Real-world effectiveness and safety of bimekizumab for hidradenitis suppurativa: An ambispective observational study.

In this original research, we present the results in terms of effectiveness and safety of bimekizumab for hidradenitis suppurativa in real clinical practice. Results indicated significant improvement in all activity scores and patient-reported outcomes at week 16, including a notable decrease in mean IHS4 from 27.1 to 15.6 (p < 0.001), HS-PGA from 5.1 to 3.2 (p < 0.001), VAS pain from 8.3 to 4.7 (p < 0.001) and DLQI from 21.6 to 12.6 (p < 0.001). Bimekizumab, administered every 2 or 4 weeks, was well-tolerated with no discontinuations and no new safety concerns identified. These findings corroborate the drug's effectiveness and favourable safety profile observed in phase 3 clinical trials, supporting its use in real-world clinical practice for treating HS.

Efficacy and safety of adalimumab 80 mg in the treatment of psoriasis: a bicentric retrospective study.

Adalimumab (ADA) is a recombinant human monoclonal antibody indicated for the treatment of psoriasis that specifically inhibits tumor necrosis factor. Until recently we only had the presentation of 40 mg of ADA, being the standard dose in adults an initial administration of 80 mg, followed by 40 mg every 2 weeks. Newly the presentation of 80 mg of ADA has been commercialized, allowing the administration of the standard dose or a higher dose, with fewer injections. In this study, we retrospectively studied 11 patients with psoriasis who have received treatment with the presentation of 80 mg of ADA in two dermatology departments of two hospitals in Spain since its commercialization until June 2019. At the end of the study, an improvement in the mean final Psoriasis Area Severity Index (PASI) of all patients was observed, without any patient presenting any adverse effects. This study shows the efficacy and safety of 80 mg of ADA in a sample of 11 patients with psoriasis.

Giant pilomatrixoma: a distinctive clinical variant: a new case and review of the literature.

Pilomatrixoma is a benign adnexal tumor very common in pediatric age and in young adults that derives from follicular matrix cells. Although clinically it usually presents as a subcutaneous nodule of bluish color less than 3cm in size, multiple clinicopathological variants have been described in the literature. Among these we can find the giant pilomatrixoma, a rare clinical variant that reaches a size greater than or equal to 4cm and can simulate the clinical presentation of a malignant neoplasm. We report a 59-year-old man with an exophytic and ulcerated nodule in the left parotid region that was removed with the suspected diagnosis of a cutaneous squamous cell carcinoma. Histopathological analysis showed a proliferation of basaloid cells with areas of transition to ghost cells, under granulation tissue, hemorrhage, and an ulcerated epidermis. Thus, the diagnosis of giant pilomatrixoma was made. We reviewed the literature and found a total of 53 articles that report a total of 71 cases of giant pilomatrixoma. It is important to recognize this clinical subtype of pilomatrixoma because, apart from the possibility of being clinically confused with malignant lesions, the clinicopathological differential diagnosis must be made with the proliferating pilomatrixoma and pilomatrixcarcinoma.

Patient preference after switching guselkumab from prefilled syringe to an autoinjection pen in psoriasis and psoriatic arthritis patients.

BACKGROUND: We assessed pain, acceptability, patient preference, and tolerability of patients with psoriasis and psoriatic arthritis after switching guselkumab from a prefilled syringe to One-Press autoinjector pen. METHODS: Patients with psoriasis and psoriatic arthritis treated for at least 6 months with guselkumab syringe were recruited from Jan 2019 to Dec 2022. Gender, age, diagnosis, self-administration, and pain perception of guselkumab prefilled syringe were recorded. At the first visit, patients completed a post-auto-injection syringe questionnaire before starting auto-injection pen administration. After 2 and 6 months of guselkumab self-injection using the One-Press autoinjector pen, patient experience, adherence, preference, pain, and safety of each administration were assessed using post-guselkumab by One-Press autoinjector pen questionnaire. RESULTS: 40 patients [psoriasis n=34, psoriatic arthritis n=6] were included. All patients self-administered guselkumab by One-Press autoinjector pen. Pain at the injection site was significantly reduced with the use of the One-Press autoinjector pen. All patients considered that using One-Press autoinjector pen was easier than the syringe, 98% chose the pen as their preferred delivery system. CONCLUSION: The One-Press autoinjector pen for guselkumab administration is presented as a preferred option, with a high satisfaction and less painful compared to the administration of guselkumab in a prefilled syringe.
