Microchimerism as Post-Transplant Marker of a Chronic Rejection Process.

The risk of losing a transplanted organ is high, and non-invasive markers to warn of this phenomenon are still being sought. We investigated the impact of post-transplant microchimerism on the function of the transplanted kidney. The study included 100 kidney transplant recipients, mostly women.

Improved survival in intensive care unit in severe COVID-19 associated with amantadine use - retrospective study.

Objectives: Possible immunomodulatory effect of amantadine in patients treated in intensive care unit (ICU), mostly among patients with brain injuries or vascular diseases was observed in several studies. The potential antiviral effect of amantadine against SARS-CoV-2 was discarded in clinical trials; however, immunomodulatory potential was not studied. The aim of the study was to investigate the effect of immunomodulatory amantadine therapy on mortality in patients with respiratory insufficiency due to COVID-19 requiring mechanical ventilation in ICU.

Programmed Cell Death-1/Programmed Cell Death-1 Ligand as Prognostic Markers of Coronavirus Disease 2019 Severity.

Current research proves that immune dysregulation is a common feature of coronavirus disease 2019 (COVID-19), and immune exhaustion is associated with increased disease mortality. Immune checkpoint molecules, including the programmed cell death-1 (PD-1)/PD-1 ligand (PD-L1) axis, may serve as markers of disease severity. Accordingly, in this study, we evaluated the expression of PD-1/PD-L1 in patients with COVID-19.

Nosocomial COVID-19 Infection and Severe COVID-19 Pneumonia in Patients Hospitalized for Alcoholic Liver Disease: A Case Report.

BACKGROUND COVID-19 is an infectious disease caused by SARS-CoV-2. It has spread rapidly through the world, endangering human life. The main target of COVID-19 is the lungs; however, it can involve other organs, including the liver.

Apnea testing using the oxygen insufflation method for diagnosis of brain death may compromise pulmonary function.

Introduction: The aim of our study was to compare the reliability and safety of the classical I-AT with the continuous positive airway pressure apnea test (CPAP-AT).

Material And Methods: In the group of 48 patients (group O), an I-AT was performed at the end of BD diagnostic procedures, and approximately 1-1.5h later CPAP-AT with 100% FiO and CPAP of 10cm HO, provided by ventilator in CPAP mode.
