ABSTRACT

Objective To investigate whether there was a correlation between serum liver enzyme levels and blood pressure in the Chinese Han population with nonalcoholic fatty liver disease (NAFLD) in Shandong coastal regions in China. Methods A total of 269 NAFLD patients who lived in Shandong coastal regions and attended or underwent physical examination in Qingdao Municipal Hospital from December 2019 to June 2020 were enrolled, among whom 105 had hypertension and 164 did not have hypertension. Morning blood pressure was measured to calculate mean arterial pressure (MAP), and laboratory tests were performed to measure the serum levels of liver enzymes [alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), and alkaline phosphatase (ALP)] and fasting blood glucose (FBG). The independent samples t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. A Pearson correlation analysis was used to investigate the correlation of four liver enzymes with the indices including MAP, and a binary logistic regression model was used to analyze the impact of serum liver enzymes on hypertension. Results Compared with the non-hypertension group, the hypertension group had significantly higher body mass index (BMI), MAP, and GGT (all P < 0.05). For all NAFLD patients and the NAFLD patients without hypertension, male patients had significantly higher BMI, MAP, ALT, AST, and GGT than female patients (all P < 0.05), and for the NAFLD patients with hypertension, male patients had a significantly higher level of GGT than female patients ( P < 0.05). There was a significant difference in the distribution of GGT between the hypertension group and the non-hypertension group, and compared with the non-hypertension group, the hypertension group had a significantly higher proportion of patients with GGT exceeding the normal range ( χ 2 =4.781, P =0.029). Serum GGT level was correlated with MAP within the normal range (70-105 mm Hg) ( r =0.178, P =0.011), while there was no significant correlation when MAP exceeded the normal range ( P =0.415). After adjustment for age and sex, the binary logistic regression model showed that AST level was positively associated with hypertension in the population with NAFLD (odds ratio [ OR ]=1.011, 95% confidence interval [ CI ]: 1.000-1.022, P =0.040), and after further adjustment for BMI and FBG, the results showed that AST level was still positively associated with hypertension ( OR =1.011, 95% CI : 1.000-1.022, P =0.044). Conclusion In Chinese Han population with NAFLD in Shandong coastal regions, higher levels of AST may predict an increased risk of hypertension.

ABSTRACT

Objective To investigate the clinical value of alpha-fetoprotein (AFP) combined with gamma-glutamyl transpeptidase (GGT)/aspartate aminotransferase (AST) ratio in the diagnosis of hepatitis B virus (HBV)-associated hepatocellular carcinoma (HCC). Methods A total of 352 subjects who received treatment or underwent physical examination in Renmin Hospital of Wuhan University from January 15 to June 15, 2020, were enrolled, among whom there were 86 healthy controls (HC group), 68 patients with chronic hepatitis B (CHB group), 69 patients with liver cirrhosis (LC group), and 129 patients with HCC (HCC group), and a retrospective analysis was performed for the serological test results of all subjects. An analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference t -test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between multiple groups, and the Nemenyi method was used for further comparison between two groups. A binary logistic regression analysis was used to calculate predictor variables; a receiver operating characteristic (ROC) curve was plotted for AFP, GGT/AST, and the predictor variables used alone or in combination, and the area under the ROC curve (AUC), sensitivity, and specificity were calculated; the Z test was used for comparison of AUC. Results The HCC group had significantly higher GGT/AST ratio and AFP than the other groups (all P < 0.05). The ROC curve analysis showed that AFP combined with GGT/AST ratio had a significantly higher AUC than AFP alone in the HCC group vs the LC group, the HCC group vs the HC+CHB+LC groups, and the HCC group vs the CHB+LC groups ( Z =2.684, 2.241, and 2.415, P =0.007, 0.025, and 0.016). Conclusion AFP combined with GGT/AST ratio can improve the clinical diagnostic performance of HBV-related HCC and thus has a certain diagnostic value.

ABSTRACT

Abstract Purpose Coleus forskohlii Briq., a medicinal plant originally from India, has been indicated against heart disease, expiratory disorders, convulsions, and hepatic changes, among others. In view of the broad pharmacological potential of the plant and the scarce information about its effects, the objective of the present study was to investigate the effect of its use for pretreatment of partially hepatectomized rats. Methods The animals were divided into two experimental groups: Control (CG) receiving physiological saline for 10 days before partial hepatetctomy, and Treated (TG) receiving 40 mg Coleus forskohlii/kg/day for 10 days before partial hepatectomy. The treatments were performed by gastric gavage. After the surgical procedure, treatment was continued according to the following groups: CG 24 h, CG 48 h, TG 24 h, and TG 48 hs, and liver tissue and intracardiac blood samples were obtained for histological and biochemical analysis, respectively. Results No significant differences were observed in mitotic or apoptotic index or in the concentrations of the enzymes AST, ALT and alkaline phosphatase, and no areas of fibrosis were detected. Conclusion Treatment with Coleus forskohlii did not interfere with the course of hepatic hyperplasia.

ABSTRACT

BACKGROUND/AIMS: The serum aminotransferase level is usually elevated in rhabdomyolysis, and these enzymes originate from the skeletal muscle. On the other hand, there is limited data showing whether the degree of elevation of these enzymes differs according to the concurrent liver disease.METHODS: Patients with rhabdomyolysis were selected when their serum creatinine kinase level was >1,000 U/L. They were categorized as the group with and without concurrent liver disease. The AST and ALT levels in both groups were compared. In addition, the aminotransferase level was compared between those with rhabdomyolysis and those with alcoholic liver disease.RESULTS: Among the 165 patients with rhabdomyolysis, 19 had concurrent liver disease. The median peak AST was higher in the group with concurrent liver disease (332 U/L [interquartile range (IQR), 127–1,604] vs. 219 U/L [IQR, 115–504]). In addition, the median peak ALT was higher in the group with concurrent liver disease (107 U/L [IQR, 74–418] vs. 101 U/L [IQR, 56–218]). On the other hand, there was no significant difference in both enzymes between the two groups. The median peak AST level was significantly higher in those with rhabdomyolysis than in those with alcoholic liver disease (221 U/L [IQR, 118–553] vs. 103 U/L [IQR, 59–206]), but the median peak ALT was not significantly different (102 U/L [IQR, 58–222] vs. 51 U/L [IQR, 26–117]).CONCLUSIONS: Rhabdomyolysis showed an elevated AST-dominant aminotransferase level, which is not different according to concurrent liver disease. Therefore, it is recommended that rhabdomyolysis be considered first in cases of elevated aminotransferase levels in patients with a suspicious skeletal muscle injury.

ABSTRACT

ABSTRACT INTRODUCTION: Dengue virus (DENV) infection has been considered a major public health problem in tropical countries. The unavailability of serologic testing in public health centers might adversely impact patients' outcome. OBJECTIVE: This study aimed to evaluate the accuracy of mean platelet volume (MPV) and aspartate aminotransferase (AST) to platelet ratio index (APRI) as laboratory markers of DENV infection that could be used to differentiate primary and secondary infections. METHODS: We assessed laboratory results from 503 patients with positive rapid test for DENV infection. RESULTS: Severe thrombocytopenia and increased liver involvement were observed in patients with DENV heterotypic secondary infection. Our data suggest that APRI was able to distinguish patients with primary and secondary infection (p = 0.006) with a relevant sensitivity (75%), specificity (76%) and a cut-off of 1.06. A total of 80 out of 105 (76%) patients with primary DENV infection had APRI ≤ 1.06, and 12 (75%) with secondary DENV infection had APRI > 1.06. On the other hand, MPV did not show significance in the differentiation of types of infection, coming up with poor area under the receiver operating characteristic (ROC) curve (0.61). CONCLUSION: APRI seems to be a powerful tool for early identification of DENV secondary infection cases in health centers.


RESUMO INTRODUÇÃO: A infecção pelo vírus da dengue (DENV) é considerada um grande problema de saúde pública nos países tropicais. A indisponibilidade de testes sorológicos em centros de saúde pública pode afetar negativamente o prognóstico do paciente. OBJETIVO: Este estudo teve como objetivo avaliar a precisão do volume médio de plaquetas (MPV) e o índice da relação de aspartato aminotransferase (AST) sobre plaquetas (APRI) como marcadores laboratoriais de infecção por DENV, que poderiam ser utilizados para diferenciar infecções primárias e secundárias. MÉTODOS: Foram avaliados os resultados laboratoriais de 503 pacientes com teste rápido positivo para infecção por DENV. RESULTADOS: Foram observadas trombocitopenia grave e disfunção hepática em pacientes com infecção secundária heterogênea por DENV. Nossos dados sugerem que o APRI foi capaz de distinguir os pacientes com infecção primária e secundária (p = 0, 006), com relevante sensibilidade (75%) e especificidade (76%) e corte de 1, 06. Um total de 80 de 105 (76%) pacientes com infecção primária por DENV tinha APRI ≤ 1, 06; e 12 (75%) com infecção secundária por DENV, APRI > 1, 06. Por outro lado, o MPV não mostrou significância na diferenciação de tipos de infecção, apresentando baixo valor da área sob a curva de característica de operação do receptor (ROC) (0, 61). CONCLUSÃO: APRI parece ser uma ferramenta poderosa para identificação precoce de casos de infecção secundária de DENV em centros de saúde.

ABSTRACT

Abstract Purpose: To investigate the effects of capsiate treatment on hepatic hyperplasia in partially hepatectomized rats. Methods: The animals were divided into a Capsiate group (CPH), a Capsiate Post-Partial Hepatectomy group (CPPH) and a Partial Hepatectomy Control group (PH). CPH and CPPH animals received 60 mg/kg/day Capsiate for 30 days. Next, the rats underwent partial hepatectomy. CPPH animals continued to receive treatment for 48 h after partial hepatectomy. Liver tissue and intracardiac blood samples were obtained 24 or 48 h after PH. Results: Capsiate treatment interfered with hepatic parameters, reducing the number of mitoses and apoptosis and increasing blood ALT and alkaline phosphatase concentrations. Conclusion: Capsiate treatment preceding hepatic surgery may compromise the initial period of postoperative recovery.

ABSTRACT

We studied the toxic effects of a Sarcocystis hirsuta cyst extract fed to mice. Degenerative changes were found in mice gavage-fed fresh, frozen, and heat-treated S. hirsuta cyst extract. There were increases in the levels of serum aspartate aminotransferase and alanine aminotransferase as well as hepatic and brain malondialdehyde (MDA) levels along with concomitant decreases in catalase (CAT) and superoxide dismutase (SOD) activities of mice receiving fresh and frozen S. hirsuta extracts. Gavage feeding of heat-treated S. hirsuta cyst extract had no effects on liver enzymes or brain MDA content, but the liver MDA level did increase. Mice in the heat-treated cyst group showed reduced CAT and SOD activities as well as increased hepatic MDA levels compared to those in the control group. These results indicate that an extract of S. hirsuta cyst can induce oxidative stress and hepatic injury, even after heat treatment.

ABSTRACT

BACKGROUND: Pyridoxal-5'-phosphate (P5P), a coenzyme of the aspartate aminotransferase (AST) and alanine aminotransferase (ALT) reactions, is required to measure aminotransferase levels (IFCC method). However, a modified IFCC method that uses a reagent devoid of P5P is commonly used in laboratories in Korea. To determine the differences between the two methods, we compared aminotransferase levels measured by using the IFCC method and modified IFCC method. METHODS: Serum levels of AST and ALT, with and without P5P, were measured in 2,318 patients. Based on the allowable limits of performance set by the Royal College of Pathologists of Australasia (RCPA), differences between the two methods were analyzed under various conditions. RESULTS: Higher AST and ALT values were obtained by the IFCC method compared to modified IFCC method, showing significant differences between the two methods (AST, 5.8±14.2 IU/L; ALT, 2.8±6.9 IU/L) (P<0.001). Values exceeding RCPA criteria were more frequently observed in emergency orders (AST, 65.8%; ALT, 14.4%) than in routine orders (AST, 3.2%; ALT, 9.6%), as well as in inpatient wards (AST, 70.4%; ALT, 18.5%) compared to outpatient clinics (AST, 56.6%; ALT, 10.0%). However, the differences between the two methods were not significant among the disease groups, except for the acute myocardial infarction group. CONCLUSIONS: The method using reagents without P5P underestimated aminotransferase activity. The effect of P5P was more significant in patients with acute myocardial infarction, considered as P5P-deficient. In conclusion, the IFCC method with P5P should be applied for measuring AST and ALT serum levels.

ABSTRACT

OBJECTIVES: Although mercury (Hg) exposure is known to be neurotoxic in humans, its effects on liver function have been less often reported. The aim of this study was to investigate whether total Hg exposure in Korean adults was associated with elevated serum levels of the liver enzymes aspartate aminotransferase (AST), alanine transaminase (ALT), and gamma-glutamyltransferase (GGT). METHODS: We repeatedly examined the levels of total Hg and liver enzymes in the blood of 508 adults during 2010-2011 and 2014-2015. Cross-sectional associations between levels of blood Hg and liver enzymes were analyzed using a generalized linear model, and nonlinear relationships were analyzed using a generalized additive mixed model. Generalized estimating equations were applied to examine longitudinal associations, considering the correlations of individuals measured repeatedly. RESULTS: GGT increased by 11.0% (95% confidence interval [CI], 4.5 to 18.0%) in women and 8.1% (95% CI, -0.5 to 17.4%) in men per doubling of Hg levels, but AST and ALT were not significantly associated with Hg in either men or women. In women who drank more than 2 or 3 times per week, AST, ALT, and GGT levels increased by 10.6% (95% CI, 4.2 to 17.5%), 7.7% (95% CI, 1.1 to 14.7%), and 37.5% (95% CI,15.2 to 64.3%) per doubling of Hg levels, respectively, showing an interaction between blood Hg levels and drinking. CONCLUSIONS: Hg exposure was associated with an elevated serum concentration of GGT. Especially in women who were frequent drinkers, AST, ALT, and GGT showed a significant increase, with a significant synergistic effect of Hg and alcohol consumption.

ABSTRACT

Objective To investigate the feasibility of alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ratio in predicting the degree of hepatic steatosis in chronic hepatitis C (CHC) patients.Methods A total of 231 CHC patients who visited The First People's Hospital of Nanyang from May 2012 to June 2016 were enrolled,among whom 105 (45.45%) had nonalcoholic fatty liver disease (NAFLD) and 126 (54.55%) did not have NAFLD.According to the ultrasound score,the NAFLD group was divided into mild-to-moderate (1-2 points) hepatic steatosis group (n =67) and severe (3 points) hepatic steatosis group (n =38).The two groups were compared in terms of demographic data and disease data including creatinine,fasting blood glucose,ALT,AST,ALT/AST ratio,γ-glutamyltransferase (GGT),uric acid,low-density lipoprotein,high-density lipoprotein (HDL),cholesterol (CHO),and triglyceride (TG) to screen out independent risk factors for NAFLD in CHC patients.The independent samples t-test was used for comparison of normally distributed continuous data between groups,and the Wilcoxon rank sum test was used for comparison of non-normally distributed continuous data between groups;the chi-square test was used for comparison of categorical data between groups;with severe NAFLD as the dependent variable,different factors were introduced into the logistic regression equation to screen out independent risk factors.Results Compared with the non-NAFLD group,the NAFLD group had significantly higher systolic pressure,diastolic pressure,fasting blood glucose,ALT/AST ratio,and levels of ALT,GGT,HDL,CHO,and TG,as well as a significantly higher proportion of patients with diabetes,hypertension,or metabolic syndrome (all P < 0.05).Compared with the severe hepatic steatosis group,the mild-to-moderate hepatic steatosis group had significantly lower systolic pressure,diastolic pressure,fasting blood glucose,ALT/AST ratio,and levels of ALT,GGT,HDL,CHO,and TG,as well as a significantly lower proportion of patients with diabetes,hypertension,or metabolic syndrome (all P < 0.05).The logistic regression analysis showed that metabohc syndrome,ALT,and ALT/AST ratio were independent risk factors for NAFLD (all P <0.05),and metabolic syndrome,ALT,ALT/AST ratio,and GGT were independent risk factors for severe NAFLD (all P < 0.05).Conclusion ALT/AST ratio is an independent risk factor for NAFLD in CHC patients and has a certain value in evaluating the degree of NAFLD.

ABSTRACT

We report an asymptomatic 23-year-old woman with an isolated and persistent increase in serum levels of aspartate aminotransferase (AST). An extensive work up including laboratory and image testing revealed no abnormalities thus suggesting the presence of macro-AST. A polyethylene glycol (PEG) precipitation assay was performed and confirmed the presence of macro-AST.

ABSTRACT

Objective To explore the pathogenesis of ischemic preconditioning to warm ischemia reperfusion injury of hepatocytes in rats. Methods Ninety SD rats were randomly divided into three experimental groups:sham operation group (group A), warm hepatic ischemia/reperfusion group(group B and group C). Group C was given ischemic preconditioning treatment. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected 0 h, 2 h, 6 h, 12 h and 24 h after ischemia reperfusion injury. Levels of TNF-α and IL-1β were tested detected by ELISA. Levels of malondialdehyde (MDA) and superoxide dismutase (SOD) of hepatocytes were detected at the same time points. Mitochondrial membrane potential was examined to assess ischemia reperfusion injury of hepatocytes in rats using chart of intensity of JC-1 in mitochondria. Results The serum levels of ALT, TNF-α, IL-1β, and MDA were significantly higher in hepatic warm ischemia reperfusion group and ischemic preconditioning group than those in sham operation group (P<0.05). Values of prothrombin activity and cholinesterase were significantly lower in liver warm ischemia reperfusion group and ischemic preconditioning group than those of sham operation group (P<0.05). The SOD level of liver was significantly lower in warm ischemia reperfusion group and ischemic preconditioning group than that in sham operation group. The indexes were better in ischemic preconditioning group than those of warm ischemia reperfusion group (P<0.05). The mitochondrial membrane potential level of liver cells reached the lowest value 0 hours after ischemia and reperfusion, and then increased gradually within 24 hours (P<0.05). And the level of mitochondrial membrane potential of liver cells was significantly higher in ischemic preconditioning group than that in warm ischemia reperfusion group (P<0.05). Conclusion Ischemic preconditioning may play a protective role in warm ischemia-reperfusion injury in rats. Ischemic preconditioning may significantly decrease the levels of ALT, AST, TNF-α, IL-1βand MDA, and increase the SOD activity in hepatocytes. Thedamage of mitochondrial membrane potential is decreased after ischemic preconditioning, which might be the pathogenesis of ischemic preconditioning to warm ischemia reperfusion injury of hepatocytes in rats.

ABSTRACT

Introducción: la enfermedad celíaca es una enfermedad autoinmune provocada por la ingestión de gluten que afecta aproximadamente al 0,5%-1% de la población mundial. Las señales extraintestinales incluyen elevados niveles de alanina-aminotransferasa (ALT). Objetivo: evaluar los efectos de una dieta libre de gluten en los niveles ALT en pacientes con enfermedad celíaca. Métodos: este estudio transversal se llevó a cabo en la clínica ambulatoria de gastroenterología de un hospital universitario. Resultados: se incluyeron veintiséis pacientes con enfermedad celíaca con edad de 34,1 ± 11,4 años; 15,4% fueron hombres. Los sujetos del estudio tenían un nivel promedio de ALT de 54,6 ± 36,3 (mediana 40,5) U/L. Hubo una mayor proporción de individuos con hepatitis B en el grupo con ALT ≥50 U/L en comparación con sujetos con ALT <50 U/L. Entre los pacientes evaluados después del tratamiento con dieta libre de gluten se observó una reducción significativa de los valores de ALT (36,0 versus 31,0 U/l; p= 0,008). Conclusión: el treinta y cinco por ciento de los pacientes con enfermedad celíaca tenía ALT por encima del tercil superior. Se encontraron niveles más altos de ALT en pacientes con hepatitis viral B y en aquéllos que no se adhirieron a la dieta. Hubo una reducción de aminotransferasas como resultado de una dieta libre de gluten.


Introduction: Celiac disease is an autoimmune disease triggered by ingestion of gluten. It affects approximately 0.5% to 1% of the world population. Extra intestinal manifestations include elevated alanine aminotransferase (ALT) levels. Objective: The objective of this study was to evaluate the effects of a gluten-free diet on ALT levels in patients with celiac disease. Methods: This cross-sectional study was conducted in the gastroenterology outpatient clinic of a university hospital. Results: Twenty-six patients with celiac disease were included. Average patient age was 34.1 ± 11.4 years, and 15.4% of the patients were men. Study subjects had a mean ALT level of 54.6 ± 36.3 U/L (median 40.5). There was a higher proportion of individuals with hepatitis B in the group with ALT ≥ 50 U/L than in the group of subjects with ALT < 50 U/L. Among patients tested after treatment with a gluten-free diet, we observed a significant reduction in ALT values (36.0 vs. 31.0 U/L; P = 0.008). Conclusion: Thirty-five percent of celiac disease patients had ALT levels above the upper tertile. Higher ALT levels were found in patients with viral hepatitis B and in those who do not adhere to the diet. There was a reduction of aminotransferases with a gluten-free diet.

ABSTRACT

Objective To investigate the protective effects of Trimetazidine(TMZ)on the ischemia reperfusion injury (IRI)of fatty liver in autotransplantation model. Methods Fatty liver model was established by feeding high fat diet. Male Wistar rats (n=30) were randomized into three groups;Sham group, TMZ group and Model group. Liver was autotransplanted in both TMZ group and Model group. Serum levels of ALT, SOD, MDA, Bcl-2 and activated Caspase-3 were assessed 6 hours after the operation. The pathological performances of liver were also determined. Results Compared with the Model group, serum levels of ALT,AST, MDA and SOD levels decreased significantly in the TMZ group(P<0.05). Serum level of Bcl-2 was higher while level of activated Caspase-3 was lower in TMZ group than those in Model group(P<0.05). Histo?logical assay and TUNEL staining showed reduced hepatocyte swelling and narrowed sinusoid as well as decreased hepatic apoptosis in TMZ group compared with Model group. Conclusion TMZ can reduce oxidative stress, promote the expression of Bcl-2 and inhibit the activation of Caspase-3, which all contribute to its protective effect on fatty liver with ischemia-re?perfusion injury.
