Background: COVID-19 continues to present challenges in the care of older adults with frailty and/or comorbidities and very old patients, who can be hospitalized severe despite full vaccination. Frailty is a heterogeneous syndrome characterized by an increased aging-related vulnerability due reduced physiological reserve function systemic organs, associated impairment activities daily living. Frail remain at elevated risk mortality from compared without frailty, some pre-existing factors such as malnutrition, prolonged bed rest, association aggravate SARS-CoV-2 infection. Furthermore, severity impact on long-term functioning patients surviving Persistent symptoms are another emerging problem post-vaccination phase pandemic, most suffer chronic which become debilitating affect routine. Aim this review: In complex relationship, evaluation vulnerable categories still matter high interest personalized plans based comprehensive geriatric assessment, tailored interventions; specific therapeutic algorithms among thus recommended order improve outcomes.

Potential therapeutic effects and nano-based delivery systems of mesenchymal stem cells and their isolated exosomes to alleviate acute respiratory distress syndrome caused by COVID-19

Regenerative Therapy, Год журнала: 2024, Номер 27, С. 319 - 328

Опубликована: Апрель 16, 2024

The severe respiratory effects of the coronavirus disease 2019 (COVID-19) pandemic have necessitated immediate development novel treatments. majority COVID-19-related fatalities are due to acute distress syndrome (ARDS). Consequently, this virus causes massive and aberrant inflammatory conditions, which must be promptly managed. Severe disorders, notably ARDS lung injury (ALI), may treated safely effectively using cell-based treatments, mostly employing mesenchymal stem cells (MSCs). Since high potential these was identified, a great deal research has been conducted on their use in regenerative medicine complementary medicine. Multiple investigations demonstrated that MSCs products, especially exosomes, inhibit inflammation. Exosomes serve critical function intercellular communication by transporting molecular cargo from donor receiver cells. derived exosomes (MSCs/MSC-exosomes) improve permeability, microbial alveolar fluid clearance, epithelial endothelial repair, according recent studies. This review focuses clinical studies involving MSCs/MSC-exosomes. We also investigated utilization Nano-delivery strategies for MSCs/MSC-exosomes anti-inflammatory agents enhance COVID-19 treatment.

Abstract Background Advancing age is a major risk factor for respiratory viral infections. The infections are often prolonged and difficult to resolve resulting hospitalizations mortality. recent COVID-19 pandemic has highlighted this as elderly subjects have emerged vulnerable populations that display increased susceptibility severity SARS-CoV-2. There an urgent need identify the probable mechanisms underlying protect against future outbreaks of such nature. Innate immunity first line defense viruses its decline impacts downstream immune responses. This because dendritic cells (DCs) macrophages key cellular elements innate system can sense respond by producing inflammatory mediators priming CD4 CD8 T-cell Results We investigated changes in responses SARS-CoV-2 function age. Our results using human PBMCs from aged, middle-aged, young indicate activation DCs monocytes response compromised with impairment most apparent pDCs where both aged middle-aged reduced secretion IL-29 confers protection also decreased subjects. In contrast, associated severe including CXCL-8, TREM-1 gene expression data pathways related host dependent decrease concomitant increase pathways.

Regulatory cytokines modulate early isotype-specific response associated with COVID-19 survival

Frontiers in Immunology, Год журнала: 2025, Номер 16

Опубликована: Апрель 24, 2025

Identifying immune markers driving early and effective antibody response in patients with severe coronavirus disease 2019 (COVID-19) is critical due to the threat of future pandemics, incomplete global vaccination, suboptimal booster coverage. Patients life-threatening acute respiratory syndrome 2 (SARS-CoV-2) infection are characterized by dysregulated thromboinflammation cytokine storm that could influence isotype virus-specific subsequent clinical outcome. We investigated association between COVID-19-related mortality dynamics, magnitude, relative avidity nucleoprotein (N), spike (S), receptor-binding domain (RBD)-specific IgM, IgA, IgG circulation. also assessed relationship responses patterns, as well systemic pulmonary markers. This multicenter study included COVID-19 hospitalized pandemic, classified survivors (n=62) non-survivors (n=17). developed indirect enzyme-linked immunosorbent assays (ELISAs) evaluate each using well-characterized outpatient (n=180) pre-pandemic cohorts (n=111). The pro-inflammatory interleukin (IL)-6 tumor necrosis factor (TNF)-α, regulatory IL-10, transforming growth (TGF)-β1, soluble receptor I (sTNFRI) levels were evaluated. ELISAs performed highly for all isotypes, although modest IgM-N. Non-survivors increased N-specific, but no S-specific, IgM IgA throughout course and, more notably, a delayed class switching IgG-S IgG-RBD compared survivors. No differences observed avidity. Survivors exhibited an proportional degree thromboinflammation, whereas showed those dissociated because their uncontrolled thromboinflammation.
