Inflammatory markers in patients after hematopoietic stem cell transplantation.
    Archivum immunologiae et therapiae experimentalis, 2013, Volume: 61, Issue:4

    Infections are one of the most common complications after hematopoietic stem cell transplantation (HSCT). Diagnosis is established by analysis of clinical symptoms and results of diagnostic tests such as biochemical panels, microbiological cultures, and visual diagnostics. As the microbiological cultures yield positive results in only some patients and visual diagnostics might miss the infectious source, the diagnosis and proper treatment often depends on clinical assessment supported by laboratory test results. The most commonly used makers of inflammation include C-reactive protein and procalcitonin. However, these tests have serious limitations when used in patients after HSCT. The drugs used in conditioning, neutropenia, and graft-versus-host disease might influence the results of the tests and misguide the physician. In this review, we summarize the current knowledge on profiles of expression of basic markers of inflammation used in clinical practice in patients after HSCT.

Comparison of the diagnostic value of procalcitonin and C-reactive protein after hematopoietic stem cell transplantation: a systematic review and meta-analysis.
    Transplant infectious disease : an official journal of the Transplantation Society, 2013, Volume: 15, Issue:3

    To conduct a systematic review and meta-analysis of the performance of the procalcitonin (PCT) diagnostic test for identifying infectious complications after hematopoietic stem cell transplantation (HSCT).. We searched EMBASE, MEDLINE, the Cochrane database, and reference lists of relevant articles, with no language restrictions, through December 2011. We selected original articles that reported diagnostic performance of PCT alone or compared with other biomarkers for identifying serious infections in HSCT recipients. We quantitatively evaluated test accuracy parameters with the use of forest plots, hierarchical summary receiver operating characteristic curves, and bivariate random effect models.. We found 6 qualifying studies (studying 1344 episodes of suspected infection with confirmed infectious episodes) from 3 countries. These 6 studies examined both PCT and C-reactive protein (CRP) test performance. Bivariate pooled sensitivity, specificity, positive likelihood ratios, and negative likelihood ratios were 0.66 (95% confidence interval [CI] 0.60-0.72), 0.72 (95% CI 0.65-0.79), 2.39 (95% CI 1.84- 3.09), and 0.47 (95% CI 0.39-0.57) for PCT, and 0.80 (95% CI 0.54-0.93), 0.73 (95% CI 0.56-0.86), 3.00 (95% CI 1.86-4.84), and 0.27 (95% CI 0.11-0.65) for CRP. In terms of area under the curve (AUC), CRP was superior to PCT in detecting infectious complications, with an AUC of 0.82 for CRP versus an AUC of 0.69 for PCT.. The pooled accuracy estimates of 6 different studies indicated only a moderate rule-out diagnostic value of both PCT and CRP in discriminating infection from other inflammatory complications following allogeneic HSCT.

[Neonatal infections. Diagnostic markers of infection].
    Akusherstvo i ginekologiia, 2010, Volume: 49, Issue:5

    Infections are highly prevalent in the neonatal period. Unfortunately the symptoms of infection are non-specific and are seen in other neonatal diseases as: respiratory distress syndrome, metabolic diseases, intracranial hemorrhages. Diagnosis is based on the clinics, microbiologic tests and laboratory markers of infection. Considering the high mortality and serious morbidity associated with neonatal sepsis, a diagnostic marker with a very high sensitivity and negative predictive value approaching 100% is desirable. Unfortunately there is no laboratory marker that has all of the characteristics of ideal infection marker. Procalcitonin, interleukins 6 and 8, CD 11b are early, sensitive markers of infection. C- reactive protein is a late specific marker of infection. CD 64 is the most sensitive marker of late, nosocomial infection. Serial measurement of infection markers will certainly improve the diagnostic sensitivity of these tests, because in most circumstances it is not certain at which stage of the infection the specimen should be taken for analysis. In addition, the use of multiple markers, in particular, combining an early sensitive marker with a late specific test will further enhance the diagnostic accuracy of these mediators in identifying infected cases.

A Retrospective Analysis of Drug Fever Diagnosed during Infectious Disease Consultation.
    Internal medicine (Tokyo, Japan), 2016, Volume: 55, Issue:6

    To clarify the current situation concerning drug fever (DF) in Japan, we retrospectively analyzed patients undergoing infectious disease consultation at our institution.. Between April 2014 and May 2015, we extracted the records of DF patients from among 388 patients who had obtained infectious disease consultations in Kurume University Hospital. We reviewed their medical charts and summarized the characteristics of DF.. This study included the records of 16 patients. Clinical signs (relative bradycardia, the duration of the drug administration before becoming febrile, and the interval between the discontinuation of a drug and the alleviation of a fever), and laboratory tests (varied white blood cell count, low level of C-reactive protein, and a mild elevation of transaminases) were compatible with those from previous reports. Among the drug-confirmed cases, five involved the use of glycopeptides (vancomycin: 3, teicoplanin: 2), which were considered to be uncommon causes, and the another five cases involved the use of β-lactams. In addition, the procalcitonin levels were either negative or low (≤0.25 ng/mL) in 10 of the 11 procalcitonin-measured cases.. Our findings demonstrated that glycopeptides, similar to β-lactams, may be the origin of DF. Furthermore, procalcitonin may be helpful in the diagnosis of DF, but only in combination with other detailed examinations.

Diagnostic accuracy of C-reactive protein and procalcitonin in the early detection of infection after elective colorectal surgery - a pilot study.
    BMC infectious diseases, 2014, Aug-16, Volume: 14

    Colorectal surgery is associated with postoperative infectious complications in up to 40% of cases, but the diagnosis of these complications is frequently misleading, delaying its resolution. Several biomarkers have been shown to be useful in infection diagnosis.. We conducted a single-centre, prospective, observational study segregating patients submitted to elective colorectal surgery with primary anastomosis, CRP and PCT were measured daily. We compared infected and non-infected patients.. From October 2009 to June 2011, a total of 50 patients were included. Twenty-one patients developed infection. PCT and CRP before surgery were equally low in patients with or without postoperative infectious complications. After surgery, both PCT and CRP increased markedly. CRP time-course from the day of surgery onwards was significantly different in infected and non-infected patients (P = 0.001) whereas, PCT time-course was almost parallel in both groups (P = 0.866). Multiple comparisons between infected and non-infected patients from 5th to 9th postoperative days (POD) were performed and CRP concentration was significantly different (P < 0.01, Bonferroni correction), on the 6th, 7th and 8th POD. A CRP concentration > 5.0 mg/dl at the D6 was predictive of infection with a sensitivity of 85% and a specificity of 62% (positive likelihood ratio 2.2, negative likelihood ratio 0.2).. After a major elective surgical insult both CRP and PCT serum levels increased independently of the presence of infection. Besides serum CRP time-course showed to be useful in the early detection of an infectious complication whereas PCT was unhelpful.

Procalcitonin variations after Emergency Department admission are highly predictive of hospital mortality in patients with acute infectious diseases.
    European review for medical and pharmacological sciences, 2013, Volume: 17 Suppl 1

    To evaluate the diagnostic and prognostic usefulness of procalcitonin (PCT) in patients admitted to the Emergency Department (ED) with signs of infections and to assess the prognostic value of repeated measurements in predicting hospital mortality.. A prospective, observational study was conducted in our 400-bed General Teaching Hospital. 261 patients arriving in ED with signs/symptoms of infection were enrolled. PCT was performed upon arrival in the ED (T0), and 5 days after antibiotic therapy (T5). Blood cultures were performed in all patients upon arrival in the ED.. Mean T0 PCT value was 7.1±17.9 ng/ml, and at T5 3±9.1 ng/ml (p < 0.0001). Mean PCT in septic non-survivors was increased at T5 compared to T0 but not significantly. The PCT increase at T5 was an independent factor of mortality (OR = 1.29, p < 0.02) in septic patients. Compared to baseline mean delta % PCT decrease at T5 was 28%. Patients with a decrease delta % PCT > 28% showed a lower number of deaths, with a statistical significant difference if compared to those patients with a < 28% decrease (p < 0.004). ROC curve of delta % PCT for prediction of death has an AUC = 0.82 (p < 0.03).. PCT is a useful marker for diagnosis of systemic and local infections, and for prognostic stratification in patients with acute infectious diseases at their arrival in ED. PCT variations after antibiotic therapy are highly predictive for in-hospital mortality. PCT normalization during antibiotic therapy suggests a good response to infection possibly leading to less infection-related deaths.

Opinion paper on innovative approach of biomarkers for infectious diseases and sepsis management in the emergency department.
    Clinical chemistry and laboratory medicine, 2013, Volume: 51, Issue:6

    Sepsis is a leading healthcare problem, accounting for the vast majority of fatal events in critically ill patients. Beyond early diagnosis and appropriate treatment, this condition requires a multifaceted approach for monitoring the severity, the potential organ failure as well as the risk of death. Monitoring of the efficacy of treatment is also a major issue in the emergency department (ED). The assessment of critically ill conditions and the prognosis of patients with sepsis is currently based on some scoring systems, which are, however, inefficient to provide definite clues about organ failure and prognosis in general. The discretionary and appropriate use of some selected biomarkers such as procalcitonin, inducible protein 10 (IP10), Group IV phospholipase A2 type II (PLA2 II), neutrophil gelatinase-associated lipocalin (NGAL), natriuretic peptides, mature adrenomedullin (ADM), mid-regional pro-adrenomedullin (MR-proADM), copeptin, thrombopoietin, Mer receptor and even red blood cell distribution width (RDW) represent thereby an appealing perspective in the diagnosis and management of patients with sepsis. Nevertheless, at the moment, it is not still clear if it is better to use a multimarkers approach or if a single, most appropriate, biomarker exists. This collective opinion paper is aimed at providing an overview about the potential clinical usefulness of some innovative biomarkers of sepsis in its diagnosis and prognosis, but also in the treatment management of the disease. This manuscript represents a synopsis of the lectures of Third Italian GREAT Network Congress, that was hold in Rome, 15-19 October 2012.

The value of serum procalcitonin in differential diagnosis of pulmonary embolism and community-acquired pneumonia.
    Clinical and applied thrombosis/hemostasis : official journal of the International Academy of Clinical and Applied Thrombosis/Hemostasis, 2011, Volume: 17, Issue:5

    Presence of high fever may cause confusion in differential diagnosis of pulmonary embolism (PE) versus pneumonia. The aim of this study is to investigate the diagnostic value of serum procalcitonin (PCT) in differential diagnosis of PE and community-acquired pneumonia (CAP). A total of 24 patients with proven PE and 22 patients with CAP were included in the study. The study population was subdivided as PE patients with fever (group 1, n = 8) and without fever (group 2, n = 16); and CAP (group 3, n = 22). Serum PCT and systemic inflammatory markers were measured at the initial diagnosis and the third day of the treatment. The relation of PCT level with the other systemic inflammatory markers was investigated in each measurement point. The initial mean serum PCT level in group 3 (2.24 ± 0.99 ng/mL) was statistically higher than group 1 (0.48 ± 0.77 ng/mL) and group 2 (0.14 ± 0.17 ng/mL; P = .000, .000, respectively). Procalcitonin level at the initial (2.24 ± 0.99 ng/mL) and the third day of treatment (0.92 ± 0.62 ng/mL) in group 3 showed a statistically significant reduction (P = .000). There were no statistically significant reduction in PCT levels by anticoagulation in groups 1 and 2 (P = .262, .119, respectively). Other systemic inflammatory markers including interleukin 6 (IL-6), C-reactive protein (CRP), and tumor necrosis factor α (TNF-α) levels statistically significantly decreased with anticoagulant and antimicrobial therapy. This study suggested that serum PCT level may be valuable for differentiating PE patients with or without fever from patients with CAP.

The value of procalcitonin and the SAPS II and APACHE III scores in the differentiation of infectious and non-infectious fever in the ICU: a prospective, cohort study.
    Journal of Korean medical science, 2010, Volume: 25, Issue:11

    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.

Procalcitonin as marker of infection in patients with Goodpasture's syndrome is misleading.
    Nephrology, dialysis, transplantation : official publication of the European Dialysis and Transplant Association - European Renal Association, 2007, Volume: 22, Issue:9

    Procalcitonin (PCT) is routinely measured to differentiate autoimmune disorders from infection. There are reports, however, where PCT is high in the absence of infection, i.e. in vasculitis. To investigate the value of PCT in Goodpasture's syndrome, we reviewed the charts of patients with Goodpasture's syndrome who were treated from 1996 to 2006.. PCT (normal range<0.5 ng/ml) was measured with an immunoluminometric assay, C-reactive protein (CRP; normal range<5 mg/l) with nephelometry. Anti-glomerular basement membrane antibodies (normal range<1:10) were measured with ELISA.. During the last 10 years we diagnosed seven patients with Goodpasture's syndrome. Six out of seven patients had biopsy proven crescentic and necrotizing glomerulonephritis. Five patients had a severe manifestation with pulmonary involvement (n=3) and/or severe renal insufficiency (n=4). Mean CRP levels were 145.7 mg/l, mean PCT levels were 34.1 ng/ml. Therapy consisted of plasmapheresis (n=3), pulse cyclophosphamide therapy (n=4) and glucocorticoids (n=6). Remarkably, all patients with elevated PCT levels had life-threatening disease (n=4) and remained dialysis-dependent (as compared to with only one out of three patients with normal PCT). In two out of five patients with severe Goodpasture's syndrome, PCT levels remained high. After thorough exclusion of infection, resumption of high dose glucocorticoids normalized PCT and CRP levels.. The measurement of PCT as a marker of infection in patients with Goodpasture's syndrome is misleading. High PCT values might rather point to a severe form of Goodpasture's syndrome with a more unfavourable prognosis. However, further studies with larger patient numbers are needed to prove this hypothesis.

Usefulness of procalcitonin as a marker of systemic infection in emergency department patients: a prospective study.
    Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2002, Apr-01, Volume: 34, Issue:7

    We prospectively evaluated serum procalcitonin concentrations in patients who presented to an emergency department (ED) with suspected infectious or inflammatory disease. Of 195 study patients, 68 had final diagnosis of systemic infection, and 24 of those 68 had elevated serum procalcitonin levels (>0.5 ng/mL). The procalcitonin level had a sensitivity of 0.35 and specificity of 0.99 for the diagnosis of systemic infection. In multivariate analysis, the procalcitonin level was the only independent variable associated with this diagnosis; in contrast, the C-reactive protein level was not. All patients with systemic infections who ultimately died had procalcitonin levels of >0.5 ng/mL at admission. Procalcitonin levels were significantly higher in patients who ultimately died of systemic infection than in patients who survived. The optimal procalcitonin threshold for the ED population may be lower than that proposed for critically ill patients. Determination of the procalcitonin level may be useful for screening and prognosis of more-severely ill ED patients.
