Background. Although infliximab (IFX) has been available since 2005, there are very little data on the long-term drug survival of infliximab in real-life. Objective. Our aim was to identify and describe psoriasis patients treated with IFX for longer than 6 years. Methods. Psoriasis patients treated with IFX for longer than 6 years were retrospectively included. Demographic and clinical data were collected in May 2018. Results. Between January 2005 and December 2012, 43 patients were maintained on IFX for 6 years or longer. IFX was introduced as a 4.5 line of systemic therapy. The mean duration of IFX treatment was 8.5 years (6–12). In May 2018, 30 patients (70%) were still maintained on IFX at 4–6 mg/kg every 8–10 weeks with an efficiency of about 100%. IFX was stopped in 13 patients (30%) mainly for loss of efficacy in 6 patients (46%). Three patients developed solid cancer including bladder cancer, lung cancer, and prostate cancer. Limitation. Retrospective study. Conclusion. We report the efficacy and safety of IFX maintained for up to 12 years in psoriasis patients. The long-term use of IFX was associated with a high BMI confirming the critical role of weight-based dosing for this drug.
Mycoplasma pneumoniae induced rash and mucositis (MIRM) is a distinct entity of erythema multiforma spectrum. Observation: we report a case of a 19-year-old man hospitalised for multiple mucosal eruptions and hyperthermia for three days, in context of a pro-T lymphoblastic leukemia in complete cytological and molecular remission. Discussion: MIRM is a skin split of 0% – 10% body surface area, at least two mucosal sites involved, few skins including vesiculobullous or atypical targets and evidence of atypical pneumonia. Identification of MP is essential for the correct diagnosis of MIRM and even more differentiation of EM associated with herpes simplex virus and drug-associated. Conclusion: MIRM has a good prognosis with rare recurrence and seldom complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
