Symptoms of parasitic diseases

Symptoms caused by larval migration: Ascaris lumbricoides eggs migrate to the lung, causing bronchiolar epithelial cells to fall off and pulmonary hemorrhage, resulting in pulmonary Ascaris lumbricoides. The symptoms are cough, chest tightness, bloody sputum, increased blood eosinophils, and no obvious lung signs. X-ray chest film shows punctate, flake or flocculent shadows in the lung, and the lesions are easy to change or disappear soon, It is called Ascaris juvenile pneumonia or Ascaris eosinophilic pneumonia, namely loefler syndrome. Symptoms disappeared in 1-2 weeks. In severe infection, the larvae can invade the brain, liver, spleen, kidney, thyroid and eye, causing corresponding clinical manifestations, such as epilepsy, hepatomegaly, abdominal pain and so on.

Symptoms caused by adults: Adults parasitize the jejunum and feed on half digested food in the intestinal cavity. The clinical manifestations were anorexia, anorexia and pica; Often abdominal pain, located around the navel, like to knead, not severe; Some patients are irritable, easy to be frightened or depressed, and have molars; The heterologous protein can cause urticaria and other allergic symptoms. Severe infection can cause malnutrition and affect growth and development.

Complications: Ascaris lumbricoides has the habit of drilling holes. Under the stimulation of human discomfort (fever, gastrointestinal diseases, etc.), or a large amount of spicy food and improper dosage of anthelmintic drugs, Ascaris lumbricoides can drill into various pipes opening in the intestinal wall, which can not only cause biliary ascariasis and ascaris intestinal obstruction, but also block the trachea and bronchus, resulting in asphyxia and death, It may also cause inflammation by drilling into the appendix or pancreatic duct.
