<h3>Objective:</h3> The study’s aim was to assess the impact of early-stage relapsing remitting multiple sclerosis (RRMS) on health-related quality of life (HRQoL). <h3>Background:</h3> Number of relapses, disability progression, and symptomatology can reduce RRMS patients’ HRQoL. However, limited information is available in early-stage patients. <h3>Design/Methods:</h3> A multicentre, non-interventional study was conducted. Adult patients with RRMS diagnosis, disease duration ≤3 years, and Expanded Disability Status Scale (EDSS) score between 0–5.5 were included. The 29-item Multiple Sclerosis Impact Scale (MSIS-29), SymptoMScreen (SyMS), 8-item Stigma Scale for Chronic Illness (SSCI-8), Hospital Anxiety and Depression Scale (HADS), Modified Fatigue Impact Scale (MFIS), 23-item Multiple Sclerosis Work Difficulties Questionnaire (MSWDQ-23), and EDSS were used to assess HRQoL, symptom severity, perception of stigma, depression and anxiety, fatigue, workplace barriers, and disability, respectively. Outcome measures associations were analyzed using Pearson correlation. <h3>Results:</h3> A total of 189 patients were included (mean age: 36.1±9.4 years, 71.4% female, mean disease duration: 1.4±0.8 years, median EDSS: 1.0 [IQR: 0–2]). Mean physical and psychological MSIS-29 sub-scores were 29.2±11.3 and 17.2±6.6, respectively. Mean SyMS score was highest for fatigue (1.6±1.4). Stigma prevalence was 56.6% (n=107/189) and 24.9% (n=47/189) of patients were probable anxiety cases. Physical and psychological MSIS-29 showed a significant correlation between them (rho=0.702, p<0.0001). Physical MSIS-29 subscale showed strong significant correlations with symptom severity, fatigue, and workplace barriers (rho=0.822, 0.778, 0.725, respectively, all p<0.0001). Psychological MSIS-29 subscale showed strong significant correlations with anxiety, depression, symptom severity, workplace barriers, and fatigue (rho=0.817, 0.791, 0.759, 0.722, 0.716, respectively, all p<0.0001). Symptom severity and workplace barriers were both strongly correlated with fatigue (rho=0.800, 0.774, respectively, p<0.0001). Stigma was moderately correlated with both MSIS-29 subscales (p<0.0001). <h3>Conclusions:</h3> RRMS can affect patients’ HRQoL even in early stages of the disease. Evaluating symptomatology impact at disease onset can help clinicians discerning when to apply early interventions, improving patient care and patients’ well-being. <b>Disclosure:</b> Dr. Castillo-Trivino has received personal compensation in the range of $500-$4,999 for serving on a Scientific Advisory or Data Safety Monitoring board for Biogen.
