[PMID: 32896504 DOI: 10.1016/j.clinre.2020.07.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 06/30/2020] [Accepted: 07/12/2020] [Indexed: 02/04/2023]
Abstract
OBJECTIVE To determine whether early, short-term, low-dose glucocorticoid treatment prevents the progression of severe acute exacerbation of chronic hepatitis B to liver failure. METHODS We prospectively enrolled 125 patients with severe acute exacerbation of chronic hepatitis B from the Department of Infectious Diseases, Third Affiliated Hospital of Sun Yat-sen University between September 2013 and March 2016. The patients were randomized to a hormone group (3-day, low-dose glucocorticoid treatment plus conventional treatment; 63 patients) and a control group (conventional treatment only; 62 patients). We analyzed markers of liver function, complications, mortality rates, and duration and cost of hospitalization. RESULTS Serum alanine transaminase levels were significantly lower in the hormone group than in the control group at 3 days (P = 0.009) and 1 week (P = 0.018) after treatment. The decrease in this level from the baseline value on day 3 was greater in the hormone group than in the control group (P = 0.023). The trend of the changes in this level significantly differed between the two groups (P = 0.008). The incidence of liver failure (8.06% vs. 30.16%; P = 0.002) and the duration of hospitalization (23.79 vs. 31.79 days; P = 0.031) were significantly lower in the hormone group than in the control group. CONCLUSION Low-dose, short-term glucocorticoid treatment early in the course of severe acute exacerbation of chronic hepatitis B along with conventional treatment significantly reduced the risk of progression to liver failure and shortened the duration of hospitalization, without increasing the complication rate.

Abstract
BACKGROUND Hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) is a severe condition with high mortality due to lack of efficient therapy. Until now, the use of methylprednisolone (MP) in HBV-ACLF is still controversial. We aimed to evaluate the efficacy and safety of MP in HBV-ACLF. METHODS Totally 171 HBV-ACLF patients from three medical centers were randomly allocated into MP group (83 patients treated with MP intravenously guttae for 7 days plus standard treatment: 1.5 mg/kg/day [day 1-3], 1 mg/kg/day [day 4-5], and 0.5 mg/kg/day [day 6-7]) and control group (88 patients treated with standard treatment). The primary endpoints were 6-month mortality and prognostic factors for 6-month survival. The survival time, cause of death, adverse events, liver function, and HBV DNA replication were analyzed. RESULTS The 6-month mortality was significantly lower in MP group than control group [32.4% vs. 42.5%, P = 0.0037]. MP treatment was an independent prognostic factor for 6-month survival [HR (95% CI) 0.547(0.308-0.973); P = 0.040]. Factors associated with reduced 6-month mortality in MP group included HBV DNA and lymphocyte/monocyte ratio (LMR) (P < 0.05). Based on ROC curve, LMR+MELD had a better predictive value for prognosis of HBV-ACLF under MP treatment. No significant difference in HBV DNA replication was observed between groups (P > 0.05). CONCLUSIONS MP therapy is an effective and safe clinical strategy in HBV-ACLF, increasing the 6-month survival rate.

Methylprednisolone Decreases Mitochondria-Mediated Apoptosis and Autophagy Dysfunction in Hepatocytes of Experimental Autoimmune Hepatitis Model via the Akt/mTOR Signaling.

Abstract
Autoimmune hepatitis (AIH) is characterized by massive immune cell-mediated hepatocyte destruction. Glucocorticoids, particularly methylprednisolone (MP), are the most effective treatment for AIH; however, the mechanism underlying the effects of glucocorticoid treatment has not been fully elucidated. The present study explored the effects of MP on damaged hepatocytes in mice with concanavalin A (ConA)-induced experimental autoimmune hepatitis (EAH). C57BL/6 mice were divided into three groups: a normal control group (injected with normal saline), a ConA (20 mg/kg) group, and a ConA + MP (3.12 mg/kg) group. The serum levels of liver enzymes, cytokines, activated T cells, and apoptosis- and autophagy-associated marker proteins were determined 12 h after ConA injection. Human hepatocyte cell line LO2 was used to verify the effects of ConA and MP in vitro. MP treatment significantly decreased inflammatory reactions in the serum and liver tissues and activated the Akt/mTOR signaling pathway to inhibit apoptosis and autophagy in hepatocytes in vivo. Transmission electron microscopy (TEM) revealed fewer autophagosomes in the MP-treated group than in the ConA-treated group. MP treatment obviously suppressed apoptosis and mitochondrial membrane potential (ΔΨm) loss in hepatocytes in vitro. Furthermore, ConA treatment increased the levels of LC3-II, p62/SQSTM1, and Beclin-1, while bafilomycin A1 did not augment the levels of LC3-II. MP treatment decreased the levels of LC3-II, p62/SQSTM1, and Beclin-1 and upregulated the levels of phosphorylated (p)-Akt and p-mTOR. In conclusion, MP ameliorated mitochondria-mediated apoptosis and autophagy dysfunction in ConA-induced hepatocyte injury in vivo and in vitro via the Akt/mTOR signaling pathway.

Abstract
Testicular torsion is a consequence of spermatic cord twisting which causes progressive damage to the structure of the testis and reduces sperm quality and usually results in infertility. In the present study, with the assumption of the protective effects of L-carnitine and betamethasone against ischemia-reperfusion (IR) injuries, their effects on twisted testicles were evaluated and compared. Twenty Wistar rats were randomly divided into four groups and used in this study. Except for the Sham (S) group, testicular IR was induced surgically in three other groups, including Control (C), Betamethasone (BM), and L-carnitine (LC) groups. Betamethasone and L-carnitine were injected before detorsion in the BM and LC groups, respectively. After twelve hours of reperfusion, the testicles were detached, and prepared for sperm parameters evaluation such as sperm count, motility, viability, morphology, and chromatin quality, and histopathologic evaluations, including mean seminiferous tubular diameter (MSTD), germinal epithelial cell thickness (GECT), and Johnsen's mean testicular biopsy scoring (MTBS). The MSTD, GECT, and healthy sperms in the C group were significantly lower than the other groups, while the BM and LC groups were significantly different from others in MTBS. The number of sperms and sperm motility in the BM group was significantly higher than the C group. Sperm viability in the BM and LC groups were significantly higher than the C group. The results of this study showed that both L-carnitine and betamethasone similarly can be effective in treating testicular IR injuries.

Abstract
INTRODUCTION Surgical resection is the gold standard in treatment of hepatic malignancies, giving the patient the best chance to be cured. The liver has a unique capacity to regenerate. However, an inflammatory response occurs during resection, in part mediated by Kupffer cells, that influences the speed of regeneration. The aim of this study was to investigate the effect of a Kupffer cell targeted anti-inflammatory treatment on liver regeneration in rats. METHODS Two sets of animals, each including four groups of eight rats, were included. Paired groups from each set received treatment with placebo, low dose dexamethasone, high dose dexamethasone or low dose anti-CD163 dexamethasone. Subsequently, the rats underwent 70% partial hepatectomy. The two sets were evaluated on postoperative day 2 or 5, respectively. Blood was drawn for circulating markers of inflammation and liver cell damage; liver tissue was sampled for analysis of regeneration rate and proliferation index. RESULTS The high dose dexamethasone group had significantly lower body and liver weight than the placebo and anti-CD163-dex groups. There were no differences in liver regeneration rates between groups. Hepatocyte proliferation was completed faster in the placebo group, although this was not significant. The anti-CD163-dex group showed increased blood levels of albumin and alanine aminotransferase and a diminished inflammatory response in terms of significantly reduced haptoglobin, α2-macroglobulin and Interleukine-6. CONCLUSION Low dose dexamethasone targeted to Kupffer cells does not affect histological liver cell regeneration after 70% hepatectomy in rats, but reduces the inflammatory response judged by circulating markers of inflammation.

Abstract
Glucocorticoids are effective for the treatment of acute-on-chronic pre-liver failure, severe chronic hepatitis B and acute liver failure; however, the mechanism underlying the effects of treatment by glucocorticoids remains to be fully elucidated. The role and detailed mechanism of how glucocorticoids prevent liver disease progression can be elucidated by investigating the apoptosis of hepatocytes following glucocorticoid treatment. P‑glycoproteins (P‑gps) also confer resistance to apoptosis induced by a diverse range of stimuli. Glucocorticoids, particularly dexamethasone (DEX), upregulate the expression of P‑gp in several tissues. In the present study, the normal human L‑02 liver cell line was used, and techniques, including immunocytochemistry, western blot analysis, flow cytometry and reverse transcription‑quantitative polymerase chain reaction analysis were used for determining the expression levels of P‑gps, and for evaluating the effect of DEX pretreatment on the expression of P‑gps. DEX (1‑10 µM) was added to the cell culture media and incubated for 24‑72 h. The results revealed that DEX upregulated the mRNA and protein levels of P‑gp in a dose‑ and time‑dependent manner. Subsequently, tumor necrosis factor‑related apoptosis‑inducing ligand (TRAIL) was used for the induction of apoptosis in the cells, followed by a terminal deoxynucleotidyl transferase dUTP nick end labeling assay to assess the apoptotic stages. The results demonstrated that apoptosis in the group of cells, which were pre‑treated with DEX was significantly lower than that in the control group. Treatment with tariquidar, a P‑gp inhibitor, reduced the anti‑apoptotic effects of DEX. These results established that DEX protects normal human liver cells from TRAIL‑induced apoptosis by upregulating the expression of P-gp. These observations may be useful for elucidating the mechanism of DEX for preventing the progression of liver disease.

Abstract
Aim The Pringle maneuver is a way to reduce blood loss during liver surgery. However, this may result in ischemia/reperfusion injury in the development of which Kupffer cells play a central role. Corticosteroids are known to have anti-inflammatory effects. Our aim was to investigate whether a conjugate of dexamethasone and antibody against the CD163 macrophage cell surface receptor could reduce ischemia/reperfusion injury in the rat liver. Methods Thirty-six male Wistar rats were used for the experiments. Animals were randomly divided into four groups of eight receiving anti-CD163-dexamethasone, high dose dexamethasone, low dose dexamethasone or placebo intravenously 18 h before laparotomy with subsequent 60 min of liver ischemia. After reperfusion for 24 h the animals had their liver removed. Bloods were drawn 30 min and 24 h post ischemia induction. Liver cell apoptosis and necrosis were analyzed by stereological quantification. Results After 24 h' reperfusion, the fraction of cell in non-necrotic tissues exhibiting apoptotic profiles was significantly lower in the high dose dexamethasone (p = 0.03) and anti-CD163-dex (p = 0.03) groups compared with the low dose dexamethasone and placebo groups. There was no difference in necrotic cell volume between groups. After 30 min of reperfusion, levels of haptoglobin were significantly higher in the anti-CD163-dex and high dose dexamethasone groups. Alanine aminotransferase and alkaline phosphatase were significantly higher in the high dose dexamethasone group compared to controls after 24 h' reperfusion. Conclusions We show that pharmacological preconditioning with anti-CD163-dex and high dose dexamethasone reduces the number of apoptotic cells following ischemia/reperfusion injury. We investigated the effect of pharmacologic preconditioning with HDD, LDD and anti-CD163-dex on ischemia/reperfusion injury. Liver cell apoptosis and necrosis were analyzed by stereological quantification. Anti-CD163-dex and high dose dexamethasone reduces the number of apoptotic cells following ischemia/reperfusion injury.

Abstract
BACKGROUND Severe acute exacerbation of chronic hepatitis B can sometimes occur and lead to hepatic failure and death. The objective of this study was to elucidate the predictors of progression to hepatic decompensation during severe acute exacerbation. METHODS We prospectively analyzed 37 consecutive patients with acute exacerbation of chronic hepatitis B (accompanied by jaundice and coagulopathy) for clinical outcome and factors that influenced the development of severe acute exacerbation, including viral kinetics. RESULTS Fourteen (37.8%) patients progressed to severe acute exacerbation (accompanied by encephalopathy). Multivariate analysis identified serum bilirubin (>5 mg/dl, P = 0.002) as a significant determinant of progression to hepatic failure and prothrombin activity (<45%, P = 0.028) and as a determinant of liver-related death. The hepatitis B virus (HBV) DNA level before therapy was measured in 25 patients. HBV DNA levels increased or did not change from before commencement of treatment in all 11 patients who progressed to severe acute exacerbation. On the other hand, HBV DNA levels did not change or increased in 8 of 14 patients (57%) with acute exacerbation (P = 0.02). CONCLUSIONS Serum bilirubin and prothrombin activities were significant predictors of clinical outcome in patients with severe acute exacerbation of chronic hepatitis B. Viral kinetics until commencement of therapy can predict the severity of acute exacerbation of chronic hepatitis B.

Abstract
AIM Acute-on-chronic pre-liver failure (pre-ACLF) is defined as a severe acute episode of chronic hepatitis B characterized by serum bilirubin of 171 µmol/L or more, alanine aminotransferase of five times or more the upper limit of normal and prothrombin activity of more than 40%, having a potential for progression to acute-on-chronic liver failure (ACLF). This study is to evaluate the efficacy of short-term dexamethasone in pre-ACLF. METHODS One hundred and seventy patients were assigned to dexamethasone therapy and control group at a ratio of 1:2. For the two groups, we compared biochemical indicators, the incidence of ACLF and mortality. The influential factors on the mortality of patients with pre-ACLF were studied by Cox proportional hazards models. RESULTS The significantly lower incidence of ACLF and higher survival rate were observed in patients on dexamethasone therapy (8.9%, 96.4%, respectively) than in control patients (70.2%, 52.6%, respectively; P < 0.001). Dexamethasone treatment was an independent factor influencing the survival rate (P < 0.001, odds ratio = 0.055, 95% confidence interval = 0.013-0.225). During 4 weeks of treatment, serum bilirubin levels of survival patients were significantly lower in the dexamethasone group than control group. CONCLUSION Five-day dexamethasone therapy is effective in improving the liver function and survival rate of patients with pre-ACLF.

Respir Res 2010; 11:178.

Abstract
BACKGROUND High dose of corticosteroids has been previously shown to protect against controlled mechanical ventilation (CMV)-induced diaphragmatic dysfunction while inhibiting calpain activation. Because literature suggests that the calpain inhibiting effect of corticosteroid depends on the dose administered, we determined whether lower doses of corticosteroids would also provide protection of the diaphragm during CMV. This may be important for patients undergoing mechanical ventilation and receiving corticosteroids. METHODS Rats were assigned to controls or to 24 hours of CMV while being treated at the start of mechanical ventilation with a single intramuscular administration of either saline, or 5 mg/kg (low MP) or 30 mg/kg (high MP) of methylprednisolone. RESULTS Diaphragmatic force was decreased after CMV and this was exacerbated in the low MP group while high MP rescued this diaphragmatic dysfunction. Atrophy was more severe in the low MP group than after CMV while no atrophy was observed in the high MP group. A significant and similar increase in calpain activity was observed in both the low MP and CMV groups whereas the high dose prevented calpain activation. Expression of calpastatin, the endogenous inhibitor of calpain, was decreased in the CMV and low MP groups but its level was preserved to controls in the high MP group. Caspase-3 activity increased in all CMV groups but to a lesser extent in the low and high MP groups. The 20S proteasome activity was increased in CMV only. CONCLUSIONS Administration of 30 mg/kg methylprednisolone during CMV protected against CMV-induced diaphragm dysfunction while 5 mg/kg was more deleterious. The protective effect is due mainly to an inhibition of the calpain system through preservation of calpastatin levels and to a lesser extent to a caspase-3 inhibition.

Protective effect of methylprednisolone on warm ischemia-reperfusion injury in a cholestatic rat liver. Am J Surg 2010; 199:377-80; discussion 380-1.

Abstract
BACKGROUND Cholestasis has been identified as a risk factor for oxidative stress, and it potentially enhances after ischemic-reperfusion injury. The aim of this study was to evaluate the role of methylprednisolone on warm ischemia-reperfusion injury in the presence of cholestasis. METHODS A reversible cholestatic rat model was created. After 7 days, rats received 30 mg/kg of intravenous methylprednisolone 2 hours before ischemia, followed by 30 minutes of ischemia. Rats were euthanized 24 hours after ischemia. Serum aspartate aminotransferase and interleukin-6 were measured, and the liver was harvested for histology and myeloperoxidase estimation. RESULTS Methylprednisolone had a protective effect, with a statistically significant decrease in aspartate aminotransferase (P=.01) and a trend toward decreased levels of interleukin-6 (P=.07). Histology showed a significant difference in architectural distortion (P=.01), cytoplasmic vacuolation (P=.01), and nodular hepatocellular necrosis (P=.04). CONCLUSIONS Methylprednisolone attenuated the ischemic-reperfusion injury in the presence of cholestasis and can be considered for clinical use in the presence of cholestasis.
