IR-MS: Insulin Resistance in Egyptian Patients With Multiple Sclerosis
Study Details
Study Description
Brief Summary
The goal of this three-phase interventional study is to determine the prevalence of Insulin resistance in non-diabetic patients with multiple sclerosis in Egypt
The main questions it aims to answer are:
-
what is the prevalence of insult resistance among Egyptian patients with Multiple sclerosis?
-
what are the effects of insulin resistance on multiple sclerosis disease activity and progression
-
what are the effects of treating insulin resistance on multiple sclerosis disease activity and progression participants with MS will be tested for IR to determine its prevalence, in the 2nd phase a group of MS patients with IR will be compared with another control group of MS patients without IR for clinical, laboratory, and radiological markers of disease activity and progression twice at baseline and after 1 year. in the 3rd phase, patients with IR will be divided into 2 groups one who will receive appropriate treatment for IR and the other group without treatment of IR and will be compared by the end of the 2nd year for clinical, laboratory and radiological markers of disease activity and progression

Detailed Description
In this longitudinal, three-phase, case-control, interventional study, with 250 patients with multiple sclerosis diagnosed according to the 2017 McDonald's criteria will be enrolled. Frist diagnosis of cases of insulin resistant MS patient out of the total sample of MS through estimation of fasting blood glucose, insulin level, and homeostatic model assessment of insulin resistance (HOMA-IR) index. Other supportive indices like waste circumference, hemoglobin A1c, and lipid profile will be used. At the end of first phase, prevalence of IR and associated metabolic syndrome will be determined. In the second phase of the study, patients will be divided into two groups with and without IR. Cognitive status will be evaluated with BICAMS test. Physical disability will be evaluated by the EDSS score, 9-hole pig and 25-foot-walk test. Patients will be assessed for other comorbid conditions like fatigue and depression. Serum light chain neurofilaments as a laboratory marker for axonal degeneration will be used. Diffusion tensor imaging with a fully automated too (volbrain) will be used. Patients in the second phase of the study will be evaluated both at baseline and after one year. In the third phase, patients with IR will be divided randomly into two equal groups (1:1) using closed envelope: intervention group who will receive appropriate treatment for IR and a control group with placebo treatment (without IR treatment) and by the end of the second year all groups will be evaluated blindly using the same evaluating measures (clinical, laboratory and radiological)
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Multiple sclerosis patients without insulin resistance Cognitive status will be evaluated with BICAMS test. Physical disability will be evaluated by the EDSS score, 9-hole pig and 25-foot-walk test. Patients will be assessed for other comorbid conditions like fatigue and depression. Serum light chain neurofilaments as a laboratory marker for axonal degeneration will be used. brain imaging will be done with with Diffusion tensor imaging. |
|
| Multiple sclerosis patients with treated insulin resistance before and after treatment of insulin resistance Cognitive status will be evaluated with BICAMS test. Physical disability will be evaluated by the EDSS score, 9-hole pig and 25-foot-walk test. Patients will be assessed for other comorbid conditions like fatigue and depression. Serum light chain neurofilaments as a laboratory marker for axonal degeneration will be used. brain imaging will be done with with Diffusion tensor imaging. |
Other: treatment of insulin resistance with appropriate modality according to each patient
insulin resistance will be treated with either diet alone or combined diet and appropriate pharmacological treatment with the net result of normalization of HOMA IR index
|
| Multiple sclerosis patients with untreated insulin resistance at the end of the 1st and 2nd year of the study, Cognitive status will be evaluated with BICAMS test. Physical disability will be evaluated by the EDSS score, 9-hole pig and 25-foot-walk test. Patients will be assessed for other comorbid conditions like fatigue and depression. Serum light chain neurofilaments as a laboratory marker for axonal degeneration will be used. brain imaging will be done with with Diffusion tensor imaging. |
Outcome Measures
Primary Outcome Measures
- prevalence of insulin resistance among Egyptians with multiple sclerosis [this will be determined in the first 2 months of the study (phase 1 of the study)]
to determine the prevalence of Insulin resistance among Egyptian patients with multiple sclerosis using the homeostatic model assessment of insulin resistance (HOMA-IR) index
Secondary Outcome Measures
- effect of insulin resistance on Multiple sclerosis disease activity [this evaluation will be done at 2 points; at the beginning and the end of the first year of the study (phase 2)]
disease activity (indicated by either annualized relapse rate or radiological activity) will be compared between MS patients with and without Insulin resistance
- effect of insulin resistance on Multiple sclerosis disease progression [this evaluation will be done at 2 points; at the beginning and the end of the first year of the study (phase 2)]
disease progression (indicated by either changes in BICAMS scores, or radiological markers of progression) will be compared between MS patients with and without Insulin resistance
- effect of treating insulin resistance on Multiple sclerosis disease activity [this evaluation will be done at 2 points; at the beginning and the end of the second year of the study (phase 3)]
disease activity (indicated by either annualized relapse rate or radiological activity) will be compared between MS patients with treated and untreated Insulin resistance
- effect of treating insulin resistance on Multiple sclerosis disease progression [this evaluation will be done at 2 points; at the beginning and the end of the second year of the study (phase 3)]
disease progression (indicated by either changes in BICAMS scores or radiological markers of progression) will be compared between MS patients with treated and untreated Insulin resistance
