Background: Guidelines indicate that a low-protein diet (LPD) delays dialysis in severe chronic kidney disease (CKD). We assessed the value of these guidelines by performing a retrospective analysis in our renal clinical practice.

Methods: The analysis was performed from 1 January 2010 to 31 March 2018 in 299 CKD Stage 4 patients followed for 70 months in collaboration with a skilled nutritionist.

Article Synopsis
  • IgA nephropathy (IgAN) shows a wide range of clinical outcomes, with baseline proteinuria being a key risk factor for progression; however, time-average proteinuria (TAp) during follow-up is identified as a stronger indicator of kidney health and treatment response.
  • *In a study analyzing 325 IgAN patients from 1989 to 2005, findings reveal that lower TAp correlates with improved renal survival, with a notable 16.6% experiencing significant kidney function decline.
  • *Key factors influencing lower TAp and better kidney outcomes include female gender, use of corticosteroids, lower initial protein levels, and blood pressure management, suggesting that a 6-month corticosteroid treatment is effective at improving kidney function

Peritoneal dialysis (PD) has a prevalence in Italy that does not exceed 10% of patients in substitution treatment. Among the barriers, which hinder access to DP, the lack of patient autonomy or family support has great importance. In 2012 in Lombardy, the lack of support has prevented 155 new patients to use DP and has forced 17 to stop it.

In 2009, 90% of nephrology centers in Lombardy declared to have a ''predialysis'' outpatient department, without, however, specifying its meaning. Research carried out in 2008 among nephrology centers in Piemonte showed how ambiguous this term was. According to the 2007 EDTA-ERA Registry, about 68% of European nephrology centers stated that they had an outpatient department for stage 4-5 CKD patients, but no information was available about the role of patients in the choice of dialysis.

Cardiovascular disease is the first cause of morbidity and mortality in dialysis patients. Hyperphosphatemia and elevated serum calcium-phosphate levels have recently been investigated as inducing factors on extraskeletal calcification in this population. In vitro studies demonstrated that human aortic smooth muscle cells calcify when incubated in a high phosphate medium, where calcium and calcitriol are not changed.
