Herpes zoster-related pain in aged individuals: How to manage it safely

Vaccination for quality of life: herpes-zoster vaccines

Current vaccination policy in most high-income countries aims to counteract the decline in cell-mediated immunity to varicella zoster virus that occurs with advancing age or immunosuppression. The aim of this review was to describe the burden of illness associated with herpes zoster (HZ) and post-herpetic neuralgia (PHN) risks and their impact on the social and common life in infected people. The effectiveness/efficacy and cost effectiveness of the immunization strategy will be presented through the review of the literature relevant to the live attenuated HZ vaccine (ZLV) licensed in 2006 and the recombinant HZ vaccine (RZV). The latter has very recently been approved to protect aged people aged ≥ 50 years against HZ morbidity including its complications, and associated health-care costs. Finally, this review also provides data with respect of precautions of using and safety of ZVL and RVZ.

Chikungunya Virus Infection: Why Should U.S. Geriatricians Be Aware of It?

Chikungunya virus (CHIKV) was until recently perceived only as a tropical disease. Since the first report of a case in Saint Martin Island in 2013, it has spread to South, Central, and North America. The first local transmission in the continental United States was reported in Florida in July 2014. CHIV infection is known to cause debilitating rheumatologic disease. Older adults are particularly susceptible to severe and chronic infection. Without an effective vaccine and antiviral therapy to prevent and control CHIKV, U.S. geriatricians could soon be confronted with major clinical, functional, and therapeutic challenges. After a general overview of CHIKV infection, this review will examine reasons why it has become such a threat to the United States and consider factors that contribute to the greater burden and effect of this disease in elderly adults. Consideration will be given to how aging and immunosenescence may contribute to CHIKV's atypical and more-severe clinical features in older adults. This review concludes with possible therapeutic approaches that best fit the unique needs of older adults, especially with regard to multimorbidity and polypharmacy.

[Recommendations for treatment and prevention of herpes zoster and associated pain in aged adults]

Initiated within the first 72 hours of the rash, prescribing antiviral drugs reduces both acute neuralgia (AN) and later complications and especially postherpetic neuralgia (PHN). But their analgesic as well as preventative effect on AN and PHN is modest. Combination with analgesic drugs is more often needed for pain management. However, the pharmacological management of pain, in the context of old patients' frailty, co-morbidities and often polypharmacy, must be carefully considered. Based on analyses of the evidences from the literature, this review presents the therapeutic options we have at one's disposal and proposes a stepwise management for both AN and PHN specifically designed for aged population.

Vaccination in the elderly: what can be recommended?

The age-associated increased susceptibility to infectious disease would suggest that vaccination should be a route to promote healthy aging and keep our seniors autonomous and independent. While vaccination represents a cost-effective and efficient strategy at community level, the ability of the immune system to mount a protective immune response is still unpredictable at the level of the individual. Thus, at a similar age, some individuals, including the elderly, might still be 'good' responders while some other, even younger, would definitely fail to mount a protective response. In this review, the current burden of vaccine-preventable diseases in the aging and aged population will be detailed with the aim to identify the ideal vaccine candidates over the age of 50 years. This article will conclude with potential strategies to reduce, as best as possible, this burden and the imperative need to overcome barriers in extending current vaccine coverage towards to a lifelong vaccine schedule.
