Destroying foreign substances. Eosinophils can consume foreign substances — particularly substances related to infection with a parasite — that have been "flagged" for destruction by other components of your immune system.
Regulating inflammation. Eosinophils help promote inflammation, which plays a beneficial role in isolating and controlling a disease site. But, sometimes inflammation may be greater than is necessary, which can lead to troublesome symptoms or even tissue damage. For example, eosinophils play a key role in the symptoms of asthma and allergies, such as hay fever. Other immune system disorders also can contribute to ongoing (chronic) inflammation.
Eosinophilia occurs when either a large number of eosinophils are recruited to a specific site in your body or bone marrow produces too many eosinophils. This can be caused by a variety of conditions, diseases and factors, including:
Parasitic and fungal diseases
Allergies, including to medications or food
Specific diseases and conditions that can result in blood or tissue eosinophilia include:
Parasitic diseases and allergic reactions to medication are among the more common causes of eosinophilia. Hypereosinophilic syndrome tends to have an unknown cause or results from certain types of cancer, such as bone marrow or lymph node cancer.
Vitamin B12 does not accumulate to toxic levels. Consuming large quantities does not cause side effects or high levels in your system, whether you get it through food or from taking high-dose supplements.
High vitamin B12 in the bloodstream is associated with serious diseases. Medical conditions that can increase levels of vitamin B12 include liver disease, kidney failure and a group of blood cancers known as myeloproliferative disorders, which includes myelocytic leukemia and a condition that causes an overgrowth of red blood cells called polycythemia vera.
Hypereosinophilic syndrome, a medical condition marked by too many white blood cells, also can cause high vitamin B12.
Your PM to me:
"Total bili 2.1 ALP. 273 AST. 470 ALT. 1383. Double checked Absolute monos. 979 Absolute eos. 864 B12. 1224 Of course they are not listening to me and my symptoms just freaking out over liver enzymes, and I have not disclosed how much Albenza and Ivermectin I have taken. Never took Alb more than a week without rest. Can not figure what elevated Eos and elevated B12 indicate. Thought maybe you could help?? Start d out treating supposed oinworms, but then looked very much like D. Caninum and took Praziquantel with much relief. Still seeing minute amount of dessicated pieces in underwear. No other sx. Any input appreciated. CT scan of liver and Gb scheduled. Did pass huge gallstone, found in stool specimen I sent to lab, but of course all that including O&P came back neg. only other positive lab was 6-10 squ,ous epithelial cella in urine. Scared here. Do you think Liver enzymes will go back down?"
