ABSTRACT Objective: to investigate the characteristics of the clinical course of community-acquired pneumonia in patients with constant kidney infection. The ponder included 120 patients with pneumonia: 40 patients had no history of renal pathology (group M), 80 patients endured from inveterate kidney infection (GFR for 3 months some time recently the improvement of pneumonia 30-60 ml / min / 1.7 m2, group M + CKD ). Confirmation of the determination was carried out on the premise of chest X-ray, the detailing of the conclusion included deciding the sort of pneumonia - croupous or central intersecting. In a comparative evaluation of the X-ray picture within the explored groups, it was famous that in patients with pneumonia against the foundation of CKD, lobar and central intersecting pneumonia with a huge penetrate volume were altogether more frequent (p <0.001). Within the flow of follow-up, the larger part of patients (78 out of 120 patients, 65%) appeared positive clinical and radiological elements, 20 patients (16.67%) appeared no critical elements, and 22 patients (18.33%) had clinical and radiological elements. negative. Negative clinical and radiological flow was more frequently watched within the group of patients in whom pneumonia developed against the background of CKD (p <0.01).
