Abstract

Multiple sclerosis (MS) is a chronic inflammatory immune-mediated disease of the central nervous system. Despite extensive investigations, many aspects of etiology and pathophysiology remain unclear. In multiple sclerosis patients, immune system reacts against autologous proteins in the myelin membrane. Most evidences support the hypothesis that both genetic and environmental factors contribute to disease development. But after the failure of genetic findings to explain the reason for the unequal incidence of MS in identical twins, investigators focused further on environmental factors such as vitamin D deficiency, smoking, living in different latitudes and perhaps the most importantly the role of viruses in people whom are genetically susceptible to MS. There is increasing evidence that viruses may play important role in MS pathogenesis following environmental triggers. Recently, studies focused on the role of herpes virus family, especially Epstein-Barr virus, human herpes virus 6 (HHV-6) and Varicella Zoster virus, as the virus is prevalent in society. This review mainly focused on the identification of important viruses with key role in MS the mechanism behind pathogenesis and describes the animal models of MS. The results of researches are shown strong evidence of the virus or antibodies to viral components in active plaques in MS affected patients, but still cannot be stated with certainty that one or more specific viruses are simultaneously trigger the disease. Further studies are required to prove the pathogenesis of viruses in MS.

Abstract

Multiple sclerosis (MS) is a chronic and multiphasic autoimmune disease which affecting the nervous system. Recently, neurotrophic factor secreting cells have been proposed as one of the best sources for cell therapy in MS disease. Therefore, this review study was done with aimed to introduce neurotrophic factor secreting cells and the role of neurotrophic factors in the treatment of MS. The present study, based on the Systematic Review and using multiple sclerosis, neurotrophin and cell therapy keywords, 98 articles were searched from various databases including Pubmed, SID, Springer, SinceDirect Magiran, Web of Sciences and the Google Scholar. After removing irrelevant and repetitive articles, 50 articles were selected. The results of these studies showed that cell-based therapies in MS have been designed with the aim of replacing destroyed cells or with the goal of neuronal support using neural growth factors. Neurotrophic factors secreting cells with the ability to migrate to neurological lesions and secretion of neurotrophic factors can play a major role in supporting neural tissue and preventing its destruction. These factors, through tyrosine kinase receptors, have a variety of effects on the development and proper functioning of neurons. On conclusion, neurotrophic factor secreting cells due to the secretion of a wide range of neural growth factors which required for neural development might be one of the ideal cell sources for cell-based therapy in MS disease.

Abstract

Background and Objective: Multiple Sclerosis (MS) is a neurologic necrotic and chronic illness that causes by demyelination in CNS. One of the common clinical symptoms in MS is cognitive disorders. The most common cognitive defects in patients with MS are reduction of memory and information processing rate hippocampus functions in brain are memory and learning. This study was done to determine the function mechanism of memory discover by study on hippocampus. Nowadays tendency of herbal therapy is increased because of drug's side effects. This study's purpose that is from experimental typ effect of compaind extract of Portulaca olerace, Urtica dioica and Boswellia serrata on memory and number of neurons in CA1 area of hippocampus in induced multiple sclerosis rats.
Methods: In this experimental study 30 male adult rats were randomly allocated into control group, sham group (salin injection), (MS + salin) group, (MS + mixture extract, dose of 200 mg/kg), (MS + mixture extract, dose of 400 mg/kg). MS model was induced by intra hippocampal injection a single dose of ethidium bromide (0.01% ethidium bromide sulotion in 0.9% salin) and in 3 microlitre volume with 1 microlitre in minute rate intraperitoneally. Compaind extract of Portulaca olerace, Urtica dioica and Boswellia serrata were injected as the treatment for 21 days. The shuttle box test was used for evaluation of memory. Dissector method was used for neural density in CA1 of hippocampus. Histopathology method was used for evaluation of the alteration of cells.
Results: Neural density in MS induced group was singnificantly reduced in comparison with control and sham groups (P<0.05). Neural density was singnificantly increased in treatment groups in comparison with MS induced group (P<0.05). Histological results showed that induction of MS caused the disrution of neuron cells in compare to controls, but intraperitonal injection of compaind extract cause neurogenesis in tertment groups. Memory in MS induced group was singnificantly reduced in comparison with control and sham groups (P<0.05), but memory was singnificantly increased in treatment groups in comparison with MS induced group (P<0.05).
Conclusion: Compaind extract of Portulaca olerace, Urtica dioica and Boswellia serrata with dosages of 200 and 400 mg/kg/bw due to neurogenesis and amilioration can effective in memory recovery and neural necrosis in MS disease.

Abstract

Background and Objective: Multiple sclerosis (MS) is one of the most common diseases of the central nervous system. MS is more common among women. Gait pattern dysfunction is a relevant symptom in these patients. This study was conducted to compare the electromyography activity of selected lower extremity muscles and the ellipse area of center of pressure during unplanned gait termination in female patients with multiple sclerosis and healthy individuals.
Methods: This case-control study was performed on 10 female patients with MS (classified based on the EDSS scale) and 10 healthy subjects matched for height, age and weight. Electromyography activity of rectus femoris (RF), vastus medialis (VM), vastus lateralis (VL), biceps femoris (BF), semitendinosus (SM), gastrocnemius medius (GM) and tibialis anterior (TA) and center of pressure (CoP) recorded using foot pressure system during unplanned gait termination. Subjects were instructed to stop, as soon as possible, in response to an auditory cue delivered when the heel strike phase accidentally.
Results: Vastus Lateralis muscle activity was significantly higher in able-bodied group than patients (P<0.05), whereas in the patient group gastrocnemius medius muscle activity increased significantly (P<0.05). Also, the ellipse area of center of pressure significantly reduced in MS group in compered to able-bodied group (P<0.05).
Conclusion: Increased gastrocnemius medius muscle activity in MS patients may be due to their attempt to slow down the displacement of the center of mass to limit the tibia forward translation consequently, attempting to control balance as a strategy to limit the ellipse area of center of pressure to prevent fall.

Abstract

Background and Objective: Multiple sclerosis (MS) is a common neurological disease that increases oxidative stress and causes immune system disorders. Curcumin is the active component of turmeric with anti-inflammatory properties. This study was conducted to determine the effects of curcumin on cortisol, catalase, and nerve growth factor (NGF) expression in an animal model of MS.
Methods: This experimental study was conducted on 30 female Wistar rats. Experimental autoimmune encephalomyelitis (EAE) was chosen as an experimental model of MS. The rats were divided into 3 groups of 10, including a healthy control group, an affected group, and a group treated with curcumin. The disease was induced by immunization of rats with homogenized guinea pig spinal cord and Freund's complete adjuvant. Then, the immunized animals were allocated into two equal groups. Treatment with curcumin (100 mg/kg daily) was started 12 days after the immunization when the rats showed the first symptoms of neurologic disability. The treatment was continued until day 24 post-immunization. Simultaneously, the EAE group received the medicine solvent (distilled water). Finally, the rats' weights as well as cortisol, catalase, and NGF levels were measured in the study groups.
Results: Curcumin significantly increased the level of cortisol to a level equal to that of healthy rats (P<0.05). It also significantly increased the expression of NGF and reduced the amount of catalase in the affected rats (P<0.05). The curcumin administration significantly increased the overall weight of rats with MS but had no significant effect on the spleen weight of the treated rats.
Conclusion: Curcumin can be beneficial for treating EAE by reducing the destructive effects of oxidative damage and increasing NGF.

Abstract

Background and Objective: Multiple sclerosis (MS) is an autoimmune disease that targets the central nervous system. Various studies have shown that several factors influence this disease’s occurrence and prevent its progress. Multiple studies have shown that several factors affect this disease’s occurrence and prevent its progress. Helicobacter pylori can be mentioned among these factors. This study was conducted to determine Helicobacter pylori infection in MS patients and healthy individuals.
Methods: This case-control study was conducted on 100 patients with MS (mean age: 36.99±9.87 years) and 100 healthy subjects (mean age: 38.05±11.38 years) in Golestan province, north of Iran during 2021. The case group included eighty relapsing-remitting cases and twenty secondary progressive cases. Blood samples were taken from both groups, and after separating the serum using the ELISA test, anti-Helicobacter pylori antibody (IgG) was detected by determining the antibody titer.
Results: Helicobacter pylori IgG in the MS and control groups was 21% and 44%, respectively (P<0.05). The mean concentration of IgG in the case group was significantly lower than the control group (13.48±10.83 versus 19.78±16.14 AU/ml). The percentage of positive cases of IgG antibody against Helicobacter pylori in the relapsing-remitting and secondary progressive group of patients with MS was determined as 21.2% and 20%, respectively, and the difference between these two groups was not statistically significant.
Conclusion: The history of Helicobacter pylori infection is less than two times in patients with MS compared to healthy people probably indicate the protective role of this bacterium against this disease.

Abstract

Background and Objective: Physical disability caused by multiple sclerosis (MS) increases MS patients' need for support from others. Medication adherence is one of the main success factors in the treatment of chronic diseases, which is influenced by various factors. This study aimed to determine the relationship between perceived social support and medication adherence in patients with MS.
Methods: This descriptive-analytical study was conducted on 110 patients (70 women and 40 men) aged 39±9 years with MS who visited the 2 medical training centers of Isfahan University of Medical Sciences (Kashani and Al-Zahra), Isfahan, Iran during 2021. After sampling by the systematic random method, the data were collected by interviews and using Zimmet's Perceived Social Support Scale (MSPSS) and the Morisky Medication Adherence Scale (MMAS-8).
Results: The mean and standard deviation of the scores of medication adherence and perceived social support were 6.10±1.72 and 62.83±14.97, respectively. According to the Pearson correlation coefficient, perceived social support did not show any significant relationship with medication adherence (r=0.185, P=0.053). Perceived social support showed a statistically significant relationship with income satisfaction (F=4.54, P=0.01), the pattern of clinical course (F=2.95, P=0.03), difficulty in accessing medical care (t=-2.29, P=0.02), and clinical symptoms, including motor (t=-3.72, P=0.001), balance (t=-3.23, P=0.002), and urinary disorders (t=-2.53, P=0.01).
Conclusion: Perceived social support in patients with MS did not cause medication adherence.
