ABSTRACT
BACKGROUND: Systemic treatment options for psoriasis are limited for patients with recent neoplasia. OBJECTIVES: We report the real-life use of apremilast (APR) in patients with psoriasis and recent cancer. MATERIALS & METHODS: We conducted a retrospective, multicentre study in five hospitals and among 120 private dermatologists in the north of France from January 2015 to May 2021. We included patients treated with APR for psoriasis and suffering from an active cancer or who had been diagnosed with a cancer or treated for a cancer within the last five years. RESULTS: We included 23 patients diagnosed with a cancer, on average 2.6 years before the introduction of APR for psoriasis. In most patients, APR was specifically chosen due to oncological history. At 16±8 weeks, 55% (n=11/20) of patients had achieved PASI 50 score, 30% (n=6/20) PASI 75, 5% (n=3/20) PASI 90 and 37.5% (n=3/8) of them had a significant improvement in quality of life. Non-serious adverse events were observed in 65.2% (n=15/23) of patients (diarrhoea in 39%), resulting in discontinuation of treatment for 27.8%. The average duration of treatment was 303.8±252.4 days. For four patients, a recurrence or a progression of cancer was recorded during APR treatment. CONCLUSION: In our patients with both psoriasis and cancer, APR improved quality of life, with a good safety profile. A larger study, matched for type, stage and treatment of underlying cancer, would be necessary to draw further conclusions about the oncological safety of APR.

OBJECTIVE: To evaluate the efficacy and the tolerance of sulfasalazine in the treatment of chronic lupus erythematosus (CLE). PATIENTS AND METHODS: We prescribed sulfasalazine (2 g/d) for 18 patients with severe CLE, all of whom had contraindications for or treatment failure with antimalarial drugs and thalidomide. This study analyses their response to treatment, duration of therapy, reasons for stopping, adverse effects, and the influence of the N-acetyltransferase 2 (NAT2) phenotype. RESULTS: We observed 10 complete and 3 partial responses, and 4 patients maintained complete response for at least 7 years. Eight patients experienced adverse effects, and 2 needed to stop treatment (because of photosensitization and development of antinuclear antibodies). All side effects occurred in the first 3 months of treatment. None of the 18 patients developed systemic lupus erythematosus. Of the 10 complete responders, 9 were rapid acetylators (RA), while 4 of the 5 who failed to respond were slow acetylators (SA). Leukopenia and photosensitization were observed in SA patients, while different side effects occurred in RA patients (headaches, diarrhea, moderate increase in liver enzymes and antinuclear antibodies). CONCLUSION: These findings confirm our earlier reports and demonstrate that sulfasalazine can be used successfully to treat severe CLE. NAT2 genotyping before initiating treatment helps to identify potential responders and avoid side effects. In RA patients, sulfasalazine can be an alternative to thalidomide after antimalarial drugs, whereas in SA patients, it should remain a third-line treatment, to be used only after antimalarials and thalidomide.
