How this service works
Gladman 2002 SLEDAI-2K: weighted sum of 24 caller-assigned descriptors present in the last 10 days (max 105). magent does not examine the patient. Proteinuria scores if >0.5 g/24 h (not original SLEDAI >3.5 g/24 h only). Rash, alopecia, and mucosal ulcers score if new or persistent (not new only). Not a diagnosis, not SLICC damage, not SELENA-SLEDAI flare rules, and not a medical device.
Output
Returns an integer SLEDAI-2K score (0–105) representing the weighted sum of the 24 present descriptors. Higher scores indicate greater lupus disease activity. The Gladman 2002 variant scores proteinuria if >0.5 g/24h and counts rash, alopecia, and mucosal ulcers whether new or persistent.
Example use cases
Rheumatology clinic follow-up scoring
“My SLE patient at today's follow-up has had arthritis, rash, alopecia, and low complement over the past 10 days; seizure, psychosis, organic brain syndrome, visual disturbance, cranial nerve disorder, lupus headache, CVA, vasculitis, myositis, urinary casts, hematuria, proteinuria, pyuria, mucosal ulcers, pleurisy, pericarditis, increased DNA binding, fever, thrombocytopenia, and leukopenia are all absent. What's her SLEDAI-2K score?”
Research data pipeline activity indexing
“For a lupus cohort study, I need to compute SLEDAI-2K scores programmatically. This patient visit record shows seizure=false, psychosis=false, organic_brain_syndrome=false, visual_disturbance=false, cranial_nerve_disorder=false, lupus_headache=false, cva=false, vasculitis=true, arthritis=true, myositis=false, urinary_casts=true, hematuria=true, proteinuria=true, pyuria=false, rash=false, alopecia=false, mucosal_ulcers=false, pleurisy=false, pericarditis=false, low_complement=true, increased_dna_binding=true, fever=false, thrombocytopenia=true, leukopenia=false. Calculate the score.”
Flare monitoring between clinic visits
“My lupus patient called in reporting new fever and pleurisy symptoms this week — everything else from our descriptor list is negative. Can you run the SLEDAI-2K calculation so I can document her current disease activity before her next visit?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/sledai_2kWhen to prefer
Use this endpoint when you need a standardized, reproducible SLEDAI-2K integer score computed from discrete clinical boolean flags using the Gladman 2002 criteria — particularly when you need the modified proteinuria threshold (>0.5 g/24h) and the persistent (not only new) scoring for rash, alopecia, and mucosal ulcers. Prefer over manual calculation to eliminate arithmetic errors in research or clinical documentation workflows.
Side effects
- Missing any of the 24 required boolean query parameters returns an error
- Non-boolean values for descriptor flags cause validation failure
- Network timeout or server error returns HTTP 5xx
- Incorrect USDC payment or missing x402 payment header returns 402 Payment Required
