Clinical outcomes of coronavirus disease 2019 in patients with pre-existing liver diseases: A multicenter study in South Korea.

BACKGROUND/AIMS: Although coronavirus disease 2019 (COVID-19) has spread rapidly worldwide, the implication of pre-existing liver disease on the outcome of COVID-19 remains unresolved.
. METHODS: A total of 1,005 patients who were admitted to five tertiary hospitals in South Korea with laboratory-confirmed COVID-19 were included in this study. Clinical outcomes in COVID-19 patients with coexisting liver disease as well as the predictors of disease severity and mortality of COVID-19 were assessed.
. RESULTS: Of the 47 patients (4.7%) who had liver-related comorbidities, 14 patients (1.4%) had liver cirrhosis. Liver cirrhosis was more common in COVID-19 patients with severe pneumonia than in those with non-severe pneumonia (4.5% vs. 0.9%, P=0.006). Compared to patients without liver cirrhosis, a higher proportion of patients with liver cirrhosis required oxygen therapy; were admitted to the intensive care unit; had septic shock, acute respiratory distress syndrome, or acute kidney injury; and died (P<0.05). The overall survival rate was significantly lower in patients with liver cirrhosis than in those without liver cirrhosis (log-rank test, P=0.003). Along with old age and diabetes, the presence of liver cirrhosis was found to be an independent predictor of severe disease (odds ratio, 4.52; 95% confidence interval [CI], 1.20-17.02;P=0.026) and death (hazard ratio, 2.86; 95% CI, 1.04-9.30; P=0.042) in COVID-19 patients.
. CONCLUSION: This study suggests liver cirrhosis is a significant risk factor for COVID-19. Stronger personal protection and more intensive treatment for COVID-19 are recommended in these patients.

Successful Treatment of Combined Aspergillus and Cytomegalovirus Abscess in Brain and Lung After Liver Transplant for Toxic Fulminant Hepatitis.

Invasive aspergillosis is one of the most important and fatal complications after liver transplant, especially in patients with involvement of the central nervous system. We present a case of a patient who developed cerebral and pulmonary aspergillosis, coinfected with cytomegalovirus, after liver transplant for toxic fulminant hepatitis. The patient was treated successfully with neurosurgical intervention and voriconazole. Voriconazole is considered more effective in cerebral aspergillosis than other anti-fungal agents due to the greater penetration into central nervous system and higher cerebrospinal fluid and brain tissue levels.

Survival outcomes of hepatic resection compared with transarterial chemoembolization or sorafenib for hepatocellular carcinoma with portal vein tumor thrombosis.

BACKGROUND/AIMS: Treating hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) remains controversial. We compared the outcomes of hepatic resection (HR), transarterial chemoembolization (TACE), and sorafenib therapy as treatments for HCC with PVTT. METHODS: Patients diagnosed as HCC with PVTT between January 2000 and December 2011 who received treatment with sorafenib, HR, or TACE were included. Patients with main PVTT, superior mesenteric vein tumor thrombosis, or Child-Turcotte-Pugh (CTP) class C were excluded. The records of 172 patients were analyzed retrospectively. HR, TACE, and sorafenib treatment were performed is 40, 80, and 52 patients respectively. PVTT was classified as either involving the segmental branch (type I) or extending to involve the right or left portal vein (type II). RESULTS: The median survival time was significantly longer in the HR group (19.9 months) than in the TACE and sorafenib groups (6.6 and 6.2 months, respectively; both p<0.001), and did not differ significantly between the latter two groups (p=0.698). Among patients with CTP class A, type I PVTT or unilobar-involved HCC, the median survival time was longer in the HR group than in the TACE and sorafenib groups (p=0.006). In univariate analyses, the initial treatment method, tumor size, PVTT type, involved lobe, CTP class, and presence of cirrhosis or ascites were correlated with overall survival. The significant prognostic factors for overall survival in Cox proportional-hazards regression analysis were initial treatment method (HR vs. TACE: hazard ratio=1.750, p=0.036; HR vs. sorafenib: hazard ratio=2.262, p=0.006), involved lobe (hazard ratio=1.705, p=0.008), PVTT type (hazard ratio=1.617, p=0.013), and CTP class (hazard ratio=1.712, p=0.012). CONCLUSIONS: Compared with TACE or sorafenib, HR may prolong the survival of patients with HCC in cases of CTP class A, type I PVTT or unilobar-involved HCC.

Efficacy and safety of human placental extract for alcoholic and nonalcoholic steatohepatitis: an open-label, randomized, comparative study.

Human placental extract (HPE) is a traditional medicine that has been used for the symptomatic treatment of liver disease without any verifying clinical evidence. This study aimed to evaluate the efficacy and safety of HPE in patients with alcoholic or nonalcoholic steatohepatitis (ASH or NASH). We designed this clinical trial as a multicenter, open-label, randomized, comparative noninferiority study to improve the reliability of analyses. The enrollment criteria were limited to ASH or NASH patients with serum alanine aminotransferase (ALT) 1.5-fold higher than the normal level. Patients in the control group were treated with a commercially available mixture of liver extract and flavin adenine dinucleotide (LE­FAD). Intention-to-treat (ITT) analysis was applied to 194 patients, and per-protocol (PP) analysis was available for 154 patients. The rate of primary goal achievement of treatment efficacy was arbitrarily defined as 20% or greater improvement in ALT level compared with the pretreatment level and did not differ significantly between the HPE and control groups [62.9% (44/70) vs. 48.8% (41/84); p=0.0772]. ITT and modified ITT analysis showed results similar to those of PP analysis. Adverse drug reactions (ADRs) of minimal to moderate degree occurred in 3.1% of patients. The ADR and treatment compliance rates were similar in both groups. In conclusion, the clinical value of HPE in the treatment of ASH and NASH is equivalent to that of LE­FAD.

A comparative study of high-dose hepatic arterial infusion chemotherapy and transarterial chemoembolization using doxorubicin for intractable, advanced hepatocellular carcinoma.

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.

A randomized comparative study of high-dose and low-dose hepatic arterial infusion chemotherapy for intractable, advanced hepatocellular carcinoma.

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.

[Incidence and risk factors of acute hepatic failure after transcatheter arterial chemoembolization for hepatocellular carcinoma].

BACKGROUND/AIMS: Although transcatheter arterial chemoembolization (TACE) is a major treatment modality for unresectable hepatocellular carcinoma (HCC), acute hepatic failure after TACE is not rare. However, reports dealing with this important complication are not good enough and results are often variable. The purpose of this study was to evaluate the incidence and associated risk factors of acute hepatic failure after TACE. METHODS: From January 2001 to November 2004, six hundred and thirty-two TACE sessions were performed in 377 patients (294 men and 83 women). Adriamycin mixed lipiodol solution and gelfoam were used for TACE. Various clinical and radiological factors before and after the procedure were reviewed retrospectively. Univariate and multivariate analyses were performed to evaluate the risk factors associated with the development of acute hepatic failure after TACE. RESULTS: Acute hepatic failure occurred in 76 (12.0%) of the 632 TACE sessions within 14 days. Univariate analysis revealed that Child-Pugh class, 1st TACE, total bilirubin level, number of involved segments, total size of tumor, presence of right portal vein thrombosis (PVT) or main PVT, involvement of segment 1, 5, 6, 7, modified UICC stage, and doses of chemotherapeutic agent were significantly different between the patients with or without hepatic failure after TACE. Among them, elevated total bilirubin (p=0.001, E (beta)=1.449), presence of right (p=0.035, E (beta)=2.109) or main (p=0.011, E (beta)=4.067) PVT were independently associated factors in multivariate analysis. CONCLUSIONS: The incidence of acute hepatic failure after TACE was 12.0%. Elevated bilirubin level and portal vein thrombosis could be considered as the predictive factors for acute hepatic failure after TACE in HCC patients.
