In cases of abdominal trauma, elevated liver enzyme levels can indicate hepatic injury. To date, there are no documented reports of hepatic trauma without liver enzyme abnormalities. Herein, we present a case of hepatic subcapsular hematoma following a motor vehicle accident without abnormal findings in blood and biochemical tests over the course of time. The patient was a woman in her 20s who had collided with a passenger car while driving a light motor vehicle. She walked by herself to see a nearby after-hour doctor as an outpatient. Radiography was performed, and the patient was discharged on the same day. She was reexamined the next day and referred to our medical center due to possible hepatic injury. Her respiratory and circulatory dynamics were stable; however, she experienced mild tenderness in her right upper abdomen upon arrival. Echo-free space was observed in Morrison's and Douglas' pouches on abdominal ultrasound, and abdominal computed tomography showed a hepatic subcapsular hematoma (grade II according to the American Association for the Surgery of Trauma liver injury scale). However, blood and biochemical tests did not reveal any abnormalities. The hematoma reduced with conservative treatment after admission, and the patient was discharged on the 18th hospital day. This case indicates that hepatic injury cannot be ruled out based on serodiagnosis alone; thus, diagnostic imaging is required in cases of blunt abdominal trauma.

A 12-week exposure study was conducted to evaluate the growth performance and activities of some liver enzymes of African catfish (Clarias gariepinus) juveniles cultured in water hyacinth (Eichhornia crassipes) infested concrete and plastic culture media. 152 fish juveniles were introduced into two large concrete tanks (6.0 m × 5.0 m × 1.2 m) for the outdoor experiment. A tank was infested with E. crassipes plant at a density of 12.30 plants/m2, while the other tank, which served as the control, contained no water hyacinth plant. For the laboratory experiment, 50 fish juveniles were stocked in duplicate into five circular plastic tanks (labelled CT, T1, T2, T3, and T4) containing water hyacinth plants cultured at densities of 0, 5, 10, 20, and 40 plants/tank respectively. The on-growing fish were fed (2 mm) fish feed (45% crude protein) at 5% body weight twice daily. The result showed that fish juveniles grown in the water hyacinth-infested culture media (both indoor and outdoor) had significantly (p

Introduction and objectives: The purpose of this study was to confirm whether hepatitis B virus (HBV) infection and the levels of liver enzymes would increase the risk of prediabetes and diabetes mellitus (DM) in China. Materials and methods: A total of 10,741 individuals was enrolled in this prospective cohort study. Cox regression analysis was used to calculate the Hazard ratios (HRs) to evaluate the relationships between HBV infection and the risk of DM and prediabetes. Decision trees and dose response analysis were used to explore the effects of liver enzymes levels on DM and prediabetes. Results: In baseline population, HBV infection ratio was 5.31%. In non-adjustment model, the HR of DM in HBV infection group was 1.312 (95% CI, 0.529–3.254). In model adjusted for gender, age and liver cirrhosis, the HR of DM in HBV infection group were 1.188 (95% CI, 0.478–2.951). In model adjusted for gender, age, liver cirrhosis, smoking, drinking, the HR of DM was 1.178 (95% CI, 0.473–2.934). In model further adjusted for education, family income and occupation, the HR of DM was 1.230 (95% CI, 0.493–3.067). With the increases of levels of Alanine aminotransferase (ALT), Aspartate aminotransferase (AST) and Gamma-glutamyl transferase (GGT), the risk of prediabetes was gradually increasing (Pnon-linearity

Background: Metabolic syndrome (MetS) is a major health problem in the Saudi Arabian population. The aim of this study was to determine the status of antioxidant enzymes, liver enzymes, and intake of selected nutrients in subjects with MetS among Saudi adults in Taif city. Methods: In this case-control study, a total of 104 subjects (76 with MetS and 28 controls) were recruited. Demographic data was obtained from the participants. Evaluation of anthropometric variables, glucose, lipid profiles, antioxidant enzymes and liver profile were performed. Dietary intake was evaluated through FFQ. Results: A positive correlation was observed between protein intake and alanine transaminase (ALT) among subjects with MetS (R = 0.33; p

Objectives: Hepatic damage caused by oxidative stress is one of the problems associated with the emission of electromagnetic radiation (EMR). In this study, the effects of swimming exercise (SE) on oxidative stress and liver cell damage caused by EMR emission in rats were investigated., Methods: Thirty-two rats (8 weeks old) were randomly divided into four groups, including control (C), EMR, SE, and EMR + SE. During four weeks, the animals engaged in SE (30 min/session, 5session/week) and were also exposed to EMR (4 h/day, seven days/week) emission from a Wi-Fi 2.45GHZ router. The liver and blood samples were collected at 48 h after completing four weeks of SE to assess histopathological damage, oxidative stress, and liver enzymes., Key Findings: Tissue sections showed severe liver damage in the EMR group compared to the C group, while the SE attenuated the liver damage. In the EMR group, compared to the C, SE and EMR + SE groups, the activity of superoxide dismutase (SOD) and catalase (CAT) decreased significantly, and the concentration of malondialdehyde (MDA) and liver enzymes (AST, ALT, and ALP) increased significantly (P < 0.05). Swimming exercise in the SE and EMR + SE groups compared to EMR led to a significant increase in the activity of SOD and CAT and a significant decrease in the concentration of MDA and liver enzymes (P < 0.05)., Conclusion: The study findings showed that the SE is beneficial in attenuating the harmful effects of RF-EMR emitted from the Wi-Fi on the liver., Competing Interests: Declaration of competing interest The authors declare that there are no conflicts of interest., (Copyright © 2023 Elsevier Inc.

Background: Previous research reported inconsistent findings regarding the effects of conjugated linoleic acid (CLA) supplementation on liver enzymes. This systematic review and meta-analysis was conducted to summarize data from available randomized clinical trials (RCTs) on the effect of CLA supplementation on alanine aminotransferase (ALT), aspartate aminotransferase (AST) and malondialdehyde (MDA) in adults., Methods: Google Scholar, PubMed, Web of Science, Scopus, and the Cochrane databases were investigated to identify relevant articles up to July 2022. The weighted mean differences (WMD) and 95 % confidence intervals (CI) were calculated via a random-effects model to evaluate the effect size. Between studies, heterogeneity was evaluated by the Cochran's Q test and I 2 ., Results: 22 RCTs with 26 effect sizes were included. The effect size for ALT (IU/L), AST (IU/L), and MDA (µmol/L) were 19, 19 and 6 respectively. The pooled analysis demonstrated CLA decreases MDA (p = 0.003). However, ALT and AST levels did not change after CLA supplementation compared with control group., Conclusion: CLA supplementation may significantly reduce MDA levels as a marker of oxidative stress. However, supplementing with CLA failed to alter ALT and AST., Competing Interests: Conflict of interest The authors declared that there is no conflict of interest., (Published by Elsevier Ltd.)

Introduction: The aim of the study was to elucidate the predictive and prognostic value of serum gamma-glutamyltransferase (GGT) in patients with invasive bladder cancer (BC)., Patients and Methods: Preoperative serum GGT concentrations were assessed in 324 patients treated with RC for cM0 BC between 2002 and 2013. Laboratory values were obtained 1 to 3 days prior to RC. Uni- and multivariable analyses were carried out to evaluate clinicopathologic risk factors for survival. The median follow-up was 36 months (IQR: 10-55)., Results: Elevated preoperative GGT levels were diagnosed in 77 patients (23.8%). Elevated GGT was significantly associated with higher ECOG PS and tumor stage (both P = .001), lymph-node tumor involvement (P < .001), positive surgical margins (P = .018), lymphovascular invasion (P = .024), muscle-invasive disease at primary diagnosis (P = .033), increased tumor size (P = .035), hydronephrosis at RC (P = .049) and increased preoperative CRP, GPT and GOT levels (both P < .001). Patients with elevated GGT had decreased 3-year overall (49.2% vs. 69.6%; P = .005) and cancer-specific survival (71.1% vs. 80.9%; P = .042) compared with patients with normal levels. On multivariable analysis, advanced tumor stage (P = .032), lymph node positive disease (P = .030), positive soft tissue surgical margins (P = .014), hydronephrosis at RC (both P = .010), higher ECOG performance status and elevated GGT (P = .043) levels were independent predictors of all-cause mortality., Conclusion: Elevated preoperative serum GGT levels are associated with increased risk of locally advanced BC and mortality after RC. These data suggest that GGT levels may be useful for improved prognostication in invasive BC., (Copyright © 2022. Published by Elsevier Inc.)

Objective: To investigate the association between MYLIP rs3757354 and ABCA1 2230806 single nucleotide polymorphisms in women with preeclampsia in China., Study Design: The case-control study involved 205 patients with preeclampsia and 145 controls. All women with preeclampsia were divided into two groups: 78 patients with early-onset preeclampsia and 127 with late-onset preeclampsia., Main Outcome Measure: MYLIP rs3757354 and ABCA1 rs2230806 SNPs were analyzed through multiplex PCR for targeted next-generation sequencing technology. A secondary outcome was lipid profile changes and liver function in women with PE., Results: Maternal age (OR: 1.073, 95% CI = 1.006-1.145), BMI (OR: 1.118, 95% CI = 1.040-1.201), TG/HDL-C (OR: 1.536, 95% CI = 1.080-2.183), and TT genotype of SNP rs3757354 (OR: 3.238, 95% CI = 1.313-7.990) were associated with EOPE risk. Our study found that patients with TT genotype of ABCA1 rs2230806 had more severe hepatic dysfunction and higher HDL levels in the EOPE group compared with CC/CT genotype. There was no association between rs2230806 and the risk of PE., Conclusion: The polymorphisms of rs3757354 are associated with the risk of EOPE in Chinese pregnant women. The TT genotype in ABCA1 rs2230806 is a strong predictive risk for elevated aminotransferase levels in pregnant women with EOPE., (Copyright © 2020 International Society for the Study of Hypertension in Pregnancy.

Objective: Existing evidence on the possible effects of ginseng on liver function has not been fully established. Therefore, the present review was undertaken to evaluate the overall effects of ginseng supplementation on liver enzymes in adults., Methods: A systematic computerized literature search of PubMed, Scopus, Web of Science, Cochrane Library and Google scholar databases was conducted up to May 2019. All RCTs using ginseng supplements in adults were included in this systematic review and meta-analysis., Results: Overall, 14 randomized trials (with 20 arms) including 992 subjects were identified. Pooled analysis did not illustrate any significant changes in alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), alkaline phosphatase (ALP), and albumin (ALB) levels, however, it showed a minor significant increase in bilirubin (BIL) levels. Subgroup analysis by dosage and study population revealed significant increase of bilirubin after ginseng supplementation ≥3 g/day or in unhealthy individuals., Conclusion: Ginseng appears to have neither hepatoprotective nor hepatotoxic effects in conventional doses and duration. It is noteworthy that this seems applicable only for individuals with healthy liver function. Further largescale studies are warranted to confirm present findings., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2020 Elsevier Ltd.

Background: A proportion of twin-twin transfusion syndrome (TTTS) patients may have elevated liver enzymes (ELEzs) before fetoscopic laser therapy, but the incidence of ELEzs before laser therapy and the association with the perinatal outcomes after laser therapy remain unclear., Methods: From October 2008 to April 2015, 93 patients with TTTS who received fetoscopic laser therapy at our hospital were included in this study, and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were measured within 24 h before therapy. If ELEzs (AST > 34 U/L or ALT > 36 U/L) were observed before therapy, the AST and ALT levels were evaluated within 24 h after therapy. The pre-operative characteristics and post-therapy outcomes were compared between patients with and without ELEzs., Results: Among 93 TTTS patients before laser operation, 18 patients (were found with ELEzs (19.4%) before laser therapy. In 17 (94.4%) of the 18 cases, their liver enzymes values dropped after laser surgery. Maternal body mass index, age, gestational age of laser therapy, hemoglobin level before laser therapy and survival rates after laser therapy were not significantly different between TTTS with and without ELEzs. The maternal hemoglobin dropped significantly from 10.8 [1.6] g/dL before surgery to 9.6 [1.5] g/dL after laser therapy in TTTS with ELEzs (p < 0.001)., Conclusion: An elevated liver enzyme was not associated with poor perinatal outcomes in patients with TTTS after laser therapy. The authors suspected that the reduced liver enzymes values after laser therapy could partly arise from the hemo-dilution effect., (Copyright © 2019 Chang Gung University. Published by Elsevier B.V.

Background: Liver diseases have been bound to environmental factors, inclusive of air pollution. The exposure of workers to petrochemicals counts as a possible cause of Liver diseases, whereas results are inconsistent with the previous studies. In this study, a meta-analysis is conducted to assess the pooled risk., Methods and Finding: A systematic search was performed by related researchers. Correlations are analyzed among petroleum and liver cirrhosis mortality, fatty liver, alanine amino transferase (abbreviated as ALT), aspartate amino transferase (abbreviated as AST). Pooled risk ratios (RR) with 95% confidence interval (CI) and effect size(ES) with 95% confidence interval are calculated. Sensitivity analysis and publication bias are also tested. Data are analyzed from 5 studies involving 296 participants. Results are incorporated through adopting a random effects meta-analysis. Working in a petrochemical plant shall not increase the death risk posed by cirrhosis (RR = 0.44, 95% CI [0.36; 0.54]). Yet the incidence of fatty liver increases (RR = 1.22, 95% CI [1.21; 1.23]). Abnormal incidence of ALT and AST also increases., Conclusions: Occupational exposure plays an important role in causing ALT abnormalities and fatty liver among oil workers, but not a risk factor of cirrhosis, AST abnormalities and liver cancer., (Copyright © 2018 Elsevier Inc.

Women with polycystic ovary syndrome (PCOS) have a higher prevalence of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) than the general population. The link between NAFLD/NASH and PCOS is not just a coincidence. Indeed, both of these disorders comprise common risk factors, including central obesity, insulin resistance, chronic low-grade inflammation, and hyperandrogenemia. The characteristics of hyperandrogenemia in women with PCOS include elevated total and free testosterone levels and low sex hormone-binding globulin levels and are reported to be associated with NAFLD and elevated liver enzymes; however, not all elevated androgen levels in women with PCOS have the same adverse effects on the liver. With the exception of weight loss and encouraging exercise in obese women, few evidence-based effective treatments target NAFLD/NASH in women with PCOS. Selective antiandrogens and insulin sensitizers might be beneficial in treating NAFLD/NASH in women with PCOS, but further elucidation is needed., (Copyright © 2016. Published by Elsevier Ltd.)

Objective: Melissa officinalis is a perennial herb from the Lamiaceae family which has shown to have modulating effects on serum lipid profile. The aim of the current study is to explore the effects of M. officinalis supplementation on serum biochemical parameters of patients with borderline hyperlipidemia., Methods: 58 hyperlipidemic patients were allocated randomly to 2 groups: first group received capsules containing 1000mg M. officinalis leaf powder (MO group), and the second group received placebo capsules (P group) 3 times per day for 2 months. Fasting blood glucose (FBG), HDL, LDL, Triglyceride, Creatinine and liver function enzymes including AST and ALT were evaluated before and after study., Results: The mean of LDL in MO group significantly decreased compared with P group after the supplementation (P=0.02). Although the level of Cholesterol, FBG, HDL, Triglyceride, Creatinine and ALT did not show significant difference between two groups after 2 months (P≥0.05), the level of AST exhibited a significant difference between two groups (P=0.009)., Conclusions: Our findings demonstrated that M. officinalis supplementation as a rich source of antioxidants and bioactive compounds can be effective in remission of LDL and AST levels in patients with borderline hyperlipidemia., (Copyright © 2016 Elsevier Ltd.

Few epidemiologic studies describe longitudinal liver chemistry (LC) elevations in cancer patients. A population-based retrospective cohort was identified from 31 Phase 2-3 oncology trials (excluding targeted therapies) conducted from 1985 to 2005 to evaluate background rates of LC elevations in patients (n = 3998) with or without liver metastases. Patients with baseline liver metastases (29% of patients) presented with a 3% prevalence of alanine transaminase (ALT) ≥ 3x upper limits normal (ULN) and 0.2% prevalence of bilirubin ≥ 3xULN. During follow-up, the incidence (per 1000 person-months) of new onset ALT elevations ≥3xULN was 6.1 (95% CI: 4.5, 8.0) and 2.2 (95% CI: 0.9, 4.5) in patients without and with liver metastases, respectively. No new incident cases of ALT and bilirubin elevations suggestive of severe liver injury occurred among those with liver metastases; a single case occurred among those without metastasis. Regardless of the presence of liver metastases, LC elevations were rare in cancer patients during oncology trials, which may be due to enrollment criteria. Our study validates uniform thresholds for detection of LC elevations in oncology studies and serves as an empirical referent point for comparing liver enzyme abnormalities in oncology trials of novel targeted therapies. These data support uniform LC stopping criteria in oncology trials., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Objective: Intrahepatic cholestasis of pregnancy (ICP) is known to be associated with fetal complications. It recently was suggested to be associated possibly with preeclampsia (PET) as well. The objective of this study was to investigate that possibility., Study Design: The study group included 78 women (54 singleton and 24 twin pregnancies) who had been diagnosed with ICP based on clinical presentation, elevated liver enzymes, and elevated total bile acids (>10 μmol/L). Disease severity was based on total bile acids levels as being severe (>40 μmol/L), moderate (20-40 μmol/L), or mild (10-20 μmol/L). The course of disease was reviewed carefully in each case. The control groups were comprised of apparently healthy women with singleton (n = 200) and twin (n = 100) pregnancies that were drawn randomly from a computerized registry of all the deliveries in our institution during the study period., Results: The total incidence of PET was significantly higher for the patients with ICP who had singleton and twin pregnancies compared with the control groups (singletons: 7.4% vs 1.5%; P < .05; twins: 33.3% vs 6.2%; P < .05, respectively). The incidence of severe PET was also significantly higher in both singleton (11-fold) and twin (8-fold) pregnancies compared with control subjects. Severe ICP, but not mild ICP, was a major risk factor for PET among women with either singleton or twin pregnancies. The timing of the initial presentation of ICP had no effect on PET incidence rates. Preeclampsia occurred usually 2-4 weeks after the diagnosis of ICP, and proteinuria preceded elevated blood pressure in all cases. Moreover, the total bile acid levels among 33 women who were diagnosed as having PET, but not ICP, were within normal range., Conclusion: ICP increases the incidence of PET; severe disease was a major risk factor for preeclampsia. Therefore, we strongly suggest including routine evaluation for preeclampsia in the treatment of women with moderate and severe ICP., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Background & Aims: We used longitudinal data from the ANRS CO13 HEPAVIH cohort study of HIV-HCV co-infected individuals to investigate whether polyphenol rich food intake through coffee and/or daily chocolate consumption could play a role in reducing liver enzymes levels., Methods: Longitudinal data collection included self-administered questionnaires and medical data (aspartate aminotransferase (AST) and alanine aminotransferase (ALT) liver enzymes). Two analyses were performed to assess the association between coffee (≥3 cups a day) and daily chocolate intake and abnormal values of AST and ALT (AST or ALT >2.5 × upper normal limit (UNL)) (N=990) over time, after adjustment for known correlates. Logistic regression models based on generalized estimating equations were used to take into account the correlations between repeated measures and estimate adjusted odds ratio., Results: After adjustment, patients reporting elevated coffee consumption and daily chocolate intake were less likely to present abnormal ALT (OR=0.65; p=0.04 and OR=0.57; p=0.04, for coffee and chocolate respectively), while only patients reporting elevated coffee consumption were less likely to have abnormal AST values (p=0.05). Nevertheless, the combined indicator of coffee and chocolate intake was most significantly associated with approximately 40% reduced risk of abnormal liver enzymes (p=0.003 for AST; p=0.002 for ALT)., Conclusions: Elevated coffee consumption and daily chocolate intake appear to be associated with reduced levels of liver enzymes in HIV-HCV co-infected patients. Further experimental and observational research is needed to better understand the role that polyphenol intake or supplementation can play on liver disease and liver injury., (Copyright © 2013 European Association for the Study of the Liver.
