Syndecan 1 may slow the progression of subclinical atherosclerosis in patients with ankylosing spondylitis.

Background: Subclinical atherosclerosis may be seen at an early age of ankylosing spondylitis (AS). Syndecan 1 (S1) expression is increased in response to proinflammatory cytokine and inflammation. High S1 may reduce carotid atherosclerosis progression.

Proprotein convertase subtilisin/kexin type 9 is associated with atherosclerosis in patients with Behcet's disease.

Objectives: The incidence of cardiovascular disease is increased in patients with Behcet's disease (BD). Proprotein convertase subtilisin/kexin type 9 (PCSK9) causes the acceleration of atherosclerosis. We aimed to investigate whether there is a relationship between PCSK9 with carotid artery intima-media thickness (cIMT), a marker of subclinical atherosclerosis, and BD disease activity.

Can neutrophil-lymphocyte ratio predict mortality in acute non-variceal upper gastrointestinal bleeding?

Background: Acute non-variceal upper gastrointestinal bleeding (NVUGIB) is one of the common gastrointestinal problems and has a high mortality, especially in patients with poor hemodynamics. Therefore, treatment and follow-up should be managed dy-namically. Neutrophil-lymphocyte ratio (NLR) and platelet lymphocyte ratio (PLR) are fast workable, cheap, and easy to calculate he-matological parameters.

Correlation of myeloid-derived suppressor cells with C-reactive protein, ferritin and lactate dehydrogenase levels in patients with severe COVID-19.

The novel coronavirus disease 2019 (COVID-19) remains a global health emergency, and understanding the interactions between the virus and host immune responses is crucial to preventing its lethal effects. The expansion of myeloid-derived suppressor cells (MDSCs) in COVID-19, thereby suppressing immune responses, has been described as responsible for the severity of the disease, but the correlation between MDSC subsets and COVID-19 severity remains elusive. Therefore, we classified patients according to clinical and laboratory findings-aiming to investigate the relationship between MDSC subsets and laboratory findings such as high C-reactive protein, ferritin and lactate dehydrogenase levels, which indicate the severity of the disease.

Efficacy of convalescent plasma therapy in severe COVID-19 patients.

Introduction: The use of convalescent plasma (CP) transfusions is very valuable in the current COVID-19 outbreak, given that there are no specific preventive and therapeutic options.

Materials And Methods: 50 patients with severe COVID-19 disease treated with convalescent plasma transfusion were included in the study. The efficacy of CP and in which situations it was effective were investigated.

Apoptosis-induced T-cell lymphopenia is related to COVID-19 severity.

Increased levels of acute-phase reactants and lymphopenia are predictors of disease severity in coronavirus disease 2019 (COVID-19). This study aimed to investigate the role of apoptosis in the etiology of lymphopenia in patients with COVID-19. This multicentered, prospective, and case-control study was conducted with polymerase chain reaction (+) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients, and an age-gender-matched control group.

Hypomagnesemia Among Outpatient Long-Term Proton Pump Inhibitor Users.

Proton pump inhibitors (PPIs) are extensively prescribed drugs usually used for a long period. Recent reports linked PPI use with development of hypomagnesemia. However, there is still uncertainty regarding risk of hypomagnesemia in outpatients who were on long-term PPI use.
