Hepatitis B Precautions for People Living with Diabetes

 

March 27th is Diabetes Alert Day!

Diabetes is a chronic condition that is characterized by high glucose (or sugar) levels in the blood. It usually occurs when a person cannot produce enough insulin, a hormone that controls blood sugar levels. According to the World Health Organization (WHO), global prevalence of diabetes is on the rise! In 1980, diabetes prevalence in adults over the age of 18 was 4.7%. The number rose to 8.5% in 2014 and continues to increase. In 2015, there was an estimated 1.6 million deaths that were attributed to diabetes.

Like hepatitis B, there have been several studies that show a strong link between type II diabetes and liver cancer. Diabetes and hepatitis B can be a dangerous combination and can work together to increase someone’s risk of developing liver cancer.

Since the hepatitis B virus can be transmitted via blood or other bodily fluids, people living with diabetes are at an increased risk of contracting hepatitis B. In fact, one study found that people living with diabetes between the ages of 23-59 have an approximately two-fold increased risk of hep B infection compared to those without diabetes. According to the Centers for Disease Control and Prevention (CDC), there have been hepatitis B outbreaks in nursing homes, assisted living, and long-term care facilities among people living with diabetes. Some risks for transmission include:

  • Sharing glucose meters between residents without cleaning and disinfecting between uses
  • Lack of proper hand hygiene and failure to wear gloves between fingerstick procedures
  • Using the same fingerstick devices for more than one resident
  • Cross-contamination of clean supplies with contaminated blood glucose monitoring equipment used by home health agencies
  • Sharing injection equipment such as an insulin pen or syringe for more than one person
  • Failure to perform proper sterilization and separating contaminated and clean podiatry equipment
  • Failure to perform proper disinfection between podiatry patients

So, what can you do if you are living with diabetes to prevent hepatitis B transmission?

  • Get tested! A simple three-part blood test will tell you if you have hepatitis B, were exposed, or are protected.
  • Get vaccinated – If you find that you are not protected or if you have not finished your hepatitis B vaccine series. The CDC and Advisory Committee on Immunization Practices (ACIP) recommend that adults between 19-59 years of age living with diabetes get vaccinated to protect against hepatitis B. Those 60-years-old or older should ask their doctor about the vaccine before getting it.
  • Do not share your diabetes care equipment to prevent exposure!

Liver Cancer, Living with Hepatitis B

More on Metformin and Statins: Drugs Approved by the FDA for Other Purposes That May Prevent Liver Cancer

1 Comment

From HBF’s expert Guest Blogger, Dr. Thomas London…

In an earlier blog, I pointed out that the available drugs to treat or prevent primary liver cancer (hepatocellular carcinoma, HCC) have been disappointing.  I noted that there may be drugs used for other purposes that may work against HCC.  The most promising of these was an old drug called metformin that has been used to treat type II diabetes for 17 years.  Now a new study on metformin provides the most intriguing results yet.

At the 2012 Digestive Disease Week meeting in San Diego, an enormous study from Taiwan was reported that encompassed almost all of Taiwan’s 23 million people. (I am indebted to Christine Frangou for her excellent report in Gastroenterology and Endoscopy News and have quoted from it extensively.) The investigators used the Taiwan National Insurance Database to identify all cases of HCC diagnosed from 1997 to 2008. There were 97,430 patients with HCC (most of whom would have had chronic hepatitis B). They were compared with 200,000 controls matched to the HCC cases by age, gender, and date of first physician visit.  Using the same database they linked all patients with diabetes and their treatment methods to patients with and without HCC.

From this they were able to show that patients with diabetes had a 2.3-fold increased risk of developing HCC.  In those patients who were taking metformin, however, HCC occurred about 20% less often than in those who were not treated with metformin. Furthermore, the longer patients took metformin, the lower their risk of HCC; about 7% lower for each year that they took the drug.

This study is not the final answer.  We don’t know why some diabetic patients were treated with metformin and some were not.  It is possible that the patients who did not take metformin had some unknown liver abnormality and were deliberately not treated with metformin.  Nevertheless, anti-tumor effects of metformin in experimental animals and in cell culture systems continue to be reported.  I will keep my eye out for more research on metformin and HCC and report it as it hits the medical press.

Statins are another group of drugs that are in common use. They were first approved by the FDA in 1987 to lower serum cholesterol levels and thereby prevent heart disease.  Statins inhibit an enzyme in the liver used to make cholesterol.  Several isolated reports suggested that statins might also help prevent HCC.  This month investigators at the Mayo Clinic in Rochester, Minnesota reported a meta-analysis (a statistical method to combine results from different studies) of all the reports in the medical literature of new cases (incidence) of HCC and exposure to statin therapy.  Ten studies reporting a total of 4,928 HCC cases in 1,459,417 patients were analyzed.  Overall, patients who were treated with statins had a 40% lower risk of developing HCC than those who were untreated.  The results varied from population to population. Asian populations which were more likely to also have chronic hepatitis B, had a 50% lower risk of developing HCC, while western populations had about a 30% lower risk.

At this time we do not know what the mechanism of a preventative effect of statins on HCC might be.  Nor do we know whether statins might have been withheld from patients with high cholesterol levels because they had a liver abnormality. It is likely, however, that more information on these issues will become available in the near future.  When that happens I will report it to you.

 

Hepatitis B Prevention

ACIP Recommends HBV Vaccine for those with Diabetes

1 Comment

What’s new in the world of HBV lately?  Perhaps the biggest HBV story over the last week is the Advisory Committee on Immunization Practices (ACIP) strong recommendation for those with diabetes under the age of 60 years to be vaccinated against HBV.  Diabetics under the age of 60 have twice risk of acquiring HBV than those without. The recommendations for vaccination apply to those with type 1 or type 2 diabetes. The sooner those living with diabetes are vaccinated, the better.

Those living in long-term care facilities that require assisted glucose monitoring are also at greater risk for HBV.  This increased risk occurs during the monitoring process, where the accidental re-use of lancets and needles may occur from one patient to another. It is imperative that infection control practices be strictly followed in this environment to prevent small, HBV outbreaks among the elderly in long-term care facilities. HBV vaccination is not recommended for the majority of those over age 60 because the HBV vaccine is not as effective in the frail and elderly population. The earlier in life one is vaccinated against HBV, the better.

Speak up and make sure your loved-one living in long term care and living with diabetes and/or HBV has a personal glucose meter, or that proper infection control practices are being followed at their long-term care facility.

Diabetes and hepatitis B are each challenging chronic conditions to manage alone, but in combination, they can be very complicated. If you are a diabetic with HBV, it is essential that you follow the recommendations provided by both treating physicians (for both diabetes and HBV), and that both are in synch with one another.  It comes down to you faithfully adhering to all medications prescribed, strict monitoring of both your diabetes and your HBV status as dictated by your doctor(s), and following all recommended lifestyle changes.  Be sure to keep your doctor apprised on new issues that may come up as a diabetic with HBV.

If you have HBV, and do not have diabetes, but have a family history of diabetes, take precautions now. Talk to your doctor and be sure to monitor your blood pressure, cholesterol, and weight.  Maintain a healthy weight through diet and exercise.  Know that risk of type 2 diabetes increases with age, (greater than 45) and that your ethnic background may also be a risk factor. This would include Hispanics, African-Americans, Native Americans, and Asians.
