Immune-Mediated Inner Ear Disease Associated with Type 1 Autoimmune Hepatitis: A Challenging Coexistence.

Autoimmune hepatitis (AIH) is characterized by elevated serum transaminase, increased immunoglobulin G levels, presence of autoantibodies, and hepatocellular damage. Coexistence with other autoimmune diseases has been reported in almost half of patients with AIH. Here, we report a 60-year-old man who developed rapidly progressive, bilateral, asymmetrical, and asynchronous sensorineural hearing loss that was consistent with immune-mediated inner ear disease (IMIED).

Serum levels, and bone marrow immunohistochemical expression of, vascular endothelial growth factor in patients with chronic myeloproliferative diseases.

Current data suggest that angiogenesis plays a significant role in the pathogenesis and progression of chronic myeloproliferative diseases (cMPDs). In the present study, we evaluated serum levels of vascular endothelial growth factor (VEGF) in 83 patients with cMPDs [myelofibrosis with myeloid metaplasia (MMM, n = 25), essential thrombocythaemia (ET, n = 40), polycythaemia vera (PV, n = 8) and chronic myeloid leukemia (CML, n = 10)] and in 27 healthy individuals. Serum VEGF levels were significantly increased in patients with cMPDs compared to healthy individuals (all p values were < or = 0.

Serum interleukin (IL)-1, IL-2, sIL-2Ra, IL-6 and thrombopoietin levels in patients with chronic myeloproliferative diseases.

A number of growth factors are involved in clonal haematopoietic expansion and their clinical significance in patients with chronic myeloproliferative diseases requires further evaluation. Using enzyme-linked immunosorbent assays, we analysed serum levels of interleukin (IL)-1a, IL-1b, IL-2, IL-6, the soluble IL-2 receptor alpha (sIL-2Ra), and thrombopoietin (TPO), in 25 individuals with myelofibrosis with myeloid metaplasia (MMM), 40 with essential thrombocythaemia (ET), eight with polycythaemia vera (PV), 10 patients with chronic myeloid leukaemia (CML) and 27 normal controls. These were correlated with clinicopathological characteristics including overall survival, and histopathological bone marrow features, including angiogenesis.
