The objective of this study was to provide a comprehensive understanding of the prevalence and incidence of rare diseases by systematically analyzing the available epidemiological data. We conducted a comprehensive search of English and Chinese databases, the Incidence and Prevalence Database, the Chinese Rare Disease Guideline, and the Taiwan Health Promotion Administration from 2010 to 2023. We identified the top diseases and regions based on epidemiological data and present the maximum, minimum, and median prevalence and incidence values in tables and forest plots. 1,264 prevalence and incidence data were retrieved from 277 studies, guidelines and official websites, covering 110 rare diseases (53.1%) and 32 regions (94.1%). In terms of geographical regions, incidence or prevalence data were available for 32 regions (94.1%), excluding Tibet Hui Autonomous Region and Macao Special Administrative Region. In terms of rate, 60 and 77 out of 207 diseases (29.0% and 37.2%) had available incidence and prevalence data, respectively. Eight diseases had an incidence rate equal to or greater than that of 1,000 patients per million. The present study provides a comprehensive epidemiological analysis and valuable insights into the prevalence and incidence of rare diseases in China. Our findings underscore the pressing need for sustained drug research and medical support for individuals and families impacted by rare diseases.</p>","PeriodicalId":14420,"journal":{"name":"Intractable & rare diseases research","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2024-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11145401/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141247225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mortality was of 65.8% of the cases with a mean death at 11.8 months. The mortality rate was 197.1 per 1,000 patients-years, which is significantly higher than other enteropathy types caused by defects in epithelial trafficking and polarity (such as <i>MOY5B, STX3, EPCAM, SPINT2, TTC37</i> and <i>SKIV2L</i>). Prematurity was also significant, with an average gestational age of 34.8 weeks. Antenatal signs were observed in 30 patients, including 14 cases of hydramnios. Three distinct phenotypic associations were identified: immune deficiency and multiple intestinal atresia without enteropathy (ID/MI), immune deficiency and enteropathy without atresia (ID/E), and immune deficiency with multiple intestinal atresia and enteropathy (ID/ MIA/E). The mortality rates for these groups were 91.6%, 47.3% and 55.5%, respectively (<i>p</i> = 0.03), at earlier age of mortality for the ID/MIA phenotype and a later one for the ID/E phenotype.

We performed a literature review of all studies about AAA in SVI patients, analyzing PubMed/MEDLINE, EMBASE, Web of Science (WOS), Google Scholar databases.
