Low-Dose Hydrocortisone for Treatment of Chronic Fatigue Syndrome, September 23/30, 199... - 0 views

  •  
    this study revealed symptom improvement with hydrocortisone treatment in those with CFS. Pre/post treatment was with serum cortisol and not salivary cortisol.  This is a weakness of the study.  The starting dosage of 25-30 mg hydrocortisone is high and with inadequate evaluation, this high dosage could have resulted in high dosage and adrenal suppression.

Intravenous Ascorbate as a Tumor Cytotoxic Chemotherapeutic Agent - 0 views

  • There is a 10 — 100-fold greater content of catalase in normal cells than in tumor cells
  • induce hydrogen peroxide generation
  • Ascorbic acid and its salts (AA) are preferentially toxic to tumor cells in vitro (6 — 13) and in vivo
  • ...36 more annotations...
  • related to intracellular hydrogen peroxide generation
  • only be obtained by intravenous administration of AA
  • Preferentially kills neoplastic cells
  • Is virtually non-toxic at any dosage
  • Does not suppress the immune system, unlike most chemotherapy agents
  • Increases animal and human resistance to infectious agents by enhancing lymphocyte blastogenesis, enhancing cellular immunity, strengthening the extracellular matrix, and enhancing bactericidal activity of neutrophils and modulation of complement protein
  • Strengthens the structural integrity of the extracellular matrix which is responsible for stromal resistance to malignant invasiveness
  • 1969, researchers at the NCI reported AA was highly toxic to Ehrlich ascites cells in vitro
  • In 1977, Bram et al reported preferential AA toxicity for several malignant melanoma cell lines, including four human-derived lines
  • Noto et al reported that AA plus vitamin K3 had growth inhibiting action against three human tumor cell lines at non-toxic levels
  • Metabolites of AA have also shown antitumor activity in vitro
  • The AA begins to reduce cell proliferation in the tumor cell line at the lowest concentration, 1.76 mg/dl, and is completely cytotoxic to the cells at 7.04 mg/dl
  • the normal cells grew at an enhanced rate at the low dosages (1.76 and 3.52 mg/dl)
  • preferential toxicity of AA for tumor cells. >95% toxicity to human endometrial adenocarcinoma and pancreatic tumor cells (ATCC AN3-CA and MIA PaCa-2) occurred at 20 and 30 mg/dl, respectively.
  • No toxicity or inhibition was demonstrated in the normal, human skin fibroblasts (ATCC CCD 25SK) even at the highest concentration of 50 mg/dl.
  • the use of very high-dose intravenous AA for the treatment of cancer was proposed as early as 1971
  • Cameron and Pauling have published extensive suggestive evidence for prolonged life in terminal cancer patients orally supplemented (with and without initial intravenous AA therapy) with 10 g/day of AA
  • AA, plasma levels during infusion were not monitored,
  • the long-term, oral dosage used in those experiments (10 g/day), while substantial and capable of producing immunostimulatory and extracellular matrix modulation effects, was not high enough to achieve plasma concentrations that are generally cytotoxic to tumor cells in culture
  • This low cytotoxic level of AA is exceedingly rare
  • 5 — 40 mg/dl of AA is required in vitro to kill 100% of tumor cells within 3 days. The 100% kill levels of 30 mg/dl for the endometrial carcinoma cells and 40 mg/dl for the pancreatic carcinoma cells in Figure 2 are typical
  • normal range (95% range) of 0.39-1.13 mg/dl
  • 1 h after beginning his first 8-h infusion of 115 g AA (Merit Pharmaceuticals, Los Angeles, CA), the plasma AA was 3.7 mg/dl and at 5 h was 19 mg/dl. During his fourth 8-h infusion, 8 days later, the 1 h plasma level was 158 mg/dl and 5 h was 185 mg/dl
  • plasma levels of over 100 mg/dl have been maintained in 3 patients for more than 5 h using continuous intravenous infusion
  • In rare instances of patients with widely disseminated and rapidly proliferating tumors, intravenous AA administration (10 — 45 g/day) precipitated widespread tumor hemorrhage and necrosis, resulting in death
  • Although the outcomes were disastrous in these cases, they are similar to the description of tumor-necrosis-factor-induced hemorrhage and necrosis in mice (52) and seem to demonstrate the ability of AA to kill tumor cells in vivo.
  • toxic effects of AA on one normal cell line were observed at 58.36 mg/dl and the lack of side effects in patients maintaining >100 mg/dl plasma levels
  • Although it is very rare, tumor necrosis, hemorrhage, and subsequent death should be the highest priority concern for the safety of intravenous AA for cancer patients.
  • Klenner, who reported no ill effects of dosages as high as 150 g intravenously over a 24-h period
  • Cathcart (55) who describes no ill effects with doses of up to 200 g/d in patients with various pathological conditions
  • following circumstances: renal insufficiency, chronic hemodialysis patients, unusual forms of iron overload, and oxalate stone formers
  • Screening for red cell glucose-6-phosphate dehydrogenase deficiency, which can give rise to hemolysis of red blood cells under oxidative stress (57), should also be performed
  • any cancer therapy should be started at a low dosage to ensure that tumor hemorrhage does not occur.
  • patient is orally supplementing between infusions
  • a scorbutic rebound effect can be avoided with oral supplementation. Because of the possibility of a rebound effect, measurement of plasma levels during the periods between infusions should be performed to ensure that no such effect takes place
  • Every effort should be made to monitor plasma AA levels when a patient discontinues intravenous AA therapy.
  •  
    Older study, 1995, but shows the long-standing evidence that IVC preferentially is cytotoxic to cancer cells.`

Acute prooxidant effects of vitamin C in... [Free Radic Biol Med. 2005] - PubMed - NCBI - 0 views

  •  
    This study found a pro oxidant effect of the addition of 5 grams of IV vitamin C with EDTA chelation.  As dosing of IV vitamin C goes, 5 grams is quite small.  Vitamin C has been shown to have varying effects (pro oxidant versus antioxidant) dictated by the dosage.  One wonders if higher dosing IV vitamin C provides antioxidant effects?

Differences in the Apparent Metabolic Clearance Rate of Testosterone in Young and Older... - 0 views

  •  
    Age seems to predict metabolism of testosterone in those receiving testosterone therapy.  Older men appear to have slower metabolism of testosterone.  This implies that one can likely dose "older" men at lower dosages.

  •  
    animal study finds vitamin C improves hypertension via renovascular source and oxidative stress.  The dosage was 150 mg/kg/day.  This would be equivalent to 10,800 grams daily for a 72 human.  But what about a 200 lb male or female?  That would be 13,650 grams of vitamin C daily.

    Testosterone shown to improve GLUT 4 and IRS-1 expression with low dose short term therapy; in contrast, high dose, prolonged therapy shown to down regulate IRS-1 and GLUT 4 expression.  This shows the importance of using saliva for evaluation versus serum.  Serum testing routinely leads to over treatment with high dosages of testosterone.

OASIS - 0 views

  •  
    I look forward to the published results of this study as this abstract references the WHI as the "same entry" criteria.  I imagine the HRT would be the same too, but will wait to see.  There is a serious problem with proper reporting of synthetic estrogens as bioidentical estrogens and synthetic progestins as bioidentical progesterone;  Also, what is the dosage. Most individuals are massively overdosed.  This study was said to be a "landmark".  Could just be don't use synthetic hormones: which is what the WHI said.

  •  
    this study revealed increased breast cancer risk in women on "estrogen" and "testosterone" therapy.  Now, several problems here: first, are these synthetic hormone or bioidentical.  Second, the dosages appear, in what is written, to be supra physiologic.  Third, giving supra physiologic estradiol and testosterone will obviously create imbalances and growth potential.  Fourth, how were the women evaluated prior to starting hormone therapy and then were they remonitered (unlikely), fifth, were hormone metabolites evaluated (too, also unlikely).  This study has serious flaws and very little can be extrapolated other than: don't take supra physiologic hormone levels without appropriate evaluation.  Enough said

Curcumin Extract for Prevention of Type 2 Diabetes - 0 views

  •  
    Curcumin, best taken in form from Turmeric, found to significantly prevent diabetes progression and improve Beta islet cell function.  The dosage used in this 9 month trial was 1500 mg taken in divided dosing.  A major point is that turmeric actually improved pancreatic beta islet cell function and prevented Diabetes.  As "health" care providers our focus should be on prevention of disease.

Is Timing Everything? New Insights into Why the Effect of Estrogen Therapy on Memory Mi... - 0 views

  • Women who have an oophorectomy before the normal age at menopause show an increased risk for cognitive impairment or dementia later in life unless they are treated with estrogen until the normal age at menopause
  • SIRT1 has been implicated in the disruption of mitochondrial bioenergenetics in Alzheimer's disease and mild cognitive impairment
  • the increase in dementia observed with CEE/MPA rather than CEE alone suggests potential deleterious effects of MPA on brain function in older women
  • ...1 more annotation...
  • SIRT 1 as a potential mediator of the impact of E2
  •  
    Early estrogen therapy in perimenopause and early menopause, with Estradiol, provides more health benefits than later therapy.  This article looked at Estrogen's effects on a woman's brain.  This likely has its origins in the change in estrogen receptors. The signal is not changing, but the reception of that signal is.  How else can one explain a different response to the same hormone dosage?

Testosterone replacement in prostate cancer survivors with hypogonadal symptoms - Leibo... - 0 views

  •  
    Good article.  This article (case series) found that 40% of the men included had no increase in PSA with Testosterone.  One point on the Testosterone dosage is that they used androgen, which is an overdose of Testosterone.  That gives 60% that the PSA did increase.  These men had higher PSA to begin with which leads to the suggestion that the prostate cells were abnormal.  Those men that had a prostatectomy were more likely to have little if any increase in PSA.  This study did use a the 5 alpha reductase inhibitor dutasteride.

  •  
    Review of the data points to poor quality of evidence dealing with DHEA in post-menopausal women with normal adrenal function.  Yet if DHEA is low, which is >95% produced by adrenals in women, then how can the adrenal function be "normal".   The meta-analysis found no improvement in libido and/or sexual function, and no improvement in lipids, glucose, weight... was noted.  Essentially not positive or negative effects were noted.  Abstract only available here, so dosage is a question.
