Overview

Clinical manifestations may range from an asymptomatic course to a severe/fatal presentation. Common symptoms include acute-onset, foul-smelling watery diarrhea, crampy diffuse or lower abdominal pain, low-grade fever, malaise, anorexia, nausea, and weight loss. Alarming symptoms that may be suggestive of colonic complications of C. difficile infection include worsening abdominal pain and diarrhea, high-grade fever, dry mucus membranes, and peripheral edema.

History and Symptoms

Clinical manifestations may range from an asymptomatic course to a severe/fatal presentation.

Common Symptoms

Acute-onset, foul-smelling watery diarrhea with or without pus. Diarrhea may occasionally be bloody. Diarrhea may be relieved by passage of stools.
Crampy, diffuse/lower abdominal pain
Low-grade fever
Malaise
Anorexia
Nausea
Weight loss

Alarming Symptoms Suggestive of Colonic Complications

Patients with C. difficile infection may have a complicated clinical course due to either colonic or extracolonic complications. Common colonic complications include pseudomembranous colitis and toxic megacolon. The following list of symptoms demonstrates the alarming symptoms that may be suggestive of colonic complications of C. difficile infection:

Worsening diffuse/lower abdominal pain
Foul smelling, watery diarrhea with or without pus or blood. Diarrhea may be relieved by passage of stools.
High-grade fever
Dry mouth and mucus membranes due to dehydration
Peripheral edema due to hypoalbuminemia
Delirium
Coma

 == Overview ==
-Often clinicians begin treatment before results have come back based on clinical presentation to prevent complications. Knowledge of the local epidemiology of intestinal flora of a particular institution can guide therapy.
+Clinical manifestations may range from an asymptomatic course to a severe/fatal presentation. Common symptoms include acute-onset, foul-smelling watery [[diarrhea]], crampy diffuse or lower [[abdominal pain]], low-grade [[fever]], [[malaise]], [[anorexia]], [[nausea]], and [[weight loss]]. Alarming symptoms that may be suggestive of colonic complications of ''C. difficile'' infection include worsening [[abdominal pain]] and [[diarrhea]], [[high-grade fever]], [[dry mucus membranes]], and [[peripheral edema]].

 ==History and Symptoms==
-Clinical manifestations can be quite variable.  Some patients are asymptomatic, and others can present critically ill with [[toxic megacolon]].
+Clinical manifestations may range from an asymptomatic course to a severe/fatal presentation.
-* Up to 2/3 of infected hospitalized patients are asymptomatic, but shed organisms and contaminate their environment.  These patients are called ''C. Diff'' fecal excretors.  These patients can be treated with [[vancomycin]] or metronidazole, but the bug is often not eradicated in these patients.
-* The reason for the variability is not clear and is not accounted for by strain differences.  Host factors are probably important, such as the presence of antitoxin antibodies and colonic toxin receptors.
-* Risk factors for severe [[colitis]] include malignancy, [[Chronic Obstructive Pulmonary Disease]] (COPD), [[immunosuppression]], [[renal failure]], exposure to anti-peristaltic meds and [[clindamycin]].
-* Onset is usually during or shortly after a course of antibiotics.  Cases rarely occur even a month after a course of antibiotics.  Rarely patients have no recent history of antibiotics.
-'''Antibiotic-associated diarrhea with ''C. diff'' infection, but without colitis'''
+=== Common Symptoms ===
-* Acute, foul-smelling watery [[diarrhea]], with a mean of 3-4 stools a day.
+* Acute-onset, foul-smelling watery [[diarrhea]] with or without pus. Diarrhea may occasionally be [[Bloody diarrhea|bloody]]. Diarrhea may be relieved by passage of [[stools]].
-* Lower [[abdominal pain]], sometimes crampy
+* Crampy, diffuse/lower [[abdominal pain]]
 * Low-grade [[fever]]
-'''Antibiotic-associated diarrhea with C. diff infection with colitis''', but without pseudomembrane development
-In addition to profuse, watery diarrhea of 5-15 bowel movements daily, the patients suffer from:
-* [[Fever]]
 * [[Malaise]]
 * [[Anorexia]]
-* Lower quadrant [[abdominal pain]] and cramps, relieved by the passage of diarrhea.
 * [[Nausea]]
-* [[Dehydration]]
+* [[Weight loss]]
-* [[Leucocytosis]]
-* Fecal [[leucocytes]] present in >50%.  Occult [[bleeding]] not uncommon.
-* [[Sigmoidoscopy]] shows a nonspecific diffuse or patchy erthrematous [[colitis]] without pseudomembranes.
-'''Antibiotic-associated diarrhea with ''C. diff'' infection with colitis and pseudomembrane development'''
+=== Alarming Symptoms Suggestive of Colonic Complications ===
-Patients tend to have the prominent signs as symptoms described above.
+Patients with ''C. difficile'' infection may have a complicated clinical course due to either colonic or extracolonic complications. Common colonic complications include pseudomembranous colitis and toxic megacolon. The following list of symptoms demonstrates the alarming symptoms that may be suggestive of colonic complications of ''C. difficile'' infection:
-* Rarely patients will develop indolent, subacute [[pseudomembranous colitis]] with a protein-losing state due to the diffuse [[pancolitis]].  Patients may have severe [[hypoalbuminemia]], [[ascites]], peripheral [[edema]], and their only signs/symptoms may be low-grade [[fever]], [[anorexia]] and [[abdominal discomfort]].
+* Worsening diffuse/lower [[abdominal pain]]
-* [[Sigmoidoscopy]] shows pseudomembranes; raised yellow or off-white plaques ranging up to 1 cm in diameter scattered over the colorectal mucosa.
+* Foul smelling, [[watery diarrhea]] with or without pus or blood. Diarrhea may be relieved by passage of [[stools]].
-*:* Occasionally pseudomembranes will be located in the proximal colon.
+* High-grade [[fever]]
+* Dry mouth and mucus membranes due to [[dehydration]]
-'''Fulminant colitis'''<br>
+* [[Peripheral edema]] due to [[hypoalbuminemia]]
-Fulminant [[colitis]] is an uncommon complication that occurs in 2-3% of patients with ''C. Diff'', and can results in perforation, prolonged [[ileus]], [[megacolon]], and [[death]].
+* Delirium
-Patients may present with:
+* Coma
-* Severe [[abdominal pain]] and distension
-* Severe [[diarrhea]]; diarrhea may be absent in patients with ileus
-* [[Fever]], [[chills]]
-* [[Lethargy]]
-* [[Tachycardia]]
-* [[Leucocytosis]], up to 40,000 mm3
-* [[Metabolic acidosis]]
-'''Toxic megcolon''' is an enlarged, dilated colon >7cm associated severe systemic toxicity.
-* Small intestinal dilation may also occur
-* Air-fluid levels may be present
-* Submucosal [[edema]] may result in thumb-printing
