Long-term exposure to low levels of ambient UVB are associated with a decreased risk of moderate-to-severe acne: A retrospective cohort study in college students. PHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE 2023; 39:132-139. [PMID: 36545686 DOI: 10.1111/phpp.12852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 11/26/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND As a crucial component of solar radiation, the association between exposure to ambient ultraviolet (UV) radiation and acne remains unclear. METHODS This was a multicenter retrospective cohort study of incoming college students in five universities of China. Previous exposure (6 years prior to enrollment) to different wavelengths of ambient UVs were obtained from public repositories by linking to individual hometown addresses. Logistic models were applied to assess the relationship between ambient UV exposure and acne. Subgroup analysis was conducted by sun protection behaviors and time of daily sun exposure. Overall effect and single effect of exposure to four different wavelengths of UVs (305, 310, 324, and 380 nm) were estimated by Bayesian kernel machine regression (BKMR). RESULTS A total of 19,939 participants was included for analysis. Analysis in all participants showed a significant association between log-transformation levels of exposure to UV at 305 nm (log (UV 305 nm)) and acne (OR = 0.77, p = .021). The effect size was stronger in participants reporting no sun protection habit. Both UVs at 305 nm (OR = 0.51, p = .001) and 310 nm (OR = 0.50, p = .012) were associated a decreased risk of acne in participants reporting no sun protection habit. This inverse association was also observed in those exposed to low levels of UV (<1 h/day). The BKMR indicated consistent results that low levels of exposure to UVs combination and UVs at 305 and 310 nm were associated with a lower risk of acne. CONCLUSION Long-term exposure to relatively low levels of ambient UVB are associated with a decreased risk of moderate-to-severe acne in college students.

Abstract
The objective of this review is to provide an update on narrowband ultraviolet B (NB-UVB) as a treatment for various skin conditions. NB-UVB works by suppressing the cutaneous cell-mediated immune response and has been shown to be an efficacious and clinically tolerable treatment for a range of inflammatory dermatoses. A literature search was conducted by advanced searches of PubMed for NB-UVB treatment of dermatologic skin diseases with a focus on reports from 2010 to 2021, including both office-based and home-based phototherapy (HBPT). Data were prioritized based on studies with a high level of evidence using the Oxford Evidence-Based Medicine guidance. We found that NB-UVB continues to serve as an effective form of therapy for several cutaneous conditions, including vitiligo, psoriasis, atopic dermatitis, mycosis fungoides, and other inflammatory dermatoses. The recent introduction of Janus kinase inhibitors in combination with NB-UVB suggests future promise in the treatment of vitiligo. Despite its rise in popularity, a decline was seen in office-based NB-UVB treatment during the coronavirus disease 2019 pandemic. Options are available to deliver NB-UVB at home with comparable efficacy to office-based treatments. In conclusion, for a select group of patients and conditions, NB-UVB continues to serve as an effective treatment modality with minimal side effects, with HBPT serving as an option to improve patient compliance.

Abstract
UV-based phototherapy (including psoralen plus UVA (PUVA), UVB and UVA1) has a long, successful history in the management of numerous cutaneous disorders. Photoresponsive diseases are etiologically diverse, but most involve disturbances in local (and occasionally systemic) inflammatory cells and/or abnormalities in keratinocytes that trigger inflammation. UV-based phototherapy works by regulating the inflammatory component and inducing apoptosis of pathogenic cells. This results in a fascinating and complex network of simultaneous events-immediate transcriptional changes in keratinocytes, immune cells, and pigment cells; the emergence of apoptotic bodies; and the trafficking of antigen-presenting cells in skin-that quickly transform the microenvironment of UV-exposed skin. Molecular elements in this system of UV recognition and response include chromophores, metabolic byproducts, innate immune receptors, neurotransmitters and mediators such as chemokines and cytokines, antimicrobial peptides, and platelet activating factor (PAF) and PAF-like molecules that simultaneously shape the immunomodulatory effects of UV and their interplay with the microbiota of the skin and beyond. Phototherapy's key effects-proapoptotic, immunomodulatory, antipruritic, antifibrotic, propigmentary, and pro-prebiotic-promote clinical improvement in various skin diseases such as psoriasis, atopic dermatitis (AD), graft-versus-host disease (GvHD), vitiligo, scleroderma, and cutaneous T-cell lymphoma (CTCL) as well as prevention of polymorphic light eruption (PLE). As understanding of phototherapy improves, new therapies (UV- and non-UV-based) are being developed that will modify regulatory T-cells (Treg), interact with (resident) memory T-cells and /or utilize agonists and antagonists as well as antibodies targeting soluble molecules such as cytokines and chemokines, transcription factors, and a variety of membrane-associated receptors.

Abstract
Psychological morbidity, sexuality, and health/system information have been identified as the highest areas of support needs in patients undergoing management of their prostate cancer (PCa). Management of a patient's sexual function prior to, during and after PCa radiotherapy requires multidisciplinary coordination of care between radiation oncologists, urologists, dermatologists, pharmacists, and psychiatrists. The finale of this three-part review provides a framework for clinicians to better understand the role of mental healthcare providers in the management of sexual toxicities associated with prostatic radiotherapy. The authors recommend that patients be referred for psychological evaluation and possibly to individual, couples or group general or cognitive behavioral sex therapy at the time of their PCa diagnosis, for a more specialized focus on management of sexual toxicities and sexual recovery. The importance and implications of the masculine self-esteem, sexual orientation, gender identification, cultural expectations, relationship status and patient education are reviewed. Well-informed patients tend to have a better quality of life outcomes compared to patients that take on a passive role in their cancer management.

The effect of low-dose isotretinoin therapy on serum androgen levels in women with acne vulgaris. Int J Womens Dermatol 2019; 6:102-104.

Abstract
Background Acne vulgaris is a common dermatologic disease that causes significant social and psychological morbidity. Isotretinoin, as a vitamin A derivative, is the most effective agent in the treatment of acne. Evidence suggests that isotretinoin’s therapeutic function is independent of hormonal mediation; however, the effect of isotretinoin on serum androgens and precursor androgen levels in humans remains unclear. Objective Herein, we aim to investigate the effect of low-dose isotretinoin on androgen levels in women and postulate the role of concomitant anti-androgen therapy (e.g., spironolactone). Methods A total of 36 women, age 18 to 30 years, with moderate-to-severe nodulocystic acne were treated with 20 mg isotretinoin (Roaccutane) daily for 3 months. A hormone panel was obtained at baseline and after completion of the treatment course. The panel included dehydroepiandrosterone (DHEA), 17-hydroxyprogestrone, testosterone, free testosterone, dihydrotestosterone (DHT), luteinizing hormone, follicle stimulating hormone, and prolactin. Results Serum levels of testosterone (p = .015), prolactin (p = .001), and DHT (p = .001) were significantly decreased, while serum levels of DHEA (p = .001) significantly increased after isotretinoin treatment. No significant change was found in the other hormones evaluated. Limitations The distribution of acne was not assessed in our patient population. We did not directly evaluate for associations between elevated DHEA levels and clinical response rates. Conclusion Isotretinoin alone can decrease androgen levels, but increase an important driver of acne pathogenesis (i.e., DHEA). The co-administration of an anti-androgenic agent (e.g., spironolactone) may optimize the therapeutic efficacy of isotretinoin by limiting iatrogenic increases in DHEA and perhaps allow for more widespread use of low-dose isotretinoin.

Abstract
Acne is a highly prevalent inflammatory skin condition involving sebaceous sties. Although it clearly develops from an interplay of multiple factors, the exact cause of acne remains elusive. It is increasingly believed that the interaction between skin microbes and host immunity plays an important role in this disease, with perturbed microbial composition and activity found in acne patients. Cutibacterium acnes (C. acnes; formerly called Propionibacterium acnes) is commonly found in sebum-rich areas and its over-proliferation has long been thought to contribute to the disease. However, information provided by advanced metagenomic sequencing has indicated that the cutaneous microbiota in acne patients and acne-free individuals differ at the virulent-specific lineage level. Acne also has close connections with the gastrointestinal tract, and many argue that the gut microbiota could be involved in the pathogenic process of acne. The emotions of stress (e.g., depression and anxiety), for instance, have been hypothesized to aggravate acne by altering the gut microbiota and increasing intestinal permeability, potentially contributing to skin inflammation. Over the years, an expanding body of research has highlighted the presence of a gut–brain–skin axis that connects gut microbes, oral probiotics, and diet, currently an area of intense scrutiny, to acne severity. This review concentrates on the skin and gut microbes in acne, the role that the gut–brain–skin axis plays in the immunobiology of acne, and newly emerging microbiome-based therapies that can be applied to treat acne.

Abstract
Acne is one of the most common skin diseases worldwide and results in major health care costs and significant morbidity to severely affected individuals. However, the pathophysiology of this disorder is not well understood. Host-microbiome interactions that affect both innate and adaptive immune homeostasis appear to be a central factor in this disease, with recent observations suggesting that the composition and activities of the microbiota in acne is perturbed. Staphylococcus epidermidis and Cutibacterium acnes (C. acnes; formerly Propionibacterium acnes) are two major inhabitants of the skin that are thought to contribute to the disease but are also known to promote health by inhibiting the growth and invasion of pathogens. Because C. acnes is ubiquitous in sebaceous-rich skin, it is typically labeled as the etiological agent of acne yet it fails to fulfill all of Koch's postulates. The outdated model of acne progression proposes that increased sebum production promotes over-proliferation of C. acnes in a plugged hair follicle, thereby driving inflammation. In contrast, growing evidence indicates that C. acnes is equally abundant in both unaffected and acne-affected follicles. Moreover, recent advances in metagenomic sequencing of the acne microbiome have revealed a diverse population structure distinct from healthy individuals, uncovering new lineage-specific virulence determinants. In this article, we review recent developments in the interactions of skin microbes with host immunity, discussing the contribution of dysbiosis to the immunobiology of acne and newly emerging skin microbiome-based therapeutics to treat acne.

Abstract
Background: Acne vulgaris is a self-limiting, chronic inflammatory disorder of the pilosebaceous unit characterized by exacerbations and remissions. It is often the early manifestation of puberty, and in girls it appears relatively early. In women, acne tends to become aggravated during the menstrual period, pregnancy, and in those who are on progesterone. Acne treatment is divided into two parts: topical and systemic. For Grades 1 and 2 acne, topical treatment is sufficient, while for Grades 3 and 4 acne, systemic drugs such as tetracyclines and retinoids are required to control the symptoms. Chemical peeling with glycolic and salicylic acids, cryosurgery with liquid nitrogen or carbon dioxide, and narrowband ultraviolet light are a few of the supportive procedural treatments available for Grades 3 and 4 acne. Objective: The author sought to determine the efficacy and safety of intense pulsed light (IPL) therapy (Magma-F-SR; FormaTK Systems, Tirat Carmel, Israel) in the treatment of Grades 3 and 4 acne as monotherapy in women of child-bearing age. Materials and Methods: One-hundred female patients with Grades 3 and 4 acne were enrolled in this study. All patients were treated with IPL using a 530nm to 1,200nm filter once a week for a total duration of six weeks. Patient and physician scores were assessed at Weeks 1 and 6 after the last treatment. Clinical photographs were also reviewed to determine the degree of efficacy. Adverse effects were noted. Results: Eighty percent of the patients involved in this study reported a significant reduction in lesion count compared to baseline. The adverse events were minimal-to-mild erythema. Conclusion: IPL therapy with 530nm to 1,200nm filter is an effective and safe modality of treatment as monotherapy in managing inflammatory Grades 3 and 4 of acne vulgaris in women of child-bearing age.

Abstract
Human skin apart from functioning as a physical barricade to stop the entry of pathogens, also hosts innumerable commensal organisms. The skin cells and the immune system constantly interact with microbes, to maintain cutaneous homeostasis, despite the challenges offered by various environmental factors. A major environmental factor affecting the skin is ultraviolet radiation (UV-R) from sunlight. UV-R is well known to modulate the immune system, which can be both beneficial and deleterious. By targeting the cells and molecules within skin, UV-R can trigger the production and release of antimicrobial peptides, affect the innate immune system and ultimately suppress the adaptive cellular immune response. This can contribute to skin carcinogenesis and the promotion of infectious agents such as herpes simplex virus and possibly others. On the other hand, a UV-established immunosuppressive environment may protect against the induction of immunologically mediated skin diseases including some of photodermatoses such as polymorphic light eruption. In this article, we share our perspective about the possibility that UV-induced immune suppression may alter the landscape of the skin’s microbiome and its components. Alternatively, or in concert with this, direct UV-induced DNA and membrane damage to the microbiome may result in pathogen associated molecular patterns (PAMPs) that interfere with UV-induced immune suppression.
