New info of concern to the group.
By now, most will know that ADT as monotherapy is not immunosuppressive. Testosterone [T] at normal-high levels is immunosuppressive. To that extent, those who had high T before ADT will have removed a risk factor. I don't know how low T has to go before we can ignore it as a risk factor. 350 ng/dL is the cutoff for hypogonadism. Many men are near this level at diagnosis. I doubt that ADT would confer much if any benefit to those men.
But now a new problem has raised its head. As most will know, men with PCa (as a group) have higher cardiovascular disease risk. In fact, in some vlog psts, Dr. Myers seemed more concerned about keeping patients from dying of CVD than PCa.
Well, it turns out that COVID-19 attacks the heart in 20% of patients in the general population. Could be higher in this group. Some patients present only with heart issues & lungs are clear. It's a scary idea that one might be entirely symptom-free yet have one's heart on the verge of giving out.
Ironically, a strong immune response to COVID-19 & the resulting high level of inflammation might contribute to a cytokine storm & heart damage. (Bring back my T. LOL) Those who are already managing inflammation may fare better.
There are situations where one does not want a robust immune response. Although one can say that COVID-19 causes heart damage in some, it may be the strength of the immune response that causes the damage.

"The Chinese Center for Disease Control and Prevention recently published the largest case series to date of COVID-19 in mainland China; the overall case fatality rate was 2.3% (1023 deaths among 44 672 confirmed cases), but the mortality reached 10.5% in patients with underlying CVD."

[3] New York Times.
"The study, led by Dr. Zhibing Lu at Zhongnan Hospital of Wuhan University, found that 20 percent of patients hospitalized with Covid-19, the illness caused by the coronavirus, had some evidence of heart damage.
"Many were not known to have underlying heart disease. But they often had abnormal electrocardiograms, like the patient in Brooklyn, in addition to elevated troponin levels, which sometimes soared to levels seen in patients with heart attacks.
"The risk of death was more than four times higher among these patients, compared with patients without heart complications."
Referring to the Italian case in [4]:
"... describing a previously healthy 53-year-old woman who developed myocarditis."
"... her electrocardiogram was abnormal, and she had high levels of troponin in her blood. Because of the coronavirus outbreak in Italy, doctors thought to test her and found she was infected."
"Dr. Enrico Ammirati, an expert in myocarditis at Niguarda Hospital in Milan who consulted on the case, said the patient’s heart problems were likely caused by her body’s immune response to the virus."
[4] Italian case [Jama]

Note that: "The cardiac subtype of troponin T {TnT} ... is released into the blood-stream when damage to heart muscle occurs." [5]
