Introduction: The interaction between COVID-19 and pre-existing neurological diseases remains poorly understood, highlighting the need to identify key prognostic markers. This study aimed to characterize the clinical and laboratory profiles and identify predictors of peripheral oxygen saturation (SpO₂) in hospitalized patients with pre-existing neurological disorders and COVID-19. Methods: This retrospective cross-sectional study included 128 hospitalized COVID-19 patients with neurological diseases at Taleghani Educational Hospital in Abadan, Iran, from March 2020 to March 2022. Demographic, clinical, and laboratory data were extracted from the Hospital Information System and patient files. Results: On average, patients exhibited elevated levels of key laboratory markers, including renal (creatinine, BUN), hepatic (ALP, direct bilirubin, AST, ALT), coagulation (PT, aPTT, INR), and inflammatory (ESR) indicators. The mean peripheral oxygen saturation (SpO₂) was below the normal range (91.71 ± 7.88%). Multivariable linear regression revealed that in-hospital mortality (B = −5.93; P < 0.001), increased respiratory rate (B = -0.10 per breath/min; P = 0.03), and intubation (B = −5.58; P < 0.001) were significantly associated with lower SpO₂ levels. Conclusion: In this cohort of neurological patients with COVID-19, dysregulation of renal, hepatic, and coagulation markers was common. Critically, hypoxemia (lower SpO₂) was strongly associated with adverse outcomes, including mortality, respiratory distress, and the need for mechanical ventilation. These findings underscore the importance of monitoring these specific biomarkers and SpO₂ to improve risk stratification and guide clinical management in this high-risk patient population.
