Ben Zvi et al. [
5] from the Sheba Medical Center have conducted the first randomized placebo-controlled trial of anakinra in colchicine-resistant familial Mediterranean fever (FMF) showing that the interleukin (IL)-1 receptor antagonist is useful in reducing attack frequency and improving the quality of life in patients with colchicine-resistant FMF.
These authors have also collaborated with colleagues from Turkey and Italy [
6] in defining a severity score for FMF which will serve as a useful tool in assessing the utility of therapeutic interventions in clinical trials in both children and adults.
Moving on from FMF to other rheumatic diseases, Ofer-Shiber and Molad at the Rabin Medical Center in Petach-Tikva reported that a C-reactive peptide (CRP) level ≥0.9 mg/dl at diagnosis in patients with psoriatic arthritis predicted an earlier need for tumor necrosis factor (TNF) blockers in order to achieve disease control [
7]. The role of vitamin D in systemic lupus erythematosus (SLE) has been investigated at the Sheba Medical Center showing, among other things, a higher incidence of hypocalcemic events among SLE patients in comparison with controls. Colafrancesco et al. have recently reported an association between ‘autoimmune/inflammatory syndrome induced by adjuvant’ (ASIA) and Sjogren’s syndrome on top of an overlap in some clinical manifestations such as dry mouth and dry eyes [
8]. The group led by Amital and colleagues used “big data” analysis to investigate the association between comorbidities and how medical interventions affect outcomes over time [

10].
In Tel-Aviv, at the Sourasky Medical Center, Ablin et al. reported that magnetic resonance imaging (MRI) findings consistent with sacroiliitis were found among a significant proportion of patients diagnosed with primary fibromyalgia [
11]. The same group described the use of induced sputum analysis in patients diagnosed with systemic sclerosis showing changes in cellular pattern and correlation with relevant clinical and pulmonary function parameters. At the Soroka Medical Center in Beer-Sheva, Abu-Shakra found no association between SLE disease activity and depression [
12].
At the Rambam Medical Center in Haifa, Balbir and collaborators from the EUSTAR group observed that, in patients with systemic sclerosis that present early after the onset of Raynaud’s phenomenon, the manifestation of 50% of all incident organs occurs within 2 years simultaneously, rather than sequentially [
13].
Zisman, from the Carmel Medical Center in Haifa, reported the risk of herpes zoster was significantly increased with age, treatment with steroids, and combination of antiTNF-α agents and c-DMARDs, but not with c-DMARDs or antiTNF-α therapy alone in patients with psoriatic arthritis [
14]. Mader et al. from the Ha’emek Medical Center in Afula have shown the utility of musculoskeletal ultrasound in identifying entheseal changes in diffuse idiopathic skeletal hyperostosis (DISH) [
15].
Shaare-Zedek Medical Center researchers, in collaboration with the Hadassah Medical Center investigators, have demonstrated lower overall incidence rates of vasculitis among the Jewish population despite rising incidence rates of granulomatosis with polyangiitis and microscopic polyangiitis [
16]. In the same center, Mevorach et al. have demonstrated the utility, safety, and efficacy of eculizumab in pediatric patients with recurrent acute, predominantly motor demyelinating neuropathy with conduction block, and chronic hemolysis attributed to p.Cys89Tyr mutation in the CD59 gene [

Other Middle East countries
Generally, there is quantitative and qualitative improvement in rheumatology research produced from these countries in the last five decades, as well as collaborative research work between countries within the region [
18]. We have retrieved 76,146 papers from the National Library of Medicine’s (NLM) MeSH database in rheumatology between 1997 and 2017. Of those, 4513 (5.9%) were published from these countries. Turkey has contributed 1947 papers, 43% of the papers derived from Middle East countries. On the other hand, some countries, such as Yemen, did not produce any paper over the last two decades.
The differences between Middle Eastern countries in the published research can be attributed to the number of rheumatologists and the number of academic institutes within a country, political stability, the availability of funds, research facilities, an appropriate environment to conduct research, and the incentives for research.
In the last decade, governments in the Middle East have created research grants and awards to facilitate research. Pharmaceutical industries are vital partners in this transformation by spreading research skills among Middle East rheumatologists and providing funds for research. Furthermore, healthcare systems in Middle Eastern countries have an important role to play in promoting research culture, allocating time and incentive for those involved in research. Needless to say, it is important to mention that optimizing collaborative research projects between Middle Eastern countries will help in producing high-quality research from the region [
