 Rheumatoid Arthritis 

Welcome to D&H National Research Centers, where we invite you to be a part of groundbreaking research that aims to improve the lives of individuals living with Rheumatoid Arthritis and get up $800 Compensation.

Rheumatoid Arthritis (RA) is a chronic autoimmune disorder that primarily affects the joints. In this condition, the immune system, which is meant to protect the body from foreign invaders like bacteria and viruses, mistakenly attacks the synovium—the lining of the membranes that surround the joints. This immune system response results in inflammation that can lead to joint damage, pain, and swelling.
