Abstract
Object Studies have shown a link between homocysteine (Hcy) and heart diseases, kidney diseases, cerebrovascular diseases, liver diseases, and other pathological conditions. However, the relationship between Hcy and liver fibrosis (LF) is unclear. Here, we studied the link between plasma Hcy concentration and LF. Methods We determined and recorded the plasma Hcy concentration, general biochemical parameters, and liver stiffness measurement (LSM) in 1582 subjects, followed by statistical data analyses. Results During different stages of LF, we found a considerable difference (p <0.001 unless specified) in body mass index (BMI), sex, age, Hcy, the levels of alanine transaminase (ALT), gamma-glutamyl transpeptidase (GGT; P = 0.012), triglycerides (TG; P = 0.006), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FBS), and platelet count (PLT). There was a strong association between the plasma Hcy concentration and the serum biomarkers of LF (P <0.001) and the values of LSM (P <0.001). Conclusion The plasma Hcy concentration was substantially different among different stages of LF. The higher the plasma Hcy concentration, the more evident was the degree of LF.

Ann Hepatol 2020; 18:633-639. [PMID: 31078441 DOI: 10.1016/j.aohep.2018.12.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Revised: 12/06/2018] [Accepted: 11/23/2018] [Indexed: 02/04/2023]
Abstract
INTRODUCTION AND OBJECTIVES Liver cirrhosis is characterized by increased intrahepatic resistance, splanchnic vasodilation/angiogenesis, and formation of portosystemic collateral vessels. Collaterals can cause lethal complications such as gastroesophageal variceal hemorrhage. Homocysteine is linked to vascular dysfunction and angiogenesis and higher levels have been reported in cirrhotic patients. It is also known that folic acid supplementation reverses the effects of homocysteine. However, the treatment effect in cirrhosis has yet to be investigated. MATERIAL AND METHODS Liver cirrhosis was induced in Sprague-Dawley rats with common bile duct ligation (CBDL). The CBDL rats randomly received (1) vehicle; (2) dl-homocysteine thiolactone (1g/kg/day); (3) dl-homocysteine thiolactone plus folic acid (100mg/kg/day); or (4) folic acid. On the 29th day, hemodynamic parameters, liver and renal biochemistry, protein expressions of proangiogenic factors, mesenteric vascular density and portosystemic shunting were evaluated. RESULTS In the cirrhotic rats, homocysteine increased mesenteric vascular density and the severity of shunting. It also up-regulated the protein expressions of mesenteric vascular endothelial growth factor (VEGF) and phosphorylated-endothelial nitric oxide synthase (p-eNOS). These effects were reversed by folic acid treatment (P<0.05). CONCLUSION Folic acid ameliorated the adverse effects of homocysteine in the cirrhotic rats, which may be related to down-regulation of the VEGF-NO signaling pathway.

Extrahepatic angiogenesis hinders recovery of portal hypertension and collaterals in rats with cirrhosis resolution. Clin Sci (Lond) 2018; 132:669-683. [PMID: 29449343 DOI: 10.1042/cs20171370] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 02/09/2018] [Accepted: 02/15/2018] [Indexed: 12/20/2022]
Abstract
Liver cirrhosis is characterized by portal hypertension. However, the alteration of portal hypertension-related derangements during cirrhosis resolution is not well known. The present study aimed to establish animal models with cirrhosis resolution and to investigate the relevant changes during this process. Male Sprague-Dawley rats were applied. In reverse thioacetamide (rTAA) model, rats were randomly allocated into four groups with control, thioacetamide (TAA) cirrhosis and rTAA groups that discontinued TAA for 4 or 8 weeks after cirrhosis induction. In reverse bile duct ligation (rBDL) model, rats received choledochoduodenal shunt surgery upon the establishment of cirrhosis and 4, 8, or 16 weeks were allowed after the surgery. At the end, portal hypertension-related parameters were evaluated. Cirrhosis resolution was observed in rTAA groups. Portal pressure (PP) decreased after cirrhosis resolution but remained higher than control group (control, TAA, rTAA4, rTAA8 (mmHg): 5.4 ± 0.3, 12.9 ± 0.3, 8.6 ± 0.4, 7.6 ± 0.6). Further survey found the increased splanchnic blood flow did not reduce during cirrhosis resolution. The extrahepatic pathological angiogenesis was not ameliorated (% of mesenteric window area: 1.2 ± 0.3, 7.3 ± 1.1, 8.3 ± 1.0, 11.3 ± 2.7). In collateral system, the shunting degree reduced while the vessels structure remained. The vascular contractility of all systems and nitric oxide (NO) production were normalized. In rBDL series, PP decreased in rBDL16 groups but the extrahepatic angiogenesis persisted. In conclusion, cirrhosis resolution attenuates but not completely normalizes portal hypertension because of persistently high splanchnic inflow and angiogenesis. In clinical setting, vascular complications such as varices could persist after cirrhosis resolution and further investigation to define the follow-up and treatment strategies is anticipated.
