The production of IgE specific to different viruses (HIV-1, Parvovirus B19, RSV), and the ability for IgE anti-HIV-1 to suppress HIV-1 production in vitro, strongly suggest an important role for IgE and/or anti viral specific IgE in viral pathogenesis. Previous studies in our laboratory were the first to report the presence of IgE anti-varicella zoster virus (VZV) in an adolescent patient with shingles. However, the presence and long term persistence of IgE anti VZV antibodies has not been studied in adults. The presence of serum IgE in addition to IgE and IgG anti-VZV antibody in sera were studied in children (N=12) (0-16 y/o) and adults (N=9) (32-76 y/o) with either a past history of (wild type) chicken pox (N=7 children, 9 adults) or 5 years after vaccination with varicella zoster (N=2 children) (Varicella virus vaccine live, Oka/Merck), as well as in non-infected subjects (N=3 children). Of the patients who had a positive history of chicken pox 13 of 16 (81%) contained IgE anti-VZV antibodies; they were both serum IgEHi (>100 IU/ml) and IgELo (<100 IU/ml). Of the patients who were vaccinated, IgE anti-VZV antibodies were undetected. In contrast, serum from the patients without a history of chicken pox or vaccination did not make either IgE or IgG anti-VZV antibodies. This is the first demonstration of the existence of IgE anti-VZV antibodies, and its long-term persistence in serum of previously infected subjects. Future studies regarding the functional role of anti-viral IgE and its relationship to VZV are warranted.

PURPOSE:

To provide population-based data on the risk, types, and outcomes of eye involvement in herpes zoster (HZ).

METHODS:

A cohort study based on review of the medical records of patients in whom HZ was diagnosed between January 1, 1980, and December 31, 2007, was performed. Herpes zoster was confirmed by the presence of the typical rash and symptoms or by laboratory testing, and eye involvement was confirmed by ophthalmologists' evaluation. Information was collected on all eye diagnoses and on HZ eye-related visits, treatments, procedures, and outcomes.

RESULTS:

Of the 7370 individuals with HZ in any dermatome, 184 (2.5%) had eye involvement. The mean age of the 184 was 62.6 years, and 5 cases occurred in patients younger than 21. Overall, 6.5% (12) were immunosuppressed at the time of the eye complications. The rate of increase in HZ eye involvement was 23% by decade from 1980 to 2007. Common eye complications were keratitis (n=144, 76.2%), uveitis/iritis (n=88, 46.6%), and conjunctivitis (n=67, 35.4%). Recurrent keratitis and recurrent iritis/uveitis occurred in 6.9% (13) and 7.4% (14), respectively. Outcomes included 6 patients (3.3%) with new vision decrements to 20/200 or worse. Two individuals had successful corneal transplants. Another 6 individuals (3.3%) had lid ptosis that affected vision, including 1 elderly woman with permanent unilateral tarsorrhaphy. Severe HZ eye pain was reported to be directly responsible for 1 unsuccessful suicide attempt. Acute retinal necrosis did not develop in any individual. A mean of 10.8 eye visits per patient with HZ and eye involvement was reported to continue for a mean of 308 days.

CONCLUSION:

Eye complications are common and result in considerable health care use and permanent vision decrement in about 6.6% (6) of individuals with HZ eye involvement. Most health care use and long-term adverse outcomes occurred in patients in whom prevention of HZ with the zoster vaccine would be possible.

Human alphaherpesviruses (αHHV)-herpes simplex virus type 1 (HSV-1), HSV-2, and varicella-zoster virus (VZV)-infect mucosal epithelial cells, establish a lifelong latent infection of sensory neurons, and reactivate intermittingly to cause recrudescent disease. Although chronic αHHV infections co-exist with brisk T-cell responses, T-cell immune suppression is associated with worsened recurrent infection. Induction of αHHV-specific T-cell immunity is complex and results in poly-specific CD4 and CD8 T-cell responses in peripheral blood. Specific T-cells are localized to ganglia during the chronic phase of HSV infection and to several infected areas during recurrences, and persist long after viral clearance. These recent advances hold promise in the design of new vaccine candidates.

Since 1995, many countries have been aiming to replace the natural immunity against varicella by a vaccine-induced immunity to protect against varicella and herpes zoster. While the frequency of varicella in childhood has been significantly reduced, in future, herpes zoster morbidity might increase in the elderly due to the weaker immunity post-vaccination and the absence of immunity boosting silent reinfections. In countries, where less than 90 % of children are covered by universal vaccination, varicella zoster virus (VZV) infection is not completely eradicated, but might move from childhood to the age of young adults who suffer from more serious complications. A special VZV vaccine against herpes zoster in adults aged >60 years has proven to be effective in many cases, but not all vaccinees. This might lead to problems regarding the acceptance of vaccination and delay rapid antiviral therapy to prevent the post-zosteric neuralgia. An efficacious-inactivated VZV vaccine to protect immunocompromised patients is still missing. VZV vaccines and vaccination strategies have to be optimised to avoid that the quality of life and cost savings from varicella reduction in childhood are offset by more VZV diseases in adults.

OBJECTIVE

To evaluate whether the use of personal selling, in combination with other promotional techniques, could improve patient commitment to receive the targeted intervention of herpes zoster vaccine (Zostavax-Merck). SETTING Two locally owned grocery store chain pharmacies in the Kansas City, MO, metropolitan area (Price Chopper Pharmacy 11 [PC11] and Price Chopper Pharmacy 36 [PC36]). PRACTICE DESCRIPTION Price Chopper Pharmacy employs pharmacists who are able to administer vaccinations to patients within the dispensing workflow. PRACTICE INNOVATION Passive signage promoting zoster vaccine was placed at both PC11 and PC36. Personal selling by pharmacy staff to targeted patients was implemented at PC36, where patients were encouraged to receive zoster vaccine at prescription pick up and/or by personalized letter. MAIN OUTCOME MEASURES Primary measures included comparison of the number committing to receive zoster vaccine at either pharmacy, comparison of patient perceptions regarding each pharmacy's promotion of zoster vaccine, and pharmacy staff time spent identifying targeted patients and performing personal selling activities.

RESULTS

90 of 745 targeted patients (12.1%) at PC36 made commitments to receive zoster vaccine compared with 9 of 614 (1.5%) at PC11 (P &lt; 0.001). The barrier of "Dr. hasn't told me I need it" was reduced for PC36 patients (P &lt; 0.05). Patients receiving vaccination had a more favorable attitude toward receiving zoster vaccine than unvaccinated patients (P &lt; 0.01). Among unvaccinated patients, those at PC36 had a more favorable attitude toward receiving zoster vaccine after interacting with a pharmacist (P &lt; 0.05).

CONCLUSION

Personal selling increased patient commitment to receiving a targeted intervention significantly. By using personal selling, pharmacists resolved barriers to immunization.

OBJECTIVE

To evaluate the effectiveness of community pharmacy-based interventions in increasing vaccination rates for the herpes zoster vaccine. DESIGN Prospective intervention study with a pre-post design. SETTING Three independent community pharmacies in Tennessee, from December 2007 to June 2008. PATIENTS Patients whose pharmacy profiles indicated that they were eligible for the vaccine and patients presenting to receive the vaccine at study sites. INTERVENTION Pharmacists promoted the herpes zoster vaccine through a press release published in local newspapers, a flyer accompanying each prescription dispensed at participating pharmacies, and a personalized letter mailed to patients whose pharmacy profiles indicated that they were eligible for the vaccine. MAIN OUTCOME MEASURES Comparison of vaccination rates for the herpes zoster vaccine during the control and intervention periods and patients' indication for their sources of education and influence in receiving the vaccine.

RESULTS

Vaccination rates increased from 0.37% (n = 59 of 16,121) during the control period to 1.20% (n = 193 of 16,062) during the intervention period ( P &lt; 0.0001). Cochran-Armitage trend analyses, including the months before and after the interventions, confirmed a significantly higher vaccination rate during the intervention month than other months analyzed. More patients indicated that they were educated about the herpes zoster vaccine by one of the pharmacist-driven interventions than by a physician, family/friend, or other source during the intervention period ( P &lt; 0.0001 for all comparisons). Also, more patients were influenced to receive the vaccination as a result of one of the pharmacist-driven interventions than influenced by a physician ( P = 0.0260) or other source ( P &lt; 0.0001). No difference in the effectiveness of patient influence was found when the pharmacy interventions were compared with family/friends ( P = 0.1025).

CONCLUSION

Three pharmacist-driven interventions were effective in increasing vaccination rates for the herpes zoster vaccine.

Background.

After completion of the Shingles Prevention Study (SPS; VA Cooperative Studies Program #403), SPS placebo recipients were offered investigational zoster vaccine without charge. This provided an opportunity to determine the relative safety of zoster vaccine in older adults following documented herpes zoster (HZ).Methods. SPS placebo recipients who elected to receive zoster vaccine (13,681) were followed for serious adverse events (SAE) for 28 days post-vaccination. In contrast to the SPS, a prior episode of HZ was not a contraindication to receiving zoster vaccine. The SPS placebo recipients who received zoster vaccine included 420 who had developed documented HZ during the SPS.

Results.

 The mean interval between the onset of HZ and receipt of zoster vaccine in the 420 recipients with prior HZ was 3.61 years (median 3.77 years; range 3-85 months); the interval was less than 5 years in approximately 80%. The proportion of vaccinated SPS placebo recipients with prior HZ who developed one or more SAE (0.95%) was not significantly different from that of vaccinated placebo recipients with no prior history of HZ (0.66%), and the distribution of SAE in the two groups was comparable.

Conclusions.

 These results demonstrate that the general safety of zoster vaccine in older persons is not altered by a recent history of documented HZ, supporting the safety aspect of the Centers for Disease Control and Prevention Advisory Committee on Immunization Practices recommendation to administer zoster vaccine to all persons >60 years of age with no contraindications, regardless of a prior history of HZ.

The introduction of mass vaccination against Varicella-Zoster-Virus (VZV) is being delayed in many European countries because of, among other factors, the possibility of a large increase in Herpes Zoster (HZ) incidence in the first decades after the initiation of vaccination, due to the expected decline of the boosting of Cell Mediated Immunity caused by the reduced varicella circulation. A multi-country model of VZV transmission and reactivation, is used to evaluate the possible impact of varicella vaccination on HZ epidemiology in Italy, Finland and the UK. Despite the large uncertainty surrounding HZ and vaccine-related parameters, surprisingly robust medium-term predictions are provided, indicating that an increase in HZ incidence is likely to occur in countries where the incidence rate is lower in absence of immunization, possibly due to a higher force of boosting (e.g. Finland), whereas increases in HZ incidence might be minor where the force of boosting is milder (e.g. the UK). Moreover, a convergence of HZ post vaccination incidence levels in the examined countries is predicted despite different initial degrees of success of immunization policies. Unlike previous model-based evaluations, our investigation shows that after varicella immunization an increase of HZ incidence is not a certain fact, rather depends on the presence or absence of factors promoting a strong boosting intensity and which might or not be heavily affected by changes in varicella circulation due to mass immunization. These findings might explain the opposed empirical evidences observed about the increases of HZ in sites where mass varicella vaccination is ongoing.

OBJECTIVE:

To evaluate varicella zoster virus-specific cell-mediated immunity and humoral immunogenicity against the herpes zoster vaccine, which is licensed as the Live Varicella Vaccine (Oka Strain) in Japan, in elderly people with or without diabetes mellitus.

METHODS:

A pilot study was conducted between May 2010 and November 2010 at Kitano Hospital, a general hospital in the city of Osaka in Japan. A varicella skin test, interferon-gamma enzyme-linked immunospot assay and immunoadherence hemagglutination tests were performed 0, 3, and 6 months after vaccination. Vaccine safety was also assessed using questionnaires for 42 days and development of zoster during the one-year observational period. We enrolled 10 healthy volunteers and 10 patients with diabetes mellitus aged 60-70 years.

RESULTS:

The live herpes zoster vaccine boosted virus-specific, cell-mediated and humoral immunity between elderly people, with or without diabetes. Moreover, no systemic adverse reaction was found. None of the study participants developed herpes zoster.

CONCLUSION:

The live herpes zoster vaccine was used safely. It effectively enhanced specific immunity to varicella zoster virus in older people with or without diabetes mellitus.

PubMed is not only includes international medical journals but also has a registration site for the ongoing clinical trials, such as ClinicalTrials.gov, under the supervision of US National Institutes of Health. We analyzed current status of vaccine clinical trials conducted by Korean investigators in database of ClinicalTrial.gov.As of October 2012, there are total of 72 trials found on registry of vaccine clinical trials conducted by Korean investigators in database of ClinicalTrial.gov. These trials were analyzed and classified by conditions of vaccine clinical trials, biologicals or drugs used in vaccine clinical trials, status of proceeding research, and list of sponsor and collaborators.Total 72 trials of vaccine clinical trials conducted by Korean investigators are classified by groups of infection (64 trials), cancer (4 trials), and others (4 trials). Infections group shown are as follows: poliomyelitis, pertussis, diphtheria, tetanus, and Haemophilus influenzae type b (10), influenza (9), human papillomavirus infection (8), pneumococcal vaccine (6), herpes zoster (4), smallpox (4), hepatitis B (4), etc. One trial of each in lung cancer, breast cancer, prostate cancer, and colorectal cancer are shown in cancer group. One trial of each in Crohn's disease, ulcerative colitis, renal failure, and rheumatoid arthritis are shown in other group.Vaccine clinical trials conducted by Korean investigators in ClinicalTrial.gov reflects the current status of Korean research on vaccine clinical trials at the international level and can indicate research progress. It is hoped that this aids the development of future vaccine clinical trials in Korea.
