Oral ganciclovir for patients with cytomegalovirus retinitis treated with a ganciclovir implant. Roche Ganciclovir Study Group

BACKGROUND: The intraocular ganciclovir implant is effective for local treatment of cytomegalovirus retinitis in patients with the acquired immunodeficiency syndrome (AIDS), but it does not treat or prevent other systemic manifestations of cytomegalovirus infection. METHODS: Three hundred seventy-seven patients with AIDS and unilateral cytomegalovirus retinitis were randomly assigned to one of three treatments: a ganciclovir implant plus oral ganciclovir (4.5 g daily), a ganciclovir implant plus oral placebo, or intravenous ganciclovir alone. The primary outcome measure was the development of new cytomegalovirus disease, either contralateral retinitis or biopsy-proved extraocular disease. RESULTS: The incidence of new cytomegalovirus disease at six months was 44.3 percent in the group assigned to the ganciclovir implant plus placebo, as compared with 24.3 percent in the group assigned to the ganciclovir implant plus oral ganciclovir (P=0.002) and 19.6 percent in the group assigned to intravenous ganciclovir alone (P<0.001). As compared with placebo, oral ganciclovir reduced the overall risk of new cytomegalovirus disease by 37.6 percent over the one-year period of the study (P=0.02). However, in the subgroup of 103 patients who took protease inhibitors, the rates of new cytomegalovirus disease were low and of similar magnitude, regardless of treatment assignment. Progression of retinitis in the eye that initially received an implant was delayed by the addition of oral ganciclovir, as compared with placebo (P=0.03). Treatment with oral or intravenous ganciclovir reduced the risk of Kaposi's sarcoma by 75 percent (P=0.008) and 93 percent (P<0.001), respectively, as compared with placebo. CONCLUSIONS: In patients with AIDS and cytomegalovirus retinitis, oral ganciclovir in conjunction with a ganciclovir implant reduces the incidence of new cytomegalovirus disease and delays progression of the retinitis. Treatment with oral or intravenous ganciclovir also reduces the risk of Kaposi's sarcoma.     

Fatal reactivation of postnatal cytomegalovirus infection with rapid emergence of ganciclovir resistance in an infant after allogeneic stem cell transplantation

Human cytomegalovirus (HCMV) can cause serious problems after hematopoietic stem cell transplantation. The death of a pediatric transplant recipient after reactivation of a postnatal HCMV infection with bilateral retinitis and pneumonitis is described. Sequencing of the HCMV UL97 region revealed a compartment-specific mutation (H520Q) in urine conferring ganciclovir resistance.     

Combined ganciclovir and foscarnet in pediatric cytomegalovirus retinitis.

Cytomegalovirus retinitis is the leading cause of blindness in adults and children with acquired immunodeficiency syndrome (AIDS). Although clinical trials on therapy exist for adults, management of cytomegalovirus retinitis in children is not as well-documented. This report describes the clinical course of a 3-year-old child with cytomegalovirus retinitis. After initial failure with single-agent ganciclovir intravenous treatment, early institution of combined treatment with foscarnet and ganciclovir halted progression of the retinitis. This case report highlights the aggressive nature of cytomegalovirus retinitis in children and the consideration of early combined therapy compared to adult patients.     

Randomized prospective trial of ganciclovir maintenance therapy for cytomegalovirus retinitis

We report the first randomized prospective comparative study of long-term maintenance ganciclovir (9-[2-hydroxy-1-(hydroxymethyl)ethoxymethyl]guanine, BW759U, DHPG) therapy for cytomegalovirus retinitis in patients with the acquired immunodeficiency syndrome (AIDS). Eleven retinitis patients who received a 10-day course of ganciclovir induction therapy and then were randomized to receive either immediate daily ganciclovir maintenance therapy or deferred maintenance (eight deferred maintenance, three immediate maintenance) were evaluated for drug efficacy. Median time to retinitis progression was 42 days for the immediate maintenance group compared with 16 days for the deferred maintenance group, (P = 0.07). After crossing over to maintenance therapy, patients in the deferred group had a median time to retinitis progression of 58 days compared to 16 days while not on maintenance therapy (P = 0.13). Only 9% of cultures obtained while patients received maintenance therapy were positive for cytomegalovirus, vs 40% of those obtained off maintenance (P less than 0.001). We can state then that maintenance therapy with ganciclovir delays, but does not halt, progression of cytomegalovirus retinitis and suppresses, but does not eradicate, cytomegalovirus shedding in patients with AIDS.     

Combined and alternating ganciclovir and foscarnet in acute and maintenance therapy of human immunodeficiency virus-related cytomegalovirus encephalitis refractory to ganciclovir alone

Summary Cytomegalovirus (CMV) causes life-threatening disseminated infections and in particular vision-threatening infections of the retina in patients with the acquired immunodeficiency syndrome. Ganciclovir currently represents the most frequently used therapy for CMV retinitis. However, cases of ganciclovir-resistant CMV strains have been described, in which foscarnet seems to be an effective alternative. Both drugs have serious toxicities, and relapses frequently occur during maintenance therapy. In a patient with CMV encephalitis, we administered a 3-week combination ganciclovir/foscarnet induction therapy (ganciclovir 5 mg/kg every 12 h; foscarnet 60 mg/kg every 8 h), followed by an alternating maintenance administration of both drugs every other day (ganciclovir 5 mg/kg, foscarnet 120 mg/kg) to reduce toxicity and resistance. This regimen was tolerated well and seemed to be more effective than ganciclovir alone in a patient with CMV encephalitis.Abbreviations AIDS acquired immunodeficiency syndrome - CMV cytomegalovirus - CNS central nervous system - CSF cerebrospinal fluid - CT computed tomography - ED50 50% effective dose - ELISA enzyme-linked immunosorbent assay - HIV human immunodeficiency virus - MRI magnetic resonance imaging     

Early treatment with ganciclovir to prevent cytomegalovirus disease after allogeneic bone marrow transplantation.

BACKGROUND. Cytomegalovirus (CMV) infection is a major cause of morbidity and mortality after allogeneic bone marrow transplantation. We conducted a controlled trial of ganciclovir for the early treatment of CMV infection in asymptomatic recipients of bone marrow transplants whose surveillance cultures for CMV became positive. METHODS. Bone marrow--allograft recipients who were seropositive for CMV antibodies or who received seropositive marrow were screened for CMV excretion by culture of throat swabs, blood, urine, or bronchoalveolar-lavage fluid. In this double-blind trial, 72 patients who had marrow engraftment and were excreting virus were randomly assigned to receive either placebo or ganciclovir (5 mg per kilogram of body weight twice a day for one week, followed by 5 mg per kilogram per day) for the first 100 days after transplantation. Patients were followed for the development of biopsy-confirmed CMV disease, ganciclovir-related toxicity, and survival. RESULTS. Between assignment to the study drug and day 100 after transplantation, CMV disease developed in only 1 of the 37 patients assigned to receive ganciclovir (3 percent), but in 15 of the 35 patients assigned to receive placebo (43 percent, P less than 0.00001). The ganciclovir recipients had rapid suppression of virus excretion; 85 percent had negative cultures after one week of treatment, as compared with 44 percent of the placebo group (P = 0.001). The principal toxic reaction was neutropenia; 11 ganciclovir recipients had an absolute neutrophil count below 0.75 x 10(9) per liter, as compared with 3 placebo recipients (P = 0.052). Treatment was discontinued in 11 ganciclovir recipients and 1 placebo recipient because of neutropenia (P = 0.003). After treatment was stopped, the neutrophil count recovered in all patients. Overall survival was significantly greater in the ganciclovir group than in the placebo group both 100 days and 180 days after transplantation (P = 0.041 and 0.027, respectively). CONCLUSIONS. Early treatment with ganciclovir in patients with positive surveillance cultures reduces the incidence of CMV disease and improves survival after allogeneic bone marrow transplantation.     

Clinical safety and efficacy of first indigenous recombinant hepatitis B vaccine

A pilot study was conducted to assess the clinical safety and immunogenicity of an indigenously developed recombinant hepatitis B vaccine (Shanvac B) in 18 healthy adults. 20 microg of vaccine was administered at 0, 1 and 2 months. Protective anti HBs titres developed in 22%, 77% and 100% one month after 1st, 2nd and 3rd dose of vaccination, respectively. The geometric mean titre after the 3rd dose was 1015.29 mIu/ml. The vaccine was well tolerated with minor local and systemic side effects in 28% and 22%, respectively. The indigenously developed recombinant hepatitis B vaccine is safe, well tolerated and highly immunogenic.
