Takayasu arteritis belongs to the group of systemic vasculitis with a predominant lesion of large - caliber vessels and the development of stenosis of their lumen. In world practice, to establish the diagnosis of arteritis Takayasu apply the criteria proposed by the American College of rheumatologists. Currently, there are no randomized clinical trials related to the disease, and the diagnosis and treatment of patients are based on a number of small studies, a series of clinical cases and expert opinion. The described clinical observation of a patient with Takayasu arteritis is of interest in connection with the detected atrial myocarditis during MRI diagnosis of the heart with contrast, which allows us to discuss the feasibility of this imaging technique in complex and doubtful cases.

Chronic kidney disease (CKD) is a supra - nosological term that reflects the progressive nature of chronic kidney diseases, which are based on the mechanisms of nephrosclerosis. Diagnosis of CKD at the earliest stages is of great importance, because it allows, by using therapeutic agents, to slow the progression of renal dysfunction and the development of cardiovascular complications. However, the currently available methods for diagnosing renal function impairment, including the determination of endogenous creatinine clearance, can detect renal dysfunction too late, when around 40-50% of the renal parenchyma is already reversibly or irreversibly damaged. ⋯ In particular, it has been shown that their expression profile in blood or urine can reflect changes in cells involved in a particular pathological process, since these cells can secrete a specific population of microRNAs, for example, through secretion of microRNA-containing exosomes. This gave grounds for considering increased or decreased expression of individual microRNAs in renal tissue or biological fluids (including urine) as new biomarkers for the diagnosis and monitoring of CKD. This review presents the results of recent experimental and clinical studies on these issues.

To determine the frequency, clinical and morphological features of a nephropathy with C1q deposits in chronic glomerulonephritis adult patients. ⋯ Deposits of C1q in kidney were revealed in 4.05% of biopsy specimens in CGN. The most frequent morphological form was the membranous nephropathy. The clinical course was characterized by a nephrotic syndrome, more than at a half of patients - with renal dysfunction.

It has been established that an increased fibroblast growth factor (FGF-23) serum levels significantly contribute to the heart and blood vessels remodeling in patients with chronic kidney disease (CKD). But the precise mechanisms of the FGF-23 cardiac effect are currently being actively studied. At the same time, it is believed that the cardiac effects of FGF-23 may be due to the increasing deficit of Klotho protein as CKD progresses. In parallel with these changes, a number of studies indicate the persistence of the detectable troponins serum levels in CKD patients, even in the absence of clear clinical manifestations of cardiovascular diseases (CVD). The aim of the study was to confirm / exclude the existence of a causal relationship between elevated FGF-23, reduced Klotho and elevated troponin-I (as the most specific troponin in CKD). ⋯ The changes in serum levels of FGF-23, Klotho and troponin-I (Tr-I) depended on the stage of CKD. The following correlations were identified: FGF-23 and: Tr-I (r=0.601; p.
