RESUMEN
BACKGROUND: Psoriasis is a chronic inflammatory disease that is associated with many inflammatory conditions such as atherosclerosis, hypertension, among others. SCUBE-1 is a protein that plays a role in angiogenesis. OBJECTIVES: The present study aimed to investigate whether SCUBE-1 could indicate subclinical atherosclerosis in psoriatic patients, and to compare SCUBE-1 levels, measurement of carotid artery intima-media thickness (CIMT), and metabolic parameters in psoriasis patients and healthy controls. METHODS: Forty-six patients with psoriasis and 43 healthy controls were included. The severity of the disease was assessed with Psoriasis Area Severity Index (PASI) in the patient group. Levels of SCUBE-1, CRP, lipids, and fasting glucose were measured with the enzyme-linked immunosorbent assay (ELISA) method, and CIMT measurements were performed by the same cardiologist. RESULTS: SCUBE-1 levels and CIMT values were significantly higher in the patient group (for both p < 0.05). Moreover, systolic blood pressure, CRP levels, and waist circumference were higher in the patient group even though both groups had similar BMIs (for all p < 0.05). A positive correlation was found between SCUBE-1 and CIMT values among patients, and multiple regression analyses revealed that SCUBE-1 and CIMT are significantly associated with psoriasis as well. STUDY LIMITATIONS: A low number of participants and not including any other inflammatory marker related to angiogenesis or atherosclerosis such as VEGF, adiponectin are the main limitations of the present study. CONCLUSION: Despite the severity of the disease, even in psoriasis patients with mild disease the SCUBE-1 level may be an indicator of subclinical atherosclerosis and indicate the risk of cardiovascular disease in the future.

OBJECTIVE: MicroRNAs have been explored as potential biomarkers for many pathological processes including coronary artery disease. In this study, we aimed to compare the circulating levels of selected atherosclerosis-associated miRNAs in patients with a history of early-onset coronary artery disease with that of age- and sex-matched healthy controls and older patients with late-onset coronary artery disease. METHODS: Study population consisted of 30 patients with early onset coronary artery disease, 31 age- and sex-matched healthy controls, and 30 patients with late-onset coronary artery disease. Plasma levels of 13 microRNAs (endothelial cell-related miR-126, -92a/b; vascular smooth muscle cell-related miR-145; inflammation-related miR-16, -21, -125b, -146a/b, -147b, -150, -155; lipometabolism-related miR-27b, -122, -370) were evaluated by using real-time polymerase chain reaction. RESULTS: In patients with early onset coronary artery disease, plasma expressions of the lipometabolism-related miR-27b, miR-122; inflammation-related miR-125b, miR-146a/b, miR-147b, miR-150, miR-155; and VSMC-related miR-145 were significantly downregulated and endothelial cell-related miR-126 was significantly upregulated compared to age- and sexmatched healthy controls. Circulating microRNA profile of patients with early onset coronary artery disease was also different from that of older patients with late-onset coronary artery disease. Plasma levels of miR-21, miR-27b, miR-122, miR-125b, miR-146b, miR-147b, and miR-155 were lower and plasma levels of miR-16 and miR-92a were higher in patients with early onset coronary artery disease compared to older patients with late-onset coronary artery disease. CONCLUSION: MicroRNAs are promising biomarkers for early onset coronary artery disease.

PURPOSE: The aim of this study was to investigate the possible role of raftlin (RFTN) in chronic rhinosinusitis with nasal polyps (CRSwNP). There is no study in the literature investigating the role of RFTN in the pathogenesis of CRSwNP. METHODS: The present study was designed as a case-control study and conducted between 25.09.2020 and 01.01.2022. CRSwNP and control groups were formed in the study. Serum and tissue samples were taken from each patient in the study and their RFTN levels were measured. While nasal polyps were used for tissue samples in the CRSwNP group, middle meatus mucosa obtained during concha bullosa surgery was used in the control group. RESULTS: The control group included 31 patients (8 female, 23 male) and the CRSwNP group included 49 patients (14 female, 35 male). The mean age of the control group was 40.42 ± 9.99 years, while the mean age of the CRSwNP group was 43.47 ± 10.19 years. When the groups are compared in terms of gender and age, there were no statistically significant differences (p = 0.78, p = 0.19, respectively). The serum RFTN levels in the control and CRSwNP groups were 7.85 ± 10.87 ng/ml, and 7.02 ± 8.59 ng/ml, respectively (p = 0.45). The tissue RFTN levels in the control group and CRSwNP group were 87.15 ± 69.91 ng/ml, and 66.50 ± 17.10 ng/ml, respectively (p = 0.04, statistically significant). CONCLUSION: RFTN deficiency in nasal polyp tissue may be one of the reasons for the development of CRSwNP. Further studies are needed to elucidate the role of RFTN in CRSwNP.

INTRODUCTION: Recent data have shown that diabetic kidney disease (DKD) is associated with abnormal gut microbiota composition. Zonulin is a physiological tight junction modulator and an intestinal permeability marker. In this study we aimed to investigate serum levels of zonulin and interleukin 6 (IL-6) in patients with type 2 diabetes mellitus (T2DM) and different levels of albuminuria. MATERIAL AND METHODS: Ninety patients with T2DM and 30 healthy controls (HC) aged between 18 and 65 years were enrolled in the study. T2DM patients were divided into three groups as patients with normoalbuminuria (n = 30), microalbuminuria (n = 30), and macroalbuminuria (n = 30). Serum zonulin and IL-6 levels were measured by ELISA method. RESULTS: There was no significant difference between groups in terms of age, gender, serum ALT, LDL-C, HDL-C, and zonulin levels (p > 0.05). Significant differences between groups were present for the duration of diabetes (p < 0.001), body mass index (p < 0.001), fasting blood glucose (p < 0.001), creatinine (p < 0.001), uric acid (p = 0.037), triglyceride (p = 0.003), total cholesterol (p < 0.001), glycated haemoglobin (p < 0.001), and IL-6 (p < 0.001) levels. IL-6 levels were significantly increased in the microalbuminuria and macroalbuminuria groups compared to the HC group, but no significant difference was determined between the HC and normoalbuminuria group. In patients with diabetic kidney disease, a significant positive correlation was found between zonulin with IL-6 and proteinuria (rho = 0.296, p = 0.008; rho = 0.190, p < 0.047, respectively). The serum IL-6 level was positively correlated with microalbuminuria and proteinuria (rho = 0.451, p < 0.001; rho = 0.425, p < 0.001, respectively). CONCLUSIONS: We suggest that the serum zonulin level is not a promising biomarker to assess the severity of DKD in patients with long-standing T2DM.

The aim of this study was to determine whether serum VEGF, IGF-1, and HIF-1α levels differed between Autism Spectrum Disorder (ASD) patients and healthy controls. A total of 40 children with ASD and 40 healthy controls aged 4-12 years were included. Serum levels of VEGF, IGF-1, and HIF-1α were measured using commercial enzyme-linked immunosorbent assay kits. Serum IGF-1 levels were found to be statistically significantly higher in the ASD group than in the control group. Serum HIF-1α levels were borderline significantly lower in the ASD group. There was no statistically significant difference in serum VEGF levels between the two groups. IGF-1 and HIF-1α may play a potential role in the etiopathogenesis of ASD.

PURPOSE: To evaluate the serum level of zonulin, which is an intestinal permeability (IP) biomarker, in primary hyperparathyroidism (PHPT) and to investigate the relationship between zonulin, calcium, and parathormone (PTH) levels. METHODS: The study included 34 healthy control (HC) and 39 patients with PHPT. Serum calcium, phosphorus, magnesium, creatinine, albumin, and 24 h urine calcium levels were measured in all groups. Serum levels of zonulin were measured quantitatively by enzyme-linked immunosorbent assay (ELISA). Urinary ultrasonography (to assess the presence of nephrolithiasis) and dual energy X-ray absorptiometry (to assess the presence of osteoporosis) were used to evaluate complications related to PTHP. RESULTS: Serum zonulin levels were significantly higher in the PHPT group than the HC group (p < 0.001). Zonulin levels were significantly positively correlated with plasma PTH and serum calcium levels (r = 0.600, p < 0.001 and r = 0.610, p < 0.001; respectively). There was no correlation between serum zonulin levels and adenoma volume. CONCLUSION: Serum zonulin level increases in patients with PHPT. Serum zonulin levels show a moderate/strong positive correlation with serum calcium and plasma PTH levels. This suggests that IP increase may play a role in the development of hypercalcemia in patients with PHPT.

INTRODUCTION: Bronchiectasis (B), commonly seen in patients with chronic obstructive pulmonary disease (COPD), is associated with exacerbations and predicts mortality. OBJECTIVES: To differentiate patient groups with COPD-(B+) or COPD-(B-) and their exacerbations by using inflammatory markers. METHODS: Consecutive COPD patients were divided into two groups according to findings on high resolution thorax CT (HRCT) images using Smith and modified Reiff scores. Patients were prospectively followed for possible future exacerbations. Serum fibrinogen, C-reactive protein (CRP), soluble urokinase-type plasminogen activator receptor (suPAR) and Plasminogen activator inhibitor-1 (PAI-1) levels were studied during exacerbation and stable periods. RESULTS: Eighty-seven patients were included and (85 M, 2 F), mean aged was 68.1 ± 9 (46-87). HRCT confirmed bronchiectasis in 38 (43.7%) patients, most commonly in tubular form (89.4%) and in lower lobes. COPD-B(+) group had lower body mass index (P = 0.036), more advanced stage of disease (P = 0.004) and more frequent exacerbation (P = 0.01). The HRCT scores were correlated with exacerbation rate (r = 0.356, P < 0.05). Fibrinogen and CRP values were higher in exacerbation (P = 0.01, P = 0.013, respectively) especially in COPD-B(+) patients. suPAR and PAI-1 levels were also higher in COPD-B(+) patients although it was not statistically significant. CONCLUSION: Bronchiectasis is common and causes frequent exacerbations in COPD. Identifying of COPD-B(+) phenotype by HRCT scoring systems has considerable importance for both therapeutic options and clinical outcome of the disease. In addition to fibrinogen and CRP, high serum levels of suPAR and PAI-1 suggest us their significant roles in increased systemic inflammation associated with coexisting of COPD and bronchiectasis.

PURPOSE: The purpose of this study was to investigate the clinical use of copeptin to evaluate migraine attacks in the Emergency Department. An additional aim was to detect changes in serum copeptin levels in migraine patients during attack and attack-free periods. METHODS: This prospective case-control study included 52 migraine patients and 51 healthy individuals with similar demographic characteristics. Blood samples were collected from migraine patients both in attack and attack-free periods. RESULTS: The mean copeptin levels in the patients group in the attack and attack-free periods were 689.28 and 576.68â¯pg/ml, respectively, whereas they were 608.68â¯pg/ml in the control group. There was a significant difference in the mean copeptin level in the attack period and attack-free periods (pâ¯=â¯0.026). The sensitivity and specificity of copeptin in detecting headache episodes in migraine patients were 58.8% and 60.7%, respectively, at a cut-off value of 388.67â¯pg/ml. CONCLUSION: This is the first study to investigate the diagnostic efficacy of serum copeptin levels in migraine patients. Although the diagnostic efficacy of serum copeptin levels for migraines was unsatisfactory, it could be helpful at management of migraine patients in ED.

Background/aim: Verruca vulgaris is a benign disease characterized with papillomas on the skin and mucosa. The aim of this study was to investigate the serum levels of coenzyme Q10, MDA, and zinc as well as the lipid profile of verruca vulgaris patients and examine the relationship between these parameters and clinical manifestations of the disease. Materials and methods: The study included 49 verruca vulgaris patients (mean age: 32.01 ± 14.20 years; 22 males, 27 females) and 40 healthy volunteers (mean age: 31.63 ± 8.98 years; 21 males and 19 females). Coenzyme Q10 levels were assessed by using an enzyme- linked immunosorbent assay. Serum MDA levels were measured spectrophotometrically. Zinc levels were measured using a Perkin Elmer AAnalyst 800 atomic absorption spectrometer with a deuterium background correction and additional standard techniques. Results: The coenzyme Q10 levels were found to be higher in the verruca vulgaris group compared to the healthy volunteers. However, this increase was not statistically significant (P = 0.195). Zinc levels were significantly lower in the verruca vulgaris group compared to the healthy volunteers (P = 0.002). In the patient group, MDA levels and HDL levels were significantly higher compared to the healthy volunteers (P = 0.023 and P = 0.004, respectively). Additionally, there was no statistically significant difference between the groups in the CoQ10/Total cholesterol ratio (P = 0.433). Conclusion: Reduced serum zinc levels and increase of oxidative stress in verruca vulgaris may be a factor responsible for development of verruca vulgaris.

Background/aim: IL-23R gene polymorphisms and the association of these polymorphisms with serum IL-23 levels were investigated in patients with psoriasis in the current study. Materials and methods: Sixty-seven patients with psoriasis who were admitted to our dermatology outpatient clinic and 67 healthy controls were included in the study. Polymorphisms of the IL-23R gene were determined by KASP-PCR method, and serum IL-23 levels were determined by ELISA method. Results: The distribution of IL-23R gene polymorphisms rs2201841, rs11209026, rs7530511, rs1343152, and rs11465804 was not significantly different in the patient and control groups. The AA genotype of the rs2201841 locus in males and the GA genotype in females, as well as the AA genotype of the rs1343152 locus in males and the CA genotype in females, were statistically significant in patients with psoriasis. The mean serum IL-23 level was significantly lower in the patient group (42.62 ± 5.96) compared to the control groups (75.76 ± 13.24). Conclusion: IL-23R gene polymorphisms including rs2201841, rs11209026, rs7530511, rs11465804, and rs1343152 were not found to be significantly related to psoriasis. Different genetic polymorphisms may play a role in the development of psoriasis in female and male populations. Ethnic differences between different populations may have led to differences in the distribution of polymorphisms in the current study with compared to other published studies. Additionally, many different genes, polymorphisms, and environmental factors that have an effect on the development of psoriasis may affect the disease process.

INTRODUCTION: The detection of HCV-RNA by PCR assays is considered to be the gold standard for confirming the presence of HCV viremia. However, high costs, long and laborious procedures limit their widespread usage. This retrospective study was conducted to assess the predictive performances of biochemical and hematological parameters, anti-HCV signal-to-cutoff (S/CO) ratios and RIBA assay for HCV viremia. METHODOLOGY: Medical records of 210 patients with positive anti-HCV results were analyzed. Samples were tested for anti-HCV by the Roche Elecsys assay. RIBA and PCR assays were performed with Inno-Lia HCV Score test, and Roche Cobas TaqMan HCV test, respectively. RESULTS: Anti-HCV positive patients were categorized into two groups: positive HCV-RNA(viremic) group (n = 94) and negative HCV-RNA(non-viremic) group (n = 116). All viremic patients had positive RIBA results, while in the non-viremic group, 80 (69%) patients had negative/indeterminate RIBA results and 36 (31%) patients had positive RIBA results. Compared with the non-viremic group, the viremic group had significantly higher alanine aminotransaminase (ALT), aspartate aminotransferase, gamma-glutamyl transferase, mean platelet volume, platelet distribution width and anti-HCV levels, and significantly lower platelet count and plateletcrit levels (p < 0.05). With multivariate logistic regression analysis, serum ALT and anti-HCV levels were found to be strong predictive factors for HCV viremia. A S/CO ratio of ≥ 12.34 was identified as the optimal anti-HCV level to predict viremia. CONCLUSIONS: An anti-HCV S/CO ratio of 12.34 can determine the necessity for PCR assay, when carefully evaluated together with the biochemical and hematological evidence. This approach may reduce the cost of diagnosis particularly in low-resource settings.

Long-term exposure to organophosphate pesticides (OPs) without acute poisoning can lead to various OPs. Environmental exposure to organophosphate pesticides may be associated with depression and suicide attempts in a population living in a rural agricultural area. Patients (n = 149) suffering from major depressive disorder (with and without attempted suicide) and a control group of healthy individuals (n = 64) who had been living in the same rural district for at least 1 year were selected. Red blood cell acetylcholine esterase (RBC-AChE) activity was examined as the basis of evaluating the degree of chronic environmental exposure to OPs residues. There were negative association between RBC-AChE activity levels and suicide attempts, the number of past suicide attempts and hopelessness levels in the depressive patients. The results of the study may support the idea that environmental exposure to OPs may be associated with mental health in individuals living in agricultural districts who are not farmers or working in occupations with access to OPs.
RESUMEN
BACKGROUND/AIM: F2α-isoprostane is accepted as an oxidative stress indicator and melatonin shows neuroprotective effects by antioxidative and antiamyloidogenic influences. By measuring these in patients diagnosed with minimal cognitive impairment (MCI) and Alzheimer-type dementia, we intended to demonstrate whether the measurement of these markers contributes to early diagnosis of Alzheimer disease (AD) in the MCI stage or not. MATERIALS AND METHODS: Three groups (n = 63) were created: the AD group, MCI group, and control group. Serum melatonin levels were measured by radioimmunoassay method, and plasma total 8-isoPGF2α levels were measured by enzyme immunoassay method. RESULTS: Significant differences were observed in the melatonin levels between the MCI group and AD group (P = 0.009), and in 8-isoPGF2α levels between the AD group and control group (P = 0.022). A negative correlation between mini-mental state examination (MMSE) scores and 8-isoPGF2a levels (r = -0.459, P < 0.001) and positive correlation between MMSE scores and melatonin levels (r = 0.317, P = 0.011) were found. CONCLUSION: Although the plasma 8-isoPGF2α and serum melatonin levels in MCI were not found to be good early diagnostic markers to indicate risk of AD, results were found to support the role of oxidative stress in AD.
