Chikungunya (CKG) is an arthritogenic mosquito-transmitted alphavirus that manifests itself as a febrile illness and often progresses to severe and incapacitating polyarthralgia (1). Several reports have demonstrated persistent polyarthritis akin to seronegative peripheral arthropathy (2). However, to our knowledge, imaging-confirmed axial disease has not been described in this context. We repo...

Enthesopathy at the superior or inferior surface of a calcaneus may be seen in normal individuals having degenerative osteoarthrosis. This condition is also known to occur in patients with rheumatoid arthritis, seronegative spondyloarthropathy, trauma, as well as inflammatory and metabolic diseases. Enthesopathy may sometimes be the first manifestation of a variety of rheumatic diseases. In thi...

Familial Mediterranean fever (FMF) is an autoinflammatory disorder characterized by recurrent febrile polyserositis and arthritis attacks. Accompanying seronegative spondyloarthropathy has been reported in FMF in addition to its own joint involvement. However, the coexistence of FMF with juvenile idiopathic arthritis (JIA) is very rare, only three cases with severe joint involvement and mortal ...

the pelvis and lumbar spine. Although the spondyloarthropathies are grouped together, they display distinct clinical features. It is likely that an interplay among genetic, environmental, and immunologic factors is responsible for the various clinical manifestations of these diseases. Infection with an unknown organism or exposure to an unknown antigen in a genetically susceptible patient (HLA-...

The case is reported of a 42 year old white woman meeting currently used diagnostic criteria for both ankylosing spondylitis and systemic lupus erythematosus (SLE). As found in a previously described similar case of a black man, HLA typing showed antigens associated with both SLE and seronegative spondyloarthropathy. This case thus supports the hypothesis that the two diseases occur together on...
