RESUMO

INTRODUCTION AND AIM: Thrombosis is a vascular disorder of the liver often associated with significant morbidity and mortality. Cirrhosis is a predisposing factor for portal venous system thrombosis. The aim of this study is to determine differences between cirrhotics and non-cirrhotics that develop thrombosis in portal venous system and to evaluate if cirrhosis severity is related to the development of portal venous system thrombosis. MATERIAL AND METHODS: We studied patients diagnosed with portal venous system thrombosis using contrast-enhanced computed tomography scan and doppler ultrasound at Medica Sur Hospital from 2012 to 2017. They were categorized into two groups; cirrhotics and non-cirrhotics. We assessed the hepatic function by Child-Pugh score and model for end-stage liver disease. RESULTS: 67 patients with portal venous system thrombosis (25 with non-cirrhotic liver and 42 with cirrhosis) were included. The mean age (± SD) was 65 ± 9.5 years in cirrhotic group and 57 ± 13.2 years (p = 0.009) in non-cirrhotic group. Comparing non-cirrhotics and cirrhotics, 8 non-cirrhotic patients showed evidence of extra-hepatic inflammatory conditions, while in the cirrhotic group no inflammatory conditions were found (p < 0.001). 27 (64.29%) cirrhotic patients had thrombosis in the portal vein, while only 9 cases (36%) were found in non-cirrhotics (p = 0.02). CONCLUSIONS: In cirrhotic patients, hepatocellular carcinoma and cirrhosis were the strongest risk factors to develop portal venous system thrombosis. In contrast, extrahepatic inflammatory conditions were main risk factors associated in non-cirrhotics. Moreover, the portal vein was the most frequent site of thrombosis in both groups.

RESUMO

Long thought to be hypocoagulable, new evidence suggests cirrhosis patients have "rebalanced" coagulation in the setting of decreased synthesis of both pro- and anti-coagulant factors. Traditional testing like PT/INR reflects only the decreased synthesis of pro-coagulant factors and thus does not correspond to bleeding or clotting risk in this population. In this review, we discuss the use of viscoelastic testing (VET), an assay of global hemostasis in cirrhosis patients. We describe the technique and interpretation of commercially available VET and assess the application of VET in both transplant and non-transplant cirrhosis populations. VET largely correlates well with traditional testing including platelet count and fibrinogen level, however, is potentially less accurate in patients with low fibrinogen levels. VET may be useful in identifying patients at higher risk of hypercoagulable complications post-transplant and reflects changes in hemostasis in decompensated patients. While VET has been associated with decreased transfusión support in multiple studies, the lack of bleeding in patients who avoided prophylactic transfusion suggests a "rescue" rather than prophylactic approach to transfusion may be ideal and further studies with a "rescue" arm are needed. Additional prospective studies of VET should include clinically relevant endpoints of bleeding and thrombosis.

RESUMO

INTRODUCTION: Type-1 hepatorenal syndrome (HRS-1) portends a poor prognosis in patients with cirrhosis. Currently available medical therapies are largely ineffective, save for liver transplantation. We aimed to determine if pentoxifylline (PTX) therapy in addition to the standard of care of volume expansion with albumin and vasoconstriction with midodrine and octreotide (AMO) is safe and efficacious compared to AMO in HRS-1 treatment. MATERIAL AND METHODS: Hospitalized subjects with decompensated cirrhosis and HRS-1 were enrolled. PTX or placebo was administered with AMO therapy for up to 14 days. The primary endpoint was HRS-1 resolution (serum creatinine ≤ 1.5 g/dL for > 24 h). Secondary endpoints were change in creatinine and MELD score, partial treatment response, 30-and 180-day overall and transplant free survival. RESULTS: Twelve subjects with mean age 58.9 ± 6.2 years were enrolled and randomized. Mean MELD score was 26.5 ± 7.4 and 58.3% were male. Overall cohort 30- and 180-day survival was 58.3% and 33.3% respectively. Two subjects underwent liver transplantation. HRS-1 resolution (16.7% vs. 16.7%, p = 1.000), partial treatment response (33.3% vs. 16.7%, p = 0.505), change in creatinine (+0.48 g/dL, 95% CI -0.49-1.46 vs. +0.03 g/dL, 95% CI -0.64- 0.70, p = 0.427), 30-day survival (66.6% vs. 50.0%, p = 0.558) and 180-day survival (50.0% vs. 16.7%, p = 0.221) were similar between the two groups. Serious adverse events necessitating treatment discontinuation were rare (n = 1, PTX). DISCUSSION: The addition of PTX to AMO in the treatment of HRS-1 is safe when compared to the current standard of care. Future large-scale prospective study to validate the efficacy of this treatment seems warranted.

RESUMO

ABSTRACT Introduction and aim. The effect of the new direct acting antiviral drugs (DAAs) for chronic hepatitis C (HCV) on glycemic control is unknown. Materials and methods. We conducted a retrospective cohort study of patients who were treated for chronic HCV with direct-acting antiviral medications at a single academic institution between May 2013 and April 2016. Univariate analysis was performed comparing subjects pre- and post-treatment. Results. One hundred seventy-five consecutive adult patients were treated for chronic HCV and met enrollment criteria. The majority (80.8%) were genotype 1 and overall cohort sustained virologic response at week 12 (SVR12) was 97.8%. Thirty-one (18.5%) had diabetes mellitus (DM); twenty-six had pre- and post-treatment HbA1c values. Of these, 76.9% were male and 61.5% had cirrhosis. Ninety-six percent were prescribed sofosbuvir-based therapy and all but one (96.8%) achieved SVR12. Three patients were started on treatment despite meeting the definition for poorly controlled DM (HbA1c > 9 mg/dL). There was no significant difference when comparing pre-treatment (7.36 mg/dL, 95% CI 6.55-8.16) to post-treatment HbA1c (7.11 mg/dL, 95% CI 6.34-7.88, p = 0.268). Thirty-one percent of subjects required dose escalation or the initiation of insulin based therapy during treatment. Discussion. Although chronic HCV is associated with exacerbation of insulin resistance, our results showed HbA1c to be unaffected by eradication of chronic HCV with DAA in diabetic patients with and without cirrhosis. Paradoxically, almost 1/3 of patients required escalation of anti-diabetic therapy during treatment. Long-term studies are warranted to understand the relationship between HCV viral eradication and insulin metabolism.(AU)

RESUMO

ABSTRACT Introduction. The aim of this study is to investigate large volume therapeutic paracentesis using either a z-tract or axial (coxial) technique in a randomized controlled trial. Materials and methods. In this randomized, single blind study, patients with cirrhosis undergoing outpatient therapeutic paracentesis were randomized to the z-tract or the modified angular (coaxial) needle insertion technique. Subject and procedure characteristics were compared between the groups with ascites leakage as quantified by need for dressing changes with standardized sized gauze pads as a primary endpoint and subject procedural discomfort, operator preference, and procedure complications as secondary endpoints. Results. 72 paracenteses were performed during the study period: 34 to the z-tract and 38 to the coaxial insertion technique. Following exclusions, a total of 61 paracenteses were analyzed: 30 using the z-tract technique and 31 using the coaxial technique. There were equal rates of post-procedural leakage of ascites between groups (13% in both groups, p = 1.00). Using the visual analog scale (0 - 100), there was a statistically significant increase in the subject reported pain score with the z-tract compared with the coaxial method [26.4 (95% CI 18.7 - 34.1) vs. 17.2 (95% CI 10.6 - 23.8), p = 0.04]. Mean physician rated procedure difficulty (1 - 5) was significantly higher for the z-tract vs. the coaxial technique [2.1 (95% CI 1.6 - 2.6) vs. 1.5 (95% CI 1.2 - 1.8), p = 0.04]. Conclusion. When compared to the z-tract technique, the coaxial insertion technique is superior during large volume paracentesis in cirrhosis patients.
