INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18062985. [PMID: 33799436 PMCID: PMC7998110 DOI: 10.3390/ijerph18062985] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 03/08/2021] [Accepted: 03/10/2021] [Indexed: 01/02/2023]
Abstract
BACKGROUND The aim of this study was to determine whether a causative relationship exists between the development of liver damage and increased high-sensitivity C-reactive protein (HsCRP) levels by long-term follow-up in Japanese workers. METHODS The target participants comprised 7830 male workers in a Japanese steel company. The prospective cohort study was performed over a 6-year period, and annual health screening information was analyzed by pooled logistic regression. The endpoint, regarded as the development of liver damage, was defined as aspartate aminotransferase (AST) ≥ 40 IU/L. RESULTS A significant relationship between the development of liver damage and increased HsCRP levels was observed after adjusting for confounding factors such as various physiological and blood chemistry parameters and lifestyle factors. The odds ratio of a 1.5-fold increase in HsCRP was 1.07 (95% confidence interval: 1.03-1.10, p < 0.001). CONCLUSIONS The results suggested that an increase of HsCRP is associated with the development of liver damage.

High-Sensitivity C-Reactive Protein Leads to Increased Incident Metabolic Syndrome in Women but Not in Men: A Five-Year Follow-Up Study in a Chinese Population. Diabetes Metab Syndr Obes 2020; 13:581-590. [PMID: 32184637 PMCID: PMC7055523 DOI: 10.2147/dmso.s241774] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Accepted: 02/15/2020] [Indexed: 12/13/2022] Open
Abstract
PURPOSE Metabolic syndrome (MetS), characterized by a constellation of insulin resistance, central obesity, hypertension, and hyperlipidemia, is a global health threat. High-sensitivity C-reactive protein (hs-CRP) has been shown to be associated with type 2 diabetes and cardiovascular disease; however, its association with incident MetS is less known. Therefore, the aim of this study was to examine the prospective association between hs-CRP and MetS among a Chinese population in a 5-year follow-up study. PATIENTS AND METHODS The levels of hs-CRP were measured using serum samples collected at baseline recruitment in 2012 from 886 participants without MetS. Follow-up interviews were conducted in 2018, and MetS was diagnosed by 2017 criteria from the Chinese Diabetes Society. Multivariate logistic regression models were used to assess the overall and sex-specific associations between hs-CRP and incident MetS. The odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were computed with adjustment for demographic, socioeconomic, clinical, and lifestyle factors. RESULTS After a mean follow-up duration of 5.40 ± 0.56 years, 116 (13.3%) participants developed MetS. In the total study population, increased hs-CRP levels were associated with a higher risk of MetS (OR comparing extreme quartiles of hs-CRP: 4.06 [95% CI: 1.91-8.65]) in the fully-adjusted model. When stratified by sex, the positive association was only observed in women (OR: 4.82 [1.89-12.3]) but not in men (OR: 3.15 [0.82-12.1]; P-interaction = 0.039). CONCLUSION In this study of a Chinese population, a positive association between hs-CRP and incident MetS was found only in women and not in men. Sex-specific prediction and intervention of MetS using hs-CRP as a target should be further evaluated.

Associations of serum CRP levels with demographics, health behaviors, and risk of cancer among the Mexican American Mano A Mano Cohort. Cancer Epidemiol 2019; 60:1-7. [PMID: 30878797 DOI: 10.1016/j.canep.2019.03.001] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Revised: 03/01/2019] [Accepted: 03/01/2019] [Indexed: 02/08/2023]
Abstract
C-Reactive protein (CRP) is a well-known inflammatory marker, and elevated CRP levels has been reported to be associated with the risk of various cancers. To date, no study has investigated the association between elevated CRP and incidents of cancer among Mexican Americans. In the current prospective cohort study, we measured pre-diagnostic CRP levels in serum samples and evaluated their relationships with demographic characteristics and health behaviors associated with cancer risk among 2753 Mexican Americans selected from the Mano-A-Mano Mexican American Cohort Study. At baseline, median levels of serum CRP significantly differed by demographics (sex, age category, marital status, and education levels) and health behaviors (cigarette smoking status, alcohol drinking status, BMI category, and physical activity levels). In the multivariable analysis, the study participants who were women, older, never drinking alcohol, overweight or obese, and physically inactive had increased likelihood of having high CRP levels (≥ median levels among all study participants) compared to their counterparts. A total of 177 cancer cases were identified during the follow-up with a median follow-up time of 127 months. In the quartile analysis, study participants in the 4th quartile with highest CRP levels had significantly 1.88 fold increased risk of cancer (hazard ratio (HR) = 1.88, 95%CI: 1.12, 3.13) compared to those in the 1st quartile with lowest CRP levels. The association was further confirmed in analyses using clinical CRP levels. In summary, our findings suggested that serum CRP levels have potential to serve as a predictive marker of cancer risk in Mexican Americans.

Abstract
Diabetic kidney disease is a common complication of type 1 and type 2 diabetes and is the primary cause of end-stage renal disease in developed countries. Early detection of diabetic kidney disease will facilitate early intervention aimed at reducing the rate of progression to end-stage renal disease. Diabetic kidney disease has been traditionally classified based on the presence of albuminuria. More recently estimated glomerular filtration rate has also been incorporated into the staging of diabetic kidney disease. While albuminuric diabetic kidney disease is well described, the phenotype of non-albuminuric diabetic kidney disease is now widely accepted. An association between markers of inflammation and diabetic kidney disease has previously been demonstrated. Effector molecules of the innate immune system including C-reactive protein, interleukin-6, and tumor necrosis factor-α are increased in patients with diabetic kidney disease. Furthermore, renal infiltration of neutrophils, macrophages, and lymphocytes are observed in renal biopsies of patients with diabetic kidney disease. Similarly high serum neutrophil and low serum lymphocyte counts have been shown to be associated with diabetic kidney disease. The neutrophil-lymphocyte ratio is considered a robust measure of systemic inflammation and is associated with the presence of inflammatory conditions including the metabolic syndrome and insulin resistance. Cross-sectional studies have demonstrated a link between high levels of the above inflammatory biomarkers and diabetic kidney disease. Further longitudinal studies will be required to determine if these readily available inflammatory biomarkers can accurately predict the presence and prognosis of diabetic kidney disease, above and beyond albuminuria, and estimated glomerular filtration rate.

Atherosclerosis associated with dynamic inflammation changes after multifactorial intervention in short-duration type 2 diabetes: A randomized, controlled, 10-year follow-up trial. J Diabetes Complications 2017; 31:1286-1292. [PMID: 28610945 DOI: 10.1016/j.jdiacomp.2017.05.008] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2017] [Revised: 05/07/2017] [Accepted: 05/17/2017] [Indexed: 12/31/2022]
Abstract
PURPOSE To analyze the impact of dynamic changes in inflammation on atherosclerosis in short-duration type 2 diabetes after multifactorial intervention. METHODS In this randomized controlled study, a total of 150 type 2 diabetes patients who had a mean age of 49.8±7.3years, 51% male, with disease duration <1year and without evidence of atherosclerosis were randomized into an intensive intervention group (IG), in which patients received multiple risk factors intervention by the special project team and tried to reach the pre-determined intervention goals, and a conventional group (CG), in which patients received standard diabetes care by the clinic doctor. All patients recieved intervention study for 7 years, then underwent a 3-year observational follow-up study. The primary endpoints were occurrence of subclinical atherosclerosis, defined as the intima-media thickness of the common carotid artery (CC-IMT)≥1.0mm or formation of atherosclerosis plaques, and the occurrence of cardiovascular events. RESULTS 68 patients in IG and 65 patients in CG completed the 10-year study. The cumulative incidence of subclinical atherosclerosis was 30.7% vs 57.3% (IG vs CG, HR 0.36, 95% CI 0.22-0.60, P<0.0001) and that of cardiovascular events was 12.0% vs 22.7% (IG vs CG, HR 0.46, 95% CI 0.21-0.98, P=0.0516). High sensitivity C-reactive protein (hs-CRP) reduction from baseline to the 10-year follow-up was -1.54mg/L (IG) and -0.67mg/L (CG) with difference (IG minus CG) of -0.87mg/L(95% CI -0.72 to -1.02, P=0.008) and the natural logarithm of serum amyloid A (SAA) reduction was -4.04 (IG) and -1.44 (CG) with difference (IG minus CG) of -2.60 (95% CI -2.30 to -2.90, P=0.002). The decrease in general score of inflammatory markers (combination of hs-CRP and SAA) was independently associated with subclinical atherosclerosis (OR=0.65, P=0.045) and cardiovascular events (OR=0.60, P=0.042). CONCLUSIONS Dynamic changes in inflammation act as an important factor that affects the occurrence of atherosclerosis in type 2 diabetes patients. Multifactorial intensive intervention can reduce systemic low-grade inflammation and delay the occurrence of atherosclerosis in short-duration type 2 diabetes.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) has reported to be a major public health crisis in China. OBJECTIVE We examined the incidence of new T2DM over 4 years for association of clinical factors and lipids with development of T2DM in a community-based population. METHODS We included 923 Chinese subjects who participated in community-organized health checkout in both 2009 and 2013. Health history was collected; physical examination was performed; biochemistry, lipids, and glucose were measured. Of 923, 819 were confirmed without T2DM in 2009 and included in the analysis. Unadjusted and adjusted logistic regression models were used to estimate the effects of clinical factors and biomarkers on the risk of new T2DM. RESULTS Of 819 subjects without T2DM in 2009, 65 were identified as T2DM in 2013, 8% over 4 years. These 65 subjects, compared with those 754 without new T2DM, were older, more likely to be male and smokers. They had higher body mass index (BMI), fasting glucose, blood pressure and triglycerides, and lower levels of high-density lipoprotein-cholesterol and apolipoprotein A1 (ApoA1). Multivariate logistic regression identified larger BMI (odds ratio [OR] = 1.7; 95% confidence interval [CI], 1.22-2.39, P = .002), higher fasting glucose levels (OR = 4.2, 95% CI, 2.90-6.19, P < .001), and low levels of ApoA1 (OR = 0.51, 95% CI 0.33-0.76, P = .002) were independently associated with new T2DM. Furthermore, receiver operating characteristics curves for multivariate models for new T2DM showed that area under the curve improved from 0.87 to 0.89 when adding ApoA1 to the Framingham Diabetes Risk Scoring Model and from 0.85 to 0.89 when adding ApoA1 to a 4-variable (age, BMI, glucose, and triglycerides) Chinese model. CONCLUSIONS There is a high incidence of new T2DM at 8% over 4 years among Chinese. Larger BMI, higher glucose levels, and lower levels of ApoA1 are significantly and independently associated with new T2DM. Lower ApoA1 improves the risk prediction of new type 2 diabetes when it was added to the existing risk models.

Abstract
A smartphone-based colorimetric reader (SBCR), comprising a Samsung Galaxy SIII mini, a gadget (iPAD mini, iPAD4, or iPhone 5s) and a custom-made dark hood and base holder assembly, is used for human C-reactive protein (CRP) immunoassay. A 96-well microtiter plate (MTP) is positioned on the gadget's screensaver to provide white light-based bottom illumination only in the specific regions corresponding to the well's bottom. The images captured by the smartphone's back camera are analyzed by a novel image processing algorithm. Based on one-step kinetics-based human C-reactive protein immunoassay (IA), SBCR is evaluated and compared with a commercial MTP reader (MTPR). For analysis of CRP spiked in diluted human whole blood and plasma as well as CRP in clinical plasma samples, SBCR exhibits the same precision, dynamic range, detection limit, and sensitivity as MTPR for the developed IA (DIA). Considering its compactness, low cost, advanced features and a remarkable computing power, SBCR is an ideal point-of-care (POC) colorimetric detection device for the next-generation of cost-effective POC testing (POCT).

Abstract
The peroxisome proliferator-activated receptors (PPARs)-α, -β/δ, and -γ are the ligand-activated transcription factors that function as the master regulators of glucose, fatty acid and lipoprotein metabolism, inflammation, and atherosclerosis. Our aim was to test the association between ten single nucleotide polymorphisms of PPARs and CRP level, as well as their interaction with overweight/obesity. A sample population of 643 subjects was recruited from the prevention of MetS and multi-metabolic disorders in Jiangsu Province of China Study. The selected SNPs in PPAR α (rs135539, rs4253778, rs1800206), PPAR β/δ (rs2016520 and rs9794), and PPAR γ (rs10865710, rs1805192, rs709158, rs3856806, and rs4684847) were genotyped. After adjustment for smoking, alcohol consumption, SBP, DBP, TG, and HDL-C, rs1800206, rs709158, rs1805192, and rs4684847 polymorphisms were significantly associated with CRP level in normal weight subjects (P < 0.05). In the overweight/obese subjects, rs1800206 was also significant associated with CRP level (P<0.01). In addition, the rs709158, rs1805192, and rs4684847 polymorphisms were shown interactions with overweight/obesity to influence CRP level (P<0.05). PPARs polymorphisms are independently associated with CRP levels in Chinese Han population. Further, PPARs polymorphisms interact with overweight/obesity to set CRP levels.
