Introduction
Hepatitis C virus (HCV) is considered a signifcant public health
problem [1]. It currently infects more than 170 million people
worldwide. Te great majority of patients develop chronic HCV
infection, which can ultimately result in hepatic cirrhosis, failure or
hepatocellular carcinoma, leading to about 350,000 deaths each year
[2,3]. Egypt shows the highest prevalence (15%) of hepatitis C virus
worldwide. It also has the highest predominance of HCV- 4 (67%),
especially subtype 4a (55%). Te history of infection and the disease
progression are infuenced by various factors such as level of HCV
viremia, age at the onset of infection, sex, co-infection with hepatitis B
virus and duration of infection [4].
Sofosbuvir (Sovaldi
®
) Sofosbuvir is a new antiviral candidate against
multiple Hepatitis C virus genotypes [1]. It is a nucleotide analogue that is
a potent inhibitor of NS5B polymerase in HCV. NS5B is a non-structural
protein which is essential for viral RNA replication and has been a valuable
target for many directly acting antiviral agents [3]. Numerous in vitro
studies show promising results against all genotypes of HCV. Sovaldi
®
is approved by the Food and Drug Administration for the treatment of
chronic HCV infection [1]. It has shown high efcacy in combination
with other drugs in antiviral treatment regimen. Tis drug is of special
interest among directly acting antiviral drugs due to its high potency, oral
administration, low side efects and high barrier to resistance [3].
Liver is the main organ responsible for the detoxifcation processes
in our bodies and it is likely to be injured regularly by ingested toxins.
Te regenerative properties of the liver are in fact logical adaptation
procedures carried out by organisms, for which liver damage depends
on for recovery [5]. Liver regeneration is achieved through a complex
network consisting of liver cells (hepatocytes, Kupfer cells, hepatic
stellate cells, sinusoidal endothelial cells and stem cells); and extrahepatic
organs such as thyroid gland, pancrease, adrenal gland, duodenum and
autonomous nervous system [6]. Liver regeneration is achieved by both
cell proliferation and cell growth of hepatocytes, which are induced
via stimulations of cytokines and growth factors. Restoration of liver
volume depends mainly on hepatocyte proliferation, which includes
initiation, proliferation and termination phases [5,6].
In the absence of reliable liver-protective drugs in the modern
medicine, a variety of medicinal preparations are recommended
for the treatment of liver disorders [7]. Herbal drugs contain a wide
number of phytochemicals that occur naturally in the plants, and
may have potential protective or disease preventive properties [8-
12]. Tus, studying the potential biological activity of crude drugs
can result in the discovery of novel lead drugs for certain diseases and
can lead to combining the strength of traditional application of herbal
therapy with the modern concept of standardization, evidence-based
pharmacological evaluation and controlled clinical trials in order to
support clinical efcacy [13,14].
Hepatoprotective Plants
Some fruits (grapefruit, grapes, cranberries and cactus pear fruit);
plants such as chamomile and resin (propolis), which are consumed
frequently by humans, in addition to some phytochemicals extracted from
fruits, plants, algae, and yeasts have been evaluated in diferent models
of hepatotoxicity and demonstrated hepatoprotective capacity [15]. A
number of hepatoprotective plants have been tested in hepatotoxicity
experimental models, which are ofen supported by histopathological
examination of liver, thus provide an insight to the use of these plants
against liver disorders in addition to regeneration of damaged hepatic
tissues [16]. Some examples of these plants are listed below.
Glycyrrhiza glabra (Leguminosae)
Glycyrrhizic acid is a triterpene glycoside found in the roots of
liquorice (Glycyrrhiza glabra). It possesses a variety of pharmacological
Abstract
Objective: Hepatitis C virus is a major health burden. It has infected millions of people worldwide with the
highest prevalence in Egypt. Sofosbuvir (Sovaldi
®
) has been recently approved for treating chronic hepatitis C virus
infections. Herbal medicine has been searched for centuries for the remedy of liver diseases.
Key ings: Plants contain phytochemicals that proved to demonstrate hepatoprotective activity in vitro in
various hepatotoxic models. Herbal drugs also proved effcacy in many clinical trials in reducing the viral load and
improving the clinical manifestations in patients suffering hepatitis C virus.
Conclusions: A hypothesis is postulated for the possibility of the use of a herbal mixture of plants, which are
known for their hepatoprotective activity, in a combination therapy with directly acting antiviral drugs such as Sovaldi
®
to help regenerate the liver, improve the clinical condition and reduce both the cost and side effects for hepatitis C
virus patients.
