Tacrolimus: Influence of the Posttransplant Concentration/Dose Ratio on Kidney Graft Function in a Two-Year Follow-Up.

Introduction: Tacrolimus (TAC) metabolism rate has the potential to impact graft function after kidney transplantation (KTx). We aimed to analyze the relationship between the early post-KTx TAC C/D ratio (blood trough concentration normalized by total daily dose) and kidney graft function in a 2-year follow-up.

Methods: We retrospectively analyzed data from 101 post-KTx patients at 3, 6, 12, and 24 months after KTx to identify the C/D ratio cutoff value optimal for dividing patients into fast and slow TAC metabolizers.

The variant allele of the rs188140481 polymorphism confers a moderate increase in the risk of prostate cancer in Polish men.

A number of single nucleotide polymorphisms (SNPs) in the human genome have been associated with increased risk of prostate cancer. Recently, a single SNP in the region of chromosome 8q24 (rs188140481) has been associated with a three-fold increased risk of prostate cancer in Europe and North America. To establish whether rs188140481 is associated with the risk of prostate cancer in Poland, we genotyped 3467 men with prostate cancer and 1958 controls.

[Kidney transplants from donors burdened metabolic acidosis in the course of poisoning with methanol and carbon monoxide].

The question of obtaining organs from donors who died of methanol poisoning has been discussed in the medical literature for many years. The results of such transplants published so far are very optimistic. However, the possibility of permanent and significant injury to transplanted organs caused by poisons or its metabolites raises serious concerns regarding the procedure.

The presence of prostate cancer at biopsy is predicted by a number of genetic variants.

Several single nucleotide polymorphisms (SNPs) have been associated with an elevated risk of prostate cancer risk. It is not established if they are useful in predicting the presence of prostate cancer at biopsy or if they can be used to define a low-risk group of men. In this study, 4,548 men underwent a prostate biopsy because of an elevated prostate specific antigen (PSA; ≥4 ng/mL) or an abnormal digital rectal examination (DRE).

The G84E mutation in the HOXB13 gene is associated with an increased risk of prostate cancer in Poland.

Background: The G84E mutation in the HOXB13 gene has been associated with a high lifetime risk of prostate cancer in North America (about 20-fold). The geographical and ethnic extent of this recurrent allele has not yet been determined.

Methods: We assayed for the presence of the G84E mutation in 3,515 prostate cancer patients and 2,604 controls from Poland and estimated the odds ratio for prostate cancer associated with the allele.

The correlation between zinc and insulin-like growth factor 1 (IGF-1), its binding protein (IGFBP-3) and prostate-specific antigen (PSA) in prostate cancer.

Background: The objective of the present study is to explore the association between zinc concentrations and insulin-like growth factor 1 (IGF-1), its binding protein (IGFBP-3) and total prostate-specific antigen (tPSA) levels in the serum of patients with prostate cancer (PCa) and prostate intraepithelial neoplasia (PIN), a pre-cancer state matched for age.

Methods: The study was carried out in a group of 229 patients who had transurethral prostate biopsy performed. The patients were divided into three groups: control group (BPH), PIN group or PCa group.

[Blood serum osteocalcin and beta-crosslaps concentrations in patients after renal transplantation].

In 16 patients (7 males, 9 females), aged 47.2 +/- 15.9 years, blood serum concentrations of osteocalcin, beta-crosslaps, parathormone, calcium, phosphate, creatinine and urea were determined before renal transplantation and 3 and 6 months following the procedure.

NT-proBNP plasma levels and echocardiographic assessment of cardiac function in patients after renal transplantation.

Background: Cardiovascular diseases are the most important causes of death in patients with chronic renal disease (CRD). Successful renal transplantation (RTx) corrects water and electrolyte disturbances and decreases or eliminates anaemia. It favourably influences cardiac haemodynamics and reduces risk of cardiovascular events.

P53 mutations in urinary bladder cancer patients from Central Poland.

The present study aimed at detection of P53 gene mutations in cells of urinary bladder neoplasms, as the mutations may be regarded as an independent prognostic factor for progression and recurrence of tumours. In the study, 82 patients with clinically diagnosed urinary bladder tumour were included. The control was composed of DNA samples from urine and blood of 202 healthy patients.

Application of multiplex FISH, CGH and MSSCP techniques for cytogenetic and molecular analysis of transitional cell carcinoma (TCC) cells in voided urine specimens.

Multiplex FISH (UroVysion), Comparative Genomic Hybridization (CGH), and Multitemperature Single-Strand Conformation Polymorphism (MSSCP) were applied for non-invasive diagnosis and prognosis of bladder cancer. The UroVysion test was positive in 80% of patients with pT1 and in 100% of patients with either pT2 or pT3 tumours. Tumours with pT3T4 stages were characterized by high numbers of chromosomal imbalances, detected by CGH.
