Nephrotic syndrome (NS) is characterized by high proteinuria (over 3,5g/24 hrs), hypalbuminaemia, general edemas and hypercoagulation. Beside of primary glomerulonephritides this is found in secundary glomerulopaties eg. diabetes, systemic inflammatory diseases, oncology, damage by drugs and poisoning, by alergy, serious infections and in children from hereditary reasons.

Methods: SARS-CoV-2 IgG antibodies against the viral spike protein were measured at baseline and at 8 and 26 weeks after the second vaccine dose.
Background: Patients with inflammatory bowel disease (IBD) on immune-modifying treatment could be at an increased risk for severe coronavirus disease 2019 (COVID-19); thus, data on the efficacy and safety of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccines are essential. We conducted a prospective study of IBD patients vaccinated with BNT162b2, CX-024414, and ChAdOx1 nCoV-19 vaccines. The aim was to evaluate the rate and magnitude of seroconversion, assess the effect of different immune-modifying treatment modalities on the magnitude of anti-SARS-CoV-2 IgG antibody levels, and analyze the impact of anti-SARS-CoV-2 vaccination on the inflammatory biomarkers of IBD.

One of the possibilities to improve postoperative outcomes and recovery in elderly patients is to perform common surgical procedures in the regime of one-day surgery. We compared elderly patients who underwent surgery in a large university hospital with elderly patients who underwent surgery in a facility dedicated to one-day surgery.

Management of elderly patients examination before surgery is routinely organized by general practitioners and internists with an aim to facilitate the surgery team work; to help anesthesiologists focus mainly on strategy of anesthesia (without any other special examination) and surgeons to realize/accomplish effective and save surgery, including elective surgery procedures. Key issue is to summarize the level of risk for surgery and compare it to prediction of follow-up with respect of mortality and morbidity as well as function status after surgery.

This study hypothesizes that being either underweight or obese is associated with a higher hospitalization rate.

Despide of developments in dialysis technology and kidney transplantation there is a growing number of old patients who are not suitable for these methods. Recently were published data showing long-term effect of protein restricted diet supplemented with keto amino acids in elderly.
View Article and Find Full Text PDFBackground: Low protein diets (LPD) have long been prescribed to chronic kidney disease patients with the goals of improving metabolic abnormalities and postpone the start of maintenance dialysis.
Methods: We reviewed the recent literature addressing low protein diets supplemented with ketoacids/essential aminoacids prescribed during chronic kidney disease and their effects on metabolic, nutritional and renal parameters since 2013.
Results: We show new information on how to improve adherence to these diets, on metabolic improvement and delay of the dialysis needs, and preliminary data in chronic kidney disease associated pregnancy.
Tubular transport of sodium (TNa+) and chloride (TCl-) is decreased in patients with chronic kidney disease. The decrease of TCl- is relatively lower than that of TNa+. These changes of tubular transport of Na+ and Cl- participate on the development of acid base disturbance in patients with chronic kidney disease and with their glomerular filtration rate lower than 0.

In this study, we tested the hypothesis that elevated ADMA and decreased EPC can be positively influenced with regular physical exercise early after Tx. Blood samples for analysis of ADMA and EPC were obtained from randomly selected 64 patients after Tx who agreed to participate in a supervised aerobic exercise program for 6 months (group I).

The present paper investigates the relationship between GFR values determined using renal inulin clearance (Cin) and those estimated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula. Our study was performed in 287 potential kidney donors with a mean age of 48 ± 10 years.

Methods: Blood samples before and after six months were obtained from 116 transplant patients participating in an aerobic exercise (Group I). A control group consisted of 122 matched transplant patients who did not exercise regularly (Group II).

Background: Visfatin is a newly recognized adipocytokine produced mainly in visceral fat tissue. Beside its effect on insulin receptor, it serves as proinflammatory cytokine and its level can be changed during inflammatory processes. The aim of the study was to analyze dynamics of serum visfatine level in early period after abdominal surgery and compare it with other proinflammatory markers.

Short-term weight gains and losses are also related to lower and higher mortality risk, respectively. The implications of weight gain or loss may, however, differ between obese individuals and their nonobese counterparts.

Here, we determined the association between the use of single and combined phosphate-binding agents and survival in 6797 patients of the COSMOS study: a 3-year follow-up, multicenter, open-cohort, observational prospective study carried out in 227 dialysis centers from 20 European countries. Patient phosphate-binding agent prescriptions (time-varying) and the case-mix-adjusted facility percentage of phosphate-binding agent prescriptions (instrumental variable) were used as predictors of the relative all-cause and cardiovascular mortality using Cox proportional hazard regression models.

Background: Chronic kidney disease-mineral and bone disorders (CKD-MBD) are important complications of CKD5D patients that are associated with mortality.
Methods: COSMOS is a multicentre, open cohort, prospective, observational 3-year study carried out in haemodialysis patients from 20 European countries during 2005-07. The present article describes the main characteristics of the European dialysis population, the current practice for the prevention, diagnosis and treatment of secondary hyperparathyroidism and the differences across different European regions.
Chronic kidney disease (CKD) is increasingly common, and there is an increasing awareness that every strategy should be used to avoid complications of CKD. Restriction of dietary protein intake has been a relevant part of the management of CKD for more than 100 years, but even today, the principal goal of protein-restricted regimens is to decrease the accumulation of nitrogen waste products, hydrogen ions, phosphates, and inorganic ions while maintaining an adequate nutritional status to avoid secondary problems such as metabolic acidosis, bone disease, and insulin resistance, as well as proteinuria and deterioration of renal function. This supplement focuses on recent experimental and clinical findings related to an optimized dietary management of predialysis, dialysis, and transplanted patients as an important aspect of patient care.
