Introduction

Hepatitis C virus (HCV) attacks the liver and leads an inflammation [1]. 3% of the world’s population liver injure is infected with HCV as mentioned in recent WHO report; which was estimated that more than 170 million chronic carriers are developing liver cirrhosis and/or liver cancer [2].

HCV symptoms rarely occur in infected population; as dark urine, yellow tinged skin, fever and abdominal pain are occurring. 75% to 85% of chronic infection patients has no symptoms, hence leads to liver disease and cirrhosis [3,4] while cirrhotic patients will be developing other complications as liver failure, liver cancer [5].

Magic fruit (Ziziphus jujube) strengthens the liver and is used by Chinese practitioners for hepatitis and cirrhosis. It is stimulating the immune system [6]. The magic fruit (Ziziphus jujube) or the Chinese date is a member of Rhamnaceae family. It helps in many of vital activities and functions such as weight gain, antiallergenic, improving stamina and strength, mildly sedating, improving of liver function, and helping to efficiently get the energy from food and giving energy [7]. Ziziphus jujube is one of such medicinal plants used for curing liver ailments, insomnia, anemia, diarrhea, diabetic complications and cancer [8]. The practice of application of medicinal plants for relief from many illness dates back to ancient times, Ziziphus Jujuba Mill. (Z. Jujuba ) or the jujube, a herbal plant used in traditional medicine.

Honey is a natural product that produced in honey bees. In a complex process, they collect the nectar from different flower mixing with their salivary and enzymatic secretion [9]. Honey is well known as an antifungal, antibacterial and antioxidant behavior because of phenolic compound [10]. The main constituents of honey are 50% fructose and 44% glucose [11] which gives the sweety flavor, while the remaining constituents of honey, chrysin, pinobanksin, catalase, pincocembrin and vitamin C which acting as an antioxidant [12].

Materials and Methods

Patients

The present study has been conducted on a total of 50 patients, all with chronic hepatitis C (The male number was 35 while the female was 15; The median age was 45 years) taken from the outpatient clinics of the NCI-Cairo University in Egypt. Blood samples were obtained during the time from July 2014 to January 2015. Treatment the patients who have (virus C) by taken them 4 g from Magic fruit and 1 g from Honey bee 3 times daily for three months. Blood samples were collected from patients before and after treatment. Serum samples were permitted to clot for 30 min at 37°C [13,14]. Then, they were centrifuged at 3000 RPM for 10 min. The sera were collected and divided to several aliquots and were stored at -20°C until starting our tests. According to Giardina's recommendation, the AFU activity levels were done within 30 days after collection [15].

HCV-test, HCV PCR analysis, FoxP3, and T-regulatory cell (CD4, CD25) in HCV patients have been performed before and after treatment.

HCV-PCR levels were quantitatively determined by instrument of Applied Biosystems (AB) step one real-time PCR system (Singapore), while CD4, CD25 were analyzed by instrument of Flow Cytometery NAVIOS Flow Cytometery. Beckman Coulter (USA). The biochemical parameters as CBC, Liver function tests, kidney function tests were done by integrated automation in clinical laboratories in NCI.

Statistical Analysis

Data were expressed as Mean ± SD. The SPSS program version 15 was used in analysis. One-way analysis of variance (ANOVA) followed by Duncan post hoc test and/or t-test were used in analysis. Chi-square test was used for categorical data. Pearson correlation coefficient was used to study correlations. The percent change was calculated as (values after treatment - values before treatment)/values before treatment × 100, and tabulated as absolute values. P-values less than 0.05 were significant.

Results

Study population

Our study was done on 50 HCV patients from the outpatient clinics at the NCI, Egypt in the period between 2014-2015. They included 35 males and 15 females (66% / 34%). The age range was between 23 and 65 years with a median of 45 years.

Effect of treatment on HCV RNA/PCR (quantitative)

The median PCR was 0.53 × 106 before treatment, a value decreased to 0.12 × 106 after treatment with a percent reduction of 63.94 ± 27.51% (Table 1).

Correlation between PCR, human Fox P3 and CD4CD25 versus the traditional biochemical parameters before and after treatment

Figures 1A, 1B and 1C clarify the correlation between the traditional different biochemical parameters versus PCR, Fox P3 and CD4 CD25 values. Non-significant correlation was detected. While, Figures 2A, 2B and 2C clarify the correlation between the traditional different biochemical parameters after treatment. For PCR, positive significant correlation with uric acid (r=0.299, p<0.05) and negative significant correlation with bilirubin (r=- 0.328, p<0.05) were detected. For human Fox p3 expression, negative significant correlation with creatinine (r=-0.332, p<0.05) and positive significant correlation with ALT (r=0.289, p<0.05) were detected. For CD4 CD25 expression, two negative significant correlations could be detected; with ALP (r=- 0.330, p<0.05) and Hb (r=-0.331, p<0.05), respectively.

Figure 2: The correlation between parameters after treatment.

We observed that; there are correlations between PCR, Fox P3 and CD4 CD25 before and after treatment. There is positive correlation for PCR and Fox P3 before treatment (R=0.377, P<0.01), while a negative correlation was observed between PCR before treatment and CD4 CD25 after treatment (R=-0.359, P, 0.01).

Discussion

The researchers were emphasized a strong association of cirrhosis and HCC due to chronic viral hepatitis. Although the use of surgery, chemotherapy and radiotherapy have led to increasing the survival rates for patients with hepatocellular carcinoma, there are still problems of the marked side effects of the previously mentioned treatments in addition to cancer metastasis that sometimes occurs among those patients. Most cases of HCV infection are asymptomatic and clinical presentation is mild. Resolution of the infection occurs 3-4 months after, 70% of cases do not resolve but progress to chronic hepatitis [16].

Saeed in 1991 was the first to report in Saudi Arabia the very high incidence of HCV-Ab among Egyptian blood donors, which was 19.5%. Darwish in 18 reported that the incidence was 15% among healthy blood donors. Yet, Kamel in 1992 reported that the incidence is 6% among health care workers. The prevalence of HCV in Egyptian blood donors was reported to be the highest among the world [17-20].

Magic Fruit (Ziziphus jujube): In the last few decades there has been an exponential growth in the field of Herbal medicine [21]. Our result elucidates the protective ability of Z. jujube against hepatic injury and chronic inflammation that was confirmed in previous study [22].

Z. jujube showed significant protection against CCl4 intoxicated HepG2 cell lines by means of increased cell viability and decreased LDH levels compared to control group. It was reported for anticancer, anxiolytic, anti-complementary and hypoglycemic activities [23-26]. Jujuba methanol extraction with different concentrations inhibited the lipid peroxidation and significantly restored the liver function markers (Ast, Alt, Alp, LDH) IN Acute liver damaged) [27].

Previous study demonstrated the role of honey supplementation that is improving the immunological behavior which gives a useful result that prevents hepatic damage which caused by obstruction of the common bile duct.

The present work represents the first trial carried out in Egypt to show the effects of the mixture of magic fruit and honey bee on the hepatocarcinogenesis as well as the level of PCR, T-regulatory cell (CD4, CD25), and Fox P3 gene expression. The results showed the highly significant decrease in (PCR, T-regulatory cell (CD4, CD25), and Fox P3 gene expression) level after treatment by mixture of magic fruit and honey bee. The results also showed that the activation of virus-C has been significantly decreased after treatment by the mixture than before treatment indicating the possibility of using the mixture as an inhibitor the activation of virus-C in patients to be active.

Conclusion

In conclusion, the present work casted some light on the probability of using the mixture of magic fruit and honey bee in the natural therapy of virus C through the activation of immune system and decreasing the level of (PCR, T-regulatory cell (CD4, CD25), and Fox P3 gene expression). Future studies are recommended to examine the possibility of using the mixture in the treatment of other types of cancer.
