Cyclosporine‐A (Cyc‐A) was initially prescribed as systemic therapy for patients receiving solid organ transplants or in patients with graft versus host disease (GVHD). Topical Cyc‐A is an ideal form of cyclosporine in the treatment of mucocutaneous disorders as it causes fewer systemic side effects and has more stable results than steroids; however, poor absorption through the skin makes the development of new formulations necessary to improve skin permeability. The aim of this study was to evaluate the efficacy and safety of topical Cyc‐A in different dermatological conditions. A thorough systematic review was performed on PubMed/Medline, Embase, Scopus, and Web of Science databases as well as Google Scholar, and relevant studies from 2000 until January 3, 2022, were selected. The study was conducted according to the Preferred Reporting Items for Systematic reviews and Meta‐Analysis (PRISMA). Topical Cyc‐A was observed to be an effective medication in the treatment of oral lichen planus, psoriasis, burning mouth syndrome, Pyoderma Gangrenosum, and Zoon's balanitis. Adverse side effects such as dysphagia, burning sensation, lips swelling, and gastrointestinal upset were reported following Cyc‐A mouthwash use, whereas mild erythema, dryness, and fissuring of the skin were observed following the Cyc‐A lipogel application. Topical Cyc‐A was found to be a good alternative to traditional treatment regimens for immune‐mediated mucocutaneous conditions. Cyc‐A can be considered as a safe and efficient option in cases of long‐term treatment as it does not have the same adverse effects of long‐term steroids. [ABSTRACT FROM AUTHOR]

With dermatologic side effects being fairly prevalent following vaccination against COVID‐19, and the multitude of studies aiming to report and analyze these adverse events, the need for an extensive investigation on previous studies seemed urgent, in order to provide a thorough body of information about these post‐COVID‐19 immunization mucocutaneous reactions. To achieve this goal, a comprehensive electronic search was performed through the international databases including Medline (PubMed), Scopus, Cochrane, Web of science, and Google scholar on July 12, 2021, and all articles regarding mucocutaneous manifestations and considerations after COVID‐19 vaccine administration were retrieved using the following keywords: COVID‐19 vaccine, dermatology considerations and mucocutaneous manifestations. A total of 917 records were retrieved and a final number of 180 articles were included in data extraction. Mild, moderate, severe and potentially life‐threatening adverse events have been reported following immunization with COVID vaccines, through case reports, case series, observational studies, randomized clinical trials, and further recommendations and consensus position papers regarding vaccination. In this systematic review, we categorized these results in detail into five elaborate tables, making what we believe to be an extensively informative, unprecedented set of data on this topic. Based on our findings, in the viewpoint of the pros and cons of vaccination, mucocutaneous adverse events were mostly non‐significant, self‐limiting reactions, and for the more uncommon moderate to severe reactions, guidelines and consensus position papers could be of great importance to provide those at higher risks and those with specific worries of flare‐ups or inefficient immunization, with sufficient recommendations to safely schedule their vaccine doses, or avoid vaccination if they have the discussed contra‐indications.

Sucralfate is an aluminum salt of sucrose octasulfate, generally considered safe in terms of adverse effects. Systemic sucralfate is FDA‐approved for the treatment of duodenal ulcers. Since 1991, topical sucralfate has been used in various mucocutaneous conditions, but it is not approved by the FDA yet. In this systematic review, the online databases were searched with appropriate keywords, and the papers were screened by the authors. After screening steps, the relevant articles were selected according to the inclusions and exclusions criteria. Finally, the full texts of 18 articles were included for final evaluations. In conclusion, topical sucralfate has some clinical benefit in several mucocutaneous conditions, including mucocutaneous inflammatory conditions (e.g., post‐radiotherapy reaction, diaper dermatitis, keratoconjunctivitis sicca, etc.), mucocutaneous infectious disorders (e.g., peristomal wound reaction/infection); ulcers; burns, and also pain relief.

Chronic kidney disease (CKD) is a common medical problem with well‐known dermatologic manifestations, some of which highly disturb the patients' quality of life. This cross‐sectional study was designed to identify the prevalence and type of cutaneous involvement in CKD patients. The skin manifestations of 49 patients with CKD undergoing hemodialysis at Akhavan Hospital in Kashan, Iran, were recorded over 2 months. Diabetes (35%) was the most common cause of chronic renal failure in the patients, and the most common skin manifestations were xerosis (95.9%), uremic pigmentation (89.8%), scleral discoloration (87.8%), dental discoloration (85.2% among the patients with natural teeth), dry mouth (65.3%), varicosity (61.2%), pruritus (57.1%), skin atrophy (49%), lentigo (46.9%), subungual hyperkeratosis (42.9%), half and half nail dystrophy (34.7%), and purpura (26.5%). Mucocutaneous involvement has a very high prevalence in CKD patients undergoing hemodialysis, and some of the cases are medically and cosmetically disturbing; therefore, with better knowledge about the type and prevalence of these involvements, the consequences can be better predicted and managed. Further studies are recommended to be conducted on the association between these signs and CKD grade, and clinical trials are also required for establishing the treatment options available for these signs and then assessing the patients' quality of life as a primary outcome measure.

Most of drugs could have certain mucocutaneous reactions and COVID‐19 drugs are not an exception that we focused. We systematically reviewed databases until August 15, 2020 and among initial 851 articles, 30 articles entered this study (20 case reports, 4 cohorts, and 6 controlled clinical trials). The types of reactions included AGEP, morbiliform drug eruptions, vasculitis, DRESS syndrome, urticarial vasculitis, and so on. The treatments have been used before side effects occur, included: antimalarial, anti‐viral, antibiotics, tocilizumab, enoxaparin and and so on. In pandemic, we found 0.004% to 4.15% of definite drug‐induced mucocutaneous reactions. The interval between drug usage and the eruption varied about few hours to 1 month; tightly dependent to the type of drug and hydroxychloroqine seems to be the drug with highest mean interval. Antivirals, antimalarials, azithromycin, and tocilizumab are most responsive drugs for adverse drug reactions, but antivirals especially in combination with antimalarial drugs are in the first step. Types of skin reactions are usually morbilliform/exanthematous maculopapular rashes or urticarial eruptions, which mostly may manage by steroids during few days. In the setting of HCQ, specific reactions like AGEP should be considered. Lopinavir/ritonavir is the most prevalent used drug among antivirals with the highest skin adverse reaction; ribarivin and remdisivir also could induce cutaneous drug reactions but favipiravir has no or less adverse effects. Logically the rate of dermatologic adverse effects among anivirals may relate to their frequency of usage. Rarely, potentially life‐threatening reactions may occur. Better management strategies could achieve by knowing more about drug‐induced mucocutaneous presentations of COVID‐19. [ABSTRACT FROM AUTHOR]

Acitretin, a synthetic retinoid, is the pharmacologically active metabolite of etretinate. It is currently approved by the US Food and Drug Administration for the treatment of severe psoriasis in adults and has been established as a second-line therapy for the treatment of psoriasis resistant to the use of topical therapy. It is also an option for generalized pustular psoriasis, palmoplantar pustulosis, exfoliative erythrodermic psoriasis, and severe psoriasis in the setting of acitretin. It also has been shown to have chemo-preventative characteristics. Acitretin is limited by its teratogenicity and therefore considered inappropriate in most female patients of childbearing age. Common side effects include mucocutaneous dryness and elevated triglycerides. [ABSTRACT FROM AUTHOR]
