Plasma insulin, leptin, adiponectin, resistin, ghrelin, and melatonin in nonalcoholic steatohepatitis patients treated with melatonin.

Insulin resistance, oxidative stress, and an abnormal production of adipokines and cytokines are implicated in the pathogenesis of nonalcoholic steatohepatitis (NASH). Recently, we reported a significant improvement in plasma liver enzymes among patients with NASH treated with melatonin. In this study, we investigated the effect of melatonin, administered at a dose of 10 mg/day for 28 days to 16 patients with histologically proven NASH on insulin resistance (HOMA-IR), on the plasma levels of adiponectin, leptin, ghrelin, and resistin. Additionally, plasma levels of aminotransferases and gamma glutamyltranspeptidase as well as plasma concentrations of melatonin were evaluated. Median baseline values of HOMA-IR, leptin (ng/mL), and resistin (pg/mL) in patients with NASH were significantly higher in comparison with controls: 4.90 versus 1.60, 10.70 versus 4.30, and 152 versus 91, respectively. Median adiponectin level (µg/mL) was decreased in patients compared to controls: 6.40 versus 16.25; no significant difference in ghrelin levels between patients and controls was found. After melatonin treatment, the median value of HOMA-IR was significantly reduced by 60% as compared to baseline values, whereas adiponectin, leptin, and ghrelin plasma levels rose significantly by 119%, 33%, and 20%, respectively; the difference between pre-/posttreatment in plasma resistin levels was not significant. These findings make melatonin a suitable candidate for testing in patients with NASH in the large controlled clinical trials.

Evaluation of Parameters Affecting the Occurrence of Systemic Inflammatory Response Syndrome in Patients Operated on Due to Kidney Tumors.

The application and prognostic nature of systemic inflammatory reaction syndrome (SIRS) is still being researched, as using SIRS parameters to predict patient status is cheap, efficient, fast, and easy. The study aimed to determine SIRS markers and postoperative complications occurrence in patients undergoing kidney tumor surgery, and to verify if SIRS occurrence depends on age, sex, BMI (body mass index), comorbidities, patients' general condition before the surgery, type of surgery, intraoperative blood loss, or intraoperative ischemia time. Body temperature, heart rate, respiratory rate, and leukocyte count were measured in patients (n = 285) operated on due to a kidney tumor on the first (T0) and third (T3) postoperative day. Univariable and multivariable logistic regression were used to analyze the factors affecting postoperative SIRS and complications occurrence. T0: SIRS developed in patients with higher BMI, >2 ASA points, and more substantial intraoperative blood loss. T3: SIRS developed in obese or overweight patients, with >2 ASA points, significantly higher relative HR change, lower relative body temperature change, respiratory rate, and leukocyte count. BMI values, preoperative general health status, and the amount of intraoperative blood loss in patients undergoing surgery due to a kidney tumor can contribute to SIRS occurrence. Patient's sex, age, tumor size, type of surgery, operated side, and time of intraoperative ischemia do not affect SIRS occurrence.

VEGF and metalloproteinase 2 (MMP 2) expression in gastric cancer tissue.

BACKGROUND: Neoplasms are the second leading cause of death in Poland after vessel diseases, despite the huge progress in medical sciences in the last 20 years. Recently, gastric cancer morbidity has decreased, but mortality is still at a high level. MATERIAL/METHODS: Tissues from 24 patients with a histopathologically diagnosed mucosal and adenomucosal gastric cancer were tested. Patients were divided into 2 equal groups: patients without metastases (G1) and patients with metastases in the liver (G2). In all tested tissues of G1 and G2, the expression of VEGF (vascular endothelial growth factor) and metalloproteinase 2, respectively, were estimated. RESULTS: Results revealed a statistically significant increase in the VEGF expression for G1 and G2 in relation to the margin (p1<0.001; p2<0.001). The increase of gene expression for VEGF did not significantly differ statistically in G1 and G2. The obtained results revealed a statistically significant difference in the increase of gene expression for MMP-2 in G1 in relation to the margin (p<0.05) and a very high one in G2 in relation to the average margin value (p<0.001). A highly statistically significant correlation was obtained for VEGF and MMP-2 in the tissue of patients with metastases (p<0.001; r=0.714). The highly elevated expression of MMP-2 in the tissue of gastric cancer in patients with metastases confirms its participation in the invasiveness of the neoplasmatic process. CONCLUSIONS: The highly significant correlation between VEGF and MMP-2 suggests a connection between both mechanisms in the progression of gastric cancer.

Personalised Approach to Diagnosing and Managing Ischemic Stroke with a Plasma-Soluble Urokinase-Type Plasminogen Activator Receptor.

BACKGROUND: The increasing incidence of ischemic stroke has led to the search for a novel biomarker to predict the course of disease and the risk of mortality. Recently, the role of the soluble urokinase plasminogen activator receptor (suPAR) as a biomarker and indicator of immune system activation has been widely examined. Therefore, the aim of the current study was to assess the dynamics of changes in serum levels of suPAR in ischemic stroke and to evaluate the prognostic value of suPAR in determining mortality risk. METHODS: Eighty patients from the Department of Neurology, diagnosed with ischemic stroke, were enrolled in the study. Residual blood was obtained from all the patients on the first, third and seventh days after their ischemic stroke and the concentrations of suPAR and C-reactive protein (CRP), as well as the number of leukocytes and National Institute of Health's Stroke Scale (NIHSS) scores, were evaluated. RESULTS: On the first day of ischemic stroke, the average suPAR concentration was 6.55 ng/mL; on the third day, it was 8.29 ng/mL; on the seventh day, it was 9.16 ng/mL. The average CRP concentration on the first day of ischemic stroke was 4.96 mg/L; on the third day, it was 11.76 mg/L; on the seventh day, it was 17.17 mg/L. The number of leukocytes on the first day of ischemic stroke was 7.32 × 103/mm3; on the third day, it was 9.27 × 103/mm3; on the seventh day, it was 10.41 × 103/mm3. Neurological condition, which was assessed via the NIHSS, on the first day of ischemic stroke, was scored at 10.71 points; on the third day, it was scored at 12.34 points; on the seventh day, it was scored at 13.75 points. An increase in the values of all the evaluated parameters on the first, third and seventh days of hospitalisation was observed. The patients with hypertension, ischemic heart disease and type 2 diabetes showed higher suPAR and CRP concentrations at the baseline as well as on subsequent days of hospitalisation. The greatest sensitivity and specificity were characterised by suPAR-3, where a value above 10.5 ng/mL resulted in a significant increase in mortality risk. Moreover, an NIHSS-1 score above 12 points and a CRP-3 concentration above 15.6 mg/L significantly increased the risk of death in the course of the disease. CONCLUSIONS: The plasma suPAR concentration after ischemic stroke is strongly related to the patient's clinical status, with a higher concentration on the first and third days of stroke resulting in a poorer prognosis at a later stage of treatment. Therefore, assessing the concentration of this parameter has important prognostic value.

Plasma homocysteine concentrations in mothers and term and preterm newborns.

AIM: To assess the correlation between homocysteine concentrations and gestational age, gender Apgar score, complications in pregnancy delivery modalities and levels of vitamin B12 and foliate. MATERIAL AND METHODS: Concentration of homocysteine, vitamins-B12, foliate were measured in cord blood and mother blood. There were 40 full-term babies and 38 preterm babies and their mothers. RESULT: The homocysteine concentration in newborns correlated with homocysteine level in mothers. There was no difference in homocysteine level regardless of newborns gender. There was no correlation in the homocysteine concentration of mothers blood and cord blood with the levels of vitamin 812 and foliate. In full-term newborns a significant increase in homocysteine levels in comparison with premature babies was observed (7.2 +/- 1.4 micromol/ vs. 6.4 +/- 1.3 micromo/l; p = 0.01). Additionally negative correlation between the mothers' age and homocysteine concentration (r = -0.23; p = 0.04) and positive correlation between homocysteine concentration in cord plasma and gestation age (r = 0.28; p = 0.01) were found. CONCLUSION: Homocysteine concentration depends on gestational age, Apgar score and mother's age. There is no correlation between homocysteine level and hypertension during pregnancy type of delivery levels of vitamin 812 and foliate. Determination of homocysteine level is therefore of no significant importance in newborns pathophysiology.

[Usefulness of evaluation of soluble fragment cytokeratin 18, carcinoembryonic antigen and gastrointestinal carcinoma-associated antigen in diagnostic of patients with colorectal cancer]. / Przydatnosc oznaczen rozpuszczalnego fragmentu cytokeratyny 18., antygenu karcynoembrionalnego oraz mucynopochodnego antygenu (CA 19-9) w diagnostyce chorych na raka okreznicy i odbytnicy.

Colorectal cancer is one of the most frequent malignant neoplasms which affects humans. Last year studies indicate a constantly increasing inception rate. Multidisciplinary teams direct all their efforts towards detection of cancer in it's asymptomatic phase. In parallel with development of diagnostic imaging is development of clinical immunodiagnostics. The last allows for quantitative determination of active neoplasmic process markers. In the following article authors show the most frequent markers used in immunodiagnostic. Colorectal cancer known as "tumor burden markers CEA, CA 19-9 as well as the "new one" tissue polypeptide specific antigen proliferation marker--TPS.

Evaluation of serum human epididymis protein 4 in patients with relapsing-remitting multiple sclerosis.

BACKGROUND: So far, little is known about the properties of human epididymis protein 4 (HE4) in multiple sclerosis (MS). This type 4 glycoprotein belongs to a family of genes encoding proteins whose expression is associated with the process of spermatogenesis in the epididymis. The biological function of HE4 is not fully understood. Overexpression of HE4 has been found in several malignant tumors, particularly in ovarian cancer, as well as in mesothelioma, lung, endometrial, breast, and kidney cancers. OBJECTIVES: To evaluate serum HE4 in patients with relapsing-remitting multiple sclerosis (RRMS) as compared to healthy controls. MATERIAL AND METHODS: Fifty patients with RRMS undergoing first-line immunomodulatory treatment were enrolled in the prospective study. We analyzed correlations between serum HE4 levels and gender, age, disease duration, the Expanded Disability Status Scale (EDSS), annualized relapse rate (ARR), and magnetic resonance imaging (MRI) lesions. RESULTS: The patients from the study group had higher concentrations of HE4 than the subjects from the control group. Patients with EDSS > 2 had significantly higher concentrations of HE4. Positive correlations were found between HE4 concentrations and age as well as between HE4 concentrations and disease duration. No significant correlations were found between HE4 concentrations and EDSS or between HE4 concentrations and ARR. CONCLUSIONS: The results of the study indicate a novel aspect of the HE4 protein in the pathomechanisms of MS.

The Association between Serum Levels of 25[OH]D, Body Weight Changes and Body Composition Indices in Patients with Heart Failure.

We try to determine the association between weight changes (WC), both loss or gain, body composition indices (BCI) and serum levels of 25[OH]D during heart failure (HF). WC was determined in 412 patients (14.3% female, aged: 53.6 ± 10.0 years, NYHA class: 2.5 ± 0.8). Body fat, fat percentage and fat-free mass determined by dual energy X-rays absorptiometry (DEXA) and serum levels of 25[OH]D were analyzed. Logistic regression was used to calculate odds ratios for 25[OH]D insufficiency (<30 ng/mL) or deficiency (<20 ng/mL) by quintiles of WC, in comparison to weight-stable subgroup. The serum 25[OH]D was lower in weight loosing than weight stable subgroup. In fully adjusted models the risk of either insufficient or deficient 25[OH]D levels was independent of BCI and HF severity markers. The risk was elevated in higher weight loss subgroups but also in weight gain subgroup. In full adjustment, the odds for 25[OH]D deficiency in the top weight loss and weight gain subgroups were 3.30; 95%CI: 1.37-7.93, p = 0.008 and 2.41; 95%CI: 0.91-6.38, p = 0.08, respectively. The risk of 25[OH]D deficiency/insufficiency was also independently associated with potential UVB exposure, but not with nutritional status and BCI. Metabolic instability in HF was reflected by edema-free WC, but not nutritional status. BCI is independently associated with deficiency/insufficiency of serum 25[OH]D.

The diagnostic utility of S-100B protein and TPA in patients with ischemic stroke.

OBJECTIVE: The aim of the study is to asses blood plasma concentrations of S-100B protein and Tissue Polypeptide Antigen (TPA) in patients with confirmed ischemic stroke and to correlate these concentrations with stroke severity. METHODS: S-100B protein and TPA blood plasma concentrations were determined in 47 patients with acute ischemic infarction and in the control population. S-100B protein was assessed on the 1th day, TPA on the 1th, 7th and 14th day. The clinical status was documented using Scandinavian Stroke Scale. The functional deficit after the stroke was scored by Barthel Index. RESULTS: The analysis of the entire examined group in relation to the control population showed elevated concentrations of S-100B protein (0.47 ng/ml vs. 0.19 g/ml). The highest concentrations were in the severe stroke group (0.89 ng/ml). The assessment of TPA blood plasma concentrations showed higher ones in the examined group of patients: 225.7 U/l on the 1st day; 96.1 U/l on the 7th day; 125.64 U/l on the 14th day after the stroke in relation to the control population. CONCLUSION: The analysis of obtained results showed significant increase of S-100B protein blood plasma concentrations in patients with severe stroke and TPA in patients with mild stroke. S-100 protein blood plasma concentration assessed on the 1st day after the ischemic stroke is the parameter presenting the highest diagnostic utility and its value above 0.6 ng/ml was obtained only in patients with severe stroke.

Lipofuscin, homocysteine and tissue polypeptide specific antigen in gestational hypertension.

OBJECTIVE: The aim of this study were to assess the levels of lipofuscin (parameter of oxidative stress), homocysteine (as a marker of vascular injury) and tissue specific antigen - TPS - (as a marker of cell proliferation) in relation to arterial pressure of pregnant woman. STUDY DESIGN: Healthy pregnant women (n=18), women with mild 140/90=< RR<160/100 (n=19), and severe 160/100=

Homocysteine, folic acid and vitamin B12 concentration in patients with recurrent miscarriages.

OBJECTIVES: The aim of the project was the assessment of clinical usefulness of the determination of blood serum homocysteine concentration, folic acid and vitamin B12 in recurrent miscarriages. METHODS: 30 non-pregnant women with recurrent miscarriages (examined group-I) and for 20 non-pregnant women without obstetric failures in medical history (control group-II) were examined. RESULTS: In the examined group (group I), the average concentration of homocysteine (9,45 micromol/l) was not statistically higher in comparison to the control group (group II) (8,47 micromol/l) (p>0,05). In group I the average vitamin B12 concentration in blood serum was 178,3 pg/ml and it was statistically lower (p<0,001) in comparison with the control group (II) (268,6 pg/ml). Such a relation was not observed for the vitamin B12, where the average concentration of this parameter was not dependent on the miscarriage number. A high negative correlation (R= -0,5397, p<0,01) was observed between the level of folic acid and homocysteine concentration in the group of women with recurrent miscarriages and a very high negative correlation (r = -0,9586 p<0,001) in the control group. No relation (R=0,0992 p>0,05) between the average concentration of vitamin B12 in blood serum and the average homocysteine in the nullipara group with recurrent miscarriages CONCLUSIONS: Together with the increasing number of abortions, the average homocysteine concentrations grew and the average folic acid concentrations lowered.

Homocysteine serum concentration and uterine artery color Doppler examination in cases of recurrent miscarriages with unexplained etiology.

OBJECTIVES: To study the assessment of diagnostic value and clinical usefulness of the determination of homocysteine concentration in blood serum in cases of recurrent miscarriages and the relation between the concentration of homocysteine in blood serum and parameter values determining the Doppler blood flow in the uterine arteries. METHODS: Homocysteine concentration in blood serum was determined in a group of 30 women with at least two subsequent miscarriages with no clear reason and in the control group consisted of 20 non-pregnant women without a medical history of obstetric failures, having at least one healthy child. In all cases Color Doppler sonography was performed to determine flow velocity waveforms of the uterine arteries in luteal phase of the menstrual cycle. RESULTS: Both pulsatility (PI) and resistance indices (RI) were considerably higher (p<0.01, p<0.05) for the group of women with recurrent abortions. In the group of women with obstetrical failures high positive correlation (R=0.6903, p<0.001) and in the control group very high positive correlation (r=0.8163, p<0.001) was found, between average values of PI and average HC concentration. High positive correlation (R=0.6260, p<0.001) in the examined group and very high positive correlation (r=0.9201, p<0.001) in the control group was obtained between average values of RI, and average HC concentrations in blood serum . CONCLUSIONS: The recurring miscarriages occur in connection with the elevated homocysteine concentration, in consequence they can point out the pathology within the uterine-fetal blood vessels.

Is serum protein electrophoresis useful in separating the "high risk group" in patients with colonic polyps?

BACKGROUND: Adenomas have the highest potential or clinical value from among colonic polyps of developing into adenocarcinoma. The aims of this paper are: to establish criteria to identify the high risk group of patients in a group of patients with colonic polyps, to work out a simple scheme for follow-up care after endoscopic polypectomy, and to establish indications for surgery. The usefulness of determination of electrophoresis of serum proteins has been specially analysed to detect early development of malignant growths in patients with colonic polyps regarding alfa-1/alfa-2 and alfa/beta. 67 cases - 21 women, 46 men were tested. Follow-up endoscopy with the electrophoresis was performed after 6 weeks, 6 and 12 months after polypectomy. 97 polyps were resected with endoscopy in 67 patients. 38 patients (39.17%), those constituting the high risk group, were selected. Included were all polyps with grade II and III of cellular differentiation. CONCLUSIONS: 1) alfa-1/alfa-2 and alfa/beta is a helpful test in identifying the high risk group among patients with colonic polyps and it can be used as a screening test, 2) the determination of beta-2-macroglobuline is not useful in the diagnosis of this group of patients, 3) the electrophoresis of proteins should be the first test to perform on patients with colonic polyps. The relation of electrophoresis to endoscopic polypectomy aids evaluations of patients specially predisposed to malignant.

Expression of cell survival/death genes: Bcl-2 and Bax at the rate of colon cancer prognosis.

The rate of tumour growth is dependent on the balance between proliferation and apoptosis at all stages of carcinogenesis. Apoptosis inhibition, in turn, depends partly on the balance between expression of two cell death regulatory genes, Bcl-2 and Bax. Colon cancer has long been associated with disturbances in apoptosis regulation. The aim of our study was to determine the expression levels of Bcl-2 and Bax mRNAs in 1 microg sample of total RNA obtained from normal colon and colon adenocarcinoma. This study was intended to evaluate possible differences in Bcl-2 and Bax mRNA levels at particular stages of colon adenocarcinoma classified according to Duke's system. The apoptotic frequency (represented by Bax mRNA copy number) was inversely proportional to the decrease of Bcl-2 gene expression. Terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) was performed to confirm apoptosis.

Utility of serum concentration of protein S100 at admission to the medical intensive care unit in prediction of permanent neurological injury.

INTRODUCTION: Admission to the intensive care unit (ICU) may be preceded by dramatic events leading to permanent neurological injury. Plasma S100 protein levels are proved to be clinically useful in predicting neurological outcome following cardiac arrest. It is unclear, however, whether this may be extrapolated to a broader population of ICU patients. AIM: To assess the utility of plasma S100 protein in predicting death, permanent neurological damage, or unfavourable outcome at admission to the intensive care unit. MATERIAL AND METHODS: The concentration of plasma S100 protein was established in 102 patients on admission to the ICU, regardless of their neurological status and the reason for admission. The majority of patients were admitted with various cardiac diseases, excluding trauma patients. The patients were classified into three groups with the following binary outcomes: permanent neurological deficit or restoration of consciousness; unfavourable outcome (death or survival with permanent neurological deficit) or favourable outcome; and death or survival. RESULTS: Plasma S100 protein levels at admission facilitated the identification of patients who later developed a permanent neurological deficit or regained consciousness (p < 0.0001). All patients with plasma S100 protein over 0.532 µg/l at ICU admission either developed a permanent neurological deficit or had an unfavourable outcome (death or survival with permanent neurological deficit). However, sensitivity for this cut-off value was only 48% and 40%, respectively. CONCLUSIONS: Plasma S100 protein levels over 0.532 µg/l are specific but not sensitive for both permanent neurological deficit and unfavourable outcome when assessed in a heterogeneous population at admission to the ICU.

[Usefulness of evaluation of carcinoembryonic antigen (CEA) and soluble fragments of cytokeratin 18-th (TPS) in postoperative monitoring of patients with colorectal cancer]. / Przydatnosc oznaczen antygenu rakowoplodowego (CEA) i rozpuszczalnych fragmentów cytokeratyny 18-ej (TPS) w pooperacyjnym monitorowaniu chorych na raka okreznicy i odbytnicy.

BACKGROUND: The aim of this study is to diagnose the evaluation of concentration of CEA and TPS in postoperative monitoring of patients with colorectal cancer. PATIENTS AND METHODS: We measured 178 consecutive patients with histopathologically confirmed colorectal cancer: 101 men and 78 women ages 22-86 (average age 54.7). Markers' CEA nad TPS concentration were evaluated before operation and every month after operation during the first 3 months and then every 3 months during 2 years. Relapse was detected in 47 patients. RESULTS: In postoperative period in non-relapse group the mean (the average) concentration of CEA was 1.92+/-2.03 ng/ml and TPS 65.54+/-33.96 U/l and respectively in relapse group for CEA was 1.92+/-2.03 ng/ml and for TPS 65.54+/-33.96 U/l. The obtained results in investigated group show significantly statistical. The relapse was confirmed by using CEA concentration in 42 patients (89.4%). In case of TPS concentration relapse was confirmed in 38 patients (80.85%). The relapse was detected in 45 patients (95.74) if increase in CEA or TPS concentration was treated as a way of detecting relapse. TPS markers point out that the increase of TPS concentartion may be ahead of relapse symptoms at about 2-6 months. CONCLUSIONS: TPS is a useful marker in postoperative monitoring of patients with colorectal cancer. The evaluation of TPS concentration allow to diagnose the recurrence of colorectal cancer earlier than by using burden markers--CEA. Common evaluation of TPS and CEA increase sensitivity in detection of relapse in patients with colorectal cancer.

Higher serum phosphorus is associated with catabolic/anabolic imbalance in heart failure.

BACKGROUND: A higher serum phosphate level is associated with worse outcome. Energy-demanding intracellular transport of phosphate is needed to secure anion bioavailability. In heart failure (HF), energy starvation may modify intracellular and serum levels of phosphate. We analysed determinants of serum phosphates in HF and assessed if catabolic/anabolic balance (CAB) was associated with elevation of serum phosphate. METHODS: We retrospectively reviewed data from 1029 stable patients with HF and have calculated negative (loss) and positive (gain) components of weight change from the onset of HF till index date. The algebraic sum of these components was taken as CAB. The univariate and multivariable predictors of serum phosphorus were calculated. In quintiles of CAB, we have estimated odds ratios for serum phosphorus above levels previously identified to increase risk of mortality. As a reference, we have selected a CAB quintile with similar loss and gain. RESULTS: Apart from sex, age, and kidney function, we identified serum sodium, N-terminal fragment of pro-brain-type natriuretic peptide, and CAB as independent predictors of serum phosphorus. The odds for serum phosphorus above thresholds found in literature to increase risk were highest in more catabolic patients. In most catabolic quintile relative to neutral balance, the odds across selected phosphorus thresholds rose, gradually peaking at 1.30 mmol/L with a value of 3.29 (95% confidence interval: 2.00-5.40, P < 0.0001) in an unadjusted analysis and 2.55 (95% confidence interval: 1.38-2.72, P = 0.002) in a fully adjusted model. CONCLUSIONS: Metabolic status is an independent determinant of serum phosphorus in HF. Higher catabolism is associated with serum phosphorus above mortality risk-increasing thresholds.

[The usefulness of evaluation of: ferritin, ultrasensitive CRP and tissue specific polypeptide 18th (TPS) in assessment of therapy efficacy in patients with nasal polyps]. / Wartosc oznaczen wybranych parametrów diagnostycznych: ferrytyny, ultraczulego CRP i rozpuszczalnych fragmentów cytokeratyny 18. (TPS) w ocenie skutecznosci terapii chorych z polipami nosa.

BACKGROUND: Chronic rhinosinusitis with nasal polyps is social, clinical and cost-effective problem, by reason of bothersome symptoms, chronic nature of the disease, tendency to recur and lack of satisfying treatment. AIM: The aim of this study is assessment of suitability of hsCRP, ferritin and blood levels in nasal polyps patients in evaluation of treatment efficacy. METHODS: The study enrolled 38 patients between 20 and 68 years of age. Patients were divided into 2 groups. Levels of ultrasensitive CRP ferritin and TPS have been measured in all patients. The ultrasensitive CRP levels have been measured by chemiluminescence method. Ferritin levels have been measured by MEIA method. The TPS levels have been measured by chemiluminescence method. RESULTS: Comparison of mean ferritin levels in both study groups in each stage of observation shows the significant difference of mean values in only 6 weeks after surgery. Mean ferritin level is significantly lower in group I than in group II (p<0.05). Mean hsCRP levels vary from one corresponding to ferritin levels. Statistically significant difference between study groups in 2nd and 6th week after surgery has been ascertained (p<0.05). Similarly, like in ferritin levels, the TPS levels are significantly different in 6th week after surgery. CONCLUSIONS: Analysis of ferritin, hsCRP and TPS serum levels indicates that these may be useful in assessment of treatment efficacy in patients with nasal polyps. Rise of the chosen inflammatory state parameter level in the postoperative monitoring and anti-inflammatory treatment introduction in nasal polyps patients may inhibit the recurrence of the disease.

Antibodies against Hsp60 and Hsp65 in the sera of women with ovarian cancer.

BACKGROUND: The aim of this study was to evaluate the concentrations of IgG antibodies against Hsp60 and Hsp65 in sera of patients with ovarian cancer at various stages of clinical progress and for different histopathological types of disease. METHODS: Serum samples from 149 patients with ovarian carcinoma and 80 healthy women were investigated. The concentrations of anti-Hsp60 and anti-Hsp65 antibodies were determined using the enzyme-linked immunosorbent assay technique. RESULTS: The mean concentrations of anti-Hsp60 and anti-Hsp65 antibodies in the patients with ovarian cancer did not differ significantly from the mean levels in healthy women. Analysis in relation to the clinical progression stage showed that the concentrations of these antibodies were higher when the neoplastic process was less advanced and at early stages significantly higher than in control group. Mean concentrations of both antibodies were not significantly different in relation to the histological type of the ovarian cancer. The use of chemotherapy as a primary anticancer treatment did not cause a significant change in the concentration of anti-Hsp60 antibodies, but the mean level of anti-Hsp65 after this treatment was significantly higher than in control group. CONCLUSIONS: The immunological response to Hsp60/65 is increased in early clinical stages of ovarian cancer and the level of anti-hsp60/65 antibodies may be then a helpful diagnostic marker. Even antibodies against highly homologous Hsps may be cross-reactive only partially and differ by some functional properties.

Five-year survival of patients with chronic systolic heart failure of ischemic and non-ischemic etiology: analysis of prognostic factors.

INTRODUCTION: Despite advances in pharmacotherapy, electrotherapy and interventional treatment, chronic heart failure (HF) is still associated with poor long-term outcome. AIM OF THE STUDY: To determine the death rate and risk factors in patients with HF of ischemic and non-ischemic etiology in five-year follow-up. MATERIAL AND METHODS: Consecutive patients with chronic systolic HF hospitalized in the period 2006-2008 were analyzed retrospectively. Study exclusion criteria were: infections (< 3 months before hospitalization), hemodynamically significant valve disease, advanced chronic kidney disease, liver cirrhosis and neoplastic diseases (< 5 years before hospitalization). RESULTS: The analysis encompassed 266 patients divided into two groups: Group A, with HF of ischemic etiology (n = 157), and Group B, with HF of non-ischemic etiology (n = 109). Mortality was significantly higher in Group A than in Group B (49% vs. 28.4%, p = 0.001). The independent risk factors for death in Group A were: New York Heart Association (NYHA) class (HR = 1.81; p < 0.001); concentrations of high-sensitivity C-reactive protein (hs-CRP) (HR = 1.01; p < 0.05), fibrinogen (HR = 1.04; p < 0.001) and N-terminal prohormone brain natriuretic peptide (NT-proBNP) (HR = 1.02; p < 0.001); and right ventricular end-diastolic diameter (RVEDd) (HR = 1.07; p < 0.01). In Group B they were age (HR = 1.07; p < 0.05) and NT-proBNP concentration (HR = 1.03; p < 0.001). CONCLUSIONS: Mortality was significantly lower in Group B than in Group A. The independent risk factors for death in Group B were age and NT-proBNP serum concentration, whilst in Group A they were NYHA class, serum concentrations of hs-CRP, NT-proBNP and fibrinogen, and RVEDd.
