ABSTRACT
BACKGROUND: Few reports have addressed the change in renal replacement therapy (RRT) management in the Intensive care Units (ICUs) over the years in western countries. This study aims to assess the trend of dialytic practice in a 4.5-million population-based study of the northwest of Italy. METHODS: A nine-year survey covering all the RRT provided in the ICUs. Consultant nephrologists of the 26 Nephrology and Dialysis centers reported their activities in the years 2007, 2009, 2012, and 2015. RESULTS: From 2007 to 2015 the patients treated increased from 1042 to 1139, and the incidence of RRT from 254 to 263 cases/10^6 inhabitants. The workload for dialysis center was higher in the larger hub hospitals. RRT for acute kidney injury (AKI), continuation of treatment in chronically dialyzed patients, or extrarenal indications accounted for about the stable rate of 70, 25 and 5% of all RRT sessions, respectively. Continuous modality days increased from 2731 days (39.5%) in 2007 to 5076 (70.6%) in 2015, when the continuous+prolonged treatment days were 6880/7196 (95.6% of total days). As to RRT timing, in 2015 only the classical clinical criteria, and no K-DIGO stage were adopted by most Centers. As to RRT interruption, in 2015 urine volume was the first criterion. Implementation of citrate anticoagulation (RCA) for RRT patients significantly increased from 2.8% in 2007 to 30.9% in 2015, when it was applied in all 26 Centers. CONCLUSIONS: From 2007 to 2015, current practice has changed towards shared protocols, with increasing continuous modality and RCA implementation.

BACKGROUND: Pregnancy in CKD is an increasing challenge, considering also the paucity of therapeutic tools available in pregnant women. While theoretically interesting, the experience with low protein diets in pregnancy is limited. Aim of this feasibility study is to review our experience with supplemented vegetarian low protein diets in pregnancy, as a "rescue treatment" for severe CKD and/or proteinuria. METHODS: Data were gathered prospectively. Diet schema: proteins: 0.6-0.7 g/Kg/day, amino and chetoacid supplementation, 1-3 free meals/week. Compliance, side effects, biochemical data recorded at each visit (at least twice monthly). RESULTS: Between January 2000 and February 2010, out of 168 pregnancies referred, 12 were managed by the diet (11 patients; median age 33, range 20-38). One pregnancy was terminated (patient's choice); the other 10 patients delivered 11 healthy babies. At referral, 2 patients were in stage 4 CKD, 4 in stage 3, 4 had nephrotic proteinuria (3.6-6.3 g/day). One patient doubled serum creatinine; none needed renal replacement therapy within 6 months from delivery. No patient complained of side effects, nor developed hyperkalemia or hypercalcaemia. Two babies from mothers in CKD stage 4 were small for gestational age; 9/11 were delivered by caesarean section (median gestational age 33 weeks: range 28-37; birth weight 935-2620 g) within a policy of delivery in the presence of foetal growth impairment and/or worsening of proteinuria, GFR, hypertension or foetal conditions. All babies are well, 1 month, 7.5 years from delivery. CONCLUSION: Our report suggests considering vegetarian diets as an additional tool in the management of pregnant CKD patients.
