Objective: Tumor necrosis factor-alpha (TNF-α) may play an important role in bipolar disorder (BD) pathogenesis. There is only one study about a relationship between TNF-α levels and cognitive impairments in BD. The aim of the present study was to see whether TNF-α, soluble P55 TNF receptor (sTNFR1), and soluble P75 TNF receptor (sTNFR2) levels in BD patients are different from controls and to investigate the relationships between the levels of TNF-α, sTNFR1, and sTNFR2 and the cognitive functions in euthymic BD patients and controls.

Methods: We assessed 54 BD type I patients and 18 controls by using a battery of neuropsychological tests. Serum TNF-α levels were measured using a commercially available enzyme-linked immunosorbent assay, whereas serum sTNFR1 and sTNFR2 levels were measured using a commercially enzyme-amplified sensitivity immunoassay kit.

Results: We found that levels of sTNFR1 and sTNFR2 in BD patients were different from controls. No difference was detected between the BD group and the control group for levels of TNF-α. TNF-α level was found to have a negative correlation with the delayed recall in RAVLT.

Conclusions: High levels of sTNFR1 and sTNFR2 in euthymic patients showed that it may support that proinflammatory process continues in euthymic period. This is the first study which showed increased sTNFR2 levels in euthymic period, which could be interpreted as a compensatory mechanism and again the first which deals with verbal memory.

Blood and urinary cytokine balance and renal outcomes at orthopaedic surgery.

Background: In patients undergoing orthopaedic trauma surgery, acute kidney injury (AKI) can develop post-operatively and is a major cause of increased mortality and hospital stay time. Development of AKI is associated with three main processes: inflammation, ischaemia-reperfusion injury (IRI) and hypoperfusion. In this study, we investigated whether ratios of urine and blood anti-inflammatory biomarkers and biomarkers of hypoperfusion, IRI and inflammation are elevated in patients who develop post-trauma orthopaedic surgery acute kidney injury (PTOS-AKI).

Objective: The aim of this study is to investigate the early prognostic efficacy of plasma soluble urokinase-type plasminogen activator receptor (suPAR), soluble tumor necrosis factor receptor 1 (sTNFR1), and soluble tumor necrosis factor receptor 2 (sTNFR2) in complicated acute kidney injury (AKI) in patients with coronavirus disease 2019 (COVID-19), and to analyze the relevant factors contributing to complicated AKI in these patients.

Methods: Patients with COVID-19 hospitalized at the Affiliated Baiyun Hospital of Guizhou Medical University from March 2022 to March 2024 were selected as study participants. A total of 589 patients met the inclusion and exclusion criteria, 68 patients complicated with AKI were classified as AKI group, and the remaining 521 cases were divided into proportion sampling method and randomly selected 200 samples, which were classified as non-AKI group.

Background: Frailty occurs at higher rates and younger ages among people with HIV (PWH) compared with the general population and is often attributed to chronic inflammation and subsequent immune exhaustion. We assessed how inflammatory biomarkers are associated with frailty among PWH.

Methods: The Centers for AIDS Research (CFAR) Network of Integrated Clinical Systems (CNICS) cohort is comprised of adult PWH in care at 10 sites, and harmonizes demographic, clinical, and patient-reported outcomes (PRO) data.

Regulation of plasma soluble receptors of TNF and IL-1 in patients with COVID-19 differs from that observed in sepsis.

Objectives: IL-1α/β and TNF are closely linked to the pathology of severe COVID-19 and sepsis. The soluble forms of their receptors, functioning as decoy receptors, exhibit inhibitory effects. However, little is known about their regulation in severe bacterial and viral infections, which we aimed to investigate in this study.

The effects of the MTHFR 677C>T (rs1801133) genetic variant on susceptibility and disability worsening in multiple sclerosis patients are mediated by homocysteine.

Background: Interactions between genetic and environmental variables contribute to the autoimmune inflammatory process in multiple sclerosis (MS). Elevated homocysteine levels, and vitamin D, vitamin B12, and folate deficiencies are some of the environmental factors associated with the pathogenesis of MS. Considering that the relationship between MTHFR 677C>T (rs1801133) genetic variant, homocysteine, and folate in patients with MS remains unclear and that their role were not extensively explored in the clinical course of the disease, we investigated whether this variant and plasma homocysteine and folate levels are associated with MS susceptibility, disability, disability progression, and inflammatory biomarkers.
