Histopathological features of multiorgan percutaneous tissue core biopsy in patients with COVID-19.

Aims: The global outbreak of COVID-19 has resulted in an increased mortality. However, whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can affect multiple organs is still unclear. In this study, postmortem percutaneous biopsies of multiple organs from deceased patients were performed to understand the histopathological changes caused by COVID-19.

Multicenter prospective study to validate a new transient elastography device for staging liver fibrosis in patients with chronic hepatitis B.

Objectives: To validate the operational and diagnostic performances of a new device for transient elastography (TE), FibroTouch, for liver fibrosis in patients with chronic hepatitis B (CHB).

Methods: In this prospective multicenter study, adult patients with CHB and valid liver pathological results were recruited to validate the operational and diagnostic performance of a TE device by FibroTouch for staging liver fibrosis.

Results: In total, 517 patients with histologically proven CHB were enrolled.

Clonal characteristics of paired infiltrating and circulating B lymphocyte repertoire in patients with primary biliary cholangitis.

Background: PBC is a prototypical autoimmune liver disease characterized by portal lymphoplasmacyte infiltration. ALD is a prototypical environment-driven disease, featured by mild lymphocyte infiltration. We hypothesize that B cells are more involved in the pathogenesis of PBC.

Pathological characteristics of liver biopsies in eight patients with hepatic epithelioid hemangioendothelioma.

We aim to investigate the pathological characteristics of liver biopsies and their implications for the prognosis of hepatic epithelioid hemangioendothelioma (HEHE). Clinical data of eight patients (5 male, 3 female) with HEHE were analyzed retrospectively. Expression of CD34, FVIII, AE1/AE3, Hepa-par1, GPC3, CK19 and the proliferation index marker Ki-67 were determined by immunohistochemical staining.
