Positive changes in self-management and disease severity following climate therapy in people with psoriasis

The aim of this study was to investigate the impact of climate therapy on self-management in people with psoriasis. This was a prospective study of 254 adults with chronic psoriasis who participated in a 3-week climate therapy (CT) programme. The 8-scale Health Education Impact Questionnaire (heiQ) was completed at baseline, after 3 weeks of CT, and 3 months later. Change was assessed using paired sample t-tests mean (95% confidence interval) change scores (range 1-4). All heiQ scales showed statistically significant improvement after 3 weeks of CT. The greatest improvement was in Health-directed activity, followed by Emotional distress, and Skill and technique acquisition. At the 3-month follow-up, only the Emotional distress scale remained improved. In addition, disease severity (self-administered PASI; SAPASI) improved significantly from before CT to 3 weeks and 3 months after CT. This study suggests that CT provides a range of benefits that are important to people with psoriasis, particularly in the short term. A challenge is how to achieve long-term benefits.

Psoriasis: correlation between severity index (PASI) and quality of life index (DLQI) in patients assessed before and after systemic treatment

BACKGROUND: Psoriasis is a chronic inflammatory disease of the skin that affects patients of all ages and both genders. The impact of the disease on quality of life is greater among patients with moderate to severe psoriasis. OBJECTIVE: to establish a correlation between the psoriasis area and severity index (PASI) and the Dermatology Life Quality Index (DLQI) based on a quality of life questionnaire adapted to the Brazilian context for patients with plaque psoriasis before and after systemic treatment. METHODS: This was a cross-sectional, descriptive study of psoriasis patients who did not undergo treatment or who manifested clinical activity of the disease. Patients were evaluated according to the PASI and the quality of life questionnaire adapted to the Brazilian context before and 60 days after systemic treatment. RESULTS: Thirty-five patients participated in the study. Twenty-six were men, with a mean age of 46 years. There was no correlation between the PASI and the quality of life questionnaire adapted to the Brazilian context, but there was a correlation between the PASI and some items of the quality of life questionnaire adapted to the Brazilian context, such as jobs involving public contact. CONCLUSION: The non-correlation between the PASI and the quality of life questionnaire adapted to the Brazilian context in this work may be associated with a history of chronic disease, which implies greater acceptance of the illness, or may be related to the low income and social status of the patients studied. The correlation observed among patients with careers involving public contact suggests that some professions are more impacted by the disease. It may be necessary to adapt the quality of life questionnaire to patients with a low income and cultural and social limitations. The small sample size (n=35 patients) and the short follow-up period of 60 days were some of the limitations of this work.

Autoantibodies in patients with psoriasis on anti-TNFalpha therapy

Introduction: Anti-TNF-alfa therapy has been effective in the treatment of patients with refractory psoriasis and psoriasic arthritis. However, the risk of developing autoantibodies in these patients undergoing this therapy is not clear. Objective: To evaluate the induction of specific autoantibodies after anti-TNFα therapy in patients with psoriasis and psoriasic arthritis and, to evaluate the influence of the use of methotrexate on the values of autoantibodies developed during this therapy. Patients and methods: Serum samples from 120 patients, obtained before(baseline) the introduction of anti-TNF-alpha therapy and approximately each 3-6 months during the therapy.O f these 120 patients, 113 were found negative for autoantibodies before starting anti -TNFalpha therapy, 7 were found positive for ANA. The analysis included detection of antinuclear antibodies (ANA) and anti-dsDNA antibodies (indirect immunofluorescence on Hep-2 cells and Crithidia luciliae, respectively); anti extractable nuclear antigens antibodies( ENA)(ELISA). RESULTS: Infliximab is associated with the highest occurrence rate of ANA, anti-dsDNA, ENA with approximately 69,2%, 11,5%, 7,6% of patients treated testing positive. In comparison, only 20%, 6,6%, 2,2% of patients treated with Adalimumab, and 19%, 2,3%, 2,3% of patients treated with Etanercept were positive for ANA, Anti-dsDNA, ENA respectively. As regard the seven patients who were positive at baseline, six of them (85.7%) in addition to being remained positive during the therapy they have also increased the autoantibodies ’s titers. Conclusion: our study have shown that Infliximab is associated with the highest rate of autoantibodies. The concomitant treatment with methotrexate did not modify the titers of autoantibodies developed during the therapy anti-TNFalph. The incidence of ANA, anti-dsDNA antibodies did not correlate with development of Lupus-like syndromes. The difference in the frequency of autoantibodies between psoriasis and psoriatic arthritis was not statistically significant (p = 0.867).

Efficacy and safety of the Betamethasone valerate 0.1% plaster in mild-to-moderate chronic plaque psoriasis: a randomized, parallel-group, active-controlled, phase III study

Corticosteroids are a versatile option for the treatment of mild-to-moderate psoriasis due to their availability in a wide range of potencies and formulations. Occlusion of the corticosteroid is a widely accepted procedure to enhance the penetration of the medication, thereby improving its effectiveness. Betamethasone valerate (BMV) is a moderately potent corticosteroid that is available as a cream, ointment, and lotion. A ready-to-use occlusive dressing, which provides a continuous sustained release of BMV, has been developed for the treatment of psoriasis.

Rapid downregulation of innate immune cells, interleukin-12 and interleukin-23 in generalized pustular psoriasis with infliximab in combination with acitretin

Generalized pustular psoriasis (GPP) is a severe inflammatory disease characterized by recurrent eruptions of sterile pustules on erythematous skin. Although tumor necrosis factor (TNF) antagonists may lead to a rapid resolution of GPP, the mechanism of action of these agents remains to be investigated. Here, we sought to evaluate markers of immune response in the skin of a patient who experienced a rapid amelioration of GPP after treatment with infliximab and acitretin.

The effect of different pulse durations in the treatment of nail psoriasis with 595-nm pulsed dye laser: a randomized, double-blind, intrapatient left-to-right study

Several studies have proven the efficacy of pulsed dye laser (PDL) in the treatment of plaque type psoriasis. However, only two published studies indicate the effectiveness of PDL on nail psoriasis.

Marked improvement in nail psoriasis during treatment with adalimumab

BACKGROUND: Nail involvement is known as a common finding in psoriatic patients and represents a significant impact on patients' quality of life. The treatment of nail psoriasis is often challenging, and there is a need for new therapeutic options. Biologicals effective in the treatment of moderate to severe chronic plaque psoriasis may represent a new therapeutic modality for this disease. Adalimumab is a fully human IgG1 monoclonal antibody that binds to tumor necrosis factor alpha with high affinity and specificity. OBSERVATIONS: We report two cases of rapid improvement in nail psoriasis under adalimumab monotherapy with maintained effectiveness despite intermittent treatment as well as long remission after therapy discontinuation. CONCLUSION: The marked improvement of our two cases indicates that adalimumab may also help ameliorate nail psoriasis and warrants further controlled studies to establish the effectiveness and therapeutic regimes.

A comparative study of the expression of cytotoxic proteins in allergic contact dermatitis and psoriasis: spongiotic skin lesions in allergic contact dermatitis are highly infiltrated by T cells expressing perforin and granzyme B

Recent reports indicate that cytotoxic T cells are critically involved in contact hypersensitivity reactions in animals. In this study we sought to investigate the in vivo expression of cytotoxic granule proteins in the elicitation phase of allergic contact dermatitis in humans. Skin biopsy specimens were obtained from patients with allergic contact dermatitis (n = 8) and psoriasis (n = 6) and from controls with normal skin (n = 6). Expression of perforin and granzyme B was investigated by in situ hybridization and immunohistochemistry. In contrast to normal skin and psoriasis, a significant enhancement of perforin and granzyme B gene expression and immunoreactivity was observed in the mononuclear cell infiltrate of allergic contact dermatitis. Immunoreactivity for perforin and granzyme B was mainly found in the cytoplasm of lymphocytic cells, which were located in the dense perivascular infiltrate as well as at sites of marked spongiosis in the epidermis. Double immunostaining revealed that both CD4+ and CD8+ T cells are capable of expressing perforin and granzyme B. In conclusion, our data suggest that T-cell-mediated mechanisms involving cytotoxic granule proteins may elicit epidermal cell injury in vivo and thereby strongly contribute to the development of allergic contact dermatitis in humans.

Psoriasis beyond the skin: an expert group consensus on the management of psoriatic arthritis and common co-morbidities in patients with moderate-to-severe psoriasis

BACKGROUND Psoriatic arthritis (PsA) and co-morbidities of psoriasis represent a significant clinical and economic burden for patients with moderate-to-severe psoriasis. Often these co-morbidities may go unrecognized or undertreated. While published data are available on the incidence and impact of some of them, practical guidance for dermatologists on detection and management of these co-morbidities is lacking. OBJECTIVE To prepare expert recommendations to improve the detection and management of common co-morbidities in patients with moderate-to-severe psoriasis. METHODS A systematic literature review was conducted on some common co-morbidities of psoriasis-cardiovascular (CV) diseases (including obesity, hypertension, hyperglycaemia and dyslipidaemia), psychological co-morbidities (including depression, alcohol abuse and smoking) and PsA-to establish the incidence and impact of each. Data gaps were identified and a Delphi survey was carried out to obtain consensus on the detection and management of each co-morbidity. The expert panel members for the Delphi survey comprised 10 dermatologists with substantial clinical expertise in managing moderate-to-severe psoriasis patients, as well as a cardiologist and a psychologist (see appendix) with an interest in dermatology. Agreement was defined using a Likert scale of 1-7. Consensus regarding agreement for each statement was defined as ≥75% of respondents scoring either 1 (strongly agree) or 2 (agree). RESULTS The expert panel members addressed several topics including screening, intervention, monitoring frequency, and the effects of anti-psoriatic treatment on each co-morbidity. Consensus was achieved on 12 statements out of 22 (3 relating to PsA, 4 relating to psychological factors, 5 relating to CV factors). The panel members felt that dermatologists have an important role in screening their psoriasis patients for PsA and in assessing them for psychological and CV co-morbidities. In most cases, however, patients should be referred for specialist management if other co-morbidities are detected. CONCLUSION This article provides useful and practical guidance for the detection and management of common co-morbidities in patients with moderate-to-severe psoriasis.

Adalimumab in recalcitrant severe psoriasis associated with atopic dermatitis

Tumor necrosis factor-α inhibitors may induce various cutaneous side effects including eczematous-like lesions. The management of such side effects can be challenging. Herein, we report a case of a 55-year-old man who had a flare-up and subsequent improvement of atopic dermatitis during treatment of severe psoriasis with adalimumab.

Innate immune cells express IL-17A/F in acute generalized exanthematous pustulosis and generalized pustular psoriasis.

Acute generalized exanthematous pustulosis (AGEP) and generalized pustular psoriasis (GPP) are rare pustular skin disorders with systemic involvement. IL-17A/F is a proinflammatory cytokine involved in various neutrophilic inflammatory disorders. Here we show that IL-17A/F is highly expressed by innate immune cells such as neutrophils and mast cells in both AGEP and GPP.
