The following are the most important diseases or complications that can be caused by amoebic dysentery (intestinal form/affecting the intestine):
Endocrine, nutritional, and metabolic diseases (E00-E90).
- Severe fluid and electrolyte losses to circulatory failure and shock.
Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).
- Fulminant course (sudden, rapid, and severe development) with toxic megacolon – massive dilatation (enlargement) or enlargement of the colon in the setting of inflammation; very rare.
- Colon perforation with peritonitis – rupture of the colon wall (intestinal perforation) with peritonitis.
The following are the main diseases or complications that can be caused by an amoebic liver abscess (extraintestinal form/outside the intestine) with:
Eyes and eye appendages (H00-H59).
- Keratitis (corneal inflammation) – Caveat. Contact lens wearers (keep contact lenses always in fresh storage solution).
Respiratory system (J00-J99)
- Rupture (breakthrough) into the pleural space (narrow space in the chest cavity between the inner top of the rib cage and the pleura).
Cardiovascular system (I00-I99)
- Rupture into the pericardium (heart sac) – rare.
Mouth, esophagus (food pipe), stomach, and intestines (K00-K67; K90-K93).
- Rupture into the abdominal cavity
Psyche – nervous system (F00-F99; G00-G99)
- Encephalitis (inflammation of the brain) – granulomatous amoebic encephalitis (GAE).
- Brain abscess (collection of pus in the brain) – rare.
- Primary amebic meningoencephalitis (PAM; combined inflammation of the brain (encephalitis) and meninges (meningitis)) – caused by Naegleria fowleri, a common amebic species in the United States; clinical symptoms: high fever, nausea (nausea), frequent vomiting, cephalgia (headache), and neck stiffness (meningismus) typical of meningitis.
