Background Identifying biomarkers for early detection of hepatocellular carcinoma (HCC) remains quite challenging. In this study we aimed to estimate the number of TIE2-expressing monocytes (TEMs) cells, which display pro-tumoral activities and are defined as CD14+, TIE2+, and angiopoietin-2; and its potential use as a possible diagnostic marker in HCC patients complicating HCV induced cirrhosis. Methods Current study was conducted on 112 patients. They were divided into two groups: Group I (78 patients) with HCC complicating HCV induced cirrhosis; and group II chronic hepatitis C patients (34 patients). Both groups were compared to (age and sex-matched) healthy persons as group III (38 persons). Result The number of the circulating TEMs: CD14+ and TIE2+ monocytes were significantly higher in the peripheral blood of HCC patients than HCV LC patients and healthy controls, sensitivity and specificity for HCC diagnosis were respectively: CD14 (89.7%, 83.3%), TIE 2 (76.9%, 83.3%), and Ang-2 (76.9%, 66.7%). Moreover, analysis of the P-value and the odd’s ratio showed that CD14 has the highest predictive value for HCC. Conclusion Our results suggest that TEMs and Ang-2can be used as diagnostic markers for HCC, especially among the high-risk group of patients.

A 66 year old Chinese male with a medical history of hypertension, diabetes mellitus and hepatitis B carrier was diagnosed with hepatocellular carcinoma in 2009. He underwent treatment with selective internal radiation spheres and sorafenib, and multiple cycles of chemotherapeutic agents such as bevacizumab, erlotinib, OXAFI ( intravenous oxaliplatin and doxorubicin given on days 1, 8 and 15 in a 28-day cycle, a daily continuous infusion of fluorouracil and subcutaneous interferon alfa-2b 5 million units administered thrice weekly), thalidomide, capecitabine, and rapamycin over the course of four years. Along the course of treatment, he developed pulmonary embolism and was initially started on anti-coagulation. Two months later, he developed hemoptysis and the anti-coagulants were stopped. During his routine ophthalmology visit for diabetic eye evaluation, he complained of blurring of vision of his left eye for the past four to five weeks. He was found to have central retinal vein occlusion (CRVO) of the left eye, associated with macular edema. Visual acuity was 6/15 for the right eye and 6/60 for the left eye. Eyelids, conjunctiva, cornea, anterior chamber, pupils, lens and ocular motility were normal. Humphrey visual field testing showed a superior arcuate and basal defect. This is the first reported case of CRVO in hepatocellular carcinoma. The etiology of CRVO is multifactorial, withhepatic malignancy, previous major surgery, multiple cycles of chemotherapy and cessation of anticoagulant therapyas possible aetiological factors. His background medical problems of diabetes and hypertension are further contributors.

Mammalian Rbm45 is predominately expressed in neuronal tissue and is integral in brain development and neuronal differentiation under physiological conditions. Dysregulation of Rbm45 has been strongly associated with neurodegenerative disorders in humans and can drive hepatocellular carcinoma through reprogramming lipid metabolism. Intriguingly, Rbm45 is an ancient protein, evolutionarily conserved throughout metazoans, including in sponges which lack a nervous system. Curiously, the evolution of Rbm45 gene structure and protein domain conservation across kingdom Animalia is largely unknown. We performed phylogenetic analysis of Rbm45 nucleotide and amino acid sequences from 36 species representing 9 phyla: Porifera, Cnidaria, Priapulida, Mollusca, Brachiopoda, Arthropoda, Echinodermata, Hemichordata, and Chordata. While the tree from Rbm45 nucleotide sequence data resulted in clades Protostomia and Deuterostomia showing paraphyly, the phylogeny derived from Rbm45 amino acid sequence largely recapitulated known monophyletic relationships among metazoans. Human RBM45 protein structure includes three RNA-binding domains (RBD), a homo-oligomerization association (HOA) domain, a nuclear localization sequence (NLS), and a nuclear export sequence (NES). Multiple sequence alignment across the same 36 taxa used for phylogenetic analysis revealed conservation of all three RBDs, the HOA, and NLS; in contrast the NES was only detected in clade Craniata and not in clades Ambulacraria and Protostomia. Rbm45 gene structure analysis revealed increasing gene complexity concomitant with increasing evolutionary complexity. Rbm45 from non-bilaterian taxa had from 2 to 4 large exons, while bilaterian taxa had between 6 to17 small exons. These findings demonstrate that Rbm45 is an ancient, highly conserved gene among metazoans suggesting a function in a breadth of neural/sensory systems.

Background Liver disease has caused significant morbidity and mortality worldwide. Its epidemiologic and clinical pattern, however, is not well characterized in sub-Saharan countries. Objective This study aimed to describe demographic, clinical characteristics, and patterns of liver disease in a community hospital in Addis Ababa, Ethiopia. Method A retrospective hospital-based study was conducted on patients with liver disease admitted at Ras Desta Damtew memorial hospital, in Addis Ababa-Ethiopia, from February 2015 to April 2020. Result Of the total 212 patients majority, 78.8% were male, 49.1% of patients were in the age range of 31-50 with a median age of 42. The most common initial clinical presentation was ascites (87.7 %), and more than half of patients (56.6%) had a history of alcohol misuse documented on their medical charts. Chronic liver disease (cirrhosis) was found in 177 (83.5%), and Hepatocellular Cancer accounted for 7.5% of the patients. Alcohol misuse caused 45% of chronic Liver Disease, followed by Hepatitis B virus infection. Conclusion Chronic liver disease is the most common form of liver disease, and the most affected were middle-aged men. The common cause of chronic liver disease was alcohol followed by hepatitis B virus infection.

Introduction: Aflatoxins are cytotoxic andserve as one of the key risk factors of hepatocellular carcinoma. Currently, plants and extract are widely used as potential scavenging substances for the detoxification of mycotoxins. Thus, this study aims to investigate the activity of the crude ethanolic leaves extract from Alchorneacordifolia in aflatoxicosis prevention. Material and Methods: The phytochemical screening was performed through qualitative analysis based on coloring and/or precipitation reactions. Groups of rats were treated daily with a mixture dose of aflatoxin B1 (AFB1) at 150 µg/kg and the crude extract of Alchorneacordifolia at doses of 50, 100, and 300 mg/kg for 21 days. The body weight, biochemical, and histological assessments were determined. Results: The phytochemical screening revealed the presence of polyphenols, flavonoids, sterols and terpenoids, quinoid compounds, tannins catechic and alkaloids. AFB1 treatmentcaused a significant increase of transaminases, urea, and creatinine abundances but reduced the rates of albumin and total proteins. Alchorneacordifolia administration alleviated biochemical parameters and body weight gain compared with the AFB1 group (p<0.05). The histological lesions of organs (liver and kidney) caused by AFB1 were significantly improved after administration of the extract at a dose of 300 mg/kg. Conclusion: This plant plays a beneficial role in AFB1-induced injury and may be used in the treatment of aflatoxicosis.
