On the Interdisciplinary Treatment and Management of Patients with Immune-Mediated Inflammatory Diseases. A Study on Patients' Personal Experiences and Perspectives.

Purpose: Immune-mediated inflammatory diseases (eg, axial spondylitis, psoriasis, psoriatic arthritis, Crohn's disease, ulcerative colitis, and hidradenitis suppurativa) are common diseases that exert an extensive effect on the health-related quality of life, particularly when multiple concomitant conditions are present. Previous reports indicate that the traditional siloed approach to care can lead to a lack of patient centricity and inefficient disease management. In this article, we aimed to evaluate an interdisciplinary program for the treatment of immune-mediated inflammatory diseases compared to routine clinical practice. Patients and Methods: This was a mixed-method study, combining qualitative and quantitative data. Patients with co-occurrence of ≥2 immune-mediated inflammatory diseases treated in an interdisciplinary clinic (n = 48) or traditional usual care (n = 17) answered open-ended questions about their care experiences. Two independent coders blinded to patients' treatment group coded three aspects of the narratives provided by the patients' responses: Themes, Emotional valence, and Personal growth (ie, redemption). Themes were analyzed descriptively to explore possible differences between patients assigned to the interdisciplinary clinic and patients assigned to the usual care setting. Group differences in patients' emotional experiences were assessed, and we examined potential group differences in positive personal growth. Results: Our findings indicate that an interdisciplinary combined clinic approach provides benefits for patients with multiple inflammatory diseases towards the usual setup. Patients experienced benefits on a number of specific quality-of-life themes including acceptance, optimism, disease understanding, personal growth, and better disease control. The narratives of the patients in the interdisciplinary group were significantly more emotionally positive and included more positive personal growth compared to the usual care group. Conclusion: The findings indicate a patient-reported benefit, especially from the holistic approach and cross-specialty combined consultations in an interdisciplinary clinic compared to usual specialized healthcare, which was underscored by narratives highlighting an overall improved quality of life.

Single-Centre Real-World Study on Drug Survival and Effectiveness of Brodalumab for Treatment of Psoriasis and Psoriatic Arthritis.

BACKGROUND: Clinical trials have established the efficacy of brodalumab in treatment of psoriasis and psoriatic arthritis. Real-world evidence is needed to fully evaluate the drug. OBJECTIVE: Here we investigate drug survival and clinical effectiveness of brodalumab in patients with psoriasis and psoriatic arthritis in a real-world setting. METHODS: This was a retrospective single-centre study enrolling patients receiving brodalumab for psoriasis at the Department of Dermatology, Aarhus University Hospital, Denmark. The primary endpoints were drug survival, reasons for discontinuation, percentage of patients achieving a Psoriasis Area and Severity Index (PASI) ≤ 2 and clinical effectiveness against psoriatic arthritis. RESULTS: Eighty-three patients were included (mean age 49.2 ± 17.4 years, 59.0% male, 9.6% bio-naïve, mean baseline PASI 10.9 ± 6.9). Twenty-seven patients discontinued treatment primarily due to ineffectiveness and adverse events (AEs). Kaplan-Meier-estimated 1-year drug survival was 65.7%. An absolute Psoriasis Area and Severity Index (PASI) ≤ 2 was achieved by 68.2% of patients at end of follow-up, by 70.0% at weeks 12-17 and by 76.2% after 40-60 weeks of treatment. Neither drug survival nor PASI ≤ 2 was associated with baseline PASI ≥ 10, body mass index ≥ 30, previous treatment with > 2 biologics or other IL-17 inhibitors in particular (P > 0.05). Psoriatic arthritis remission or partial remission was achieved by 10 out of 18 patients with psoriatic arthritis; treatment failure was reported in 5 patients. CONCLUSIONS: Brodalumab was effective against psoriasis and psoriatic arthritis in a real-world setting. The drug survival was lower than reported in other real-world settings.

Guselkumab, tildrakizumab, and risankizumab in a real-world setting: drug survival and effectiveness in the treatment of psoriasis and psoriatic arthritis.

BACKGROUND: Clinical trials have shown promising results for interleukin-23 inhibitors in the treatment of psoriasis. The drugs have been used in clinical practice since 2017. OBJECTIVE: To investigate the drug survival and effectiveness of interleukin-23 inhibitors in the treatment of psoriasis and psoriatic arthritis (PsA) in a real-world setting. METHODS: The study was a retrospective analysis of patients treated with either guselkumab, tildrakizumab, or risankizumab at the Department of Dermatology, Aarhus University Hospital, during the period from June 11 2018, to July 14 2021. RESULTS: A total of 80 patients were included. During the study, 19 patients discontinued treatment with an interleukin-23 inhibitor, and mean treatment duration (SD) was 61.4 weeks (43.7). Seventy-six patients (95%) had previous use of ≥1 biologic. One-year drug survival was 81.0%. Among patients, 64.3% achieved a Psoriasis Area and Severity Index (PASI) ≤ 2 at weeks 12-17; 61.3%, at weeks 40-60. There was no statistically significant difference between the drugs regarding the chance of achieving PASI ≤ 2 (p>.05). Twenty-two patients (27.5%) had PsA. Among these, 40.9% and 36.4% achieved complete remission and partial remission, respectively. CONCLUSIONS: Interleukin-23 inhibitors appear to have high and similar drug survival and effectiveness in patients with difficult-to-treat psoriasis and PsA.
