Impact of immunosuppression on infection in Spain.

Introduction: Immunosuppression (IS) determines a higher risk of disease severity from LM) infection.

Methods: We examined the epidemiology of IS in all patients hospitalized with LM in Spain from 2000 to 2021 in the National Registry of Hospital Discharges. IS was defined by liver disease (LD), diabetes mellitus (DM), chronic kidney disease (CKD), solid organ transplantation (SOT), bone marrow transplantation (BMT), primary immunodeficiencies (ID), systemic autoimmune diseases (SAD), solid organ neoplasms (SON), and hematological neoplasms (HN).

Pregnancy-related listeriosis in Spain.

Background: Pregnant women are at high risk of acquiring listeriosis, resulting in severe fetal and neonatal outcomes.

Methods: All hospitalizations with a listeriosis diagnosis in pregnant women (obstetric listeriosis) and/or newborns (neonatal listeriosis) in Spain from 2000 to 2021 were examined using the National Registry of Hospital Discharges, employing ICD-9 and -10 coding lists.

Results: A total of 540 and 450 hospital admissions for obstetric listeriosis and neonatal listeriosis were identified, respectively, with 146 adverse fetal-neonatal outcomes (miscarriage, fetal loss, stillbirth, and neonatal death).
