    Neutrophil Gelatinase-Associated Lipocalin (NGAL) and Inflammatory Markers in Schizophrenia: A Comparative Analysis of Drug-Naive Schizophrenia Patients, Remitted Patients, and Healthy Controls
    (JOURNAL OF PSYCHIATRIC RESEARCH, 2024) Ciftci, Hatice; Asut, Gonca; Kaya, Hasan; Cakmak, Isik Batuhan; Yilmaz, Meltem Aydiner; Copur, Ahmet; Calci, Esin; Oguz, Esra Firat; Turhan, Turan; Goka, Erol
    This study aims to examine the plasma concentrations of NGAL and other inflammatory parameters, including TNF-alpha, IL-1 beta, and IFN-gamma, in schizophrenia patients and healthy volunteers. It also investigates potential associations between these biomarkers and symptom severity in schizophrenia and the utility of NGAL as a potential diagnostic and monitoring biomarker for schizophrenia. The study included 49 drug-naive schizophrenia patients (DNS), 59 patients with schizophrenia in remission (REM) on antipsychotic treatment, and 58 healthy volunteers (HC). The Positive and Negative Symptoms Evaluation Scale (PANSS) was utilized to assess the severity of symptoms in schizophrenia patients. Plasma levels of TNF-alpha, IL-1 beta, IFN-gamma, and NGAL were measured for all participants. NGAL levels were significantly lower in the DNS group than in HC. Significantly lower TNF-alpha levels were observed in both the DNS and REM groups compared to the HC group. Notably, a statistically significant positive correlation was detected between TNF-alpha and NGAL levels. The findings of this study are noteworthy, as they demonstrate that drug-naive individuals with schizophrenia exhibit significantly diminished levels of NGAL and TNF-alpha compared to healthy controls. These identified biomarkers hold promise for providing valuable insights into the complex and evolving pathophysiology of schizophrenia.
