Nutritional and Biochemical Parameters Among Multiple Sclerosis Patients: A Case-Control Study.

Background The pathogenesis and prognosis of multiple sclerosis (MS) is an area of active medical research. Dietary and biochemical parameters such as serum 25-dihydroxycholecalciferol, magnesium, and potassium play a role in disease progression. This study aimed to compare the nutritional status and biochemical profile of patients with and without MS. Methodology This case-control study included a total of 112 participants (56 in the control group and 56 in the MS group). The participants' socioeconomic and demographic profiles, nutritional status, and biochemical details were all gathered using history, patient files, and records. The effect of these parameters on the presence of MS was evaluated using a decision tree model. Student's t-test and Mann-Whitney U test were performed to compare these parameters. Results A decision tree model was developed with an accuracy rate of 86.52%. The vitamin and mineral intake of the groups showed significant statistical differences (p = 0.001). The differences were important in terms of biochemical parameters, especially serum levels of 25-dihydroxycholecalciferol and potassium. Conclusions The key parameters that varied between MS patients and the control group, according to the constructed decision tree, were serum levels of 25-dihydroxycholecalciferol, magnesium, calcium, potassium, and carbohydrate intake. Nutritional measures against MS can be taken based on the decision tree.
