ABSTRACT
Abstract Background Previous studies have suggested that systemic metabolic abnormalities are closely related to psoriatic arthritis (PsA). Gamma-glutamyl transpeptidase (GGT) and indirect bilirubin (IBIL), two essential active substances in hepatic metabolism that have been demonstrated as an oxidative and anti-oxidative factor respectively, have been proved to be involved in oxidative stress damage and inflammation in several human diseases. However, their role in PsA remains unclear. Methods In this retrospective comparative cohort study, a case group of 68 PsA patients and a control group of 73 healthy volunteers from the Third Hospital of Hebei Medical University were enrolled. Serum GGT, IBIL, GGT/IBIL ratio and C-reactive protein (CRP), a well applied bio-marker of systemic inflammatory in PsA, were compared between the two groups. Furthermore, the relationship of GGT, IBIL and GGT/IBIL with CRP were explored in PsA patients. Finally, the patients were divided into high inflammation group and low inflammation group according to the median value of CRP. Multivariate logistic regression analyses were used for the association of systemic inflammation level with GGT, IBIL and GGT/IBIL. Results Compared with healthy controls, PsA patients exhibited significantly higher serum GGT, GGT/IBIL, and CRP levels and lower IBIL levels. Serum GGT and GGT/IBIL were positively correlated with CRP, whereas IBIL were negatively correlated with CRP. Binary logistic regression analysis revealed that serum GGT was a risk factor for high CRP in PsA, whereas IBIL was a protective factor. Furthermore, GGT/IBIL was a better indicator of high CRP condition in PsA patients than either GGT or IBIL alone, as determined by the receiver operating characteristic curves. Conclusion GGT and IBIL may participate in the pathogenesis of PsA. Additionally, GGT, IBIL and the balance of the two may reflect systemic inflammation mediated by oxidative stress events related to metabolic abnormalities to a certain extent.
ABSTRACT
Background: Identifying patients at risk with Non-alcoholic fatty liver disease (NAFLD) related fibrosis is crucial. Many noninvasive fibrosis markers were developed recently in chronic hepatitis C and B patients, but a few were evaluated in NAFLD. Aim: to assess the accuracy of the gamma-glutamyl transpeptidase and the other noninvasive markers gamma-glutamyl transpeptidase-to-platelet ratio and gammaglutamyl transpeptidase-to-albumin ratio (GPR and GAR) versus fibroscan as indicators of hepatic fibrosis in NAFLD patients. Patients and Methods: A total of 100 NAFLD patients were examined by abdominal ultrasound and then fibroscan to assess liver steatosis and fibrosis. They were grouped into the early fibrosis group and the advanced fibrosis group. Demographic data and laboratory investigation were collected. GPR and GAR were calculated. The correlation between them and liver stiffness measurement (LSM) was reported. The accuracy of predicting liver fibrosis was assessed. Results: There was a significant positive correlation between GPR and GAR and the degree of fibrosis. GPR (P <0.001*) and GAR (P <0.001*) were independent predictors for advanced hepatic fibrosis by multiple linear regression analysis. Fibrosis score was used as the dependent variable, with the other studied biomarkers as independent variables. The AUCs of GPR and GAR were 0.790 and 0.949 in assessing liver fibrosis, respectively. Conclusion: GPR and GAR were positively correlated with hepatic fibrosis and may be used as a novel, simple, accurate, and low-cost parameter for diagnosing hepatic fibrosis in NAFLD patients.

Objective:To explore the association between glutamyl transpeptidase (GGT) trajectories and new-onset metabolic syndrome to provide insights for the prevention and treatment of metabolic syndrome.Methods:A total of 3 209 subjects who met the inclusion criteria were enrolled in the study cohort of physical examination population. The GGT levels before follow-up were classified by R LCTMtools program into 3 GGT trajectory groups: low-stable group, medium-stable group and high-stable group. Cox proportional hazards regression model was used to analyze the correlation between different GGT trajectories and new-onset metabolic syndrome.Results:At the end of follow-up in 2020, the cumulative incidence of metabolic syndrome was 7.0%, and the incidence of metabolic syndrome in the low-stable group, medium-stable group and high-stable group were 3.9%, 11.4%, and 15.0%, respectively, showing a growth trend ( P<0.001). After adjusting for multiple confounding factors by Cox proportional hazards regression model, the risk of metabolic syndrome in medium-stable group and high-stable group increased in the total population. The hazard ratios (95% CI)for the high stable group in males and the medium-stable group in females were 1.67(1.07-2.60) and 3.29(1.14-9.53), respectively, compared with their respective low-stable group. Conclusion:Elevated longitudinal trajectory of GGT is a risk factor for new-onset metabolic syndrome, the risk of metabolic syndrome in the total population increased with the increase of long-term GGT level. It is recommended to maintain the long-term level of GGT at about 28 U/L in males and 14 U/L in females, respectively, to achieve the goal of early prevention of metabolic syndrome.
ABSTRACT
SUMMARY OBJECTIVE: Gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index are three systemic immune and inflammation indexes that were investigated for their diagnostic and prognostic proficiencies in cardiovascular diseases and cancers. However, their predictive values for invasive aspergillosis have not yet been studied. The aim of this study was to evaluate Gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index levels and their diagnostic values in invasive aspergillosis. METHODS: A total of 23 patients with invasive aspergillosis and 23 sex- and age-matched healthy participants were included in this study. Complete blood count parameters and liver function tests were studied. Gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index were calculated. RESULTS: Leukocyte, neutrophil, lymphocyte, and monocyte levels were statistically significantly higher in IA group (p=0.031, p=0.027, p=0.033, and p=0.001, respectively). In invasive aspergillosis group, platelets were numerically lower; Aspartate transaminase, alanine aminotransferase, and lactic dehydrogenase levels were numerically higher than those in control group but differences between levels were not statistically significant (p>0.05). The γ-glutamyl transpeptidase levels of patients were statistically significantly higher (p=0.007), and in addition, statistically significant differences were found between groups in terms of gamma-glutamyl transpeptidase-platelet ratio, system inflammation response index, and systemic immune inflammation index (p<0.001, p=0.037, p=0.001, respectively). Receiver operating characteristic analysis was performed, and areas under the curves were evaluated. gamma-glutamyl transpeptidase-platelet ratio had the higher area under the curve than systemic immune inflammation index and system inflammation response index (AUC 0.849, 0.798, 0.693, respectively). The results from receiver operating characteristic analysis of the data suggested that the use of a cutoff value of 0.15 for gamma-glutamyl transpeptidase-platelet ratio would be optimum for clinical use to confirm independent predictors of patients with invasive aspergillosis. CONCLUSIONS: Gamma-glutamyl transpeptidase-platelet ratio is an independent, a useful predictor, and is superior to other evaluated markers in the diagnosis of inflammation in invasive aspergillosis. Gamma-glutamyl transpeptidase-platelet ratio may also be a helpful biomarker for clinicians to follow-up the inflammatory process of these patients.

Introducción: El ozono médico tiene eficacia clínica e incrementa la relación beneficio/riesgo en pacientes con artritis reumatoide tratados con la terapia combinada metotrexate + ozono. Hoy, la gamma glutamil transferasa se considera como un marcador de riesgo de enfermedades de una alta morbilidad y mortalidad, y tiene particular valor en la artritis reumatoide por desempeñar un papel patológico asociado al estrés oxidativo y a la remodelación ósea, lo que causa daño al cartílago y al hueso. Objetivo: Evaluar los efectos del ozono médico sobre los niveles de gamma glutamil transferasa. Métodos: Se estudiaron pacientes portadores de dos enfermedades artríticas: artritis reumatoide (n = 100; grupo tratado con metotrexate [n = 50] y grupo con metotrexate + ozono [n = 50]) y osteoartritis de rodilla (n = 40; grupo precondicionado con ozono antes de la artroscopía [n = 20] y grupo sin pretratamiento con ozono antes de la artroscopía [n = 20]). Los pacientes con artritis reumatoide fueron valorados con indicadores clínicos específicos, incluidos los niveles de anticuerpos contra péptidos cíclicos citrulinados, así como las concentraciones de glutatión reducido, importante antioxidante endógeno. Resultados: El ozono médico reguló la actividad sérica de gamma glutamil transferasa. Correlacionó de forma inversamente proporcional con los niveles de glutatión reducido que, a su vez, fue el único marcador redox que para los pacientes tratados con la terapia combinada metotrexate + ozono fue directamente proporcional con todas las variables clínicas evaluadas. Conclusión: Se debe considerar a la gamma glutamil transferasa un indicador de la eficacia clínica del ozono médico en las enfermedades estudiadas, por su doble función: biomarcador de estrés oxidativo e indicador de la remodelación patológica del hueso(AU)
Introduction: Medical ozone has demonstrated its clinical efficacy as well as the increase of beneficial/risk relationship in rheumatoid arthritis patients treated with metotrexate+ozone combined therapy. At present, gamma-glutamyl transpeptidase is considered as risk indicator of high morbimortality diseases. It has a special value in arthritis diseases due to its pathologic role associated to oxidative stress and in the abnormal bone remodeling processes. Objective: Assess the ozone medical effects on gamma-glutamyl transpeptidase levels. Method: Patients who suffered of two arthritic diseases: rheumatoid arthritis (n=100; Group treated with Metotrexate (n=50) and metotrexate+ozone (n=50) and knee osteoarthritis (n=40); Group preconditioned with ozone before arthroscopy (n=20) and Group without previous treatment with ozone before arthroscopy (n=20). Rheumatoid arthritis patients were assessed through specific clinic indicators which included antibodies against cyclic citrullinate peptides as well as reduced gluthatione concentrations which are an important endogenous antioxidant. Results: Medical ozone regulated serum gamma-glutamyl transpeptidase activity which correlated in inverse proportion to reduced glutathione levels which was the only one redox marker that correlated with all clinical variables (p < 0.05) when patients were treated with metotrexate+ozone. Conclusion: Gamma-glutamyl transpeptidase should be considered as biomarker of medical ozone clinical efficacy in rheumatoid arthritis and knee osteoarthritis due to GGT´s both pathologic functions: indicator of oxidative stress and abnormal bone remodeling processes(AU)

Objective: To explore the application value of shear wave elastography (SWE) and γ-glutamyl transpeptidase/platelet ratio (GPR) in diagnosis of liver fibrosis in chronic hepatitis B (CHB) patients. Methods: A total of 116 patients with CHB were collected. SWE examinations and blood routine and liver function tests were performed before liver biopsy. Liver hardness measurement (LSM) was recorded, and GPR was calculated. According to the Metavir scoring system, liver fibrosis was classified as F0, F1, F2, F3 and F4 in the pathologic examinations. The correlations of SWE, GPR and liver fibrosis stages were analyzed. Receiver operating characteristic curve (ROC) was drawn, and Elast PQ and GPR for diagnosis of liver fibrosis in patients with CHB were compared. The diagnostic value of Elast PQ of liver fibrosis in patients with ALT below 2 times of the upper limit of normal (ULN) value was analyzed. Results: Elast PQ and GPR were all positively correlated with liver fibrosis staging (r=0.94, P<0.01; r=0.92, P<0.01). The diagnostic efficiency of Elast PQ was superior to that of GPR for F1-F3 fibrosis stages (Z=2.21, P=0.03; Z=2.16, P=0.03; Z=2.27, P=0.02), of Elast PQ in patients with ALT≤1×ULN was better than that in patients with 1×ULN
ABSTRACT
Resumen: ANTECEDENTES: Las concentraciones elevadas de gamma-glutamil transpeptidasa (GGT) se han asociado con el riesgo de enfermedad coronaria isquémica, diabetes mellitus tipo 2 y evento vascular cerebral. OBJETIVO: Determinar mediante métodos estadísticos estandarizados que la elevación sérica de gamma-glutamil transpeptidasa es predictor temprano de evento vascular cerebral en la población mexicana. MATERIAL Y MÉTODO: Estudio tipo casos y controles, con medición de GGT sérica en pacientes con enfermedades crónico-degenerativas en control y pacientes crónicos con un evento cardiovascular adverso, en este caso, un evento vascular cerebral de tipo isquémico (EVC), efectuado de mayo de 2016 a julio de 2017. RESULTADOS: Se incluyeron 74 pacientes; los pacientes con EVC tuvieron, en pro- medio, 17.81 U/L de GGT más que los controles ajustado por edad, con diferencia estadísticamente significativa (p = 0.038, IC95% 1.04-34.57). CONCLUSIONES: Las concentraciones de gamma-glutamil transpeptidasa se correlacionan de manera directamente proporcional con el riesgo cardiovascular, lo que tiene gran importancia debido a que se ha demostrado que sus concentraciones séricas pueden disminuirse con medidas como dieta y ejercicio, por lo que se abre un amplio panorama para posteriores estudios que puedan reafirmar la validez de éste y hacer otros con un enfoque preventivo.
Abstract: BACKGROUND: Elevated levels of gamma-glutamyl transpeptidase (GGT) have been associated with the risk of ischemic heart disease, diabetes mellitus and stroke. OBJECTIVE: To determine, by means of standardized statistical methods, that the serum elevation of GGT is an early predictor of ischemic stroke in the Mexican population. MATERIAL AND METHOD: A case-control study was conducted with measurement of serum GGT in patients with chronic-degenerative diseases without cardiovascular events and chronic patients with an adverse cardiovascular event, in this case, an ischemic stroke, done from May 2016 to June 2017. RESULTS: A total of 74 patients were analyzed; patients with ischemic stroke presented, on average, 17.81 U/L of GGT more than controls adjusted for age, with a statistically significant difference (p = 0.038, 95%CI 1.04- 34.57). CONCLUSIONS: GGT levels correlated directly with cardiovascular risk, which is of great importance, since it has been shown that serum levels can be reduced with measures such as diet and exercise, so that a broad panorama opens up for further studies that can reaffirm the validity of this study and do others with a preventive approach.
ABSTRACT
Objective: To investigate the diagnostic efficiency of γ-glutamyl transpeptidase to platelet ratio (GPR) for detecting liver fibrosis in chronic hepatitis B patients, and to compare its efficiency with those of liver stiffness measurement (LSM) value, asperate aminotransferase to platelet ratio index (APRI) and fibrosis-4 index (FIB-4). Methods: We retrospectively included patients with chronic hepatitis B who had undergone surgery or liver biopsy in our hospital from May 2015 to Sep. 2015. All patients had undergone transient elastography to record LSM value and serological examination to calculate GPR, APRI and FIB-4 before surgery or liver biopsy. The diagnostic efficiency of each index was evaluated by receiver operating characteristic (ROC) curve and the area under ROC curve was compared. Results: Totally 260 patients were eventually enrolled in the present study, including 213 males and 47 females, with the average age being (53.49±9.78) years and the average BMI being (23.36±3.06) kg/m2. GPR, LSM value, APRI and FIB-4 were moderately correlated with S≥2 and S4 liver fibrosis (all P0.05). Conclusion: It has been indicated that GPR, LSM value, APRI and FIB-4 have diagnostic accuracy for S≥2 and S4 liver fibrosis. The diagnostic accuracy of LSM value and GPR for S≥2 and S4 liver fibrosis is better than that of FIB-4, and that of LSM value for S4 liver fibrosis is better than that of APRI. Therefore, GPR and LSM value may serve as the optimal indexes for noninvasively evaluating liver fibrosis in chronic hepatitis B patients.

ABSTRACT
Objective To explore the association between ratio index of gamma glutamyl transpeptidase/platelet (GPRI) and the prognosis of patients with hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) before liver resection. Methods A total of 368 patients underwent liver resection for HBV-related HCC were retrospectively analyzed in this study. Patients were divided into high GPRI group (n=184, GPRI≥0.38) and low GPRI group (n=184, GPRI<0.38). Clinicopathologic characteristics including overall survival (OS) and disease-free survival (DFS) were compared between the two groups. Independent risk factors influencing DFS and OS were determined by Cox multivariate analysis. Results Compared to low GPRI group, there were higher levels of serum total bilirubin and alanine aminotransferase, higher proportions of tumor diameter larger than 10 cm, amount of tumou more than 3, and patients with macrovascular invasion and intermediate or advanced HCC in high GPRI group (all P<0.05). Values of DFS at 1, 3, and 5 years were significantly lower in high GPRI group (50.8%, 16.9%and 5.7%) than those in low GPRI group (69.0%, 33.3%, 10.7%;P=0.001). Values of OS at 1, 3, and 5 years were also significantly lower in high GPRI group (75.0%, 51.8%and 36.0%) than those in low GPRI group (89.8%, 72.8%and 63.2%;P<0.05). Cox multivariate analysis also demonstrated that GPRI ≥0.38 was an independent risk factor for DFS and OS in patients with HBV-related HCC after liver resection. Conclusion Preoperative GPRI can predict tumor recurrence and long-term survival in patients with HBV-related HCC after liver resection.
ABSTRACT
Objective To analyze the association of serum γ-glutamyl transpeptidase(γ-GT)level with carotid intima media thickness(IMT) in essential hypertension.Methods All the 300 essential hypertension patients and 70 healthy controls were from Ganzhou People′s Hospital.They were divided into healthy control group(70 cases),hypertension with out arteriosclerosis group(141 cases) and hypertension with arteriosclerosis group(159 cases) based on carotid IMT.Fasting blood glucose,serum lipid,routine laboratory tests,hepatic and renal function were detected by routine methods.The one-way analysis of variance and χ2-test were used to compared among the three groups,and the relationship of γ-GT with IMT was assessed by using the Spearman correlation coefficient,multiple linear regressions and Logistic regression analysis.Results The diastolic blood pressure,body mass index,fasting blood glucose,glomerular filtration rate and glycosylated hemoglobin had no differences among the three groups(P>0.05),but systolic pressure,triacylglycerol,total cholesterol,high density lipoprotein cholesterol,aspartate transaminase(AST),low density lipoprotein cholesterol alanine,transaminase(ALT) and γ-GT had significant differences among the three groups(P<0.05).Multiple linear regression analysis showed that the serum γ-GT(β=-0.345,95%CI was-0.005——0.511,P=0.036) was also negatively correlated with IMT,and Logistic regression analysis showed that γ-GT(OR=0.569,95%CI was 0.237-0.867,P=0.029)was a protective factor for atherosclerosis.Conclusion Our study demonstrated the level of γ-GT is negative with IMT among essential hypertension patients,and monitoring the changes of serum liver enzyme might has significant effect on the early detection of arteriosclerosis.
ABSTRACT
Objective To analyze the association of serumγ-glutamyl transpeptidase (GGT) level with kidney function in essential hypertension patients.Methods 500 patients with essential hypertension were selected.They were divided into high glomerular filtration rate (GFR) group,normal renal function group,mild renal function decline group,and moderate or severe renal function decline group based on GFR.The fasting blood glucose,serum lipid,routine laboratory tests,hepatic and renal function were detected by routine methods.The one way ANOVA test was used to show differences among groups,and the relationship of serum GGT with GFR was assessed by using the Pearson correlation coefficient and multiple linear regressions.Results There were 500 hypertension patients [(56.03 ±7.38)years old,240 males and 260 females] enrolled in this study.Among them,43 (23/20) cases were in the high GFR group,161 (82/79) cases were in the normal renal function group,219(105/114) cases were in the mild renal function decline group,and 77 (30/47) cases were in the moderate or severe renal function decline group.The sex,blood pressure,heart rate,body mass index,fasting blood glucose,blood lipid level had no statistically significant differences among the groups (all P ＞ 0.05),but the age,aspartate transaminase (AST),alanine transaminase (ALT) and GGT had statistically significant differences among the groups (all P ＜ 0.05).Pearson correlation analysis showed:age (r =0.278,P =0.002) was negatively associated with GFR,while AST (r =0.159,P =0.003),ALT (r =0.352,P ＜ 0.001) and GGT(r =0.237,P ＜ 0.001) were positively correlated with GFR.Multiple linear regression analysis showed that the serum GGT (β =0.146,95％ CI 0.099,0.282,P ＜0.001) was also positively correlated with GFR.Conclusion Our study demonstrated that the level of GGT was positively correlated with GFR in essential hypertension patients,and monitoring the changes of serum GGT may have significant effect on kidney function.

Objective To analyze the relationship and clinical meaning of serumglutamyl transpeptidase (GGT) level with left atrial diameter.Methods All the 320 essential hypertension patients from Ganzhou People′s Hospital were divided into normal left atrial group and enlarged left atrial group based on the size of left atrial diameter.Fasting blood glucose,serum lipid,routine laboratory tests,hepatic and renal function and blood pressure were measured by routine methods,and used for analyzing between groups.Results Among essential hypertension patients,the GGT level in enlarged left atrial group [(24.78±10.93)U/L] was lower than normal left atrial group[(35.23±12.46)U/L] (P=0.004).Multiple linear regression analysis showed that the serum GGT was negatively correlated with left atrial diameter (P=0.032),and logistic regression analysis showed that GGT was a protective factor for enlarged left atrial (OR=0.424,P=0.026).Conclusion Our study demonstrated the level of GGT was negatively with left atrial diameter among essential hypertension patients,and monitoring the changes of serum liver enzyme may has significant effect on the early detection of enlarged left atrial diameter.
ABSTRACT
Objective To observe the changes of serumγ?glutamyl transpeptidase(GGT)levels before and after the patho?gen treatment in patients with subclinical schistosomiasis,and explore its clinical value in the diagnosis and treatment of sub?clinical schistosomiasis. Methods Totally 109 patients with subclinical schistosomiasis,who were found in the endemic inves?tigation of schistosomiasis in Ezhou City,were selected as the investigation subjects,and then they were treated with praziquan?tel. The serum GGT levels of the subjects before and after the treatment were detected and compared. Results Before the treat?ment,the average value of the GGT levels of the 109 patients was(48.1 ± 45.9)IU/L,among which,the GGT levels of 69 cases (63.3%)were normal,and the levels of 40 cases(36.7%)were increased. After the treatment,the average GGT level of the pa?tients was(32.1 ± 23.4)IU/L,which decreased by 33.3%comparing with that before the treatment,and the difference had a statistical significance(U=2.17,P=0.01). The GGT levels of 65 patients decreased in different degrees. Among the 40 pa?tients whose GGT levels had increased before the treatment,the GGT levels of 31 ones returned to the normal. Conclusion The GGT level detection can accurately reflect the liver function in the patients with subclinical schistosomiasis ,and also it has certain clinical application value to judge the liver function damage and recovery of the patients before and after the pathogen treatment.
ABSTRACT
Background: Acute pancreatitis is an important cause of morbidity and mortality worldwide. Alcohol and gallstone disease remain the commonest causes of acute pancreatitis but metabolic abnormalities, obesity and genetic susceptibility are thought to be increasingly important etiological factors. Serum enzymes amylases and lipase are used as conventional biomarkers of acute pancreatitis. Objectives: To assay serum enzymes amylase, lipase, adenosine deaminase (ADA) and gamma glutamyl transpeptidase (GGT) in acute pancreatitis of alcoholic and non-alcoholic etiology. The present study also aimed to find the correlation among the enzymes. Materials and methods: The study subjects were categorized as non-alcoholic acute pancreatitis (n=30), alcoholic acute pancreatitis (n=30) and healthy controls (n=30). Levels of amylase, lipase, adenosine deaminase and gamma glutamyl transpeptidase were estimated in serum samples by standard spectrophotometric methods. Results: The levels of amylase, lipase, ADA and GGT were significantly higher in acute pancreatitis patients than controls. With respect to amylase and lipase, more pronounced increase was seen in nonalcoholic than the alcoholic acute pancreatitis patients. Increase in GGT was more in alcoholic acute pancreatitis while increase in ADA was comparable in acute pancreatitis of alcoholic and non- Yerrajwala KS, Saradhini V, Reddy BR, Gudimella S. A study of Adenosine Deaminase and Gamma Glutamyl Transpeptidase in Acute Pancreatitis. IAIM, 2016; 3(3): 162-167. Page 163 alcoholic etiologies. Serum amylase showed significant positive correlation with lipase, GGT and ADA in alcoholic acute pancreatitis and with lipase in non-alcoholic acute pancreatitis. Conclusion: Serum levels of enzymes amylase, lipase, ADA and GGT served sensitive markers of acute pancreatitis. Future studies employing larger sample size and differentiating various etiologies of acute pancreatitis, findings correlation among enzyme biomarkers are required.
ABSTRACT
The crowd were divided to 3 groups according to glucose tolerance:normal glucose tolerance,impaired glucose regulation,and new type 2 diabetes,the data was analyzed.The result showed that as the severity of abnormal glucose metabolism,the serum GGT gradually advanced,early insulin secretion index descended,The levels of resistance index,fasting and postprandial blood sugar,and glycosylated hemoglobin all raised.The serum GGT and early insulin secretion index was inversely correlated.The higher GGT level was an independent risk factors of abnormal glucose metabolism.
ABSTRACT
The aim of the present study was to examine the causal-effect of baseline (year 2004) serum gamma-glutamyl transpeptidase (GGT) level with the prevalence of metabolic syndrome (MS) in year 2008. The study was comprised of male workers who underwent a regular health check-up in 2004 and 2008. MS was diagnosed according to the American Association of Clinical Endocrinologists (AACE) criteria. In the subgroup analysis according to serum GGT level, triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) showed a significant increasing tendency (p < 0.001). In addition, unexpectedly results were consistent in non-drinkers (p < 0.001). GGT level was significantly associated with risk factors of MS (waist circumference [WC]: r = 0.18, p < 0.001; fasting blood glucose [FBG]: r = 0.16, p < 0.001; TG: r = 0.29, p < 0.001). As the secondary biomarker, homeostasis model assessment of insulin sensitivity (HOMA-S) and TC had significant correlations with GGT level (HOMA-S: r = -0.14, p < 0.001; TC: r = 0.21, p < 0.001). In the 4-year prospective analysis, the predictive effect of baseline GGT concentrations on change in MS status was evaluated using Cox proportional model. Elevated GGT concentrations measured in 2004 were associated with the risk of MS incidence after 4 years (GGT: HR 1.7 [95% CI: 1.2-2.3]) (p < 0.01). This observation indicates that an elevated GGT level could be suggested as a subsidiary marker for MS and partially reflects dyslipidemia as a component of MS.
