The effect of penciclovir and acyclovir on the replication of herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) strains was determined in MRC-5 cells infected with 0.01 pfu/cell and exposed to the drugs for 72 h to allow multiple cycles of replication. Penciclovir was significantly more active than acyclovir against three strains of HSV-1 and three strains of HSV-2 at 1 mg/L (P = 0.009), 3 mg/L (P < 0.001) and 10 mg/L (P = 0.001). Further comparisons between the compounds were made in MRC-5 cells infected with HSV-1 strain SC16 using four different antiviral assays namely, the 24 h virus yield reduction assay, plaque reduction assay, viral antigen inhibition assay, and a viral DNA inhibition assay, to determine the relative merits of each. Penciclovir and acyclovir shared similar activities in the plaque reduction assay (with 50% effective concentrations, EC50, being 0.8 and 0.6 mg/L, respectively) and in the viral antigen inhibition assay (EC50s. 0.6 and 0.7 mg/L, respectively). The EC50 of penciclovir in the 24 h viral DNA inhibition assay was 0.01 mg/L compared with 0.06 mg/L of acyclovir. In the 24 h virus yield reduction assay in which MRC-5 cells were infected with 0.3 pfu/cell, penciclovir was more active than acyclovir with 99% effective concentrations of 0.6 mg/L and 1.1 mg/L, respectively. The activity of penciclovir in the 24 h virus yield reduction and antigen inhibition assays was inversely related to the multiplicity of infection, whereas this had considerably less effect on the inhibition of viral DNA synthesis. These results suggest that famciclovir, which is the oral form of penciclovir, will be at least as effective as acyclovir in treating infections caused by HSV-1 and HSV-2.

Although acute pain in patients with herpes zoster can be severe and has a substantial impact on health-related quality of life, there have been no randomized clinical trials of oral medications specifically for its ongoing treatment. A randomized clinical trial was conducted in which 87 subjects >or=50 years of age with herpes zoster within 6 calendar days of rash onset and with worst pain in the past 24h >or=3 on a 0-10 rating scale initiated 7 days of treatment with famciclovir in combination with 28 days of treatment with either controlled-release (CR) oxycodone, gabapentin, or placebo. Subjects were evaluated for adverse effects of treatment, acute pain, and health-related quality of life. The results showed that CR-oxycodone and gabapentin were generally safe and were associated with adverse events that reflect well-known effects of these medications. Discontinuing participation in the trial, primarily associated with constipation, occurred more frequently in subjects randomized to CR-oxycodone (27.6%) compared with placebo (6.9%). Treatment with CR-oxycodone reduced the mean worst pain over days 1-8 (p=0.01) and days 1-14 (p=0.02) relative to placebo but not throughout the entire 28-day treatment period as pain resolved in most subjects. Gabapentin did not provide significantly greater pain relief than placebo, although the data for the first week were consistent with a modest benefit. By demonstrating that CR-oxycodone is safe, generally adequately tolerated, and appears to have efficacy for relieving acute pain, the results of this clinical trial provide a foundation for evidence-based treatment for acute pain in herpes zoster.

The current evidence demonstrates that long-term use of oral antiviral agents can prevent HSL, but the clinical benefit is small. We did not find evidence of an increased risk of adverse events. On the other hand, the evidence on topical antiviral agents and other interventions either showed no efficacy or could not confirm their efficacy in preventing HSL.

Elephant endotheliotropic herpesvirus (EEHV) can cause lethal hemorrhagic disease in juvenile Asian elephants. A number of EEHV types and subtypes exist, where most deaths have been caused by EEHV1A and EEHV1B. EEHV4 has been attributed to two deaths, but as both diagnoses were made postmortem, EEHV4 disease has not yet been observed and recorded clinically. In this brief communication, two cases of EEHV4 infection in juvenile elephants at the Houston Zoo are described, where both cases were resolved following intensive treatment and administration of famciclovir. A quantitative real-time polymerase chain reaction detected EEHV4 viremia that correlated with clinical signs. High levels of EEHV4 shedding from trunk wash secretions of the first viremic elephant correlated with subsequent infection of the second elephant with EEHV4. It is hoped that the observations made in these cases--and the successful treatment regimen used--will help other institutions identify and treat EEHV4 infection in the future.

Acyclovir was the first antiviral drug approved for the treatment of herpes zoster. Several new antiviral agents have since been introduced, one of which is famciclovir. The pharmacokinetics of famciclovir allow a more convenient dosing schedule than the schedule used with acyclovir. Famciclovir is metabolized in the liver, but the P450 cytochrome system is not involved. Both acyclovir and famciclovir accelerate cutaneous healing, but studies suggest that famciclovir may reduce the severity of postherpetic neuralgia when compared with placebo. Famciclovir is currently approved only for use in immunocompetent patients, but clinical trials involving immunocompromised patients are in progress.

Safety reporting from individual ongoing and completed clinical studies has demonstrated that famciclovir, the well-absorbed oral form of the antiherpesvirus agent penciclovir, has been well tolerated by more than 3,000 individuals worldwide. An integrated safety evaluation has been performed and includes over 1,600 patients from 11 completed, randomized, double-blind clinical trials and 2 open trials. The famciclovir population consisted of 816 herpes zoster patients (four trials), 409 patients with acute genital herpesvirus infections (seven trials), and 382 patients from two genital herpes suppression studies. Overall, the famciclovir-treated patient population was 57.7% female and ranged in age from 15 to 102 years (mean, 42.6 years), with 31.2% aged 50 years or more and 15.7% aged 65 years or more. The mean duration of exposure to famciclovir was 28.8 days (5.8 days excluding suppression studies). The total daily doses ranged from 125 mg to 2.25 g. The most common adverse experiences reported as related to study medication (famciclovir and placebo) were headache, nausea, and diarrhea. The frequencies of adverse experiences and laboratory abnormalities (hematology, clinical chemistry, and urinalysis parameters) were similar in both famciclovir and placebo recipients. Thus, safety data from the analysis of 13 completed clinical studies demonstrate that famciclovir is tolerated well by patients with either herpes zoster or genital and has a safety profile comparable to that of placebo.

Acute viral meningitis is the most common infection of the central nervous system. Most cases occur in children and young adults and are due to enteroviruses. Although the common causes of acute viral meningitis still lack treatment with an effective antiviral agent, management of patients is changing because of better and more rapid diagnostic tests to determine the exact viral etiology. These tests reduce the cost of workups and shorten hospitalizations. Recurrent meningitis is less common, with most cases caused by herpes simplex virus 2 in young adults. Early administration of antiviral drugs such as acyclovir, valaciclovir, or famciclovir can shorten the duration of an episode of aseptic meningitis. Daily prophylactic administration of any of these medicines also reduces the frequency of future episodes.

Chemotherapy for chronic hepatitis B virus (HBV) infection is inherently difficult for a variety of reasons that are related to unusual features of both HBV replication strategy and host cell metabolism. Previous attempts to treat chronic HBV infection using nucleoside analogues have been almost universally disappointing, but several recently developed nucleoside analogues have been identified as potent, non-toxic inhibitors of HBV replication. These fall into two broad categories: nucleosides having the 'unnatural' L-configuration, and deoxyguanosine analogues with modified-sugar configurations, represented by lamivudine and penciclovir respectively. Both lamivudine and penciclovir (in its orally available form, famciclovir) have progressed to phase III clinical trials against chronic HBV infection, with promising preliminary results. However, chemotherapy for chronic HBV is necessarily long term, which increases the risks for development of viral resistance and cumulative toxicity. Such risks might be minimized by the use of appropriate drug combinations, rational selection of which requires knowledge of the pharmacokinetics and mechanisms of action of the individual agents. An appreciation of cellular deoxynucleoside metabolism and its regulation, the complexities of which are still emerging, is an indispensable aid to understanding the biological activities of deoxynucleoside analogues. The modes of action of lamividine and penciclovir, and how these two deoxynucleoside analogues may interact in vitro and in vivo as inhibitors of HBV replication, are examined here in the context of cellular deoxynucleoside metabolism.

Famciclovir 500 mg three times daily may offer an alternative to alpha-interferon for treatment for chronic hepatitis B. Anti-HBe seroconversion in the famciclovir 500-mg tid group suggests that 16 weeks treatment has the potential for HBV clearance. Further studies with a longer treatment duration are warranted.

There was no difference in the parameters representing blocking of viral production (epsilon = 93%, 95% and 86%, respectively), turnover of free virus (half-life of 16 h, 10 h and 12 h, respectively) and turnover of infected hepatocytes (half-life of 9 days, 7 days and 4 days, respectively) between the lamivudine, lamivudine-famciclovir and lamivudine-ganciclovir treatment groups.

Recurrent genital HSV outbreaks are common among those suffering from the disease. Antiviral medications taken as suppressive therapy can reduce the frequency of these recurrences and reduce viral shedding occurring in between recurrences.

Retransplantation for hepatitis B-related liver allograft failure is rarely successful. Recurrence of infection is almost universal, and the second allograft is invariably lost more rapidly than the first. In a recent multicenter study, only 1 of 20 hepatitis B virus (HBV)-positive patients who underwent liver retransplantation survived beyond 6 months. This report describes the long-term effect of antiviral therapy in a 56-year-old man who was retransplanted for HBV-related allograft loss 14 months after his initial liver transplant. He was treated after the second transplant with intravenous daily ganciclovir. After 10 months of this therapy HBV recurrence was detected. After a change to oral famciclovir therapy, there was a decrease in serum HBV DNA and amino-transferase levels and an improvement in the patient's clinical condition. Famiciclovir therapy has now been continued for 26 months, and the patient remains well 3 years after his second transplant, despite persistent HBV infection and progression to cirrhosis. These observations indicate that the use of long-term antiviral therapy offers promise for improving outcomes in patients who undergo retransplantation after HBV-related liver allograft failure.

Viral skin infections are common findings in organ transplant recipients. The most important etiological agents are the group of human herpesviruses (HHV), human papillomaviruses (HPV), and molluscum contagiosum virus. HHV that are important in this group of patients are herpes simplex virus (HSV) types 1 and 2, varicella-zoster virus (VZV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), HHV-6 and -7, and HHV-8, which causes Kaposi sarcoma (KS). HSV infections are characterized by their ability to establish latency and then reactivate at a later date. The most common manifestations of HSV infection in organ transplant recipients are mucocutaneous lesions of the oropharynx or genital regions. Treatment is usually with acyclovir, valaciclovir, or famciclovir. Acyclovir resistance may arise although the majority of acyclovir-resistant strains have been isolated from AIDS patients and not organ transplant recipients. In such cases, alternatives such as foscarnet, cidofovir, or trifluridine may have to be considered. VZV causes chickenpox as well as herpes zoster. In organ transplant recipients, recurrent herpes zoster can occur. Acute chickenpox in organ transplant patients should be treated with intravenous acyclovir. CMV infection occurs in 20-60% of all transplant recipients. Cutaneous manifestations, which include nonspecific macular rashes, ulcers, purpuric eruptions, and vesiculobullous lesions, are seen in 10-20% of patients with systemic infection and signify a poor prognosis. The present gold standard for treatment is ganciclovir, but newer drugs such as valganciclovir appear promising. EBV is responsible for some cases of post-transplant lymphoproliferative disorder, which represents the greatest risk of serious EBV disease in transplant recipients. HHV-6 and HHV-7 are two relatively newly discovered viruses and, at present, the body of information concerning these two agents is still fairly limited. KS is caused by HHV-8, which is the most recently discovered lymphotrophic HHV. Iatrogenic KS is seen in solid-organ transplant recipients, with a prevalence of 0.5-5% depending on the patient's country of origin. HPV is ubiquitous, and organ transplant recipients may never totally clear HPV infections, which are the most frequently recurring infections in renal transplant recipients. HPV infection in transplant recipients is important because of its link to the development of certain skin cancers, in particular, squamous cell carcinoma. Regular surveillance, sun avoidance, and patient education are important aspects of the management strategy.

Hepatitis B virus is a major cause of morbidity and mortality worldwide. Effective therapies were first introduced in the mid-1980s but frequent and sometimes severe side effects limit their use. Combination therapy represents the future of treatment for chronic hepatitis B, probably consisting of two or more nucleoside analogues although interferon may form part of some combinations. New drugs acting by different antiviral mechanisms may be particularly potent in combination.

Herpes simplex virus type 2 (HSV-2) resistance to antiviral drugs has been described primarily in immunocompromised patients. We report an apparently immunocompetent, human immunodeficiency virus-negative male patient who has experienced repeated HSV-2 genital outbreaks despite receiving antiviral prophylaxis with several different drugs. Several of the HSV-2 genital isolates from this patient have been confirmed as resistant to acyclovir and penciclovir. Antiviral resistance occurred in the setting of long-term prednisone treatment and intermittent acyclovir prophylaxis at suboptimal doses and persisted despite the cessation of oral steroid treatment. The patient's genital herpes outbreaks were not controlled by high-dose prophylaxis with acyclovir, valacyclovir, and famciclovir. Cessation of antiviral prophylaxis resulted in reversion of this patient's HSV-2 isolates to acyclovir and penciclovir sensitivity, although resistant virus reappeared when antiviral prophylaxis was resumed. Transmission of a sensitive HSV-2 strain from this patient to a female sex partner was observed. These observations confirm previous reports that resistance to acyclovir may develop during prophylactic therapy in an otherwise well, immunocompetent patient. These findings support the conclusion that both drug-sensitive and drug-resistant HSV-2 strains established latency in this patient and that both strains are capable of frequent reactivation.

Owing to risk of bias and inconsistency, there is low quality evidence that suppressive antiviral therapy with acyclovir, valacyclovir or famciclovir in pacients experiencing at least four recurrences of genital herpes per year decreases the number of pacients with at least one recurrence as compared with placebo. Network meta-analysis of the few direct comparisons and the indirect comparisons did not show superiority of one drug over another.

The virological profile of infection with the hepatitis B virus (HBV) is changing in many parts of the world from the classical hepatitis B e antigen (HBeAg)-positive serological pattern to a HBeAg-negative pattern, linked to the replacement of wild-type HBV by HBV variants with mutations in the core-promoter and in the precore region that prevent the secretion of HBeAg. The wild-type HBV disease is characterised by steady levels of alanine aminotransferase (ALT) and high HBV-DNA levels, responding relatively well to IFN treatment (3 - 5 MU/day or 10 MU every other day for 16 weeks), which induces anti-HBe seroconversion and normalises ALT levels in approximately 30% of the adults, with a minimal risk of relapse. Pegylated-IFN appears to have superior efficacy over conventional IFN-alpha. Mutant-type disease (anti-HBe-positive/HBeAg-negative) is less responsive to IFN given for 6 - 12 months. This has led to the use of novel nucleoside analogues, of which the prototype is lamivudine. The response to lamivudine therapy shares with IFN a rapid decline in ALT accompanied by an improvement in histology; at variance with IFN, in HBeAg-positive chronic hepatitis B (CHB) there is delayed seroconversion to anti-HBe which accumulates over time, the switch to anti-HBs is more rare and in the long-term, the activity of the drug is abolished by the emergence of viral mutations (YMDD-motif mutants) that may rekindle the disease. The combination of IFN plus lamivudine may be more efficacious than IFN or lamivudine monotherapy. Lamivudine therapy needs to be prolonged in HBeAg-negative CHB. Short-term lamivudine-therapy is highly efficacious in preventing HBV reinfection in liver transplants. Recent data suggest that long-term IFN therapy (24 months) may achieve a response in 30% of HBeAg-negative patients. The advent of adefovir, an analogue of adenosine monophosphate, may provide a safer alternative to lamivudine in the control of HBV disease; the drug is well-tolerated and treatment raises drug-resistant mutants in < 2% of the patients over 2 years of therapy. Adefovir provides rescue therapy against YMDD mutants raised by lamivudine therapy.

Liver transplantation in patients with detectable hepatitis B virus (HBV) DNA is associated with a high rate of HBV recurrence and detectable HBV DNA is often considered a contraindication for liver transplantation. Famciclovir, an oral form of the purine nucleoside penciclovir, has been shown to inhibit HBV replication. This pilot study was conducted to determine whether a 6-month course of famciclovir, administered before transplantation, was effective in inhibiting HBV replication in patients with end-stage liver disease caused by HBV and detectable HBV DNA and to assess the posttransplant clinical and virologic outcome of patients becoming HBV DNA negative with famciclovir prior to transplantation. All buy famvir eight patients enrolled were hepatitis B surface antigen (HBsAg) positive; their HBV DNA levels at baseline ranged from 4.3 to 25,321 pg/ml (mean 3,661 pg/ml). Six of the eight patients were also seropositive for HBeAg. An initial decline in HBV DNA titers occurred in all patients; however, only 25% (two of eight) of the patients became HBV DNA negative before transplantation and underwent liver transplantation. Seroconversion to hepatitis B surface antibody (HBsAb) (and HBeAb in HBeAg-positive patient) was demonstrated at the conclusion of famciclovir in the transplanted patients. Both patients remain HBV DNA negative at nearly 2 years of follow-up after transplantation. HBV DNA remained detectable in 63% (five of eight) of the patients. The mean HBV DNA level for patients who became HBV DNA negative was 5.1 pg/ml versus 424 pg/ml in nonresponders. Adverse effects attributable to famciclovir were not observed in any of the patients. Future studies should assess the predictors of response to famciclovir so that patients likely to achieve good virologic outcome can be targeted for such a therapy.

The average annual rate of HSV diagnosis declined by 31% during the course of the study.

The ability of famciclovir and valaciclovir to affect the establishment and maintenance of latency in mice with a cutaneous herpes simplex type 1 (HSV-1) infection was examined. Mice were treated via drinking water starting at various times between days 1 and 5 and terminating on day 10 after inoculation. Clinical signs and viral replication in the target tissues were monitored. Three to four months later, trigeminal and dorsal root ganglia were explanted from groups of 16 mice and examined buy famvir for latent virus by cocultivation. The two compounds differed in their effects on the acute neural infection, and ganglia explanted from famciclovir-treated mice were markedly reduced in their ability to reactivate virus, although neither drug affected latency if treatment was delayed for several months. The difference between the compounds is likely to reflect differences in the metabolism of their respective products, penciclovir and acyclovir, in infected neurons.

Penciclovir (9-[2-hydroxy-1-(hydroxymethyl)-ethoxymethyl]guanine [PCV]), lamivudine ([-]-beta-L-2',3'-dideoxy-3'-thiacytidine [3TC]), and adefovir (9-[2-phosphonylmethoxyethyl]-adenine [PMEA]) are potent inhibitors of hepatitis B virus (HBV) replication. Lamivudine has recently received approval for clinical use against chronic human HBV infection, and both PCV and PMEA have undergone clinical trials against HBV in their respective prodrug forms (famciclovir and adefovir dipivoxil [bis-(POM)-PMEA]). Since multidrug combinations are likely to be used to control HBV infection, investigation of potential interactions between PCV, 3TC, and PMEA is important. Primary duck hepatocyte cultures which were either acutely or congenitally infected with the duck hepatitis B virus (DHBV) were used to investigate in vitro interactions between PCV, 3TC, and PMEA. Here we show that the anti-DHBV effects of all the combinations containing PCV, 3TC, and PMEA are greater than that of each of the individual components and that their combined activities are approximately additive or synergistic. These results may underestimate the potential buy famvir in vivo usefulness of PMEA-containing combinations, since there is evidence that PMEA has immunomodulatory activity and, at least in the duck model of chronic HBV infection, is capable of inhibiting DHBV replication in cells other than hepatocytes, the latter being unaffected by treatment with either PCV or 3TC. Further investigation of the antiviral activities of these drug combinations is therefore required, particularly since each of the component drugs is already in clinical use.

Over the past several years there have been many advances in the diagnosis and treatment of cutaneous infectious diseases. This review focuses on the three major topics of interest in the geriatric population: herpes zoster and postherpetic neuralgia (PHN), onychomycosis, and recent buy famvir advances in antibacterial therapy. Herpes zoster in adults is caused by reactivation of the varicella-zoster virus (VZV) that causes chickenpox in children. For many years acyclovir was the gold standard of antiviral therapy for the treatment of patients with herpes zoster. Famciclovir and valacyclovir, newer antivirals for herpes zoster, offer less frequent dosing. PHN refers to pain lasting > or = 2 months after an acute attack of herpes zoster. The pain may be constant or intermittent and may occur spontaneously or be caused by seemingly innocuous stimuli such as a light touch. Treatment of established PHN through pharmacologic and nonpharmacologic therapy will be discussed. In addition, therapeutic strategies to prevent PHN will be reviewed. These include the use of oral corticosteroids, nerve blocks, and treatment with standard antiviral therapy. Onychomycosis, or tinea unguium, is caused by dermatophytes in the majority of cases, but can also be caused by Candida and nondermatophyte molds. Onychomycosis is found more frequently in the elderly and in more males than females. There are four types of onychomycosis: distal subungual onychomycosis, proximal subungual onychomycosis, white superficial onychomycosis, and candidal onychomycosis. Over the past several years, new treatments for this disorder have emerged which offer shorter courses of therapy and greater efficacy than previous therapies. The treatment of bacterial skin and skin structure infections in the elderly is an important issue. There has been an alarming increase in the incidence of gram-positive infections, including resistant bacteria such as methicillin-resistant Staphylococcus aureus (MRSA) and drug-resistant pneumococci. While vancomycin has been considered the drug of last defense against gram-positive multidrug-resistant bacteria, the late 1980s saw an increase in vancomycin-resistant bacteria, including vancomycin-resistant enterococci (VRE). More recently, strains of vancomycin-intermediate resistant S. aureus (VISA) have been isolated. Gram-positive bacteria, such as S. aureus and Streptococcus pyogenes are often the cause of skin and skin structure infections, ranging from mild pyodermas to complicated infections including postsurgical wound infections, severe carbunculosis, and erysipelas. With limited treatment options, it has become critical to identify antibiotics with novel mechanisms of activity. Several new drugs have emerged as possible therapeutic alternatives, including linezolid and quinupristin/dalfopristin.

Both famciclovir (FCV) and valaciclovir (VACV) are potent inhibitors of herpes simplex virus type 1 (HSV-1) in a murine cutaneous infection model. The object of the present study was to determine whether either drug had an effect on the anatomical distribution of infected neurons in the peripheral nervous system and to assess the consequences for infected cells during, immediately following and several months after a 9 day period of continuous treatment. Mice were inoculated via the neck with a recombinant strain of HSV-1 expressing the lacZ reporter gene under the immediate-early gene promoter. Sensory ganglia were sampled daily up to day 11 post-inoculation (p.i.) and infected cells were detected by means of the reporter gene product. Ganglia were also removed at 1.5 and buy famvir 10 months p.i. and latency was assessed by explant co-cultivation and by using in situ hybridization to detect LAT-expressing neurons. While both drugs reduced the severity of acute infection markedly, neither compound completely prevented the relentless distribution of infection among peripheral nervous tissue. Furthermore, there was a difference between the compounds regarding the expression of the reporter gene during and after termination of treatment and in the number of residual LAT-positive neurons.

Famciclovir is the oral form of the potent antiherpesvirus agent, penciclovir. Hydrolysis of one of the acetyl ester groups of famciclovir creates buy famvir a chiral centre leading to the possible formation of (R)- and (S)-enantiomers. During its conversion to penciclovir, famciclovir forms two chiral metabolites, namely monoacetyl-6-deoxy-penciclovir and monoacetyl-penciclovir. The absolute configuration and stereospecificity of the monoacetyl metabolites of famciclovir, produced in human intestinal wall extract, were determined using isotopically chiral famciclovir and 13C NMR spectroscopy of the isolated metabolites. 13C NMR showed that the esterase(s), in human intestinal wall extract, hydrolysed the acetyl group preferentially from the pro-(S)-acetoxymethyl group of famciclovir. The specificity of esterase action in forming monoacetyl-6-deoxy-penciclovir and monoacetyl-penciclovir was about 77 and 72%, respectively.

A recent meta-analysis evaluated prophylactic regimens in immunocompetent hosts, and proposed four alternatives with similar efficacies: three twice-daily regimens (i.e. acyclovir 400 mg, valaciclovir 250 mg and famciclovir 250 mg) and one once-daily regimen (valaciclovir 500 mg). Immunocompromised patients may have more prolonged, frequent and severe episodes of genital herpes. Valaciclovir 500 mg twice daily maintains the benefits of acyclovir treatment in terms of clinical efficacy and safety. Alternative therapies in case of clinical failure are discussed. Development of new strategies is moving in Nexium Mg three directions: improvement in antiviral therapy or identification of new drug targets; local immune therapy; and vaccination. Many prophylactic and therapeutic vaccination approaches have been explored, but no effective vaccine is presently available.

A multicentre, double-blind, double-placebo, randomized, parallel-design study, assessed for equivalence, was conducted. As the analysis was based on confidence intervals, a difference of lesion healing time between ACV and FCV (Delta) of 1.05 days with a standard deviation of 2.30 days was chosen. Two hundred and four outpatients were included. Patients self- Diflucan 400 Mg initiated oral therapy with 125 mg of FCV twice daily or ACV 200 mg five times daily for 5 days. The principal end-point of the study was the complete healing of lesions. Duration of the complete resolution of all symptoms, and safety were also considered.

Delineation of the pathogenic potential and assessment of the efficacy of newer therapeutic modalities for a number of viruses have been among the more notable developments in solid organ transplant infections within the past year. Infection caused by the novel herpesvirus, human herpesvirus-6, was proposed to be a significant cause of fever of unknown origin and a predictor of subsequent cytomegalovirus infection. Interleukin-2-primed isologous T lymphocytes led to the complete regression of Epstein-Barr virus-positive post-transplant lymphoproliferative disorder. Although interferon-alpha alone was shown to be largely ineffective as prophylaxis and treatment for hepatitis C virus hepatitis, the combination of interferon-alpha and ribavirin Voltaren 100mg Tablet appeared promising. Documentation within the past year, however, of lamivudine and famciclovir resistance in hepatitis B virus, ganciclovir resistance in cytomegalovirus, and azole resistance in Candida, is a sobering reminder that antimicrobial prophylaxis must be utilized rationally and selectively.

Liver transplantation in patients with hepatitis B has been under discussion for 20 years because of inferior results without reinfection prophylaxis; therefore, we analyzed our overall experience with liver transplantation in hepatitis B patients with immunoprophylaxis, particularly the influence of the available antiviral treatment in different periods. From 1988 to 2000, 228 liver transplants in 206 hepatitis B patients were performed. Indications were acute liver failure (10%), hepatitis B virus (HBV) cirrhosis alone (67%) or with hepatitis D virus (HDV) (13%), or hepatitis C virus (HCV) coinfection (7%). All patients received long-term immunoprophylaxis (anti-HBs > 100 U/L). HBV DNA-positive patients were treated before and after surgery with famciclovir or lamivudine since 1993 and 1996, respectively. Since 1993, antivirals also were used for HBV reinfection. The 1-, 5-, and 10-year patient survival rates were 91%, 81%, and 73%. In patients with hepatocellular carcinoma (HCC) (60% 5-year survival, P <.01) or HBV reinfection (69% 5-year survival, P <.01) survival was significantly impaired. Those with HDV or HCV coinfection had a slightly better survival than with HBV monoinfection (P >.05, not significant). Preoperative positive HBV DNA (hybridization-assay) test results were associated with a slightly impaired patient survival (78% 5-year survival, P >.05, not significant versus DNA-negative). Preoperative positive hepatitis B e antigen (HBeAg) predicted significantly worse survival (P <.05 versus negative HBeAg). Graft loss caused by reinfection was most Glucotrol Generic Name frequent before the availability of antiviral drugs. Two-year patient survival increased from 85% in era I (1988-1993) to 94% in era III (1997-2000, P <.05). The 2-year recurrence rates in these 2 periods were 42% and 8% (P <.05). In conclusion, excellent long-term results can be achieved in hepatitis B patients after liver transplantation with modern strategies, and survival rates are similar to other indications. Based on our experience, hepatitis B patients, including those with active viral replication, should not be excluded from liver transplantation.

Twelve patients with a history of childhood malignancy and chronic hepatitis B were treated with prednisone for 4 weeks (0.6 mg/kg body weight per day orally for 3 weeks followed by 0.3 mg/kg body weight per day for 1 week) followed by IFN-alpha-2a (5 megaunits/m(2) body surface area, three times a week, subcutaneously) at least Diovan Pills for 1 year. After 1 year of IFN-alpha monotherapy, treatment was discontinued in patients with HBeAg seroconversion as well as patients without HBeAg seroconversion and a decrease of serum hepatitis B virus (HBV) DNA level less than 0.5 logs of the basal level. Patients who had a decrease of the serum HBV DNA of more than 0.5 logs of the basal level underwent treatment continuation with IFN-alpha combined with famciclovir (FAM) (20 mg/kg body weight per day orally) for another year.
