Pediatric acute liver failure (PALF) is a rare and critical clinical syndrome with a poor prognosis. Its etiology is complex, with a significant proportion of cases having remained classified as indeterminate or cryptogenic PALF. With the application of high-throughput sequencing technologies, a spectrum of disorders caused by specific genetic metabolic defects and characterized by stress-sensitive Recurrent acute liver failure (RALF) has been gradually unveiled, collectively termed Infantile liver failure syndrome (ILFS). Although the molecular mechanisms underlying the subtypes ILFS1, ILFS2, and ILFS3 differ by involving aminoacyl-tRNA synthetase defects, vesicular transport disorders, and autophagy abnormalities, respectively, they share a common clinical phenotype of RALF triggered by fever or infection. This article has systematically reviewed the clinical phenotypic spectrum, molecular genetic characteristics, differential diagnosis strategies, and therapeutic advances of the three ILFS subtypes, with the goal of improving early clinical recognition and precise intervention, and providing an important reference for evaluating the prognosis of different subtypes.

BACKGROUND

Tuberculosis (TB) has long been a recognized infectious disease contributory to worldwide mortalities. Most cases are from low- to middle-income countries, including the Philippines. Hepatobiliary TB comprises only a small portion of extrapulmonary TB. Tuberculous liver abscess (TLA) usually presents with nonspecific findings causing delay in the diagnosis. Due to this, further reports are needed for early detection along with timely treatment for future courses.

Presenting a 17-year-old male who came in with right upper quadrant abdominal pain associated with intermittent fever. The symptoms persisted and eventually progressed to abdominal distention, weight loss and jaundice. Initial laboratories were taken including an ultrasound finding of a complex lesion in the hepatic lobe. He was initially managed with empiric antibiotic therapy – Ciprofloxacin and Metronidazole, however, despite it, there was persistence of right upper quadrant pain, abdominal distention and jaundice. Due to this, further work-up was done with drainage of the abscess. Cultures were taken revealing tubercle bacilli along with other microbial growth. Antibiotics and antituberculosis medications sensitive to the microorganisms were started. With the noted improvement of jaundice and abdominal distention and resolution of pain and fever, he was discharged.

 Tuberculous liver abscess is an uncommon presentation of extrapulmonary tuberculosis in an
immunocompetent male with right upper quadrant abdominal pain and jaundice. Although TB is endemic in the
Philippines, this gastrointestinal involvement is often not immediately recognized. Thus, with any suspicion of liver abscess,
tuberculous (TLA) type should be included in the differentials for early diagnosis and management. 

BACKGROUND

Sarcopenia is highly prevalent in patients with liver cirrhosis and contributes to decreased quality of life, increased morbidity, and mortality. The role of myostatin in cirrhosis-related sarcopenia remains controversial but may represent a potential therapeutic target.

This study aimed to investigate the association between serum myostatin levels and sarcopenia in patients with liver cirrhosis.

A cross-sectional study was conducted with 80 patients diagnosed with liver cirrhosis at Prof. Dr. I.G.N.G. Ngoerah General Hospital, Denpasar, Bali, Indonesia. Serum myostatin levels (ng/L) were measured using an ELISA technique. Sarcopenia was diagnosed based on the 2019 Asian Working Group for Sarcopenia (AWGS) consensus. Elevated myostatin levels were defined as values above the median. Bivariate and multivariate analyses were performed to assess associations between myostatin, cirrhosis severity, and sarcopenia.

The severity of cirrhosis (CTP B and C) was associated with elevated myostatin levels (PR = 2.046; 95% CI: 1.310–3.193; p = 0.002). Bivariate analysis demonstrated that elevated myostatin (PR = 2.178; 95% CI: 1.370–3.461; p < 0.001), CTP B and C (PR = 1.818; 95% CI: 1.223–2.701; p = 0.004), ascites (PR = 1.606; 95% CI: 1.110–2.324; p = 0.034), and malnutrition (PR = 1.806; 95% CI: 1.242–2.626; p = 0.004) were associated with sarcopenia. In multivariate analysis, only elevated serum myostatin remained significantly associated with sarcopenia (AOR = 4.273; 95% CI: 1.557–11.724; p = 0.005).

Elevated serum myostatin levels are strongly associated with sarcopenia in patients with liver cirrhosis. Cirrhosis severity is also linked to higher myostatin levels, suggesting a potential role for myostatin-targeted interventions in sarcopenia management.

Introduction: Metabolic dysfunction–associated steatotic liver disease (MASLD) is common among patients with type 2 diabetes (T2D) and increases the risk of cirrhosis, yet fibrosis often remains clinically silent until hepatic decompensation occurs. Current diabetes guidelines recommend noninvasive fibrosis risk stratification, such as the fibrosis-4 index (FIB-4), during routine diabetes care, but real-world adoption remains unclear. This study aimed to evaluate the implementation of FIB-4 as a risk stratification tool in patients with T2D. Methodology: This was a retrospective study of consecutive patients with T2D who were seen in the Diabetes Clinic of University of Malaya Medical Centre in 2023. Patients were identified as having a higher risk of future cirrhosis based on elevated FIB-4 ≥1.3. Results: The data for 1,009 patients were analyzed, median age 62 (52–71) years, 40.7% male. Elevated FIB-4 was seen in 28.8% (291/1,009). Only 12.0% (35/291) with elevated FIB-4 were referred for further hepatology evaluation, whereas 3.3% (24/718) with low FIB-4 were referred. Among the patients with elevated FIB-4, those referred were more likely known to have hepatic steatosis, had higher alanine aminotransferase, aspartate aminotransferase, gammaglutamyl transferase, and lower low-density lipoprotein cholesterol and platelet count. Over a median follow-up of 1.71 (0.99–1.95) years, totaling 1,440 person-years, two liverrelated events (0.2%) occurred (one each in the elevated and low FIB-4 group, respectively). Sixteen patients (4.0%) experienced cardiovascular events, including one patient (0.6%) in the elevated FIB-4 group and 15 (2.9%) in the low FIB-4 group. Conclusion Despite automated FIB-4 reporting, this risk stratification tool was underutilized in T2D, resulting in missed opportunities for early identification and management of more severe liver disease. Integration of FIB-4 into diabetes care workflows, alongside structured referral pathways and clinician education, may improve early detection and reduce long-term hepatic complications in T2D.

Introduction: The global rise in paediatric obesity has led to an increasing burden of metabolic comorbidities, including metabolic dysfunction–associated steatotic liver disease (MASLD). Obstructive sleep apnea (OSA), characterized by chronic intermittent hypoxia, has been implicated in the pathogenesis of liver injury. This study aimed to evaluate the prevalence of MASLD and its association with OSA among children and adolescents in a tertiary centre. Methodology: A retrospective cross-sectional study was conducted involving children aged 6–15 years who were admitted for polysomnography at Sarawak General Hospital between 2024 and 2025. Clinical, biochemical, and lifestyle data were obtained from medical records and parental questionnaires. Hepatic steatosis was assessed using hepatobiliary ultrasound in a subset of patients. Results: A total of 132 children (mean age 10.8 ± 2.7 years; 87.5% male) were included. The median BMI SDS was 2.50 (IQR: 2.29– 2.93). The mean apnea–hypopnea index (AHI) was 12.0 ± 7.9, with 60% classified as severe OSA. Among the 16 children who underwent liver ultrasound, MASLD was identified in 81.2%, including five cases of grade 1 and eight cases of grade 2 steatosis. Liver transaminitis was present in six patients. Metabolic comorbidities were common, with 43.8% requiring metformin for insulin resistance or impaired glucose tolerance, and four patients requiring antihypertensive therapy. Unhealthy lifestyle behaviors were prevalent: 64.2% consumed sugary drinks ≥3 times weekly, 42.9% consumed fast food ≥3 times weekly, and only 24.3% reported daily fruit or vegetable intake. Physical inactivity (≤2 times/week) was observed in 71.4%, while 64.3% had screen time exceeding 2 hours daily. Conclusion Children and adolescents with moderate-to-severe OSA exhibit a high burden of metabolic dysfunction, including MASLD. The findings support a potential contributory role of OSA-related hypoxia in paediatric fatty liver disease and highlight the need for integrated screening and early intervention in this high-risk population.

Alcoholic liver disease(ALD), a major cause of chronic liver disease worldwide, poses a serious threat to human health. Despite the availability of various drugs for treating ALD, their efficacy is often uncertain, necessitating the search for new therapeutic approaches. Traditional Chinese medicine polysaccharides have garnered increasing attention in recent years due to their versatility, high efficiency, and low side effects, and they have demonstrated significant potential in preventing and treating ALD. Emerging studies have suggested that these polysaccharides exert their therapeutic effects through multiple mechanisms, including the inhibition of oxidative stress and the regulation of lipid metabolism, gut microbiota, and programmed cell death. This review summarizes the recent research progress in the pharmacological effects and regulatory mechanisms of traditional Chinese medicine polysaccharides in treating ALD, aiming to provide a scientific basis and theoretical support for their application in the prevention and treatment of ALD.

This study aims to explore the mechanism of Huanglian Jiedu Decoction(HJD) in treating acute liver injury(ALI) in the mouse model of sepsis induced by lipopolysaccharide(LPS). Fifty-four male C57BL/6 mice were randomized into six groups: blank group, model group, low-, medium-, and high-dose group HJD, and dexamethasone group. The mouse model of sepsis was established by intraperitoneal injection of LPS after 7 days of gavage with HJD, and dexamethasone(0.2 mL) was injected intraperitoneally 1.5 h after modeling. The murine sepsis score(MSS) was recorded 12 h after modeling. The levels of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) in the liver tissue and tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) in the serum were measured by ELISA. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of the mouse liver. The content of light chain 3 of microtubule-associated protein 1(LC3) was detected by immunofluorescence, and that of sirtuin 1(SIRT1) was detected by immunohistochemistry. The mRNA levels of adenosine 5'-monophosphate-activated protein kinase(AMPK), LC3, and P62 were detected by RT-PCR. Western blot was employed to determine the protein levels of AMPK, p-AMPK, and SIRT1 in the liver tissue. The results showed that compared with model group, drug interventions decreased the MSS and liver injury indicators, lowered the levels of inflammatory cytokines, improved the liver tissue structure, upregulated the protein levels of of p-AMPK/AMPK and SIRT1 and the mRNA levels of AMPK and LC3, and downregulated the mRNA level of P62. To sum up, HJD can regulate the autophagy level and reduce inflammation to ameliorate acute liver injury in septic mice by activating the AMPK/SIRT1 autophagy pathway.

To explore the anti-depression effect of Suanzaoren Decoction(SZRD), the regulatory effects on endogenous metabolites in the liver of rats with depression induced by chronic unpredictable mild stress(CUMS) were analyzed by using LC-MS metabolomics. The rats were randomly divided into normal control group, model group, low-dose SZRD group, high-dose SZRD group, and positive drug group. The CUMS depression model was replicated by applying a variety of stimuli, such as fasting and water deprivation, ice water swimming, hot water swimming, day and night reversal, tail clamping, and restraint for rats. Modeling and treatment were conducted for 56 days. The behavioral indexes of rats in each group, including body weight, open field test, sucrose preference test, and tail suspension test, were observed. Plasma samples and liver tissue samples were collected, and the contents of 5-hydroxytryptamine(5-HT), dopamine(DA), and norepinephrine(NE) in plasma were measured using enzyme-linked immunosorbent assay(ELISA). Meanwhile, the regulatory effects of SZRD on the liver metabolic profile of CUMS model rats were analyzed by the LC-MS metabolomics method. The results show that SZRD can significantly improve the depression-like behavior of CUMS model rats and increase the neurotransmitter levels of 5-HT, DA, and NE in plasma. A total of 24 different metabolites in the rats' liver are identified using the LC-MS metabolomics method, and SZRD can reverse 13 of these metabolites. Metabolic pathway analysis indicates that nine metabolic pathways are found to be significantly associated with depression, and in the low-dose SZRD group, four pathways can be regulated, including pentose phosphate pathway, purine metabolism, inositol phosphate metabolism, and sphingolipid metabolism. In the high-dose SZRD group, two metabolic pathways can be regulated, including sphingolipid metabolism and glycerol glycerophospholipid metabolism. Sphingolipid metabolism is a metabolic pathway that can be regulated by SZRD at different doses, so it is speculated that it may be the primary pathway through which SZRD can alleviate metabolic disturbances in the liver of CUMS model rats.

Anxiety disorder is a highly prevalent psychological illness, and research has shown that obesity is a significant risk factor for its development. This study explored the ameliorative effects and mechanisms of saponins from Panax japonicus(SPJ) on anxiety disorder in mice fed a high-fat diet(HFD). Fifty C57BL/6J mice were randomly divided into normal control diet(NCD) group, HFD group, and low-and high-dose SPJ groups. At week 12, six mice from the HFD group were further divided into a control group(treated with DMSO) and an exogenous fibroblast growth factor 21(FGF21) group(administered rFGF21). The anxiety-like behavior of the mice was assessed using the open field test and elevated plus maze test. Hematoxylin-eosin(HE) staining and oil red O staining were performed to observe pathological changes in the liver and adipose tissue. Glucose metabolism was evaluated through the glucose tolerance test(GTT) and insulin tolerance test(ITT). Western blot analysis was performed to detect the expression of FGF21 and its downstream-related proteins in the liver and cortex, along with the expression of brain-derived neurotrophic factor(BDNF), disks large homolog 4(DLG4), and synaptophysin(SYP) in the cortex. Real-time quantitative fluorescent PCR(qPCR) was used to detect the expression of FGF21 and its receptor genes in the liver and cortex. Immunofluorescence staining was employed to examine the expression of neuronal activator c-Fos, FGF21, and the FGF21 co-receptor β-klotho in the cerebral cortex. The results showed that SPJ significantly improved the frequency of activity in the open arms of the elevated plus maze and the central area of the open field in HFD mice, up-regulated the expression of BDNF, DLG4, and SYP, and effectively alleviated anxiety-like behaviors in HFD mice. Compared with the NCD group, HFD mice exhibited up-regulated expression of FGF21 in the liver and cerebral cortex, while the expression of fibroblast growth factor receptor 1(FGFR1) and β-klotho was significantly down-regulated, suggesting that HFD mice exhibited FGF21 resistance. SPJ markedly up-regulated the β-klotho levels in HFD mice, reversing FGF21 resistance. Further comparison with exogenously administered FGF21 revealed that SPJ activates brain cortical regions in a consistent manner, and additionally, SPJ promotes the number and colocalization of c-Fos and β-klotho positive cells in the brain cortex. In summary, SPJ effectively alleviates anxiety-like behaviors in HFD mice. Its mechanism is associated with up-regulation of β-klotho expression in the brain, reversal of FGF21 resistance, and subsequent activation of neurons in the cerebral cortex and amygdala.

Based on the similarity of chemical constituents between Panax notoginseng flowers and rhizomes, this study investigated their lipid-lowering effects and impacts on the intestinal flora of rats. The main components of P. notoginseng flowers and rhizomes were detected by ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF-MS) to compare their chemical similarities. A hyperlipidemia rat model was induced using a high-fat diet. After successful modeling, the rats were divided into the blank control group, blank administration group(0.090 g·kg~(-1)), model group, low-(0.045 g·kg~(-1)), medium-(0.090 g·kg~(-1)), high-dose(0.180 g·kg~(-1)) P. notoginseng flower group, P. notoginseng rhizome group(0.270 g·kg~(-1)), and simvastatin group(0.900 mg·kg~(-1)). After modeling, the rats were given intragastric administration for 3 weeks, once daily, while their body weight was recorded regularly. Before the last administration, fresh feces were collected for analysis of changes in intestinal flora using 16S rDNA high-throughput sequencing technology. One hour after the last administration, the rats were anesthetized with 1% pentobarbital sodium, and blood was collected from the abdominal aorta. Serum biochemical indexes were detected using an automatic biochemical analyzer. Organs(heart, liver, spleen, lung, and kidney) were harvested, and organ index were calculated. Liver tissue pathology was assessed through HE staining and oil red O staining. The results indicated that there were 33 identical chemical constituents in P. notoginseng flowers and rhizomes, accounting for 75.00% of the total constituents. After treatment, high-dose P. notoginseng flower group and P. notoginseng rhizome group exhibited similar effects on body weight, serum biochemical indexes, and liver histopathological conditions. Compared with model control group, the abundance of Firmicutes and Actinobacteria increased in high-dose P. notoginseng flower and rhizome groups, while the abundance of Bacteroidetes and Thermodesulfobacteria decreased. Cluster analysis showed no significant difference between the two groups. Both P. notoginseng flowers and rhizomes possess similar chemical components and lipid-lowering effects, and they can regulate the intestinal flora imbalance caused by hyperlipidemia, indicating their potential for use in hyperlipidemia treatment.
