Understanding Loeffler’s Syndrome: Causes, Symptoms, and Association with Ascaris Lumbricoides

Which of the following is associated with LOEFFLER’S SYNDROME:A. Ascaris lumbricoidesB. Enterobius vermicularisC. Trichuris trichiuraD. Wuchereria bancrofti

LOEFFLER’S SYNDROME is associated with A

LOEFFLER’S SYNDROME is associated with A. Ascaris lumbricoides.

Loeffler’s syndrome, also known as eosinophilic lung disease, is a condition characterized by inflammation of the lungs caused by an immune response to certain parasites. In this condition, a parasite called Ascaris lumbricoides is primarily responsible for triggering the immune response.

Ascaris lumbricoides is a common intestinal parasite that infects humans who ingest its eggs through contaminated food or water. Once ingested, the eggs hatch in the intestine, and the larvae migrate through the bloodstream and reach the lungs. It is during this migration that the larvae trigger an immune response, leading to the development of Loeffler’s syndrome.

The immune response in Loeffler’s syndrome is characterized by the infiltration of eosinophils, a type of white blood cell, into the lung tissue. This accumulation of eosinophils causes inflammation and leads to symptoms such as coughing, shortness of breath, wheezing, and fever.

It is important to note that while Loeffler’s syndrome is primarily associated with Ascaris lumbricoides, it can also be caused by other parasitic infections, such as those caused by other helminths (worms) like Wuchereria bancrofti (which causes lymphatic filariasis) or other parasites from the Enterobius (pinworm) or Trichuris (whipworm) genera. However, these are less commonly associated with Loeffler’s syndrome compared to Ascaris lumbricoides.
