Abstract
Introduction Thyroid cancer incidence is increasing, and adiposity-related conditions are gaining space in its pathogenesis. In this study, we aimed to detect any anthropometric, biohumoral, and clinical features that might be associated with thyroid nodule malignancy, potentially representing novel non-invasive markers of thyroid cancer. Materials and methods The study was conducted in a group of 142 consecutive outpatients (47 men and 95 women) who underwent fine-needle aspiration biopsy/cytology (FNAB/C) due to suspicion of malignancy from January 2018 to September 2022. We compared lipid and glycemic blood profiles as well as non-invasive liver fibrosis indexes such as aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (AAR), AST to platelet ratio index (APRI), and fibrosis index based on four factors (FIB-4) between patients with benign and malignant newly diagnosed nodules. Then, we performed receiver operating characteristic (ROC) analysis to assess their best cutoff values for discrimination of malignant nodules and chi-squared test to evaluate the association of specific dysmetabolic conditions with malignancy. To understand whether and to what degree dysmetabolic conditions increased the risk of thyroid nodule malignancy, we also calculated the odds ratio (OR) of the main biomarkers. Results After FNAB/C, 121 (85%) patients were diagnosed with benign thyroid nodules, while 21 (15%) individuals were diagnosed with thyroid cancer. Comparing patients with benign and malignant nodules, we found that individuals with thyroid cancer exhibited increased body mass index (BMI) (p = 0.048) and fasting plasma glucose (p = 0.046). Intriguingly, considering non-invasive scores for liver fibrosis, subjects with thyroid cancer presented increased AAR (p < 0.001) and APRI (p = 0.007), and these scores were associated with malignancy (p < 0.005) with OR = 7.1 and OR = 5, respectively. Moreover, we showed that only in the cancer group, low levels of vitamin D correlated with stigmata of impaired metabolism. Discussion In our study, AAR and APRI scores were associated with thyroid nodule malignancy and could be used to predict it and to speed up the diagnostic process. From a pathogenic point of view, we speculated that metabolic-associated fatty liver disease (MAFLD) along with hyperglycemia and vitamin D deficiency may represent putative drivers of thyroid carcinogenesis.

Abstract
Impaired fasting glucose (IFG) is a reversible intermediate hyperglycemia stage with an increasing risk of diabetes and related complications. Our study was designed to identify the relationship between the serum anion gap and the risk of progressing to impaired fasting glucose and diabetes. Here, we performed a prospective, population-based study among 1191 Chinese individuals aged 22-87 years who took health examinations annually between 2006 and 2012 including clinical features and plasma metabolites. All of the participants had no history of diabetes or related chronic complications. Logistic regression analysis was designed to examine the associations between clinical and metabolomic factors and the risk of developing IFG or diabetes. Among them, 58 subjects whose fasting glucose were between 6.1 and 7 mmol/L were diagnosed as IFG or diabetes. After adjusting for age, sex, body mass index (BMI), high-density lipoprotein (HDL), low-density lipoprotein (LDL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), systolic blood pressure (SBP), diastolic blood pressure (DBP), potassium, and albumin at baseline, the participants in the upper tertiles of serum anion gap (SAG) had higher odds of progressing to IFG or diabetes than those in the lower tertiles. A receiver operating characteristic (ROC) curve was analyzed, and the optimal cutoff level for the anion gap to predict incident IFG or diabetes was 13.76 mmol/L, and the area under the ROC curve (AUC) was 0.623. Our data demonstrate that a higher serum anion gap is associated with the risk of developing IFG or diabetes.

Ochiai H, Shirasawa T, Yoshimoto T, Nagahama S, Watanabe A, Sakamoto K, Kokaze A. Elevated alanine aminotransferase and low aspartate aminotransferase/alanine aminotransferase ratio are associated with chronic kidney disease among middle-aged women: a cross-sectional study. BMC Nephrol 2020; 21:471. [PMID: 33172399 PMCID: PMC7653768 DOI: 10.1186/s12882-020-02144-6] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2020] [Accepted: 10/30/2020] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) to ALT ratio (AST/ALT ratio) have been shown to be related to non-alcoholic fatty liver disease or insulin resistance, which was associated with chronic kidney disease (CKD). However, it is unclear whether ALT and AST/ALT ratio are associated with CKD. In this study, we examined the relationship of ALT and AST/ALT ratio to CKD among middle-aged females in Japan. METHODS The present study included 29,133 women aged 40 to 64 years who had an annual health checkup in Japan during April 2013 to March 2014. Venous blood samples were collected to measure ALT, AST, gamma-glutamyltransferase (GGT), and creatinine levels. In accordance with previous studies, ALT > 40 U/L and GGT > 50 U/L were determined as elevated, AST/ALT ratio < 1 was regarded as low, and CKD was defined as estimated glomerular filtration rate < 60 mL/min/1.73 m2 and/or proteinuria. Logistic regression model was used to calculate the odds ratio (OR) and 95% confidence interval (CI) for CKD. RESULTS "Elevated ALT and elevated GGT" and "elevated ALT and non-elevated GGT" significantly increased the OR for CKD when compared with "non-elevated ALT and non-elevated GGT" (OR: 2.56, 95% CI: 2.10-3.12 and OR: 2.24, 95% CI: 1.81-2.77). Compared with "AST/ALT ratio ≥ 1 and non-elevated GGT", "AST/ALT ratio < 1 and elevated GGT" and "AST/ALT ratio < 1 and non-elevated GGT" significantly increased the OR for CKD (OR: 2.73, 95% CI: 2.36-3.15 and OR: 1.68, 95% CI: 1.52-1.87). These findings still remained after adjustment for confounders. CONCLUSIONS Elevated ALT was associated with CKD regardless of GGT elevation. Moreover, low AST/ALT ratio was also associated with CKD independent of GGT elevation.

Abstract
Background: The associations of coffee consumption with the circulating level of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) remains controversial. We conducted a meta-analysis of observational studies to sum up the existing evidence about this matter.Methods: A comprehensive literature-search up to January 2020, using PubMed, Embase and Web of Science databases, was conducted to identify the relevant observational studies that examined the associations of coffee consumption with the circulating level of ALT and AST. The standard mean difference (SMD) for the level of ALT and AST, odds ratio (OR) for the elevated ALT and AST and their corresponding 95% CIs for the highest versus lowest categories of coffee intake were determined.Results: A total of 19 observational studies, which involved 222,067 individuals, were included in this meta-analysis. The combined SMD suggested that coffee consumption was associated with a lower level of ALT (SMD = -0.14, 95% CI: -0.22 to -0.06; p = 0.001) and AST (SMD = -0.17, 95% CI: -0.20 to -0.13; p < 0.001), respectively. Meanwhile, the overall multivariable adjusted OR showed that coffee consumption was inversely associated with the elevated ALT (OR = 0.69, 95% CI: 0.60 to 0.79; p < 0.001) and AST (OR = 0.62, 95% CI: 0.48 to 0.81; p < 0.001), respectively.Conclusion: The results of this meta-analysis suggest that coffee consumption is inversely associated with the circulating level of ALT and AST, and elevated ALT and AST. More randomized controlled trials are needed to elaborate the concerned issues.

Abstract
Objectives To identify the association of type 2 diabetes (T2DM) and liver disease with elevated ALT and factors associated with increased ALT in patients with and without T2DM. Design and setting We performed a retrospective study in adults with ≥ 2 claims for blood tests recorded in the Medical Data Vision claims database between 2010 and 2016. Participants Patients were entered into T2DM and non-DM groups based on diagnosis and medication claim codes. Primary outcome measure The primary endpoint was the first follow-up ALT elevation over three times the normal value, and etiologies were categorized by subsequent diagnoses. We estimated the ALT elevation incidence and association with T2DM using Poisson regression and Cox proportional hazard models. Results We identified 3161 cases of elevated ALT in 104,903 patients (follow-up, 280,659 patient-years). The age- and sex-adjusted incidence of elevated ALT in the T2DM group (13.47 per 1000 patient-years; 95% confidence interval (CI) 12.53-14.48) was significantly higher than that in the non-DM group (8.43 per 1000 patient-years; 95% CI 7.72-9.20, p < 0.0001). Compared to the non-DM group, the T2DM group had an approximately 3.5 times higher risk of fatty liver-related ALT elevation (adjusted hazard ratio (HR), 3.54; 95% CI 1.90-6.58). T2DM was not associated with an increased incidence of jointly elevated ALT and total bilirubin (adjusted HR, 0.94; 95% CI 0.77-1.15). Conclusion T2DM is strongly associated with increased liver enzymes secondary to fatty liver. The causes of liver enzyme abnormalities were not fully characterized due to a high proportion of unexplained ALT elevation.

Abstract
UNLABELLED GIFT-I is a phase 3 trial evaluating the efficacy and safety of a 12-week regimen of coformulated ombitasvir (OBV)/paritaprevir (PTV)/ritonavir (r) for treatment of Japanese hepatitis C virus genotype 1b-infected patients. It consists of a double-blind, placebo-controlled substudy of patients without cirrhosis and an open-label substudy of patients with compensated cirrhosis. Patients without cirrhosis were randomized 2:1 to once-daily OBV/PTV/r (25 mg/150 mg/100 mg; group A) or placebo (group B). Patients with cirrhosis received open-label OBV/PTV/r (group C). The primary efficacy endpoint was the rate of sustained virological response 12 weeks posttreatment in interferon-eligible, treatment-naive patients without cirrhosis and hepatitis C virus RNA ≥100,000 IU/mL in group A. A total of 321 patients without cirrhosis were randomized and dosed with double-blind study drug (106 received double-blind placebo and later received open-label OBV/PTV/r), and 42 patients with cirrhosis were enrolled and dosed with open-label OBV/PTV/r. In the primary efficacy population, the rate of sustained virological response 12 weeks posttreatment was 94.6% (106/112, 95% confidence interval 90.5-98.8). Sustained virological response 12 weeks posttreatment rates were 94.9% (204/215) in group A, 98.1% (104/106) in group B (open-label), and 90.5% (38/42) in group C. Overall, virological failure occurred in 3.0% (11/363) of patients who received OBV/PTV/r. The rate of discontinuation due to adverse events was 0%-2.4% in the three patient groups receiving OBV/PTV/r. The most frequent adverse event in patients in any group was nasopharyngitis. CONCLUSION In this broad hepatitis C virus genotype 1b-infected Japanese patient population with or without cirrhosis, treatment with OBV/PTV/r for 12 weeks was highly effective and demonstrated a favorable safety profile.

Abstract
There is an important set of cirrhotic and diabetic patients that present both diseases. However, information about metabolic and cellular blood markers that are altered, in conjunction or distinctively, in the 3 pathological conditions is scarce. The aim of this project was to evaluate several indicators of prooxidant reactions and the membrane composition of blood samples (serum and red blood cells (RBCs)) from patients clinically classified as diabetic (n = 60), cirrhotic (n = 70), and diabetic with liver cirrhosis (n = 25) as compared to samples from a similar population of healthy individuals (n = 60). The results showed that levels of TBARS, nitrites, cysteine, and conjugated dienes in the RBC of cirrhotic patients were significantly increased. However, the coincidence of diabetes and cirrhosis partially reduced the alterations promoted by the cirrhotic condition. The amount of total phospholipids and cholesterol was greatly enhanced in the patients with both pathologies (between 60 and 200% according to the type of phospholipid) but not in the patients with only one disease. Overall, the data indicate that the cooccurrence of diabetes and cirrhosis elicits a physiopathological equilibrium that is different from the alterations typical of each individual malady.

Abstract
Elevated circulating alanine aminotransferase (ALT) and γ-glutamyltransferase (γ-GTP) activities, and the accumulation of fat, particularly visceral fat, in healthy and preclinical subjects reportedly increase the risk for metabolic diseases such as diabetes. In the present study, we examined the associations between these hepatic enzymes and the total visceral and subcutaneous fat area, and for both regions of fat independently, in healthy and preclinical middle-aged Japanese men. We conducted a cross-sectional study of men who participated in health check-ups in Japan. We removed participants, who were diagnosed with metabolic diseases at the time of the health check-up. Three hundred fifteen subjects aged 40-64 y (mean±SD, 50.5±6.9 y) were selected. We compared associations between the total visceral and subcutaneous fat area, and for both regions independently, with various clinical parameters, including hepatic enzyme markers, using Spearman's rank correlation coefficient analysis and multiple linear regression analysis. The total visceral and subcutaneous fat area and both regions independently were positively associated with body mass index, systolic and diastolic blood pressure, fasting blood glucose, total cholesterol, low-density lipoprotein cholesterol, aspartate aminotransferase, ALT and γ-GTP. ALT and γ-GTP activities were the strongest explanatory variables for increased visceral fat area, independent of the subcutaneous fat area. In contrast, these hepatic enzymes were not explanatory variables for increased subcutaneous fat area. The results of the present study show that the accumulation of visceral fat is positively associated with ALT and γ-GTP activities independently of subcutaneous fat area in healthy and preclinical Japanese men.

Abstract
It has long been proposed that elevation of liver enzymes including alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyltransferase (GGT) may be associated with insulin resistance (IR). In the present study, we aimed to investigate the association of the above mentioned liver enzymes with IR by using hyperinsulinemic euglycemic clamp, as well as their relationship with individual component of metabolic syndrome (MetS) in 95 newly diagnosed type 2 diabetes (T2DM) Chinese patients. All the diagnosed patients did not use drugs for treatment of diabetes or dyslipidemia previously and were divided into IR and non-IR groups. The results showed that IR group had significantly higher ALT, AST, and GGT (P<0.01, P<0.01, and P<0.05, respectively) compared with non-IR group. According to the individual MetS component, ALT and AST were significantly increased in patients with high blood pressure compared with those without (both P<0.001); ALT and GGT were increased in patients with high triglyceride (P<0.05 and P<0.01); AST was increased in patients with central obesity (P<0.05). In correlation analysis, a significant association was found between the three liver enzymes and clamp insulin sensitivity index (all P<0.001). In the linear regression analysis, ALT was the determinant of clamp ISI, independent of age, sex, BMI, and fasting and OGTT 2 h plasma glucose (P<0.0001). In conclusion, liver enzymes, especially ALT, were significantly associated with IR according to direct clamp assessment, which were independent of the traditional risk factors in diabetic patients; and individual liver enzymes may have different relationship with individual component of MetS.

Abstract
To investigate the relation of alcohol use and cigarette smoking to glucose tolerance status, we performed a cross-sectional study of 3038 male officials aged 46-59 years in the Self-Defense Forces. Glucose tolerance status was determined by a 75-g oral glucose tolerance test. A self-administered questionnaire was used to ascertain alcohol use, smoking habits, and other lifestyle characteristics. Statistical adjustment was made for parental history of diabetes, body mass index, and leisure-time physical activity. Alcohol use was positively associated with impaired fasting glucose, impaired glucose tolerance, and type 2 diabetes mellitus each. The association was dose-dependent, with odds of each category of glucose intolerance increased even among those with moderate alcohol use. Cigarette smoking was not related to any categories of glucose intolerance. Alcohol use may confer increased risks not only of type 2 diabetes mellitus but also of preceding glucose intolerance status. Smoking does not seem to deteriorate glucose tolerance.

Abstract
OBJECTIVE To test the hypothesis that enzymes conventionally associated with liver dysfunction (aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase [GGT], and alkaline phosphatase) may predict diabetes. RESEARCH DESIGN AND METHODS From a population-based diabetes survey, we selected 1,441 men and women in whom serum enzyme levels were < or =3 SDs of the mean population value, alcohol intake was <250 g/week, and hepatitis B and C virus testing was negative. At follow-up (7 years), 94 subjects developed diabetes and 93 impaired glucose tolerance (IGT). RESULTS At baseline, all four enzymes were related to most of the features of the metabolic syndrome. After controlling for sex, age, adiposity/fat distribution, alcohol intake, serum lipids, and blood pressure, higher alanine aminotransferase and GGT values were significantly (P < 0.01) associated with both IGT and diabetes, whereas alkaline phosphatase was associated with diabetes only (P = 0.0004) and aspartate aminotransferase with IGT only (P = 0.0001). Raised GGT alone was associated with all the features of the metabolic syndrome. Raised GGT was a significant predictor of either IGT or diabetes (odds ratio 1.62 [95% CI 1.08-2.42] top quartile vs. lower quartiles, P < 0.02) after controlling for sex, age, adiposity/fat distribution, alcohol consumption, fasting plasma insulin and proinsulin levels, and 2-h postglucose plasma glucose concentrations. CONCLUSIONS Although mild elevations in liver enzymes are associated with features of the metabolic syndrome, only raised GGT is an independent predictor of deterioration of glucose tolerance to IGT or diabetes. As GGT signals oxidative stress, the association with diabetes may reflect both hepatic steatosis and enhanced oxidative stress.

Abstract
AIMS/HYPOTHESIS Several studies have reported that coffee has a protective effect against the development of type 2 diabetes. However, few of these studies used the standard glucose tolerance test to diagnose type 2 diabetes. The aim of this study was to investigate the relationship between coffee and green tea consumption and glucose tolerance status as determined using a 75-g OGTT. METHODS We performed a cross-sectional study of 3224 male officials of the self-defence forces. Glucose tolerance status was determined in accordance with the 1998 World Health Organization criteria, and average intakes of coffee and green tea over the previous year were assessed by a self-administered questionnaire. The figures obtained were adjusted for BMI, physical activity and other factors. RESULTS A total of 1130 men were identified as having glucose intolerance (IFG, IGT or type 2 diabetes). Compared with those who did not consume coffee on a daily basis, fasting and 2-h post-load plasma glucose levels were 1.5% and 4.3% lower in those who drank 5 cups of coffee or more per day respectively. The adjusted odds ratios of glucose intolerance for categories of <1, 1-2, 3-4 and >/=5 cups of coffee per day were 1.0 (referent), 0.8 (95% CI 0.6-1.0), 0.7 (95% CI 0.6-0.9) and 0.7 (95% CI 0.5-0.9) respectively (p=0.0001 for trend). No clear association was observed between green tea drinking and glucose tolerance status. CONCLUSIONS/INTERPRETATION Coffee consumption may inhibit postprandial hyperglycaemia and thereby protect against the development of type 2 diabetes mellitus.
