Introduction: To our knowledge, the diagnostic value of the sP-Selectin level in the diagnosis of COVID-19 disease has not yet been investigated. In this study, we aimed to assess this by evaluating the relationship between sP-Selectin level and the clinical severity of COVID-19 infections.
Methods: A total of 80 patients (50 with mild to moderate and 30 with severe COVID-19 pneumonia), and 60 non-symptomatic healthy volunteers participated in the study. Following serum isolation, sP-Selectin levels were assessed by Enzyme-Linked Immunosorbent Assay (ELISA) method.
Results: The serum sP-Selectin level was 1.7 ng/ml in the control group (1-3.78); 6.24 ng/ml (5.14-7.23) in mild-to-moderate pneumonia group; and 6.72 ng/ml (5.36-8.03) in the severe pneumonia group. Serum sP-Selectin levels in both mild-to-moderate pneumonia and severe pneumonia groups were found to be higher than the control group, with statistical significance (p = 0.0001 and p = 0.0001, respectively). Receiver operating characteristic analysis (ROC) showed greater area under the curve (AUC) for the serum sP-Selectin levels of the COVID-19 patients (AUC = 0.913, 95% CI = 0.857-0.969; p = 0.0001). The serum sP-Selectin level was found to be 97.5% sensitive and 80% specific at 4.125 ng/ml level for diagnosis (p = 0.0001). The serum sP-Selectin level was found to be 76.9% sensitive and 51.9% specific at the level of 6.12 ng/ml (p = 0.005) to predict the need for intensive care treatment.
Conclusion: This study showed that sP-Selectin can be used as a valuable biomarker in both diagnosing and predicting the need for intensive care treatment of COVID-19 infection.

Introduction: Type 2 diabetes (T2D) is a prevalent metabolic disorder linked to chronic inflammation and endothelial dysfunction, which contributes to the development of microvascular complications (MVCs) such as diabetic retinopathy (DR) and diabetic neuropathy (DN). Genetic factors, including variations in the ABO gene, may influence these complications. This study aimed to investigate the association between the ABO rs2073823 polymorphism and the risk of MVCs in patients with T2D, as well as its impact on inflammatory biomarkers, endothelial markers, and lipid profiles.

This study aimed to analyze the relationship between cutaneous microcirculation reactivity, retinal circulation, macrocirculation function, and specific adhesion molecules in young patients with uncomplicated type 1 diabetes. Fifty-five patients with type 1 diabetes mellitus (T1DM), aged 8 to 18 years, were divided into subgroups based on skin microcirculation reactivity. The cutaneous microcirculatory vessels were considered reactive if post-test PORH coverage increased compared to pre-test coverage.

Objectives: There is a growing need to understand the potential role of soluble platelet selectin (sP-selectin) in sustained endothelial activation through increased levels of soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular adhesion-1 (sVCAM-1) in people living with HIV (PLWH) on highly active antiretroviral therapy (HAART).
Methodology: This was a cross-sectional study involving PLWH on HAART (n = 55), in comparison to PLWH not on treatment (HAART-naïve) (n = 29), and (iii) HIV negative controls (n = 48) from the Mankweng area in the Limpopo province, South Africa. We quantified serum levels of sP-selectin, together with sICAM-1 and sVCAM-1.

Venous thromboembolism (VTE) is the third most common cardiovascular disease. Clonal haematopoiesis (CH) is linked to cardiovascular disease risk, but its potential association with VTE remains poorly understood. We assessed the prevalence of CH in patients with recurrent VTE (n = 107; median age [IQR] 57 [48-63] years, 44.

Article Synopsis
- - Type 2 diabetes mellitus (T2DM) is a widespread health problem linked to chronic inflammation, which worsens the disease and leads to complications like cardiovascular issues.
- - A study involving 522 diabetes patients compared the effects of insulin and metformin on inflammatory markers and complications, revealing that insulin users had significantly higher rates of microvascular problems like retinopathy and neuropathy compared to those on metformin.
- - Results showed that insulin treatment lowered certain inflammatory markers (TNF-α and IL-6) but increased adhesion molecules (sE-selectin and sP-selectin), while metformin showed different inflammatory profiles, suggesting that treatment choices could influence disease progression differently.
