To investigate an influence of the currently changed etiologic structure of AA-amyloidosis on the diagnosis and treatment tactics. ⋯ Among the most common causes of AA-amyloidosis at the present stage, in addition to RA (40.3%), a significant place is occupied by a group of diseases with a predominantly autoinflammatory mechanism (53.73%). To confirm the autoinflammatory mechanism of the predisposing disease it is recommended to study a highly sensitive parameter serum protein S100A12. An effective marker of the risk of AA-amyloidosis progression, especially in patients with subclinical activity of inflammatory disease, is a high level of production of amyloidogenic protein-a precursor of SAA.

Chronic kidney disease (CKD) is characterized by high mortality from cardiovascular diseases, the development of which is facilitated by traditional risk factors (typical for the general population) and by nontraditional ones (specific to patients with CKD) as well. These factors include also uremic toxins, for which a causal relationship has been established with specific pathological processes in patients with CKD, comprising the development of vascular dysfunction and accelerated progression of atherosclerosis. Urea has long been considered not as a uremic toxin, but as a marker of metabolic imbalance or dialysis efficiency (Kt/V) in CKD patients. ⋯ Carbamylation of proteins in CKD patients is associated with the development of renal fibrosis, atherosclerosis and anemia. Thus, urea is now regarded as an important negative agent in the pathogenesis of complications in CKD. Studies on a low-protein diet with using ketoanalogues of essential amino acids to minimize the accumulation of urea and other uremic toxins demonstrate the clinical benefit of such an intervention in slowing the progression of CKD and the development of cardiovascular complications.

To assess the diagnostic value of the detection of soluble transferrin receptors (sTfR) and ferritin index (sTfR/log Fer) in patients with spondyloarthritis (SpA) and anemia for the revealing absolute iron deficiency (ID). ⋯ In patients with SpA having CDA/IDA, sTfR and sTfR/log Fer are statistically significantly increased. The results obtained indicate the possibility of diagnosing ID by using these parameters.

The novel coronavirus infection COVID-19 (SARS-CoV-2) is now known to cause a variety of extrapulmonary complications, including cardiovascular, neurological and dermatological complications, many of which occur or last several weeks after infection. We present a clinical case of a patient who first developed symptoms of ankylosing spondylitis 2 weeks after recovering from COVID-19. The patient was prescribed therapy in accordance with international and Russian recommendations for the management of patients with ankylosing spondylitis with a positive effect in the form of absence arthritis, enthesitis and reducing the inflammatory back pain.

To evaluate the cardiovascular risk (CVR) and analyze its relationship with detection of early carotid artery atherosclerotic lesion in patients with rheumatoid arthritis (RA). ⋯ RRS, mSCORE, ASSIGN, QRISK3 calculators equally predict atherosclerotic carotid artery damage in RA patients. The optimal ratio of specificity and sensitivity is shown for the mSCORE scale. Stratification of CVR in RA patients should include assessment of the carotid intima-media thickness. To identify CVR in RA patients, the most informative methods are mSCORE calculation and carotid intima-media thickness determination.
