Statins May Prevent Liver Cancer For Those With HBV

Good news for those with chronic hepatitis B that are taking cholesterol-lowering statins.  Results published in Jan. 23 Journal of Clinical Oncology show statins may actually lower the risk of liver cancer for those living with chronic HBV in a dose dependent manner. The study monitored 33,413 hepatitis B patients for hepatocellular carcinoma (HCC) between 1997 and 2008 and tracked the number of HCC cases since 1999.

These are important findings because chronic hepatitis B significantly increases the risk of liver cancer, which causes 80% of primary liver cancers (HCC) worldwide. In the U.S., HCC is the second deadliest cancer with a five year survival rate of less than 10%. Those with chronic HBV are 100 times more likely to develop liver cancer than those without HBV. There are a number of contributing risk factors such as age, gender, ethnic background, family history, smoking history, and extent of liver damage. Despite the known risks, it is impossible to predict without regular liver cancer screening.  Be sure to discuss the guidelines for liver cancer screening with your doctor, as there are specific risk factors that may make monitoring sooner and more frequent, important.  Make liver cancer screening part of your bi-annual or annual monitoring of your HBV and liver health.

So, how do statins reduce the risk of liver cancer for those with Chronic HBV?  The mechanism has not been determined and will require further study.  Statins may reduce the risk of HCC, but it is important to carefully discuss the use of statins with your liver specialist and other treating physicians. Monitoring of your liver enzymes while taking statins is important for those without HBV, but it is even more critical if you have HBV.  Start with a baseline of your liver enzymes (ALT/AST) before beginning statin use, followed by testing at 6 and 12 week intervals.  You want to ensure your ALT/AST levels do not increase by more than three times the upper limits of normal.  Any spikes in your ALT/AST levels will likely occur in the first three months of statin use.  Elevated levels may require a discontinuation of one statin and a simple switch to another.  With the help of your treating physician(s) you will determine what is best for your unique situation to ensure the benefits of statin use outweigh the risks.

And if you are taking a daily statin, don’t forget the importance of eating a well-balanced diet. Sitting down to a big-ole cowboy steak with your statin is probably not what the doctor had in mind when he prescribed cholesterol-lowering medication!

Living With HBV and Drinking Coffee

The pros and cons of drinking coffee have been wildly debated for years.  However, for those with Hepatitis B and other liver diseases, the addition of a couple of cups of coffee per day to slow down the progression of liver disease, along with decreasing the risk of diabetes and heart disease just makes sense.

Dr. Melissa Palmer was a guest speaker at a previous Hepatitis B Foundation patient conference. The information from her presentation had all sorts of nutritional nuggets for those with HBV (Check out Dr. Palmer on podcast if you would like to have a listen!) She stated, based on studies, that coffee and caffeine intake has been associated with improvements in liver ALT and AST levels.  There also seems to be a correlation between increased coffee consumption and warding off cirrhosis and HCC.

Just recently there are was an article that discussed the benefits of coffee for those patients with HCV, undergoing treatment with pegylated interferon (PEG) and ribavirin therapy.  It claimed that drinking three or more cups of coffee a day not only reduced some of the difficult side-effects associated with treatment of PEG, but it also increased the treatment success.  However, like so many of these coffee studies, it was a small study and had to be adjusted for other factors.

We all know that HBV and HCV are very different viral infections, but you have to wonder if any of the benefits of coffee that is seen in those being treated for HCV can be extrapolated to include those with HBV being treated with Pegylated interferon or antivirals.  Dr. Palmer did mention that coffee did seem to have a greater impact on those with hepatitis C, although I have no idea why.

Regardless, if you’re living with HBV, you have to think about the pros and cons of adding coffee to your daily list.  Since all studies seem to show an increased number of cups of coffee having a more positive impact on preventing liver disease progression, or warding off cirrhosis or potentially reducing PEG side effects or benefiting treatment, you have to consider just how much caffeine you can take.  It does not appear that caffeine is the only factor involved, but rather the coffee bean itself and associated antioxidant features.  This seems to be the case because tea, despite all of its benefits, does not appear to have the same protective effect on the liver.

What about decaffeinated coffee?  I kept looking to see if it was specifically referenced, but I haven’t seen it. However, during the decaffeinating process, much of the bean is lost, and it may be treated with a chemical solvent, both which might nix the positive benefits.  If you’re going to give decaffeinated coffee a try, consider a coffee with a more natural decaffeinating process. Personally, I’d have a tough time balancing the jitters and racing heart rate associated with drinking more than a cup or two of high-test coffee a day, but we’re all individuals.  If you can drink coffee and sleep well at night, it seems like it can’t hurt your liver health to add a few cups to your daily regimen.

Participating in HBV Clinical Trials

Have you considered participating in hepatitis B clinical trial?   A clinical trial can be a great opportunity to take advantage of the latest advancements in HBV treatment and monitoring, typically without expense to the patient.  It can open doors and provide an opportunity to interact with liver specialists on the leading edge of treating HBV.  There are numerous clinical trials for hepatitis B offered all around the world, from adult to pediatric patient populations.

There are three testing phases that drugs go through before they are approved for use for by the FDA.  A fourth phase examines long-term use.  This is a rigorous process, costs hundreds of millions of dollars and takes 12-15 years before a drug is finally approved. Check out the animated Drug Discovery Time Line to get a better appreciation for the process.

A major advantage of participating in a clinical trial is that expensive treating medications, clinical monitoring, and lab work are typically provided without expense to the patient, and the patient is monitored throughout the process by experienced, participating liver specialists.

The next thing to consider is whether or not you are eligible for a particular trial.  There are various inclusion/exclusion criterion.  Some trials or studies are looking for patients that are treatment naïve, (patients who have not taken medications for HBV) while others are looking for patients that are treatment experienced, (patients who have taken particular medications for HBV) but may have failed on one treatment protocol, and might need “rescue therapy,” such as an antiviral to replace a previous antiviral where a resistance to the drug has occurred based on a viral mutation.  It varies with trial.

Other studies may be looking for candidates based on HBe status (positive or negative), degree of liver damage, or ALT or HBV DNA levels over a particular time period. You must first qualify before you consider participation in a trial or study, so be sure to check the qualifying criterion, and discuss with your doctor.

Naturally, each candidate will need to weigh the risks versus the benefits of receiving an experimental drug. Discuss the pros and cons with your doctor. Do you really need treatment for your HBV at this time? What are the possible short and long term side effects? Do you think you can manage them? You know your body best. What about the logistics?  Is there a need for frequent lab work?  Does it need to be done on site, or can blood be drawn at a local lab?  What happens when the trial is complete?  This is especially important when considering antivirals. Will you need to remain on the medication when the trial is complete?  Will you be financially responsible, and if so can you afford it?  Will participating in a trial exclude you from future trials?  What about resistance and cross resistance to future drugs? These are a few of the questions for which you need to think long and hard, and of course discuss them with your liver doctor and the participating specialist.

It also doesn’t hurt to ask other patients on HBV internet support groups.  You might well find someone with personal experience with the drug, keeping in mind that everyone responds somewhat uniquely to the same drug therapy. I have found these forums extremely helpful when considering a new drug.

The Hepatitis B Foundation is committed to maintaining monthly, updated clinical trial data available to friends living with HBV on our website.  We do much of the up-front work for you by sorting through the hundreds of trials available via clinicalTrials.gov, a registry of clinical trials.  We divide the data into unique treating situations that might benefit various patients, such as clinical trials for patients that live in the U.S. or internationally pediatrics, coinfected, candidates for liver transplantation, patients struggling with HBV related hepatocellular carcinoma, and HBV reactivation and lymphoma.  Most trials relate to the treatment of HBV, while some are observational studies, long term studies where patients are monitored over time.  Some relate back to treatment studies – durability of treatment or long term effects, while others study patients with HBV, and identifying factors that may cause the disease to activate or worsen, and are monitored via annual or bi-annual blood work and annual visits.  It varies with the trial.

So if you have HBV, consider your status. If you are a candidate for treatment, consider existing, approved treatments vs. participation in an HBV clinical trial. It’s up to you and your doctor to determine if a clinical trial is a good fit.
