ABSTRACT

An arterioenteric fistula is a devastating and life-threatening condition. As patients often present in extremis from hemorrhage shock, an early diagnosis and prompt life-saving interventions have to be performed. In this report, we describe a case of a 38-year-old Japanese woman who presented with hematochezia that rapidly progressed to hemorrhagic shock secondary to an iliac artery-enteric fistula that developed during bevacizumab-containing chemotherapy for recurrent cervical cancer. The patient underwent successful endovascular treatment with a covered stent-graft as a bridge to definitive open surgery.

ABSTRACT

Background/Aims: Acute cholangitis (AC) is a potentially life-threatening bacterial infection, and timely antimicrobial treatment, faster than that achieved with bacterial cultures, is recommended. Although the current guidelines refer to empirical antimicrobial treatment, various kinds of antimicrobial agents have been cited because of insufficient analyses on the spectrum of pathogens in AC. Enterococcus spp. is one of the most frequently isolated Gram-positive bacteria from the bile of patients with AC, but its risk factors have not been extensively studied. This study aimed to analyze the risk factors of AC caused by Enterococcus faecalis and Enterococcus faecium. Methods: Patients with AC who were hospitalized in a Japanese tertiary center between 2010 and 2015 were retrospectively analyzed. Patients' first AC episodes in the hospital were evaluated. Results: A total of 266 patients with AC were identified. E. faecalis and/or E. faecium was isolated in 56 (21%) episodes of AC. Prior endoscopic sphincterotomy (EST), the presence of a biliary stent, prior cholecystectomy, and past intensive care unit admission were more frequently observed in AC patients with E. faecalis and/or E. faecium than in those without such bacteria. Prior EST was identified as an independent risk factor for AC caused by E. faecalis and/or E. faecium in the multivariate analysis. Conclusions: Given the intrinsic resistance of E. faecalis and E. faecium to antibiotics, clinicians should consider empirical therapy with anti-enterococcal antibiotics for patients with prior EST.

ABSTRACT

Background/Aims: Empiric antibiotics are given in combination with biliary drainage for acute cholangitis but sometimes turn out to be insensitive to microorganisms in blood and bile. Clinical outcomes were compared according to sensitivity to microorganisms detected in blood and bile culture to evaluate the impact of sensitivity to empiric antibiotics in cholangitis. Methods: Consecutive patients who underwent biliary drainage for acute cholangitis were retrospectively studied. Clinical outcomes such as 30-day mortality, length of hospital stay and high care unit stay, organ dysfunction and duration of fever were compared in three groups: group A (sensitive to both blood and bile culture), group B (sensitive to blood culture alone) and group C (insensitive to both blood and bile culture). Results: Eighty episodes of cholangitis were classified according to sensitivity results: 42, 32 and six in groups A, B and C. Escherichia coli and Klebsiella were two major pathogens. There were no significant differences in 30-day mortality rate (7%, 0%, and 0%, p=0.244), length of hospital stay (28.5, 21.0, and 20.5 days, p=0.369), organ dysfunction rate (14%, 25%, and 17%, p=0.500), duration of fever (4.3, 3.2, and 3.5 days, p=0.921) and length of high care unit stay (1.4, 1.2, and 1.7 days, p=0.070) in groups A, B and C. Empiric antibiotics were changed in 11 episodes but clinical outcomes appeared to be non-inferior even in 31 episodes of cholangitis who were on inadequate antibiotics throughout the course. Conclusions: Sensitivity of empiric antibiotics was not associated with clinical outcomes in acute cholangitis.

ABSTRACT

INTRODUCTION: Transcatheter arterial chemoembolization (TACE) is the first-line treatment for intermediate stage hepatocellular carcinoma (HCC) and prolongs survival in HCC patients. However, repeated TACE results in diminished therapeutic response. In addition, the superiority of sorafenib to TACE monotherapy or combined therapy in patients with HCC is still controversial. The prognosis of HCC has many variables and, thus, the effect of a specific treatment is difficult to evaluate. The frequency of treatments per year (FT rate) used in this study was obtained by dividing the total number of radiofrequency ablations and TACE or transcatheter arterial infusion treatments by the years of survival. The aim of this study was to evaluate the overall survival (OS) of TACE versus sorafenib using the FT rate. METHODS: We compared the OS of patients with recurrence of HCC receiving repeated TACE monotherapy (CON) with those receiving therapy switched from TACE to sorafenib (SOR). In addition, a one-to-one FT rate matching cohort consisting of matched SOR (mSOR) and matched CON (mCON) was determined using the propensity score matching method, and OS in the cohort was evaluated. Factors influencing survival were evaluated using Cox proportional hazard regression analysis in all patients and the FT rate matched cohort. RESULTS: In the FT rate matched cohort, the cumulative survival rate was significantly higher in the mSOR group compared with the mCON group. Multivariate regression analysis of the FT rate matched cohort showed the FT rate and sorafenib to be significant variables for survival with a hazard ratio (HR) of 2.86 (p < 0.001) and 0.42 (p = 0.008), respectively. CONCLUSION: Early switching from TACE to sorafenib therapy may prolong OS in HCC patients unresponsive to TACE. The present study indicates that the FT rate is potentially a useful index in evaluating the outcome for patients at various stages and treatment regimens. FUNDING: Bayer Yakuhin, Ltd.

ABSTRACT

BACKGROUND AND OBJECTIVE: After tolvaptan was approved for the treatment of cirrhosis patients with ascites, only a few studies have reported its efficacy in the real clinical setting, and no studies have reported its contribution to overall survival. This study clarified the clinical outcomes of tolvaptan treatment in terms of improving ascites unresponsive to standard diuretics (AUS) and overall survival. METHODS: We retrospectively enrolled 80 decompensated cirrhosis patients with AUS who were administered tolvaptan from October 2012 to December 2014. The patients were divided into two groups according to ascites improvement. We compared laboratory results and overall survival and analyzed factors that affected overall survival. RESULTS: Of the 80 patients, 59 (73.8 %) were male and the median age was 70 years. Thirty-nine (48.8 %) patients were Child-Pugh class C, and 36 (45.0 %) had advanced hepatocellular carcinoma (HCC). Tolvaptan was effective in 48 (60.0 %) patients with an average 3.8 kg weight reduction and ineffective in 32 (40.0 %) patients. The cumulative survival rate differed significantly between the two groups (p < 0.0001), with 87.5 and 68.0 % survival at 30 and 90 days, respectively, in the effective group, and 50.0 and 30.5 % survival, respectively, in the ineffective group. Multivariate analysis showed that improvement in AUS, advanced HCC, total bilirubin level, blood urea nitrogen level, and the presence of hyponatremia were independent predictors of overall survival. CONCLUSIONS: Tolvaptan could possibly improve overall survival in decompensated cirrhosis patients with AUS as long as it was demonstrated to be effective in these patients.
