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 laboratorybased 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.

Vitamin K (vitamin K1 or phylloquinone and vitamin K2, a series of menaquinones [MKs]) is involved in the production of bone and matrix amino acid γ-carboxy-glutamic acid (Gla) proteins, regulating bone and vascular calcification. Low vitamin K concentrations are associated with increased risks of fractures and vascular calcification, and frequent complications in hemodialysis patients. We carried out an observational study to establish the prevalence of vitamin K deficiency and to assess the relationship between vitamin K status, vertebral fractures, vascular calcification, and survival in 387 patients on hemodialysis for ≤1 year. We determined plasma levels of vitamin K compound, bone-Gla-protein, matrix-Gla-protein, and routine biochemistry. Vertebral fractures (reduction in vertebral body height by ≤20%) and aortic and iliac calcifications were also investigated in a spine (D5-L4) radiograph. Three-year patient survival was analyzed. Important proportions of patients had deficiency of MK7 (35.4%), vitamin K1 (23.5%), and MK4 (14.5%). A total of 55.3% of patients had vertebral fractures, 80.6% had abdominal aorta calcification, and 56.1% had iliac calcification. Vitamin K1 deficiency was the strongest predictor of vertebral fractures (odds ratio [OR], 2.94; 95% confidence interval [CI], 1.38-6.26). MK4 deficiency was a predictor of aortic calcification (OR, 2.82; 95% CI, 1.14-7.01), whereas MK5 deficiency actually protected against it (OR, 0.38; 95% CI, 0.15-0.95). MK7 deficiency was a predictor of iliac calcification (OR, 1.64; 95% CI, 1.03-2.60). The presence of vertebral fractures was also a predictor of vascular calcifications (OR, 1.76; 95% CI, 1.00-3.08). Increased alkaline phosphatase and C reactive protein (CRP), age, and cerebrovascular events were predictors of mortality. Our study suggests that the vitamin K system may be important for preserving bone mass and avoiding vascular calcification in hemodialysis patients, pointing out a possible role of vitamin K in bone and vascular health. Based on our results, we suggest that the general population should also be studied for vitamin K deficiency as a possible cause of both vertebral fractures and vascular calcification. © 2012 American Society for Bone and Mineral Research.

Peritoneal Dialysis International | Year: 2014

Introduction: Acutely decompensated heart failure (HF) in patients with diuretic resistance is often treated with extracorporeal ultrafiltration. Peritoneal ultrafiltration (PUF) has been proposed for the long-term management of severe HF after resolution of the acute episode. The aim of the present study was to evaluate the use of PUF in the treatment of chronic refractory HF in patients without end-stage renal disease. Methods: This multicenter (10 nephrology departments throughout Italy) retrospective observational study included patients with severe HF refractory to maximized drug treatment. The patients were proposed for PUF because they had experienced at least 3 hospital admissions in the preceding year for acutely decompensated HF requiring extracorporeal ultrafiltration. Results: Of the 48 study patients (39 men, 9 women; mean age 74 ± 9 years), 30 received 1 nocturnal icodextrin exchange, 5 required 2 daily exchanges, and 13 received 2 – 4 sessions per week of automated peritoneal dialysis. During the first year, renal function remained stable (initial: 20.8± 10.0 mL/min/1.73 m2; end: 22.0 ± 13.6 mL/min/1.73 m2), while pulmonary artery systolic pressure declined to 40 ± 6.09 mmHg from 45.5 ± 9.18 mmHg (p = 0.03), with a significant concomitant improvement in New York Heart Association functional status. Hospitalizations decreased to 11 ± 17 days/patient–year from 43 ± 33 days/patient–year before the start of PUF (p < 0.001). The incidence of peritonitis was 1 episode in 45 patient–months. Patient survival was 85% at 1 year and 56% at 2 years. Conclusions: This study confirms the satisfactory results of using PUF for chronic HF in elderly patients. © 2014 International Society for Peritoneal Dialysis.

Infection | Year: 2014

Purpose: We compared the risk factors, the diagnostic tools and the outcome of filamentous fungal infections (FFIs) in hematological patients (HAEs) and non-hematological patients (non-HAEs). Methods: Prospective surveillance (2009-2011) of proven and probable FFIs was implemented in 23 Italian hospitals. Results: Out of 232 FFIs, 113 occurred in HAEs and 119 in non-HAEs. The most frequent infection was invasive aspergillosis (76.1% for HAEs, 56.3% for non-HAEs), and the localization was principally pulmonary (83.2% for HAEs, 74.8% for non-HAEs). Neutropenia was a risk factor for 89.4% HAEs; the main underlying condition was corticosteroid treatment (52.9%) for non-HAEs. The distribution of proven and probable FFIs was different in the two groups: proven FFIs occurred more frequently in non-HAEs, whereas probable FFIs were correlated with the HAEs. The sensitivity of the galactomannan assay was higher for HAEs than for non-HAEs (95.3 vs. 48.1%). The overall mortality rate was 44.2% among the HAEs and 35.3% among the non-HAEs. The etiology influenced the patient outcomes: mucormycosis was associated with a high mortality rate (57.1% for HAEs, 77.8% for non- HAEs). Conclusions: The epidemiological and clinical data for FFIs were not identical in the HAEs and non-HAEs. The differences should be considered to improve the management of FFIs according to the patients' setting. © The Author(s) 2013.

Journal of Vascular Access | Year: 2011

In dialysis patients, both central venous catheter (CVC) insertion and CVC use during the dialysis procedure pose important legal issues, because of potentially severe, even fatal, complications. The first issue is the decision of the kind of vascular access that should be proposed to patients: an arteriovenous (AV) fistula, a graft, or a CVC. The second issue, when choosing the CVC option, is the choice of CVC: nontunneled versus tunneled. Leaving a temporary nontunneled CVC for a prolonged time increases the risk of complications and could raise a liability issue. Even when choosing a long-term tunneled CVC, nephrologists should systematically explain its potential harms, presenting them as "unsafe for long-term use" unless there is a clear contraindication to an AV native or prosthetic access. Another critical issue is the preparation of a complete, informative, and easy-to-understand consent form. The CVC insertion procedure has many aspects of legal interest, including the choice of CVC, the use of ECG monitoring, the use of ultrasound guidance for cannulation, and the use of fluoroscopy for checking the position of the metal guidewire during the procedure as well as the CVC tip before the end of the procedure. Use of insertion devices and techniques that can prevent complications should obviously be encouraged. Complications of CVC use are mainly thrombosis and infection. These are theoretically expected as pure complications (and not as malpractice effects), but legal issues might relate to inappropriate catheter care (in both the inpatient and outpatient settings) rather than to the event per se. Thus, in the individual case it is indeed very difficult to establish malpractice and liability with a catheterrelated infection or thrombosis. In conclusion, we cannot avoid complications completely when using CVCs, but reducing them to a minimum and adopting safe approaches to their insertion and use will reduce legal liability. © 2011 Wichtig Editore.
