No evidence of association between inherited thrombophilia and increased risk of liver fibrosis.

BACKGROUND: Preliminary evidence suggests that inherited hypercoagulable disorders can lead to an increased risk of significant liver fibrosis. OBJECTIVE: We aimed to investigate the prevalence of significant fibrosis in patients with inherited thrombophilia, assessed by using liver stiffness (LS), and to compare this prevalence to that found in a large population-based cohort from the same region. METHODS: This was a single-center, cross-sectional study. A complete laboratory analysis for liver disease, LS by transient elastography and an abdominal ultrasound were performed in patients with inherited thrombophilia diagnosed between May 2013-February 2017. These patients were propensity score matched (ratio 1:4) with a population-based cohort from the same region (PREVHEP-ETHON study; NCT02749864; N = 5988). RESULTS: Of 241 patients with inherited thrombophilia, eight patients (3.3%) had significant fibrosis (LS ≥8 kPa). All of them had risk factors for liver disease and met diagnostic criteria for different liver diseases. After matching 221 patients with thrombophilia with 884 patients of the PREVHEP-ETHON cohort, the prevalence of significant fibrosis was similar between both cohorts (1.8% vs. 3.6%, p = 0.488). Multivariate analysis showed that age and liver disease risk factors, but not belonging to the thrombophilia cohort, were associated with the presence of significant fibrosis. The magnitude of the increased risk of significant fibrosis in patients with risk factors for liver disease was also similar in both cohorts. CONCLUSIONS: Our findings do not provide evidence supporting an association between inherited thrombophilia and an increased risk of significant liver fibrosis, independent of the presence of liver-related causes of fibrosis.

Risk of Recurrence of Hepatocarcinoma after Liver Transplantation: Performance of Recurrence Predictive Models in a Cohort of Transplant Patients.

Liver transplantation (LT) is a curative treatment for early-stage hepatocellular carcinoma (HCC) unsuitable for surgical resection. However, tumor recurrence (TR) rates range from 8% to 20% despite strict selection criteria. The validation of new prognostic tools, such as pre-MORAL or RETREAT risks, is necessary to improve recurrence prediction. A retrospective study was conducted at Marqués de Valdecilla University Hospital in Cantabria, Spain, between 2010 and 2019 to determine the rate of TR in LT patients and identify associated factors. Patients with liver-kidney transplantation, re-transplantation, HIV infection, survival less than 90 days, or incidental HCC were excluded. Data on demographic, liver disease-related, LT, and tumor-related variables, as well as follow-up records, including TR and death, were collected. TR was analyzed using the Log-Rank test, and a multivariate Cox regression analysis was performed. The study was approved by the IRB of Cantabria. TR occurred in 13.6% of LT patients (95% CI = 7.3-23.9), primarily as extrahepatic recurrence (67%) within the first 5 years (75%). Increased TR was significantly associated with higher Body Mass Index (BMI) (HR = 1.3 [95% CI = 1.1-1.5]), vascular micro-invasion (HR = 8.8 [1.6-48.0]), and medium (HR = 20.4 [3.0-140.4]) and high pre-MORAL risk (HR = 30.2 [1.6-568.6]). TR also showed a significant correlation with increased mortality. Conclusions: LT for HCC results in a 13.6% rate of tumor recurrence. Factors such as BMI, vascular micro-invasion, and medium/high pre-MORAL risk are strongly associated with TR following LT.

Portal Vein Thrombosis in the Setting of Cirrhosis: A Comprehensive Review.

Portal vein thrombosis constitutes the most common thrombotic event in patients with cirrhosis, with increased rates in the setting of advanced liver disease. Despite being a well-known complication of cirrhosis, the contribution of portal vein thrombosis to hepatic decompensation and overall mortality is still a matter of debate. The incorporation of direct oral anticoagulants and new radiological techniques for portal vein recanalization have expanded our therapeutic arsenal. However, the lack of large prospective observational studies and randomized trials explain the heterogenous diagnostic and therapeutic recommendations of current guidelines. This article seeks to make a comprehensive review of the pathophysiology, clinical features, diagnosis, and treatment of portal vein thrombosis in patients with cirrhosis.

Congestive Hepatopathy.

Liver disease resulting from heart failure (HF) has generally been referred as "cardiac hepatopathy". One of its main forms is congestive hepatopathy (CH), which results from passive venous congestion in the setting of chronic right-sided HF. The current spectrum of CH differs from earlier reports with HF, due to ischemic cardiomyopathy and congenital heart disease having surpassed rheumatic valvular disease. The chronic passive congestion leads to sinusoidal hypertension, centrilobular fibrosis, and ultimately, cirrhosis ("cardiac cirrhosis") and hepatocellular carcinoma after several decades of ongoing injury. Contrary to primary liver diseases, in CH, inflammation seems to play no role in the progression of liver fibrosis, bridging fibrosis occurs between central veins to produce a "reversed lobulation" pattern and the performance of non-invasive diagnostic tests of liver fibrosis is poor. Although the clinical picture and prognosis is usually dominated by the underlying heart condition, the improved long-term survival of cardiac patients due to advances in medical and surgical treatments are responsible for the increased number of liver complications in this setting. Eventually, liver disease could become as clinically relevant as cardiac disease and further complicate its management.

Microenvironment Eradication of Hepatitis C: A Novel Treatment Paradigm.

OBJECTIVES: Prisons are major reservoirs of hepatitis C virus (HCV) in which a therapeutic approach has been particularly difficult so far. Our aim was to create a permanent program of HCV elimination in a prison based on a "test and treat" strategy. METHODS: This open-label clinical trial was conducted in the Spanish prison "El Dueso" between May 2016 and July 2017. Viremic patients were treated with a ledipasvir-sofosbuvir regimen (8-12 weeks) according to the 2015 Spanish Guidelines. A teleconsultation program was established to follow-up patients from the hospital. Non-responders were submitted for a phylogenetic analysis and offered retreatment. An evaluation of new cases of HCV infection was performed every 6 months and upon release in all inmates. RESULTS: 847 (99.5%) inmates accepted to participate. HCV antibodies were present in 110 (13.0%) and 86 (10.2%) had detectable viremia. Most of them were genotype 1 or 3 (82.6%) and had

CT-guided fine-needle aspiration in vertebral osteomyelitis: true usefulness of a common practice.

Computed tomography (CT)-guided biopsy of the spine is considered a safe, accurate, and relatively inexpensive examination technique. Our purpose was to determine the diagnostic accuracy of CT-guided biopsies exclusively for vertebral osteomyelitis. A retrospective study was performed from a consecutive series of 72 patients with confirmed vertebral osteomyelitis with 46 CT-guided biopsies performed in 40 patients. Biopsy specimens were sent for bacteriologic and cytologic analysis. An adequate specimen for microbiologic examination was not obtained in one case and not enough sample for additional pathologic examination in 17 cases. The mean age of patients was 58 years, with a range of 1-88 years, including 24 men and 16 women. The level of spinal biopsy was thoracic in 18 (40%) and lumbar in 28 (60%). The analysis revealed the infection agent in 20 cases (43% sensitivity). Diagnostic rates obtained in patients with previous antibiotic treatment were significantly lower (23% vs. 60%, p = 0.013). Computed tomography-guided fine-needle aspiration biopsy is an important tool in the diagnostic evaluation of vertebral osteomyelitis. However, this technique yields a lower diagnostic rate than previously reported biopsy of neoplastic vertebral lesions, especially if performed in patients with previous antibiotic treatment.

Migrating intrathoracic gallstone: imaging findings.

We present the case of a 76-year-old man referred to our hospital with a round stone in central mediastinum and pneumomediastinum in chest radiography and computed tomography. He had a previous history of attempt of endoscopic retrievement of a gallstone that had caused a gastric outlet obstruction (Bouveret syndrome). To our knowledge, this is the first imaging description of mediastinal gallstone caused by esophagus perforation during complicated endoscopic lithotomy.

Necrotizing fasciitis secondary to diverticulitis.

Necrotizing fasciitis is a rare, rapidly progressive infectious process primarily involving the fascia and the subcutaneous tissue, with thrombosis of the cutaneous microcirculation. We present a case of necrotizing fasciitis secondary to diverticulitis in an immunosuppressed patient with rheumatoid arthritis.
