Table 1 Parameters for disease activity in rheumatoid arthritis, inflammatory bowel disease and psoriasis

From: Gender and the treatment of immune-mediated chronic inflammatory diseases: rheumatoid arthritis, inflammatory bowel disease and psoriasis: an observational study

Measurement Definition
Rheumatoid arthritis
   Swollen joint count (SJC) Number of swollen joints as determined by the physician out of a standard set of 28 joints
   Tender joint count (TJC) Number of joints tender to palpation (as for SJC)
   Patient assessment of pain Measured by 100 mm visual analog scale (VAS)
   Patient assessment of global disease activity Measured by 100 mm VAS
   Physician assessment of global disease activity Measured on a six-point scale ranging from 'no activity' to 'maximum activity'
   Acute phase reactant ESR (mm/h) and/or CRP (mg/l)
   Health Assessment questionnaire (HAQ) Assessment of functional status (0 to 3 points)
   EuroQol five dimensions utility score (EQ-5D) Assessment of health-related quality of life (HRQOL) (0 to 1)
   Disease Activity Score (DAS28) Assessment of disease activity computed using SJC, TJC, ESR and patient assessment of global disease activity, based on 28 joints. Termed DAS28-CRP when CRP is used instead of ESR
Inflammatory bowel disease
   Hemoglobin level Measure in g/l
   Acute phase reactant ESR (mm/h) and/or CRP (mg/l)
   Harvey Bradshaw Index (HBI) Assessment of disease activity completed by both patient and physician
   Short Health Scale (SHS) Assessment of HRQOL in four domains, measured by 100 mm VAS
   Psoriasis Area and Severity Index (PASI) Assessment of extent and severity of skin lesions consisting of four components; scaling, redness, extent and elevation (0 to 72 points)
   Dermatology Life Quality Index (DLQI) Assessment of the effect of skin disease on HRQOL (0 to 30 points)
  1. ESR, erythrocyte sedimentation rate; CRP, C-reactive protein
