    Full Text Available Aim: Procalcitonin (PCT as a diagnostic marker for bacteremia and sepsis has been extensively studied. We aimed to study PCT levels in Salmonella infections whether they would serve as marker for early diagnosis in endemic areas to start empiric treatment while awaiting blood culture report. Materials and Methods: BACTEC blood culture was used to isolate Salmonella in suspected enteric fever patients. Serum PCT levels were estimated before starting treatment. Results: In 60 proven enteric fever patients, median value of serum PCT levels was 0.22 ng/ml, values ranging between 0.05 and 4 ng/ml. 95% of patients had near normal or mild increase (<0.5 ng/ml, only 5% of patients showed elevated levels. Notably, high PCT levels were found only in severe sepsis. Conclusion: PCT levels in Salmonella infections are near normal or minimally increased which differentiates it from other systemic Gram-negative infections. PCT cannot be used as a specific diagnostic marker of typhoid.

    Full Text Available Abstract Background Sepsis and complications to sepsis are major causes of mortality in critically ill patients. Rapid treatment of sepsis is of crucial importance for survival of patients. The infectious status of the critically ill patient is often difficult to assess because symptoms cannot be expressed and signs may present atypically. The established biological markers of inflammation (leucocytes, C-reactive protein may often be influenced by other parameters than infection, and may be unacceptably slowly released after progression of an infection. At the same time, lack of a relevant antimicrobial therapy in an early course of infection may be fatal for the patient. Specific and rapid markers of bacterial infection have been sought for use in these patients. Methods Multi-centre randomized controlled interventional trial. Powered for superiority and non-inferiority on all measured end points. Complies with, "Good Clinical Practice" (ICH-GCP Guideline (CPMP/ICH/135/95, Directive 2001/20/EC. Inclusion: 1 Age ≥ 18 years of age, 2 Admitted to the participating intensive care units, 3 Signed written informed consent. Exclusion: 1 Known hyper-bilirubinaemia. or hypertriglyceridaemia, 2 Likely that safety is compromised by blood sampling, 3 Pregnant or breast feeding. Computerized Randomisation: Two arms (1:1, n = 500 per arm: Arm 1: standard of care. Arm 2: standard of care and Procalcitonin guided diagnostics and treatment of infection. Primary Trial Objective: To address whether daily Procalcitonin measurements and immediate diagnostic and therapeutic response on day-to-day changes in procalcitonin can reduce the mortality of critically ill patients. Discussion For the first time ever, a mortality-endpoint, large scale randomized controlled trial with a biomarker-guided strategy compared to the best standard of care, is conducted in an Intensive care setting. Results will, with a high statistical power answer the question: Can the survival

    Full Text Available Background/Aims: The prognostic role of serum procalcitonin level in critically ill patients with ventilator-associated pneumonia was unclear. The aim of our study was to investigate the relationship between serum procalcitonin level and mortality risk in critically ill patients with ventilator-associated pneumonia. Methods: Data of critically ill patients with ventilator-associated pneumonia were retrospectively collected. Demographics, comorbidities, and serum procalcitonin level were extracted from electronic medical records. The primary outcome was mortality within two months after diagnosis. Multivariable Cox regression analyses were performed to assess the prognostic role of serum procalcitonin level in those patients. Results: A total of 115 critically ill patients with ventilator-associated pneumonia were enrolled in our study. Serum procalcitonin level was not associated with age, gender, or other comorbidities. Univariate Cox regression model showed that high serum procalcitonin level was associated increased risk of morality within 2 months after diagnosis (OR = 2.32, 95% CI 1.25-4.31, P = 0.008. Multivariable Cox regression model showed that high serum procalcitonin level was independently associated increased risk of morality within 2 months after diagnosis (OR = 2.38, 95% CI 1.26-4.50, P = 0.008. Conclusion: High serum procalcitonin level is an independent prognostic biomarker of mortality risk in critically ill patients with ventilator-associated pneumonia, and it's a promising biomarker of prognosis in critically ill patients.

    Full Text Available Background. Procalcitonin (PCT is a useful surrogate marker for the differentiation of postoperative infection and unspecific inflammatory reaction after surgery. It is known that postoperative course of the PCT serum level varies with type of surgery. No data exists about the postoperative course of serum PCT levels after primary total hip replacement (THR. Purpose. To characterize early postoperative serum PCT levels in uneventful primary THR compared to postoperative levels of different frequently used inflammatory blood parameters. Method. We prospectively investigated 31 patients. Blood samples were taken preoperatively and for 5 days postoperatively. PCT levels were compared with C-reactive protein (CRP, interleukin-6 (IL-6, and blood leucocyte counts (WBC. Results. In uneventful THR PCT levels showed a uniform low-level course with a peak at the second postoperative day. At the fifth day values returned to almost preoperative levels. On contrary, CRP levels remained high during the entire observational period. Only IL-6 levels showed a peak at postoperative day one with a quick and uniform return to preoperative levels. Conclusion. Similar to observations in cardiothoracic, intestinal, and neural surgeries, postoperative course of PCT after primary THR showed a uniform low-level course with a peak at the second postoperative day but below expected levels in systemic infections.

    Full Text Available OBJECTIVE: Clostridium difficile infection (CDI is a major cause of morbidity and biomarkers that predict severity of illness are needed. Procalcitonin (PCT, a serum biomarker with specificity for bacterial infections, has been little studied in CDI. We hypothesized that PCT associated with CDI severity. DESIGN: Serum PCT levels were measured for 69 cases of CDI. Chart review was performed to evaluate the presence of severity markers and concurrent acute bacterial infection (CABI. We defined the binary variables clinical score as having fever (T >38°C, acute organ dysfunction (AOD, and/or WBC >15,000 cells/mm(3 and expanded score, which included the clinical score plus the following: ICU admission, no response to therapy, colectomy, and/or death. RESULTS: In univariate analysis log10 PCT associated with clinical score (OR 3.13, 95% CI 1.69-5.81, P0.2 ng/mL was 81% sensitive/73% specific for a positive clinical score and had a negative predictive value of 90%. CONCLUSION: An elevated PCT level associated with the presence of CDI severity markers and CDI was unlikely to be severe with a serum PCT level below 0.2 ng/mL. The extent to which PCT changes during CDI therapy or predicts recurrent CDI remains to be quantified.

    Full Text Available "nBackground: Sepsis is one of the most important causes of mortality in severely ill ICU patients. At least, a part of high mortality rate in sepsis patients is due to less specific clinical symptoms for prompt diagnosis. Recently some studies report that serum levels of procalcitonin will increase in these patients but changes of serum levels following treatments is not known. This study was designed to determin procalcitonin levels in patients with bacterial infectious disease in ICU, initially and during therapy and compare the levels during response to treatment. "n"nMethods: This prospective cross-sectional study was conducted on ICU patients with infectious diseases, blood specimen collected on day 1 and then in days 3 and 7 of ICU admission. The semi-quantitative PCT-Q test was performed. "n"nResults: Thirty five patients, 22(62.9 % men and 13(37.1% women, were enrolled in this study. 18(51.4% patients died. Procalcitonin level in most patients in admission day was more than 10 ng/ml [16 (45.7%] but in patients that react to treatment, decline to lower than 0.5 ng/ml [14(77.8%]. Mean rank of procalcitonin level from 1.14 ng/ml in first day reached to 2.72 ng/ml in seventh day (p<0.0001. "n"nConclusions: This study showed that serum procalcitonin levels in ICU patients with bacterial sepsis significantly decrease following response to treatment. The measurement of serum procalcitonin in ICU patients with bacterial infectious diseases at first arrival day and following treatment is recommended.

    Full Text Available Objectives. To compare the value of procalcitonin, C-reactive protein (CRP and neopterin as indicators of immune deficiency, co-infection, efficacy of treatment, and disease progression, in patients with advanced HIV-1 infection. Design. Cross-sectional, investigating baseline blood measurements and clinical observations in 82 HIV-positive patients divided into an antiretroviral treatment (ART group and an ART-naïve group. Setting. Secondary general hospital in Pretoria. Results. Procalcitonin and CRP levels showed no significant differences between the ART and ART-naïve groups, and no correlations with CD4 counts or viral loads. CRP levels were significantly higher with TB co-infection (p<0.05. Neopterin levels were raised above normal in 92% of the ART-naïve group and in 75% of the ART group. The levels were significantly higher (p<0.05 in the ART- naïve group. Negative correlations were found between neopterin and CD4 counts for the total patient group (r=-0.482; p<0.001. Neopterin was significantly (p<0.05 higher in the HIV/TB co-infection group than in those without TB. Higher neopterin levels at baseline were associated with a decline in CD4 counts over the ensuing 6-month period, and patients with higher baseline neopterin levels developed more complications over the 6-month period. Conclusions. Compared with procalcitonin and CRP, neopterin appears to be associated with the degree of immunodeficiency and of co-infection with TB. Neopterin levels may be investigated further as a measure of disease progression or treatment response. S Afr J HIV Med 2012;13(2:78-82.

    Infection and septic complications in burn patients can be monitored by procalcitonin (PCT) and neopterin plasma values. The aim of the study was to investigate serum neopterin and PCT levels with WBC (white blood cell) and CRP (C-reactive protein) levels in patient group (PG) and healthy control group (HCG) and to investigate the relationship of these markers with burn wound infections (BWI). As the PG, 23 patients between 0-12 ages and up to 30% Total Body Surface Area (TBSA) burned and 15 HCG were included. PCT, neopterin, WBC, and CRP results on the first, the seventh, the fourteenth and the 21st day have been compared. During the follow-up period, 11 patients with BWI and 12 patients without BWI were classified as infected and non-infected patients, respectively. PCT and neopterin levels were detected higher in patients with BWI but no significant difference were present. Also, PCT and neopterin levels within the first 24 hours following the burn were detected higher in PG than HCG. CRP and WBC levels were detected high due to burn trauma. PCT and neopterin levels were increased in patients with BWI. PCT levels were increased during the pre-infectious period, while neopterin levels increased during the post-infectious period.

    Full Text Available Background: Recommendations have been made, following the multicenter Surviving Sepsis Campaign study, to standardize the definition of severe sepsis with reference to several parameters such as haemodynamic stability, acid-base balance, bilirubin, creatinine, International Normalized Ratio (INR, urine output and pulmonary functional value of the ratio between arterial oxigen partial pressure and inspiratory oxigen concentration. Procalcitonin (PCT is considered to be a gold standard biomarker for the inflammatory response, and recent studies have shown that it may help to discover whether a seriously ill person is developing sepsis. C-reactive protein (CRP is also used as a marker of inflammation in the body, as its blood levels increase if there is any inflammation in the body. The aim of this study was to evaluate serum procalcitonin and C-reactive protein levels as diagnostic and prognostic biomarkers of severe sepsis.

    Background Antibiotics are recommended for severe acute exacerbation of chronic obstructive pulmonary disease (AECOPD) admitted to intensive care units (ICU). Serum procalcitonin (PCT) could be a useful tool for selecting patients with a lower probability of developing bacterial infection, but its measurement has not been investigated in this population. Methods We conducted a single center prospective cohort study in consecutive COPD patients admitted to the ICU for AECOPD between September 2005 and September 2006. Sputum samples or tracheal aspirates were tested for the presence of bacteria and viruses. PCT levels were measured at the time of admittance, six hours, and 24 hours using a sensitive immunoassay. Results Thirty nine AECOPD patients were included, 31 of which (79%) required a ventilator support at admission. The median [25%–75% interquartile range] PCT level, assessed in 35/39 patients, was: 0.096 μg/L [IQR, 0.065 to 0.178] at the time of admission, 0.113 μg/L [IQR, 0.074 to 0.548] at six hours, and 0.137 μg/L [IQR, 0.088 to 0.252] at 24 hours. The highest PCT (PCTmax) levels were less than 0.1 μg/L in 14/35 (40%) patients and more than 0.25 μg/L in 10/35 (29%) patients, suggesting low and high probability of bacterial infection, respectively. Five species of bacteria and nine species of viruses were detected in 12/39 (31%) patients. Among the four patients positive for Pseudomonas aeruginosa, one had a PCTmax less than 0.25 μg/L and three had a PCTmax less than 0.1 μg/L. The one patient positive for Haemophilus influenzae had a PCTmax more than 0.25 μg/L. The presence or absence of viruses did not influence PCT at time of admission (0.068 vs 0.098 μg/L respectively, P = 0.80). Conclusion The likelihood of bacterial infection is low among COPD patients admitted to ICU for AECOPD (40% with PCT procalcitonin-based therapeutic strategy in critically ill COPD patients.

    Introduction To date, a specific marker to evaluate and predict the clinical course or complication of the liver-transplanted patient is not available in clinical practice. Increased procalcitonin (PCT) levels have been found in infectious inflammation; poor organ perfusion and high PCT levels in the cardiac donor appeared to predict early graft failure. We evaluated PCT as a predictor of early graft dysfunction and postoperative complications. Methods PCT serum concentrations were measured in samples collected before organ retrieval from 67 consecutive brain-dead donors and in corresponding recipients from day 0, before liver transplantation, up to day 7 after liver transplantation. The following parameters were recorded in donors: amount of vasopressive drug doses, cardiac arrest history 24 hours before retrieval, number of days in the intensive care unit, age of donor, and infection in donor, and the following parameters were recorded in recipients: cold and warm ischemia time, veno-venous bypass, transfusion amount during orthotopic liver transplantation (OLT), and occurrence of postoperative complication or hepatic dysfunction. Results In the donor, the preoperative level of PCT was associated with cardiac arrest and high doses of catecholamines before organ retrieval. In the recipient, elevated PCT levels were observed early after OLT, with a peak at day 1 or 2 after OLT, then a decrease until day 7. A postoperative peak of PCT levels was associated neither with preoperative PCT levels in the donor or the recipients nor with hepatic post-OLT dysfunction or other postoperative complications, but with two donor parameters: infection and cardiac arrest. Conclusion PCT level in the donor and early PCT peak in the recipient are not predictive of post-OLT hepatic dysfunction or other complications. Cardiac arrest and infection in the donor, but not PCT level in the donor, are associated with high post-OLT PCT levels in the recipient. PMID:18601732

    Full Text Available Abstract Background Both C reactive protein (CRP and procalcitonin (PCT are well known acute phase reactant proteins. CRP was reported to increase in metabolic syndrome and type-2 diabetes. Similarly altered level of serum PCT was found in chronic liver diseases and cirrhosis. The liver is considered the main source of CRP and a source of PCT, however, the serum PCT and CRP levels in non-alcoholic fatty liver disease (NAFLD were not compared previously. Therefore we aimed to study the diagnostic and discriminative role of serum PCT and CRP in NAFLD. Methods Fifty NAFLD cases and 50 healthy controls were included to the study. Liver function tests were measured, body mass index was calculated, and insulin resistance was determined by using a homeostasis model assessment (HOMA-IR. Ultrasound evaluation was performed for each subject. Serum CRP was measured with nephalometric method. Serum PCT was measured with Kryptor based system. Results Serum PCT levels were similar in steatohepatitis (n 20 and simple steatosis (n 27 patients, and were not different than the control group (0.06 ± 0.01, 0.04 ± 0.01 versus 0.06 ± 0.01 ng/ml respectively. Serum CRP levels were significantly higher in simple steatosis, and steatohepatitis groups compared to healthy controls (7.5 ± 1.6 and 5.2 ± 2.5 versus 2.9 ± 0.5 mg/dl respectively p Conclusion Serum PCT was within normal ranges in patients with simple steatosis or steatohepatitis and has no diagnostic value. Serum CRP level was increased in NAFLD compared to controls. CRP can be used as an additional marker for diagnosis of NAFLD but it has no value in discrimination of steatohepatitis from simple steatosis.

    Full Text Available To study the serum Procalcitonin (PCT level in inflammatory arthritis including gouty arthritis (GA, Rheumatoid arthritis (RA, and ankylosing spondylitis (AS without any evidence of infection were evaluated the possible discriminative role of PCT in gouty arthritis susceptibility in southern Chinese Han Population.From Feb, 2012 to Feb, 2015, 51 patients with GA, 37 patients with RA, 41 patients with AS and 33 healthy control were enrolled in this study with no evidence of infections. The serum level of PCT (normal range < 0.05 ng/ml was measured by electrochemiluminescence immunoassay (ECLIA. Disease activity was determined by scores of VAS (4.07 ± 1.15, DAS28 (4.97 ± 1.12, and ASDAS (2.97 ± 0.81 in GA, RA and AS groups respectively. Other laboratory parameters such as, serum creatinine (CRE, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP, uric acid (UA and white blood cells (WBC were extracted from medical record system.Serum PCT level was predominantly higher in gouty arthritis than in RA and AS patients, especially in the GA patients with tophi. PCT was significantly positively correlated with VAS, CRP and ESR in gouty arthritis and CRP in AS. PCT also had positive correlation-ship with ESR, DAS28 and ASDAS in RA and AS patients respectively, but significant differences were not observed.These data suggested that PCT is not solely a biomarker for infection, but also an indicator in inflammatory arthritis, especially in gouty arthritis.

    Inflammation is thought to play an important role in the pathogenesis of Bell's palsy (BP). Procalcitonin (PCT) is currently among the most frequently used proinflammatory biomarkers in clinical practice. In this study, we assessed the serum PCT levels for predicting the severity and prognosis of BP. In total, 32 patients with House-Brackmann (HB) grade II and III BP (low-grade group), 22 patients with HB grade IV and V (high-grade group) and 35 healthy individuals (control group) were included in this prospective study. PCT levels were compared among these three groups at the time of diagnosis. All patients received standard prednisolone and acyclovir treatment. The correlation between PCT levels and recovery was analyzed 3 months after treatment. The PCT levels for control, low-grade and high-grade BP groups were 0.01 ± 0.001, 0.35 ± 0.05, and 0.98 ± 0.41 ng/mL, respectively. The PCT level in low-grade group was significantly higher than that in control group (p < 0.001), and the PCT level in high-grade BP group was significantly higher than that in low-grade group (p = 0.01, p < 0.05). The complete recovery rate was 93.7 % in low-grade and 54.5 % in high-grade BP group (p = 0.015, p < 0.05). There was a strong negative correlation between PCT levels and recovery rates (r = -0.896, p < 0.001). PCT levels were significantly associated with the severity of BP and higher PCT levels were related with poor clinical outcome in terms of recovery. These results support the diagnostic and prognostic significance of PCT in patients with early BP. PMID:26894418

    Full Text Available BackgroundNumerous studies have shown that procalcitonin (PCT was not related to degree of trauma. High PCT serum levels have been found in patients with bacterial or fungal infection and also in acute phase of trauma. Currently, there has been no research discussed about changes in serum levels of PCT in particular head injuries and severe head injuries. Moderate and severe head injuries were common trauma cases in Emergency Room (ER and had high mortality rate. Based on Glasgow Coma Scale (GCS, moderate and severe head injuries were scored between 3 and 13. This research aim to determine whether high blood levels PCT can be used as a predictor of the occurrence of SIRS. Method: A cohort prospective study was applied in this research to determine high blood levels of PCT as a predictor for SIRS in moderate and severe head injury. This study was conducted from June 2013 - August 2013 at Sanglah General Hospital with 40 research subjects. Data was presented in tables and analyzed with Chi Square test at 95% CI and p <0.05% was considered significant. Results: From the 40 samples, there were 34 males (85% and 6 females (15%, 18 samples (45% had moderate head injury and 22 samples (65% had severe head injury. One sample (2.5 % was 0-10 years old, 15 samples (37.5% were 10-20 years old, 13 samples (32.5% were 20-40 years old, 7 samples (17.5% were 40-60 years old and 4 samples (10% were>60 years old. PCT levels in the blood obtained on day first were normal in 6 samples (15% and elevated in 34 samples (85%, SIRS (+ were found in 35 samples (87.5% and 5 samples (12.5% were SIRS (-. Using bivariate analysis between PCT levels and SIRS showed p = 0.000 (p < 0.05, and multivariate analysis of the control variables showed no significant correlation between variables with PCT levels. Conclusion: From 40 samples moderate head injury and severe head injury, there were 34 samples (85% with elevated PCT level on the first day, while 35 samples (87.5% had SIRS

    Full Text Available BACKGROUND: Acute kidney injury (AKI has been proposed as a leading cause of mortality for acute pancreatitis (AP patients admitted to the intensive care unit (ICU. This study investigated the predictive value of procalcitonin (PCT for AKI development and relevant prognosis in patients with AP, and compared PCT's predictive power with that of other inflammation-related variables. METHODS: Between January 2011 and March 2013, we enrolled 305 cases with acute pancreatitis admitted to ICU. Serum levels of PCT, serum amyloid A (SAA, interleukin-6 (IL-6, and C reactive protein (CRP were determined on admission. Serum PCT was tested in patients who developed AKI on the day of AKI occurrence and on either day 28 after occurrence (for survivors or on the day of death (for those who died within 28 days. RESULTS: Serum PCT levels were 100-fold higher in the AKI group than in the non-AKI group on the day of ICU admission (p<0.05. The area under the receiver-operating characteristic (ROC curve of PCT for predicting AKI was 0.986, which was superior to SAA, CRP, and IL-6 (p<0.05. ROC analysis revealed all variables tested had lower predictive performance for AKI prognosis. The average serum PCT level on day 28 (2.67 (0.89, 7.99 ng/ml was significantly (p<0.0001 lower than on the day of AKI occurrence (43.71 (19.24,65.69 ng/ml in survivors, but the serum PCT level on death (63.73 (34.22,94.30 ng/ml was higher than on the day of AKI occurrence (37.55 (18.70,74.12 ng/ml in non-survivors, although there was no significant difference between the two days in the latter group (p = 0.1365. CONCLUSION: Serum PCT is superior to CRP, IL-6, and SAA for predicting the development of AKI in patients with AP, and also can be used for dynamic evaluation of AKI prognosis.

    Full Text Available Abstract Background Antibiotics are recommended for severe acute exacerbation of chronic obstructive pulmonary disease (AECOPD admitted to intensive care units (ICU. Serum procalcitonin (PCT could be a useful tool for selecting patients with a lower probability of developing bacterial infection, but its measurement has not been investigated in this population. Methods We conducted a single center prospective cohort study in consecutive COPD patients admitted to the ICU for AECOPD between September 2005 and September 2006. Sputum samples or tracheal aspirates were tested for the presence of bacteria and viruses. PCT levels were measured at the time of admittance, six hours, and 24 hours using a sensitive immunoassay. Results Thirty nine AECOPD patients were included, 31 of which (79% required a ventilator support at admission. The median [25%–75% interquartile range] PCT level, assessed in 35/39 patients, was: 0.096 μg/L [IQR, 0.065 to 0.178] at the time of admission, 0.113 μg/L [IQR, 0.074 to 0.548] at six hours, and 0.137 μg/L [IQR, 0.088 to 0.252] at 24 hours. The highest PCT (PCTmax levels were less than 0.1 μg/L in 14/35 (40% patients and more than 0.25 μg/L in 10/35 (29% patients, suggesting low and high probability of bacterial infection, respectively. Five species of bacteria and nine species of viruses were detected in 12/39 (31% patients.

    Two diagnostic bundles were compared in 127 evaluable patients admitted with community-acquired pneumonia (CAP). Diagnostic modalities in all patients included cultures of sputum (if obtainable) and blood, urine for detection of the antigens of Streptococcus pneumoniae and Legionella pneumophila, and nasal swabs for PCR probes for S. pneumoniae and Staphylococcus aureus. At least one procalcitonin level was measured in all patients. For virus detection, patients were randomized to either a 5-virus, lab-generated PCR panel or the broader and faster FilmArray PCR panel. Overall, an etiologic diagnosis was established in 71% of the patients. A respiratory virus was detected in 39%. The potential for improved antibiotic stewardship was evident in 25 patients with only detectable respiratory virus and normal levels of PCT. PMID:27377675

    Full Text Available Koichi Sugimoto, Shogo Adomi, Hiroyuki Koike, Atsunobu Esa Department of Urology, NTT West Osaka Hospital, Osaka, Japan Background: Procalcitonin has been advocated as a marker of bacterial infection, so this study was carried out to determine the usefulness of serum procalcitonin in the early diagnosis of urosepsis. Methods: The subjects were 37 febrile patients with urinary tract infection in whom we examined the serum procalcitonin concentration at the start of treatment. Results: Thirty patients had acute pyelonephritis (16 simple, 14 complex, one had emphysematous pyelonephritis, five had acute prostatitis, and one had acute epididymitis. The procalcitonin level was <0.5 ng/mL in 18 patients, ≥0.5 ng/mL in one patient, ≥2 ng/mL in seven patients, and ≥10 ng/mL in 11 patients. Five of the 11 patients with procalcitonin levels ≥ 10 ng/mL had disseminated intravascular coagulation. All patients with urinary tract obstruction and disseminated intravascular coagulation had procalcitonin levels ≥ 10 ng/mL. Conclusion: Although this retrospective study comprised a small number of patients, we found that procalcitonin was a useful marker for urinary tract infection.

    This clinical case presentation describes the disease trajectory in two patients who presented with psychiatric symptoms as a result of abnormal serum glucocorticoid levels. One case involves a 58-year-old man with hypercortisolism, the other case concerns a 55-year-old woman with hypocortisolism. In both cases there was a considerable diagnostic delay in recognizing the underlying adrenal gland pathology. Abnormal glucocorticoid levels, caused by endocrine disorders, often results in psychiatric symptoms. Delay in diagnosis may have adverse consequences. Hyper- or hypocortisolism should be considered in patients who present with an atypical presentation of psychiatric symptoms. Moreover, the absence of specific physical signs or symptoms at first presentation in such patients does not exclude an underlying endocrinological cause. Therefore, physical and psychiatric reassessment of such patients should be considered at regular intervals. PMID:27507414

    Full Text Available Background/Aims: Puumala virus causes nephropathia epidemica (NE, a milder form of hemorrhagic fever with renal syndrome that occurs in Central and Northern Europe. Several studies have sought to identify risk factors for severe NE. However, elevated procalcitonin (PCT levels have not previously been investigated as a predictive marker for a severe course of NE. Methods: A cross-sectional prospective survey of 456 adults with serologically confirmed NE was performed. Results: PCT levels at the time of diagnosis were available for 43 out of 456 patients, and in 24 of these patients (56% PCT levels were elevated (“PCT positive”. C-reactive protein (CRP levels at admission to hospital and peak CRP levels during the acute course of the disease were higher in the PCT-positive compared with the PCT-negative group (pConclusions: Elevated PCT levels are common in patients with acute NE. There was no association between PCT levels and severity of disease, including AKI or thrombocytopenia. It is important to distinguish Puumala virus infection from other causes of AKI with thrombocytopenia. However, PCT might not be useful in differentiating hantavirus infection from bacterial infection.

    Full Text Available Sepsis is a critical condition often caused by bacterial infection and associated with death and mortality. The prognosis of this disease depends on early diagnosis and proper treatment. Definite diagnosis of sepsis is positive blood culture and this test needs a long time to perform, so other biochemical parameters such as procalcitonin serum level has been introduced. To determine sensitivity, specificity, positive and negative predictive value of procalcitonin serum level at first time and 72 h after admission and to compare it with blood culture test for diagnosis of sepsis. Blood sample for blood culture, prepheral blood smear at first time and procalcitonin serum level measuring by semi quantitative method at first and 72 h after admission were sampled. Nine patients had positive blood cultures. Peripheral blood smear was positive in 38 patients, (29 patients: gram stain positive, 6 patients: gram stain negative and 3 patients: both gram positive and gram negative. At first time 76.8% had positive procalcitonin (>0.5 ng mL-1 and after 72 h 65% of patients had positive procalcitonin. Sensitivity, specificity, positive and negative predictive value of procalcitonin at the first time were 100, 16,16 and 100% and for procalcitonin after 72 h respectively were 75, 35, 15 and 90%. This study showed that sensitivity of procalcitonin serum level can be used for diagnosis of sepsis. Procalcitonin increased as severity of sepsis and this study suggests high serum level of procalcitonin after 72 h might indicate poor outcome.

    Procalcitonin is the prohormone of calcitonin and present in minute quantities in health. However, during infection, its levels rise considerably and are correlated with the severity of the infection. Several assays have been developed for measurement of procalcitonin levels; in this article, we will briefly present the PCT-sensitive Kryptor(®) test (Brahms, Hennigsdorf, Germany), one of the most widely used assays for procalcitonin in recent studies. Many studies have demonstrated the value of procalcitonin levels for diagnosing sepsis and assessing disease severity. Procalcitonin levels have also been successfully used to guide antibiotic administration. However, procalcitonin is not specific for sepsis, and values need to be interpreted in the context of a full clinical examination and the presence of other signs and symptoms of sepsis.

    Background: Both procalcitonin (PCT) and plasma endotoxin levels cannot be solely used for a definite diagnosis of bacteremia or sepsis, and there has been few study comparing the values of the two biomarkers for the diagnosis of bacteremia. The aim of this study was to identify bacteria causing bacteremia and evaluate the role of the two biomarkers in the diagnosis of bacteremia in Intensive Care Unit (ICU). Methods: The medical records of 420 patients in ICU were retrospectively reviewed. Patients (n = 241) who met the inclusion criteria were subjected to blood culture (BC) for the analysis of the endotoxin or PCT levels. The exclusion criteria included the presence of infection with human immunodeficiency virus and/or AIDS, neutropenia without sepsis, pregnancy, treatment with immunosuppressive therapies, or blood diseases such as hematological tumors. Patients’ BC episodes were divided into BC negative, Gram-negative (GN) bacteria, Gram-positive bacteria, and fungi groups. The PCT and plasma endotoxin levels were compared in the different groups. Results: A total of 241 patients with 505 episodes of BC were analyzed. The GN bacteria group showed higher levels of PCT and endotoxin than the BC negative, Gram-positive bacteria, and fungi groups. GN bacteremia was more prevalent than Gram-positive bacteremia. The GN bacteremia caused by non-Enterobacteriaceae infection presented higher endotoxin level than that by Enterobacteriaceae, but no significant difference in PCT levels was observed between the two groups. The plasma endotoxin significantly differed among different groups and was bacterial species dependent. Conclusions: Plasma endotoxin was more related to GN than to Gram-positive bacteremia, and that endotoxin level was species dependent, but PCT level remained relatively more stable within the GN bacteria caused bacteremia. Both GN and positive bacteria caused bacteremia in the ICU patients in different regions of China. And PCT is a more valuable

    Unlike bacterial infections, the value of procalcitonin (PCT) in detecting fungal infections in leukaemia patients is not clear. To determine whether the monitoring of PCT coupled with C-reactive protein (CRP) and fibrinogen (Fib) could be helpful in the management of pulmonary aspergillosis (IPA) or mucormycosis (PM), we retrospectively analysed the evolution of PCT, CRP and Fib levels in 94 leukaemia patients with proven/probable IPA (n = 77) or PM (n = 17) from D-12 to D12 relative to IFI onset defined as D0. Overall, 2140 assays were performed. From D-12 to D0, 12%, 5% and 1.4% of patients had PCT >0.5, 1 and 1.5 μg l(-1) , respectively, while CRP was >50, 75 and 100 mg l(-1) in 84%, 70% and 57% and Fib was >4, 5 and 6 g l(-1) in 96%, 80% and 61% of cases respectively (P 1.5 μg l(-1) , while CRP >100 mg l(-1) and Fib >6 g l(-1) were observed in 80% and 75% of cases respectively (P < 10(-7) ). In leukaemia patients, IPA or PM was accompanied by a significant increase in CRP and Fib while PCT remained low. PMID:26931315

    Full Text Available P. falciparum malaria continues as the serial killer of over a million lives yearly, mainly for children in sub-Saharan Africa. For severe malaria, we are still on the quest for a prognostic marker of fatal outcome. We analysed the association between serum levels of Procalcitonin (PCT, a marker of septic inflammation, and clinical outcome in Senegalese patients admitted with confirmed cerebral malaria in the intensive care facility of Hopital Principal. A total of 98 patients living in the hypoendemic urban area of Dakar, Senegal, were enrolled during transmission seasons. Levels of PCT were compared between surviving vs the 26.5 % fatal cases in blood samples of the 3 days following hospitalisation. Mean PCT levels were elevated in patients with active infection, with a large range of values (0.1 to 280 nanog per mL, significantly higher on day 0 in fatal cases than in surviving (53.6 vs 27.3; P=0.01. No exact individual threshold level could indicate occurrence of fatality, however mortality could be most accurately predicted by PCT level above 69 nanog per ML and there was a very clear different profile of evolution of PCT levels on the 3 days of observation decreasing early from day 1 in surviving patients (P<10–3, contrary to fatal cases. These results indicate that PCT kinetic rather than intrinsic level could be of use to predict a reduced risk of fatality in patient with cerebral malaria and could serve as potential predicting marker for severe malaria.

    Objective To evaluate the efficacy of using procalcitonin (PCT) and interleukin-6 (IL-6) to differentiate sepsis from non-infectious systemic inflammatory response syndrome (SIRS). Methods We made a prospective study in a general intensive care unit at Peking Union Medical College Hospital. Twenty patients with sepsis and 31 patients with non-infectious SIRS were enrolled in this study. Serum concentrations of PCT, IL-6 and C-reactive protein (CRP) were determined within 24 h after clinical onset of sepsis or non-infectious SIRS. Leukocyte count, percentage of neutrophils, and absolute neutrophil count, as well as maximal body temperature were also recorded.Results Serum concentrations of PCT, IL-6, and CRP, as well as maximal body temperature, were significantly higher in septic patients [3.6 (1.8, 27.5) μg/L, 810±516 ng/L, 180±108 g/L, 38.6±1.2℃] than non-infectious SIRS patients [0.5 (0.2, 1.8) μg/L, 235±177 ng/L, 109±70 g/L, 37.9±0.9℃]. IL-6 and PCT exhibited the best discriminative power between sepsis and non-infectious SIRS, with sensitivity above 80% and specificity above 70%. A sepsis score with combination of IL-6 and PCT showed the best discriminative power with the area under the receiver operating characteristic curve of 0.923.Conclusions Assessing IL-6 and PCT levels are more reliable ways to differentiate sepsis from non-infectious SIRS, compared with conventional inflammatory parameters.

    In the last fifteen years, procalcitonin measurement has been evaluated as a rapid diagnostic aid for suspected infection. Procalcitonin is now widely used in any febrile patient despite the lack of evidence supporting that practice. Indeed, procalcitonine has proven effective in the intensive care setting, as a diagnostic aid for septic shock, as a prognostic instrument and to tailor the duration of antibiotic treatment. Studies in non intensive care settings are more recent and scarce. Procalcitonin has been assessed in the emergency department in patients with lower respiratory tract infections and in patients admitted for an acute febrile illness. Results are encouraging but preliminary, therefore procalcitonine measurement should be restricted to patients with criteria of severe infection for the time being. PMID:18018823

    Whether the levels of procalcitonin (PCT) in the serum and synovial fluid are effective indicators for distinguishing septic arthritis (SA) from non-infectious arthritis remains controversial. The present study aimed to evaluate whether PCT levels in fresh serum or fresh joint fluid may be used in the differential diagnosis of SA from rheumatoid arthritis (RA), osteoarthritis (OA) and gouty arthritis (GA). From January 2012 to June 2013, 23 patients with knee SA, 21 patients with RA, 40 patients with OA and 11 patients with GA were enrolled in the current study. The levels of PCT were measured within 24 h after specimen collection at room temperature. An enzyme-linked fluorescence assay (ELFA) was used to detect the levels of PCT in the serum and synovial fluid. The correlations between the levels of PCT in the serum and synovial fluid and the arthritic patient groups were determined by the Nemenyi test. Areas under the receiver operating characteristic (ROC) curve were calculated to evaluate the accuracy of the correlations. The levels of PCT in the serum and joint fluid of the patients in the SA group were higher compared with those of the other groups (Parthritis; however, the PCT levels in fresh synovial fluid are more sensitive and accurate indicators than PCT levels in fresh serum.

    Objective To discuss the clinical value of serum procalcitonin level in diagnosing biliary tract infection. Methods A total of 53 patients with obstructive jaundice were enrolled in this study. The serum procalcitonin level was determined in all patients by immunolofluoreseence sandwich method. Percutanous biliary drainage was performed in all patients. Based on the bile culture result and the clinical manifestations, the patients were divided into the bacterial infection group (n = 33) and the non-bacterial infection group (n = 20). The serum procalcitonin level, white blood cell (WBC) count and the percentage of neutrophilic granulocyte were determined, and the results were compared between the two groups. Results Taking 0.25 ng/ml as the positive threshold of serum procalcitonin level, the sensitivity and the specificity for the diagnosis of biliary tract bacterial infection were 91.9% and 87.5% respectively. When WBC of 8.89 × 109/L was taken as the positive threshold, the sensitivity and the specificity for the diagnosis of biliary tract bacterial infection were 54.8% and 83.3% respectively. If neutrophilic granulocyte of 74.25% was regarded as the positive threshold, the sensitivity and the specificity for the diagnosis of biliary tract bacterial infection were 66.1% and 70.8% respectively. The serum procalcitonin level in the bacterial infection group was significantly higher than that in the non-bacterial infection group (P < 0.05). Conclusion Determination of serum procalcitonin level is very helpful for the diagnosis of biliary tract bacterial infection with much higher sensitivity and specificity. Therefore, serum procalcitonin level can be used as an effective index for biliary tract bacterial infection.%目的 探讨血清降钙素原(PCT)浓度在胆道感染中的诊断价值.方法 采用荧光免疫夹心法检测53例梗阻性黄疸患者血清PCT浓度,所有患者均行经皮经肝穿刺胆管引流术,根据胆汁培养结果及临床症状

    Full Text Available INTRODUCTION: Ventilator-associated pneumonia (VAP is an important cause of mortality and morbidity in critically ill patients. We sought to determine the prognostic value of procalcitonin (PCT and C-reactive protein (CRP kinetics in critically ill patients who developed VAP. METHODS: Patients who were admitted to the intensive care unit (ICU and developed VAP were eligible. Patients were followed for 28 days after the pneumonia diagnosis and blood samples for PCT and CRP were collected on the day of the pneumonia diagnosis (D0, and days 3 (D3 and 7 (D7 after the diagnosis. Patients were grouped as survivors and non-survivors, and the mean PCT and CRP values and their kinetics were assessed. RESULTS: In total, 45 patients were enrolled. Of them, 22 (48.8% died before day 28 after the pneumonia diagnosis. There was no significant difference between the survivor and non-survivor groups in terms of PCT on the day of pneumonia diagnosis or CRP levels at any point. However, the PCT levels days 3 and 7 were significantly higher in the non-survivor group than the survivor group. Whereas PCT levels decreased significantly from D0 to D7 in the survivor group, CRP did not. A PCT level above 1 ng/mL on day 3 was the strongest predictor of mortality, with an odds ratio of 22.6. CONCLUSION: Serum PCT was found to be a superior prognostic marker compared to CRP in terms of predicting mortality in critically ill patients who developed VAP. The PCT level on D3 was the strongest predictor of mortality in VAP.

    Full Text Available Background Pneumonia is a major cause of morbidity and mortality in children under five years of age. Pneumonia can be of bacterial or viral origin. It is difficult to distinguish between these two agents based on clinical manifestations, as well as radiological and laboratory examinations. Furthermore, bacterial cultures take time to incubate and positive results may only be found in 10-30% of bacterial pneumonia cases. Procalcitonin has been used as a marker to distinguish etiologies, as bacterial infections tend to increase serum procalcitonin levels. Objective To determine the sensitivity, specificity, positive predictive value and negative predictive value of procalcitonin in community-acquired bacterial pneumonia. Method This cross-sectional study was conducted in the Pediatric Health Department of Dr. M. Djamil Hospital, Padang. Subjects were selected by consecutive sampling. Procalcitonin measurements and PCR screening were performed on blood specimens from 32 pneumonia patients and compared. Results Of the 32 subjects, most were boys (56.25%, under 5 years of age (99%, and had poor nutritional status (68.75%. Using a cut-off point of 0.25 ng/mL, procalcitonin level had a sensitivity of 92%, specificity 50%, positive predictive value 88%, and negative predictive value 60% for diagnosing bacterial pneumonia. Using a cut-off point of 0.5 ng/mL, procalcitonin level had a specificity of 46%, specificity 83%, positive predictive value 91%, and negative predictive value 25%. Conclusion A cut-off point of 0.25 ng/mL of procalcitonin level may be more useful to screen for bacterial pneumonia than a cut-off point of 0.5 ng / mL. However, if the 0.25 ng/mL cut-off point is used, careful monitoring will be required for negative results, as up to 40% may actually have bacterial pneumonia. [Paediatr Indones. 2015;55:65-9.].

    2016-06-01

    Procalcitonin is a sensitive and specific marker of bacterial infection; low results allow clinicians to safely de-escalate antibiotics. This retrospective cohort study aimed to determine the effect of low procalcitonin results on withholding, discontinuing, or de-escalating antibiotics in hospitalized patients at a tertiary care center. Antibiotics were initiated or continued without de-escalation in 55% of patients with low procalcitonin results. Among patients with low procalcitonin results, the primary service, but not measures of patient complexity, disease severity, or underlying disease process (lower respiratory tract infection evaluation versus systemic inflammatory response syndrome/possible sepsis) was associated with initiation or continued broad-spectrum antibiotic use. Provider-level factors may be an important variable in the initiation or continued use of broad-spectrum antibiotics for patients with low procalcitonin levels. PMID:27251126

    1989-05-01

    The concentration of abnormal prothrombin, or the protein induced by vitamin K absence or antagonist II (PIVKA-II) in 102 patients with hepatic disorders was measured by an enzyme immunoassay method. The concentration of PIVKA-II in the plasma was elevated in 11 out of 18 patients with hepatocellular carcinoma and also in a patient with hepatoblastoma. There was no correlation between serum alpha-fetoprotein and plasma PIVKA-II levels. The PIVKA-II level was normal in 11 patients who had metastatic carcinoma or cholangiocellular carcinoma. Moreover, benign diseases of the liver did not cause an elevation in PIVKA-II. PIVKA-II might be an useful marker of hepatocellular carcinoma because, like alpha-fetoprotein, its level changes in close relation to the effects of treatment.

    Full Text Available PURPOSE: The final decision for discharge from the intensive care unit (ICU is uncertain because it is made according to various patient parameters; however, it should be made on an objective evaluation. Previous reports have been inconsistent and unreliable in predicting post-ICU mortality. To identify predictive factors associated with post-ICU mortality, we analyzed physiological and laboratory data at ICU discharge. METHODS: Patients admitted to our ICU between September 2012 and August 2013 and staying for critical care>2 days were included. Sequential Organ Failure Assessment (SOFA score; systemic inflammatory response syndrome score; white blood cell count; and serum C reactive protein, procalcitonin (PCT, interleukin-6 (IL-6, lactate, albumin, and hemoglobin levels were recorded. The primary end point was 90-day mortality after ICU discharge. Two hundred eighteen patients were enrolled (195 survivors, 23 non-survivors. RESULTS: Non-survivors presented a higher SOFA score and serum PCT, and IL-6 levels, as well as lower serum albumin and hemoglobin levels. Serum PCT, albumin, and SOFA score were associated with 90-day mortality in multiple logistic regression analysis. Hosmer-Lemeshow test showed chi-square value of 6.96, and P value of 0.54. The area under the curve (95% confidence interval was 0.830 (0.771-0.890 for PCT, 0.688 (0.566-0.810 for albumin, 0.861 (0.796-0.927 for SOFA score, and increased to 0.913 (0.858-0.969 when these were combined. Serum PCT level at 0.57 ng/mL, serum albumin at 2.5 g/dL and SOFA score at 5.5 predict 90-day mortality, and high PCT, low albumin and high SOFA groups had significantly higher mortality. Serum PCT and SOFA score were significantly associated with survival days after ICU discharge in Cox regression analysis. CONCLUSIONS: Serum PCT level and SOFA score at ICU discharge predict post-ICU mortality and survival days after ICU discharge. The combination of these two and albumin level might enable

    Full Text Available Context: Procalcitonin is a biomarker of bacterial sepsis. It is unclear if scrub typhus, a rickettsial illness, is associated with elevated procalcitonin levels. Aim: To assess if scrub typhus infection is associated with high procalcitonin levels and whether high levels portend a poorer prognosis. Setting and Design: Retrospective study of patients with severe scrub typhus infection, admitted to the medical intensive care unit of a tertiary care university affiliated teaching hospital. Materials and Methods: Eighty-four patients with severe scrub typhus infection that also had procalcitonin levels were assessed. Statistical Analysis: Relationship between procalcitonin and mortality explored using univariate and multivariate analyses. Results: The mean (±standard deviation age was 40.0 ± 15.5 years. Patients were symptomatic for 8.3 ± 4.3 days prior to presentation. The median admission procalcitonin level was 4.0 (interquartile range 1.8 to 8.5 ng/ml; 59 (70.2% patients had levels >2 ng/ml. Invasive mechanical ventilation was required in 65 patients; 20 patients died. On univariate analysis, admission procalcitonin was associated with increased odds of death [odds ratio (OR 1.09, 95% confidence interval (CI 1.03 to 1.18]. On multivariate logistic regression analysis including procalcitonin and APACHE-II score, the APACHE-II score was significantly associated with mortality (OR 1.16, 95% CI 1.06 to 1.30, P = 0.004 while a trend was observed with procalcitonin (OR 1.05, 95%CI 1.01 to 1.13, P = 0.09. The area under the receiver operating characteristic (ROC curve, AUC, for mortality was 0.77 for procalcitonin and 0.78 for APACHE-II. Conclusions: Procalcitonin is elevated in severe scrub typhus infection and may be associated with higher mortality.

    Conclusions: Plasma endotoxin was more related to GN than to Gram-positive bacteremia, and that endotoxin level was species dependent, but PCT level remained relatively more stable within the GN bacteria caused bacteremia. Both GN and positive bacteria caused bacteremia in the ICU patients in different regions of China. And PCT is a more valuable biomarker than endotoxin in the diagnosis of bacteremia.

  9. Presepsin (soluble CD14 subtype) and procalcitonin levels for mortality prediction in sepsis: data from the Albumin Italian Outcome Sepsis trial

    Science.gov (United States)

    2014-01-01

    Introduction Sepsis, a leading cause of death in critically ill patients, is the result of complex interactions between the infecting microorganisms and the host responses that influence clinical outcomes. We evaluated the prognostic value of presepsin (sCD14-ST), a novel biomarker of bacterial infection, and compared it with procalcitonin (PCT). Methods This is a retrospective, case–control study of a multicenter, randomized clinical trial enrolling patients with severe sepsis or septic shock in ICUs in Italy. We selected 50 survivors and 50 non-survivors at ICU discharge, matched for age, sex and time from sepsis diagnosis to enrollment. Plasma samples were collected 1, 2 and 7 days after enrollment to assay presepsin and PCT. Outcome was assessed 28 and 90 days after enrollment. Results Early presepsin (day 1) was higher in decedents (2,269 pg/ml, median (Q1 to Q3), 1,171 to 4,300 pg/ml) than in survivors (1,184 pg/ml (median, 875 to 2,113); P = 0.002), whereas PCT was not different (18.5 μg/L (median 3.4 to 45.2) and 10.8 μg/L (2.7 to 41.9); P = 0.31). The evolution of presepsin levels over time was significantly different in survivors compared to decedents (P for time-survival interaction = 0.03), whereas PCT decreased similarly in the two groups (P = 0.13). Presepsin was the only variable independently associated with ICU and 28-day mortality in Cox models adjusted for clinical characteristics. It showed better prognostic accuracy than PCT in the range of Sequential Organ Failure Assessment score (area under the curve (AUC) from 0.64 to 0.75 vs. AUC 0.53 to 0.65). Conclusions In this multicenter clinical trial, we provide the first evidence that presepsin measurements may have useful prognostic information for patients with severe sepsis or septic shock. These preliminary findings suggest that presepsin may be of clinical importance for early risk stratification. PMID:24393424

    Full Text Available Objective:Early diagnosis of neonatal sepsis and appropriate treatment decreases the mortality and morbidity of these infants. The aim of this study was to assess the role of procalcitonin (PCT as a marker in the early diagnosis, treatment and follow-up of neonatal sepsis. Methods:Thirty-eight neonates with clinical (n=8, suspected (n=19 and proven sepsis (n=11 were evaluated. The PCT levels were measured by immunoluminoassay before and on day 5 of treatment. PTC levels of 0.5-2 ng/ml, 2.1-10 ng/ml and >10 ng/ml were considered as weakly positive, positive, and strongly positive, respectively. The sepsis screen tests and cultures of blood or other sterile body fluids in these three groups of infants were recorded. Findings:The levels of PCT in proven sepsis group were higher than that in other groups. Strongly positive PTC level was seen in none of 8 cases of clinical sepsis, 4 of 19 suspected and in 10 of 11 cases with proven sepsis. PCT levels were dramatically decreased in three groups on day 5 of treatment. Conclusion:The results show that the serum procalcitonin levels seem to be significantly increased in proven sepsis and decrease dramatically in all types of sepsis after appropriate treatment.

    Full Text Available Objectives. Our objective is to compare maternal plasma procalcitonin concentrations in preterm premature rupture of membranes (pPROM and premature rupture of membranes (PROM at term with their levels in uncomplicated pregnancy, and to determine whether these concentrations are useful in the diagnosis of pPROM cases suspected of infection and in the prediction of pPROM-to-delivery interval. Study design. Forty eight patients with pPROM, 30 with PROM at term, 31 healthy women at preterm gestation, and 33 healthy women at term were included. In pPROM group, analysis of procalcitonin concentrations with reference to leucocytosis, serum C-reactive protein, vaginal fluid culture, neonatal infection, histological chorioamnionitis and pPROM-to-delivery interval was carried out. Results. Procalcitonin concentrations in pPROM and PROM at term cases were comparable. However, in both groups procalcitonin values were significantly higher than in healthy controls in approximate gestational age. In pPROM group, procalcitonin concentrations between the patients with and without laboratory indices of infection were comparable, as well as between patients who gave birth to newborns with and without congenital infection, and between patients with and without histological chorioamnionitis. The predictive values of procalcitonin determinations were poor. Conclusion. The value of maternal plasma procalcitonin determinations in the diagnostics of pPROM cases suspected of intraamniotic infection, as well as for the prediction of pPROM-to-delivery interval, newborn's infection or histological chorioamnionitis is unsatisfactory. However, procalcitonin concentrations are elevated, both in patients with preterm and term PROMs in comparison to healthy pregnants, and therefore further evaluations are necessary to establish the role of procalcitonin in the pathophysiology of pregnancy.

    Full Text Available Background Pneumonia is a major cause of morbidity andmortality in children under five years of age. Pneumonia can be ofbacterial or viral origin. It is difficult to distinguish between thesetwo agents based on clinical manifestations, as well as radiologicaland laboratory examinations. Furthermore, bacterial cultures taketime to incubate and positive results may only be found in 10-30%of bacterial pneumonia cases. Procalcitonin has been used as amarker to distinguish etiologies, as bacterial infections tend toincrease serum procalcitonin levels.Objective To determine the sensitivity, specificity, positivepredictive value and negative predictive value of procalcitoninin community-acquired bacterial pneumonia.Method This cross-sectional study was conducted in thePediatric Health Department of Dr. M. Djamil Hospital, Padang.Subjects were selected by consecutive sampling. Procalcitoninmeasurements and PCR screening were performed on bloodspecimens from 32 pneumonia patients and compared.Results Of the 32 subjects, most were boys (56.25%, under 5years of age (99%, and had poor nutritional status (68.75%.Using a cut-off point of 0.25 ng/mL, procalcitonin level hada sensitivity of 92%, specificity 50%, positive predictive value 88%, and negative predictive value 60% for diagnosing bacterial pneumonia. Using a cut-off point of 0.5 ng/mL, procalcitonin level had a specificity of 46%, specificity 83%, positive predictive value 91%, and negative predictive value 25%.Conclusion A cut-off point of 0.25 ng/mL of procalcitonin level may be more useful to screen for bacterial pneumonia than a cutoff point of 0.5 ng / mL. However, if the 0.25 ng/mL cut-off point is used, careful monitoring will be required for negative results, as up to 40% may actually have bacterial pneumonia. [PaediatrIndones. 2015;55:65-9.].

    Fiona J McCann

    Full Text Available Procalcitonin has been shown to be useful in separating infection from non-infective disorders. However, infection is often paralleled by tissue inflammation. Most studies supporting the use of procalcitonin were confounded by more significant inflammation in the infection group. Few studies have examined the usefulness of procalcitonin when adjusted for inflammation.Pleural inflammation underlies the development of most exudative effusions including pleural infection and malignancy. Pleurodesis, often used to treat effusions, involves provocation of intense aseptic pleural inflammation. We conducted a two-part proof-of-concept study to test the specificity of procalcitonin in differentiating infection using cohorts of patients with pleural effusions of infective and non-infective etiologies, as well as subjects undergoing pleurodesis.We measured the blood procalcitonin level (i in 248 patients with pleural infection or with non-infective pleural inflammation, matched for severity of systemic inflammation by C-reactive protein (CRP, age and gender; and (ii in patients before and 24-48 hours after induction of non-infective pleural inflammation (from talc pleurodesis.1 Procalcitonin was significantly higher in patients with pleural infection compared with controls with non-infective effusions (n = 32 each group that were case-matched for systemic inflammation as measured by CRP [median (25-75%IQR: 0.58 (0.35-1.50 vs 0.34 (0.31-0.42 µg/L respectively, p = 0.003]. 2 Talc pleurodesis provoked intense systemic inflammation, and raised serum CRP by 360% over baseline. However procalcitonin remained relatively unaffected (21% rise. 3 Procalcitonin and CRP levels did not correlate. In 214 patients with pleural infection, procalcitonin levels did not predict the survival or need for surgical intervention.Using a pleural model, this proof-of-principle study confirmed that procalcitonin is a biomarker specific for infection and is not affected by non

    Plasma procalcitonin (PCT) is a highly specific marker for the diagnosis of bacterial infection and sepsis. Studies have demonstrated its role in the setting of sepsis and acute pancreatitis. This study aims to analyze and compare the prognostic efficacy of plasma procalcitonin strip test in acute pancreatitis. A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma procalcitonin was estimated by the semiquantitative strip test. The study included a total of 50 patients diagnosed to have acute pancreatitis. Data was collected and statistically analyzed using SPSS version 17. Thirty-nine out of the 50 patients (78 %) were males with a mean age of 46.8 years (range, 25-78 years) and 25 patients (50 %) had ethanol-induced pancreatitis, while 13 patients (26 %) had gall stone pancreatitis. Plasma PCT values were found to correlate better than CRP levels and total leukocyte count with the total duration of hospitalization, ITU, and ICU stay, as well as with the progression to severe acute pancreatitis. A cut off for plasma PCT of >2 ng/mL was found to be 100 % sensitive and 100 % specific and a cut off for CRP of >19 mg/dL was 70 % sensitive and 65 % specific for predicting the progression to severe acute pancreatitis. Plasma PCT also correlated well with antibiotic requirement. A cut off value of >0.5 ng/mL for plasma PCT was 100 % sensitive and 80 % specific and a cut off value of >18 mg/dL for CRP was 86 % sensitive and 63 % specific for predicting antibiotic requirement. Plasma procalcitonin is an early and reliable prognostic indicator in acute pancreatitis. The procalcitonin strip test is a rapid test which is useful in analyzing prognosis in patients with acute pancreatitis. PMID:27011501

    Full Text Available Aim: Febrile neutropenia is the major cause of mortality and morbidity in cancer patients. For this reason, early diagnosis of severe infections and appropriate antimicrobial therapy are very important. The aim of this study was to investigate the difference between C-reactive protein (CRP and procalcitonin in determining the sepsis and its severity. Materials and Method: A total of 30 children (35 episodes with febrile neutropenia who were hospitalized in the Uludag University, Pediatric Hematology and Oncology Unit were included in this prospective study. The blood samples for CRP and procalcitonin were collected daily between 0 to 5th days. Serum CRP and procalcitonin levels were compared with culture positivity, prolonged fever, mucositis and absolute granulosit count (AGC. Results: A total of 16 patients (56% diagnosed with acute leukemia and, 14 patients (46% having solid tumours were evaluated. In sequential analysis of febrile episodes, both the median of procalcitonin and the CRP concentrations showed the same tendency and there was no significant correlation between them (r=0.2, p>0.05. There was no significant association between CRP and procalcitonin among those having positive culture and mucositis. However, CRP values at the 3rd, 4th and 5th days were significantly higher in the patients with AGC100/mm3. Similarly, CRP values were significantly higher at the 1st, 2nd, 3rd and 4th days among the patients having prolonged fever. Conclusion: Our study suggests that there is no difference between CRP and procalcitonin in determining sepsis and its severity. Although procalcitonin is a valuable acute phase reactant in non-neutropenic patients, larger prospective investigations are needed to show the prognostic value of procalcitonin in neutropenic patients.

    Full Text Available Estimation of serum procalcitonin (PCT levels is of great interest in rheumatology in both the diagnosis of coinfectionsand the differential diagnosis between rheumatic disease activity and the current infectious process.Objective: to estimate the value of PCT as a specific marker for generalized and local infection in rheumatic patients.Subjects and methods. A retrospective study investigated the case histories of 100 inpatients examined and treated at the V.A. Nasonova Research Institute of Rheumatology. Serum PCT concentrations were determined by a quantitative electrochemiluminescence assay using a Cobas E 411 analyzer (Roche, Switzerland.Results. Infectious diseases were diagnosed in 41 of the 100 patients. The infectious process was generalized and local in 11 and 30 cases, respectively. In the patients with generalized infection, the level of PCT was more than 2.0 ng/ml in 81.8% of the cases. In the local infection and non-infection groups, it was below 0.5 mg/ml in 70 and 84.7% ofcases, respectively. In the generalized infection group, the content of PCT was significantly higher (3.6 [2.3; 10.5] than in the local infection (0.24 [0.15; 0.7]; р = 0.004 and non-infection (0.15 [0.09; 0.26]; р = 0.0001 groups. It did not depend on rheumatic disease activity. C-reactive protein (CRP levels and erythrocyte sedimentation rate (ESRcorrelated with PCT concentrations in different patient groups. ROC analysis showed the optimal sensitivity (82% and specificity (98% of PCT as a marker of systemic infection only in the rheumatic patients with its concentration of ≥2.3 ng/ml.Conclusion. The determination of PCT is certain to contribute to the diagnosis of generalized infections and the differential diagnosis of systemic rheumatic diseases and infectious ones.

    Full Text Available Background and Aims: To evaluate the prognostic value of change (fall in serum procalcitonin level (PCT in critically ill adults with severe sepsis/septic shock. Methods: This was a prospective observational study in a general purpose Intensive Care Unit of a teaching Institute. PCT was measured at admission (D0 and after 72-96 h (D4 by electrochemi-luminescence immunoassay (BRAHMS PCT kit in adults (>18 years admitted with severe sepsis or septic shock. Change in procalcitonin values from D0 to D4 was correlated with the primary outcome, that is, 28 days mortality. All results are reported as median (interquartile range. Results: A total of 171 (100 males of 181 patients were included. The median age was 46 years (range 19-79. 137 patients were in septic shock and 34 in severe sepsis. The sequential organ failure assessment (SOFA score in all patients was 11 (9-14.91 (53.2% patients survived at 28 days (survivors. The baseline procalcitonin was similar in two groups (3.48 [1.04-15.85] vs. 5.27 [1.81-23.57] ng/ml in survivors and nonsurvivors [NS] respectively. The procalcitonin change was 1.58 (0.20-8.52 in survivors and 0.28 (-1.38-6.17 in NS (P = 0.01. The C-statistic of percentage change in procalcitonin from D0 to D4 to predict survival was 0.73 (95% confidence interval [CI]: 0.65-0.82 when compared to 0.78 (95% CI: 0.71-0.86 for change of SOFA score. For an absolute fall in procalcitonin of >1 ng/ml, a 70% fall predicted survival with 75% sensitivity and 64% specificity. Conclusions: In critically ill-patients with severe sepsis/septic shock, change (fall in procalcitonin is associated with good outcome.

    Full Text Available Abstract Background The purpose of this study was to explore the diagnostic value of soluble triggering receptor expressed on myeloid cells 1 (sTREM-1, procalcitonin (PCT, and C-reactive protein (CRP serum levels for differentiating sepsis from SIRS, identifying new fever caused by bacteremia, and assessing prognosis when new fever occurred. Methods We enrolled 144 intensive care unit (ICU patients: 60 with systemic inflammatory response syndrome (SIRS and 84 with sepsis complicated by new fever at more than 48 h after ICU admission. Serum sTREM-1, PCT, and CRP levels were measured on the day of admission and at the occurrence of new fever (>38.3°C during hospitalization. Based on the blood culture results, the patients were divided into a blood culture-positive bacteremia group (33 patients and blood culture-negative group (51 patients. Based on 28-day survival, all patients, both blood culture-positive and -negative, were further divided into survivor and nonsurvivor groups. Results On ICU day 1, the sepsis group had higher serum sTREM-1, PCT, and CRP levels compared with the SIRS group (P P Conclusions Serum sTREM-1, PCT, and CRP levels each have a role in the early diagnosis of sepsis. Serum sTREM-1, with the highest sensitivity and specificity of all indicators studied, is especially notable. sTREM-1, PCT, and CRP levels are of no use in determining new fever caused by bacteremia in ICU patients, but sTREM-1 levels reflect the prognosis of bacteremia.

    Background Serum procalcitonin levels have been used as a biomarker of invasive bacterial infection and recently have been advocated to guide antibiotic therapy in patients with chronic obstructive pulmonary disease (COPD). However, rigorous studies correlating procalcitonin levels with microbiologic data are lacking. Acute exacerbations of COPD (AECOPD) have been linked to viral and bacterial infection as well as noninfectious causes. Therefore, we evaluated procalcitonin as a predictor of viral versus bacterial infection in patients hospitalized with AECOPD with and without evidence of pneumonia. Methods Adults hospitalized during the winter with symptoms consistent with AECOPD underwent extensive testing for viral, bacterial, and atypical pathogens. Serum procalcitonin levels were measured on day 1 (admission), day 2, and at one month. Clinical and laboratory features of subjects with viral and bacterial diagnoses were compared. Results In total, 224 subjects with COPD were admitted for 240 respiratory illnesses. Of these, 56 had pneumonia and 184 had AECOPD alone. A microbiologic diagnosis was made in 76 (56%) of 134 illnesses with reliable bacteriology (26 viral infection, 29 bacterial infection, and 21 mixed viral bacterial infection). Mean procalcitonin levels were significantly higher in patients with pneumonia compared with AECOPD. However, discrimination between viral and bacterial infection using a 0.25 ng/mL threshold for bacterial infection in patients with AECOPD was poor. Conclusion Procalcitonin is useful in COPD patients for alerting clinicians to invasive bacterial infections such as pneumonia but it does not distinguish bacterial from viral and noninfectious causes of AECOPD.

    Full Text Available Evapotranspiration (ET is an important component of the wetland water budget. Water level declines in Poyang Lake, the largest freshwater lake in China, have caused concerns, especially during low water levels. However, how wetland ET and its partitioning respond to abnormally low water levels is unclear. In this study, wetland ET was estimated with MODIS data and meteorological data. The wetland ET partitioning and its relationship with abnormally low water levels were analyzed for 2000–2013. The results showed that the water evaporation rate (Ewater was larger than the land ET rate (ETland; the ETland/Ewater ranged from 0.77 to 0.99. When the water level was below 12.8 m, the ET partition ratio was larger than 1, which indicates that wetland ET comes from land surface ET more than water evaporation. The negative standardized water level index (SWI was used to represent an abnormally low water level in the wetland. Although the monthly wetland ET decreased as the negative SWI decreased, ETland was higher than the average under negative SWI conditions from September to December, when the water level decreased. The abnormally low water level induced more water loss from the land surface, especially when the water level decreased, which reduced the available water resources along the wetland shore.

Blood culture and PCT were evaluated at onset of signs of infection. PCT levels in serum were investigated by semi-quantitative solid-phase immune chromatography. The antibacterial agents were used according to the results of PCT. The curative effects were evaluated until one week. The results showed that there were statistically different (P <0.01) between infection group and no infection group in PCT levels. The PCT serum level greater than 0.5ng/mL predicted an infection and with a sensitivity of 90.9% and specificity of 96.7%. The method of PCT-Q was more sensitive than the blood cul ture(P <0.01). PCT values returned to normal(<0.5ng/mL)by 3 to 7 days of appropriate antibiotic therapy. The method of PCT-Q is more sensitive for early diagnosis of pathogens

    The purpose of this systematic review was to assess the evidence for use of routine procalcitonin testing to diagnose the presence of sepsis in the burn patient. The electronic databases MEDLINE, Cochrane, CINAHL, ProQuest, and SCOPUS were searched for relevant studies using the MeSH terms burn, infection, procalcitonin, and meta-analysis. The focus of the review was the adult burn population, but other relevant studies of critically ill patients were included as data specific to the patient with burns are limited. Studies were compiled in tabular form and critically appraised for quality and level of evidence. Four meta-analyses, one review of the literature, one randomized controlled trial, nine prospective observational, and three retrospective studies were retrieved. Six of these studies were specific to the burn population, with one specific to burned children. Only one meta-analysis, one adult burn and one pediatric burn study reported no benefit of procalcitonin testing to improve diagnosis of sepsis or differentiate sepsis from non-infectious systemic inflammatory response. The collective findings of the included studies demonstrated benefit of incorporating procalcitonin assay into clinical sepsis determination. Evaluation of the burn specific studies is limited by the use of guidelines to define sepsis and inconsistent results from the burn studies. Utility of the procalcitonin assay is limited due to the lack of availability of rapid, inexpensive tests. However, it appears procalcitonin assay is a safe and beneficial addition to the clinical diagnosis of sepsis in the burn intensive care unit.

    Cryptococcal meningitis is considered rare in immunocompetent patients and is mainly a disease of immunocompromised patients. We report a case of cryptococcal meningitis, due to Cryptococcus neoformans, in an apparently healthy individual with abnormal levels of isolated immunological markers. Regardless of the patient's immune status, the result of the disease can be serious unless the disease is diagnosed early. PMID:27402508

    Hyperhomocysteinemia and abnormal blood lipids are independent risk factors for stroke. However, whether both factors exert a synergistic effect in the onset of stroke remains unclear. The present study is a retrospective analysis of 2 089 cases of stroke and 2 089 control cases of simple inter-vertebral disk protrusion using a paired multivariate logistic regression method. Adjusting for known confounding variables including the patients’ age, gender, smoking status, alcohol consumption status, patient and family medical history, and clinical biochemical indices, elevated homocysteine level was related to the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids showed a 40.9%increase in the risk for stroke compared to patients with normal ho-mocysteine levels and blood lipids (odds ratio 1.409;95%confidence interval 1.127-1.761). These results indicate that elevated homocysteine and abnormal blood lipids exert synergistic effects in the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids are predis-posed to stroke.

    ABSTRACT A rapid and reliable test for detection of complicated appendicitis would be useful when deciding whether emergency surgery is required. We investigated the clinical usefulness of procalcitonin for identifying acute complicated appendicitis. We retrospectively analyzed 63 patients aged ≥15 years who underwent appendectomy without receiving antibiotics before admission and had preoperative data on the plasma procalcitonin level (PCT), body temperature (BT), white blood cell count (WBC), neutrophil / lymphocyte ratio (N/L ratio), and C-reactive protein level (CRP). Patients were classified into 3 groups: group A (inflammatory cell infiltration of the appendix with intact mural architecture), group B (inflammatory cell infiltration with destruction of mural architecture, but without abscess or perforation), and group C (macroscopic abscess and/or perforation). For identifying destruction of mural architecture, the diagnostic accuracy of PCT was similar to that of BT or CRP. However, the diagnostic accuracy of PCT was highest among the five inflammatory indices for identifying abscess and/or perforation, with the positive predictive value of PCT for abscess and/or perforation being higher than that of CRP (73% vs. 48%). Univariate analysis of the predictors of abscess and/or perforation revealed that a plasma PCT level ≥0.46 ng/mL had the highest odds ratio (30.3 [95% confidence interval: 6.5–140.5] versus PCT <0.46 ng/mL). These findings indicate that procalcitonin is a useful marker of acute appendicitis with abscess and/or perforation. PMID:27019529

    The aim of our study was to evaluate the prognostic value of serum procalcitonine (PCT) assay in adult respiratory infections. Forty-nine patients admitted with pleurisy, community-acquired pneumonia, tuberculosis, infection were included in this prospective study. PCT was assayed on admission and discharge. Biological and clinical parameters of gravity were also evaluated. Twenty patients had elevated PCT of more than 0.50 ng/ml. In 29 patients, PCT was undetectable. The serum PCT level was normal in the patients with tuberculosis, infection, pneumocytosis. PCT did not correlate with the biological and clinical markers of the disease severity but the evolution of PCT correlated with the evolution of C-reactive-protein (r = 0.58, p < 0.05). PCT seems to be an early marker of the evolution of respiratory infections, but it does not help to establish prognosis. Further studies are necessary to assess the potential value of PCT in more severe respiratory infections requiring assisted ventilation. PMID:10685471

    This study evaluated the application of positive reinforcement training (PRT) as an intervention for abnormal behaviors in singly housed laboratory rhesus macaques at 2 large primate facilities. Training involved basic control behaviors and body-part presentation. The study compared baseline behavioral data on 30 adult males and 33 adult females compared with 3 treatment phases presented in counterbalanced order: 6 min per week of PRT, 20 or 40 min per week of PRT, and 6 min per week of unstructured human interaction (HI). Within-subject parametric tests detected no main or interaction effects involving experimental phase. However, among a subset of subjects with levels of abnormal in the top quartile of the range (n = 15), abnormal behavior was reduced from 35% to 25% of samples with PRT but not with HI. These results suggest that short durations of PRT applied as enrichment for this species and in this context may not in itself be sufficient intervention for abnormal behavior because levels remained high. However, it may be appropriate as an adjunct to other interventions and may be best targeted to the most severely affected individuals.

    The aim of this biomedical trial was to clarify the physiological role of procalcitonin (PCT) in renal parenchyma apoptosis and fibrosis caused by acute childhood pyelonephritis. This prospective study enrolled 183 children. All children were treated with bi-therapy according to the French consensus on acute pyelonephritis treatment dated November 16, 1990: intra-vascular administration of ceftriaxone 50 mg/kg/day and netromicine 7 mg/kg/day during the first 48 hours, followed by specific antibiotherapy suited to antibiogram. On admission, PCT, C-reactive protein, and phospholipase A2 were quantified in serum. Scintigraphy monitoring with 99mTc-DMSA was performed on day 4 and 9 months later, in the presence of persistent abnormalities. On day 4, 78% presented renal parenchyma alterations and 30% renal fibrosis 9 months after admission. Paradoxically, PCT level was significantly lower in the presence of renal fibrosis due to cell apoptosis (4.19 vs 7.59 μgL−1). A significant increase in PCT indicated favorable progress (recovery 7.55 vs aggravation 3.34) and no difference between recovery and improvement. This result suggests the protective effect of PCT against apoptosis by nitric oxide down-regulation. PMID:21694876

    Oxidative stress can cause methionine oxidation that has been implicated in various proteins malfunctions, if not adequately reduced by the methionine sulfoxide reductase system. Recent evidence has found oxidized methionine residues in neurodegenerative conditions. Previously, we have described elevated levels of brain pathologies and an abnormal walking pattern in the methionine sulfoxide reductase A knockout (MsrA(-/-)) mouse. Here we show that MsrA(-/-) mice have compromised complex task learning capabilities relative to wild-type mice. Likewise, MsrA(-/-) mice exhibit lower locomotor activity and altered gait that exacerbated with age. Furthermore, MsrA(-/-) mice were less responsive to amphetamine treatment. Consequently, brain dopamine levels were determined. Surprisingly, relative to wild-type mice, MsrA(-/-) brains contained significantly higher levels of dopamine up to 12 months of age, while lower levels of dopamine were observed at 16 months of age. Moreover, striatal regions of MsrA(-/-) mice showed an increase of dopamine release parallel to observed dopamine levels. Similarly, the expression pattern of tyrosine hydroxylase activating protein correlated with the age-dependent dopamine levels. Thus, it is suggested that dopamine regulation and signaling pathways are impaired in MsrA(-/-) mice, which may contribute to their abnormal behavior. These observations may be relevant to age-related neurological diseases associated with oxidative stress.

    Oxidative stress can cause methionine oxidation that has been implicated in various proteins malfunctions, if not adequately reduced by the methionine sulfoxide reductase system. Recent evidence has found oxidized methionine residues in neurodegenerative conditions. Previously, we have described elevated levels of brain pathologies and an abnormal walking pattern in the methionine sulfoxide reductase A knockout (MsrA−/−) mouse. Here we show that MsrA−/− mice have compromised complex task learning capabilities relative to wild-type mice. Likewise, MsrA−/− mice exhibit lower locomotor activity and altered gait that exacerbated with age. Furthermore, MsrA−/− mice were less responsive to amphetamine treatment. Consequently, brain dopamine levels were determined.

    Full Text Available Febrile neutropenia is defined as a fever >101°F for 1 hour, with an absolute neutrophil count of ≤500 cells/microliter, or an ANC of ≤1000 cells/microliter with a projected nadir of ≤500 cells/microliter. In haematological malignancies it is the common complication and requires broad-spectrum antibacterial therapy. Clinical examination and cultures fail to detect a pathogen or an infectious focus in 25–50%, which are classified as pyrexia of unknown origin (PUO. Patient with pyrexia of unknown origin may receive long duration of antibiotic treatment as the cause is unclear of being infective or not. Febrile neutropenia is a common complication of many chemotherapeutic regimens for all types of cancers. Mortality and Morbidity is high particularly in elderly, immuno-compromised. Approximately 20- 40 % of patients with severe sepsis and 45-60% patients with septic shock die within 15-20 days. This study was done to know the sources of infection and to assess the diagnostic value of serum Procalcitonin and its relation with mortality in various stages of sepsis. Sepsis incidence was more in patient age more than 55yrs. the most common source of sepsis was respiratory tract infection. Serum PCT proved to be an indicator of sepsis in ill patients, with sensitivity of 91%. Presence of both persistent and profound neutropenia was associated with a much higher mortality. The occurrence of infection is directly proportional to the degree of neutropenia, at the onset of fever the PCT levels will not be helpful for the decision to start or stop the antibacterial therapy, and a PCT value higher than 0.5ng/ml in pyrexia of unknown origin might suggest a possibility of occult infection, i.e. with lacking microbiological and clinical documentation. A delayed PCT peak higher than0.5ng/ml contributes to the early diagnosis of fungal disease.

    2016-01-01

    Full Text Available Background: Timely decision making in Intensive Care Unit (ICU is very essential to improve the outcome of critically sick patients. Conventional scores like Acute Physiology and Chronic Health Evaluation (APACHE IV are quite cumbersome with calculations and take minimum 24 hours. Procalcitonin has shown to have prognostic value in ICU/Emergency department (ED in disease states like pneumonia, sepsis etc. NTproBNP has demonstrated excellent diagnostic and prognostic importance in cardiac diseases. It has also been found elevated in non-cardiac diseases. We chose to study the prognostic utility of these markers on ICU admission. Settings and Design: Retrospective observational study. Materials and Methods: A Retrospective analysis of 100 eligible patients was done who had undergone PCT and NTproBNP measurements on ICU admission. Their correlations with all cause mortality, length of hospital stay, need for ventilator support, need for vasopressors were performed. Results: Among 100 randomly selected ICU patients, 28 were non-survivors. NTproBNP values on admission significantly correlated with all cause mortality (P = 0.036, AUC = 0.643 and morbidity (P = 0.000, AUC = 0.763, comparable to that of APACHE-IV score. PCT values on admission did not show significant association with mortality, but correlated well with morbidity and prolonged hospital length of stay (AUC = 0.616, P = 0.045. Conclusion: The current study demonstrated a good predictive value of NTproBNP, in terms of mortality and morbidity comparable to that of APACHE-IV score. Procalcitonin, however, was found to have doubtful prognostic importance. These findings need to be confirmed in a prospective larger study.

  19. Deletion of PTH rescues skeletal abnormalities and high osteopontin levels in Klotho-/- mice.

    Directory of Open Access Journals (Sweden)

    Quan Yuan

    Full Text Available Maintenance of normal mineral ion homeostasis is crucial for many biological activities, including proper mineralization of the skeleton. Parathyroid hormone (PTH, Klotho, and FGF23 have been shown to act as key regulators of serum calcium and phosphate homeostasis through a complex feedback mechanism. The phenotypes of Fgf23(-/- and Klotho(-/- (Kl(-/- mice are very similar and include hypercalcemia, hyperphosphatemia, hypervitaminosis D, suppressed PTH levels, and severe osteomalacia/osteoidosis. We recently reported that complete ablation of PTH from Fgf23(-/- mice ameliorated the phenotype in Fgf23(-/-/PTH(-/- mice by suppressing serum vitamin D and calcium levels. The severe osteomalacia in Fgf23(-/- mice, however, persisted, suggesting that a different mechanism is responsible for this mineralization defect. In the current study, we demonstrate that deletion of PTH from Kl(-/- (Kl(-/-/PTH(-/- or DKO mice corrects the abnormal skeletal phenotype. Bone turnover markers are restored to wild-type levels; and, more importantly, the skeletal mineralization defect is completely rescued in Kl(-/-/PTH(-/- mice. Interestingly, the correction of the osteomalacia is accompanied by a reduction in the high levels of osteopontin (Opn in bone and serum. Such a reduction in Opn levels could not be observed in Fgf23(-/-/PTH(-/- mice, and these mice showed sustained osteomalacia. This significant in vivo finding is corroborated by in vitro studies using calvarial osteoblast cultures that show normalized Opn expression and rescued mineralization in Kl(-/-/PTH(-/- mice. Moreover, continuous PTH infusion of Kl(-/- mice significantly increased Opn levels and osteoid volume, and decreased trabecular bone volume. In summary, our results demonstrate for the first time that PTH directly impacts the mineralization disorders and skeletal deformities of Kl(-/-, but not of Fgf23(-/- mice, possibly by regulating Opn expression. These are significant new perceptions into

    Infants with Down syndrome (DS) are at risk of developing a transient myeloproliferative disorder during the neonatal period, known as transient abnormal myelopoiesis (TAM). It is characterized by clonal myeloproliferation and is typically self-limiting. However, TAM can be a life-threatening disorder, when complicated by liver fibrosis. Here, we evaluated cytokine profiles in two male DS infants having TAM with or without liver dysfunction. The first patient, Patient 1, had hyperleukocytosis with cholestatic liver dysfunction, coagulopathy, and increased counts of blasts and was treated with exchange transfusion (ExT) due to the serious general condition. In Patient 1, serum interleukin (IL)-8 and plasma transforming growth factor (TGF)-β1 levels were markedly elevated before ExT (1,518.2 pg/mL and 17,635 pg/mL, respectively). After ExT, serum IL-8 and plasma TGF-β1 levels decreased to 40.7 pg/mL and 6,847 pg/mL, respectively. However, Patient 1 died on day 56 due to cholestatic liver dysfunction; namely, this patient represents fatal TAM. The second patient, Patient 2, had hyperleukocytosis with increased counts of blasts without liver dysfunction and was treated with cytarabine. In Patient 2, plasma TGF-β1 levels, but not plasma IL-8, were elevated (9,068 pg/mL and 28 pg/mL, respectively). Patient 2 was discharged on day 47. In summary, plasma TGF-β1 levels were elevated in the two DS infants with TAM, regardless of the presence or absence of hepatic fibrosis. Importantly, fatal TAM is assoicated with the elevated serum level of IL-8. We thus propose that IL-8 may be involved in the pathogenesis of liver fibrosis. PMID:27546516

  1. Elevated levels of plasma phenylalanine in schizophrenia: a guanosine triphosphate cyclohydrolase-1 metabolic pathway abnormality?

    Directory of Open Access Journals (Sweden)

    Olaoluwa Okusaga

    Full Text Available BACKGROUND: Phenylalanine and tyrosine are precursor amino acids required for the synthesis of dopamine, the main neurotransmitter implicated in the neurobiology of schizophrenia. Inflammation, increasingly implicated in schizophrenia, can impair the function of the enzyme Phenylalanine hydroxylase (PAH; which catalyzes the conversion of phenylalanine to tyrosine and thus lead to elevated phenylalanine levels and reduced tyrosine levels. This study aimed to compare phenylalanine, tyrosine, and their ratio (a proxy for PAH function in a relatively large sample of schizophrenia patients and healthy controls. METHODS: We measured non-fasting plasma phenylalanine and tyrosine in 950 schizophrenia patients and 1000 healthy controls. We carried out multivariate analyses to compare log transformed phenylalanine, tyrosine, and phenylalanine:tyrosine ratio between patients and controls. RESULTS: Compared to controls, schizophrenia patients had higher phenylalanine (p<0.0001 and phenylalanine: tyrosine ratio (p<0.0001 but tyrosine did not differ between the two groups (p = 0.596. CONCLUSIONS: Elevated phenylalanine and phenylalanine:tyrosine ratio in the blood of schizophrenia patients have to be replicated in longitudinal studies. The results may relate to an abnormal PAH function in schizophrenia that could become a target for novel preventative and interventional approaches.

  2. Use of procalcitonin for the differential diagnosis of fever in cancer patients: an observational study

    Full Text Available Fever often occurs in cancer patients and the possibility of having a reliable marker for the differential etiological diagnosis is desirable. The aim of this study was to investigate the eligibility of the use of procalcitonin (PCT in hemato-oncological patients for the differential diagnosis of fever. We prospectively enrolled 98 cancer patients and divided them into two groups: those with active disease and those with non-active disease. Procalcitonin was dosed at Time 0 (recruitment and at the onset of fever. On enrollment, PCT values were 0.1 ng/mL in 83% patients with active disease, and lower than 0.5 ng/mL in 23%, which is usually considered not suggestive of bacterial infection. Four percent of patients had values over 0.5 ng/mL and these were mainly patients with neuroendocrine tumors or affiliates. On enrollment, there were also no statistically significant differences in PCT values between the two groups of patients. This showed that active cancer is unable by itself to change PCT levels. In the active disease group, 21 episodes of fever due to bacterial infection were registered, and in all of them an increase in PCT values was observed. This demonstrates the ability of PCT to detect an infection-induced fever in cancer patients. Procalcitonin concentrations are not significantly altered by active neoplastic disease. On the contrary, in the course of fever due to a bacterial infection, PCT values increase and can, therefore, be considered a useful tool in the differential diagnosis between infection-induced fever and drug-related or tumor associated-fever. Procalcitonin may be a useful marker of bacterial infection even in cancer patients.

    Full Text Available Objective: Quantitation of D-dimer level during a sickling crisis and its correlation with other clinical abnormalities. Design: Prospective longitudinal study. Setting: Armed Forces Hospital, Southern Region, Kingdom of Saudi Arabia. Patients: Adult patients (12 years and older admitted acutely with a sickle cell crisis who consent to taking part in the study. Candidates may re-participate if they are readmitted with a further acute painful crisis. Results: 36 patients with homozygous sickle cell disease consented to take part in the study. D-dimer levels were raised in 31 (68.9% of 45 episodes of painful crisis of whom 13 had an abnormal chest X-ray. Of those with a normal chest X-ray only one patient had a raised D-dimer level: sensitivity of 92.3%, specificity 40.6%, positive predictive value 38.7% and negative predictive value of 92.9% for an abnormal chest X-ray. Conclusion: D-dimer levels are frequently raised during an acute painful crisis. A normal level has a high negative predictive value for an abnormal chest X-ray.

    Procalcitonin is a sensitive and specific marker of bacterial infection; low results allow clinicians to safely de-escalate antibiotics. This retrospective cohort study aimed to determine the effect of low procalcitonin results on withholding, discontinuing, or de-escalating antibiotics in hospitalized patients at a tertiary care center. Antibiotics were initiated or continued without de-escalation in 55% of patients with low procalcitonin results. Among patients with low procalcitonin result...

    Full Text Available The differentiation of sepsis and systemic bacterial infections from other causes of systemic inflammatory response is crucial from the therapeutic point of view. The clinical signs and symptoms are non-specific and traditional biomarkers like white cell count, erythrocyte sedimentation rate and C-reactive protein are not sufficiently sensitive or specific to guide therapeutic decisions. Procalcitonin (PCT is considered a reliable marker for the diagnosis and prognosis of moderate to severe bacterial infections, and it has also been evaluated to guide the clinicians in the rational usage of antibiotics. This review describes the diagnostic and prognostic role of PCT as a biomarker in various clinical settings along with the laboratory aspects and its usefulness in risk stratification and antibiotic stewardship.

    Calcitonin (CT), the major biochemical marker in medullary thyroid carcinoma (MTC) is prone to in vitro instability and suffers from scarcity of clinical laboratory platforms. Procalcitonin (PCT), the precursor of CT, free of these shortcomings, has been reported as a potential MTC marker. The aim of this study was to assess the negative predictive value (NPV) of PCT as a first-line marker in MTC. 476 serum samples referred to our laboratory for CT measurements were analyzed for PCT. NPVs of PCT were assessed at 3 cut-offs (0.05, 0.10 and 0.15 ng/mL) and the diagnosis of MTC was based on CT levels. PCT and CT levels were correlated (r=0.7554 for CT levels above 10 pg/mL, n=66). Accepting the CT cut-off based on the upper reference limit the NPV of PCT were 98.1% (0.05 ng/mL), 96.3% (0.10 ng/mL) and 95.4% (0.15 ng/mL) respectively. For a CT cut-off of 100 pg/mL the NPVs of PCT were 100% for all PCT thresholds. Serum PCT has a strong NPV and could be a good candidate for a first-line screening test to exclude MTC in patients with suspicious thyroid nodules or suggestive symptoms. Larger prospective studies are necessary to confirm our results. PMID:26806393

    Diagnosis of infections in cancer patients is usually problematic since differentiating between infection and fever of unknown origin is often a considerable clinical challenge. In general, increase concentration of blood procalcitonin (PCT) is associated with severe bacterial infection. PCT with an optimal cutoff level of 0.5 ng/mL seems to be the most helpful biochemical parameter in detecting severe infections, mainly bloodstream infection, in patients with hematological cancers. In all clinical situations, the elevated level of PCT should be carefully analyzed, always with a thorough physical examination and an appropriate microbiological assessment. PMID:26858528

    Full Text Available Aim. The aim of our study is to compare the potential usefulness of procalcitonin with the CRP as a diagnostic marker of pediatric diseases and to define the diagnostic accuracy and relation with the inflammation etiology and severity of procalcitonin. Methods. The analysis focused on a sample of 141 children, hospitalized for fever with bacterial, viral or inflammatory etiology, studied at the time of admission in the Hospital, and after defervescence. The sensitivity, the specificity, the positive and negative predictive value have been calculated for the both tests, explained above. Results. The diagnostic accuracy of procalcitonin is the same as the one of PCR in all cases. The result of the test has been positive in 85,7% of the serious infections and has been useful to identifiy the etiology of infections in almost 2/3 of patients. Conclusion. Procalcitonin seems to be a promising marker of infections because of its following features: a larger contribution in the monitoring phase (fast positivization and normalization; the diagnostic accuracy and a good correlation with the etiology and the severity of infections. Nonetheless, the routine use of procalcitonin is not recommended in the light of

    Full Text Available Despite several consensus conferences, the criteria for the definition of sepsis are still considered too sensitive and insufficiently specific. The traditional clinical signs of infection and routine laboratory tests used to diagnose bacterial infection and sepsis lack diagnostic accuracy and can be misleading, particularly in patients with immunodeficiencies. The problems with sepsis definitions and diagnoses are indications of the need to focus on biochemical mediators capable not only of distinguishing the inflammatory response to infection from other types of inflammation, but also of indicating the severity and prognosis of the disease. Thus, physicians need an early and rapid marker for detecting bacterial infection and distinguishing it from viral infection. Several studies revealed that elevated procalcitonin (PCT levels in human blood could be detected in cases of sepsis and bacterial infection. PCT is a protein that can act as a hormone and a cytokine. It can be produced by several cell types and many organs in response to proinflammatory stimuli, particularly bacterial infection. It provides a rapid diagnostic test, available at the patient's bedside, and its half-life is suitable for daily monitoring of the disease progress.

    Abstract Several studies have investigated the diagnostic accuracy of procalcitonin (PCT) levels in blood or cerebrospinal fluid (CSF) in bacterial meningitis (BM), but the results were heterogeneous. The aim of the present study was to ascertain the diagnostic accuracy of PCT as a marker for BM detection. A systematic search of the EMBASE, Scopus, Web of Science, and PubMed databases was performed to identify studies published before December 7, 2015 investigating the diagnostic accuracy of PCT for BM. The quality of the eligible studies was assessed using the revised Quality Assessment for Studies of Diagnostic Accuracy method. The overall diagnostic accuracy of PCT detection in CSF or blood was pooled using the bivariate model. Twenty-two studies involving 2058 subjects were included in this systematic review and meta-analysis. The overall specificities and sensitivities were 0.86 and 0.80 for CSF PCT, and 0.97 and 0.95 for blood PCT, respectively. Areas under the summary receiver operating characteristic curves were 0.90 and 0.98 for CSF PCT and blood PCT, respectively. The major limitation of this systematic review and meta-analysis was the small number of studies included and the heterogeneous diagnostic thresholds adopted by eligible studies. Our meta-analysis shows that PCT is a useful biomarker for BM diagnosis. PMID:26986140

  3. Analysis of serum lipid profiles, metal ions and thyroid hormones levels abnormalities in - thalassaemic children of Bangladesh

    International Nuclear Information System (INIS)

    Objective: To assess the serum lipid profile of cardiovascular disease free male and female children with - thalassaemia. Levels of zinc, copper and magnesium in the serum were also determined along with the Thyroid profile. Methods: From January to December 2007, we enrolled 121 consecutive patients with -thalassaemia that visited The Thalassaemia Center at Dhaka Shishu (Children) Hospital, Bangladesh every month for routine examinations. Fasting blood lipid levels were measured in all participants. Zinc, Copper and Magnesium levels in serums were determined. Thyroid function was also assessed by evaluating T3, T4 and TSH levels. Results: Of the 121 patients, 65 were males (10.14 +- 3.91 years) and 56 were females (9.08 +- 4.32 years). Data analysis revealed that 2.0% males and 4.35% females had high total serum cholesterol, and 28.57% males and 21.74% females had high triglyceride levels. In addition, mean HDL-cholesterol levels were 21.14 +- 5.82 mg/dl in males and 21.17 +- 6.02 mg/dl in females; total-cholesterol to HDL-cholesterol ratios were 5.47 +- 1.66 and 5.96 +- 2.81 in males and females respectively. About 60% patients showed low serum level of Zn and Cu. Hypothyroidism was detected in 30% patients and 23% patients had abnormal experimental values of all the study parameters. Conclusions: The majority of the patients had blood lipid levels (by the exception of HDL-cholesterol) within the normal range, and consequently the prevalence of lipid abnormalities was much lower as compared to the general population of the same age. Interestingly, the total-cholesterol to HDL-cholesterol ratio was high in our patients, and may underline the importance of this index for the prognosis of future cardiac events in these patients. The serum Zn and Cu levels were low in most of the patients which may cause some metabolic abnormalities in future. Most of the patients also showed hypothyroidism indicating the presence of endocrine complications. (author)

    Multivitamin preparations are commonly administered to regular dialysis treatment (RDT) patients. Serum Vitamin A was measured in 72 patients on RDT. Elevated serum Vitamin A levels (102.29 +/- 26.95 microgram/dl [3.57 +/- 0.94 mumoles/l]) were found in the dialysis population (normal 40.98 +/- 6.71 microgram/dl [1.43 +/- 0.23 mumoles/l]; P less than 0.0005). Serum Vitamin A levels increased with duration (months) of dialysis but not with frequency of dialysis (twice or thrice weekly). Patients taking a VitaminA-containing multivitamin preparation had higher serum Vitamin A levels than those on a non-Vitamin A supplemented diet. Bilaterally nephrectomized patients had the highest serum Vitamin A levels while patients with obstructive uropathy had the lowest levels. Serum Vitamin A levels did not correlate with symptoms of uremia. Positive correlations were found with serum levels of calcium, cholesterol and triglycerides. Patients receiving a Vitamin A supplement had higher serum cholesterol levels than non-supplemented patients. Vitamin A might be a factor in the high incidence of cardiovascular disease in RDT patients. We therefore advise discontinuing the long-term administration of Vitamin A-containing multivitamin supplements to patients on RDT. PMID:527272

    The infections very often complicate the course of autoimmune rheumatic diseases. In diagnostic of septic complications in rheumatic patients the new biomarkers of infections can have a decisive importance. The procalciotonine test is one of them. The issue was to evaluate the diagnostic informativity of this test. The sample included 93 patients. The examination was applied to 65 patients with rheumatic diseases. Among them, 13 patients had bacterial infections. The group consisted of 33 patients with rheumatoid arthritis, 11 patients with systemic lupus erythematous, 6 patients with systemic angiitis, and 15 patients with other rheumatic diseases. The comparative group included 27 patients of cardio-therapeutic profile and 8 of these patients had bacterial infections. The procalcitonine test was applied with quantitative electrochemiluminescent technique. In patients with rheumatoid arthritis the mean levels of procalciotonine test consisted 0.10 +/- 0.13 ng/ml; with systemic lupus erythematous--0.08 +/- 0.06 ng/ml; with systemic angiitis--0.22 +/- 0.2 ng/ml; with other rheumatic diseases--0.12 +/- 0.15 ng/ml; of cardio-therapeutic profile without infections--0.08 +/- 0.06 ng/vl/ With threshold of procalcitonine test higher than 0.5/ml the sensitivity to diagnostic of infections consisted of 58%, specificity--94% in the group with rheumatic diseases. The procalciotonine test in case of no infection process with values higher than 0.5 ng/ml was detected in three patients. The evaluation of dependence of sensitivity and specificity for procalciotonine test and C-reactive protein the area under curve of procalcitonine test was larger in patients with rheumatic diseases (0.85 against 0.79) and in patients of cardio-therapeutic profile (0.92 against 0.90). The quantitative procalcitonine test is the best technique to detect septic complications in rheumatic patients. PMID:23807991

    Introduction Severe sepsis and septic shock are advanced clinical conditions representing the patient's response to infection and having a variable but high mortality rate. Early evaluation of sepsis stage and choice of adequate treatment are key factors for survival. Some study results suggest the necessity of daily procalcitonin (PCT) monitoring because of its prognostic and discriminative value. Material and methods An observational and prospective study was conducted to evaluate the prognostic and discriminative value of PCT kinetics in comparison to PCT absolute value measurements. In a group of 50 intensive care unit patients with diagnosis of severe sepsis or septic shock, serum PCT measurements were performed on admission, and on the 2nd, 3rd and 5th day of therapy. The level of PCT was determined with a commercially available test according to the manufacturer's protocol. Results The kinetics of PCT assessed by ΔPCT was statistically significant in the survivors vs. the non-survivors subgroup (ΔPCT3/1, p = 0.022; ΔPCT5/1, p = 0.021). ΔPCT has no statistical significance in the severe sepsis and septic shock subgroups for all analyzed days. Only the 5th day PCT level was significantly higher in the non-survivors vs. survivors group (p = 0.008). The 1st day PCT level in the severe sepsis vs. septic shock group has a discriminative impact (p = 0.009). Conclusions According to the results, single serum PCT measurement, regardless of absolute value, has a discriminative impact but no prognostic significance, during the first 2 days of therapy. The PCT kinetics is of prognostic value from the 3rd day and is of earlier prognostic significance in comparison to changes in the patient's clinical condition evaluated by SOFA score kinetics.

    The aim of this study was to evaluate procalcitonin as an adjunct to diagnose bacterial infections in older patients. One hundred seventy-two patients admitted to an acute-care geriatric unit during a 6-month period were prospectively included, 39 of them with an invasive bacterial infection. The best cut-off value to rule in a bacterial infection was 0.51 microg/l with sensitivity 64% and specificity 94%. The best cut-off value to rule out a bacterial infection was 0.08 microg/l with sensitivity 97% and specificity 20%. Procalcitonin was inconclusive (between 0.08 and 0.51 microg/l) for 112 admissions. Procalcitonin over 0.51 microg/l was useless 22 times out of 33 (infection already ruled in on clinical grounds) and misleading in eight of the 11 remaining cases (no infection). Procalcitonin below 0.08 microg/l was useless 23 times out of 27 (infection already ruled out on clinical grounds) and misleading in one of the four remaining cases (infection). Despite a good overall diagnostic accuracy, the clinical usefulness of PCT to diagnose invasive bacterial infections in elderly patients hospitalized in an acute geriatric ward appears to be very limited.

    Full Text Available Sepsis can sometimes be difficult to substantiate, and its distinction from non-infectious conditions in critically ill patients is often a challenge. Serum procalcitonin (PCT assay is one of the biomarkers of sepsis. The present study was aimed to assess the usefulness of PCT assay in critically ill patients with suspected sepsis. The study included 40 patients from the intensive care unit with suspected sepsis. Sepsis was confirmed clinically and/or by positive blood culture. Serum PCT was assayed semi-quantitatively by rapid immunochromatographic technique (within 2 hours of sample receipt. Among 40 critically ill patients, 21 had clinically confirmed sepsis. There were 12 patients with serum PCT ≥10 ng/ml (8, blood culture positive; 1, rickettsia; 2, post-antibiotic blood culture sterile; and 1, non-sepsis; 7 patients with PCT 2-10 ng/ml (4, blood culture positive; 1, falciparum malaria; 2, post-antibiotic blood culture sterile; 3 patients with PCT of 0.5 to 2 ng/ml (sepsis in 1 patient; and 18 patients with PCT < 0.5 ng/ml (sepsis in 2 patients. Patients with PCT ≥ 2 ng/ml had statistically significant correlation with the presence of sepsis (P<0.0001. The PCT assay revealed moderate sensitivity (86% and high specificity (95% at a cut-off ≥ 2 ng/ml. The PCT assay was found to be a useful biomarker of sepsis in this study. The assay could be performed and reported rapidly and provided valuable information before availability of culture results. This might assist in avoiding unwarranted antibiotic usage.

    Summary The goal of this study was to analyse plasma procalcitonin (PCT) concentrations during infectious events of burns in ICU. We conducted a prospective, observational study in a 20-bed Burn Intensive Care Unit in Tunisia. A total of 121 patients admitted to the Burn ICU were included in our study. Serum PCT was measured over the entire course of stay in patients with predictive signs of sepsis according to the Americain Burn Association Criteria for the presence of infection. Patients were assigned to two groups depending on the clinical course and outcome: Group A = non septic patients; Group B = septic patients. A PCT cutoff value of 0,69 ng/ml for sepsis prediction was associated with the optimal combination of sensitivity (89%), specificity (85%), positive predictive value (82%) and negative predictive value (88%). Serum procalcitonin levels can be used as an early indicator of septic complication in patients with severe burn injuries as well as in monitoring the response to antimicrobial therapy.

    Purpose. To investigate whether absolute value of procalcitonin (PCT) or the change (delta-PCT) is better indicator of infection in intensive care patients. Materials and Methods. Post hoc analysis of a prospective observational study. Patients with suspected new-onset infection were included in whom PCT, C-reactive protein (CRP), temperature, and leukocyte (WBC) values were measured on inclusion (t 0) and data were also available from the previous day (t -1). Based on clinical and microbiological data, patients were grouped post hoc into infection- (I-) and noninfection- (NI-) groups. Results. Of the 114 patients, 85 (75%) had proven infection. PCT levels were similar at t -1: I-group (median [interquartile range]): 1.04 [0.40-3.57] versus NI-group: 0.53 [0.16-1.68], p = 0.444. By t 0 PCT levels were significantly higher in the I-group: 4.62 [1.91-12.62] versus 1.12 [0.30-1.66], p = 0.018. The area under the curve to predict infection for absolute values of PCT was 0.64 [95% CI = 0.52-0.76], p = 0.022; for percentage change: 0.77 [0.66-0.87], p value for delta-PCT to indicate infection was 0.76 ng/mL (sensitivity 80 [70-88]%, specificity 86 [68-96]%). Neither absolute values nor changes in CRP, temperature, or WBC could predict infection. Conclusions. Our results suggest that delta-PCT values are superior to absolute values in indicating infection in intensive care patients. This trial is registered with ClinicalTrials.gov identifier: NCT02311816.

    The abnormal conditions to which blood is subjected during cardiopulmonary bypass (CPB) trigger an activation of the inflammatory response and cause pulmonary dysfunction. It has been suggested that high-volume, zero-balanced ultrafiltration (ZBUF) facilitates clearance of inflammatory mediators and improves post-operative pulmonary function. Procalcitonin, a newly discovered inflammatory mediator, has been found to be increased after CPB and has been proven to be an appropriate parameter for predicting pulmonary dysfunction secondary to CPB. The aim of this study was to investigate the effects of zero-balanced ultrafiltration (ZBUF) on procalcitonin (PCT) and respiratory function of infants with Tetralogy of Fallot (TOF) after CPB. Twenty infants with TOF undergoing open-heart total surgical correction were randomly assigned to two groups. The trial group was given ZBUF (50 ml/kg) and conventional ultrafiltration (CUF), while the control group was given CUF only. Plasma PCT and pulmonary function were monitored and compared between the two groups before the operation (T1), before rewarming (T2), at the end of the operation (T3), and at 12 h, 24 h and 48 h after the operation (T4-T6). PCT was decreased in the trial group between 12 h and 48 h post-operatively, but the differences did not reach statistical significance. The trial group's pulmonary compliance was higher at 12 h post-operatively (p 0.05). Intubation time was shorter in the trial group (P < 0.01). A positive correlation was found between peak PCT concentration and intubation time. ZBUF appeared to improve ventilation and shorten intubation time. The improved respiratory function may be due to the lower plasma PCT. PMID:18416220

    Renal vein thrombosis (RVT) in neonates is a rare condition of low mortality but significant morbidity due to renal impairment.We report the case of a male term newborn with left RVT and elevated serum factor VIII (FVIII).The main symptoms of the patient and the important clinical findings: prompt diagnosis of RVT was possible because the classic clinical presentation of macroscopic hematuria, thrombocytopenia, and palpable flank mass were present in this newborn infant.The main diagnoses: finally, the reason of RVT was established when the infant was 3 months of age: the increased level of FVIII was confirmed. We discuss the diagnosis, therapy, and outcome of the patient and compare with the literature.Therapeutics interventions: however, despite anticoagulant therapy the left kidney developed areas of scarring and then atrophy.Conclusions and outcomes: Prothrombotic defects should be considered in all patients with perinatal RVT. Elevated factor VIII as a reason of RVT in neonatal period is particularly rare. Given a poor renal outcome in children associated with elevated levels of factor VIII, consideration could be given to more aggressive antithrombotic therapy in such cases.

    Introduction: Urinary tract infection (UTI) is one of the most common bacterial infections in children that can be associated with renal parenchymal injuries and late scars. Dimercaptosuccinic acid (DMSA) renal scan is known as golden standard for detecting acute pyelonephritis (APN) that has a lot of difficulties and limitations. Objectives: we designed this study the accuracy of one inflammatory marker, serum procalcitonin (PCT) to identify as an early predictor of renal injuries. Patients and Methods: A prospective study was carried out in 95 patients who admitted in the hospital with the first febrile UTI. Serum PCT of all patients was measured; sensitivity, specificity, positive and negative predictive value (PPV and NPV) of this marker was analyzed compared to DMSA scan. P value <0.05 was taken as significant. Results: In total, 79 females and 16 males were investigated. There are 42 cases in group 1 with normal DMSA scan and 53 patients in group two with renal parenchymal injuries in their scans. Mann-Whitney test showed a meaningful relation between the two groups regarding PCT level (P<0.0001). Sensitivity, specificity, PPV and NPV of PCT reported in optimum cut off were 70%, 88.1%, 88.1% and 70%, respectively. The positive likelihood ratio (PLR) of PCT test was 5.8. Conclusion: In the current survey, PCT was the eligible inflammatory marker to predict renal parenchymal injuries in children with proper sensitivity, specificity, PPV and NPV that play also a pivotal role in the children aged less than 24 months, although, more studies should be undertaken to confirm.

    This prospective cohort study aimed to analyze the association between serum ferritin levels and the risk of abnormal glucose metabolism (AGM) in Southwestern Chinese population. The 383 subjects who are aged ≥20 years and free of AGM at baseline between in 2007 and in 2008 were included in Southwestern China, and their baseline serum ferritin levels were measured. Among these subjects, 140 subjects were developed into AGM during the follow-up (2008-2012). In logistic regression models, the relative risk in the top versus that in the lowest quartile of serum ferritin levels was 2.86 (p = 0.013) in females and 3.50 (p = 0.029) in males after adjusting the age, gender, family history of diabetes, current smoking, and alcohol; however, serum ferritin levels were not significantly associated with incident of AGM after controlling for metabolic factors (waist circumference, systolic pressure (SBP), triglyceride (TG), and homeostasis model assessment formula insulin resistance (HOMA-IR)). Elevated serum ferritin levels are associated with AGM but not an independent risk factor. PMID:26073512

    Full Text Available Procalcitonin (PCT has emerged as a marker of infection, a frequent complication in hemodialysis (HD. We analyzed PCT levels in chronic non-acutely infected HD subjects, assessed its correlation with inflammatory and nutritional markers and propose a PCT reference value for non-infected HD patients.In an observational cross-sectional study, 48 chronic HD patients and 36 controls were analyzed. Variables: age, gender, time on HD; diabetes; vascular access, PCT, C-reactive protein (CRP, albumin, malnutrition inflammatory score (MIS, hematocrit, leukocyte count, and body mass index (BMI. Subsequently, control (G1, n = 36, 43% vs. non-infected patients (G2, n = 48, 57% groups were compared. In control subjects (G1, age: 54.3 ± 13.7 years, range (r: 30-81; males: 19 (53%; median PCT 0.034 ng/ml (r: 0.02-0.08; median CRP 0.80 mg/dl (r: 0.36-3.9; p95 PCT level: 0.063 ng/ml. In G2, age: 60.2 ± 15.2 years; males 32 (67%, time on HD: 27.0 ± 24.4; diabetics: 19 (32%; median PCT: 0.26 ng/ml (r: 0.09-0.82; CRP: 1.1 mg/dl (r: 0.5-6.2; p95 PCT level: 0.8 ng/ml. In control subjects, PCT and CRP were significantly lower than in G2: PCT: 0.034 vs. 0.26 ng/ml, p = 0.0001; CRP: 0.8 vs. 1.1 mg/dl, p = 0.0004. PCT-CRP correlation in G2: ρ = 0.287, p = 0.048. PCT and CRP concentrations are elevated in chronic non-acutely infected HD subjects, independently of infection, diabetes and vascular access. A p95 PCT level of 0.8 ng/ml may be considered as the upper normal reference value in non-acutely infected HD subjects. The PCT cut-off level in HD is yet to be determined in HD.

    In this study, we aimed to determine serum adrenomedullin levels and compare them with levels of C-reactive protein (CRP) and procalcitonin (PCT). Cancer patients aged 0-18 years who experienced febrile neutropenia attacks were included in the study. Adrenomedullin, CRP, and PCT were analyzed at admission, day 3, and days 7-10 later. Fifty episodes of febrile neutropenia that developed in 37 patients were analyzed in this study. The mean age of the patients was 7.5 ± 4.7 (1-18) years. The patients had leukemia (73%), solid tumors (19%), and lymphoma (8%). The percentages of the patients in the clinically documented infection (CDI), fever of unknown origin (FUO), sepsis, and microbiological documented infection (MDI) categories were 34%, 34%, 20%, and 12%, respectively. During the study period, four patients were lost. In the MDI group, adrenomedullin levels on day 3 were significantly higher than those in the CDI and FUO groups. PCT levels were significantly higher in the sepsis group than those in the CDI group at admission, day 3, and days 7-10. In the sepsis group, PCT levels on days 7-10 days were significantly higher than those in the sepsis group. PCT values from the deceased patients on days 7-10 were significantly higher than those from patients who survived. CRP levels did not differ significantly among the febrile neutropenia groups. First, in our study, adrenomedullin was used as a biomarker in the febrile neutropenia episodes of children with cancer. Among adrenomedullin, CRP, and PCT, procalcitonin demonstrates the highest correlation with the severity of infection.

    Full Text Available Urinary tract infections (UTIs are the most common source of bacterial infections among young febrile children. Accurate diagnosis of acute pyelonephritis (APN and vesicoureteral reflux (VUR is important because of their association with renal scarring, leading in the cases to long-term complications. However, the gold standard examinations for both are either DMSA scan (for APN and scar or cystography (for VUR and present limitations (feasibility, pain, cost, etc.. Procalcitonin, a reliable marker of bacterial infections, was demonstrated to be a good predictor of both renal parenchymal involvement in the acute phase and late renal scars. Furthermore, it was also found to be associated with high-grade VUR and was the key tool of a clinical decision rule to predict high-grade VUR in children with a first UTI. Therefore, procalcitonin may certainly be found playing a role in the complex and still debated picture of which examination should be performed after UTI in children.

    2014-09-01

    We evaluated whether procalcitonin (PCT) might aid diagnosing serious bacterial infections in a general pediatric intensive care unit population. Two-hundred and one patients accounted for 332 PCT samples. A PCT ≥1.45 ng/mL had a positive predictive value of 30%, a negative predictive value of 93% and a sensitivity of 72% and a specificity of 75%. These data suggest PCT can assist in identifying patients without serious bacterial infections and limit antimicrobial use.

    The day the wonder drugs, antibiotics, were available for cure to humans; dramatic rise of average life expectancy has been recorded compared to past. However, disease-causing microbes that have developed resistance to antibiotics are an increasing public health problem. Recently, superbug emergence was reported in some countries including India. One of the reasons quoted was misuse of antibiotics. Clinical signs and symptoms of infection often do not point towards the etiology. The dilemma occurs as diagnosis of sepsis is difficult because of nonspecificity of clinical signs and symptoms, and frequent overlapping of symptoms with other noninfectious causes of systemic inflammation. Key for improving survival rates lies in early diagnosis and treatment. Serum procalcitonin (PCT) levels measuring in sick patients during infection may be valuable in diagnosing the conditions, and its changing levels have some prognostic value too. PMID:24083140

    Cervical cancer is caused by infection with high risk human papillomavirus (HR-HPV). Inducible nitric oxide synthase (iNOS), a soluble factor involved in chronic inflammation, may modulate cervical cancer risk among HPV infected women. The aim of the study was to measure and correlate plasma nitrite/nitrate levels with tissue specific expression of iNOS mRNA among women with different grades of cervical lesions and cervical cancer. Tissue biopsy and plasma specimens were collected from 120 women with cervical neoplasia or cancer (ASCUS, LSIL, HSIL and invasive cancer) and 35 women without cervical abnormalities. Inducible nitric oxide synthase (iNOS) mRNA from biopsy and plasma nitrite/nitrate levels of the same study subjects were measured. Single nucleotide polymorphism (SNP) analysis was performed on the promoter region and Ser608Leu (rs2297518) in exon 16 of the iNOS gene. Differences in iNOS gene expression and plasma nitrite/nitrate levels were compared across disease stage using linear and logistic regression analysis. Compared to normal controls, women diagnosed with HSIL or invasive cancer had a significantly higher concentration of plasma nitrite/nitrate and a higher median fold-change in iNOS mRNA gene expression. Genotyping of the promoter region showed three different variations: A pentanucleotide repeat (CCTTT) n, -1026T > G (rs2779249) and a novel variant -1153T > A. These variants were associated with increased levels of plasma nitrite/nitrate across all disease stages. The higher expression of iNOS mRNA and plasma nitrite/nitrate among women with pre-cancerous lesions suggests a role for nitric oxide in the natural history of cervical cancer. PMID:26435258

    Full Text Available Abstract Background The pregnancy hormone human chorionic gonadotropin (hCG and its free subunits (hCG alpha, hCG beta are produced in the male reproductive tract and found in high concentrations in seminal fluid, in particular hCG alpha. This study aimed to elucidate changes in peptide hormone profiles in patients showing abnormal semen analyses and to determine the genuineness of the highly abundant hCG alpha. Methods Seminal plasma was obtained from 45 male patients undergoing semen analysis during infertility workups. Comprehensive peptide hormone profiles were established by a panel of immunofluorometric assays for hCG, hCG alpha, hCG beta and its metabolite hCG beta core fragment, placental lactogen, growth hormone and prolactin in seminal plasma of patients with abnormal semen analysis results (n = 29 versus normozoospermic men (n = 16. The molecular identity of large hyperglycosylated hCG alpha was analyzed by mass-spectrometry and selective deglycosylation. Results hCG alpha levels were found to be significantly lower in men with impaired semen quality (1346 +/- 191 vs. 2753 +/- 533 ng/ml, P = 0.022. Moreover, patients with reduced sperm count had reduced intact hCG levels compared with normozoospermic men (0.097 +/- 0.022 vs. 0.203 +/- 0.040 ng/ml, P = 0.028. Using mass-spectrometry, the biochemical identity of hCG alpha purified from seminal plasma was verified. Under non-reducing conditions in SDS-PAGE, hCG alpha isolated from seminal plasma migrated in a manner comparable with large free hCG alpha with an apparent molecular mass (Mr, app of 24 kDa, while hCG alpha dissociated from pregnancy-derived holo-hCG migrated at approximately 22 kDa. After deglycosylation with PNGase F under denaturing conditions, all hCG alpha variants showed an Mr, app of 15 kDa, indicating identical amino acid backbones. Conclusions The findings indicate a pathophysiological relevance of hCG, particularly its free alpha subunit, in spermatogenesis. The

    Full Text Available Cross-sectional studies suggest associations between abnormal lipid levels and prevalence of low back pain (LBP, but it is not known if there is any causal relationship.The objective was to determine, in a population-based prospective cohort study, whether there is any relation between levels of total cholesterol, high density lipoprotein (HDL cholesterol and triglycerides and the probability of experiencing subsequent chronic (LBP, both among individuals with and without LBP at baseline.Information was collected in the community-based HUNT 2 (1995-1997 and HUNT 3 (2006-2008 surveys of an entire Norwegian county. Participants were 10,151 women and 8731 men aged 30-69 years, not affected by chronic LBP at baseline, and 3902 women and 2666 men with LBP at baseline. Eleven years later the participants indicated whether they currently suffered from chronic LBP.Among women without LBP at baseline, HDL cholesterol levels were inversely associated and triglyceride levels positively associated with the risk of chronic LBP at end of follow-up in analyses adjusted for age only. Adjustment for the baseline factors education, work status, physical activity, smoking, blood pressure and in particular BMI largely removed these associations (RR: 0.96, 95% CI: 0.85-1.07 per mmol/l of HDL cholesterol; RR: 1.16, 95% CI: 0.94-1.42 per unit of lg(triglycerides. Total cholesterol levels showed no associations. In women with LBP at baseline and men without LBP at baseline weaker relationships were observed. In men with LBP at baseline, an inverse association with HDL cholesterol remained after complete adjustment (RR: 0.83, 95% CI: 0.72-0.95 per mmol/l.Crude associations between lipid levels and risk of subsequent LBP in individuals without current LBP are mainly caused by confounding with body mass. However, an association with low HDL levels may still remain in men who are already affected and possibly experience a higher pain intensity.

    Immediate initiation of hemoperfusion treatment with polymixin B immobilized fiber (PMX-DHP) is a potent strategy to improve hemodynamics in septic patients with critical circulatory failure. However, it is often difficult to accurately and rapidly differentiate between bacterial infections and non-infectious causes of shock in acutely critically-ill patients. Procalcitonin (PCT) measurements may assist in the early identification of bacterial infection/sepsis and determination of severity in such patients. We present two febrile neutropenic (FN) patients who developed severe shock after chemotherapy for hematological malignancies. PCT levels were markedly elevated in both patients (≥ 10 ng/ml), suggesting a high likelihood of bacterial infectious etiology as the cause of their shock, and thus they were promptly treated with PMX-DHP. Measurements of PCT may facilitate targeting of PMX-DHP treatment among FN patients suffering from shock, which may lead to better prognosis.

    Procalcitonin (PCT) levels are commonly used for diagnostic guidance in routine bacterial infections. By contrast, little data are currently available regarding PCT in parasitic diseases, and its role in cases of invasive amoebiasis has not yet been described. For this purpose, 35 adult patients with a proven diagnosis of invasive or digestive amoebiasis were included in a 4-year study period. Serum PCT was retrospectively assessed. Results were analysed with regard to the usual inflammatory biomarkers, like C-reactive protein (CRP). PCT was significantly higher in patients with proven invasive amoebiasis than in digestive amoebiasis (mean value: 4.03 μg/L versus 0.07 μg/L, respectively; P < 0.001), but the SD was greater than with CRP, and the effect was less than that demonstrated in bacterial infections. By contrast, PCT was not shown to be elevated during digestive amoebiasis. PMID:26388549

  20. Procalcitonin Identifies Cell Injury, Not Bacterial Infection, in Acute Liver Failure.

    Full Text Available Because acute liver failure (ALF patients share many clinical features with severe sepsis and septic shock, identifying bacterial infection clinically in ALF patients is challenging. Procalcitonin (PCT has proven to be a useful marker in detecting bacterial infection. We sought to determine whether PCT discriminated between presence and absence of infection in patients with ALF.Retrospective analysis of data and samples of 115 ALF patients from the United States Acute Liver Failure Study Group randomly selected from 1863 patients were classified for disease severity and ALF etiology. Twenty uninfected chronic liver disease (CLD subjects served as controls.Procalcitonin concentrations in most samples were elevated, with median values for all ALF groups near or above a 2.0 ng/mL cut-off that generally indicates severe sepsis. While PCT concentrations increased somewhat with apparent liver injury severity, there were no differences in PCT levels between the pre-defined severity groups-non-SIRS and SIRS groups with no documented infections and Severe Sepsis and Septic Shock groups with documented infections, (p = 0.169. PCT values from CLD patients differed from all ALF groups (median CLD PCT value 0.104 ng/mL, (p ≤0.001. Subjects with acetaminophen (APAP toxicity, many without evidence of infection, demonstrated median PCT >2.0 ng/mL, regardless of SIRS features, while some culture positive subjects had PCT values <2.0 ng/mL.While PCT appears to be a robust assay for detecting bacterial infection in the general population, there was poor discrimination between ALF patients with or without bacterial infection presumably because of the massive inflammation observed. Severe hepatocyte necrosis with inflammation results in elevated PCT levels, rendering this biomarker unreliable in the ALF setting.

    Full Text Available Background and Aim: Urinary tract infection (UTI in children is among the prevalent infections of childhood, which occurs due to growth of bacteria in the urinary tract. The aim of this study was to evaluate the usefulness of procalcitonin (PCT as a reliable marker for distinguishing urinary tract infection (UTI with or without renal parenchyma (cystitis. Materials and Methods: Eighty children, who were suspicious of having UTI and had been referred to Ali Ibne Abitaleb hospital (in Zahedan or pediatric clinics (June 2007- Oct 2009 were included in the study after their urine culture revealed their infection. Besides, their clinical and lab symptoms including erythrocyte sedimentation rate (ESR, C– reactive protein (CRP, serum WBC, and serum procalcitonin (PCT were recorded. The patients were divided into two groups based on their lab clinical symptoms and radio-isotope scans, namely acute pyelonephritis and acute cystitis (lower UTI. Serum procalcitonin was measured in these cases in a semi-quantitative manner. Results: Fifty children with mean age of 4.89±3.50 years were compared with 30 children with mean age of 5.20±3.07 years. ESR, WBC, and PCT were significantly higher in patients with upper UTI (P<0.001 , but CRP was not significantly different in the two groups. PCT, which was semi-quantitatively measured, when lower than 0.5 had a relationship with sensitivity, specificity, positive predictive value, and negative value of 72%, 83.3%, 87.8%, and 64.1% respectively. When PCT was more than 2, the relationship with the mentioned features was 50%, 96.6%, 96.2%, and 53.7%, respectively. The relationships in these two domains can both be assistant in differentiating pyelonephritis from cystitis. Conclusion: PCT was more sensitive and specific for the diagnosis of upper versus lower UTI compared with CRP, and it can be a better marker than CRP for early prediction of febrile pyelonephritis in children.

    Human pregnancy-specific beta-1-glycoprotein (SP1) was assayed retrospectively in stored maternal serum (MS) samples from 82 chromosomally abnormal pregnancies and 377 matched controls. The median MSSP1 concentration in 48 Down's syndrome pregnancies was significantly elevated at 1.17 multiples of the control median (MOM), and significantly reduced (0.5 MOM) in a group of eight cases of unbalanced translocations. There was no significant difference in median SP1 concentrations in cases of trisomy 18, trisomy 13, balanced translocations, or sex chromosome abnormalities. A comparison with human chorionic gonadotrophin results in the same series of samples indicates that SP1 is a less sensitive predictor of Down's syndrome pregnancies. PMID:1387478

    Objective: To study the levels of procalcitonin (PCT) in various inflammatory states seen in an internal medicine department and to evaluate the possible discriminative role of PCT in differentiating bacterial infection from other inflammatory processes. Methods: PCT, C reactive protein (CRP), and white blood cell count (WBC) were measured in patients admitted to the department for fever or biological inflammatory syndrome, or both. The serum of 173 consecutive patients was analysed according to the aetiological diagnosis. The patients were divided into two groups: group I (n=60) with documented bacterial or fungal infection; group II (n=113) with abacterial inflammatory disease. Results: PCT levels were >0.5 ng/ml in 39/60 (65%) patients in group I. In group II, three patients with a viral infection had slightly increased PCT levels (0.7, 0.8, and 1.1 ng/ml) as did two others, one with crystal arthritis and the other with vasculitis (0.7 ng/ml in both cases). All other patients in group II had PCT levels 0.5 ng/ml was taken as the marker of bacterial infection (sensitivity 65%, specificity 96%). PCT values were more discriminative than WBC and CRP in distinguishing a bacterial infection from another inflammatory process. Conclusion: PCT levels only rose significantly during bacterial infections. In this study PCT levels >1.2 ng/ml were always evidence of bacterial infection and the cue for starting antibiotic treatment. PMID:12634233

    Full Text Available Background: The benefits of procalcitonin measurement in neonatal bacteremia/septicemia with suspected nosocomial infection are unclear and unresearched. Aim: The aim of the study was to assess procalcitonin value as an early or first line diagnosis/prognosis for bacterial neonatal septicemic infection in selected critically ill neonates. Patients and Methods: An observational cohort study in a 10-bed intensive care unit was performed. Sixty neonates, with either proven or clinically suspected, but not confirmed, bacterial neonatal septicemic infection were included. Procalcitonin measurements were obtained on the day when the infection was suspected. Neonates with proven septicemic infection were compared to those without. The diagnostic value of procalcitonin was determined through the area under the corresponding receiver operating characteristic curve (AUROCC. In addition, the predictive value of procalcitonin variations preceding the clinical suspicion of infection was also assessed. Results: Procalcitonin was the best early predictor of proven infection in this population of neonates with a clinical suspicion of septicemia (AUROCC = 0.80; 91.6% CI, 0.68-0.91. In contrast, CRP elevation, leukocyte count and fever had a poor predictive value in our population. Conclusion: PCT monitoring could be helpful in the early diagnosis of neonatal septicemic infection in the intensive care unit. Both absolute values and variations should be considered and evaluated in further studies.

    Full Text Available Objectives: The objective of this study was to evaluate any abnormal change in plasma glucose levels in patients treated with L-asparaginase (L-Asp-based chemotherapy regimen in patients of acute lymphoblastic leukemia (ALL. Materials and Methods: This retrospective, hospital-based study was conducted in patients of ALL, admitted to the Clinical Haematology Department of a tertiary care hospital of Odisha from August 2014 to July 2015. Indoor records of 146 patients on multi-centered protocol-841 were evaluated for any alteration in plasma glucose level, time of onset of hypo/hyperglycemia, and persistence of plasma glucose alteration. Results: Twenty-one percent of patients showed abnormal plasma glucose level. Most of these patients developed hypoglycemia and were of lower age group. Most of these patients developed hypoglycemia and were of lower age group, whereas a majority of higher age group patients developed hyperglycemia. In majority of the cases, abnormal glucose developed after three doses of L-Asp. Hypoglycemia subsided whereas hyperglycemia persisted till the end of our observation period. Conclusions: L-Asp produces more incidences of hypoglycemia than hyperglycemia in a good number of ALL patients towards which clinicians should be more vigilant. However, hyperglycemia persists for a longer duration than hypoglycemia.

    Full Text Available Background: Identifying infections early, commencing appropriate empiric antibiotic not only helps gain control early, but also reduces mortality and morbidity. Conventional cultures take about 5 days to identify infections. To identify the infections early biomarker like serum procalcitonin (SPC. Aims: We studied the correlation of an elevated level of SPC and positive culture in elective adult patients undergoing cardiac surgery. Methods: This prospective study was conducted from January to December 2013. SPC was checked in patients showing evidence of sepsis. Simultaneously, relevant culture was also undertaken. Correlation, specificity, and sensitivity of elevated SPC were checked. Results: A total of 819 adult patients were included in the study. 43 of them had signs of infection and SPC levels were checked. Based on the level of SPC criteria, 10 patients were diagnosed as "nil", out of them, 4 had culture-positive infections, 17 were suggested to have "mild infection," 3 out those had culture positivity. None among the eleven patients suggested to have "moderate infection," had a positive culture, and one among the five suggested to have a severe infection had a positive culture. The sensitivity was 50% and the specificity 17%. The positive predictive value was 12% and the negative predictive value 60%. Conclusions: We failed to elicit positive correlation between elevated SPC levels and postoperative infection in cardio surgical patients.

    Full Text Available Abstract Background Tinnitus is an auditory sensation frequently following hearing loss. After cochlear injury, deafferented neurons become sensitive to neighbouring intact edge-frequencies, guiding an enhanced central representation of these frequencies. As psychoacoustical data 123 indicate enhanced frequency discrimination ability for edge-frequencies that may be related to a reorganization within the auditory cortex, the aim of the present study was twofold: 1 to search for abnormal auditory mismatch responses in tinnitus sufferers and 2 relate these to subjective indicators of tinnitus. Results Using EEG-mismatch negativity, we demonstrate abnormalities (N = 15 in tinnitus sufferers that are specific to frequencies located at the audiometrically normal lesion-edge as compared to normal hearing controls (N = 15. Groups also differed with respect to the cortical locations of mismatch responsiveness. Sources in the 90–135 ms latency window were generated in more anterior brain regions in the tinnitus group. Both measures of abnormality correlated with emotional-cognitive distress related to tinnitus (r ~ .76. While these two physiological variables were uncorrelated in the control group, they were correlated in the tinnitus group (r = .72. Concerning relationships with parameters of hearing loss (depth and slope, slope turned out to be an important variable. Generally, the steeper the hearing loss is the less distress related to tinnitus was reported. The associations between slope and the relevant neurophysiological variables are in agreement with this finding. Conclusions The present study is the first to show near-to-complete separation of tinnitus sufferers from a normal hearing control group based on neurophysiological variables. The finding of lesion-edge specific effects and associations with slope of hearing loss corroborates the assumption that hearing loss is the basis for tinnitus development. It is likely that some central

    Full Text Available Microvascular abnormalities are one of the most important causes of persistent diabetic complications. The aim of this study was to compare microvascular changes examined by nailfold capillaroscopy with serum concentrations of soluble E-selectin (sE-selectin and IL-18 in type 1 diabetic patients with and without microangiopathy. Serum levels of sE-selectin and IL-18 were determined by an enzyme-linked immunosorbent assay in 106 patients with type 1 diabetes and in 40 healthy controls. All diabetic patients were evaluated by extensive clinical, laboratory and capillaroscopic studies. Morphological changes were observed by nailfold capillaroscopy in 86 out of 106 (81% diabetic patients. Severe capillaroscopic changes were seen in 32 out of 54 (59% patients with microangiopathy, but in only seven out of 52 (13% patients without microangiopathy. Higher serum levels of sE-selectin (p < 0.001 and IL-18 (p < 0.05 were demonstrated in diabetic patients compared to controls. Significant differences of sE-selectin (p < 0.001 and IL-18 (p < 0.01 serum concentrations were observed between diabetic patients with microangiopathy and controls. Moreover, comparison between patients with and without microangiopathic complications showed a significantly higher capillaroscopic score and sE-selectin serum concentration in the group with microangiopathy (p < 0.001. Furthermore, diabetic patients with severe microvascular changes in capillaroscopy showed significantly higher IL-18 (p < 0.001 and sE-selectin (p < 0.05 serum levels than subgroups without changes or with mild abnormalities. Our findings suggest that abnormalities in nailfold capillaroscopy may reflect the extent of microvascular involvement and are associated with higher sE-selectin and IL-18 serum levels, as well as with microangiopathic complications in diabetic patients.

    Procalcitonin (PCT) levels are elevated early after birth in newborn infants; however, the physiological features and reference of serum PCT concentrations have not been fully studied in preterm infants. The aims of the current study were to establish an age-specific percentile-based reference curve of serum PCT concentrations in preterm infants and determine the features. The PCT concentration peaked in infants at 1 day old and decreased thereafter. At 1 day old, serum PCT concentrations in preterm infants <34 weeks' gestational age were higher than those in late preterm infants between 34 and 36 weeks' gestational age or term infants ≥37 weeks' gestational age. Although the 50-percentile value in late preterm and term infants reached the adult normal level (0.1 ng/mL) at 5 days old, it did not in preterm infants. It took 9 weeks for preterm infants to reach it. Serum PCT concentrations at onset in late-onset infected preterm infants were over the 95-percentile value. We showed that the physiological feature in preterm infants was significantly different from that in late preterm infants, even in those <37 weeks' gestational age. To detect late-onset bacterial infection and sepsis, an age-specific percentile-based reference curve may be useful in preterm infants. PMID:27033746

    In oncologic patients fever is a non-specific clinical marker of different clinical settings. Procalcitonin (PCT) seems to be the most promising infection marker. We aimed to define the potential role of PCT as an earlier diagnostic marker in patients with fever and solid tumor. This retrospective study enrolled 431 patients. All of them performed hemoculture (HE) and basal PCT assessment (reference laboratory cut-off: ≤0.5 or >0.5 ng/dL) before starting antibiotic therapy. Gram positive (G+), negative (G-) or Fungi infection were detected. A statistically significant difference in PCT levels between patients with positive and negative HE was observed (P PCT values in patients with positive and negative HE, we obtain in the positive HE subpopulation an AUC of 0.7 and a cut-off of 1.52 ng/dL reached high sensitivity (61.6%) and specificity (70.1%). Using this last cut-off, instead of the normal reference value, we achieve a risk reduction to overestimate an infection status of 23.4%. We support the clinic usefulness of serum PCT dosage in febrile advanced solid tumor patients. A PCT cut-off of 1.52 ng/dL could be helpful in the management of the antibiotic therapy preventing delays of oncologic treatments. PMID:27312877

    This meta-analysis was performed to determine the accuracy of procalcitonin (PCT) in predicting mortality in pneumonia patients with different pathogenic features and disease severities. A systematic search of English-language articles was performed using PubMed, Embase, Web of Knowledge and the Cochrane Library to identify studies. The diagnostic value of PCT in predicting prognosis was determined using a bivariate meta-analysis model. The Q-test and I(2) index were used to test heterogeneity. A total of 21 studies comprising 6007 patients were included. An elevated PCT level was a risk factor for death from community-acquired pneumonia (CAP) (risk ratio (RR) 4.38, 95% confidence interval (CI) 2.98-6.43), particularly in patients with a low CURB-65 score. The commonly used cut-off, 0.5 ng/mL, had low sensitivity (SEN) and was not able to identify patients at high risk of dying. Furthermore, the PCT assay with functional SEN pneumonia (VAP) and patients with CAP.

    In this study we investigate the diagnostic value of pleural fluid procalcitonin (PCT) in distinguishing infectious and noninfectious etiologies of pleural effusion. We reviewed the medical records of 75 hospitalized patients who underwent thoracentesis between 2011 and 2012. Data on pleural fluid lactate dehydrogenase (LDH), protein, albumin, cell count and differential, pH, Gram stain and culture, cytology, triglyceride, cholesterol, amylase, and PCT were collected. Data on serum LDH, protein, albumin, prothrombin time, normalized, and blood culture were also collected. Pleural effusions were classified into 2 groups, infectious and noninfectious. There were 18 infectious pleural effusions (IPE) and 57 noninfectious pleural effusions (NIPE). Median pleural fluid PCT was 1.088 ng/mL (0.312-2.940 ng/mL) in IPE and 0.123 ng/mL (0.05-0.263 ng/mL) in NIPE, with a P value 0.25 ng/mL had a sensitivity of 77.78% and specificity of 74.14% for diagnosing an IPE. A subgroup analysis of PCT in exudative infectious effusions versus exudative noninfectious malignant/paramalignant effusions showed higher levels in the former. PCT is a novel biomarker for diagnosing infectious pleural effusion, and it would be worthwhile to investigate the role of pleural PCT in assessing severity of illness, risk stratification, and antibiotic stewardship in hospitalized patients with pleural effusions.

    Full Text Available Background. Elevated cytokines levels correlate with sepsis severity and mortality but their role in the diagnosis is controversial, whereas Procalcitonin (PCT has been largely used. Recently, the mid-regional proadrenomedullin (MR-proADM has been combined with PCT for diagnosis optimization. In this study the combined measurement of PCT, MR-proADM, and cytokines in patients with sepsis was evaluated. Methods. One hundred and four septic patients and 101 controls were enrolled. Receiver operating characteristic (ROC analysis and multiple logistic regression were used to evaluate applicant markers for sepsis diagnosis. Markers with best Odds Ratio (OR were combined, and the posttest probability and a composite score were computed. Results. Based upon ROC curves analysis, PCT, MR-proADM, IL-6, IL-10, TNF-α, and MCP-1 were considered applicant for sepsis diagnosis. Among these PCT, MR-proADM , IL-6, and TNF-α showed the best OR. A better posttest probability was found with the combination of PCT with MR-proADM and PCT with IL-6 or TNF-α compared to the single marker. A composite score of PCT, MR-proADM, and TNF-α showed the best ROC curve in the early diagnosis of sepsis. Conclusion. The combination of PCT with other markers should expedite diagnosis and treatment of sepsis optimizing clinical management.

    Full Text Available Background. The sensitivity and the specificity of different methods to detect periprosthetic infection have been questioned. The current study aimed to investigate the kinetics of C-reactive protein (CRP and procalcitonin (PCT in patients undergoing uncomplicated elective total hip arthroplasty (THA, to provide a better interpretation of their levels in noninfectious inflammatory reaction. Methods. A total of 51 patients were included. Serum CRP and PCT concentrations were obtained before surgery, on the 1st, 3rd, and 7th postoperative days and after discharge on the 14th and 30th days and at 2 years. Results. Both markers were confirmed to increase after surgery. The serum CRP showed a marked increase on the 3rd postoperative day while the peak of serum PCT was earlier, even if much lower, on the first day. Then, they declined slowly approaching the baseline values by the second postoperative week. PCT mean values never exceed concentrations typically related to bacterial infections. Conclusions. CRP is very sensitive to inflammation. It could be the routine screening test in the follow-up of THA orthopaedic patients, but it should be complemented by PCT when there is the clinical suspicion of periprosthetic infection.

    Full Text Available Patients with chronic hepatitic C (HCV infection and normal serum alanine transaminase (ALT levels were considered to have mild disease. In Taiwan, these patients were not suggested for interferon (IFN based therapies. The aim of study is to compare therapeutic outcomes between HCV patients with normal and elevated ALT levels.We conducted a retrospective study on 3241 HCV patients treated by IFN based therapies. Patients with normal ALT levels were classified as group A (n = 186 while those with elevated ALT levels were group B (n = 3055.At baseline, incidence of diabetes mellitus, low platelet counts and cirrhosis were significantly higher in group B patients. The sustained virologic response (SVR rate was comparable between the 2 groups (65.3% vs. 65.3%, P = .993. But significantly higher incidence of HCC development after HCV treatment was observed in group B (7.4% vs. 3.2%, P = .032. No significant differences with respect to the outcome of liver decompensation, spontaneous bacterial peritonitis, and mortality were noted between 2 groups. Multivariate analysis showed younger age, female gender, non-HCV genotype 1, lower viral load, higher platelet counts and non-cirrhosis were favorable factors for achieving SVR, rather than ALT levels. Further analysis revealed older age, cirrhosis, lower platelet levels and non- peg-interferon treatment are risk factors of HCC development.HCV patients with normal ALT levels had similar response to antiviral therapy and low rate of HCC development after therapy. Antiviral therapies begun at early course of HCV infection may be beneficial to prevent disease progression.

    Introduction The aim of this study was to compare the early postoperative kinetics of procalcitonin (PCT) and C-reactive protein (CRP) serum levels in patients undergoing orthotopic liver transplantation (OLTx) with different immunosuppressive regimens. Methods PCT and CRP serum concentrations were measured in a group of 28 OLTx recipients before induction of anesthesia, at 4 and 8 hours following graft reperfusion, and daily until postoperative day 4. The same parameters were determined in 12 patients undergoing liver resection without conjunctive immunosuppressive therapy. Summary data are expressed as medians and ranges. Two-tailed nonparametric tests were performed and considered significant at p values of less than 0.05. Results The highest serum levels of PCT (median 3.0 ng/mL, minimum 1.4 ng/mL, maximum 13.9 ng/mL) were found in patients after OLTx without ATG therapy, on postoperative day 1. In patients with ATG administration, PCT levels were highly increased on postoperative day 1 (median 53.0 ng/mL, minimum 7.9 ng/mL, maximum 249.1 ng/mL). Thereafter, PCT values continuously decreased independently of further ATG administration in both groups of patients. No evidence of infection was present in either group. In 12 patients undergoing liver resection, peak serum PCT levels did not exceed 3.6 ng/mL. CRP serum levels in a group of patients with and without ATG therapy increased significantly on postoperative day 1, followed by a decrease. The highest levels of CRP were found in patients after liver resection on postoperative day 2 and decreased thereafter. Conclusion ATG administration to patients with OLTx is associated with an increase in serum PCT levels, with peak values on postoperative day 1, and this was in the absence of any evidence of infection. The results of this study indicate that ATG immunosuppressive therapy is a stimulus for the synthesis of PCT. PMID:18088403

    An association has been described between inflammation and the progression of hypertension (HT) and is shown with several biochemical parameters. Our aim was to examine the distribution of the serum procalcitonin (PCT), pentraxin (PTX)-3 and interleukin (IL)-33 levels and their relationship with carotid intima-media thickness (CIMT) in subjects with white coat HT (WCH), HT and normotension (NT) groups. Thirty-three patients with HT, 33 patients with WCH and 33 healthy subjects were enrolled in this study. PCT, PTX-3 and C-reactive protein (CRP) levels significantly increased in the HT group compared with the NT group. In addition, PCT and CRP levels were significantly higher in the WCH group than in the NT group. CIMT measurements were significantly higher in the WCH and HT groups than in the NT group. In the HT and WCH groups, there were significant positive correlations between PTX-3, PCT and CRP. In the WCH group, PTX-3 and PCT levels were significantly positively correlated with CIMT. PCT had area under the curve value of 0.817 which demonstrates its sufficiency to distinguish WCH from NT individuals. Our results suggest that in subjects with WCH and HT, which are characterized by increased cardiovascular risk, PTX-3 and PCT levels in the HT group and PCT levels in the WCH group are significantly and consistently higher than normotensives. Systemic inflammation moderately occurs in the WCH and HT groups. PCT monitoring may be a useful biomarker in inflammation related to atherosclerosis and early stage HT. PMID:26040439

  13. Thymidine kinase 2 deficiency-induced mitochondrial DNA depletion causes abnormal development of adipose tissues and adipokine levels in mice.

    Directory of Open Access Journals (Sweden)

    Joan Villarroya

    Full Text Available Mammal adipose tissues require mitochondrial activity for proper development and differentiation. The components of the mitochondrial respiratory chain/oxidative phosphorylation system (OXPHOS are encoded by both mitochondrial and nuclear genomes. The maintenance of mitochondrial DNA (mtDNA is a key element for a functional mitochondrial oxidative activity in mammalian cells. To ascertain the role of mtDNA levels in adipose tissue, we have analyzed the alterations in white (WAT and brown (BAT adipose tissues in thymidine kinase 2 (Tk2 H126N knockin mice, a model of TK2 deficiency-induced mtDNA depletion. We observed respectively severe and moderate mtDNA depletion in TK2-deficient BAT and WAT, showing both tissues moderate hypotrophy and reduced fat accumulation. Electron microscopy revealed altered mitochondrial morphology in brown but not in white adipocytes from TK2-deficient mice. Although significant reduction in mtDNA-encoded transcripts was observed both in WAT and BAT, protein levels from distinct OXPHOS complexes were significantly reduced only in TK2-deficient BAT. Accordingly, the activity of cytochrome c oxidase was significantly lowered only in BAT from TK2-deficient mice. The analysis of transcripts encoding up to fourteen components of specific adipose tissue functions revealed that, in both TK2-deficient WAT and BAT, there was a consistent reduction of thermogenesis related gene expression and a severe reduction in leptin mRNA. Reduced levels of resistin mRNA were found in BAT from TK2-deficient mice. Analysis of serum indicated a dramatic reduction in circulating levels of leptin and resistin. In summary, our present study establishes that mtDNA depletion leads to a moderate impairment in mitochondrial respiratory function, especially in BAT, causes substantial alterations in WAT and BAT development, and has a profound impact in the endocrine properties of adipose tissues.

  14. Level of cytogenetic damage and morphological abnormalities in peripheral blood erythrocytes of fish from the Techa river

    International Nuclear Information System (INIS)

    Low-level radioactive waste had been releasing to the Techa River from 1949 to 1956. Now it is a suitable water system to study the potential effect of chronic low level exposure of radiation. During that period over 76 million m3 of waste water was released into the river with total activity of 1.1 *1017 Bq. In 2012 we examined the erythrocytes in peripheral blood of fish (roach, perch, pike), inhabiting different part of the Techa River (Russia, Chelyabinsk region). Sampling was conducted twice a year (in May during spawning, and in August during feeding) at three stations with various levels of radioactive contamination: Station RT1 in the upper reach of the Techa River, station RT2 in the middle reach and station RT3 in the lower reach of the river. Determination of radionuclide concentrations in water, bottom sediments and fish was performed. An average above-background content of 90Sr in the body of fish inhabiting the Techa River is given in the table. Fish from the nearby Miass River was used as a control group. Blood was taken from the tail vein of live fish for the preparation of smears for determination of cytogenetic damage levels. 3,000 erythrocytes were analyzed for each fish on microscope Axioskop 50 (Carl Zeiss). Regression analyses found out significant dependency of the frequency of erythrocytes with micronuclei in blood on the burden of 90Sr in the body of roach in the summer period (F1,32=4.6; p=0.04). The given data do not allow excluding the genotoxic influence of radiation on fish. Another important effect is an increase in the frequency of erythrocytes with cell division pathology: with an increase of the burden of 90Sr in the body, an increase in the frequency of amitoses and the sum of division pathologies are noted in the body. Regression analyses indicated a significant dependency of these parameters on the burden of 90Sr in the body of fish (for the frequency of amitoses F1,199=6.3, p=0.01; for the frequency of pathology division

    Low-level radioactive waste had been releasing to the Techa River from 1949 to 1956. Now it is a suitable water system to study the potential effect of chronic low level exposure of radiation. During that period over 76 million m{sup 3} of waste water was released into the river with total activity of 1.1 *10{sup 17} Bq. In 2012 we examined the erythrocytes in peripheral blood of fish (roach, perch, pike), inhabiting different part of the Techa River (Russia, Chelyabinsk region). Sampling was conducted twice a year (in May during spawning, and in August during feeding) at three stations with various levels of radioactive contamination: Station RT1 in the upper reach of the Techa River, station RT2 in the middle reach and station RT3 in the lower reach of the river. Determination of radionuclide concentrations in water, bottom sediments and fish was performed. An average above-background content of {sup 90}Sr in the body of fish inhabiting the Techa River is given in the table. Fish from the nearby Miass River was used as a control group. Blood was taken from the tail vein of live fish for the preparation of smears for determination of cytogenetic damage levels. 3,000 erythrocytes were analyzed for each fish on microscope Axioskop 50 (Carl Zeiss).

The objective of this study was to investigate whether levels of procalcitonin (PCT, C-reactive protein (CRP, and neopterin in COPD patients could be useful in identifying the etiological origin of the exacerbation and assessing its prognosis.Methods: We included 318 consecutive COPD patients: 46 in a stable phase, 217 undergoing an exacerbation, and 55 with pneumonia. A serum sample was collected from each patient at the time of being included in the study. A second sample was also collected 1 month later from 23 patients in the exacerbation group. We compared the characteristics, biomarker levels, microbiological findings, and prognosis in each patient group. PCT and CRP were measured using an immunofluorescence assay. Neopterin levels were measured using a competitive immunoassay.Results: PCT and CRP showed significant differences among the three patient groups, being higher in patients with pneumonia, followed by patients with exacerbation (P < 0.0001. For the 23 patients with paired samples, PCT and CRP levels decreased 1 month after the exacerbation episode, while neopterin increased. Neopterin showed significantly lower levels in exacerbations with isolation of pathogenic bacteria, but no differences were found for PCT and CRP. No significant differences were found when comparing biomarker levels

    Procalcitonin (PCT) is an early and highly specific biomarker in response to bacterial infection. The PCT-guided antibiotic therapy has demonstrated to be more efficient than standard therapy to reduce in antibiotic use without adverse outcome in mortality. The PCT detection in clinics is required to be highly sensitive with a sensitivity of 0.5 ng/ml. At present, the technologies for PCT detection are limited. This paper reported a highly sensitive nanoimprinted gold nanopillar array chip for PCT detection. To achieve high sensitivity for PCT detection, the gold nanopillar array sensing chip was designed by plasmonic simulation and fabricated by high fidelity nanoimprinting technology. The gold nanopillars of 140 nm were nanoimprinted on glass substrate. A robust sandwich bioassay of capture antibody /PCT / quantum dot (QD) conjugated detection antibody was established on the gold nanopillar array chip to detect PCT. The nanopillars serve as localized surface plasmon resonance (LSPR) generators to enhance the fluorescent emission from QD. A limit of detection (LOD) of 0.5 ng/ml was achieved for PCT detection. This is the first time that PCT is detected with such high sensitivity by LSPR enhanced QD emission. By considering the low-cost, high sensitivity of the bioassay, as well as the inexpensive mass fabrication of the high quality chips, this novel nanoimprinted gold nanopillar array chip is particularly useful for developing a point-of-care system for PCT detection.

    A surface plasmon resonance (SPR) biosensor has been developed for rapid immunoassay of procalcitonin (PCT) with high detection sensitivity and reproducibility. The 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloride (EDC)-activated protein A (PrA), diluted in 1% (v/v) 3-aminopropyltriethoxysilane (APTES) was dispensed on a KOH-treated Au-coated SPR chip, resulting in the covalent binding of PrA in 30 min. This "single-step" PrA immobilization strategy led to the oriented binding of the anti-PCT antibody (Ab) on a PrA-functionalized gold (Au) chip. The leach-proof immobilization procedure is five-fold faster than conventional counterparts, enabling high detection specificity and reproducibility. The IA detects 4-324 ng mL(-1) of PCT with a limit of detection (LOD) and a limit of quantification (LOQ) of 4.2 ng mL(-1) and 9.2 ng mL(-1), respectively. It was capable of detecting PCT in real sample matrices and patient samples with high precision. The Ab-bound SPR chips were stable for more than five weeks. PMID:27619095

    Full Text Available Sepsis appears to be due to an uncontrolled pro and anti-inflammatory response leading to organ dysfunction until shock and death.Accuracy of diagnosis and appropriate treatment affect the outcome. Aim of the study was to investigate if the levels of Osteopontin (OPN and Soluble Urokinase-type Plasminoge Activator Receptor (suPAR might be early markers of sepsis and if these markers play a role in predicting the progression to septic shock. Methods:The levels of OPN, suPAR, C-reactive protein (CRP and procalcitonin (PCT were measured in patients at higher risk of infection. The samples were collected from the day of admission for the following fifteenth day. During recovery Sistemic Inflammatory Response Syndrome (SIRS criteria, blood chemistry data, blood gas- analysis, lactate and diuresis were collected. Microbiological culture were performed according to the clinical condition. Results: 29 patients were enrolled in the study, including 14 subjects with positive blood cultures.The values of OPN, PCT, suPAR and CRP were significantly increased in patients with positive blood cultures than those with negative blood cultures.Analysing changes of the levels of OPN, suPAR, PCT and CRP in patients with septic shock, the values of OPN increased in advance to the clinical diagnosis of septic shock, while the values of suPAR and PCT slight delay compared to those OPN.The levels of CRP were independent from the onset of septic shock state. Conclusions: These preliminary data suggest that Osteopontin and suPAR can be used as early markers of sepsis and might be useful in monitoring of septic outcome to predict a possible evolution to septic shock.

    In cultured cells from normal individuals and from patients having ataxia telangiectasia (AT) the rate of unscheduled DNA synthesis (UDS) induced by UV light was investigated by autoradiography. The number of grains in 6 different AT cell strains was similar to that observed in normal cells. Exposure of normal cells to doses of X-rays up to 20 krad had no influence on the rate of UV-induced UDS. In contrast, the UV-induced UDS was significantly modified in AT cells by treatment with X-rays. In AT cell strains that were reported to have reduced levels of ..gamma..-ray-induced repair DNA synthesis ('excision-deficient' AT cells) the effect of X-rays on UV-induced UDS was inhibitory, whereas UV-induced UDS was stimulated by X-ray exposure in 'excision-proficient' AT cell strains. Different UV and X-ray dose-response relationships were seen in the two categories of AT cell strains.

    Full Text Available Procalcitonin (PCT and Interleukin-6 (IL-6 have emerged as biomarkers for different inflammatory conditions. The purpose of the study was to evaluate the role of PCT and IL-6 as biomarkers of cancer and its progression in a large cohort of patients. This cross-sectional study included residual plasma samples collected from cancer patients, and control subjects without cancer. Levels of PCT and IL-6 were determined by Kryptor compact bioanalyzer. We identified 575 febrile cancer patients, 410 non-febrile cancer patients, and 79 non-cancer individuals. The median PCT level was lower in control subjects (0.029 ng/ml compared to cancer patients with stage I-III disease (0.127 ng/ml (p<0.0001 and stage IV disease (0.190 ng/ml (p<0.0001. It was also higher in febrile cancer patients (0.310 ng/ml compared to non-febrile cancer patients (0.1 ng/ml (p<0.0001. Median IL-6 level was significantly lower in the control group (0 pg/ml than in non-febrile cancer patients with stages I-III (7.376 pg/ml or stage IV (9.635 pg/ml (p<0.0001. Our results suggest a potential role for PCT and IL-6 in predicting cancer in non-febrile patients. In addition, PCT is useful in detecting progression of cancer and predicting bacteremia or sepsis in febrile cancer patients.

    Full Text Available BACKGROUND: The early diagnosis of acute abdomen is of great importance. To date, several inflammatory markers have been used for the diagnosis of acute abdominal conditions, including acute appendicitis. The aim of this study was to evaluate the diagnostic utility of D-dimer, Procalcitonin (PCT and C-reactive protein (CRP measurements in the acute appendicitis.METHODS: This prospective study was conducted between March 1st, 2010 and July 1st, 2011. In this period, seventy-eight patients were operated with the diagnosis of acute appendicitis, and D-dimer, PCT and CRP levels of the patients were measured. The patients were grouped as phlegmonous appendicitis (Group 1, gangrenous appendicitis (Group 2, perforated appendicitis (Group 3 and negative appendectomy (Group 4 according to the surgical findings and histopathological results.RESULTS: Of 78 patients, 54 (69.2 % were male and 24 (30.8 % were female, and the mean age was 25.4 ± 11.1 years (range, 18 to 69 years. 66 (84.6 % patients had increased leukocyte count (white blood cell count. The PCT values were higher than the upper normal limit in 20 (25.6% patients, followed by D-dimer in 22 (28.2 % patients and CRP in 54 (69.2 % patients. The diagnostic value of leukocyte count and CRP in acute appendicitis was higher than that of the other markers, whereas leukocyte count showed very low specificity. CRP values were higher in perforated appendicitis when compared with the phlegmonous appendicitis (p<0.05. However, PCT and D-dimer showed lower diagnostic values (26% and 31%, respectively.CONCLUSION: An increase in CRP levels alone is not sufficient to make the diagnosis of acute appendicitis. However, CRP levels may differentiate between phlegmonous appendicitis and perforated appendicitis. Due to their low sensitivity and diagnostic value, PCT and D-dimer are not better markers than CRP for the diagnosis of acute appendicitis.

    The hepatic ischemia-reperfusion syndrome was investigated in 28 patients undergoing elective partial liver resection with intraoperative occlusion of hepatic inflow (Pringle maneuver) using the technique of liver vein catheterization. Hepatic venous oxygen saturation (ShvO2) was monitored continuously up to 24 hours after surgery. Aspartate aminotransferase, glutamate dehydrogenase, gamma-glutamyl transpeptidase, pseudocholinesterase, alpha-glutathione S-transferase, reduced and oxidized glutathione, procalcitonine, and interleukin-6 were serially measured both before and after Pringle maneuver during the resection and postoperatively in arterial and/or hepatic venous blood. ShvO2 measurement demonstrated that peri- and postoperative management was suitable to maintain an optimal hepatic oxygen supply. As expected, we were able to demonstrate a typical enzyme pattern of postischemic liver injury. There was a distinct decrease of reduced glutathione levels both in arterial and hepatic venous plasma after LR accompanied by a strong increase in oxidized glutathione concentration during the phase of reperfusion. We observed increases in procalcitonin and interleukin-6 levels both in arterial and hepatic venous blood after declamping. Our data support the view that liver resection in man under conditions of inflow occlusion resulted in ischemic lesion of the liver (loss of glutathione synthesizing capacity with disturbance of protection against oxidative stress) and an additional impairment during reperfusion (liberation of reactive oxygen species, local and systemic inflammation reaction with cytokine production). Additionally, we found some evidence for the assumption that the liver has an export function for reduced glutathione into plasma in man. PMID:12877355

    Full Text Available Abstract Background Recognizing infection is crucial in immunocompromised patients with organ dysfunction. Our objective was to assess the diagnostic accuracy of procalcitonin (PCT in critically ill immunocompromised patients. Methods This prospective, observational study included patients with suspected sepsis. Patients were classified into one of three diagnostic groups: no infection, bacterial sepsis, and nonbacterial sepsis. Results We included 119 patients with a median age of 54 years (interquartile range [IQR], 42-68 years. The general severity (SAPSII and organ dysfunction (LOD scores on day 1 were 45 (35-62.7 and 4 (2-6, respectively, and overall hospital mortality was 32.8%. Causes of immunodepression were hematological disorders (64 patients, 53.8%, HIV infection (31 patients, 26%, and solid cancers (26 patients, 21.8%. Bacterial sepsis was diagnosed in 58 patients and nonbacterial infections in nine patients (7.6%; 52 patients (43.7% had no infection. PCT concentrations on the first ICU day were higher in the group with bacterial sepsis (4.42 [1.60-22.14] vs. 0.26 [0.09-1.26] ng/ml in patients without bacterial infection, P 0.5 ng/ml had 100% sensitivity but only 63% specificity for diagnosing bacterial sepsis. The area under the receiver operating characteristic (ROC curve was 0.851 (0.78-0.92. In multivariate analyses, PCT concentrations > 0.5 ng/ml on day 1 independently predicted bacterial sepsis (odds ratio, 8.6; 95% confidence interval, 2.53-29.3; P = 0.0006. PCT concentrations were not significantly correlated with hospital mortality. Conclusion Despite limited specificity in critically ill immunocompromised patients, PCT concentrations may help to rule out bacterial infection.

  14. Useulness of B Natriuretic Peptides and Procalcitonin in Emergency Medicine

    2008-01-01

    Full Text Available Congestive heart failure (CHF is the main cause of acute dyspnea in patients presented to an emergency department (ED, and it is associated with high morbidity and mortality. B-type natriuretic peptide (BNP is a polypeptide, released by ventricular myocytes directly proportional to wall tension, for lowering renin-angiotensin-aldosterone activation. For diagnosing CHF, both BNP and the biologically inactive NT-proBNP have similar accuracy. Threshold values are higher in elderly population, and in patients with renal dysfunction. They might have also a prognostic value. Studies demonstrated that the use of BNP or NT-proBNP in dyspneic patients early in the ED reduced the time to discharge, total treatment cost. BNP and NT-proBNP should be available in every ED 24 hours a day, because literature strongly suggests the beneficial impact of an early appropriate diagnosis and treatment in dyspneic patients. Etiologic diagnosis of febrile patients who present to an ED is complex and sometimes difficult. However, new evidence showed that there are interventions (including early appropriate antibiotics, which could reduce mortality rate in patients with sepsis. For diagnosing sepsis, procalcitonin (PCT is more accurate than C-reactive protein. Thus, because of its excellent specificity and positive predictive value, an elevated PCT concentration (higher than 0.5 ng/mL indicates ongoing and potentially severe systemic infection, which needs early antibiotics (e.g. meningitis. In lower respiratory tract infections, CAP or COPD exacerbation, PCT guidance reduced total antibiotic exposure and/or antibiotic treatment duration.

    Purpose The amniotic fluid volume (AFV) is known as a predictor for the wellness of a fetus. We aimed to investigate whether N-terminal pro-brain natriuretic peptide (NTproBNP) levels reflect AFV abnormalities in otherwise normal fetuses. Methods We recruited 24 women with isolated oligohydramnios, 23 women with isolated polyhydramnios, and 36 women with normal AFV at a tertiary referral center. NT-proBNP levels in umbilical venous samples and the individual characteristics of the three groups were compared. One-way ANOVA and Kruskal-Wallis analysis of variance were used for multi-group comparisons of continuous variables. When a significant difference was detected, the Scheffe test was performed as a post-hoc analysis. Proportions were compared using the Chi-square (χ2) test. Results Maternal age, body mass indices, weight gained in pregnancy and NT-proBNP levels were similar among the three groups. Apgar scores at 1 and 5 minutes significantly correlated with NT-proBNP levels in all newborns (Spearman's r = 0.23; p = 0.03 and Spearman's r = 0.24; p = 0.02, respectively). The umbilical venous NT-proBNP levels did not differ between newborns who needed mechanical ventilation and those who didn't (p = 0.595). Conclusions NT-proBNP is a biomolecule that may provide insights into the pathogenesis of fetal circulatory problems and subsequent renal failure. Further investigations are warranted. PMID:27096950

  1. Procalcitonin: A New Biomarker for Medullary Thyroid Cancer? A Systematic Review.

    2016-08-01

    Medullary thyroid cancer (MTC) is a rare but aggressive thyroid malignancy. The gold-standard biomarker for its diagnosis and follow-up is calcitonin (CT); however, it has a variable half-life dependent on its circadian variability. It has been suggested that a more stable hormone, procalcitonin (PCT), may overcome these problems and its introduction to routine practice may give more accurate results in the diagnosis and follow-up of MTC. We systematically reviewed Pubmed, Scopus, Biosis Previews and Embase databases up to March 2016. A total of 15 out of 184 articles were retrieved and analyzed. Of these 15 studies, 3 were case reports. In these 15 studies, the values of CT and PCT were assessed in both patients with MTC and patients that were either healthy volunteers or with benign/malignant thyroid nodular disease or with bacterial infection. Our search suggests that PCT seems to be a useful biomarker for the diagnosis and follow-up of MTC when used in conjunction with CT, particularly in a small proportion of tumors that are CT-negative or secrete low levels of CT. So far, there has not been enough data to suggest a specific threshold for normal PCT. However, most studies indicate a value of 0.1 ng/ml as an acceptable cut-off in everyday clinical practice. At present, CT should continue to be the primary biomarker in MTC with the addition of PCT in some patient groups. Nevertheless, larger patient series need to be conducted in order to provide safer and more accurate results. PMID:27466480

    Full Text Available Bacterial infection is an important trigger of vaso-occlusive crisis (VOC in sickle cell anaemia (SCA. SCA Patients with VOC have signs of inflammation and it is difficult to diagnose bacterial infection in them. This study was undertaken to evaluate serum procalcitonin (PCT as a biomarker of bacterial infection in acute sickle cell vaso-occlusive crisis. Hundred SCA patients were studied at Sickle Cell Clinic and Molecular Biology Laboratory, V.S.S. Medical College, Burla, Odisha, India. SCA was diagnosed by haemoglobin electrophoresis, HPLC and molecular analysis. Patients were divided into 3categories namely Category-A (VOC/ACS with fever but without evidence of bacterial infection-66 patients; Category-B (VOC with fever and documentedbacterial infection-24 patients; and Category-C (Patients in steady statewithout VOC/ACS or fever-10 patients. Investigations like complete blood count, C-reactive protein estimation and PCT measurement was done in all the cases. There was no significant difference in total leucocytes count and C-reactiveprotein values between category A and B. In category A the PCT level was 0.5ng/mL with 87.5% of cases having >2ng/mL. In category C, PCT value was 2ng/mL is indicative of bacterial infection necessitating antimicrobial therapy. Patients with indeterminate PCT value of0.5-2ng/mL, need a repeat PCT estimation or an empirical antibiotic therapyawaiting the availability of microbiological report as deemed necessary.

    Full Text Available BACKGROUND: Pneumonia remains the leading cause of death in young children. The poor specificity of chest radiographs (CXRs to diagnose pneumococcal pneumonia may underestimate the efficacy of pneumococcal conjugate vaccine in preventing pneumococcal pneumonia. METHODS AND FINDINGS: The efficacy of nine-valent pneumococcal conjugate vaccine among children not infected with HIV (21%; 95% confidence interval, 1%-37% increased when CXR-confirmed pneumonia was associated with serum C-reactive protein of 120 mg/l (12 mg/dl or more and procalcitonin of 5.0 ng/ml or more (64%; 95% confidence interval, 23%-83%. Similar results were observed in children infected with HIV. CONCLUSION: C-reactive protein and procalcitonin improve the specificity of CXR to diagnose pneumococcal pneumonia and may be useful for the future evaluation of the effectiveness of pneumococcal conjugate vaccine in preventing pneumococcal pneumonia.

    Objective To study the effect of non-infectious factors on serum procalcitonin(PCT) in preterm neonates.MethodThe premature infants of neonatal intensive care unit(NICU) in our hospital were chosen from gestational age ranged from 33 to 36 weeks, birth time less than 12 hours without premature rupture and hospitalization period from January 2012 to December 2012. All of the premature infants were drawn blood immediately admitted to hospital and C-reactive protein (CRP), blood cultures and procalcitonin were tested. The types of premature infants non-infectious diseases included intracranial hemorrhage (ICH), neonatal respiratory distress syndrome (NRDS), neonatal asphyxia and the control group (preterm infants) without disease. The blood routine , C-reactive protein, blood culture, procalcitonin and other infections indicators in each group were monitored dynamicly in order to study the impact of these non-infectious diseases on serum procalcitonin concentrations by statistical analysis.Results ① Compared with the current literature recommended serum procalcitonin concentrations (<0.5ng / ml), procalcitonin concentrations in preterm neonates singniifcantly increase (1.07± 0.76) ng / ml.②Compared with control group (1.07±0.76) ng/ml,the procalcitonin levels in intracranial hemorrhage group (2.12± 0.99) ng/ml, neonatal respiratory distress syndrome group (2.28±1.09) ng/ml and asphyxia group (3.64± 3.17) ng / ml signiifcantly increased (F= 10.462,P <0.05).There were no signiifcant differences (F= 0.173,P= 0.950) among the different levels of intracranial hemorrhage group; Compared with the ifrst grade NRDS , the procalcitonin leves in second grade and third grade NRDS groups were significantly increased (F=5.475,P= 0.010); The procalciton level in severe asphyxia group was signiifcantly higher than in mild asphyxia group (t= 5.245,P= 0.003).

    Full Text Available Procalcitonin (PCT has been widely investigated for its prognostic value in septic patients. However, studies have produced conflicting results. The purpose of the present meta-analysis is to explore the diagnostic accuracy of a single PCT concentration and PCT non-clearance in predicting all-cause sepsis mortality. We searched PubMed, Embase, Web of Knowledge and the Cochrane Library. Articles written in English were included. A 2 × 2 contingency table was constructed based on all-cause mortality and PCT level or PCT non-clearance in septic patients. Two authors independently evaluated study eligibility and extracted data. The diagnostic value of PCT in predicting prognosis was determined using a bivariate meta-analysis model. We used the Q-test and I2 index to test heterogeneity. Twenty-three studies with 3,994 patients were included. An elevated PCT level was associated with a higher risk of death. The pooled relative risk (RR was 2.60 (95% confidence interval (CI, 2.05-3.30 using a random-effects model (I(2 = 63.5%. The overall area under the summary receiver operator characteristic (SROC curve was 0.77 (95% CI, 0.73-0.80, with a sensitivity and specificity of 0.76 (95% CI, 0.67-0.82 and 0.64 (95% CI, 0.52-0.74, respectively. There was significant evidence of heterogeneity for the PCT testing time (P = 0.020. Initial PCT values were of limited prognostic value in patients with sepsis. PCT non-clearance was a prognostic factor of death in patients with sepsis. The pooled RR was 3.05 (95% CI, 2.35-3.95 using a fixed-effects model (I(2 = 37.9%. The overall area under the SROC curve was 0.79 (95% CI, 0.75-0.83, with a sensitivity and specificity of 0.72 (95% CI, 0.58-0.82 and 0.77 (95% CI, 0.55-0.90, respectively. Elevated PCT concentrations and PCT non-clearance are strongly associated with all-cause mortality in septic patients. Further studies are needed to define the optimal cut-off point and the optimal definition of PCT non-clearance for

    Full Text Available Abstract Background In the ICU, bacteremia is a life-threatening infection whose prognosis is highly dependent on early recognition and treatment with appropriate antibiotics. Procalcitonin levels have been shown to distinguish between bacteremia and noninfectious inflammatory states accurately and quickly in critically ill patients. However, we still do not know to what extent the magnitude of PCT elevation at the onset of bacteremia varies according to the Gram stain result. Methods Review of the medical records of every patient treated between May, 2004 and December, 2006 who had bacteremia caused by either Gram positive (GP or Gram negative (GN bacteria, and whose PCT dosage at the onset of infection was available. Results 97 episodes of either GN bacteremia (n = 52 or GP bacteremia (n = 45 were included. Procalcitonin levels were found to be markedly higher in patients with GN bacteremia than in those with GP bacteremia, whereas the SOFA score value in the two groups was similar. Moreover, in the study population, a high PCT value was found to be independently associated with GN bacteremia. A PCT level of 16.0 ng/mL yielded an 83.0% positive predictive value and a 74.0% negative predictive value for GN-related bacteremia in the study cohort (AUROCC = 0.79; 95% CI, 0.71–0.88. Conclusion In a critically ill patient with clinical sepsis, GN bacteremia could be associated with higher PCT values than those found in GP bacteremia, regardless of the severity of the disease.

    Full Text Available The empiric antibiotic therapy can result in antibiotic overuse, development of bacterial resistance and increasing costs in critically ill patients. The aim of the present study was to evaluate the effect of procalcitonin (PCT guide treatment on antibiotic use and clinical outcomes of patients admitted to intensive care unit (ICU with systemic inflammatory response syndrome (SIRS.  A total of 60 patients were enrolled in this study and randomly divided into two groups, cases that underwent antibiotic treatment based on serum level of PCT as PCT group (n=30 and patients who undergoing antibiotic empiric therapy as control group (n=30. Our primary endpoint was the use of antibiotic treatment. Additional endpoints were changed in clinical status and early mortality. Antibiotics use was lower in PCT group compared to control group (P=0.03. Current data showed that difference in SOFA score from the first day to the second day after admitting patients in ICU did not significantly differ (P=0.88. Patients in PCT group had a significantly shorter median ICU stay, four days versus six days (P=0.01. However, hospital stay was not statistically significant different between two groups, 20 days versus 22 days (P=0.23.  Early mortality was similar between two groups. PCT guidance administers antibiotics reduce antibiotics exposure and length of ICU stay, and we found no differences in clinical outcomes and early mortality rates between the two studied groups.

    As no specific laboratory test has been identified, PFAPA (periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis) remains a diagnosis of exclusion. We searched for a practical use of procalcitonin (PCT) and C-reactive protein (CRP) in distinguishing PFAPA attacks from acute bacterial and viral infections. Levels of PCT and CRP were measured in 38 patients with PFAPA and 81 children diagnosed with an acute bacterial (n=42) or viral (n=39) infection. Statistical analysis with the use of the C4.5 algorithm resulted in the following decision tree: viral infection if CRP≤19.1 mg/L; otherwise for cases with CRP>19.1 mg/L: bacterial infection if PCT>0.65ng/mL, PFAPA if PCT≤0.65 ng/mL. The model was tested using a 10-fold cross validation and in an independent test cohort (n=30), the rule’s overall accuracy was 76.4% and 90% respectively. Although limited by a small sample size, the obtained decision tree might present a potential diagnostic tool for distinguishing PFAPA flares from acute infections when interpreted cautiously and with reference to the clinical context.

    Full Text Available Background: Acute exacerbations of chronic obstructive pulmonary disease (AeCOPD are important causes of morbidity and mortality. In this study, we analyzed procalcitonin (PCT levels in AeCOPD and stable period of COPD in order to evaluate usage of PCT in the prediction of the severity of AeCOPD, and its value on the planing of noninvasive positive pressure ventilation (NPPV. Materials and Methods: In this cross sectional study (2009-2010 118 COPD patients were enrolled, 68 of them (58% were in acute exacerbations (case group. The others had stabile COPD and they were defined as control group. Results: In case group the mean levels of PCT (0.19 ± 0.02 C-Reactive Protein (44.7 ± 5.92, erythrocyte sedimentation rate (28.4 ± 2.65, white blood cell (9.4 ± 0.43 and %neutrophils (69.9 ± 1.22 were significantly higher than controls (P = 0.0001. There was no difference between PCT levels based on stages of COPD. There were significiant differences in mean PCT levels according to type and severity of AeCOPD. Mean PCT level in hospitalized patients receiving NPPV was 0.36 ng/ml, while it was 0.15 ng/ml for those treated without NPPV (P = 0.0001. PCT cut-off value for NPPV indication was determined to be 0.10 ng/ml. Conclusions: PCT levels were found to be higher in AeCOPD patients than in stable COPD patients, as expected. Also mean PCT levels increased especially in cases with severe AeCOPD and those receiving NPPV among them. In the present study, we determined a cut off value of PCT as 0.10 ng/ml as a predictor of necessity of NPPV in AeCOPD.

    Sandrine Leroy

    Full Text Available BACKGROUND: Predicting vesico-ureteral reflux (VUR ≥3 at the time of the first urinary tract infection (UTI would make it possible to restrict cystography to high-risk children. We previously derived the following clinical decision rule for that purpose: cystography should be performed in cases with ureteral dilation and a serum procalcitonin level ≥0.17 ng/mL, or without ureteral dilatation when the serum procalcitonin level ≥0.63 ng/mL. The rule yielded a 86% sensitivity with a 46% specificity. We aimed to test its reproducibility. STUDY DESIGN: A secondary analysis of prospective series of children with a first UTI. The rule was applied, and predictive ability was calculated. RESULTS: The study included 413 patients (157 boys, VUR ≥3 in 11% from eight centers in five countries. The rule offered a 46% specificity (95% CI, 41-52, not different from the one in the derivation study. However, the sensitivity significantly decreased to 64% (95%CI, 50-76, leading to a difference of 20% (95%CI, 17-36. In all, 16 (34% patients among the 47 with VUR ≥3 were misdiagnosed by the rule. This lack of reproducibility might result primarily from a difference between derivation and validation populations regarding inflammatory parameters (CRP, PCT; the validation set samples may have been collected earlier than for the derivation one. CONCLUSIONS: The rule built to predict VUR ≥3 had a stable specificity (ie. 46%, but a decreased sensitivity (ie. 64% because of the time variability of PCT measurement. Some refinement may be warranted.

    Cloud computing is facing severe safety challenges because of its open operation environment.Traditional instruction detection system (IDS)can no longer fully adapt to new computing network environment,such as cloud computing.In view of that the end-user’s credibility has significant impact on the credibility of virtual machine,we present a user abnormal level-based dynamic configuration strategy of defense levels for virtual machines by making use of the credibility mechanism of dynamic behaviour and the idea of social trust.First,the strategy uses sliding window-based behaviour assessment mechanism to assess user’s behaviour,then based on the assessment result it divides the virtual machine the user located into different safety level domains.At last,it realises the dynamic configuration of safety levels of virtual machine through domain division rules chain,which greatly improves the efficiency of IDS.Simulation experiment shows that the proposed multi-level defense mechanism has good reliability.%云计算环境下,开放的运行环境使其面临重大的安全挑战,传统的入侵检测系统已经不能完全适合云计算等新型计算网络环境。鉴于终端用户的可信性对虚拟机可信性的影响,利用动态的行为可信性机制和社会信任的思想,提出一种基于用户异常等级的虚拟机防御等级动态配置策略。首先,利用滑动窗口行为评估机制评估用户行为,然后根据评估结果将用户所在的虚拟机划分为不同安全等级域,最后,通过分域规则链机制实现虚拟机安全等级的动态配置,有效提高入侵检测系统的效率。模拟实验表明,提出的多等级的防御机制具有良好的可靠性。

    Procalcitonin (PCT) is a biological marker of infection. We present the cas of a patient who has presented a high concentration of PCT with PCT-Q test (Brahms). At the same time, the concentration of CRP is remained low, which is no physiological. Then, PCT concentration has been determinated with an automatic system (Kryptor-Brahms) and finded at low than 0.5 microg/l. Brahms company has searched an analytical interference: human anti-mouse antibodies (HAMA) were positive. If PCT concentration stay a marker of infection for the most part, this case show that biologists have to keep in mind that immunological assays remain submitted to interferences.

    Full Text Available BACKGROUND: Biochemical markers may be used in diagnosis, prognostic and monitoring treatment and therapy for sepsis patients. In this study we used Lipopolysacharide Binding Protein (LBP, serum-Intercellular Adhesion Molecule-1 (ICAM-1, Procalcitonin (PCT and protein C activity. LBP is related to lipopolysachharide or gram-negative bacterial endotoxin which bound to LBP and induced inflammatory response. ICAM-1 is associated with endothelial dysfunction in response to systemic inflammatory and septic condition. PCT increased in bacterial infection and in severe systemic inflammatory. Role of Protein C is protecting the intravascular system to systemic inflammation, sepsis and the concomitant intravascular coagulopathy. The aim of this study was to examine the associations between levels of serum LBP, sICAM-1, PCT, and protein C activity with the clinical outcome of SIRS or sepsis patients. METHODS: We included 19 post surgery patients with SIRS criteria from intensive care unit (ICU and evaluated the level of LBP serum with Chemiliuminescent Enzyme Immunoassay (Diagnostic Product Co., ICAM-1 with ELISA (R&D System, PCT with immunochromatography (BRAHMS, protein C activity with chromogenic method (Dade Behring. We performed the samples serially at the first admission of patients and after 72 hours. Data were analysed by non-parametric with Wilcoxon test and Mann-Whitney test. Correlation study between biomarkers calculated by Kendall’s tau and Spearman’s rho. RESULTS: Of 19 patients, 9 (47,4% died and 10 (52,6% surviving. The level of LBP serum decreased after 72 hours in surviving-sepsis patients, and increased in nonsurviving sepsis patients with significant different levels at 72 hours examination (p0.05. In all patients were found high level of PCT serum since the first admission examination, decreasing levels were occurred significantly in surviving patients after 72 hours (p0.05 both in surviving and non-surviving patients.

    Full Text Available Despite vaccines and improved medical intensive care, clinicians must continue to be vigilant of possible Meningococcal Disease in children. The objective was to establish if the procalcitonin test was a cost-effective adjunct for prodromal Meningococcal Disease in children presenting at emergency department with fever without source.Data to evaluate procalcitonin, C-reactive protein and white cell count tests as indicators of Meningococcal Disease were collected from six independent studies identified through a systematic literature search, applying PRISMA guidelines. The data included 881 children with fever without source in developed countries.The optimal cut-off value for the procalcitonin, C-reactive protein and white cell count tests, each as an indicator of Meningococcal Disease, was determined. Summary Receiver Operator Curve analysis determined the overall diagnostic performance of each test with 95% confidence intervals. A decision analytic model was designed to reflect realistic clinical pathways for a child presenting with fever without source by comparing two diagnostic strategies: standard testing using combined C-reactive protein and white cell count tests compared to standard testing plus procalcitonin test. The costs of each of the four diagnosis groups (true positive, false negative, true negative and false positive were assessed from a National Health Service payer perspective. The procalcitonin test was more accurate (sensitivity=0.89, 95%CI=0.76-0.96; specificity=0.74, 95%CI=0.4-0.92 for early Meningococcal Disease compared to standard testing alone (sensitivity=0.47, 95%CI=0.32-0.62; specificity=0.8, 95% CI=0.64-0.9. Decision analytic model outcomes indicated that the incremental cost effectiveness ratio for the base case was £-8,137.25 (US $ -13,371.94 per correctly treated patient.Procalcitonin plus standard recommended tests, improved the discriminatory ability for fatal Meningococcal Disease and was more cost

    A pumpless interventional arteriovenous lung assist device (iLA) facilitates the removal of carbon dioxide from the blood and is used as part of the lung-protective ventilation strategy in patients with acute respiratory distress syndrome (ARDS). In case of bacterial infection, delayed antimicrobial therapy increases the mortality in this group of high-risk critically ill patients, whereas overtreatment promotes bacterial resistance and leads to increased drug toxicity and costs. Besides clinical signs and symptoms, antimicrobial treatment is based on the kinetics of biomarkers such as procalcitonin (PCT). We hereby report an up to 10-fold increase in PCT serum concentrations in four mechanically ventilated patients with ARDS detected within 12-20 hours after iLA implantation in the absence of any infection. Procalcitonin concentrations returned to nearly baseline values in all patients on the fourth day after iLA implantation. We discuss the possible mechanisms of PCT induction in this specific patient population and recommend the onset of antibiotics administration after iLA implantation to be carefully considered in the context of other clinical findings and not solely based on the PCT kinetics. Repeated PCT measurements in short time intervals should be performed in these patients.

    Early diagnosis and prompt treatment of spontaneous bacterial peritonitis (SBP) due to end-stage liver disease is vital to shorten hospital stays and reduce mortality. Many studies have explored the potential usefulness of serum procalcitonin (PCT) in predicting SBP. The aim of this study is to evaluate the overall diagnostic accuracy of PCT levels for identifying SBP due to end-stage liver disease.After performing a systematic search of the Medline, Embase, and Cochrane databases for studies that evaluated the diagnostic role of PCT for SBP, sensitivity, specificity, and other measures of accuracy of PCT concentrations in serum for SBP diagnosis were pooled using random-effects models. A summary receiver operating characteristic curve was used to summarize overall test performance.Seven publications met the inclusion criteria covering 742 episodes of suspected SBP along with 339 confirmed cases. The summary estimates for serum PCT in the diagnosis of SBP attributable to end-stage liver disease were: sensitivity 0.82 (95% CI 0.79-0.87), specificity 0.86 (95% CI 0.82-0.89), positive likelihood ratio 4.94 (95% CI 2.28-10.70), negative likelihood ratio 0.22 (95% CI 0.10-0.52), and diagnostic OR 22.55 (95% CI 7.01-108.30). The area under the curve was 0.92. There was evidence of significant heterogeneity but no evidence of publication bias.Serum PCT is a relatively sensitive and specific test for the identification of SBP. However, due to the limited high-quality studies available, medical decisions should be carefully made in the context of both PCT test results and other clinical findings.

    Urinary liver-type fatty acid-binding protein (L-FABP) reflects the degree of stress in proximal tubules of the kidney. We examined the level of L-FABP in type-2 diabetes mellitus (T2DM) patients with chronic kidney disease (CKD) stage G1 and G2, and its relationship with cardiac markers and electrocardiographic (ECG) abnormalities. T2DM patients whose estimated glomerular filtration rate (eGFR) was ≥60 mL/min/1.73 m(2) were recruited [n = 276 (165 males), mean age 64 years]. The median level of urinary L-FABP was 6.6 μg/gCr. Urinary L-FABP showed significant correlation with urinary albumin-to-creatinine ratio (ACR) (r = 0.51, p L-FABP ≤8.4 μg/gCr and ACR ≤30 mg/gCr; group 2, L-FABP ≤8.4 μg/gCr and ACR >30 mg/gCr; group 3, L-FABP >8.4 μg/gCr and ACR ≤30 mg/gCr; group 4, L-FABP >8.4 μg/gCr and ACR >30 mg/gCr). Compared with group 1, group 4 was significantly higher in systolic blood pressure, and eGFR using standardized serum cystatin C, high-sensitivity troponin T, and N-terminal pro-brain natriuretic peptide (NT-proBNP). Group 4 had significantly higher level of NT-proBNP than group 3. Groups 2, 3 and 4 showed more ECG abnormalities than group 1. These findings suggest that simultaneous measurement of urinary L-FABP and ACR should be useful to assess cardiovascular damage reflecting on the elevation of cardiac markers and ECG abnormalities in T2DM with CKD G1 and G2.

    Full Text Available Background: Meningitis is defined as inflammation of the membranes that surround the brain and spinal cord and can occur at any age, it is caused by infectious microorganisms include (bacteria, viruses, fungi, and parasites and non infectious include (drugs, carcinoma and inflammatory disorder. Objective: The objective of the present study was to evaluate the value of PCT levels to discriminate between bacterial and non-bacterial meningitis patients. Methods: A total of 40 patients with meningitis admitted to emergency department of Baghdad teaching hospital and pediatrics emergency room in child welfare teaching hospital were followed in this prospective study. Cerebrospinal fluid (CSF sample where collected from 40 patients and serum sample collected from these patients and healthy person. NHS real-time PCR technique using to identified the type of bacteria and serum levels of PCT were measured. Results: The diagnosis of meningitis was based on clinical findings, gram staining, culture, and chemical analysis of CSF. Twenty-eight of patients were diagnosed as bacterial meningitis and the other twelve patients as non-bacterial meningitis. The mean PCT level in patients with bacterial meningitis was 658.00 pg/ml, and the lower level was 21. Pg/ml, while the higher level in patients with non-bacterial meningitis was 11.00 pg/ml (mean level, 5.30 pg/ml. It is clear from the range of serum PCT level that there are no overlapping values seen for serum PCT in both groups. Conclusion: Serum PCT levels can be used in the early diagnosis of bacterial meningitis and is more valuable marker than the other predictive marker. Similarly, they may be useful in differential diagnosis of bacterial and non-bacterial meningitis to assess treatment efficacy.

    Full Text Available Abstract Background Preterm birth is the leading cause of all infant mortality. In 2004, 12.5% of all births were preterm. In order to understand preterm labor, we must first understand normal labor. Since many of the myometrial changes that occur during pregnancy are similar in mice and humans and mouse gestation is short, we have studied the uterine genes that change in the mouse during pregnancy. Here, we used microarray analysis to identify uterine genes in the gravid mouse that are differentially regulated in the cyclooxygenase-1 knockout mouse model of delayed parturition. Methods Gestational d18.0 uteri (n = 4 were collected from pregnant wild-type and cyclooxygenase-1 knockout mice. Part of the uterus was used for frozen sections and RNA was isolated from the remainder. Microarray analysis was performed at the Indiana University School of Medicine Genomic Core and analyzed using the Microarray Data Portal. Northern analysis was performed to confirm microarray data and the genes localized in the gravid uterus by in situ hybridization. Results We identified 277 genes that are abnormally expressed in the gravid d18.0 cyclooxygenase-1 knockout mouse. Nine of these genes are also regulated in the normal murine uterus during the last half of gestation. Many of these genes are involved in the immune response, consistent with an important role of the immune system in parturition. Expression of 4 of these genes; arginase I, IgJ, Tnfrsf9 and troponin; was confirmed by Northern analysis to be mis-regulated during pregnancy in the knockout mouse. In situ hybridization of these genes demonstrated a similar location in the gravid wild-type and Cox-1 knockout mouse uteri. Conclusion To our knowledge, this is the first work to demonstrate the uterine location of these 4 genes in the mouse during late pregnancy. There are several putative transcription factor binding sites that are shared by many of the 9 genes identified here including; estrogen and

    Full Text Available We studied the usefulness of serum procalcitonin (PCT, interleukin-6 (IL-6, lipopolysaccharide binding protein (LBP levels and C-reactive protein (CRP levels, in differentiating between systemic inflammatory response syndrome (SIRS and sepsis in critically ill patients. Methods. In this single centre prospective observational study we included all consecutive patients admitted with SIRS or sepsis to the ICU. Blood samples for measuring CRP, PCT, IL-6 and LBP were taken every day until ICU discharge. Results. A total of 76 patients were included, 32 with sepsis and 44 with SIRS. Patients with sepsis were sicker on admission and had a higher mortality. CRP, PCT, IL-6 and LBP levels were significantly higher in patients with sepsis as compared to SIRS. With PCT levels in the first 24 hours after ICU admission 10 ng/mL, sepsis with bacterial infection was very likely (positive predictive value 88%. PCT was best at discriminating between SIRS and sepsis with the highest area under the ROC curve (0.95, 95% CI 0.90–0.99. Discussion. This study showed that PCT is more useful than LBP, CRP and IL-6 in differentiating sepsis from SIRS.

    Full Text Available Abstract Background Procalcitonin (PCT has emerged as a valuable marker of sepsis. The potential role of PCT in diagnosis and therapy monitoring of intravascular catheter-related bloodstream infections (CRBSI in intensive care unit (ICU is still unclear and was evaluated. Methods Forty-six patients were included in the study, provided they were free of infection upon admission and presented the first episode of suspected CRBSI during their ICU stay. Patients who had developed any other infection were excluded. PCT was measured daily during the ICU hospitalization. Primary endpoint was proven CRBSI. Therapy monitoring as according to infection control was also evaluated. Results Among the 46 patients, 26 were diagnosed with CRBSI. Median PCT on the day of infection suspicion (D0 was 7.70 and 0.10 ng/ml for patients with and without proven CRBSI, respectively (p 0.20 ng/ml of PCT between the D0 and any of the 4 preceding days was associated with a positive predictive value exceeding 96%. PCT concentrations from the D2 to D6 after suspected infection tended to decrease in controlled patients, whereas remained stable in non-controlled subjects. A PCT concentration exceeding 1.5 ng/ml during D3 was associated with lack of responsiveness to therapy (p = 0.028. Conclusions We suggest that PCT could be a helpful diagnostic and prognostic marker of CRBSI in critically ill patients. Both absolute values and variations should be considered.

    This study explores the role of procalcitonin (PCT) in predicting the outcome of sepsis. In a prospective multicentre observational investigation, blood was sampled within 24 h of onset of sepsis in 1156 hospitalised patients; 234 were in the intensive care unit (ICU) at the point of presentation of sepsis while 922 were not. PCT was estimated in serum by the ultrasensitive Kryptor assay in a double-blinded fashion. Among patients outside the ICU, mortality was 8% in those with PCT ≤0.12 ng/mL but 19.9% in those with PCT >0.12 ng/mL [P0.85 ng/mL (P=0.002; OR for death: 2.404; 95% CI: 1.385-4.171). It is concluded that PCT cut-off concentrations can contribute to predicting the outcome of sepsis and might be of particular value in identifying patients who would benefit from ICU admission.

    Objective: To investigate the clinical application of procalcitonin in the diagnosis of severe hand, foot and mouth disease combined with encephalitis. Methods:The research retrospectively analyzed the clinical information of 100 patients hospitalized from June 2014 to June 2015 in our hospital and diagnosed with 2-stage severe hand, foot and mouth disease combined with encephalitis. Peripheral blood WBC count, CRP and PCT levels as well as bacterial etiology such as urine, sputum, blood and feces of all patients were checked on admission. Meanwhile, the cerebrospinal fluid was collected in time through lumbar puncture for routine and biochemical examination. According to the diagnostic results, patients were divided into the virus infection group (n=63 cases) and the bacterial infection group (n=37). Peripheral blood WBC count, CRP and PCT levels of two groups were compared. Lumbar puncture and cerebrospinal fluid examination was used as the“golden standard”for diagnosis of severe hand, foot and mouth disease combined with bacterial encephalitis, and clinical diagnostic efficiency of WBC, CRP and PCT were evaluated by ROC curve. Results:Analysis results showed that the peripheral blood WBC count, CRP and PCT levels of the group with severe hand, foot and mouth disease complicated with bacterial infection were higher than those of the group complicated with virus infection, and the difference was statistically significant. The sensitivity, accuracy, positive predictive value, negative predictive value and Youden index of PCT in the diagnosis of severe hand, foot and mouth disease complicated with bacterial encephalitis were better than those of WBC and CRP, and the difference was statistically significant. AUC (area under the ROC curve) of PCT was 0.931, and was significantly higher than that of WBC (0.735) and CRP (0.774), and the difference was statistically significant. Conclusion:The WBC, CRP and PCT levels significantly increased in patients with severe

    Full Text Available Abstract Background Q fever is a zoonosis distributed worldwide that is caused by Coxiella burnetii infection and the defervescence usually occurs within few days of appropriate antibiotic therapy. Whether the changes of cytokine levels are associated with acute Q fever with persistent fever despite antibiotic therapy had not been investigated before. Case Presentation We report a rare case of acute Q fever granulomatous hepatitis remained pyrexia despite several antibiotic therapy and 6-day course of oral prednisolone. During the 18-month follow-up, the investigation of the serum cytokines profile and procalcitonin (PCT revealed that initially elevated levels of interleukin-2 (IL-2, IL-8, IL-10, and PCT decreased gradually, but the IL-6 remained in low titer. No evidence of chronic Q fever was identified by examinations of serum antibodies against C. burnetii and echocardiography. Conclusions The changes of cytokine levels may be associated with acute Q fever with poor response to treatment and PCT may be an indicator for monitoring the response to treatment.

    Background Currently, there are no biomarkers that can predict the incidence of dengue shock and/or organ failure, although the early identification of risk factors is important in determining appropriate management to reduce mortality. Therefore, we sought to determine the factors associated with dengue shock and/or organ failure and to evaluate the prognostic value of serum procalcitonin (PCT) and peripheral venous lactate (PVL) levels as biomarkers of dengue shock and/or organ failure. Methodology/Principal Findings A prospective observational study was conducted among adults hospitalized for confirmed viral dengue infection at the Hospital for Tropical Diseases in Bangkok, Thailand between October 2013 and July 2015. Data, including baseline characteristics, clinical parameters, laboratory findings, serum PCT and PVL levels, management, and outcomes, were recorded on pre-defined case report forms. Of 160 patients with dengue, 128 (80.0%) patients had dengue without shock or organ failure, whereas 32 (20.0%) patients developed dengue with shock and/or organ failure. Using a stepwise multivariate logistic regression analysis, PCT ≥0.7 ng/mL (odds ratio [OR]: 4.80; 95% confidence interval [CI]: 1.60–14.45; p = 0.005) and PVL ≥2.5 mmol/L (OR: 27.99, 95% CI: 8.47–92.53; p <0.001) were independently associated with dengue shock and/or organ failure. A combination of PCT ≥0.7 ng/mL and PVL ≥2.5 mmol/L provided good prognostic value for predicting dengue shock and/or organ failure, with an area under the receiver operating characteristics curve of 0.83 (95% CI: 0.74–0.92), a sensitivity of 81.2% (95% CI: 63.6–92.8%), and a specificity of 84.4% (95% CI: 76.9–90.2%).

    Hair shaft disorders may lead to brittleness and uncombable hair. In general the hair feels dry and lusterless. Hair shaft abnormalities may occur as localized or generalized disorders. Genetic predisposition or exogenous factors are able to produce and maintain hair shaft abnormalities. In addition to an extensive history and physical examination the most important diagnostic examination to analyze a hair shaft problem is light microscopy. Therapy of hair shaft disorders should focus to the cause. In addition, minimizing traumatic influences to hair shafts, such as dry hair with an electric dryer, permanent waves and dyes is important. A short hair style is more suitable for such patients with hair shaft disorders.

Methods. A total of 102 patients with sepsis were divided into survival group (n=60 and nonsurvival group (n=42 based on 28-day mortality. Serum levels of biomarkers and cytokines were measured on days 1, 3, and 5 after admission to an ICU, meanwhile the acute physiology and chronic health evaluation II (APACHE II and sequential organ failure assessment (SOFA scores were calculated. Results. Serum sTREM-1, PCT, and IL-6 levels of patients in the nonsurvival group were significantly higher than those in the survival group on day 1 (P<0.01. The area under a ROC curve for the prediction of 28 day mortality was 0.792 for PCT, 0.856 for sTREM-1, 0.953 for SOFA score, and 0.923 for APACHE II score. Multivariate logistic analysis showed that serum baseline sTREM-1 PCT levels and SOFA score were the independent predictors of 28-day mortality. Serum PCT, sTREM-1, and IL-6 levels showed a decrease trend over time in the survival group (P<0.05. Serum NT-pro-BNP levels showed the predictive utility from days 3 and 5 (P<0.05. Conclusion. In summary, elevated serum sTREM-1 and PCT levels provide superior prognostic accuracy to other biomarkers. Combination of serum sTREM-1 and PCT levels and SOFA score can offer the best powerful prognostic utility for sepsis mortality.

    ABSTRACT Introduction: To investigate the role of initial procalcitonin (PCT) level as an early predictor of septic shock for the patient with sepsis induced by acute pyelonephritis (APN) secondary to ureteral calculi. Materials and Methods: The data from 49 consecutive patients who met criteria of sepsis due to APN following ureteral stone were collected and divided into two groups: with (n=15) or without (n=34) septic shock. The clinical variables including PCT level for this outcome were retrospectively compared by univariate analysis, followed by multivariable logistic regression model. Results: All subjects had hydronephrosis, and were hospitalized with the mean of 11.8 days (3–42 days). The mean size of the ureteral stones was 7.5mm (3–30mm), and 57% were located in upper ureter. At univariate analysis, patients with septic shock were significantly older, a higher proportion had hypertension, lower platelet count and serum albumin level, higher CRP and PCT level, and higher positive blood culture rate. Multivariate models indicated that lower platelet count and higher PCT level are independent risk factors (p=0.043 and 0.046, respectively). In ROC curve, the AUC was significantly wider in PCT (0.929), compared with the platelet count (0.822, p=0.004). At the cut-off of 0.52ng/mL, the sensitivity and specificity were 86.7% and 85.3%. Conclusion: Our study demonstrated elevated initial PCT levels as an early independent predictor to progress into septic shock in patients with sepsis associated with ureteral calculi. PMID:27256181

    Sonoluminescence is a complex phenomenon, the mechanism of which remains unclear. The present study reveals that an abnormal ionization process is likely to be present in the sonoluminescing bubble. To fit the experimental data of previous studies, we assume that the ionization energies of the molecules and atoms in the bubble decrease as the gas density increases and that the decrease of the ionization energy reaches about 60%–70%as the bubble flashes, which is difficult to explain by using previous models.

    2007-04-01

    The aim of the present work was to assess the value of the semi-quantitative procalcitonine test (PCT) in diagnosis of purulent-septic complications of chest traumas, efficacy of the therapy carried out, and outcome prognosis. For this, 71 patients with chest traumas were enrolled in the study. Concentrations of PCT were assessed in dynamics using an immunochromatographic, semi-quantitative quick test. Semi-quantitative quick PCT test is highly sensitive diagnostic marker that can be used for the assessment of a chest trauma, infectious-septic complication severity, and efficiency of the therapy indicated. Thus, it can be successfully used for monitoring trauma therapy. PCT sensitivity during first 12 hrs of infectious-septic complication development is 2-3-times higher than that of routine methods for laboratory diagnostics, and even more sensitive that IL-6 and CRT, when we are dealing with combined chest traumas. PCT concentration increase is 4-times more frequent in gram-positive bacterial processes than in gram-negative ones. This has to be taken into account, when appropriate antibacterial treatment is selected for restricted infectious-septic complications. PMID:17525495

    In the article, a dual-quantum-dots-labeled (dual-QDs-labeled) lateral flow strip (LFS) method was developed for the simultaneous and rapid quantitative detection of procalcitonin (PCT) and C-reactive protein (CRP) in the blood. Two QD-antibody conjugates with different fluorescence emission spectra were produced and sprayed on the LFS to capture PCT and CRP in the blood. Furthermore, a double antibody sandwich method for PCT and, meanwhile, a competitive inhibition method for CRP were employed in the LFS. For PCT and CRP in serum assayed by the dual-QDs-labeled LFS, their detection sensitivities reached 0.1 and 1 ng/mL, respectively, and their linear quantitative detection ranges were from 0.3 to 200 ng/mL and from 50 to 250 μg/mL, respectively. There was little evidence that the PCT and CRP assays would be interfered with each other. The correlations for testing CRP and PCT in clinical samples were 99.75 and 97.02 %, respectively, between the dual-QDs-labeled LFS we developed and commercial methods. The rapid quantification of PCT and CRP on dual-QDs-labeled LFS is of great clinical value to distinguish inflammation, bacterial infection, or viral infection and to provide guidance for the use of antibiotics or other medicines.

  18. The First Trimester Gravid Serum Regulates Procalcitonin Expression in Human Macrophages Skewing Their Phenotype In Vitro

    Full Text Available Procalcitonin (PCT is one of the best diagnostic and prognostic markers in clinical practice, widely used to evaluate the evolution of bacterial infections. Although it is mainly produced by thyroid, during sepsis almost all the peripheral tissues are involved in PCT production. Parenchymal cells have been suggested as the main source of PCT expression; however the contribution of macrophages is not clear yet. In response to environmental cues, tissue macrophages acquire distinct functional phenotypes, ranging from proinflammatory (M1 to anti-inflammatory (M2 phenotype. Macrophages at the fetal-maternal interface show immunosuppressive M2-like activities required for the maintenance of immunological homeostasis during pregnancy. This study aims to clarify the ability to synthesise PCT of fully differentiated (M0, polarized (M1/M2 macrophages and those cultured either in the presence of first trimester gravid serum (GS or pregnancy hormones. We found out that M1 macrophages upregulate PCT expression following LPS stimulation compared to M0 and M2. The GS downregulates PCT expression in macrophages, skewing them towards an M2-like phenotype. This effect seems only partially mediated by the hormonal milieu. Our findings strengthen the key role of macrophages in counteracting inflammatory stimuli during pregnancy, suggesting PCT as a possible new marker of M1-like macrophages.

    Full Text Available Introduction. Serum procalcitonin (PCT diagnosed sepsis in critically ill patients; however, its prediction for survival is not well established. We evaluated the prognostic value of dynamic changes of PCT in sepsis patients. Methods. A prospective observational study was conducted in adult ICU. Patients with systemic inflammatory response syndrome (SIRS were recruited. Daily PCT were measured for 3 days. 48 h PCT clearance (PCTc-48 was defined as percentage of baseline PCT minus 48 h PCT over baseline PCT. Results. 95 SIRS patients were enrolled (67 sepsis and 28 noninfectious SIRS. 40% patients in the sepsis group died in hospital. Day 1-PCT was associated with diagnosis of sepsis (AUC 0.65 (95% CI, 0.55 to 0.76 but was not predictive of mortality. In sepsis patients, PCTc-48 was associated with prediction of survival (AUC 0.69 (95% CI, 0.53 to 0.84. Patients with PCTc-48 > 30% were independently associated with survival (HR 2.90 (95% CI 1.22 to 6.90. Conclusions. PCTc-48 is associated with prediction of survival in critically ill patients with sepsis. This could assist clinicians in risk stratification; however, the small sample size, and a single-centre study, may limit the generalisability of the finding. This would benefit from replication in future multicentre study.

    Full Text Available Objective: Chronic periodontitis is the most common form of periodontal disease. Changes in biomarkers seem to be associated with the disease progression. Procalcitonin (PCT is one of these biomarkers that are altered during infection. This study was established to investigate the relationship between periodontitis as an infectious disease and salivary PCT. Materials and Methods: This case-control study was performed on 30 patients with generalized chronic periodontitis and 30 health individuals as control group who were referred to Dental School, Jundishapur University of Ahvaz, Ahvaz, Iran at Feb to Apr 2014. The saliva samples were collected and analyzed by the enzyme-linked immunosorbent assay (ELISA method. Data analysis was performed using t test with the SPSS (SPSS Inc., Chicago, IL, USA version 13. Results: In both groups, age and sex distribution values were not significantly different. The concentrations of salivary PCT in controls and patients ranged from 0.081 pg/ mL to 0.109 pg/mL and from 0.078 pg/mL to 0.114 pg/mL, respectively. The statistically significant differences between the two groups were not observed (P=0.17. Conclusion: It seems that salivary PCT concentration is not affected by disease progression. Therefore, PCT is not a valuable marker for the existence of periodontal disease.

    In the article, a dual-quantum-dots-labeled (dual-QDs-labeled) lateral flow strip (LFS) method was developed for the simultaneous and rapid quantitative detection of procalcitonin (PCT) and C-reactive protein (CRP) in the blood. Two QD-antibody conjugates with different fluorescence emission spectra were produced and sprayed on the LFS to capture PCT and CRP in the blood. Furthermore, a double antibody sandwich method for PCT and, meanwhile, a competitive inhibition method for CRP were employed in the LFS. For PCT and CRP in serum assayed by the dual-QDs-labeled LFS, their detection sensitivities reached 0.1 and 1 ng/mL, respectively, and their linear quantitative detection ranges were from 0.3 to 200 ng/mL and from 50 to 250 μg/mL, respectively. There was little evidence that the PCT and CRP assays would be interfered with each other. The correlations for testing CRP and PCT in clinical samples were 99.75 and 97.02 %, respectively, between the dual-QDs-labeled LFS we developed and commercial methods. The rapid quantification of PCT and CRP on dual-QDs-labeled LFS is of great clinical value to distinguish inflammation, bacterial infection, or viral infection and to provide guidance for the use of antibiotics or other medicines.

    AIM: This report gives a comprehensive overview of ultrasonography of splenic abnormalities. Certain ultrasonic features are also discussed with pathologic correlation.METHODS: We review the typical ultrasonic characteristics of a wide range of splenic lesions, illustrating them with images obtained in our institution from 2000 to 2003.One hundred and three patients (47 men, 56 women),with a mean age of 54 years (range 9-92 years), were found to have an abnormal ultrasonic pattern of spleen.RESULTS: We describe the ultrasonic features of various splenic lesions such as accessory spleen, splenomegaly,cysts, cavernous hemangiomas, lymphomas, abscesses,metastatic tumors, splenic infarctions, hematomas, and rupture, based on traditional gray-scale and color Doppler sonography.CONCLUSION: Ultrasound is a widely available, noninvasive,and useful means of diagnosing splenic abnormalities. A combination of ultrasonic characteristics and clinical data may provide an accurate diagnosis. If the US appearance alone is not enough, US may also be used to guide biopsy of suspicious lesions.

    Full Text Available BACKGROUND: Management of febrile neutropenic episodes (FE is challenged by lacking microbiological and clinical documentation of infection. We aimed at evaluating the utility of monitoring blood procalcitonin (PCT in FE for initial diagnosis of infection and reassessment in persistent fever. METHODS: PCT kinetics was prospectively monitored in 194 consecutive FE (1771 blood samples: 65 microbiologically documented infections (MDI, 33.5%; 49 due to non-coagulase-negative staphylococci, non-CNS, 68 clinically documented infections (CDI, 35%; 39 deep-seated, and 61 fever of unexplained origin (FUO, 31.5%. RESULTS: At fever onset median PCT was 190 pg/mL (range 30-26'800, without significant difference among MDI, CDI and FUO. PCT peak occurred on day 2 after onset of fever: non-CNS-MDI/deep-seated-CDI (656, 80-86350 vs. FUO (205, 33-771; p500 pg/mL distinguished non-CNS-MDI/deep-seated-CDI from FUO with 56% sensitivity and 90% specificity. PCT was >500 pg/ml in only 10% of FUO (688, 570-771. A PCT peak >500 pg/mL (1196, 524-11950 occurred beyond 3 days of persistent fever in 17/21 (81% invasive fungal diseases (IFD. This late PCT peak identified IFD with 81% sensitivity and 57% specificity and preceded diagnosis according to EORTC-MSG criteria in 41% of cases. In IFD responding to therapy, median days to PCT <500 pg/mL and defervescence were 5 (1-23 vs. 10 (3-22; p = 0.026, respectively. CONCLUSION: While procalcitonin is not useful for diagnosis of infection at onset of neutropenic fever, it may help to distinguish a minority of potentially severe infections among FUOs on day 2 after onset of fever. In persistent fever monitoring procalcitonin contributes to early diagnosis and follow-up of invasive mycoses.

    Background Both procalcitonin (PCT) and soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) have been investigated separately as indicators of infection in patients with autoimmune diseases. Our study simultaneously evaluated both PCT and sTREM-1 along with C-reactive protein (CRP) in febrile patients with autoimmune diseases. Methods Fifty-nine patients were enrolled in the study. The patients were categorized into the infection group (n = 24) or the disease flare group (n = 35). sTREM-1, PCT and CRP concentrations at fever onset were compared between the two groups of patients. Results sTREM-1 and CRP did not differ between the two groups. PCT [median (range), ng/ml] was higher in the infection group than in the disease flare group [0.53 (0.02–12.85) vs. 0.12 (0.02–19.23), p = 0.001]. The area under the receiver-operating characteristic (ROC) for diagnosis of infection was 0.75 for PCT (p = 0.001), 0.63 for CRP (p = 0.09) and 0.52 for sTREM-1 (p = 0.79). Using 0.2 ng/ml as the cutoff value for PCT, sensitivity was 0.75 and specificity was 0.77. Negative predictive values for PCT were 92%, 87% and 82% for a prevalence of infection of 20%, 30%, and 40%, respectively. Neither immunosuppressants nor biomodulators affected the level of the three biomarkers. However, in patients treated with corticosteroids, the levels of sTREM-1 and CRP were significantly decreased compared with the untreated patients. Conclusions Setting PCT at a lower cutoff value could provide useful information on excluding infection in febrile patients with autoimmune diseases. The possible effect of corticosteroids on the level of sTREM-1 as an infection marker deserves further study. PMID:27096761

    Sonoluminescence is a complex phenomenon, the mechanism of which remains unclear. The present study reveals that an abnormal ionization process is likely to be present in the sonoluminescing bubble. To fit the experimental data of previous studies, we assume that the ionization energies of the molecules and atoms in the bubble decrease as the gas density increases and that the decrease of the ionization energy reaches about 60%-70% as the bubble flashes, which is difficult to explain by using previous models.

    Full Text Available BACKGROUND: Early predictors for the development of stroke-associated infection may identify patients at high risk and reduce post-stroke infection and mortality. METHODS: In 383 prospectively enrolled acute stroke patients we assessed time point and type of post-stroke infections (i.e. pneumonia, urinary tract infection (UTI other infection (OI. Blood samples were collected on admission, and days 1, and 3 to assess white blood cells (WBC, monocytes, C-reactive protein (CRP, procalcitonin (PCT, and copeptin. To determine the magnitude of association with the development of infections, odds ratios (OR were calculated for each prognostic blood marker. The discriminatory ability of different predictors was assessed, by calculating area under the receiver operating characteristic curves (AUC. Prognostic models including the three parameters with the best performance were identified. RESULTS: Of 383 patients, 66 (17.2% developed an infection after onset of stroke. WBC, CRP, copeptin and PCT were all independent predictors of any infection, pneumonia and UTI developed at least 24 hours after measurements. The combination of the biomarkers WBC, CRP and copeptin (AUC: 0.92 and WBC, CRP and PCT (AUC: 0.90 showed a better predictive accuracy concerning the development of pneumonia during hospitalization compared to each marker by itself (p-Wald <0.0001. CONCLUSION: Among ischemic stroke patients, copeptin, PCT, WBC and CRP measured on admission were predictors of infection in general, and specifically for pneumonia and UTI within 5 days after stroke. The combination of these biomarkers improved the prediction of patients who developed an infection.

    Full Text Available Abstract Background: Lower respiratory tract infections like acute bronchitis, exacerbated chronic obstructive pulmonary disease and community-acquired pneumonia are often unnecessarily treated with antibiotics, mainly because of physicians' difficulties to distinguish viral from bacterial cause and to estimate disease-severity. The goal of this trial is to compare medical outcomes, use of antibiotics and hospital resources in a strategy based on enforced evidence-based guidelines versus procalcitonin guided antibiotic therapy in patients with lower respiratory tract infections. Methods and design: We describe a prospective randomized controlled non-inferiority trial with an open intervention. We aim to randomize over a fixed recruitment period of 18 months a minimal number of 1002 patients from 6 hospitals in Switzerland. Patients must be >18 years of age with a lower respiratory tract infections Discussion: Use of and prolonged exposure to antibiotics in lower respiratory tract infections is high. The proposed trial investigates whether procalcitonin-guidance may safely reduce antibiotic consumption along with reductions in hospitalization costs and antibiotic resistance. It will additionally generate insights for improved prognostic assessment of patients with lower respiratory tract infections. Trial registration: ISRCTN95122877

    Introduction: visual analysis is widely used to interpret regional cerebral blood flow (rCBF) SPECT images in clinical practice despite its limitations. Automated methods are employed to investigate between-group rCBF differences in research studies but have rarely been explored in individual analyses. Objectives: to compare visual inspection by nuclear physicians with the automated statistical parametric mapping program using a SPECT dataset of patients with neurological disorders and normal control images. Methods: using statistical parametric mapping, 14 SPECT images from patients with various neurological disorders were compared individually with a databank of 32 normal images using a statistical threshold of p<0.05 (corrected for multiple comparisons at the level of individual voxels or clusters). Statistical parametric mapping results were compared with visual analyses by a nuclear physician highly experienced in neurology (A) as well as a nuclear physician with a general background of experience (B) who independently classified images as normal or altered, and determined the location of changes and the severity. Results: of the 32 images of the normal databank, 4 generated maps showing rCBF abnormalities (p<0.05, corrected). Among the 14 images from patients with neurological disorders, 13 showed rCBF alterations. Statistical parametric mapping and physician A completely agreed on 84.37% and 64.28% of cases from the normal databank and neurological disorders, respectively. The agreement between statistical parametric mapping and ratings of physician B were lower (71.18% and 35.71%, respectively). Conclusion: statistical parametric mapping replicated the findings described by the more experienced nuclear physician. This finding suggests that automated methods for individually analyzing rCBF SPECT images may be a valuable resource to complement visual inspection in clinical practice. (author)

    Full Text Available The aim of this study is to increase awareness of rare presentations, diagnostic difficulties alongside management of conductive hearing loss and ossicular abnormalities. We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and lack of connection between the stapes superstructure and footplate. The footplate was fixed. Stapedotomy and stapes prosthesis insertion resulted in closure of the air-bone gap by 50 dB. A review of world literature was performed using MedLine. Middle ear ossicular discontinuity can result in significant conductive hearing loss. This can be managed effectively with surgery to help restore hearing. However, some patients may not be suitable or decline surgical intervention and can be managed safely conservatively.

    Although procalcitonin (PCT) is a valid marker for early diagnosis of bacterial infections, it is unclear whether its accuracy in predicting bacterial infections is affected by impaired liver function. This study aimed to assess the impact of compromised liver function on the diagnostic value of PCT.This retrospective study was conducted between January 2013 and May 2015. A total of 324 patients with chronic liver disease were enrolled. Routine laboratory measurements and PCT were performed. Patients were divided into 3 groups according to clinical diagnosis: chronic hepatitis (group 1), decompensated cirrhosis (group 2), and acute-on-chronic liver failure/chronic liver failure (group 3). The correlation between PCT and liver function was analyzed. The area under the receiver operating characteristic (AUCROC) curve of PCT was analyzed according to infection status and liver function.PCT was more accurate than white blood cell count (P PCT had a moderate positive correlation with serum total bilirubin (TBIL) (r = 0.592), and a weak correlation with model for end-stage liver disease score (r = 0.483) and international normalized ratio (r = 0.389). The AUCROC and optimum thresholds of PCT and for predicting bacterial infections at different levels of TBIL were 0.907 (95% CI 0.828-0.958) and 0.38 ng/mL, respectively, for TBIL PCT was a valuable marker of bacterial infection in patients with chronic liver diseases. TBIL affected PCT threshold, so different cut-offs should be used according to different TBIL values. PMID:27472699

    Full Text Available Sepsis is a major cause of mortality and morbidity in critically ill patients. Procalcitonin (PCT and C-reactive protein (CRP are the most frequently used biomarkers in sepsis. We investigated changes in PCT and CRP concentrations in critically ill patients with sepsis to determine which biochemical marker better predicts outcome. We retrospectively analyzed 171 episodes in 157 patients with severe sepsis and septic shock who were admitted to the Samsung Medical Center intensive care unit from March 2013 to February 2014. The primary endpoint was patient outcome within 7 days from ICU admission (treatment failure. The secondary endpoint was 28-day mortality. Severe sepsis was observed in 42 (25% episodes from 41 patients, and septic shock was observed in 129 (75% episodes from 120 patients. Fifty-five (32% episodes from 42 patients had clinically-documented infection, and 116 (68% episodes from 99 patients had microbiologically-documented infection. Initial peak PCT and CRP levels were not associated with treatment failure and 28-day mortality. However, PCT clearance (PCTc and CRP (CRPc clearance were significantly associated with treatment failure (p = 0.027 and p = 0.030, respectively and marginally significant with 28-day mortality (p = 0.064 and p = 0.062, respectively. The AUC for prediction of treatment success was 0.71 (95% CI, 0.61-0.82 for PCTc and 0.71 (95% CI, 0.61-0.81 for CRPc. The AUC for survival prediction was 0.77 (95% CI, 0.66-0.88 for PCTc and 0.77 (95% CI, 0.67-0.88 for CRPc. Changes in PCT and CRP concentrations were associated with outcomes of critically ill septic patients. CRP may not be inferior to PCT in predicting outcome in these patients.

    Abnormal uterine bleeding (AUB) is a common and debilitating condition with high direct and indirect costs. AUB frequently co-exists with fibroids, but the relationship between the two remains incompletely understood and in many women the identification of fibroids may be incidental to a menstrual bleeding complaint. A structured approach for establishing the cause using the Fédération International de Gynécologie et d'Obstétrique (FIGO) PALM-COEIN (Polyp, Adenomyosis, Leiomyoma, Malignancy (and hyperplasia), Coagulopathy, Ovulatory disorders, Endometrial, Iatrogenic and Not otherwise classified) classification system will facilitate accurate diagnosis and inform treatment options. Office hysteroscopy and increasing sophisticated imaging will assist provision of robust evidence for the underlying cause. Increased availability of medical options has expanded the choice for women and many will no longer need to recourse to potentially complicated surgery. Treatment must remain individualised and encompass the impact of pressure symptoms, desire for retention of fertility and contraceptive needs, as well as address the management of AUB in order to achieve improved quality of life.

    Cardiac rhythm abnormalities in the context of epilepsy are a well-known phenomenon. However, they are under-recognized and often missed. The pathophysiology of these events is unclear. Bradycardia and asystole are preceded by seizure onset suggesting ictal propagation into the cortex impacting cardiac autonomic function, and the insula and amygdala being possible culprits. Sudden unexpected death in epilepsy (SUDEP) refers to the unanticipated death of a patient with epilepsy not related to status epilepticus, trauma, drowning, or suicide. Frequent refractory generalized tonic-clonic seizures, anti-epileptic polytherapy, and prolonged duration of epilepsy are some of the commonly identified risk factors for SUDEP. However, the most consistent risk factor out of these is an increased frequency of generalized tonic-clonic seizures (GTC). Prevention of SUDEP is extremely important in patients with chronic, generalized epilepsy. Since increased frequency of GTCS is the most consistently reported risk factor for SUDEP, effective seizure control is the most important preventive strategy. PMID:27347227

    In this paper the similarities between normal and abnormal behaviour are emphasized and selected aspects of communication, normal and aberrant, between persons are explored. Communication in a social system may be verbal or non-verbal: one person's actions cause a response in another person. This response may be cognitive, behavioural or physiological. Communication may be approached through the individual, the social situation or social interaction. Psychoanalysis approaches the individual in terms of the coded communications of psychoneurotic symptoms or psychotic behaviour; the humanist-existential approach is concerned more with emotional expression. Both approaches emphasize the development of individual identity. The interaction between persons and their social background is stressed. Relevant are sociological concepts such as illness behaviour, stigma, labelling, institutionalization and compliance. Two approaches to social interactions are considered: the gamesplaying metaphor, e.g. back pain as a psychosocial manipulation--the 'pain game'; and the 'spiral of reciprocal perspectives' which emphasizes the interactional complexities of social perceptions. Communicatory aspects of psychological treatments are noted: learning a particular metaphor such as 'resolution' of the problem (psychotherapy), learning more 'rewarding' behaviour (learning theory) or learning authenticity or self-actualization (humanist-existential).

    Full Text Available Abstract Background The usefulness of procalcitonin (PCT measurement in critically ill medical patients with suspected nosocomial infection is unclear. The aim of the study was to assess PCT value for the early diagnosis of bacterial nosocomial infection in selected critically ill patients. Methods An observational cohort study in a 15-bed intensive care unit was performed. Seventy patients with either proven (n = 47 or clinically suspected but not confirmed (n = 23 nosocomial infection were included. Procalcitonin measurements were obtained the day when the infection was suspected (D0 and at least one time within the 3 previous days (D-3 to D0. Patients with proven infection were compared to those without. The diagnostic value of PCT on D0 was determined through the construction of the corresponding receiver operating characteristic (ROC curve. In addition, the predictive value of PCT variations preceding the clinical suspicion of infection was assessed. Results PCT on D0 was the best predictor of proven infection in this population of ICU patients with a clinical suspicion of infection (AUROCC = 0.80; 95% CI, 0.68–0.91. Thus, a cut-off value of 0.44 ng/mL provides sensitivity and specificity of 65.2% and 83.0%, respectively. Procalcitonin variation between D-1 and D0 was calculated in 45 patients and was also found to be predictive of nosocomial infection (AUROCC = 0.89; 95% CI, 0.79–0.98 with a 100% positive predictive value if the +0.26 ng/mL threshold value was applied. Comparable results were obtained when PCT variation between D-2 and D0, or D-3 and D0 were considered. In contrast, CRP elevation, leukocyte count and fever had a poor predictive value in our population. Conclusion PCT monitoring could be helpful in the early diagnosis of nosocomial infection in the ICU. Both absolute values and variations should be considered and evaluated in further studies.

    Background It has recently been suggested that serum procalcitonin (PCT) is of value in the diagnosis of neonatal sepsis, with varying results. The aim of this prospective multicenter study was to assess the usefulness of PCT as a marker of neonatal sepsis of nosocomial origin. Methods One hundred infants aged between 4 and 28 days of life admitted to the Neonatology Services of 13 acute-care teaching hospitals in Spain over 1-year with clinical suspicion of neonatal sepsis of nosocomial origin were included in the study. Serum PCT concentrations were determined by a specific immunoluminometric assay. The reliability of PCT for the diagnosis of nosocomial neonatal sepsis at the time of suspicion of infection and at 12–24 h and 36–48 h after the onset of symptoms was calculated by receiver-operating characteristics (ROC) curves. The Youden's index (sensitivity + specificity - 1) was used for determination of optimal cutoff values of the diagnostic tests in the different postnatal periods. Sensitivity, specificity, and the likelihood ratio of a positive and negative result with the 95% confidence interval (CI) were calculated. Results The diagnosis of nosocomial sepsis was confirmed in 61 neonates. Serum PCT concentrations were significantly higher at initial suspicion and at 12–24 h and 36–48 h after the onset of symptoms in neonates with confirmed sepsis than in neonates with clinically suspected but not confirmed sepsis. Optimal PCT thresholds according to ROC curves were 0.59 ng/mL at the time of suspicion of sepsis (sensitivity 81.4%, specificity 80.6%); 1.34 ng/mL within 12–24 h of birth (sensitivity 73.7%, specificity 80.6%), and 0.69 ng/mL within 36–48 h of birth (sensitivity 86.5%, specificity 72.7%). Conclusion Serum PCT concentrations showed a moderate diagnostic reliability for the detection of nosocomial neonatal sepsis from the time of suspicion of infection. PCT is not sufficiently reliable to be the sole marker of sepsis, but would be

    Full Text Available Background: In 14 randomized controlled studies to date, a procalcitonin (PCT-based algorithm has been proven to markedly reduce the use of antibiotics along with an unimpaired high safety and low complication rates in patients with lower respiratory tract infections (LRTIs. However, compliance with the algorithm and safety out of controlled study conditions has not yet been sufficiently investigated. Methods: We performed a prospective international multicenter observational post-study surveillance of consecutive adults with community-acquired LRTI in 14 centers (Switzerland (n = 10, France (n = 3 and the United States (n = 1. Results: Between September 2009 and November 2010, 1,759 patients were enrolled (median age 71; female sex 44.4%. 1,520 (86.4% patients had a final diagnosis of LRTI (community-acquired pneumonia (CAP, 53.7%; acute exacerbation of chronic obstructive pulmonary disease (AECOPD, 17.1%; and acute bronchitis, 14.4%. Compliance with the PCT-guided therapy (overall 68.2% was highest in patients with bronchitis (81.0% vs. AECOPD, 70.1%; CAP, 63.7%; p < 0.001, outpatients (86.1% vs. inpatients, 65.9%; p < 0.001 and algorithm-experienced centers (82.5% vs. algorithm-naive, 60.1%; p < 0.001 and showed significant geographical differences. The initial decision about the antibiotic therapy was based on PCT value in 72.4%. In another 8.6% of patients, antibiotics were administered despite low PCT values but according to predefined criteria. Thus, the algorithm was followed in 81.0% of patients. In a multivariable Cox hazard ratio model, longer antibiotic therapy duration was associated with algorithm-non-compliance, country, hospitalization, CAP vs. bronchitis, renal failure and algorithm-naïvety of the study center. In a multivariable logistic regression complications (death, empyema, ICU treatment, mechanical ventilation, relapse, and antibiotic-associated side effects were significantly associated with increasing CURB65-Score, CAP

    Systemic abnormalities often occur in patients with liver disease. In particular, cardiopulmonary or renal diseases accompanied by advanced liver disease can be serious and may determine the quality of life and prognosis of patients. Therefore, both hepatologists and non-hepatologists should pay attention to such abnormalities in the management of patients with liver diseases.

  12. Abnormal pressure in hydrocarbon environments

    Abnormal pressures, pressures above or below hydrostatic pressures, occur on all continents in a wide range of geological conditions. According to a survey of published literature on abnormal pressures, compaction disequilibrium and hydrocarbon generation are the two most commonly cited causes of abnormally high pressure in petroleum provinces. In young (Tertiary) deltaic sequences, compaction disequilibrium is the dominant cause of abnormal pressure. In older (pre-Tertiary) lithified rocks, hydrocarbon generation, aquathermal expansion, and tectonics are most often cited as the causes of abnormal pressure. The association of abnormal pressures with hydrocarbon accumulations is statistically significant. Within abnormally pressured reservoirs, empirical evidence indicates that the bulk of economically recoverable oil and gas occurs in reservoirs with pressure gradients less than 0.75 psi/ft (17.4 kPa/m) and there is very little production potential from reservoirs that exceed 0.85 psi/ft (19.6 kPa/m). Abnormally pressured rocks are also commonly associated with unconventional gas accumulations where the pressuring phase is gas of either a thermal or microbial origin. In underpressured, thermally mature rocks, the affected reservoirs have most often experienced a significant cooling history and probably evolved from an originally overpressured system.

    Inflammatory markers have been associated with functional outcome and mortality of stroke. We investigated the changes in procalcitonin (PCT) and high-sensitivity C-reactive protein (Hs-CRP) levels during the acute period of ischemic stroke and evaluated the relationship between these levels and the long-term functional outcome and mortality. We prospectively studied 376 patients with acute ischemic stroke (AIS) who were admitted within 24 h after the onset of symptoms. PCT, Hs-CRP, and NIH Stroke Scale (NIHSS) were measured at the time of admission. Long-term functional outcome were measured by modified Rankin scale (mRS) at 1 year after admission. The correlations between the levels of PCT, Hs-CRP, and mortality at 1 year after stroke onset were analyzed. Patients with poor with functional outcome and non-survivors had significantly increased PCT and Hs-CRP levels on admission. Multivariate logistic regression analysis showed that PCT was an independent prognostic marker of 1-year functional outcome and death [odds ratio (OR) 2.33 (95% CI, 1.33-3.44) and 3.11 (2.02-4.43), respectively, P < 0.0001 for both, adjusted for age, NIHSS, other predictors, and vascular risk factors] in patients with AIS. The area under the receiver operating characteristic curve of PCT was 0.77 (95% CI, 0.72-0.83) for functional outcome and 0.88 (95% CI, 0.84-0.93) for mortality. PCT improved the area under the receiver operating characteristic curve of the NIHSS score for functional outcome from 0.74 (95% CI, 0.66-0.81) to 0.85 (95% CI, 0.76-0.92; P < 0.0001) and for mortality from 0.77 (95% CI, 0.70-0.83) to 0.94 (95% CI, 0.89-0.97; P < 0.0001). Serum level of PCT at admission was an independent predictor of long-term functional outcome and mortality after ischemic stroke in Chinese sample. PMID:25650122

    Background Septic shock caused by bacteremia is a life-threatening infection whose prognosis is highly dependent on early recognition and appropriate treatment.Procalcitonin (PCT) has been shown to accurately and quickly distinguish bacteremia from noninfectious inflammatory states in critically severe patients.However,the extent of PCT magnitude elevation according to the Gram stain result in elderly patients with coronary heart disease (CHD) at the onset of septic shock caused by bacteremia varies,and has not been clearly elucidated.Methods The medical records of advanced age (non-neutropenic) patient with CHD and septic shock between Mar 2013 and Jun 2015 who had bacteremia caused by either Gram-positive (GP) bacteria or Gram-negative (GN) bacteria were reviewed,and the levels of PCT,C-reactive (CRP) protein and white blood cells count (WBC) in both groups were analyzed.Results 75 episodes of either GN bacteremia (n =40) or GP bacteremia (n =35) were enrolled.PCT levels were found to be markedly higher in patients with GN bacteremia than in those with GP bacteremia [(8.93 ± 17.58) vs.(64.42 ± 58.56) ng/L (P < 0.001)],whereas there was no significant difference in CRP and WBC (P > 0.05).Moreover,a high PCT level was found to be independently associated with GN bacteremia in this study population.A PCT level of 19.69 ng/mL yielded a 72.5% sensitivity,a 91.4% specificity,an 8.43 positive likelihood ratio and a 0.30 negative likelihood ratio for GN-related bacteremia in the study cohort [AUROCC =0.870 (0.041),95% CI (0.790-0.949)].Conclusion In an elderly patient (non-neutropenic)with CHD and septic shock,GN bacteremia could be associated with higher PCT values than those found in GP bacteremia (PCT > 19.69 ng/mL).

    降钙素原是一种炎症标志物,其在多种临床感染性疾病中均显示出高度的特异性及敏感性。鉴于传统的腹膜透析相关性腹膜炎的检测手段均具有一定的局限性,国内外学者开始倾向于将降钙素原纳入腹膜透析相关性腹膜炎的诊断指标,研究表明腹膜透析相关性腹膜炎患者的血清降钙素原水平显著升高。因此,降钙素原可以作为腹膜透析相关性腹膜炎患者在诊断和治疗过程中的重要检测指标,其对腹膜透析相关性腹膜炎的指导意义值得进一步探索。%Procalcitonin has been clearly specified as an infection marker for many clinical diagnosis of bacterial infections with high sensitivity and specificity .In view of some certain limitations on traditional diag-nostic standards of peritoneal dialysis related peritonitis, both domestic and foreign scholars tended to intro-duce procalcitonin as one of peritoneal dialysis related peritonitis indicators .A large number of studies showed that patients suffering from peritoneal dialysis related peritonitis gained significantly higher concentra-tion of serum procalcitonin.Therefore, procalcitonin can be used as an important detection index in the diag-nosis and treatment of peritoneal dialysis related peritonitis,the guiding significance of which deserves further exploration.

    Background Fever is a common symptom in the emergency department(ED). Fever can be caused by bacterial infections, which are treated with antibiotics. Often, bacterial infections cannot be ruled out in the ED using standard diagnostics, and empiric antibiotic treatment is started. Procalcitonin(PCT) is a biomarker for bacterial infections, but its role in an undifferentiated ED population remains unclear. We hypothesize that PCT-guided therapy may reduce antibiotics prescription in undifferen...

    Full Text Available Spinal cord injury without radiological abnormality is rare in adults. Below we present a case report of 20 yrs old male with isolated cervical cord injury, without accompanying vertebral dislocation or fracture involving the spinal canal rim. He fell down on plain and smooth ground while carrying 40 kg weight overhead and developed quadriparesis with difficulty in respiration. Plain radiographs of the neck revealed no fractures or dislocations. MRI showed bulky spinal cord and an abnormal hyper intense signal on the T2W image from C2 vertebral body level to C3/4 intervertebral disc level predominantly in the anterior aspect of the cord The patient was managed conservatively with head halter traction and invasive ventilatory support for the initial 7 days period in the ICU. In our patient recovery was good and most of the neurological deficit improved over 4 weeks with conservative management.

    In patients with Raynaud's phenomenon (RP), the role of medical history, capillaroscopy, and autoantibodies in order to provide an early diagnosis of connective tissue disease (CTD) were examined. 115 consecutive adults with uni-, bi-, or triphasic colour changes of the fingers were studied. RP was bilateral in 92.7% of patients. The middle finger was significantly more affected. A lack of association between fingers affected by RP and fingers with capillary abnormalities was observed OR = 0.75 (0.34-1.66). RP with the cyanotic phase had a higher risk at capillaroscopy to have hemorrhages OR = 4.46 (1.50-13.30) and giant capillaries OR = 24.85 (1.48-417.44). The thumb and triphasic involvement have an OR of 1.477 and 1.845, respectively. RP secondary to systemic sclerosis (SSc) had greater value of VAS pain (p = 0.011). The presence of anti-centromere antibodies was significantly associated with a higher risk of SSc (p blanching of the fingers, and among these, 27% was diagnosed as having an overt or suspected CTD. Markers of a potential development of CTDs include severe RP symptoms, positive autoantibodies, and capillary abnormalities. These data support the proposal to not discharge patients with uniphasic blanching of the fingers to avoid missing the opportunity of an early diagnosis.

  6. Memetics clarification of abnormal behavior

    AIM: Biological medicine is hard to fully and scientifically explain the etiological factor and pathogenesis of abnormal behaviors; while, researches on philosophy and psychology (including memetics) are beneficial to better understand and explain etiological factor and pathogenesis of abnormal behaviors. At present, the theory of philosophy and psychology is to investigate the entity of abnormal behavior based on the views of memetics.METHODS: Abnormal behavior was researched in this study based on three aspects, including instinctive behavior disorder, poorly social-adapted behavior disorder and mental or body disease associated behavior disorder. Most main viewpoints of memetics were derived from "The Meme Machine", which was written by Susan Blackmore. When questions about abnormal behaviors induced by mental and psychological diseases and conduct disorder of teenagers were discussed, some researching achievements which were summarized by authors previously were added in this study, such as aggressive behaviors, pathologically aggressive behaviors, etc.RESULTS: The abnormal behaviors mainly referred to a part of people's substandard behaviors which were not according with the realistic social environment, culture background and the pathologic behaviors resulted from people's various psychological diseases. According to the theory of "meme", it demonstrated that the relevant behavioral obstacles of various psychological diseases, for example, the unusual behavior of schizophrenia, were caused, because the old meme was destroyed thoroughly but the new meme was unable to establish; psychoneurosis and personality disorder were resulted in hard establishment of meme; the behavioral obstacles which were ill-adapted to society, for example, various additional and homosexual behaviors, were because of the selfish replications and imitations of "additional meme" and "homosexual meme"; various instinct behavioral and congenital intelligent obstacles were not significance

    Full Text Available Background: AUB is a common but complicated clinical presentation and occurs in 15-20% of women between menarche to menopause and significantly affects the women's health. Women with thyroid dysfunction often have menstrual irregularities, infertility and increased morbidity during pregnancy. The objective of present study is to find the correlation between thyroid disorders and AUB in perimenopausal women attending gynecology OPD. Methods: In the present study, fifty five patients with AUB were included and were evaluated for the cause including thyroid abnormality. Thyroid function tests were done in all patients. Results: Among 55 patients, 12 patients were diagnosed as hypothyroidism and 7 as hyperthyroidism, women with AUB 36 (65.4% were euthyroid. Among 19 women with thyroid abnormality, heavy menstrual bleeding was seen in 8 (42% women, 6 (31.57% had polymenorrhagia, 5 (26.31% had oligomenorrhoea. The frequent menstrual abnormality in women with hypothyroidism (12 women was heavy menstrual bleeding in 5 (41.6% women, 3 (25% had oligomennorhoea, 4 (33.3% had polymenorrhagia. Out of 7 women with hyperthyroidism, 2 (28.57% had oligomenorrhoea, 3 (42.8% had heavy menstrual bleeding, 2 (28.57% had polymenorrhagia. In a total of 55 patients with AUB, 11 (20% had structural abnormalities in uterus and ovaries. 5 (9% had adenomyosis, 3 (5.4% had ovarian cysts, 3 (5.4% had fibroids. Conclusions: It is important to screen all women for thyroid abnormality who are presenting with AUB especially with non-structural causes of AUB. Correction of thyroid abnormalities also relieves AUB. This will avoid unnecessary hormonal treatment and surgery. [Int J Res Med Sci 2015; 3(11.000: 3250-3253

  8. Management of abnormal radioactive wastes at nuclear power plants

    International Nuclear Information System (INIS)

    As with any other industrial activity, a certain level of risk is associated with the operation of nuclear power plants and other nuclear facilities. That is, on occasions nuclear power plants or nuclear facilities may operate under conditions which were not specifically anticipated during the design and construction of the plant. These abnormal conditions and situations may cause the production of abnormal waste, which can differ in character or quantity from waste produced during normal routine operation of nuclear facilities. Abnormal waste can also occur during decontamination programmes, replacement of a reactor component, de-sludging of storage ponds, etc. The management of such kinds of waste involves the need to evaluate existing waste management systems in order to determine how abnormal wastes should best be handled and processed. There are no known publications on this subject, and the IAEA believes that the development and exchange of such information among its Member States would be useful for specialists working in the waste management area. The main objective of this report is to review existing waste management practices which can be applied to abnormal waste and provide assistance in the selection of appropriate technologies and processes that can be used when abnormal situations occur. Naturally, the subject of abnormal waste is complex and this report can only be considered as a guide for the management of abnormal waste. Refs, figs and tabs.

  10. A composite score combining procalcitonin, C-reactive protein and temperature has a high positive predictive value for the diagnosis of intensive care-acquired infections

    Science.gov (United States)

    2013-01-01

    Background Nosocomial infection diagnosis in the intensive care unit (ICU) remains a challenge. We compared routine measurements of procalcitonin (PCT), C-reactive protein (CRP), white blood cell count (WBC) and temperature in the detection of ICU-acquired infections. Method Prospective observational cohort study in a University hospital Medicosurgical ICU. All patients admitted to the ICU ≥ 5 days (n = 141) were included into two groups, either infected (documented infection, n = 25) or non-infected (discharged from the ICU without diagnosis of infection, n = 88). Results PCT, CRP, WBC and temperature progression from day −4 (D-4) to day 0 (D0) (day of infection diagnosis or ICU discharge) was analysed. Differences (Δ) were calculated as D0 levels minus the lowest preceding value. D0 PCT and CRP were significantly increased in infected compared to non-infected patients (median, 1st and 3rd quartiles): 3.6 ng/mL (0.92-25) for PCT, 173 mg/L (126–188) for CRP versus 0.02 ng/mL (0.1-0.9) and 57 mg/mL (31–105) respectively (p  38.6°C, PCT > 1.86 ng/mL, and CRP > 88 mg/L, performed well (AUCs of 0.88, 0.84, and 0.88 respectively). The sensitivity/specificity profiles of each marker (76%/94% for temperature, 68%/91% for PCT, and 92%/70% for CRP) led to a composite score (0.068 × D0 PCT + 0.005 × D0 CRP + 0.7 × temperature) more highly specific than each component (AUC of 0.90 and sensitivity/specificity of 80%/97%). Conclusion Combining CRP, PCT and temperature is an approach which may increase of nosocomial infection detection in the ICU. PMID:23547830

    Serum procalcitonin (ProCT) is elevated in response to bacterial infections, whereas high sensitivity C-reactive protein (hsCRP) is a nonspecific inflammatory marker that is increased by excess adipose tissue. We examined the efficacy of ProCT and hsCRP as biomarkers of periodontitis in the saliva and serum of patients with arthritis, which is characterized by variable levels of systemic inflammation that potentially can confound the interpretation of inflammatory biomarkers. Blood and unstimulated whole saliva were collected from 33 patients with rheumatoid arthritis (RA) and 50 with osteoarthritis (OA). Periodontal status was assessed by full mouth examination and patients were categorized as having no/mild, moderate or severe periodontitis by standard parameters. Salivary and serum ProCT and hsCRP concentrations were compared. BMI, diabetes, anti-inflammatory medications and smoking status were ascertained from the patient records. Differences between OA and RA in proportionate numbers of patients were compared for race, gender, diabetes, adiposity and smoking status. Serum ProCT was significantly higher in arthritis patients with moderate to severe and severe periodontitis compared with no/mild periodontitis patients. There were no significant differences in salivary ProCT or salivary or serum hsCRP in RA patients related to periodontitis category. Most of the OA and RA patients were middle aged or older, 28.9% were diabetic, 78.3% were overweight or obese, and slightly more than half were either current or past smokers. The OA and RA groups differed by race, but not gender; blacks and males were predominant in both groups. The OA and RA groups did not differ in terms of controlled or uncontrolled diabetes, smoking status or BMI. The RA patients had been prescribed more anti-inflammatory medication than the OA patients. Our results demonstrate that circulating ProCT is a more discriminative biomarker for periodontitis than serum hsCRP in patients with

    The purpose of the study was to develop a mathematical model for determining knee loads for abnormal gait. Abnormal gait was defined as a person with varus, i.e. “bowleggedness”, or a person who had an external rotation of the femur (or the inability to internally rotate the femur) which caused an indirect varus in the forward positions of gait. Conditions such as these have been observed clinically to result in increased wear on the medial condyle of total knee replacements. This problem was...

    Full Text Available Abstract Background Short stature is associated with several disorders including wide variations of chromosomal disorders and single gene disorders. The objective of this report is to present the cytogenetic findings in Indonesian patients with short stature. Methods G-banding and interphase/metaphase FISH were performed on short stature patients with and without other clinical features who were referred by clinicians all over Indonesia to our laboratory during the year 2003–2009. Results The results of chromosomal analysis of ninety seven patients (mean age: 10.7 years old were collected. The group of patients with other clinical features showed sex chromosome abnormalities in 45% (18/40 and autosomal abnormalities in 10% (4/40, whereas those with short stature only, 42.1% (24/57 had sex chromosome abnormalities and 1.75% (1/57 had autosomal abnormalities. The autosomal chromosomal abnormalities involved mostly subtelomeric regions. Results discrepancies between karyotype and FISH were found in 10 patients, including detection of low-level monosomy X mosaicism in 6 patients with normal karyotype, and detection of mosaic aneuploidy chromosome 18 in 1 patient with 45,XX,rob(13;14(q10;q10. Statistical analysis showed no significant association between the groups and the type of chromosomal abnormalities. Conclusion Chromosome abnormalities account for about 50% of the short stature patients. Wide variations of both sex and autosomal chromosomes abnormalities were detected in the study. Since three out of five patients had autosomal structural abnormalities involving the subtelomeric regions, thus in the future, subtelomeric FISH or even a more sensitive method such as genomic/SNP microarray is needed to confirm deletions of subtelomeric regions of chromosome 9, 11 and 18. Low-level mosaicism in normal karyotype patients indicates interphase FISH need to be routinely carried out in short stature patients as an adjunct to karyotyping.

    This study was undertaken to determine the teratogenic potential of methylmercury on chick embryogenesis. Methylmercuric chloride was dissolved in sodium bicarbonate (0.2%) and administered to the chick embryos at doses ranging from 0.0009 to 0.010 mg per egg. The injections were made at days 2 and 3 on incubation (Groups A and B). All the embryos including controls were examined on the 7th day of incubation. Methylmercury poisoning was observed to be both embryolethal and teratogenic. Within the two groups, embryolethality was higher in Group A. The following congenital abnormalities were observed: exencephaly, shortened and twisted limbs, microphthalmia, shortened and twisted neck, beak abnormalities, everted viscera, reduced body size and hemorrhage all over the body. Exencephaly and limb abnormalities were very common. No differences in the incidence and types of gross abnormalities within both the groups (A and B) were noted. The incidence of malformations among the controls was low. The results of present investigation show that methylmercury poisoning is both embryolethal and teratogenic to early chick embryogenesis.

    Anna Christina Rast

    2015-01-01

    Full Text Available The Glasgow Prognostic Score (GPS is useful for predicting long-term mortality in cancer patients. Our aim was to validate the GPS in ED patients with different cancer-related urgency and investigate whether biomarkers would improve its accuracy. We followed consecutive medical patients presenting with a cancer-related medical urgency to a tertiary care hospital in Switzerland. Upon admission, we measured procalcitonin (PCT, white blood cell count, urea, 25-hydroxyvitamin D, corrected calcium, C-reactive protein, and albumin and calculated the GPS. Of 341 included patients (median age 68 years, 61% males, 81 (23.8% died within 30 days after admission. The GPS showed moderate prognostic accuracy (AUC 0.67 for mortality. Among the different biomarkers, PCT provided the highest prognostic accuracy (odds ratio 1.6 (95% confidence interval 1.3 to 1.9, P<0.001, AUC 0.69 and significantly improved the GPS to a combined AUC of 0.74 (P=0.007. Considering all investigated biomarkers, the AUC increased to 0.76 (P<0.001. The GPS performance was significantly improved by the addition of PCT and other biomarkers for risk stratification in ED cancer patients. The benefit of early risk stratification by the GPS in combination with biomarkers from different pathways should be investigated in further interventional trials.

    Massaro, Karin SR; Costa, Silvia F; Leone, Claudio; Chamone, Dalton AF

    2007-01-01

    Background Procalcitonin (PCT) is an inflammatory marker that has been used as indicator of severe bacterial infection. We evaluated the concentrations of PCT as a marker for systemic infection compared to C-reactive protein (CRP) in patients neutropenic febrile. Methods 52 adult patients were enrolled in the study. Blood sample was collected in order to determine the serum concentrations of PCT, CRP and other hematological parameters at the onset of fever. The patients were divided into 2 groups, one with severe infection (n = 26) and the other in which the patients did not present such an infection (n = 26). Then PCT and CRP concentrations at the fever onset were compared between groups using non parametric statistical tests, ROC curve, sensitivity, specificity, likelihood ratio, and Spearman's correlation coefficient. Results The mean of PCT was significantly higher in the group with severe infection (6.7 ng/mL versus 0.6 ng/mL – p = 0.0075) comparing with CRP. Serum concentrations of 0.245 ng/mL of PCT displayed 100% de sensitivity and 69.2% specificity. PCT concentrations of 2,145 ng/mL presented a likelihood ratio of 13, which was not observed for any concentration of CRP. Conclusion PCT seems to be an useful marker for the diagnosis of systemic infection in febrile neutropenic patients, probably better than CRP. PMID:18034890

    2016-06-01

    Procalcitonin (PCT) has been used to guide treatment in critically ill patients with sepsis, but whether PCT at intensive care unit (ICU) discharge can stratify risks of post-ICU readmission or mortality is unknown. This cohort study compared the ability of PCT with C-reactive protein (CRP) in predicting unexpected adverse post-ICU events. Of the 1877 patients admitted to the multidisciplinary ICU between 1 April 2012 and 31 March 2014, 1653 (88.1%) were discharged without treatment limitations. A total of 71 (4.3%) were readmitted and 18 patients (1%) died unexpectedly after ICU discharge during the same hospitalization. Both PCT (0.6 vs 0.4 μg/L, P = .002) and a high CRP concentration >100 mg/L (58% vs 41%, P = .004) at ICU discharge were associated with an increased risk of adverse post-ICU events in the univariate analyses; however, the ability of PCT to discriminate between patients with and without adverse post-ICU outcomes was limited (area under the receiver operating characteristic curve = 0.61; 95% confidence interval, 0.55-0.66). In the multivariable analysis, only a high CRP concentration (odds ratio, 1.92; 95% confidence interval, 1.12-3.11; P = .008) was associated with an increased adverse post-ICU events. Elevated PCT concentration at ICU discharge was inadequate in its predictive ability to guide ICU discharge. PMID:27020769

    Full Text Available Abstract Background Procalcitonin (PCT is a polypeptide with several cationic aminoacids in its chemical structure and it is a well known marker of sepsis. It is now emerging that PCT might exhibit some anti-inflammatory effects. The present study, based on the evaluation of the in vitro interaction between PCT and bacterial lipopolisaccharide (LPS, reports new data supporting the interesting and potentially useful anti-inflammatory activity of PCT. Results PCT significantly decreased (p Salmonella typhimurium (rough chemotype and Escherichia coli (smooth chemotype. Subsequently, the in vitro effects of PCT on LPS-induced cytokine release were studied in human peripheral blood mononuclear cells (PBMC. When LPS was pre-incubated for 30 minutes with different concentrations of PCT, the release of interleukin-10 (IL-10 and tumor necrosis factor alpha (TNFα by PBMC decreased in a concentration-dependent manner after 24 hours for IL-10 and 4 hours for TNFα. The release of monocyte chemotactic protein-1 (MCP-1 exhibited a drastic reduction at 4 hours for all the PCT concentrations assessed, whereas such decrease was concentration-dependent after 24 hours. Conclusions This study provides the first evidence of the capability of PCT to directly neutralize bacterial LPS, thus leading to a reduction of its major inflammatory mediators.

  1. Procalcitonin NH2-terminal cleavage peptide has no mitogenic effect on normal human osteoblast-like cells

    International Nuclear Information System (INIS)

    The NH2-terminal cleavage peptide of procalcitonin (N-proCT) recently was reported to be a bone cell mitogen. The authors have investigated the effect of N-proCT on the proliferation of normal human cells that have the phenotype of mature osteoblasts (hOB cells). N-proCT treatment for 24, 48, or 96 h in concentrations from 1 nM to 1 microM did not significantly increase [3H]thymidine uptake (means ranged from -19% to 38% of control, no significant differences) in hOB cells (6-10 cell strains per experiment) plated at four different densities. However, the hOB cells responded significantly to treatment with transforming growth factor β (3 ng/ml), bovine insulin (300 micrograms/ml), or 30% fetal calf serum, which were included in all experiments as positive controls. The [3H]thymidine uptake data were confirmed in a direct cell count experiment tested at 96 h. Thus they data do not support the hypothesis that N-proCT is a potent mitogen for normal human osteoblasts

  2. Procalcitonin as a biomarker for severe Plasmodium falciparum disease: a critical appraisal of a semi-quantitative point-of-care test in a cohort of travellers with imported malaria

    2009-09-01

    Full Text Available Abstract Background Imported malaria occurs as a relatively rare event in developed countries. As a consequence, most clinicians have little experience in making clinical assessments of disease severity and decisions regarding the need for parenteral therapy or high-level monitoring. In this study, the diagnostic accuracy of procalcitonin (PCT for severe Plasmodium falciparum disease was assessed in a cohort of 100 consecutive travellers with various species of imported malaria. Methods and results In all patients, PCT was measured on admission with a semi-quantitative 'point-of-care' test. Patients with severe P. falciparum malaria had significantly higher median PCT levels on admission as compared with patients with uncomplicated P. falciparum disease. In addition, PCT levels in patients with non-falciparum malaria were also higher compared with patients with non-severe falciparum malaria but lower compared with severe P. falciparum malaria. At a cut-off point of 10 ng/mL, PCT had a sensitivity of 0,67 and a specificity of 0,94 for severe falciparum disease. However, at lower cut-off points the specificity and positive predictive value were rather poor although the sensitivity and negative predictive value remained high. Discussion Potential drawbacks in the interpretation of elevated PCT levels on admission may be caused by infections with non-falciparum species and by concomitant bacterial infections. Conclusion Semi-quantitative determination of PCT on admission is of limited use in the initial clinical assessment of disease severity in travellers with imported malaria, especially in settings with limited experience with the treatment of malaria.

    Functional facial deformities are usually described as those that impair respiration, eating, hearing, or speech. Yet facial scars and cutaneous deformities have a significant negative effect on social functionality that has been poorly documented in the scientific literature. Insurance companies are declining payments for reconstructive surgical procedures for facial deformities caused by congenital disabilities and after cancer or trauma operations that do not affect mechanical facial activity. The purpose of this study was to establish a large, sample-based evaluation of the perceived social functioning, interpersonal characteristics, and employability indices for a range of facial appearances (normal and abnormal). Adult volunteer evaluators (n = 210) provided their subjective perceptions based on facial physical appearance, and an analysis of the consequences of facial deformity on parameters of preferential treatment was performed. A two-group comparative research design rated the differences among 10 examples of digitally altered facial photographs of actual patients among various age and ethnic groups with "normal" and "abnormal" congenital deformities or posttrauma scars. Photographs of adult patients with observable congenital and posttraumatic deformities (abnormal) were digitally retouched to eliminate the stigmatic defects (normal). The normal and abnormal photographs of identical patients were evaluated by the large sample study group on nine parameters of social functioning, such as honesty, employability, attractiveness, and effectiveness, using a visual analogue rating scale. Patients with abnormal facial characteristics were rated as significantly less honest (p = 0.007), less employable (p = 0.001), less trustworthy (p = 0.01), less optimistic (p = 0.001), less effective (p = 0.02), less capable (p = 0.002), less intelligent (p = 0.03), less popular (p = 0.001), and less attractive (p = 0.001) than were the same patients with normal facial

  6. Manganese Abnormity in Holocene Sediments of the Bohai Sea

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Manganese abnormity has been observed in the Holocene sediments of the mud area of Bohai Sea. On the basis of grain size, chemical composition, heavy mineral content and accelerator mass spectrometry (AMS) 14C dating of foraminifer, relationships between manganese abnormity and sedimentation rates, material source, hydrodynamic conditions are probed. Manganese abnormity occurred during the Middle Holocene when sea level and sedimentation rates were higher than those at present. Sedimentary hiatus was not observed when material sources and hydrodynamic conditions were quite similar. Compared with the former period, the latter period showed a decrease in reduction environment and an inclination toward oxidation environment with high manganese content, whereas provenance and hydrodynamic conditions showed only a slight change. From the above observations, it can be concluded that correlation among manganese abnormity, material source, and hydrodynamic conditions is not obvious. Redox environment seems to be the key factor for manganese enrichment, which is mainly related to marine authigenic process.

    We present a new interpretation of dark energy in terms of an \\textit{Abnormally Weighting Energy} (AWE). This means that dark energy does not couple to gravitation in the same way as ordinary matter, yielding a violation of the weak and strong equivalence principles on cosmological scales. The resulting cosmological mechanism accounts for the Hubble diagram of type Ia supernovae in terms of both cosmic acceleration and variation of the gravitational constant while still accounting for the pr...

    Background This study was conducted to investigate whether point-of-care (POC) procalcitonin (PCT) measurement can reduce redundant antibiotic treatment in patients hospitalized with acute exacerbation of COPD (AECOPD). Methods One-hundred and twenty adult patients admitted with AECOPD were enrolled in this open-label randomized trial. Patients were allocated to either the POC PCT-guided intervention arm (n=62) or the control arm, in which antibiotic therapy followed local guidelines (n=58). Results The median duration of antibiotic exposure was 3.5 (interquartile range [IQR] 0–10) days in the PCT-arm vs 8.5 (IQR 1–11) days in the control arm (P=0.0169, Wilcoxon) for the intention-to-treat population. The proportion of patients using antibiotics for ≥5 days within the 28-day follow-up was 41.9% (PCT-arm) vs 67.2% (P=0.006, Fisher’s exact) in the intention-to-treat population. For the per-protocol population, the proportions were 21.1% (PCT-arm) vs 73.9% (P<0.00001, Fisher’s exact). Within 28-day follow-up, one patient died in the PCT-arm and two died in the control arm. A composite harm end point consisting of death, rehospitalization, or intensive care unit admission, all within 28 days, showed no apparent difference. Conclusion Our study shows that the implementation of a POC PCT-guided algorithm can be used to substantially reduce antibiotic exposure in patients hospitalized with AECOPD, with no apparent harm.

    Febrile neutropenia (FN) requires immediate use of antibiotics (ATB), and procalcitonin (PCT) is proven to be useful in guiding antibiotic therapy in different settings. This study investigated the use of PCT as a guide for the duration of ATB in FN. A randomized controlled trial was carried out from January-December 2010. A total of 62 hematological adult patients with FN were randomized, in 1:1 ratio, into two groups: (1) PCT group: length of ATB guided by institutional protocol plus PCT dynamics, and (2) control group: duration of ATB in accordance with institutional protocol. There was no difference between groups regarding the use of ATB for the first episode of fever (HR 1.14, 95 % CI 0.66-1.95, p = 0.641), with equivalent median duration of ATB therapy (PCT group 9.0 days and control group 8.0 days, p = 0.67), and median number of days without ATB (0 days, IQR 0-2 days for both groups, p = 0.96). We observed no difference in clinical cure rate (p = 0.68), infection relapse (p = 1.0), superinfection (p = 0.85), length of hospitalization (p = 0.64), and mortality at 28 days (p = 0.39) and at 90 days (p = 0.72). Considering the cut-off of 0.5 ng/ml, PCT was correlated with bacteremia (sensitivity of 51.9 % and specificity of 76.5 %). In this randomized controlled trial, adding a PCT-guided protocol to the standard recommendations did not reduce the use of antibiotics in febrile neutropenia, although no apparent harm was caused. PCT proved to be a marker of bacteremia in this setting. PMID:27118539

    2014-01-01

    Full Text Available Even though the phenomenon of abnormal grain coarsening (AGC or “exploded grains” has been known to occur in Alloy 718 industrial forgings there is still no satisfactory explanation for it. For this reason, detailed microstructure analysis has been carried out in normal and abnormal regions. Electron Backscatter Diffraction (EBSD was employed to determine grain size, boundary distribution and measure stored energy, while backscattered imagining in a FEGSEM was used to measure δ precipitate size and morphology. It was found that abnormal regions show almost 3 times as many twin boundaries compared to a normal region. In addition, the δ phase morphologies differ very significantly when comparing these two different regions. Normal regions display δ phase with a plate like nature, whereas in abnormal regions, δ particles appear to be more spherical. Furthermore, there are clear indications of differences in δ volume fractions between the two regions. Whilst in normal regions the δ phase is found predominantly at grain boundaries, in abnormal regions the δ is also found within grains. Both backscatter images and EBSD scans indicate that there are higher levels of stored energy within the normal regions, compared to the abnormal regions. These observations suggest that AGC occurs in regions where dynamic recrystallization does not happen and where recrystallization during solution heat treatment is affected by the local particle distribution.

    Chromosomal abnormalities are among the most common genetic causes of spermatogenic disruptions. Carriers of chromosomal abnormalities are at increased risk of infertility, miscarriage or birth of a child with unbalanced karyotype due to the production of unbalanced gametes. The natural selection against chromosomally abnormal sperm usually prevents fertilization with sperm barring in cases of serious chromosomal abnormalities.

    Deviations in the growth of the mandibular condyle can affect both the functional occlusion and the aesthetic appearance of the face. The reasons for these growth deviations are numerous and often entail complex sequences of malfunction at the cellular level. The aim of this review is to summarize recent progress in the understanding of pathological alterations occurring during childhood and adolescence that affect the temporomandibular joint (TMJ) and, hence, result in disorders of mandibular growth. Pathological conditions taken into account are subdivided into (1) congenital malformations with associated growth disorders, (2) primary growth disorders, and (3) acquired diseases or trauma with associated growth disorders. Among the congenital malformations, hemifacial microsomia (HFM) appears to be the principal syndrome entailing severe growth disturbances, whereas growth abnormalities occurring in conjunction with other craniofacial dysplasias seem far less prominent than could be anticipated based on their often disfiguring nature. Hemimandibular hyperplasia and elongation undoubtedly constitute the most obscure conditions that are associated with prominent, often unilateral, abnormalities of condylar, and mandibular growth. Finally, disturbances of mandibular growth as a result of juvenile idiopathic arthritis (JIA) and condylar fractures seem to be direct consequences of inflammatory and/or mechanical damage to the condylar cartilage.

  6. Ventilation abnormalities in pulmonary embolus

    International Nuclear Information System (INIS)

    The ventilation scans of 11 patients with angiographically-proven PE were reviewed. All patients had one or more lung perfusion defects. The chest roentgenograph was abnormal in 11 of the patients. The ventilation studies were performed in the posterior positron prior to the perfusion lung scan using Xe-133. The ventilation study consists of washin, equilibrium, and washout images. In four patients with normal washin there was retention of the Xe-133 (delayed washout) at the site of the perfusion defect. All had roentgenographic abnormalities. Another pattern was observed at the sites of some perfusion defects in six patients. In these, there was decreased washin at the perfusion defect location. Two patients had both decreased washin and delayed washout. In only one case was the typical ventilation pattern of normal washin and normal washout. The method of retention is unclear, but may be due to decreased clearance of Xe-133 secondary to decreased blood flow in the area or deposition of some fat soluble component left at the site of embolization. The etiology of the reduced washin is unclear, but may be due to reduced surfactant production. This study suggests that more attention must be paid to the ventilation study, where there may be additional clues to the diagnosis of pulmonary embolus

    Full Text Available Abstract The finding, during the last decade, that several common, clinically delineated syndromes are caused by submicroscopic deletions or, more rarely, by duplications, has provided a powerful tool in the annotation of the human genome. Since most microdeletion/microduplication syndromes are defined by a common deleted/duplicated region, abnormal dosage of genes located within these regions can explain the phenotypic similarities among individuals with a specific syndrome. As such, they provide a unique resource towards the genetic dissection of complex phenotypes such as congenital heart defects, mental and growth retardation and abnormal behaviour. In addition, the study of phenotypic differences in individuals with the same microdeletion syndrome may also become a treasury for the identification of modifying factors for complex phenotypes. The molecular analysis of these chromosomal anomalies has led to a growing understanding of their mechanisms of origin. Novel tools to uncover additional submicroscopic chromosomal anomalies at a higher resolution and higher speed, as well as the novel tools at hand for deciphering the modifying factors and epistatic interactors, are 'on the doorstep' and will, besides their obvious diagnostic role, play a pivotal role in the genetic dissection of complex phenotypes.

    Early and accurate differentiation between infectious and non-infectious fever is vitally important in the intensive care unit (ICU). In the present study, patients admitted to the medical ICU were screened daily from August 2008 to February 2009. Within 24 hr after the development of fever (>38.3℃), serum was collected for the measurement of the procalcitonin (PCT) and high mobility group B 1 levels. Simplified Acute Physiology Score (SAPS) II and Acute Physiology And Chronic Health Evaluation (APACHE) III scores were also analyzed. Sixty-three patients developed fever among 448 consecutive patients (14.1%). Fever was caused by either infectious (84.1%) or non-infectious processes (15.9%). Patients with fever due to infectious causes showed higher values of serum PCT (7.8±10.2 vs 0.5±0.2 ng/mL, P=0.026), SAPS II (12.0±3.8 vs 7.6±2.7, P=0.006), and APACHE III (48±20 vs 28.7±13.3, P=0.039) than those with non-infectious fever. In receiver operating characteristic curve analysis, the area under the curve was 0.726 (95% CI; 0.587-0.865) for PCT, 0.759 (95% CI; 0.597-0.922) for SAPS II, and 0.715 (95% CI; 0.550-0.880) for APACHE III. Serum PCT, SAPS II, and APACHE III are useful in the differentiation between infectious and non-infectious fever in the ICU.

    Full Text Available Chromosomal abnormalities are involved in the etiology of recurrent spontaneous pregnancy loss and sub-fertility. The purpose of this study was to determine the frequency and contribution of chromosomal abnormalities in recurrent miscarriages. The results obtained and literature review are helpful in understanding the importance of cytogenetics analysis of female infertility. To investigate the distribution of chromosomal abnormalities in the Romanian population with recurrent miscarriage, karyotype analysis by G-banding was performed from peripheral blood in 967 women infertility. Results: Chromosomal abnormalities were found to 79 women (8,17%. The percentage of chromosomal abnormalities in the studied population correlates with the data in the literature. Chromosomal abnormalities could play the important role in etiology of infertility and are more frequently detected in this group of patients compared to general population. In the infertile couples balanced chromosomal abnormalities are the main cause of spontaneous abortions.

    Full Text Available We test the hypothesis that strategies which are long on portfolios of looser stocks and short on portfolios of winner stocks generate abnormal returns in Brazil. This type of evidence for the US stock market was interpreted by The Bondt and Thaler (1985 as reflecting systematic evaluation mistakes caused by investors overreaction to news related to the firm performance. We found evidence of contrarian strategies profitability for horizons from 3 months to 3 years in a sample of stock returns from BOVESPA and SOMA from 1986 to 2000. The strategies are more profitable for shorter horizons. Therefore, there was no trace of the momentum effect found by Jagadeesh and Titman (1993 for the same horizons with US data. There are remaing unexplained positive returns for contrarian strategies after accounting for risk, size, and liquidity. We also found that the strategy profitability is reduced after the Real Plan, which suggests that the Brazilian stock market became more efficient after inflation stabilization.

    Health monitoring systems require a means for detecting and quantifying abnormalities from measured signals. In this paper, a new method for detecting abnormalities in a human gait is proposed for an improved gait monitoring system for patients with walking problems. In the previous work, we introduced a fuzzy logic algorithm for detecting phases in a human gait based on four foot pressure sensors for each of the right and left foot. The fuzzy logic algorithm detects the gait phases smoothly and continuously, and retains all information obtained from sensors. In this paper, a higher level algorithm for detecting abnormalities in the gait phases obtained from the fuzzy logic is discussed. In the proposed algorithm, two major abnormalities are detected 1) when the sensors measure improper foot pressure patterns, and 2) when the human does not follow a natural sequence of gait phases. For mathematical realization of the algorithm, the gait phases are dealt with by a vector analysis method. The proposed detection algorithm is verified by experiments on abnormal gaits as well as normal gaits. The experiment makes use of the Smart Shoes that embeds four bladders filled with air, the pressure changes in which are detected by pressure transducers.

    Marfan syndrome (MFS), a multisystem autosomal-dominant disorder, is characterized by mutations of the fibrillin-1 (FBN1) gene and by abnormal patterns of synthesis, secretion, and matrix deposition of the fibrillin protein. To determine the sensitivity and specificity of fibrillin protein abnormalities in the diagnosis of MFS, we studied dermal fibroblasts from 57 patients with classical MFS, 15 with equivocal MFS, 8 with single-organ manifestations, and 16 with other connective tissue disorders including homocystinuria and Ehlers-Danlos syndrome. Abnormal fibrillin metabolism was identified in 70 samples that were classified into four different groups based on quantitation of fibrillin synthesis and matrix deposition. Significant correlations were found for phenotypic features including arachnodactyly, striae distensae, cardiovascular manifestations, and fibrillin groups II and IV, which included 70% of the MFS patients. In addition, these two groups were associated with shortened {open_quotes}event-free{close_quotes} survival and more severe cardiovascular complications than groups I and III. The latter included most of the equivocal MFS/single manifestation patients with fibrillin abnormalities. Our results indicate that fibrillin defects at the protein level per se are not specific for MFS, but that the drastically reduced fibrillin deposition, caused by a dominant-negative effect of abnormal fibrillin molecules in individuals defined as groups II and IV, is of prognostic and possibly diagnostic significance. 25 refs., 3 figs., 6 tabs.

  18. Lithium treatment and thyroid abnormalities

    2006-09-01

    autoimmunity do not much differ from those observed in the general population; h hyperthyroidism and thyroid cancer are observed rarely during lithium treatment. Recommendations Thyroid function tests (TSH, free thyroid hormones, specific antibodies, and ultrasonic scanning should be performed prior to starting lithium prophylaxis. A similar panel should be repeated at one year. Thereafter, annual measurements of TSH may be sufficient to prevent overt hypothyroidism. In the presence of raised TSH or thyroid autoimmunity, shorter intervals between assessments are advisable (4–6 months. Measurement of antibodies and ultrasonic scanning may be repeated at 2-to-3-year intervals. The patient must be referred to the endocrinologist if TSH concentrations are repeatedly abnormal, and/or goitre or nodules are detected. Thyroid function abnormalities should not constitute an outright contraindication to lithium treatment, and lithium should not be stopped if a patient develops thyroid abnormalities. Decisions should be made taking into account the evidence that lithium treatment is perhaps the only efficient means of reducing the excessive mortality which is otherwise associated with affective disorders.

  19. Screening for fetal chromosome abnormalities during the second trimester

    International Nuclear Information System (INIS)

    Objective: To develop a pre -natal screening program for fetal chromosome abnormalities based on risk values calculated from maternal serum markers levels during the second trimester. Methods: Serum levels of AFP, β-HCG, uE3 were determined with CLIA in 1048 pregnant women during 14-21w gestation period and the results were analyzed with a specific software (screening program for Down' s syndrome developed by Beckman) for the risk rate. In those women defined as being of high risk rate, cells from amniotic fluid or umbilical cord blood were studied for karyotype analysis. Results: Of these 1048 women, 77 were designated as being of high risk rate for several chromosome abnormalities i.e. Down's syndrome, open spina bifida and trisomy -18 syndrome (overall positive rate 7.3%). Further fetal chromosome study in 31 of them revealed three proven cases of abnormality. Another cord blood study was performed in a calculated low risk rate case but with abnormal sonographic finding at 31 w gestation and proved to be abnormal (software study false negative). The remaining 46 high risk rate cases either refused future study (n=35) or were lost for follow-up (n=11). Fortunately, all the 35 women refused further study gave birth to normal babies without any chromosome abnormalities discovered on peripheral blood study. Besides, in a trial study, five high risk rate women were again evaluated a few weeks later but with tremendous difference between the results. Conclusion: The present program proves to be clinically useful but needs further study and revision. Many factors may influence the result of the analysis and the duration of gestation period in weeks should be as accurate as possible. At present, in order to avoid getting false negatives, we don't advise a second check in 'high risk' cases. (authors)

    We will study the epidemiologic, clinical, biological, therapeutic, prognostic characteristics and predictive factors of development of nephropathy in ankylosing spondylitis patients. We retrospectively reviewed the medical record of 32 cases with renal involvement among 212 cases of ankylosing spondylitis followed in our service during the period spread out between 1978 and 2006. The renal involvement occurred in all patients a mean of 12 years after the clinical onset of the rheumatic disease. Thirty-two patients presented one or more signs of renal involvement: microscopic hematuria in 22 patients, proteinuria in 23 patients, nephrotic syndrome in 11 patients and decreased renal function in 24 patients (75%). Secondary renal amyloidosis (13 patients), which corresponds to a prevalence of 6,1% and tubulointerstitial nephropathy (7 patients) were the most common cause of renal involvement in ankylosing spondylitis followed by IgA nephropathy (4 patients). Seventeen patients evolved to the end stage renal disease after an average time of 29.8 ± 46 months. The average follow-up of the patients was 4,4 years. By comparing the 32 patients presenting a SPA and renal disease to 88 with SPA and without nephropathy, we detected the predictive factors of occurred of nephropathy: tobacco, intense inflammatory syndrome, sacroileite stage 3 or 4 and presence of column bamboo. The finding of 75% of the patients presented a renal failure at the time of the diagnosis of renal involvement suggests that evidence of renal abnormality involvement should be actively sought in this disease.

    2011-07-01

    Full Text Available Introduction: Taste and smell abnormalities have proven to be an extremely more complex subject than previously regarded. Wide-ranging nosologic entities arise along with smell and taste alterations, and they can be congenital or acquired. Objective: Analyze the main features of smell and taste dysfunctions. Method: Automated databases were used to collect data, by searching keywords like 'alteration', 'smell', and 'taste'. A non-systematic search was also made in scientific printings and medical books. Literature Review: Smell and taste dysfunctions have a vast etiology, the most significant of which are obstructive nasal and sinusal disease, infections of the upper respiratory tract, cranioencephalic trauma, aging, exposure to toxics and some drugs, nasal or intracranial neoplasias, psychiatric and neurological pathologies, iatrogenic disease, idiopathic and congenital causes. A detailed anamnesis, a careful physical examination and supplementary evaluations are important for the diagnosis of these alterations. Conclusion: As a rule, smell and taste dysfunctions occur in a combined way. The early discovery of such dysfunctions can lead to a more efficient treatment, making the progress of diseases causing them retard and the symptoms less severe. In many cases, treating these alterations is not easy and there needs to be a multidisciplinary cooperation among the otorhinolaryngologist, endocrinologist, neurologist, psychiatrist, among others.

Le pronostic des pathologies aiguës chez le sujet âgé est difficile à évaluer car il est à la fois lié à la pathologie aiguë et à d'autres facteurs tels que le statut fonctionnel ou les pathologies chroniques associées. Peu de biomarqueurs ont été étudiés dans ce cadre. L'objectif de cette étude était d'évaluer l'intérêt de la procalcito...

    The assumption that consumers prefer cosmetically perfect fruits and vegetables contributes to global food waste, because food retailers refuse to offer abnormally shaped food. This study empirically examines how food shape abnormality affects purchase intentions and how two individual difference...... variables, environmental concern and social trust, might moderate the food shape abnormality–purchase intention relationship for consumers in China. A representative sample of 212 Chinese consumers indicated their purchase intentions for two fruits and two vegetables with varying levels of food shape...... abnormality (normal, moderately abnormal, and extremely abnormal). The results demonstrate that food shape influences purchase intentions; consumers are more likely to purchase normally shaped fruits and vegetables than moderately or extremely abnormally shaped food. However, environmental concern and social...

    Background Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. Objective We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. Methods This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. Results Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (p<0.001). Conclusions Nail abnormalities were more prevalent in vitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study. PMID:27579738

    Full Text Available Adjustment of composition of body fluids and electrolytes is one of the most important aspects of patients care. Sodium and Potassium are the most important body cations, the improper adjustment of them will cause sever disorders in neuromuscular, gastrointestinal, respiratory and cardiovascular systems. Acute renal failure indicated by increase in creatinine and nitrogen urea, brings an accumulation of fluids, salts and metabolites of nitrogen in body. This study intends to assess the status of electrolyte abnormalities and mortality rates of the patients hospitalized in ICU wards in our country. This is a descriptive and retrospective study on the records of 378 patients hospitalized in ICU. A questionnaire was prepared and the data were entered in SPSS system. They were statistically analyzed by using chi-square and fisher's Exact test methods. Out of 378 patients hospitalized in ICU, over 2/3 of them were male and over half of them were>45 years old. Frequency distribution of electrolyte abnormalities was as follows: Hyponatremia 59% hypernatremia 23% hypokalemia 37% hyperkalemia 28%, 35% and 21% of patients had respectively BUN and creatinine more than the normal range. 26% of patients hospitalized in ICU had nonsurgical problems and 74% of the patients had surgical problems. Average time of hospitalization in ICU was 85 days and mortality rate was 35%. The most common electrolyte abnormality was related to variation in serum sodium levels in the form of hyponatremia. And the highest prevalence electrolyte abnormality in dead patients was hyponatremia. This study proves that the prevalence of electrolyte abnormalities is directly related to mortality and increase in hospitalization period and those having undergone surgical operations during hospitalization in ICU, manifested more abnormalities.

    2016-08-20

    Burn causes bone metabolic abnormality in most cases, including the changes in osteoblasts and osteoclasts, bone mass loss, and bone absorption, which results in decreased bone mineral density. These changes are sustainable for many years after burn and even cause growth retardation in burned children. The mechanisms of bone metabolic abnormality after burn include the increasing glucocorticoids due to stress response, a variety of cytokines and inflammatory medium due to inflammatory response, vitamin D deficiency, hypoparathyroidism, and bone loss due to long-term lying in bed. This article reviews the pathogenesis and regularity of bone metabolic abnormality after burn, the relationship between bone metabolic abnormality and burn area/depth, and the treatment of bone metabolic abnormality, etc. and discusses the research directions in the future.

    Full Text Available Chromosomal abnormalities are among the most common genetic causes of spermatogenic disruptions. Carriers of chromosomal abnormalities are at increased risk of infertility, miscarriage or birth of a child with unbalanced karyotype due to the production of unbalanced gametes. The natural selection against chromosomally abnormal sperm usually prevents fertilization with sperm barring in cases of serious chromosomal abnormalities. However, assisted reproductive technologies in general and intracytoplasmic sperm injection in particular, enable the transmission of chromosomal abnormalities to the progeny. Therefore, cytogenetic studies are important in patients with male factor infertility before assisted reproduction treatment. The purpose of the current study was to investigate the types and frequencies of chromosomal abnormalities in 724 patients with infertility and to estimate the risk of chromosomal abnormalities detection in subgroups of patients depending on the severity of spermatogenic disruption, aiming at identifying groups of patients in need of cytogenetic studies. Karyotype analysis was performed in 724 blood samples of men attending infertility clinic. Chromosomal preparation was performed by standard techniques. At least 20 GTG-banded metaphase plates with the resolution from 450 to 750 bands per haploid set were analysed in each case. When chromosomal mosaicism was suspected, this number was increased to 50. Abnormal karyotypes were observed in 48 (6.6% patients, including 67% of autosomal abnormalities and 33% of gonosomal abnormalities. Autosomal abnormalities were represented by structural rearrangements. Reciprocal translocations were the most common type of structural chromosomal abnormalities in the studied group, detected with the frequency of 2.6% (n = 19, followed by Robertsonian translocation, observed with the frequency of 1.2% (n = 9. The frequency of inversions was 0.6% (n = 4. Gonosomal abnormalities included 14 cases

    Abnormalities in cortical structure are commonly observed in children with dyslexia in key regions of the "reading network." Whether alteration in cortical features reflects pathology inherent to dyslexia or environmental influence (e.g., impoverished reading experience) remains unclear. To address this question, we compared MRI-derived metrics of cortical thickness (CT), surface area (SA), gray matter volume (GMV), and their lateralization across three different groups of children with a historical diagnosis of dyslexia, who varied in current reading level. We compared three dyslexia subgroups with: (1) persistent reading and spelling impairment; (2) remediated reading impairment (normal reading scores), and (3) remediated reading and spelling impairments (normal reading and spelling scores); and a control group of (4) typically developing children. All groups were matched for age, gender, handedness, and IQ. We hypothesized that the dyslexia group would show cortical abnormalities in regions of the reading network relative to controls, irrespective of remediation status. Such a finding would support that cortical abnormalities are inherent to dyslexia and are not a consequence of abnormal reading experience. Results revealed increased CT of the left fusiform gyrus in the dyslexia group relative to controls. Similarly, the dyslexia group showed CT increase of the right superior temporal gyrus, extending into the planum temporale, which resulted in a rightward CT asymmetry on lateralization indices. There were no group differences in SA, GMV, or their lateralization. These findings held true regardless of remediation status. Each reading level group showed the same "double hit" of atypically increased left fusiform CT and rightward superior temporal CT asymmetry. Thus, findings provide evidence that a developmental history of dyslexia is associated with CT abnormalities, independent of remediation status.

    2007-07-01

    The optical parameters of tissue-equivalent phantoms are determined by matching the normalized backscattering intensity (NBI) profiles iteratively with that obtained by Monte Carlo simulation procedure. Tissue equivalent optical phantoms (control and with abnormality) were prepared by mixing measured quantities of paraffin wax with wax colors. Abnormalities to be placed in the phantoms were prepared by controlling the absorption and scattering coefficients. The NBI profiles of the phantoms are obtained by an automatic non-contact scanning multi-probe laser reflectometer and are displayed as gray level images after processing. The NBI variations from the abnormality phantoms have distinct variations based on the optical characteristics of the abnormality embedded at various locations and depths. There is a considerable decrease or increase in the NBI variations for different detector probes based on the increase or decrease in absorption and scattering coefficients of abnormalities, respectively. From the profile of subtracted image the peak corresponds to the location of the abnormality and from the full width at half maximum the size of the abnormality is obtained. By further scanning of the image of the phantom with abnormality the depth of the embedded abnormality is obtained.

    Elevated frequencies of abnormal embryos in female eelpout Zoarces viviparus have been demonstrated in Danish, Swedish and German monitoring programmes at certain geographic locations with high levels of anthropogenic input. Pollutants present in areas with high malformation frequencies were selected and tested in a controlled laboratory experiment for their potential to induce abnormalities among eelpout embryos upon injection into pregnant eelpout. Tributyltin, 2,3,7,8-tetrachlorodibenzo-p-dioxin, pyrene, nonylphenol, 2,2',4,4'-tetrabromophenylether and heptadecafluorooctanesulfonic acid were tested, either individually or combined. Generally, the chemicals were transferred to eggs and/or embryos. Some of the exposures increased the proportion of broods with more than 10% abnormal or 5% malformed embryos, although the average percentages of abnormal development were not affected. Spinal, cranial and eye deformities were evident, similarly to what is seen in nature. Some of the exposures resulted in increased percentages of females with as well a low reproductive capacity as embryos with a low condition index.

    Overcrowding is one of the most crucial issues confronting emergency departments (EDs) throughout the world. Efficient management of patient flows for ED services has become an urgent issue for most hospital administrations. Handling and detection of abnormal situations is a key challenge in EDs. Thus, the early detection of abnormal patient arrivals at EDs plays an important role from the point of view of improving management of the inspected EDs. It allows the EDs mangers to prepare for high levels of care activities, to optimize the internal resources and to predict enough hospitalization capacity in downstream care services. This study reports the development of statistical method for enhancing detection of abnormal daily patient arrivals at the ED, which able to provide early alert mechanisms in the event of abnormal situations. The autoregressive moving average (ARMA)-based exponentially weighted moving average (EWMA) anomaly detection scheme proposed was successfully applied to the practical data collected from the database of the pediatric emergency department (PED) at Lille regional hospital center, France.

    Full Text Available Background: The Chromagen lens system comprises of tinted spectacle or contact lenses, each with a specific colour wavelength filter which controls the spectra of the light entering the eye. This study investigated whether spectacle-mounted Chromagen lenses would enhance colour perception in individuals with abnormal colour vision.Methods: The Ishihara colour test was used to test for colour vision deficiency (CVD and also to evaluate the effect of the Chromagen spectacle lens on colour perception in 13 subjects. An Oculus Anomaloscope was used to confirm and sub-classify the types of CVD. Subjects comprised of school age children from the Riyadh area in Saudi Arabia.Results: The distribution amongst the male participants comprised two subjects with protanomaly, two with protanopia, five with deuteranomaly, and two with deuteranopia. Amongst the two female participants, one subject showed deuteranomaly, and one showed protanomaly. Different types of Chromagen spectacle lenses displayed some levels of colour vision enhancement depending on type of CVD.Conclusion: The findings support the notion that chromagen lenses could enhance colour vision perception in some cases of red-green colour vision defects. Clients with CVD should be managed on an individual case basis. (S Afr Optom 2011 70(2 69-74

    Angiotensin-(1-7) [Ang-(1-7)] may have beneficial effects in diabetes mellitus-induced erectile dysfunction (DMIED) but its molecular actions in the diabetic corpus cavernosum (CC) are not known. We characterized the effects of diabetes and/or chronic in vivo administration of Ang-(1-7) on vascular reactivity in the rat corpus cavernosum (CC) and on protein expression levels of potential downstream effectors of the renin-angiotensin-aldosterone system (RAAS) such as angiotensin-converting enzyme (ACE), ACE2, Rho kinases 1 and 2 (ROCK1 and ROCK2), and omega-hydroxylase, the cytochrome-P450 enzyme that metabolizes arachidonic acid to form the vasoconstrictor, 20-hydroxyeicosatetraenoic acid. Streptozotocin-treated rats were chronicically administered Ang-(1-7) with or without A779, a Mas receptor antagonist, during weeks 4 to 6 of diabetes. Ang-(1-7) reversed diabetes-induced abnormal reactivity to vasoactive agents (endothelin-1, phenylepherine, and carbachol) in the CC without correcting hyperglycemia. Six weeks of diabetes led to elevated ACE, ROCK1, ROCK 2, and omega-hydroxylase and a concomitant decrease in ACE2 protein expression levels that were normalized by Ang-(1-7) treatment but not upon coadministration of A779. These data are supportive of the notion that the beneficial effects of Ang-(1-7) in DMIED involve counterregulation of diabetes-induced changes in ACE, ACE2, Rho kinases, and omega-hydroxylase proteins in the diabetic CC via a Mas receptor-dependent mechanism.

    Bowel rotation abnormalities in heterotaxy are common. As more children survive cardiac surgery, the management of gastrointestinal abnormalities has become controversial. To evaluate imaging of malrotation in heterotaxy with surgical correlation and provide an algorithm for management. Imaging reports of heterotaxic children with upper gastrointestinal (UGI) and/or small bowel follow-through (SBFT) were reviewed. Subsequently, fluoroscopic images were re-reviewed in conjunction with CT/MR studies. The original reports and re-reviewed images were compared and correlated with surgical findings. Nineteen of 34 children with heterotaxy underwent UGI, 13/19 also had SBFT. In 15/19 reports, bowel rotation was called abnormal: 11 malrotation, 4 non-rotation, no cases of volvulus. Re-review, including CT (10/19) and MR (2/19), designated 17/19 (90%) as abnormal, 10 malrotation (abnormal bowel arrangement, narrow or uncertain length of mesentery) and 7 non-rotation (small bowel and colon on opposite sides plus low cecum with probable broad mesentery). The most useful CT/MR findings were absence of retroperitoneal duodenum in most abnormal cases and location of bowel, especially cecum. Abnormal orientation of mesenteric vessels suggested malrotation but was not universal. Nine children had elective bowel surgery; non-rotation was found in 4/9 and malrotation was found in 5/9, with discrepancies (non-rotation at surgery, malrotation on imaging) with 4 original interpretations and 1 re-review. We recommend routine, early UGI and SBFT studies once other, urgent clinical concerns have been stabilized, with elective laparoscopic surgery in abnormal or equivocal cases. Cross-sectional imaging, usually obtained for other reasons, can contribute diagnostically. Attempting to assess mesenteric width is important in differentiating non-rotation from malrotation and more accurately identifies appropriate surgical candidates. (orig.)

    Intraoperative manometry of the biliary tract and measurement of amylase levels in choledochal cysts were performed in seven patients, aged 14 months to 5 years, with choledochal cysts, in an investigation of the pathophysiology of the biliary tract. An abnormal choledochopancreatico ductal junction was observed in these seven patients by preoperative endoscopic retrograde cholangiopancreaticography (ERCP) or intraoperative cholangiograms. All six patients examined showed a high amylase level in the choledochal cyst (5,450 to 46,500 Somogyi Units). The intraoperative manometry of the biliary tract showed that a remarkable high pressure zone as was found in the area of sphincter of Oddi was not found in the area of abnormal choledochopancreatico ductal junction. The pressure recordings also demonstrated that the sphincter of Oddi pressure in the patient with choledochal cyst was increased by gastrin stimulation. On the contrary, no pressure reaction to gastrin or secretin was found in the area of abnormal choledochopancreatic ductal junction. From these results it seems that free reflux of pancreatic juice into the biliary system occurs, and the reflux stream depends upon the pressure gradient between pancreatic ductal pressure and common bile duct pressure because of the lack of a sphincter function at the choledochopancreatico ductal junction.

  13. Fetal calcifications are associated with chromosomal abnormalities.

    Directory of Open Access Journals (Sweden)

    Ellika Sahlin

    Full Text Available The biological importance of calcifications occasionally noted in fetal tissues (mainly liver at autopsy or ultrasound is largely unexplored. Previous reports hint at an association to infection, circulatory compromise, malformations or chromosomal abnormalities. To identify factors associated with calcifications, we have performed a case-control study on the largest cohort of fetuses with calcifications described thus far.One-hundred and fifty-one fetuses with calcifications and 302 matched controls were selected from the archives of the Department of Pathology, Karolinska University Hospital. Chromosome analysis by karyotyping or quantitative fluorescence-polymerase chain reaction was performed. Autopsy and placenta reports were scrutinized for presence of malformations and signs of infection.Calcifications were mainly located in the liver, but also in heart, bowel, and other tissues. Fetuses with calcifications showed a significantly higher proportion of chromosomal abnormalities than controls; 50% vs. 20% (p<0.001. The most frequent aberrations among cases included trisomy 21 (33%, trisomy 18 (22%, and monosomy X (18%. A similar distribution was seen among controls. When comparing cases and controls with chromosomal abnormalities, the cases had a significantly higher prevalence of malformations (95% vs. 77%, p=0.004. Analyzed the other way around, cases with malformations had a significantly higher proportion of chromosomal abnormalities compared with controls, (66% vs. 31%, p<0.001.The presence of fetal calcifications is associated with high risk of chromosomal abnormality in combination with malformations. Identification of a calcification together with a malformation at autopsy more than doubles the probability of detecting a chromosomal abnormality, compared with identification of a malformation only. We propose that identification of a fetal tissue calcification at autopsy, and potentially also at ultrasound examination, should infer

  14. Sweating in Systemic Abnormalities: Uremia and Diabetes Mellitus.

    Murota, Hiroyuki

    2016-01-01

    Sweating disorders are sometimes observed in various systemic diseases that include genetic disorders, organ damage, metabolic impairment, autoimmune diseases, and neuropathic disorders. In these diseases, various symptoms such as autonomic failures, psychopathic disorders, abnormal skin innervation, and sweat gland dysfunction can interact with one another in diverse ways, resulting in impaired sweating. This review focuses on the influence of uremia (with or without hemodialysis) and diabetes mellitus on impaired sweating. Dialysis patients perspire less, but their sweat contains higher levels of uremic toxins than do healthy subjects. Neuropathic disorders in diabetes patients develop in relation to disease severity and can impair sweating. Physicians should consider the development of various problems, such as increased body temperature, dry skin, and increased susceptibility to infection, due to decreased sweating, as they are often found in these systemic abnormalities.

  15. ADEPT - Abnormal Doppler Enteral Prescription Trial

    Directory of Open Access Journals (Sweden)

    McCormick Kenny

    2009-10-01

    Full Text Available Abstract Background Pregnancies complicated by abnormal umbilical artery Doppler blood flow patterns often result in the baby being born both preterm and growth-restricted. These babies are at high risk of milk intolerance and necrotising enterocolitis, as well as post-natal growth failure, and there is no clinical consensus about how best to feed them. Policies of both early milk feeding and late milk feeding are widely used. This randomised controlled trial aims to determine whether a policy of early initiation of milk feeds is beneficial compared with late initiation. Optimising neonatal feeding for this group of babies may have long-term health implications and if either of these policies is shown to be beneficial it can be immediately adopted into clinical practice. Methods and Design Babies with gestational age below 35 weeks, and with birth weight below 10th centile for gestational age, will be randomly allocated to an "early" or "late" enteral feeding regimen, commencing milk feeds on day 2 and day 6 after birth, respectively. Feeds will be gradually increased over 9-13 days (depending on gestational age using a schedule derived from those used in hospitals in the Eastern and South Western Regions of England, based on surveys of feeding practice. Primary outcome measures are time to establish full enteral feeding and necrotising enterocolitis; secondary outcomes include sepsis and growth. The target sample size is 400 babies. This sample size is large enough to detect a clinically meaningful difference of 3 days in time to establish full enteral feeds between the two feeding policies, with 90% power and a 5% 2-sided significance level. Initial recruitment period was 24 months, subsequently extended to 38 months. Discussion There is limited evidence from randomised controlled trials on which to base decisions regarding feeding policy in high risk preterm infants. This multicentre trial will help to guide clinical practice and may also

Blood drug levels were monitored throughout the study. Before treatment with tall gastrodis tuber, 35 of the 100 cases had abnormal CT/MRI scans; 79 cases had abnormal single photon emission computed tomography images; 86 cases had abnormal electroencephalogram; and a total of 146 abnormal perfusion foci were observed across the 100 subjects. After treatment, the number of patients with normal single photon emission computed tomography images increased by 12; normal electroencephalogram was observed in an additional 27 cases and the number of patients with epileptiform discharge decreased by 29 (34% of 86); the total number of abnormal perfusion foci decreased by 52 (36%) and changes in abnormal foci were visible in 65 patients. These changes indicate that the administration of tall gastrodis tuber in combination with antiepileptic drugs repairs abnormal perfusion foci in patients with focal epilepsy. Our results demonstrate that traditional Chinese drugs can repair abnormal perfusion foci and, as such, are a promising new pathway in the treatment of focal epilepsy.

    Objective To investigate the prevalence of abnormity of blood lipid and associated factors in healthy population in Beijing.Methods Totally,38462 individuals who received health examination were enrolled in our study.We divided them into eight groups according to their ages.The levels of serum total cholesterol,triglyceride,high density lipoprotein cholesterol,and low density lipoprotein cholesterol were tested,and the relationship of blood lipid abnormity with body mass index(BMI)and fasting blood glucose was analyzed.Results The incidences of hypercholesterolemia,hyperglyceridemia,low high-density lipoprotein cholesterolemia,and hyper low-density lipoprotein cholesterolemia presented increasing trend in this population.The incidence rate of abnormity of blood lipid in health examination population increased with BMI increase.The incidence of abnormity of blood lipid in overweight and obesity population was significantly higher than that in low weight and normal weight populations(P<0.05).Meanwhile,the trend of abnormal blood lipid incidence coincided with that of abnormal fasting blood glucose.Conclusions The prevalence of overweight,obesity,and abnormity of blood lipid in Beijing presents increasing trend.The incidence of abnormity of blood lipid increases with BMI increase,in coincidence with that of fasting blood glucose.

    Full Text Available Electrophysiological and behavioral studies in primary dystonia suggest abnormalities during movement preparation, but this crucial phase preceding movement onset has not yet been studied specifically with functional magnetic resonance imaging (fMRI. To identify abnormalities in brain activation during movement preparation, we used event-related fMRI to analyze behaviorally unimpaired sequential finger movements in 18 patients with task-specific focal hand dystonia (FHD and 18 healthy subjects. Patients and controls executed self-initiated or externally cued prelearnt four-digit sequential movements using either right or left hands. In FHD patients, motor performance of the sequential finger task was not associated with task-related dystonic posturing and their activation levels during motor execution were highly comparable with controls. On the other hand reduced activation was observed during movement preparation in the FHD patients in left premotor cortex / precentral gyrus for all conditions, and for self-initiation additionally in supplementary motor area, left mid-insula and anterior putamen, independent of effector side. Findings argue for abnormalities of early stages of motor control in FHD, manifesting during movement preparation. Since deficits map to regions involved in the coding of motor programs, we propose that task-specific dystonia is characterized by abnormalities during recruitment of motor programs: these do not manifest at the behavioral level during simple automated movements, however, errors in motor programs of complex movements established by extensive practice (a core feature of FHD, trigger the inappropriate movement patterns observed in task-specific dystonia.
