Familial Mediterranean fever research activity in the Arab world: the need for regional and international collaborations

Abstract

Background: Familial Mediterranean fever (FMF) is an autoinflammatory, multisystem disease affecting the populations of the Mediterranean basin. Aims: The aim of this study was to assess the research input of Arab countries on FMF between 2004 and 2019. Methods: The Medline database (PubMed) was accessed for FMF-related publications. The number of publications was normalized to average: population size, GDP and number of physicians for every country. VOSViewer was used to create a co-occurrence bibliographic map. Results: Between 2004 and 2019, 69 articles relating to FMF were published in the Arab world, accounting for 0.03% of the total number of publications originating in Arab countries, and 3.60% of all articles relating to FMF worldwide. After normalizing to average population size, GDP and number of physicians, Lebanon ranked first with 4.44, 0.64 and 1.99 publications per million persons respectively. Moderate positive correlations were found between number of publications and average population size (r = 0.385) and average number of physicians (r = 0.513). Half of the articles were published in journals ranked Q1 and Q2. An abundance of keywords relating to genetics hint at a main focus on the genetic aspect of the disease. Conclusion: The low number of publications could be a result of the absence of research funding and the political and military instability in the Arab world. Given that many articles were published in high quality journals, Arab countries should focus on providing a clinical aspect to their studies and working on regional and international collaborations.
