H-ferritin and CD68+/H-ferritin+ monocytes/macrophages are increased in the skin of adult-onset Still's disease patients and correlate with the multi-visceral involvement of the disease
Summary Adult-onset Still's disease (AOSD) patients may show an evanescent salmon-pink erythema appearing during febrile attacks and reducing without fever. Some patients may experience this eruption for many weeks. During AOSD, exceptionally high serum levels of ferritin may be observed; it is an iron storage protein composed of 24 subunits, heavy (H) subunits and light (L) subunits. The ferritin enriched in L subunits (L-ferritin) and the ferritin enriched in H subunits (H-ferritin) may be observed in different tissues. In this work, we aimed to investigate the skin expression of both H-and L-ferritin and the number of macrophages expressing these molecules from AOSD patients with persist…
AB0919 H-Ferritin and CD68+/H-ferritin+ Cells Are Increased in The Skin of Adult Onset Still's Disease Patients and Correlate with The Disease Activity
Background Adult onset Still9s disease (AOSD) is an inflammatory disease, characterized by high spiking fevers, arthritis, salmon-pink erythema and multivisceral involvement [1]. During AOSD, exceptionally high serum levels of ferritin may be observed and they might contribute to production of proinflammatory molecules [2]. Ferritin is composed by 24 subunits, heavy (H) subunits and light (L) subunits. The ferritin enriched in L subunits (L-ferritin) and the ferritin enriched in H subunits (H-ferritin) may be recognized in different tissues [3]. Objectives To investigate the skin tissue expression of both H-and L-ferritin and the number of macrophages expressing these molecules, in the infl…
