| Popis: | The course of juvenile idiopathic arthritis (JIA) is associated with a long-term infl ammatory process and the use of nonsteroidal anti-infl ammatory drugs (NSAIDs), which can cause nephrotoxicity with fi brotic kidney damage in patients with JIA. Regardless of the etiology of joint damage, prolonged infl ammation promotes the progression of fi brosis, and renal fi brosis is the fi nal common stage of chronic kidney disease (CKD). Kidney biopsy, which is invasive, risky and underutilized, is generally considered the only clinical method to detect fi brosis. Over the past decade, some progress has been made in the search for minimally invasive biomarkers of early kidney fi brosis, with transforming growth factor-β1 (TGF-β1) playing a key role in the progression of kidney fi brosis, but the signifi cance of TGF-β1 in children with JIA is unknown. Material and Methods: 80 children with JIA were examined. Urinary TGF-β1 levels were determined using a TGF-β1 ELISA kit (DRG International, Inc., Germany, EIA-1864) according to the manufacturer’s instructions. Methods of variation statistics were used. Informed consent was obtained from all patients. The study has a positive conclusion of the Commission on Biomedical Ethics of Dnipro State Medical University (Minutes of the meeting of the Commission No. 12 dated December 19, 2002), which decided that the scientifi c research can be considered in accordance with generally accepted moral standards, the requirements of respecting the rights, interests and personal dignity of study participants, bioethical standards for work with pediatric patients. There is no risk to the research subjects in the performance of the work. The legal representatives of the children involved in the research are informed about all aspects related to the purpose, objectives, methods and expected benefi ts of the research. Laboratory and instrumental research methods are generally accepted; the drugs to be used are approved for use. No human experiments were performed. Methods of variation statistics were used. Statistical analysis was performed using the STATISTICA 6.1 software package (StatSoft Inc., serial no. AGAR909E415822FA). The work was carried out as part of the research work of the Department of Propaedeutic of Childhood Diseases and Pediatrics 2 of the Dnipro State Medical University «Development of criteria for early diagnosis and prediction of comorbid kidney damage in children with somatic and infectious diseases» (state registration No. 0119U100932, implementation period 01.2019-12.2023). Results. The mean TGF-β1 level in our study was 20.26±16.34 (14.02, 12.5-17.98) pg/ml. Polyarthritis almost quadrupled the probability of pathological changes in TGF-β1. The overwhelming majority of children with elevated TGF-β1 suff ered from polyarthritis (80.0 %) – one and a half times more often than those with relatively normal TGF-β1 concentration, p0.05). The direct dependence of elevated urinary TGF-β1 levels on clinical features such as polyarthritis and the duration of the active phase of JIA has been demonstrated. These clinical features in children with JIA can be considered as risk factors for the development of early renal fi brosis. Against the background of elevated TGF-β1, a reduced GFR according to the Hoek formula ( |
