RESUMO
No clinical trials have specifically explored the benefits of low-protein diet in patients with different stages of chronic kidney disease (CKD) 3B. In the absence of RCTs, expert opinion may be a valid surrogate to estimate treatment effectiveness. A questionnaire-based survey of a large sample of nephrologists from Southern Italy was conducted to explore benefits of low-protein diet (LPD) in delaying dialysis entry in different CKD stages. For the case vignettes describing eight different patient profiles with various CKD stages, nephrologists reported expected benefits as time delay of dialysis entry. Information was collected through questionnaires filled by 88 nephrologists from different Southern Italian hospitals. On average, nephrologists estimated the highest delay in starting dialysis due to LPD in stages 3B (15 months) and 3A (14 months), and the lowest for 5 stage (3 months). According to opinion of a large sample of Southern Italian nephrologists, low-protein diet may be more efficacious if started in CKD stage 3B than 4 and 5.

We performed a cross-sectional study to compare the intake of energy, macronutrients, fiber, sodium and iron and the anthropometric status of infants and toddlers living in North (Milano) and South Italy (Catania). Nutrient intake was evaluated using a 7-day weighed food record. Out of 400 planned children aged 6 to 36 months, 390 (98%) were recruited, 189 in Milano and 201 in Catania. The mean (standard deviation) age was 17 (9) months in Milano and 17 (10) months in Catania. Anthropometry, energy intake and macronutrient intake were similar in Milano and Catania. However, iron intake was 27% lower and fiber intake 16% higher in Milano than in Catania. Despite normal anthropometry and energy intake, in the pooled sample there was a high intake of proteins, simple carbohydrates, saturated fats and sodium, and a low intake of iron and fiber compared to Italian reference values. This is the first study to report the macro- and micro-nutrient intake of children aged <12 months using the 7-day weighed food record and one of the very few studies that have employed such reference method in children from the general population.
