Viral reactivation following COVID-19 vaccination: a review of the current literature.

Currently, four vaccines for COVID-19 have been licensed by the European Medicines Agency: two viral vector-based vaccines and two mRNA-based vaccines. Since their approval, several cutaneous reactions related to vaccination have been reported in the literature. Among these, viral reactivations are one of the most frequent. The aim of this article was to investigate the current literature regarding viral reactivations following COVID-19 vaccination, focusing attention on pityriasis rosea (PR), herpes zoster and herpes simplex. A comprehensive literature search using various databases was performed and we included metanalyses, reviews, letters to the editor, real-life studies, case series and reports. A total of 48 articles involving 2067 patients were selected. Of these, 32, 6 and 17 articles reported varicella zoster virus (VZV) reactivation (1758 patients), herpes simplex virus (HSV) (238 patients) onset and PR (71 patients), respectively (some articles discussed more than one of these three reactivations). Possible pathogenetic mechanisms underlying viral reactivation are still not understood. Also, the possible correlations between vaccination and viral reactivation should be clarified. Certainly, vaccination should not be discouraged.

Hidradenitis Suppurativa and JAK Inhibitors: A Review of the Published Literature.

Background: Hidradenitis suppurativa (HS), also known as acne inversa or Verneuil's disease, is a chronic, inflammatory, recurrent, and debilitating skin disease of the hair follicles characterized by inflammatory, painful, deep-rooted lesions in the areas of the body characterized by the presence of the apocrine glands. Unfortunately, huge unmet needs still remain for its treatment. Objective: The purpose of our review was collecting all cases, case series, trials, and ongoing studies available in the literature on the use of this class of drugs for HS. Materials and Methods: The investigated manuscripts included trials, reviews, letters to the editor, real-life studies, case series, and reports. Manuscripts were identified, screened, and extracted for the relevant data following the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. Results: We selected 56 articles of which 25 met the selection criteria for our review. Among the JAK inhibitors to date, there is only one published clinical trial in the literature (Janus kinase 1 inhibitor INCB054707), a real-life study with 15 patients up to week 24 in which upadacitinib was used and a case series where tofacitinib was successfully used. Conversely, there are several ongoing clinical trials. Conclusions: Results to date in the literature show promising levels of efficacy and the safety of JAK inhibitors in HS. Several clinical trials are underway from which it will be very important to compare the available data. There are still too few studies conducted with a low sample size, so it remains critical to investigate this issue further in the future with a real-life study involving a large sample of patients in order to provide safe and viable therapeutic alternatives for HS.

Effect of Dupilumab on Sexual Desire in Adult Patients with Moderate to Severe Atopic Dermatitis.

Background: Atopic dermatitis (AD) is a chronic inflammatory condition causing itching skin, with a significant psychosocial impact on patients and relatives. AD affects 15 to 30% of children and 2 to 10% of adults. AD significantly affects patients' quality of life (QoL) given the chronicity and symptoms of the disease. Most AD patients have reported that the disease affects daily life, resulting in limited social contact and a strong impact on sexual health (SH), especially in moderate-severe cases. Materials and methods: We performed a prospective study from 1 May 2020 to 1 May 2022; the aim of the study was to evaluate the impact of moderate to severe AD on sexual desire, seduction, and partner relationships, and describe how it varies following dupilumab therapy. We used the Sexual Desire Inventory-2 (SDI-2), a validated instrument consisting of 14 items; moreover, we used a second questionnaire with eight items, an unvalidated instrument created specifically for this study, to obtain the assessment of the influence of AD on the body image, sexuality, and self-perception of those affected. Results and Conclusions: The impact of AD on sexual desire assessed using SDI-2 showed a significant improvement in both sexes during dupilumab treatment from the baseline to W4 and W16. Similar results were obtained with our questionnaire.
