The Chinese Spondyloarthritis Inception cohort (CESPIC) was started 2000 as a prospective, longitudinal, multicentre, nationwide study in China on patients with early SpA including ankylosing spondylitis (AS, also known as radiographic axial spondyloarthritis) and non-radiographic axial SpA. The objectives of CESPIC are to learn about the course of SpA during the very early stage of the disease, to appropriately assess the outcome including radiographic progression of patients after several years of follow-up, to identify outcome predictors, to assess quality of life, function, and costs (direct and indirect costs). CESPIC has been recently expanded to recruit patients with other forms of SpA / conditions associated with SpA: reactive arthritis, acute anterior uveitis, Crohn's disease as well as with psoriasis / axial psoriatic arthritis.
None
None
Patients included in CESPIC are required to have a definite clinical diagnosis of axial SpA / juvenile SpA (currently only adult patients with radiographic axial SpA = ankylosing spondylitis - AS are recruited) or a definite diagnosis of Crohn's disease or a definite diagnosis of acute anterior uveitis or a definite diagnosis of psoriatic arthritis with axial involvement or a definite diagnosis of reactive arthritis.

Treatment groupsSee each treatment group below.
BASDAI
The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) disease activity questionnaire contains six questions regarding subjective symptoms
ASDAS
The Ankylosing Spondylitis Disease Activity Score (ASDAS) is a new composite index to assess disease activity in Ankylosing Spondylitis (AS)1. It combines five disease activity variables with only partial overlap, resulting in one single score with better truth (validity), enhanced discriminative capacity and improved sensitivity to change as compared to single-item variables
CRP
A c-reactive protein test measures the level of c-reactive protein (CRP) in a sample of your blood. CRP is a protein that your liver makes. Normally, you have low levels of c-reactive protein in your blood. Your liver releases more CRP into your bloodstream if you have inflammation in your body. High levels of CRP may mean you have a serious health condition that causes inflammation.
BASMI
BASMI was created to help clinicians accurately assess axial status (through five measurements) of individuals suffering from Ankylosing Spondylitis. The measurements are then interpreted to derive a metrology index to define clinically significant changes in spinal mobility.
ASAS20
The ASAS Response Criteria (ASAS 20) is defined as an improvement of at least 20% and an absolute improvement of at least 10 units on a 0-100 scale in at least three of the following domains: Patient global assessment, Pain assessment, Function (BASFI), and Inflammation (last 2 questions of BASDAI).
ASAS40
The ASAS Response Criteria (ASAS 20) is defined as an improvement of at least 40% and an absolute improvement of at least 10 units on a 0-100 scale in at least three of the following domains: Patient global assessment, Pain assessment, Function (BASFI), and Inflammation (last 2 questions of BASDAI).
