AMELIORATIVE EFFECT OF FERMENTED GOAT’S MILK COMBINED WITH DESERT TRUFFLE AND BAOBAB AQUEOUS EXTRACT IN CCL4 INDUCED LIVER LESION IN RATS

The aim of the present work was to investigate the synergistic hepatoprotective effect of fermented goat milk (FGM) combined with aqueous extracts of baobab (Adansonia digitata L.) (BE) and desert truffle (Terfezia claveryi) (DTE). Chemical analysis indicated that BE is rich in ascorbic acid (67.3 mg/100 g dry weight). Both extracts reduced the stable free radical DPPH (96.4 and for BE versus 70.2 % for BE and DTE, respectively). For examining the hepatoprotective effect of these treatments in vivo, thirty-six rats were randomly divided into six groups (n=6 per group). Group 1 served as the normal control (NC). Hepatotoxicity was induced in rats of the other five groups using CCl4. Group 2 served as the positive control (PC), while the remaining 4 groups received orally FGM, DTE, BE and their mixture (1:1:1) for 28 days. Hepatotoxicity was characterized by high liver weight as well as an elevation in serum levels of liver enzymes in the PC group. All treatments restored weight of liver to that of the NC group (P>0.05). Highest positive effect was recorded for DTE which lowered liver weight by 33.9% compared with PC group (P<0.05). Concentrations of liver enzymes were significantly reduced in all treatment groups compared to PC group. Moreover, the protective effect was further confirmed by histopathological as a considerable reduction in necrosis and fatty changes were noticed. In sum, FGM, Desert Truffle and Baobab could be potentially used as functional food to protect against liver lesion.

Protective Effect of Hydroalcoholic Extract of Clove on Thioacetamide-Induced Hepatotoxicity Animal Model: Effects Hydroalcoholic Extract of Clove Against Hepatotoxicity.

The drug-induced liver injury (DILI) has a wide range of clinical presentations, from asymptomatic liver enzyme elevations to cirrhosis. Herbal dietary supplements may be beneficial to reduce the risk of hepatotoxicity. This study aimed to evaluate the effects of different doses of clove extracts on humoral factors in rats with hepatotoxicity induced by thioacetamide. In this experimental study, rats were divided into nine groups (10 rats per each). The Control group received no treatment. The Sham group was treated with oral administration of distilled water (0.5 ml) for 21 days. The positive control group received thioacetamide (50 mg/kg for three days) intraperitoneally. The clove group was divided into three subgroups and given daily oral administrations of 50, 150, and 300 mg/kg of clove hydroalcoholic extracts (for 21 days). Rats in the experimental group were divided into three subgroups and subjected to 50 mg/kg thioacetamide injection after receiving hydroalcoholic extracts of clove (50, 150, and 300 mg/kg, respectively) for 21 days in the last three days. All rats were sacrificed after 48 hours to measure liver function parameters (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total plasma protein, and albumin). The rats that received thioacetamide showed liver damage by increased serum liver biomarkers and decreased levels of total plasma protein and albumin compared to the control group. The different doses of clove extract resulted in a significant improvement of liver damage by reduced serum liver enzymes levels and increased total plasma protein and albumin. Oral administration of the different doses of the clove extract (50, 150, and 300 mg/kg) for 21 consecutive days could significantly improve the changes associated with serum biomarkers of hepatotoxicity.

The associations between modifiable risk factors and nonalcoholic fatty liver disease: A comprehensive Mendelian randomization study.

Early identification of modifiable risk factors is essential for the prevention of nonalcoholic fatty liver disease (NAFLD). We aimed to systematically explore the relationships between genetically predicted modifiable risk factors and NAFLD. We applied univariable and multivariable Mendelian randomization analyses to explore the relationships between 35 modifiable risk factors and NAFLD. We also evaluated the combined results in three independent large genome-wide association studies. Genetically predicted alcohol frequency, elevated serum levels of liver enzymes, triglycerides, C-reactive protein, and obesity traits, including body mass index, waist circumference, and body fat mass, were associated with increased risks of NAFLD (all with p < 0.05). Poor physical condition had a suggestive increased risk for NAFLD (odds ratio [OR]=2.63, p =0.042). Genetically instrumented type 2 diabetes (T2DM), hypothyroidism, and hypertension all increased the risk for NAFLD, and the ORs (95% confidence interval) were 1.508 (1.20-1.90), 13.08 (1.53-111.65), and 3.11 (1.33-7.31) for a 1-U increase in log-transformed odds, respectively. The positive associations of T2DM and hypertension with NAFLD remained significant in multivariable analyses. The combined results from the discovery and two replication datasets further confirmed that alcohol frequency, elevated serum liver enzymes, poor physical condition, obesity traits, T2DM, and hypertension significantly increase the risk of NAFLD, whereas higher education and high-density lipoprotein cholesterol (HDL-cholesterol) could lower NAFLD risk. Genetically predicted alcohol frequency, elevated serum liver enzymes, poor physical condition, obesity traits, T2DM, and hypertension were associated with an increased risk of NAFLD, whereas higher education and HDL-cholesterol were associated with a decreased risk of NAFLD.

Melatonin attenuates thioacetamide-induced liver fibrosis in male rats through modulation of interleukin-6, interleukin-4, apoptosis and urokinase plasminogen activator receptor-associated protein/Endo180.

Liver fibrosis is a chronic progressive disease, its resolution still unclear, and the current study explored the role of melatonin in modulation of interleukin-6 (IL-6), interleukin-4 (IL-4), transforming growth factor beta1 (TGF-β1) and urokinase plasminogen activator receptor-associated protein/Endo180 (uPARAP/Endo180) pathway in thioacetamide (TAA)-induced hepatotoxicity. Thirty two adult Sprague-Dawley rats were divided into four groups: vehicle control group, TAA-induced liver fibrosis group that was left untreated, melatonin administration before and along with TAA and melatonin along with TAA group. TTA-induced massive liver necrosis, fibrosis around portal tract and increases serum levels of liver enzymes and total bilirubin when compared with control vehicle group. While both melatonin pretreatment and treatment retained liver parenchyma and liver enzymes quite similar to control group and reduced TAA-induced liver injury. Notably, melatonin pretreatment and treatment increased collagen degradation in TAA liver injury by19, 31.7-fold respectively evidence by collagen percentage area. Melatonin also decreased the amount of thiobarbituric acid reactive compounds and retained the reduced glutathione and superoxide dismutase to basal level quite similar to control group. Additionally, melatonin significantly (P value ≤0.05) decreased the levels of TGF-β1, epidermal growth factor (EGF), hydroxyproline, tissues IL-6, caspase-3, and receptor interacting serine/threonine kinase1 (RIPK1), fibrillin-1, and - smooth muscle actin in the liver tissues while significantly (P value ≤0.05) increasing the levels of IL-4 and uPARAP/Endo180. Due to its anti-inflammatory, anti-apoptotic, and antioxidant capabilities as well as its ability to decrease hepatic stellate cell activation and fibrogenesis, these data imply that melatonin has a powerful anti-fibrotic effect.

Effects of Avena sativa and Glycyrrhiza glabra Leaves Extracts on Immune Responses in Serum Cytokine and Liver Enzyme Levels in NIH Mice.

In addition to their high quantities of active chemicals, medicinal plants are well-known for their pharmacological qualities, which include immunological modulation. T Consequently, this study aimed to examine the effects of Avena sativa and Glycyrrhiza glabra leaf extracts on immunological responses as measured by blood cytokine and liver enzyme levels. The phytochemical analysis of Avena sativa crude leaf extracts revealed the presence of alkaloids,flavonoids, tannins, phenolic compounds, and saponins but the absence of resins and violet oils. On the other hand, violet oils, flavonoids, tannins, saponins, and glycosides were detected in significant concentration in Glycyrrhiza glabra ethanolic extract, although resins and phenolic compounds were not present. Fifty male NIH mice were randomly divided into five groups: Except for the control group, all animals were given subcutaneously and orally with extracts (50 mg/kg) for 14 days prior to LPS-induced (1 mg/kg body weight) liver injury. LPS-induced liver damage was induced on day 15, and mice were starved.Group 1 was injected subcutaneously with normal saline as a control. Group 2 received an injection of 100 l of crude oat extract subcutaneously. Group 3 was administered 100 l (50 mg/kg) of crude Oat extract orally. Group 4: administered 100 l (50 mg/kg) of crude Licorice extract subcutaneously. Group 5 ingested 100 l (50 mg/kg) of crude Licorice extract orally. IL-4 levels were significantly elevated (P< 0.05) in the subcutaneously and orally treated groups compared to the control group (12.3 0.23 pg/ml). IL-6 was significantly elevated (P<0.05) in mice given subcutaneously or orally with Avena sativa or Glycyrrhiza glabra extracts compared to mice treated subcutaneously or orally with a control substance (44 0.57 pg/ml). The concentration of TNF- was significantly elevated (P<0.05) in subcutaneous and oral treated groups (283.6 1.7 and 280.6 12.2; 233.9 0.6 and 241.2 2.8) compared with the control group (130 0.42) pg/ml. When mice were exposed to LPS-containing extracts, both GOT, and GPT levels fell relative to the control group.

Mucinous cystic neoplasm of the liver with polypoid nodule prolapsing into the bile duct: a case report and review of literature

BackgroundMucinous cystic neoplasm of the liver (MCN-L) is a rare cystic tumor as defined by the 2010 World Health Organization classification. MCN-L usually does not communicate with or grow into the bile duct. Herein, we present a rare case of MCN-L with a polypoid nodule protruding into the bile duct.Case presentationA 69-year-old woman was referred to our hospital for elevated serum liver enzyme levels and obstructive jaundice. The patient also complained of abdominal pain in the right hypochondriac region. Abdominal ultrasonography showed a cystic lesion in segment 4 (S4) of the liver. Computed tomography revealed a 4-cm multilocular cystic lesion with a thick wall and multiple septal formations, showing a cyst-in-cyst appearance in S4. Endoscopic retrograde cholangiography showed a contrast defect between the left hepatic duct and the common bile duct, which was suspected to be a nodular lesion in the bile duct. Bile cytology and biopsy of the nodular lesion showed no malignant findings. Based on these findings, the differential diagnosis in this patient included intraductal papillary neoplasm of the bile duct and MCN-L, which had malignant potential. The patient underwent left hemihepatectomy, including caudate lobe excision with bile duct resection and right hepatocholangiojejunostomy. Macroscopic findings showed a 40 × 29 mm multilocular cystic lesion with a polypoid nodule that protruded into the left intrahepatic bile duct. As an ovarian-like stroma was observed in both cystic and polypoid lesions microscopically, the histopathological diagnosis was MCN-L. The postoperative course was uneventful, and the patient was discharged 24 days after surgery. The patient is currently alive without recurrence 22 months after the surgery.ConclusionAlthough MCN-L rarely communicates with the bile duct, it is necessary to consider that MCN-L could grow into the bile duct, occasionally causing obstructive jaundice.

Estimation of serum iron, serum lipids and serum liver enzymes in celiac disease patients of Saudi Arabia

To evaluate the serum biochemical levels in celiac disease (CD) patients. It was a cross-sectional study carried out on 70 subjects, including 40 patients with CD and 30 healthy controls. This study was conducted at Jouf University from November, 2020 to October, 2021. The collected blood specimens were used to perform serum iron, serum lipids, liver enzymes, and human tissue transglutaminase IgA antibodies (anti-HTTG). The hematological parameters including hematocrit and MCV were determined to establish the diagnosis of iron deficiency. Serum iron was significantly lower in patients as compared to the controls. Serum iron, serum HDL, blood hematocrit and MCV were significantly lower in patients than in controls (p = 0.000). Serum levels of liver enzymes (ALT and AST) and serum human tissue transglutaminase antibodies (anti-HTTG) were significantly higher in patients than in controls (p = 0.000). The correlation studies established the negative correlation of anti-HTTG IgA with serum iron (r = -0.991, p = 0.000), hematocrit (r = -0.967, p = 0.000) and MCV (r = -0.946, p = 0.000) in patients. The serum iron was remarkably reduced in CD patients. A negative correlation was found between anti-HTTG IgA and serum iron, while a positive serum iron was correlated with hematocrit and MCV in CD patients.

Tamarix articulata Induced Prevention of Hepatotoxicity Effects of In Vivo Carbon Tetrachloride by Modulating Pro-Inflammatory Serum and Antioxidant Enzymes to Reverse the Liver Fibrosis.

This study evaluates the hepatoprotective activity of a Tamarix articulata extract against carbon tetrachloride-mediated hepatotoxicity in Wistar rats. Our results demonstrated that the oral administration of Tamarix articulata extract (50 mg/kg b.w.) significantly restored the serum levels of liver enzymes and antioxidant parameters (superoxide dismutase, catalase, glutathione reductase, and thiobarbituric reactive substances). Histopathology analysis revealed that Tamarix articulata extract significantly reduced hepatic fibrosis by inhibiting the necrosis of hepatocytes. Furthermore, serum pro-inflammatory (tumor necrosis factor-alpha, tumor growth factor-beta, and interleukin-6) markers were significantly restored. However, the anti-inflammatory cytokine adiponectin levels increased to normal levels in the group treated with Tamarix articulata extract. Additionally, we observed diminished reactive oxygen species production and the depolarization of mitochondrial membrane potential in hepatocytes extracted from animal livers treated with Tamarix articulata extract. Our findings suggest that Tamarix articulata extract prevents liver fibrosis induced by carbon tetrachloride and decreases the necrotic population of hepatocytes. These events restored the antioxidant enzymatic activity, serum levels of liver enzymes, and pro-inflammatory markers to their normal levels.

Ebola virus infection induces a delayed type I IFN response in bystander cells and the shutdown of key liver genes in human iPSC-derived hepatocytes.

SummaryLiver damage and an exacerbated inflammatory response are hallmarks of Ebola virus (EBOV) infection. Little is known about the intrinsic response to infection in human hepatocytes and their contribution to inflammation. Here, we present an induced pluripotent stem cell (iPSC)-derived hepatocyte-like cell (HLC) platform to define the hepato-intrinsic response to EBOV infection. We used this platform to show robust EBOV infection, with characteristic ultrastructural changes and evidence for viral replication. Transcriptomics analysis revealed a delayed response with minimal early transcriptomic changes, followed by a general downregulation of hepatic function and upregulation of interferon signaling, providing a potential mechanism by which hepatocytes participate in disease severity and liver damage. Using RNA-fluorescence in situ hybridization (FISH), we showed that IFNB1 and CXCL10 were mainly expressed in non-infected bystander cells. We did not observe an inflammatory signature during infection. In conclusion, iPSC-HLCs are an immune competent platform to study responses to EBOV infection.

Elevated levels of serum glucose, triglyceride, and liver enzymes in a rat model of 7,12 dimethylbenz[a]anthracene (DMBA)-induced carcinogenesis

ABSTRACT Background: Uncontrolled cell proliferation in cancers has a high requirement of energy and biosynthetic substrates. Glucose and triglycerides are the main source of energy as well as the primary building blocks for forming cellular components of mammalian cells.Objective: This study aims to evaluate the shifting of serum glucose, triglyceride, and nitrogen wastes in the form of urea and creatinine levels; and liver enzymes levels, alanine transaminase (ALT) and aspartate aminotransferase (AST), in rat model carcinogenesis with a single dose of 7,12-dimethylbenzanthracene (DMBA) for 16 weeks observation..Methods: The experimental animals of Rattus norvegicus strain Sprague Dawley were divided into two groups, namely the control group and the DMBA-induced group. A blood chemistry examination was carried out at weeks 4, 8, 12, and 16 post-induction using a spectrophotometer. In addition, observation of breast tumor formation and histological examination of the tumor and organs, including liver, lung, intestine, and kidney, were performed to confirm cancer formation.Results: Five of the six experimental rats (83.3%) induced by DMBA experienced breast and lung cancer formation accompanied by continuous weight loss starting at week 10 after induction. Serum glucose levels increased significantly at weeks 12 and 16 after induction, while serum triglyceride, ALT, and AST levels increased significantly from week 4 after induction until the end of the experiment. Serum urea levels did not show a significant difference from the control group. Nonetheless, creatinine decreased at the last examination.Conclusion: Elevated serum glucose, triglycerides, ALT, and AST levels escorted the chemical carcinogen-induced cancer development. Studies at the clinical level are needed to prove whether abnormally elevated of these blood chemistry levels can be used to detect the presence of cancer early.Keywords:DMBA, breast cancer, lung cancer, cancer metabolism.

The association between obesity with serum levels of liver enzymes, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and gamma-glutamyl transferase in adult women.

Obesity-induced inflammation may independently disturb the function of critical organs such as liver. This study aimed to investigate the association of obesity with serum levels of biomarkers of liver function including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) in adult women. This cross-sectional study was carried out on 360 adult women in the summer of 2020 in Tehran, Iran. The participants were categorized into two groups based on their body mass index (BMI≤29.9 and BMI > 30). The serum levels of ALT, AST, ALP and GGT were measured. Logistic regression method was used to assess the association between BMI and liver enzymes after adjusting for the confounders. The mean BMI in non-obese and obese groups was 26.32 ± 2.61 and 33.40 ± 2.80 kg/m2 , respectively (p=.01). A significant association was found between BMI with ALT (β=.16, p=.002) and GGT (β=.19, p=.01) enzymes after adjustment for age. The association between BMI and GGT remained significant after further adjustments for smoking, alcohol use, physical activity and educational status. There was no significant association between BMI and liver enzymes after adjustment for dietary intake. Obesity was associated with the level of serum liver enzymes. However, adjustment for dietary intake disappeared the significant results. Further studies are needed to determine the independent effects of obesity on the liver function.

De Ritis Ratio and related Parameters among Breast Cancer Patients in a Southern Nigeria Population

De Ritis described the ratio between the serum levels of liver enzymes; aspartate transaminase (AST) and alanine transaminase (ALT). The central role of the liver in metabolism makes it a necessity that it functions optimally during chemotherapeutic administration, hence the consideration of associated parameters in the management of breast cancer. This study was conducted in University of Calabar Teaching Hospital, Calabar. It included 40 cases of pathologically diagnosed breast cancer female patients who were accessing post-operative chemotherapy. Another 40 apparently healthy females drawn from the general population served as controls. Ethical approval and written informed consent were duly sought and obtained. The present study measured the levels of total and conjugated bilirubin as well as the enzyme activities for a spartate aminotransferase, alanine aminotransferase and alkaline phosphatase. Additionally, Unconjugated bilirubin derived from total and conjugated bilirubin as well as De Ritis ratio computed from aspartate aminotransferase and alanine aminotransferase were calculated. Standard colorimetric methods were used to determine the measured parameters, while derived parameters were calculated. The data obtained were analyzed in Statistical Package for Social Sciences (SPSS) using students t-test at 95% confidence level with p-value of ≤ 0.05. Apart from alanine aminotransferase that of the chemotherapy courses showed some observable effect on both derived parameters; Unconjugated Bilirubin and De Ritis ratio. The later showed a stable pattern of increment after commen cement of post-operative chemotherapy. This study indicates that routine assessment of hepatic function and De Ritis ratio should be determined as part of breast cancer management.

The effects of vitamin B12 supplementation on metabolic profile of patients with non-alcoholic fatty liver disease: a randomized controlled trial

The present study is the first effort to evaluate the effects of vitamin B12 supplementation on the serum level of liver enzymes, homocysteine, grade of hepatic steatosis, and metabolic profiles in patients with non-alcoholic fatty liver disease (NAFLD). Forty patients with NAFLD were enrolled in a double-blind placebo-controlled trial to receive either one oral tablet of vitamin B12 (1000 µg cyanocobalamin) or a placebo per day for 12 weeks. We investigated serum levels of homocysteine, aminotransferases, fasting blood glucose (FBG), lipids, malondialdehyde (MDA), and homeostasis model assessment of insulin resistance (HOMA-IR). The grade of liver steatosis and fibrosis was measured by real-time 2-dimensional shear wave elastography. Vitamin B12 supplementation significantly decreased serum levels of homocysteine compared to placebo (medians: − 2.1 vs. − 0.003 µmol/l; P = 0.038). Although serum alanine transaminase (ALT) in the vitamin B12 group decreased significantly, this change did not reach a significant level compared to the placebo group (medians: − 7.0 vs. 0.0 IU/l; P > 0.05). Despite the significant within-group decrease in FBG, MDA, and liver steatosis in the vitamin B12 group, between-group comparisons did not reveal any significant difference. Vitamin B12 supplementation might decrease serum levels of homocysteine in patients with NAFLD. The fasting blood glucose and serum levels of MDA were significantly improved in the trial group who received vitamin B12. However, these changes did not reach a significant level compared to the placebo group. In this respect, further studies with larger sample sizes, different doses, and types of vitamin B12 will reveal additional evidence.Trial Registration: At http://irct.ir/ as IRCT20120718010333N5 on December 25, 2019.

Galangin Nanoparticles Protect Acetaminophen-Induced Liver Injury: A Biochemical and Histopathological Approach.

One of the main causes of acute liver failure is overdose with acetaminophen. Excessive consumption of acetaminophen leads to the production of NAPQI (N-acetyl-p-benzoquinone imine) through the activity of the enzyme cytochrome c oxidase. For this purpose, the effect of galangin nanoparticles with antioxidant activities will be evaluated for the treatment of acetaminophen-induced hepatotoxicity. In this study, after the synthesis of galangin nanoparticles and particle size determination, mice were divided into six groups. Before treatment, a single dose (350 mg/kg) of acetaminophen was administered by gavage in all groups. The activity of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), as well as biochemical factors FRAP and MDA in serum were measured and a histopathological study was performed. The prepared nanoparticles produced in this research were characterized by the SEM, DLS, and ZETA potential, and the average particle size was obtained in the range of 150 nm. Serum levels of liver enzymes (AST and ALT) in the nanoparticle group decreased significantly compared with the control group (P < 0.05). In the group without treatment, the activity of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) enzymes increased significantly compared with the treatment groups. Also, galangin nanoparticles, at a dose of 20 mg/kg, improve cell damage in hepatocytes and preserve the tissue structure of the liver. Galangin nanoparticles reduce the acetaminophen-induced hepatotoxicity by reducing the number of liver function indices. According to our findings, the liver-protective effects of the nanoparticle may be due to its antioxidant properties.

Ecotoxicological impacts of industrial effluents on irrigation water quality, animal health and the role of calcium alginate in effluents treatment

The effluents discharged from Mansoura Company for Resins and Chemicals Industry were evaluated for drinking and irrigation purposes. Calcium-alginate beads were used for effluents treatment in this study. Young male rats were also allowed to drink effluents at different concentrations (10%, 50%, 100%) and treated 100% effluents with calcium-alginate for 11 weeks. Results indicated high concentrations of some physicochemical parameters and Cd, Co, Fe, Mn, Ni, Pb, and Zn in effluents that exceeded the permissible limits for drinking and irrigation purposes. Treatment by calcium-alginate alleviate heavy metals concentration but did not affect the physicochemical parameters. Depending on effluents concentration, the liver of young male rats showed high accumulation of Fe, Mn, Zn, Pb, Cd, Co, Cu, Cr, and Ni compared to the control group. Serum levels of liver enzymes, total bilirubin significantly increased while total protein, and albumin contents decreased in effluent groups. Liver concentrations of malondialdehyde and protein carbonyl significantly elevated along with significant decrease in superoxide dismutase, catalase, glutathione-S-transferase activities, and glutathione content. Moreover, growth and thyroid hormones were significantly reduced along with significant elevation in thyroid stimulating hormone. This was accompanied by significant decrease in the body weight, especially with 100% effluents concentration compared to control group. Also, histological investigations of both liver and thyroid gland using hematoxylin and eosin showed distortion in the structure of both organs especially with 50% and 100% effluent groups. However, treatment of effluents by calcium-alginate improved these changes. The study revealed that calcium-alginate are effective biosorbents for heavy metals and consequently decrease animal and human health hazards, but further studies are needed to alleviate physicochemical characteristics.

Gut Commensal Fungi Protect Against Acetaminophen-Induced Hepatotoxicity by Reducing Cyp2a5 Expression in Mice.

Background and AimsDrug-induced liver injury (DILI) is a common cause of acute liver failure and represents a significant global public health problem. When discussing the gut-liver axis, although a great deal of research has focused on the role of gut microbiota in regulating the progression of DILI, the gut commensal fungal component has not yet been functionally identified.MethodsMice were pretreated with fluconazole (FC) to deplete the gut commensal fungi and were then subject to acetaminophen (APAP) gavage. In addition, transcriptome sequencing was performed to identify differentially expressed genes (DEGs) between control and fluconazole-pretreated groups of the mice challenged with APAP.ResultsGut commensal fungi ablation through fluconazole pretreatment predisposed mice to APAP-induced hepatotoxicity, characterized by elevated serum liver enzyme levels and more severe centrilobular necrosis, which appears to be caused by robust inflammation and oxidative stress. The 16S rDNA sequencing results indicated that Akkermansia muciniphila abundance had significantly decreased in gut fungi-depleted mice, whereas increased abundance of Helicobacter rodentium was observed. The gene interaction network between DEGs identified by the transcriptome sequencing highlighted a significant enrichment of Cyp2a5 in the liver of APAP-treated mice that were preadministrated with fluconazole. Pharmacological inhibition of Cyp2a5 by 8-methoxypsoralen (8-MOP) could significantly attenuate hepatic inflammation and oxidative stress in mice, thereby conferring resistance to acute liver injury caused by APAP administration.ConclusionOur data highlighted the significance of gut commensal fungi in hepatic inflammation and oxidative stress of APAP mice, shedding light on promising therapeutic strategies targeting Cyp2a5 for DILI treatment.

Effectiveness and clinical benefits of new anti-diabetic drugs: A real life experience.

We evaluated the clinical impact, in daily clinical practice, of sodium-glucose co-transporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP1RA) therapies in patients with type 2 diabetes. Data from 500 unselected consecutive patients were retrospectively analyzed. Only those with a full assessment at baseline (T0) and after 3 (T3), 6 (T6), and 12 (T12) months of treatment with SGLT2i or GLP1RA were included in the study (n = 167). At baseline, patients had a high mean body weight (BW), abdominal circumference (AC), body mass index (BMI), and HOMA index. Despite normal C-peptide values, 39 patients were being treated with insulin (up to 120 IU/day). During therapy, a progressive improvement in BW, BMI, and AC was observed with both the molecules. Fasting glucose and glycated Hb decrease was already significant at T3 in all patients, while the HOMA index selectively improved with SGLT2i therapy. Renal function parameters remained stable regardless of the drug used. Finally, SGLT2i reduced serum uric acid and improved the lipid profile, while GLP1RA reduced serum levels of liver enzymes. Both the therapeutic regimens allowed a significant reduction or complete suspension of unnecessary insulin therapies. Our real life data confirm the results obtained from randomized clinical trials and should be taken as a warning against inappropriate use of insulin in patients with preserved β-cell function.

Cross-Species Transmission of Rabbit Hepatitis E Virus to Pigs and Evaluation of the Protection of a Virus-like Particle Vaccine against Rabbit Hepatitis E Virus Infection in Pigs.

We investigated the cross-species transmission of rabbit hepatitis E virus (rb HEV) to pigs and evaluated the cross-protection of a swine (sw) HEV-3 virus-like particle (VLP) vaccine against rb HEV infection in pigs. Twelve 4-week-old conventional pigs were divided into negative control (n = 3), positive control (rb HEV-infected, n = 4), and vaccinated (vaccinated and rb HEV-challenged, n = 5) groups. The vaccine was administered at weeks 0 and 2, and viral challenge was conducted at week 4. Serum HEV RNA, anti-HEV antibody, cytokine, and liver enzyme levels were determined. Histopathological lesions were examined in abdominal organs. Viral RNA was detected and increased anti-HEV antibody and alanine aminotransferase (ALT) levels were observed in positive control pigs; liver fibrosis, inflammatory cell infiltration in the lamina propria of the small intestine and shortened small intestine villi were also observed. In vaccinated pigs, anti-HEV antibody and Th1 cytokine level elevations were observed after the second vaccination; viral RNA was not detected, and ALT level elevations were not observed. The results verified the cross-species transmission of rb HEV to pigs and cross-protection of the sw HEV-3 VLP vaccine against rb HEV infection in pigs. This vaccine may be used for cross-protection against HEV infection in other species.

The effect of a fruit-rich diet on liver biomarkers, insulin resistance, and lipid profile in patients with non-alcoholic fatty liver disease: a randomized clinical trial

Background Despite confirmed dietary approaches to improve the Non-Alcoholic Fatty Liver Disease (NAFLD), the effect of fruits on NAFLD is not clear. The present study aimed to investigate the effect of a fruit rich diet (FRD) on liver steatosis, liver enzymes, Insulin resistance, and lipid profile in patients with NAFLD. Methods Eighty adults with NAFLD participated in this randomized controlled trial. The participants were randomly assigned to the FRD group with consumption of at least 4 servings of fruits daily or the control group with fruits consumption of less than 2 servings/day. The grade of steatosis, serum levels of liver enzymes including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT), total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), glucose, and homeostatic model assessment for insulin resistance (HOMA-IR) were measured at the baseline and at the end of the study. Results After 6 months of intervention, the FRD group had significantly higher BMI (31.40 ± 2.61 vs. 25.68 ± 2.54, p < .001), WC (113.5 ± 10.7 vs. 100.5 ± 7.5, p < .001), the grade of steatosis, ALT (89.1 ± 92.9 vs. 32.0 ± 19.2, p < .001), AST (74.5 ± 107.8 vs. 24.0 ± 8.5, p < .001), ALP (273.4 ± 128.5 vs. 155.0 ± 43.9, p < .001), GGT (92.7 ± 16.2 vs. 21.2 ± 7.7, p < .001), TC (206.1 ± 40.5 vs. 172.7 ± 42.4, p < .01), LDL (126.9 ± 32.3 vs. 99.8 ± 29.8, p < .001), glucose (115.5 ± 30.0 vs. 97.7 ± 19.0, p < .01), and insulin resistance (7.36 ± 4.37 vs. 2.66 ± 1.27, p < .001), and lower HDL (41.4 ± 8.9 vs. 53.8 ± 15.1, p < .001) compared to the control group. Adjusting for BMI and calorie intake did not change the results. Conclusion The results of the present study indicated that consumption of fruits more than 4 servings/day exacerbates steatosis, dyslipidemia, and glycemic control in NAFLD patients. Further studies are needed to identify the underlying mechanisms of the effects of fruits on NAFLD.
