Abstract: | 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 preemptive (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 > or =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. |
