Gut microbiome diversity and composition in individuals with and without extended-spectrum β-lactamase-producing Enterobacterales carriage: a matched case-control study in infectious diseases department.

Objective: Little is known about the effect of gut microbial and extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E) carriage, particularly in the general population. The aim of this study was to identify microbiota signatures uniquely correlated with ESBL-E carriage.

Methods: We conducted a case-control study among individuals seeking care at the Sexual Health Clinic or Department of Infectious and Tropical Diseases, Saint-Antoine Hospital, Paris, France.

Serum Axl predicts histology-based response to induction therapy and long-term renal outcome in lupus nephritis.

Axl is a receptor tyrosine kinase with important functions in immune regulation. We investigated serum levels of soluble (s)Axl in lupus nephritis (LN) in association with renal disease activity, tissue damage and treatment response. We surveyed 52 patients with International Society of Nephrology/Renal Pathology Society (ISN/RPS) class III/IV LN and 20 healthy controls.
