BackgroundCoronavirus disease 2019 (COVID-19) pandemic has become the most severe global health issue. Abnormal liver functions are frequently reported in these patients. However, liver function abnormality was often overlooked during COVID-19 treatment, and data regarding liver functions after cure of COVID-19 is limited. This study aimed to reveal the changes of liver function tests (LFTs) during hospitalization, and its clinical significance in patients with COVID-19.MethodsIn this retrospective, bi-center study, a total of 158 hospitalized patients diagnosed with COVID-19 in China were included from January 22nd, 2020 to February 20th, 2020. Clinical features, laboratory parameters including LFTs, and treatment data were collected and analyzed. LFTs included alanine transaminase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transferase, and total bilirubin. Patients were considered with abnormal LFTs when any value of these tests was higher than upper limit of normal.ResultsOf 158 patients with COVID-19, 67 (42.41%) patients had abnormal LFTs on admission and another 50 (31.65%) patients developed abnormal LFTs during hospitalization. The incidence of LFTs abnormality in severe COVID-19 cases was significantly higher than non-severe cases. All LFTs in COVID-19 patients were correlated with oxygenation index. There was no statistical difference in treatment between the patients with or without liver test abnormalities. By the time of discharge, there were still 64 (40.50%) patients with abnormal LFTs. Logistic regression analysis identified younger age, hypertension and low lymphocyte counts as independent risk factors for persistent abnormal LFTs during hospitalization.ConclusionLiver function tests abnormality was common in COVID-19 patients and was more prevalent in severe cases than in non-severe cases. A substantial percentage of patients still had abnormal LFTs by the time of discharge.

Background: Occupational lead poisoning is common in workers of some industries, but lead hepatotoxicity has rarely been reported. Several animal studies have revealed lead induced liver damage but clinical studies concerning the manifestations of lead induced liver toxicity in humans are scares. This study was designed to investigate the clinical manifestations and pathological parameters of hepatic dysfunction and its relationship with blood and urine lead concentrations in a car battery-manufacturing workers. Methods: This cross sectional study was carried out in Mashhad, Iran, during April-June 2011. One hundred and twelve workers underwent blood and urine sampling for determination of lead concentrations and liver function tests. Clinical signs and symptoms of possible lead hepatotoxicity were investigated. Results: Mean (±SD) age of the workers was 28.78 (±5.17) yr with a daytime work of 8.67 (±1.41) h and mean work duration of 3.89 (±2.40) yr. Mean blood lead concentration (BLC) and urine lead concentration (ULC) were 398.95 (±177.41) µg/l and 83.67(±50) μg/l, respectively. We found no correlation between the clinical findings and BLC or ULC. A weak correlation (R: 0.27, P=0.087) between serum alkaline phosphatase concentration and BLC was obtained. No significant relationship was found between other liver function tests and BLC or ULC. Conclusion: We found no specific clinical and laboratory abnormalities of liver in the workers of car battery manufacturer who had chronic lead toxicity. Further investigations with more specific laboratory tests such as LDH5 and gamma glutamyl transferase (GGT) as well as novel biomarkers of metal induced hepatotoxicity might be helpful in evaluating lead hepatotoxicity.

Herbicide 2,4-dichlorophenoxyacetic acid (2,4-D), a synthetic auxin which promotes uncontrolled plant growth is widely used. The aim of our study was to investigate, using an experimental model, the effect of herbicide 2,4-D on liver function tests, enzyme a amylase and glucose blood level. BALB/C mice were treated i.p. with the herbicide (30 mg/ kg 2,4-D) for four consecutive days. Twenty-four hours after the last injection, the treated and the control animals were weighed and sacrificed for biochemical analysis: haematocrit, glucose blood level, serum activities of enzymes alanine aminotransferase, aspartate aminotransferase, gamma glutamyl transferase, and a amylase, as well as liver reduced glutathione. Herbicide 2,4-D significantly decreased glucose blood level in mice. There were no changes in liver function tests or activity of enzyme a amylase. In this study on mice we confirmed the results obtained in the previous study, which showed a hypoglycemic effect of herbicide 2,4-D on agricultural workers. To elucidate the mechanism of this effect, a further research is needed.

ObjectivesLiver disease is a major cause of morbidity and mortality in sub-Saharan Africa, but its prevalence, distribution and aetiology have not been well characterised. We therefore set out to examine liver function tests (LFTs) and liver fibrosis scores in a rural African population.DesignWe undertook a cross-sectional survey of LFTs. We classified abnormal LFTs based on reference ranges set in America and in Africa. We derived fibrosis scores (aspartate aminotransferase (AST) to Platelet Ratio Index (APRI), fibrosis-4, gamma-glutamyl transferase (GGT) to platelet ratio (GPR), red cell distribution width to platelet ratio and S-index). We collected information about alcohol intake, and infection with HIV, hepatitis B virus (HBV) and hepatitis C virus (HCV).SettingWe studied a population cohort in South-Western Uganda.ParticipantsData were available for 8099 adults (median age 30 years; 56% female).ResultsThe prevalence of HBV, HCV and HIV infection was 3%, 0.2% and 8%, respectively. The prevalence of abnormal LFTs was higher based on the American reference range compared with the African reference range (eg, for AST 13% vs 3%, respectively). Elevated AST/ALT ratio was significantly associated with self-reported alcohol consumption (p<0.001), and the overall prevalence of AST/ALT ratio >2 was 11% (suggesting alcoholic hepatitis). The highest prevalence of fibrosis was predicted by the GPR score, with 24% of the population falling above the threshold for fibrosis. There was an association between the presence of HIV or HBV and raised GPR (p=0.005) and S-index (p<0.001). By multivariate analysis, elevated LFTs and fibrosis scores were most consistently associated with older age, male sex, being under-weight, HIV or HBV infection and alcohol consumption.ConclusionsFurther work is required to determine normal reference ranges for LFTs in this setting, to evaluate the specificity and sensitivity of fibrosis scores and to determine the aetiology of liver disease.

The effect of a regular oral diet supplying 167 kJ/kg per d (40 kcal/kg per d) on nutritional state, liver function and serum lipid profile was assessed in thirty severely malnourished alcoholic cirrhotic in-patients. Their diet was monitored by a trained dietitian and they were vigorously encouraged to eat all meals served. One month after their entry into the study, protein and energy intakes were significantly higher (P0·001) in keeping with an improvement of their nutritional status as evaluated by means of height-creatinine index, muscular mid-arm circumference, tricipital skinfold thickness (P0·01 for all) and fat mass (P0·001). Assessment of liver function tests showed that levels of aspartate amino-transferase (EC2.6.1.1), y-glutamyl transferase (EC2.3.2.2) and bilirubin decreased (P <0·05,P> 0·02 andP> 0·05 respectively) while prothrombin time values increased (P< 0·05). Similarly, serum albumin increased modestly while transthyretin did not change. Orosomucoid and C-reactive protein decreased (P< 0·001 andP< 0·01 respectively), indicating an improvement of the inflammatory state. Apolipoprotein Al and high-density-lipoprotein (HDL)-cholesterol correlated with several tests of liver function and improved significantly during the study period (P< 0·001 andP< 0·02 respectively). Moreover, changes in cholesterol and HDL-cholesterol correlated with those in transthyretin (P< 0·02 andP< 0·05 respectively). The changes in ApoAl and HDL-cholesterol were greater in patients whose fat mass increased significantly. Our findings show that adequate oral nutrition resulted in a better nutritional status in cirrhotics after 1 month of hospitalization. The serum lipid variables appeared to be more useful indicators of functional liver improvement than the classic liver function tests which rather indicate liver damage.

Background: Rheumatoid arthritis (RA) is associated with abnormal liver tests, and the medications used for RA are often hepatotoxic. Therefore, this study aimed to investigate an association between pro-inflammatory and anti-inflammatory cytokines and liver function tests in RA patients. Methods: In this descriptive cross-sectional study, 88 RA patients were included, 84 of them were women and 4 men, aged 21–81 years. Serum interleukin-10 (IL-10), interleukin-17 (IL-17), Osteopontin (OPN) were measured and liver function tests were conducted. Results: The frequency of RA was higher among adults aged >41 years (72 [81.8%]) than young adults aged ≤41 years (16 [18.2%]). RA was more common in women (84 [95.5%]) than in men (4 [4.5%]) – approximately 21:1-fold. Young adults had higher abnormal IL-10 than adult RA patients (OR = 3.72, p-value 0.044). Abnormal IL-17 (OR = 5.67, p-value 0.034) was found to be increased in young-adult RA patients. No association was observed between age and OPN and between the duration of disease and IL-10, IL-17, and OPN. Similarly, no association was noted between the types of treatment and IL-10, IL-17, and OPN, nor between IL-10, IL-17, OPN and liver parameters (AST, ALT, ALP, ALB, TP, and GGT). Conclusion: Pro-inflammatory and anti-inflammatory cytokines are not associated with abnormal liver functions, as has been demonstrated in RA patients.

AbstractThe knowledge of the existing levels and the interrelationships between various blood and milk parameters is very useful for the analysis and monitoring of homeostasis high-yielding dairy cows. The aim of the study was to evaluate these values and correlations for selected blood markers of liver function aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transferase (GGT), bilirubin, albumin, glucose, cholesterol) and selected milk parameters: somatic cell count (SCC), colony-forming units (CFU), fat, protein, lactose, dry matter (DM), fat-free dry matter (FDM), and milk production in cows during late lactation period. At the same time blood and milk samples were collected from 11 clinically healthy milking cows in later lactation period. The 11 selected cows were examined once a day for 3 days resulting in 33 sets of blood and milk samples for laboratory and statistical analysis. Significant positive correlations were observed between: ALT and albumin, ALT and cholesterol, GGT and glucose, albumin and cholesterol, CFU and fat, CFU and DM, SCC and protein, fat and DM, protein and FDM, lactose and FDM, GPT and FDM, albumin and protein, albumin and FDM, glucose and fat, as well as significant negative correlations between: AST and ALT, AST and GGT, AST and albumin, CFU and lactose, fat and lactose, fat and FDM, lactose and DM, DM and FDM, AST and SCC, AST and protein, AST and FDM, ALT and fat, ALT and DM, glucose and DM, cholesterol and CFU. The results obtained may be important for detecting of different biochemical pathways and helpful in estimating, predicting or determining trends, the direction of changes in liver functions and assessing the risk of alert levels for liver blood markers, when only daily results of milk parameters are available.

The present study was conducted in Khartoum state (Sudan) as a cross-sectional study in 200 participants (100 smokers and 100 non-smokers), to investigate the effects of Cigarettes Smoking on Liver functions of Sudanese smokers. The smokers were categorized into either current smokers (70 participants) or past smokers (30 Participants). Parameters were analyzed by using spectrophotometer. From the results, the levels of liver function tests (TB, Albumin and globulin) were significantly higher in non-smokers (6.0, 3.6 and 2.43 g/dl) as compared to current smokers (4.4, 2.4 and 1.98 g/dl) and past smokers (4.7, 2.7 and 1.93 g/dl). Meanwhile, ALT was significantly increased in current and past smokers as compared to non-smokers, where as AST was significantly higher in current smokers as compared to non-smokers, while there was no significant difference between current and past smokers as well as between past and non-smokers for this parameter. In addition, heavy and long duration of smoking were both associated with low total protein, albumin and AST levels .Also liver function tests were not significantly differing in current smoker's non-diabetics and non-smokers diabetics except total protein. From the results when, liver enzymes raised that may lead to increase proteins metabolism and increase blood glucose. These signs may place cigarettes smoking one of the top causes of hepatitis, pancreatitis, insulin resistance and finally diabetes mellitus type II. On the other hand, smoking cessation in diabetics lead to decrease the risk of hepatitis, Also regular physical activity and using medication regularly in diabetics lead to the same actions above; in addition diabetes complications were decreased.
