The reactive arthritis (Reiter’s syndrome) is an asymmetric, non septic inflammation of several joints, mainly of the lower limbs, associated with the occurrence of a change called "enthesitis" (inflammation of the tendon), and proceeded by an extraarticular manifestation and by infection of various microorganisms. Classically it includes the triad arthritis, urethritis, and conjunctivitis. App...

Reactive arthritis (ReA) is a non-purulent joint inflammation that usually follows bacterial gastrointenstinal or urogenital infections. The classic presentation of ReA is characterized by an asymmetric arthritis usually in the lower limbs associated with urethritis, conjunctivitis and occurrence of other articular or extra-articular manifestations. ReA is classified as a type of seronegative s...

■ In reactive arthritis (ReA), exposure of the host to infectious agents leads to the development of an inflammatory arthritis and other manifestations of systemic disease in the absence of an ongoing infectious process. ■ Approximately 50% of ReA and undifferentiated oligoarthritis cases can be attributed to a specific pathogen by a combination of culture and serology. The predominant organism...

Reactive arthritis is defined as arthritis that occurs during or after an extraarticular infection. It is mostly difficult to determine the causative agent that causes inflammation in the joints. Initially, salmonella, shigella, chlamydiaand yersinia were considered to be pathogenic agents. But recently, in addition to demonstrated viral and bacterial agents, there are also other cases of react...

The term “reactive arthritis” was first introducedby Aho et al. in 1973 for conditions following infection in other organs in which no microbial antigens could be isolated from the joint. Rheumatic fever, Reiter’s syndrome and postenteric reactive arthritis constitute the major clinical forms of the disease. A number of unrelated organisms have been implicated in association with the disease. T...

Yersinia specific immune complexes were demonstrated in the synovial fluid of three patients out of 12 with yersinia triggered reactive arthritis. They were not detectable in the synovial fluid of any of the 16 control patients, including nine with reactive arthritis triggered by factors other than yersiniae. Platelet reactive IgG was detectable in the synovial fluid of eight out of the 12 pati...

I is one of the important causes for the inflammation of the joint (arthritis). Microorganisms which include bacteria, viruses, fungi and parasites can cause arthritis, which can be acute or chronic. Acute arthritis is generally caused by pyogenic bacteria and termed as septic arthritis. Chronic arthritis is generally caused by mycobacteria and fungi. In reactive arthritis and other forms of sp...

OBJECTIVE To study HLA class II association in reactive arthritis. METHODS 63 patients with reactive arthritis and 46 with rheumatoid arthritis were included in the study. HLA-DR alleles were determined by using a sequence specific PCR method. Oligonucleotide hybridisation was used for definition of DRB1*04 subtypes and DQB1 alleles. HLA-B27 was determined by standard microcytotoxity test or ...
