enzyme immunoassay
(EIA)3. Real-time PCR gene toxin4. Cell cytotoxic assay5. EIA for ToxA and ToxB6. Latex agglutination to detect GDH
Guidelines suggest: # 2 (detection) & # 4 (confirmation)
![Page 25: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/25.jpg)
25
FINDINGS TO SUPPORT DIAGNOSIS – 2/3 Endoscopy: raised, yellowish white, 2- to 10-mm
plaques overlying an erythematous, edematous mucosa
Histologic: biopsy reveals an inflammatory exudate composed of mucinous debris, fibrin, necrotic epithelial cells and polymorphonuclear cells
![Page 26: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/26.jpg)
26
FINDINGS TO SUPPORT DIAGNOSIS – 3/3 Computed Tomography Scanning: Marked colonic
wall thickening. Ascites, irregularity of bowel wall, pericolonic stranding, megacolon.
![Page 27: Clinical case seminar - Gagandeep Singh Anand - LINKEDIN](https://reader031.fdocuments.us/reader031/viewer/2022032118/55ccc556bb61ebaf4b8b481b/html5/thumbnails/27.jpg)
27
TREATMENT OPTIONS – 1/2
Pharmacological: Mild-Moderate: metronidazole / vancomycin PO (10-14 d) Severe-complicated: empirical vancomycin PO (10-14 d) Relapse from mild-moderate:
1st relapse: metronidazole (forms free radical metabolites in bacteria) 2nd relapse: vancomycin (binds D-ala D-ala of cell wall precursors)
Probiotics may be useful for prevention
Fecal Microbiota Transplanation: transfer healthy donor stool to C. difficile infected patient reconstituting normal colonic flora Very promising results!
Surgical: fulminant colitis & toxic megacolon require surgical intervention
