Disease burden, clinical management and unmet treatment need of patients with moderate to severe alopecia areata; consensus statements, insights, and practices from CERTAAE (Central/Eastern EU, Russia, Türkiye AA experts) Delphi panel.

Objectives: This study aims to update the understanding of Alopecia Areata (AA) in Poland, Czechia, Russia, and Türkiye, focusing on the disease burden, clinical management, and patient journey. It seeks to establish a consensus on optimal management strategies for AA in these regions. Methods: A modified 2-round Delphi panel was conveyed with 23 Dermatologists (Russia; 4, Türkiye; 7, Poland; 6, and Czechia; 6). The Delphi questionnaire consisted of 61 statements and 43 questions designed to obtain an overall understanding of the perception and acceptance of available information regarding the care of patients with alopecia areata. Results: The study revealed that moderate-to-severe AA significantly impacts patients' and their families' QoL, consistent with previous studies. AA was found to cause more substantial impairment when additional lesions appeared in visible areas besides the scalp. Work and productivity impairment were notably higher in adults with moderate-to-severe AA. Diagnostic consensus highlighted the importance of skin biopsies and trichoscopy, while the need for more practical severity scoring systems was emphasized. Current treatments, including topical therapies, corticosteroids, and systemic immune modifiers, were deemed insufficient, highlighting the unmet medical need. Conclusion: The Delphi study underscores a significant disease burden and unmet medical needs in patients with moderate-to-severe AA. It highlights the necessity of access to novel treatments and further research to develop more effective therapies with a tolerable safety profile. The findings align with global research, emphasizing the psychosocial impact of AA and the need for standardized, effective treatment protocols.

Differential diagnosis of contact dermatitis: A practical-approach review by the EADV Task Force on contact dermatitis.

The diagnosis of eczema ('dermatitis') is mostly clinical and depends on the clinical history and exploratory objective findings (primary lesions, patterns). Contact dermatitis remains as an important condition in the group of eczematous disorders, with important socioeconomic and occupational relevance. Although irritant and allergic contact dermatitis have a different pathogenesis, both are characterized by a rather typical morphology, are triggered by external factors and tend to occur primarily in the area of contact with the exogenous agent. In addition, allergic and irritant dermatitis may also co-exist. The importance of diagnosing contact dermatitis, especially when allergic in nature, is both due to the possibility of avoiding the trigger, and due to its role in aggravating other skin conditions. Nevertheless, the heterogeneity of clinical presentations in daily practice may pose an important challenge for the suspicion and correct diagnosis of contact dermatitis. Furthermore, other conditions, with different pathogenesis and treatment, may clinically simulate contact dermatitis. The Task Force aims to conduct a review of the unifying clinical features of contact dermatitis and characterize its main clinical phenotypes, and its simulators, in order to contribute to an early suspicion or recognition of contact dermatitis and enable a correct differential diagnosis.

PsoBarrier EU study: a Multicentre, Cross-sectional Survey Investigating the Quality of Psoriasis Care in Four European Countries.

Enhanced treatment options for psoriasis and growing use of guidelines increased the potential to better quality of psoriasis care in Europe. The aim of the PsoBarrier EU study is to compare the quality and processes of psoriasis care in four European countries with different healthcare systems, based on validated quality indicators. This cross-sectional survey was conducted in dermatology centres in Denmark, Germany, Poland and Spain on 1,304 patients, using standardized patient and physician questionnaires. Measured by quality of psoriasis care indicators, patients in Poland had the most critical outcomes, such as the highest disease severity (Psoriasis Area and Severity Index; PASI) and lowest health-related quality of life (Dermatology Life Quality Index; DLQI). This indicates differences in psoriasis care, with Polish participants experiencing more severe psoriasis and its consequences. Differences in the healthcare systems, which create barriers to accessing treatments, could explain variations in quality of care.

The Intestinal and Skin Microbiome in Patients with Atopic Dermatitis and Their Influence on the Course of the Disease: A Literature Review.

Bacteria inhabiting the digestive tract are responsible for our health. The microbiome is essential for the development of the immune system and homeostasis of the body. Maintaining homeostasis is very important, but also extremely complicated. The gut microbiome is related to the skin microbiome. It can therefore be assumed that changes in the microbes inhabiting the skin are greatly influenced by the bacteria living in the intestines. Changes in the composition and function of microbes (dysbiosis in the skin and intestines) have recently been linked to changes in the immune response and the development of skin diseases, including atopic dermatitis (AD). This review was compiled by collaborating Dermatologists specializing in atopic dermatitis and psoriasis. A comprehensive review of the current literature was performed using PubMed and limited to relevant case reports and original papers on the skin microbiome in atopic dermatitis. The inclusion criterion was that the paper was published in a peer-reviewed journal in the last 10 years (2012-2022). No limitations on the language of the publication or the type of study were made. It has been shown that any rapid changes in the composition of the microflora may be associated with the appearance of clinical signs and symptoms of the disease. Various studies have proven that the microbiome of many systems (including the intestines) may have a significant impact on the development of the inflammatory process within the skin in the course of AD. It has been shown that an early interaction between the microbiome and immune system may result in a noticeable delay in the onset of atopic diseases. It seems to be of high importance for physicians to understand the role of the microbiome in AD, not only from the pathophysiological standpoint but also in terms of the complex treatment that is required. Perhaps young children diagnosed with AD present specific characteristics of the intestinal microflora. This might be related to the early introduction of antibiotics and dietary manipulations in breastfeeding mothers in the early childhood of AD patients. It is most likely related to the abuse of antibiotics from the first days of life.

Challenges in the Diagnosis of Tertiary Syphilis: Case Report with Literature Review.

Tertiary syphilis is a large diagnostic challenge. It is rarely the case that it affects the skin, bone tissue and the eyes at the same time. The presented case shows that extensive symptomatology of syphilis poses a challenge in making a proper diagnosis in patients whose history does not suspect STDs. The study aims to present the case of a young woman hospitalized with a suspected autoimmune disease, diagnosed with symptomatic late syphilis with involvement of the skin, bones and eyes.

Possible Interdisciplinar Standard for the Care of Pregnant Women Living with HIV-Polish Experience.

HIV data for 2020 show a decline in the number and rate of new HIV cases diagnosed in the EU during the last decade. The COVID-19 pandemic has paralyzed the functioning of healthcare facilities in Poland and worldwide, also impacting the detection of HIV infection. Early diagnosis of HIV and implementation of antiretroviral treatment limit HIV transmission. A woman with HIV diagnosed during pregnancy should be under the care of a specialist in infectious diseases experienced in antiretroviral treatment. In this way, she will be properly protected during the delivery, and relevant medications can be implemented for the newborn baby. Taking these aspects into account, the medical team should consist of: A specialist in infectious diseases, an obstetrician, a neonatologist and pediatrician, a midwife, and a dermato-venereologist. Every effort should be made to increase the scope and quality of monitoring of the spread of the epidemic in Poland, with special emphasis on diagnostics based on specific tests among populations particularly exposed to HIV infections cooperating with non-governmental organizations.

The prevalence of contact hypersensitivity in patients with oral lichen planus.

Introduction: Oral lichen planus (OLP) is a chronic autoimmune inflammatory disease with an unknown aetiology and a higher prevalence in women. Oral lichenoid lesions both clinically and histologically resemble oral lichen planus and are often associated with contact allergy to dental materials. Aim: To investigate the prevalence of delayed hypersensitivity reactions in patients with OLP and to identify the most common allergens that may exacerbate the disease. Material and methods: Twenty patients diagnosed with OLP and undergoing treatment in the Gerodontology and Oral Pathology Department of the Poznan University of Medical Sciences were enrolled in the study. The subjects underwent a detailed oral examination consisting of anamnesis and a clinical evaluation by a qualified dentist, while an assessment of the skin and skin appendages was carried out by a dermatologist. Patch testing was performed using the Polish Baseline Series and Dental Screening Series. Results: Fifty percent of the examined patients displayed positive patch test reactions. A total of 18 allergic reactions were revealed, but only four appeared during the first test. The most common allergens were found to be nickel, gold, and a fragrance mix. Only 1 patient had a positive reaction to more than three allergens. Conclusions: There seems to be a high contact reaction rate in patients with oral lichen planus, which is not related to contact with synthetic dental materials. However, further investigations on a larger population with the introduction of additional tests administered 7 days after exposure are required to confirm the effects of delayed hypersensitivity reactions on patients with OLP exacerbation.

Pathogenetic aspects of chronic urticaria. Retrospective and prospective analysis of the patients of the Department of Dermatology, Poznan University of Medical Sciences.

Introduction: Urticaria is a disease with a complex pathomechanism. Confirmation of the cause in chronic urticaria seems to be a great challenge for specialists. Aim: To assess the frequency of different types of urticaria and their coexistence in 1 patient, diseases associated with chronic urticaria and the frequency of accompanying oedema. Material and methods: The study was divided into two parts. Retrospective analysis included 441 chronic urticaria patients at the age of 15 or older hospitalized in 10 years. Information from history of the disease has been placed in a specially designed form. For the prospective analysis 78 patients have been chosen out of 441 subjects previously qualified for retrospective analysis. Results: The most common type of urticaria was autoimmune (27.9% R; 30.8% P), spontaneous (19.3% R; 39.7% P) and aspirin-induced urticaria (17.5% R; 25.6% P). The most common coexisting types of urticaria were autoimmune with aspirin-induced (7.5% R; 10.3% P) and autoimmune with dermographic urticaria (3.2% R; 5.1% P). In more than half of the patients (66.7%) one type occurs only. Angioedema coexisted in over half of the patients (58% R; 69.2% P) Among the coexisting comorbidities in people with accompanying angioedema, statistically significant differences appeared in patients with thyroid diseases (19.9% with oedema and 4.9% without oedema). Among drug users, there was a greater difference between the percentage of patients with or without angioedema than among non-drug users. Conclusions: It was found that among the inducing factors - pressure and stress and among drugs taken for diseases other than urticaria - NSAIDs had an influence on the persistence of symptoms in P patients.

Insulin resistance in the course of acne - literature review.

Acne vulgaris is a very common skin disease being diagnosed in Westernized populations, however, its multifactorial etiopathogenesis still remains unclear. Recent research has demonstrated a possible linkage between acne and insulin resistance (IR), which is the topic of our review. In addition to an inappropriate diet, excessive androgen production or obesity, it is the IR which might be responsible for lack of efficacy of classical treatment strategy in acne. Interestingly, in all such cases an increased activity of mammalian target of rapamycin kinase complex 1 (mTORC1) has been detected. This observation might be considered as the basis of the possible role of metformin as an adjunct therapeutic modality for patients suffering from acne. The aim of our review is to present the possible etiological correlation between acne and insulin resistance, as well as metformin therapy, which might be highly useful in the treatment to resistant forms of acne.

Syphilis: then and now.

Getting to know the history of syphilis should begin with an attempt to establish the original source of its spread throughout the world. The dispute about the origin of syphilis, a sexually transmitted infection caused by Treponema pallidum (subspecies pallidum), had not been resolved even as late as in the twenty-first century, and to this day the supporters and opponents of the thesis that syphilis was brought to Europe by Christopher Columbus' sailors have been fighting without solid and sustainable foundations. The French named syphilis "the Neapolitan disease", while the Italians called it "the French disease".

The relationship between the severity of clinical symptoms of chronic urticaria and serum D-dimer levels.

INTRODUCTION: Urticaria and angioedema belong to a heterogeneous group of diseases and it is often very difficult to determine the specific cause of clinical symptoms. Coagulation factors play an important role, and patients with chronic urticaria have elevated plasma concentrations of coagulation factor VII, prothrombin fragment 1 + 2 and D-dimers. AIM: To assess the relationship between the severity of clinical symptoms of chronic urticaria and serum D-dimer levels. MATERIAL AND METHODS: Sixty patients with a diagnosis of chronic spontaneous urticaria, diagnosed and treated in the Dermatology Department of the Poznan University of Medical Sciences were qualified for the tests. The control group consisted of 35 healthy volunteers. All patients with chronic spontaneous urticaria were previously subjected to individual stages of the diagnostic process, in accordance with the guidelines of EAACI and the Polish team of specialists in the field of dermatology and venereology, and allergology. The dermatological condition was assessed using the UAS scale. The serum D-dimer concentration was determined by immunoturbidimetry. RESULTS: In the basic group, statistically significant, positive and high correlations between the serum D-dimer concentration and the severity of urticaria symptoms were shown, as well as between the severity of pruritus and the value of the disease activity index were shown. CONCLUSIONS: Elevated levels of D-imers are significantly correlated with the severity of urticaria.

Contemporary treatment patterns in plaque psoriasis and psoriatic arthritis.

INTRODUCTION: Psoriasis is a chronic inflammatory skin disease affecting about 2% of the general population. Although there are many treatment options, and new medications have been introduced, the disease is considered not curable, and it may seriously affect patients' quality of life. AIM: The authors present contemporary treatment patterns used by dermatologists in Poland to manage plaque psoriasis and psoriatic arthritis, particularly regarding systemic treatment. The authors also aimed to analyse how these treatment patterns are influenced by the guidelines of the Polish Dermatological Society. MATERIAL AND METHODS: The author's questionnaire, consisting of 13 questions was used. It included demographic and professional characteristics of questioned dermatologists, as well as the assessment of the attitudes towards management of plaque psoriasis and psoriatic arthritis. RESULTS: A total of 132 dermatologists completed the questionnaire. Most of the specialists worked in out-patient clinics and private practices. The most commonly used topicals for psoriasis included: glucocorticosteroids, a combination of glucocorticosteroid and vitamin D analogue and salicylic acid. Regarding the treatment of psoriatic arthritis, most of the specialists declared using systemic therapy and a combination of systemic therapy and phototherapy. The majority of the respondents were particularly concerned with possible side effects or difficulties in qualifying and monitoring the patients, and less frequently on the cost of the therapy. CONCLUSIONS: Observations suggest that 60% of physicians have some reservation to initiate systemic treatment in outpatient clinics, and they admit that they lack additional training. On the other hand, it seems also that the organization of systemic treatment in psoriasis may generate these difficulties and thus necessitate additional effort. Another factor could be the budget - not only regarding healthcare professionals, but also the patient, sometimes financing various investigations from private resources.

European Surveillance System on Contact Allergies (ESSCA): Characteristics of patients patch tested and diagnosed with irritant contact dermatitis.

BACKGROUND: Irritant contact dermatitis (ICD) is caused by the acute locally toxic effect of a strong irritant, or the cumulative exposure to various weaker physical and/or chemical irritants. OBJECTIVES: To describe the characteristics of patients with ICD in the population patch tested in the European Surveillance System on Contact Allergies (ESSCA; www.essca-dc.org) database. METHODS: Data collected by the ESSCA in consecutively patch-tested patients from January 2009 to December 2018 were analyzed. RESULTS: Of the 68 072 patients, 8702 were diagnosed with ICD (without concomitant allergic contact dermatitis [ACD]). Hand and face were the most reported anatomical sites, and 45.7% of the ICD was occupational ICD (OICD). The highest proportions of OICD were found in metal turners, bakers, pastry cooks, and confectionery makers. Among patients diagnosed with ICD, 45% were found sensitized with no relevance for the current disease. CONCLUSIONS: The hands were mainly involved in OICD also in the subgroup of patients with contact dermatitis, in whom relevant contact sensitization had been ruled out, emphasizing the need for limiting irritant exposures. However, in difficult-to-treat contact dermatitis, unrecognized contact allergy, or unrecognized clinical relevance of identified allergies owing to incomplete or wrong product ingredient information must always be considered.

Genital herpes as still significant dermatological, gynaecological and venereological problem.

Genital herpes is one of the most commonly diagnosed sexually transmitted diseases and the most common factor in the formation of ulcers and erosions within the mucous membranes. It is characterized by a wide range of clinical symptoms from serous-filled blisters located on the erythematous and oedematous substrate to asymptomatic infection. Due to anatomical differences in the genital tract, there is a more than a 4-fold increase in the risk of a woman being infected by a partner than a man by a woman. In addition, the transmission of herpes simple virus from mother to foetus becomes a serious gynaecological and neonatal problem, especially in women of childbearing age. Despite epidemiological studies, the incidence of genital herpes has not been fully understood, probably due to lack of harmonization of disease reporting systems in many countries, and to difficulties in diagnosis and treatment.

Formaldehyde 2% is not a useful means of detecting allergy to formaldehyde releasers- results of the ESSCA network, 2015-2018.

BACKGROUND: Studies suggest that patch testing with formaldehyde releasers (FRs) gives significant additional information to formaldehyde 1% aq. and should be considered for addition to the European baseline series (EBS). It is not known if this is also true for formaldehyde 2% aq. OBJECTIVES: To determine the frequency of sensitization to formaldehyde 2% aq. and co-reactivity with FRs. To establish whether there is justification for including FRs in the EBS. MATERIALS AND METHODS: A 4-year, multi-center retrospective analysis of patients with positive patch test reactions to formaldehyde 2% aq. and five FRs. RESULTS: A maximum of 15 067 patients were tested to formaldehyde 2% aq. and at least one FR. The percentage of isolated reactions to FR, without co-reactivity to, formaldehyde 2% aq. for each FR were: 46.8% for quarternium-15 1% pet.; 67.4% imidazolidinyl urea 2% pet.; 64% diazolidinyl urea 2% pet.; 83.3% 1,3-dimethylol-5, 5-dimethyl hydantoin (DMDM) hydantoin 2% pet. and 96.3% 2-bromo-2-nitropropane-1,3-diol 0.5% pet. This demonstrates that co-reactivity varies between FRs and formaldehyde, from being virtually non-existent in 2-bromo-2-nitropropane-1,3-diol 0.5% pet. (Cohen's kappa: 0, 95% confidence interval [CI] -0.02 to 0.02)], to only weak concordance for quaternium-15 [Cohen's kappa: 0.22, 95%CI 0.16 to 0.28)], where Cohen's kappa value of 1 would indicate full concordance. CONCLUSIONS: Formaldehyde 2% aq. is an inadequate screen for contact allergy to the formaldehyde releasers, which should be considered for inclusion in any series dependant on the frequency of reactions to and relevance of each individual allergen.

Patch test results with the European baseline series and additions thereof in the ESSCA network, 2015-2018.

BACKGROUND: Clinical surveillance of the prevalence of contact allergy in consecutively patch tested patients is a proven instrument to continually assess the importance of contact allergens (haptens) assembled in a baseline series. OBJECTIVES: To present current results from the European Surveillance System on Contact Allergies, including 13 countries represented by 1 to 11 departments. METHODS: Anonymized or pseudonymized patch test and clinical data from various data capture systems used locally or nationally as transferred to the Erlangen data centre were pooled and descriptively analysed after quality control. RESULTS: In the 4 years (2015-2018), data from 51 914 patients patch tested with the European baseline series (EBS) of contact allergens were analysed. Contact allergy to nickel was most frequent (17.6% positive), followed by contact allergy to fragrance mix I (6.9%), methylisothiazolinone (MI; 6.2%), and Myroxylon pereirae resin (balsam of Peru; 5.8%). CONCLUSIONS: While the prevalence of MI contact allergy decreased substantially following regulatory intervention, the persistently high levels of allergy to metals, fragrances, other preservatives, and rubber chemicals point to problems needing further research and, potentially, preventive efforts. Results with national additions to the baseline series provide important information on substances possibly to be considered for inclusion in the EBS.

Biological drugs in the treatment of atopic dermatitis - current recommendations of the Polish Dermatological Society, the Polish Society of Allergology, the Polish Pediatric Society and the Polish Society of Family Medicine.

Atopic dermatitis (AD) is secondary to genetic, immunological and microbiological disorders as well as epidermal barrier defects, which are the main targets of therapy. The disease proceeds with periodic exacerbations. Its development and course are influenced by numerous environmental and individual factors. In recent decades, in industrialized countries, there has been a threefold increase in the incidence of AD. There is also an increasing number of cases resistant to topical treatment. Effective treatment of AD should provide control of clinical symptoms, prevent exacerbations and improve the quality of life of patients. The multifactorial etiopathogenesis and various endotypes and phenotypes of AD justify the tendency to optimize and personalize the therapy. Currently, we recommend the use of dupilumab for the treatment of patients from 12 years of age with moderate and severe atopic dermatitis, who do not respond to topical treatment.
