RA is more common in females
High proportion of RF positivity
Association with SE
Conflicting results of severity
Delay in initiation of therapy 1,2
Low use of DMARDS 1,2

Genetic studies of Rheumatoid Arthritis
in some Arab States
Introduction
Goal:
• Investigate the genetic basis of RA in the
Middle East by collecting at least 2000 RA and
2000 controls from 5 Rheumatology Centers
across 5 Arab States.
Genetic studies of Rheumatoid Arthritis
in some Arab States
Introduction
Goal:
– Genome Wide Association Study (GWAS) that will
test for >30 identified risk alleles identified in
European and North American populations
Objective of this Presentation

• 37% of our RA patients are on biologics
( in Europe 10-30% , in USA 40% )
Future Plans
Introduction
• Analyze the demographic and clinical data on
a regular basis
• Encourage more centers to join MERAC
