MR 17 May 2010

Impromptu teaching rounds for me this AM.  Complex case involving a hispanic female with a pain flare in multiple joints, recent prolonged travel in Mexico complicated by diarrhea, and a history of unexplained iron deficiency anemia.  Important turning point in this case was measurement of ESR of >115.  XRAY of spine and pelvis revealed fused SI joints and enthesopathic changes of the vertebra consistent with ankylosing spondylitis vs enteropathic arthropathy.

Seronegative spondyloarthropathy:  constellation of diseases that include ankylosing spondylitis, reactive arthritis (Reiter's), psoriatic arthritis, enteropathic arthritis, and undifferentiated spondys.  These diseases are often associated with HLA-B27.  Enteropathic arthritis can be associated with a variety of infections to include traveler's diarrhea and brucellosis.  IBD associated spondy can preceed onset of bowel symptoms by months / years.  Treatment of these disease ranges from anti-inflammatories, corticosteroids, to TNF alph inhibitors.
