AI Article Synopsis
- A study was conducted to analyze soluble interleukin-2 receptor (sIL-2R) levels in 54 newly diagnosed multiple myeloma patients compared to 60 healthy controls to assess clinical significance.* -
- Results showed that sIL-2R levels were significantly higher in multiple myeloma patients, particularly in those who did not achieve complete remission.* -
- Patients with high sIL-2R levels had shorter progression-free survival (15 months) compared to those with low levels (22 months), but overall survival rates were not significantly different between the two groups.*
Article Abstract
Objective: To investigate the expression and clinical significance of soluble interleukin-2 receptor(sIL-2R) in patients with multiple myeloma(MM).
Methods: 54 newly diagnosed MM patients in the Second Affiliated Hospital of Fujian Medical University from February 2020 to December 2021 were selected as the observation group, and 60 healthy people in our hospital in the same period were selected as the control group. The expression levels of sIL-2R in the serum of the two groups were detected by enzyme-linked immunosorbent assay. The differences of sIL-2R expression level among different clinical parameter groups in MM patients were compared. The clinical parameters include:gender, age, ISS stage, hemoglobin, albumin, serum creatinine, lactate dehydrogenase and β-microglobulin, blood calcium, bone marrow plasma cell ratio and treatment response. The relationship between sIL-2R expression level and progression-free survival(PFS) and overall survival(OS) in MM patients were analyzed.
Results: The expression of serum SIL-2R in MM patients was significantly higher than that in healthy control group (<0.05). The expression of sIL-2R in MM patients who did not achieve complete remission(CR) was significantly higher than those of CR patients (=0.037). There was no significant difference in the expression of serum sIL-2R between the groups of different sex, age, ISS stage, hemoglobin concentration, albumin content, serum creatinine level, lactate dehydrogenase level, the content of β-microglobulin, the concentration of blood calcium, and the proportion of bone marrow plasma cells(>0.05). The PFS of sIL-2R high expression group(15 months) was shorter than that of sIL-2R low expression group (22 months), which was significant difference (=0.041). But there was no significant difference in OS between sIL-2R high expression group and sIL-2R low expression group (=0.124). Univariate analysis results showed that the high expression of serum sIL-2R was associated with poor PFS in MM patients. Multivariate analysis results showed that the high expression of serum sIL-2R was still an independent adverse prognostic factor for PFS in MM patients, However, the expression of serum sIL-2R was not statistically significant in evaluating OS in MM patients by univariate and multivariate analysis.
Conclusion: The expression of serum sIL-2R in MM patients was significantly higher than that in healthy people. Serum sIL-2R is an independent prognostic factor of PFS in MM patients.

Article Synopsis
- Non-Hodgkin lymphoma (NHL) can resemble soft tissue tumors, making pre-biopsy diagnosis difficult; this study aimed to determine the effectiveness of serum soluble interleukin-2 receptor (sIL-2R) levels and MRI in diagnosing soft tissue NHL.* -
- Researchers analyzed 36 cases of confirmed soft tissue NHL alongside 48 control cases and found that combining MRI results (homogeneous appearance) and elevated sIL-2R levels effectively identified soft tissue NHL with high sensitivity and specificity.* -
- The study concluded that using both MRI and sIL-2R measurements together provides a reliable method for predicting soft tissue NHL, enhancing diagnostic accuracy compared to conventional tumor evaluations.*

Article Synopsis
- The study aims to explore how levels of soluble interleukin-2 receptor (SIL-2R), endothelial nitric oxide synthase (eNOS), and cluster of differentiation 93 (CD93) in cerebrospinal fluid and serum relate to the severity and outcome of viral encephalitis (VE) in children.
- 102 children diagnosed with VE were analyzed based on disease severity and prognosis, and compared to a control group of children without VE symptoms.
- Results showed that elevated levels of these markers are linked to worse outcomes, and combining these measures improves the prediction of prognosis compared to using them individually.
Non-linear relationship between soluble interleukin-2 receptor and prognosis of diffuse large B-cell lymphoma.

Despite an emphasis on the prognostic impact of serum soluble interleukin-2 receptor (sIL-2R) at diagnosis in patients with diffuse large B-cell lymphoma (DLBCL), whether the prognostic impact of elevated sIL-2R is linear remains unclear. To verify the presence of a non-linear association between sIL-2R level at diagnosis and overall survival (OS) in patients with newly diagnosed DLBCL, we conducted a multi-center, observational retrospective study. Among 488 analyzable patients, Cox proportional hazards modeling identified serum sIL-2R level at diagnosis as an independent predictor of OS.

Mature B-cell non-Hodgkin lymphoma (B-NHL) occurs due to uncontrolled B-lymphocyte clonal expansion. Cytokines can directly stimulate B-cell proliferation and prevent B-cell apoptosis. Dysregulation of cytokines may play an important role in the development of B-NHL by enhancing chromosomal translocation, which is the hallmark of B-NHL.

Background/aim: The soluble interleukin-2 receptor (sIL-2R) serve as a valuable biomarker for tumors in human patients, as its levels increase during the activation of T lymphocytes in clinical states such as inflammation, infection, and tumor. This study aimed to demonstrate that sIL-2R levels can be also elevated in dogs with tumors and evaluate its applicability as a diagnostic and prognostic factor in canine cancer patients.
Patients And Methods: Serum was collected from 6 healthy dogs and 34 dogs with solid tumors.
