genetic relations between varicella-zoster virus and epstein-barr virus.varicella-zoster virus (vzv) and epstein-barr virus (ebv) are important human pathogens which belong to different subfamilies of the herpesviruses: the alpha- and gammaherpesvirinae, respectively. computer comparisons of the amino acid sequences of proteins predicted from the published complete vzv and ebv dna sequences resulted in the detection of ebv counterparts to 29 of the 67 unique vzv genes. conserved genes were detected only in the ul component of each genome, and are located in three ma ...19873033126
viral igm antibodies in serum and cerebrospinal fluid in patients with multiple sclerosis and controls.serum and cerebrospinal fluid (csf) from 28 patients with multiple sclerosis (ms), 14 with other neurological diseases (ond) and 31 control subjects with tension headache were analysed for presence of igm antibodies against measles, mumps and varicellae zoster by a specific enzyme-linked immunosorbent assay (elisa). this technique excluded false positive reaction due to possible presence of rheumatoid factor. twelve of the 28 patients with ms had igm antibodies in serum and 4 in csf, the latter ...19873033976
live attenuated varicella vaccine.live attenuated varicella vaccine will in all probability soon be licensed in the united states for immunization of healthy children and adults and certain immunocompromised children. this vaccine can be expected to protect susceptibles from varicella (or to modify it) in those subsequently exposed to the wild virus. the vaccine is safe, immunogenic, and is not associated with an increase in the incidence of zoster.19873034136
varicella-like illness caused by live varicella vaccine in children with acute lymphocytic leukemia.a varicella-like illness occurred in five of 52 children with acute lymphocytic leukemia following the administration of live varicella vaccine. only one of the children required treatment with acyclovir. virus isolated from two of the children was "vaccine-like" but differed slightly from the original vaccine strain when tested by restriction enzyme analysis. there did not appear to be a reversion to virulence because two of the household contacts who seroconverted had mild or subclinical infec ...19873035478
serum and urine concentrations of oral bromovinyldeoxyuridine in humans as monitored by a bioassay system based on varicella-zoster virus focus inhibition.a simple and sensitive bioassay method for measuring (e)-5-(2-bromovinyl)-2'-deoxyuridine (bvdu) concentrations in human serum and urine has been established. this method is based on the inhibitory effect of bvdu on varicella-zoster virus (vzv) focus formation in vitro. the minimal concentration of bvdu that could be detected in serum by this method was 0.2 microgram/ml. following a single oral administration of 250 mg bvdu, serum bvdu concentrations of 1.2-2.2 micrograms/ml were attained 1 hr l ...19873035076
the 160,000-mr virion protein encoded at the right end of the herpesvirus saimiri genome is homologous to the 140,000-mr membrane antigen encoded at the left end of the epstein-barr virus genome.the sequence of 4.4 kilobase pairs (kbp) from the conventional right terminus of the a + t-rich light-dna (l-dna) sequences of the herpesvirus saimiri (hvs) genome contains a leftward-directed open reading frame (orf) for a 1,299-residue protein. the molecular weight predicted for the protein (143,000) is in good agreement with the estimates of 150,000 to 160,000 for the major nonglycosylated polypeptide of the virion tegument (the 160k polypeptide), previously shown to be encoded by this region ...19873035208
in vitro activity of (s)-9-(3-hydroxy-2-phosphonylmethoxypropyl)adenine against newly isolated clinical varicella-zoster virus strains.the highly potent and selective anti-dna virus agent (s)-9-(3-hydroxy-2-phosphonylmethoxypropyl)adenine [(s)-hpmpa] was found to inhibit in vitro the replication of a number of clinical varicella-zoster virus strains within the concentration range of 0.63-5.7 ng/ml. with a mean 50% inhibitory concentration of 1.8 ng/ml and selectivity index of 29000, (s)-hpmpa is one of the most potent and most selective varicella-zoster virus inhibitors discovered to date.19873036498
immunological studies of uveitis. 1. immune complex containing herpes virus antigens in four patients with acute retinal necrosis syndrome.four patients with acute retinal necrosis syndrome were examined. three of them showed elevated antibody titers to varicella-zoster virus during the convalescent stage, while one of them showed an elevated titer to herpes simplex virus type 1, especially in the intraocular fluid. also, these patients had an elevated circulating immune complex in the acute phase. western blotting demonstrated that the immune complexes contained varicella-zoster or herpes simplex type 1 antigen, corresponding to t ...19863035258
varicella-zoster virus infection of human mononuclear cells.varicella-zoster virus (vzv) dna was detected in mononuclear cells (mnc) of 7 humans with acute zoster 1-23 days after the onset of skin lesions. to further study the interaction of vzv with human mnc, cells obtained from seropositive normal donors were infected with vzv and analyzed for the presence of viral dna and proteins. vzv-dna was detected in t, b, and okm 1 (monocyte-macrophage) positive cells, and virus-specific proteins were demonstrated by indirect immunofluorescence and immunoprecip ...19873035815
varicella-zoster virus as a live vector for the expression of foreign genes.the previous demonstration of the efficacy and tolerability of the oka strain of varicella-zoster virus (vzv) in clinical trials involving vaccination of both normal and immunocompromised individuals has laid the foundation for its use in preventing chickenpox. in this context, vzv could be useful as a vector for vaccinating against other infectious agents as well. as an initial application, a live recombinant vzv expressing epstein-barr virus (ebv) membrane glycoproteins (gp350/220) was generat ...19873035557
serologic detection of active infections with human herpes viruses (cmv, ebv, hsv, vzv): diagnostic potential of iga class and igg subclass-specific antibodies.in 175 sera from healthy persons as well as those suffering from primary or secondary herpes virus infections/reactivations, serum antibodies were assessed by an indirect elisa in the immunoglobulin classes a, g and m and the subclasses g1-4, using carrier-fixed antigens (cmv, vzv, hsv) and monoclonal tracer antibodies. in a similar way ebv-specific antibodies were tested by an indirect ift. only igg1 antibodies were detectable in nearly all persons. virus-specific iga and igg3 may support conve ...19873036714
varicella zoster immunoglobulin after postnatal exposure to varicella: survey of experts.a questionnaire based on a hypothetical 6-day-old infant exposed to a sibling with varicella was mailed to 316 pediatric infectious diseases society members to determine their recommendations for administration of varicella zoster immunoglobulin (vzig). of the 137 faculty members who responded 20% would recommend vzig for the infant described (13% were undecided). when further information including a negative maternal history for varicella, prematurity or maternal varicella infection occurring 1 ...19873037474

induction of antibody against in vitro translation products encoded by varicella-zoster virus glycoprotein genes.antibodies were raised in rabbit against the in vitro translation products encoded by the varicella-zoster virus (vzv) glycoprotein genes gpi and gpiv. the antisera neutralized vzv infectivity and specifically identified two late vzv glycoproteins, gpi and gpiv, in vzv-infected cells and in the envelope of vz virions. pulse-chase experiments revealed a 55k precursor protein to gpiv (60k) and a 82k precursor protein to gpi (95k). immunoprecipitation of 32p-labeled vzv-infected cells showed that t ...19873039752
varicella zoster antibody testing in the care of pregnant women exposed to varicella.appropriate use of varicella zoster immunoglobulin to prevent or ameliorate maternal or perinatal infection depends on accurate identification of varicella-susceptible women. detection of fluorescent antibody to varicella zoster virus membrane antigen is an available means for identifying women exposed to varicella who are at risk for infection. during a 5 1/2-year period, 37 pregnant women who had been exposed to varicella and who had a negative or indeterminate history of prior varicella were ...19873039845
efficacy of varicella vaccine in patients with solid tumours.thirty nine children with malignant disease and without antibodies to varicella zoster virus were immunised with a live oka strain varicella vaccine. seroconversion was shown in 24 of those who were vaccinated but five of 18 who responded to the vaccine who were followed up for over six months subsequently lost their antibodies. of 10 children who were revaccinated, nine responded to the second dose but three lost their antibodies within six months to two years. four children developed reactions ...19873039925
antibody responses to early antigens of varicella-zoster virus (vzv) during varicella and zoster.the antibody responses to membrane and early antigens and thymidine kinase of varicella-zoster virus (vzv) were studied in sera during both varicella and zoster by a test with fluorescent antibody to membrane antigen (fama), staining the biochemically transformed cells by the immunofluorescent technique and neutralization of virus-specific thymidine kinase activity, respectively. similar increases in fama antibody titers were demonstrated in sera from patients with varicella and zoster. igm was ...19863039973
perinatal viral infections.in comparison to older children and adults, neonates are immunologically incompetent. they are susceptible to infections caused by a variety of microorganisms, including bacteria, fungi and viruses. these infectious agents may be acquired by neonates either prenatally, during the intrapartum period or postnatally. the purpose of this review is to emphasize the potential impact of viral infections contracted by neonates at the time of delivery or within the neonatal period. the viruses reviewed i ...19873040392
influence of cytomegalovirus infection on the recovery of humoral immunity after autologous bone marrow transplantation.recovery of b-cell number and function was studied in 23 patients with hematological malignancies treated with high-dose chemoradiotherapy followed by autologous bone marrow transplantation (auto-bmt) in relation to the presence or absence of cytomegalovirus (cmv) infection. b cells recovered rapidly after auto-bmt and specific antibodies to herpes viruses remained nearly unchanged. both were independent of the cmv status of the patients. however, the capacity of peripheral blood b cells to diff ...19873040453
[acute viral infections in association with idiopathic peripheral facial paralysis].the possible association of some viral infections with the onset of bell's palsy was examined in a study of 29 patients. the results were compared with a sex- and age-matched control group. the number of probable recent viral infections, as judged by a fourfold increase in antibody titers or the presence of specific igm antibodies, differed statistically from that found in the control group. in seven patients with bell's palsy the enzyme-linked-immunosorbent assay (elisa) indicated an acute vira ...19873040643
structure-activity studies on synthetic peptides inhibiting herpes simplex virus ribonucleotide reductase.herpes simplex virus type 1 and type 2 (hsv-1 and hsv-2) ribonucleotide reductase is formed by the association of two nonidentical subunits. a peptide corresponding to the cooh terminus of the subunit 2, tyr-ala-gly-ala-val-val-asn-asp-leu (h2-(7-15)), has been shown to completely inhibit the reductase activity (ic50 = 36 microm) without affecting the host isoenzyme. in order to study the relationship between chemical requirements and inhibitory potencies, a series of peptides, including fragmen ...19873040743
opioid-mediated suppression of interferon-gamma production by cultured peripheral blood mononuclear cells.mounting evidence suggests that opiate addiction and stress are associated with impaired cell-mediated immunity. we tested the hypothesis that morphine and the endogenous opioid beta-endorphin (beta-end), a pituitary peptide released in increased concentrations during stress, can suppress the production of the key macrophage-activating lymphokine interferon-gamma (ifn-gamma) by cultured human peripheral blood mononuclear cells (pbmnc). using a radioimmunoassay to measure ifn-gamma, we found that ...19873040807
effect of 9-(1,3-dihydroxy-2-propoxymethyl)guanine and recombinant human beta interferon alone and in combination on simian varicella virus infection in monkeys.treatment of viral infections with combinations of antiviral agents may permit administration of reduced doses of either or both drugs. lowered doses may reduce associated toxicity. intravenous administration of substantial doses of either human recombinant beta interferon (rhuifn-beta) or 9-(1,3-dihydroxy-2-propoxymethyl)guanine (dhpg) prevents development of simian varicella virus infection in african green monkeys. daily doses of 2 x 10(6) u of rhuifn-beta/kg inhibited clinical disease in mon ...19873040868
immunization of monkeys with varicella-zoster virus glycoprotein antigens and their response to challenge with simian varicella virus.african green monkeys (cercopithecus aethiops) were immunized with three intramuscular injections of gpi, gpii, or gpiii glycoprotein antigens of varicella-zoster virus (vzv). antibody responses to vzv were determined by enzyme-linked immunosorbent assay (elisa) and to simian varicella virus (svv) by immunofluorescence and by serum neutralization assays. two weeks following the third immunization with vzv glycoproteins, the monkeys were challenged by inoculation of svv. antibodies to gpii or gpi ...19873040898
successful infection of the common marmoset (callithrix jacchus) with human varicella-zoster virus.the common marmoset, callithrix jacchus, can be infected with human varicella-zoster virus (vzv), both wild-type strain kmcc and attenuated vaccine strain oka/merck. infection was accomplished with either whole-cell-associated or cell extract vzv by combined oral-nasal-conjunctival application and was characterized by substantial and persistent anti-vzv antibody responses. the infectivity of vzv for marmosets was destroyed by treatment of inocula with heat or uv light. diluted inocula with as fe ...19873041014
varicella zoster virus infections in immunocompromised hosts. a review of the natural history and management.varicella is relatively mild in otherwise normal children, in whom new lesions form for a mean of four days after onset and heal 50 percent of their lesions in eight days. new lesions form in most immunocompromised children for longer than five days and those not treated with antiviral drugs have a 28 percent incidence of pneumonitis and a 7 percent mortality rate. untreated immunocompromised adults with herpes zoster shed virus for longer (7.0 days) than otherwise normal adults (5.3 days). herp ...19883044096
treatment of chickenpox in immunocompromised children.in hungary since 1981, 98 immunocompromised children have been treated with intravenous acyclovir for varicella zoster virus infections. they were treated in an open study or a double-blind study. results of both are discussed briefly. overall, five of 74 patients with varicella died, whereas all 24 patients with herpes zoster recovered. treatment failures occurred in patients in whom treatment started late and in those with severe lymphocytopenia. in some children, varicella zoster virus-specif ...19883044101
current therapy of varicella zoster virus infection in immunocompromised patients. a comparison of acyclovir and vidarabine.both acyclovir and vidarabine are effective treatment for varicella zoster virus (vzv) infection in immunosuppressed patients. to determine which is preferable, therapy with these two agents was compared in a prospective, randomized trial. a total of 22 immunocompromised patients undergoing treatment for hematologic malignancies and presenting with vzv infection within 72 hours of the onset of rash were randomly assigned to receive intravenous acyclovir or vidarabine; 11 patients were randomly a ...19883044102
