Session Information
Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
Background/Purpose:
Widely
accepted outcome measures for disease activity and severity at Adult Onset
Still’s Disease (AOSD) is not developed until now. Predictive factors for worse
prognosis, such as response to initial treatment or life-threatening
complications are also not clearly defined Yamaguchi criteria is routinely
used for AOSD diagnosis which include 4 major and 4 minor criteria, reflecting
almost whole essential AOSD features. These essential features might also be
associated with disease severity and the objective of this study was to assess the
relationship of arithmetic count of Yamaguchi criteria with clinical,
laboratory features and treatment choice.
Methods: At
2012, 19 rheumatology centers collected data on clinical features
(demographics, fever, rash, arthralgia, arthritis, myalgia, sore-throat,
lymphadenopathy, hepatomegaly, splenomegaly, pleuritis, pericarditis and
rare findings including macrophage activation syndrome) laboratory features
(complete blood count, neutrophil percentage, ferritin, erythrocyte
sedimentation rate, C-reactive protein (CRP), AST, ALT, ALP, GGT, LDH,
bilirubin, albumin, triglyceride, total cholesterol, HDL-cholesterol,
LDL-cholesterol), treatment choices and disease course, retrospectively.
Overall 356 patients were enrolled and 269 of 356 patients were available for
further analysis. Yamaguchi items were added arithmetically. Total Yamaguchi
scores were between 5 to 8. At the end of statistical analysis, a cut-off of 7
or more score is chosen.
Results: Overall,
269 (56.1% female) patients were assessed. Mean age was 38.5 (14.5) years and
mean diagnosis age was 34.9 (14.5) years. Total Yamaguchi score ≥ 7 was present
in 83 (30.9%) patients. Hepatomegaly and serositis were found more frequently
at Yamaguchi score ≥ 7. Essential laboratory activity parameters, such as
ferritin and CRP were also related with high Yamaguchi scores. There was a
difference at treatment choices that physicians started higher dosage of corticosteroids
with more frequent methotrexate use (Table).
Conclusion:
Higher Yamaguchi scores may be one of the criteria for higher disease activity
and severity in AOSD. We suggest that clinical features, level of acute phase
reactant/ferritin and treatment choices are affected from disease load.
