Serum cystatin C as a biomarker in non-Hodgkin lymphoma and its relationship with paraoxonase 1 activity.

Background: This pilot study aimed to assess the potential of cystatin C (Cys C) as a biomarker in non-Hodgkin lymphoma (NHL) and to explore its association with paraoxonase 1 (PON1) activity.

Methods: The study included 44 patients with B-cell NHL and 44 healthy subjects. Cys C was measured using the Cobas e 801 analyser (Roche Diagnostics GmbH, Mannheim, Germany), while PON1 and TAS were measured on the ILab 300+ system (Instrumentation Laboratory, Milan, Italy).
