Overview
Ascariasis is often asymptomatic.[1] Complications may arise when adult worms move to certain organs such as the bile duct, pancreas, or appendix..[1] A high worm burden can also result in complications such as intestinal obstruction.[2]
Natural History
The majority of people infected with Ascaris are asymptomatic although greater than 15% can experience some type of morbidity.[1]
Complications
Complications of ascariasis include the following:[3][2][4]
- Biliary duct disease
- Hepatic abscess
- Intestinal obstruction associated with perforation, volvulus, and intussusception
- Peritonitis
- Pancreatitis
- Acute appendicitis
- Malabsorption and growth impairment from chronic infection with Ascaris lumbricoides
- Interstitial nephritis and acute renal failure (rare)
- Acute eosinophilic pneumonia resulting in respiratory distress (rare)
Prognosis
Most infection are asymptomatic but mortality can be as high as 60,000 per year.[1]
