Abstract
Vitamin D is an important immune modulator which plays an emerging role in inflammatory and metabolic liver diseases, including infection with hepatitis C virus (HCV). In contrast, the relationship between vitamin D metabolism and chronic hepatitis B is less well characterized. Therefore, we quantified 25-hydroxyvitamin D [25(OH)D3 ] serum levels in a cohort of 203 treatment-naïve patients with chronic hepatitis B virus (HBV) infection and tested for their association with clinical parameters of chronic hepatitis B. 69 (34%), 95 (47%), and 39 (19%) out of 203 patients had severe vitamin D deficiency [25(OH)D3 <10ng/mL], vitamin D insufficiency [25(OH)D3 ≥10ng/mL and <20ng/mL], or adequate vitamin D serum levels [25(OH)D3 ≥20ng/mL], respectively. In both uni- and multivariate analyses, HBV DNA viral load (log10 IU/mL) was a strong predictor of low 25(OH)D3 serum levels (p=0.0007 and p=0.000048, respectively), and vice versa. Mean 25(OH)D3 serum concentrations in patients with HBV DNA <2000 IU/mL vs. ≥2000 IU/mL were 17 vs. 11 ng/mL, respectively (p<0.00001). In addition, hepatitis B early antigen (HBeAg) positive patients had lower 25(OH)D3 serum levels than HBeAg negative patients (p=0.0013). Finally, 25(OH)D3 and HBV DNA serum levels showed inverse seasonal fluctuations. Conclusions: Low 25(OH)D3 serum levels are associated with high levels of HBV replication in patients with chronic hepatitis B. This represents a major difference to chronic hepatitis C, were numerous previous studies have shown a lacking correlation between HCV viral load vitamin D serum levels. Inverse seasonal fluctuations of 25(OH)D3 and HBV DNA serum levels are suggestive for a functional relationship between both variables. (HEPATOLOGY 2013.).

i think low vit d is due to immune system mulfunction since all chronic diseases from all virus infections to cancers have low vit d and all improve increasing vit d
all viruses use ways to suppress immune function otherwise they cannot stay in our bodies (same thing cancer cells) and all target vitamin d...maybe the whole thing is about nagalase, vit d, vdr, gcmaf and immune system activation because all chronic diseases have low vit d, abnormal nagalase and deficent immune activation

Low 25(OH)D3 serum levels n relation with HBV is a cause or a result ?
Active HBV is becuse we have low vit D or we have low vit D because we have HBV?
Do you know any study that rellate the suplimantary vit D with HBV ?

IMPORTANT: If You Take Vitamin D, You Need K2
This is a really crucial point: If you opt for oral vitamin D, you need to also consume in your food or take supplemental vitamin K2.
"There are so many people on the vitamin-D-mega-dose bandwagon, taking more and more of vitamin D. And it could absolutely be causing harm if you are lacking the K2 to complete the job to get the calcium where it's supposed to be," Rheaume-Bleue warns.
"We don't see symptoms of vitamin D toxicity very often. But when we do, those symptoms are inappropriate calcification. That's the symptom of vitamin D toxicity. And it is actually a lack of vitamin K2 that can cause that..."
While the ideal or optimal ratios between vitamin D and vitamin K2 have yet to be elucidated, Rheume-Bleue suggests about 150-200 micrograms of K2 will meet the need for the "average" healthy person.
The latest vitamin D dosing recommendations, which call for about 8,000 IU's of vitamin D3 per day if you're an adult, means you'd need in the neighborhood of 800 to 1,000 micrograms (0.8 to 1 milligram/mg) of vitamin K2, but the jury is still out.
"My earlier recommendation was not taking into account people who were doing high dose of vitamin D supplementation," Rheaume-Bleue says. "That's where it gets a little bit more technical. It seems that for the average person, around 200 to 280 micrograms will activate your K2 proteins and do a lot of good for your bones and your heart. If you're taking high levels of vitamin D... then I would recommend taking more K2."
The good news is that vitamin K2 has no toxicity. No toxic effects have ever been demonstrated in the medical literature.
"The reason why K2 doesn't have potential toxic effect is that all vitamin K2 does is activate K2 proteins. It will activate all the K2 proteins it finds. And if they're all activated and you take extra K2, it simply won't do that. That's why we don't see a potential for toxicity the way we do with vitamin A or D," she says.

intersting article about vit d and vitamin k2, only this type of k2: MK-7 (Vitamin K2 as Menaquinone-7 from Natto Extract).looks like some research is proving vit d toxicity is due to k2 deficency but anyway it makes sense to combo d3 and k2 together especially for the prevention effect of both d3 and k2 (mk7 from natto) on liver cancer
