Overview

Shigellosis must be differentiated from other diseases that cause fever, bloody diarrhea, dehydration, tachycardia and low blood pressure, such as Enterohemorrhagic E.coli (EHEC) infection, Ebola, Typhoid fever, Malaria, and Lassa fever.

Differentiating Shigellosis from other Diseases

The table below lists the underlying bacterial pathogens known to cause acute diarrhea:^[1]^[2]

Pathogen	Transmission	Clinical Manifestations
Pathogen	Transmission	Fever	Nausea/Vomiting	Abdominal Pain	Bloody Stool
Salmonella	Foodborne transmission, community-acquired	++	+	++	+
Shigella	Community-acquired, person-to-person	++	++	++	+
Campylobacter	Community-acquired, ingestion of undercooked poultry	++	+	++	+
Escherichia coli	Foodborne transmission, ingestion of undercooked hamburger meat	-	+	++	+ (EHEC or EIEC), - (ETEC, EAEC, EPEC)
Clostridium difficile	Nosocomial spread, antibiotic use	+	±	+	+
Yersinia	Community-acquired, foodborne transmission	++	+	++	+
Entamoeba histolytica	Travel to or emigration from tropical regions	+	±	+	±
Aeromonas	Ingestion of contaminated water	++	+	++	+
Plesiomonas	Ingestion of contaminated water or undercooked shellfish, travel to tropical regions	±	++	+	+

Shigellosis must be differentiated from other causes of watery chronic diarrhea^[3]^[4]^[5]^[6]

Cause			Osmotic gap		History	Physical exam	Gold standard	Treatment
Cause			< 50 mOsm per kg	> 50 mOsm per kg*	History	Physical exam	Gold standard	Treatment
Watery	Secretory	Crohns	+	-	Abdominal pain followed by diarrhea	Abdominal tenderness when palpated in severe disease Blood seen on rectal exam Fever Tachycardia Hypotension	Colonoscopy with biopsy	Topical mucosamine and corticosteroids are preferred Mesalamine and sulfasalazine are used for remission
		Hyperthyroidism	+	-	Excessive sweating Heat intolerance Increased bowel movements	Lump in the neck Proptosis Tremors Increased DTR	TSH with T3 and T4	Carbimazole and methimazole Beta blockers like propylthiouracil Iodine-131
		VIPoma	+	-	Watery diarrhea Dehydration (thirst, dry skin, dry mouth, tiredness, headaches, and dizziness) Lethargy, muscle weakness Nausea, vomiting Crampy abdominal pain Weight loss Flushing	Tachycardia Rash Facial flushing Abdominal distention Abdominal tenderness in the right upper abdominal quadrant	Elevated VIP levels Followed by imaging	Sandostatin or chemotherapy for malignant tumors Surgical removal of the tumor
	Osmotic	Lactose intolerance	-	+	Abdominal pain Bloating Diarrhea Flatulence	Abdominal tenderness	Intestinal biopsy	Avoidance of dietary lactose Substitution to maintain nutrient intake Regulation of calcium intake Use of enzyme lactase
	Osmotic	Celiac disease	-	+	May be asymptomatic Vague abdominal pain Diarrhea Weight loss Malabsorption / steatorrhea Bloatedness	Abdominal pain and cramping Abdominal distention Tetany Mouth ulcers Dermatitis herpetiformis Signs of the fat-soluble vitamins A, D, E, and K deficiency	IgA tissue transglutaminase Ab	Gluten-free diet
	Functional	Irritable bowel syndrome	-	-	Abdominal pain or discomfort recurring at least 3 days per month in the past 3 months and associated with 2 or more of the following: Improves with defecation Onset associated with change in frequency of stool Onset associated with change in appearance of stool 25% of bowel movements are loose stools History of straining is also common	Abdominal tenderness Hard stool in the rectal vault	Clinical diagnosis ROME III criteria Pharmacologic studies based criteria	High dietary fiber Osmotic laxatives such as polyethylene glycol, sorbitol, and lactulose Antispasmodic drugs (e.g. anticholinergics such as hyoscyamine or dicyclomine)
