The aim of this study was to evaluate taste perception, salivary flow rate and oral pathologies in three different groups of patients undergoing hematopoietic SCT (HSCT) classified according to time post transplant. Group I (n ¼ 20) up to 150 days after HSCT, group II (n ¼ 20) between 151 and 1095 days and group III (n ¼ 21) more than 1095 days. Taste acuity was measured by four basic tastes of four solutions, in three concentrations (M): NaCl, sucrose, citric acid and caffeine. Patients classified flavors as sweet, sour, salty, bitter and without flavor. The intensity was considered high, medium and low. Unstimulated saliva was collected and salivary flow rates (ml/min) were determined. Of 61 patients, 31 had chronic GVHD. For the sweet solution, the high and low concentrations represented a challenge for those patients. No patients were sensitive to the low concentration of caffeine solution (P ¼ 0.05). Saliva flow rate was diminished in 10 of 61 (16%) patients and hyposalivation was more intense in groups II/III (P ¼ 0.007). There was no correlation between taste dysfunction and oral chronic GVHD. The results indicated taste alterations only for the sweet and salty tastes even in patients up to 3 years after HSCT and may not correlate with oral chronic GVHD and with hyposalivation.
Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system. Its treatment has focused on inflammation control as early as possible to avoid disability. Autologous hematopoietic stem cell transplantation (AHSCT) has been used for treating MS since 1996, with recent decisive results regarding benefits in long-term efficacy. Five patients followed up at an MS center in Belo Horizonte, Brazil, who had relapsing-remitting MS with high disease activity, underwent AHSCT between 2009 and 2011. They were evaluated clinically, with magnetic resonance imaging, and by the EDSS every six months after transplantation, up to July 2018. The patients were four women and one man, with ages ranging from 25-50 years, and time since disease onset ranging from 4-17 years at the time of the procedure. Four patients improved, one patient was stabilized, and all patients were free of disease activity after 5-9 years. Through improving patient selection and decreasing the time from disease onset, AHSCT could stop epitope spreading and disease progression. Despite multiple other therapeutic choices being approved for relapsing-remitting MS, AHSCT continues to be a treatment to consider for aggressive MS disease.
