Association Between Memory B-Cells and Clinical and Immunological Features of P...
Barcelos, F; Martins, C; Papoila, A; Geraldes, C; Cardigos, J; Nunes, G; Lopes, T; Alves, N; Vaz-Patto, J; Branco, J; Borrego, LMB-cells play a pivotal role in primary Sjögren's syndrome (pSS) pathogenesis. We aim to (1) evaluate the distribution of B-lymphocyte subpopulations in pSS and Sicca patients, (2) establish cut-off points that discriminate pSS from controls, (3) evaluate the association between memory B-cells and phenotypic features in pSS. We included 57 pSS patients, 68 Sicca and 24 healthy controls. Circulating B-cells were ...
Lenalidomide is effective and safe for the treatment of patients with relapsed ...
João, C; Freitas, J; Gomes, F; Geraldes, C; Coelho, I; Neves, M; Lúcio, P; Esteves, S; Esteves, GPatients with multiple myeloma (MM) and severe renal impairment (SRI) have shorter survival than MM patients without renal failure. Although lenalidomide is a highly active drug, this immunomodulatory agent is frequently neglected in this context due to its predominant renal clearance and, consequently, an increased risk of toxicity. This risk might be overcome with the proper lenalidomide dose adjustment to re...
Aberrant p15, p16, p53, and DAPK Gene Methylation in Myelomagenesis: Clinical a...
Geraldes, C; Gonçalves, AC; Cortesão, E; Pereira, MI; Roque, A; Paiva, A; Ribeiro, L; Nascimento-Costa, JM; Sarmento-Ribeiro, ABBACKGROUND: Aberrant DNA methylation is considered a crucial mechanism in the pathogenesis of monoclonal gammopathies. We aimed to investigate the contribution of hypermethylation of 4 tumor suppressor genes to the multistep process of myelomagenesis. METHODS: The methylation status of p15, p16, p53, and DAPK genes was evaluated in bone marrow samples from 94 patients at diagnosis: monoclonal gammopathy of unce...
