In one RCT in which people with type 1 and type 2 diabetes and nephropathy were combined (N=80) generic 20 mg prednisone overnight delivery gluten allergy symptoms joint pain, there were NS differences in GFR decline between those randomised to LPD compared with a UPD generic prednisone 10 mg online allergy symptoms brain fog. Extraction of data from a trial included in the meta-analysis showed that there were NS differences between LPD group 98 8 Self management (N=41) and UPD (N=41) for changes in mid arm circumference in people with type 1 diabetes and nephropathy.

The GDG recognised the importance of dietary advice in the management of hyperkalaemia, hyperphosphataemia and salt and water intake for people with advanced CKD. The GDG agreed that people with advanced CKD and hyperkalaemia, hyperphosphataemia or salt/water overload therefore need advice from an appropriately trained professional. In this context, advanced CKD will usually be people in stage 4 and 5 and generally those with an eGFR <20 ml/min/1. It was noted that apart from the risks of malnutrition, low protein diets are usually unpalatable and are time consuming to adhere to as all portions must be weighed. These aspects are likely to affect the quality of life of people with CKD and therefore any recommendations about dietary restriction must have a sound evidence base. The GDG also noted that adequate iron in the diet is important in CKD and restricting protein intake may adversely influence iron intake. The GDG agreed that the studies combined in the meta-analysis by Pedrini et al. It was also noted that some of the studies were carried out at a time when the pharmacological management, particularly the use of ACE inhibitors, was likely to be different. The individual studies were examined and the GDG agreed that there was limited evidence that there may be a benefit of protein restriction in patients with stage 4 and 5 CKD, but the evidence did not point to an optimal protein intake. R37 Where dietary intervention is agreed this should occur within the context of education, detailed dietary assessment and supervision to ensure malnutrition is prevented. R38 Offer dietary advice to people with progressive CKD concerning potassium, phosphate, protein, calorie and salt intake when indicated. The optimal treatment target remains poorly defined and considerable confusion has occurred because there is a lack of conformity between recommended treatment targets in different disease guidelines and in the Quality and Outcomes Framework. The objective of this section was both to consider the evidence and to rationalise treatment targets with those recommended by the NICE guidelines for management of type 2 diabetes and hypertension. Although the hypertension guideline did not recommend home monitoring recent data shows that self-measurement leads to less medication use than clinic blood pressure measurement without leading to significant differences in outpatient values of blood pressure. Antihypertensive therapy should be adjusted to achieve blood pressure <130/80, or <125/75 mmHg for those with a PCR >100 mg/mmol. The Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines35 recommend achieving blood pressure <130/80 mmHg and the SIGN guidelines32 recommend a target maximum systolic blood pressure of 130 mmHg in those with 1 g/day of proteinuria. CARI guidelines are more proscriptive, recommending a target blood pressure of <125/75 mmHg in those with proteinuria >1 g/day but acknowledging that the precise goal below 130/80 mmHg is not clear. The British Hypertension Society guidelines define optimal blood pressure control in people with kidney disease as <130/80 mmHg and suggest reducing blood pressure to <125/75 mmHg in those with proteinuria ≥1 g/24 h. All post-hoc analyses of RCTs were downgraded to level two evidence. A case series (N=860, follow-up 10 years) investigated the association of systolic blood pressures <133 mmHg and mortality in a cohort of men (mean age 68±10 years) with stages 3 to 5 CKD. Two post-hoc analyses of the Irbesartan in Diabetic Nephropathy Trial (IDNT) RCT (N=1590, median follow-up 2. Diastolic blood pressure was not significantly associated with all-cause mortality, cardiovascular mortality, or congestive heart failure. There was a significantly higher risk of cardiovascular mortality for people with an achieved SBP <120 mmHg compared with SBP >120 mmHg. People with an achieved SBP ≤120 mmHg had a significantly greater risk of congestive heart failure compared to people with an achieved SBP >120 mmHg. For people with baseline urinary protein excretion >3 g/day (N=32), there was a benefit of intense control (GFR decline 5.
