Brief Summary

Multiple Sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system, influenced by genetic, epigenetic, and immunological factors, as well as environmental factors such as nutrition. Medical nutrition therapy (MNT) has the potential to improve the quality of life for individuals with MS and enhance the disease course, particularly by reducing inflammation, providing neural protection, and regulating metabolic factors such as body weight. Recently, probiotic/synbiotic-supported studies have been conducted to investigate the effects of gut microbiota on the disease; however, only a few studies have thoroughly evaluated detailed dietary patterns. This study aims to examine the effects of the Mediterranean Diet, which is thought to have an impact on MS patients and many autoimmune diseases, along with synbiotic use, on the disease and quality of life of MS patients. All patients were given MNT during the study period. At the 6th week, the study group received probiotics while the control group received placebo twice a day as recommended. In the 1st (W1), 6th (W6) and 12th (W12) weeks, three- day food consumption and 24-hour physical activity records, anthropometric measurements, hand grip strength and biochemical indicators, Healthy Eating Index-2015 (HEI-2015), Beck Depression Inventory (BDI), Mediterranean Diet Adherence Scale (MEDAS), Multiple Sclerosis Quality of Life Scale-54 (MSQoL-54), Expanded Disability Status Scale (EDSS) scores were evaluated.

Outcome Measures

Primary Outcomes (2)

  • The quality of life in patients with multiple sclerosis

    The Multiple Sclerosis Quality of Life-54 (MSQOL-54) consists of two composite scores, the Physical Health Composite (PHC) and the Mental Health Composite (MHC), 13 subscales, and 2 single-item measures. The subscale and composite scores range from 0 to 100, with higher scores indicating better health-related quality of life.

    From enrollment (at week 1) to the middle (at week 6) and end (at week 12) of intervention.

  • The Expanded Disability Status Scale Score

    Disability was assessed using the Expanded Disability Status Scale (EDSS). The EDSS is an ordinal scale ranging from 0 to 10 in 0.5-point increments, where 0 indicates a normal neurological examination and 10 represents death due to multiple sclerosis. Higher EDSS scores indicate greater neurological disability.

    From enrollment (at week 1) to the middle (at week 6) and end (at week 12) of intervention.

Secondary Outcomes (19)

  • body weight

    From enrollment (at week 1) to the middle (at week 6) and end (at week 12) of intervention.

  • Waist Circumference

    Baseline (Week 1), Week 6, and Week 12

  • Mid-Upper Arm Circumference

    Baseline (Week 1), Week 6, and Week 12

  • Triceps Skinfold Thickness

    Baseline (Week 1), Week 6, and Week 12

  • Handgrip Strength

    Baseline (Week 1), Week 6, and Week 12

Study Arms (2)

Control Group

PLACEBO COMPARATOR

This group included participants aged 19-64 years who were diagnosed with RRMS and monitored at the MS outpatient clinic of Bakırköy Prof. Dr. Mazhar Osman Training and Research Hospital. The number of participants in the control group was 20.

Dietary Supplement: MNT+Placebo

Study Group

ACTIVE COMPARATOR

This group included participants aged 19-64 years who were diagnosed with RRMS and monitored at the MS outpatient clinic of Bakırköy Prof. Dr. Mazhar Osman Training and Research Hospital. The number of participants in the control group was 18.

Dietary Supplement: MNT+Synbiotic

Interventions

MNT+PlaceboDIETARY_SUPPLEMENT

The participants in this group received only MNT during the first 6-week period, and MNT+placebo supplementation (2 tablets a day) during the second 6-week period. The total intervention period was 12 weeks. The placebo product contained only vitamin C and starch. The number of participants in the control group was 20.

Control Group
MNT+SynbioticDIETARY_SUPPLEMENT

The participants in this group received only MNT during the first 6-week period, and MNT+synbiotic supplementation (2 tablets a day) during the second 6-week period. The total intervention period was 12 weeks. The synbiotic product contained Lactobacillus plantarum, Streptococcus thermophilus, Bifidobacterium lactis, Lactobacillus acidophilus, Bifidobacterium longum Enterococcus faecium, fructo-oligosaccharide, microcrystalline cellulose, corn starch, vitamin C, sweetener (xylitol and isomalt), milk flavor, anti-caking agent (hydroxypropyl methylcellulose), vanilla flavoring, anti-caking agent (magnesium salts of fatty acids). The number of participants in the control group was 18.
