UNLABELLED: The usefulness of anti-CMV hyperimmune gammaglobulin (IgG-CMV, Cytotec) in lung transplant patients (LTx) is controversial. The objective of this study was to analyze the effectiveness of IgG-CMV in our LTx receptors.
PATIENTS AND METHODS: A retrospective study of LTx recipients treated with IgG-CMV as prophylaxis or as treatment for invasive disease. We used IgG-CMV associated with IV ganciclovir (GCV) as treatment for invasive disease. High-risk patients (CMV-negative recipients from CMV-positive donors; CMV-/+) were also with IgG-CMV prophylaxis during the first year. Other prophylactic uses of IgG-CMV were as an alternative to GCV in patients with related GCV toxicity, and as preemptive therapy in cases of persistent positive viral load (antigenemia > or = 1 cell and/or a PCR > or = 400) although oral GCV administration.
RESULTS: Between January 2000 and August 2003, 14 of the 74 lung transplant recipients (19%) received IgG-CMV as treatment for invasive disease (4 cases: 2 gastritis, 1 esophagitis, 1 hepatitis) and/or as prophylaxis (14 cases). All patients treated for invasive disease evolved favorably. No therapeutic failure were observed in CMV-/+ patients during treatment. Three of the six patients treated with IgG-CMV developed positive antigenemia despite treatment. The four patients treated for persistent antigenemia while receiving oral GCV achieved neutralization during the first month of treatment.
CONCLUSION: IgG-CMV associated with Gancyclovir is effective as treatment for invasive disease and as pre-emptive therapy in patients with persistent positive viral load. In CMV-/+ recipients, IgG-CMV prevents pneumonitis and delays the development of invasive disease after the first year.
