    Brain-type creatine kinase isoenzyme (CK-BB) was measured by radioimmunoassay in the serum of 54 patients with head injuries. CK-BB was not detectable in 476 out of 1006 controls, the remaining 530 normal samples containing a mean of 1.5 +- SDO.75 ..mu..g/l. The mean CK-BB concentrations in patients with mild, moderate, and fatal head injuries were all significantly higher than the control value (p<0.01 in each instance). Patients with serious head injury had serum concentrations many times the normal value, in two cases within 30 minutes after impact. Fatally injured patients continued to have high serum concentrations several days after injury. In less serious cases values approached normal within two or three days. Every patient with evidence of cerebral laceration, bruising, or swelling had a serum CK-BB concentration above normal. Raised concentrations were found in 14 out of 22 patients with concussion only. Thus the serum CK-BB concentration appears to be a sensitive index of brain damage and may prove useful in the management and follow-up of head-injured patients.

    The measurement of creatine kinase BB isoenzyme (CK-BB) using RIA methods could have diagnostic utility as a biological marker of cerebral damage. The aim of the present study is to evaluate whether frequent sampling (4 samples/day for 3 days) permits a better correlation between serum CK B B values and the clinical outcomes of patients with cerebrovascular accidents. 16 in-patients (12 men and 4 women) with stroke (15 of an ischemic nature and 1 hemorrhagic) have benn studied. The presence of stroke was confirmed by clinical symptoms and by CAT results. Blood samples were drawn at 6 and 12 a.m. and at 6 and 12 p.m. over 3 consecutive days after hospitalization. Values of serum CK-BB above the normal range (>7 ng/ml) were found in the 5 of the 16 (31.3%) patients studied. The mean CK-BB value observed in the patients' group was significantly higher than that found in a group of 112 control subjects (controls, mean+-SD=2.1+-1.7 ng/ml vs patients 3.3+-3.4 ng/ml, unpaired t-test p<0.025). We observed a very wide range of serum CKBB levels in most of the patients studied. Some prominent peaks of CK-BB concetrations were found in patients' outcame (Spearman correlation coefficient r-s=0.618, p<0,01). Although our results indicate that the measurement of CK-BB concentrations cannot be considered a sensitive marker of stroke, the significant correlation between serum CK-BB values and outcome suggests that high CK-BB levels could be a sign of worse prognosis in patients with cerebrovascular accidents

    Full Text Available Objective: To find out an easy and feasible test instead of cerebrospinal fluid analysis for the diagnosis of acute meningitis. Methods: This cross-sectional study was conducted in 2013 in Ahvaz, a city located in the Southwest Iran including 75 patients with clinical diagnosis of fever, headache, vomiting and neck stiffness suspected to have acute meningitis based on cerebrospinal fluid analysis. In the beginning, the patients were divided into two categories as acute meningitis, and non-acute meningitis. Then, 5 L of blood was taken from each patient to determine serum creatine kinase isoenzyme-BB by using ELISA method. After that, the related data including demographics, clinical and laboratory results were analyzed by SPSS software version 16 using Chi-square test for qualitative variables and student’s t-test for quantitative variables. Results: Among the total 75 patients, 37 (49.3% were males and 38 (50.7% were females including 45 patients (60% with acute meningitis and 30 patients (40% without acute meningitis. On the other hand, CK-BB serum levels in acute meningitis and non-acute meningitis patients were 18.23 ± 7.56 and 2.67 ± 1.62, respectively, so significant difference was found between acute meningitis group and non-acute meningitis group (P < 0.000 1. Conclusions: Serum creatine kinase isoenzyme-BB test is a useful test to differentiate acute meningitis from non-acute meningitis among suspected cases of meningitis disease, so measuring the CK-BB serum level in Iran's health system with an expanded health setting especially in remote areas will be useful and helpful in prompt diagnosis and treatment of the acute meningitis.

    The article is to study the clinical significance of serum CA19-9 in diagnosing malignant tumor occurred in digestive system and to select cut off values for differentiating diagnosis of a pancreatic neoplasms and pancreatitis. Using chemiluminescence immunoassay, serum CA19-9 level of below subjects were analyzed: control group (n=21); digestive system neoplasm group (n=125, with 7 cases conformed as pancreatic cancer); non-neoplastic disease group (n=387, with 15 cases conformed as pancreatitis secondary to destructive cholangitis). Receiver operating characteristic (ROC) curve was used for analyzing results and selecting cut off values. When cut off value was 18.4 kU/L, sensibility for conforming a digestive system neoplasm was 60.8%, while its related specificity against control group and non-neoplastic disease group was 95. 2% and 68.2%, respectively. Sensibility for diagnosing pancreatic neoplasm was 85.7%, while its related specificity against control group and non-pancreatic origin tumor group was 95.0% and 63.1%, respectively. When 37 kU/L was chosen as cut off value, specificity for differentiating diagnosis of pancreatic neoplasm and pancreatitis secondary to destructive cholangitis rose from 13.3% to 46.7%. Serum CA19-9 could be used as an aid in detecting digestive system neoplastic disease; it is a reliable marker for pancreatic neoplasm. Raising cut off value may help to differentiate pancreatic neoplasm and pancreatitis secondary to destructive cholangitis

    Full Text Available BACKGROUND: Renal failure in neonates is associated with an increased risk of mortality and morbidity. But critical values are not known. OBJECTIVE: To define critical values for serum creatinine levels by gestational age in preterm infants, as a predictive factor for mortality and morbidity. STUDY DESIGN: This was a retrospective study of all preterm infants born before 33 weeks of gestational age, hospitalized in Nantes University Hospital NICU between 2003 and 2009, with serum creatinine levels measured between postnatal days 3 to 30. Children were retrospectively randomized into either training or validation set. Critical creatinine values were defined within the training set as the 90(th percentile values of highest serum creatinine (HSCr in infants with optimal neurodevelopmental at two years of age. The relationship between these critical creatinine values and neonatal mortality, and non-optimal neural development at two years, was then assessed in the validation set. RESULTS AND CONCLUSION: The analysis involved a total of 1,461 infants (gestational ages of 24-27 weeks (n=322, 28-29 weeks (n=336, and 30-32 weeks (803, and 14,721 creatinine assessments. The critical values determined in the training set (n=485 were 1.6, 1.1 and 1.0 mg/dL for each gestational age group, respectively. In the validation set (n=976, a serum creatinine level above the critical value was significantly associated with neonatal mortality (Odds ratio: 8.55 (95% confidence interval: 4.23-17.28; p<0.01 after adjusting for known renal failure risk factors, and with non-optimal neurodevelopmental outcome at two years (odds ratio: 2.06 (95% confidence interval: 1.26-3.36; p=0.004 before adjustment. Creatinine values greater than 1.6, 1.1 and 1.0 mg/dL respectively at 24-27, 28-29, 30-32 weeks of gestation were associated with mortality before and after adjustment for risk factors, and with non-optimal neurodevelopmental outcome, before adjustment.

    The clinical usefulness of serum free light chain (FLC) measurement in the management of patients with plasma cell proliferative disorders has been reported in several papers, and most clinical studies use the reference ranges declared by the manufacturer. The aim of the present study was to evaluate the reproducibility of FLCs immunoassay and to validate the reference range, before introducing it in routine setting. Internal quality control materials and a pool of fresh serum samples were used to evaluate imprecision; 162 fresh sera from healthy blood donors were analyzed to evaluate the reference range for FLCs. In order to verify the κ/λ FLC ratio, 43 sera from patients with polyclonal hypergammaglobulinemia were tested. The FLC immunoassay was performed using a nephelometer with the Freelite reagents. The imprecision studies performed using a serum pool tested with two different lots of reagents showed a mean CV of 16.09% for κFLC and of 16.72% for λFLC. Lower CV%s and different mean values were found by calculating the results from each specific lot separately, while different results were obtained using the control materials provided by the manufacturer. In reference subjects, the 2.5-97.5th percentiles were found to be 4.52-22.33 and 4.84-21.88mg/L for κFLC and λFLC, respectively. The range for κ/λ ratio (0.65-2.36) was validated with the values obtained from subjects with polyclonal hypergammaglobulinemia. In retesting 15 samples from blood donor subjects with a different lot of reagents, mean bias percentages of 17.60 for κFLC and 15.26 for λFLC were obtained. These findings confirm the lot-to-lot variability of the FLC assays also in the measurement of polyclonal light chains, as well as the need to carefully validate the reference values.

    The measurement of serum free light chain (sFLC) has been shown to be valuable in screening for the presence of plasma cell dyscrasia as well as for baseline prognosis in newly diagnosed patients. The aim of the present work was to study the prognostic value of sFLC in multiple myeloma in relation to other serum biomarkers, response to therapy and survival. Forty five newly diagnosed patients with MM were included in the study. Patients were divided into responders and non-responders groups according to response to therapy. sFLC and serum Amyloid A (SAA) were measured by immunonephelometry. The non-responders group showed a statistically significant higher kappa/lambda or lambda/kappa ratio and higher β2 microglobulin level, but lower albumin level at presentation, as compared to the responders group (P < 0.001). However, no statistically significant difference was detected between the two groups regarding SA A or calcium levels. Comparison between sFLC ratio obtained before and after therapy revealed significant decrease after treatment in the responders group (P = 0.05). Survival was significantly inferior in patients with an FLC ratio of ≥ 2.6 or ≤ 0.56 compared with those with an FLC ratio that was between 0.56 and 2.6 (P = 0.002).

    Carcinoembryonic Antigen is one of most frequently checked tumor markers in cancer management. We performed statistical analysis with serum CEA data of 2626 persons who received regular health examination and were thought to be free of active disease to determine the cutoff values of serum CEA level in normal Korean adults and to study the factors influencing serum CEA levels in normal subjects. 1) The cutoff values of serum CEA in normal Korean adults in general were 9.28 ng/ml for men, 5.90 ng/ml for women. 2) Serum CEA level was influenced by age, present smoking history, sex, and abnormal findings in chest X ray. 3) Serum CEA level had no correlation with the history of amount of alcohol consumption or obesity. 4) Cutoff values of serum CEA in normal Korean adults were tabulated according to age, sex, and smoking history. Serum CEA level was influenced by age, sex, present smoking history and abnormal findings in chest X ray and cutoff values of serum CEA were tabulated according to age, sex, and smoking history.

    Thioredoxin (Trx) is one of significant antioxidative molecules to diminish oxidative stress. Current evidence suggests that Trx is a potent antioxidant with cytoprotective functions. The aim of our study was to investigate specifically the association between serum Trx levels and acute ischemic stroke (AIS) patients. 198 AIS patients and 75 controls were enrolled to the study. Serum Trx levels were measured using an enzyme-linked immunosorbent assay (ELISA). Stroke severity was assessed with the National Institutes of Health Stroke Scale (NIHSS) score on admission. Clinical endpoint was functional outcome measured by Barthel Index (BI) 3 months after admission. Multivariate binary logistic regression analyses were performed to identify predictors. We found that serum Trx levels were significantly increased in patients as compared to controls. Serum Trx was an independent biomarker to predict ischemic stroke (OR, 1.264; 95% CI, 1.04-1.537; P = 0.019). In addition, there was a negative correlation between NIHSS score at admission and serum Trx levels in cardioembolic stroke patients (r = -0.422; P = 0.013). Furthermore, higher serum Trx levels in AIS patients were associated with favorable functional outcome. Serum Trx was an independent predictor for the functional outcome (OR, 0.862; 95% CI, 0.75-0.991; P = 0.037). Serum Trx might be as a biomarker of cardioembolic stroke severity. Increased serum Trx levels could be a useful tool to predict good prognosis in patients with AIS.

    The goal of this work was to determine if immediate versus postponed centrifugation of samples affects the levels of serum potassium. Twenty participants donated normal venous blood that was collected in four serum separator tubes per donor, each of which was analyzed at 0, 1, 2, or 4 hr on the Siemens Advia 1800 autoanalyzer. Coefficients of variation (CVs) for potassium levels ranged from 0% to 7.6% with a mean of 3 ± 2%. ANOVA testing of the means for all 20 samples showed a P-value of 0.72 (>0.05) indicating that there was no statistically significant difference between the means of the samples at the four time points. Sixteen samples were found to have CVs that were ≤5%. Two samples showed increases of potassium from the reference range to levels higher than the upper reference limit, one of which had a 4-hr value that was within the reference or normal range (3.5-5 mEq/l). Overall, most samples were found to have reproducible levels of serum potassium. Serum potassium levels from stored whole blood collected in serum separator tubes are, for the most part, stable at room temperature for at least 4 hr prior to analysis. However, some samples can exhibit significant fluctuations of values. © 2015 Wiley Periodicals, Inc.

    Objective: To investigate the clinical value of serum PSA and PAP determinations in diagnosis of prostate cancer patients. Methods: The serum PSA and PAP levels of 98 prostate cancer patients, 45 prostate benign disease patients and 40 normal subjects were tested by IRMA. Results: The serum PSA and PAP levels of prostate cancer patients were significantly higher than those in prostate benign disease patients and normal controls (P < 0.01). The diagnostic sensitivity and specificity of serum PSA for prostate cancer were 93.9% and 93.3% respectively. The diagnostic sensitivity and specificity of serum PAP for prostate cancer were 71.4% and 91.1% respectively. Conclusion: The determination of serum PSA and PAP was of high clinical value for diagnosis of early prostate cancer. It could be used as an important reference parameter for the clinical staging, follow-up of treatment result and prediction of prognosis

    This study investigates correlations between mother and infant Body Mass Index (BMI), their serum leptin values and breast milk leptin concentration in early infancy. We determined serum leptin values in 58 healthy infants and leptin values in their mothers' breast milk, using radioimmunoassay (RIA). Infant and maternal anthropometrics were measured. Median leptin concentration was 3.9 ng/mL (interquartile range (IQR): 2.75) in infant serum, 4.27 ng/mL (IQR: 5.62) in maternal serum and 0.89 ng/mL (IQR: 1.32) in breast milk. Median maternal BMI and weight were 24 kg/m² (IQR: 4.41) and 64 kg (IQR: 15). Median infant BMI was 15.80 kg/cm² (IQR: 4.02), while average weight was 5.130 kg (IQR: 1.627). Infants serum leptin values positively correlated with infants' BMI (p = 0.001; r = 0.213) and breast milk leptin (p = 0.03; r = 0.285). Maternal serum leptin values positively correlated with maternal BMI (p = 0.000, r = 0.449) and breast milk leptin ones (p = 0.026; r = 0.322). Breast milk leptin and maternal BMI could influence infant serum leptin values. Further studies are needed to better elucidate the role of genetics and environment on infant leptin production and risk of obesity later in life.

    Objective: To investigate the value of serum free light chain (FLC) in differential diagnosis of monoclonal gammopathy of renal significance (MGRS). Methods: Forty-nine hospitalized patients who underwent renal biopsy in Peking Union Medical College Hospital between January 2013 and December 2015 were included. Monoclonal gammopathy was detected by serum protein electrophoresis (SPE), serum immunofixation electrophoresis (IFE), urine IFE and serum FLC. All patients were classified as MGRS ( n =32) and monoclonal gammopathy of undetermined significance (MGUS) ( n =17). Results: Renal lesions in MGRS subgroup included light chain amyloidosis ( n =24, 75.0%), light chain deposition disease ( n =7, 21.9%), and fibrillary glomerulopathy ( n =1, 3.1%). Renal diseases in MGUS subgroup included membranous nephropathy ( n =10), focal segmental glomerulosclerosi (FSGS) ( n =3), diabetic glomerulopathy ( n =1), Henoch-Schonlein purpura nephritis ( n =1), anti-GBM disease concurrent with membranous nephropathy ( n =1) and glomerulomegaly ( n =1). Positive number of SPE, serum IFE, urine IFE and abnormal number of serum FLC ratio in MGRS subgroup were 12, 16, 23 and 30, respectively. Positive number of SPE, serum IFE, urine IFE and abnormal number of serum FLC ratio in MGUS subgroup were 11, 17, 6 and 3, respectively. MGRS and MGUS subgroups differed significantly in positive rate of serum IFE ( P value for MGRS, which was helpful for differential diagnosis of patients who had contraindication to renal biopsy.

    To determine the association of osteopenia with levels of serum 25-hydroxyvitamin D and HOMA-IR values in postmenopausal women. Methods One hundred healthy postmenopausal women were included in a cross-sectional study. Venous blood was collected after an overnight fast and 25-hydroxyvitamin D, glucose and insulin levels were measured. HOMA-IR was calculated. Bone mineral density was measured with a dual X-ray absorptiometer. There was no difference in serum 25-hydroxyvitamin D levels and HOMA-IR values between the two groups. A weak positive correlation between serum 25-hydroxyvitamin D levels and osteopenia was detected. Insulin resistance had a weak negative association with osteopenia. The correlations between osteopenia and serum 25-hydroxyvitamin D levels and HOMA-IR values were weak among early postmenopausal women.

    To study the clinical value of serum vitamin B 12 and folate in cerebrovascular disease, the concentration of serum vitamin B 12 and folate in 32 patients with cerebrovascular disease was measured by radioimmunoassay. The results showed that the changes in folate in all groups were not significant. The content of vitamin B 12 in multi-infarct dementia was markedly lower than that in cerebral infarction and cerebral hemorrhage. Moreover, the level of vitamin B 12 was lower in paralytic patients with muscular strength of grade 0-III. It can be concluded that serum vitamin B 12 level had association with intelligent disorder and paralytic degree

    Measurement of the mass concentration of serum enzymes by radioimmunoassay provides direct quantitation of specific isoenzymes and may be less subject to some of the limitations of traditional assay procedures for enzymes. We describe the development of a sensitive and specific radioimmunoassay for the muscle isoenzyme of creatine kinase, CK-MM, in human serum. CK-MM, purified from human skeletal muscle, was used to raise high-titer antisera and for iodination by the Chloramine T method. The radioimmunoassay required 50 μl of sample, utilized a double-antibody separation method, and was completed in 24 h. Cross reactivity with CK-BB was virtually zero, 3 to 17 percent with CK-MB. The mass concentration of CK-MM in the serum of healthy subjects ranged from 36 to 1668 μg/liter and correlated closely with total CK enzymatic activity. Serum concentrations of CK-MM from casually selected patients correlated less well with total CK enzymatic activity, suggesting the existence of other CK isoenzymes or the presence of inactive forms

    Objective: To determine the concentration of C-reactive protein in pre- and post-operative serum samples of brain tumour patients in order to detect the potential risks of post-operative infections. Methods: Serum C-reactive protein was measured on pre- and post-operative Day 1, Day 2 and Day 7 in 18 patients who underwent surgery for brain tumours. The study was performed at the Neurosurgical Ward, Jinnah Postgraduate Medical Centre, Karachi, from May 2007 to April 2008. Mean pre-operative patients and control values were compared using Mann-Whitney or Wilcoxon tests for comparing between pre- and post-operative values. P-value was considered significant at 5.0mg/L but no statistically significant difference was found when compared with healthy controls, with mean 4.4+-6.6 and 0.9+-0.7, respectively. Significantly raised serum concentrations were observed in all post-operative samples when compared with pre-operative samples. Serum CRP concentrations significantly increased post-operatively on Day 1, with mean value of 102.9+-82.0mg/L (p<0.0005), and further increased on Day 2 with mean value of 166.9+-128.1mg/L (p<0.0005), but declined on Day 7, with mean value of 42.7+-63.6mg/L (p<0.005). Conclusion: Pre-operative serum C-reactive protein concentrations of 28% of the patients were elevated, suggesting an association with brain tumours. Post-operative serum concentrations were significantly higher than those noted before the surgery. Absence of a fall of concentration from peak value on post-operative Day 2 or a secondary rise from post-operative Day 7 could be alarming for inter-current infection. (author)

    Diagnosis of tuberculosis (TB) is not always easy, thus employing methods with a short duration and acceptable sensitivity and specificity is necessary to diagnose TB. The aim of this study was to investigate the diagnostic value of serum adenosine deaminase (ADA) level for diagnosis of pulmonary tuberculosis. A total of 160 sex and age-matched subjects were included in this study, and were divided to four groups; forty patients with pulmonary tuberculosis (PTB) diagnosed based on the national TB program (NTP), forty patients with non-tuberculosis bacterial pneumonia, forty patients with lung cancer and forty people who were healthy in every respect. Serum adenosine deaminase activity in patients of each group was measured by the Giusti and Galanti calorimetry method using a commercial kit (Diazyme, USA). The ANOVA analysis was used to compare groups for quantitative variables. Mean serum ADA level in the PTB group was clearly higher than the mean serum ADA in the other three groups. Mean serum ADA was 26 IU/L in PTB patients, 19.48 IU/L in patients with pneumonia, 15.8 IU/L in patients with lung cancer, and 10.7 IU/L in the control group (P ADA in patients with PTB sensitivity and specificity was defined as 35% and 91%, respectively. Serum ADA activity with high specificity percentage may be a useful alternative test in restricted resource areas to rule out diagnosis of PTB. However, serum ADA activity is not a useful tool for TB diagnosis.

    This study was planned to investigate whether serum α-amylase concentration may be associated with running performance, physiological characteristics and other clinical chemistry analytes in a large sample of recreational athletes undergoing distance running. Forty-three amateur runners successfully concluded a 21.1 km half-marathon at 75%-85% of their maximal oxygen uptake (VO2max). Blood was drawn during warm up and 15 min after conclusion of the run. After correction for body weight change, significant post-run increases were observed for serum values of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, bilirubin, creatine kinase (CK), iron, lactate dehydrogenase (LDH), triglycerides, urea and uric acid, whereas the values of body weight, glomerular filtration rate, total and low density lipoprotein-cholesterol were significantly decreased. The concentration of serum α-amylase was unchanged. In univariate analysis, significant associations with running performance were found for gender, VO2max, training regimen and pre-run serum values of α-amylase, CK, glucose, high density lipoprotein-cholesterol, LDH, urea and uric acid. In multivariate analysis, only VO2max (p=0.042) and baseline α-amylase (p=0.021) remained significant predictors of running performance. The combination of these two variables predicted 71% of variance in running performance. The baseline concentration of serum α-amylase was positively correlated with variation of serum glucose during the trial (r=0.345; p=0.025) and negatively with capillary blood lactate at the end of the run (r=-0.352; p=0.021). We showed that the baseline serum α-amylase concentration significantly and independently predicts distance running performance in recreational runners.

    As a noninvasive marker, serum alanine aminotransferase (ALT) has limitations, because a large proportion of patients chronically infected with hepatitis B virus (HBV) suffer from severe hepatic necroinflammation, but have normal or mildly elevated ALT. In the present study, we aimed to investigate the potential value of serum Golgi protein 73 (GP73) in predicting significant hepatic necroinflamation among chronic HBV infected patients. A cohort of 497 chronic HBV infected patients was retrospectively recruited. Liver biopsy was performed in all patients and serum GP73 levels were measured by enzyme-linked immunosorbent assay. Serum GP73 increased in parallel with the increase in hepatic necroinflammatory activity grade (r = 0.682) and the stage of liver fibrosis (r = 0.539). The positive correlation of serum GP73 with the degree of hepatic necroinflammatory activity was statistically significant, while serum GP73 with the stage of liver fibrosis was weaker than that with hepatic necroinflammation. Furthermore, serum GP73 levels were significantly greater in patients with normal or mildly elevated ALT and significant hepatic necroinflammation (≥G2) than in patients with minimal to mild hepatic necroinflammation. The sensitivity and specificity of GP73 for the diagnosis of G2 hepatic necroinflammation was 42.35% and 95.0%, respectively, at a cut-off value of 88.38 ng/mL. When the cut-off value was set at 124.76 ng/mL, the sensitivity and specificity of GP73 for the diagnosis of G3 hepatic necroinflammation was 55.56% and 97.29%, respectively. These findings indicate that GP73 holds promise as an important candidate for diagnosing significant hepatic necroinflammation. © 2018 Wiley Periodicals, Inc.

    High serum day 3 FSH levels are associated with poor ovarian reserve and reduced fertility, but the interpretation of FSH values according to age is still not univocal. The purpose of this study was to determine age-dependent reference values in women with regular menstrual cycles and FSH as a guide for specialists. The study was performed at the Department of Mother-Infant of a University-based tertiary care centre. One-hundred ninety-two healthy normal menstruating women were recruited for the study. All patients attended the department on menstrual cycle day 3 for a blood sample for FSH and estradiol determination. A linear relationship between FSH or estradiol serum levels and age was observed. The FSH level increased by 0.11 IU for every year of age (1 IU for every 9 years of age). The values of FSH and estradiol corresponding to the 5th, 25th, 50th, 75th, 95th centiles for any specific age have been calculated. Serum FSH levels need to be interpreted according to age-dependent reference values. Serum FSH levels on 95th centile for any age may represent a warning sign for reduced ovarian reserve.

    Since increased synthesis of collagen has been demonstrated in tissue of type IV gastric cancer, we attempted to distinguish type IV gastric cancer from other cancers by measuring serum levels of type III procollagen N-terminal peptide (type III-N-peptide). Mean serum levels in type IV gastric cancer patients without metastasis were found to be elevated above normal values and developed a tendency to be higher than those in types I, II and III gastric cancer patients without metastasis. Highly positive ratios were found in patients with liver diseases including hepatoma and colon cancer, biliary tract cancer, and esophageal cancer patients with liver, lung or bone metastasis, but only 2 out of 14 of these cancer patients without such metastasis showed positive serum levels of type III-N-peptide. Positive cases in patients with type IV gastric cancer were obtained not only in the group with clinical stage IV but also in the groups with clinical stages II and III. In addition, high serum levels of type III-N-peptide in patients with type IV gastric cancer were seen not only in the cases with liver, lung or bone metastasis but also in cases with disseminated peritoneal metastasis alone. These results suggest that if the serum level of type III-N-peptide is elevated above normal values, type IV gastric cancer should be suspected after ruling out liver diseases, myelofibrosis and liver, lung or bone metastasis.

    Full Text Available C-reactive protein (CRP has previously been shown to serve as a prognostic parameter in women with gynecologic malignancies. Due to the lack of valid prognostic markers for uterine leiomyosarcoma (ULMS this study set out to investigate the value of pre-treatment CRP serum levels as prognostic parameter.Data of women with ULMS were extracted from databases of three Austrian centres for gynaecologic oncology. Pre-treatment CRP serum levels were measured and correlated with clinico-pathological parameters. Univariate and multivariable survival analyses were performed.In total, 53 patients with ULMS were included into the analysis. Mean (SD CRP serum level was 3.46 mg/dL (3.96. Solely, an association between pre-treatment CRP serum levels and tumor size (p = 0.04 but no other clinic-pathologic parameter such as tumor stage (p = 0.16, or histological grade (p = 0.07, was observed. Univariate and multivariable survival analyses revealed that CRP serum levels (HR 2.7 [1.1-7.2], p = 0.037 and tumor stage (HR 6.1 [1.9-19.5], p = 0.002 were the only independent prognostic factors for overall survival (OS in patients with ULMS. Patients with high pre-treatment CRP serum levels showed impaired OS compared to women with low levels (5-year-OS rates: 22.6% and 52.3%, p = 0.007.High pre-treatment CRP serum levels were independently associated with impaired prognosis in women with ULMS and might serve as a prognostic parameter in these patients.

    Objective: To explore the value of serum thyrotrophin receptor antibody (TRAb) on the pathological mechanism of Graves ophthalmopathy. Methods: Two hundred and nineteen newly diagnosed Graves disease patients who were divided into Graves ophthalmopathy group (n=121) and without Graves ophthalmopathy group (n=98) were tested serum concentration with thyroid function, thyroperoxidase antibodies (TPOAb), thyroglobulin antibodies (TgAb) and TRAb. According to the consensus statement of the European Group on Graves ophthalmopathy, clinical activity score (CAS) and severity evaluation were carried out on Graves ophthalmopathy patients. Results: There was no significant difference in serum concentration of free thyroxine (FT 4 ), free triiodothyronine (FT 3 ), TPOAb and TRAb between the Graves ophthalmopathy group and the without Graves ophthalmopathy group. Serum concentration of TRAb was not correlated with the severity and CAS of Graves ophthalmopathy. Conclusions: The CAS and the severity of Graves ophthalmopathy were irrelevant to the serum concentration of TRAb. Therefore, the correlation between TRAb and Graves ophthalmopathy still needs further study. (authors)

    Objective: To investigate the clinical value of peri-interventional procedure serum bile acid (TBA) detection in patients with primary liver cancer. Methods: The serum TBA was examined peri-operatively in 160 patients with primary liver cancer for testing the correlations between TBA, liver function, the degree of hepatocirrhosis, interventional therapy method and hepatic failure. Results: The preoperative mean value of serum TBA increased significantly in comparing with that of the control group (P<0.01). The preoperative value of serum TBA in different Child grading patients with primary liver cancer were different significantly (P<0.01), Child A< Child B< Child C, the increased degree of serum TBA corresponded with Child grading of the liver function and the cirrhotic degree of liver. In patients with liver function of Child B and C, the postoperative mean values of serum TBA in different interventional therapy methods were different significantly (P<0.01). Comparing with that of the patients without hepatic failure, the postoperative value of serum TBA in the patients with hepatic failure increased significantly (P<0.01). Conclusions: The value of serum TBA can sensitively and accurately reflect liver reserve ability and damage degree of peri-interventional procedure liver function. Hepatic failure can be detected in time and the prognosis of the patients with primary liver cancer can be predicted by testing the value of serum TBA continually. (authors)

    The giant panda ( Ailuropoda melanoleuca) is a high-profile threatened species with individuals in captivity worldwide. As a result of advances in captive animal management and veterinary medicine, the ex situ giant panda population is aging, and improved understanding of age-related changes is necessary. Urine and blood samples were collected in April and July 2015 and analyzed for complete blood count, serum biochemistry, and biochemical and microscopic urine analysis for all individuals sampled ( n = 7, 7-16 yr of age) from giant panda housed at the China Research and Conservation Centre for the Giant Panda in Bifengxia, Sichuan Province, China. Hematology and serum biochemistry values were similar to those previously reported for giant panda aged 2-20 yr and to Species360 (formerly International Species Information System) values. Urine was overall dilute (urine specific gravity range: 1.001-1.021), acellular, and acidic (pH range: 6-7). This is the first report of hematologic and serum biochemistry, with associated urinalysis values, in the giant panda aged 7-16 yr.

    The role of wildlife in the epidemiology of leishmaniosis in under debate, and determining whether infection with Leishmania infantum causes illness in wild carnivores is important to determine its potential role as a reservoir. To provide for the first time serum biochemistry reference values for the common genet (Genetta genetta), and to determine variations associated with L. infantum infection. Twenty-five serum biochemistry parameters were determined in 22 wild-caught genets. Blood samples were analyzed for L. infantum DNA by means of real-time polymerase chain reaction (PCR). Two female genets were positive for L. infantum DNA but did not show any external clinical sign upon physical examination. Among other variations in the biochemistry values of these genets, one presented a higher concentration of gamma-globulins and cholesterol, whereas the other genet presented increased creatinine, bilirubin, and chloride levels when compared to uninfected females. Sex-related differences in some parameters were also reported. Infection with L. infantum may sometimes be accompanied by abnormal serum biochemistry in wild carnivores. Clinical disease may occur in L. infantum-infected wild carnivores. This has implications in the epidemiology of leishmaniosis. In addition, the data provided here would also be useful as reference values for researchers or rehabilitators working with the common genet.

    Strong and weak points of both the Phadebas B/sub 12/ test kit by Pharmacia Co. Ltd. and the CIS B/sub 12/ kit by CEA Co. Ltd. were examined to determine and evaluated. One strong point was that both of kits were comparatively easy to operate. Another was that they were very accurate if only one pipet was used and it was correctly handled. The error from the fractional infusion of 0.1 ml of /sup 57/Co-B/sub 12/ sample remained within +-1.8%, including the error of measuring radioactivity. The recovery rate of vitamin B/sub 12/ added to the serum was 100+-10%. Close correlation was found between the serum B/sub 12/ values measured by each kit and with a careful procedure almost accurate, highly reproducible values were obtained. It was necessary to further examine the pH of the buffer solution in the Phadebas kit and the conditions of extraction of B/sub 12/ from the serum in the CIS kit. In reading the B/sub 12/ values from the standard curve, it was preferable to perform a logic change B/B/sub 0/ % in the samples and to make a linear standard curve, so that the accuracy of the reading would not be infuluenced by variations in the data.

    Full Text Available In northern Brazil, the seasons are not well defined compared to the South and Southeast regions, due to a hot and humid equatorial climate with a rainy season, known as the Amazonian winter, and a period with less rain, known as the Amazonian summer. The goal of this study was to evaluate the biochemical variation of serum from the Amazon Boa constrictor by correlating the values with the seasons of the region. A biochemical analysis of the serum was performed (AST, ALT, LDH, ALP, calcium, uric acid, phosphorus, total protein, albumin and globulin using 31 individuals of Boa constrictor constrictor, which were kept in captivity. It was observed that eight of the ten parameters were higher in the winter compared to the summer (total protein, albumin, globulin, ALT, AST, ALP, LDH and calcium. The ALT, AST and calcium values had statistically significant differences for the summer and winter, while the other parameters appear to be influenced by seasonality. This was the first study of snakes kept in captivity that analyzed the serum chemistry profile of Boa constrictor constrictor from the state of Pará, Brazil.

    Full Text Available ObjectiveTo explore the early diagnostic values of serum alpha-fetoprotein (AFP, gamma-glutamyltransferase Ⅱ (GGTⅡ, and Golgi protein 73 (GP73 in patients with primary hepatocellular carcinoma (PHC. MethodsThe serum specimens of 100 patients with liver diseases (50 cases of hepatitis and liver cirrhosis and 50 cases of PHC and 50 healthy people were collected in our hospital from February 2013 to February 2014. Electrochemical luminescence technique, specific immuno-membrane adsorption assay, and enzyme-linked immunosorbent assay were used to measure the serum levels of AFP, GGTⅡ, and GP73. Comparison of continuous data between multiple groups was made by analysis of variance, and comparison between two groups was made by q test. The receiver operating characteristic (ROC curves of single or combined test results were made, and the areas under the ROC curves (AUCs were calculated. The sensitivity, specificity, and AUCs of AFP, GGTⅡ, GP73, and the combined test were analyzed and compared. ResultsThe level of serum GGTⅡ in the PHC group was significantly different compared with those in the other two groups (F=16.224, P<0.05, but there was no significant difference between the normal group and the hepatitis and liver cirrhosis group (P>0.05. Significant differences in serum levels of AFP and GP73 were observed by paired comparison between the PHC group, hepatitis and liver cirrhosis group, and normal group (F=193.128, F=20.231, P<0.05 for both. When assayed alone, the specificities of GP73, GGTⅡ, and AFP were 69%, 64% and 51%, respectively, and the sensitivities were 92%, 84%, and 76%, respectively. In combined test, the specificity was 94.6% and the sensitivity was 98.8%. ConclusionThe GP73 test is the best performer in the single assays. Combined test of serum AFP, GGTⅡ, and GP73 shows a good diagnostic value for PHC with greatly improved specificity and sensitivity.

    Full Text Available The growing incidence of prostate cancer (PC and its variable nature are an important problem today. PC is distinguished by its latent ability in many cases, which makes its screening difficult.Prostate-specific antigen (PSA is one of the most common tumor markers of PC, which are used for mass male screening. However, the detection rate of PC in men with normal PSA values is also very high. This promotes an active search for new markers and predictors of PC.The effect of androgens on hormonal carcinogenesis in the prostate suggests that the analysis of serum testosterone concentrations and free androgen index may be made in patients with low PSA levels in the early diagnosis and prognosis of PC.

    Well-validated reference values are necessary for a correct interpretation of a serum PTH concentration. Establishing PTH reference values needs recruiting a large reference population. Exclusion criteria for this population can be defined as any situation possibly inducing an increase or a decrease in PTH concentration. As recommended in the recent guidelines on the diagnosis and management of asymptomatic primary hyperparathyroidism, PTH reference values should be established in vitamin D-replete subjects with a normal renal function with possible stratification according to various factors such as age, gender, menopausal status, body mass index, and race. A consensus about analytical/pre-analytical aspects of PTH measurement is also needed with special emphasis on the nature of the sample (plasma or serum), the time and the fasting/non-fasting status of the blood sample. Our opinion is that blood sample for PTH measurement should be obtained in the morning after an overnight fast. Furthermore, despite longer stability of the PTH molecule in EDTA plasma, we prefer serum as it allows to measure calcium, a prerequisite for a correct interpretation of a PTH concentration, on the same sample. Once a consensus is reached, we believe an important international multicentre work should be performed to recruit a very extensive reference population of apparently healthy vitamin D-replete subjects with a normal renal function in order to establish the PTH normative data. Due to the huge inter-method variability in PTH measurement, a sufficient quantity of blood sample should be obtained to allow measurement with as many PTH kits as possible.

    Objective: To investigate the clinical diagnostic value of serum TRAb levels determination in patients with Graves' disease. Methods: Serum TRAb (with RRA), FT 3 , FT 4 , TSH (with CLIA) levels were measured in 223 patients with Graves' disease both before and 6, 12, 36 months after treatment with antithyroid drugs (ATD) as well as in 50 controls. Results: Positive rate of serum TRAb was 93.3% in patients with Graves' disease before treatment. Six months after ATD therapy the positive rate dropped to 41.3%, being still significantly higher than that in controls (P<0.05). The TRAb positive rate dropped steadily with 12 (18.3% ), 24 (8.9% ) and 36 months (4.9%) of ATD treatment. In the 21 patients who had hyperthyroidism recurred after the course of treatment, TRAb remained positive in 18 of them (80.7%). Conclusion: Persistent positive TRAb despite euthyroid status in patients with Graves' disease after seemingly successful ATD treatment donates persistent immunodysfunction and possible recurrence. It is mandatory to continue ATD treatment until TRAb negative. (authors)

    To explore the value of combined detection of serum β-HCG and P in diagnosis of early ectopic pregnancy and expectant therapeutic efficacy. Serum levels of β-HCG and P of 324 patients with early ectopic pregnancy and 146 normal early pregnant women were determined and compared by RIA, Serum β-HCG and P were compared between before and after treatment. The required time when serum β-HCG and P decreased to the normal rang of the patients treated successfully were observed respectively. The results showed that the serum β-HCG and P value in ectopic pregnancy group were significantly lower than those in intrauterine gestation group (P<0.05). The variation of P was significant between success and failure groups of drug conservative treatment, but β-HCG had no significant difference. The required time when serum P decreased to the normal was significantly less than the serum β-HCG dropped to normal. Combined detection of serum levels of β-HCG and P is an adjunctive method to diagnose early ectopic pregnancy, so it giants opportunity for treatment of early ectopic pregnancy and is of positive clinical application value for observation therapeutic effect and prognosis of the disease. P values may be one of the more important reference index to predict whether conservative treatment is successful or not than β-HCG. (authors)

    Ferritin reference values vary by age, gender, and ethnicity. We aimed to determine reference values of serum ferritin (SF) and the percentage of transferrin saturation (TSAT) for Korean children and adolescents. We analyzed data from 2,487 participants (1,311 males and 1,176 females) aged 10-20 years from the Korea National Health and Nutrition Examination Survey (2010-2012). We calculated age- and gender-stratified means and percentile values for SF and TSAT. We first plotted mean SF and TSAT by gender and according to age. In males, mean SF tended to be relatively constant among participants aged 10 to 14 years, with an upward trend thereafter. Mean SF trended downward among female participants until the age of 15 years and remained constant thereafter. Thus, significant gender differences in ferritin exist from the age of 14 years. High levels of SF were associated with obesity, and lower SF levels were associated with anemia and menarche status. We established reference values of SF and TSAT according to age and gender. The reference values for SF calculated in this study can be used to test the association between SF values and other defined diseases in Korean children and adolescents.

    Objective: To compare the diagnostic value of tissue polypeptide specific antigen (TPS) in serum, with the carbohydrate antigens (CA) 19-9, CA50, CA125 and CA242 in pancreatic carcinoma. Methods: Serum TPS was measured with enzyme linked immunosorbent assay (ELISA). CA19-9 and CA125 were measured with chemiluminescent immunoassay. CAS0 and CA242 were measured with immunoradiometric assay in 33 patients with pancreatitis, 34 patients with pathologically proven pancreatic carcinoma, and 35 patients with non-pancreatic malignancies. Statistic analysis was carried out with SPSS 9.0 software. Results: Patients with pancreatic carcinoma had relatively higher levels of TPS [(386.5 ± 315. 1) U/L] and CA19-9 [(10 820.9 ± 389.7) kU/L] when compared with patients with pancreatitis [(86. 2 ± 28.1) U/L and (61.5 ± 24.7) kU/L, respectively; F = 936. 42, P < 0. 001 ; F = 2217. 09, P < 0. 001], with a sensitivity and a specificity of 70.6% (48/68) and 57.4% (39/68), respectively, for TPS, and 82.4% (28/34) and 77.9% (53/68), respectively, for CA19-9. Diagnostic performance was further improved when TPS was assayed in combination with CA19-9, CA50, CA125 and CA242. Conclusion: Serum TPS has an incremental value in complementing CA19-9 in the diagnosis of pancreatic carcinoma. (authors)

    Objective: To explore the expression and the clinical diagnostic value of serum miR-21 for invasive pulmonary aspergillosis (IPA). Methods: Outpatients and inpatients from the Fourth Affiliated Hospital of Guangxi Medical University were included in the study during June 2014 to September 2015. The IPA group had 40 patients, male 22, female 18, aged 55-68 years (mean 60 ), while the control groups included 50 patients with pulmonary tuberculosis [male 23, female 27, aged 50-62 years (mean 55 )], 50 patients with lung cancer [male 30, female 20, aged 55-70 years (mean 62)], and 50 healthy controls [male 25, female 25, aged 50-67 years (mean 60) ]. Serum were obtained and the levels of miR-21 and galactomannan (GM test) and (1, 3)-beta-D-glucan (G test) were measured. The related indexes were analyzed by logistic regression and ROC curves. Results: The serum miR-21 expression in IPA and lung cancer patients were increased, the median values ( P (25) and P (75)) being 0.42(0.31, 0.62)and 0.80(0.65, 0.94) respectively, both of which were significantly higher than those of the healthy controls [ 0.09(0.04, 0.15)] and the tuberculosis cases [ 0.08(0.03, 0.16)], P tuberculosis cases and lung cancer cases were 0.914, 0.897 and 0.863 respectively, with the Youden index being 0.780, 0.700 and 0.605 respectively. The serum levels of miR-21 in between 0.198 and 0.723 had preferable diagnostic accuracy. ROC analysis for miR-21 in IPA compared to healthy controls showed that the AUCs of miR-21 combined with G test or GM test were 0.992 and 0.966 respectively, the sensitivity being 95% (38/40) and 93% (37/40) respectively, the specificity being 98% (49/50) and 96% (48/50) respectively, and the Youden index being 0.930 and 0.885 respectively. If miR-21 was combined with G test and GM test, the AUC was 0.994, the sensitivity and the specificity being 98% (38/40) and 96% (48/50) respectively, and the Youden index increased to 0.935.

Study 1: 168 patients presenting between gestational weeks 6 and 12 with: extrauterine pregnancy, 29; missed abortion, 50; incomplete spontaneous abortion, 38; imminent abortion, 33; and normal pregnancy (no history of endometriosis or ovarian mass), 18. Study 2: Fifty consecutive patients with vaginal bleeding during gestational weeks 6-12 all of whom having demostrable fetal heartbeat. Eighteen patients finally aborted whereas the remainder had normally continuing pregnancy until term. Study 1: Single serum determinations of CA 125 and beta-hCG were correlated with the different disorders observed. Study 2: Two sequential measurements of serum CA 125 and beta-hCG performed within a 5-7 days interval were related to the outcome of pregnancy as indicated by changes of the ultrasound presentation, miscarriage, future hospitalization, or delivery. Study 1: Patients with vaginal bleeding generally had higher median CA 125 values (38 IU/ml; range 1.3-540) compared to non-bleeding patients (17.8 IU/ml; range 1.0-157). No statistically significant differences in regard to median serum CA 125 levels between symptomatic and normal pregnancies occurred: normal pregnancy, 25.5 IU/ml (range 3.2-97); ectopic pregnancy, 26 IU/ml (range 1.3-157); missed abortion, 19.1IU/ml (range 1-242); threatened abortion, 48 IU/ml (range 5.2-540); spontaneous abortion, 40 IU/ml (range 5.4-442). Study 2: Initial CA 125 levels did not differ significantly between both groups of patients with 27/32 non-aborters and 13/18 aborters showing concentrations below 65 IU/ml. After 5-7 days, CA

    Full Text Available Thai indigenous chickens (Gallus domesticus have been domesticated in rural villages in Thailand for a long time. These birds are important to low-income people who live in the rural part of Thailand. However, health problems have been a major cause limiting their population. Hematological, electrolyte and serum biochemical values, which are important for diagnosis of clinical signs and symptoms when affected by diseases, are limited. Blood samples from 40 chickens (20 males and 20 females were used for hematological test while another 18 samples (from 10 males and 8 females were analysed for electrolyte and serum biochemical values. The samples were obtained from Khon Kaen, Kalasin, Roi - Et, Maha Sarakham and Nakhon Ratchasima provinces, northeastern region of Thailand. The results revealed the following information: total red blood cell count, hemoglobin concentration, packed cell volume, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, total white blood cell count, lymphocyte, heterophil, monocyte, eosinophil, basophil, H:L ratio values of Thai native chickens were 2.26 ± 0.29 × 106 cells/μl, 8.89 ± 1.20 g/dl, 32.18 ± 4.46%, 144.63 ± 18.61 fl, 39.69 ± 4.96 pg, 27.86 ± 3.37 g/dl, 2.04 ± 0.45 × 104 cells/μl, 63.68 ± 9.36%, 23.70 ± 7.21%, 4.20 ± 3.20%, 5.83 ± 3.53%, 2.65 ± 2.09% and 0.40 ± 0.17, respectively. Potassium, sodium and chloride values of Thai native chickens were 5.3 ± 0.8 mmol/l, 155.9 ± 3.1 mmol/l and 116.9 ± 2.7 mmol/l, respectively. Furthermore, serum biochemistry values of Thai native chickens such as total protein, glucose, alkaline phosphatase, uric acid, calcium and cholesterol were 4.6 ± 1.0 mg/dl, 190.2 ± 29.8 mg/dl, 235.9 ± 68.6 U/L, 5.0 ± 1.9 mg/dl, 10.4 ± 1.2 mg/dl and 102.4 ± 30.8 mg/dl, respectively.

    Adipokines are biologically active, low-molecular weight peptides, which play a major role in metabolic homeostasis in humans. Leptin has gained increasing attention in pediatrics as a biomarker for various metabolic pathologies. Yet, its usefulness is hampered by the relative lack of reference values from pediatric settings. Accordingly, this study aims to evaluate serum concentrations of leptin, soluble leptin receptor (sOB-R), and free leptin index (FLI) in healthy Danish schoolchildren aged 6-18 years and subsequently to establish reference intervals across sex and age groups. A total of 1193 healthy, non-obese Danish schoolchildren (730 girls, 463 boys) aged 6-18 years (median 11.9) were examined by trained medical staff. Serum leptin and sOB-R concentrations in venous fasting blood samples were quantitated by immunoassay. Percentile curves of leptin, sOB-R, and free leptin index were calculated using the General Additive Model for Location Scale and Shape (GAMLSS). Significant age and sex-dependent differences in circulating leptin levels were found. In boys, the median leptin concentration for all ages combined was 3.35 μg/L (95%-interval: 0.71-22.47) and in girls, it was 9.89 ng/L (95%-interval: 2.06-41.49). For SOB-R, no sex-specific difference was found, and the median sOB-R concentration was 8.24 μg/L (IQR: 3.58-23.74; range: < 1.56-744.15). We demonstrated an age-dependent correlation with both serum leptin concentration and free leptin index with a gradual and significant increase in girls throughout childhood and adolescence and a significantly higher leptin concentration and free leptin index bell-shaped peak in early adolescence in boys.

    Serum BEI determinations were performed on 249 fifteen year old exposed and nonexposed apparently normal children all of whom were in utero at the time of the atomic bombing in Nagasaki, Japan. The girls were more mature in growth and development than the boys; the boys were probably near the peak stress of adolescent development. No statistically significant difference of BEI values was found between exposed and control groups. The trimester of gestation of the children at the time of exposure appeared to have no conclusive effect on the BEI value, but the number of subjects from each trimester was too small for satisfactory statistical analysis. Eleven females with goiter were analyzed separately. There was a slight preponderance of goiter in the exposed group, but the difference was not significant. The mean BEI value for the males was significantly lower than that for the females. The mean BEI values for Japanese adolescents are higher than for adolescents in the Middle Atlantic and New England states in the United States. 31 references, 2 tables.

Serum PCT was measured for all patients, and the white blood cell count (WBC and high-sensitivity C-reactive protein (hsCRP were measured for patients with liver failure. The clinical manifestations were observed and recorded. The t test was used for comparison of normally distributed continuous data, while the Kruskal-Wallis H test was used for non-normally distributed continuous data; the Mann-Whitney U test was used for pairwise comparison of continuous data. The chi-square test was used for comparison of categorical data. The receiver operating characteristic (ROC curve was used for the analysis of predictive value. ResultsThe liver failure group had a significantly higher PCT level than the severe liver injury group, moderate liver injury group, and mild liver injury group (0.81[0.34-2.15] vs 0.53[0.21-1.59], 0.35[010-1.18], and 0.17[0.10-0.60], χ2=25.091, P<0.05. The liver failure patients with PCT levels of <0.25 ng/ml (n=10, 0.25-0.5 ng/ml (n=10, and >0.5 ng/ml (n=48 had infection rates of 20%, 30%, and 66.7%, respectively, with a significant difference between the patients with a PCT level of >0.5 ng/ml and those with PCT levels of <0.25 ng/ml and 0.25-0.5 ng/ml (χ2=5631,4650,P=0018,0031. Among the liver failure patients, the infection cases had significantly higher PCT, WBC, and hsCRP than the non-infection cases (PCT: 3.72±1.33 ng/ml vs 0.34±0.12 ng/ml, t=-2.547, P=0.015; hsCRP: 16.70±7.03 mg

    We aimed to assess the predictive value of mean serum uric acid (SUA) levels for incident prediabetes. Normoglycemic adults (n=39,353) were followed for a median of 3.0years. Prediabetes is defined as impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or impaired HbA1c (IA1c), based on the American Diabetes Association criteria. Serum SUA levels were measured annually. Four diagnostic strategies were used to detect prediabetes in four separate analyses (Analysis 1: IFG. Analysis 2: IFG+IGT. Analysis 3: IFG+IA1c. Analysis 4: IFG+IGT+IA1c). Cox proportional hazards regression models were used to assess the relationship between SUA quintiles and prediabetes. C-statistic was additionally used in the final analysis to assess the accuracy of predictions based upon baseline SUA and mean SUA, respectively. After adjustment for potential confounders, the hazard ratios (95% confidence interval) of prediabetes for the highest versus lowest quintile of mean SUA were 1.22 (1.10, 1.36) in analysis 1; 1.59 (1.23, 2.05) in analysis 2; 1.62 (1.34, 1.95) in analysis 3 and 1.67 (1.31, 2.13) in analysis 4. In contrast, for baseline SUA, significance was only reached in analyses 3 and 4. Moreover, compared with baseline SUA, mean SUA value was associated with a significant increase in the C-statistic (Pprediabetes risk, and showed better predictive ability for prediabetes than baseline SUA.

    The International Myeloma Working Group recommendations for monitoring disease progression or response include quantitation of the involved monoclonal immunoglobulin. They have defined the minimum change criteria of ≧25% with an absolute change of no gel-based serum protein electrophoresis. Sixteen clinically stable MGUS patients were identified from our clinical hematology database. Individual biological variability (CVi) was determined and used to calculate a monoclonal protein reference change value (RCV). Analytical variability of the normal protein fractions (albumin, alpha-1, alpha-2, beta, total gamma) ranged from 1.3% for albumin to 5.8% for the alpha-1 globulins. CVa of low (5.6g/L) and high (32.2g/L) concentration monoclonal proteins were 3.1% and 22.2%, respectively. Individual CVi of stable patients ranged from 3.5% to 24.5% with a CVi of 12.9%. The reference change value (RCV) at a 95% probability was determined to be 36.7% (low) 39.6% (high) using our CVa and CVi. Serial monitoring of monoclonal protein concentration is important for MGUS and multiple myeloma patients. Accurate criteria for interpreting a change in monoclonal protein concentration are required for appropriate decision making. We used QC results and real-world conditions to assess imprecision of serum protein fractions including low and high monoclonal protein fractions and clinically stable MGUS patients to determine CVi and RCV. The calculated RCVs of 36.7% (low) and 39.6% (high) in this study were greater that reported previously and greater than the established criteria for relapse. Response criteria may be reassessed to increase sensitivity and specificity for detection of response. Copyright © 2017 The Canadian Society of Clinical Chemists. Published by Elsevier Inc.

    Full Text Available Introduction: N-methyl-D-aspartate receptor subunits antibody (NR2-ab is a sensitive marker of ischemic brain damage in clinical circumstances, such as cerebrovascular accidents. We aimed to assess the value of serum NR2-ab in predicting the post-cardiopulmonary resuscitation (CPR survival. Methods: In this cohort study, we examined serum NR2-ab levels 1 hour after the return of spontaneous circulation (ROSC in 49 successfully resuscitated patients. Patients with traumatic or asphyxic arrests, prior neurological insults, or major medical illnesses were excluded. Participants were followed until death or hospital discharge. Demographic data, coronary artery disease risk factors, time before initiation of CPR, and CPR duration were documented.  In addition, Glasgow coma scale (GCS, blood pressure, and survival status of patients were recorded at 1, 6, 24, and 72 hour(s after ROSC. Descriptive analyses were performed, and the Cox proportional hazard model was applied to assess if NR2-ab level is an independent predictive factor of survival. Results: 49 successfully resuscitated patients were evaluated; 27 (55% survived to hospital discharge, 4 (8.1% were in vegetative state, 10 (20.4% were physically disabled, and 13 (26.5% were physically functional. Within 72 hours of ROSC all of the 12 NR2-ab positive patients died. In contrast, 31 (84% of the NR2-ab negative patients survived. Sensitivity, specificity, positive and negative likelihood ratios of NR2-ab in prediction of survival were 54.5% (95%CI=32.7%-74.9%, 100% (95%CI=84.5%-100%, infinite, and 45.5% (95%CI=28.8%-71.8%, respectively. Subsequent analysis showed that both NR2-ab status and GCS were independent risk factors of death. Conclusions: A positive NR2-ab serum test 1 hour after ROSC correlated with lower 72-hour survival. Further studies are required to validate this finding and demonstrate the value of a quantitative NR2-ab assay and its optimal time of measurement.

    In a clinical setting, especially with species of special interest, it is important to use all clinical pathology testing options for general health monitoring and diagnosis. Protein electrophoresis (EPH) has previously been shown to be an important adjunct tool in veterinary medicine. Serum samples from 18 free-ranging and 12 zoo-based koalas (Phascolarctos cinereus) were subject to EPH analysis. Significant differences were found between the two groups for the following values: total protein, albumin, beta globulins, and albumin-globulin ratio (P < 0.05). By using the combined data, the minimum-maximum values for the EPH fractions were as follows: total protein 5.0-7.8 g/dl, albumin 2.8-4.7 g/dl, alpha-1 globulins 0.5-1.1 g/dl, alpha-2 globulins 0.3-0.7 g/dl, beta globulins 0.4-1.0 g/dl, gamma globulins 0.2-1.0 g/dl, and albumin-globulin ratio 1.0-2.1.

    To evaluate the diagnostic value of baseline serum luteinizing hormone (LH) level for central precocious puberty (CPP) in girls. A total of 279 girls with precocious puberty were subjected to assessment of growth and development, bone age determination, baseline LH test, and follicle-stimulating hormone (FSH) test, gonadotropin-releasing hormone stimulation test, and other related examinations. Of the 279 patients, 175 were diagnosed with CPP and 104 with premature thelarche (PT). The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of baseline LH and FSH levels and their peak levels for CPP, and the correlation between the baseline LH level and the peak LH level was analyzed. The CPP group had significantly higher bone age, baseline LH and FSH levels, peak LH and FSH levels, and ratio of peak LH level to peak FSH level than the PT group (Pbaseline LH level and peak LH level had good diagnostic values for CPP. Among the three bone age subgroups in the CPP group (7.0-9.0 years, 9.0-11.0 years, and >11.0 years), baseline LH level showed the best diagnostic value in the >11.0 years subgroup, with the largest area under the ROC curve. At a baseline LH level of 0.45 IU/L, the Youden index reached the peak value, and the sensitivity and specificity were 66.7% and 80% respectively, for the diagnosis of CPP. At a peak LH level of 9.935 IU/L, the Youden index reached the peak value, and the sensitivity and specificity were 74.8% and 100% respectively, for the diagnosis of CPP. The baseline LH level was positively correlated with the peak LH level (r=0.440, PBaseline LH level can be used as an primary screening index for the diagnosis of CPP. It has a certain diagnostic value for CPP at different bone ages, and may be used as a monitoring index during the treatment and follow-uP.

    Numerous studies have assessed the diagnostic value of serum p53 (s-p53) antibody in patients with colorectal cancer (CRC); however, results remain controversial. The present study aimed to comprehensively and quantitatively summarize the potential diagnostic value of s-p53 antibody in CRC. The present study utilized databases, including PubMed and EmBase, systematically regarding s-p53 antibody diagnosis in CRC, accessed on and prior to 31 July 2016. The quality of all the included studies was assessed using quality assessment of studies of diagnostic accuracy (QUADAS). The result of pooled sensitivity, pooled specificity, positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were analyzed and compared with overall accuracy measures using diagnostic odds ratios (DORs) and area under the curve (AUC) analysis. Publication bias and heterogeneity were also assessed. A total of 11 trials that enrolled a combined 3,392 participants were included in the meta-analysis. Approximately 72.73% (8/11) of the included studies were of high quality (QUADAS score >7), and all were retrospective case-control studies. The pooled sensitivity was 0.19 [95% confidence interval (CI), 0.18-0.21] and pooled specificity was 0.93 (95% CI, 0.92-0.94). Results also demonstrated a PLR of 4.56 (95% CI, 3.27-6.34), NLR of 0.78 (95% CI, 0.71-0.85) and DOR of 6.70 (95% CI, 4.59-9.76). The symmetrical summary receiver operating characteristic curve was 0.73. Furthermore, no evidence of publication bias or heterogeneity was observed in the meta-analysis. Meta-analysis data indicated that s-p53 antibody possesses potential diagnostic value for CRC. However, discrimination power was somewhat limited due to the low sensitivity.

    Objective: To investigate the diagnostic value of combined detection of serum tumor markers, including CEA, CA125, neuron-specific enolase (NSE) and cytokeratin fragment antigen 21-1 (CYFRA21-1) for lung cancer patients. Methods: The subjects involved 138 diagnosed lung cancer patients (82 males, 56 females, average age 58.6 years, from October 2010 to March 2012), 96 patients with benign lung diseases (56 males, 40 females, average age 51.3 years) and 45 healthy adults (30 males, 15 females, average age 43.9 years). The pathological types of lung cancer consisted of 66 squamous cell carcinoma (SCC), 52 adenocarcinoma and 20 small cell lung cancer (SCLC). The serum levels of CEA, CA125, NSE and CYFRA21-1 were measured with electrochemiluminescence immunoassay. The diagnostic efficacy for different pathological types was compared among each single tumor marker and combination of tumor markers. One-way analysis of variance q test were used for statistical analysis. Results: The serum levels of CEA, CA125, NSE and CYFRA21-1 in patients with lung cancer were higher than those in patients with benign lung diseases and in healthy subjects (CEA: (19.99±30.99), (10.78±19.77), (3.25±3.42) μg/L; CA125: (79.70±95.98), (44.96±44.97), (20.66±7.13) μg/L; NSE: (35.23±40.22), (15.31±8.42), (13.30±5.65) μg/L; CYFRA21-1: (18.07±43.71), (8.30±8.83), (3.13±1.60) μg/L; F=4.481, 5.436, 4.776, 6.002, all P<0.05). The highest level of CEA, NSE or CYFRA21-1 were found in adenocarcinoma (F=4.932, P<0.05), SCLC (F=5.119, P<0.05) or SCC (F=5.378, P<0.05), respectively. The highest sensitivity tumor markers for SCC, SCLC and adenocarcinoma were CYFRA21-1 (78.8%, 52/66), NSE (75.0%, 15/20) and CEA (57.7%, 30/52), respectively. In combined detection, the highest sensitivity combinations for SCC, SCLC and adenocarcinoma were CEA + CYFRA21-1 + NSE (89.4%, 59/66), CEA + CYFRA21-1 + NSE (80.0%, 16/20) and CEA + CA125 + NSE (78.8%, 41/52), respectively. Conclusions: Combined detection

    Several studies have reported increased levels of phosphate after cardiac arrest. Given the relationship between phosphate level and the severity of ischaemic injury reported in previous studies, higher phosphate levels may be associated with worse outcomes. We investigated the prognostic value of phosphate level after the restoration of spontaneous circulation (ROSC) in adult cardiac arrest patients. This study was a retrospective observational study including adult cardiac arrest survivors treated at the Chonnam National University Hospital between January 2014 and June 2017. From medical records, data regarding clinical characteristics, outcome at hospital discharge, and laboratory parameters including phosphate levels after ROSC were collected. The primary outcome was poor outcome at hospital discharge, defined as Cerebral Performance Categories 3-5. Of the 674 included patients, 465 had poor outcome at hospital discharge. Serum phosphate level was significantly higher in patients with poor outcome than in those with good outcome (p level was correlated with time to ROSC (r = 0.350, p level. In multivariate analysis, a higher phosphate level was independently associated with poor outcome at hospital discharge (odds ratio, 1.432; 95% CI, 1.245-1.626; p level after ROSC was independently associated with poor outcome at hospital discharge in adult cardiac arrest patients. However, given its modest prognostic performance, phosphate level should be used in combination with other prognostic indicators. Copyright © 2018 Elsevier B.V. All rights reserved.

    POEMS syndrome is a rare plasma cell dyscrasia. Serum concentrations of the monoclonal protein in this disorder are typically low, and inapplicable to monitor disease activity in most cases, resulting in limited practical and prognostic values. Novel immunoassays measuring isotype-specific heavy/light chain (HLC) pairs showed its utility in disease monitoring and outcome prediction in several plasma cell dyscrasias. We report results of HLC measurements in 90 patients with POEMS syndrome. Sixty-six patients (73%; 95% confidence interval, 63-82%) had an abnormal HLC ratio at baseline. It could stratify the risk of disease relapse and was strongly associated with worse progression-free survival in a multivariate analysis (P = 0.021; hazard ratio [HR] 6.89, 95% CI 1.34-35.43). After therapy, HLC ratios improved, with 43 patients (48%) remaining abnormal. The post-therapeutic HLC ratio, if abnormal, also remained as an independent prognostic factor associated with worse progression-free survival (P = 0.019; HR 4.30, 95% CI 1.27-14.56). These results suggest the prognostic utility of HLC ratios in clinical management of POEMS patients. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The TRAb content of the thyroid diseases 758 cases (including the first visit thyroidism group 166 cases; the thyroidism group with normal thyroid function by medicine treatment 198 cases, the group with abnormal thyroid function by medicine treatment 86 cases, the group with lower thyroid function 24 cases, the group with normal thyroid function by 131 I treatment 104 cases, the subacute thyroiditis group 48 cases, the simple goiter group 52 cases, the primary hypothyroidism group 80 cases) and the normal control group 62 cases are detected. The results show that the values of TRAb are much higher in the groups with normal or abnormal thyroid function by medicine treatment, the group with lower thyroid function, the group with 131 I treatment and the group with primary hypothyroidism than that of control group (P 0.05). The differential of the TRAb average and positive rate is obvious between the groups with normal and abnormal thyroid function by medicine treatment (P 131 I treatment (P < 0.01). The TRAb levels in serum are higher in the patients with thyroidism and primary hypo-thyroidism, and the TRAb levels are normal in the patients with subacute thyroiditis and simple goiter. So, TRAb is a auxiliary index in the diagnosis of thyroidism and hypo-thyroidism and also a differential diagnosis index about the thyroidism and subacute thyroiditis. At the same time, TRAb is an important index in evaluating the autoimmune monitoring function of the body, and stopping the use of thyroid medicine

    Full Text Available Objective: To analyze the evaluation value of coronary CT angiography for coronary plaque features and its correlation with platelet function and serum biochemical indexes. Methods: A total of 450 patients with coronary heart disease were divided into calcified plaque group (CT value≥130HU (n=117, soft plaque group (CT value≤60HU (n=150 and mixed plaque group (CT value 60-130HU (n=183 by coronary CT angiography (CTA, and 100 healthy subjects who received physical examination in our hospital during the same period were selected as control group. Differences in platelet function and serum biochemical indexes were compared among four groups of patients, and the judgment value of atheromatous plaque CT value from CTA for the severity of coronary heart disease was analyzed. Results: Platelet function parameters MPV, TEG-MA, P-selectin, PDGF-BB and vWF levels in peripheral blood of soft plaque group were higher than those of the other three groups; inflammatory factors CRP, IL-6, IL-12, IL-18 and IL-23 content in serum were higher than those of the other three groups; chemokines MCP-1, CXCL16, Fractalkine and RANTES content in serum were higher than those of the other three groups; adipocytokines Leptin and RBP4 content in serum were higher than those of the other three groups while SFRP5 content was lower than those of the other three groups. Atheromatous plaque CT value in patients with coronary heart disease was directly correlated with platelet function and the content of serum biochemical indexes. Conclusions: Coronary CTA can accurately assess coronary atheromatous plaque features, and can also be a reliable noninvasive method to judge coronary heart disease severity, treatment prognosis and so on.

    Objective: To investigate the clinical significance of changes of serum pepsinogen and gastrin levels in patients with gastric/duodenal ulcer. Methods: Serum pepsinogen I (PG I), pepsinogen II (PGII), gastrin levels and PG I/PG II ratio were determined with RIA in 100 controls, 61 patients with duodenal ulcer, 46 patients with gastric ulcer, 66 patients with gastric cancer and 101 patients with chronic gastritis. Results: In patients with peptic ulcer (gastric/duodenal), the serum levels of PG I, PG II and PG I/PG II ratio were significantly higher than those in controls (P<0.001); the serum gastrin levels were also significantly higher than those in controls and patients with chronic gastritis (P<0.001), but lower than those in patients with gastric cancer (P<0.001). Among patients with peptic ulcer, the serum PG I level and PG I/PG II ratio were significantly higher in patients with duodenal ulcer than those in patients with gastric ulcer (P<0.001). Conclusion: Excessive high serum levels of PG I, PG II, gastrin and PG I/PG II ratio were some of the high risk factors for peptic ulcer. Those were useful serum markers for diagnosis and follow-up of the disease. (authors)

    Objective: To study clinical value of the joint measurement of serum concentrations of type IV collagen (IV C) and laminin (LN) in patients with diabetic nephropathy (DN) by radioimmunoassay (RIA). Methods: Serum concentrations of IV C, LN were measured by RIA in 35 diabetic patients with normalbuminuria (group A), 28 cases of microalbuminuria (group B), 15 cases of macroalbuminuria (group C) and 30 normal subjects as control . Results: The serum concentrations of IV C, LN in total 78 diabetic patients [(97.6 ± 19.2), (132.4 ± 31.5) μg/L] were higher than that of the controls [(77.4 ± 8.2), (101.5 ± 17.6) μg/L, P<0.05], especially in group B and C, it was remarkably higher compared with the controls (P<0.05, P<0.01). There was significant positive correlation of serum IV C, LN to diabetic duration and the levels of blood urea nitrogen (BUN), creatinine (Cr), urinary albumin excretion rate (UAER). Conclusions: The results suggest that the joint measurement of serum levels of IV C, LN and UAER in DN patients might better evaluate the development process of DN, and be of help for early diagnosis and treatment of DN. Serum levels of IV C, LN and UAER in DN patients may become the reliable clinical markers for assessing the severity and predicting the prognosis of DN

    Conclusions: Serum TN-C might be a novel marker reflecting active structural remodeling in the myocardium following infarction, with high TN-C levels at acute stages possibly predicting progression of LV remodeling. Also, the incorporation of a combination of serum TN-C and plasma BNP levels may improve risk stratification for congestive heart failure after AMI. Further studies on large scale are needed for more evaluation of TN-C role in HF.

    To analyze the prognostic value of baseline serum free light chain (sFLC) in light-chain (AL) cardiac amyloidosis. Twenty-seven patients with AL cardiac amyloidosis were retrospectively reviewed from January 2014 to January 2015. sFLC was measured by immuoturbidimetric assay. Baseline characteristics, echocardiographic parameters and electrocardiogram data were analyzed. According to the median baseline dFLC (involved sFLC minus uninvolved sFLC), patients were categorized into either the low dFLC(≤ 307 mg/L) or the high dFLC group (>307 mg/L). More subjects in the high dFLC group with early/late diastolic mitral velocity ratio (E/A ratio) over 2 (71.4% vs 30.8%, P=0.035), and subjects in this group had a shorter median survival time than those in the low dFLC group (3 months vs 17 months, P=0.004). A similar phenomenon for median survival time was observed when the subjects were redivided either by a new cut-off value of 180 mg/L for dFLC (low dFLC group: 17 months; high dFLC group: 4 months, P=0.014) or a κ/λ ratio, in which subjects with κ type sFLC-ratio ≤ 19.6 and λ type sFLC-ratio>0.065 were in the low sFLC-ratio group (17 months) and those with κ type sFLC-ratio > 19.6 and λ type sFLC-ratio ≤ 0.065 were in the high sFLC-ratio group (4 months, P=0.023). In multivariate analysis, dFLC and New York Heart Association (NYHA)classification of cardiac function were two risk factors associated with all-cause mortality in patients, among which the hazard ratio for higher dFLC was 4.28 (95%CI 1.55-11.8, P=0.005). The level of sFLC could be a marker for the prognosis of AL cardiac amyloidosis.

    Enteroviruses (EV) are a common cause of aseptic meningitis in children. Virological diagnosis of EV meningitis is currently based on the detection of the viral genome in the cerebrospinal fluid (CSF). This study attempted to determine the correlation and the temporality of the polymerase chain reaction (PCR) assay in serum and CSF and to evaluate the possibility of diagnosing EV infection only on the serum PCR. The EV genome was sought by RT real-time PCR (Smart Cycler EV Primer and Probe Set(®), Cepheid) in CSF and serum, collected at the same time, for all children who underwent a lumbar puncture for suspected meningitis, between 1 June and 31 July 2010 at the Versailles Hospital. Forty-four patients were included in the study. EV infection was documented for 22 of them. In 10 patients, the EV genome was detected in CSF only; in 3 patients in serum only, and in 9 patients in both. Among patients with acute EV neurological infection, viremic children were significantly younger (1.6 months versus 5.8 years; Pvalue of EV PCR in serum. It suggests that in some children and under certain conditions (age >3 months, clinical and biological compatibility with a viral infection, no previous antibiotic therapy, time from symptom onset to blood sampling <30 h, PCR in serum analyzed within 3h), PCR in serum, when positive, is a possible alternative. Therefore, it may be possible to diagnose EV infection without performing a lumbar puncture in a limited number of young children (11.4% of our suspected cases). This study needs to be reinforced by a multicenter study with a broader panel of patients. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity affecting both adults and children characterized by neurotoxicity often in setting of hypertension coupled with distinct brain magnetic resonance imaging features. Decreased serum albumin level has been suggested to correlate with the presence of vasogenic brain edema in adult PRES. Serum albumin has thus been hypothesized to protect against neurotoxicity in PRES by reducing vasogenic brain edema through its role in maintaining plasma osmotic pressure and endothelial integrity. The purpose of our study was to investigate if such correlation between decreased serum albumin level and PRES-related vasogenic edema could be found in children. We conducted a retrospective study of 25 pediatric patients diagnosed with PRES. Underlying clinical conditions, presenting symptoms, blood pressures, and serum albumin levels at onset of symptoms were collected. Brain MR imaging studies were reviewed. We used a quantitative method to evaluate the degree of vasogenic edema by measuring apparent diffusion coefficient (ADC) values of the T2-FLAIR hyperintense brain lesions. No significant correlation was found between serum albumin level and degree of PRES-related vasogenic edema. A significant correlation was found between elevated blood pressure and degree of vasogenic edema in the temporal lobes (p = 0.02 and 0.04, respectively) but not in the other cerebral lobes or cerebellum. Our initial results suggest blood pressure, not serum albumin level, as a main biomarker for brain edema in children with PRES. Thus, our study does not suggest a protective role of serum albumin against PRES-related neurotoxicity in children. (orig.)

    Full Text Available Objective: To study the value of preoperative serum LC3 and MMPs combined with TSH detection in diagnosis of papillary thyroid carcinoma and provide reference for clinical diagnosis and treatment. Methods: A total of 80 cases of patients with papillary thyroid carcinoma treated in our hospital from March 2010 to March 2014 were analyzed, and serum TSH, MMP2/9, TIMP1/2 and LC3 levels of patients before operation were detected by ELISA. Healthy subjects and patients with benign neoplasm of thyroid during the same period were taken as control. Results: Serum TSH, MMP2, MMP9 and LC3 levels in patients with papillary thyroid carcinoma significantly increased, TIMP1 and TIMP2 levels significantly decreased, and compared with healthy subjects and patients with benign neoplasm of thyroid, there were significant statistical differences; at the same time, above parameters in serum were not related to gender, but closely related to age, clinical stage and diameter of tumor as well as lymph node. Conclusion: Preoperative detection of serum LC3 and MMPs combined with TSH levels has important reference significance in diagnosis of papillary thyroid carcinoma.

  15. Serum bilirubin value predicts hospital admission in carbon monoxide-poisoned patients. Active player or simple bystander?

    Directory of Open Access Journals (Sweden)

    Gianfranco Cervellin

    Full Text Available OBJECTIVES: Although carbon monoxide poisoning is a major medical emergency, the armamentarium of recognized prognostic biomarkers displays unsatisfactory diagnostic performance for predicting cumulative endpoints. METHODS: We performed a retrospective and observational study to identify all patients admitted for carbon monoxide poisoning during a 2-year period. Complete demographical and clinical information, along with the laboratory data regarding arterial carboxyhemoglobin, hemoglobin, blood lactate and total serum bilirubin, was retrieved. RESULTS: The study population consisted of 38 poisoned patients (23 females and 15 males; mean age 39±21 years. Compared with discharged subjects, hospitalized patients displayed significantly higher values for blood lactate and total serum bilirubin, whereas arterial carboxyhemoglobin and hemoglobin did not differ. In a univariate analysis, hospitalization was significantly associated with blood lactate and total serum bilirubin, but not with age, sex, hemoglobin or carboxyhemoglobin. The diagnostic performance obtained after combining the blood lactate and total serum bilirubin results (area under the curve, 0.90; 95% CI, 0.81-0.99; p<0.001 was better than that obtained for either parameter alone. CONCLUSION: Although it remains unclear whether total serum bilirubin acts as an active player or a bystander, we conclude that the systematic assessment of bilirubin may, alongside lactate levels, provide useful information for clinical decision making regarding carbon monoxide poisoning.

    The aim of this study was to ascertain the diagnostic value of serum squamous cell carcinoma antigen (SCCA) and SCCA-IgM for hepatocellular carcinoma (HCC). After a comprehensive search of PubMed and Web of Science databases, we identified eligible studies on the diagnostic value serum SCCAs for HCC. The quality of the eligible studies was assessed using the revised Quality Assessment for Studies of Diagnostic Accuracy (QUADAS-2) tool. The overall diagnostic value of SCCAs for HCC was pooled using a bivariate model. Twelve studies were included in this systematic review and meta-analysis. The pooled sensitivities for SCCA and SCCA-IgM were 0.61 (95% confidence interval [CI], 0.37-0.81) and 0.70 (95% CI, 0.55-0.82), respectively. The corresponding specificities were 0.80 (95% CI, 0.52-0.94) and 0.62 (95% CI, 0.51-0.72), respectively. The areas under summary receiver operating characteristic (sROC) curves for SCCA and SCCA-IgM were 0.76 (95% CI, 0.72-0.80) and 0.70 (95% CI, 0.66-0.74), respectively. Major design deficiencies of the included studies were two-gate design and partial verification bias. Therefore, we concluded that both serum SCCA and SCCA-IgM have a fair diagnostic value for HCC.

    Protein electrophoresis of serum samples from endangered, wild whooping cranes ( Grus americana ) was performed to help assess the health of the only self-sustaining, migratory population in North America. Serum samples from wild adult cranes (n = 22) were taken at Aransas National Wildlife Refuge, Texas, USA during winter. Wild juvenile cranes (n = 26) were sampled at Wood Buffalo National Park, Northwest Territories, Canada, in midsummer. All captive crane samples were acquired from the International Crane Foundation, Baraboo, WI, USA. Captive adult cranes (n = 30) were sampled during annual examinations, and archived serum samples from captive juvenile cranes (n = 19) were selected to match the estimated age of wild juveniles. Wild juveniles had significantly lower concentrations of all protein fractions than wild adults, except for prealbumin and γ globulins. All protein fraction concentrations for wild juveniles were significantly lower compared with captive juveniles, except for prealbumin and γ globulins, which were higher. Wild adults had significantly greater γ globulin concentrations than captive adults. Captive juveniles had significantly lower prealbumin and albumin concentrations and albumin : globulin ratios than captive adults. The higher γ globulin concentrations in wild versus captive cranes are likely because of increased antigenic exposure and immune stimulation. Protein fraction concentrations vary significantly with age and natural history in this species. Reference intervals for serum protein electrophoresis results from captive adult whooping cranes are provided in this study.

    Full Text Available Abstract Background Reference data for plasma lipids and blood pressure are not available for Asian Indian adolescents. This study aimed to develop representative age- and sex- specific percentile reference data for serum lipids [total cholesterol (TC, triglycerides (TG, low density lipoprotein cholesterol (LDL-C, high density lipoprotein cholesterol (HDL-C, non-HDL cholesterol] and blood pressure for urban Asian Indian adolescents aged 14–18 years. The sample consisted of 680 boys and 521 girls aged 14–18 years from the cross-sectional population survey, Epidemiological Study of Adolescents and Young Adults (ESAY for whom the data for serum lipid levels and blood pressure were recorded. Smoothed age- and sex- specific 5th, 10th, 25th, 50th, 75th, 85th, 90th and 95th percentiles where derived using LMS regression. Results Percentile-based reference data for serum lipids and blood pressure are presented for adolescent Asian Indian boys and girls for the first time. Asian Indian adolescents had lower levels of serum TC, LDL-C and HDL-C and higher TG than their counterparts in the USA. Interesting trends in TC and HDL-C levels where observed, which might reflect changes in dietary pattern and physical activity in this age group in India. Conclusion These reference data could be used to identify adolescents with an elevated risk of developing dyslipidemia, hypertension and cardiovascular disorders, to plan and implement preventive policies, and to study temporal trends.

    2011-01-01

    To evaluate the clinical value of detection of concentration of β-Crosslaps, PINP and N-MID in postmenopausal women with osteoporosis, 116 postmenopausal women were detected by dual X-ray absorptionmetry and divided into NOP group (51 cases) and OP group (65 cases). The serum levels of three bone markers (β-Crosslaps, PINP and N-MID) were measured. The results showed that serum levels of β-Crosslaps, PINP and N-MID in OP group were significantly higher than that in NOP group (P<0.01). It was suggested that three bone markers level might be closely related with osteoporosis in postmenopausal women. The combined detection of bone markers and bone mineral density has important clinical value in the diagnosis of osteoporosis in postmenopausal women. (authors)

    To determine the significance of increased serum direct bilirubin level for lymph node metastasis (LNM) in Chinese rectal cancer patients, after those with known hepatobiliary and pancreatic diseases were excluded. A cohort of 469 patients, who were treated at the China-Japan Friendship Hospital, Ministry of Health (Beijing, China), in the period from January 2003 to June 2011, and with a pathological diagnosis of rectal adenocarcinoma, were recruited. They included 231 patients with LNM (49.3%) and 238 patients without LNM. Follow-up for these patients was taken through to December 31, 2012. The baseline serum direct bilirubin concentration was (median/inter-quartile range) 2.30/1.60-3.42 μmol/L. Univariate analysis showed that compared with patients without LNM, the patients with LNM had an increased level of direct bilirubin (2.50/1.70-3.42 vs 2.10/1.40-3.42, P = 0.025). Multivariate analysis showed that direct bilirubin was independently associated with LNM (OR = 1.602; 95%CI: 1.098-2.338, P = 0.015). Moreover, we found that: (1) serum direct bilirubin differs between male and female patients; a higher concentration was associated with poor tumor classification; (2) as the baseline serum direct bilirubin concentration increased, the percentage of patients with LNM increased; and (3) serum direct bilirubin was associated with the prognosis of rectal cancer patients and higher values indicated poor prognosis. Higher serum direct bilirubin concentration was associated with the increased risk of LNM and poor prognosis in our rectal cancers.

    Full Text Available Aims: Pregnancies achieved by in vitro fertilization (IVF are at increased risk of adverse outcome. The main objective of this study was to evaluate the predictive value of β-human chorionic gonadotrophin (β-HCG and age of the patient for the successful outcome in IVF. Materials and Methods: A retrospective study was done in 139 pregnancies after IVF at single IVF center from June 2007 to July 2012. The age of the patient and initial serum values of β-HCG on day 14 of embryo transfer were correlated with ongoing pregnancy (>12 weeks gestation. Results: The β-HCG level on day 14 of more than 347 mIU/ml has a sensitivity of 72.2% and specificity of 73.6% in prediction of pregnancy beyond 12 weeks period of gestation. Positive likelihood ratio (LR is 2.74 and negative LR is 0.37, (receiver operating characteristic area = 0.79. Discussion: In IVF cycles, there is a lot of stress on the couples while the cycle is going on. There was a positive correlation between the higher values of early serum β-HCG levels and ongoing pregnancy. Hence, it can be used as an independent predictor of a successful outcome of IVF cycle. Conclusion: We concluded from our study that early serum β-HCG can be used as a predictor of a successful outcome in IVF.

    Cheetahs in captivity have a high prevalence of chronic renal diseases. We ultrasonographically evaluated the renal volumes, a variety of renal dimensions, interarcuate artery resistive indices (RI) as well as aortic diameters and the length of the ventral aspect of the 6th lumbar vertebrae in 27 aged semi-captive anesthetized cheetahs. Renal size, dimensions and ratios were compared to urine specific gravity, serum creatinine and urea values. There were minimal differences for all values between left and right kidneys. Mean kidney length was 65.1 mm (range 55.2-76.9) with left kidney length ratios to L6 length being 1.60 (range 1.27-2.06) and to the aortic diameter 7.69 (range 4.54-10.72). Significant correlations between left renal length as well as length:L6 ratio to creatinine values were found ((r - 0.66) and (r - 0.60) respectively). The mean RI values of the different sedation/anesthetic protocols ranged from 0.46-0.55. Left renal length and L6 ventral vertebral body length as well as left kidney RI values should be routinely measured in all cheetah abdominal ultrasound examinations. These measurements, together with serum creatinine, urea and urine specific gravity values may be relatively sensitive indicators of early renal pathology in the absence of gross ultrasonographic changes.

    Resistin is a novel adipokine that is suggested to be involved in inflammatory conditions and atherosclerosis. To investigate the prognostic importance of resistin in acute myocardial infarction (AMI) patients. Resistin levels were measured in a population of 132 patients with AMI, of whom 72 (54%) had a diagnosis of ST elevation myocardial infarction (STEMI), and 60 (46%) had non-ST elevation myocardial infarction (NSTEMI). Thirty-three consecutive subjects who were referred to elective coronary angiography due to chest pain evaluation with normal coronary angiograms served as controls. All patients were followed-up for the occurrence of major adverse cardiac events (MACE). There was a significant increase in serum resistin levels in patients with AMI compared to controls (3.71 ± 4.20 vs. 2.00 ± 1.05, p = 0.001, respectively). However, serum resistin levels were similar in patients with STEMI and NSTEMI. (4.26 ± 5.11 vs. 3.06 ± 2.64, p = 0.49, respectively). The patients with MACE had significantly higher levels of serum resistin levels compared to either the AMI or the control group (6.35 ± 5.47, p = 0.005, respectively). Logistic regression analysis revealed that resistin, left ventricular ejection fraction, and coronary artery bypass graft were independent predictors of MACE in AMI patients (OR = 1.11, 95% CI 1.01-1.22, p = 0.03 and OR = 3.84, 95% CI 1.26-11.71, p = 0.018, respectively). Serum resistin level was increased in patients with AMI and constituted a risk factor for MACE in this group.

    Full Text Available Serum methylmalonic acid (MMA is elevated in vitamin B-12 deficiency and in kidney dysfunction. Population reference values for serum MMA concentrations in post-folic acid fortification period are lacking. Aims of this study were to report the population reference values for serum MMA and to evaluate the relation between serum MMA and sex, age, race-ethnicity, kidney dysfunction and vitamin B-12. We used data from three National Health and Nutrition Examination Surveys, 1999–2000, 2001–2002 and 2003–2004 conducted after folic acid fortification commenced (n = 18,569. Geometric mean MMA was ≈22.3% higher in non-Hispanic white compared to non-Hispanic black (141.2 vs. 115.5 nmol/L and was ≈62.7% higher in >70 years old persons compared to 21–30 years old persons (196.9 vs. 121.0 nmol/L. Median serum MMA was ≈28.5% higher in the 1st the quartile of serum vitamin B-12 than in the 4th quartile of serum vitamin B-12 and was ≈35.8% higher in the 4th quartile of serum creatinine than in the 1st quartile of serum creatinine. Multivariate-adjusted serum MMA concentration was significantly associated with race-ethnicity (p < 0.001 and age (p < 0.001 but not with sex (p = 0.057. In this large US population based study, serum MMA concentrations presented here reflect the post-folic acid fortification scenario. Serum MMA concentrations begin to rise at the age of 18–20 years and continue to rise afterwards. Age-related increase in serum MMA concentration is likely to be due to a concomitant decline in kidney function and vitamin B-12 status.

    Full text: Determination of the normal values of glomerular filtration rate (GFR) is an essential part of the evaluation of patient with kidney disease. GFR almost linearly decreases with age at a mean annual rate of 0.8 ml/min/1.73 m2 over the age of 30 years old. According to NHANES III mean GFR for population with age > 60 years was 80 mL/min/1.73 m2. It is recommended for each centre to determine their own normal values of GFR for different age groups particularly in geriatric population. Recently, serum cystatin-C has been proposed as a new endogenous marker of glomerular filtration rate. Aim of the study was to determination of normal values of glomerular filtration rate (GFR) in geriatrics in Bandung and its correlation with serum Cystatin-C levels. Subjects were 24 males and 36 females (mean age 66.71 ± 6.7 years; range 60-87 yrs), without any renal and/or systemic disease. Creatinine clearance was estimated by using Cockroft-Gault formula and serum cystatin-C level were determined by using particle enhanced immunonephelometric method, while GFR values were determined by external body counting methods using Tc-99m DTPA ( Gates' methods ). Pearson correlation was used to determine correlation between variables and a P value < 0.05 is considered significant. Results and Discussion. Mean total GFR was 67.57 ml/min/1.73 m2 (SD ± 16.02), range from 45 to 100 ml/min/1.73 m2. Mean total GFR for male was 69.46 ml/min/1.73 m2, and female was 66.31 ml/min/1.73 m2, the difference was statistically significant (p < 0.05). The results were lower than NHANES III values. There was a better correlation between total GFR and cystatin-C level (r = -0.522 and p < 0.001) compared to total GFR and creatinine clearance (r 0.306 and p < 0.005). Mean creatinine clearance was 57.93 ml/min and serum cystatin-C was 0.97 mg/dl, the correlation was statistically significant (r -0.414 and p < 0.005). Conclusions: The normal values of GFR in geriatric population in Bandung were 69

    Objective: To investigate the diagnostic value of combined determination of serum NSE, CA242, tissue polypeptide antigen (TPA) and CEA levels in patients with primary lung cancer. Methods: Serum NSE, CA242, TPA and CEA levels were determined with ELISA in (1) 102 patients with various types of primary lung carcinoma (adenocarcinoma 38, squamous cell carcinoma 32, small cell lung carcinoma 32) (2) 33 patients with open lung T. B. and (3) 30 controls. Results: (1) In patients with lung cancer, serum levels of all the four markers were increased and significantly higher than their respective values in patients with open lung T.B. and controls. (2) Positive rate of combined any two markers were 75% for adenocarcinoma, 50% for squamous cell carcinoma and 65% for small cell lung carcinoma, while false positive rate was only 9% for T.B patients and none for the controls. (3) The most appropriate single marker for each specific type of lung cancer was: NSE for SCLC (sensitivity 72%, specificity 97%, CA242 for adenocarcinoma sensitivity 62%, specificity 90%). Conclusion: Combined determination of these tumor markers would improve the sensitivity and specificity for diagnosis of primary lung carcinoma. (authors)

    To determine if the serum free light chain (FLC) ratio has prognostic value in patients with symptomatic multiple myeloma (MM), baseline serum samples from a well-characterized cohort of 790 newly diagnosed MM patients were tested with the FLC assay. FLC ratio was calculated as kappa/lambda (reference range 0.26-1.65). On the basis of the distribution of values, a cutpoint kappa/lambda FLC ratio of 32 was chosen for further analysis. Overall survival was significantly inferior in patients with an abnormal FLC ratio of 32 (n=479) compared with those with an FLC ratio between 0.03 and 32 (n=311), with median survival of 30 versus 39 months, respectively. We incorporated abnormal FLC ratio with the International Staging System (ISS) risk factors (that is, albumin or=3.5 g/l), to create a risk stratification model with improved prognostic capabilities. Patients with 0, 1, 2 or 3 adverse risk factors had significantly different overall survival, with median survival times of 51, 39, 30 and 22 months, respectively (P<0.001). These findings suggest that the serum FLC ratio at initial diagnosis is an important predictor of prognosis in myeloma, and can be incorporated into the ISS for improved risk stratification.

    S100B protein detected in the serum of patients with cutaneous melanoma has been long reported as a prognostic biomarker. However, no consensus exists on its implementation in the routine clinical setting. This study aimed to comprehensively and quantitatively summarize the evidence on the suitability of serum S100B to predict patients' survival. Twenty-two series enrolling 3393 patients with TNM stage I to IV cutaneous melanoma were reviewed. Standard meta-analysis methods were applied to evaluate the overall relationship between S100B serum levels and patients' survival (meta-risk). Serum S100B positivity was associated with significantly poorer survival (hazard ratio [HR] = 2.23, 95% CI: 1.92-2.58, p < 0.0001). Between-study heterogeneity was significant, which appeared to be related mainly to dissemination bias and the inclusion of patients with stage IV disease. Considering stage I to III melanoma (n = 1594), the meta-risk remained highly significant (HR = 2.28, 95% CI: 1.8-2.89; p < 0.0001) and studies' estimates were homogeneous. Subgroup analysis of series reporting multivariate survival analysis supported S100B as a prognostic factor independent of the TNM staging system. Our findings suggest that serum S100B detection has a clinically valuable independent prognostic value in patients with melanoma, with particular regard to stage I-III disease. Further investigation focusing on this subset of patients is justified and warranted before S100B can be implemented in the routine clinical management of melanoma. (c) 2008 Wiley-Liss, Inc.

    To investigate levels of TSGF,CA125 and CEA as a panel for early diagnosis of overian cancer, the levels of three tumor markers(TSGF,CA125 and CEA) in serum were determined in 85 patients with ovarian cancer, 54 patients with benign tumor and 76 healthy control. The results showed that the levels of three tumor markers in ovarian cancer patients were significantly higher than those in benign tumor patients and controls(P<0.05). Combined detection of the three markers may greatly improve the diagnostic accuracy of overian cancer. (authors)

    Autologous stem cell transplantation (ASCT) is the gold standard therapy for suitable multiple myeloma (MM) patients after induction with high dose therapy. To date, the evidence of a reliable marker of prognosis in these cases remains scarce. Our aim was to evaluate appearance of unrelated atypical serum immunofixation patterns (ASIPs) as a marker of prognosis in MM patients submitted to ASCT. We retrospectively analysed data from 65 patients. Interestingly, we observed that presence of ASIPs was associated with longer progression-free survival and longer overall survival. Our results suggested that presence of ASIPs could be a novel marker of good prognosis in MM patients submitted to ASCT.

    Objective: To investigate the early diagnostic value of measurement of changes of serum leptin, α 1 -acid glycoprotein (AAG) and alphal-antitrypsine (α 1 AT)levels in patients with lung cancer. Methods: Serum leptin (with RIA)and serum AAG and α 1 AT (with ELISA) levels were determined in 89 patients with lung cancer and 60 controls. Results: The serum levels of leptin, AAG and α 1 AT in patients with lung cancer were significantly higher than those in the controls. No correlations among the investigated serum parameters were demonstrated. Conclusion: Serum leptin, AAG and α 1 AT levels are higher in patients with lung cancer. They may play inde-pendent roles in the development of lung cancer. Detection of the serum concentrations of leptin, AAG and α 1 AT is valuable for early diagnosis of lung cancer. (authors)

    The purpose of this study was to determine the nutritional value of diets with protein from two marine species (Haliotis tuberculata and Anemonia viridis) as compared to a high-quality protein reference based on casein or casein supplemented with olive oil. We also investigated the effects of these diets on serum lipid levels. Male rats were fed these diets for 23 days. Protein quality indicators (true digestibility, net protein utilization, biological value) were similar to those obtained for casein-based feeds except for lower true digestibility and net protein utilization values for the Anemonia viridis feed. HDL-cholesterol level was significantly higher (p < 0.05) in the groups fed marine species or casein supplemented with olive oil than in the casein group. Total-cholesterol level was higher in the group fed Haliotis tuberculata fed than in the other groups. These results suggest that these marine species are a good protein source, and that they may have positive effects on serum cholesterol level.

    Wheezing is common in childhood. However, current prediction models of pediatric asthma have only modest accuracy. Novel biomarkers and definition of subphenotypes may improve asthma prediction. Interleukin-1-receptor-like-1 (IL1RL1 or ST2) is a well-replicated asthma gene and associates with eosinophilia. We investigated whether serum sST2 predicts asthma and asthma with elevated exhaled NO (FeNO), compared to the commonly used Asthma Prediction Index (API). Using logistic regression modeling, we found that serum sST2 levels in 2-3 years-old wheezers do not predict doctors' diagnosed asthma at age 6 years. Instead, sST2 predicts a subphenotype of asthma characterized by increased levels of FeNO, a marker for eosinophilic airway inflammation. Herein, sST2 improved the predictive value of the API (AUC=0.70, 95% CI 0.56-0.84), but had also significant predictive value on its own (AUC=0.65, 95% CI 0.52-0.79). Our study indicates that sST2 in preschool wheezers has predictive value for the development of eosinophilic airway inflammation in asthmatic children at school age. © 2017 EAACI and John Wiley and Sons A/S.

    Objective: To investigate the diagnostic value of combined detection of four tumor markers in patients with possible malignant change in liver disorders. Methods: Serum AFP, CEA, CA199 and SF levels were determined with chemiluminescence immunoassay (CLIA) in 49 patients with primary liver carcinoma, 7 patients with metastatic liver carcinoma, 40 patients with hepatic cirrhosis, 47 patients with HBV hepatitis and 30 controls. Results: The serum levels of AFP, CEA, SF in patients with primary hepatic cancer and serum levels of AFP, SF in patients with hepatic cirrhosis were all significantly higher than those in controls (P 0.05). Moreover, positive rate of combined determination of AFP, CEA, CA199, SF in patients with primary hepatic cancer was significantly higher than that in patients with metastatic liver cancer. Conclusion: With combined determination of these four tumor markers, the detection rate of primary hepatic carcinoma could be enhanced to above 95%. Also, differential diagnosis between primary and metastatic hepatic cancers could be facilitated. (authors)

    Objective: To assess the differential diagnostic value of combined detection of serum CA153, CEA and TPA levels in patients with breast tumor. Methods: Serum levels of CA153, CEA and TPA were measured with RIA in 269 patients with breast tumor and 150 controls. Results: The serum levels of CA153, CEA and TPA in patients with breast cancer were significantly higher than those in the patients with benign breast tumor and controls. The positive rate of CA153 was 63.8% in the patients with breast cancer and that of CEA and TPA was 22.4% and 62.1% respectively, with combined detection of CA153 and CEA, the positive rate was 69.8%, with CA153 and TPA combined, the positive rate was 87.1%, with the three marker combined, the positive rate was 90.5%. The specificity was 77.9% with CA153, 77.9% with CA153 and CEA, 71.9% with CA153 and TPA, and 73.4% with all the three markers combined. Conclusion: The positive rate was increased remarkably with combined detection of CA153, CEA and TPA, however the specificity was not much changed, so the combined detection was valuable for differential diagnosis.

    Full Text Available BACKGROUND: Several studies have suggested that neuron-specific enolase (NSE in serum may be a biomarker of traumatic brain injury. However, whether serum NSE levels correlate with outcomes remains unclear. The purpose of this review was to evaluate the prognostic value of serum NSE protein after traumatic brain injury. METHODS: PubMed and Embase were searched for relevant studies published up to October 2013. Full-text publications on the relationship of NSE to TBI were included if the studies concerned patients with closed head injury, NSE levels in serum after injury, and Glasgow Outcome Scale (GOS or Extended GOS (GOSE scores or mortality. Study design, inclusion criteria, assay, blood sample collection time, NSE cutoff, sensitivity and specificity of NSE for mortality prediction (if sufficient information was provided to calculate these values, and main outcomes were recorded. RESULTS: Sixteen studies were eligible for the current meta-analysis. In the six studies comparing NSE concentrations between TBI patients who died and those who survived, NSE concentrations correlated with mortality (M.D. 0.28, 95% confidence interval (CI, 0.21 to 0.34; I2 55%. In the eight studies evaluating GOS or GOSE, patients with unfavorable outcomes had significantly higher NSE concentrations than those with favorable outcomes (M.D. 0.24, 95% CI, 0.17 to 0.31; I2 64%. From the studies providing sufficient data, the pooled sensitivity and specificity for mortality were 0.79 and 0.50, and 0.72 and 0.66 for unfavorable neurological prognosis, respectively. The areas under the SROC curve (AUC of NSE concentrations were 0.73 (95% CI, 0.66-0.80 for unfavorable outcome and 0.76 (95% CI, 0.62-0.90 for mortality. CONCLUSIONS: Mortality and unfavorable outcome were significantly associated with greater NSE concentrations. In addition, NSE has moderate discriminatory ability to predict mortality and neurological outcome in TBI patients. The optimal discrimination cutoff

    In order to evaluate the value of free prostate specific antigen (FPSA) and F/T PSA ratio in differential diagnosis of benign prostate hyperplasia (BPH) from prostate cancer (PC), serum FPSA and TPSA levels were measured in 85 patients with PC, 97 BPH and 89 healthy volunteers by chemiluminescence enzyme immunoassay (CLEIA), and the ratio of F/T PSA was calculated. The results showed that serum FPSA and TPSA levels were increased in healthy volunteers of 41-88 years old and were significantly higher in healthy volunteers of 61-88 years old than that in 20-40 gear old (P 10.0 μg/L were 65.0%, 30.9% and 4.1%, respectively, while they were 5.9%, 20.0% and 74.1% in PC patients (P<0.01). When the TPSA value was between 4.0-10.0 μg/L and the ratio of F/T PSA was at 0.10 and below, the probability of PC was larger(88.9%). But the ratio of F/T PSA was at 0.25 and above, the probability of PC was smaller(6.20%). Serum FPSA and TPSA both increased with age in healthy volunteers of 41-88 years old and were positively correlated with age. There were about 30.9% of BPH and 20.0% of PC patients with overlapping of TPSA level. Our conclusion is that the F/T PSA ratio can significantly enhance the specificity for PC diagnosis, especially when the TPSA is within the diagnostic gray zone. (authors)

    Neuron-specific enolase (NSE) is a recognized biomarker for the assessment of cerebral injury in neurological disorders. This study aims to report a definitive assessment of the biological variation (BV) components of this biomarker, including within-subject BV (CVI), between-subject BV (CVG), index of individuality (II), and reference change value (RCV), in a cohort of Turkish participants using an experimental protocol. Six blood specimens were collected from each of the 13 apparently healthy volunteers (seven women, six men; ranging in age from 23 to 36) on the same day, every 2 weeks for 2 months. Serum specimens were stored at -20°C until analysis. Neuron-specific enolase levels were evaluated in serum samples using an electrochemiluminescence (ECLIA) immunoassay kit with a Roche Cobas e 411 auto-analyser. ANOVA test was used to calculate the variations. The CVI and CVG for NSE were 21.5% and 28.8%, respectively. Analytical variation (CVA) was calculated as 10.2%. Additionally, II and RCV were calculated as 0.74 and 66% (95% confident interval, CI), respectively. As the performance index (PI) was found to be less than 2 (PI = 0.95), it is concluded that the NSE measurements have a desirable performance for analytical imprecision. Since the II was found to be less than 1 (II: 0.74), the reference values will be of little use.

    To assess which osmolarity equation best predicts directly measured serum/plasma osmolality and whether its use could add value to routine blood test results through screening for dehydration in older people. Diagnostic accuracy study. Older people (≥65 years) in 5 cohorts: Dietary Strategies for Healthy Ageing in Europe (NU-AGE, living in the community), Dehydration Recognition In our Elders (DRIE, living in residential care), Fortes (admitted to acute medical care), Sjöstrand (emergency room) or Pfortmueller cohorts (hospitalised with liver cirrhosis). Directly measured serum/plasma osmolality: current dehydration (serum osmolality>300 mOsm/kg), impending/current dehydration (≥295 mOsm/kg). 39 osmolarity equations calculated using serum indices from the same blood draw as directly measured osmolality. Across 5 cohorts 595 older people were included, of whom 19% were dehydrated (directly measured osmolality>300 mOsm/kg). Of 39 osmolarity equations, 5 showed reasonable agreement with directly measured osmolality and 3 had good predictive accuracy in subgroups with diabetes and poor renal function. Two equations were characterised by narrower limits of agreement, low levels of differential bias and good diagnostic accuracy in receiver operating characteristic plots (areas under the curve>0.8). The best equation was osmolarity=1.86×(Na++K+)+1.15×glucose+urea+14 (all measured in mmol/L). It appeared useful in people aged ≥65 years with and without diabetes, poor renal function, dehydration, in men and women, with a range of ages, health, cognitive and functional status. Some commonly used osmolarity equations work poorly, and should not be used. Given costs and prevalence of dehydration in older people we suggest use of the best formula by pathology laboratories using a cutpoint of 295 mOsm/L (sensitivity 85%, specificity 59%), to report dehydration risk opportunistically when serum glucose, urea and electrolytes are measured for other reasons in

    Full Text Available Background: Sub clinical hyperthyroidism is a state of subnormal serum TSH and T3,T4 within normal range, although usually without overt clinical manifestation but many disastrous complications especially in senile patient. In Iranian people, serum TSH is generally assayed by IRMA method. This study is aimed to determine the value of low serum TSH in these patients, better management and decision when encountered. Materials and Methods: The populations under study are guys with serum TSH lower than 0.5mu/l and normal thyroid hormones without known thyroidal and non-thyroidal illness. A basal serum TSH and TSH 30 minutes after TRH injection intra venous were sampled and correlation of clinical signs and symptoms and basal TSH with sub clinical hyperthyroidism was considered. Results: The population under study was categorized into five groups and prevalence of sub clinical hyperthyroidism was noted. In patients with b.TSH equal or lower than 0.1mu/l, 100%, 0.1-0.2mu/l, 75%, 0.2-0.3mu/l, 38.5%, 0.3-0.4mu/l, 14.3% and TSH levels greater than 0.4mu/l, were all normal. After analyzing of these data and determination of sensitivity and specificity of IRMA, it was concluded that IRMA is not sufficient to distinguish sub clinical hyperthyroidism, although there is a good linear (r=0.68; P<0.001 and cubic (r=0.79; P<0.001 relationship between b.TSH and d.TSH. Conclusion: Since TRH test is not cost effective for all cases, TSH levels lower than 0.25mu/l, can be considered as sub clinical hyperthyroidism and levels more than 0.4mu/l, as normal. In cases with TSH level between 0.25 and 0.4mu/l, TRH test is needed in high-risk patients.

    The 2009 CCQM-K80 'Comparison of value-assigned CRMs and PT materials: creatinine in human serum' is the first in a series of key comparisons directly testing the chemical measurement services provided to customers by National Metrology Institutes (NMIs) and Designated Institutes. CCQM-K80 compared the assigned serum creatinine values of certified reference materials (CRMs) using measurements made on these materials under repeatability conditions. Six NMIs submitted 17 CRM materials for evaluation, all intended for sale to customers. These materials represent nearly all of the higher-order CRMs then available for this clinically important measurand. The certified creatinine mass fraction in the materials ranged from 3 mg/kg to 57 mg/kg. All materials were stored and prepared according the specifications provided by each NMI. Samples were processed and analyzed under repeatability conditions by one analyst using isotope dilution liquid chromatography-mass spectrometry. The instrumental repeatability imprecision, expressed as a percent relative standard deviation, was 1.2%. Given the number of materials and the time required for each analysis, the measurements were made in two measurement campaigns ('runs'). In both campaigns, replicate analyses (two injections of one preparation separated in time) were made on each of two or three independently prepared aliquots from one randomly selected unit of each of the 17 materials. The mean value, between-campaign, between-aliquot and between-replicate variance components, standard uncertainty of the mean value, and the number of degrees of freedom associated with the standard uncertainty were estimated using a linear mixed model. Since several of the uncertainties estimated using this traditional frequentist approach were associated with a single degree of freedom, Markov Chain Monte Carlo Bayesian analysis was used to estimate 95% level-of-confidence coverage intervals, U95.

    OBJECTIVE: Recent evidence suggests that high cortisol concentrations are associated with increased morbidity and mortality in very low birth weight (VLBW) infants. Neonatal illness severity and mortality risk scores are reliable in predicting morbidity and mortality. The objectives were (i) to assess the correlation between serum cortisol levels and clinical assessment of multi-organ dysfunction\\/illness severity scores (CRIB II, SNAPPE-II and neonatal multiple organ dysfunction score (NEOMOD)) in first 24 h in VLBW infants and (ii) to assess the relationship between surrogates of end organ blood flow and serum cortisol levels. STUDY DESIGN: A prospective observational cohort study. Neonates with birth weight <1500 g were eligible for enrollment. Echocardiography evaluation of superior vena cava (SVC) flow was carried out in the first 24 h life. Cortisol levels were measured simultaneously and appropriate clinical scores were calculated. RESULT: A total of 54 VLBW neonates were enrolled following parental consent. Two patients were excluded because of congenital malformations. In 14 babies the cortisol value was not simultaneously obtained. The mean birth weight was 1.08 kg, mean gestational age was 27.8 weeks. There was a significant correlation between cortisol and NEOMOD score (P=0.006). There was no correlation between cortisol and CRIB II score (P=0.34), SVC flow (P=0.49) and mean arterial blood pressure respectively (P=0.35). CONCLUSION: There was no correlation between SVC flow and cortisol values or between cortisol and mean blood pressure values. There was a significant correlation between cortisol levels and neonatal organ dysfunction score evaluated suggesting that stressed VLBW infants do mount a cortisol response.

    To explore the diagnostic value of measuring the level of ferritin in pleural and peritoneal effusion for differentiating exudates from transudates, 128 effusion samples were initially detected for differentiating exudates from transudates by traditional method and Light's criteria. Ferritin in the effusions and serum ferritin were detected simultaneously, and the ratio of effusion ferritin (P Ft ) to serum ferritin (S Ft ) was counted. Based on the clinical data, the samples were divided into four groups and P Ft and P Ft /S Ft were compared. At the same time, the sensitivity and specificity of P Ft and P Ft /S Ft in differentiating exudates from transudates were compared with traditional method and Light's criteria. The results showed that in the groups of tuberculous pleurisy, non-tuberculous, benign pleurisy, and malignant tumor, the concentration of Ft in the effusions was significantly higher than that in the group of congestive heart failure and cirrhosis; and the Ft in exudates was significantly higher than that in transudates (P 0.05). If the cut-off value was set up for Ft in the effusion as 100 μg/L and P Ft /S Ft ratio as 0.5, respectively, the differentiating sensitivity and specificity were 94.2% and 87.0%, respectively. Conclusion was that the concentration of P Ft and P Ft /S Ft in exudates are higher than 100 μg/L and 0.5, respectively. On the contrary, they are lower than the cut-off level in transudates. P Ft and P Ft /S Ft have high sensitivity and high specificity in differentiating exudates from transudates, and have great diagnostic value

    Objective: To investigate the diagnostic value of determination of serum and ascitic fluid AFP, CEA and CA125 contents for differentiating benign from malignant ascites. Methods: Serum and ascitic fluid contents of the three tumor markers were measured with RIA in 86 patients with ascites due to various causes. Results: The serum and ascitic fluid AFP, CEA and CA125 levels in patients with malignant ascites were very significantly higher than those in patients with benign ascites (p<0.01). For differentiation of benign (mainly T.B and liver cirrhosis) from malignant ascites, CA125≥500 IU/ml and AFP≥300 ng/ml could be taken as the critical value with high specificity and accuracy. Conclusion: Determinations of the three tumor markers levels in serum and ascitic fluid were of high value for differential diagnosis of the etiology of ascites

    The purpose of this study was to evaluate if short-term serum thyroglobulin (Tg) elevation after radioiodine administration can predict successful radioiodine remnant ablation (RRA) and whether comparable RRA effectiveness is exhibited between a group administered with recombinant human thyrotropin (rhTSH) and a group experiencing thyroid hormone withdrawal (THW), in preparation for RRA. A retrospective chart review was performed on 39 patients in the rhTSH group and 46 patients in the THW group. They were treated for differentiated thyroid carcinoma by total or near total thyroidectomy, and referred for RRA between 2003 and 2006 (the rhTSH group) and between January and June of 2006 (the THW group). They were assessed for serum Tg levels just before I-131 administration (TgD0), reassessed 9 days later (TgD9), and again 6-12 months later. RRA was successful in 64 (37 from the THW group and 27 from the rhTSH group) of the total 85 patients. The success rates of RRA had no statistically significant differences between the two groups. In both groups, TgD9/TgD0 values were significantly higher in the RRA success group (the rhTSH group; P=0.03, the THW group; P=0.04). By combining cutoff values of TgD0 and TgD9/TgD0, the successful RRA value was determined to be 96.7% (29/30) with TgD0≤5.28 ng/mL and TgD9/TgD0>4.37 in both groups (the rhTSH group; 100% (16/16), the THW group; 92.9% (13/14)). Using logistic multivariate analysis, only TgD0 was independently associated with successful RRA. We may predict successful ablation by evaluating short-term serum Tg elevation after I-131 administration for RRA, in both rhTSH and THW patients

    Full Text Available BACKGROUND: Mutant p53 protein over-expression has been reported to induce serum antibodies against p53. We assessed the diagnostic precision of serum p53 (s-p53 antibodies for diagnosis of cancer patients and compared the positive rates of the s-p53 antibody in different types of cancers. METHODS: We systematically searched PubMed and Embase, through May 31, 2012. Studies were assessed for quality using QUADAS (quality assessment of studies of diagnostic accuracy. The positive likelihood ratio (PLR and negative likelihood ratio (NLR were pooled separately and compared with overall accuracy measures using diagnostic odds ratios (DORs and Area under the curve(AUC. Meta regression and subgroup analyses were done, and heterogeneity and publication bias were assessed. RESULTS: Of 1089 studies initially identified, 100 eligible studies with 23 different types of tumor met the inclusion criteria for the meta-analysis (cases = 15953, controls = 8694. However, we could conduct independent meta analysis on only 13 of 36 types of tumors. Approximately 56% (56/100 of the included studies were of high quality (QUADAS score≥8. The summary estimates for quantitative analysis of serum p53 antibody in the diagnosis of cancers were: PLR 5.75 (95% CI: 4.60-7.19, NLR 0.81 (95%CI: 0.79-0.83 and DOR 7.56 (95% CI: 6.02-9.50. However, for the 13 types of cancers on which meta-analysis was conducted, the ranges for PLR (2.33-11.05, NLR (0.74-0.97, DOR (2.86-13.80, AUC(0.29-0.81, and positive rate (4.47%-28.36% indicated significant heterogeneity. We found that breast, colorectal, esophageal, gastric, hepatic, lymphoma, lung and ovarian cancer had relatively reasonable diagnostic accuracy. The remaining results of the five types of cancers suggested that s-p53 antibody had limited value. CONCLUSIONS: The current evidence suggests that s-p53 antibody has potential diagnostic value for cancer, especially for breast, colorectal, esophageal, gastric, hepatic

    There is a correlation between both serum hemoglobin (HGB) and hematocrit (HCT) and attenuation values of vessels in noncontrast-enhanced computed tomography (NECT), which could influence calculated perfusion maps in CT perfusion. We retrospectively included 45 patients, who presented with acute new neurological symptoms and underwent NECT and CT perfusion (128-row multi detector scanner, coverage: 6.9 cm craniocaudally; 80 kV; 200 mAs; temporal resolution: 2 seconds using 40 mL Ultravist 370 at a flow rate of 5 mL/s) on admission and a follow-up MRI within 1 week of admission. Hematocrit, HGB, and attenuation values did not differ between patients with stroke and controls. A statistically significant correlation was found between HCT and HGB and attenuation values in the internal carotid artery or middle cerebral artery on NECT (P Hematocrit and HGB do not influence calculated perfusion maps. There is no need for HCT/HGB-adjusted cerebral blood volume thresholds in stroke patients.

    To examine the predictive value of tumor markers for evaluating tumor resectability in patients with hilar cholangiocarcinoma and to explore the prognostic effect of various preoperative factors on resectability in patients with potentially resectable tumors. Patients with potentially resectable tumors judged by radiologic examination were included. The receiver operating characteristic (ROC) analysis was conducted to evaluate serum carbohydrate antigenic determinant 19-9 (CA 19-9), carbohydrate antigen 125 (CA 125) and carcino embryonie antigen levels on tumor resectability. Univariate and multivariate logistic regression models were also conducted to analysis the correlation of preoperative factors with resectability. In patients with normal bilirubin levels, ROC curve analysis calculated the ideal CA 19-9 cut-off value of 203.96 U/ml in prediction of resectability, with a sensitivity of 83.7 %, specificity of 80 %, positive predictive value of 91.1 % and negative predictive value of 66.7 %. Meanwhile, the optimal cut-off value for CA 125 to predict resectability was 25.905 U/ml (sensitivity, 78.6 %; specificity, 67.5 %). In a multivariate logistic regression model, tumor size ≤3 cm (OR 4.149, 95 % CI 1.326-12.981, P = 0.015), preoperative CA 19-9 level ≤200 U/ml (OR 20.324, 95 % CI 6.509-63.467, P hilar cholangiocarcinoma. Preoperative CA 19-9 and CA 125 levels predict resectability in patients with radiological resectable hilar cholangiocarcinoma. Increased preoperative CA 19-9 levels and CA 125 levels are associated with poor resectability rate.

    The present study aimed to investigate the clinical value of serum anti-mullerian hormone (AMH) and inhibin B (INHB) in predicting the ovarian response of patients with polycystic ovary syndrome (PCOS). A total of 120 PCOS patients were enrolled and divided into three groups in terms of the ovarian response: a low-response group (n=36), a normal-response group (n=44), and a high-response group (n=40). The serum AMH and INHB levels were measured by enzyme-linked immunosorbent assay (ELISA). The follicle stimulating hormone (FSH), luteinizing hormone (LH), and estradiol (E2) levels were determined by chemiluminescence microparticle immunoassay. The correlation of the serum AMH and INHB levels with other indicators was analyzed. A receiver operating characteristic (ROC) curve was established to analyze the prediction of ovarian response by AMH and INHB. The results showed that there were significant differences in age, body mass index (BMI), FSH, total gonadotropin-releasing hormone (GnRH), LH, E2, and antral follicle counts (AFCs) between the groups (Povarian response of PCOS patients increasing (Povarian response showed that the area under the ROC curve (AUC) value of the serum AMH level was 0.817, with a cut-off value of 1.29 ng/mL. The sensitivity and specificity were 71.2% and 79.6%, respectively. The AUC value of serum INHB was 0.674, with a cut-off value of 38.65 ng/mL, and the sensitivity and specificity were 50.7% and 74.5%, respectively. ROC curve analysis showed when the serum AMH and INHB levels were used to predict a high ovarian response, the AUC value of the serum AMH level was 0.742, with a cut-off value of 2.84 ng/mL, and the sensitivity and specificity were 72.7% and 65.9%, respectively; the AUC value of the serum INHB level was 0.551 with a cut-off of 45.76 ng/mL, and the sensitivity and specificity were 76.3% and 40.2%, respectively. It was suggested the serum AMH and INHB levels have high clinical value in predicting the ovarian response of PCOS

    Objective: To assess the value of immunoglobulin heavy/light chain (HLC) immunoassay on therapeutic response in patients with multiple myeloma(MM). Methods: A total of 45 newly diagnosed MM patients were retrospectively enrolled in Peking Union Medical College Hospital from 2013 to 2016, whose 115 serum samples were consecutively collected. HLC was tested to evaluate response and compare with other methods for M protein detection. Results: ①There were 30 males and 15 females in total of whom the monoclonal immunoglobulin was IgG in 27 (IgGκ∶IgGλ 12∶15) and IgA (IgAκ∶IgAλ 9∶9) in 18. The arerage age of the studied population was 59 (range 43-80) . ② In 34 patients with serum sample at diagnosis, 32 (94.1%) had abnormal HLC ratio (rHLC) while 2 patients with IgG had normal rHLC. The percentages of abnormal rHLC was 81.8% (18/22) at partial response、50.0%(9/18) at very good complete response and 16.0%(4/25) at complete response. ③In 25 patients reaching CR, there were 13 with IgG and 12 with IgA. 4 patients equally split of IgG and IgA had abnormal rHLC at complete response. ④By monitoring the rHLC of some patients consecutively, we found that the remission of rHLC was to some extent behind the remission of SPE and IEF, or even rFLC. Conclusion: Immunoglobulin HLC detection is one feasible method for minimal residual disease detection.

    Obesity is a global disease, affecting nearly half a billion people. Unfortunately, this trend is mirrored in our canine population. As obesity is a complex inflammatory disease, there is a need to determine whether routine medical screening tests may indicate, or be influenced by, its presence. The objective of the current study was to determine if significant differences exist between CBC and biochemical profile values from control vs overweight/obese, client-owned dogs considered clinically healthy. Dogs presented for routine health examinations, including minor dental or elective surgical procedures, were retrospectively identified from a hospital population. Animals were allocated to 2 categories based on body condition score (BCS), and data were analyzed by Mann-Whitney nonparametric analysis with statistical significance at a P ≤ .05. After exclusions, 116 dogs were assigned to the overweight/obese group (BCS ≥ 7) and 240 dogs to the control group (BCS = 4-6). Overweight/obese dogs had higher total leukocyte counts and higher plasma protein and globulin concentrations. Other differences were attributed to decreased serum water fraction (increased sodium, albumin, calcium, and anion gap) in the overweight/obese group. Interestingly, chloride concentration was decreased (in the face of increased sodium) in the obese group. There is CBC and biochemical evidence to support the concern that obesity influences laboratory values, even in dogs considered clinically healthy. Prospective studies aimed at characterizing these changes are needed to provide insight into the connection between obesity and its comorbidities. © 2017 American Society for Veterinary Clinical Pathology.

    Recombinant human TSH (rhTSH) is used to increase radioiodine uptake during imaging of thyroid cancer, obviating the need to render the patient hypothyroid. We assessed the reproducibility of radioiodine uptake, serum thyrotropin (TSH), and stimulated serum thyroglobulin (Tg) levels after rhTSH administration. A retrospective review was performed of patients at Stanford who underwent whole-body {sup 131}I scanning for surveillance of thyroid cancer twice after thyroidectomy and {sup 131}I ablation, with rhTSH prior to each scan. Forty-eight hour radioiodine uptake, peak serum TSH, and stimulated serum Tg levels for each study were recorded. Paired t tests and correlation analysis were used to assess interexamination repeatability. Twenty-three patients underwent two scintiscans with rhTSH, for a total of 46 exams. There was no significant difference between percent uptake at 48 h in the paired exams (p=0.40). Serum TSH level was measured in 45 of 46 exams; TSH exceeded 50 mIU/l in all cases, and there was no significant difference between paired TSH levels (p=0.93). All patients had stimulated serum Tg levels measured, with no significant difference between paired Tg levels (p=0.40); after excluding one patient whose Tg changed from 15.8 ng/ml to undetectable between scans without interval treatment, the p value rose to 0.95. There was a strong correlation among paired uptake values (r=0.85, p<0.0001), peak serum TSH (r=0.69, p=0.0003), and stimulated Tg levels (r=0.81, p<0.0001). No discordant scan interpretations were reported. Forty-eight hour radioiodine uptake, peak serum TSH, and stimulated serum Tg levels after administration of rhTSH are repeatable between studies, demonstrating reproducibility of diagnostic results without rendering patients hypothyroid.

    Full Text Available Introduction: Neonatal sepsis is the most common cause of death in newborns in developing countries. Prompt diagnosis is the critical determinant in its outcome. As manifestations are often vague, clinically it is difficult to differentiate sepsis from non-infective conditions. Timely diagnosis is important as delay in initiation of antimicrobials can prove fatal. On the other hand empirical use of antibiotics not only increases the risk of antibiotic resistance but also delays the diagnosis of true condition. Procalcitonin (PCT has been well evaluated in late onset sepsis but data pertaining to Early Onset Sepsis (EOS are still lacking. We compared the diagnostic value of PCT and CRP (C-Reactive Protein in EOS. Aim: To compare the diagnostic value of serum PCT and CRP in early onset sepsis. Materials and Methods: It was a prospective observational study conducted in Neonatal Intensive Care Unit of the Department of Paediatrics, Dr.S.N. Medical College, Jodhpur, India. All neonates delivered in hospitals attached to this medical college or referred here within 7 days of life and having ≥2 perinatal risk factors for sepsis or displaying clinical sepsis were included in the study. All enrolled neonates were subjected to sepsis screen, PCT levels and blood culture at birth or admission which ever was the earliest. PCT levels ≥ 0.5 ng/ml and CRP levels above 8mg/l were considered positive for EOS. Results: Sensitivity and negative predictive value of PCT were higher than CRP (90.12% vs. 50.62% and 93.33% vs. 79.06% respectively. Also it had a higher positive predictive value of 40.56% than CRP where it was 37.61%. CRP was more specific (68.95% vs. 51.4% with overall higher diagnostic accuracy (0.64 vs. 0.61 in comparison to PCT. Conclusion: PCT is more sensitive and has a higher negative predictive value than CRP in early onset sepsis. Higher positive predictive value and specificity of CRP suggest that, PCT should not be used alone rather

    Objective: To explore the clinical diagnostic value of combined determination of serum TSGF, CEA, CYFRA21-1 and NSE levels in patients with lung cancer. Methods: The four serum tumor markers were determined with RIA or other methods in 179 patients with lung cancer, 48 patients with benign lung diseases and 51 controls. Results: The serum levels of all these four markers in the cancer patients were significantly higher (P<0.05-P<0.01) than those in patients with benign pulmonary disorders with the exception of: (1) Serum TSGF, CEA and NSE levels in patients with stage I and II squamous cell carcinoma (n=37) and (2) serum NSE levels in patients with stage I and II adenocarcinoma (n=32). As a whole, the levels of the markers increased along with the increase of the severity of the disease. Conclusion: For the early diagnosis of lung cancer, serum CYFRA21-1 levels determination is the most specific and serum NSE levels determination for diagnosis in patients with NSCLC is the least sensitive. The combined determination of tumor markers is the best choice. (authors)

    IgG4-related disease (IgG4-RD) is a novel disease entity that includes Mikulicz's disease, autoimmune pancreatitis (AIP), and many other conditions. It is characterized by elevated serum IgG4 levels and abundant IgG4-bearing plasmacyte infiltration of involved organs. We postulated that high levels of serum IgG4 would comprise a useful diagnostic tool, but little information is available about IgG4 in conditions other than IgG4-RD, including rheumatic diseases. Several reports have described cutoff values for serum IgG4 when diagnosing IgG4-RD, but these studies mostly used 135 mg/dL in AIP to differentiate from pancreatic cancer instead of rheumatic and other common diseases. There is no evidence for a cutoff serum IgG4 level of 135 mg/dL for rheumatic diseases and common diseases that are often complicated with rheumatic diseases. The aim of this work was to re-evaluate the usual cutoff serum IgG4 value in AIP (135 mg/dL) that is used to diagnose whole IgG4-RD in the setting of a rheumatic clinic by measuring serum IgG4 levels in IgG4-RD and various disorders. We therefore constructed ROC curves of serum IgG4 levels in 418 patients who attended Sapporo Medical University Hospital due to IgG4-RD and various rheumatic and common disorders. The optimal cut-off value of serum IgG4 for a diagnosis of IgG4-RD was 144 mg/dL, and the sensitivity and specificity were 95.10 and 90.76%, respectively. Levels of serum IgG4 were elevated in IgG4-RD, Churg-Strauss syndrome, multicentric Castleman's disease, eosinophilic disorders, and in some patients with rheumatoid arthritis, systemic sclerosis, chronic hepatitis, and liver cirrhosis. The usual cut-off value of 135 mg/dL in AIP is useful for diagnosing whole IgG4-RD, but high levels of serum IgG4 are sometimes observed in not only IgG4-RD but also other rheumatic and common diseases.

    Prostatic enlargement is a common cause of bladder outlet obstruction in men in Nigeria. Malignant enlargements must be differentiated from benign enlargements for adequate treatment of each patient. High serum total prostate-specific antigen (tPSA) levels suggest malignancy, but some of the biopsies done due to a serum tPSA value >4 ng/mL would be negative for malignancy because of the low specificity of tPSA for prostate cancer. This study aims to compare the histologic findings of all prostate specimens obtained from core needle biopsy, open simple prostatectomy, and transurethral resection of the prostate with the respective serum tPSA values in an attempt to decipher the role of serum tPSA in the management of these patients. The case notes of patients attended to from April 2009 to March 2012 were analyzed. Essentially, the age of the patient, findings on digital rectal examination, abdominopelvic ultrasonography report on the prostate, serum tPSA, and histology reports from biopsy or prostatectomy specimens as indicated were extracted for analysis. The relationship between age, findings on digital rectal examination, serum tPSA, abdominopelvic ultrasonography report, and histology are compared. A statistically significant relationship existed between a malignant histology and age 65 years and older, suspicious findings on digital rectal examination, suspicious ultrasonography findings, and serum tPSA >10 ng/mL, but not tPSA >4 ng/mL. In Nigerian patients with symptomatic prostate enlargement, serum tPSA should be seen as a continuum with increasing risk of prostate malignancy.

    To explore the clinical value of determination of serum troponin I (cTnI) and hyper-sensitive C-reactive protein(hs-CRP) around extracorporeal circulation, cTnI and hs-CRP were determined in 46 patients with congenital heart disease before and after the surgery (0, 24h, 3d, 7d, 15d respectively). At the same time, electrocardiogram(ECG), hemo dynamics and other adverse events were recorded. Before the surgery results of cTnI and hs-CRP were in nor- mal range, wheraas after surgery the level of cTnI went up, reached its peak at 24h, and returned normal on d7. The level of hs-CRP begin to increase at 24h, returned normal on dT. Its level was higher in patients with postoperative infection than that in patients without infection, however, it returned normal after anti-inflammatory treatment. Therefore, cTnI and hs-CRP may be taken as diagnostic criteria of prognosis in patient after extracorporea circulation surgery. Postoperative infection around extracorporeal circulation surgery could be prevented by monitring hs-CRP concentration. (authors)

    Aims The ratio of aspartate aminotransferase (AST) to alanine aminotransferase (ALT) is of great interest as a possible novel marker of metabolic syndrome. However, longitudinal studies emphasizing the incremental predictive value of the AST-to-ALT ratio in diagnosing individuals at higher risk of developing metabolic syndrome are very scarce. Therefore, our study aimed to evaluate the AST-to-ALT ratio as an incremental predictor of new onset metabolic syndrome in a population-based cohort study. Material and Methods The population-based cohort study included 2276 adults (903 men and 1373 women) aged 40–70 years, who participated from 2005–2008 (baseline) without metabolic syndrome and were followed up from 2008–2011. Metabolic syndrome was defined according to the harmonized definition of metabolic syndrome. Serum concentrations of AST and ALT were determined by enzymatic methods. Results During an average follow-up period of 2.6-years, 395 individuals (17.4%) developed metabolic syndrome. In a multivariable adjusted model, the odds ratio (95% confidence interval) for new onset of metabolic syndrome, comparing the fourth quartile to the first quartile of the AST-to-ALT ratio, was 0.598 (0.422–0.853). The AST-to-ALT ratio also improved the area under the receiver operating characteristic curve (AUC) for predicting new cases of metabolic syndrome (0.715 vs. 0.732, P = 0.004). The net reclassification improvement of prediction models including the AST-to-ALT ratio was 0.23 (95% CI: 0.124–0.337, Pmetabolic syndrome and had incremental predictive value for incident metabolic syndrome.

    Full Text Available Objective: To evaluate the utility of entheseal ultrasonography and serum COMP in the preclinical diagnosis of psoriatic arthritis. Methods: 60 psoriatic patients were divided into: 30 patients with psoriasis (group I and 30 patients with psoriatic arthritis as control (group II. They underwent independent clinical and ultrasonographic examination of both lower limbs at the calcaneal insertions of Achilles tendons. Psoriatic arthritis disease activity and severity was assessed by modified DAS28 and Steinbrockers scores. Serum levels of COMP were measured for all patients by ELISA. Results: On clinical examination, no entheseal abnormalities were detected in group I while they were present in 23.3% of group II with statistically significant difference between them (P 0.05. Serum COMP were significantly elevated in group I and II with no statistically significant difference between them (mean ± SD 5.9 ± 3 and 6.8 ± 12 respectively, P > 0.05. Entheseal ultrasound was more specific (67% while serum COMP was more sensitive (87% in the preclinical diagnosis of psoriatic arthritis. Serum COMP levels were significantly correlated with CRP in both groups and with DAS28 and Steinbrockers scores in group II (P < 0.01. Conclusion: Entheseal ultrasonography and serum COMP levels may be used complementary to each other for preclinical diagnosis of psoriatic arthritis. Serum COMP seems to be promising prognostic marker for psoriatic arthritis patients.

    This study was performed to better know diagnosis associated with serum IgG4 concentration, and to explore the possibility for development of a serum IgG4 for IgG4-related disease (IgG4-RD) in Chinese populations. We studied retrospectively 497 IgG4 serum subclass measurements from Peking Union Medical College Hospital during the four-year period, including 242 IgG4-RD, 130 other diseases and 125 healthy individuals. Serum IgG4 concentrations were significantly higher in IgG4-RD than in other pathologies (1662.9 ± 3760.9 mg/L, p IgG4 level between other pathologies group and healthy individuals (p = 0.075). Among the 242 IgG4-RD patients analyzed, serum IgG4 concentrations were normal in 46 patients (19.0%). We found 32 patients (24.6%) with elevated serum IgG4 levels among the 130 patients who suffered from other pathologies. There were seven (5.6%) with serum IgG4 over 1350 mg/L in healthy individuals. The ROC curve analysis revealed that the optimal sensitivity and specificity were 80.0% and 88.2%, respectively, at the concentration of 1575 mg/L for Chinese patients. Our study demonstrated that serum IgG4 elevation was not specific of IgG4-RD. Further studies are needed to define the sensibility and specificity of IgG4 values for the diagnosis of IgG4-RD.

    Serum soluble corin has been suggested to be associated with hyperglycemia by cross-sectional study. However, the prospective relationship between them remains unclear, and whether lipid component influences the relationship between them has not yet been studied. A total of 1961 participants who were free from hyperglycemia were enrolled at baseline in 2010. The serum soluble corin concentrations were measured at baseline and all participants were followed up for hyperglycemia in 2014. The association between serum soluble corin and hyperglycemia incidence was appreciably modified by high density lipoprotein cholesterol (HDL-C) (P interaction  = 0.04). Elevated serum soluble corin was associated with the risk of hyperglycemia only in the HDL-C ≥1.04 mmol/l subgroup rather than all participants. In participants with HDL-C ≥1.04 mmol/l, the adjusted odds ratio (95% CU) of hyperglycemia associated with the fourth quartiles of corin was 1.78 (1.08-2.94) compared with the lowest quartile of serum soluble corin, and there was a positive linear dose-response relationship between them (P for linearity <0.01). The ordinal analysis showed an association between serum soluble corin and hyperglycemia severity (adjusted OR, 1.81; 95% CI, 1.10-2.99; P trend  = 0.02, when 2 extreme quartiles were compared). The addition of serum soluble corin to conventional risk factors improved risk prediction for hyperglycemia (net reclassification index: 0.16; integrated discrimination improvement: 0.01) in participants with HDL-C ≥1.04 mmol/l. Serum soluble corin might be a valuable biomarker in prediction of future hyperglycemia in population with HDL-C ≥1.04 mmol/l, suggesting that corin might play a potential role in glucose metabolism.

    To determine the predictive value of serum uric acid for preeclampsia, its severity and pregnancy outcome. This is a cohort study that was performed on normal pregnant women attending antenatal clinic at Nnamdi Azikiwe University Teaching Hospital Nnewi Nigeria. Serum uric acid was determined in 200 women attending antenatal clinic between the gestational ages of 14 and 26 weeks. The women were followed up at 2 weekly intervals until 36 weeks and weekly thereafter until delivery. Women who developed pre-eclampsia or eclampsia were identified. Pregnancy outcomes were determined as well as fetal and placental weights. The data was analised with SPSS version 16.0. The chi square was used for test of significance. The positive and negative predictive values were determined. A total of 200 normal pregnant women were recruited for the study. Nine of them were lost to follow up. Subsequently, 10.5% of the women developed preeclampsia. The positive and negative predictive values of serum uric acid for preeclampsia were 78.9% and 97.1%, respectively. Serum uric acid was found to be a useful predictor of the occurrence of preeclampsia and its severity.

Methods: Serum tPSA, cPSA (with CLIA) and IGF-I (with IRMA) levels were determined in 41 patients with prostatic carcinoma, 60 patients with benign prosta- tic hypertrophy (BPH) and 55 controls. Results: The serum tPSA, cPSA and IGF-I levels in patients with prostatic cancer were significantly higher than those in patients with BPH and controls (P<0.01). Taking the cut-off values of 4ng/ml, 3.6ng/ml and 150 for tPSA, cPSA and IGF-I respectively, the combined determination of these three items would yield a sensitivity of 88.6%, specificity of 84.9%, positive predicative value of 83% and negative predicative value of 90.0% for diagnosis of prostatic cancer. Conclusion: Combined determination of tPSA, cPSA and IGF-I would yield better sensitive and accurate diagnostic rate in patients with prostatic cancer, especially in those with laboratory values within the 'grey zone'.

    Full Text Available Background. After initial treatment of breast cancer (BC, monitoring locoregional recurrence and distant metastases is a great clinical challenge. Objective. To evaluate the efficacy of PET/CT in association with serum tumor makers in BC follow-up. Methods. Twenty-six women with a history of modified radical mastectomy were evaluated by 18F-FDG PET/CT. The results of PET/CT were compared with those of conventional imaging techniques (CITs (including mammography, chest radiography, CT, MRI, ultrasound, and bone scintigraphy. Serum tumor markers of CEA, CA 125, and CA 15-3 in the BC patients were also analyzed in association with the results of PET/CT. Results. Compared with CITs, PET/CT was more sensitive to detect the malignant foci and had better patient-based sensitivity and specificity. The mean CA 15-3 serum level was significantly higher in the confirmed positive patients of PET/CT results than in the confirmed negative ones, while there were no significant differences in the serum levels of CEA and CA 125 of both groups. Conclusion. PET/CT is a highly efficient tool for BC follow-up compared with CITs. The high serum levels of CA 15-3 in confirmed positive PET/CT patients indicated the clinical value of CA 15-3 in BC follow-up.

    To determine the application value of four serum tumor markers sTn, CA242, CA 19-9 and CEA in the diagnosis of gastroenterological neoplasm, the serum sTn, CA242, CA19-9 and CEA in 30 normal adult controls and 60 patients with gastroenterological neoplasm were measured by IRMA. The results showed that the serum sTn, CA242, CA19-9 and CEA levels in patients with gastric carcinoma or colorectal carcinoma were much higher than those in control group (P<0.01). The serum CEA, CA19-9 and CA242 levels in patients with colorectal carcinoma were significantly higher than those in patients with gastric carcinoma (P<0.01), but the serum sTn level in the former was markedly lower (P<0.01) than that in the latter. The sensitivity of tumor marker increased with the progress of clinical stages, with a considerably higher sensitivity for stage IV compared with stage I-II (P<0.01). The combined test of four tumor markers could be more sensitive than single test in detecting gastric carcinoma and colorectal carcinoma (P<0.05). Four tumor markers are useful for diagnosing gastroenterological neoplasm, and the combined measurement of 4 tumor markers could increase the sensitivity of detecting gastric carcinoma. (authors)

    Objective: To investigate the diagnostic values of combined determination of serum CA125, CA199 and SIL-2R levels in patients with endometriosis. Methods: Serum CA125, CA199 were measured with RIA and SIL-2R levels with ELISA in 54 patients with endometriosis and 35 controls. Results: The serum levels of CA125, CA199 and SIL-2R in patients with endometriosis were significantly higher than those in controls (P<0.01). The sensitivity and speciality of CA125 for endometriosis was 70.2% and 80.4% respectively, the sensitivity and speciality of CA199 for endometriosis was 62.4% and 71.8% respectively, the sensitivity and speciality of SIL-2R was 89.5% and 60.2% respectively. The sensitivity of the combined determination of CA125, CA199 and SIL-2R for endometriosis was 86.8% being significantly higher than that of CA125 and CA199 respectively. Conclusion: Combined determination of the serum CA125, CA199 and SIL-2R levels in serum can increase the diagnostic sensitivity for endometriosis. (authors)

  16. Predictive value of uterine contractility and the serum levels of progesterone and oestrogens with regard to preterm labour.

    1984-01-01

    A longitudinal investigation regarding the serum concentrations of oestradiol, oestriol and progesterone in relation to uterine activity has been performed in 80 healthy primigravid women during the course of pregnancy up to the 37th week of pregnancy. The frequency of uterine contractions was quantitatively objectivated by means of external toco-dynamometry; simultaneously the uterine activity has been recorded by the pregnant women qualitatively. It appears that there is a gradual increase of all the three mentioned hormones during the course of pregnancy. However, there is a large interindividual spread. There exists no relation between the hormonal serum levels and uterine activity (quantitatively as well as qualitatively recorded). Between these two latter there is a poor relation. It is impossible to predict the occurrence of preterm birth based on hormonal serum changes. This holds for the progesterone-oestradiol ratio.

    Objective: To explore the diagnostic value of determination of changes of serum CA125 and CA19-9 levels in patients with endometriosis. Methods: Serum CA125 and CA19-9 levels were determined with RIA in 45 patients with endometriosis and 40 controls. Results: Serum levels of CA125 and CA19-9 in patients with endometriosis (89.63 ± 30.16u/ml and 95.62±43.67u/ml respectively) were significantly higher than those (16.26±6.37u/ml and 20.26±8.25u/ml respectively) in controls (P<0. 001). Sensitivity of CA125 for diagnosis of endometriosis was 77.78% and that of CA19-9 was 62.22%, while the specificity was 92.50% and 90.00% respectively. If we only took the patients with both markers elevated as being diagnostically positive, the sensitivity would naturally be lower (57.78%) but the specificity would be 100%. Levels of the markers were significantly higher in stage III, IV patients than those in patients with stage I, II disease (P<0.01). Conclusion: Combined determination of serum CA125 and CA19-9 levels were of highly specific diagnostic value in patients with endometriosis. (authors)

    Full Text Available David G Levitt,1,* Michael D Levitt2,* 1Department of Integrative Biology and Physiology, University of Minnesota, 2Research Service, Veterans Affairs Medical Center, Minneapolis, MN, USA *These authors contributed equally to this work Abstract: Serum albumin concentration (CP is a remarkably strong prognostic indicator of morbidity and mortality in both sick and seemingly healthy subjects. Surprisingly, the specifics of the pathophysiology underlying the relationship between CP and ill-health are poorly understood. This review provides a summary that is not previously available in the literature, concerning how synthesis, catabolism, and renal and gastrointestinal clearance of albumin interact to bring about albumin homeostasis, with a focus on the clinical factors that influence this homeostasis. In normal humans, the albumin turnover time of about 25 days reflects a liver albumin synthesis rate of about 10.5 g/day balanced by renal (≈6%, gastrointestinal (≈10%, and catabolic (≈84% clearances. The acute development of hypoalbuminemia with sepsis or trauma results from increased albumin capillary permeability leading to redistribution of albumin from the vascular to interstitial space. The best understood mechanism of chronic hypoalbuminemia is the decreased albumin synthesis observed in liver disease. Decreased albumin production also accounts for hypoalbuminemia observed with a low-protein and normal caloric diet. However, a calorie- and protein-deficient diet does not reduce albumin synthesis and is not associated with hypoalbuminemia, and CP is not a useful marker of malnutrition. In most disease states other than liver disease, albumin synthesis is normal or increased, and hypoalbuminemia reflects an enhanced rate of albumin turnover resulting either from an increased rate of catabolism (a poorly understood phenomenon or enhanced loss of albumin into the urine (nephrosis or intestine (protein-losing enteropathy. The latter may occur

    Epstein-Barr virus (EBV) is closely associated with nasopharyngeal carcinoma (NPC). Serum IgA antibodies against early antigen (EA-IgA) and viral capsid antigen (VCA-IgA) are the most commonly used to screen for NPC in endemic areas. However, the prognostic value of serum EA-IgA and VCA-IgA in patients with NPC is less clear. We hypothesize that serum EA-IgA and VCA-IgA levels have prognostic impact for survival outcomes in NPC patients with undetectable pretreatment EBV (pEBV) DNA. In this series, 334 patients with non-metastatic NPC and undetectable pEBV DNA were included. Serum EA-IgA and VCA-IgA were determined by ELISA. After analysis, serum EA-IgA and VCA-IgA loads correlated positively with T, N, and overall stage (all P 1:120 had significantly inferior 5-year progression-free survival (80.4% vs 89.6%, P = 0.025), distant metastasis-free survival (88.4% vs 94.8%, P = 0.050), and locoregional relapse-free survival (88.4% vs 95.6%, P = 0.023; log-rank test). Multivariable analyses revealed that N stage was the only independent prognostic factor (all P < 0.05), but the VCA-IgA became insignificant. Further analyses revealed that serum VCA-IgA was not an independent prognostic factor in early N (N0-1) or advanced N (N2-3) stage NPC. In summary, although both EA-IgA and VCA-IgA correlate strongly with TNM stage, our analyses do not suggest that these antibodies are prognostic biomarkers in patients with NPC and undetectable pEBV DNA. © 2017 The Authors.

    Myostatin negatively regulates muscle growth, and its inhibition by suitable proteins can increase muscle bulk and exercise performance. However, the reference values of serum myostatin in athletes performing strength training are still lacking. A cross-sectional study recruiting28 male collegiate athletes performing strength training and 29 age-matched normal controls was conducted. The serum concentration of myostatin and insulin-like growth factor 1 (IGF-1), grip strength, and body composition were the main outcome measures. We used regression models to analyze the correlation between serum markers and the physiological parameters. The athlete group had greater height, weight, body mass index (BMI), fat mass percentage, fat-free mass, muscle mass, waist girth, grip strength, and estimated daily energy expenditure. The IGF-1 concentration was higher in the athlete group (324 ± 80 vs. 263 ± 134 ng/ml), but the myostatin levels did not differ (12.1 ± 3.7 vs. 12.4 ± 3.5 ng/ml). The reference value for IGF-1 among the healthy young males was 293 ± 114 ng/ml, correlated with age and height; the value for myostatin was 12.3 ± 3.6 ng/ml, correlated negatively with BMI, fat mass percentage, and waist girth after adjustment for age. Myostatin level is negatively related to fat percentage, and serum IGF-1 is positively related to height. The reference values could provide a basis for future doping-related study.

    Variation in clinical enzyme analysis, particularly across different measuring systems and laboratories, represents a critical but long-lasting problem in diagnosis. Calibrators with traceability and commutability are imminently needed to harmonize analysis in laboratory medicine. Fresh frozen human serum pools were assigned values for alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyltransferase (GGT), creatine kinase (CK) and lactate dehydrogenase (LDH) by six laboratories with established International Federation of Clinical Chemistry and Laboratory Medicine reference measurement procedures. These serum pools were then used across 76 laboratories as a calibrator in the analysis of five enzymes. Bias and imprecision in the measurement of the five enzymes tested were significantly reduced by using the value-assigned serum in analytical systems with open and single-point calibration. The median (interquartile range) of the relative biases of ALT, AST, GGT, CK and LDH were 2.0% (0.6-3.4%), 0.8% (-0.8-2.3%), 1.0% (-0.5-2.0%), 0.2% (-0.3-1.0%) and 0.2% (-0.9-1.1%), respectively. Before calibration, the interlaboratory coefficients of variation (CVs) in the analysis of patient serum samples were 8.0-8.2%, 7.3-8.5%, 8.1-8.7%, 5.1-5.9% and 5.8-6.4% for ALT, AST, GGT, CK and LDH, respectively; after calibration, the CVs decreased to 2.7-3.3%, 3.0-3.6%, 1.6-2.1%, 1.8-1.9% and 3.3-3.5%, respectively. The results suggest that the use of fresh frozen serum pools significantly improved the comparability of test results in analytical systems with open and single-point calibration.

    Objective: To study the clinical value of serum tumor marker determination and whole body bone scan for diagnosis of bone metastases from breast cancer. Methods: Serum tumor markers (CA15-3, CEA, TSGF)were detected with GLIA and whole body bone scan were investigated by SPECT in 124 breast cancer patients. Results: In 124 patients, 38 patients were diagnosed as positive for bone metastases with whole body bone scan. The positive predicting values of CA15-3, CEA, TSGF were 76.78%, 80% and 82.14%, and the negative predicting values of CA15-3, GEA, TSGF were 82.41%, 86.74% and 84.29% respectively. The levels of CA15-3, CEA, TSGF in patients with bone metastases were significantly higher than those in patients without metastasis and the controls (P<0.01). Conclusion: Determination of levels of serum tumor markers CA15-3, CEA, TSGF is helpful for diagnosis of bone metastases from breast cancer. Combined detection of GA15-3, CEA, TSGF could increase the sensitivity and accuracy of diagnosing bone metastases. (authors)

    Objective: To observe the level of serum gastrin and gastric emptying time for the liquid and solid foods in children with simple anorexia, so that it will benefit etiological diagnosis and pertinence therapy of the disease. Methods: 34 children with anorexia were recruited. 22 patients had simple anorexia (11 boys, 11 girls, median age 4.9 years). The other 12 patients had gastritis and/or gastric ulcer at the same time (3 boys, 9 girls, median age 7.3 years). 10 normal children (4 boys, 6 girls, median age 5.6 years) were compared with the patients. Serum gastrin was determined by radioimmunoassay. Gastric emptying times of the liquid and solid foods that were labelled with 113m In-DTPA were measured by nuclear multifunction instrument and nuclear imaging equipment. The gastric emptying curve for the liquid food was drawn for 15 minutes after drinking the tracer. Then, abdominal scintigraphy was performed at 1.5 hours after eating solid food containing the trace. Results: (1) Gastrin level: The level of serum gastrin was 133.7 ± 27 pg/ml in the control group, 209.7 ± 81 pg/ml in the simple anorexia group and 187.4 ± 44 pg/ml in the gastritis and/or gastric ulcer group. There was significant difference between simple anorexia group and control group (P 0.05). (2) Gastric emptying time: 8 of 14 patients with simple anorexia had prolonged gastric emptying of liquid food (57%), 6 patients (43%) had duodenogastric reflux. 5 of 12 patients (42%) with simple anorexia had delayed gastric emptying of solid food. Conclusion: Results show that simple anorexia in children may be the prophase symptom of functional indigestion. Therefore, to determine the level of serum gastrin and time of gastric emptying in children with simple anorexia may benefit etiological diagnosis and pertinence therapy. This may help to prevent chronic gastritis or gastric ulcer

    2008-01-01

    Objective: To study the clinical diagnostic value of combined determination of serum contents of CA19-9 and TGF-β in patients with pancreatic cancer. Methods: Serum CA19-9 (with RIA) and TGF-β (with ELISA) contents were deter- mined in 30 patients with pancreatic cancer and 35 controls. Results: The serum CA19-9 and TGF-β contents in patients with pancreatic cancer were significantly higher than those in controls (P<0.01). The diagnostic sensitivity of CA19-9 for pancreatic cancer was 70.8%, lower than that of TGF-β (80.2%, P<0.05). The diagnostic specificity of CA19-9 and TGF-β was 90.2% and 93.4% respectively. Conclusion: Both determinations of serum CA19-9 and TGF-β contents would yield high specificity for diagnosis of pancreatic cancer. Sensitity of TGF-β determination was higher than that of CA19-9 determination. Combined determination of CA19-9 and TGF-β would improve the diagnostic accuracy in patients with pancreatic cancer.

    Objective: To investigate the possible diagnostic value of combined determination of serum and chest fluid contents of ADA, IL-2, IL-6, IL-10 in patients with tuberculous and malignant pleural effusion. Methods: Serum and chest fluid ADA (with biochemical method), IL-2, IL-6, IL-10 (with ELISA) contents were measured in 56 patients with tuberculosis pleural effusion, 53 patients with malignant effusion and 30 controls (in serum only). The receiving operative characteristic (ROC) curve for each parameter was analyzed for study of respective area under curse (Auc). Results: The serum IL-6 levels in both groups of patients were significantly higher than those in the controls (P<0.05). The chest fluid contents of ADA, IL-2, IL-6 and IL-10 in patients with tuberculous effusion were all significantly higher than those in patients with malignancies (P<0.05). The Auc in the ROC was largest in the case of ADA, followed by IL-10, IL-6 with IL-2 the least. Conclusion: Determination of chest fluid ADA, IL-2, IL-6, IL-10 contents was helpful in the differentiation of tuberculous from malignant pleural effusion. Combined determination of chest fluid ADA and IL-10 provided the highest accuracy rate for differentional diagnosis. (authors)

    IgD multiple myeloma (MM) is a rare subtype of myeloma, it affects less than 2% of patients with MM. To evaluate the clinical and prognostic attributes of serum free light chains (sFLCs) analysis, we examined 17 cases of IgD MM. From 1998 to 2012, we obtained 1250 monoclonal gammapathies including 590 multiple myeloma and 17 patients had IgD MM. With preponderance of men patients with a mean age at diagnosis of: 59±12years. Patients with IgD MM have a short survival (Median survival=9months). The presenting features included: bone pain (75%), lymphadenopathy (16%), hepatomegaly (25%), splenomegaly (8%), associated AL amyloidosis (6%), renal impairment function (82%), infections (47%), hypercalcemia (37%) and anemia (93%). Serum electrophoresis showed a subtle M-spike (Mean=13.22±10g/L) in all patients associated to a hypogammaglobulinemia. There was an over-representation of Lambda light chain (65%); high serum β2-microglobulin in 91% and Bence Jones proteinuria was identified in 71%. The median rate of sFLCs κ was 19.05mg/L and 296.75mg/L for sFLCs λ. sFLCR was abnormal in 93% of patients and it showed concordance between baseline sFLCR and the survival (P=0.034). The contribution of FLC assay is crucial for the prognosis of patients with IgD MM. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    At present, the research on serum tumor markers in the early diagnosis of malignant tumors has aroused widespread concern. The aim of this study was to investigate the diagnostic values of serum tumor markers cytokeratin 19 fragment (Cyfra21-1), squamous cell carcinoma antigen (SCCAg), ferritin, carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9), and α-fetoprotein (AFP) for patients with oral/oropharyngeal squamous carcinoma (OSCC/OPSCC). One hundred and sixty-nine cases of patients with OSCC/OPSCC as the experimental group, 86 cases of oral benign tumor patients as the control group, and 30 cases of healthy people as the normal control group were studied. The levels of serum Cyfra21-1, SCCAg, ferritin, CEA, CA19-9, and AFP were measured using electrochemiluminescence immunoassay. The levels of serum Cyfra21-1, SCCAg, ferritin, and CEA in patients with OSCC/OPSCC were significantly higher than those of benign tumor and healthy control group (Ptumor, and healthy group (P>0.05). The level of serum Cyfra21-1 in patients with early OSCC/OPSCC (stage I + II) was significantly higher than that of benign tumor and healthy control group (PCEA, CA19-9, and AFP showed no significant difference between patients with early OSCC/OPSCC, benign tumor, and healthy control group (P>0.05). The levels of serum Cyfra21-1, SCCAg, ferritin, and CEA in the middle-late stage of patients with OSCC/OPSCC (stage III + IV) were significantly higher than those of patients with the early OSCC/OPSCC, benign tumor, and healthy control group (PCEA were 2.17, 0.72, 109.95, and 1.99 ng/mL, respectively. The sensitivities were 60.36%, 73.37%, 81.66%, and 66.27%, respectively. The specificities were 81.03%, 68.10%, 40.52%, and 61.21%, respectively. Cyfra21-1, SCCAg, ferritin, and CEA had diagnostic values for patients with OSCC/OPSCC. Meanwhile, Cyfra21-1 had better early diagnostic value for patients with OSCC/OPSCC.

    Objective: To assess the diagnostic value of combined determination of serum CA199, CA125 and CEA for cancer of pancreas. Methods: Serum CA199, CA125 and CEA levels were detected with CLIA in 32 patients with cancer of pancreas and 36 controls. Results: Positive detection rate of CA199 in patients with cancer of pancreas was 90.6% (29/32). Positive rate for CA125 and CEA was 65.6% (21/32) and 46.9% (15/32) respectively. With combined determination of these 3 tumor markers, the positive rate was 96.9% (31/32). The mean content of serum CA199 after successful operation (32.5±8.4U/ml) was significantly lower than that before operation (840.2 ± 102.5U/ml) (P<0.01). Conclusion: Combined determination of CA199, CA125 and CEA would improve the detection rate of cancer of pancreas and post-operative changes of CA199 could be of prognostic value. (authors)

    Objective: To explore the value of combined examination of serum tumormarkers carbohydrate antigen 15-3 (CA15-3), carcinoembryonic antigen (CEA) and whole body bone scan in the diagnosis of bone metastasis in breast cancer. Methods: Whole body bone scan and serum CA15-3 and CEA levels with a electrochemical luminescence assay were performed in 97 patients with breast cancer (46 cases with bone metastasis and 51 cases without bone metastasis) and 45 patients with benign breast diseases. As for the negative cases who had significant pains in bones, CT or MRI was performed to make sure. Results: The serum level of CA15-3 and CEA were significantly higher in patients with bone metastasis than those in patients without bone metastasis and the benign lesions. The positive predicting values were 76.09% and 80.43%. Most patients with bone metastasis had positive results in bone scan (95.65%), only 2 cases had negative results (4.35%), which is positive by CT or MRI Seven. Seven patients without bone metastasis and Three patients with the benign lesions had positive results in bone scan, that may be caused by previous operation or injury. The combined determination of CA15-3, CEA and whole body bone scan had a better performance in sensitivity, specificity and accuracy than each single way. Conclusion: The combined determination of CA 15-3, CEA and whole body bone scan were valuable in the diagnosis of bone metastasis in breast cancer. (authors)

    Objectives: To determine the level of serum procalcitonin, blood leukocyte count (TLC) and C-reactive protein (CRP) in children with bacterial and non bacterial meningitis and document their efficacy in differential diagnosis. Also described are procalcitonin levels variation during treatment. Methods: From March 2005 to February 2008, we evaluated 38 clinically suspected meningitis patients in the paediatric departments, Al-Jedaany Hospital, Jeddah, KSA, for Serum procalcitonin, CRP, TLC and Lumbar punctures and CSF analysis. Patients were classified into bacterial meningitis group I (18) and non bacterial meningitis group II (20). Results: Serum PCT levels were significantly higher in bacterial meningitis (BM) 9 mean 4.8 +- 3.85 ng/ml (2.9-11.6)) compared with non bacterial meningitis (NBM) (mean 0.38 +- 0.25 ng/ml(0.31-0.61)) P< 0.001). Mean of all CSF parameters, TLC (15,000 +- 2,900 cell/ml(BM) and 9,500 +-1,105 cell/ml(NBM))and CRP (20 +- 6.8 mg/l (BM) and 12.5 +-12.0 mg/l(NBM))showed a zone of overlapping between the two groups. There is a positive correlation between serum PCT, TLC and CRP in bacterial and non bacterial meningitis cases but this relation becomes highly significant with bacterial meningitis positive group. Day 3 and day 6 treatment serum PCT was less than on admission levels (P<0.001). Conclusion: PCT can be used in the early diagnosis of bacterial meningitis and may be a useful adjunct in differentiating bacterial and non bacterial meningitis than CRP or TLC and diminishing the value of lumbar puncture performed 48-72 hours after admission to assess treatment efficacy.

    An increase of the serum PSA-level is a sensitive in vitro marker for recurrent prostate cancer. However, it remains difficult to differentiate between local, regional or distant recurrent disease. The aim of this study was to assess the relationship between the detection rate of [ 11 C]Choline-PET/CT and the serum PSA-level in patients with a biochemical recurrence of prostate cancer with the view towards localisation of recurrent disease. Sixty-three patients (mean age, 68.8 ± 6.9; range, 45-83 years) with biochemical recurrence after primary therapy for prostate cancer were included in the analysis. Mean PSA-levels were 5.9 ± 9.7 ng/ml (range, 0.2-39 ng/ml; median, 2.15). Of the 63 patients, 17 were under anti-androgen therapy at the time of [ 11 C]Choline PET/CT. Patients underwent a [ 11 C]Choline-PET/CT study after injection of 656 ± 119 MBq [ 11 C]Choline on a Sensation 16 Biograph PET/CT scanner. Of the 63 patients, 35 (56%) showed a pathological [ 11 C]Choline uptake. The detection rate of [ 11 C]Choline-PET/CT showed a relationship with the serum PSA-level: The detection rate was 36% for a PSA-value 11 C]Choline-PET/CT (p = 0.374). As an important result our study shows that even for PSA-values 11 C]Choline-PET/CT is 36%. Furthermore, the detection rate of [ 11 C]Choline-PET/CT shows a positive relationship with serum PSA-levels in patients with biochemical recurrence of prostate cancer after primary therapy. Therefore, in these patients, [ 11 C]Choline PET/CT allows not only to diagnose but also to localise recurrent disease with implications on disease management (localised vs systemic therapy).

    Objective: To explore the value of combined examination of serum tumor markers CYFRA21-1 and bone scan in the diagnosis of bone metastasis in lung cancer. Methods: Bone scan and serum CYFRA21-1 levels (with CLIA) determination were performed in 138 patients with lung cancer and 56 patients with benign lung diseases. Results: The serum level of CYFRA21-1 were significantly higher in patients with bone metastasis than those in patients without bone metastasis. The levels were also higher in patients without bone metastasis than those in controls. Most patients with bone metastasis had positive results in bone scan (97.4%), only 2 of the 78 had negative bone scan but positive with CT or MRI. A few patients without bone metastasis and controls had positive bone scan results, caused by previous operation or injury. Conclusion: The combined detection of CYFRA21-1 and bone scan were valuable in the diagnosis of bone metastasis of lung cancer. (authors)

    Full Text Available BACKGROUND: A variety of indicators of potentially successful ovarian stimulation cycles are available, including biomarkers such as anti-Mullerian hormone. The aim of our study was to confirm the usefulness of serum anti-Mullerian hormone assay in predicting ovarian response and reproductive outcome in women eligible for ART cycles. MATERIALS: Forty-six women undergoing ART cycles at the Centre for Reproductive Medicine in Parma were recruited from March-to-June 2010. INCLUSION CRITERIA: age<42 years; body-mass-index = 20-25; regular menstrual cycles; basal serum FSH concentration <12 IU/L and basal serum estradiol concentration <70 pg/mL. The couples included in our study reported a variety of primary infertility causes. All women underwent FSH stimulation and pituitary suppression (GnRH-agonist/GnRH-antagonist protocols. Women were considered poor-responders if they had ≤ 3 oocytes; normal-responders 4-9 oocytes and high-responders ≥ 10 oocytes. Serum samples for the AMH assays were obtained on the first and last days of stimulation. A P value ≤ 0.05 was considered statistically significant. RESULT: FSH levels increased significantly when AMH levels decreased. The total dose of r-FSH administered to induce ovulation was not correlated to AMH. The number of follicles on the hCG, serum estradiol levels on the hCG-day, and the number of retrieved oocytes were significantly correlated to AMH. The number of fertilized oocytes was significantly correlated to the AMH levels. No significant correlation was found between obtained embryos or transferred embryos and AMH. Basal serum AMH levels were significantly higher than those measured on the hCG-day, which appeared significantly reduced. There was a significant correlation between AMH in normal responders and AMH in both high and poor responders. CONCLUSIONS: Our data confirm the clinical usefulness of AMH in ART-cycles to customize treatment protocols and suggest the necessity of verifying an

    The levels of liver function tests (LFTs) are often used to assess liver injury and non-liver disease-related mortality. In our study, the relationship between pretreatment serum LFTs and overall survival (OS) was evaluated in esophageal squamous cell carcinoma (ESCC) patients. Our purpose was to investigate the prognostic value of the preoperative alanine aminotransferase/aspartate aminotransferase (ALT/AST) ratio and gamma glutamyltransferase (GGT) in ESCC patients. A retrospective study was performed in 447 patients with ESCC, and follow-up period was at least 60 months until death. The prognostic significance of serum LFTs were determined by univariate and multivariate Cox hazard models. LFTs including ALT, AST, LSR, GGT, TBA and LDH were analyzed. Serum LSR (HR: 0.592, 95% CI = 0.457-0.768, p < 0.001 and GGT (HR: 1.507, 95% CI = 1.163-1.953, p = 0.002) levels were indicated as significant predictors of OS. The 5-year OS among patients with higher LSR levels was longer compared with those patients with decreased LSR levels, not only in the whole cohort but also in the subgroups stratified by pathological stage (T1-T2 subgroup, T3-T4 subgroup, N0 subgroup and M0 subgroup). We also found that patients with a higher GGT might predict worse OS than patients with a normal GGT, not only in the whole cohort but also in the subgroups stratified by pathological stage (T3-T4 subgroup and N1-N2 subgroup). Both increased levels of LSR and decreased levels of GGT might predict shorter overall survival in ESCC patients. Our findings suggest that serum LSR and GGT levels could be used as a key predictor of survival in patients with ESCC.

    Full Text Available IgG4-related disease is a new disease classification established in Japan in the 21st century. Patients with IgG4-related disease display hyper-IgG4-gammaglobulinemia, massive infiltration of IgG4+ plasma cells into tissue, and good response to glucocorticoids. Since IgG4 overexpression is also observed in other disorders, it is necessary to diagnose IgG4-related disease carefully and correctly. We therefore sought to determine cutoff values for serum IgG4 and IgG4/IgG and for IgG4+/IgG+ plasma cells in tissue diagnostic of IgG4-related disease. Patients and Methods. We retrospectively analyzed serum IgG4 concentrations and IgG4/IgG ratio and IgG4+/IgG+ plasma cell ratio in tissues of 132 patients with IgG4-related disease and 48 patients with other disorders. Result. Serum IgG4 >135  mg/dl demonstrated a sensitivity of 97.0% and a specificity of 79.6% in diagnosing IgG4-related disease, and serum IgG4/IgG ratios >8% had a sensitivity and specificity of 95.5% and 87.5%, respectively. IgG4+cell/IgG+ cell ratio in tissues >40% had a sensitivity and specificity of 94.4% and 85.7%, respectively. However, the number of IgG4+ cells was reduced in severely fibrotic parts of tissues. Conclusion. Although a recent unanimous consensus of all relevant researchers in Japan recently established the diagnostic criteria for IgG4-related disease, findings such as ours indicate that further discussion is needed.

The impact of UA on CV events and mortality in CKD is unclear. Objective. To assess the relationship between UA and prognosis in hemodialysis (HD patients before and after renal transplantation (TX. Methods. 1020 HD patients assessed for CV risk and followed from the time of inception until CV event, death, or TX (HD or date of TX, CV event, death, or return to dialysis (TX. Results. 821 patients remained on HD while 199 underwent TX. High UA (≥428 mmol/L was not associated with either composite CV events or mortality in HD patients. In TX patients high UA predicted an increased risk of events (P=0.03, HR 1.6, and 95% CI 1.03–2.54 but not with death. In the Cox proportional model UA was no longer significantly associated with CV events. Instead, a reduced GFR (<50 mL/min emerged as the independent risk factor for events (P=0.02, HR 1.79, and % CI 1.07–3.21. Conclusion. In recipients of TX an increased posttransplant UA is related to higher probability of major CV events but this association probably caused concurrent reduction in GFR.

    Immunoglobulin free light chains (FLCs) are the precursors of amyloid fibrils in primary amyloidosis (AL). We studied the relationship between FLC levels and clinical features in 730 patients with newly diagnosed AL. The plasma cell clone was λ in 72% patients, and κ in 28% patients. κ-AL had more GI tract and liver involvement, where as renal involvement was more with λ-AL. While the overall survival (OS) was similar for κ and λ-AL, the median OS for those without an identifiable serum heavy chain was significantly shorter (12.6 vs 29.9 months; P = .02). The OS was shorter among those with a higher dFLC (involved FLC-uninvolved FLC; κ > 29.4 mg/dL or λ > 18.2 mg/dL using median for cutoff); 10.9 vs 37.1 months; P analysis, dFLC was independent of other prognostic factors. The type of light chain impacts the spectrum of organ involvement and the FLC burden correlates with survival in AL.

    Polycystic ovarian morphology (PCOM) at ultrasound is currently used in the diagnosis of polycystic ovary syndrome (PCOS). We hypothesized that the previously proposed threshold value of 12 as an excessive number of follicles per ovary (FN) is no longer appropriate because of current technological developments. In this study, we have revisited the thresholds for FN and for the serum Anti-Müllerian hormone (AMH) level (a possible surrogate for FN) for the definition of PCOM. Clinical, hormonal and ultrasound data were consecutively recorded in 240 patients referred to our department between 2008 and 2010 for exploration of hyperandrogenism (HA), menstrual disorders and/or infertility. According to only their symptoms, patients were grouped as: non-PCOS without HA and with ovulatory cycles (group 1, n = 105), presumption of PCOS with only HA or only oligo-anovulation (group 2, n = 73) and PCOS with HA and oligo-anovulation (group 3, n = 62). By cluster analysis using androgens, LH, FSH, AMH, FN and ovarian volume, group 1 appeared to be constituted of two homogeneous clusters, most likely a non-PCOM non-PCOS subgroup (n = 66) and a PCOM, non-PCOS (i.e. asymptomatic) subgroup (n = 39). Receiver operating characteristic curve analysis was applied to distinguish the non-PCOM non-PCO members of group 1 and to group 3. For FN and serum AMH respectively, the areas under the curve were 0.949 and 0.973 and the best compromise between sensitivity (81 and 92%) and specificity (92 and 97%) was obtained with a threshold values of 19 follicles and 35 pmol/l (5 ng/ml). For the definition of PCOM, the former threshold of >12 for FN is no longer valid. A serum AMH >35 pmol/l (or >5 ng/ml) appears to be more sensitive and specific than a FN >19 and should be therefore included in the current diagnostic classifications for PCOS.

    To evaluate preoperative serum levels of Ca125 and Tag72-4 tumour markers and investigate if abnormal levels correlate to mortality and disease-free survival. Retrospective observational study of a cohort of 282 women (mean age 62.3, SD 10.5 years) with primary endometrial cancer included all consecutive cases treated in a tertiary Gynaecological oncology Center. Excluded cases with other cancer or previous cancer treatment, major abdominal pathology or inflammation, endometriosis. Preoperative serum Tag72 and Ca125 levels were determined and evaluated in relation to disease-free survival (DFS) and disease-specific overall survival (DOS). Raised Ca125 correlates to worse overall disease-specific survival (66.1 vs 87.8 months, p = 0.021) and Tag72 correlates to shorter disease-free survival (69.2 vs 67.3 months, p = 0.021) and higher recurrence rate (13.5 vs 6 %, p = 0.021). When both Ca125 and Tag72 are abnormal DFS and DOS are worse. 93.3 % (72.3 months) vs 82.4 %, (61.3 months) p = 0.018 and 96.3 % (74.8 months) vs 88.2 %, (65.9 months) p = 0.021, respectively. This study enhances the value of preoperative tumour markers and their prognostic value. Ca125 and Tag72 appear to be good predictors of poor prognosis in patients with endometrial cancer.

    Background The predictive and prognostic value of carcinoembryonic antigen (CEA), cytokeratin-19 fragments (Cyfra21-1), squamous cell carcinoma antigen (SCCA) and neuron-specific enolase (NSE) has been investigated in non-small-cell lung cancer (NSCLC) patients. However, few studies have directly focused on the association between these markers and epidermal growth factor receptor (EGFR) mutation status or mutation subtypes. Patients and methods We retrospectively analyzed 1016 patients with stage I-IIIA NSCLC who underwent complete resection between 2008 and 2012. Correlations between serum tumor marker levels and EGFR mutations and survival parameters were analyzed and prognostic factors were identified. Results Cyfra21-1 levels (P = 0.032 for disease-free survival [DFS]; P CEA levels (P CEA (P = 0.005) and clinical stage were predictive factors of DFS, while elevated CEA (P = 0.005) and Cyfra21-1 (P = 0.027) were independent prognostic factors. Conclusion Cyfra21-1 and CEA exhibit different predictive and prognostic values between EGFR-mutated and wild-type adenocarcinomas, as well as between EGFR mutation subtypes. The prognostic impact of preoperative serum tumor markers should be evaluated together with EGFR mutation status. PMID:27072585

    This meta-analysis aimed to perform a systematic review on comparing the diagnostic value of serum cystatin C and creatinine for glomerular filtration rate in renal transplant patients. The data was extracted into 2×2 table after the articles were assessed by the tool of QUADAS and heterogeneity analysis. The SROC curve and meta-analysis were performed by MetaDisc1.4. Meta-analysis showed that the serum cystatin C had no heterogeneity (P=0.418, I2=2.2%, DOR=25.03), while creatinine heterogeneity was high (P=0.109, I2=37.5%, DOR=9.11). The values of SEN, SPE and SAUC were calculated as 0.86, 0.70 and 0.9015 for cystatin C, and 0.78, 0.73 and 0.8285 for creatinine individually. This study utilized GFR detection and subgroups analysis by cutoff. The PLR was 6.13 and the NLR was 0.12 for cystatin C, compared to SCr (3.72, 0.32). There was homogeneity among these studies using PENIA testing for cystatin C (χ2=2.61, P=0.4560, I2=0.0%. There were significant correlations among cystatin C , creatinine and glomerular filtration rate (GFR). Cystatin C had more sensitivity but less specificity than creatinine for evaluation of GFR. Cystatin C had strong ability in diagnosing renal function after renal transplant and ruling out diagnostic efficacy.

    To evaluate the application value of serum CA19-9, CEA, CA125 and CA242 in diagnosis and prognosis of pancreatic cancer cases treated with concurrent chemotherapy. 52 patients with pancreatic cancer, 40 with benign pancreatic diseases and 40 healthy people were selected. The electrochemiluminescence immunoassay method was used for detecting levels of CA19-9, CEA and CA125, and a CanAg CA242 enzyme linked immunoassay kit for assessing the level of CA242. The Kaplan-Meier method was used for analyzing the prognostic factors of patients with pancreatic cancer. The Cox proportional hazard model was applied for analyzing the hazard ratio (HR) and 95% confidential interval (CI) for survival time of patients with pancreatic cancer. The levels of serum CA19-9, CEA, CA125 and CA242 in patients with pancreatic cancer were significantly higher than those in patients with benign pancreatic diseases and healthy people (PCEA. The specificity of CA242 is the highest, followed by CA125, CEA and CA19-9. The sensitivity and specificity of joint detection of serum CA19-9, CEA, CA125and CA242 were 90.4% and 93.8%, obviously higher than single detection of those markers in diagnosis of pancreatic cancer. The median survival time of 52 patients with pancreatic cancer was 10 months (95% CI7.389~12.611).. Patients with the increasing level of serum CA19-9, CEA, CA125, CA242 had shorter survival times (P=0.047. 0.043, 0.0041, 0.029). COX regression analysis showed that CA19-9 was an independent prognostic factor for patients with pancreatic cancer (P=0.001, 95%CI 2.591~38.243). The detection of serum tumor markers (CA19.9, CEA, CA125 and CA242) is conducive to the early diagnosis of pancreatic cancer and joint detection of tumor markers helps improve the diagnostic efficiency. Moreover, CA19-9 is an independent prognostic factor for patients with pancreatic cancer.

    Full Text Available Introduction: Inhibin-B is glycoproteins of the transforming growth factor-β superfamily, is produced almost exclusively by the Sertoli cells and has been proposed as direct markers of their function and indirect markers of spermatogenesis. Our objective was to evaluate the predictive value of serum Inhibin-B levels as an indicator of the presence of testicular spermatozoa in non-obstructive azoospermia (NOA, compared with other markers such as FSH and testicular volume. Material and methods: A total of 228 patients with idiopathic non-obstructive azoospermia (NOA were recruited in this prospective study. Inhibin-B in serum has been evaluated before sperm retrieval by Enzyme-Linked Immuno-Sorbent Assay (Elisa, in addition to FSH and testosterone. Testicular volume was measured by sonography. Testicular Fine Needle Aspiration (FNA and Testicular Sperm Extraction (TESE were performed for sperm retrieval. The patients were classified according to the presence or absence of Testicular spermatozoa into two groups (I and II respectively. Results: Spermatozoa were retrieved in 87 patients (38.16%, classified as group I and were absent in 141 patients (61.84% classified as group II. Mean serum Inhibin-B ± SD was significantly higher in group I than in group II, 71.77 versus 27.49 respectively (P < 0.001. The odds ratio of Inhibin-B for success of sperm retrieval was 1.0409 (95% CI: 1.0286–1.0533. Serum Inhibin-B demonstrated that the best inhibin-B value threshold for discriminating between successful and failed sperm retrieval was 35 pg/ml, with a sensitivity of 75.86 (95% Confidence interval [CI]: 65.5–84.4 and specificity of 80.85 (CI: 73.4–87.0 for the prediction of the presence of testicular spermatozoa as determined by the receiver operating characteristic (ROC curve analysis and area under curve (AUC. Conclusions: Inhibin-B might be a predictive marker of persistent spermatogenesis in the men with non-obstructive azoospermia.

    This study was to investigate the diagnostic value of serum procalcitonin(PCT) in identifying the etiology of non-responding community-acquired pneumonia (CAP) after initial antibiotic therapy. A retrospective analysis was performed for 232 hospitalized CAP patients admitted to the People's Hospital of Zhengzhou University during June 2013 and January 2014. Early treatment failure was defined as the presence of persistent fever (>38 °C) and/or clinical symptoms (malaise, cough, expectoration, dyspnea) or deterioration after at least 72 h of initial antimicrobial treatment, or development of respiratory failure requiring mechanical ventilation, or septic shock. Bronchoscopy or transthoracic lung biopsy was performed in case of early treatment failure when indicated. Serum level of PCT was detected by double antibody sandwich method. The differences between 2 or more groups were compared using 2-independent student t test, one-way ANOVA; Mann-Whitney U test, Kruskal-Wallis rank sum test, or χ(2) test. Risk factors and odds ratios for nonresponsiveness were analyzed by setting up a Logistic regression model. The diagnostic values of PCT were determined by receiver operating characteristic curves (ROC curves). Of the 232 CAP patients enrolled, 124 were male and 108 were female, with an average age of (46 ± 20) years. Thirty-six patients failed to respond to the initial antibiotic therapy. As shown by Logistic regression analysis, the risk factors for treatment failure included hypoalbuminemia, type 2 diabetes, previous history of splenectomy , PSI 4-5 grade, and lung infiltration ≥ 3 lobes. The most common causes of non-responsiveness were antimicrobial insufficiency (n = 23), and misdiagnosis of noninfectious mimics of pneumonia (n = 11), with 2 cases of unidentified etiology. The serum PCT level in admission was 0.19 (0.07-0.66) µg/L in the antimicrobial insufficiency subgroup, which was significantly higher than that in the misdiagnosis subgroup [0

    The purpose of this study is to investigate the diagnostic value of transvaginal sonograph (TVS), color Doppler, and serum tumor marker CA125, CEA, and AFP in ovarian cancer. From June, 2011 to May, 2013, 102 cases with adnexal mass were recruited in this study (32 cases of malignant ovarian cancer and 70 cases of benign ovarian tumor according to pathological diagnosis). TVS, color Doppler, and serum tumor markers were used for tumor diagnosis. The sensitivity, specifity, positive prediction, negative prediction, and Youden's index were analyzed. Of the 102 patients, 32 were diagnosed with malignant ovarian cancer and 70 were diagnosed with benign ovarian tumor according to pathological diagnosis. Based on TVS results, 37 cases were malignant while 65 cases were benign. Based on color Doppler results, 34 cases were malignant while 68 cases were benign. Based on TVS and color Doppler results, 35 cases were malignant while 65 were benign. Based on CA125 test results, 34 cases were malignant while 68 cases were benign. Based on CEA test results, 8 cases were malignant and 94 cases were benign. Bases on AFP test results, 9 cases were malignant while 93 cases were benign. Based on the results of combination tumor marker test, 38 cases were malignant while 64 cases were benign. The combination of TVS, color Doppler, and tumor marker test showed optimal diagnostic value with a sensitivity of 90.63 %, specificity of 97.14 %, positive prediction of 93.94 %, negative prediction of 98.55 %, and Youden's index of 94.02 %. The combination of TVS, color Doppler, and tumor marker test is of great diagnostic value, which should be widely used in clinical practice.

    Purpose: Myocardial T2* cardiovascular magnetic resonance provides a rapid and reproducible assessment of cardiac iron load in thalassemia patients. Although cardiac involvement is mainly characterized by left ventricular dysfunction caused by iron overload, little is known about right ventricular function. The aim of this study was to assess the relationship between T2* value in myocardium and left–right ventricular volumetric and functional parameters and to evaluate the existing associations between left–right ventricles volumetric and functional parameter, myocardial T2* values and blood ferritin levels. Materials and methods: A retrospective analysis of 208 patients with β-thalassemia major and thalassemia intermedia was performed (109 males and 99 females; mean age 37.7 ± 13 years; 143 thalassemia major, 65 thalassemia intermedia). Myocardial iron load was assessed by T2* measurements, and volumetric functions were analyzed using the steady state free precession sequence. Results: A significant correlation was observed between EFLV and T2* (p = 0.0001), EFRV and T2* (p = 0.0279). An inverse correlation was present between DVLV and T2* (p = 0.0468), SVLV and T2* (p = 0.0003), SVRV and T2* (p = 0.0001). There was no significant correlation between cardiac T2* and LV–RV mass indices. A significant correlation was observed between T2* and serum ferritin levels (p < 0.001) and between EFLV and serum ferritin (p < 0.05). Conclusion: Myocardial iron load assessed by T2* cardiac magnetic resonance is associated with deterioration in left–right ventricular function; this is more evident when T2* values fall below 14 ms. CMR appears to be a promising approach for cardiac risk evaluation in TM patients.

    Gastric cancer (GC) is the second cause of cancer related death in the world. It may develop by progression from its precancerous condition, called gastric atrophy (GA) due to gastritis. The aim of this study was to evaluate the accuracy of serum levels of pepsinogens (Pg) and gastrin-17 (G17) as non-invasive methods to discriminate GA or GC (GA/GC) patients. Subjects referred to gastrointestinal clinics of Golestan province of Iran during 2010 and 2011 were invited to participate. Serum levels of PgI, PgII and G17 were measured using a GastroPanel kit. Based on the pathological examination of endoscopic biopsy samples, subjects were classified into four groups: normal, non-atrophic gastritis, GA, and GC. Receiver operating curve (ROC) analysis was used to determine cut-off values. Indices of validity were calculated for serum markers. Study groups were normal individuals (n=74), non-atrophic gastritis (n=90), GA (n=31) and GC patients (n=30). The best cut-off points for PgI, PgI/II ratio, G17 and HP were 80 μg/L, 10, 6 pmol/L, and 20 EIU, respectively. PgI could differentiate GA/GC with high accuracy (AUC=0.83; 95%CI: 0.76-0.89). The accuracy of a combination of PgI and PgI/II ratio for detecting GA/GC was also relatively high (AUC=0.78; 95%CI: 0.70-0.86). Our findings suggested PgI alone as well as a combination of PgI and PgI/II ratio are valid markers to differentiate GA/GC. Therefore, Pgs may be considered in conducting GC screening programs in high-risk areas.

    Full Text Available OBJECTIVES: With normal hysterosalpingography (HSG results, selecting suitable candidates for the laparoscopic treatment of probable pelvic adhesions following previous pelvic inflammatory disease, it would be wise to investigate serum antibody screening against chlamidia trachomatis. It is worth to evaluate whether it is useful to detect a negative antichlamidial antibody disease for cancelling laparoscopy for a while with abnormal HSG findings. These two subjects have been investigated in study. MATERIAL AND METHODS: For detecting diagnostic value of serum antichlamidial antibody, in our infertility clinic, postoperative blood samples of 80 patients who were hospitalized for diagnostic laparoscopy to investigate infertility ethiology between May 2004 and November 2005 have been tested with microelisa method for antichlamidial IgM and IgG antibodies. HSG films of the patients performed at least one year were evaluated. Venous blood was drawn from these patients during postoperative early period for studying serum IgM and IgG antibodies of chlamidia trachomatis and the results were compared with operative findings. RESULTS: According to the antichlamidial antibody levels 60 (75% patients have not been infected with chlamidia and 20 (25% patients have been infected previously. When the patients were divided to two groups; normal and abnormal; based on preoperative HSG films; 18 (30% of the 60 patients with abnormal HSG films and 2 (10% of the 20 patients with normal HSG films had positive antichlamidial antibody levels respectively. CONCLUSION: The relationship between chlamidia trachomatis infection and tubal infertility has been demonstrated among 85% of patients with positive antichlamidial antibody levels and 46.7% of patients with negative levels who had tubal passage defects detected during diagnostic laparoscopy.

    The experimental materials comprised 44 hybrid [female (Polish Large White x Polish Landrace) x male Duroc] growing-finishing pigs. The animals were randomly divided into two groups: 24 pigs were slaughtered immediately after transport and 20 pigs were slaughtered after a 24-hour rest period in the lairage. The meat content of pork carcasses, carcass dressing percentage, the proximate chemical composition, physicochemical and sensory properties of meat and shear force values were determined. Serum creatine kinase activity and cortisol levels were determined in blood samples collected before transport and during carcass bleeding. Pigs slaughtered immediately after transport, compared with those slaughtered after a 24-hour rest period, were characterized by a higher meat content of the carcass and a higher carcass dressing percentage. Pre-slaughter handling had no effect on pork quality. The incidence of normal-quality meat, partially PSE (pale, soft, exudative) meat and PSE meat was similar in both groups. Chemical analysis showed that the content of dry matter, total protein, fat and minerals in meat was comparable in both groups. As regards the functional properties of the pork, samples from the carcasses of pigs that had rested before slaughter had a higher contribution of the red color component. Meat from pigs slaughtered immediately after transport had more desirable sensory properties. Pre-slaughter resting had a significant effect on those analyzed physiological parameters which were found to be good indicators of pre-slaughter stress. Serum creatine kinase activity and cortisol levels were higher in blood samples collected after transport (during carcass bleeding) than in samples collected before transport, pointing to a strong stress response of animals to pre-slaughter treatment. The decrease in serum cortisol levels in blood samples collected during bleeding from the carcasses of pigs slaughtered after a 24-hour rest period, compared with samples

    To evaluate the value of three tumor markers serum Golgi phosphoprotein-3 (GOLPH3), cancer antigen 125 (CA125) and cancer antigen 19-9 (CA19.9) in the diagnosis and postoperative evaluation of ovarian cancer by detecting these three markers. A total of 187 patients were studied and included in the ovarian cancer group, benign pelvic mass group, and the normal control group. The levels of serum Golgi phosphoprotein-3 (GOLPH3), cancer antigen 125 (CA125) and cancer antigen 199 (CA19.9) were detected, respectively, and their effects on the diagnosis, evaluation, pathology typing and staging of ovarian cancer were measured. The sensitivity of the detection of ovarian cancer by GOLPH3 combined with CA125 and CA19.9 was higher than that by a single marker (pserum GOLPH3 in patients with serous and endometrioid carcinoma was significantly higher than that in patients with mucinous carcinoma, clear-cell carcinoma and germ cell tumor (pserum GOLPH3 level between patients with ovarian malignancies at stage III-IV and those at stage I-II (p>0.05). The levels of serum GOLPH3, CA125 and CA19.9 in patients with ovarian malignancies after surgery were significantly lower than those before surgery (p<0.05). The combined detection by GOLPH3, CA125, and CA19.9 may improve the diagnosis rate of ovarian epithelial cancer. GOLPH3, as a new ovarian cancer tumor marker used in clinical diagnosis, is expected to become an important indicator for the early diagnosis of ovarian cancer and the determination of clinical surgery efficacy.

    Recent issues surrounding captive amphibians are often nutritionally related problems, such as hypovitaminosis A. Although supplementation of frogs with vitamin A is a topic of investigation, the underlying issue is understanding vitamin A metabolism in amphibian species. To develop a range of "normal" vitamin A concentrations for captive amphibians, baseline vitamin A concentrations must be established in wild amphibian species. In this study, two species, Cuban tree frogs (Osteopilus septentrionalis; n = 59) and marine toads (Rhinella marina; n = 20) were collected from the wild as part of an invasive species control program at Zoo Miami, Miami, Florida. Serum, liver, and whole body samples were analyzed for vitamin A content. The Cuban tree frogs showed higher concentrations on average of vitamin A in serum (82.8 ppb), liver (248.3 IU/g), and whole body (5474.7 IU/kg) samples compared with marine toads (60.1 ppb; 105.3 IU/g; 940.7 IU/kg, respectively), but differences were not significant (P = 0.22). What can be considered "normal" values of vitamin A concentrations across different amphibian species requires further investigation. Although all amphibians collected in this study appeared healthy, a larger sample size of animals, with known health histories and diets, may provide stronger evidence of normal expectations.

    Objective: To study the clinical diagnostic value of determination of serum ischemia modified albumin (IMA), homocysteine (Hcy) and high-sensitivity C-reactive protein (hs-CRP) levels in patients with acute coronary syndrome (ACS). Methods: Serum IMA (with albumin-cobalt binding assay), Hcy (with ELISA) and hs-CRP (with RIA) levels were determined in 73 patients with ACS within 3 hours after onset of chest pain and 40 controls. Results: The sensitivity of IMA was 87.67%, the specificity was 100%. The area under curve of ROC was 0.985 (95% confidence interval 0.969 ∼ 1.001). All the figures were higher than those of Hcy and hs-CRP. Combined determination of IMA, Hcy and hs-CRP, would increass the sensitivity to 97.26%. Conclusion: IMA is one of the earliest sensitive indicators for clinical diagnosis of early myocardial ischemia in patients with ACS. Combined determination of IMA, Hcy and hs-CRP would be even more sensitive. (authors)

    The daily exposure to Ni from food, industrial processes, jewellery and coins makes the determination of Ni in human serum an important way to monitor the health status in non-occupationally exposed subjects. To this end, a method based on sector-field inductively coupled plasma mass spectrometry was developed and validated. The limits of detection (LoD) and quantification (LoQ), sensitivity, linearity range, trueness, repeatability, within-laboratory reproducibility and robustness were the considered issues of the validation process. The uncertainty associated with the measurements was also calculated, according to the Eurachem/Citac Guide. The method LoD and LoQ were 0.03 and 0.09 ng mL(-1), linearity was over two order of magnitude, trueness was -3.57%, and the repeatability and reproducibility showed relative standard deviations equal to 4.56% and 6.52%, respectively. The relative expanded uncertainty was 21.8% at the Ni levels found in the general population. The tentative reference value for serum Ni was 0.466 +/- 0.160 ng mL(-1) with a related interval between 0.226 and 1.026 ng mL(-1). Copyright 2006 John Wiley & Sons, Ltd.

    The purpose of this study was to evaluate whether the apolipoprotein B/apolipoprotein A-I (apoB/apoA-I) ratio is a promising risk predictor of metabolic syndrome (MetS) and to determine the optimal cut-off value of this ratio in detecting subjects with MetS in a Chinese population. A prospective study was conducted using a representative sample of non-institutionized people in Taiwan. A total of 3,343 participants with mean age (±SD) of 39.86 (±15.61) years old were followed up from 2002 to 2007. The primary outcome was the incidence of MetS. The MetS was defined according to a unified criterion established by several major organizations. There were 462 cases of incident MetS during a mean follow-up period of 5.26 years. A significantly stepwise increase in the incidence of MetS across quartiles of the apoB/apoA-I ratio was noted in both sexes after adjustment for potential confounders (p for trend risk of MetS in both men [adjusted hazard ratio (HR) = 6.29, 95 % confidence interval (CI) = 2.79-9.13] and women (adjusted HR = 3.82, 95 % CI = 1.06-6.63). Comparisons of receiver operating characteristics curves indicated that the predictive ability of apoB/apoA-I ratio to detect MetS was better than conventional lipid ratio measurements. Furthermore, the optimal cut-off value of apoB/apoA-I ratio for MetS diagnosis was 0.71 in men and 0.56 in women. These results suggest that an elevated apoB/apoA-I ratio might constitute a potentially crucial measure linked to the risk of developing MetS.

    suero/plasma.OBJECTIVE: To review and analyze the literature on selenium (Se levels in human serum and plasma; to describe some variations; to obtain reference values for the countries of Europe and Latin America, and to provide an information framework for future studies on the subject. METHODS: Scientific literature was reviewed to gather information on selenium serum or plasma levels in people identified as "healthy." The LILACS, SciELO, and PubMed Medline databases were consulted. The search for information could be from any date (up to January 2010 and in any language. Weighted arithmetic means and standard deviations were calculated. RESULTS: For Europe, 161 reports published between 1972 and 2009 were found, covering 49 869 healthy adults, 28 countries, and 8 regions. Serum/plasma Se levels ranged from 48.2 to 124.00 µg/L. Weighted values for Europe were 85.19 ± 14.58 (CI 95% for the weighted average, 85.124-85.256. The averages by country, region, and measurement technique were statistically different, with significant differences associated with sex and age. Twenty-three of the studies involved individuals under 19 years of age in 10 European countries. The weighted values for this population were 74.21 ± 9.50 µg/L (CI 95%, 73.95-74.46. Only 11 studies from Latin America were available. Serum/plasma Se was 91.51 ± 18.78 Ìg/L in adults; 93.25 ± 39.20 in children under 15; and 130 ± 30 in newborns less than 25 hours old. CONCLUSIONS: Se serum/plasma levels in Europe showed statistically significant differences by sex and age. Se levels were higher in Latin American adults and children than in Europeans, but the Latin American data are based on few people. The technique for measuring Se in serum/plasma appears to have a significant influence. Properly planned and designed population studies should be conducted in Latin America in order to establish regional reference values for Se in serum and plasma.

    The M-type phospholipase A2 receptor (PLA2R) is a specific target autoantigen identified in idiopathic membranous nephropathy (IMN). The autoantibody against PLA2R (anti-PLA2R) may be used to diagnose IMN. However, the appropriate diagnosis cut-off value for Chinese patients with IMN has not been established. In total, 119 patients who underwent renal biopsy (57 patients with IMN and 62 patients with non-IMN glomerulonephritis) and 22 healthy individuals were recruited for our observation study from Qianfoshan Hospital between September 2011 and March 2016. The serum concentration of anti-PLA2R was measured using a quantitative enzyme-linked immunosorbent assay (ELISA). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and receiver operating characteristic (ROC) curve of anti-PLA2R in diagnosing IMN were analysed based on the ELISA detection. The sensitivity, specificity, PPV, and NPV of anti-PLA2R in the diagnosis of IMN in the Chinese patients were 82.5, 75, 69.1, and 86.3% for the 2RU/ml cut-off value; 78.9, 91.7, 86.5, and 86.5% for the 2.6RU/ml cut-off value; 59.6, 95.2, 89.5, and 77.7% for the 14RU/ml cut-off value; 50.9, 96.4, 90.6, and 74.3% for the 20RU/ml cut-off value; and 47.4, 97.6, 93.1, and 73.2% for the 40RU/ml cut-off value, respectively. The area under the ROC curve was 0.879. The cut-off value of 2.6RU/ml is recommended for the use of anti-PLA2R for the diagnosis of IMN in Chinese patients based on the ELISA. Copyright © 2017.

    The objective of this study was to determine the diagnostic value of maternal serology for the diagnosis of Salmonella Dublin bovine abortion and stillbirth. A retrospective, unmatched, case-control study was carried out using twenty year's data (1989-2009) from bovine foetal submissions to an Irish government veterinary laboratory. Cases (n = 214) were defined as submissions with a S. Dublin culture-positive foetus from a S. Dublin unvaccinated dam where results of maternal S. Dublin serology were available. Controls (n = 415) were defined as submissions where an alternative diagnosis other than S. Dublin was made in a foetus from an S. Dublin unvaccinated dam where the results of maternal S. Dublin serology were available. A logistic regression model was fitted to the data: the dichotomous dependent variable was the S. Dublin foetal culture result, and the independent variables were the maternal serum agglutination test (SAT) titre results. Salmonella serology correctly classified 87% of S. Dublin culture-positive foetuses at a predicted probability threshold of 0.44 (cut-off at which sensitivity and specificity are at a maximum, J = 0.67). The sensitivity of the SAT at the same threshold was 73.8% (95% CI: 67.4%-79.5%), and the specificity was 93.2% (95% CI: 90.3%-95.4%). The positive and negative predictive values were 84.9% (95% CI: 79.3%-88.6%) and 87.3% (95% CI: 83.5%-91.3%), respectively. This study illustrates that the use of predicted probability values, rather than the traditional arbitrary breakpoints of negative, inconclusive and positive, increases the diagnostic value of the maternal SAT. Veterinary laboratory diagnosticians and veterinary practitioners can recover from the test results, information previously categorized, particularly from those results declared to be inconclusive. © 2017 Blackwell Verlag GmbH.

    Serum carcinoembryonic antigen (CEA) and serum squamous cell carcinoma antigen (SCC Ag) levels have been reported to be useful as prognostic factors, indicators of clinical response, and predictors for recurrence in patients with lung cancer treated by surgery or chemotherapy. We investigated whether pretreatment serum CEA and SCC Ag levels were useful as independent prognostic factors in patients with stage I to III non-small cell lung cancer who were treated with radiation therapy alone. The serum CEA and SCC Ag levels were measured in 158 and 47 patients, respectively, before radiation therapy. Serum CEA and SCC Ag levels were measured by sandwich radioimmunoassay using the CEA-RIA (radioimmunoassay) kit and the SCC-RIA kit. Serum CEA and SCC Ag levels were above reference values in 19% and 30% of the patients, respectively. The 5-year survival rates were significantly better for patients with a negative SCC Ag result than for those with positive SCC Ag levels (p=0.0001), though no significant difference in survival rates was seen by CEA positivity (p=0.25). SCC Ag positivity (p=0.0006) and stage (p=0.04) were the important prognostic factors, as determined by multivariate analyses. Pretreatment serum SCC Ag level may be useful as an independent prognostic factor in patients with stage I to III non-small cell lung cancer who are treated with radiation therapy alone. (author)

    The purpose of this study was to evaluate the clinical value of diffusion-weighted imaging (DWI) and dynamic magnetic resonance imaging (MRI) in combination with T 2 -weighted imaging (T 2 W) for the detection of prostate cancer. Eighty-three patients with elevated serum levels of prostate-specific antigen (PSA) (>4.0 ng/mL) were evaluated by T 2 W, DWI, and dynamic MRI at 1.5T prior to needle biopsy. The data from the results of the T 2 W alone (protocol A), combination of T 2 W and DWI (protocol B), and combination of T 2 W+DWI and dynamic MRI (protocol C) were entered into a receiver operating characteristic (ROC) analysis. Prostate cancer was detected by pathology in 44 of 83 patients. The sensitivity, respective specificity, accuracy, and Az (the area under the ROC curve) for the detection of prostate cancer were 73%, 54%, 64%, and 0.71 in protocol A; 84%, 85%, 84%, and 0.90 in protocol B; and 95%, 74%, 86%, and 0.97 in protocol C. The sensitivity, specificity, and accuracy were significantly different among the 3 protocols (p 2 W, DWI, and dynamic MRI may be valuable for detecting prostate cancer and avoiding unnecessary biopsy.

    We investigated the expression and clinical value of the soluble major histocompatibility complex class I-related chain A (sMICA) molecule in the serum of patients with renal tumors. Sixty patients diagnosed with renal tumors were enrolled in the experimental group, whereas 20 healthy volunteers served as the control group. The sMICA levels were measured via enzyme-linked immunosorbent assay, and the results were analyzed in combination with data from pathol-ogy examination. The experimental group had a statistically significant higher sMICA level (P < 0.05) than the control group. The sMICA level was higher in patients with malignant tumors than in those with be-nign tumors. We also observed a positive relationship among different tumor-node-metastasis (TNM) pathological stages with more advanced diseases exhibiting higher sMICA levels. As a tumor-associated antigen, MICA has a close relationship with renal tumorigenesis and immune es-cape. Our results indicated that sMICA levels were related to tumor pathol-ogy, TNM stage, and metastasis. Therefore, sMICA might be a potential marker for tumor characteristics, prognosis, and recurrence prediction.

    Cytokeratin 18 (CK18), a type I cytokeratin of the intermediate filament family, has been associated with the prognosis of cancer patients for decades. However, its exact role in predicting the clinical outcome of breast cancer remains controversial. To comprehensively investigated the prognostic value of CK18 in breast cancer, a systematically meta-analysis was conducted to explore the association between CK18 expression and overall survival. Literature collection was conducted by retrieving electronic databases Pubmed, Cochrane Library, Web of Science, EMBASE, and OVID completely (up to January 1, 2017). Nine relevant studies with 4857 cases assessing the relationship between CK18 high expression and the outcome of breast cancer patients were enrolled in our analysis. The results indicated that the high level of CK18 expression was significantly associated with overall survival of breast cancer patients via a specimen-depended manner. Reports which used serum to detect the expression of CK18 predicted a poor outcome of breast cancer (HR = 1.24, 95%CI: 1.11-1.38, P present study demonstrated that CK18 might be served as a novel biomarker to predict clinicopathological features and the outcome of breast cancer. © 2018 The Author(s).

    Serum HBV large surface protein (HBV-LP) is an envelope protein that has a close relationship with HBV DNA level. This study is to explore the prediction value of HBV-LP in different phase of HBV infection and during antiviral therapy in chronic hepatitis B (CHB) patients. A retrospective study was conducted in 2033 individuals, which included 1677 HBV infected patients in different phases and 356 healthy controls. HBV-LP, HBV serum markers and HBV DNA were detected by ELISA, CMIA and qRT-PCR, respectively. 85 CHB patients receiving PegIFNα or ETV were divided into virological response (VR) and partial virological response (PVR). The dynamic changes of HBV DNA and HBV-LP were observed. The level of HBV-LP in 2033 individuals was shown as: HBeAg-positive hepatitis > HBeAg-positive infection > HBeAg-negative hepatitis > HBeAg-negative infection > healthy controls. HBV-LP was positive in all patients whose HBV DNA > 1.0E + 06 IU/ml. When HBsAg was 1000 IU/ml, HBV DNAs were all negative if HBV-LP HBV-LP with HBV DNA was 100% in case of HBV-LP > 4.0 S/CO in HBeAg-positive patients and HBV-LP > 2.0 S/CO in HBeAg-negative ones. During antiviral therapy, baseline HBV-LP was lower in VR patients than that in PVR patients. The optimal cut-off points to predict VR by baseline HBV-LP were 32.4 and 28.6 S/CO for HBeAg-positive and HBeAg-negative hepatitis patients, respectively. HBV-LP may be a useful marker for distinguishing the different phases of HBV infection. Moreover, baseline HBV-LP level can be used for predicting VR of CHB patients. Copyright © 2018 Elsevier B.V.

    Limited data are available for the diagnostic value, and for the diagnostic sensitivity and specificity of joint detection of serum lactate dehydrogenase (sLDH)/pleural fluid adenosine deaminase (pADA) and pleural fluid carcinoembryonic antigen (pCEA) in malignant pleural effusion (MPE). We collected 987 pleural effusion specimens (of which 318 were malignant pleural effusion, 374 were tubercular pleural effusion, and 295 were parapneumonic effusion specimens) from the First Affiliated Hospital of Wenzhou Medical University from July 2012 to March 2016. The pADA, sLDH, pleural fluid LDH (pLDH), serum C-reactive protein (sCRP), pleural fluid protein, pCEA, white blood cell (WBC), and red blood cell (RBC) were analyzed, and the clinical data of each group were collected for statistical analysis. The level of sLDH/pADA, pCEA, and RBC from the MPE group was markedly higher than the tuberculosis pleural effusion (TB) group (Mann-Whitney U=28422.000, 9278.000, 30518, P=.000, .000, .000) and the parapneumonic pleural fluid group (Mann-Whitney U=5972.500, 7113.000, 36750.500, P=.000, .000, .000). The receiver operating characteristic curve ROC showed that the area under the ROC curve (AUC) (=0.924, 0.841) of pCEA and sLDH/pADA (cutoff=4.9, 10.6) were significantly higher than other markers for the diagnosis of MPE. Thus, joint detection of pCEA and sLDH/pADA suggested that the sensitivity, specificity, and AUC was 0.94, 81.70, and 94.32 at the cutoff 0.16 and diagnostic performance was higher than pCEA or sLDH/pADA. Joint detection of sLDH/pADA and pCEA can be used as a good indicator for the identification of benign and MPE with higher sensitivity and specificity than pCEA or sLDH/pADA. © 2016 Wiley Periodicals, Inc.

    Objective: To investigate the changes of serum levels of collagen type IV(IV-C), procollagen type III (PC III), hyaluronic acid (HA), laminin (LN) and prolidase (PLD) and their relationship with hepatic fibrosis in patients with B hepatitis of different types. Methods: Serum levels of IV-C, PC III, HA, LN and PLD were measured with RIA in 39 controls and 103 patients with HBV infection of various types (including acute hepatitis AH n=19, chronic persistent hepatitis CPH n=29, Chronic active hepatitis CAH n=25 and liver cirrhosis LH n=30. Degree of hepatic fibrosis (Grade 0-4) was ascertained with liver biopsy in 35 patients (CAH16, LC19) and correlationship with the corresponding levels of these 5 serum markers was steadied. Results: 1) Serum levels of IV-C, PC III, HA, LN and PLD were significantly higher in patients with CAH and LC than those in other patients and controls (P 0.05). 3) Serum levels of these markers were all positively correlated with the degree of hepatic fibrosis noted in the biopsy specimens obtained from patients with CAH (n=16) and LC (n=19) (r=+0.64 - + 0.89, P<0.01). Conclusion: Serum levels of these markers could reflect the degree of hepatic fibrosis and severity of liver damage; determination of which was of diagnostic and even prognostic value. HA and LN appeared to be better correlated with degree of hepatic fibrosis than the remaining three markers did. (authors)

    This study aims to understand the diagnostic value of serum tumor markers carcinoembryonic antigen (CEA), cancer antigen 19-9 (CA19-9), cancer antigen 125 (CA125), cancer antigen 15-3 (CA15-3), and tissue polypeptide-specific antigen (TPS) in metastatic breast cancer (MBC). A total of 164 metastatic breast cancer patients in Shanxi Cancer Hospital were recruited between February 2016 and July 2016. 200 breast cancer patients without metastasis in the same period were randomly selected as the control group. The general characteristics, immunohistochemical, and pathological results were investigated between the two groups, and tumor markers were determined. There were statistical differences in the concentration and the positive rates of CEA, CA19-9, CA125, CA15-3, and TPS between the MBC and control group (Ptumor marker at 56.7% and 97.0%, respectively. In addition, two tumor markers were used for the diagnosis of MBC and the CEA and TPS combination had the highest diagnostic sensitivity with 78.7%, while the CA15-3 and CA125 combination had the highest specificity of 91.5%. Analysis of tumor markers of 164 MBC found that there were statistical differences in the positive rates of CEA and CA15-3 between bone metastases and other metastases (χ 2 =6.00, P=0.014; χ 2 =7.32, P=0.007, respectively). The sensitivity and specificity values of the CEA and CA15-3 combination in the diagnosis of bone metastases were 77.1% and 45.8%, respectively. The positive rate of TPS in the lung metastases group was lower than in other metastases (χ 2 =8.06, P=0.005).There were significant differences in the positive rates of CA15-3 and TPS between liver metastases and other metastases (χ 2 =15.42, Ptumor markers have varying diagnostic value.

    Physicians compared clinical history, examination, and laboratory data on 10 pregnant women at various gestational ages with intact membranes till labor began (controls) with data on 25 pregnant women also at various gestational ages who experienced premature rupture of membranes (PROM) (cases) to determine the value of C-reactive protein (CRP) in maternal and cord blood as a predictor of chorioamnionitis in women with PROM. 32% of cases had clinical chorioamnionitis and 44% histopathological chorioamnionitis. The maternal serum level of CRP in cases with and without chorioamnionitis at delivery was statistically higher than that of the controls (45.82 CRP mg/L and 9.71 CRP mg/L vs. 6.6 CRP mg/l; P.05). Further the CRP level in cord blood of cases with chorioamnionitis also stood much higher than that of the controls (p.001). In addition, the total leukocytic count (TLC) for cases with chorioamnionitis at delivery was much higher than it was for the control group at delivery (12,510 TLC/cubic mm vs. 18,231 TLC/cubic mm; p.05). A significant difference also existed between the temperature of the cases with chorioamnionitis and that of the controls (37.11 degrees Celsius vs. 63.97 degrees Celsius; p.05). Sensitivity and specificity tests showed that CRP 24 mg/L was the most reliable predictor of chorioamnionitis (100% and 93.3% respectively) followed by TLC (77.8% and 92.8% respectively) then temperature (55.6% and 78.6% respectively). Thus CRP can be used to predict premature delivery and simultaneously reduces unnecessary premature delivery of many PROM cases which occur due to fear of developing infections in both the mother and the fetus.

    Effective antiviral therapy plays a key role in slowing the progression of chronic hepatitis B (CHB). Identification of serum indices, including hepatitis B e antigen (HBeAg) expression and seroconversion, will facilitate evaluation of the efficacy of antiviral therapy in HBeAg-positive CHB patients. The biochemical, serological, virological parameters, and the frequency of circulating CD4CD25 regulatory T cell (Treg) in 32 patients were measured at baseline and every 12 weeks during 96 weeks of tenofovir disoproxil fumarate (TDF) treatment. The relationship between the hepatitis B virus (HBV) deoxyribonucleic acid (DNA) and Treg and alanine aminotransferase (ALT) levels was analyzed, respectively. The molecular profiles of T-cell receptor beta variable chain (TRBV) were determined using gene melting spectral pattern. For the seroconverted 12 patients, ALT declined to normal levels by week 24 and remained at this level in subsequent treatment; moreover, the predictive cutoff value of ALT for HBeAg seroconversion (SC) was 41.5 U/L at week 24. The positive correlation between HBV DNA and Treg and ALT was significant in SC patients, but not in non-SC patients. Six TRBV families (BV3, BV11, BV12, BV14, BV20, and BV24) were predominantly expressed in SC patients at baseline. The decline of ALT could be used to predict HBeAg seroconversion for CHB patients during TDF treatment. In addition, the profile of Tregs and TRBVs may be associated with HBeAg seroconversion and could also be a potential indicator for predicting HBeAg SC and treatment outcome for CHB patients.

    Full Text Available BACKGROUND: The Cockcroft-Gault formula (CGF is used to estimate the glomerular filtration rate (GFR based on serum creatinine (Cr levels, age and sex. A new formula developed by the Modification of Diet in Renal Disease (MDRD Study Group, based on the patient’s Cr levels, age, sex, race and serum urea nitrogen and serum albumin levels, has shown to be more accurate. However, the best formula to identify patients with advanced liver disease (ALD and moderate renal dysfunction (GFR 60 mL/min/1.73 m2 or less is not known. The aim of the present study was to compare calculations of GFR, using published formulas (excluding those requiring urine collections with standard radionuclide measurement of GFR in patients with ALD.

    Full Text Available Abstract Backround The aim of the present study was to assess the effects of zinc or copper and polyphenolic compounds on the 8-isoprostaglandin F2α concentration in the serum and urine of rats with mammary cancer (adenocarcinoma induced with 7,12-dimethylbenz[a]antracene. The research focused on the kinetics of alterations in urinary 8-isoPGF2α at the early stage of carcinogenesis as well as the influence of dietary factors on the process. The impact of selected compounds on the intensity of DMBA - induced carcinogenesis was also assessed. Result and conclusions Administration of DMBA, a compound that inducers mammary tumors in experimental animals, increased the serum and urinary 8-isoPGF2α levels in study rats. In the rat model, diet supplementation with zinc, combined with selected polyphenolic compounds (resveratrol or genistein yielded a statistically significant decrease in the rat serum and urinary biomarker concentration with a simultaneously significant stimulation of carcinogenesis. The results indicate that there is an inverse correlation between the intensity of DMBA-induced carcinogenicity and the level of 8-isoPGF2α in urine and serum of rats.

    To date cytokines profile in AEDS is poorly described in children. We evaluated the interleukin (IL)-17, IL-23, and IL-10 levels in atopic eczema/dermatitis syndrome (AEDS) children and healthy controls, in atopic AEDS (aAEDS) and nonatopic (naAEDS) subtypes and their relationship with disease severity. A total of 181 children with aAEDS and 93 healthy children were evaluated. According to the skin-prick test (SPT) for allergens and serum total IgE, all patients were subdivided in two groups: 104 aAEDS and 77 naAEDS. In all patients, serum IL-17, IL-23, and IL-10 levels were detected. Serum IL-17 and IL-23 levels were significantly higher, and serum IL-10 levels were significantly lower in AEDS children than healthy group (p children with only allergic sensitization. Our study confirms the role of IL-17, IL-23, and IL-10 and their relationship with the severity of AEDS. We firstly found a correlation between high IL-17/IL-23 axis levels and different phenotypes of AEDS in children, suggesting its role as marker of "atopic march" and disease severity.

    BAL lymphocyte percentages, quantitated gallium-67 lung uptake, and SACE levels have all been proposed as measures of disease activity in sarcoidosis. We analyzed 32 paired sera and BAL fluids from sarcoidosis patients by high-resolution agarose electrophoresis to look for protein changes characteristic of systemic or local inflammation and compared the results with those from the above tests. Nine patients (group 1) had serum inflammatory protein changes and increased total protein, albumin, beta 1-globulin (transferrin), and gamma-globulin levels in fluid recovered by BAL. Thirteen patients (group 2) had normal protein levels in sera but abnormal protein levels in BAL specimens. Ten patients (group 3) had normal protein levels in sera and in BAL specimens. Patients in groups 1 and 2 had a disproportionate increase in beta 1-globulin (transferrin) and gamma-globulin levels in their BAL specimens. The BAL lymphocyte percentage changes paralleled the BAL protein level changes, suggesting relationships among the immunoregulatory role of these cells, increased local immunoglobulin synthesis, and the pathogenesis of altered alveolar permeability. Gallium-67 uptake was highest in patients with serum inflammatory protein changes. Thus, systemic inflammation may facilitate pulmonary gallium-67 uptake, possibly by changes in BAL fluid or serum transferrin saturation and/or kinetics. SACE levels showed no relationship to changes in the levels of serum or BAL proteins. These data suggest that the various proposed measures of disease activity reflect different aspects of inflammation in sarcoidosis

    Postoperative infectious complications are one of the most important problems in surgical treatment of colorectal cancer (CRC), being present in up to 40% of patients. The aim of this paper was to establish the significance of serial measurement of C-reactive protein (CRP) in serum and matrix metalloproteinase-9 (MMP-9) in drainage fluid for the detection of infectious complications and anastomotic leakage (AL) in patients with colorectal resection. CRP and MMP-9 values in serum and drainage fluid, respectively, were measured on the first, third, fifth, and seventh postoperative day (POD) in 150 patients with colorectal resection and primary anastomosis. The values obtained were compared between the patients without complicatons and those with surgical site and remote infections and AL. Surgical site infections (SSIs) were observed in 41 (27.3%), and remote infections in 10 (6.7%) patients. Clinically evident AL was observed in 15 (10/6) patients. In 82% of the patients with SSIs, serum CRP value on POD 5 exceeded 82 mg/L, with 81% specificity. AL was reported in 85% and 92% of the patients on PODs 5 and 7, respectively, with CRP values of 77 mg/L and 90 mg/L, respectively. The specificity was 77% for POD 5 and 88% for POD 7. All the patients with CRP values exceeding 139 mg/L on POD 5 had some of SSIs and/or AL. The mean values of MMP-9 were not statistically different between the group without complications (n = 99) and the group with AL (n = 15). Serial measurement of CRP is recommended for screening of infectious complications of colorectal resection. Patients with CRP values above 139 mg/L on POD 5 cannot be discharged from hospital, and require an intensive search for infectious complications, particularly AL. MMP-9 measurement in drainage fluid is not relevant in the detection of AL in patients with colorectal resection.

    Objective: To investigate the value of 99 Tc m -HL91 hypoxia imaging combined the detection of serum neuron-specific enolase (NSE), carcinoembryonic antigen(CEA) and cytokeratin 19 fragment (CYFRA21-1) in the diagnosis of lung cancer. Methods: 63 patients with lung neoplasm were carried out 99 Tc m -Hail hypoxia imaging, and the serum tumor markers levels of Nose, Cea and CYFRA21-1 were detected. The sensitivity, specificity and accuracy of each and combined method were calculated respectively and compared with each other. Results: The sensitivity,specificity and accuracy in diagnosis of lung cancer with 99 Tc m -HL91 hypoxia imaging were 85.4%, 100% and 88.9% respectively; and with serum tumor markers NSE, CEA and CYFRA21-1 detection were 72.9%, 86.7% and 76.1% respectively. Compared with the detection of serum tumor marker levels of NSE, CEA and CYFRA21-1, 99 Tc m -HL91 hypoxia imaging had the higher sensitivity and specificity,and similar accuracy. The sensitivity, specificity and accuracy of combined two methods in diagnosis of lung cancer were 95.8%, 86.7% and 93.6% respectively. The sensitivity and accuracy of the combined method were significantly increased than single method (P 0.05). Conclusion: 99 Tc m -HL91 hypoxia imaging and the detection of serum level of NSE, CEA and CYFRA21-1 have an important diagnostic value, and their combination could improve the sensitivity and accuracy in the diagnosis of lung cancer.

    The routine assessment of day 3 serum progesterone prior to initiation of ovarian hyper-stimulation with the use of GnRH antagonists is under debate. In this study, we evaluated the clinical utility of this policy. Retrospective cohort study of women undergoing in vitro fertilization (IVF) with the use of GnRH antagonists aimed at determining the frequency of cases with progesterone levels exceeding the recommended threshold of 1,660 pg/ml and at evaluating whether this assessment may be predictive of pregnancy. Serum progesterone exceeded the recommended threshold in one case (0.3%, 95% CI 0.01-1.5). The median (interquartile range) basal progesterone in women who did (n = 95) and did not (n = 217) become pregnant were 351 (234-476) and 380 (237-531) pg/ml, respectively (p = 0.28). The 90th percentile of the basal progesterone distribution in women who became pregnant was 660 pg/ml. Cases with serum progesterone exceeding this threshold in successful and unsuccessful cycles were 10 (10%) and 30 (14%), respectively (p = 0.47). The capacity of basal progesterone to predict pregnancy was evaluated using receiver operating characteristic curve (area under the curve = 0.54, 95% CI 0.47-0.61, p = 0.28). No graphically evident threshold emerged. Routine day 3 serum progesterone assessment in IVF cycles with the use of GnRH antagonists is not justified. Further evidence is warranted prior to claiming its systematic use. © 2016 S. Karger AG, Basel.

    Objective; To investigate the clinical usefulness of combined determination of serum rheumatic factor (RF), anti-keratin antibody (AKA) and anti-cyclic citrullinated peptide antibody (anti-CCP antibody) levels for early diagnosis in patients with rheumatoid arthritis (RA). Methods: Serum RF ( with rate-nephelometry), AKA (with indirect immuno-fluorescence) and anti-CCP antibody (with ELISA) levels were determined in 40 patients with RA, 30 patients with SLE and 30 controls. Results: For diagnosis of RA; the sensitivity and specificity of RF was 70.0% and 90.0% respectively, the sensitivity and specificity of AKA was 35.0% and 96.7%, the sensitivity and specificity of anti-CCP-antibody was 85% and 93.3% respectively. With combined determination of RF, AKA and anti-CCP antibody, the sensitivity and specificity would be the highest, being 97.07 and 99.8% respectively. Conclusion: RF, AKA and anti-CCP antibody were useful diagnostic serum markers for rheumatoid arthritis and combined determination of these markers would be very useful for early diagnosis.

    This study was conducted to determine the utility of digital rectal examination (DRE), transrectal ultrasonography (TRUS) and serum prostate-specific antigen (PSA) in the diagnosis of prostate cancer in men in Arabia, an are of the world with a relatively low incidence of this disease. 329 patients suspected of having prostate cancer on account of raised serum PSA level (>4 ng/ml), DRE or TRUS findings, underwent TRUS-guided prostate biopsy. Raised PSA individually as well as combined, or a lesion suspicious of carcinoma on DRE or TRUS was recorded as PSA (+), DRE (+) or TRUS (+), respectively. The contribution of DRE, TRUS and serum PSA to the diagnosis of prostate cancer was analysed. Of the 329 patients who had prostate biopsies 109 cases (33.1%) had PCa. Of these 109 patients 56 (51%) had DRE (+), 77 (42%) ha d TRUS (+) and 49 (66%) had both DRE (+) and TRUS (+). Statistical analysis revealed that DRE (+) tripled the probability for cancer. PSA over a range of 10-50 ng/mL demonstrated an increasing cancer probability ranging from 2to 3 fold. TRUS (+) was only significantly associated with cancer risk if PSA was elevated. The presence of all three factors increased the cancer probability by 6 to 7 fold. TRUS findings are dependent on PSA for interpretation while DRE (+) with elevated PSA makes PCa more likely.

    The zinc ion is essential for the living organism. Many pathological conditions have been described as a consequence of zinc deficiency. As zinc constitutes less than 0.01 per cent of the body weight, it conventionally belongs to the group of trace elements. The method of atomic absorption spectrophotometry is used to measure the concentration of zinc in serum and urine from healthy persons. The assumptions of the method is discussed. The importance of proteinbinding, diet and the diurnal variation of serum zinc concentration is presented. Serum versus plasma zinc concentration is discussed. Reference serum zinc values from 104 normal subjects are given. Zinc in serum is almost entirely bound to proteins. A preliminary model for the estimation of the distribution of zinc between serum albumin and α 2 -macroglobulin is set up. This estimate has been examined by an ultracentrufugation method. The binding of zinc to a α 2 -macroglobulin in normal persons is appoximately 7 per cent, in patients with cirrhosis of the liver of alcoholic origin approximately 6 per cent, in patients with insulin dependent diabetes mellitus approximately 5 per cent, and in patients with chronic renal failure approximately 2 per cent. It is concluded, therefore, that for clinical purposes it is sufficient to use the concentration of total serum zinc corrected for the concentration of serum albumin. (author)

    The effect of radioiodine ( 131I ) in Graves disease (GD) is probably due to the direct physical destruction of thyrocytes by beta radiation, and by the indirect action through stimulation of apoptosis in these cells. The aim of our study was to investigate the changes in serum concentrations of sFas and sFasL as stimulators of apoptosis, and Bcl-2 as an inhibitor of apoptosis in patients with GD following 131I administration. The study was performed on 30 patients with GD (29 female and 1 male aged 25-45). All patients were euthyroid (biochemical and clinical) prior to radioiodine therapy. The target absorbed dose ranged between 90 and 160 Gy. We assessed markers of apoptosis and hormone concentrations (fT3, fT4 and TSH) in the following manner: before 131I administration, then two weeks, one month, two, three, four, and five months after 131I administration. After four months, the concentrations of sFas and sFasL rose by 50% and decreased during the next month. Pretherapeutic concentrations of Bcl-2 were elevated, and peaked two weeks after ingestion, showing a gradual decrease with time. We found a significant increase in serum TSH, and a decrease of fT3 and fT4 concentrations by the end of the third month of radioiodine therapy. Decreases in serum levels of sFas and sFasL and increases of Bcl-2 are regarded as characteristic for GD patients before radioiodine therapy. Radioiodine therapy reverses the ratio of estimated markers after four months. The concentrations of hormones reflect actual thyroid function, whereas concentrations of markers of apoptosis may suggest morphological changes. (author)

    Conclusions. The level of IL-8 below 100 pg/ml in the follicular fluid of the infertile patients with PCOS, as well as the increase in serum IL-6 of more than 2.5 pg/ml in the women with tubal infertility can be recommended as predictors of the negative outcome of the IVF programs . When obtaining such results during the IVF program, it is advisable to resolve the issue of delayed transfer of embryos for the purpose of conducting an additional course of immunomodulatory therapy in the framework of preimplantation preparation.

    To investigate the concentration of alphafetoprotein AFP in different liver diseases and above all in liver cancer the immunoradiometric assay was utilized. The results of AFP studies were compared with regeneration index, blastic T lymphocytes transformation as well as other morphological and biochemical data. The results of the investigations indicated that: 38% of chronic benign hepatopathies displayed the values of serum AFP in normal ranges, 54% were in the range of 41 - 200ng/ml, and 8% showed 200 and more ng/ml. The most important conclusion from the work performed was that the elevation of serum AFP level in the evaluation of chronic hepatopathies, especially in cirrhoses, appears as an index of malignancy

    We report an IgA-lambda type M-protein in which the IgA concentration differed from the values of M-protein by serum protein electrophoresis found in a 53-year-old man with multiple myeloma. The M-protein value as determined by serum protein electrophoresis was 6,170 mg/dl. However, the serum IgA concentration was 3,052 mg/dl by turbidimetric immunoassay. Immuno-fixation electrophoresis using IgA subclass antisera revealed that this M-protein was the IgA2-lambda type. Western blotting analysis showed that the IgA2 molecules were composed of two approximately 68 kDa alpha 2 chains and two 28 kDa lambda chains. In addition the free lambda chain band was detected at the position of 28 kDa without 2-mercaptoethanol(2-ME) even though the patient IgA was purified. Since it is known that IgA2m(1) allotype easily release light chains from the IgA molecules in SDS-PAGE without 2-ME, we speculated that in this patient the IgA was the IgA2m(1) allotype. After peripheral blood stem cell transplantation(PBSCT), immunofixation electrophoresis of the patient serum revealed not only the bands of IgA2-lambda type M-protein, but also three bands of IgG1-kappa type M-protein in the gamma region.

    To examine whether the combined detection of serum tumor markers (CEA, CA72-4, CA19-9, CA15-3 and CA12-5) improves the sensitivity and accuracy in the diagnosis of gastric cancer (GC). An automatic chemiluminescence immune analyzer with matched kits was used to determine the levels of serum CEA, CA72-4, CA19-9, CA15-3, and CA12-5 in 87 patients with gastric cancer (GC group), 60 patients with gastric benign diseases (GBD group) who were hospitalized during the same period, and 40 healthy subjects undergoing a physical examination. The values of these 5 tumor markers in the diagnosis of gastric cancer were analyzed. The levels of serum CEA, CA72-4, CA19-9, and CA12-5 were higher in the GC group than in the GBD group and healthy subjects, and these differences were significant ( P 0.05). The combined detection of CEA, CA72-4, CA19-9, and CA12-5 had a higher diagnostic value for gastric cancer than did single detection, and the positive detection rate of the combined detection of the four tumor markers was 60.9%. The diagnostic power when using the combined detection of CA72-4, CEA, CA19-9, and CA12-5 was the best. The combined detection of serum CA72-4, CEA, CA19-9 and CA12-5 increases the sensitivity and accuracy in the diagnosis of GC and can thus be considered an important tool for early diagnosis. © 2017 by the Association of Clinical Scientists, Inc.

    To explore the immune effect of fufangjiakang tablets (FJT) on the treatment of Graves' disease with 131 I by observing the changes of serum TGAb, TMAb and TRAb levels before or after 131 I treatment, 121 patients with Graves' disease were divided into two groups, 58 patients treated with 131 I alone as control group and 61 patients treated with 131 I combined and FJT as research group. The patients were followed up in 2, 4 and 12 months after treatment. The levels of serum TGAb, TMAb and TRAb in patients were measured before and after treatment. The results showed that the positive cases of TGAb and TMAb in research and control group before the treatment were 9 and 8 cases separately, the cases of TGAb and TMAb changed to negative were 4 (44.4%) and 1 (12.5%) after treatment of 12 months. The rate in research group was higher than that in control group (P 131 I and FJT could increase the negative rates of TGAb and TMAb levels in patients, and reduce the levels of TRAb more quickly. Therefore it could reinforce the immune regulating function of the patients with Graves' disease. (authors)

    Serum C-reactive protein (CRP) associates with radiographic progression in patients with ankylosing spondylitis (AS) untreated with tumor necrosis factor (TNF) antagonists. We assessed correlations between serum CRP and radiographic progression/magnetic resonance imaging (MRI)-detected inflammation after 2 years of anti-TNF therapy. Patients with active AS receiving golimumab (GOL)/placebo through Week 16 (early escape) or Week 24 (crossover by design), followed by GOL through 4 years, had sera/images obtained through Week 208. Lateral spinal radiographs and spinal MRI were scored with the modified Stoke AS Spine Score (mSASSS) and the AS spine MRI activity (ASspiMRI-a) score, respectively. ANOVA assessed differences based on CRP levels and mSASSS progression. The relationships between CRP levels and mSASSS/ASspiMRI-a were assessed by Spearman correlation and logistic regression. Of the randomized GO-RAISE patients, 299 (84.0%) had pre- and posttreatment spinal radiographs. Larger proportions of patients with Week 104 CRP ≥ 0.5 mg/dl (n = 47) versus formation risk. Elevated CRP after 2 years of anti-TNF treatment correlated with greater radiographic progression risk at 4 years. Elevated CRP at baseline or Week 14/Week 24 of anti-TNF treatment weakly predicted subsequent radiographic progression and modestly predicted residual spinal inflammation in patients with AS treated with anti-TNF. Findings are useful regarding new treatment options in patients treated with anti-TNF. ClinicalTrials.gov: NCT00265083.

    To identify thresholds of BMI at which similar levels of serum lipids occur in Inuit and in non-Inuit as the impact of obesity on metabolic risk factors differ in Inuit compared to other ethnic groups. Published comparative data among Inuit and non-Inuit whites on BMI and HDL-cholesterol and triglyceride were identified for analysis. A literature search was done for BMI, lipids, Inuit and Greenland or Canada. Studies with data on triglycerides and HDL-cholesterol in Inuit and non-Inuit Caucasians were selected and data were retrieved. Regression equations were computed for BMI and HDL-cholesterol and BMI and triglycerides. BMI for similar levels of lipids in Inuit and non-Inuit and ratios of Inuit/non-Inuit BMI's were calculated. At BMI 25 kg/m2 HDL-cholesterol was 1.7/1.6 mM in Greenland Inuit/non-Inuit women and 1.7/1.5 mM in men in a major comparative study. HDL cholesterol decreased by 0.09 for each 1 kg/m2 increase in BMI. Serum triglycerides were 1.0/1.1 mM for Greenland Inuit/non-Inuit women and 0.9/ 1.4 mM for men at BMI 25 kg/m2. Slopes were around 0.1. A comparative study in Canadian Inuit/non-Inuit gave similar results. The BMI levels required for similar HDL-cholesterol or triglycerides were around 27.5 kg/m2, and Inuit/non-Inuit BMI-ratios were around 1.1. The same degree of dyslipidaemia was seen when Inuit had a 10% higher BMI compared to non-Inuit. This may support the establishment of Inuit-specific BMI cut-offs for the purposes of health screening and population health surveillance.

    Glucose utilization by the erythrocytes, lactic acid concentration in the blood and erythrocytes, and haematocrit value were determined before exercise and during one hour rest following maximal exercise in 97 individuals of either sex differing in physical efficiency. In the investigations reported by the author individuals with strikingly high physical fitness performed maximal work one-third greater than that performed by individuals with medium fitness. The serum concentration of lactic acid was in all individuals above the resting value still after 60 minutes of rest. On the other hand, this concentration returned to the normal level in the erythrocytes but only in individuals with strikingly high efficiency. Glucose utilization by the erythrocytes during the restitution period was highest immediately after the exercise in all studied individuals and showed a tendency for more rapid return to resting values again in individuals with highest efficiency. The investigation of very efficient individuals repeated twice demonstrated greater utilization of glucose by the erythrocytes at the time of greater maximal exercise. This was associated with greater lactic acid concentration in the serum and erythrocytes throughout the whole one-hour rest period. The observed facts suggest an active participation of erythrocytes in the process of adaptation of the organism to exercise.

    There are limited data on serum total light chain (sTLC) in lymphoma and its relative role on the outcome of diffuse large B cell lymphoma (DLBCL) patients. Blood samples from 46 cases newly diagnosed with DLBCL were collected consecutively during chemotherapy to detect sTLC, IgG, IgA, and IgM levels. Clinical data and survival outcomes were analyzed according to the results of sTLC measurements. In summary, 22 patients (47.8 %) had abnormal k or λ light chain, respectively, and 6 patients (13.0 %) had both abnormal k and λ light chains before chemotherapy. Patients with elevated k light chain more frequently displayed multiple extra-nodal organ involvement (P = 0.01) and had an inferior overall survival (OS) (P = 0.041) and progression-free survival (PFS) (P = 0.044) compared to patients with normal level of k light chain. Furthermore, patients with elevated level of both k and λ also exhibited significant association with shorter OS (P = 0.002) and PFS (P = 0.009). Both elevated k alone and concurrent elevated k and λ had independent adverse effects on PFS (P = 0.031 and P = 0.019, respectively). sTLC level was reduced gradually by treatment in this study and reached the lowest point after the fourth cycle of chemotherapy, which was consistent with the disease behavior during chemotherapy. Considering the small sample size of this study, these results should be confirmed in a larger prospective study.

    Low cardiac output syndrome is common after paediatric cardiac surgery. Previous studies suggested that hydrocortisone administration may improve haemodynamic stability in case of resistant low cardiac output syndrome in critically ill children. This study was set up to test the hypothesis that the effects of hydrocortisone on haemodynamics in children with low cardiac output syndrome depend on the presence of (relative) adrenal insufficiency. A retrospective study was done on paediatric patients who received hydrocortisone when diagnosed with resistant low cardiac output syndrome after paediatric cardiac surgery in the period from 1 November 2005 to 31 December 2008. We studied the difference in effects of treatment with hydrocortisone administration between patients with adrenal insufficiency defined as an exploratory cut-off value of total cortisol of cortisol of ≥ 100 nmol/l. A total of 62 of patients were enrolled, meeting the inclusion criteria for low cardiac output syndrome. Thirty-two patients were assigned to Group 1 (cortisol concentration and those with normal baseline cortisol levels. A cortisol value using an exploratory cut-off value of 100 nmol/l for adrenal insufficiency should not be used as a criterion to treat these patients with hydrocortisone.

    F-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography/computed tomography (PET/CT) scan and hypothyroidism. The aim was to determine whether the intensity of diffuse thyroid gland uptake on F-18 FDG PET/CT scans predicts the severity of hypothyroidism. A retrospective analysis of 3868 patients who underwent F-18 FDG PET/CT scans, between October 2012 and June 2013 in our institution for various oncological indications was done. Out of them, 106 (2.7%) patients (79 females, 27 males) presented with bilateral diffuse thyroid gland uptake as an incidental finding. These patients were investigated retrospectively and various parameters such as age, sex, primary cancer site, maximal standardized uptake value (SUVmax), results of thyroid function tests (TFTs) and fine-needle aspiration cytology results were noted. The SUVmax values were correlated with serum thyroid stimulating hormone (S. TSH) levels using Pearson's correlation analysis. Pearson's correlation analysis. Clinical information and TFT (serum FT3, FT4 and TSH levels) results were available for 31 of the 106 patients (27 females, 4 males; mean age 51.5 years). Twenty-six out of 31 patients (84%) were having abnormal TFTs with abnormal TSH levels in 24/31 patients (mean S. TSH: 22.35 μIU/ml, median: 7.37 μIU/ml, range: 0.074-211 μIU/ml). Among 7 patients with normal TSH levels, 2 patients demonstrated low FT3 and FT4 levels. No significant correlation was found between maximum standardized uptake value and TSH levels (r = 0.115, P > 0.05). Incidentally detected diffuse thyroid gland uptake on F-18 FDG PET/CT scan was usually associated with hypothyroidism probably caused by autoimmune thyroiditis. Patients should be investigated promptly irrespective of the intensity of FDG uptake with TFTs to initiate replacement therapy and a USG examination to look for any suspicious nodules

    The early decline profile of alpha-fetoprotein (AFP) and human chorionic gonadotropin (hCG) in patients with nonseminomatous germ cell tumors (NSGCT) treated with chemotherapy may be related to the risk of relapse. We assessed the predictive values of areas under the curve of hCG (AUC(hCG)) and AFP (AUC(AFP)) of modeled concentration-time equations on progression-free survival (PFS). Single-center retrospective analysis of hCG and AFP time-points from 65 patients with IGCCCG intermediate-poor risk NSGCT treated with 4 cycles of bleomycin-etoposide-cisplatin (BEP). To determine AUC(hCG) and AUC(AFP) for D0-D42, AUCs for D0-D7 were calculated using the trapezoid rule and AUCs for D7-D42 were calculated using the mathematic integrals of equations modeled with NONMEM. Combining AUC(AFP) and AUC(hCG) enabled us to define 2 predictive groups: namely, patients with favorable and unfavorable AUC(AFP-hCG). Survival analyses and ROC curves assessed the predictive values of AUC(AFP-hCG) groups regarding progression-free survival (PFS) and compared them with those of half-life (HL) and time-to-normalization (TTN). Mono-exponential models best fit the patterns of marker decreases. Patients with a favorable AUC(AFP-hCG) had a significantly better PFS (100% vs 71.5%, P = .014). ROC curves confirmed the encouraging predictive accuracy of AUC(AFP-hCG) against HL or TTN regarding progression risk (ROC AUCs = 79.6 vs 71.9 and 70.2 respectively). Because of the large number of patients with missing data, multivariate analysis could not be performed. AUC(AFP-hCG) is a dynamic parameter characterizing tumor marker decline in patients with NSGCT during BEP treatment. Its value as a promising predictive factor should be validated.

    Immunoglobulin E-mediated allergy to cow's milk protein (CMP) tends to subside over years of follow-up. The gold standard for detecting such allergy has been the oral challenge test. The development of some other test for determining the correct timing of the oral challenge test would avoid unnecessary patient discomfort. The aim of this study was to determine whether monitoring cow's milk (CM) specific IgE levels over time can be used as a predictor for determining when patients develop clinical tolerance. A prospective 4-year follow-up study was made of 170 patients with IgE-mediated allergy to CMP, involving periodic evaluations (12, 18, 24, 36 and 48 months) with the determination of casein and CM specific IgE on each visit, along with CM challenge testing. ROC curves were used to analyse the sensitivity, specificity and predictive values of the casein and CM specific IgE levels versus the challenge test outcomes at the different moments of follow-up. In the course of follow-up, 140 infants (82 %) became tolerant. Specific IgE levels to CM: 2.58, 2.5, 2.7, 2.26, 5 kU(A)/l and to casein: 0.97, 1.22, 3, 2.39, 2.73 kU(A)/l, respectively, predicted clinical reactivity (greatest diagnostic efficiency values) at the different analysed moments of follow-up (12, 18, 24, 36 and 48 months). Quantification of CMP specific IgE is a useful test for diagnosing symptomatic allergy to CM in the paediatric population, and could eliminate the need to perform oral challenges tests in a significant number of children.

    Selective Internal Radiation Therapy (SIRT) is a new and effective locoregional anticancer therapy for colorectal cancer patients with liver metastases. Markers for prediction of therapy response and prognosis are needed for the individual management of those patients undergoing SIRT. Blood samples were prospectively and consecutively taken from 49 colorectal cancer patients with extensive hepatic metastases before, three, six, 24 and 48 h after SIRT to analyze the concentrations of nucleosomes and further laboratory parameters, and to compare them with the response to therapy regularly determined 3 months after therapy and with overall survival. Circulating nucleosomes, cytokeratin-19 fragments (CYFRA 21-1), carcinoembryonic antigen (CEA), C-reactive protein (CRP) and various liver markers increased already 24 h after SIRT. Pretherapeutical levels of CYFRA 21-1, CEA, cancer antigen 19-9 (CA 19-9), asparate-aminotransferase (AST) and lactate dehydrogenase (LDH) as well as 24 h values of nucleosomes were significantly higher in patients suffering from disease progression (N = 35) than in non-progressive patients (N = 14). Concerning overall survival, CEA, CA 19-9, CYFRA 21-1, CRP, LDH, AST, choline esterase (CHE), gamma-glutamyl-transferase, alkaline phosphatase, and amylase (all 0 h, 24 h) and nucleosomes (24 h) were found to be prognostic relevant markers in univariate analyses. In multivariate Cox-Regression analysis, the best prognostic model was obtained for the combination of CRP and AST. When 24 h values were additionally included, nucleosomes (24 h) further improved the existing model. Panels of biochemical markers are helpful to stratify pretherapeutically colorectal cancer patients for SIR-therapy and to early estimate the response to SIR-therapy

    Full Text Available The aim of the present study was to determine the effects of florfenicol on the expected changes in sTNF-α, damage markers of the liver and kidney, and the lipid metabolism parameters in endotoxemic brown trout. Ninety-six brown trout were included in this study. After six of the fish were reserved as the control group, the remaining 90 fish were divided equally into 3 groups as follows: LPS (2 mg/kg, IP, LPS (2 mg/kg, IP + florfenicol (40 mg/kg, IM, and florfenicol (40 mg/kg, IM. Blood samples were obtained from the tail of the fish at 1.5, 3, 6, 10, and 24 hours. The levels of sTNF-α were determined by ELISA and biochemical markers were evaluated with an autoanalyzer. A significant increase was observed in the values of sTNF-α in the LPS and LPS + florfenicol groups (P<0.05. Significant increases were found in the kidney and liver damage determinants in the LPS and LPS + florfenicol groups (P<0.05. Irregular changes in the lipid metabolism parameters were observed in all the subgroups. In conclusion, florfenicol does not affect the increases of sTNF-α caused by LPS and does not prevent liver or kidney damage; at least, it can be said that florfenicol does not have any evident positive effects on the acute endotoxemia of fish.

    To establish a safe anesthetic protocol with little effect on blood biochemical values and IV glucose tolerance test (IVGTT) results in Japanese black bears (Ursus thibetanus japonicus). 16 captive female Japanese black bears (5 to 17 years of age). Bears were randomly assigned to 4 treatment groups (4 bears/group) in which various treatment combinations were administered via blow dart: tiletamine HCl and zolazepam HCl (9 mg/kg) alone (TZ), TZ (6 mg/kg) and acepromazine maleate (0.1 mg/kg), TZ (6 mg/kg) and butorphanol tartrate (0.3 mg/kg), or TZ (3 mg/kg) and medetomidine HCl (40 μg/kg). Glucose injection for the IVGTT was started 130 minutes after TZ administration. Blood samples were obtained before, at, and intermittently after glucose injection for measurement of biochemical variables as well as plasma glucose and serum insulin concentrations during the IVGTT. Rectal temperature, pulse rate, and respiratory rate were assessed every 15 minutes during the experiment. Induction and maintenance of anesthesia were safely achieved with little adverse effect on cardiopulmonary function when each of the 4 anesthetic regimens was used, although mild hypothermia was induced. No difference was evident between treatment groups in blood biochemical values. Blood glucose and insulin concentration profiles during the IVGTT were similar among the bears given TZ, with or without acepromazine or butorphanol, but hyperglycemia and hypoinsulinemia developed in bears given TZ with medetomidine. All 4 anesthetic regimens yielded chemical restraint without affecting clinical and biochemical values in bears, but medetomidine appeared to affect IVGTT results. For this reason, medetomidine should not be used when anesthetizing bears for IVGTTs.

    Serum ferritin (SF) concentration as determined by the immunoradiometric method allows the direct measurement of a fraction of the body ferritin pool. In normal subjects, SF is an excellent index of body iron stores. In certain conditions associated with increased ferritin synthesis (such as liver disease, inflammation, malignancy, chronic disorders, ineffective erythropoiesis, or during ferrotherapy), SF may not accurately reflect body iron stores. In hyposideremic anemias SF concentration permits to differentiate those due to iron deficiency from those due to chronic disorders. With a good assay quality, subnormal SF levels are incontrovertible in the diagnosis of iron deficiency. SF determination has been investigated as possible tumor marker. When performed in combination with the alpha-fetoprotein assay, SF enhances the specificity of serodiagnosis of hepatoma. SF results must be interpreted bearing in mind the possible participation of circumstances that i) modify the body iron stores and ii) lead to increased ferritin synthesis. (author) [es

    imunoglobulinas e complementos.PURPOSE: the premature rupture of membranes (PROM has been a reason for many investigations, amongst which the involved immune mechanisms. Ahead of the scarcity of studies related to the subject, this work had as objective to evaluate the serum values of IgA, IgG, IgM, C3 and C4 in pregnant women with pre-term PROM. METHODS: in this transversal study, 36 pregnant women had been enclosed, with gestational age between 23 and 37 weeks. Of this total, 15 women had had laboratorial and clinical diagnosis of PROM. Patients with beginning of the childbirth work, clinical signals of infection, clinical dysfunction with systemic repercussion had been excluded. Serum concentrations of immunoglobulin (IgA, immunoglobulin M (IgM and immunoglobulin G (IgG, C3 and C4 had been evaluated in the patients with (study group and without PROM (control group. Correlation among dosages; number of childbirths and time of rupture was determined by Spearman coefficient correlation (r value. RESULTS: serum levels of IgA (average±SD had been significantly higher in the patients of the control group (271.0±107.0 versus 202.9±66.1; respectively, control and study group; p=0.024. There was no statistical difference when the levels of IgM, IgG, C3 and C4 had been compared between two groups. Significant association was not noticed between the number of childbirths and the IgA, IgM, IgG, C3 and C4 dosages (Spearman; r between -0,009 and 0,027; p>0,05. The average time of rupture of study group patients was of 19.1 hours (one - 72 hours, without association with the evaluated serum dosages. CONCLUSIONS: pregnant women with PROM show levels of IgA significantly lower than normal pregnant patients. The variable "number of childbirths" does not act as a factor of confusion in the comparative analysis of the dosages obtained in patients with or without PROM, as well as also it did not have association between the time of rupture and the immunoglobulin and complements serum dosages.

The combined use of two or more tumor markers (parallel test had a higher diagnostic sensitivity but lower specificity than a single tumor marker. The combined efficiency of HE4 and CA125 was the highest, with a sensitivity and specificity of 80.10% and 69.08%, respectively. HE4 and CA125 combined with the Risk of Ovarian Malignancy Algorithm provided an efficient means of screening and diagnosis of ovarian malignancies. The diagnostic sensitivity increased to 88.52% when three or four tumor markers were used but showed no significant difference compared with the combination of HE4 and CA125 (P>0.05. Conclusion: The combination of three or four tumor markers did not improve the diagnostic efficacy when compared with the combination

    Full Text Available This study examined protein adsorption equilibrium and kinetics on activated carbon (AC that we obtained from coal by single-step H3PO4 activation under N2+H2O vapor at 800 °C. Surface properties, pore size distribution, and volumes of AC were determined using the volumetric method with N2 adsorption at 77 K. Also, the textural properties were characterized by SEM-EDAX and XRD. The zeta potential values were measured to elucidate the electrostatic interactions between the protein and AC. The obtained AC discrete system was also used as an adsorbent for adsorbing bovine serum albumin (BSA from aqueous solution. The effects of pH (4.0, 5.0, and 7.4 and temperatures (20, 30 and 40 °C on the adsorption of BSA on AC were examined. The surface area, micropore, mesopore and total pore volumes of AC were found to be 1175 m2/g, 0.477 cm3/g, 0.061 cm3/g and 0.538 cm3/g, respectively. The optimum temperature for AC in BSA adsorption was found to be 40 °C and the pH was found to be 4.0. The highest BSA adsorption was found to be 159 mg/g and pH to be 4.0. The experimental equilibrium data were compared with the Langmuir and Freundlich models and found to be compatible with both models. The adsorption process is best described by the pseudo-first-order kinetic model. As a result, it was found out that AC obtained by single step H3PO4/N2+H2O vapor activation is an effective adsorbent for the adsorption of BSA from aqueous solution.

    3rd generation PTH assays only detect the bioactive 1-84 fragment. Since standardization is still lacking, each new PTH assay requires to establish reference values and to assess the impact in the medical care of the mineral and bone disorders in hemodialyzed patients. Using Fujirebio Lumipulse G wPTH assay, serum PTH levels were measured in a population of 439 healthy subjects from France and Belgium PTH levels were also determined in 119 hemodialyzed patients. These patients were classified according to the KDIGO recommendation. Reference range was found to be 6.5 (90%CI: 6.0-7.0) - 41.8 (90% CI: 38.1-43.7). In hemodialysis patients, Passing-Bablock regression between 3rd generation PTH from Fujirebio and DiaSorin was DiaSorin = 1.01 xFujirebio-2.4 with a slope not different from 1.0(95%CI: 0.96-1.04) and a non-significant intercept, ranging from -6.0 to 0.1. Hemodialysis patients with a PTH concentration below 2-fold the Upper Limit of Normality (ULN), within the KDIGO range and upper 9-fold upper limit were respectively 33.6%, 54.6%, 11.8% (Fujirebio Lumipulse) and 36.1%, 51.3% and 12.6% (Diasorin Liaison). We determined a reference range with the 3rd generation PTH assay from Fujirebio. In a hemodialysis population, 3rd generation assays from Fujirebio and DiaSorin provide similar results. To the best of our knowledge, this is the first time that we can show similar PTH results obtained by 2 different 3rd generation PTH assays in healthy subjects and hemodialyzed patients without mathematically processing them.

    Hepatic fatty infiltration appears as an area of increased echogenicity. And many factors concerned to fatty infiltration. With 65 cases of fatty liver and 42 cases of normal group, we analyzed fatty liver with grading and attempt to find relations between grade of fatty liver and levels of body index, serum triglyceride, and serum lipid. And compared fatty liver with normal control group. Patients with fatty liver are higher percentage of supra-normal value in body index, serum lipid, and serum triglyceride than normal control group. As fatty infiltration progressed, serum lipid, serum trig-lyceride and body index are also increased. Conclusively ultrasonographic examination of liver with serum triglyceride, serum lipid, and body index are simple method, useful follow-up examination of fatty liver, and preventive routine check-up of chronic liver disease

    Full Text Available Vertical infraclavicular brachial plexus block is utilized in patients with chronic renal failure at the time of creation of an arterio-venous fistula (AVF. The aim of this study is to test the effect of impaired renal function, with the resulting deranged serum electrolytes and blood gases, on the success rate and the onset of action of the local anesthetics used. In this prospective clinical study, we investigated the effect of the serum levels of sodium, potassium, urea, crea-tinine, pH, and bicarbonate on the onset of action of a mixture of lidocaine and bupivacaine administered to create infraclavicular brachial plexus block. A total of 31 patients were studied. The success rate of the block was 93.5 % (29 patients. The mean onset time for impaired or re-duced sensation was found to be 8.9 ± 4.7 mins and for complete loss of sensation, was 21.2 ± 6.7 mins. There was no significant association with serum sodium, potassium, urea, creatinine or the blood pH level (P> 0.05. The bivariate correlation between serum bicarbonate level and the partial and complete sensory loss was -0.714 and -0.433 respectively, with significant correlation (P= 0.00, 0.019. Our study suggests that infraclavicular block in patients with chronic renal failure carries a high success rate; the onset of the block is delayed in patients with low serum bicarbonate levels.

    Full Text Available PURPOSE: The present study was designed to determine the normal range of serum beta 2-microglobulin (Sb2M levels among healthy volunteers in Brazil. Levels of Sb2M are elevated in human immunodeficiency virus (HIV-infected patients and have been shown to be the best predictor of HIV infection status and of some malignant disorders, especially multiple myeloma. In order to achieve its optimal use in Brazilian clinical diagnosis, an adequate reference interval study was performed for Sb2M IMMULITE® assay, based on the fact that its reference range limits were evaluated among European populations. METHODS: Ninety-six healthy blood donors were evaluated, and Sb2M levels were measured by chemiluminescent enzyme immunoassay using the IMMULITE® automated analyzer. RESULTS: A normal range of Sb2M values, established by a nonparametric statistical method, was 1.05 to 3.9 mg/mL, with the upper limit being higher than that reported elsewhere. CONCLUSIONS: This study presented new data indicating that there is a significant difference between the current reference limits for Sb2M IMMULITE® assay and those found in Brazil, providing evidence that significant differences in range of normal values may occur among different populations, and that these new values should be considered for Brazilian individuals.OBJETIVO: O objetivo do presente estudo foi determinar valores de referência de beta2-Microglobulina sérica (Sb2M em voluntários saudáveis. Sabe-se que tal parâmetro apresenta-se elevado em pacientes infectados com o vírus da imunodeficiência humana (HIV e tem se mostrado melhor marcador da infecção por HIV e de desordens malignas, especialmente mieloma múltiplo. De forma a se obter o melhor diagnóstico clínico, um intervalo de referência adequado de Sb2M para a população brasileira foi determinado empregando-se o ensaio IMMULITE®; já que este tem como parâmetro uma faixa de referência determinada a partir de populações europ

    The measuremet of the serum level of squamous cell carcinoma-related antigen (SCC) purified from liver metastasis of cancer of the uterine cervix by an RIA kit is basically evaluated. The results of sensitivity, the recovery test, dilution test and variance test are good enough for clinical application. In gynecological disorders, the possitive rate is high (62 % [29/47]) in patients with cancer of the uterine cervix. Furthermore, the rate and level are related with the clinical staging. The changes of the serum SCC level in irradiated patients with cancer of the uterine cervix were a good reflection of the effectiveness of the treatment. (author)

    In a combined study 20 patients with diseases of liver parenchyma and/or of the bile duct system were investigated with SOLCO-SCINT-IODIDA and SOLCOSCINT-HEPATOBIDA. Patients with normal serum bilirubin do not show qualitative or quantitative differences in hepatobiliary function parameters. With increasing serum bilirubin (X = 15,4 ng/ml, range 3,9 to 42,6 ng/ml) a markedly increased diagnostic relevance could be shown up for IODIDA. Image contrast between liver and heart is better for IODIDA by a factor 2, and there was never seen any renal activity excretion in IODIDA-studies up to serum bilirubin of 40 mg/dl. In 2/3 of the studies IODIDA provided better clinical results, whereas in 1/3 of the cases both compounds did not show significant differences. In no case HIDA showed better results compared to IODIDA. IODIDA proves to be the radiopharmaceutical of choice for all hepatobiliary function studies. (orig.) [de

    Peel extracts from Citrus sinensis, Punica granatum, and Musa paradisiaca were investigated for their effects on tissue lipid peroxidation (LPO) and on the concentration of thyroid hormones, insulin, and glucose in male rats. In vitro inhibition of H(2)O(2)-induced LPO in red blood cells of rats by 0.25, 0.50, 1.0, and 2.0 microg/mL C. sinensis, P. granatum, and M. paradisiaca peel extracts was observed in a dose-specific manner. Maximum inhibition was observed at 0.50 microg/mL C. sinensis, 2.0 microg/mL P. granatum, and 1.0 microg/mL M. paradisiaca. In the in vivo investigation, out of four different concentrations of each peel extract, 25, 200, and 100 mg/kg C. sinensis, P. granatum, and M. paradisiaca, respectively, were found to maximally inhibit hepatic LPO. The most effective doses were further evaluated for effects on serum triiodothyronine (T(3)), thyroxine (T(4)), insulin, and glucose concentrations. C. sinensis exhibited antithyroidal, hypoglycemic, and insulin stimulatory activities, in addition to inhibition of LPO, as it significantly decreased the serum T(4) (P paradisiaca strongly inhibited the serum level of thyroid hormones (P < .01 for both T(3) and T(4)) but increased the level of glucose (P < .05). These findings reveal the hitherto unknown potential of the tested peel extracts in the regulation of thyroid function and glucose metabolism. Besides antiperoxidative activity, C. sinensis extract has antithyroidal, hypoglycemic, and insulin stimulatory properties, which suggest its potential to ameliorate both hyperthyroidism and diabetes mellitus.

    To know the interaction of amphiphilic drugs nortriptyline hydrochloride (NOT) and promazine hydrochloride (PMZ) with serum albumins (i.e., human serum albumin (HSA) and bovine serum albumin (BSA)), techniques of UV-visible, fluorescence, and circular dichroism (CD) spectroscopies are used. The binding affinity is more in case of PMZ with both the serum albumins. The quenching rate constant (k(q)) values suggest a static quenching process for all the drug-serum albumin interactions. The UV-visible results show that the change in protein conformation of PMZ-serum albumin interactions are more prominent as compared to NOT-serum albumin interactions. The CD results also explain the conformational changes in the serum albumins on binding with the drugs. The increment in %α-helical structure is slightly more for drug-BSA complexes as compared to drug-HSA complexes. Copyright © 2012 Elsevier B.V. All rights reserved.

    Having found raised serum calcitonin concentrations in 94% of patients with hepatocellular carcinoma when using a dextran-coated-charcoal radio-immunoassay, we have now repeated the study, using a double-antibody radio-immunoassay, in 102 further patients with hepatocellular carcinoma and 35 matched controls. Serum immunoreactive calcitonin concentrations (iCT) in the controls ranged from 10 to 310 pg/ml (mean 154,6 pg/ml). Values in the tumour patients ranged from 10 to 1,650 pg/ml (mean 302,6 pg/ml). The mean figures were significantly higher in the tumour patients (P smaller than 0,001), 35.5% of them having values above 310 pg/ml. In 65 of the patients serum iCT concentrations were also determined by dextran-coated-charcoal radio-immunoassay. Values ranged from 10 to 10780 pg/ml (mean 2,179 pg/ml). If 1,000 pg/ml is taken as the upper limit of normal, 69% of the patients had raised iCT concentrations. There was a good correlation (r=0,67; P smaller than 0,001) between serum iCT values measured with both methods in 50 patients. If measured by the double-antibody radio-immunoassay method, the serum calcitonin value is not useful as a marker for hepatocellular carcinoma.

    To investigate the relationship between the serum leptin and the children with malnutrition, the serum leptin levels in 50 malnourished children and 50 normal children were determined by RIA. The results showed that the serum leptin levels in children with malnutrition were significantly lower than that in control group (P<0.05). The serum leptin levels in children with malnutrition were positively correlated with body mass index values (r= 0.650, P<0.05), and positively correlated with serum albumin values (r= 0.740,P<0.05). The serum leptin levels in female children were higher than that in men children. The leptin may involve in the regulation of the body nutritional status of children. The serum leptin level may be correlated with the degree of child malnutrition and may be used as a laboratory indicator for the diagnosis of child malnutrition. (authors)

    Soluble corin was decreased in coronary heart disease. Given the connections between cardiac dysfunction and stroke, circulating corin might be a candidate marker of stroke risk. However, the association between circulating corin and stroke has not yet been studied in humans. Here, we aimed to examine the association in patients wtith stroke and community-based healthy controls. Four hundred eighty-one patients with ischemic stroke, 116 patients with hemorrhagic stroke, and 2498 healthy controls were studied. Serum soluble corin and some conventional risk factors of stroke were examined. Because circulating corin was reported to be varied between men and women, the association between serum soluble corin and stroke was evaluated in men and women, respectively. Patients with ischemic and hemorrhagic stroke had a significantly lower level of serum soluble corin than healthy controls in men and women (all P values, stroke than men in the highest quartile. Women in the lowest quartile of serum soluble corin were also more likely to have ischemic (OR, 3.10; 95% confidence interval, 1.76-5.44) and hemorrhagic (OR, 8.54; 95% confidence interval, 2.35-31.02) stroke than women in the highest quartile. ORs of ischemic and hemorrhagic stroke were significantly increased with the decreasing levels of serum soluble corin in men and women (all P values for trend, stroke compared with healthy controls. Our findings raise the possibility that serum soluble corin may have a pathogenic role in stroke. © 2015 American Heart Association, Inc.

    Full Text Available Background Organophosphate compounds cause poisoning and death more than any other insecticide. These toxins can cause peripheral neuropathy which is delayed for about 3 - 6 weeks and no method has been known for predicting the incidence. It has been claimed that electrophysiological tests (EMG - NCV can help in predicting the disorder. Objectives The main purpose of this research was to study EMG - NCV tests in patients with moderate to severe organophosphate poisoning. Methods This was a cross-sectional study conducted on patients with moderate to severe organophosphate poisoning from 2014 to 2016 in Imam Reza hospital of Mashhad. The minimum sample size was calculated as 68 patients and then all data was collected on the basis of inclusion and exclusion criteria using data collection form designed by the researcher, and finally data were analyzed using SPSS V.21 software, descriptive tests (including mean, median, mode and analytical tests (K square, ANOVA. Results Of all 78 patients with the mean age of 27.50 ± 10.0, 45 were female and the rest were male. Totally 29.5% of the patients had abnormal EMG - NCV. Although no significant differences were observed between electro diagnostic tests (EMG - NCV and age, gender, clinical symptoms and levels of acetylcholinesterase serum activity, the relationship between EMG - NCV and RBC levels of acetylcholinesterase activity was significant. Conclusions Electrophysiological tests are not associated with clinical symptoms (muscle weakness and they cannot be considered as a determining factor to discharge the patients; therefore, careful examination of the patients or evaluating the level of AChE activity in red blood cells is needed.

    Objective The influence of age on the performance of percent free prostate-specific antigen (%fPSA) in diagnosing prostate cancer (PCa) in East Asians is controversial. We tested the diagnostic performance of %fPSA in a multi-center biopsy cohort in China and identified the proper age-specific cutoff values to avoid unnecessary biopsies. Methods Consecutive patients with a prostate-specific antigen (PSA) level of 4.0–10.0 ng/ml or 10.1–20.0 ng/ml who underwent transrectal ultrasound-guided or transperineal prostate biopsy were enrolled from 22 Chinese medical centers from Jan 1, 2010 to Dec 31, 2013. The diagnostic accuracy of PSA and %fPSA was determined using the area under the receiver operating characteristic (ROC) curve (AUC). Age-specific cutoff values were calculated using ROC curve analysis. Results The median %fPSA was much lower in younger patients compared with older patients with a PSA level of 4.0–10.0 ng/ml or 10.1–20.0 ng/ml. The AUC of %fPSA was higher than PSA only in older patients. In patients aged 50 to 59 years, %fPSA failed to improve the diagnosis compared with PSA in these two PSA ranges. Age-specific cutoff values were 24%, 27% and 32% for patients aged 60–69, 70–79 and ≥80 years, respectively, to reduce unnecessary biopsies in men with PSA levels of 4.0–10.0 ng/ml to detect 90% of all PCa. Conclusions The effectiveness of %fPSA is correlated with age in the Chinese population. Age-specific cutoff values would help avoid unnecessary biopsies in the Chinese population. PMID:26091007

    Background: Hyperuricemia can cause serious health problems including renal insufficiency. Hyperuricemia is associated with many diseases including Hypertension, Diabetes Mellitus, Hypertriglyceridemia and Obesity. Objective of the present study was to study the Association of Serum Uric Acid with Blood Urea and Serum Creatinine. Methods: Eighty subjects, aged above 40, having blood urea more than 40 mg/dl and serum Creatinine more than 1.3 mg/dl were selected. 52.5 % subjects were male. Eighty subjects were selected as control group matching the age and sex with study group with normal blood urea and serum Creatinine. Results: Serum Uric Acid was found to be raised in 33 patients. Mean Serum Uric Acid value was 6.98+-2.021 in males (p<0.05) and 5.054+-2.324 in females (p<0.05). Conclusion: Serum Uric Acid is raised in patients with impaired renal function (p<0.05). Levels of increased Serum Uric Acid were not significantly associated with the cause of renal disease. (author)

    The zinc ion is essential for the living organism. Many pathological conditions have been described as a consequence of zinc deficiency. As zinc constitutes less than 0.01 percent of the body weight, it conventionally belongs to the group of trace elements. The method of atomic absorption spectrophotometry is used to measure the concentration of zinc in serum and urine from healthy persons. The assumptions of the method is discussed. The importance of protein binding, diet and the diurnal variation of serum zinc concentration is presented. Serum versus plasma zinc concentration is discussed. Reference serum zinc values from 104 normal subjects are given. Zinc in serum is almost entirely bound to proteins. A preliminary model for the estimation of the distribution of zinc between serum albumin and ..cap alpha../sub 2/-macroglobulin is set up. This estimate has been examined by an ultracentrufugation method. The binding of zinc to a ..cap alpha../sup 2/-macroglobulin in normal persons is appoximately 7 percent, in patients with cirrhosis of the liver of alcoholic origin approximately 6 percent, in patients with insulin dependent diabetes mellitus approximately 5 percent, and in patients with chronic renal failure approximately 2 percent. It is concluded, therefore, that for clinical purposes it is sufficient to use the concentration of total serum zinc corrected for the concentration of serum albumin.

    Measurements of the serum Vitamin B 12 concentrations of 49 black and 49 white healthy adults demonstrate a significantly higher mean serum Vitamin B 12 level in blacks when compared to whites. The reason for this difference appears to be genetic, although environmental factors may also be involved. It is suggested that clinical laboratories should establish their own separate reference values of serum Vitamin B 12 for blacks and whites in order to prevent misinterpretation of test results

    Erythropoietin (Epo) is the first well studied hemopoietic growth factor. The pathological levels of its serum concentration show deviations in the specific mechanisms for some diseases such as polycythemia. Objective of this work is the assessment of the diagnostic value of the Epo in the serum for the differentiation of the main form of polycythemia - true and symptomatic. Material and methods: 47 patients are studied (21 women and 26 men), 23 of them are with polycythemia vera and 24 with polycythemia symptomatica. The following has been determined: the serum level of Erythropoietin, hemoglobin, the number of erythrocytes, leukocytes, thrombocytes, myelogram. The serum level of Epo is quantitatively determined b using of radioimmunological method, through Epo-Trac kit. Results: The diagnosis is also confirmed in all patients by other laboratory tests. The normal values of Epo in healthy persons are 17.0±7.0 mU/ml. The average Epo level in patients with polycythemia vera is 20.4±3.0 mU/ml. In one patient the Epo level is supposedly connected with an accompanying kidney disease. Conclusions: The obtained data show that the Epo serum level is an accurate criterion in the diagnosing of true and symptomatic polycythemia. The true polycythemia is connected with an independent erythrocyte production. In the symptomatic polycythemia the tissue hypoxia stimulated the Epo production

    A National Serum Bank was established to store sera obtained during the National Seroepidemiological Survey performed in Mexico in 1987. More than 70,000 serum samples were obtained from subjects of either sex 1-99 years of age in each of the 32 states of the country. The current collection of sera includes 28,704 male samples and 40,629 female samples. This paper describes the procedures for handling serum samples, including reception registry, storage and distribution to several laboratories for detection of measles, rubella, poliomyelitis, AIDS, diphtheria, pertussis, tetanus, brucella, salmonella, amoeba, toxoplasma, American trypanosomiasis and cysticercus. Determinations of total cholesterol were also made in order to describe its distribution and to identify the prevalence of hypercholesterolemia.

    Use of hormone contraceptives (HC) is very popular in the reproductive age and, therefore, evaluation of ovarian reserve would be a useful tool to accurately evaluate the reproductive potential in HC users. We conducted a retrospective cohort study of 41 HC users compared to 57 non-HC users undergoing IVF-preimplantation genetic diagnosis (PGD) aiming to evaluate the effect of HC on the levels of anti-Mullerian hormone (AMH), small (2-5 mm), large (6-10 mm) and total antral follicle count (AFC) and the ability of these markers to predict IVF outcome. Significant differences in large AFC (p = 0.04) and ovarian volume (p users (p users these correlations were weaker. In HC users, the significant predictors of achieving 18 oocytes were AFC (ROC-AUC; 0.958, p = 0.001 and 0.883, p = 0.001) and AMH (ROC-AUC-0.858, p = 0.01 and 0.878, p = 0.001), respectively. The predictive values were less significant in non-HC users. These findings are important in women treated for PGD, in ovum donors and for assessing the fertility prognosis in women using HC and wishing to postpone pregnancy.

    1981-01-01

    The thyroid function at various stages of pregnancy and after delivery was assessed by measuring serum total triiodothyronine (T 3 ), T 3 resin uptake (T 3 RU) and free triiodothyronine index (FT 3 I). In first, second and third trimesters of pregnancy, the mean values of serum total T 3 were significantly elevated (P 3 I remained unaltered. During labour, both serum total T 3 and FT 3 I observed during labour and after delivery may be due to the changes in blood oestrogen levels. This study indicates that serum free T 3 concentrations in pregnancy remained unaltered in the presence of elevated serum total T 3 levels. FT 3 I determination would thus appear to be a reliable in vitro thyroid function test for the assessment of thyroid function throughout pregnancy. Serum total T 3 was measured by radioimmunoassay using radioiodinated T 3 ( 125 I-T 3 ). (author)

    2015-01-01

    Full Text Available Introduction: Olanzapine is a commonly used antipsychotic. Prolactin elevation is a common adverse effect of anstipsychotics, and serum prolactin elevation is seen in about 30% patients treated with olanzapine. There are confounding results about dose dependency of olanzapine and prolactin elevation, and also the duration of treatment. Method: Fifty six patients, 36 male and 20 female, who were taking olanzapine for any condition for more than a month at a constant dose were enrolled in the study. Patients’ age, weight, body mass index (BMI, serum prolactin levels, and some biochemical values were recorded. Patients were taken from the review outpatient department (OPD after due consent. Results: Five each in male and female groups showed elevation of serum prolactin (estimated to be high if >20 ng/dl for males, and >25 ng/dl for females. In females, the elevation was found at lesser dose of olanzapine (13 mg/day, in males 18 mg/day and early in the treatment (2.4 months vs. 9.7 months in males. Males tended to show raised prolactin with higher doses of olanzapine (mean 18 mg/day. Females (26.31% also showed higher prevalence of prolactin elevation compared to males (13.51%. No other parameter was found to modify the prolactin levels. Conclusion: Olanzapine causes elevation of serum prolactin, though lesser degree than some other antipsychotics. Females are more prone to have raised serum prolactin with olanzapine compared to males. However, the elevation seems to be transient. Higher doses of olanzapine tend to cause elevation of serum prolactin. Serum prolactin estimation in patients taking olanzapine may be undertaken to maintain quality life, particularly in females.

    The liver plays a fundamental role in iron homeostasis. Iron parameters change, especially ferritin, need to be evaluated in patients with liver cirrhosis. Serum ferritin could predict the prognosis of patients with decompensated cirrhosis since it reflects immunemediated and infectious stimuli. Ferritin could express the severity of liver disease and possible subsequent complications. Finally, it might reflect an iron overload condition resulting in significant morbidity and early mortality. 70 patients with decompensated liver cirrhosis divided into three Child-Pugh subgroups. Serum iron parameters include serum iron (SI), total iron binding capacity (TIBC) and ferritin was measured in these groups. From these 70 patients, 30 (42.9%) with HbsAg positive, 26 (37.1%) with anti-HCV positive and 14 (20%) with both HbsAg and anti-HCV positive. Of the 70 patients, 14 (20%) had CTP Class A cirrhosis, 17 (24.3%) had CTP Class B cirrhosis, and 39 (55.7%) had CTP C cirrhosis. The median (range) value of serum iron was 36 (10-345) μg/dl, TIBC was 160 (59-520) μg/dl, Ferritin was 253.5 (8-6078) ng/ml and the transferrin saturation was 22.9 (3.65-216.98) %.We found a significant difference in serum ferritin level with CTP score. Ferritin levels increased as Child-Pugh class progressed (p<0.001).

    1982-01-01

    We propose a double antibody radioimmunoassay for human prostatic acid phosphatase (PAP) in serum for diagnosis and management of prostatic adenocarcinoma under treatment. The antigen is purified from human prostatic fluid by a gel-filtration on Sephadex G 100 followed by affinity chromatography on Con A Sepharose. A specific antibody is raised in rabbits and purified by immunoadsorption with a female serum. The described technique offers both radioisotopic sensibility and immunologic specificity. Physiological values determined in the serum of 125 healthy males are below 2 ng/ml. No significative differences are observed with age. The proposed technique also shows significant differences between values evaluated for benign prostatic hyperplasia and prostatic adenocarcinoma.

    Three groups of male rats were housed in metabolic cages. The control group was fed ad libitum, a second group was fasted and diabetes was induced in the third group by the subcutaneous injection of alloxan. After 48 hours all animals were bled and livers, which were quick-frozen in situ, were obtained. Fasted and diabetic animals were ketotic as manifested by lowering urinary pH and elevated urinary and blood acetoacetate and ..beta..-hydroxybutyrate. Blood and hepatic content of acetate was elevated in diabetic versus control rats. Blood and hepatic content of acetate was not increased in fasted animals. In fasted rats total urinary Zn and Cu were decreased and Mg and Ca did not differ significantly from control values. In diabetic rats total urinary excretion of Mg was increased whereas urinary Zn, Cu and Ca levels did not differ significantly from control values. In fasted animals only serum Zn was diminished. In diabetic rats serum Cu and Ca were decreased and serum Mg was increased while serum Zn was unchanged. Thus, the ketosis of fasting differs from the ketosis of diabetes in several of its metabolic manifestations. 11 references, 9 figures.

    Mild acute pancreatitis (MAP) is a common acute abdominal disease, and exhibits rising incidence in recent decades. As an important component of systemic biology, metabonomics is a new discipline developed following genomics and proteomics. In this study, the objective was to analyze the serum metabonomics of patients with MAP, aiming to screen metabolic markers with potential diagnostic values. An analysis platform with ultra performance liquid chromatography-high-resolution mass spectrometry was used to screen the difference metabolites related to MAP diagnosis and disease course monitoring. A total of 432 endogenous metabolites were screened out from 122 serum samples, and 49 difference metabolites were verified, among which 12 difference metabolites were identified by nonparametric test. After material identification, eight metabolites exhibited reliable results, and their levels in MAP serum were higher than those in healthy serum. Four metabolites exhibited gradual downward trend with treatment process going on, and the differences were statistically significant (P Metabonomic analysis has revealed eight metabolites with potential diagnostic values toward MAP, among which four metabolites can be used to monitor the disease course. © 2016 Wiley Periodicals, Inc.

    Continuing improvements in analytical technology along with an increased interest in performing comprehensive, quantitative metabolic profiling, is leading to increased interest pressures within the metabolomics community to develop centralized metabolite reference resources for certain clinically important biofluids, such as cerebrospinal fluid, urine and blood. As part of an ongoing effort to systematically characterize the human metabolome through the Human Metabolome Project, we have undertaken the task of characterizing the human serum metabolome. In doing so, we have combined targeted and non-targeted NMR, GC-MS and LC-MS methods with computer-aided literature mining to identify and quantify a comprehensive, if not absolutely complete, set of metabolites commonly detected and quantified (with today's technology) in the human serum metabolome. Our use of multiple metabolomics platforms and technologies allowed us to substantially enhance the level of metabolome coverage while critically assessing the relative strengths and weaknesses of these platforms or technologies. Tables containing the complete set of 4229 confirmed and highly probable human serum compounds, their concentrations, related literature references and links to their known disease associations are freely available at http://www.serummetabolome.ca.

    We investigated the interactions between dendrimer-coated magnetite nanoparticles (MNPs) and the protein serum albumin. The investigation was based on the fluorescence quenching of tryptophan residue of serum albumin after binding with the dendrimer-coated magnetite nanoparticles. The extent of the interactions between bovine serum albumin and dendrimer-coated MNPs strongly depends on their surface groups and pH value

    Two direct radioimmunoassays for progesterone in 50 μL of unextracted serum or plasma with assays involving extraction of serum were compared. The direct assays include the use of either danazol at pH 7.4 or 8-anilino-1-naphthalenesulfonic acid at pH 4.0 to displace progesterone from serum binding-proteins. Progesterone is then assayed by using an antiserum to a progesterone 11α-hemisuccinyl conjugate and the radioligand 125 I-labeled progesterone 11α-glucuronyl tyramine, with separation by double-antibody techniques. Direct assays with either displacing agent gave good analytical recovery of progesterone added to human serum, and progesterone values for patients' specimens correlated well (r > 0.96) with results of assays involving extraction of serum. Precision was similar with each displacing agent over the working range 2.5-100 nmol/L and superior to that of extraction assays. We conclude that these direct assays of progesterone are analytically valid and more robust, precise, and technically convenient than many conventional methods involving extraction of serum

    To determine the serum hyaluronic acid (HA) levels as biochemical marker of hepatic fibrosis and cirrhosis and correlate it with the degree of hepatic fibrosis and cirrhosis. This study was performed on 100 patients of chronic liver disease whose liver biopsies had been carried out. Fifty healthy controls were also included in the study. Routine liver function tests, hepatitis serology and serum hyaluronic acid levels were carried out on patients and controls. Liver biopsy of 100 patients revealed that 21 were in stage 0 fibrosis, 38 in stage 1 fibrosis, 26 in stage 3 fibrosis and 15 in stage 4 fibrosis. Mean Serum HA (mean +- SD) concentration in patients were 189 +- 98 mg/L vs. 21 +- 10 mg/L of healthy controls. The difference observed was statistically significant (p < 0.001). Patients in stage 4 fibrosis had significantly higher (p <0.001) mean serum HA concentration as compared to other stages of liver fibrosis. Diagnostic accuracy of serum HA at marginally elevated level of 60 mg/L determined the sensitivity 78.4 %, specificity 80.9%, positive predicted value 93.9% and negative predicted value of 50%. Serum HA is a useful non-invasive marker of liver fibrosis. There is a strong positive correlation between serum HA levels and degree of liver fibrosis. The concentration of serum HA rises according to progression of liver fibrosis and levels are highest in patients with liver cirrhosis. (author)

    Full Text Available Background Hemolysis and repeated blood transfusions in children with thalassemia major cause iron overload in various organs, including the brain, and may lead to neurodegeneration. Hemolysis also causes decreased levels of nitric oxide, which serves as a volume transmitter and slow dynamic modulation, leading to cognitive impairment. Objective To assess for correlations between serum ferritin as well as nitric oxide levels and cognitive function in children with thalassemia major.  Methods This analytical study with cross-sectional design on 40 hemosiderotic thalassemia major patients aged 6−14 years, was done at the Thalassemia Clinic in Dr. Hasan Sadikin Hospital, Bandung, West Java, from May to June 2015. Serum ferritin measurements were performed by an electrochemiluminescence immunoassay; serum nitric oxide was assayed by a colorimetric procedure based on Griess reaction; and cognitive function was assessed by the Wechsler Intelligence Scale for Children test. Statistical analysis was done using Spearman’s Rank correlation, with a significance value of 0.05. Results Abnormal values in verbal, performance, and full scale IQ were found in 35%, 57.5% and 57.5%, respectively. Serum nitric oxide level was significantly correlated with performance IQ (P=0.022, but not with verbal IQ (P=0.359 or full scale IQ (P=0.164. There were also no significant correlations between serum ferritin level and full scale, verbal, or performance IQ (P=0.377, 0.460, and 0.822, respectively. Conclusion Lower serum nitric oxide level is significantly correlated to lower cognitive function, specifically in the performance IQ category. However, serum ferritin level has no clear correlation with cognitive function.

    Measuring serum creatinine is cheap and commonly done in daily practice. However, interpretation of serum creatinine results is not always easy. In this review, we will briefly remind the physiological limitations of serum creatinine due notably to its tubular secretion and the influence of muscular mass or protein intake on its concentration. We mainly focus on the analytical limitations of serum creatinine, insisting on important concept such as reference intervals, standardization (and IDMS traceability), analytical interferences, analytical coefficient of variation (CV), biological CV and critical difference. Because the relationship between serum creatinine and glomerular filtration rate is hyperbolic, all these CVs will impact not only the precision of serum creatinine but still more the precision of different creatinine-based equations, especially in low or normal-low creatinine levels (or high or normal-high glomerular filtration rate range). © 2017 S.

    With blood obtained from patients irradiated for cervical uterine cancer (consisting of 4 cases of Stage I, 5 cases of Stage II and 4 cases of Stage III), changes of blood picture, serum lipid weight and serum lipid peroxide accompanying irradiation were studied on 3 occasions, before, during and after the irradiation. The following results were obtained. Serum lipid and serum lipid peroxide were found to increase along with the advance of uterine cancer from Stage I to II and III. At the termination of irradiation the serum lipid and serum lipid peroxide in the cases of cervical uterine cancer at Stage III were found to have recovered to close to the levels before irradiation, but in the other cases these values tended to increase with irradiation. Except the termination of irradiation treatment of cervical uterine cancer of Stage III, the decrease of leucocyte count has a mutual relationship with the increase of serum thiobarbituric acid (TBA), so that change in the serum TBA level can be assumed to be a criterion for irradiation injury.

    Full Text Available Transforming growth factor-beta1 (TGF-β1, a multi-functional cytokine, is involved in regulating a variety of cellular activities and the serum/plasma TGF-β1 level is altered with various diseases. However, most published reports have described adult patients, and so we investigated the clinical significance of serum TGF-β1 level in pediatric patients. The diagnostic application of the measurement of serum TGF-β1 level depends critically on the control value, however, there is no information on the control value of serum TGF-β1 for children.

  8. Default values

    International Nuclear Information System (INIS)

    1987-08-01

    In making calculations for the purposes of radiation protection, numerical values for parameters used in the calculations are selected. In some cases, data directly applicable to the set of conditions for which the calculations are to be made are unavailable. Therefore, the selection of the values for these parameters may be based on more general data available from the literature or other sources. These values may be referred to as 'default values', that is, values used in default of those based on directly applicable data. The following policy will be applied by Atomic Energy Control Board (AECB) staff in reviewing the radiation protection aspects of submissions associated with licensing, in participating with other organizations in the development of codes and standards, and in any other work which relies to some extent on using default values

    A radioimmunological method for the measurement of 17-OH-P in serum is described. An anti-serum with high titer, high coefficient of affinity and good especificity was produced in rabbits using a 17-OH-P derivative coupled to bovine serum albumin through the 3 position. Three preparative methods were studied. Two of them were chromatographic methods (Sephadex LH-20 and Celite) and showed equivalent results; the third method, using simple ether extraction gave higher values. Because of its easy and quick execution, the LH-20 method was chosen for the rest of the study. The method is highly sensitive and accurate enough for clinical use. The values obtained in normal women in the folicular and luteal fases and the values found in patients with 21-hydroxilase defect where comparable to the values found in the literature. (Author) [pt

    Serum levels of cholylglycines (CG) were determined by radioimmunoassay and that of total bile acids (TBA) by enzymatic method. In normal subjects, serum levels of CG, TBA and CG/TBA ratio were 0.6 +- 0.4 μM, 7 +- 2 μM, and 0.08 +- 0.06, respectively. They were increased markedly in acute hepatitis and moderately in chronic hepatitis and cirrhosis. Thus, measurement of serum CG as compared with serum TBA appears to be a sensitive liver test.

    The aim of this clinical study was to determine whether there is a relationship between total serum testosterone, free testosterone, FSH (Follicle-Stimulating Hormone), LH (Luteinizing Hormone) and serum prostate specific antigen (PSA) levels. We postulated that such a correlation existed then the use of hormone specific reference ranges might enhance the usefullness of PSA concentrations 40 years of age visiting our urology outpatient clinics. PSA was correlated to age (r = 0.23, p = 0.019), but there none between serum testosterone and age. No significant correlation was noted between testosterone or free testosterone and serum PSA levels, and none between serum FSH or LH and PSA. In age specific reference groups (41-49; 50-59; 60-69 years), we found no significant correlation between PSA and hormone concentrations. In this population of eugonadal men with serum PSA values less than 2.5 ng/ml, serum androgens and pituitary hormones do not appear to correlate with serum PSA.

    An inadequate and imbalanced intake of protein and energy results in protein-energy malnutrition (PEM). It is known that bone mineral density and serum magnesium levels are low in malnourished children. However, the roles of serum magnesium and endothelin-1 (ET-1) levels in the pathophysiology of bone mineralization are obscure. Thus, the relationships between serum magnesium and ET-1 levels and the changes in bone mineral density were investigated in this study. There was a total of 32 subjects, 25 of them had PEM and seven were controls. While mean serum ET-1 levels of the children with kwashiorkor and marasmus showed no statistically significant difference, mean serum ET-1 levels of both groups were significantly higher than that of the control group. Serum magnesium levels were lower than normal value in 9 (36%) of 25 malnourished children. Malnourished children included in this study were divided into two subgroups according to their serum magnesium levels. While mean serum ET-1 levels in the group with low magnesium levels were significantly higher than that of the group with normal magnesium levels (p malnutrition. Our study suggested that lower magnesium levels and higher ET-1 levels might be important factors in changes of bone mineral density in malnutrition. We recommend that the malnourished patients, especially with hypomagnesaemia, should be treated with magnesium early.

    1977-01-01

    A sensitive radioimmunoassay for measurements of 3,3,5-triiodothyronine (reverse T3,rT3) in small amounts of unextracted serum is described. The interference of rT3 binding proteins in serum was precluded by addition of 8-anilinol-naphthalene sulphonic acid (ANS). The cross reaction of T4 with the rT3 anti-serum varied with the concentration of T4 in the samples. At 50 per cent inhibition of I 125 rT3 binding, the T4 cross reaction was 0.075% (mol/mol). All values were corrected for T4 cross reaction. By the present method total rT3 averaged 0.37 nmol/l in thirty-two normal subjects. Higher values (0.81-1.98 nmol/l) were obtained in seventeen thyrotoxic patients, while the rT3 was very low (<=0.046 nmol/l) in ten patients with severe primary hypothyroidism. A modification of the total rT3 assay was used for measurements of rT3 in serum dialysates (free rT3). The sensitivity was 0.46 pmol/l. This sensitivity did not allow detection of free rT3 in all normal subjects. (Auth.)

    Chaojun Qi

    Full Text Available Lupus nephritis (LN is among the most serious complications of systemic lupus erythematosus (SLE, which causes significant morbidity and mortality. Renalase is a novel, kidney-secreted cytokine-like protein that promotes cell survival. Here, we aimed to investigate the relationship of serum renalase levels with LN and its role in the disease progression of LN.For this cross-sectional study, 67 LN patients and 35 healthy controls were enrolled. Seventeen active LN patients who received standard therapies were followed up for six months. Disease activity was determined by the SLE Disease Activity-2000 (SLEDAI-2K scoring system and serum renalase amounts were determined by ELISA. Predictive value of renalase for disease activity was assessed. Furthermore, the expression of renalase in the kidneys of patients and macrophage infiltration was assessed by immunohistochemistry.Serum renalase amounts were significantly higher in LN patients than in healthy controls. Moreover, patients with proliferative LN had more elevated serum renalase levels than Class V LN patients. In proliferative LN patients, serum renalase levels were significantly higher in patients with active LN than those with inactive LN. Serum renalase levels were positively correlated with SLEDAI-2K, 24-h urine protein excretion, ds-DNA and ESR but inversely correlated with serum albumin and C3. Renalase amounts decreased significantly after six-months of standard therapy. The performance of renalase as a marker for diagnosis of active LN was 0.906 with a cutoff value of 66.67 μg/ml. We also observed that the amount of renalase was significantly higher in glomerular of proliferative LN along with the co-expression of macrophages.Serum renalase levels were correlated with disease activity in LN. Serum renalase might serve as a potential indicator for disease activity in LN. The marked increase of glomerular renalase and its association with macrophages suggest that it might play an

    2012-01-01

    Objective: To determine whether serum vitamin D levels are correlated with serum levels of alkaline phosphatase or not. Study Design: Cross-sectional, observational study. Place and Duration of Study: Multi-centre study, conducted at Liaquat National Hospital and Medical College, National Medical Centre and Medicare Hospital, Karachi, from January to October 2009. Methodology: Patients attending the Orthopaedic OPDs with complaints of pain in different body regions and serum vitamin D/sub 3/ levels of greater or equal to 30 ng/ml were included in the study. Patients with vitamin D deficiency were further categorized into mild deficiency or insufficiency (vit. D/sub 3/ = 20-29 ng/ml), moderate deficiency (vit. D/sub 3/ = 5 - 19 ng/ml) and severe deficiency forms (vit. D/sub 3/ < 5 ng/ml). Pearson correlation was applied to test the correlation of serum alkaline phosphatase levels with serum vitamin D/sub 3/ levels. P-value < 0.05 was considered to be significant. Results: Out of 110 samples, 26 had mild (23%), 61 had moderate (55%) and 21 had severe (19.1%) vitamin D deficiencies. All of the patients in the three groups had alkaline phosphatase with in normal limits and the total mean value of the enzyme was 135.97 +- 68.14I U/L. The inter group comparison showed highest values of alkaline phosphatase in the moderate vitamin D deficiency group. The correlation coefficient of alkaline phosphatase and serum vitamin D/sub 3/ levels was r =0.05 (p =0.593). Conclusion: Serum vitamin D/sub 3/ levels may not be correlated with increased serum alkaline phosphatase levels. Therefore, alkaline phosphatase may not be used as a screening test to rule out vitamin D deficiency. (author)

    age: 2 years and 2 months and Group II with 30 children (median age: 3 years and 6 months. Their food intake, weight, height and serum hemoglobin levels were measured at the beginning and at the end of the study. During a period of two months, milk and bread, which made up the children's breakfast and afternoon snack, were substituted by the enriched cereal in the form of porridge, which increased the iron intake in 2 to 3mg per day. The results showed that there was a significant increase in the weight for height rate of both groups, with improvement of nutritional condition in those children with acute malnutrition. With regard to serum hemoglobin levels, Group I showed an initial average level of 9.9 ± 2.0g/dl. The average level at the final evaluation, 11.4 ± 1.0g/dl, was significantly higher (p< 0.05 than at the start. Group II, with average serum hemoglobin level of 11.6 ± 0.9g/dl at the start, did not show a significant difference from the level at the end (11.9± 0.9g/dl.At the start of the study the incidence of anemia in Group I was of 81%. This value went down to 31.2% at the end of two months. For Group II, the incidence decreased from 20.8% to 12.5% at the end. The average daily intake of cereal during the first week was lower than in subsequent weeks. It is concluded that the product used in this study increased the serum hemoglobin levels of the children with anemia and contributed to the nutritional improvement of those who were malnourished. In addition, the cereal was well accepted by the children.

    Patterns of serum biochemical parameters vary among horse breeds. The objective of the present study was to compare serum lipoproteins of Iranian Caspian ponies with those of other horses (Arabs and Thoroughbreds) in the Iranian region. Serum lipoprotein values were determined by agar-agarose gel electrophoresis and measured by scan densitometry. Moreover, serum triglyceride and cholesterol concentrations were determined and the results were analysed by one-way analysis of variance. Serum triglyceride and cholesterol values were 1.13 +/- 0.23 and 2.38 +/- 0.18 mmol/l in Caspian ponies, 1.96 +/- 0.49 and 1.92 +/- 0.25 mmol/l in Arab horses and 1.38 +/- 0.26 and 2.17 +/- 0.53 mmol/l in Thoroughbred horses. The relative percentages of alpha- (72.63 +/- 17.76%) and beta-lipoproteins (29.10 +/- 5.49%) in serum electrophoretic tracings from Caspian ponies were not significantly different from those of other horses (p > 0.05). The lipoprotein phenotype in Caspian ponies may be useful for evaluating metabolic diseases.

    Multiple free-radical scavenging (MULTIS) activity in cattle and human sera was evaluated with electron spin resonance spectroscopy. Scavenging rates against six active species, namely hydroxyl radical, superoxide anion, alkoxyl radical, alkylperoxyl radical, methyl radical, and singlet oxygen were quantified. The difference in the electron spin resonance signal intensity in the presence and absence of the serum was converted into the scavenging rates. Comparative MULTIS measurements were made in sera from eight beef cattle, three fetal calves and fifteen healthy human volunteers. Further, we determined the MULTIS value of albumin, the most abundant component in serum. MULTIS values in cattle sera indicated higher scavenging activity against most free radical species tested than human sera. In particular, cattle serum scavenging activities against superoxide and methyl radical were higher than human serum by 2.6 and 3.7 fold, respectively. In cattle serum, albumin appears to play a dominant role in MULTIS activity, but in human serum that is not the case. Previous data indicated that the abundance of uric acid in bovine blood is nearly 80% less than humans; however, this difference does not explain the deviation in MULTIS profile.

    Objective To study the diagnostic value of serum procalcitonin (PCT) in patients with liver cirrho-sis complicated with hepatorenal syndrome. Methods A total of 106 patients with liver cirrhosis were selected from January 2010 to January 2015 in our hospital, which were divided into two groups according to whether the patients were complicated with hepatorenal syndrome:32 cases with hepatorenal syndrome (group A) and 74 cases without hepa-torenal syndrome (group B). Another 40 subjects with good health were selected as the control group. The serum PCT lev-els, total bile acid (TBA), Cystatin C (Cys C), C-reactive protein (CRP), and white blood cell count (WBC) of three groups were tested and compared, and the 24 h creatinine clearance rate (Ccr) of three groups was calculated. The correlation between biochemical indexes and serum PCT was analyzed. Results The PCT ((4.02±1.20)μg/L vs (0.33±0.02)μg/L vs (0.13±0.03)μg/L), WBC ((6.03±1.03)×109/L vs (3.94±1.82)×109/L vs (5.51±1.29)×109/L), CRP ((6.24±1.92) g/L vs (5.73 ± 1.24) g/L vs (1.60 ± 0.39) g/L), Cys-C ((2.34 ± 0.32) mg/L vs (0.79 ± 0.11) mg/L vs (0.67 ± 0.20) mg/L), TBA ((33.29±3.94)μmol/L vs (23.39±3.04)μmol/L vs (20.39±2.02)μmol/L) were significantly higher in group A than group B and the control group (P<0.05). The 24 h Ccr level was significantly lower than in group A than group B and the con-trol group ((62.48±6.02) mL/min vs (83.13±8.22) mL/min vs (90.38±8.34) mL/min), P<0.05. PCT was negatively corre-lated with 24 h Ccr (rgroup B=-0.278, rgroup A=-0.600), positively correlated with the level of CRP (rgroup B=0.244, rgroup A=0.605), and positively correlated with Cys-C (rgroup B=0.247, rgroup A=0.530). Conclusion The possibility of patients with cirrhosis suffering from hepatorenal syndrome is higher for patients with increased PCT level. Serum PCT has a high value in the diagnosis of liver cirrhosis complicated with hepatorenal syndrome.%目的:探讨肝硬化合并肝肾综

    Full Text Available Background: Seizure is a common neurological disorder in neonatal age group!. Primary metabolic derangement is one of the important reason behind this convulsion during this period. Among primary metabolic derangement hypoglycemia, is most common followed by bypocalcaemia, hypomagnesaemia, low zinc status etc. As causes of many cases of convul­sion remain unknown in neonate. Objectives: To see the zinc status in the sera of neonate with convulsion. So that if needed early intervention can be taken up and thereby prevent complications. Method: A total of 50 neonates (1-28 days who had convulsion with no apparent reasons of convulsion were enrolled as cases and 50 healthy age and sex matched neonates were enrolled as controls. After a quick clinical evaluation serum zinc status was estimated from venous blood by atomic absorption method in Chemistry Division, Atomic Energy Centre. Low zinc was considered if serum value was <0.7mg/L. Results: Among a total of 50 cases 6% had low zinc value & 2% of controls also had low zinc level. The mean serwu zinc level of cases and controls were 1.57±0.95 and 2.37±1.06 mmol/1 respectively (p<0.01. Conclusion: From the study it is seen that low zinc value is an important cause of neonatal seizure due to primary metabolic abnormalities. So early recognition and treatment could save these babies from long term neurological sequelies.

    Full Text Available Preeclampsia remains a health problem that becomes one of the causes of maternal deaths besides bleeding and infection. The etiology and pathogenesis of preeclampsia are unclear. Increased serum uric acid levels is seen simultaneously with the increase of blood pressure and occurred before the onset of proteinuria. Therefore, the uric acid can be used as a biomarker. The aim of this study was to analyze the serum uric acid levels between normal and preeclampsia pregnancies. The study was conducted in Dr.Hasan Sadikin Hospital Bandung between March and May 2011, using cross sectional study design. Subjects were 45 inpartu normal pregnant women as control and 44 in partu pregnant women with preeclampsia accordance with inclusion and exclusion criteria. Levels of uric acid in normal pregnancy are 3,43 ±0.14 mg/dL. In this study uric acid levels resulting in cut-off levels of 4,8 mg/dL with a sensitivity value of 93%, and specificity 80%. Conclusions: uric acid levels in at term preeclampsia are higher compared with normal pregnancies. Increased levels of uric acid can be considered as one of biomarkers of preeclampsia, hence the serum uric acid levels used as serial examinations in pregnant women during antenatal care.

    We show how zinc may easily be quantified in serum by first using an optimum concentration of guanidine hydrochloride to cause release of zinc from proteins, followed by complexation of released metals with cyanide. The cyanide complex of zinc is preferentially demasked with chloral hydrate, followed by a colorimetric reaction between zinc and 4-(2-pyridylazo)resorcinol. This is a sensitive water-soluble ligand; its complex with zinc has an absorption maximum at 497 nm. Values found by this technique compare favorably with those obtained by atomic absorption spectroscopy.

    In patients with histologically ascertained bronchial carcinoma the tumor volume and the plasma volume was determined before therapy. Following the first irradiation of the tumor with a /sup 60/Co pendulum technique over the diseased side with 5 Gy for the 80% isodose determination of aldolase and creatin kinase was performed frequently during 24 h. A peak of serum aldolase was found 16 - 18 h after irradiation. The aldolase values of this peak were higher for undifferentiated carcinomas than for squamous cell carcinomas and proportional to the size of the tumor. The hypothesis is made that by means of this method using different radiation qualities their 'relative biological effectiveness' can be determined.

The activities of the enzymes gamma-glutamyl-transferase (GGT, aspartate aminotransferase (AST, creatine kinase (CK, alkaline phosphatase (ALP, and lactate dehydrogenase (LDH, serum levels of total calcium, calcium ion, phosphorus, sodium, potassium, magnesium, chlorides, creatinine, uric acid, triglycerides, cholesterol, total protein, albumin, total and indirect and direct bilirubin, and electrophoretic profile of serum proteins in acrylamide (SDS-PAGE and agarose gel were determined. There was no influence of age on total bilirubin and albumin levels. All the other evaluated parameters presented differences in at least one age group. Protein electrophoretic profile also changed as a function of age. The obtained results can be considered as normal for the studied ages, and therefore be used as references for the interpretation of laboratory exams of broilers of this genetic line in the evaluated ages.

    Full Text Available Background: Despite a high prevalence of endometriosis, there still exist many challenges indiagnosing the disease. This study aims to evaluate non-invasive and practical diagnostic methodsby measuring serum and peritoneal fluid CA 125 levels in patients with endometriosis. A secondaryaim is to determine the correlation between these markers with the stage of disease as well as therelationship of the two markers with each other.Materials and Methods: This is a cross-sectional study of 60 women who underwent laparoscopyfor benign conditions. Based on laparoscopic findings and biopsy results, patients were divided to twogroups; one group included patients with pelvic endometriosis (35 patients and the second enrolledpatients free from endometriosis (25 patients. Serum and peritoneal fluid specimens were provided at thetime of laparoscopy and CA125 levels were then assessed by electrochemiluminescence immunoassay.Results: Mean serum and peritoneal fluid CA125 levels were significantly higher in women withendometriosis as compared to the control group (26.42 ± 24.34 IU/ml versus 12.64 ± 6.87 IU/mlin serum and 2203.54 + 993.19 IU/ml versus 1583.42 ± 912.51 IU/ml in peritoneal fluid, p<0.05.CA 125 levels also varied proportionally with the stage of endometriosis; but showed a significantdifference only in higher stages of the disease, both in serum and peritoneal fluid. We calculatedthe cut-off value suggesting a diagnosis of pelvic endometriosis as 14.70 IU/ml for serum and1286.5 IU/ml for peritoneal fluid CA125. A linear correlation between CA 125 levels in serum andperitoneal fluid in patients with pelvic endometriosis has also been observed.Conclusion: Serum and peritoneal fluid CA 125 levels are simple and non-surgical tools fordiagnosing and staging pelvic endometriosis. These markers are of greater diagnostic value inhigher stages of the disease.

    We propose a double antibody radioimmunoassay for human prostatic acid phosphatase (PAP) in serum for diagnosis and management of prostatic adenocarcinoma under treatment. The antigen is purified from human prostatic fluid by a gel-filtration on Sephadex G 100 followed by affinity chromatography on Con A Sepharose. A specific antibody is raised in rabbits and purified by immunoadsorption with a female serum. The described technique offers both radioisotopic sensibility and immunologic specificity. Physiological values determined in the serum of 125 healthy males are below 2 ng/ml. No significative differences are observed with age. The proposed technique also shows significant differences between values evaluated for benign prostatic hyperplasia and prostatic adenocarcinoma [fr

    Science.gov (United States)

    McMillan, John; Walker, Simon; Hope, Tony

    2014-01-01

    This article argues that hope is of value in clinical ethics and that it can be important for clinicians to be sensitive to both the risks of false hope and the importance of retaining hope. However, this sensitivity requires an understanding of the complexity of hope and how it bears on different aspects of a well-functioning doctor-patient relationship. We discuss hopefulness and distinguish it, from three different kinds of hope, or 'hopes for', and then relate these distinctions back to differing accounts of autonomy. This analysis matters because it shows how an overly narrow view of the ethical obligations of a clinician to their patient, and autonomy, might lead to scenarios where patients regret the choices they make.

Age matched 30 non-pregnant women were taken as control. Serum copper level was measured by Spectrophotometric method, serum total protein and albumin levels were estimated by standard method. Statistical analysis was done by one way ANOVA, Bonferroni and Pearson’s correlation coefficient test as applicable.Results: Serum Cu levels were significantly higher in all trimesters of pregnant women compared to control. Again, this value was significantly higher in 3rd trimester than that of in 1st and 2nd trimester and also in 2nd trimester than that of in 1st trimester. In addition, mean serum total protein level was significantly lower in 3rd trimester than control but no statistically significant difference was observed among different trimesters. Again, mean serum albumin level was significantly lower in 2nd and 3rd trimester than 1st trimester and control. In addition, serum Cu concentration showed significant positive correlation with different trimesters of gestation.Conclusion: This study reveals that hypercupremia along with hypoproteinemia occur in pregnant women from 1st to 3rd trimester of gestation. This gradual alteration of micro and macronutrients become more profound with advancement of pregnancy.

    The level of serum alanine aminotransferase (ALT) activity reflects damage to hepatocytes and is considered to be a highly sensitive and fairly specific preclinical and clinical biomarker of hepatotoxicity. However, an increase in serum ALT activity level has also been associated with other organ toxicities, thus, indicating that the enzyme has specificity beyond liver in the absence of correlative histomorphologic alteration in liver. Thus, unidentified non-hepatic sources of serum ALT activity may inadvertently influence the decision of whether to continue development of a novel pharmaceutical compound. To assess the risk of false positives due to extraneous sources of serum ALT activity, additional biomarkers are sought with improved specificity for liver function compared to serum ALT activity alone. Current published biomarker candidates are reviewed herein and compared with ALT performance in preclinical and on occasion, clinical studies. An examination of the current state of hepatotoxic biomarkers indicates that serum F protein, arginase I, and glutathione-S-transferase alpha (GSTalpha) levels, all measured by ELISA, may show utility, however, antibody availability and high cost per run may present limitations to widespread applicability in preclinical safety studies. In contrast, the enzymatic markers sorbitol dehydrogenase, glutamate dehydrogenase, paraxonase, malate dehydrogenase, and purine nucleoside phosphorylase are all readily measured by photometric methods and use reagents that work across preclinical species and humans and are commercially available. The published literature suggests that these markers, once examined collectively in a large qualification study, could provide additional information relative to serum ALT and aspartate aminotransferase (AST) values. Since these biomarkers are found in the serum/plasma of treated humans and rats, they have potential to be utilized as bridging markers to monitor acute drug-induced liver injury in

    This study was designed to evaluate serum bile acid measurements as indicatory, of liver function and/or hepatic fat infiltration in dairy cattle. Serum bile acid concentrations were measured in healthy dairy cattle at different stages of lactation after fasting or feeding. Bile acid concentrations were compared with liver fat content and sulfobromophthalein (BSP) half-life (T 1/2). Serum bile acid concentrations were higher in cows in early lactation and with higher daily milk production. Compared with prefasting values, bile acid concentrations were decreased at 8, 14, and 24 hours of fasting. Blood samples from fed cows at 1- to 2-hour intervals had wide and inconsistent variations in bile acid concentration. Because serum bile acids correlated well with BSP T 1/2, it is suggested that both measurements evaluate a similar aspect of liver function. Neither bile acids nor BSP T 1/2 correlated with differences in liver fat content among cows. Because of large variability in serum bile acid concentrations in fed cows and the lack of correlation of measured values with liver fat content, bile acid determinations do not appear useful for showing changes in hepatic function in fed cows with subclinical hepatic lipidosis nor serve as a screening test for this condition.

  16. Fair Value or Market Value?

    Full Text Available When taking into consideration the issue of defining the “fair value” concept, those less experimented in the area often fall in the “price trap”, which is considered as an equivalent of the fair value of financial structures. This valuation basis appears as a consequence of the trial to provide an “accurate image” by the financial statements and, also, as an opportunity for the premises offered by the activity continuing principle. The specialized literature generates ample controversies regarding the “fair value” concept and the “market value” concept. The paper aims to debate this issue, taking into account various opinions.

    In the last decades, interest has increased in the potential deleterious atherogenic effects of some cellular elastase activities. The results of experimental and clinical investigations were inconsistent. In this report, we assessed the associations of serum elastase activity and serum elastase inhibitors with carotid plaque occurrence during the 4-year follow-up in a population of 859 subjects free of coronary heart disease and stroke (age, 59 to 71 years). Serum elastase activity and serum elastase inhibitors were measured at baseline examination. Carotid B-mode ultrasound examination was performed at baseline and 2 years and 4 years later. The occurrence of carotid plaques in subjects with the lowest serum elastase activity values (quartile 1), in those with the intermediate values (quartiles 2 to 3), and in those with the highest values (quartile 4) was, respectively, 24.6%, 18.9%, and 12.2% (P<0.001 for trend). The multivariate odds ratios of carotid plaque occurrence associated with the three groups (adjusted for major known cardiovascular risk factors) were, respectively, 1.00, 0.67 (CI, 0.44 to 1.02; P<0.06), and 0.40 (CI, 0.23 to 0.70, P<0.001). For serum elastase inhibitors, the occurrence of carotid plaques in quartile 1 (lowest values), quartiles 2 to 3, and quartile 4 (highest values) was, respectively, 11.7%, 18.8%, and 25.2% (P for trend<0.001). The corresponding multivariate adjusted odds ratios were 1.00, 1.98 (CI, 1.19 to 3.31, P<0.01), and 3.18 (CI, 1.80 to 5.60, P<0.001). Low values of serum elastase activity and high values of serum elastase inhibitors were strongly and independently associated with increased 4-year carotid plaque occurrence. Further studies are necessary to elucidate the nature of the associations between elastase parameters and atherosclerosis.

    To compare serum lipid profile between patients of ischaemic and haemorrhagic strokes. Study Design: Cross sectional, comparative study. Place and Duration of Study: Military Hospital, Rawalpindi, from August 2004 to February 2005. Methodology: Patients with diagnosis of stroke comprising 100 consecutive patients each of ischaemic and haemorrhagic strokes were included in the study while patients on lipid lowering therapy were excluded from study. To determine the subtype of stroke, clinical examination followed by CT scan of brain was done. A serum sample after 8 hours of overnight fasting was taken on the next day of admission for both groups of patients. Total serum cholesterol, triglycerides, LDL cholesterol, VLDL-cholesterol and HDL-cholesterol was determined, using enzymatic colorimetric method. Statistical analysis was done by comparison of lipid profile in two subgroups, using proportion test for any significant difference. Results: The mean age at presentation of patients with stroke was 64.2+-12 years with a male to female ratio of 3.6:1. In 100 ischaemic stroke patients, raised serum total cholesterol was seen in 42, triglyceride in 04, LDL-cholesterol in 05 and VLDL-cholesterol in 07 patients. Serum HDL-cholesterol was below the normal reference in 31 cases. On the other hand, serum total cholesterol and triglycerides was raised in 05 patients each, LDL-cholesterol in 09 and VLDL-cholesterol in 03 patients of haemorrhagic stroke. Serum HDL-cholesterol was below normal in 04 patients of haemorrhagic stroke. On comparison, there were significantly greater number of patients with raised serum cholesterol and low HDL-cholesterol in ischaemic stroke than haemorrhagic stroke (p < 0.05). No statistical significance was found on comparing serum values of ischaemic and haemorrhagic stroke for triglycerides, LDL-cholesterol and VLDL-cholesterol. Conclusion: Ischaemic stroke patients had high serum total cholesterol and lower HDL-cholesterol levels as compared to

    1981-01-01

    For 101 hospitalized patients where clinical symptoms of a glucosidine intoxication as a consequence of oral digoxin treatment were noted, serum digoxin levels were determined using a RIA kit of the Boehringer company (I-125 tracer, solid phase tube separation technique) on a fasted stomach prior to oral drug administration. An ECG was performed simultaneously and in addition kidney function parameters and electrolyte levels were determined. An anamnesis and clinical examination of the patients were also conducted. Interferences in the RIA method and gastro-intestinal illness resulting in changes in resorption behaviour were excluded. The group of patients showed collectively an average serum digoxin level of 2.9 +- 0.9 ng/ml with a range from 1.8 to 6.8 ng/ml, which was statistically significantly higher than the average value for 101 patients receiving long-term oral medication but without symptoms of glycosidine intoxication. According to the manufacture's specifications for the RIA kit, values > 2.0 ng/ml are considered as toxic, with values between 1.6 and 2.0 ng/mg falling into a ''grey zone''. A correlation was found between toxic serum values with changes in ECG pattern and subjective clinical symptoms of intoxication. A limitation of kidney function was responsible for the high serum glycoside levels in 62% of the patients. It was shown that the differing response of patients towards digitalis medication, above all in the case of long-term therapy, warrants an RIA determination of serum glycoside values in order to adjust the digoxin dose to individual requirements.

    Vaccination has led to remarkable health gains over the last century. However, large coverage gaps remain, which will require significant financial resources and political will to address. In recent years, a compelling line of inquiry has established the economic benefits of health, at both the individual and aggregate levels. Most existing economic evaluations of particular health interventions fail to account for this new research, leading to potentially sizable undervaluation of those interventions. In line with this new research, we set forth a framework for conceptualizing the full benefits of vaccination, including avoided medical care costs, outcome-related productivity gains, behavior-related productivity gains, community health externalities, community economic externalities, and the value of risk reduction and pure health gains. We also review literature highlighting the magnitude of these sources of benefit for different vaccinations. Finally, we outline the steps that need to be taken to implement a broad-approach economic evaluation and discuss the implications of this work for research, policy, and resource allocation for vaccine development and delivery.

  1. Falsely elevated triiodothyronine values in radioimmunoassay

    1995-01-01

    Five patients with falsely elevated serum triiodothyronine (T 3 ) concentrations (>9 nmol/l) in a radioimmunoassay are reported. The high T 3 -values disagreed with the other thyroid variables investigated as well as with the clinical observations. In sera from all patients a normal non-specific binding of T 3 was found, thus excluding abnormal serum-protein-binding of the hormone. An ethanol extraction of T 3 from serum before RIA reduced the T 3 content in serum from all patients to normal levels (2.0-2.4 nmol/l). These findings indicate the presence in the sera of substances, probably of protein nature, that were interfering with the assay by binding the reagent-antibody and not the antigen. Addition of non-immune rabbit serum prevented this interference and normalized the T 3 -values (1.8-2.4 nmol/l). Thus the interfering substance in T 3 -RIA could be an anti-rabbit antibody, the interaction of which can be eliminated by a minor modification of the assay making it possible to differentiate true from false T 3 -values.

    Objective: To assess usefulness of Minolta Air shield transcutaneous bilirubinometer by comparing bilirubin values obtained by transcutaneous jaundice meter with serum bilirubin estimation. Design: Analytical cross sectional study. Place and duration: NICU Military Hospital Rawalpindi Pakistan Jun 2002 to May 2005. Subjects and Methods: One hundred and fifty neonates admitted to NICU because of visible jaundice were included in the study. Serum was sent to laboratory for total bilirubin estimation. At the same time bilirubin was also checked by a Jaundice Meter. Data was tabulated and t-test applied to compare the two values. Results: One hundred and fifty paired estimations were performed. The transcutaneous bilirubin values ranged from 8.0 mg/dl to 20.4 mg/dl. While serum bilirubin by jaundice meter values ranged between 5.3 mg/dl and 26.0 mg/dl. A Scatter diagram was plotted. It showed a correlation coefficient of 0.78. Conclusion: Bilirubin values obtained by transcutaneous bilirubin meter were not significantly different from laboratory values thus proving the fact that transcutaneous bilirubinometer is a useful device to measure bilirubin.

    1991-01-01

    A simple, fast and reliable liquid chromatographic method for the determination of theophylline in serum and capillary blood after a solid phase extraction is described for therapeutic drug monitoring. The employment of capillary blood permits the determination of an individual drug profile and other pharmacokinetic studies in neonates and infants. There were no differences in venous- and capillary-blood levels but these values compared poorly with those in serum. An adjustment of the results by correction of the different volumes of serum and blood by haematocrit was unsuccessful. Differences in the binding of theophylline to erythrocytes could be an explanation for the differences in serum at blood levels of theophylline.

    The serum-protein changes in lambs given a double dose of irradiated vaccine (40 and 50 kR) were compared with those of non-vaccinated lambs in all the groups. α- and β-globulins were similar but γ-globulins were higher for some weeks in animals given vaccination. Values of serum protein could not be correlated with the vaccine or with the immune status of the animals. In all the animals, the albumin/globulin ratio remained generally well below 1. (auth.)

    Iodine uptake by the thyroid and serum triiodothyronine (T 3 ) level in subjects aged from 65 to 93 years were determined. Low T 3 level and normal uptake of inorganic iodine by the thyroid were found. In the light of these results it is suggested that normal accumulation of inorganic iodine and low production of T 3 are characteristic features of euthyroidism in elderly subjects. It is believed that the function of the thyroid is expressed better by determination of the serum levels of thyroid hormones than determination of the uptake of radioactive iodine. Elaboration of standard normal values which would take into account abnormalities encountered in old age is postulated. (author)

    Serum β 2 -microglobulin (β 2 -MG) was tested by radioimmunoassay in 149 donors' and 54 healthy volunteers' blood. The results were 203 +- 33.0 nmol/l and 176 +- 26.2 nmol/l, respectively. There was significant difference statistically between them (P 2 -MG content. In order to increase the quality of donated blood and to keep the health of blood donor, it is suggested that the high content of serum β 2 -MG is the indicator of too frequent blood donating. The results also showed that the content of β 2 -MG in donor's blood is not a normal reference value

    Although water-soluble vitamins such as thiamine are lost during dialysis session, serum thiamine level tended to restore spontaneously during the hospitalization (25.47±10.07 vs. 27.44±11.37, pre HD value, p=0.09. A three months-follow up measurement after initiation of HD, which is now in progress (so far n=3, revealed increase of serum thiamine level in all patients (35.33±7.37 ng/ml. It may reflect the improvement of nutritional status after the initiation of HD, and suggests the loss of thiamine by HD procedure can be covered.

    The aim of this study was to assess zinc levels in tinnitus patients, and to evaluate the effects of zinc deficiency on tinnitus and hearing loss. One-hundred patients, who presented to an outpatient clinic with tinnitus between June 2009 and 2014, were included in the study. Patients were divided into three groups according to age: Group I (patients between 18 and 30years of age); Group II (patients between 31 and 60years of age); and Group III (patients between 61 and 78years of age). Following a complete ear, nose and throat examination, serum zinc levels were measured and the severity of tinnitus was quantified using the Tinnitus Severity Index Questionnaire (TSIQ). Patients were subsequently asked to provide a subjective judgment regarding the loudness of their tinnitus. The hearing status of patients was evaluated by audiometry and high-frequency audiometry. An average hearing sensitivity was calculated as the mean value of hearing thresholds between 250 and 20,000Hz. Serum zinc levels between 70 and 120μg/dl were considered normal. The severity and loudness of tinnitus, and the hearing thresholds of the normal zinc level and zinc-deficient groups, were compared. Twelve of 100 (12%) patients exhibited low zinc levels. The mean age of the zinc-deficient group was 65.41±12.77years. Serum zinc levels were significantly lower in group III (p<0.01). The severity and loudness of tinnitus were greater in zinc-deficient patients (p=0.011 and p=0.015, respectively). Moreover, the mean thresholds of air conduction were significantly higher in zinc-deficient patients (p=0.000). We observed that zinc levels decrease as age increases. In addition, there was a significant correlation between zinc level and the severity and loudness of tinnitus. Zinc deficiency was also associated with impairments in hearing thresholds.

    To compare serum zinc level between Thalassemia Major (TM) patients and normal population at Shafa Hospital in South West of Iran. A total of 25 male and 36 female of TM patients were enrolled in this study. Out of 61 patients thirty were treated by deferroxamine (DFO) and 31 were on the combination of DFO and deferiprone (DEF) protocol therapy. Sixty normal subjects of the matching age and gender were recruited as controls. From each patient and control group 2 ml of blood was taken in fasting condition. Cell blood count and serum zinc were carried out for both thalassemia patients and normal subjects. The mean age of patients and control group was 15+- 5 years. Mean serum zinc level was 68.97+- 21.12 mu g/dl, 78.10-28.50 mu g/dl, and 80.16+- 26.54 mu g/dl in the TM with DFO, TM with DFO + DEF combination protocol and control group respectively. There was no significant correlation between patients and control group. However 50 percent of TM with DFO, 38.7 percent of TM with DFO + DEF and 32.8 percent of control group had hypozincemia. Nearly 40 to 50 percent of TM patients and one third of normal subjects are suffering from hypozincemia. This study shows that low level of serum zinc is a health problem in both thalassemia patients and normal population in South West of Iran. (author)

    Purpose: To evaluate the role of PET-CT with FDG-{sup 18}F in the detection of recurrence and/or metastasis of differentiated thyroid carcinoma (DTC) in patients with elevated levels of thyroglobulin (TG) and negative whole body scan (WBS). Patients and method: PET-CT findings of 25 patients were compared to histopathology evaluation and conventional imaging (CI). Results: PET-CT scan was positive in 16 patients finding 14 true-positive and 2 false-positive cases (positive predictive value 87.5%). Nine patients had negative PET-CT; two had decrease of TG to undetectable levels. One patient had residual disease detected by post-therapeutic WBS. Six patients had no evidence of tumor during follow-up (mean time 16 months). PET-CT was concordant with CI in 52%, partially concordant in 12% and discordant in 36% (6 false-negatives and 3 false-positive of CI). We observed a tendency of increasing proportion of positive PET-CT with increasing TG. Conclusion: PET-CT scan with FDG-{sup 18}F is useful in the detection of recurrence and/or metastases of DTC with high TG levels but negative WBS. It presents elevated positive predictive value and is superior to CI being more effective as higher the serum TG levels. (author)

    To explore the clinical value of the serum β-HCG (human chorionic gonadotrophin) in the conservative treatment of ectopic pregnancy, the serum β-HCG levels in 118 patients with ectopic pregnancy were measured with RIA. The results showed that the serum β-HCG levels in patients with successful conservative treatment of ectopic pregnancy were all less than 200mIU/mL. The patients require a surgical treatment to reach <200mIU/mL serum β-HCG concentration were only 26.3%. There was significant difference between two groups (P<0.01). The monitoring of serum β-HCG was very useful in the diagnosis, the choice of treatment measures and the evaluation of conservative treatment effect of ectopic pregnancy. In the course of treatment of ectopic pregnancy, serum β-HCG is a good marker in determining the success or failure of treatment. (authors)

    Antiserum raised in rabbits against the FBP obtained from CML cells, and the purified binder labeled with 125 I, have been used for an RIA which can measure an immunologically similar protein in human serum. The concentration of the binding protein in normal serums ranged from 1.2 to 9.3 ng/ml, with a mean +- S.E.M. of 3.8 +- 0.4 ng/ml. Elevated values of the binder protein were measured in the serums from patients with folate deficiency, vitamin B 12 deficiency, liver disease, uremia, myeloproliferative diseases, chronic lymphocytic leukemia, and various types of cancer and in the serum from pregnant women. The concentration of the binder protein and the capacity of the serum to specifically bind isotopically labeled PGA correlated poorly, indicating that the binding protein concentration and degree of saturation by endogenous serum folate vary independently in many instances

    In order to investigate the feasibility of serum creatine kinase (CK) and blood urea nitrogen (BUN) in monitoring pre-competition training of badminton athletes, the pre-competition training load of 20 badminton athletes was studied, and serum CK and BUN were determined before, immediate and next morning after training. The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L (P0.05). After intermittent training, there was significant difference in the average increased levels of serum CK in athletes (P0.05). It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.

    The diagnosis of borderline hyperthyroidism is difficult. A sensitive radioimmunoassay capable of detecting subnormal levels of serum TSH may be of value in confirming this diagnosis because of the suppressed pituitary function in this disease state. This sensitive assay may also be useful in monitoring the suppression of pituitary function in thyroid cancer patients receiving thyroid hormone therapy. A sensitive radioimmunoassay capable of detecting serum TSH levels as low as 0.25 μU/m1 with coefficients of variation less than 17.2% was used to measure serum TSH levels in 80 healthy subjects, 44 hyperthyroid patients, and 25 athyrotic thyroid cancer patients on daily suppressive doses of thyroxine. All healthy subjects had detectable TSH levels with a mean value of 1.17 and two standard deviation ranges of 0.41 - 2.70 μU/m1 (lognormal distribution). Although the mean +-1 SEM value of 0.63 +- 0.003 μUm1 for hyperthyroid patients and 0.76 +- 0.08 μU/ml for thyroid cancer patients were significantly lower than that of healthy subjects (t-test, p<0.05), subnormal levels of serum TSH were found in only 28.6% (12/42) and 24% (6/25) of hyperthyroid and thyroid cancer patients, respectively. TSH stimulation tests performed in 6 of the cancer patients all gave suppressed responses. Because of considerable overlap, serum TSH levels alone cannot distinguish hyperthyroidsm from euthyroidism. However, a sensitive TSH radioimmunoassay such as the one described here may be of value in evaluating the extent of pituitary suppression in thyroid cancer therapy

  17. Erysipelothrix rhusiopathiae and Mycoplasma hyopneumoniae: the sensitivities of enzyme-linked immunosorbent assays for detecting vaccinated sows of unknown disease status using serum and colostrum, and the correlation of the results for sow serum, colostrum, and piglet serum.

    Due to relatively high concentrations of immunoglobulins, colostrum has the potential to improve the sensitivity of diagnostic tests for diseases in pigs when compared with serum. It is possible that colostrum could improve the sensitivity of the antibody enzyme-linked immunosorbent assay (ELISA) compared with serum. Colostrum is also essential for piglets, providing protection against infections in the first few weeks and months of life. The sensitivity of 2 commercially available ELISAs, one for the detection of Erysipelothrix rhusiopathiae and the second for Mycoplasma hyopneumoniae antibodies, when used with sow colostrum in comparison with serum was investigated. The correlation of maternal E. rhusiopathiae- and M. hyopneumoniae-specific antibody levels with specific-antibody serum levels in the piglet was also determined. The sensitivity was defined as the proportion of vaccinated sows that were correctly identified as vaccinated at a given cutoff point. The true disease status of the sows with regard to the 2 infections was unknown. Blood and colostrum samples were collected from 20 sows, 10 primiparous and 10 multiparous, and blood samples were also collected from the piglets of each sow, 48-72 hr post-farrowing. The sensitivities of both ELISAs were significantly improved when using colostrum compared with serum. Sow serum and colostrum optical density (OD) values were significantly correlated. The mean sow OD values for serum for E. rhusiopathiae and M. hyopneumoniae and colostrum for E. rhusiopathiae were significantly correlated with piglet serum OD levels. If the improved sensitivity of colostrum can be demonstrated in infected animals, this will increase the ability of the test to identify infected animals using both individual and pooled colostrum. Testing serum and/or colostrum using ELISA can be useful predictors of piglet disease-specific OD values. © 2015 The Author(s).

    Chronic metabolic acidosis leads to bone mineral loss and results in lower bone mineral density (BMD), which is a risk factor for osteoporosis-related fractures. The effect of low-level metabolic acidosis on bone density in the general population is unknown. Cross-sectional study. 9,724 nationally representative adults 20 years or older in NHANES (National Health and Nutrition Examination Survey) 1999-2004. Serum bicarbonate level. Lumbar and total BMD, as well as low lumbar and total bone mass, defined as 1.0 SD below the sex-specific mean value of young adults. BMD was measured by dual-energy x-ray absorptiometry and serum bicarbonate was measured in all participants. Both men and women with lower serum bicarbonate levels were more likely to be current smokers and had higher body mass index and estimated net endogenous acid production. There was a significant linear trend across quartiles of serum bicarbonate with lumbar BMD in the total population, as well as in sex-specific models (P=0.02 for all 3 models, P=0.1 for interaction). For total BMD, a significant association was seen with serum bicarbonate level for women but not men (P=0.02 and P=0.1, respectively; P=0.8 for interaction), and a significant association was seen for postmenopausal women but not premenopausal women (P=0.02 and P=0.2, respectively; P=0.5 for interaction). Compared with women with serum bicarbonate levels <24mEq/L, those with serum bicarbonate levels ≥27mEq/L had 0.018-g/cm(2) higher total BMD (95% CI, 0.004-0.032; P=0.01) and 31% lower odds of having low total bone mass (OR, 0.68; 95% CI, 0.46-0.99; P=0.049). Cross-sectional study using a single measurement of serum bicarbonate. Subgroup differences are not definitive. Lower serum bicarbonate levels are associated with lower BMD in US adults. Further studies should examine whether serum bicarbonate levels should be incorporated into the diagnostic assessment and management of osteoporosis. Copyright © 2015 National Kidney Foundation

    1975-01-01

    Rabbits were irradiated once with 1000R over the whole body, and the following results were obtained. 1) The whole lipid content of serum: The whole lipid content was found to have increased about 2.6 times 24 hours after irradiation, and even after a lapse of 48 hours such a tendency persisted. 2) Serum whole TBA level: 24 hours after irradiation the whole TBA level had increased markedly up to about 6.5-fold of that before irradiation. 3) Lipid content of fraction: Especially marked in the increase in triglyceride. 4) TBA level of fractionated lipid: There is seen a marked increase in cholesterol ester, which practically occupied the entire serum TBA value. Next marked was the increase in phospholipid, and quantitatively it was classified that the increases seen in triglyceride and free fatty acids are not concerned with the rise in the free fatty acid content and TBA level. 5) Serum lipid contents and TBA level in fasting: By taking the level of serum lipid 24 hours after the start of fasting as one, the serum lipid levels were studied at 48 and 72 hours after the start of fasting, and it was found that both serum lipid and TBA levels rose only very slightly. 6) Changes in fatty acids: The relative ratio of palmitic acid to the whole fatty acids increased after irradiation, and the ratios of linolic acid and linolenic acid were decreased by irradiation while by 48 hours the relative ratio of linolic acid was decreased to about 1/5 of that before irradiation, and the relative ratio of linolenic acid was markedly decreased to about 1/35.

    Full Text Available BACKGROUND : Neonates receiving phototherapy have side effects like hypocalcemia and electrolyte changes. Our study is hereby intended to study the serum sodium changes due to phototherapy. AIMS : To evaluate the serum sodium changes in neonates receiving phototherapy f or neonatal hyperbilirubinemia. SETTINGS AND DESIGN : A prospective hospital based comparative study conducted on neonates admitted in the Neonatal Intensive Care Unit receiving phototherapy. METHODS AND MATERIAL : A predesigned proforma has aided the enroll ment of 252 newborns into the study. Serum bilirubin and serum sodium were determined before and after termination of phototherapy. The first samples were considered as controls. A comparative study was made between before and after phototherapy groups to determine the incidence of serum sodium imbalances. STATISTICAL ANALYSIS USED : Proportions will be compared using chi - square test. All data of various groups will be tabulated and statistically analyzed using suitable statistical tests (Student's t test. RESULTS : Male to Female ratio was 1.45 : 1. Incidence of low birth weight babies was 23% and preterm was 20.2%. Mean birth weight and gestational age was 2.84±0.51 kg and 38.44±1.98 wks respectively. Mean duration of phototherapy was 37.65±11.06 hrs. The incidence of hyponatremia post phototherapy found to be 6% which was more in low birth weight (LBW babies (17.2% , p48 hrs (p<0.001. Even the decline in mean serum sodium values after phototherapy found to be statistically significant. CONCLUSION : Our study shows that neonates u nder phototherapy are at higher risk of hyponatremia. This risk is greater in premature and LBW babies and hence this group of babies should be closely monitored for changes in serum sodium and should be managed accordingly.

    The production of highly specific antisera for T 3 and the development of a sensitive radioimmunological procedure for the direct measurement of T 3 in serum is described. Anti-T 3 sera were produced by immunizing rabbits with conjugates of T 3 and bovine albumin, human albumin, and ovalbumin. The various antisera produced showed very little variance in quality and could be used for the direct radioimmunological determination of serum-T 3 with final dilutions between 1:60,000 and 1:300,000. Binding of T 3 to thyroid-hormone-binding serum proteins was inhibited by 8-anilinonaphthalene-1-sulfonic acid. This compound showed better inhibition properties than merthiolate and sodium salicylate. The separation of free and bound hormone was performed by the double antibody technique. The separation by dextran-coated charcoal and ion-exchange resin leads to a decrease of the antibody-bound activity. The validation of the method used was tested by serial dilutions of sera, recovery experiments, and by comparing the serum-T 3 values measured in ethanol extracts with those values obtained by the direct measurement in unextracted serum. The lower limit of detection was approximately 0.18 nmol/l serum. The variation coefficient for the intraassay reproducibility was between 4.3 and 6.1%, for the interassay reproducibility between 7.7 and 13.9%. Measured mean T 3 concentrations for various thyroid states were as follows: Normals: 1.77 nmol/l (1.15 μg/l), normal females on contraceptives: 2.03 nmol/l (1.32 μg/l), pregnants: 2.73 nmol/l (1.78 μg/l), hyperthyroidism: 6.30 nmol/l (4.10 μg/l), T 3 -toxicosis: 3.69 nmol/l (2.40 μg/l). In hypothyroidism T 3 ranged from [de

  4. PLAC1 as a serum biomarker for breast cancer.

    Directory of Open Access Journals (Sweden)

    Hongyan Yuan

    Full Text Available Placental-specific protein 1 (PLAC1 is an X-linked trophoblast gene that is re-expressed in several malignancies, including breast cancer, and is therefore a potential biomarker to follow disease onset and progression. Sera from 117 preoperative/pretreatment breast cancer patients and 51 control subjects, including those with fibrocystic disease, were analyzed for the presence of PLAC1 protein as well as its expression by IHC in tumor biopsies in a subset of subjects. Serum PLAC1 levels exceeded the mean plus one standard deviation (mean+SD of the level in control subjects in 67% of subjects with ductal carcinoma in situ (DCIS, 67% with HER2+ tumors, 73% with triple-negative cancer and 73% with ER+/PR+ tumors. Greater sensitivity was achieved using the mean+2 SD of control PLAC1 serum values, where the false positive rate was 3% and was exceeded by 38%, 40%, 60% and 43% of subjects with DCIS, HER2+, TNBC and ER+/PR+/HER2- tumors. PLAC1 was detected in 97% of tumor biopsies, but did not correlate quantitatively with serum levels. There was no significant correlation of serum PLAC1 levels with race, age at diagnosis, body mass index (BMI or the presence of metastatic disease. It remains to be determined whether PLAC1 serum levels can serve as a diagnostic biomarker for the presence or recurrence of disease post-surgery and/or therapy.

    Aluminium is produced from the mineral bauxite. Occupational exposure is reported during the industrial processing of aluminium and is associated with pulmonary and neurotoxicity. However, data on exposure and toxicity of workers in the open bauxite mining industry do not exist. Therefore, a study was performed to explore aluminium exposure in employees involved in this bauxite mining process in a Surinam mine. A group of workers occupationally exposed to aluminium in an open bauxite mine were compared with a group of nonexposed wood processors. Serum aluminium was analyzed using atomic absorption spectrometry Data from the clinical chemistry of the blood and a questionnaire were used to explore determinants for aluminium exposure. No significant difference between serum aluminium in the exposed (4.4 +/- 2.0 micrograms/L, n = 27) and control group (5.1 +/- 1.5 micrograms/L, n = 27) was detected. For the serum concentration of the clinical chemical variables (calcium, citrate, and creatinine), a statistically significant difference was computed (p < or = 0.02) between the exposed and control group. All levels were slightly higher in the exposed group; no statistically significant correlations with serum aluminium were found. In this study, serum aluminium values were in the normal range, no significant difference between the groups could be detected despite long-term occupational exposure.

    Extensive previous studies have demonstrated that attempts to produce polymers of Hymenoptera venoms for human immunotherapy resulted in insoluble precipitates that could be injected with safety but with very limited immunogenicity in allergic patients. We now report soluble polymers prepared by conjugating bee venom with human serum albumin with glutaraldehyde. The bee venom-albumin polymer (BVAP) preparation was fractionated on Sephacryl S-300 to have a molecular weight range higher than catalase. /sup 125/I-labeled bee venom phospholipase A was almost completely incorporated into BVAP. Rabbit antibody responses to bee venom and bee venom phospholipase A were induced by BVAP. Human antisera against bee venom were absorbed by BVAP. No new antigenic determinants on BVAP were present as evidenced by absorption of antisera against BVAP by bee venom and albumin. BVAP has potential immunotherapeutic value in patients with anaphylactic sensitivity to bee venom.

    A glycoprotein designated CX 1, of molecular weight 80,000, has been extracted from adenocarcinomas of the ovary and its measurement by radioimmunoassay established. CX 1 is present in the normal ovary and in normal serum. It is present in various non-ovarian carcinomas but in much greater amount in ovarian adenocarcinoma and in ascitic fluid associated with this cancer. Increased concentrations are found in the serum of patients with various cancers. In about 60% of patients with Stage III and IV ovarian adenocarcinoma, serum values are elevated and they correlate with the course of the disease, providing information which probably has clinical value.

    2012-01-01

    Background: Leptin is product of ob gene, an adipose tissue derived hormone that plays a key role in the regulation of body fat mass by regulating appetite and metabolism while balancing energy intake and energy expenditure. The objective of the study was to evaluate possible association between serum leptin levels and Body Mass Index (BMI) of gender in adult age group. Methods: Two-hundred-seventy subjects aged 20-50 years were randomly selected from general population of Abbottabad. The subjects were grouped on the basis on BMI (89 normal, 92 overweight, and 89 obese). After complete evaluation, demographic data was recorded and BMI. Non-fasting venous blood samples were drawn to measure serum leptin and serum glucose levels. The data were analysed using SPSS-15 calculating mean, percentage, independent t-test and chi-square test. Correlation and regression curve analysis were obtained, and p and r values were calculated. Results: Serum leptin levels and differences between genders were significant in all body mass indices. For normal BMI group the mean values for leptin were 2.6+-1.5 gamma g/ml in men, and 17.3+9-10.2 gamma g/ml for women. For Group-2 mean leptin levels in men were 9.9+-6.8 gamma g/ml and in women were 34.8+-13.6 gamma g/ml. For Group-3 BMI comprising obese subjects mean values for men were 21.3+-14.2 gamma g/ml and for women were 48.21+-21.2 gamma g/ml (p<0.001). Conclusion: A progressive increase in serum leptin concentration was observed with an increase in BMI. Significant difference between leptin concentrations in either gender was found in normal, overweight and obese subjects. (author)

    To study afternoon serum-melatonin values in patients with sleep disordered breathing. Melatonin has a strong circadian rhythm with high values during the night-time and low values in the afternoon. Sleep disordered breathing may change the circadian rhythm of melatonin which may have diagnostic implications. The Sleep Laboratory, The Department of Internal Medicine, Avesta Hospital, Sweden, and the Department of Anaesthesiology, Glostrup University Hospital, Copenhagen, Denmark. We examined 60 consecutive patients admitted for sleep disordered breathing and 10 healthy non snoring controls. The patients underwent a sleep apnoea screening test having a specificity of 100% for the obstructive sleep apnoea syndrome (OSAS) using a combination of static charge sensitive bed and oximetry. Obstructive sleep apnoea syndrome was found in 49 patients, eight patients had borderline sleep disordered breathing (BSDB) and three patients were excluded due to interfering disease. Patients and controls had an afternoon determination of serum-melatonin. The Epworth Sleepiness Scale was used to score day-time sleepiness. In comparison with normal controls patients suffering from OSAS had significantly higher serum-melatonin levels in the afternoon. However, as a diagnostic test for OSAS in patients with sleep disordered breathing serum-melatonin showed a low sensitivity but a high specificity. The results indicate that breathing disorders during sleep in general affect pineal function. Sleep disordered breathing seems to disturb pineal function. Determination of afternoon serum-melatonin alone or together with a scoring of daytime sleepiness does not identify OSAS-patients in a heterogeneous population of patients complaining of heavy snoring and excessive daytime sleepiness.

    Laboratory parameters can help in the differential diagnostics of acute episodes of transient loss of consciousness. Especially serum lactate and serum creatine kinase (CK) levels may provide valuable hints to distinguish generalized tonic-clonic seizures (GTCS) from syncope. Serum lactate levels at admission and CK levels 10-48 h after the episodes that led to admission were compared between patients with GTCS (n = 30) and those with syncope (n = 15). In addition, sensitivity and specificity of lactate and CK as diagnostic markers for syncope and GTCS were determined. The serum lactate and serum CK levels were significantly increased in patients with GTCS as compared to syncope patients (serum lactate: p lactate as an indicator for GTCS was 0.94 (95% confidence interval [CI] 0.88-1.0). For CK the receiver operating characteristics (ROC) analysis produced an AUC of only 0.77 (95% CI: 0.63-0.9). The determination of the lactate value as point-of-care diagnostics appears to be highly relevant in the rapid clarification of unclear episodes with transient loss of consciousness. The CK level at follow-up is also suitable for distinguishing GTCS from syncope but is inferior to the serum lactate value.

    Objective: To investigate the importance of determination of changes of serum procalcitonin (PCT) and IL-6 levels in patients with sepsis. Methods: Serum PCT (with double-sandwich immunofluorescence assay) and IL-6 (with ELISA) levels were measured repeatedly in 130 patients with sepsis on d1, d3, d5, d7 after admission. Values in 130 healthy individuals were also measured as control. Results: The serum levels of PCT and IL-6 in the patients with sepsis of admission were significantly higher than those in controls. The levels dropped markedly in the survivors by d7. Among the septic patients, the levels in the succumbed patients were significantly higher those in the survivors (P<0.05). Conclusion: Serum PCT and IL-6 values appeared to be of prognostic value in patients with sepsis. (authors)

    A method for the measurement of rT 3 in serum by radioimmunoassay is presented. The double antibody plus polyethylene glycol was used as separating reagent. The method is simple, precise and sensitive. Serum rT 3 values of normal (n = 61) were 47.7 ± 11.34 x 10 -8 g/L (X-bar ± SD). Patients with hyperthyroidism (n = 8) serum rT 3 values were 272.2 ± 91.1 x 10 -8 g/L (X-bar ± SD) and patients with hypothyroidism (n = 2) serum rT 3 values were 11.4 ± 8.3 x 10 -8 g/L (X-bar ± SD). It appears to be a useful diagnostic procedure for thyroid diseases

    At the ABCC clinic in Hiroshima 1330 subjects were investigated as to serum pepsin levels over a four month period. The normal mean values compared well with those reported for a United States population using a similar technique. There appeared to be no significant change in serum pepsin level with age, and no difference could be detected among individuals of the ABO blood groups. No relationship was found between serum pepsin level and exposure to ionizing radiation. Patients with gastric and duodenal ulcers had mean levels which were higher than normal mean values, while patients with leukemia had lower than normal mean levels. Patients with gastric polyps and gastric cancer had normal mean values. It is believed that the relation of serum pepsin activity to cancer of the stomach is not settled and deserves further investigation. 23 references, 2 figures, 4 tables.

    Full Text Available The present study was undertaken to compare serum and salivary biochemical constituents during lactation and dry period in dairy cows. Also, the present study evaluated for the first time the salivary biochemical constituents in dairy cows. The study was carried out using 45 healthy multiparous Holstein cows maintained in dairy farms located in Morioka city (Iwate prefecture, Japan. Cows were classified into groups based on the month of lactation. Serum, saliva and milk samples were collected and analyzed. Data were statistically analyzed and the variation in serum and salivary biochemical constituents during lactation and dry period were discussed. From the present study, it could be concluded that the 1st month of lactation has the highest levels for serum free fatty acids (FFA, β- Hydroxy butyric acid (BHBA and aceto Acetic acid (ACAC. The dry period has the highest serum glucose level and the lowest serum FFA, BHBA and aspartate aminotransferase levels. Both serum and salivary FFA showed the highest value during the 1st month of lactation. Saliva contains a high level of gamma glutamyl transferase. The level of ammonia in saliva is higher than its serum level during all months of lactation and dry period. Most of the biochemical constituents in saliva change in different way from serum during lactation and dry period. Milk protein/fat ratio of 0.7 may be not indicative for subclinical ketosis.

    Full Text Available Purpose: We investigated the correlations of serum total testosterone (TT levels with body composition and physical fitness parameters in patients with erectile dysfunction (ED to know the best exercise for testosterone deficiency. Materials and Methods: Eighty-seven ED patients underwent serum TT assessment as well as body composition and basic exercise testing. The bioelectrical impedance analysis was used to assess body composition. Seven types of basic exercise tests were used to determine physical fitness. Correlations between serum TT levels and body composition/physical function parameters were evaluated using partial correlation analyses. A serum TT cut-off value was obtained for the parameters significantly correlated with serum TT levels. Results: The subjects had a mean serum TT level of 342.1 ng/dL. Among the body composition parameters, body and abdominal fat percentages showed statistically significant negative correlations with serum TT levels. Among the basic exercise test parameters, only the cycle ergometer test for cardiorespiratory fitness showed a statistically significant positive correlation with serum TT levels. Conclusions: Serum TT levels in patients with ED, may be increased by reducing fat percentage and improving cardiorespiratory fitness via aerobic exercise.

    Full Text Available Noise, one of the main components of modern society, has become an important environmental problem. Noise is not only an irritating sound, but also a stress factor leading to serious health problems. In this study, we have investigated possible effects of rosuvastatin, a 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor, thought to have an antioxidant effect, on noise-induced oxidative stress in the serum of rat models. Thirty-two male Wistar albino rats were used. In order to ease their adaptation, 2 weeks before the experiment, the rats were divided into four groups (with eight rats per each group: Noise exposure plus rosuvastatin usage, only noise exposure, only rosuvastatin usage and control. After the data had been collected, oxidant (Malondialdehyde, nitric oxide [NO], protein carbonyl [PC] and antioxidant (superoxide dismutase [SOD], glutathione peroxidase [GSH-PX], catalase [CAT] parameters were analyzed in the serum. Results indicated that SOD values were found to be significantly lower, while PC values in serum were remarkably higher in the group that was exposed to only noise. GSH-Px values in serum dramatically increased in the group on which only rosuvastatin was used. During noise exposure, the use of rosuvastatin caused significantly increased CAT values, whereas it resulted in reduced PC and NO values in serum. In conclusion, our data show that noise exposure leads to oxidative stress in rat serum; however, rosuvastatin therapy decreases the oxidative stress caused by noise exposure.

    To evaluate the diagnostic value of the ratio of serum thyroxine(T 4 ) /thyroxine-binding globulin (TBG) for the thyroid status in pregnancy and newborn serum thyroxine, TBG, triiodothyronine, and free thyroxine levels were radioimmunoassayed in normal pregnant women at each of the trimesters, and the calculated serum T 4 /TBG ratios were compared with other parameters such as T 3 /TBG ratio and free T 4 /TBG ratio and free T 4 /TBG ratio. Serum T 4 levels were elevated with the proportionate increase in TBG levels during pregnancy, leading to the nearly constant value of serum T 4 /TBG ratios as in normal non-pregnant controls. In contrast, serum T 3 /TBG and free T 4 /TBG ratios varied considerably during pregnancy. In newborn, T 4 levels were nearly not changed with compared non-pregnant control value and TBG levels were elevated. The results indicate that serum T 4 /TBG ratio is a better parameter than others in evaluating the thyroid status during pregnancy and but newborn is a no better.

    Full Text Available Background and objective The detection of serum tumor markers is of great value for early diagnosis of lung cancer. The aim of this study is to summarize the clinic significance characteristics of serum markers contributing to the detection of lung cancer. Methods References about serum markers of lung cancer were estimated using meta-analysis method. 712 references which included more than 20 cases, 20 controls, the serum markers of 52 832 patients with malignancies and 32 037 patients as controls were evaluated. Results Overall the detection of 13 markers play a significant part in lung cancer diagnosis. The sensitivity of CEA, CA125, CYFRA21-1, TPA, SCCAg, DKK1, NSE, ProGRP in the patients’ serum with lung cancer were 47.50%, 50.11%, 57.00%, 50.93%, 49.00%, 69.50%, 39.73%, 51.48% and the specificity were 92.34%, 80.19%, 90.16%, 88.41%, 91.07%, 92.20%, 89.11%, 94.89%. In the combined analysis of tumor markers: the sensitivity, specificity of NSE+ProGRP were 88.90% and 72.82% in diagnosis of small cell lung cancer, respectively. In diagnosis of squamous corcinoma, the sensitivity and specificity of TSGF+SCCAg+CYFRA21-1 were 95.30% and 74.20%. The the sensitivity and specificity of CA153+Ferrtin+CEA were 91.90% and 44.00% in diagnosis of lung cancer. Conclusion Although the assay of tumor markers in serum is useful for diagnosis of early lung cancer, the sensitivity and specificity are low. Combined detection of these tumor markers could increase sensitivity and specificity.

    Full Text Available Background: Recent epidemiological studies demonstrate that obesity is associated with an increased risk for breast cancer in women. Increased estrogen levels are suggested as one possible explanation, but this does not fully explain the relationship between obesity and breast cancer. One alternative explanation is secretion by adipocytes of metabolites, hormones and cytokines, collectively known as adipocytokines, which regulate physiological and pathological processes. Among these adipokines are visfatin and resistin. This study investigates whether visfatin or resistin in serum of breast cancer patients can be used as potential diagnostic and prognostic tools for breast cancer, taking into account clinicopathological features and anthropometric parameters. Methods: Blood samples were collected from 70 breast cancer patients (35 obese and 35 non-obese and 20 healthy females matched for age and body mass index as the control group. Serum visfatin levels were measured by enzyme linked immunosorbent assay and serum resistin levels were measured by radioimmunoassay. Inflammatory status was assessed by measuring C-reactive protein levels by an automated turbidimetric analyzer. Results: We observed highly elevated serum resistin and visfatin levels in breast cancer patients compared to controls, independent of body mass index. Serum resistin and visfatin levels were likely to be associated with increased breast cancer risk and correlated with the inflammatory marker C-reactive protein. Conclusion: Targeting resistin and visfatin inhibition can be an effective therapeutic strategy in breast cancer by downregulating the inflammatory microenvironment in breast tissue. Serum visfatin promises to be a novel biomarker of diagnostic and prognostic value. Larger prospective studies are required to confirm our findings.

    C-peptide and insulin serum determinations were performed in 94 glucagon-stimulated diabetics and in 15 healthy persons. A minimal increase of 1.5 ng C-peptide/ml serum after glucagon injection (1 mg i.v.) was found to be a useful parameter for the differentiation of insulin dependent and non-insulin dependent diabetics. The maximal response to glucagon occurred during the first 10-minutes after the injection (blood was drawn at 2-minutes intervals). Serum insulin levels and basal C-peptide concentrations were of no value in predicting insulin-dependency. Basal C-peptide levels were significantly different from control in juvenile insulin dependent diabetics (decrease) only. (Author)

    Full Text Available Serum enzyme levels were determined in goats of Marwari breed belonging to farmers’ stock of arid tract of Rajasthan state, India. The animals were grouped into healthy and stressed comprising of gastrointestinal parasiticised, pneumonia affected, and drought affected. The serum enzymes determined were sorbitol dehydrogenase, malate dehydrogenase, glucose-6-phosphate dehydrogenase, glutamate dehydrogenase, ornithine carbamoyl transferase, gamma-glutamayl transferase, 5’nucleotidase, glucose-6-phosphatase, arginase, and aldolase. In stressed group the mean values of all the enzymes increased significantly (p≤0.05 as compared to respective healthy mean value. All the enzymes showed highest values in the gastrointestinal parasiticised animals and least values in the animals having pneumonia. In gastrointestinal parasiticised animals maximum change was observed in G-6-Pase activity and minimum change was observed in malate dehydrogenase mean value. It was concluded that Increased activity of all the serum enzymes was due to modulation of liver functions directly or indirectly.

    To determine the frequency of electrolyte disturbances in malnourished children with and without diarrhea and whether these findings have therapeutic value or not. It is a descriptive study conducted at pediatric Unit-II LUH Hyderabad, from 1st August to 31st September 2004. One hundred children of protein-calorie-malnutrition between 6 months to 5 year of age of either sex who were admitted due to diarrhoea, failure to thrive, acute respiratory infection, malaria, anemia, cardiac failure and feeding problems were included in the study. On the basis of history, physical examination and anthropometrics measurement they were divided into Group A patients (n=64) who were malnourished but had diarrhoea and Group B patients (n=36) who were also malnourished and had no diarrhoea. Serum electrolytes were done in patients of both groups and the results were analyzed statistically. Analysis of serum electrolyte in both groups revealed that hypokalemia, hyponatremia and low serum bicarbonate were seen more frequently in patients of group A as compared to group B. In group A hypokalemia was seen in 40 patients(62.5%) while it was observed in 8 patients (22.22%) in group B (p<0.001), hyponatremia was seen in 17 patients (26.56%) in group A and in 5 patients (13.88%) in group B (p<0.001). In group A 41 patients (64%) had low serum bicarbonate while in group B only 15 patients (41.66%) had low serum bicarbonate value (p<0.001) Electrolyte changes were commonly seen in grade II and III malnourished patients particularly who presented with diarrhoeal episode of variable duration. If these changes are diagnosed in time and treated appropriately the morbidity and mortality could be decreased. (author)

    Total reflection x-ray fluorescence was applied in the analysis of a pool human blood serum sample, which was collected out of 100 healthy individuals during an ordinary day at a hospital in Athens. Direct measurements of 4 1 quantities were performed in a standard TRXRF module, but with the addition of a Mo filter after the cut-off reflector. In this way the exciting beam was further monochromatized leading to an improved peak to background ratio. The elements S, Cl, K, Ca, Fe, Cu, Zn, Se, Br, Rb were detected, with detection limits in the low ppb region for the elements of interest. The determined trace elements concentrations were found to be in very good agreement with values already reported in literature. For intercomparison a quantity of the same sample was freeze dried and measured in a secondary target assembly, in the form of pellets, giving almost identical results. The trace elements concentrations obtained can be considered as representative values for healthy population of Athens and therefore can be used as a monitor in order to associate the lack or excess of certain trace elements with pathological cases.

    This study investigated plasma carnitine levels in patients undergoing allogenic bone marrow transplantation. The patients received fat-based TPN (50% fat, 50% CHO; calorie: nitrogen ratio 125:1) for an average of 33 +/- 7.5 days. TPN was started before transplantation and stopped when patients were able to eat. Caloric needs were estimated using the Harris-Benedict equation; 150% of the estimated BEE was given for the first two weeks after transplantation. The amount of TPN was gradually decreased as patients resumed their oral intake. All patients had low-normal serum carnitine levels before transplantation. There was no significant change in total or free serum carnitine levels during the course of TPN. However, in patients who had symptoms of graft vs. host reaction (GVH), the highest carnitine values during GVH (total 72.3 +/- 6.5 and free 61.2 +/- 12.4 mumol/l) were significantly higher (p < 0.001) than the baseline values (total 27.1 +/- 9.3 and free 24.9 +/- 9.6 mumol/l) or the highest non GVH values after transplantation (total 32.0 +/- 10.7 and free 29.0 +/- 10.7 mumol/l, respectively). The serum triglyceride, total cholesterol, and HDL cholesterol remained within normal range. In conclusion, bone marrow transplant patients receiving fat-based TPN have normal circulating levels of carnitine. GVH reaction caused an increase in the carnitine levels, which was probably due to increased tissue catabolism.

    1977-01-01

    A specific radioimmunoassay for 3,3'-diiodothyronine (T 2 ) is described which is capable of detecting as little as 1.3 ng/dl. The antiserum recognizes mainly T 2 ; biliary conjugates of T 2 bind slightly to the antibody. The intraassay and interassay coefficients of variation were, respectively, 5.7% and 13.1%. T 2 was detected in the serum of hypothyroid patients treated with triiodothyronine (T 3 ) and in euthyroid subjects treated with reverse triiodothyronine (rT 3 ). These results suggest that both T 3 and rT 3 are deiodinated to T 2 . Serum concentrations of T 2 in normal subjects decreased with age. Between 20 and 40 years the mean concentration was 4.3 +- 2.0 ng/dl (2 SD), between 41 and 60 years it varied from 1.9 to 5.8 ng/dl (3.8 +- 0.3 ng/dl, SE) and in elderly subjects have 60 years concentrations varied from unmeasurable to 4 ng/dl (2.9 +- 0.4 ng/dl, SE). Low serum T 2 concentrations were found in anorexia nervosa (2.5 +- 0.3 ng/dl, SE). In hypothyroidism the serum concentrations were low or unmeasurable. As most of the hypothyroid subjects were elderly their serum T 2 concentrations overlapped with the low values found in the elderly euthyroid subjects. In classical hyperthyroidism serum T 2 concentrations were greatly increased (3.3 to 31 ng/dl (11.8 +- 2.7 ng/dl, SE) but in ''T 3 toxicosis'' the concentrations were only modestly increased

    Objective: To investigate the changes of serum BGP levels in different age-groups. Methods: Serum BGP levels were determined with RIA in 306 subjects of different age-groups. Results: The serum BGP levels were highest in subjects of the pre-adolescent group (age5-15, n=60, vs other groups, all P 50, n=80, P<0.001). Levels in the middle age group were the lowest and were significantly lower than those in the old age group (P<0.001). No sex related differences were observed in the pre-adolescent and middle age groups, but in the youth group, serum BGP levels were significantly higher in the males than those in the females (P<0.05). However, in the old age group, the reverse was true i.e. values being significantly higher in the females (vs males, P<0.01). Conclusion: Serum BGP levels varied greatly among the different age groups. (authors)

    Serum lipid levels were measured in 66 healthy sloth bears (Melursus ursinus ursinus) living under semicaptive conditions with access to natural food resources in the Bannerghatta Biological Park (Karnataka, India), a portion of their native habitat range in the Indian peninsula. Total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein cholesterol levels were analyzed. The effects of age, body weight, and season on these lipid parameters were statistically evaluated. There were no correlations between age and any of the serum lipid parameters analyzed. Positive correlations of body weight to both triglyceride and HDL cholesterol levels in these bears were identified. In addition, seasonal trends in physiological serum lipid values, potentially due to variations in the sloth bear diet, were identified. Serum triglyceride levels were higher during postmonsoon season and cholesterol levels were higher during winter compared to other seasons. Serum lipid values obtained from sloth bears in this study were also compared to previously published data on other members of the family Ursidae. This is the first report of serum lipid values as a reference for sloth bears. These values can be used as sensitive predictors of overall health and nutritional status to aid in the captive management and feeding of these bears.

    In this study, serum zinc and lipoprotein concentrations were determined in order to assess the health status of an elderly population residing in Sao Paulo city, SP, Brazil. This population consisted of elderly considered healthy and participating of a 'Successful Ageing' program of the Sao Paulo University Medical School. Fasting blood samples were collected from 87 elderly individuals (63 females and 24 males) aged 60-91 and mean age of 72 +- 7 years. Zn concentrations were determined by neutron activation analysis at the IPEN/CNEN/ SP and, the lipoprotein (HDL, LDL and total cholesterol) concentrations were determined using routine analysis methods of the Central Laboratory Division, Hospital das Clinicas, FMUSP. Results obtained for Zn indicated that all the individuals presented this element within the recommended value. For total cholesterol and HDL-cholesterol concentrations, 96 % of elderly presented levels within the desired range but for LDL cholesterol concentrations only about 70.0 % of individuals were in the desired range. Serum concentration of Zn were positively correlated to LDL-cholesterol levels (correlation coefficient r = 0.21, p < 0.06). Furthermore, the ratios of [HDL-cholesterol] / [LDL-cholesterol] were negatively correlated with Zn concentrations (r = - 0.234, p < 0.04). The positive correlation found between the serum concentrations of Zn and LDL-cholesterol indicates the possible effect of this element in serum lipoprotein profiles. Thus ,these findings suggest that more investigations should be conducted on Zn supplementation in elderly subjects with cardiovascular diseases. (author)

    Androgens and insulin may contribute to increased sebum production in the pathogenesis of acne vulgaris. We investigated the association between serum desnutrin levels and acne vulgaris in the pathogenesis of insulin resistance. 25 patients presenting with acne vulgaris and 25 control subjects participated in this study. Fasting blood glucose, triglycerides, LDL, VLDL, HDL, total cholesterol, insulin, C-peptide and thyroid function tests were measured. The homeostasis model assessment of insulin resistance (HOMA-IR) was used to calculate insulin resistance. Desnutrin levels were determined by enzyme-linked immunosorbent assay (ELISA) according to the manufacturer's protocol. Patients with acne vulgaris had a mean serum desnutrin level of (8.83 ± 1.13 μIU/mL), which was statistically significantly lower in the control group (10:58 ± 3.43 μIU/mL). In patients with acne vulgaris the serum glucose levels, insulin levels and HOMA-IR values (87.92 ± 7:46 mg/dL, 11.33 ± 5.93 μIU/mL, 2.49 ± 1.40, respectively) were significantly higher than the control group (77.36 ± 9.83 mg/dL, 5.82 ± 2.68 μIU/mL, 1.11 ± 0.51, respectively) (p = 0.01, pacne vulgaris, as a result of increased levels of serum glucose and insulin, the function of desnutrin was suppressed, perhaps contributing to insulin resistance.

    Serum prostate-specific antigen (PSA) is an important tumour, marker which is widely used to trigger trans-rectal ultrasound (TRUS)-guided prostate biopsy. However, the PSA levels vary with race and ethnicity. Therefore, there is a need to have an Indian reference range. All adult male patients meeting the inclusion and exclusion criteria were enrolled in this study. They were subjected to assessment of serum total PSA, digital rectal examination and trans-abdominal ultrasound. If any one or more of these were found abnormal, then a TRUS-guided 12-core prostate biopsy was done. Patients who were detected to have prostatic cancer were excluded from the final analysis. The data so obtained was grouped among the following three age groups: 40-49, 50-59 and 60-70 years, and the age-specific PSA values, prostatic volume and PSA density were found. A total of 1772 patients were analysed. The mean serum total PSA was 1.76 ng/ml with a standard deviation of 2.566 ng/ml. Group-wise age distribution of the mean serum total PSA was 1.22, 1.97 and 2.08 ng/ml in 40-49, 50-59 and 60-70 years age groups. The mean total PSA and the age-specific PSA range tend to be lower in the Indians than the Western population.

    Tuberculosis (TB) is one of the oldest infectious diseases in the world and still affects humanity today. Since 1993, the World Health Organization (WHO) considers TB as a global emergency. The clinical history of the individual, the serum exams and particularly, the imaging examination of the thorax, are used for diagnostic confirmation and monitoring of disease. TB is a chronic disease that usually evolves with pulmonary sequelae that must be monitored. The exam of the image more precise to assess the radiological patterns found in these patients is high-resolution computed tomography (HRCT), which aids in medical diagnosis and permit the determination of the area affected by radiological abnormalities of pulmonary tuberculosis. The best known of such modifications by means of exams or more accurate techniques is of extreme importance. Therefore, this study aimed to show the quantification, performed by algorithms, of the areas affected by the radiological abnormalities of TB through the HRCT, and compared with serum exams. We studied 16 patients with confirmed diagnosis of TB. The serum exams evaluated included: hemoglobin, hematocrit, albumin, speed hemo sedimentation and C-reactive protein. With the values of serum exams we observed that patients have anemia, low albumin levels and inflammatory activity, corroborating imaging exams, which show severe impairment of lung area due to the inflammation caused by disease activity.

    Background Endocan (endothelial cell-specific molecule-1) is a proteoglycan and plays an important role in angiogenesis and inflammation. The aim of this study was to evaluate of serum and urinary concentrations of endothelial cell-specific molecule-1 in bladder cancer. Methods The study included 50 bladder cancer patients, 50 with urinary tract infection and 51 healthy volunteers. Serum and urinary endothelial cell-specific molecule-1 concentrations were measured with enzyme linked immunosorbent assay. Results In bladder cancer group, serum and urinary endothelial cell-specific molecule-1 concentrations were significantly higher than in the healthy subjects ( P = 0.003 and P bladder cancer and urinary tract infection groups in terms of serum and urinary endothelial cell-specific molecule-1 concentrations. Urinary endothelial cell-specific molecule-1 concentrations were higher than those of corresponding serum endothelial cell-specific molecule-1 concentrations ( P bladder cancer and urinary tract infection groups, P = 0.002 for healthy subjects). In bladder cancer group, there was a positive correlation between serum endothelial cell-specific molecule-1 and urinary endothelial cell-specific molecule-1 concentrations ( r = 0.32, P = 0.002). For serum endothelial cell-specific molecule-1, sensitivity and specificity were 50%, and 77%, and for urinary endothelial cell-specific molecule-1, 62%, and 71%, respectively. Conclusion Serum and urinary endothelial cell-specific molecule-1 concentrations increase in bladder cancer. This parameter also increases in serum and urine of cases with urinary tract infection. That urinary endothelial cell-specific molecule-1 values were higher than serum endothelial cell-specific molecule-1 values in all groups may be attributed to direct exfoliation of epithelial cells in bladder to urine.

    Full Text Available The aim of this paper was to prove the relation between serum lipid values (cholesterol, trig- lyceride, low density cholesterol, high density cholesterol and primary open -angle glaucoma. The study includes two patient groups: 50 patients with primary open-angle glaucoma and 50 patients without this disease. However, all 100 patients were tested for serum lipid values. The research covered a period of six months (from May to December 2007.. Primary open-angle glaucoma was diagnosed with intraocular pressure values (between 20,1 and 25,6 mm Hg measured with Schiotz tonometry. The visual field changes were confirmed with Goldmann perimetry. The gonioscopies were done for diagnosis confirmation. The serum lipid values were confirmed with enzymatic colorimetry in vitro method. U-test (Mann-Witney-Wilcox test and t-test, as nonparametric tests, were used for statistical evaluations. The cholesterol mean value in the test group was 6,14 mol/dm1 (3,20-8,10 mol/dm3 whereas in the control group it was 5,96 mol/dm3 (2,70-8,80 mol/dm3. U-test was with negative ranks (z=-0,83 AS=0,678. The triglyceride mean value in the test group was 2,38 mol/dm3 (0,84-11,73 mol/m3 and in the control group it was 2,04 mol/dm3 (0,63-5,89 mol/dm3. U-test was with positive ranks (z=0,950 AS=0,342. High density cholesterol was average in the test group with 1,45 mol/dm3 (0,71-3,40 mol/dm3 and in the control group 1,40 mol/m3 (0,80-3,20 mol/dm3. Low density cholesterol in the test group was 3,98 mol/m3 (1,82-6,49 mol/m3 and in the control group 4,08 mol/m3 (2,69-5,69 mol/m3. These results had positive ranks according to U-test. Serum lipid values could be one of predictable factors in primary open-angle glaucoma diagnosis. Due to the patient age, cholesterol values, as common factors in primary open-angle glaucoma and atherosclerosis genesis, could be concern in the same aetiology based on dyslipidaemia as well.

    Polycystic ovary syndrome (PCOS) is an ovulatory disorder that affects 6-10% of women of reproductive age. Serum AMH level may be an additional factor, or surrogate of PCOM, in the diagnostic criteria of PCOS. We evaluated the correlations between the serum AMH level and various endocrine and metabolic features in PCOS using the latest fully automated assay. Serum AMH level was compared between 114 PCOS patient (PCOS group) and 95 normal menstrual cycle women (Control group). Correlations between serum AMH level and various endocrine and metabolic factors were analysed in PCOS group. The serum AMH level was significantly higher in the PCOS group (8.35±8.19 ng/mL) than in the Control group (4.99±3.23 ng/mL). The serum AMH level was independently affected by age and the presence of PCOS on multiple regression analysis. Ovarian volume per ovary (OPVO) showed the strongest positive correlation (r=0.62) with the serum AMH level among related factors. On receiver operating characteristic (ROC) curve analysis, the cut-off value of AMH for the diagnosis of PCOS was 7.33 ng/mL, but this value did not have high efficacy (sensitivity 44.7%, specificity 76.8%). A cut-off value of 10 ng/mL had a high specificity of 92.6%, although the sensitivity was low (24.6%). The serum AMH level was elevated and reflected ovarian size in PCOS patients. The serum AMH level could be a surrogate for ultrasound findings of the ovaries in PCOS and might be useful for estimating ovarian findings without transvaginal ultrasound in the diagnosis of PCOS.

    The serum concentrations of thyrotropin (TSH) were measured by means of radioimmunoassay, in 98 cases of normal controls, 51 cases of hyperthyroidism, 80 cases of primary hypothyroidism and 4 cases of secondary hypothyroidism to evaluate the diagnostic significance in various functional states of the thyroid. The obtained data were analyzed in correlation with other thyroid function test values in various phases of the functional thyroid diseases. The results were as follows: 1) The serum TSH concentration in normal control group was (1.3-8.0 μU/ml). 2) The measurement of serum TSH was more significant in diagnostic accuracy compared with that of serum T 4 (75.0±12.2%). Free T-4 Index (64.2±15.2%), serum T 3 (41.0±21.0%) or T 3 resin uptake (41.1±15.8%) in evaluation of primary hypothyroidism. 3) In case of overt hypothyroidism, the serum TSH and T 4 were both abnormal, compatible with the clinical diagnosis, while in case of preclinical or mild hypothyroidism, the serum T 4 (41.2±23.8% or 50.0±25.0%) was much less reliable than serum TSH. 4) In the treatment of primary hypothyroidism with desiccated thyroid, the administration of 1 grain of the hormone per day was sufficient to suppress the serum concentration of TSH to normal range. It showed that the measurement of serum TSH concentration was a significant criteria in evaluating the efficiency of the treatment of hypothyroidism. 5) The measurement of serum TSH concentration is a very significant method in the early detection of hypothyroidism induced during or after the treatment of the hyperthyroidism with antithyroid drugs or radioactive Iodine ( 131 I).

    Objective: To measure the zinc level in fertile and infertile population and to find out relationship of serum and seminal plasma zinc levels and serum testosterone in oligospermic and azoospermic infertile men. Design: Comparative study. Place and Duration of Study: The Infertility Clinic, Jinnah Postgraduate Medical Center (JPMC), Karachi, from January 2002-July 2003. Patients and Methods: Fifty-eight primary infertile male subjects, without any treatment, who had regular unprotected intercourse for at least 12 months without conception with their partners, aged 20-40 years, having normal and regular menstrual cycles without any uterine pathology or hormonal disturbance were selected from Infertile Clinic, Jinnah Postgraduate Medical Center, Karachi. After semen analyses, they were grouped as, oligospermic (30), and azoospermic (28). Twenty-five known fertile male selected from general population (their spouse had given birth to a child within one year) and after semen analysis were taken as normospermic control group. Semen analyzed according to WHO criteria and serum and seminal plasma zinc was estimated by 5Br. PAPS colorimetric method. Serum testosterone, LH, and FSH were measured by ELISA, using kits supplied by Diagnostic System Laboratories (DSL), U.S.A. Results: The mean value for testosterone was significantly low in oligospermic, (8.04+0.76) and azoospermic subjects (7.14+0.27) as compared to normospermic (9.90+0.14) control groups (p<0.05, p<0.001 respectively), serum LH (p<0.05, p<0.001) respectively) and FSH (p<0.05) were significantly higher than normospermic control group. Serum and seminal plasma zinc levels was low in oligospermic, and azoospermic subjects when compared with normospermic control groups (p<0.05, p<0.001 respectively). This suggests its involvement in spermatogenesis and infertility in such patients. Seminal zinc level has weak correlation with testosterone in oligospermic (r=0.44, p<0.05) and with serum zinc in azoospermic

    Serum lysozyme levels were determined on 670 consecutive subjects seen for regularly scheduled clinic examinations of the Adult Health Study in Hiroshima. Serum lysozyme levels were found to vary significantly with the absolute peripheral granulocyte count, age, sex, and month of study. A high level of correlation also was noted between serum lysozyme and diabetes mellitus. This was at least in part attributable to greater average age in patients with diabetes. Suggestive relationship was established between serum lysozyme levels, respiratory diseases, and tuberculosis. These changes are believed to reflect active inflammation with excessive destruction of granulocytes and parenchymal tissues in those patients with the more acute processes. No relationship was found between serum lysozyme and previous exposure to ionizing radiation. These studies indicate that the serum lysozyme level may be useful in the study of the kinetics of leukopoiesis, the aging process, and in the detection of subtle inflammatory processes. 21 references, 5 tables.

    1983-01-01

    A radioimmunoassay for serum ursodeoxycholic conjugates using an iodine-125 ligand has been developed. The bile acid was present in normal fasting serum (0.19 +- SD 0.19 μmol/l, n=24) and 2-hour post-prandial serum (0.8 +- SD 0.8 μmol/l, n=16). Gallstone patients undergoing oral ursodeoxycholic acid therapy had significantly higher post-prandial serum levels (21.5 +- SD 14.0 μmol/l, n=15) by radioimmunoassay. Gas liquid chromatography analysis indicated that in normal serum ursodeoxycholic acid was totally conjugated, whereas sera from gallstone patients contained a proportion as the free bile acid (10.2 +- SD 8.1 μmol/l, n=15). Following an oral dose of ursodeoxycholic acid, both unconjugated and conjugated forms of the bile acid appeared in the serum of healthy individuals. (Auth.)

    Objective: To explore the clinical value of determination of serum PRL levels inpost-menopausal women. Methods: Serum PRL levels were determined with RIA in 596 post-menopausal women (age 45-59, mean 55). Results: The normal range of serum PRL level in this laboratory was 0-30 ng/ml. Among the 596 women tested, 77(13%) had their PRL levels above 30 ng/ml. Further investigation with CT and/or MRI revealed presence of micro-pituitary-adenoma in 31 of the Symptoms of menopausal syndrome and osteoporosis were much more severe in women with hyperprolactinemia then in those without. Conclusion: As hyperprolactinemia might be a high risk factor for development of breast cancer, hormone replacement therapy (HRT) in menopausal women with hyperprolactinemia should be applied very cautiously, even withheld at all. Determination of serum prolactin levels in post-menopausal women is of practical clinical value. (authors)

    Weaving, Gary; Batstone, Gifford F; Jones, Richard G

    2016-01-01

    In the UK, a common reference interval for serum albumin is widely used irrespective of age or sex. Implicit in this is that laboratories produce analytically similar results. This paper challenges the validity of this approach. A three-week collection of results sent to all primary care centres in England has been analysed by age, sex and laboratory. In all, 1,079,193 serum albumin reports were included in this analysis. The mean population serum albumin concentration increases to peak at around age 20 years and then decreases with increasing age. Values in females decrease more rapidly but become close to male values at 60 years. The variation between laboratories was large and potentially clinically significant. Reference intervals for serum albumin should be stratified by age and sex. Until there is greater methodological standardization, laboratories should determine their own reference intervals and not accept a single consensus reference interval. © The Author(s) 2015.

    Monoclonal serum free light chain measurements are used to follow up and manage patients with monoclonal gammopathies, and abnormal serum free light chain ratios are associated with risk of progression in certain diseases. We aimed to validate the reference intervals in our population. Reference intervals for κ and λ free light chains were established on 120 healthy adults. Creatinine levels were measured to exclude renal dysfunction and serum protein electrophoresis was performed. All creatinine values were within normal limits. After exclusion of subjects with abnormal serum protein electrophoreses, 113 subjects were available for analysis. The 95% reference interval was 6.3-20.6 mg/L for κ free light chains, 8.7-25.9 mg/L for λ free light chains and 0.46-1.23 for free light chain ratio. Most of the values fell within the manufacturer's recommended limits and therefore could be used for our population.

    Objective. To examine alteration of serum interleukin-6 and its clinical significance in burning mouth syndrome (BMS) patients. Methods. 48 BMS patients and 31 healthy controls participated in the study. Serum interleukin-6 was measured by means of ELISA. Hamilton rating scale of depression (HRSD) and visual analogue scale (VAS) were used to quantitiate depressive status and pain levels of subjects, respectively. Results. 15 (31%) patients displayed substantial depressive symptoms (HRSD ≧ 16). HRSD scores of patients were significantly higher than controls and positively correlated to their VAS values (P = .002). Serum interleukin-6 in patients was much lower than controls and negatively correlated to their VAS values (P = .011). However, no significant relations were found between interleukin-6 and HRSD scores (P = .317). Conclusions. Serum interleukin-6 in patients with burning mouth syndrome is decreased and negatively correlated to chronic pain. Both psychological and neuropathic disorders might act as precipitating factors in BMS etiopathogenesis. PMID:17641729

  13. Use value, exchange value, and resource scarcity

    1999-01-01

    The literature on natural resource scarcity indicators is reviewed. Scarcity indicators can be classified by what is being measured: value of the resource stock or value of extracted resource commodities; whose value is considered: social vs. private scarcity; and by the mode of valuation considered: exchange value and use value. Prices and rents are common measures of exchange value or indicators of ''exchange scarcity'' and unit costs can be seen as use value indicators or indicators of u se scarcity . The major aim of this paper is to demonstrate the links between productivity indicators such as unit costs and the classical concept of use value. The two classes of indicator relate to John Commons' discussions of scarcity and efficiency, and a marginal vs. a non-marginal approach to value and scarcity. The classical use value concept also has wider relevance for issues of valuation in energy, resource, and environmental policy. (author)

    A 'Prolifigen TK-REA' kit for measuring serum thymidine kinase (TK) was fundamentally and clinically evaluated. Laboratory findings for recovery, dilution, and reproducibility were satisfactory. There was no correlation between serum TK activity and serum lactic dehydrogenase, carcinoembryonic antigen, or ..cap alpha..-fetoprotein. The serum concentration of TK in normal volunteers ranged from 1.6 to 6.5 U/L. It was extremely high for chronic myeloid leukemia (CML) and acute myeloid leukemia (AML), as compared to the normal value. In the AML group, higher incidence of blasts in peripheral blood tended to be associated with higher serum concentration of TK. A similar tendency was seen in the case of acute lymphocytic leukemia (ALL) and myelodysplasia syndrome (MDS). A positive correlation between serum TK activity and the absolute counts of myeloblasts in peripheral blood existed in CML and AML patients. Since patients with hematological neoplastic disorders, who have abnormality in DNA metabolism, tended to have higher serum TK activity than did normal volunteers, serum TK activity may have a potential marker for abnormal DNA metabolism.

    Full Text Available Studies of the changes in serum protein pattern in the neonatal period in animals are still limited. Therefore, the objective of this study was to evaluate the changes in the concentrations of serum protein fractions in 7 clinically healthy merino lambs (4 males, 3 females during their first month of life. The first blood sampling was performed before the colostrum intake and then at 1, 2, 7, 14 and 30 days of age. Blood serum was analysed for total serum protein concentrations and for the relative and absolute values of serum protein fractions - albumin, alpha1- (α1, alpha2- (α2, beta- (β, and gamma- (γ globulins. The results showed a significant effect of age on the serum total protein concentrations and for all the protein fractions. The concentrations of total proteins and γ-globulins increased significantly 1 day after the colostrum intake (P P 1-globulins significantly decreased during the first month of life (P 2- and β-globulins increased significantly from birth till the end of the monitored period (P < 0.001. Our results suggest that the serum protein electrophoretic pattern in growing lambs is significantly influenced by the age of the evaluated animal, and this should be taken into consideration when interpreting the serum protein profile. Our findings extend existing knowledge about significant changes in the protein profile associated with the physiological adaptation process in the neonatal period in young animals.

    In order to evaluate the clinical significances of the serum vitamin B 12 , folate and ferritin levels in patients with malignant tumors, the levels were measured in 10 normal control subjects, 70 patients with malignant tumors, 7 patients with liver cirrhosis and 25 patients with other benign diseases. The results are as follows: 1) In normal control subjects, mean serum values for vitamin B 12 , folate and ferritin level were 588.80±131.58 pg/ml, 5.59±1.52 ng/ml and 89.22±42.78 ng/ml retrospectively. 2) There was no significant difference in serum levels between patients with benign diseases and normal control subjects. 3) The serum vitamin B 12 and ferritin levels in patients with liver cirrhosis were significantly higher than in normal control, and the serum folate levels in these patients were lower than in normal control subjects. 4) The serum vitamin B 12 and ferritin levels in patients with malignant tumors were significantly higher than in normal control subjects, and the serum folate levels in these patients were significantly lower than in normal control subjects. The above results suggest that the serum vitamin B 12 and ferritin may be useful as tumor markers in patients with malignant tumors.

  17. Control of treatment of differentiated thyroid carcinoma by measurement of thyroglobulin in serum

    1978-01-01

    The presence of thyroglobulin in serum of patients with differentiated thyroid carcinoma was studied by a specific radioimmunoassay. Seventy-three patients with thyroid carcinomata were examined, 16 of whom had pulmonary or skeletal metastase, 11 local metastases, and the others no metastases. Patients with generalized metastases had very high serum thyroglobulin concentrations while those with local metastases had slightly elevated or normal concentrations. Those with remaining thyroid tissue had mainly normal thyroglobulin levels and patients with neither metastases nor remaining thyroid tissue had undetectable serum thyroglobulin. In seven patients with metastases it was possible to observe the development of serum thyroglobulin after 131 I treatment. In all cases the serum thyroglobulin concentration paralleled the development of the clinical status. Elevated serum thyroglobulin was also found in benign thyroid diseases such as hyperthyroidism and endemic goitre. Measurement of thyroglobulin in serum is therefore of little value in differentiating between benign and malignant thyroid diseases, but it is a good method for the follow-up control of patients with differentiated thyroid carcinomata. Because normal thyroglobulin levels do not exclude local metastases, additional examinations are necessary if normal thyroglobulin levels are found. When thyroglobulin is undetectable, metastases can be excluded and the measurement of thyroglobulin in serum can replace all other methods in the follow-up control. (author)

    One hundred twenty-seven Jersey cows (1 to 6 years of age) within a 160.93-km radius of Baton Rouge, La, were selected at random over a 3-year period to determine serum values for total creatine kinase, aspartate transaminase, calcium, phosphorus, alkaline phosphatase, cholesterol, total protein, globulin, urea nitrogen, and glucose. Breed and age were partitioned as possible sources of variation. Seasonal temperature and management influences were taken into account by restricting the sampling area. Seasonal temperature and management influences along with reproductive status and stage of lactation, were randomized by sampling over the 3-year period. All serum values, except aspartate transaminase, urea nitrogen, and glucose were influenced by age. Serum cholesterol, total protein, and glucose were influenced by age. serum cholesterol, total protein, and globulin tended to increase with age, whereas creatine kinase, calcium, phosphorus, and alkaline phosphatase generally decreased with age.

    Nisula, B.C.; Louvet, J.P.

    1978-01-01

    A method for concentrating human TSH (hTSH) from serum for use in RIAs is described. The method takes advantage of the affinity of the plant lectin, concanavalin A, for the carbohydrate portion of the hTSH molecule. The hTSH from 2.5 ml serum was adsorbed to concanavalin A covalently linked to sepharose and then radioimmunoassayed using the hTSH antiserum and hTSH for iodination distributed by the National Pituitary Agency. For the RIA standard curve, the hTSH reference preparation was concentrated from a serum wwith undetectable hTSH in order to correct for recovery and to control for nonspecific effects. The percentage of serum hTSH extracted from 2.5 ml serum with the concentration procedure was 76.6 +- 3.4% (mean +- SD). The coefficient of correlation between serum hTSH, determined with the concentration procedure, and serum hTSH determined without was 0.979 (P < 0.001). Over 95% of normal adult men and women had detectable levels of serum hTSH, ranging from < 0.56 to 4.0 μU/ml. The mean of detectable serum hTSH levels in normal adult women (n = 11) was 1.54 +- 1.03 μU/ml (mean +- SD) and in normal men (n = 9) was 2.02 +- 1.15 μU/ml (mean +- SD). Clinically hyperthyroid patients with diffuse and nodular toxic goiters (n = 8) and patients with hypothyroidism secondary to pituitary disease (n = 6), four of whom were taking replacement doses of thyroid hormone, had undetectable serum hTSH levels. Serum hTSH in patients with primary hypothyroidism uniformly exceeded the normal range. This hTSH concentrating procedure enhances the effective sensitivity and, therefore, the clinical utility of the RIA for hTSH in serum

    2015-12-01

    Full Text Available Off-line sample prefractionations applied prior to biomarker discovery proteomics are options to enable more protein identifications and detect low-abundance proteins. This work compared five commercial methods efficiency to raw serum analysis using label-free proteomics. The variability of the protein quantities determined for each process was similar to the unprefractionated serum. A 49% increase in protein identifications and 12.2% of reliable quantification were obtained. A 61 times lower limit of protein quantitation was reached compared to protein concentrations observed in raw serum. The concentrations of detected proteins were confronted to estimated reference values.

    Introduction: Measurement of serum cobalamin (Cbl) is routinely used to assess suspected Cbl deficiency. Surprisingly, 15% of all samples analysed for serum Cbl show values above the reference range of 200-600 pmol/L. Aim: We hypothesized that increased Cbl levels are caused by alterations...... in the circulating Cbl binding proteins haptocorrin (HC) and/or transcobalamin (TC), and that such changes may be of clinical importance. Materials and methods: We collected 834 blood samples from hospital treated patients with serum Cbl levels: 1000 pmol/L. In-house ELISAs were used...

    Conclusion: Although the positive CEA, CYFRA 21-1, NSE, and TSGF rates were observed at low values during the NSLCLC serum diagnosis, they still played an important role in diagnosing lung cancer. Significant levels of CEA, CYFRA 21-1, NSE, and TSGF were detected in the serum. The amounts found were useful for diagnosing NSCLC patients who depended on the currently limited biomarker development.

    Full Text Available A prospective study of lipid profile was done in 60 patients of vertigo at E.L.M.C. Lucknow from 2011 to 2014. All components of serum cholesterol were analyzed. Serum cholesterol and hyperlipidemia as an etiology of the atherosclerosis of all blood vessel s also have a role in vestibulo - cochlear vessels. It was found that there were 34 females and 26 males and maximum number of patients (63.33% in the age group of 31 - 50years. Appreciable difference (p<0.05 in the mean value of total lipid, total cholester ol, triglycerides and phospholipids in the control and study group was found but difference was not significant in the mean value of HDL, LDL and VLDL cholesterol level. Four cases of diabetes and ten cases of hypertension of 60 vertigo cases were having m arked vertigo of longer duration. These findings were similar to Mehra Y.N. Thus we find that serum lipid studies are important in the patients of vertigo for the diagnosis and management

    In drug invention and early disease prediction of lung cancer, metabolomic biomarker detection is very important. Mortality rate can be decreased, if cancer is predicted at the earlier stage. Recent diagnostic techniques for lung cancer are not prognosis diagnostic techniques. However, if we know the name of the metabolites, whose intensity levels are considerably changing between cancer subject and control subject, then it will be easy to early diagnosis the disease as well as to discover the drug. Therefore, in this paper we have identified the influential plasma and serum blood sample metabolites for lung cancer and also identified the biomarkers that will be helpful for early disease prediction as well as for drug invention. To identify the influential metabolites, we considered a parametric and a nonparametric test namely student׳s t-test as parametric and Kruskal-Wallis test as non-parametric test. We also categorized the up-regulated and down-regulated metabolites by the heatmap plot and identified the biomarkers by support vector machine (SVM) classifier and pathway analysis. From our analysis, we got 27 influential (p-value<0.05) metabolites from plasma sample and 13 influential (p-value<0.05) metabolites from serum sample. According to the importance plot through SVM classifier, pathway analysis and correlation network analysis, we declared 4 metabolites (taurine, aspertic acid, glutamine and pyruvic acid) as plasma biomarker and 3 metabolites (aspartic acid, taurine and inosine) as serum biomarker.

    Systemic inflammatory response syndrome (SIRS) and sepsis can be challenging to diagnose in cats. Retrospectively, we investigated the diagnostic and prognostic potential of serum amyloid A (SAA), a major feline acute-phase protein (APP), in a population of critically ill cats with SIRS related to trauma or sepsis. A total of 56 SIRS cats (trauma n = 27; sepsis n = 29) were included and compared with healthy controls ( n = 18). SAA concentration was significantly increased in SIRS cats compared to controls, confirming its potential for the detection of systemic inflammation in this species. Significantly higher values of SAA were detected in cats belonging to the sepsis group; however, according to the results of the receiver operating characteristic curve analysis, the value of using SAA (>81 mg/L) to discriminate septic cats was only moderate (AUC = 0.76). Additionally, cats with sepsis had significantly higher serum bilirubin concentrations and toxic neutrophil changes compared to the trauma group. Overall, 38 of 56 cats were survivors; 18 of 56 were non-survivors, with 83% of the non-survivors (15 of 18) belonging to the sepsis group. Serum bilirubin concentration, but not SAA, was able to predict outcome. Prospective studies are needed to assess the potential of SAA in the diagnosis of feline sepsis and outcome prediction.

    A portable analytical chemistry analyzer was used to make field assessments of wild harlequin ducks (Histrionicus histrionicus) in association with telemetry studies of winter survival in Prince William Sound, Alaska. We compared serum chemistry results obtained on-site with results from a traditional laboratory. Particular attention was paid to serum glucose and potassium concentrations as potential indicators of high-risk surgical candidates based on evaluation of the field data. The median differential for glucose values ( = 8 2) between methods was 0.6 mmol/L (quartiles 0.3 and 0.9 mmol/L) with the median value higher when assayed on site. Analysis of potassium on site returned a median of 2.7 mmol/L ( = 8 8 ; quartiles 2.4 and 3.0 mmol/L). Serum potassium values were too low for quantitation by the traditional laboratory. Changes in several serum chemistry values following a three-day storm during the study support the value of on site evaluation of serum potassium to identify presurgical patients with increased anesthetic risk.

    Obesity is increasing in developed as well as in developing countries. This analytical cross sectional study was carried out to document the relation between blood pressure, serum creatinine and body mass index in female and to assess potential health differences among obese female and normal weight female. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2012 to June 2013. Seventy female persons volunteered as subjects. Among them 35 were within normal weight (BMI 18.5-24.9kg/m²) and 35 were obese (BMI≥30kg/m²). Non probability purposive type of sampling technique was used to select the subjects. Measurement of body mass index and blood pressure were done as per procedure. Serum creatinine level was estimated by enzymatic colorimetric method. The results were calculated and analyzed by using SPSS (statistical package for social science, version 17.0), scientific electronic calculator and simultaneously with a computer assisted program like Microsoft excel. Unpaired 't' test was applied to find the significance of difference regarding serum creatinine and blood pressure levels in obese female. The value of p was 1% to indicate highly significant and 5% to indicate simply significant or statistically significant. The mean±SE of systolic blood pressure, diastolic blood pressure and serum creatinine levels were 135.71±1.58mmHg, 88.74±0.95mmHg and 1.03±0.01mg/dl respectively; significant at 1% level for obese group of BMI (phigh BMI is significantly related to increased levels of serum creatinine & blood pressure in obese female which indicate the obese subjects are prone to cardiovascular & metabolic risk.

    The aim of the present study was to investigate the association between coffee consumption and serum lipid levels in a study population of 122 Turkish subjects (mean age, 41.4±12.69 years), including 48 males and 74 females. A questionnaire was compiled to determine baseline characteristics, and food and coffee consumption. Subjects were divided into three groups, which included non-drinkers, Turkish coffee and instant coffee drinkers, and anthropometric measurements were acquired, including weight, height and body mass index. Serum lipid levels were analyzed, including the total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very low-density lipoprotein cholesterol (VLDL-C) levels. Of the population studied, 76.2% had consumed at least one cup of coffee per week over the previous year. Daily consumption values were 62.3±40.60 ml (0.7±0.50 cup) for Turkish coffee and 116.3±121.96 ml (0.7±0.81 cup) for instant coffee. No statistically significant differences were observed in the serum levels of TC, TG, LDL-C, HDL-C or VLDL-C among the three groups. In addition, no statistically significant differences were observed in the serum lipid levels when comparing individuals who consumed coffee with sugar/cream or who smoked and those who did not (P>0.05). Therefore, the present observations indicated no significant association between the consumption of Turkish or instant coffee and serum lipid levels.

    Biomarker testing can be helpful to monitor disease progression after resection of pancreatic cancer. This systematic review aims to give an overview of the literature on the diagnostic value of serum tumor markers for the detection of recurrent pancreatic cancer during follow-up. A systematic search was performed to 2 October 2017. All studies reporting on the diagnostic value of postoperatively measured serum biomarkers for the detection of pancreatic cancer recurrence were included. Data on diagnostic accuracy of tumor markers were extracted. Forest plots and pooled values of sensitivity and specificity were calculated. Four articles described test results of CA 19-9. A pooled sensitivity and specificity of respectively 0.73 (95% CI 0.66-0.80) and 0.83 (95% CI 0.73-0.91) were calculated. One article reported on CEA, showing a sensitivity of 50% and specificity of 65%. No other serum tumor markers were discussed for surveillance purposes in the current literature. Although testing of serum CA 19-9 has considerable limitations, CA 19-9 remains the most used serum tumor marker for surveillance after surgical resection of pancreatic cancer. Further studies are needed to assess the role of serum tumor marker
