The CD68+/H-ferritin+ cells colonize the lymph nodes of the patients with adult onset Still's disease and are associated with increased extracellular…

Summary In this work, we aimed to evaluate the levels of ferritin enriched in H subunits (H-ferritin) and ferritin enriched in L subunits (L-ferritin) and the cells expressing these two molecules in the lymph node (LN) biopsies obtained from adult-onset Still's disease (AOSD) patients, and the possible correlation among these data and the severity of the disease. Ten patients with AOSD underwent LN biopsy. All the samples were stained by immunofluorescence. A statistical analysis was performed to estimate the possible correlation among both H-ferritin and L-ferritin tissue expression and the clinical picture of the disease. Furthermore, the same analysis was performed to evaluate the possib…
H-ferritin and proinflammatory cytokines are increased in the bone marrow of patients affected by macrophage activation syndrome
2017
Summary Macrophage activation syndrome (MAS) is hyperinflammatory life-threatening syndrome, associated typically with high levels of serum ferritin. This is an iron storage protein including heavy (H) and light (L) subunits, categorized on their molecular weight. The H-/L subunits ratio may be different in tissues, depending on the specific tissue and pathophysiological status. In this study, we analysed the bone marrow (BM) biopsies of adult MAS patients to assess the presence of: (i) H-ferritin and L-ferritin; (ii) CD68+/H-ferritin+ and CD68+/L-ferritin+; and (iii) interleukin (IL)-1β, tumour necrosis factor (TNF) and interferon (IFN)-γ. We also explored possible correlations of these re…
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…

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…
Influencia del tiempo de ligadura del cordón umbilical en la morbilidad secundaria neonatal y los depósitos de hierro en el neonato
2022
El déficit de hierro es el déficit nutricional más frecuente a nivel mundial y constituye un importante problema de salud pública, principalmente en los países más desfavorecidos. La causa más frecuente de anemia en el mundo es la deficiencia de hierro. Los períodos críticos donde los requerimientos son elevados son el primer año de vida, la adolescencia y el embarazo. El pinzamiento demorado aumenta los depósitos de hierro en los RN, que les garantiza una disponibilidad de este mineral durante los primeros meses de vida, periodo crucial del desarrollo de múltiples sistemas como el SNC. , pero también se le se asoció con un aumento de la policitemia neonatal, ictericia patológica con necesi…
