Weeks Of Intravenous Ganciclovir Research Articles

Treatment of congenital cytomegalovirus infection.

Congenital cytomegalovirus (CMV) is the most common cause of congenital infection worldwide, the most common nongenetic cause of sensorineural hearing loss in children, and a cause of neurodevelopmental disorders in the brain. Infants with symptomatic congenital CMV infection may benefit from hearing and neurodevelopmental outcomes, particularly if antiviral treatment is initiated within the first month of life. Infants with life-threatening symptoms are recommended to receive 2-6 weeks of intravenous ganciclovir and then switch to oral valganciclovir, and those without life-threatening symptoms are recommended to use oral valganciclovir during the entire 6-month period. During antiviral drug treatment, absolute neutrophil count, platelet count, blood urea nitrogen, creatinine, and liver function tests were performed to identify neutropenia, thrombocytopenia, renal failure, and liver failure. This review investigated the evidence to date of treating congenital CMV infection.

Neurodevelopmental outcomes following ganciclovir therapy in symptomatic congenital cytomegalovirus infections involving the central nervous system

Background Ganciclovir protects against hearing deterioration in infants with symptomatic congenital cytomegalovirus (CMV) disease involving the central nervous system (CNS). Objectives To assess the neurodevelopmental impact of ganciclovir therapy in this population. Study design 100 neonates were enrolled into a controlled Phase III study of symptomatic congenital CMV involving the CNS, and were randomized to either 6 weeks of intravenous ganciclovir or no treatment. Denver developmental tests were performed at 6 weeks, 6 months, and 12 months. For each age, developmental milestones that ≥90% of normal children would be expected to have achieved were identified. The numbers of milestones not met (“delays”) were determined for each subject. The average number of delays per subject was compared for each treatment group. Results At 6 months, the average number of delays was 4.46 and 7.51, respectively, for ganciclovir recipients and “no treatment” subjects ( p = 0.02). At 12 months, the average number of delays was 10.06 and 17.14, respectively ( p = 0.007). In a multivariate regression model, the effect of ganciclovir therapy remained statistically significant at 12 months ( p = 0.007). Conclusions Infants with symptomatic congenital CMV involving the CNS receiving intravenous ganciclovir therapy have fewer developmental delays at 6 and 12 months compared with untreated infants. Based on these data as well as the previously published data regarding ganciclovir treatment and hearing outcomes, 6 weeks of intravenous ganciclovir therapy can be considered in the management of babies with symptomatic congenital CMV disease involving the CNS. If treatment is initiated, it should be started within the first month of life and patients should be monitored closely for toxicity, especially neutropenia. Since existing data only address the treatment of symptomatic congenital CMV disease involving the CNS, these data cannot be extrapolated to neonates with other manifestations of CMV disease, including asymptomatic babies and symptomatic babies who do not have CNS involvement.

502: CMVIG Decreases the Risk of Cytomegalovirus Infection but Not Disease after Pediatric Lung Transplantation

A retrospective review of pediatric lung transplant recipients at fourteen sites in North America and Europe was conducted to evaluate the impact of adding cytomegalovirus immunoglobulin (CMVIG) prophylaxis to at least three weeks of intravenous ganciclovir in pediatric lung transplant recipients. Data were recorded for the first year after transplantation. Associations between time to CMV and risk factors, including CMVIG use, were assessed by multivariable Cox proportional hazards models. Of 599 subjects whose charts were reviewed, 329 received at least three weeks of ganciclovir with 62 (19%) receiving CMVIG. CMVIG was administered more frequently with CMV donor-positive/recipient-negative (D+/R−) serostatus (p<0.05). In multivariable models, subjects who did not receive CMVIG as part of their prophylaxis were three times more likely to develop CMV infection (HR 3.4; 95% CI 1.2, 9.5) independent of CMV serostatus. However, CMVIG administration was not associated with decreased risk of episodes of CMV disease. Receipt of CMVIG was not associated with decreased risks of post-transplant morbidities (acute rejection, respiratory viral infection or early bronchiolitis obliterans) or morbidity within the first year after pediatric lung transplantation. The use of CMVIG in addition to antiviral prophylaxis in pediatric lung transplantation requires further evaluation in pediatric lung transplant recipients.

High Incidence of Cytomegalovirus Disease in D +/R − Heart Transplant Recipients Shortly After Completion of 3 Months of Valganciclovir Prophylaxis

Cytomegalovirus (CMV) infection remains a serious problem after heart transplantation. Recipients with D(+)/R(-) CMV serostatus often receive prophylaxis with valganciclovir, but the optimal duration of such therapy after heart transplant is unknown. We retrospectively reviewed the clinical course of all adult cardiac transplant recipients with D(+)/R(-) CMV serostatus at the UT Southwestern Medical Center between January 2003 and December 2006. Standard immunosuppression included basiliximab induction therapy and the CMV prophylaxis included CMV hyperimmune globulin, 2 weeks of intravenous ganciclovir and 3 months of oral valganciclovir. Seven patients met the study criteria. Six of the 7 patients (86%) developed CMV disease. Five of these 6 patients presented with CMV disease within 3 months of the cessation of valganciclovir prophylaxis. There was a high incidence of CMV disease in D(+)/R(-) heart transplant recipients despite CMV hyperimmune globulin, 2 weeks of intravenous ganciclovir and 3 months of valganciclovir prophylaxis. CMV infection occurred consistently within 2 to 3 months of cessation of valganciclovir. Alternative strategies for CMV prophylaxis, including an extension of valganciclovir prophylaxis to 6 months after heart transplantation, needs to be investigated.

Acute Rejection and Cardiac Allograft Vascular Disease Is Reduced by Suppression of Subclinical Cytomegalovirus Infection

Anticytomegalovirus (CMV) prophylaxis prevents the acute disease but its impact on subclinical infection and allograft outcome is unknown. We sought to determine whether CMV prophylaxis administered for three months after heart transplant would improve patient outcomes. This prospective cohort study of 66 heart transplant recipients compared aggressive CMV prophylaxis (n = 21, CMV hyperimmune globulin [CMVIG] plus four weeks of intravenous ganciclovir followed by two months of valganciclovir); with standard prophylaxis (n = 45, intravenous ganciclovir for four weeks). Prophylaxis was based on pretransplant donor (D) and recipient (R) CMV serology: R-/D+ received aggressive prophylaxis; R+ received standard prophylaxis. Outcome measures were: CMV infection assessed by DNA-polymerase chain reaction on peripheral blood polymorphonuclear leukocytes, acute rejection, and cardiac allograft vascular disease (CAV) assessed by intravascular ultrasound. All patients completed one year of follow-up. RESULTS.: CMV infection was subclinical in all but four patients (two in each group). Aggressively treated patients had a lower incidence of CMV infection (73 +/- 10% vs. 94 +/- 4%; P = 0.038), and an independent reduced relative risk for acute rejection graded > or =3A (relative risk [95% CI] = 0.55 [0.26-0.96]; P = 0.03), as compared with the standard prophylaxis group. Aggressively prophylaxed patients also showed a slower progression of CAV, in terms of coronary artery lumen loss (lumen volume change=-21 +/- 13% vs. -10+/-14%; P = 0.05); and vessel shrinkage (vessel volume change = -15 +/- 11% vs. -3 +/- 18%; P = 0.03). Prolonged (val)ganciclovir plus CMVIG reduces viral levels, acute rejection, and allograft vascular disease, suggesting a role for chronic subclinical infection in the pathophysiology of the most common diseases affecting heart transplant recipients.

Effect of ganciclovir therapy on hearing in symptomatic congenital cytomegalovirus disease involving the central nervous system: a randomized, controlled trial

Objective To evaluate the efficacy and safety of ganciclovir therapy in neonates with congenital cytomegalovirus (CMV) disease.Study design Neonates with symptomatic CMV disease involving the central nervous system were randomly assigned to receive 6 weeks of intravenous ganciclovir versus no treatment. The primary end point was improved brainstem-evoked response (BSER) between baseline and 6-month follow-up (or, for patients with normal baseline hearing, normal BSER at both time points).Results From 1991 to 1999, 100 patients were enrolled. Of these, 42 patients had both a baseline and 6-month follow-up BSER audiometric examination and thus were evaluable for the primary end point. Twenty-one (84%) of 25 ganciclovir recipients had improved hearing or maintained normal hearing between baseline and 6 months versus 10 (59%) of 17 control patients (P=.06). None (0%) of 25 ganciclovir recipients had worsening in hearing between baseline and 6 months versus 7 (41%) of 17 control patients (P<.01). A total of 43 patients had a BSER at both baseline and at 1 year or beyond. Five (21%) of 24 ganciclovir recipients had worsening of hearing between baseline and ≥1 year versus 13 (68%) of 19 control patients (P<.01). A total of 89 patients had absolute neutrophil counts determined during the course of the study; 29 (63%) of 46 ganciclovir-treated patients had grade 3 or 4 neutropenia during treatment versus 9 (21%) of 43 control patients (P<.01).Conclusions Ganciclovir therapy begun in the neonatal period in symptomatically infected infants with CMV infection involving the central nervous system prevents hearing deterioration at 6 months and may prevent hearing deterioration at ≥1 year. Almost two thirds of treated infants have significant neutropenia during therapy.

Treatment of Active Cytomegalovirus Disease with Oral Ganciclovir in Renal Allograft Recipients: Monitoring Efficacy with Quantitative Cytomegalovirus Polymerase Chain Reaction

Treatment regimens of patients with active cytomegalovirus (CMV) disease require 2-3 weeks of intravenous ganciclovir (GCV) with/without CMV hyperimmune globulin. Oral GCV is effective as a prophylactic agent in prevention of CMV disease. Here we explored the utility of oral GCV as a treatment of active CMV disease. Fifteen renal allograft recipients (CMV donor+/recipient- [53%], CMV donor+/recipient+ [40%] or CMV donor-/recipient+ [7%]) developed active CMV disease. Cytomegalovirus polymerase chain reaction (CMV-PCR) tests were performed at the time of presentation and patients were treated with oral ganciclovir 1 g tid (adjusted for renal function). Patients were monitored for efficacy of treatment by assessment of clinical symptoms and CMV-PCR. Treatment was continued until the CMV-PCR copy number was negative and symptoms resolved. The mean CMV-PCR copy number at the time of diagnosis was 580 copies/microg DNA (nl: < 5 copies/microg DNA). After 5-7 days of treatment, the mean copy number was 65 copies/microg DNA. Fourteen of 15 patients responded well to oral ganciclovir, with complete resolution of clinical symptoms and eradication of CMV-PCR positivity. One patient did not respond to oral ganciclovir therapy due to probable noncompliance. Our data suggest that oral ganciclovir treatment, coupled with careful CMV-PCR monitoring, may be a reasonable alternative to long-term intravenous ganciclovir.
