Multivariable model consisting of clinical and biological markers for time to first treatment in CLL patients: Preliminary results from single centre experience.

Introduction: The clinical course for patients with chronic lymphocytic leukaemia (CLL) is extremely heterogeneous; one of the most important challenges in the clinical management of these patients is the decision on initiating their treatment, but there is no available prognostic system that will resolve this issue. Usually, criteria for active disease are used to initiate therapy. Recently, some authors have proposed prognostic models, scoring systems involving a set of clinical and biological risk factors and estimates of individual patient survivals.

Diagnostic value of brush border enzymes of the proximal renal tubules in rheumatoid arthritis.

Background: Proximal tubules of the kidney have a dominant function in the excretion of different enzymes in the urine. These enzymes can be used as markers for secondary renal damage under the action of different diseases, medicines, and toxins. The aim of this study was to evaluate the values of alanine aminopeptidase (AAP), gamma-glutamyl transferase (gamma-GT), and beta2 microglobulin (beta2m) in urine of patients with untreated rheumatoid arthritis (RA) and to define the possible association between untreated rheumatoid arthritis and tubular function at the brush border region.
