Arthritis and running

Congratulations to our patients, some of whom could not walk last year who ran the Standard Chartered 10 k race in Dubai this year!

A cure for Rheumatoid Arthritis? Posted from Dubai. UAE

A researcher from Northwestern University Feinberg School of Medicine has invented a novel way to halt and even reverse rheumatoid arthritis. He developed an imitation of a suicide molecule that floats undetected into overactive immune cells responsible for the disease.


Whimsically referred to as Casper the Ghost, the stealthy molecule causes the immune cells to self-destruct.

The approach, tested on mice, doesn't carry the health risks of current treatments.

"This new therapy stopped the disease cold in 75 percent of the mice," reported Harris Perlman, the lead author and an associate professor of medicine at Feinberg. "The best part was we didn't see any toxicity. This has a lot of potential for creating an entirely new treatment for rheumatoid arthritis."

The study will be published in the February issue of Arthritis & Rheumatism.

Healthy immune cells are supposed to die after they attack an invading virus or bacteria. But in rheumatoid arthritis, the immune cells called macrophages live and go rogue. They proliferate in the blood, build up in the joints and invade cartilage and bone. Currently, there is no effective, nontoxic way to stop them.

Perlman discovered that immune cells in rheumatoid arthritis are low in a critical molecule called Bim, whose job is to order the cells to self-destruct. To correct that shortage, Perlman developed an imitation of the molecule, called BH3 mimetic. When Harris injected his drug into mice with rheumatoid arthritis, it floated ghostlike into their macrophages and bam!, the misbehaving immune cells self destructed.

In his research, Harris showed the molecule could prevent the development of rheumatoid arthritis as well as trigger a remission of existing disease. After the drug was injected in animals with the disease, joint swelling was reduced and bone destruction decreased.

Current treatments for rheumatoid arthritis include low-level chemotherapy and steroids. These are not always effective, however, and they are frequently accompanied by side effects. A newer class of therapy, which is sometimes used in combination with chemotherapy and steroids, is biologic response modifiers. These are antibodies or other proteins that reduce the inflammation produced by the hyperactive immune cells. These biologics don't work for everyone, though, and can be associated with side effects including the risk of infection.

Perlman said the next step is to develop nanotechnology for a more precise method of delivering the drug. His research was supported by the National Institute of Arthritis, Musculoskeletal and Skin Diseases and the National Institute of Allergy and Infectious Disease.

Rheumatology conference 2010

The Emirates Society of Rheumatology (ESR) in conjunction with the producers of Arab Health are pleased to announce the third Emirates Rheumatology conference in Dubai on 10.10.10. This now independent event aims to bring cutting edge information about rheumatic diseases once more to the region. Rheumatoid arthritis and other connective tissue diseases are a leading cause of disability around the world. Through better management of these conditions by Rheumatologists, Orthopedic Doctors, Family doctors and Internists the burden of these diseases will be reduced for patients and their families.

Awards for presentations Best Investigator and Best Young Investigator in the field of Rheumatology will be given again at this year’s conference. Abstracts will be considered from doctors and researchers in the region.

Keeping with tradition, this unique conference will focus on small group sessions, workshops, hands-on training and bring a special emphasis on the most pressing problems facing the region.
