4 calculators · JADAS, cJADAS, SLEDAI-2K
Here you will find pediatric calculators in rheumatology for measuring disease activity: the Juvenile Arthritis Disease Activity Score JADAS, which combines physician and patient global assessment, active joints (10, 27 or 71) and normalized ESR or CRP, the lab-free cJADAS with levels for cJADAS10 according to ACR 2021, and the SLEDAI-2K with 24 weighted descriptors of lupus activity (Gladman 2002). They are suitable for follow-up and documentation in juvenile arthritis and lupus. Each calculator states its formula and sources.

JADAS – Juvenile Arthritis Disease Activity Score
Physician and patient global assessment, active joints (10/27/71) and normalized ESR or CRP – activity levels according to ACR 2021 (JADAS10) or Consolaro (JADAS27) -
cJADAS – clinical JADAS
JADAS without laboratory value: physician and patient global assessment plus active joints – levels for cJADAS10 according to ACR 2021 or Consolaro 2014 -
SLEDAI-2K
24 weighted descriptors (8/4/2/1) of lupus activity in the last 10 days (Gladman 2002) -
Revised Jones Criteria 2015 / Jones criteria 2015 for acute rheumatic fever
Major and minor criteria of acute rheumatic fever according to AHA 2015, separately for populations at low and at moderate/high risk
Frequently asked questions
How do I calculate the JADAS in juvenile idiopathic arthritis?
The JADAS calculator combines physician and patient global assessment, the number of active joints (10, 27 or 71 joints) and the normalized ESR or CRP, and classifies the result into activity levels.
Is there a JADAS without a laboratory value?
Yes, the cJADAS (clinical JADAS) dispenses with the laboratory value and uses the physician and patient global assessments plus active joints. The calculator gives cut-offs for cJADAS10 according to ACR 2021.
How do I record lupus activity with the SLEDAI-2K?
The SLEDAI-2K calculator comprises 24 weighted descriptors (weights 8, 4, 2 and 1) of lupus activity over the last 10 days according to Gladman 2002. The sum of the weighted descriptors gives the SLEDAI-2K score.
