Background Multiple sclerosis (MS) is a chronic inflammatory and autoimmune disease affecting various inflammatory and nutritional parameters. Therefore, this study aimed to investigate the relationship between the Body Mass Index (BMI) of MS patients and the serum levels of leptin, orexin‐A, and Transforming Growth Factor β (TGF‐β). Methods This cross‐sectional study included 25 patients suffering from MS and 40 healthy individuals as the case and control groups, respectively. The serum levels of leptin, orexin‐A, and TGF‐β were assessed in the participants using the Enzyme‐Linked Immunosorbent Assay methods. Moreover, data were analyzed using the descriptive statistical indices, t‐test, chi‐square test, and linear regression test. Results According to our results, the participants’ mean age was 38.04 ± 7.53 and 40.23 ± 5.88 in the case and control groups, respectively. Also, the groups were not significantly different in gender, age, alcohol consumption, and smoking (p > 0.05). It was found that the mean serum levels of orexin‐A and TGF‐β were significantly lower in the MS patients compared to the control group, while the mean serum leptin levels were significantly higher (42.8 vs. 18.9 ng/ml, p < 0.001). Moreover, there was no significant relationship between the BMI of the MS patients and their serum levels of orexin‐A, TGF‐β, and leptin (p > 0.05). Conclusions In conclusion, we found significantly lower levels of orexin‐A and TGF‐β and a significantly higher level of leptin in the MS patients compared to the control group. In addition, there was no significant relationship between the BMI and the serum levels of orexin‐A, TGF‐β, and leptin in MS patients.

Backgrounds: Multiple Sclerosis (MS) is a chronic inflammatory and autoimmune disease linked to several inflammatory and dietary parameters. This study was carried out to determine the relationship between serum leptin, orexin-A, and TGF-β levels with BMI in MS patients.Methods and results: In this cross-sectional study, 25 relapsing-remitting multiple sclerosis (RRMS) patients and 40 healthy controls were enrolled. The serum level of Leptin, Orexin-A, and TGF- were measured by the Enzyme-linked immunosorbent assay (ELISA). The data was analyzed using descriptive statistics, t-test, Chi-square test, and Linear regression test. A total of 65 volunteers, including 25 MS patients and 40 healthy, were enrolled in the study. The mean age of individuals in the case and control groups was 38.04 ± 7.53 and 40.23 ± 5.88. There were no statistically significant differences between the case and control groups regarding gender, age, alcohol, and cigarette use (P>0.05). The mean serum levels of Orexin-A and TGF-ß were lower among multiple sclerosis patients than in healthy controls, but leptin was higher (42.8 vs. 18.9 ng/ml, P<0.001). The relationship between BMI and serum levels of Orexin-A, TGF-ß, and Leptin among Multiple Sclerosis patients was not statistically significant (P > 0.05).Conclusion: Our results showed that the serum levels of Orexin-A and TGF-β were significantly lower. The serum level of leptin was higher among multiple sclerosis patients than among healthy controls. Also, there was no statistically significant relationship between BMI and serum levels of Orexin-A, TGF-ß, and Leptin among multiple sclerosis patients.
