INTRODUCTION Although natural autoantibodies make up the majority of circulating immunoglobulins and are also present in high numbers in therapeutically used intravenous immunoglobulin preparations, they have received little attention and their precise role remains largely unknown. An increasing awareness of the importance of posttranslational autoantigen modifications and glycobiology led us t...

Certain microbes like yersinia, salmonella, shigella, campylobacter, chlamydia, and possibly gonococcus can trigger reactive arthritis especially in patients of the HLA-B27 type. In the present study we have used serological and culture methods to identify the probable triggering infection in 50 consecutive HLA-B27 positive patients diagnosed as having reactive arthritis. The two most common tr...

rheumatoid arthritis is a disease associated with painful joints that affects approximately 1% of the population worldwide, and for which no effective cure is available. it is characterized by chronic joint inflammation and variable degrees of bone and cartilage erosion. oxygen metabolism has an important role in the pathogenesis of rheumatoid arthritis. reactive oxygen species (ros) are produc...

Inflammatory arthritides developing after a distant infection have so far been called reactive or postinfectious, quite often depending on the microbial trigger and/or HLA-B27 status of the patient. For clarity, it is proposed that they all should be called reactive arthritis, which, according to the trigger, occurs as an HLA-B27 associated or non-associated form. In addition to the causative a...

Reiter's syndrome is an eponym used to denote the triad of arthritis, urethritis and conjunctivitis. This syndrome is named after Hans Conrad Julius Reiter, who was involved in the activities of the Nazi Racial Hygiene Program related to involuntary sterilization, euthanasia and criminal research projects. Reiter defamed the entire medical profession and it was therefore suggested that the term...

Collagen II (CII)-induced arthritis in DBA/1j mice is mediated by both CII-reactive T cells and anti-CII Ab-producing B cells. To determine the relative role of these processes in the development of arthritis, we specifically eliminated CII-reactive T cells by treating the mice with CII-pulsed syngeneic macrophages that had been transfected with a binary adenovirus system. These macrophages exp...

The reactive arthritis (ReA) is an autoimmune disorder usually induced by the prior infection. Conjunctivitis, urethritis and arthritis emerging after the prior onset of diarrhea were first described by Stoll in 1776. In 1818, Benjamin Brodie described 5 cases of conjunctivitis, urethritis and arthritis with a history of venereal diseases. In 1916, Fiessinger and Leroy described 4 patients with...

Reactive arthritis is a seronegative, HLA-B27-linked spondyloarthropathy which occurs as a result of a pathogen, often of gastrointestinal or genitourinary origin, and triggers a cell-mediated immune response. In this article, we present a 64-yearold male case who developed reactive arthritis with fever and asymmetric oligoarthritis ...

An ongoing outbreak of lymphogranuloma venereum (LGV) L2b proctitis, predominantly in HIV-positive men who have sex with men (MSM), has been reported in industrialised countries. A case of reactive arthritis after L2b proctitis is described. This case expands the spectrum of severe complications related to LGV L2b proctitis. Since this infection may be asymptomatic, this organism should be scre...

Background: Autoimmune disorders (AID) are emerging non-communicable diseases and understanding their epidemiology could reveal information about their clinical characteristics and disease management. Objective: To record the different types of arthritis cases attending a tertiary care center and study the profile of rheumatoid arthritis cases. Methods: The different types of arthritis cases re...
