A daily dose of vitamin D 'helps fight HIV'
Low levels of vitamin D may limit the effectiveness of HIV treatment in adults, scientists have found.Although most people diagnosed as HIV-positive can live a long and healthy life, some begin to struggle with their health over time.
This decrease is caused by the immune system can not respond effectively to common pathogens
HIV drugs work to improve the number of CD4 + T cells -. a vital immune cell type - in the body.
Dr. Amara Ezeamama, assistant professor of epidemiology and biostatistics at the University's School of Public Health of Georgia professor, said. "HIV destroys the body's ability to mount an effective response to pathogens
'Given the different levels of vitamin D, HIV-positive adults were recovered at different rates. a relationship between vitamin D and T CD4 + cells was found. '
Dr. Ezeamama conducted a longitudinal study of 18 months that the immune status of HIV-positive 398 adults was measured at baseline and at three, six, 12 and 18 months.
Dr. Ezeamama, said: "Due to the destructive effects of the immune HIV infection usually results in relatively quick death without treatment
The magic of antiretroviral therapy, name drugs for treatment. HIV lies in its ability to restore immune function.
'with antiretroviral drugs, people with HIV are starting to live longer.
' our goal was to understand if vitamin D deficiency limits the amount of immune recovery providing people HIV treatment. "
the vitamin D is relatively cheap. If you intervene with it, could give individuals infected with HIV a modest bump immune recovery that will likely result of the large public health impact of
Dr. Amara Ezeamama, University of Georgia
Researchers, through observation, related to increased immune function of whether or not individuals had adequate vitamin D.
levelsSpecifically, Dr. Ezeamama found that vitamin D helped CD4 + T cells in adults recover faster. T
CD4 + cells are a type of T cell that helps the immune system fight pathogens. .
For HIV-positive adults, CD4 + T cells are critical due to their weakened immune systems
Dr. Ezeamama found that participants with sufficient levels of vitamin D were recovered more of their immune function - in 65 CD4 + T cells average more - than those with vitamin D deficiency
the benefit of vitamin D sufficiency seemed higher for HIV-positive smaller and underweight adults.
During the study, participants were taking antiretroviral therapy, or HAART highly active, which usually consists of three or more drugs and is currently the most common - treatment for adults with HIV - and more effective.
The HAART take it daily.
"It's a cocktail of several drugs that control the virus, said Dr. Ezeamama.
"In addition to HAART, ensuring vitamin D sufficiency may also be useful in restoring immune function.
" As researchers, wanting to know what we can do to help.
'vitamin D is relatively cheap. If you intervene with it, could give individuals infected with HIV a modest bump immune recovery that will likely result to the great impact of public health. "
in the future, Dr. Ezeamama want to see how it affects vitamin D immune recovery and the results of long-term health in HIV-positive children.
"We are now in an era of hope for people with HIV," she said. "We know that HIV treatment works, and now people can live for decades with HIV.
"we can delay further progress of the disease and keep survivors in a better quality of life if we understand the factors that limit the effectiveness of HIV treatment."
the findings were recently published in the journal Clinical Nutrition.
