The association of vitamin D with hepatitis B virus replication: Bystander rather than offender.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

Low vitamin D is frequent in hepatitis B virus (HBV)-infected patients and several studies show an inverse association of serum vitamin D level with HBV viral load.

However, the causal relationship remains unclear.

Who Took Part

By PubMed's age tags, the people studied were adults and middle-aged adults, both men and women.

HBV carriers receiving regular 6-month surveillance without current antiviral treatment or cirrhosis were invited to participate into this trial.

How the Study Was Run

The design is described as randomized.

Random assignment meant chance, not the researchers, decided who got Vitamin D, K2, Magnesium and Zinc and who got the comparison, which limits bias.

The markers of HBV replication included serum HBV DNA and quantitative HBsAg (qHBsAg) levels.

Those with undetectable HBV DNA or sufficient vitamin D levels, cancer or electrolyte imbalance were excluded.

What Was Measured

PubMed files the paper under topics including Criminals, DNA, Viral, Hepatitis B, Hepatitis B Surface Antigens, Hepatitis B e Antigens, Hepatitis B virus and Virus Replication.

Author keywords: HBV DNA, Quantitative HBsAg and Vitamin D.
