The Chinese researchers have made significant progress in studying rare diseases in the recent years. From 2000 to 2014, 269 out of 1892 clinically relevant original research papers published on high impact journals by Chinese institutions, and 2678 out of 6040 clinical trials conducted by Chinese institutions and registered at ClinicalTrial.gov are focused on rare diseases. The number of research papers and of clinical trials has shown a steady trend of increase. Creating public databases for rare disease will escalate progress in rare disease and enable multicenter studies.
Rare diseases have been receiving increasing public attention in China . Currently, approximately 15.6 million people in China are afflicted with rare diseases , a relatively large patient population that can contribute to and benefit from medical research. The Chinese government has taken steps in promoting rare disease awareness, facilitating medical research, and providing patient resources. Examples are the upcoming establishment of a Rare Diseases Prevention and Treatment Law and the foundation of the Chinese Organization for Rare Disorders . In this letter, we would like to highlight the tremendous amount of progress that has been made by Chinese researchers in the recent years and additional steps that are currently underway to facilitate future research and collaboration.
Methods and results
Second, we looked at clinical trials that were conducted by Chinese institutions and registered at ClinicalTrials.gov from 2000 to 2014. There was a total of 6040 clinical trials, 2678 (44 %) of which studied rare diseases. There has been an exponential increase of clinical trials since 2004 (Fig. 1b).
Evidently, multiple centers in China have been studying rare diseases, resulting in a tremendous increase in the number of high-quality publications and clinical trials. However, most of the data are only available to local researchers. There is a need for open data access and a nationwide data-sharing platform. Examples of public database include The Cancer Genome Atlas in the United States and The European Genome-phenome Archive in Europe . Creating a public database is a daunting task that requires collaborative efforts by researchers in the Chinese medical research community. However, its establishment will bring drastic change to the research environment in China, creating abundant opportunities for multi-center studies.
