Serum Neutrophil Gelatinase-Associated Lipocalin Levels in Acute Brucellosis and Brucellar Spondylodiscitis

Mikrobiyol Bul. 2022 Jan;56(1):1-10. doi: 10.5578/mb.20229901.ABSTRACTBrucellosis is a zoonotic infectious disease caused by Brucella spp., an intracellular bacterium. The complications of acute Brucellosis may affect all organs and systems. The most common complication of the disease is musculoskeletal system involvement. The neutrophil gelatinase-associated lipocalin (NGAL) is a marker of neutrophil formation and acts as a siderophore-binding protein to prevent bacterial iron uptake and its use as a marker in the diagnosis and follow-up of bacterial infections is being investigated. The aim of this study was to measure the serum levels of NGAL in patients with acute Brucellosis and Brucellar spondylodiscitis, and to determine whether there is a correlation between NGAL levels and the progression and complications of the disease. This prospective case control study was conducted with 240 patients and 120 healthy controls. The diagnosis of acute Brucellosis was established when a person was asked to take an STA test due to clinical symptoms within the past eight weeks, and the test result that exceeded 1/160, or a 4-fold titer increase was found in the STA test after an interval of two weeks, and/or there was Brucella spp. growth in the blood culture. A contrasted lumbar magnetic resonance (MR) scan was performed on patients diagnosed with acute Brucellosis who had lower back pain. Presence of spondylodiscitis was assessed radiologically with contrasted lumbar MR images. NGAL...
