Israelis find vitamin D helps against liver diseases

Research teams first to discover benefits of treatment against hepatitis C and cirrhosis.

Two Israeli research teams have separately become the first to discover two different benefits from vitamin D against common liver diseases – hepatitis C and cirrhosis.

One involved the mechanism in human cells in the lab, while and the other proved itself on liver tissue in rats. The two discoveries have not yet been tested clinically.

Prof. Ran Tur-Kaspa, from the Rabin Medical Center- Beilinson Campus, and his team worked on hepatitis C, the major factor in chronic liver disease that can lead to cirrhosis. It is also the main cause in the Western world of organ failure requiring a liver transplant and is one of the causes of primary liver cancer.

Antiviral treatment can help in half the cases, but the side effects are serious even if the treatment is effective.

Tur-Kaspa, a liver specialist and researcher who is dean of the Galilee Medical Faculty in Safed, said there is a constant search for medications and other technologies that are more effective and accompanied by fewer side effects.

He and his team investigated ordinary vitamin D, which is already taken by many people as prevention for numerous diseases, to see whether it had any effect on hepatitis C and on liver cells that host it. They discovered, and published in Hepatology, a peer-reviewed medical journal, that vitamin D directly halts the activity of viruses in general and hepatitis C in particular. They also found that a system for actively producing vitamin D is found in liver cells and can activate the immune system and repress the virus.

The research showed without doubt that vitamin D functions in the liver cell, and it causes an increase in naturally produced interferon and repression of the production of the virus, said Dr.

Romy Zemel, who was part of the team. The research proves that integrating the use of interferon and vitamin D boosts the effects synergistically, beyond the effects of each alone.

Interferons are a family of naturally occurring proteins that are made and secreted by immune-system cells. Thus, with the right combination, said the Beilinson researchers, one could destroy the virus. Their discovery was made serendipitously.
