Liver enzymes and incident diabetes in China: a prospective analysis of 10 764 participants in the Guangzhou Biobank Cohort Study

AbstractWe aimed to investigate whether elevated liver enzymes in the adult population were associated with mortality due to infection. As a population-based cohort study, data from the National Health Insurance Service Health Screening Cohort were used. Adult individuals (aged ≥ 40 years) who underwent standardized medical examination between 2002 and 2003 were included, and infectious mortality was defined as mortality due to infection between 2004 and 2015. Aspartate transaminase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (γ-GTP), AST/ALT ratio, and dynamic AST/ALT ratio (dAAR) were included in multivariable Cox modeling. A total of 512,746 individuals were included in this study. Infectious mortality occurred in 2444 individuals (0.5%). In the multivariable model, moderate and severe elevation in AST was associated with 1.94-fold [hazard ratio (HR):1.94, 95% confidence interval (CI) 1.71–2.19; P < 0.001] and 3.93-fold (HR: 3.93, 95% CI 3.05–5.07; P < 0.001) higher infectious mortality respectively, compared with the normal AST group. Similar results were observed for moderate and severe elevation in ALT and mild, moderate, and severe elevation in γ-GTP. Additionally, a 1-point increase in the AST/ALT ratio and dAAR was associated with higher infection mortality. Elevated liver enzymes (AST, ALT, AST/ALT ratio, γ-GTP, and dAAR) were associated with increased infectious mortality.

Metabolically Healthy

Abstract Aims/hypothesis People with obesity and a normal metabolic profile are sometimes referred to as having ‘metabolically healthy obesity’ (MHO). However, whether this group of individuals are actually ‘healthy’ is uncertain. This study aims to examine the associations of MHO with a wide range of obesity-related outcomes. Methods This is a population-based prospective cohort study of 381,363 UK Biobank participants with a median follow-up of 11.2 years. MHO was defined as having a BMI ≥ 30 kg/m2 and at least four of the six metabolically healthy criteria. Outcomes included incident diabetes and incident and fatal atherosclerotic CVD (ASCVD), heart failure (HF) and respiratory diseases. Results Compared with people who were not obese at baseline, those with MHO had higher incident HF (HR 1.60; 95% CI 1.45, 1.75) and respiratory disease (HR 1.20; 95% CI 1.16, 1.25) rates, but not higher ASCVD. The associations of MHO were generally weaker for fatal outcomes and only significant for all-cause (HR 1.12; 95% CI 1.04, 1.21) and HF mortality rates (HR 1.44; 95% CI 1.09, 1.89). However, when compared with people who were metabolically healthy without obesity, participants with MHO had higher rates of incident diabetes (HR 4.32; 95% CI 3.83, 4.89), ASCVD (HR 1.18; 95% CI 1.10, 1.27), HF (HR 1.76; 95% CI 1.61, 1.92), respiratory diseases (HR 1.28; 95% CI 1.24, 1.33) and all-cause mortality (HR 1.22; 95% CI 1.14, 1.31). The results with a 5 year landmark analysis were similar. Conclusions/interpretation Weight management should be recommended to all people with obesity, irrespective of their metabolic status, to lower risk of diabetes, ASCVD, HF and respiratory diseases. The term ‘MHO’ should be avoided as it is misleading and different strategies for risk stratification should be explored. Graphical abstract

Maternal And Neonatal Outcomes

Abstract Background: Acute fatty liver of pregnancy (AFLP) and hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome are two uncommon disorders that mimic each other clinically, but are distinct pathophysiologically. This study aimed to compare maternal and neonatal outcomes between AFLP and HELLP syndrome.Methods: This retrospective cohort study was performed at a tertiary referral center in Taiwan between June 2004 and April 2020. We used the Swansea Criteria to diagnose AFLP, and the Tennessee Classification System to diagnose HELLP syndrome. Maternal characteristics, laboratory data, complications, and neonatal outcomes were analyzed.Results: During the study period, 21 women had AFLP and 80 women had HELLP syndrome. There was a higher rate of preeclampsia (95.0% versus 23.8%) in the HELLP syndrome group compared to the AFLP group. However, the AFLP group had more other maternal complications including jaundice (85.7% versus 13.8%), acute kidney injury (61.9% versus 15.0%), disseminated intravascular coagulopathy (66.7% versus 8.8%), and sepsis (47.6% versus 10.0%) compared to the HELLP syndrome group. Nevertheless, higher rates of small for gestational age neonates (57.1% versus 33.3%), neonatal respiratory distress syndrome (39.2% versus 8.3%) and neonatal sepsis (34.2% versus 12.5%) were noted in the HELLP syndrome group.Conclusions: AFLP is associated with a higher rate of multiple organ dysfunction in mothers, whereas HELLP syndrome is associated with a higher rate of neonatal morbidity.

Abstract Background: Although recent evidence suggests that nonalcoholic fatty liver disease (NAFLD) is associated with insulin resistance and an increased risk of diabetes, the association between lean NAFLD and incident diabetes is unclear. This study aimed to investigate whether lean NAFLD and overweight/obese NAFLD have similar or dissimilar effects on the risk of new-onset diabetes.Methods: A longitudinal study was performed in 14,482 euglycemic adults who participated in a health check-up program. Fatty liver was diagnosed by abdominal ultrasonography. The outcome of interest was incident diabetes.Cox proportional hazards regression models were applied to calculate HRs with 95% CIs for future diabetes risk.Results: During the median 6.0 years of follow-up, 356 cases of diabetes occurred. Despite a low probability of hepatic fibrosis indicated by the BAAT score, lean NAFLD was positively associated with an increased risk of diabetes. Moreover, after adjusting for sociodemographic and potential confounders, the fullyadjusted HRs (95% CIs) for incident diabetes between lean NAFLD and overweight/obese NAFLD to the reference (lean without NAFLD) were 2.58 (95% CI 1.68 to 3.97) and 2.52 (95% CI 1.79 to 3.55), respectively. In post hoc analysis, the HR (95% CI) for diabetes comparing lean NAFLD to obese/overweight NAFLD was 1.02 (95% CI 0.68 to 1.54, p = 0.909). The results were robust to challenges in multiple subgroup analyses and appeared to be more pronounced for female participants (p for interaction = 0.005).Conclusions: In this cohort study, lean patients with NAFLD had a risk of incident type 2 diabetes similar to that of overweight/obese ones with NAFLD. These findings suggest that lean NAFLD is not a benign condition. Further investigations are needed to gain a better understanding of the pathogenesis and natural history of NAFLD in lean subjects.

Abstract Background Previous studies have revealed that hypertension is one of major risk factors of incident diabetes. However, reliable quantification of the relationship between hypertension and diabetes risk is limited, especially in Chinese people. We aimed to investigate the association between hypertension and risk of incident diabetes in a large cohort of Chinese population. Methods This was a retrospective propensity score-matched cohort study. We enrolled 211809 Chinese adults without diabetes at baseline between 2010 and 2016. The target independent and dependent variable were hypertension at baseline and incident diabetes during follow-up respectively. The one to one propensity score matching using a non-parsimonious multivariable logistic regression was conducted to balance the confounders between 28,946 hypertensive patients and 28,946 non-hypertensive participants. The doubly robust estimation method was used to investigate the association between hypertension and incident diabetes. Result After propensity-score matching, the cumulative incidence of diabetes among hypertensive and non-hypertensive participants were 1627.690 per 100,000 person-years and 1414.422 per 100,000 person-years, respectively. In the propensity-score matching cohort, compared to the non-hypertensive participants, the risk of incident diabetes increased by 14.0% among hypertensive subjects (HR = 1.140, 95% confidence interval (CI): 1.058–1.229, P = 0.00063). After adjusting for the demographic and clinical covariates, diabetes risk increased by 13.1% in the hypertensive group (HR = 1.131, 95%CI: 1.049–1.220, P = 0.00143). And diabetes risk increased by 15.4% among hypertensive subjects after adjusting for the propensity score (HR = 1.154, 95%CI:1.070–1.244, P = 0.00019).In the subgroup analysis, compared to non-hypertensive participants with low propensity score, the risk of incident diabetes increased by 2.6 times among hypertensive patients with high propensity score (HR = 3.610,95%CI: 2.604–5.005,P < 0.00001). In the sensitivity analysis, the risk of diabetes in the hypertensive group increased by 11.7% in the original cohort (HR = 1.117༌95%CI: 1.044–1.196,P = 0.00134) and 19.9% in the weighted cohort(HR = 1.199༌95%CI: 1.149–1.250,P < 0.00001), respectively. Conclusion Hypertension was associated with a 13.1% increase in the risk of developing diabetes in Chinese adults. Additionally, compared to non-hypertensive participants with low propensity score, the risk of incident diabetes increased by 2.6 times among hypertensive patients with high propensity score.
