AI Article Synopsis
- The study focuses on the sonographic characteristics of lymphoma that affects the liver, which is a less common but significant site for this type of cancer.
- It reviewed the sonographic findings of 23 patients with confirmed lymphoma, noting prevalent features like hepatomegaly, splenomegaly, and multiple small focal liver lesions.
- While sonography can aid in diagnosing liver infiltration by lymphoma, histologic confirmation is necessary due to the low specificity of the observed findings.
Article Abstract
Objective: The liver is one of the most frequent extranodal locations of non-Hodgkin lymphoma and Hodgkin disease. Nevertheless, lymphoma constitutes only 6% to 8% of focal lesions of the liver. Few studies have evaluated the sonographic patterns of lymphoma with liver involvement. The purpose of this study was to describe the sonographic features and to evaluate the accuracy of sonography for the diagnosis of lymphoma with liver infiltration.
Methods: The abdominal sonographic findings of 23 consecutive patients with histologically proven diagnosis of lymphoma with liver involvement were reviewed.
Results: The most prevalent sonographic features were hepatomegaly and splenomegaly. Abdominal lymphoadenopathies were identified in 34.8% of cases. Liver nodules were seen in half of patients, and the most frequent sonographic appearance was as multiple small focal lesions. Differences in sonographic patterns between high- and low-grade non-Hodgkin lymphoma were not seen. None of the patients with Hodgkin disease had liver nodules. Concordance between sonography and computed tomography for the diagnosis of focal liver lesions was observed.
Conclusions: Sonography may contribute to the diagnosis of liver infiltration by lymphoma. The presence of multiple focal liver lesions associated with splenomegaly and lymphoadenopathies should make us consider the diagnosis of lymphoma with liver involvement. Nevertheless, the low specificity of these findings requires histologic confirmation of lymphomatous infiltration of the liver.

The Hedgehog (Hh) signaling pathway is essential for maintaining homeostasis during embryogenesis and in adult tissues. In the liver, dysregulation of this pathway often leads to liver cancer development. Recent studies also suggest that disturbances in the Hh pathway can affect liver metabolism in healthy livers through interactions with other signaling pathways, such as the Wnt/β-catenin pathway.

Chlorpyrifos (CPF) is one of the most widely used organophosphorus pesticides all over the world. Unfortunately, long-term exposure to CPF may cause considerable toxicity to organisms. Some evidence suggests that the intestinal microbial community may be involved in regulating the toxicity of CPF.

parasites have a complex life cycle that transitions between mosquito and mammalian hosts, and undergo continuous cellular remodeling to adapt to various drastic environments. Following hepatocyte invasion, the parasite discards superfluous organelles for intracellular replication, and the remnant organelles undergo extensive branching and mature into hepatic merozoites. Autophagy is a ubiquitous eukaryotic process that permits the recycling of intracellular components.

Background: Microbiota-derived toxins indoxyl sulfate and hippuric acid were previously reported to be associated with altered pharmacokinetics of the immunosuppressant tacrolimus in liver transplant recipients, and ABC transporter proteins are likely to be involved in the transport of such substances, but the role has not been elucidated. The aim of this study was to assess the retention of indoxyl sulfate and hippuric acid in the plasma of liver transplantation subjects carrying different genotypes of and (changes in transporter activity due to genetic variation), and to explore whether genetic variation is involved in altering the relationship between microbe-derived toxins and tacrolimus pharmacokinetics.
Methods: Liver transplantation subjects treated with the immunosuppressive regimen tacrolimus, corticosteroids, and mycophyolate mofetil were included and divided into normal renal function group and chronic kidney disease group.
