Serum levels of anti-heat shock protein 27 antibodies in patients with chronic liver disease.

Serum levels of anti-heat shock protein 27 antibodies in patients with chronic liver disease. Cell Stress Chaperones. 2020 Sep 07;: Authors: Gruden G, Carucci P, Barutta F, Burt D, Ferro A, Rolle E, Pinach S, Abate ML, Campra D, Durazzo M Abstract Heat shock protein 27 (HSP27), an intracellular molecular chaperone, is involved in the pathogenesis of cancer by promoting both tumor cell proliferation and resistance to therapy. HSP27 is also present in the circulation and circulating HSP27 (sHSP27) can elicit an autoimmune response with production of antibodies. Levels of sHSP27 are enhanced in patients with hepatocellular carcinoma (HCC); it is, however, unknown whether changes in HSP27 antibody levels occur in patients with HCC and can be exploited as a circulating biomarker of HCC. Our aim was to assess the potential association between newly diagnosed HCC and serum anti-HSP27 antibody levels. In this cross-sectional study, anti-HSP27 antibody levels were measured in serum samples from 71 HCC patients, 80 subjects with chronic liver disease, and 38 control subjects by immunoenzymatic assay. Anti-HSP27 antibody levels did not differ significantly among groups. However, in patients with chronic active hepatitis/cirrhosis, anti-HSP27 levels were significantly higher in subjects with a positive history of alcoholism (p = 0.03). Our data do not support the hypothesis that anti-HSP27 antibody levels may help identify patients with HCC among subje...

Authors: Musio F Abstract INTRODUCTION: Anemia has and will continue to be a central theme in medicine particularly as clinicians are treating a burgeoning population of complex multi-organ system processes. As a result of multiple randomized controlled trials (RCTs), meta-analyses, and societal recommendations overly restrictive paradigms and under-administration of erythropoiesis stimulating agents (ESAs) have likely been followed by clinicians among all specialties. AREAS COVERED: A review of anemia in the context of chronic kidney disease, hematologic malignancies and cancer is presented with focus on the e...

Conclusions: While there is a certain overlap between the results of the current study and published transcriptomic profiles of non-transplanted livers with steatosis, we have identified discrete characteristics of the non-alcoholic fatty liver disease in liver grafts potentially utilizable for the establishment of predictive signature. Introduction Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in industrialized countries, its prevalence being estimated at 19–31.3% (1). It encompasses a range of conditions that are thought to arise from fatty liver (simple steatosis) throu...

ConclusionsWhen the liver diseases advance to cirrhosis, the incidence of HCC is markedly increased. The development of HCC must be closely monitored by ultrasonography, magnetic resonance imaging, and computed tomography, irrespective of the different kinds of liver diseases.

CONCLUSIONS: The liver-specific miRs can be used as rapid and non-invasive biomarkers of hepatitis to discern different stages of hepatitis. Blocking or stimulating pathways associated with miR regulation in liver could unveil novel therapeutic strategies in the management of liver diseases.

The incidence of hepatocellular carcinoma in the United States has grown steadily during the past 2 decades and the associated mortality has increased proportionally. In 2012, there were an estimated 30 000 new cases of liver cancer and 24 000 liver cancer–associated deaths. Underlying liver disease associated with hepatitis, autoimmune disorders, alcoholic cirrhosis, or nonalcoholic fatty liver disease has become the major risk factor for hepatocellular carcinoma in the United States. In fact, liver dysfunction in some form is found in upwards of 90% of patients who present with hepatocellular carcinoma. In thes...
