["Naked" exit-site for peritoneal dialysis catheters].

Exit site infections (ESI) and peritoneal catheter tunnel infections are strongly associated with peritonitis. Alternative exit-site dressings can include the use of water and soap and the absence of sterile gauze. This article reports our experience with "naked" exit-sites, meaning without any kind of gauze to cover them. From January 2017 to October 2020, we enrolled 38 patients of the Nephrology and Dialysis Unit of the "San Martino" Hospital in Belluno. Nine of these patients had a "naked" exit-site. At the end of the study, no significant differences were found in the percentage of ESI-free patients, in the incidence rate of ESI, in the relative risk of developing ESI and in the incidence rate of peritonitis.

[Home Hemodialysis: new organizational models to favor the economic and environmental sustainability in the province of Belluno].

The prevalence of chronic kidney disease is 7.05% in Italy. The replacement dialysis treatments determine greenhouse gas emissions thus contributing to climate change, an important source of risk to global health. Furthermore, the percentage of the Italian Gross Domestic Product destined to public health expenditure has progressively contracted. The province of Belluno has an area of 3610 km2, with a population density of 56 people/km2, an old age index of 248.5, and offers 4 dialysis centers; however, several patients take up to 8 hours/week to commute to the dialysis center, with a consequent significant environmental and economic impact. We have investigated the Home Hemodialysis (H-HD) models, both as Assisted Home Hemodialysis (AH-HD), and as Not-assisted Home Hemodialysis (NH-HD), to evaluate their environmental and economic sustainability, and the actual impact due to their adoption by 5 patients. Thanks to AH-HD it is possible a reduction up to 3767 kg of CO2 per year, and an economic saving of € 32 456 per year. Utilizing a NH-HD treatment, it is possible a reduction of 5330 kg of CO2 per year, and a reduction in annual healthcare costs up to € 30 156 per year. Furthermore, the adoption of H-HD treatment for 5 patients allowed an effective reduction of 14 537 kg of CO2 emitted and a net economic saving of € 57 975. Therefore, we consider H-HD methods a valid option for patients living in areas with low population density, where transports have a significant impact, allowing a net reduction of CO2 equivalent emissions and a considerable saving of the health resources.

[EBV-ASSOCIATED PNEUMONIA IN PATIENT WITH GRANULOMATOSIS WITH POLYANGIITIS (GPA) IN IMMUNOSOPPRESSIVE THERAPY TREATED WITH ACICLOVIR].

Granulomatosis polyangiitis (GPA) is an ANCA-related vasculitis (AAV) whose clinical manifestations mainly concern the respiratory tract (upper and lower) and the kidney. The treatment of GPA (as well as other AAV) includes the use of immunosuppressive drugs with numerous side effects; the most frequent complications are infectious and neoplastic. GPA frequently relapses. Epstein Barr Virus (EBV) is a ubiquitous virus; it is estimated that about 90% of the world's population has BEEN EXPOSED TO with this pathogen and has subsequently developed a latent infection. Under certain conditions including immunosuppression EBV may reactivate. We report the clinical case of a 67-year-old woman who presented with GPA involving the upper respiratory tract and renal failure with the need for hemodialysis treatment. The fourth month of induction therapy with cyclophosphamide and methylprednisone she presented with dyspnea and respiratory failure. After excluding pulmonary embolism and heart failure, a series of investigations including high resolution tomography and fibroscopy with broncoalveolar lavage (BAL) were performed which excluded recurrence of pulmonary vasculitis including alveolar haemorrhage A BAL demonstrated EBV-DNA. On this basis EBV pneumonia was diagnosed, and antiviral therapy with acyclovir was begun, followed by clinical and radiological improvement. In patients with GPA treated with immunosuppressive drugs pulmonary involvement may not only be due to the underlying vasculitis, but also to opportunistic agents, which must always be considered.
