Session Title: Miscellaneous Rheumatic and Inflammatory Diseases Poster I
Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
Background/Purpose: Yamaguchi’s criteria
for classification of adult-onset Still’s disease (AOSD) has been widely
applied in clinic despite it was established decades ago. However,
hyperferritinemia, which is a hallmark of AOSD, is not included in the
criteria. Moreover, the criteria require differential diagnosis of malignancy,
infection, etc., which has been challenging. Heme oxygenase (HO)-1 is
stress-inducible heme degrading enzyme highly expressed in monocyte/macrophage,
serum levels of which has been reported as a promising biomarker for AOSD.
We here report preliminary data on serum ferritin and HO-1 levels and AOSD
Methods: Under the Hypercytokinemia Study Group
collaboration, we collected sera from a total of 111 AOSD cases. Those patients
were further divided into active, remission, and relapse groups, based on their
clinical status. Other rheumatic diseases such as ANCA-associated
vasculitis, and culture-positive sepsis were included as disease controls.
Serum ferritin and HO-1 levels were measured in all of the collected samples by
means of ELISA. An association among clinical symptoms, serum ferritin, and
HO-1 was explored.
Results: Serum ferritin and HO-1 levels
were significantly higher in active and relapsed AOSD cases compared to disease
controls, and were reduced by the treatment. Although significant
correlation between serum ferritin and HO-1 levels were observed, there were
some discrepancies. After remission-induction therapy, 72.2% of the patients’ serum
ferritin levels were normalized, but 61.1% of them had high serum HO-1 levels
(>13.8 ng/ml). Moreover, 31% of patients in remission exhibited high HO-1
levels, but high ferritin levels were observed only in 6.9% of the patients
Conclusion: We confirmed that serum
ferritin and HO-1 serve as a biomarker for AOSD. Characterization of serum ferritin
and HO-1 levels in AOSD disease status merit further investigation. By
enrolling more cases and disease controls, we plan to determine use of ferritin
and HO-1 for the diagnosis of AOSD (UMIN000012912).
