OBJECTIVE: The aim of this study was to evaluate changes in the relative counts of different leukocyte subsets in peripheral and umbilical cord blood in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) with respect to the presence of intraamniotic inflammation (IAI) and fetal inflammatory response syndrome (FIRS). METHODS: Fifty-two women with singleton pregnancies complicated by PPROM were included in this study. From samples of peripheral and umbilical cord blood, relative counts of these leukocyte subpopulations were determined using multicolor flow cytometry: granulocytes, monocytes, lymphocytes, T cells and their subpopulations, B cells and their subpopulations, and NK cells and their subpopulations. IAI was defined as increased concentrations of interleukin 6 in the amniotic fluid. Amniotic fluid samples were obtained by transabdominal amniocentesis. RESULTS: Women with IAI had higher relative counts of monocytes (p = 0.04) in peripheral blood. There was an increased relative number of granulocytes (p = 0.003) and a decreased number of lymphocytes (p = 0.0048), helper CD4+ T cells (p = 0.019), NK cells (p = 0.0001) within leukocytes, NK cells within lymphocytes (p = 0.003) and CD16+ NK cells within NK cells (p = 0.005) in umbilical cord blood samples of women with FIRS. However, after adjusting the results for gestational age at sampling, all differences disappeared. CONCLUSIONS: The presence of IAI or FIRS is not accompanied by significant changes in the relative counts of immune cells in peripheral blood or umbilical cord blood in pregnancies complicated by PPROM.

BACKGROUND: This study aimed to assess variations in the absolute counts of various leukocyte subsets in the peripheral blood of women with pregnancies affected by preterm prelabour rupture of membranes (PPROM), in relation to the presence of intra-amniotic inflammation (IAI). METHODS: The study included fifty-two women with singleton pregnancies experiencing PPROM. Absolute counts of different leukocyte subpopulations, such as granulocytes, monocytes, lymphocytes, T cells and their subsets, B cells and their subsets, and NK cells and their subsets, were measured in maternal peripheral blood samples using multicolour flow cytometry. IAI was identified by elevated concentrations of interleukin 6 (IL-6) in the amniotic fluid, which was collected through transabdominal amniocentesis. RESULTS: Women with IAI exhibited higher absolute counts of leukocytes (p = 0.003), granulocytes (p = 0.008), and monocytes (p = 0.009). However, the presence of IAI did not significantly affect the absolute counts of lymphocytes or their subpopulations. CONCLUSIONS: The study found that IAI is associated with changes in the absolute counts of leukocytes from the innate immunity compartment in the peripheral blood of women with pregnancies complicated by PPROM. Conversely, it does not significantly alter the counts of cells from the adaptive immune system. The changes observed may reflect the natural, temporal, and localised characteristics of IAI.

INTRODUCTION: The aim of the study was to identify predictive values of the soluble fms-like tyrosine kinase/placental growth factor (sFlt-1/PlGF) ratio and interleukin (IL)-6, assessed with a clinically available method in a large-volume biochemistry laboratory, in maternal blood, amniotic fluid, and umbilical cord blood for the presence of the placental lesions consistent with maternal vascular malperfusion (MVM) and acute histological chorioamnionitis (HCA), respectively. METHODS: This retrospective study included 92 women with preterm labor with intact membranes (PTL) delivered within 7 days of admission with gestational ages between 22+0 and 34+6 weeks. The sFlt-1/PlGF ratio and IL-6 were assessed in stored samples of maternal serum, amniotic fluid, and umbilical cord serum using Elecsys® sFlt-1, PlGF, and IL-6 immunoassays. RESULTS: Women with MVM had a higher sFlt-1/PlGF ratio in the maternal serum, compared to those without MVM (19.9 vs. 4.6; p < 0.0001), but not in the amniotic fluid or umbilical cord blood. A cut-off value of 8 for the sFlt-1/PlGF ratio in maternal serum was identified as optimal for predicting MVM in patients with PTL. Women with HCA had higher concentrations of IL-6 in maternal serum, compared to those without HCA (11.1 pg/mL vs. 8.4 pg/mL; p = 0.03), amniotic fluid (9,216 pg/mL vs. 1,423 pg/mL; p < 0.0001), and umbilical cord blood (20.7 pg/mL vs. 10.7 pg/mL, p = 0.002). Amniotic-fluid IL-6 showed the highest predictive value. A cut-off value of IL-6 concentration in the amniotic fluid of 5,000 pg/mL was found to be optimal for predicting HCA in PTL. CONCLUSION: Maternal serum sFlt-1/PlGF and amniotic fluid IL-6 concentrations can be used for liquid biopsy to predict placental lesions in women with PTL who deliver within 7 days.

This study aimed to investigate the effects of a single bench press (BP) vs. leg press (LP) resistance training sessions on testosterone, cortisol, C-reactive protein (CRP) interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) concentrations, and creatine kinase (CK) activity in strength-trained males. Eleven strength-trained males participated in a cross-over randomized trial, undergoing two experimental sessions each consisting of five sets of the BP or the LP exercise to volitional failure with a load corresponding to 50% of one-repetition maximum. Blood samples were taken at baseline (BA), immediately post (POST), and 1 h after the cessation of exercise (POST-1). A significant increase in IL-6 concentration from BA to POST-1 was observed during the LP condition (p = 0.004; effect size [ES] = 0.64). Additionally, a significant main effect of time was found for increasing testosterone concentrations from BA to POST exercise (p = 0.014; ES = 0.25). A significantly lower cortisol concentration at POST-1 compared to POST (p = 0.001; ES = 1.02) was noted in the BP condition. Furthermore, a significantly lower cortisol concentration was found at POST-1 in the BP compared to the LP condition (p = 0.022; ES = 1.3). A significant increase in CK activity was reported from BA to POST (p = 0.024; ES = 0.69) and POST-1 (p = 0.045; ES = 0.55) during the LP condition, and from BA to POST-1 (p = 0.014; ES = 0.96) during the BP condition. No significant differences were found in the CRP (p = 0.659) and TNF-α concentrations (p = 0.487). These results suggest that the amount of muscle mass engaged during the resistance exercise may influence the changes in IL-6 and cortisol concentrations. Larger muscle groups, as engaged in the LP, more likely lead to elevated concentrations of IL-6 myokine.

INTRODUCTION: Chronic effects of noninvasive ventilation on myocardial function in patients with obesity hypoventilation syndrome (OHS) are scarcely understood. The aim of the present study was to evaluate the long-term effects of volume-targeted bilevel positive airway pressure ventilation (BiPAP) on cardiac parameters and myocardial biomarkers in patients with OHS. METHODS: Clinically stable patients with OHS referred to the tertiary center for the initiation of long-term BiPAP therapy were consecutively enrolled. At baseline, all participants underwent overnight cardiorespiratory polygraphy. BiPAP therapy using volume-targeted spontaneous/timed mode delivered via an oro-nasal mask was initiated. Beat-to-beat noninvasive monitoring by impedance cardiography was used to assess heart function at baseline and after 3 and 12 months of BiPAP use. Serum troponin 1, N-Terminal Pro-B-Type Natriuretic Peptide (NT-ProBNP), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) were monitored. RESULTS: Thirteen patients (10 men; mean age, 55.8 ± 9.8 years; mean body mass index of 47.8 ± 5.9 kg/m2) were recruited. From baseline to 3, and to 12 months of BiPAP use, left ventricular stroke volume (SV), ejection time (LVET), and ejection time index significantly increased (P = 0.030; P < 0.001; P = 0.003, respectively), while heart rate and systolic time ratio significantly decreased (P = 0.004; P = 0.034, respectively). Reductions in serum NT-proBNP, IL-6 and TNF-α were observed (P = 0.045; P = 0.018; P = 0.003, respectively). No significant changes in serum troponin were detected throughout the study. CONCLUSIONS: The present findings of increased SV, in association with lengthening of LVET, reductions of NT-proBNP and reductions in circulatory inflammatory markers in patients with stable OHS and chronic moderate-to-severe daytime hypercapnia treated with BiPAP over 1 year support the role of this therapeutic mode in such patients.

Úvod: Cílem této studie bylo porovnat hodnoty interleukinu-6 v pupečníkové a periferní krvi novorozence. Klinickým cílem bylo zjistit, zda lze vyšetřením krve z pupečníku nahradit brzký postnatální odběr periferní krve. Pacienti a metody: Do studie byli zahrnuti novorozenci (< 35. týden gestace) narození v roce 2016–2018 ve Fakultní nemocnici Olomouc. U těchto novorozenců se zároveň podařilo odebrat dostatečné množství krve z pupečníku. Výsledky: Párový odběr se zdařil u 73 novorozenců. Mezi pupečníkovou a periferní hodnotou interleukinu-6 byl zjištěn výz­namný rozdíl (p < 0,001). Medián prvního měření (pupečníková krev) byl 6,5 ng/l, medián druhého měření (periferní krev) 56 ng/l. Nárůst je téměř desetinásobný. Závěr: Hodnoty interleukinu-6 z pupečníkové krve a z časného postnatálního odběru se podstatně liší. Na tuto skutečnost je nutné myslet při jeho klinickém využití.

Introduction: The aim of this study was to compare interleukin-6 values in umbilical cord and peripheral blood of newborns. The clinical goal was to determine whether the examination of cord blood can replace early postnatal peripheral blood collection. Patients and methods: Study included premature newborns (< 35th week of gestation) born in 2016-2018 at Olomouc University Hospital. At the same time, it was possible to collect a sufficient amount of blood from the umbilical cord in these newborns. Results: Paired sampling was successful in 73 of these newborns. A significant difference (p < 0,001) was found between the umbilical cord and peripheral interleukin-6 values. The median of the first measurement (cord blood) was 6,5 ng/l, the median of the second measurement (peripheral blood) was 56 ng/l. The increase is almost ten times bigger. Conclusion: The difference of values between interleukin-6 from umbilical cord blood and from early postnatal collection are significantly different and it is necessary to keep it in mind during its clinical use.

Background: Disruption of the IL-6 axis can result in the beginning or progression of a variety of disease states, including cardiovascular diseases. Because of IL-6's pathogenic function, pharmacologic manipulation of the IL-6 axis is a sensible therapeutic strategy; nevertheless, various expected, yet frequently overlooked, effects on tissues and organs other than blood vessels may also occur. The study's goal is as follows: The purpose of this study is to see how inflammatory Interleukin-6 affects the development of coronary artery disease.Materials and Methods: Serum IL-6 level was estimated using Elabscience® kits. A case-control study included 30 CAD patients, 30 positive controls (PC) [(have family history for CAD)], and 30 negative controls (NG) [they have no family history for CAD]. Ranged from 30 to 81 years old. Patients with acute or chronic illnesses such as liver disease, renal disease, thyroid function disorders, COVID-19, and autoimmune disease were excluded from the study. During the period from December 2020 to May 2021. Our study was included other factors such as ages, genders, smoking, family history, antihypertensive drugs or drugs for other diseases, body mass index (BMI) which were assessed.Results: The results of this study show increased levels of IL-6 in patients with CAD compared with the PC and NC These results showed a highly significant difference (p < 0.0001) in the concentrations compared with PC and NC.Conclusions: IL-6 could be one of the prognostic signs of CAD.

BACKGROUND: Preoperative plasma levels of Interleukin 6 (IL6) and its soluble receptor (IL6sR) have previously been associated with oncologic outcomes in urothelial carcinoma of the bladder (UCB); however, external validation in patients treated with radical cystectomy (RC) for UCB is missing. PATIENTS/METHODS: We prospectively collected preoperative plasma from 1,036 consecutive patients at two institutes. These plasma specimens were assessed for levels of IL6 and IL6sR. Logistic and Cox regression analyses were used to assess the correlation of plasma levels with pathologic and survival outcomes. The additional clinical net benefits of preoperative IL6 and IL6sR were evaluated using decision curve analysis (DCA). RESULTS: Median IL6 and IL6sR plasma levels were significantly higher in patients with adverse pathologic features. Elevated biomarker levels were independently associated with an increased risk for lymph node metastasis and ≥ pT3 disease. Both biomarkers were independently associated with recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). The addition to, respectively, fitted pre- and postoperative prognostic models improved the predictive accuracy for lymph node metastasis, ≥ pT3 disease, RFS and CSS on DCA. INTERPRETATION: We confirmed that elevated preoperative plasma levels of IL6 and IL6sR levels are associated with worse oncological disease survival in patients treated with RC for UCB in a large multicenter study. Both biomarkers hold potential in identifying patients with adverse pathological features that may benefit from intensified/multimodal therapy and warrant inclusion into predictive/prognostic models. They demonstrated the ability to improve the discriminatory power of such models and thus guide clinical decision making.
