Connection between HIV and Vitamin D: Implications, impact, supplement options, and further details
People living with HIV who are on antiretroviral therapy (ART) are at an increased risk of developing vitamin D deficiency. This is primarily due to interactions between certain ART drugs and vitamin D metabolism.
Research has shown that some antiretroviral drugs, such as tenofovir disoproxil fumarate (TDF), can reduce bone mineral density by influencing vitamin D metabolism and calcium absorption. This increases the risk of vitamin D deficiency and related bone disorders. Other protease inhibitors and non-nucleoside reverse transcriptase inhibitors may also alter vitamin D metabolism, although the mechanisms and clinical significance vary.
The concern about vitamin D deficiency in HIV-positive individuals on ART is significant because it can exacerbate the risk of bone disease, such as osteopenia and osteoporosis, which are already more common in this population. To counteract these effects, supplementation with vitamin D and calcium is often recommended to improve bone health.
In severe cases of vitamin D deficiency, a daily dose of 7,000 IU was found to be the most effective in restoring vitamin D levels, with levels increasing after 12 months of treatment. Once people reach a sufficient amount of vitamin D in their bodies, researchers recommend a maintenance dose to keep levels stable.
It's important to note that while researchers are still unclear about whether vitamin D supplementation has any effect on viral load, avoiding vitamin D deficiency can help improve immune health and decrease the risk of autoimmune conditions.
Increased vitamin D levels may also reduce the risk of potential HIV complications, such as hyperparathyroidism, microbial infections like tuberculosis, chronic inflammation, bone turnover, and the amount of lymphocytes that HIV destroys, which are cells that help stimulate and regulate the immune system.
The Department of Health and Human Services suggests changing certain drugs, such as switching from TDF to tenofovir alafenamide, for HIV-positive individuals taking antiretrovirals that decrease the amount of vitamin D in the body. Many studies have shown that vitamin D supplementation is safe for individuals living with HIV.
However, high doses of vitamin D may pose risks, as calcidiol (a form of vitamin D) increasing beyond 100 nanograms per milliliter, or calcium in the blood increasing beyond 2.70 millimoles per liter, could produce adverse effects.
Research has found that up to 100% of those living with HIV-1 have insufficient vitamin D levels, and at least 30% have a vitamin D deficiency. Factors contributing to vitamin D deficiency in both HIV-positive and HIV-negative individuals include lack of sun exposure, lack of dietary sources of vitamin D or malabsorption, dark skin pigmentation, obesity, smoking, intravenous drug use, liver disease, kidney disease, older age, and chronic inflammation.
Vitamin D plays a crucial role in the body's immune response and has anti-inflammatory and antimicrobial effects. Researchers are still investigating whether regular vitamin D supplementation can prevent or alter the course of inflammatory or autoimmune conditions in those at risk.
In conclusion, managing vitamin D deficiency is an essential aspect of care for individuals living with HIV on ART. Regular monitoring and possible supplementation are necessary to mitigate bone and immune health complications. It's crucial for healthcare providers to consider the potential impact of ART on vitamin D levels and tailor treatment plans accordingly.
