Chronic kidney disease (CKD), with or without dialysis, often prompt biochemical tests for pheochromocytoma diagnosis due to high blood pressure, hemodynamic instability or association with certain genetic syndromes. Our objective was to assess plasma free metanephrine and normetanephrine in CKD disease patients, with or without dialysis.Methods: Plasma free metanephrine and normetanephrine were measured by an enzyme-linked immunosorbent assay in 42 pati...

The relationship between the level of genetic variation in CYP17, PSA genes and prostate cancer has been extensively studied but the results are still unclear. A 450c17a (CYP17) polymorphism A1/A2 was described to be significantly associated to prostate cancer. A SNP in the promotor PSA gene is an A to G substitution at position −158 (G158A) was proposed to interact differently with AR, thereby modifying the expression pattern and occurrence of prostate cancer.<p cla...
