- The aims of this study were to assess long-term immunity and reimmunization responses against tetanus toxoid in recipients of autologous stem cell grafts and to compare immune status in patients who underwent ABMT or autologous blood stem cell transplantation (APBSCT). Ninety patients were included in the study; 52 had received ABMT and 38 APBSCT. Thirty of 52 ABMT patients (58%) and 25 of 38 APBSCT patients (66%) had protective antibody levels against tetanus before transplantation (P = NS). The rate of seropositivity had decreased at 1 year after transplantation; 15 of 52 (29%) ABMT patients and 18 of 38 (47%) APBSCT patients (P = NS) were still positive after 1 year. There were no cases of spontaneous recovery in seronegative patients. Most patients were reimmunized with three doses of tetanus toxoid given at 12, 13, 14 and or 18 months after transplantation. All immunized patients had protective immunity against tetanus at 1 year after vaccination. These results suggest that humoral immunity is defective both after ABMT and after APBSCT and in both cases the loss of immunity seems to be similar. Reimmunization of patients who have undergone ABMT or APBSCT is necessary to obtain protective immunity against tetanus.

- Fifteen allogeneic BMT patients in a phase II study were given foscarnet 60 mg/kg twice daily for 14 days as pre-emptive therapy against CMV disease. CMV infection was diagnosed by a leukocyte-based nested PCR. All 15 patients were evaluable for toxicity. One patient did not fulfill the inclusion criteria of two consecutively positive CMV PCR tests and therefore was not evaluable for efficacy. Thus, 14 of 15 patients were evaluable for development of CMV disease. None of the patients developed CMV disease and all 14 assessable patients had a negative CMV isolation at the end of therapy. None of the 15 patients had to discontinue therapy due to toxicity. Six patients reported mild gastrointestinal disturbances, three patients headaches, and three patients mild urethritis or hemorrhagic cystitis. Serum-electrolyte disturbances were common including abnormal magnesium, potassium and calcium levels. Two patients developed mild serum-creatinine increases requiring adjustment of the foscarnet dosage according to protocol. We conclude that a dosage of foscarnet of 60 mg/kg given twice daily seems to be safe and effective in preventing CMV disease in allogeneic BMT recipients. A study comparing foscarnet and ganciclovir is indicated.
