Catching 15 minutes of sunlight three times a week and drinking water instead of sugary drinks are two of the easiest and most natural ways to protect against liver cancer and other types of liver damage when you live with hepatitis B.

Sunlight doesn’t cure hepatitis B, but it spurs production of vitamin D, which appears to help prevent a number of cancers and other liver problems.

The liver appears to play a vital role in metabolizing vitamin D, and when you have healthy vitamin D levels, your body’s cells behave and grow normally. But when you have a vitamin D deficiency, communication between your cells breaks down, which can lead to abnormal cell growth and cancer.

Father’s Day, June 21, is a day to celebrate the contributions men make in their children’s lives. It’s also a good day for fathers to acknowledge how valuable they are to their families and how important it is to take care of their health.

Living with chronic hepatitis B can be challenging. Here are some things dads can do to take care of themselves or family members infected with hepatitis B.

1. Get outside and soak in some sunlight and some vitamin D. People with hepatitis B who have vitamin D deficiencies have higher rates of liver damage, cirrhosis and cancer. A healthy diet provides vitamin D, but 80 percent of our vitamin D comes from 15 minutes of exposure to sunlight two to three times a week. So get outside and walk, garden, exercise and soak in some healthy sunlight.

Despite Antiviral Treatment, Liver Cancer Risk Persists
Researchers have hoped that treating hepatitis B patients with antivirals would reduce both their viral loads and their liver cancer risk. However, a new study that followed 1,378 treated and 1,014 untreated patients over five years found antivirals did not reduce liver cancer rates as hoped.

The study tracked new liver cancer cases among patients infected with the hepatitis B virus (HBV) (average age 47, 65% male) who had been treated primarily with entecavir (Baraclude) for their high viral loads and liver damage. They compared that group’s liver cancer occurrence to those of patients whose “inactive” HBV infection did not require treatment.

Among the treated group, 70 patients (6.2%) developed liver cancer during the study period compared to only 11 (1.1%) in the untreated group. Notwithstanding  the ability of antivirals to reduce viral load, a life-long history of HBV infection and liver damage appeared to increase cancer risk, despite the reduction in viral load later in life.

What is especially disappointing is that liver cancer developed even in treated patients who had no history of cirrhosis (severe liver scarring) which increases cancer risk. Among the antiviral-treated patients:

  • • 20 of 223 HBeAg-negative patients who had cirrhosis at the start of treatment developed liver cancer.
  • • 15 of 316 HBeAg-negative patients who had no cirrhosis also developed liver cancer.
  • • Among the treated patients who developed liver cancer, 30 were positive for the hepatitis B “e” antigen (HBeAg) and 30 were HBeAg-negative.

How well the antiviral worked in patients also determined who remained cancer-free. Of the 246 patients who failed to achieve low or undetectable viral loads as a result of treatment, 36 (18.8%) patients developed liver cancer over the five-year study.

The risk of cancer was increased overall by male gender, underlying cirrhosis and older age in the treated group. Curiously, having high viral loads (HBV DNA) at the start of treatment did not appear to increase liver cancer risk.

The key message for doctors is that liver cancer risk remains despite a dramatic reduction in viral load, researchers noted. “…Patients on (antiviral) treatment that effectively suppressed viral replication are still at higher risk of liver cancer compared with patients with inactive stage chronic hepatitis B,” they concluded in the study published in the March issue of the journal Gut.

Persistent liver damage before the start of antiviral treatment, evidenced by elevated alanine aminotransferase (ALT) levels, may predispose patients to liver cancer, they also noted.

“The inactive group may have more intact immune response to HBV and therefore may also have entered the inactive stage early in life, with a shorter period of high viral replication and active hepatitis,” they wrote.

Vitamin D Appears to Help Prevent Liver Cancer
Recent studies show a diet rich in vitamin D can improve liver health in patients with hepatitis B. A new study from Emory University in Atlanta finds that people with high vitamin D levels have lower rates of liver cancer.

The researchers examined vitamin D levels and liver cancer risk among 520,000 participants in the European Prospective Investigation into Cancer and Nutrition between 1992 and 2010.

High HBV Viral Load Tied to Low Serum Vitamin D Levels

7 Comments

An interesting study published in Healio Hepatology:  “High HBV viral load tied to low serum vitamin D levels” discusses the relationship between the HBV viral load and vitamin D levels. In fact is shows seasonal fluctuations of HBV viral load associated with vitamin D levels. Vitamin D has been on the radar for years, but this interesting correlation between HBV virus flucuations and vitamin D levels warrants additional research to investigate how adequate vitamin D levels can positively impact treatment for those living with chronic HBV. Please refer to earlier blogs, Hepatitis B and Vitamin D and Got HBV? Adding Vitamin D to Your Diet for additional information.  As always, please talk to your doctor and have your serum vitamin D levels checked before making any drastic changes to your diet or supplements you may be taking. Don’t forget that vitamin D is the sunshine vitamin, so be sure to keep in mind the impact of the seasons on your levels. 

Patients with chronic hepatitis B who also were vitamin D deficient had significantly higher HBV DNA levels than patients with adequate vitamin D concentrations in a recent study.

In a retrospective study, researchers measured the serum levels of 25-hydroxyvitamin D (25OHD) in 203 treatment-naive patients with chronic hepatitis B seen between January 2009 and December 2012. Patients with 25OHD levels less than10 ng/mL were considered severely deficient, levels below 20 ng/mL were considered deficient, and levels of 20 ng/mL or greater were considered adequate. Patients’ samples were collected upon initial presentation, except 29 participants whose samples were taken at antiviral therapy initiation.

The mean 25OHD concentration for the cohort was 14.4 ng/mL. Forty-seven percent of participants were considered 25OHD deficient; 34% were severely deficient. 25OHD levels were similar between Caucasians (14.38 ng/mL) and non-Caucasians (14.59 ng/mL) (P=.7).

An inverse correlation was observed between levels of HBV DNA and 25OHD (P=.0003). Multivariate analysis indicated that HBV DNA was strongly predictive of low 25OHD levels (P=.000048), and vice versa (P=.0013). Patients with HBV DNA levels less than 2,000 IU/mL had 25OHD concentrations of 17 ng/mL; those with 2,000 IU/mL or higher had concentrations of 11 ng/mL (P<.00001 for difference). Participants who tested positive for hepatitis B e antigen (HBeAg; n=26) had significantly lower 25OHD levels than HBeAg-negative participants (P=.0013); this association was significant only under univariate analysis.

Investigators also noted fluctuations in HBV DNA and 25OHD levels according to season. Significantly lower HBV DNA levels were observed among samples taken during spring or summer than in autumn or winter (P=.01).

“The present study demonstrates a profound association between higher levels of HBV replication and low [25OHD] serum levels in chronic hepatitis B patients,” the researchers wrote. “At least in patients without advanced liver disease … HBV DNA viral load appears to be the strongest determinant of low [25OHD] serum levels. … Future studies to evaluate a therapeutic value of vitamin D and its analogs in HBV infection may be justified.”

Got HBV? Adding Vitamin D to Your Diet

13 Comments

Do you have hepatitis B, and are you considering adding vitamin D to your diet?  Adding vitamin D seems to be a win-win for those with liver disease since it is a potent immune modulator, appears to aid in the prevention of cancer, and other potentially related disorders such as NAFLD, along with Type I and II Diabetes, glucose intolerance and metabolic syndrome.  Before you make any big additions, be sure to talk to your doctor or liver specialist to ensure it’s safe for you with your current health status.

Vitamin D is a fat soluble vitamin (needs a little fat to digest), versus a water soluble vitamin, that is ultimately stored in the liver.  There are pros and cons to this.  Fat soluble vitamins are not necessarily needed on a daily basis as they are stored in fatty tissues and in the liver making it available for longer periods of time.  Vitamin D is specifically stored in the liver. Unlike water soluble vitamins, excesses are not excreted through urine on a daily basis. That makes the balance a little trickier because you don’t want vitamin D accumulating in the liver and causing toxicity. Symptoms of vitamin D deficiency include osteomalacia, or softening of the bones, or perhaps less obvious bone pain and muscle weakness. Symptoms of vitamin D toxicity may include decreased appetite, nausea,vomiting, excess calcium blood levels or an accumulation of calcium in soft tissues. Too much of a good thing is NOT good for you!

Current guidelines for vitamin D intake are 600 IU or 15 mcg per day. (See table for age specific info). Natural sources of vitamin D in foods (vitamin D2, or ergocalciferol) are hard to come by, but they are out there.  Mega sources include fatty fish like salmon, mackerel, and tuna.  Cod liver oil is an excellent source, which is probably why we see old movies with mom spooning cod liver oil into the mouths of young children! In the U.S. many dairy products, and others such as cereals, or orange juice are fortified with vitamin D and other vitamins. (There’s a great reason for the fortification of dairy with vitamin D – absorption is enhanced in the presence of calcium.) It is also found in smaller amounts in egg yolks. Naturally all of this needs to be balanced with the concerns of farm raised fish and possible exposure to PCBs, or mercury levels found in tuna, pollution of our oceans, raising your cholesterol levels due to focusing on the yolks, possible toxic levels of vitamin A with cod liver oil  (in Western countries where foods are fortified with vitamin A), or simply the bad, fishy taste associated with cod-liver oil. It’s a tough balance, but it’s important to work through some of the risks versus benefits in your own mind.

Sunshine is another readily available source of vitamin D (vitamin D3, cholecalciferol), but you need to be sure to balance it with the risk of over-exposure to the sun’s rays. And of course in the north, during the winter months, it may be difficult to get adequate sunshine to boost your vitamin D levels. You can get adequate sun exposure with 10-15 minutes in the sun, 3-5 times per week, with the exposure of face and arms. Naturally this will vary based on the sun’s intensity, how much skin is exposed and each individual’s skin tone, since the amount of necessary sun increases with the amount of melanin (pigment) in the skin.  Just to confuse matters, a recent study shows a possible link of higher levels of vitamin D to non-melanoma skin cancer, even though higher levels are thought to reduce the risk of basal cell cancer. Clearly more studies need to be done, but until that time, just keep reminding yourself that balance is important.

Sometimes it’s tough to get adequate vitamin D levels from natural sources such as food and sunshine, so there is the option for vitamin D supplements. This is where my anxiety levels intensify. Bad enough I have to worry about my food sources – PCBs from farm raised fish and such things, but now I have to choose a supplement – perhaps cod liver oil in a liquid or capsule that I can take daily.  Will it be in a form that is able to be absorbed?  (There’s a debate on the true benefit of cod liver oil once it is processed.  The same argument might apply to many available supplements.) How will I know this?  Will I break the bank trying to purchase these supplements?  I started to do the research on vitamin D supplementation, but like so many supplements, it’s very complex.  I always feel like I’m being sold. Using supplements is a personal thing. My personal preference would be to get my vitamin D through the foods I eat, and a short duration of sunshine.  However, I currently have adequate levels of vitamin D, so whatever I’m doing seems to be adequate.  That’s the key: tailoring your decisions based on you, your family history, or ethnicity and things you might be prone to such as a vitamin D deficiency, or other issues.

Please don’t forget to talk to your PCP and your liver specialist before drastically changing your vitamin D intake.  This is especially important if you are currently undergoing treatment for HBV.  Your doctor may wish to get a general baseline of your vitamin D levels, and continue to monitor them if there are problems.  Your doctor may be uncomfortable recommending a specific supplement since there is little or no regulation. Heed her advice before moving forward, and if you choose the supplementation route, be sure to do your homework to get the best quality product that is readily absorbable, without causing toxicity.

Hepatitis B and Vitamin D

16 Comments

Vitamin D is essential for everyone, but how might vitamin D help those living with HBV? Vitamin D is especially important for children and older adults, as it aids in the body’s absorption and regulation of calcium and phosphorus, which helps form and maintain healthy bones and teeth.  Vitamin D is also a potent immune modulator, and aids in the prevention of hypertension, and cancer. Vitamin D levels appear to play a critical role in type I and type II diabetes, glucose intolerance, and metabolic disorders.  Studies have also shown a link between low vitamin D levels and NAFLD (Non-alcoholic fatty liver disease), independent of metabolic syndrome, diabetes, or insulin-resistance profile (for those without HBV). The lower the vitamin D level, the higher the risk for NAFLD, or fatty liver disease.  The liver plays such an integral part in digestion, regulation, storage, and removal of toxins – the list goes on.  You can’t live without it!  As a result, it seems logical that healthy levels of vitamin D would benefit those living with HBV, if adequate vitamin D levels help reduce the risk of NAFLD, metabolic syndrome, etc.

Vitamin D is a potent immune modulator.  It has been on the radar for the prevention and treatment of infectious diseases for years. If you are being treated for HBV, you may want to discuss the potential benefits of adding vitamin D to your current therapy.  It has been shown to benefit hepatitis C patients undergoing treatment.  There is currently a clinical trial in Israel looking into the possible benefits of adding vitamin D supplementation to hepatitis B patients undergoing Peginterferon, or treatment with nucleotide analogs.

While researching this blog, I ran across a couple references that mention Fanconi’s Syndrome and vitamin D.  This is interesting since Fanconi’s Syndrome may be acquired as a result of HBV treatment with tenofovir.  Fanconi’s Syndrome and supplementation with vitamin D is also mentioned on the Mayo Clinic site.  The problem is there are no studies that definitively discuss the benefits of vitamin D supplementation for those living with HBV.  I am no doctor, but there seems to be a connection between vitamin D and good liver health.

Start by talking to your doctor or liver specialist about the pros and cons of considering additional vitamin D in your diet. Request that your vitamin D levels be tested so you get a snapshot of your current levels. I had my girls’ levels checked.  They were adequate, but I regretted having them tested during the summer break when they are outside more often. I wonder how this reflects on their levels in the winter when they are rarely outside?  Food for thought.

The 25-hydroxyvitamin D (25(OH) D) blood test is used to measure serum levels of vitamin D. Normal serum levels, indicated by the Institute of Medicine (NIH), are 50 nmol/L (20 ng/mL) or greater.  Low levels are under 30 nmol/L (12 ng/mL).  See detailed charts for age specific requirements. There are all kinds of reasons for inadequate levels of vitamin D, so it is important to follow up with your doctor if your results are out of the normal range.  You may require additional testing.

It is important to maintain a balance and use common sense when considering supplementing your diet with Vitamin D.  Vitamin D is essential, but too much of a good thing can be dangerous to your health. Be sure to keep your doctor in the loop – especially if you are currently undergoing HBV treatment.
