The current issue of “Postępy Nauk Medycznych” (“Progress in Medicine”) is a result of the cooperation between centers from Białystok, Warsaw and Zabrze. The published papers are connected with the main topic, i.e. with diabetes and diabetic nephropathy. I will not comment the review papers because of shortage of place, however I would like to recommend these papers to the Reader, hoping that the information included will be helpful in a daily practice.

In this issue there are 5 original papers. In the first one a group of authors from the Medical University of Białystok assessed renal function in the patients with diabetes referred to a coronary artery intervention (1). It is an important problem, as risk of the adverse events after intervention is increasing parallel to a declining renal function. As it was shown, an impaired renal function can be diagnosed in almost half of the patients. The authors conclude that assessing of creatininemia is insufficient for a proper workup, and estimation of glomerular filtration (GFR) is necessary.

The next paper regarding the similar “cardiodiabetonephrologic” group of patients, assessed the influence of pacemaker implantation on the renal function (2). The results indicate that this procedure is safe in patients with as well as without diabetes.
