Family hypercholesterolemia (HSX) is a form of genetically deterministic increase in blood lipid levels associated with a high risk of cardiovascular disease, usually at a young age. HSX is a common genetic disease found in the general population in most countries in 1:500 people. Clinically xantomas are found in achilles tendor and wrist flexors, lipoid arc of the cornea, concentration of total cholesterol and low-density lipoproteins is 4.911.6 mmol/l. Gilberts syndrome is a hereditary benign hyperbilirubinium, associated with a decrease in the functional activity of the liver enzyme uridinfosfat-glucuronosil transferase. Clinically, this syndrome appers in intermittent jaundice, which is provoked by physical activity, consumption of alcoholic beverages, insulation and an increase in the level of indirect bilirubin within 20100 micromol/ml. The article presents a rare clinical case of genetic combination of HSC SSC and Gilbert syndrome a young patient has and discusses the elevated bilirubin levels protective role in the atherosclerosis progression in Gilbert syndrome.

Abstract Background: Certain antiepileptic drugs (AEDs) such as valproic acid (VPA) and lamotrigine (LTG) would bring some abnormalities on liver function, ranging from mild malfunction of liver tests to serious hepatotoxicity. The former manifests temporary and reversible elevation of bilirubin and liver enzyme, which is usually dose-dependent and the abnormality can return to normal shortly after the drug was withdrawn. Levetiracetam (LEV), as a newly broad-spectrum AED with relatively fewer side-effects and fewer drug interactions, is increasingly used as adjunctive therapy to treat generalized epilepsy. Gilbert syndrome(GS)is characterized by mild, chronic, intermittent unconjugated hyperbilirubinemia without other hepatic diseases. Fasting, stress, along with some liver toxic drugs would make it clinically apparent. However, when GS co-exists with epilepsy, how to differentiate which one is responsible for the abnormality of bilirubin poses a challenge to us. We herein describes a patient with epilepsy complicated by mildly and intermittently elevated bilirubin, and after various examinations especially for whole-exome sequencing(WES)and liver biopsy, we made a definite diagnosis of GS. Case presentation: A 25-year-old male with epilepsy suffering from intermittently and mildly elevated bilirubin, and relevant imaging information led us consider the diagnosis of idiopathic generalized epilepsy (IGE). After administration of AEDs, the indirect bilirubin remained still slightly elevated even while taking LEV. Then he was referred to the department of gastroenterology in our hospital, the results of diagnostic tests, clinical manifestation, imaging studies, WES and liver biopsy all made contributions to our diagnosis of GS rather than the hepatic injury induced by AEDs. Conclusions: This report presents us with a case of an epilepsy patient complicated by repeatedly elevated bilirubin and finally was diagnosed with GS. By referring to literatures and genetic testing, though, no shared genetic and pathophysiological basis between epilepsy and GS was found, and enzymes responsible for the metabolism of AEDs took no part in the pathogenesis of GS. Our experiences will help clinicians to better differentiate the etiology of repeatedly elevated bilirubin of epilepsy patients during the process of treatment. Key words: Epilepsy, Gilbert syndrome, Valproic acid, Lamotrigine, Levetiracetam, hyperbilirubinemia.

Abstract Background- HDL inhibits atherosclerosis development from radiation damage, nonetheless, the underlying mechanism is yet to be defined.Methods-This study used radiation patients along with cultured mouse aortic endothelial cells (MAECs) to investigate the process. Firstly, 158 patients from the oncology department of Jingzhou hospital who received radiation after neck cancers participated, and their arterial function was monitored by B ultrasound. Similarly, HDL and other blood lipid indexes were also tested. Then, MAECs were isolated and cultured and passed through MTT assay to test the HDL protective role on UVB radiation along with western blotting to test some apoptosis protein expression and possible molecules.Results-Firstly, those patients with high HDL levels were less likely to develop atherosclerosis, with statistical differences. We observed that MAECs treated with UVB were damaged significantly however HDL reversed the cell damage in a dose-depended manner. In the meantime, the apoptosis process was assessed and found that HDL inhibited the apoptosis caused by UVB. Western blotting results showed that HDL enhanced phosphatidylinositol 3-kinase (PI3K) in addition to Akt phosphorylation in MAECs.Conclusion-These results suggest that HDL protected UVB-mediated apoptosis by activation of a mechanism involving PI3K/Akt signaling pathway.

Background: Platelets can influence progression of plaque formation by facilitating recruitment of inflammatory cells at the sites of atherosclerotic lesions. A C-type lectin-like receptor, CLEC-2, abundantly expressed on the platelet surface, has been shown to regulate lymphatic development in utero though an interaction with Podoplanin. Interestingly, lymphatic vasculature is increased in ischemic and inflamed hearts, and in cholesterol-rich atherosclerotic lesions. Moreover, Podoplanin expression is up-regulated on inflammatory macrophages and on T-helper 17 cells. However, the role of the Podoplanin - CLEC-2 interaction in atherosclerosis remains unknown. Aim: We sought to investigate the role of CLEC-2 on atherosclerotic development in ApoE-deficient mice. Methods: CreERT.CLEC-2fl/fl x ApoE-/- and litter-matched ApoE-/- mice were treated with tamoxifen at the age of 9 weeks and were put on a high-fat diet for 6 weeks. Animals were killed at the age of 16 weeks, when platelet function assays and atherosclerosis assays were carried out. Results: Expression of CLEC-2 was abolished in tamoxifen-treated CreERT.CLEC-2fl/fl x ApoE-/- mice (n=8), whereas normal levels were seen in ApoE-/- controls (n=10) also treated with tamoxifen. CreERT.CLEC-2fl/fl x ApoE-/- and ApoE-/- mice had similar baseline characteristics, comparable levels of platelet glycoprotein expression (GPIb, GPIIbIIIa and GPVI) and normal platelet responses to platelet agonists (collagen-related peptide, PAR-4 peptide, ADP and arachidonic acid). Blood lipid levels were comparable between CreERT.CLEC-2fl/fl x ApoE-/- and control animals. Atherosclerotic plaque burden was significantly higher in the aortas of CreERT.CLEC-2fl/fl x ApoE-/- mice fed a high-fat diet for 6 weeks compared with their ApoE-/- counterparts. The higher plaque burden was seen consistently throughout the aorta, but reached significance at the level of whole aorta, abdominal aorta, outer curvature and the left subclavian region. This was seen in both male and female animals. Conclusions: The platelet-borne CLEC-2 receptor appears to have a protective role against atherogenesis in atheroprone mice. Further research to investigate the underlying mechanisms is warranted.

Gilbert syndrome (GS) is characterized by intermittent indirect bilirubin elevation. Several antiepileptic drugs (AEDs) impair the liver function to different degrees, such as valproic acid, lamotrigine, phenobarbital, phenytoin, and carbamazepine. Herein, we present the case of a 26-year-old epileptic patient with frequently recurring mild hyperbilirubinemia during taking AEDs. After repeated adjustment of the doses and types of AEDs, the bilirubin level still remained elevated. He was then referred to the Gastroenterology Department. The results of diagnostic tests, clinical manifestation, imaging studies, liver biopsy and whole-exome sequencing all made contributions to our conclusion that GS played an important role in the elevation of bilirubin. Ultimately, his seizure was controlled by levetiracetam (500 mg per day) and he was advised to periodically undergo the liver function tests.

Gilbert syndrome characterized by jaundice with intermittent elevations of indirect bilirubin, in the absence of haemolysis or underlying liver disease, has both autosomal dominant and recessive inheritance. Crigler-Najjar syndrome type II (CNS2) is a hereditary disorder of bilirubin metabolism characterized by unconjugated hyperbilirubinemia due to reduced and inducible activity of hepatic bilirubin glucuronosyltransferase (GT). We report 20 children between age 5 to 15 years with unconjugated hyperbilirubenemia who were given seven days of oral phenobarbitone (5mg/kg/day) and decrease in level of bilirubin was noted. There was only 30-40% reduction of bilirubin in Crigler Najjar Syndrome Type 2 compared to Gilberts Syndrome in which bilirubin level normalised. This case series highlights the importance of simple test to differentiate these two conditions. This test is also very helpful in a place where enzyme level and mutational study cannot be done.J Nepal Paediatr Soc 2015;35(1):82-84

 Excessive consumption of alcoholic beverages is a serious cause of liver disease worldwide. Any abnormality or dysfunction of the liver leads major impairment of the organ function, which in turn, influences the health of the individual. Alcoholic liver disease (ALD) includes fatty liver, hepatic inflammation, liver cirrhosis, fibrosis, alcoholic hepatitis and finally hepatocellular carcinoma. The metabolism of ethanol generates reactive oxygen species, which play a significant role in the deterioration of alcoholic liver disease. Oxidative stress has been considered as a conjoint pathological mechanism, and it contributes to initiation and progression of liver injury. Antioxidants, phytochemicals, such as polyphenols, regulate the expression of ALDassociated proteins and peptides, namely, catalase, superoxide dismutase, glutathione, glutathione peroxidase, and glutathione reductase. Application of antioxidants signifies a rational curative strategy to prevent and cure liver diseases involving oxidative stress. Although conclusions drawn from clinical studies remain uncertain, animal studies have revealed the promising in-vivo therapeutic effect of antioxidants on liver diseases. Natural antioxidants contained in edible or medicinal plants often possess strong antioxidant and free radical scavenging abilities as well as anti-inflammatory action, which are also supposed to be the basis of other bioactivities and health benefits. Med Phoenix.
