Linking autoantibody production to bone loss

in rheumatoid arthritis

Inflammation of the synovium in a joint affected by rheumatoid arthritis

Autoantibodies against citrullinated proteins (ACPA) are found in people with rheumatoid arthritis and are one of the strongest risk factors for bone destruction in this disease. A recent study now directly links the formation of antibodies binding to mutated citrullinated vimentin (anti-MCV) to bone loss in rheumatoid arthritis, indicating that these autoantibodies act on osteoclasts, the bone cells responsible for bone resorption.

The research of  U. Harre, G. Schett and their coworkers provides fundamental new insights into the interaction between bone and the immune system in the inflammatory process leading to the development of rheumatoid arthritis.

Anti-CCP hs (high sensitive)®: a new biomarker for the serological diagnosis of early rheumatoid arthritis

ACPA for RA diagnosticsTimely diagnosis is of critical importance to the progression of rheumatoid arthritis (RA) because the rapid implementation of intensive treatment can inhibit damage to the joints and maintain function. In conjunction with medical history, clinical examination, and imaging procedures, serological tests form the foundation for an early diagnosis.

In addition to rheumatoid factors, autoantibodies against citrullinated antigens (ACPA) have proven to be valuable tools for the serological diagnosis of early RA. They have become a critical component of the new 2010 ACR criteria for the classification of RA, and account for three of the six points required to verify a diagnosis of RA. (more…)

Research Update: Prognosis of Outcomes for Rheumatoid Arthritis – What are the Risk Factors?

In the past, it has only been possible to explain some of the joint damage caused by rheumatoid arthritis (RA) based on known risk factors. In order to improve treatment for RA, future approaches to treatment will increasingly need to be tailored to individual patients and individually configured.

 

Personalized medicine in RA treatment

The goal is to develop individual treatments tailored to the needs of the individual patient, “personalized medicine” for rheumatoid arthritis diagnosis and treament (for more on the subject of personalized medicine, refer to the background article Early Detection and Personalised Medicine – What Biomarkers Tell Us on our rheumachec homepage).
