Estrogen signaling suppresses tumor-associated tissue eosinophilia to promote breast tumor growth.

Estrogens regulate eosinophilia in asthma and other inflammatory diseases. Further, peripheral eosinophilia and tumor-associated tissue eosinophilia (TATE) predicts a better response to immune checkpoint blockade (ICB) in breast cancer. However, how and if estrogens affect eosinophil biology in tumors and how this influences ICB efficacy has not been determined.

B cells and T cells abnormalities in patients with selective IgA deficiency.

Background: Selective IgA deficiency (SIgAD) is the most prevalent inborn errors of immunity with almost unknown etiology. This study aimed to investigate the clinical diagnostic and prognostic values of lymphocyte subsets and function in symptomatic SIgAD patients.

Methods: A total of 30 available SIgAD patients from the Iranian registry and 30 age-sex-matched healthy controls were included in the present study.

Single-pill sofosbuvir and daclatasvir for treating hepatis C in patients co-infected with human immunodeficiency virus.

Background: The current recommendation for treating hepatitis C virus (HCV) in HIV patients includes the combination of sofosbuvir (SOF) and daclatasvir (DCV). DCV should be used at different doses to compensate for interactions with antiretroviral therapy (ART). Up to three pills a day might be required which will significantly add to the pill burden of these patients.

Changes in liver fibrosis in patients with chronic hepatitis C after successful direct-acting antiviral therapy.

Introduction And Objectives: After successful treatment of hepatitis C virus (HCV) infection with direct-acting antivirals (DAAs), the stage of liver fibrosis decreases over time. Here, we aimed to assess the changes in the liver fibrosis stage using transient elastography (TE) after successful DAA therapy in HCV-infected cirrhotic patients who were referred to Shariati hospital from 2016 to 2017.

Material And Methods: In this observational cohort, all HCV-infected cirrhotic patients who were treated with a combination of sofosbuvir/daclatasvir, had sustained virologic response (SVR), and had undergone pre- and post-treatment TE, were enrolled.

Upper Normal Limits of Serum Alanine Aminotransferase in Healthy Population: A Systematic Review.

Unlabelled: BACKGROUND Measuring serum alanine aminotransferase (ALT) enzyme is a routine clinical test commonly used to evaluate abnormalities in the body in general, and in the liver function in particular. Higher ALT levels are associated with some metabolic disorders. The upper limit normal (ULN) is considered as a reliable threshold for the definition of high ALT.
