Macrophage colony-stimulating factor receptor/CD115 non-classical monocytes are expanded in systemic lupus erythematosus and associated with lupus nephritis.

Objective: In systemic lupus erythematosus (SLE), the non-classical monocyte compartment is expanded, but its phenotype and association with clinical disease manifestations have not been explored.

Method: Monocyte subsets from 39 SLE patients, 32 healthy age-matched controls, and 16 patients from a disease control (autoimmune connective tissue disease other than SLE) were determined based on CD14 and CD16 surface expression. Cell surface expression of the receptors for macrophage colony-stimulating factor (M-CSF) (CD115) and granulocyte-macrophage colony-stimulating factor (GM-CSF) (CD116), as well as 6-Sulpho LacNAc (slan), were analysed by flow cytometry.

Fetal and Placental Causes of Elevated Serum Alpha-Fetoprotein Levels in Pregnant Women.

The most common association related to alpha-fetoprotein (AFP) is fetal neural tube defect (NTD), and indeed, this is where the international career of this protein began. In times when ultrasonography was not yet technically advanced, the detection of high levels of AFP in maternal serum (MS-AFP) and amniotic fluid was the basis for suspecting neural tube defects. In cases where there was no confirmation of NTD, other causes were sought.

Role of Alpha-Fetoprotein (AFP) in Diagnosing Childhood Cancers and Genetic-Related Chronic Diseases.

Alpha-fetoprotein (AFP) is a protein commonly found during fetal development, but its role extends beyond birth. Throughout the first year of life, AFP levels can remain high, which can potentially mask various conditions from the neurological, metabolic, hematological, endocrine, and early childhood cancer groups. Although AFP reference values and clinical utility have been established in adults, evaluating AFP levels in children during the diagnostic process, treatment, and post-treatment surveillance is still associated with numerous diagnostic pitfalls.

SARS CoV-2 infection as a risk factor of preeclampsia and pre-term birth. An interplay between viral infection, pregnancy-specific immune shift and endothelial dysfunction may lead to negative pregnancy outcomes.

Background: Since SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) was first identified as the cause of Coronavirus disease 19 (COVID-19) it has caused over 649,147,421 infections and over 6,730,382 deaths worldwide. SARS-CoV-2 presents higher infectivity than other coronaviridae (MERS-CoV and SARS-CoV). Pregnant patients, according to previous studies are at high risk of severe COVID-19 course and negative pregnancy outcomes (pre-term birth, low birth weight, preeclampsia, operative delivery and ICU admission with need for mechanical ventilation).

Low-Salt Diet Attenuates B-Cell- and Myeloid-Cell-Driven Experimental Arthritides by Affecting Innate as Well as Adaptive Immune Mechanisms.

A link between high sodium chloride (salt) intake and the development of autoimmune diseases was previously reported. These earlier studies demonstrated exacerbation of experimental autoimmune encephalomyelitis and colitis by excess salt intake associated with Th17- and macrophage-mediated mechanisms. Little is known about the impact of dietary salt intake on experimental arthritides.
