Abstract
Background CEA, CYFRA21-1 and NSE are tumor markers used for monitoring the response to chemotherapy in advanced adenocarcinoma, squamous cell carcinoma and small-cell lung cancer, respectively. Their role in cancer immunotherapy needs to be elucidated. Methods Patients with advanced non-small cell lung cancer (NSCLC) were treated with nivolumab 3 mg/kg every 2 weeks within the Italian Nivolumab Expanded Access Program. Blood samples were collected at baseline, at each cycle up to cycle 5 and then every two cycles until patient’s withdrawn from the study. All patients underwent a CT-scan after every 4 cycles of treatment and responses were classified according to RECIST 1.1. The biomarkers serum levels were measured with a chemiluminescent microparticle immunoassay for CEA and with an immuno radiometric assay for CYFRA21-1 and NSE. The markers values at baseline and after 4 cycles were used to analyze the relationship between their variation over baseline and the tumor response, evaluated as disease control rate (DCR: CR + PR + SD), and survival (PFS and OS). Results A total of 70 patients were evaluable for the analysis. Overall, a disease control was obtained in 24 patients (35.8%, 4 PR + 20 SD). After 4 cycles of nivolumab a CEA or CYFRA21-1 reduction ≥ 20% over the baseline was significantly associated with DCR (CEA, p = 0.021; CYFRA21-1, p < 0.001), PFS (CEA, p = 0.028; CYFRA21-1, p < 0.001) and OS (CEA, p = 0.026; CYFRA21-1, p = 0.019). Multivariate analysis confirmed the ability of CYFRA21-1 reduction ≥ 20% to predict DCR (p = 0.002) and PFS (p < 0.001). Conclusion The reduction in serum level of CYFRA21-1 or CEA might be a reliable biomarker to predict immunotherapy efficacy in NSCLC patients. NSE was not significant for monitoring the efficacy of nivolumab.

Abstract
PURPOSE The aim of this study was to judge the reliability of evaluating thyroid-stimulating hormone (TSH) and free thyroxine (f-T4) in the morning and afternoon in differentiated thyroid carcinoma (DTC) patients. METHODS We evaluated 153 DTC patients, aged 61 ± 13 years, in active follow-up in our center after primary treatments and under stabilized levo-thyroxine (L-T4) posology. In each patient, morning and afternoon examinations were performed 1-3 months apart. Blood samples were collected at 08:00-09:00 h and 15:00-16:00 h. TSH and f-T4 were evaluated in both samples. Thyroglobulin (Tg), Tg-antibodies and neck ultrasonography were also evaluated. RESULTS According to clinical and laboratory examinations, 92% of patients were disease-free, 6% had biochemical disease, and 2% structural disease. L-T4 dosages (1.64 ± 0.38 µg/kg b.w.) proved the same on both occasions, despite slight changes in body weight or L-T4 posology in 15% of patients. Free-T4 values were significantly higher in the afternoon (21.5 ± 0.3 pmol/L) than in the morning (18.8 ± 0.4 pmol/L; P < 0.0001), whereas TSH values were statistically unchanged (morning 0.85 ± 0.25 mIU/L; afternoon 0.72 ± 0.20 mIU/L). There was a significant correlation (P < 0.0001) between the two TSH determinations in the same patients. CONCLUSIONS In DTC patients, follow-up examination consists of clinical and laboratory evaluations. The majority of patients have good disease control. Our study suggests that the adequacy of L-T4 therapy can be monitored equally well either in the morning or in the afternoon. Afternoon examinations can alleviate crowding in hospital ambulatories in the morning.

Abstract
Background. Prescriptive appropriateness is an actual claim in healthcare, and it also concerns in vitro tests used in the allergy work-up, such as the serum allergen-specific IgE (sIgE) assay. In the Liguria Region, two panels were defined (for inhaled and food allergens) including 12 allergens. Their composition changed over time. Objectives. The aims of the present retrospective study were: i) to evaluate the percentage of positive tests, and ii) to compare the findings of sIgE assay on the basis of the general practictioners' (GPs) or specialist' prescription, considering both the old panels and the new panels. Methods. This retrospective study considered a population of adult patients, which consisted of 2368 subjects (68% females; mean age 50 years; age range: 10-103 years). Serum sIgE were measured by ImmunoCap system. Results. The percentages of positive tests were very low for food allergens and low for inhaled ones (ranging between 5% to 35%). There was change of prevalent prescriptor with new panels. Conclusions. This study underlines the relevance of prescriptive appropriateness in the allergy work-up. The sIgE assay should be limited to those allergens that have a clinical relevance, based on clinical history.

Abstract
BACKGROUND Allergic rhinitis (AR) is characterized by an IgE-mediated reaction. Aging usually induces a progressive decline of immune system function. There is common belief that both allergic symptoms severity and serum IgE production decline during aging. OBJECTIVE This study aimed to evaluate the possible impact of age on: i) serum allergen-specific IgE levels in a large sample of subjects, and ii) AR symptom severity in a group of mono-allergic patients. METHODS Serum allergen-specific IgE to birch, Bet v 1, Parietaria, and Dermatophagoides pteronyssinus were measured by immunofluorometric assay (IFMA) in a sample of 8098 subjects. AR symptom severity was assessed by visual analogue scale (VAS) in a sub-group of 531 mono-allergic patients. RESULTS The analysis of variance showed that IgE to Bet v 1, birch, and Dermatophagoides pteronyssinus significantly decreased considering the age, whereas IgE to Parietaria did not significantly decline in respect of the age. Considering the global sample of mono-allergic patients, elderly subjects (over 65 years old) tended to have lower IgE levels, but had significantly lower VAS rating, and significantly less sensitizations than adult subjects (18-65 years old). In both adult and elderly patients VAS strongly correlated with IgE values. CONCLUSIONS Allergen-specific IgE levels tend to reduce with aging, but with differences between types of allergy. The IgE decrease is usually associated with reduced AR symptom severity. Elderly AR patients seem to have a different phenotype/endotype in comparison with adult AR ones, characterized by milder symptoms, lower IgE production, and less sensitizations. However, a close positive relationship between IgE values and VAS scores is shared by both adult and elderly AR patients, confirming the close link between allergy and symptoms that persists also in the elderly.

Abstract
BACKGROUND Birch allergy (BA) is a common pollinosis caused by the allergens Bet v 1, Bet v 2, and Bet v 4. Oral allergy syndrome (OAS) is frequently associated with BA. A gradient of sensitization to birch allergen across Europe has been reported. Therefore, this study aimed to investigate the birch sensitization profile, including OAS, across Italy. METHODS We performed a retrospective study of 854 patients (391 males, mean age 35.9 years, range 18-93 years): 196 patients were recruited in Genoa, 188 in northern Italy, 359 in central Italy, and 111 in southern Italy. Serum IgE to Bet v 1, Bet v 2, and Bet v 4 was assessed, and OAS was analyzed. RESULTS With respect to the geographical path Genoa-North-Center-South, the frequency of sensitization to Bet v 1 decreased significantly (P<.0001) from Genoa (95.41%) to southern Italy (58.56%). The frequency of sensitization to Bet v 2 increased significantly (P<.0001) from Genoa (6.12%) to southern Italy (52.25%). The frequency of Bet v 4 also increased significantly (P=.0002) from Genoa (6.12%) to southern Italy (14.41%). The distribution of patients with OAS differed significantly across the areas (P<.0001), the most marked difference ranging between 33.5% in Genoa and 76.9% in northern Italy. The frequency of birch allergens correlated with OAS in central Italy only. CONCLUSIONS The present study demonstrated a significant difference between sensitization to birch and its clinical expression across Italy.

Abstract
INTRODUCTION Vitamin D deficiency consequences may go beyond altered calcium homeostasis and musculoskeletal disease. Medical inpatients are often vitamin D-deficient, but little information is available about the relation of vitamin D status with extra-skeletal disorders in this population. METHODS We analysed the relationship between the concentrations of 25-hydroxyvitamin D [25(OH)D], the marker of vitamin D status, and the conditions most commonly causing admission in 115 consecutive medical inpatients. RESULTS Sixty-five subjects (56.5%) had severe vitamin D deficiency [25(OH)D < 8 ng/ml]. Age (β = -0.35, p = 0.01) and hepatic disease (β = -0.21, p = 0.02) were significant correlates of 25(OH)D levels. Compared with patients with ≥ 8 ng/ml 25(OH)D, those with < 8 ng/ml 25(OH)D had significantly higher parathyroid hormone (PTH) concentrations [123 (92.7-208.2) ng/l vs. 88 (68.5-129.5) ng/l, p < 0.001], were significantly more likely to have arterial hypertension (OR 2.76, 95% CI 1.16-6.58), heart failure (HF) (OR 2.49, 95% CI 1.14-5.47), cerebrovascular disease (OR 3.23, 95% CI 1.41-7.39), and infections (OR 2.44, 95% CI 1.02-5.87), and stayed in hospital significantly longer (10 days vs. 7.5 days, p = 0.01). Only the probability of having an infection remained significantly higher in cases with severe vitamin D deficiency after adjustment for age (OR 2.41, 95% CI 1.03-5.68) and persisted after further correcting for presence of hepatic disease and PTH values (OR 2.66, 95% CI 1.03-6.88). A significant association between PTH and HF (OR 2.32, 95% CI 1.05-5.09) and length of hospitalisation (β = 0.22, p = 0.04) emerged in the fully adjusted regression models. CONCLUSIONS Severe vitamin D deficiency is associated with commonly presenting extra-skeletal diseases in medical inpatients. With the exception of infections, this association is mainly driven by age. Additional studies are needed to determine whether vitamin D testing on admission may help stratifying specific categories of patients by clinical severity.

Abstract
The actual reference range of serum uric acid has been assessed according to its variations among healthy individuals. i.e. those without clinical evidence of gout. By this approach, serum uric acid values between 3.5 and 7.2 mg/dL in adult males and postmenopausal women and between 2.6 and 6.0 mg/dL in premenopausal women have been identified as normal in many countries. However, this definition of normal range of serum uric acid in the general population is inevitably influenced by what we consider as "normal", since the absence of gout flares does not necessarily imply the absence of uric acid-related damage. Indeed, a growing body of evidence indicates that silent deposition of monosodium urate crystals as a result of hyperuricaemia may occur and lead to early destructive skeletal changes. In addition, a growing body of evidences demonstrates that uric acid might play a pathophysiological role in many "cardio-nephro-metabolic" disorders, which seems to be independent of the deposition of monosodium urate crystals, since it is evident also for serum uric acid concentrations below the saturation point for monosodium urate. Taken together, these findings strongly suggest to carefully reconsider the concept of "asymptomaticity" for chronic hyperuricemia and to consequently revise the normal range of serum uric acid levels also considering the progressive worldwide increase of circulating levels of uric acid, which could lead to a "shift to right" (i.e. toward higher values) of normal range. In the light of the new scientific knowledge on the pathophysiological role of uric acid in human disease, a threshold value < 6.0 mg/dL (< 360 µmol/L) seems to better identify true "healthy subjects" and should reasonably be considered for all subjects.

Abstract
BACKGROUND Candida bloodstream infections (BSI) represent an important problem in Intensive Care Units (ICUs). The epidemiology of candidemia is changing with an increase in the proportion of Candida (C.) non-albicans. OBJECTIVES An Italian 2-year observational survey on ICU was conducted to evaluate the species distribution and possible differences between BSI caused by C. albicans and C. non-albicans. For comparative purposes, we performed a European literature-based review to evaluate distribution and frequency of Candida spp. causing ICU candidemia, during the period 2000-2013. MATERIALS AND METHODS This laboratory-based survey involved 15 microbiology centers (GISIA-3 study). All candidemia episodes in adult patients were considered. Data were prospectively collected from 2007 to 2008. PubMed was searched for peer-reviewed articles. RESULTS In total, 462 candidemia episodes were collected. C. albicans accounted for 49.4% of the isolates, followed by C. parapsilosis (26.2%) and C. glabrata (10.4%). Mortality was higher in patients with C. non-albicans than C. albicans (47.3% vs. 32.4 %, p > 0.05). Among risk factors, parenteral nutrition was more common (p = 0.02) in non-albicans candidemia, while surgery was more frequent (p = 0.02) in C. albicans candidemia. Twenty-four relevant articles were identified. C. albicans was the predominant species in almost all studies (range 37.9% -76.3%). C. glabrata was commonly isolated in the German-speaking countries, France, UK and North Europe; C. parapsilosis in Turkey, Greece and Spain. CONCLUSIONS Although C. non-albicans BSI is increasing, our study shows that C. albicans is still the predominant species in ICU candidemia. There are differences in the epidemiology of Candida BSI among European countries, with a prevalence of C. glabrata and C. parapsilosis in Northern and Southern countries, respectively.

Abstract
Although internal medicine wards (IMWs) represent a significant reservoir of patients with candidemia, few investigators have specifically addressed the epidemiological aspects of candidaemia in this population. Of all patients hospitalized during the study period with candidaemia, 133/348 (38%) were admitted to IMWs. Variables associated with IMWs included: antibiotic therapy prior to hospitalization, urinary or central venous catheter, parenteral nutrition, tumour and age >75 years. Overall, 30-day mortality in IMWs was significantly higher than that in other wards (51.1% vs. 38.2%, p <0.02). Multiple logistic regression analysis identified the administration of antifungal treatment 48 h after having the first positive BC as an independent determinant of hospital mortality. Patients with candidaemia in IMWs account for a substantial proportion of patients with candidaemia and have higher mortality compared with patients in other wards.

Abstract
Despite a 35% decline in the mortality rate for infants aged <5 years over the past two decades, every year nearly 40% of all deaths in this age group occur in the neonatal period, defined as the first 28 days of life. New knowledge on molecular and biochemical pathways in neonatal diseases will lead to the discovery of new candidate biomarkers potentially useful in clinical practice. In the era of personalized medicine, biomarkers may play a strategic role in accelerating the decline in neonatal mortality by assessing the risk of developing neonatal diseases, by implementing tailored therapeutic treatment, and by predicting the clinical outcome. However, there is an urgent need to reduce the gap in translating newly acquired knowledge from bench to bedside. Traditional and candidate biomarkers for neonatal sepsis and necrotizing enterocolitis will be discussed in this review, such as C-reactive protein (CRP), procalcitonin (PCT), serum amyloid A (SAA), soluble form of CD14 subtype presepsin (sCD14-ST), lipolysaccharide binding protein (LBP), angiopoietins (Ang)-1 and -2, soluble form of triggering receptor expressed on myeloid cells (sTREM-1), soluble form of urokinase-type plasminogen activator receptor (suPAR), platelet-activating factor (PAF) and calprotectin. New frontiers in managing critically ill newborns may be opened by metabolomics, a diagnostic tool based on the recognition of metabolites contained in biological fluids. Metabolomics represents the passage from a descriptive science to a predictive science, having the potential to translate benchtop research to real clinical benefits.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a leading pathogen causing nosocomial infections. Many studies have shown that the restricted use of antibacterials is associated with a decline in resistance. To establish whether an intervention protocol designed to limit the use of cephalosporins can lower mRSA infection rates and impact on Gram-negative bacteria susceptibility in an intensive Care Unit (ICU), we conducted a prospective, non-randomized, before-after intervention study in an 18-bed ICU in Genoa, Italy. The intervention was a hospital antibiotic control policy and the observation was routine monitoring for nosocomial infections and antibiotic use, recording periodically the incidence density and MRSA prevalence. The intervention included a new antibiotic guideline that restricted the use of cephalosporins for all ICU inpatients. The analysis showed that the intervention determined a significant reduction in cephalosporin usage (-70.3%), while fluoroquinolones, mainly ciprofloxacin, increased after introduction of the antibiotic policy (+46.5%). A significant reduction in the percentage of MRSA infections (-30%) and heterogeneous susceptibility patterns in Klebsiella pneumoniae and Pseudomonas aeruginosa were noted.

Abstract
The therapy for urinary infections is advised according to the antibiogram; the symptoms request an empirical therapy based on urinary infections knowledge and drugs spectrum activity. We considered the urinoculture performed on 3834 patients, 3012 male and 822 female, hospitalized in our Institute in the period between 01/01/2005 and 31/10/2006; 444 of these were positive (12.7 % - 451 bacterial strains). Table 1: bacterial strains isolaed. We reported some evaluations obtained by antibiogram. E. coli strains Ciprofloxacin sensitive resulted in 60% of cases. Enterococcus species and Enterococcus faecalis strains Ampicillin sensitive resulted in 96.4% and 100% of cases, respectively. In this study there is a Gram negative prevalence, whereas we had previously observed an equivalence between Gram negative and Gram positive (p 0.001). These data are useful for empirical therapy.

Abstract
Assaying calcitonin (CT) in the wash-out fluid from fine-needle aspiration biopsies (CT-FNAB) could be useful in the diagnosis of medullary thyroid carcinoma (MTC). The aim of this study was to correlate serum CT with cytology and CT-FNAB. Twenty-seven subjects (age range 27-75 yr) were studied. FNAB was performed in a thyroid nodule (no.=16) or lymph-node (no.=1 previously operated on for MTC) or in the prevalent nodule of multinodular goiters (no.=10). CT-FNAB values obtained in 37 subjects with normal serum CT (<10 ng/l) who underwent FNAB for thyroid nodules served as a negative control. In these subjects, CTFNAB values were 8.2+/-6.4 ng/l (range 2-30 ng/l). In patients with a thyroid nodule under evaluation for MTC, serum CT and CT-FNAB values were 14.5+/-3.9 ng/l (range 10-24 ng/l) and 16.4+/-29.8 ng/l (range 2-144 ng/l), respectively. In 4 patients, CT-FNAB values were higher than the highest values found in our negative controls (30 ng/l), but cytology results were compatible with a benign thyroid lesion and pentagastrin testing was negative. In 3 cases with CT-FNAB <30 ng/l, cytology was indicative of an indeterminate or probably follicular malignant lesion and histology was negative for MTC. None of the other subjects in whom pentagastrin testing was conducted showed serum CT values >100 ng/l. Our data do not show any correlation between CT-FNAB and serum CT. In conclusion, borderline CT values in patients with thyroid nodules are not rare. Our experience suggests that CT-FNAB does not have the same importance as that reported in the literature for thyroglobulin and PTH assay in wash-out fluid after FNAB in malignant thyroid and hyperfunctioning parathyroid lesions.

Abstract
BACKGROUND Some extra-thyroid effects of TSH have been described in vitro and in vivo. TSH has recently been suggested to induce interleukin-6 secretion by adipocytes. Leptin is the main protein secreted by adipose tissue. OBJECTIVE The aim of our study was to evaluate the acute effect of the recombinant human TSH (rhTSH)-induced TSH surge on serum leptin levels in thyroidectomized patients undergoing levothyroxine (L-T4) suppressive therapy for differentiated thyroid carcinoma (DTC). DESIGN A cohort of 15 female DTC patients was evaluated. Standard rhTSH testing was performed. Leptin, TSH, thyroid hormones, and thyroglobulin were measured before and 3, 6, and 9 days after rhTSH testing. Some metabolic parameters were also evaluated at the baseline. RESULTS Baseline leptin levels were 12.2+/-3.2 microg/l. Only body mass index (BMI) correlated significantly (p<0.05) with leptin levels. After rhTSH administration, TSH levels increased significantly (p<0.001), while thyroid hormones remained unchanged. Twenty hours after the last rhTSH administration, leptin (11.8+/-3.0 microg/l) levels were unchanged. The maximal TSH level was negatively related with BMI (p<0.05), but no correlation between maximal TSH and leptin levels after rhTSH was noted. CONCLUSIONS Our in vivo experimental model suggests that an acute TSH increase after rhTSH testing is ineffective in changing circulating leptin levels.

Abstract
Early diagnosis and treatment of neonatal sepsis are essential to prevent severe and life threatening complications. Consequently, rapid diagnostic tests capable to differentiate infected from non-infected newborns have the potential to make a significant impact on neonatal care. A new real-time polymerase chain reaction (PCR; LightCycler SeptiFast test M GRADE) has been proposed in the routine assessment of neonatal sepsis for the detection and identification of bacterial and fungal DNA from microorganisms which cause approximately 90% of all blood stream infections. The LightCycler SeptiFast test can detect and identify simultaneously the 25 most important bacterial and fungal species causing bloodstream infections within few hours by using a small volume of a single whole blood sample. Real-time PCR can be easily incorporated into the hospital setting for term or near-term infants admitted to the neonatal intensive care unit for sepsis evaluation.

Abstract
AIM Inflammation is considered to be one of the main mechanisms for the development and progression of peripheral arterial disease (PAD). Many studies have demonstrated that maximal exercise enhances the acute inflammatory response in claudicant patients, but no one has assessed the duration of this acute inflammatory activation. The aim of this study was to assess of the inflammatory pattern in claudicants and of the inflammatory response after maximal exercise and during the recovery from calf pain. METHODS Eleven patients with moderate claudication (MC) (age: 60.5+/-5.8 years; body mass index [BMI]: 27.5+/-4.6; absolute claudication distance [ACD]: 165.4+/-38), 10 patients with severe claudication (SC) (age: 60.3+/-5 years; BMI: 27+/-4.5; ACD: 91+/-11.3) and 8 healthy subjects (age: 59.4+/-6.8; BMI: 28.7+/-4.16) underwent to maximal treadmill test (speed 2.5 km/h, slope 15%). At rest, just after stop of the exercise (appearance of calf pain in patients, and 6 min of treadmill in controls) the circulating levels of interleukin (IL)-1beta and IL-6 have been measured. STATISTICAL ANALYSIS variance of mean values, Bonferroni t-test, split plot variance model, variance of d stop-before and stop-recovery have been utilized. P<0.05 has been considered the significant cut-off of the differences. RESULTS The maximal exercise excited significant (P<0.01) inflammatory activation in all patients: MC (rest IL-1beta: 1.55, 3.3 at stop; rest IL-6: 5.97, 8.38 at the stop); SC (rest IL-1beta: 2.97, 5.72 at stop; rest IL-6: 6.98, 9.99 at the stop). During recovery, MC showed a reduction of the inflammatory activation, whilst SC showed further increase (IL-1beta: 7.55; IL-6: 11.94). CONCLUSION The study confirms the higher inflammatory activation in claudicants and its enhancement after maximal exercise. During recovery, we found two kinds of response: type 1 (controls and MC), in which inflammation subsides, and type 2 (SC) characterized by further inflammatory increase. This trend is not univocal: 3 MC showed a type 2 response and 2 SC showed a type 1. In conclusion, inflammatory activation may depend not only on the degree of endothelial damage, but also on the individual inflammatory attitude, better assessed after maximal exercise than baseline values. This individual inflammatory responsiveness, considering the role of the rest measurement of markers of inflammation recently discussed, could be a useful marker for aggressive PAD.

Abstract
OBJECTIVE To investigate the value of serum C reactive protein (CRP) as a marker of erosive osteoarthritis (EOA) of the hand. METHODS Ninety eight patients, 67 with EOA and 31 with non-EOA of the hand, were included in the study and analysed for radiographic score (RS), number of erosions, and joint count (JC) at clinical observation and at bone scintigraphy. CRP was assayed in a serum sample by a highly sensitive immunonephelometric method. RESULTS The median (interquartile range) CRP level was 4.7 (2.4-6.9) mg/l in the EOA and 2.1 (0.5-4.9) mg/l in the non-EOA group (p = 0.001). In all patients, CRP correlated with RS (r(s) = 0.43, p<0.001), and mainly with JC at clinical observation (r(s) = 0.72, p<0.001) and at bone scintigraphy (r(s) = 0.47, p<0.001). The correlation of CRP with RS and JC was confirmed at clinical observation and at bone scintigraphy in the EOA subgroup, but only with JC at clinical observation in the non-EOA subgroup. CONCLUSIONS CRP levels are higher in EOA than in non-EOA patients. These levels probably reflect the disease activity of EOA, as suggested by correlations between CRP and JC at clinical observation and at bone scintigraphy.

Abstract
The study aim was to evaluate urinary excretion of Retinol Binding Protein (RBP), compared with urinary excretion of N-acetyl-beta-D-glucosaminidase (NAG), in preterm infants with anoxia and netilmicin treatment. Urinary RBP and NAG were evaluated in 83 preterm newborns divided in 4 groups: 37 healthy preterm newborns (controls); 14 with neonatal anoxia; 16 treated with ampicillin + netilmicin; 16 with neonatal anoxia and treated with ampicillin + netilmicin. RBP was determined by an automated nephelometric technique and NAG by a colorimetric method on 5-h urine samples in the first week of life. Results showed that urinary excretion of RBP (average from first week values) was 1.06+/-0.67 g/mol creatinine (mean +/- SD) in controls, 1.99+/-1.41 in antibiotic-treated newborns, 3.99+/-4.57 in anoxic newborns and 3.75+/-3.48 in anoxic newborns under antibiotic treatment. When gestational age was not considered, a marked effect of anoxia (P<0.001) and a borderline effect of netilmicin (P<0.059) on RBP excretion were detected by ANOVA. However when gestational age was also considered by analysis of covariance, it appeared as the strongest predictor of RBP excretion (P<0.001), while the effect of netilmicin was no longer significant (P=0.181). The effect of anoxia persisted, although less remarkable (P=0.010). Conversely anoxia did not affect urinary NAG excretion, which was rather correlated with gestational age and netilmicin administration. The authors conclude that RBP and NAG urinary excretion may be used to discriminate between neonatal anoxia and netilmicin treatment, respectively as etiologic factors of renal tubular damage in the newborn.

Abstract
Several studies have demonstrated the important role of growth factors, particularly epidermal growth factor (EGF) and transforming growth factor alpha (TGFalpha), in cellular growth after renal damage. EGF is mainly synthesized by the kidney. Many studies indicate that urinary EGF concentration significantly decreases in patients with acute and chronic renal failure. In this study we determined urinary EGF concentrations in children with renal and/or urological pathologies. We investigated 38 patients, 17 males and 21 females, of 3.34+/-2.96 years (mean +/- standard deviation), who were followed in the Nephrologic Unit of the Pediatric Department of the University of Verona for recurrent urinary tract infections: seven of these had vesicoureteric reflux and 4 had hypodysplasia. The results were compared with those from a healthy age-matched group of 44 children. In all patients, we assessed renal function including an examination of the urine with a microbiological evaluation. Moreover, a renal ultrasound and a voiding cystourethrogram were performed.

Abstract
In this study, we examine C-reactive protein (CRP) and serum amyloid protein A (SAA). Although the former is the best known and most commonly used indicator of inflammation, certain considerations underline the inadequacy of CRP determination alone for the early diagnosis of infection. In fact symptoms often precede the CRP elevation. SAA protein comprises a family of polymorphic apolipoproteins produced mainly by the liver, and several studies have stressed its importance in the diagnosis and monitoring of various diseases. Pathological SAA values are often detected in association with normal CRP concentrations. SAA rises earlier and more sharply than CRP. Finally, contrary to CRP, SAA presents the same trend in viral as well as bacterial infections. Although the data available on SAA in neonates are currently very limited, it is possible to postulate a role of primary importance for SAA in the management of neonatal infections.

Abstract
Human cystatin C, a basic low molecular mass protein with 120 amino acid residues, is freely filtered by the glomerulus and almost completely reabsorbed and catabolized by the proximal tubular cells. Cystatin C has been recently proposed as a new sensitive endogenous serum marker for the early assessment of changes in the glomerular filtration rate. To define a reference basis for future clinical investigations in the perinatal period, we investigated the relationship between maternal and neonatal serum cystatin C in comparison with that of creatinine. We also defined reference values in healthy women at full-term pregnancy and in full-term newborns over the first 5 days of life. Seventy-eight women with uncomplicated pregnancy, aged between 19 and 40 years, and their infant newborns (43 males, 35 females) were enrolled in the study. The gestational age ranged from 37 to 43 weeks, and the birth weight from 2.50 to 4.15 kg. Blood samples were taken from all the women immediately before delivery and from their newborns at birth, 72 and 96 h after birth. Maternal and neonatal renal function was evaluated by standards parameters and by calculating creatinine clearance. In all serum samples, we measured cystatin C, creatinine, and urea. At term gestation, serum cystatin C ranged from 0.64 to 2.30 mg/L. At birth, serum cystatin C values ranged from 1.17 to 3.06 mg/L, significantly decreasing after 3 and 5 days of life. No correlation was found between maternal and neonatal serum cystatin C values (r = 0.09). As cystatin C serum levels in newborns are not significantly correlated with the respective maternal levels, neonatal serum cystatin C may originate almost exclusively in the neonate.

Abstract
BACKGROUND The aaim of this study is to investigate the tubular damage markers in pre-eclampsia and in pregnancy induced hypertension (PIH). METHODS This transversal study involved 111 women admitted to the Department of Obstetric and Gynaecology, University Hospital, Padua (Italy) and was conducted from the 24th week until delivery: 23 had normal pregnancies, 54 manifest pre-eclampsia, and 34 manifested pregnancy-induced hypertension (PIH) without superimposed pre-eclampsia. The following laboratory tests were performed: U-alpha 1 microglobulin, U-NAG, uric acid and microalbuminuria. The four groups were compared using the Mann-Whitney test and the Kruskall-Wallis test for multiple comparisons. A value of p < 0.05 was considered as statistically significant. RESULTS As for the markers of tubular damage, the values for urinary NAG were significantly lower in the control group (0.97 U/mmol Creat) than in the pre-eclampsia group (2.89 U/mmol Creat), and the PIH group (2.12 U/mmol Creat) (p < 0.01). Values for urinary alpha 1-microglobulin were higher in the pre-eclampsia group (4.03 U/mmol Creat) than in the control (0.74 U/mmol Creat), and PIH groups (1.88 U/mmol Creat) (p < 0.01). As for the markers of glomerular damage, the values of microalbuminuria were higher in the pre-eclampsia group (134 micrograms/min) than in the control (9.4 micrograms/min), and PIH groups (10 micrograms/min), (p < 0.05). Uric acid, the marker of glomerular and tubular damage, was higher in the pre-eclampsia group (0.27 mmol/L) than in the control (0.20 mmol/L), and PIH groups (0.24 mmol/L), (p < 0.05). CONCLUSIONS In pre-eclampsia there is a tubular and glomerular damage to point out by an increased urinary excretion of NAG. In pre-eclampsia, an increase of urinary alpha 1-microglobulin excretion may be considered to be partly due to the overloading of the tubule and partly due to a mixed glomerular and tubular lesion.

Abstract
OBJECTIVE The aim of this work is to assess the most widespread methods currently proposed and two new markers for predicting the development of pre-eclampsia in pregnant women with hypertension. METHODS The study involved 212 pregnant Caucasian women: 104 normotensive, 68 pregnancy-induced hypertensive and 40 chronic hypertensive. Blood and urine were sampled between 28 and 30 weeks gestation. All 108 hypertensive pregnant women, at the time of sampling, demonstrated proteinuria below 0.3 g/24 h. The following laboratory tests were performed: fibronectin, antithrombin-III, alpha-1-microglobulin, U-N-acetyl-beta-glucosaminidase, uric acid and albumin excretion rate. Student's t-test, discriminant analysis and chi2 (chi-square) test were used as statistical methods. A P value less than 0.05 was considered significant. RESULTS After discriminating analysis, only three of the six variables analyzed were able to discriminate patients who would develop pre-eclampsia from the remaining hypertensive pregnant women: microalbuminuria, uric acid and fibronectin (chi2 = 29.122, P < 0.01). CONCLUSIONS In agreement with previous studies, albumin excretion rate appeared to be the best predictive test for pre-eclampsia in hypertensive pregnant women, giving a higher positive predictive value and specificity (87.5 and 98.9%, respectively).

Abstract
Cystatin C is a small basic protein with a MW of 13,359 Daltons, consisting of a non-glycosylated polypeptide chain containing 120 amino-acid residues. Cystatin C is produced in all the nucleated cells of the human body and its output rate is constant. The kidney is the main catabolic site of cystatin C, since the protein, by virtue of its low MW and its positive charge at normal pH, is freely filtered by the glomerulus and almost completely reabsorbed, catabolised and broken down in the cells of the proximal convoluted tubule. It is practically entirely filtered via the glomerular membrane, without any significant tubular secretion. The constant production rate of cystatin C in all the tissues, its elimination via the glomerular filter and its non-dependence on many extrinsic factors, including sex, age, diet, inflammation, are potentially ideal conditions for an endogenous biochemical marker of glomerular filtration. A recent method for determining cystatin C, is based on an immune reaction, could increase its clinical application. Not many studies have been conducted to date on cystatin C in children. The cystatin C concentration was higher during the first few days of life (range: 1.64-2.59 mg/L) with a rapid reduction during the first 4 months. Beyond the first year of life, cystatin C concentration became constant, with a reference range of 0.7-1.38 mg/L. On the basis of the data currently available, neonatal serum cystatin C would appear to derive from the newborn itself. In fact no correlations were found between maternal and neonatal serum cystatin C values. Cystatin C determination appears to be at least equivalent to serum creatinine measurement for the assessment of glomerular filtration rate in children. Further extended studies are needed to investigate these aspects more thoroughly in neonates.

Abstract
Peridontal disease is a frequent complication of diabetes, and diabetic subjects often exhibit decreased immune response with increased susceptibility to infection. We evaluated the possible relationship between immune response and periodontal disease in 40 type II diabetic patients, mean (+/- SD) age 59 +/- 8 years and mean disease duration 17 +/- 4 years, with good metabolic control (mean fasting plasma glucose, 10.5 +/- 3.8 mM/L, mean HbA1c 8.1 +/- 1.66%), and in 40 age and gender-matched controls. Interproximal alveolar bone loss (ABL), as the percentage of bone loss from the cement enamel junction (CEJ) to the apex, was measured with a modified Schei ruler at the deepest point on the mesial/distal surface of the teeth, except third molars, on a panoramic radiograph. Immunological evaluation involved study of NADPH neutrophil superoxide production, neutrophil chemotaxis, lymphocyte subpopulations, immunoglobulins and complement. Diabetic patients showed significant differences compared with controls regarding ABL (30.6 +/- 14.7% versus 17.6 +/- 4.3%; p < 0.0001) and the T-helper/T-suppressor ratio (2.3 +/- 1.0% versus 1.8 +/- 0.8%; p < 0.05). Other parameters of cell-mediated immunity and humoral immune response did not show any significant variations. No correlation between immunological and radiographic analysis parameters were found. Further studies are needed to verify the exact role played by immunological factors in type II diabetic patients with periodontal disease.

Abstract
Human cystatin C is a low molecular mass protein of 13359 Dalton recently proposed as a new very sensitive marker of changes in glomerular filtration rate. Serum cystatin C concentration correlates negatively with glomerular filtration rate as well as or better than creatinine. We evaluated a recently introduced automated nephelometric immunoassay for cystatin C in serum or EDTA-plasma samples on the Behring Nephelometer System. The assay consists of incubating the 100-fold diluted sample for 6 minutes with latex particles covalently coated with anti-human cystatin C antibodies, and then quantifying the change of light-scatter produced. Method reproducibility is satisfactory, the intra- and inter-assay coefficients of variation ranging from 1.58% to 3.77% and from 5.6% to 11.47% respectively. Rheumatoid factor (< or = 1116 IU/ml), bilirubin (< or = 418 micrommol/l), triglycerides (10.47 mmol/), and haemoglobin (12 g/l) do not significantly interfere in the assay. No significant difference was found in cystatin C concentration between serum and EDTA-plasma samples. Cystatin C is stable in serum samples stored under different conditions up to one month. This method correlates well (mean difference=-0.536+/-0.307 mg/l) with another commercially available particle-enhanced turbidimetric immunoassay. Cystatin C offers better clinical sensitivity than creatinine for discriminating patients with normal renal function and those with mild-to-moderate reduction in renal function. This method is suitable for routine cystatin C measurement, including emergencies.

Abstract
The literature does not contain reports regarding teicoplanin overdose in newborns. In a neonate with a history of recent postasphyctic acute renal failure which recovered within 7 days of life, antibiotic therapy with teicoplanin was started for sepsis due to Staphylococcus hominis. However, for 5 days the dosage was excessive (20 mg/kg twice daily instead of an initial dose of 16 mg/kg and then doses of 8 mg/kg once daily). Once this error had been noted, therapy was immediately suspended. Clinically the newborn had improved and blood culture at the end of the therapy was negative. Biohumoral tests revealed constantly normal levels of serum creatinine, serum cystatin C and blood nitrogen. Urinary parameters of tubulotoxicity were also within normal values. Urinary epidermal growth factor was increased. Teicoplanin was well tolerated at the renal level in the newborn even in this case of excessive dosage.

Abstract
Human cystatin C is a basic low molecular mass protein (13,359 Dalton) freely filtered through the glomerulus and almost completely re-absorbed and catabolized by proximal tubular cells. We measured serum cystatin C in 38 kidney transplant patients (23 males, 15 females) aged between 6 and 32 years. To assess renal function, serum and urinary creatinine were also determined in all patients, and creatinine clearance was finally calculated. Cystatin C was determined by a particle-enhanced turbidimetric assay, and creatinine was measured by gas chromatography-mass spectrometry. To compare the diagnostic efficiency of cystatin C with that of creatinine, inulin clearance was performed on 12 renal transplant patients, and receiver operating characteristic (ROC) analysis was applied. The results of this study demonstrate that serum cystatin C significantly increases in renal transplant patients with reduced creatinine clearance (< 70 mL/min per 1.73 m2) and that the diagnostic accuracy of serum cystatin C is better than of serum creatinine. Cystatin C may be utilized as a very marker of reduced GFR.
