ABSTRACT

INTRODUCTION: This study aims to assess the association of piperacillin/tazobactam and meropenem minimum inhibitory concentration (MIC) and beta-lactam resistance genes with mortality in the MERINO trial. METHODS: Blood culture isolates from enrolled patients were tested by broth microdilution and whole genome sequencing at a central laboratory. Multivariate logistic regression was performed to account for confounders. Absolute risk increase for 30-day mortality between treatment groups was calculated for the primary analysis (PA) and the microbiologic assessable (MA) populations. RESULTS: In total, 320 isolates from 379 enrolled patients were available with susceptibility to piperacillin/tazobactam 94% and meropenem 100%. The piperacillin/tazobactam nonsusceptible breakpoint (MIC >16 mg/L) best predicted 30-day mortality after accounting for confounders (odds ratio 14.9, 95% confidence interval [CI] 2.8-87.2). The absolute risk increase for 30-day mortality for patients treated with piperacillin/tazobactam compared with meropenem was 9% (95% CI 3%-15%) and 8% (95% CI 2%-15%) for the original PA population and the post hoc MA populations, which reduced to 5% (95% CI -1% to 10%) after excluding strains with piperacillin/tazobactam MIC values >16 mg/L. Isolates coharboring extended spectrum ß-lactamase (ESBL) and OXA-1 genes were associated with elevated piperacillin/tazobactam MICs and the highest risk increase in 30-day mortality of 14% (95% CI 2%-28%). CONCLUSIONS: After excluding nonsusceptible strains, the 30-day mortality difference from the MERINO trial was less pronounced for piperacillin/tazobactam. Poor reliability in susceptibility testing performance for piperacillin/tazobactam and the high prevalence of OXA coharboring ESBLs suggests that meropenem remains the preferred choice for definitive treatment of ceftriaxone nonsusceptible Escherichia coli and Klebsiella.

ABSTRACT

BACKGROUND: Invasive fungal infections (IFIs) represent a global issue and affect various patient populations. In recent years, resistant fungal isolates showing increased azole or echinocandin MICs have been reported, and their potential clinical impact has been investigated. AIMS: To provide an update on the epidemiology of resistance among fungi (e.g., Candida spp., Aspergillus spp., and Cryptococcus spp.) and to offer a critical appraisal of the relevant literature regarding the impact of MICs on clinical outcome in patients with IFI. SOURCES: PubMed search with relevant keywords along with a personal collection of relevant publications. CONTENT: Although antifungal resistance has been associated with a poorer response to antifungal therapy in various studies, other factors such as comorbidities, septic shock and source of infection appear to be key determinants affecting the clinical outcome of patients with IFI. IMPLICATIONS: Future international collaborative studies are required to tease out the relative contribution of in vitro antifungal resistance on patient outcomes, thus enabling the optimization of IFI management.

ABSTRACT

Despite the occurrence of several earthquakes, only a few studies were conducted in Italy on the psychological impact in children and adolescents, with data mostly collected within one year after the disaster. This cross-sectional study aimed at exploring the prevalence of both post-traumatic stress disorder (PTSD) and emotional/behavioral difficulties, as well as at identifying their main predictors, among youths 2 years after the earthquake that hit Northern Italy in 2012. 682 children and adolescents (9-14 years) living in two districts (earthquake zone vs control zone) were administered an exposure questionnaire, the UCLA PTSD-Index for DSM-IV, and the Strengths and Difficulties Questionnaire (SDQ) and 1162 parents were assessed through the Symptom Checklist-90 (SCL-90). The prevalence of a likely PTSD in the earthquake zone was 1.9% (4.4% near the epicenter) and the total PTSD score in the affected area was significantly higher than in the control zone. 14.9% of youths living in the earthquake zone had a borderline/abnormal SDQ total difficulties score and 87.5% of youth with a likely PTSD also had a SDQ total score in the borderline/abnormal range. Regression analysis showed that the number of lifetime traumatic events (e.g., death of a relative) was the best predictor of children/adolescents psychological difficulties 2 years after the earthquake, followed by severity of exposure (personal injuries and losses) and parental psychopathology. Despite some limitations, this study highlights that youths may exhibit PTSD symptoms years after disasters, often in comorbidity with behavioral/emotional difficulties, stressing the need for long-term surveillance and interventions in exposed populations.

ABSTRACT

The posology of tacrolimus (TAC) is usually guided by its therapeutic drug monitoring. Some patients reach target concentrations (CTs) quickly, others more slowly. In a retrospective study, 20 kidney transplant recipients were included (mean age, 50.7 ± 14.1 years; weight 64.0 ± 14.2 kg; patients clinically stable for over a year). We studied cytochrome CYP3A5 genotype, in particular CYP3A5 6986A>G, the most important polymorphism related to the metabolism of TAC (wild genotype CYP3A5 *1 genotype, and CYP3A5 *3 variants). One year after transplantation, the CTs were 5.0 to 8.0 ng/mL. The patients were divided into group A (TAC doses < 6.0 mg/d) and group B (TAC doses > 6.0 mg/d). All were tested for the CYP3A5 gene sequence to characterize their polymorphism. Patients with CYP3A5 *1/*1 and *1/*3 were extensive metabolizers, and those with CYP3A5 *3/*3 were poor metabolizers. In group A and group B, the average TAC doses at the time of therapeutic drug monitoring were 3.0 ± 1.4 ng/mL (0.05 ± 0.03 mg/kg) and 12.8 ± 3.7 ng/mL (0.2 ± 0.1 mg/kg), respectively (P < .001). Group A was the poor metabolizers genotype, while in group B, the extensive metabolizers genotype was present. Patients with the CYP3A5 *1/*1 or *1/*3 genotype required 1.5 to 2 times higher doses than patients *3/*3 to reach CT. This genetic test allows clinicians to know, before the kidney transplant, the patient's TAC metabolism pattern and then to optimize the drug exposure.

ABSTRACT

Pneumocystis jiroveci pneumonia in non-HIV patients is infrequent and characterized by atypical presentations and increased severity. Although hematogenous dissemination from the lungs can lead to extrapulmonary infections, isolation of oocysts from blood in human subjects has not been documented. We report a case of P. jiroveci pneumonia with persistent isolation of oocysts from blood and positivity of P. jiroveci polymerase chain reaction. The patient presented with bilateral diffuse pulmonary nodules and received prolonged treatment with trimethoprim/sulfamethoxazole.

ABSTRACT

The aim of the study was to compare the effect of Self-Adjusting Files (SAF) and WaveOne Primary file with syringe and needle irrigation on the filling ability of oval-shaped root canals obturated with thermoplasticized gutta-percha. Twenty-four single root teeth with single oval-shaped root canals were distributed into two experimental homogeneous groups. One group was instrumented and cleansed using the SAF system while in the other group the WaveOne system with syringe and needle irrigation was used. After instrumentation, the roots were filled by Thermafil Obturators and TopSeal sealer. Specimens were transversally sectioned at 2-, 5- and 7-mm levels from the apex and observed under light microscope. The percentage of gutta-percha filled area (PGFA), the percentage of sealer filled area (PSFA) and the percentage of voids area (PVA) were measured for each section, moreover the percentage of completely filled sections was evaluated. At all levels, no significant differences in terms of PGFA, PSFA, PVA and percentage of completely filled canals between groups were obtained (P > 0.05). On the contrary, when the data were pooled, the mean PGFA in the SAF group was 95.8%, whereas it was 93.2% in the WaveOne group (P less than 0.05). The percentage of sections completely filled was 77.8% in the SAF group, and 52.8% in the WaveOne group (P less than 0.05). Overall, the use of the SAF system in oval canals allows to obtain a significantly greater complete filling than the use of the WaveOne system.

ABSTRACT

BACKGROUND: The World Health Organization's Action Framework for tuberculosis elimination in low-tuberculosis incidence countries includes the screening for active and latent tuberculosis in selected high-risk groups, including health care workers. In this context, medical and health profession students, exposed to nosocomial tuberculosis transmission during training and clinical rotations, are target populations for tuberculosis screening. No updated data are available on tuberculosis screening practice and knowledge of medical and health profession students in Italy. METHODS: Within the activities Italian Study Group on Hospital Hygiene of the Italian Society of Hygiene, Preventive Medicine and Public Health, we carried out a multicentre cross-sectional study to assess knowledge, attitude and practices on tuberculosis prevention and control among Medical, Dentistry, Nursing and other health professions' students. Students were enrolled in the study on a voluntary basis and were administered a previously piloted structured questionnaire. Logistic regression models were applied to explore knowledge on tuberculosis prevention by selected socio-demographic variables and University-based tuberculosis prevention practice. RESULTS: Students of seventeen Universities across Italy participated in the study, and 58.2% of them received compulsory tuberculin skin test either at enrollment or while attending clinical practice. A total of 5,209 students filled the questionnaire. 37.7% were medicine and dentistry students (Group 1), 44.9% were nursing students (Group 2) and 17.4% were other health professions' students (Group 3). Age and gender had different distributions by groups, as well as knowledge and practice on tuberculin skin test. 84.4% of the study population (95% CI = 83.3-85.3) was aware of the existence of the tuberculin skin test, 74.4% (95% CI = 73.2-75.6) knew what is the first-level screening test for latent tuberculosis and only 22.5% (95% CI = 21.4-23.6) knew how to proceed after a positive tuberculin skin test result. Overall, knowledge on tuberculosis prevention was higher in Group 2 and lower Group 3, as compared to Group 1. CONCLUSION: In Italy, the knowledge on tuberculosis screening among University students is generally good. To reduce some of the criticalities found among the different study courses, it would be appropriate to harmonize both the regulations on tuberculosis screening practices for admission to University courses, and the educational activities on the topic of tuberculosis, to be extended to all workers involved in health care setting.

ABSTRACT

The occurrence of illicit drugs (cocaine, opioids, amphetamines and cannabis derivatives), some of their metabolites and 48 pharmaceuticals, was investigated in pool and source waters in ten Italian indoor swimming pools. The samples were analyzed by highperformance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS), after solid phase extraction (SPE). Cocaine and its metabolites were found in nine swimming pools, at concentrations from 0.3 to 4.2 ng/L for cocaine, 1.1 to 48.7 ng/L for norcocaine, 0.7 to 21.4 ng/L for benzoylecgonine and 0.1 to 7.3 ng/L for norbenzoylecgonine. Opioids, amphetamines and cannabis derivatives were never detected. The most frequent pharmaceuticals were anti-inflammatory drugs: ibuprofen was found in all the pool waters, with a maximum 197 ng/L and ketoprofen was detected in 9/10 samples (maximum 127 ng/L). Among anticonvulsants, carbamazepine and its metabolite, 10,11-dihydro-10,11dihydroxycarbamazepine, were frequent in swimming pool water (8/10 samples) at concentrations up to 62 ng/L. The cardiovascular drug valsartan was also found frequently (8/10 samples), but at lower concentrations (up to 9 ng/L). Other pharmaceuticals were detected occasionally and at lower concentrations (atenolol, enalapril, paracetamol, hydroclorothiazide, irbesartan and dehydro-erythromycin). Carbamazepine, irbesartan and dehydroerythromycin were detected at very low levels (up to 5 ng/L) in only one of the four source water samples. A quantitative risk assessment showed that the health risk for humans to these substance in swimming pool waters was generally negligible, even for vulnerable subpopulations such as children and adolescents.

ABSTRACT

BACKGROUND: Klebsiella pneumoniae carbapenemase (KPC)-producing K. pneumoniae (KPC-KP) has become one of the most important contemporary pathogens, especially in endemic areas. AIMS: To provide practical suggestion for physicians dealing with the management of KPC-KP infections in critically ill patients, based on expert opinions. SOURCES: PubMed search for relevant publications related to the management of KPC-KP infections. CONTENTS: A panel of experts developed a list of 12 questions to be addressed. In view of the current lack of high-level evidence, they were asked to provide answers on the bases of their knowledge and experience in the field. The panel identified several key aspects to be addressed when dealing with KPC-KP in critically ill patients (preventing colonization in the patient, preventing infection in the colonized patient and colonization of his or her contacts, reducing mortality in the infected patient by rapidly diagnosing the causative agent and promptly adopting the best therapeutic strategy) and provided related suggestions that were based on the available observational literature and the experience of panel members. IMPLICATIONS: Diagnostic technologies could speed up the diagnosis of KPC-KP infections. Combination treatment should be preferred to monotherapy in cases of severe infections. For non-critically ill patients without severe infections, results from randomized clinical trials are needed for ultimately weighing benefits and costs of using combinations rather than monotherapy. Multifaceted infection control interventions are needed to decrease the rates of colonization and cross-transmission of KPC-KP.

ABSTRACT

Intraabdominal candidiasis (IAC) is the second most frequent form of invasive candidiasis, and is associated with high mortality rates. This study aims to identify current practices in initial antifungal treatment (IAT) in a real-world scenario and to define the predictors of the choice of echinocandins or azoles in IAC episodes. Secondary analysis was performed of a multinational retrospective cohort at 13 teaching hospitals in four countries (Italy, Greece, Spain and Brazil), over a 3-year period (2011-2013). IAC was identified in 481 patients, 323 of whom received antifungal therapy (classified as the treatment group). After excluding 13 patients given amphotericin B, the treatment group was further divided into the echinocandin group (209 patients; 64.7%) and the azole group (101 patients; 32.3%). Median APACHE II scores were significantly higher in the echinocandin group (p 0.013), but IAT did not differ significantly with regard to the Candida species involved. Logistic multivariate stepwise regression analysis, adjusted for centre effect, identified septic shock (adjusted OR (aOR) 1.54), APACHE II >15 (aOR 1.16) and presence in surgical ward at diagnosis (aOR 1.16) as the top three independent variables associated with an empirical echinocandin regimen. No differences in 30-day mortality were observed between groups. Echinocandin regimen was the first choice for IAT in patients with IAC. No statistical differences in mortality were observed between regimens, but echinocandins were administered to patients with more severe disease. Some disagreements were identified between current clinical guidelines and prescription of antifungals for IAC at the bedside, so further educational measures are required to optimize therapies.

ABSTRACT

Since the introduction of combined antiretroviral therapy, human immunodeficiency virus (HIV) infection is no longer a contraindication for solid organ transplantation. In HIV/hepatitis C virus (HCV)-coinfected patients undergoing liver transplantation, HCV-related cirrhosis, drug-drug interactions, and calcineurin inhibitors-related toxicity affect clinical outcomes. Therapeutic drug monitoring can be useful to assess antiretroviral over- or underexposure in this cohort. We report the clinical characteristics along with antiretroviral trough levels of maraviroc, darunavir, and etravirine in 3 HIV/HCV-coinfected liver transplant recipients who developed post-transplant liver cirrhosis.

ABSTRACT

Surgical site infections (SSIs) are a frequent cause of morbidity following surgical procedures. Gram-positive cocci, particularly staphylococci, cause many of these infections, although Gram-negative organisms are also frequently involved. The risk of developing a SSI is associated with a number of factors, including aspects of the operative procedure itself, such as wound classification, and patient-related variables, such as preexisting medical conditions. Antimicrobial prophylaxis (AP) plays an important role in reducing SSIs, especially if patient-related risk factors for SSIs are present. The main components of antimicrobial prophylaxis are: timing, selection of drugs and patients, duration and costs. Compliance with these generally accepted preventive principles may lead to overall decreases in the incidence of these infections. Ideally the administration of the prophylactic agent should start within 30 minutes from the surgical incision. The duration of the AP should not exceed 24 hours for the majority of surgical procedures. The shortest effective period of prophylactic antimicrobial administration is not known and studies have demonstrated that post-surgical antibiotic administration is unnecessary. Furthermore, there were no proven benefits in multiple dose regimens when compared to single-dose regimens. The choice of an appropriate prophylactic antimicrobial agent should be based primarily on efficacy and safety. Broad spectrum antibiotics should be avoided due to the risk of promoting bacterial resistance. Cephalosporins are the most commonly used antibiotics in surgical prophylaxis; specifically, cefazolin or cefuroxime are mainly used in the prophylaxis regimens for cardio-thoracic surgery, vascular surgery, hip or knee arthroplasty surgery, neurosurgical procedures and gynecologic and obstetric procedures. A review of the prophylactic regimens regarding the main surgical procedures is presented.

ABSTRACT

Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome characterized by stenoses of the internal jugular veins (IJVs) and/or azygos veins and formation of collateral venous channels. A case of a 57-year-old patient with CCSVI in whom the venous outflow from the left IJV to the right atrium occurred through a venous anomaly, the persistent left superior vena cava (PLSVC), is reported. PLSVC is caused by persistence of the left anterior cardinal vein that drains blood from the limb effluent from the left and the left side of head and neck into coronary sinus (Type a), or in the left atrium (Type b). PLSVC can be associated either with innominate vein hypoplasia or other congenital heart abnormalities. Because of evidence of left innominate vein hypoplasia, angioplasty was not performed using the ordinary route but passing with the balloon directly through the PLSVC up to the left IJV. Finally, angioplasty was carried out in a standard manner in the right IJV as well as in the azygous vein. Confirmation angiogram revealed complete reopening of all treated vessels with no evidence of peri- and postoperative complications. The patient was discharged home the following day in good general conditions. PLSVC is a rare congenital vein anomaly but in case of concomitant innominate vein hypoplasia may prove to be a valuable alternative to treat patients with IJV diseases.

ABSTRACT

A Burkholderia cepacia complex outbreak occurred among ventilated non-cystic fibrosis patients in an intensive care unit (ICU) in Italy: 33 colonized and 13 infected patients were included in a retrospective study aimed at investigating factors related to clinical infection and mortality. Demographic/clinical conditions and mortality did not vary significantly between colonized and infected patients, both groups showing high mortality rates compared with the overall ICU population and similar to that observed in patients with other infections. In multivariate regression analysis, disease severity (defined by the Simplified Acute Physiology Score II) and age were the only independent predictors of early mortality (odds ratio: 1.12; 95% confidence interval: 1.02-1.26; and 1.07; 1.01-1.15, respectively).

ABSTRACT

BACKGROUND: Implementing infection control measures in light of healthcare-associated infection (HAI) surveillance data can prevent HAIs. Surveillance has been associated with a reduction of HAI in intensive care unit (ICU) patients, though the reasons for this improvement remain unclear. AIM: To evaluate changes in healthcare-associated infection (HAI) rates during three surveys of the Italian Nosocomial Infections Surveillance in Intensive Care Units (ICUs) network (SPIN-UTI) six-year project and to explore sources of variation of indicators of HAI in the 65 participating ICUs. METHODS: The SPIN-UTI network adopted the European protocols for patient-based HAI surveillance. Cumulative incidence, incidence density, infection rates adjusted for device-days, and device utilization ratios were calculated for each survey and compared. To identify risk factors multiple logistic regression analyses were performed. Crude excess mortality was computed as the difference between the crude overall case-fatality rate of patients with and without HAI. FINDINGS: The risk of ICU-acquired infections increased in the third survey compared with previous (relative risk: 1.215; 95% confidence interval: 1.059-1.394). Among risk factors, the number of hospitalized patients requiring ICU admission and the Simplified Acute Physiology Score II increased from 73.7% to 78.1% and from 37.9% to 40.8% respectively. Although mortality rates remained unchanged, HAIs trebled the risk of death. Acinetobacter baumannii was the most frequently reported micro-organism in the third survey (16.9%), whereas in the previous surveys it ranked third (7.6%) and second (14.3%). CONCLUSIONS: The study highlighted the increased risk of HAI, at least partially explained by the greater severity and number of hospitalized patients requiring ICU admission. Furthermore, the management of intubation procedures and of ventilated patients was identified as a potential target for infection control interventions to decrease the growing risk of HAI in ICUs.

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

The advent of combined antiretroviral therapy (cART) dramatically changed the view of human immunodeficiency virus (HIV) infection as an exclusion criterion for solid organ transplantation, resulting in worldwide reports of successful transplants in HIV-infected individuals. However, there are few reports on simultaneous pancreas-kidney transplant in HIV-positive recipients detailing poor outcomes. A series of four pancreas-kidney transplant performed on HIV-infected individuals between 2006 and 2009 is presented. All recipients reached stably undetectable HIV-RNA after transplantation. All patients experienced early posttransplant infections (median day 30, range 9-128) with urinary tract infections and bacteremia being most commonly observed. In all cases, surgical complications led to laparotomic revisions (median day 18, range 1-44); two patients underwent cholecystectomy. One steroid-responsive acute renal rejection (day 79) and one pancreatic graft failure (month 64) occurred. Frequent dose adjustments were required due to interference between cART and immunosuppressants. At a median follow-up of 45 months (range, 26-67) we observed 100% patient survival with CD4 cell count >300 cells/mm(3) for all patients. Although limited by its small number, this case series represents the largest reported to date with encouraging long-term outcomes in HIV-positive pancreas-kidney transplant recipients.

ABSTRACT

The aim of the present study was to investigate the environmental and healthy aspects from a representative sample of indoor swimming pools located in the Emilia Romagna region. During the sampling sessions, the occupational environment was evaluated in terms of microclimate parameters and thermal comfort/discomfort conditions. Moreover the chemical risk was assessed by analyzing from the pool water the presence of disinfection by-products (DBPs), such as: trihalomethanes (THMs), haloacetic acids (HAAs), chlorite, chlorate and bromate. The analytical results are in agreement with the Italian legislation (Accordo Stato-Regioni; 2003) even if in some of the sampled indoor swimming pools, the dosed combined chlorine levels, were greater than the Italian limit. With the regard to the microclimate conditions evaluation, the considered thermal indices, Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD%), described a satisfactory occupational environment. Among DBPs, the THMs mean levels (41.4 +/- 30.0 microg/l) resulted close to the values of the current Italian drinking water legislation, and seem to not represent an health issue. The pool waters chlorate levels (range: 5 - 19537 microg/l) need further investigations as recent epidemiological studies on drinking water hypothesized a potential genotoxicity effect of these compounds which are involved in cellular oxidative processes.

ABSTRACT

Cryptococcosis is a disseminated fungal disease typically associated with immunosuppression and characterized by high mortality rates. Cryptococcus neoformans has been reported to be isolated from blood cultures in around 20% of patients with cryptococcosis, and cryptococcemia has been correlated with poor prognosis. We report a case of fatal C. neoformans fungemia in a neutropenic patient with a history of chronic lymphocytic leukemia treated with alemtuzumab. The patient presented with loss of consciousness and died after 5 days of antifungal therapy with liposomal amphotericin B. The international literature regarding opportunistic infections after immunosuppressive therapy with alemtuzumab with particular attention on fungal infections has also been reviewed.
