Abstract Background: The mechanisms underlying liver disease in patients with COVID-19 are not entirely known.Aim: To investigate, by means of novel statistical techniques, the changes over time in the relationship between inflammation markers and liver damage markers in relation to survival in COVID-19.Methods: The study included 221 consecutive patients admitted to the hospital during the first COVID-19 wave in Spain. Generalized additive mixed models were used to investigate the influence of time and inflammation markers on liver damage markers in relation to survival. Joint modeling regression was used to evaluate the temporal correlations between inflammation markers (serum C-reactive protein [CRP], interleukin-6, plasma D-dimer, and blood lymphocyte count) and liver damage markers, after adjusting for age, sex, and therapy.Results: The patients who died showed a significant elevation in serum aspartate transaminase (AST) and alkaline phosphatase levels over time. Conversely, a decrease in serum AST levels was observed in the survivors, who showed a negative correlation between inflammation markers and liver damage markers (CRP with serum AST, alanine transaminase [ALT], and gamma-glutamyl transferase [GGT]; and D-dimer with AST and ALT) after a week of hospitalization. Conversely, most correlations were positive in the patients who died, except lymphocyte count, which was negatively correlated with AST, GGT, and alkaline phosphatase. These correlations were attenuated with age. Conclusion: The patients who died during COVID-19 infection displayed a significant elevation of liver damage markers, which is correlated with inflammation markers over time. These results are consistent with the role of systemic inflammation in liver damage during COVID-19.

 Objective: The current study was designed to estimate the potential protective role of the aqueous extract of rosemary (AER) (Rosmarinus officinalis) against trichloroacetic acid (TCA)-created hepatotoxicity in male albino rats.Methods: Forty male albino rats were separated into four groups of ten: Group I served as control; Group II was given AER (200 mg/kg/day) by gavage; Group III received TCA at the dose 50 mg/kg/day, and Group V was treated with AER (200 mg/kg/day) and received TCA (50 mg/kg/day). The experiment was carried out for 2 months.Results: The toxicity of TCA for rats was revealed by an elevation in liver marker enzymes activities (gamma-glutamyl transferase [GGT], alkaline phosphatase [ALP], aspartate transaminase [AST], alanine aminotransferase [ALT]) and conjugated bilirubin (CB) level, and a decrease in albumin and total protein (TP) levels. The TCA administration also caused a significant increase in the activities of catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD), and also malondialdehyde (MDA) level in liver tissues. These biochemical effects were accompanied by histological indicators of liver damage. Treatment with ARE recovered the liver damage instigated by TCA, as showed by perfection of liver enzyme markers (GGT, ALT, AST, ALP), CB, TP and albumin; as well as antioxidant parameters (CAT, SOD, GPx) and lipid peroxidation (MDA) and amelioration of histopathology changes in the liver tissues.Conclusion: It could be concluded that AER supplementation for 2 months in TCA-induced toxicity in rats benefited hepatic antioxidant status and improved liver injury and damage in male albino rats exposed to TCA.

Background: Patients with liver disease associated with alpha-1 antitrypsin deficiency (AATD) are homozygous for the Z mutation, leading to chronic liver damage. Objective: To assess the serum levels of glutamate-oxaloacetate transaminase (GOT), glutamate-pyruvate transaminase (GPT), and gamma-glutamyl transpeptidase (GGT) in patients with different genotypes for the alpha-1 antitrypsin (AAT) gene. Methods: Patients (n = 1494) underwent genotyping of the SERPINA1 gene, together with a determination of AAT and GOT and GPT and GGT transaminase levels. Patients with a deficient allele (n = 476) and with a normal genotype were compared. Results: A statistically significant association was found between deficient genotypes and GOT (p < 0.0003), GPT (p < 0.002), and GGT (p < 0.006). Comparing GOT levels in patients with PI*Z deficient variant versus those with normal genotype, an odds ratio (OR) of 2.72 (CI: 1.5–4.87) (p < 0.0005) was obtained. This finding was replicated with the PI*Z allele and the GPT values (OR = 2.31; CI: 1.45–3.67; p < 0.0003). In addition, a statistically significant association was found between liver enzymes and AAT values. Conclusion: The PI*Z allele seemed to be a risk factor for the development of liver damage. AAT deficient genotypes were associated with GOT, GPT, and GGT altered values. Low AAT levels were associated with high GPT and GGT levels.

Abstract Continuous monitoring of heat denaturation of a mixture of alkaline phosphatase isoenzymes at 60 degrees C and pH 7.5 permits the simultaneous direct identification and quantitation of three isoenzymes: the placental isoenzyme, the L-phenylalanine-sensitive intestinal isoenzyme, and the liver isoenzyme (hepatocytic). The isoenzyme that is principally of bone origin cannot be identified as such without the help of other diagnostic aids and the patient's medical history. All human tissues contain alkaline phosphatase, many organs more than one of the isoenzymes. Liver alkaline phosphatase, which constitutes 40-50% of normal serum alkaline phosphatase activity, was measured in the serum of persons with various liver diseases. Its activity exceeded normal in all types of liver disease; in 80% of cases this increase was accompanied by increased gamma-glutamyl-transferase activity, but the quantitative correlationship (r = 0.54) was not as good as expected if both enzymes come from the same source and are indices of liver dieases. Liver alkaline phosphatase activity increases in the blood early in liver disease, before most liver tests show abnormalities. The other major isoenzyme of normal serum probably represents a mixture of isoenzymes from bone and reticulo-endothelial and vascular tissues, which all contain the same "very heat-labile" alkaline phosphatase. Cord blood and children's sera contain mostly this very heat-labile isoenzyme.

BACKGROUND: The choledocolithiasis has an incidence of 8-20% in patients with cholecystolithiasis. The preoperative diagnosis guides the interventional treatment on the bile duct AIM: To evaluate the sensitivity and specificity of the laboratory markers and imaging studies for choledocholithiasis preoperatively. METHODS: The study comprised 254 patients divided into two groups: the control group (207 patients), patients without choledocholithiasis intraoperatively and cases group (47 patients), that enrolled the patients with choledocholithiasis intra-operatively. Were evaluated the laboratory markers, image exams and intra-operative diagnostic aspects. RESULTS: The sample was homogeneous for age and gender. It was observed that 47% of the cases the patients did not show comorbidities. Hospitalization showes in cases group acute pancreatitis in12.8%, jaundice in 30%, fever in 30% and pain in the right hypochondrium in 95%. By comparing them, was observed that fever and jaundice were the signs and symptoms with statistical significance. Patients with choledocholithiasis had transaminases, alkaline phosphatase, gamma-glutamyl transferase and higher bilirubin with statistical significance (p<0.001). In regard to imaging studies, ultrasound was fairly accurate for cholelithiasis and choledocholithiasis (p<0.001). CONCLUSION: Changes in canalicular and transaminase enzymes are suggestive for preoperative choledocholithiasis; GGT showed better sensitivity and alkaline phosphatase greater specificity; ultrasonography and nuclear magnetic resonance cholangiopancreatography showed high specificity.

BACKGROUND Alcoholism remains to be the major cause of morbidity and mortality throughout the world. Consuming alcohol is the potent etiological factor for the development of alcoholic liver diseases (ALD), ranging from fatty liver to hepatocellular carcinoma with varying rates of development in both genders depending on the quality, quantity, and duration of the drink. Zinc deficiency has been documented with the progression of alcoholic liver disease. It is also a well-known fact that zinc is a co-factor for enzyme alkaline phosphatase. This study aims to assess the zinc status and alkaline phosphatase activity in patients with various stages of alcoholic liver disease, correlate zinc with alkaline phosphatase activity, albumin, gamma glutamyl transferase activity, MELD score and duration of alcohol intake and analysing the need for evaluating zinc in these patients. METHODS This comparative observational study involves group I healthy controls and group II patients diagnosed to have ethanol related decompensated liver disease with or without portal hypertension for more than three years from the Department of Medical Gastroenterology, Government Medical College Hospital. 5 ml of venous blood in fasting state was collected from both groups and assayed for serum zinc, and serum alkaline phosphatase activity. The data was statistically analysed. RESULTS The study results demonstrate that higher percentage of patients with alcoholic liver disease have low serum zinc levels than healthy controls. Zinc when compared with variables like serum albumin, duration of alcohol intake, MELD score, serum gamma glutamyl transferase and alkaline phosphatase in the case and control groups were found to be statistically significant. CONCLUSIONS There is decrease in serum zinc level and increased alkaline phosphatase activity in patients with alcoholic liver disease. The statistically significant data is a strong rationale for evaluating the zinc status and thereby supplementing zinc to patients with alcoholic liver disease.

Introduction: Diagnostic enzymology plays a useful role in evaluation of various hepatobiliary diseases and numerous enzymes have been compared in different disorders. Among these, significance of Gamma Glutamyl Transferase and 5’ Nucleotidase over Alkaline Phosphatase has been stressed repeatedly, but mainly in the icteric obstructive biliary disease patients. In this study, these three enzymes were compared not only in the icteric but also the an-icteric biliary disease patients, particularly to look for elevation and significance of these enzymes in the latter group.Methods: The study was conducted on 50 biliary disease patients, who were further divided into an-icteric (32 patients) and icteric (18 patients) subgroups depending on their bilirubin levels. 50 subjects matched for age and sex with the study group were enrolled for the control group. Gamma Glutamyl Transferase, 5’Nucleotidase, Alkaline Phosphatase and bilirubin levels were evaluated in all the patients as well as the control subjects. Results: All three enzymes showed a significant rise in the icteric subgroup (p value < 0.001). However, in the an-icteric subgroup, only Gamma Glutamyl Transferase and 5’Nucleotidase showed a significant rise. The rise was more for Gamma Glutamyl Transferse (1.60 times normal, p < 0.001) as compared to 5’Nucleotidase (1.39 times normal, p < 0.01). Conclusion: Gamma Glutamyl Transferase and 5’Nucleotidase are useful for evaluation of not only obstructive biliary disease patients but also for the patients with biliary disease who are an-icteric, and out of these two, the former is a more valuable diagnostic indicator in such diseases

We describe a case of two-year-old boy presenting with debilitating pruritus, patchy alopecia and jaundice since the age of 6 months. On evaluation he had intrahepatic cholestasis with persistently raised serum alkaline phosphatase, normal Gamma glutamyl transferase and raised serum bile acid levels. His liver biopsy showed bland cholestasis and electron microscopy showed granular bile suggestive of progressive familial intrahepatic cholestasis type I. Medical therapy with ursodeoxycholic acid, cholestyramine, rifampicin with nutritional modification was successful in alleviating the symptoms and correcting the nutritional status. To our knowledge this is only the sixth case of progressive familial intrahepatic cholestasis type I reported from India. Herein we discuss the diagnostic and therapeutic hurdles that one encounters in managing progressive familial intrahepatic cholestasis and also review the literature regarding this rare disorder.
