Neoangiogenesis is a basic factor for most physiological as well as pathological processes i.e. tumor metastases. The most important is vascular endothelium growth factor (VEGF) and its receptors (VEGFR1/2) in angiogenesis processes. Nowadays antiangiogenic agents (which inhibit VEGF like bevacizumab neither VEGFR2 like ramucirumab) are widely used in very different chemotherapeutic regimens in clinical oncology. The signalling pathway VEGF-VEGFR plays a crucial role in supporting of adequate kidney function. Appearance of antiangiogenic drugs led to adverse nephrotoxic effects arterial hypertension, proteinuria, rarely nephrotic syndrome, and kidney dysfunction. Various hystological variants of nephropathy are described, however, in most cases, signs of thrombotic microangiopathy of the renal vessels are noted. BODIPY 493/503 clinical trial This literature review discusses mechanisms, clinical and morphological aspects of nephropathy associated with antiangiogenic drugs.Osteoarthritis is a common pathology, which indicates the great medical and social significance of this disease. The article discusses the issues of pathogenesis, risk factors and diagnosis of professional and professionally caused osteoarthritis the age of onset of the disease, the specifics of work, the localization of joint damage. Differential diagnosis issues are discussed.Radiofrequency renal artery denervation (RND) was introduced as a method of interventional treatment of resistant hypertension almost ten years ago. The first studies demonstrated the effectiveness of this procedure. This has led to growing interest in this area and the rapid development of the method. However, the results of the first randomized trial of SYMPLICITY HTN-3 questioned the role of RND in the treatment of resistant hypertension, this fact conducted to the decrease in the recommendation class and level of evidence in the Guidelines of the European Society of Cardiology and the European Society of Hypertension in 2018. To date, the medical community is actively discussing the results of recently published trials such as SPYRAL HTN-OFF MED, SPYRAL HTN-ON MED, RADIANCE-HTN SOLO and RADIOSOUND-HTN.A clinical observation is presented of a patient with pulmonary sarcoidosis, who was diagnosed with kidney damage after three years with the development of chronic renal failure and the need for replacement therapy. A histological examination of the renal biopsy revealed a granulomatous process in the interstitial tissue, which was regarded as an extrapulmonary manifestation of sarcoidosis. Pulse therapy with glucocorticoids was prescribed and an attempt was made to reduce hemodialysis sessions.Atypical hemolytic-uremic syndrome (aHUS) is a chronic systemic disease of a genetic nature, which is based on uncontrolled activation of the alternative complement pathway, leading to generalized thrombosis in the vessels of the microvasculature (complement-mediated thrombotic microangiopathy). To date, therapy with eculizumab is the most effective and pathogenetically substantiated method of treating patients with ASH. Using the example of three clinical cases of patients with a verified diagnosis of aHUS, the high efficiency and safety of the worlds first bioanalogue of eculizumab in the treatment of adult patients with aHUS (complement-mediated thrombotic microangiopathy) was demonstrated.We present a case with a rare variant of glomerulonephritis, IgM nephropathy, which occurs mainly with nephrotic syndrome. The clinical features of this variant of kidney damage are characterized; the pathogenetic and the transformation of this form of nephritis into focal segmental glomerulosclerosis are discussed. The development of severe nephrotic syndrome at the beginning of the disease, the formation of secondary steroid resistance have confirmed this hypothesis and have justified the treatment with cyclosporin A aimed at the recovery of the function of the podocyte with remission of nephritis.
Conducting a pilot study to assess the effect of thermal heliox on the state of the respiratory tract by studying of the exhaled breath condensate protein composition before the thermal heliox procedure, immediately after and after three hours of relaxation Materials and methods. A comparative study of the exhaled breath condensates (EBC) protein composition of five non-smoking healthy donors was carried out. The EBC was taken before the respiratory procedure, immediately after a 20-minute inhalation by mixture of He/O2 gases (70/30) heated to 70C and 3 hours later. The protein composition was determined by chromatography-mass spectrometric analysis after selective tryptic hydrolysis. The results were processed using the Mascot program and the UniProt database.
After the heliox procedure, the volume of the collected condensate (11.5 ml) decreases by an average of 32% and is practically restored after three hours of relaxation. Most proteins were consistent for all samples, regardless of the thermal heliox procedure. These are keratins, several proteins of the immune system (immunoglobulins, compliment proteins), tubulin. In samples after thermal heliox, the appearance of small amounts of additional proteins is observed. These are proteins of muscle metabolism (actin and calmodulin), fibrinogen, traces of hemoglobin, apolipoprotein, type B creatine kinase. After three hours of relaxation, tubulin disappears in the EBC.
Most exhaled proteins are the same before, after the procedure, and for three hours of relaxation. The results obtained demonstrate the relative safety of the use of high temperature heliox as a therapeutic agent.

To evaluate a 12-week course of combined alloturinol-lowering therapy with a prophylactic anti-inflammatory dose of movalis for the frequency of exacerbations and the quality of life of patients with gout.
Allopurinol was administered orally, 1 time per day. Every 3 weeks, the dosage of the drug was increased by 50 mg to 300 mg per day under the control of the level of serum uric acid (sUA). The total daily dose of the drug movalis, used in the form of different dosage forms, was 7.515 mg. The clinical effectiveness of the treatment was evaluated after 3, 6, 9 and 12 weeks according to physical examination, the dynamics of joint pain at rest, during movement and palpation, according to the visual analogue scale (VAS) in millimeters, Likert scale, EuroQol-5D-5L questionnaire, care for oneself, habitual daily activities, the presence of anxiety and depression, assessment of satisfaction with treatment (on a scale of 1 to 5, where 1 is the complete absence of improvement or worsening, and 5 is a very good result); took into account the period of remission, as well as the time before the onset of relapse of gouty arthritis.
