Once diagnosed with Hepatitis C, a little research will eventually
reveal that the current standard treatment is pegylated interferon with
ribavirin. Despite the relatively low rate of success in eliminating
the virus, many may mistakenly believe that it doesn’t matter who
administers the treatment. However, new research demonstrates that it
is well worth the effort to seek out a specialist for monitoring your
therapy.
Successful Treatment
Known as sustained virological response (SVR), successful treatment for
Hepatitis C is described as the inability to detect any of the virus in
the blood six months after stopping therapy. Although it is currently
the only viable option for Hepatitis C, estimates of those attaining
SVR with pegylated interferon and ribavirin treatment vary widely.
Regardless of a study’s country of origin, large trials evaluating
Hepatitis C treatment success have reported SVR rates ranging between
30 and 80 percent. However, close examination of people fighting
Hepatitis C in the real world have led researchers to suspect that the
type of doctor a patient seeks help from significantly impacts SVR
likelihood.
German Study
In an attempt to realize the real world impact of the type of physician
administering Hepatitis C treatment, researchers at the University of
Dusseldorf conducted a landmark retrospective study. At their
outpatient clinics, these German researchers analyzed the records of
patients receiving at least one dose of interferon treatment for
Hepatitis C over a span of seven years.
After analyzing over 300 people receiving Hepatitis C treatment for
the first time, approximately two thirds consulted with an expert
hepatologist on a regular basis while just over one third had their
interferon treatment administered and supervised by a general
practitioner. Even though the characteristics of infection were similar
between those working with a hepatologist and those seeing a general
practitioner, the outcomes of Hepatitis C treatment were significantly
different between the two groups.
Right after interferon treatment, elimination of the Hepatitis C virus was more likely for those seeing a hepatologist:
· A viral load of zero was evident in 74 percent of those seeing a hepatologist.
· A viral load of zero was evident in 48 percent of those seeing a general practitioner.
At the six-month mark when SVR is measured, those seeing a hepatologist continued to have a definite advantage:
· SVR was attained by 66 percent of those seeing a hepatologist.
· SVR was attained by 34 percent of those seeing a general practitioner.
When broken down even more, those with genotypes 1 and 4 and those
with advanced liver damage specifically benefited from expert care:
· For study participants infected with genotype 1 or 4, SVR was attained by 61 percent of those seeing a hepatologist.
· For study participants infected with genotype 1 or 4, SVR was attained by 27 percent of those seeing a general practitioner.
· For study participants with advanced liver damage, SVR was attained by 69 percent of those seeing a hepatologist.
· For study participants with advanced liver damage, SVR was attained by 25 percent of those seeing a general practitioner.
These results led the German authors to conclude “Patients
with…genotypes 1 and 4 or with advanced liver damage benefit from HCV
therapy supervision by a specialist, probably because of less frequent
treatment interruptions or dose reductions.”
What Is An Expert?
A hepatologist is a physician who has obtained additional, specialized
training in liver diseases. Initially, all hepatologists are trained in
general internal medicine (adult medicine) or pediatrics (children’s
medicine). Some pursue additional training in gastroenterology (which
includes digestive disorders involving the esophagus, stomach, small
and large intestines, pancreas, gallbladder and liver). However, to be
a hepatologist, a fellowship focusing solely on the liver is typically
mandated. Even though a hepatologist is the most qualified type of
doctor to treat liver disease, there is currently no separate board
certification examination in this highly specialized field.
The field of hepatology is a rapidly changing, emerging field. Even
though the standard of care for Hepatitis C has been interferon-based
treatment for many years, there are many factors involved in its
administration. Hepatologists are up-to-date on the latest research and
discoveries for treatment modifications, length of treatment, dosage
adjustments, side effect management and all of the other details
related to Hepatitis C treatment.
Although most people are comfortable with their general practitioner
– and they may have been the physician who originally detected their
infection – an expert may be more qualified to administer Hepatitis C
treatment. Especially important for people who have genotypes 1 or 4,
or who already have advanced liver disease, the chance of achieving SVR
is much higher when an expert liver specialist manages treatment.
