Abstract
BACKGROUND Survival is a key metric of the effectiveness of a health system in managing cancer. We set out to provide a comprehensive examination of worldwide variation and trends in survival from brain tumors in adults, by histology. METHODS We analyzed individual data for adults (15-99 years) diagnosed with a brain tumor (ICD-O-3 topography code C71) during 2000-2014, regardless of tumor behavior. Data underwent a 3-phase quality control as part of CONCORD-3. We estimated net survival for 11 histology groups, using the unbiased nonparametric Pohar Perme estimator. RESULTS The study included 556,237 adults. In 2010-2014, the global range in age-standardized 5-year net survival for the most common sub-types was broad: in the range 20%-38% for diffuse and anaplastic astrocytoma, from 4% to 17% for glioblastoma, and between 32% and 69% for oligodendroglioma. For patients with glioblastoma, the largest gains in survival occurred between 2000-2004 and 2005-2009. These improvements were more noticeable among adults diagnosed aged 40-70 years than among younger adults. CONCLUSIONS To the best of our knowledge, this study provides the largest account to date of global trends in population-based survival for brain tumors by histology in adults. We have highlighted remarkable gains in 5-year survival from glioblastoma since 2005, providing large-scale empirical evidence on the uptake of chemoradiation at population level. Worldwide, survival improvements have been extensive, but some countries still lag behind. Our findings may help clinicians involved in national and international tumor pathway boards to promote initiatives aimed at more extensive implementation of clinical guidelines.

Abstract
Purpose The impact of SARS-CoV-2 pandemic on other pathogens is largely unknown. We aimed to compare the prevalence of vaccine-preventable invasive bacterial infections before and during the pandemic in Piedmont (Italy). Methods We defined the monthly incidence of S. pneumoniae, H. influenzae and N. meningitides-invasive diseases from January 2010 to June 2021. Then, we compared the mean monthly cases during the previous 5 years (2015–2019) and the monthly cases in 2020 or 2021. Results We found significant reductions for invasive pneumococcal diseases (IPDs) in adults and H. influenzae-invasive diseases in 2020 and 2021 in comparison to the previous years, but not for invasive meningococcal diseases and IPDs in children. Conclusions Further data are needed to confirm these findings and define possible post-pandemic evolutions in the epidemiology of vaccine-preventable invasive bacterial diseases.

Abstract
BACKGROUND AND OBJECTIVE We aimed to evaluate the safety and outcomes of thrombectomy in anterior circulation acute ischaemic stroke recorded in the SITS-International Stroke Thrombectomy Register (SITS-ISTR) and compare them with pooled randomized controlled trials (RCTs) and two national registry studies. METHODS We identified centres recording ≥10 consecutive patients in the SITS-ISTR with at least 70% of available modified Rankin Scale (mRS) at 3 months during 2014-2019. We defined large artery occlusion as intracranial internal carotid artery, first and second segment of middle cerebral artery and first segment of anterior cerebral artery. Outcome measures were functional independence (mRS score 0-2) and death at 3 months and symptomatic intracranial haemorrhage (SICH) per modified SITS-MOST. RESULTS Results are presented in the following order: SITS-ISTR, RCTs, MR CLEAN Registry and German Stroke Registry (GSR). Median age was 73, 68, 71 and 75 years; baseline NIHSS score was 16, 17, 16 and 15; prior intravenous thrombolysis was 62%, 83%, 78% and 56%; onset to reperfusion time was 289, 285, 267 and 249 min; successful recanalization (mTICI score 2b or 3) was 86%, 71%, 59% and 83%; functional independence at 3 months was 45.5% (95% CI: 44-47), 46.0% (42-50), 38% (35-41) and 37% (35-41), respectively; death was 19.2% (19-21), 15.3% (12.7-18.4), 29.2% (27-32) and 28.6% (27-31); and SICH was 3.6% (3-4), 4.4% (3.0-6.4), 5.8% (4.7-7.1) and not available. CONCLUSION Thrombectomy in routine clinical use registered in the SITS-ISTR showed safety and outcomes comparable to RCTs, and better functional outcomes and lower mortality than previous national registry studies.

Abstract
OBJECTIVES Since the introduction of the β-lactam/β-lactamase inhibitor ceftazidime-avibactam (CZA), rapid evolution of resistance has been reported in different KPC-producing Klebsiella pneumoniae isolates. In this multicenter retrospective study, we describe the emergence of CZA resistance and evaluate the mutations that might be responsible for the restoration of carbapenem susceptibility. METHODS During a study period of 18 months, KPC-producing K. pneumoniae isolates of five hospitalized patients were collected with phenotypic development of CZA resistance. RESULTS In vitro restoration of carbapenem susceptibility during treatment was observed in 3 isolates. Whole genome sequencing of these isolates showed a D179Y mutation in the KPC gene of 2 variants and a KPC-2 with a Δ242-GT-243 deletion (KPC-14). Two KPC-3 variants showed CZA resistance with sustained carbapenemase activity without genomic adaptations in the KPC gene. CONCLUSIONS This study confirms the emergence of CZA resistance in KPC K. pneumoniae. The role of carbapenems in treating patients with these variants is unclear and combination therapies warrant further investigation.

Abstract
We prospectively compared the performance of RESIST-5 O.O.K.N.V. and NG-Test Carba 5 assays directly from blood cultures spiked with 130 characterized Enterobacterales isolates. Overall, both assays yielded 100% sensitivity to detect KPC-type carbapenemases and OXA-48-like carbapenemases. Both assays failed to detect KPC-31 and KPC-33, D179Y point mutation variants of KPC-3 and KPC-2, that are deprived of carbapenemase activity and confer resistance to ceftazidime-avibactam. On blood culture bacterial pellets, NDM- and VIM-type carbapenemases were detected in 50.0% and 52.2%, respectively, by RESIST-5 O.O.K.N.V. vs 100% by NG-Test Carba 5. The sensitivity of RESIST-5 O.O.K.N.V. improved to 100% and 95.6%, respectively, by performing the assay on 4-h early subculture.

Abstract
INTRODUCTION Bacterial lower respiratory tract infections (BLRTI) may represent serious clinical conditions which can lead to respiratory failure, intensive care unit admission and high hospital costs. The detection of carbapenemase- and extended-spectrum β-lactamase (ESBL)-producing Enterobacterales, as well as meticillin-resistant Staphylococcus aureus (MRSA), has become a major issue, especially in healthcare-associated infections. This study aimed to determine whether molecular assays could detect genes encoding carbapenemases, ESBL and MRSA directly from respiratory samples in order to expedite appropriate therapy and infection control for patients with BLRTI. METHODS The carbapenem-resistant enterobacterales (CRE), ESBL and MRSA/SA ELITe MGB assays were performed directly on 354 respiratory specimens sampled from 318 patients admitted with BLRTI. Molecular results were compared with routine culture-based diagnostics results. RESULTS Positive (PPV) and negative (NPV) predictive values of the CRE ELITe MGB kit were 75.9% [95% confidence interval (CI) 60.3-86.7] and 100%, respectively. PPV and NPV of the ESBL ELITe MGB kit were 80.8% (95% CI 63.6-91.0) and 99.1% (95% CI 96.6-99.8), respectively. PPV and NPV of the MRSA/SA ELITe MGB kit were 91.7% (95% CI 73.7-97.7)/100% and 98.3% (95% CI 89.8-99.3)/96.8% (95% CI 81.6-99.5), respectively. DISCUSSION Validity assessment of molecular assays detecting the main antibiotic resistance genes directly from respiratory samples showed high accuracy compared with culture-based results. Molecular assays detecting the main carbapenemase, ESBL, S. aureus and meticillin resistance encoding genes provide an interesting tool with potential to expedite optimization of antibiotic therapy and infection control practices in patients with BLRTI.

Abstract
BACKGROUND Invasive non-tuberculous mycobacteria (NTM) infections are emerging worldwide in patients undergoing open-chest cardiac bypass surgery exposed to contaminated heater-cooler units (HCUs). Although this outbreak has been investigated by culturing bacteria isolated from HCU aerosol and water samples, these conventional methods have low-analytic sensitivity, high rates of sample contamination, and long turnaround time. AIM To develop a simple and effective method to detect NTM in HCUs by real-time polymerase chain reaction (PCR), with a short laboratory turnaround time and reliable culture results. METHODS A total of 281 water samples collected from various HCUs at seven Italian hospitals were simultaneously screened for NTM by a propidium monoazide (PMA)-PCR assay and by conventional culture testing. The results were analysed with culture testing as the reference method. FINDINGS (i) The agreement between culture testing and PMA-PCR was 85.0% with a cycle threshold (CT) cut-off value of <38 vs 80.0% with a CT of <43, with a moderate Cohen's κ-coefficient; (ii) the CT cut-off value of <42 was deemed more suitable for predicting positive specimens; (iii) given the low concentration of target DNA in water samples, the minimum volume to be tested was 1 L. CONCLUSION The use of PMA-PCR for fast detection of NTM from environmental samples is highly recommended in order to ascertain whether HCUs may represent a potential source of human exposure to NTM. This reliable and simple method reduces laboratory turnaround time compared to conventional methods (one to two days vs eight weeks, respectively), thereby improving control strategies and effective management of HCUs.

Abstract
We herein report the case of a young immunocompetent adult patient with a rapidly fatal haemophagocytic lymphohistiocytosis syndrome related to human herpesvirus 1 (HHV-1) infection, with herpetic hepatitis and persistent high-level viraemia despite treatment with acyclovir. Haemophagocytic lymphohistiocytosis was confirmed in the patient's spleen and bone marrow. HHV-1 DNA was extracted from whole blood and liver biopsy and the UL23 gene was sequenced. A V348I natural polymorphism of the TK protein was found in blood and liver specimens. Further studies are needed to investigate the role of this polymorphism in the development of systemic immune dysregulation.

Abstract
Epstein-Barr virus (EBV) is a γ-herpes virus, responsible for infectious mononucleosis in immunocompetent hosts. Cellular immunity appears rapidly during EBV primary infection, keeping it silent despite long-life persistence in B lymphocytes. Defects of the EBV-specific cellular immunity are supposed to be the basis of post-transplantation lymphoproliferative disorders, promoted by high levels of immunosuppression. We retrospectively reviewed 197 solid organ transplant recipients to investigate EBV-specific lymphocyte responsiveness using Enzyme-linked ImmunoSpot assay (EliSpot), which assesses the EBV-specific interferon (IFN)-γ producing peripheral blood mononuclear cells, and kinetics of EBV infection/reactivation post-transplantation using quantitative real-time polymerase chain reaction (PCR) on whole blood. Overall, 102 of the 197 patients (51.8%) showed EBV responsiveness at the EBV-EliSpot assay: 68 (66.6%) showed a persistently positive EBV response in 3 or more determinations and 34 (33.3%) had transient episodes of nonresponsiveness. Ninety-five (48.2%) patients were persistently EBV nonresponders. EBV-DNAemia data were available for 58 patients: 27.6% presented at least one episode of EBV-DNA occurrence. No differences were found in EBV-EliSpot response stratification between the groups of patients who experienced episodes of EBV reactivation and those without EBV-DNAemia. However, EBV DNAemia peak values tended to be higher in the first year post-transplantation in the group of patients with a persistent positive EBV-specific immune response. EBV viral load quantitation in blood and EliSpot EBV-specific immune response determination may represent a powerful tool for monitoring solid organ transplant recipients, guiding immunosuppression modulation in patients with active EBV replication.

Abstract
Cellular immune response has been demonstrated to play a role in the control of human cytomegalovirus (HCMV) replication in organ transplant recipients. Herein, HCMV-specific T-cell response and association to the onset of organ infection/disease were prospectively evaluated by EliSPOT assay in a population of 46 lung transplant (LT) recipients at 1, 3, 6, 9 and 12 months post-transplantation. According to our centre's practice, a combined prolonged antiviral prophylaxis (HCMV-IG for 12 months and ganciclovir or valganciclovir for 3 weeks from postoperative day 21) was given to all LT recipients. HCMV-DNA was concomitantly detected on bronchoalveolar lavage (BAL) and whole blood by real-time PCR. Approximately one third of patients resulted HCMV persistently non-responder; the rate of HCMV infection, as evaluated by HCMV-DNA positivity, tended to be higher in non-responders. Mean viral load on BAL was significantly higher in non-responders vs other patients (p <0.001). Temporal profile of infections appeared related to the HCMV responder status with a shorter time to onset of infection post-transplantation and a longer duration in non-responders. The occurrence of organ disease (i.e. pneumonia) tended to be higher in non-responders, with poor prognosis, as death occurred in one of three non-responder patients that developed HCMV pneumonia. The lack of HCMV-specific cellular response can contribute to the onset of organ infection and disease also in patients in which antiviral prophylaxis was adopted; this could be due to the potential occurrence of incomplete control of replication in lungs or a delayed priming of T-cell reconstitution.

Abstract
The occurrence and clinical impact of herpes simplex virus (HSV) were evaluated in 342 bronchoalveolar lavage specimens from 237 patients. HSV-1 and HSV-2 were detected in 32.1% and <1% of patients, respectively. A significant difference of HSV-1 prevalence and load was found in relation to admission to intensive care unit, mechanical ventilation and mortality within 28 days; in particular, a viral load ≥10(5) copies/mL bronchoalveolar lavage fluid was significantly associated with critical features. No association was found with immune status or other characteristics. Nine of 21 (42.9%) cases of ventilator-associated pneumonia were positive for HSV-1, with poor outcome in six.

Abstract
Evaluation of BK virus replication is a fundamental tool in the monitoring of renal transplant recipients. Herein, we investigated the role of urine VP1 messenger RNA (mRNA) quantification and combined measurement of serum DNA and urine VP1 mRNA in 428 kidney allograft recipients. BK viremia and viruria were detected in 24 (5.6%) and 54 (12.6%) patients, respectively. A diagnosis of BKV-associated nephropathy (BKVAN) was established in 2 patients, both within the first year posttransplantation. Based on urine VP1 mRNA measurement, BKV replication was observed in 10 (2.1%) patients, 2 of whom displayed BKVAN. Urine VP1 mRNA was detected in all cases in association with viremia except 5 and in all cases with viruria. No difference among VP1 mRNA levels was noted between the 2 BKVAN patients and the highest values in patients without BKVAN. The urine VP1 mRNA result by analysis using the operating characteristics was not superior to viremia, despite the improvement obtained with the combined measurement of viremia (cut-off, 16,000 copies/mL) and urine VP1 mRNA (>10,000 copies/10(3) cells). In conclusion, VP1 mRNA measurements may complement viremia and viruria to monitor BKV replication, although its use is limited by its technical complexity in comparison with DNA detection.

Abstract
AIM The aim of this study was to report most recent data regarding the occurrence of influenza A virus H1N1v in the lower respiratory tract from a cohort of hospitalized adult patients during the winter season 2009/2010 and investigated the main clinical features and outcomes. METHODS A total of 130 consecutive BAL specimens (collected from October 2009-March 2010) of 101 patients were retrospectively analyzed for influenza A virus H1N1v positivity using a commercial kit. RESULTS Overall, 19/130 (14.6%) BAL specimens from 17/101 (16.8%) patients were positive for the novel influenza A H1N1v virus. H1N1v resulted significantly more prevalent in immunocompetent subjects. As regards clinical features, H1N1v resulted more prevalent in respiratory insufficiency or acute respiratory illness. Thirteen patients died during the analytic period; three of them (23.1%) resulted positive to H1N1v but no direct association has been made. CONCLUSION Our cohort study of influenza A H1N1v detection in BAL from hospitalized adult patients confirms the overall moderate clinical impact of this virus, as reported in most reports worldwide. It remains to be evaluated the role of reassortment with influenza virus strains circulating in the winter season 2010/2011 and its potential pathogenicity.

Abstract
AIM The recently described polyomaviruses KI and WU have been detected in respiratory samples, stools, tonsils, and blood, particularly in immunocompromised conditions, although little is known about tissue tropism. Herein we investigated the occurrence of KIV and WUV in non-malignant tonsillar specimens by Real-time quantitative PCR; the presence of polyomaviruses BK, JC and SV40-DNA was also evaluated. METHODS Twenty-nine non-malignant tonsil specimens obtained from children and adults admitted for tonsillectomy were prospectively studied. Real-time quantitative TaqMan PCR for polyomaviruses KI, WU, BK, JC, and SV40 were performed. RESULTS KI-DNA was positive in 2/29 tonsillar specimens (6.9%), while BK- DNA, JC-DNA, SV-40 DNA, and WU-DNA sequences were not identified. CONCLUSION Few studies have investigated the prevalence of polyomaviruses in tonsil specimens, with varying results, and data are particularly scant as regards the newly discovered KIV and WUV. Two major questions remain to be definitely answered at this regard: the possibility that human tonsils represent the initial site of infection and/or a latency site and the biological and clinical meaning of KIV and WUV in different contexts and groups of patients, in that it is not clear whether they are simple bystanders or play a role in tonsil disease.

Abstract
The newly discovered polyomaviruses KI and WU (KIV and WUV) were isolated from secretions of patients with respiratory symptoms as well as in blood, spleen, lymphoid tissues, and stools, especially in immunocompromised conditions. The aim of this work was to evaluate the prevalence of KIV and WUV in bronchoalveolar lavage (BAL) from lung transplant recipients. We also examined potential correlations between these viruses and occurrences of pneumonia, acute respiratory insufficiency, or other acute respiratory conditions and acute rejection episodes. Discharge diagnosis was based on the International Classification of Diseases-Italian version 2002, based on the 9th-revision clinical modification. A rejection episode was diagnosed by transbronchial lung biopsy in accordance with the 2007 International Society for Heart and Lung Transplantation Working Formulation. Overall, we analyzed 53 BALs obtained from 24 transplant recipients. Positive polymerase chain reaction results were observed in 6 samples (11.3%) from 6 patients (25%), versus 7 samples (13.2%) from 7 patients (29.2%) for KIV and WUV, respectively. Regarding the diagnosis of pneumonia, the prevalence was 22.2% and 33.3% for KIV and WUV, respectively. In cases of acute respiratory insufficiency or other acute respiratory conditions, 2 out of 9 samples were positive for KIV (22.2%) and 4 out of 9 for WUV (44.4%). An Acute rejection episode (ARE) was diagnosed in 7 instances among 6 lung transplant patients: The corresponding BAL specimens showed positive results for KIV in 3 out of 7 (42.8%) cases with ARE vs 3 out of 46 (6.5%) without an ARE (P < .05), and for WUV in 3 out of 7 (42.8%) vs 4 out of 46 (8.7%) (P < .05), respectively. Although the small number of specimens limits the statistical analysis, our results showed a higher prevalence of WUV compared with KIV. The compromised pulmonary environment in the lung allograft may cause reactivation of these viruses. Their roles in this context need to be further evaluated.

Abstract
The monitoring of herpesvirus infection plays a central role in lung transplantation (LT). Herein we evaluated the prevalence of human cytomegalovirus (HCMV), human herpesvirus-6 (HHV-6), human herpesvirus-7 (HHV-7), and Epstein-Barr Virus (EBV) DNA in bronchoalveolar lavage (BAL) and transbronchial biopsy (TBB) specimens from LT patients. We associated the findings with the occurrence of interstitial pneumonia, acute rejection, or organizing pneumonia. Viral DNA was detected using real-time polymerase chain reaction (PCR) on 76 paired samples (BAL and TBB) from 27 patients who were receiving a universal combined prophylaxis (cytomegalovirus [CMV] immunoglobulin [Ig] + gancyclovir or valgancyclovir). Histopathological analysis was performed in accordance with the International Society for Heart and Lung Transplantation (ISHLT) criteria. Overall, HCMV results were positive in 25/76 (32.9%) specimens (BAL and/or TBB); HHV-6 in 16 (21.1%); HHV-7 in 40 (52.6%); and EBV in 13 (17.1%). Interstitial pneumonia was diagnosed in 6/76 (7.9%) cases: 5 (83.3%) were positive to HCMV (combined specimens; P < .0001); 5 (83.3%) to HHV-7; and 2 (33.3%) to EBV. An acute rejection episode was diagnosed in 19/76 (25%) cases: 7 (36.8%) were positive to HCMV; 5 (26.3%) to HHV-6; 10 (52.6%) to HHV-7, and 3 (15.8%) to EBV. No significant association was observed between virus detection or load and acute rejection. Organizing pneumonia was diagnosed in 4/76 (5.3%) cases: 1 (25%) positive to HCMV; 4 (100%) to HHV-6 (P < .05); 2 (50%) to HHV-7; and none to EBV. In conclusion, the prevalence of HCMV tended to be lower than that reported in the literature, confirming the importance of universal combined prophylaxis. HCMV was a relevant agent for interstitial pneumonia; although the small numbers limit the statistical analysis, our data did not support an association between herpesviruses and acute rejection episodes, whereas the role of HHV-6 in the pathogenesis of organizing pneumonia deserves further study. Viral detection on TBB could represent an adjunctive tool to complement that on BAL.

Abstract
BACKGROUND Concomitant chemoradiotherapy (CT/RT) is the standard treatment of locally advanced squamous cell carcinoma of the head and neck (SCCHN). We evaluated the efficacy of induction docetaxel (Taxotere), cisplatin, and 5-fluorouracil (TPF) before CT/RT versus CT/RT alone. PATIENTS AND METHODS Patients with stage III-IVM0 SCCHN, Eastern Cooperative Oncology Group performance status of zero to one, were randomly assigned to receive CT/RT alone (arm A: two cycles of cisplatin 20 mg/m(2), days1-4, plus 5-fluorouracil 800 mg/m(2)/day 96 h continuous infusion, during weeks 1 and 6 of radiotherapy) or three cycles of TPF (arm B: docetaxel 75 mg/m(2) and cisplatin 80 mg/m(2), day 1, and 5-fluorouracil 800 mg/m(2)/day 96 h continuous infusion, every 3 weeks) followed by the same CT/RT. The primary end point was the rate of radiologic complete response (CR) at 6-8 weeks after the end of CT/RT. RESULTS A total of 101 patients were randomly allocated to the study (51 arm A; 50 arm B). CR rates were 21.2% (arm A) versus 50% (arm B). Median progression-free survival and overall survival were, respectively, 19.7 and 33.3 months (arm A) and 30.4 and 39.6 months (arm B). Hematologic and non-hematologic toxic effects during CT/RT were similar in the two arms. CONCLUSION Induction TPF followed by CT/RT was associated with higher radiologic CR in patients with locally advanced SCCHN with no negative impact on CT/RT feasibility.

Abstract
AIM The epidemiology of lower respiratory tract (LRT) viral infections in adults is probably underestimated and the high frequency of multiple viral infections complicates the evaluation of the possible role of the single viruses. The aim of this study was to investigate the clinical epidemiology and impact of respiratory viral pathogens, in particular of those singularly detected, in bronchoalveolar lavage (BAL) specimens from hospitalized adult patients. METHODS A panel for the detection of 16 respiratory viruses was used to prospectively evaluate 324 consecutive specimens obtained from 219 patients over a full-year period. RESULTS Two-hundred-twenty-one specimens (68.2%) were positive for at least one virus, 119/324 (36.7%) to a single viral agent. The most commonly detected viruses were herpesviruses HHV-7 (26.2%), human cytomegalo-virus (HCMV, 22.2%), HHV-6 (19.8%), EBV (12.7%), enteroviruses and rhinoviruses (both 11.7%), parainfluenza viruses (4.9 %), and metapneumovirus (4.0%). Human cytomegalo-virus was significantly more prevalent as single viral pathogen with a viral load >105 copies/ml associated to pneumonia in solid organ transplant recipients. Other viral pathogens might account for some cases of pneumonia or respiratory insufficiency, although multiple infections were common. CONCLUSIONS The use of a comprehensive diagnostic panel for respiratory viral infections may be useful to clarify the epidemiology and clinical impact of viral pathogens in hospitalized adult patients. The occurrence of multiple infections is a common finding and results should be interpreted taking into account the clinical context as well as viral load and the biological characteristics of each virus.

Abstract
We present the design and analysis of the first fully expressive, iterative combinatorial exchange (ICE). The exchange incorporates a tree-based bidding language (TBBL) that is concise and expressive for CEs. Bidders specify lower and upper bounds in TBBL on their value for different trades and refine these bounds across rounds. These bounds allow price discovery and useful preference elicitation in early rounds, and allow termination with an efficient trade despite partial information on bidder valuations. All computation in the exchange is carefully optimized to exploit the structure of the bid-trees and to avoid enumerating trades. A proxied interpretation of a revealed-preference activity rule, coupled with simple linear prices, ensures progress across rounds. The exchange is fully implemented, and we give results demonstrating several aspects of its scalability and economic properties with simulated bidding strategies.

Abstract
BACKGROUND Primary cutaneous T-cell lymphomas (CTCLs) are a heterogeneous group of lymphomas where the tumour population emerges within a multiple subclone pattern. Mycosis fungoides (MF) and Sézary syndrome (SS) are characterized by the expansion of clonal CD4+/CD45RO+ memory T cells. Lymphomatoid papulosis (LyP) is a chronic, lymphoproliferative disorder included in the CD30+ primary CTCL spectrum. Several studies have suggested a role of viral infection for super-antigenic activation of T lymphocytes; however, evidence of their association with CTCLs is still lacking. Human herpesvirus (HHV) 7 is a CD4+ T-lymphotropic herpesvirus; its restricted cellular tropism and the ability to induce cytokine production in infected cells could make it an important pathogenic cofactor in lymphoproliferative disorders. OBJECTIVES To investigate the presence of HHV7 DNA on CTCL and healthy skin donors (HD). METHODS We used quantitative real time polymerase chain reaction to evaluate the potential pathogenic role of HHV7. RESULTS Twenty-seven of 84 (32.1%) HD were positive for HHV7 DNA. Twenty-one of 148 (14.2%) patients with CTCLs were positive for HHV7 DNA: nine of 39 (23.1%) SS, six of 14 (42.9%) CD30+ CTCLs and six of 24 (25.0%) LyP, and HHV7 DNA was negative in all 71 patients with MF. CONCLUSIONS These results seem to exclude a pathogenic role of HHV7 in CTCLs, suggesting the possibility of skin as a latency site.

Abstract
AIM Human Cytomegalovirus (HCMV) is a relevant pathogen in transplant recipients, particularly in the first three months post-transplantation. The use of antiviral prophylaxis and pre-emptive therapy is able to reduce incidence of HCMV infection and disease. The incidence of HCMV infection and disease in renal transplant recipients in the first 100 days post-transplantation was investigated, in relation with HCMV serological matching and therapeutic management. METHODS Incidence of HCMV infection in the first 100 days post-transplantation was evaluated by pp65-antigenemia in 165 patients on a total number of 1241 clinical samples. Patients were divided in four groups according to donor/recipient serological matching: D(-)/R(-) (low risk of HCMV disease), D(-)/R+ and D+/R+ (intermediate risk) and D+/R(-) (high risk). Antiviral strategy (prophylaxis in high risk group; pre-emptive therapy in intermediate risk group, no therapy in low risk group) and immunosuppressive protocol were recorded. RESULTS Incidence of antigenemia-positivity was as follows: 0/3 D(-)/R(-) patients; 59/130 (45.4%) D+/R+; 5/16 (31.3%) D(-)/R+; 4/16 D+/R(-). No significative difference was found between the four groups in terms of incidence of antigenemia-positivity in the first 100 days following transplantation. Antigenemia values >50 pp65-positive/2x10(5) peripheral blood leukocytes (used to start pre-emptive therapy) were present in 18/130 (13.8%) D+/R+; 1/16 (6.2%) D+/R(-); 0/16 D(-)/R+. Viral kinetics in patients with HCMV infection was described. CONCLUSION No significative difference was found in terms of incidence of HCMV infection in the first 100 days post-transplantation in relation to immunosuppressive protocol and serological matching, suggesting the appropriateness of antiviral strategies and viral monitoring adopted in this setting.

Abstract
BACKGROUND Cyclophosphamide (CYC) is thought to be the most effective treatment for antineutrophil cytoplasmatic antibody (ANCA)-associated idiopathic systemic vasculitis with severe organ or life threatening presentation. The key mechanism of action of CYC is suppression of the B lymphocyte activity. However, a considerable minority of patients either remains refractory to conventional therapy or experiences dose-limiting side effects. METHODS In the present study, rituximab (4 weekly doses of 375 mg/m2 and 2 more doses at 1-month interval) was intravenously administered as a rescue therapy to 7 patients (4 affected by idiopathic systemic microscopic polyangiitis, 2 by Wegener's granulomatosis, and 1 affected by Churg Strauss syndrome). The study group was made up of 3 women and 4 men, mean age 61.5 years (39-71), intolerant or refractory to more conventional therapy. Four patients had histologically confirmed paucimmune necrotizing glomerulonephritis. RESULTS Significant decreases were observed in levels of serum creatinine, proteinuria, erythrocyte sedimentation rate, C-reactive protein, and ANCA titers within the first 12 months of follow-up. Arthralgia and weakness rapidly disappeared in all patients. Four out of five patients reported a decrease in the degree of paresthesia, paralleled by an improvement in the electrodiagnostic parameters. A significant improvement was observed in both Birmingham Vasculitis Activity Score and Vasculitis Damage Index. Side effects were negligible. CONCLUSION In this sample of patients with idiopathic systemic vasculitis that was refractory or intolerant to conventional treatment, rituximab was found to be a safe and effective rescue therapy.

Abstract
Polyomavirus BK (BKV) reactivation can occur in immunodeficient patients. Few studies on BKV infection in patients with systemic lupus erytematosus (SLE) nephritis are available. Aim of this study was to analyse the prevalence of BKV infection by quantifying viral load and to investigate the association with clinical and histological parameters indicating duration, type and activity of SLE.BKV-DNA was evaluated by polymerase chain reaction in serum (sBKV) and urine (uBKV) specimens from 40 patients with SLE nephritis and 29 healthy controls. Renal function, urinary activity, clinical index of SLE activity [SLE Disease Activity Index (SLEDAI) score], CD4+/CD8+ ratio, histological classes and duration of SLE nephritis were compared according to the BKV-DNA-positivity.sBKV was present in 15% of SLE patients and in 13.8% of controls; uBKV in 32% of SLE patients and in 17.2% of controls. There was no significant difference in terms of kidney function, urinary activity, SLEDAI score, presence of anti-dsDNA antibodies, CD4+/CD8+ ratio and BKV viremia and/viruria, as well as there was no significant correlation between SLEDAI score, anti-dsDNA antibodies titers and median viral load. Duration of nephropathy tended to be shorter in patients with BKV viremia and/or viruria; proteinuria/creatininuria ratio tended to be higher in patients with positive sBKV and uBKV. BKV-DNA-positivity tended to be more frequent in patients treated with an immunosuppressive agent versus those on steroid treatment. Reactivation of BKV infection can occur in patients with SLE, although prevalence data do not significantly differ from those obtained in the control group. The trend toward an association between BKV infection and degree of proteinuria and less duration of SLE nephritis could indicate a major susceptibility to develop BKV infection in more active phases of the disease. The role of BKV reactivation in terms of clinical parameters and histological pattern, as well as the role of therapeutic protocols in the onset of BKV reactivation and, conversely, the therapeutic implication of BKV reactivation in SLE patients remain to be defined and should be addressed in further studies on a larger number of patients.
