RESUMO
Background/Aims@#The HBsAg levels have been used to monitor the chronic hepatitis B (CHB) treatment response to antiviral therapy.On the other hand, it is unclear if the HBsAg quantification levels at each treatment point differ according to the HBeAg status and drug in CHB patients. This study compared the changes in HBsAg in CHB patients according to the HBeAg status and treatment drugs. @*Methods@#CHB patients with at least 1 year of follow-up treatment with one drug, either entecavir (ETV) or tenofovir (TDF), were enrolled in this study. The mean HBsAg levels were measured annually for up to 6 years. A linear mixed model was used to compare the HBsAg quantification levels during the follow-up period. An independent samples t-test was used to analyze the differences in the HBsAg quantification levels at each treatment time point. @*Results@#Ninety-seven patients were enrolled in this study; 59 among them were HBeAg-positive. Two patients in the TDF group achieved HBsAg seroconversion. The HBsAg level decreased during the follow-up in the ETV and TDF groups. The HBsAg level was lower in the TDF group than the ETV group during the follow-up. On the other hand, subgroup analysis showed that this trend was the same only in the HBeAg-negative patients, not in the HBeAg-positive patients. In the HBeAg-negative patients, HBsAg level in the TDF group was significantly lower than that in the ETV group at 36, 48, and 72 months. The change in HBsAg level from the baseline increased at a decreasing rate during the follow-up in both groups. Furthermore, the change in the HBsAg level in the TDF group was significantly larger than that of the ETV group at 36 months in the HBeAg-negative patients. @*Conclusions@#Although TDF might be more efficient than ETV in reducing the HBsAg level in HBeAg-negative patients in a few years, HBsAg seroconversion occurred very rarely. A further large-scale, long-term study will be needed to confirm the antiviral effects on the HBsAg level.
RESUMO
Background/Aims@#Because hepatitis B virus (HBV) replication has been known to play animportant role in cancer recurrence after curative treatment of HBV-related hepatocellularcarcinoma (HCC), we examined whether treatment based on nucleos(t)ide analogues (NAs)might decrease the recurrence rate and improve patient survival. @*Methods@#The retrospective cohort study enrolled 73 patients with chronic hepatitis B whowere treated with transarterial chemoembolization (TACE) and radiofrequency ablation (RFA)with curative intent for HCC. Among those, 30 and 43 patients were treated with tenofovirdisoproxil fumarate (TDF) and entecavir (ETV), respectively. @*Results@#Of the 73 patients, 51 experienced HCC recurrence, and 14 patients were deadduring a follow-up of 73±34 months. Multivariate analyses showed that tumor size (hazardratio [HR], 1.590; 95% confidence-interval [CI], 1.106-2.285; P=0.012) and Child-Pugh class B(vs. class Aon cirrhosis; HR, 5.794; 95% CI, 2.311-14.523; P=0.001) was significantly associatedwith HCC recurrence, and Child-Pugh class B (HR, 7.357; 95% CI, 2.100-25.777; P=0.002) was anindependent unfavorable prognostic factor for survival. During NAs therapy, TDF was superiorto ETV for complete viral response at 1 year after the date of combination of TACE and RFA(P=0.016). However, the risks of HCC recurrence and survival were not significantly differentbetween those treated with TDF versus ETV. @*Conclusions@#TDF was superior to ETV for achieving complete viral response. However, therecurrence and mortality after TACE and RFA for HBV-related HCC were not significantlydifferent between patients treated with TDF versus ETV.

RESUMO
Chronic hepatitis C (CHC) treatment has dramatically improved since direct-acting antiviral (DAA) therapy was introduced. However, the use of DAA therapy in CHC patients with hepatocellular carcinoma (HCC) remains controversial. We investigated the DAA treatment response in CHC patients with HCC. Methods: We retrospectively analyzed CHC patients treated with DAA from 2016 to 2018. Patients were divided into two groups based on their HCC-history before DAA therapy. Baseline characteristics, sustained virologic response at 12 weeks (SVR 12), and HCC recurrence after DAA therapy were evaluated. We also used propensity score matching (PSM) in a 2:1 ratio to reduce confounding variables. Results: A total of 192 patients were enrolled; 78.1% were treatment-naïve, and 34.9% had liver cirrhosis (LC). Among these patients, 168 did not have HCC, and 24 had HCC. The HCC group was older (57.0 years vs. 72.0 years, p < 0.001), had a higher incidence of LC (26.2% vs. 95.8%, p < 0.001), fibrosis-4 index (2.6 vs. 9.2, p < 0.001), liver stiffness measurement (7.0 kPa vs. 17.4 kPa, p = 0.012), and α-fetoprotein (4.4 ng/mL vs. 8.2 ng/mL, p ≤ 0.001). The SVR 12 rate was 97.0% in the non- HCC group and 91.7% in the HCC group (p = 0.213). HCC recurrence was observed in 14 patients (58.3%) in the HCC group. Conclusions: DAA treatment efficacy in CHC patients with or those without HCC were not significantly different, and HCC recurrence was relatively common.
RESUMO
BACKGROUND/AIMS: A switch to systemic therapy, such as sorafenib, should be considered for hepatocellular carcinoma (HCC) patients refractory to transarterial chemoembolization (TACE). On the other hand, treatment changes are difficult if the liver function worsens to Child-Pugh B or C. Therefore, predicting the risk factors for non-responsiveness to TACE and deteriorating liver function may be helpful.METHODS: Newly diagnosed Child-Pugh A HCC patients who underwent TACE from January 2012 to June 2018 were included. After 1 year, this study evaluated whether there was a treatment response to TACE and whether the Child-Pugh class had worsened.RESULTS: Among 121 patients, 65 were refractory and 56 responded to TACE. In multivariable logistic regression analysis, the tumor size, tumor number, and albumin at the time of the diagnosis of HCC were significant prognostic factors for the treatment response to TACE. Among 65 patients who presented TACE-refractoriness, 27 showed liver function deterioration from Child-Pugh class A to class B or C after TACE. In multivariable logistic regression analysis, bilirubin at the diagnosis of HCC was a significant prognostic factor for liver function deterioration. A predictive algorithm based on the regression equations revealed a sensitivity, specificity, positive predictive value, and negative predictive value of 74.1%, 74.5%, 45.5%, and 90.9%, respectively, for TACE-refractoriness and liver function deterioration.CONCLUSIONS: The prognostic model incorporating the tumor size, tumor number, albumin, and bilirubin at the diagnosis of HCC may help identify patients who show a poor response to TACE and aggravation of liver function after TACE, who may benefit from early switching into systemic therapy before liver function aggravation.
RESUMO
Background/Aims@#Intrahepatic cholangiocarcinoma (ICC) is the second-most common primary liver malignancy, arising from the peripheral intrahepatic bile duct epithelium. Hepatitis B virus (HBV) or hepatitis C virus (HCV) may be involved in the development of ICC. We explored the prognostic value of hepatitis virus infection, as well as other prognostic factors affecting survival in patients with ICC. @*Methods@#A retrospective chart review was performed for patients diagnosed with ICC between August 2005 and December 2018 at Konkuk University Medical Center. We identified a total of 131 patients with ICC. Overall survival rates of patients with and without hepatitis were determined. Univariate and multivariate analyses were used to estimate factors influencing survival outcomes. @*Results@#A total of 17.6% (23/131) of patients were positive for HBV or HCV. Hepatitis B positive ICC patients were significantly younger with higher albumin and higher α-fetoprotein than those without hepatitis viral infections. The median survival of hepatitis-positive and hepatitis-negative groups was 280 and 213 days, respectively. Survival rates were not significantly different between the two groups (p = 0.279). Multivariate analyses indicated that lower serum carbohydrate antigen 19-9 (CA 19-9) (p < 0.001), lower T stage (p = 0.042), the absence of lymph-node metastasis (p = 0.043), and receiving curative surgery (p = 0.033) were independent predictors of better outcomes. @*Conclusions@#While hepatitis influenced a number of clinical features in ICC patients, it did not affect survival rate. Prognostic factors influencing survival outcomes with ICC were CA 19-9 level, T stage, the presence of lymph node metastasis, and curative surgery.
RESUMO
BACKGROUND: The pain-relief properties of tricyclic antidepressants can be attributed to several actions. Recent observations suggest that adenosine is involved in the antinociceptive effect of amitriptyline. The A3 adenosine receptor (A3AR) is the only adenosine subtype overexpressed in inflammatory and cancer cells. This study was performed to investigate the role of A3AR in the anti-nociceptive effect of amitriptyline. METHODS: Spinal nerve-ligated neuropathic pain was induced by ligating the L5 and L6 spinal nerves of male Sprague-Dawley rats. The neuropathic rats were randomly assigned to one of the following three groups (8 per group): a neuropathic pain with normal saline group, a neuropathic pain with amitriptyline group, and a neuropathic pain with amitriptyline and 3-ethyl-5-benzyl- 2-methyl-4-phenylethynyl-6-phenyl-1,4-(±)-dihydropyridine-3,5-dicarboxylate (MRS) group. Amitriptyline or saline was administered intraperitoneally and 3-ethyl-5-benzyl-2-methyl-4-phenylethynyl-6-phenyl-1,4-(±)-dihydropyridine-3,5-dicarboxylate (MRS-1191), an A3AR antagonist, was injected subcutaneously immediately before amitriptyline administration. The level of extracellular signal-regulated kinase P44/42 (ERK1/2), cyclic AMP response element-binding protein (CREB), and proinflammatory cytokines were assessed using immunoblotting or reverse-transciption polymerase chain reaction. RESULTS: Amitriptyline increased the mechanical withdrawal threshold of the neuropathic rats. The level of phospho-ERK1/2 and phospho-CREB proteins, and proinflammatory cytokines produced by spinal nerve ligation were significantly reduced by amitriptyline administration. However, the use of MRS-1191 before amitriptyline administration not only reduced the threshold of mechanical allodynia, but also increased the signaling protein and proinflammatory cytokine levels, which were reduced by amitriptyline. CONCLUSIONS: The results of this study suggest that the anti-nociceptive effect of amitriptyline involves the suppression of ERK1/2 and CREB signaling proteins, and A3AR activation also affects the alleviation of the inflammatory response.

BACKGROUND/AIMS: Surgical resection or ablation is recommended for the treatment of early hepatocellular carcinoma (HCC), whereas transarterial chemoembolization (TACE) is frequently used in early HCC ineligible for curative resection. We evaluated the clinical effects and safety of radiofrequency ablation (RFA) shortly after TACE in patients with Barcelona clinic liver cancer (BCLC) stage A HCC. METHODS: Sixty-seven BCLC stage A HCC patients who failed to achieve complete response to TACE as either a first line treatment and who subsequently received RFA at the Konkuk University Medical Center from January 2005 to December 2017 were included. Evaluation indices included treatment response, overall survival rate, recurrence-free survival, prognostic factors, and procedure-related complications. RESULTS: Median follow-up was 46.9 months. Fifty-four (80.6%) patients were of Child-Pugh class A, and 13 (19.4%) were of class B. Modified UICC stages were I in 10 (14.9%), II in 46 (68.7%), and III in 11 (16.4%) patients. In the 67 study subjects, cumulative recurrence-free survival rates were 86.8%, 55.9% and 29.7% at 1, 3, and 5 years, respectively, and overall survival rates were 100%, 93.4%, and 83.5% at 1, 3, and 5 years, respectively. Tumor size significantly predicted recurrence. No treatment-related death occurred. CONCLUSIONS: Combination of RFA was an efficient and safe treatment for BCLC stage A HCC patients that failed to achieve complete response to initial TACE. We suggest TACE plus RFA be considered as a curative option for early HCC patients ineligible for curative resection of RFA.

RESUMO
BACKGROUND: Spontaneous bacterial peritonitis (SBP) is a serious infectious complication in patients with liver cirrhosis. However, information about prognosis of SBP in hepatocellular carcinoma (HCC) patients is limited. We investigated the clinical course of SBP in HCC patients. METHODS: This study enrolled patients diagnosed with SBP between 2005 and 2017. Medical records of patients were reviewed and clinical course was compared between the non-HCC and HCC groups. RESULTS: In total, 123 SBP cases including 49 HCC cases were enrolled. Men were predominant (48/74, 64.9% vs. 34/49, 69.4%; P = 0.697); median age was 58 years in both non-HCC and HCC groups (P = 0.887). The most common etiology was alcohol (32/74, 43.2%) in non-HCC group and hepatitis B (30/49, 61.2%) in HCC group (P = 0.009). Antibiotic resistance rate was higher in non-HCC than in HCC group (29.7% vs. 12.2%; P = 0.028); in-hospital mortality did not differ between the groups (25/74, 33.8% vs. 13/49, 26.5%; P = 0.431). Development rate of hepatorenal syndrome did not differ between non-HCC and HCC group (14/74, 18.9% vs. 10/49, 20.4%; P = 1.000), but hepatic encephalopathy was less common in HCC group (26/74, 35.2% vs. 9/49, 18.3%; P = 0.008). The most important predictor of in-hospital mortality in patients with HCC was white blood cell count above 11,570 cells/mm3 (odds ratio, 6.629; 95% confidence interval, 1.652–26.590; P = 0.008). CONCLUSION: Prognosis of SBP in HCC patients is relatively less severe. This result may be related with reduced antibiotics resistance and lower development rates of other complications, such as hepatic encephalopathy. Degree of systemic inflammation may be the most important factor for in-hospital mortality.

BACKGROUND/AIMS: Direct-acting antiviral (DAA) therapy has been shown to achieve a high rate of sustained virologic response (SVR) and favorable outcomes in chronic hepatitis C (CHC) patients. We investigated the virologic response and its clinical impact in CHC patients. METHODS: CHC patients with compensated liver function treated with DAAs between 2016 and 2017 were included for retrospective analysis. We analyzed baseline characteristics and virologic and biochemical responses at on-treatment 4 weeks, end of treatment, and post-treatment 12 weeks. Fibrosis was measured as liver stiffness measurement by transient elastography (FibroScan). Adverse events were monitored during the treatment period. RESULTS: A total of 135 patients (61.5% with genotype [GT] 1b and 38.5% with GT 2a) were enrolled 47.4% were male, 79.3% were treatment naive, and 30.4% had cirrhosis. SVR 12 was observed in 97.6% (81/83) in the GT 1b and 98.1% (51/52) in the GT 2a; treatment with daclatasvir+asunaprevir was the most commonly used in GT 1b (55/83), and sofosbuvir+ribavirin was the most commonly used in GT 2a (49/52). The median change of liver stiffness measurement at two time points using the signed rank test was -3.2 kPa in patients who underwent transient elastography before treatment and at SVR 12 (n=25). The most common adverse events were anemia, dyspepsia, and insomnia. One GT 2a patient treated with sofosbuvir+ribavirin stopped the treatment at 8 weeks due to symptomatic bradyarrhythmia; however, he recovered spontaneously and achieved SVR 12. CONCLUSIONS: DAA treatment of chronic hepatitis C genotype 1b and 2a resulted in a high rate of sustained virologic response and improvement of liver fibrosis score.

BACKGROUND/AIMS: Direct sequencing is the gold standard for the detection of drug-resistance mutations in hepatitis B virus (HBV); however, this procedure is time-consuming, labor-intensive, and difficult to adapt to high-throughput screening. In this study, we aimed to develop a dendron-modified DNA microarray for the detection of genotypic resistance mutations and evaluate its efficiency. METHODS: The specificity, sensitivity, and selectivity of dendron-modified slides for the detection of representative drug-resistance mutations were evaluated and compared to those of conventional slides. The diagnostic accuracy was validated using sera obtained from 13 patients who developed viral breakthrough during lamivudine, adefovir, or entecavir therapy and compared with the accuracy of restriction fragment mass polymorphism and direct sequencing data. RESULTS: The dendron-modified slides significantly outperformed the conventional microarray slides and were able to detect HBV DNA at a very low level (1 copy/μL). Notably, HBV mutants could be detected in the chronic hepatitis B patient sera without virus purification. The validation of our data revealed that this technique is fully compatible with sequencing data of drug-resistant HBV. CONCLUSIONS: We developed a novel diagnostic technique for the simultaneous detection of several drug-resistance mutations using a dendron-modified DNA microarray. This technique can be directly applied to sera from chronic hepatitis B patients who show resistance to several nucleos(t)ide analogues.

BACKGROUND/AIMS: Little is known about the effect of early flares on response during first-line tenofovir disoproxil fumarate (TDF) treatment for chronic hepatitis B (CHB). The aim of this study was to investigate the incidence and outcome of early alanine aminotransferase (ALT) flare in treatment-naive patients with CHB during long-term TDF monotherapy. METHODS: One hundred eighty-one treatment-naive CHB patients were treated with a 300-mg once-daily dose of TDF for more than 12 weeks. Virological markers of hepatitis B virus (HBV) and biochemical data were measured at baseline and every 4-12 weeks during the therapy. The proportion of patients with undetectable HBV DNA level (5 × upper limit of the normal range) occurred in seven patients (3%) without viral breakthrough within the first 8 weeks after the start of TDF monotherapy. Among them, six patients were HBeAg-positive and one patient was HBeAg-negative. All cases of early ALT flares resolved within 4 weeks and virologic response was observed in all patients without interruption or discontinuation of treatment. CONCLUSIONS: Continuous TDF monotherapy was effective and safe in treatment-naive patients with CHB who experienced early ALT flares followed by a decrease in HBV DNA level.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) is one of critical complications in liver cirrhosis patients with ascites. We aimed to review clinical course of SBP patients in a 10-year period from single center. METHODS: This study enrolled SBP patients between 2005 and 2015. Their medical records were reviewed. The laboratory findings of serum and ascites were examined, and characteristics of isolated microorganisms in ascites were analyzed. RESULTS: Total 51 patients were enrolled. Male patients were predominant (64.7%), and mean age was 59.20 years. The most common etiology of cirrhosis was alcohol (41.2%), followed by hepatitis B (39.2%). Microorganism was isolated from the ascites in 31 patients (60.78%). The proportions of Gram negative and Gram positive were 80.64% and 19.36%. The proportions of Escherichia coli, Klebsiella, and Streptococcus species were 29.41%, 19.61% and 11.76%. Among Escherichia colis, 4 cases were ESBL positive (7.84%). The most commonly used first-line antibiotic was cefotaxime (80.40%). Prophylactic antibiotics treatment was performed only in 8 patients, and SBP was recurred in 7 patients (13.72%). When comparing the SBP recurrence group and the non-recurrence group, there were no significant differences in laboratory findings of serum and ascitic fluid. CONCLUSIONS: SBP is still a critical complication in cirrhosis patients with ascites, and the clinical features of SBP have not been altered much compared with those in 1990's. The effective treatment of SBP is still very important for a better prognosis of cirrhosis patients.

Transurethral resection has been the gold standard in the operative management of benign prostatic hyperplasia and bladder tumor; however, it is associated with several complications that may cause patient discomfort. We evaluated the usefulness of continuous infusion of dexmedetomidine on emergence agitation, hemodynamic status, and recovery profiles in patients undergoing elective surgery by a randomized clinical trial. Sixty patients aged 30 to 80 yr who were scheduled for elective transurethral resection under general anesthesia were included in this study. Participants were randomly assigned to two groups (control group, group C; dexmedetomidine group, group D). A total of 60 male patients were enrolled in this study and randomly assigned to group C (n=30) or group D (n=30). The quality of emergence in group D was marked by a significantly lower incidence of emergence agitation than in group C (P=0.015). Patients in group D therefore felt less discomfort induced by the indwelling Foley catheter than those in group C (P=0.022). No statistically significant differences were found between the two groups with respect to side effects including bradycardia (P=0.085), hypotension (P=0.640), and postoperative nausea and vomiting (P=0.389). Our study showed that intraoperative dexmedetomidine infusion effectively reduced the incidence and intensity of emergence agitation and catheter-induced bladder discomfort without delaying recovery time and discharge time, thus providing smooth emergence during the recovery period in patients undergoing transurethral resection (Clinical Trial Registry No. KT0001683).

BACKGROUND/AIMS: Nucleos(t)ide analogues (NAs) help reduce the recurrence rate after the curative treatment of hepatitis B related hepatocellular carcinoma (HCC). Sorafenib has been shown to improve survival of advanced HCC patients. Whether antiviral therapy with NAs could help such patients is unknown. Our aim is to investigate the usefulness of antiviral therapy for advanced-stage HCC treated with sorafenib. METHODS: We performed a retrospective cohort study in advanced-stage HCC patients treated with sorafenib between June 2007 and December 2013. Patients in group A (the non-antiviral therapy group) were treated with sorafenib alone. Those in group B (the antiviral therapy group) were treated with sorafenib and NAs. Progression-free survival (PS) and overall survival (OS) were compared between these two groups. RESULTS: Finally, 23 patients in group A and 40 patients in group B were enrolled in the study. The mean number of days of treatment with sorafenib was 79 (34-231) days and 96 (33-449) days for group A and B, respectively (P=0.286). The mean PS of group A and B was 97 (14-449) days and 51 (0-461) days, respectively (P=0.068). The OS was 154 (44-741) days in group A and 138 (30-1,025) days in group B (P=0.665). PS and OS showed no significant difference between the two groups. CONCLUSIONS: This study shows that there was no significant survival gain of using antiviral therapy in patients with advanced-stage HCC treated with sorafenib. In consideration of cost-effectiveness, antiviral therapy may be not mandatory.

BACKGROUND: Gamma or X-ray irradiation of blood components is used to prevent transfusion associated graft-versus-host disease (TA-GVHD). In this study, we assessed the current status of irradiated blood components and blood irradiators in Korean medical institutes. METHODS: We surveyed 306 medical institutes in Korea by a questionnaire, between August 2015 and October 2015. Institutions were asked to answer 9~16 questions, including whether they had facilities for irradiation of blood, type of irradiators used, dose of irradiation used, and if they did not have irradiation facilities, they were asked whether their blood components were irradiated. RESULTS: One-hundred and ninety-seven (64.4%) out of 306 questionnaires were returned and analyzed: 96 institutions provide irradiated blood, and 101 institutions do not use irradiated blood components. Forty-eight institutions have on site facilities with gamma blood irradiator for the irradiation of blood components and uses a dose of 20 to 50 Gy. Of the 48 institutions without facilities that use irradiated blood components, 38 (79.2%) have their blood components by referral to Korean Red Cross Blood Centers and 9 (18.8%) refer to other medical institutes for their irradiation needs. The survey showed that there is lot of regional variation in the supply and demand of irradiated blood components in Korea. CONCLUSION: Our survey does suggest that the establishment of the supply system for irradiated blood component by nation-wide blood establishments may provide national nuclear safety and stability of irradiated blood supply. It may also alleviate some regional disparity for the transfusion service of irradiated blood in Korea.

We aimed to compare fentanyl, remifentanil and dexmedetomidine with respect to hemodynamic stability, postoperative pain control and achievement of sedation at the postanesthetic care unit (PACU). In this randomized double-blind study, 90 consecutive total laparoscopic hysterectomy patients scheduled for elective surgery were randomly assigned to receive fentanyl (1.0 µg/kg) over 1 minute followed by a 0.4 µg/kg/hr infusion (FK group, n = 30), or remifentanil (1.0 µg/kg) over 1 minute followed by a 0.08 µg/kg/min infusion (RK group, n = 30), or dexmedetomidine (1 µg/kg) over 10 minutes followed by a 0.5 µg/kg/hr infusion (DK group, n = 30) initiating at the end of main procedures of the operation to the time in the PACU. A single dose of intravenous ketorolac (30 mg) was given to all patients at the end of surgery. We respectively evaluated the pain VAS scores, the modified OAA/S scores, the BIS, the vital signs and the perioperative side effects to compare the efficacy of fentanyl, remifentanil and dexmedetomidine. Compared with other groups, the modified OAA/S scores were significantly lower in DK group at 0, 5 and 10 minutes after arrival at the PACU (P < 0.05), whereas the pain VAS and BIS were not significantly different from other groups. The blood pressure and heart rate in the DK group were significantly lower than those of other groups at the PACU (P < 0.05). DK group, at sedative doses, had the better postoperative hemodynamic stability than RK group or FK group and demonstrated a similar effect of pain control as RK group and FK group with patient awareness during sedation in the PACU.

BACKGROUND/AIMS: Before tenofovir (TDF) become available in South Korea, combination therapy with entecavir (ETV) and adefovir (ADV) was the most potent regimen for chronic hepatitis B (CHB) patients who fail to respond to rescue therapy for drug resistance. We analyzed the efficacy of ETV-ADV combination therapy and investigated the clinical and clonal results of TDF-based rescue therapy in CHB patients refractory to this combination. METHODS: We retrospectively reviewed the medical records of CHB patients treated for up to 3 years with ETV-ADV combination therapy as a rescue therapy for drug resistance. In cases refractory to this combination, clinical and clonal analyses were performed for TDF-based rescue therapy. RESULTS: The analysis was performed on 48 patients. Twelve patients achieved a virological response (VR) within 3 years. A VR was subsequently achieved in nine of the ten patients without a VR who switched to TDF monotherapy. A VR was also achieved in six of the seven patients who switched to lamivudine-TDF combination therapy, and in two of the two patients who switched to ETV-TDF combination therapy. In an in vitro susceptibility test, viral replication was detected with TDF monotherapy but not with ETV-TDF combination therapy. CONCLUSIONS: The efficacy of ETV-ADV combination therapy was insufficient in CHB patients who were refractory to rescue therapy. A more potent regimen such as ETV-TDF combination therapy may be considered in such refractory cases.
