Volume 80, Issue 1 (4-2022)
Abstract
Background: Multiple sclerosis (MS), as an inflammatory autoimmune disease and chronic degenerative central nervous system degeneration, often occurs in early adulthood. One of the common and debilitating symptoms of this disease is fatigue, which can affect up to 80% of patients with MS. This study aimed to evaluate the effectiveness of magnetic field therapy on fatigue in patients with MS.
Methods: Present study is a single-blind randomized clinical trial (RCT) that Was conducted on patients with multiple sclerosis from March 2019 to September 2021. In this study, 46 patients who met our inclusion criteria were divided into two groups randomly: magnetotherapy intervention and control group. The intervention was performed in the form of a pulsed magnetic field with a frequency of 15 Hz and an intensity of 4.5 Millie Tesla. In order to blind patients, they were unaware of the intervention or control group, and the technician in charge of the treatment and the statistician knew about it. Data were then collected and recorded using the Fatigue Severity Scale, the Patient Health Questionnaire, and the Epworth Sleepiness Scale Questionnaire.
Results: Of the 46 patients studied, 22 (48%) were male and the rest of them were female [24 cases (52%)]. The mean age of men and women was 34.4±7.3 and 33.5±1.7 years, respectively. Among the intervention and control groups, 8 people took amantadine equally in each group. In the magneto-therapy intervention group, the mean severity of fatigue reduced from 4.91±0.86 to 4.27±1.10, which was significant (p=0.024). In our control group, the mean intensity of fatigue reduced from 4.83±0.83 to 4.37±0.81, which was significant statistically (p=0.028). Although, the difference between the response of the two groups to treatment was not significant (p=0.382).
Conclusion: Due to the lack of significant differences in the reduction of fatigue severity, this treatment is not recommended for the treatment and management of fatigue in patients with MS.

Evaluation of the relationship between axon injury and clinical symptoms in patients with multiple sclerosis using diffusion tensor MRI imaging

Abstract

Background: Magnetic resonance imaging (MRI) is a non-invasive imaging technology that shows detailed anatomical and pathological images. It is often used for disease detection, diagnosis, and treatment monitoring, in particular with neurodegenerative diseases, such as Multiple sclerosis (MS), Alzheimer's and amyotrophic lateral sclerosis. However, conventional MRI provides only qualitative information and cannot distinguish between myelin and axon destruction. One of the new methods in early detection for axonal injury is the DTI sequence, which can be used to observe and quantify the various dimensions of these plaques, including the direction of diffusion and average diffusion. In other words, in DTI, quantitative data from the image helps to estimate the physiological and pathophysiological information of plaques in the brain. This study aimed to investigate the relationship between DTI parameters including FA, MD, RD, AD, axon injury and severity of clinical symptoms in patients with MS.
Methods: This is a cross-sectional control case study that was performed in Isfahan Milad Hospital from December 2020 to August 2021. DTI imaging was performed on 41 patients with MS and 41 normal individuals, and DTI indices including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) in different areas of the brain were evaluated. A visual analog scale (VAS) was used to assess the severity of clinical symptoms in patients. The relationship between DTI indices and the severity of clinical symptoms and axon injury was analyzed by the Kolmogorov-Smirnov test.

Results: Correlation analysis showed that there is a significant correlation between DTI sequence parameters and the VAS visual analog scale (P˂0.05) and according to the positive values of the correlation coefficient, there was a positive and significant relationship between VAS and the mentioned parameters and with increasing parameters. The DTI sequence of the Visual Analog Scale (VAS) was significantly increased.

Conclusion: Indicators obtained from the DTI sequence can be used in the prognosis of the disease and the estimation of the severity of clinical symptoms during the patients' involvement.
