Compliance and satisfaction with treatment as a success of therapy effectiveness in the group of patients with ischemic heart disease: a cross-sectional study.

Objectives: Non-adherence and non-compliance to pharmaceutical treatment is one of the most common causes of not effective management of patients suffering from ischemic heart disease (IHD). It is crucial to understand the reasons behind it but studies on this subject performed in the Polish population are still lacking.

Material And Methods: The 329 patients (160 male and 169 female) diagnosed with IHD who reported for follow-up appointments are examined.

Oxidative stress parameters as biomarkers of bladder cancer development and progression.

The epidemiological studies confirm that the overproduction of free radical is an important factor of cancer induction as well as development, and loss of antioxidant systems efficiency is associated with an increased risk of carcinogenesis. While bladder cancer is the fourth most common type of cancer all over the world, there is little evidence of the advancing changes in oxidative/nitrative stress during the progression of bladder cancer. Our study aimed to investigate the plasma levels of typical markers of oxidative/nitrative stress depending on the clinical classification of bladder cancer differentiation and infiltration degree.

Selected biochemical parameters in the urine of HIV-infected patients in monitoring of kidney function.

Introduction: For years, there has been an increase in the number of cases of chronic kidney disease (CKD) in human immunodeficiency virus (HIV)-infected patients. Renal dysfunction can be caused by direct effects of HIV on the kidneys but also of applied combined antiretroviral therapy (cART). Therefore there is a need of renal function diagnosis to monitor the development of kidney disturbances.

The aim of this study was to assess the significance of heparanase in the pathogenesis of particular glomerulonephritis types.

[The biochemical carcinogenesis of selected heavy metals in bladder cancer].

Bladder cancer takes the second place in the classification of morbidity of urinary system cancers. Many chemical factors take part in cancerogenesis. It is suggested that exposure to heavy metals such as arsenic, chromium, nickel and cadmium as well as its metabolites may trigger the bladder cancer through inducing excessive reactive oxygen species production and oxidative stress formation which are responsible for DNA damage.

[Comorbidities as risk factors of chronic kidney disease in HIV-infected persons].

Significant survival prolongation in HIV-infected patients due to effective antiretroviral therapy is connected with increasing prevalence of chronic non-infective diseases in this population, among them chronic kidney disease. The pathogenesis of kidney disease in the setting of HIV includes conditions specific for HIV infection: direct effect of the virus, stage of immunodeficiency and drug toxicity. Chronic comorbidities, such as diabetes mellitus, hypertension, and hyperlipidemia, are additional significant risk factors of kidney disease.

Preliminary study on application of urine amino acids profiling for monitoring of renal tubular injury using GLC-MS.

Background: The early diagnosis of the nephrotoxic effect of xenobiotics and drugs is still an unsolved problem. Recent studies suggest a correlation between the nephrotoxic activity of xenobiotics and increased concentration of amino acids in urine. The presented study was focused on the application of GLC-MS method for amino acids profiling in human urine as a noninvasive method for monitoring of kidney condition and tubular injury level.

The investigation of specific biochemical markers in monitoring kidney function of drug addicts.

Introduction: An increasingly important issue in the Polish population is drug abuse. It leads to extensive damage of parenchymal organs, including kidney. Establishing early markers of organ damage and their monitoring during rehabilitation therapy is therefore of pivotal importance.

[The diagnostic importance of the new marker KIM-1 in kidney damage].

In recent years, the rapid development of scientific research led to the introduction of strategies based on new markers that allow for estimation of the latent disease period before the clinical symptoms of actual kidney failure are revealed. The experimental tests carried out on animals and cell lines derived from the proximal tubule have made possible the detection of genes that are induced early after hypoxia. The protein products of these genes can be considered as useful markers for the diagnosis of renal failure.

[The potential nephrotoxicity of antiretroviral drugs].

 The intensive studies carried out in many scientific laboratories and the efforts of numerous pharmaceutical companies have led to the development of drugs which are able to effectively inhibit HIV proliferation. At present, a number of antiretroviral agents with different mechanisms of action are available. Unfortunately, long-term use of antiretroviral drugs, however, does not remain indifferent to the patient and can cause significant side effects.

Plasma and urine leukocyte elastase-alpha1protease inhibitor complex as a marker of early and long-term kidney graft function.

Background: Neutrophils are mediators of ischaemia/reperfusion (I/R) injury following kidney transplantation (kTx). Leukocyte elastase (LE) complex with alpha(1)protease inhibitor (LE-alpha(1)PI) is a marker of neutrophil degranulation. The aim of this study was to evaluate LE-alpha(1)PI as a marker of I/R kidney damage and to search for correlations between leukocyte activation and post-transplant complications.

[Chemical substances as risk factors of nephropathy in diabetes mellitus].

Although diabetes mellitus, a metabolic disease, does not fall into the group of diseases induced by toxic substances or environmental pollution, there is much evidence that some chemicals have considerable importance in its development. Exposure to substances with potential renal toxicity is especially dangerous for diabetics because it accelerates and intensifies diabetic nephropathy. This paper discusses the relationship between the xenobiotics and the development of diabetes mellitus and diabetic nephropathy with particular emphasis on those substances that causes the greatest damage to the kidneys.

Kidney graft function in long-term cyclosporine and tacrolimus treatment: comparative study with nephrotoxicity markers.

Calcineurin inhibitors improve kidney allograft survival in the posttransplantation period; however, they may cause nephrotoxicity. The objective of this study was to compare the effect of cyclosporine (CsA) and tacrolimus (Tac) treatment on the transplanted kidney. The study included 219 patients aged 21 to 65 years.

Elastase deposits in the kidney and urinary elastase excretion in patients with glomerulonephritis--evidence for neutrophil involvement in renal injury.

Objective: Elastase is a key proteolytic enzyme released during polymorphonuclear leukocyte degranulation. There are abundant data of elastase involvement in the development of injury in experimental models of glomerulonephritis (GN), but scant direct evidence of its involvement in human primary GN. The aims of this study were to determine the immunolocalization of elastase deposits in kidney biopsy specimens from patients with primary idiopathic GN, to attempt to correlate the distribution and intensity of deposits with urinary elastase excretion, and to determine clinical markers of renal injury in several types of primary idiopathic GN.

Enzymuria and low molecular weight protein excretion as the differentiating marker of complications in the early post kidney transplantation period.

Renal function in the early post-transplantation period depends largely on factors affecting the kidney prior to implantation. Function of the graft may be also disturbed by the most common complications of the early post-operative period such as acute graft rejection (AGR), acute tubular necrosis (ATN) and may be modified by nephrotoxic action of cyclosporine A (CsA). Evaluation of excretion of enzymes and low molecular weight proteins (LMWP) may help in the differentiation of these complications.

Styrene and ethylene glycol have a synergetic effect on lipid peroxidation that is better protected than repaired by CoQ10.

Previous study of a group of 22 workers occupationally exposed to styrene, ethylene glycol and their mixture at a paint and lacquer industry indicated significantly elevated concentration of malondialdehyde with 4-hydroxynonenal (MDA+4-HNE) in the blood plasma, successfully decreased with coenzyme Q10 (CoQ10) supplementation. The aim of present study is to evaluate whether the exposure to styrene or/and ethylene glycol could be responsible for the increase in MDA level. The mechanism of a single solvent action and the mixture was examined, specially whether it is connected with hydroxyl radical (*OH) generation.

Etiology of increased enzymuria in different morphological forms of glomerulonephritis.

Background: High urinary excretion of lysosomal enzymes is thought to reflect tubulointerstitial damage and is observed both in the acute and chronic phases of various morphological forms of glomerulonephritis (GN). It is related to the degree of proteinuria and secondary interstitial inflammatory process. N-acetyl-beta-D-glucosaminidase (NAG) and beta-glucuronidase (beta-GR) are the most commonly used markers of tubulointerstitial injury.
