International Palindromic Rheumatism Society

The International Palindromic Rheumatism Society (IPRS) is a non-profit, voluntary organization whose mission is to help inform, give advice to, and offer a place of support to people affected by palindromic rheumatism (PR). Their goal is to have every physician aware of PR and give every sufferer of PR access to an online support and advice group. PR, also known as Hench-Rosenberg syndrome or Hench�s syndrome, is a form of an autoimmune disorder that is a rare type of inflammatory arthritis. PR is characterized by sudden and recurrent attacks of painful swelling of the joints and surrounding tissues. Attacks may last for several days or just a few hours. Between attacks, pain and swelling completely disappear.
