Hi All,
Read the article by Perez-Lopez & Vieira-Batista in 2017, vol 20, No 4 issue of Climacteric.
I won't link it because they will delete the post and some of you may find this helpful.
They note that although bacterial/viral theory once was suspected, they do not find support for it.
These authors say we should not use clob more than 240 days a year. They also say biopsies do not necessarily lead to diagnosis.
Also, they discussed white blood cells. When the neutrophils are too high, in comparison to the lymphocytes, then one will have inflammatory T-cells and cytokines that both inflame tissues. The ratio of neutrophils to lymphocytes should be between .78 to 3.53. If you have a recent blood test where you have a WHITE CELL DIFFERNTIAL count, get it out and check it. Find the neutrophil and lymphocyte results and divide the neutrophil number by the lymphocyte number, one should get a result between .78 and 3.53. The neutrophils will probably be 1.8 or 2.4 or something like that and the lymphocytes around 2.0 to 4.0.
Ok, so I dug out my last Dec '18 blood tests and see that my ratio is too low at .72!
The inflammation is usually in response to antigens: bacteria, fungi, viruses, etc... which we know. One interesting anecdotal report was that certain drugs, carbamapezine and aromatase inhibitors are suspected of causing LS. (the latter is an estrogen blocker). By reverse logic then, blocking estrogen brings on LS, then having estrogen prevents or inhibits it.
Also, from pg 340 of article, "Thyroid disease seems to be the most common finding in these patients (12–30%)" AND, "The presence of autoantibodies in LS patients is very common, namely extracellular matrix 1 protein (67%)19, antibasement membrane (BP180 and BP230) (30–80%)20,21, and antithyroid antibodies (9%)22. Autoantibodies can be present in as many as 74% of women22 ." (The 19, 20, 21, and 22 are footnote designations). This is a long involved, but recent (2017) article. There are 96 footnotes that offer more info when I can get to them. These darn jobs sure do interfere with one's personal life.
Now, the question is which antibody is triggering the inflammatory response. The lack of estrogen idea fits well with the two "peaks" of this disease, namely pre-pubertal girls and post-menopausal women. It also fit s with males who, presumably, have little estrogen. More later as I digest this and some other articles. best, biscuit
