RESUMEN
BACKGROUND: The ratio of von Willebrand Factor to platelets (VITRO) reflects the severity of fibrosis and portal hypertension and might thus hold prognostic value. METHODS: Patients with compensated cirrhosis were recruited. VITRO, Child-Pugh score (CPS) and MELD were determined at study entry. Hepatic decompensation was defined as variceal bleeding, ascites or hepatic encephalopathy. Liver transplantation and death were recorded. RESULTS: One hundred and ninety-four patients with compensated cirrhosis (CPS-A 89%, B 11%; 56% male; median age 56 years; 50% with varices) were included. During a median follow-up of 45 months (IQR 29-61), decompensation occurred in 35 (18%) patients and 14 (7%) patients deceased. The risk of hepatic decompensation was significantly increased in the n = 88 (45%) patients with a VITRO ≥ 2.5 (p < 0.001). Patients with a VITRO ≥ 2.5 had a higher probability of decompensation at 1-year 9% (95% CI 3-16) vs. 0% (95% CI 0-0) and at 2-years 18% (95% CI 10-27%), vs. 4% (95% CI 0-8%) as compared to patients with VITRO < 2.5. Patients with VITRO ≥ 2.5, the estimated 1-year/2-year survival rates were at 98% (95% CI 95-100%) and 94% (95% CI 88-99%) as compared to 100% (95% CI 100-100%) both in the patients with a VITRO < 2.5 (p < 0.001). After adjusting for age, albumin and MELD, VITRO ≥ 2.5 remained as significant predictor of transplant-free mortality (HR 1.38, CI 1.09-1.76; p = 0.007). Patients with compensated cirrhosis and VITRO > 2.1 after hepatitis C eradication remained at significantly increased risk for decompensation (p = 0.033). CONCLUSIONS: VITRO is a valuable prognostic tool for estimating the risk of decompensation and mortality in patients with compensated cirrhosis-including the setting after hepatitis C eradication.

The Billroth III guidelines were developed during a consensus meeting of the Austrian Society of Gastroenterology and Hepatology (ÖGGH) and the Austrian Society of Interventional Radiology (ÖGIR) held on 18 February 2017 in Vienna. Based on international guidelines and considering recent landmark studies, the Billroth III recommendations aim to help physicians in guiding diagnostic and therapeutic strategies in patients with portal hypertension.

BACKGROUND: Treatment of chronic hepatitis C virus (HCV) infection was revolutionized within the last years. Interferon free antiviral regimens are not accessible without limitations. Combination of peginterferon/ribavirin with first generation direct acting antivirals is less effective and associated with serious adverse events. AIM: We have shown that vWF-Ag is associated with portal hypertension and treatment response to PEG/RBV and we evaluated if vWF-Ag is a predictive marker for treatment response and safety in patients with triple therapy. METHODS: 222 HCV-GT 1 patients and DAA based triple therapy were included in this retrospective, multicenter study. RESULTS: Median vWF-Ag levels were 167.0% [IQR: 124.0-210.0%]. Significantly higher levels were seen in patients without SVR; median 190% [IQR: 146.0-259.5%] versus SVR: 142.5% [IQR: 114.3-196.8%], p<0.001. Furthermore levels of vWF-Ag were identified as independent predictor of non SVR; (OR: 1.009; 95%CI: 1.016-1.3, p=0.005). In patients with cirrhosis elevated vWF-Ag levels were associated with increased incidence of SAEs (OR: 1.016; 95%CI: 1.004-1.028; p=0.007). Best cut off for prediction of SAEs was vWF-Ag>281.5% with a sensitivity of 78% and a specificity of 90%. CONCLUSION: Baseline vWF-Ag levels predict outcome of DAA based treatment in HCV-1 patients and identify patients with a risk of SAEs. Therefore vWF-Ag may be an additional marker for selecting patients for interferon free therapeutic regimens.

BACKGROUND: Clinically significant portal hypertension (CSPH), defined as hepatic venous pressure gradient (HVPG) ≥10 mmHg, causes major complications. HVPG is not always available, so a non-invasive tool to diagnose CSPH would be useful. VWF-Ag can be used to diagnose. Using the VITRO score (the VWF-Ag/platelet ratio) instead of VWF-Ag itself improves the diagnostic accuracy of detecting cirrhosis/ fibrosis in HCV patients. AIM: This study tested the diagnostic accuracy of VITRO score detecting CSPH compared to HVPG measurement. METHODS: All patients underwent HVPG testing and were categorised as CSPH or no CSPH. The following patient data were determined: CPS, D'Amico stage, VITRO score, APRI and transient elastography (TE). RESULTS: The analysis included 236 patients; 170 (72%) were male, and the median age was 57.9 (35.2-76.3; 95% CI). Disease aetiology included ALD (39.4%), HCV (23.4%), NASH (12.3%), other (8.1%) and unknown (11.9%). The CPS showed 140 patients (59.3%) with CPS A; 56 (23.7%) with CPS B; and 18 (7.6%) with CPS C. 136 patients (57.6%) had compensated and 100 (42.4%) had decompensated cirrhosis; 83.9% had HVPG ≥10 mmHg. The VWF-Ag and the VITRO score increased significantly with worsening HVPG categories (P<0.0001). ROC analysis was performed for the detection of CSPH and showed AUC values of 0.92 for TE, 0.86 for VITRO score, 0.79 for VWF-Ag, 0.68 for ELF and 0.62 for APRI. CONCLUSION: The VITRO score is an easy way to diagnose CSPH independently of CPS in routine clinical work and may improve the management of patients with cirrhosis.

UNLABELLED: Health professionals from Zambia and Austria conducted a low-cost intervention in Lusaka, Zambia, intended to improve care outcomes for victims of interpersonal violence (IPEV). It was designed to build on existing health and social services infrastructures. During 1â year, 174 victims of IPEV seen at the Lusaka University Hospital emergency room were interviewed by medical students. An intervention included training for medical and social service personnel and distribution at key locations of printed materials on services available to IPEV victims. Postintervention data analysis revealed that victims of IPEV had improved understanding of available social services, and victims' confidence was increased about receiving additional help and articulating health concerns. Other benefits: improved visibility, networking among partner organisations; new descriptive data about IPEV victims; improved cross-cultural understanding among medical participants. RECOMMENDATION: low-cost interventions should continue to be explored to improve care for victims of IPEV in resource-poor settings.
