Diagnostic and therapeutic guidelines for plaque psoriasis - Brazilian Society of Dermatology.

Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

Monocyte subpopulations study in patients with plaque psoriasis.

Psoriasis is a chronic and systemic, immune-mediated, inflammatory disease, mainly manifested by skin and / or joints lesions, presenting with a wide degree of clinical severity, but generally with great impact on patients' quality of life. Despite advances in the understanding of its pathogenesis, especially regarding the participation of T-lymphocytes and the key role of TNF, the triggering factor of the disease at the molecular level remains unknown, as well as the function of other cell populations. By presenting antigens to T-lymphocytes, monocytes assume an important role in both innate and adaptive immune response. In the last two decades, by using flow cytometry with antibodies against CD14 (receptor for lipopolysaccharide) and CD16 (low affinity receptor for IgG), human blood monocytes were classified into three subpopulations: classical (CD14++CD16-), intermediate (CD14++CD16+), and non-classical (CD14+CD16++). Under normal conditions the population of classical monocytes corresponds to about 85%, while intermediate to 5.4%, and nonclassical to 9.2%. However, intermediate and nonclassical subsets are increased in various inflammatory situations, such as moderate to severe asthma, colorectal cancer, and rheumatoid arthritis. Despite psoriasis being considered a disease of inflammatory nature, scarce studies evaluating the frequency of subpopulations of monocytes in psoriatic patients are found on current medical literature, and they are restricted to peripheral blood analysis. This study aims to identify the frequency of monocyte subpopulations in blood levels as well as lesional skin of plaque psoriasis patients, and to evaluate their association to cytokines, and clinical disease severity.

Psoriasis: classical and emerging comorbidities.

Psoriasis is a chronic inflammatory systemic disease. Evidence shows an association of psoriasis with arthritis, depression, inflammatory bowel disease and cardiovascular diseases. Recently, several other comorbid conditions have been proposed as related to the chronic inflammatory status of psoriasis. The understanding of these conditions and their treatments will certainly lead to better management of the disease. The present article aims to synthesize the knowledge in the literature about the classical and emerging comorbidities related to psoriasis.

Anti-TNFα therapy in the management of psoriasis: experience of a state referral center.

BACKGROUND: Psoriasis is a chronic immune-mediated disease, characterized by increased levels of TNFα. Anti-TNFα agents have revolutionized the treatment of severe psoriasis by targeting an important molecule involved in its pathogenesis. OBJECTIVES: We report the experience of a state referral center that uses anti-TNFα agents for psoriasis. METHODS: We conducted a retrospective case series. Seventy-four out of 120 patients met the inclusion criteria. Clinical and laboratory data was analyzed using the chi-squared, Wicoxon and McNemar's tests. Associations were considered statistically significant when p-value<0.05. RESULTS: Forty-one subjects (55.40%) were male, with a mean age of 47.69 ± 14.99 years. Median disease duration and pre-treatment PASI were 14.0 months (IQR 9.0-20.0), and 13.55 points (IQR 8.5-20.32). Sixty patients (81.10%) had arthropathic psoriasis. Forty-six subjects (62.20%) had comorbidities; the most frequent was dyslipidemia (25.70%). In 55.40% of patients, insufficient response to conventional therapies was the principal indication for using anti-TNFα drugs. Clinical improvement occurred in 93.20% of cases, and the post-treatment PASI median was 0.0 points (IQR 0.0-0.0). Adverse effects occurred in 6.80% of patients. Infections and elevation of transaminases occurred in 28.40% and 8.10% of cases, respectively. CONCLUSION: Post-treatment reduction in PASI was satisfactory and the occurrence of adverse effects was minor, mostly mild infusion effects and local reactions at drug administration sites.

Inherited epidermolysis bullosa: clinical and therapeutic aspects.

Inherited epidermolysis bullosa (EB) is a heterogeneous group of genetic disorders that present with skin and, in some cases, mucosal fragility, predisposing patients to the development of blisters and/or erosions after minimal trauma or friction. Children with a recurrent history of these kinds of lesions or neonates that present them in the absence of another reasonable explanation should be investigated. Diagnosis must be based on clinical and histopathological findings. To date, management of inherited EB basically consists in avoiding traumas that trigger lesions, as well as preventing infection and facilitating healing of the wounds with the systematic use of bandages.

A epidermólise bolhosa hereditária (EBH) compreende um grupo heterogêneo de desordens genéticas que têm em comum a fragilidade cutânea e, em alguns casos mucosa, predispondo ao desenvolvimento de bolhas e/ou erosões após fricção ou trauma mínimo. Crianças com história recorrente deste tipo de lesão ou neonatos que as apresentem na ausência de outra explicação plausível devem ser investigados. O diagnóstico deve se basear em achados clínicos e histopatológicos. Até o presente momento, o manejo da EBH consiste basicamente em evitar os traumas desencadeadores das lesões, bem como evitar a infecção e facilitar a cicatrização das feridas com o uso sistemático de curativos.
