Abstract
BACKGROUND Studies on the serum concentration of hyaluronic acid (HA) in newly diagnosed patients with acute myeloid leukemia (AML), B-acute lymphoblastic leukemia (B-ALL), and mantle-cell lymphoma (MCL) are scarce. In this study, we focused on investigating whether HA could serve as a possible prognostic marker in patients with AML, B-ALL, and MCL. METHODS The serum concentration of HA was measured in a total of 51 patients with newly diagnosed AML, B-ALL, and MCL. Venous blood was collected 1 day before the initiation of chemotherapy (D0), on day 16 of the first cycle of chemotherapy (D16), and on D30. RESULTS The serum HA concentration on D0 in patients with AML, B-ALL, and MCL was higher than in the control group. For all types of hematological malignancy, on D0, serum HA values of nonsurvivors were higher than in survivors. Moreover, patients in relapse had higher levels of serum HA than patients in remission. A strong positive correlation between serum HA and ferritin, β2-microglobulin, and lactate dehydrogenase was found. CONCLUSION Serum HA may serve as a possible prognostic marker for AML, B-ALL, and MCL patients, especially on D0. Prospective case-control studies on larger populations may provide further information.

Iron overload correlates with serum liver fibrotic markers and liver dysfunction: Potential new methods to predict iron overload-related liver fibrosis in thalassemia patients. United European Gastroenterol J 2016; 5:94-103. [PMID: 28405327 DOI: 10.1177/2050640616646525] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2015] [Accepted: 04/03/2016] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Early detection of liver fibrosis in thalassemia patients and rapid initiation of treatment to interfere with its progression are extremely important. OBJECTIVE This study aimed to find a sensitive, easy-to-detect and noninvasive method other than liver biopsy for early detection of liver fibrosis in thalassemia patients. METHODS A total of 244 Chinese Thalassemia patients with non-transfusion-dependent thalassemia (NTDT, n = 105) or thalassemia major (TM, n = 139) and 120 healthy individuals were recruited into the present study, and blood collagen type IV (C IV), precollagen type III (PIIINPC) and hyaluronic acid (HA), aspartate aminotransferase (AST), alanine aminotransferase (ALT) and ferritin were measured. Liver iron concentration was determined by MRI. The correlation of serum markers with liver iron load and liver function was evaluated. RESULTS Serum C IV, PIIINPC and HA were significantly elevated in Chinese patients with NTDT and further elevated in TM patients. Moreover, C IV, PIIINPC and HA were also positively correlated to serum ferritin and liver iron concentration and further elevated during the progression to multi-organ damage in NTDT patients. Finally, serum ferritin and liver iron concentration were significantly correlated with liver dysfunction determined by AST and ALT. CONCLUSION Taken together, our results indicate that monitoring serum C IV, PIIINPC and HA is a potentially sensitive method to predict the risks for iron overload-related liver fibrosis in Chinese thalassemia patients.

Abstract
BACKGROUND Hyaluronic acid (HA) has been found to be an important trigger of atherosclerosis. In this study, we investigate the possible association of serum HA with cardiovascular disease risk in a population of low/intermediate risk for cardiovascular events. METHODS We enrolled 200 subjects with low/intermediate risk for developing cardiovascular disease. High specific C-reactive protein (hsCRP) was used as an indicator of preclinical atherosclerosis. The Framingham score was used to calculate the cardiovascular risk. RESULTS Participants with dyslipidemia had significantly higher levels of serum HA than those without dyslipidemia (t-test, P = 0.05), higher levels of hsCRP (Kruskal-Wallis test, P = 0.04), and higher cardiovascular risk according to the Framingham score (Kruskal-Wallis test, P = 0.05). Serum HA concentration correlated significantly with the Framingham score for risk for coronary heart disease over the next 10 years (Spearman r = 0.152, P = 0.02). Diabetic volunteers had significantly higher HA than those without diabetes (t-test, P = 0.02). Participants with metabolic syndrome had higher serum HA levels and higher hsCRP (Kruskal-Wallis test, P = 0.01) compared to volunteers without metabolic syndrome (t-test, P = 0.03). CONCLUSIONS Serum HA should be explored as an early marker of atheromatosis and cardiovascular risk.

Abstract
Iron chelation therapy is an effective approach to the treatment of iron overload conditions, in which iron builds up to toxic levels in the body and may cause organ damage. Treatments using deferoxamine, deferasirox and deferiprone have been introduced and despite their disadvantages, they remain the first-line therapeutics in iron chelation therapy. Our study aimed to compare the effectiveness of the iron chelation agent TLc-A, a nano chelator synthetized based on the novel nanochelating technology, with deferoxamine. We found that TLc-A reduced iron overload in Caco2 cell line more efficiently than deferoxamine. In rats with iron overload, very low concentrations of TLc-A lowered serum iron level after only three injections of the nanochelator, while deferoxamine was unable to reduce iron level after the same number of injections. Compared with deferoxamine, TLc-A significantly increased urinary iron excretion and reduced hepatic iron content. The toxicity study showed that the intraperitoneal median lethal dose for TLc-A was at least two times higher than that for deferoxamine. In conclusion, our in vitro and in vivo studies indicate that the novel nano chelator compound, TLc-A, offers superior performance in iron reduction than the commercially available and widely used deferoxamine.

Abstract
UNLABELLED Chronic liver diseases may cause inflammation and progressive scarring, over time leading to irreversible hepatic damage (cirrhosis). As a result, the need to assess and closely monitor individuals for risk factors of components of matrix deposition and degradation, as well as the severity of the fibrosis using biomarkers, has been increasingly recognized. AIM Our aim is to review the use of biomarker for diagnosing and defining the severity of liver fibrosis. METHODS A systematic literature review was done using the terms "hyaluronic acid" and "liver fibrosis" as well as the name of each biomarker or algorithm known to be employed. PubMed and Google Scholar were searched, and English language articles indexed between January 2010 and October 2014 in which HA was used as a marker of liver fibrosis were retrieved, regardless of the underlying liver disease. Each author read the publications separately and the results were analyzed and discussed. RESULTS Biomarkers offer a potential prognostic or diagnostic indicator for disease manifestation, progression, or both. Serum biomarkers, including HA, have been used for many years. Emerging biomarkers such as metalloproteinases have been proposed as tools that provide valuable complementary information to that obtained from traditional biomarkers. Moreover, markers of extracellular matrix degradation provide powerful predictions of risk. In order for biomarkers to be clinically useful in accurately diagnosing and treating disorders, age-specific reference intervals that account for differences in gender and ethnic origin are a necessity. CONCLUSIONS This review attempts to provide a comprehensive analysis of the emerging risk biomarkers of liver fibrosis and to describe the clinical significance and analytical considerations of each biomarker pointing out sentinel features of disease progression.

Abstract
Liver complications in haemoglobinopathies (thalassaemia and sickle cell disease) are due to several factors, dominated (beside chronic viral infections, not considered here) by chronic iron overload, biliary obstruction and venous thrombosis. Whereas the latter two factors can cause acute hepatic syndromes, all three mechanisms - when becoming chronic- can produce fibrosis and cirrhosis and even, in thalassaemia, hepatocellular carcinoma. These chronic hepatic complications are an indirect consequence of the significant improvement in life expectancy due to the overall amelioration of disease management. The diagnostic approach has benefited from non invasive (biochemical and imaging) approaches which have considerably reduced the indication of liver biopsy. The therapeutic management involves relatively efficient curative medical, endoscopic or surgical methods, but should rest primarily on preventive measures focused on the haematological causative factors but also on hepatic co-morbidities. This chapter will focus on hepatic complications in thalassaemia and sickle cell disease (SCD), without considering the complications related to virus B or C infections which will be described in another chapter.

Abstract
BACKGROUND Iron overload and hepatitis-C virus (HCV) infection, have been implicated in the evolution of liver disease, in patients with transfusion-dependent beta-thalassaemia major (BTM). However, the impact of these factors in late stages of liver disease in adults with BTM, has not been extensively studied. AIMS To investigate serum indices of iron overload, HCV infection and liver disease, in a cohort of 211 adult Greek patients with BTM, in relation with the findings from liver biopsies. METHODS In this cross-sectional study, 211 patients with BTM were enrolled and studied, in relation with HCV infection, ferritin, transaminases, chelation treatment and antiviral treatment. Based on 109 patients biopsied, we correlated liver fibrosis, haemosiderosis and inflammation, with serum indices and HCV status RESULTS Among all patients, 74.4% were anti-HCV positive (HCV+). Ferritin was positively correlated with transaminases and negatively correlated with age, while it was not significantly different among HCV+ and HCV- patients. Among the HCV+ patients, 55.4% reported antiviral treatment, while genotype 1 predominated. In a subfraction of 109 patients, in which liver biopsy was performed, 89% were HCV+ and 11% HCV-. Fibrosis was significantly correlated with age (P = 0.046), AST (P = 0.004), ALT (P = 0.044) and inflammation (P < 0.001). Advanced fibrosis was present with even minimal haemosiderosis, independently of ferritin values or HCV history. CONCLUSIONS These data suggest that in the late stages of liver disease in BTM patients, iron overload may be the critical determinant, since fibrosis is related to the minimal haemosiderosis, independently of HCV history.

Abstract
Patients with β-thalassemia major require long-term blood transfusions, resulting in hepatic iron overload. Thirty-five Chinese children with β-thalassemia major were recruited in the present studies. Hepatic iron overload was evaluated by histological grading. The relationships between hepatic iron overload and both serum biochemical markers and magnetic resonance imaging (MRI) examination were studied. The majority of the patients showed high degrees of hepatic iron overload by histological study. The degree of hepatic iron overload was correlated with serum ferritin (r = .70, P < .01), hyaluronic acid (r = .58, P = .011), and type III precollagen (r = .55, P = .035). Moreover, hepatic iron overload showed a negative correlation with liver to muscle signal intensity ratio (r = -.44, P = .012), and a positive correlation with red marrow area percentage (r = .52, P < .01). These results indicated that hepatic iron overload might be assessed by serum biochemical markers and MRI examination.
