Contribution of Arab Countries to Familial Mediterranean Fever Research: a PubMed-based bibliometric analysis.

Familial Mediterranean Fever (FMF) is an inherited autoinflammatory disease. One of the feared complications of FMF, amyloidosis is often correlated with an increased mortality rate. The severity of the disease is linked with different mutations in the MEFV gene that may favor different outcomes (amyloidosis, Bechet's disease…). Although several countries worldwide contribute remarkably to research related to FMF, Arab countries make up only a small part of this contribution. This study aims to estimate numerically the contribution of the Arab world to research conducted on FMF. PubMed is used to quantitate the number of FMF-related articles published by each Arab country from 2004 till 2019. The retrieved numbers are normalized with respect to each country's average population and average Gross Domestic Product (GDP) and are also compared to those of some non-Arab countries having high FMF prevalence. In comparison with some non-Arab countries, the Arab world has a minor contribution of 3.80% to the total FMF-related publications, faced by 24.93% solely by Turkey. Out of total research done by Arab countries, FMF-related articles constitute no more than 0.133%. When normalized against the average population, Tunisia ranks first, followed by Lebanon. Similarly, normalizing the retrieved numbers of articles against average GDP shows that Tunisia and Lebanon come first and second, respectively. Only 8 Arab countries published a total of 13 articles concerning amyloidosis which makes 4.7% of the total Arabic FMF published articles. This study reflects an undoubtable need for more research to be conducted on FMF by the Arab countries, which suffer greatly from immense shortage in research productivity, due to the many obstacles and limitations these countries face every day.
