Abstract
BACKGROUND With an ageing society the incidences of skin diseases increase. OBJECTIVE The most important skin diseases in geriatric patients are discussed. MATERIAL AND METHODS A literature search was conducted using the PubMed database and standard dermatological textbooks. RESULTS Skin diseases in geriatric patients are often more susceptible to external influences and can be affected by visceral diseases. Due to a delayed diagnosis, malignant skin diseases in geriatric patients are first diagnosed at a higher stage. CONCLUSION Physiological skin changes are to be treated with appropriate care. In the case of unclear skin changes, a timely dermatological check-up is to be done.

Abstract
Skin aging is one of the most urgent problems that is not being studied today. The study involved 107 women with signs of age-related changes in the skin of the face aged 25 to 60 years. They were treated according to our autor’s technology neofibrolifting - autologous fibroblasts transplantation into the pretreated with platelet-rich plasma skin and ablative fractional photothermolysis procedure. The developed neofibrolifting technology allows reconstructing authentic skin structure, improving its appearance and immunity.

Abstract
The incidence of pressure ulcers is highest among older people with frailty. The development of pressure ulcers is a common and challenging issue in this population, which can reduce people's quality of life and increase mortality risk. Multifactorial processes contribute to the development of pressure ulcers in older people with frailty, including age-related skin changes, comorbidities, polypharmacy, reduced mobility, inadequate nutrition and hydration, and continence issues. This article discusses the development and management of pressure ulcers in older people with frailty. It also outlines some of the measures that can be taken by nurses and other healthcare professionals to reduce the risk of pressure ulcers developing in this population.

Abstract
The cutaneous immune response is important for the regulation of skin aging well as for the development of immune-mediated skin diseases. Aging of the human skin undergoes immunosenescence with immunological alterations and can be affected by environmental stressors and internal factors, thus leading to various epidermal barrier abnormalities. The dysfunctional epidermal barrier, immune dysregulation, and skin dysbiosis in the advanced age, together with the genetic factors, facilitate the late onset of atopic dermatitis (AD) in the elderly, whose cases have recently been on the rise. Controversial to the healthy aged skin, where overproduction of many cytokines is found, the levels of Th2/Th22 related cytokines inversely correlated with age in the skin of older AD patients. As opposed to an endogenously aged skin, the expression of the terminal differentiation markers significantly increases with age in AD. Despite the atenuated barrier disturbances in older AD patients, the aged skin carries an impairment associated with the aging process, which reflects the persistence of AD. The chronicity of AD in older patients might not directly affect skin aging but does not allow spontaneous remission. Thus, adult- and elderly subtypes of AD are considered as a lifelong disease.

Vitamin D 3 replacement enhances antigen-specific immunity in older adults. IMMUNOTHERAPY ADVANCES 2021; 1:ltaa008. [PMID: 36284901 PMCID: PMC9585673 DOI: 10.1093/immadv/ltaa008] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Revised: 11/12/2020] [Accepted: 11/19/2020] [Indexed: 12/27/2022] Open
Abstract
Introduction Ageing is associated with increased number of infections, decreased vaccine efficacy and increased systemic inflammation termed inflammageing. These changes are reflected by reduced recall responses to varicella zoster virus (VZV) challenge in the skin of older adults. Vitamin D deficiency is more common in the old and has been associated with frailty and increased inflammation. In addition, vitamin D increases immunoregulatory mechanisms and therefore has the potential to inhibit inflammageing. Objectives We investigated the use of vitamin D3 replacement to enhance cutaneous antigen-specific immunity in older adults (≥65 years). Methods Vitamin D insufficient older adults (n = 18) were administered 6400IU of vitamin D3/day orally for 14 weeks. Antigen-specific immunity to VZV was assessed by clinical score assessment of the injection site and transcriptional analysis of skin biopsies collected from challenged injection sites pre- and post-vitamin D3 replacement. Results We showed that older adults had reduced VZV-specific cutaneous immune response and increased non-specific inflammation as compared to young. Increased non-specific inflammation observed in the skin of older adults negatively correlated with vitamin D sufficiency. We showed that vitamin D3 supplementation significantly increased the response to cutaneous VZV antigen challenge in older adults. This enhancement was associated with a reduction in inflammatory monocyte infiltration with a concomitant enhancement of T cell recruitment to the site of antigen challenge in the skin. Conclusion Vitamin D3 replacement can boost antigen-specific immunity in older adults with sub-optimal vitamin D status.

Abstract
The skin is the outermost layer of the body with an extensive surface area of approximately 1·8 m2 , and is the first line of defence against a multitude of external pathogens and environmental insults. The skin also has important homeostatic functions such as reducing water loss and contributing to thermoregulation of the body. The structure of the skin and its cellular composition work in harmony to prevent infections and to deal with physical and chemical challenges from the outside world. In this review, we discuss how the structural cells such as keratinocytes, fibroblasts and adipocytes contribute to barrier immunity. We also discuss specialized immune cells that are resident in steady-state skin including mononuclear phagocytes, such as Langerhans cells, dermal macrophages and dermal dendritic cells in addition to the resident memory T cells. Ageing results in an increased incidence of cancer and skin infections. As we age, the skin structure changes with thinning of the epidermis and dermis, increased water loss, and fragmentation of collagen and elastin. In addition, the skin immune composition is altered with reduced Langerhans cells, decreased antigen-specific immunity and increased regulatory populations such as Foxp3+ regulatory T cells. Together, these alterations result in decreased barrier immunity in the elderly, explaining in part their increased susceptiblity to cancer and infections.
