Adefovir Dipivoxil plus Chinese Medicine in HBeAg-Positive Chronic Hepatitis B Patients: A Randomized Controlled 48-Week Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients.@*METHODS@#A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented.@*RESULTS@#The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns.@*CONCLUSION@#Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).

Chinese Herbal Medicine Combined with Entecavir for HBeAg Positive Chronic Hepatitis B: Study Protocol for a Multi-Center, Double-Blind Randomized-Controlled Trial / 中国结合医学杂志

<p><b>BACKGROUND</b>The domestic prevalence of chronic hepatitis B (CHB) in China is 7.18% in 2006, imposing great societal healthcare burdens. Nucleot(s)ide analogues (NUCs) anti-hepatitis B virus (HBV) therapies are widely applied despite the relatively low rate of seroconversion and high risk of drug-resistant mutation. More effective treatments for CHB deserve further explorations. Combined therapy of NUCs plus Chinese herbal medicine (CHM) is widely accepted in China, which is recognized as a prospective alternative approach. The study was primarily designed to confirm the hypothesis that Tiaogan-Yipi Granule (, TGYP) or Tiaogan-Jianpi-Jiedu Granule (, TGJPJD) plus entecavir tablet (ETV) was superior over ETV monotherapy in enhancing HBeAg loss rate.</p><p><b>METHODS</b>The study was a nationwide, large-scale, multi-center, double-blind, randomized, placebo-controlled trial with a designed duration of 108 weeks. A total of 16 hospitals and 596 eligible Chinese HBeAg positive CHB patients were enrolled from November 2012 to September 2013 and randomly allocated into 2 groups in 1:1 ratio via central randomization system: experimental group (EG) and control group (CG). Subjects in EG received CM formulae (TGYP or TGJPJD, 50 g per dose, twice daily) plus ETV tablet (or ETV placebo) 0.5 mg per day in the first 24 weeks (stage 1), and CHM granule plus ETV tablet (0.5 mg per day) from week 25 to 108 (stage 2). Subjects in CG received CHM Granule placebo plus ETV tablet (0.5 mg per day) for 108 weeks throughout the trial. The assessments of primary outcomes (HBV serum markers and HBV-DNA) were conducted by a third-party College of American Pathologists (CAP) qualified laboratory. Adverse effects were observed in the hospitals of recruitment.</p><p><b>DISCUSSION</b>The study was designed to compare the curative effect of CM plus ETV and ETV monotherapy in respect of HBeAg loss, which is recognized by the European Association for the Study of the Liver as "a valuable endpoint". We believe this trial could provide a reliable status for patients' "journey" towards durable responses after treatment discontinuation. The trial was registered before recruitment on Chinese Clinical trial registry (No. ChiCTR-TRC-12002784, Version 1.0, 2015/12/23).</p>

Efficacy of early treatment on 52 patients with preneoplastic hepatitis B virus-associated hepatocellular carcinoma by compound Phyllanthus Urinaria L / 中国结合医学杂志

<p><b>OBJECTIVE</b>To observe the change in the number of antibodies of preneoplastic hepatocellular carcinoma (HCC) using early treatment by Compound Phyllanthus Urinaria L. (CPUL) on patients with preneoplastic hepatitis B virus (HBV)-associated HCC.</p><p><b>METHODS</b>A total of 102 cirrhosis patients with regenerative or dysplastic nodules whose sera were tested positive for at least one of these six proteins (five up-regulated genes URG4, URG7, URG11, URG12 and URG19, and one down-regulated gene DRG2) were assigned randomly to two groups using continual random codes by SPSS software. Fifty-two patients were in the treatment group and 50 patients were in the control group. CPUL was used in the treatment group for 3 years, while the control group did not receive any treatment. The changes in HBV-DNA level, number of antibodies, and hepatocarcinogenesis occurred were observed. Patients who did not develop HCC were followed up for another 2 years.</p><p><b>RESULTS</b>HBV-DNA levels decreased ⩾2log in 22.2% (10/45) of patients in the treatment group in contrast to only 5.0% (2/40) of patients in the control group (P=0.0228). The number of antibodies that were tested positive in the treatment group (1.08±1.01) was significantly lower compared with the control group (2.11±1.12) after 24 months of drug treatment (P<0.01). Both the positive rates of anti-URG11 (33/52) and anti-URG19 (31/52) were over 60% at baseline in the two groups, and were decreased to 48.1% (25/52) and 46.2% (24/52) respectively at 36 months of drug treatment, while the rates increased to 68.0% (34/50) and 66.0% (33/50) respectively (P=0.0417, P=0.0436) in the control group. The positive rate of anti-DRG2 was increased to 55.8% (29/52) at 36 months of drug treatment, while in the control group was decreased to 36.0% (18/50, P=0.0452). Among the 102 patients who developed HCC, 2 were in the treatment group and 9 were in the control group, meaning that a significant difference between the two groups (P=0.0212). In 11 patients who developed HCC, anti-URG11 and anti-URG19 were always positive, while anti-DRG2 was negative. Patients newly developing HCC were 6 (20.0%) in the control group, and only one (2.5%) in the treatment group (P=0.0441) during 2-year follow-up after the end of the treatment.</p><p><b>CONCLUSIONS</b>Anti-URG11, anti-URG19 and anti-DRG2 could be used as early markers in the prediction of the therapeutic efficacy of CPUL in treating preneoplastic HCC. CPUL is useful in preventing or delaying the development of HBV-associated cirrhosis to HCC.</p>

At the end of the 3-year follow-up, the medians of histopathological <inflammation grading and fibrosis staging declined to a lower rank, and the effect on inflammation was superior in the treatment group to the control group shown by non-parameters Wilcoxon paired symbols test ( Z=2.761,P=0.006).</p><p><b>CONCLUSION</b>Combined therapy of Tongdan Decoction and UDCA showed a better therapeutic effect: than UDCA monotherapy on PBC, especially in improving immunological indices and histopathological hepatic changes.</p>

Combined therapy of shehuang paste and colonic dialysis with Chinese medicines for treatment of refractory cirrhotic ascites complicated with azotemia / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the clinical efficacy of combined therapy of Shehuang Paste (SHP) with colonic dialysis in treating patients with refractory cirrhotic ascites complicated with azotemia.</p><p><b>METHODS</b>Adopting a multi-centered, randomized, double blinded and 1:1 parallel controlled trial, 120 patients were equally randomized into 2 groups, the control group was treated by conventional basic therapy (umbilical application of placebo paste and colonic dialysis with normal saline), and the treatment group by, besides the same basic therapy, umbilical application of SHP once a day and colonic dialysis with herbal medicine once every other day. The course was 1 month for both groups. Changes of ascites volume, renal function, serum and urinary levels of Na+ and K+, blood vasoactive substance, and portal dynamics in patients before and after treatment were observed.</p><p><b>RESULTS</b>The total effective rate for ascites was 71.7% (43/60 cases) in the treatment group and 18.3% (11/60 cases) in the control group, showing significant difference between groups (P < 0.01). Significant difference of blood creatinine, urea nitrogen, serum Na+ levels, and urinary Na+/K+ ratio were shown in the treatment group (P < 0.01) before and after treatment, and between groups after treatment (P < 0.05, P < 0.01). Portal vein blood flow was significantly lowered in the treatment group after treatment (P < 0.01), which showed significant difference as compared with that in the control group (P < 0.01). Besides, levels of atrial natriuretic peptide, renin, angiotensin, nitric oxide, and aldosterone decreased and endotoxemia improved remarkably in the treatment group (P < 0.01). One-year follow-up showed that the ascites eliminating rate and the incidence of hepato-renal syndrome in the treatment group was 38.3% (23/60 cases) and 23.3% (14/60 cases) respectively, while in the control group 0 and 41.7% (25/60 cases) respectively, all showed statistical difference between groups (all P < 0.05).</p><p><b>CONCLUSION</b>Combined therapy of SHP and colonic dialysis with herbal medicine could effectively eliminate the ascites, improve the hemodynamic condition of portal and splenic veins, reduce the content of vasoactive substance and noxious substances like ammonia and endotoxin in blood, and lower the incidence of hepato-renal syndrome.</p>

Preneoplastic markers of hepatitis B virus-associated hepatocellular carcinoma and their significance in clinical settings / 中华肝脏病杂志

<p><b>OBJECTIVES</b>To identify serologic markers that may indicate the early presence of hepatocellular carcinoma (HCC), and analyze their significance in the pathogenesis of chronic hepatitis B.</p><p><b>METHODS</b>Hepatitis B x antigen (HBxAg) positive and negative HepG2 cells were subjected to PCR select cDNA subtraction to identify differentially expressed genes that may precede the development of HCC. These included the up-regulated genes URG4, URG7, URG11, and VEGFR3, and the down-regulated gene, Sui1. Specific ELISAs were constructed to measure differentially expressed antigens and their corresponding antibodies to determine whether they had prognostic and/or diagnostic value. The study population consisted of 730 people. Among them, 416 were HBsAg(-) and 298 were HBV carriers with chronic liver disease and/or HCC. In addition, 16 patients had non-viral hepatitis. Among these, serial serum samples from 53 HBsAg(+) patients with cirrhosis were collected and studied.</p><p><b>RESULTS</b>Antibodies to multiple differentially regulated genes were detectable in serum samples from patients with HBV associated cirrhosis and HCC, but not in serum samples from uninfected individuals (P < 0.01). Antibodies were undetectable in serum samples from HBV patients without liver disease and in serum samples from patients with other tumor types, and among those with non viral hepatitis. Among patients at high risk of developing HCC, these antibodies were found to be independent of nationality and ethnicity. Statistical analysis of the 28 HBsAg(+) patients with HCC showed that anti-URG11 and anti-VEGFR3 were the most frequently detected antibodies. These antibodies were found to coexist in 16 (P < 0.05). In contrast, among the 25 HBsAg(+) patients without HCC, anti-Sui1 and anti-URG7 were the most prevalent antibodies. These antibodies coexisted in 11 (P < 0.05). In addition, HCC patients with four or more antibodies detected before the appearance of HCC had a poorer survival outcome.</p><p><b>CONCLUSION</b>These antibodies can be detected in serum samples several months to several years before the appearance of HCC. This suggests that they may be preneoplastic markers that may help to distinguish which HBV carriers with cirrhosis are most likely to progress and develop HCC.</p>

Correlation between hepatic immunological markers and virus genotype in patients with chronic hepatitis C / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the hepatic expression of immunological markers relevant to a cytotoxic response in relation to viral genotype.</p><p><b>METHODS</b>The frozen liver biopsies were obtained from 28 HF genotyped patients and made the sections stained. The morphometry was used to analyze the major histocompatibility complex class I (MHC-I), CD8, beta(2)-microglobulin (beta(2) -mG), HFE and CD68 in the stained sections. Biopsy data of response to therapy with interferon were available in 18 cases.</p><p><b>RESULTS</b>CD8+ was usually clustered together and localized in portal tracts and sinusoids, and seen to interact with MHC I positive lining cells. MHC-I and beta(2) -mG were expressed mainly in endothelial and Kupffer cells. HFE was expressed in most round and dendritic CD68+ cells. Patients with virus genotype 3a had higher hepatic MHC-I and HFE expression, and a better sustained response to interferon (IFN) therapy than patients without.</p><p><b>CONCLUSION</b>The MHC-I expression in the liver of patient with chronic hepatitis C virus infection seems to relate to viral-genotype. The hepatic MHC-I and HFE expression are higher in patients with virus genotype 3a than that in patients with non-3a genotype.</p>

Effects of Shehuang Paste on hemodynamics, endotoxin, nitric oxide and endothelin-1 in patients with refractory cirrhotic ascites / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the influence of Shehuang Paste (SHP) to the hemodynamics, endotoxin, nitric oxide (NO), and endothelin-1 (ET-1) in patients with refractory cirrhotic ascites.</p><p><b>METHODS</b>Fifty-nine cases of refractory cirrhotic ascites were randomly assigned to two groups, 32 cases in the treatment group and 27 cases in the control group. The basic treatment was the same for both groups, including liver protecting medicines, diuretics and supportive drugs, but SHP navel sticking was applied for the treatment group additionally once a day. A course of one month of treatment was applied and the general efficacy on ascites was observed by the end of the therapeutic course. Before and after the treatment, examinations by limulus lysate chromogenic test was conducted to measure plasma endotoxin content; colorimetry to measure plasma content of NO indirectly, radioimmunoassay to measure plasma ET-1 content; and color Doppler ultrasonography to measure the blood flow of portal vein and splenic vein. The relationship between the blood flow of portal vein and splenic vein and endotoxin, NO and ET-1 in the treatment group was analyzed as well.</p><p><b>RESULTS</b>The total effective rate on ascites was 84.4% in the treatment group, and 48. 1% in the control group, with significant difference shown between them (P<0.01). In the treatment group the blood flow of portal vein and splenic vein, contents of endotoxin, NO and ET-1 all got significantly reduced after treatment ( P<0.05 or P<0.01); while these indexes in the control group were not significantly changed ( P 0.05). Moreover, it was found that in the treatment group, the blood flow of portal vein and splenic vein had a positive correlation to the levels of NO, ET-1, and endotoxin, either before or after treatment.</p><p><b>CONCLUSION</b>Application of SHP navel sticking could clearly reduce the blood flow of portal vein and splenic vein, and lower the content of endotoxin, NO and ET-1. The blood flow of portal vein and splenic vein in the treatment group showed a positive correlation with the contents of endotoxin, NO and ET-1. liver cirrhosis, refractory ascites, vasoactive substance, hemodynamics</p>
