Glutamyl Transferase

Lead exposure and a marker of oxidative stress (gamma-glutamyl transferase—GGT), and their effects on life course variables (age, country of birth, education levels, gender, ethnicity, income, and occupation) were explored in this cross-sectional study of United States (U.S.) adults’ ≥ 20 years of age via the National Health and Nutrition Examination Survey (NHANES) 2007–2010 datasets. Country of birth, education levels, gender, ethnicity, income, and occupation showed significant differences depending on the degree of lead exposure, with higher levels of exposure resulting in worse outcomes. Age and GGT were significantly associated with lead exposure. More must be done to mitigate sources of lead exposure, to prevent it from altering the life course of at-risk populations.

In this cross-sectional study, lead exposure among those with a history in military environments was examined. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) are clinical markers of blood pressure, while gamma-glutamyl transferase (GGT) is a marker of oxidative stress. These markers and their effects on those exposed to military environments were explored using National Health and Nutrition Examination Survey (NHANES) data from 2009 to 2016. Mean SBP and GGT were significantly elevated in those exposed to military environments, with a moderately significant association existing between blood lead levels (BLLs) and SBP. More attention must be given to lead exposure in military environments to mitigate the risk of exposure.

Aim: The present study was undertaken with the aim to evaluate serum Gamma Glutamyl Transferase (GGT) levels in patients of acute coronary syndrome. Methodology: This cross-sectional study was conducted on 50 cases with acute coronary syndrome (Group A) and 50 healthy control subjects (Group B) meeting inclusion and exclusion criteria. Results: There is signicant rise in serum GGT levels in patients presenting with ACS in Group A as compared to Group B. Conclusion: Higher levels of GGT in ACS patients with risk factors such as hypertension, dyslipidemia and smoking may serve as biomarker to predict the occurrence of ACS.

Cat Gene

Lead has been linked to the development of hypertension via oxidative stress. Catalase plays an important role in the disposal of hydrogen peroxide in erythrocyte and its activity was determined by CAT gene. The aims of this study were to investigate (1) the association between blood levels of antioxidant markers such as catalase, superoxide dismutase, glutathione, glutathione peroxidase, oxidative stress-marker (malondialdehyde), and blood lead level and (2) the influence of genetic polymorphism of CAT gene (rs769217) on change in blood pressure in general population of EGAT study project. This is a cross-sectional study of 332 normotensive, 432 prehypertensive, and 222 hypertensive male subjects. Hypertensive subjects had significantly higher blood lead level (5.28 μg/dL) compared to normotensive (4.41 μg/dL) and prehypertensive (4.55 μg/dL) subjects (P<0.05). These significant findings are also found in MDA levels. Moreover, individuals with TT genotype in hypertensive group had significantly higher blood lead and MDA levels (6.06 μg/dL and 9.67 μmol/L) than those with CC genotype (5.32 μg/dL and 8.31 μmol/L,P<0.05). Our findings suggested that decreased blood catalase activity in this polymorphism together with low level lead exposure induced lipid peroxidation may be responsible for hypertension.

The medical bibliography is deficient in research involving structural and laboratory abnormalities of the liver in asymptomatic and oligosymptomatic male alcoholics. The present study describes the alterations in tests that evaluate liver aggression, lesion and dysfunction, also correlating these with the changes in the consistency and sensitivity of the liver in aged and non-aged alcoholics. Cross-sectional study involving 100 alcoholic men, 50 aged and 50 non-aged. Of the aged and non-aged, respectively, the liver was palpable in 68% and 80%, the spleen was percutable in 72% and 74% and palpable in 12% and 22%, non-painful soft hepatomegaly was observed in 14% and 8%, painful hepatomegaly in 0% and 2%, firm hepatomegaly (painful and non-painful) in 54% and 70%, hepatomegaly and splenomegaly (percutable and palpable spleen) in 84% and 84%, and portal hypertension in 10 % and 14%. Elevated levels of aspartate aminotransferase were observed in 66% and 84%, alanine aminotransferase in 24% and 60%, gamma glutamyl transferase in 46% and 82% and alkaline phosphatase in 0% and 16% of the aged and non-aged, respectively. Elevation of aspartate aminotransferase greater than twice the reference value and the ratio aspartate aminotransferase to alanine aminotransferase greater than 2 were observed in 18% and 42% and 18% and 10% of the aged and non-aged, respectively. Hypoalbuminemia and hyperbilirubinemia were observed in 70% and 24% of the aged and 40% and 44% of the non-aged, respectively. The clinical and laboratory alterations observed are compatible with acute liver disease in 18% and 42%; chronic liver disease in 54% and 70%; portal hypertension in 10% and 14% of aged and non-aged patients, respectively.

Alcoholic Fatty Liver Disease

Background: Non-alcoholic fatty liver disease (NAFLD) is a condition defined by excessive fat accumulation in the form of triglycerides (steatosis) in the liver. In recent years, an association between elevated serum uric acid concentrations and NAFLD has been reported. The aim of the study was to perform cross-sectional study to determine the association between serum uric acid levels and the levels of serum alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT), in NAFLD patients.Methods: In this hospital-based cross-sectional study, 300 patients with diagnosed NAFLD were included during the one-year period from July 2015 to June 2016.Results: Elevation of alanine aminotransferase levels was seen in a total of 93 cases (31%) and elevation of GGT levels in NAFLD patients was seen in 112 patients out of a total of 300 (37.33%). Hyperuricemia was observed in 99 cases out of a total of 300 cases of NAFLD (33%). A significant association was observed between the two parameters.Conclusions: The prevalence rate of NAFLD was significantly higher in subjects with hyperuricemia than that in those without hyperuricemia (78.19% versus 40.83 %) (p<0.001), and the prevalence rate increased with progressively higher serum uric acid levels (p<0.001). The relationship between rising uric acid levels with rising ALT and GGT levels in these patients was also found to be statistically significant.

<p class="abstract"><strong>Background:</strong> Hypertension, a chronic medical condition of elevated blood pressure in the arteries. It is an emerging problem worldwide and one of the identifiable cause of kidney disease. Gamma glutamyl transferase (GGT) plays essential role in the metabolism of glutathione which is reported as major antioxidant. More recently increased GGT is associated with pathogenesis of hypertension. This study was aimed to determine activity of gamma glutamyl transferase in hypertensive patients.</p><p class="abstract"><strong>Methods:</strong> All together 150 participants were recruited from Department of Medicine, Star Hospital for this hospital based cross-sectional study. Among which 50 were normotensive, 50 were pre-hypertensive and 50 were hypertensive. Blood sample were collected and analyzed in autoanalyser by enzymatic method.  </p><p class="abstract"><strong>Results:</strong> Mean serum gamma glutamyl transferase activity is significantly different among normotensive, prehypertensive and hypertensive groups (i.e., 10.3 IU/l, 26.8IU/l and 37.2 IU/l respectively). Serum gamma glutamyl transferase activity is significantly higher in prehypertensive patients than normotensive group (p=0.001). Similarly GGT activity is significantly increased in hypertensive patients than prehypertensive patients (p=0.001).</p><p class="abstract"><strong>Conclusions:</strong> Serum gamma glutamyl transferase activity is raised in prehypertensive and hypertensive participants as compared to normotensive. Thus Serum gamma glutamyl transferase level can have potential role on management of hypertension.</p>
