Selenium and HIV/AIDS, Selenium and Vitamin C, and Vitamin E PDF Print E-mail

By George. D. Henderson (AHCS)
 

The following quote is from a Life Extension Foundation newsletter on a trial using Selenium in HCV. A lot of what it says is applicable to HCV infection, including the influence of poor nutrition on seroconversion.

One-hundred seventy-four participants completed the nine-month treatment period. Not surprisingly, blood selenium levels rose in the group that received the mineral. Greater selenium levels predicted a decline in HIV viral load, which subsequently predicted increased CD4 counts. Participants in the selenium group who did not respond were found to have a greater incidence of poor adherence to the treatment regimen. No adverse events occurred.

Although the mechanism of selenium against HIV infection has not been defined, one hypothesis suggests that the mineral’s antioxidant property repairs the damage inflicted on immune cells by oxidative stress, which is increased in HIV patients. Additionally, the HIV-1 virus may need selenium to produce some of its enzymes, which contributes to depletion of its host’s selenium reserves. The authors note that chronically ill or impoverished populations frequently have dietary deficiencies, and the resulting increase in oxidative stress can increase the virulence of some pathogenic viruses.

The authors conclude that "Given the challenges of using conventional pharmacotherapy to achieve and maintain virologic suppression in HIV-spectrum disease, our results support the use of selenium as a simple, inexpensive and safe adjunct therapy."

Because of their disease, patients with HIV/AIDS have nutritional deficiencies, and are subject to much greater oxidative stress than healthy people. In 1985, the Life Extension Foundation was among the first organizations to propose that patients with HIV/AIDS would benefit from taking high doses of antioxidants. Since then, many scientific studies have examined a wide range of nutrients and supplements for use in HIV/AIDS.

Selenium is required for proper functioning of the immune system (Look MP et al 1997). It is also essential in the synthesis of glutathione. Selenium’s many benefits include protecting the central nervous system from dementia caused by HIV (Shor-Posner G et al 2002a) and infection with Mycobacterium tuberculosis (Shor-Posner G et al 2002b); slowing the loss of T-cells (Look MP et al 1997); and decreasing the effect of inflammatory cytokines, which may reduce the risk of developing neurological damage (Bjugstad KB et al 1998; Ryan LA et al 2001; Seilhean D et al 1997), Kaposi's sarcoma (a common HIV-associated cancer), and wasting syndrome. Selenium also suppresses the enhancing effect of cytokines on HIV replication (Hori K et al 1997; Tolando R et al 2000).

In the latest edition of the LEF newsletter http://www.lef.org/newsletter/2007/
(tho it hadn't been archived yet when I wrote this) it is claimed that large dose of ascorbic acid can interfere with the absorption of selenium, which should be taken at least an hour bafore or 20 mins after vitamin C. This has a nice symmetry with the enhancing effect of Vitamin C on iron absorption, giving 2 reasons to be careful about the timimg of Vitamin C doses in HCV.

And also, this about vitamin E:
Increasing evidence indicates that it may be dangerous to use to alpha-tocopherol form of vitamin E without also taking gamma-tocopherol. According to the Proceedings of the National Academy of Sciences, alpha-tocopherol displaces critically important gamma-tocopherol in the cells. While alpha-tocopherol inhibits lipid peroxidation, gamma tocopherol is needed to quench dangerous free radicals such as peroxynitrite.

Studies show that when sesame lignans are added to the diet of rats, a measurement of free radical activity is reduced by 82 percent. Sesame lignans augment the antioxidant effects of both alpha and gamma-tocopherol. A human study showed that gamma-tocopherol plus sesame lignans was 25 percent more effective at suppressing measurements of free radical damage than gamma-tocopherol and tocotrienol

Most commercial vitamin Es are D-alpha-tocopherol. Rice Bran Oil is a cheap source of gamma tocopherol and tocotrienols and I drink a spoonful every day(Wheat Germ oil is richer, but much more expensive); sesame seeds, the source of the lignans.
