Systemic inflammatory biomarkers and co-morbidities of chronic obstructive pulmonary disease.
    Annals of medicine, 2013, Volume: 45, Issue:3

    Chronic obstructive pulmonary disease (COPD) can no longer be considered as a disease affecting only the lungs. Increasing evidence supports the presence of a systemic inflammatory component which is thought to provide the link between COPD and the co-morbidities commonly associated with this disease. These include cardiovascular disorders, skeletal muscle dysfunction, diabetes, and osteoporosis. The majority of current therapies for COPD have been developed to improve airway obstruction or to target airway inflammation, leaving an unmet medical need with respect to the systemic inflammatory component of COPD and its extra-pulmonary manifestations. This review describes systemic biomarkers in COPD and their relationship with both the local lung and systemic manifestations of the disease. A summary is provided of the most promising biomarkers that have been investigated in COPD and its co-morbidities. Such biomarkers may be used to assess and manage the systemic effects of COPD, and may guide future development of novel therapeutic interventions to provide a more holistic approach to treating this multi-faceted disease.

Polymorphism of the ITGAM gene (rs7193943) and bioelectric impedance analysis as potential predictors of cachexia in chronic heart failure.
    Scientific reports, 2021, 10-11, Volume: 11, Issue:1

    Cardiac cachexia (CC) is an unfavorable metabolic syndrome leading to exacerbation of chronic heart failure (CHF) and a higher risk of death. The main factor contributing to the development of cachexia is the ongoing inflammatory process mediated by genes (e.g. Integrin Subunit Alpha M-ITGAM). The study aimed to assess the relationship between a single nucleotide polymorphism (SNP) -323G > A of the ITGAM and the occurrence of nutritional disorders in patients with CHF. 157 CHF patients underwent clinical and nutritional screening. Body composition was evaluated by bioelectrical impedance analysis (BIA). Patients with cachexia were characterized by significantly lower weight, body mass index (BMI), lower fat mass (FM), albumin, and hemoglobin. Lower values of BIA parameters: capacitance of membrane (Cm), phase angle (PA), and impedance ratio (Z200/Z5) were noted in women. Those patients demonstrated significantly higher values of creatinine, c-reactive protein (CRP), N-terminal prohormone of brain natriuretic peptide (NT-proBNP), and pulmonary artery systolic pressure (PASP). A significantly higher risk of cachexia was reported in patients: aged ≥ 74 years (OR 3.55), with renal failure (OR 3.75), New York Heart Association classification (NYHA) III-IV (OR 2.83), with moderate or severe malnutrition according to the score of subjective global assessment (SGA) (OR 19.01) and AA genotype of ITGAM gene (OR 2.03). Determination of the -323G > A SNP in the ITGAM may prove to be a useful marker (after confirmation in further studies and appropriate validation) in the assessment of the risk of nutritional disorders in patients with CHF.

Fibroblast growth factor 21 in patients with cardiac cachexia: a possible role of chronic inflammation.
    ESC heart failure, 2019, Volume: 6, Issue:5

    Cardiac cachexia is a wasting syndrome characterized by chronic inflammation and high mortality. Fibroblast growth factor 21 (FGF-21) and monocyte chemoattractant protein 1 (MCP-1) are associated with cardiovascular disease and systemic inflammation. We investigated FGF-21 and MCP-1 in relations to cardiac function, inflammation, and wasting in patients with heart failure with reduced ejection fraction (HFrEF) and cardiac cachexia.. Plasma FGF-21 and MCP-1 were measured in a cross-sectional study among the three study groups: 19 patients with HFrEF with cardiac cachexia, 19 patients with HFrEF without cachexia, and 19 patients with ischaemic heart disease and preserved ejection fraction. Patients with HFrEF and cardiac cachexia displayed higher FGF-21 levels median (inter quantile range) 381 (232-577) pg/mL than patients with HFrEF without cachexia 224 (179-309) pg/mL and ischaemic heart disease patients 221 (156-308) pg/mL (P = 0.0496). No difference in MCP-1 levels were found among the groups (P = 0.345). In a multivariable regression analysis, FGF-21 (logarithm 2) was independently associated with interleukin 6 (logarithm 2) (P = 0.015) and lower muscle mass (P = 0.043), while no relation with N-terminal pro-hormone brain natriuretic peptide was observed.. Fibroblast growth factor 21 (FGF-21) levels were elevated in patients with HFrEF and cardiac cachexia, which could be mediated by increased inflammation and muscle wasting rather than impaired cardiac function.

The Relationship of Appetite-Regulating Hormones in the Development of Cardiac Cachexia.
    International heart journal, 2019, Mar-20, Volume: 60, Issue:2

    The physiological control of appetite regulation involves circulating hormones with orexigenic (ghrelin) and anorexigenic (cholecystokinin) properties that induce alterations in energy intake via perceptions of hunger and satiety. We sought to investigate the relationship between appetite-regulating hormones and the cachexia associated with chronic heart failure.We randomized male Sprague-Dawley rats into myocardial infarction (MI) or sham operation (SO) groups. The levels of brain natriuretic peptide (BNP), cholecystokinin (CCK) and ghrelin in the plasma of all rats were detected by enzyme-linked immunosorbent assay (ELISA); the expression of BNP, CCK, and ghrelin in the myocardial tissue of all rats were detected by western blotting, immunohistochemistry, real-time polymerase chain reaction (PCR); myocardial morphology was assessed by microscopy.Plasma BNP and CCK levels in the cardiac cachexia (CC) groups and the heart failure non-cachexia (HF-nc) groups were significantly higher than those in the control groups (P < 0.01), and the expression of BNP and CCK in the myocardial tissue of rats: in CC groups and HF-nc groups were increased compared with the corresponding control groups (P < 0.01). In contrast, Plasma and cardiac expression of ghrelin decreased compared with the sham group (P < 0.01). Furthermore, plasma CCK levels were positively correlated with BNP concentrations (P < 0.001) and significantly negatively correlated with the ejection fraction (P < 0.001) in model animals; plasma ghrelin levels were negatively associated with BNP levels (P = 0.0023) and positively associated with ejection fraction (P = 0.0042).The appetite-regulating hormones (ghrelin and CCK) may present as a potential significant biomarker for cachexia associated with chronic heart failure.

Loss in body weight is an independent prognostic factor for mortality in chronic heart failure: insights from the GISSI-HF and Val-HeFT trials.
    European journal of heart failure, 2015, Volume: 17, Issue:4

    Uncertainties remain on the biological and prognostic significance and therapeutic implications of loss in body weight (W-LOSS) in chronic heart failure (HF) patients. We assessed whether W-LOSS added additional prognostic value to classical clinical risk factors in two separate and large cohorts of patients with chronic HF. The factors associated with W-LOSS were studied.. W-LOSS and estimated plasma volume changes were measured serially in the GISSI-HF (n = 6820) and Val-HeFT trials (n = 4892). In both studies, experiencing at least one episode of ≥5% W-LOSS during the first year of follow-up was considered a sign of wasting. In GISSI-HF, self-reported unintentional W-LOSS ≥2 kg between two consecutive clinical visits within 1 year was also considered a sign of wasting. W-LOSS occurred in 16.4% and 15.7% of the patients enrolled in GISSI-HF and Val-HeFT, respectively (unintentional ≥2 kg W-LOSS occurred in 18.9% in GISSI-HF). In multivariable analyses adjusting for a number of baseline covariates as well as for plasma volume changes, W-LOSS was found to be independently associated with mortality and adverse cardiovascular and non-cardiovascular outcomes, with a significant net reclassification improvement (cfNRI) and an increase in integrated discrimination improvement (IDI). W-LOSS was independently associated with several features representing the severity of HF, including baseline NT-proBNP and high sensitivity C-reactive protein (hsCRP) in Val-HeFT.. W-LOSS was a frequent finding in the GISSI-HF and Val-HeFT trials, associated with multiple patient features, and added additional prognostic information beyond clinical variables of HF severity, including estimated plasma volume changes.

Relationships between right ventricular function, body composition, and prognosis in advanced heart failure.
    Journal of the American College of Cardiology, 2013, Oct-29, Volume: 62, Issue:18

    This study sought to examine the relationships between right ventricular (RV) function, body composition, and prognosis in patients with advanced heart failure (HF).. Previous studies investigating HF-related cachexia have not examined the impact of RV function on body composition. We hypothesized that RV dysfunction is linked to weight loss, abnormal body composition, and worsened prognosis in advanced HF.. Subjects with advanced HF (n = 408) underwent prospective assessment of body composition (skinfold thickness, dual-energy X-ray absorptiometry), comprehensive echocardiography, and blood testing. Subjects were followed up for adverse events (defined as death, transplantation, or circulatory assist device).. Subjects with RV dysfunction (51%) had lower body mass index, lower fat mass index, and were more likely to display cachexia (19%). The extent of RV dysfunction correlated with greater antecedent weight loss and a lower fat/lean body mass ratio. Over a median follow-up of 541 days, there were 150 events (37%). Risk of event was greater in subjects with RV dysfunction (hazard ratio: 3.09 [95% confidence interval (CI): 2.18 to 4.45]) and cachexia (hazard ratio: 2.90 [95% CI: 2.00 to 4.12]) in univariate and multivariate analyses. Increased body mass index was associated with a lower event rate (HR per kg/m(2): 0.92 [95% CI: 0.88 to 0.96]), and this protection was mediated by a higher fat mass (0.91 [95% CI: 0.87 to 0.96]) but not a fat-free mass index (0.97 [95% CI: 0.92 to 1.03]).. RV dysfunction and cardiac cachexia often coexist, have additive adverse impact, and might be mechanistically interrelated. Wasting of fat but not of lean mass was predictive of adverse outcome, suggesting that fat loss is either a surrogate of enhanced catabolism or adipose tissue is cardioprotective in the context of HF.

Prevalence of cachexia in chronic heart failure and characteristics of body composition and metabolic status.
    Endocrine, 2013, Volume: 43, Issue:3

    The prevalence of cardiac cachexia has previously been estimated to 8-42 %. However, novel treatment strategies for chronic heart failure (CHF) have improved and decreased morbidity and mortality. Therefore, we aimed to reassess the prevalence of cachexia in an outpatient CHF clinic and to characterize a CHF population with and without cachexia with respect to body composition and related biomarkers. From 2008 to 2011, we screened 238 optimally treated, non-diabetic CHF patients for cardiac cachexia, defined as unintentional non-oedematous weight loss of >5 % over ≥6 months. CHF patients (LVEF <45 %) with cachexia (n = 19) and without (n = 19) were compared to controls with prior myocardial infarction and left ventricular ejection fraction (LVEF) >45 % (n = 19). The groups were matched for age, sex, and kidney function. Body composition was assessed by dual energy X-ray absorptiometry. The prevalence of cachexia was 10.5 %. Abdominal fat ± SD (%) was reduced in cachectic CHF: 27.4 ± 10.0 versus 37.5 ± 10.6 % (CHF, no cachexia) and 40.6 ± 8.0 % (controls), (P < 0.001). NT-proBNP levels were inversely correlated to abdominal fat in a multivariate linear regression analysis adjusted for known predictors of NT-proBNP (LVEF and NYHA); (β = -0.28; P = 0.018). Myostatin levels were reduced in cachectic CHF compared to controls (P = 0.013). The prevalence of cachexia in stable CHF, treated according to recent guidelines, is lower than previously anticipated. Body alterations in cachexia consist mainly of reduced abdominal fat mass, and its inverse correlation to NT-proBNP suggests involvement of abdominal lipolysis. Our data do not support a role of circulating myostatin as a biomarker for muscle wasting.

The relationship between adiponectin, NT-pro-BNP and left ventricular ejection fraction in non-cachectic patients with systolic heart failure: an observational study.
    Anadolu kardiyoloji dergisi : AKD = the Anatolian journal of cardiology, 2013, Volume: 13, Issue:3

    NT-pro-brain natriuretic peptide (NT-proBNP) has been shown to be an accurate diagnostic marker in patients with heart failure (HF). Adiponectin (Adp) levels are increased in HF but its diagnostic value is still uncertain in these patients. The study was designed to investigate the possible association of these markers in non-cachectic patients with newly diagnosed systolic heart failure.. Fifty-seven systolic HF patients and 20 matched controls were enrolled in an observational cross-sectional study. Physical and echocardiographic examinations were performed and serum Adp, NT-proBNP, tumor necrosis factor-alpha (TNF-α) levels were measured. Study variables were compared between the groups. Correlation analyses were done and the diagnostic validity of the markers was compared with ROC analysis.. Adp and NT-proBNP levels were significantly higher in HF group (20.19±12.9 vs. 7.65±4.6 μg/mL; p<0.001 and 1051.74±606.2 vs. 222.53±65.6 pg/mL; p=0.002; respectively). TNF-α levels were similar between the groups (2.83±1.8 vs. 2.08±1.2 pg/mL; p=0.582). Correlation analysis showed significant association among Adp and NT-proBNP levels, (r=0.448; p<0.001), and left ventricular ejection fraction (LVEF) values (r=-0.466; p<0.001). The Adp and NT-proBNP showed comparable diagnostic performances with mean [95% confidence interval] areas under the curves of 0.857 (0.771-0.944) and 0.888 (0.815-0.960), respectively.. There were significant correlation between Adp levels with NT-proBNP levels and LVEF values but no any association between Adp levels with body mass index values and TNF-α levels in patients with newly diagnosed systolic heart failure. The result may arouse suspicion about the hypothesis, which proposes that Adp levels simply reflects disease severity or cardiac cachexia in patients with HF.. AMAÇ: Kalp yetmezliği (KY) olgularında NT-pro-beyin natriüretik peptid'in (NT-proBNP) tanısal değeri bilinmektedir. Adiponektin (Adp) düzeyleri bu olgularda yükselmektedir, ancak tanısal değeri henüz belirsizdir. Çalışma, yeni tanı almış, kaşektik olmayan sistolik kalp yetmezlikli olgularda söz konusu serum göstergelerinin muhtemel ilişkisinin araştırılması için tasarlanmıştır. YÖNTEMLER: Sistolik KY tanısı konan 57 olgu ile yaş-cinsiyet uyumlu 20 kontrol olgusu gözlemsel kesitsel çalışmaya dahil edildi. Fizik muayene ve ekokardiyografik değerlendirmenin yanı sıra serum Adp, NT-proBNP, tümör nekrozis faktör-alfa (TNF-α) düzeyleri ölçüldü. Çalışma değişkenleri gruplar arasında karşılaştırıldı. Korelasyon analizleri yapıldı ve göstergelerin tanısal geçerliliği ROC analizi ile karşılaştırıldı. BULGULAR: Adp ve NT-proBNP düzeyleri KY grubunda anlamlı şekilde yüksek bulundu (sırasıyla 20.19±12.9'e karşılık 7.65±4.6 μg/mL; p<0.001 ve 1051.74±606.2'e karşılık 222.53±65.6 pg/mL; p=0.002). TNF-α düzeyleri her iki grupta benzerdi (2.83±1.8 vs. 2.08±1.2 pg/mL; p=0.582). Korelasyon analizi Adp ile NT-proBNP düzeyleri (r=0.448; p<0.001) ve Adp ile sol ventriküler ejeksiyon fraksiyon (SVEF) değerleri arasında anlamlı korelasyon olduğunu gösterdi (r=-0.466; p<0.001). ROC analizi ile Adp ve NT-proBNP seviyelerinin karşılaştırılabilir tanısal değere sahip olduğu saptandı: Eğri altında kalan alanlar sırası ile 0.857 (%95 GA; 0.771-0.944 ) ve 0.888 (%95 GA; 0.815-0.960) bulundu. SONUÇ: Yeni tanı almış sistolik kalp yetmezlikli olgularda Adp seviyeleri ile NT-proBNP ve SVEF arasında anlamlı korelasyon mevcut iken; Adp ile beden kitle indeksi ve TNF-α düzeyleri arasında herhangi bir ilişki saptanmamıştır. Bu sonuç Adp seviyelerinin KY olgularında ilerlemiş hastalığın veya kardiyak kaşeksinin bir göstergesi olduğu hipotezi ile çelişmektedir.

Serum adipokine zinc α2-glycoprotein and lipolysis in cachectic and noncachectic heart failure patients: relationship with neurohormonal and inflammatory biomarkers.
    Metabolism: clinical and experimental, 2012, Volume: 61, Issue:1

    Chronic heart failure is often complicated by the development of cachexia with the loss of fat mass. Zinc α2-glycoprotein (ZAG) is a serum adipokine with lipolytic effects in cancer cachexia. We evaluated in patients with advanced heart failure with (CxHF) or without cachexia (nCxHF) the relationship of ZAG with circulating free fatty acid (FFA), as an index of lipolysis, and with other neurohormonal and inflammatory biomarkers. Two groups, nCxHF (n = 46) and CxHF (n = 18), the latter having a documented, involuntary, edema-free loss of body weight of at least 7.5% in the previous 6 months, underwent plasma determination of FFA, ZAG, norepinephrine (NE), tumor necrosis factor-α, and natriuretic peptide levels (atrial natriuretic, B-type natriuretic peptide). The patients were compared with age-matched healthy controls (CTR) (n = 21). Zinc α2-glycoprotein, atrial natriuretic peptide, B-type natriuretic peptide, and tumor necrosis factor-α circulating levels were similarly greater in CxHF and nCxHF than in CTR. Free fatty acid and NE were higher in CxHF than in nCxHF. A positive correlation between FFA and NE was found in both CxHF (r = 0.73, P < .01) and nCxHF (r = 0.48, P < .01) but only in CxHF between ZAG and FFA (r = 0.54, P = .02) and between ZAG and NE (r = 0.70, P < .01). No correlations between natriuretic peptides and ZAG were found. Serum ZAG levels are increased in advanced heart failure patients compared with CTR, without differences between CxHF and nCxHF. Only in CxHF, ZAG levels are directly correlated to circulating levels of FFA and NE, suggesting a close interaction of ZAG with sympathetic-mediated lipolysis.

Elevated myocardial enzymes and natriuretic peptides in anorexia nervosa: prototypic condition for the pathophysiology of cachexia?
    Cardiology, 2011, Volume: 118, Issue:4

    We report on a patient suffering from chronic anorexia nervosa who in the course of treatment showed elevated high-sensitive troponin T, creatine kinase and most markedly N-terminal pro-brain natriuretic peptide (NT-proBNP). Elevated enzymes improved significantly throughout the course of treatment without cardiac specific medication but exceeded the normal range for weeks. Abnormally high myocardial enzymes and NT-proBNP in cachectic anorectic patients might resemble conditions of cardiac cachexia. A review of the available literature is provided. Further research is required to explain the pathophysiological meaning of the abnormal laboratory findings.

The relationship between tumor necrosis factor-α, brain natriuretic peptide and atrial natriuretic peptide in patients with chronic heart failure.
    International journal of cardiology, 2010, May-14, Volume: 141, Issue:1

    Cytokines such as tumor necrosis factor-alpha (TNF) contribute to cardiac dysfunction in chronic heart failure (CHF). Brain natriuretic peptide (BNP) and atrial natriuretic peptide (ANP) are thought to reflect cardiac functional and structural damage.. To study the relationship between BNP, ANP, and TNF, these parameters were measured in fasting venous blood samples of 25 CHF patients (age 66+/-2 years, pVO(2) 17.4+/-2.1 mL/kg/min, NYHA class 2.8+/-0.2, all mean+/-SEM) and 8 healthy controls (age 71+/-2 years). Patients with CHF had higher plasma levels of BNP (p<0.05), ANP (p<0.05), norepinephrine (p<0.01), and echocardiographic left ventricular end-diastolic diameter (LVEDD, p<0.05) compared to controls, whereas TNF and epinephrine were not significantly different. There were significant correlations between natriuretic peptides and markers of inflammation and myocardial dysfunction in CHF patients: BNP vs. TNF (r=0.64, p=0.0006), vs. LVEDD (r=0.59, p=0.0025); ANP vs. TNF (r=0.60, p=0.0016), vs. LVEDD (r=0.65, p=0.0006); TNF vs. LVEDD (r=0.57, p=0.004). After adjustment for NYHA, creatinine clearance, and age TNF correlated with BNP (all p=0.01) and ANP (all p<0.002). The cachectic CHF patients (n=7,>6% weight loss) had the highest BNP (p<0.001 vs. controls, p<0.05 vs. non-cachectic CHF) and ANP levels (p=0.01 vs. controls). Concentrations of uric acid, epinephrine, and norepinephrine also correlated with ANP and BNP.. In CHF, TNF is closely related to BNP and ANP (independently of CHF severity and ventricular dysfunction), particularly in patients with cardiac cachexia. TNF may causally contribute to intrinsic cardiac dysfunction thereby stimulating BNP and ANP secretion.

Natriuretic peptides and other biomarkers in chronic heart failure: from BNP, NT-proBNP, and MR-proANP to routine biochemical markers.
    International journal of cardiology, 2009, Mar-06, Volume: 132, Issue:3

    Cardiac biomarkers play an important role in heart failure. The family of natriuretic peptides, especially B-type natriuretic peptide, was identified as a valued diagnostic and prognostic tool. Not unexpectedly, the natriuretic peptides fail to fulfill all the criteria of an ideal biochemical marker. The quest for a single marker or a combination is therefore still on and several established, widely available biomarkers might have been overlooked in the field of heart failure. This review puts forward some of those biomarkers, and we speculate on the possible roles of combining two or more biomarkers. In that sense, any blood parameter including hemoglobin, cholesterol, uric acid, and recently identified proteins might function as a biomarker. Additionally, several biomarkers are discussed and we try to anticipate their diagnostic and prognostic value along with the natriuretic peptides and established biomarkers. Finally, we speculate about the potential of sharing the biomarkers over a variety of chronic diseases with similar pathophysiology.

Increase in serum adiponectin concentration in patients with heart failure and cachexia: relationship with leptin, other cytokines, and B-type natriuretic peptide.
    European heart journal, 2007, Volume: 28, Issue:7

    Adiponectin is a fat-derived hormone involved in the regulation of metabolism. Adiponectin concentration is inversely related to body weight and, in animals, causes weight loss. We, therefore, measured adiponectin concentration in patients with heart failure (HF) and cachexia.. Serum adiponectin concentrations were measured in three groups of patients with coronary artery disease (CAD): (i) HF, reduced left ventricular systolic function, and cachexia (n = 10); (ii) HF, reduced systolic function but no cachexia (n = 20); (iii) HF-controls-patients with CAD, no HF, and preserved systolic function (n = 10); and in a healthy control group (n = 7). Patients with HF and cachexia had higher concentrations of adiponectin [23.8 (10.2-37.2) microg/mL] than all other groups: HF-no cachexia 8.1 (0.5-16.6) microg/mL; CAD-controls 7.1 (0.4-13.5) microg/mL; and healthy controls 8.7 (2.5-16.8) microg/mL) (P < 0.05 for each comparison). Adiponectin correlated negatively with body mass index, percentage of body fat, waist circumference and insulin resistance, and positively with B-type natriuretic peptide (BNP) and tumour necrosis factor-alpha.. Cachexia in HF is associated with an increase in adiponectin concentration. This may represent preservation of the physiological response to change in body fat but might also suggest that adiponectin plays a role in the pathogenesis of cachexia. The correlation between BNP and adiponectin also raises the possibility that the former might increase the secretion of the latter.
