Circulating metabolites are associated with persistent elevations of ALT in patients with chronic hepatitis B with complete viral suppression. J Med Virol 2024; 96:e29723. [PMID: 38828911 DOI: 10.1002/jmv.29723] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 05/05/2024] [Accepted: 05/23/2024] [Indexed: 06/05/2024]
Abstract
Hepatitis B virus (HBV) can be completely suppressed after antiviral treatment; however, some patients with chronic hepatitis B (CHB) exhibit elevated alanine aminotransferase (ALT) levels and sustained disease progression. This study provides novel insights into the mechanism and potential predictive biomarkers of persistently elevated ALT (PeALT) in patients with CHB after complete viral inhibition. Patients having CHB with undetectable HBV DNA at least 12 months after antiviral treatment were enrolled from a prospective, observational cohort. Patients with PeALT and persistently normal ALT (PnALT) were matched 1:1 using propensity score matching. Correlations between plasma metabolites and the risk of elevated ALT were examined using multivariate logistic regression. A mouse model of carbon tetrachloride-induced liver injury was established to validate the effect of key differential metabolites on liver injury. Of the 1238 patients with CHB who achieved complete viral suppression, 40 (3.23%) had PeALT levels during follow-up (median follow-up: 2.42 years). Additionally, 40 patients with PnALT levels were matched as controls. Ser-Phe-Ala, Lys-Ala-Leu-Glu, 3-methylhippuric acid, 3-methylxanthine, and 7-methylxanthine were identified as critical differential metabolites between the two groups and independently associated with PeALT risk. Ser-Phe-Ala and Lys-Ala-Leu-Glu levels could be used to discriminate patients with PeALT from those with PnALT. Furthermore, N-acetyl- l-methionine (NALM) demonstrated the strongest negative correlation with ALT levels. NALM supplementation alleviated liver injury and hepatic necrosis induced by carbon tetrachloride in mice. Changes in circulating metabolites may contribute to PeALT levels in patients with CHB who have achieved complete viral suppression after antiviral treatment.

Abstract
We investigated the mechanism of action of panaxynol (PAL) extract from the root of Saposhnikovia diviaricata (Turcz.) Schischk for treating acute liver injury caused by lipopolysaccharide (LPS) and D-galactosamine (D-Gal N) in mice. A mouse model of acute liver failure induced by LPS/D-Gal N was established. Mice were divided randomly into three equal groups: control group, LPS/D-Gal N group and PAL group. After seven days of continuous PAL administration, all animals except controls were injected with 50 μg/kg LPS and 800 mg/kg D-Gal N; blood and liver samples were collected after 8 h. Compared to the LPS/D-Gal N group, the levels of catalase, glutathione and superoxide dismutase were increased in the liver of the PAL group. The inflammatory response index indicated that PAL attenuated LPS/D Gal N-induced liver pathological injury and decreased levels of hepatic malondialdehyde, serum alanine aminotransferase, aspartate transaminase, tumor necrosis factor-α, and interleukins 1β and 6. PAL also inhibited LPS/D-Gal N induced nuclear factor-kappa B (Nf-κB), inhibitor kappa B-α (IκB-α) activation, and up-regulated Nrf2 and heme oxygenase-1 (HO-1) expression. PAL can prevent LPS/D-Gal N induced acute liver injury by activating Nrf2/HO-1 to stimulate antioxidant defense and inhibit the IkB-α/NF-κB signaling pathway.

Abstract
Radiation pneumonitis is a clinical problem with a high incidence. Once the onset of radiation pneumonitis has occurred, the administration of antioxidants and anti-inflammatory agents is the most commonly used method of clinical treatment. Quercetin (Que) is a common flavonoid, with potent anti-inflammatory and anti-oxidant activities. In the present study, the therapeutic effect of inhaled Que on radiation-induced radiation pneumonitis in rats was investigated. Treatment with Que via inhalation was shown to increase the number of leukocytes and erythrocytes in the blood, and reduce the number of inflammatory cells in bronchoalveolar lavage fluid. Histological examination of lung tissue indicated that inhaled Que reduced hemorrhaging and the infiltration of inflammatory cells, and suppressed the expression of the proinflammatory cytokines transforming growth factor-β1 and interleukin-6. These results indicated that treatment with Que via inhalation ameliorates radiation pneumonitis by reducing the number of inflammatory cells, and attenuating the inflammatory response and pathological changes. This suggests that administration of Que via inhalation has the potential to become a novel treatment for radiation pneumonitis.

Hepatoprotective effect of quercetin against LPS/d-GalN induced acute liver injury in mice by inhibiting the IKK/NF-κB and MAPK signal pathways. Int Immunopharmacol 2017; 52:281-289.

Abstract
Quercetin is regarded as a potential hepatoprotective agent in the treatment of acute liver injury. However, the underlying mechanism of how quercetin to protect against lipopolysaccharides/d-galactosamine (LPS/d-GalN) induced acute liver injury remains unclear. To investigate the mechanism, the antioxidative, anti-inflammatory and antiapoptotic responses were performed. The results showed that quercetin pretreatment improved the survival rate and substantially reduced the liver histopathological changes in mice. It also alleviated the hepatic damage and reduced the productions of oxidative markers induced by LPS/d-GalN. In addition, quercetin pretreatment significantly diminished the production of inflammatory cytokines, including TNF-α, IL-6 and IL-1β, and inhibited the activation of the NF-κB and MAPK signaling pathways as well as the expression of apoptotic-related proteins induced by LPS/d-GalN. We found that the potential mechanism of this quercetin-induced protection is mainly mediated through its powerful antioxidative capacity, inhibition of hepatocyte apoptosis and suppression of inflammatory cytokines through the IKK/NF-κB and MAPK signaling pathways. Thus, quercetin shows a promising therapeutic effect on acute liver injury in mice.

Abstract
Immune response plays an important role in the development of hepatic fibrosis. In
the present study, we investigated the effects of quercetin on hepatitis and hepatic
fibrosis induced by immunological mechanism. In the acute hepatitis model, quercetin
(2.5 mg/kg) was injected iv into mice 30 min after concanavalin A
(Con A) challenge. Mice were sacrificed 4 or 24 h after Con A injection, and
aminotransferase tests and histopathological sections were performed. Treatment with
quercetin significantly decreased the levels of alanine aminotransferase (ALT) and
aspartate aminotransferase (AST). Consistent with this observation, treatment with
quercetin markedly attenuated the pathologic changes in the liver. A hepatic fibrosis
model was also generated in mice by Con A challenge once a week for 6 consecutive
weeks. Mice in the experimental group were treated with daily iv
injections of quercetin (0.5 mg/kg). Histopathological analyses revealed that
treatment with quercetin markedly decreased collagen deposition, pseudolobuli
development, and hepatic stellate cells activation. We also examined the effects of
quercetin on the nuclear factor kappa-light-chain-enhancer of activated B cells
(NF-κB) and transforming growth factor beta (TGF-β) pathways by immunohistochemistry
and real-time reverse transcriptase-polymerase chain reaction (RT-PCR). NF-κB and
TGF-β production was decreased after treatment with quercetin, indicating that the
antifibrotic effect of quercetin is associated with its ability to modulate NF-κB and
TGF-β production. These results suggest that quercetin may be an effective
therapeutic strategy in the treatment of patients with liver damage and fibrosis.

Abstract
OBJECTIVE To investigate the protective effect of quercetin (QE), an anti-inflammatory and anti-oxidant agent, on torsion-detorsion induced histopathological changes and blood IMA levels in experimental ovarian ischemia-reperfusion (IR) injury. STUDY DESIGN Twenty-four female Wistar rats were randomly divided into four groups in this study (n=6). Group I, (sham operation); Group II, torsion-detorsion plus saline (IR); Group III, torsion-detorsion plus solvent (dimethylsulfoxide: DMSO, IR+DMSO); Group IV, torsion-detorsion plus 15 mg/kg/bw quercetin (IR+QE) injected intraperitoneally 30 min prior to detorsion. After 3h of reperfusion, the right ovaries were removed surgically. The ovary tissue samples were fixed in 10% formalin solution for histopathological and immunohistochemical examination. Blood samples were obtained at the end of the procedures for each group of animals. RESULTS Ovarian sections in Groups II and III showed higher follicular cell degeneration, hemorrhage, vascular congestion and edema when compared with Group I. Administration of quercetin in rats significantly prevented degenerative changes in the ovary. Significantly less histopathological changes were found in Group IV compared with Groups II and III. Caspase-3 and TUNEL positive cells were detected in the ovarian surface, follicle epithelium, and stromal cells in all experimental groups, and there was a significant increase in Groups II and III compared with Group I (P<0.05). Treatment with quercetin decreased the number of caspase-3 and TUNEL positive cells. IR increased the ischemia modified albumin (IMA) levels in comparison to the sham group (1.06 ± 0.10 ABSU and 0.92 ± 0.08 ABSU, P<0.05). Quercetin administration before IR reduced the levels of IMA (0.93 ± 0.08 ABSU, P<0.05). CONCLUSION Administration of quercetin is effective in preventing tissue damage induced by IR injury in ovaries.

Abstract
The present study was carried out to evaluate the neuroprotective effect of quercetin (QE) in protecting the cadmium (Cd)-induced neuronal injury in frontal cortex of rats. A total of 30 adult male Sprague-Dawley rats were randomly divided into three groups of 10 animals each: control, Cd treated and Cd treated with QE. The Cd-treated group was injected subcutaneously with cadmium chloride (CdCl2) dissolved in saline at a dose of 2 ml/kg/day for 30 days, resulting in a dosage of 1 mg/kg Cd. The rats in QE-treated groups were given QE (15 mg/kg body weight) once a day intraperitoneally starting 2 days prior to Cd injection, during the study period. Rats were sacrificed at the end of the study and the frontal cortex tissues were removed for biochemical and histopathological investigation. To date, there is no available information on the effect of QE on neuronal injury after Cd exposure. Rats intoxicated with Cd for 30 days, significantly increased tissue malondialdehyde (MDA) levels and significantly decreased enzymatic antioxidants superoxide dismutase, glutathione peroxidase and catalase in the frontal cortex tissue. Administration of QE with Cd significantly diminished the levels of MDA and significantly elevated the levels of enzymatic antioxidants in the frontal cortex tissue. The histopathological studies in the brain of rats also supported that QE markedly reduced the Cd-induced histopathological changes and well preserved the normal histological architecture of the frontal cortex tissue. The caspase-3 immunopositivity was increased in degenerating neurons of the Cd group. Treatment with QE markedly reduced the immunoreactivity of degenerating neurons. In conclusion, the results of the current study suggest that QE may be beneficial in combating the Cd-induced neurotoxicity in the brain of rats. We believe that further preclinical research into the utility of QE may indicate its usefulness as a potential treatment for neurodegeneration after Cd exposure in rats.
