ChrisKHBF is pleased to connect our blog readers to Christine Kukka’s monthly HBV Journal Review that she writes for the HBV Advocate. The journal presents the
 latest in hepatitis B research, treatment, and prevention from recent academic and medical journals. This month, the following topics are explored:

  • Belatedly, National Panel Recommends Screening At-Risk Patients for Hepatitis B
  • Genotypes and Mutations Define the Course of Hepatitis B Infection
  • Older Patients Who Lose HBeAg After Treatment May Relapse
  • Tenofovir Proves Ineffective in Patient with Multiple Drug Resistance
  • Nearly All HBeAg-Negative Patients Relapse After Antiviral Treatment Stops
  • Studies Find Hepatitis Infection Does Not Increase Pancreatic Cancer Risk
  • Screening Pregnant Women for High Viral Loads Is Cost Effective
  • Hepatitis B Appears to Impede Fertility
  • Despite Low Viral Load, Infected People Can Still Infect Family Members

Belatedly, National Panel Recommends Screening At-Risk Patients for Hepatitis B

Ten years after it recommended against screening the “general population” for hepatitis B, an independent national task force that creates prevention guidelines for primary care providers has finally recognized that certain high risk groups in the U.S. should be screened for hepatitis B.

Their recommendations, recently published in the Annals of Internal Medicine, come after numerous studies faulted primary care providers for failing to screen patients for hepatitis B and missing opportunities to treat patients for liver disease and immunize family members against hepatitis B virus (HBV) infections.

Other health care organizations, including the U.S. Centers for Disease Control and Prevention (CDC), the Institute of Medicine, and the American Association for the Study of Liver Disease, have been recommending for years that primary care doctors screen high-risk patients for hepatitis B, which has infected up to 2.2 million Americans.

The U.S. Preventive Services Task Force (USPSTF) recently issued clinical guidelines recommending that doctors screen the following patients for hepatitis B:

  • People from countries that have hepatitis B rates exceeding 2% (which includes Asia, Africa, Central Europe and parts of Central and South America).
  • U.S.-born people whose parents immigrated from countries with high rates of HBV infection.
  • HIV-positive people, injecting drug users, men who have sex with men, and
  • Household contacts of people infected with HBV.

The task force’s guidelines suggest that because an effective vaccine to protect against the infection and effective treatments for hepatitis B are now available, they decided to issue these recommendations. However, both the vaccine and effective treatments have been available for more than a decade.

“In the 2004 recommendation, the USPSTF focused only on the general population,” the authors wrote in the recommendations. “In the current recommendation, the USPSTF focused on high-risk populations as it considered new evidence on the benefits and harms of antiviral treatment, the benefits of education or behavior change counseling, and the association between improvements in intermediate and clinical outcomes after antiviral treatment.” The task force noted that it, “…found inadequate evidence that education or behavior change counseling reduces disease transmission.”

Genotypes and Mutations Define the Course of Hepatitis B Infection
Researchers are increasingly finding that HBV genotypes or strains—and the mutations that they generate—can determine the severity of a patient’s infection.

Each of the world’s 10 genotypes and their mutations have different characteristics that can increase risk of cirrhosis and liver cancer, determine whether an infection becomes chronic, and basically determine a patient’s destiny, according to a recent study, published in the May issue of the World Journal of Hepatology …

Study Finds Only 21% of Hepatitis B Patients Are Treated Correctly

A new study, examining how well San Francisco primary care providers care for their patients infected with the hepatitis B virus (HBV), finds most fail to screen them for liver cancer or regularly evaluate their viral load or hepatitis B “e” antigen (HBeAg) status, though medical guidelines require annual or semi-annual testing.

The study, published in the September 2013 issue of the journal Digestive Diseases and Sciences, surveyed doctors who provide care through a safety net program to many uninsured patients. They were asked how well they thought they followed current medical guidelines, and then patient medical records were analyzed to assess the true quality of care.

Of the 148 doctors surveyed, 79% claimed to follow medical guidelines and monitor patients’ liver health every 6 six 12 months. However, patient medical records covering the last 12 months showed substandard care.

  • • Only 75% of patients had their alanine aminotransferase (ALT) levels, which shows liver damage, tested in the past year.
  • • Only 51% had their viral load (HBV DNA) tested.
  • • Only 51% had been screened for liver cancer (either with an alpha fetoprotein test or some type of liver imaging). This test should be performed annually, and doctors are at risk of medical malpractice if they do not screen patients for cancer.
  • • HBeAg tests were performed in only 29% of patients.
  • • Only 32% of the hepatitis B patients had been immunized against hepatitis A, another guideline requirement, to protect them from another liver infection.

Bottom line, researchers found that only 21% of patients had been monitored properly in compliance with current hepatitis B guidelines. Forty-three percent of doctors were not familiar with medical guidelines for hepatitis B management and only 73% answered all questions about hepatitis B correctly.

There was also a racial bias regarding which HBV-infected patients were screened for hepatitis C and HIV. Doctors tended to test African-American and Latino patients for hepatitis C (48% and 44% respectively) at a higher rate than they tested whites and Asian-American patients (34% and 31%.)

The study suggests that fear of malpractice—more than knowledge of current practice guidelines—may drive doctors to perform the required liver cancer screenings each year. Also, the researchers suggest that hepatitis B public education initiatives, spearheaded by the San Francisco Hepatitis B Free Campaign, may have contributed to better monitoring of Asian-Americans because it raised awareness among the public and their providers.

“These findings highlight the importance of targeted provider education to improve overall care,” for hepatitis B, the researchers from the University of California, San Francisco, suggest.
