Depression and anxiety in hidradenitis suppurativa patients: a cross-sectional study among Polish patients.

Introduction: Hidradenitis suppurativa (HS) is a chronic, recurrent and one of the most debilitating dermatoses. It usually presents with inflamed lesions in apocrine gland-bearing skin areas. There is a limited number of studies on the relationship between HS and depression as well as anxiety.

The Analysis of a Genome-Wide Association Study (GWAS) of Overweight and Obesity in Psoriasis.

There is evidence that the concomitance of psoriasis and obesity may originate from the interplay between multiple genetic pathways and involve gene−gene interactions. The aim of this study was to compare the genetic background related to obesity among psoriatic patients versus healthy controls by means of a Genome-Wide Association Study (GWAS). A total of 972 psoriatic patients and a total of 5878 healthy donors were enrolled in this study.

Generalized Pustular Psoriasis: Divergence of Innate and Adaptive Immunity.

Generalized pustular psoriasis (GPP) is a severe, relapsing, immune-mediated disease characterized by the presence of multiple sterile pustules all over the body. The exact pathomechanisms behind GPP remain elusive, although increased interest in the genetic basis and immunological disturbances have provided some revealing insights into the underlying signaling pathways and their mutual interaction. The genetic background of GPP has been thoroughly investigated over the past few years.

Acrodermatitis Continua of Hallopeau Evolving into Generalized Pustular Psoriasis Following COVID-19: A Case Report of a Successful Treatment with Infliximab in Combination with Acitretin.

The global pandemic of coronavirus disease 2019 (COVID-19) caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is emerging. Various cutaneous manifestations have been observed in patients with SARS-CoV-2 infection, yet exacerbations of psoriasis have been reported sporadically. Acrodermatitis continua of Hallopeau (ACH) is an uncommon, sterile pustular dermatosis involving one or more digits.

Pathogenesis of psoriasis in the "omic" era. Part IV. Epidemiology, genetics, immunopathogenesis, clinical manifestation and treatment of psoriatic arthritis.

Psoriatic arthritis (PsA) is a chronic, progressive, inflammatory arthropathy associated with psoriasis as well as a complex pathogenesis. Genetic and environmental factors trigger the development of the immune-mediated auto-inflammatory response in different sites: skin, bone marrow, entheses and synovial tissues. Studies of the last two decades have changed the view of PsA from a mild, non-progressive arthritis to an inflammatory systemic disease with serious health consequences, not only associated with joint dysfunction, but also with an increased risk of cardiovascular disease and socioeconomic consequences with significantly reduced quality of life.

Pathogenesis of psoriasis in the "omic" era. Part III. Metabolic disorders, metabolomics, nutrigenomics in psoriasis.

Psoriasis is a systemic disease that is strictly connected with metabolic disorders (insulin resistance, atherogenic dyslipidemia, arterial hypertension, and cardiovascular diseases). It occurs more often in patients with a more severe course of the disease. Obesity is specially an independent risk factor and it is associated with a worse treatment outcome because of the high inflammatory activity of visceral fatty tissue and the production of inflammatory mediators involved in the development of both psoriasis and metabolic disorders.

Pathogenesis of psoriasis in the "omic" era. Part II. Genetic, genomic and epigenetic changes in psoriasis.

Psoriasis is a multifactorial disease in which genetic, environmental and epigenetic factors regulating gene expression play a key role. In the "genomic era", genome-wide association studies together with target genotyping platforms performed in different ethnic populations have found more than 50 genetic susceptible markers associated with the risk of psoriasis which have been identified so far. Up till now, the strongest association with the risk of the disease has been proved for HLA-C*06 gene.

Pathogenesis of psoriasis in the "omic" era. Part I. Epidemiology, clinical manifestation, immunological and neuroendocrine disturbances.

Psoriasis is a common, chronic, inflammatory, immune-mediated skin disease affecting about 2% of the world's population. According to current knowledge, psoriasis is a complex disease that involves various genes and environmental factors, such as stress, injuries, infections and certain medications. The chronic inflammation of psoriasis lesions develops upon epidermal infiltration, activation, and expansion of type 1 and type 17 Th cells.

[Periorbital erythematous plaques and papules in an HIV-positive patient : A case report].

Prior to the introduction of antiretroviral therapy, the concomitant occurrence of sarcoidosis and human immunodeficiency virus (HIV) was extremely rare. Today, an increased prevalence of sarcoidosis as a result of immune reconstitution syndrome (IRIS) is observed in HIV patients. A 37-year-old male patient that was co-infected with HIV and hepatitis C had a 6‑month history of gradually progressive asymptomatic periorbital erythematous plaques and papules.

Quality of Life in Patients with Morphea: A Cross-Sectional Study and a Review of the Current Literature.

Objective: The aim of the study was to evaluate QoL in patients suffering from morphea. . Sixty-five patients with morphea were recruited into this cross-sectional, prospective parallel study.

Prevalence of Pruritus in Cutaneous Lupus Erythematosus: Brief Report of a Multicenter, Multinational Cross-Sectional Study.

Pruritus is an important symptom frequently accompanying various inflammatory skin conditions. Some recent data have indicated that it may also be associated with autoimmune connective tissue diseases, including systemic sclerosis and dermatomyositis; however, studies on the prevalence and clinical characteristics of pruritus in CLE are limited. We have performed a multinational, prospective, cross-sectional study in order to assess the prevalence and intensity of pruritus in adult patients suffering from various subtypes of CLE.

Disease severity and prophylactic measures in patients with cutaneous lupus erythematosus: results of a worldwide questionnaire-based study.

Introduction: Due to a wide array of dermatologic manifestations, assessment of disease severity in cutaneous lupus erythematosus (CLE) remains challenging. Given a need for some standardization in this field, we conducted a worldwide questionnaire-based study among physicians experienced in CLE management.

Aim: We asked about CLE assessment, their prophylactic measures advised to patients, and treatment recommendations.

Prevalence and Relevance of Pruritus in Pregnancy.

Pregnant women are at greater risk to suffer from chronic pruritus, but data on this symptom in this group is very limited. The aim of this study was to investigate the prevalence, clinical characteristics, and the importance of pruritus in pregnant women. A total of 292 consecutive pregnant women at the 33.

Clinical Characteristics of Pruritus and Pain in Patients with Hidradenitis Suppurativa.

A growing body of research has indicated that pruritus is an important feature of hidradenitis suppurativa (HS). This study evaluated pruritus and pain among 103 patients with HS. Pruritus and pain intensity were assessed with a visual analogue scale, numerical rating scale and 4-item Itch Questionnaire.

Trigger factors of cutaneous lupus erythematosus: a review of current literature.

It is currently believed that autoimmune conditions are triggered and aggravated by a variety of environmental factors such as cigarette smoking, infections, ultraviolet light or chemicals, as well as certain medications and vaccines in genetically susceptible individuals. Recent scientific data have suggested a relevant role of these factors not only in systemic lupus erythematosus, but also in cutaneous lupus erythematosus (CLE). A variety of environmental factors have been proposed as initiators and exacerbators of this disease.
