Additional Benefits of Serum Oncostatin M Levels Compared to Cardiac Troponin in Non-ST Elevation Myocardial Infarction.

Background: The use of high-sensitivity troponin levels increases the sensitivity of the diagnosis of non-ST elevation myocardial infarction (NSTEMI). However, the inclusion of other factors in the differential diagnosis, apart from atherothrombosis causing myocardial injury, decreases the specificity of high-sensitivity troponin. In this study, we compared the efficacy of high-sensitivity troponin with serum oncostatin M in NSTEMI cases with elevated urea and creatinine. Methods: This study was performed with a prospective cross-sectional sample. Ninety participants with coronary angiography performed due to a preliminary diagnosis of NSTEMI were included. High-sensitivity troponin I, creatine kinase-MB, lactate dehydrogenase, serum transaminase and oncostatin M levels were quantitatively measured for the first 4-8 hours from the onset of symptoms. All participants had coronary angiography performed within the first 12 hours after attending the emergency service. Based on coronary angiography data, patients with significant coronary stenosis or occlusion detected during coronary angiography were defined as group A, and patients with no occlusion in the coronary artery and who did not require an additional interventional procedure were defined as group B. The SYNTAX 2 score was used to determine the severity of coronary artery disease. Results: Patients in both groups A and B had similar age, sex distribution and comorbidities. Group A had higher serum urea, creatinine, oncostatin M and high-sensitivity troponin I values than group B. With 585 pg/ml as the cut-off value, serum oncostatin M had a sensitivity of 88.6% and specificity of 85% for the diagnosis of NSTEMI. Logistic regression multivariate analysis showed that serum oncostatin M and high-sensitivity troponin I values had diagnostic efficacy for NSTEMI. Serum oncostatin M was found to be more effective than high-sensitivity troponin I in patients with elevated urea and creatinine. Conclusions: Serum oncostatin M had similar sensitivity and specificity for NSTEMI diagnosis as high-sensitivity troponin I. Serum OSM can especially be considered as a complementary diagnostic biomarker for NSTEMI in patients with renal dysfunction.

O Nível de Endocan Sérico pode ser Usado como Biomarcador para Prever Aterosclerose Subclínica em Pacientes Pré-Diabéticos? / Can the Serum Endocan Level Be Used as a Biomarker to Predict Subclinical Atherosclerosis in Patients with Prediabetes?

Resumo Fundamento Pacientes pré-diabéticos têm um risco aumentado de doença cardiovascular aterosclerótica, e, portanto, a detecção precoce é importante. Objetivo Nosso estudo teve o objetivo de revelar a usabilidade dos níveis de endocan sérico como biomarcador no diagnóstico de aterosclerose subclínica em pacientes pré-diabéticos, com base em medições de EIMC. Métodos Os participantes foram classificados de acordo com a presença (n=42) ou ausência (n=42) de pré-diabetes.

O nível de significância para a análise estatística foi 0,05. Resultados Apesar de se ter determinado que os níveis de endocan sérico são mais baixos em pacientes pré-diabéticos em comparação com o grupo de controle (p=0,042), determinou-se que os valores de EIMC são mais altos (p=0,046). A avaliação do endocan sérico por análise regressiva multivariada detectou que seu nível estava associado à EIMC, independentemente de outros parâmetros (p=0,007). Encontramos uma correlação negativa entre insulina plasmática em jejum e níveis de endocan (r=-0,320, p=0,001). Conclusões Este estudo demonstrou que a espessura íntima-média de carótida é mais alta e o nível de endocan sérico é mais baixo em pacientes pré-diabéticos. Os níveis de endocan sérico diminuídos em pacientes pré-diabéticos podem ser um fator que contribui para os mecanismos de formação de aterosclerose.

Abstract Background Patients with prediabetes have an increased risk of atherosclerotic cardiovascular disease; therefore, early detection is important. Objective The present study aimed to reveal the usability of serum endocan levels as a biomarker in the diagnosis of subclinical atherosclerosis in patients with prediabetes, based on CIMT measurements. Methods Participants were classified according to the presence (n=42) or absence (n=42) of prediabetes. Serum endocan, fasting blood sugar, fasting insulin, and glycated hemoglobin (HbA1c) values of patients were examined, and CIMT was measured. The level of significance for statistical analysis was 0.05. Results While serum endocan levels were found to be lower in patients with prediabetes, when compared to the control group (p=0.042), CIMT values were found to be higher (p=0.046). When evaluated by multivariate regression analysis, the serum endocan level was found to be associated with CIMT, regardless of other parameters (p=0.007). A negative correlation was found between plasma fasting insulin and endocan levels (r=-0.320, p=0.001). Conclusions Carotid intima media thickness was found to be high and the serum endocan level was low in patients with prediabetes. Decreased serum endocan levels in patients with prediabetes may be a contributing factor to atherosclerosis formation mechanisms.

Original Article: Clinical Research.

AIM: In this study, we aimed to investigate the possible role of endotrophin, a profibrotic byproduct of collagen VI, in the complex process of fibrosis development in the disease group with pulmonary fibrosis among interstitial lung diseases. MATERIAL AND METHOD: When the patients' participation in the study were completed, smoking or alcohol drinking conditions, and family history were recorded. Their weights and heights were recorded and body mass index (BMI) was calculated. In every patient, Spirometry with bronchodilator testing, determination of single-breath DLCO, and plethysmographic measurement of thoracic gas volume and airway resistance were performed. Blood samples were obtained for the inflammation markers such as sedimentation rate, C-reactive protein (CRP), complete blood count, liver and renal function tests, and lactate dehydrogenase levels. Serum endotrophin levels were measured in all patients. RESULTS: Thirty-five patients with interstitial lung disease who were having pulmonary fibrosis, 35 patients with interstitial lung disease without pulmonary fibrosis, and 20 control patients without any signs or symptoms of interstitial lung disease were included in the study. Age distribution was similar between groups. The fibrotic ILD group was more commonly smoker or ex-smoker compared with the non-fibrotic ILD patients or control cases. Fibrotic ILD patients were leaner, having significantly decreased total lung capacity, diffusion capacity, and higher LDH levels. In the comparison of the 3 study groups regarding the endotrophin levels, there was a significant difference between groups. The fibrotic and non-fibrotic patient groups were compared for the Endotrophin levels and the difference was also significant. However, there was not any significant difference regarding the endotrophin levels between control cases and non-fibrotic ILD patients. Smoked cigarette pocket x year showed a significant positive correlation and DLCO % and KCO % showed a significant negative correlation with the endotrophin levels. CONCLUSION: Serum endotrophin levels significantly increase in fibrotic ILD patients compared with the non-fibrotic ILD patients and control cases. Endotrophin may be suggested as a diagnostic marker in fibrotic interstitial lung diseases.

The association of laminin levels with insulin resistance and non-alcoholic hepatosteatosis.

BACKGROUND: Laminin, one of the largest glycoproteins of the basement membrane, is an important component of the extracellular matrix. Functions of the basement membrane include regulation of cell signaling behaviors and structural support. Laminin plays a critical role in the regulation of insulin action in muscle, liver, and adipose tissue. The study mainly investigates an association between the change in serum laminin levels and insulin resistance and non-alcoholic hepatosteatosis. METHODS: This prospective study included a total of 90 participants; 60 patients diagnosed with Grade 2-3 non-alcoholic hepatosteatosis and 30 age- and sex-matched healthy controls between December 2019 and December 2020. Routine laboratory tests including glucose, insulin, homeostatic model of assessment-insulin resistance (HOMA-IR), alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and C-reactive protein and laminin levels were measured in the serum of the patient and control groups. Enzyme-linked immunosorbent assay was used for the measurement of laminin levels. RESULTS: The median serum laminin levels were lower in patients with hepatic steatosis, compared to the control group (72 ng/L vs. 82 ng/L, respectively; p = 0.003). In the patients with insulin resistance, median laminin levels were lower, regardless of the presence of non-alcoholic hepatosteatosis (67 ng/L vs. 85 ng/L, respectively; p = 0.007). There was a weak, negative correlation between the laminin levels and HOMA-IR. CONCLUSIONS: Our study results suggest that, although there is no exact link between laminin and non-alcoholic hepatosteatosis, serum laminin levels are lower in patients with insulin resistance by regulating the insulin effect through integrins.

Correlation of glycemic regulation and endotrophin in patients with type 2 Diabetes; pilot study.

BACKGROUND: Endotrophin is one of the extracellular matrix proteins secreted by adipose tissue. In this study, we aimed to investigate the effects of changes in blood glucose levels on serum endotrophin levels secreted by adipose tissue and thus on diabetes. METHODS: In this prospective pilot study included 78 patients with type 2 diabete (T2D) with hemoglobin A1c level > 9 %. Lifestyle changes were recommended and appropriate medical treatment was initiated to all patients in order to reach the target HbA1c level. Data of anthropometric measurements, urinary albumin creatinine ratio (UACR), serum lipid parameters and endotrophin were collected in patients; all examinations were repeated after 3 months. Analysis was performed using Paired-Samles T test and Spearman tests. RESULTS: Of patients, 23 were female (54.8 %) and 19 were male (45.2 %). Mean age was 55.2 years, with mean diabetes age of 8.14 ± 5.35 years. After 3 months follow-up, HbA1c, fasting glucose, C-reactive protein(CRP), UACR and endotrophin levels were observed to clearly reduce. The variation in serum endotrophin levels examined at the start of the study and in the 3rd month was identified to have a positive correlation with the variation in HbA1c and UACR levels (r = 0.342, p = 0.02; r = 0.484, p = 0.001). Multiple linear regression analysis showed percentage variation values (δ)-endotrophin levels were only independently correlated with (δ)-UACR (model r2 = 0.257, p value = 0.00). CONCLUSIONS: Endotrophin levels decreased significantly with the decrease in HbA1c. Unexpectedly, this reduction in endotrophin levels is closely related to the decrease in UACR, regardless of blood glucose regulation. We think that studies targeting endotrophin will contribute to the diagnosis, treatment and follow-up of diabetic nephropathy in the future.

Multilayer global longitudinal strain assessment of subclinical myocardial dysfunction related to insulin resistance.

Myocardial tissue is sensitive to insulin resistance (IR) due to its interactions with insulin levels. Previous studies demonstrated that heart failure prevalence was higher in IR patients. Evaluation of myocardial deformation by multilayer global longitudinal strain (MGLS) might provide more information about IR related left ventricular dysfunction. In this study, we aimed to investigate subclinical LV dysfunction with MGLS in patients with IR. The study was designed as a prospective cross-sectional study. The present study included 64 patients with IR (+), and 54 subjects without IR (-) prospectively. The homeostasis model of insulin resistance (HOMA-IR) was used to quantify insulin resistance. Specific analysis for endocardial, mid-myocardial and epicardial layers were performed by two-dimensional (2D) speckle tracking echocardiography (STE) for multilayer global longitudinal strain. MGLS (Endocard-Mid-myocard-Epicard) values were significantly lower in the IR (+) group compared to IR (-) group ((GLS-endocard; - 15.1 ± 1.5 vs. - 18.7 ± 1.3, p < 0.001), (GLS-mid-myocard; - 16.0 ± 2.0 vs. - 18.0 ± 2.0, p < 0.001), (GLS-epicard; - 17.0 ± 1.7 vs. - 18.01 ± 1.94, p = 0.004)). GLS-endocard levels were significantly and positively correlated with HOMA-IR levels (r = 0.643, p < 0.001). HOMA-IR and age were found to be independent factors in detecting a decrease in GLS-endocard level in regression analysis. In conclusion, our data reveal that IR (+) patients had significantly lower strain values compared to IR (-) group. Besides, we presented that the HOMA-IR value was an independent predictor of subclinical left ventricular dysfunction.

Relationships among oncostatin M, insulin resistance, and chronic inflammation: a pilot study

ABSTRACT Objective Activated macrophages (M1-type macrophages) in adipose tissue secrete many proinflammatory cytokines that induce insulin resistance (IR). Oncostatin M (OSM), a member of the interleukin-6 (IL-6) family of Gp130 cytokines, plays an important role in a variety of biological functions, including the regulation of inflammatory responses. Proinflammatory cytokines released in patients with IR trigger a chronic, low-grade inflammatory reaction in blood vessel walls. This inflammator response leads to endothelial damage, which is the main mechanism for atherosclerosis and many cardiovascular diseases. Animal studies have reported a relationship between OSM and IR. To the best of our knowledge, however, few clinical studies have examined this topic. Therefore, we studied the relationship between serum levels of OSM and IR. Subjects and methods This prospective cross-sectional case-control study enrolled 50 people with IR (according to the HOMA-IR and QUICKI indices) and 34 healthy controls. The fasting blood concentrations of insulin, glucose, blood urea nitrogen (BUN), creatinine, aspartate aminotransferase (AST), alanine aminotransferase (ALT), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglyceride, total cholesterol, C-reactive protein (CRP), and OSM were determined. Results There were no significant differences between the two groups in age, sex, and HbA1c levels. Univariate analyses showed that waist circumference (WC) and levels of fasting glucose, insulin, CRP, HDL-C, OSM, HOMA-IR, and QUICKI differed between the two study groups. In multivariate analyses, both IR indices (QUICKI and HOMA) and OSM differed between the two groups. Conclusion OSM was correlated with the IR indices (QUICKI and HOMA). For simplicity, it might replace the other IR indices in the future. Further detailed studies are needed to confirm this.

Serum endotrophin levels in patients with heart failure with reduced and mid-range ejection fraction.

BACKGROUND: Endotrophin, a type VI collagen cleavage product, has fibrosis, and insulin resistance effects. Type VI collagen also plays a role in cardiac fibrosis. In this study, we aimed to investigate the role of endotrophin in the pathogenesis of cardiac fibrosis by determining its levels in patients with heart failure with reduced and mid-range ejection fraction (EF). We also aimed to determine the possible association between endotrophin and treatment that prevents ventricular fibrosis. METHODS: Sixty patients with heart failure with reduced and mid-range EF and 27 volunteers with no cardiac failure were included in this study. In both groups, biochemical tests, EF, and endotrophin levels were measured. ELISA was performed for the determination of endotrophin levels. RESULTS: When compared with the control group, there was no significant difference for endotrophin levels in the patient group (p = .35). Participants in the study were divided into two groups according to their EFs, 40% and less, and 40-49%. They were classified according to their use of renin-angiotensin-aldosterone system (RAAS) blocking drugs. Endotrophin levels were significantly lower in patients with mid-range EFs between 40 and 49% (p = .03) using RAAS blockers. CONCLUSION: This study is the first to evaluate the relationship between endotrophin and heart failure. Endotrophin levels were found to be low in patients with heart failure with mid-range EF who were using RAAS blockers. This suggests that RAAS blockers may influence endotrophin levels and thus could have a role in the prevention of remodelling.

Serum Adropin Levels Are Reduced in Adult Patients with Nonalcoholic Fatty Liver Disease.

OBJECTIVES: Adropin is a novel marker of metabolic syndrome and insulin resistance. The aim of this study was to explore the association of serum adropin levels with hepatosteatosis among adult patients. MATERIALS AND METHODS: Serum biochemical parameters including liver and renal function tests, insulin levels, and serum adropin levels were compared between adult patients with nonalcoholic fatty liver disease (NAFLD) and healthy control cases. RESULTS: A total of 51 patients with a mean age of 37.9 ± 9.96 years diagnosed with grade 2-3 hepatosteatosis and 30 healthy control cases with a mean age of 34.8 ± 9.5 years were included in the study. Serum adropin levels in the NAFLD group were statistically significantly lower than in the control cases (588.4 ± 261.0 vs. 894.2 ± 301.2, respectively; p < 0.001). The study participants were further subdivided into 2 groups as patients with (n = 35) or without (n = 46) insulin resistance using the serum homeostatic model of assessment-insulin resistance (HOMA-IR). Serum adropin levels were statistically significantly lower in patients with insulin resistance (p < 0.01). There was a negative correlation between adropin levels and serum insulin, HOMA-IR, urea, gamma-glutamyl transferase, total cholesterol, and triglyceride levels. CONCLUSION: We observed a decrease in serum adropin levels among adult patients with NAFLD. We also found lower levels of serum adropin in patients with insulin resistance, supporting previous data in the literature. Studies investigating the association of adropin levels with other inflammatory parameters are warranted to define its exact role in the pathogenesis of hepatosteatosis.

Serum Angiopoietin-like peptide 4 levels in patients with hepatic steatosis.

OBJECTIVES: Angiopoietin-like peptide 4 (ANGPTL-4) plays an important role in lipid metabolism by inhibiting the enzyme lipoprotein lipase. This effect of ANGPTL-4 results in suppression of the release of plasma triglyceride-derived fatty acids. Increase in fatty acid levels entering to the liver and abnormalities in their secretion is one of the main mechanisms in pathogenesis of hepatic steatosis. In this study, we aimed to investigate the role of ANGPTL-4 in pathogenesis of hepatic steatosis by determining its levels in patients with fatty liver disease. METHODS: Totally 51 patients (age: 37.9 ±â€¯9.9 years, M/F) diagnosed with grade 2-3 hepatic steatosis with ultrasound and 30 healthy volunteers (age: 34.8 ±â€¯9.5 years, M/F) were included in the study. In both groups, routine biochemical tests including fasting blood glucose, fasting insulin levels, triglyceride, total cholesterol, LDL- cholesterol, HDL-cholesterol, AST, ALT, ALP, GGT levels were measured together with the ANGPTL-4 levels. In determination of ANGPTL-4 levels, ELISA was performed. RESULTS: When compared with the control group, ANGPTL-4 levels were determined to be decreased in patients with hepatic steatosis (369 ±â€¯243 vs 303 ±â€¯286 ng/mL, p = 0.014). There was a negative weak correlation observed between ANGPTL-4 and triglyceride levels (r = -0.246, p = 0.027). Among all groups, when patients with and without insulin resistance were compared; ANGPTL-4 levels were determined to be similar. While fasting blood glucose levels were similar between 2 groups; fasting insulin and triglyceride levels were determined to be increased in hepatic steatosis group (Insulin 17.7 ±â€¯12 vs 7.4 ±â€¯3.3 µIU/mL, p < 0.001, triglyceride 158 ±â€¯46.4 vs 118 ±â€¯59.8 mg/dL p < 0.001). CONCLUSIONS: We have determined lower serum ANGPTL-4 levels in patients with hepatic steatosis. ANGPTL-4 that is regulating LPL activity plays an important role in fatty liver disease pathogenesis via free fatty acid metabolism and peroxisome proliferator-activated receptor-delta (PPAR-δ). We believe that the results of this study would elucidate the investigations about the mechanism of fatty liver disease development and treatments targeting ANGPTL-4.

Choice of treatment based on Turkish hypertension consensus report: Do we follow the recommendations?

OBJECTIVE: The aim of this study was to determine how often the recommendations of the Turkish Hypertension Consensus Report are followed, and to draw attention to the report. METHODS: The demographic information of 1000 patients diagnosed with hypertension and the details of the antihypertensive medications prescribed at the outpatient service of a tertiary care hospital were recorded, and the data were compared with the recommendations of the report. RESULTS: The mean age of the patients was 62±11 years. In all, 623 (62.3%) of the 1000 patients were women, and 377 (37.7%) were men. A combination of an angiotensin II receptor blocker (ARB) and a diuretic was the most frequently observed prescription. A diuretic was the most used antihypertensive drug (58.7%), followed by an ARB (48.8%). However, as a monotherapy, a calcium channel blocker (CCB) was the most commonly used antihypertensive drug (19.2%). The most frequently used antihypertensive drug group in older patients was diuretics (63.6%), as proposed in the report. Beta blockers (49.1%) were used more often than expected. For the diabetic group also, a diuretic (60.7%) was the most frequently used antihypertensive drug, followed by an ARB (51.1%) and a CCB (45.2%). Angiotensin-converting enzyme (ACE) inhibitors (34.6%) were the fifth most preferred antihypertensive drug class. However, when ACE inhibitors and ARBs were considered as a single group, known as renin-angiotensin system (RAS) blockers, these RAS blockers were the most prescribed antihypertensive drug class, followed by diuretics. In the group of patients with coronary artery disease, treatment was found to be generally consistent with the report, but the use of diuretics was greater than expected. Lastly, 124 of 160 patients who had chronic kidney disease were given RAS blocker therapy, which was in line with the consensus report recommendations. CONCLUSION: Antihypertensive therapies were individualized, as suggested by the consensus report. However, there are proposals still to be considered in special patient groups.

The Effects of Blood Glucose Regulation in Omentin-1 Levels among Diabetic Patients.

Objectives: Omentin-1, an adipocytokine that increases the insulin sensitivity, has been determined to be reduced in patients with insulin resistance, impaired glucose tolerance, and Type-2 diabetes mellitus. In this study, we have investigated the alterations in Omentin-1 levels with the blood glucose regulation in diabetic patients having poor glycemic control. By this way, we aimed to determine the role of Omentin-1 as a marker in follow-up and monitoring progression of diabetes. Methods: Totally 58 patients with type 2 diabetes mellitus, older than 18 years of age who were having poor glycemic control (HbA1c≥9) were included in this study. In the first visit, all clinical and biochemical parameters of patients were recorded. After baseline evaluation, the patients were advised life style changes, and their medical treatment was determined individually according to the recommendations of the American Diabetes Association guidelines. At the end of the third month patients were re-evaluated. Serum Omentin-1 levels were measured with ELISA. Results: In patients using only oral antidiabetic agents, after exchanging the treatment with insulin, on 3rd month of treatment, there was a significant decrease in serum C-peptide and Omentin-1 levels compared with the initial results (p=0.034, p=0.048, respectively). On the other hand, in patients using insulin treatment from the beginning of the study, there was not any significant alterations in serum C-peptide or Omentin-1 levels compared with the initial results (p>0.05). Conclusions: Serum Omentin-1 levels may change with insulin and metformin treatments in Type-2 diabetic patients. In patients with poor glycemic control, Omentin-1 levels do not change with the regulation of blood glucose levels. A decrease in Omentin-1 and C-peptide levels has been determined after the initiation of insulin therapy. This suggests that, Omentin-1 levels are closely associated with the endogenous insulin reserve and may be used in follow-up of patients.

A cross-sectional study to evaluate metabolic and demographic factors affecting cognitive function among low educated internal medicine outpatients.

OBJECTIVE: To evaluate factors affecting cognitive function in internal medicine outpatients. METHODS: A total of 130 consecutive outpatients aged 50-80 years old were included in this cross-sectional study conducted at Okmeydani Training and Research Hospital, Istanbul, Turkey between March and May 2013. Cognitive function was evaluated via Standardized Mini-Mental State Examination (SMMSE) scores. Logistic regression analysis was performed to determine factors predicting poor cognitive function. RESULTS: Mild-to-moderate cognitive impairment was noted in 39.2% of the patients. Median (interquartile range) total SMMSE scores were significantly higher in patients aged 60 years (27.0 (2.0) vs. 25.0 (5.0), p=0.000). Multivariate linear regression analyses revealed female gender (B, -1.27; 95% CI, -2.36 to -0.18; p=0.023) and aging (B, -0.20; 95% CI, -0.26 to -0.14; p<0.001) to result in a significant decrease in the total SMMSE scores. CONCLUSION: Mild-to-moderate cognitive impairment was observed in 39.2% of internal medicine outpatients. Old age and female gender were significant predictors of lower total SMMSE scores. Furthermore, besides for high language scores in hypertensive patients on combined therapy, no significant impact of hypertension or obesity was observed on the SMMSE scores.

Effect of Glycemic Regulation on Endocan Levels in Patients With Diabetes: A Preliminary Study.

Endothelial-specific molecule 1 (endocan) is expressed by endothelial cells and may have a major role in the regulation of cell adhesion and in the pathogenesis of inflammatory disorders. We aimed to assess change in endocan levels after 3 months of lifestyle change recommendations and guideline-based treatment. Diabetic patients (n = 77) who had neither chronic kidney disease nor chronic inflammatory disease were included. After baseline evaluation, the patients were advised lifestyle changes, and their medical treatment was determined individually according to recommendations of the American Diabetes Association (ADA) guidelines. At the end of third month patients were reevaluated. Baseline endocan levels were significantly increased in the study group compared with the control group. The third-month laboratory workup showed significant reductions in hemoglobin A1c, urinary albumin-to-creatinine ratio (UACR), and endocan levels. Only δ-UACR was independently correlated with δ-endocan in multivariate linear regression analysis. Our findings suggest that serum endocan concentrations are elevated in patients with type 2 diabetes and decrease following anti-hyperglycemic treatment. Furthermore, decrease in endocan concentrations might be associated with improved glycemic control and reductions in UACR.

Evaluation of malnutrition with blood ghrelin and fecal elastase levels in acute decompensated heart failure patients.

OBJECTIVES: Exocrine pancreatic dysfunction may contribute to malnutrition and lack of appetite in the advanced stages of heart failure. Nutritional assessment was carried out on patients diagnosed with mild or moderate/severe heart failure. Fecal elastase levels are an indicator of pancreatic exocrine function and ghrelin is an appetite hormone which is also investigated for its contribution to malnutrition. STUDY DESIGN: This is an observational study. 52 patients (32 males, 20 females) aged over eighteen years and hospitalized for acute decompensated heart failure (ADHF) were included in the study. They were compared with 31 people (16 male, 15 female) of the same age as Control Group (C). Patients in New York Heart Association (NYHA) stages 1 and 2 were grouped as mild (miADHF), while those in NYHA stages 3 and 4 were grouped as moderate/severe ADHF (seADHF). Fecal and blood samples were taken at admission. In ADHF patients, exocrine pancreatic functions and their relationship with malnutrition were evaluated. Statistical analyses were performed using Tukey's test, the independent-sample t-test, the Kruskal-Wallis test, the Mann-Whitney U-test, the chi-square test and Pearson's bivariate correlation analysis. RESULTS: Significantly decreased fecal elastase levels were found when moderate/severe ADHF patients and the control group were compared. (C 278.9±144.8, miADHF 336.6±181.7, seADHF 168.7±153.6, p=0.002). 10 seADHF patients (50%) had severe, 4 (20%) moderate, and 6 (30%) mild pancreatic insufficiency. Ghrelin levels were higher in seADHF patients compared to C and miADHF patients (C 69.7±34.6, miCHF 82.5±48.2, SeADHF 105.0±78.1 p=0.361). CONCLUSION: Fecal elastase and ghrelin hormone levels can contribute to the determination of malnutrition in ADHF patients.
