A 49-year-old liver transplant patient with 4-year history of epilepsy after initiation of cyclosporine developed increasingly frequent seizures over 3 months. Serial brain magnetic resonance imaging showed left temporoparietal cortical edema that gradually improved despite clinical decline. Herpes simplex virus type-1 (HSV-1) DNA was detected in cerebrospinal fluid by polymerase chain reaction. Cerebrospinal fluid HSV-1&2 IgM was negative. Seizures were controlled after acyclovir treatment, and the patient remained seizure free at 1-year follow-up.

Rat pheochromocytoma (PC12) cells differentiated with nerve growth factor (Nd-PC12) were used to investigate the establishment of a non-productive herpes simplex virus type 1 (HSV-1) infection that is reversible. The results of this work are as follows: (i) Nd-PC12 cultures could be maintained as long term (>7 weeks) non-dividing cultures only when plated on collagen-coated dishes in the absence of serum; (ii) Infection of Nd-PC12 with HSV-1 strains KOS and 17 in the transient presence of acycloguanosine (ACV) resulted in all cultures free of detectable levels of infectious virus at the time of ACV removal and ACV was not needed to maintain the non-productive quiescent state in the subsequent 8 weeks; (iii) These persistently infected and quiescent (QIF)-PC12 cultures demonstrated both spontaneous and forskolin-inducible virus production, at low (5%) and high frequencies (92-100%), respectively during the first 2 weeks post-ACV withdrawal. (iv) In contrast to other in vitro models, HSV-1 failed to reactivate following removal of nerve growth factor. (v) A high percentage of QIF-PC12 cultures (50-100%) produced virus in response to forskolin treatment as long as 7 weeks post-ACV withdrawal. (vi) Expression of HSV-1 productive genes (i.e. alpha0, alpha4, alpha27, UL30 and UL18) dropped precipitously in the presence of ACV and remained undetectable or continued to decline following its removal, whereas the levels of LAT and the host gene G3PDH remained relatively constant throughout the 31 day study period as measured by RT-PCR. These results indicate that QIF-PC12 cells offer a novel, neuronal cell culture system that may enhance our ability to study HSV-1 reactivation from a cryptic, latent-like, non-productive state in the absence of replication inhibitors.

Prophylaxis-based antiviral treatment and intensive monitoring followed by pre-emptive antiviral treatment are both commonly used management strategies to reduce risk of cytomegalovirus (CMV) infection following renal transplantation. This study employed a decision-model approach using published efficacy data and information from a recent survey of French clinical practice to consider the relative costs and outcomes associated with CMV prevention strategies for high-risk patient groups. The cost per case of treating tissue invasive and symptomatic CMV disease was estimated at euro 15,431 and euro 10,852, respectively. In the highest infection-risk patient group (positive donor with no previous CMV history) prophylactic oral valaciclovir was shown to avoid the greatest number of CMV disease cases (35 cases per 100 transplanted patients) and reduced the overall CMV-related costs per transplanted patient by around 14% over a'wait-and-treat' baseline strategy. In contrast, intensive monitoring and preemptive treatment resulted in a much higher cost per transplanted patient. This analysis suggests that prophylactic treatment remains the most cost-effective approach to the management of CMV in renal-transplanted patients. Further comparative studies between prophylactic and pre-emptive treatment would be a valuable addition to the current evidence based on CMV prevention.

Bio-based nanocomposites were prepared using starch nanocrystals obtained by acid hydrolysis of native starches using different acid sources. In recent times, focuses on starch nanocrystals (SNCs) have been increasing in number of research works dedicated to the development of bio-nanocomposites by blending with different biopolymeric matrices. The work mainly deals with the preparation of starch nanocrystals using different native starches by acid hydrolysis using hydrochloric acid and trifluroacetic acid. The as-prepared starch nanocrystals are having high crystallinity and more platelet morphologies, and used as a drug carrying filler material in the hydrogel formulations with the care of different polymer matrices. The condensed work also concentrates on the dispersion of antiviral drug in the hydrogels, which are applied onto biocompatible bio-membrane to be formulating a complete transdermal patch. The acid hydrolysed starch nanocrystals were thoroughly characterized using TEM, SEM, particle size analysis and zeta potential. Their thermal stability and the crystalline properties were also characterized using TG-DSC and XRD respectively. The physiochemical interaction and compatibility between the drug and the SNCs filler in the polymeric hydrogels were evaluated using FT-IR analysis. The formulated hydrogels were subjected to evaluation of in vitro permeation studies using Franz diffusion studies. The in vitro study was indicated substantial guarantee for the fabrication of drug dispersed in polymeric hydrogels using SNCs as filler matrices for a successful transdermal drug delivery.

We have previously reported that a retrovirus vector (LNAF0.3TK) carrying a herpes simplex virus thymidine kinase gene regulated only by the 0.3-kb human alpha-fetoprotein (AFP) promoter provides ganciclovir (GCV)-mediated cytotoxicity in high AFP-producing human hepatoma cells but not in low AFP-producing cells. In the present study, a retrovirus vector (LNAF0.3(E+)TK), in which herpes simplex virus thymidine kinase gene expression is under the control of a human AFP enhancer directly linked to its promoter, was constructed and compared with LNAF0.3(E+)TK. In the intermediate and low AFP-producing human hepatoma cells PLC/PRF/5 and huH1/cl.2, respectively, as well as in the high AFP-producing human hepatoma cells (HepG2), LNAF0.3(E+)TK sensitized these cells to GCV in vitro but did not affect cell growth in nonhepatoma cells (HeLa). In an animal model using athymic mice harboring PLC/PRF/5 cells, GCV treatment resulted in more pronounced growth inhibition in the LNAF0.3(E+)TK virus-infected cells than in the LNAF0.3(E+)TK virus-infected cells. These results indicate that the human AFP enhancer that is directly linked to its promoter involves selective and enhanced tumoricidal activity in gene therapy for hepatocellular carcinoma.

We report an AIDS patient with cytomegalovirus (CMV) retinitis that developed from an early minor lesion and progressed to extended involvement of the retina and severe deterioration of vision due to poor compliance with ganciclovir treatment. A 33-year-old man was known to have acquired immunodeficiency syndrome (AIDS) for eight months. The patient had no complaint of visual symptoms. A routine eye examination revealed his visual acuity to be 6/6 in both eyes. The dilated eye fundus examination using indirect ophthalmoscopy disclosed a localized white yellowish granular lesion in the peripheral retina of the right eye and a completely normal left eye. CMV retinitis with initial manifestation in the right eye was diagnosed. Due to incomplete treatment with ganciclovir, the retinal lesion rapidly enlarged and extended to the posterior pole, with eventual destruction of the nerve fiber layer and optic disc. The visual acuity of right eye dropped from 6/6 to 1/60 within six months. This case report indicates the importance of early, dilated eye fundus examination and recognition of early CMV retinitis in order to salvage visual function in AIDS patients. Completion of the anti-CMV treatment course in halting the progression of CMV retinitis is also emphasized.

Lymphoproliferative syndromes are the most common tumors in transplant recipients. More than 90% of posttransplantation lymphoproliferative syndromes (PTLS) are considered to be associated with Epstein-Barr virus, and 86% are of the B-cell line. Histopathology ranges from polymorphic-reactive to monomorphic forms. Clonality should be studied using molecular biology techniques. Clinically, a differentiation is usually made between early PTLS (occurring within 1 year after transplantation) and late PTLS, which occur as localized or disseminated nodal lymphomas. In localized forms, immunosuppression should be discontinued or decreased, and the involved area should be subsequently resected or irradiated. In disseminated cases, immunosuppression should be decreased and administration of acyclovir/ganciclovir should be considered. If this is not effective, treatment should be started with anti-CD20 monoclonal antibodies (rituximab). If no response occurs, use of chemotherapy, possibly with interferon, should be considered. Our aim was to report the incidence, clinical signs, and treatment in a series of patients undergoing lung transplantation (LTx).

Herpes zoster leukoencephalitis is a rare complication of varicella-zoster virus infection. Associated with high mortality, the majority of cases have been discovered postmortem; today, however, magnetic resonance imaging is being used successfully as an aid in the diagnosis of this disease. The first two reported cases of HIV-infected patients with herpes zoster leukoencephalitis who recovered clinically and showed complete resolution of the magnetic resonance demyelination images after acyclovir treatment are described. In addition, the cases of herpes zoster leukoencephalitis reported in the literature to date are reviewed.

Infections due to herpes simplex virus (HSV) resistant to acyclovir (ACV) represent an important clinical concern in immunocompromised patients. In order to switch promptly to an appropriate treatment, rapid viral susceptibility assays are required. We developed herein a genotyping analysis focusing on thymidine kinase gene (TK) mutations in order to detect acyclovir-resistant HSV in clinical specimens. A total of 85 HSV-1 positive specimens collected from 69 patients were analyzed. TK gene could be sequenced directly for 81 clinical specimens (95%) and 68 HSV-1 specimens could be characterized as sensitive or resistant by genotyping (84%). Genetic characterization of 67 susceptible HSV-1 specimens revealed 10 polymorphisms never previously described. Genetic characterization of 14 resistant HSV-1 revealed 12 HSV-1 with either TK gene additions/deletions (8 strains) or substitutions (4 strains) and 2 HSV-1 with no mutation in the TK gene. DNA polymerase gene was afterwards explored. With this rapid PCR-based assay, ACV-resistant HSV could be detected directly in clinical specimens within 24 h.

We report three patients with ophthalmic herpes zoster (HZ) manifestations on the background diagnosis of multiple myeloma (MM). It seems that immunocompromised status has caused reactivation of the varicella zoster virus (VZV) producing a well-characterised neurological syndrome and subsequent postherpetic neuralgia in two patients. One patient experienced lymphocytic leptomeningitis resulting in unilateral optic neuritis. All patients received similar myeloma disease-specific treatment prior to HZ reactivation. All patients were treated with thalidomide and steroids, and they thereafter underwent autologous stem cell transplantation. Prior to HZ reactivation they received new immunomodulatory drugs in the form of thalidomide in addition to bortezomib (2 patients) and lenalidomide (1 patient). Immediate specific antiviral therapy was successfully applied with intravenous acyclovir for 10 days, followed by long-term oral famciclovir maintenance. Two patients progressed to have chronic HZ ophthalmicus and postherpetic neuralgia requiring ongoing antiviral therapy and neuroepileptic medications for the neuropathic pain.

Two studies were performed to assess the relative bioavailability of Lovrak (Julphar, UAE) compared with Zovirax (Glaxo Wellcome, UK) at the International Pharmaceutical Research Center (IPRC), Amman, Jordan. One study involved acyclovir tablets and the other acyclovir suspension. Each study enrolled 24 volunteers and in both studies, after an overnight fasting, the two brands of acyclovir were administered as a single dose on 2 treatment days separated by 1 week washout period. After dosing, serial blood samples were collected for a period of 16 h. Plasma harvested from blood, was analysed for acyclovir by an HPLC method with UV detection. Various pharmacokinetic parameters including AUC0-t, AUC0-infinity, Cmax, Tmax, T1/2 and Kelm were determined from plasma concentrations for both formulations and found to be in good agreement with the reported values. AUC0-t, AUC(0-proportional to), and Cmax were tested for bioequivalence after log-transformation of data. No significant difference was found based on ANOVA; 90% confidence intervals for the test/reference ratio of these parameters were found within the bioequivalence acceptance range 80%-125%. Based on these statistical inferences it was concluded that a Lovrak tablet is bioequivalent to a Zovirax tablet and that Lovrak suspension is bioequivalent to Zovirax suspension.

Feline herpesvirus 1 (FHV-1) is a common cause of respiratory and ocular disease in cats. Especially in young kittens that have not yet reached the age of vaccination, but already lost maternal immunity, severe disease may occur. Therefore, there is a need for an effective antiviral treatment. In the present study, the efficacy of six antiviral drugs, i.e. acyclovir, ganciclovir, cidofovir, foscarnet, adefovir and 9-(2-phosphonylmethoxyethyl)-2, 6-diaminopurine (PMEDAP), against FHV-1 was compared in Crandell-Rees feline kidney (CRFK) cells using reduction in plaque number and plaque size as parameters.

Multidrug and toxin extrusion (MATE; SLC47A) proteins are membrane transporters mediating the excretion of organic cations and zwitterions into bile and urine and thereby contributing to the hepatic and renal elimination of many xenobiotics. Transported substrates include creatinine as endogenous substrate, the vitamin thiamine and a number of drug agents with in part chemically different structures such as the antidiabetic metformin, the antiviral agents acyclovir and ganciclovir as well as the antibiotics cephalexin and cephradine. This review summarizes current knowledge on the structural and molecular features of human MATE transporters including data on expression and localization in different tissues, important aspects on regulation and their functional role in drug transport. The role of genetic variation of MATE proteins for drug pharmacokinetics and drug response will be discussed with consequences for personalized medicine.

A case of limbic encephalitis in a patient who had undergone prolonged immunosuppressive treatment with i.v. cyclophosphamide and oral prednisolone for a microscopic polyangeitis is reported. A brain MRI scan revealed symmetric mesial temporal lobe lesions. Studies of cerebrospinal fluid (CSF) revealed a positive PCR for varicella-zoster virus (VZV) DNA in 2 separate samples. Owing to a delay in diagnosis, intravenous acyclovir was initiated only after 11 d of symptoms. PCR of CSF for VZV DNA became negative on day 14 of treatment while brain lesions had resolved on subsequent MRI scans. Limbic encephalitis is a novel form of VZV infection. When brain imaging is suggestive of limbic encephalitis in buy zovirax an immunocompromised patient, PCR of CSF for VZV DNA should be performed, as early antiviral treatment may improve the outcome.

ASP2151 was developed as a novel inhibitor of herpes simplex virus (HSV) and varicella-zoster virus helicase-primase. The anti-HSV activity of ASP2151 toward a clinical HSV isolate with acyclovir (ACV)-resistant/thymidine kinase (TK)-deficiency was characterized in vitro and in vivo using a plaque reduction assay and the ear pinna infection in mice. The IC(50) ranged from 0.018 to 0.024 μg/ml, indicating the susceptibility of TK-deficient HSV-2 was similar to that of wild-type HSV-2 strains. Anti-HSV activity of ASP2151 in vivo was evaluated in mice infected with wild-type HSV-2 and TK-deficient HSV-2 buy zovirax . ASP2151 significantly reduced the copy numbers of wild-type HSV-2 and TK-deficient HSV-2 at the inoculation ear pinna, while valacyclovir significantly reduced the copy number of wild type HSV-2 but not that of TK-deficient HSV-2 in the inoculated ear pinna. Thus, ASP 2151 showed therapeutic efficacy in mice infected with both wild-type and TK-deficient HSV-2. In conclusion, ASP2151 is a promising novel herpes helicase-primase inhibitor that indicates the feasibility of ASP2151 for clinical application for the treatment of HSV infections, including ACV-resistant/TK-deficient HSV infection.

The objective of this study was to evaluate the effect of 2 independent formulation variables on the drug release from a novel doughnut-shaped minitablet (DSMT) in order to optimize formulations for intraocular drug delivery. Formulations were based on a 3(2) full-factorial design. The 2 independent variables were the concentration of Resomer (% wt/wt) and the type of Resomer grade (RG502, RG503, and RG504), respectively. The evaluated response was the drug release rate constant computed from a referenced marketed product and in vitro drug release data obtained at pH 7.4 in simulated vitreous humor. DSMT devices were prepared containing either of 2 model drugs, ganciclovir or foscarnet, using a Manesty F3 tableting press fitted with a novel central-rod, punch, and die buy zovirax setup. Dissolution data revealed biphasic drug release behavior with 55% to 60% drug released over 120 days. The inherent viscosity of the various Resomer grades and the concentration were significant to achieve optimum release rate constants. Using the resultant statistical relationships with the release rate constant as a response, the optimum formulation predicted for devices formulated with foscarnet was 70% wt/wt of Resomer RG504, while 92% wt/wt of Resomer RG503 was ideal for devices formulated with ganciclovir. The results of this study revealed that the full-factorial design was a suitable tool to predict an optimized formulation for prolonged intraocular drug delivery.

We incubated PMA treated THP-1 cells with DHPG for one to five days at 37 degrees C before or after the infection. The cells were cultivated for 5 days at 37 degrees C then supernatants of culture were collected and they were added to fibroblast cultures. The infection of the fibroblasts was studied on the basis of immune detection of viral immediate early antigens (IEA) in nucleus 24h after culture. Incubation of infected THP-1 cells with 11.1 microM DHPG for 5 days at 37 degrees C resulted in 95 +/- 2% inhibition of the replication whereas incubation of the infected cells with the same concentration of DHPG for two days resulted buy zovirax in 50 +/- 5% inhibition. Pretreatment of cells with DHPG for 5 days induced a 50 +/- 4% decrease of the level of infectious particles produced by HCMV infected cells. This is the first report of the antiviral effect of DHPG in macrophagic-like cells.

HaNDL (transient headache and neurological deficits with cerebrospinal fluid lymphocytosis) syndrome is an infrequent condition included at group 7 "headache attributed to non-vascular intracranial disorder" in the recent International buy zovirax Classification of Headache Disorders (ICHD-3), code 7.3.5. The description states "migraine-like headache episodes (typically 1-12) accompanied by neurological deficits including hemiparaesthesia, hemiparesis and/or dysphasia, but positive visual symptoms only uncommonly, lasting several hours. There is lymphocytic pleocytosis. The disorder resolves spontaneously within 3 months". In this description confusional state is not considered as a main symptom, even if in the literature this aspect is frequently reported. Here, we report the cases of two young boys presenting with confusional state as the main complaint. The possible pathogenesis of the different clinical presentation is discussed.

Herpes simplex encephalitis (HSE) is a life-threatening consequence of herpes simplex virus (HSV) infection of the central nervous system (CNS). Although HSE is rare, mortality rates reach 70% in the absence of therapy and only a minority of individuals return to normal function. Antiviral therapy is most effective when started early, necessitating prompt diagnosis. The International Herpes Management Forum (IHMF) has issued guidelines to aid the diagnosis and treatment of HSE. Polymerase chain reaction (PCR) of the cerebrospinal fluid (CSF) is the diagnostic method of choice for HSE, but negative results need Zoloft 150 Mg to be interpreted in the context of the patient's clinical presentation and the timing of the CSF sampling. CSF virus culture is of little value in all but patients under the age of 6 months. CSF (intrathecal) antibody measurements are not recommended for acute diagnostic purposes. However, demonstration of an intrathecal HSV antibody response may be helpful in retrospective diagnosis or in cases in which CSF is sampled only late after onset of infection and PCR is negative. Serum HSV antibody measurements are not of utility in the diagnosis of HSV encephalitis in adults. In children and young adults, HSV serology may help define whether HSE is part of a primary or a reactivated HSV infection, although the clinical features, therapy, and prognosis of these two forms of HSV encephalitis are similar. The IHMF recommends that all patients with HSE receive intravenous aciclovir 10 mg/kg every 8 h for 14-21 days. Owing to the life-threatening nature of the disease, if there is a delay in diagnostic test results therapy should not be withheld until they become available. After completion of therapy, PCR of the CSF can confirm the elimination of replicating virus, aiding further management of the patient. Clinical trials of other antiviral agents (i.e. adjunctive oral valaciclovir after intravenous aciclovir) for the treatment of HSE are underway. Herpes infection of the CNS, especially with HSV-2, can also cause both monophasic and recurrent aseptic meningitis, as well as myelitis or radiculitis. Limited evidence suggests that aciclovir may be effective in its treatment. Recurrent aseptic meningitis is predominantly caused by HSV-2 infection, and is characterized by self-limited episodes of fever, meningismus and severe headache. Many cases are indistinguishable from cases previously classified as "Mollaret's meningitis", a term that should now be reserved for idiopathic cases of recurrent aseptic meningitis.

Although cytomegalovirus infection is the most common infection transmitted via the placenta, there are no guidelines for routine screening to detect children congenitally infected with cytomegalovirus. From 1993 to 1997, maternal serum and cord vein blood of newborns was screened for HCMV-IgM (n = 21,183). Urine was examined for HCMV-excretion during the first postnatal week to prove HCMV infection in children who expressed HCMV-IgM in cord vein blood (n = 13) or who were born to mothers positive for HCMV-IgM in the serum (n = 234), or when both cord vein blood and maternal serum were positive for HCMV-IgM (n = 6). Congenital HCMV infection was detected in 17 newborns. To determine the incidence of congenital HCMV infection, only those mother/child pairs were selected in whom serum and cord vein blood were investigated (n = 5967 mother/child pairs). In this group 13 newborns were infected. The observed incidence for congenital HCMV infection is 0.21%. It is concluded that that this screening programme will detect those children at risk for congenital HCMV infection. These children Sinequan Mg have to be examined for virus excretion in the urine. Although the observed incidence is only 0.21%, congenital HCMV infection is a problem that can no longer be neglected because of its long-term sequelae.

The objective of this work was to increase the nasal absorption of acyclovir by using absorption enhancers. Acyclovir was selected as a model drug. A rat in situ nasal perfusion technique was utilized in the investigation to examine the rate and extent of absorption of acyclovir. In vitro enzymatic drug degradation study was carried out with rat nasal washings. Various experimental conditions such as nasal perfusion rate, pH of the perfusion medium and concentrations of absorption enhancers such as sodium deoxycholate, hydroxypropyl beta-cyclodextrin, sodium caprate, sodium tauroglycocholate and EDTA were optimized. Nasal absorption of acyclovir was pH dependent. Initial absorption rate constants were determined by the plot of log% remaining amount of drug in perfusate vs time. It was found maximum at pH 7.4 and decreased at lower and higher pH conditions. In in vitro enzymatic degradation study, no measurable degradation was observed during first week. The extent of drug absorption was increased via absorption enhancers. In vivo studies were carried out for the optimized formulation in rabbits and the pharmacokinetics parameters of nasal solution were compared with oral solution. Hydroxypropyl beta-cyclodextrin appeared to be more effective for enhancing the nasal absorption of acyclovir than the other absorption enhancers. The order of increasing absorption of acyclovir caused by the enhancers was hydroxypropyl beta-cyclodextrin>sodium deoxycholate>sodium caprate>sodium tauroglycocholate>EDTA.
