RESUMO

INTRODUCTION: For the treatment of spontaneous bacterial peritonitis (SBP), cefotaxime, ceftriaxone, and ciprofloxacin were used as first-line agents. However, considering the increasing rate of antibiotic resistance, it is unclear which of these drugs can be initially recommended. This study aimed to compare the current efficacy of the 3 antibiotics, namely cefotaxime, ceftriaxone, and ciprofloxacin, for the treatment of SBP in patients with cirrhosis with ascites, when guided by therapeutic responses. METHODS: This study was a multicenter, prospective, randomized controlled trial. The inclusion criteria were 16- to 75-year-old patients with liver cirrhosis with ascites, having polymorphonuclear cell count of >250/mm 3 . We performed a follow-up paracentesis at 48 hours to decide continuing or changing the assigned antibiotics and then assessed the resolution rates at 120 and 168 hours of treatment. RESULTS: A total of 261 patients with cirrhosis who developed SBP were enrolled. Most of the patients were diagnosed as those with SBP within 48 hours of admission. The resolution rates at 120 hours, which is the primary endpoint, were 67.8%, 77.0%, and 73.6% in the cefotaxime, ceftriaxone, and ciprofloxacin groups, respectively ( P = 0.388), by intension-to-treat analysis. The 1-month mortality was similar among the groups ( P = 0.770). The model for end-stage liver disease score and the SBP resolution were significant factors for survival. CONCLUSION: The efficacy of empirical antibiotics, such as cefotaxime, ceftriaxone, and ciprofloxacin, against SBP was not significantly different. In addition, these antibiotics administered based on response-guided therapy were still efficacious as initial treatment for SBP, especially in those with community-acquired infections.

RESUMO

Background/Aims Regorafenib has been approved as a second-line systemic therapy for hepatocellular carcinoma (HCC) patients after the phase III RESORCE trial. This study analyzed real-world data to assess the clinical effectiveness and safety of regorafenib compared to the RESORCE trial. Methods This multicenter cohort study included HCC patients treated with regorafenib after sorafenib (n = 133). We evaluated the time to progression (TTP), progression-free survival (PFS), overall survival (OS), and safety in patients receiving regorafenib along with the predictors of prognosis. Results The median age was 60 years and 81.2% patients were men. Hepatitis B virus infection (68.4%) was the commonest etiology. Most patients were classified as Child-Pugh A (98.5%) and had extrahepatic metastasis (84%) and vascular invasion (45.1%). This study demonstrated similar characteristics apart from more frequent hepatitis B etiology and more vascular or extrahepatic involvement compared with the RESORCE trial. An objective response rate of 12.5% was obtained for response assessment (n = 112); the disease control rate was 34.8%. Thirty-eight patients died during follow-up. With regorafenib, the median OS, PFS, and TTP were 10.0, 2.7, and 2.6 months, respectively. In the exploratory analysis after sorafenib administration, the median OS was 25.8 months. The rate of response and survival were comparable to those in the RESORCE trial. Child-Pugh score > 5, alpha-fetoprotein > 400 ng/ml, and TTP for sorafenib ≥ median were independently associated with OS. Conclusions This real-word regorafenib study showed comparable effectiveness and safety to the RESORCE trial. Regorafenib improves the prognosis of patients with prolonged TTP during previous sorafenib therapy.

RESUMO

BACKGROUND/AIMS: Sorafenib is the first approved systemic treatment for advanced hepatocellular carcinoma (HCC). However, its clinical utility is limited, especially in Asian countries. Several reports have suggested the survival benefits of hepatic arterial infusion chemotherapy (HAIC) for advanced HCC with main portal vein tumor thrombosis (PVTT). This study aimed to compare the efficacy of sorafenib-based therapy with that of HAIC-based therapy for advanced HCC with main PVTT. METHODS: Advanced HCC patients with main PVTT treated with sorafenib or HAIC between 2008 and 2016 at Korea University Medical Center were included. We evaluated overall survival (OS), time-to-progression (TTP), and the disease control rate (DCR). RESULTS: Seventy-three patients were treated with sorafenib (n=35) or HAIC (n=38). Baseline characteristics were not significantly different between groups, except the presence of solid organ metastasis (46% vs 5.3%, p<0.001). The median OS time was not significantly different between the groups (6.4 months vs 10.0 months, p=0.139). TTP was longer in the HAIC group than in the sorafenib group (2.1 months vs 6.2 months, p=0.006). The DCR was also better in the HAIC group than in the sorafenib group (37% vs 76%, p=0.001). Subgroup analysis, which excluded patients with extrahepatic solid organ metastasis, showed the same trends for the median OS time (8.8 months vs 11.1 months, p=0.097), TTP (1.9 months vs 6.0 months, p<0.001), and DCR (53% vs 81%, p=0.030). CONCLUSIONS: HAIC-based therapy may be an alternative to sorafenib for advanced HCC with main PVTT by providing longer TTP and a better DCR.

RESUMO

OBJECTIVES: For the prevention of spontaneous bacterial peritonitis (SBP) in cirrhotic patients with ascites, norfloxacin 400 mg per day is recommended as a standard regimen. This study aims to investigate whether ciprofloxacin once weekly administration is not inferior to norfloxacin once daily administration for the prevention of SBP. METHODS: This is an investigator-initiated open-label randomized controlled trial conducted at seven tertiary hospitals in South Korea. Liver cirrhosis patients with ascites were screened, and enrolled in this randomized controlled trial if ascitic protein ≤1.5 g/dL or the presence of history of SBP. Ascitic polymorphonucleated cell count needed to be <250/mm3. Patients were randomly assigned into norfloxacin daily or ciprofloxacin weekly group, and followed-up for 12 months. Primary endpoint was the prevention of SBP. RESULTS: One hundred twenty-four patients met enrollment criteria and were assigned into each group by 1:1 ratio (62:62). Seven patients in the norfloxacin group and five patients in the ciprofloxacin group were lost to follow-up. SBP developed in four patients (4/55) and in three patients (3/57) in each group, respectively (7.3% vs. 5.3%, P = 0.712). The transplant-free survival rates at 1 year were comparable between the groups (72.7% vs. 73.7%, P = 0.970). Incidence of infectious complication, hepatorenal syndrome, hepatic encephalopathy, and variceal bleeding rates were not significantly different (all P = ns). The factors related to survival were models representing underlying liver function. CONCLUSION: Once weekly ciprofloxacin was as effective as daily norfloxacin for the prevention of SBP in cirrhotic patients with ascites.

RESUMO

Since sorafenib was introduced in 2007 for treating advanced hepatocellular carcinoma (HCC), 15 patients have achieved a complete response (CR) in advanced HCC. However, only four of these reports can be regarded as real CRs involving adequate assessments including imaging, serum tumor markers, and histologic examinations of completely resected specimens. A 54-year-old man with hepatitis C virus (HCV)-related liver cirrhosis (LC) presented to our unit. A CT scan demonstrated a 3.8-cm arterial hypervascular/portal-washout mass in the right lobe and invasion in the right portal vein. Twelve weeks after beginning sorafenib therapy, the AFP level was normalized and a CT scan showed a prominent decrease in the hepatic mass and a significant decrease in the volume of portal vein thrombosis (PVT). The patient received a right liver hemihepatectomy after 12 months. No viable tumor cells were found in the resected specimen, and there was no thrombotic obstruction of the portal vein. Twelve months later the patient showed no clinical evidence of HCC recurrence. This is the first case of CR in HCC treatment following sorafenib with histologically confirmed HCV-related HCC without LC evidence, HCC with PVT, and a follow-up of longer than 12 months. This case seems to be an extremely unusual clinical outcome in advanced HCC.

RESUMO

The prognostic role of aberrant serum miRNA expression for predicting response to sorafenib treatment in advanced hepatocellular carcinoma (HCC) patients has not been well characterized. We aimed to identify specific serum miRNAs that are associated with positive radiologic responses or improved survival in sorafenib-treated HCC patients. miR-18a, miR-21, miR-139-5p, miR-221, miR-224, and miR-10b-3p, were selected for analysis. Serum samples from 24 patients with advanced stage HCC and 25 patients with liver cirrhosis (LC) were analyzed. All of the miRNAs except miR-21 were found to be upregulated in serum samples from HCC patients. None of the miRNAs assayed differed significantly in terms of expression between the responder and non-responder groups among HCC patients. However, miR-10b-3p levels were significantly higher in the subgroup of HCC patients with worse overall survival (fold change = 5.8, P = 0.008). Serum miRNA-10b-3p was upregulated in the presence of macrovascular invasion (MVI), and those with higher serum miRNA-10b-3p had significantly shorter survival during treatment (P = 0.042). Although no single serum miRNA was predictive of response to sorafenib treatment, analysis of serum miR-10b-3p levels may be valuable for diagnosis of HCC and prediction of survival of sorafenib-treated patients.

RESUMO

Tenofovir disoproxil fumarate (TDF) is one of the most widely used treatment options for human immunodeficiency virus (HIV) and HBV infections. Despite its efficacy and safety, some cases of nephrotoxicity have been reported in the treatment of HIV patients. Even more recently, very few cases of Fanconi syndrome associated with tenofovir therapy in HBV monoinfection have been reported. Herein, we report a case of a 47-year-old male with an HBV monoinfection, who developed Fanconi syndrome and a secondary osteomalacia with multiple bone pain. After TDF withdrawal and supplementation of calcitriol, his renal function was reverted. Although the overall risk of TDF-associated nephrotoxicity is very low, both glomerular and tubular function should be monitored in patients undergoing TDF treatment.

RESUMO

BACKGROUND: The aim of this study was to compare the efficacy of hepatic arterial infusion chemotherapy (HAIC) and sorafenib in advanced hepatocellular carcinoma (HCC) patients with portal vein tumor thrombosis (PVTT). METHODS: A total of 110 patients were observed between February 2008 and May 2013 in seven Korean centers. Fifty patients were treated with HAIC, and 60 patients were treated with sorafenib. RESULTS: The disease control rate in the HAIC was significantly higher than that in the sorafenib group (p < 0.001), although there was no significant difference in the objective response rate (p = 0.214). The median overall survival (OS) was significantly longer in the HAIC group than in the sorafenib group (7.1 vs. 5.5 months, p = 0.011). The median time to-progression (TTP) was also significantly longer in the HAIC group than in the sorafenib group (3.3 vs. 2.1 months, p = 0.034). In the multivariate analysis, tumor diameter (≥ 10 cm) and the absence of combined loco-regional treatment were significant prognostic factors influencing OS (p = 0.002 and p = 0.010, respectively) and TTP (p = 0.017 and p = 0.006, respectively). The treatment modality tended to be a significant prognostic factor for survival (p = 0.052), but not for tumor progression (p = 0.121). CONCLUSIONS: HAIC is comparable with sorafenib in terms of OS and TTP in advanced HCC patients with PVTT. HAIC shows more favorable treatment responses compared with sorafenib. Therefore, HAIC might be an alternative treatment modality to sorafenib in advanced HCC patients with PVTT.

RESUMO

GOALS: The goal of the study was to compare the efficacy and safety of sorafenib with those of systemic cytotoxic chemotherapy. BACKGROUND: Sorafenib treatment has shown to improve the survival in patients with advanced hepatocellular carcinoma (HCC) when compared with placebo. However, whether sorafenib controls advanced-stage HCC better than systemic cytotoxic chemotherapy has not been elucidated. STUDY: We retrospectively reviewed the medical records of 220 patients with measurable advanced HCC who had not received systemic treatment previously between January 2007 and April 2012. Among these patients, 78 had been treated with sorafenib. Another 14 patients who were treated with a 4-weekly regimen of adriamycin, cisplatin, and capecitabine were included as the historical control group for comparison. The median overall survival, the progression-free survival, response rates, and safety profiles were evaluated. RESULTS: Baseline characteristics were similar between the treatment groups. The median overall survival was 7.2 months [95% confidence interval (CI), 5.6-8.8] in the sorafenib group and 11.2 months (95% CI, 8.1-14.2) in the cytotoxic chemotherapy group (P=0.10). The median progression-free survival was 3.2 months (95% CI, 2.2-4.3) in the sorafenib group and 5.9 months (95% CI, 3.6-8.2) in the cytotoxic chemotherapy group (P=0.07). The deterioration of liver function and neutropenia were the most frequent serious adverse events in the sorafenib and the systemic chemotherapy group. CONCLUSIONS: Although a direct head-to-head comparison could not be done, there were some patients who showed a good response to systemic cytotoxic chemotherapy. Further assessment is necessary to study the role of chemotherapy in patients who are intolerant or intractable to sorafenib.

RESUMO

OBJECTIVE: To investigate the association between serum 25-hydroxyvitamin D [25(OH)D] levels and nonalcoholic fatty liver disease (NAFLD) independent of visceral obesity in Koreans and to examine whether the associations differ according to the presence of diabetes or insulin resistance. RESEARCH DESIGN AND METHODS: A total of 1081 adults were enrolled from a population-based cohort in Ansan city. Serum 25(OH)D concentrations were measured in all subjects. Insulin resistance was measured by homeostasis model assessment of insulin resistance (HOMA-IR). Using computed tomography, NAFLD was diagnosed if the liver attenuation index (LAI, the difference between the mean hepatic and splenic attenuation) was <5 Hounsfield Units. RESULTS: In subjects with diabetes (n = 282), 25(OH)D levels were negatively associated with waist circumference, fasting insulin, HOMA-IR, triglyceride levels, and visceral abdominal fat, and were positively associated with LAI after adjusting for age, sex, season, exercise, and vitamin supplementation. In subjects without diabetes, only triglyceride level was negatively associated with 25(OH)D. The adjusted odds ratio (OR) for NAFLD increased sequentially across decreasing quartiles of 25(OH)D in subjects with diabetes even after adjusting for visceral fat [Q1 vs. Q4; OR for NAFLD 2.5 (95% CI:1.0-6.2)]. In contrast, no significant difference in OR was observed in subjects without diabetes. When we classified non-diabetic subjects by HOMA-IR, an increase in the OR for NAFLD across decreasing quartiles of 25(OH)D was observed in the high HOMA-IR (≥2.5) group [n = 207, Q1 vs. Q4; OR 3.8(1.4-10.3)], but not in the low HOMA-IR (<2.5) group [n = 592, OR 0.8 (0.3-1.9)]. CONCLUSIONS: Low vitamin D status is closely associated with NAFLD, independent of visceral obesity in subjects with diabetes or insulin resistance.

RESUMO

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death in Korea. Curative treatment is only possible when the disease is diagnosed at the early stage. The prognosis of patients with HCC is even dismal in advanced stages. No systemic cytotoxic chemotherapy has proven to be beneficial in overall survival. Recently, the understanding of the molecular pathogenesis led to the development of new therapies. With the evidence of dysregulation of critical genes associated with cellular proliferation, growth factor signaling, cell cycling, apoptosis, and angiogenesis in HCC, a number of molecular target agents are under clinical trials. Sorafenib is the first systemic anticancer drug which has proven to gain survival benefit in the global as well as Asia-Pacific trials. However, the survival gain is still modest, and further efforts to improve outcomes in patients with HCC are necessary by developing novel drugs or combining other forms of therapies. This article will review signaling pathways in HCC and introduce molecular target agents under investigation currently.

RESUMO

BACKGROUND/AIMS: Transarterial chemoembolization (TACE) has long been used as a palliative therapy for unresectable hepatocellular carcinoma (HCC). High-dose hepatic arterial infusion chemotherapy (HAIC) has showed favorable outcomes in patients with intractable, advanced HCC. The aim of this study was to compare the effectiveness and safety of high-dose HAIC and conventional TACE using doxorubicin for advanced HCC. METHODS: The high-dose HAIC group comprised 36 patients who were enrolled prospectively from six institutions. The enrollment criteria were good liver function, main portal vein invasion (including vascular shunt), infiltrative type, bilobar involvement, and/or refractory to prior conventional treatment (TACE, radiofrequency ablation, or percutaneous ethanol injection), and documented progressive disease. Patients received 5-fluorouracil (500 mg/m(2) on days 1~3) and cisplatin (60 mg/m(2) on day 2 every 4 weeks) via an implantable port system. In the TACE group, 31 patients with characteristics similar to those in the high-dose HAIC group were recruited retrospectively from a single center. Patients underwent a transarterial infusion of doxorubicin every 4~8 weeks. RESULTS: Overall, 6 patients (8.9%) achieved a partial response and 20 patients (29.8%) had stable disease. The objective response rate (complete response+partial response) was significantly better in the high-dose HAIC group than in the TACE group (16.7% vs. 0%, P=0.030). Overall survival was longer in the high-dose HAIC group than in the TACE group (median survival, 193 vs. 119 days; P=0.026). There were no serious adverse effects in the high-dose HAIC group, while hepatic complications occurred more often in the TACE group. CONCLUSIONS: High-dose HAIC appears to improve the tumor response and survival outcome compared to conventional TACE using doxorubicin in patients with intractable, advanced HCC.

RESUMO

PURPOSE: Hepatic arterial infusion chemotherapy (HAIC) has been reported to be effective in patients with advanced hepatocellular carcinoma (HCC). METHODS: In this multicenter, prospective, open-labeled, clinical trial, we randomly assigned 68 patients with advanced HCC to receive either low-dose [n = 32, 5-fluorouracil (FU), 170 mg/m(2) and cisplatin, 7 mg/m(2) on days 1-5] or high-dose HAIC (n = 36, 5-FU, 500 mg/m(2) on days 1-3 and cisplatin, 60 mg/m(2) on day 2) every 4 weeks via an implantable port system. RESULTS: A total of 207 cycles of HAIC was given to the 68 patients. Overall, 6 patients (8.8%) achieved a partial response and 21 patients (30.9%) had stable disease. The objective response rate (CR + PR) was significantly improved in the high-dose group compared to the low-dose group (16.7% vs. 0%, P = 0.024). The median time to disease progression and overall survival were slightly prolonged in the high-dose group compared to the low-dose group (median survival, 193 vs. 153 days; P = 0.108; median time to disease progression, 145 vs. 90 days; P = 0.095). Multivariate analysis showed that tumor response to treatment [P = 0.007, RR 2.27 (95% CI, 1.248-4.132)] was the only factor associated with overall survival. All adverse events were tolerable and successfully managed in both treatment groups. CONCLUSIONS: Both HAIC regimens are safe and effective in patients with advanced HCC. High-dose HAIC achieves a better tumor response compared to low-dose HAIC.

RESUMO

Herbal remedies and health foods are widely used, and their side effects have been reported. We describe two cases of symptomatic toxic hepatitis that developed in middle-aged women after ingesting arrowroot juice. The clinical manifestations were nausea, vomiting, and jaundice. The diagnosis of toxic hepatitis was made using the Roussel Uclaf Causality Assessment Method score on the basis of the patient's history and laboratory data. After supportive care, the patients showed rapid improvements of clinical symptoms, laboratory findings, and liver stiffness. Clinicians should be aware that the consumption of arrowroot juice can cause toxic hepatitis.
