Vaccination against tick-borne encephalitis (TBE) after autologous and allogeneic stem cell transplantation.

INTRODUCTION: Our aim was to assess response and side effects of 4 doses of TBE vaccine to patients (pts) after allo- and autologous stem cell transplantation (SCT). PATIENTS: Included were 104 pts with leukaemia, myeloma and lymphoma, median age 61 yrs. METHODS: Vaccine (FSME-Immun®) was given at 9, 10, 12, and 21 months post-transplant. Serum samples were obtained before and after vaccinations. Healthy controls (n = 27) received 3 vaccinations. Assessments of TBE specific IgG antibodies were performed by Enzygnost anti-TBE ELISA test (Siemens, Sweden). RESULTS: Antibody levels (>12 U/mL; "seropositivity") were seen in 77% and 80% of pts after allo- and autoSCT; IgG levels; 89 vs 94 U/mL. Ongoing chronic GvHD and immunosuppression (n = 29) was associated with sero-negativity in the last sample (p = 0.007). All controls (n = 27) developed protective antibody levels. CONCLUSIONS: TBE vaccination was safe, and 4 doses starting 9 months post-SCT, induced seropositivity in a vast majority of pts.

Patients with polycythemia vera have worst impairment of quality of life among patients with newly diagnosed myeloproliferative neoplasms.

The quality of life (QoL) at the time of diagnosis of myeloproliferative neoplasm (MPN) has, to date, not been studied. One hundred and seventy-nine patients with MPN: 80 with essential thrombocythemia (ET), 73 with polycythemia vera (PV), 22 with primary myelofibrosis (PMF) and four with MPN undifferentiated, were included in this study. European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQC30) and the MPN-Symptom Assessment Form (MPN-SAF) were used to evaluate QoL. Fatigue was the most reported symptom in these patients. Patients with PV reported significantly higher mean scores for inactivity, dizziness, cough, itching, depression and lower total QoL compared to patients with ET. Patients with PV had significantly more headache and itching compared to patients with PMF. When the newly diagnosed patients with MPN were compared with a cohort of patients with MPN with mean disease duration of 7.8 years, the differences were most striking for patients with PMF, with significantly more fatigue, abdominal discomfort, concentration problems, insomnia, fever, weight loss and lower overall QoL developed over time.

Working memory training for patients with acquired brain injury: effects in daily life.

OBJECTIVE: Working memory deficits are common after brain injury and cause multiple problems for patients in daily life. Research has shown that it is possible to improve working memory functioning by training. The aim of this study was to examine whether patients with moderate to severe cognitive deficits after brain injury could profit from working memory training and if that training had any impact on their daily life activities. A training programme was designed consisting of computerized training software (Cogmed QM), coaching, education, and peer support. The design was a prospective cohort study in a naturalistic setting at an outpatient centre for persons with acquired brain injury. METHODS: Participants were 18 patients, aged 17-64, who had difficulties in daily life pertaining to working memory deficits. Data were collected pre- and post-training and at a six-month follow-up. RESULTS: Despite relatively severe cognitive deficits patients were able to carry out a demanding training programme with positive results. The computerized training showed a significant improvement on trained working memory tasks. Patients starting at a low training level improved the most. Self-rating measurements and interviews indicated that patients experienced fewer cognitive problems in daily life after training. The effect was maintained at the six month follow-up. Training results were not affected by age or time post-injury (1-22 years).

The effects of hydroxyurea on PRV-1 expression in patients with essential thrombocythemia and polycythemia vera.

The study was designed to investigate the influence of hydroxyurea (HU) treatment on PRV-1 expression. Eighteen newly diagnosed patients with essential thrombocythemia (ET) or polycythemia vera (PV) were included. HU significantly increased PRV-1 gene expression in the early stage of treatment.
