Social support and C-reactive protein in a Québec population cohort of children and adolescents.

Robust evidence exists for the health-enhancing benefits of social support in adults. Inflammatory processes are thought to be an important mechanism linking social support and health risk. Less is kn... Data from the population-representative 1999 Quebec Child and Adolescent Health and Social (QCAHS) survey were analyzed. Youth aged 9, 13, and 16 years (N = 3613) and their parents answered questions ... Higher social support was significantly associated with lower hs-CRPlog, after controlling for age, sex, body mass index (BMI Z-score), medication use, puberty, ethnoracial status (French-Canadian), s... Greater social support was linked to lower chronic low-grade inflammation in a large sample of children and adolescents. Effect sizes were small and consistent with prior findings in the adult literat...

Impact of Human Genetic Variation on C-Reactive Protein Concentrations and Acute Appendicitis.

Acute appendicitis is one of the most common abdominal emergencies worldwide. Both environmental and genetic factors contribute to the disease. C-reactive protein (CRP) is an important biomarker in th... CRP concentrations in serum of appendicitis patients (n = 325) were measured. Appendicitis was categorized as complicated/uncomplicated and gangrenous/non-gangrenous. Imputed SNP data (n = 287) were g... Thirteen percent of significant CRP quantitative trait loci (QTLs) that were previously identified in a large cohort of healthy individuals were replicated in our small patient cohort.

The relation between C-reactive protein and serum amyloid A in patients with autoinflammatory diseases.

Autoinflammatory diseases are rare disorders of the innate immune system characterized by fever and other signs of inflammation. A feared complication of autoinflammatory diseases is the development o... The aim of this research is to evaluate the possible relation between CRP and SAA.... A retrospective cohort of patients with autoinflammatory diseases (n = 99) where SAA and CRP blood testing was performed in the period between 2015 and 2021 in the University Medical Centre in Groning... CRP and SAA have a high correlation (rho = 0.755, p < 0.001). A CRP value below 0.45 mg/L results in 100% sensitivity for SAA below 4 mg/L. CRP below 5 mg/L is a good predictor of SAA below 4 mg/L wit... There was a significant correlation between CRP and SAA in our retrospective cohort. CRP levels below 5 mg/L proved to be highly predictive of SAA levels below 4 mg/L. This may not be true for patient...

Leukocytosis and C-Reactive Protein Levels as Indicators of Infection in Children With Diabetic Ketoacidosis.

Diabetic ketoacidosis (DKA) is one of the serious complications of type 1 diabetes mellitus and may be aggravated by infection. Diagnosing an infection in a patient with DKA is often complicated becau... This is a retrospective study. The study cohort included 180 children and adolescents with type 1 diabetes mellitus who were admitted to the Pediatric Emergency Department at Shaare Zedek Medical Cent... The incidence of probable bacterial infection in the entire cohort was 13.9%: 15.7% in the DKA group and 7.5% in the non-DKA group ( P = 0.65). The incidence of leukocytosis was significantly higher i... Our findings suggest that leukocytosis in DKA is not a reliable indicator of concomitant bacterial infection. In contrast, CRP levels were not related to the DKA or degree of acidosis and were signifi...

Effect of C-reactive protein on the risk of Heart failure: a mendelian randomization study.

Traditional observational studies have shown positive associations between c-reactive protein (CRP) and heart failure (HF) risk. However, this association has not been fully elucidated. Therefore, Men... We implemented a two-sample Mendelian randomization framework to examine the causality of the association between CRP and HF based on summary statistics by large-scale genome-wide association studies ... The results of our IVW indicated that CRP was strongly associated with HF (OR = 4.18, 95% CI = 3.40-5.13, p < 0.001). The Cochran heterogeneity test showed significant heterogeneity among SNPs of CRP ... Our MR study did identify convincing evidence to support CRP associated with HF risk. Human genetic data suggest that CRP is a causative factor in HF. Hence, CRP assessment may offer additional progno...

Synovial C-Reactive Protein is a Useful Adjunct for Diagnosis of Periprosthetic Joint Infection.

The diagnostic utility of synovial C-reactive protein (CRP) has been debated for a while. Existing studies are limited by small sample sizes and using outdated criteria for periprosthetic joint infect... We reviewed 621 patients who underwent evaluation for PJI prior to revision arthroplasty from 2014 to 2021. Biomarkers, including serum CRP and erythrocyte sedimentation rate, synovial CRP, polymorpho... In total, 194 patients had a PJI; 394 were considered aseptic failures and 33 were inconclusive. Synovial CRP showed an area under the curve (AUC) of 0.951 (95% CI, 0.932-0.970) with 74.2% sensitivity... Synovial CRP demonstrated excellent accuracy when used to determine the presence of PJI. There was a good correlation between serum and synovial CRP levels in revision arthroplasty patients and the co...
