liver function after liver transplantation

Cancer stem cells (CSCs) play pivotal roles in the growth, invasion, metastasis, chemo-resistance in malignant peripheral nerve sheath tumor (MPNST). The current characterization of CSCs in MPNST is not complete. Decorin is a critical regulator of microenvironment, but its expression and function in CSCs of MPNST has not been studied. In the current study, Decorin levels and its relationship with lung and liver metastasis were determined in clinical specimens. Decorin expression in CD133-positive or CD44-positive CSCs was analyzed by RT-qPCR on cytospun MPNST cells after flow cytometry-based cell sorting...

BACKGROUND: Eltrombopag has demonstrated efficacy in treating low platelet (PLT) levels, but it remains unclear whether eltrombopag can promote PLT engraftment after hematopoietic stem cell transplantation (HSCT). METHODS: Forty-one HSCT patients received eltrombopag 50 mg/d from +1 day until PLT >50 × 109 /L or 1 month after HSCT. Fifty-one patients in the same period received thrombopoietin (TPO) to promote PLT graft after HSCT and served as a control group...

Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening hematological disorder of immune dysregulation associated with significant challenges in diagnosis and management. Described as primary HLH secondary to genetic defects or more commonly secondary to infections, it can also occur secondary to malignancy, i.e., malignancy-associated hemophagocytic lymphohistiocytosis (M-HLH). A five-year-old male child presented with left cervical adenopathy and a high-spiking fever for two weeks. He had pallor, anasarca, multiple enlarged and matted cervical lymph nodes, respiratory distress, and hepatomegaly...

BACKGROUND AND AIMS: Hepatic ischemia-reperfusion injury (HIRI) is a prevalent complication of liver transplantation, partial hepatectomy, and severe infection, necessitating the development of more effective clinical strategies. Receptor activity-modifying protein 1 (RAMP1), a member of the G protein-coupled receptor adapter family, has been implicated in numerous physiological and pathological processes. The study aimed to investigate the pathogenesis of RAMP1 in HIRI. METHODS: We established a 70% liver ischemia-reperfusion model in RAMP1 knockout (KO) and wild-type mice...

BACKGROUND: Helsmoortel-Van der Aa syndrome is a neurodevelopmental disorder in which patients present with autism, intellectual disability, and frequent extra-neurological features such as feeding and gastrointestinal problems, visual impairments, and cardiac abnormalities. All patients exhibit heterozygous de novo nonsense or frameshift stop mutations in the Activity-Dependent Neuroprotective Protein (ADNP) gene, accounting for a prevalence of 0.2% of all autism cases worldwide. ADNP fulfills an essential chromatin remodeling function during brain development...

Objective: To analyze the clinical manifestations, pathology, and gene variant characteristics in children with progressive familial intrahepatic cholestasis type 3 (PFIC3). Methods: This retrospective study assessed the clinical manifestations, pathological features, gene variants, and prognosis data of 11 children with PFIC3 hospitalized in the Department of Hepatology, Fifth Medical Center, PLA General Hospital, from January 2015 to December 2022. Panel or whole exome sequencing was performed on the probands, followed by Sanger sequencing for verification within the family...

BACKGROUND: Systemic lupus erythematosus (SLE) and Wilson's disease (WD) are both systemic diseases that can affect multiple organs in the body. The coexistence of SLE and WD is rarely encountered in clinical practice, making it challenging to diagnose. CASE REPORT: We present the case of a 9-year-old girl who initially presented with proteinuria, haematuria, pancytopenia, hypocomplementemia, and positivity for multiple autoantibodies. She was diagnosed with SLE, and her blood biochemistry showed elevated liver enzymes at the time of diagnosis...

OBJECTIVES: Trimethylamine N-oxide (TMAO) is a gut bacteria mediated liver metabolite of dietary betaine, choline, and carnitine which is excreted by glomerular filtration. We studied whether TMAO is associated with cardiovascular disease (CVD) in patients with chronic kidney disease (CKD). METHODS: Among 478 patients with CKD stage G2 (n = 104), G3a (n = 163), G3b (n = 123), and G4 (n = 88), we studied the association between fasting plasma concentrations of TMAO, choline or betaine at baseline and kidney function, prevalent CVD and future renal outcomes during a mean follow-up of 5...

BACKGROUND: In organ transplantation, ischemia, and reperfusion injury (IRI) is considered as an inevitable event and the major contributor to graft failure. Ischemia-free liver transplantation (IFLT) is a novel transplant procedure that can prevent IRI and provide better transplant outcomes. However, a large animal model of IFLT has not been reported. Therefore, we develop a new, reproducible, and stable model of IFLT in pigs for investigating mechanisms of IFLT in IRI. METHODS: Ten pigs were subjected to IFLT or conventional liver transplantation (CLT)...

Post-transplant complications reduce allograft and recipient survival. Current approaches for detecting allograft injury non-invasively are limited and do not differentiate between cellular mechanisms. Here, we monitor cellular damages after liver transplants from cell-free DNA (cfDNA) fragments released from dying cells into the circulation. We analyzed 130 blood samples collected from 44 patients at different time points after transplant. Sequence-based methylation of cfDNA fragments were mapped to patterns established to identify cell types in different organs...

BACKGROUND: The shortage of transplant organs remains a severe global issue. Normothermic machine perfusion (NMP) has the potential to increase organ availability, yet its efficacy is hampered by the inflammatory response during machine perfusion. METHODS: Mouse liver IRI models, discarded human liver models, and porcine marginal liver transplantation models were utilized to investigate whether FXR activation could mitigate inflammation-induced liver damage. FXR expression levels before and after reperfusion were measured...

BACKGROUND & AIMS: Cystic Fibrosis (CF) liver disease progresses to liver failure requiring transplantation in about 3 % of patients, 0.7 % of CF patients are post liver transplant. The prognosis of CF has improved with the introduction of elexacaftor/tezacaftor/ivacaftor (ETI). Due to the paucity of data and concerns regarding interactions with immunosuppressive drug regimens, there is no general consensus on use of ETI post liver transplantation. The aim of this review is to report the safety and efficacy of ETI in CF patients who underwent liver transplantation...

Partial hepatectomy is an essential surgical technique used to treat advanced liver diseases such as liver tumors, as well as for performing liver transplants from living donors.However, postoperative complications such as bleeding, abdominal adhesions, wound infections, and accelerated liver regeneration pose significant challenges and increase morbidity and mortality rates.We have developed a self-repairing mixed hydrogel (O5H2/Cu2+/SCCK) containing bioactive cell factors (SCCK) derived from Human Umbilical Cord Mesenchymal Stem Cells (HUMSCs) treated with the traditional Chinese remedy Tanshinone IIA (TSA)...

BACKGROUND & AIMS: The shortage of donor livers hinders the development of liver transplantations. This study aimed to clarify the poor outcomes of functioned marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) on transplantation with FMLs. METHODS: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FMLs were compared to demonstrate the negative impact of FMLs in liver transplantation patients...

BACKGROUND: Highly active antiretroviral therapy (HAART) has been able to improve the immune system function and survival of human immunodeficiency virus (HIV) patients. However, Patients coinfected with HIV and hepatitis B virus (HBV) are more likely to develop end-stage liver disease (ESLD) than those infected with HBV alone. Consequently, liver transplantation is often required for these patients. This study evaluates the outcomes of orthotopic liver transplantation (OLT) of HIV-HBV coinfected patients in China...

INTRODUCTION: Most pregnancies in women after a kidney transplant result in a live birth, but kidney functions should be stable for one year before conception. For immunosuppression modification occurring before pregnancy, azathioprine is used because it is considered safe for major congenital malformations during pregnancy. However, there may be an association between exposure to azathioprine during pregnancy and the onset of an unusual, early and severe form of intrahepatic cholestasis...

BACKGROUND: Due to the lack of published literature about treatment of refractory hepatopulmonary syndrome (HPS) after liver transplant (LT), this case adds information and experience on this issue along with a treatment with positive outcomes. HPS is a complication of end-stage liver disease, with a 10%-30% incidence in cirrhotic patients. LT can reverse the physiopathology of this process and restore normal oxygenation. However, in some cases, refractory hypoxemia persists, and extracorporeal membrane oxygenation (ECMO) can be used as a rescue therapy with good results...

BACKGROUND: Liver transplantation (LT) is a life-saving procedure for patients with end-stage liver disease and has become the standard and most effective treatment method for these patients. There are many indications for LT that vary between countries and settings. The outcome of LT depends on the available facilities and surgical expertise, as well as the types of liver graft donors available. AIM: To assess the clinical characteristics of patients from Bahrain who underwent LT overseas, and analyze factors affecting their survival...

BACKGROUND: Acute rejection (AR) after liver transplantation (LT) remains an important factor affecting the prognosis of patients. CD8+ T cells are considered to be important regulatory T lymphocytes involved in AR after LT. Our previous study confirmed that autophagy mediated AR by promoting activation and proliferation of CD8+ T cells. However, the underlying mechanisms regulating autophagy in CD8+ T cells during AR remain unclear. METHODS: Human liver biopsy specimens of AR after orthotopic LT were collected to assess the relationship between JNK and CD8+ T cells autophagy...

PURPOSE: Ex vivo liver resection and autotransplantation (ERAT) can be used to treat locally advanced tumors that are conventionally unresectable. Because the procedure is rare, there are very few reports in the literature. Recently, we performed ERAT for two cases of cholangiocarcinoma invading caudate lobe, the retrohepatic vena cava and hepatic veins, and investigated technical variations of this procedure. METHODS: One patient was a 57-year-old man with liver caudate lobe metastasis from cholangiocarcinoma after pancreaticoduodenal resection five years ago, and the other patient was a 68-year-old man with caudate lobe cholangiocarcinoma...
