Resistin serum levels and its association with clinical profile and carotid intima-media thickness in psoriasis: a cross-sectional study

BackgroundPsoriasis is a protean disease associated with several comorbidities that may have increased levels of adiponectin such as resistin. This may affect the patients atherosclerotic risk. ObjectiveTo study resistin levels in a sample of Brazilian patients with psoriasis and its association with clinical profile, comorbidities, and carotid Intima-Media Thickness (cIMT). MethodsThis is a cross-sectional study of 119 individuals: 34 healthy controls and 85 patients with psoriasis, 42 of which with skin involvement only and 43 with psoriatic arthritis. Clinical and epidemiological data, measurement of PASI (Psoriasis Area Severity Index) and DAPSA (Disease Activity in Psoriatic Arthritis), lipid profile, cIMT by ultrasound were collected from medical records. Resistin serum levels were measured by ELISA. ResultsPatients with psoriasis had higher resistin levels (p=0.009) and worse cIMT (p=0.0002) than controls. In the psoriasis sample, no associations of resistin levels with epidemiological, clinical findings, and activity indexes were found. Resistin serum levels were associated with the presence of diabetes (p=0.008) and metabolic syndrome (p=0.01) and correlated with total cholesterol (r=0.26) and triglycerides (r=0.33) but not with cIMT. Study limitationsThis work is limited by its transversal design and by the limited number of patients included. ConclusionResistin serum levels are elevated in psoriasis patients. In this sample, clinical, epidemiological, and activity indexes were not linked to resistin serum levels, but atherosclerotic risk factors were.

Association between Resistin and High Sensitive Troponin I in St Elevation Myocardial Infarction and Systolic Heart Failure

Background: Nearly half of all patients with acute myocardial infarction (AMI) have left ventri­cular systolic dysfunction and one-third have symptoms of heart failure (HF). In patients with AMI the resistin level correlated inversely with left ventricular ejection fraction (LVEF). Increased levels of high sensitive (hs) troponin I are associated with poorer prog­nosis. This study aimed to deter­mine the association between levels of resistin and hs troponin I in ST elevation myocardial infarc­tion (STEMI) patients with systolic HF. Subjects and Method: This was a cross-sectional study was conducted at Dr. Moewardi Gene­ral Hospital, Surakarta, from April 1 to May 31, 2018. A sample of 32 patients who admitted which diagnosed with STEMI was selected for this study. They were divided into two group according to result of LVEF mea­sure­ment, LVEF < 40% and LVEF ≥ 40%. Blood examination and transthoracic echo-car­diography were performed to all patients. Cor­re­lation test using partial and multiple cor­relation test. To different 2 mean using Mann Whitney test. Results: Mean of patient age was 59.5 years old. Resistin decreased LVEF (r= -0.41; p= 0.009), and it was statistically significant. Hs troponin I decreased LVEF (r= -0.25; p= 0.081), but it was marginally significant. Resis-tin level and hs troponin I increased LVEF (r= 0.47; p= 0.025), and it statistically significant. Conclusion: There was an association between resistin and hs troponin I level together in STEMI patients with systolic HF. There was an association of resistin levels in STEM I patients with systolic HF. There was no association of hs troponin I levels in STEMI patients with systolic HF.

Association of resistin level with acanthosis nigricans in obese adolescents

Background Childhood obesity is associated with increased risk of cardiovascular diseases and metabolic syndrome, such as insulin resistance. Clinically, insulin resistance may be manifested as acanthosis nigricans. Resistin has a biological activity that is important in glucose and lipid metabolisms and closely related to the incidence of insulin resistance.Objective To find out the association of resistin level with scale of acanthosis nigricans in adolescents obesity.Methods A cross-sectional study was conducted on 53 obese adolescents with acanthosis nigricans in senior high schools in Padang, West Sumatera. Degree of acanthosis nigricans was assessed using scale of Burke and then plasma resistin level was performed with ELISA. Data were analyzed using ANOVA and post-hoc test.Result The mean of resistin level in obese adolescents was 14.21 (SD 7.43) ng/dL. High resistin level was found in scale of acanthosis nigricans 2,3 and 4 (P=0.0001). Obese adolescents with severe degree of acanthosis nigricans has higher resistin level compared to milder acanthosis nigricans.Conclusion In obese adolescents, the higher degree of acanthosis nigricans, the higher level of plasma resistin.

Associations of Resistin Levels with Resistin Gene Polymorphism and Metabolic Syndrome in Thais.

SummaryBackgroundMetabolic syndrome (MS) is a clinical constellation comprising risk factors associated with developing cardiovascular disease and type 2 diabetes. Resistin has been suggested as a linkage between obesity, inflammation and type 2 diabetes. This study aimed to investigate resistin concentrations and hematological-biochemical parameters in MS subjects and controls, and to determine whether two resistin gene (RETN) polymorphisms (−420C>G & +299G>A) are linked to resistin levels and MS among Thais.MethodsThis case-control study was performed with 322 Thai volunteers: 160 MS subjects and 162 controls. Anthropometric parameters and hematological-biochemical variables were determined. The RETN −420C>G (rs1862513) and +299G>A (rs3745367) polymorphisms were genotyped by PCR-RFLP technique.ResultsThe resistin levels of the MS group were significantly higher than those of the control group. Resistin levels were positively correlated with anthropometric parameters and WBC count in the MS group. According to RETN −420C>G polymorphism, MS subjects with the G allele (CG/GG) (3.9 μg/L) had significantly higher resistin concentrations than in subjects with the CC genotype (2.4 μg/L); with regard to RETN +299G>A polymorphism, carriers with the A allele (GA/AA) (3.8 μg/L) had significantly higher resistin levels than subjects with the GG genotype (2.7 μg/L), after adjusting for potential covariates. However, the RETN −420C>G and +299G>A polymorphisms were not found to be associated with MS, hematological-biochemical parameters and anthropometric variables.ConclusionsThese findings suggest resistin levels are linked with MS and the RETN −420C>G and +299G>A polymorphisms have impacted the circulating resistin concentrations. However, these two RETN polymorphisms probably do not influence susceptibility to MS among Thais.

Circulating resistin is increased with decreasing renal function in a general Japanese population: the Hisayama Study

The purpose of this study is to investigate the relationship between serum resistin levels and chronic kidney disease (CKD). A total of 3192 community-dwelling subjects (1377 men, 1815 women), aged ≥40 years and without renal failure, were divided into four groups according to quartiles of serum resistin concentrations: ≤7.1, 7.2-9.9, 10.0-14.7 and ≥14.8 ng/mL. The associations of resistin levels with renal function status were examined cross-sectionally. The estimated glomerular filtration rate (eGFR) was calculated using the equation from the Modification of Diet in Renal Disease Study, and CKD was defined as an eGFR of <60 mL/min/1.73 m(2). The age- and sex-adjusted mean values of eGFR decreased significantly with elevating quartiles of resistin (P for trend <0.001). The age- and sex-adjusted odds ratios (ORs) for the presence of CKD increased progressively with higher quartiles of resistin. This trend remained robust even after controlling for age, sex, body mass index, diabetes, homeostasis model assessment of insulin resistance (HOMA-IR), high-sensitivity C-reactive protein (hs-CRP), triglycerides, high-density lipoprotein and total cholesterol, hypertension, current smoking, current drinking, and regular exercise [second quartile: OR 1.44, 95% confidence interval (CI) 1.05-1.99; third quartile: OR 2.15, 95% CI 1.58-2.92; fourth quartile: OR 2.32, 95% CI 1.71-3.16; P for trend <0.001]. In stratified analyses, high resistin level (≥7.2 ng/mL) was a significant relevant factor in CKD, independent of HOMA-IR or hs-CRP level. Conclusion. Our findings suggest that elevated resistin level is significantly associated with the likelihood of CKD in the general Japanese population.

Serum adipokine levels in chronic liver diseases: Association of resistin levels with fibrosis severity

Objective. Leptin and adiponectin have been implicated in the pathogenesis and progression of non-alcoholic steatohepatitis (NASH) and chronic hepatitis C (CHC), but little is known about the role of resistin in chronic liver diseases. The objective of this study was to investigate serum levels of the above three adipokines in relation to the etiology of liver disease and to determine their associations with histological severity. Material and methods. We prospectively evaluated 146 patients (HBeAg-negative chronic hepatitis B (CHB): 52, CHC: 70, NASH: 24) who consecutively underwent liver biopsy. Detailed epidemiological, anthropometric and laboratory data were recorded. Histological lesions were evaluated blindly according to the Ishak and the Brunt classifications for CHB/CHC and NASH, respectively. Results. Serum adipokine levels were similar between CHB and CHC patients, while CHB/CHC patients had significantly lower leptin levels compared with NASH patients (8.3±7.3 versus 17.6±16.6 ng/ml, p=0.012) and higher adiponectin (10.2±5.1 versus 7.5±4 µg/ml, p=0.018) and resistin levels (7.1±2.5 versus 5.7±2.8 ng/ml, p=0.016). In CHB/CHC, there was no significant association between steatosis or necroinflammation and levels of adipokines, while the presence of moderate/severe fibrosis (stages 4–6) was associated with higher leptin and adiponectin levels in male but not in female patients and with lower resistin levels irrespective of gender or other factors (adjusted odds ratio=0.788, p=0.035). Conclusions. Serum adipokine levels depend on the etiology of liver disease differing between chronic viral hepatitis and NASH, but not between CHB and CHC. In CHB/CHC, resistin levels are independently associated with fibrosis severity, whereas in the association of leptin and adiponectin levels with fibrosis, it seems to be a gender effect.

Relationships between human serum resistin, inflammatory markers and insulin resistance

Data on the association of resistin levels with markers of insulin resistance are highly contrasting in humans and very few studies about its role in inflammation are available. This study investigates associations between serum resistin levels and markers of insulin resistance, inflammation (C-reactive protein (CRP)) and of oxidative stress (nytrotirosine (NT)). A randomly collected sample of 300 men from a population-based cohort was analysed, separated into two groups according to body mass index (BMI) and waist values. Correlations between resistin and BMI, waist, triglyceride, uric acid, fasting glucose, insulin and Homeostasis Model Assessment (HOMA) values were significant in subjects with normal BMI, but not in overweight/obese subjects. In a multiple regression model, after multiple adjustments and exclusion of diabetic patients, only fasting glucose remained significantly associated with resistin levels. Otherwise, resistin is associated to CRP levels in all individuals, after multiple adjustments and exclusion of diabetic patients (in normal BMI beta=0.82; 95% CI 0.21, 1.42; in overweight/obese beta=0.43; 95% CI 0.10, 0.76). In the same model, resistin values are negatively related to NT levels in normal weight individuals (beta=-1.61; 95% CI -0.77-2.45). Serum resistin is weakly associated with metabolic abnormalities in subjects with normal BMI, while in overweight/obese patients this correlation is not significant, perhaps due to the higher fat content in these subjects. Serum resistin is directly correlated with CRP and inversely to NT. An intriguing hypothesis, which needs to be tested, is that resistin is secreted in response to a chronic low-grade inflammation, and has antioxidant properties.
