Respir Investig 2024; 62:223-230. [PMID: 38218098 DOI: 10.1016/j.resinv.2023.12.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Revised: 12/13/2023] [Accepted: 12/22/2023] [Indexed: 01/15/2024]
Abstract
BACKGROUND Interleukin-34 (IL-34) is a hematopoietic cytokine and a ligand of colony-stimulating factor 1 receptor (CSF-1R). Numerous studies have demonstrated that IL-34 is involved in several inflammatory diseases. Nevertheless, the role of IL-34 is obscure in community-acquired pneumonia (CAP) patients. This research aimed to assess the associations of serum IL-34 with severity and prognosis in CAP patients through a longitudinal study. METHODS CAP patients and healthy volunteers were recruited. Peripheral blood samples were collected. Serum IL-34 and inflammatory cytokines were tested by enzyme linked immunosorbent assay (ELISA). Demographic characteristics and clinical information were acquired through electronic medical records. RESULTS Serum IL-34 was elevated in CAP patients compared with healthy volunteers. The content of serum IL-34 was gradually upregulated with increased CAP severity scores. Mixed logistic and linear regression models suggested that serum IL-34 elevation was associated with increased PSI and SMART-COP scores. Correlative analysis found that serum IL-34 was positively correlated with inflammatory cytokines among CAP patients. A longitudinal study indicated that higher serum IL-34 at admission elevated the risks of mechanical ventilation and death during hospitalization. Serum IL-34 had a higher predictive capacity for death than CAP severity scores. CONCLUSION There are prominently positive dose-response associations between serum IL-34 at admission with the severity and poor prognosis, suggesting that IL-34 is implicated in the occurrence and development of CAP. Serum IL-34 may serve as a biomarker to forecast disease progression and poor prognosis in CAP patients.

Karasu M, Bolayır HA. Cut-off value for interleukin-34 as an additional potential inflammatory biomarker for estimation of slow coronary flow risk. BMC Cardiovasc Disord 2024; 24:2. [PMID: 38166811 PMCID: PMC10762812 DOI: 10.1186/s12872-023-03677-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 12/17/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Inflammatory markers may provide insights into the underlying mechanisms of slow coronary flow (SCF), including subclinical atherosclerosis and endothelial dysfunction. Interleukin-34 (IL-34), known for its role in immuno-inflammatory diseases, might hold significance in SCF. We aimed to explore the potential association between IL-34 and SCF in patients undergoing diagnostic elective coronary angiography. METHODS This observational, cross-sectional study enrolled 256 participants: 124 with SCF and 132 with normal coronary flow (NCF). All participants had undergone outpatient coronary angiography for suspected coronary artery disease. SCF assessment employed the TIMI frame count (TFC) for quantifying coronary flow rate. RESULTS SCF patients exhibited significantly elevated TFC in all three major coronary arteries compared to controls (p < 0.05). IL-34 displayed a noteworthy positive correlation with average TFC [for all participants: r = 0.514, p < 0.001; for SCF patients: r = 0.526, p < 0.001; for normal controls: r = -0.288, p > 0.05]. Similarly, high-sensitivity C-reactive protein (hsCRP) showed a significant and positive relationship with average TFC [for all participants: r = 0.504, p < 0.001; for SCF patients: r = 0.558, p < 0.001; for normal controls: r = -0.148, p > 0.05]. SCF patients presented coronary arteries of larger size compared to controls. CONCLUSION Mean coronary diameter and IL-34 emerged as independent predictors of SCF. Additionally, hsCRP, mean coronary diameter, and IL-34 exhibited a positive correlation with mean TFC values. IL-34 appears to be a more effective indicator than hsCRP in SCF patients.

Abstract
Protein tyrosine phosphatase receptor-ζ1 (PTPRZ1) is a transmembrane
tyrosine phosphatase receptor highly expressed in embryonic stem cells. In the
present work, gene expression analyses of Ptprz1−/− and Ptprz1+/+ mice endothelial cells and hearts pointed to
an unidentified role of PTPRZ1 in heart development through the regulation of
heart-specific transcription factor genes. Echocardiography analysis in mice
identified that both systolic and diastolic functions are affected in Ptprz1−/− compared with Ptprz1+/+ hearts, based on a dilated left
ventricular (LV) cavity, decreased ejection fraction and fraction shortening,
and increased angiogenesis in Ptprz1−/−
hearts, with no signs of cardiac hypertrophy. A zebrafish ptprz1−/− knockout was also generated and exhibited
misregulated expression of developmental cardiac markers, bradycardia, and
defective heart morphogenesis characterized by enlarged ventricles and defected
contractility. A selective PTPRZ1 tyrosine phosphatase inhibitor affected
zebrafish heart development and function in a way like what is observed in the
ptprz1−/− zebrafish. The same
inhibitor had no effect in the function of the adult zebrafish heart, suggesting
that PTPRZ1 is not important for the adult heart function, in line with data
from the human cell atlas showing very low to negligible PTPRZ1 expression in
the adult human heart. However, in line with the animal models, Ptprz1 was expressed in many different cell types in
the human fetal heart, such as valvar, fibroblast-like, cardiomyocytes, and
endothelial cells. Collectively, these data suggest that PTPRZ1 regulates
cardiac morphogenesis in a way that subsequently affects heart function and
warrant further studies for the involvement of PTPRZ1 in idiopathic congenital
cardiac pathologies. NEW & NOTEWORTHY Protein tyrosine phosphatase receptor
ζ1 (PTPRZ1) is expressed in fetal but not adult heart and seems
to affect heart development. In both mouse and zebrafish animal models, loss of
PTPRZ1 results in dilated left ventricle cavity, decreased ejection fraction,
and fraction shortening, with no signs of cardiac hypertrophy. PTPRZ1 also seems
to be involved in atrioventricular canal specification, outflow tract
morphogenesis, and heart angiogenesis. These results suggest that PTPRZ1 plays a
role in heart development and support the hypothesis that it may be involved in
congenital cardiac pathologies.

Abstract
BACKGROUND Recent data reveal that interleukin-34 (IL-34) can drive inflammatory response, thereby participating in the pathogenesis of inflammatory diseases. However, the potential effect of IL-34 in acute ischemic stroke (AIS) remains unknown. The purpose of this study was to explore whether the levels of serum IL-34 were correlated with clinical severity or prognosis in AIS patients. METHODS In this prospective cohort study, serum IL-34 levels were detected in 150 healthy controls and 155 AIS patients. Univariate and multivariate logistic regression analysis were conducted to investigate the effect of IL-34 on the diagnosis and prognosis of AIS. ROC curve was utilized to evaluate predictive values for IL-34. RESULTS Serum IL-34 levels at admission were significantly higher in AIS patients than those in the healthy controls. Univariate and multivariate logistics regression analysis showed that IL-34 was an independent predictor of occurrence and functional outcome of AIS. The ROC curve demonstrated that IL-34 had a good predictive effect on the diagnosis and prognosis of AIS. CONCLUSIONS IL-34 can be used as a novel and independent diagnostic and predicting prognostic biomarker in AIS.

Decreased Levels of Serum IL-34 Associated with Cognitive Impairment in Vascular Dementia. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6793860. [PMID: 34095310 PMCID: PMC8163526 DOI: 10.1155/2021/6793860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/16/2021] [Revised: 05/05/2021] [Accepted: 05/13/2021] [Indexed: 12/04/2022]
Abstract
Objective Interleukin- (IL-) 34 is a new type of cytokine with neuroprotective effects discovered in recent years. However, the relationship between IL-34 and vascular dementia (VaD) has not yet been elucidated. The purpose of this study is to determine whether IL-34 is involved in cognitive impairment of VaD. Methods From January 2017 to December 2020, 84 VaD patients and 60 healthy controls who attended Qingpu Branch of Zhongshan Hospital were prospectively included in the study. Once included in the study, demographic features of all research subjects are collected. They include age, gender, education, white blood cells (WBC), neutrophil, lymphocyte, systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), triglycerides (TG), and total cholesterol (TC). Meanwhile, the Montreal Cognitive Assessment (MoCA) scale was used to assess the cognitive function of participants. The serum IL-34 level was determined by enzyme-linked immunosorbent assay (ELISA). Results There was no significant difference between the demographic features of VaD patients and healthy controls (p > 0.05). However, the serum IL-34 levels of VaD patients and healthy controls are 27.6 ± 3.9 pg/ml and 41.8 ± 6.0 pg/ml, respectively, and there is a significant statistical difference between them (p < 0.001). The results of bivariate correlation analysis showed that serum IL-34 levels were significantly positively correlated with MoCA scores (r = 0.371, p = 0.023). Further regression analysis showed that IL-34 was still correlated with MoCA after adjusting for demographic features (β = 0.276, p = 0038). Conclusions Serum IL-34 levels in VaD patients were significantly reduced, which may be an independent predictor of cognitive impairment in VaD patients.

Abstract
The prognostic capacities of nutritional status and inflammation in patients with acute myocardial infarction (AMI) have attracted increasing interest. However, the combined usefulness of the Controlling Nutritional Status (CONUT) score and neutrophil-to-lymphocyte ratio (NLR) in predicting adverse outcomes has not been investigated. The aim of our study was to investigate the relationship between the CONUT score and the NLR in patients with AMI and assessing the potential of these factors as prognostic markers.In this retrospective study, we reviewed the medical records of consecutive patients aged 65 years or older who were diagnosed with AMI and who underwent primary coronary intervention. We assessed the nutritional and inflammatory statuses using the CONUT score and the NLR, respectively. The NLR and CONUT score in the major adverse cardiovascular event (MACE) (+) patients were significantly higher than those in the MACE (-) patients. The areas under the receiver operating characteristic curves of the NLR and CONUT score were 0.71 and 0.77, respectively. The Kaplan-Meier analysis showed that patients with a high NLR (≥6.07) and CONUT score (≥3.5) had the worst prognoses. The multivariate Cox proportional hazards analyses suggested that the CONUT score was an independent predictor.The CONUT score was proven to be a significant prognostic factor of clinical outcomes in patients with AMI. However, further research in this area is needed to more fully understand the relationship among nutritional status, inflammation, and cardiovascular diseases, which might help reduce MACEs in patients with AMI.

Abstract
Although an elevated neutrophil to lymphocyte ratio (NLR) has been associated with the adverse outcomes of coronary artery disease (CAD), less is known about its prognostic value among patients with low high-sensitivity C-reactive protein (hs-CRP) levels. We enrolled 2,591 consecutive patients with stable CAD who underwent elective percutaneous coronary intervention (PCI) and had available data on preprocedural hs-CRP and NLR between 2000 and 2016. Of these patients, 1,951 with low-grade hs-CRP levels (< 2.0 mg/L) were divided into quartiles based on the NLR values. The primary endpoint was a composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke after the index PCI. Clinical follow-up data were obtained up to 5 years. The median NLR was 1.9 (interquartile range: 1.5-2.5). During the follow-up, 102 events occurred (5.2%), with a cumulative incidence that was significantly higher in the highest NLR group than in the other groups (log-rank, P = 0.02). After adjusting for the other cardiovascular risk factors, the risk for the primary endpoint was significantly higher for the highest than in the lowest NLR group (HR 1.97, 95% CI 1.09-3.54, P = 0.02). Increasing NLR as a continuous variable was associated with the incidence of adverse cardiovascular events (HR 1.85 per log 1 NLR increase, 95% CI 1.19-2.88, P = 0.007). In conclusion, the adverse long-term clinical outcomes of CAD patients with low-grade hs-CRP levels has been independently predicted by increased NLR level. NLR could be useful for risk stratification of CAD patients with increased inflammatory marker levels.
