Chronic kidney disease (CKD) is characterized by poor outcomes, an increasing frequency of new cases, the need for expensive method of renal replacement therapy at the terminal stage. The main task facing the doctor is slowing the progression of CKD and delay the start of dialysis by applying the nephroprotective strategy, of which diet therapy is an essential part. ⋯ With the progression of CKD, the main objectives of the diet therapy are the prevention/correction of complications: protein-energy waisting, metabolic acidosis, ensuring sufficient calories, corresponding to the bodys energy expenditures (3035 kcal/kg of body weight per day), limiting phosphate intake to 0.81 g a day, restriction of food potassium. Low-protein diet in combination with ketoanalogues of amino acids, regular monitoring and correction of the nutritional status of patients at the pre-dialysis stages of CKD is an effective and safe method of nephroprotection, which allows delaying the start of dialysis.

This review devoted to the nephrotic syndrome (NS) subsequent thrombotic outcomes. The pathogenesis of hypercoagulation disorders that cause venous and arterial vascular system thrombosis are studied. Discussed procoagulant and anticoagulant mechanisms imbalance due to the anticoagulants natural urinal loss, affected by disfunction of the glomerular filter selective permeability, leading to high molecular weight liver-derived proteins (at least of the albumin size) leakage, fibrinolysis depression, excessive liver synthesis of plasma clotting cascade factors and platelet activation. ⋯ The most frequent adverse variants of arterial and venous thromboses are studied, specified their basic and general risk factors, as well as individual, varying in different patients. Indications and prophylactic anticoagulant therapy regimen and thrombosis treatment duration in patients with NS are discussed. It also stressed that the decision on time and method of anticoagulant therapy for a NS patients is still a challenge for healthcare providers.

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. ⋯ 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. This literature review discusses mechanisms, clinical and morphological aspects of nephropathy associated with antiangiogenic drugs.

Cardiovascular calcification (CVC) makes a significant contribution to the manifestation of cardiovascular complications in patients with chronic kidney disease. Early CVC markers are currently being actively studied to optimize cardio-renoprotective strategies. We performed a prospective comparative analysis of the following factors: FGF-23, a-Klotho, sclecrostin, phosphate, parathyroid hormone, the estimated glomerular filtration rate (eGFR), central systolic pressure as an independent determinant of CVC.

An evaluation of the effectiveness of immunosuppressive therapy (IST) and tonsillectomy (TE) in patients with IgA nephropathy (IgAN). ⋯ IST was associated with a lower risk of IgAN progression and increased probability of remission, while these effects of IST were limited to patients with proteinuria 2 g/24 h. TE in combination with IST is associated with an additional reduction in the risk of disease progression.
