I would like to know if hormone therapy increases or decreases or has no effect on immunity. I have my wife's fears that since I have cancer I am among the most vulnerable4 to Covid 19. My doctor, however, advised me the opposite, that it does not, that hormone therapy, unlike chemotherapy does not affect immunity.
Researching and thinking on my own, I have to think that a reduction in testosterone would probably NOT affect immunity. In fact, my white blood cell count has always remained in the normal range, under hormone therapy and during a four-year vacation, in which my PSA level rose and fell from <0.1 to 35, and back to <0.1. During the same period my WBC ranged from low of 4 to high of 7, all normal, except one strange test of 13, in 2015, (above normal) and several 7 lately( above normal). In general, I understand that white blood cells increase to fight invader cells, including many things such as cancer cells or bacteria or virus or pestides or other chemicals. But there are many types of white blood cells, each with different purposes. It's a complex matter, not easily understood.
Lately after my return to hormone therapy, Lupron injection every three months, with Xtandi nightly, I have watched my blood panel carefully, and all the white blood cells seem to remain in normal ranges, with one exception on the last test: my eosinophil percent rating went to 6%, highest ever, while eosinophil absolute vascilated but within normal range, with a slight upward bias. Trying to understand whether this is good or bad, I researched the net a bit and it seems a high eosinophil level can indicate a hereditary disorder, hiv (virus), or possibly a chemical reaction to medication, (Xtandi?), cancer, or a reaction to parasitic invasion of some sort. My unprofessional guess is that it is basically meaningless. However, it is the only thing on my blood panel that is drifting out of normal range, so I am currently attentive to it.
I have seen that older people with cancer are more vulnerable to Covid 19, and especially with other complications such as high blood pressure. I am nearly 75 with both. But I sense that I am quite immune, generally. I have been free from flu for a couple of years, in spite of not taking vaccine. Last vaccine seemed to cause a brief spat with flu a few years ago. I have had a chronic cough years ago, but I had a shot for chronic bronchitis which seems to have been effective against that.
I would like to see if anyone has comments on this.
