ABSTRACT

La albúmina sérica humana es la proteína más abundante en el plasma, su estructura molecular le confiere estabilidad, pero también flexibilidad para ligar y transportar un amplio rango de moléculas. Su función oncótica es la propiedad más reconocida que la lleva a introducirse en la terapéutica médica como un expansor de volumen. Sin embargo, en los últimos años se le han adicionado funciones con carácter antioxidante, inmunomodulador y de estabilización endotelial, que hacen presumir que su impacto terapéutico está más allá de sus funciones volumétricas. En los últimos años, específicamente en la cirrosis y la falla hepática aguda sobre crónica, se ha tenido un cambio en el paradigma fisiológico, desde una perspectiva netamente hemodinámica hacia una perspectiva inflamatoria, en donde las funciones oncóticas y no oncóticas de la albúmina están alteradas y tienen un carácter pronóstico en estas entidades. Este conocimiento creciente, desde una perspectiva inflamatoria, hace que se fortalezca el uso terapéutico de la albúmina sérica humana desde las indicaciones tradicionales como prevención de la disfunción circulatoria posparacentesis, prevención y tratamiento de lesión renal aguda, hasta las discusiones para administración a largo plazo en pacientes cirróticos con ascitis.


Human serum albumin is the most abundant protein in plasma, with a molecular structure that provides stability while also allowing flexibility to bind and transport a wide range of molecules. Its oncotic function is the most recognized property, leading to its introduction in medical therapy as a volume expander. However, in recent years, additional functions with antioxidant, immunomodulatory, and endothelial stabilization properties have been identified, suggesting that its therapeutic impact extends beyond its volumetric functions. Specifically, in cirrhosis and acute-on-chronic liver failure, there has been a shift in the pathophysiological paradigm from a purely hemodynamic perspective to an inflammatory perspective, where both oncotic and non-oncotic functions of albumin are altered and have prognostic significance in these conditions. This growing understanding from an inflammatory perspective strengthens the therapeutic use of human serum albumin, not only for traditional indications such as the prevention of post-paracentesis circulatory disfunction, prevention and treatment of acute kidney injury, but also for discussions regarding long-term administration in cirrhotic patients with ascites.

ABSTRACT

Liver failure often has rapid progression, multiple complications, and dangerous conditions. Acute pancreatitis is a common comorbidity during the progression of liver failure, and since acute pancreatitis has extremely similar clinical symptoms and signs to liver failure complicated by spontaneous peritonitis, it is often neglected in clinical practice. This article elaborates on the mechanisms of liver failure complicated by acute pancreatitis from the five aspects of inflammatory response, duodenal papillary dysfunction, gut microbiota dysbiosis, oxidative stress, and microcirculatory disturbance and proposes corresponding preventive measures based on these mechanisms.

ABSTRACT

ObjectiveTo investigate the clinical features of patients with acute-on-chronic liver failure (ACLF) and bacterial infection and early warning indicators associated with multidrug-resistant infections. MethodsA retrospective analysis was performed for 130 patients with ACLF and bacterial infection who attended The Second Affiliated Hospital of Air Force Medical University from January 1, 2010 to December 31, 2021, and according to the drug susceptibility results, the patients were divided into multidrug-resistant (MDR) bacterial infection group with 80 patients and non-MDR bacterial infection group with 50 patients. General information and laboratory examination results were compared between the two groups to screen for the early warning indicators associated with MDR bacterial infection. The Student’s t-test was used for comparison of normally distributed continuous data with homogeneity of variance between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data or continuous data with heterogeneity of variance between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The binary logistic regression analysis and the receiver operating characteristic (ROC) curve were used to assess the predictive value of early warning indicators. ResultsAmong the 130 patients with ACLF and bacterial infection, sputum (27.7%) was the most common specimen for detection, followed by blood (24.6%), urine (18.5%), and ascites (17.7%). Bacterial infections were dominated by Gram-negative bacteria (58.5%). Of all bacteria, Escherichia coli (18.5%), Klebsiella pneumoniae (14.6%), and Enterococcus faecium (13.8%) were the most common pathogens. Gram-positive bacteria had a high resistance rate to the antibacterial drugs such as erythromycin (72.2%), penicillin (57.4%), ampicillin (55.6%), and ciprofloxacin (53.7%), while Gram-negative bacteria had a high resistance rate to the antibacterial drugs such as ampicillin (73.3%), cefazolin (50.0%), and cefepime (47.4%). The patients with ACLF and bacterial infection had a relatively high rate of MDR bacterial infection (61.5%). Comparison of clinical data between the two groups showed that compared with the patients with non-MDR bacterial infection, the patients with MDR bacterial infection had significantly higher levels of alanine aminotransferase (Z=2.089, P=0.037), aspartate aminotransferase (Z=2.063, P=0.039), white blood cell count (Z=2.207, P=0.027), and monocyte count (Z=4.413, P<0.001). The binary logistic regression analysis showed that monocyte count was an independent risk factor for MDR bacterial infection (odds ratio=7.120, 95% confidence interval [CI]: 2.478‍ ‍—‍ ‍20.456,P<0.001) and had an area under the ROC curve of 0.686 (95%CI: 0.597‍ ‍—‍ ‍0.776) in predicting ACLF with MDR bacterial infection(P<0.001), with the optimal cut-off value of 0.50×109/L, a sensitivity of 0.725, and a specificity of 0.400. ConclusionACLF combined with bacterial infections is mainly caused by Gram-negative bacteria, with the common pathogens of Escherichia coli and Klebsiella pneumoniae and a relatively high MDR rate in clinical practice. An increase in monocyte count can be used as an early warning indicator to distinguish MDR bacterial infection from non-MDR bacterial infection.

ABSTRACT

ObjectiveTo investigate the clinical efficacy of double plasma molecular adsorption system (DPMAS) and sequential plasma exchange (PE) combined with continuous renal replacement therapy (CRRT) in the treatment of patients with acute-on-chronic liver failure (ACLF) and acute kidney injury (AKI). MethodsA retrospective analysis was performed for the clinical data of 90 patients with ACLF and AKI who were hospitalized in The Affiliated Hospital of Guizhou Medical University from January 2019 to December 2022, and according to the method for blood purification, they were divided into DPMAS sequential PE+CRRT group (observation group with 31 patients) and DPMAS sequential PE group (control group with 59 patients). General data on admission and laboratory markers before and after blood purification were collected from all patients, including hepatic and renal function, coagulation function, and inflammation markers, and estimated glomerular filtration rate (eGFR) and MELD combined with serum sodium concentration (MELD-Na) score were calculated. The independent-samples t test was used for comparison of normally distributed continuous data between two groups; the Wilcoxon rank sum test was used for comparison of non-normally distributed continuous data within each group before and after treatment, and the Mann-Whitney U test was used for comparison between two groups; the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsThe observation group had a significantly higher response rate than the control group [48.4% (15/31) vs 27.1% (16/59), χ2=4.071, P=0.044]. The methods for blood purification in both groups could effectively improve total bilirubin, alanine aminotransferase, aspartate aminotransferase (AST), prothrombin time activity, serum creatinine (Scr), procalcitonin (PCT), C-reactive protein, eGFR, and MELD-Na score (all P<0.05), and both groups had significant reductions in platelet count (PLT) and hemoglobin (Hb) after treatment (all P<0.05), while there were no significant changes in blood urea nitrogen, albumin, and international normalized ratio after treatment (all P>0.05). There were significant differences between the two groups in the changes in AST, Scr, PCT, eGFR, MELD-Na score, Hb, and PLT after treatment (all P<0.05). ConclusionDPMAS sequential PE combined with CRRT can effectively remove inflammatory mediators, improve renal function, stabilize the internal environment of human body, and achieve a relatively good clinical efficacy.

ABSTRACT

Liver failure (LF) is a great trouble to the majority of patients due to its severe onset, many complications, difficult treatment, poor prognosis and other characteristics. This disease is liver injury caused by infection, hepatotoxic substances, autoimmunity, circulation disorders and other factors. It is a group of common clinical symptoms mainly manifested by coagulation disorders, jaundice, hepatic encephalopathy, ascites, and so on. In traditional Chinese medicine, it falls under the categories of "tympanites", "jaundice" and other diseases. At present, the research progress of Western medicine in the treatment of LF is slow, and its clinical application effect is still not ideal. In contrast, traditional Chinese medicine has a long history in the treatment of this disease, with over thousands of years of clinical practice and verification. It is characterized by exact efficacy and fewer side effects. The pathological mechanism of LF is extremely complex, involves a variety of signaling pathways, and is mainly related to inflammation, oxidative stress, liver fibrosis, cell apoptosis and other processes. In recent years, many studies have shown that traditional Chinese medicine can intervene in the occurrence and development of LF by mediating relevant signaling pathways in vivo, but there is still a lack of relevant summary. Therefore, this review summarized several signaling pathways related to the intervention of traditional Chinese medicine in LF by referring to and sorting out relevant literature worldwide, including nuclear factor kappa B (NF-κB), mitogen-activated protein kinase (MAPK), phosphatidylin-ositol-3-kinase/protein kinase B (PI3K/Akt), transforming growth factor-β/ drosophila mothers against decapentaplegic proteins (TGF-β/Smads), and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 (Nrf2/HO-1), and elaborated the specific mechanism of their intervention in LF. This paper aims to provide practical and effective pathways and corresponding mechanisms for the treatment of LF by traditional Chinese medicine, and to provide new ideas and a theoretical basis for the clinical treatment of LF and further scientific research.

ABSTRACT

Liver regeneration following injury aids the restoration of liver mass and the recovery of liver function. In the present study we investigated the contribution of megakaryocytic leukemia 1 (MKL1), a transcriptional modulator, to liver regeneration. We report that both MKL1 expression and its nuclear translocation correlated with hepatocyte proliferation in cell and animal models of liver regeneration and in liver failure patients. Mice with MKL1 deletion exhibited defective regenerative response in the liver. Transcriptomic analysis revealed that MKL1 interacted with E2F1 to program pro-regenerative transcription. MAPKAPK2 mediated phosphorylation primed MKL1 for its interaction with E2F1. Of interest, phospholipase d2 promoted MKL1 nuclear accumulation and liver regeneration by catalyzing production of phosphatidic acid (PA). PA administration stimulated hepatocyte proliferation and enhanced survival in a MKL1-dependent manner in a pre-clinical model of liver failure. Finally, PA levels was detected to be positively correlated with expression of pro-regenerative genes and inversely correlated with liver injury in liver failure patients. In conclusion, our data reveal a novel mechanism whereby MKL1 contributes to liver regeneration. Screening for small-molecule compounds boosting MKL1 activity may be considered as a reasonable approach to treat acute liver failure.

ABSTRACT

ObjectiveTo investigate the clinical value of serum creatinine-to-cystatin C ratio (CCR) in evaluating the prognosis of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). MethodsA retrospective analysis was performed for the clinical data of 130 patients with HBV-ACLF (treatment group) who were hospitalized in Department of Infectious Diseases, The First Affiliated Hospital of Soochow University, from January 2021 to November 2022. According to the treatment outcome, they were divided into survival group with 87 patients and death group with 43 patients; according to the presence or absence of infection, they were divided into infection group with 37 patients and non-infection group with 93 patients. A total of 30 individuals who underwent physical examination during the same period of time were enrolled as control group. Routine blood test results were collected on the day of admission, including white blood cell count, platelet count, neutrophil count, and lymphocyte count; serum creatinine, cystatin C, serum albumin (Alb), and prothrombin time (PT) were observed on the day of admission and on days 5, 10, and 15 of hospitalization, and related indicators were calculated, including CCR, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), CCR5 (CCR on day 5 after admission), ΔCCR5 (CCR on day 5 after admission minus CCR on the day of admission), CCR10 (CCR on day 10 after admission), ΔCCR10 (CCR on day 10 after admission minus CCR on day 5 after admission), CCR15 (CCR on day 15 after admission), and ΔCCR15 (CCR on day 15 after admission minus CCR on day 10 after admission). The above indicators were compared between the survival group and the death group and between the infection group and the non-infection group. The Mann-Whitney U test was used for comparison of continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups. The univariate and multivariate logistic regression analyses were used to investigate the influencing factors for disease prognosis; the receiver operating characteristic (ROC) curve was used to assess the value of CCR in predicting HBV-ACLF death events, and the DeLong test was used for comparison of the area under the ROC curve (AUC). ResultsThere were significant differences in CCR, NLR, PNI, PT, and Alb at baseline between the treatment group and the healthy control group (all P<0.001), and there were significant differences in CCR, NLR, and PT between the survival group and the death group on the day of admission (all P<0.05). Among the 130 patients with HBV-ACLF, there were 25 in the precancerous stage, 48 in the early stage, 32 in the intermediate stage, and 25 in the advanced stage, and there were significant differences in baseline CCR, PLR, and PT between the patients in different stages of HBV-ACLF (all P<0.05). There were significant differences in ΔCCR5 and NLR between the infection group and the non-infection group (P<0.05), and there were significant differences in ΔCCR5, CCR10, and CCR15 between the survival group and the death group (all P<0.05). The multivariate logistic regression analysis showed that ΔCCR5 (odds ratio [OR]=1.175, 95% confidence interval [CI]: 1.098‍ — ‍1.256, P<0.001), NLR (OR=0.921, 95%CI: 0.880‍ — ‍0.964, P<0.001), and PT (OR=0.921, 95%CI: 0.873‍ — ‍0.973, P=0.003) were independent influencing factors for the prognosis of HBV-ACLF patients. ΔCCR5 had an AUC of 0.774, a sensitivity of 0.687, and a specificity of 0.757, and the AUC of ΔCCR5+PT+NLR was 0.824, which was significantly higher than the AUC of ΔCCR5, NLR, or PT alone (all P<0.05). ConclusionΔCCR5, NLR, and PT can reflect the condition and prognosis of patients with HBV-ACLF and are independent predictive indicators for death events in patients with HBV-ACLF. The combination ofΔCCR5, PT, and NLR has the best predictive efficiency.

ABSTRACT

Liver failure is a common clinical syndrome with rapid progression and poor prognosis. Currently, there are still limited internal medical treatment methods for liver failure, and artificial liver support therapy is an effective treatment method. Non-bioartificial liver technology is widely used in clinical practice, and clinicians should determine the starting time, mode, and specific parameters of treatment according to the pathophysiological mechanism and dynamic evolution process of the disease, as well as the specific conditions of patients. Compared with non-bioartificial liver, biological artificial liver can better simulate the biological function of liver cells. At present, substantial progress has been made in its core technology, and related clinical studies are being conducted actively, suggesting a vast potential for future development. This article summarizes and discusses the optimization of non-bioartificial liver technology and the advances in biological artificial liver, in order to provide a reference for the clinical application and research of artificial liver technology.

ABSTRACT

Liver failure is a common clinical syndrome of severe liver disease with rapid progression and high mortality. Therefore, early intervention in pre-liver failure or “golden window” is of great significance in improving the prognosis of patients. Hepatitis B virus-related acute-on-chronic liver failure and alcohol-related acute-on-chronic liver failure are the main topics of studies on pre-liver failure. This article discusses the pathogenesis of pre-liver failure and artificial liver support therapy, so as to guide the reasonable and affective applications of artificial liver technology in clinical practice, promote related studies, and thereby reduce the mortality rate of patients with liver failure.

ABSTRACT

Artificial liver support system is one of the important therapies for liver failure, and in recent years, the role of non-bioartificial liver support system in the treatment of liver failure has been gradually recognized, with wide application in non-liver failure diseases. In clinical practice, various factors should be considered to reasonably select the timing and mode of non-bioartificial liver support therapy, and standardized, individualized, and precise treatment and optimal combination of different modes are the trend of the clinical application of artificial liver support therapy. There have been constant improvements in the key techniques of bioartificial liver support system such as seed cell source and bioreactor, and some of them have entered the stage of clinical trial. Although remarkable progress has been made in the clinical practice and research of artificial liver support therapy, there are still many challenges, and it is urgently needed to solve the problems of how to further improve its efficacy and safety through technological innovation and combination optimization and how to obtain higher-level evidence-based medical evidence through high-quality clinical trials.

ABSTRACT

Acute-on-chronic liver failure has complex conditions, rapid progression, and a high mortality rate, and further studies are still needed to clarify its pathogenesis and etiology. The establishment of animal models for acute-on-chronic liver failure can not only provide a good basis for exploring the pathogenesis of acute-on-chronic liver failure, but also provide an experimental basis for clinical treatment. Through a literature review, this article summarizes the methods commonly used to establish the animal models of acute-on-chronic liver failure, including carbon tetrachloride combined with LPS/GaIN, thioacetamide combined with LPS, serum albumin, and bile duct ligation. This article analyzes the characteristics of various animal models, so as to provide documentary and experimental bases for further exploration of more ideal animal models.

ABSTRACT

ObjectiveTo investigate whether menaquinone-4 (MK-4) can exert a protective effect against carbon tetrachloride (CCl4)-induced acute liver injury (ALI) in mice by alleviating ferroptosis. MethodsAfter adaptive feeding, adult male ICR mice, aged 8 weeks, were divided into Control group, MK-4 group, CCl4 model group (6-hour, 12-hour, and 24-hour), and MK-4+CCl4 group (6-hour, 12-hour, and 24-hour), with 6 mice in each group. The mice in the Control group were given intraperitoneal injection of an equal dose of corn oil; the mice in the MK-4 group were given intraperitoneal injection of 40 mg/kg MK-4 solution, followed by an equal dose of corn oil after 1 hour; the mice in the MK-4+CCl4 group (6-hour, 12-hour, and 24-hour) were given intraperitoneal injection of 40 mg/kg MK-4 solution, and after 1 hour, the mice in this group and the CCl4 model group (6-hour, 12-hour, and 24-hour) were given intraperitoneal injection of 0.3 mL/kg CCl4 solution, with samples collected at 6, 12, and 24 hours. HE staining was used to observe the pathological changes of mouse liver; Prussian blue staining was used to observe iron accumulation in liver tissue; a biochemical analyzer was used to measure the serum levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT); related kits were used to measure the levels of tissue iron content and the oxidative stress indices malondialdehyde (MDA) and glutathione (GSH) in liver homogenate; RT-PCR was used to measure the expression levels of ferroptosis marker genes (acyl-CoA synthetase long-chain family member 4 [ACSL4], prostaglandin-endoperoxide synthase 2 [PTGS2], and glutathione peroxidase 4 [GPX4]) and iron metabolism-related genes (hemojuvelin [HJV], transferrin receptor 1 [TFR1], and ferroportin [FPN]), and Western blot was used to measure the protein expression level of GPX4. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsIn the aging study, compared with the Control group, the CCl4 model group (6-hour, 12-hour, and 24-hour) had significant increases in liver weight coefficient and the serum levels of ALT and AST (all P<0.05), and HE staining also showed that liver injury gradually aggravated over time. Meanwhile, compared with the CCl4 model group (6-hour, 12-hour, and 24-hour), the MK-4+CCl4 (12-hour) group had significant reductions in liver weight coefficient and the serum levels of ALT and AST (all P<0.05), with a reduction in the necrotic area of liver tissue, and therefore, 12-hour mouse tissue samples were used for detection in the following study. Compared with the Control group, the CCl4 group had a significant increase in MDA and a significant reduction in GSH (both P<0.05), and compared with the CCl4 group, the MK-4+CCl4 group had a significant reduction in MDA and a significant increase in GSH (both P<0.05). Compared with the Control group, the CCl4 group had significant increases in the key ferroptosis indices ASCL4 and PTGS2 and a significant reduction in GPX4 (all P<0.05); compared with the CCl4 group, the MK-4+CCl4 group had significant reductions in the mRNA expression levels of ASCL4 and PTGS2 and a significant increase in the mRNA expression level of GPX4 (all P<0.05). Western blotting showed that compared with the Control group, the CCl4 group had a significant reduction in the protein expression level of GPX4 (P<0.05), and compared with the CCl4 group, the MK-4+CCl4 group had a significant increase in the protein expression level of GPX4 (P<0.05). Prussian blue staining showed that compared with the Control group, the CCl4 group had a significant increase in iron accumulation; after MK-4 intervention, compared with the CCl4 group, the MK-4+CCl4 group had a significant reduction in iron accumulation. As for the measurement of iron metabolism genes in mouse liver, compared with the Control group, the CCl4 group had a significant increase in iron content, significant reductions in the mRNA expression levels of FPN and HJV, and a significant increase in the mRNA expression level of TFR1 (all P<0.05); after protection with MK-4, there was a significant reduction in iron content, significant increases in the mRNA expression levels of FPN and HJV, and a significant reduction in the mRNA expression level of TFR1 (all P<0.05). ConclusionMK-4 intervention in advance can alleviate CCl4-induced ALI in mice, possibly by inhibiting ferroptosis and improving the expression of iron metabolism-related genes in mouse liver.

ABSTRACT

ObjectiveTo investigate the differences in clinical features and mortality rate between native patients with chronic liver failure (CHF) and migrated patients with CHF after treatment with double plasma molecular adsorption system (DPMAS) in high-altitude areas. MethodsA total of 63 patients with CHF who received DPMAS treatment in the intensive care unit of General Hospital of Tibet Military Command from January 2016 to December 2021 were enrolled, and according to their history of residence in high-altitude areas, they were divided into native group with 29 patients and migrated group with 34 patients. The two groups were compared in terms of baseline data and clinical features before and after DPMAS treatment. The independent-samples t test was used for comparison of normally distributed continuous data between groups, and the paired t-test was used for comparison before and after treatment within each group; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups, and the Wilcoxon signed rank sum test was used for comparison before and after treatment within each group; the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves, and the Log-rank test was used for comparison of the risk of death. ResultsCompared with the native group, the migrated group had a significantly higher proportion of Chinese Han patients (χ2=41.729, P<0.001), and compared with the migrated group, the native group had a significantly longer duration of the most recent continuous residence in high-altitude areas (Z=3.364, P<0.001). Compared with the native group, the migrated group had significantly higher MELD score and incidence rates of hepatic encephalopathy, hepatorenal syndrome, and gastrointestinal bleeding (Z=2.318, χ2=6.903, 5.154, and 6.262, all P<0.05). Both groups had significant changes in platelet count (PLT), hemoglobin count (HGB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin, total bilirubin (TBil), direct bilirubin (DBil), lactate dehydrogenase (LDH), creatinine (Cr), and international normalized ratio (INR) after DPMAS treatment (all P<0.05). Before DPMAS treatment, compared with the native group, the migrated group had significantly higher levels of ALT, AST, TBil, DBil, LDH, Cr, BUN, and INR (all P<0.05) and a significantly lower level of HGB (P<0.05); after DPMAS treatment, compared with the native group, the migrated group had significantly greater reductions in PLT and HGB (both P<0.05) and still significantly higher levels of ALT, AST, TBil, DBil, LDH, BUN, and INR (all P<0.05). The 60-day mortality rate of patients after DPMAS treatment was 52.5% (95% confidence interval [CI]: 41.7 — 63.8) in the native group and 81.3% (95%CI: 77.9 — 85.6) in the migrated group. Compared with the native group (hazard ratio [HR]=0.47, 95%CI: 0.23 — 0.95), the migrated group had a significant increase in the risk of death on day 60 (HR=2.14, 95%CI: 1.06 — 4.32, P=0.039). ConclusionCompared with the native patients with CHF in high-altitude areas, migrated patients have a higher degree of liver impairment, a lower degree of improvement in liver function after DPMAS treatment, and a higher mortality rate. Clinical medical staff need to pay more attention to migrated patients with CHF, so as to improve their survival rates.

ABSTRACT

Liver failure (LF), as a clinical syndrome of severe hepatocyte damage and liver dysfunction, has become a major obstacle to human health due to the triple superposition of high mortality, high morbidity, and high medical resource depletion. It is of great significance to further study the core factors of the disease and supplementary treatment methods to improve the survival rate of patients with LF. The pathogenesis of LF is complex, and mitochondrion is one of the sensitive organelles in hepatocytes and the central link of intracellular energy metabolism. A large number of studies have shown that the structure and function of mitochondria in hepatocytes are changed in LF, and the abnormal structure and function of mitochondria play an important role in the process of LF disease. Among them, multiple factors such as mitochondrial respiratory chain disorder, mitochondrial DNA damage, mitochondrial permeability transition pore opening, mitochondrial quality control imbalance, and mitochondrial oxidative stress are intertwined, forming a complex and unified whole network, which becomes the key node affecting the progression of LF. In recent years, researchers have begun to study drugs that can regulate the function of liver mitochondria to prevent and treat LF. With the deepening of research, traditional Chinese medicine has made breakthroughs in the prevention and treatment of LF. Many studies have confirmed that traditional Chinese medicine can play a role in the prevention and treatment of LF by protecting mitochondrial function, which can be summarized as reducing liver cell damage, inhibiting liver cell death, and promoting liver cell regeneration, so as to effectively compensate for liver function and promote the recovery of liver parenchyma quality and function. This article summarized the structure and function of mitochondria, the relationship between LF and mitochondria, and the research on the intervention of mitochondrial function in the field of traditional Chinese medicine to prevent and treat LF, so as to provide certain ideas and references for the clinical treatment of LF with traditional Chinese medicine.

ABSTRACT

Acute fulminant hepatic failure is a condition in which a healthy liver deteriorates rapidly following an insult, resulting in the impairment of its synthetic functions. This condition is rare and is associated with high fatality rates. We report the case of a 19-year-old male who was brought to the emergency room in an unconscious state with jaundice and persistent fever for 2–3 weeks after recently commencing intravenous use of morphine. He was found to be hepatitis B surface antigen reactive, and his laboratory tests indicated severe liver dysfunction with elevated levels of serum bilirubin, aspartate transaminase, alanine transaminase, gamma-glutamyl transferase, and International normalized ratio. The patient was diagnosed with fulminant liver failure with coagulopathy and hepatic encephalopathy. The patient’s family was addressed and counseled regarding the urgent need for liver transplantation. However, due to a lack of funds and insurance, supportive treatment was the only option left. Despite all supportive measures, the patient expired within 48 h. This case highlights the importance of various socioeconomic issues involved with liver transplantation, as in a resource-limited setting, urgent transplantation seems nearly impossible. In addition, this case report raises certain ethical issues that need consideration, particularly in an injection drug use scenario. It also highlights the importance of addressing the rising issue of injection drug use among youth, particularly in the regions of Punjab.

ABSTRACT

La enfermedad poliquística renal autosómica dominante es considerada la enfermedad renal genética más frecuente y es la cuarta causa de enfermedad renal crónica a nivel mundial. Afecta a cerca de 1 por cada 1000 nacidos vivos. La enfermedad poliquística hepática es la manifestación extrarrenal más frecuente de la enfermedad poliquística renal. La cirrosis hepática constituye un hallazgo tardío en esta enfermedad y su presentación es más común en el anciano, y la descompensación de la enfermedad con insuficiencia hepática como causa de muerte. Presentamos el caso de un paciente masculino de 60 años con antecedentes patológicos personales de la enfermedad poliquística renal con ascitis a tensión, y edemas en ambos miembros inferiores con datos de insuficiencia hepática y evolución desfavorable hasta su fallecimiento. Aunque la presencia de la falla hepática se asocia a un pronóstico precario, la detección precoz puede suponer el inicio de un tratamiento oportuno y apropiado que puede ser beneficioso.


Autosomal dominant polycystic kidney disease is considered the most common genetic kidney disease and the fourth leading cause of chronic kidney disease worldwide. It affects about 1 in 1,000 live births. Polycystic liver disease is the most common extrarenal manifestation of polycystic kidney disease. Liver cirrhosis is a late finding in this disease and its presentation is more common in the elderly. Decompensation of the disease, with liver failure as the cause of death, is rare in polycystic liver disease. We report the case of a 60-year-old male patient with a personal pathological history of polycystic kidney disease with tense ascites and edema in both lower limbs, with evidence of liver failure and unfavorable evolution until his death. Although the presence of liver failure is associated with poor prognosis, its early detection may mean the initiation of timely and appropriate treatment that may be beneficial.

ABSTRACT

Acute hepatitis of unknown origin in children has been recently described in the literature, and a case definition has also been proposed for this condition. The exact etiology is unknown and exclusion of infectious, metabolic, autoimmune and toxin mediated injuries is essential. Management for this condition is supportive, but some may require liver transplantation. Infection prevention and control practices are important as the etiology remains unidentified.
