Impact of smoking on kidney transplantation outcomes

Abstract

Aim. To investigate the impact of smoking on kidney transplantation outcomes. Subjects and methods. The materials of 350 patients (including 229 (65.4%) men aged 37.1±0.6 years) who had undergone kidney allotransplantation (KAT) for end-stage renal disease were analyzed. The main outcomes of KAT (patient status (alive or dead); renal allograft (RAG) function or dysfunction; development of chronic transplant nephropathy (CTN)), were studied. Results. There were 52 (14.8%) smoking patients (50 (96.2%) men and 2 (3.8%) women). The survival rate of smokers after KAT was significantly lower (p=0.043), as was the duration of graft function in the smoking patients (p=0.038). There were statistically significant associations of smoking with age, sex, time to normalize post-KAT serum creatinine concentrations, the development of CTN and graft rejection crises, postoperative hypertension, post-KAT serum creatinine, hemoglobin, and albumin levels, pretransplantation alanine aminotransferase concentrations, pre-KAT left ventricular hypertrophy, patient compliance with the prescribed treatment regimen, the presence or absence of a job in the patient after KAT (p
