Association between circulating inflammatory molecules and alcoholic liver disease in men.

The association between alcoholic liver disease (ALD) and the inflammatory response remains controversial. The aim of this study was to explore this association between ALD and inflammation. We enrolled 214 male participants, who were divided into three age-matched groups: ALD (n = 135), chronic alcohol ingestion without ALD (non-ALD; n = 42), and control (n = 37). The BMI was significantly higher in the ALD group than in the non-ALD and control groups (all P = 0.000). Further, the constituent ratio of the liver inflammatory level was significantly higher in the ALD group than in the non-ALD and control groups (P = 0.002 and P = 0.000, respectively). In addition, the median serum ALT, AST, and GGT levels were significantly higher in the ALD group than in the control group (P = 0.023, P = 0.008, and P = 0.000, respectively); these levels were also significantly higher in the ALD group than in the non-ALD group (P = 0.013, P = 0.010, and P = 0.000, respectively). The median serum CRP level was significantly higher in the ALD group than in the non-ALD and control groups (P = 0.006 and P = 0.000, respectively). Further, the median serum TNF-α level was significantly lower in the ALD group than in the non-ALD and control groups (P = 0.004 and P = 0.000, respectively). The median serum sOX40L and HSP70 levels were significantly lower in the ALD group than in the control group (P = 0.008 and P = 0.018, respectively). In addition, the ALT, AST, and GGT levels were positively correlated with the CRP level (r = 0.211, P = 0.002; r = 0.220, P = 0.001 and r = 0.295, P = 0.000, respectively), and the GGT level was negatively correlated with the TNF-α (r = -0.225, P = 0.001), sOX40L (r = -0.165, P = 0.016), and HSP70 levels (r = -0.178, P = 0.009). Further, the Cr level was negatively correlated with the IL-10 level (r = -0.166, P = 0.015). Logistic regression analysis verified that the BMI (OR  =  1.637, 95%CI: 1.374-1.951, P  =  0.000) and GGT level were significantly higher (OR  =  1.039, 95%CI: 1.020-1.059, P  =  0.000) and that the TNF-α (OR  =  0.998, 95%CI: 0.996-1.000, P  =  0.030) and HSP70 levels were significantly lower (OR  =  1.017, 95%CI: 1.003-1.031, P  =  0.029) in the ALD group than in the non-ALD group. Further, the moderate-to-severe ALD patients had a significantly higher serum CRP level (Or =   1.349, 95%CI: 1.066-1.702, P  =  0.013) and significantly lower HSP60 (OR  =  0.965, 95%CI: 0.938-0.993, P  =  0.014) and HSP70 levels (OR  =  0.978, 95%CI: 0.962-0.995, P  =  0.010) than the mild ALD patients. These results suggest that ALD patients may present with obesity, liver damage, and an imbalanced inflammatory immune response, mainly manifesting as decreased levels of immune inflammatory cytokines. In addition, they suggest that certain liver and kidney function parameters and ALD severity are either positively or negatively correlated with certain inflammatory cytokines. Hence, ALD patients may be at increased risks of obesity- and inflammation-related diseases. Accordingly, to control the inflammatory response, preventative measures for patients with this disease should include weight control and protection of liver and kidney function.

PRISMA-Compliant Article: Clinical Characteristics and Factors Influencing Prognosis of Patients With Hepatoid Adenocarcinoma of the Stomach in China.

Most previous studies have been single case reports, and studies with large samples are presently lacking. In addition, no studies have investigated the associations between the clinical characteristics and prognosis of hepatoid adenocarcinoma of the stomach (HAS). The aim of this study was to explore the associations of different clinical characteristics with the ages, serum alpha-fetoprotein (AFP) levels, and survival times of HAS patients. The present study was conducted using the CBM disc, HowNet, Wanfang and VIP data resource systems, and PubMed. According to the PRISMA Flow Diagram, certain case reports from the same center, those that did not provide patient age or sex, and those that did not report serum AFP levels or AFP immunohistochemistry results were excluded. A total of 131 relevant articles, including 124 case reports, 5 reviews, and 2 postgraduate Master's theses, were reported in the above-mentioned five databases. We applied inclusion criteria to case reports on the clinical characteristics and prognosis of HAS, which resulted in the ultimate inclusion of 180 patients from 62 case reports for statistical analyses. The main finding was that the age of the men was significantly higher than that of the women (P = 0.004). In addition, the serum AFP levels of the participants with antral disease were significantly higher than those with nonantral disease (P = 0.001). The median serum AFP levels and survival times significantly differed among the patients with the three lesion types (P = 0.001 and 0.019, respectively). The serum AFP levels of the participants with ulcerative-upheaval-type tumors and purely ulcerative tumors were significantly higher than those with upheaval-type tumors (P = 0.000 and 0.017, respectively). In addition, the serum AFP levels of the participants with ulcerative-upheaval-type tumors were significantly higher than those with ulcerative-type tumors (P = 0.019), and their survival time was also significantly higher (P = 0.000). The serum AFP levels of the participants without metastasis or liver metastasis were significantly lower than those with metastasis or liver metastasis (P = 0.000 and 0.000, respectively), and their survival time was significantly longer (P = 0.000 and 0.001, respectively). Finally, the survival time of the participants treated with surgery was significantly longer than those treated using nonsurgical methods (P = 0.046). However, survival analysis revealed that the survival time was only significantly associated with the presence of metastasis (P = 0.002) and liver metastasis (P = 0.036). The main limitations of this study are as follows: it was a retrospective analysis of published case reports, the clinical data were incomplete, and the cases included in subgroup analyses were different. Our study results have demonstrated that the prognosis of HAS patients is poor. In addition, the survival time is significantly negatively correlated with the presence of metastasis and liver metastasis.

Causes of Thickening of Carotid Intima-Media Thickness in Patients With Alcoholic Liver Disease: A Prospective Observational Study.

Several studies have reported the relationship between alcoholic liver disease (ALD) and carotid intima-media thickness (CIMT). Few studies, however, have investigated the causes of CIMT thickening in patients with ALD. The authors explored the causes of CIMT thickening in patients with ALD. The authors enrolled 152 patients who were stratified into groups: nonthickening CIMT with ALD (group A); thickening CIMT with ALD (group B); nonthickening CIMT without ALD (group C); and thickening CIMT without ALD (group D). The CIMT was significantly different between patients with and without ALD (χ 2= 3.875, P = 0.049). The patients in groups A, B, and C were significantly younger than group D (P = 0.001, 0.036, and 0.001, respectively). The body mass indexes (BMI) in groups A and B were significantly higher than in group C (P = 0.000 and 0.007, respectively). The blood glucose levels in groups B and D were significantly higher than in group C (P = 0.016 and 0.018, respectively). The blood uric acid levels in group B were significantly higher than in groups A, C, and D (P = 0.009, 0.000, and 0.003, respectively). The blood uric acid in group A was significantly higher than in group C (P = 0.002). The serum total cholesterol (TC) levels of patients in group B were significantly higher than in groups A and C (P = 0.027 and 0.000, respectively) and the serum TC level in group A was significantly higher than in group C (P = 0.048). The serum triglyceride (TG) levels in groups A and B were significantly higher than in group C (P = 0.027 and 0.000, respectively). The serum of very low-density lipoprotein (VLDL) levels in group B were significantly higher than in group C (P = 0.000). Although a comparison of the low-density lipoprotein (LDL) and high-density lipoprotein (HDL) serum levels among the 4 groups indicated no changes. The serum LDL levels in group B were significantly higher than in group A (P = 0.008). No significant differences were observed among the groups with respect to serum homocysteine, C-reactive protein (CRP), interleukin-6 (IL-6), malondialdehyde (MDA), superoxide dismutase (SOD), soluble OX40 ligand (sOX40L), or heat shock protein (HSP) 60 or 70. Alcoholic liver disease may result in CIMT thickening. Carotid intima-media thickness is associated with age and metabolic factors in patients with ALD. In addition, ALD might promote the premature occurrence of CIMT thickening. The thickening of carotid artery intima thickness, however, is not associated with cytokine profiles, oxidative balance, or immune responses in patients with ALD.

Changes in tumor necrosis factor-α, heat shock protein 70, malondialdehyde, and superoxide dismutase in patients with different severities of alcoholic fatty liver disease: a prospective observational study.

The relationships among inflammation, oxidative balance, and the severity of alcoholic fatty liver disease (AFLD) remain unknown. The aim of this study is to explore the relationships among tumor necrosis factor alpha (TNF-α), heat shock protein 70 (HSP70), malondialdehyde (MDA), superoxide dismutase (SOD), and the severity of AFLD.From January 2012 to December 2013, 162 participants were enrolled in this study and divided into 4 groups: 44 cases of mild AFLD (group A), 55 cases of moderate-to-severe AFLD (group B), 44 cases of alcohol consumption without AFLD (group C), and 20 cases of no alcohol consumption without AFLD (group D). A cross-sectional study was conducted by detecting the serum levels of TNF-α, HSP70, MDA, and SOD by enzyme-linked immunosorbent assay.The median serum levels of TNF-α and HSP70 among the 4 groups were statistically significant (P = 0.000 and 0.001, respectively). The median serum levels of TNF-α in groups A and B were significantly lower than in group C (P = 0.002 and 0.000, respectively), and the median serum level of TNF-α in group B was significantly lower than in group D (P = 0.023). In addition, the median serum level of HSP70 in group B was significantly lower than in groups A and C (P = 0.002 and 0.000, respectively), and the median serum level of HSP70 in group C was significantly higher than in group D (P = 0.044). However, the median serum level of MDA in group B was significantly lower than only group C (P = 0.008).Chronic alcohol ingestion without AFLD may result in a significant increase in the circulation of certain inflammatory markers; the severity of AFLD is associated with circulating inflammatory markers, and moderate-to-severe AFLD may result in a more significant reduction of these markers. However, moderate-to-severe AFLD may also result in a significant downregulation of oxidative stress products.
