CD4 lymphocyte count and CD4/CD8 ratio in elderly long-term care patients with oropharyngeal dysphagia: comparison between oral and tube enteral feeding

Dysphagia
Arthur LeibovitzB Habot

Abstract

Many institutionalized elderly patients are at risk of undernutrition as a result of oropharyngeal dysphagia (OD) that possibly affects their immunological status. Tube enteral fed (TEF) patients on controlled intake of nutrients enables us to evaluate the effect of inadequate nutrition on the immune system in the orally fed elderly with OD. The aim of our study was to compare CD4 lymphocyte count and CD4/CD8 ratio between these two differently fed groups. Twenty-eight orally fed patients with OD in the Functional Outcome Swallowing Scale (FOSS) stage 2 (group A) and 17 TEF subjects (group B) were studied. CD4 and CD8 counts were determined by flow cytometry. Nutritional markers (albumin, hemoglobin, and basal metabolic index) were recorded for each group. The Charlson index was used for comparison of comorbidity between the two patient groups. The average count of CD4 lymphocytes was significantly lower in group A than in group B (754 +/- 365 vs. 1032 +/- 404 cells/ml, p < 0.01). Six patients in group A (21%) had a CD4 count of less than 400 cells/ml (lower threshold) while all the patients in group B had a CD4 count of over 500 cells/ml (p < 0.001). The CD4/CD8 average ratio was also significantly lower in group A (p < 0.008)...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
