Background: The aim of this study was to evaluate the impact on the national health system of COVID-19 infection in vaccinated patients undergoing haemodialysis., Methods: From the cohort of vaccinated dialysis patients enrolled in 118 dialysis centres, we calculated hospitalisation incidence in COVID-19-infected subjects. COVID-19-related hospitalisations and ICU admissions were analysed over two time periods (prior to administration of the third dose and following administration of the third dose of vaccine) and adjusted for several co-variates. Using the general population as the reference, we then calculated the Standardized Incidence Ratio (SIR) of hospitalisation., Results: Eighty-two subjects out of 1096 infected patients were hospitalised (7.5%) and sixty-four hospitalisations occurred among the 824 infected persons after the third dose. Age ≥ 60 years (Adj RR 2.91; 95% CI 1.34-6.30) and lung disease (Adj RR = 2.45; 95% CI 1.32-4.54) were the only risk factors associated with hospitalisation. The risk of ICU admission in the second time period (Time 2) was reduced by 86% (RR = 0.14; 95% CI 0.03-0.71) compared to the first time period (Time 1). The SIR of hospitalisation (SIR 14.51; 95% CI 11.37-17.65) and ICU admission (SIR 14.58; 95% CI 2.91-26.24) showed an increase in the number of events in dialysis patients compared to the general population., Conclusions: Our analysis revealed that while the second variant of the virus increased infection rates, it was concurrently associated with mitigated severity of infections. Dialysis patients exhibited a higher susceptibility to both COVID-19 hospitalisation and ICU admission than the general population throughout the pandemic., (© 2024.

Background: The aim of this study was to evaluate the efficacy and safety of COVID-19 vaccines in patients undergoing haemodialysis in Italy compared to the general population., Methods: In this cohort study, 118 dialysis centres from 18 Italian Regions participated. Individuals older than 16 years on dialysis treatment for at least 3 months, who provided informed consent were included. We collected demographic and clinical information, as well as data on vaccination status, hospitalisations, access to intensive care units and adverse events. We calculated the incidence, hospitalisation, mortality, and fatality rates in the vaccinated dialysis cohort, adjusted for several covariates. The incidence rates of infection in the dialysis cohort and the general population were compared through Standardised Incidence Rate Ratio., Results: The study included 6555 patients vaccinated against SARS-CoV-2 infection according to the schedule recommended in Italy. Between March 2021 and May 2022, there were 1096 cases of SARS-CoV-2 infection, with an incidence rate after completion of the three-dose vaccination cycle of 37.7 cases per 100 person-years. Compared to the general population, we observed a 14% reduction in the risk of infection for patients who received three vaccine doses (Standardised Incidence Rate Ratio: 0.86; 95% Confidence Interval: 0.81-0.91), whereas no statistically significant differences were found for COVID-19-related hospitalisations, intensive care unit admissions or death. No safety signals emerged from the reported adverse events., Conclusions: The vaccination program against SARS-CoV-2 in the haemodialysis population showed an effectiveness and safety profile comparable to that seen in the general population., (© 2023.

The Italian nephrology has a long tradition and experience in the field of dietetic-nutritional therapy (DNT), which is an important component in the conservative management of the patient suffering from a chronic kidney disease, which precedes and integrates the pharmacological therapies. The objectives of DNT include the maintenance of an optimal nutritional status, the prevention and/or correction of signs, symptoms and complications of chronic renal failure and, possibly, the delay in starting of dialysis. The DNT includes modulation of protein intake, adequacy of caloric intake, control of sodium and potassium intake, and reduction of phosphorus intake. For all dietary-nutritional therapies, and in particular those aimed at the patient with chronic renal failure, the problem of patient adherence to the dietetic-nutritional scheme is a key element for the success and safety of the DNT and it can be favored by an interdisciplinary and multi-professional approach of information, education, dietary prescription and follow-up. This consensus document, which defines twenty essential points of the nutritional approach to patients with advanced chronic renal failure, has been written, discussed and shared by the Italian nephrologists together with representatives of dietitians (ANDID) and patients (ANED).

Background: A clinical audit is used to verify the application of evidence-based clinical guidelines. Our regional section of the Italian Society of Nephrology was the first to establish a region-based program of clinical audits of compliance with guidelines for treating osteodystrophy and anemia of patients on chronic dialysis. This study summarizes the main results of the 2 audits of the Piemonte region., Methods: Structured questionnaires were sent twice to all of the 22 dialysis centers of Piemonte and to the Center of Valle D'Aosta for an Audit on Osteodystrophy (in 2000 and 2004) and for the Audit on Anemia (2003). The questionnaires were meant to evaluate the clinical schedule of treatment relative to calcium-phosphate balance and anemia in dialysis patients., Results: All centers responded, showing low levels of agreement with the targets of Italian guidelines. In sum, in 2000 only 27% of centers had more than 70% of patients with serum phosphate <5.5 mg/dL, but that rate had increased to 33% in 2004. Only 35% (in 2000) and 40% (in 2004) of the centers had more than 90% of patients with Kt/V >1.2. The Audit on Anemia showed a median of 42% of patients with hemoglobin between 11 and 12 g/dL, and only 2 centers had more than 70% of patients above this target., Conclusions: The first result of our pioneering experience was that we found that compliance with minimal levels of care was still inadequate, with regard to hyperphosphatemia, dialysis adequacy and anemia. Nevertheless, the 2nd Audit on Osteodystrophy showed a relative improvement in the results. But, most importantly, this open regional report has encouraged comparisons, and motivated centers to adopt a strategy of understanding, addressing and correcting inadequate levels of care, and furthermore increased satisfaction with the care being offered.
