  • modest statistically significant inverse associations for total and calculated free testosterone, and modest positive associations for total and calculated free estradiol with CRP concentration
  • Estradiol concentrations were also weakly positively associated with WBC count
  • SHBG was weakly inversely associated with WBC
  • ...21 more annotations...
  • An association between testosterone and WBC count was not observed
  • These findings are consistent with the hypothesis that in men higher androgen concentration is anti-inflammatory, and higher estrogen concentration is pro-inflammatory.
  • the probability of elevated CRP concentrations (≥ 3 mg/L) decreased with higher total and calculated free testosterone concentrations, while the probability increased with higher total and calculated free estradiol concentrations
  • there is ample evidence supporting the immunosuppressive effect of androgens
  • The incidence of autoimmune diseases is higher in androgen-deficient men
  • Studies have shown that the induction of hypogonadism in older men is followed by a significant increase in IL-6 concentrations (Khosla et al. 2002), a potent stimulator of inflammation, and that activation of the androgen receptor exerts a direct anti-inflammatory effect
  • It has been suggested that the mechanisms for the immunosuppressive effect of androgens could be either a direct effect on the expression of inflammatory genes (Bellido et al. 1995; Asirvatham et al. 2006), or an indirect effect through inhibition of nuclear factor-kB activation
  • Estradiol is the major biologically active estrogen, and about 80% is formed in adult men from the aromatization of testosterone primarily in the adipose tissue
  • estrogen can stimulate the transcription factor C/EBP-β, which is involved in CRP transcription
  • Most prior cross-sectional studies have observed inverse associations between androgen concentrations and inflammatory biomarkers
  • A recent study in Chinese men showed that lower concentrations of total and calculated free testosterone were associated with higher CRP concentration
  • Data from the Boston Area Community Health Survey also reported inverse associations between testosterone and CRP concentrations
  • Total testosterone was inversely associated with WBC count (Tang et al. 2007; Schneider et al. 2009; Brand et al. 2012), but calculated free testosterone was not associated with WBC
  • The first trial found a decrease in CRP, interleukin-1β (IL-1β), and tumor necrosis factor-α (TNFα) but no changes in IL-6 and IL-10 concentrations between the active treatment and placebo arms
  • the majority of studies in the literature have not observed statistically significant associations between estradiol and inflammatory biomarkers in men, although several of them observed point estimates in the positive direction
  • total testosterone and estradiol compete for binding to SHBG, and seem to have opposite effects on the concentration of inflammatory biomarkers
  • A small randomized controlled trial of estrogen replacement therapy in prostate cancer patients showed an increase in CRP in the active treatment group versus the comparator group
  • Obese men are known to have lower androgen concentrations compared to their normal-weight counterparts
  • The strongest suggestion of an interaction was the inverse association between androstanediol glucuronide and CRP concentrations in obese participants, while the association was positive in the non-obese
  • A recent Chinese cross-sectional study observed stronger inverse associations between total testosterone and CRP concentrations in individuals with a BMI of 27.5 kg/m2 or greater
  • our results suggest that total and calculated free testosterone are modestly inversely associated with CRP concentrations, and that total and calculated free estradiol are modestly positively associated with CRP and WBC

    Study results suggest that higher Testosterone and lower Estrogen levels provide anti-inflammatory effects in men.  The inflammatory biomarker assessed here was CRP.  Low total and calculated free Testosterone was associated with an increase in CRP.  In contrast, total and free Estrogen was associated with an increase in CRP.  Estradiol increased WBC count and SHBG was inversely related to WBC count in this study.

    Total and free Estradiol associated with increased CRP in men.  This study found that it also correlated with WBC count as well.   Not new, but builds on the accumulative literature that high aromatase activity and estrogen production in men produces inflammation.

    Ferritin is increased as a byproduct of the inflammation, which studies suggest, are the result of TAMs. Some ferritin is also likely the result of release from cell death. L-ferritin is the most prevalent in cancer. Elevated ferritin is associated with a poor prognosis in many cancers. It also correlates with CRP, WBC in this study. 1 mg/ml of serum ferritin correlates to 8mg of stored Fe.

  • when vitamin C was supplemented with vitamin E in healthy adults, it increased the production of cytokines IL-1 beta and TNF-alpha
  • vitamin C acts to modulate the levels of cytokines to prevent them from fluctuating in either direction
  • vitamin C also acts as an important antioxidant to the cells of the immune system.
  • human leukocytes, neutrophils, in particular, possess the ability to transport the oxidized form of vitamin C across its membrane to use as a defense mechanism against ROS produced during an immune response
  • Vitamin C also can recover other endogenous antioxidants in the body such as vitamin E and glutathione, returning them to their active state
  • vitamin C can decrease the activation of NF-kB
  • can reduce harmful nitrogen-based compounds such as N-nitrosamines and nitrosamides, both of which are carcinogenic 
  • subjects taking oral vitamin C supplementation saw a 60% to 90% reduction in oxidative stress compared to a placebo control

  • 8 g doses of oral vitamin C
  • there is a negative correlation between age and serum levels of vitamin C
  • Patients with COVID-19 will likely also experience depletion in serum levels of vitamin C as a direct result of the upregulation of the immune system to combat the infection
  • Colunga et al. suggested that oral vitamin C can be combined with oral Quercetin, an antiviral flavonoid, to improve Quercetin’s ability to block viral membrane fusion of SARS-CoV-2
  • high doses of 1-2 g/day of oral vitamin C could prevent other upper respiratory infections
  • It appears vitamin C supplementation by itself does not provide a striking benefit in preventing COVID-19 infection for those without a deficiency

      Flawed statement. What is normal? Vitamin D. Many variables effect levels and dose, including the two compartment kinetics and absorption.
  • Hiedra et al. were able to show decreases in inflammatory biomarkers, such as D-dimer and ferritin
  • some evidence to support that prophylactic use of vitamin C helps reduce the severity of respiratory infection symptoms once a subject has already been infected
  • oral vitamin C in combination with zinc provided the largest amount of antibody titers 42 days

      Either these studies are designed to fail or the authors are lacking some basic understanding of pharmacokinetics and pharmacodynamics with vitamin C.
  • Fowler et al. aimed to see if a high-dose vitamin C infusion would benefit patients affected by ARDS, but they were unable to conclude that vitamin C infusion, compared to a placebo, could decrease vascular inflammation and damage in ARDS

      They are kind of make the point from my earlier note.
  • continuous vitamin C infusion at a rate of 60 mg/kg/day for four days decreased the need for mechanical ventilation and vasopressor use but had no significant effect on overall mortality

      Again, designed to fail or ignorance designed the study which failed
  • Carr et al. suggested that high-dose IV vitamin C is most effective when treating sepsis as septic patients receiving the normal daily recommendations through diet still showed decreased vitamin C levels
  • High-dose IV vitamin C treatment has also been shown by Kakodkar et al. to decrease syndecan-1, an endothelial glycocalyx that contributes to mortality in septic patients
  • combined with hydrocortisone and thiamine, septic patients treated with 1.5 g of IV vitamin C every six hours showed a distinct decrease in their SOFA scores and none of the patients treated developed organ failure

  • reduced overall mortality
  • reduced overall mortality
  • propose the use for high-dose vitamin C to aid in the treatment of septic shock-induced hypotension
  • treatment of severe sepsis using a high dose (up to 200 mg/kg/day) of IV vitamin C was explored in phase I, a double-blind, randomized, placebo-controlled trial by Fowler et al. [75]. Their findings included a reduction in SOFA scores and decreased vascular injury compared to a placebo control group, all while showing minimal adverse side effects

      High dose here is laughable. Again, duration and frequency also.
  • Maintaining a daily intake of 75 and 100 mg for men and women, respectively, as recommended by the U.S. Institute of Medicine
