The aim of our study was to evaluate the possible association between IBD and MS in a cohort of patients with IBD. In a retrospective study, we examined the medical records of 5739 patients with a confirmed diagnosis of IBD followed in our clinic between 1978 and 2022.

For each of the patients with MS identified, more than ten patients without MS were analyzed. The 14 MS cases were then compared with 342 controls. From the 14 patients with MS, 12 (85.7%) were female and 2 (14.3%) were male, while in the control group, 158 (46.2%) were female and 184 (53.8%) were male (p = 0.004). As for therapy, significant differences were found in mesalazine (5 (41.7%) cases vs. 317 (92.7%) controls, p < 0.0001) and anti-TNF treatment (0% cases vs. 26.6% controls, p = 0.03, respectively) at the time of MS diagnosis. Moreover, a Kaplan–Meier curve analysis showed that the 20-year survival probability was 98.4% for patients with IBD, while for patients diagnosed with MS and IBD it was 82.1% (p = 0.02). In conclusion, patients with IBD have a similar risk of developing MS compared to the general population, but female sex appears to increase the risk. Indeed, life expectancy at 20 years for patients with IBD and MS is lower than for patients with IBD alone.

Abstract

Being two immune-mediated diseases (IMIDs), the association between multiple sclerosis (MS) and inflammatory bowel disease (IBD) is plausible, but data in the literature are conflicting. The aim of our study was to evaluate the possible association between IBD and MS in a cohort of patients with IBD. In a retrospective study, we examined the medical records of 5739 patients with a confirmed diagnosis of IBD followed in our clinic between 1978 and 2022. Among these patients, we identified 14 with MS, with a prevalence of 0.24%. The reported prevalence of MS in the general population in Northern Italy in 2021 was 0.18% (p = 0.24). For each of the patients with MS identified, more than ten patients without MS were analyzed. The 14 MS cases were then compared with 342 controls. From the 14 patients with MS, 12 (85.7%) were female and 2 (14.3%) were male, while in the control group, 158 (46.2%) were female and 184 (53.8%) were male (p = 0.004). As for therapy, significant differences were found in mesalazine (5 (41.7%) cases vs. 317 (92.7%) controls, p < 0.0001) and anti-TNF treatment (0% cases vs. 26.6% controls, p = 0.03, respectively) at the time of MS diagnosis. Moreover, a Kaplan–Meier curve analysis showed that the 20-year survival probability was 98.4% for patients with IBD, while for patients diagnosed with MS and IBD it was 82.1% (p = 0.02). In conclusion, patients with IBD have a similar risk of developing MS compared to the general population, but female sex appears to increase the risk. Indeed, life expectancy at 20 years for patients with IBD and MS is lower than for patients with IBD alone.
