Resistant and Apparently Resistant Hypertension in Peritoneally Dialyzed Patients.

Hypertension in chronic kidney disease patients is very common. The definition of resistant hypertension in the general population is as follows: uncontrolled blood pressure (BP) on three or more hypotensive agents in adequate doses, or when patients are on four or more hypotensive agent categories irrespective of the BP control, with diuretics included in the therapy. However, these resistant hypertension definitions do not apply to the setting of end-stage kidney disease.

How COVID-19 Outbreak Influenced Transplantation in Poland.

Announced by the World Health Organization in early 2020, the pandemic caused by SARS-CoV-2 infections has had a huge impact on healthcare systems around the world. Local and international authorities focused on implementing procedures to safeguard the health of the population. All regular daily activities were disrupted.

Main Barriers to the Introduction of a Home Haemodialysis Programme in Poland: A Review of the Challenges for Implementation and Criteria for a Successful Programme.

Introduction: Home dialysis in Poland is restricted to the peritoneal dialysis (PD) modality, with the majority of dialysis patients treated using in-centre haemodialysis (ICHD). Home haemodialysis (HHD) is an additional home therapy to PD and provides an attractive alternative to ICHD that combines dialysis with social distancing; eliminates transportation needs; and offers clinical, economic, and quality of life benefits. However, HHD is not currently provided in Poland.

Current Status of Renal Anemia Pharmacotherapy-What Can We Offer Today.

Chronic kidney disease (CKD) is one of the fastest-growing major causes of death internationally. Better treatment of CKD and its complications is crucial to reverse this negative trend. Anemia is a frequent complication of CKD and is associated with unfavorable clinical outcomes.

Amyloidosis: A cancer-derived paraproteinemia and kidney involvement.

Amyloidosis is the general term describing the extracellular tissue deposition of fibrils composed of low molecular weight subunits of a variety of proteins. There are multiple different human protein precursors of amyloid fibrils. Amyloid deposits are stained using Congo Red and show typical apple-green birefringence in polarized microscopy.

[Nephrology complications in cardiology].

Heart disease and renal failure occurring together, constitute a potential threat to life, especially in the elderly. Diseases of the cardiovascular system are the main factor in morbidity and mortality in patients with chronic kidney disease. On the other hand, chronic kidney disease is considered a risk factor for cardiovascular diseases.

[The influence of simvastatin on hsCRP and some paramneters of hemostasis in patients with ischemic heart disease].

Inflammation and disturbances of the hemostatic system may play a role in pathogenesis and complications of ischemic heart disease. More and more reports indicate that apart from their cholesterol-lowering effect statins also exert other beneficial effects in cardiovascular diseases. Taking this into consideration, the aim of the study was to assess the influence of simvastatin (20 mg per day) on a marker of inflammation - CRP and some parameters of coagulation and fibrinolysis in 22 patients with ischaemic heart disease.

Femoral localization and higher ultrafiltration rate but not concentration of heparin used for canal locking of hemodialysis catheter are negative predictors for its malfunction.

Background/aim: Non-tunneled, temporal hemodialysis (HD) catheters are commonly used as short-term vascular access for the HD procedure. One of their late complications is thrombotic occlusion of the catheter ensuing in their malfunction. A heparin lock is conventionally used for maintaining the patency of the catheter.
