Urinary and circulatory netrin-1 as biomarker in diabetes and its related complications: a systematic review and meta-analysis. Endocrine 2024; 84:328-344. [PMID: 37996774 DOI: 10.1007/s12020-023-03598-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 10/30/2023] [Indexed: 11/25/2023]
Abstract
BACKGROUND Novel biomarkers have been suggested for the diagnosis and prognosis of diabetes mellitus. The biomarker utility of netrin-1 in diabetes as an extracellular protein has been investigated. In this systematic review and meta-analysis, we reviewed the role of netrin-1 as a biomarker in prediabetes, diabetes, and complications of diabetes. METHODS PubMed, Embase, Scopus, and Web of Science were systematically searched for studies that measured circulatory and/or urinary netrin-1 levels in diabetes and compared them with non-diabetic patients or evaluated the prognostic role of this marker. Standardized mean difference (SMD) and 95% confidence interval (CI) were calculated using random-effect meta-analysis to compare netrin-1 levels between groups. The impact of mean age, male sex percentage, sample size, mean body mass index, and publication year on the overall heterogeneity was assessed using meta-regression. RESULTS Among 413 records from international databases, 19 original studies were included with 2061 cases (1137 diabetics, 196 prediabetics, and 728 healthy controls). Meta-analysis of eight studies measuring netrin-1 in patients with diabetes and comparing it with healthy controls showed no significant difference between the two groups (SMD 0.69, 95% CI -0.78 to 2.16, I2 = 98%, p-value = 0.36). On the other hand, a meta-analysis of netrin-1 levels in patients with prediabetes in comparison with healthy controls revealed that they had lower levels (SMD -0.51, 95% CI -0.81 to -0.21, p-value < 0.01). Diabetic patients with microalbuminuria and macroalbuminuria had significantly higher circulatory netrin-1 levels compared to normoalbuminuric group SMD 1.18, 95% CI 0.83 to 1.53, p-value < 0.01 and SMD 1.67, 95% CI 0.76 to 2.58, p-value < 0.01, respectively). Moreover, no difference in urinary netrin-1 levels was found between micro-, macro-, and normoalbuminuric groups (p-value > 0.05). CONCLUSION Netrin-1 showed promising results as a biomarker in diabetes prognosis. However, more studies are required to confirm our findings, and higher sample size studies are needed to evaluate the diagnostic utility of this marker.

Circulatory resistin levels in inflammatory bowel disease: a systematic review and meta-analysis. BMC Gastroenterol 2024; 24:107. [PMID: 38486190 PMCID: PMC10941394 DOI: 10.1186/s12876-024-03199-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Accepted: 03/11/2024] [Indexed: 03/17/2024] Open
Abstract
BACKGROUND Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic relapsing-remitting systemic disease of the gastrointestinal tract with rising incidence. Studies have shown that adipocytes play a crucial role in patients with IBD by actively participating in systemic immune responses. The present study was designed to investigate the correlation between the circulatory levels of resistin, as an adipokine, and active and remission phases of IBD in comparison with healthy controls. METHODS Relevant articles were retrieved from PubMed, Embase, the Web of Science, and Scopus from inception until June 2023. Estimation of the standardized mean difference (SMD) and 95% confidence interval (CI) for comparison of plasma/serum resistin levels between IBD patients, patients in remission, and healthy controls were conducted through random-effect meta-analysis. RESULTS A total of 19 studies were included, assessing 1836 cases. Meta-analysis indicated that generally, serum/plasma resistin levels were higher in IBD patients in comparison with healthy controls (SMD 1.33, 95% CI 0.58 to 2.08, p-value < 0.01). This was true for each of the UC and CD separate analyses, as well. Moreover, it was shown that higher serum/plasma resistin levels were detected in the active phase of IBD than in the remission phase (SMD 1.04, 95% CI 0.65 to 1.42, p-value = 0.01). Finally, higher serum/plasma resistin levels were found in the remission phase compared to healthy controls (SMD 0.60, 95% CI 0.15 to 1.06, p-value < 0.01). CONCLUSION The results of this systematic review and meta-analysis support the conclusion that circulating resistin levels are increased in IBD (both UC and CD). Also, higher resistin levels were recorded in the remission phase of IBD in comparison with healthy controls. This indicates that further studies may provide valuable insights into the role of resistin in the pathogenesis of IBD.

Abstract
Type 2 diabetes mellitus (T2DM) is caused by an interplay of various factors where chronic hyperglycemia and inflammation have central role in its onset and progression. Identifying patient groups with increased inflammation in order to provide more personalized approach has become crucial. We hypothesized that grouping patients into clusters according to their clinical characteristics could identify distinct unique profiles that were previously invisible to the clinical eye. A cross-sectional record-based study was performed at the Primary Health Care Center Podgorica, Montenegro, on 424 T2DM patients aged between 30 and 85. Using hierarchical clustering patients were grouped into four distinct clusters based on 12 clinical variables, including glycemic and other relevant metabolic indicators. Inflammation was assessed through neutrophil-to-lymphocyte (NLR) and platelet to lymphocyte ratio (PLR). Cluster 3 which featured the oldest patients with the longest T2DM duration, highest hypertension rate, poor glycemic control and significant GFR impairment had the highest levels of inflammatory markers. Cluster 4 which featured the youngest patients, with the best glycemic control, the highest GFR had the lowest prevalence of coronary disease, but not the lowest levels of inflammatory markers. Identifying these clusters offers physicians opportunity for more personalized T2DM management, potentially mitigating its associated complications.

Effect of tirzepatide on albuminuria levels and renal function in patients with type 2 diabetes mellitus: A systematic review and multilevel meta-analysis. Diabetes Obes Metab 2024; 26:1090-1104. [PMID: 38116693 DOI: 10.1111/dom.15410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 11/20/2023] [Accepted: 11/29/2023] [Indexed: 12/21/2023]
Abstract
AIM The present systematic review aimed to summarize the available evidence from published randomized controlled trials (RCTs) regarding the effect of tirzepatide on albuminuria levels and renal function in patients with type 2 diabetes mellitus. MATERIALS AND METHODS Medline (via PubMed), Cochrane Library and Scopus were searched until 20 October 2023. Double-independent study selection, data extraction and quality assessment were performed. Evidence was pooled with a three-level mixed-effects meta-analysis. RESULTS In total, 9533 participants from eight RCTs were analysed. All RCTs had a low risk of bias, according to the Cochrane Collaboration tool (RoB2). Tirzepatide was associated with a significantly greater reduction in urine albumin-to-creatinine ratio compared with controls [mean difference (MD) -26.9%; 95% confidence interval (CI) (-34.76, -19.04); p < .001; level of evidence (LoE) moderate]. This effect remained significant in participants with baseline urine albumin-to-creatinine ratio ≥30 mg/g [MD -41.42%; 95% CI (-54.38, -28.45); p < .001; LoE moderate]. Based on subgroup analysis, the comparative effect of tirzepatide was significant against placebo and the insulin regimen, whereas no difference was observed compared with semaglutide. The beneficial effect of tirzepatide on albuminuria levels remained significant across all investigated doses (5, 10 and 15 mg), showing a dose-response relationship. A neutral effect was observed on the estimated glomerular filtration rate [MD 0.39 ml/min/1.73m2 ; 95% CI (-0.64, 1.42); p = .46; LoE moderate]. CONCLUSION Our findings suggest that tirzepatide probably leads to a significant reduction in albuminuria across all administered doses, while its use is associated with a neutral effect on creatinine clearance as a measure of renal function.

Abstract
Various studies have reported the association between cardiac markers and hepatic disorders. The main objective of this review article was to elucidate the significance of important cardiac indicators such as ischemia-modified albumin, cardiac troponin, cardiac natriuretic peptides, creatine kinase, creatine kinase-MB, lactate dehydrogenase, heart-type fatty acid-binding protein, osteopontin, soluble suppression of tumorigenicity 2, C-reactive protein, and lipoprotein(a) in the development of hepatic disorders. In addition, it highlighted recent notable discoveries and accomplishments in this field and identified areas requiring further investigation, ongoing discussions, and potential avenues for future research. Early identification and control of these cardiac markers might be helpful to control the prevalence of hepatic disorders associated with cardiovascular diseases.

Abstract
The prevalence of both atrial fibrillation (AF) and diabetes is increasing day by day and commonly co-exist with a longer duration of diabetes and poor control, putting the individual at higher risk of AF. This review article presented some traditional and novel biomarkers related to AF in patients with diabetes mellitus. The literature review employed several databases, including Google Scholar, PubMed, and Science Direct. The investigation was finished on October 30, 2023. Many terms are utilized, including "AF", "Biomarkers", "Diabetes Mellitus", and "Pathogenesis". There are numerous biomarkers of diabetes, but this review article reports only leptin, adiponectin, glycated hemoglobin, ceramide, ferritin, fibrinogen, hematological indices, interleukin-18, thrombospondin 1, acylcarnitine, plasminogen activator inhibitor-1 and triglycerides and high-density lipoprotein cholesterol, since those biomarkers play a significant role in the pathogenesis of AF. However, no data was found, including fructosamine, glycated albumin, 1,5 anhydroglucitol, fetuin-A, α-hydroxybutyrate, mannose-binding lectin serine peptidase, transferrin, IL-1 receptor antagonist in AF. Understanding the interplay between diabetes and AF through the measurement of relevant biomarkers can contribute to better risk assessment, early detection, and the development of targeted therapeutic strategies for individuals at risk or already affected by these conditions.

Abstract
Acute pancreatitis (AP) is a common inflammatory state characterized by a clinical course that can lead to serious local and extrapancreatic organ malfunction and failure. Interleukins (ILs) are biologically active glycoproteins primarily produced by macrophages and lymphocytes. According to the literature, there are many ILs. However, this article represents a summary of the role of ILs in AP, such as IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-11, IL-12, IL-13, IL-14, IL-15, IL-16, IL-17, IL-18, IL-19, and IL-20. The ways to modulate IL activity to reduce inflammation and improve outcomes in individuals with this condition are under investigation. Drugs that target specific ILs might be developed to mitigate the effects of AP.

Abstract
Aim: Studies that explored endocan (as a novel marker of endothelial dysfunction) in relation to metabolic syndrome (MetS) are scarce and show discordant results. Importantly, no study has yet examined serum endocan levels in exclusively postmenopausal women with MetS and free of diabetes. Oxidative stress and inflammation are the key features of MetS and consequently cardiovascular diseases. Hence, we aimed to explore the potential relationship between endocan, oxidative stress [i.e., determined by total antioxidant status, total oxidant status, and pro-oxidant/antioxidant balance (PAB)], inflammation, and MetS in a cohort of postmenopausal women. Methods: A total of 126 postmenopausal women were included consecutively. MetS was diagnosed following the International Diabetes Federation criteria. Results: Higher serum endocan levels were found in MetS group as compared with MetS-free counterparts [6.03 (3.47-10.37) pg/mL vs. 2.27 (1.49-3.50) pg/mL, P < 0.001]. Endocan showed good discriminatory ability toward MetS [area under the curve (AUC) = 0.809]. Besides age, the inclusion of oxidative stress and inflammation biomarkers, such as PAB and high-sensitivity C-reactive protein (hsCRP), the AUC for discrimination postmenopausal women with MetS from MetS-free women was 0.845. Conclusion: Postmenopausal women with MetS exhibited almost 2.7 times higher serum endocan level as compared with MetS-free middle-aged women. Endocan showed good discriminatory ability toward MetS and could be a diagnostic marker in MetS. Similar results were confirmed when added an age, oxidative stress, and inflammation biomarkers (i.e., PAB and hsCRP) were included for the discrimination of postmenopausal with MetS from MetS-free women.

Abstract
AIMS The present systematic review aimed to synthesize available data from recently published randomized trials (RCTs) investigating the efficacy and safety of the novel, orally administered, small-molecule glucagon-like peptide 1 receptor agonists (GLP-1RAs) orforglipron and danuglipron for the treatment of type 2 diabetes mellitus (T2DM), obesity or both. METHODS Literature search was performed through Medline (via PubMed), Cochrane Library and Scopus until August 16, 2023. Double-independent study selection, data extraction and quality assessment were performed. Evidence was pooled with random effects meta-analysis. RESULTS Totally, 1037 patients among seven RCTs were analyzed. All RCTs had low risk of bias according to the Cochrane Collaboration tool (RoB2). Novel GLP-1RAs led to significant reduction in HbA1c in patients with T2DM compared to controls (MD = -1.03 %; 95 % CI = [-1.29, -0.77]; P < 0.001). A significantly greater weight reduction was also noted both in patients with T2DM or obesity compared to controls (MD = -3.26 kg; 95 % CI = [-4.79, -1.72]; P < 0.001 and MD = -7.52 kg; 95 % CI = [-14.63, -0.41]; P = 0.038, respectively; P for subgroup differences = 0.25). Regarding safety, novel GLP-1RAs showed a neutral effect on the odds of severe hypoglycemia or serious adverse events (OR = 0.34; 95 % CI = [0.09, 1.31]; P = 0.11 and OR = 0.95; 95 % CI = [0.39, 2.34]; P = 0.91, respectively) and significantly higher odds of gastrointestinal, treatment-emergent adverse events (OR = 2.57; 95 % CI = [1.49, 4.42]; P < 0.001) and adverse events leading to discontinuation (OR = 2.89; 95 % CI = [1.22, 6.87]; P = 0.016). CONCLUSION Preliminary evidence supports that orforglipron and danuglipron are efficient in glycemic control and weight reduction in T2DM, obesity or both. More longitudinal research is warranted in order to provide deeper insights into their efficacy, safety and tolerability before their potential incorporation in the pharmacological arsenal against T2DM or obesity.

Abstract
Cardiovascular disease (CDV) represents the major cause of death globally. Atherosclerosis, as the primary cause of CVD, is a chronic immune-inflammatory disorder with complex multifactorial pathophysiology encompassing oxidative stress, enhanced immune-inflammatory cascade, endothelial dysfunction, and thrombosis. An initiating event in atherosclerosis is the subendothelial accumulation of low-density lipoprotein (LDL), followed by the localization of macrophages to fatty deposits on blood vessel walls, forming lipid-laden macrophages (foam cells) that secrete compounds involved in plaque formation. Given the fact that foam cells are one of the key culprits that underlie the pathophysiology of atherosclerosis, special attention has been paid to the investigation of the efficient therapeutic approach to overcome the dysregulation of metabolism of cholesterol in macrophages, decrease the foam cell formation and/or to force its degradation. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a secretory serine proteinase that has emerged as a significant regulator of the lipid metabolism pathway. PCSK9 activation leads to the degradation of LDL receptors (LDLRs), increasing LDL cholesterol (LDL-C) levels in the circulation. PCSK9 pathway dysregulation has been identified as one of the mechanisms involved in atherosclerosis. In addition, microRNAs (miRNAs) are investigated as important epigenetic factors in the pathophysiology of atherosclerosis and dysregulation of lipid metabolism. This review article summarizes the recent findings connecting the role of PCSK9 in atherosclerosis and the involvement of various miRNAs in regulating the expression of PCSK9-related genes. We also discuss PCSK9 pathway-targeting therapeutic interventions based on PCSK9 inhibition, miRNA levels manipulation by therapeutic agents, and the most recent advances in PSCK9 gene editing using CRISPR/Cas9 platform, meganuclease, and base editors.

Abstract
OBJECTIVE Although it is assumed that novel-derived anthropometric indices can better reflect cardiometabolic risk than traditional ones, the results are conflicting. Previous studies have mainly focused on patients with type 2 diabetes mellitus. However, studies conducted on populations with prediabetes are scarce. The present study aimed to examine the potential relationship between prediabetes and novel anthropometric parameters [that is, cardiometabolic index (CMI), visceral adiposity index (VAI), lipid accumulation product index (LAP), body roundness index (BRI), and body adiposity index (BAI)] and traditional parameters [that is, waist circumference (WC), hip circumference (HC), body mass index (BMI), waist-to-height ratio (WHtR), and waist-to-hip ratio (WHR)] in adults with prediabetes. PATIENTS AND METHODS This case-control cross-sectional study included 177 patients with prediabetes and 609 control subjects. Biochemical and simple anthropometric parameters were measured (WC, HC, body weight, and height), whereas the other parameters were calculated. RESULTS WC, CMI, VAI, and LAP independently correlated with prediabetes. Principal component analysis (PCA) was used to extract several factors that correlated with prediabetes. Significant predictive capability was demonstrated for non-traditional anthropometric/lipid-related factors and WHipR-related factors for prediabetes (OR=1.334 and OR=1.202, respectively). However, only non-traditional anthropometric/lipid-related factors (i.e., VAI, CMI, and LAP) demonstrated an independent significant positive relationship with prediabetes in multivariate binary regression analysis. CONCLUSIONS CMI, VAI, and LAP could be superior to BAI, BRI, and conventional anthropometric parameters for discriminating patients with prediabetes in the adult population. Prospective trials are needed to confirm our results.

Abstract
Aim: There are no studies regarding comparative analysis of serum biomarkers of oxidative stress in patients with psoriasis (PsO) and atopic dermatitis (AD). We aimed to compare the serum redox homeostasis parameters in patients with PsO vs. AD in an attempt to find the sensitive and specific oxidative stress biomarker that could best reflect the existence of one of these disease entities. Methods: Forty patients with PsO and forty patients with AD were consecutively included in this cross-sectional study. Parameters of redox homeostasis, i.e., pro-oxidants [malondialdehyde (MDA) and advanced oxidation protein products (AOPP)] and antioxidants [catalase (CAT) and superoxide dismutase (SOD)] were determined. Results: There was no difference in oxidative stress biomarkers between the PsO and AD group, except for higher CAT activity in the AD group (p < 0.001). Among all examined redox homeostasis biomarkers, ROC analysis showed that only CAT exhibited good diagnostic accuracy (AUC = 0.719) in the discrimination of patients with PsO vs. AD, with 0.436 U/L as the cut-off value of CAT activity. Conclusions: The CAT exhibited good diagnostic accuracy in the discrimination of patients with AD from those with PsO. The obtained results could suggest the importance of the use of antioxidants as a potential therapeutic strategy in the treatment of these two skin inflammatory diseases.

Abstract
OBJECTIVE Previous studies suggested that ethnic differences, sex and obesity could modify the relationship between 25-hydroxyvitamin D [25(OH)D], glycometabolic markers and/or type 2 diabetes mellitus (T2D). We aimed to examine the potential relationship between [25(OH)D] and T2D in postmenopausal women in Montenegro. In addition, we aimed to explore if a set of biomarkers, rather than [25(OH)D] as a single biomarker, could better explain its potential association with T2D. PATIENTS AND METHODS A total of 116 postmenopausal, otherwise healthy women and 48 postmenopausal women with T2D were included. Univariable and multivariable binary logistic regression analysis, along with principal component analysis (PCA), were applied to test the associations between examined biomarkers/set of biomarkers with T2D. RESULTS Women with T2D had lower serum [25(OH)D] levels than healthy controls (p = 0.024). No independent relationship between [25(OH)D] and T2D was found. PCA extracted three significant factors that were associated with T2D, i.e., age-glycometabolic-related factor (i.e., with positive loadings of age, glucose and insulin; OR = 11.321, p < 0.001), obesity-inflammation- related factor (i.e., with positive loadings of hsCRP and WC, and negative loading of [25(OH)D]; (OR = 2.079, p < 0.001)) and lipid-related factor (i.e., with positive loadings of TG and LDL-c, and negative loading of HDL-c; OR = 1.423, p = 0.044). CONCLUSIONS The relationship between [25(OH)D] and T2D is modulated by central obesity (as measured by WC) and inflammation (as measured with hsCRP) in postmenopausal women. Their joint measurement, rather than [25(OH)D] itself, could provide better information for the risk assessment for T2D in postmenopausal women.

Redox Status and Telomere-Telomerase System Biomarkers in Patients with Acute Myocardial Infarction Using a Principal Component Analysis: Is There a Link? Int J Mol Sci 2023; 24:14308. [PMID: 37762611 PMCID: PMC10531660 DOI: 10.3390/ijms241814308] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 09/09/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023] Open
Abstract
In the present study, we examined redox status parameters in arterial and venous blood samples, its potential to predict the prognosis of acute myocardial infarction (AMI) patients assessed through its impact on the comprehensive grading SYNTAX score, and its clinical accuracy. Potential connections between common blood biomarkers, biomarkers of redox status, leukocyte telomere length, and telomerase enzyme activity in the acute myocardial infarction burden were assessed using principal component analysis (PCA). This study included 92 patients with acute myocardial infarction. Significantly higher levels of advanced oxidation protein products (AOPP), superoxide anion (O2•-), ischemia-modified albumin (IMA), and significantly lower levels of total oxidant status (TOS) and total protein sulfhydryl (SH-) groups were found in arterial blood than in the peripheral venous blood samples, while biomarkers of the telomere-telomerase system did not show statistical significance in the two compared sample types (p = 0.834 and p = 0.419). To better understand the effect of the examined biomarkers in the AMI patients on SYNTAX score, those biomarkers were grouped using PCA, which merged them into the four the most contributing factors. The "cholesterol-protein factor" and "oxidative-telomere factor" were independent predictors of higher SYNTAX score (OR = 0.338, p = 0.008 and OR = 0.427, p = 0.035, respectively), while the ability to discriminate STEMI from non-STEMI patients had only the "oxidative-telomere factor" (AUC = 0.860, p = 0.008). The results show that traditional cardiovascular risk factors, i.e., high total cholesterol together with high total serum proteins and haemoglobin, are associated with severe disease progression in much the same way as a combination of redox biomarkers (pro-oxidant-antioxidant balance, total antioxidant status, IMA) and telomere length.

Comparative Study of Hematological Parameters and Biomarkers of Immunity and Inflammation in Patients with Psoriasis and Atopic Dermatitis. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1622. [PMID: 37763741 PMCID: PMC10535769 DOI: 10.3390/medicina59091622] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 09/03/2023] [Accepted: 09/04/2023] [Indexed: 09/29/2023]
Abstract
Background and Objectives: There are no studies regarding comparative analysis of hematological parameters in patients with psoriasis (PsO) and atopic dermatitis (AD), whereas studies examining serum biomarkers of immunity and inflammation in these entities are scarce and contradictory. We aimed to compare such parameters in patients with PsO and AD. Materials and Methods: Patients with PsO (n = 40) and AD (n = 40) were consecutively included in this cross-sectional study. Hematological parameters and biomarkers of immunity and inflammation (interferon-gamma (IFN-γ), interleukine (IL)-22 and C-reactive protein (CRP)) were determined. Results: While the mean corpuscular volume (MCV) was higher in the PsO group vs. the AD group (p < 0.05), there was no difference in the other examined parameters between groups. A higher neutrophil-to-lymphocyte ratio (NLR) was found in patients with AD > 50 years vs. patients with PsO of similar age (p < 0.05). Higher IL-22 levels were found in patients with AD < 50 years vs. patients with PsO of similar age (p < 0.05). Lower IL-22 levels were found in patients with AD > 50 years vs. patients with AD < 50 years (p < 0.05). Patients with PsO and with comorbidities had lower platelets (PLT), plateletcrit (PCT) and platelet-to-lymphocyte ratio (PLR), whereas lymphocytes, red cell distribution width-to-PLT ratio (RPR) and mean platelet volume/PLT ratio (MPR) were higher vs. PsO patients without comorbidities. Patients with AD and with comorbidities had lower PCT and PLR, whereas RPR was higher vs. AD patients without comorbidities. Conclusions: A higher pro-inflammatory state (i.e., higher NLR and IL-22) was found in AD vs. PsO in age-specific groups. A higher pro-inflammatory state (i.e., as reflected by platelet indexes) was found in both diseases with comorbidities.

Abstract
Aim: Type 2 diabetes mellitus (T2D) patients have an increased risk for cardiovascular disease (CVD). Different algorithms are used for the CVD risk quantification and United Kingdom Prospective Diabetes Study (UKPDS) score was among the most validated. Endocan is a novel endothelial dysfunction marker. The aim was to explore the potential relationship between serum endocan level and UKPDS risk engine score [which enables calculation of the 10-year risk of nonfatal and fatal coronary heart disease (eCHD) and stroke] in T2D patients. Materials and Methods: The study included a cohort of 104 patients with T2D (of them 52.8% men), with median age 66 years and body mass index (BMI) = 30.7 kg/m2. Patients were divided into: low (<15%), moderate (≥15% and <30%), and high-risk UKPDS category (≥30%). Results: In multivariable regression analysis (when adjusted for sex, BMI and/or hip circumference), endocan was the independent predictor for moderate and high estimated risks (nonfatal eCHD, fatal eCHD, and nonfatal stroke risk). In the Model for high nonfatal eCHD [areas under curve (AUC) = 0.895] and high fatal eCHD (AUC = 0.860) endocan indicated good clinical accuracy, and an excellent accuracy in discriminating patients with high risk for nonfatal stroke risk (AUC = 0.945). Conclusion: Endocan was the independent predictor for moderate and high estimated risks (i.e., nonfatal and fatal CHD and nonfatal stroke risk scores) in T2D patients. When included in models with sex and obesity indices endocan demonstrated good clinical accuracy in discriminating T2D patients with high risk for nonfatal and fatal eCHD and nonfatal stroke risk from those patients with low risk.

Abstract
OBJECTIVE There are no studies that investigated the association between red blood cell (RBC) and platelet (PLT) indices in relation to obesity in a cohort of exclusively late adolescents. Hence, we aimed to explore this potential relationship. PATIENTS AND METHODS A cohort of adolescents (n=156) aged between 16-19 years was included. Iron homeostasis parameters [i.e. RBC, hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) and red cell distribution width (RDW)] and platelet indices [i.e., PLT, mean platelet volume (MPV), plateletcrit (PCT) and platelet distribution width (PDW)] were determined on the automatic hematology analyzer. Their indexes (i.e. MCV/RBC, MCH/RBC, RDW/MCV, MPV/PLT and PDW/PCT) were calculated. RESULTS Univariate binary regression analysis showed negative associations between body mass index (BMI) and RDW, PDW, and PDW/PCT, respectively, and positive associations between BMI and MPV and PCT, respectively. However, only RDW kept the independent negative association with BMI in multivariate binary regression analysis [Odds Ratio (95% Confidence Interval)=0.734 (0.548-0.983); p=0.038]. CONCLUSIONS Lower RDW values are the independent predictor of higher BMI in the adolescent population. As a low-cost and simply measured parameter, RDW could be a useful diagnostic biomarker in young populations with overweight/obesity.

Abstract
Discovered two decades ago, endocan still represents an intriguing biomarker related to inflammation. Endocan is a soluble dermatan sulphate proteoglycan secreted by endothelial cells. Its expression is observed in tissues related to the enhanced proliferation, especially hepatocytes, lungs, kidneys, etc. Endocan has been investigated in many cardiometabolic disorders that are tightly connected with inflammation, such as type 2 diabetes mellitus, hypertension, atherosclerotic cardiovascular disease, kidney disease, obesity, polycystic ovary syndrome, metabolic syndrome, non-alcoholic fatty liver disease, etc. In this narrative, comprehensive review of the currently available literature, special attention will be paid to the role of endocan in the broad spectrum of cardiometabolic disorders. Since endocan has emerged as a novel endothelial dysfunction marker, the discovery of potential therapeutic strategies for patients with certain cardiometabolic risk factors would be of great importance to delay or even prevent the onset and progression of related complications, mainly cardiovascular.

Abstract
Objective: To our knowledge, the mutual involvement of a variety of metabolic and renal biomarkers and vitamin D (determined as 25-hydroxyvitamin D [25(OH)D]) in postmenopausal women has not been examined yet. Therefore, we aimed to explore such a relationship by a thorough statistical multimarker approach.
Patients and Methods: A total of 150 (diabetes and cardiovascular disease-free) postmenopausal women were included. Anthropometric and biochemical parameters were measured. The fatty liver index (FLI) and Homeostasis model assessment of insulin resistance (HOMA-IR) were calculated. Univariate and multivariate binary logistic regression analyses were used to test the predictions of cardiometabolic markers for [25(OH)D] status. Principal component analysis (PCA) was applied to explore the effect of examined biomarkers on [25(OH)D] status.
Results: Univariate binary regression analysis revealed positive associations between FLI and [25(OH)D] [OR=1.036 (1.020-1.052), P<0.001] and HOMA-IR with [25(OH)D] [OR=2.385 (1.601-3.551), P<0.001]. Multivariate logistic regression analysis with backward selection enabled us to find the best model consisting of two markers, i.e. FLI [OR=1.032 (1.016-1.048), P<0.001] and glucose [OR=2.167 (1.001-4.693), P=0.050] associated with the first tertile of [25(OH)D]. PCA extracted 2 significant factors: Renal function-related factor and Metabolic syndrome-related factor. Renal function-related factor [i.e. creatinine, uric acid, retinol-binding protein 4 (RBP4) and cystatin C] explained 29% of the variance. Also, Metabolic syndrome-related factor (i.e. HOMA-IR, FLI, hsCRP and fibrinogen) explained 29% of the variance of the tested parameters. Moreover, binary logistic regression analysis revealed significant positive predictive ability of both factors, i.e. Renal function-related factor and Metabolic syndrome-related factor (P=0.044 and P<0.001, respectively) towards [25(OH)D] status.
Conclusion: The joint involvement of renal function biomarkers and metabolic syndrome-related features (i.e. insulin resistance, inflammation and non-alcoholic fatty liver disease) can differentiate postmenopausal women with lower [25(OH)D] levels from other women.

Abstract
Background: Given the fact that the studies that examined oxidative stress in relation to obesity that included late adolescents are scarce and show inconclusive results we aimed to investigate a wide spectrum of nitro-oxidative stress biomarkers i.e., malondialdehyde (MDA), xanthine oxidase (XO), xanthine oxidoreductase (XOD), xanthine dehydrogenase (XDH), advanced oxidation protein products (AOPP) and nitric oxide products (NOx), as well as an antioxidative enzyme, i.e., catalase (CAT) in relation with obesity in the cohort of adolescent girls ages between 16 and 19 years old. Methods: A total of 59 teenage girls were included in this cross-sectional study. Binary logistic regression analysis was performed to examine possible associations between biochemical and nitro-oxidative stress markers and body mass index (BMI). Results: There were not significant differences between oxidative stress markers between normal weight and overweight/obese girls (i.e., AOPP, XOD, XO, XDH) and CAT, except for MDA (p<0.001) and NOx (p=0.010) concentrations which were significantly higher in overweight/obese adolescent girls. Positive associations were evident between BMI and high sensitivity C-reactive protein (hsCRP) (OR=2.495), BMI and uric acid (OR=1.024) and BMI and MDA (OR=1.062). Multivariable binary regression analysis demonstrated significant independent associations of BMI and hsCRP (OR=2.150) and BMI and MDA (OR=1.105). Even 76.3% of the variation in BMI could be explained with this Model. Conclusions: Inflammation (as measured with hsCRP) and oxidative stress (as determined with MDA) independently correlated with BMI in teenage girls.

Abstract
Background: Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are low-density lipoprotein cholesterol (LDL-C)-lowering drugs that play a critical role in lipoprotein clearance and metabolism. PCSK9i are used in patients with familial hypercholesterolemia and for the secondary prevention of acute cardiovascular events in patients with atherosclerotic cardiovascular disease (CVD). Methods: We focused on the literature from 2015, the year of approval of the PCSK9 monoclonal antibodies, to the present on the use of PCSK9i not only in the lipid field but also by evaluating their effects on metabolic factors. Results: PCSK9 inhibits cholesterol efflux from macrophages and contributes to the formation of macrophage foam cells. PCSK9 has the ability to bind to Toll-like receptors, thus mediating the inflammatory response and binding to scavenger receptor B/cluster of differentiation 36. PCSK9i lower the entire spectrum of apolipoprotein B-100 containing lipoproteins (LDL, very LDLs, intermediate-density lipoproteins, and lipoprotein[a]) in high CVD-risk patients. Moreover, PCSK9 inhibitors are neutral on risk for new-onset diabetes mellitus and might have a beneficial impact on the development of nonalcoholic fatty liver disease by improving lipid and inflammatory biomarker profiles, steatosis biomarkers such as the triglyceride-glucose index, and hepatic steatosis index, although there are no comprehensive studies with long-term follow-up studies. Conclusion: The discovery of PCSK9i has opened a new era in therapeutic management in patients with hypercholesterolemia and high cardiovascular risk. Increasingly, there has been mounting scientific and clinical evidence supporting the safety and tolerability of PCSK9i.

Abstract
OBJECTIVE Published reports describing awareness and knowledge of familial hypercholesterolemia (FH) among pediatricians are few and differ considerably across countries. We aimed to assess awareness and knowledge of the FH among pediatricians in Serbia. METHODS A web-based cross-sectional study using a self-designed questionnaire was conducted during the annual congress of the Serbian Association of Preventive Pediatrics in 2020. RESULTS A total of 141 pediatricians completed the questionnaire (response rate 16.1%). Overall, 91% of participants have knowledge about genetic inheritance of FH, 84.3% were aware of long-term health risks of FH, 77% were familiar with normal cholesterol values in children and 71% knew the FH prevalence in the general population. On the other hand, only 36.8% declared that they were familiar with international guidelines for FH drug treatment and only 26.2% declared to have patients with FH. CONCLUSION There is a substantial lack of practical clinical knowledge among Serbian pediatricians on managing children with FH. In addition, an extremely low questionnaire response rate (16.1%) suggests that most pediatricians are not aware of the clinical importance of FH in childhood.

Abstract
Context Prognostic considerations include assessing the risk of liver fibrosis in people with non-alcoholic fatty liver disease (NAFLD). Objectives This study evaluates the use of hematologic and metabolic parameters regarding liver steatosis and fibrosis scores (FLI and Fib-4) in non-obese type 2 diabetes mellitus (t2DM) patients with NAFLD. Methods Subjects underwent abdominal ultrasound examinations, and FLI and Fib-4 scores were calculated to evaluate liver steatosis and the risk of liver fibrosis non-invasively: 61 non-obese NAFLD subjects with t2DM were included in the cohort study and were divided into 2 groups depending on the t2DM treatment regimen. Results Fib-4 and WBC count demonstrated a significant inverse correlation (OR = 0.509, p = 0.007). WBC count had an R2 of 0.237, indicating that this marker could account for up to 23.7% of a variation in Fib-4. Fib-4 and FFA had positive correlation which did not achieve statistically significant prediction (OR=7.122, p=0.062). Additionally, a significant prediction of HbA1c (OR=1.536, p=0.016) and haemoglobin (OR=1.071, p=0.020) for FLI was revealed. Conclusion HbA1c and other haematological and metabolic parameters, such as haemoglobin and WBC, may be another non-invasive tool for determining whether non-obese NAFLD patients with t2DM are at risk of developing liver steatosis and fibrosis.

Abstract
OBJECTIVE To our knowledge, there are no studies that investigated the relationship between diabetes mellitus type 2 (T2D) and some novel indexes, such as monocyte/granulocyte to lymphocyte ratio (M/GLR), derived neutrophil to lymphocyte ratio (dNLR), and platelets to neutrophil ratio (PNR). The aim of this study was to examine the association between these novel indexes and glycated hemoglobin (HbA1c) in patients with prediabetes and T2D. PATIENTS AND METHODS A total of 827 participants were consecutively recruited. According to the American Diabetes Association (ADA) criteria, participants were divided into control, prediabetes, and T2D group. RESULTS White blood cell count (WBC), neutrophil count, NLR, dNLR, and M/GLR were higher in T2D patients than in the other two groups, whereas PNR was the lowest in T2D group. Lymphocyte count was higher in prediabetes and T2D patients than in control group. Multivariable ordinal regression analysis showed that WBC, neutrophil count, lymphocyte count, NLR, dNLR, and M/GLR were positively associated [OR (95% CI) 1.287 (1.191-1.390), p<0.001; 1.427 (1.275-1.594), p<0.001; 1.347 (1.130- 1.606), p=0.001; 1.350 (1.090-1.670), p=0.006; 1.662 (1.189-2.326), p=0.003; 1.275 (1.057-1.540), p=0.012, respectively] with HbA1c. However, PNR was negatively associated with HbA1c [0.987 (0.981-0.993), p<0.001]. CONCLUSIONS Novel, modified NLR indexes, such as dNLR and M/GLR were independently correlated with HbA1c. Also, PNR showed superiority over platelets (PLT) in relation to HbA1c. These novel indexes might give a significant contribution to the timely recognition of disturbances of glucose homeostasis in patients with prediabetes and overt diabetes.

Abstract
OBJECTIVE The pathophysiological mechanisms of idiopathic pulmonary fibrosis (IPF) are not well elucidated. It is assumed that oxidative stress and inflammation are the key underlying culprits for its onset and progression. To gain deeper insight into these processes, we have evaluated several oxidative stress parameters, inflammation markers [i.e., high sensitivity C-reactive protein (hsCRP), serum amyloid A1 (SAA1)], soluble programmed cell death-ligand 1 (sPD-L1), and 25-hydroxyvitamin D [25(OH)D] in IPF patients. PATIENTS AND METHODS Biochemistry analyses were done in 30 consecutive IPF patients and 30 age and gender-matched healthy control group (CG). RESULTS IPF patients had significantly higher advanced oxidation protein products (p<0.001), pro-oxidant-antioxidant balance (p=0.010), total oxidative status (p<0.001), and ischemia modified albumin (p<0.001) compared to CG. Lower total antioxidant status and total sulfhydryl groups (tSGH) and significantly higher sPD-L1, hsCRP (p<0.001 for all), SAA1 proteins (p=0.014) and [25(OH)D] severe deficiency [11.0 (9.6-15.1) nmol/L] in IPF patients compared to CG were observed. Paraoxonase 1 activity and hsCRP level were lower, while tSHG and sPD-L1 were higher in IPF patients with more severe disease (i.e., II+III stage compared to I stage, p<0.05 for all). CONCLUSIONS IPF patients are in a state of profound oxidative stress compared to healthy people. The inflammatory component of the disease was confirmed by higher hsCRP and SAA1, but lower [25(OH)D] in IPF than in healthy people. Also, higher levels of sPD-L1 in patients with IPF compared to healthy individuals suggest that sPD-L1 may have a significant role in immune response in IPF.

Abstract
In parallel with the rapid growth of obesity, there is also an increase in the prevalence of type 2 diabetes mellitus (T2D) worldwide. Due to its complications, cardiovascular diseases are the leading cause of death in those patients. In the last two decades, special attention has been given to oxidative stress and inflammation, as the underlying mechanisms related to T2D occurrence and progression. Moreover, micro-ribonucleic acids (miRNAs) as new genetic biomarkers take an important place in the investigation of different metabolic pathways of insulin signaling. In this review article, we discuss microRNA modulation with oxidative stress and inflammation in patients with T2D. Better insight into the novel potential therapeutic targets for treatment of diabetes and its complications is of utmost importance for public health.

[PMID: 34759993 PMCID: PMC8548903 DOI: 10.4103/jrms.jrms_198_18] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2018] [Revised: 05/21/2019] [Accepted: 03/18/2020] [Indexed: 11/04/2022]
Abstract
Background Various studies have reported contradictory results regarding the relationship of total bilirubin and high-sensitivity C-reactive protein levels (hsCRP) with diabetes mellitus Type 2 (DM2). Therefore, we aimed to examine which one of them could be more convenient for the estimation of DM2 risk in postmenopausal women. Materials and Methods A total of 150 healthy postmenopausal women (mean age 57[53-60] years) and 79 postmenopausal women with DM2 (mean age 66 [61-71] years) were enrolled in cross-sectional study. Examinees were recruited consecutively in the study during their regular check-up visit in the Primary Health Care Center in Podgorica, Montenegro, in a period from October 2012 to May 2016. Anthropometric measurements, biochemical parameters, and blood pressure were obtained. Multivariable logistic regression analysis was used to find the independent predictors for DM2 development in postmenopausal women. Results Age, waist circumference, and total bilirubin were the independent predictors for DM2 development in postmenopausal women (odds ratio [OR] =1.224, 95% confidence interval [CI] [1.117-1.341], P < 0.001; OR = 1.137, [95% CI = 1.036-1.215], P < 0.001, and OR = 0.727, [95% CI = 0.611-0.866], P < 0.001, respectively), whereas hsCRP lost its independent predictive role (OR = 1.155, [95% CI = 0.854-1.560], P = 0.349). Conclusion Unlike hsCRP, total bilirubin independently correlated with DM2 in postmenopausal women.

Comparison of Dako HercepTest and Ventana PATHWAY anti-HER2 (4B5) tests and their correlation with silver in situ hybridization in lung adenocarcinoma. Open Med (Wars) 2021; 16:1503-1512. [PMID: 34708154 PMCID: PMC8500854 DOI: 10.1515/med-2021-0366] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2021] [Revised: 08/13/2021] [Accepted: 09/14/2021] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Discordant results exist about the role of human epidermal growth factor receptor 2 (HER2) overexpression and/or HER2 amplification in lung adenocarcinoma. We aimed to compare the performance of HercepTest and PATHWAY anti-HER2 (4B5) by correlating immunohistochemistry (IHC) results with silver in situ hybridization (SISH) in adenocarcinoma lung specimens. METHODS A total of 148 surgically resected adenocarcinoma lung specimens were included. RESULTS HER2 overexpression was found in 7.4% patients for HercepTest Dako and in 2.7% patients for 4B5 antibody. The overall coincidence between these two types of antibodies equals 93.9%. The incidence of HER2 amplification in lung adenocarcinoma was 17.6%, of which in 2.7% of the cases high-grade amplification was present. HER2 amplification was present in 90.9% of patients with overexpression of HER2, obtained by using HercepTest Dako and 75% patients using 4B5 antibody. A significant correlation between overexpression of HER2 receptors obtained by HercepTest Dako and 4B5 antibody and HER2 amplification was shown. CONCLUSION The research of the efficiency of targeted molecular therapies with an HER2 antibody may serve as a basis for the introduction of routine HER2 status determination in lung adenocarcinoma, dictating the need for the standardized protocol for HER2 status determination in such pathology.

Low-grade chondrosarcoma of the larynx: A case report. World J Clin Cases 2021; 9:7805-7810. [PMID: 34621830 PMCID: PMC8462258 DOI: 10.12998/wjcc.v9.i26.7805] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 04/25/2021] [Accepted: 08/10/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Chondrosarcomas of the larynx are malignant tumours that most commonly originate from the hyaline cartilage. Chondrosarcoma of the larynx, the most common type of low-grade tumour, accounts for 1% of all laryngeal neoplasms.
CASE SUMMARY We present the case of a 60-year-old female patient who developed progressive hoarseness and shortness of breath over a 2-mo period. The patient had undergone resection of a laryngeal tumour 14 years before the aforementioned symptoms occurred, and histopathological analysis indicated that it was a chondroma. During the assessment of the patient, a submucosal, oval-shaped tumour was detected that was predominantly located on the left side of the larynx and was approximately 6 cm in size. The decision to perform left partial vertical laryngectomy was made. A pathohistological diagnosis of low-grade chondrosarcoma was made. Considering the results of pathohistological analysis and the positive margins of the resection, a total laryngectomy was performed. During the 12-mo follow-up, no local relapse or regional or distant metastases was detected.
CONCLUSION Chondrosarcoma of the larynx must be considered in the differential diagnosis of laryngeal submucosal tumours. It is crucial to carefully sample of tumour tissue, differentiate chondroma and chondrosarcoma, and consider the possibility of malignant changes from chondroma to chondrosarcoma.

Abstract
OBJECTIVE Coronary artery bypass grafting (CABG) seems to present a powerful trigger of oxidative stress (OS) and acute inflammatory response. This study aimed to estimate the effects of off-pump coronary artery bypass (OPCAB) grafting on the OS that is commonly observed in patients undergoing operation under cardiopulmonary bypass (CPB). Additionally, we aimed to examine the relationship between and paraoxonase 1 (PON1) activity and the degree of stenosis, severity and complexity of the atherosclerotic lesions, estimated by SYNTAX score (SS). PATIENTS AND METHODS Study group of 107 patients scheduled for CABG were divided into CPB and OPCAB group. Blood samples for OS markers measurement were collected at six-time intervals: before skin incision (t1), immediately after surgery (t2), 6h (t3), 24h (t4), 48h (t5) and 96h after cessation of the operation and surgical trauma (t6). SS was calculated. RESULTS A significant decrease in lipid hydroperoxides (LOOH) and advanced oxidation protein products (AOPP) levels after both types of surgeries were observed, whereas PON1 reduction was observed higher in the CPB than in the OPCAB group. A significant inverse correlation between SS values and PON1 activity, preoperatively and during the early postoperative hours after surgery [in t2, t3 time intervals (p<0.05 for all)] was found. ROC analysis showed that for CPB patients, Model with all OS parameters showed excellent accuracy (AUC=0.957, p<0.001) for prediction postoperative complications. CONCLUSIONS Decrease in PON1 activity during the early post-operative phases was related to higher SS. This relationship was more convincing in CPB, compared with OPCAB patients. Moreover, integrated models of OS status parameters have the capability to predict the development of postoperative complications.

Serum cystatin C levels are associated with triglycerides/high-density lipoprotein cholesterol ratio in adolescent girls ages between 16-19 years old. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2021; 24:10680-10686. [PMID: 33155226 DOI: 10.26355/eurrev_202010_23426] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Indexed: 11/12/2022]
Abstract
OBJECTIVE The pathophysiological role of cystatin C in cardiometabolic disorders is not completely explored in young population. On the other hand, together with the increase in obesity, dyslipidemia and insulin resistance (IR) are often observed even in youngsters. The aim of the study was to investigate the relationship between cystatin C and triglycerides-to-high-density lipoprotein cholesterol ratio (TG/HDL-c), as an indicator of dyslipidemia and a surrogate marker of IR in the cohort of adolescent girls ages between 16-19 years. PATIENTS AND METHODS A total of 99 girls were included in the study. Anthropometric and biochemical parameters were provided. Associations of biochemical markers with TG/HDL-c ratio were tested using univariable and multivariable ordinal regression analysis for TG/HDL-c ratio tertiles as dependent variable. RESULTS In univariate analysis, cystatin C levels were significantly associated with TG/HDL-c ratio (OR=1.813; 95% CI: 1.190-2.757, p=0.005). Furthermore, multivariate analysis revealed that cystatin C was an independent predictor of TG/HDL-c ratio when body mass index and high sensitivity C-reactive protein (i.e., markers that were significantly correlated with TG/HDL-c ratio in Spearman's correlation analysis) were included in the Model. Adjusted odds for cystatin C (OR=1.621; 95% CI: 1.028-2.552, p=0.037) demonstrated that rise in cystatin C by 0.1 mg/L increased the probability for higher TG/HDL-c tertile group by 1.621 times. CONCLUSIONS Serum cystatin C levels are associated with TG/HDL-c ratio in adolescent girls. Longitudinal studies are needed to confirm the causal relationship between cystatin C and TG/HDL-c ratio and to further explore its diagnostic and therapeutic potential in dyslipidemia and insulin resistance in young population.

Abstract
Background During embryonic development in women, a regression of temporary embryonic structures – mesonephric (Wolffian) ducts occurs. Adnexal tumors of Wolffian duct origin (FATWO) are rare. Case report We presented the case of a 64-year-old female patient who was diagnosed with FATWO. After the surgical treatment, the uterus with bilateral adnexal structures was submitted for histopathological analysis. The left ovary was occupied by a tumor measuring 80 × 60 × 50 mm, with smooth, shiny, whitish surface. Tumor cells were medium-sized, relatively uniform, round, and polygonal, with eosinophilic cytoplasm and centrally laid nucleus with fine chromatin, organized into solid, trabecular, and tubular formations. Tumor cells were positive for pancytokeratin (CK), CK7, CD10, neuron-specific enolase (NSE), synaptophysin, calretinin, progesterone, estrogen, and epithelial membrane antigen (EMA). Conclusion This case adds a report of a rare tumor to the literature. We must think of it in the differential diagnostic algorithm to make an accurate diagnosis for selecting the best treatment modality.

Data-Driven Cluster Analysis of Oxidative Stress Indexes in relation to Vitamin D Level, Age, and Metabolic Control in Patients with Type 2 Diabetes on Metformin Therapy. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:7942716. [PMID: 34239695 PMCID: PMC8241498 DOI: 10.1155/2021/7942716] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 06/05/2021] [Accepted: 06/12/2021] [Indexed: 11/17/2022]
Abstract
Recent advances in vitamin D research indicate that patients with type 2 diabetes mellitus (T2DM) are suffering from vitamin D deficiency and increased oxidative stress to a variable extent, which could produce different health impacts for each individual. The novel multivariate statistical method applied in the present study allows metabolic phenotyping of T2DM individuals based on vitamin D status, metabolic control, and oxidative stress status in order to identify effectively different subtypes in our type 2 DM study population. Data-driven statistical cluster analysis was performed with 95 patients with T2DM, treated with metformin. Clusters were based on 12 variables-age, disease duration, vitamin D level, insulin, fasting glycemia (FG), glycated hemoglobin (HbA1c), high-density and low-density lipoprotein, total cholesterol (TC), triglycerides (TG), body mass index (BMI), and triglycerides/glucose index (TYG). The analysis revealed four unique clusters which differed significantly in terms of vitamin D status, with a mean 25 (OH) D level in cluster 1 (57.84 ± 11.46 nmol/L) and cluster 4 (53.78 ± 22.36 nmol/L), falling within the insufficiency range. Cluster 2 had the highest mean level of 25 (OH) D (84.55 ± 22.66 nmol/L), indicative of vitamin D sufficiency. Cluster 3 had a mean vitamin D level below 50 nmol/L (49.27 ± 16.95), which is considered deficient. Patients in the vitamin D sufficient cluster had a significantly better glycemic and metabolic control as well as a lower level of lipid peroxidation compared to other clusters. The patients from the vitamin D sufficient cluster also had a significantly higher level of vitamin D/MPO, vitamin D/XO, vitamin D/MDA, vitamin D/CAT, and vitamin D/TRC than that in the vitamin deficient and insufficient clusters. The vitamin D deficient cluster included significantly younger patients and had a significantly lower level of AOPP/TRC and albumin/TRC than the vitamin D sufficient cluster. The evidence from our cluster analysis in the context of separated T2DM demonstrates beneficial effects of optimal vitamin D status on metabolic control and oxidative stress in T2DM patients. Older T2DM patients require higher vitamin D levels in order to achieve good metabolic control and favorable antioxidant protection. Since protein damage is more pronounced in these patients, adding water-soluble antioxidant in addition to higher doses of vitamin D should be considered.

Abstract
OBJECTIVE Considering the knowledge gap between underlying pathophysiological mechanisms of oxidative stress and increased cardiovascular risk, the present study aimed to examine the potential relationship between total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) and the Reynolds Risk Score (RRS) in the cohort of postmenopausal women. PATIENTS AND METHODS A total of 126 postmenopausal women participated in this cross-sectional study. Blood pressure, anthropometric and biochemical markers were determined. OSI was calculated as the TOS/TAS ratio. Associations of biochemical parameters with RRS were tested using univariable and multivariable logistic ordinal regression analysis. RESULTS TOS and OSI were the highest in women in high RRS category compared to moderate and low risk ones (p<0.001, for both). There was no difference in TAS level across RRS categories (p=0.370). Multivariable ordinal regression analysis showed independent association of TOS and OSI with RRS when tested with other clinical variables [OR=2.45; 95% CI (1.08-5.53); p=0.031 and OR=2.84; 95% CI (1.27-6.36); p=0.011, respectively]. CONCLUSIONS TOS and OSI are associated with the RRS in the cohort of postmenopausal women. Longitudinal studies are needed to confirm whether adding the TOS and OSI to the standard RRS algorithm could improve its potential to predict cardiovascular event.

Abstract
INTRODUCTION Markers of iron homeostasis are related to insulin resistance (IR) in adults. However, studies in children and adolescents are scarce and show contradictory results. The aim was to evaluate the potential relationship between iron status markers and IR. Additionally, no previous study has explored the mutual effect of biomarkers of iron homeostasis and inflammation (i.e. high sensitivity C-reactive protein (hsCRP)), and adipokines (i.e. retinol-binding protein 4 (RBP4)) on IR in the cohort of adolescent girls. MATERIAL AND METHODS A total of 60 girls age between 16 and 19 years were included in the study. Serum levels of ferritin, transferrin, soluble transferrin receptor (sTfR), hsCRP, and RBP4 were measured by immunonephelometry. Homeostasis model assessment of insulin resistance (HOMA-IR) and iron homeostasis indexes were calculated. Univariate and multivariate binary logistic regression analysis were used to investigate the possible independent associations of the examined biomarkers. Principal component analysis was used to examine their mutual effect on HOMA-IR in the studied girls. RESULTS Ferritin, sTfR, hsCRP and RBP4 were significant predictors for higher HOMA-IR in univariate analysis (p = 0.020, p = 0.009, p = 0.007, p = 0.003, respectively). Multivariate regression analysis after adjustment for waist circumference (WC) showed that serum sTfR levels remained positively associated with higher HOMA-IR (p = 0.044). Factorial analysis revealed that the obesity-inflammation related factor (i.e., WC and hsCRP) and adipokine-acute phase protein related factor (i.e., RBP4 and ferritin) showed significant differences between HOMA-IR < 2.5 and HOMA-IR ≥ 2.5. CONCLUSIONS Serum sTfR levels are independently associated with HOMA-IR, whereas higher serum ferritin levels together with higher RBP4 are related to higher HOMA-IR in adolescent girls.

Abstract
OBJECTIVE Determination of lipoprotein size and subclasses distribution can provide more significant information on cardiovascular disease risk than measurement of traditional lipid parameters alone. Accordingly, we aimed to examine their potential relationship with the novel biomarker of endothelial dysfunction, such as endocan in patients with type 2 diabetes mellitus (T2D), since there are no studies concerning this issue. PATIENTS AND METHODS This case-control study included a total of 42 individuals with T2D and 64 diabetes-free participants. Serum endocan, lipid parameters, and lipoprotein subclasses were measured. RESULTS Patients with T2D exhibited higher proportion of the smallest high-density lipoprotein (HDL) particles HDL 3c, as compared with diabetes-free participants (p=0.047). Higher serum endocan levels in T2D patients with low small dense low-density lipoprotein (LDL) particles (sdLDL) %, as compared with corresponding group of diabetes-free subjects was shown (p<0.01). Univariate binary logistic analysis revealed significant positive association of endocan and LDL diameter (OR=1.686, p=0.004), and negative associations of endocan with proportions of sdLDL (OR=0.928, p=0.007) and HDL3b (OR=0.789, p=0.009) particles. In a multivariate analysis, LDL diameter and proportions of sdLDL and HDL3b subclasses remained independent predictors of endocan levels in tested population. CONCLUSIONS The results of our study showed that larger LDL diameters, but lower sdLDL and HDL3b proportions were associated with higher endocan levels in population with T2D. More studies in the future are needed to confirm the observed relationship and to examine its causal nature.

Abstract
OBJECTIVE Hypertension is closely related to oxidative stress and inflammation. Endocan is a new inflammation marker whose role is not completely elucidated in hypertension. The aim of this study was to explore the association between endocan and several oxidative stress markers [i.e., advanced oxidation protein products (AOPP), total protein sulfhydryl (SH-) groups and prooxidant-antioxidant balance (PAB)] in adult population with hypertension. PATIENTS AND METHODS A total of 90 patients with hypertension were compared with 44 controls. Blood pressure, anthropometric and biochemical parameters were measured. Associations of clinical data with hypertension were tested with univariable and multivariable logistic ordinal regression analysis. RESULTS Endocan and AOPP were significantly higher in hypertensive patients than in the controls (p=0.006 and p=0.046, respectively). In the multivariable logistic regression analysis, AOPP and endocan kept their independent positive associations with hypertension. As AOPP rose by 1 μmol/L and endocan rose by 1 pg/mL, the probability for hypertension presence rose by 4.2% and 32.2%, respectively and 39.9% of variation in hypertension could be explained with the Model. The area under the Receiver Operating Characteristic curve [(AUC) for AOPP=0.638 (0.550-0.719), p=0.01 and for endocan=0.679 (0.593-0.757), p<0.001] demonstrated sufficient clinical accuracy towards hypertension. On the contrary, the Model showed very good clinical accuracy [AUC= 0.825 (0.749-0.900), p<0.001]. CONCLUSIONS Endocan and AOPP are independently correlated with hypertension in adult population and these tested markers together could be reliable parameters to discriminate patients with hypertension from normotensive ones.

The Effects of Vitamin D Supplementation on Metabolic and Oxidative Stress Markers in Patients With Type 2 Diabetes: A 6-Month Follow Up Randomized Controlled Study. Front Endocrinol (Lausanne) 2021; 12:610893.

Abstract
Vitamin D deficiency could play an important role in the pathogenesis of type 2 diabetes mellitus (T2DM) as it may alter several crucial processes in the development of diabetes and its complications, such as pancreatic insulin secretion, peripheral insulin resistance, persistence of systemic "sterile" inflammation and immune activation. Vitamin D may also have an antioxidant effect through the inhibition of free radicals generation. The reported study was designed with eligible consecutively recruited patients with T2DM on standard metformin therapy (n=130), randomized in 1:1 ratio, considered to have undergone Vitamin D supplementation according to the guidelines proposed by the Endocrine Society, or to have continued with metformin only. The potential benefit was monitored through the influence on glycemia level, glycated haemoglobin (HbA1c), insulin resistance index (calculated as homeostatic model assessment; HOMA-IR), Castelli Risk Index I and Tryglicerides/Thiobarbituric acid-reactive substances (TG/TBARS) Index in a 6-month follow up period. Our study indicates that oral daily doses of vitamin D improve HbA1c levels over the 3-month and 6-month period, followed by a significant decrease in advanced oxidation protein products levels over the 3-month period when higher vitamin D doses are given. The effect of vitamin D on HOMA-IR index, malondialdehyde levels and TG/TBARS index was not statistically significant. Further investigation should consider defining the doses of vitamin D in patients with T2DM which may attenuate the oxidative stress risk, the risk of metabolic syndrome and the risk of related cardiovascular events.

Abstract
INTRODUCTION The performed study focused on determining the effect of vitamin D supplementation on enzymes involved in both inflammation and reactive oxygen species (ROS) production and ROS degradation in patients with type 2 diabetes mellitus (T2DM). MATERIAL AND METHODS The 6-month follow-up, randomized, controlled study included 140 patients with T2DM, ≥ 30 years old, with good metabolic control, treated with metformin and lifestyle advice only. All patients were randomly assigned to two groups (70 each). Patients from the first group (Intervention group) were assigned to receive vitamin D3 50 000 IU or 14 000 IU regarding their vitamin D baseline levels. Patients from the second (Metformin) group continued to receive only metformin during the 6-month study period. RESULTS After 6 months, the myeloperoxidase activity was significantly lower and gradually decreased in the Intervention group by about 40%, compared to the baseline measurement (p = 0.015) and compared to the Metformin group (p = 0.001). After 6 months, the xanthine oxidase (XO) activity decreased significantly in the Intervention group compared to the baseline and 3rd month levels (p < 0.001). In the Metformin group there was also a significant decrease in XO after 6 months compared to baseline (p < 0.001) and the 3rd month (p = 0.003). The catalase activity significantly increased within the Intervention group only when comparing the 3rd and 6th month (p = 0.027). CONCLUSIONS Our study showed that vitamin D may improve endothelial dysfunction in patients with T2DM on metformin therapy by influencing two important factors implicated in the pathogenesis of diabetic complications - ROS production and inflammation, which can additionally contribute to a stable metabolic control during metformin therapy.

Abstract
INTRODUCTION We aimed to examine serum endocan level and the summary involvement of dyslipidemia, oxidative stress (OS) and inflammation by calculation of its comprehensive score (i.e. Dyslipidemia-Oxy-Inflammation (DOI) score) in relation to glucoregulation in subjects with prediabetes and overt type 2 diabetes (T2D). MATERIAL AND METHODS A total of 59 patients with prediabetes and 102 patients with T2D were compared with 117 diabetes-free controls. Glycated hemoglobin (HbA1c), inflammation, OS and lipid parameters were measured. Associations of clinical data with HbA1c level were tested with univariate and multivariate logistic ordinal regression analysis. HbA1c as a dependent variable is given at the ordinal level (i.e. < 5.7%; 5.7-6.4%, > 6.4%, respectively). RESULTS Endocan was significantly higher in the T2D group than in the controls. As endocan concentration rose by 1 unit, the probability for higher HbA1c concentration increased by more than 3 times (OR = 3.69, 95% CI: 1.84-7.01, p < 0.001). Also, a rise in the dyslipidemia score, oxy score, inflammation score and DOI score by 1 unit increased the probability of higher HbA1c concentration by 19%, 13%, 51% and 11%, respectively. In the models, after adjustment for confounding variables, endocan and DOI score remained independent predictors of HbA1c level. CONCLUSIONS Endocan and DOI score are independently correlated with HbA1c in patients with prediabetes and overt T2D.

Cardiovascular Risk Estimated by UKPDS Risk Engine Algorithm in Diabetes. Open Med (Wars) 2019; 13:610-617. [PMID: 30847393 PMCID: PMC6400147 DOI: 10.1515/med-2018-0086] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2018] [Accepted: 10/31/2018] [Indexed: 12/19/2022] Open
Abstract
Since there is a high prevalence of type 2 diabetes mellitus (DM2), as well as CVD in Montenegro, we aimed to estimate CVD risk by United Kingdom Prospective Diabetes Study (UKPDS) risk engine algorithm in individuals with DM2. Furthermore, we aimed to explore whether non-traditional biomarker such as high sensitivity C-reactive protein (hsCRP) is superior for CVD risk prediction over old traditional risk factors. A total of 180 participants with DM2 (of them 50% females) were included in the current cross-sectional study. Biochemical and anthropometric parameters, and blood pressure were obtained. More males than females were classified at high UKPDS risk category (p<0.001). Also, about one third of diabetic patients (29.4%) were classified into the high-risk category. In multivariate regression analysis, triglycerides [Odds ratio (OR) =1.703, p=0.001] and creatinine concentration (OR=1.040, p<0.001) were independent predictors of CVD risk, whereas hsCRP was not correlated with CVD risk. HsCRP is not superior for CVD risk prediction by UKPDS risk engine algorithm over high triglyceride and creatinine levels in diabetic population, which suggests that the old traditional markers must not be underestimated when examining CVD risk in population with diabetes.

Abstract
Abstract
Background
Retinol-binding protein 4 (RBP4) and cystatin C are regarded as novel metabolic risk markers. Therefore, we aimed to examine which one of these biomarkers better correlates with metabolic syndrome (MetS) in a cohort of postmenopausal women.
Methods
A total of 129 postmenopausal women (among which 62 women had MetS) were recruited in this cross-sectional study. MetS was diagnosed according to the International Diabetes Federation criteria.
Results
Cystatin C and RBP4 levels were significantly higher in women with MetS, compared to those without MetS (p=0.011 vs. p<0.001, respectively). A significant difference in the proportion of women with and without MetS across cystatin C and RBP4 quartiles was observed (χ2=5.1, p=0.025, and χ2=11.1, p=0.001, respectively). Logistic regression analysis revealed a borderline significant relationship between cystatin C and MetS (p=0.066), but this significance disappeared after adjustment for age, inflammation level and duration of menopause (p=0.221). On the contrary, a significant relationship between RBP4 and MetS was observed not only without adjustment (p=0.009), but also even after adjustment for age, inflammation level and duration of menopause (p=0.006).
Conclusions
RBP4 better correlates with MetS than cystatin C in postmenopausal women.

Older age and HDL-cholesterol as independent predictors of liver fibrosis assessed by BARD score. Minerva Med 2019; 110:191-198.

Abstract
BACKGROUND It is known that non-alcoholic fatty liver disease (NAFLD), and in particular non-alcoholic steatohepatitis, can progress to advanced fibrosis. However, pathophysiological mechanisms implicated in this evolution are not elucidated yet. We aimed to investigate the independent predictors of liver fibrosis in patients with NAFLD, determined by BARD score, one of the most used algorithms for fibrosis evaluation. METHODS This prospective study enrolled a total of 301 participants with NAFLD, as determined by a Fatty Liver Index (FLI) ≥60. All patients were categorized into two groups: with no/mild fibrosis (BARD score 1, N.=62) and with advanced fibrosis (BARD score 2, 3 and 4 N.=239). RESULTS Serum high density lipoprotein cholesterol (HDL-c), glucose and glycated hemoglobin were higher (P=0.028, P<0.001 and P=0.002, respectively), whereas serum transaminases and gamma glutamil transferase levels were lower in patients with advanced fibrosis than in those with no/mild fibrosis (P=0.010, P<0.001 and P=0.005, respectively). There were no significant differences in oxidative stress (i.e., advanced oxidant protein products and malondialdehyde) and anti-oxidative protection markers (i.e., catalase) between patients with no/mild fibrosis and advanced fibrosis. Multivariate ordinal regression analysis showed independent associations and predictions of ages (OR=1.071, 95% CI 1.004-1.097, P<0.001), and HDL-c levels (OR=2.549, 95% CI 1.087-5.989, P=0.032) on BARD score categories in patients with NAFLD. CONCLUSIONS In conclusion, we found that older age and higher HDL-c, are independent predictors for advanced liver fibrosis assessed with the BARD score. Future investigations are needed to further explore this relationship.

Sodium and Potassium Intake, Knowledge Attitudes and Behaviour Towards Salt Consumption Amongst Adults in Podgorica, Montenegro. Nutrients 2019; 11:nu11010160. [PMID: 30642124 PMCID: PMC6356471 DOI: 10.3390/nu11010160] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2018] [Revised: 12/14/2018] [Accepted: 01/08/2019] [Indexed: 12/15/2022] Open
Abstract
Excess salt and inadequate potassium intakes are associated with high cardiovascular disease (CVD). In Montenegro, CVD is the leading cause of death and disability. There is no survey that has directly measured salt and potassium consumption in Montenegro. The aim is to estimate population salt and potassium intakes and explore knowledge, attitudes and behaviour (KAB), amongst the adult population of Podgorica. Random samples of adults were obtained from primary care centres. Participants attended a screening including demographic, anthropometric and physical measurements. Dietary salt and potassium intakes were assessed by 24 h urinary sodium (UNa) and potassium (UK) excretions. Creatinine was measured. KAB was collected by questionnaire. Six hundred and thirty-nine (285 men, 25–65 years) were included in the analysis (response rate 63%). Mean UNa was 186.5 (SD 90.3) mmoL/day, equivalent to 11.6 g of salt/day and potassium excretion 62.5 (26.2) mmoL/day, equivalent to 3.2 g/day. Only 7% of them had a salt intake below the World Health Organization (WHO) recommended target of 5 g/day and 13% ate enough potassium (>90 mmoL/day). The majority (86%) knew that high salt causes ill-health. However, only 44% thought it would be useful to reduce consumption. Salt consumption is high and potassium consumption is low, in men and women living in Podgorica.
