Cytogam® added to antiviral medication significantly reduces serious CMV disease in heart transplant patients1,2
High-risk heart transplant patients (n=27) received Cytogam® therapy for four months after transplant, along with ganciclovir for 28 days. Results were compared to matched historical controls (n=27) who received ganciclovir alone. Compared to treatment with ganciclovir alone, combination therapy including Cytogam® had the following notable results1:
- Significantly higher disease free rates over 3 years
- Significantly greater 3-year survival
- Significantly higher rejection-free rates 3 years post-transplant (P< 0.05)
- Reduced transplant coronary-artery disease
- Reduced coronary intimal thickening (overall and > 0.3 mm; P = 0.01)

In a separate study, 21 D+R- patients were treated with CMVIG from 72 hours after transplant and periodically over 16 weeks, plus 4 weeks of ganciclovir followed by 2 or more months of valganciclovir. Results were compared to results of 45 R+ patients who received only ganciclovir for 4 weeks. The patients receiving combination therapy had the following results, compared to those receiving ganciclovir alone2:
- 28% reduction in relative risk for CMV infection
- Significantly less lumen-volume change (P =0.06) and less vessel shrinkage (P =0.04)
- Less graft vascular disease
