Delphinidin or α-amyrin attenuated liver steatosis and metabolic disarrangement in rats fed a high-fat diet.

Non-alcoholic fatty liver disease (NAFLD) is a liver pathology concomitant with metabolic disarrangement. This study assessed the therapeutic impacts of delphinidin, an anthocyanin, or α-amyrin, a pentacyclic triterpenoid, on NAFLD in rats and the underlying mechanisms involved. NAFLD was established by feeding a high-fat diet (HFD) for 10 weeks, either alone or in combination with delphinidin (40 mg/kg, oral) or α-amyrin (20 mg/kg, oral). Delphinidin or α-amyrin ameliorated the metabolic and histopathological perturbations induced by HFD. These compounds markedly attenuated NAFLD-induced hepatic steatosis, as evidenced by a substantial decrease in body weight, insulin resistance, and liver and adipose tissue indices. Alongside normalization of the atherogenic index, both improved HFD-mediated abnormalities in serum lipids, liver enzymes, leptin, and ghrelin levels. Moreover, their intervention activated the NFE2 like bZIP transcription factor 2 and heme oxygenase 1 pathways and abrogated HFD-triggered activation of mitogen-activated protein kinase 1 signaling. These remedies inhibited hepatic apoptosis and modulated the gene expression of lipogenic enzymes. Furthermore, histological analysis corroborated the suppression of lipid accumulation and amelioration of hepatic architecture in the treated rats. Our findings highlight the hepatoprotective value of delphinidin or α-amyrin against NAFLD and related metabolic diseases through their insulin-sensitizing, anti-inflammatory, antioxidant, and antiapoptotic effects.

The effectiveness of liver function tests in the prediction of mortality in patients with COVID-19.

To evaluate the impact of liver function test abnormalities on mortality in critically ill coronavirus disease- 2019 patients. The single-centre, retrospective study was conducted at the Department of Anaesthesiology and Reanimation, Mersin City Training and Research Hospital, Turkiye, and comprised data from March 2020 to January 2022 of patients with positive real-time reverse transcription polymerase chain reaction test on nasopharyngeal swab sample for coronavirus disease-2019. Comorbidities, demographic data, admission to and discharge from the intensive care unit, Acute Physiology and Chronic Health Evaluation II scores, complete blood count on the first and second day of hospitalisation, coagulation parameters, biochemical analysis, 7-day, 28-day and total mortality of the patients in the intensive care unit were recorded. The patients were then divided into groups, with Group 1 having patients with normal liver enzymes, Group 2 having patients with abnormal liver enzymes, and Group 3 having patients with liver damage. Data was analysed using SPSS 20. Of the 940 subjects, 587(62.4) were males and 353(37.6) were females. The overall mean age of the patients was 67.11±16.65 years. There were 395(42%) patients in Group 1, 534(56.8%) in Group 2 and 11(1.2%) in Group 3. Gamma-glutamyl transferase-1s, aspartate aminotransferase-2nd and albumin-2nd were significant predictors of mortality (p<0.05). High gamma-glutamyl transferase, aspartate aminotransferase and low albumin levels in critically ill coronavirus disease-2019 patients could be considered indicators of high mortality rate.

Histologic Patterns of Ribociclib-induced Liver Injury

Abstract Introduction/Objective Ribociclib, a cyclin dependent kinase (CDK) 4/6 inhibitor, used in the treatment of advanced breast carcinomas, can cause liver injury, often manifesting as elevated liver enzymes. However, the histologic patterns of liver injury caused by Ribociclib have not been well-documented. Our study aims to explore these patterns in patients undergoing Ribociclib treatment. Methods/Case Report Five female patients receiving Ribociclib treatment for breast carcinomas and undergoing liver biopsy post-transaminitis in the past seven years (2017-2024) were identified using our institution’s electronic medical record. Clinical information was collected, and liver biopsies were reviewed for histologic injury patterns. Results (if a Case Study enter NA) The mean age of the patients was 47 years (range 38-68). All patients had liver enzyme abnormalities after starting with Ribociclib: mean time to peak of ALT and AST was 75 days (range 36-125). Mean peak enzyme levels (IU/L) for ALT and AST were 685 and 420, respectively. Liver biopsy showed an acute hepatitis pattern of injury in all five patients: centrizonal confluent necrosis (n=3) and lobular spotty necrosis (n=2). Other findings included: mild cholestasis (n=1), interface hepatitis (n=2), focal bile duct injury (n=2), and mild macrovesicular steatosis without steatohepatitis (n=1). Portal inflammation was mild to moderate, comprising a mixed lymphoplasmacytic infiltrate. One patient had moderate periportal fibrosis without bridging. Ribociclib was withdrawn in all patients; three patients received prednisolone treatment. Three patients were rechallenged with Abemaciclib and two with Palbociclib. All patients had resolution of liver function tests after cessation of Ribociclib therapy. Mean time to normalization of ALT and AST was 46 days (range 30-72) and 62 days (range 30-96), respectively, after holding Ribociclib. Conclusion Ribociclib predominantly causes an acute hepatitis pattern of liver injury and of varying severity. Drug cessation, with or without steroid therapy, and switching to a less hepatotoxic CDK 4/6 inhibitor can be sufficient to restore normal liver function. Screening for liver dysfunction with baseline enzyme tests prior to Ribociclib treatment, as well as serial testing to trend enzyme levels, may help prevent severe liver injury.

Nebivolol-Induced Hepatoxicity: A Case Report.

Nebivolol, despite its favourable safety profile, can lead to significant liver injury.Clinicians should remain vigilant and consider routine liver function monitoring in patients prescribed nebivolol, particularly if they present with nonspecific symptoms or abnormal liver enzyme tests.Early recognition and prompt discontinuation of the offending agent are crucial in preventing severe outcomes.

Comparative Analysis of Liver Enzyme Changes Before and After Korean Medicine Treatment in People with Obesity: A Retrospective, Multicenter, Observational Study

This retrospective, multicenter, observational study aimed to evaluate the effects of herbal medicine treatment on liver function in obese patients exhibiting elevated liver enzymes. Conducted from May 2023 to April 2024 at various Korean medicine clinics, the study included 84 patients who underwent herbal treatments for obesity. All participants had at least one liver function test (LFT) showing elevated levels of aspartic amino transferase (AST), alanine amino transferase (ALT), or gamma glutamyl transferase (GGT), and a subsequent LFT performed after a minimum of 90 days. The study excluded patients with potential confounding factors such as hepatitis, antibiotic usage, or recent surgeries.&lt;/br&gt;The study showed significant reductions in AST, ALT, and GGT levels, with AST and ALT improving to within the normal range and GGT approaching normal levels. Patients also experienced statistically significant reductions in weight and BMI, meeting the minimum clinically important difference threshold.&lt;/br&gt;These findings suggest that herbal treatments for obesity are not only safe for patients with obesity-related liver enzyme abnormalities but also effective in improving liver function. This study shows that herbal treatment is effective in the management of obesity-related liver disease and confirms the safety and efficacy of an obesity treatment herbal formula containing ephedra. Larger prospective studies are needed to confirm these findings.

Characteristics of intestinal flora in nonobese nonalcoholic fatty liver disease patients and the impact of ursodeoxycholic acid treatment on these features.

The study aimed to investigate the alterations in gut microbiota among nonobese individuals with nonalcoholic fatty liver disease (NAFLD) and their response to treatment with ursodeoxycholic acid (UDCA). A total of 90 patients diagnosed with NAFLD and 36 healthy subjects were recruited to participate in this study. Among them, a subgroup of 14 nonobese nonalcoholic steatohepatitis (NASH) were treated with UDCA. Demographic and serologic data were collected for all participants, while stool samples were obtained for fecal microbiome analysis using 16S sequencing. In nonobese NAFLD patients, the alpha diversity of intestinal flora decreased (Shannon index, p < 0.05), and the composition of intestinal flora changed (beta diversity, p < 0.05). The abundance of 20 genera, including Fusobacterium, Lachnoclostridium, Klebsiella, etc., exhibited significant changes (p < 0.05). Among them, nine species including Fusobacterium, Lachnoclostridium, Klebsiella, etc. were found to be associated with abnormal liver enzymes and glucolipid metabolic disorders. Among the 14 NASH patients treated with UDCA, improvements were observed in terms of liver enzymes, CAP values, and E values (p < 0.05), however, no improve the glucolipid metabolism. While the alpha diversity of intestinal flora did not show significant changes after UDCA treatment, there was a notable alteration in the composition of intestinal flora (beta diversity, p < 0.05). Furthermore, UCDA treatment led to an improvement in the relative abundance of Alistipes, Holdemanella, Gilisia, etc. among nonobese NASH patients (p < 0.05). Nonobese NAFLD patients exhibit dysbiosis of the intestinal microbiota. UDCA can ameliorate hepatic enzyme abnormalities and reduce liver fat content in nonobese NASH patients, potentially through its ability to restore intestinal microbiota balance.

Liver-related aspects of valoctocogene roxaparvovec gene therapy for hemophilia A: expert guidance for clinical practice

AbstractAdeno-associated virus–based gene therapy (valoctocogene roxaparvovec) is an attractive treatment for hemophilia A. Careful clinical management is required to minimize the risk of hepatotoxicity, including assessment of baseline liver condition to determine treatment eligibility and monitoring liver function after gene therapy. This article describes recommendations (developed by a group of hemophilia experts) on hepatic function monitoring before and after gene therapy. To prevent harmful liver-related effects, gene therapy is contraindicated in patients with uncontrolled liver infections, autoimmune hepatitis, liver stiffness ≥8 kPa, or cirrhosis. Before using gene therapy in patients with liver steatosis or other liver disorders, the risk of liver damage should be considered using a highly individualized approach. Treatment is not recommended in patients with abnormal liver enzymes, including alanine aminotransferase (ALT) at any level above the upper limit of normal (ULN). Therefore, pretreatment assessment of liver health should include laboratory tests, abdominal ultrasound, and liver stiffness measurements by transient elastography (TE). In the first year after therapy, ALT levels should be monitored 1 to 2 times per week to detect elevations ≥1.5× ULN, which may require immunosuppressant therapy. Patients with ALT elevation should receive prednisone 60 mg/d for 2 weeks, followed by stepwise tapering when ALT returns to baseline. ALT monitoring should continue long term (every 3-6 months), along with abdominal ultrasound (every 6 months) and TE (yearly) evaluations. When patients with good liver health are selected for treatment and closely monitored thereafter, ALT elevations can be promptly treated and are expected to resolve without long-term hepatic sequelae.

Altered Liver Enzyme Markers in Patients with Asymptomatic, and Mild Omicron Infection: A Retrospective Study.

The emergence of the SARS-CoV-2 Omicron variant has posed a significant global public health challenge. Elucidating the laboratory profiles of individuals infected with this variant is crucial for assessing organ damage. This study aimed to investigate the variations in liver function tests and their correlation with demographic characteristics and inflammatory markers in patients with early Omicron variant infections. A retrospective cohort study was conducted on 1133 mild or asymptomatic COVID-19 cases at Tianjin First Central Hospital. Data on age, gender, body mass index (BMI), and serum markers were collected and analyzed. Statistical analyses were performed using SPSS software, version 24.0. Abnormal liver function parameters, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and total bilirubin (TBIL), were observed in 314 (27.71%) patients. "Hepatocellular type" was identified in 56 (4.94%) patients, "cholestatic type" in 185 (16.33%) patients, and "mixed type" in 73 (6.44%) patients. In the mixed group, we observed a pronounced elevation in the levels of ALT, AST, and GGT. Moreover, the hepatocellular group exhibited a statistically significant increase in AST and ALT concentrations relative to both the normal and cholestatic groups. Notably, the cholestatic group demonstrated a substantial increment in ALP levels. Males had a significantly higher prevalence of "abnormal liver enzyme markers" compared to females. Patients with "abnormal liver enzyme markers" exhibited significantly decreased immunoglobulin G (IgG) levels and elevated levels of inflammatory markers, including procalcitonin (PCT), interleukin-6 (IL6), as well as C-reactive protein (CRP) compared to normal group. Logistic regression analysis revealed that male gender and PCT levels were significantly associated with the risk of abnormal liver enzyme markers. Patients in hepatocellular group were likely accompanied with high CRP levels, whereas those in the cholestatic type were associated with high IL6 levels. Early Omicron infection might cause liver stress response. Elevated liver enzyme marker levels were correlated with age, gender, inflammatory factors, and IgG.

Drug-induced liver injury associated with atypical generation antipsychotics from the FDA Adverse Event Reporting System (FAERS)

BackgroundRecent studies have shown that liver enzyme abnormalities were not only seen with typical antipsychotics (APs) but also with atypical antipsychotics (AAPs). During the last 20 years, the hepatotoxicity of various antipsychotics received much attention. However, systematic evaluations of hepatotoxicity associated with APs are limited.MethodsAll drug related hepatic disorders cases were retrieved from the FDA Adverse Event Reporting System (FAERS) database using standardized MedDRA queries (SMQ) from the first quarter of 2017 to the first quarter of 2022. Patient characteristics and prognosis were assessed. In this study, a case/non-case approach was used to calculate reporting odds ratio (RORs) and 95% confidence intervals (CIs). We calculated the drug-induced liver injury (DILI) RORs for each AAPs.ResultsA total of 408 DILI cases were attributed to AAPs during the study period. 18.6% of these were designated as serious adverse event (SAE), which include death (19.74%), hospitalization (68.42%), disability (2.63%), and life-threatening (9.21%) outcomes. The RORs values in descending order were: quetiapine (ROR = 0.782), clozapine (ROR = 0.665), aripiprazole (ROR = 0.507), amisulpride (ROR = 0.308), paliperidone (ROR = 0.212), risperidone (ROR = 0.198), ziprasidone (0.131).ConclusionThe result found in our study was that all AAPs didn’t have a significant correlation with increased hepatotoxicity. Future analysis of the FAERS database in conjunction with other data sources will be essential for continuous monitoring of DILI.

Evaluation of oral silymarin formulation efficacy in prevention of doxorubicin induced hepatotoxicity in patients with non-metastatic breast cancer.

Chemotherapy-induced hepatotoxicity is a common complication in breast cancer patients, especially with doxorubicin-containing regimens. Liver enzyme abnormality is reported in 34.8% of patients undergoing AC-T regimen and fatty liver is reported in 30% to 50% of cases. Antioxidant and anti-inflammatory properties of silymarin, a polyphenolic flavonoid extract derived from Silybum marianum, may be useful in preventing chemotherapy-induced hepatotoxicity. This study evaluated the effect of oral silymarin for preventing doxorubicin induced hepatotoxicity in non-metastatic breast cancer patients. In this triple-blind, placebo-controlled clinical trial, 50 patients with non-metastatic breast cancer were assigned to receive either 140 mg silymarin tablets or the placebo three times daily for 63 days and were evaluated for liver function test before the study and at the end of each chemotherapy cycle (every 3 weeks) for 4 cycles. In addition, an ultrasonography assessment was performed upon entry and the end of the study. Based on ultrasonography, the fatty liver grade was significantly higher in the placebo group at the end of the study. Moreover, the serum levels of aspartate aminotransferase (p = 0.015) and alkaline phosphatase (p = 0.004) at 6-week intervals, and the serum level of alkaline phosphatase (p = 0.002) at 9-week intervals were significantly lower in the silymarin group. Oral formulation of silymarin 420 mg/day for 63 days significantly prevented hepatotoxicity caused by doxorubicin in patients with non-metastatic breast cancer mostly based on liver ultrasonography but not laboratory parameters. Further investigations are suggested on different doses, durations and formulations of silymarin, particularly nano-formulations for increasing its oral bioavailability.

Patient with cryptogenic cirrhosis

Cryptogenic cirrhosis is cirrhosis of uncertain etiology, with no definitive clinical and histological criteria for a specific disease. More than half of such patients are women, the average age is about 60, and patients generally have only mild liver enzyme abnormalities. Cryptogenic cirrhosis's pathophysiology is unknown; therefore, further research is required to elucidate the underlying etiology. The problem of liver cirrhosis is extremely important since this pathology occurs mainly in young and healthy people. In patients with cryptogenic cirrhosis, aminotransferase (AST and ALT) levels are usually only mildly elevated or normal. In our case report, a 41-year-old male patient was approved to the emergency department due to migraine pain. Liver enzymes were high in the blood analysis taken from the patient. As a result of the liver ultrasound carried out on the patient, it was reported to have decreased liver size and irregular boundaries and compatible with chronic liver disease. The patient used various analgesics due to migraine in his 20s. However, no cause could be identified for the patient's liver failure.

Pharmacological benefits of durva swaras (Cynodon dactylon L. Pers.) administration in APAP-induced liver injury model of mice - Assessment by metabolic and inflammatory markers.

Liver derangement underlies the development of metabolic syndrome in perimenopause. Previously, we have observed that durva swaras (DS) improved metabolic-associated fatty liver disease (MAFLD) and abnormal liver enzymes (aspartate aminotransferase and alanine aminotransferase) along with other complications of menopause in ovariectomized rats. We aimed to decipher the hepatoprotective mechanisms of DS in acetaminophen (APAP)-induced liver injury model, which is analogous to the pathophysiology of MAFLD. Male Swiss albino mice were distributed into three groups at random. Group I (Control) was administered with vehicle (distilled water) for 7 days. Group II (APAP) received vehicle for the first 6 days and APAP (350 mg/kg - single dose) on the 7th day. Group III (APAP + D) received test compound DS (quality complied) at a dose of 133 mg/kg for 6 days and APAP (350 mg/kg - single dose) on the 7th day. Subsequently, blood and liver tissues were subjected to biochemical, ultrastructural, and gene expression analysis. DS pretreatment protected the liver from APAP-induced disruption of sinusoids and necrosis. DS prevented the elevation of liver enzymes - AST and ALT induced by APAP. Importantly, DS inhibited the APAP-elicited increase in messenger ribonucleic acid levels of hepatic nuclear factor-kappa beta (NF-κB) and pro-inflammatory cytokines, namely interleukin-1 beta, interleukin 6, and tumor necrosis factor-alpha. Moreover, DS activated gene expression of nuclear factor erythroid 2-related factor 2 and liver-X-receptor-alpha (LXR-α) to combat the liver damage. DS hinders APAP-induced liver damage by activating LXR-α and inhibiting the NF-κB-associated pro-inflammatory cytokine gene expression. These observations confirm the protective role of DS in metabolic dysfunction-associated liver conditions.

Pediatric inflammatory multisystem syndrome or Kawasaki disease - continuous challenges in Pediatrics - case report

Introduction. Kawasaki disease (KD) and pediatric inflammatory multisystem syndrome (PIMS) are similar vasculitis conditions affecting medium and small vessels, particularly the coronary arteries. This study aimed to highlight diagnostic and treatment challenges in a case initially diagnosed as PIMS, which evolved into atypical KD. Materials and methods. A 2-year-10-month-old male was admitted with a high fever persisting for 6 days, unresponsive to antipyretics. Results. On admission, the patient exhibited a poor general condition, pale skin, non-pruritic erythematous rash, and enlarged, non-painful lymph nodes. Laboratory tests showed elevated inflammatory markers, leukocytosis with neutrophilia, hypoalbuminemia, liver enzyme abnormalities, altered cardiac markers, and elevated D-dimers, but no initial echocardiographic changes. Positive SARS-CoV-2 antibodies led to an initial PIMS diagnosis, and treatment with intravenous methylprednisolone, antiplatelet, anticoagulant therapy, and hepatoprotective agents was started. The patient’s condition initially improved but then worsened with febrile spikes, rash, neutropenia, thrombocytopenia, anemia, and coronary artery dilation on echocardiography. This led to a diagnosis of KD with atypical onset, and treatment with immunoglobulin, antiplatelet, and anticoagulant therapy was initiated. The patient’s condition improved slowly. Conclusions. KD and PIMS share overlapping characteristics, making them difficult to distinguish. There is no definitive criterion to differentiate KD and PIMS, leading to potential diagnostic errors.

Determining the association between systematic lupus erythematosus and the occurrence of primary biliary cirrhosis: a systematic review and meta-analysis.

Autoimmune diseases often coexist; however, the concomitant occurrence of systemic lupus erythematosus (SLE) and primary biliary cirrhosis (PBC) is rare. Therefore, this study aims to provide a comprehensive summary of evidence regarding the co-occurrence of SLE and PBC. PubMed, Web of Science, ScienceDirect , and Google Scholar databases were systematically and comprehensively searched for records published up to February 2024. Full-text articles that aligned with the study's aim were included, while those published in languages other than English and those designed as case reports, reviews, conference abstracts, or editorials were excluded. Statistical analyses were performed using Comprehensive Meta-Analysis software, and methodological quality was assessed using the Newcastle-Ottawa Scale. Only 14 studies that met the inclusion criteria with 3944 PBC and 9414 SLE patients were included for review and analysis. Pooled data analysis revealed that approximately 1.1% of SLE patients have concomitant PBC (range: 0.02-7.5%), while around 2.7% of PBC patients concurrently have SLE (range: 1.3-7.5%). Furthermore, qualitative data analysis indicated that the prevalence of PBC in SLE patients presenting with hepatic dysfunction or abnormal liver enzymes ranges from 2 to 7.5%. Although the concomitant occurrence of SLE and PBC is rare, the small proportion of patients where these diseases coexist warrants close monitoring by clinicians. This underscores the importance of surveillance to prevent their co-occurrence.

Histopathological impact of SARS-CoV-2 on the liver: Cellular damage and long-term complications.

Coronavirus disease 2019 (COVID-19), caused by the highly pathogenic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), primarily impacts the respiratory tract and can lead to severe outcomes such as acute respiratory distress syndrome, multiple organ failure, and death. Despite extensive studies on the pathogenicity of SARS-CoV-2, its impact on the hepatobiliary system remains unclear. While liver injury is commonly indicated by reduced albumin and elevated bilirubin and transaminase levels, the exact source of this damage is not fully understood. Proposed mechanisms for injury include direct cytotoxicity, collateral damage from inflammation, drug-induced liver injury, and ischemia/hypoxia. However, evidence often relies on blood tests with liver enzyme abnormalities. In this comprehensive review, we focused solely on the different histopathological manifestations of liver injury in COVID-19 patients, drawing from liver biopsies, complete autopsies, and in vitro liver analyses. We present evidence of the direct impact of SARS-CoV-2 on the liver, substantiated by in vitro observations of viral entry mechanisms and the actual presence of viral particles in liver samples resulting in a variety of cellular changes, including mitochondrial swelling, endoplasmic reticulum dilatation, and hepatocyte apoptosis. Additionally, we describe the diverse liver pathology observed during COVID-19 infection, encompassing necrosis, steatosis, cholestasis, and lobular inflammation. We also discuss the emergence of long-term complications, notably COVID-19-related secondary sclerosing cholangitis. Recognizing the histopathological liver changes occurring during COVID-19 infection is pivotal for improving patient recovery and guiding decision-making.

Decreased Hepatic Functional Reserve Increases the Risk of Piperacillin/Tazobactam-Induced Abnormal Liver Enzyme Levels: A Retrospective Case-Control Study.

Piperacillin/tazobactam (PIPC/TAZ), which is a combination of a beta-lactam/beta-lactamase inhibitor, often causes liver enzyme abnormalities. The albumin-bilirubin (ALBI) score is a simple index that uses the serum albumin and total bilirubin levels for estimating hepatic functional reserve. Although patients with low hepatic reserve may be at high risk for drug-induced liver enzyme abnormalities, the relationship between PIPC/TAZ-induced abnormal liver enzymes levels and the ALBI score remains unknown. This study aimed to elucidate the relationship between PIPC/TAZ-induced abnormal liver enzyme levels and the ALBI score. This single-center retrospective case-control study included 335 patients. The primary outcome was PIPC/TAZ-induced abnormal liver enzyme levels. We performed COX regression analysis with male gender, age (≥75 years), alanine aminotransferase level (≥20 IU/L), and ALBI score (≥-2.00) as explanatory factors. To investigate the influence of the ALBI score on the development of abnormal liver enzyme levels, 1:1 propensity score matching between the ≤-2.00 and ≥-2.00 ALBI score groups was performed using the risk factors for drug-induced abnormal liver enzyme levels. The incidence of abnormal liver enzyme levels was 14.0% (47/335). COX regression analysis revealed that an ALBI score ≥-2.00 was an independent risk factor for PIPC/TAZ-induced abnormal liver enzyme levels (adjusted hazard ratio: 3.08, 95% coefficient interval: 1.207-7.835, P = 0.019). After 1:1 propensity score matching, the Kaplan-Meier curve revealed that the cumulative risk for PIPC/TAZ-induced abnormal liver enzyme levels was significantly higher in the ALBI score ≥-2.00 group (n = 76) than in the <-2.00 group (n = 76) (P = 0.033). An ALBI score ≥-2.00 may predict the development of PIPC/TAZ-induced abnormal liver enzyme levels. Therefore, frequent monitoring of liver enzymes should be conducted to minimize the risk of severe PIPC/TAZ-induced abnormal liver enzyme levels in patients with low hepatic functional reserve.

Clinical characteristics and natural history of porto-sinusoidal vascular disease: A cohort study of 234 patients in China.

Porto-sinusoidal vascular disease (PSVD) is an under-recognized and under-diagnosed disease. The purpose of this study was to investigate the clinical features and prognosis of PSVD. The patients who underwent liver biopsies were analyzed retrospectively. The clinical and pathological data were reviewed and screened according to the latest diagnostic criteria of PSVD. A total of 234 patients were diagnosed as PSVD, including 103 patients presented with portal hypertension (PH) and 131 patients without PH. At baseline, the alanine aminotransferase (ALT) and γ-glutamyl transpeptidase (GGT) levels were higher in the no-PH group. The liver stiffness increased in the PH group. In histological review, obliterative portal venopathy, sinusoidal dilatation and architectural disturbance were more common in the PH group, while portal tract abnormalities were more widely distributed in the no-PH group. After a median follow-up of 43.6 months, the survival rate of patients with baseline liver decompensation was 76.0%, and that of patients at a liver compensated stage in the PH group was 98.7%. First variceal bleeding occurred in 13.8% of patients with gastric-oesophageal varices. None of the patients in the no-PH group developed portal hypertension during follow-up. PSVD can manifest as PH or mild liver enzyme abnormalities. There are significant differences in pathological features among patients with different clinical manifestations. Recurrent ascites are the main cause of death in PSVD patients. However, patients without PH have a slow disease progression, with recurrent elevated GGT levels being their main clinical feature.

Liver function tests, CD4+ counts, and viral load among people living with HIV on dolutegravir compared to efavirenz-based cART; a comparative cross-sectional study

BackgroundRecently, dolutegravir-based therapy has become the first-line treatment when compared to others. However, dolutegravir-associated side effects in the liver and levels of efficacy haven't been addressed yet in underdeveloped countries such as Ethiopia. ObjectiveThe purpose of this study was to compare liver function tests, CD4+ counts, and viral load among people living with HIV on dolutegravir and efavirenz-based antiretroviral regimens at Debre Markos Comprehensive Specialized Hospital in Northwest Ethiopia. MethodsAn institutional-based comparative cross-sectional study was carried out from May 20 to July 10, 2020. An equal number of dolutegravir and efavirenz-prescribed patients (n = 53 each) for 6 months and above were included, and a judgmental sampling technique was used. A comparison of categorical and continuous parameters was analyzed with chi-square and an independent t-test, respectively, using SPSS version 26. A multivariable logistic regression was conducted and considered statistically significant at a p-value of <0.05. ResultsThe magnitude of liver enzyme (AST/ALT) abnormalities was 22.4 % (12/53) and 30.2 % (16/53) among dolutegravir- and efavirenz-prescribed patients, respectively. The dolutegravir group had significantly higher mean CD4+ counts than the efavirenz group (589.40 ± 244.38 vs. 450.64 ± 203.54 cell/mm3; p = 0.002). The efavirenz group had a significantly higher mean viral load than the dolutegravir group (783.83 ± 476.82 vs. 997.98 ± 439.11 cp/ml; p = 0.032). There was a statistically insignificant difference in AST (p = 0.709) or ALT (p = 0.687) between dolutegravir and efavirenz-based regimens. The multivariable logistic regression analysis revealed that BMI ≥25 kg/m2 was associated with liver enzyme abnormalities (AOR = 6.60, 95 % CI: 1.17, 42.82). ConclusionA dolutegravir-based regimen was more likely to result in patients achieving higher efficacy for viral suppression and a CD4+ count increase. Although the differences were statistically insignificant, the mean AST and ALT levels were marginally higher in efavirenz-treated groups than in dolutegravir-treated groups.

Factors Influencing Liver Abnormalities in Psoriatic Arthritis Patients: A Comprehensive Study.

The aim of this study was to establish the incidence of liver abnormalities in psoriatic arthritis patients and identify the factors that contributed to this condition. This is a longitudinal cohort study. Psoriatic arthritis (PsA) patients with liver enzymes abnormalities were identified. Our control group consisted of PsA patient from the same cohort who had no history of liver abnormalities. Factors associated with liver abnormalities were identified using univariate and multivariate analysis. A total of 247 of PsA patients were included and out of those, 99 developed liver enzymes abnormalities. The mean age of the patients was 56 years old (±13.5) with 56.1% female and 39.4% Indian descendants. The univariate logistic regression demonstrated that disease duration of PsA (OR=1.06, 95% CI=1.01 - 1.10, p=0.012), diabetes mellitus (OR=2.16, 95% CI=1.26 - 3.70, 0.005) and non-alcoholic fatty liver disease (NAFLD) (OR=3.90, 95% CI = 1.44 - 10.53, p=0.007) were associated with abnormal liver function in PsA patients. No association was found with both conventional synthetic disease-modifying antirheumatic drugs or biologics. Liver enzymes abnormalities in PsA patients were linked to disease duration, diabetes mellitus and NAFLD. For these high-risk populations, vigilant monitoring of liver function tests is vital for early detection and intervention.

Single center experience of IDH inhibitors in high-grade gliomas.

e14036 Background: IDH inhibitors have shown to improve progression free survival in low grade gliomas. Antitumor effect in high-grade gliomas is not well known, with conflicting views regarding the role of IDH mutations in high-grade gliomas and the potential for resistance to DNA-damage-inducing therapies. We present the outcomes of high-grade gliomas that were treated in our institution with IDH inhibitors. Methods: We performed a retrospective review of patients with gliomas treated with FDA approved IDH inhibitors (ivosidenib and enasidenib) in the past 5 years at our institution (January 1st 2019- January 1st 2024). Our search identified 32 patients of which 11 were identified as high-grade gliomas (both oligodendrogliomas and astrocytomas). Institutional Review Board PA17-0222 was used for this study. Results: Eleven high grade, IDH-mutant glioma patients treated with IDH inhibitors were identified with a median age at diagnosis of 31 years; 63.6% of these patients were men. Over 63% of patients were categorized as WHO grade 3 and 36.4% as grade 4 tumors. Over 63% of patients were astrocytoma (4 out of 7 patients with WHO grade 4 astrocytoma) while the rest were oligodendrogliomas. All patients underwent initial resection and had received radiation plus at least one prior line of systemic therapy prior to starting an IDH inhibitor. Over 72% were started on IDH-inhibitor therapy after 3 or more recurrences; previous lines of systemic therapy included temozolomide, bevacizumab, and lomustine. Five patients were treated with more than 1 cycle of IDH inhibitor, 2 patients with 8 cycles, and 1 patient with 18 cycles. Of the 11 treated patients, four had progression while on an IDH inhibitor, of which one patient died. IDH inhibitors were discontinued in two patients (due to headaches and abnormal liver enzymes). Median survival and progression free survival after IDH inhibitors were not reached. Conclusions: IDH inhibitors were started on patients with high-grade astrocytoma and oligodendroglioma after multiple recurrences and after receiving DNA-damage-inducing therapies. Prolonged responses were observed in 3 patients (one oligodendroglioma and two WHO grade 3 astrocytomas). Further investigation is needed to establish the role for IDH inhibitors in the treatment of high-grade gliomas.
