Epstein-Barr virus infectious mononucleosis can cause transient immune deficiency which may predispose to reactivation of latent herpes simplex virus (HSV) infection in the immunocompetent host. We report the case of a 15-year-old male who presented with severe odynophagia and herpes labialis during the course of Epstein-Barr virus infectious mononucleosis that had been diagnosed ten days before. Esophagoscopy revealed extensive ulcerations with distinct borders and whitish exudates at the mid and distal esophagus. Polymerase chain reaction detected HSV-1 DNA in the biopsy specimens. The patient was treated with intravenous acyclovir. The symptoms resolved rapidly within 3 days, in accordance with improved endoscopic findings.

Female workers at recreational facilities in northwestern Tanzania who were 16 to 35 years of age were interviewed and underwent serologic testing for HIV and HSV-2. We enrolled female workers who were HIV-seronegative and HSV-2-seropositive in a randomized, double-blind, placebo-controlled trial of suppressive treatment with acyclovir (400 mg twice daily). Participants attended mobile clinics every 3 months for a follow-up period of 12 to 30 months, depending on enrollment date. The primary outcome was the incidence of infection with HIV. We used a modified intention-to-treat analysis; data for participants who became pregnant were censored. Adherence to treatment was estimated by a tablet count at each visit.

In 1983, varicella zoster virus (VZV) disease was first recognized in the context of infection with the human immunodeficiency virus (HIV). Since that time, there have been many reports discussing the occurrence and clinical manifestations of hepes zoster in HIV-infected patients. We describe the development of prolonged herpes zoster in a patient with acquired immunodeficiency syndrome (AIDS) over the course of 104 days. Viral isolates at the three different clinical stages of the skin lesions were sensitive in vitro to acyclovir, and supposed to be a same strain by polymerase chain reaction (PCR) analysis. We also discuss an effective treatment for prolonged cases of zoster.

Viral infections, especially cytomegalovirus (CMV), are a leading cause of early death and morbidity after heart transplantation. Several strategies have been used to minimize the risk, including universal prophylaxis with ganciclovir or valganciclovir and preemptive therapy. Lately, everolimus (EVE) efficacy studies have shown a protective effect against CMV infection.

The neuroepithelial body (NEB) is a highly dynamic structure that responds to chronic airway injury through hyperplasia of associated pulmonary neuroendocrine (PNE) cells. Although NEB dysplasia is correlated with preneoplastic conditions and PNE cells are thought to serve as a precursor for development of small cell lung carcinoma, mechanisms regulating expansion of the PNE cell population are not well understood. Based on studies performed in animal models, it has been suggested that NEB-associated progenitor cells that are phenotypically distinct from PNE cells contribute to PNE cell hyperplasia. We have previously used a Clara cell-specific toxicant, naphthalene, to induce airway injury in mice and have demonstrated that naphthalene-resistant Clara cells, characterized by their expression of Clara cell secretory protein (CCSP), and PNE cells contribute to airway repair and associated hyperplasia of NEBs. This study was conducted to define the contribution of NEB-associated CCSP-expressing progenitor cells to PNE cell hyperplasia after Clara cell ablation. Transgenic (CCtk) mice were generated in which herpes simplex virus thymidine kinase was expressed within all CCSP-expressing cells of the conducting airway epithelium through the use of transcriptional regulatory elements from the mouse CCSP promoter. Chronic administration of ganciclovir (GCV) to CCtk transgenic mice resulted in selective ablation of CCSP-expressing cells within conducting airways. Proliferation and hyperplasia of PNE cells occurred in the absence of detectable proliferation among any other residual airway epithelial cell populations. These results demonstrate that PNE cells function as a self-renewing progenitor population and that NEB-associated Clara cells are not necessary for PNE cell hyperplasia.

When compared with historical data on the ocular complications of smallpox vaccination, the incidence of ocular complications during the DoD Smallpox Vaccination program has been low. In addition, the severity of disease seems to be less than during other vaccination periods. These findings perhaps are the result of improved screening of vaccinees, prevaccination counseling, postvaccination wound care, and the suggested efficacy of trifluridine in the treatment of ocular vaccinia.

Twenty-seven CMV seropositive adults due to receive a heart transplant were included in a single-center, randomized, double-blind study. Patients were randomized to receive either oral valacyclovir 2000 mg or oral acyclovir 200 mg four times daily starting within 3 days of heart transplant and continuing for 90 days. The primary outcome measure was time to development of CMV antigenemia assessed for 6 months after surgery. Other measures were time to asymptomatic CMV infection, symptomatic CMV infections, and end-organ CMV disease. Patients were monitored for other herpes infections, other opportunistic infections, and acute graft rejection. Safety was assessed by evaluating changes in hematology and clinical chemistry parameters and by the occurrence of adverse events.

We discovered 232 cases of extravasation involving 37 agents (in order of frequency): phenytoin, parenteral nutrition, calcium gluconate, potassium chloride, calcium chloride, dopamine, dextrose solutions, epinephrine, sodium bicarbonate, nafcillin, propofol, norepinephrine, mannitol, arginine, promethazine, vancomycin, tetracycline, dobutamine, vasopressin, sodium thiopental, acyclovir, amphotericin, ampicillin, cloxacillin, gentamicin, metronidazole, oxacillin, penicillin, amiodarone, albumin, furosemide, lipids, lorazepam, immunoglobulin, morphine, and sodium valproate. Potential properties contributing to extravasation include the following: pH, osmolarity, diluent, vasoactive properties, and inactive ingredients. Antidotes and supportive care agents used in the management of these cases of extravasation include hyaluronidase, phentolamine, terbutaline, topical anesthetics (such as lidocaine and prilocaine cream), topical antimicrobials (such as silver sulfadiazine and chlorhexidine), topical debridement agents (collagenase ointment), topical steroids, and topical vasodilators (nitroglycerin).

We evaluated whether acyclovir suppression during human immunodeficiency virus type 1 (HIV-1) acquisition reduces HIV-1 set point, increases CD4 cell counts, and selects reverse-transcriptase mutations among 76 HIV-1 seroconverters identified in a placebo-controlled trial of twice-daily acyclovir (400 mg) for the prevention of HIV acquisition in herpes simplex virus type 2 (HSV-2)-seropositive persons (HIV Prevention Trials Network study 039). We found no significant difference in plasma HIV-1 RNA levels (P =.30) or CD4 cell counts (P =.85) between the acyclovir and placebo recipients. V75I and other mutations in HIV-1 reverse transcriptase reported from in vitro acyclovir studies were not observed. In conclusion, acyclovir suppression during HIV-1 seroconversion and the subsequent 6 months does not affect HIV-1 set point.

Some clinicians claim a spontaneous complete recovery of facial nerve function after Bell's palsy in more than 80% of patients. However, for elderly patients and patients with a severe paresis/paralysis this is not the case. The main cause of Bell's palsy is probably reactivation of latent herpes viruses. Recent literature supports treatment with corticosteroids and antiviral medication, inhibiting viral replication and reducing oedema in the bony canal of the facial nerve. Using this medication in the first days of the disease provides a further 15% of patients with a good outcome in addition to the ones that improve spontaneously. Therefore, prednisone and valacyclovir are recommended for all patients with Bell's palsy and severe dysfunction, i.e. House-Brackmann facial grading scale IV, V and VI.

The survival of nude mice treated with the replication-defective adenoviral vector Ad.TK was enhanced when followed by GCV. In contrast, administration of GCV diminished the anti-tumor efficacy of the replication-competent HSV-tk expressing vectors. However, the intrinsic oncolytic effect of all replication-competent viruses was superior to that of Ad.TK+GCV. Furthermore, the oncolysis of the E1B 55-kDa-positive viruses was significantly greater than that of the E1B 55-kDa-deleted vector.

The objective of this study was to synthesize and evaluate novel enzymatically stable dipeptide prodrugs for improved absorption of acyclovir. l-Valine-l-valine-acyclovir (LLACV), l-valine-d-valine-acyclovir (LDACV), d-valine-l-valine-acyclovir (DLACV) and d-valine-d-valine-acyclovir (DDACV) were successfully synthesized. The uptake and transport studies were conducted on a Caco-2 cell line. Buffer stability and metabolism of the prodrugs in Caco-2, rat intestine and liver homogenates were studied. Structure and purity of the all compounds were confirmed with LC-MS/MS and NMR spectroscopy. Uptake and transport of [(3)H] glycylsarcosine was inhibited by all prodrugs except DDACV. DLACV and DDACV exhibited no measurable degradation in Caco-2 homogenate. Except DDACV other three prodrugs were hydrolyzed in rat intestine and liver homogenates. The order of permeability across Caco-2 was LDACV>LLACV>DDACV>DLACV. A linear correlation between the amount of prodrug transported and over all permeability of acyclovir was established. This study shows that the incorporation of one d-valine in a dipeptide did not abolish its affinity towards peptide transporters (PEPT). Moreover, it enhanced enzymatic stability of prodrug to a certain extent depending on the position in a dipeptide conjugate. This strategy improved both the cellular permeability and the amount of intact prodrug transported which would enable targeting the nutrient transporters at blood ocular barrier (BOB).

Recent outbreaks of equine herpes virus type-1 infections have stimulated renewed interest in the use of effective antiherpetic drugs in horses. The purpose of this study was to investigate the pharmacokinetics of valacyclovir (VCV), the prodrug of acyclovir (ACV), in horses. Six adult horses were used in a randomized cross-over design. Treatments consisted of 10 mg/kg ACV infused intravenously, 5 g (7.7-11.7 mg/kg) VCV delivered intragastrically (IG) and 15 g (22.7-34.1 mg/kg) VCV administered IG. Serum samples were obtained at predetermined times for acyclovir assay using high-performance liquid chromatography. Following the administration of 5 g VCV, the mean observed maximum serum ACV concentration (C(max)) was 1.45 +/- 0.38 (SD) microg/mL, at 0.74 +/- 0.43 h. At a dose of 15 g VCV, the mean C(max) was 5.26 +/- 2.82 microg/mL, at 1 +/- 0.27 h. The mean bioavailability of ACV from oral VCV was 60 +/- 12% after 5 g of VCV and 48 +/- 12% after 15 g VCV, and did not differ significantly between dose rates (P > 0.05). Superposition suggested that a loading dose of 27 mg/kg VCV every 8 h for 2 days, followed by a maintenance dose of 18 mg/kg every 12 h, will maintain effective serum ACV concentrations.

Varicella-zoster virus (VZV) pneumonitis remains an often-fatal complication of VZV infection. Antiviral agents and supportive care are widely accepted therapies. Cautious use of corticosteroids in life-threatening VZV pneumonitis may be justified. Appropriate patient selection factors are as yet unidentified and the decision to commence corticosteroid therapy in this setting is clinical.

A 6-year-old boy who had been in remission from acute lymphoblastic leukemia for 2.5 years presented with seizures, hemiparesis, visual loss, and white- and gray-matter lesions on cranial magnetic resonance imaging. The diagnosis of progressive multifocal leukoencephalopathy was established on the detection of JC virus DNA by polymerase chain reaction in brain tissue. The patient was administered several anticonvulsants, amantadine, acyclovir, and ganciclovir. He showed partial recovery. This case illustrates the possibility of long-term survival in progressive multifocal leukoencephalopathy with normal immunologic parameters.

From 2001 to 2010, 48 patients had SLE related PLE and their clinical characteristics were: age 40.8 ± 14.3 years, male-to-female ratio 1:8.6, mean symptom duration 4.3 ± 3.4 weeks, initial presentation and concomitant activity of SLE in 21(43.8%) and 37 (77.1%) patients, <20% patients developed gastrointestinal (GI) symptoms, mean serum albumin level 24.4 ± 5 g/L. Thirty (62.5%) patients had diffuse non-erosive erythematous GI mucosa with chronic inflammatory cells in lamina propria. Protein leakage was at the small bowel in 15 (31.3%) patients, terminal ileum/caecum in 16 (33.3%) patients and ascending colon in 11 (22.9%) patients. Thirty (62.5%) patients responded initially well to a combination of prednisolone and azathioprine (AZA) and 33 (68.8%) patients were maintained well by the above therapy. Higher potent induction and maintenance therapy were required in patients with: proteinuria (p < 0.01), history of previous immunosuppressive therapy (p < 0.02) and requirement of higher potent induction therapy (p < 0.01). PLE as initial SLE presentation was associated with better prognosis. Four reversible adverse events were reported: one had AZA-induced pancreatitis, two developed AZA-induced hypoplastic anemia and one developed steroid psychosis. One patient developed shingles in the fourth month and responded to oral acyclovir. No thromboembolic events were reported and one patient died of SLE nephropathy.

Cytomegalovirus (CMV) colitis is common among immunocompromised patients, and often diagnosed by pathologic confirmation because it is associated with a diverse spectrum of clinical and endoscopic features. However, Crohn's disease has no definitive diagnostic criteria, but longitudinal ulcers and cobble stone appearance are accepted as typical endoscopic features of Crohn's disease. An 83 year-old male with a history of radiotherapy for hypopharyngeal cancer visited our hospital with buy zovirax a complaint of melena for 1 week. His colonoscopic exam showed multiple longitudinal ulcers along the entire colon. Most of the ulcers were longer than 4 cm, these endoscopic findings were suspected as typical endoscopic features of Crohn's disease. Pathologic reports revealed multiple inclusion bodies with CMV on immunohistochemistry. He was finally diagnosed as having CMV colitis, and received a 3 week-course of intravenous ganciclovir. A colonoscopic follow-up showed complete healing of the multiple longitudinal ulcers, and he is doing well now without further treatment.

In cell culture, cidofovir (CDV) was used to select a human cytomegalovirus (HCMV) strain with decreased drug susceptibility. The genotypic characterization of this virus revealed a single base substitution resulting in a K513N amino acid alteration in the viral DNA polymerase (UL54). Performed in parallel, the selection of HCMV for replication in the presence of ganciclovir (GCV) selected an M460V substitution in the phosphotransferase (UL97), as well as a K513N/V812L double substitution in DNA polymerase. Neither of the two DNA polymerase mutations has been previously identified in HCMV drug-resistant strains. To precisely elucidate their role in drug resistance, corresponding recombinant mutant viruses were generated by recombination of nine overlapping viral DNA fragments. The K513N recombinant virus showed 13- and 6.5-fold decreased susceptibility to CDV and GCV in vitro, respectively, compared with the wild-type recombinant virus. Mutation V812L was associated with a moderate (2-3-fold) decrease in susceptibility to CDV, GCV, foscarnet, and adefovir. A multiplicative interaction of the K513N and V812L mutations with regard to the profile and level of drug resistance was demonstrated in recombinant virus expressing both mutations. In vitro replication kinetic experiments revealed that the K513N mutation significantly decreased HCMV replication capacity. Consistent with this finding, the K513N mutant DNA buy zovirax polymerase exhibited reduced specific activity in comparison with the wild-type enzyme and was severely impaired in its 3'-5' exonuclease function. Unexpectedly, the K513N mutant enzyme showed no decrease in susceptibility to CDV-diphosphate or GCV-triphosphate. However, the K513N mutation decreased the susceptibility to CDV and GCV of the oriLyt plasmid replication in the transient transfection/infection assay, suggesting that the DNA replication of the K513N mutant virus is less sensitive to the corresponding inhibitors.

In immunocompetent patients, HSV is controlled rapidly by the human host's immune system, and recurrent lesions are small and short lived. When treated with antiviral agents, these patients rarely develop resistance to these drugs. In contrast immunocompromised patients might not be able to control HSV infection. Thus, frequent and severe reactivations are often seen and might lead to fatal herpetic encephalitis or disseminated HSV infection. Treatment in these patients is limited because immunocompromised hosts often develop severe herpes disease refractory to antiviral drug therapy. It is therefore imperative that physicians develop regimens to deal with both receptive and refractory HSV disease. The following treatment protocol (modified from Balfour and colleagues) might serve as a guide until further investigation of new drugs is performed. In all patients standard oral ACV therapy should be initiated at a dose of 200 mg orally, five times a day for the first 3 to 5 days. Prior to treatment, cultures the lesions should be obtained to verify HSV etiology. If the response is poor, the dose of oral ACV should be increased to 800 mg five times a day. If no response seen after 5 to 7 days, it is unlikely that the lesion will respond to intravenous ACV (or chemically and structurally related drugs such as VCV or famciclovir), so an alternative regimen must be assigned. First, repeat cultures for vital, fungal, and bacterial pathogens must be performed. In addition, ACV susceptibility studies should be ordered, if available. If the mucocutaneous lesion is accessible for topical treatment, TFT (as ophthalmic solution) should be applied to the area three to four times a day until the lesion is completely healed. If the lesion is inaccessible or if the response to TFT is poor, therapy with intravenous foscarnet should be given for 10 Tegretol 200 Mg days or until complete resolution of the lesions. The dosage of foscarnet should be 40 milligrams per kilogram three times per day or 60 milligrams per kilogram twice daily. If foscarnet fails to achieve clinical clearing, consideration should be given to use of intravenous cidofovir (or application of compounded 1% to 3% topical cidofovir ointment). Vidarabine is reserved for situations in which all of these therapies fail. If lesions reoccur in the same location following clearing, the patient should started on high-dose oral ACV (800 mg, five times daily) or intravenous foscarnet (40 mg/kg tid or 60 mg/kg bid) as soon as possible. When lesions occur in a different location, the patient should be treated initially with standard doses of oral ACV (200 mg, five times daily) and the above protocol should be followed should there be clinical failure. In the future, new treatment options for patients with documented HSV resistance will be important in reducing the clinical impact of HSV.

The major findings of this study indicate that investigations into HSV-2 as a cofactor of HIV generated the political will necessary to reform HSV-2 treatment policy. Playing Requip 4 Mg a pivotal role at both the international level and within the Ghanaian policy context were 'policy networks' formed either formally (WHO) or informally (Ghana) around an issue area. These networks of professionals serve as the primary conduit of information between researchers and policy-makers. Donor influence was cited as the single strongest impetus and impediment to policy change nationally.

The mean total Knodell score of the final allograft biopsy was significantly greater in group 1 patients (P=0.016), with most of the difference due to periportal/bridging necrosis (P=0.009) and lobular activity subitem (P=0.01) scores. Half of the CMV viremic patients eventually developed allograft cirrhosis as Anafranil Cost compared with 11% of the CMV-negative patients (P=0.027). Accordingly, the cirrhosis-free actuarial survival by Kaplan-Meier estimates was significantly diminished in the CMV viremic patients. Glycoprotein B genotype analysis of CMV isolates revealed no significant differences between patients who did and those who did not develop allograft cirrhosis.

Senescent cells (SCs) accumulate with age and after genotoxic stress, such as total-body irradiation (TBI). Clearance of SCs in a progeroid mouse model using a transgenic approach delays several age-associated disorders, suggesting that SCs play a causative role in certain age-related pathologies. Thus, a 'senolytic' pharmacological agent that can selectively kill SCs holds promise for rejuvenating tissue stem cells and extending health span. To test this idea, we screened a collection of compounds and identified ABT263 (a specific inhibitor of the anti-apoptotic proteins BCL-2 and BCL-xL) as a potent senolytic drug. We show that ABT263 selectively kills SCs in culture in a cell type- and species-independent manner by inducing apoptosis. Oral administration of ABT263 to either sublethally irradiated or normally aged mice effectively depleted SCs, including senescent bone marrow hematopoietic stem cells (HSCs) and senescent Detrol Overdose Symptoms muscle stem cells (MuSCs). Notably, this depletion mitigated TBI-induced premature aging of the hematopoietic system and rejuvenated the aged HSCs and MuSCs in normally aged mice. Our results demonstrate that selective clearance of SCs by a pharmacological agent is beneficial in part through its rejuvenation of aged tissue stem cells. Thus, senolytic drugs may represent a new class of radiation mitigators and anti-aging agents.

Because of the severe complications that may result from varicella zoster virus (VZV) infection following renal transplantation (Tx), transplanted varicella-susceptible children exposed to varicella are typically given varicella zoster immunoglobulin (VZIG) as prophylaxis or are admitted and treated with parenteral acyclovir if VZIG prophylaxis fails. As both VZIG and hospitalization are costly, prevention of varicella infection by vaccination could potentially result in significant cost savings in addition to decreasing Flagyl Storage morbidity and mortality. To test this hypothesis, we developed a decision-analysis model to evaluate the cost-effectiveness of vaccinating patients with chronic renal failure (CRF) against varicella prior to renal transplant. Under baseline assumptions, vaccination for varicella pretransplant was a cost-effective strategy, with a cost of $211 per patient vaccinated compared with $1,828 per patient not vaccinated. The magnitude of cost savings from vaccination was sensitive to variations in the cost of varicella vaccine, the percentage of patients hospitalized for treatment with acyclovir, and the percentage of patients exposed to varicella infection. One- and two-way sensitivity analyses confirmed that vaccination was the dominant cost-effective strategy under all conditions examined. We conclude that vaccination for varicella pretransplant is cost-effective for patients with CRF, and that the magnitude of cost savings is sensitive to the cost of hospitalization, the percentage of patients exposed to varicella, and the cost of varicella vaccination. Pending results of ongoing studies of the safety and efficacy of VZV vaccine in children with CRF, we recommend that VZV vaccine be given to all children with CRF.

Flamel Technologies is developing Genvir (formerly known as Viropump), a twice-daily controlled-release formulation of aciclovir, for potential use in the treatment of herpes simplex virus and varicella zoster virus infections. Genvir utilizes Flamel's proprietary Micropump technology, a microparticle-based drug delivery system designed to extend the time of absorption of drugs in the small intestine. The drug shows a comparable therapeutic efficacy to valaciclovir and famciclovir (both GlaxoSmithKline) [313393]. Phase III trials have been completed [302829]. In August 2000, Flamel filed for regulatory approval for the treatment of herpes in France, as a prelude to a pan-European approval [378641] and is preparing an IND application to begin clinical trials for genital herpes in the US [245970].

Experimental brain tumor gene therapy with the herpes simplex virus thymidine kinase (HSV-tk) gene has demonstrated that not only HSV-tk transduced but surrounding non-HSV-tk transduced cells are killed when given ganciclovir. This so-called bystander effect has recently been shown to be dependent on connexin-mediated intercellular communication. To assess potential susceptibility to the bystander effect, we examined levels of connexin-26 and connexin-43 expression in a series of primary brain tumors. Connexin-26 expression has not previously been studied in primary brain tumors and connexin-43 expression has not been studied in nonastrocytic primary brain tumors. We also attempted to enhance the bystander effect in vitro by overexpressing connexin in tumor cells with high basal levels of connexin expression.

The virostatic activity of sophocarpines and gancyclovir (GCV) was tested using HHV-6 Z29 strain and Molt-3 cells. The cytotoxic (IC(50)) and the antiviral (ED(50)) values were first experimentally determined and selective indices (SI) were then calculated. The SI values for sophocarpines 1 and 2 and GCV were in the order 184, 183, and 23, respectively. Though preliminary, these findings indicate that sophocarpines have the potential to inhibit HHV-6 replication.

Herpes simplex virus is the most common cause of acute viral encephalitis in children. Due to the variety of possible clinical manifestations the diagnosis is often overlooked in the early stages of the disease. Anti-viral therapy with acyclovir should be started whenever HSE is suspected. When there is further deterioration under virostatic therapy, a brain biopsy should be performed to verify the diagnosis. But even when the adequate medical therapy is established, massive brain edema and brain shift resulting in tentorial herniation can develop. Up to now the reported mortality of these patients is still around 30%. Here we report on a child with severe necrotizing herpes simplex encephalitis who developed severe tentorial herniation due to a right-sided mass lesion. The patient's status markedly improved after decompressive anterior temporal lobe resection. To our knowledge a similar case has not yet been reported in the literature. We suggest that anterior temporal lobe resection and decompressive craniotomy is of benefit in selected cases with tentorial herniation because both decompression and reduction of infectious material can be achieved.

In cancer patients neurologic symptoms are usually due to brain metastases. This case shows that in a cancer patient any aspecific neurologic symptom should be carefully evaluated in order to exclude a non-oncologic cause. This statement is particularly true if the therapies for the oncological and neurological diseases are effective.

Corneal endotheliitis was first reported as an autoimmune disease by Khodadoust in 1982. Thereafter, herpes simplex virus (HSV) was detected as a causative agent, and corneal endotheliitis was classified as an infectious disease. However, most primary corneal endotheliitis had been idiopathic. In 2006, cytomegalovirus (CMV) DNA was detected in a case of corneal endotheliitis, and other reports on CMV endotheliitis from Asian countries established it as a new clinical entity. Limited studies have reported clinical findings, and the pathogenesis of HSV and CMV corneal endotheliitis is unknown. Therefore, this review describes what is currently known about the pathogenesis of HSV and CMV endotheliitis by way of previously reported case studies and basic research. In addition, we review work by our own group regarding the role of Toll-like receptor 9 and the results of transcriptome analysis after HSV infection in an in vitro model using immortalized human corneal endothelial cells. It is critical to diagnose corneal endotheliitis early to provide effective treatment with ganciclovir or valganciclovir and prevent the loss of corneal endothelial cells. Therefore, we hope that these in vitro results may provide further information to help elucidate the in vivo pathogenesis of HSV and CMV endotheliitis.

Oral acyclovir did not reduce the incidence of PHN significantly. There is insufficient evidence from randomised controlled trials to determine whether other antiviral treatments prevent PHN. Additional well-designed, randomised controlled trials of famciclovir or other new antiviral agents, with a greater number of participants are needed. Future trials should pay more attention to the severity of pain and quality of life of participants, and should be conducted among different subgroups of people, such as people who are immunocompromised.
