The Hepatologist in the Haematologist Field: a Rare Cause of Non-Cirrhotic Portal Hypertension

An 81 year-old gentleman was admitted to the emergency department of our hospital due to hematemesis and melena, and endoscopic evidence of portal hypertension. Due to presence of ascites and esophageal varices he was referred to gastroenterology care. His history included systemic mastocytosis, and biochemistry showed marked cholestasis with normal liver function tests. Clinical work-up was not consistent with liver disease-related portal hypertension, but rather hepatic involvement of systemic mastocytosis and the development of non-cirrhotic portal hypertension. This clinical case highlights that although systemic mastocytosis is uncommon, the subsequent development of liver involvement and non-cirrhotic portal hypertension are complications of the disease that need always be considere

Eradication of hepatitis C virus infection disclosing a previously hidden, underlying autoimmune hepatitis: Autoimmune hepatitis and HCV

Chronic hepatitis C virus (HCV) infection and autoimmune disorders show a complex interplay, with HCV often being identified as the trigger of autoimmune phenomena or diseases. While there is evidence of successful HCV treatment with direct-acting antivirals (DAA) in patients with concomitant HCV and autoimmune hepatitis (AIH), there are also sparse reports of AIH developing during, or following, DAA treatment. Here we report a case of a patient with suspected concomitant HCV and AIH who underwent liver biopsy but showed no histological hallmarks of autoimmunity. The patient later developed a hepatitic flare following DAA-induced viral clearance, and a second liver biopsy showed features compatible with AIH. Response to corticosteroid and azathioprine treatment was seen. This reports demonstrates that patients with features of auto-reactivity and HCV after DAA-induced viral clearance require careful follow-up.Chronic hepatitis C virus (HCV) infection and autoimmune disorders show a complex interplay, with HCV often being identified as the trigger of autoimmune phenomena or diseases.

Obeticholic Acid Improves Aminotransferases Early during Treatment in Patients with Primary Biliary Cholangitis Not Responding to Ursodeoxycholic Acid: A Study in Clinical Practice

Obeticholic acid (OCA) improves cholestasis and is generally well tolerated in patients with primary biliary cholangitis (PBC) not responding, or intolerant, to ursodeoxycholic acid (UDCA). As PBC is mainly a cholestatic disorder, less attention is paid to aminotransferase behavior in the course of treatment. In this study we evaluated, in clinical practice, the efficacy of OCA treatment on both alkaline phosphatase (ALP) and alanine aminotransferase (ALT) using updated healthy ranges for aminotransferases. Fifteen PBC patients, non-responders to UDCA, were evaluated at baseline and during OCA treatment with serial measurement of cholestasis indexes and ALT, that were also assessed using updated normal ranges (<30 IU/L in males, <19 IU/L in females). Median ALP and ALT decreased from 2.16 to 1.27 × upper limit of normal (p = 0.003) and from 0.93 to 0.78 × upper limit of normal (p = 0.008), respectively, in the course of OCA treatment. At treatment day-15, median ALT decreased by 29.7% and ALP by 8.8%. Bilirubin and albumin were unmodified throughout treatment. Using updated normal ranges, ALT levels were normal in 6.7% of patients at baseline and in 33.3% of patients at 18 months of treatment. OCA treatment improves cholestasis and, also, indexes of hepatocyte necrosis, with a decline in necro-inflammatory activity even predating the improvement in cholestasis. Use of recalibrated healthy ranges for aminotransferases might be a useful tool to assess hepatic histological activity and its improvement with OCA treatment

Early Tumor Shrinkage and Depth of Response Evaluation in Metastatic Pancreatic Cancer Treated with First Line Chemotherapy: An Observational Retrospective Cohort Study

Early tumor shrinkage (ETS) and depth of response (DoR) predict favorable outcomes in metastatic colorectal cancer. We aim to evaluate their prognostic role in metastatic pancreatic cancer (PC) patients treated with first-line modified-FOLFIRINOX (FOLFOXIRI) or Gemcitabine + Nab-paclitaxel (GemNab). Hence, 138 patients were tested for ETS, defined as a ≥20% reduction in the sum of target lesions’ longest diameters (SLD) after 6–8 weeks from baseline, and DoR, i.e., the maximum percentage shrinkage in the SLD from baseline. Association of ETS and DoR with progression-free survival (PFS) and overall survival (OS) was assessed. ETS was reached in 49 patients (39.5% in the FOLFOXIRI, 29.8% in the GemNab group; p = 0.280). In the overall population, ETS was significantly associated with better PFS (8.0 vs. 4.8 months, p < 0.001) and OS (13.2 vs. 9.7 months, p = 0.001). Median DoR was −27.5% (−29.4% with FOLFOXIRI and −21.4% with GemNab, p = 0.016): DoR was significantly associated with better PFS (9.0 vs. 6.7 months, p < 0.001) and OS (14.3 vs. 11.1 months, p = 0.031). Multivariate analysis confirmed both ETS and DoR are independently associated with PFS and OS. In conclusion, our study added evidence on the role of ETS and DoR in the prediction of outcome of PC patients treated with first-line combination chemotherapy

Material deprivation affects the management and clinical outcome of hepatocellular carcinoma in a high-resource environment

Aim: This study investigated how material deprivation in Italy influences the stage of hepatocellular carcinoma (HCC) at diagnosis and the chance of cure. Methods: 4114 patients from the Italian Liver Cancer database consecutively diagnosed with HCC between January 2008 and December 2018 were analysed about severe material depriva- tion (SMD) rate tertiles of the region of birth and region of managing hospitals, according to the European Statistics on Income and Living Conditions. The main outcomes were HCC diagnosis modalities (during or outside surveillance), treatment adoption and overall survival. Results: In more deprived regions, HCC was more frequently diagnosed during surveillance, while the incidental diagnosis was prevalent in the least deprived. Tumour characteristics did not differ among regions. The proportion of patients undergoing potentially curative treat- ments progressively decreased as the SMD worsened. Consequently, overall survival was bet- ter in less deprived regions. Patients who moved from most deprived to less deprived regions increased their probability of receiving potentially curative treatments by 1.11 times (95% CI 1.03 to 1.19), decreasing their mortality likelihood (hazard ratio 0.78 95% CI 0.67 to 0.90). Conclusions: Socioeconomic status measured through SMD does not seem to influence HCC features at diagnosis but brings a negative effect on the chance of receiving potentially curative treatments. Patient mobility from the most deprived to the less deprived regions increased the access to curative therapies, with the ultimate result of improving survival

Recalibrating survival prediction among patients receiving trans\u2010arterial chemoembolization for hepatocellular carcinoma

Background & Aims The Pre-TACE-Predict model was devised to assess prognosis of patients treated with trans-arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). However, before entering clinical practice, a model should demonstrate that it performs a useful role. Methods We performed an independent external validation of the Pre-TACE model in a cohort that differs in setting and time period from the one that generated the original model. Data from 826 patients treated with TACE for naïve HCC (2008-2018) were used to assess calibration and discrimination of the Pre-TACE-Predict model. Results The four risk-categories identified by the Pre-TACE-Predict model had gradient monotonicity, with median survivals of 52.0, 36.2, 29.9, and 14.1 months respectively. However, predicted survivals systematically underestimated observed survivals (R2: 0.667). A recalibration was adopted maintaining fixed the prognostic index and modifying the baseline survival function. This resulted in an almost perfect calibration (R2: 0.995) in all the four risk categories. Cox regressions showed that aetiology and macrovascular invasion, included in the Pre-TACE-Predict model, had no prognostic impact in the present study population, and that coefficients for tumour size and multiplicity were overestimated. The c-index was similar to that of the m-HAP-III, but higher than those of HAP, m-HAP-II and the six-and-twelve models. Conclusions The recalibration of Pre-TACE-Predict model improved the estimation of survival probabilities of HCC patients treated with TACE. The highest discriminatory ability of the Pre-TACE-model in comparison to other available models, together with risk stratification and recalibration, makes it the best prognostic tool currently available for these patients
