Tattoo complications in treated and non-treated psoriatic patients.

BACKGROUND: Tattooing is a widespread phenomenon, with an estimated prevalence of 10-30% in Western populations. For psoriasis patients, current recommendations are to avoid having a tattoo if the disease is active and they are receiving immunosuppressive treatments. Although scientific data supporting these recommendations are lacking, dermatologists are often reluctant to advocate tattooing in psoriasis patients. OBJECTIVE: We aimed to evaluate the frequency of tattoo complications in patients with psoriasis and determine whether the occurrence of complications was associated with psoriasis status and treatments received at the time of tattooing. METHODS: We performed a multicentre cross-sectional study. Adults with psoriasis were consecutively included and classified as tattooed or non-tattooed. Prevalence of complications associated with tattoos was then evaluated according to psoriasis onset and treatments. The study was divided into three parts, in which data were collected through a series of questionnaires filled in by the dermatologist. Complications included pruritus, oedema, allergic reaction/eczema, infection/superinfection, granuloma, lichenification, photosensitivity, Koebner phenomenon and psoriasis flare after tattooing. Diagnosis of complications was made retrospectively. RESULTS: We included 2053 psoriatic patients, 20.2% had 894 tattoos. Amongst non-tattooed patients, 15.4% had wished to be tattooed, with psoriasis being stated as a reason for not having a tattoo by 44.0% and 5.7% indicating that they planned to have a tattoo in the future. Local complications, such as oedema, pruritus, allergy and Koebner phenomenon, were reported in tattoos in 6.6%, most frequently in patients with psoriasis requiring treatment at the time of tattooing (P < 0.0001). No severe complications were reported. CONCLUSIONS: The rate of tattoo complications in psoriasis patients was low. Although the risk of complications was highest amongst patients with psoriasis requiring treatment at the time of tattooing, all the complications observed were benign. These results can be helpful for practitioners to give objective information to patients.

[Cutaneous foreign body granulomas following cervico-facial arterial embolization: Three cases]. / Granulomes cutanés à corps étrangers après embolisation artérielle de la sphère cervico-faciale : trois cas.

BACKGROUND: Foreign body granuloma is an inflammatory tissue reaction to exogenous material. Classically it appears on the face after aesthetic procedures. Herein we report for the first time three cases of facial granulomatous reactions to microbeads after arterial cervico-facial embolization. PATIENTS AND METHODS: Three patients underwent embolization of the facial arteries using Embogold® microbeads in a setting of epistaxis or tumoral hemostasis. Within 10 to 45 days painful, inflammatory, subcutaneous nodules appeared on the homolateral side of the face. Histological samples showed an inflammatory response with giant cells as well as the presence of microbeads in the skin. A favorable outcome was achieved with colchicine in one patient and with surgery in another; the third patient was lost to follow-up. DISCUSSION: The embolizing microspheres produced a local inflammatory reaction, with destruction of the vascular wall and bead migration to facial tissue leading to a granulomatous reaction. The occurrence of three cases within a period of few weeks, with several different operators and batches of products, is surprising considering the long-standing use of the product. There was no common comorbidity in the patients and no suggestion of trauma. Retrospective analysis of the product batches was normal. Gold staining could play a role in severe inflammatory response to Embogold® particles. CONCLUSION: These three cases illustrate the value of discussing potential foreign body granulomatous reaction in cases of facial nodules following cervico-facial embolization. Colchicine may offer a valuable therapeutic alternative.

[Psoriatic patients: Analysis of patients dissatisfied with their management]. / Patients atteints de psoriasis : analyse de la population insatisfaite de sa prise en charge.

BACKGROUND: The French are frequently regarded as grouchy. In a recent study, we observed a high proportion of patients initially consulting for psoriasis because they were dissatisfied with their previous therapy. We analyzed the characteristics of these patients. PATIENTS AND METHODS: This was a cross-sectional multicenter study in 40 centers belonging to the ResoPso (psoriasis treatment network) multicenter study group, with consecutive inclusions over a period of 11months in 2014. All adults (age>18 years) consulting for the first time for psoriasis at a center were included in the study. RESULTS: Among patients, 1205 were included, of whom 249 (20.3%) were consulting because of their dissatisfaction with treatment. In the univariate analysis, these patients were younger (P=0.02) and presented psoriasis that had begun earlier in life (P<0.0001). It consisted mostly of generalized plaque psoriasis (P=0.047) and more severe forms of psoriasis (PASI and/or DLQI score>10, P<0.02). There were fewer cases of psoriatic arthritis (P=0.01). The "dissatisfied" patients reported significantly more frequent use of topical treatments (P<0.0001) and alternative medicines (P=0.02), and more infrequent use of biologics (P=0.006) as well as longer treatment periods (P=0.0005). They consulted at hospitals (P=0.01) and had previously seen more GPs and dermatologists (P≤0.0008). There was no impact of gender on the dissatisfaction profile by either comorbidities (metabolic, blood pressure, alcohol and tobacco consumption, and depression), or socio-economic data. In the multivariate analysis, DLQI>10 (P=0.01; 95% CI: 1.01-1.07) and longer duration of care (P=0.004; 95% CI: 1.23-2.99) were associated with dissatisfaction. CONCLUSION: Twenty percent of our psoriatic patients seem dissatisfied with their treatment. It is difficult to draw a specific demographic and socioeconomic profile of dissatisfied patients. Only disease severity and possibly inadequate treatment at the initial consultation are associated with patient dissatisfaction. Explanations related to the individual patients and doctors may be proposed. Finally, while the French may be considered grouchy, the frequency of patient dissatisfaction seen in our study does not appear to be any greater than that observed in other countries.

Evaluation of risk factors for body weight increment in psoriatic patients on infliximab: a multicentre, cross-sectional study.

BACKGROUND: A significant weight gain has been reported in patients with psoriasis treated with anti-tumour necrosis factor-alpha agents. Among these patients, there are contradictory results about risk factors for weight gain. OBJECTIVE: Assessing risk factors for weight increment in psoriatic patients on infliximab (IFX). METHODS: This study was a 4-month, non-interventional, cross-sectional, multicentre study on adults with psoriasis performed in 19 French dermatological centres. All the patients who received IFX for at least 1 year were prospectively included, with retrospective analysis of data. Impact of sex, age, severity of the disease, cardiovascular and metabolic comorbidities, and previous and simultaneous systemic treatments on weight changes, was analysed. Weight gain was defined as an increment of more than 2% of baseline weight. RESULTS: Overall, 191 psoriatic patients (males: 68.6%; mean age: 46.9 years) were included. Mean weight gain was 1.6 kg (2.1%) after 1 year of IFX. Half (48.2%) suffered from a weight gain, and 9.9% from a weight increment of 10% or more. Baseline weight and Body Mass Index, and cardiovascular and metabolic comorbidities did not influence weight. Men (P=0.007) and patients with severe psoriasis (BSA, P=0.005) had a tendency to put on weight. Patients with a hospital dietary follow-up (P=0.01; OR=0.36 [0.16-0.79]) and patients on methotrexate (P=0.03; OR=0.41 [0.18-0.93]) during IFX treatment are thinner, in a multivariate analysis. CONCLUSION: Severe weight increment is frequent on IFX treatment, mainly in men, and patients with severe psoriasis. Dietary follow-up or simultaneous use of methotrexate could limit this weight increment.
