Serum S100B level increases after running but not cycling exercise

The objective of this study was to investigate the effect of running versus cycling exercises upon serum S100B levels and typical markers of skeletal muscle damage such as creatine kinase (CK), aspartate aminotransferase (AST) and myoglobin (Mb). Although recent work demonstrates that S100B is highly expressed and exerts functional properties in skeletal muscle, there is no previous study that tries to establish a relationship between muscle damage and serum S100B levels after exercise. We conducted a cross-sectional study on 13 male triathletes. They completed 2 submaximal exercise protocols at anaerobic threshold intensity. Running was performed on a treadmill with no inclination (RUN) and cycling (CYC) using a cycle-simulator. Three blood samples were taken before (PRE), immediately after (POST) and 1 h after exercise for CK, AST, Mb and S100B assessments. We found a significant increase in serum S100B levels and muscle damage markers in RUN POST compared with RUN PRE. Comparing groups, POST S100B, CK, AST and Mb serum levels were higher in RUN than CYC. Only in RUN, the area under the curve (AUC) of serum S100B is positively correlated with AUC of CK and Mb. Therefore, immediately after an intense exercise such as running, but not cycling, serum levels of S100B protein increase in parallel with levels of CK, AST and Mb. Additionally, the positive correlation between S100B and CK and Mb points to S100B as an acute biomarker of muscle damage after running exercise.

β-human chorionic gonadotropin (HCG) level is not a reliable marker for early identification of persistent gestational trophoblastic neoplasia (GTN) after evacuation of hydatidiform mole. Thus, this study was conducted to evaluate β-HCG regression after evacuation as a predictive factor of malignant GTN in complete molar pregnancy. Methods. In this cross-sectional study, we evaluated a total of 260 patients with complete molar pregnancy. Sixteen of the 260 patients were excluded. Serum levels of HCG were measured in all patients before treatment and after evacuation. HCG level was measured weekly until it reached a level lower than 5 mIU/mL. Results. The only predictors of persistent GTN are HCG levels one and two weeks after evacuation. The cut-off point for the preevacuation HCG level was 6000 mIU/mL (area under the curve, AUC, 0.58; sensitivity, 38.53%; specificity, 77.4%), whereas cut-off points for HCG levels one and two weeks after evacuation were 6288 mIU/mL (AUC, 0.63; sensitivity, 50.46%; specificity, 77.0%) and 801 mIU/mL (AUC, 0.80; sensitivity, 79.82%; specificity, 71.64%), respectively. Conclusion. The rate of decrease of HCG level at two weeks after surgical evacuation is the most reliable and strongest predictive factor for the progression of molar pregnancies to persistent GTN.

Background: Febrile neutropenia is still one of the most important complications of treatment in cancer patients. These patients become prone to infection and consequently higher mortality and morbidity. This study aimed to determine the accuracy of serum procalcitonin (PCT) level in the detection of infection in pediatric cancer patients complicated with febrile neutropenia. Materials and Methods: In this cross-sectional study, all pediatric patients affected by cancer and febrile neutropenia following chemotherapy (n=107) were investigated from August 2014 to August 2015. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum levels of PCT, as well as blood and urine culture, were evaluated in all patients. Results: The mean age of the patients was 78 ± 55 months (3 - 214 months), and in terms of gender, 53 patients (49.5%) were male. Overall, 25 patients (23.4%) and 13 patients (12%) showed positive blood and urine culture, respectively. The area under the curve (AUC) receiver operating characteristic (ROC) curve was illustrated to determine how much PCT can couldpredict infection.(AUC =0.74, 95% CI: 0.61-0.87, P<0.001). Considering the cut-off of serum PCT levels as 0.70ng/mL, sensitivity, specificity, and positive and negative predictive valueof PCT were 0.76, 0.744, 0.475, and 0.91, respectively. In addition, PCT showed significant correlations with CRP (rs=0.415, P<0.001) and ESR (rs =0.262, P=0.009). Conclusion: According to the findings of this study, serum PCT levels can be used as a diagnostic test with acceptable sensitivity and specificity and high negative predictive value, but the low positive predictive value in the evaluation of infections in patients affected by cancer and complicated with fever and neutropenia.

Background Granulomatosis with polyangiitis (GPA) is a representative of vasculitides associated with anti-neutrophil cytoplasmic autoantibodies. “Classical” antibodies directed against proteinase 3 are involved in the pathogenesis and are part of the GPA diagnosis at the same time. Along with them, however, antibodies against Lysosomal-Associated Membrane Protein-2 (LAMP-2) and antibodies directed against plasminogen have been described in GPA. Objectives and methodology: We performed a cross-sectional study enrolling 34 patients diagnosed with GPA. Our study was aimed at looking for correlations between serum levels of LAMP-2 and plasminogen and the clinical manifestations of the GPA. Furthermore, we examined serum levels of tumor necrosis factor-alpha (TNF-α) and its associated indoleamine-pyrrole 2,3-dioxygenase (IDO), as well as we looked for a correlation between these cytokines and the clinical manifestations of GPA. Results The results showed that in GPA, serum plasminogen levels were negatively associated with renal involvement (receiver operating characteristic (ROC) area under the curve (AUC) of 0.78) (95% CI 0.53–0.91), p = 0.035, and the extent of proteinuria, Spearman’s Rho = –0.4, p = 0.015. Increased levels of TNF-α and IDO correlated with disease activity, Spearman’s Rho =0.62, p = 0.001 and Spearman’s Rho = 0.4, p = 0.022, respectively, whereas only TNF-α was increased in severe forms of GPA with lung involvement (ROC AUC of 0.8) (95% CI 0.66–0.94), p = 0.005. Conclusions In this study, we demonstrate the alteration of soluble factors, which play an important role in the pathogenesis of GPA and their relationship with the clinical manifestations of the disease. Our main results confirm the associations of increased secretory TNF-α and some clinical manifestations, and we describe for the first time decreased serum plasminogen levels and their association with renal involvement.

Abstract Objective To evaluate serum levels of adiponectin in pregnant adolescents between 30 and 36 weeks of gestation. Method: A prospective cross-sectional study enrolled 67 normal pregnant women between 30 and 36 weeks of gestation and eutrophic (body mass index [BMI]: 18.5–25 kg/m2), of which 36 were adolescents (< 20 years old) and 31 adults (≥ 20 years old). Serum adiponectin levels were determined by enzyme-linked immunosorbent assay (ELISA). The t-student or Mann-Whitney tests were used for intergroup comparison. Results Pregnant adolescents showed significantly higher serum adiponectin concentrations compared with pregnant adults (p = 0.04). No differences were observed in adiponectin levels in younger pregnant adolescents (< 16 years old) compared with older pregnant adolescents (≥ 16 years old). Adiponectin values were divided into 3 subgroups: < 3,000 ng/mL, between 3,000 and 5,000 ng/mL, and > 5,000 ng/mL. Birthweight was significantly higher in women > 5,000 ng/mL when compared with < 3,000 ng/mL in the adolescent group. No association between pregestational adiponectin levels and BMI, gestational weight gain, and gestational age was observed; however, there was a positive relation with birthweight (p = 0.0239). Conclusion Serum adiponectin values in pregnant adolescents between 30 and 36 weeks of gestation were higher compared with pregnant adults; however, no differences between younger and older pregnant adolescents were observed.

Abstract Background and Aims Urinary microRNA (miRNA)-21 is reported to be a biomarker for detection of acute kidney injury (AKI). Analysis of urinary exsome may serve as a novel diagnostic approach in kidney disease. The aim of this study is to investigate the clinical significance of urinary exosomal miRNA-21 for AKI in patients with scrub typhus. Method In a cross-sectional study, we collected 138 urine samples at the time of admission from 145 patients with scrub typhus. For 25 patients with scrub typhus-associated AKI and 25 age, sex-matched scrub typhus patient without AKI, we measured miRNA-21 in urinary exosomal fraction and compared diagnostic value in predictiong AKI. Results Compared with patients in the non-AKI group, patients in the AKI group were more likely to have one or more comorbidity such as diabetes (50% vs. 5%, P<0.01) and chronic kidney disease (8% vs. 0%, P<0.01). Total leukocyte count were higher in patients with AKI than in those without AKI (10.40 × 103/ mL vs. 6.40 × 103/mL, P<0.01). The levels of urinary miRNA-21 were higher in the AKI group than in the non-AKI group. Urinary exosomal miRNA-21 levels correlated directly with serum neutrophil gelatinase-associated lipocalin values and total leukocyte counts and inversely with estimated glomerular filtration rate. The receiver operator characteristics curve analysis for urinary exosomal miRNA-21 showed good discriminative power for the diagnosis of scrub typhus-associated AKI, with area under the curve value of 0.907. Conclusion Urinary exosomal miRNA-21 could be a surrogate markers for the diagnosis of scrub typhus–associated AKI.

Background: The soluble isoform of the interferon-β (IFN-β) receptor (sIFNAR2) could modulate the activity of both endogenous and systemically administered IFN-β. Previously, we described lower serum sIFNAR2 levels in untreated multiple sclerosis (MS) than in healthy controls (HCs). Objective: To assess sIFNAR2 levels in a new cohort of MS patients and HCs, as well as in patients with clinically isolated syndrome (CIS) and with other inflammatory neurological disorders (OIND) and to assess its ability as a diagnostic biomarker. Methods: The cross-sectional study included 148 MS (84 treatment naive and 64 treated), 87 CIS, 42 OIND, and 96 HCs. Longitudinal study included 94 MS pretreatment and after 1 year of therapy with IFN-β, glatiramer acetate (GA), or natalizumab. sIFNAR2 serum levels were measured by a quantitative ELISA developed and validated in our laboratory. Results: Naive MS and CIS patients showed significantly lower sIFNAR2 levels than HCs and OIND patients. The sensitivity and specificity to discriminate between MS and OIND, for a sIFNAR2 cutoff value of 122.02 ng/mL, were 70.1%, and 79.4%, respectively. sIFNAR2 increased significantly in IFN-β-treated patients during the first year of therapy in contrast to GA- and natalizumab-treated patients who showed non-significant changes. Conclusion: The results suggest that sIFNAR2 could be a potential diagnostic biomarker for MS.

Introduction: Interleukin L-17 is produced by Th 17 cells and other cells. There is a debate if IL 17 is atherogenic or atheroprotective. The true role of this interleukin during the development and progression of the coronary artery disease is not known. Objective: To evaluate if there are differences between the IL17 A serum levels according to clinical presentation of the coronary artery disease. Methods: This is a cross sectional study which enrolled 101 patients with acute coronary syndrome (ACS), 100 patients with chronic coronary syndrome (CCS) and 100 healthy volunteers. Blood samples were taken from patients ( at admission) and controls to analysis the level of IL17A. Clinical characteristics were collected through questionnaires. This research was approved by ethical committee. Results: Comparisons of the clinical characteristics between patients with ACS and CCS revealed: mean age ( 62 ± 12.4 vs 63.3 ± 9.8, p = 0.4 ), male (63.4% vs 58%, p = 0.4) hypertension (85.1% vs 79%, p = 0.1) , disyipidemia (48% vs 31%, p =0.01), Diabetes Mellitus (47.5% vs 41%, p = 0.3), previous myocardial infarction (57.4% vs 40%, p = 0,01), smoking (29.7% vs 38%, p = 1). The peripheral concentrations of IL17A according to ACS, CCS and controls were: 5.36 ± 8.83 vs 6.69 ± 17.92 vs 6.26 ± 11.13, p = 0.6. Besides, the comparison between ACS and CCS showed: 5.36 ± 8.83 vs 6.69 ± 17.92, p = 0.3. Conclusion: The main finding os this study was that the circulating IL 17 concentrations were similar in patients with ACS, CCS and healthy volunteers). Besides, there was no difference between patients with ACS and CCS. Therefore, our hypothesis is that in patients with ACS and CCS the circulating IL 17 A concentrations are low or undetectable.

Objective: Recent reports have suggested that the existence of associations between hormonal dysregulation and chronic upregulation of inflammatory markers, which may cause obesity-related disturbances. Thus, we examined whether acylated ghrelin (AcylG) and total ghrelin (TotG) levels could be associated with the following inflammatory markers: C-reactive protein (CRP), tumor necrosis factor α (TNF-α), and soluble TNF receptor 1 (sTNF-R1). Design: Cross-sectional study consisting of 50 overweight and obese postmenopausal women. Methods: AcylG and TotG levels were assessed at 0, 60, 160, 170, and 180 min of the euglycemic/hyperinsulinemic clamp (EHC). We evaluated insulin sensitivity, body composition, and blood lipid profiles as well as fasting concentrations of CRP, TNF-α, and sTNF-R1. Results: In fasting conditions, sTNF-R1 was negatively correlated with AcylG (r = −0.48, P < 0.001) levels. In addition, AcylG/TotG was associated negatively with sTNF-R1 (r = −0.44, P = 0.002) and positively with TNF-α (r = 0.38, P = 0.009) values. During the EHC, TotG (at all time points) and AcylG (at 60 and 160 min) values were significantly decreased from fasting concentrations. AcylG maximal reduction and area under the curve (AUC) values were correlated to sTNF-R1 (r = −0.35, P = 0.02 and r = −0.34, P = 0.02, respectively). Meanwhile, the AcylG/TotG AUC ratio was associated negatively with sTNF-R1 (r = −0.29, P < 0.05) and positively with TNF-α (r = 0.36, P = 0.02). Following adjustments for total adiposity, sTNF-R1 remained correlated with fasting and maximal reduction AcylG values. Similarly, AcylG/TotG ratios remained significantly correlated with sTNF-R1 and TNF-α. Importantly, 23% of the variation in sTNF-R1 was independently predicted by fasting AcylG. Conclusion: These results are the first to suggest that both fasting and EHC-induced AcylG profiles are correlated with fasting values of sTNF-R1, a component of the TNF-α system. Thus, AcylG may act, at least in part, as one mediator of chronic inflammatory activity in human obesity.

Fetal Antigen

Objective. Recent data suggest that fetal antigen (FA1) is linked to disorders of body weight. Thus, we measured FA1 serum levels in two extreme nutritional states of morbid obesity (MO) and anorexia nervosa (AN) and monitored its response to weight changes. Design. FA1 and insulin serum concentrations were assessed in a cross-sectional study design at defined time points after gastric restrictive surgery for 25 MO patients and 15 women with AN. Results. Absolute FA1 serum levels were within the assay normal range and were not different between the groups at baseline. However, the ratio of FA1/BMI was significantly higher in AN. FA1 was inversely correlated with BMI before and after weight change in AN, but not in MO patients. In addition, MO patients displayed a significant concomitant decrease of FA1 and insulin with the first 25% of EWL, while in AN patients a significant increase of FA1 was observed in association with weight gain. Conclusion. FA1 is a sensitive indicator of metabolic adaptation during weight change. While FA1 serum levels in humans generally do not correlate with BMI, our results suggest that changes in FA1 serum levels reflect changes in adipose tissue turnover.
