Clinical Practice Guideline on management of patients with diabetes and chronic kidney disease stage 3b or higher (eGFR <45 mL/min)

Diabetes mellitus is becoming increasingly prevalent and is considered a rapidly growing concern for healthcare systems. Besides the cardiovascular complications, diabetes mellitus is associated with chronic kidney disease (CKD). CKD in patients with diabetes can be caused by true diabetic nephropathy, but can also be caused indirectly by diabetes, e.g. due to polyneuropathic bladder dysfunction, increased incidence of relapsing urinary tract infections or macrovascular angiopathy. However, many patients who develop CKD due to a cause other than diabetes will develop ormay already have diabetes mellitus. Finally, many drugs that are used for management of CKDs, e.g. corticosteroids or calcineurin inhibitors, can cause diabetes. Despite the strong interplay between diabetes and CKD, the management of patients with diabetes and CKD stage 3b or higher (eGFR <45 mL/min) remains problematic. Many guidance-providing documents have been produced on the management of patients with diabetes to prevent or delay the progression to CKD, mostly defined as the presence of microand macro-albuminuria. However, none of these documents specifically deal with the management of patients with CKD stage 3b or higher (eGFR <45 mL/min). There is a paucity of well-designed, prospective studies in this population, as many studies exclude either patients with diabetes, or with CKD stage 3b or higher (eGFR <45 mL/min), or both. This limits the evidence base to these approaches. In addition, due to some new developments in this area, the advisory board of ERBP decided that a guideline on the management of patients with diabetes and CKD stage 3b or higher (eGFR <45 mL/min) was needed and timely:
