Patients were eligible for the study if they had had two or more MS relapses in the 2-year period before enrollment. Seventy patients with Expanded Disability Status Scale scores of 0 to 5.5 were randomly assigned to receive 1 gram of valacyclovir (n = 36) or placebo (n = 34) three times daily for 24 weeks. Patients underwent MRI every fourth week for 32 weeks: twice during pretreatment, six times during treatment, and once after treatment. Scoring of neurologic disability was performed at the start and end of the treatment period. The primary endpoint was the number of new active MRI-evident lesions over 24 weeks of treatment. Secondary endpoints included other MRI measures and clinical endpoints.
In a randomized study, we observed a higher incidence of biopsy-proven acute rejection with pre-emptive valganciclovir therapy as compared with valacyclovir prophylaxis for prevention of cytomegalovirus (CMV) disease after renal transplantation (RTx). Persistence of the virus within the allograft could stimulate the alloimmune response. The aim of our study was to evaluate intragraft CMV infection in patients randomized to the trial.

Treatment with oral valacyclovir as the sole antiviral therapy resulted in complete resolution of retinitis. Final BCVA and retinal detachment rate were comparable with previously reported outcomes for intravenous acyclovir.
Corticosteroids are widely used in the treatment of idiopathic facial paralysis (Bell's palsy), but the effectiveness of additional treatment with an antiviral agent is uncertain. Significant morbidity can be associated with severe cases of Bell's palsy.

76,269 patients received acyclovir or valacyclovir and 84,646 received famciclovir. On average, patients were aged 76 [IQR, 71-81] years and prescription duration was 7 days. Acyclovir or valacyclovir use was not associated with a higher risk of hospital admission with AKI (209 [0.27%] events with acyclovir or valacyclovir vs 238 [0.28%] events with famciclovir [relative risk, 0.97; 95% CI, 0.81-1.17]). Results were consistent in adjusted analyses, in all subgroups, and in the subpopulation with laboratory measurements.

Double-blind and open study using valacyclovir over two wrestling seasons from 1996 through 1998.
Antiviral prophylaxis is commonly used in recipients of solid-organ transplants with the aim of preventing the clinical syndrome associated with cytomegalovirus infection. We undertook a systematic review to investigate whether this approach affects risks of cytomegalovirus disease and death.

Herpes virus infections must be investigated in children with posterior or panuveitis. PCR analysis is a reliable technique for diagnosis. This case emphasizes that clinical presentation can be atypical and that a negative viral serology does not exclude an acute or a past herpetic infection.

Herpes simplex virus type 2 (HSV-2) infections are frequent in HIV (human immunodeficiency virus) infected patients. In those cases, genital herpes may have an atypical clinical presentation. Hypertrophic and vegetating variants are unusual. The authors describe a case of hypertrophic perianal herpes in an HIV patient with unsatisfactory response to acyclovir and valacyclovir, successfully treated with imiquimod. Hypertrophic genital herpes cases are frequently refractory to antiviral treatments. In our experience, imiquimod is an efficient, safe and well tolerated treatment that should be considered in therapeutic approach of these patients.

Population-based historical cohort study of 837,795 live-born infants in Denmark from January 1, 1996, to September 30, 2008. Participants had no diagnoses of chromosomal aberrations, genetic syndromes, birth defect syndromes with known causes, or congenital viral infections. Nationwide registries were used to ascertain individual-level information on dispensed antiviral drugs, birth defect diagnoses (categorized according to a standardized classification scheme), and potential confounders.
Congenital cytomegalovirus (CMV) is the most common viral infection, affecting nearly 40,000 infants each year in the United States. Of seronegative women, 1-4% will acquire a primary infection during pregnancy, and the majority of these women will be asymptomatic. Prior maternal exposure to CMV does not preclude neonatal infection. The purpose of this document is to review diagnosis of primary maternal CMV infection, diagnosis of fetal CMV infection, and whether antenatal therapy is warranted. We recommend the following: (1) that women with a diagnosis of primary CMV infection in pregnancy be advised that the risk of congenital infection is 30-50%, on average, and that the severity of infection varies widely (Best Practice); (2) for women suspected of having primary CMV infection in pregnancy, we recommend that diagnosis should be either by IgG seroconversion or with positive CMV IgM, positive IgG, and low IgG avidity (grade 1B); (3) amniocentesis is the best option as a prenatal diagnostic tool to detect fetal congenital CMV infection, performed >21 weeks of gestation and >6 weeks from maternal infection (grade 1C); (4) we do not recommend routine screening of all pregnant women for evidence of primary CMV infection at this time (grade 1B); and (5) we do not recommend antenatal treatment with ganciclovir or valacyclovir; and we recommend that any antenatal therapy, either with antivirals or CMV hyperimmune globulin, should only be offered as part of a research protocol (Best Practice).

The clinical evolution suggested that the syndrome was related to the antiviral therapy. ARF preceded neurotoxicity. We suggest that high bioavailability, reduced glomerular filtration rate (GFR) related to age, and possibly the simultaneous ingestion of other drugs could have caused these side effects. We recommend the emphasis on potential side effects of antiviral therapy when treating geriatric patients even if Scr is in the normal range.
