Late CMV disease remains a major concern in allogeneic BMT recipients. Few surveillance data are available on the occurrence of CMV infection and recurrences after day +100. We evaluated the occurrence of antigenemia (AG) recurrences until day +365 in 76 patients who received pre-emptive ganciclovir (GCV) therapy prompted by AG 2 positive cells. Sixty-two episodes of AG recurrences were detected in 33 of the 52 patients who had positive AG. Survival analysis showed a 45.4% probability of AG recurrence on day +100, 64.8% on day +180 and 71.2% on day +365. The median time for AG recurrences was 113 (35 to 343) days. Thirty-five of the 62 episodes (56.4%) occurred after day +100. More than 70% of the patients responded to a 2-week course of GCV and no CMV disease was observed shortly after discontinuation of GCV. The Cox proportional model showed a significant effect of AG recurrences on patient’s follow-up only when the patient developed chronic GVHD (P = 0.012). Extended surveillance favored early introduction of GCV and late CMV pneumonia occurred in only one of the 76 patients (1.3%). AG recurrences are frequent after day +100 and extended surveillance until day +365 is recommended for patients who develop chronic GvHD.Bone Marrow Transplantation (2001) 28, 1053–1059.

The incidence, treatment and outcome of CMV interstitial pneumonia (CMV-IP) were reviewed in 139 consecutive allogeneic BMT patients undergoing extended CMV antigenemia surveillance and two different ganciclovir (GCV) strategies to control CMV infection. Nineteen cases of CMV-IP were reviewed, 16 of 63 patients (25.4%) who received early GCV treatment (ET) and three of 76 patients (3.9%) who received pre-emptive (PE) GCV therapy. In the ET group, the median time for occurrence of CMV-IP was 55 (range 36 to 311) days. Two patients had three episodes of CMV-IP recurrences after day +100. CMV-IP-related death occurred in two patients (15.4%). In the PE group, 41 patients received pre-emptive GCV therapy prompted by the appearance of positive antigenemia 2 cells. The median time for the occurrence of CMV-IP was 92 (range 48 to 197) days. Response to therapy was observed when GCV was introduced within 6 days of antigenemia positivity. The use of IVIg in association with GCV did not play a major role in response to therapy. The median time for occurrence of CMV-IP was delayed during PE strategy and the cost-effectiveness of CMV surveillance after day +100 should be investigated in this population.

Nocardiosis has rarely been described after BMT. When the doses of immunosuppressive therapy were tapered, a 46-year-old BMT recipient developed chronic graft-versus-host disease (GVHD) and immunosuppressive drugs were increased. Sixteen days later the patient developed nocardiosis diagnosed by lung biopsy. Trimethoprim/sulfamethoxazole (TMP/SMZ) was initiated but the doses were reduced because of rising creatinine levels. Skin and cerebral dissemination of nocardiosis was observed and TMP/SMZ doses were increased. After 4 months, the brain lesion was unaltered despite resolution of pulmonary lesions. Clinical improvement was observed after drainage of the brain abscess. [ABSTRACT FROM AUTHOR]
