The anaphylactic shock induced by echinococcosis can be cytotoxic and is mainly the result of synergistic effects of type 1 immediate hypersensitivity and endotoxic shock [4,6–9]. Large amounts of vasoactive substances are found in CE and could induce vasomotor dysfunction and result in peripheral circulatory failure.
Which liver infections can be complicated with anaphylactic shock?
Cystic hydatid disease usually affects the liver (50–70%) and less frequently the lung, the spleen, the kidney, the bones, and the brain [1-3]. Liver hydatidosis can cause dissemination or anaphylaxis after a cyst ruptures into the peritoneum or biliary tract.
How is hydatid cyst caused?
Cystic echinocccosis (CE), also known as hydatid disease, is caused by infection with the larval stage of Echinococcus granulosus, a ~2–7 millimeter long tapeworm found in dogs (definitive host) and sheep, cattle, goats, and pigs (intermediate hosts).
What is hydatid cyst disease?
Hydatid disease (also known as hydatidosis or echinococcosis) is a potentially serious, sometimes fatal, condition caused by cysts containing the larval stages of the Echinococcus granulosus (E. granulosus) tapeworm (Dog Tapeworm).
Where do hydatid cysts form in humans?
Human infection with E. granulosus leads to the development of one or more hydatid cysts located most often in the liver and lungs, and less frequently in the bones, kidneys, spleen, muscles and central nervous system.
Can hydatid cyst cause jaundice?
Background/aim: Compression of the common bile duct by a hydatid cyst located at the head of the pancreas is one of the quite rare causes of obstructive jaundice in childhood.
How is Echinococcus tapeworm transmitted to humans?
The most common mode of transmission to humans is by the accidental consumption of soil, water, or food that has been contaminated by the fecal matter of an infected dog. Echinococcus eggs that have been deposited in soil can stay viable for up to a year.
What complication can occur in hydatid cyst disease?
Complications of hydatid cyst of the liver. Echinococcal cysts of the liver can cause complications in about 40% of cases. The most common complications in order of frequency are infection, rupture to the biliary tree; rupture to the peritoneal cavity; rupture to the pleural cavity.
