RESUMO

BACKGROUND: The effects of anesthetics on liver and kidney functions after infantile living-related liver transplantation (LRLT) are unclear. This study aimed to investigate the effects of propofol-based total intravenous anesthesia (TIVA) or desflurane-based inhalation anesthesia on postoperative liver and kidney functions in infant recipients after LRLT and to evaluate hepatic ischemia-reperfusion injury (HIRI). METHODS: Seventy-six infants with congenital biliary atresia scheduled for LRLT were randomly divided into two anesthesia maintenance groups: group D with continuous inhalation of desflurane and group P with an infusion of propofol. The primary focus was to assess alterations of liver transaminase and serum creatinine (Scr) levels within the first 7 days after surgery. And the peak aminotransferase level within 72 h post-surgery was used as a surrogate marker for HIRI. RESULTS: There were no differences in preoperative hepatic and renal functions between the two groups. Upon the intensive care unit (ICU) arrival, the levels of aspartate aminotransferase (AST, P = 0.001) and alanine aminotransferase (ALT, P = 0.005) in group P were significantly lower than those in group D. These changes persisted until the fourth and sixth days after surgery. The peak AST and ALT levels within 72 h after surgery were also lower in group P than in group D (856 (552, 1221) vs. 1468 (732, 1969) U/L, P = 0.001 (95% CI: 161-777) and 517 (428, 704) vs. 730 (541, 1100) U/L, P = 0.006, (95% CI: 58-366), respectively). Patients in group P had lower levels of Scr upon the ICU arrival and on the first day after surgery, compared to group D (17.8 (15.2, 22.0) vs. 23.0 (20.8, 30.8) µmol/L, P < 0.001 (95% CI: 3.0-8.7) and 17.1 (14.9, 21.0) vs. 20.5 (16.5, 25.3) µmol/L, P = 0.02 (95% CI: 0.0-5.0) respectively). Moreover, the incidence of severe acute kidney injury was significantly lower in group P compared to that in group D (15.8% vs. 39.5%, P = 0.038). CONCLUSIONS: Propofol-based TIVA might improve liver and kidney functions after LRLT in infants and reduce the incidence of serious complications, which may be related to the reduction of HIRI. However, further biomarkers will be necessary to prove these associations.

RESUMO

BACKGROUND: Valvular heart disease (VHD) can cause damage to extra-cardiac organs, and lead to multi-organ dysfunction. However, little is known about the cardio-renal-hepatic co-dysfunction, as well as its prognostic implications in patients with VHD. The study sought to develop a multi-biomarker index to assess heart, kidney, and liver function in an integrative fashion, and investigate the prognostic role of cardio-renal-hepatic function in VHD. METHODS: Using a large, contemporary, prospective cohort of 6004 patients with VHD, the study developed a multi-biomarker score for predicting all-cause mortality based on biomarkers reflecting heart, kidney, and liver function (N-terminal pro-B-type natriuretic peptide [NT-proBNP], creatinine, and albumin). The score was externally validated in another contemporary, prospective cohort of 3156 patients with VHD. RESULTS: During a median follow up of 731 (704-748) days, 594 (9.9%) deaths occurred. Increasing levels of NT-proBNP, creatinine, and albumin were independently and monotonically associated with mortality, and a weighted multi-biomarker index, named the cardio-renal-hepatic (CRH) score, was developed based on Cox regression coefficients of these biomarkers. The CRH score was a strong and independent predictor of mortality, with 1-point increase carrying over two times of mortality risk (overall adjusted hazard ratio [95% confidence interval]: 2.095 [1.891-2.320], P < 0.001). The score provided complementary prognostic information beyond conventional risk factors (C index: 0.78 vs 0.81; overall net reclassification improvement index [95% confidence interval]: 0.255 [0.204-0.299]; likelihood ratio test P < 0.001), and was identified as the most important predictor of mortality by the proportion of explainable log-likelihood ratio χ2 statistics, the best subset analysis, as well as the random survival forest analysis in most types of VHD. The predictive performance of the score was also demonstrated in patients under conservative treatment, with normal left ventricular systolic function, or with primary VHD. It achieved satisfactory discrimination (C index: 0.78 and 0.72) and calibration in both derivation and validation cohorts. CONCLUSIONS: A multi-biomarker index was developed to assess cardio-renal-hepatic function in patients with VHD. The cardio-renal-hepatic co-dysfunction is a powerful predictor of mortality and should be considered in clinical management decisions.

RESUMO

PURPOSE: This study aimed to evaluate the effect of prenatal diagnosis at different gestational times on the clinical features of patients with choledochal cysts (CDCs). METHODS: Medical records of patients with prenatally diagnosed CDCs admitted to our hospital (April 2013-April 2018) were retrospectively reviewed. The clinical characteristics and pathological CDC features were analyzed. RESULTS: Two hundred eighteen cases were included. Patients were divided into two groups. Group 1 and group 2 had a prenatal diagnosis at ≤ 27 weeks of gestation (second trimester of gestation, n = 157) and > 27 weeks (third trimester of gestation, n = 61), respectively. The incidence of jaundice and the TBIL, IBIL and GGT levels were higher in Group 1 (P = 0.021, P = 0.029, P = 0.042, P = 0.007, respectively). The maximum cyst diameter at the time of surgery was larger in Group 1 (P = 0.015). An association study showed that the time of prenatal diagnosis was negatively correlated with the maximum cyst diameter both postnatally (r = - 0.223, P = 0.001) and at the time of surgery (r = - 0.268, P < 0.001). CONCLUSION: Unlike patients diagnosed at a late prenatal age, patients diagnosed at an early prenatal age tend to present clinical symptoms (jaundice, manifested as high indirect bilirubin), hepatic function damage, and large cysts at the time of surgery.

RESUMO

Acetaminophen (APAP) is the most extensively used and safest analgesic and antipyretic drug worldwide; however, its toxicity is associated with life-threatening acute liver failure. Cardamom (CARD), a sweet, aromatic, commonly used spice, has several pharmacological actions. In the current study, we tried to explore the chemical composition and the hepato-protective effect of ethanolic aqueous extract of CARD to mitigate APAP-induced hepatic toxicity and elucidate its underlying mechanism of action. MATERIAL AND METHODS: Aqueous CARD extract was subjected to LC-TOF-MS analysis to separate and elucidate some of its components. In vivo animal experiments involved five groups of animals. In the normal and cardamom groups, mice were administered either saline or CARD (200 mg/kg), respectively, orally daily for 16 days. In the APAP group, the animals were administered saline orally daily for 15 days, and on the 16th day, animals were administered APAP (300 mg/kg) IP for the induction of acute hepatic failure. In the CARD 200 + APAP group, mice were administered CARD (200 mg/kg) for 15 days, followed by APAP on the 16th day. RESULTS: The aqueous extract of CARD showed several compounds, belonging to polyphenol, flavonoids, cinnamic acid derivatives and essential oil components. In the in vivo investigations, APAP-induced impaired liver function, several histopathological alterations, oxidative stress and inflammatory and apoptotic status signified severe hepatic failure. Whereas, pretreatment with the CARD extract prior to APAP administration diminished serum levels of the hepatic function test and augmented Nrf2 nucleoprotein and HO-1 and NQO-1. CARD down-regulated MDA, inflammatory mediators (IL-1ß, IL-6, TNF-α and NF-κB) and apoptotic markers (caspase 3 and 9 and Bax) and amplified the activities of SOD, catalase, GSH-Px and GSH-R in hepatic tissue samples. CONCLUSION: CARD extract mitigated the hepatic toxicity induced by APAP. The underlying mechanism of action of such hepato-protective action may be through upregulation of the Nrf2/HO-1/NQO-1 pathway with subsequent alleviation of the oxidative stress, inflammation and apoptosis induced by APAP. Many of the compounds identified in the CARD extract could be attributed to this pharmacological action of the extract.

RESUMO

BACKGROUND: Although living donor liver transplantation (LDLT) is the standard treatment option for patients with end-stage liver disease, it always entails ethical concerns about the risk of living donors. Recent studies have reported a correlation between sarcopenia and surgical prognosis in recipients. However, there are few studies of donor sarcopenia and the surgical prognosis of donors. This study investigated the association between sarcopenia and postoperative acute kidney injury in liver donors. METHODS: This retrospective study analysed 2892 donors who underwent donor hepatectomy for LDLT between January 2008 and January 2018. Sarcopenia was classified into pre-sarcopenia and severe sarcopenia, which were determined to be -1 standard deviation (SD), and -2 SD from the mean baseline of the skeletal muscle index, respectively. Multivariate regression analysis was performed to evaluate the association between donor sarcopenia and postoperative AKI. Additionally, we assessed the association between donor sarcopenia and delayed recovery of liver function (DRHF). RESULTS: In the multivariate analysis, donor sarcopenia was significantly associated a higher incidence of postoperative AKI (adjusted odds ratio [OR]: 2.65, 95% confidence interval [CI]: 1.15-6.11, P = .022 in pre-sarcopenia, OR: 5.59, 95% CI: 1.11-28.15, P = .037 in severe sarcopenia, respectively). Additionally, hypertension and synthetic colloid use were significantly associated with postoperative AKI. In the multivariate analysis, risk factors of DRHF were male gender, indocyanine green retention rate at 15 minutes, and graft type, however, donor sarcopenia was not a risk factor. CONCLUSIONS: Donor sarcopenia is associated with postoperative AKI following donor hepatectomy.

RESUMO

BACKGROUND AND AIM: Direct-acting antivirals (DAAs) have contributed to the improvement of outcomes for all patients with chronic hepatitis C. The aim of this study was to evaluate the long-term hepatic benefits of hepatitis C virus (HCV) cure by DAAs in patients with compensated cirrhosis. METHODS: This multicenter cohort study consisted of consecutive patients with compensated cirrhosis who initiated interferon-free DAA treatment before September 2016. The impact of treatment on long-term hepatic function was followed for at least 4 years after the end of treatment, and the progression to decompensation was evaluated. RESULTS: The data of 394 patients were available for study. The median age was 70, and 41% had modified albumin-bilirubin (ALBI) grade 2b. During a short-term follow-up 1 year after the end of treatment, FIB-4 index and ALBI score significantly improved. The achievement rates of FIB-4 < 3.25 (40%) and ALBI grade 1 (70%) reached their plateau in the first year; however, there were significant further improvements in platelet count and α-fetoprotein level after the first year. The annual incidence of decompensation was 1.30 (95% confidence interval 0.83-2.02) per 100 person-years. In multivariable analysis, male sex and modified ALBI grade 2b at baseline were associated with decompensation. CONCLUSIONS: In a large real-world cohort of patients with compensated cirrhosis treated with a DAA, remarkable improvement in hepatic function was seen after HCV cure, especially during the first year after the end of treatment. Treatment in the early stage of cirrhosis would be of great benefit for preventing liver deterioration to decompensation.

RESUMO

OBJECTIVE: This cross-sectional study investigated the association of periodontitis with the metabolic status and hepatic function in pregnant women. MATERIALS AND METHODS: Full-mouth periodontal conditions, metabolic profiles, and hepatic function were assessed in 219 self-reported healthy pregnant females. The association of periodontal status with the systemic parameters was evaluated by parametric and non-parametric tests, and multivariate logistic regression analysis. RESULTS: Overall, periodontal status was positively associated with the metabolic profiles and hepatic function test results. The subjects with periodontitis exhibited higher levels of body mass index (BMI) (p < 0.01) and serum aspartate transaminase (AST) (p < 0.05), elevated diastolic blood pressure (DBP) (p < 0.05), and lower levels of high-density lipoprotein cholesterol (p < 0.05) than those of the counterparts. The periodontitis severity was strongly correlated with BMI and AST levels, and the extent of periodontal inflammation was related to DBP (p < 0.01). The periodontitis patients at 34-36 gestational weeks showed higher blood pressure and AST levels than those of non-periodontitis subjects (p < 0.05). CONCLUSION: Our findings on the notable links of periodontitis to concurrent metabolic disorders and abnormal liver function in pregnant women highlight the need of proactive integration of regular periodontal screening and healthcare in maternal programs for promoting optimal health and wellbeing of mothers-to-be and newborns.

RESUMO

Some events of hepatotoxicity have been linked to consumption of green tea supplements. The association between consumption of green tea or green tea supplements and abnormal liver biomarkers in adults was investigated using cross-sectional data from the 2009-2014 United States National Health and Nutrition Examination Survey (U.S. NHANES). Individuals with levels of either bilirubin or GGT, ALT, AST, and/or ALP in excess of the age- and gender-specific upper limits of normal ranges were classified as having abnormal liver biomarkers. Associations between green tea or green tea supplement use (consumption vs. not) and liver function were determined using multiple logistic regression modelling. 12,289 persons were included in the green tea analyses and 12,274 in the green tea supplement analyses. The odds of having one or more abnormal liver biomarkers were significantly reduced (p = 0.01) with consumption of green tea (OR: 0.49; 95% CI: 0.28, 0.85), while no significant association (p = 0.78) was determined for consumption of green tea supplements (OR: 0.92; 95% CI: 0.52, 1.64). Based on data from the 2009-2014 U.S. NHANES, green tea consumption was associated with reduced odds of having one or more abnormal liver biomarkers; whereas, no significant association was determined with consumption of green tea supplements.

RESUMO

BACKGROUND: Platelet index was reported to be used as a potential prognostic marker in patients with liver fibrosis. We aimed to explore the association between plateletcrit (PCT) and severity of hepatic sinusoidal obstruction syndrome (HSOS). METHODS: Seventy consecutive patients who diagnosed as HSOS by CT and medical history during January 2017-November 2021 were included. All patients were divided into two groups which confirmed as favorable prognosis and poor prognosis on the basis of Child-Turcotte-Pugh score system. The clinical manifestation and laboratory parameters of two groups were retrospectively selected. PCT was evaluated within two groups, and the diagnostic accuracy was evaluated by the area under the receiver operating characteristic curve. RESULTS: The significant difference between the two groups not only in diarrhea, abdominal pain, abdominal distention, urine volume, and skin ecchymosis (p < 0.005), but also in WBC count, NE count, PLT count, TBIL, and D-Dimer (p < 0.005) were found. The PCT level was significantly higher in HSOS patients with poor prognosis (0.169 ± 0.060) than favorable prognosis patients (0.110 ± 0.047). The area under the receiver operating characteristic curve of RDW in predicting poor prognosis was 0.781, with 67.70% sensitivity and 79.5%specificity. CONCLUSIONS: The PCT level was correlated positively with the poor prognosis in HSOS patients. PCT can be a promising indicator for predicting prognosis in HSOS.

RESUMO

Alcohol dependence is one of the main reasons for inpatient admission to psychiatric hospitals. The abuse of this chemical substance can cause modifications in our organism and among them, variations in the oxidative stress parameters. Therefore, the aim of this study is to evaluate patients admitted to a psychiatric hospital unit to treat alcohol dependence, comparing oxidative stress, renal and hepatic function parameters from the moment of admission to those obtained at discharge. Hepatic function was verified through gamma-glutamyl-transferase (GGT), alkaline-phosphatase (ALP), aspartate-aminotransferase (AST) and alanine-aminotransferase (ALT) activity measurements. Urea and creatinine serum levels were measured for kidney function evaluation. Oxidative stress was evaluated by superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), ferric reducing antioxidant power (FRAP) and malondialdehyde (MDA). Medications used during hospital stay were record and their influence over the measured parameters analyzed. Twenty-eight patients (82% male, 44 ± 13 years old) were included in this study. A significant increase in BMI of patients after the period of hospitalization could be observed. There were reductions in creatinine, AST, ALT, GGT and ALP serum levels. SOD levels were lower at discharge, while GPx and FRAP presented higher levels. Chlorpromazine use showed influence over some hepatic function markers (ALT, GGT and ALP) and oxidative stress parameters (CAT and GPx); while carbamazepine use influenced GGT and FRAP. Patients on alcohol dependence treatment had significant improvements of renal and hepatic function parameters and higher GPx and FRAP values after the hospitalization period, which indicates reversion of alcohol effects over oxidative stress parameters.

RESUMO

Ethnopharmacological relevance: Oxidative stress is a key player in intestinal ischemia/reperfusion (I/R) injury (IIRI) with a tendency to trigger systemic inflammatory response, resulting in progressive distal organ injury. To date, the role of Bax/caspase 3 signaling in IIRI has not been reported. Furthermore, the discovery of a safe and effective drug remains pertinent in improving the outcome of IIRI. Therefore, this study investigated the role of Bax/caspase 3 signaling in intestinal I/R-induced intestinal and hepatic injury. In addition, the protective effect and possible associated mechanism of action of methanolic Phyllanthus amarus leaf extract (PA) against intestinal I/R-induced intestinal and hepatic injury were evaluated. Materials and methods: Fifty male Wistar rats were randomized into five groups (n = 10). The sham-operated group was received 0.5 mL of distilled water for seven days prior to the sham surgery, while the IIRI, febuxostat (FEB) + IIRI, low-dose PA (LDPA) + IIRI, and high-dose PA (HDPA) + IIRI groups underwent the I/R procedure. In addition to the procedure, IIRI, FEB + IIRI, LDPA + IIRI, and HDPA + IIRI received 0.5 mL of distilled water, 10 mg/kg of febuxostat, 200 mg/kg of PA, and 400 mg/kg of PA, respectively, for seven days prior to the I/R procedure. Results: Administration of methanolic Phyllanthus amarus leaf extracts attenuated the intestinal I/R-induced rise in intestinal and hepatic injury markers, malondialdehyde, nitric oxide, TNF-α, IL-6, and myeloperoxidase activities. In addition, Phyllanthus amarus ameliorated I/R-induced suppression of reduced glutathione, thiol and non-thiol proteins, and superoxide dismutase, catalase, and glutathione peroxidase activities in intestinal and hepatic tissues. These were coupled with the suppression of I/R-induced bacterial translocation, downregulation of I/R-induced activation of Bax/caspase 3 signaling, and improvement of I/R-induced distortion of intestinal and hepatic histoarchitecture by Phyllanthus amarus. Conclusion: Methanolic Phyllanthus amarus leaf extract protects against intestinal and hepatic injuries associated with intestinal I/R by suppressing oxidative-stress-mediated activation of Bax/caspase 3 signaling. The beneficial effects of Phyllanthus amarus may be ascribed to its constituent bioactive molecules, especially tannins, anthocyanin, alkaloids, and phenolics.

RESUMO

CONTEXT: Non-alcoholic fatty liver disease (NAFLD), the most common chronic liver disease, can develop into metabolic associated fatty liver disease (MAFLD). Gypenosides (GP), the main phytochemical component of Gynostemma pentaphylla (Thunb.) Makino (Cucurbitaceae), have been applied for treatment of metabolic diseases. OBJECTIVE: We investigate how GP modulate MAFLD-related hepatic steatosis and intestinal barrier injury. MATERIALS AND METHODS: In cell experiments, Caco-2 cells were treated with GP (150 or 200 µmol/L, 24 h), following lipopolysaccharide (LPS) exposure (10 µg/mL, 24 h) to mimic MAFLD in vitro. In in vivo experiments, control, model and model + GP groups were set. High fructose diet/high fat (HFD/HF)-fed (12 weeks) MAFLD rats received GP treatment (300 mg/kg, 6 weeks), followed by intra-peritoneal glucose tolerance test and histopathological examination of rat liver and intestinal mucosa using haematoxylin-eosin staining. RESULTS: GP at 200 µM significantly reversed LPS-induced decreases in transepithelial electrical resistance (TER) value (25%), protein expression of occludin (two fold) and ZO-1 (four fold), and the ratio of p-AMPK to AMPK (five fold), while partially repressing LPS-induced leakage of FD4 (50%) and LPS-induced increases in the Toll-like receptor 4 (TLR4) level (50%) and the ratio of p-p65 to p65 (55%). Compared with the model rats, rats with GP treatment presented a reduction in gain of weight and glucose tolerance. In addition, GP alleviated HFD/HF-induced histopathological abnormalities in rat liver and intestinal mucosa. CONCLUSIONS: GP attenuates hepatic steatosis and intestinal barrier injury in MAFLD rats via the AMPK and TLR4/nuclear factor kappa B (NF-κB) pathways, providing a potential treatment for MAFLD patients.

RESUMO

Most physiological changes follow a daily cycle in animals because their circadian rhythm is adjusted to and synchronized with sunlight. In particular, the circadian rhythm affects liver functions, including pharmacokinetics and metabolism. The influence of circadian rhythm has not been included in hepatotoxicity assays used in drug discovery and development. In this study, the contribution of circadian rhythm was investigated in acetaminophen-induced hepatotoxicity in mice and primary cultured hepatocytes. Hepatotoxicity was induced via the intraperitoneal administration of acetaminophen to a greater extent at night than during the day in mice. The sensitivity of acetaminophen-induced hepatotoxicity was consistent with the expression levels of acetaminophen-metabolizing enzyme and circadian genes. The host-derived circadian rhythm was still evident in the primary cultured hepatocytes within a day after their isolation from the liver. Primary cultured hepatocytes isolated at night were significantly more sensitive to acetaminophen than those isolated during the day. The sensitivity toward acetaminophen-induced hepatotoxicity depended on the circadian rhythm of the expression of acetaminophen-metabolizing genes and intracellular glutathione levels in primary cultured hepatocytes. These results obtained from cultured cells correspond to those in mice, suggesting that the timing of hepatocyte isolation is important when investigating drug metabolism and toxicity tests in culture.

RESUMO

This study tested the possible protective and therapeutic effects of Viscum album extract and probiotics against carbon tetrachloride (CCl4)-induced acute/chronic liver injury. Male Wistar rats were assigned to seven groups: Control, acute CCl4, acute V. album + CCl4, acute V. album + Probiotics + CCl4, chronic CCl4, chronic CCl4 + V. album, and chronic CCl4 + V. album + Probiotics. Acute and chronic liver injuries were induced by 2 mg/kg CCl4 (i.p.) and 1 mg/kg CCl4 (i.p.), respectively. The extract and probiotics were administered daily to related groups. Serum enzyme activities, lipid profile, total protein, albumin, bilirubin, heme oxgenase-1 and 8-hydroxydeoxyguanosine levels were measured. Liver tissue sections stained with Hematoxylin-Eosin. Acute or chronic CCl4-exposure caused to significant changes in concentrations/activities of the measured parameters. The oral administration of extract and probiotics showed protective and therapeutic effects against CCl4-induced liver-injury.

RESUMO

Previous studies have suggested that sodium-glucose co-transporter-2 (SGLT2) inhibitors may improve hepatic function; however, the evidence is scarce. Hence, we performed a meta-analysis of randomized controlled trials to evaluate the effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on hepatic parameters. PubMed, Web of Science, Scopus, and Google Scholar databases were searched to identify randomized controlled trials examining the effect of SGLT2 inhibitors on hepatic parameters. Meta-analysis was performed using a random-effects model and sensitivity analysis. Meta-analysis revealed that SGLT2 inhibitors therapy significantly lowered alanine aminotransferase (ALT) (WMD: -4.79 U/L, 95 % CI: -6.10, -3.47, I2 = 62 %, p < 0.00001), aspartate aminotransferase (AST) (WMD: -2.49 U/L, 95 % CI: -3.30, -1.68, I2 = 54 %, p < 0.00001), alkaline phosphatase (AP) (WMD: -1.13 U/L, 95 % CI: -2.03, -0.22, I2 = 23 %, p = 0.02), and gamma-glutamyl transferase (GGT) (WMD: -7.77 U/L, 95 % CI: -9.33, -6.21, I2 = 5 %, p < 0.00001). Additionally, SGLT2 inhibitors showed a significant increase in bilirubin levels (WMD: 0.64 U/L, 95 % CI: 0.27, 1.00, I2 = 53 %, p < 0.0006. Finally, no significant changes were found on albumin levels (WMD: 0.13 U/L, 95 % CI: -0.06, 0.32, I2 = 53 %, p < 0.0006) after SGLT2 inhibitors treatment. In conclusion, our results suggest that treatment with SGLT2 inhibitors exerts a beneficial effect on liver function tests through decreased ALT, AST, AP, and GGT concentrations.

RESUMO

Drug-induced liver injury (DILI) is the major reason for failures in drug development and withdrawal of approved drugs from the market. Two-dimensional cultures of hepatocytes often fail to reliably predict DILI: hepatoma cell lines such as HepG2 do not reflect important primary-like hepatic properties and primary human hepatocytes (pHHs) dedifferentiate quickly in vitro and are, therefore, not suitable for long-term toxicity studies. More predictive liver in vitro models are urgently required in drug development and compound safety evaluation. This review discusses available human hepatic cell types for in vitro toxicology analysis and their usage in established and emerging three-dimensional (3D) culture systems. Generally, 3D cultures maintain or improve primary hepatic functions (including expression of drug-metabolizing enzymes) of different liver cells for several weeks of culture, thus allowing long-term and repeated-dose toxicity studies. Spheroid cultures of pHHs have been comprehensively tested, but also other cell types such as HepaRG benefit from 3D culture systems. Emerging 3D culture techniques include usage of induced pluripotent stem-cell-derived hepatocytes and primary-like upcyte cells, as well as advanced culture techniques such as microfluidic liver-on-a-chip models. In-depth characterization of existing and emerging 3D hepatocyte technologies is indispensable for successful implementation of such systems in toxicological analysis.

RESUMO

AIM: The objective of this meta-analysis was to evaluate the effect of ursodeoxycholic acid (UDCA) therapy on serum liver function tests. METHODS: PubMed, Web of Science, Scopus and Google Scholar databases were searched to identify randomized placebo-controlled trials assessing the impact of UDCA on hepatic parameters. Meta-analysis was conducted using a random-effects model and sensitivity analysis through the leave-one-out method in the Review Manager statistical software version 5.3. RESULTS: After UDCA treatment, meta-analysis revealed a significant reduction of alanine aminotransferase (weighted mean difference [WMD]: -15.28 U/L, 95% confidence interval [CI]: -23.42, -7.15, P = 0.0002, I2 = 97%), aspartate aminotransferase (WMD: -16.13 U/L, 95% CI: -23.84, -8.42, P < 0.0001, I2 = 97%), gamma-glutamyl transferase (WMD: -23.29 U/L, 95% CI: -33.97, -12.61, P < 0.0001, I2 = 97%), alkaline phosphatase (WMD: -93.80 U/L, 95% CI: -126.36, -61.25, P < 0.0001, I2 = 95%) and bilirubin (WMD: -0.18 U/L, 95% CI: -0.35, -0.01, P = 0.04, I2 = 93%), but not significant changes in albumin levels (WMD: 0.10 U/L, 95% CI: -0.05, 0.24, P = 0.18, I2 = 80%). CONCLUSION: The results of the present meta-analysis suggest a hepatoprotective effect of UDCA by reducing serum liver parameters.

RESUMO

Heme oxygenase (HO) is a critical component of the defense mechanism to a wide variety of cellular stressors. HO induction affords cellular protection through the breakdown of toxic heme into metabolites, helping preserve cellular integrity. Nonalcoholic fatty liver disease (NAFLD) is a pathological condition by which the liver accumulates fat. The incidence of NAFLD has reached all-time high levels driven primarily by the obesity epidemic. NALFD can progress to nonalcoholic steatohepatitis (NASH), advancing further to liver cirrhosis or cancer. NAFLD is also a contributing factor to cardiovascular and metabolic diseases. There are currently no drugs to specifically treat NAFLD, with most treatments focused on lifestyle modifications. One emerging area for NAFLD treatment is the use of dietary supplements such as curcumin, pomegranate seed oil, milk thistle oil, cold-pressed Nigella Satvia oil, and resveratrol, among others. Recent studies have demonstrated that several of these natural dietary supplements attenuate hepatic lipid accumulation and fibrosis in NAFLD animal models. The beneficial actions of several of these compounds are associated with the induction of heme oxygenase-1 (HO-1). Thus, targeting HO-1 through dietary-supplements may be a useful therapeutic for NAFLD either alone or with lifestyle modifications.

RESUMO

OBJECTIVE: To investigate the relationship between myocardial enzymes, liver function and metabolic acidosis in children with rotavirus infection diarrhea. METHODS: The data of 70 children with infectious diarrhea treated in Baoding Children's Hospital, China, from October 2017 to April 2018 were retrospectively studied. The antigen of rotavirus in feces was positive by colloidal gold method. According to the clinical features of biochemical indicators and mental status, the patients were divided into four groups, an acidosis-free group, a mild acidosis group, a moderate acidosis group and a severe acidosis group, in line with acidosis severity. In addition to detecting the hepatic functions of the pediatric patients in the four groups, including aspartate aminotransferase (AST), alanine aminotransfer (ALT) levels, and myocardial enzyme levels (e.g., creatine kinase, or CK, and creatine kinase isoenzyme, or CK-MB), the relationships of hepatic function, myocardial enzyme levels and acidosis severity of the patients with infectious diarrhea caused by rotavirus infection were also analyzed. RESULTS: There was no significant difference in sex and age among the four groups (P>0.05). However, there was a significant difference in the frequency of diarrhea and vomiting (p<0.05). In addition, there were significant differences in creatine kinase, CK-MB, AST and ALT levels in children with metabolic acidosis of different severities. CONCLUSION: With the aggravation of metabolic acidosis, infectious diarrhea caused by rotavirus is characterized by the aggravation of hepatic function and myocardial cells.

RESUMO

BACKGROUND: Quality of life (QOL) assessments with the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30, QLQ-HCC18, C30 and HCC18 index scores have been shown to be prognostic factors for overall survival (OS) in patients with hepatocellular carcinoma (HCC), independent of disease stage and liver function. Liver function parameters (including bilirubin, albumin, international normalized ratio [INR], Child-Pugh class, ALBI grade, MELD, alkaline phosphatase [ALP]-to-platelet ratio, albumin-to-ALP ratio) have also been found to be independent prognostic factors for OS in HCC patients. There has been scanty data on whether QOL and baseline liver function per se are correlated in HCC patients. This study investigates the correlations between baseline QOL data and liver function variables in HCC patients. METHODS: From 2007 to 2011, 517 patients were enrolled. Baseline QOL was assessed at diagnosis using the EORTC QLQ-C30 and QLQ-HCC18; thereafter C30 and HCC18 index scores were derived. Clinical and laboratory data were collected. For liver function assessment, Child-Pugh class, ALBI grade, MELD, ALP-to-platelet ratio and albumin-to-ALP ratio were derived. Correlation analyses were performed between QOL and liver function data. RESULTS: Complete QOL data were available in 472 HCC patients. After adjusting for clinical variables, significant correlations were found between QOL (QLQ-C30 and QLQ-HCC18) and dichotomized liver function variables (including Child-Pugh class, ALBI grade and the presence of ascites). It was demonstrated that QOL had significant and potentially clinically important correlations with continuous liver function variables (albumin, bilirubin, ALP and albumin-to-ALP ratio), with the highest Spearman's rank correlation coefficient (rho) exceeding 0.4. HCC18 and C30 index scores were also significantly correlated with these liver function variables. HCC18 index score, which had rho up to 0.37, generally performed better than C30 index score, which had rho up to 0.33. CONCLUSIONS: In HCC patients, baseline QOL assessment (using EORTC QLQ-C30, QLQ-HCC18, C30 index-score or HCC18 index-score) is significantly correlated with liver function. Based on the findings of this study, future trials are warranted to assess whether treatment to enhance liver function could improve HCC patients' QOL.
