[Severe acne in autoinflammatory diseases]. / Schwere Akne bei Autoinflammationskrankheiten.

BACKGROUND: In recent years, acne has been described as a symptom of autoinflammatory diseases, such as PASH (pyoderma gangrenosum - PG, acne and suppurative hidradenitis - SH) and PAPASH (PG, acne, pyogenic arthritis, and SH). The pathogenesis of autoinflammatory diseases is not fully understood; however, based on the possible involvement of IL-1ß, the recombinant human interleukin-1 receptor antagonist anakinra has been used in the treatment of certain autoinflammatory diseases. METHODS: We describe two patients with severe acne and associated symptoms which led to the diagnosis PAPASH and PASH syndrome and who were treated with anakinra. RESULTS: In the patient with PASH syndrome, inhibition of inflammation and almost complete healing of ulcers was observed. In the patient with PAPASH syndrome, partial response was achieved. CONCLUSION: The therapeutic effect of anakinra in PASH syndrome and partly in PAPASH syndrome indicates an involvement of IL-1ß in acne-associated autoinflammatory diseases.

High density cholesterol level as predictor of clinical response to anti-TNF-alpha therapy in psoriatic patients.

Psoriasis is a common, chronic, inflammatory, and debilitating disease of the skin. Infliximab is a human/mouse chimeric anti-TNF-alpha antibody effective in the management of psoriasis. Availability of biomarkers for prediction of response, could optimize the therapeutic approach. The aim of this study was to identify predictors of clinical response to infliximab in psoriatic patients in the long-term treatment. Patients affected with psoriasis and suitable for treatment with infliximab were prospectively enrolled. Patients treated for a period longer than 96 weeks were included in the study and divided into high responders and low responders according to infliximab efficacy (PASI 90). A logistic regression analysis was used to explore independent association between high clinical response and possible biomarkers of prediction. A total of 112 patients were included for the analysis. Multiple regression analysis showed that high levels of HDL cholesterol and the short duration of psoriasis [OR 1.11 (CI 1.05-1.18) and OR 0.94 (CI 0.89-0.99)] predicted the most effective clinical response to infliximab. Our findings, which highlight a possible role for HDL cholesterol as clinical predictor for psoriasis treatment, are particularly noteworthy in the context of clinical strategies, but also suggest a possible role for lipid metabolism in aspects of psoriasis that deserves further investigation.

Prevalence and management of panic attacks during infliximab infusion in psoriatic patients.

BACKGROUND: Psoriasis is a chronic, inflammatory skin disease associated with anxiety and depression. Infliximab (IFX) is a human/mouse chimeric anti-TNF-α antibody effective in the treatment of psoriasis. OBJECTIVE: The aim of this study was to evaluate the prevalence of panic disorders in psoriatic patients during IFX infusions. METHODS: A retrospective study was performed on patients affected with psoriasis who were treated with IFX from 2002 to 2011 at a single center. Panic disorders were defined using the clinical criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. A population of dermatological patients under treatment with IVG, rituximab, apheresis, intravenous corticosteroids and antibiotics was considered as the control group. RESULTS: A total of 141 patients were evaluated. Of these, 6 (4.25%) experienced panic attacks during the infusion; 16 (11.3%) had a medical history of panic attack and of those 5/16 (31%) experienced panic attacks during IFX infusion. In the control group panic attacks were not recorded. CONCLUSION: We describe 6 cases of patients in whom panic attacks were triggered by IFX infusion. Premedication with oral benzodiazepine and a slow rate of infusion is recommended.
