  • affect approximately 5 to 8 % of the US population
  • the incidence and prevalence of autoimmune diseases are rising
  • Type 1 diabetes (T1D), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and inflammatory bowel disease (IBD) account for the majority of the patients with autoimmune diseases
  • ...9 more annotations...
  • Autoimmune diseases are characterized by a breakdown of mechanisms that allow the immune system to distinguish between self and nonself and maintain immunologic self-tolerance
  • Tregs, which are important in the maintenance of peripheral immune tolerance.
  • Several subtypes of Tregs exist, the most well studied being CD4+ cells that express high-level CD25 and the transcription factor forkhead box P3 (FOXP3)
  • Treg deficiency or dysfunction is associated with autoimmune disease
  • In clinical studies, decreased levels of circulating CD25+CD4+ T cells have been reported in patients with autoimmune disease
  • These data have led to the hypothesis that augmentation of Tregs may be a useful therapeutic strategy in autoimmune disease
  • Treg augmentation has resulted in clinical improvements in numerous animal models of autoimmune diseases
  • the administration of in vitro expanded CD4+CD25highCD127-Tregs has been found to be safe and may help to preserve β-cell function in children with T1D
  • ability of IL-2 to augment the numbers and function of CD4+ Tregs.

    Great article.  Immune dysfunction plays role in autoimmune disease and cancer.  Treg cells sit at the center of autoimmunity.  This artice highlights the different uses: low dose IL2 therapy to augment Tregs and reduce autoinflammation and high dose IL2 to augment Treg cells in the fight against cancer.

  • Padayatty and colleagues showed that high-level ascorbic acid plasma concentrations could only be achieved by intravenous administration
  • No patient in the low or high dose ascorbic acid treatment arms of this study suffered any identifiable adverse event
  • a pharmacologic ascorbic acid treatment strategy in critically ill patients with severe sepsis appears to be safe
  • ...7 more annotations...
  • subnormal plasma ascorbic acid levels are a predictable feature in patients with severe sepsis
  • Ascorbic acid depletion in sepsis results from ascorbic acid consumption by the reduction of plasma free iron, ascorbic acid consumption by the scavenging of aqueous free radicals (peroxyl radicals), and by the destruction of the oxidized form of ascorbic acid dehydroascorbic acid
  • Sepsis further inhibits intracellular reduction of dehydroascorbic acid, producing acute intracellular ascorbic acid depletion
  • Ascorbic acid treated patients in this study exhibited rapid and sustained increases in plasma ascorbic acid levels using an intermittent every six hours administration protocol
  • Septic ascorbic acid-deficient neutrophils fail to undergo normal apoptosis. Rather, they undergo necrosis thereby releasing hydrolytic enzymes in tissue beds, thus contributing to organ injury
  • We speculate that intravenous ascorbic acid acts to restore neutrophil ascorbic acid levels
  • Repletion of ascorbic acid in this way allows for normal apoptosis, thus, preventing the release of organ damaging hydrolytic enzymes.

    Study finds IV vitamin C in patients with sepsis is very safe and blunts the effects (endothelial damage, end organ damage...) of sepsis.  Of note, the IV vitamin C group reached serum levels of ascorbic acid of 1,592 to 5,722 micromol/L.  The IV groups maintained elevated serum C levels for up to 96 hours post infusion.
