[Simultaneous living donor pancreas-kidney transplantation in a patient with type 1 diabetes mellitus after program hemodialysis. Case report].

Simultaneous pancreas-kidney transplantation is an effective treatment option for end-stage renal disease with diabetes mellitus. Successful simultaneous pancreas-kidney transplantation allows achieving euglycemia, stabilizing existing microvascular complications and slowing their progression, improving the patient's quality of life, lipid and calcium-phosphorus metabolism, reducing the risks of cardiovascular events. Therefore, in view of the patient's severe general condition due to prolonged intoxication, hyperglycemia and other complications of chronic kidney disease, the earliest possible surgical treatment with minimization of the patient's stay on dialysis therapy is crucial to improve the outcome of transplantation.

[Effect of components of the renin-angiotensin system, rs2106809 polymorphism of the gene, and therapy with RAS blockers on the severity of COVID-19].

Background: Angiotensin-converting enzyme 2 (ACE2) is a key component of the renin-angiotensin system (RAS), providing counter-regulation of its effects and, simultaneously, a receptor for the SARS-CoV-2 entering. It is suggested that factors regulating the balance of the major components of RAS, including ACE2 gene polymorphism, therapy with RAS blockers (ACE inhibitors and angiotensin receptor blockers) - may affect the severity of COVID-19.

Aim: The aim of the study was to investigate the effect of RAS components, the relationship of ACE2 gene polymorphism rs2106809 and ACEi/ARBs therapy with the COVID-19 severity.

[Advanced glycation end products and oxidative stress as a basis for metabolic abnormalities in patients with type 1 diabetes after successful simultaneous pancreas-kidney transplantation].

Aim: To compare advanced glycation end-products (AGE, RAGE) and 3-nitrotyrosine (3-HT) in patients with DM 1 after successful simultaneous pancreas-kidney transplantation (SPK) and kidney transplantation alone (KTA). To assess relationship between levels of AGE, RAGE, 3-HT and renal transplant (RT) function, carbohydrate and mineral metabolism.

Materials And Methods: The study included 58 patients who received kidney transplantation in end-stage renal disease (ESRD).

[Preparation of the dialysis patient with type 1 diabetes mellitus for kidney transplantation].

Kidney transplantation is unique method of renal replacement therapy, allowing to improve quality and duration of life for patients with diabetes mellitus type 1 (DM1) and end-stage renal disease (ESRD) on dialysis therapy. Recently using of innovation technologies for diabetes management and modern immunosuppression enable achieving better results of posttransplant rehabilitation for patients with DM1, especially if kidney transplantation is performed early after initiation of dialysis. Detailed examination of patient with DM1 before potential kidney transplantation is very important to reduce of early and late postoperative complications.

[The analysis of association between type 2 diabetes and polymorphic markers in the CDKAL1 gene and in the HHEX/IDE locus].

The increase in diabetes was noted at the turn of the 21st century. Patients with type 2 diabetes (T2DM) make up the majority of patients. Diabetes is a multifactorial disease.
