Omalizumab is effective and safe in chronic inducible urticaria (CIndU): Real-world data from a large multi-national UCARE study.

BACKGROUND: Long-term data on the effectiveness and safety of omalizumab for chronic inducible urticaria (CIndU) in large populations are lacking. OBJECTIVE: To evaluate the effectiveness, safety, estimated omalizumab treatment duration and its predictors, as well as differences between CIndU subtypes, in a large long-term CIndU cohort. METHODS: A multinational multicenter study was conducted at 14 specialized urticaria centres (UCAREs), including all CIndU patients ever treated with omalizumab from 2009 until July 2022. Kaplan-Meier survival and regression analyses were performed. RESULTS: Across 234 CIndU patients (55% female; mean age 37 years), 76% (n = 178) had standalone CIndU and 24% (n = 56) had predominant CIndU plus minor CSU, with an observation period up to 13 years. Most CIndU patients (73%, n = 145/200 with available data on response) had complete/good response to omalizumab treatment, without significant differences between CIndU subtypes. Sixty-two (26%) patients discontinued omalizumab; due to well-controlled disease (47%, n = 29), ineffectiveness (34%, n = 21), side effects (3%, n = 2), combination of ineffectiveness and side effects (3%, n = 2) and other reasons (13%, n = 8). The median estimated omalizumab treatment duration exceeded 5 years (54% drug survival at 5 years) and was mostly determined by well-controlled disease. Higher age predicted a lower chance to discontinue omalizumab due to well-controlled disease (HR 0.969, 95%CI 0.945-0.995). CIndU subtype and presence of minor CSU were not related to response and time until omalizumab discontinuation for any reason. CONCLUSION: Omalizumab is highly effective and safe in CIndU patients, with long estimated treatment duration mainly reflecting long disease duration. Our data show omalizumab's high potential as treatment in any subtype of CIndU and support its clinical use for these patients.

European guideline (EuroGuiDerm) on atopic eczema: part I - systemic therapy.

The evidence- and consensus-based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were held between December 2020 and July 2021. Twenty-nine experts (including clinicians and patient representatives) from 12 European countries participated. This first part of the guideline includes general information on its scope and purpose, the health questions covered, target users and a methods section. It also provides guidance on which patients should be treated with systemic therapies, as well as recommendations and detailed information on each systemic drug. The systemic treatment options discussed in the guideline comprise conventional immunosuppressive drugs (azathioprine, ciclosporin, glucocorticosteroids, methotrexate and mycophenolate mofetil), biologics (dupilumab, lebrikizumab, nemolizumab, omalizumab and tralokinumab) and janus kinase inhibitors (abrocitinib, baricitinib and upadacitinib). Part two of the guideline will address avoidance of provocation factors, dietary interventions, immunotherapy, complementary medicine, educational interventions, occupational and psychodermatological aspects, patient perspective and considerations for paediatric, adolescent, pregnant and breastfeeding patients.

European guideline (EuroGuiDerm) on atopic eczema - part II: non-systemic treatments and treatment recommendations for special AE patient populations.

The evidence- and consensus-based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were held between December 2020 and July 2021. Twenty-nine experts (including clinicians and patient representatives) from 12 European countries participated. This second part of the guideline includes recommendations and detailed information on basic therapy with emollients and moisturizers, topical anti-inflammatory treatment, antimicrobial and antipruritic treatment and UV phototherapy. Furthermore, this part of the guideline covers techniques for avoiding provocation factors, as well as dietary interventions, immunotherapy, complementary medicine and educational interventions for patients with atopic eczema and deals with occupational and psychodermatological aspects of the disease. It also contains guidance on treatment for paediatric and adolescent patients and pregnant or breastfeeding women, as well as considerations for patients who want to have a child. A chapter on the patient perspective is also provided. The first part of the guideline, published separately, contains recommendations and guidance on systemic treatment with conventional immunosuppressive drugs, biologics and janus kinase (JAK) inhibitors, as well as information on the scope and purpose of the guideline, and a section on guideline methodology.

The effect of anxiety, psychopathological symptoms and personality traits on response to treatment in male patients with anogenital warts: a prospective study.

BACKGROUND: In the era of precision medicine, identification of possible predictive factors of clinical response to treatment is fundamental. This need is particularly strong for anogenital warts (AGW), because there are several treatment modalities with different clearance and recurrence rates. However, data regarding the effect of mental health parameters on response to treatment in patients with AGW are lacking. OBJECTIVES: The purpose of the present study was to evaluate the association between patients' mental health parameters and AGW treatment outcomes. METHODS: This was a single-centre, prospective study that included newly diagnosed male patients with AGW. At their initial visit, all patients completed the State-Trait Anxiety Inventory (STAI), the Symptom Checklist-90-Revised (SCL-90-R) and the Eysenck Personality Questionnaire (EPQ) questionnaires, which evaluate anxiety, psychopathological manifestations and personality traits, respectively. All patients received cryotherapy until clearance of lesions and were followed up for 18 months for detection of recurrences. RESULTS: The study included 167 male patients. The mean number of days for AGW clearance was 89 ± 65. During the 18-month follow-up, 28% of participants showed a recurrence, after a mean number of 150 ± 132 days. No statistically significant association was detected between questionnaires scores and (a) time needed for AGW clearance, (b) time until 1st recurrence and (c) number of recurrences. CONCLUSION: If confirmed, our findings indicate that we may not need to modify our AGW treatment plan according to a patient's mental health profile.

Pilot study of 19 patients with severe pemphigus: prophylactic treatment with rituximab does not appear to be beneficial.

AIMS: To assess the efficacy and safety of rituximab in refractory pemphigus and the possible benefit of an additional prophylactic infusion at 6 months. METHODS: Seventeen patients with pemphigus vulgaris, 1 with pemphigus foliaceus and 1 with pemphigus vegetans were treated with 4 weekly infusions of rituximab (375 mg/m(2)). Nine patients received an additional prophylactic infusion after 6 months while the rest received no maintenance therapy. In case of recurrence, an additional single infusion was administered. RESULTS: Control of the disease was obtained after 3-8 weeks. End of the consolidation phase for all patients was observed after 16 weeks. Patients remained in full remission for 7-42 months. All immunosuppressive agents, including prednisone, were discontinued after 2-12 months. The disease relapsed in 5 out of 9 patients who received the additional prophylactic infusion, and in 3 out of 10 patients among those skipping the prophylactic additional infusion. CONCLUSION: One course of rituximab and treatment of relapses is highly effective and well tolerated in the treatment of refractory pemphigus. In this pilot study of 19 patients, the prophylactic infusion does not appear to have provided any additional benefit to the patients receiving it.

Efficacy of ustekinumab in nail psoriasis and improvement in nail-associated quality of life in a population treated with ustekinumab for cutaneous psoriasis: an open prospective unblinded study.

BACKGROUND: The objective of this open-label prospective unblinded study was to evaluate the efficacy of ustekinumab in nail psoriasis and the improvement of patient quality of life (QoL). METHODS: Twenty-seven patients with plaque psoriasis and fingernail involvement were treated with the standard ustekinumab regimen. Outcome measures were assessed at baseline and at weeks 4, 16, 28 and 40 using the nail psoriasis severity index (NAPSI). QoL was evaluated before and after treatment using the international onychomycosis-specific questionnaire. RESULTS: The pairwise comparisons showed statistically significant NAPSI reduction in 4, 16, 28 and 40 weeks compared to the baseline score. The mean NAPSI at week 40 was 2.00 ± 2.337. The international onychomycosis QoL scores were significantly improved at all time points (p < 0.001). No patient reported any adverse events. CONCLUSIONS: Even though no control group was used in this study, ustekinumab was effective and safe in the treatment of nail psoriasis.
