Some Aspects of the Evaluation of Brush Border Enzymuria Originating from Proximal Renal Tubules as Screening Test in Patients with Psoriatic Arthritis

Aim: To compare diagnostic values and laboratory variables of alanine - aminopeptidase (microsomale AAP), γ-glutamyl transferase (γ−GT),β2-microglobuline (β2-M), C Reactive Protein (CRP) and index for disease activity (PASI) in early diagnosis in previously untreated Psoriatic arthritis (Psa). To determine the effect of untreated Psoriatic arthritis on tubular function, sensitivity of the Brush Border region as well as the diagnostic value of the enzymes originating from proximal renal tubules.
