Review of the diagnosis and clinical features of multiple sclerosis in China

The incidence and prevalence, diagnosis, and treatment of multiple sclerosis in China: a narrative review

In 2018, the first list of rare diseases was published by the National Health Council of China, and multiple sclerosis (MS) was included in this list. Since then, the Chinese government and neurologists have made efforts to improve the clinical outcomes of patients with MS. During last few years, the incidence of MS in China was also investigated. The early and accurate diagnosis of MS was improved due to the application and promotion of magnetic resonance imaging and new diagnosis criteria. The market for and medical insurance access to disease-modifying therapies (DMTs) has been greatly accelerated, which has provided more treatment options and improved clinical outcomes for patients with MS, as well as reduced treatment cost. The pattern of MS in China is gradually changing, from delayed to early diagnosis, and from no treatment to treatment with DMTs during remission. This narrative review aimed to summarize an update to the status of MS in China, including incidence and prevalence, diagnosis, and available treatments. This would help to better understand the diagnosis and treatment gap between mainland China and other Asian regions, demonstrating the necessity of accurate diagnosis and optimized treatment of MS in China.

Factors associated with the healthcare expenditures of patients with multiple sclerosis in urban areas of China estimated by a generalized estimating equation

Background: Multiple sclerosis (MS) has a significant healthcare burden. This study examined the medical cost and out-of-pocket (OOP) expenses, and quantified the impact factors contributing to the costs. Methods: This is a retrospective study in 77 Chinese urban cites from 2013 to 2015. The data included the details of the utilization of medical resources, cost, and reimbursement ratio of all patients with a diagnosis of MS. A generalized estimating equation model was used to estimate the factors influencing the direct medical cost and OOP expenses for in- and outpatients. Results: A total of 267 patients with MS were identified. The mean cost per in- and outpatient was respectively 16996.2 and 2294.2 renminbi ($2768.12 and $373.65, €2087.16 and €281.73). Approximately 27% of the expenses were paid by the patients OOP. Factors contributing to high cost and high OOP expenses for inpatients were tertiary hospital admission, length of stay and residence in the east regions of China. Females and outpatients with resident insurance paid more OOP. Conclusion: This study illustrates the medical costs and burden of MS in Chinese patients and provides real-world data on MS that are essential for the improvement of health policies.

Optic neuritis, the most common initial presenting manifestation of multiple sclerosis in northern Iran

BACKGROUND

Multiple sclerosis (MS) is an inflammatory and demyelinating disease of central nervous system (CNS). The aim of the present study was to determine the type and the frequency of initial presenting symptoms in patients with MS and their relation with demographic characteristics in Babol, northern Iran.

METHODS

All patients of this study were recruited over a ten year period from 2002 to 2012 from single neurologic clinic. Diagnosis of MS was confirmed according to the McDonald criteria, demographic and clinical features Then, all the clinical findings and demographic variables including: age, sex, marital status, age at onset, education, place of residence, disease duration, initiation pattern of disease have been collected. Expanded Disability Status Scale (EDSS) was used for the evaluation of disability at the onset of disease. Data analysis was performed by chi-square test.

RESULTS

A total of 263 consecutive MS patients with the age range of 17 to 61 yr were examined. Optic neuritis was the most prevalent initial presenting symptom in 123 (46.8%) patients followed by sensory disturbances as the second common presenting symptom of MS. Significant difference was found between patients with or without optic neuritis and the onset age of the disease and EDSS (p<0.001). The mean EDSS score at the time of initial presentation was 1.67±0.77.

CONCLUSION

The findings of this study indicated that optic neuritis is the most prevalent initial presentation of MS in the geographic region of northern Iran. In patients less than 30 years, development of visual disturbances justifies neurologic examination.
