AB The  term  “spondyloarthritis”  is  used  to  describe  an  overlapping  group  of  diseases  that  are  characterized  by  inflammation  of  the  sacroiliac  joints  (sacroiliitis);  axial  spine  (spondylitis);  tendon,  fascia,  and  ligament  insertion  sites  (enthesitis);  and,  in  some  patients,  an  oligoarthritis,  rash,  or  inflammatory  eye  disease  (uveitis).  This  group  of  diseases  has  also  been  referred  to  as  seronegative  spondyloarthritis  based  on  the  absence  of  rheumatoid  factor.  These  diseases  include  ankylosing  spondylitis,  psoriatic  arthritis,  the  arthritis  of  inflammatory  bowel  disease,  and  reactive  arthritis.  Although  these  conditions  share  common  features,  each  one  has  distinct  clinical  and  epidemiologic  characteristics  (Table  17–1).  However,  in  some  patients,  especially  early  in  the  disease  presentation,  the  diagnosis  is  not  clear;  these  patients  are  considered  to  have  undifferentiated  spondyloarthritis.  The  overall  prevalence  of  these  conditions  has  been  estimated  to  be  between  0.5%  and  1.5%.
