Effectiveness and safety of tildrakizumab for the treatment of psoriasis in real-world settings at 24 weeks: A retrospective, observational, multicentre study by the Spanish Psoriasis Group.

BACKGROUND: Tildrakizumab is a humanized, IgG1/κ antibody that interacts with the p19 subunit of interleukin 23. It is approved for the treatment of moderate-to-severe plaque psoriasis. Real-world evidence on the effectiveness and safety of tildrakizumab is limited. OBJECTIVES: To assess the effectiveness and safety of tildrakizumab at 24 weeks in patients with moderate-to-severe plaque psoriasis in routine clinical practice. METHODS: Retrospective, observational, multicentre study including adult patients with moderate-to-severe plaque psoriasis treated with tildrakizumab under real-life conditions. Patient data were extracted from anonymized electronic medical records. Statistical analysis was performed using SPSS22. RESULTS: A total of 190 patients were included. About 53.9% were men with a mean age of 51.45 (SD 3.9) and a mean BMI of 29.13 (SD 6.21). About 79.8% (132 out of 190) of patients had previously received biological therapy (BT) and 17.3% (33 out of 191) had psoriatic arthritis. Baseline PASI was 10.7 (SD 6.53). Up to 109 patients reached Week 24 and at this point mean baseline PASI decreased to 1.7 (SD 4.8), representing an 88.79% mean PASI reduction. At 6 months, 87.1% and 40.3% of the treated patients achieved PASI ≤3 and ≤1, respectively. At Week 24 mean BSA decreased from 13.2 (SD 10.07) to 1.6 (SD 4.40) and mean DLQI went from 12.5 (SD 7.12) to 1.2 (SD 3.27). Multivariate analysis showed no differences when effectiveness was correlated with gender, obesity, psoriatic arthritis or prior exposure to BT. The rate of adverse events (AE) was 5.9% (11 out of 190), where infections were the most frequent AE (4 out of 11). One patient suffered a haemorrhagic ictus and one patient died due to causes unrelated to the study. CONCLUSION: Tildrakizumab was effective and safe in a large cohort of patients with moderate-to-severe plaque psoriasis treated in a routine clinical setting.

Clinicopathological characteristics of cutaneous and mucocutaneous leishmaniasis in patients treated with TNF-α inhibitors.

BACKGROUND AND OBJECTIVES: The increasing use of biologics in the treatment of inflammatory diseases has led to more cases of leishmaniasis in patients subjected to iatrogenic immunosuppression. The main objective was to describe the characteristics of the patients with cutaneous (CL) or mucocutaneous (MCL) leishmaniasis who were receiving a biological therapy at the time of diagnosis. PATIENTS AND METHODS: A multicenter retrospective study was design based on a cohort of patients diagnosed with CL or MCL. All patients who were being treated with biologicals were included. For each case, two matched non-exposed patients were included for comparison. RESULTS: 38 patients were diagnosed with CL or MCL while being treated with tumor necrosis factor alpha (TNF-α) inhibitors. Leishmaniasis presented more frequently as a plaque (58.3%) with a larger median lesion size (2.5 cm), ulceration (92.1%), and required a greater median number of intralesional meglumine antimoniate infiltrations (3 doses) (P < 0.05) than in non-exposed patients. We found no systemic involvement in patients being treated with anti-TNF-α. We did not find differences regarding the treatment characteristics whether biologic therapy was modified or not. CONCLUSIONS: Although management should be individualized, maintenance of biologic therapy does not seem to interfere with treatment of CL or MCL.

Ustekinumab en paciente con enfermedad de Crohn y psoriasis inducida por anti-TNF-¦Á / Ustekinumab in a patient with Crohn's disease and anti-TNF-¦Á-induced psoriasis

El tratamiento con farmacos antifactor de necrosis tumoral alfa (TNF-¦Á) en la enfermedad de Crohn es relativamente seguro aunque se han comunicado diferentes efectos secundarios cutaneos como la aparicion o exacerbacion de una psoriasis secundaria al tratamiento con anti-TNF-¦Á que, en ocasiones, puede llevar a la suspension del tratamiento. Por ello, son necesarias nuevas alternativas terapeuticas con nuevos mecanismos de accion. Se ha publicado que ustekinumab, un anticuerpo monoclonal que se une a la subunidad p40 de la interleucina 12/23, podrea inducir repuesta en pacientes con enfermedad de Crohn y ademas ha demostrado su eficacia en pacientes con psoriasis. Presentamos un caso de una paciente con enfermedad de Crohn que desarrollo psoriasis tras el tratamiento con 2 farmacos anti-TNF-¦Á (infliximab y adalimumab) que fue posteriormente tratada con ustekinumab con resolucion de las lesiones de la psoriasis y mantuvo la remision de la enfermedad de Crohn (AU)

Treatment with anti-tumor necrosis factor (TNF)-¦Á for Crohn's disease is relatively safe, although various cutaneous adverse effects have been reported such as the development or exacerbation of anti-TNF- ¦Á-induced psoriasis, which can sometimes lead to treatment withdrawal. Therefore, new alternative treatments with new mechanisms of action are required. Ustekinumab, a monoclonal antibody against the p40 subunit of interleukin 12/23, could induce response in patients with Crohn's disease and has demonstrated efficacy in patients with psoriasis. We present the case of a woman with Crohn's disease who developed psoriasis after treatment with two anti-TNF- ¦Á drugs (infliximab and adalimumab). The patient was subsequently treated with ustekinumab with resolution or psoriasis lesions and maintenance of remission of Crohn's disease (AU)
