RESUMO

OBJECTIVE: Pulmonary disease is a major cause of excess mortality among patients with rheumatoid arthritis (RA). Interstitial lung disease (ILD) is a feared complication, but the benefit of screening is unknown. The aim of this study was to assess the frequency of pulmonary disease, including ILD, in early RA. METHOD: Patients with newly diagnosed RA were recruited prospectively at a single centre and underwent systematic pulmonary function tests (PFTs) and computed tomography (CT) scans at inclusion and after two years. RESULTS: The study included 150 patients (mean age 57 years, 63% female; 59% current or former smokers). Of these, 136 underwent baseline PFTs and 137 CT. Mean forced expiratory volume in one second was 99% predicted and forced vital capacity 106%. Mean diffusing capacity of the lungs for carbon monoxide (DLCO) was 84% predicted. Frequently detected CT abnormalities were pulmonary nodules (42%), bronchiectasis (29%), and emphysema (20%). Two patients had clinically significant ILD and six had mild reticulation suggestive of preclinical ILD. No ILD progression was identified at two-year follow-up. Smoking was associated with DLCO<80% (p=0.004), combined hyperinflation and diffusion impairment (residual volume>120% and DLCO<80%) (p=0.004), and visual emphysema on CT (p<0.001). CONCLUSION: Emphysema and bronchiectasis were common, but most patients had mild disease with preserved lung function. Preclinical or clinical ILD was seen in a minority in this early phase of RA. These findings suggest symptom-based screening and primary intervention focusing on smoking cessation rather than screening for ILD at the time of RA diagnosis.

RESUMO

BACKGROUND: Psoriasis has a large negative impact on quality of life and is associated with both depression and anxiety. The introduction of biologics has improved treatment outcomes, but the ways in which patients perceive these improvements are not well characterized. OBJECTIVES: To investigate the everyday life experiences of patients with psoriasis receiving biological treatment in order to gain an understanding of their needs and to improve the quality of care. METHODS: A qualitative narrative methodology was utilized. In total 48 h of participant observations during consultations, and 15 semistructured interviews, were conducted with patients receiving biological treatment. Data were analysed according to Ricoeur's theory of interpretation. RESULTS: Receiving biological treatment was experienced as a turning point, with a significant impact on physical, psychological and emotional levels. However, psychological consequences, such as isolation and social withdrawal, seemed to be a part of the patient's identity; the negative perceptions of psoriasis left marks behind that affected the patient's self-image. Perceived fear of discontinuation of the biological treatment resulted in insecurity, and patients were reluctant to initiate discussion about these concerns with healthcare professionals. CONCLUSIONS: Providing assistance when patients enter the transition of receiving biological treatment may be important. Patients' fear of biological treatment being discontinued is an ongoing issue that healthcare professionals could address.

RESUMO

BACKGROUND: The reported real-life use of prescribed topical antipsoriatic drugs is conflicting and based on heterogeneous data sources. OBJECTIVES: To describe the utilization of topical antipsoriatic drugs among patients with psoriasis in Denmark. METHODS: A drug utilization study was performed based on nationwide Danish health registry data. We identified patients who received a first-time hospital diagnosis of psoriasis and redeemed at least one topical drug prescription in the period 2005-2015 (n = 7743). Patients were followed for 3 years from the time of diagnosis. Use of topical and systemic antipsoriatic drugs was described, specified by the type of treatment. RESULTS: The total use of topical drugs was divided between corticosteroids with calcipotriol (31%), calcipotriol (6·5%), very potent corticosteroids (24%), potent corticosteroids (30%), moderate corticosteroids (7·2%) and corticosteroids with antimicrobials (1·6%). There was a 19% reduction in the overall use of topical drugs during the study period. Use increased around the time of diagnosis and the majority of patients redeemed more than two packages of topical drugs during the first year after being diagnosed. Regional differences in patients' use of topical drugs varied considerably. The distribution of use of topical drugs was uneven, with a minority of all patients (25%) using 70% of the total amount of topical treatment. There was a 70% increase in the use of methotrexate over the study period. Biologics were used by up to 6%. CONCLUSIONS: The study provides further evidence that the use of topical antipsoriatic drugs shows considerable heterogeneity over time and regional practices, and differences between patients.

RESUMO

BACKGROUND: Adherence to topical psoriasis treatments is low, which leads to unsatisfactory treatment results. Smartphone applications (apps) for patient support exist but their potential to improve adherence has not been systematically evaluated. OBJECTIVES: To evaluate whether a study-specific app improves adherence and reduces psoriasis symptoms compared with standard treatment. METHODS: We conducted a randomized controlled trial (RCT, clinicaltrials.gov registration: NCT02858713). Patients received once-daily medication [calcipotriol/betamethasone dipropionate (Cal/BD) cutaneous foam] and were randomized to no app (n = 66) or app intervention (n = 68) groups. In total, 122 patients (91%) completed the 22-week follow-up. The primary outcome was adherence, which was defined as medication applied ≥ 80% of days during the treatment period and assessed by a chip integrated into the medication dispenser. Secondary outcomes were psoriasis severity measured by the Lattice System Physician's Global Assessment (LS-PGA) and quality of life, measured using the Dermatology Life Quality Index (DLQI) at all visits. RESULTS: Intention-to-treat analyses using regression was performed. More patients in the intervention group were adherent to Cal/BD cutaneous foam than those in the nonintervention group at week 4 (65% vs. 38%, P = 0·004). The intervention group showed a greater LS-PGA reduction than the nonintervention group at week 4 (mean 1·86 vs. 1·46, P = 0·047). A similar effect was seen at weeks 8 and 26, although it did not reach statistical significance. CONCLUSIONS: This RCT demonstrates that the app improved short-term adherence to Cal/BD cutaneous foam treatment and psoriasis severity.

RESUMO

The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of magnesium sulfate, which functions as a bulking agent in cosmetic products and is reportedly used at concentrations up to 11% and 25% in leave-on and rinse-off products, respectively. The Panel noted that the history of safe medical use of magnesium sulfate provides further confidence that there are no significant toxicity concerns relating to systemic exposure to this ingredient after cosmetic product application. Furthermore, the extensive clinical experience of the Panel, including the results of numerous patch tests, indicates that magnesium salts do not have the potential to induce sensitization. The Panel also noted that results were negative for 50% magnesium sulfate in a mouse skin irritation study and in an in vitro sensitization assay. The Panel concluded that magnesium sulfate is safe in cosmetics in the present practices of use and concentration described in the safety assessment.

RESUMO

The Cosmetic Ingredient Review (CIR) Expert Panel (Panel) reviewed the product use, formulation, and safety data on hydrolyzed wheat protein and hydrolyzed wheat gluten, which function as skin- and hair-conditioning agents. The Panel determined that data from clinical and laboratory studies were sufficient to demonstrate that these ingredients will not elicit type 1 immediate hypersensitivity reactions in sensitized individuals and will not induce sensitization when the polypeptide lengths of the hydrolysates do not exceed 30 amino acids. The Panel concluded that hydrolyzed wheat gluten and hydrolyzed wheat protein are safe for use in cosmetics when formulated to restrict peptides to an average molecular weight of 3,500 Da or less.

RESUMO

The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of 11 alkyl betaines as used in cosmetics. These ingredients are reported to function as hair and skin conditioning agents, antistatic agents, surfactants-cleansing agents, and viscosity-increasing agents in cosmetic products. Although there are data gaps, the shared chemical core structure, similar functions and concentrations of use in cosmetics, and the expected similarities in physicochemical properties enabled grouping these ingredients and reading across the available toxicological data to support the safety assessment of each individual compound in the entire group. The Panel concluded alkyl betaines were safe as cosmetic ingredients in the present practices of use and concentration, when formulated to be nonirritating.

RESUMO

The Cosmetic Ingredient Review (CIR) Expert Panel (Panel) assessed the safety of 39 polyether lanolin ingredients as used in cosmetics. These ingredients function mostly as hair conditioning agents, skin conditioning agent-emollients, and surfactant-emulsifying agents. The Panel reviewed available animal and clinical data, from previous CIR safety assessments of related ingredients and components. The similar structure, properties, functions, and uses of these ingredients enabled grouping them and using the available toxicological data to assess the safety of the entire group. The Panel concluded that these polyether lanolin ingredients are safe in the practices of use and concentration as given in this safety assessment.

RESUMO

The Cosmetic Ingredient Review Expert Panel (Panel) reviewed the safety of polyethylene glycol (PEG)-150 pentaerythrityl tetrastearate, which functions as a viscosity-increasing agent-aqueous in cosmetic products and is being used at concentrations up to 5%. Given the chemical structure (large molecule), skin penetration is not likely. The available toxicity data and the low ingredient use concentrations suggest that systemic toxicity would not be likely even if percutaneous absorption were to occur. Additionally, the negative human repeated insult patch test data on the undiluted ingredient were deemed sufficient for evaluating skin irritation and sensitization potential. The Panel concluded that PEG-150 pentaerythrityl tetrastearate is safe in cosmetics in the present practices of use and concentration described in this safety assessment.
