Why Is Infection With Tematode Increases Leukocytosis

Parasitical Worms.com Doctor: I went for a general health examination according to the company, the result of an elevated blood eosinophilia, the doctor said I might have a parasitic worm parasite in my blood and advised me Go to a specialized clinic about helminths for testing. So the doctor let me ask why the infection with intestinal helminths increased eosinophilus and after the treatment of eosinophilic worms increased, sir
Hello, please answer you as follows.
In the direction of diagnosis and follow-up of disease change when an increase in eosinophils is detected in a patient, it is necessary to monitor several times to make a Lavier chart. If combined with epidemiological and clinical factors, it is possible to target one or two helminthic parasites, thereby determining the type and method of collection of specimens and the appropriate testing method (direct and / or indirectly) to proceed to the definitive diagnosis

. After successful specific treatment, helminth parasites have been destroyed and eosinophils will return to normal.
For example, a patient is infected with Ascaris lumbricoides roundworm
- week 0 - 2: worms in larval stage
- week 2 - 4: young worms
- Weeks 4 - 8: worms mature but do not lay eggs
- week 8 onwards: the adult worms begin to lay eggs
With the old concept, when Loeffler syndrome was discovered (weeks 1 - 2), people did not have specific treatment until they found fecal worm eggs (from week 8).
We now know the drug has no effect on the larvae, but it works for young and adult worms So, just follow the Lavier chart, when you begin to step through the stage of eosinophilia reduction (from the beginning of the 3rd week), we can give wormworm drops even though at that time, we tested for eggs in stool negative.
In the case of Fasciola hepatica, when the flukes are still in the parenchyma of the liver parenchyma, the flukes, such as emetin, are high in concentration and in direct contact with immature flukes, thus eliminating the fluke.



.
But when the worms enter the bile ducts and grow up, the medicine no longer works! Therefore, when looking at the diagram of Lavier% eosinophils in the high stage, we know that the fluke is still traveling, meaning that it can be treated. On the contrary, if eosinophil%% is in the reduced stage, we understand that the flukes have entered the bile ducts, the ability to cure is no longer available.
In Vietnamese% eosinophils are only called high when Eos is greater than 7%. The percentage of Vietnamese infected with helminths is quite high; therefore, if the wrong people with the helminths are selected (ie during the period of reduction or asymptosis, the eosinophilia is higher than normal), the count will be ordered. If carefully selected people are not infected with helminths, the% of eosinophils in Vietnam is still less than 3%
Why is infected with parasitic worms increase the eosinophilia
Because the toxins of the parasite have a structure similar to the immune structure of the body leading to increased eosinophils Besides, there is an increase in histamine, which leads to an increase in eosinophils to swallow cells and neutralize the harmful effects of histamine.
When infected with eosinophilic helminths have the effect: Clean up antigen-antibody complexes, neutralize histamine by histamine enzymes
Your case should go to the parasite specialty clinic for blood tests to find the parasite that causes the disease and some other causes of eosinophilia, such as some external allergic factors.
Good health to you.
