          Abstract

          Purpose

          To describe a rare case of von Szily reaction (VSR) accompanied by a comprehensive review of the literature.

          Observations

          A 57-year-old woman with herpes zoster ophthalmicus (HZO) associated with ipsilateral sectoral scleritis and anterior uveitis (sclerouveitis) subsequently developed contralateral necrotizing retinitis, leading to a diagnosis of VSR. A literature review revealed 10 additional cases of VSR. The full VSR cohort of 11 subjects included six women and five men, had a median age of 39 years (range 21–78 years), and most presented with HZO (n = 7, 63.6%), often associated with either ipsilateral anterior uveitis (n = 5; 45.5%) or keratitis (n = 4; 36.4%). All 11 cases developed necrotizing retinitis in the fellow eye, at a median of six weeks following onset in the sentinel eye. The most frequently implicated agent was varicella zoster virus (VZV; n = 8, 72.7%). A high proportion of the eight patients with VZV-associated VSR were identified as having increased risk of VZV reactivation, including age of 50 years or greater (n = 5, 62.5%), an underlying malignancy (n = 3, 37.5%), and/or use of immunosuppressive medication (n = 2, 25.0%).

          Conclusion

          This was the first reported case of VSR presenting as HZO-associated with sclerouveitis. A comprehensive literature review revealed that most previously reported cases presented with HZO associated with isolated anterior uveitis and/or keratitis, and that all reported cases of VSR developed necrotizing retinitis in the fellow eye, typically within two months of initial presentation. Patients with VZV-associated VSR often had known risk factors for VZV reactivation.

          Cytokine patterns in patients with cancer: a systematic review.

          Active, but dysfunctional, immune responses in patients with cancer have been studied in several tumour types, but owing to the heterogeneity of cancer theories of common reaction mechanisms seem to be obsolete. In this Review of published clinical studies of patients with cancer, expression and interplay of the following cytokines are examined: interleukin 2, interleukin 6, interleukin 8, interleukin 10, interleukin 12, interleukin 18, tumour necrosis factor α (TNFα), transforming growth factor β (TGFβ), interferon-γ, HLA-DR, macrophage migration inhibitory factor (MIF), and C-X-C motif chemokine receptor 4 (CXCR4). Clinical data were analysed in a non-quantitative descriptive manner and interpreted with regard to experimentally established physiological cytokine interactions. The clinical cytokine pattern that emerged suggests that simultaneous immunostimulation and immunosuppression occur in patients with cancer, with increased concentrations of the cytokines MIF, TNFα, interleukin 6, interleukin 8, interleukin 10, interleukin 18, and TGFβ. This specific cytokine pattern seems to have a prognostic effect, since high interleukin 6 or interleukin 10 serum concentrations are associated with negative prognoses in independent cancer types. Although immunostimulatory cytokines are involved in local cancer-associated inflammation, cancer cells seem to be protected from immunological eradication by cytokine-mediated local immunosuppression and a resulting defect of the interleukin 12-interferon-γ-HLA-DR axis. Cytokines produced by tumours might have a pivotal role in this defect. A working hypothesis is that the cancer-specific and histology-independent uniform cytokine cascade is one of the manifestations of the underlying paraneoplastic systemic disease, and this hypothesis links the stage of cancer with both the functional status of the immune system and the patient's prognosis. Neutralisation of this cytokine pattern could offer novel and so far unexploited treatment approaches for cancer. Copyright © 2013 Elsevier Ltd. All rights reserved.

            A population-based study of the incidence and complication rates of herpes zoster before zoster vaccine introduction.

            To establish accurate, up-to-date, baseline epidemiological data for herpes zoster (HZ) before the introduction of the recently licensed HZ vaccine. Using data from January 1, 1996, to October 15, 2005, we conducted a population-based study of adult residents (Greater than or equal to 22 years) of Olmsted County, MN, to determine (by medical record review) the incidence of HZ and the rate of HZ-related complications. Incidence rates were determined by age and sex and adjusted to the US population. A total of 1669 adult residents with a confirmed diagnosis of HZ were identified between January 1, 1996, and December 31, 2001. Most (92%) of these patients were immunocompetent and 60% were women. When adjusted to the US adult population, the incidence of HZ was 3.6 per 1000 person-years (95% confidence interval, 3.4-3.7), with a temporal increase from 3.2 to 4.1 per 1000 person-years from 1996 to 2001. The incidence of HZ and the rate of HZ-associated complications increased with age, with 68% of cases occurring in those aged 50 years and older. Postherpetic neuralgia occurred in 18% of adult patients with HZ and in 33% of those aged 79 years and older. Overall, 10% of all patients with HZ experienced 1 or more nonpain complications. Our population-based data suggest that HZ primarily affects immunocompetent adults older than 50 years; 1 in 4 experiences some type of HZ-related complication.

              T cells and aging, January 2002 update.

              Age-related changes in the immune system may contribute to morbidity and mortality due to decreased resistance to infection and, possibly, certain cancers in the aged. Many studies mostly performed in mice, rats and man but also including monkeys and dogs have established that age-associated immune decline is characterized by decreases in both humoral and cellular responses. The former may be largely a result of the latter, because observed changes both in the B cell germline-encoded repertoire and the age-associated decrease in somatic hypermutation of the B cell antigen receptors are now known to be critically affected by helper T cell aging. As antigen presenting cell (APC) function appears to be well-maintained in the elderly, this review will focus on the T cell. Factors contributing to T cell immunosenescence may include a) altered production of T cell progenitors (stem cell defects, stromal cell defects), b) decreased levels of newly-generated mature T cells (thymic involution), c) aging of resting immune cells, d) disrupted activation pathways in immune cells (stimulation via the T cell receptor for antigen, costimulation, apoptosis control), e) replicative senescence of clonally expanding cells. This review aims to consider the current state of knowledge on the scientific basis for and potential clinical relevance of those factors in immunosenescence in humans. Experiments in other species will be touched upon with the proviso that there are clearly differences between them, especially between humans and rodents, but exactly what those differences are is not completely clear. Given its potential importance and the increasing proportion of elderly people the world over, coupled with the realisation that whereas mortality is decreasing, morbidity may not be decreasing in parallel (1), a better understanding of the causes and impact of immunosenescence may offer the possibility of identifying where prevention or delay of onset, as well as therapeutic intervention, might be beneficial. Amelioration of the effects of dysregulated immune responses in the elderly by replacement therapy, supplementation therapy or other approaches may result in an enhancement of their quality of life, and significant reductions in the cost of medical care in old age.
